The surface wet cleaner module 300 includes a floor brush 301 and a body 302. A third flow path is formed inside the surface wet cleaner module 300, and a second mounting position 303 is formed on the body 302. The second mounting position 303 is configured to be connected and matched with the power module 100, so that the surface wet cleaner module 300 and the power module 100 are assembled to form a surface wet cleaner to perform a surface wet cleaner mode. In this state, the power supply assembly 101 is electrically connected to the surface wet cleaner module 300, and the first flow path is in communication with the third flow path.

In the cleaning device, the vacuum cleaner module 200 and the surface wet cleaner module 300 are provided separately. In performing cleaning, the surface wet cleaner module 300 can be configured to clean the ground as needed, and the vacuum cleaner module 200 can be configured to clean the three-dimensional space. The power module 100 can be assembled with the surface wet cleaner module 300 and the vacuum cleaner module 200 respectively to form a surface wet cleaner and a vacuum cleaner, which can provide power for them. The vacuum cleaner module 200 and the surface wet cleaner module 300 share the same power module 100, which saves a set of power module 100 compared to the combination of a surface wet cleaner and a vacuum cleaner, optimizes the structure of the product, and reduces production costs. Specifically, after the power module 100 and the vacuum cleaner module 200 are assembled together, there are at least three aspects of cooperation and connection. Firstly, the power module 100 and the vacuum cleaner module 200 will be matched and connected in physical structure to achieve the stability of the connection between the power module 100 and the vacuum cleaner module 200. Secondly, the power source assembly 101 of the power module 100 and the vacuum cleaner module 200 are electrically connected to provide stable power output for each electrical component in the vacuum cleaner module 200 by the power source assembly 101. Thirdly, the first flow path of the power module 100 will be matched and connected to the second flow path of the vacuum cleaner module 200, suction airflow is generated by the motor assembly 102 to suck air in the external environment into the second flow path, and then into the first flow path, which is finally discharged into the vacuum cleaner module 200 through the first flow path and discharged to the external environment through the vacuum cleaner module 200, achieving airflow circulation. Similarly, after the power module 100 and the surface wet cleaner module 300 are assembled together, there are at least three aspects of coordination and connection. Firstly, the power module 100 and the surface wet cleaner module 300 will be physically matched and connected to achieve the stability of the connection between the power module 100 and the surface wet cleaner module 300. Secondly, the power source assembly 101 of the power module 100 is electrically connected to the surface wet cleaner module 300 to provide stable power output for each electrical component in the surface wet cleaner module 300 through the power source assembly 101. Thirdly, the first flow path of the power module 100 will be matched and connected to the third flow path of the surface wet cleaner module 300, suction airflow is generated by the motor assembly 102 to suck air in the external environment into the third flow path, and then into the first flow path, and finally discharged from the first flow path to the surface wet cleaner module 300, and then discharged to the external environment by the surface wet cleaner module 300 to achieve airflow circulation.

As shown in FIGS. 1-11, the vacuum cleaner module 200 includes an air suction assembly 201, a dust collection assembly 202, a filtering assembly 203, and a grip part 205. The second flow path includes the internal spaces of the air suction assembly 201, the dust collection assembly 202, and the filtering assembly 203 that are communicated in series. The vacuum cleaner module 200 is divided into an upper region and a lower region in the longitudinal direction. The dust collection assembly 202 and the grip part 205 are arranged side by side in the lower region 15 in the transverse direction, and the filtering assembly 203 and the first mounting position 204 are arranged side by side in the upper region in the transverse direction. The filtering assembly 203 is located above the dust collection assembly 202, and the air suction assembly 201 is mounted on the dust collection assembly 202. The air suction assembly 201 and the grip part 205 are located on sides of the dust collection assembly 202 respectively. In the above structural layout of the vacuum cleaner module 200, the dust collection assembly 202 is introduced as a separation device for dust particles, which greatly improves the separation efficiency of the vacuum cleaner module 200. During operation, external airflow first enters the dust collection assembly 202 in the transverse direction by the air suction assembly 201, and then enters the filtering assembly 203 from the dust collection assembly 202 in the longitudinal direction, and then enters the first flow path in the power module 100 by the filtering assembly 203 in the transverse direction. With a multi-segmented line type of airflow path, the overall structure of the machine is made more compact, avoiding the vacuum cleaner module 200 from being too large in a single direction. According to one embodiment of the present disclosure, the dust collection assembly 202 and the bottom of the grip part 205 jointly support the vacuum cleaner module 200; or the bottom of the dust collection assembly 202 alone supports the vacuum cleaner module 200. The grip part 205 may include a top shell 2051, a bottom shell 2052, and a handle 2053, with the handle located between the top shell 2051 and the bottom shell 2052. The top shell 2051 and the bottom shell 2052 are respectively connected to the dust collection assembly 202, and a hollow space is formed between the handle 2053 and the dust collection assembly 202 to facilitate grasping the handle. A first mounting position 204 is formed between the top surface of the top shell 2051 and the filter assembly 203, and the top surface of the top shell 2051 and one end of the filter assembly 203 are configured to be assembled with the power module 100, to achieve matching connection with the power module 100.

As shown in FIGS. 1-11, the power module 100 has a cylindrical structure with a housing 103, the power source assembly 101 and the motor assembly 102 are both provided in the housing 103, which constitutes the outer profile of the power module 100. The cylindrical structure is convenient for users to grasp with one hand, thus eliminating the need for additional handle structures for the power module 100, simplifying the structure of the product. Moreover, the operability of one-hand grasping can be further improved by the recessed holding part 107. In some embodiments, the holding part 107 is provided in two, and the two holding parts 107 are symmetrically disposed on both sides of the housing 103. After the power module 100 is matched and mounted in the first mounting position 204, the axis of the power module 100 is parallel or coincident with the axis of the filter assembly 203, and the inlet of the first flow path is located at one end of the power module 100 in the axial direction. The inlet of the first flow path is sealedly connected to the outlet of the filter assembly 203.

Preferably, the power module 100 is engageable with the filter assembly 203, that is, one end of the power module 100 and one end of the filter assembly 203 are mutually inclusive. Most preferably, the end of the filter assembly 203 is sleeved outside the power module 100. On one hand, the way of engaging the power module 100 with the filter assembly 203 can achieve rapid assembly between the power module 100 and the filter assembly 203 and improve the stability of the connection between the power module 100 and the filter assembly 203. On the other hand, the way of engaging can reduce the lateral size of the product to a certain extent, making the product more portable when in using.

The axial dimension of the engaging part of the power module 100 and the filter assembly 203 can be specifically designed as needed, preferably being 3-10 mm. As an implementation in some embodiments, a first protrusion 104 can be formed on the end of the power module 100 that is fitting with the filter assembly 203. The diameter of the first protrusion 104 is smaller than that of the housing 2031. When performing assembly, the first protrusion 104 can be engaged with an end of the filter assembly 203, and the end faces of the filter assembly 203 abuts the housing 2031 to complete the engaging therebetween.

As shown in FIGS. 1-3, the power module 100 has a first assembly surface 108 and a second assembly surface 109. The first assembly surface 108 is located on a periphery of the power module 100 in a cylindrical structure, and the second assembly surface 109 is located on one end surface of the power module 100. Both the first assembly surface 108 and the second assembly surface 109 are used for cooperating with the vacuum cleaner module 200 or the surface wet cleaner module 300. The first assembly surface 108 is mainly configured to perform electrical connection and communication with the vacuum cleaner module 200 or the surface wet cleaner module 300, and is provided with a first electrical connector 106. The second assembly surface 109 is mainly configured for airflow communication with the vacuum cleaner module 200 or the surface wet cleaner module 300, and is used as a surface of air path. Specifically, the middle of the second assembly surface 109 of the power module 100 is a first air opening 110, which serves as an inlet of the power module 100, that is, the inlet of the first flow path. The second assembly surface 109 further has a second air opening 111 provided around the first air opening 110. The second air opening 111 is provided in a ring shape as a whole, and serves as the outlet of the power module 100, that is, the outlet of the first flow path.

In some embodiments, the motor assembly 102 is closer to the second assembly surface 109, compared with the power supply assembly 101, that is, in the vacuum cleaner, the motor assembly 102 is disposed between the filter assembly 203 and the power supply assembly 101. Since the motor assembly 102 is heavier than the power supply assembly 101, when the power module 100 is mounted on the vacuum cleaner module 200, the heavier motor assembly 102 is located in the middle of the vacuum cleaner, which can avoid the rear of the vacuum cleaner being heavier, making it easier for the user to hold and providing a better user experience.

Specifically, the area of the power module 100 where the first assembly surface 108 is located forms a second protrusion 112, which protrudes from the periphery of the cylinder structure of the power module 100. On one hand, the second protrusion 112 can make a certain limitation in fitting with the first mounting position 204 or the second mounting position 303 to assist in positioning assembly, and on the other hand, can be configured to set up the relevant structure of the first electrical connection 106. The second protrusion 112 can avoid increasing the diameter of the columnar structure of the power module 100, maintaining the advantage of not providing a handle for the power module 100, so that the power module 100 can meet the performance requirements of the power supply assembly 101 and the motor assembly 102 while also meeting the need for one-handed holding.

In some embodiments, the second protrusion 112 can be provided only in the middle region of the axial length of the power module 100. In some embodiments, the second protrusion 112 can extend along the axial direction of the power module 100 to the end where the second assembly surface 109 is located, as shown in FIG. 1. A recess matched with the second protrusion 112 is provided at the first mounting position of the vacuum cleaner module 200 or the second mounting position of the surface wet cleaner module 300, which can be used for guiding in mounting. In other embodiments, the second protrusion 112 can be formed only at the first electrical connector 106.

In some embodiments, the diameter of the power module 100 is 84-100 mm, which can be corresponding to the size for holding by human hand, and it is unnecessary to design a special holding structure for the power module 100 to facilitate the assembly, disassembly, and movement of the power module 100 by human hand. Since the power module 100 is not provided with a special handle structure, it needs to be held by one hand for taking and placing. The diameter of the power module 100 is too large, which may cause the operator to be unable to hold it with one hand. If the diameter of the power module 100 is too small, the power source assembly 101 and the motor assembly 102 inside the housing 103 cannot meet the performance requirements. The diameter of the power module 100 can be further optimized to be 84 mm-95 mm. The range of the ratio of the diameter of the power module 100 to the diameter of the motor assembly 102 inside can be selected as 1.2-2.5, and the range of the power of the motor assembly 102 is preferably 80 W-350 W.

In order to further optimize the structural layout of the vacuum cleaner module 200, the ratio of the diameter of the power module 100 to the diameter of the dust collection assembly 202 ranges from 0.7 to 1.1; after the power module 100 is matched and mounted in the first mounting position 204, the ratio of the lateral length of the vacuum cleaner module 200 to the lateral length of the exposed part of the power module 100 is 1.3-1.7. The lateral length and its ratio of the vacuum cleaner module 200 are required to meet the requirements of power performance on the one hand, while taking into account the overall layout of the vacuum cleaner, during designing. When the ratio of the lateral length of the vacuum cleaner module 200 to the lateral length of the exposed part of the power module 100 is 1.3-1.7, the power module 100 can cooperate with the vacuum cleaner module 200 to meet the corresponding power performance, and the center of gravity of the overall structure of the vacuum cleaner is closer to the middle of the vacuum cleaner, making the overall layout more compact and harmonious. When the user grasps the grip part 205 to move the vacuum cleaner, the user may have a better experience and the user experience is improved. The ratio of the longitudinal height of the vacuum cleaner module 200 to the longitudinal height of the grip part 205 is 1.8-2.8, the ratio of the lateral length of the vacuum cleaner module 200 to the longitudinal height is 1.3-1.6. The above structural design can make the overall dimensions of the vacuum cleaner module 200 more harmonious in both the horizontal and vertical directions, and the layout is more compact.

In order to improve the portability of the vacuum cleaner module 200 in using, the ratio of the diameter of the power module 100 to the weight of the vacuum cleaner module 200 is preferably in a range of 46-91 mm/kg. With the above proportional relationship being achieved, in a preferred embodiment, the lateral length of the vacuum cleaner module 200 is 310-350 mm, after the power module 100 is fitted and mounted in the first mounting position 204, the total lateral length of the filter assembly 203 and the power module 100 is 270-230 mm; after the power module 100 is fitted and mounted in the first mounting position 204, the lateral length of the exposed part of the power module 100 is 160-190 mm; the diameter of the dust collection assembly 202 is 90-115 mm; the longitudinal height of the vacuum cleaner module 200 is 220-240 mm; the longitudinal height of the grip part 205 is 85-120 mm, which can effectively reduce the overall height of the vacuum cleaner, thereby avoiding the height from being too high and the power module 100 located above from shaking, while also ensuring sufficient height space to allow a person's hand to reach in for holding operation. The sucking power of the vacuum cleaner module 200 is 15 W-90 W.

In this embodiment, the housing of the power module is made of plastic with high thermal conductivity (such as PA6, PA, PA66). The heat inside the power module can be transferred outside by means of the high thermal conductivity of the power module.

When the housing of the power module is made of plastic with high thermal conductivity, the housing has an “ice-like” effect. At room temperature, when a person holds the housing, they can clearly feel the cooling effect. This is because the thermal conductivity of this kind of housing is extremely high, and when the person touches the housing, the housing can quickly transfer the temperature of the person's hand outside, so that fast heat conduction and dissipation can be achieved, thus making user has an ice-like feeling. In order to achieve this effect, the thermal conductivity of the housing is no less than 1.5 W/(m·K). In this embodiment, preferably, the thermal conductivity of the housing is 2.5 W/(m·K).

In order to achieve the detachable assembly of the power module 100 and the vacuum cleaner module 200, the power module 100 is provided with a clamping part 105, and the top shell 2051 of the vacuum cleaner module 200 is provided with a first snap-fit element 206. After the power module 100 is matched and mounted in the first mounting position 204, the first snap-fit element 206 can be matched and connected with the clamping part 105, thereby the longitudinal position of the power module 100 and the vacuum cleaner module 200 is under limitation. Preferably, the first snap-fit element 206 is movably disposed on the top shell 2051, and the top shell 2051 is further provided with a locking part 207. The locking part 207 is configured to provide elastic driving force to the first snap-fit element 206, so that the first snap-fit element always has a tendency to move away from the filter assembly 203. The locking part 207 is preferably a spring. Specifically, the locking part 207 abuts the first snap-fit element 206 and moves the first snap-fit element 206 to the extreme position away from the filter assembly 203, so that the first snap-fit element 206 and the clamping part 105 are matched and clamped with each other.

In addition, in the embodiments of the present disclosure, both the vacuum cleaner module 200 and the surface wet cleaner module 300 are provided with electrical and physical buttons. The physical button can be, but not limited to, an unlock button, which is configured to achieve the detachable connection of the power module 100 with the vacuum cleaner module 200 and the surface wet cleaner module 300. The unlock button provided on the vacuum cleaner module 200 in the embodiments of the present disclosure is referred to as the first unlock button 213, and the unlock button provided on the surface wet cleaner module 300 is referred to as the second unlock button 314, for distinction.

For example, in order to adjust the locking part 207 and the first snap-fit element 206, the vacuum cleaner module 200 further includes a first unlock button 213, which is a physical button as mentioned above. The first unlock button 213 is fixedly connected to the first snap-fit element 206 and protrudes outside the vacuum cleaner module 200 for user's control. During the assembly of the power module 100, the first snap-fit element 206 is in the extreme position under the action of the locking part 207, and at this time, the power module 100 interferes with the first snap-fit element 206 during the assembling, to drive the first snap-fit element 205 to move against the driving force of the locking part 207, and make the first snap-fit element 205 snapped into the clamping part 105, and the locking part 207 enables the stable clamping of the first snap-fit element 205 and the clamping part 105. When it is necessary to remove the power module 100, it can be done by applying a force on the filter assembly 203 toward the first unlock button 213, and the first snap-fit element 205 is driven to squeeze the locking part 207, causing the first snap-fit element 205 to move toward the filter assembly 203 against the driving force of the locking part 207. The first snap-fit element 205 eventually disengages from the clamping part 105, to allow the power module 100 to be removed.

Furthermore, as shown in FIG. 2, an end of the second protrusion 112 of the power module facing the clamping part 105 is provided with an abutting slope 115, and a clamping groove 114 is formed between the abutting slope 115 and the clamping part 105. The clamping groove 114 is used for the first snap-fit element 206 to be inserted and move back and forth therein. The abutting slope 115 and the clamping groove 114 are connected in communication with each other. When the first unlock button 213 on the vacuum cleaner module 200 or the surface wet cleaner module 300 is pressed, during the pressing stroke of the first unlock button 213, the first snap-fit element 206 cooperating with the clamping part 105 is firstly disengaged from the clamping part 105, and then the slope of the first snap-fit element 206 continues to abut against the abutting slope 115 of the power module 100, which can make one end of the power module 100 (the end opposite to the second assembly surface 109) tilt upward, that is, make the end opposite to the second assembly surface 109 away from the first mounting position 204 and/or the second mounting position 303, which is convenient for users in disassembling. For example, the end opposite to the second assembly surface 109 is made away from the first mounting position 204, which may remind users and facilitate users in disassembling. In addition, in addition to providing the abutting slope 115, a spring can be provided in the area near the clamping part 105 of the power module or the area near the snap-fit element 206 of the vacuum cleaner module. When the first snap-fit element 206 is disengaged from the clamping part 105, the restoring force of the spring can be applied on the end of the power module 100 (the end opposite to the second assembly surface 109), to make the end of the power module 100 tilt upward for users to perform disassembling.

In order to achieve electrical connection between the power module 100 and the vacuum cleaner module 200, a first electrical connector 106 is provided on the first assembly surface 108 of the power module 100, and a second electrical connector 208 is provided on the top shell 2051 of the vacuum cleaner module 200. After the power module 100 is fitted and mounted in the first mounting position 204, the first electrical connector 106 and the second electrical connector 208 can be mated and connected with each other, thereby achieving electrical connection between the power module 100 and the vacuum cleaner module 200. An accommodation space is formed inside the grip part 205 for accommodating various circuit structures and control circuit boards.

In some embodiments, the dust collection assembly 202 includes a dust cup 2021 and a multi-cone cyclone separator disposed inside the dust cup 2021. The dust cup 2021 has a dust collection space inside, and the suction assembly 201 is provided on the dust cup 2021 and is in communication with the dust collection space. A multi-cone cyclone separator 2022 is provided inside the dust collection space to separate dust from the suction airflow. After the external airflow enters the multi-cone cyclone separator 2022, the separated dust particles are discharged into the dust cup 2021, and the separated airflow enters the filter assembly 203 from the top. A cover 2023 that can be opened is disposed at the bottom of the dust cup 2021 to open the dust collection space at any time to discharge the collected dust, and the multi-cone cyclone separator 2022 can be further removed to be cleaned. The angle between the axis of the multi-cone cyclone separator 2022 and the axis of the power module 100 is 30°-150°, so that the airflow path is a multi-segmented line, which is more harmonious and compact in the overall structure of the machine compared to a straight airflow path. More preferably, the angle between the axis of the multi-cone cyclone separator 2022 and the axis of the power module 100 is 90°. In order to obtain better dust-air separation performance, the ratio of volume of the dust collection assembly 202 to the volume of the vacuum cleaner module 200 is 2.5-6. Preferably, the vertical orthogonal projection of the power module 100 in the vacuum cleaner is at least partially coincident with the dust cup 2021 of the dust collection assembly 202, or the vertical orthogonal projection of the motor assembly 102 in the power module 100 is at least partially coincident with the dust cup 2021 of the dust collection assembly 202, so that the overall weight distribution of the machine is more balanced and the structure is more compact.

The filter assembly 203 in the vacuum cleaner module 200 is configured to further filter the suction airflow passing through the dust collection assembly 202. The filter assembly 203 includes a housing 2031 and a filter core 2032. The housing 2031 can be integrally formed with the dust cup 2021 of the dust collection assembly 202. The filter core 2032 is preferably a HEPA filter core 2032 to achieve better filtration. The power module 100 is provided with a third snap-fit element 113 at one end of the second assembly surface 109. When the power module 100 is assembled on the vacuum cleaner module 200, the third snap-fit element 113 can be buckled and connected to the housing 2031 of the filter assembly 203, which can effectively reduce the assembly gap. When the power module 100 is assembled on the surface wet cleaner module 300, the third snap-fit element 113 can be buckled and connected to the surface wet cleaner module 300, which can also effectively reduce the assembly gap.

In some embodiments, the vacuum cleaner module 200 has a fourth flow path in addition to the second flow path. After the power module 100 is assembled on the vacuum cleaner module 200 to form a vacuum cleaner, the air flow path of the vacuum cleaner during operation is the second flow path, the first flow path, and the fourth flow path in sequence. Specifically, the fourth flow path is provided inside the housing 2031 of the filter assembly 203, and extends along the axial direction of the filter assembly 203. The end of the filter assembly 203 facing the second assembly surface 109 of the power module 100 has third air opening(s) 209 located in the middle and fourth air opening(s) 210 provided around the third air opening(s) 209. In the embodiments, the fourth air openings 210 may be further configured to provided surrounding the third air opening(s) 209. The third air opening(s) 209 serves as the outlet of the second flow path and is configured to communicate with the first air opening 110 of the power module 100. The fourth air opening(s) 210 serve as the inlets of the fourth flow path and is configured to communicate with the second air opening 111 of the power module 100. During operation of the vacuum cleaner, the first flow path of the power module 100 is matched and communicated with the second flow path of the vacuum cleaner module 200 through the first air opening 110, and matched and communicated with the fourth flow path of the vacuum cleaner module 200 through the second air opening 111. After the motor assembly 102 is started, it generates suction airflow, which draws air from the outside into the second flow path. The airflow in the second flow path passes through the third air opening(s) 209 and the first air opening 110 in sequence and enters the first flow path. The airflow in the first flow path then passes through the second air opening 111 and the fourth air opening(s) 210 in sequence and enters the fourth flow path of the vacuum cleaner module, and finally is discharged to the external environment through the fourth flow path, achieving airflow circulation.

In some embodiments, as shown in FIGS. 15 and 16, the filter assembly 203 has a baffle 218 in the lower part at one end facing the second mounting surface 109 of the power module 100. The baffle 218 faces a portion of the second air opening 111 of the power module 100. After flowing out of the second air outlet 111, a portion of the airflow in the first flow path is blocked by the baffle 218. A heat dissipation path 219 (indicated by areas filled with black blocks in FIG. 16) is formed between the power module 100 and the grip part 205 of the vacuum cleaner module 200. Specifically, the heat dissipation path 219 is formed between the first mounting surface 108 and/or the second protruding 112 of the power module 100 and the top shell 2051 of the grip part 205. The baffle 218 is configured to guide a portion of the airflow from the second air opening into the heat dissipation path 219. When the vacuum cleaner module 200 and the power module 100 are separated, the entire machine does not operate and is in a free state as shown in FIG. 15. When the power module 100 is mounted on the vacuum cleaner module 200, a heat dissipation path 219 is formed between an outer surface of the power module 100 and the top shell 2051 of the vacuum cleaner module 200. When the entire machine starts operating, as shown in FIG. 16, the power supply assembly 101 in the power module starts supplying power to the motor assembly 102. Heat generated by the power supply assembly 101 is dissipated to the housing of the power module 103. At the same time, the motor assembly 102 starts operating and generates a suction airflow that draws air from outside into the second flow path. The airflow in the second flow path successively passes through the third air hold 209 and the first air hold 110 to enter the first flow path in the power module 100. The airflow in the first flow path flows out through the second air opening 111. A portion of the airflow flowing out of the second air opening 111 flows through the fourth air opening(s) 210 and enters a fourth flow path in the vacuum cleaner module 200, and is finally discharged to an external environment through the fourth flow path; a portion of the airflow flowing out of the second air opening 111 is blocked by the baffle 218 and directed into the heat dissipation path 219 by the baffle 218, and enters the external environment through the heat dissipation path 219. During this process, the heat on the power module 100 can be taken away by the airflow flowing through the heat dissipation path 219, thereby indirectly reducing the heat generated by the power source assembly 101 itself and preventing the power supply assembly 101 from overheating and being unable to be charged. The heat dissipation path 219 is essentially a relatively narrow assembly gap formed after the power module 100 is assembled with the vacuum cleaner module 200. The airflow from the second air opening 111 of the first flow path is driven by the motor assembly 102 and has a certain flow rate and flow velocity. When the airflow is blocked by the baffle 218 and directed into the narrow heat dissipation path 219, the internal air pressure will rapidly increase, making the airflow in the heat dissipation path have a longer flow path and faster flow velocity, improving the heat exchange effect.

In some embodiments, as shown in FIGS. 7-9, a plurality of air outlet holes 211 are provided on the periphery of the housing 2031, and the air outlet holes 211 are in communication with the fourth flow path, so that the airflow in the fourth flow path is finally discharged to the external environment through the air outlet holes 211.

In some embodiments, as shown in FIGS. 5 and 10, the housing 2031 of the filter assembly 203 is provided with a panel 212 at the end away from the power module 100. The panel 212 can be used as an auxiliary screen to display some parameters of the cleaning device during operation. In other examples, the panel 212 may be used not as a screen. The panel 212 can be further detachably fitted with the housing 2031, and the filter core 2032 inside the housing 2031 can be removed after the panel 212 is removed, thus achieving synchronous assembly of the panel 212 and the filter core 2032. In some embodiments, the fourth flow path extends to the assembly gap between the panel 212 and the housing 2031, so that the airflow in the fourth flow path can be discharged to the external environment through the assembly gap between the panel 212 and the housing 2031. the airflow path can be thus further extended and airflow noise can be reduced. The fourth flow path forms a seventh air opening 216 at the end of the housing 2031 facing the panel 212, so that the airflow in the fourth flow path can enter the assembly gap between the panel 212 and the housing 2031 through the seventh air opening 216, and be discharged to the external environment. Preferably, in the radial direction of the filter assembly 203, the outer edge of the panel 212 slightly protrudes from the outer edge of the seventh air opening 216, that is, the front projection of the panel 212 can completely cover the seventh air opening 216, so that the airflow from the seventh air opening 216 can be directly blocked by the panel 212, and thus the airflow discharged from the fourth flow path may not be directly discharged along the axial direction of the filter assembly 203, but is discharged outside under the blocking of the panel 212. The airflow from the fourth flow path can be prevented from directly rushing to the suction assembly 201, preventing the airflow from interfering with the suction of the vacuum cleaner.

As shown in FIGS. 1-3 and FIGS. 12-14, the surface wet cleaner module 300 includes a floor brush 301, a body 302, a sewage tank 304, and a clean water tank 305. The floor brush 301 is rotatably engaged with the body 302, and both the sewage tank 304 and the clean water tank 305 are disposed on the body 302. It should be noted that the body 302 in the embodiment of the present disclosure can be tilted forward and backward relative to the floor brush 301 in a rotation way, and can also be twisted left and right relative to the floor brush 301. Of course, the body 302 can also achieve both forward and backward tilting relative to the floor brush 301 in a rotation way and left and right twisting relative to the floor brush 301 at the same time. The forward and backward directions mentioned in the present disclosure document refer to the forward and backward directions of the surface wet cleaner module 300. For example, the roller brush 3011 of the floor brush 301 is provided on the front side of the floor brush 301. The left and right directions mentioned in the present disclosure document refer to the direction of the user when the surface wet cleaner module 300 is configured to clean the ground. When the user uses the surface wet cleaner module 300 to clean the ground, he or she will be behind the surface wet cleaner module 300, and from the user's perspective, his or her left side corresponds to the left side recorded in the present disclosure document, and his or her right side corresponds to the right side recorded in the present disclosure document.

The handle 306 can be further provided on the body 302, and is located at the top of the surface wet cleaner module 300 for the user to hold and control the surface wet cleaner module 300 by the buttons thereon. In order to allow the user to maintain an upright position as much as possible when using the cleaning device, without having to bend too much, and improve user's experience, an extension section 307 is provided between the handle and the body 302. The extension section 307 can be further designed to have a telescopic mechanism to adapt users of different heights, facilitating user access and improving operability.

The sewage tank 304 is configured to store the sewage sucked through the suction port of the floor brush 301. The sewage tank 304 is provided on the body 302, and thus the structure of the whole machine can be made compact and the inconvenience of using the floor brush 301 with a large volume of the whole machine can be prevented. The sewage tank 304 can be detachably connected to the body 302, so that the sewage tank 304 can be removed from the body 302 separately for cleaning.

The floor brush 301 is provided with a suction port, which is connected to the sewage tank 304 through a suction pipe, such as a flexible pipe. The body 302 is provided with an exhaust pipe, one end of which is connected to the sewage tank 304, and the other end is located at the second mounting position 303, which is configured to be connected with the first flow path of the power module 100. That is, the third flow path includes the suction port, the suction pipe, the sewage tank 304, and the internal space of the exhaust pipe, which are connected in sequence. When the power module 100 is working, negative pressure is generated in the third flow path, to generate suction force. The airflow sucks the dirt near the suction port from the suction port and takes the dirt from the suction pipe to the sewage tank 304. Then, the airflow takes some of the airflow from the sewage tank 304 into the exhaust pipe, and finally into the first flow path of the power module 100, which is discharged outside by the power module 100.

The clear water tank 305 is configured to contain cleaning solution such as clear water and detergent. The floor brush 301 is provided with a nozzle, and the clear water tank 305 and the nozzle are connected through a clear water pipe. After the cleaning solution in the clear water tank 305 is pumped out, it flows through the clear water pipe to the nozzle, which sprays the cleaning solution onto the to-be-cleaned surface or the roller brush 3011 of the floor brush 301, enabling the floor brush 301 to quickly clean the to-be-cleaned surface.

In the embodiment of the present disclosure, the clear water tank 305 and the sewage tank 304 are respectively disposed on the opposite sides of the main body 302. It is preferred to place the sewage tank 304 on the front side of the main body 302 and the clear water tank 305 on the rear side of the main body. The axes of the clear water tank 305 and the sewage tank 304 are preferably provided in parallel. The suction port of the floor brush 301 and the main body of the roller brush 3011 are also located on the front side of the surface wet cleaner module 300. The air flow path may be reduced and air flow loss may be decreased by providing sewage tank 304 on the front side of the main body 302.

In some embodiments, the second mounting position 303 is located on the side of the sewage tank 304 away from the floor brush 301. That is, after the power module 100 is mounted in the second mounting position 303, the power module 100 is disposed on the side of the sewage tank 304 away from the floor brush 301. Specifically, the front side of the body 302 is provided with a second mounting position 303 for mounting the power module 100 and a third mounting position 308 for mounting the sewage tank 304. A fixed part 309 protruding from the surface of the body 302 is provided between the second mounting position 303 and the third mounting position 308. The side of the fixed part 309 close to the floor brush 301 is configured to cooperate with the sewage tank 304, and the side of the fixed part 309 away from the floor brush 301 is configured to be assembled with the power module 100. The exhaust pipe can be directly provided in the fixed part 309 to be in communication with the sewage tanks 304 and the power module 100 on both sides. In some other embodiments, the second mounting position 303 is located on the side of the clear water tank 305 away from the floor brush 301, i.e., after the power module 100 is mounted in the second mounting position 303, the power module 100 is disposed on the side of the clear water tank 305 away from the floor brush 301.

As shown in FIGS., after the power module 100 is fitted and mounted in the second mounting position 303, the axis of the power module 100 is parallel or coincident with the axis of the sewage tank 304. The inlet of the first flow path is located at one end of the power module 100 in the axial direction, and the inlet of the first flow path is sealedly connected to the outlet of the exhaust pipe on the fixed part 309. Preferably, the power module 100 is inserted and fitted with the fixed part 309, that is, one end of the power module 100 and one end of the fixed part 309 are mutually inclusive. Most preferably, the end of the fixed part 309 is sleeved outside the power module 100. On one hand, the way of engaging the power module 100 with the fixed part 309 can achieve rapid assembly between the power module 100 and the fixed part 309 and improve the stability of the connection between the power module 100 and the fixed part 309. On the other hand, the way of such engaging can make the center of gravity of the power module 100 closer to the brush 301 to a certain extent, save users' effort and improve user experience in using. The axial dimension of the engaging parts of the power module 100 and the fixed part 309 can be specifically designed as needed, preferably being 3-10 mm. As an implementation in some embodiments, a first protrusion 104 is formed at the end of the power module 100 that is fitted with the fixed part 309. The diameter of the first protrusion 104 is smaller than that of the housing 2031. During assembly, the first protrusion 104 can be matched and inserted into the end of the fixed part 309, and the end surface of the fixed part 309 and the end surface of the housing 2031 are abutted to complete the insertion and fitting of the two parts.

In some embodiments, the fresh water tank 305 and the power module 100 have been at least partially overlapped in the extension direction of the body 302, or the power source assembly 101 in the power module 100 and the fresh water tank 305 have been partially overlapped, and the fresh water tank 305 and the sewage tank 304 have been at least partially overlapped in the extension direction of the body 302. The power module 100 includes the power source assembly 101 and the motor assembly 102, which are heavy, while the fresh water tank 305 and the sewage tank 304 are loaded with a large amount of liquid in using, therefore the spatial layout of the three directly affects the center of gravity of the surface wet cleaner module 300 as a whole, thereby affecting the user's experience. With the above layout settings, it is possible to ensure that the center of gravity positions of the fresh water tank 305, the sewage tank 304, and the power module 100 are maximally close to each other, so that the center of gravity of the device can be lower, making it easier to operate and providing a better user's experience.

In order to further optimize the structural layout of the surface wet cleaner module 300, the ratio of the diameter of the body 302 to the diameter of the power module 100 is 0.9-1.3; after the power module 100 is matched and mounted in the second mounting position 303, the ratio of the axial length of the body 302 to the axial length of the exposed part of the power module 100 is 3.4-4; the ratio of the diameter of the body 302 to the weight of the surface wet cleaner module 300 is 16.8-25 mm/kg. With the above proportional relationship, in a preferred embodiment, the diameter of the body 302 is 95-115 mm; after the power module 100 is matched and mounted in the second mounting position 303, the body 302 is in a vertical state, and the distance in vertical from the top of the power module 100 to the bottom of the floor brush is 610-660 mm; after the power module 100 is matched and mounted in the second mounting position 303, the body 302 is in a vertical state, and the distance in vertical from the bottom of the exposed part of the power module 100 to the bottom of the base or the bottom of the floor brush is 420-510 mm.

In order to achieve the detachable assembly between the power module 100 and the surface wet cleaner module 300, the body 302 of the surface wet cleaner module 300 may be provided with a second snap-fit element 313. After the power module 100 is fitted and mounted in the second mounting position 303, the second snap-fit element 313 can be matched and connected with the clamping part 105, thereby enabling the stable connection of the power module 100 and the surface wet cleaner module 300. As shown in FIG. 12, in order to adjust the second snap-fit element 313, the surface wet cleaner module 300 further includes a second unlock button 314. The second unlock button 314 is a physical button. The second unlock button 314 is fixedly connected to the second snap-fit element 313 and extends outside the surface wet cleaner module 300 to facilitate user's control. During the assembly of the power module 100, the second snap-fit element 313 is in the extreme position under the action of the internal elastic member. At this time, the power module 100 interferes with the second snap-fit element 313 during the assembling process, to drive the second snap-fit element 313 to move, so that the second snap-fit element 313 is engaged with the clamping part 105. When the power module 100 is to be removed, a force towards the fixed part 309 may be applied to the second unlock button 31. The second unlock button 314 drives the second snap-fit element 313 to move towards the fixed part 309. The second snap-fit element 313 is eventually disengaged from the clamping part 105, and the power module 100 is allowed to be removed. Further, as shown in the FIG., the end of the second protrusion 112 of the power module facing the clamping part 105 is provided with an abutting slope 115. A card slot 114 is formed between the abutting slope 115 and the clamping part 105, which is configured for the second snap-fit element 313 to be inserted and move back-and-forth therein. The abutting slope 115 and the card slot 114 are connected in communication with each other, and when the second unlock button 314 on the surface wet cleaner module 300 is pressed, the second snap-fit element 313 cooperating with the clamping part 105 first disengages from the clamping part 105, and then the slope of the second snap-fit element 313 keeps pressing against the abutting slope 115 of the power module 100. One end of the power module 100 (the end opposite to the second assembly surface 109) is thus tilted, i.e., the end opposite to the second assembly surface 109 becomes away from the second mounting position 303, which can prompt the user and facilitate the user's removing operation. In addition, in addition to the abutting slope 115, a spring can be provided in the area near the clamping part 105 of the power module or the area near the snap-fit element 313 of the surface wet cleaner module 300. When the second snap-fit element 313 is disengaged from the clamping part 105, the restoring force of the spring can push against one end of the power module 100 (the end opposite the second assembly surface 109), and the end of the power module 100 thus rises for user's disassembly. In order to achieve electrical connection between the power module 100 and the surface wet cleaner module 300, a third electrical connector 310 is provided on the body 302 of the surface wet cleaner module 300. After the power module 100 is matched and mounted in the second mounting position 303, the first electrical connector 106 on the first assembly surface 108 can be mated with the third electrical connector 310, thereby enabling electrical connection between the power module 100 and the surface wet cleaner module 300. An accommodation space is formed inside the body 302 for accommodating various circuit structures and control circuit boards. It should be noted that the power module 100 in the present disclosure only has one type of the first electrical connector 106, and the second electrical connector 208 and the third electrical connector 310 can be in the same type. No matter the power module 100 is connected to the second electrical connector 208 of the vacuum cleaner module 200 or the third electrical connector 310 of the surface wet cleaner module 300, such connection is made by the same first electrical connector 106, and thus the number of electrical connection structures on the power module 100 is reduced, the volume and weight of the power module 100 are also reduced, and the feasibility of one-hand grasping of the power module 100 is further improved. The first electrical connector 106, the second electrical connector 208, and the third electrical connector 310 can adopt various electrical connection structures in related technologies. For example, the first electrical connector 106 can be a set of electrical contacts provided on the power module 100, which are connected to the power supply assembly 101 inside the power module 100. The second electrical connector 208 can be a plug provided on the top shell 2051, which is one-to-one corresponding to the electrical contacts. The third electrical connector 310 can be a plug provided on the body 302, which is one-to-one corresponding to the electrical contacts. During the assembly of the power module 100, the electrical contacts can be inserted and cooperated with the plugs to achieve stable electrical connection.

In some embodiments, the surface wet cleaner module 300 has a fifth flow path in addition to the third flow path. After the power module 100 is assembled on the surface wet cleaner module 300 to form a surface wet cleaner, the air flow path of the surface wet cleaner during operation is the third flow path, the first flow path, and the fifth flow path in sequence. Specifically, the fifth flow path is disposed inside the body 302, and the fixed part 309 has a fifth air opening 311 located in the middle and a sixth air opening 312 disposed around the fifth air opening 311 at one end facing the second assembly surface 109 of the power module 100. The fifth air opening 311 serves as the outlet of the third flow path and is configured to communicate with the first air opening 110 of the power module 100. The sixth air opening 312 serves as the inlet of the fifth flow path and is configured to communicate with the second air opening 111 of the power module 100. During operation of the surface wet cleaner, the first flow path of the power module 100 is matched and communicated with the third flow path of the surface wet cleaner module 300 through the first air opening 110, and is matched and communicated with the fifth flow path of the surface wet cleaner module 300 through the second air opening 111. The airflow in the first flow path passes through the fifth air opening 311 and the first air opening 110 in sequence and enters the first flow path. The airflow in the first flow path then passes through the second air opening 111 and the sixth air opening 312 in sequence and enters the fifth flow path of the surface wet cleaner module 300. Finally, the airflow is discharged through the assembly gap of the body 302 to the external environment through the fifth flow path, achieving airflow circulation.

In addition, in order to quickly disassemble and assemble the handle 306 of the surface wet cleaner module 300, a handle quick release button 316 is provided on the top of the back of the body 302 of the surface wet cleaner module 300. The handle quick release button 316 is a recessed button, and the outer surface of the recessed button is lower than the contour surface of the top of the back of the body 302, which can prevent accidental touch. When the handle quick release button 316 is pressed, the handle 306 can be quickly removed from the body 302. When the handle 306 is to be reassembled, the handle 306 can be inserted into the handle plug-in tube 317 on the top of the body 302 until the bottom of the handle 306 is engaged and fixed with the handle plug-in tube 317.

In some embodiments, the power module 100 of the present disclosure may be provided with no buttons, and the buttons of the cleaning device are all provided on the vacuum cleaner module 200 and the surface wet cleaner module 300, which can limit the function of the power module 100 to only providing energy and power, making the product structure of the power module 100 more simply, facilitating the reduction of product volume and improving the feasibility of one-hand grasping.

The vacuum cleaner module 200 and the surface wet cleaner module 300 are both provided with electrical and physical buttons. When the power module 100 is mounted on the vacuum cleaner module 200, the physical buttons on the vacuum cleaner module 200 are configured to control the locking of the vacuum cleaner module 200 and the power module 100, and the electrical buttons on the vacuum cleaner module 200 are configured to control the operation of the power module 100. Similarly, when the power module 100 is mounted on the surface wet cleaner module 300, the physical buttons on the surface wet cleaner module 300 are configured to control the locking of the surface wet cleaner module 300 and the power module 100, and the electrical buttons on the surface wet cleaner module 300 are configured to control the operation of the power module 100.

The physical buttons on the vacuum cleaner module include a first unlock button 213, and the electrical buttons include a power button 214 and a mode button 215. For example, the buttons that may be provided on the vacuum cleaner module 200 include but not limited to the first unlock button 213, the power button 214, and the mode button 215. These buttons can be located at the upper end of the handle and within the reach of the thumb and index finger when the handle is gripped. As shown in the figure, the mode button 215 can be located at the end of the first mounting position 204, and the first unlock button 213 is located on the left side of the entire machine, so that the pressing direction of the first unlock button 213 faces the filter assembly 203 for easy operation.

Due to the fact that the power module 100 may no longer be provided with buttons, the power module 100 can be used as a controlled component after docking with the vacuum cleaner module 200 or the surface wet cleaner module 300. Specifically, when the switch button on the vacuum cleaner module 200 or the surface wet cleaner module 300 is pressed, the Trig trigger signal can be sent to the power module 100, and the power source assembly 101 of the power module 100 is awakened to start providing external power. The electrical signal is then transmitted to the vacuum cleaner module 200 or the surface wet cleaner module 300, which then sends the control signal to the motor assembly 102 of the power module 100 by a Tx terminal. The motor assembly 102 performs corresponding work according to the control signal. The display screen of the power module 200 displays different content when it is connected to the vacuum cleaner module 200 and the surface wet cleaner module 300, respectively. For example, the display screen may display the relevant content of the vacuum cleaner module 200 or the surface wet cleaner module 300. The display screen of the power module 200 is located at the end of the power module 200 away from the second assembly surface 109, which is convenient for users to check during use.

The cleaning device provided by the embodiments of the present disclosure can be combined with the vacuum cleaner module 200 and the surface wet cleaner module 300 by a detachable power module 100, and thus the cleaning device may serve as both a vacuum cleaner and a surface wet cleaner, and can be used in multiple cleaning scenarios and achieve multi-purpose use by one machine. In addition to the power supply assembly 101 for power supply and the motor assembly 102 for providing the power for air flow, it may be further necessary to add a display screen 116 and a WiFi module 117 on the power module 100. The display screen 116 is configured to facilitate the interface display of the power module 100 after the power module 100 is removed from either one of the vacuum cleaner module 200 and the surface wet cleaner module 300 and mounted on the other. The WiFi module is used for network distribution and OTA upgrade. In addition, a first main control MCU chip 217 for communication connection with the power module 100 is provided in the vacuum cleaner module 200, and a second main control MCU chip 315 for communication connection with the power module is provided in the surface wet cleaner module 300. The power source assembly 101 includes a battery pack and a battery control unit. In related technologies, the battery control unit is a combination of MCU chips and battery protection analog front-end (AFE). Due to insufficient serial port resources in the MCU chips, it cannot simultaneously support the communication functions of the battery pack, display screen 116, WiFi module 117, first main control board 217, and second main control board 315. Specifically, the power module 100 communicates with the first main control MCU chip 217 of the vacuum cleaner module 200 through only one pair of serial ports, and the power module 100 communicates with the second main control MCU chip 315 of the surface wet cleaner module 300 through only one pair of serial ports, while it is necessary to simultaneously transmit messages from the AFE module, display screen 116, WiFi module 117, and motor assembly 102. In this case, the actual delay of communication will become very high, data loss may be incurred correspondingly. In the OTA upgrade of the battery pack, the amount of data required to be transmitted by the WiFi module is too large, and thus such transmission needs the majority of the bandwidth of the serial port communication. However, due to the large amount of information to be transmitted with limited transmission bandwidth, it may be impossible to implement the OTA upgrade function of the battery pack.

In view of the above, the embodiments of the present disclosure further improve the cleaning device.

In some embodiments, as shown in FIG. 17, the power supply assembly 101 includes a battery pack and a battery control unit. The battery control unit includes a two-in-one control chip 118 and a forwarding MCU chip 119. The two-in-one control chip 118 integrates the functions of the MCU chip and the battery protection analog front end (AFE). The forwarding MCU chip 119 is configured to receive the information from the battery pack and control the display screen 116, WiFi module 117 and motor assembly 102. Then, the forwarding MCU chip 119 communicates with the first main control MCU chip 217 or the second main control MCU chip 315. With the forwarding function of the forwarding MCU chip 119, the problem of insufficient serial port resources of the MCU chip in the battery control unit in related technologies can be solved.

In the above embodiment, the first main control MCU chip 217 or the second main control MCU chip 315 cannot directly control the battery pack, the display screen 116, the WiFi module 117 and the motor component 102m, and has to conduct the control by means of the forwarding MCU chip 119, but there is only one communication serial port between the forwarding MCU chip 119 and the first main control MCU chip 217 or the second main control MCU chip 315. The transmission speed may be increased by increasing the main frequency of the first main control MCU chip 217 or the second main control MCU chip 315, but the bandwidth is limited and cannot meet the requirement of transmitting so much communication information at the same time. In view of this, in some embodiments, as shown in FIG. 18, the power supply assembly 101 includes a battery pack and a battery control unit. The battery control unit includes a two-in-one control chip 118 and the forwarding MCU chip 119, which integrates the functions of the MCU chip and the battery protection analog front end (AFE) function of the two-in-one control chip 118. The forwarding MCU chip 119 is configured to receive the messages from the battery pack, control the display screen 116 and the motor component 102, and then communicate with the first main control MCU chip 217 or the second main control MCU chip 315. The first main control MCU chip 217 or the second main control MCU chip 315 is connected to the WiFi module 117. With the forwarding MCU chip 119, the problem of insufficient MCU single chip serial port resources in the related technology may be solved. In addition, the bandwidth occupation of the previous embodiment may be reduced by directly connecting the WiFi module 117 to the first main control MCU chip 217 or the second main control MCU chip 315 for communication. In this embodiment, two sets of electrical connection ports can be provided between the power module 100 and the vacuum cleaner module 200, or between the power module 100 and the surface wet cleaner module 300. One set of electrical connection ports is used for the communication between the WiFi module 117 of the power module 100 and the body of the device, and the other set of electrical connection ports is used for the communication of other information between the power module 100 and the body of the device.

In the above two embodiments, the first main control MCU chip 217 of the vacuum cleaner module 200 or the second main control MCU chip 315 of the surface wet cleaner module 300 is used as the core control center to control the power module 100. In another embodiment, as shown in FIG. 19, the forwarding MCU chip 119 of the power module 100 can be directly used as the core control center. The power source assembly 101 includes a battery pack and a battery control unit. The battery control unit includes a two-in-one control chip 118 and a forwarding MCU chip 119. The two-in-one control chip 118 integrates the functions of the MCU chip and the battery protection analog front end (AFE). The forwarding MCU chip 119 is connected to the two-in-one control chip 118, the display screen 116, the WiFi module 117, and the motor assembly 102, respectively. The forwarding MCU chip 119 is configured to be connected with the first main control MCU chip 217 of the vacuum cleaner module 200 or the second main control MCU chip 315 of the surface wet cleaner module 300.

Please refer to FIG. 26 to FIG. 41. The present disclosure also provides a cleaning device, which can be a cleaning device known to those skilled in the art such as a sweeping robot, a surface wet cleaner robot, or a handheld sweeping-scrubber device. The cleaning device includes a body, on which a roller brush for cleaning the to-be-cleaned surface is provided, and a driving device that is connected to the roller brush and drives the roller brush to operate. The roller brush is provided with a roller brush cavity, and one end of the driving device can be fixedly connected to the body, and the other end extends into the roller brush cavity of the roller brush and is connected to the roller brush, so that it can drive the roller brush to move.

During the cleaning process of the cleaning device, the roller brush comes into contact with the to-be-cleaned surface, and the driving device drives the roller brush to rotate, so that the to-be-cleaned surface may be cleaned Specifically, the roller brush cavity extends along the axial direction of the roller brush, and a transmission base is provided in the roller brush cavity. The output end of the driving device extends into the roller brush cavity and is detachably connected to the transmission base in the roller brush cavity to drive the roller brush to rotate.

When it is required to remove the roller brush, the roller brush can be disengaged from the driving device; the roller brush can be engaged together with the driving device during assembly. The locking together in the present disclosure refers to the tendency of the transmission part and the cooperating part to move closer to each other during the forward rotation or reversal of the roller brush, without the tendency to disengage from each other.

The cleaning device of the present disclosure has an interference fit between the to-be-cleaned surface and the roller brush during cleaning process, and the driving device can drive the transmission base to drive the roller brush in forward and reverse rotations to perform cleaning. The roller brush can be prevented from rotating in the same direction for a long time, which may result in the bristles of the roller brush too close to the body. The cleaning ability of the roller brush can be improved with service life extended by switching the rotation direction of the roller brush.

For better understanding, the specific structure and working principle of the cleaning device of the present disclosure are described in detail below with reference to FIGS. 1 to 16 in conjunction with one embodiment.

Embodiment 1

The present disclosure provides a cleaning device, which can be a handheld cleaning device such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld surface wet cleaner, etc., which are well known to those skilled in the art. It can also be a self-moving cleaning device, such as a sweeping robot, a surface wet cleaner robot, or a robot that integrates functions of sweeping and scrubber, for to-be-cleaned surfaces such as floors, sofas, and carpets that need to be cleaned. Referring to FIG. 26 and FIG. 27, in the embodiment of the present disclosure where the cleaning device is a handheld surface wet cleaner, when the user uses the surface wet cleaner for cleaning work, the user can push the handheld part of the surface wet cleaner on the ground to move and use the roller brush assembly 62 of the surface wet cleaner to clean the to-be-cleaned surface. The roller brush assembly 62 of the present disclosure includes a roller brush housing 623, a roller brush 621, a scraper mechanism, etc. The roller brush 621 is rotationally connected to the roller brush housing 623, and the axis of rotation of the roller brush 621 is parallel to the to-be-cleaned surface. During the cleaning process, the to-be-cleaned surface, such as the floor, is cleaned by rotating the roller brush 621.

With reference to FIG. 26 and FIG. 27, the body 600 can be provided with functional components such as a water supply system and a sewage suction system, and the roller brush assembly 62 is further mounted on the body 600. The cleaning device can further include a moving mechanism 61 for the cleaning device to move and perform cleaning work. The moving mechanism 61 can be a plurality of driving wheels disposed on the body 600, which can be pushed forward or backward by the user to allow the cleaning device to move on the to-be-cleaned surface. Alternatively, when the cleaning device of the present disclosure is a cleaning robot, it can be driven by its own driving force to allow the cleaning device to move on the to-be-cleaned surface. There is no limitation on the structure other than the roller brush assembly 62 in the present disclosure, and those skilled in the art can make selection on the structure based on the existing technology.

Referring to FIGS. 28 and 29, the cleaning device of the present disclosure includes a body 600 and a roller brush assembly 62 disposed on the body 600. The roller brush assembly 62 includes a roller brush 621 for cleaning the to-be-cleaned surface, and a transmission base 622 connected to the roller brush 621 and driving the rotation of the roller brush 621. As shown in FIG. 28, the roller brush 621 has a roller brush cavity 6211 extending in its axial direction. One end of the driving device can be fixedly connected to the body 600, and the other end extends into the roller brush cavity 6211 and is connected to the transmission base 622, so as to drive the roller brush 621 to move.

In one embodiment of the present disclosure, referring to FIG. 28 and FIG. 31, the roller brush 621 can be a cylindrical cleaning roller with a rotation axis parallel to the to-be-cleaned surface. The roller brush cavity 6211 extends through its opposite first and second ends; the transmission base 622 is fixed in the roller brush cavity 6211 of the roller brush 621 and is coaxial with the roller brush cavity 6211. Cleaning cotton, bristles, or other components for cleaning can be provided on the outer surface of the roller brush 621.

Referring to FIG. 30 and FIG. 32, a transmission mechanism is provided between the transmission base 622 and the output end 6241 of the driving device 624. The transmission mechanism includes a transmission part 625 and a cooperating part that are engaged and fitted together. When the transmission part 625 and the cooperating part are assembled together, the transmission part 625 is configured to be driven by the driving device 624 to drive the roller brush 621 to rotate in forward and reverse direction by the cooperating part. Referring to the view direction of FIG. 27, when the user faces to the angle as shown in FIG. 27, when the roller brush 621 rotates forward, the transmission part 625 and the cooperating part rotate counterclockwise; when the roller brush 621 rotates backward, the transmission part 625 and the cooperating part rotate clockwise. During the rotation of the cooperating part, the transmission part 625 is configured to be locked together with the cooperating part to prevent the cooperating part from moving away from the transmission part 625 along its own axis direction in using, which may result in loosening and disengagement between the two parts along the axis direction of the roller brush 621.

One end of the driving device 624 is fixedly connected to the body 600. During assembly, referring to FIG. 28 and FIG. 31, one end of the transmission base 6221 in the roller brush assembly 62 is sleeved on the driving device 624, and the output end 6241 of the driving device 624 is engaged with the transmission base 622 in the roller brush cavity 6211. Under the driving by the driving device 624, the output end 6241 drives the transmission base 622 to rotate, thereby enabling the transmission base 622 to drive the roller brush 621 to rotate.

In one implementation of the present disclosure, the rolling brush 621 is in contact with the to-be-cleaned surface, and the external structure of the rolling brush 621, such as the bristles, gradually contact the body of the rolling brush 621 during long-term work, which may result in a gradual reduction in the interference between the rolling brush 621 and the to-be-cleaned surface, and the cleaning effect of the cleaning device becomes worse. At this time, the rotation direction of the rolling brush 621 can be changed by changing the current rotation direction of the driving device 624. In this way, it can be avoided that the rolling brush 621 performs cleaning work in a single direction for a long time, which may result in excessive fitting of the bristles and the body, and the water attached to the bristles can only stay on the surface of the rolling brush 621, eventually forms a layer of water film on the outer surface of the rolling brush 621, and water marks may be left on the to-be-cleaned surface during work and affecting the cleaning effect. Therefore, with the rotation direction of the rolling brush 621 changed by the driving device 624, the stability of the external structure of the rolling brush 621 may be maintained, the rolling brush 621 may be protected, the service life of the rolling brush 621 may be extended, and the cleaning performance of the rolling brush 621 may be improved. During cleaning on the to-be-cleaned surface performed by the cleaning device, the rolling brush can be driven to rotate forward or reverse; or when the cleaning device is placed on the base station for self-cleaning, the rolling brush can be driven to rotate forward or reverse.

In an embodiment of the present disclosure, in driving the cooperating part to rotate forward and reverse, the transmission part 625 is located on disengage path of the cooperating part to prevent the cooperating part from being disengaged. That is, during the cooperating part is driven by the transmission part 625 to rotate forward, the transmission part 625 is located on disengage path of the cooperating part; during the cooperating part is driven by the transmission part 625 to rotate reverse, the transmission part 625 is located on disengage path of the cooperating part, thereby the cooperating part may be prevented from being disengaged from the transmission part 625 during the forward or reverse rotation.

During disassembly, the roller brush 621 can be directly removed from the driving device 624. During the removal process, the transmission part 625 and the cooperating part in the transmission mechanism can be easily disengaged from each other, thereby the roller brush 621 may be removed from the driving device 624 for maintenance, cleaning, and other operations. In one embodiment of the present disclosure, referring to FIG. 33 and FIG. 34, the cooperating part includes a first abutting part 6261, and the transmission part 625 is configured to cooperate with the first abutting part 6261 in forward rotation. The first locking side formed by the contact between the transmission part 625 and the first abutting part 6261 is configured to prevent the first abutting part 6261 from moving in a direction away from the transmission part 625 in forward rotation.

In another embodiment of the present disclosure, with reference to FIGS. 33 and 34, the cooperating part further includes a second abutting part 6264, and the transmission part 625 is configured to cooperate with the second abutting part 6264 during reverse rotation. The second locking side formed by the contact of transmission part 625 and the second abutting part 6264 is configured to prevent the second abutting part 6264 from moving in a direction away from the transmission part 625 during reverse rotation.

FIGS. 36 to 38 are simplified schematic diagrams of the motion relationship between the transmission part 625 and the cooperating part in the cleaning device of the present disclosure. FIGS. 36 to 38 are simplified schematic diagrams from the perspective shown in FIG. 28. The left side of FIGS. 36 to 38 is the side of the driving device of roller brush, and the right side of FIGS. 36 to 38 is the side where the roller brush is mounted. The roller brush can be mounted or removed from this side, and it can be removed from the floor brush of the cleaning device along the detachment direction of roller brush DE shown in FIGS. 36 to 38. When the transmission part 625 drives the cooperating part to move upward as shown in the figure, i.e., the transmission part 625 drives the cooperating part to rotate clockwise (reverse rotation) as shown in FIG. 27; when the transmission part 625 drives the cooperating part to move downward as shown in the figure, i.e., the transmission part 625 drives the cooperating part to rotate counterclockwise (forward rotation) as shown in FIG. 27.

In an embodiment of the present disclosure, referring to the view direction of FIG. 36, the side walls of the transmission part 625 are referred as A1, B1, A2, B2, and the side walls of the cooperating part are referred as A1′, B1′, A2′, B2′. When the transmission part 625 is driven by the driving device 624 to drive the cooperating part to rotate counterclockwise, i.e., to rotate forward, referring to FIG. 37, the first abutting part 6261 of the cooperating part is in contact with the first transmission part 6251 of the transmission part 625, and a first locking side is formed therebetween. It can be understood that the side wall A2′ of the first abutting part 6261 and the side wall A2 of the first transmission part 6251 form a first locking side upon being engaged. The first abutting part 6261 and the first transmission part 6251 are configured to be inclined in the direction of force applied when rotating counterclockwise from one end adjacent to the driving device 624 to the other end away from the driving device 624, i.e., the first locking side has an inclination angle that prevents the first abutting part 6261 from being disengaged, and the first locking side may prevent the first abutting part 6261 from moving in the detachment direction of the roller brush DE, which may achieve the purpose of locking the cooperating part and the transmission part 625.

In one embodiment of the present disclosure, during forward rotation, the transmission part 625 is located on the disengage path of the first abutting part 6261, and there is a gap between the transmission part 625 and the second abutting part 6264. With reference to the view direction of FIG. 37, the first abutting part 6261 and the first transmission part 6251 are sequentially distributed in the disengage direction of the roller brush. The first transmission part 6251 has an inclination angle that prevents the first abutting part 6261 from being disengaged during forward rotation DF of the roller brush, i.e., the first transmission part 6251 and the first abutting part 6261 gradually tilt downward from the side adjacent to the driving device 624 to the side away from the driving device 624, with the first abutting part 6261 located below the first transmission part 6251. When the driving device 624 drives the transmission part 625 to drive the cooperating part to rotate counterclockwise, the cooperating part has a tendency to move in the direction away from the driving device 624, and the first locking side prevents the first abutting part 6261 from moving in this direction, so that the cooperating part is prevented from being disengaged and loosening.

In another embodiment of the present disclosure, when the transmission part 625 rotates clockwise with the cooperating part under the driving by the driving device 624, i.e., when it rotates in reverse, with reference to FIG. 38, the second abutting part 6264 of the cooperating part and the second transmission part 6252 of the transmission part 625 are fitted together to form a second locking side therebetween. It can be understood that the side wall B1′ of the transmission part 625 and the side wall B1 of the second abutting part 6264 are fitted together to form the second locking side. The second abutting part 6264 and the second transmission part 6252 are configured to be inclined in the direction of force applied when rotating clockwise from one end adjacent to the driving device 624 to the other end away from the driving device 624, therefore the second locking side has an angle opposite to that of the first locking side. The second locking side has a similar function to the first locking side, and is configured to have an inclination angle that prevents the second abutting part 6264 from being disengaged when rotating clockwise.

In reverse rotation, the transmission part 625 is located on the disengaging path of the second abutting part 6264, and there is a gap between the transmission part 625 and the first abutting part 6261. With reference to the view direction of FIG. 38, the second abutting part 6264 and the second transmission part 6252 are sequentially distributed in the disengagement direction of the roller brush. The second transmission part 6252 has an inclination angle that prevents the second abutting part 6264 from being disengaged when the roller brush is in reverse rotation DR. That is, the second abutting part 6264 and the second transmission part 6252 gradually tilt upward from the side adjacent to the driving device 624 to the side away from the driving device 624, and the second abutting part 6264 is located above the second transmission part 6252. In this way, the second locking side can prevent the second abutting part 6264 from moving in the direction away from the driving device 624 during the clockwise rotation, so as to prevent the cooperating part from being disengaged.

In one embodiment of the present disclosure, with reference to FIGS. 36 to 38, when the roller brush 621 rotates forward, the part of the transmission part 625 located on the disengaging path of the cooperating part is different from the part of the transmission part 625 located on the disengaging path of the cooperating part when the roller brush 621 rotates in reverse. With reference to the view direction of FIG. 37, when the roller brush 621 rotates forward, the transmission part 625 is located above the cooperating part, and the end of the transmission part 625 adjacent to the driving device 624 can block the cooperating part from being disengaged. Specifically, the first transmission part 6251 may cooperate with the first abutting part 6261 to prevent the first abutting part 6261 from being disengaged. With reference to the view direction of FIG. 38, when the roller brush 621 rotates in reverse, the transmission part 625 is located below the cooperating part, and the end of the transmission part 625 away from the driving device 624 can block the cooperating part from being disengaged. Specifically, the second transmission part 6252 may cooperate with the second abutting part 6264 to prevent the second abutting part 6264 from being disengaged. In one embodiment of the present disclosure, with reference to FIGS. 32 and 34, the transmission part 625 is disposed on the output end 6241 of the driving device 624. The transmission base 622 has a transmission base 6221, and the cooperating part is a fitting groove 626 disposed on the transmission base 6221. The first abutting part 6261 and the second abutting part 6264 are the groove walls on opposite sides of the fitting groove 626. In this embodiment, with reference to FIGS. 28 and 33, the transmission base 6221 extends in the axial direction of the roller brush cavity 6211 of the roller brush 621. After the output end 6241 of the driving device 624 extends into the transmission base 6221, the fitting groove 626 can be engaged together with the transmission part 625, thereby enabling the transmission base 622 to rotate under the driving by the driving device 624.

In another embodiment of the present disclosure, with reference to FIGS. 34 and 36, the first abutting part 6261 and the second abutting part 6264 are ribs disposed on the inner wall of the transmission base 6221, and the first abutting part 6261 and the second abutting part 6264 enclose together to form a fitting groove 626. In this embodiment, the fitting groove 626 can rotate under the driving of the driving device 624 after being engaged and fitted with the transmission part 625.

In this embodiment, with reference to FIGS. 30, 32, and 37, when the roller brush 621 rotates forward under the driving of the transmission base 622, the first abutting part 6261 in the cooperating part cooperates with the transmission part 625, and the transmission part 625 drives the transmission base 622 to rotate forward under the driving of the driving device 624. During the forward rotation process, the transmission part 625 is driven by the output end 6241 of the driving device 624, and comes into contact with the first abutting part 6261. Upon contact, a first locking side is formed. The first locking side can prevent the first abutting part 6261 from moving away from the transmission part 625, thus preventing the transmission base 622 from loosening and disengaging from the driving device 624 in the axial direction of the roller brush 621, and improving the safety of the cleaning device.

Similarly, with reference to FIG. 38, when the roller brush 621 is rotating in reverse under the action of the transmission base 622, the second abutting part 6264 in the fitting portion is fitted with the transmission part 625, and the transmission part 625 drives the transmission base 622 to rotate in reverse under the driving of the driving device 624. During the reverse rotation, the transmission part 625 and the second abutting part 6264 contact with each other to form a second locking side, which can effectively prevent the second abutting part 6264 from moving away from the transmission part 625 during the reverse rotation. In this way, the roller brush 621 can achieve forward and reverse rotation through the first abutting part 6261 and the second abutting part 6264. During the rotation, the first locking side and the second locking side formed between the transmission part 625 and the fitting portion can effectively prevent the transmission base 622 from being disengaged from the driving device 624.

In one embodiment of the present disclosure, with reference to FIGS. 32 and 36, the transmission part 625 includes a first transmission part 6251 and a second transmission part 6252. The first transmission part 6251 is configured to be consistent with the extension direction of the first abutting part 6261 and cooperate with the first abutting part 6261, and the second transmission part 6252 is configured to be consistent with the extension direction of the second abutting part 6264 and cooperate with the second abutting part 6264.

In this embodiment, with reference to FIGS. 30 and 32, when the transmission part 625 is assembled with the first abutting part 6261 and the second abutting part 6264, the extension direction of the first abutting part 6261 is consistent with that of the first transmission part 6251, and the extension direction of the second abutting part 6264 is consistent with that of the second transmission part 6252, which facilitates the transmission part 625 to push the cooperating part to rotate under the driving of the driving device 624, and can effectively prevent loosening and disengagement between the two during the rotation of the cooperating part.

In one embodiment of the present disclosure, with reference to FIGS. 32 and 37, the first abutting part 6261 is configured to be inclined towards the direction of the force applied during forward rotation from one end adjacent to the driving device 624 to the other end away from the driving device 624. The second abutting part 6264 is configured to be inclined towards the direction of the force applied during reverse rotation from one end adjacent to the driving device 624 to the other end away from the driving device 624. Specifically, with reference to the view direction of FIG. 33, for example, the output end 6241 of the driving device 624 enters into the transmission base 6221 of the transmission base 622 from the bottom as shown in FIG. 33. The first abutting part 6261 is gradually inclined towards the direction of the force applied during forward rotation from its lower end to its upper end, that is, gradually inclined towards the left as shown in FIG. 33. In this way, During the first transmission part 6251 cooperates with the first abutting part 6261 and drives the first abutting part 6261 to rotate forward, the first abutting part 6261 has a tendency to move towards the driving device 624, so that the first abutting part 6261 and the first transmission part 6251 are locked during the forward rotation.

This is beneficial for the driving device 624 to drive the transmission base 622 to rotate by the first abutting part 6261. At the same time, they have the shapes and contours matched with each other, so that the area of the first locking side may be increased, which can more effectively prevent the transmission base 622 from loosening and being disengaged during rotation, thereby improving the safety of the cleaning device.

Based on the same principle, with reference to FIG. 38, the second abutting part 6264 gradually inclines towards the direction of the force applied during reverse rotation from its lower end to its upper end; in this way, during the second transmission part 6252 cooperate with the second abutting part 6264 to drive the second abutting part 6264 to rotate in reverse, the second abutting part 6264 has a tendency to move towards the driving device 624, so that the second abutting part 6264 and the second transmission part 6252 is locked during reverse rotation. The area of the second locking side may be thus increase, so as to prevent the axial looseness of the transmission base 622.

In an embodiment of the present disclosure, since the first abutting part 6261 and the second abutting part 6264 are configured to tilt along the direction of the force applied during forward and reverse rotation, with reference to FIG. 33, there is an angular difference between the first abutting part 6261 and the second abutting part 6264 in opposite directions. In this way, in practical using, the locking performance between the cooperating part and the transmission part 625 can be strengthened, and the probability of loosening or detachment of the transmission base 622 along its own axial direction may be decreased.

In one embodiment of the present disclosure, with reference to FIG. 33, the fitting groove 626 may be provided in plural and the plurality of fitting grooves 626 may be distributed in the circumferential direction of the transmission base 6221 and configured to extend along the axial direction of the transmission base 6221. The transmission part 625 may be provided in plural correspondingly, and the plurality of transmission parts 625 may be distributed in the circumferential direction of the output end 6241 of the driving device 624. In this embodiment, with reference to FIG. 32, the provision of a plurality of fitting grooves 626 enables the driving device 624 to simultaneously drive a plurality of transmission parts 625, and drive the transmission base 622 to rotate by a plurality of transmission parts 625, and the roller brush 621 is driven to rotate at last. The driving force applied by the output end 6241 of the driving device 624 to a single fitting groove 626 is dispersed somehow, so that the first abutting part 6261 and the second abutting part 6264 may be protected. This can effectively prevent excessive resistance between the roller brush 621 and the to-be-cleaned surface during the operation of the cleaning device, which may cause excessive force being applied to the first abutting part 6261 and the second abutting part 6264 during driving the transmission part 625 by the driving device 624, causing damage to the first abutting part 6261 and the second abutting part 6264. Preferably, the fitting grooves 626 and the transmission parts 625 are evenly distributed.

In one embodiment of the present disclosure, with reference to FIG. 32, the width of the fitting groove 626 is greater than or equal to the width of the transmission part 625. The transmission part 625 is configured to be detachably connected to the fitting groove 626 in a way of engagement. In practical using, when the width of the fitting groove 626 is greater than or equal to the width of the transmission part 625, the degree of freedom between the fitting groove 626 and the transmission part 625 is increased, which is beneficial for users to easily and conveniently insert the transmission part 625 into the fitting groove 626 to complete the assembly process when assembling the two parts. The situation that the interval between the first abutting part 6261 and the second abutting part 6264 is too small and thus the transmission part 625 is unable to be smoothly mounted can be avoided. The width of the fitting groove 626 in the present disclosure refers to the width of the narrowest position of the fitting groove 626, and the width of the transmission part 625 refers to the overall width of the transmission part 625. For example, when the transmission part 625 is in a shape of folded lines, the width of the transmission part 625 refers to the maximum lateral width between its endpoints and turning points.

In one embodiment of the present disclosure, the first abutting part 6261 and the second abutting part 6264 are offset in the axial direction of the transmission base 6221. With reference to the direction shown in FIG. 33, the first abutting part 6261 is disposed on the side of the transmission base 6221 closer to the driving device 624, and the second abutting part 6264 is disposed on the side of the transmission base 6221 away from the driving device 624.

In one embodiment of the present disclosure, with reference to FIG. 31, FIG. 32, and FIG. 36, the end of the first abutting part 6261 is provided with a first extending portion 6262 extending from the end of the first abutting part 6261 to the side away from the driving device 624, and the extending direction of the first extending portion 6262 is consistent with the extending direction of the second abutting part 6264. A first turning point 6263 is formed between the first abutting part 6261 and the first extending portion 6262.

In another embodiment of the present disclosure, with reference to FIGS. 32, 33, and 36, the end of the second abutting part 6264 is provided with an extended second extension portion 6265, which extends from the end of the second abutting part 6264 in a direction closer to the driving device 624, and the extension direction of the second extension portion 6265 is consistent with the extension direction of the first abutting part 6261. A second turning point 6266 is formed between the second abutting part 6264 and the second extension portion 6265.

In an embodiment of the present disclosure, with reference to FIG. 38, when the roller brush 621 rotates in reverse, the first extension 6262 has the same shape and function as the second abutting part 6264. The first extension 6262 is in contact with the other second transmission part 6252 and forms a locking side to prevent the disengagement of the cooperating part, so that the cooperating part and the transmission part 625 are locked together. Similarly, with reference to FIG. 37, when the roller brush 621 rotates forward, the second extension 6265 has the same shape and function as the first abutting part 6261, and it is in contact with the other first transmission part 6251, which can prevent the disengagement of the cooperating part, so that the cooperating part and the transmission part 625 are locked together.

In one embodiment of the present disclosure, the overall shape of the first abutting part 6261 and the first extending portion 6262 is the same as that of the second abutting part 6264 and the second extending portion 6265. With reference to FIG. 32, the fitting groove 626 formed by the side walls of the first abutting part 6261 and the second abutting part 6264, and the first transmission part 6251 and the second transmission part 6252 that cooperate with the fitting groove 626 also have the same shapes. Such arrangement can simplify the assembly between the fitting groove 626 and the transmission part 625. The user only needs to align any one of the fitting groove 626 and the transmission part 625 that cooperate with each other to complete the engagement of all the fitting grooves 626 and the transmission parts 625. The engagement between the fitting groove 626 and the transmission part 625 may be done by simple connections, so that the user's experience may be improved.

At the same time, when the first transmission part 6251 and the first abutting part 6261 are combined together, the position of the turning point between the first transmission part 6251 and the second transmission part 6252 is fitted with the first turning point 6263 between the first abutting part 6261 and the first extending part 6262, so that the stability may be improved during forward rotation, and the transmission part may be thus locked with the first abutting part 6261 and the first extending part 6262. Similarly, when the second transmission part 6252 and the second abutting part 6264 are combined together, the position of the turning point between the first transmission part 6251 and the second transmission part 6252 is fitted with the second turning point 6266 between the second abutting part 6264 and the second extending part 6265, so that the stability may be improved during the reverse rotation, and the transmission part may be thus locked with the second abutting part 6264 and the second extending part 6265.

In addition, the overall shape of the first abutting part 6261 and the first extending portion 6262 is the same as that of the second abutting part 6264 and the second extending portion 6265. Alternatively, the second abutting part 6264 can be formed as the first extending portion 6262, and the first abutting part 6261 can be formed as the second extending portion 6265, which is also beneficial for processing and preparation. The production cost may be significantly reduced by using same structure for components, compared to using irregular structure, which is beneficial for production and manufacturing.

With reference to the view direction of FIG. 36, in this embodiment, the cooperating part and the transmission part 625 are configured in a “V” shape structure, that is, the first abutting part 6261 and the first extending part 6262 are configured to be gradually inclined upward from their turning point. Similarly, the second abutting part 6264 and the second extending part 6265 also have the same structure as the first abutting part 6261 and the first extending part 6262. The first transmission part 6251 and the second transmission part 6252 are provided to be gradually inclined upward from their turning point.

FIGS. 39 to 41 are simplified schematic diagrams of the motion relationship between the transmission part 625 and the cooperating part in the cleaning device of the present disclosure. The left side of FIGS. 39 to 41 is the side of the roller brush driving device, and the right side of FIGS. 39 to 41 is the side where the roller brush is mounted. The roller brush can be mounted or removed from this side, and along the detachment direction DE of the roller brush in FIGS. 39 to 41, the roller brush can be removed from the floor brush of the cleaning device. When the transmission part 625 drives the cooperating part to move upward as shown in the figure, i.e., the transmission part 625 drives the cooperating part to rotate clockwise (reverse rotation) according to the view shown in FIG. 27. When the transmission part 625 drives the cooperating part to move downward as shown in the figure, i.e., the transmission part 625 drives the cooperating part to rotate counterclockwise (forward rotation) according to the view shown in FIG. 27. In the present embodiment, the cooperation relationship between the transmission part 625 and the cooperating part has been described in detail above. The difference is that, with reference to the view direction of FIG. 39, in the present embodiment, the cooperating part and the transmission part 625 are constructed in a “A” shape structure, i.e., the first abutting part 6261 and the first extending part 6262 are provided as extending downward while being gradually inclined from the connection point. Similarly, the transmission part, the second abutting part 6264, and the second extending part 6265 also have the same structure as the first abutting part 6261 and the first extending part 6262.

In one embodiment of the present disclosure, with reference to the view direction of FIG. 39, when the transmission part 625 drives the cooperating part to rotate counterclockwise, i.e., to rotate forward, with reference to FIG. 40, the first abutting part 6261 of the cooperating part and the first transmission part 6251 of the transmission part 625 are fitted together to form a first locking side therebetween. The cooperation relationship between the transmission part 625 and the cooperating part has been described in detail above, and repeated description would be omitted to avoid redundancy.

In another embodiment of the present disclosure, when the transmission part 625 rotates clockwise with the cooperating part under the driving of the driving device 624, i.e., when it rotates in reverse, with reference to FIG. 41, the second abutting part 6264 of the cooperating part is in contact with the second transmission part 6252 of the transmission part 625 to form a second locking side therebetween. The cooperation relationship between the transmission part 625 and the cooperating part has been described in detail above, and repeated description would be omitted to avoid redundancy.

It should be noted that whether the transmission part 625 and the cooperating part are in a “∨” or “∧” structure can be selected and designed by those skilled in the art as needed, and no limitation would be applied thereto in the present disclosure.

In one embodiment of the present disclosure, with reference to FIG. 32 and FIG. 33, the first abutting part 6261 and the first extending portion 6262 are in V-shape as a whole, and the second abutting part 6264 and the second extending portion 6265 are in V-shape as a whole.

In another embodiment of the present disclosure, the first abutting part 6261 and the first extending portion 6262 are both in the shape of a circular arc, and the second abutting part 6264 and the second extending portion 6265 are both in the shape of a circular arc.

In one embodiment of the present disclosure, in order to further simplify the structure among the first abutting part 6261, the first extending portion 6262, the second abutting part 6264, and the second extending portion 6265, the present embodiment may only keep the first abutting part 6261 and the second abutting part 6264. As long as the first abutting part 6261 can cooperate with the transmission part 625 to rotate forward and the second abutting part 6264 can cooperate with the transmission part 625 to rotate in reverse under the driving of the driving device 624, no limitation would be applied thereto in the present disclosure.

In one embodiment of the present disclosure, with reference to FIG. 35, the roller brush assembly 62 further includes a control unit 627. The control unit 627 is configured to control the driving device 624 to rotate forward for a first period, and to control the driving device 624 to rotate in reverse for a second period.

In practical using, the control unit can be communicatively connected to the driving device 624, and the control unit is configured to issue control signals to the driving device 624, so as to control the driving device 624 to switch of the rotation direction of the roller brush 621. Since the first direction is opposite to the second direction, the rotation direction of the roller brush 621 can be changed during the cleaning operation of the cleaning device 6. The damage to the structure of the roller brush 621 due to long-term rotation in a single direction may be avoided, and thus the roller brush 621 may be protected and the interference between the roller brush 621 and the to-be-cleaned surface can always be maintained within a relatively stable range. This effectively improves the cleaning effect and service life of the roller brush 621.

Embodiment 2

The second embodiment is same as the first embodiment except that the transmission part is provided on the transmission base 622. The output end 6241 of the driving device 624 has a transmission cavity, and the cooperating part is a fitting groove provided on the transmission cavity. The first abutting part and the second abutting part are groove walls on the opposite sides of the fitting groove. Alternatively, the first abutting part and the second abutting part are ribs provided on the inner wall of the transmission cavity, and the first abutting part and the second abutting part enclose to form a fitting groove. Specifically, the specific arrangement between the transmission part, the fitting groove, the first abutting part, and the second abutting part is the same as that in the first embodiment, and those skilled in the art can fully implement the arrangement based on the description in the first embodiment, and repeated description is omitted here to avoid abundancy.

In one embodiment of the present disclosure, a roller brush assembly 62 is further provided. The roller brush assembly 62 includes a roller brush 621 and a driving device 624. The roller brush 621 has a roller brush cavity 6211 extending in its axial direction, and a transmission base 622 is disposed in the roller brush cavity 6211. The output end 6241 of the driving device 624 extends into the roller brush cavity 6211 and is detachably connected to the transmission base 622 to drive the roller brush 621 to perform rotation.

A transmission mechanism is provided between the transmission base 622 and the output end 6241 of the driving device 624, and the transmission mechanism includes a transmission part 625 and a cooperating part that are engaged and fitted together. The transmission part 625 is configured to be locked with the cooperating part in driving the cooperating part to perform forward and reverse rotation.

The structure and connection relationship of the roller brush assembly in this embodiment are exactly the same as those of the roller brush assembly 62 described above, and its connection method for engagement with the cleaning device in using is also exactly the same as those of the roller brush assembly 62 described above. Those skilled in the art can derive the structure of and the way of using the roller brush assembly in this embodiment directly based on the description above, and therefore no further detailed explanation is provided here.

In one embodiment of the present disclosure, a roller brush assembly is further provided and includes a roller brush 621 and a driving device 624. The roller brush 621 has a roller brush cavity 6211 extending in its axial direction, and a transmission base 622 is provided in the roller brush cavity 6211. The output end 6241 of the driving device 624 extends into the roller brush cavity 6211 and is detachably connected to the transmission base 622 to drive the roller brush 621 to perform rotation. A transmission mechanism is provided between the transmission base 622 and the output end 6241 of the driving device 624, and the transmission mechanism includes a transmission part 625 and a cooperating part, both of which are in the shape of V or arc and are engaged and fitted together. The transmission part 625 is configured to be locked together with the cooperating part in driving the cooperating part to rotate forward and in reverse.

The structure and principle of the transmission part 625 and the cooperating part in this embodiment are the same as those in the above embodiment, and repeated description is omitted here to avoid abundancy.

The technical solutions adopted by the cleaning device in the present disclosure are explained below in conjunction with specific application scenarios to facilitate understanding. In the following application scenarios, the cleaning device is described as a handheld scrubber.

Application Scenario 1

When a user pushes the handheld scrubber to clean the to-be-cleaned surface, the user can move the holding part of the surface wet cleaner on the ground and use the roller brush assembly 62 to clean the to-be-cleaned surface. With reference to FIG. 28 and FIG. 31, one end of the transmission base 6221 in the roller brush assembly 62 is sleeved on the driving device 624, so that the output end 6241 of the driving device 624 is connected with the transmission base 622 in the roller brush cavity 6211. With driving by the driving device 624, the output end 6241 drives the transmission base 622 to rotate. The transmission base 622 is connected with the inner wall of the roller brush 621, and may drive the roller brush 621 to rotate during the rotation of the transmission base 622.

With reference to FIG. 35, under the control of the control unit 627, the output end of the driving device 624 drives the transmission base 622 to rotate the roller brush 621 forward or in reverse. In practical using, with reference to FIG. 32, the first abutting part 6261 drives the drive transmission base 622 to rotate forward under the action of the output end 6241 of the driving device 624. During the rotation, a surface of the first abutting part 6261 in the cooperating part makes contact with the transmission part 625 to form a first locking side. The first locking side has the same shape as the first abutting part 6261, so that the drive transmission base 622 is effectively prevented from loosening and being disengaged from the driving device 624 in the axial direction based on the first locking side.

Similarly, with the action of the output end 6241 of the driving device 624, the transmission base 622 can drive the roller brush 621 to rotate reversely. During the rotation, the surface the second abutting part 6264 contacting the transmission part 625 forms a second locking side. The second locking side can also prevent the transmission base 622 from loosening and being disengaged from the driving device 624 during rotation.

In this way, the direction of rotation of the roller brush 621 may be changed by the driving device 624, so that the bristles on the roller brush 621 may not remain in the same direction for a long time but always remain in a fluffy state, and thus the roller brush 621 can be protected and the cleaning power of the roller brush 621 may be increased. At the same time, the first locking side and the second locking side have the same structure as the first abutting part 6261 and the second abutting part 6264, it is further possible to effectively avoid the loosening and separation of the transmission base 622 from the driving device 624 in the axial direction of the roller brush 621, and thus the safety in using the cleaning device may be improved.

Application Scenario 2

When the roller brush 621 wears out or has malfunctions due to being used for a long time, it needs to be replaced. The width of the fitting groove 626 of the present disclosure is greater than or equal to the width of the transmission part 625, and the transmission part 625 is configured to be detachably connected to the fitting groove 626 by engaging. Therefore, during disassembling the roller brush 621, the first locking side and the second locking side may not prevent the transmission base 622 from moving away from the driving device 624 since there is some freedom between the fitting groove 626 and the transmission part 625. The user can simply and easily disassemble driving device 624 from the transmission base 622 by rotating the driving device 624.

Similarly, during the assembly of the roller brush 621, the user simply aligns the transmission part 625 with the fitting groove 626, and rotates it in the circumferential direction of the roller brush 621 after insertion, the driving device 624 and the transmission base 622 are locked together to complete the assembly after a first locking side is formed between the first abutting part 6261 and the first transmission part 6251, or a second locking side is formed between the second abutting part 6264 and the second transmission part 6252. This solves the problem of there is difficulty in disassembly and assembly the roller brush 621 from the driving device 624, and user's experience is thus degraded. With a simple and quick disassembly method, the user's experience may be improved.

It should be noted that the cleaning device of the present disclosure can be applied not only to the above-mentioned handheld surface wet cleaner, but also to other devices that require a roller brush assembly to achieve cleaning of the to-be-cleaned surface, such as surface wet cleaner robot, sweeping-scrubber device, etc. Detailed examples may be not listed in the present disclosure.

With reference to FIG. 42a to FIG. 55. When traditional surface wet cleaner is used, the noise is very loud, and user's experience is thus degraded. It is because the demand for cleanness and tidiness of the ground achieved by the cleaning device increases, and thus high-power suction motors are used in surface wet cleaners. High-power suction motors have high rotation speed and powerful suction, which leads to better tidiness after cleaning operation. However, the problem in using high-power suction motors is that the high-speed rotation of fan blades of the motor brings high-frequency noise, which generates large noise and degrades user's experience.

In view of the above problems, the embodiments of the present disclosure provide a cleaning device and a power source device that solve the above problems, so as to reduce the noise generated by the cleaning device in using.

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope as claimed by the present disclosure.

FIGS. 42a and 41b are structural schematic diagrams of the cleaning device provided by the embodiments of the present disclosure, FIG. 43 is a structural schematic diagram of the cross-section of the power source device provided by the embodiments of the present disclosure, and FIG. 44 is a structural schematic diagram of the partial cross-section of the power source device provided by the embodiments of the present disclosure, as shown in FIGS. 1a to 44.

In one embodiment of the present disclosure, a cleaning device is provided and include a main body 10 and a power source device 700 disposed on the main body 10. The main body 10 provides a supporting body for the assembly of the power source device 700, and the power source device 700 provides suction force for the cleaning device when the cleaning device is used, and is configured to suck sewage from the to-be-cleaned surface to clean the to-be-cleaned surface.

The power source device 700 can be fixedly mounted on the main body 10. Alternatively, as shown in FIG. 42b, the power source device 700 can be detachably mounted on the main body 10. For example, the power source device 700 can be removed from the main body 10 and assembled with other equipment or devices. For example, the power source device 700 can be removed from the main body 10 of the surface wet cleaner shown in FIG. 42a and mounted on a small handheld vacuum cleaner. The user can then hold the small handheld vacuum cleaner to clean areas that cannot be cleaned by the surface wet cleaner. Alternatively, the power source device 700 can be mounted on a car vacuum cleaner for cleaning the vehicle, etc. There is no limitation on the using of the power source device in the present embodiment.

With reference to FIG. 43 and FIG. 44, the power source device 700 includes a power source shell 71 and a motor assembly 72. The power source shell 71 has a first receiving cavity 711. The motor assembly 72 is disposed in the first receiving cavity 711 and has an air outlet path 712 between the motor assembly 72 and the inner wall of the first receiving cavity 711. The motor assembly 72 includes a motor 721 and a muffler cover 722. The motor 721 has an air inlet path 7211 inside, and the muffler cover 722 is buckled on the periphery of the motor 721. The inner wall of the muffler cover 722 and the motor 721 form a airflow path for air flow circulation. The airflow entering the air inlet path 7211 passes through the airflow path between the muffler cover and the motor, passes through the muffler cover 722, and enters the air outlet path 712 to be discharged.

With reference to FIG. 44, the arrows in FIG. 44 indicate the flow path of airflow. When the motor 721 is working, external air is sucked into the air inlet path 7211 inside the motor 721 through the inlet. Then, the airflow enters the airflow path between the muffler cover 722 and the motor 721 through the air inlet path 7211. Guiding holes evenly provided on the muffler cover 722 act on the airflow to force the airflow to bypass the muffler cover 722 and pass the side of the muffler cover 722 away from the air inlet path 7211. Taking the orientation in FIG. 44 as an example, the airflow in the airflow path between the muffler cover 722 and the motor 721 enters the air outlet path through the guiding holes on the muffler cover 722. Due to the existence of the muffler cover 722, the flow path of airflow becomes longer. Finally, the airflow in the airflow path between the muffler cover 722 and the motor 721 flows out through the guiding holes 722a to enter the air outlet path 712, and then flows out of the power source device 700 through the air outlet holes 7121 of the air outlet path 712. The existence of the muffler cover 722 also lengthens the path for airflow to flow out of the power source device. It can be seen that the existence of the muffler cover 722 lengthens the flow path of airflow, and at the same time, the airflow is adjusted through the guiding holes 722a on the muffler cover 722, which can effectively reduce high-frequency wind noise and reduce noise of cleaning device. In particular, high-frequency wind noise caused by the high-speed rotation of the fan blades of the motor 721 can be reduced, thereby bringing a good user experience.

In the embodiments of the present disclosure, cleaning device includes, but not limited to, a handheld cleaning device, standing cleaning device, cleaning robots, etc. The cleaning devices described in the above embodiments and the following embodiments are described with the cleaning device shown in FIG. 42a as an example. It should be noted that the illustration of the cleaning device shown in FIG. 42a is only an example, and does not constitute an unnecessary limitation on the embodiments of the present disclosure.

With reference to FIG. 42a, a handheld cleaning machine is shown in FIG. 42a. The handheld cleaning machine includes a main body 10, one end of which is provided with a handle 11 for the user to hold, and the other end is provided with a floor brush assembly 12. The main body 10 is further provided with a power source device 700 and a main control unit. The main control unit is configured to control the power source device 700 and the floor brush assembly 12 and other assemblies to cooperate with each other to perform cleaning. In some embodiments, the main body 10 is further provided with a clear water tank 13 and a sewage tank 14. The clear water tank 13 can provide cleaning water to the floor brush assembly 12 for cleaning the floor. The sewage can be sucked into the sewage tank 14 through the floor brush assembly 12. The inlet of the sewage tank 14 is communicated with the floor brush assembly 12, and the outlet of the sewage tank 14 is communicated with the air inlet hole of the power source device 700. When the power source device 700 works, it generates negative pressure to provide power for the suction of the cleaning machine, so that the sewage can be sucked into the sewage tank 14 with the airflow and the sewage and airflow may be separated in the sewage tank 14. The sewage accumulates in the sewage tank 14, and the air flows out of the sewage tank 14 through the air outlet hole of the sewage tank 14.

With reference to FIG. 45, in connection with FIG. 43 and FIG. 44, in some embodiments of the present disclosure, the muffler cover 722 may be implemented to include a connecting section 7222 close to the air inlet path 7211 and a guiding section 7223 away from the air inlet path 7211. According to the orientation of FIG. 43 and FIG. 44, the connecting section 7222 is located above the guiding section 7223. The guiding section 7223 is provided with air guiding holes 722a. The connecting section 7222 may or may not be provided with air guiding holes 722a. If the connecting section 7222 is not provided with air guiding holes 722a, the air flow passing through the connecting section 7222 is guided to guiding section 7223 farther away, which lengthens the air flow path, thereby effectively extending the flow path of the air inlet path 7211. Of course, the connecting section 7222 may be provided with air guiding holes 722a. When the connecting section 7222 is provided with air guiding holes 722a, the number and/or diameter of the air guiding holes 722a on the connecting section 7222 may be smaller than those on the guiding section 7223, but the number and/or diameter of the air guiding holes 722a on the connecting section 7222 may be the same as those on the guiding section 7223. Alternatively, the number and/or diameter of the air guiding holes 722a gradually increase along the direction from the connecting section 7222 to the guiding section 7223.

With reference to FIG. 45, in connection with FIG. 43 and FIG. 44, in some embodiments of the present disclosure, the motor 721 includes, but not limited to, a brushless suction motor 721. The motor 721 may be implemented to include a main body section and a suction section along the axial direction of the motor 721. The main body section provides a supporting part for assembly of the suction section and provides power. The suction section includes components such as an impeller and a wheel cover. The impeller may rotate by the power output from the main body section to generate suction. The impeller may rotate by the main body section, to generate a suction force, to force external air to enter the air inlet path 7211 through the air opening. The main body section can be entirely provided on one side of the suction section, or a part of the main body section can extend into the wheel cover of the suction section.

According to different needs, the muffler cover 722 can be buckled at least on the periphery of the main body section, i.e., the muffler cover 722 can be buckled on the periphery of the main body section. Alternatively, the muffler cover 722 can be buckled on the periphery of the main body section, and a part of the muffler cover 722 can be buckled on the suction section. There is a second air path 7224 between the outer wall of the muffler cover 722 and the inner wall of the first accommodation chamber 711, and the second air path 7224 and the first air path 7214 form an air outlet path 712.

Further, the muffler cover 722 is located at least partially above the outlet of the air inlet path 7211. With reference to FIG. 46, in some embodiments of the present disclosure, the motor 721 has a separation line 7215 along the radial direction of the motor 721, which divides the motor 721 into a main body section and a suction section. First implementation of muffler cover 722 may be that the outlet 721a of the air inlet path 7211 and the muffler cover 722 are both located on one side of the separation line 7215. As shown in FIG. 46, the outlet 721a of the air inlet path 7211 and the muffler cover 722 are both located on the upper side of the separation line 7215.

A second implementation of the muffler cover 722 may be that the outlet 721a of the air inlet path 7211 and the lowermost air guiding hole 722a of the muffler cover 722 are located on two sides of the separation line 7215, so that the air flowing out of the outlet 721a of the air inlet path 7211 flows upward through the muffler cover 722, an extension path may be formed by the gap between the muffler cover 722 and the motor 721. The extension path extends the flow path of the air path.

A third implementation of the muffler cover 722 is that, along the radial direction of the motor 721, the muffler cover 722 has a center line 7225, and the outlet 721a of the air inlet path 7211 and the center line 7225 of the muffler cover 722 are located on two sides of the separation line 7215. This implementation allows more than half of the muffler cover 722 to be located on one side (or above) of the outlet of the air inlet path 7211.

The examples corresponding to the second and third implementations described above are not shown in the drawings of the description.

In order to better extend the air outlet path 712 to effectively reduce high-frequency wind noise, in some embodiments of the present disclosure, an air opening of the first air path 7214 away from the second air path 7224 is the air outlet hole 7121 of the air outlet path 712. In this way, taking the orientation of FIG. 43 and FIG. 44 as an example, the air outlet hole 7121 of the air outlet path 712 can be located below the muffler cover 722. When the airflow flows in the air outlet path 712, it needs to pass through the second air path 7224 first and then through the first air path 7214, so that the airflow can flow longer to reduce high-frequency wind noise. In some embodiments, the air outlet hole 7121 of the air outlet path 712 is located on the side of the power source shell 71; or the air outlet hole 7121 of the air outlet path 712 is located on the end surface of the power source shell 71 where the air inlet hole of the air inlet path 7211 is provided. With the above-mentioned way for providing the air outlet hole 7121, airflow backflow may effectively prevented. Even if the discharged airflow carries vapor, the condensed water may not flow back to the motor 721, the safety of the entire machine may be effectively improved. The air outlet hole 7121 of the air outlet path 712 can be provided around the air inlet hole of the air inlet path 7211, and the air outlet hole 7121 is located outside the air inlet hole, so that the air outlet hole 7121 has a large air outlet area and even airflow, ensuring the circulation efficiency of air flow.

As shown in FIG. 45, in some embodiments of the present disclosure, the muffler cover 722 may be implemented to in a barrel structure, and the barrel bottom of the barrel structure has connecting holes 7226. With reference to FIG. 47 and FIG. 48, one end of the axial direction of the motor 721 is sleeved with a shock-absorbing pad 723. With reference to FIG. 49, the muffler cover 722 is connected to the shock-absorbing pad 723 through the connecting holes 7226, and the barrel wall of the muffler cover 722 surrounds the periphery of the motor 721. The shock-absorbing pad 723 can be sleeved on an end of the main body section of the motor 721 away from the suction section, and the periphery of the shock-absorbing pad 723 has a flange, with which the shock-absorbing pad 723 can be wrapped around part of the main body section. The connection between the muffler cover 722 and the motor 721 be achieved by the shock-absorbing pad 723, and the motor assembly 72 can be abutted against the cavity wall of the first receiving cavity 711 by the shock-absorbing pad 723. For example, the motor assembly 72 can be abutted against the cavity wall of the first receiving cavity 711 by using the shock-absorbing pad 723. The sealing and shock isolation between the motor 721 and the muffler cover 722 can be achieved by the shock-absorbing pad 723, and the shock isolation and sealing between the motor assembly 72 and the power source shell 71 can be achieved by the shock-absorbing pad 723, so that the noise caused by vibration may be reduced. During assembly, the shock-absorbing pad 723 can be pre-sleeved on the motor 721, and then the motor 721 with the shock-absorbing pad 723 mounted can be fitted into the muffler cover 722, or the shock-absorbing pad 723 can be mounted on the muffler cover 722 first, and then the motor 721 can be fitted onto the shock-absorbing pad 723.

Further, to avoid the rotation of the main body section 7212 caused by the rotation of the impeller of the motor 721, in some embodiments of the present disclosure, with reference to FIGS. 47 to 49, the connecting holes 7226 may be polygonal holes, including but not limited to triangular holes, rectangular holes, pentagonal holes, hexagonal holes and other non-rotatable round holes. The shock-absorbing pad 723 is provided with a polygonal boss 7231 used in conjunction with the connecting holes 7226, and the connecting holes 7226 are connected with the polygonal boss 7231. By using the polygonal boss 7231 in conjunction with the polygonal hole, the rotation of the main body section 7212 of the motor 721 along the circumferential direction can be restricted, and the rotation of the main body section 7212 caused by the rotation of the impeller of the motor 721 may be prevented.

In order to enable the airflow to flow as guided by the air path, in some embodiments of the present disclosure, in connection with FIG. 49, the end of the motor 721 away from the shock-absorbing pad 723 is sleeved with an inlet sealing sleeve 724. One end of the inlet sealing sleeve 724 is in abutted against the barrel opening of the muffler cover 722 to seal the gap between the barrel opening of the muffler cover 722 and the motor 721. The other end of the inlet sealing sleeve 724 is abutted against the power source shell 71 to isolate the inlet of the air inlet path 7211 from the air outlet holes 7121 of the air outlet path 712, to seal the gap between the air inlet holes of the air inlet path 7211 and the air outlet holes 7121 of the air outlet path 712. The inlet sealing sleeve 724 can be fitted on the suction section of the motor 721, and the inlet sealing sleeve 724 can be adapted to the outer contour of the suction section 7213. The inlet sealing sleeve 724 can effectively isolate the air inlet path 7211 from the air outlet path 712, ensuring that the airflow in the air inlet path 7211 can smoothly enter the path between the motor and the muffler cover, and then enter the air outlet path 712 through the air guiding holes on the muffler cover, so that the flow direction of the airflow can be ensured and the airflow may flow through a longer path, so as to reduce high-frequency wind noise. At the same time, the inlet sealing sleeve 724 is used for sealing, and the inlet sealing sleeve 724 can further absorb shock between the motor 721 and the power source shell 71, and absorb shock between the motor 721 and the muffler cover 722, to reduce the noise caused by vibration.

With reference to FIG. 49 and FIG. 50, in some embodiments of the present disclosure, the motor assembly 72 and the power source shell 71 may be connected in a way that the barrel wall of the muffler cover 722 is provided with a first snap-fit structure 7227, and the power source shell 71 is provided with a second snap-fit structure 713 that is used in conjunction with the first snap-fit structure 7227. The muffler cover 722 is connected to the second snap-fit structure 713 by the first snap-fit structure 7227. Such snap-fit connection may facilitate the connection between the motor assembly 72 and the power source shell 71, and assembly and disassembly may be completed quickly and the disassembly and assembly time may be greatly saved. At the same time, the snap-fit structure may further be used for positioning, to ensure the motor assembly 72 to be accurately mounted with the power source shell 71, so as to more smoothly complete the suction operation.

With reference to FIG. 44, in some embodiments of the present disclosure, the power source shell 71 may be provided in a way that the power source shell 71 includes an upper cover of shell 71a and a lower cover of shell 71b. The upper cover of shell 71a has a first receiving slot, and the lower cover of shell 71b has a second receiving slot. The upper cover of shell 71a is connected to the lower cover of shell 71b, so that the first receiving slot and the second receiving slot form a first receiving cavity 711. The lower cover of shell 71b is connected to the motor assembly 72, and the lower cover of shell 71b has an opening that is connected to the air inlet path 7211. The air outlet hole 7121 of the air outlet path 712 is disposed on the lower cover of shell 71b. The upper cover of shell 71a and the lower cover of shell 71b can be separated from each other to facilitate the assembly of the motor assembly 72. For example, the motor assembly 72 can be assembled in the second receiving slot of the lower cover of shell 71b first. If the lower cover of shell 71b is provided with a second snap-fit structure 713, the second snap-fit structure 713 is connected to the first snap-fit structure 7227 on the muffler cover 722 to assemble the motor assembly 72 in the second receiving slot of the lower cover of shell 71b. Then, the lower cover of shell 71b assembled with the motor assembly 72 is connected to the upper cover of shell 71a, and the motor assembly 72 is assembled into the first receiving slot.

For example, one assembly way may be as follows:

First, with reference to FIG. 47 and FIG. 48, the shock-absorbing pad and the inlet sealing sleeve 724 are first placed on the opposite ends of the motor 721. For example, the shock-absorbing pad 723 is placed on one end of the main body section, and the inlet sealing sleeve 724 is placed on the suction section.

After that, with reference to FIG. 49, the motor 721 assembled with a shock-absorbing pad and an inlet sealing sleeve 724 is mounted into the muffler cover 722 to form a motor assembly 72.

Then, with reference to FIG. 50, the motor assembly 72 is assembled onto the lower cover of shell 71b by connecting the first snap-fit structure 7227 on the sound-absorbing cover 722 with the second snap-fit structure 713 on the lower cover of shell 71b.

Finally, with reference to FIG. 44, the lower cover of shell 71b assembled with the motor assembly 72 is mounted into the upper cover of shell 71a and fixed with screws, to form the power source device 700.

After assembly, there is a second air path 7224 between the muffler cover 722 and the upper cover of shell 71a, and there is a first air path 7214 between the inlet sealing sleeve 724 and the lower cover of shell 71b. The air guiding hole of the muffler cover 722 is located above the outlet of the air inlet path 7211, and the air outlet hole 7121 is located below the muffler cover 722. The vibration isolation and sealing between the motor 721 and the lower cover of shell 71b can be achieved by using the inlet sealing sleeve 724, and the vibration isolation and sealing between the motor 721 and the muffler cover 722 can be achieved by using the inlet sealing sleeve 724 and the shock-absorbing pad 723. The vibration isolation and sealing between the motor assembly 72 and the upper cover of shell 71a can be achieved by using the shock-absorbing pad 723.

The air flow path after assembly is as follows, with reference to FIG. 44 and FIG. 46.

The arrows in FIG. 44 and FIG. 46 indicate the flow path of airflow:

When the motor 721 is working, the external air enters the air inlet path 7211 through the opening on the lower cover of shell 71b. Then, the airflow enters the air path between the muffler cover and the motor through the air inlet path 7211, so that the flow path of the airflow may be extended. At the same time, the air guiding holes 722a evenly provided on the muffler cover 722 are configured to adjust the airflow, forcing the airflow to bypass the muffler cover 722 and pass through the side of the muffler cover 722 away from the air inlet path 7211, that is, the airflow enters the air outlet path through the guiding holes of the muffler cover 722.

Then, the airflow coming out of the air guiding hole enters the second air path 7224 between the muffler cover 722 and the upper cover of shell 71a, flows through the second air path 7224 into the first air path 7214 between the inlet sealing sleeve 724 and the lower cover of shell 71b, and finally flows out of the power source device 700 through the air outlet holes 7121 provided on the lower cover of shell 71b.

With reference to FIG. 43, in some embodiments of the present disclosure, the power source shell 71 has a second receiving cavity 714 on the side away from the motor 721 along the axial direction of the motor 721. The second receiving cavity 714 is provided with a battery pack assembly 73, which is electrically connected to the motor 721. Taking the orientation in FIG. 43 as an example, the battery pack assembly 73 is provided above the motor assembly 72, to make space for the muffler cover 722 to be placed above the outlet of the air inlet path 7211, or at least make the center point of the muffler cover 722 be above the outlet of the air inlet path 7211, so as to extend the air inlet path 7211 and correspondingly lengthen the air outlet path 712, so that high-frequency wind noise may be reduced. The cable of the motor 721 can extend out of the first receiving cavity and into the second receiving cavity to be connected with the battery pack assembly 73. The through hole between the first receiving cavity and the second receiving cavity can be sealed by a shock-absorbing pad 723 to prevent airflow from entering the second receiving cavity.

Further, a heat dissipation air path is provided between the first receiving cavity and the second receiving cavity, which can be connected to the air path between the motor and the muffler cover and the air outlet path 712. The airflow can enter the second receiving cavity through the heat dissipation air path, flow through the battery pack assembly 73 to dissipate heat from the battery pack assembly 73, and then flow out through the air outlet path 712 after heat exchange.

With reference to FIG. 43 and FIG. 51, in some embodiments of the present disclosure, a display assembly 74 is provided at the end of the power source shell 71 away from the motor 721 along the axial direction of the motor 721. The display assembly 74 can be configured to display corresponding information of the cleaning device. The display assembly 74 may be provided in a way that the display assembly 74 includes a main body 741 and a display screen 742 disposed at one end of the main body 741 in the axial direction. A sealing ring groove 7411 is provided circumferentially on the side of the main body 741, and a mounting part 7412 is also provided on the side of the main body 741. The display screen 742 and the mounting part 7412 are disposed on respective sides of the sealing ring groove 7411 in the axial direction. The display assembly 74 is connected to the power source shell 71 through the mounting part 7412.

The display assembly 74 may be connected to the upper cover of shell 71a via the mounting part 7412. The display assembly 74 can be further connected to the battery pack assembly 73, which provides power to the display assembly 74. A sealing ring 7412 can be placed in the sealing ring groove 7411. During assembly, the sealing ring 7412 is located between the display screen 742 and the mounting part 7412, to prevent substances such as water from entering the power source device 700 and the display assembly 74 through the gap between the display assembly 74 and the power source shell 71, which may damage the electrical components inside the power source device 700 and the display assembly 74. At the same time, the overall modularization of the display assembly 74 is achieved by integrating the display screen 742 on the main body 741 and assembling the display assembly 74 by the mounting part 7412 on the main body 741, so that the problems of a large number of parts, a dispersed distribution, and a large number of gaps may be avoided.

With reference to FIG. 51, in some embodiments of the present disclosure, the mounting part 7412 may be implemented in a way that the mounting part 7412 includes an introduction slot 741a extending in the axial direction of the main body 741, a positioning slot 741b extending in the circumferential direction of the main body 741 and communicating with the introduction slot 741a, and a first locking hole 741c. One end of the power source shell 71 is provided with a mounting slot 715, and the inner wall of the mounting slot 715 is provided with a mounting protrusion to be used with the introduction slot 741a and the positioning slot 741b, as well as a second locking hole to be used with the first locking hole 741c. During assembly, the main body 741 of the display assembly 74 extends into the mounting slot 715, and the mounting protrusion first enters the introduction slot 741a along the axial direction of the main body 741, when the mounting protrusion moves to the bottom of the introduction slot 741a, i.e., to the connection between the introduction slot 741a and the positioning slot 741b, the display assembly 74 is then rotated so that the mounting protrusion enters the positioning slot 741b, and the display assembly 74 is further rotated till the bottom of the positioning slot 741b. Finally, the first locking hole 741c and the second locking hole are connected by screws or other fasteners to prevent the display assembly 74 from being rotated relative to the power source shell 71. At the same time, the sealing ring in the sealing ring slot 7411 is compressed by the groove wall of the mounting slot 715, to seal the gap between the mounting slot 715 and the main body 741, and prevent the entry of moisture and other substances. The connection method is simple, convenient for assembly and disassembly, and can be repeatedly used for multiple times to avoid the situation where the display assembly 74 cannot be restored after removal.

Based on the above embodiments, with reference to FIGS. 43 to 51, the embodiments of the present disclosure further provide a power source device 700, which includes a power source shell 71 and a motor assembly 72. The power source shell 71 has a first receiving cavity 711. The motor assembly 72 is disposed in the first receiving cavity 711 and has an air outlet path 712 between the motor assembly 72 and the inner wall of the first receiving cavity 711. The motor assembly 72 includes a motor 721 and a muffler cover 722. The motor 721 has an air inlet path 7211 inside, and the muffler cover 722 is buckled on the periphery of the motor 721. There is an extension path 7221 between the inner wall of the muffler cover 722 and the motor 721, which extends the flow path of the air inlet path 7211. The airflow entering the air inlet path 7211 passes through the extension path 7221 before entering the air outlet path 712 to be discharged.

It should be noted that the implementation of the power source device 700 can refer to the implementations described in the above embodiments, provided that there is no conflicts in the structures. The power source device 700 is the same as the one described in the above embodiments, and detailed description is omitted to avoid abundancy.

The technical solutions adopted in the present disclosure are explained below in conjunction with specific application scenarios to facilitate understanding.

Application Scenario 1

The user cleans the floor with a handheld cleaning device. The user starts the handheld cleaning device, and the power source device 700 starts to generate negative pressure. The dirt such as sewage is sucked into the sewage tank 14 with the airflow through the floor brush assembly 12. The sewage and airflow are separated in the sewage tank 14, and the sewage collects in the sewage tank 14. The air flows out of the sewage tank 14 through the air outlet holes of the sewage tank 14 and enters the power source device 700.

At this time, the airflow enters the air inlet holes of the air inlet path 7211 and enters the air inlet path 7211 inside the motor 721. Then, the airflow enters the air path between the motor and the muffler cover through the air inlet path 7211, to extend the flow path of the airflow. At the same time, the guiding holes 722a evenly provided on the muffler cover 722 are configured to adjust the airflow, to force the airflow to bypass the muffler cover 722, pass through the top of the muffler cover 722, and enter the air outlet path through the air guiding holes, so that the flow path of the air inlet path 7211 may be extended. Due to the extension of the flow path of the air inlet path 7211 and the air outlet path 712, and the airflow is adjusted through the guiding holes 722a on the muffler cover 722, high-frequency wind noise can be effectively reduced and the noise of cleaning device can be reduced.

Application Scenario 2

On the basis of application scenario 1, the flow path of the air inlet path 7211 and the air outlet path 712 is extended, and the airflow through the air guiding hole 722a on the muffler cover 722 is adjusted, the high-frequency wind noise is effectively reduced, and the noise of the cleaning device is reduced, the vibration isolation and sealing between the motor 721 and the lower cover of shell 71b are implemented by using the inlet sealing sleeve 724, and the vibration isolation and sealing between the motor 721 and the muffler cover 722 are implemented by using the inlet sealing sleeve 724 and the shock-absorbing pad 723. The vibration isolation and sealing between the motor assembly 72 and the upper cover of shell 71a are implemented by using the shock-absorbing pad 723, so that the noise caused by vibration may be reduced and the noise of the cleaning device is reduced.

In addition to noise reduction, current cleaning device further has a problem in cooling the battery. Cleaning device, such as surface wet cleaners, vacuum cleaners, are increasingly interested by users for their size, weight, safety, charging time, and other characteristics. Battery cooling is inextricably related to size, space, and arrangement, and cannot be achieved simultaneously. Therefore, it is necessary to make full use of the assembly of components and the arrangement of cells in a limited space to solve the problem of battery pack. The following will focus on improving the power source device of cleaning device from the perspectives of battery cooling, overall size optimization, and ease of operation.

The battery pack assembly 73 is disposed above the motor 721, as shown in FIG. 52a and FIG. 52b. Furthermore, the battery pack assembly 73 may include multiple cells, e.g., 5, 7, 8, 9, or more cells. There is no specific limitation on the numbers in the present embodiment. FIG. 53 shows an embodiment in which the battery pack assembly 73 includes 7 cells.

The cell 731 can be a soft-pack battery. A single cell 731 is rectangular, as shown in FIG. 53. With research and development verification, in order to fit the cell 731 into the power source shell 71 without affecting the heat dissipation of the cell, the cell 731 is arranged vertically and evenly inside the battery pack housing 732. As shown in FIG. 53, the arrangement direction of the cell 731 is parallel to the direction b of the connection line between the two gripping parts 75. The battery surface of the single cell 731 is perpendicular to the connection line bb between the two grip parts 75. In the direction of the connection line between the two gripping parts 75, there is a gap between adjacent cells. This allows cooling air to enter the gap to dissipate heat from the cells.

In an implementation, two adjacent cells 731 are separated at the end by foam, which may provide space for expansion due to heating of the soft-pack battery, and facilitate the passing of cooling airflow. As shown in FIG. 53, a cooling fan 76 is located on the side of the cell 731. Preferably, the cooling fan 76 is located on the side of the cell 731 facing an electrical connection 77, and the airflow blown by the cooling fan 76 flows through a gap between two adjacent cells. The arrangement of cells and the location of the cooling fan are all designed for the smaller diameter of the power source shell 71, which is a preferred arrangement. Otherwise, it would be difficult to fit the battery pack assembly into the power source shell 71. At the same time, this arrangement of cells and cooling fans can further ensure good heat dissipation and prevent excessive rising of temperature of the cells during charging, which may result in long waiting time for charging. The power source shell 71 with smaller diameter is described in detail below.

Furthermore, each cell is provided in parallel, and the end faces can be misaligned. This arrangement occupies less space and distributes heat evenly among the cells.

It should be noted here that the above-mentioned electrical connection part 77 refers to the part of the power source device 700 configured to be connected with the main body 10. The electrical connection part 77 can be a protrusion on the power source device, which can be set only in the middle region of the axial length of the power source device. In some embodiments, the electrical connection part 77 can extend along the axial direction of the power source device to the assembling end face of the power source device 700 and the main body 10. A recess matched with the protrusion can be provided at corresponding position on the main body for guiding of assembling. Alternatively, the cleaning device further includes a second body. For example, a product includes a main body and a second body. The main body can be a surface wet cleaner body, and the second body can be a vacuum cleaner module body. Connection structure matched with the electrical connection part 77, such as a recess groove may be provided at corresponding positions on the main body and the second body for guiding of assembling.

The above-mentioned grip part 75 is a part of the power source shell 71 that is convenient for holding the power source assembly with one hand. The grip part 75 can be a recessed structure formed on the power source shell 71. Specifically, the grip part can include two recessed portions on opposite sides of the power source shell 71. The surfaces of the recessed portions are lower than the outer contour surface of the power source shell 71 (the contour surface of the power source shell 71 excluding the recessed portion). When the user holds the power source device, a thumb of one hand holds one of the recessed portions, and the other four fingers of the same hand can hold the other recessed portion. In this way, the user can hold the power source device with one hand for assembling or disassembling.

The bracket of the battery pack assembly 73 is on an assembling side of the cooling fan 76, and other parts except the assembling part for the cooling fan 76 remain closed. In order to prevent airflow from flowing out from this side, as shown in FIG. 54, the other sides can be provided with cooling through-holes, which can be long through-holes in the figure or small round holes. The width of the long through-holes and the diameter of the round holes should not exceed 2 mm, because the soft-pack battery is relatively fragile, in order to prevent small screwdrivers or nails from scratching the soft-pack battery.

In another embodiment, as shown in FIG. 54, the cooling fan 76 can be located above the battery pack assembly 73, as long as the direction of the airflow blown by the cooling fan 76 is parallel to the gap between adjacent cells 731.

The positions for providing the cooling fan are exemplarily listed above in FIG. 53 and FIG. 54, in addition to the providing shown in the two figures, the cooling fan can be set in other positions, and the cooling fan may be provided in any area around, as long as the airflow of the cooling fan is parallel to the cells. Airflow parallel to the direction of cell arrangement can maximize the efficiency of dissipating heat from the cells to the motor heat exchange area and the external air heat exchange area for cooling.

Furthermore, the diameter of the power source shell 71 of the power source device can be 84-100 mm, specifically, the diameter of the power source shell 71 can be 92 mm, which is convenient for one-handed operation. That is, it is unnecessary to design a special holding structure to facilitate the assembling, disassembling, and transfer of the power source device by hand. At the same time, the diameter of the power source shell is limited to 84-100 mm, such as 92 mm, which ensures good heat dissipation while maintaining a small size.

Furthermore, the power source shell can be made of a material with a thermal conductivity greater than 0.7 W/m·k, which helps accelerate heat exchange. In one embodiment, the battery pack assembly 73 located above the motor 721 uses the fan 7 and the power source shell to dissipate heat. The airflow blown by the fan 7 flows through the gaps between adjacent cells and then comes into contact with the power source shell. Since the thermal conductivity of the power source shell is greater than 0.7 W/m·k, heat exchange and heat transfer are very rapid, and the heat can be quickly transferred to outside, and thus the heat from the battery pack assembly 73 may be dissipated.

On the other hand, as shown in FIG. 52a, the battery pack assembly 73 and the motor 721 are provided close to each other to use the motor 721 to discharge air. A cooling fan 76 is mounted on the battery pack assembly 73 and is mainly used to evenly dissipate the heat of the battery pack, blow the heat of the battery pack to the power source shell 71 and the heat exchange surface of the motor 721 for cooling the battery pack. The battery pack chamber area is extended to the motor area or the motor area is extended to the battery pack chamber to increase heat exchange area to accelerate the cooling.

With reference to the embodiment shown in FIG. 52a, one side of the battery pack assembly, as indicated by A in the figure, is closed. The surrounding and end surfaces exchange heat between the cold air sucked in by the motor 721 and the battery pack chamber area. Because one side of the battery pack assembly is closed, the air flows to the left as shown in FIG. 52a.

In another embodiment shown in FIG. 52b, the cold air sucked by the motor 721 enters the battery pack chamber area for heat exchange, and then enters the motor area to be discharged from the air outlet holes 7121 of the air outlet path 712 out of the power source device 700 as hot air.

The present disclosure further provides an embodiment in which a semiconductor cooling chip 725 is provided above the muffler cover 722 of the motor 721 (as shown in FIG. 55). The characteristic of the semiconductor cooling chip 725 is that the heating surface must have heat dissipation, otherwise the cooling surface cannot work and loses its effect. In this embodiment, the semiconductor cooling chip 725 includes a heating surface 7251 and a cooling surface 7252. The heating surface 7251 faces the motor 721, and the cooling surface 7252 faces the battery pack assembly 73. The cooling fan 76 is disposed between the battery pack assembly 73 and the semiconductor cooling chip 725. The motor 721 discharge air to dissipate heat from the heating surface 7251 to ensure that the cooling surface 7252 can be effectively used. When the semiconductor cooling chip is working, a cooling area 7253 is formed. Without the cooling fan 76, the heat exchange between the cold and hot air is slow. Therefore, a cooling fan 76 is added to the cooling area 7253 to exchange the cold air formed by the semiconductor cooling chip with the heat generated by the battery cells, so as to actively cool the battery pack components, even a ring temperature of 25° C.-60° C. can be obtained and the whole power of the device may have a full power range of 80 W-400 W, the batter may be charged at any time when using during the entire discharge cycle without any false charging of the battery pack.

Please refer to FIG. 56 to FIG. 64. The present disclosure provides a cleaning device, which can be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld surface wet cleaner, etc., which are well known to those skilled in the art. It can also be a self-moving cleaning device such as a sweeping robot, a scrubber robot, a sweeping and scrubber robot, etc., which is configured to clean the working surfaces such as the ground, sofa, carpet, etc. In the embodiment of the present disclosure where the cleaning device is a handheld surface wet cleaner, when the user uses the surface wet cleaner for cleaning work, he can push the surface wet cleaner to move on the ground and use the floor brush assembly of the surface wet cleaner to clean the working surface.

The cleaning device of the present disclosure may include a floor brush assembly and a sewage tank. The floor brush assembly includes a floor brush shell, a roller brush, and a roller brush cover. The floor brush shell is provided with a suction port, and the roller brush is configured to be rotationally connected to the floor brush shell. During the cleaning of the cleaning device, the roller brush comes into contact with the work surface to clean it, and the suction port can suck the sewage into the sewage tank.

The sewage tank includes a tank body, an end cap bracket, and a water overflow detecting component. The tank body is provided with a sewage inlet path to facilitate the entry of sewage on the working surface into the inner chamber through the sewage inlet path. A water blocking shell with a water blocking cavity is provided on the end cap bracket, and the sewage outlet of the sewage inlet path is configured to extend into the water blocking cavity of the water blocking shell. A water blocking assembly located on a side of the water blocking cavity is provided on the end cap bracket, and the water overflow detecting component is disposed outside the water blocking assembly. The water blocking assembly includes a first water blocking part and a second water blocking part. The first water blocking part is configured to separate the sewage flowing down from the bottom of the water blocking cavity from the water overflow detecting component. There is a gap between the second water blocking part and the side of the water blocking cavity, and the second water blocking part is configured to separate the water overflow detecting component from the gap.

It is understood that the first water blocking part can separate the sewage flowing down from the bottom of the water blocking cavity from the water overflow detecting component, so as to avoid the sewage flowing down from the bottom of the water blocking cavity from falling onto the water overflow detecting component. There is a gap between the second water blocking part and the side of the water blocking cavity, and the second water blocking part can isolate the water overflow detecting component from the gap. Therefore, when the sewage in the water blocking cavity flows down from the gap, the second water blocking part can separate the sewage flowing down from the gap from the water overflow detecting component, so as to avoid the sewage flowing down from the gap from falling onto the water overflow detecting component. The water blocking component of the present disclosure can prevent the water overflow detecting component from misreporting due to the sewage flowing down from the water blocking cavity, ensure the normal operation of the cleaning device, and effectively improve the user experience.

For better understanding, the specific structure and working principle of the cleaning device of the present disclosure are described in detail with reference to FIGS. 56 to 64 in conjunction with one embodiment.

The present disclosure provides a cleaning device for cleaning work surfaces such as floors and carpets. The cleaning device at least includes a sewage tank for storing sewage sucked from the working surface.

It is understood that the cleaning device may further include a body, a floor brush assembly, and a fan assembly. The body serves as a bearing part for mounting various functional components required for the cleaning device. The floor brush assembly is disposed at the bottom end of the body and is used for cleaning the work surface. The floor brush assembly includes a floor brush shell, a roller brush, and a roller brush cover. The floor brush shell is provided with a suction port, and the roller brush is configured to be rotatably connected to the floor brush shell. During the cleaning of the cleaning device, the roller brush comes into contact with the work surface for cleaning of the work surface.

The fan assembly is configured to create negative pressure inside the sewage tank, so that the sewage on the working surface may be sucked into the interior of the sewage tank through the suction port on the floor brush shell under the action of negative pressure. The sewage can include only dirty water, or a mixture of dirty water and solid waste.

As shown in FIG. 56 to FIG. 58, the sewage tank includes a tank body 81, an end cap bracket 82, and a water overflow detecting component 83. The tank body 81 is provided with a sewage inlet path 812 that communicates with an inner cavity 811, to allow sewage on the working surface to enter the inner cavity 811 through the sewage inlet path 812.

A water blocking shell 821 with a water blocking cavity 822 is provided on the end cap bracket 82, and the sewage outlet 8121 of the sewage inlet path 812 is configured to extend into the water blocking cavity 822 of the water blocking shell 821. As shown in FIG. 57, in one embodiment of the present disclosure, the end cap bracket 82 is also provided with an air outlet hole 823, and the water blocking shell 821 is configured to isolate the water blocking cavity 822 from the air outlet hole 823, so that when the sewage in the sewage inlet path 812 flows out from the sewage outlet hole 8121, it may be blocked in the water blocking cavity 822, and may not be directly sucked into the air outlet hole 823 by the fan assembly. In this way, sewage may be prevented from being sucked into the fan assembly through the air outlet hole 823, and the fan assembly may be prevented from being unable to work normally due to water ingress.

The structure of the water blocking shell 821 can have various forms. Specifically, as shown in FIG. 59 and FIG. 60, in one embodiment of the present disclosure, the water blocking shell 821 includes a connecting wall 8212 and enclosing side walls 8211 located on opposite sides of the connecting wall 8212, and a water blocking cavity 822 with an open end may be formed by the enclosing of the connecting wall 8212 and enclosing side walls 8211. Further, as shown in FIG. 59 and FIG. 60, the water blocking cavity 822 is provided with an open end opposite to the connecting wall 8212, i.e., the open end is located on the side of the water blocking shell 821 opposite to the connecting wall 8212, which can also be understood as a C-shaped or U-shaped structure with an open end enclosed by the connecting wall 8212 and enclosing side walls 8211. After the end cap bracket 82 is mounted in the tank body 81, the open end of the water blocking shell 821 faces the inner wall of the tank body 81, and the inner wall of the tank body 81 can cover the open end, so as to allow the tank body 81 and the water blocking shell 821 to jointly enclose a square water blocking cavity 822; the tank body 81 can be at a certain distance away from the open end, and enclose with the water blocking shell 821 to form a square water blocking cavity 822 with openings formed on the sides thereof.

In other embodiments of the present disclosure, a sealing wall may be further provided on the other side of the opposing connecting wall 8212, so that the enclosing of the connecting wall 8212, the enclosing side wall 8211, and the sealing wall may form a water blocking cavity 822. There is no limitation in the present embodiment. The water overflow detecting component 83 is configured to be triggered when the sewage tank is in a full state, so as to timely control the floor brush assembly and fan component to stop in time, to avoid overflowing of sewage in the sewage tank, and notify the user to promptly empty the dirty water in the sewage tank.

As shown in FIG. 58 and FIG. 60, the end cap bracket 82 is provided with a water blocking assembly 824 located on the side of the water blocking cavity 822, and the water overflow detecting component 83 is disposed outside the water blocking assembly 824. The water blocking assembly 824 includes a first water blocking part 8241 and a second water blocking part 8242. The first water blocking part 8241 is configured to separate the sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83. There is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 is configured to separate the water overflow detecting component 83 from the gap 8245.

It is understood that the first water blocking part 8241 can separate the sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the bottom of the water blocking cavity 822 from falling onto the water overflow detecting component 83. There is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 can separate the water overflow detecting component 83 from the gap 8245. Therefore, when the sewage in the water blocking cavity 822 flows down from the gap 8245, the second water blocking part 8242 can separate the sewage flowing down from the gap 8245 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the gap 8245 from falling onto the water overflow detecting component 83. The water blocking assembly 824 of the present disclosure can prevent the water overflow detecting component 83 from making false alarms due to the large amount of sewage flowing out of the water blocking cavity 822, and ensure the normal operation of the cleaning device and effectively improve the user's experience.

In one example, the first water blocking part 8241, the second water blocking part 8242, and the partition part 8243 are integrated on the water blocking assembly 824. The first water blocking part 8241 is formed by downward extension of the enclosing side wall 8211, and the second water blocking part 8242 and the partition part 8243 are formed on the side of the water blocking assembly 824. Of course, in other examples, the first water blocking part 8241, the second water blocking part 8242, and the partition part 8243 can be independent of the water blocking assembly 824.

As shown in FIG. 57, in one embodiment of the present disclosure, the water overflow detecting component 83 and the air outlet hole 823 are located on respective sides of the connecting wall 8212 in the thickness direction of the sewage tank. In this way, after the sewage flows out of the water blocking cavity 822, it may be deflected toward the side where the air outlet holes 823 are located under the action of airflow and fall into the sewage tank, so as to make the trajectory of the sewage away from the water overflow detecting component 83, so that the sewage may be further prevented from contaminating the water overflow detecting component 83.

As shown in FIG. 58, in one embodiment of the present disclosure, the water blocking assembly further includes a fixed part 8213 located at the top of the water blocking assembly 824, and the water overflow detecting component 83 is configured to extend downward from the fixed part 8213. There is a gap between the water overflow detecting component 83 below the fixed part 8213 with the water blocking assembly 824.

With the fixed part 8213, it is convenient for the water overflow detection component 83 to extend down to the target position. Due to the gap between the water overflow detection component 83 and the water blocking part 824, even if some sewage is attached to the water blocking part 824, it is difficult for the sewage to contaminate the water overflow detection component 83, so as to further prevent the water overflow detection component 83 from making false alarms.

Furthermore, as shown in FIG. 58, in one embodiment of the present disclosure, the fixed part 8213 is configured to extend downward to a position not exceeding half the height of the connecting wall 8212. In this way, the water overflow detecting component 83 may be ensured to be exposed from the fixed part 8213 for a longer length, so that the top of the water overflow detecting component 83 can maintain being at a certain distance from the bottom edge of the connecting wall 8212, to avoid the sewage from attaching to the water overflow detecting component 83 after flowing down from the connecting walls 8212, due to the short exposure of the water overflow detecting component 83 from the fixed part 8213.

The water overflow detecting component 83 can be various types of remote water overflow detecting components such as optical detection components and resistance detection components. When the water overflow detecting component 83 is a resistance detection component, in one embodiment of the present disclosure, as shown in FIG. 58, the water overflow detecting component 83 includes a first probe 831 and a second probe 832 disposed on respective sides of the water blocking shell 821. During the operation of the water overflow detecting component 83, when the resistance between the measuring point 833 of the first probe 831 and the measuring point 833 of the second probe 832 is less than a preset value, the two probes can be conducted, so that an overflow signal is issued to the cleaning device.

Specifically, as shown in FIG. 58, in one embodiment of the present disclosure, the first probe 831 and the second probe 832 can include a connecting section 834 and a measuring point 833. The first probe 831 and the second probe 832 are entirely composed of conductive plastic, and the measuring point 833 is formed by adding a metal layer on the conductive plastic. The connecting section 834 is coated with an insulating layer composed of hydrophobic material, which can reduce the adhesion of sewage.

It is understood that during the normal operation of the cleaning assembly, the sewage on the working surface will be continuously sucked into the inner cavity 811 of the sewage tank. When the sewage tank is in the full state, the measuring point 833 of the first probe 831 and the measuring point 833 of the second probe 832 will both be soaked in sewage. Since the resistance of sewage is much lower than that of air, the first probe 831 and the second probe 832 can be conducted, and the water overflow detection component 83 sends a signal of fullness in the sewage tank to the cleaning device to remind the user to empty the sewage in the sewage tank.

During the operation of the cleaning assembly, when a large amount of sewage falls from the water blocking cavity 822 at the same time, such sewage may contact the measuring points 833 of the first probe 831 and the second probe 832 simultaneously, to make the first probe 831 and the second probe 832 conduct in advance, resulting in a false alarm from the water overflow detection component 83. At this time, the sewage tank has not been in the full state, and only less sewage user can pour from the sewage tank.

When the sewage tank is still and not full, but the end cap bracket 82 is attached with some sewage, and this part of sewage can make the first probe 831 and the second probe 832 conduct, the water overflow detection component 83 may send a full signal to the cleaning device, which may cause false alarms. And only after the user empty this part of sewage, the water overflow detection component 83 can work normally, which not only increases the user's workload, but also affects the user's experience. Therefore, as shown in FIG. 59 and FIG. 61, in one embodiment of the present disclosure, the water blocking assembly 824 is configured to extend downward beyond the bottom edge of the connecting wall 8212; the measuring points 833 of the first probe 831 and the second probe 832 are lower than the bottom edge of the connecting wall 8212, and higher than the bottom edge of the water blocking assembly 824.

It is understood that when the water overflow detecting component 83 includes the first probe 831 and the second probe 832 provided on respective sides of the water blocking shell 821, two corresponding water blocking assemblies 824 are provided on respective sides of the water blocking cavity 822, and the first probe 831 and the second probe 832 are provided outside the corresponding water blocking assembly 824, so as to prevent the sewage falling from the water blocking cavity 822 from landing on the first probe 831 and the second probe 832, and prevent the water overflow detecting component 83 from misreporting due to the large amount of sewage scattered below the water blocking cavity 822.

Furthermore, the measuring points 833 of the first probe 831 and the second probe 832 are located below the bottom edge of the water blocking shell 821 and above the bottom edge of the water stopper 824, therefore when the sewage tank is still and not full, the sewage attached to the end cap bracket 82 needs to bypass the water blocking shell 821 and pass through the measuring points 833 extending downward from the water blocking shell 821 to the first probe 831 and the second probe 832 to conduct the first probe 831 and the second probe 832, which greatly extends the distance required for the sewage to climb the walls, increases the difficulty of conducting the first probe 831 and the second probe 832, and reduces the possibility of conducting the first probe 831 and the second probe 832, so that false alarms from the water overflow detection component 83 may be avoided, and the normal operation of the cleaning device may be ensured, the user's workload may be reduced, and the user's experience may be improved.

In order to further increase the distance required for the dirt attached to the end cap bracket 82 to climb walls, as shown in FIG. 62, in one embodiment of the present disclosure, the connecting wall 8212 is configured to protrude from an edge of the first water blocking part 8241 in the horizontal direction. FIG. 60 is a sectional view of the sewage tank of the present disclosure on a horizontal plane. With reference to the viewing direction of FIG. 60, the water blocking assembly 824 is positioned substantially vertically within the tank body 81 when the end cap bracket 82 is mounted inside the tank body 81, and the connecting wall 8212 protrudes backward from the edge of the first water blocking part 8241 in the horizontal direction.

In this way, when the sewage tank is standing still and not full, if the sewage attached to the end cap bracket 82 wants to conduct the first probe 831 and the second probe 832, it not only needs to pass through the measuring point 833 extending downward from the water blocking shell 821 to the first probe 831 and the second probe 832, but also needs to bypass the connecting wall 8212 protruding from the edges of the two first water blocking parts 8241 on the water blocking shell 821. It can be seen that with the connecting wall 8212 protruded from the edge of the first water blocking part 8241, the distance required for the sewage to climb walls is further extended, which further increases the difficulty of the sewage to conduct the first probe 831 and the second probe 832, and further reduces the possibility of the sewage to conduct the first probe 831 and the second probe 832, and reduces the possibility of false alarm of the water overflow detection component 83.

In order to further avoid the false alarm of the water overflow detecting component 83 caused by the scattering of a large amount of sewage under the water blocking cavity 822, as shown in FIG. 63 and FIG. 64, in one embodiment of the present disclosure, the part of the water blocking assembly 824 below the bottom edge of the connecting wall 8212 is configured to extend inwardly and obliquely. In this way, the water blocking assembly 824 can guide the sewage falling from the lower part of the water blocking cavity 822 to fall from the center position of the water blocking shell 821, so as to further avoid the false alarm of the water overflow detecting component 83 caused by the scattering of a large amount of dirt under the water blocking cavity 822. In order to prevent large solid wastes in the sewage from entering the inner cavity 811 and being attached to the outer wall of the water blocking shell 821, causing false alarm of the water overflow detecting component 83, and also to facilitate the cleaning of solid wastes, as shown in FIG. 59, in one embodiment of the present disclosure, the water blocking shell 821 includes a solid-liquid separation frame 825, and part of the side wall of the solid-liquid separation frame 825 is configured to cooperate with the first water blocking part 8241; the second water blocking part 8242 is configured to extend from the first water blocking part 8241 so that there is a gap 8245 between the second water blocking part 8242 and the side wall of the solid-liquid separation frame 825; the sewage flowing out of the side wall of the solid-liquid separation frame 825 is configured to flow downward through the gap 8245.

It can be seen that the solid-liquid separation frame 825 can be mounted on the enclosing side wall 8211 or connecting wall 8212 through the open end, and the space enclosed by the solid-liquid separation frame 825 is the aforementioned water blocking cavity 822. The sewage flowing out of the sewage inlet path 812 is configured to flow through the solid-liquid separation frame 825 into the tank body 81.

With a solid-liquid separation frame 825 in the water blocking cavity 822, after the sewage mixed with solid waste flows from the sewage outlet hole 8121 of the sewage inlet path 812 into the water blocking cavity 822, the larger solid waste particles may be blocked by the solid-liquid separation frame 825 and remain in the solid-liquid separation frame 825, while the remaining sewage may flow through the solid-liquid separation frame 825 into the tank body 81. In this way, large pieces of solid waste in the sewage may be prevented from entering the inner cavity 811, so as to prevent large pieces of solid waste from being attached to the outer wall of the water blocking shell 821, which may make sewage flow into the first probe 831 and the second probe 832. Moreover, when users clean the garbage in the sewage tank, it is also convenient for users to separately handle the larger solid waste particles and the remaining sewage, and thus the user's workload may be reduced.

Specifically, as shown in FIG. 59, in one embodiment of the present disclosure, the solid-liquid separation frame 825 includes a peripheral wall and a bottom wall that are shaped to fit the shape of the water blocking cavity 822. The peripheral wall is shaped to fit the shape of the water blocking cavity 822, and is in a C or U shape. In this way, the solid-liquid separation frame 825 further has an opening on the side of opening end of the water blocking cavity 822, so that solid waste can be removed from the opening. Moreover, in one embodiment of the present disclosure, the solid-liquid separation frame 825 can be detachably disposed in the water blocking cavity 822. Specifically, the solid-liquid separation frame 825 can have a deformation ability, and the solid-liquid separation frame 825 is mounted on the inner wall of the water blocking cavity 822 by the deformation of its peripheral wall. After the solid-liquid separation frame 825 is mounted in the water blocking cavity 822, the parts of the peripheral wall of the solid-liquid separation frame 825 on the opposite sides are exposed outside the enclosing side wall 8211. In this way, when the user needs to empty solid dirt or clean the solid-liquid separation frame 825, the user can first remove the end cap bracket 82 from the tank body 81, and then hold the solid-liquid separation frame 825 by the exposed part of the enclosing side wall 8211, so that the solid-liquid separation frame 825 can be removed from the water blocking cavity 822 as a whole.

As shown in FIG. 59, in one embodiment of the present disclosure, the bottom wall of the solid-liquid separation frame 825 is provided with a leakage hole 8252, and some of the sewage flowing out of the sewage inlet path 812 is configured to flow down into the tank body 81 through the leakage hole 8252. Similarly, as shown in FIG. 59, in one embodiment of the present disclosure, the two side walls of the circumferential wall of the solid-liquid separation frame 825 are provided with liquid outlet holes 8251, and there is a gap 8245 between the second water blocking part 8242 and the liquid outlet holes 8251 on the side wall of the solid-liquid separation frame 825; the sewage flowing out of the liquid outlet holes 8251 is configured to flow down through the gap 8245. In this way, after the sewage flows from the sewage outlet hole 8121 of the sewage inlet path 812 into the water blocking cavity 822, some of the sewage can flow out through the liquid outlet holes 8251 on the side wall of the solid-liquid separation frame 825 and then flow into the lower inner cavity 811.

The particle size of the solid waste trapped in the solid-liquid separation frame 825 can be adjusted by adjusting the size of the aperture of the liquid outlet hole 8251 and the liquid leakage hole 8252. The sewage can flow smoothly out of the solid-liquid separation frame 825, while the solid waste in the sewage may be trapped in the solid-liquid separation frame 825 as much as possible, by setting the aperture of the liquid outlet hole 8251 and the liquid leakage hole 8252 to an appropriate size.

As shown in FIG. 59, in another embodiment of the present disclosure, the second water blocking part 8242 is configured to extend from the first water blocking part 8241 towards the opening direction of the water blocking cavity 822, and the distance between the two second water blocking parts 8242 is greater than the distance between the two first water blocking parts 8241. In this way, it is convenient to form a gap 8245 between the second water blocking part 8242 and the side wall of the solid-liquid separation frame 825.

Furthermore, as shown in FIG. 60, the second water blocking part 8242 is configured to extend towards the side wall of the tank body 81 to form a gap with the side wall of the tank body 81 or contact with the side wall of the tank body 81. In this way, during the operation of the cleaning device of the present disclosure, air is basically unable to flow from the side of the second water blocking part 8242 to the air outlet holes 823, and can only flow around from the bottom of the water blocking shell 821 to the air outlet holes 823, which will not bring sewage to bypass the water blocking assembly 824 and reach the vicinity of the water overflow detecting component 83, thus avoiding sewage from being attached to the water overflow detecting component 83.

Furthermore, as shown in FIG. 58 and FIG. 60, in one embodiment of the present disclosure, a partition part 8243 extending towards the side wall of the tank body 81 is provided on the water blocking assembly 824. The partition part 8243 is configured to form an angle with the first water blocking part 8241 and the second water blocking part 8242, and is configured to extend to form a gap with the side wall of the tank body 81 or contact with the side wall of the tank body 81. There is open space between the partition part 8243 and the first water blocking part 8241.

With the partition part 8243, sewage may be further prevented from direct flowing from the side of the water blocking shell 821 to the air outlet 823, so as to further avoiding the sewage from being brought by air to bypass the water blocking assembly 824 and reach the vicinity of the water overflow detecting component 83, to prevent the water overflow detecting component 83 from issuing false alarms. Moreover, there is open space between the partition part 8243 and the first water blocking part 8241, so that the air near the water overflow detecting component 83 can flow normally, and the situation may not happen that the water overflow detecting component 83 does not report or reports late after the sewage tank becomes full due to the failure of air to flow normally.

As shown in FIG. 58 and FIG. 60, in one embodiment of the present disclosure, the partition part 8243 is configured to extend outward from the position where the first water blocking part 8241 and the second water blocking part 8242 are connected, and the first probe 831 and the second probe 832 are configured to be located in the partition groove 8244 formed by the first water blocking part 8241 and the partition part 8243. The first probe 831 and the second probe 832 are located in the partition groove 8244 formed by the first water blocking part 8241 and the partition part 8243, therefore the partition groove 8244 can protect the first probe 831 and the second probe 832, so as to prevent sewage from flowing near the first probe 831 and the second probe 832 as much as possible after flowing out of the water blocking cavity 822.

As shown in FIG. 60, in one embodiment of the present disclosure, the partition part 8243 is configured to be approximately perpendicular to the first water blocking part 8241 and the second water blocking part 8242, and the partition part 8243, the first water blocking part 8241, and the second water blocking part 8242 are configured to be integrally formed with the water blocking shell 821. The partition part 8243 is configured to be approximately perpendicular to the first water blocking part 8241 and the second water blocking part 8242, therefore the space inside the partition groove 8244 can be sufficiently large, so as to reduce the probability that sewage accumulate in the partition groove 8244. Even if sewage accumulates, users can easily clean the partition groove 8244 to further ensure that the entire partition groove 8244 is in an open state, so as to ensure that the air near the first probe 831 and the second probe 832 can flow normally.

Moreover, the partition part 8243, the first water blocking part 8241, the second water blocking part 8242, and the water blocking shell 821 are integrally formed, therefore it is possible to save the connection structure among the partition part 8243, the first water blocking part 8241, the second water blocking part 8242, and the water blocking shell 821, and to enhance the connection strength among the partition part 8243, the first water blocking part 8241, the second water blocking part 8242, and the water blocking shell 821, and to reduce the required processing steps of the end cap bracket 82.

Furthermore, as shown in FIG. 58 and FIG. 60, in one embodiment of the present disclosure, the gap 8245 between the first probe 831, the second probe 832, and the corresponding partition groove 8244 is no less than 2 mm. In this way, even if some sewage is attached to the partition groove 8244, the sewage droplets cannot directly be communicated with the measuring points 833 of the first probe 831 and the second probe 832, so as to further prevent the first probe 831 and the second probe 832 from being conduct by false.

It is understood that in one embodiment of the present disclosure, the cleaning device is configured to be inclined relative to the working surface during operation; the first probe 831 and the second probe 832 are configured to be located above the partition groove 8244 when the cleaning device is in the working state. That is, taking the direction in FIG. 57 as an example, when the cleaning device is working, the first probe 831 and the second probe 832 are located above the partition groove 8244, and thus some sewage can flow from the side below the first probe 831 and the second probe 832 along the inclined tank body 81 to the inner cavity 811, so as to avoid the impact of sewage on the tank body 81, and avoid the large amount of dirt from being dispersed below the water blocking cavity 822, which may cause the water overflow detecting component 83 to make false alarms. Moreover, it is also possible to locate the air outlet holes above the water blocking cavity 822, so as to avoid the sewage form being sucked into the air outlet holes 823 by the fan assembly, and thus avoid water from entering the fan assembly.

The present disclosure further provides a solution tank, which includes:

    • a tank body 81 provided with a liquid inlet path inside;
    • an end cap bracket 82 provided with a water blocking shell 821 having a water blocking cavity 822, the sewage outlet hole 8121 of the liquid inlet path is configured to extend into the water blocking cavity 822 of the water blocking shell 821;
    • a water overflow detecting component 83;
    • wherein the end cap bracket 82 is provided with a water blocking assembly 824 located on a side of the water blocking cavity 822, and the water overflow detecting component 83 is disposed outside the water blocking assembly 824, the water blocking assembly 824 includes a first water blocking part 8241 and a second water blocking part 8242, and the first water blocking part 8241 is configured to separate the sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83, and there is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 is configured to separate the water overflow detecting component 83 from the gap 8245.

The solution tank can effectively avoid false alarms from the water-level detection component 83. The solution tank can be the sewage tank mentioned above, or it can be configured to store other liquids. For specific structure and principle, please refer to the previous description, which is not repeated here.

In one embodiment of the present disclosure, a control method for a cleaning device is further provided, which is implemented by the above-mentioned cleaning device and includes the following steps: when the equivalent resistance of the water overflow detecting component is less than a first threshold value and keeps conductive for a first predetermined time, issuing an overflow signal.

In one embodiment of the present disclosure, when the equivalent resistance of the water overflow detecting component being conducted is greater than the first threshold and less than the second threshold value and keeps conductive for a second predetermined time, issuing an overflow signal.

In the embodiment of the water overflow detecting component 83 of the present disclosure, which includes a first probe 831 and a second probe 832, it is determined whether the current sewage tank is full based on whether the equivalent resistance between the two probes reaches a threshold value and the duration of conduction.

In one embodiment of the present disclosure, for example, when the sewage in the sewage tank reaches the measuring points of the two probes, the two probes are conducted, and it is determined in the detection loop that the equivalent resistance between the two probes is less than the first threshold value, and the two probes are kept being conductive for the first predetermined time, it is concluded that the current sewage tank is in a full state, and thus an overflow signal is emitted.

In one embodiment of the present disclosure, it is determined in the detection loop that the equivalent resistance between two probes is greater than the first threshold value and less than the second threshold value, and the two probes are kept being conductive for the second predetermined time, it is concluded that the current sewage tank is in a full state. This is because the environment in the sewage tank is complex, and foam may be generated on the surface of the sewage when the sewage falls from the water blocking cavity. In addition, when the user holds the cleaning device in the process of cleaning, the sewage may shake in the sewage tank and generate foam on the surface of the sewage. A large amount of foam generated in the waste water bucket may overflow from the waste water bucket. Therefore, when the two probes detect foam, it should also be concluded that the current sewage tank is full of water.

That is, in the present disclosure, two probes are used to detect whether the foam on the surface of the sewage reaches a predetermined height with the sewage. The foam is mixed with air and sewage, therefore when the foam reaches the measuring points of the two probes, the equivalent resistance of the two probes after being conducted is greater than the equivalent resistance of the two probes being conducted by sewage. Therefore, when the equivalent resistance between the two probes is determined to be greater than the first threshold and less than the second threshold in the detection loop, and the two probes are kept being conductive for the second predetermined time, it can be concluded that the current state is a state of being conducted by foam.

The first threshold value and the second threshold value in the present disclosure can be determined according to the specific situation of sewage and foam. In a specific embodiment of the present disclosure, the first threshold value can be 250 kΩ, and the second threshold value can be 350 kΩ, depending on the actual situation of the specific detection loop. In this embodiment, according to the characteristics of foam, the second threshold can be set to 1.1-1.5 times of the first threshold. In addition, the first threshold and the second threshold can also be numerical ranges, which will not be specifically explained here.

In addition, the second predetermined time in the present disclosure can be larger than the first predetermined time, because the situation of the two probes being conducted by foam is more complicated than that of the two probes being conducted by sewage, the second predetermined time used for determining the conductive state by foam is larger than the first predetermined time for determining the conductive state by sewage, so as to avoid the occurrence of accidental triggering. For example, in one embodiment of the present disclosure, the first predetermined time can be 1.5 s, and the second predetermined time can be 5 s, which can be selected according to actual needs. In this embodiment, according to the characteristics of foam, for better accuracy in determining, the second predetermined time is more than 3 times of the first predetermined time. In addition, the first predetermined time and the second predetermined time can also be numerical ranges, which will not be specifically described here.

In other embodiments, it is also possible to determine the overflow state in a variety of different scenarios based on the combination of the equivalent resistances between the two probes and durations. The above description only takes the foam scenario and the liquid scenario as an example.

Application Scenario

The present disclosure provides a cleaning device, which can be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld surface wet cleaner, etc., which are well known to those skilled in the art. It can also be a self-moving cleaning device such as a sweeping robot, a scrubber robot, or a robot that integrates functions of sweeping and scrubber for cleaning work surfaces such as floors, sofas, and carpets. In the embodiment of the present disclosure where the cleaning device is a handheld surface wet cleaner, when a user uses the surface wet cleaner for cleaning work, the user can push the surface wet cleaner to move on the floor and use the floor brush assembly of the surface wet cleaner to clean the work surface.

The cleaning device of the present disclosure may include a floor brush assembly and a sewage tank, and the floor brush assembly includes a floor brush shell, a roller brush, and a roller brush cover. The floor brush shell is provided with a suction port, and the roller brush is configured to be rotationally connected to the floor brush shell. During the cleaning of the cleaning device, the roller brush comes into contact with the working surface to clean it, and the suction port can suck the sewage into the sewage tank for disposal.

The sewage tank includes a tank body 81, an end cap bracket 82, and a water overflow detecting component 83. The tank body 81 is provided with a sewage inlet path 812, which facilitates the entry of sewage on the working surface into the inner cavity 811 through the sewage inlet path 812. The end cap bracket 82 is provided with a water blocking shell 821 having a water blocking cavity 822, and the sewage outlet hole 8121 of the sewage inlet path 812 is configured to extend into the water blocking cavity 822 of the water blocking shell 821. The end cap bracket 82 is provided with a water blocking assembly 824 located on a side of the water blocking cavity 822, and the water overflow detecting component 83 is disposed outside the water blocking assembly 824. The water blocking assembly 824 includes a first water blocking part 8241 and a second water blocking part 8242. The first water blocking part 8241 is configured to separate sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83. There is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 is configured to separate the water overflow detecting component 83 from the gap 8245.

It is understood that the first water blocking part 8241 can separate the sewage flowing down from the bottom of the water blocking cavity 822 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the bottom of the water blocking cavity 822 from falling onto the water overflow detecting component 83. There is a gap 8245 between the second water blocking part 8242 and the side of the water blocking cavity 822, and the second water blocking part 8242 can isolate the water overflow detecting component 83 from the gap 8245. Therefore, when the sewage in the water blocking cavity 822 flows down from the gap 8245, the second water blocking part 8242 can isolate the sewage flowing down from the gap 8245 from the water overflow detecting component 83, so as to prevent the sewage flowing down from the gap 8245 from falling onto the water overflow detecting component 83. The water blocking assembly 824 of the present disclosure can prevent the water overflow detecting component 83 from making false alarms due to the large amount of sewage flowing out of the water blocking cavity 822, and ensure the normal operation of the cleaning device and effectively improve the user's experience.

Please refer to FIG. 65 to FIG. 80. The present disclosure provides a cleaning device and a cleaning assembly, which are described in detail below. It should be noted that the order of description of the following embodiments does not limit the preferred order of the embodiments of the present disclosure. In the following embodiments, the descriptions of each embodiment have different points. For parts not described in details in one embodiment, please refer to the relevant descriptions of other embodiments.

The embodiments of the present disclosure provide a cleaning device, which can be a handheld vacuum cleaner, a surface wet cleaner, a carpet cleaning machine, a desktop cleaner, a surface cleaning machine, a cleaning robot, or other devices for cleaning. There is no limitation thereon in the present embodiment. Here, please refer to FIG. 65, the cleaning device includes a cleaning assembly 910. Please refer to FIG. 66 and FIG. 68, the cleaning device further includes a main body 920 and a roller brush component 930.

The main body 920 constitutes the main external profile of the cleaning device, and can be used as the structural foundation of the cleaning device for connecting and carrying the remaining components of the cleaning device.

The main body 920 may include a housing of the cleaning device, and the main body 920 may be further provided with a wheel body and other traveling components, a controller and other control components, a suction source, a steam generation component, etc. There is no limitation thereon in the present embodiment. Here, the controller can control the wheel body, the suction source, the steam generation component, and other components according to preset instructions or real-time instructions from the user. This is well known to those skilled in the art, and this embodiment will not repeat it.

In another example, the cleaning device is a surface wet cleaner, including a main frame and a main body 920. The main frame is rotationally connected to the main body 920. The main frame is provided with a handle, and the user can push and pull the cleaning device by the handle to complete the floor cleaning. The main frame is further provided with a clear water tank, a recycling tank, a suction source, and a battery, etc. The main body 920 serves as the floor brush of the cleaning device, and is provided with cleaning solution distribution components such as a water spray plate, cleaning parts such as a roller brush, a suction port, etc. The water in the clear water tank is sprayed by the cleaning solution distribution component to the cleaning components or the floor, and the cleaning components move (such as the rotation of the roller brush), the suction source works to generate suction force, and the dirt (sewage and solid waste) is sucked through the suction port to the recycling tank, so as to complete the floor cleaning.

The roller brush assembly 930 is disposed on the main body 920 for cleaning the to-be-cleaned surface. Here, the roller brush assembly 930 is disposed on the side of the main body 920 near the to-be-cleaned surface. Here, the roller brush assembly 930 generally has an axis and can rotate around its axis to achieve the cleaning function. Here, in order to facilitate the description of the positional relationship of various components, in the embodiment of the present disclosure, a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other are used, wherein the first direction X is the forward direction of the cleaning device when it is operating, the cleaning device has a first side and a second side that are opposite along the first direction X. Specifically, the second side is the front side and the first side is the rear side in the forward direction. The second direction Y is parallel to or coincides with the axis direction of the roller brush assembly 930. In view of the fact that the to-be-cleaned surface is usually the ground or a plane that is roughly parallel to the ground, the third direction Z can usually be set to be the vertical direction.

With reference to FIG. 66 and FIG. 68, the cleaning assembly 910 has an assembly part 91a and a cleaning part 91b. Here, the assembly part 91a and the cleaning part 91b are two components that are connected together after being clamped together. Of course, in other embodiments, the assembly part 91a and the cleaning part 91b can also be connected together in other ways, such as by bolting, welding, or integrating together. There is no limitation thereon in the present embodiment.

The assembly part 91a is configured to be assembled with the main body 920 to fix the relative positional relationship between the cleaning assembly 910 and the main body 920. After the assembly part 91a is connected with the main body 920, the cleaning part 91b is located on the side of the main body 920 close to the to-be-cleaned surface, so that the cleaning part 91b can clean the to-be-cleaned surface. The cleaning part 91b can be a scraper strip or the like, which is configured to scrape water stains on the ground to keep the ground clean. Of course, there is no limitation thereon in the present embodiment. Generally, along the first direction X, the cleaning assembly 910 is provided on the first side of the roller brush assembly 930, that is, the cleaning assembly 910 is located on the rear side of the roller brush assembly 930. Therefore, in using, the roller brush assembly 930 passes through the to-be-cleaned surface first, and then the cleaning part 91b passes through the to-be-cleaned surface.

Here, please refer to FIG. 66 and FIG. 69. Due to various factors such as processing errors and assembly errors, there may be an assembly gap between the main body 920 and the cleaning assembly 910. Residual water may leak through the assembly gap in the first direction X towards the rear side and accumulate at the rear side of the cleaning assembly 910.

Here, in some examples, when the cleaning device is working, the cleaning device sprays cleaning media such as cleaning solution onto the roller brush assembly 930, and the roller brush assembly 930 wipes the to-be-cleaned surface to make it clean. In addition, the cleaning device is further provided with a suction port, and under the action of the suction source, the sewage containing water is sucked to the sewage container of the cleaning device through the suction port. During the process of sucking the sewage, the sewage may contact the cleaning part 91b and leave a residue of water on the cleaning part 91b, which may leak backward along the assembly gap. Similarly, when the cleaning device is placed on the bearing part 940 for self-cleaning, during the sucking of cleaning media such as cleaning solution, the cleaning media may also contact the cleaning part 91b and leave a residue of water on the cleaning part 91b. Of course, the formation of residual liquid is not limited to the above example, and the residual liquid may further come from the to-be-cleaned surface or from the steam generating component of the cleaning device, etc. This embodiment does not constitute an undue limitation thereon. For example, the steam generated by the steam generating component is sprayed onto the roller brush assembly 930 or the to-be-cleaned surface to better clean the to-be-cleaned surface, and the residual liquid after cleaning will leak backward along the assembly gap. The steam generating component may include a heating body and a pipeline, etc. The pipeline is configured to supply liquid water to the heating body, and output the steam from the outlet of the heating body to the roller brush assembly 930 or the to-be-cleaned surface.

Here, please refer to FIG. 70, which shows the structure of a bearing part 940, which can be a tray or a base station, etc., and is provided with a receiving slot 941 for receiving the bottom structure of the cleaning device, so as to achieve the functions of carrying, cleaning and/or charging of the cleaning device.

When the cleaning device is carried on the bearing part 940, the accumulated liquid may generally accumulate in the area C shown in the figure, which may cause water accumulation in the central area of the bearing part 940.

Therefore, in the embodiment of the present disclosure, with reference to FIG. 71 and FIG. 72, two protrusions 9111 are provided on the assembly part 91a, and a first water passing hole 9112 is provided between the two protrusions 9111. The protrusions 9111 are provided on opposite sides of the first water passing hole 9112 along the second direction Y, i.e., the two protrusions 9111 are connected across the both sides of the first water passing hole 9112. The protrusions 9111 can be integrally formed with the assembly part 91a, so that the preparation of the protrusions 9111 is simple and basically does not increase the preparation cost of the assembly part 91a.

For example, please refer to FIG. 71. In the direction shown in the figure, a protrusion 9111 is provided upward along the third direction Z. The protrusion 9111 extends from the edge of the assembly part 91a in the second direction Y to the side of the first water passing hole 9112. Please refer to FIG. 78 and FIG. 79. The protrusion 9111 extends upward and in a direction close to the main body 920. Here, the protrusion 9111 is configured to prevent residual water and other liquids from moving backward along the first direction X, so as to prevent residual water from leaking to the rear side. Moreover, due to the blocking and guiding of the first protrusion 9111, residual water and other liquids can move along the first protrusion 9111 to the first water passing hole 9112 in the middle, and drop down through the first water passing hole 9112. Therefore, residual water will no longer leak to the rear side close to the first side, so as to reduce the accumulation of residual water on the rear side, and improve the water accumulation situation on the bearing part 940 or the ground.

Here, please refer to FIG. 76 and FIG. 77. The main body 920 is provided with a suction port 921, which is connected to a suction source (not shown) of the main body 920 for the passage of suction airflow. The suction airflow formed by the suction source is configured to suck dust and other substances at the roller brush assembly 930 through the suction port 921. If the aforementioned protrusion 9111 is provided at the position corresponding to the suction port 921, it may interfere with the outer wall of the suction port 921. Therefore, in the embodiment of the present disclosure, the assembly part 91a is correspondingly provided with the first water passing hole 9112 corresponding to the suction port 921 provided in the middle, and the first water passing hole 9112 simultaneously achieve the technical effects of avoiding the suction port 921 and guiding the residual water to move forward along the cleaning assembly 910 and leave the assembly gap. Of course, it is understood that in other embodiments, the suction port 921 can be provided in other positions, and correspondingly, the first water passing hole 9112 can be provided in other positions, that is, the first water passing hole 9112 is not limited to being provided in the middle area of the assembly part 91a. At the same time, in other embodiments, the suction port 921 may not be provided on the side of the main body 920 near the cleaning assembly 910, but in this case, if the suction port 921 is far away from the to-be-cleaned surface, it may lead to poor dust removal effect.

Here, if the main body 920 does not have other structures that may interference with protrusions 9111 on the side close to the cleaning assembly 910, the first water passing hole 9112 may not be provided, but the protrusions 9111 may be made to penetrate the assembly part 91a along the second direction Y, so as to prevent residual water from moving to the rear side. This embodiment is not limited thereto.

For example, in some examples, the first water passing hole 9112 is not provided, and the protrusion 9111 extends from one end of the assembly part 91a to the other end 100 along the second direction Y, that is, the protrusion 9111 extends along the second direction Y over the entire assembly part 91a to block the movement path of residual water to the rear side. With the blocking by the protrusion 9111, the residual water may move forward and/or to both sides along the second direction Y, so that the residual water may not accumulate in the area behind the protrusion 9111. Preferably, the assembly part 91a gradually slopes toward the to-be-cleaned surface along the first direction X, which can advantageously guide the residual water to flow toward the roller brush side.

Here, the first water passing hole 9112 penetrates the assembly part 91a, and on the side of the first water passing hole 9112 away from the main body 920, the assembly part 91a and the cleaning part 91b extend towards the second side, that is, towards the front side, and gradually incline towards the to-be-cleaned surface along the first direction X. Therefore, the assembly part 91a and the cleaning part 91b are used as a guide to guide the residual water that drops down towards the front side. The liquid flowing down from the first water passing hole 9112 can be attached to the wall and flow towards the roller brush side along the outer wall of the assembly part 91a. Of course, it is understood that in other embodiments, a guide wall that gradually inclines towards the to-be-cleaned surface along the first direction X can be additionally provided to form the guide part, or the guide part may not be specifically provided. This embodiment does not constitute an undue limitation.

In some embodiments, with reference to FIG. 73 and FIG. 74 again, the assembly part 91a is further provided with a second water passing hole 9113, which is located on the second side of the protrusion 9111, that is, in the first direction X. The second water passing hole 9113 is located on the front side of the protrusion 9111. Here, six sections of the second water passing hole 9113 are provided at intervals, but it is understood that this is not limited in other embodiments. The number of the second water passing ports 9113 can be set according to actual needs, and the second water passing ports can be connected to each other, that is, they do not have to be provided at intervals.

Here, the second water passing hole 9113 is closer to the front side than the first water passing hole 9112, which can be configured to allow residual water to flow through, so that the residual water can flow to the front side area earlier and reduce the leakage of residual water to the rear side. With reference to FIG. 78 and FIG. 79, some of the residual water in the assembly gap flows down through the second water passing hole 9113, while the remaining part of the residual water continues to flow backward and may be blocked by the protrusion 9111, and may not continue to flow backward, and has to flow down from the first water passing hole 9112 (see FIG. 76 and FIG. 77) or the second water passing hole 9113. After that, the residual water can flow in the direction of the front side under the guiding by the guide part.

Here, please continue to refer to FIG. 79. The assembly part 91a is provided with a cooperating part, which is generally stepped and has a first wall surface 9114 extending along the third direction Z, a second wall surface 9115 extending along the first direction X, and a third wall surface 9116 extending along the third direction Z. The first wall surface 9114, the second wall surface 9115, and the third wall surface 9116 are connected in sequence. Correspondingly, the main body 920 is provided with a connecting part 922, which has a protruding part protruding towards the front side of the first direction X. The cooperating part is provided correspondingly to the connecting part 922 for mutual cooperation to implement assembly. For example, when the assembly part 91a and the main body 920 cooperates with each other, the protruding part can be attached with the second wall surface 9115 and the third wall surface 9116. Here, the cooperating part corresponds to the second water passing hole 9113, so that the second water passing hole 9113 can be used to pass water, and be used as a mold piercing hole when the assembly part 91a and its cooperating part are made, so as to facilitate the preparation of the cooperating part. Of course, it is understood that the structure of the cooperating part and the connecting part 922 is not limited to the above, and this embodiment does not constitute an undue limitation on it.

In some embodiments, the assembly part 91a is inclined towards the direction of the roller brush assembly 930.

For example, with reference to FIG. 79, the assembly part 91a gradually inclines towards the to-be-cleaned surface, that is, away from the main body 920, in forward along the first direction X. With the assembly part 91a inclined towards the front side, it is possible to reduce the leakage of residual water towards the rear side. At the same time, after leaving the first water passing hole 9112 and/or the second water passing hole 9113, the residual water is more likely to move towards the front side, so as to reduce the leakage of residual water towards the rear side.

Please refer to FIG. 80, description is made below with the cleaning device placed on the bearing part 940 as an example.

In connection with the aforementioned FIGS. 76 to 79, with the protrusions 9111 provided, residual water may be prevented from flowing back easily. Furthermore, with the first water passing hole 9112 and/or the second water passing hole 9113 provided, it is possible to guide the residual water to flow downward as early as possible, and the residual water is closer to the roller brush assembly 930 on the second side when flowing downward.

Here, the bearing part 940 is provided with a cleaning area 942 (see FIG. 70 and FIG. 80) corresponding to the roller brush assembly 930. When the first water passing hole 9112 and the second water passing hole 9113 are not provided, the residual water cannot move backward by the blocking of the protrusion 9111. At this time, the residual water may move toward the cleaning area 942 and the opposite sides of the second direction Y, so as to avoid water stains from forming in the middle of the bearing part 940. When the first water passing hole 9112 and/or the second water passing hole 9113 are provided, the residual water can flow downward through the first water passing hole 9112 and/or the second water passing hole 9113 and then be guided to the cleaning area 942. It can be seen that the cleaning device provided by the embodiment of the present disclosure may improve the user's experience and solve the problem of water accumulation in the middle of the bearing part 940.

In addition, it is understood that in the above embodiment, the second water passing hole 9113 is not located at the A′ section, but in other embodiments, the second water passing hole 9113 can be located at the A′ section, that is, the middle section of the assembly part 91a. There is no limitation thereon in the present disclosure.

In some embodiments, the assembly part 91a is provided with a first water passing hole 9112, and the water blocking protrusions 9111 are disposed adjacent to both sides of the first water passing hole 9112 along the second direction Y. For example, the first water passing hole 9112 is disposed in the middle of the assembly part 91a along the second direction Y, and the two water blocking protrusions 9111 are disposed along the second direction Y on both sides of the first water passing hole 9112 and extend to the edge of the assembly part 91a in the second direction Y.

In some embodiments, the first water passing hole 9112 is provided with a guide part on one side of the third direction Z, which may extend to be close to the second side. For example, the first water passing hole 9112 penetrates the assembly part 91a, and the guide part is formed on the wall surface of the cleaning assembly 910 on one side of the third direction Z. It is understood that the guide part and the free end of the cleaning part 91b are located on the same side of the assembly part 91a in the third direction Z.

In some embodiments, the assembly part 91a is further provided with a second water passing hole 9113, which is located on the second side of the water blocking protrusion 9111.
