Cleaning devices such as floor scrubbers, wet vacuum cleaners, mopping machines, etc. are generally provided with a dirt treatment apparatus, a floor brush, a power apparatus, etc. The floor brush is internally provided with a gas suction channel, the dirt treatment apparatus is internally provided with a suction channel, and the gas suction channel is in communication with the suction channel. When the power apparatus is started, an interior of the dirt treatment apparatus is in a negative pressure state; sewage on the floor enters the suction channel through the gas suction channel of the floor brush; gas is discharged out of the dirt treatment apparatus through an air outlet of the dirt treatment apparatus; and liquid substances and solid substances are collected in the dirt treatment apparatus. The existing dirt treatment apparatus can only separate gas from solid and liquid, and cannot separate solid and liquid, which is inconvenient for a user to clean. The dirt treatment apparatus provided in some embodiments of the disclosure can separate three-phase substances entering the dirt treatment apparatus, facilitating cleaning by the user. Hereinafter, the dirt treatment apparatus provided in some embodiments of the disclosure will be described in detail.

Referring to FIGS. 1-3, some embodiments of the disclosure provide a separation apparatus 12; the separation apparatus 12 is disposed in a box body 11 (e.g., assembled in the box body 11), and the box body 11 is provided with a suction channel 111 allowing for communication between an interior and an exterior of the box body 11, and an air outlet 112. The separation apparatus 12 includes a main body member 121 and a blocking member 124. The main body member 121 is provided in the box body 11, and the main body member and an inner wall of the box body 11 define a separation channel in communication between the suction channel 111 and the air outlet 112. The blocking member 124 is fitted on the main body member 121 and blocks a flow path of all airflows flowing from the suction channel 111 to the air outlet 112. After colliding with the blocking member 124, all airflows flowing out of the suction channel 111 are diverted to flow into the separation channel, and are subjected to one-stage or multi-stage separation operation and then flow out through the air outlet 112.

During actual operation of the separation apparatus 12, sewage carried by the airflow flows towards the blocking member 124 through the suction channel 111, and then collides with the blocking member 124, and is diverted under a blocking of the blocking member 124. Due to different motion inertia of solid-liquid-gas three-phase substances, the three phases will be separated after diversion, thereby increasing a separation efficiency of the three phases. After simultaneous diversion, the three phases enter the separation channel, and are subjected to one-stage or multi-stage separation in the separation channel and then is substantially separated thoroughly, and in this case, the airflow flowing out of the air outlet 112 is substantially free of solid-liquid two phases.

Compared with the related art, by the arrangement of the blocking member 124, the airflow cannot directly flow to the air outlet 112, so that the airflow is subjected to active three-phase separation after collision, thereby increasing the separation efficiency; and the airflow is diverted to enter the separation channel after colliding with the blocking member 124, and flows out through the air outlet 112 after being further subjected to one-stage or multi-stage separation in the separation channel. In this way, a separation path for solid-liquid-gas three-phase substances is lengthened, so that the airflow basically achieves three-phase separation when reaching the air outlet 112, and a good separation effect can also be achieved without providing a consumable such as an HEPA filter assembly at the air outlet 112, which not only has a low separation cost, but also can avoid the problem of low separation efficiency caused by clogging of the filter assembly, thereby ensuring the suction effect.

In a use state, the air outlet 112 is located above the separation apparatus 12.

Referring to FIG. 2, in some embodiments, a surface of the blocking member 124 facing the suction channel 111 is defined as a blocking surface, the blocking surface is arranged eccentrically with respect to a central axis of the suction channel 111.

The blocking surface and the suction channel 111 are eccentrically arranged, and the airflow entering a flow guide cavity 1213 through the suction channel 111 mainly collides with a part of the blocking surface close to the edge. In this case, the airflow entering the flow guide cavity 1213 and an airflow flowing out of the flow guide cavity 1213 mainly flow in two different regions, which reduces an interference of an incoming airflow on a flow field where an outgoing airflow is located. Furthermore, due to the eccentric arrangement, the airflow has a certain centrifugal force, and under an action of the centrifugal force, the airflow can accelerate to flow out of the flow guide cavity 1213 and enter the separation channel, facilitating increase of the whole separation efficiency.

The blocking surface is arranged eccentrically with respect to the central axis of the suction channel 111 means that a central line of the blocking surface is located on a side of a central axis of the suction channel 111, and the two are arranged on different axes.

Further, the blocking surface is a cambered surface protruding in a direction facing away from the suction channel 111. In this case, the blocking surface is set as the cambered surface, so that the power loss of the airflow is reduced, and the air pressure loss can be further reduced, thereby helping to reduce the requirement for a high air pressure of a blower. Specifically, the blocking surface is a hemispherical surface.

In some embodiments, the separation apparatus 12 further includes a first filter member 122, in which the first filter member 122 is arranged in the separation channel and located downstream of a diverted airflow formed after colliding with the blocking member 124.

During actual operation, after the airflow collides with the blocking member 124, the airflow is diverted to move obliquely downwards, and during movement, gas substances in actively separated three phases flow to the air outlet 112 under a suction force of the blower, while liquid substances and solid substances continue to move towards the first filter member 122; in which most of the solid substances remain on the first filter member 122, the liquid substances flow to a bottom of the box body 11 under its own gravity after passing through the first filter member 122, so as to achieve primary separation operation of the airflow in the separation channel. After the primary separation operation, the gas substances and a small portion of the liquid substances and a small portion of the solid substances continue to move along the separation channel under the action of the suction force of the blower, and continue to be separated.

At this time, the first filter member 122 is able to separate the liquid and the solid, and is able to retain at least a part of the solid, so that effective separation of the solid and the liquid can be realized, and it is also convenient for a user to clean the box body 11 subsequently.

Referring to FIGS. 2 and 3, in some embodiments, the blocking member 124 is disposed in the main body member 121 (e.g., assembled in the main body member 121), and divides the main body member 121 to form a flow guide cavity 1213 in communication with the suction channel 111. The main body member 121 is provided with a lateral notch 1211 in communication between the flow guide cavity 1213 and the separation channel, and the lateral notch 1211 is located on a flow path in which the diverted airflow formed after colliding with the blocking member 124 flows to the first filter member 122.

During actual operation, the airflow enters the flow guide cavity 1213 through the suction channel 111, and flows towards the blocking member 124 to collide with the blocking member 124; and under a collision reaction force of the blocking member 124, the airflow moves towards the lateral notch 1211, and enters the separation channel through the lateral notch 1211. In this case, by providing the flow guide cavity 1213 and the lateral notch 1211, it can be ensured that the diverted airflow enters the separation channel smoothly, and the whole structure is compact.

In some embodiments, the separation apparatus 12 includes a second filter member 123, and the second filter member 123 is provided in the separation channel and located in a flow path in which the airflow separated after flowing through the first filter member 122 flows to the air outlet 112.

During actual operation, under the action of the suction force of the blower, when the diverted airflow moves towards the first filter member 122, most of the solid substances and the liquid substances are separated from the gas substances under the action of motion inertia and move towards the first filter member 122, thereby achieving solid-liquid separation by the first filter member 122, and thus most of the solid substances and the liquid substances are separated. While a small portion of solid substances and a small portion of liquid substances carried by the gas substances flow along the separation channel towards the second filter member 123, the gas substances flow toward the air outlet 112 under the filtration of the second filter member 123, and a portion of solid substances and a small portion of liquid substanc”s ar' adhered to the second filter member 123 and move towards the downward first filter member 122 under an action of gravity; and finally the solid substances are retained on the first filter member 122, the liquid substances are collected at a bottom of the box body 11, and the gas substances are discharged out of the box body 11, thereby realizing the separation of gas, liquid and solid three-phase substances.

In this case, the degree of separation of the three-phase substances can be further increased by providing the second filter member 123, thereby increasing the separation efficiency. In this case, it is unnecessary to additionally provide consumables such as an HEPA filter assembly at the air outlet 112, resulting in a low separation cost.

Referring to FIGS. 2 and 3, in some embodiments, the blocking member 124 further divides the main body member 121 to form a ventilation cavity 1212 in communication with the air outlet 112, and the second filter member 123 covers an outer periphery of the ventilation cavity 1212.

During actual operation, the gas separated by the second filter member 123 is finally returned to the air outlet 112 through the ventilation cavity 1212. In this case, the ventilation cavity 1212 in communication with the air outlet 112 is arranged in the main body member 121, which not only makes full use of an inner space of the main body member 121 to lengthen a separation path, but also forms a hidden flow channel, so that an overall structure is more compact.

In some embodiments, the ventilation cavity 1212 is located below the air outlet 112 in the direction of gravity. In this case, the ventilation cavity 1212 and the air outlet 112 have the shortest flow path and are in direct communication with each other, which facilitates reduction of the air pressure loss.

The first filter member 122 may be a filter member having a relatively large filtration pore diameter, such as a filter screen and a filter plate. The second filter member 123 may be a filter member having a relatively small filter pore diameter, such as a filter mesh, filter cotton and filter cloth. A filtration pore diameter of the first filter member 122 is greater than a filtration pore diameter of the second filter member 123. The specific pore diameters are not limited. In some embodiments, the first filter member 122 can retain most solid substances, and the second filter member 123 is only limited to allow for flowing of gas substances.

In a specific example, the main body member 121 has a first end and a second end, the first end is located above the second end in the direction of the airflow path and is connected with the box body 11, and the first end has the ventilation cavity 1212 in communication with the air outlet 11. The first filter member 122 is disposed on the second end (e.g., assembled on the second end). In particular, the first end is located above (including directly above and obliquely above) the second end in the orientation as shown in the figures.

Referring to FIGS. 2 and 3, in some embodiments, the separation apparatus 12 further includes a partition plate 125, the partition plate 125 is disposed in the separation channel (e.g., assembled in the separation channel), and divides a part of the separation channel in an airflow flowing direction to form at least two layers of separation flow channels; and a middle flow channel S3 is defined between the other part of the separation channel and the main body member 121, and the separation flow channels of all the layers are in communication with each other through the middle flow channel S3.

During actual operation, the airflow flows between various layers of separation flow channels through the middle flow channel S3, and continuously rotates along the main body member 121 and diverts the flow direction in the flowing process, to form a spiral-like flow path. In the diverting process, under an action of centrifugal force, liquid substances and solid substances in the airflow are thrown towards the inner wall of the box body 11 or stay on the partition plate 125 (because the flowability of the solid substances is poorer than the flowability of the liquid substances, the solid substances generally stay on the partition plate 125, and the liquid substances flow to the bottom of the box body 11 along a side wall of the box body 11); while the gas substances continue to flow along the various flow channels, and the solid substances and liquid substances in the airflow are further separated, improving the separation effect.

In this case, multiple layers of separation flow channels are formed by the partition plate 125, so that the length of the airflow separation path is greatly lengthened, the separation effect is improved, and the separation effect of the solid substances and the liquid substances is improved at the same time. When the dirt treatment apparatus 10 in the embodiment is actually used, the filter assembly arranged at the air outlet 112 can be omitted, so that the costs of consumables are greatly reduced, and the middle flow channel S3 is in communication with the separation flow channels at various layers, so that the requirement for a high wind pressure of the blower is low.

Specifically, the partition plate 125 is disposed on one side of the outer periphery of the main body member 121 (e.g., assembled on one side of the outer periphery), and at least two layers of separation flow channels are located on an eccentric side of the blocking member 125. The other side of the outer periphery of the main body member 121 and the inner wall of the box body 11 form the middle flow channel S3, and the middle flow channel S3 passes through the axial direction of the main body member 121.

Referring to FIG. 2, in some embodiments, the at least two layers of separation flow channels include an upper-layer separation flow channel S2 and a lower-layer separation flow channel S1, the first filter member 122 is provided in the lower-layer separation flow channel S1, and the second filter member 122 is provided in the upper-layer separation flow channel S2.

In this case, the first filter member 122 is provided in the lower-layer separation flow channel S1, and the second filter member 122 is provided in the upper-layer separation flow channel S2, so that the three-phase substances in the airflow are separated by making full use of the length of the separation channel.

It can be understood that the at least two layers of separation flow channels can further include at least one layer of middle-layer separation flow channel located between the upper-layer separation flow channel S2 and the lower-layer separation flow channel S1, which is not specifically limited.

Specifically, the second filter member 123, the lateral notch 1211 and the partition plate 125 are located on the same side of the outer periphery of the main body member 121, so as to form a separation flow channel that facilitates diversion of the airflow. “The second filter member 123, the lateral notch 1211 and the partition plate 125 are located on the same side of the outer periphery of the main body member 121” means that, when viewed in the orientation as shown in the figures, in a plane perpendicular to an axial direction of the main body member 121, projections of the second filter member 123, the lateral notch 1211 and a connection position between the partition plate 125 and the main body member 121 on the plane at least partially overlap.

In other embodiments, the separation channel may also be other spiral flow channels formed by spirally arranging a separation member around the axial direction of the main body member 121, and it's just that the blower requires high wind pressure. In some embodiments of the disclosure, the specific construction form of the separation channel is not limited.

Referring to FIG. 2, in some embodiments, a gap for liquid circulation is provided both between the partition plate 125 and a side wall of the box body 11, and the first filter member 122 and the side wall of the box body 11. In this case, the liquid substances adhered to the side wall of the box body 11 when moving through the separation channel can directly flow to the bottom of the box body 11 through the described gaps under the action of gravity, thereby facilitating the recovery of the liquid substances. Of course, in other embodiments, the liquid substances adhered to the side wall of the box body 11 may also fall on the bottom of the box body 11 after passing through the first filter member 122, which is not limited to the manners above.

In some embodiments, the suction channel 111 is a straight channel in the gravity direction. In this way, the power loss during flowing of the airflow can be reduced, and the air pressure loss can be reduced.

By the arrangement of the blocking member 124, the separation apparatus 12 makes the airflow not to directly flow to the air outlet 112, so that not only active three-phase separation of the airflow after collision is strengthened, thereby increasing the separation efficiency; but also the airflow is diverted to enter the separation channel after colliding with the blocking member 124, and flows out through the air outlet 112 after being further subjected to one-stage or multi-stage separation in the separation channel. In this way, a solid-liquid-gas three-phase separation path is lengthened, so that the airflow basically achieves three-phase separation when reaching the air outlet 112, and a good separation effect can also be achieved without providing a consumable such as an HEPA filter assembly at the air outlet 112, which not only has a low separation cost, but also can avoid the problem of low separation efficiency caused by clogging of the filter assembly, thereby ensuring the suction effect.

In addition, some embodiments of the disclosure further provide a dirt treatment apparatus 10. Referring to FIG. 1 to FIG. 3, the dirt treatment apparatus 10 includes a box body 11 and the separation apparatus 12 provided in any one of the embodiments above. The box body 11 is provided with a suction channel 111 allowing for communication between the interior and the exterior of the box body 11, and an air outlet 112. The dirt treatment apparatus 10 includes the described separation apparatus 12, and thus the dirt treatment apparatus includes the beneficial effects of the separation apparatus 12, which will not be repeated here.

Referring to FIG. 3, in some embodiments, the dirt treatment apparatus 10 further includes a detection apparatus 13, in which the detection apparatus 13 is provided in the box body 11 and used for acquiring a content characteristic of a solid substance in separated substances obtained after primary separation.

During actual operation, after acquiring the content characteristic of a solid substance in separated substances obtained after primary separation, the detection apparatus 13 can determine the content of the separated solid substance after the primary separation according to the content characteristic. When there is a solid substance or the solid substance exceeds the standard, it indicates that the dirty degree on the floor is heavy, and it is necessary to increase rotational speeds of a blower in a power apparatus 40 and a rolling brush motor in a floor brush 30, so as to increase the cleaning intensity. When there is no solid substance or the solid substance does not exceed the standard, it indicates that the dirty degree on the floor is light, and the rotational speeds of the blower in the power apparatus 40 and the rolling brush motor in the floor brush 30 can be reduced, so as to save energy and power.

In some embodiments of the disclosure, the detection apparatus 13 includes a gravity sensor, and the content characteristic is a weight signal which is generated by the solid substance on the first filter member 122 and is acquired by the gravity sensor. Alternatively, the detection apparatus 13 includes an infrared sensor, and the content characteristic is an infrared signal which is acquired by the infrared sensor and reflected by the solid substance on the first filter member 122.

During actual operation, the content characteristic of the solid substance on the first filter member 122 may be acquired by the gravity sensor or the infrared sensor. Specifically, the gravity sensor is provided on the first filter member 122, and when a solid substance is retained on the first filter member 122, the solid substance falls on the gravity sensor, and when gravity of the solid substance acts on the gravity sensor, the gravity sensor acquires a gravity signal of the solid substance. To be specific, the infrared sensor is mounted on the inner wall of the box body 11 and is arranged towards the first filter member 122; when a solid substance exists on the first filter member 122, infrared light generated by the infrared sensor is reflected by the solid substance and then received by the infrared sensor again, and in this case, the content characteristic of the solid substance is an infrared signal generated by the solid substance.

In other embodiments, the detection apparatus 13 may also acquire the content characteristic of the solid substance by a pressure sensor, an image sensor, or the like. The content characteristic may be used to characterize the presence or absence of solid substance on the first filter member 122.

Certainly, the detection apparatus 13 may also be provided at other positions of the box body 11, for example, at the bottom of the box body 11. In this case, the infrared sensor may be used to acquire the content characteristic of solid in sewage mixed with liquid or solid in the box body 11, and according to this, the dirty degree on the floor is determined.

Referring to FIG. 3, in some embodiments, the dirt treatment apparatus 10 further includes an electrode assembly 14, in which the electrode assembly 14 includes two electrodes 141, and each of the electrodes 141 is disposed on the box body 11 (e.g., assembled on the box body 11) and is at least partially inserted into the box body 11. When a liquid level in the box body 11 rises to submerge at least a part of the two electrodes 141, the two electrodes 141 are conducted.

During actual operation, when the two electrodes 141 are conducted, it indicates that the water level in the box body 11 is too high, and an operator is reminded to pour the sewage in the dirt treatment apparatus 10. When there is a little sewage in the box body 11, both the two electrodes 141 are away from the water surface, which indicates that the volume of the dirt treatment apparatus 10 is sufficient and dirt removal work can be performed continuously.

In some embodiments, the electrodes 141 are located in the separation channel and extend along the axial direction of the main body member 121, thereby saving the mounting space.

Of course, the number of the electrodes 141 included in the electrode assembly 14 may also be greater than two, which is not specifically limited.

Of course, the cleaning device can further include other configurations, which are not specifically limited. Referring to FIG. 6, it is a logic control diagram when the cleaning device is a floor scrubber according to some embodiments. The specific control process is shown in the figure, and will not be repeated herein.

According to some embodiments provided in the disclosure, referring to FIG. 7, some embodiments of the disclosure further provide a control method for a cleaning device, including following operations S1 to S4:

• • At S1, acquiring a content characteristic of a solid substance in separated substances obtained after primary separation by a dirt treatment apparatus 10 in the cleaning device;
  • At S2, determining whether a solid substance is newly added in the dirt treatment apparatus 10 according to the content characteristic of the solid substance;
  • At S3, if so, entering a quick-suction mode; and in the quick-suction mode, a rolling brush motor and a blower of the cleaning device operating at a corresponding first rotational speed.

The dirt treatment apparatus 10 in the cleaning device may be but not limited to, including the main body member 121, the blocking member 124, the first filter member 122 and the detection apparatus 13 in the embodiments above. For the specific arrangements of the main body member 121, the blocking member 124, the first filter member 122 and the detection apparatus 13, reference is made to the illustration above, which will not be repeated here. In addition, the cleaning device further includes the floor brush 30 and the power apparatus 40, in which the floor brush 30 includes a rolling brush and a rolling brush motor for driving the rolling brush to rotate, the power apparatus 40 includes a blower, and the blower generates a negative pressure in the dirt treatment apparatus 10. When the rolling brush rotates, the floor can be wiped, and under an action of the negative pressure, sewage from the rolling brush and the floor enters the suction channel 111 of the dirt treatment apparatus 10 through the gas suction channel 31 in the floor brush 30, and finally enters the dirt treatment apparatus 10. The floor brush 30 further includes a squeegee for scraping the sewage absorbed by the rolling brush and the adhered solid waste to the floor and suctioning into the gas suction channel 31. Specific configurations of the floor brush 30 and the power apparatus 40 will not be elaborated herein.

In practical use, the detection apparatus 13 may be used to acquire the content characteristic of the solid substance on the first filter member 122, and can determine whether the solid substance is newly added on the first filter member 122 according to the content characteristic. When a solid substance is newly added, it indicates that the dirty degree on the floor is heavy, and solid waste with large particles is present, and it is necessary to increase the rotational speeds of the blower in the power apparatus 40 and the rolling brush motor in the floor brush 30, so as to increase the cleaning intensity; and then, a quick-suction mode is entered. In the quick-suction mode, the rolling brush motor and the blower of the cleaning device operate at a corresponding first rotational speed.

Specifically, whether a solid substance is newly added is determined according to a plurality of content characteristics successively acquired in a first time period. For example, the content characteristic is a gravity signal acquired by a gravity sensor. When a plurality of continuous gravity signals indicate that the gravity gradually increases, it indicates that a solid substance is newly added. If the gravity does not increase, it represents that no solid substance is newly added.

The “first rotational speed” refers to a speed greater than a rotational speed in the intelligent mode mentioned subsequently. “A solid substance is newly added” includes a change in solid substance content from nothing to something.

In specific embodiments, after operation S3, the method further includes:

S4, if not, entering an intelligent mode; and in the intelligent mode, adjusting rotational speeds of the rolling brush motor and the blower according to cleaning characteristics acquired by a stain detection system, in which the rotational speeds of the rolling brush motor and the blower are both less than the corresponding first rotational speed.

In this embodiment, when no solid is newly added in the dirt treatment apparatus 10, it indicates that the dirty degree on the floor has been alleviated and is relatively clean, and the rotational speeds of the rolling brush motor and the blower can be reduced, and then the intelligent mode is entered. In the intelligent mode, the rotational speeds of the rolling brush motor and the blower are adjusted according to the cleaning characteristics acquired by the stain detection system. In the intelligent mode, the rotational speeds of the rolling brush motor and the blower are both less than the corresponding first rotational speed. Power can be saved, and the operating time of the cleaning device can be prolonged.

In this embodiment, the machine body 20 of the cleaning device has a transition channel 21 allowing for connecting the suction channel 111 and the gas suction channel 31, and the stain detection system includes an infrared detection apparatus 13 arranged in the transition channel 21. The infrared detection apparatus 13 is used to detect the cleaning characteristics of substances flowing through the transition channel 21, to characterize the cleanliness of circulating substances. The cleaning characteristics may be the number of electrical signals or the intensity of electrical signals, caused by the intensity of infrared light received by the infrared detection apparatus 13 and reflected from solid substances in the sewage.

When the cleaning characteristics indicate that the cleanliness of circulating substances flowing through the transition channel 21 is high, the rotational speeds of the rolling brush motor and the blower are reduced, so as to save energy and power and prolong the endurance of the cleaning device. When the cleaning characteristics indicate that the cleanliness of circulating substances flowing through the transition channel 21 is low, the rotational speeds of the rolling brush motor and the blower are increased, so as to enhance the cleaning intensity.
