In an embodiment of the disclosure, the cleaning device 1000 includes, but is not limited to, a cleaning machine, a vacuum cleaner, a sweeping robot and other devices. Taking the cleaning machine shown in FIG. 1 as the cleaning device 1000 as an example, a floor brush 100 in contact with a to-be-cleaned surface and a machine body 200 connected with the floor brush 100 are included. The machine body 200 is provided with a functional unit such as a suction system and a control system, which cooperates with the floor brush 100 to complete a cleaning operation. For example, when the cleaning machine performs the cleaning operation, a rolling brush 110 on the floor brush 100 realizes the function of cleaning the to-be-cleaned surface by rolling. The suction system works to generate negative pressure, and the function of collecting dirt is realized through the floor brush 100. The to-be-cleaned surface includes a floor, a carpet surface, a sofa surface, etc. For simple description, explanation is made below by taking the floor as an example.

Referring to FIGS. 2 to 4, the floor brush 100 includes the rolling brush 110 rotatable in a preset direction and a cover component 120 detachably connected with the floor brush 100, and the cover component 120 may cover part of the rolling brush 110. A suction nozzle component 130 includes a panel 131 and a suction port 132 located in the panel 131 and communicated with a suction source. A dirt suction channel communicated with the suction port 132 is arranged inside the machine body 200. The cleaning device 1000 may clean the dirt on the floor through the rolling brush 110 and suck the dirt on the floor through the suction port 132, and the sucked dirt enters the dirt suction channel through the suction port 132. The suction nozzle component 130 is located below the cover component 120, and the suction nozzle component 130 is detachably connected with the floor brush 100. The suction nozzle component 130 in the disclosure is detachably connected with the floor brush 100, so that the suction nozzle component 130 is able to be disassembled from the floor brush 100 for cleaning, and it is not necessary to move the whole floor brush 100 when the suction nozzle component 130 is cleaned, thus bringing convenience for the user to operate, and liquid is able to be prevented from infiltrating into the floor brush 100 and damaging a device such as a water pump and a rolling brush motor inside the floor brush 100 when the floor brush 100 is directly cleaned.

As shown in FIG. 3, the panel 131 extends in an axial direction of the rolling brush 110 and is located behind the rolling brush 110, and a length of the panel 131 is consistent with a length of the rolling brush 110. When the rolling brush 110 rotates, sewage on the rolling brush 110 may splash onto the panel 131. The panel 131 is arranged to extend in an axial direction of the rolling brush 110 and the length of the panel 131 is enabled to be consistent with the length of the rolling brush 110, so that most of the sewage splashed from the rolling brush 110 is able to be located on the panel 131. At this time, the panel 131 is disassembled so that most of stains on the floor brush 100 is able to be cleaned, thus avoiding, as the panel 131 is too much small, many stains still on the floor brush 100 after the panel 131 is disassembled for cleaning.

In one embodiment implementation, as shown in FIG. 3, the suction nozzle component 130 is connected with the cover component 120, and by disassembling the cover component 120, the suction nozzle component 130 connected with the cover component 120 is able to be disassembled without the need of being disassembled twice, so that the disassembly efficiency is improved, and the operation is simple and convenient. The suction nozzle component 130 and the cover component 120 are able to be detachably connected or integrally formed, which is not specifically limited here. The detachable connection mode is able to be a general technology such as clamping connection and bolted connection, which is not specifically limited here. In other implementations, the suction nozzle component 130 has no connection relationship with the cover component 120. The cover component 120 is able to be disassembled first, and then the suction nozzle component 130 is disassembled.

As shown in FIG. 4, the cover component 120 is provided with a latch mechanism 121. The latch mechanism 121 includes a spring, a lock body 1211 and a user operating unit 1212. The user is able to drive the user operating unit 1212 to enable the lock body 1211 to move from a first position to a second position under an action of the spring. When the lock body 1211 is in the first position, the lock body 1211 is clamped in a groove 101 of the floor brush 100, and when the lock body 1211 is in the second position, the lock body 1211 is far away from the groove 101 of the floor brush 100, so that the cover component 120 is far away from the floor brush 100. The user operating unit 1212 is located outside the cover component 120, which brings convenience for the user to operate. In the implementation, the lock body 1211 extends in an axial direction of the rolling brush 110, two grooves 101 are respectively formed in both sides of the floor brush 100 to match the lock body 1211 in position, and the lock body 1211 may move in an axial direction of the rolling brush 110 under an action of the spring. In another implementation, the lock body 1211 extends in a radical direction of the rolling brush 110. The groove 101 is arranged in the floor brush 100, located above a middle part of the floor brush 110, and matched with the lock body 1211 in position. The lock body 1211 may move in an axial direction of the rolling brush 110 under an action of the spring. At this time, the user only needs to press the user operating unit 1212, so that the cover component 120 is able to be disassembled without using a tool, and the operation is simple and convenient.

As shown in FIGS. 3 to 5, in one embodiment implementation, the floor brush 100 further includes a liquid spraying component 140 for applying the liquid to the rolling brush 110, and the liquid spraying component 140 is located between the cover component 120 and the suction nozzle component 130. It is to be easily conceived of that the liquid spraying component 140 is also apply the liquid to the to-be-cleaned surface, or simultaneously apply the liquid to the rolling brush 110 and the to-be-cleaned surface. In the implementation, the liquid spraying component 140 is able to be detachably connected with the floor brush 100, and the liquid spraying component 140 is respectively connected with the cover component 120 and the suction nozzle component 130. When the cover component 120 is disassembled, the liquid spraying component 140 is also disassembled, which facilitates cleaning and replacement of the liquid spraying component 140. Liquid spraying components 140 with different apertures is able to be designed as accessories, thus bringing convenience for the user to replace the liquid spraying component 140.

As shown in FIGS. 6 and 7, in one embodiment implementation, the liquid spraying component 140 includes a plurality of liquid outlet holes 141 and a plurality of guide grooves 142. The number of the guide grooves 142 is consistent with the number of the liquid outlet holes 141. The plurality of liquid outlet holes 141 are respectively located in middle parts of the plurality of guide grooves 142. Each guide groove of the plurality of guide grooves 142 includes a plurality of inclined planes 1421, and is in a shape of a trumpet expanding outwards with corresponding liquid outlet hole of the plurality of liquid outlet holes 141 as a center. Herein, the inclined plane 1421, below the corresponding liquid outlet hole of the plurality of liquid outlet holes 141, of the each guide groove of the plurality of guide grooves 142 is an arc surface. The arc surface is an arc surface with a lower middle part and two higher ends. That is, a part right below the liquid outlet hole of the plurality of liquid outlet holes 141 is the lowest part of the inclined plane 1421, and gradually rises to both ends. The arc-surface inclined plane 1421 may improve the uniformity of the output liquid, so as to uniformly wet the rolling brush 110, thereby efficiently completing floor cleaning. In the implementation, the plurality of liquid outlet holes 141 are respectively located in the centers of the plurality of guide grooves 142, which facilitates uniform distribution of the sprayed liquid and enables the liquid sprayed out of both sides of the liquid outlet holes 141 to simultaneously reach the rolling brush 110. In other implementations, the liquid outlet hole of the plurality of liquid outlet holes 141 does not need to be located in the center, and requirements is able to be met by a slight shift in any direction. The trumpet-shaped guide groove 142 enables water sprayed out of the liquid outlet hole of the plurality of liquid outlet holes 141 to flow along the inclined plane 1421 of the guide groove 142, and finally flow to the rolling brush 110, thus increasing the water dispersibility. The liquid outlet hole of the plurality of liquid outlet holes 141 is arranged in the guide groove 142, which may effectively prevent the liquid outlet hole of the plurality of liquid outlet holes 141 from being blocked. When too much liquid is sprayed out of the liquid outlet hole of the plurality of liquid outlet holes 141, the guide groove 142 is also store some water that is not absorbed by the rolling brush 110, thus improving the use reliability of the rolling brush 110.

The liquid spraying component 140 is configured to apply the liquid to the rolling brush 110. In the process of cleaning the floor by the cleaning device 1000, the cleaning liquid used is mainly provided by the liquid spraying component 140 in the cleaning device 1000. The liquid outlet hole of the plurality of liquid outlet holes 141 is arranged opposite to the rolling brush 110 and close to the surface of the rolling brush 110. The plurality of liquid outlet holes 141 are distributed in an axial direction of the rolling brush 110, and the liquid outlet holes 141 are connected to a liquid supply apparatus 210 through a liquid outlet pipeline. Thus, the liquid from the liquid supply apparatus 210 is drained to the surface of the rolling brush 110 through the liquid outlet holes 141. In the implementation, the plurality of liquid outlet holes 141 are equally spaced in the axial direction of the rolling brush 110 to facilitate uniform spray of the liquid to the rolling brush 110. In other implementations, the distance between the plurality of liquid outlet holes 141 is able to be adjusted randomly, and is not limited to equidistant distribution. For example, a middle area of the rolling brush 110 is in contact with more dirt than two end areas, the dirt degree is thus higher, and the distance between the plurality of liquid outlet holes 141 corresponding thereto is able to be greater than the distance between the plurality of liquid outlet holes 141 at the two ends of the rolling brush 110, so that more liquid is sprayed into the middle area of the rolling brush 110, which facilitates cleaning of the rolling brush 110.

As shown in FIG. 7, the inclined planes 1421 of adjacent guide grooves of the plurality of guide grooves 142 are connected with each other, forming a structure with ups and downs. The arc-surface inclined plane 1421 below the liquid outlet hole of the plurality of liquid outlet holes 141 forms a wave shape.

As shown in FIG. 7, in one embodiment implementation, the liquid outlet hole of the plurality of liquid outlet holes 141 is provided with a first liquid dispensing port 1411 and a second liquid dispensing port 1412, and the first liquid dispensing port 1411 and the second liquid dispensing port 1412 face two sides of the liquid outlet hole of the plurality of liquid outlet holes respectively. The first liquid dispensing port 1411 and the second liquid dispensing port 1412 may play the role of shunting, so that the water is able to be sprayed to the rolling brush 110 in all directions and uniformly.

Further, in the implementation, the first liquid dispensing port 1411 and the second liquid dispensing port 1412 both face the inclined planes 1421 at the left and right sides of the liquid outlet hole of the plurality of liquid outlet holes 141 in the guide groove 142, and the water sprayed out of the first liquid dispensing port 1411 and the second liquid dispensing port 1412 flows to the inclined plane 1421 below the liquid outlet hole of the plurality of liquid outlet holes 141 through the inclined planes 1421 at the left and right sides of the liquid outlet hole of the plurality of liquid outlet holes 141, so that the water flows to the rolling brush 110 along the guide groove 142. At this time, since the inclined plane 1421, below the liquid outlet hole of the plurality of liquid outlet holes 141, of the each guide groove of the plurality of guide grooves 142 is the arc surface, and the arc surface is an arc surface with a lower middle part and two higher ends, the liquid flowing from the inclined planes 1421 at the left and right sides of the liquid outlet hole of the plurality of liquid outlet holes 141 to the inclined plane 1421 below the liquid outlet hole of the plurality of liquid outlet holes 141 is evenly dispersed on the inclined plane 1421 below the liquid outlet hole of the plurality of liquid outlet holes 141 instead of vertically flowing to the rolling brush 110 under an action of gravity. As a result, the rolling brush 110 in an opening direction of the liquid outlet hole of the plurality of liquid outlet holes 141 is wet, and the rolling brush 110 in other directions is dry. In order to improve the cleaning efficiency, the liquid spraying component 140 includes a plurality of liquid outlet holes 141, and the orientations of the liquid outlet holes 141 are all the same, so that the liquid is sprayed to the rolling brush 110 through the plurality of liquid outlet holes 141 at the same time, thereby cleaning the rolling brush 110 at the same time and improving the cleaning efficiency of the rolling brush 110. In other embodiments, the liquid outlet hole of the plurality of liquid outlet holes 141 is also directly spray the liquid to the to-be-cleaned surface, which is not limited here.

Specifically, in one embodiment implementation, the apertures of the plurality of liquid outlet holes 141 are different. One mode is that the apertures of the plurality of liquid outlet holes 141 are all different, and the other mode is that the apertures of some liquid outlet holes 141 are the same while the apertures of some liquid outlet holes 141 are different. For example, the middle area of the rolling brush 110 is in contact with more dirt than the two end areas, the dirt degree is thus higher, and the apertures of the liquid outlet holes 141 facing the middle area of the rolling brush 110 among the plurality of liquid outlet holes are small, so that the liquid outlet speed is faster and the impact force is greater under the same liquid outlet amount, and the dirt in the middle area of the rolling brush 110 is easier to clean. The aperture of the liquid outlet hole of the plurality of liquid outlet holes 141 facing the two end areas of the rolling brush 110 is large, so that the dirt in the two end areas of the rolling brush 110 is able to be cleaned by a small impact force. In yet another implementation, the apertures of the plurality of liquid outlet holes 141 in the liquid spraying component 140 are all the same, and the amount and speed of spraying the liquid to each area of the rolling brush 110 are the same, so that the cleaning effect on each area is the same. It is to be noted that the setting mode of the aperture of the liquid outlet hole of the plurality of liquid outlet holes 141 is only exemplary. In the embodiment of the disclosure, the aperture of the liquid outlet hole of the plurality of liquid outlet holes 141 is able to be set according to different cleaning requirements, which is not limited to the setting mode in the above example. The specific setting mode is not specifically limited in the embodiment of the disclosure, as long as the cleaning requirements are met.

In the implementation, as shown in FIG. 6, the liquid spraying component 140 is further provided with a plurality of comb teeth 143, and the plurality of comb teeth 143 are arranged in the axial direction of the rolling brush 110. A serrated end of the comb tooth 143 is vertically arranged. When the rolling brush 110 rotates, the comb tooth 143 combs the rolling brush 110, so that filaments such as hair and silk wound on the rolling brush 110 is able to be scraped off, so as to prevent, as the filaments are wound on the end of the rolling brush 110, the rotation of the rolling brush 110 from being adversely affected. Moreover, compared with being wound on the rolling brush 110, the cleaned hair and other dirt are more easily sucked into the dirt suction channel by the suction port 132, thus improving the cleanliness of the rolling brush 110, avoiding secondary pollution, improving the user experience, and preventing the user from manually touching the rolling brush 110 to remove the hair.

As shown in FIG. 8, in the implementation, the liquid spraying component 140 includes a main water channel 144 and at least two water outlet channels 145 bifurcated on the main water channel 144, and the two water outlet channels 145 include a first water outlet channel 1451 and a second water outlet channel 1452 with the same length, so that the first water outlet channel 1451 and the second water outlet channel 1452 may discharge the water at the same time, and uniform water discharge of the liquid spraying component 140 is ensured.

In other embodiments, more than two water outlet channels 145 are able to be arranged. Herein, one or more first water outlet channels 1451 is able to be arranged, and one or more second water outlet channels 1452 is able to be arranged, which is not limited here, and the specific number is set according to actual needs.

A dispensing port 146 is formed among the main water channel 144, the first water outlet channel 1451 and the second water outlet channel 1452 to communicate with the first water outlet channel 1451 and the second water outlet channel 1452. The first water outlet channel 1451 and the second water outlet channel 1452 are directed in different directions at the dispensing port 146 of the main water channel 144 and extend in a longitudinal direction of the liquid spraying component 140. By such an arrangement, the size of the liquid spraying component 140 in a height direction is reduced.

As shown in FIGS. 3 and 4, the floor brush 100 is provided with a fluid inlet 102, and the liquid spraying component 140 is provided with a liquid inlet hole 147. Both the fluid inlet 102 and the liquid inlet hole 147 are hollow cylinders, and the outer diameter of the liquid inlet hole 147 matches the inner diameter of the fluid inlet 102, so that the liquid inlet hole 147 is able to be inserted into the fluid inlet 102 with a small gap between the two. Further, a sealing ring is arranged on the outer wall of the liquid inlet hole 147 in a sleeving manner to strengthen the tightness of the connection between the fluid inlet 102 and the liquid inlet hole 147 and prevent the liquid from leaking out.

In one embodiment implementation, as shown in FIG. 9, the floor brush 100 further includes a scraper component 150. The scraper component 150 abuts against the rolling brush 110 and the scraper component 150 is arranged on the liquid spraying component 140. The rolling brush 110 may rotate in a preset direction, so as to clean solid and liquid on the floor. The scraper component 150 which cooperates with the rolling brush 110 is able to be used to separate the solid and liquid. Specifically, the rolling brush 110 can clean the solid and liquid on the floor only when in contact with the floor. When the surface of the rolling brush 110 contacts and rubs against the floor, the rolling brush 110 can adhere the solid and liquid to the surface of the rolling brush 110 to rotate with the rolling brush 110. During rotation, the solid and liquid on the surface of the rolling brush 110 may first be separated from the surface of the rolling brush 110 due to own gravity, while the solid and liquid that are not freely separated may rotate with the rolling brush 110, and the surface of the rolling brush 110 with adsorbed solid and liquid may pass through an area where the scraper component 150 is located, so that the solid is scraped off the surface of the rolling brush 110 with the cooperation of the scraper component 150 and the liquid adsorbed inside the rolling brush 110 is squeezed out. The scraper component 150 is located above the suction port 132. The solid or liquid freely separated from the surface of the rolling brush 110 as well as the solid scraped off or liquid squeezed out of the surface of the rolling brush 110 by the scraper component 150 is able to be sucked into the dirt suction channel by the suction port 132 through negative pressure, thus reducing the occurrence of water marks after the cleaning device 1000 is used and shortening the time for the floor to return drying.

In one embodiment, as shown in FIG. 9, the scraper component 150 is a rectangular plate, which is arranged on the floor brush 100 in a stretching manner in the axial direction of the rolling brush 110. The scraper component 150 is as long as the rolling brush 110, and corresponds to the rolling brush 10 in position, so that all-direction abutment against the rolling brush 110 is realized, leaving no dead angle. At this time, the scraper component 150 has a good extrusion effect on the rolling brush 110, and solid waste can be effectively isolated by the scraper component 150, and does not continuously rotate along with the rotation of the rolling brush 110 to cause secondary pollution to the floor. In addition, the scraper component 150 is arranged on the liquid spraying component 140, and the scraper component 150 is located below the plurality of liquid outlet holes 141, so that the scraper component 150 can prevent the liquid sprayed out by the liquid spraying component 140 from flowing downwards, most of the liquid may act on the rolling brush 110, and the liquid blocked by the scraper component 150 is able to be evenly distributed in the axial direction of the rolling brush 110, so as to uniformly wet or clean the rolling brush 110.
