Description

Technical Field

[0001] The utility model relates to the field of household cleaning appliances, and particularly relates to a mopping and washing assembly and a self - moving cleaning robot. Background Art

[0002] With the improvement of living standards, floor - cleaning robots are increasingly entering people's lives because of their simple operation and convenient use. Floor - cleaning robots usually have a mopping function. When mopping, the floor - cleaning robot injects clean water onto the mop to wet the mop, so that the mop can clean the floor. When the floor - cleaning robot works, the cleaned mop will carry sewage, and the sewage may pollute the already - cleaned area. Summary of the Utility Model

[0003] The embodiments of the utility model provide a mopping and washing assembly and a self - moving cleaning robot to solve at least one of the above - mentioned technical problems.

[0004] A mopping and washing assembly according to an embodiment of the utility model, the mopping and washing assembly includes a receiving cavity and a water box. The water box includes a first side wall facing the receiving cavity. A water storage cavity is provided in the water box. A water scraping rib and a water inlet hole are provided on the first side wall. The water inlet hole communicates with the water storage cavity. The water scraping rib extends into the receiving cavity. The water inlet hole is located above the water scraping rib and communicates the receiving cavity and the interior of the water box.

[0005] In the above mopping and washing assembly, a water scraping part is provided on the first side wall of the water box. The water scraping part can scrape the sewage on the cleaning part. The sewage flows into the water storage cavity through the water inlet hole, thereby reducing the sewage on the cleaning part and avoiding the pollution of the already - cleaned area to a certain extent.

[0006] In some embodiments, the water scraping part is inclined on the first side wall from the two side edges of the water box towards the middle bottom.

[0007] In the above mopping and washing assembly, a part of the sewage can accumulate at the middle position of the water scraping part in the water box. When the water box or the self - moving cleaning robot is tilted, the accumulated water at the middle position of the water scraping part is not easy to leak out from the edge of the water box, thereby improving the problem of water leakage when the water box or the self - moving cleaning robot is tilted to a certain extent and enhancing the user experience.

[0008] In some embodiments, the water scraping parts are symmetrically arranged along the central axis of the water box.

[0009] In the above mopping and washing assembly, when the water box is tilted to either the left or the right side, the speed of the accumulated water at the middle of the water scraping part flowing outwards becomes slower, so it is not easy to leak water, and the problem of water leakage when the water box is tilted can be further improved. At the same time, the symmetrical structure of the water scraping part about the central axis is relatively simple in the manufacturing process and can reduce the production cost to a certain extent.

[0010] In some embodiments, the water inlet hole includes a first water inlet hole which penetrates the first side wall along the upper surface of the wiper part.

[0011] In the above-mentioned mopping assembly, since the first water inlet hole penetrates the first side wall along the upper surface of the wiper part, the sewage squeezed out by the wiper part and the cleaning part can flow directly into the first water inlet hole along the upper surface of the wiper part, so that the sewage can be more easily collected and enter the water box, further improving the problem of water leakage.

[0012] In some embodiments, the mopping assembly includes a cleaning assembly and a drip-proof part. The cleaning assembly is rotatably arranged in the accommodating cavity. The drip-proof part extends into the accommodating cavity from the first side wall. The cleaning assembly includes a cleaning part. The cleaning part is in interference fit connection with the wiper part and the drip-proof part. The drip-proof part is located below the wiper part.

[0013] In some embodiments, a connecting part is provided on the first side wall. The connecting part connects the side edge of the drip-proof part, the first side wall and the side edge of the wiper part. Along the width direction of the mopping assembly, the connecting part is inclined from the side edges of the drip-proof part and the wiper part towards the middle.

[0014] In the above-mentioned mopping assembly, the sewage flowing down from the wiper part can drip onto the drip-proof part, and the sewage can be blocked above the drip-proof part and carried away by the cleaning part, preventing the sewage from leaking out from the bottom of the mopping assembly to a certain extent. When the mopping assembly is overturned or tilted, the connecting part can prevent the sewage from leaking to both sides, so that the sewage can be sucked away by the cleaning part, which can further improve the problem of water leakage.

[0015] In some embodiments, the mopping assembly includes a sewage suction pipe and a first bracket. The water box can move relative to the first bracket along the length direction of the mopping assembly. The sewage suction pipe is connected to the first bracket. A first opening is provided at the top of the water storage cavity. The sewage suction pipe extends into the water storage cavity through the first opening. A groove is provided at the bottom of the water storage cavity. The groove extends along the moving direction of the water box. The end of the sewage suction pipe is located in the groove.

[0016] In the above-mentioned mopping assembly, a sliding stroke space for the sewage suction pipe is left on the groove, which can make the sewage flow more easily towards the groove for convergence, facilitating the sewage suction pipe to suck the sewage clean. At the same time, the length of the groove is related to the moving stroke of the water box. The length of the groove ensures that during the movement of the water box, at the starting point or the ending point of the moving stroke, the sewage suction pipe will not contact the side wall of the groove, so the sewage suction pipe will not hinder the movement of the water box.

[0017] In some embodiments, the mopping and washing assembly includes a second bracket and a first bracket. The second bracket is provided with the accommodating cavity. The second bracket is movably connected to the first bracket. The water tank is connected to the second bracket. The second bracket can drive the water tank to move on the first bracket along the length direction of the mopping and washing assembly.

[0018] In some embodiments, a second opening is provided at the bottom of the accommodating cavity. A part of the water tank extends into the accommodating cavity through the second opening. A first limiting component is provided on the surface of the second bracket facing the accommodating cavity. A second limiting component is provided on the water tank. The first limiting component, the second limiting component and the second bracket cooperate together to limit the movement of the water tank in a first direction and a second direction, and the first direction and the second direction are perpendicular to each other.

[0019] In some embodiments, the first limiting component includes a first limiting member and a second limiting member. The first limiting member and the second limiting member are spaced apart on the surface of the second bracket facing the second opening in the second direction. The second limiting component includes a third limiting member and a fourth limiting member.

[0020] The first limiting member and the second bracket jointly limit the movement of the third limiting member in the first direction, thereby limiting the movement of the water tank in the first direction.

[0021] The second limiting member limits the movement of the fourth limiting member in the second direction along the direction close to the second limiting member, thereby limiting the movement of the water tank in the second direction along the direction close to the second limiting member. The second bracket limits the movement of the water tank in the second direction along the direction away from the second limiting member.

[0022] In some embodiments, the first limiting component further includes a limiting hole. The limiting hole is provided on the second bracket. The second limiting component includes a fifth limiting member. The fifth limiting member passes through the limiting hole to limit the movement of the water tank in the first direction.

[0023] In some embodiments, a disassembly button is provided on the water tank. The disassembly button is connected to the fourth limiting member. The disassembly button is configured to drive the fourth limiting member to disengage from the second limiting member when being pressed, so that the water tank can move in the second direction along the direction away from the second limiting member.

[0024] In the above-mentioned mopping and washing assembly, the second bracket and the first limiting member cooperate together to limit the movement of the water box in the up-and-down direction (the first direction), and the second bracket and the second limiting member cooperate together to limit the movement of the water box in the front-and-back direction (the second direction). This can further improve the stability of the water box installation and is also beneficial to simplifying the installation and disassembly of the water box.

[0025] In some embodiments, the mopping and washing assembly includes a first driving assembly, which is installed on the first bracket, and the first driving assembly is configured to drive the second bracket and the water box to move on the first bracket along the length direction of the mopping and washing assembly.

[0026] In the above-mentioned mopping and washing assembly, the second bracket and the water box can be telescoped along with the movement of the cleaning assembly. During the working process of the cleaning assembly, it can cooperate with the cleaning assembly to clean the corners of the ground, and the sewage suction pipe can also cooperate with the movement of the water box to further drain the sewage in the water box.

[0027] In some embodiments, the mopping and washing assembly includes a water distribution plate and a cleaning assembly. At least a part of the cleaning assembly is located in the accommodating cavity. The water scraping part is connected to the cleaning assembly in an interference fit manner. The water distribution plate is arranged on the surface of the second bracket facing the accommodating cavity, and the water distribution plate is provided with a plurality of water outlet holes. The water distribution plate is configured to supply water to the cleaning assembly through the plurality of water outlet holes to moisten the cleaning assembly.

[0028] In the above-mentioned mopping and washing assembly, through the water distribution plate, the clean water is evenly distributed to the cleaning parts, and the wetting effect of the cleaning parts remains consistent to a certain extent. Therefore, the wetting effect of the ground remains consistent to a certain extent during the process of cleaning the ground, thus ensuring the cleaning effect.

[0029] In some embodiments, the plurality of water outlet holes are evenly arranged along the length direction of the mopping and washing assembly.

[0030] In the above-mentioned mopping and washing assembly, when the water box is self-cleaning, the clean water can be more evenly distributed to the cleaning parts. In some embodiments, the mopping and washing assembly includes a water leveling strip and a second bracket. The second bracket is provided with the accommodating cavity. The water leveling strip protrudes on the surface of the second bracket facing the accommodating cavity. The cleaning assembly includes a cleaning part. The water leveling strip is connected to the cleaning part in an interference fit manner. In the rotation direction of the cleaning part, the water leveling strip is located behind the water distribution plate.

[0031] In the above-mentioned mopping and washing assembly, the water leveling strip is connected to the cleaning assembly in an interference fit manner, which can effectively improve the effect of quickly and evenly wetting the cleaning parts and save the time of self-cleaning.

[0032] In some embodiments, the mopping and washing assembly further includes a second driving assembly. The cleaning assembly includes a rotating shaft and a cleaning member. The cleaning member is sleeved outside the rotating shaft. The second driving assembly is connected to the rotating shaft and configured to drive the rotating shaft to rotate so as to drive the cleaning member to rotate.

[0033] In the above mopping and washing assembly, the second driving assembly can drive the rotating shaft to rotate so as to drive the cleaning member to rotate, enabling the cleaning member to evenly cover and clean the ground.

[0034] A self - moving cleaning robot of the present utility model includes the mopping and washing assembly of any of the above - mentioned embodiments.

[0035] In the above self - moving cleaning robot, a water scraping portion is provided on the first side wall of the water tank. The water scraping portion can scrape off the sewage on the cleaning member, and the sewage flows into the water storage cavity through the water inlet hole, thereby reducing the sewage on the cleaning member and avoiding sewage pollution of the already cleaned area to a certain extent.

[0055] Please refer to Figures 1 to 4 , a mopping and washing assembly 100 provided by an embodiment of the present utility model includes a receiving cavity 10 and a water box 12. The water box 12 includes a first side wall 14 facing the receiving cavity 10. A water storage cavity 30 is provided in the water box 12. A water scraping portion 16 and a water inlet hole 17 are provided on the first side wall 14. The water inlet hole 17 communicates with the water storage cavity 30. The water scraping portion 16 extends into the receiving cavity 10. The water inlet hole is located above the water scraping portion 16 and communicates with the inside of the receiving cavity 10 and the water box 12.

[0056] In the above mopping and washing assembly 100, a water scraping portion 16 is provided on the first side wall 14 of the water box 12. The water scraping portion 16 can scrape the sewage on the cleaning member 74. The sewage flows into the water storage cavity 30 through the water inlet hole 17, thereby reducing the sewage on the cleaning member 74 and avoiding the pollution of the already cleaned area by sewage to a certain extent.

[0057] Specifically, the self - moving cleaning robot 200 includes, but is not limited to, a floor sweeper, a floor washer, a vacuum cleaner, a pressure washer, etc. The self - moving cleaning robot 200 includes a body 80 and a mopping component 100. Optionally, please refer to Figure 1 , the mopping component 100 may include a cleaning component 20. The cleaning component 20 includes a cleaning piece 74 and a rotating shaft 72. The mopping component 100 is installed at the rear of the body 80 and has a mopping function. When mopping the floor, the self - moving cleaning robot 200 injects clean water onto the cleaning piece 74 of the cleaning component 20 to moisten the cleaning piece 74, so that the cleaning piece 74 can clean the floor. The cleaning piece 74 includes, but is not limited to, a mop cloth and a wiping cloth.

[0058] The mopping component 100 is an important part of the self - moving cleaning robot 200 and is one of the main components for cleaning the floor. The working process of the mopping component 100 is roughly as follows: Inject clean water onto the cleaning piece 74. The cleaning piece 74 is sleeved outside the rotating shaft 72. Driven by the rotating shaft 72, the cleaning piece 74 rotates and can clean the floor. The water scraping part 16 extends into the accommodating cavity 10, and the water scraping part 16 that presses against the cleaning 74 scrapes the sewage carried on the cleaning piece 74 into the water box 12, and then the sewage suction pipe 26 drains the sewage in the water box 12. Among them, the water box 12 is used to collect the sewage on the cleaning piece 74. When the self - moving cleaning robot 200 works, the mopped cloth after cleaning will carry sewage, and the sewage may pollute the already cleaned area.

[0059] The water scraping part 16 is one of the important components of the mopping component 100. The water scraping part 16 can squeeze out the sewage carried on the cleaning piece 74, and then the sewage flows into the water box 12 through the water inlet hole 17. In the embodiment of the present utility model, please refer to Figure 5 , the shape of the end of the water scraping part 16 is serrated to scrape off more sewage. It can be understood that in other embodiments, the shape of the end of the water scraping part 16 is not limited to serrated, and can also be linear or other shapes.

[0060] The present utility model does not specifically limit the material of the water scraping part 16. In one example, the material of the water scraping part 16 can be silicone, rubber, polyurethane, plastic and other materials. Optionally, the water scraping part 16 and the water box 12 are connected as an integral structure.

[0061] Optionally, the water inlet hole 17 can be arranged along the length direction of the mopping component 100. The length of the area where the water inlet hole 17 is arranged is basically the same as the length of the water scraping part 16 along the length direction of the mopping component 100, so that the sewage scraped by the water scraping part 16 can be discharged into the water box 12 in time. Optionally, the length direction of the mopping component 100 is along Figure 6 and Figure 7 the left - right direction shown, and the width direction is along Figure 6and Figure 7 the front - rear direction shown. Optionally, the wiper part 16 can be strip - shaped, and the length of the wiper part 16 along the length direction of the mopping and washing assembly 100 is equivalent to the length of the cleaning part 74 along the length direction of the mopping and washing assembly 100.

[0062] In some embodiments, the wiper part 16 is inclined on the first side wall 14 from the two - side edges of the water tank 12 towards the middle bottom (as Figure 2 shown).

[0063] In this way, a part of the sewage can accumulate at the middle position of the wiper part 16 within the water tank 12. When the water tank 12 is inclined, the accumulated water at the middle position of the wiper part 16 is not easily leaked from the edge of the water tank 12, thereby improving the problem of water leakage when the water tank 12 is inclined to a certain extent.

[0064] Specifically, please refer to Figure 2 , the wiper part 16 is arranged on the first side wall 14, and the wiper part 16 is inclined from the two - side edges of the water tank 12 towards the middle bottom, and the inclination angle with the central axis L is A. The size of the inclination angle A can be specifically defined according to actual needs, and the present utility model does not make specific limitations thereon.

[0065] Along the length direction of the mopping and washing assembly 100, the wiper part 16 is inclined from the two - side edges of the water tank 12 towards the middle bottom. When the wiper part 16 scrapes off the sewage, on the one hand, most of the sewage will flow into the water tank 12 through the water inlet hole 17, and a small part of the sewage will flow along the wiper part 16 towards the middle of the water tank 12, and the accumulated sewage will flow into the water tank 12 through the water inlet hole 17 in the middle of the water tank 12. Even if there is residual sewage that does not flow into the water tank 12, this residual sewage will accumulate at the position of the wiper part 16 close to the middle of the water tank 12. When the mopping and washing assembly 100 or the water tank 12 is inclined, the sewage (hereinafter referred to as accumulated water) at the position of the wiper part 16 close to the middle of the water tank 12 needs to flow through a longer path to reach the edge of the water tank 12. During the flowing process, the accumulated water will adhere to the wiper part 16 on the flowing path and will be discharged into the water tank 12 through the water inlet hole 17 on the flowing path, thereby continuously reducing the amount of accumulated water. It is possible that the accumulated water disappears before reaching the edge of the water tank 12. Even if the accumulated water can flow to the edge of the water tank 12, the amount of accumulated water is also relatively small. Moreover, the sewage accumulated at the position of the wiper part 16 close to the middle of the water tank 12 can also be sucked away by the cleaning part 74.

[0066] The sewage at the position of the wiper part 16 close to the middle of the water tank 12 needs a longer time to flow out of the edge of the water tank 12 due to the longer flowing path, which allows the situation that the mopping and washing assembly 100 or the water tank 12 is inclined for a short time without the accumulated water leaking. To sum up, the problem of water leakage when the water tank 12 is inclined can be improved to a certain extent, enhancing the user experience.

[0067] In some embodiments, refer to Figure 2 , the wiper part 16 is symmetrically arranged along the central axis L of the water box 12.

[0068] In this way, when the water box 12 tilts to either the left or right side, the speed of the accumulated water in the middle of the water box 12 flowing outwards on the wiper part 16 becomes slower, so it is not easy to leak water, and the problem of water leakage when the water box 12 tilts can be further improved. At the same time, the symmetrical structure of the wiper part 16 with respect to the central axis L is relatively simple in the manufacturing process, and the production cost can be reduced to a certain extent.

[0069] In Figure 2 , the central axis L of the water box 12 is the central axis L of the water box 12 along the length direction of the mopping and washing assembly 100.

[0070] In some embodiments, refer to Figure 1 , the water inlet hole 17 includes a first water inlet hole 18, and the first water inlet hole 18 penetrates the first side wall 14 along the upper surface of the wiper part 16.

[0071] In this way, since the first water inlet hole 18 penetrates the first side wall 14 along the upper surface of the wiper part 16, the sewage squeezed out by the wiper part 16 and the cleaning part 74 can flow directly into the first water inlet hole 18 along the upper surface of the wiper part 16, so that the sewage can be more easily collected into the water box 12, further improving the problem of water leakage.

[0072] Specifically, please combine Figure 2 , in the embodiment of the present utility model, the water inlet hole 17 may include a second water inlet 19, the second water inlet hole 19 is located above the first water inlet hole 18, and the shape of the first side wall 14 is adapted to the shape of the cleaning part 74. In Figure 1 , the cleaning assembly 20 is a crawler type cleaning assembly 20, the part of the cleaning part 74 in contact with the first side wall 14 is arc-shaped, and the first side wall 14 is arc-shaped adapted to the part in contact with the cleaning part 74, so that the fitting degree between the two is relatively high, and the resistance when the cleaning part 74 rotates can be reduced. It can be understood that in other embodiments, the cleaning assembly 20 may also be a turntable type cleaning assembly 20 or a drum type cleaning assembly 20.

[0073] The setting of the second water inlet hole 19 can enable the sewage on the wiper part 16 to flow into the water box through the second water inlet hole 19 when the amount of sewage on the wiper part 16 is relatively large, further reducing or avoiding the occurrence of sewage leakage.

[0074] Optionally, please combine Figure 2, the number of the first water inlet holes 18 and the second water inlet holes 19 is multiple. A plurality of the first water inlet holes 18 and a plurality of the second water inlet holes 19 can form a mesh hole 76. When the sewage extruded by the wiper part 16 and the cleaning part 74 flows through the mesh hole 74, the mesh hole 74 can filter some larger fixed stains, avoiding the situation that the fixed stains flow into the water box 12 and cause the sewage suction pipe 26 to be blocked.

[0075] In some embodiments, please refer to Figure 1 , the mopping and washing assembly 100 includes a cleaning assembly 20 and a drip prevention part 22. The cleaning assembly 20 is disposed in the accommodating cavity 10, and the drip prevention part 22 extends into the accommodating cavity 10 from the first side wall 14. The cleaning assembly 20 includes a cleaning part 74, and the cleaning part 74 is connected with the wiper part 16 and the drip prevention part 22 in an interference fit manner. The drip prevention part 22 is located below the wiper part 16.

[0076] In this way, it can prevent sewage from leaking out from the bottom of the mopping and washing assembly 100 to a certain extent.

[0077] Specifically, when the wiper part 16 scrapes sewage from the cleaning part 74, some sewage may flow along the edge of the wiper part 16 to the lower part of the wiper part 16 and leak out from the bottom of the mopping and washing assembly 100. By providing the drip prevention part 22 and, in the rotation direction of the cleaning assembly 20, the drip prevention part 22 is located below the wiper part 16, so that the sewage flowing down from the wiper part 16 can drip onto the drip prevention part 22, and the sewage can be blocked above the drip prevention part 22 and carried away by the cleaning part 74 for suction. Optionally, the drip prevention part 22 can be strip-shaped.

[0078] In Figure 1 , the rotation direction of the cleaning part 74 during normal cleaning work is the clockwise direction. In the clockwise direction, the drip prevention part 22 is located behind the wiper part 16, so that after the wiper part 16 wipes water, the drip prevention part 22 can block the sewage on the drip prevention part 22.

[0079] Optionally, the drip prevention part 22 can be along the length direction of the mopping and washing assembly 100, and the length of the drip prevention part 22 is substantially the same as the length of the wiper part 16 along the length direction of the mopping and washing assembly 100, so that the sewage scraped off by the wiper part 16 can be timely blocked above the drip prevention part 22. The length direction of the mopping and washing assembly 100 is along the Figure 6 and Figure 7 shown left - right direction, and the width direction is along the Figure 6 and Figure 7 shown front - back direction.

[0080] Along the length direction of the mopping component 100, the drip-proof part 22 is inclined from the two side edges of the water tank 12 towards the middle bottom. When the sewage scraped by the wiper part 16 flows to the drip-proof part 22, the sewage can be blocked above the drip-proof part 22, making it easier for the cleaning part 74 to carry and suck away the sewage. Optionally, the drip-proof parts 22 are symmetrically arranged along the central axis L of the water tank 12. In this way, when the water tank 12 tilts to either the left or right side, the accumulated water in the middle of the water tank 12 is difficult to leak out from the bottom of the mopping component 100, so it is not easy to leak water, and the problem of water leakage when the water tank 12 tilts can be further improved.

[0081] The present utility model does not limit the material of the drip-proof part 22. In one example, the material of the drip-proof part 22 can be materials such as plastic, rubber or polyurethane. Optionally, the drip-proof part 22, the wiper part 16 and the water tank 12 can be connected into an integral structure.

[0082] In some embodiments, please refer to Figure 1 and Figure 2 , a connecting part 24 is provided on the first side wall 14. The connecting part 24 connects the side edge of the drip-proof part 22, the first side wall 14 and the side edge of the wiper part 16. Along the width direction of the mopping component 100, the connecting part 24 is inclined from the side edges of the drip-proof part 22 and the wiper part 16 towards the middle. In Figure 6 and Figure 7 , the width direction of the mopping component 100 is along the front-rear direction.

[0083] In this way, when the mopping component 100 is overturned or tilted, the connecting part 24 can prevent the sewage from leaking to both sides, so that the sewage can be sucked away by the cleaning part 74.

[0084] Specifically, please refer to Figure 2 , in one embodiment, two connecting parts 24 are provided on the first side wall 14. The two connecting parts 24 can be respectively arranged on the two side edges of the drip-proof part 22 and the wiper part 16 along the length direction of the mopping component 100. In Figure 2 , the two connecting parts 24 are respectively a left connecting part 24 and a right connecting part 24. The left connecting part 24 connects the left side edge of the drip-proof part 22 and the left side edge of the wiper part 16, and the right connecting part 24 connects the right side edge of the drip-proof part 22 and the right side edge of the wiper part 16.

[0085] Along the width direction of the mopping and washing assembly 100, the left connecting portion 24 slopes rightward from front to back, and the right connecting portion 24 slopes leftward from front to back, so that the left connecting portion 24 and the right connecting portion 24 function as a guiding structure from outside to inside, blocking the sewage on the water-dripping prevention portion 22 and the water scraping portion 16 on the water-dripping prevention portion 22 and the water scraping portion 16. When the mopping and washing assembly 100 is overturned or tilted, the connecting portion 24 can prevent the sewage from leaking out to both sides, so that the sewage can be sucked away by the cleaning member 74. In other embodiments, the connecting portion 24 may also be provided on any one side edge, and the connecting portion 24 can prevent the sewage from leaking out to the side where the connecting portion 24 is located. The setting position of the connecting portion 24 is specifically defined according to actual needs, and the present invention does not make specific limitations on this.

[0086] The present invention embodiment does not make specific limitations on the type of the connecting portion 24. Optionally, the connecting portion 24 may be a sealing strip made of rubber or silica gel material. The sealing strip is respectively connected to the water scraping portion 16 and the water-dripping prevention portion 22, and can effectively prevent the sewage from leaking out from both sides to a certain extent. In other embodiments, the connecting portion 24 may also be a water blocking piece made of plastic material.

[0087] In some embodiments, please refer to Figure 1 , the mopping and washing assembly 100 includes a sewage suction pipe 26 and a first bracket 28. The water box 12 can move relative to the first bracket 28 along the length direction of the mopping and washing assembly 100. The sewage suction pipe 26 is connected to the first bracket 28. A first opening 32 is provided at the top of the water storage cavity 30. The sewage suction pipe 26 extends into the water storage cavity 30 through the first opening 32. A groove 34 is provided at the bottom of the water storage cavity 30. The groove 34 extends along the moving direction of the water box 12. The end of the sewage suction pipe 26 is located in the groove 34.

[0088] In this way, a sliding stroke space for the sewage suction pipe 26 is left on the groove 34, which can make the sewage flow to the groove 34 more easily for convergence, facilitating the sewage suction pipe 26 to suck the sewage clean. At the same time, the length of the groove 34 is related to the moving stroke of the water box 12. The length of the groove 34 ensures that during the movement of the water box 12, at the start or end of the moving stroke, the sewage suction pipe 26 will not abut against the side wall of the groove 34, so the sewage suction pipe 26 will not hinder the movement of the water box 12.

[0089] Specifically, in the embodiments of the present utility model, the two side edges of the groove 34 are inclined towards the middle, which can make the sewage more easily concentrated at the bottom of the groove 34, so that the sewage suction pipe 26 can more conveniently suck out the sewage. The present utility model does not limit the angle at which the two side edges of the groove 34 are inclined towards the middle. When the self-moving cleaning robot 200 performs cleaning at the corners of the whole house, the cleaning component 20 needs to extend out of the body 80 for corner cleaning. The telescopic movement of the cleaning component 20 allows the cleaning component 20 to move between the body of the cleaning device 200 and the ground corners, which can make the cleaning range wider and improve the efficiency and quality of corner cleaning to a certain extent. During the cleaning process, the sewage suction pipe 26 is fixedly connected to the first bracket 28, and the water box 12 moves telescopically together with the cleaning component 20. However, it is difficult for the water box 12 to extend out of the body 80 according to different cleaning distances, and at the same time, the sewage suction pipe 26 can always suck out the sewage collected in the water storage cavity 30 of the water box 12 cleanly.

[0090] In Figure 6 and Figure 7 when the cleaning device 200 performs corner cleaning, the moving direction of the water box 12 is the left-right direction. When the cleaning device 200 performs corner cleaning, the water box 12 extends out of the body 80 with the cleaning component 20 and moves in the left-right direction. The sewage suction pipe 26 is fixedly connected to the first bracket 28 and does not move with the water box 12 during operation. The end of the sewage suction pipe 26 is located in the groove 34, and there is a sliding stroke space for the sewage suction pipe 26 on the groove 34. When the water box 12 moves, the end of the sewage suction pipe 26 moves relative to the water box 12 in the groove 34, and the end of the sewage suction pipe 26 always stays in the groove 34. The length of the groove 34 is related to the moving stroke of the water box 12, so that during the movement of the water box 12, at the starting point or the end point of the moving stroke, the sewage suction pipe 26 will not contact the side wall of the groove 34. Therefore, the water box 12 can avoid the sewage suction pipe 26 through the groove 34, so that the movement of the water box 12 and the sewage suction work of the sewage suction pipe 26 are not hindered. In some embodiments, please refer to Figure 1 and the mopping component 100 includes a first bracket 28 and a second bracket 36. The second bracket 36 is provided with a receiving cavity 10. The second bracket 36 is movably connected to the first bracket 28. The water box 12 is connected to the second bracket 36, and the second bracket 36 can drive the water box 12 to move on the first bracket 28 along the length direction of the mopping component 100.

[0091] In this way, the cleaning range of the mopping component 100 can be increased.

[0092] Specifically, in one embodiment, the mopping component 100 includes a cleaning component 20. The cleaning component 20 is fixed to the second bracket 36 and partially located in the receiving cavity 10. The second bracket 36 can drive the water box 12 and the cleaning component 20 to move on the first bracket 28 along the length direction of the mopping component 100.

[0093] When the self - moving cleaning robot 200 performs corner cleaning of the whole house, the cleaning component 20 needs to extend out of the body 80 to clean the corners. Thus, the second bracket 36 can drive the water tank 12 and the cleaning component 20 to move on the first bracket 28 along the length direction of the mopping component 100 so as to extend out of the body 80 (as Figure 7 shown), to increase the cleaning range and achieve the purpose of including but not limited to corner cleaning.

[0094] Optionally, the water tank 12 is detachably connected to the second bracket 36 to facilitate the user to detach the water tank 12 to clean the sewage and install the water tank 12 on the second bracket 36. The detachable connection methods include but are not limited to snap - fasteners, bolts and the like.

[0095] Please refer to Figure 4 , a second opening 38 is provided at the bottom of the accommodating cavity 10. A part of the water tank 12 extends into the accommodating cavity 10 through the second opening 38. A first limiting component 40 is provided on the surface of the second bracket 36 facing the accommodating cavity 10, and a second limiting component 42 is provided on the outer side of the water tank 12. The first limiting component 40, the second limiting component 42 and the second bracket 36 cooperate together to limit the movement of the water tank 12 in the first direction and the second direction, and the first direction is perpendicular to the second direction.

[0096] Thus, the water tank 12 can be limited, so that the water tank 12 can be more stably installed on the second bracket 36.

[0097] In Figure 4 , the first direction is the up - and - down direction, and the second direction is the front - and - back direction, and the first direction is perpendicular to the second direction. That is to say, the first limiting component 40, the second limiting component 42 and the second bracket 36 can cooperate together to limit the movement of the water tank 12 in the front - and - back and up - and - down directions, so that the water tank 12 can be more stably installed on the second bracket 36.

[0098] In some embodiments, please refer to Figure 3 and Figure 4 , the first limiting component 40 includes a first limiting member 44 and a second limiting member 46. The first limiting member 44 and the second limiting member 46 are spaced apart on the surface of the second bracket 36 facing the second opening 38 in the second direction. The second limiting component includes a third limiting member 48 and a fourth limiting member 50;

[0099] The first limiting member 44 and the second bracket 36 jointly limit the movement of the third limiting member 48 in the first direction, thereby limiting the movement of the water tank 12 in the first direction;

[0100] The second limiting member 46 restricts the movement of the fourth limiting member 50 in the second direction towards the second limiting member 46, thereby restricting the movement of the water box 12 in the second direction away from the second limiting member 46.

[0101] Please refer to Figure 4 , the surface of the second bracket 36 facing the second opening 38 in the second direction is the inner surface of the second bracket 36 facing the second opening 38. The first limiting member 44 and the second limiting member 46 are spaced apart and arranged on the inner surface of the second bracket 36 facing the second opening 38. Optionally, the water box 12 is provided with a water storage cavity 30. The third limiting member 48 is arranged on the surface of the first side wall 14 facing the water storage cavity 30, and the fourth limiting member 50 is arranged on the surface of the second side wall of the water box 12 facing the water storage cavity 30. The second side wall is arranged opposite to the first side wall 14.

[0102] In Figure 4 , the second direction is the front-back direction. In the second direction, the direction towards the second limiting member 46 is from the back to the front, and the direction away from the second limiting member 46 in the second direction is from the front to the back. That is, the second limiting member 46 restricts the movement of the fourth limiting member 50 from the back to the front, thereby restricting the movement of the water box 12 from the back to the front, and the second bracket 36 restricts the movement of the water box 12 from the front to the back.

[0103] Specifically, the second bracket 36 includes a top plate 82 and a rear side plate 84. The top plate 82 is connected to the rear side plate 84. The first limiting member 44 and the second limiting member 46 are arranged on the surface of the top plate 82 facing the accommodating cavity 10. The rear side plate can abut against the rear side wall (the second side wall) of the water box 12 at the rear of the water box 12, so that the second bracket 36 restricts the movement of the water box 12 from the front to the back. The second limiting member 46 is located on the front side of the fourth limiting member 50, so as to restrict the movement of the fourth limiting member 50 from the back to the front, thereby restricting the movement of the water box 12 from the back to the front.

[0104] Optionally, the second bracket 36 further includes a left side plate and a right side plate. The left side plate and the right side plate can both be provided with side holes. The left and right sides of the water box are both provided with bumps, and the bumps pass through the side holes, so as to limit the water box in the up-down direction (the first direction) and the left-right direction (the third direction) on both sides.

[0105] In summary, the second bracket 36 and the second limiting member 46 cooperate together to restrict the movement of the water box 12 in the front-back direction (the second direction).

[0106] When the top plate 82 cooperates with the first limiting member 44, it can restrict the movement of the third limiting member 48 in the up-down direction, thereby restricting the movement of the water box 12 in the up-down direction.

[0107] In summary, the second bracket 36 and the first limiting member 44 cooperate together to limit the movement of the water box 12 in the up and down direction (the first direction).

[0108] Please refer to Figure 3 and Figure 4 , the first limiting assembly 40 includes a limiting hole 52, the limiting hole 52 is provided on the second bracket 36, the second limiting assembly 42 includes a fifth limiting member 54, and the fifth limiting member 54 passes through the limiting hole 52 to limit the movement of the water box 12 along the first direction.

[0109] In this way, the stability of the installation of the water box 12 can be further improved.

[0110] Specifically, please refer to Figure 6 , the limiting hole 52 is provided on the rear side plate 84 of the second bracket 36. The fifth limiting member 54 is provided on the outer side of the second side wall. The fifth limiting member 54 passes through the limiting hole 52, and the edge of the limiting hole 52 in the first direction can abut against the edge of the fifth limiting member 54 in the first direction, so that the second bracket 36 can limit the movement of the water box 12 along the first direction (such as the up and down movement).

[0111] The present utility model does not specifically limit the number of the fifth limiting member 54 and the limiting hole 52. In Figure 6 , the number of both the limiting hole 52 and the fifth limiting member 54 is two, and one fifth limiting member 54 passes through a corresponding one limiting hole 52.

[0112] In some embodiments, please refer to Figure 3 and Figure 4 , the water box 12 is provided with a disassembly button 56, the disassembly button 56 is connected to the second limiting assembly 42, and the disassembly button 56 is configured to drive the second limiting assembly 42 to disengage from the first limiting assembly 40 when being pressed, so that the water box 12 can move away in the second direction.

[0113] In this way, the disassembly of the water box 12 can be facilitated.

[0114] Specifically, the limiting member mainly restricts or controls the position, direction and stroke of the water box 12 through specific mechanisms and devices, prevents excessive movement, collision or damage of the water box 12, and ensures the stability and accuracy of the operation of the mopping assembly 100. The stroke of the movement of the water box 12 is related to the position and distance of the limiting member. The position and distance of the limiting member can be specifically defined according to actual needs, and the present utility model does not make specific limitations thereon.

[0115] Refer to Figure 1 , Figure 4 and Figure 8 , the first direction is the up and down direction, and the second direction is the front and back direction. The installation process of the water box 12 is as follows: when the water box 12 has not been installed into the second bracket 36, the water box 12 can be inFigure 4 Move the position shown forward by a certain distance so that in the front - rear direction, the fourth limiting member 50 is located between the first limiting member 44 and the second limiting member 46, and the third limiting member 48 is separated from the first limiting member 44 and is located in front of the first limiting member 44. At this time, push the water box 12 from the bottom of the second bracket 36 upwards, so that the top of the water box 12 abuts against the lower surface of the second bracket 36. Then push the water box 12 from front to back, so that the third limiting member 48 contacts the first limiting member 44. The first limiting member 44 and the second bracket 36 limit the movement of the third limiting member 48 in the up - down direction (the first direction), thereby limiting the movement of the water box 12 in the up - down direction (the first direction); the fourth limiting member 50 can cross over the second limiting member 46 and be located behind the second limiting member 46, and abut against the second limiting member 46 at the rear side of the second limiting member 46. The second limiting member 46 limits the forward movement of the fourth limiting member 50, thereby limiting the forward movement of the water box 12; the fifth limiting member 54 passes through the limiting hole 52, and the first limiting component 40 limits the movement of the water box 12 in the first direction. Therefore, the water box 12 is connected to the second bracket. Thus, the water box 12 can be installed in the second bracket 36.

[0116] The disassembly process of the water box 12 is as follows: First, press the disassembly button 56 and push it from back to front, which can drive the water box 12 to move from back to front, and cause the fourth limiting member 50 connected to the disassembly button 56 to deform and cross over the second limiting member 46. Then, the fourth limiting member 50 is located in front of the second limiting member 46, thereby removing the restriction of the second limiting member 46 on the fourth limiting member 50. The movement of the water box 12 from back to front also causes the third limiting member 48 to be released from the restriction of the first limiting member 44, and the fifth limiting member 54 to be released from the restriction of the limiting hole 52. Therefore, the whole water box 12 will be detached from the second bracket 36, and then the water box 12 can be taken out from the bottom of the second bracket 36.

[0117] In some embodiments, please refer to Figure 6 and Figure 7 , the mopping and washing assembly 100 further includes a first driving assembly 58. The first driving assembly 58 is installed on the first bracket 28, and the first driving assembly 58 is configured to drive the second bracket 36 and the water box 12 to move on the first bracket 28 along the length direction of the mopping and washing assembly 100.

[0118] In this way, the second bracket 36 and the water box 12 can be telescoped along with the movement of the cleaning assembly 20. During the working process of the cleaning assembly 20, it can cooperate with the cleaning assembly 20 to clean the corners of the ground, and the sewage suction pipe 26 can also cooperate with the movement of the water box 12 to further drain the sewage in the water box 12.

[0119] Specifically, in the embodiment of the present utility model, the first driving assembly 58 adopts a driving mode of an electric motor. It can be understood that in other embodiments, the first driving assembly 58 can also adopt a hydraulic driving mode or a cylinder driving mode.

[0120] Please refer to Figure 6 and Figure 7 , the length direction of the mopping and scrubbing assembly 100 is the left - right direction. The first driving assembly 58 includes a first motor 60 and a transmission member 62. The first motor 60 is a rotary motor, and the transmission member 62 includes a screw rod. After the first motor 60 is powered on, it performs a rotary motion, and the rotational force is transmitted to the nut fixed on the second bracket 36 through the screw rod. The nut moves along the axial direction of the screw rod, driving the second bracket 36 and the water box 12 to move on the first bracket 28 along the length direction of the mopping and scrubbing assembly 100, so that the mopping and scrubbing assembly 100 can perform a telescopic motion. In other embodiments, the first motor 60 can adopt a linear motor. The type of the first motor 60 of the first driving assembly 58 can be specifically defined according to actual needs, and the present utility model does not make specific limitations on this.

[0121] In some embodiments, please refer to Figure 1 and Figure 5 , the mopping and scrubbing assembly 100 includes a water - distributing plate 66 and a cleaning assembly 20. At least a part of the cleaning assembly 20 is located in the accommodating cavity 10. The water - scraping part 16 is connected to the cleaning assembly 20 in an interference - fit manner. The water - distributing plate 66 is provided with a plurality of water outlet holes 68, and the water - distributing plate 66 is configured to supply water to the cleaning assembly 20 through the plurality of water outlet holes 68 to moisten the cleaning assembly 20.

[0122] In this way, through the water - distributing plate 66, the clean water is evenly distributed to the cleaning member 74, and the wetting effect of the cleaning member 74 is kept consistent to a certain extent. Therefore, during the process of cleaning the ground, the wetting effect of the ground is kept consistent to a certain extent, thus ensuring the cleaning effect.

[0123] The present utility model does not make specific limitations on the material of the water - distributing plate 66. In one example, the material of the water - distributing plate 66 can be stainless steel, aluminum alloy, high - density polyethylene or the like.

[0124] Specifically, the water - distributing plate 66 is arranged on the surface of the second bracket 36 facing the accommodating cavity 10. The interference - fit connection between the water - scraping part 16 and the cleaning assembly 20 means that the water - scraping part 16 and the cleaning member 74 can be mutually extruded, which is convenient for the water - scraping part 16 to scrape off the sewage carried on the cleaning member 74. Optionally, in one embodiment, the extrusion amount between the water - scraping part 16 and the cleaning member 74 is less than the thickness of the cleaning member 74, so that the rotational resistance of the cleaning assembly 20 is small.

[0125] In the embodiment of the present utility model, please refer to Figure 1, the water diversion plate 66 is disposed in a recessed area on the surface of the second bracket 36 facing the accommodation cavity 10, and the shape profile of the recessed area closely fits the shape profile of the water diversion plate 66. The recessed area provides a stable support for the water diversion plate 66, ensuring the stability of the placement of the water diversion plate 66 to a certain extent and avoiding unnecessary shaking or movement. At the same time, it also achieves a concealed effect for the water diversion plate 66, making the water diversion plate 66 almost invisible and saving placement space.

[0126] In some embodiments, refer to Figure 5 , a plurality of water outlet holes 68 are uniformly arranged along the length direction of the mopping assembly 20.

[0127] In this way, the clean water can be more evenly distributed to the cleaning member 74.

[0128] Specifically, please combine Figure 5 , the length direction of the mopping assembly 100 is the left-right direction. In the embodiment of the present invention, the uniform arrangement of a plurality of water outlet holes 68 along the length direction of the mopping assembly 100 may mean that they are arranged in a row along the length direction of the water diversion plate 66, and the distance between adjacent two water outlet holes 68 is equal. In other embodiments, a plurality of water outlet holes 68 are distributed in a matrix or other ways on the water diversion plate 66, and the present invention does not make specific limitations thereto.

[0129] In the embodiment of the present invention, the water outlet holes 68 are circular through holes. In other embodiments, the water outlet holes 68 may be square through holes or triangular through holes, etc. The shape of the water outlet holes 68 can be specifically defined according to actual needs, and the present invention does not make specific limitations thereto.

[0130] In some embodiments, refer to Figure 1 , the mopping assembly 100 further includes a water equalizing bar 70 and a second bracket 36. The second bracket 36 is provided with an accommodation cavity 10. The water equalizing bar 70 protrudes on the surface of the second bracket 36 facing the accommodation cavity 10. The cleaning assembly 20 includes a cleaning member 74. The water equalizing bar 70 is connected to the cleaning member 74 by interference fit. In the rotation direction of the cleaning member 74, the water equalizing bar 70 is located behind the water diversion plate 66.

[0131] When the mopping assembly 100 performs self-cleaning, it is necessary to inject clean water onto the cleaning member 74 through the water diversion plate 66 so that the cleaning member 74 can be evenly wetted. During the self-cleaning process of the mopping assembly 100, it is difficult for the water poured down by the water diversion plate 66 to quickly and evenly wet the cleaning member 74.

[0132] Therefore, a water equalizing strip 70 is provided behind the water distribution plate 66 in the clockwise rotation direction of the cleaning member 74. During the self-cleaning process of the mopping assembly 100, the water outlet holes 68 on the water distribution plate 66 distribute clean water and inject it into the cleaning assembly 20. The water equalizing strip 70 evenly wets the cleaning member 74 in cooperation with the rotation of the cleaning member 74, saving the self-cleaning time to a certain extent.

[0133] Thus, the water equalizing strip 70 can evenly wet the entire cleaning member 74 in cooperation with the rotation of the cleaning member 74 for the clean water distributed by the water distribution plate 66. This can ensure that when the cleaning member 74 contacts the ground, the entire cleaning member 74 is covered with clean water, thus avoiding the phenomenon that the area near the water outlet hole 68 is overly wet while the area far from the water outlet hole 68 remains dry. Please refer to Figure 5 , the water equalizing strip 70 is in a long strip shape. It can be understood that in other embodiments, the water equalizing strip 70 can be in a serrated shape.

[0134] The present utility model does not specifically limit the material of the water equalizing strip 70. In one example, the material of the water equalizing strip can be rubber, polyurethane, rust-proof latex, or the like.

[0135] The interference fit connection between the water equalizing strip 70 and the cleaning assembly 20 means that the water equalizing strip 70 can be mutually extruded with the cleaning member 74, facilitating the water equalizing strip 70 to evenly wet the cleaning member 74 with clean water. Optionally, in one embodiment, the extrusion amount between the water equalizing strip 70 and the cleaning member 74 is less than the thickness of the cleaning member 74, making the rotation resistance of the cleaning assembly 20 small.

[0136] In the embodiment of the present utility model, please refer to Figure 5 , the length direction of the second bracket 36 is the left-right direction. The water equalizing strip 70 continuously protrudes on the surface of the second bracket 36 facing the accommodation cavity 10, which means that the water equalizing strip 70 is continuously installed on the surface of the second bracket 36 along the length direction of the second bracket 36.

[0137] In other embodiments, the water equalizing strip 70 can be intermittently protruded on the surface of the second bracket 36 facing the accommodation cavity 10, which means that the water equalizing strip 70 is divided into multiple segments, and the multiple segments of the water equalizing strip 70 are intermittently installed on the surface of the second bracket 36 along the length direction of the second bracket 36. The number of the water equalizing strips 70 can be specifically limited according to actual needs, and the present utility model does not specifically limit this.

[0138] Therefore, since the multiple water outlet holes 68 are evenly arranged along the length direction of the mopping assembly 100, when the water box 12 is self-cleaned, the water injected by the water distribution plate 66 can quickly and evenly wet the cleaning member 74. Moreover, the interference fit connection between the water equalizing strip 70 and the cleaning assembly 20 can effectively improve the effect of quickly and evenly wetting the cleaning member 74 and save the self-cleaning time.

[0139] In some embodiments, please refer to Figure 1 , the mopping and washing assembly 100 further includes a second driving assembly 64, the cleaning assembly 20 further includes a rotating shaft 72 and a cleaning member 74, the cleaning member 74 is sleeved outside the rotating shaft 72, and the second driving assembly 64 is connected to the rotating shaft 72 and configured to drive the rotating shaft 72 to rotate so as to drive the cleaning member 74 to rotate.

[0140] In this way, the second driving assembly 64 can drive the rotating shaft 72 to rotate so as to drive the cleaning member 74 to rotate, so that the cleaning member can evenly cover and clean the ground.

[0141] Among them, after the second motor in the second driving assembly 64 is powered on, it performs a rotational motion, and the rotational force is transmitted to the rotating shaft 72 connected to the second driving assembly 64 through a transmission member, driving the rotating shaft 72 to perform a rotational motion, thereby driving the cleaning member 74 to rotate, so that the cleaning assembly 20 can clean the ground.

[0142] Specifically, in the embodiment of the present invention, the second driving assembly 58 adopts a driving method of a motor. It can be understood that in other embodiments, the second driving assembly 58 can also adopt a hydraulic driving method or a cylinder driving method.

[0143] Please refer to Figure 1 , the second driving assembly 64 includes a second motor and a transmission member. The second motor belongs to a rotating motor, and the transmission member 62 includes a screw. After the second motor is powered on, it performs a rotational motion, and the rotational force is transmitted to a nut through the screw, and the nut moves along the axial direction of the screw, driving the driving rotating shaft 72 fixedly connected to the nut to perform a rotational motion, thereby driving the cleaning member 74 to rotate. In other embodiments, the second motor can adopt a linear motor. The type of the second motor of the second driving assembly 64 can be specifically defined according to actual needs, and the present invention does not make specific limitations on this. In other embodiments, the transmission member of the second driving assembly 64 can adopt a gear transmission. After the motor is powered on, it performs a rotational motion, and the power is transmitted to the rotating shaft 72 connected to the gear through gear meshing, so that the rotating shaft 72 performs a rotational motion, thereby driving the cleaning member 74 to rotate. The type of the transmission member of the second driving assembly 64 can be specifically defined according to actual needs, and the present invention does not make specific limitations on this.

[0144] The cleaning assembly 20 further includes a bracket. The rotating shaft 72 is rotatably arranged on the bracket, and the cleaning member 74 is sleeved outside the bracket. The cleaning member 74 is sleeved outside the rotating shaft 72. The cleaning member 74 can be a mop with relatively good water absorption ability and has certain wear-resistant characteristics. By rotating the rotating shaft 72, the cleaning member 74 rubs and cleans on the ground. The water injected by the water dividing plate 66 quickly and evenly wets the cleaning member 74 through the water equalizing strip 70. When the cleaning member 74 rubs and cleans the ground and generates dirt, the rotating shaft 72 rotates to enable the cleaning member 74 to contact the water scraping part 16. The water scraping part 16 cooperates with the rotation of the cleaning assembly 20 to squeeze out the sewage generated by the cleaning member 74. The sewage squeezed out by the water scraping part 16 flows into the water box 12. By continuously spraying clean water onto the cleaning member 74 on the rotating shaft 72 through the water dividing plate 66, and the water scraping part 16 squeezing out the sewage generated after the cleaning member 74 rubs and cleans the ground, the cleaning member 74 can be kept clean at all times, avoiding the cleaning member 74 continuously rubbing the ground in a dirty state and causing secondary pollution to the ground, and there is no need to frequently remove the cleaning member 74 for cleaning and replacement, realizing self-cleaning, and improving the endurance of the cleaning work of the cleaning member 74.

[0151] (c) There is a water-dripping prevention part 22 below the water scraping part 16 of the water box 12. The water-dripping prevention part 22 can effectively block the sewage above the water-dripping prevention part 22, and the sewage is carried away by the cleaning member 74 and sucked away.

[0152] (d) The water scraping part 16 of the water box 12 is inclined from both sides to the middle, and the residual water on the water scraping part 16 can converge to the middle; there are connecting parts 24 with an outward-to-inward guiding structure on both sides of the water scraping part 16. When the self-moving cleaning robot 200 is overturned or tilted, the connecting parts 24 can prevent the sewage from leaking to both sides, and the sewage is sucked away by the cleaning member 74 on the water scraping part 24 and the water-dripping prevention part 22.

[0153] (e) There is a certain distance arrangement between two adjacent water outlet holes 17 on the water distribution plate 66, and a water equalizing strip 70 is added behind the rotation direction of the cleaning member 74, which can effectively solve the problem of quickly and evenly wetting the mop and save the time of self-cleaning.
