[0031] Please seeFigures 1 to 4 , Figure 1 is a structural schematic diagram of an embodiment of the cleaning system provided in the present application; Figure 2 is a partial structural schematic diagram of an embodiment of the cleaning device provided in the present application;

[0032] Figure 3 is a partial structural schematic diagram of a first embodiment of the sewage tank provided in the present application; Figure 4 is a partial structural schematic diagram of a second embodiment of the sewage tank provided in the present application. The present application provides a sewage tank 101 of a cleaning device 100. The sewage tank 101 comprises a tank assembly 10 and a tank cover assembly 20. The tank assembly 10 forms a containing cavity 111 with an opening 111a. The tank cover assembly 20 is arranged at the opening 111a. The tank cover assembly 20 is provided with a spraying flow channel 21, and a side of the tank cover assembly 20 facing the containing cavity 111 is provided with a spraying opening 211 in communication with the spraying flow channel 21, so that the spraying opening 211 faces the containing cavity 111.

[0033] The cleaning device 100 can be a scrubber, a mop, a window cleaner, etc., but is not limited thereto. The sewage tank 101 is arranged on the cleaning device 100 and is used to collect sewage generated in the process of cleaning a surface to be cleaned by the cleaning device 100. Specifically, the containing cavity 111 of the tank assembly 10 is used to suck in sewage generated on the surface to be cleaned and / or a cleaning mechanism 102 of the cleaning device 100 in the process of cleaning. The cleaning mechanism 102 is usually used to roll or move on the surface to be cleaned to clean the surface to be cleaned. The cleaning mechanism 102 can be a brush, a mop, a roller brush, etc., but is not limited thereto.

[0034] In some embodiments, please continue to refer to Figure 4 The tank assembly 10 is provided with a sewage suction flow channel 113 in communication with the containing cavity 111, so that the sewage generated in the process of cleaning the surface to be cleaned by the cleaning device 100 is sucked into the containing cavity 111 through the sewage suction flow channel 113, so as to improve the cleaning effect of the cleaning device 100 on the surface to be cleaned. A suction assembly can be arranged in the containing cavity 111 or the sewage suction flow channel 113, and the containing cavity 111 is formed with a negative pressure by the suction assembly, so as to suck the sewage on the surface to be cleaned into the containing cavity 111. The suction assembly can be a water pump, an electric pump, a pressure increasing valve, an electromagnetic valve, etc., but is not limited thereto.

[0035] In some embodiments, the box assembly 10 is provided with a sewage outlet (not shown) in communication with the containing cavity 111. After the cleaning device 100 finishes cleaning the surface to be cleaned and / or after the self-cleaning of the containing cavity 111 by the sewage tank 101 is finished, the sewage in the containing cavity 111 can be discharged through the sewage outlet. The sewage outlet can directly discharge the sewage in the containing cavity 111 to the sewer, or the sewage in the containing cavity 111 can be sucked into a sewage collection tank inside the base station 200 through the sewage outlet after the cleaning device 100 is docked with the base station 200.

[0036] The box cover assembly 20 can be sealingly connected with the inner wall of the opening 111a of the containing cavity 111, which not only prevents the sewage in the containing cavity 111 and the cleaning liquid sprayed by the spray port 211 towards the containing cavity 111 from leaking from the opening 111a of the containing cavity 111, but also prevents the pressure in the containing cavity 111 from being destroyed due to air leakage of the containing cavity 111, thereby preventing the containing cavity 111 from being unable to suck in sewage and other risks.

[0037] In some embodiments, the sewage tank 101 further comprises a plastic ring sealingly arranged between the box assembly 10 and the inner wall of the opening 111a, which can improve the sealing effect of the box cover assembly 20 on the opening 111a. The plastic ring can be made of a material with good wear resistance, weather resistance and chemical stability. For example, the material of the plastic ring can be silicone rubber, fluorosilicone rubber (FLS), ethylene-propylene-diene monomer (EPDM) or nitrile butadiene rubber (NBR), but is not limited thereto.

[0038] The spray flow channel 21 arranged on the box cover assembly 20 is used to contain cleaning liquid, and the spray flow channel 21 is in communication with the containing cavity 111 through the spray port 211 to spray the cleaning liquid towards the containing cavity 111 through the spray port 211. The cleaning liquid can be pure tap water or tap water added with one or more cleaning components such as a suction aid, a surfactant, a solubilizer, deionized water, a defoaming agent, etc.

[0039] By arranging the spray flow channel 21 on the box cover assembly 20, and arranging the spray port 211 which communicates with the spray flow channel 21 on the side of the box cover assembly 20 facing the containing cavity 111, so that the spray port 211 faces the containing cavity 111, so that the cleaning liquid in the spray flow channel 21 can be sprayed out through the spray port 211 towards the containing cavity 111 to clean the containing cavity 111. On the one hand, the arrangement of the spray flow channel 21 and the spray port 211 is not affected by whether the sewage tank 101 is in the state of sucking sewage, compared with the scheme of cleaning the containing cavity 111 by sucking sewage in the related art, and the cleaning time can be flexibly selected, thereby improving the flexibility and convenience of self-cleaning of the sewage tank 101. On the other hand, the cleaning liquid in the spray flow channel 21 can be directly sprayed to the containing cavity 111 through the spray port 211, so that the impact force of the cleaning liquid sprayed out of the spray port 211 is larger, which can enhance the cleaning intensity and cleaning range of the cleaning liquid on the inner wall of the containing cavity 111, thereby improving the self-cleaning effect and self-cleaning efficiency of the sewage tank 101.

[0040] Please see Figure 5 , Figure 5 is a part structure schematic diagram of the third embodiment of the sewage tank provided in the present application. In some embodiments, the box cover assembly 20 is further provided with a liquid inlet port 212 which communicates with the spray flow channel 21, and the box body assembly 10 is further provided with a clean water flow channel 112, and the outlet of the clean water flow channel 112 communicates with the liquid inlet port 212.

[0041] In some embodiments, the box body assembly 10 is further formed with a first clean water tank (not shown in the figure) which is isolated from the containing cavity 111, and the first clean water tank is used to contain cleaning liquid. During the process of cleaning the surface to be cleaned by the cleaning device 100, the cleaning liquid in the first clean water tank can flow to the surface to be cleaned or the cleaning mechanism 102 through the water pipe, so as to wet the surface to be cleaned or the cleaning mechanism 102, so as to help dissolve the dirt on the surface to be cleaned. The cleaning mechanism 102 will roll or move to remove the dirt on the surface to be cleaned by friction.

[0042] The inlet of the clean water flow channel 112 can communicate with the first clean water tank, so as to guide the cleaning liquid in the first clean water tank into the spray flow channel 21 through the clean water flow channel 112; or the inlet of the clean water flow channel 112 can also be used to communicate with a second clean water tank on the base station 200 for containing cleaning liquid, so as to guide the cleaning liquid in the second clean water tank into the spray flow channel 21 through the clean water flow channel 112; or the inlet of the clean water flow channel 112 can also be used to connect a faucet of tap water, so as to guide the tap water into the spray flow channel 21.

[0043] By connecting the outlet of the clean water flow channel 112 with the liquid inlet 212 of the communication spray flow channel 21, the cleaning liquid is guided into the spray flow channel 21 through the clean water flow channel 112, so that the cleaning liquid in the spray flow channel 21 is free of impurities or has fewer impurities compared to the related art solution of cleaning the containing cavity 111 by sucking in the sewage, which not only does not affect the flow direction and flow rate of the cleaning liquid sprayed from the spray port 211, but also effectively enhances the cleaning strength and cleaning effect of the cleaning liquid on the inner wall of the containing cavity 111, and avoids impurities adhering to the inner wall of the containing cavity 111, thereby further improving the self-cleaning effect of the sewage tank 101.

[0044] In some embodiments, referring to Figure 2 , Figure 4 and Figure 5 , the tank assembly 10 comprises a shell 11. The shell 11 forms the containing cavity 111 and the clean water flow channel 112 which is isolated from the containing cavity 111 and extends from the side of the shell 11 away from the opening 111a to the opening 111a. The liquid inlet 212 is located on the side of the tank cover assembly 20 facing the containing cavity 111.

[0045] The containing cavity 111 and the clean water flow channel 112 can be formed on the shell 11 by injection molding, extrusion molding or blow molding, but are not limited thereto.

[0046] The outlet of the clean water flow channel 112 is sealingly connected with the liquid inlet 212. On the one hand, it can prevent the sewage in the containing cavity 111 from flowing into the spray flow channel 21 from the outlet of the clean water flow channel 112 and the liquid inlet 212, thereby maintaining the cleanliness of the cleaning liquid in the spray flow channel 21 and preventing the cleaning liquid in the spray flow channel 21 from being contaminated. On the other hand, it can also prevent the cleaning liquid in the clean water flow channel 112 from directly flowing into the containing cavity 111 from the outlet of the clean water flow channel 112 and the liquid inlet 212, thereby avoiding the risk of insufficient flushing force of the cleaning liquid sprayed from the spray port 211 due to air leakage of the clean water flow channel 112 and leakage of the cleaning liquid, and helping to improve the cleaning effect of the cleaning liquid on the containing cavity 111 and avoiding waste of the cleaning liquid.

[0047] The water inlet 212 is arranged on the side of the tank cover assembly 20 facing the containing cavity 111, and the clean water flow channel 112 extends from the side of the shell 11 away from the opening 111a to the opening 111a and communicates with the water inlet 212, so that the extension direction of the clean water flow channel 112 is perpendicular to or intersects with the plane on which the side of the tank cover assembly 20 facing the containing cavity 111 is located, the path of the clean water flow channel 112 can be shortened, the cleaning liquid can flow smoothly along the clean water flow channel 112 into the spray flow channel 21, thereby effectively shortening the time length of the cleaning liquid flowing along the clean water flow channel 112 to the spray flow channel 21, and facilitating the increase of the pressure of the cleaning liquid in the spray flow channel 21, which can not only improve the cleaning efficiency of the cleaning liquid sprayed from the spray port 211 on the containing cavity 111, but also enhance the flushing intensity of the cleaning liquid on the inner wall of the containing cavity 111, thereby improving the cleaning effect of the cleaning liquid sprayed from the spray port 211 on the containing cavity 111.

[0048] In some embodiments, please refer to 3 and Figure 5 The spray flow channel 21 includes a first spray flow channel 21a, and the tank cover assembly 20 includes a cover plate 22 and a connecting piece 23. The cover plate 22 is arranged at the opening 111a, and the side of the cover plate 22 away from the containing cavity 111 is provided with an annular groove 221 arranged around the outer peripheral region of the cover plate 22. The connecting piece 23 is arranged on the side of the cover plate 22 away from the containing cavity 111 and covers the slot opening 221a of the annular groove 221 to form the first spray flow channel 21a.

[0049] The annular groove 221 can be a recess formed by the cover plate 22 being concave in the direction facing the containing cavity 111, and the annular groove 221 is located on the outer peripheral region of the cover plate 22 close to the inner side wall 1111 of the containing cavity 111. The inner side wall 1111 of the containing cavity 111 surrounds the annular groove 221. The slot opening 221a of the annular groove 221 is located on the side of the cover plate 22 away from the containing cavity 111, and the connecting piece 23 is arranged on the side of the cover plate 22 away from the containing cavity 111 and covers the slot opening 221a of the annular groove 221 to seal the slot opening 221a of the annular groove 221, so that the first spray flow channel 21a formed is in a relatively closed environment. On the one hand, it can avoid the risk of damage to other components outside the sewage tank 101 due to the immersion or soaking of the cleaning liquid from the first spray flow channel 21a leaking from the slot opening 221a of the annular groove 221, thereby effectively improving the performance and service life of the cleaning equipment 100; on the other hand, it can avoid the influence of the pressure in the first spray flow channel 21a due to the unsealed slot opening 221a of the annular groove 221, thereby effectively enhancing the impact force of the cleaning liquid on the inner wall of the containing cavity 111, further improving the self-cleaning effect of the sewage tank 101.

[0050] In some embodiments, as Figure 5As shown, the bottom of the annular groove 221 is provided with a plurality of spray openings 211 which are in communication with the accommodating cavity 111 and are arranged at intervals.

[0051] The plurality of spray openings 211 can be arranged at intervals along the bottom of the annular groove 221 in a uniform arrangement, or can be arranged at intervals along the bottom of the annular groove 221 in a non-uniform arrangement. The number of spray openings 211 can be 4, 6, 8, 12, 15, 18, 24, etc., but is not limited thereto, and the number of spray openings 211 can be selected according to the flow area of the spray openings 211 and the size of the annular groove 221 in the circumferential direction.

[0052] By arranging the plurality of spray openings 211 at intervals along the bottom of the annular groove 221 which are in communication with the accommodating cavity 111, the cleaning liquid in the first spray flow channel 21a can be sprayed toward the accommodating cavity 111 along the bottom of the annular groove 221, which not only improves the uniformity of the cleaning liquid sprayed from the spray openings 211, but also improves the coverage area of the cleaning liquid sprayed from the spray openings 211, thereby expanding the flushing area of the cleaning liquid toward the inner wall of the accommodating cavity 111, effectively removing dirt attached to the inner wall of the accommodating cavity 111, reducing the cleaning dead angle, and effectively improving the cleaning efficiency and cleaning effect of the cleaning liquid sprayed from the spray openings 211 on the accommodating cavity 111.

[0053] In some embodiments, at least part of the spray openings 211 are directed toward the inner side wall 1111 adjacent to the accommodating cavity 111, and the central axis of the spray openings 211 intersects the inner side wall 1111.

[0054] Specifically, the spray openings 211 are directed away from the middle region of the accommodating cavity 111, so that the spray openings 211 can spray cleaning liquid toward the inner side wall 1111 closest to the accommodating cavity 111, and the central axis of the spray openings 211 intersects the inner side wall 1111. The inner side wall 1111 adjacent to the spray openings 211 is the inner side wall 1111 closest to the spray openings 211.

[0055] By directing at least part of the spray openings 211 toward the inner side wall 1111 adjacent to the accommodating cavity 111, and arranging the central axis of the spray openings 211 to intersect the inner side wall 1111, not only can the cleaning liquid sprayed from the spray openings 211 more effectively contact the inner side wall 1111 of the accommodating cavity 111, but also can the cleaning liquid be sprayed at a higher intensity and flow rate toward the inner side wall 1111 of the accommodating cavity 111 to flush out the dirt attached to the inner side wall 1111 of the accommodating cavity 111, thereby not only improving the cleaning effect of the cleaning liquid sprayed from the spray openings 211 on the accommodating cavity 111, but also reducing the cleaning time and consumption of cleaning liquid for the accommodating cavity 111.

[0056] Please refer to Figures 6 to 7 , Figure 6 is a partial structural schematic diagram of a fourth embodiment of the sewage tank provided in the present application, Figure 7 is a cross-sectional structural schematic diagram of an embodiment of the spray arm of the sewage tank provided in the present application. In some embodiments, the sewage tank 101 further comprises a spray arm 30. The spray arm 30 is rotatably connected to the side of the tank cover assembly 20 facing the containing cavity 111, and the spray arm 30 is provided with a shunt flow channel 31 communicating with the spray opening 211. The side of the spray arm 30 away from the tank cover assembly 20 is provided with a plurality of sub-spray openings 211a communicating with the shunt flow channel 31 and arranged along the extension direction of the shunt flow channel 31.

[0057] Among them, the spray arm 30 is arranged at the spray opening 211 and is sealingly connected with the spray opening 211, and can rotate relative to the tank cover assembly 20 under the action of the backwash force of the cleaning liquid sprayed from the spray opening 211. The number of spray arms 30 can be one. Of course, the number of spray arms 30 can also be multiple, for example, the number of spray arms 30 can also be two, 4, 5, 6, 8, etc. but not limited to this, the specific number of spray arms 30 can be selected according to the volume of the containing cavity 111.

[0058] When the cleaning liquid in the first spray flow channel 21a is sprayed from the spray opening 211, a backwash force will be generated on the spray arm 30. This backwash force will drive the spray arm 30 to rotate, so as to automatically change the spray angle of the spray opening 211, so that each area inside the containing cavity 111 can be fully cleaned, thereby achieving comprehensive cleaning of the containing cavity 111. Not only can improve the cleaning efficiency of the cleaning liquid sprayed from the spray opening 211 on the containing cavity 111, but also can reduce the time required for cleaning the containing cavity 111.

[0059] In some embodiments, the spray arm 30 is rotatably connected to the side of the tank cover assembly 20 facing the containing cavity 111, and the whole spray arm 30 rotates relative to the tank cover assembly 20 under the backwash force of the sprayed cleaning liquid; or, a part of the spray arm 30 can be fixed to the side of the tank cover assembly 20 facing the containing cavity 111 by screwing, interference connection or the like, and the other part of the spray arm 30 is rotatably connected to the end of the part of the spray arm 30 away from the tank cover assembly 20, and is provided with the spray opening 211 and the shunt channel communicating with the spray opening 211. Under the backwash force of the sprayed cleaning liquid, the part of the spray arm 30 remains stationary relative to the tank cover assembly 20, and the other part of the spray arm 30 can rotate relative to the tank cover assembly 20.

[0060] By setting the shunt flow channel 31 in communication with the spray port 211 in the spray arm 30, the shunt flow channel 31 can uniformly distribute the cleaning liquid in the first spray flow channel 21a to each sub-spray port 211a, ensuring that each sub-spray port 211a can pass through sufficient and stable cleaning liquid, and the uniformity of the cleaning liquid sprayed from the plurality of sub-spray ports 211a can be improved.

[0061] The plurality of sub-spray ports 211a are arranged at intervals along the extension direction of the shunt flow channel 31. Due to the rotation of the spray arm 30 under the impact of the cleaning liquid, the plurality of sub-spray ports 211a are at different spray positions, and the spray angles of the plurality of sub-spray ports 211a can also be different, so that the spray arm 30 can clean multiple areas of the containing cavity 111, which helps to improve the cleaning efficiency and cleaning effect of the cleaning liquid sprayed from the spray port 211 on the containing cavity 111.

[0062] In some embodiments, the spray arm 30 includes a connecting portion and a main body portion rotatably connected to the connecting portion, and the connecting portion communicates the spray flow channel and the shunt flow channel 31. The connecting portion can be fixed to one side of the box cover assembly 20 facing the containing cavity 111 by thread fixing, interference connection or the like. The spray port 211 and the shunt flow channel 31 are provided on the main body portion. When the cleaning liquid in the first spray flow channel 21a is sprayed from the spray port 211, a back impact force will be generated on the main body portion, which will drive the main body portion to rotate to automatically change the spray angle of the spray port 211.

[0063] In some embodiments, the rotation plane of the spray arm 30 is perpendicular to the arrangement direction of the box cover assembly 20 and the box body assembly 10, so that the cleaning liquid sprayed from the spray port 211 of the spray arm 30 can more uniformly contact every corner of the containing cavity 111 during rotation, so that the spray range of the cleaning liquid sprayed from the spray port 211 of the spray arm 30 is larger, and the number of spray arms 30 can be reduced under the premise of expanding the cleaning range and improving the cleaning efficiency, thereby reducing the production cost.

[0064] In some embodiments, the rotation plane of the spray arm 30 can also be parallel to the arrangement direction of the box cover assembly 20 and the box body assembly 10, and the spray port 211 of the spray arm 30 faces the inner side wall 1111 of the containing cavity 111.

[0065] In some embodiments, the central axis of at least part of the sub-spray ports 211a intersects the inner side wall 1111 of the containing cavity 111.

[0066] By intersecting the central axis of the spray port 211 with the inner side wall 1111 of the accommodation cavity 111, the cleaning liquid sprayed from the spray port can directly impact the inner side wall 1111 of the accommodation cavity 111. On the one hand, the impact force of the cleaning liquid on the spray arm 30 is stronger, which can improve the rotation rate and rotation intensity of the spray arm 30, thereby improving the cleaning efficiency and cleaning effect of the spray arm 30 on the accommodation cavity 111. On the other hand, the impact force of the cleaning liquid on the water flow in the accommodation cavity 111 is enhanced, which helps to better remove dirt attached to the inner side wall 1111 of the accommodation cavity 111.

[0067] In some embodiments, please refer to Figure 3 and Figure 5 , the spray channel 21 further comprises a second spray channel 21b. The side of the cover plate 22 facing the accommodation cavity 111 is provided with a baffle 51 and a probe support 52, and the baffle 51 and / or the probe support 52 form the second spray channel 21b and the spray port 211 communicating with the second spray channel 21b.

[0068] The second spray channel 21b can be directly formed in the interior of the baffle 51 and / or the probe support 52; alternatively, the second spray channel 21b can be a separate component arranged on the baffle 51 and / or the probe support 52. The second spray channel 21b communicates with the first spray channel 21a. The spray port 211 communicating with the second spray channel 21b can face the inner wall of the accommodation cavity 111, and the central axis of the spray port 211 is arranged to intersect the inner side wall 1111.

[0069] In some embodiments, the cover plate 22 is detachably arranged at the opening 111a. The baffle 51 is located at the sewage inlet 113a of the accommodation cavity 111, and the baffle 51 can guide the sewage flowing out of the sewage inlet 113a to flow into the accommodation cavity 111.

[0070] The sewage tank 101 further comprises a detection assembly 60 mounted on the probe support 52 or the baffle 51. The detection assembly 60 is used to detect the water level in the accommodation cavity 111. When the water level in the accommodation cavity 111 reaches a preset water level, the detection assembly 60 will send a reminder signal to make the cleaning device 100 automatically move to a specified position to discharge the sewage in the accommodation cavity 111, or to remind the user to manually discharge the sewage in the accommodation cavity 111 in time.

[0071] In some embodiments, the detection assembly 60 can detect the water level in each cleaning posture of the cleaning device 100, so that the cleaning device 100 performs the cleaning task in each cleaning posture, and the sewage in the accommodation cavity 111 will not flow back to the surface to be cleaned through the sewage inlet 113a and the sewage suction channel 113. The cleaning postures of the cleaning device 100 include but are not limited to the upright cleaning posture, the flat lying cleaning posture, and the inclined lying cleaning posture between the upright cleaning posture and the flat lying cleaning posture.

[0072] Please refer to Figure 8 , Figure 8 is part of the structure schematic diagram of another embodiment of the cleaning device provided by the present application. In some embodiments, the sewage tank 101 further comprises a first pressurizing assembly 40. The first pressurizing assembly 40 is arranged in the spraying flow channel 21 and / or the clean water flow channel 112.

[0073] When the first pressurizing assembly 40 is arranged in the spraying flow channel 21, the first pressurizing assembly 40 can be arranged in the first spraying flow channel 21a or the second spraying flow channel 21b. When the first pressurizing assembly 40 is arranged in the clean water flow channel 112, the first pressurizing assembly 40 can be arranged at one end of the clean water flow channel 112 close to the first spraying flow channel 21a, or at one end of the clean water flow channel 112 away from the first spraying flow channel 21a, or in the region close to the middle of the clean water flow channel 112.

[0074] The first pressurizing assembly 40 can be a water pump, an electric pump, a pressure increasing valve or an electromagnetic valve, but is not limited thereto.

[0075] By arranging the first pressurizing assembly 40 in the spraying flow channel 21 and / or the clean water flow channel 112, the cleaning liquid can be sprayed out of the spraying port 211 at a higher speed and with a stronger impact force, which helps to improve the cleaning efficiency and cleaning effect of the containing cavity 111.

[0076] Please continue to refer to Figures 1 to 2 The present application further provides a cleaning device 100. The cleaning device 100 comprises a cleaning mechanism 102, a machine body 103 and a sewage tank 101. The machine body 103 is rotatably arranged on the cleaning mechanism 102, and the sewage tank 101 is detachably arranged on the machine body 103. The sewage tank 101 adopts any one of the sewage tanks 101 described above. The cleaning mechanism 102 is located at the lower end of the machine body 103, and is usually used to move on the surface to be cleaned for cleaning work. The machine body 103 can rotate relative to the cleaning mechanism 102 to adapt to different cleaning scenes, such as cleaning the bottom of a bed, the bottom of a sofa and other sanitary dead angles, and the machine body 103 needs to be laid flat. Therefore, by rotating the machine body 103 relative to the cleaning mechanism 102, the cleaning device 100 at least has an upright cleaning posture, a flat cleaning posture and an inclined cleaning posture between the upright cleaning posture and the flat cleaning posture, which is beneficial to the cleaning of different areas by the cleaning device 100. With the rotation of the machine body 103, the sewage tank 101 has an upright state, a flat state and an inclined state.

[0077] Please continue to refer to Figure 1The application further provides a cleaning system 1000. The cleaning system 1000 comprises the cleaning device 100 and the base station 200. The cleaning device 100 comprises the cleaning mechanism 102, the body 103 and the sewage tank 101. The body 103 is rotatably arranged on the cleaning mechanism 102. The sewage tank 101 is detachably arranged on the body 103. The sewage tank 101 is any one of the sewage tanks 101 in the above embodiments. The cleaning device 100 cooperates with the base station 200 when the cleaning device 100 is docked with the base station 200.

[0078] In some embodiments, the base station 200 is provided with a water supply channel and a second pressurizing assembly arranged in the water supply channel. The water supply channel is in communication with the clean water channel 112 of the sewage tank 101 when the cleaning device 100 is docked with the base station 200. The base station 200 pressurizes the cleaning liquid and supplies the pressurized cleaning liquid to the sewage tank 101.

[0079] The base station 200 pressurizes the cleaning liquid in the water supply channel through the second pressurizing assembly to supply the pressurized cleaning liquid to the sewage tank 101. In this way, the cleaning liquid can be sprayed from the spray port 211 at a higher speed and with a stronger impact, which helps to improve the cleaning efficiency and cleaning effect of the containing cavity 111. The second pressurizing assembly can be a water pump, an electric pump, a pressure valve or an electromagnetic valve, but is not limited thereto.

[0080] In some embodiments, the base station 200 can monitor the power of the cleaning device 100, provide charging service for the cleaning device 100, and clean the cleaning components of the cleaning device 100.

[0081] In the embodiments of the application, the spray channel 21 is arranged on the tank cover assembly 20, and the spray port 211 in communication with the spray channel 21 is arranged on the side of the tank cover assembly 20 facing the containing cavity 111, so that the spray port 211 faces the containing cavity 111. Therefore, the cleaning liquid in the spray channel 21 can be sprayed towards the containing cavity 111 through the spray port 211 to clean the containing cavity 111. On the one hand, the arrangement of the spray channel 21 and the spray port 211 is not affected by whether the sewage tank 101 is in the state of sucking sewage, compared with the scheme of cleaning the containing cavity 111 by sucking sewage in the related art, and the cleaning time can be flexibly selected, thereby improving the flexibility and convenience of self-cleaning of the sewage tank 101. On the other hand, the cleaning liquid in the spray channel 21 can be directly sprayed towards the containing cavity 111 through the spray port 211, so that the impact force of the cleaning liquid sprayed from the spray port 211 is larger, which can enhance the cleaning strength and cleaning range of the cleaning liquid on the inner wall of the containing cavity 111, thereby improving the self-cleaning effect and self-cleaning efficiency of the sewage tank 101.
