In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally also include steps or units that are not listed, or may optionally also include other steps or units inherent to these processes, methods, products or devices.

[0030] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] See also Figure 1-Figure 7 The present application provides a sewage tank 100, which includes a cover body 10 and a box body 20. The cover body 10 and the box body 20 are detachably connected. That is, the present application greatly facilitates the early assembly and later maintenance of the sewage tank 100 by setting the sewage tank 100 as two parts of the cover body 10 and the box body 20 that are detachably connected.

[0032] See also Figure 1-Figure 3 , Figure 1 1 is a structural diagram of an embodiment of the cover 10 of the sewage tank 100 provided in this application. Figure 2 This is a side structural diagram of another embodiment of the sewage tank 100 provided in this application. Figure 3 yes Figure 2 The schematic diagram of the top view of the box body 20 in the sewage tank 100 is shown.

[0033] like Figure 1-Figure 3As shown, the cover body 10 is provided with a sewage inlet 11 and a sewage outlet 12. The sewage inlet 11 is connected to the housing 20 via a first sewage inlet pipe 30, and the sewage outlet 12 is connected to the housing 20 via a first sewage outlet pipe 40. Based on this, when sewage is introduced, the present application can directly introduce sewage into the first sewage inlet pipe 30 inside the sewage tank 100 through the sewage inlet 11, and then guide the sewage into the housing 20. When sewage is discharged, the present application can directly guide the sewage to the sewage outlet 12 through the first sewage outlet pipe 40, and then discharge the sewage to the outside of the sewage tank 100. In summary, while realizing the automatic sewage inlet and discharge functions of the sewage tank 100, the present application greatly simplifies the internal structure of the sewage tank 100, thereby saving the internal space of the sewage tank 100 and improving the utilization rate of the sewage tank 100.

[0034] like Figure 2 As shown, in one embodiment of the present application, the first sewage inlet pipe 30 includes a first sewage inlet sub-pipe section 31 and a second sewage inlet sub-pipe section 32 that are interconnected. The sewage inlet 11 is sequentially connected to the first sewage inlet sub-pipe section 31 and the second sewage inlet sub-pipe section 32. In other words, after sewage flows from the sewage inlet 11 into the first sewage inlet sub-pipe section 31, it is then guided into the housing 20 through the second sewage inlet sub-pipe section 32. This ensures that after sewage enters the sewage tank 100 from the sewage inlet 11, it is continuously guided by a pipe until it reaches the interior of the housing 20. This prevents splashing and water impacting the bottom and side walls of the sewage tank 100 when sewage directly enters the sewage tank 100, thereby preventing damage to the internal structure of the sewage tank 100 and extending the service life of the sewage tank 100.

[0035] It is worth noting that in some cases, the first sewage inlet sub-pipe section 31 is connected to the sewage inlet port 11 on the cover body 10, and one end of the second sewage inlet sub-pipe section 32 is connected to the first sewage inlet sub-pipe section 31, and the other end extends to the bottom of the box body 20 and is connected to the bottom of the box body 20.

[0036] To facilitate cleaning or replacement of the first sewage inlet sub-pipe segment 31 and the second sewage inlet sub-pipe segment 32, the first sewage inlet sub-pipe segment 31 and the second sewage inlet sub-pipe segment 32 can be configured to be detachably connected to the sewage tank 100. The specific connection method can be a snap connection, a threaded connection, etc., as long as the first sewage inlet sub-pipe segment 31 and the second sewage inlet sub-pipe segment 32 can be detachably connected to the sewage tank 100, and this application does not make specific restrictions here. It is worth noting that in this application, the first sewage inlet sub-pipe segment 31 and the second sewage inlet sub-pipe segment 32 can both be configured to be detachably connected to the sewage tank 100, or one of the first sewage inlet sub-pipe segment 31 and the second sewage inlet sub-pipe segment 32 can be configured to be detachably connected to the sewage tank 100, and the other can be configured to be fixedly connected to the sewage tank 100. The specific setting method can be adjusted according to user needs.

[0037] Specifically, in one embodiment of the present application, the first sewage inlet sub-pipe segment 31 can be configured to be fixedly connected to the cover body 10, so that the first sewage inlet sub-pipe segment 31 and the sewage inlet port 11 are always in fluid communication, avoiding the process troubles and assembly difficulties caused by the need to dock the first sewage inlet pipe 30 with the sewage inlet port 11 during assembly. The first sewage inlet sub-pipe segment 31 can even be configured to be integrally formed with the cover body 10, which can further avoid problems such as the first sewage inlet sub-pipe segment 31 falling off during later use. At the same time, the second sewage inlet sub-pipe segment 32 and the first sewage inlet sub-pipe segment 31 can be either fixedly connected or detachably connected. When the second sewage inlet sub-pipe segment 32 and the first sewage inlet sub-pipe segment 31 are detachably connected, the two can be connected by plugging, socketing, threading, etc. The specific connection method between the two is not limited, as long as they can be docked and the sewage can be smoothly transported from the sewage inlet port 11 to the interior of the box body 20.

[0038] Of course, in other embodiments of the present application, the first sewage inlet pipe 30 does not have a sub-pipeline, but instead extends directly from the lid 10 to the bottom of the tank 20. In this case, the first sewage inlet pipe 30 can be detachably connected to the lid 10, fixedly connected, or integrally formed with the lid 10. When the lid 10 is connected to the tank 20, the first sewage inlet pipe 30 extends directly into the bottom of the tank 20, directing sewage from the sewage inlet 11 to the bottom of the tank 20. This further simplifies the internal structure of the sewage tank 100, streamlines the assembly process of the sewage tank 100, and facilitates manufacturing.

[0039] In some embodiments of the present application, a filter screen 33 is provided at least partially within the first sewage inlet pipe 30. When sewage enters the first sewage inlet pipe 30, solid or semi-solid matter contained in the sewage is trapped on the filter screen 33 of the first sewage inlet pipe 30. Thus, the filter screen 33 of the first sewage inlet pipe 30 prevents solid or semi-solid matter from entering the interior of the sewage tank 100 from the cavity of the first sewage inlet pipe 30. When the sewage tank 100 is draining, solid or semi-solid matter within the cavity of the first sewage inlet pipe 30 can directly enter the first sewage outlet 40 and then be discharged from the sewage tank 100 through the sewage outlet 12. This makes it easier for solid or semi-solid matter contained in the sewage to be discharged. Furthermore, when the sewage tank 100 is storing sewage, solid or semi-solid matter is confined within the cavity of the first sewage inlet pipe 30, thereby preventing solid or semi-solid matter from adhering to the sidewalls of the sewage tank 100 and facilitating cleaning of the sewage tank 100.

[0040] For example, the first sewage inlet pipe 30 may be provided with filter screens 33 on all four sides or on only one side. The specific location and area of ​​the filter screens 33 can be determined based on actual conditions and are not specifically limited in this application. The filter screens 33 may be made of metal mesh or other materials, and the mesh shape may be circular, quadrilateral, elliptical, etc., as long as they can filter solid or semi-solid substances. This application does not specifically limit this.

[0041] In some cases, the first sewage inlet pipe 30 is provided with a first sewage inlet sub-pipe section 31 and a second sewage inlet sub-pipe section 32. In this case, the filter screen 33 can be provided on either the first sewage inlet sub-pipe section 31 or the second sewage inlet sub-pipe section 32, and this is not specifically limited in this application. If the filter screen 33 is provided on the second sewage inlet sub-pipe section 32, the second sewage inlet sub-pipe section 32 can be provided with a detachable structure to facilitate cleaning or replacement of the filter screen 33. For example, a pull-out chute (not shown) can be provided along the length direction of the second sewage inlet sub-pipe section 32 in the sewage tank 100, and a guide rail structure (not shown) that cooperates with the pull-out chute can be provided at a corresponding position of the second sewage inlet sub-pipe section 32, so that the second sewage inlet sub-pipe section 32 can be directly cleaned, disassembled or installed by pulling it up and down.

[0042] In other cases, the first sewage inlet pipe 30 is not provided with a sub-pipe, but rather a single pipe extending directly from the cover 10 to the bottom of the box body 20. In this case, the filter 33 can be installed at any position on the first sewage inlet pipe 30, for example, the filter 33 can be installed near the bottom of the side wall of the first sewage inlet pipe 30, near the middle of the side wall, or near the top of the side wall. The setting can be based on the actual needs of the user and is not specifically limited in this application.

[0043] In one embodiment of the present application, the first sewage pipe 40 includes a first sewage sub-pipe section 41 and a second sewage sub-pipe section 42, which are interconnected. The sewage outlet 12 is sequentially connected to the first sewage sub-pipe section 41 and the second sewage sub-pipe section 42. In other words, sewage within the tank 20 is drawn into the second sewage sub-pipe section 42, and further transported to the sewage outlet 12 via the first sewage sub-pipe section 41, from which it flows out of the sewage tank 100. As a result, the present application enables automatic sewage discharge, avoiding the need for manual cleaning of sewage within the sewage tank 100. This significantly improves the intelligence of the sewage tank 100 and enhances its ease of use.

[0044] It is worth noting that in some cases, the first sewage discharge sub-pipe section 41 is connected to the sewage discharge port 12 of the cover body 10, and one end of the second sewage discharge sub-pipe section 42 is connected to the first sewage discharge sub-pipe section 41, and the other end extends to the bottom of the box body 20 and is connected to the bottom of the box body 20.

[0045] In order to facilitate the cleaning or replacement of the first sewage discharge sub-pipe segment 41 and the second sewage discharge sub-pipe segment 42, the first sewage discharge sub-pipe segment 41 and the second sewage discharge sub-pipe segment 42 can be set to be detachably connected to the sewage tank 100. The specific connection method can be a snap connection, a threaded connection, etc., as long as the first sewage discharge sub-pipe segment 41 and the second sewage discharge sub-pipe segment 42 can be detachably connected to the sewage tank 100, this application does not make specific limitations here. It is worth noting that in this application, the first sewage discharge sub-pipe segment 41 and the second sewage discharge sub-pipe segment 42 can be both set to be detachably connected to the sewage tank 100, or one of the first sewage discharge sub-pipe segment 41 and the second sewage discharge sub-pipe segment 42 can be set to be detachably connected to the sewage tank 100, and the other can be set to be fixedly connected to the sewage tank 100. The specific setting method can be adjusted according to user needs.

[0046] Specifically, in one embodiment of the present application, the first sewage discharge sub-pipe segment 41 can be set to be fixedly connected to the cover body 10, so that the first sewage discharge sub-pipe segment 41 and the sewage outlet 12 are always fluidically connected, avoiding the process troubles and assembly difficulties caused by the need to dock the first sewage discharge sub-pipe segment 41 with the sewage outlet 12 during assembly. The first sewage discharge sub-pipe segment 41 can even be set to be integrally formed with the cover body 10, which can further avoid the problems of the first sewage discharge sub-pipe segment 41 falling off during later use. At the same time, the first sewage discharge sub-pipe segment 41 and the second sewage discharge sub-pipe segment 42 can be either fixedly connected or detachably connected. When the first sewage discharge sub-pipe segment 41 and the second sewage discharge sub-pipe segment 42 are detachably connected, the two can be connected by plugging, sleeve connection, threaded connection, etc. The specific connection method between the two is not limited, as long as they can be docked and the sewage can be smoothly transported from the box body 20 to the sewage outlet 12 and then discharged to the outside of the sewage tank 100.

[0047] Of course, in other embodiments of the present application, the first sewage pipe 40 does not have a sub-pipeline, but instead extends directly from the cover 10 to the bottom of the tank 20. In this case, the first sewage pipe 40 can be detachably connected to the cover 10, fixedly connected, or integrally formed with the cover 10. When the cover 10 is connected to the tank 20, the first sewage pipe 40 extends directly into the bottom of the tank 20, directing sewage directly from the bottom of the tank 20 to the sewage outlet 12. This further simplifies the internal structure of the sewage tank 100, streamlines the assembly process of the sewage tank 100, and facilitates manufacturing.

[0048] In summary, in one embodiment of the present application, a sewage inlet 11 and a sewage outlet 12 are provided on the cover body 10 of the sewage tank 100, and the first sewage inlet pipe 30 is provided with a first sewage inlet sub-pipe section 31 and a second sewage inlet sub-pipe section 32 that are connected to each other. The first sewage inlet sub-pipe section 31 is connected to the sewage inlet 11, and one end of the second sewage inlet sub-pipe section 32 is connected to the first sewage inlet sub-pipe section 31, and the other end extends to the bottom of the box body 20 and is connected to the bottom of the box body 20, so that the sewage can directly enter the bottom of the box body 20 from the sewage inlet 11 along the first sewage inlet sub-pipe section 31 and the second sewage inlet sub-pipe section 32. At the same time, the first sewage pipe 40 is provided with a first sewage sub-pipe section 41 and a second sewage sub-pipe section 42 that are connected to each other. The first sewage sub-pipe section 41 is connected to the sewage outlet 12 of the cover body 10, and one end of the second sewage sub-pipe section 42 is connected to the first sewage sub-pipe section 41, and the other end extends to the bottom of the box body 20 and is connected to the bottom of the box body 20, so that the sewage can enter the second sewage sub-pipe section 42 and the first sewage sub-pipe section 41 in turn from the bottom of the box body 20, and finally flow to the sewage outlet 12 through the first sewage sub-pipe section 41, and then flow out to the outside of the sewage tank 100.

[0049] In another embodiment of the present application, neither the first sewage inlet pipe 30 nor the first sewage outlet pipe 40 is provided with a sub-pipe. Instead, the first sewage inlet pipe 30 and the first sewage outlet pipe 40 extend directly from the cover 10 to the bottom of the tank 20. Sewage entering through the sewage inlet 11 flows directly along the first sewage inlet pipe 30 into the bottom of the tank 20. Sewage at the bottom of the tank 20 can also flow directly along the first sewage outlet pipe 40 to the sewage outlet 12, and then be discharged outside the sewage tank 100.

[0050] In other embodiments of the present application, the first sewage inlet pipe 30 may be provided with a first sewage inlet sub-pipe segment 31 and a second sewage inlet sub-pipe segment 32, while the first sewage discharge pipe 40 may not be provided with a sub-pipe. Alternatively, the first sewage inlet pipe 30 may be provided with no sub-pipe segment, while the first sewage discharge pipe 40 may be provided with a first sewage discharge sub-pipe segment 41 and a second sewage discharge sub-pipe segment 42. This application does not limit the specific form.

[0051] See also Figure 4 , Figure 4 This is a structural diagram of another embodiment of the sewage tank 100 provided in this application. Figure 5 1 is a structural diagram of another embodiment of the sewage tank 100 provided in this application.

[0052] In one embodiment of the present application, a storage space 50 is defined at the bottom of the sewage tank 100, and the first sewage inlet pipe 30 is connected to the storage space 50. That is, after sewage flows out of the first sewage inlet pipe 30, it enters the storage space 50 at the bottom of the sewage tank 100. At this point, solid or semi-solid matter in the sewage is deposited in the storage space 50 and does not come into contact with the sidewalls of the sewage tank 100, thereby preventing the solid or semi-solid matter from adhering to the sidewalls of the sewage tank 100.

[0053] Furthermore, in one embodiment of the present application, the first sewage inlet pipe 30 has a sewage inlet outlet 34 at its bottom, and the accommodating space 50 includes a first groove 35 disposed at a position corresponding to the sewage inlet outlet 34 at the bottom of the sewage tank 100 to accommodate solid or semi-solid substances flowing out through the sewage inlet outlet 34. The first sewage inlet pipe 30 is connected to the first groove 35 via the sewage inlet outlet 34. That is, the first groove 35 is disposed below the sewage inlet outlet 34, and sewage flowing out of the sewage inlet outlet 34 enters the first groove 35. During this process, some liquid substances in the sewage enter the bottom of the sewage tank 100, while solid or semi-solid substances accumulate in the first groove 35. This prevents solid or semi-solid substances from adhering to the sidewalls of the sewage tank 100, thereby facilitating the cleaning of the sewage tank 100.

[0054] It is worth noting that, in some cases, the first sewage inlet pipe 30 includes a first sewage inlet sub-pipe section 31 and a second sewage inlet sub-pipe section 32 that are connected. In this case, the sewage inlet outlet 34 is provided at the bottom of the second sewage inlet sub-pipe section 32.

[0055] In other cases, the first sewage inlet pipe 30 is not provided with a sub-pipe, but a pipe directly extends from the cover 10 to the bottom of the box body 20. In this case, the sewage outlet 34 is provided at the bottom of the first sewage inlet pipe 30.

[0056] Furthermore, in one embodiment of the present application, a first sewage suction port 43 is provided at the bottom of the first sewage pipe 40. That is, to enable the sewage in the sewage tank 100 to be automatically discharged through the first sewage pipe 40, the first sewage suction port 43 is provided at the bottom of the first sewage pipe 40, communicating with the accommodation space 50. The accommodation space 50 also includes a second groove 44 provided at the bottom of the sewage tank 100 at a position corresponding to the first sewage suction port 43. The second groove 44 communicates with the first groove 35, and the first sewage pipe 40 communicates with the second groove 44 via the first sewage suction port 43. That is, to enable solid or semi-solid substances in the first groove 35 and liquid substances at the bottom of the sewage tank 100 to more conveniently enter the first sewage pipe 40, thereby achieving automatic sewage discharge, the present application further provides a second groove 44 that communicates with both the first groove 35 and the first sewage pipe 40.

[0057] In one embodiment of the present application, at least one second sewage suction port 45 is provided on a side wall of the first sewage pipe 40 near the bottom, and the second sewage suction port 45 is communicated with the bottom of the sewage tank 100 .

[0058] After the sewage flows out of the sewage inlet and outlet 34 of the first sewage pipe 40, some of the liquid substances in the sewage will enter the bottom of the sewage tank 100, while the solid or semi-solid substances and some of the liquid substances will accumulate in the first groove 35. When the sewage needs to be discharged from the first sewage pipe 40, the liquid, solid or semi-liquid substances in the sewage will enter the second groove 44 through the first groove 35 and finally enter the first sewage pipe 40. During this process, some sewage may be retained at the bottom of the sewage tank 100. This part of the sewage will enter the first sewage pipe 40 through the multiple second sewage suction ports 45 provided on the side wall of the first sewage pipe 40 near the bottom, thereby achieving complete discharge of the sewage and preventing some sewage from being retained at the bottom of the sewage tank 100. The present application does not impose any specific restrictions on the number and shape of the second sewage suction ports 45 , and they can be specifically configured according to actual circumstances. A second sewage suction port 45 can be provided on each side wall of the first sewage pipe 40 , or multiple second sewage suction ports 45 can be provided on both sides of the first sewage pipe 40 , or a second sewage suction port 45 can be provided on only one side wall of one of the first sewage pipes 40 . The second sewage suction port 45 can be an arc-shaped opening at the bottom of the first sewage pipe 40 , or it can be an opening of any shape, such as a circle, rectangle, square, or oval, at the bottom of the first sewage pipe 40 , as long as it facilitates the sewage in the sewage tank 100 to enter the first sewage pipe 40 and then be discharged from the sewage tank 100 .

[0059] See also Figure 6 , Figure 6 1 is a structural diagram of another embodiment of the sewage tank 100 provided in this application.

[0060] In one embodiment of the present application, the first sewage pipe 40 is provided with an arc-shaped opening 46 near the bottom of the sewage tank 100. The arc-shaped opening 46 is connected to the first sewage suction port 43. The arc-shaped opening 46 at the bottom of the first sewage pipe 40 is designed to ensure that the sewage airflow has no dead angles, thereby allowing the sewage to be better sucked into the first sewage pipe 40.

[0061] It is worth noting that, in some cases, the first sewage pipe 40 includes a first sewage sub-pipe section 41 and a second sewage sub-pipe section 42 that are connected. In this case, the arc-shaped opening 46 is provided at the bottom of the second sewage sub-pipe section 42.

[0062] In other cases, the first sewage pipe 40 is not provided with a sub-pipe, but a pipe extends directly from the cover 10 to the bottom of the box body 20. In this case, the arc-shaped opening 46 is provided at the bottom of the first sewage pipe 40.

[0063] See also Figure 7 、 Figure 8 , Figure 7 This is a schematic structural diagram of an embodiment of a cleaning device 200 provided in this application. Figure 8 It is a structural schematic diagram of another embodiment of the cleaning device 200 provided in this application.

[0064] In addition, the present application also provides a cleaning device 200, which includes a body 93, a second sewage inlet pipe 60, and the sewage tank 100 described above. The second sewage inlet pipe 60 is disposed on the body 93, and the sewage tank 100 is detachably disposed on the body 93. The second sewage inlet pipe 60 is disposed outside the sewage tank 100 and communicates with the sewage inlet 11. One end of the second sewage inlet pipe 60 communicates with the outside and the other end communicates with the sewage tank 100. The second sewage inlet pipe 60 is used to draw sewage from the outside and transport it into the sewage tank 100. For example, when the cleaning device 200 is used to clean the floor, the second sewage inlet pipe 60 can draw sewage from the floor and transport it to the sewage inlet 11, thereby entering the interior of the sewage tank 100 through the first sewage inlet pipe 30. As a result, the present application can implement the automatic sewage suction function of the cleaning device 200.

[0065] In addition, the cleaning device 200 of the present application further includes a second drain pipe 70, which is disposed on the body 93 and arranged side by side with the second sewage inlet pipe 60. The second drain pipe 70 is disposed outside the sewage tank 100 and is connected to the sewage outlet 12. As previously mentioned, after the sewage enters the sewage tank 100, if it is necessary to drain the sewage tank 100, the first drain pipe 40 can be used to transfer the sewage stored in the sewage tank 100 to the sewage outlet 12, and further transported to the second drain pipe 70 through the sewage outlet 12, thereby enabling the sewage to be automatically discharged outside the sewage tank 100 without the need to manually dump the sewage in the sewage tank 100, thereby facilitating operation.

[0066] Furthermore, in one embodiment of the present application, to facilitate cleaning or replacement of the sewage tank 100, the second sewage inlet pipe 60 and the second sewage outlet pipe 70 can be configured to be detachably connected to the sewage tank 100. The specific connection method can be a snap connection, a threaded connection, etc., as long as the second sewage inlet pipe 60 and the second sewage outlet pipe 70 can be detachably connected to the sewage tank 100, and this application does not make any specific restrictions here.

[0067] In summary, the cleaning device 200 provided in the present application is provided with a second sewage inlet pipe 60, a second sewage discharge pipe 70, and the sewage tank 100 as described above. The second sewage inlet pipe 60 and the second sewage discharge pipe 70 are provided on the body 93, and the sewage tank 100 is detachably connected to the body 93. The second sewage inlet pipe 60 and the second sewage discharge pipe 70 are both provided outside the sewage tank 100, the second sewage inlet pipe 60 is connected to the sewage inlet port 11, and the second sewage discharge pipe 70 is connected to the sewage discharge port 12. This avoids excessive occupation of the internal space of the sewage tank 100 caused by providing both the second sewage inlet pipe 60 and the second sewage discharge pipe 70 inside the sewage tank 100, thereby saving the internal space of the sewage tank 100 and effectively improving the utilization rate of the sewage tank 100.

[0068] See also Figure 9 , Figure 9 It is a structural schematic diagram of an embodiment of a cleaning system 300 provided in this application.

[0069] like Figure 9 As shown, the present application provides a cleaning system 300, comprising a base station 80 and the cleaning device 200 as described above. The base station 80 is provided with a suction assembly (not shown). When the cleaning device 200 is docked at the base station 80, the suction assembly is connected to the second sewage pipe 70. In other words, when the cleaning device 200 is docked at the base station 80, the second sewage pipe 70 is connected to the base station 80.

[0070] In one embodiment of the present application, the cleaning device 200 of the present application is further provided with components such as a handle 90, a floor brush 91, a clean water tank 92, and the aforementioned sewage tank 100. The handle 90 is used for the user to operate the cleaning device 200 by hand; the floor brush 91 is disposed at the bottom of the cleaning device 200, and the second sewage inlet pipe 60 is connected to the floor brush 91, which is in direct contact with the ground for cleaning; the clean water tank 92 is used to store clean water. When the cleaning device 200 starts the self-cleaning operation, a water pump (not shown) guides the clean water in the clean water tank 92 through the clean water pipe (not shown) to the floor brush 91, so that the floor brush 91 is rinsed with clean water.

[0071] The cleaning system 300 of the present application includes the cleaning device 200 and the base station 80 as described above. The base station 80 is used for the cleaning device 200 to dock and complete operations such as charging, water injection, and sewage discharge. The base station 80 is equipped with a suction component. When the cleaning device 200 is docked at the base station 80, the suction component is connected to the second sewage pipe 70. If sewage discharge is required, the suction component will provide suction force, so that the sewage at the bottom of the box 20 is sucked into the first sewage pipe 40, and then sent to the sewage outlet 12 by the first sewage pipe 40. The sewage then enters the second sewage pipe 70 and is finally sucked into the base station 80, and then stored by the base station 80 or discharged to the outside by the base station 80. In this way, automatic sewage discharge can be achieved, providing convenience for users.
