[0039] like Figures 1 to 7As shown, according to the implementation mode of the utility model, the first aspect of the utility model proposes a cleaning base station 101, the cleaning base station 101 includes a base station body 10, a sewage pipe 11 and a negative pressure device 12, the base station body 10 is used to detachably place the cleaning equipment 102, the sewage pipe 11 is arranged on the base station body 10, the sewage pipe 11 has an inlet and an outlet, when the cleaning equipment 102 is placed on the base station body 10, the inlet of the sewage pipe 11 is connected with the sewage tank 20, the negative pressure device 12 is installed on the base station body 10 and is connected with the outlet of the sewage pipe 11, the negative pressure device 12 is used to generate negative pressure to draw the sewage in the sewage tank 20 into the sewage pipe 11.

[0040] It can be understood that the cleaning base station 101 can be a cleaning base station 101 that is matched with a surface cleaning device 102 such as a floor scrubber, a washing and mopping robot, or a sweeper. The cleaning base station 101 is used to place the cleaning device 102. The cleaning device 102 includes a cleaning part 26 and a sewage tank 20. The cleaning part 26 is used to perform friction cleaning on the surface to be cleaned. The sewage tank 20 is used to receive sewage after cleaning the cleaning part 26. The cleaning base station 101 can provide a placement location for the above-mentioned cleaning device 102 and charge it. The cleaning base station 101 is usually placed on the ground. The cleaning base station 101 has a shell. The sewage pipe 11 can be an independent pipe structure, or the shell of the cleaning base station 101 can define the pipe through an integrated structure. The sewage pipe 11 has an inlet and an outlet. When the cleaning device 102 is placed on the base station body 10, the inlet of the sewage pipe 11 is connected to the outlet on the cleaning device 102, so that the sewage pipe 11 is connected to the sewage tank 20, and the outlet of the sewage pipe 11 can be connected to the negative pressure device 12. The negative pressure device 12 can be a centrifugal pump. A mounting structure can be set on one side of the base station body 10 to fix the negative pressure device 12. For example, a mounting seat or mounting cavity that matches the shape of the negative pressure device 12 is integrally formed through the shell of the base station body 10, and the negative pressure device 12 is fixed to the mounting structure by clamping or bolting. The inlet of the negative pressure device 12 is connected to the outlet of the sewage pipe 11, and the outlet of the negative pressure device 12 can be connected to the outside of the cleaning base station 101, for example, plugged into the floor drain through a pipeline. At this time, after the negative pressure device 12 is started, the sewage in the sewage tank 20 can be discharged into the floor drain along the sewage pipe 11, making the cleaning of the sewage tank 20 more convenient, reducing the cleaning time and difficulty of the user.

[0041] The utility model arranges a sewage discharge pipe 11 on the base station body 10. When the cleaning component is placed on the base station body 10, the sewage tank 20 of the cleaning component is connected with the sewage discharge pipe 11, and the negative pressure device 12 is started to generate negative pressure, so that the sewage in the sewage tank 20 is driven by the negative pressure to flow along the sewage discharge pipe 11 to the negative pressure device 12, and finally discharged to the outside of the base station body 10, so that the sewage tank 20 is cleaned, saving the user's time and energy.

[0042] It is understandable that if Figures 1 to 3 As shown, in some embodiments of the present invention, the negative pressure device 12 includes a centrifugal pump, which is installed on the base station body 10, the inlet end of the centrifugal pump is connected to the outlet end of the sewage pipe 11, and the outlet end 121 of the centrifugal pump is used to connect to the outside of the cleaning base station 101.

[0043] It is understandable that the negative pressure device 12 can adopt a more mature centrifugal pump. The centrifugal pump generates negative pressure through the rotation of its own impeller to pump the gas and sewage in the sewage pipe 11 and the sewage tank 20, and discharge them into the floor drain, so as to achieve convenient cleaning of the sewage tank 20 and improve the user experience. More specifically, the centrifugal pump can be placed vertically and conveniently installed in the seat formed by the outer shell of the base station body 10. The inlet end of the centrifugal pump can be connected and fixed to the outlet end of the sewage pipe 11 through a snap-on structure. In addition, a filter element can also be set on the sewage pipe 11. The filter element has multiple filter holes. The larger waste in the sewage pipe 11 is intercepted by the filter element to reduce the phenomenon of the centrifugal pump being stuck by large particles. The structure of the filter element can refer to the existing pre-pump filter structure.

[0044] like Figures 1 to 5 As shown, the second aspect of the utility model proposes a cleaning system 100, including the cleaning base station 101 and the cleaning equipment 102 proposed in the first aspect of the utility model, the cleaning equipment 102 is placed on the cleaning base station, the cleaning equipment 102 includes an equipment body, a cleaning component 26 and a sewage tank 20, the cleaning component 26 is rotatably arranged on the equipment body, the sewage tank 20 is installed on the equipment body, and is used to hold sewage after cleaning the cleaning component 26.

[0045] The cleaning system 100 proposed in the second aspect of the utility model has the same beneficial effects as the cleaning base station 101 proposed in the first aspect of the utility model. The cleaning device 102 can be a surface cleaning device 102 such as a floor scrubber, a vacuum cleaner, or a washing and mopping robot. The cleaning base station 101 proposed in the first aspect of the utility model can be placed on the ground to provide a fixing and charging function when the cleaning device 102 is idle. The cleaning base station 101 can be set close to the floor drain for the convenience of sewage discharge, and can be connected to the floor drain through a pipeline or a sewage outlet can be opened on the cleaning base station 101 to directly align with the floor drain for sewage discharge and block the floor drain. A placement surface 13 can be set on the upper side of the cleaning base station 101 for supporting the cleaning device 102, and a connecting structure is set to fix the cleaning device 102.

[0046] like Figures 3 to 5As shown, in some embodiments of the utility model, the cleaning device also includes a self-cleaning subsystem, which is arranged on the device body. The device body includes a floor brush assembly 104 and a body assembly 105. The cleaning member 26 is rotatably arranged on the floor brush assembly 104. The sewage tank 20 is arranged in the body assembly 105. The self-cleaning subsystem is used to clean the cleaning member 26 and suck the cleaned sewage. In the suction direction of the self-cleaning subsystem, the sewage tank 20 is arranged downstream of the cleaning member 26.

[0047] It can be understood that the floor brush assembly 104 is arranged at the bottom end of the body assembly 105, and is the part of the floor scrubber that performs cleaning work on the surface to be cleaned. The floor brush assembly 104 includes a shell and a driving mechanism. The front end of the shell is provided with a storage space for placing the cleaning member 26. The driving device can select a motor, and is connected to the cleaning member 26 through the transmission mechanism, thereby driving the cleaning member 26 to rotate, so as to frictionally clean the surface to be cleaned. The self-cleaning subsystem may include a spray component, a scraper 27, a first sewage extraction channel 22, a second sewage extraction channel 23 and a fan 106. The spray component sprays and wets the cleaning component 26 by spraying clean water or cleaning liquid. The scraper 27 abuts against the cleaning surface of the cleaning component 26, and scrapes the cleaning surface of the cleaning component 26 when the cleaning component 26 rotates. The inlet of the first sewage extraction channel 22 is arranged near the cleaning component 26. The operation of the fan 106 can create negative pressure in the sewage tank 20. The second sewage extraction channel 23 and the first sewage extraction channel 22 connected to the sewage tank 20 create negative pressure near the scraper 27 to suck the scraped sewage and collect the sewage into the sewage tank 20. The cleaning element 26 is cleaned by the self-cleaning subsystem, which reduces the time for the user to manually clean the cleaning element 26 and improves the user experience. The sewage tank 20 collects the sewage after the cleaning element is cleaned. In conjunction with the cleaning base station 101 proposed in the utility model, the sewage after the cleaning element is cleaned can be automatically collected and discharged, further reducing the workload of the user after using the floor scrubber for cleaning, thereby improving the user experience.

[0048] like Figure 2 and Figure 5As shown, in some embodiments of the present invention, the self-cleaning subsystem includes a scraper 27, a first sewage extraction channel 22, a second sewage extraction channel 23 and a fan 106. The scraper 27 is arranged on the floor brush assembly 104 and is used to scrape the surface of the cleaning member 26. The first sewage extraction channel 22 is arranged in the floor brush assembly 104, and the inlet 221 of the first sewage extraction channel is arranged close to the cleaning member 26. The second sewage extraction channel 23 is arranged in the body assembly 105, and the inlet of the second sewage extraction channel 23 is connected to the outlet of the first sewage extraction channel 22. The outlet 231 is connected to the sewage tank 20, the fan 106 is arranged in the fuselage assembly 105, for example, above the sewage tank 20, the top opening of the sewage tank 20 is connected to the air suction port of the fan 106, and the second sewage suction channel 23 and the third sewage suction channel 24 are both connected to the sewage tank 20 through the top opening of the sewage tank 20, the air suction port of the fan 106 is connected to the sewage tank 20, and the fan 106 is used to create negative pressure in the sewage tank 20 to suck the sewage scraped by the scraping member 27 into the sewage tank 20 along the first sewage suction channel 22 and the second sewage suction channel 23.

[0049] It can be understood that the body assembly 105 includes a frame and a shell covering the frame. The body assembly 105 is in a long cylindrical structure. A receiving groove 21 is provided on one side of the body assembly 105 along its own radial direction, that is, on the front side of the body assembly 105. The shape of the receiving groove 21 is adapted to the sewage tank 20, for example, a capsule type. The opening of the receiving groove 21 faces the radial outer side of the body assembly 105, so that the sewage tank 20 can be installed in the receiving groove 21 in a detachable manner, saving the volume of the body and facilitating disassembly and maintenance. The second sewage extraction channel 23 and the third sewage extraction channel 24 may be of a straight tube structure and extend along the length direction of the fuselage assembly 105 and are arranged in the accommodating groove 21. The second sewage extraction channel 23 and the third sewage extraction channel 24 may be exposed by removing the sewage tank 20, so that the second sewage extraction channel 23 and the third sewage extraction channel 24 are convenient for installation, disassembly and maintenance. A guide member 28 may be arranged between the second sewage extraction channel 23 and the third sewage extraction channel 24 and the sewage tank 20, that is, the guide member 28 is arranged at the top opening of the sewage tank 20, and the guide member 28 has a first guide channel and a second guide channel. The second sewage extraction channel 23 is connected with the sewage tank 20 through the first guide channel, and the third sewage extraction channel 24 is connected with the sewage tank 20 through the second guide channel. The flow direction of the sewage extraction channel is guided into the sewage tank 20 by arranging the guide member 28. Specifically, one end of the second sewage extraction channel 23 away from the floor brush assembly 104, that is, the outlet 231 of the second sewage extraction channel is communicated with the sewage tank 20, and one end of the second sewage extraction channel 23 close to the floor brush assembly 104 is communicated with the outlet of the first sewage extraction channel 22 arranged in the floor brush assembly 104. One end of the third sewage extraction channel 24 away from the floor brush assembly 104, that is, the inlet 241 of the third sewage extraction channel is communicated with the sewage tank 20, and when the cleaning device 102 is placed on the base station body 10, one end of the third sewage extraction channel 24 close to the floor brush assembly 104, that is, the outlet 242 of the third sewage extraction channel is communicated with the inlet of the sewage discharge pipeline 11.

[0050] like Figures 2 to 4 As shown, in some embodiments of the present invention, the cleaning equipment 102 also includes a pipeline on-off control mechanism 25, which is connected in series between the third sewage extraction channel 24 and the sewage discharge pipeline 11. The pipeline on-off control mechanism 25 is configured to open the third sewage extraction channel 24 when the negative pressure device 12 of the cleaning base station 101 is started, and to close the third sewage extraction channel 24 when the fan 106 is started.

[0051] It can be understood that the pipeline on-off mechanism can be a valve or an air valve, and the basic structure of the air valve can refer to the existing structure. The valve or air valve can block the outlet 242 of the third sewage pumping channel under the negative pressure generated by the fan, so as to achieve the closure of the third sewage pumping channel 24 to reduce sewage leakage, and open the outlet 242 of the third sewage pumping channel under the negative pressure of the centrifugal pump, so as to achieve the third sewage pumping channel 24 is connected to the sewage pipe 11, so that the negative pressure of the centrifugal pump can continue to act on the sewage tank 20 to suck the sewage in the sewage tank 20. It can also be an electrically controlled on-off mechanism, such as a mechanism in which a motor and a transmission mechanism drive a valve plate to control the on-off of the pipeline.

[0052] Figures 2 to 4 As shown, in some embodiments of the utility model, the pipeline on-off control mechanism includes a valve assembly, the valve assembly includes a valve flap 251, the valve flap 251 is rotatably arranged at the outlet 242 of the third sewage extraction channel, the valve flap 251 can be flipped to open the outlet 242 of the third sewage extraction channel when the negative pressure device 12 of the cleaning base station is started, and can be engaged with the outlet 242 of the third sewage extraction channel to close the third sewage extraction channel 24 when the fan 106 is started.

[0053] It can be understood that, taking the pipeline on-off mechanism including the valve assembly as an example, the valve flap 251 has a hinged portion 252, and the hinged portion 252 is hingedly connected to the pipe wall of the outlet 242 of the third sewage extraction channel. When the cleaning device 102 performs a cleaning operation, the fan 106 inside the cleaning device 102 runs to generate negative pressure, and the valve flap 251 flips under the action of the negative pressure, and then adsorbs on the outlet 242 of the third sewage extraction channel, so that the third sewage extraction channel 24 is closed. When placed on the cleaning base station 101, the centrifugal pump on the cleaning base station 101 side starts to work and generates negative pressure, and the valve flap 251 flips under the action of the negative pressure, and then the outlet 242 of the third sewage pumping channel is opened, so that the negative pressure of the centrifugal pump can continue to act on the sewage tank 20 along the third sewage pumping channel 24, so as to pump the sewage in the sewage tank 20 and discharge it outside the cleaning base station 101 along the third sewage pumping channel 24, the valve flap 251, the sewage pipe 11, and the centrifugal pump, such as into a floor drain. By setting a pipeline on-off mechanism to control the on-off of the third sewage pumping channel, the overall air tightness is enhanced, and the phenomenon of accidental leakage of sewage in the sewage tank 20 is reduced.

[0054] like Figure 2 As shown, in some embodiments of the utility model, the cleaning base station 101 also includes a connecting seat 14 and a placement surface 13, and the connecting seat 14 and the placement surface 13 are arranged on the same side of the base station body 10, and the connecting seat 14 has a connecting structure for cooperating with the fuselage assembly 105, and the placement surface 13 is used to place and support the floor brush assembly 104, and one side of the placement surface 13 is partially recessed to form a placement groove 15 for accommodating the cleaning member 26.

[0055] It is understandable that a connection seat 14 and a placement surface 13 can be provided on one side of the base station body 10, that is, the top side of the base station body 10. The placement surface 13 can be matched with the bottom side of the floor brush assembly 104. The connection seat 14 protrudes from the top side of the base station body 10. The connection seat 14 can be provided with a slot or a buckle or other connection structure that matches the fuselage assembly 105. The connection seat 14 is provided near the rear side of the base station body 10. The placement surface 13 is partially recessed near the front side of the base station body 10 to form a placement groove 15. The placement groove 15 is adapted to the shape of the cleaning part and is used to accommodate the cleaning part. In addition, a charging contact or other structure for charging the cleaning device 102 can also be provided on the base station body 10.

[0056] like Figures 1 to 3 As shown, in some embodiments of the present invention, the cleaning member 26 includes a roller brush, which is connected to the device body in a manner that it can rotate along its own axis.

[0057] It can be understood that the roller brush is driven by a motor disposed in the floor brush assembly 104 and rotates along its own axis to clean the surface to be cleaned. The roller brush and its driving structure can refer to the roller brush structure of an existing floor scrubber.

[0058] like Figure 2 As shown, in some embodiments of the utility model, the device body also includes a body assembly 105 and a handle 103, the sewage tank 20 is installed on the body assembly 105, the floor brush assembly 104 is connected to one end of the body assembly 105, and the handle 103 is connected to the end of the body assembly 105 away from the floor brush assembly 104.

[0059] It can be understood that the body assembly 105 is in a long columnar structure, and a handle 103 is provided at one end of the body assembly 105 along its length direction. The structure of the handle 103 can refer to the existing floor scrubber handle 103, that is, the handle 103 is in a long rod shape, and a handle is provided at one end away from the body assembly 105. The handle 103 can be convenient for users to hold and use. The other end of the body assembly 105, that is, the bottom end of the body assembly 105 is installed with a floor brush assembly 104, and the installation method can be a detachable clamping form to facilitate disassembly, maintenance or storage.
