Figure 5 Figure 5 In recent years, cleaning robots and other cleaning devices have become increasingly popular due to their high degree of intelligence, bringing great convenience to people's lives. After performing the mopping task, the cleaning device can perform self-cleaning of the mop or return to the base station to clean the mop. The sewage after cleaning the mop is mixed with hair, dust, food and other impurities, which can easily cause blockage of the pipeline, valve, etc. To solve this problem, the present disclosure provides a cleaning base station 1001 (as shown), a cleaning device 1002 (as shown), and a cleaning system 1000 (as shown).​Figure 5 (As shown).

[0039] The following detailed description of some embodiments of this disclosure is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other. It should be noted that the cleaning base station 1001 of this disclosure is applicable to any type of cleaning equipment 1002, including but not limited to this disclosure. Figure 5 The cleaning equipment 1002 shown.

[0040] Please see Figure 1 and Figure 5 This disclosure provides a cleaning base station 1001, including a base station body 1003 and a control valve 100, with the control valve 100 disposed within the base station body 1003. The base station body 1003 is a component for housing other components of the cleaning base station 1001 besides itself. The base station body 1003 typically includes a base, a top, and sidewalls, which together form a semi-enclosed structure. An opening in the semi-enclosed structure allows a cleaning device 1002 to enter and exit. The base can be used to collect wastewater discharged from the cleaning device 1002 and liquids generated by the cleaning base station 1001's own liquid supply. For details, please refer to [link to relevant documentation]. Figure 5 The base is provided with a cleaning tank 1005, which can be a groove opened on the base or a groove structure that can be removed from the base, for accommodating and cleaning the cleaning component 1006 of the cleaning equipment 1002 that returns to the cleaning base station 1001.

[0041] Please see Figure 1 , Figure 2 and Figure 3In some embodiments, the control valve 100 comprises a bracket 10 and a valve body 20. The bracket 10 comprises a first space 101, a first channel 102, a first port 103 and a second port 104 which are in communication with the first space 101. The first channel 102 is in communication with the power device 220. For example, the bracket 10 is a hollow cylinder, the hollow part of the cylinder is the first space 101, and the openings at the upper and lower ends of the cylinder are the first port 103 and the second port 104.

[0042] In some embodiments, the valve body 20 is arranged in the first space 101, and a sealed space 201 is formed between the outer wall of the valve body 20 and the inner wall of the bracket 10. The valve body 20 comprises a second channel 202, a first opening 203 and a second opening 204 which are in communication with the second channel 202. For example, the valve body 20 is arranged in the bracket 10. For example, the valve body 20 is a hollow cylinder, the hollow part of the cylinder is the second channel 202, and the openings at the upper and lower ends of the cylinder are the first opening 203 and the second opening 204.

[0043] For example, the liquid can enter the second channel 202 from the first opening 203 and be discharged from the second opening 204. For example, the liquid is sewage containing dirt.

[0044] For example, the sealed space 201 surrounds the outer wall of the valve body 20, or the sealed space 201 is located outside part of the outer wall of the valve body 20.

[0045] For example, part of the outer wall of the valve body 20 abuts the inner wall of the bracket 10, and the other part is spaced from the inner wall of the bracket 10 to form the sealed space 201. That is, the sealed space 201 is part of the first space 101.

[0046] In some embodiments, the diameter of at least part of the valve body 20 between the first opening 203 and the second opening 204 is smaller than the diameter of the first opening 203. In some embodiments, the diameter of at least part of the valve body 20 between the first opening 203 and the second opening 204 is smaller than the diameter of the second opening 204. The part of the valve body 20 with a diameter smaller than the diameter of the first opening 203 or the second opening 204 can be other than the first opening 203 and the second opening 204, can be a small part in the middle of the valve body 20, or can be a part close to the first opening 203 or the second opening 204; the specific arrangement can be determined according to the actual situation.

[0047] For example, the diameter of the first opening 203 can be the same as or different from the diameter of the second opening 204. Specifically, the diameter of the first opening 203 is the same as the diameter of the second opening 204.

[0048] In some embodiments, the at least part of the valve body 20 between the first opening 203 and the second opening 204 can be a middle part of the valve body 20, or can be two end parts of the valve body 20; that is, the part of the valve body 20 with a diameter smaller than that of the first opening 203 or the second opening 204 can be a middle part of the valve body 20, or can be two end parts of the valve body 20, for example, the part of the valve body 20 with a diameter smaller than that of the first opening 203 or the second opening 204 is a middle part of the valve body 20, that is, the distance of the part from the first opening 203 and the second opening 204 is the same; for another example, the part of the valve body 20 with a diameter smaller than that of the first opening 203 or the second opening 204 is two end parts of the valve body 20, that is, the distance of the part from the first opening 203 is greater than that from the second opening 204, or the distance of the part from the first opening 203 is less than that from the second opening 204.

[0049] In some embodiments, the closed space 201 is arranged at least around the outer periphery of the part of the valve body 20 with a diameter smaller than that of the first opening 203 or the second opening 204, or the closed space 201 is arranged at least on the outer periphery of the part of the valve body 10 with a diameter smaller than that of the first opening 203 or the second opening 204 (for example, the closed space 201 is arranged on one side of the part of the valve body 10).

[0050] For example, when the valve body 20 is installed in the bracket 10, at least part of the valve body 20 between the first port 103 and the second port 104 is not in contact with the inner wall of the bracket 10, that is, after the valve body 20 is installed in the bracket 10, the part of the valve body 20 in contact with the first port 103 and the second port 104 needs to be connected therewith, in order to ensure the tight connection of the valve body 20 with the first port 103 and the second port 104, the part of the valve body 20 in contact with the first port 103 and the second port 104 can be deformed to a certain extent, and even can have a certain wrinkle; at least part of the valve body 20 is not in contact with the inner wall of the bracket 10 or does not have deformation in the bracket 10, that is, the valve body 20 does not have a wrinkle or other changes caused by the extrusion of the inner wall of the bracket 10, when the inner surface or inner side of the outer wall of the elastic part of the valve body 20 abuts against each other to close the second channel 202, the influence of the wrinkle on the closing of the second channel 202 is reduced, which is conducive to improving the sealing performance of the elastic part of the valve body 20 when closing the second channel 202, and when the outer wall of the elastic part of the valve body 20 moves away from the center of the valve body 20 to expand the second channel 202, it is conducive to keeping the second channel 202 unobstructed and reducing the occurrence of the wrinkle in the second channel 202, thereby improving the stability of the deformation of the elastic part of the valve body 20 to close, open or expand the second channel 202.

[0051] In some embodiments, at least a portion of the valve body 20 is elastic, and in particular, the diameter of the elastic portion of the valve body 20 is smaller than the diameter of the first opening 203 or the second opening 204. The power device 220 passes fluid into the closed space 201 through the first channel 102 to deform the elastic portion of the valve body 20 to close the second channel 202. The power device 220 stops passing fluid into the closed space 201 to allow the deformed elastic portion of the valve body 20 to restore itself to open the second channel 202, facilitating the discharge of sewage. In some embodiments, the power device 220 extracts fluid in the closed space 201 to deform the elastic portion of the valve body 20 to expand the second channel 202. For example, the shape of the valve body 20 can be the shape of two duckbill valve openings connected together, and the opening and closing of the second channel 202 can be controlled by controlling the opening and closing of the connected part of the two duckbill valve openings. For another example, the shape of the valve body 20 can be the shape of two funnel openings connected together, and the shape of the valve body 20 can be the shape of a funnel with a narrow middle and wide ends.

[0052] By controlling the valve body 20 by the power device 220 to expand the second channel 202, the discharge of sewage is further facilitated, the discharge efficiency is improved, the blockage of the valve body 20 is reduced, and the user experience is improved.

[0053] For example, the power device 220 includes a gas pump, and the fluid includes gas. When the gas pump passes gas into the closed space 201 through the first channel 102, the gas deforms the elastic portion of the valve body 20, i.e., the outer wall of the elastic portion of the valve body 20 moves towards the center of the valve body 20 until the outer wall of the elastic portion of the valve body 20 abuts each other to close the second channel 202, in particular, the inner surface or inner side of the outer wall of the elastic portion of the valve body 20 abuts each other to close the second channel 202; or in other words, the elastic portion of the valve body 20 is deformed by the action of positive pressure to close the second channel 202; when the gas pump stops passing gas into the closed space 201, in the process of the gas in the closed space 201 being gradually released, or in the process of the gas pressure in the closed space 201 gradually reaching equilibrium, when the restoring force of the deformed elastic portion of the valve body 20 is greater than the gas pressure in the closed space 201, the deformed elastic portion of the valve body 20 restores itself to open the second channel 202, i.e., the outer wall of the elastic portion of the valve body 20 moves away from the center of the valve body 20 until the outer wall of the elastic portion of the valve body 20 does not abut each other to open the second channel 202; when the gas pump extracts the gas in the closed space 201, the gas pressure in the closed space 201 is less than the gas pressure in the valve body 20, so that the elastic portion of the valve body 20 is deformed to expand the second channel 202, i.e., the outer wall of the elastic portion of the valve body 20 moves away from the center of the valve body 20 until the outer wall of the elastic portion of the valve body 20 expands to its maximum extent to expand the second channel 202.

[0054] Exemplarily, the power device 220 comprises a liquid pump, and the fluid comprises liquid. For example, the power device 220 is a water pump, and the fluid is water. When the liquid pump supplies liquid to the sealed space 201 through the first channel 102, the liquid deforms the elastic part of the valve body 20, i.e., the outer wall of the elastic part of the valve body 20 moves towards the center of the valve body 20 until the outer wall of the elastic part of the valve body 20 abuts against each other to close the second channel 202, in particular, the inner surface or inner side of the outer wall of the elastic part of the valve body 20 abut against each other to close the second channel 202; or in other words, the elastic part of the valve body 20 is deformed by the positive pressure to close the second channel 202. When the liquid pump stops supplying liquid to the sealed space 201, the liquid in the sealed space 201 is gradually released, or in other words, the liquid pressure in the sealed space 201 gradually reaches equilibrium. When the restoring force of the deformed elastic part of the valve body 20 is greater than the liquid pressure in the sealed space 201, the deformed elastic part of the valve body 20 restores to its original state to open the second channel 202, i.e., the outer wall of the elastic part of the valve body 20 moves away from the center of the valve body 20 until the outer wall of the elastic part of the valve body 20 does not abut against each other to open the second channel 202. When the liquid pump pumps out the liquid in the sealed space 201, the liquid in the sealed space 201 is pumped out and continues to be pumped out, and the air pressure in the sealed space 201 is less than the air pressure in the valve body 20, so that the elastic part of the valve body 20 is deformed to expand the second channel 202, i.e., the outer wall of the elastic part of the valve body 20 moves away from the center of the valve body 20 until the outer wall of the elastic part of the valve body 20 expands to its maximum extent to expand the second channel 202.
