Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs and any method and material similar or equivalent in function to those described herein can be used in the practice of the present application.

[0051] It should be noted that the terms such as "upper", "lower", "left", "right", "intermediate", and "one" and the like as used herein are only for the convenience of description and are not intended to limit the scope of the present application, and the change or adjustment of the relative relationship thereof without substantial change in the technical content is also regarded as the scope of the present application.

[0052] Referring to Figures 1 to 27 The present application provides a cleaning system, which can include a cleaning base station and a host machine, such as a sweeping and mopping robot, and the cleaning base station can be used to implement one or more of the functions of charging, cleaning component washing, garbage recycling, and the like of the sweeping and mopping robot.

[0053] Referring to Figures 1 to 3 The cleaning base station includes a base station body 100 and a sewage cavity 121, a clean water cavity 110, a clean water pump (not shown), a negative pressure device 140, a liquid delivery pipeline 170, a sewage pipeline 160, and a control valve 130 arranged on the base station body 100.

[0054] The shape of the base station body 100 is not limited, for example, it can be a substantially cuboid shape as a whole, or a cuboid shape at the lower part and a spherical shape at the top, but is not limited thereto, and is preferably aesthetically pleasing and small in size in consideration of the need for indoor furnishings.

[0055] The shape and structure of the sewage cavity 121 are not limited, for example, the sewage cavity 121 can be directly arranged on the base station body 100, or a detachable sewage tank 120 can be arranged on the base station body 100, and the sewage cavity 121 is a containing space formed in the sewage tank 120. The structure and wall thickness of the sewage cavity 121 are suitable for manufacturing, and have sufficient strength to be suitable for not deforming when the negative pressure is extracted to a set threshold. One end of the sewage pipeline 160 is communicated to above the highest liquid level of the sewage cavity 121, the other end of the sewage pipeline 160 is communicated to the liquid to be pumped, and the diameter of the sewage pipeline 160 can refer to the diameter of the sewage pipeline 160 on the existing base station. In some embodiments, the minimum inner diameter of the sewage pipeline 160 is greater than 18 mm and less than 25 mm.

[0056] The negative pressure device 140 can perform air extraction on the sewage cavity 121 to reduce the air pressure in the sewage cavity 121, and based on the pressure difference, the sewage enters the sewage cavity 121 through the sewage pipeline 160. The negative pressure device 140 can be any suitable device capable of pumping air, such as a vacuum pump, a centrifugal blower, an axial flow blower, a plunger pump, etc., but is not limited thereto. The communication mode between the air extraction port of the negative pressure device 140 and the sewage cavity 121 is not limited, for example, a hole can be formed in the wall above the highest liquid level of the sewage cavity 121 to form an air extraction hole, the air extraction port of the negative pressure device 140 is directly connected with the air extraction hole, or the air extraction port of the negative pressure device 140 is indirectly communicated with the air extraction hole through a pipeline. Specifically, in the present embodiment, the air extraction port of the negative pressure device 140 is communicated with the sewage cavity 121 through an air extraction pipeline 103, one end of the air extraction pipeline 103 is connected to the air extraction port of the negative pressure device 140, and the other end of the air extraction pipeline 103 is connected to the wall of the chamber above the highest liquid level of the sewage cavity 121.

[0057] The base station body 100 can include a containing cavity arranged at the bottom of the base station body 100 and having an opening for the host to enter, and the containing cavity can further be provided with a charging terminal capable of being electrically connected with the charging device to charge the host. However, it should be noted that if charging is not considered, the charging terminal can not be arranged on the base station body 100 of the present application.

[0058] In some embodiments, the cleaning base station can further include a cleaning tank 180 for performing cleaning operation on the cleaning assembly of the host, and the cleaning tank 180 is formed in the containing cavity. One end of the sewage pipeline 160 is communicated to above the highest liquid level of the sewage cavity 121, and the other end of the sewage pipeline 160 is communicated to the cleaning tank 180. A horn-shaped suction port can be arranged in the cleaning tank 180, and the suction port is at the lowest part of the cleaning tank 180, and the other end of the sewage pipeline 160 can be communicated with the suction port.

[0059] It should be noted that in other embodiments, the cleaning tank 180 can not be provided. For example, a sewage box can be provided on the host, and the cleaning assembly can be cleaned during the cleaning of the host. The sewage collected after cleaning is stored in the sewage box. When the host is docked with the base station, the sewage box can be docked with the sewage pipeline 160, and the sewage pipeline 160 can draw the sewage in the sewage box on the host. For example, when the host enters the cleaning base station and completes positioning, one end of the sewage pipeline 160 is communicated to the top of the sewage cavity 121, and the other end of the sewage pipeline 160 is communicated to the bottom of the sewage box on the host, so as to realize the sewage drawing work of the host.

[0060] In some embodiments, the base station body 100 can further be provided with an on-off assembly 150. The on-off assembly 150 is provided on the sewage pipeline 160, and the on-off assembly 150 has a blocking state of blocking the sewage pipeline 160 and a conduction state of making the sewage pipeline 160 conductive. The on-off assembly 150 can be a pneumatic valve or a hydraulic valve. For example, the pneumatic valve has a gas cavity and a flexible extrusion part, and the gas cavity is located outside the flexible extrusion part. After the gas in the gas cavity increases, the gas promotes the flexible extrusion part to extrude the water passage of the sewage pipeline 160 to block the water passage. After the gas in the gas cavity decreases, the flexible extrusion part restores deformation away from the sewage pipe, and the sewage pipeline 160 is conductive. For example, the sewage pipeline 160 is flexible, and the flexible extrusion part can be arranged outside the sewage pipeline 160. After the gas in the gas cavity increases, the flexible extrusion part protrudes to the side of the sewage pipeline 160, extruding the water passage of the sewage pipeline 160 to block the water passage. After the gas in the gas cavity decreases, the flexible extrusion part restores deformation away from the sewage pipe, and the sewage pipeline 160 is conductive. Alternatively, the sewage pipeline 160 has two segments, and the pneumatic valve is arranged between the two segments. After the gas in the gas cavity increases, the gas promotes the flexible extrusion part to protrude inward, extruding the water passage of the sewage pipeline 160 to block the water passage. After the gas in the gas cavity decreases, the flexible extrusion part restores deformation, and the sewage pipeline 160 is conductive.

[0061] When the on-off assembly 150 is in the blocking state, the sewage cavity 121 can be subjected to a gas extraction operation, so that when the on-off assembly 150 switches to the conduction state, the sewage pipeline 160 can be subjected to a sewage extraction operation by the negative pressure in the sewage cavity 121.

[0062] For example, when the on-off assembly 150 is switched to the blocking state, the negative pressure device 140 can perform the air extraction operation on the sewage cavity 121, so that the negative pressure in the sewage cavity 121 reaches a set threshold value. When the negative pressure in the sewage cavity 121 is maintained at the set threshold value, the on-off assembly 150 is switched to the conducting state, and the sewage in the cleaning tank 180 is sucked into the sewage cavity 121 under the action of the negative pressure in the sewage cavity 121. It should be noted that the set threshold value can be obtained by comprehensively calculating the volume of the liquid to be sucked and the diameter of the sewage pipeline 160 and the suction distance, or can be obtained by experiment. For example, the negative pressure threshold value in the sewage cavity 121 can be set to suck all the sewage in the cleaning tank 180 into the sewage cavity 121 at one time. Considering the diameter of the sewage pipeline 160 of the existing cleaning base station, the distance from the sewage cavity 121 to the cleaning tank 180, and the volume of the cleaning tank 180, the set threshold value can be 30 Kpa. In addition, it should be noted that considering the existence of errors, slight fluctuations above and below the set threshold value are also "maintained", and the slight fluctuations refer to ±10 Kpa.

[0063] By setting the on-off assembly 150 corresponding to the sewage pipeline 160, the sewage pipeline 160 can be cut off, so that a closed space is formed inside the sewage cavity 121. Thus, a larger negative pressure can be formed in the sewage cavity 121 under the action of the negative pressure device 140, which effectively improves the sewage suction speed and reduces the time required for sewage suction. At the same time, the mixing of gas and sewage can be reduced, thereby reducing the bubble sound. In addition, compared with the suction operation mode of extracting air and sucking sewage at the same time, a greater suction force can be obtained, which can increase the carrying rate of the impurities deposited in the cleaning tank 180, reduce the deposition of dirt at the bottom of the cleaning tank 180, and be more conducive to realizing the maintenance-free of the cleaning tank 180.

[0064] The shape and structure of the clean water cavity 110 are not limited, and can refer to the existing structure. The clean water cavity 110 is used to store clean water, provides clean water supply for the cleaning of the ground by the host, and / or provides clean water supply for the cleaning of the cleaning assembly of the host. The host water supply pipeline 171 and the cleaning pipeline 172 can be arranged in the base station body 100. The host water supply pipeline 171 can communicate the clean water cavity 110 and the clean water box of the host, and the cleaning pipeline 172 can communicate the clean water cavity 110 and the cleaning tank 180. For example, the base station body 100 is provided with a host water supply port (not shown) for supplying water to the host and a cleaning water jet port (not shown) for providing clean water during the cleaning of the cleaning assembly of the host. The host water supply pipeline 171 communicates the clean water cavity 110 and the host water supply port, and the cleaning pipeline 172 communicates the clean water cavity 110 and the cleaning water jet port. The sewage formed after the cleaning of the cleaning assembly can enter the sewage pipeline 160 through the sewage suction port of the cleaning tank 180, and then enter the sewage cavity 121.

[0065] The infusion pipeline 170 can be the host water supply pipeline 171, or the cleaning pipeline 172, or the infusion pipeline 170 can include the host water supply pipeline 171 and the cleaning pipeline 172.

[0066] The control valve 130 is installed on the base station body 100, and the installation manner is not limited. In some embodiments, the control valve 130 is detachably connected to the base station body 100, facilitating maintenance.

[0067] When the sewage pipeline 160, the host water supply pipeline 171, the cleaning pipeline 172, the sewage chamber 121, the clean water chamber 110 are arranged on the base station body 100, and the on-off assembly 150 is arranged on the sewage pipeline 160, the control valve 130 can include a first valve segment 130a and a second valve segment 130b. The first valve segment 130a includes a first valve core 133a, and the second valve segment 130b includes a second valve core 133b. The first valve core 133a switches the communication between the clean water chamber 110 and any one of the host water supply pipeline 171 and the cleaning pipeline 172 when moving. The second valve core 133b switches any one of the blocking state and the conducting state of the on-off assembly 150 when moving. The first valve core 133a and the second valve core 133b move synchronously. The switching of the cleaning water circuit and the opening and closing of the sewage pipeline 160 can be realized by controlling the synchronous movement of the two valve cores, which can further simplify the driving structure and / or control structure of the control valve 130, improve the integration of the valves in the base station, and save the space of the base station. For example, the position detection of the movement of the two valve cores and the driving can be realized by sharing a set of position detection elements 13131 and / or a set of driving devices 134.

[0068] When two sets of driving devices 134 are used to control the movement of the first valve core 133a and the second valve core 133b, the same magnetic member can be connected to the first valve core 133a and the second valve core 133b, and a Hall sensor can be used to detect the magnetic member. Since the first valve core 133a and the second valve core 133b move synchronously, the angles of rotation or the lengths of movement of the first valve core 133a and the second valve core 133b are the same, so that the signals detected by the Hall sensor are the same. That is, the signal can be used to realize the switching of the cleaning water circuit and the opening and closing of the sewage pipeline 160 at the same time. For example, when the movement of the first valve core 133a and the second valve core 133b is rotation, the parameter of the rotation angle of the two valve cores can be detected by the above-mentioned set of detection elements 13131, so as to realize the synchronous detection of the switching of the cleaning water circuit and the opening and closing of the sewage pipeline 160, thereby reducing the number of detection elements 13131 and saving the space of the base station.

[0069] The same set of driving devices 134 can be used to control the synchronous movement of the first valve core 133a and the second valve core 133b, thereby reducing the set of driving devices 134 and saving space in the base station. In this embodiment, the same set of detection elements 13131 can be used to detect the movement positions of the first valve core 133a and the second valve core 133b, or two sets of detection elements 13131 can be used to detect the movement positions of the first valve core 133a and the second valve core 133b.

[0070] The first valve core 133a and the second valve core 133b can be connected to form an integrated valve core 133. The connection of the first valve core 133a and the second valve core 133b can facilitate the synchronous movement of the two valve cores, and the integration of the two valve cores is higher. The first valve core 133a and the second valve core 133b can be connected by a detachable manner or a fixed manner. The first valve core 133a and the second valve core 133b can also be integrally formed. The design of integrally forming the two valve cores that need to be separately machined and assembled into one body reduces the number of parts and assembly steps. At the same time, the integrally formed first valve core 133a and second valve core 133b are easier to control the synchronous movement of the two valve cores, and there is no movement deviation, which ensures the control accuracy.

[0071] The control valve 130 can also include a housing. The structure and shape of the housing are not limited. Specifically, according to the classification of the corresponding valve core, the housing includes a first housing 131a corresponding to the first valve core 133a and a second housing 131b corresponding to the second valve core 133b. The first housing 131a and the second housing 131b can be detachably connected or fixedly connected, or integrally formed. The first housing 131a and the second housing 131b can be a single-layer shell structure or a multi-layer shell structure. The movement mode of the first valve core 133a in the first housing 131a and the movement mode of the second valve core 133b in the second housing 131b can be rotation or linear movement.

[0072] In some embodiments, the first valve core 133a is installed in the first housing 131a, and the second valve core 133b is rotatably installed in the second housing 131b and rotates synchronously with the first valve core 133a. During the rotation of the first valve core 133a relative to the first housing 131a, the first valve segment 130a switches the communication between the clean water chamber 110 and any one of the main machine water supply pipeline 171 and the cleaning pipeline 172. During the rotation of the second valve core 133b relative to the second housing 131b, the second valve segment 130b switches the state of the sewage pipeline 160 between the blocked state and the conductive state. The switching of the communication state by rotation has relatively small fluid resistance compared to the switching of the state by linear movement, and has high responsiveness and accuracy. At the same time, the space in the base station is limited, and the rotation of the control valve 130 core can also avoid occupying additional space, thereby increasing the integration of the base station.

[0073] In the cleaning base station, the first valve section 130a includes a first housing 131a and a first valve core 133a installed in the first housing 131a. The first valve core 133a is provided with a first channel 1331. The first housing 131a is provided with a liquid inlet 1301, a first liquid outlet 1304 communicating with the host water supplement pipeline 171, and a second liquid outlet 1302 communicating with the cleaning pipeline 172. When the first channel 1331 communicates with the liquid inlet 1301 and the first liquid outlet 1304, the clean water cavity 110 communicates with the host water supplement pipeline 171. When the first channel 1331 communicates with the liquid inlet 1301 and the second liquid outlet 1302, the clean water cavity 110 communicates with the cleaning pipeline 172. The liquid inlet 1301 communicates with the clean water cavity 110. For example, a clean water pump can be installed on the base station body 100, and the clean water pump is located on the communication pipeline between the clean water cavity 110 and the liquid inlet 1301, and provides power for the cleaning water entering the liquid inlet 1301.

[0074] The liquid flow ports (such as the liquid inlet 1301, the first liquid outlet 1304, and the second liquid outlet 1302) are provided on the housing, and the channels are provided on the corresponding valve cores. By switching the communication between the channels and different liquid flow ports, the switching of the host water supplement pipeline 171 and the cleaning pipeline 172 can be realized, and the structure is more simple and compact. Further, on the basis of this structure, the control valve 130 core is rotated relative to the housing to realize the communication between the channels and different liquid flow ports, which can also reduce the simplicity of the structure settings such as driving and position detection.

[0075] In the cleaning base station, the on-off assembly 150 can be a pneumatic valve, and the base station body 100 is provided with an air inlet channel and an air outlet pipeline 101. When the pneumatic valve communicates with the air inlet channel, the gas enters the air cavity through the air inlet channel. When the pneumatic valve communicates with the air outlet pipeline 101, the gas flows out of the air cavity through the air outlet pipeline 101. The second valve section 130b switches the pneumatic valve to communicate with any one of the air inlet channel and the air outlet pipeline 101. By switching the communication state of the pneumatic valve with the air inlet channel or the air outlet pipeline 101, the gas enters or exits the pneumatic valve. The pneumatic valve has high sealing performance and reliability, and using the pneumatic valve as the on-off assembly 150 can improve the sealing performance and reliability of the sewage pipeline blocking and conducting.

[0076] In some embodiments, the negative pressure device 140 is in communication with the air inlet channel, and the negative pressure device 140 extracts the gas in the sewage cavity 121 and delivers it to the air inlet pipe to make the gas enter the air cavity. In this way, only one negative pressure device 140 and one pneumatic valve are needed to perform the air extraction operation on the sewage cavity 121 and to achieve the blocking and conduction of the sewage pipe, thereby further saving the internal space of the base station. In addition, by driving the pneumatic valve with the gas extracted from the sewage cavity 121, the sewage cavity 121 can be simultaneously subjected to negative pressure when the sewage pipe is blocked, thereby saving the time for continuing to extract negative pressure from the sewage cavity 121 after the sewage pipe is blocked. In addition, the pneumatic valve requires less gas, and the negative pressure extracted from the sewage cavity 121 at the beginning will not cause sewage to enter the sewage pipe or only a small amount of sewage to enter the sewage pipe, which will not have a great impact on the blocking of the sewage pipe.

[0077] Of course, in the present application, the air inlet channel can also be in communication with another air pump arranged separately, as long as the gas can enter the air cavity to achieve the switching of the sewage pipeline 160 between the blocking state and the conduction state.

[0078] In an embodiment of the cleaning base station, the air outlet pipe 101 is in communication with the atmosphere to make the gas in the air cavity discharged into the atmosphere, and the gas of the pneumatic valve is directly discharged into the atmosphere without the need for an additional pipe, thereby further saving the internal space of the base station. Of course, in the present application, the gas of the pneumatic valve can also be returned to the sewage cavity 121 through a separately arranged pipe. In the case where the gas of the pneumatic valve comes from the sewage cavity 121, the gas is discharged into the atmosphere, which will cause the gas with an odor to enter the atmosphere, affecting the user experience.

[0079] In an embodiment of the cleaning base station, the second valve section 130b includes a second housing 131b, and the second valve core 133b is installed in the second housing 131b. The second valve core 133b is provided with a second channel 1332. The second housing 131b is provided with a driving gas port 1307, an air inlet port 1305, and an air outlet port 1306. The air inlet port 1305 is in communication with the air inlet channel, and the air outlet port 1306 is in communication with the air outlet pipe 101. The driving gas port 1307 is in communication with the air cavity of the pneumatic valve. When the second channel 1332 is in communication with the driving gas port 1307 and the air inlet port 1305, the pneumatic valve is in communication with the air inlet channel. When the second channel 1332 is in communication with the driving gas port 1307 and the air outlet port 1306, the pneumatic valve is in communication with the air outlet pipe 101.

[0080] The gas flow ports (such as the driving gas port 1307, the air inlet port 1305 and the air outlet port 1306) are arranged on the shell, the passages are arranged on the corresponding valve core, and the opening and closing of the sewage pipeline 160 can be realized by switching the communication of the passages and different gas flow ports, and the structure is more simple and compact. Further, on the basis of the structure, the communication of the passages and different gas flow ports can be realized by rotating the valve core 130 of the control valve 130 relative to the shell, and the convenience of the structure setting of driving and position detection and the like can be further reduced.

[0081] In some embodiments, the first valve core 133a is rotatably installed in the first shell 131a, the second valve core 133b is rotatably installed in the second shell 131b, and the first valve core 133a and the second valve core 133b are rotated to different angles to correspond to different liquid flow ports and gas flow ports. Please refer to Figure 21 , the first valve core 133a includes a first passage 1331, and the second valve core 133b includes a second passage 1332. In the process of rotating the first valve core 133a relative to the first shell 131a and rotating the second valve core 133b relative to the second shell 131b, the passages of the valve core 133 of the control valve 130 are switched in communication with each liquid flow port (please refer to Figure 10 and Figure 11 ) and each gas flow port (please refer to Figure 16 ). By arranging the above control valve 130, the control of the cleaning water supplement and the sewage pumping control can make the integration of the valve structure, driving and control higher, and save the base station space.

[0082] Please refer to Figure 3 and Figure 17 , in an embodiment of the cleaning base station of the present application, the on-off assembly 150 includes a pneumatic valve installed on the sewage pipeline 160, the second shell 131b further includes a driving gas port 1307, the driving gas inlet of the pneumatic valve is in communication with the driving gas port 1307, and the driving gas inlet and the driving gas port 1307 can be directly connected or indirectly connected. In the present embodiment, the driving gas inlet can be in communication with the driving gas port 1307 through the driving pipeline 104.

[0083] In the process of rotating the valve core 133 relative to the shell, the control valve 130 also has a valve driving state of blocking the air inlet port 1305 and the air outlet port 1306 and communicating the air inlet port 1305 and the driving gas port 1307 through the second passage 1332.

[0084] The pneumatic pinch valve can realize exhaust by additionally arranging a pressure relief port, so as to open the sewage pipeline 160. Preferably, in an embodiment of the cleaning base station of the present application, the pressure relief port and the driving gas inlet on the pneumatic valve are the same interface. Please refer to Figure 18, the control valve 130 also has a valve exhaust state in which the second spool 133b is rotated relative to the second housing 131b, and the second passage 1332 is in communication with the gas inlet port 1305 and the drive gas port 1307, in the valve exhaust state, the gas in the pneumatic valve cavity is exhausted from the cavity, the pneumatic valve is switched to the conductive state, and the sewage pipeline 160 can perform sewage pumping.

[0085] In some embodiments, the gas inlet port 1305 is in communication with the exhaust port of the negative pressure device 140. The gas inlet port 1305 and the exhaust port of the negative pressure device 140 can be directly connected or indirectly connected. For example, the gas inlet port 1305 and the exhaust port of the negative pressure device 140 can be communicated through a gas inlet channel. The gas outlet port 1306 is in communication with the atmosphere, and the gas outlet port 1306 can be directly connected to the atmosphere or indirectly connected to the atmosphere, for example, the gas outlet port 1306 is communicated with the atmosphere through the exhaust pipeline 101. In this way, the control valve 130 can be switched to the valve driving state in which the second passage 1332 is in communication with the gas inlet port 1305 and the drive gas port 1307 while the negative pressure device 140 is pumping the gas from the sewage cavity 121, and the gas pumped from the sewage cavity 121 by the negative pressure device 140 can drive the pneumatic valve to act and block the sewage pipeline 160. As can be seen, the control valve 130 of the present application can drive the pneumatic valve through the negative pressure device 140, without the need to additionally provide the negative pressure device 140, other valves or adapters, so as to block and conduct the sewage pipeline 160, simplify the system design, reduce the manufacturing and maintenance costs, and save the internal space of the base station.

[0086] In some embodiments, when the second passage 1332 is in communication with the gas inlet port 1305 and the gas outlet port 1306, the negative pressure device 140 extracts the gas in the sewage cavity 121 and discharges it through the gas outlet port 1306. For example, when the on-off assembly 150 is in the blocking state, the second passage 1332 of the second spool 133b is controlled to be in communication with the gas inlet port 1305 and the gas outlet port 1306, and the negative pressure device 140 performs the gas pumping operation on the sewage cavity 121. When the negative pressure value in the sewage cavity 121 reaches the requirement, the second passage 1332 of the second spool 133b can be controlled to be in communication with the gas cavity of the pneumatic valve and the gas outlet port 1306, the gas in the gas cavity of the pneumatic valve is discharged, the pneumatic valve is switched to the conductive state, the sewage pipeline 160 is conducted, and based on the negative pressure in the sewage cavity 121, the sewage in the cleaning tank 180 enters the sewage cavity 121 through the sewage pipeline 160. In this way, the same control valve 130 can be used to control the negative pressure pumping of the sewage cavity 121, the blocking of the sewage pipeline 160 and the conducting of the sewage pipeline 160, greatly reducing the number of parts of the control valve 130, simplifying the overall structure, and thus reducing the production cost.

[0087] Please refer to Figure 3 , Figure 5 and Figure 10In the embodiment of the cleaning base station, the first outlet 1304 is in communication with the host water replenishing pipeline 171, and the control valve 130 has a host water delivery state of communicating the inlet 1301 and the first outlet 1304 through the first channel 1331 in the process of rotating the first valve core 133a relative to the first shell 131a. In this state, the inlet 1301 is in communication with the first outlet 1304, and the cleaning water in the cleaning water chamber 110 flows into the host water replenishing pipeline 171 under the action of gravity or the cleaning water pump, thereby providing water supply for the cleaning water box of the host.

[0088] Please refer to Figure 3 , Figure 5 and Figure 13 In the embodiment of the cleaning base station, the first shell 131a further includes a vent 1303 in communication with the atmosphere, and the vent 1303 is in communication with the atmosphere through the exhaust pipeline 101, and the position of the exhaust pipeline 101 in communication with the atmosphere is above the highest liquid level of the cleaning water chamber 110. The control valve 130 further has a host water replenishing pipeline 171 anti-siphon state of communicating the inlet 1301, the vent 1303 and the first outlet 1304 through the first channel 1331 in the process of rotating the first valve core 133a relative to the first shell 131a. By rotating the first valve core 133a to communicate the inlet 1301, the vent 1303 and the first outlet 1304, the first outlet 1304 is in communication with the atmosphere, thereby breaking the siphon condition that may be formed, and effectively preventing the siphon effect of the host water replenishing pipeline 171 on the cleaning water chamber 110 when the liquid delivery is stopped.

[0089] In the embodiment of the cleaning base station, the control valve 130 further has a cleaning water delivery state of communicating the inlet 1301 and the second outlet 1302 through the first channel 1331 in the process of rotating the first valve core 133a relative to the first shell 131a. When the host enters the cleaning tank 180, the inlet 1301 can be communicated with the second outlet 1302 through the control valve 130, so that the cleaning water in the cleaning water chamber 110 can flow into the cleaning pipeline 172 under the action of gravity or the cleaning water pump, thereby providing cleaning water supply for cleaning of the cleaning parts of the host.

[0090] It should be noted that in other embodiments, the water delivery pipeline 170 can only include the host water replenishing pipeline 171 or the cleaning pipeline 172, so that the corresponding control valve 130 can only have the first outlet 1304 or the second outlet 1302. When the water delivery pipeline 170 includes the host water replenishing pipeline 171 and the cleaning pipeline 172, the corresponding control valve 130 has the first outlet 1304 and the second outlet 1302.

[0091] The first liquid outlet 1304 is communicated with the host water supplement pipeline 171, and the second liquid outlet 1302 is communicated with the cleaning pipeline 172. In the process of rotating the first valve core 133a relative to the first shell 131a, the control valve 130 has the host liquid conveying state of communicating the first liquid outlet 1304 with the first liquid inlet 1301 through the first channel 1331 and the cleaning liquid conveying state of communicating the second liquid outlet 1302 with the first liquid inlet 1301 through the first channel 1331. The host liquid conveying state and the cleaning liquid conveying state can be mutually exclusive, that is, in the process of rotating the valve core 133, only one of the first channel 1331 can be communicated with the first liquid outlet 1304 and the second liquid outlet 1302. The host liquid conveying state and the cleaning liquid conveying state can also be simultaneously present, that is, in the process of rotating the first valve core 133a, the first channel 1331 can be simultaneously communicated with the first liquid outlet 1304 and the second liquid outlet 1302. Such a setting not only enables the cleaning base station to have more function integration, but also enables the same control valve 130 to integrate the control of multiple liquid conveying pipelines 170, thereby saving costs and simplifying the installation process of the water pipeline.

[0092] In an embodiment of the cleaning base station, the first shell 131a further comprises a vent 1303 communicated with the atmosphere, the vent 1303 is communicated with the atmosphere through an exhaust pipeline 101, and the position of the exhaust pipeline 101 communicated with the atmosphere is located above the highest liquid level of the clean water tank. In the process of rotating the first valve core 133a relative to the first shell 131a, the control valve 130 further has the cleaning liquid conveying pipeline 170 anti-siphon state of simultaneously communicating the vent 1303 and the second liquid outlet 1302 with the first liquid inlet 1301 through the first channel 1331. Similar to the host water supplement pipeline 171 anti-siphon state, the rotation of the first valve core 133a simultaneously communicates the vent 1303 and the second liquid outlet 1302 with the first liquid inlet 1301, so that the second liquid outlet 1302 is communicated with the atmosphere, thereby preventing the siphon effect of the cleaning liquid conveying pipeline 170 on the clean water cavity 110 after the cleaning is completed.

[0093] It should be noted that in the present application, the control valve 130 can only include the cleaning liquid conveying pipeline 170 anti-siphon state or the host water supplement pipeline 171 anti-siphon state, the vent 1303 is communicated with the atmosphere through the exhaust pipeline 101, and the position of the exhaust pipeline 101 communicated with the atmosphere is located above the highest liquid level of the clean water tank. In the process of rotating the first valve core 133a relative to the shell, the control valve 130 has the host water supplement pipeline 171 anti-siphon state of simultaneously communicating the vent 1303 and the first liquid outlet 1304 with the first liquid inlet 1301 through the first channel 1331, and the cleaning liquid conveying pipeline 170 anti-siphon state of simultaneously communicating the vent 1303 and the second liquid outlet 1302 with the first liquid inlet 1301 through the first channel 1331.

[0094] Vent 1303 is arranged between first liquid outlet 1304 and second liquid outlet 1302 along the rotation direction of first valve core 133a. When the main machine infusion is finished, rotating first valve core 133a can directly switch from the main machine infusion state to the anti-siphon state of main machine water supplement pipeline 171. When the infusion to cleaning tank 180 is finished, first valve core 133a can also be reversely rotated to directly switch from the cleaning infusion state to the anti-siphon state of cleaning infusion pipeline 170. Such arrangement can make the cleaning base station have more function integration, and can integrate the control of multiple infusion pipelines 170 through the same control valve 130, thereby saving cost and simplifying the installation process of the water pipeline.

[0095] The cleaning base station of the present application can not have the cleaning liquid adding function, and the adding of cleaning liquid is realized manually. Preferably, in an embodiment of the cleaning base station of the present application, the cleaning base station further comprises cleaning liquid extraction device 190, which is installed on base station main body 100. Cleaning liquid extraction device 190 extracts cleaning liquid from cleaning liquid outlet 1309 and adds the cleaning liquid into main machine water supplement pipeline 171 or cleaning pipeline 172.

[0096] In an embodiment of the cleaning base station of the present application, the cleaning base station further comprises multiple cleaning liquid pipelines, and control valve 130 further comprises third valve section 130c, which comprises third valve core 133c. Third valve core 133c switches any one of the multiple cleaning liquid pipelines to be communicated with main machine water supplement pipeline 171 or cleaning pipeline 172 when moving. When control valve 130 further comprises first valve core 133a, first valve core 133a and third valve core 133c move synchronously. When control valve 130 further comprises second valve core 133b, second valve core 133b and third valve core 133c move synchronously. When control valve 130 further comprises first valve core 133a and second valve core 133b, first valve core 133a, second valve core 133b and third valve core 133c move synchronously. The synchronous movement part can refer to the above-mentioned embodiments, which will not be described here. The switching control of the cleaning water circuit is realized through first valve section 130a, the opening and closing control of sewage pipeline 160 is realized through second valve section 130b, and the adding control of cleaning liquid is realized through third valve section 130c. Multiple control valves 130 are not needed, the installation circuit can be simplified, and the space of the base station is saved.

[0097] In an embodiment of the cleaning base station of the present application, the third valve section 130c can include a third housing 131c including a cleaning liquid outlet 1309 and a plurality of cleaning liquid inlets 1308 respectively communicating with different cleaning liquid pipelines, and a third valve core 133c including a third channel 1333, when the third channel 1333 communicates with the cleaning liquid outlet 1309 and any cleaning liquid inlet 1308, the cleaning liquid inlet 1308 corresponding cleaning liquid pipeline communicates with the main machine water supplement pipeline 171 or the cleaning pipeline 172. The liquid flow ports (such as the cleaning liquid outlet 1309 and the plurality of cleaning liquid inlets 1308) are arranged on the housing, and the channel is arranged on the valve core 133, and by switching the communication of the channel with different liquid flow ports, the switching of multiple cleaning liquids can be realized, and the structure is more simple and compact. Further, on the basis of this structure, the rotation of the control valve 130 core relative to the housing can realize the communication of the channel with different liquid flow ports, and the simplicity of the structure setting of driving and position detection can also be reduced.

[0098] The cleaning liquid outlet 1309 can only communicate with the water cavity 110 or the liquid inlet 1301 through the cleaning liquid adding pipeline 102, or can simultaneously communicate with the water cavity 110 and the liquid inlet 1301 through the cleaning liquid adding pipeline 102. The cleaning liquid inlet 1308 communicates with the cleaning liquid storage cavity, which can be arranged on the base station main body 100 or directly as the inner cavity of the cleaning agent storage bottle.

[0099] The first valve core 133a, the second valve core 133b, and the third valve core 133c can also be connected in other ways. For details, reference can be made to the connection mode of the first valve core 133a and the second valve core 133b described above, which will not be repeated here. In an embodiment of the cleaning base station of the present application, at least two of the first valve core 133a, the second valve core 133b, and the third valve core 133c are integrally formed to form an integral valve core 133. For example, any two of the first valve core 133a, the second valve core 133b, and the third valve core 133c can be integrally formed, or the first valve core 133a, the second valve core 133b, and the third valve core 133c can be integrated on one valve core 133. Specifically, in the present embodiment, the first valve core 133a, the second valve core 133b, and the third valve core 133c are integrated on one valve core 133 and integrally formed, so that no additional parts need to be installed, which can improve the assembly efficiency and installation accuracy.

[0100] The relative positions between the first valve core 133a, the second valve core 133b, and the third valve core 133c can be flexibly adjusted according to the arrangement mode of the pipelines in the base station. For example, in the case of coaxial rotation of the integrally formed first valve core 133a, the second valve core 133b, and the third valve core 133c, the first valve core 133a, the second valve core 133b, and the third valve core 133c can be distributed in sequence along the axial direction of the valve core. For example,Figure 2 and Figure 5 As shown in FIG. 13, if the axial direction of the control valve is the height direction of the base station, the first valve core 133a can be arranged at the uppermost end to facilitate the arrangement of the anti-siphon pipeline, the second valve core 133b is arranged in the middle, and the third valve core 133c is arranged at the lowermost end. Of course, the axial direction of the valve core and the distribution position of each valve core can be flexibly adjusted by those skilled in the art according to the pipeline arrangement.

[0101] In an embodiment of the cleaning base station, at least two of the first shell 131a, the second shell 131b, and the third shell 131c are integrally formed. For example, any two of the first shell 131a, the second shell 131b, and the third shell 131c can be integrally formed, or the first shell 131a, the second shell 131b, and the third shell 131c can be integrally formed. Specifically, in this embodiment, the first shell 131a and the second shell 131b are integrally formed to facilitate assembly, and the third shell 131c is detachably connected to the second shell 131b.

[0102] In some embodiments, the first shell 131a of the control valve 130 is provided with a cleaning liquid adding port 1310, the cleaning liquid adding port 1310 is in communication with the liquid inlet 1301, one end of the cleaning liquid adding pipeline 102 is in communication with the cleaning liquid outlet 1309, and the other end of the cleaning liquid adding pipeline 102 is in communication with the cleaning liquid adding port 1310. Under the action of the cleaning liquid extraction device 190, the cleaning liquid in the cleaning liquid storage cavity enters the clean water cavity 110 and / or the liquid inlet 1301 in sequence through the cleaning liquid inlet 1308, the cleaning liquid outlet 1309, and the cleaning liquid adding pipeline 102. By arranging the cleaning liquid storage cavity and the cleaning liquid extraction device 190, mounting them on the base station main body 100, and designing the communication mode of the cleaning liquid outlet 1309, the inlet, and the cleaning liquid adding pipeline 102, the cleaning liquid can be automatically extracted from the storage cavity through the cleaning liquid extraction device 190, and then enters the clean water cavity 110 and / or the liquid inlet 1301 through the pipeline, without the need for manual addition of cleaning liquid, greatly improving the automation degree of the cleaning base station, reducing the tediousness of manual operation, and improving the cleaning efficiency.

[0103] If different cleaning scenarios are not considered, only one cleaning liquid storage cavity can be arranged in the cleaning base station, and only one corresponding cleaning liquid inlet 1308 can be arranged. Alternatively, two cleaning liquid storage cavities can be arranged, and two corresponding cleaning liquid inlets 1308 can be arranged, so that one cleaning liquid inlet 1308 is in communication with one of the cleaning liquid storage cavities, and the other cleaning liquid inlet 1308 is in communication with the other cleaning liquid storage cavity. Of course, more cleaning liquid storage cavities can be arranged in sequence, and more cleaning liquid inlets 1308 can be arranged in correspondence.

[0104] In an embodiment, the cleaning task of the host has multiple different scenes, and different cleaning liquids need to be used for different scenes. Therefore, the cleaning base station includes multiple cleaning liquid storage cavities for storing different cleaning liquids, and different cleaning liquids are used for different cleaning scenes. For example, when the host performs cleaning for different room areas or different dirty areas such as hard floor cleaning, bathroom cleaning, kitchen cleaning, and the like, the host can be supplemented with different cleaning liquids to make the cleaning of the corresponding area more targeted and improve the cleaning effect. The housing of the control valve 130 includes multiple cleaning liquid inlets 1308, which are equal in number to the multiple cleaning liquid storage cavities and are respectively connected in communication. Of course, different cleaning liquids can also be added for the cleaning piece washing task of the host. For example, different cleaning liquids can be used to wash the cleaning piece when the host performs cleaning for different room areas or different dirty areas or after cleaning. For example, after the cleaning piece cleans the feces area, a deodorant can be further added when the cleaning piece is washed to remove the odor on the cleaning piece, and the like.

[0105] In an embodiment, the third housing 131c can include seven cleaning liquid inlets 1308, and each cleaning liquid inlet 1308 is connected in communication with one cleaning liquid storage cavity. The third valve core 133c further includes a third channel 1333, and the two ends of the third channel 1333 are respectively a cleaning liquid inlet interface 13331 and a cleaning liquid outlet interface 13332. The cleaning liquid inlet interface 13331 is arranged on the circumferential wall body of the third valve core 133c, and the cleaning liquid outlet interface 13332 is arranged on the end wall of the second column end 1335 of the third valve core 133c. During the rotation of the third valve core 133c relative to the third housing 131c, the cleaning liquid inlet interface 13331 rotates with the third valve core 133c and is sequentially connected with different cleaning liquid inlets 1308, so that the third channel 1333 sequentially connects the cleaning liquid outlet 1309 with different cleaning liquid inlets 1308.

[0106] Through the design of the multiple cleaning liquid storage cavities and the multiple cleaning liquid inlets 1308, different types of cleaning liquids can be stored, such as special cleaning liquids for different types of stains or cleaning requirements, so that the cleaning base station has the ability to use multiple cleaning liquids to meet various cleaning scenes and requirements, thereby improving the applicability and flexibility of the cleaning base station. At the same time, the control valve 130 integrates the first valve segment 130a, the second valve segment 130b, and the third valve segment 130c in one valve core 133, which not only realizes the switching of the cleaning water supply, but also realizes the switching of the conduction and blockage of the sewage pipeline 160, and can realize the flexible switching of supplementing different types of cleaning liquids to the host water supplement pipeline and the washing pipeline respectively or to the host water supplement pipeline / washing pipeline, so that different cleaning liquids can be quickly switched during the cleaning process as needed, thereby further improving the timeliness and convenience of cleaning liquid addition.

[0107] The following is an example of adding multiple cleaning liquids to the host water supply pipeline.

[0108] Please refer to Figure 8 , Figure 14 and Figure 19 , in an embodiment of the present application, the first housing 131a includes a first liquid outlet 1304 and a liquid storage groove 1323 arranged on the inner wall of the first housing 131a, the first liquid outlet 1304 is in communication with the host water supply pipeline 171, the liquid storage groove 1323 is partially arranged around the outer periphery of the first valve core 133a, and the first liquid outlet 1304 or the second liquid outlet 1302 communicates with the liquid storage groove 1323. During the rotation of the first valve core 133a and the keeping of the first channel 1331 in communication with the liquid storage groove 1323, the third valve core 133c makes the cleaning liquid outlet 1309 in turn communicate with at least two cleaning liquid inlets 1308 corresponding to the host water supply pipeline.

[0109] Specifically, the first channel 1331 includes a liquid inlet interface 13311 and a liquid outlet interface 13312, the liquid inlet interface 13311 is always in communication with the liquid inlet 1301 on the housing during the rotation of the valve core 133, and the liquid outlet interface 13312 is arranged on the side wall of the valve core 133. During the rotation of the valve core 133 and the keeping of the first channel 1331 in communication with the liquid storage groove 1323, the liquid outlet interface 13312 is rotated from one end of the liquid storage groove 1323 to the other end of the liquid storage groove 1323 along the circumference of the valve core 133, so that the liquid outlet interface 13312 is in communication with the first liquid outlet 1304 during the process. It should be noted that during the rotation of the liquid outlet interface 13312 from one end of the liquid storage groove 1323 to the other end of the liquid storage groove 1323, the cleaning liquid inlet interface 13331 on the third channel 1333 will also rotate by a corresponding angle, and at least two different cleaning liquid inlets 1308 corresponding to the corresponding host water supply pipeline are arranged on the housing corresponding to the angle range of the rotation of the cleaning liquid inlet interface 13331, that is, different cleaning liquids can be added to the host water supply pipeline 171.

[0110] In the case of adding multiple cleaning liquids to the host water supply pipeline 171, this design avoids frequent replacement of cleaning liquids or the setting of multiple independent adding devices, greatly improves the flexibility and diversity of cleaning liquid addition, and meets different cleaning needs. And the integration of the valve body and the pipeline is high, the overall structure of the valve body is simple and compact, and the control of the valve body is also simple.

[0111] The following is an example of adding multiple cleaning liquids to the host water supply pipeline.

[0112] Please refer toFigure 19 In an embodiment of the present application, the shell comprises seven cleaning liquid inlets 1308, and the third channel 1333 enables the cleaning liquid outlet 1309 to be sequentially communicated with the six cleaning liquid inlets 1308 during the rotation and the maintaining of the first channel 1331 in communication with the liquid storage groove 1323 by the valve core 133. Such an arrangement can enable the addition of six different cleaning liquids into the main machine water supplement pipeline 171 in one rotation cycle of the valve core 133, and can meet more cleaning requirements of the main machine. The other cleaning liquid inlet 1308 corresponds to the cleaning pipeline, so that the cleaning liquid can be supplemented to the cleaning pipeline while the cleaning liquid is supplemented to the main machine water supplement pipeline. Of course, if the cleaning pipeline also needs to be supplemented with multiple cleaning liquids, the above-mentioned embodiments can be referred to for implementation, and details are not repeated here.

[0113] In the present application, the cleaning liquid extraction device 190 can also be arranged on the pipeline between the cleaning liquid storage cavity and the cleaning liquid inlet 1308. Preferably, in an embodiment of the cleaning base station of the present application, the cleaning liquid extraction device 190 is arranged on the cleaning liquid supplement pipeline 102. Arranging the cleaning liquid extraction device 190 on the cleaning liquid supplement pipeline 102 can extract the cleaning liquid in multiple cleaning liquid storage cavities through one cleaning liquid extraction device 190, and the valve 130 core can be rotated to the appropriate position according to the actual cleaning requirements, so as to accurately extract the required cleaning liquid, which not only reduces the cost, but also improves the compactness of the installation.

[0114] In an embodiment of the cleaning base station of the present application, the cleaning liquid extraction device 190 is a peristaltic pump. The peristaltic pump has a unique extrusion conveying principle, which pushes the cleaning liquid forward in the pipeline by rolling and extruding the hose of the pump head, and can realize efficient and stable extraction of the cleaning liquid. Even in the case of high viscosity of the cleaning liquid or the presence of certain resistance in the pipeline, the peristaltic pump can also maintain good extraction effect and ensure smooth delivery of the cleaning liquid, providing continuous and stable cleaning liquid supply for the cleaning base station. Moreover, the structure of the peristaltic pump is relatively simple, and the key component, the hose, is directly contacted with the cleaning liquid during use, while other components such as the pump head are not directly contacted with the cleaning liquid. This makes the peristaltic pump more convenient to maintain and clean, and only the hose needs to be replaced regularly, which reduces the maintenance cost and difficulty, and also helps to maintain the hygiene and cleanliness of the cleaning liquid extraction device 190, avoiding the influence of internal pollution on the cleaning effect of the cleaning liquid.

[0115] In the present application, the position of the valve core 133 relative to the shell can also be determined by setting a scale on the shell and a pointer on the valve core 133, and determining the position of the valve core 133 relative to the shell by the relationship between the pointer and the scale. Preferably, considering the need for automation, in an embodiment of the cleaning base station of the present application, the control valve 130 further comprises a position detection device 1313 for detecting the position of the valve core 133 relative to the shell. The first valve core 133a, the second valve core 133b, and the third valve core 133c are coaxially rotatably installed in the shell, and the position detection device 1313 detects the position of any one of the first valve core 133a, the second valve core 133b, and the third valve core 133c relative to the shell. Through the position detection device 1313, the position information of the valve core 133 can be more accurately obtained, so as to realize accurate control of the rotation angle and position of the valve core 133, which is crucial for operations involving switching of multiple cleaning liquids, conversion of different cleaning modes, and other operations that require accurate control of the position of the valve core 133 in the cleaning base station. In this way, the control system of the cleaning base station can control the rotation of the valve core 133 according to the signal of the position detection device 1313, so as to ensure that the cleaning base station can accurately perform various actions according to the preset program and requirements, thereby improving the control accuracy and reliability of the cleaning base station.

[0116] In the present application, the position detection device 1313 can be any suitable type of device that can detect the position of the valve core 133 relative to the shell, such as a magnetic induction type position sensor, a Hall type position sensor, and an optical type position sensor. In an embodiment of the cleaning base station of the present application, the position detection device 1313 comprises a detection element 13131 and a sensing element 13132, the sensing element 13132 is fixedly installed on the valve core 133, and the detection element 13131 is fixedly installed on the shell and corresponds to the position of the sensing element 13132. The cooperation of the detection element 13131 and the sensing element 13132 makes the position detection process stable and reliable, and is not easily affected by external interference, so as to continuously and accurately provide feedback information of the position of the valve core 133 to the control system, thereby providing a strong guarantee for the accurate control of the cleaning base station. At the same time, this split type installation of the detection element 13131 and the sensing element 13132 makes it possible to separately install the detection element 13131 on the shell and the sensing element 13132 on the valve core 133 during the assembly of the cleaning base station, which is relatively simple and convenient.

[0117] In an embodiment of the cleaning base station of the present application, the detection element 13131 comprises a Hall sensor, and the inductive element 13132 comprises a magnetic element. The Hall sensor as the detection element 13131 has the characteristics of high precision and high sensitivity, and can quickly and accurately respond to the slight changes of the magnetic field. The magnetic element as the inductive element 13132 is fixedly connected with the valve core 133, and the magnetic field changes during the rotation of the valve core 133. The Hall sensor can accurately detect these changes of the magnetic field, thereby realizing high-precision detection of the position of the valve core 133. Even in the case that the rotation angle of the valve core 133 is small or the position change is slight, the position information can be accurately captured, thereby providing technical support for fine control of the cleaning base station.

[0118] In the present application, the detection element 13131 can be installed on the shell in various ways, for example, it can be clamped to the shell, or it can be directly fixed to the shell through a bolt assembly, but it is not limited thereto. Preferably, in an embodiment of the cleaning base station of the present application, the control valve 130 further comprises a stopper 1314, and the shell is provided with a clamping groove. The detection element 13131 is clamped into the clamping groove from the opening of the clamping groove, and the stopper 1314 is installed in the slot of the clamping groove and stops the detection element 13131. With this structure, when the detection element 13131 fails or needs to be replaced, the stopper 1314 can be removed, and the detection element 13131 can be easily taken out of the clamping groove for replacement or maintenance operation, without the need to disassemble the entire control valve 130 or the shell, thereby reducing the maintenance cost and difficulty, and improving the maintainability of the cleaning base station.

[0119] In the present application, the control valve 130 can not comprise the inductive element mounting bracket 13133, but the inductive element 13132 is directly fixed on the valve core 133. Preferably, in an embodiment of the cleaning base station of the present application, the control valve 130 further comprises the inductive element mounting bracket 13133. An installation groove is arranged on the end face of the valve core 133 close to the detection element 13131. The installation groove can have any shape that is not a rotationally symmetrical shape, so that the inductive element mounting bracket 13133 can be inserted into the installation groove and driven to rotate with the valve core 133. The inductive element mounting bracket 13133 is inserted into the installation groove, and the inductive element 13132 is mounted on the inductive element mounting bracket 13133. The inductive element mounting bracket 13133 not only can support and fix the inductive element 13132, but also can be arranged away from the water inlet. When the inductive element 13132 needs to be replaced, calibrated or adjusted, the inductive element mounting bracket 13133 can be pulled out of the installation groove, so that the inductive element 13132 can be conveniently operated without the need to complicate the valve core 133, thereby improving the operability and flexibility of the inductive element 13132, and facilitating the smooth maintenance and debugging of the cleaning base station.

[0120] Although the control valve 130 in the present application can be manually controlled by hand. Preferably, the cleaning base station has a control system. In an embodiment of the cleaning base station of the present application, the control valve 130 further comprises a driving device 134, which drives the synchronous movement of the valve cores, such as driving the synchronous rotation of the first valve core 133a and the second valve core 133b in the housing. The position detection device 1313 and the driving device 134 are both electrically connected to the control system of the cleaning base station. The position detection device 1313 feeds back signals to the control system, and the control system controls the action of the driving device 134 according to the signals of the position detection device 1313, so as to control the rotation or stop of the valve 130 core. By driving the valve core 133 to rotate in the housing through the driving device 134, the rotation of the valve core 133 is no longer dependent on manual operation or other non-automatic driving mode, and automatic control of the valve core 133 is realized. This provides key technical support for the automatic operation of the cleaning base station. According to the preset program or control instruction, the rotation angle and position of the valve 130 core can be automatically and accurately controlled, so as to realize the automatic switching of the cleaning liquid, the automatic conversion of the cleaning mode and other functions, and greatly improve the intelligent level and working efficiency of the cleaning base station.

[0121] As long as the movement of the valve core 133 can be realized, the type of the driving device 134 in the present application is not limited. Considering the low rotation speed of the valve core 133, please refer to Figure 8 In an embodiment of the cleaning base station of the present application, the driving device 134 comprises a motor and a speed reduction mechanism. The output shaft 1341 of the motor is connected with the input end of the speed reduction mechanism, and the output end of the speed reduction mechanism is connected with any one of the first valve core 133a, the second valve core 133b and the third valve core 133c. The driving device 134 adopts the combination form of the motor and the speed reduction mechanism. The motor serves as a power source and can provide stable and controllable power output, and the speed reduction mechanism can slow down the high-speed rotation of the motor and then transmit it to the valve core 133, so that the valve core 133 can rotate smoothly and accurately at a low speed.

[0122] The type of the speed reduction mechanism in the present application is not limited, which can be a chain transmission speed reduction structure, a belt transmission speed reduction structure, a gear speed reduction structure or a combination of the above structures. Preferably, please refer to Figure 20In an embodiment of the cleaning base station of the present application, the speed reduction mechanism comprises a meshing gear assembly, which at least comprises an input gear 1342 and an output gear 1343, the input gear 1342 is fixedly connected with the output shaft 1341 of the motor, and the output gear 1343 is on any one of the first valve core 133a, the second valve core 133b and the third valve core 133c. The gear meshing transmission has the characteristics of high transmission accuracy, stable transmission ratio, good torque amplification effect, etc., and can accurately transmit the power of the motor to the valve core 133, and realize the amplification of the torque according to the gear tooth ratio, so that the valve core 133 can obtain sufficient torque to drive its rotation under smaller motor power, meet the requirements of the cleaning base station on the rotation torque of the valve core 133, and improve the transmission efficiency and power utilization effect of the system. Those skilled in the art can understand that a transmission gear can also be arranged between the input gear 1342 and the output gear 1343 according to the need for speed reduction.

[0123] In an embodiment of the cleaning base station of the present application, the shell further comprises an outer shell 131 and an inner shell 132, the outer shell 131 is made of a hard material, and the inner shell 132 is made of a material with elasticity. The inner shell 132 is fixed to the inner side of the outer shell 131 and is compressed between the outer shell 131 and the valve core 133. The outer shell 131 made of a hard material has high strength and rigidity, can withstand large external pressure and load, and provides stable support and protection for the valve core. The addition of the inner shell 132 makes the shell have good elasticity and sealing performance on the basis of maintaining a certain strength, not only can form a good seal between the outer shell 131 and the valve core 133, but also provides conditions for the sealed docking between the valve core 133 and the interfaces on the shell during rotation.

[0124] In one example, the shell comprises a first shell and a second shell, and correspondingly, the first shell comprises a first inner shell and a first outer shell, and the second shell comprises a second inner shell and a second outer shell. In an embodiment of the cleaning base station of the present application, the shell further comprises a first inner shell 1321 and a second inner shell 1322, and the first outer shell 1311 and the second outer shell 1312 are both made of a hard material, and the first inner shell 1321 and the second inner shell 1322 are made of a material with elasticity. The first inner shell 1321 is fixed to the inner side of the first outer shell 1311 and is compressed between the first outer shell 1311 and the valve core 133. The second inner shell 1322 is fixed to the inner side of the second outer shell 1312 and is compressed between the second outer shell 1312 and the valve core 133.

[0125] In one embodiment of the clean base station of the present invention, the valve core 133 is rotatably mounted on the outer shell 131 at both ends along the rotation axis direction, and the inner shell 132 is fixed to the inner side of the outer shell 131 and compressed between the outer shell 131 and the valve core 133. To facilitate the installation of the valve core 133, the outer shell 131 includes a first outer shell 1311 and a second outer shell 1312, and the inner shell 132 includes a first inner shell 1321 and a second inner shell 1322. Correspondingly, the upper end of the valve core 133 is provided with a first post end 1334, and the lower end of the valve core 133 is provided with a second post end 1335. The first post end 1334 and the second post end 1335 are coaxially arranged. The first post end 1334 is rotatably mounted on the first outer shell 1311, and the second post end 1335 is rotatably mounted on the second outer shell 1312. Installing the valve core 133 on the outer shell 131 made of rigid material can ensure the rotational accuracy of the valve core 133. The elastic inner shell 132 is compressed and disposed between the valve core 133 and the outer shell 131, which provides a guarantee for the sealing and docking of the valve core 133 and the various interfaces on the shell.

[0126] It should be noted that, provided that the valve core 133 can be installed, the outer shell 131 and / or the inner shell 132 can also be an integral structure, and do not need to be divided into a first outer shell 1311, a second outer shell 1312, or a first inner shell 1321 and a second inner shell 1322.

[0127] In this invention, the gear can be located outside the housing or between the housings corresponding to two valve sections.

[0128] Please see Figure 8 The housing includes a first outer shell 1311 and a second outer shell 1312. The first outer shell 1311 and the second outer shell 1312 are sealed together to form a gearbox for housing the gear assembly, which is located inside the gearbox. This structural design effectively protects the gear assembly, preventing dust, impurities, etc., from entering the gearbox and causing wear or jamming of the gears. It also avoids external impacts and interference to the gears during operation, ensuring the stability and smoothness of the gear transmission, extending the service life of the gear assembly, and improving the reliability and stability of the cleaning base station.

[0129] In this invention, if the first channel 1331, the second channel 1332, and the third channel 1333 are all located on one side of the output gear 1343, the output gear 1343 can also extend out of the housing, thus eliminating the need for a sealing structure between the output gear 1343 and the housing.

[0130] Please see Figure 8In the embodiment, the output gear 1343 is arranged in the gear box in the housing, and the first channel 1331, the second channel 1332 and the third channel 1333 are arranged on both sides of the output gear 1343. In order to obtain a better sealing effect, in the embodiment of the cleaning base station, the output gear 1343 is arranged between the first inner shell 1321 and the second inner shell 1322, and the side end wall of the output gear 1343 is in dynamic sealing cooperation with the first inner shell 1321 through the first sealing structure, and the other side end wall of the output gear 1343 is in dynamic sealing cooperation with the second inner shell 1322 through the second sealing structure. The examples of the gears arranged between the housings of the other two valve sections are similar and will not be described herein. The dynamic sealing design can effectively prevent the leakage of cleaning liquid, gas and other media from the gap between the output gear 1343 and the inner shell 132 during the rotation of the output gear 1343, and also avoids the entry of foreign matters into the gear box, thereby ensuring the normal transmission of the gears and the clean environment inside the cleaning base station, improving the sealing performance and reliability of the cleaning base station, and ensuring the stable operation of the cleaning base station. However, it should be noted that if the axial sealing between the valve core 133 and the inner shell 132 is good, the sealing structure can not be arranged between the output gear 1343 and the inner shell 132.

[0131] As long as the dynamic sealing between the output gear 1343 and the first inner shell 1321 and the second inner shell 1322 can be achieved, the types of the first sealing structure and the second sealing structure in the embodiment are not limited, for example, an O-ring can be arranged between the first inner shell 1321, the second inner shell 1322 and the two side end faces of the output gear 1343, but the present application is not limited thereto. Please refer to FIG. 1 and FIG. 2, in the embodiment of the cleaning base station, the first sealing structure comprises at least one first circular annular protrusion 13211 arranged on the side of the first inner shell 1321 close to the output gear 1343, the first circular annular protrusion 13211 is coaxially arranged with the output gear 1343 and is sealingly abutted to the end wall of the output gear 1343 close to the first inner shell 1321. And / or. The second sealing structure comprises at least one second circular annular protrusion 13221 arranged on the side of the second inner shell 1322 close to the output gear 1343, the second circular annular protrusion 13221 is coaxially arranged with the output gear 1343 and is sealingly abutted to the end wall of the output gear 1343 close to the second inner shell 1322. The examples of the gears arranged between the housings of the other two valve sections are similar and will not be described herein.

[0132] By making the elastic circular protrusions tightly fit with the end wall of the output gear 1343, a good sealing effect can be achieved. The protruding shape of the circular protrusions can be adjusted in size, shape and number as needed to adapt to different sealing requirements and working conditions, improving the reliability and adaptability of the seal. In addition, this sealing structure can maintain good sealing performance over a long period of use due to its reasonable stress distribution and material properties, and is not prone to aging, wear or deformation, thereby prolonging the service life of the sealing structure and reducing the maintenance cost of the cleaning base station.

[0133] Please refer to Figure 3 and Figure 8 In an embodiment of the cleaning base station, the liquid inlet 1301 is arranged on the first housing 131a at one end of the first valve core 133a, and the first housing 131a is provided with a liquid inlet cavity 1324 at a position opposite the liquid inlet 1301 inside. The cleaning liquid adding device adds cleaning liquid to the liquid inlet cavity 1324 through the cleaning liquid adding pipeline 102, and the first channel 1331 includes a liquid inlet interface 13311 arranged on the end wall of the first valve core 133a close to the liquid inlet cavity 1324 and in communication with the liquid inlet cavity 1324. This design can ensure that the liquid inlet 1301 is always in communication with the liquid inlet cavity 1324 during the rotation of the first valve core 133a, further ensuring that the cleaning water can smoothly enter the first channel 1331 inside the first valve core 133a, providing good conditions for subsequent liquid distribution and transportation, and helping to improve the operating efficiency of the entire cleaning base station.

[0134] Please refer to Figure 8 and Figure 21 In an embodiment of the cleaning base station, the first housing 131a includes a first liquid outlet 1304 and a second liquid outlet 1302, and the first channel 1331 includes a liquid outlet interface 13312 in communication with the liquid inlet interface 13311, which is arranged on the outer peripheral wall of the valve core 133. The valve core 133 has a first liquid delivery connection position (first position) and a second liquid delivery connection position (second position) during rotation. Figure 10 Figure 11 ​The liquid outlet interface 13312 on the valve core 133 is connected to the first liquid outlet 1304 in the first infusion connection position, and the entire control valve 130 switches to the host infusion state. The liquid outlet interface 13312 on the valve core 133 is connected to the second liquid outlet 1302 in the second infusion connection position, and the entire control valve 130 switches to the cleaning infusion state. The liquid outlet interface 13312 on the valve core 133 is connected to the first liquid outlet 1304 and the second liquid outlet 1302 alternately by rotation. This design enables the cleaning base station to flexibly switch the liquid output path according to different cleaning requirements or working modes, improves the applicability and flexibility of the cleaning base station, and meets the requirements of diversified cleaning tasks. At the same time, compared with setting multiple independent valve cores 133 or a complex pipeline system to realize multi-way liquid output, this switching mode by rotating the valve core 133 simplifies the structure, reduces the number and complexity of parts, and reduces the production cost and assembly difficulty.

[0135] In an embodiment of the cleaning base station, the shell further comprises a vent 1303, and the vent 1303 is connected to the atmosphere through an exhaust pipeline 101. The position where the exhaust pipeline 101 is connected to the atmosphere is located above the highest liquid level of the clean water tank. The valve core 133 has a first anti-siphon position (the position in the figure) and a second anti-siphon position (the position in the figure) in the rotation process. Figure 14 In the first anti-siphon position, the liquid outlet interface 13312 is connected to the first liquid outlet 1304 and the vent 1303 simultaneously. In the second anti-siphon position, the liquid outlet interface 13312 is connected to the second liquid outlet 1302 and the vent 1303 simultaneously. When the liquid output is stopped, the connection of the vent 1303 can balance the pressure in the pipeline in time, prevent the siphon phenomenon caused by the negative pressure in the pipeline, and improve the safety and reliability of the cleaning base station.

[0136] In an embodiment of the cleaning base station, the shell is provided with a liquid storage groove 1323, and the liquid storage groove 1323 is partially arranged around the outer periphery of the valve core 133. The first liquid outlet 1304 is connected to the liquid storage groove 1323, and the second liquid outlet 1302 is located in a region outside the liquid storage groove 1323. When the first liquid outlet interface 13312 is connected to the liquid storage groove 1323, the first liquid outlet interface 13312 is connected to the first liquid outlet 1304. The design of the liquid storage groove 1323 enhances the compactness of the structure and the convenience of the coaxial valve core in the multi-way cleaning liquid condition.

[0137] In an embodiment of the cleaning base station, the shell comprises a first liquid outlet 1304 and a second liquid outlet 1302, and the valve core 133 is connected to Figure 21In the embodiment, the first channel 1331 includes a first liquid outlet interface 13312 and a second liquid outlet interface 13312 that are in communication with the liquid inlet interface 13311. The first liquid outlet interface 13312 and the second liquid outlet interface 13312 are not in communication on the outer circumferential wall of the valve core 133, but are independently arranged like the first gas interface and the second gas interface. The first liquid outlet interface 13312 and the second liquid outlet interface 13312 are arranged on the outer circumferential wall of the valve core 133, and the inner wall of the shell is provided with a blocking portion. Similarly, the valve core 133 has a first liquid delivery connection position and a second liquid delivery connection position in the process of rotation. In the first liquid delivery connection position, the first liquid outlet interface 13312 is in corresponding communication with the first liquid outlet 1304, and the blocking portion seals and blocks the second liquid outlet interface 13312. In the second liquid delivery connection position, the second liquid outlet interface 13312 is in corresponding communication with the second liquid outlet 1302, and the blocking portion seals and blocks the first liquid outlet interface 13312.
