The change or adjustment of the relative relationship is also considered as the scope of the present application without substantial change of the technical content.

[0076] Please refer 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, etc. The cleaning base station can be used to realize one or more of the functions of charging, cleaning component washing, garbage recycling, etc. of the sweeping and mopping robot.

[0077] Please refer 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.

[0078] The shape of the base station body 100 is not limited, for example, it can be a generally 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. Considering the needs of indoor decoration, it is better to be beautiful and small in size.

[0079] 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 convenient for manufacturing, and have sufficient strength without deformation when the negative pressure is extracted to a set threshold. One end of the sewage pipeline 160 is communicated 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.

[0080] 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.

[0081] 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.

[0082] In some embodiments, the cleaning base station can further include a cleaning tank 180 for cleaning 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 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] For example, when the on-off assembly 150 is switched to the off state, the negative pressure device 140 can perform air extraction on the sewage cavity 121, so that the negative pressure in the sewage cavity 121 reaches a set threshold. When the negative pressure in the sewage cavity 121 is kept at the set threshold, the on-off assembly 150 is switched to the on 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 can be obtained by comprehensively calculating the volume of the liquid to be sucked and the diameter of the sewage pipeline 160 and the distance of the suction, or can be obtained by experiment. For example, the negative pressure threshold 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 can be 30 Kpa. In addition, it should be noted that considering the existence of errors, slight fluctuations above and below the set threshold are also "kept", and the slight fluctuations refer to ±10 Kpa.

[0087] 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 air extraction and sewage suction at the same time, a greater suction force can be obtained, which can increase the carrying rate of 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] The first valve core 133a and the second valve core 133b can be connected to form an integrated valve core 133. The first valve core 133a and the second valve core 133b can be connected to facilitate the synchronous movement of the two valve cores and improve the integration of the two valve cores. The first valve core 133a and the second valve core 133b can be connected in a detachable manner or in a fixed manner. The first valve core 133a and the second valve core 133b can also be formed in an integrated manner. The integrated design integrates the two valve cores, which were originally separately processed and assembled, into one whole, thereby reducing the number of parts and assembly steps. At the same time, the integrated first valve core 133a and the second valve core 133b are easier to control the synchronous movement of the two valve cores and do not deviate from the movement, thereby ensuring the control accuracy.

[0095] The control valve 130 can further 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 can be 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.

[0096] 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 section 130a switches the communication of the clean water chamber 110 with 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 section 130b switches the sewage pipeline 160 into any one of 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 improving the integration of the base station.

[0097] 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.

[0098] 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 core. By switching the communication between the channels and different liquid flow ports, the host water supplement pipeline 171 and the cleaning pipeline 172 can be switched, 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.

[0099] 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, air enters the air cavity through the air inlet channel. When the pneumatic valve communicates with the air outlet pipeline 101, air 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 air 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.

[0100] In some embodiments, the negative pressure device 140 is in communication with the air inlet channel, the negative pressure device 140 extracts the gas in the sewage cavity 121 and transports it to the air inlet channel, so that the gas enters 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 pipeline, 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, saving the time for continuing to extract negative pressure from the sewage cavity 121 after the sewage pipe is blocked, and 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, and the blocking of the sewage pipe will not have a great impact.

[0101] Of course, in the utility model, the air inlet channel can also be in communication with another gas pump, 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.

[0102] In an embodiment of the cleaning base station, the exhaust pipeline 101 is in communication with the atmosphere, so that the gas from the air cavity is discharged into the atmosphere, and the gas of the pneumatic valve is directly discharged into the atmosphere without the need for an additional pipeline, which can further save the internal space of the base station. Of course, in the utility model, the gas of the pneumatic valve can also be returned to the sewage cavity 121 through another pipeline, and 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.

[0103] 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 exhaust pipeline 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 exhaust pipeline 101.

[0104] 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 cores, 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, so that 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 control valve 130 core relative to the shell, and the convenience of the structure setting of driving and position detection and the like can be further reduced.

[0105] 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 structure, driving and control of the valve higher, and save the base station space.

[0106] Please refer to Figure 3 and Figure 17 , in an embodiment of the cleaning base station of the utility model, 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, a 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 embodiment, the driving gas inlet can be in communication with the driving gas port 1307 through the driving pipeline 104.

[0107] In the process of rotating the valve core 133 relative to the shell, the control valve 130 further 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.

[0108] 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 utility model, 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 further has a valve exhaust state in which the second passage 1332 of the second valve core 133b is communicated with the air inlet 1305 and the air outlet 1306, in the valve exhaust state, the gas in the pneumatic valve cavity is exhausted, the pneumatic valve is switched to the conductive state, and the sewage pipeline 160 can perform the sewage pumping operation.

[0109] In some embodiments, the air inlet 1305 is communicated with the exhaust port of the negative pressure device 140. The air inlet 1305 and the exhaust port of the negative pressure device 140 can be directly connected or indirectly connected. For example, the air inlet 1305 and the exhaust port of the negative pressure device 140 can be communicated through an air inlet channel. The air outlet 1306 is communicated with the atmosphere, and the air outlet 1306 can be directly connected to the atmosphere or indirectly connected to the atmosphere, for example, the air outlet 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 of communicating the air inlet 1305 and the driving air port 1307 through the second passage 1332 while the negative pressure device 140 pumps the air in the sewage cavity 121, and the gas pumped out of 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 utility model can drive the pneumatic valve through the negative pressure device 140, without the need to additionally set the negative pressure device 140, other valves or adapters, so as to realize the blocking and conductive of the sewage pipeline 160, simplify the system design, reduce the manufacturing and maintenance cost, and save the internal space of the base station.

[0110] In some embodiments, when the second passage 1332 is communicated with the air inlet 1305 and the air outlet 1306, the negative pressure device 140 extracts the gas in the sewage cavity 121 and discharges it through the air outlet 1306. For example, when the on-off assembly 150 is in the blocking state, the second passage 1332 of the second valve core 133b is communicated with the air inlet 1305 and the air outlet 1306, and the negative pressure device 140 pumps the air in the sewage cavity 121. When the negative pressure value in the sewage cavity 121 reaches the requirement, the second passage 1332 of the second valve core 133b can be controlled to be communicated with the cavity of the pneumatic valve and the air outlet 1306, the gas in the 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 extraction of the sewage cavity 121, the blocking of the sewage pipeline 160 and the conductive 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.

[0111] Please refer to Figure 3 , Figure 5 andFigure 10 In the first embodiment of the cleaning base station of the present application, the first liquid outlet 1304 is in communication with the host water supplement pipeline 171, and the control valve 130 has a host liquid delivery state of communicating the liquid inlet 1301 and the first liquid 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 liquid inlet 1301 is in communication with the first liquid outlet 1304, and the cleaning water in the clean water chamber 110 flows into the host water supplement pipeline 171 under the action of gravity or the clean water pump, thereby providing water supply for the clean water box of the host.

[0112] Please refer to Figure 3 , Figure 5 and Figure 13 In the first embodiment of the cleaning base station of the present application, the first shell 131a further comprises an air vent 1303 in communication with the atmosphere, the air 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 clean water chamber 110. The control valve 130 further has a host water supplement pipeline 171 anti-siphon state of communicating the liquid inlet 1301, the air vent 1303 and the first liquid 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 liquid inlet 1301, the air vent 1303 and the first liquid outlet 1304, the first liquid outlet 1304 can be in communication with the atmosphere, thereby destroying the siphon condition that may be formed, and effectively preventing the siphon effect of the host water supplement pipeline 171 on the clean water chamber 110 when the liquid delivery is stopped.

[0113] In the first embodiment of the cleaning base station of the present application, the control valve 130 further has a cleaning liquid delivery state of communicating the liquid inlet 1301 and the second liquid 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 control valve 130 can be used to communicate the liquid inlet 1301 and the second liquid outlet 1302, so that the cleaning water in the clean water chamber 110 can flow into the cleaning pipeline 172 under the action of gravity or the clean water pump, thereby providing cleaning water supply for cleaning the cleaning parts of the host.

[0114] It should be noted that in other embodiments, the liquid delivery pipeline 170 can only include the host water supplement pipeline 171 or the cleaning pipeline 172, so that the corresponding control valve 130 can only have the first liquid outlet 1304 or the second liquid outlet 1302. When the liquid delivery pipeline 170 includes the host water supplement pipeline 171 and the cleaning pipeline 172, the corresponding control valve 130 has the first liquid outlet 1304 and the second liquid outlet 1302.

[0115] 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 not only the host liquid conveying state of communicating the first liquid outlet 1304 with the first liquid inlet 1301 through the first channel 1331, but also 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 one of 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. In this way, the cleaning base station can have more function integration, and the control of multiple liquid conveying pipelines 170 can be integrated through the same control valve 130, thereby saving costs and simplifying the installation process of the water pipeline.

[0116] 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 also has the cleaning liquid conveying pipeline 170 anti-siphon state of simultaneously communicating the first liquid inlet 1301 with the vent 1303 and the second liquid outlet 1302 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 first liquid inlet 1301 with the vent 1303 and the second liquid outlet 1302, 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.

[0117] It should be noted that in the present utility model, 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 not only the host water supplement pipeline 171 anti-siphon state of simultaneously communicating the first liquid inlet 1301 with the vent 1303 and the first liquid outlet 1304 through the first channel 1331, but also the cleaning liquid conveying pipeline 170 anti-siphon state of simultaneously communicating the first liquid inlet 1301 with the vent 1303 and the second liquid outlet 1302 through the first channel 1331.

[0118] Along the rotation direction of the first valve core 133a, the air vent 1303 is arranged between the first liquid outlet 1304 and the second liquid outlet 1302, when the host machine infusion is completed, the first valve core 133a is rotated to directly switch from the host machine infusion state to the host machine water supplement pipeline 171 anti-siphon state, when the infusion of the cleaning tank 180 is completed, the first valve core 133a is reversely rotated to directly switch from the cleaning infusion state to the cleaning infusion pipeline 170 anti-siphon state. The setting can make the cleaning base station have more function integration, and can integrate the control of the plurality of infusion pipelines 170 through the same control valve 130, can save the cost, and simplify the installation process of the water circuit.

[0119] The cleaning base station of the utility model can not have the cleaning liquid adding function, and the adding of the cleaning liquid is realized by manual operation, preferably, in an embodiment of the cleaning base station of the utility model, the cleaning base station further comprises a cleaning liquid extraction device 190, and the cleaning liquid extraction device 190 is installed on the base station main body 100. The cleaning liquid extraction device extracts the cleaning liquid from the cleaning liquid outlet 1309 and adds the cleaning liquid into the host machine water supplement pipeline 171 or the cleaning pipeline 172.

[0120] In an embodiment of the cleaning base station of the utility model, the cleaning base station further comprises a plurality of cleaning liquid pipelines, the control valve 130 further comprises a third valve section 130c, the third valve section 130c comprises a third valve core 133c, and when the third valve core 133c moves, any one of the plurality of cleaning liquid pipelines is switched to be communicated with the host machine water supplement pipeline 171 or the cleaning pipeline 172. When the control valve 130 further comprises the first valve core 133a, the first valve core 133a and the third valve core 133c move synchronously. When the control valve 130 further comprises the second valve core 133b, the second valve core 133b and the third valve core 133c move synchronously. When the control valve 130 further comprises the first valve core 133a and the second valve core 133b, the first valve core 133a, the second valve core 133b and the third valve core 133c move synchronously. The synchronous movement part can refer to the above-mentioned embodiment, and details are not described herein. The switching control of the cleaning water circuit is realized through the first valve section 130a, the opening and closing control of the sewage pipeline 160 is realized through the second valve section 130b, and the adding control of the cleaning liquid is realized through the third valve section 130c, so that a plurality of control valves 130 doors are not needed, the installation circuit can be simplified, and the base station space is saved.

[0121] In the utility model cleaning base station one embodiment, third valve section 130c can include third casing 131c, third casing 131c includes cleaning liquid outlet 1309 and multiple cleaning liquid inlets 1308, multiple cleaning liquid inlets 1308 are communicated different cleaning liquid pipeline respectively, third valve core 133c includes third passage 1333, when third passage 1333 is communicated with cleaning liquid outlet 1309 and any cleaning liquid inlet 1308, cleaning liquid inlet 1308 corresponding cleaning liquid pipeline is communicated with host water supply pipeline 171 or cleaning pipeline 172. The liquid flow passageway (such as cleaning liquid outlet 1309, multiple cleaning liquid inlets 1308) is arranged on the casing, the passage is arranged on the valve core 133, by switching the communication of the passage and different liquid flow passageway, the switching of multiple cleaning liquid can be realized, and the structure is more simple and compact. Further, on the basis of the structure, the communication of the passage and different liquid flow passageway is realized by rotating the control valve 130 core relative to the casing, and the simplicity of the structure setting such as driving and position detection can also be reduced.

[0122] Cleaning liquid outlet 1309 can be communicated between only water cavity 110 or liquid inlet 1301 by cleaning liquid adding pipeline 102, and can also be communicated between water cavity 110 and liquid inlet 1301 by cleaning liquid adding pipeline 102 simultaneously, cleaning liquid inlet 1308 is communicated with cleaning liquid storage cavity, and the cleaning liquid storage cavity can be arranged on base station main body 100, or can be the inner cavity of cleaning agent storage bottle directly.

[0123] First valve core 133a, second valve core 133b and third valve core 133c can also be connected in other ways, and the connection mode of first valve core 133a and second valve core 133b can be referred to above, which will not be repeated here. In the utility model cleaning base station one embodiment, at least two of first valve core 133a, second valve core 133b and third valve core 133c are integrally formed to form an integral valve core 133. For example, any two of first valve core 133a, second valve core 133b and third valve core 133c can be integrally formed, or first valve core 133a, second valve core 133b and third valve core 133c can be integrated on one valve core 133. Specifically, in the embodiment, first valve core 133a, second valve core 133b and third valve core 133c are integrated on one valve core 133 and integrally formed, so that no additional parts are needed to install, which can improve the assembly efficiency and installation precision.

[0124] The relative positions among 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 pipeline in the base station. For example, when the first valve core 133a, the second valve core 133b and the third valve core 133c are integrally formed and coaxially rotate, the first valve core 133a, the second valve core 133b and the third valve core 133c can be sequentially distributed along the axial direction of the valve core. Figure 2 and Figure 5 As shown in the figures, 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 can be arranged in the middle, and the third valve core 133c can be arranged at the lowermost end. Of course, the figures are only preferred examples, and 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.

[0125] 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, in order to facilitate assembly, the first shell 131a and the second shell 131b are integrally formed, and the third shell 131c is detachably connected to the second shell 131b.

[0126] 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 a 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 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.

[0127] If different cleaning scenarios are not considered, the cleaning base station can be provided with only one cleaning liquid storage cavity, and only one corresponding cleaning liquid inlet 1308 can be provided, or two cleaning liquid storage cavities can be provided, and two corresponding cleaning liquid inlets 1308 are provided, 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 provided in sequence, and more cleaning liquid inlets 1308 are provided in correspondence.

[0128] In an embodiment, the cleaning operation of the host has multiple different scenarios, and different cleaning liquids need to be used for different scenarios. Therefore, the cleaning base station includes multiple cleaning liquid storage cavities for storing different cleaning liquids. Different cleaning liquids are used for different cleaning scenarios, for example, when the host cleans hard floors, bathrooms, kitchens, or other different room areas or different dirty areas, different cleaning liquids can be supplied to the host 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, and the number of the multiple cleaning liquid inlets 1308 is equal to the number of the multiple cleaning liquid storage cavities, and they are respectively in communication. Of course, different cleaning liquids can also be added for the cleaning of the host. For example, different cleaning liquids can be used to clean the cleaning part after cleaning different room areas or different dirty areas of the host, such as adding a deodorant to the cleaning part to remove the odor on the cleaning part after cleaning the feces area, and so on.

[0129] In an embodiment, the third housing 131c can include seven cleaning liquid inlets 1308, and each cleaning liquid inlet 1308 is 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 a cleaning liquid inlet interface 13331 and a cleaning liquid outlet interface 13332, respectively. The cleaning liquid inlet interface 13331 is arranged on the circumferential wall 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 to different cleaning liquid inlets 1308, so that the third channel 1333 sequentially connects the cleaning liquid outlet 1309 to different cleaning liquid inlets 1308.

[0130] By the design of the plurality of cleaning liquid storage cavities and the plurality of 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 types of cleaning liquids to cope with various cleaning scenarios and needs, improving the applicability and flexibility of the cleaning base station. At the same time, the control valve 130 can not only switch the cleaning water supply by integrating the first valve segment 130a, the second valve segment 130b, and the third valve segment 130c in one valve core 133, but also switch the sewage pipeline 160 on and off, and can also switch the cleaning liquid supply to the host water supply pipeline and the cleaning pipeline respectively, or switch the different types of cleaning liquid supply to the host water supply pipeline / cleaning pipeline. The cleaning liquid can be quickly switched according to the needs during the cleaning process, further improving the timeliness and convenience of cleaning liquid addition.

[0131] The following is an example of adding multiple cleaning liquids to the host water supply pipeline.

[0132] 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, and the liquid storage groove 1323 is partially arranged around the outer periphery of the first valve core 133a. 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 maintaining of the communication between the first channel 1331 and the liquid storage groove 1323, the third valve core 133c makes the cleaning liquid outlet 1309 sequentially communicate with at least two cleaning liquid inlets 1308 corresponding to the host water supply pipeline.

[0133] 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 shell during the rotation of the valve core 133. 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 rotates 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 also rotates by a corresponding angle. At least two different cleaning liquid inlets 1308 corresponding to the host water supplement pipeline are arranged on the shell 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 supplement pipeline 171.

[0134] In the scenario where multiple cleaning liquids need to be added to the host water supplement pipeline 171, this design avoids frequent replacement of cleaning liquids or the arrangement of multiple independent adding devices, greatly improves the flexibility and diversity of cleaning liquid addition, and meets different cleaning needs. 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.

[0135] In the scenario where multiple cleaning liquids are added to the cleaning pipeline, reference can be made to the above description. Correspondingly, the second liquid outlet 1304 is in communication with the liquid storage groove 1323, and other structures are also adjusted flexibly, which will not be described herein.

[0136] Please refer to Figure 19 In an embodiment of the utility model, the shell includes seven cleaning liquid inlets 1308. 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 third channel 1333 makes the cleaning liquid outlet 1309 sequentially communicate with the six cleaning liquid inlets 1308. In this way, six different cleaning liquids can be added to the host water supplement pipeline 171 in one rotation period of the valve core 133, which can meet more cleaning needs of the host. The other cleaning liquid inlet 1308 corresponds to the cleaning pipeline, so that the cleaning liquid can be supplemented to the host water supplement pipeline and the cleaning pipeline at the same time. Of course, if the cleaning pipeline also needs to be supplemented with multiple cleaning liquids, the above-mentioned embodiment can also be implemented, which will not be described herein.

[0137] 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 in the utility model. Preferably, in the cleaning base station embodiment of the utility model, the cleaning liquid extraction device 190 is arranged on the cleaning liquid adding pipeline 102.

[0138] In the cleaning base station embodiment of the utility model, the cleaning liquid extraction device 190 is a peristaltic pump. The peristaltic pump has a unique extrusion conveying principle, the cleaning liquid is pushed forward in the pipeline through the rolling extrusion of the pump head, the efficient and stable extraction of the cleaning liquid can be realized, even in the case that the cleaning liquid viscosity is high or there is a certain resistance in the pipeline, the good extraction effect can also be maintained, the smooth delivery of the cleaning liquid is ensured, and the cleaning base station is provided with continuous and stable cleaning liquid supply. Moreover, the structure of the peristaltic pump is relatively simple, the key component, the hose, is directly contacted with the cleaning liquid in the use process, and other components such as the pump head are not directly contacted with the cleaning liquid, which makes the peristaltic pump more convenient to maintain and clean, only the hose needs to be replaced regularly, the maintenance cost and difficulty are reduced, and the health and cleanliness of the cleaning liquid extraction device 190 are also maintained, so that the cleaning effect of the cleaning liquid is not affected by the pollution inside the device.

[0139] In the utility model, the scale can be arranged on the shell, the pointer can be arranged on the valve core 133, and the position of the valve core 133 relative to the shell can be determined through the relationship between the pointer and the scale. Preferably, considering the demand for automation, in the cleaning base station embodiment of the utility model, 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 arranged 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 that the rotation angle and position of the valve core 133 can be accurately controlled, which is very important for the operations such as the switching of multiple cleaning liquids, the conversion of different cleaning modes and the accurate control of the position of the valve core 130 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 that the cleaning base station can accurately perform various actions according to the preset program and requirements, and the control accuracy and reliability of the cleaning base station are improved.

Meanwhile, the split type installation mode of the detection element 13131 and the sensing piece 13132 makes it possible to respectively install the detection element 13131 at a suitable position of the shell and install the sensing piece 13132 on the valve core 133 during the assembly process of the cleaning base station, and the installation process is relatively simple and convenient.

After the magnetic piece as the sensing piece 13132 is fixedly connected with the valve core 133, the change of the magnetic field will occur during the rotation of the valve core 133, and 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 also be accurately captured, thereby providing technical support for the fine control of the cleaning base station.

[0142] In the utility model, the installation mode of the detection element 13131 on the shell can be various, for example, the detection element 13131 can be clamped to the shell or directly fixed to the shell through a bolt assembly, but is not limited thereto.
