Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other. It should also be understood that the terminology used in the embodiments of the present invention is for describing specific implementation schemes and not for limiting the scope of protection of the present invention. Test methods in the following embodiments that do not specify specific conditions are generally performed under conventional conditions or according to the conditions recommended by the respective manufacturers.

[0075] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise stated in the present invention, both endpoints of each numerical range and any value between the two endpoints may be selected. Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, devices, and materials similar to or equivalent to those described, used, or made of materials in the embodiments of this invention.

[0076] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as part of the scope of the invention.

[0077] Please refer to Figures 1 to 27. The present invention provides a cleaning system, which may include a cleaning base station and a host. The host may be a robot vacuum cleaner, etc. The cleaning base station may be used to realize one or more functions such as charging the robot vacuum cleaner, cleaning the cleaning components, and garbage collection.

[0078] Please refer to Figures 1 to 3. The clean base station includes a base station body 100 and a sewage chamber 121, a clean water chamber 110, a clean water pump (not shown), a negative pressure device 140, an infusion pipeline 170, a sewage pipeline 160, and a control valve 130 disposed on the base station body 100.

[0079] The shape of the base station body 100 is not limited. For example, it can be roughly rectangular in shape as a whole, or the lower part can be rectangular in shape and the top part can be spherical. However, it is not a limitation. Considering the needs of indoor placement, it is best to be aesthetically pleasing and small in size.

[0080] The shape and structure of the sewage chamber 121 are not limited. For example, it can be directly installed on the base station body 100, or a detachable sewage tank 120 can be installed on the base station body 100, with the sewage chamber 121 being the accommodating space formed within the sewage tank 120. The structure and wall thickness of the sewage chamber 121 are suitable for manufacturing and have sufficient strength to prevent deformation when the negative pressure is pumped to a set threshold. One end of the sewage pipe 160 is connected to the highest liquid level in the sewage chamber 121, and the other end of the sewage pipe 160 is connected to the liquid to be pumped. The diameter of the sewage pipe 160 can be referenced to the diameter of the sewage pipe 160 on existing base stations. In some embodiments, the minimum inner diameter of the sewage pipe 160 is greater than 18 mm and less than 25 mm.

[0081] The negative pressure device 140 can perform a vacuuming operation on the sewage chamber 121 to reduce the air pressure inside the sewage chamber 121. Based on the pressure difference, sewage enters the sewage chamber 121 through the sewage pipe 160. The negative pressure device 140 can be any suitable device capable of suctioning gas, such as a vacuum pump, centrifugal fan, axial flow fan, plunger pump, etc., but is not limited thereto. The connection method between the air extraction port of the negative pressure device 140 and the sewage chamber 121 is not limited. For example, an air extraction hole can be formed by opening a hole in the wall above the highest liquid level of the sewage chamber 121, and the air extraction port of the negative pressure device 140 can be directly connected to the air extraction hole. Alternatively, the air extraction port of the negative pressure device 140 can be indirectly connected to the air extraction hole through a pipe. Specifically, in this embodiment, the air extraction port of the negative pressure device 140 is connected to the sewage chamber 121 through an air extraction pipe 103. One end of the air extraction pipe 103 is connected to the air extraction port of the negative pressure device 140, and the other end of the air extraction pipe 103 is connected to the wall of the chamber above the highest liquid level of the sewage chamber 121.

[0082] The base station body 100 may include a receiving cavity located at the bottom of the base station body 100 and having an opening for the host to enter. The receiving cavity may also be provided with a charging terminal that can be electrically connected to a charging device to charge the host. However, it should be noted that if charging is not considered, the base station body 100 of the present invention may not be provided with a charging terminal.

[0083] In some embodiments, the cleaning base station may further include a cleaning tank 180 for cleaning the cleaning components of the host, the cleaning tank 180 being formed in a receiving cavity. One end of a wastewater pipe 160 is connected to the highest liquid level of the wastewater chamber 121, and the other end of the wastewater pipe 160 is connected to the cleaning tank 180. A funnel-shaped suction port may be provided in the cleaning tank, located at the lowest point of the cleaning tank 180, and the other end of the wastewater pipe 160 may be connected to this suction port.

[0084] However, it should be noted that in other embodiments, the cleaning tank 180 may not be provided. For example, the host may be equipped with a wastewater box. During the host cleaning process, the cleaning components can be cleaned, and the wastewater after cleaning is collected in the wastewater box. When the host is connected to the base station, the wastewater box can be connected to the wastewater pipe 160, and the wastewater pipe 160 can extract the wastewater from the wastewater box on the host. For example, when the host enters the cleaning base station and completes positioning, one end of the wastewater pipe 160 is connected to the top of the wastewater chamber 121, and the other end of the wastewater pipe 160 is connected to the bottom of the wastewater box on the host, thereby realizing the extraction of wastewater from the host.

[0085] In some embodiments, the base station body 100 may also be provided with a switching component 150. The switching component 150 is disposed on the sewage pipe 160 and has a blocking state that blocks the sewage pipe 160 and a conducting state that allows the sewage pipe 160 to conduct. The switching component 150 can be a pneumatic valve or a hydraulic valve. For example, a pneumatic valve has an air chamber and a flexible compression part. The air chamber is located outside the flexible compression part. When the gas in the air chamber increases, the gas causes the flexible compression part to compress and block the water flow in the sewage pipe 160. When the gas in the air chamber decreases, the flexible compression part recovers its deformation in the direction away from the sewage pipe, and the sewage pipe 160 becomes conductive. For example, the sewage pipe 160 has a flexible structure, and the flexible compression part can be located outside the sewage pipe 160. When the gas in the air chamber increases, the flexible compression part protrudes towards the sewage pipe 160, compressing and blocking the water flow in the sewage pipe 160. After the gas in the air chamber decreases, the flexible extrusion section returns to its original shape, moving away from the sewage pipe, and the sewage pipe 160 becomes open. Alternatively, the sewage pipe 160 consists of two sections, with a pneumatic valve located between them. When the gas in the air chamber increases, the gas causes the flexible extrusion section to bulge inward, compressing and blocking the water flow in the sewage pipe 160. After the gas in the air chamber decreases, the flexible extrusion section returns to its original shape, and the sewage pipe 160 becomes open.

[0086] When the on / off component 150 is in the blocked state, the sewage chamber 121 can be evacuated so that when the on / off component 150 is switched to the open state, the sewage pipeline 160 can be pumped out by the negative pressure in the sewage chamber 121.

[0087] For example, when the on / off component 150 is switched to the blocking state, the negative pressure device 140 can perform a vacuuming operation on the sewage chamber 121 to bring the negative pressure in the sewage chamber 121 to a set threshold. While the negative pressure in the sewage chamber 121 remains at the set threshold, the on / off component 150 is switched to the conducting state, and the sewage in the cleaning tank 180 is drawn into the sewage chamber 121 from the sewage pipe 160 under the action of the negative pressure in the sewage chamber 121. It should be noted that the set threshold can be calculated based on the volume of the liquid to be pumped, the diameter of the sewage pipe 160, and the pumping distance, or it can be obtained experimentally. For example, a negative pressure threshold can be set in the sewage chamber 121 to pump all the sewage in the cleaning tank 180 into the sewage chamber 121 at once. Considering the diameter of the sewage pipe 160 of the existing cleaning base station, the distance from the sewage chamber 121 to the cleaning tank 180, and the volume of the cleaning tank 180, the set threshold can be 30 kPa. It should also be noted that, considering the existence of error, slight fluctuations above and below the set threshold are considered "maintaining" the value, with slight fluctuations referring to ±10 kPa.

[0088] By setting up the on / off component 150 corresponding to the sewage pipe 160, the sewage pipe 160 can be cut off, creating a sealed space inside the sewage chamber 121. Under the action of the negative pressure device 140, a large negative pressure can be generated in the sewage chamber 121, effectively increasing the sewage extraction speed and reducing the time required for sewage extraction. Simultaneously, it reduces the mixing of gas and sewage, thereby reducing bubbling noise. Furthermore, compared to a suction operation that simultaneously extracts air and sewage, it achieves greater suction force, increasing the carrying rate of deposited impurities in the cleaning tank 180, reducing dirt deposition at the bottom of the cleaning tank 180, and further facilitating maintenance-free operation of the cleaning tank 180.

[0089] The shape and structure of the clean water chamber 110 are not limited and can refer to existing structures. The clean water chamber 110 is used to hold cleaning water to provide cleaning water supply for the host to clean the ground, and / or to provide cleaning water supply for cleaning the cleaning components of the host. The base station body 100 can be provided with a host water supply pipe 171 and a cleaning pipe 172. The host water supply pipe 171 can connect the clean water chamber 110 and the clean water box of the host, and the cleaning pipe 172 can connect the clean water chamber 110 and the cleaning tank 180. If the base station body 100 is provided with a host water supply port (not shown) for replenishing water to the host and a cleaning spray port (not shown) for providing cleaning water during the cleaning of the cleaning components of the host, the host water supply pipe 171 connects the clean water chamber 110 and the host water supply port, and the cleaning pipe 172 connects the clean water chamber 110 and the cleaning spray port. The wastewater generated after cleaning the cleaning components can enter the wastewater pipe 160 through the suction port of the cleaning tank 180, and then enter the wastewater chamber 121.

[0090] The infusion line 170 can be a main unit water supply line 171 or a cleaning line 172. Alternatively, the infusion line 170 can include both the main unit water supply line 171 and the cleaning line 172.

[0091] The control valve 130 is mounted on the base station body 100, and the mounting method is not limited. In some embodiments, the control valve 130 can be detachably connected to the base station body 100 for easy maintenance.

[0092] When a sewage pipe 160, a host water supply pipe 171, a cleaning pipe 172, a sewage chamber 121, and a clean water chamber 110 are provided on the base station body 100, and an on / off component 150 is provided on the sewage pipe 160, the control valve 130 may include a first valve section 130a and a second valve section 130b. The first valve section 130a includes a first valve core 133a, and the second valve section 130b includes a second valve core 133b. When the first valve core 133a moves, it switches the clean water chamber 110 to connect with either the host water supply pipe 171 or the cleaning pipe 172. When the second valve core 133b moves, it switches the on / off component 150 to either a blocking state or a conducting state. The first valve core 133a and the second valve core 133b move synchronously. By controlling the synchronous movement of two valve cores to switch the clean water circuit and open / close the sewage pipe 160, the drive structure and / or control structure of the control valve 130 can be further simplified, the integration of valves within the base station can be improved, and base station space can be saved. For example, the position detection and drive of the two valve cores can be achieved by sharing a set of position detection elements 13131 and / or a set of drive devices 134.

[0093] When using two sets of drive devices 134 to control the movement of the first valve core 133a and the second valve core 133b, the same magnetic component can be connected to both valve cores 133a and 133b, and a Hall sensor can be used to detect the movement in conjunction with this magnetic component. Because the first valve core 133a and the second valve core 133b move synchronously, their rotation angles or movement lengths are the same, resulting in identical signals detected by the Hall sensor. This signal can then be used to simultaneously switch the clean water circuit and open / close the sewage pipe 160. For example, when the first valve core 133a and the second valve core 133b move by rotation, the aforementioned set of detection elements 13131 can detect the rotation angle of the two valve cores, thereby achieving synchronous detection of switching the clean water circuit and opening / closing the sewage pipe 160. This reduces the number of detection elements 13131 and saves base station space.

[0094] Alternatively, the same set of drive devices 134 can be used to control the synchronous movement of the first valve core 133a and the second valve core 133b, reducing the number of drive devices 134 and saving base station space. In this embodiment, the same set of detection elements 13131 can be used to detect the movement position 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 position of the first valve core 133a and the second valve core 133b.

[0095] The first valve core 133a and the second valve core 133b can be connected to form a single valve core 133. This connection facilitates synchronized movement of the two valve cores and increases their integration. The first valve core 133a and the second valve core 133b can be connected in a detachable or fixed manner. Alternatively, they can be integrally molded. This integral design integrates the two valve cores, which previously required separate machining and assembly, into a single unit, reducing the number of parts and assembly steps. Furthermore, the integral molding of the first valve core 133a and the second valve core 133b makes it easier to control their synchronized movement, preventing movement deviations and ensuring control accuracy.

[0096] The control valve 130 may also include a housing. The structure and shape of the housing are not limited. Specifically, classified according to 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, 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 of the first valve core 133a within the first housing 131a and the movement of the second valve core 133b within the second housing 131b can be rotational or linear movement.

[0097] In some embodiments, the first valve core 133a is installed within the first housing 131a, and the second valve core 133b is rotatably installed within 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 connection between the clean water chamber 110 and either the main unit's water supply pipe 171 or the cleaning pipe 172. During the rotation of the second valve core 133b relative to the second housing 131b, the second valve segment 130b switches the sewage pipe 160 between a blocked state and a connected state. Switching the connection state by rotation has relatively less fluid resistance compared to switching states by linear movement, and offers higher responsiveness and accuracy. Furthermore, given the limited space within the base station, controlling the rotation of the valve core 130 avoids additional space occupation, resulting in higher base station integration.

[0098] In one embodiment of the clean base station, the first valve section 130a includes a first housing 131a and a first valve core 133a installed within the first housing 131a. A first channel 1331 is provided within the first valve core 133a. The first housing 131a has an inlet 1301, a first outlet 1304 connected to the main unit's water supply pipe 171, and a second outlet 1302 connected to the cleaning pipe 172. When the first channel 1331 is connected to the inlet 1301 and the first outlet 1304, the clean water chamber 110 is connected to the main unit's water supply pipe 171. When the first channel 1331 is connected to the inlet 1301 and the second outlet 1302, the clean water chamber 110 is connected to the cleaning pipe 172. The inlet 1301 is connected to the clean water chamber 110. For example, a clean water pump can be installed on the base station body 100. The clean water pump is located on the connecting pipe between the clean water chamber 110 and the liquid inlet 1301, providing power for clean water to enter the liquid inlet 1301.

[0099] Liquid flow ports (such as inlet 1301, first outlet 1304, and second outlet 1302) are provided on the housing, and channels are provided on the corresponding valve cores. By switching the channels to connect with different liquid flow ports, the main unit water supply pipeline 171 and cleaning pipeline 172 can be switched, resulting in a simpler and more compact structure. Furthermore, based on this structure, the control valve 130 core rotates relative to the housing to achieve the connection between the channels and different liquid flow ports, which can also simplify the setting of drive and position detection structures.

[0100] In one embodiment of the clean base station, the switching component 150 can be a pneumatic valve, and the base station body 100 is provided with an air inlet channel and an exhaust channel 101. When the pneumatic valve is connected to the air inlet channel, gas enters the air chamber through the air inlet channel. When the pneumatic valve is connected to the exhaust channel 101, gas flows out of the air chamber through the exhaust channel 101. The second valve section 130b switches the pneumatic valve to be connected to either the air inlet channel or the exhaust channel 101. By switching the connection state of the pneumatic valve with the air inlet channel or the exhaust channel 101, the entry or exit of gas from the pneumatic valve can be achieved. The pneumatic valve has high sealing performance and reliability. Using the pneumatic valve as the switching component 150 can improve the sealing performance and reliability of the sewage pipeline blocking and opening.

[0101] In some embodiments, the negative pressure device 140 is connected to the air intake channel. The negative pressure device 140 extracts gas from the sewage chamber 121 and delivers it to the air intake channel so that the gas enters the air chamber. This configuration requires only one negative pressure device 140 and one pneumatic valve, which can both perform air extraction operations on the sewage chamber 121 and achieve the blocking and opening of the sewage pipe, further saving internal space of the base station. In addition, by using the gas extracted from the sewage chamber 121 to drive the pneumatic valve, negative pressure can be simultaneously drawn into the sewage chamber 121 when the sewage pipe is blocked, saving the time of continuing to draw negative pressure into the sewage chamber 121 after the sewage pipe is blocked. Moreover, the pneumatic valve requires less gas, and the initial negative pressure drawn into the sewage chamber 121 will not cause sewage to enter the sewage pipe, or only a small amount of sewage will enter the sewage pipe, so it will not have a significant impact on blocking the sewage pipe.

[0102] Of course, the air intake channel in this invention can also be connected to other air pumps configured elsewhere, as long as gas can enter the air chamber and the sewage pipe 160 can be switched between the blocked state and the open state.

[0103] In one embodiment of the clean base station, the exhaust channel 101 is connected to the atmosphere, allowing gas to be discharged from the gas chamber into the atmosphere. This directly discharges the gas from the pneumatic valve into the atmosphere, eliminating the need for additional piping and further saving internal space in the base station. However, in this invention, the gas from the pneumatic valve can also flow back into the sewage chamber 121 through a separate pipe. If the gas from the pneumatic valve originates from the sewage chamber 121, discharging it back into the atmosphere would introduce odorous gas into the atmosphere, negatively impacting the user experience.

[0104] In one embodiment of the clean base station, the second valve section 130b includes a second housing 131b, and a second valve core 133b is installed inside the second housing 131b. A second channel 1332 is provided inside the second valve core 133b. The second housing 131b has a drive air port 1307, an air inlet 1305, and an air outlet 1306. The air inlet 1305 communicates with the air intake channel, and the air outlet 1306 communicates with the exhaust channel 101. The drive air port 1307 communicates with the air chamber of the pneumatic valve. When the second channel 1332 communicates with the drive air port 1307 and the air inlet 1305, the pneumatic valve communicates with the air intake channel. When the second channel 1332 communicates with the drive air port 1307 and the air outlet 1306, the pneumatic valve communicates with the exhaust channel 101.

[0105] Gas flow ports (such as drive port 1307, inlet port 1305, and outlet port 1306) are provided on the housing, and channels are provided on the corresponding valve cores. By switching the connection between the channels and different gas flow ports, the opening and closing of the sewage pipeline 160 can be realized, making the structure simpler and more compact. Furthermore, based on this structure, the control valve 130 core rotates relative to the housing to realize the connection between the channels and different gas flow ports, which can also simplify the setting of drive and position detection structures.

[0106] In some embodiments, the first valve core 133a is rotatably mounted within the first housing 131a, and the second valve core 133b is rotatably mounted within the second housing 131b. The first valve core 133a and the second valve core 133b rotate to different angles, corresponding to different liquid and gas flow ports. Referring to Figure 21, the first valve core 133a includes a first channel 1331, and the second valve core 133b includes a second channel 1332. During the rotation of the first valve core 133a relative to the first housing 131a and the rotation of the second valve core 133b relative to the second housing 131b, the channels of the valve core 133 of the control valve 130 switch their connection relationships with the liquid flow ports (refer to Figures 10 and 11) and gas flow ports on the housing (refer to Figure 16). By setting the control valve 130 as described above, the control of clean water replenishment and sewage extraction can be achieved, resulting in higher integration of the valve's structure, drive, and control, and saving base station space.

[0107] Please refer to Figures 3 and 17. In one embodiment of the clean base station of the present invention, the on / off component 150 includes a pneumatic valve installed on the sewage pipe 160. The second housing 131b also includes a drive air port 1307. The drive gas inlet of the pneumatic valve is connected to the drive air port 1307. The drive gas inlet and the drive air port 1307 can be directly connected or indirectly connected. In this embodiment, the drive gas inlet can be connected to the drive air port 1307 through the drive pipe 104.

[0108] During the rotation of the valve core 133 relative to the housing, the control valve 130 also has a valve driving state that blocks the air inlet 1305 and the air outlet 1306, and connects the air inlet 1305 and the drive air outlet 1307 through the second channel 1332.

[0109] The pneumatic clamp valve can release air by providing a separate pressure relief port, thereby opening the sewage pipeline 160. Preferably, in one embodiment of the clean base station of the present invention, the pressure relief port on the pneumatic valve and the driving gas inlet are the same interface. Referring to Figure 18, during the rotation of the second valve core 133b relative to the second housing 131b, the control valve 130 also has a valve exhaust state in which the air outlet 1306 and the driving air port 1307 are connected through the second channel 1332. In the valve exhaust state, the gas in the air chamber of the pneumatic valve is discharged from the air chamber, the pneumatic valve switches to the conducting state, and the sewage pipeline 160 can be used for sewage pumping.

[0110] In some embodiments, the air inlet 1305 is connected to 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 or indirectly connected. For example, the air inlet 1305 and the exhaust port of the negative pressure device 140 can be connected through an air inlet channel. The air outlet 1306 is connected to the atmosphere. The air outlet 1306 can be directly connected to the atmosphere or indirectly connected to the atmosphere; for example, the air outlet 1306 is connected to the atmosphere through an exhaust channel 101. This configuration allows the control valve 130 to be switched to a valve-driven state, connecting the air inlet 1305 and the drive air port 1307 via the second channel 1332, while the negative pressure device 140 is drawing air from the sewage chamber 121. The gas drawn from the sewage chamber 121 by the negative pressure device 140 can drive the pneumatic valve to actuate, thereby blocking the sewage pipeline 160. Therefore, the control valve 130 of the present invention can drive the pneumatic valve through the negative pressure device 140, without the need for additional negative pressure device 140, other valves or adapters, to achieve the blocking and opening of the sewage pipeline 160, simplifying system design, reducing manufacturing and maintenance costs, and saving internal space of the base station.

[0111] In some embodiments, when the second channel 1332 is connected to the air inlet 1305 and the air outlet 1306, the negative pressure device 140 extracts gas from the sewage chamber 121 and discharges it through the air outlet 1306. For example, when the on / off assembly 150 is in the blocked state, the second channel 1332 of the second valve core 133b is connected to the air inlet 1305 and the air outlet 1306, and the negative pressure device 140 performs a evacuation operation on the sewage chamber 121. When the negative pressure value in the sewage chamber 121 reaches the required level, the second channel 1332 of the second valve core 133b can be connected to the air chamber of the pneumatic valve and the air outlet 1306, the gas in the air chamber of the pneumatic valve is discharged, the pneumatic valve switches to the conducting state, the sewage pipeline 160 is opened, and based on the negative pressure in the sewage chamber 121, the sewage in the cleaning tank 180 enters the sewage chamber 121 through the sewage pipeline 160. This configuration allows for the control of negative pressure in the sewage chamber 121, blocking of the sewage pipe 160, and opening of the sewage pipe 160 through the same control valve 130. This significantly reduces the number of components in the control valve 130, simplifies the overall structure, and thus lowers production costs.

[0112] Please refer to Figures 3, 5, and 10. In one embodiment of the clean base station of the present invention, the first liquid outlet 1304 is connected to the host water supply pipeline 171. During the rotation of the first valve core 133a relative to the first housing 131a, the control valve 130 has a host liquid supply state in which the inlet 1301 and the first liquid outlet 1304 are connected through the first channel 1331. In this state, the inlet 1301 and the first liquid outlet 1304 are connected, and the clean water in the clean water chamber 110 flows into the host water supply pipeline 171 under the action of gravity or a clean water pump, thereby providing water supply to the host's clean water box.

[0113] Please refer to Figures 3, 5, and 13. In one embodiment of the clean base station of the present invention, the first housing 131a further includes a vent 1303 communicating with the atmosphere. The vent 1303 is connected to the atmosphere through an exhaust channel 101. The exhaust channel 101 is located above the highest liquid level in the clean water chamber 110. During the rotation of the first valve core 133a relative to the first housing 131a, the control valve 130 also has an anti-siphon state for the main unit water supply pipeline 171, which connects the liquid inlet 1301 to the vent 1303 and the first liquid outlet 1304 through the first channel 1331. By rotating the first valve core 133a to connect the liquid inlet 1301 to the vent 1303 and the first liquid outlet 1304, the first liquid outlet 1304 can be connected to the atmosphere, thereby destroying the possible siphon conditions and effectively preventing the main unit water supply pipeline 171 from siphoning the clean water chamber 110 when the liquid supply stops.

[0114] In one embodiment of the cleaning base station of the present invention, during the rotation of the first valve core 133a relative to the first housing 131a, the control valve 130 also has a cleaning fluid delivery state that connects the inlet 1301 and the outlet 1302 through the first channel 1331. When the host enters the cleaning tank 180, the inlet 1301 and the outlet 1302 can be connected by the control valve 130, so that the cleaning water in the clean water chamber 110 can flow into the cleaning pipeline 172 under the action of gravity or a clean water pump, which can provide a clean water supply for cleaning the cleaning components of the host.

[0115] It should be noted that in other embodiments, the infusion line 170 may only include the main unit water supply line 171 or the cleaning line 172. In this case, the corresponding control valve 130 may only have the first outlet 1304 or the second outlet 1302. In the case where the infusion line 170 includes both the main unit water supply line 171 and the cleaning line 172, the corresponding control valve 130 may have both the first outlet 1304 and the second outlet 1302.

[0116] The first outlet 1304 is connected to the main unit's water supply pipeline 171, and the second outlet 1302 is connected to the cleaning pipeline 172. During the rotation of the first valve core 133a relative to the first housing 131a, the control valve 130 has both a main unit infusion state (connecting the inlet 1301 and the first outlet 1304 via the first channel 1331) and a cleaning infusion state (connecting the inlet 1301 and the second outlet 1302 via the first channel 1331). The main unit infusion state and the cleaning infusion state are mutually exclusive; that is, during the rotation of the valve core 133a, only one of the first outlet 1304 and the second outlet 1302 can be connected via the first channel 1331. The main unit infusion state and the cleaning infusion state can also be simultaneously present; that is, during the rotation of the first valve core 133a, the first channel 1331 can be simultaneously connected to both the first outlet 1304 and the second outlet 1302. This setup not only allows for more integrated functions at the cleaning base station, but also enables the integration of control over multiple infusion lines 170 through the same control valve 130, saving costs and simplifying the water line installation process.

[0117] In one embodiment of the clean base station of the present invention, the first housing 131a further includes a vent 1303 communicating with the atmosphere. The vent 1303 is connected to the atmosphere through an exhaust channel 101, and the exhaust channel 101 is located above the highest liquid level in the clean water tank. During the rotation of the first valve core 133a relative to the first housing 131a, the control valve 130 also has an anti-siphon state for the cleaning infusion pipeline 170, which connects the inlet 1301 to the vent 1303 and the second outlet 1302 through the first channel 1331. Similar to the anti-siphon state of the main unit water replenishment pipeline 171, the rotation of the first valve core 133a connects the inlet 1301 to the vent 1303 and the second outlet 1302, making the second outlet 1302 communicate with the atmosphere, thus preventing the siphon effect of the cleaning infusion pipeline 170 on the clean water chamber 110 after cleaning.

[0118] It should be noted that in this invention, the control valve 130 may only include the anti-siphon state of the cleaning infusion pipeline 170 or the anti-siphon state of the main unit water supply pipeline 171. The vent 1303 is connected to the atmosphere through the exhaust channel 101. The position of the exhaust channel 101 connected to the atmosphere is located above the highest liquid level in the clean water tank. During the rotation of the first valve core 133a relative to the housing, the control valve 130 has both the anti-siphon state of the main unit water supply pipeline 171, which connects the inlet 1301 to the vent 1303 and the first outlet 1304 through the first channel 1331, and the anti-siphon state of the cleaning infusion pipeline 170, which connects the inlet 1301 to the vent 1303 and the second outlet 1302 through the first channel 1331.

[0119] Along the rotation direction of the first valve core 133a, the vent 1303 is located between the first liquid outlet 1304 and the second liquid outlet 1302. When the main unit's liquid infusion ends, rotating the first valve core 133a can directly switch from the main unit's liquid infusion state to the anti-siphon state of the main unit's water replenishment pipeline 171. When the liquid infusion to the cleaning tank 180 ends, the first valve core 133a can also be rotated in the opposite direction to directly switch from the cleaning liquid infusion state to the anti-siphon state of the cleaning liquid infusion pipeline 170. This configuration allows the cleaning base station to have more integrated functions, and the control of multiple liquid infusion pipelines 170 can be integrated through the same control valve 130, which can save costs and simplify the water circuit installation process.

[0120] The cleaning base station of the present invention may not have a cleaning fluid addition function, but the cleaning fluid is added manually. Preferably, in one embodiment of the cleaning base station of the present invention, the cleaning base station further includes a cleaning fluid extraction device 190, which is installed on the base station body 100. The cleaning fluid extraction device extracts cleaning fluid from the cleaning fluid outlet 1309 and adds it to the host water supply pipeline 171 or the cleaning pipeline 172.

[0121] In one embodiment of the cleaning base station of the present invention, the cleaning base station further includes multiple cleaning fluid pipelines, and the control valve 130 further includes a third valve section 130c, which includes a third valve core 133c. When the third valve core 133c moves, it switches any one of the multiple cleaning fluid pipelines to connect with the host water supply pipeline 171 or the cleaning pipeline 172. When the control valve 130 also includes a first valve core 133a, the first valve core 133a and the third valve core 133c move synchronously. When the control valve 130 also includes a second valve core 133b, the second valve core 133b and the third valve core 133c move synchronously. When the control valve 130 also includes a first valve core 133a and a 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 be referred to the above embodiment, and will not be repeated here. The switching control of the clean 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 addition control of the cleaning liquid is realized through the third valve section 130c. There is no need to set up multiple control valves 130, which simplifies the installation circuit and saves base station space.

[0122] In one embodiment of the clean base station of the present invention, the third valve section 130c may include a third housing 131c, the third housing 131c including a cleaning fluid outlet 1309 and multiple cleaning fluid inlets 1308, the multiple cleaning fluid inlets 1308 being respectively connected to different cleaning fluid pipelines, and the third valve core 133c including a third channel 1333. When the third channel 1333 is connected to the cleaning fluid outlet 1309 and any cleaning fluid inlet 1308, the cleaning fluid pipeline corresponding to the cleaning fluid inlet 1308 is connected to the host water supply pipeline 171 or the cleaning pipeline 172. By providing liquid flow ports (such as the cleaning fluid outlet 1309 and multiple cleaning fluid inlets 1308) on the housing and providing channels on the valve core 133, the switching of multiple cleaning fluids can be realized by switching the channels to connect to different liquid flow ports, making the structure simpler and more compact. Furthermore, based on this structure, the control valve core 130 rotates relative to the housing to realize the connection between the channels and different liquid flow ports, which can also simplify the setting of drive and position detection structures.

[0123] The cleaning fluid outlet 1309 can be connected to the water chamber 110 or the inlet 1301 via the cleaning fluid addition pipe 102, or it can be connected to both the water chamber 110 and the inlet 1301 via the cleaning fluid addition pipe 102. The cleaning fluid inlet 1308 is connected to the cleaning fluid storage chamber, which can be located on the base station body 100 or directly inside the cleaning fluid storage bottle.

[0124] 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, please refer to the above description of the connection method for the first valve core 133a and the second valve core 133b, which will not be repeated here. In one embodiment of the clean base station of the present invention, 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 onto one valve core 133. Specifically, in this embodiment, the first valve core 133a, the second valve core 133b, and the third valve core 133c are integrated onto one valve core 133 and integrally formed. This eliminates the need for additional component installation, improving assembly efficiency and installation accuracy.

[0125] The relative positions of the first valve core 133a, the second valve core 133b, and the third valve core 133c can be flexibly adjusted according to the arrangement of the pipelines within the base station. For example, if the first valve core 133a, the second valve core 133b, and the third valve core 133c are integrally formed and rotate coaxially, they can be distributed sequentially along the axial direction of the valve cores. As shown in Figures 2 and 5, if the axis of the control valve is the height direction of the base station, the first valve core 133a can be positioned at the top to facilitate the installation of the anti-siphon pipeline, the second valve core 133b in the middle, and the third valve core 133c at the bottom. Of course, the figures are only preferred examples; those skilled in the art can flexibly adjust the axial direction of the valve cores and the distribution positions of each valve core according to the pipeline arrangement.

[0126] In one embodiment of the clean base station of the present invention, at least two of the first housing 131a, the second housing 131b, and the third housing 131c are integrally formed. For example, any two of the first housing 131a, the second housing 131b, and the third housing 131c can be integrally formed, or the first housing 131a, the second housing 131b, and the third housing 131c can be integrally formed. Specifically, in this embodiment, for ease of assembly, the first housing 131a and the second housing 131b are integrally formed, and the third housing 131c is detachably connected to the second housing 131b.

[0127] In some embodiments, the first housing 131a of the control valve 130 is provided with a cleaning fluid inlet 1310, which is connected to the inlet 1301. One end of the cleaning fluid inlet pipe 102 is connected to the cleaning fluid outlet 1309, and the other end of the cleaning fluid inlet pipe 102 is connected to the cleaning fluid inlet 1310. Under the action of the cleaning fluid extraction device 190, the cleaning fluid in the cleaning fluid storage chamber enters the clean water chamber 110 and / or the inlet 1301 sequentially through the cleaning fluid inlet 1308, the cleaning fluid outlet 1309, and the cleaning fluid inlet pipe 102. By setting up a cleaning fluid storage chamber and a cleaning fluid extraction device 190 and installing them on the base station body 100, and designing the connection between the cleaning fluid outlet 1309, the inlet and the cleaning fluid addition pipe 102, the cleaning fluid can be automatically extracted from the storage chamber through the cleaning fluid extraction device 190 and enter the clean water chamber 110 and / or the inlet 1301 through the pipe. There is no need for manual addition of cleaning fluid, which greatly improves the automation level of cleaning the base station, reduces the tedium of manual operation and improves cleaning efficiency.

[0128] If we do not consider various different cleaning scenarios, the cleaning base station of the present invention can be equipped with only one cleaning fluid storage chamber and only one corresponding cleaning fluid inlet 1308, or it can be equipped with two cleaning fluid storage chambers and two corresponding cleaning fluid inlets 1308, so that one cleaning fluid inlet 1308 is connected to one of the cleaning fluid storage chambers, and the other cleaning fluid inlet 1308 is connected to the other cleaning fluid storage chamber. Of course, more cleaning fluid storage chambers and more corresponding cleaning fluid inlets 1308 can also be set in this way.

[0129] In one embodiment, the host's cleaning operation has multiple different scenarios, and different cleaning solutions are required for different scenarios. Therefore, the cleaning base station includes multiple cleaning solution storage chambers for storing different cleaning solutions. These different cleaning solutions are used for various cleaning scenarios. For example, when the host performs cleaning on different room areas or different dirty areas, such as hard floors, bathrooms, or kitchens, different cleaning solutions can be added to the host to make the cleaning more targeted and improve the cleaning effect. The housing of the control valve 130 includes multiple cleaning solution inlets 1308, the number of which is equal to the number of cleaning solution storage chambers, and they are all connected to each other. Of course, different cleaning solutions can also be added for the cleaning of the host's cleaning components. For example, when or after cleaning different room areas or different dirty areas, different cleaning solutions can be used to clean the cleaning components. For instance, after cleaning a fecal area, a deodorizer can be added during the cleaning process to remove odors from the cleaning components, and so on.

[0130] In one embodiment, the third housing 131c may include seven cleaning fluid inlets 1308, each of which is connected to a corresponding cleaning fluid storage chamber. The third valve core 133c also includes a third channel 1333, with a cleaning fluid inlet 13331 and a cleaning fluid outlet 13332 at its two ends. The cleaning fluid inlet 13331 is disposed on the circumferential wall of the third valve core 133c, and the cleaning fluid outlet 13332 is disposed 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 fluid inlet 13331 rotates with the third valve core 133c and sequentially connects with different cleaning fluid inlets 1308, thereby enabling the third channel 1333 to sequentially connect the cleaning fluid outlet 1309 with different cleaning fluid inlets 1308.

[0131] The design incorporates multiple cleaning fluid storage chambers and multiple cleaning fluid inlets 1308, enabling the storage of various types of cleaning fluids, such as specialized cleaning fluids for different types of stains or cleaning requirements. This allows the cleaning base station to utilize a variety of cleaning fluids to address diverse cleaning scenarios and needs, enhancing its applicability and flexibility. Simultaneously, the control valve 130 integrates the first valve section 130a, the second valve section 130b, and the third valve section 130c into a single valve core 133. This not only allows for switching of the cleaning water supply but also enables switching between the opening and closing of the wastewater pipeline 160. Furthermore, it allows for flexible switching between adding cleaning fluid to the main unit's water supply pipeline and the cleaning pipeline, or adding different types of cleaning fluid to either the main unit's water supply pipeline or the cleaning pipeline. This allows for rapid switching between different cleaning fluids as needed during the cleaning process, further improving the timeliness and convenience of adding cleaning fluids.

[0132] The following is an example of adding various cleaning solutions to the main unit's water supply line.

[0133] Referring to Figures 8, 14, and 19, in one embodiment of the present invention, the first housing 131a includes a first liquid outlet 1304 and a liquid storage groove 1323 disposed on the inner wall of the first housing 131a. The first liquid outlet 1304 is connected to the main unit water supply pipe 171. The liquid storage groove 1323 is partially disposed around the outer periphery of the first valve core 133a. The first liquid outlet 1304 or the second liquid outlet 1302 is connected to the liquid storage groove 1323. During the rotation of the first valve core 133a while maintaining the communication between the first channel 1331 and the liquid storage groove 1323, the third valve core 133c connects the cleaning fluid outlet 1309 sequentially to the cleaning fluid inlets 1308 corresponding to at least two main unit water supply pipes.

[0134] Specifically, the first channel 1331 includes an inlet port 13311 and an outlet port 13312. During the rotation of the valve core 133, the inlet port 13311 remains connected to the inlet port 1301 on the housing. The outlet port 13312 is located on the side wall of the valve core 133. As the valve core 133 rotates while maintaining communication between the first channel 1331 and the storage groove 1323, the outlet port 13312 rotates from one end of the storage groove 1323 to the other end along the circumference of the valve core 133, allowing the outlet port to flow out during this process. All liquid inlets 13312 are connected to the first liquid outlet 1304. It should be noted that during the process of the liquid outlet 13312 rotating from one end of the liquid storage groove 1323 to the other end of the liquid storage groove 1323, the cleaning liquid inlet 13331 on the third channel 1333 will also rotate by a corresponding angle. At least two different cleaning liquid inlets 1308 corresponding to the main unit water supply pipe are provided on the housing corresponding to the rotation angle range of the cleaning liquid inlet 13331, so that different cleaning liquids can be added to the main unit water supply pipe 171.

[0135] In scenarios where multiple cleaning solutions need to be added to the main unit's water supply line 171, this design avoids frequent changes of cleaning solutions or the need for multiple independent adding devices, greatly improving the flexibility and versatility of cleaning solution addition and meeting different cleaning needs. Furthermore, the valve body and pipeline have a high degree of integration; the overall structure of the valve body is simple and compact, and the valve body is also relatively easy to control.

[0136] For scenarios where multiple cleaning solutions are added to the cleaning pipeline, please refer to the above description. Correspondingly, the second outlet 1302 connects to the liquid storage groove 1323, and other structures can be flexibly adjusted accordingly, which will not be elaborated further.

[0137] Referring to Figure 19, in one embodiment of the present invention, the housing includes seven cleaning fluid inlets 1308. While the valve core 133 rotates and maintains communication between the first channel 1331 and the liquid storage groove 1323, the third channel 1333 sequentially connects the cleaning fluid outlet 1309 to the six cleaning fluid inlets 1308. This arrangement allows for the addition of six different cleaning fluids to the main unit's water supply line 171 within one rotation cycle of the valve core 133, satisfying more cleaning needs of the main unit. Another cleaning fluid inlet 1308 corresponds to the cleaning line, thus allowing for the replenishment of cleaning fluid to both the main unit's water supply line and the cleaning line simultaneously. Of course, if the cleaning line also requires the replenishment of multiple cleaning fluids, the method described in the above embodiment can also be used, which will not be elaborated here.

[0138] In this invention, the cleaning fluid extraction device 190 can also be installed on the pipe between the cleaning fluid storage chamber and the cleaning fluid inlet 1308. Preferably, in one embodiment of the cleaning base station of this invention, the cleaning fluid extraction device 190 is installed on the cleaning fluid addition pipe 102. By installing the cleaning fluid extraction device 190 on the cleaning fluid addition pipe 102, one cleaning fluid extraction device 190 can extract cleaning fluid from multiple cleaning fluid storage chambers. The valve 130 core can be rotated to a suitable position according to actual cleaning needs, thereby accurately extracting the required cleaning fluid, which not only reduces costs but also improves the compactness of the installation.

[0139] In one embodiment of the cleaning base station of the present invention, the cleaning fluid extraction device 190 shown is a peristaltic pump. The peristaltic pump has a unique squeezing delivery principle. By rolling and squeezing the hose through the pump head, the cleaning fluid is propelled forward within the pipeline, achieving efficient and stable extraction of the cleaning fluid. Even when the cleaning fluid viscosity is high or there is resistance within the pipeline, it maintains a good extraction effect, ensuring smooth delivery of the cleaning fluid and providing a continuous and stable supply of cleaning fluid to the cleaning base station. Furthermore, the peristaltic pump has a relatively simple structure. Its key component, the hose, is in direct contact with the cleaning fluid during use, while other components such as the pump head do not directly contact the cleaning fluid. This makes maintenance and cleaning of the peristaltic pump more convenient; only the hose needs to be replaced periodically, reducing maintenance costs and difficulty. It also helps maintain the hygiene and cleanliness of the cleaning fluid extraction device 190, preventing contamination inside the device from affecting the cleaning effect of the cleaning fluid.

[0140] In this invention, the position of the valve core 133 relative to the housing can also be determined by setting a scale on the housing and a pointer on the valve core 133, and the relationship between the pointer and the scale. Preferably, considering the need for automation, in one embodiment of the clean base station of this invention, the control valve 130 further includes a position detection device 1313 for detecting the position of the valve core 133 relative to the housing. The first valve core 133a, the second valve core 133b, and the third valve core 133c are coaxially rotatably mounted in the housing, 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 housing. The position detection device 1313 can more accurately obtain the position information of the valve core 133, thereby achieving precise control of the rotation angle and position of the valve core 133. This is crucial for operations in the cleaning base station that require precise control of the valve core position, such as switching between various cleaning fluids and different cleaning modes. In this way, the control system of the cleaning base station can control the rotation of the valve core 133 according to the signal from the position detection device 1313, ensuring that the cleaning base station can accurately perform various actions according to the preset program and requirements, thus improving the control accuracy and reliability of the cleaning base station.

[0141] In this invention, the position detection device 1313 can be any suitable device type capable of detecting the position of the valve core 133 relative to the housing, such as a magnetic induction position sensor, a Hall effect position sensor, and a photoelectric position sensor. In one embodiment of the cleaning base station of this invention, the position detection device 1313 includes a detection element 13131 and a sensing element 13132. The sensing element 13132 is fixedly mounted on the valve core 133, and the detection element 13131 is fixedly mounted on the housing and corresponds to the position of the sensing element 13132. The cooperative use of the detection element 13131 and the sensing element 13132 makes the position detection process stable and reliable, not easily affected by external interference, and can continuously and accurately provide feedback information on the position of the valve core 133 to the control system, providing a strong guarantee for the precise control of the cleaning base station. Meanwhile, this separate installation method of the detection element 13131 and the sensing element 13132 allows the detection element 13131 to be installed in a suitable position on the housing and the sensing element 13132 to be installed on the valve core 133 during the assembly of the cleaning base station, making the installation process relatively simple and convenient.

[0142] In one embodiment of the clean base station of the present invention, the detection element 13131 includes a Hall sensor, and the sensing element 13132 includes a magnetic element. The Hall sensor, as the detection element 13131, features high precision and high sensitivity, enabling it to respond quickly and accurately to minute changes in the magnetic field. The magnetic element, as the sensing element 13132, is fixedly connected to the valve core 133. During the rotation of the valve core 133, changes in the magnetic field are generated, and the Hall sensor can accurately detect these magnetic field changes, thereby achieving high-precision detection of the valve core 133's position. Even when the valve core 133's rotation angle is small or its position change is minimal, it can accurately capture position information, providing technical support for the fine control of the clean base station.

[0143] In this invention, the detection element 13131 can be installed on the housing in various ways. For example, it can be snapped onto the housing or directly fixed to the housing via a bolt assembly, but this is not a limitation. Preferably, in one embodiment of the cleaning base station of this invention, the control valve 130 further includes a stop member 1314. A slot is provided on the housing. The detection element 13131 slides into the slot from the opening of the slot. The stop member 1314 is installed into the slot and stops the detection element 13131. With this structural design, when the detection element 13131 malfunctions or needs to be replaced, the stop member 1314 can be removed to easily take the detection element 13131 out of the slot for replacement or repair. There is no need for complex disassembly of the entire control valve 130 or housing, which reduces maintenance costs and repair difficulty and improves the maintainability of the cleaning base station.

[0144] In this invention, the control valve 130 may not include the sensor mounting bracket 13133; instead, the sensor 13132 may be directly fixed to the valve core 133. Preferably, in one embodiment of the clean base station of this invention, the control valve 130 further includes the sensor mounting bracket 13133. A mounting groove is provided on the end face of the valve core 133 near the detection element 13131. The shape of the mounting groove can be any non-rotational shape, as long as the sensor mounting bracket 13133 can be inserted and rotate with the valve core 133. The sensor mounting bracket 13133 is inserted into the mounting groove, and the sensor 13132 is mounted on the sensor mounting bracket 13133. The sensor mounting bracket 13133 not only provides good support and fixation for the sensor 13132, but also allows the sensor 13132 to be placed away from the water inlet. When the sensor 13132 needs to be replaced, calibrated, or adjusted, the sensor mounting bracket 13133 can be easily pulled out of the mounting slot to operate the sensor 13132 without the need for complex processing or modification of the valve core 133. This improves the operability and flexibility of the sensor 13132 and facilitates the smooth maintenance and debugging of the cleaning base station.

[0145] Although the control valve 130 in this invention can be manually controlled, preferably, the cleaning base station has a control system. In one embodiment of the cleaning base station of this invention, the control valve 130 further includes a drive device 134, which drives each valve core to move synchronously, such as driving the first valve core 133a and the second valve core 133b to rotate synchronously within the housing. Both the position detection device 1313 and the drive device 134 are electrically connected to the control system of the cleaning base station. The position detection device 1313 feeds a signal back to the control system, and the control system controls the action of the drive device 134 according to the signal from the position detection device 1313, thereby controlling the rotation or stopping of the valve core 130. By driving the valve core 133 to rotate within the housing through the drive device 134, the rotation of the valve core 133 no longer depends on manual operation or other non-automatic driving methods, thus achieving automatic control of the valve core 133. This provides key technical support for the automated operation of the cleaning base station. It can automatically and precisely control the rotation angle and position of valve 130 core according to preset programs or control commands, thereby realizing functions such as automatic switching of cleaning fluid and automatic conversion of cleaning mode, which greatly improves the intelligence level and work efficiency of the cleaning base station.

[0146] The type of drive device 134 in this invention is not limited as long as the movement of valve core 133 can be achieved. Considering the low rotational speed of valve core 133, please refer to Figure 8. In one embodiment of the clean base station of this invention, the drive device 134 includes a motor and a reduction mechanism. The output shaft 1341 of the motor is connected to the input end of the reduction mechanism, and the output end of the reduction mechanism is connected to any one of the first valve core 133a, the second valve core 133b, and the third valve core 133c. The drive device 134 adopts a combination of a motor and a reduction mechanism. The motor, as a power source, can provide stable and controllable power output, while the reduction mechanism can reduce the high-speed rotation of the motor and transmit it to the valve core 133, so that the valve core 133 can rotate smoothly and accurately at a low speed.

[0147] The type of reduction mechanism in this invention is not limited. For example, it can be a chain drive reduction structure, a belt drive reduction structure, a gear reduction structure, or a combination of the above structures. Preferably, as shown in Figure 20, in one embodiment of the clean base station of this invention, the reduction mechanism includes a meshing gear assembly. The gear assembly includes at least an input gear 1342 and an output gear 1343. The input gear 1342 is fixedly connected to the output shaft 1341 of the motor, and the output gear 1343 is mounted on any one of the first valve core 133a, the second valve core 133b, and the third valve core 133c. Gear meshing transmission has the characteristics of high transmission accuracy, stable transmission ratio, and good torque amplification effect. It can accurately transmit the power of the motor to the valve core 133 and amplify the torque according to the gear tooth ratio, so that the valve core 133 can obtain sufficient torque to drive its rotation with a small motor power, meeting the requirements of the clean base station for the rotation torque of the valve core 133, and improving the transmission efficiency and power utilization effect of the system. Those skilled in the art will understand that a transmission gear can also be provided between the input gear 1342 and the output gear 1343 as needed for deceleration.

[0148] In one embodiment of the clean base station of the present invention, the housing further includes an outer shell 131 and an inner shell 132. The outer shell 131 is made of a rigid material, and the inner shell 132 is made of an elastic material. 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 rigid material, has high strength and rigidity, and can withstand large external pressure and load, providing stable support and protection for the valve core. The addition of the inner shell 132 allows the housing to maintain a certain strength while also possessing good elasticity and sealing performance. It not only forms a good seal between the outer shell 131 and the valve core 133, but also provides conditions for the sealing connection between the valve core 133 and various interfaces on the housing during rotation.

[0149] In one example, the housing includes a first housing and a second housing. Accordingly, the first housing includes a first inner shell and a first outer shell, and the second housing includes a second inner shell and a second outer shell. In one embodiment of the clean base station of the present invention, the housing further includes a first inner shell 1321 and a second inner shell 1322. Both the first outer shell 1311 and the second outer shell 1312 are made of rigid material, while the first inner shell 1321 and the second inner shell 1322 are made of elastic material. 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.

[0150] 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.

[0151] 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.

[0152] In this invention, the gear can be located outside the housing or between the housings corresponding to two valve sections.

[0153] Please refer to 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.

[0154] 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.

[0155] Referring to Figure 8, in this embodiment, for the case where the output gear 1343 is disposed within the gearbox inside the housing, and the first channel 1331, the second channel 1332, and the third channel 1333 are disposed on both sides of the output gear 1343, in order to obtain a better sealing effect, in one embodiment of the clean base station of the present invention, the output gear 1343 is disposed between the first inner shell 1321 and the second inner shell 1322. One end wall of the output gear 1343 is dynamically sealed to the first inner shell 1321 through a first sealing structure, and the other end wall of the output gear 1343 is dynamically sealed to the second inner shell 1322 through a second sealing structure. Examples where the gear is disposed between the housings of other two valve sections are similar and will not be described in detail. This dynamic sealing design effectively prevents cleaning fluid, gas, and other media from leaking through the gap between the output gear 1343 and the inner housing 132 during the rotation of the output gear 1343. It also prevents external impurities from entering the gearbox, ensuring normal gear transmission and a clean environment inside the cleaning base station. This improves the sealing performance and reliability of the cleaning base station, ensuring its stable operation. However, it should be noted that if the axial seal between the valve core 133 and each inner housing 132 is good, a sealing structure may not be necessary between the output gear 1343 and the inner housing 132.

[0156] As long as a dynamic seal can be achieved between the output gear 1343 and the first inner shell 1321 and the second inner shell 1322, the types of the first sealing structure and the second sealing structure in this invention are not limited. For example, O-rings can be provided between the two end faces of the first inner shell 1321, the second inner shell 1322 and the output gear 1343, but this is not a limitation. Please refer to Figures 1 and 2. In one embodiment of the clean base station of this invention, the first sealing structure includes at least one first annular protrusion 13211 disposed on the side of the first inner shell 1321 near the output gear 1343. The first annular protrusion 13211 is coaxially disposed with the output gear 1343 and is sealed against the end wall of the output gear 1343 near the first inner shell 1321. And / or. The second sealing structure includes at least one second annular protrusion 13221 disposed on the side of the second inner housing 1322 near the output gear 1343. The second annular protrusion 13221 is coaxially disposed with the output gear 1343 and is sealed against the end wall of the output gear 1343 near the second inner housing 1322. Examples of gears disposed between the housings of the other two valve sections are similar and will not be described in detail.

[0157] By ensuring a tight fit between the elastic annular protrusion and the end wall of the output gear 1343, a good sealing effect can be provided. The shape, size, and number of the annular protrusion can be adjusted as needed to adapt to different sealing requirements and operating conditions, improving the reliability and adaptability of the seal. Furthermore, due to its reasonable stress distribution and material properties, this sealing structure maintains good sealing performance during long-term use, and is not prone to aging, wear, or deformation, thereby extending the service life of the sealing structure and reducing the maintenance cost of the cleaning base station.

[0158] Referring to Figures 3 and 8, in one embodiment of the cleaning base station of the present invention, the liquid inlet 1301 is disposed on the first housing 131a at one end of the first valve core 133a. An inlet chamber 1324 is disposed inside the first housing 131a at a position opposite to the liquid inlet 1301. The cleaning liquid adding device adds cleaning liquid to the inlet chamber 1324 through the cleaning liquid adding pipe 102. The first channel 1331 includes an inlet interface 13311, which is disposed on the end wall of the first valve core 133a near the inlet chamber 1324 and communicates with the inlet chamber 1324. This design ensures that the liquid inlet 1301 remains connected to the inlet chamber 1324 during the rotation of the first valve core 133a, further ensuring that cleaning water can smoothly enter the first channel 1331 inside the first valve core 133a from the inlet chamber 1324, providing favorable conditions for subsequent liquid distribution and transportation, and helping to improve the overall operating efficiency of the cleaning base station.

[0159] Referring to Figures 8 and 21, in one embodiment of the clean base station of the present invention, 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 13312 communicating with the liquid inlet 13311. The liquid outlet 13312 is disposed on the outer peripheral wall of the valve core 133. During the rotation of the valve core 133, it has a first liquid infusion connection position (position in Figure 10) and a second liquid infusion connection position (position in Figure 11). In the first liquid infusion connection position, the liquid outlet 13312 is connected to the first liquid outlet 1304, and the entire control valve 130 switches to the host liquid infusion state. In the second liquid infusion connection position, the liquid outlet 13312 is connected to the second liquid outlet 1302, and the entire control valve 130 switches to the cleaning liquid infusion state. The liquid outlet 13312 on the valve core 133 achieves alternating communication with the first liquid outlet 1304 and the second liquid outlet 1302 through rotation. This design allows the cleaning station to flexibly switch the liquid output path according to different cleaning needs or working modes, improving the applicability and flexibility of the cleaning station and meeting diverse cleaning task requirements. Furthermore, compared to setting up multiple independent valve cores 133 or complex piping systems to achieve multiple liquid outlets, this method of switching via valve core 133 rotation simplifies the structure, reduces the number and complexity of parts, and lowers production costs and assembly difficulty.

[0160] In one embodiment of the clean water base station of the present invention, the housing further includes a vent 1303, which is connected to the atmosphere through an exhaust channel 101. The exhaust channel 101 is located above the highest liquid level in the clean water tank. During the rotation of the valve core 133, it has a first anti-siphon position (position in the figure) and a second anti-siphon position (position in Figure 14). In the first anti-siphon position, the liquid outlet 13312 is simultaneously connected to the first liquid outlet 1304 and the vent 1303. In the second anti-siphon position, the liquid outlet 13312 is simultaneously connected to the second liquid outlet 1302 and the vent 1303. When the liquid output stops, the connection of the vent 1303 can promptly balance the pressure in the pipeline, preventing siphoning caused by negative pressure in the pipeline, thus improving the safety and reliability of the clean water base station.

[0161] In one embodiment of the cleaning base station of the present invention, a liquid storage groove 1323 is provided on the housing. The liquid storage groove 1323 is partially arranged around the outer periphery of the valve core 133. A first liquid outlet 1304 is connected to the liquid storage groove 1323, and a second liquid outlet 1302 is located in the area outside the liquid storage groove 1323. When the first liquid outlet 13312 is connected to the liquid storage groove 1323, the first liquid outlet 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 ease of docking control of the coaxial valve core in the case of multiple cleaning liquids.

[0162] In one embodiment of the clean base station of the present invention, the housing includes a first liquid outlet 1304 and a second liquid outlet 1302. The valve core 133 differs from the embodiment in FIG. 21. The first channel 1331 includes a first liquid outlet 13312 and a second liquid outlet 13312 connected to the liquid inlet 13311. The first liquid outlet 13312 and the second liquid outlet 13312 are not connected on the outer peripheral wall of the valve core 133, but are independently set like the first gas inlet and the second gas inlet. The first liquid outlet 13312 and the second liquid outlet 13312 are set on the outer peripheral wall of the valve core 133. A sealing part is provided on the inner wall of the housing. Similarly, the valve core 133 has a first liquid inlet connection position and a second liquid inlet connection position during rotation. In the first liquid inlet connection position, the first liquid outlet 13312 is connected to the first liquid outlet 1304, and the sealing part seals and blocks the second liquid outlet 13312. When in the second infusion connection position, the second infusion port 13312 is connected to the second infusion port 1302, and the sealing part seals and blocks the first infusion port 13312.

[0163] The outer peripheral wall of the valve core 133 is provided with a first liquid outlet port 13312 and a second liquid outlet port 13312. The sealing portion on the inner wall of the housing can seal one of these two ports respectively during the rotation of the valve core 133, thereby achieving precise communication and switching between the first liquid outlet port 1304 and the second liquid outlet port 1302 and their corresponding ports. This design not only ensures the sealing of the liquid during the switching process but also improves the accuracy and reliability of liquid switching, enabling the cleaning station to quickly and accurately switch the liquid output path according to different operational needs, thus improving the control precision and working efficiency of the cleaning station.

[0164] In one embodiment of the clean water base station of the present invention, the housing further includes a vent 1303, which can be located between the liquid storage groove 1323 and the second liquid outlet 1302. The vent 1303 is connected to the atmosphere through an exhaust channel 101, which is located above the highest liquid level in the clean water tank. During the rotation of the valve core 133, it has a first anti-siphon position (position in Figure 13) and a second anti-siphon position (position in Figure 14). In the first anti-siphon position, the first liquid outlet 13312 is connected to the first liquid outlet 1304, and the second liquid outlet 13312 is connected to the vent 1303. In the second anti-siphon position, the second liquid outlet 13312 is connected to the second liquid outlet 1302, and the first liquid outlet 13312 is connected to the vent 1303. During the rotation of valve core 133, not only is the connection switching between the first liquid outlet 13312 and the first liquid outlet 1304, and between the second liquid outlet 13312 and the second liquid outlet 1302 achieved, but an anti-siphon function is also cleverly incorporated. In the first anti-siphon position, the first liquid outlet 13312 is connected to the first liquid outlet 1304, and the second liquid outlet 13312 is connected to the vent 1303. In the second anti-siphon position, the second liquid outlet 13312 is connected to the second liquid outlet 1302, and the first liquid outlet 13312 is connected to the vent 1303. This design effectively prevents siphoning during liquid switching, eliminating the need for an additional anti-siphon device, simplifying the structure, reducing costs, and improving the overall performance and reliability of the system.

[0165] In one embodiment of the clean base station of the present invention, the on / off component 150 includes a pneumatic valve, and the second housing 131b further includes a drive air port 1307. The drive gas inlet of the pneumatic valve is connected to the drive air port 1307. The second channel 1332 includes a first interface 13321 and a second interface 13322 that are connected. The first interface 13321 and the second interface 13322 are both disposed on the outer peripheral wall of the valve core 133. During the rotation of the valve core 133, the valve core 133 has a first air-connected position and a second air-connected position. In the first air-connected position, when the second channel 1332 is connected to the air inlet 1305 and the air outlet 1306, the negative pressure device 140 draws gas from the sewage chamber 121 and discharges it through the air outlet 1306. Specifically, in the first air-connected position, one of the first interface 13321 and the second interface 13322 is connected to the air inlet 1305, and the other of the first interface 13321 and the second interface 13322 is connected to the air outlet 1306. In the second air connection position, one of the first interface 13321 and the second interface 13322 is connected to the air inlet 1305, and the other of the first interface 13321 and the second interface 13322 is connected to the drive air port 1307. This design improves the functional integration of the control valve 130, enabling the cleaning station to not only have liquid distribution and delivery functions, but also integrate pneumatic control functions.

[0166] In one embodiment of the clean base station of the present invention, during the rotation of the valve core 133, the valve core 133 also has a third air connection position. In the third air connection position, one of the first interface 13321 and the second interface 13322 is connected to the drive air port 1307, and the other of the first interface 13321 and the second interface 13322 is connected to the air outlet 1306. This design allows the control valve 130 to simultaneously control the opening of the pneumatic valve.

[0167] In this invention, the positions of the air inlet 1305, air outlet 1306, and driving air outlet 1307 are only required to ensure that they can be connected through the second channel 1332 during the rotation of the valve core 133. In one embodiment of the clean base station of this invention, the second valve core 133b is a rotating structure, and the air inlet 1305, air outlet 1306, and driving air outlet 1307 are evenly distributed along the circumference of the valve core 133. This arrangement can provide more space for the installation of pipelines.

[0168] Although the infusion and air extraction can be shut down by closing the clean water flushing device and the negative pressure device 140 in this invention, in one embodiment of the clean base station, during the rotation of the valve core 133 relative to the housing, the control valve 130 also has an infusion blocking state that blocks the inlet 1301 and the outlet, and an exhaust blocking state that blocks the air inlet 1305 and the air outlet 1306. This arrangement can achieve a dual blocking effect and improve the reliability of the blocking. However, those skilled in the art will understand that in some other embodiments, only the infusion blocking state or the exhaust blocking state may be present.

[0169] This invention also provides a clean base station, including a base station body 100, a host water supply pipe 171, a cleaning pipe 172, a clean water chamber 110, multiple cleaning fluid pipes, and a control valve 130. The control valve 130 includes a first valve section 130a and a third valve section 130c. The first valve section 130a includes a first valve core 133a, and the third valve section 130c includes a third valve core 133c. When the first valve core 133a moves, it switches the connection between the clean water chamber 110 and either the host water supply pipe 171 or the cleaning pipe 172. When the third valve core 133c moves, it switches the connection between any one of the multiple cleaning fluid pipes and either the host water supply pipe 171 or the cleaning pipe 172. The first valve core 133a and the third valve core 133c move synchronously. The clean base station of the present invention uses a control valve 130, which includes a first valve section 130a and a third valve section 130c. The first valve section 130a and the third valve section 130c respectively realize the switching control of the clean water circuit and the addition control of the cleaning liquid. There is no need to set up multiple control valves, which simplifies the installation circuit and saves base station space.

[0170] The control valve 130 includes a first valve section 130a and a third valve section 130c. The specific structure, drive control, position detection, etc. of the implementation can be referred to the above embodiments. Some implementations can also be obtained by those skilled in the art based on the implementation of the control valve 130 including the first valve section 130a and the second valve section 130b, which will not be elaborated here.

[0171] The present invention also provides a clean base station, including a base station body 100, a sewage pipe 160, a host water supply pipe 171, a cleaning pipe 172, a clean water chamber 110, multiple cleaning fluid pipes, a switching component 150, a negative pressure device 140, and a control valve 130. The switching component 150 is installed in the sewage pipe 160 and has a blocking state that blocks the sewage pipe 160 and a conducting state that conducts the sewage pipe 160. When the switching component 150 is in the blocking state, the negative pressure device 140 performs air extraction on the sewage chamber 121, so that when the switching component 150 switches to the conducting state, the negative pressure in the sewage chamber 121 can be used to extract sewage from the sewage pipe 160. The control valve 130 includes a second valve section 130b and a third valve section 130c. The second valve section 130b includes a second valve core 133b, and the third valve section 130c includes a third valve core 133c. When the second valve core 133b moves, it switches the on / off assembly 150 to either a blocked state or a connected state. When the third valve core 133c moves, it switches any one of the multiple cleaning fluid pipelines to connect with the host water supply pipeline 171 or the cleaning pipeline 172. The second valve core 133b and the third valve core 133c move synchronously. This invention's cleaning base station, through the control valve 130 including the second valve section 130b and the third valve section 130c, respectively controls the opening and closing of the sewage pipeline 160 and the addition of cleaning fluid, eliminating the need for multiple control valves 130, simplifying the installation circuit, and saving base station space.

[0172] The control valve 130 includes a second valve section 130b and a third valve section 130c. The specific structure, drive control, position detection, etc. of the implementation can be referred to the above embodiments. Some implementations can also be obtained by those skilled in the art based on the implementation of the control valve 130 including a first valve section 130a and a second valve section 130b, and will not be elaborated here.

[0173] In summary, the technical solution of the clean base station of this invention achieves switching between the infusion connection state and the exhaust connection state by connecting the control valve to the negative pressure device, infusion pipeline and clean water chamber on the base station, and by controlling the rotation of the valve core inside the housing. This allows for integrated control of the gas and water circuits, eliminating the need for multiple control valves, simplifying the installation circuit, and saving base station space. Therefore, this invention effectively overcomes some practical problems in the prior art, thus possessing high utilization value and practical significance. The above embodiments are merely illustrative of the principles and effects of this invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this invention.
