DETAILED DESCRIPTION

[0073] The following is an explanation of the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the features in the following embodiments and the embodiments can be combined with each other without conflict. It should also be understood that the terms used in the embodiments of the present invention are intended to describe specific embodiments, rather than to limit the scope of protection of the present invention. The test methods for which specific conditions are not specified in the following examples are usually carried out under conventional conditions or according to the conditions recommended by the manufacturers.

[0074] When numerical ranges are given in the embodiments, it should be understood that, unless otherwise specified in the present invention, both endpoints of each numerical range and any value between the two endpoints can be selected. Unless otherwise defined, all technical and scientific terms used in the present invention are familiar to those skilled in the art and the description of the present invention, and any methods, equipment and materials of the prior art similar or equivalent to the methods, equipment and materials described in the embodiments of the present invention can also be used to implement the present invention.

[0075] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" etc. used in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships, without substantially changing the technical content, should also be regarded as the scope of implementation of the present invention.

[0076] See also 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 sweeping and mopping robot, etc. The cleaning base station may be used to realize one or more functions of the sweeping and mopping robot, such as charging, cleaning component cleaning, and garbage collection.

[0077] See also Figures 1 to 3 The cleaning 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 arranged on the base station body 100.

[0078] The appearance of the base station body 100 is not limited. For example, the base station body 100 may be roughly rectangular in shape as a whole, or may be rectangular in shape at the bottom and spherical in shape at the top. However, the base station body 100 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 chamber 121 are not limited. For example, it can be directly set on the base station body 100, or a detachable sewage tank 120 can be set on the base station body 100. The sewage chamber 121 is a storage space formed in the sewage tank 120. The structure and wall thickness of the sewage chamber 121 are convenient for manufacturing, and it is suitable to have sufficient strength and not deform when the negative pressure is pumped to a set threshold. One end of the sewage pipe 160 is connected to the uppermost liquid level of 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 refer to the diameter of the sewage pipe 160 on the existing base station. In some embodiments, the minimum inner diameter of the sewage pipe 160 is greater than 18 mm and less than 25 mm.

[0080] The negative pressure device 140 can perform an air extraction operation on the sewage chamber 121 to reduce the air pressure in the sewage chamber 121. Based on the pressure difference, the sewage enters the sewage chamber 121 through the sewage pipe 160. The negative pressure device 140 can be any suitable device capable of extracting gas, such as a vacuum pump, a centrifugal exhaust fan, an axial flow exhaust fan, a plunger pump, etc., but is not limited thereto. There is no limit to the communication method between the air suction port of the negative pressure device 140 and the sewage chamber 121. For example, a hole can be opened on the wall above the highest liquid level of the sewage chamber 121 to form an air suction hole, and the air suction port of the negative pressure device 140 can be directly connected to the air suction hole, or the air suction port of the negative pressure device 140 can be indirectly connected to the air suction hole through a pipeline. Specifically, in this embodiment, the air suction port of the negative pressure device 140 is connected to the sewage chamber 121 through an air suction pipe 103, one end of the air suction pipe 103 is connected to the air suction port of the negative pressure device 140, and the other end of the air suction pipe 103 is connected to the wall of the chamber above the highest liquid level of the sewage chamber 121.

[0081] The base station body 100 may include a housing cavity, which is disposed at the bottom of the base station body 100 and has an opening for the host to enter. A charging terminal that can be electrically connected to a charging device to charge the host may also be disposed in the housing cavity. 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.

[0082] In some embodiments, the cleaning base station may further include a cleaning tank 180 for cleaning the cleaning components of the host, and the cleaning tank 180 is formed in the accommodating cavity. One end of the sewage pipe 160 is connected to the uppermost liquid level of the sewage cavity 121, and the other end of the sewage pipe 160 is connected to the cleaning tank 180. For example, a trumpet-shaped sewage suction port may be provided in the cleaning tray, and the sewage suction port is at the lowest point of the cleaning tank 180, and the other end of the sewage pipe 160 may be connected to the sewage suction port.

[0083] However, it should be noted that in other embodiments, the cleaning tank 180 may not be provided. For example, a sewage box may be provided on the host. During the cleaning process of the host, the cleaning components may be cleaned, and the cleaned sewage is stored in the sewage box. When the host is docked with the base station, the sewage box may be docked with the sewage pipe 160, and the sewage pipe 160 extracts 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 pipe 160 is connected to the top of the sewage chamber 121, and the other end of the sewage pipe 160 is connected to the bottom of the sewage box on the host, thereby realizing the sewage extraction work of the sewage in the host.

[0084] In some embodiments, the base station body 100 may also be provided with an on-off assembly 150. The on-off assembly 150 is provided on the sewage pipe 160, and the on-off assembly 150 has a blocking state in which the sewage pipe 160 is blocked and a conducting state in which the sewage pipe 160 is conducted. The on-off assembly 150 may be a pneumatic valve or a hydraulic valve. For example, the pneumatic valve has an air cavity and a flexible extrusion portion, and the air cavity is located outside the flexible extrusion portion. When the gas in the air cavity increases, the gas prompts the flexible extrusion portion to squeeze and block the water flow of the sewage pipe 160. When the gas in the air cavity decreases, the flexible extrusion portion recovers its deformation in a direction away from the sewage pipe, and the sewage pipe 160 is conducted. For example, the sewage pipe 160 is a flexible structure, and the flexible extrusion portion may be provided outside the sewage pipe 160. When the gas in the air cavity increases, the flexible extrusion portion protrudes toward the sewage pipe 160 side, squeezing and blocking the water flow of the sewage pipe 160. After the gas in the air cavity decreases, the flexible extrusion part recovers its deformation in the direction away from the sewage pipe, and the sewage pipe 160 is opened. Alternatively, the sewage pipe 160 is divided into two sections, and the pneumatic valve is arranged between the two sections. After the gas in the air cavity increases, the gas causes the flexible extrusion part to bulge inward, squeezing and blocking the water flow of the sewage pipe 160. After the gas in the air cavity decreases, the flexible extrusion part recovers its deformation, and the sewage pipe 160 is opened.

[0085] When the on-off assembly 150 is in the blocking state, the sewage chamber 121 can be evacuated, so that when the on-off assembly 150 is switched to the on state, the sewage pipeline 160 can be evacuated by the negative pressure in the sewage chamber 121 .

[0086] For example, when the on-off component 150 is switched to the blocking state, the negative pressure device 140 can perform an air extraction operation on the sewage chamber 121 so that the negative pressure in the sewage chamber 121 reaches the set threshold value. When the negative pressure in the sewage chamber 121 is maintained at the set threshold value, the on-off component 150 is switched to the on state, and the sewage in the cleaning tank 180 is sucked 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 selection of the set threshold value can be obtained by comprehensive calculation based on the volume of the liquid to be pumped, the diameter of the sewage pipe 160, and the suction distance, or it can be obtained through experiments. For example, the negative pressure threshold in the sewage chamber 121 can be set to pump all the sewage in the cleaning tank 180 into the sewage chamber 121 at one time. 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 value can be 30Kpa. It should also be noted that, taking into account the existence of errors, slight fluctuations above and below the set threshold are considered "maintained", and slight fluctuations refer to ±10Kpa.

[0087] By setting a switch assembly 150 corresponding to the sewage pipe 160, the sewage pipe 160 can be cut off, so that a closed space is formed inside the sewage chamber 121. In this way, under the action of the negative pressure device 140, a large negative pressure can be formed in the sewage chamber 121, which effectively improves the sewage pumping speed and reduces the time used for sewage pumping. At the same time, it can also reduce the mixing of gas and sewage, thereby reducing the bubble sound. In addition, compared with the suction operation method of pumping air while sucking sewage, a greater suction force can be obtained, which can increase the carrying rate of deposited impurities in the cleaning tank 180, reduce the dirt deposition at the bottom of the cleaning tank 180, and is more conducive to achieving maintenance-free cleaning tank 180.

[0088] The shape and structure of the clean water chamber 110 are also not limited, and specific reference can be made to the existing structure. The clean water chamber 110 is used to hold clean water, provide clean water supply for the host to clean the ground, and / or provide clean water supply for cleaning the cleaning components of the host. The base station body 100 may be provided with a host water replenishment pipeline 171 and a cleaning pipeline 172. The host water replenishment pipeline 171 may be connected to the clean water chamber 110 and the clean water box of the host, and the cleaning pipeline 172 may be connected to the clean water chamber 110 and the cleaning tank 180. For example, the base station body 100 is provided with a host water replenishment port (not shown) for replenishing water for the host and a cleaning water spray port (not shown) for providing clean water during the cleaning of the cleaning components of the host. The host water replenishment pipeline 171 connects the clean water chamber 110 and the host water replenishment port, and the cleaning pipeline 172 connects the clean water chamber 110 and the cleaning water spray port. The sewage generated after the cleaning components are cleaned can enter the sewage pipeline 160 through the sewage suction port of the cleaning tank 180 and then enter the sewage chamber 121 .

[0089] The infusion pipeline 170 may be a main unit water supply pipeline 171 or a cleaning pipeline 172 , or the infusion pipeline 170 may include a main unit water supply pipeline 171 and a cleaning pipeline 172 .

[0090] The control valve 130 is installed on the base station body 100, and the installation method is not limited. In some embodiments, the control valve 130 can be detachably connected to the base station body 100 to facilitate maintenance.

[0091] When the sewage pipeline 160, the main machine water supply pipeline 171, the cleaning pipeline 172, the sewage chamber 121, and the clean water chamber 110 are provided on the base station body 100, and the on-off assembly 150 is provided on the sewage pipeline 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, the clean water chamber 110 is switched to be connected with any one of the main machine water supply pipeline 171 and the cleaning pipeline 172, and when the second valve core 133b moves, the on-off assembly 150 is switched to any one of the blocking state and the conducting state. The first valve core 133a and the second valve core 133b move synchronously. By controlling the synchronous movement of the two valve cores to realize the switching of the clean water circuit and the opening and closing of the sewage pipeline 160, the drive structure and / or control structure of the control valve 130 can be further simplified, the integration of the valves in the base station can be improved, and the base station space can be saved. For example, the position detection and drive of the movement of the two valve cores can be realized by sharing a set of position detection elements 13131 and / or a set of driving devices 134.

[0092] For example, 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 part can be connected to the first valve core 133a and the second valve core 133b, and a Hall sensor can be used to cooperate with the magnetic part for detection. Since the first valve core 133a and the second valve core 133b move synchronously, the first valve core 133a and the second valve core 133b rotate at the same angle or move at the same length, so that the signals detected by the Hall sensor are the same, that is, the signals can be used to simultaneously realize the switching of the clean water circuit and the opening and closing of the sewage pipeline 160. For example, when the movement mode of the first valve core 133a and the second valve core 133b is rotation, the above-mentioned set of detection elements 13131 detects the parameter of the rotation angle of the two valve cores, so as to realize the synchronous detection of the switching of the clean water circuit and the opening and closing of the sewage pipeline 160, thereby reducing the number of detection elements 13131 and saving base station space.

[0093] The same set of driving devices 134 can also be used to control the synchronous movement of the first valve core 133a and the second valve core 133b, thereby reducing one set of driving devices 134 and saving base station space. 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 are connected, which can more conveniently realize the synchronous movement of the two valve cores, and the two valve cores are more integrated. 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 adopt an integrally molded structure. The integrally molded design integrates the two valve cores that originally needed to be processed and assembled separately into a whole, reducing the number of parts and assembly links. At the same time, the first valve core 133a and the second valve core 133b are integrally molded, which makes it easier to control the synchronous movement of the two, and there will be no movement deviation, thereby ensuring control accuracy.

[0095] The control valve 130 may further include a housing. The structure and shape of the housing are not limited. Specifically, the housing is classified according to the corresponding valve core, and 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 may be detachably connected or fixedly connected, or may be integrally formed. The first housing 131a and the second housing 131b may be a single-layer shell structure or a multi-layer shell structure. The movement of the first valve core 133a in the first housing 131a and the movement of the second valve core 133b in the second housing 131b may 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 clean water chamber 110 to communicate 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 to enter any one of the blocking state and the conducting state. Compared with the state switching by linear movement, the switching of the connected state by rotation has relatively small fluid resistance, and has higher 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 additional space occupation, making the base station more integrated.

[0097] In an embodiment of 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. A first channel 1331 is provided in the first valve core 133a. A liquid inlet 1301, a first liquid outlet 1304 connected to the main machine water supply pipeline 171, and a second liquid outlet 1302 connected to the cleaning pipeline 172 are provided on the first housing 131a. When the first channel 1331 is connected to the liquid inlet 1301 and the first liquid outlet 1304, the clean water chamber 110 is connected to the main machine water supply pipeline 171. When the first channel 1331 is connected to the liquid inlet 1301 and the second liquid outlet 1302, the clean water chamber 110 is connected to the cleaning pipeline 172. The liquid inlet 1301 is connected to the clean water chamber 110. For example, a clean water pump may be installed on the base station body 100 , and the clean water pump is located on a connecting pipe between the clean water chamber 110 and the liquid inlet 1301 to provide power for clean water to enter the liquid inlet 1301 .

[0098] Liquid flow ports (such as liquid inlet 1301, first liquid outlet 1304, second liquid outlet 1302) are arranged on the shell, and channels are arranged on the corresponding valve cores. By switching the channels to connect with different liquid flow ports, the switching of the main unit water supply pipeline 171 and the cleaning pipeline 172 can be realized, and the structure is simpler and more compact. Further, based on this structure, the control valve 130 core rotates relative to the shell to realize the connection between the channels and different liquid flow ports, and the simplicity of the structural settings such as driving and position detection can also be reduced.

[0099] In one embodiment of the cleaning base station, the on-off component 150 can be a pneumatic valve, and the base station body 100 is provided with an air intake channel and an exhaust pipe 101. When the pneumatic valve is connected to the air intake channel, the gas enters the air cavity through the air intake channel. When the pneumatic valve is connected to the exhaust pipe 101, the gas flows out of the air cavity through the exhaust pipe 101. The second valve section 130b switches the pneumatic valve to be connected to any one of the air intake channel and the exhaust pipe 101. By switching the connection state of the pneumatic valve and the air intake channel or the exhaust pipe 101, the gas can enter or discharge the pneumatic valve. The pneumatic valve has high sealing and reliability. Using the pneumatic valve as the on-off component 150 can improve the sealing and reliability of the sewage pipe blocking and conducting.

[0100] In some embodiments, the negative pressure device 140 is connected to the air inlet channel, and the negative pressure device 140 extracts the gas in the sewage chamber 121 and delivers it to the air inlet pipe so that the gas enters the air chamber. This configuration only requires one negative pressure device 140 and one pneumatic valve, which can not only perform air extraction operations on the sewage chamber 121, but also achieve blocking and conduction of the sewage pipe, further saving the internal space of the base station. In addition, by driving the pneumatic valve with the gas extracted from the sewage chamber 121, it is also possible to simultaneously pump negative pressure into the sewage chamber 121 when the sewage pipe is blocked, saving the time of continuing to pump negative pressure into the sewage chamber 121 after blocking the sewage pipe, and the pneumatic valve requires less gas, and the negative pressure pumped into the sewage chamber 121 at the beginning will not cause sewage to enter the sewage pipe, or only allow less sewage to enter the sewage pipe, which will not have a significant impact on the blocking of the sewage pipe.

[0101] Of course, the air inlet channel in the present invention may also be connected to other air pumps configured separately, as long as the gas can enter the air cavity to achieve the switching of the sewage pipe 160 between the blocking state and the conducting state.

[0102] In an embodiment of the clean base station, the exhaust pipe 101 is connected to the atmosphere so that the gas is discharged from the air cavity into the atmosphere, and the gas of the pneumatic valve is directly discharged into the atmosphere without setting up additional pipes, which can further save the internal space of the base station. Of course, the gas of the pneumatic valve in the present invention can also flow back to the sewage cavity 121 through a separately set pipeline. In the case where the gas of the pneumatic valve comes from the sewage cavity 121, the gas is discharged into the atmosphere again, which will cause the gas with odor to enter the atmosphere, affecting the user experience.

[0103] In one 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. A second channel 1332 is provided in the second valve core 133b. The second housing 131b is provided with a driving air port 1307, an air inlet 1305 and an air outlet 1306, the air inlet 1305 is connected to the air inlet channel, and the air outlet 1306 is connected to the exhaust pipe 101. The driving air port 1307 is connected to the air cavity of the pneumatic valve. When the second channel 1332 is connected to the driving air port 1307 and the air inlet 1305, the pneumatic valve is connected to the air inlet channel. When the second channel 1332 is connected to the driving air port 1307 and the air outlet 1306, the pneumatic valve is connected to the exhaust pipe 101.

[0104] The housing is provided with gas flow ports (such as the driving gas port 1307, the air inlet 1305 and the air outlet 1306), and the corresponding valve core is provided with channels. By switching the channels to communicate with different gas flow ports, the sewage pipeline 160 can be opened and closed, and the structure is simpler and more compact. Further, based on this structure, the control valve 130 core rotates relative to the housing to realize the communication between the channels and different gas flow ports, and the simplicity of the structural settings such as the driving and position detection can also be reduced.

[0105] In some embodiments, the first valve core 133a is rotatably mounted in the first housing 131a, and the second valve core 133b is rotatably mounted in the second housing 131b. The first valve core 133a and the second valve core 133b are rotated to different angles, corresponding to different liquid flow ports and gas flow ports. Fig.21 , the first valve core 133a includes a first channel 1331, and the second valve core 133b includes a second channel 1332. In the process that the first valve core 133a rotates relative to the first housing 131a and the second valve core 133b rotates relative to the second housing 131b, the channel of the valve core 133 of the control valve 130 and the liquid flow ports on the housing (refer to Fig.10 and Fig.11 ), the switching connection relationship of each gas flow port (reference Fig.16 ). By setting the control valve 130, the control of clean water replenishment and sewage extraction can be realized, so that the integration of the valve structure, drive and control can be higher, and the base station space can be saved.

[0106] See also Figure 3 and Fig.17 In one embodiment of the cleaning base station of the present invention, the on-off assembly 150 includes a pneumatic valve installed on the sewage pipe 160, and the second shell 131b also includes a driving gas port 1307. The driving gas inlet of the pneumatic valve is connected to the driving gas port 1307. The driving gas inlet and the driving gas port 1307 can be directly connected or indirectly connected. In this embodiment, the driving gas inlet can be connected to the driving gas port 1307 through the driving pipe 104.

[0107] During the rotation of the valve core 133 relative to the housing, the control valve 130 also has a valve driving state in which the air inlet 1305 and the air outlet 1306 are blocked, and the air inlet 1305 and the driving air port 1307 are connected through the second channel 1332 .

[0108] The pneumatic pinch valve can be vented by providing a pressure relief port to open the sewage pipe 160. Preferably, in an embodiment of the cleaning base station of the present invention, the pressure relief port on the pneumatic valve and the driving gas inlet are the same interface. Fig.18During the rotation of the second valve core 133b relative to the second shell 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. When the valve is in the valve exhaust state, the gas in the air cavity of the pneumatic valve is discharged from the air cavity, and the pneumatic valve is switched to the conducting state, and the sewage pipe 160 can perform sewage pumping operations.

[0109] 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 connected 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, 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 connected to the atmosphere through the exhaust pipe 101. In this way, when the negative pressure device 140 evacuates the sewage chamber 121, the control valve 130 can be switched to a valve driving state in which the air inlet 1305 and the driving air port 1307 are connected through the second channel 1332. The gas extracted from the sewage chamber 121 by the negative pressure device 140 can drive the pneumatic valve to operate and achieve the blocking of the sewage pipeline 160. It can be seen that the control valve 130 of the present invention can drive the pneumatic valve through the negative pressure device 140, and there is no need to set up a negative pressure device 140, other valves or adapters, so as to achieve the blocking and conduction of the sewage pipeline 160, simplifying the system design, reducing manufacturing and maintenance costs, and saving internal space of the base station.

[0110] 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 blocking state, the second channel 1332 of the second valve core 133b is controlled to be connected to the air inlet 1305 and the air outlet 1306, and the negative pressure device 140 performs a pumping operation on the sewage chamber 121. When the negative pressure value in the sewage chamber 121 reaches the required value, the second channel 1332 of the second valve core 133b can be controlled to be connected to the air cavity of the pneumatic valve and the air outlet 1306, the gas in the air cavity of the pneumatic valve is discharged, the pneumatic valve is switched to the conducting state, the sewage pipeline 160 is conducted, 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 arrangement can realize the control of pumping negative pressure into the sewage chamber 121, blocking the sewage pipeline 160, and opening the sewage pipeline 160 through the same control valve 130, which greatly reduces the number of parts of the control valve 130, simplifies the overall structure, and thus reduces production costs.

[0111] See also Figure 3 , Figure 5 and Fig.10In an embodiment of the cleaning base station of the present invention, the first liquid outlet 1304 is connected to the main unit water supply pipeline 171, and during the rotation of the first valve core 133a relative to the first housing 131a, the control valve 130 has a main unit liquid infusion state in which the liquid inlet 1301 and the first liquid outlet 1304 are connected through the first channel 1331. In this state, the liquid inlet 1301 is connected to the first liquid outlet 1304, and the clean water in the clean water chamber 110 flows into the main unit water supply pipeline 171 under the action of gravity or the clean water pump, thereby providing water supply for the clean water box of the main unit.

[0112] See also Figure 3 , Figure 5 and Fig.13 In an embodiment of the cleaning base station of the present invention, the first housing 131a further includes a vent 1303 connected to the atmosphere, the vent 1303 is connected to the atmosphere through the exhaust pipe 101, and the position where the exhaust pipe 101 is connected to the atmosphere is located above the highest liquid level of 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 of the host water replenishment 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 siphon condition that may be formed, and effectively preventing the host water replenishment pipeline 171 from siphoning the clean water chamber 110 when the liquid stops infusion.

[0113] In an 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 liquid infusion state in which the liquid inlet 1301 and the second liquid outlet 1302 are connected through the first channel 1331. When the host enters the cleaning tank 180, the liquid inlet 1301 and the second liquid outlet 1302 can be connected through 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 the clean water pump, and can provide a clean water supply for cleaning the cleaning parts of the host.

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

[0115] The first liquid outlet 1304 is connected to the main machine water supply pipeline 171, and the second liquid 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 machine liquid infusion state in which the liquid inlet 1301 and the first liquid outlet 1304 are connected through the first channel 1331, and a cleaning liquid infusion state in which the liquid inlet 1301 and the second liquid outlet 1302 are connected through the first channel 1331. The main machine liquid infusion state and the cleaning liquid infusion state can be mutually exclusive, that is, during the rotation of the valve core 133, only the first channel 1331 can be connected to one of the first liquid outlet 1304 and the second liquid outlet 1302. The main machine liquid infusion state and the cleaning liquid infusion state can also be simultaneously available, that is, during the rotation of the first valve core 133a, the first channel 1331 can be simultaneously connected to the first liquid outlet 1304 and the second liquid outlet 1302. Such a configuration not only enables the cleaning base station to have more integrated functions, but also can integrate the control of multiple infusion pipelines 170 through the same control valve 130, which can save costs and simplify the installation process of the waterway.

[0116] In an embodiment of the cleaning base station of the present invention, the first shell 131a further includes a vent 1303 connected to the atmosphere, the vent 1303 is connected to the atmosphere through the exhaust pipe 101, and the position where the exhaust pipe 101 is connected to the atmosphere is located above the highest liquid level of the clean water tank. During the rotation of the first valve core 133a relative to the first shell 131a, the control valve 130 also has an anti-siphon state of the cleaning infusion pipeline 170, in which the liquid inlet 1301 is connected to the vent 1303 and the second liquid outlet 1302 at the same time through the first channel 1331. Similar to the anti-siphon state of the main machine water replenishment pipeline 171, the liquid inlet 1301 is connected to the vent 1303 and the second liquid outlet 1302 at the same time through the rotation of the first valve core 133a, so that the second liquid outlet 1302 is connected to the atmosphere, thereby preventing the cleaning infusion pipeline 170 from siphoning the clean water chamber 110 after the cleaning is completed.

[0117] It should be noted that, in the present 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 machine water replenishment pipeline 171, the vent 1303 is connected to the atmosphere through the exhaust pipe 101, and the position where the exhaust pipe 101 is connected to the atmosphere is located above the highest liquid level of the clean water tank. During the rotation of the first valve core 133a relative to the shell, the control valve 130 has both the anti-siphon state of the main machine water replenishment pipeline 171 in which the liquid inlet 1301 is connected to the vent 1303 and the first liquid outlet 1304 at the same time through the first channel 1331, and the anti-siphon state of the cleaning infusion pipeline 170 in which the liquid inlet 1301 is connected to the vent 1303 and the second liquid outlet 1302 at the same time through the first channel 1331.

[0118] Along the rotation direction of the first valve core 133a, the vent 1303 is arranged between the first liquid outlet 1304 and the second liquid outlet 1302. When the host infusion is finished, the first valve core 133a can be rotated to directly switch from the host infusion state to the anti-siphon state of the host water supply pipeline 171. When the infusion of the cleaning tank 180 is finished, the first valve core 133a can also be rotated in the opposite direction to directly switch from the cleaning infusion state to the anti-siphon state of the cleaning infusion pipeline 170. This arrangement enables the cleaning base station to have more integrated functions, and the control of multiple infusion pipelines 170 can be integrated through the same control valve 130, which can save costs and simplify the installation process of the waterway.

[0119] The cleaning base station of the present invention may not have the function of adding cleaning liquid, but may realize the addition of cleaning liquid manually. Preferably, in one embodiment of the cleaning base station of the present invention, the cleaning base station further includes a cleaning liquid extracting device 190, which is installed on the base station body 100. The cleaning liquid extracting device extracts cleaning liquid from the cleaning liquid outlet 1309 and adds it to the main unit water supply pipeline 171 or the cleaning pipeline 172.

[0120] In one embodiment of the cleaning base station of the present invention, the cleaning base station also includes a multi-channel cleaning liquid pipeline, the control valve 130 also includes a third valve section 130c, and the third valve section 130c includes a third valve core 133c. When the third valve core 133c moves, any one of the multi-channel cleaning liquid pipelines is switched to be connected to the main machine water supply pipeline 171 or the cleaning pipeline 172. Among them, 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 part of the synchronous movement can refer to the above embodiment, and will not be repeated here. The switching control of the cleaning water circuit is achieved through the first valve section 130a, the opening and closing control of the sewage pipe 160 is achieved through the second valve section 130b, and the addition control of the cleaning liquid is achieved through the third valve section 130c. There is no need to set up multiple control valves 130, which can simplify the installation circuit and save base station space.

[0121] In one embodiment of the cleaning base station of the present invention, the third valve section 130c may include a third housing 131c, the third housing 131c includes a cleaning liquid outlet 1309 and a plurality of cleaning liquid inlets 1308, and the plurality of cleaning liquid inlets 1308 are respectively connected to different cleaning liquid pipelines, and the third valve core 133c includes a third channel 1333. When the third channel 1333 is connected to the cleaning liquid outlet 1309 and any cleaning liquid inlet 1308, the cleaning liquid pipeline corresponding to the cleaning liquid inlet 1308 is connected to the main machine water supply pipeline 171 or the cleaning pipeline 172. A liquid flow port (such as a cleaning liquid outlet 1309 and a plurality of cleaning liquid inlets 1308) is provided on the housing, and a channel is provided on the valve core 133. By switching the channel to connect with different liquid flow ports, the switching of multiple cleaning liquids can be realized, and the structure is simpler and more compact. Further, on the basis of this structure, the control valve 130 core rotates relative to the housing to realize the connection between the channel and different liquid flow ports, and the simplicity of the structural setting such as the drive and position detection can also be reduced.

[0122] The cleaning liquid outlet 1309 can be connected only to the clean water chamber 110 or the liquid inlet 1301 through the cleaning liquid adding pipe 102, or it can be connected to both the clean water chamber 110 and the liquid inlet 1301 through the cleaning liquid adding pipe 102. The cleaning liquid inlet 1308 is connected to the cleaning liquid storage chamber. The cleaning liquid storage chamber can be set on the base station body 100, or it can be directly the inner cavity of the cleaning agent storage bottle.

[0123] The first valve core 133a, the second valve core 133b, and the third valve core 133c may also be connected in other ways. For details, please refer to the above-mentioned connection method of the first valve core 133a and the second valve core 133b, which will not be described here. In one embodiment of the cleaning 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 may be integrally formed, or the first valve core 133a, the second valve core 133b, and the third valve core 133c may be integrated into 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 into one valve core 133, and are integrally formed. This does not require the installation of additional parts, which can improve assembly efficiency and installation accuracy.

[0124] 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 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 rotate coaxially, 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, if the axial direction of the control valve is the height direction of the base station, the first valve core 133a can be set at the uppermost end to facilitate the anti-siphon pipeline setting, the second valve core 133b is in the middle, and the third valve core 133c is at the lowermost end. Of course, the figure is only a preferred example, 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 layout.

[0125] In an embodiment of the cleaning base station of the present invention, 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, a cleaning liquid addition port 1310 is provided on the first housing 131a of the control valve 130, the cleaning liquid addition port 1310 is connected to the liquid inlet 1301, one end of the cleaning liquid addition pipeline 102 is connected to the cleaning liquid outlet 1309, and the other end of the cleaning liquid addition pipeline 102 is connected to the cleaning liquid addition port 1310. Under the action of the cleaning liquid extraction device 190, the cleaning liquid in the cleaning liquid storage chamber enters the clean water chamber 110 and / or the liquid inlet 1301 in sequence through the cleaning liquid inlet 1308, the cleaning liquid outlet 1309, and the cleaning liquid addition pipeline 102. By providing a cleaning liquid storage chamber and a cleaning liquid extraction device 190, and installing them on the base station body 100, and designing the connection method between the cleaning liquid outlet 1309, the inlet and the cleaning liquid adding pipeline 102, the cleaning liquid can be automatically extracted from the storage chamber through the cleaning liquid extraction device 190, and enter the clean water chamber 110 and / or the liquid inlet 1301 through the pipeline, without the need for manual addition of cleaning liquid, which greatly improves the degree of automation of the cleaning base station, reduces the tediousness of manual operation, and improves the cleaning efficiency.

[0127] If a variety of different cleaning scenarios are not considered, the cleaning base station of the present invention may only have one cleaning liquid storage chamber and one corresponding cleaning liquid inlet 1308, or two cleaning liquid storage chambers may be provided, and two corresponding cleaning liquid inlets 1308 may be provided, so that one cleaning liquid inlet 1308 is connected to one of the cleaning liquid storage chambers, and the other cleaning liquid inlet 1308 is correspondingly connected to the other cleaning liquid storage chamber. Of course, more cleaning liquid storage chambers may be provided by analogy, and more cleaning liquid inlets 1308 may be provided accordingly.

[0128] In one embodiment, the cleaning operation of the host has multiple different scenes, and different cleaning liquids need to be used for different scene operations. Therefore, the cleaning base station includes multiple cleaning liquid storage chambers, and the multiple cleaning liquid storage chambers are used to store different cleaning liquids. Different cleaning liquids are used for multiple cleaning scenes. For example, when the host performs cleaning for different room areas or different dirty areas such as cleaning hard floors, cleaning bathrooms, and cleaning kitchens, different cleaning liquids can be added to the host to make the cleaning of the corresponding areas more targeted and improve the cleaning effect. The housing of the control valve 130 includes multiple cleaning liquid inlets 1308, and the number of multiple cleaning liquid inlets 1308 is equal to that of the multiple cleaning liquid storage chambers, and they are connected to each other. Of course, different cleaning liquids can also be added to the cleaning operation of the cleaning parts of the host. For example, when or after the cleaning of different room areas or different dirty areas of the host is performed, different cleaning liquids can be used to clean the cleaning parts. For example, after the cleaning parts clean the feces area, deodorants can be further added to the cleaning parts to remove the odor on the cleaning parts, and so on.

[0129] In one embodiment, the third housing 131c may include seven cleaning liquid inlets 1308, each of which is connected to a corresponding cleaning liquid storage chamber. The third valve core 133c also includes a third channel 1333, and the two ends of the third channel 1333 are respectively a cleaning liquid inlet interface 13331 and a cleaning liquid outlet interface 13332, the cleaning liquid inlet interface 13331 is arranged on the circumferential wall 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. When the third valve core 133c rotates relative to the third housing 131c, the cleaning liquid inlet interface 13331 rotates with the third valve core 133c and docks with different cleaning liquid inlets 1308 in sequence, so that the third channel 1333 connects the cleaning liquid outlet 1309 with different cleaning liquid inlets 1308 in sequence.

[0130] Through the design of multiple cleaning liquid storage chambers and multiple cleaning liquid inlets 1308, different types of cleaning liquids can be stored, such as special cleaning liquids for different stain types or cleaning requirements, so that the cleaning base station has the ability to use multiple cleaning liquids to cope with various cleaning scenarios and needs, thereby improving the applicability and flexibility of the cleaning base station. At the same time, the control valve 130 integrates the first valve section 130a, the second valve section 130b, and the third valve section 130c into a valve core 133, which can not only realize the switching of the cleaning water supply, but also realize the switching of the conduction and blocking of the sewage pipeline 160, and can also realize the flexible switching of replenishing cleaning liquid to the main unit water supply pipeline and the cleaning pipeline respectively, or replenishing different types of cleaning liquid to the main unit water supply pipeline / cleaning pipeline, and can quickly switch to use different cleaning liquids as needed during the cleaning process, further improving the timeliness and convenience of adding cleaning liquid.

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

[0132] See also Figure 8 , Fig.14 and Fig.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 pipeline 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. When the first valve core 133a rotates and keeps the first channel 1331 connected to the liquid storage groove 1323, the third valve core 133c enables the cleaning liquid outlet 1309 to be connected to the cleaning liquid inlets 1308 corresponding to at least two main unit water supply pipelines in sequence.

[0133] Specifically, the first channel 1331 includes a liquid inlet interface 13311 and a liquid outlet interface 13312. During the rotation of the valve core 133, the liquid inlet interface 13311 is always connected to the liquid inlet 1301 on the shell, and the liquid outlet interface 13312 is arranged on the side wall of the valve core 133. During the rotation of the valve core 133 and the communication between the first channel 1331 and the liquid storage groove 1323 is maintained, 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 inlet interface 13312 is connected to the liquid storage groove 1323. The liquid interface 13312 is connected to the first liquid outlet 1304. It should be noted that in the process of the liquid outlet interface 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 interface 13331 on the third channel 1333 will also rotate a corresponding angle. At least two different cleaning liquid inlets 1308 corresponding to the main engine water supply pipeline are set on the shell corresponding to the rotation angle range of the cleaning liquid inlet interface 13331, which can realize the addition of different cleaning liquids to the main engine water supply pipeline 171.

[0134] In the scenario where multiple cleaning liquids need to be added to the main engine water supply pipeline 171, this design avoids frequent replacement of cleaning liquids or setting up multiple independent adding devices, greatly improving the flexibility and diversity of adding cleaning liquids and meeting different cleaning needs. In addition, the valve body and the pipeline are highly integrated, the overall structure of the valve body is simple and compact, and the control of the valve body is also relatively simple.

[0135] For the scenario of adding a variety of cleaning liquids to the cleaning pipeline, the above description can be referred to. Accordingly, the second liquid outlet 1304 is connected to the liquid storage groove 1323, and other structures are also flexibly adjusted accordingly, which will not be described in detail.

[0136] See also Fig.19 In one embodiment of the present invention, the shell includes seven cleaning liquid inlets 1308. When the valve core 133 rotates and keeps the first channel 1331 connected to the liquid storage groove 1323, the third channel 1333 connects the cleaning liquid outlet 1309 with the six cleaning liquid inlets 1308 in sequence. This arrangement can realize the addition of six different cleaning liquids to the main engine water supply pipeline 171 within one rotation cycle of the valve core 133, which can meet more cleaning needs of the main engine. The other cleaning liquid inlet 1308 corresponds to the cleaning pipeline, so that while the cleaning liquid is replenished in the main engine water supply pipeline, the cleaning liquid can also be replenished in the cleaning pipeline. Of course, if the cleaning pipeline also needs to be replenished with multiple cleaning liquids, it can also be implemented in the manner of the above embodiment, which will not be repeated here.

[0137] In the present invention, the cleaning liquid extraction device 190 can also be arranged on the pipeline between the cleaning liquid storage chamber and the cleaning liquid inlet 1308. Preferably, in an embodiment of the cleaning base station of the present invention, the cleaning liquid extraction device 190 is arranged on the cleaning liquid addition pipeline 102. The cleaning liquid extraction device 190 is arranged on the cleaning liquid addition pipeline 102, so that the cleaning liquid in multiple cleaning liquid storage chambers can be extracted by one cleaning liquid extraction device 190, and the valve 130 core can be rotated to a suitable position according to actual cleaning needs, so as to accurately extract the required cleaning liquid, which not only reduces the cost but also improves the compactness of the installation.

[0138] In one embodiment of the cleaning base station of the present invention, the cleaning liquid extraction device 190 shown is a peristaltic pump. The peristaltic pump has a unique extrusion-type conveying principle. The cleaning liquid is pushed forward in the pipeline through the rolling extrusion hose of the pump head, which can achieve efficient and stable extraction of the cleaning liquid. Even when the viscosity of the cleaning liquid is high or there is a certain resistance in the pipeline, it can maintain a good extraction effect, ensure the smooth delivery of the cleaning liquid, and provide a continuous and stable supply of cleaning liquid for the cleaning base station. In addition, the structure of the peristaltic pump is relatively simple. Its key component, the hose, is in direct contact with the cleaning liquid during use, while other components such as the pump head do not directly contact the cleaning liquid. This makes the peristaltic pump more convenient to maintain and clean. It only needs to replace the hose regularly, which reduces the maintenance cost and difficulty. At the same time, it also helps to maintain the hygiene and cleanliness of the cleaning liquid extraction device 190, and avoid affecting the cleaning effect of the cleaning liquid due to internal contamination of the device.

[0139] In the present invention, a scale may be provided on the housing, and a pointer may be provided on the valve core 133, and the position of the valve core 133 relative to the housing may be determined by the relationship between the pointer and the scale. Preferably, in consideration of the need for automation, in an embodiment of the cleaning base station of the present 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 installed 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. Through the position detection device 1313, the position information of the valve core 133 can be obtained more accurately, thereby realizing 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 position of the valve core 133, such as switching between multiple cleaning liquids and switching between 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 of the position detection device 1313, thereby ensuring that the cleaning base station can accurately perform various actions according to preset procedures and requirements, thereby improving the control accuracy and reliability of the cleaning base station.

[0140] The position detection device 1313 in the present invention can be any suitable device type that can detect the position of the valve core 133 relative to the shell, such as a magnetic induction position sensor, a Hall position sensor, and a photoelectric position sensor. In one embodiment of the cleaning base station of the present invention, the position detection device 1313 includes a detection element 13131 and a sensing member 13132, the sensing member 13132 is fixedly mounted on the valve core 133, and the detection element 13131 is fixedly mounted on the shell, and corresponds to the position of the sensing member 13132. The coordinated use of the detection element 13131 and the sensing member 13132 makes the position detection process stable and reliable, not easily affected by external interference, and can continuously and accurately provide the control system with feedback information on the position of the valve core 133, providing a strong guarantee for the precise control of the cleaning base station. At the same time, this split installation method of the detection element 13131 and the sensor 13132 allows the detection element 13131 to be installed at a suitable position of the shell and the sensor 13132 to be installed on the valve core 133 during the assembly of the cleaning base station, and the installation process is relatively simple and convenient.

[0141] In one embodiment of the cleaning base station of the present invention, the detection element 13131 includes a Hall sensor, and the induction element 13132 includes a magnetic element. As the detection element 13131, the Hall sensor has the characteristics of high precision and high sensitivity, and can respond quickly and accurately to small changes in the magnetic field. After the magnetic element is used as the induction element 13132 and is fixedly connected to the valve core 133, changes in the magnetic field will occur during the rotation of the valve core 133. The Hall sensor can accurately detect these changes in the magnetic field, thereby achieving high-precision detection of the position of the valve core 133. Even when the rotation angle of the valve core 133 is small or the position change is small, the position information can be accurately captured, providing technical support for the fine control of the cleaning base station.

[0142] In the present invention, the detection element 13131 can be installed on the shell in a variety of ways, for example, it can be snap-connected to the shell, or it can be directly fixed to the shell through a bolt assembly, but it is not limited to this. Preferably, in an embodiment of the cleaning base station of the present invention, the control valve 130 also includes a stopper 1314, and a slot is provided on the shell. The detection element 13131 slides from the opening of the slot and is snapped into the slot. The stopper 1314 is installed to the notch of the slot and stops the detection element 13131. With this structural design, when the detection element 13131 fails or needs to be replaced, it only needs to remove the stopper 1314, and the detection element 13131 can be easily taken out of the slot for replacement or maintenance operations, without the need for complex disassembly of the entire control valve 130 or the shell, which reduces the maintenance cost and difficulty, and improves the maintainability of the cleaning base station.

[0143] The control valve 130 of the present invention may not include the sensor mounting frame 13133, but directly fix the sensor 13132 on the valve core 133. Preferably, in an embodiment of the cleaning base station of the present invention, the control valve 130 also includes a sensor mounting frame 13133, and a mounting groove is provided on the end surface of the valve core 133 close to the detection element 13131. The shape of the mounting groove can be any non-rotational shape, so that the sensor mounting frame 13133 can be inserted and drive the sensor mounting frame 13133 to rotate with the valve core 133. The sensor mounting frame 13133 is inserted into the mounting groove, and the sensor 13132 is installed on the sensor mounting frame 13133. The sensor mounting bracket 13133 can not only provide good support and fixation for the sensor 13132, but also set the sensor 13132 away from the water inlet. When the sensor 13132 needs to be replaced, calibrated or adjusted, the sensor mounting bracket 13133 only needs to be pulled out from the mounting groove to conveniently operate the sensor 13132 without complicated processing or modification of the valve core 133, thereby improving the operability and flexibility of the sensor 13132 and facilitating the smooth maintenance and commissioning of the cleaning base station.

[0144] Although the control valve 130 in the present invention can be manually controlled. Preferably, the cleaning base station has a control system. In one embodiment of the cleaning base station of the present invention, the control valve 130 also includes a driving device 134. The driving device 134 drives each valve core to move synchronously, such as driving the first valve core 133a and the second valve core 133b to rotate synchronously in the shell. The position detection device 1313 and the driving device 134 are both electrically connected to the control system of the cleaning base station. The position detection device 1313 feeds back a signal to the control system. The control system controls the action of the driving device 134 according to the signal of the position detection device 1313, thereby controlling the valve core 130 to rotate or stop rotating. The valve core 133 is driven to rotate in the shell by the driving device 134, so that the rotation of the valve core 133 no longer depends on manual operation or other non-automatic driving methods, thereby realizing 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 accurately control the rotation angle and position of the valve 130 core according to preset programs or control instructions, thereby realizing functions such as automatic switching of cleaning liquid and automatic conversion of cleaning modes, greatly improving the intelligence level and work efficiency of the cleaning base station.

[0145] As long as the movement of the valve core 133 can be achieved, the type of the driving device 134 in the present invention is not limited. Considering that the rotation speed of the valve core 133 is relatively low, please refer to Figure 8 In an embodiment of the cleaning base station of the present invention, the driving 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 driving device 134 adopts a combination of a motor and a reduction mechanism. The motor, as a power source, can provide a stable and controllable power output, and 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 lower speed.

[0146] The type of the deceleration mechanism in the present invention is not limited, for example, it can be a chain drive deceleration structure, a belt drive deceleration structure, a gear deceleration structure or a combination of the above structures. Preferably, please refer to Fig. 20In one embodiment of the cleaning base station of the present invention, the speed reduction mechanism includes a gear assembly of meshing transmission, and 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 on any one of the first valve core 133a, the second valve core 133b, and the third valve core 133c. The gear meshing transmission has the characteristics of high transmission accuracy, stable transmission ratio, and good torque amplification effect. It can accurately transmit the power of the motor to the valve core 133, and realize torque amplification according to the gear ratio, so that the valve core 133 can obtain sufficient torque to drive its rotation under a smaller motor power, meet the requirements of the cleaning base station for the rotation torque of the valve core 133, and improve the transmission efficiency and power utilization effect of the system. It can be understood by those skilled in the art that a transmission gear can also be set between the input gear 1342 and the output gear 1343 according to the need of deceleration.

[0147] In one embodiment of the cleaning base station of the present invention, the shell also includes an outer shell 131 and an inner shell 132, the outer shell 131 is made of a hard material, and the inner shell 132 is made of 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 hard material has high strength and rigidity, can withstand large external pressure and load, and provide stable support and protection for the valve core. The addition of the inner shell 132 allows the shell to have good elasticity and sealing while maintaining a certain strength. It can not only form a good seal between the outer shell 131 and the valve core 133, but also provide conditions for the sealing docking between the valve core 133 and the various interfaces on the shell during the rotation process.

[0148] In one example, the housing includes a first housing and a second housing, and correspondingly, the first housing includes a first inner housing and a first outer housing, and the second housing includes a second inner housing and a second outer housing. In one embodiment of the cleaning base station of the present invention, the housing also includes a first inner housing 1321 and a second inner housing 1322, the first outer housing 1311 and the second outer housing 1312 are both made of a hard material, the first inner housing 1321 and the second inner housing 1322 are made of an elastic material, the first inner housing 1321 is fixed to the inner side of the first outer housing 1311, and is compressed between the first outer housing 1311 and the valve core 133. The second inner housing 1322 is fixed to the inner side of the second outer housing 1312, and is compressed between the second outer housing 1312 and the valve core 133.

[0149] In one embodiment of the cleaning 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, 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, a first column end 1334 is provided at the upper end of the valve core 133, and a second column end 1335 is provided at the lower end of the valve core 133. The first column end 1334 and the second column end 1335 are coaxially arranged, and the first column end 1334 is rotatably mounted on the first outer shell 1311, and the second column end 1335 is rotatably mounted on the second outer shell 1312. The valve core 133 is installed on the outer shell 131 made of hard material, which can ensure the rotation accuracy of the valve core 133, and the elastic inner shell 132 is compressed and arranged between the valve core 133 and the outer shell 131, which provides a guarantee for the sealing connection between the valve core 133 and each interface on the shell.

[0150] It should be noted that under the premise of satisfying the installation of the valve core 133, the outer shell 131 and / or the inner shell 132 can also be an integral structure, and does not have to be divided into the first outer shell 1311 and the second outer shell 1312, or the first inner shell 1321 and the second inner shell 1322.

[0151] In the present invention, the gear can be arranged outside the housing, or between the housings corresponding to the two valve sections.

[0152] See also Figure 8 The housing includes a first housing 1311 and a second housing 1312. The first housing 1311 and the second housing 1312 are sealed and buckled to form a gear box for accommodating the gear assembly. The gear assembly is arranged in the gear box. This structural design can effectively protect the gear assembly, prevent dust, impurities, etc. from entering the gear box to cause wear or jamming of the gear, and also prevent the gear from being subjected to external impact and interference during operation, thereby 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.

[0153] In the present invention, if the first channel 1331, the second channel 1332, and the third channel 1333 are all arranged on one side of the output gear 1343, the output gear 1343 can also be extended out of the shell, so there is no need to arrange a sealing structure between the output gear 1343 and the shell.

[0154] See also Figure 8In this embodiment, the output gear 1343 is arranged in the gear box in the housing, and the first channel 1331, the second channel 1332, and the third channel 1333 are arranged on both sides of the output gear 1343. In order to obtain a better sealing effect, in an embodiment of the cleaning base station of the present invention, the output gear 1343 is arranged between the first inner shell 1321 and the second inner shell 1322, and the end wall of one side of the output gear 1343 is dynamically sealed with the first inner shell 1321 through a first sealing structure, and the end wall of the other side of the output gear 1343 is dynamically sealed with the second inner shell 1322 through a second sealing structure. The example in which the gear is arranged between the housings of the other two valve sections is similar and will not be repeated. This dynamic seal design can effectively prevent the leakage of cleaning liquid, gas and other media from the gap between the output gear 1343 and the inner shell 132 during the rotation of the output gear 1343, and also prevents foreign matter from entering the gear box, thereby ensuring the normal operation of the gear transmission and the clean environment inside the cleaning base station, improving the sealing performance and reliability of the cleaning base station, and ensuring the stable operation of the cleaning base station. However, it should be noted that if the axial seal between the valve core 133 and each inner shell 132 is good, a sealing structure may not be provided between the output gear 1343 and the inner shell 132.

[0155] As long as the dynamic seal between the output gear 1343 and the first inner shell 1321 and the second inner shell 1322 can be achieved, the types of the first sealing structure and the second sealing structure in the present invention are not limited. For example, an O-ring or the like can be set between the first inner shell 1321, the second inner shell 1322 and the end faces of both sides of the output gear 1343, but the present invention is not limited thereto. Referring to Figures and Figures, in an embodiment of the cleaning base station of the present invention, the first sealing structure includes at least one first annular protrusion 13211 arranged on the side of the first inner shell 1321 close to the output gear 1343, the first annular protrusion 13211 is coaxially arranged with the output gear 1343, and the seal is pressed against the end wall of the output gear 1343 close to the first inner shell 1321. And / or. The second sealing structure includes at least one second annular protrusion 13221 disposed on the second inner shell 1322 near the output gear 1343, the second annular protrusion 13221 is coaxially disposed with the output gear 1343, and the seal is tightly pressed against the end wall of the output gear 1343 near the second inner shell 1322. The example in which the gear is disposed between the housings of the other two valve sections is similar and will not be described in detail.

[0156] By making the elastic annular protrusion fit closely with the end wall of the output gear 1343, a good sealing effect can be provided. The protrusion shape of the annular protrusion can be adjusted in size, shape and number as needed to adapt to different sealing requirements and working conditions, thereby improving the reliability and adaptability of the seal. In addition, during long-term use, due to its reasonable force distribution and material properties, this sealing structure can maintain good sealing performance 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.

[0157] See also Figure 3 and Figure 8 In an embodiment of the cleaning base station of the present invention, the liquid inlet 1301 is arranged on the first housing 131a at one end of the first valve core 133a, and a liquid inlet cavity 1324 is arranged in the first housing 131a at a position opposite to the liquid inlet 1301. The cleaning liquid adding device adds cleaning liquid into the liquid inlet cavity 1324 through the cleaning liquid adding pipeline 102. The first channel 1331 includes a liquid inlet interface 13311, which is arranged on the end wall of the first valve core 133a close to the liquid inlet cavity 1324 and communicates with the liquid inlet cavity 1324. This design can ensure that the liquid inlet 1301 is always communicated with the liquid inlet cavity 1324 during the rotation of the first valve core 133a, and further ensure that the cleaning water can smoothly enter the first channel 1331 inside the first valve core 133a from the liquid inlet cavity 1324, which provides good conditions for subsequent liquid distribution and transportation, and helps to improve the operation efficiency of the entire cleaning base station.

[0158] See also Figure 8 and Fig.21 In an embodiment of the cleaning base station of the present invention, the first housing 131a includes a first liquid outlet 1304 and a second liquid outlet 1302, the first channel 1331 includes a liquid outlet interface 13312 connected to the liquid inlet interface 13311, and the liquid outlet interface 13312 is arranged on the outer peripheral wall of the valve core 133, and the valve core 133 has a first infusion connection position ( Fig.10 middle position) and the second infusion connection position ( Fig.11In the middle position), when in the first infusion connection position, the liquid outlet interface 13312 is connected to the first liquid outlet 1304, and the entire control valve 130 is switched to the host infusion state. When in the second infusion connection position, the liquid outlet interface 13312 is connected to the second liquid outlet 1302, and the entire control valve 130 is switched to the cleaning infusion state. The liquid outlet interface 13312 on the valve core 133 is rotated to achieve alternating connection with the first liquid outlet 1304 and the second liquid outlet 1302. This design enables the cleaning base station to flexibly switch the output path of the liquid according to different cleaning needs or working modes, improves the applicability and flexibility of the cleaning base station, and can meet the requirements of various cleaning tasks. At the same time, compared with setting multiple independent valve cores 133 or complex pipeline systems to achieve multi-way liquid outlet, this method of switching by rotating the valve core 133 simplifies the structure, reduces the number and complexity of parts, and reduces production costs and assembly difficulty.

[0159] In an embodiment of the cleaning base station of the present invention, the housing further includes a vent 1303, which is connected to the atmosphere through an exhaust pipe 101. The position where the exhaust pipe 101 is connected to the atmosphere is located above the highest liquid level of the clean water tank. The valve core 133 has a first anti-siphon position (position in the figure) and a second anti-siphon position (position in the figure) during rotation. Fig.14 In the first anti-siphon position, the liquid outlet interface 13312 is connected to the first liquid outlet 1304 and the vent 1303 at the same time, and in the second anti-siphon position, the liquid outlet interface 13312 is connected to the second liquid outlet 1302 and the vent 1303 at the same time. When the liquid output stops, the connection of the vent 1303 can balance the pressure in the pipeline in time, prevent the siphon phenomenon caused by the negative pressure in the pipeline, and improve the safety and reliability of the cleaning base station.

[0160] In an embodiment of the cleaning base station of the present invention, a liquid storage groove 1323 is provided on the shell, and the liquid storage groove 1323 is partially arranged around the outer periphery of the valve core 133, the first liquid outlet 1304 is connected to the liquid storage groove 1323, and the second liquid outlet 1302 is located in the area outside the liquid storage groove 1323. When the first liquid outlet interface 13312 is connected to the liquid storage groove 1323, the first liquid outlet interface 13312 is connected to the first liquid outlet 1304. The design of the liquid storage groove 1323 enhances the compactness of the structure and the simplicity of docking control of the coaxial valve core in the case of multiple cleaning liquids.

[0161] In an embodiment of the cleaning base station of the present invention, the housing includes a first liquid outlet 1304 and a second liquid outlet 1302, and the valve core 133 is connected to the first liquid outlet 1304 and the second liquid outlet 1302. Fig.21Different from the embodiment in the embodiment, the first channel 1331 includes a first liquid outlet interface 13312 and a second liquid outlet interface 13312 connected to the liquid inlet interface 13311. The first liquid outlet interface 13312 and the second liquid outlet interface 13312 are not connected on the outer peripheral wall of the valve core 133, but are independently arranged like the first gas interface and the second gas interface. The first liquid outlet interface 13312 and the second liquid outlet interface 13312 are arranged on the outer peripheral wall of the valve core 133, and a blocking portion is arranged on the inner wall of the shell. Similarly, the valve core 133 has a first infusion connection position and a second infusion connection position during the rotation process. When in the first infusion connection position, the first liquid outlet interface 13312 corresponds to the first liquid outlet 1304, and the blocking portion seals and blocks the second liquid outlet interface 13312. When in the second infusion connection position, the second liquid outlet interface 13312 corresponds to the second liquid outlet 1302, and the blocking portion seals and blocks the first liquid outlet interface 13312.

[0162] The outer wall of the valve core 133 is provided with a first liquid outlet interface 13312 and a second liquid outlet interface 13312. The blocking portion on the inner wall of the shell can seal and block one of the two interfaces during the rotation of the valve core 133, thereby achieving accurate connection and switching between the first liquid outlet 1304 and the second liquid outlet 1302 and the corresponding interface. This design can not only ensure the sealing of the liquid during the switching process, but also improve the accuracy and reliability of liquid switching, so that the cleaning base station can quickly and accurately switch the output path of the liquid according to different work requirements, thereby improving the control accuracy and work efficiency of the cleaning base station.

[0163] In an embodiment of the cleaning base station of the present invention, the housing further comprises a vent 1303, which may be located between the liquid storage groove 1323 and the second liquid outlet 1302. The vent 1303 is connected to the atmosphere through the exhaust pipe 101, and the position where the exhaust pipe 101 is connected to the atmosphere is located above the highest liquid level of the clean water tank. The valve core 133 has a first anti-siphon position ( Fig.13 middle position) and second anti-siphon position ( Fig.14In the first anti-siphon position, the first liquid outlet interface 13312 is connected to the first liquid outlet 1304, and the second liquid outlet interface 13312 is connected to the vent 1303. In the second anti-siphon position, the second liquid outlet interface 13312 is connected to the second liquid outlet 1302, and the first liquid outlet interface 13312 is connected to the vent 1303. During the rotation of the valve core 133, not only the connection switching between the first liquid outlet interface 13312 and the first liquid outlet 1304, and the second liquid outlet interface 13312 and the second liquid outlet 1302 is realized, but also the anti-siphon function is cleverly combined. In the first anti-siphon position, the first liquid outlet interface 13312 is connected to the first liquid outlet 1304, and the second liquid outlet interface 13312 is connected to the vent 1303. In the second anti-siphon position, the second liquid outlet interface 13312 is connected to the second liquid outlet 1302, and the first liquid outlet interface 13312 is connected to the vent 1303. This design can effectively prevent the occurrence of siphoning when the liquid is switched, without the need for an additional anti-siphoning device, thus simplifying the structure, reducing costs, and improving the overall performance and reliability of the system.

[0164] In one embodiment of the cleaning base station of the present invention, the on-off assembly 150 includes a pneumatic valve, the second housing 131b also includes a driving air port 1307, the driving gas inlet of the pneumatic valve is connected to the driving 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 arranged on the outer peripheral wall of the valve core 133, and the valve core 133 has a first gas connection position and a second gas connection position during the rotation of the valve core 133. When the second channel 1332 is connected to the air inlet 1305 and the air outlet 1306 at the first gas connection position, the negative pressure device 140 extracts the gas in the sewage chamber 121 and discharges it through the air outlet 1306. Specifically, when the first gas connection position is in the first gas connection position, one of the first interface 13321 and the second interface 13322 is correspondingly connected to the air inlet 1305, and the other of the first interface 13321 and the second interface 13322 is correspondingly 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 driving air port 1307. This design improves the functional integration of the control valve 130, so that the cleaning base station not only has the liquid distribution and delivery functions, but also integrates the pneumatic control function.

[0165] In an embodiment of the cleaning base station of the present invention, the valve core 133 also has a third gas connection position during the rotation of the valve core 133. When in the third gas connection position, one of the first interface 13321 and the second interface 13322 is correspondingly connected to the driving gas port 1307, and the other of the first interface 13321 and the second interface 13322 is correspondingly connected to the gas outlet 1306. This design enables the control valve 130 to control the opening of the pneumatic valve at the same time.

[0166] In the present invention, the positions of the air inlet 1305, the air outlet 1306, and the driving air port 1307 only need to be connected through the second channel 1332 during the rotation of the valve core 133. In one embodiment of the cleaning base station of the present invention, the second valve core 133b is a rotating body structure, and the air inlet 1305, the air outlet 1306, and the driving air port 1307 are evenly distributed along the circumference of the valve core 133. This arrangement can provide more space for the installation of the pipeline.

[0167] Although the present invention can realize the shut-off control of infusion and exhaust by shutting down the clean water extraction device and the negative pressure device 140, in one embodiment of the cleaning base station of the present invention, 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 liquid inlet 1301 and the liquid outlet and an exhaust blocking state that blocks the air inlet 1305 and the air outlet 1306. This setting can achieve a double blocking effect and improve the reliability of the blocking. However, it can be understood by those skilled in the art that in some other embodiments, there may be only an infusion blocking state or an exhaust blocking state.

The on-off assembly 150 is installed on the sewage pipeline 160, and has a blocking state for blocking the sewage pipeline 160 and a conducting state for conducting the sewage pipeline 160. When the on-off assembly 150 is in the blocking state, the negative pressure device 140 performs an air extraction operation on the sewage chamber 121, so that when the on-off assembly 150 is switched to the conducting state, the sewage pipeline 160 is pumped out through the negative pressure in the sewage chamber 121. 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.

Among them, the second valve core 133b and the third valve core 133c move synchronously. The cleaning base station of the present invention includes a second valve section 130b and a third valve section 130c through the control valve 130, and the opening and closing control of the sewage pipeline 160 and the addition control of the cleaning liquid are realized through the second valve section 130b and the third valve section 130c respectively, without setting multiple control valves 130, which can simplify the installation circuit and save the base station space.
