[0035] In one possible implementation manner, the float valve assembly includes a float and a sealing portion connected to each other, and the float moves under the action of the liquid in the dirt storage container to drive the sealing portion to close or open the air intake port.

[0057] The beneficial technical effects of the present invention are as follows: during the cleaning process of the cleaning element in the cleaning tray, dirt will fall into the cleaning tray, and the cleaning tray assembly drives the dirt in the cleaning tray to gather in the collecting tank through the movement of the scraper, so that both solid impurities and non-solid impurities can be gathered in the collecting tank and transported to the dirt storage container, which greatly reduces the residual dirt in the cleaning tray, reduces the odor caused by the residual dirt in the cleaning tray, reduces the frequency of manual cleaning of the cleaning tray, and improves user satisfaction. By providing a cover plate, the opening size of the collecting tray is reduced, so that the ventilation area between the collecting tray and the outside world is reduced, which helps to form a lower pressure in the collecting tray, thereby enhancing the effect of negative pressure extraction. Negative pressure can be selectively provided to the dust collecting bin and the dirt storage container through the reversing valve mechanism, and there is no need to provide a separate air pump for the dirt storage container, which reduces the power module, simplifies the structure of the cleaning base station, and reduces the cost.

[0085] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to make the technical scheme of the present invention more clear and specific to those skilled in the art, the implementation methods described below are not limited to this. The present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0086] In the present invention, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance; the term "plurality" refers to two or more, unless otherwise clearly defined. The terms "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0087] After the automatic cleaning device completes the mopping operation, it returns to the cleaning base station. The cleaning element can be a mop plate. During the cleaning process of the cleaning element, the cleaning base station is provided with a raised scraping strip to interfere with the cleaning element, so as to remove the dirt on the cleaning element and gather the dirt in the sewage tank. The dirt remaining in the tank is not cleaned for a long time or is not cleaned thoroughly, which is easy to produce odor, and there is also the problem of bacterial growth, which leads to secondary pollution of the cleaning element. Generally, the sewage tank needs to be cleaned regularly, and the sewage tank is removed from the base mechanism for manual cleaning. Frequent cleaning is time-consuming and laborious, which affects the user experience. In the process of cleaning the cleaning element, some cleaning base stations add a sewage tank to suck the sewage generated by cleaning the cleaning element into the sewage tank. Since the cleaning element is generally cleaned by rotation, the dirt is easy to gather in the edge area of ​​the sewage tank under the action of centrifugal force. The traditional method of connecting the sewage pipe with the sewage tank to extract the dirt is easy to leave a large amount of solid impurities in the tank, and frequent cleaning is still required, which cannot solve the problem of residual solid impurities in the tank.

[0088] The dirt may include liquid impurities and solid impurities, namely, dirty liquid, hair, solid residues and the like.

[0089] The first aspect of the present invention, as Figure 3-Figure 13 As shown, a cleaning disc assembly 1 is provided, comprising a cleaning disc body, a scraper 12 and a cover plate 14. The cleaning disc body is provided with a cleaning groove 11 and a collecting groove 13 opened on the bottom wall of the cleaning groove 11. The cover plate 14 covers a part of the groove opening of the collecting groove 13 to form an opening connected to the cleaning groove 11. The scraper 12 is movably arranged on the cleaning disc body. At least a part of the opening of the collecting groove 13 is located on the moving track of the scraper 12. The scraper 12 is used to drive the dirt in the cleaning groove 11 to move into the collecting groove 13 through the opening.

[0090] The cleaning disc assembly 1 provided in the embodiment of the present disclosure drives the dirt in the cleaning tank 11 to gather in the collecting tank 13 through the movement of the scraper 12, so that both solid impurities and non-solid impurities can be gathered in the collecting tank 13 and transported to the dirt storage container 31, thereby greatly reducing the residual dirt in the cleaning disc, reducing the situation of residual dirt in the cleaning disc generating odor, reducing the frequency of manual cleaning of the cleaning disc, and improving user satisfaction. Negative pressure can be selectively provided to the dust collecting bin 9 and the dirt storage container 31 through the reversing valve mechanism 4, and there is no need to provide a separate air pump for the dirt storage container 31, thereby reducing the power module, simplifying the structure of the cleaning base station, and reducing the cost.

[0091] It can be understood that the scraper 12 moves in close contact with the cleaning tank 11, and during the movement, it drives the dirt in the cleaning tank 11 to move to the opening position of the collecting tank 13, and the dirt falls into the collecting tank 13 through the opening, which can greatly reduce the dirt exposed in the cleaning tank 11 and reduce the generation of odor and bacterial growth.

[0092] The dirt in the open cleaning tank 11 is collected into a collecting tank 13 with a smaller space by the scraper 12, which is convenient for extracting the dirt, and the solid impurities and liquid impurities in the collecting tank 13 are mixed together, which is convenient for the solid impurities to be extracted along with the liquid impurities.

[0093] The cleaning tray assembly 1 provided in the embodiment of the present disclosure reduces the opening size of the collection tank 13 by setting the cover plate 14, so that the ventilation area between the collection tank 13 and the outside is reduced, thereby enhancing the effect of negative pressure extraction. The cover plate 14 is set on the collection tank 13 and blocks a part of the slot. After the opening size is reduced, it is more difficult for external air to enter the collection tank 13, so that the pressure in the collection tank 13 is further reduced, which helps the liquid to be sucked out more smoothly. Under the condition of a certain negative pressure, the opening size is reduced, resulting in an increase in the flow rate of the liquid through the collection tank 13, thereby increasing the suction flow rate, helping to empty the dirt in the collection tank 13 more quickly, reducing the residual amount in the collection tank 13, and reducing the odor and bacterial growth.

[0094] It is understandable that the position and size of the opening can be adjusted by adjusting the size and shape of the cover plate 14 to meet different suction requirements.

[0095] In one possible implementation, Figure 3-Figure 5 As shown, at least one scraping member 12 is provided in the cleaning tank 11. Figure 10-12 As shown, the spatial contour of the cleaning tank 11 is adapted to the movement trajectory of the scraper 12 .

[0096] In this embodiment, a scraping member 12 is used as an example. When the scraping member 12 is rotatably connected to the cleaning disc body, the space inside the cleaning tank 11 can be approximately circular.

[0097] In this embodiment, two scraping members 12 are used as an example. When the scraping members 12 are rotatably connected to the cleaning disc body, the space inside the cleaning tank 11 can be approximately in the shape of an ∞.

[0098] It can be understood that the number of scraping members 12 can be one, two, three or other integers, and the spatial contour within the cleaning tank 11 is adapted to the number, position and movement trajectory of the scraping members 12. At the same time, the spatial contour within the cleaning tank 11 is also adapted to the number, position and size of the cleaning elements, so that the cleaning tank 11 can carry the dirt dropped from the cleaning elements, and the scraping member 12 can maintain contact with the tank wall of the cleaning tank 11 during movement, so as to drive the dirt adhered to the tank wall to move with the scraping member 12 until it falls into the collection tank 13 through the opening.

[0099] Among them, Figure 3 As shown, the cleaning tank 11 is provided with a scraping strip 18 for interfering with the rotating cleaning element to remove dirt on the cleaning element so that the dirt falls and gathers in the cleaning tank 11. The scraping strip 18 can be arranged above the scraping member 12 to avoid interference between the scraping strip 18 and the scraping member 12.

[0100] In one possible implementation, Figure 10-12 As shown, the cleaning tank 11 includes at least two connected cleaning chambers, and a scraping member 12 is disposed in each cleaning chamber.

[0101] It can be understood that the cleaning tank 11 includes cleaning chambers arranged corresponding to the cleaning elements. When there are at least two cleaning elements, the number of cleaning chambers corresponds to the number of cleaning elements, and the number of scraping members 12 corresponds to the number of cleaning chambers, so that there is a cleaning chamber under each cleaning element for collecting dirt falling from the cleaning element, and each cleaning chamber is provided with a scraping member 12 for cleaning the dirt on the inner wall of the cleaning chamber.

[0102] In one possible implementation, Figure 4 As shown, there are two cleaning chambers and two scraping members 12 , and at least a portion of the opening of the collecting groove 13 is located between the two cleaning chambers.

[0103] In this embodiment, the number of cleaning chambers and scraping members 12 is two as an example. The collecting groove 13 is set between the two cleaning chambers so that the opening of the collecting groove 13 is located between the two cleaning chambers, and the moving trajectory of one scraping member 12 overlaps with the opening of the collecting groove 13, and the moving trajectory of the other scraping member 12 also overlaps with the opening of the collecting groove 13, so that the scraping member 12 can drive the dirt to the opening during its movement.

[0104] In one embodiment, the collecting tank 13 includes at least two interconnected cleaning chambers, such as Fig.10 and Fig.11As shown, the cleaning ranges of two adjacent scraping members 12 have at least a partially overlapping area, and the overlapping area is located between the two scraping members 12 , and the dirt remaining after cleaning by one scraping member 12 is cleaned by the other adjacent scraping member 12 .

[0105] It is understandable that the plurality of scraping members 12 may rotate in the same direction or in different directions. Fig.10 As shown, the plurality of scraping members 12 rotate in the same direction. Fig.11 and Fig.12 As shown, the plurality of scraping members 12 rotate in non-co-directions. The scraping members 12 can rotate toward the positive direction of the opening so that dirt enters from the positive direction of the opening.

[0106] It is understandable that the plurality of scraping members 12 may rotate synchronously or asynchronously. Fig.10 and Fig.12 As shown, the plurality of scraping members 12 rotate synchronously. Fig.11 As shown, the plurality of scraping members 12 rotate asynchronously.

[0107] like Fig.11 As shown, this embodiment takes the case where the number of cleaning chambers and scraping members 12 are both two, the cleaning ranges of the two adjacent scraping members 12 have at least a partial overlapping area, and the two scraping members 12 rotate in opposite directions asynchronously as an example, that is, the two scraping members 12 pass through the overlapping area and the opening of the collection groove 13 in an alternating manner, so that one scraping member 12 can clean the dirt thrown out by the other scraping member 12, which can greatly reduce the dirt missed by the scraping member 12 and has a good cleaning effect.

[0108] In one embodiment, the collecting tank 13 includes at least two interconnected cleaning chambers, such as Fig.12 As shown, there is no overlapping area between the cleaning ranges of two adjacent scraping members 12 .

[0109] like Fig.12 As shown, this embodiment takes the case where the number of cleaning cavities and scraping members 12 is two, the cleaning ranges of two adjacent scraping members 12 have no overlapping areas, and the two scraping members 12 rotate synchronously in opposite directions as an example, that is, the two scraping members 12 are approximately mirror images during the rotation process, and when the two scraping members 12 rotate until the free ends are opposite to each other, they are located on the same straight line, and the two scraping members 12 respectively drive the dirt to gather in front of the opening and move toward the front of the opening, so that the cleaning effect is good.

[0110] In one possible implementation, Figure 10-12 As shown, the scraper 12 contacts the bottom wall of the cleaning tank 11 during the movement; and / or the scraper 12 contacts the inner side wall of the cleaning tank 11 during the movement.

[0111] It is understandable that the shape of the scraper 12 is adapted to the wall of the cleaning tank 11 so that the scraper 12 can abut against the bottom and / or side wall of the cleaning tank 11 during movement to remove dirt on the wall and move the dirt with the scraper 12.

[0112] In one possible implementation, Fig. 9 As shown, the scraper 12 includes a connecting end and a free end. The connecting end is connected to the cleaning disc body. The scraper 12 includes an abutting portion 121. The abutting portion 121 is elastic and is used to abut against the wall of the cleaning tank 11.

[0113] It can be understood that the abutment portion 121 is located at the free end and / or bottom end of the scraper 12, that is, the position where the scraper 12 is used to abut against the groove wall of the cleaning groove 11, that is, the hanging bar is arranged to fit the shape of the groove wall of the cleaning groove 11. The number of hanging bars is at least one, and can also be two or other integers of more than two. Multiple hanging bars can clean the groove wall of the cleaning groove 11 multiple times during the rotation of the scraper 12.

[0114] The contact part 121 can be made of elastic materials such as rubber and silicone. When the scraper 12 contacts the wall of the cleaning tank 11, the contact part 121 can be in full contact with the wall, thereby improving the cleaning effect and fully removing the residual sewage on the wall. When the contact part 121 contacts the solid impurities, it applies thrust to the solid impurities. When the solid impurities are stubborn, the contact part 121 can be deformed to pass through the solid impurities without affecting the normal operation of the scraper 12. The scraper 12 can be partially made of elastic material, or the whole can be made of elastic material.

[0115] In one possible implementation, Fig. 9 As shown, the width of the scraper 12 decreases gradually from the connecting end to the free end, so that the front side wall of the scraper 12 along the rotation direction forms a guide surface 122 .

[0116] It can be understood that by setting a guide surface 122 on the front side wall of the scraper 12, the guide surface 122 is an inclined plane or an inclined arc surface, and the dirt in the cleaning groove 11 close to the connection end of the scraper 12 is guided along the guide surface 122 toward the free end of the scraper 12, so that the dirt can move to the periphery of the cleaning area of ​​the scraper 12, and then be swept into the opening by the scraper 12.

[0117] In one possible implementation, Figure 7 As shown, the collecting tank 13 is opened on the bottom wall of the cleaning tank 11. The collecting tank 13 includes a collecting cavity with an opening. The dirt in the cleaning tank 11 enters the collecting cavity through the opening.

[0118] The collecting tank 13 can be an integrally formed structure or a split structure. Dirt enters the collecting chamber through the opening. When the dirt is extracted, the flow rate of the dirt in the collecting chamber is accelerated due to the small space in the collecting chamber. The liquid impurities and solid impurity mixture in the collecting chamber are easy to be extracted, which greatly improves the efficiency and effect of sewage extraction.

[0119] In one possible implementation, Figure 3-Figure 5 As shown, there is a height difference between the collecting tank 13 and the cleaning tank 11 , and the cover plate 14 and the collecting tank 13 enclose a collecting chamber with an opening.

[0120] When the collecting tank 13 is a split structure, the cleaning disc assembly 1 also includes a cover plate 14, and the cover plate 14 and the collecting tank 13 are enclosed to form a collecting cavity, and the cover plate 14 covers a portion of the slot opening of the collecting tank 13, and the dirt in the cleaning tank 11 enters the collecting cavity through the opening not covered by the cover plate 14.

[0121] The cover plate 14 is detachably connected to the cleaning disc body, that is, the cover plate 14 is detachably connected to the collecting tank 13, so that the cover plate 14 can be easily removed from the cleaning disc body for cleaning, and the collecting tank 13 is exposed for easy cleaning, which is beneficial to improve the thoroughness of cleaning the cleaning disc assembly 1 and improve the cleaning experience. At the same time, when the opening is blocked, the cover plate 14 can be removed for dredging and maintenance, reducing the probability of failure.

[0122] Among them, Figure 5 As shown, the cover plate 14 and the collecting tank 13 can be magnetically connected via a magnetic member 17, a first magnetic member is provided on the collecting tank 13, a corresponding second magnetic member is provided on the cover plate 14, or the cover plate 14 itself includes magnetic material, and the cover plate 14 and the collecting tank 13 can be magnetically connected together when their corresponding positions are close to each other, and the cover plate 14 can be removed by overcoming the magnetic force during disassembly. Compared with traditional bolt connections, the magnetic connection has a simpler structure, lower cost, and easier operation, reduces the possibility of harboring dirt and grime, facilitates the installation and removal of the cover plate 14 for cleaning, and improves installation and removal efficiency.

[0123] The shape of the cover plate 14 can be adapted to the cleaning range of the scraper 12. The cover plate 14 is located outside the cleaning range of the scraper 12 so that the cover plate 14 does not affect the scraper 12, thereby preventing dirt from gathering at the cover plate 14. When the scraper 12 moves, when the free end of the scraper 12 moves to the opening position, the free end is located directly above the opening, so that the dirt moving with the scraper 12 can enter the collection tank 13 through the opening.

[0124] In one possible implementation, Figure 7As shown, a dirt suction pipe opening 16 is provided on the side wall of the collecting tank 13, the first end of the dirt suction pipe opening 16 is connected to the collecting cavity, and the second end of the dirt suction pipe opening 16 extends out of the collecting cavity. The dirt in the collecting tank 13 is sucked out through the dirt suction pipe opening 16, so that the cleaning tank 11 can continue to contain the dirt, so as to achieve continuous cleaning of the cleaning element, which is beneficial to improving the cleaning effect, and at the same time, it can prevent the dirt in the cleaning tank 11 from overflowing due to failure to be discharged in time and causing secondary pollution.

[0125] In one possible implementation, Figure 5 As shown, an elastic sealing gasket 15 is provided on the outer peripheral wall of the sewage suction pipe opening 16. The sealing gasket 15 is sleeved on the sewage suction pipe opening 16. The sealing gasket 15 can be tower-shaped. The sewage suction pipe 81 is connected to the sewage suction pipe opening 16 through the sealing gasket 15. The sealing gasket 15 is used to seal the sewage suction pipe 81 and the sewage suction pipe opening 16 to prevent leakage at the connection point from causing secondary pollution.

[0126] In one possible implementation, Figure 7 and Figure 8 As shown, the collecting chamber includes a dirt collecting area 131 and a dirt suction area 132 which are connected. The dirt suction pipe port 16 is located at a height higher than that of the dirt collecting area 131. The dirt suction area 132 extends obliquely to connect the dirt collecting area 131 with the dirt suction pipe port 16. There is a height difference between the dirt collecting area 131 and the dirt suction pipe port 16. The dirt suction pipe port 16 is higher than the dirt collecting area 131. When the cleaning disc assembly 1 is tilted and taken out, a small amount of residual dirt in the cleaning tank 11 is gathered in the dirt collecting area 131 to prevent it from flowing out of the dirt suction pipe port 16 and causing secondary pollution to the base.

[0127] In one possible implementation, Figure 7 and Figure 8 As shown, the flow cross-sectional area of ​​the sewage suction area 132 decreases in the direction from the sewage collection area 131 to the sewage suction pipe port 16. The sewage suction area 132 is a trumpet shape that is wide at the front and narrow at the back, and the side wall of the sewage suction area 132 is an inclined arc surface or an inclined plane, so that the dirt is gathered toward the position of the sewage suction pipe port 16 along the flow direction, so as to facilitate the removal of the dirt.

[0128] In one possible implementation, Figure 5 and Figure 6 As shown, the cleaning disc assembly 1 also includes a liquid level detection mechanism 7, which is arranged in the cleaning tank 11 and is used to detect the liquid level height in the cleaning tank 11. It can determine whether the liquid level in the cleaning tank 11 is within a reasonable range to prevent the liquid level in the cleaning tank 11 from being too high and causing dirt to overflow from the outside of the cleaning tank 11 to cause secondary pollution, which is beneficial to improving safety and cleanliness of use.

[0129] Specifically, the liquid level detection mechanism 7 is a liquid level sensor, and may also be other structures that meet the requirements.

[0130] Among them, Figure 5 and Figure 6 As shown, the liquid level detection mechanism 7 includes a first conductive member 71 and a second conductive member 72 . When the liquid level in the cleaning tank 11 reaches the position where the first conductive member 71 and the second conductive member 72 are located, an electrical connection is formed between the first conductive member 71 and the second conductive member 72 .

[0131] Among them, the first conductive member 71 includes a first conductive rubber and a first conductive sheet in contact with each other, the second conductive member 72 includes a second conductive rubber and a second conductive sheet in contact with each other, the first conductive rubber and the second conductive sheet are arranged in the cleaning tank 11, the first conductive sheet and the second conductive sheet are arranged outside the cleaning tank 11, and the first conductive sheet and the second conductive sheet can be arranged on the base mechanism 2. When the liquid level in the cleaning tank 11 exceeds a reasonable range, the liquid level reaches the position of the first conductive rubber and the second conductive rubber, and the first conductive member 71 and the second conductive member 72 form a closed electrical circuit, and then detect that the liquid level exceeds the reasonable range, and an alarm is issued for the abnormal liquid level, so as to facilitate timely cleaning of the cleaning tank 11.

[0132] The second aspect of the present invention, as Figure 1-Figure 21 As shown, a cleaning base station 100 is provided, comprising the cleaning disc assembly 1 of any one of the first aspects.

[0133] In one possible implementation, Figure 3 and Figure 4 As shown, the cleaning base station 100 further includes a driving mechanism 6, which is connected to the scraping member 12 to drive the scraping member 12 to move on the cleaning disc body.

[0134] The driving mechanism 6 drives the scraper 12 to move on the cleaning disc body. The movement mode may be translational movement, rotational movement, etc., so that the scraper 12 keeps contact with the wall of the cleaning tank 11 during the movement, so as to scrape off the dirt on the wall.

[0135] In one possible implementation, Figure 6 As shown, the driving mechanism 6 includes a driving motor 61 and a transmission mechanism 62. The driving motor 61 is connected to the connecting end of the scraping member 12 through the transmission mechanism 62 to drive the scraping member 12 to rotate around the connecting end.

[0136] like Figure 6 As shown, the driving mechanism 6 is arranged on the base mechanism 2, and the output end of the driving mechanism 6 passes through the cleaning disk body and is connected to the transmission mechanism 62. The number and position of the output end of the transmission mechanism 62 are arranged corresponding to the scraper 12, and the connecting end of the scraper 12 is connected to the output end of the transmission mechanism 62. The scraper 12 can be detachably connected to the output end of the transmission mechanism 62 by one of a threaded structure, a clamping structure, and a mortise and tenon structure.

[0137] Among them, the scraper 12 can be detachably connected to the output end of the transmission mechanism 62 through a snap-fit ​​structure. For example, one of the scraper 12 and the transmission mechanism 62 is provided with a buckle, and the other is provided with a slot. When the scraper 12 and the transmission mechanism 62 are connected, the buckle is locked in the slot, and when the scraper 12 and the transmission mechanism 62 are separated, the buckle is separated from the slot.

[0138] Furthermore, a seal, such as a sealing ring, may be provided between the scraper 12 and the output end of the transmission mechanism 62 to prevent sewage from leaking through the gap between the scraper 12 and the transmission mechanism 62 and to prevent sewage from flowing into the transmission mechanism 62 and damaging the equipment.

[0139] like Fig.13 As shown, in this embodiment, the number of scraping members 12 is two, and the driving mechanism 6 includes a driving motor 61, and the transmission mechanism 62 includes a gear set. The output end of the driving motor 61 is connected to the gear set, and the gear set includes a plurality of meshing gears for driving the scraping member 12 to rotate.

[0140] Among them, Fig.13 As shown, the gear set includes a coaxially arranged turbine and a first gear, a coaxially arranged second gear and a third gear, a fourth gear, a fifth gear, a sixth gear and a seventh gear, the fifth gear is placed directly below a cleaning chamber, and the seventh gear is placed directly below another cleaning chamber. The output shaft of the drive motor 61 is connected to a worm and meshes with the turbine, the turbine drives the first gear to rotate synchronously to form a reducer, the first gear is meshed with the second gear, the second gear drives the third gear to rotate synchronously, the third gear is meshed with the fourth gear, the fourth gear is meshed with the fifth gear, and the sixth gear is placed between the fifth gear and the seventh gear and meshes with both of them respectively. Among them, when the fifth gear and the seventh gear rotate in the same direction, there can be a sixth gear between the fifth gear and the seventh gear, and when the fifth gear and the seventh gear rotate in the opposite direction, there can be two meshed sixth gears between the fifth gear and the seventh gear. Among them, a notch is opened on the cleaning disc body, the notch is located in the center of the cleaning chamber, a connecting piece is coaxially arranged on the fifth gear, and a connecting piece is coaxially arranged on the seventh gear. The connecting piece is inserted into the notch to connect with the scraping piece 12, driving the scraping piece 12 to rotate in the cleaning chamber.

[0141] In one possible implementation, Figure 1 and Figure 2As shown, the cleaning base station 100 also includes a sewage collection mechanism 3, a dust collecting bin 9, a conveying pipe assembly 8, a reversing valve mechanism 4 and a negative pressure system 5; the first end of the conveying pipe assembly 8 is connected to the collecting tank 13, and the second end of the conveying pipe is connected to the sewage collection mechanism 3, so as to transport the dirt in the collecting tank 13 to the sewage collection mechanism 3; the first end of the reversing valve mechanism 4 is connected to the dust collecting bin 9, the second end of the reversing valve mechanism 4 is connected to the negative pressure system 5, and the third end of the reversing valve mechanism 4 is connected to the sewage collection mechanism 3; the negative pressure system 5 can be selectively connected to the sewage collection mechanism 3 or the dust collecting bin 9 through the reversing valve mechanism 4.

[0142] It is understandable that the first end of the conveying pipe assembly 8 is connected to the second end to extract the dirt in the collection tank 13 and transport it to the sewage collection mechanism 3. The negative pressure system 5 can be an integrated fan assembly and other components that can achieve negative pressure through a mechanical mobile phone. The integrated fan assembly may include components such as an exhaust fan and a filter. Among them, the reversing valve mechanism 4 is connected to the negative pressure system 5, and can be selectively connected to one of the dust collecting bin 9 and the sewage collection mechanism 3 to select the dust collecting bin 9 or the sewage collection mechanism 3 to be in a negative pressure state. By setting an integrated fan assembly and a reversing valve assembly for use, the effect of pumping negative pressure on the dust collecting bin 9 and the sewage collection mechanism 3 can be achieved, reducing the composition of the cleaning base station power module, reducing a group of dust collecting fan assemblies and air pumps, reducing the weight of the cleaning base station, and reducing costs.

[0143] In one possible implementation, Figure 2 As shown, the reversing valve mechanism 4 includes a first working condition and a second working condition. When the reversing valve mechanism 4 is in the first working condition, the first end of the reversing valve mechanism 4 is connected to the second end to connect the negative pressure system 5 with the dust collecting bin 9; when the reversing valve mechanism 4 is in the second working condition, the third end of the reversing valve mechanism 4 is connected to the second end to connect the negative pressure system 5 with the sewage collection mechanism 3.

[0144] Among them, when the reversing valve mechanism 4 is in the first working condition, the negative pressure system 5 is connected with the dust collecting bin 9 to extract the gas in the dust collecting bin 9, so that the dust collecting bin 9 is in a negative pressure state; when the reversing valve mechanism 4 is in the second working condition, the negative pressure system 5 is connected with the sewage collecting mechanism 3 to extract the gas in the sewage collecting mechanism 3, so that the sewage collecting mechanism 3 is in a negative pressure state.

[0145] In one possible implementation, Fig.14 and Fig.15 As shown, the sewage collection mechanism 3 includes a sewage storage container 31 and a sewage discharge port 34 and an air intake port 32 arranged in the sewage storage container 31 .

[0146] It is understandable that the heights of the sewage outlet 34 and the air inlet 32 ​​are both located above the liquid level in the sewage storage container 31 to prevent dirt from entering the air inlet 32 ​​and causing pollution, and to prevent dirt from entering the sewage outlet 34 and causing backflow.

[0147] In one embodiment, a water vapor filter 33 is provided on the air inlet 32 ​​to form a stopper for water vapor and impurities.

[0148] Among them, a water vapor filter 33 is provided on the air inlet 32. The water vapor filter 33 can allow gas to pass through, block water vapor and impurities, remove a large amount of water and impurities in the gas, prevent dirty water vapor from entering the reversing valve mechanism 4 and the negative pressure system 5 through the air inlet 32, and protect the normal operation of the equipment. The water vapor filter 33 can well protect the negative pressure system 5, extend the service life of the equipment, and improve production efficiency and stability of the equipment. Specifically, the water vapor filter 33 can be a fiber material or other physical adsorption material to separate water. The gas is filtered through the water vapor filter 33. The surface of the fiber material is hydrophobic, which can separate water vapor in the gas and filter out particulate matter in the gas.

[0149] In one possible implementation, Fig.14 and Fig.15 As shown, the sewage collection mechanism 3 further includes a float valve assembly 35 , which can move with the change of the liquid level in the sewage storage container 31 to close or open the air suction port 32 to adjust the air pressure in the sewage storage container 31 .

[0150] Among them, Fig.14 and Fig.15 As shown, the float valve assembly 35 includes a float 351 and a sealing portion 352 connected to each other. The float 351 moves under the action of the liquid in the dirt storage container 31 to drive the sealing portion 352 to close or open the air inlet 32.

[0151] It can be understood that by arranging the float valve assembly 35 in the sewage storage container 31 to detect the liquid level in the sewage storage container 31, the float 351 floats under the action of the liquid, and the float 351 is connected to the sealing part 352. When the float 351 contacts the liquid and moves upward as the liquid level rises, the sealing part 352 moves downward accordingly as the float 351 moves upward. The preset liquid level is below the air intake port 32 and the sewage outlet 34. When the liquid level in the sewage storage container 31 exceeds the preset liquid level, the sealing part 352 presses and closes the air intake port 32. When a water vapor filter 33 is provided on the air intake port 32, the water vapor filter 33 is sealed to seal the air intake port 32. When the liquid level in the sewage storage container 31 does not reach the preset liquid level, the sealing part 352 separates from the air intake port 32 to open the air intake port 32.

[0152] The float valve assembly 35 is provided to detect the liquid level in the dirt storage container 31, and when the liquid level reaches a preset level, the air intake port 32 is closed, thereby adjusting the air pressure in the dirt storage container 31, stopping the extraction of dirt from the collection tank 13, and preventing excessive dirt from overflowing from the dirt storage container 31, or excessive dirt from entering the negative pressure system 5 through the air intake port 32, so as to facilitate timely cleaning of the dirt storage container 31.

[0153] In one embodiment, the sewage collection mechanism 3 further includes a filter screen, which is placed in the sewage storage container 31 and is used to separate liquid impurities and solid impurities in the sewage in the sewage storage container 31. The filter screen and the sewage storage container 31 are detachably connected.

[0154] Since the solid impurities and liquid impurities in the cleaning disk assembly 1 are all collected and collected in the dirt storage container 31, the solid impurities are easy to clog the sewer or toilet when the user pours out the dirt in the dirt storage container 31. In view of this, a detachable filter net is provided in the dirt storage container 31, and the filter net is located below the sewage outlet 34 to separate the solid impurities and liquid impurities in the dirt storage container 31. The filter net can be removed from the dirt storage container 31, which is convenient for cleaning the solid impurities on the filter net separately, which is conducive to improving the thoroughness of cleaning the dirt storage container 31, so as to prevent the solid impurities from being deposited at the bottom of the dirt storage container 31.

[0155] The filter screen can be located at or above the preset liquid level of the sewage storage container 31. The size and installation position of the filter screen can be sufficient to fully bear the dirt discharged from the sewage outlet 34. The shape of the filter screen can be adapted to the cross section of the sewage storage container 31. The filter screen can be located in an area outside the float valve assembly 35, so that the filter screen can be removed separately.

[0156] Furthermore, the filter screen and the dirt storage container 31 can be detachably connected by a snap-fit ​​structure, a limiting structure, a threaded structure, a mortise and tenon structure, a magnetic structure, etc. The edge area of ​​the filter screen can be provided with an upwardly extending enclosure, which can be closed or provided with a gap along the circumferential direction to limit the solid impurities on the filter screen, so that the dirt can be gathered on the filter screen when it is taken out.

[0157] In one possible implementation, Figure 2 As shown, the conveying pipe assembly 8 includes a sewage suction pipe 81 and an air suction pipe 82, the first end of the sewage suction pipe 81 is connected to the collecting tank 13, the second end of the sewage suction pipe 81 is connected to the sewage outlet 34, the first end of the air suction pipe 82 is connected to the reversing valve mechanism 4, and the second end of the air suction pipe 82 is connected to the air intake port 32.

[0158] The interior of the sewage storage container 31 is a relatively closed space. The collection tank 13 and the sewage storage container 31 are connected through the sewage suction pipe 81, and the reversing valve mechanism 4 and the sewage storage container 31 are connected through the air suction pipe 82. The negative pressure system 5 extracts the gas in the sewage storage container 31 through the air suction pipe 82 through the reversing valve mechanism 4, so that the sewage storage container 31 is in a negative pressure state, and then the dirt in the collection tank 13 is extracted and transported to the sewage storage container 31 through the sewage suction pipe 81.

[0159] In one possible implementation, Figure 16-18 As shown, the reversing valve mechanism 4 includes a reversing valve body and a steering motor 43. The reversing valve body includes a valve body 41 and a valve core 42. The valve body 41 includes a first port 411, a second port 412 and a third port 413 that are connected to each other. The valve core 42 is arranged in the valve body 41 and is movably connected to the valve body 41. The valve core 42 includes a first position and a second position. When the valve core 42 is in the first position, the first port 411 is connected to the second port 412. When the valve core 42 is in the second position, the first port 411 is connected to the third port 413. The output end of the steering motor 43 is connected to the valve core 42 for adjusting the valve core 42 to switch between the first position and the second position.

[0160] It can be understood that when the valve core 42 is in the first position, a stopper is formed on the third port 413, so that the first port 411 is connected to the second port 412, and then the negative pressure system 5 and the dust collecting bin 9 are connected, so as to achieve the effect of extracting the gas in the dust collecting bin 9; when the valve core 42 is in the first position, a stopper is formed on the second port 412, so that the first port 411 is connected to the third port 413, and then the negative pressure system 5 and the sewage collecting mechanism 3 are connected, so as to achieve the effect of extracting the gas in the sewage storage container 31.

[0161] The output end of the steering motor 43 is disposed through the valve body 41 and connected to the valve core 42 to drive the valve core 42 to move and switch between the first position and the second position.

[0162] In one possible implementation, Fig.18 As shown, the reversing valve mechanism 4 further includes a photoelectric switch 44 , which is arranged opposite to the valve core 42 . There are at least two photoelectric switches 44 for obtaining the in-position information of the valve core 42 at the first position and the second position.

[0163] Among them, one photoelectric switch 44 is set at the position corresponding to the valve core 42 in the first position, so as to obtain the in-place information of the valve core 42 in the first position, and the other photoelectric switch 44 is set at the position corresponding to the valve core 42 in the second position, so as to obtain the in-place information of the valve core 42 in the second position, and the photoelectric switch 44 is used to feedback whether the valve core 42 has moved into place.

[0164] In one possible implementation, Fig.18 As shown, the reversing valve mechanism 4 also includes an air pressure detection mechanism 46, which is connected to the reversing valve body through the reversing valve base 45, and the air pressure detection mechanism 46 is connected to the suction pipe 82 of the delivery pipe assembly 8. When the reversing valve mechanism 4 is in the second working condition and the negative pressure in the reversing valve body exceeds the set range, the air pressure detection mechanism 46 is opened to connect the reversing valve body with the outside of the reversing valve body.

[0165] The reversing valve base 45 is arranged on the valve body 41, and the air pressure detection mechanism 46 is connected to the reversing valve body through the reversing valve base 45. When the intake pipe is blocked, the negative pressure in the reversing valve exceeds the set range, and the air pressure detection mechanism 46 automatically opens to adjust the air pressure of the reversing valve body and the intake pipe to prevent malfunctions caused by excessive negative pressure.

[0166] Among them, the air pressure detection mechanism 46 also includes a pressure regulating hole, an elastic member and a sealing member. The pressure regulating hole is respectively connected to the inside of the reversing valve body and the outside of the reversing valve body. The first end of the elastic member is relatively fixed to the position of the pressure regulating hole, and the second end of the elastic member is connected to the sealing member. The elastic member is used to apply an elastic force to press the sealing member to seal on the pressure regulating hole. When the air pressure in the reversing valve body is less than the set value, the sealing member overcomes the elastic force and moves away from the pressure regulating hole and opens the pressure regulating hole, so that the reversing valve body and the suction pipe 82 are connected to the outside of the reversing valve body.

[0167] It can be understood that the valve body 41 is provided with an air leakage hole, which is located between the third port 413 and the valve core 42, and the seal is in contact with the pressure regulating hole through an elastic member, and the two ends of the elastic member are respectively connected to the seal and the inner wall of the air pressure detection mechanism 46, and the elastic member is used to apply an elastic force to the seal to make the seal and the pressure regulating hole abut. When the negative pressure in the reversing valve body is too large, the seal is moved in the direction away from the pressure regulating hole by the suction force, so that a gap for air flow is formed between the seal and the pressure regulating hole, so that the pressure regulating hole is connected to the inside of the reversing valve body through the air leakage hole, so that the air pressure in the reversing valve body and the air pressure in the suction pipe are increased. The air pressure in the reversing valve body gradually increases, the elastic member is reset, and the seal moves in the direction close to the pressure regulating hole under the action of the elastic member until the pressure regulating hole is sealed, and can be automatically adjusted according to the negative pressure in the reversing valve body.

[0168] It is understandable that the apertures of the air leakage hole and the pressure regulating hole and the elastic force of the elastic member can be specifically set according to the critical value of the air pressure at which the suction force pulls the sealing portion 352 to meet the need to adjust the air pressure in different situations.

[0169] It is understandable that the elastic member can be a compression spring, a tension spring, a torsion spring, an elastic sheet, or other elastic member, which can provide elastic force to move the sealing portion 352 to open or close the pressure regulating hole. In specific implementation, the cross-sectional area of ​​the sealing member is larger than the cross-sectional area of ​​the pressure regulating hole, and the sealing member covers the edge projection area of ​​the pressure regulating hole along the circumferential direction, and the sealing member can meet the requirements of sealing the pressure regulating hole when it is in contact with the pressure regulating hole.

[0170] It is understandable that the valve core 42 is not limited to a spherical valve core 42 , a sheet-shaped valve core 42 , etc., and can be switched between the first position and the second position so that the first port 411 can be selectively connected to the second port 412 or the third port 413 .

[0171] In one possible implementation, Figure 16-18 As shown, in this embodiment, the valve core 42 is a spherical valve core 42 as an example, and the valve core 42 includes a first flow port 421 and a second flow port 422 that are connected to each other. The first flow port 421 and the second flow port 422 are arranged at an angle, and the first flow port 421 is opposite to and connected to the first through port 411. Fig.19 As shown, when the reversing valve mechanism 4 is in the first working state, the valve core 42 is in the first position, the second flow port 422 is opposite to and communicates with the second port 412, so that the first port 411 is communicated with the second port 412 through the valve core 42; Fig. 20 and Fig.21 As shown, when the reversing valve mechanism 4 is in the second working condition, the valve core 42 is in the second position, the second flow port 422 is opposite to and communicates with the third port 413 , so that the first port 411 is communicated with the third port 413 through the valve core 42 .

[0172] It can be understood that the first flow port 421 always remains relative to and connected with the first port 411, and the reversing motor drives the spherical valve core 42 to rotate, and the spherical valve core 42 rotates with the axis of the first flow port 421 as the rotation center, that is, the axis of the first port 411, so that the second flow port 422 is in a relative and connected position with the second port 412 or the third port 413.

[0173] In one possible implementation, Fig.17 As shown, the reversing valve mechanism 4 also includes a valve seat 47, which can be placed separately in the valve body 41 or as a part of the valve body 41, and is used to abut against the valve core 42 in the axial direction of the third port 413 to limit the valve core 42, and the valve seat 47 includes a cavity for gas to pass through. When the reversing valve mechanism 4 is in the second working state, the cavity is aligned with the first flow port 421 and the third port 413.

[0174] It can be understood that the valve seat 47 can be arranged in the valve body 41 and has a hollow cylindrical shape. One end of the valve seat 47 contacts the inner wall of the valve body 41, and the other end of the valve seat 47 abuts against the valve core 42, which is used to limit the valve core 42 and keep the position of the valve core 42 stable.
