[0085] In the following detailed disclosure, the embodiments are fully described with reference to the accompanying drawings, so that those skilled in the art can more clearly and definitely understand and realize the technical scheme of the present application. The following description of the embodiments is not limited thereto, and the present application will be further described in detail below in combination with the embodiments and the accompanying drawings.

[0086] In the present application, the terms "first", "second", "third" are only used for the purpose of description, and cannot be understood as indicating or implying relative importance; the term "multiple" refers to two or more, unless otherwise explicitly limited. The terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, "connecting" can be fixed connection, or detachable connection, or integral connection; "connected" can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0087] The automatic cleaning device returns to the cleaning base after completing the mopping operation, the cleaning element can be a mop disc, and the cleaning base is provided with a raised dirt scraping strip for interfering with the cleaning element during the cleaning process of the cleaning element, so as to remove the dirt on the cleaning element and gather the dirt in the sewage tank. If the residual dirt in the tank is not cleaned or cleaned incompletely for a long time, odor and bacterial growth problems will occur, which will cause secondary pollution of the cleaning element. Generally, the sewage tank needs to be cleaned regularly by being manually cleaned after being detached from the base mechanism. Frequent cleaning is time-consuming and labor-intensive, which affects the user experience. In the process of cleaning the cleaning element, some cleaning bases 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 rotating, the dirt is easily gathered in the edge area of the sewage tank under the action of centrifugal force. By the traditional method of connecting the sewage tank with a water suction pipe to suck out the dirt, a large amount of solid impurities is easily left in the tank, and the tank still needs to be cleaned frequently, which cannot solve the problem of residual solid impurities in the tank.

[0088] The dirt can include liquid impurities and solid impurities, i.e., includes sewage, hair, solid residues, etc.

[0089] The first aspect of the utility model, as Figures 3-13 As shown in the figure, a cleaning disc assembly 1 is provided, which is applied to a cleaning base. The cleaning disc assembly 1 comprises a cleaning disc main body, a dirt scraping piece 12 and a cover plate 14. The cleaning disc main body is provided with a cleaning groove 11 and a collection groove 13 opened on the bottom wall of the cleaning groove 11. The cover plate 14 is arranged on a part of the opening of the collection groove 13 to form an opening connected with the cleaning groove 11. The dirt scraping piece 12 is movably arranged on the cleaning disc main body. At least a part of the opening of the collection groove 13 is located on the moving track of the dirt scraping piece 12. The dirt scraping piece 12 is used to drive the dirt in the cleaning groove 11 to move to the collection groove 13 through the opening.

[0090] The cleaning disc assembly 1 provided by the embodiment of the present disclosure can drive the dirt in the cleaning groove 11 to gather in the collection groove 13 through the movement of the dirt scraping piece 12, so that the solid impurities and non-solid impurities can be gathered in the collection groove 13 and transported to the sewage storage container 31. The residual dirt in the cleaning disc is greatly reduced, the odor caused by the residual dirt in the cleaning disc is reduced, the frequency of manual cleaning of the cleaning disc is reduced, the user's satisfaction is improved, and the dust collection bin 9 and the sewage storage container 31 can be selectively provided with negative pressure through the reversing valve mechanism 4. A gas pump does not need to be provided for the sewage storage container 31, the power module is reduced, the structure of the cleaning base is simplified, and the cost is reduced.

[0091] It can be understood that the scraping member 12 moves in close contact with the cleaning groove 11, and in the moving process, the dirt in the cleaning groove 11 is moved to the opening position of the collecting groove 13, and the dirt falls into the collecting groove 13 through the opening, which can greatly reduce the dirt exposed in the cleaning groove 11 and reduce the generation of odor and bacterial breeding.

[0092] By gathering the dirt in the open cleaning groove 11 in the small space collecting groove 13 through the scraping member 12, the dirt can be easily extracted, and the solid impurities and liquid impurities are mixed together in the collecting groove 13, so that the solid impurities can be extracted together with the liquid impurities.

[0093] The cleaning disc assembly 1 provided by the embodiment of the present disclosure reduces the opening size of the collecting groove 13 by arranging the cover plate 14, so that the ventilation area of the collecting groove 13 to the outside is reduced, thereby enhancing the effect of negative pressure extraction. The cover plate 14 is arranged on the collecting groove 13 and shields part of the slot opening. After the opening size is reduced, it is more difficult for external air to enter the collecting groove 13, so that the pressure in the collecting groove 13 is further reduced, which helps the liquid to be sucked out more smoothly. Under the condition that the negative pressure is certain, the opening size reduction leads to an increase in the flow rate of the liquid passing through the collecting groove 13, thereby improving the suction flow and helping to quickly empty the dirt in the collecting groove 13. The residual amount in the collecting groove 13 is reduced, which can reduce the generation of odor and bacterial breeding.

[0094] It can be understood 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 needs.

[0095] In one implementation manner, as shown in Figures 3-5 The cleaning groove 11 is provided with at least one scraping member 12, as shown in Figures 10-12 The in-groove space profile of the cleaning groove 11 is matched with the moving track of the scraping member 12.

[0096] In the embodiment, the scraping member 12 is taken as an example. When the scraping member 12 is rotationally connected with the cleaning disc main body, the in-groove space of the cleaning groove 11 can be approximately circular.

[0097] In the embodiment, the scraping member 12 is taken as two examples. When the scraping member 12 is rotationally connected with the cleaning disc main body, the in-groove space of the cleaning groove 11 can be approximately ∞-shaped.

[0098] It can be understood that the number of the scraping members 12 can be one, two, three and other integers, the inner space profile of the cleaning groove 11 is adapted to the number, position and moving track of the scraping members 12, and the inner space profile of the cleaning groove 11 is also adapted to the number, position and size of the cleaning elements, so that the cleaning groove 11 can carry the dirt falling from the cleaning elements, and the scraping members 12 can keep adhering to the groove wall during movement to drive the dirt adhering to the groove wall to move with the scraping members 12 until the dirt falls into the collecting groove 13 through the opening.

[0099] As shown in FIG. 1, the cleaning groove 11 is provided with a scraping strip 18 for interfering with the rotating cleaning elements to remove the dirt on the cleaning elements so that the dirt falls and gathers in the cleaning groove 11. Figure 3 As shown in FIG. 1, the cleaning groove 11 is provided with a scraping strip 18 for interfering with the rotating cleaning elements to remove the dirt on the cleaning elements so that the dirt falls and gathers in the cleaning groove 11.

[0100] In an implementation, as shown in FIG. 1, the cleaning groove 11 includes at least two cleaning cavities connected in communication, and each cleaning cavity is provided with a scraping member 12. Figures 10-12 In an implementation, as shown in FIG. 1, the cleaning groove 11 includes at least two cleaning cavities connected in communication, and each cleaning cavity is provided with a scraping member 12.

[0101] It can be understood that the cleaning groove 11 includes cleaning cavities corresponding to the cleaning elements, when the cleaning elements are at least two, the number of the cleaning cavities corresponds to the number of the cleaning elements, and the number of the scraping members 12 corresponds to the number of the cleaning cavities, so that each cleaning element is below a cleaning cavity for collecting the dirt falling from the cleaning element, and each cleaning cavity is provided with a scraping member 12 for cleaning the dirt on the inner wall of the cleaning cavity.

[0102] In an implementation, as shown in FIG. 1, the cleaning groove 11 includes at least two cleaning cavities connected in communication, and each cleaning cavity is provided with a scraping member 12. Figure 4 In an implementation, as shown in FIG. 1, the cleaning groove 11 includes at least two cleaning cavities connected in communication, and each cleaning cavity is provided with a scraping member 12.

[0103] In the embodiment, the number of the cleaning cavities and the scraping members 12 is two, and at least a part of the opening of the collecting groove 13 is located between the two cleaning cavities.

[0104] In an implementation, the collecting groove 13 includes at least two cleaning cavities connected in communication, as shown in FIG. 1. Figure 10 and Figure 11As shown, the cleaning ranges of two adjacent scraper parts 12 have at least some overlap, and the overlapping area is located between the two scraper parts 12. The dirt remaining after one scraper part 12 is cleaned is cleaned by the other scraper parts 12 adjacent to it.

[0105] It is understandable that the multiple scraping parts 12 can rotate in the same direction or in different directions. For example Figure 10 As shown, the multiple scraping parts 12 rotate in the same direction, as... Figure 11 and Figure 12 As shown, the multiple scraping elements 12 rotate in different directions. Specifically, each scraping element 12 can rotate towards the opening to allow dirt to enter from the opening.

[0106] It is understandable that the multiple scraping parts 12 can rotate synchronously or asynchronously. For example... Figure 10 and Figure 12 As shown, the multiple scraping parts 12 rotate synchronously, as... Figure 11 As shown, the multiple scraping parts 12 rotate asynchronously.

[0107] like Figure 11 As shown, this embodiment takes two cleaning chambers and two scraping parts 12, with the cleaning range of two adjacent scraping parts 12 having at least a partial overlap, and the two scraping parts 12 rotating asynchronously in opposite directions. That is, the two scraping parts 12 pass through the overlapping area and the opening of the collection groove 13 in an alternating manner, which makes it easier for one scraping part 12 to clean the dirt thrown out by the other scraping part 12. This can greatly reduce the dirt missed by the scraping parts 12 and achieve a good cleaning effect.

[0108] In one possible implementation, the collection tank 13 includes at least two interconnected cleaning chambers, such as... Figure 12 As shown, there is no overlap between the cleaning ranges of two adjacent scraper parts 12.

[0109] like Figure 12 As shown, this embodiment takes two cleaning chambers and two scraping parts 12, with no overlapping cleaning range between adjacent scraping parts 12, and both scraping parts 12 rotating synchronously in opposite directions. That is, the two scraping parts 12 are approximately mirror images during rotation. When the free ends of the two scraping parts 12 rotate to face each other, they are located on the same straight line. The two scraping parts 12 respectively drive the dirt to gather in front of the opening and move towards the front of the opening, resulting in a good cleaning effect.

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

[0111] It can be understood that the shape of the scraping member 12 is matched with the groove wall of the cleaning groove 11, so that the scraping member 12 can abut against the bottom and / or the side wall of the cleaning groove 11 during movement to remove dirt on the groove wall and make the dirt move with the scraping member 12.

[0112] In an implementation manner, as shown in Figure 9 The scraping member 12 includes a connecting end and a free end, the connecting end is connected with the cleaning disc body, and the scraping member 12 includes an abutting portion 121, the abutting portion 121 is elastic, and the abutting portion 121 is used for abutting against the groove wall of the cleaning groove 11.

[0113] It can be understood that the abutting portion 121 is located at the free end and / or the bottom end of the scraping member 12, that is, the position of the scraping member 12 for abutting against the groove wall of the cleaning groove 11, that is, the hanging strip is arranged in the shape of the groove wall of the cleaning groove 11, the number of the hanging strip is at least one, and the number of the hanging strip can be two and other integers greater than two, and a plurality of hanging strips can clean the groove wall of the cleaning groove 11 multiple times during rotation of the scraping member 12.

[0114] The abutting portion 121 can be made of rubber, silica gel or other elastic materials, so that the abutting portion 121 can be in full contact with the groove wall during abutting of the scraping member 12 against the groove wall of the cleaning groove 11, the cleaning effect is improved, and the residual sewage on the groove wall can be fully removed, the abutting portion 121 applies a pushing force to the solid impurities when the abutting portion 121 abuts against the solid impurities, and the abutting portion 121 can deform to pass through the solid impurities when the solid impurities are stubborn, so that the normal operation of the scraping member 12 is not affected. The scraping member 12 can be partially made of elastic materials, or all of the scraping member 12 can be made of elastic materials.

[0115] In an implementation manner, as shown in Figure 9 In the direction from the connecting end to the free end, the width of the scraping member 12 decreases, so that the front side wall of the scraping member 12 along the rotation direction forms a flow guide surface 122.

[0116] It can be understood that the flow guide surface 122 is an inclined plane or an inclined arc surface, and the flow guide surface 122 guides the dirt close to the connecting end of the scraping member 12 in the cleaning groove 11 to the free end of the scraping member 12 along the flow guide surface 122, so that the dirt can move to the periphery of the cleaning area of the scraping member 12, and then be swept into the opening by the scraping member 12.

[0117] In an implementation manner, as shown in Figure 7 The collecting groove 13 is arranged on the bottom wall of the cleaning groove 11, the collecting groove 13 includes a collecting cavity with an opening, and the dirt in the cleaning groove 11 enters the collecting cavity through the opening.

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

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

[0120] When the collection tank 13 is a split structure, the cleaning tray assembly 1 also includes a cover plate 14. The cover plate 14 and the collection tank 13 enclose a collection cavity, and the cover plate 14 covers a part of the opening of the collection tank 13. Dirt in the cleaning tank 11 enters the collection cavity through the opening not covered by the cover plate 14.

[0121] The cover plate 14 is detachably connected to the main body of the cleaning tray, and the cover plate 14 is detachably connected to the collection tank 13. This allows the cover plate 14 to be easily removed from the main body of the cleaning tray for cleaning, while exposing the collection tank 13 for easy cleaning. This improves the thoroughness of cleaning the cleaning tray assembly 1 and enhances the cleaning experience. Furthermore, when the opening is blocked, the cover plate 14 can be removed for unblocking and maintenance, reducing the probability of malfunctions.

[0122] Among them, such as Figure 5 As shown, the cover plate 14 and the collection tank 13 can be magnetically connected by a magnetic attractor 17. The collection tank 13 is provided with a first magnetic component, and the cover plate 14 is provided with a matching second magnetic component. Alternatively, the cover plate 14 itself may contain magnetic material. When the corresponding positions of the cover plate 14 and the collection tank 13 are close, they can be magnetically connected together. When disassembling, the cover plate 14 can be removed by overcoming the magnetic force. Compared with the traditional bolt connection, the magnetic connection method is simpler in structure, lower in cost, and easier to operate. It reduces the accumulation of dirt and grime, facilitates the installation and removal of the cover plate 14 for cleaning, and improves the efficiency of installation and removal.

[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 and prevents dirt from accumulating 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, such as Figure 7As shown, the side wall of the collecting groove 13 is provided with a dirt suction port 16, the first end of the dirt suction port 16 is communicated with the collecting cavity, and the second end of the dirt suction port 16 extends out of the collecting cavity. The dirt in the collecting groove 13 is sucked out through the dirt suction port 16, so that the cleaning tank 11 can continue to contain the dirt to realize the continuous cleaning of the cleaning element, which is beneficial to improve the cleaning effect, and at the same time, can avoid the secondary pollution caused by the overflow of the dirt in the cleaning tank 11 which is not discharged in time.

[0125] In an implementation manner, as shown in Figure 5 , the outer peripheral wall of the dirt suction port 16 is provided with a sealing gasket 15 with elasticity, the sealing gasket 15 is sleeved on the dirt suction port 16, the sealing gasket 15 can be a tower shape, the dirt suction pipe 81 is connected with the dirt suction port 16 through the sealing gasket 15, and the sealing gasket 15 is used to seal the dirt suction pipe 81 and the dirt suction port 16 to prevent leakage at the connection to cause secondary pollution.

[0126] In an implementation manner, as shown in Figure 7 and Figure 8 , the collecting cavity includes a dirt collecting area 131 and a dirt suction area 132 which are communicated, the height of the dirt suction port 16 is higher than the height of the dirt collecting area 131, and the dirt suction area 132 extends obliquely to communicate the dirt collecting area 131 and the dirt suction port 16. There is a height difference between the dirt collecting area 131 and the dirt suction port 16, the dirt suction port 16 is higher than the dirt collecting area 131, and 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 the residual dirt from flowing out of the dirt suction port 16 to cause secondary pollution to the base.

[0127] In an implementation manner, as shown in Figure 7 and Figure 8 , in the direction from the dirt collecting area 131 to the dirt suction port 16, the flow area of the dirt suction area 132 decreases. The dirt suction area 132 is a horn shape with a wide front and a narrow back, and the side wall of the dirt suction area 132 is an inclined arc surface or an inclined plane, so as to converge the dirt to the position of the dirt suction port 16 along the flow direction, and facilitate the dirt to be sucked out.

[0128] In an implementation manner, as shown in Figure 5 and Figure 6 , the cleaning disc assembly 1 further 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, so as to determine whether the liquid level height in the cleaning tank 11 is within a reasonable range, so as to prevent the secondary pollution caused by the overflow of the dirt in the cleaning tank 11 due to the too high liquid level in the cleaning tank 11, and is beneficial to improve the safety and cleanliness of use.

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

[0130] In the drawings:Figure 5 and Figure 6 As shown, the liquid level detection mechanism 7 includes a first conductive element 71 and a second conductive element 72. When the liquid level in the cleaning tank 11 reaches the position of the first conductive element 71 and the second conductive element 72, an electrical connection is formed between the first conductive element 71 and the second conductive element 72.

[0131] The first conductive element 71 includes a first conductive rubber and a first conductive sheet in contact with each other, and the second conductive element 72 includes a second conductive rubber and a second conductive sheet in contact with each other. The first and second conductive rubbers are disposed inside the cleaning tank 11, and the first and second conductive sheets are disposed outside the cleaning tank 11. The first and second conductive sheets can be disposed on the base mechanism 2. When the liquid level in the cleaning tank 11 exceeds the reasonable range, the liquid level reaches the position of the first and second conductive rubbers, and the first conductive element 71 and the second conductive element 72 form a closed electrical circuit, thereby detecting that the liquid level exceeds the reasonable range and alarming for abnormal liquid level, so as to facilitate timely cleaning of the cleaning tank 11.

[0132] The second aspect of this utility model is as follows: Figures 1-21 As shown, a cleaning base station 100 is provided, including a cleaning disc assembly 1 of any one of the first aspects.

[0133] In one possible implementation, such as Figure 3 and Figure 4 As shown, the cleaning base station 100 also includes a drive mechanism 6, which is connected to the scraper 12 and is used to drive the scraper 12 to move on the cleaning disc body.

[0134] The scraping component 12 is driven by the drive mechanism 6 to move on the main body of the cleaning tray. This movement can be translation, rotation, etc., so that the scraping component 12 keeps in contact with the wall of the cleaning tank 11 during the movement, so as to scrape off the dirt on the tank wall.

[0135] In one possible implementation, such as Figure 6 As shown, the drive mechanism 6 includes a drive motor 61 and a transmission mechanism 62. The drive motor 61 is connected to the connection end of the scraper 12 through the transmission mechanism 62, and is used to drive the scraper 12 to rotate around the connection end as the axis.

[0136] like Figure 6 As shown, the drive mechanism 6 is mounted on the base mechanism 2. The output end of the drive mechanism 6 passes through the main body of the cleaning tray and is connected to the transmission mechanism 62. The number and position of the output ends of the transmission mechanism 62 correspond to the scraper 12. 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 through one of the following: threaded structure, snap-fit ​​structure, or tenon and mortise structure.

[0137] The scraping member 12 can be detachably connected with the output end of the transmission mechanism 62 through a clamping structure. For example, one of the scraping member 12 and the transmission mechanism 62 is provided with a clasp, and the other is provided with a clamping groove. When the scraping member 12 and the transmission mechanism 62 are connected, the clasp is clamped in the clamping groove. When the scraping member 12 and the transmission mechanism 62 are separated, the clasp is separated from the clamping groove.

[0138] Further, a sealing member, such as a sealing ring, can be arranged between the scraping member 12 and the output end of the transmission mechanism 62 to prevent sewage from leaking through the gap between the scraping member 12 and the transmission mechanism 62 and flowing into the transmission mechanism 62 to damage the equipment.

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

[0140] As shown in Figure 13 , the gear set includes a turbine and a first gear coaxially arranged, a second gear and a third gear coaxially arranged, a fourth gear, a fifth gear, a sixth gear, and a seventh gear. The fifth gear is arranged directly below one cleaning cavity, and the seventh gear is arranged directly below the other cleaning cavity. The output shaft of the driving motor 61 is connected with a worm that is meshed with the turbine. The turbine drives the first gear to rotate synchronously to form a speed reducer. The first gear is meshed with the second gear, and the second gear drives the third gear to rotate synchronously. The third gear is meshed with the fourth gear, and the fourth gear is meshed with the fifth gear. The sixth gear is arranged between the fifth gear and the seventh gear and is meshed with both of them. When the fifth gear and the seventh gear rotate in the same direction, one sixth gear can be arranged between the fifth gear and the seventh gear. When the fifth gear and the seventh gear rotate in opposite directions, two sixth gears can be arranged between the fifth gear and the seventh gear. A gap is formed in the cleaning disc body and located at the center of the cleaning cavity. A connecting member is coaxially arranged on the fifth gear and the seventh gear. The connecting member is inserted into the gap to connect with the scraping member 12 and drive the scraping member 12 to rotate in the cleaning cavity.

[0141] In one implementation manner, as shown in Figure 1 and Figure 2As shown, the cleaning base station 100 further comprises a sewage collecting 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 with the collecting groove 13, and the second end of the conveying pipe is connected with the sewage collecting mechanism 3, so as to convey the dirt in the collecting groove 13 to the sewage collecting mechanism 3; the first end of the reversing valve mechanism 4 is connected with the dust collecting bin 9, the second end of the reversing valve mechanism 4 is connected with the negative pressure system 5, and the third end of the reversing valve mechanism 4 is connected with the sewage collecting mechanism 3; the negative pressure system 5 is selectively connected with the sewage collecting mechanism 3 or the dust collecting bin 9 through the reversing valve mechanism 4.

[0142] It can be understood that the first end and the second end of the conveying pipe assembly 8 are connected in communication, so as to convey the dirt in the collecting groove 13 to the sewage collecting mechanism 3. The negative pressure system 5 can be an integrated fan assembly and other components capable of achieving negative pressure through mechanical handover. The integrated fan assembly can include an air extractor, a filter and the like. The reversing valve mechanism 4 is in communication with the negative pressure system 5 and is selectively in communication with one of the dust collecting bin 9 and the sewage collecting mechanism 3, so as to selectively bring the dust collecting bin 9 or the sewage collecting mechanism 3 into a negative pressure state. By setting an integrated fan assembly and a reversing valve assembly for cooperation, the effect of drawing negative pressure on the dust collecting bin 9 and the sewage collecting mechanism 3 can be achieved, the constitution of the cleaning base station power module is reduced, a set of dust collecting fan assemblies and air pumps are reduced, the weight of the cleaning base station is reduced, and the cost is reduced.

[0143] In an implementation manner, as shown in Figure 2 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 and the second end of the reversing valve mechanism 4 are in communication, so as 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 and the second end of the reversing valve mechanism 4 are in communication, so as to connect the negative pressure system 5 with the sewage collecting mechanism 3.

[0144] When the reversing valve mechanism 4 is in the first working condition, the negative pressure system 5 is in communication with the dust collecting bin 9 to draw out the gas in the dust collecting bin 9, so as to bring the dust collecting bin 9 into a negative pressure state. When the reversing valve mechanism 4 is in the second working condition, the negative pressure system 5 is in communication with the sewage collecting mechanism 3 to draw out the gas in the sewage collecting mechanism 3, so as to bring the sewage collecting mechanism 3 into a negative pressure state.

[0145] In an implementation manner, as shown in Figure 14 and Figure 15 the sewage collecting mechanism 3 includes a sewage storage container 31, a sewage discharge port 34 and an air suction port 32 arranged in the sewage storage container 31.

[0146] It can be understood that the height of the exhaust port 34 and the air inlet 32 is above the liquid level in the sewage storage container 31, so as to prevent dirty from entering the air inlet 32 and causing pollution, and prevent dirty from entering the exhaust port 34 and causing backflow.

[0147] In an implementation, the air inlet 32 is provided with a water vapor filter 33 for stopping water vapor and impurities.

[0148] The air inlet 32 is provided with a water vapor filter 33, which allows gas to pass through and blocks water vapor and impurities, removes a large amount of water and impurities in the gas, prevents water vapor in the dirty from entering the reversing valve mechanism 4 and the negative pressure system 5 through the air inlet 32, protects the normal operation of the equipment, and protects the negative pressure system 5, prolongs the service life of the equipment, improves the production efficiency and stability of the equipment. Specifically, the water vapor filter 33 can be a fibrous material or other physical adsorption material to separate water, and the gas is filtered through the water vapor filter 33. The surface of the fibrous material has hydrophobicity, which can separate water vapor in the gas and filter out particulate matter in the gas.

[0149] In an implementation, as shown in Figure 14 and Figure 15 , the sewage collection mechanism 3 further includes a float valve assembly 35, which can move to close or open the air inlet 32 according to the change of the liquid level in the sewage storage container 31, so as to adjust the air pressure in the sewage storage container 31.

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

[0151] It can be understood that by providing the float valve assembly 35 in the sewage storage container 31, the liquid level in the sewage storage container 31 is detected, and the float 351 floats under the action of the liquid. The float 351 is connected to the sealing part 352, and when the float 351 is in contact with the liquid and moves upward as the liquid level rises, the sealing part 352 moves downward correspondingly as the float 351 moves upward. The pre-set liquid level is below the air inlet 32 and the exhaust port 34. When the liquid level in the sewage storage container 31 exceeds the pre-set liquid level, the sealing part 352 is pressed and closes the air inlet 32. When the air inlet 32 is provided with a water vapor filter 33, the water vapor filter 33 is sealed to seal the air inlet 32. When the liquid level in the sewage storage container 31 does not reach the pre-set liquid level, the sealing part 352 is separated from the air inlet 32 to open the air inlet 32.

[0152] The floating valve assembly 35 is arranged to detect the liquid level in the sewage storage container 31, and when the liquid level reaches a preset level, the air suction port 32 is closed, thereby adjusting the air pressure in the sewage storage container 31, stopping the dirty in the collection tank 13 from being pumped out, preventing the sewage storage container 31 from overflowing due to too much dirty, or the dirty from entering the negative pressure system 5 through the air suction port 32, and facilitating timely cleaning of the sewage storage container 31.

[0153] In an embodiment, the sewage collection mechanism 3 further comprises a filter screen arranged in the sewage storage container 31 to separate liquid impurities and solid impurities in the dirty in the sewage storage container 31, and the filter screen is detachably connected to the sewage storage container 31.

[0154] Since the solid impurities and liquid impurities in the cleaning disc assembly 1 are all collected in the sewage storage container 31, when the user pours out the dirty in the sewage storage container 31, the solid impurities are likely to block the sewer or toilet. Therefore, a detachable filter screen is arranged below the sewage outlet 34 in the sewage storage container 31 to separate the solid impurities and liquid impurities in the sewage storage container 31. The filter screen can be detached from the sewage storage container 31 to facilitate separate cleaning of the solid impurities on the filter screen, which helps to improve the thoroughness of cleaning the sewage storage container 31 to prevent the solid impurities from depositing at the bottom of the sewage storage container 31.

[0155] The filter screen can be located at a preset level or above the preset level of the sewage storage container 31. The size and installation position of the filter screen can meet the requirement of completely bearing the dirty 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 outside the floating valve assembly 35 to facilitate separate detachment and removal of the filter screen.

[0156] Further, the detachable connection between the filter screen and the sewage storage container 31 can be achieved by a clamping structure, a limiting structure, a threaded structure, a mortise and tenon structure, a magnetic attraction structure, etc. The edge region of the filter screen can be provided with an upwardly extending fence, which can be circumferentially closed or provided with an opening to limit the solid impurities on the filter screen and make the dirty concentrate on the filter screen when removed.

[0157] In an embodiment, as shown in Figure 2 The conveying pipeline assembly 8 comprises a dirty suction pipeline 81 and an air suction pipeline 82. The first end of the dirty suction pipeline 81 is connected to the collection tank 13, and the second end of the dirty suction pipeline 81 is connected to the sewage outlet 34. The first end of the air suction pipeline 82 is connected to the reversing valve mechanism 4, and the second end of the air suction pipeline 82 is connected to the air suction port 32.

[0158] The sewage storage container 31 is a relatively closed space. The sewage collection tank 13 is connected to the sewage storage container 31 through the sewage suction pipeline 81, and the sewage collection mechanism 3 is connected to the sewage storage container 31 through the air suction pipeline 82. The negative pressure system 5 draws the gas in the sewage storage container 31 out through the air suction pipeline 82 via the sewage collection mechanism 3, so that the sewage storage container 31 is in a negative pressure state, and then the dirty water in the sewage collection tank 13 is drawn out and transported to the sewage storage container 31 through the sewage suction pipeline 81.

[0159] In an implementation manner, as shown in Figures 16-18 The sewage collection mechanism 4 includes a sewage valve body and a steering motor 43. The sewage valve body includes a valve body 41 and a valve core 42. The valve body 41 includes a first through port 411, a second through port 412, and a third through port 413 which 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 through port 411 is connected to the second through port 412. When the valve core 42 is in the second position, the first through port 411 is connected to the third through port 413. The output end of the steering motor 43 is connected to the valve core 42, so as to adjust 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, the third through port 413 is blocked, so that the first through port 411 is connected to the second through port 412, and then the negative pressure system 5 and the dust collection bin 9 are connected, so as to realize the function of drawing out the gas in the dust collection bin 9. When the valve core 42 is in the first position, the second through port 412 is blocked, so that the first through port 411 is connected to the third through port 413, and then the negative pressure system 5 and the sewage collection mechanism 3 are connected, so as to realize the function of drawing out the gas in the sewage storage container 31.

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

[0162] In an implementation manner, as shown in Figure 18 The sewage collection mechanism 4 further includes a photoelectric switch 44. The photoelectric switch 44 is arranged opposite to the valve core 42. The number of the photoelectric switch 44 is at least two, which is used to obtain the in-position information of the valve core 42 in the first position and the second position.

[0163] One photoelectric switch 44 is arranged at the position corresponding to the valve core 42 in the first position, which is used to obtain the in-position information of the valve core 42 in the first position. Another photoelectric switch 44 is arranged at the position corresponding to the valve core 42 in the second position, which is used to obtain the in-position information of the valve core 42 in the second position. Whether the valve core 42 moves to the position is fed back through the photoelectric switch 44.

[0164] In an embodiment, as shown in Figure 18 The reversing valve mechanism 4 further comprises a gas pressure detection mechanism 46 connected to the reversing valve body through the reversing valve base 45. The gas pressure detection mechanism 46 is in communication with 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 a set range, the gas 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. When the suction pipe is blocked and the negative pressure in the reversing valve exceeds a set range, the gas pressure detection mechanism 46 is automatically opened to adjust the gas pressure of the reversing valve body and the suction pipe to prevent failure caused by excessive negative pressure.

[0166] The gas pressure detection mechanism 46 further comprises a pressure regulating hole, an elastic member and a sealing member. The pressure regulating hole is in communication with the inside and outside of the reversing valve body, respectively. The first end of the elastic member is fixed relative 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 a spring force to press the sealing member against the pressure regulating hole. When the gas pressure in the reversing valve body is less than a set value, the sealing member moves away from the pressure regulating hole against the spring force and opens the pressure regulating hole to connect the reversing valve body and the suction pipe 82 with the outside of the reversing valve body.

[0167] It can be understood that a gas venting hole is arranged on the valve body 41 between the third through port 413 and the valve core 42. The sealing member is in abutment with the pressure regulating hole through the elastic member. The two ends of the elastic member are connected to the sealing member and the inner wall of the gas pressure detection mechanism 46, respectively. The elastic member is used to apply a spring force to the sealing member to abut the sealing member against the pressure regulating hole. When the negative pressure in the reversing valve body is too large, the sealing member is pulled away from the pressure regulating hole by suction force to form a gap between the sealing member and the pressure regulating hole for gas flow. The pressure regulating hole is in communication with the inside of the reversing valve body through the gas venting hole to increase the gas pressure in the reversing valve body and the suction pipe. The gas pressure in the reversing valve body gradually increases, the elastic member is reset, and the sealing member moves towards the pressure regulating hole under the action of the elastic member until the pressure regulating hole is sealed. The negative pressure in the reversing valve body can be automatically adjusted.

[0168] It can be understood that the diameters of the gas venting hole and the pressure regulating hole and the spring force of the elastic member can be set according to the critical value of the gas pressure that pulls the sealing part 352 to meet the needs of adjusting the gas pressure in different situations.

[0169] It can be understood that the elastic member can be a compression spring, a tension spring, a torsion spring, an elastic sheet and other elastic components, which can provide an elastic force to move the sealing part 352 to open or close the pressure regulating hole. In a specific implementation, the cross-sectional area of the sealing part is larger than that of the pressure regulating hole, and the sealing part covers the edge projection area of the pressure regulating hole in the circumferential direction. The sealing part can seal the pressure regulating hole in the abutting state with the pressure regulating hole.

[0170] It can be understood 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 through port 411 can be selectively communicated with the second through port 412 or the third through port 413.

[0171] In an implementation, as shown in Figures 16-18 , the valve core 42 is taken as a spherical valve core 42, the valve core 42 includes a first flow port 421 and a second flow port 422 in communication, the first flow port 421 and the second flow port 422 are arranged at an angle, and the first flow port 421 is opposite and communicated with the first through port 411. As shown in Figure 19 , when the reversing valve mechanism 4 is in the first working condition, the valve core 42 is in the first position, the second flow port 422 is opposite and communicated with the second through port 412, so that the first through port 411 is communicated with the second through port 412 through the valve core 42; as shown in Figure 20 and Figure 21 , 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 and communicated with the third through port 413, so that the first through port 411 is communicated with the third through port 413 through the valve core 42.

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

[0173] In an implementation, as shown in Figure 17 , the reversing valve mechanism 4 further includes a valve seat 47, which can be separately arranged in the valve body 41 or can be part of the valve body 41, and is used to abut the valve core 42 to limit the valve core 42 in the axial direction of the third through port 413. The valve seat 47 includes a cavity for gas to pass through, and when the reversing valve mechanism 4 is in the second working condition, the cavity is aligned with the first flow port 421 and the third through port 413.

[0174] It can be understood that the valve seat 47 can be provided in the valve body 41 and is a hollow cylinder, one end of the valve seat 47 is in contact with the inner wall of the valve body 41, and the other end of the valve seat 47 is in abutment with the valve core 42, for limiting the valve core 42 and keeping the valve core 42 stable.

[0175] When the reversing valve mechanism 4 includes the air pressure detection mechanism 46, a through hole corresponding to the air vent hole is formed in the valve seat 47.

[0176] It can be understood that the valve seat 47 can also be part of the valve body 41, that is, the valve body 41 includes a hollow cylindrical portion, and the valve core 42 is in abutment with the valve body 41, for limiting the valve core 42 and keeping the valve core 42 stable.

[0177] In an implementation manner, a sealing ring with elasticity is arranged between the negative pressure system 5 and the reversing valve mechanism 4, and the sealing ring can be soft rubber, so as to improve the sealing performance between the negative pressure system 5 and the reversing valve mechanism 4.

[0178] In a third aspect of the utility model, an automatic cleaning system is provided, which comprises an automatic cleaning device and any one of the cleaning base stations 100 in the second aspect.

[0179] In the description of the present specification, the description of the terms "one embodiment", "some embodiments", "a specific embodiment" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the utility model. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
