Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning component, cleaning device, and cleaning equipment. Background Technology

[0002] With the continuous improvement of technology and people's increasing demands for quality of life, various intelligent equipment has been developed and widely applied in all aspects of people's production and life. For example, the emergence of robot vacuum cleaners can basically replace people in completing household cleaning work, thereby freeing people's hands and improving their quality of life.

[0003] To improve the efficiency of cleaning, robotic vacuum cleaners are usually equipped with a floor mopping function. However, after mopping for a period of time, the brush of the robotic vacuum cleaner will accumulate a lot of dirt. To address this, robotic vacuum cleaners are also equipped with a self-cleaning function to clean the brush while mopping the floor.

[0004] The wastewater and dirt generated by the robot vacuum cleaner's roller brush during cleaning accumulate in the dirt collection tank. While the wastewater is pumped into the wastewater tank for treatment using methods such as vacuuming, dirt still accumulates in the dirt collection tank, causing blockages. Therefore, users need to frequently clean the dirt collection tank of the robot vacuum cleaner, affecting the user experience. Utility Model Content

[0005] Therefore, it is necessary to provide a cleaning component, cleaning device, and cleaning equipment to address the issue that users need to frequently clean the dirt collection tank of the robot vacuum cleaner, which affects the user experience.

The drain support is disposed within the sludge collection tank and is located on the side of the drain valve away from the drain outlet. The first elastic element elastically connects the drain support and the drain valve. When the drain valve opens the drain outlet, the first elastic element accumulates an elastic force to cause the drain valve to close the drain outlet.

[0026] In one embodiment, the cleaning base station is provided with a pusher that can move controllably along the first direction;

[0027] When the cleaning device is located at the cleaning base station, the pusher can abut against the drain valve during movement and drive the drain valve to move in the first direction away from the drain outlet.

[0028] The aforementioned cleaning device, by installing a drain outlet within the sludge collection tank and a drain valve for opening and closing the outlet, allows wastewater to be directly discharged from the tank when the outlet is open, effectively improving the tank's drainage capacity. Thus, when the cleaning device enters the base station, it flushes the tank with a large volume of water, achieving a thorough cleaning and reducing the frequency and time users need to clean the tank.

[0056] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0057] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0058] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0059] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0060] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0061] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0062] See Figure 1 and Figure 2One embodiment of this application provides a cleaning device including a cleaning apparatus 100 and a cleaning base station 400. The cleaning apparatus 100 is used to perform cleaning tasks required by the user, such as sweeping or mopping the floor. The cleaning apparatus 100 includes a cleaning body 102 and cleaning components disposed on the cleaning body 102. The cleaning body 102 can carry the cleaning components and move on the ground, and the cleaning components can be used to perform sweeping or mopping actions on the floor.

[0063] The cleaning components include a dirt-collecting component 110, a cleaning component 200, and a drain valve structure. The cleaning component 200 can be a mop, a roller brush, or other parts that can be used to clean the floor. The cleaning body 102 is also configured to clean the cleaning component. The dirt-collecting component 110 includes a dirt-collecting tank 111, and the wastewater generated by cleaning the cleaning component 200 can be collected in the dirt-collecting tank 111. The dirt-collecting tank 111 is connected to the wastewater tank 101 in the cleaning body 102, so that the wastewater in the dirt-collecting tank 111 can be pumped into the wastewater tank 101 of the cleaning body 102.

[0064] Specifically, when the cleaning device 100 performs self-cleaning, the cleaning body 102 can spray cleaning liquid onto the cleaning component 200, so that after cleaning the floor for a period of time, the cleaning component 200 is cleaned by the cleaning liquid, thereby removing the stains on the cleaning component 200 and allowing the cleaning component 200 to continue cleaning the floor. The wastewater generated by cleaning the cleaning component 200 is collected in the dirt collection tank 111, and the wastewater in the dirt collection tank 111 is pumped to the wastewater tank 101 by a water pump or vacuum pump, thereby preventing the wastewater in the dirt collection tank 111 from overflowing.

[0065] To prevent wastewater from leaking from the collection tank 111 into the external environment and polluting the surrounding environment during the cleaning process of the cleaning device 100, the cleaning device 100 also includes a drain valve 300. The drain valve 300 is movably disposed in the collection tank 111 along a first direction X, which intersects with the longitudinal direction of the collection tank 111. During its movement, the drain valve 300 can open and close the drain outlet 112. Thus, when the cleaning device 100 is cleaning the floor, the drain valve 300 can close the drain outlet 112 to ensure that the cleaning is carried out normally.

[0066] Among them, see Figure 12 and Figure 13The cleaning device 100 can enter or exit the cleaning base station 400 to perform operations such as water replenishment, charging, and cleaning via the cleaning base station 400. The cleaning base station 400 has a wastewater chamber 401, and a wastewater collection tank 111 has a drain port 112 that communicates with the outside of the wastewater collection component 110. When the cleaning device 100 is located in the cleaning base station 400 and the drain valve 300 opens the drain port 112, the drain port 112 connects to the wastewater chamber 401, allowing wastewater in the wastewater collection tank 111 to be discharged through the drain port 112, thereby effectively improving the wastewater discharge capacity of the wastewater collection tank 111. Thus, when the cleaning device 100 enters the base station, it controls the wastewater collection component 110 to discharge a large amount of water into the wastewater collection tank 111, thereby flushing the wastewater collection tank 111 and achieving the effect of cleaning it, thus reducing the frequency and time required for users to clean the wastewater collection tank 111.

[0067] Furthermore, a large amount of water can be directly discharged into the sewage chamber 401 through the sewage outlet, that is, discharged into the base station. This not only facilitates centralized treatment within the base station, but also prevents a large amount of water from accumulating in the sewage collection tank 111, which could cause sewage to overflow and pollute the surrounding environment.

[0068] It should be noted that when it is necessary to control the large amount of water discharged from the dirt-collecting component 110 to the dirt-collecting tank 111, a large amount of water can be discharged through the water outlet structure used by the dirt-collecting component 110 to clean the cleaning component 200. Although the discharged water will pass through the cleaning component 200, it will eventually enter the dirt-collecting tank 111, thereby achieving the effect of cleaning the dirt-collecting tank 111. In some other embodiments, the large amount of water discharged from the dirt-collecting tank 111 can also be achieved by setting a separate water outlet structure.

[0069] Among them, see Figure 6 , Figure 7 and Figure 12 The cleaning base station 400 is provided with a pusher 410, which can move controllably along the first direction X. When the cleaning device 100 is located at the cleaning base station 400, the pusher 410 can extend into the drain port 112 during the movement and abut against the bottom of the drain valve 300. Thus, the pusher 410 drives the drain valve 300 to move along the first direction X toward a direction away from the drain port 112, thereby driving the drain valve 300 to open the drain port 112.

[0070] Furthermore, the cleaning device 100 also includes a drain bracket 320 and a first elastic member 330. The drain bracket 320 is disposed on the dirt-collecting member 110 and located within the dirt-collecting tank 111. The drain bracket 320 is located on the side of the drain valve 300 away from the drain port 112. The first elastic member 330 elastically connects the drain bracket 320 and the drain valve 300. When the drain valve 300 opens the drain port 112, the first elastic member 330 accumulates an elastic force to cause the drain valve 300 to close the drain port 112. Thus, when the pushing member 410 moves away from the drain valve 300, the drain valve 300 can close the drain port 112 under the action of the first elastic member 330.

[0071] Specifically, the drain support 320 is positioned above the drain valve 300. The first elastic element 330 is positioned between the top of the drain valve 300 and the drain support 320. During movement, the pusher 410 abuts against the bottom of the drain valve 300, thereby pushing the drain valve 300 upward and towards the drain support 320, with a stroke of 3-10mm. Opening the drain port compresses the first elastic element 330. Subsequently, the pusher 410 moves away from the drain valve 300, causing the drain valve 300 to move downward under the elastic force of the first elastic element 330, returning to the position where the drain port 112 is closed.

[0072] The aforementioned cleaning device 100, by providing a drain outlet 112 within the sludge collection tank 111 and a drain valve 300 for opening and closing the drain outlet 112, allows wastewater in the sludge collection tank 111 to be directly discharged through the drain outlet 112 when the drain valve 300 is open, thereby effectively improving the sludge discharge capacity of the sludge collection tank 111. Thus, when the cleaning device 100 enters the base station, it controls the device to discharge a large amount of water into the sludge collection tank 111, thereby flushing the tank with a large volume of water and achieving the effect of cleaning the sludge collection tank 111, thus reducing the frequency and time required for users to clean the sludge collection tank 111.

[0073] Some embodiments of this application are described in the references. Figure 3 , Figure 4 and Figure 5 The cleaning assembly also includes a movable suction pipe 120 with a suction port 130, which is connected to the wastewater tank 101 of the cleaning body 102. The suction port 130 can be connected to the sludge collection tank 111 so that the sludge collection tank 111 can be drawn into the wastewater tank 101 through the suction port 130.

[0074] In order to discharge as much wastewater as possible from the wastewater collection tank 111, the drain outlet 112 is located at the lowest point of the wastewater collection tank 111. Simultaneously, to further remove wastewater from the wastewater collection tank 111, the suction outlet 130 of the movable suction pipe 120 also needs to be as close as possible to the lowest point of the wastewater collection tank 111. Thus, when the drain valve 300 opens the drain outlet 112, it will interfere with the movable suction pipe 120. To ensure the normal opening of the drain outlet 112, the movable suction pipe 120 is also movable relative to the wastewater collection component 110 in the first direction X. Furthermore, the drain valve 300, during its movement, can drive the movable suction pipe 120 to move together, thereby enabling the drain outlet 112 to open normally. When the drain valve 300 closes the drain port 112, the suction port 130 is located inside the sludge collection tank 111, so that the movable suction pipe 120 can normally draw sewage from the sludge collection tank 111 through the suction port 130.

[0075] In some embodiments of this application, see [reference] Figure 8 and Figure 9 The cleaning assembly also includes a second elastic member 121 and a fixed suction pipe 122. The fixed suction pipe 122 and the movable suction pipe 120 are connected. The second elastic member 121 elastically connects the fixed suction pipe 122 and the movable suction pipe 120. When the movable suction pipe 120 moves in a direction away from the drain outlet 112, the second elastic member 121 accumulates an elastic force to cause the movable suction pipe 120 to move in the direction of the drain outlet 112.

[0076] Thus, when the pusher 410 pushes the drain valve 300 upward along the first direction X, the drain valve 300 not only compresses the first elastic element 330, but also moves the movable suction pipe 120 along the first direction X, thereby compressing the second elastic element 121. When the pusher 410 moves away from the drain valve 300, the drain valve 300 moves downward under the action of the first elastic element 330, and the movable suction pipe 120 moves downward under the action of the second elastic element 121, so that the movable suction pipe 120 can descend as the drain valve 300 rises.

[0077] In some embodiments, when the drain valve 300 closes the drain port 112, both the first elastic element 330 and the second elastic element 121 are in a compressed state, so that both the first elastic element 330 and the second elastic element 121 can apply a clamping force to the drain valve 300 pressing against the drain port 112. The first elastic element 330 and the movable suction pipe 120 are respectively located on both sides of the drain valve 300's centerline. The centerline of the drain valve 300 is perpendicular to both the first direction X and the axis of the sludge collection tank 111. That is, the first elastic element 330 and the second elastic element 121 are respectively positioned close to the two ends of the drain valve 300 along the axis of the sludge collection tank 111. This allows the clamping force applied to the drain valve 300 by the first elastic element 330 and the clamping force applied to the drain valve 300 by the movable suction pipe 120 to be evenly distributed on the drain valve 300, thereby improving the closing effect of the drain valve 300 on the drain port 112.

[0078] In some other embodiments, see Figure 10 and Figure 11 In this embodiment, there are two first elastic elements 330, and the second elastic element 121 is disposed between the two first elastic elements 330. Thus, the two first elastic elements 330 and the second elastic element 121 jointly press the drain valve 300, ensuring that the pressing force on the drain valve 300 is uniform, thereby improving the closing effect of the drain valve 300 on the drain outlet 112.

[0079] Furthermore, a drain seal 150 is provided at the drain outlet 112. The drain seal 150 seals against the dirt-collecting component 110 and the drain valve 300. The pressure applied to the drain valve 300 by the first elastic component 330 and the second elastic component 121 allows the drain valve 300 to press against the drain seal 150, thereby improving the sealing effect of the drain seal 150 between the drain valve 300 and the dirt-collecting component 110 and reducing water leakage when the drain outlet 112 is closed. The drain seal 150 is a sealing ring, which can be integrally formed with the drain valve 300 or directly sleeved onto the drain seal 150.

[0080] In some specific embodiments, one of the fixed suction pipe 122 and the movable suction pipe 120 is fitted over the other, thereby allowing the movable suction pipe 120 to move relative to the fixed suction pipe 122. The cleaning assembly also includes a movable seal 123, which is sealed between the fitted ends of the movable suction pipe 120 and the fixed suction pipe 122. The movable seal 123 seals the gap between the fixed suction pipe 122 and the movable suction pipe 120, preventing sewage leakage from the gap between them.

[0081] In one specific embodiment, the diameter of the movable suction pipe 120 at the end near the fixed suction pipe 122 is larger than that of the fixed suction pipe 122, so that the fixed suction pipe 122 can be inserted into the movable suction pipe 120. The movable sealing element 123 is a sealing ring, which is sleeved on the fixed suction pipe 122 and is used to seal the gap between the outer wall of the fixed suction pipe 122 and the inner wall of the movable suction pipe.

[0082] Furthermore, the sludge-collecting component 110 is provided with a mounting post 124, and a mounting hole 125 is provided at one end of the mounting post 124. The movable sludge suction pipe 120 passes through the mounting hole 125. A limiting part 126 is provided on the circumferential side wall of the portion of the movable sludge suction pipe 120 located inside the mounting hole 125. The second elastic member 121 is elastically disposed between the limiting part 126 and the fixed sludge suction pipe 122. When the drain valve 300 closes the drain port 112, the end of the limiting part 126 facing the drain port 130 in the first direction X abuts against the mounting post 124.

[0083] Thus, the mounting hole 125 not only limits the extension and retraction of the second elastic member 121, but also limits the movement of the movable suction pipe 120. Furthermore, the limiting part 126 not only prevents the movable suction pipe 120 from dislodging from the mounting hole 125, but also serves to mount the second elastic member 121, facilitating the second elastic member 121 to drive the movement of the movable suction pipe 120.

[0084] In some embodiments of this application, the movable sewage suction pipe 120 continuously presses against the sewage discharge valve 300 under the action of the second elastic member 121. In order to ensure that the movable sewage suction pipe 120 can normally draw sewage through the sewage suction port 130 when the sewage discharge valve 300 closes the sewage discharge port 112, the movable sewage suction pipe 120 is provided with a plurality of sewage discharge columns 140 at intervals at one end with the sewage suction port 130, and all the sewage discharge columns 140 are arranged axially around the sewage suction port 130.

[0085] Thus, when the drain valve 300 closes the drain port 112, all the drain columns 140 are in contact with the drain valve 300, but the sewage in the sludge collection tank 111 will still enter the sludge extraction port 130 through the gap between the two drain columns 140, thereby ensuring the normal extraction of sewage from the sludge collection tank 111 by the movable sludge extraction pipe 120.

[0086] In other embodiments, when it is not necessary to press the drain valve 300 with the second elastic member 121, for example, when both the drain port 112 and the drain valve 300 are circular and the first elastic member 330 is located at the center, when the drain valve 300 closes the drain port 112, the limiting part 126 abuts against the limiting post 301. At this time, the end of the movable sludge suction pipe 120 with the sludge suction port 130 can also have a certain gap with the drain valve 300 in the first direction X. This gap is within 5mm. The sewage in the sludge collection tank 111 is extracted through the gap between the sludge suction port 130 and the drain valve 300.

[0087] In some embodiments, the drain support 320 is provided with a limiting post 301 extending longitudinally along the first direction X, and the drain valve 300 is provided with a limiting hole 321 extending longitudinally along the first direction X. The limiting post 301 passes through the limiting hole 321. During the movement of the drain valve 300 along the first direction X, the limiting post 301 moves along the limiting hole 321. Thus, the cooperation between the limiting post 301 and the limiting hole 321 enables the drain valve 300 to move stably along the first direction X. It should be noted that in some other embodiments, the limiting post 301 may also be provided on the drain valve 300, and the limiting hole 321 may be provided on the drain support 320.

[0088] Furthermore, depending on the shape of the drain hole, there can be one or more limiting posts 301 and limiting holes 321. When the drain hole is circular, there can be one limiting post 301 and one limiting hole 321, which is located at the center of the circular drain hole. When the drain hole is elliptical, there are multiple limiting posts 301 and multiple limiting holes 321. The multiple limiting posts 301 are arranged at intervals, preferably at intervals along the diameter of the ellipse. Each limiting post 301 passes through one of the limiting holes 321. In this way, the rotational freedom of the drain valve 300 is restricted by multiple limiting posts 301 and limiting holes 321, preventing the drain valve 300 from rotating in the planar direction.

[0089] In one specific embodiment, to prevent sewage from flowing into the limiting hole 321 in the sewage collection tank 111, thus preventing the limiting post 301 from moving within the limiting hole 321, a waterproof boss 302 is provided on the side of the drain valve 300 away from the drain port 112, and the limiting hole 321 is located on the top surface of the waterproof boss 302. In actual use, when the drain valve 300 closes the drain port 112, the top surface of the waterproof boss 302 is higher than the drain port 112, thereby preventing sewage from entering the limiting hole 321.

[0090] Furthermore, a fixing hole 303 is provided on the top surface of the waterproof boss 302, and a first elastic element 330 is disposed in the fixing hole 303. The first elastic element 330 is a spring, which is mounted on the drain valve 300 through the fixing hole 303. By placing the spring on the waterproof boss 302, sewage can be prevented from entering the fixing hole 303, thereby preventing sewage from corroding the spring and causing the spring's elasticity to fail. When there are multiple limiting posts 301 and limiting holes 321, one of the limiting posts 301 can also be located in the fixing hole 303 to reduce the problem of sewage entering the fixing hole 303.

[0091] In some embodiments, the drain valve 300 bracket can be installed on two opposite inner walls of the sludge collection tank 111 by means of clips or screws, or the drain valve 300 bracket can be integrally formed with the inner wall of the sludge collection tank 111. In order to avoid interference between the drain valve 300 bracket and the movable sludge suction pipe 120, the drain valve bracket 320 is provided with a clearance hole 322 that extends through along the first direction X, and the movable sludge suction pipe 120 passes through the clearance hole 322 so that the movable sludge suction pipe 120 can extend into the lowest point of the sludge collection tank 111 to extract sewage.

[0092] In some embodiments of this application, a plurality of filter ribs 340 are provided on the side of the drain valve 300 away from the sludge collection tank 111, and all the filter ribs 340 are arranged circumferentially around the sludge suction port 130. In this way, when the drain valve 300 closes the drain port 112, the sewage in the sludge collection tank 111 will gather towards the drain valve 300, and before entering the suction port, the sewage will pass through the filter ribs 340, and the filter ribs 340 will filter the impurities in the sewage, reducing the impurities entering the suction port and preventing the movable sludge suction pipe 120 or the fixed sludge suction pipe 122 from becoming blocked.

[0093] In some specific embodiments, all filter ribs 340 are arranged in two rows along the longitudinal direction of the sludge collection tank 111. Each row of filter ribs 340 includes multiple filter ribs 340 arranged at intervals along the second direction Y. The sludge suction port 130 is located between the two rows of filter ribs 340. The longitudinal direction, the first direction X, and the second direction Y of the sludge collection tank 111 intersect each other. Furthermore, the middle part of the sludge collection tank 111 is set as the lowest point, and the drain port 112 and the drain valve 300 are set at the lowest point in the middle of the sludge collection tank 111. The sewage at both ends of the sludge collection tank 111 will flow along the bottom of the sludge collection tank 111 to the drain valve 300 and be filtered by the two rows of filter ribs 340 respectively.

[0094] In some embodiments of this application, see [reference] Figure 13 , Figure 14 and Figure 15The clean base station 400 includes a base structure 420, a drive component 421, and a transmission component 423. Both the drive component 421 and the transmission component 423 are mounted on the base structure 420. A pusher 410 is movably mounted on the base structure 420 along a first direction X. The drive component 421 drives the pusher 410 to move via the transmission component 423. The drive component 421 can be a motor, and the transmission component 423 includes, but is not limited to, worm gears, racks and pinions 430, etc.

[0095] In some embodiments, the transmission member 423 is a gear, which is connected to the drive member 421. The push member 410 is provided with a rack 430 that extends longitudinally in the first direction X, and the rack 430 meshes with the gear. When the drive member 421 drives the gear to rotate, the gear drives the rack 430 to move, thereby causing the push member 410 to move in the first direction X, and thus pushing the drain valve 300 to move.

[0096] In some specific embodiments, the pusher 410 has an extended position and a retracted position during its movement. When the cleaning device 100 is located at the base station and the pusher 410 is in the extended position, the drain valve 300 opens the drain port 112. When the pusher 410 is in the retracted position, the drain valve 300 closes the drain port 112, and the pusher 410 is positioned away from the movement path of the cleaning device 100 leaving or entering the base station.

[0097] Furthermore, the base station also includes a positioning detection component disposed on the base structure 420. The positioning detection component is used to detect the position of the pusher 410. When the pusher 410 is in the extended position, the positioning detection component outputs a first signal. When the pusher 410 is in the retracted position, the positioning detection component outputs a second signal. The drive unit 421 stops driving the pusher 410 to move according to the first signal or the second signal, thereby causing the pusher 410 to stop at the first position or the second position.

[0098] Specifically, the drive component 421 is a motor. When the cleaning device 100 enters the base station, the motor receives a signal that the cleaning device 100 has reached its position and begins to operate. The drive gear rotates forward, driving the pusher 410 upward through the rack 430, thereby driving the drain valve 300 to open the drain port 112. Furthermore, when the pusher 410 moves to the extended position, the position detection component detects that the pusher 410 is in the extended position and sends a first signal. The drive component 421 stops driving the pusher 410 according to the first signal, so that the pusher 410 stops in the extended position, thereby maintaining the state of the drain valve with the drain port open.

[0099] When the cleaning device 100 needs to leave the base station, the motor receives a corresponding signal and drives the drive gear to reverse, thereby driving the pusher 410 downward through the rack 430 to move away from the drain valve 300. This allows the drain valve 300 to close the drain hole under the action of the first elastic member 330 and the second elastic member 121. Furthermore, when the pusher 410 moves to the retracted position, the position detection component detects that the pusher 410 is in the retracted position and sends a second signal. The drive member 421 stops driving the pusher 410 according to the second signal, causing the pusher 410 to stop in the retracted position, thus preventing the pusher 410 from affecting the movement of the cleaning device 100 away from the base station.

[0100] In some specific embodiments, the positioning detection component includes a first photoelectric switch 425 and a second photoelectric switch 426, which are arranged at intervals along a first direction X. When the pusher 410 is in the extended position, the pusher 410 is positioned away from the second photoelectric switch 426 and partially within the first photoelectric switch 425, so that the first photoelectric switch 425 is triggered, thereby sending a signal that the pusher 410 has moved into position to the processing device of the cleaning base station 400. The processing device then sends a stop signal to the drive 421, thereby stopping the drive 421 from continuing to move, so that the pusher 410 remains in the extended position, the drain hole can remain open until the draining is completed, and the cleaning device 100 needs to leave the base station.

[0101] When the pusher 410 is in the retracted position, it is positioned away from the first photoelectric switch 425 and partially within the second photoelectric switch 426. This triggers the second photoelectric switch 426, sending a signal to the base station's processing device that the pusher 410 has reached its designated position. The processing device then sends a stop signal to the drive 421, stopping its operation and keeping the pusher 410 in the retracted position, thus preventing it from interfering with the movement of the cleaning device 100.

[0102] In some embodiments, one of the base structure 420 and the pusher 410 is provided with a limiting groove 428 extending longitudinally in the first direction X, and the other is provided with a sliding limiting rib 427. The sliding limiting rib 427 is provided in the limiting groove 428 so that the pusher 410 can move stably along the first direction X through the cooperation of the sliding limiting rib 427 and the limiting groove 428, ensuring that the pusher 410 can accurately push the cover to move.

[0103] Specifically, in some embodiments, see [link to relevant documentation]. Figure 16The cleaning base station 400 also includes a motor bracket 429, which is mounted on the base structure 420. The driving component 421, the transmission component 423, and the pushing component 410 are all mounted on the motor bracket 429, so that the driving component 421, the transmission component 423, the pushing component 410 and the motor bracket 429 form a driving module 440. The driving module 440 can be detached separately to facilitate maintenance and replacement.

[0104] A drive hole 441 is provided on the base structure 420. Multiple mounting ribs 442 are provided on the inner wall of the drive hole 441. The drive module 440 is disposed between the mounting ribs 442 and fixed within the drive hole 441 by screws. Furthermore, the base structure 420 also has a cable outlet hole 443. The wire connected to the drive component 421 is connected to the control device of the cleaning base station 400 through the cable outlet hole 443.

[0105] The aforementioned cleaning device 100 can be a robotic vacuum cleaner or a floor scrubber, etc. It features a drain outlet 112 within the dirt collection tank 111, and a drain valve 300 for opening and closing the drain outlet 112. When the drain outlet 112 is opened, the drain valve 300 allows wastewater in the dirt collection tank 111 to be directly discharged through the drain outlet 112, effectively improving the drainage capacity of the dirt collection tank 111. Thus, when the cleaning device 100 enters the base station, it flushes the dirt collection tank 111 with a large amount of water, achieving the effect of cleaning the dirt collection tank 111 and reducing the frequency and time required for users to clean it.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
