As shown in fig. 1 and 2, the present embodiment provides a cleaning apparatus 1, which includes a base station 10 and a cleaning robot 20, which can be combined with or separated from each other, wherein the base station 10 is configured with a delivery pipe 110 and related facilities for performing a cleaning process related to water treatment on a water tank 30 of the cleaning robot 20, in addition to functions of docking and charging the cleaning robot 20. For example, when the main machine 40 of the cleaning robot 20 finishes the cruise cleaning process and stops at the base station, the delivery pipe 110 of the base station extends into the water tank 30 to perform the processes of extracting and recycling the sewage or the residual waste water with the cleaning agent; alternatively, in some embodiments of the present application, before the host 40 is detached from the base station 10, a water storage procedure such as filling water or replenishing water into the water tank 30 is performed through the delivery pipe 110.

Referring to fig. 1 to 3, a water tank 30 according to a first embodiment of the present disclosure includes a tank body 310, a cavity 320, and a sealing structure 330. The surface of the housing 310 is provided with a docking port 311 for the transportation pipe 110 of the base station 10 to correspondingly extend into the housing 310. The cavity 320 is disposed in the box 310 at a position corresponding to the docking port 311, and a water intake 321 is disposed on the cavity 320 at a side opposite to the docking port 311 for communicating the docking port 311 with the internal space 312 of the box 310, so that the conveying pipe 110 can extend into the water intake 321 in the cavity 320, and then extract sewage, waste water, and the like stored in the internal space 312, or inject clean water or detergent into the internal space 312. In addition, in order to extract the sewage and wastewater remained in the inner space 312 as clean as possible, in some embodiments of the present application, the chamber 320 may further include a communication pipe 322 extending from the water intake 321 to the bottom of the tank 310, so that the delivery pipe 110 may perform a cleaning procedure on the residual water accumulated at the bottom of the tank 310 through the negative pressure in the tank 310 and the communication pipe 322.

The docking port 311 of the box 310 and the water intake 321 of the cavity 320 may be coaxially disposed, for example, the docking port 311 is disposed at the top of the box 310, the water intake 321 is disposed at the bottom of the cavity 320 and overlaps with the docking port 311 in the projection direction, so that the conveying pipe 110 may extend into the box 310 along a single direction, which is convenient for operation. In some embodiments of the present application, it is possible to optimize the space utilization of the tank 310 and/or the cavity 320, and the access opening 321 and the water intake opening 321 may be disposed on the sidewall of the cavity 320 in a non-coaxial manner, in which case the delivery pipe 110 may extend into the water intake opening 321 along the path from the access opening 311 to the water intake opening 321 in the form of a hose. In the embodiment of the present application, the port 311 and the water intake 321 are coaxially disposed as an example, but the present invention is not limited thereto.

Referring to fig. 3 and 4, the sealing structure 330 of the water tank 30 is disposed in the cavity 320. The sealing structure 330 includes a body 340 and a resilient member 350, wherein the body 340 is disposed between the docking port 311 and the intake port 321, and the body 340 may be a single component or may be composed of a plurality of different components. In this embodiment, the body 340 includes a plurality of components, such as a driving member 341, a driven member 342, and a connecting member 343. In the relative position of the space, the driving member 341 and the driven member 342 can be regarded as the top end and the bottom end of the overall structure of the body 340, wherein the driving member 341 is pivoted at one side of the docking port 311, the driven member 342 is pivoted at one side of the water intake port 321, and the pivoted positions of the driving member 341 and the driven member 342 are located at the same side in the cavity 320. The connecting member 343 is diagonally pivoted between the driving member 341 and the driven member 342, that is, one end of the connecting member 343 is rotatably connected to one side of the driving member 341 pivoted to the cavity 320, and the other end is also rotatably connected to the other side of the driven member 342 pivoted to the cavity 320.

By the arrangement of the above components, the driving member 341 can swing towards the water intake 321 to be far away from the docking port 311, the driven member 342 can swing towards the docking port 311 to open the water intake 321, so that the driving member 341 and the driven member 342 swing in opposite directions in a split manner (for example, clockwise and counterclockwise swings) in the cavity 320, and the docking port 311 and the water intake 321 are correspondingly opened to communicate the docking port 311 and the water intake 321, or the docking port 311 and the water intake 321 are closed to keep the cavity 320 in a sealed state. Meanwhile, the driving member 341 can drive the driven member 342 to swing synchronously through the connecting member 343, so as to provide the function of synchronously opening or closing the interface 311 and the water intake 321. The driving element 341 and the driven element 342 may be, but are not limited to, a valve that covers the docking port 311 and covers the water intake 321, so that the driving element 341 and the driven element 342 may normally close the docking port 311 and the water intake 321.

It will be appreciated that in order to accommodate the split configuration of the driving member 341 and the driven member 342, the preferred distance between the docking port 311 and the water intake 321 of the chamber 320 on the housing 310 is equal to or slightly greater than the sum of the diameter of the docking port 311 plus the diameter of the water intake 321, such that the height of the chamber 320 within the housing 310 provides for the driving member 341 and the driven member 342 to swing freely within the chamber 320, and such that the driving member 341 and the driven member 342 do not interfere with each other when the docking port 311 and the water intake 321 are open.

In addition, the driving member 341 can better drive the driven member 342 to swing by optimizing the structure of the driving member 341. For example, in the present embodiment, the driving member 341 includes a door 3411, a pivot 3412, and a pulling 3413. Pivot 3412 is attached to door leaf 3411 at one end and is rotatably attached to chamber 320. Therefore, the pivot 3412 and the wall of the cavity 320 are provided with a rotating shaft and a shaft hole or other types of rotating structures, which are engaged with each other, so that the door 3411 can rotate and swing in the cavity 320 through the pivot 3412, thereby shielding or opening the interface 311 (likewise, the same or similar rotating structures are provided on the wall of the follower 342 and the wall of the cavity 320). The elastic element 340 is disposed at the pivot 3412 of the active element 341, wherein one end of the elastic element 340 is connected to the wall of the cavity 320, and the other end pushes the door 3411 to close or abut against the interface 311. Therefore, the elastic element 340 may be, but not limited to, sleeved on the rotating shaft in the form of a torsion spring or connected between the active element 341 and the cavity 320 in the form of a spring sheet or an extension spring, so that one side of the active element 341 is normally abutted against the interface 311 under the elastic bias of the elastic element 340 to shield or close the interface 311.

The pulling part 3413 of the driving part 341 is connected between the door leaf 3411 and the connecting part 343, wherein one end of the pulling part 3413 is connected to the side of the door leaf 3411 adjacent to the pivoting part 3412, and the other end extends from the surface of the door leaf 3411 and is pivoted to the connecting part 343, so that an angle is formed between the length direction of the door leaf 3411 and the extending direction of the pulling part 3413, and thus the pulling part 3413 is used as a moment for pulling the connecting part 343 to displace when the door leaf 3411 swings. The axial direction of the pivotal connection position of the connecting member 343 between the drawing portion 3413 of the driving member 31 and the driven member 342 is parallel to the axial direction of the rotating shaft or the shaft hole, so that the connecting member 343 can be displaced in the same direction by the drawing of the drawing portion 3413, and the driven member 342 is pulled to be separated from the water intake port 321 in the direction opposite to the swinging direction of the door panel 3411.

The application of the embodiments of the present application is further explained below through some scenarios.

Referring to fig. 1 to 4, when the main body 40 of the cleaning robot 20 is separated from the base station 10 for a cleaning cruise task, a certain negative pressure is generated in the inner space of the water tank 30, and the sealing structure in the water tank 30 needs to be capable of resisting the negative pressure to ensure reliable sealing. Therefore, in some embodiments of the present application, the sealing structure 330 further includes a sealing ring 360 disposed around the aperture of the water intake 321, so that the driven member 342 can be adsorbed and pressed on the sealing ring 360 under the negative pressure, thereby further ensuring the sealing strength and preventing the liquid in the water tank 30 from splashing into the cavity 320 or outside the tank 310 through the water intake 321 and the interface 311.

When the host 310 completes the cleaning task and automatically stops at the base station 10, the base station 10 automatically extends out of the delivery pipe 110 to perform the sewage recycling process. The delivery pipe 110 of the base station 10 extends downward into the docking port 311, and pushes against the driving member 341 covering the docking port 311 along the axial direction of the docking port 311, so that the door leaf 3411 of the driving member 341 overcomes the elastic bias applied by the elastic member 340 under the action of an external force, and turns and swings downward toward the water intake 321. At this time, the traction portion 3413 of the driving member 341 pushes the connecting member 343, so that the connecting member 343 pulls the driven member 342 to move in the opposite direction, and the driven member is flipped and swung upward toward the docking port 311, thereby synchronously opening the water intake port 321, and completing the opening of the passage between the docking port 311 and the water intake port 321. At this time, the delivery pipe 110 may continue to descend to the intake port 321, and the sealing of the delivery pipe 110 and the inner space 312 of the tank 310 is completed after abutting against the packing 360 to perform the sewage recovery process. When the wastewater recovery process is finished, the transport pipe 110 goes upward and is detached from the docking port 311. Since the external force applied to the active element 341 disappears, the elastic restoring force of the elastic element 350 acts on the active element 341 to push the door 3411 of the active element 341 against the mating interface 311, thereby closing the mating interface 311. Meanwhile, the connecting member 343 is pulled by the movable member 341 to drive the movable member 342 to flip and swing downward, so that the movable member 342 returns to the initial state of closing the water intake 321, and the inside of the water tank 30 is maintained in a sealed state.

In another application scenario, the water level state in the water tank 30 may be detected in advance before the main unit 40 of the cleaning robot 20 performs the auto-cruise task. If the water level needs to be raised, the delivery pipe 110 of the base station 10 may also push the driving member 341 shielding the access opening 311 downward and open, so that the door panel 3411 of the driving member 341 turns and swings downward toward the access opening 321, and drives the driven member 342 to turn and swing upward toward the access opening 311, thereby opening the access opening 321, completing the opening of the passage between the access opening 311 and the access opening 321, and allowing the delivery pipe 110 to be connected to the access opening for water injection. And after the water filling process is completed, the delivery pipe 110 moves up to the initial position, so that the driving member 341 and the driven member 342 close the interface 311 and the water intake 321 again. The host machine 40 can now be detached from the base station 10 to perform a clean cruise task.

Through the above description, the cleaning device 1, the cleaning robot 20 thereof, and the water tank 30 provided in the embodiment of the present application, through the inward opening design of the driving part 341, the conveying pipe 110 of the base station 10 can be directly inserted into the water tank 30 after going down, and the butt joint can be realized through one action, which is simple and efficient; meanwhile, through the outward opening design of the driven part 342, the driven part 342 is attracted to the water intake 321 by the negative pressure existing in the water tank 30 at ordinary times, and the sealing reliability is ensured along with the increase of the suction force. Moreover, through the diagonal pin joint of the connecting member 330, the driving member and the driven member can be ensured to realize simple operation of simultaneous switching, no redundant action is generated, the operating efficiency is improved, and the electronic control switch can replace complex structures such as an electronic control switch, and has the advantage of effectively reducing the cost. In addition, when the delivery pipe 110 is butted with the water intake 321, the sewage and the waste water in the water tank 30 cannot enter the cavity 320 under the sealing action of the sealing ring 360, so that each component of the sealing structure 330 is not polluted by the sewage or corrosive liquid, and the reliability of the mechanism and the service life of the component are greatly improved.

It is worth noting again that in the prior art, an outward-opening cover (which is turned over outside the tank) is usually provided on the side of the docking port outside the tank to close the docking port or turn the docking port open. This kind of configuration often causes the carrying (water) pipe of basic station to get the water tank when getting the water, must open the apron through user's manual hand in advance and expose the interface after, the raceway just can dock with the interface to stretch into the water tank and get the water. Therefore, in operation, the water pipe at the lower part cannot be directly opened to the interface, which causes inconvenience in use. However, if the cover plate is disposed in the water tank in an inward opening manner (i.e., turned inside out of the water tank) to close the docking port, the cover plate is sucked downward under the negative pressure inside the water tank, which may cause air leakage, which may affect the operation of the cleaning robot or cause water in the water tank to splash to the external environment through the docking port.

In the embodiment of the present application, the active member 341 is disposed in the water tank 30 in an inward-opening manner (inward-opening manner), and the docking port 311 is closed by the elastic bias of the elastic member 350, so that the active member 341 can provide good airtightness at the docking port 311 and cannot be sucked away by the negative pressure in the water tank 30 from the viewpoint of sealing, safety and reliability, and can also provide water or water injection by directly inserting the delivery pipe 110 of the base station 10 into the water tank 30 from the outside. The intuitive operation mode increases the convenience in use and improves the user experience. In addition, it is considered that water inside the water tank 30 is easily splashed or leaked through the docking port 311. Therefore, the driven part 342 closes the water intake 321 in an outward opening mode (outward opening mode), and has linkage with the driving part 341, so that the interface 311 and the water intake 321 can be synchronously opened or closed, the operation program is saved, and meanwhile, the requirement of sealing performance can be met.

Furthermore, it will be appreciated that in some embodiments of the present application, particularly in embodiments where the water intake is not provided with a sealing ring, a sealing ring or similar sealing assembly may optionally be provided on the nozzle of the delivery pipe abutting the water intake to achieve the sealing effect when the delivery pipe and the water intake are abutting.

Referring to fig. 5, a side view of a water tank according to a second embodiment of the present application is shown. The water tank provided in the second embodiment of the present application is substantially the same in structure as the water tank provided in the first embodiment, and the difference between the two embodiments is that in the water tank 30 of the present embodiment, the elastic member 350 of the sealing structure 330 is connected between the active member 341 and the wall surface of the cavity 320 in the form of a compression spring or a resilient sheet, and a slope 3414 is provided on the side of the active member 341 facing the docking port 311. One end of the elastic member 350 is connected to the active member 341, and the other end is connected to the wall surface of the cavity 320 along the horizontal direction, so that the active member 341 is normally maintained at a position adjacent to the docking port 311, and shields the docking port 311. Meanwhile, the active member 341 can move closer to or away from the interface 311 in the horizontal direction by the elastic force of the elastic member 350, so as to shield or open the interface 311. For example, when an external force acts on the inclined surface 3414 of the active member 341, the active member 341 compresses the elastic member 350 and moves away from the docking port 311 in the horizontal direction, so that the docking port 311 is opened; and when the external force disappears, the driving member 341 is close to the docking port 311 along the horizontal direction under the action of the elastic restoring force, so that the docking port 311 is shielded or sealed by the driving member 341.

As shown in fig. 1, 2 and 5, therefore, in the application scenario of the second embodiment of the present application, when the duct 110 of the base station 10 goes down and applies an external force to the active part 341, the active part 341 is pushed by the inclined surface 3414 of the active part 341 to compress the elastic part 350 in the horizontal direction and move away from the docking port 311, so as to open the docking port 311. In the process, the connecting member 343 moves along with the driving member 341 and pulls the driven member 342 to flip and swing upwards towards the direction of the access opening 311, so as to open the water intake opening 321, complete the opening of the channel between the access opening 311 and the water intake opening 321, and enable the conveying pipe 110 to be connected with the water intake opening 321 for wastewater recovery or water injection.

It is understood that, in other embodiments of the present application, a concave-convex matching structure extending along the horizontal direction may be further selectively disposed on the wall surfaces of the driving member 341 and the cavity 320, and the concave-convex matching structure serves as a sliding track when the driving member 341 reciprocates along the horizontal direction, so as to improve stability when the driving member 341 moves closer to or away from the interface 311. In addition, in some embodiments of the present application, the driving member 341 and the driven member 342 may also be directly connected in a mutually pivoted manner by structural design, so as to omit the configuration of the connecting member 343, thereby simplifying the number of components of the sealing structure 340.

Referring to fig. 6 and 7, in comparison with the first and second embodiments of the present invention, in the water tank 30 provided in the third embodiment of the present invention, the body 340 of the sealing structure 330 is selectively configured as a single component. The body 340 has opposite top 344 and bottom 345 ends, the top 344 being adjacent to the interface 311 and the bottom 345 normally covering the intake 321. Wherein, the side of the body 340 facing the interface 311 is provided with a slope 346 obliquely connected to the bottom 345 from the top 344, and the interface 311 is shielded by the slope 346. The connecting member 350 may be in the form of a compression spring or a resilient plate, and is connected to the wall surface of the cavity 320 and the other side of the body 340 opposite to the inclined surface 346 in the horizontal direction, so that the body 340 can be displaced in the horizontal direction (i.e. the radial direction of the interface 311) by the elastic force of the elastic member 350 to compress or release the elastic member 350.

When the body 340 is compressed by the elastic member 350 under the action of an external force, the top end 344 and the bottom end 345 of the body 340 are respectively far away from the butt joint port 311 and the water intake port 321 along the horizontal direction, so that the water intake port 321 is opened to conduct a channel between the butt joint port 311 and the water intake port 321; and when the external force disappears, the body 340 releases the elastic member 350 and moves to the initial position under the action of the elastic restoring force, so that the bottom 345 of the body 340 closes the water intake 321, and the inner space 312 of the box 310 returns to the sealed state.

In addition, in some embodiments similar to the present embodiment, in the case that the water intake 321 is provided with the sealing ring 360, by performing a proper structural design on the bottom end 345 of the body 340, for example, providing a guiding slope or a step structure at the position where the bottom end 345 is attached to the periphery of the sealing ring 360, when an external force acts on the side of the body 340 provided with the slope 346, the side of the body 340 pressed on the opposite side of the sealing ring 360 can be correspondingly lifted from the sealing ring 360, so as to release the negative pressure adsorption state between the bottom end 345 and the sealing ring 360, and the bottom end 345 of the body 340 can be smoothly separated from the sealing ring 360, so as to open the water intake 321 more quickly.

Referring to fig. 1, 2, 6 and 7, in an application scenario of the third embodiment of the present application, the conveying pipe 110 of the base station 10 descends and applies an external force on the inclined surface 346 of the body 340, pushing the body 340 to compress the elastic member 350 along the horizontal direction, so as to make the top end 344 of the body 340 far away from the docking port 311, and at the same time, to make the bottom end 345 of the body 340 removed from the water intake port 321. At this time, the passage between the port 311 and the water intake 321 is conducted, so that the delivery pipe 110 can extend into the cavity 320 and be connected to the water intake 321 for wastewater recycling or water injection.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
