[0026] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" refer to the upper and lower positions of the water tank in normal use. Figure 1 and Figure 3 In the drawing direction, "inside" and "outside" refer to the inside and outside relative to the contour of the corresponding component itself. The terms "first", "second", etc. used in this disclosure are to distinguish one element from another element and have no order or importance.

[0028] According to a specific embodiment of the present disclosure, a water tank of a cleaning robot is provided, referring to Figures 1 to 4 As shown, the water tank may include a box body 1, an upper cover 2 and a button assembly 3, wherein a water outlet 11 and a first sealing plug 12 movably connected to the water outlet 11 may be provided at the bottom of the box body 1, and the water outlet 11 can be opened or sealed by moving the first sealing plug 12, the upper cover 2 can be buckled on the top of the box body 1, and a vent hole 21 may be provided on the upper cover 2, and the button assembly 3 can control the movement of the first sealing plug 12 so that the first sealing plug 12 opens or seals the water outlet 11.

[0029] Through the above technical solution, in the water tank provided by the present invention, when it is necessary to discharge the sewage in the water tank, the user only needs to operate the button assembly 3 to drive the first sealing plug 12 to open the water outlet 11, so that the sewage is discharged from the water outlet 11 under the action of gravity, thereby improving the convenience of sewage discharge and avoiding the inconvenience of sewage dumping caused by the excessive weight of the water tank.

[0030] In the specific embodiments of the present disclosure, reference is made to Figures 1 to 4As shown, the button assembly 3 may include a button body 31 and a linkage mechanism 32 connected between the button body 31 and the first sealing plug 12. The button body 31 may be movably covered at the vent hole 21 and has a closed position and an open position. The button body 31 may be configured as follows: in the closed position, the button body 31 seals the vent hole 21 and drives the first sealing plug 12 to seal the water outlet 11 through the linkage mechanism 32; in the open position, the button body 31 opens the vent hole 21 and drives the first sealing plug 12 to open the water outlet 11 through the linkage mechanism 32, so that the sewage in the box body 1 can be discharged through the water outlet 11 under the action of its own gravity. That is, the user only needs to move the button body 31 to the open position to open the vent hole 21 and the water outlet 11 at the same time, so that the sewage can be discharged through the water outlet 11; when the user moves the button body 31 to the closed position, the vent hole 21 and the water outlet 11 can be sealed at the same time, so that the box body 1 has good sealing performance and prevents water from seeping out of the box body 1.

[0031] In the specific embodiments of the present disclosure, reference is made to Figures 1 to 4 As shown, the key body 31 can be rotatably connected to the upper cover 2 through the rotating shaft 311 to realize the movement of the key body 31. The key body 31 can include an operating end 301 and a sealing end 302 for sealing the vent hole 21. The operating end 301 can be set on one side of the rotating shaft 311, and the sealing end 302 can be set on the other side of the rotating shaft 311. When the user rotates the key body 31 around the rotating shaft 311 through the operating end 301, the moving directions of the operating end 301 and the sealing end 302 are opposite. The key body 31 can be configured as follows: when the operating end 301 is pressed downward, the sealing end 302 moves upward, and the key body 31 switches from the closed position to the open position; when the operating end 301 is released, the sealing end 302 moves downward, and the key body 31 is reset from the open position to the closed position. That is to say, the button body 31 can be maintained in the closed position, at which time the sealing end 302 is in close contact with the vent hole 21 and sealed; when the operating end 301 is pressed downward, causing the button body 31 to move from the closed position to the open position, the sealing end 302 can be lifted upward, so that the interior of the box body 1 can be connected to the atmosphere through the vent hole 21, thereby facilitating the discharge of sewage; when the user stops pressing down on the operating end 301, the button body 31 can be reset from the open position to the closed position. During this reset process, the operating end 301 is lifted upward and the sealing end 302 moves downward until it is in close contact with the vent hole 21 and sealed.

[0032] In order to improve the sealing reliability of the sealing end 302 to the vent hole 21, refer to Figure 2 and Figure 4As shown, the lower surface of the sealing end 302 can be provided with a second sealing plug 312 protruding downward. The sealing end 302 can drive the second sealing plug 312 to move upward so that the second sealing plug 312 is pulled out of the vent hole 21, thereby opening the vent hole 21. The sealing end 302 can also drive the second sealing plug 312 to move downward so that the second sealing plug 312 is inserted into the vent hole 21, thereby sealing the vent hole 21.

[0033] In order to enable the key body 31 to be reset from the open position to the closed position, refer to Figure 2 and Figure 4 As shown, a return torsion spring 33 can be sleeved on the rotating shaft 311, and the return torsion spring 33 can provide an elastic force for the button body 31 to return from the open position to the closed position. That is to say, when the user presses the operating end 301 downward to move the button body 31 from the closed position to the open position, the elastic force of the return torsion spring 33 needs to be overcome.

[0034] refer to Figure 1 and Figure 2 As shown, in a specific embodiment of the present disclosure, the first sealing plug 12 can be arranged on the outside of the box body 1, the first sealing plug 12 can move downward to open the water outlet 11, and can move upward to seal the water outlet 11, and the linkage mechanism 32 can include a connecting rod 321, the upper end of the connecting rod 321 can be fixedly connected to the lower surface of the operating end 301, and the lower end of the connecting rod 321 can be fixedly connected to the first sealing plug 12, so that the operating end 301 drives the first sealing plug 12 to move up and down through the connecting rod 321. When the operating end 301 is pressed downward, the first sealing plug 12 can be pushed downward by the connecting rod 321, so that the first sealing plug 12 opens the water outlet 11, and when the operating end 301 is lifted upward, the first sealing plug 12 can be pulled upward by the connecting rod 321, so that the first sealing plug 12 seals the water outlet 11.

[0035] In order to improve the reliability of the key body 31 returning from the open position to the closed position, refer to Figure 2 As shown, the linkage mechanism 32 may further include a first return spring 322 sleeved on the connecting rod 321, the upper end of the first return spring 322 may abut against the lower surface of the operating end 301, the lower end of the first return spring 322 may abut against the upper surface of the upper cover 2, and the first return spring 322 may provide an elastic force for the operating end 301 to move upward.

[0036] refer to Figure 3 and Figure 4In another specific embodiment of the present disclosure, a first sealing plug 12 can be arranged in the box body 1, and the first sealing plug 12 can move upward to open the water outlet 11, and can move downward to seal the water outlet 11. The linkage mechanism 32 may include a pull rope 323, one end of the pull rope 323 can be fixedly connected to the sealing end 302, and the other end can be fixedly connected to the first sealing plug 12. When the user presses the operating end 301 downward to move the button body 31 from the closed position to the open position, the sealing end 302 can pull the first sealing plug 12 upward through the pull rope 323, so that the first sealing plug 12 opens the water outlet 11.

[0037] When the button body 31 is reset from the open position to the closed position, the sealing end 302 moves downward, and since the pull rope 323 is deformed, the sealing end 302 cannot drive the first sealing plug 12 to move downward to seal the water outlet through the pull rope 323. In order to enable the first sealing plug 12 to reset downward, the linkage mechanism 32 may further include a second reset spring 324, one end of which may be fixedly connected to the first sealing plug 12, and the other end of which may be fixedly connected to the box body 1. The second reset spring 324 may provide an elastic force for the first sealing plug 12 to move downward. In other words, when the sealing end 302 pulls the first sealing plug 12 upward through the pull rope 323, the elastic force of the second reset spring 324 needs to be overcome.

[0038] In order to ensure that the first sealing plug 12 can be accurately sealed at the water outlet 11 when falling, refer to Figure 3 and Figure 4 As shown, the first sealing plug 12 may include a connecting handle 121 and a sealing head 122. The connecting handle 121 may be constructed as an L-shaped rod. The L-shaped rod may include a first section extending horizontally and a second section extending vertically downward from the end of the first section. A support 13 may be provided at the bottom of the box body 1. The first section may be rotatably connected to the support 13. The pull rope 323 may be fixedly connected to the first section of the connecting handle 121 to pull the connecting handle 121 to rotate upward. The second return spring 324 may extend obliquely, and the upper end of the second return spring 324 may be fixedly connected to the first section of the connecting handle 121. The lower end of the second return spring 324 may be fixedly connected to the support 13 to pull the connecting handle 121 to rotate downward. The sealing head 122 may be arranged at the bottom end of the connecting handle 121, that is, the sealing head 122 may be arranged at the lower end of the second section. In the above manner, the first sealing plug 12 can rotate around the support 13 in a fixed arc trajectory under the drive of the pull rope 323 and the second return spring 324, so that the first sealing plug 12 can be accurately sealed at the water outlet 11 when falling.

[0039] In addition, reference Figure 3As shown, a vertically extending limit groove 14 can be provided on the side wall of the box body 1 close to the support 13, and the pull rope 323 can be inserted into the limit groove 14, which can not only prevent the pull rope 323 from fluttering in the box body 1, but also make the pulling force given to the connecting handle 121 by the pull rope 323 roughly tangent to the above-mentioned arc trajectory, thereby improving the smoothness of the movement from the closed position to the open position.

[0040] According to a second aspect of the present disclosure, a cleaning robot is provided, comprising the water tank in the above technical solution.

[0041] Through the above technical solution, the cleaning robot provided by the present disclosure has the same technical effect as the water tank in the above technical solution. In order to avoid unnecessary repetition, it will not be described here.
