Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 6, the self-overflow tank of the present invention includes a tank 100, a water outlet (not shown) is provided at a tank bottom 101, the tank 100 is further provided with an air hole having one end communicating with a water storage space 110 of the tank 100 and the other end communicating with an outside of the tank 100, the air hole extends from the tank bottom 101 to a top of the water storage space 110 to form an air flow passage 120, an opening 1201 of the air flow passage 120 in the tank 10 has a gap with the top of the water storage space 110, and the tank 100 is further provided with:

an actuator movable relative to the case 100 to intermittently block the air flow path 120 during movement;

a cavity is formed in the bottom 101 of the casing, a boss 1014 is provided in the cavity, and the axle 201 of the moving wheel 200 is coupled to the boss 1014.

The moving wheel 200 supports the case 100 at the case bottom 101 for movement relative to a work surface (ground), and drives the moving member to intermittently block the air flow passage 120 during the movement of the moving wheel 200.

As shown in fig. 1, the actuating member includes a plug 300 and a driving member, the plug 300 is movably disposed in the air flow passage 120, one end of the driving member is connected to the plug 300, and the other end of the driving member is connected to the moving wheel 200, and the driving member drives the plug 300 to move by changing the moving posture of the moving wheel 200.

With the above-described structure, when the moving wheel 200 supports the casing 100 to move relative to the work surface, the moving wheel 200 drives the operating member to intermittently block the air flow passage 120, so that the air pressure in the casing 100 changes between the blocking and the open change of the air flow passage 120. When the air channel 120 is blocked by the acting member, the internal air pressure of the water storage space 110 is lower than the external air pressure of the box body 100, and the external air pressure causes that the liquid in the water storage space 110 cannot flow out from the water outlet hole; when the air flow passage 120 is open, the air pressure inside the water storage space 110 is balanced with the air pressure outside, and the liquid flows out of the water outlet hole under the action of gravity.

Example one

Referring to fig. 1, an air flow passage 120 communicating with a water storage space 110 is provided on a tank bottom 101, a cavity is formed in the tank bottom 101 at an end of the air flow passage 120 near the tank bottom 101, a plug 300 and a moving wheel 200 are provided in the cavity, the cavity is further provided with a lower cover 1011, the lower cover 1011 is provided with a screw hole 1012 fixed to the tank 100 by a screw passing through the screw hole 1012, and the lower cover 1011 forms a part of the tank bottom 101, wherein the moving wheel 200 is mounted on the lower cover 1011.

Wherein, the plug 300 is used as an action member for controlling the on-off state of the air flow passage 120; the moving wheel 200 is disposed on the lower cover 1011, and the moving wheel 200 carrying the box 100 moves on the ground.

Specifically, as shown in fig. 3 and 4, the relative movement between the stopper 300 and the moving wheel 200 is achieved by the interaction of two magnets having the same or opposite magnetic poles, a first magnet 3010 is fixed to the stopper 300, a second magnet 2010 is fixed to the moving wheel 200, and the second magnet 2010 is spaced apart from the first magnet 3010 as the moving wheel 200 rotates. The plugs 300 are driven to be intermittently inserted into or pulled out of the air flow passage 120 by the magnetic force between the magnets during the movement of the moving wheel 200, so that the air flow passage 120 is blocked or unblocked.

When the first magnet 3010 and the second magnet 2010 have opposite poles, as shown in fig. 3, when the second magnet 2010 is deflected to a position that is offset from the first magnet 3010, the first magnet 3010 is in a state of blocking the air flow channel 120, and the air pressure in the water storage space 110 is lower than the external air pressure, so that the stored liquid cannot pass through the water outlet hole due to gravity.

Referring to fig. 4, when the second magnet 2010 is deflected to a position opposite to the first magnet 3010, the first magnet 3010 is moved toward the second magnet 2010 by the attraction force, so that the air flow channel 120 is unobstructed, the air pressure in the stored water 110 is balanced with the outside, and the liquid can flow out of the water outlet hole due to its own weight.

In addition, in the case that the magnetic poles of the opposite ends of the first magnet 3010 and the second magnet 2010 are the same, when the second magnet 2010 is deflected to be opposite to the first magnet 3010, the first magnet 3010 is repelled by the repulsive force and moves upward toward the air flow channel 120, and blocks the air flow channel 120, so that the air pressure in the water storage space 110 is lower than the external air pressure, and the stored liquid cannot pass through the water outlet hole due to gravity.

By means of the structure of the above embodiment, the two second magnets 2010, which have the same and opposite magnetic poles, are alternately arranged on the first magnet 3010 on the moving wheel 200, and this design can make the first magnet 3010 receive the repulsive force and attractive force in a short time in the process of rotating the moving wheel 200, and even achieve the effect of a piston pump when the rotating speed of the moving wheel 200 is fast enough, so as to inject or extract air into or from the water storage space 110.

By the above-mentioned external force, as shown in fig. 2, a spring 1020 is disposed between the plug 300 and the moving wheel 200, specifically, the plug 300 is provided with a first positioning column 302, the bottom 101 of the box body is provided with a second positioning column 1013, one end of the spring 1020 is sleeved on the first positioning column 1020, and the other end is sleeved on the second positioning column 1013. In the illustrated construction, it is contemplated that the spring 1020 may provide an upward force to the plug 300 to cause the plug 300 to block the air flow passage 120, but that in the event that the force of the magnetic force is greater than the tension of the spring 1020, the spring 1020 may be compressed to cause the plug 300 to descend away from the air flow passage 120.

Example two

As shown in fig. 5 and 6, the driving member for driving the stopper 300 is a link 400, one end of the link 400 is rotatably fixed to the stopper 300 by a hinge, and the other end of the link 400 is also rotatably fixed to a position other than the center point of the moving wheel 200 by a hinge. During the rotation of the moving wheel 200, one end of the link 400 pulls the stopper 300 up and down as the moving wheel 200 rotates.

Referring to fig. 5, when the connection point of the link 400 and the moving wheel 200 is raised to the highest position during the rotation of the moving wheel 200, the link 400 pushes the plug 300 to be raised to be in contact with the air flow passage 120, so that the plug 300 blocks the air flow passage.

Referring to fig. 6, when the connection point of the connection 400 and the moving wheel 200 is raised to the lowest position during the rotation of the moving wheel 200, the connection rod 400 pulls the plug 300 down to separate the plug 300 from the air flow passage 120, thereby maintaining the air flow passage open.

EXAMPLE III

Referring to fig. 7, in a design of combining an action member to a moving wheel 200, a wheel surface of the moving wheel 200 has at least one recess 2011, a convex portion protruding from the recess 2011 contacts with an air flow channel 120, and seals the air flow channel 120 during the contact process, so that air outside a water tank cannot enter a water storage space 110, when the recess 2011 is opposite to the position of the air flow channel 120, the air flow channel 120 is exposed to outside air, and the outside air can enter the water storage space 110, so that air pressure in the water tank is balanced, and water can seep out from a water outlet hole by self weight.

Considering that the protrusions generate friction during the contact with the air flow channel 120, the protrusions are made of flexible material, such as film or fluff, and can be in interference contact with the air flow channel 120 and deform during the contact to fill the air flow channel 120, and the deformation characteristics thereof are utilized to reduce the friction effect with the air flow channel 120.

With the self-overflow tank structure in the above three embodiments, referring to fig. 8, the protrusions 2012 are spaced on the outer ring of the moving wheel 200, so that the moving wheel 200 can shake up and down when moving on the ground, and the water outlet holes can be prevented from being blocked by bubbles through shaking. Of course, the shaking motion generated by the motion of the movable wheel 200 can be transmitted to the water tank, so that the air bubbles entering the water outlet holes can be shaken to generate displacement, and the air bubbles are eliminated from the water outlet holes.

The invention also discloses a cleaning robot, which comprises a machine body, wherein a self-overflow tank is detachably arranged on the machine body through a buckling structure, a moving wheel on the self-overflow tank moves along with the machine body on a working surface, the matching state of a plug and an air flow channel is controlled in the moving process to change the air pressure state in a water storage space, cleaning cloth is detachably arranged on the bottom of the self-overflow tank through a magic tape or in a mode of coating the edge of the bottom of the self-overflow tank, and liquid flowing out of the self-overflow tank is soaked on the cleaning cloth.
