The connecting rod 1323 connects the second contact portion 1322 to the movable block 1321. The elastic member 133 elastically connects the first contact portion 1313 and the second contact portion 1322. The elastic member 133 is, for example, a spring, and in some other embodiments, the elastic member 133 may also be other elastic members such as a spring sheet.

By elastically connecting the second contact portion 1322 of the piston 132 to the first contact portion 1313 of the seal bushing 131, the default state of the movable block 1321 is set to the state of closing the passage T1, and the movement of the piston 132 in the axial direction is restricted, so that the piston 132 is prevented from completely separating from the seal bushing 131 and falling off when moving in the axial direction.

In some embodiments, the passage T1 has a second opening K2 disposed opposite to the first opening K1, and in the second state, the external liquid enters the passage T1 from the second opening K2.

A liquid delivery device 820 is located within the housing 600. The liquid delivery device 820 includes an inlet 821 and an outlet 822, the inlet 821 communicating with the reservoir 810. Nozzle 830 communicates with liquid outlet 822. The nozzle moving device 840 includes a mounting portion 841 and a moving portion 842. Mounting portion 841 is connected to case 600, and movable portion 842 is movable relative to mounting portion 841. The movable portion 842 is connected to the nozzle 830, so that the movable portion 842 can move the nozzle 830.

In some embodiments, the liquid delivery device 820 is, for example, a water pump assembly. The mounting portion 841 is, for example, swingably connected to the housing 600 so that the movable portion 842 can be lifted and lowered. In some embodiments, the nozzle moving device 840 may further include a driving member, such as a driving motor, capable of driving the moving portion 842 to move relative to the housing 600. After the alignment sensor 700 is aligned with the cleaning robot 1000, the driving member drives the movable portion 842 to descend, so that the nozzle 830 is communicated with the check valve assembly 130 of the cleaning robot 1000, the liquid conveying device 820 starts to work, and the liquid in the liquid storage tank 810 is input into the dirt collecting chamber 111 through the check valve assembly 130, thereby cleaning the dirt collecting chamber 111.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all of which are under the conception of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings, or direct/indirect application in other related technical fields are all included in the patent protection scope of the present invention.
