Referring to FIGS. 1 to 7 , the present application provides a cleaning device, which is used for cleaning a surface to be cleaned (such as a horizontal floor). The cleaning equipment performs wet cleaning on the surface to be cleaned by spraying cleaning liquid onto the surface to be cleaned, and sucks sewage into its sewage tank, thereby realizing the cleaning of the surface to be cleaned.

In a schematic scenario, the cleaning equipment is a floor washing machine, which is used to clean the ground. It is worth noting that the cleaning equipment described in the above example is a floor washing machine, which is only one applicable scenario of the cleaning equipment, and the cleaning equipment can also be other types of cleaning equipment, such as floor mopping machines, window cleaning machines wait.

The following description will mainly be made by taking the cleaning equipment as an example of a floor scrubber, but based on the above description, it can be seen that the protection scope of the embodiments of the present application is not limited thereby.

Referring to FIG. 1 to FIG. 3 , the scrubber includes: a body 700 and a box 100 detachably mounted on the body 700 . The above-mentioned box body 100 is a sewage tank, which is used to store the dirt generated when cleaning the ground. Dirt can be understood as a mixture of solid and liquid media. The body 700 is provided with a suction device 710, the suction device 710 is a negative pressure generator, which is used to form a suction airflow in the box body 100, and then suck the dirt on the ground into the above-mentioned box body 100.

The box body 100 includes a box body (not shown in the figure) and a box cover (not shown in the figure). The box body is hollow inside and has an open end to form a receiving cavity 110 inside the box body. Wherein, the box body is an integral structure with one and only one accommodation cavity 110 . The box cover is sealed at the opening of the accommodation cavity 110 of the box body.

Please refer to FIG. 3 , a liquid inlet mechanism 200 is also provided on the tank body, and a dirt inlet channel is arranged on the liquid inlet mechanism 200 . The liquid inlet mechanism 200 also has a liquid outlet 210 that communicates with the dirt inlet channel, and the liquid outlet 210 communicates with the accommodating cavity 110 of the tank body. In this embodiment, the liquid outlet 210 of the liquid inlet mechanism 200 is suspended in the accommodating chamber 110 .

Specifically, the liquid inlet mechanism 200 is a tubular member, and the liquid inlet mechanism 200 extends along the longitudinal direction of the tank body. The liquid inlet mechanism 200 has a fixed end 211 and a suspended end 212 , the fixed end 211 is fixed on the cavity wall of the accommodation chamber 110 , and the suspended end 212 is suspended in the accommodation chamber 110 .

That is to say, the airflow channel 711 is used to communicate with the accommodating cavity 110 of the box body and the suction device. Thus, a suction airflow can be formed in the accommodation chamber 110 , so that external dirt and airflow can be sucked into the box body 100 together.

In this embodiment, the scrubber has a first working state when the box body is inclined relative to the ground, and a second working state when the box body is roughly parallel to the ground.
