The utility model provides a robot 100 sweeps floor.

Referring to fig. 1 to 4, in an embodiment of the present invention, the sweeping robot 100 includes:

a housing 10;

a water tank 20, wherein the water tank 20 is arranged on the shell 10;

a drain pipe 30, the drain pipe 30 communicating with the water tank 20; and

a fluid detection assembly 40, the fluid detection assembly 40 being in communication with the drain pipe 30 and operable to detect water within the drain pipe 30.

The shape of the housing 10 can be designed as a circle. The housing 10 forms the main body of the sweeping robot 100 and may provide mounting and support for other components. In general, a mounting cavity is formed in the housing 10, and a driving component, an electric control component, and the like of the sweeping robot 100 can be mounted in the mounting cavity. In this embodiment, the universal wheels, the cleaning structure and the floor mopping structure of the cleaning robot 100 can be disposed at the bottom of the housing 10, so that the cleaning robot 100 can mop and clean the floor during the traveling process.

The water tank 20 is mainly used for storing water, and in practical applications, when the sweeping robot 100 works, water in the water tank 20 can be discharged to the mop cloth through the water discharge pipe 30 to mop the mop cloth. The fluid detection assembly 40 may be directly installed at the bottom of the housing 10, and the fluid detection assembly 40 is in communication with the drain pipe 30 such that the drain water of the drain pipe 30 can flow through the fluid detection assembly 40, thereby determining whether there is water in the water tank 20 by detecting the drainage of the drain pipe 30.

It is understood that the fluid detecting component 40 can also be a mechanical floating type liquid level meter, so that after being communicated with the drainage pipe 30, a user can directly judge the drainage condition in the pipeline of the drainage pipe 30 by observing the height of the liquid level in the fluid detecting component 40, and then add water to the water tank 20 in time.
