Description

Cleaning robot Technical field

The invention relates to a cleaning robot and belongs to the technical field of small household appliance manufacturing.

Background technique

Cleaning robots on the market today usually have suction ports, dust boxes, fans and water tanks. When the dust box, the water tank and the fan are integrated, the user may take out other parts that do not need to be adjusted when they want to clean the dust or add water separately, and the water is easily mixed with the dust, which seriously affects the user experience. When the parts are separated, the water tank is used as a separate accessory. When the mopping function is required, the user then installs the water tank to the lower part of the body. The above structure makes the water tank more easily lost or damaged as a separate component from the whole machine. At the same time, it will indirectly increase the external size of the whole machine in the horizontal or vertical direction, and each time the water tank is filled with water, the body needs to be turned over before the water tank can be taken out. When the water tank is integrated with the whole machine, the water tank is mostly placed side by side with the fan at the side of the whole body, resulting in a small capacity of the water tank.
