Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a novel window-cleaning robot. Background Art

[0002] With the development of the economy, more and more people live in high-rise buildings. For the sake of cleaning efficiency and safety, window cleaning machines that can be adsorbed on windows and move have been developed. A negative pressure fan is provided inside the window cleaning machine, and air holes are provided at the bottom of the window cleaning machine. After the bottom of the window cleaning machine is attached to the window, the negative pressure fan and the air holes cooperate to suck air to form negative pressure for adsorption. A cleaning device and a walking device are provided at the bottom of the window cleaning machine. The walking device drives the window cleaning machine to move outside the window. The cleaning device is a floating plate installed on the bottom shell of the window cleaning machine. The floating plate mainly performs simple cleaning of the window glass through the walking action of the window cleaning machine. There are problems of low cleaning efficiency and poor effect.

[0003] Therefore, in the prior art, a roller brush is added to the window cleaning machine, and the cleaning efficiency is improved by driving the roller brush to roll with a motor. The roller brush is usually arranged at the bottom of the machine body, and correspondingly, the floating plate usually has a plurality of avoidance holes for avoiding the walking device (such as tracks), the roller brush and the negative pressure fan respectively. When the negative pressure fan is working, the larger the area of ​​the negative pressure cavity formed, the greater the adsorption force. The area of ​​the negative pressure cavity depends on the size of the avoidance holes. The existing window cleaning robot mainly forms negative pressure through the negative pressure fan and a plurality of air holes. The negative pressure cavity formed is only slightly larger than the area occupied by the plurality of air holes. Therefore, the area of ​​the negative pressure cavity is small, the adsorption force is limited, and the adsorption firmness is insufficient. This is also one of the problems of unstable adsorption and falling off of the existing window cleaning machine. Utility Model Content
