Technical Field

[0001] The invention relates to the technical field of noise reduction of window cleaning robots, and in particular to a noise reduction air duct structure of a window cleaning robot. Background Art

[0002] Window cleaning robots are a type of smart home appliance that requires electricity to work. With the continuous improvement of living standards, they are gradually replacing manual cleaning. Window cleaning robots use the vacuum suction cup or fan at the bottom of the body to create a vacuum between the body and the glass, so that they can firmly adhere to the glass. The two wheels rotate to wipe the glass, achieving the purpose of cleaning, solving the problem of outdoor or high-altitude glass cleaning.

[0003] At present, the window-cleaning robot mainly relies on the vacuum pump or fan device at the bottom of itself to firmly adhere to the glass. Regardless of whether it is a vacuum pump or a fan device, wind enters the vacuum pump or the fan device. Both air ducts are not closed. The generated airflow flows out from the inside of the window-cleaning robot. Since many components are arranged inside the device, there are too many components where the wind flows through and too many obstacles on the route. This flow mode of airflow will produce a larger airflow turbulence sound, and the generated turbulent noise will make people feel uncomfortable.

[0004] To this end, the present invention provides a noise reduction air duct structure for a window cleaning robot to solve the above-mentioned problem. Summary of the invention
