Title:
FORMALDEHYDE-REMOVING SWEEPING ROBOT
Document Type and Number:
WIPO Patent Application WO/2022/188377
Kind Code:
A1
Abstract:
Disclosed in the present invention is a formaldehyde-removing sweeping robot, comprising a robot shell, a formaldehyde purification apparatus and a controller. A walking apparatus is arranged at the bottom of the robot shell, and the sweeping robot moves indoors by means of the walking apparatus to clean the floor. A dust collection fan draws air into the robot shell, large-particle impurities are filtered by means of a primary filter screen, and formaldehyde in the air is then primarily absorbed by means of an activated carbon filter screen. A formaldehyde sensor measures the formaldehyde concentration in the air after the air passes through the activated carbon filter screen, and the controller receives formaldehyde concentration data, sent by the formaldehyde sensor, of the air, and determines whether the formaldehyde concentration data exceeds a factory preset formaldehyde concentration value, so as to automatically turn on and off an ultraviolet lamp, such that the technical problem of shortening the endurance time of the sweeping robot caused by the fact that the formaldehyde removal mode of the formaldehyde-removing sweeping robot is single and the ultraviolet lamp cannot be automatically turned on and off is solved.
