Description

Technical Field

[0001] The utility model relates to the technical field of sweeping robots, in particular to a brush mounting structure of a sweeping robot. Background Art

[0002] A sweeping robot is an automated cleaning device, mainly used for floor cleaning in homes or offices. Its main functions include sweeping, vacuuming, mopping, etc. The working principle of the sweeping robot is to use a built-in motor to drive the brush or roller to clean the floor. At the same time, the vacuum device will suck dust and debris into the dust box inside the machine to complete the cleaning operation.

[0003] The bottom of a sweeping robot is generally equipped with two brushes that rotate horizontally and one that rotates vertically. The two brushes that rotate horizontally are used to sweep the garbage toward the side of the brush that rotates vertically, and the brush that rotates vertically is used to sweep the garbage into the garbage box or the suction port of the dust collection device. However, the bottom brushes of most sweeping robots on the market are generally fixed in a complicated way, such as using a large number of fastening screws, complex clamping fixation, etc. The installation and disassembly process is relatively complicated, which is not convenient for replacement operations and brings inconvenience to users. In view of this, we propose a brush installation structure for a sweeping robot. Utility Model Content
