Central sweeping mechanism of sweeping robot

Abstract

The invention relates to a central sweeping mechanism of a sweeping robot. The central sweeping mechanism comprises a driving motor, a gearbox, a central sweeping rotation shaft and a hairbrush, wherein the driving motor drives the gearbox and drives the central sweeping rotation shaft to rotate, the hairbrush is arranged on the central sweeping rotation shaft, the central sweeping rotation shaft of the central sweeping mechanism is in a split structure, the central sweeping rotation shaft in the split structure adopts the clamping or screwing fixing manner, and a rubber shovel is arranged between the split parts of the central sweeping rotation shaft. The central sweeping rotation shaft is in the split structure, so that the rubber shovel and the hairbrush can be conveniently detached and replaced; through the double cleaning effects of the rubber shovel and the hairbrush, the ground can be well and rapidly cleaned to be tidy, therefore, the cleaning efficiency of the central sweeping mechanism is improved; the rubber shovel is sheet-shaped and is thin in the front and thick in the rear, the front end is provided with a cutting-edge-shaped shovel opening, so that deformation is seldom caused after stressing, and sticking substances difficult to clean on the ground can be conveniently shoveled; the rear end is provided with a column-shaped clamp column, and the clamp column clamps the rubber shovel in a clamp groove, therefore, the rubber shovel has small possibility of becoming loose after being stressed in the cleaning process, and the structure is firm.

Description

technical field [0001] The invention relates to the field of sweeping robots, in particular to a middle sweeping mechanism of a sweeping robot. Background technique [0002] The sweeping robot is a kind of household cleaning appliance, which is deeply loved by people because it can automatically complete the floor cleaning work in the room, saving the time and energy of doing housework. The bottom of the sweeping robot is generally equipped with a middle sweeping mechanism. When working, the robot walks repeatedly in the room according to the preset route. The middle sweeping shaft of the middle sweeping mechanism will rotate continuously to drive the brush to clean the floor. Garbage on the ground, and when the brush is used for a long time, it will become very dirty and the cleaning ability will be reduced. The brush needs to be replaced or cleaned, but because the brush is fixedly installed on the middle sweep shaft or integrally formed with the middle sweep shaft , so i...

Problems solved by technology

The bottom of the sweeping robot is generally equipped with a middle sweeping mechanism. When working, the robot walks repeatedly in the room according to the preset route. The middle sweeping shaft of the middle sweeping mechanism will rotate continuously to drive the brush to clean the floor. Garbage on the ground, and when the brush is used for a long time, it will become very dirty and the cleaning ability will be reduced. The brush needs to be replaced or cleaned, but because the brush is fixedly installed on the middle sweep shaft or integrally formed with the middle sweep shaft , so it is very inconvenient to disassemble and replace the brush. In addition, because the brush is a soft material, it is difficult to clean some stubborn dust, and the cleaning efficiency is low
