Household sweeping robot sweeping mechanism

Abstract

The invention discloses a household sweeping robot sweeping mechanism which comprises a machine body, the machine body comprises an exhaust fan, a collecting assembly, a sensor, two sweeping assemblies and two universal wheels; each sweeping assembly comprises a positioning block, a first motor and a dust collecting brush, wherein the first motor is fixedly connected with the positioning block, and the dust collecting brush is connected with an output shaft of the first motor; the machine body is fixedly provided with a second motor, an output shaft of the second motor is fixedly connected with a threaded rod, the end, away from the second motor, of the threaded rod is rotationally connected with the machine body, the thread directions of the two ends of the threaded rod are opposite, the two positioning blocks are in threaded connection with the two ends of the threaded rod respectively, and the machine body is provided with limiting grooves matched with the positioning blocks. The second motor drives the threaded rod to enable the two positioning blocks to move oppositely, then the distance between two dust collecting brushes is reduced, then the two dust collecting brushes rotate reversely to conduct sweeping, garbage located in the middle of the two dust collecting brushes is swept into a collecting assembly, and the garbage cleaning effect is good.

Description

technical field [0001] The invention relates to the field of household cleaning and sanitary appliances, in particular to a cleaning mechanism of a household sweeping robot. Background technique [0002] With the gradual improvement of people's living standards, smart household appliances are widely used. Sweeping robots are a relatively common household cleaning and sanitary appliances. Sweeping robots are generally disc-shaped, equipped with sensors to detect obstacles, and use brush The way of sweeping, the garbage on the ground is sucked into its own garbage storage place, and its function is completed. [0003] Related technologies can refer to the Chinese patent with the announcement number CN204600368U, which discloses a household cleaning robot, including a base, two moving mechanisms, a dust suction mechanism, two side brush mechanisms, a rolling brush mechanism and a follower wheel, a moving mechanism, and a dust suction mechanism. , side brush mechanism, rolling ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when the above-mentioned household cleaning robot is in use, the two side brush mechanisms rotate in reverse to sweep the garbage on the ground between the two side brush mechanisms, and the gap between the two side brush mechanisms The distance cannot be adjusted, and part of the garbage located in the middle of the two side brush mechanisms may not be able to be cleaned. This part of garbage cannot enter the roller brush mechanism, and the cleaning effect on garbage is not good.
