[0002] A sweeping robot, also known as a lazy sweeper, is a smart home appliance that can automatically vacuum the floor. It is called a robot because it can detect factors such as room size, furniture placement, floor cleanliness, and rely on built-in programs to develop reasonable cleaning routes and has a certain degree of intelligence.
[0003] At present, when using the sweeping robots on the market, a side brush is installed at the bottom of the sweeping robot to clean the garbage on the ground, so that the dust suction port can collect the garbage. The side brushes on the existing sweeping robots are installed by matching screws during installation. When replacing, the screws need to be loosened and removed by matching tools before the side brush can be replaced. As a result, tools are required to complete the process of replacing the side brush, and the speed of replacing the brush is slow. Therefore, we propose a sweeping robot that is easy to replace the brush. Utility Model Content
