Description

Technical Field

[0001] The utility model relates to the technical field of commercial floor sweeper brush heads, and particularly relates to a brush hair protection device for a commercial floor sweeper. Background Art

[0002] Floor sweeping robots are usually divided into two types: household and commercial. Among them, the household floor sweeping machine body is mainly disc-shaped, generally operated by a rechargeable battery, and generally can be set to clean at a scheduled time and recharge itself. There are sensors installed in the front to detect obstacles. When it encounters a wall or other obstacles, it will turn by itself. Because of its simple operation function and convenience, it has been gradually popularized and has become a common household appliance for office workers or modern families. Commercial electric floor sweepers generally use environmentally friendly new energy storage batteries as power. A blower and a motor are installed on the chassis of a small vehicle, and side brushes and rotary brushes are installed below for combined sweeping and suction. The electric floor sweeper adopts the method of combined sweeping and suction, which is cleaner than traditional manual cleaning. When the sweeping device of the floor sweeper is cleaning, its brush hairs are relatively long and there is no brush hair protection device, so its brush hairs are easy to entangle with hairs and silk threads. When a lot of hairs and other sundries accumulate on the sweeping device, the cleaning ability of this sweeping device will decline, and the brush hairs are also easy to knot and damage. If the hairs and other sundries are not cleaned in time, the entire sweeping device needs to be replaced, resulting in a short service life of the sweeping device. Summary of the Invention
