Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-7 As shown, a vacuum cleaner and an anti-tangling roller brush include a shaft 1, a roller brush body 2 is provided on the shaft 1, bearing components 4 are provided at both ends of the shaft 1, the bearing components 4 are provided in the bearing seat 3, a plurality of bristles 21 are vertically provided on the roller brush body 2, and a guide component 5 is provided at both ends of the roller brush body 2, at least a part of the guide component 5 intersects with the bristles 21 at the ends of the roller brush body 2. A roller brush body 2 is mounted on a shaft 1, and bearing components 4 are mounted at both ends of the shaft 1. The bearing components 4 are located inside bearing seats 3. Several brush bristles 21 are vertically mounted on the roller brush body 2. The brush bristles 21 are made of nylon. Guiding components 5 are mounted at both ends of the roller brush body 2. At least part of the guiding components 5 intersects with the brush bristles 21 at the ends of the roller brush body 2. By providing guiding components 5, when the roller brush body 2 rotates, the guiding components 5 can guide hair, debris, etc. on the roller brush body 2 inward, thereby preventing hair, debris, etc. from being rolled into the bearing components 4, effectively increasing the service life of the machine and improving the user experience.
