Hair scraping plate for floor brush, and floor brush and vacuum cleaner containing same

Abstract

The present disclosure discloses a hair scraping plate for a floor brush, and a floor brush and a vacuum cleaner containing the same. The hair scraping plate includes a plate body and a plurality of hair scraping pieces. The hair scraping pieces are located on one side of plate body close to a rolling brush. An area of the hair scraping pieces close to the rolling brush is provided with a scraping area. The scraping area has a first structural plane and a second structural plane. At least part of an area of the first structural plane is inclined to one side close to the second structural plane. When the rolling brush rotates, components located at the same position of a soft scraping layer first approach the first structural plane, and then rotate to a direction away from the second structural plane after abutting against an abutting edge.
