Cooperating structure of brush head and brush cover

Abstract

The invention discloses a matching structure of a brush head and a brush cover. When a brush head body is covered with the brush cover, a press block is pressed to push a trapezoidal block, push blocks below the trapezoidal block are pushed away towards two sides to drive fixed rods to be pushed, and consequently baffles connected with the brush cover through rotary shafts are pushed away, and an opening in the side wall at the lower end of the brush cover is expanded. Thus, when the brush head body is covered with the brush cover, bristles arranged on the brush head body cannot be bent.

AI Technical Summary

Problems solved by technology

[0002] The brush head of the general skin brush now includes a brush body, and a plurality of bristles are planted on the brush body, because the bristles are very soft, so when the skin brush is not used, the bristles need to be covered with a cover to protect the bristles; but When the above-mentioned cover is intended to cover the bristles, the edge of the opening of the cover often touches and bends the bristles, causing the bristles to be damaged.

[0003] In view of the above problems, the patent application number is "CN98202352.9", and the name is "Structure-improved face brush" which discloses a structure of a brush cover. There is a gap on the side wall of the brush cover, and the brush cover needs to be used to cover the bristles. At this time, it is only necessary to slide the brush body into the brush cover along the gap in the horizontal direction; although the above-mentioned structure avoids defects such as easy bending of the bristles when the brush cover directly covers the bristles, it has changed the current mainstream adoption of directly inserting the brush The way the cap snaps onto the bristles, making it difficult for consumers to accept

In addition, in order to allow the brush head to slide in, the gap set on the side wall must be relatively large, resulting in the easy entry of external dust and other pollutants.

[0004] And if the bristles are directly applied to make the bristles close when the cover is about to be covered, the bristles need to be squeezed directly, which will damage the soft bristles and reduce the life of the bristles.
