Cooperating structure between brush head and brush cover for preventing bristles from bending

Abstract

The invention discloses a brush head and brush cover cooperation structure preventing bristles from bending by pressure. When a brush cover is to cover a brush head body, a press block is pressed to push a trapezoid block, so that pushing blocks under the trapezoid block are pushed to two sides, and pushing of the pushing blocks to two sides drives a moving rod, so that a sliding block connected with the moving rod moves. One end of a fixing rod is connected with the sliding block, and the other end of the fixing rod is connected with a second rotation shaft which is arranged below a first rotation shaft on a baffle plate. The sliding block is pushed in a sliding chute, and the baffle plate is pushed through the fixing rod. Thus, the brush cover can be pushed open by the baffle plate which is connected with the rotation shafts, and side wall openings on the lower ends of the brush cover are expanded. Thus, when the brush cover covers the brush body, the brush cover would not bend the bristles on the brush head body by pressing the bristles.

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.
