Description

A kind of anti-bristle deformation toothbrush

technical field

The utility model relates to a toothbrush, in particular to an anti-deformation toothbrush.

Background technique

The main part of the toothbrush is the bristles arranged vertically on it. During the process of brushing teeth, the ends of the bristles constantly elastically rub against the tooth surface, and can reach into the gap between the gums to remove dirt. However, if you use too much force when brushing your teeth, the bristles on the toothbrush are prone to excessive bending and deformation, resulting in the bristles only sliding on the surface of the teeth during brushing, so that the gums cannot be cleaned thoroughly.

Especially for electric toothbrushes, the toothbrush head is usually detachably fixed on the toothbrush drive handle, and the toothbrush head with too low life will lead to frequent replacement, and the toothbrush head needs to be adapted to the drive handle, and the cost of repurchasing is high.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a toothbrush that prevents the deformation of the bristles.

The technical scheme that the utility model solves its technical problem adopts is:

An anti-bristle deformation toothbrush, comprising a toothbrush handle and a toothbrush head, the toothbrush head includes bristles and a brush seat for implanting the bristles, and the brush seat is provided with a height lower than the The limit boss of the bristle.

The surface of the limiting protrusion is elastic.

The brush base includes a hard support and an elastic covering covering the end of the hard support; the hard support is provided with a through hole, and the elastic covering extends through the through hole to form the Limiting boss.

The end surface of the rigid bracket is provided with a raised fixing post.

Elastic bumps are distributed on the other side of the toothbrush head.

The elastic protrusions are integrally formed by the elastic covering member.

The position-limiting protrusion is concealed in the area where the bristles are located.

The limiting post is a cross-shaped post.

The beneficial effect of the utility model is: by setting the limiting convex column on the toothbrush head with a height lower than the bristles, the limiting convex column can avoid the excessive bending and deformation of the bristles caused by excessive force when brushing teeth, so that the oral cavity is cleaned more thoroughly , At the same time, it is more durable and improves the service life of the toothbrush.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the front view of the utility model;

Fig. 3 is a structural schematic diagram of the toothbrush head of the present invention.

detailed description

With reference to Fig. 1, Fig. 2, a kind of anti-bristle deformation toothbrush comprises toothbrush handle 1 and toothbrush head 2, and toothbrush head 2 comprises bristle 21 and the brush holder 22 for described bristle 21 implantation, and described brush holder 22 is in bristle The setting end surface of the bristles 21 is provided with a limiting protrusion 23 whose height is lower than the bristles 21 . By setting the limit post 23 on the toothbrush head 2 with a height lower than the bristles, excessive bending and deformation of the bristles 21 due to excessive force can be avoided when brushing teeth, so that the oral cavity is cleaned more thoroughly, and at the same time it is more durable, improving the toothbrush service life.

Referring to FIG. 3 , further, in order to avoid uncomfortable contact with the oral cavity due to the excessive rigidity of the position-limiting post 23 , the surface of the position-limiting post 23 can be made elastic by adopting the manufacturing method of built-in bracket encapsulation. That is, the brush holder 22 is composed of a hard bracket 3 and an elastic covering 4 covering the end of the hard bracket 3; wherein the hard bracket 3 is provided with a through hole 31, and the elastic covering 4 extends through the through hole 31 in the The other end forms a limiting post 23, which can improve the appearance and feel of the product, and at the same time, the connection between the two is tighter and the reliability is higher.

Further, a raised fixing post 32 is provided on the surface of the end of the hard bracket 3, so that it fits with the elastic covering part 4, and the elastic covering part 4 is not easy to loosen; The outer surface can be used as a decorative pattern.

The other side of the toothbrush head 2 is distributed with elastic protruding points 24, and the elastic protruding points 24 can be integrally formed by the elastic covering member 4, which can scrub the tongue coating when brushing teeth, and clean the oral cavity more thoroughly.

The limiting protrusion 23 is concealed and arranged in the area where the bristles 21 are located, and the overall appearance is more integrated. The limiting post 23 can be a cross-shaped pillar, which can have at least two or more stress concentration points when subjected to radial force, has higher structural strength, and is not easy to bend, deform or even break. The area where the bristles 21 are located will be obviously hollow, and the distribution will be more uniform.

The structure of the utility model is simple and practical, and can be widely used in various toothbrushes. Especially for electric toothbrushes, the detachable toothbrush head 2 needs to be specially purchased and matched, and the service life is longer after the structural scheme of the utility model is adopted. Long, thus reducing the cost of use, with high market prospects and economic benefits.
