Abstract

The utility model relates to a toothbrush which can not only clean teeth but also protect teeth. The utility model is additionally provided with an elastic wall apparatus to the brush bristle portion of current toothbrushes, encircles brush bristles in the wall entirely, and causes the end surface of the brush bristles to be at the same plane with the end surface of the wall. The elastic limit of the whole of the elastic wall controls the length of the brush bristles extending out the wall in free space lengthwise, and meanwhile, the edges of both sides of the wall control the free eversion of the brush bristles crosswise in order to ensure the brush bristles of the toothbrush to clean teeth at safe length and a standard state and achieve the function of protecting teeth in real meaning.

Description

Elasticity leg tooth protecting toothbrush

The utility model relates to a kind of toothbrush of cleaning teeth, especially passes through the effect of elasticity leg, and plays the toothbrush that takes care of one's teeth and be without prejudice.

At present, existing its structure of toothbrush is basically: the other end at brush holder is equipped with three to four row brush hairs.When using this toothbrush, dentist and dentist warn people will note the method for brushing teeth.Require people when brushing teeth, bristle is vertically placed on the tooth, require simultaneously toothbrush is kept identical horizontal direction with tooth, rotate arm then, bristle is moved up and down at dental surface, reach the purpose of cleaning teeth.

But, brush teeth with current toothbrush and the method that adopts the dentist to require, owing to one being not use strength not reach the purpose that cleans the teeth; The 2nd, change long time, be not suitable for the allegro habits and customs of modern.So majority still adopt the method for Dragsaw type to brush teeth, the result makes bristle constantly destroy healthy tooth.

So current toothbrush can destroy tooth, be because bristle under stress, can't be controlled effectively.The exposed parts of tooth is made up of corona, neck and gum.Corona partly has hard enamel to protect; Gum is made of tough and tensile sheath not predispose to damage; Have neck only, it is between corona and the gum, has both lacked uniform enamel protection, and do not have gum again and take good care of, be a deathtrap.The bristle of current toothbrush, under stress, in the vertical, it can destroy the uneven enamel in neck surface, in depth destroys the bone essence of tooth then, deeply just destroys the structure of dental pulp again.The reason that the wedge shape infringement of Here it is so-called tooth is caused; The bristle of current toothbrush under stress, can produce turning up of not planning simultaneously in the horizontal, and bristle can be peeled away gum and tooth gradually like this.The consequence that causes is, gingival atrophy, and root of the tooth exposes, and tooth mobility comes off at last.Conclusion is: current toothbrush is without any the tooth effect of protecting on the meaning, and on the contrary, it can destroy the tooth of health of people, destroys tooth and produces the damaged material of wedge shape about toothbrush, can find answer in any dentist's handbook or dentistry monograph.

The purpose of this utility model is the irrationality that thoroughly changes current toothbrush, and a kind of toothbrush is provided; it can not only cleaning teeth; and the effect by the elasticity leg, make bristle all can not destroy healthy tooth in the vertical and transversely, reach the purpose that really takes care of one's teeth.

The purpose of this utility model is the principles of science with the rational mechanics and the mechanics of materials, by the brush at current toothbrush, increases that an elasticity wall arrangement enclosure realizes.Specifically be,, increase an elasticity leg, the bristle of toothbrush all is enclosed in the leg regularly, and makes the end face of leg and the end face of bristle, be in the same plane at the brush end of toothbrush.

The elasticity leg is controlled bristle can stretch out leg when the free space position length in the vertical with its elastic limit, and is not producing under the safe length that tooth is destroyed, and reaches cleaning teeth and takes care of one's teeth.This resembles the knife rest of shaver, and it can allow blade shave down beard, but it is the same can not to injure skin.

The elasticity wall arrangement enclosure is also utilized the leg of side, controls in the horizontal that bristle is irregular to turn up, and makes bristle can not destroy gum and interdental adhesion, has prevented the atrophy of gum and root of the tooth exposes and tooth mobility is come off; Simultaneously, leg has the effect that dynamic end face has the massage gum.

Owing to adopted such scheme, elasticity leg tooth protecting toothbrush when brushing teeth, is controlled the length that it stretches out leg at free space in the vertical to bristle, controls it in the horizontal and freely turns up, thereby reached the purpose of protecting tooth.In addition, because the control of elasticity leg has been arranged, people can adopt the mode that is fit to oneself to brush teeth, even Dragsaw type is brushed teeth, also can not damage tooth.On the contrary, because the feasible gravity of going up can reach and can clean the teeth and time-saving purpose, be fit to the allegro life style of modern.

Below, in conjunction with the accompanying drawings and embodiments, the utility model is described in further detail.

Fig. 1 is the utility model structure and station diagram

Fig. 2 is the installation diagram of elasticity wall arrangement enclosure and bristle

Fig. 3 is an elasticity leg fundamental diagram

Among the figure: 1, peripheral wall side 2, leg end face 3, osculum 4, brush holder 5, bristle

In Fig. 1, be thicker leg around the elasticity wall arrangement enclosure, there are two thin walls the centre.Several rows of water hole is respectively arranged at the bottom around leg, and the leg bottom closely links to each other with the toothbrush handles head.Its end face falls into miter angle with the angle of side, and end face is not stayed on the wall end top in dead ahead, to adapt to the back side of the tooth of brushing teeth.

In Fig. 2, the elasticity leg is installed in the brush holder end earlier, then with bristle routinely technology implant the toothbrush handles head, and bristle is repaiied together, make its end face and leg end in same plane.

In Fig. 3, be the sectional view of elasticity leg brush.3-1 is that the elasticity leg is under the normal condition, and the end face of bristle and leg end are in same plane.3-2 be the elasticity leg when brushing teeth, under the stress, the elasticity leg shrinks, bristle stretches out free space, its length is exceeded with elastic limit, guarantees safe length.Because bristle is under safe length and the specification condition and brushes teeth, so played the effect that takes care of one's teeth.

Claims (3)

1, a kind of toothbrush, constitute by brush with bristle and brush holder, it is characterized in that: an elasticity wall arrangement enclosure is arranged at brushhead portion, bristle all is enclosed in the inside, and the end of bristle end face and leg is in same plane, its elastic limit can be controlled the safe length of bristle, and leg can prevent that bristle is irregular and turn up.

2, toothbrush according to claim 1 is characterized in that: fall miter angle between the upper surface of elasticity leg peripheral wall and side, just before the leg upper end, when chamfering, all go.

3, toothbrush according to claim 1 is characterized in that: several rows of water hole is respectively arranged at the bottom around the elasticity leg.
