Toothbrush is a articles for daily use indispensable during people live, and along with the raising of people's living standard, people wish that more and more life is convenient, and the appearance of electric toothbrush has made things convenient for people's life, and it is convenient easy-to-use, allows the people grasp the skill of brushing teeth easily.

But, electric toothbrush in the market generally all is to adopt one or more groups brush, and the bristle on the brush is perpendicular to people's tooth, and the turning cylinder of the brush also tooth with the people is vertical, be the rotational plane and the tooth plane parallel of bristle, this structure makes bristle be difficult to remove dirt between teeth crevice.The electric toothbrush of this structure must keep just reaching reasonable toothbrushing effect with the tooth plane parallel, and bristle is also stabbed gingiva easily.

The electric toothbrush of prior art is confined by traditional manual toothbrush on exterior design on the brush, makes it exist brush big, and single face has bristle, and the characteristics of this brush make the width of cloth of brush up and down of toothbrush brush finish very little, and dental surface is outwash thoroughly.Just because of this defective, though the oral cavity doctor advises that people take the method for brushing teeth up and down, a lot of people are because the toothbrush brush width of cloth is little, movement range is little, and brush is very inconvenient up and down, and therefore many people abandon brushing up and down, and adopt the more horizontal brush method of tooth infringement, promptly about brush.So not only can cause teeth space to clean, more can make odontoseisis.Therefore no matter electric toothbrush or manual toothbrush in the prior art are brushed with which kind of mode and all can be caused dental surface or teeth space can't clean thoroughly.Simultaneously, because the design of the single face of prior art toothbrush brush, can't translation-angle, so the tooth inboard can't large tracts of land scrub, this also is the do not brush teeth reasons of tooth inner surface of a lot of people, can cause surveying in the tooth absurd creature deposition, tooth blackening like this.Electric toothbrush of the prior art is because brush is big, and the wide and thick toothbrush that makes in top can't be deep into inboard molar and wisdom teeth, so that can't brush molar and wisdom teeth, long-term brush is not attended the meeting and caused molar and wisdom teeth pathological changes.Electric toothbrush of the prior art need to brush up and down the residue of removing in the teeth space, but effect is undesirable.

There is the problem of injury gingiva easily in toothbrush of the prior art.If the phenomenon of gingival hemorrhage can appear in people's overexertion when brushing teeth, one of reason is because the bristle meeting when applying external force of the brush of single face design is crooked, the direction of growth contrary of the direction of bristle and tooth during bristles bend, bristle very easily thrusts gingiva along root of the tooth.

Prior art toothbrush silica gel strip all be mostly design in the middle of bristle, scrubbing is can occur and can't contact with tooth comprehensively, the tooth that can't rub significantly can't contact the problem in each place of dental surface etc.This just makes it can't give full play to the effect of oneself, and the effect of tooth whitening also just reduces significantly.
