Abstract

The utility model relates to a shrinking toothbrush, solving the problem that when the traditional toothbrush brushes to the temporal inferior frontal joint part, the front end brushing is forced to be bent due to the small space, resulting that the second and the third molars and the tooth seam can not be cleaned well. The toothbrush comprises brushings, a brush body and a brush handle. The toothbrush is characterized in that the brush body consists of a front brush body, a middle brush body and a back brush body, and the brush body and the brush handle are integrated into a whole body. The front brush body from the joint with the middle brush body to the end of the toothbrush is naturally bent to the brushing side. The end of the brush body extends to 1/2 of the height of the middle brushing and the back brushing. The height of the middle brushing and the back brushing is the same as that of the normal brushing. The front brushing is naturally shortened along the arc slope of the front brush body to make sure the brushing working faces are on the same plane, and the natural shrinkage shape of the brushing from the back to the front is formed. When in use, and when the brushing comes to the mouth temporal inferior frontal joint part, the front brushing is naturally bent because of the front brush body satisfying the space demand of the part, and the brushing is still kept in erection state to ensure the second and the third molars and the tooth seam be brushed. The toothbrush is simple and convenient, and the tooth brushing demand can be satisfied without being transformed technically.

Description

The body toothbrush contracts

Technical field

The utility model relates to a kind of toothbrush, exactly discloses a kind of body toothbrush that contracts.

Background technology

The toothbrush of Shi Yonging has a variety of in the market, be embodied in the design of bristle working face, mainly contain anterior and posterior height bristles unanimous on the whole such as horizontal shape, waveform, dogtooth, semilune, abrading-ball shape and sharpening shape, more than the design of various bristles, not only guaranteed cleaning, and can both remove well the swill in the teeth crevice, tartar etc. to the tooth face.Therefore occupy the very big market share, be subjected to consumer's popular welcome.But, the design of above-mentioned all kinds of bristle moulding also exists the some shortcomings part, exactly when brushing teeth, when the bristle of toothbrush brushes second, the 3rd when grinding one's teeth in sleep, part space, volume joint is less under the temporo in oral cavity, the bristle of toothbrush head is forced to bending, and long brush hairs can not be brushed into teeth space, and the effect of brushing teeth reduces greatly.

Summary of the invention

The utility model is primarily aimed in the oral cavity under the temporo that volume joint space position is narrow and small, bristle is forced to crooked so that cleaning teeth well, reduces toothbrushing effect and discloses a kind of body toothbrush that contracts.Mainly comprise: bristle, brush body and brush holder, it is characterized in that: brush body is by front brush body (4), middle brush body (5), back brush body (6) constitutes, and front brush body (4), middle brush body (5) and back brush body (6) respectively account for 1/3 of brush body length overall, be that front brush body (4) is in brush body (5), (6) the orthogonal projection length on the extended line equates respectively with the length of middle brush body (5) and back brush body (6), and it is one-body molded with brush holder (7), front brush body (4) from the place that contacts of brush body (5) begin to the end portion of front brush body (4), side to the bristle of planting curves perk naturally, and the end of front brush body (4) is with respect to middle brush body (5), exceeding of back brush body (6) highly is middle bristle (2), 1/2 of back bristle (3) height; Bristle is made of preceding bristle (1), middle bristle (2), back bristle (3), and respectively account for 1/3 of bristle length overall, in bristle (2), the back bristle (3) identical with normally used bristle height, preceding bristle (1) shortens naturally along the arc of front brush body (4) is domatic, and guarantee that the common bristle working face that constitutes of preceding bristle (1), middle bristle (2) and back bristle (3) remains on same plane, and, form bristle and shorten shape naturally to middle bristle (2) to preceding bristle (1) by back bristle (3) with middle brush body (5) and the common brush body back side keeping parallelism of forming of back brush body (6).When brushing teeth when bristle walks under the temporo of oral cavity position, volume joint (8) (referring to Fig. 2), preceding bristle (1) curving naturally because of front brush body (4), and be unlikely to be forced to bending, the shape of still being kept upright, being suitable for this position narrow space needs, thereby guarantees the cleaning of scrubbing to the 3rd (9), second grind one's teeth in sleep (10) (referring to Fig. 2) and teeth space.This technology is not only simple and convenient, and need not too big change technically, can satisfy the needs of brushing teeth of science.

Description of drawings

Referring to accompanying drawing, Fig. 1 is the structural representation of traditional toothbrush;

Fig. 2 be traditional toothbrush when brushing to temporo volume joint part before the variation schematic diagram of bristle;

Fig. 3 is the utility model structural representation;

Fig. 4 is the utility model bristle distribution schematic diagram;

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further;

Referring to Fig. 3, Fig. 4, be structural representation of the present utility model and bristle distribution schematic diagram, brush body is made of front brush body (4), middle brush body (5) and back brush body (6), and it is one-body molded with brush holder (7), front brush body (4) from the contact portion of brush body (5) begin to end to the end of front brush body (4), one side to the bristle of planting curves perk naturally, before bristle (1) on front brush body (4) domatic, shorten naturally from low to high, and make preceding bristle (1) and middle bristle (2), afterwards the working face of bristle (3) remains on same plane.During use toothpaste is squeezed in the bristle working face, send into the oral cavity after dipping in water, front, reverse side to tooth are scrubbed repeatedly, when brush body stretches under the temporo volume joint part, preceding bristle (1) curves because of the natural energy of front brush body (4), reduced the taking of oral cavity space, made preceding bristle (1) shape of still being kept upright, thereby good cleaning action is played in the slit of grinding one's teeth in sleep and grind one's teeth in sleep.Because the natural torsion of brush body front end uses the sense without any discomfort, can play cleaning action better than traditional toothbrush.And this fabrication techniques is simple, and is easy to use, the more science of brushing teeth.
