Abstract

The utility model relates to a toothbrush which comprises a base for a brush head portion and a rear brush handle thereof, wherein, the base of a brush head portion is linked with brush bristles. The utility model is characterized in that the front part of the brush bristles is lower than the rear part of the brush bristles, and the arrangement of the brush bristles forms an oblique shape. The utility model is more accorded with the physiological structure of the bilateral mouth cavity, enhancing the toothbrushing efficiency.

Description

The plagiohedral toothbrush

The utility model relates to a kind of toothbrush.

The present thick about 0.4cm of toothbrush head portion pedestal, about the long 1cm of bristle, the bristle plane is horizontal, and the middle part that also has is lower slightly.This toothbrush weak point has: one, be difficult for brushing the buccal surface portion of grinding one's teeth in sleep at the rear.Usually the people has 32 permanent teeths, and wherein four third molars (molar) will just begin to sprout about 20 years old.Cheek and grind one's teeth in sleep between roughly shape is in an angle.When cheek is heaved, it is big that angle becomes, and the gum buccal groove increases, and forms certain space.Yet more backward the closer to the angle end of this angle, change also more little, molar process especially.Therefore both made and heaved cheek, the gum buccal groove of molar process is still quite narrow.Equally high before and after the present toothbrush bristle, do not meet physiological structure herein, the height of brushhead 1.4cm also is not easy to stretch into herein.Bristle is longer in addition, and relatively more soft, the bristle tip that then is in operation more is difficult for being sent to the place ahead of operation, and the position that is difficult for brushing is just long more.Two, since at present the height of toothbrush have to magnify when making us brush teeth the occlusal surface of tooth near the ultimate range between grinding one's teeth in sleep up and down, one loosens and will bite toothbrush slightly.So the  face of grinding one's teeth in sleep of four parts all must be brushed under this state up and down, easily makes the oral cavity produce sense of fatigue.

The purpose of this utility model is exactly at above-mentioned weak point, existing toothbrush is improved, provide a kind of and can meet both sides, oral cavity physiological structure, be convenient to go deep into the rear, cleaning teeth to greatest extent, and do not make the oral cavity produce the plagiohedral toothbrush of sense of fatigue in the process of brushing teeth.

Technical solution of the present utility model:

A kind of plagiohedral toothbrush, it includes brushhead pedestal (1) and rear portion brush holder (2) thereof, is connected with bristle (3) on the brushhead pedestal (1), it is characterized in that the front portion of bristle (3) is lower than the rear portion, they be arranged as inclined plane shape.

The utility model is toothbrush bristle plagiohedral first and arranges, and the brushhead pedestal is a wedge type, make toothbrush meet the physiological structure of both sides, oral cavity like this, be easy to deeply, especially after the head bristle reduces, hard relatively, and short, the hard easier position, the place ahead that is sent to operation, bristle tip, can brush the rear to a greater extent and grind one's teeth in sleep.And since the brushhead base thickness reduce, when brush to grind one's teeth in sleep sting the  face time, more laborsaving.The inclined-plane of bristle and curve inclined-plane are arranged in addition, more meet the teeth arrangement radian, can contact tooth more in large area, improve brushing efficiency.

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

Fig. 2-the 3rd, two kinds of structural representations in addition of the present utility model.

In the utility model, the inclined plane shape that bristle (3) is arranged can be trapezoidal inclined plane, As shown in Figure 1, also can be curve slope. This curve slope can be anterior level, middle part To the rising of rear portion curvilinear style, as shown in Figure 2, also can be anterior slightly high, the middle part is flat to the rear portion Curvilinear style rises, as shown in Figure 3. Brushhead pedestal of the present utility model (1) is wedge Type, its anterior thickness is slightly less than rear portion thickness.

Such as Fig. 1-3, the utility model has reduced the thickness of brush, makes toothbrush from the side See to be plagiohedral, namely reduced thickness and the bristle (3) of toothbrush head pedestal (1) Length, make bristle (3) plane be low early and high after plagiohedral, be equipped with again the wedge type base Seat (1), not only beloid on the width, and also low early and high after on the height, meet mouth The physiological structure of both sides, chamber has improved brushing efficiency.

Embodiment:

The anterior thickness of brushhead pedestal of the present utility model (1) can be 0.3cm, and this place's bristle (3) highly is 0.5-0.7cm, and the rear portion thickness of brushhead pedestal (1) is 0.4cm, and rear portion bristle (3) highly still is 1cm, and pedestal (1) is a wedge type.Brush body brush afterbody thickness is 1.4cm still like this, and the brush front portion has only 0.8-1.0cm, has reduced about 1/3rd than original.Moulding is gone forward narrow, Bao Houkuan, thick is easy to go deep into the both sides, oral cavity, and especially brushhead bristle (3) has shortened 1/3rd to 1/2nd, and the easier operation position, the place ahead that is sent to, bristle tip brushes the rear to a greater extent and grinds one's teeth in sleep.When brush when grinding one's teeth in sleep occlusal surface, ground one's teeth in sleep up and down apart from just much of that about 1cm in the rear, than original low by about 1/3rd.Oral cavity and cheek portion indefatigability.If adopt Fig. 2,3 curved face type, not only possess the advantage of above-mentioned plagiohedral, also can contact tooth more in large area, improve brushing efficiency.

Claims

1, a kind of plagiohedral toothbrush, it includes brushhead pedestal (1) and rear portion brush holder (2) thereof, is connected with bristle (3) on the brushhead pedestal (1), it is characterized in that the front portion of bristle (3) is lower than the rear portion, they be arranged as inclined plane shape.
