Abstract

A kind of dual-driven electric toothbrush head is brushing apparatus, and which overcome the shortcoming of existing single brush brush, its structural relation is, brush and support, brush seat are integrated, and brush is fixed wtih bristle; Bearing is had in brush seat; Support has perpendicular nibs; In the bearing that lower shaft interts in brush seat and in the bearing of two pieces of stringer boards; Simultaneously; Bent axle interts between two pieces of stringer boards in bearing, and is fixed on there, and the crank of bent axle is positioned in the middle of perpendicular nibs; One end and the motor transmission shaft of bent axle are integrated; The square framework ， that framework is made up of two pieces of transverse slats and two pieces of stringer boards there is the brush hole of settling brush in the middle of Transverse plate; Two crank handle angles of two-way bent axle are respectively 180 degree; Crank diameter is less than the trans D of perpendicular nibs.

Description

A kind of dual-driven electric toothbrush head

Technical field: this utility model relates to brushing apparatus, especially a kind of dual-driven electric toothbrush head.

Background technology: at present, correct use electric toothbrush has the effect of removing dental plaque, caries prevention and periodontitis really, but these effects and ordinary toothbrush are as good as.Electric toothbrush just changes the teeth brushing way of people, can not replace the effect of cleaning teeth as a kind of burnisher completely.Only a lot of people when manual brushes because mode is different, dynamics of brushing teeth is grasped by experience, easily unnecessary damage is caused to tooth and gingiva, and the application target of electric toothbrush alleviates this unnecessary damage, for different crowd occupation mode and feature, fixing brushing mode, proper use of electric toothbrush is the direction that the more humane design of electric toothbrush is produced.If but existing electric toothbrush occupation mode is improper, can damage on the contrary to tooth.Usually be all freely lead to brush teeth up and down with common toothbrush, i.e. perpendicular brush.And electric toothbrush vibration frequency is relative with dynamics fixing, is similar to horizontal brush at dental surface when some product rotates, certain wearing and tearing may be caused to tooth; The sound that the similar dental drill of acoustic toothbrush is the same, can make some people produce fear, particularly child.Early morning, noise brought discomfort can to the people had a rest in use.The key of these problems is teeth brushing way methods of electric tooth brushing.Electric toothbrush vibration frequency is high, and control dynamics is difficult to grasp, and adds that the number of times of brushing teeth abrasive material and every day is easy to cause tooth wear.

Summary of the invention: the purpose of this utility model is to provide that structure is simple, the good a kind of dual-driven electric toothbrush head of toothbrushing effect, which overcome the shortcoming of existing single brush brush, the purpose of this utility model realizes like this, it is by framework, 2 brushes, bristle, support, bent axles, lower shaft, bearing are formed by connecting, brush and support, brush seat are integrated, and brush is fixed wtih bristle; Bearing is had in brush seat; Support has perpendicular nibs.

In the bearing that lower shaft interts in brush seat and in the bearing of two pieces of stringer boards; Simultaneously; Bent axle interts between two pieces of stringer boards in bearing, and is fixed on there, and the crank of bent axle is positioned in the middle of perpendicular nibs; One end and the motor transmission shaft of bent axle are integrated.

The square framework ， that framework is made up of two pieces of transverse slats and two pieces of stringer boards there is the brush hole of settling brush in the middle of Transverse plate.

Two crank handle angles of two-way bent axle are respectively 180 degree; Crank diameter is less than the trans D of perpendicular nibs.

Brush also can be three, and bent axle has three cranks correspond, the angle between three cranks is respectively 120 degree.

Application process of the present utility model is: when we start electric toothbrush switch.Micromachine in handle will drive crankshaft rotating by power transmission shaft.Crank drive brush head bracket in perpendicular nibs of bent axle, makes two brushes do reciprocal reciprocating motion simultaneously.As the crankshaft rotates, crank does 360 degree of rotations thus promotes independent brush and moves reciprocatingly.Namely when people use, the brush in its contact tooth face, brush above is down brushed, and brush below is up brushed; Thus reach the balance and steadily of kinetic energy, serve protection gingiva and cleaning teeth object, avoid and do the improper injury to gingiva when brushing teeth because grasping.

Meaning of the present utility model is: two brush before and after, being changed into by single brush, overcomes the operation of single brush and controls difficult shortcoming; Two, reduce brush yaw speed, alleviate the wearing and tearing to tooth, reduce noise; Three, adopt type of drive respectively, two brush yaw mode is operated on the contrary and simultaneously, the equilibrant counteracting counterforce of generation, thus operate steadily, vibrate less; Four, simple to operate, quick, easily clean.

Accompanying drawing illustrates: Fig. 1 is a kind of structural representation of dual-driven electric toothbrush head, in figure 1, framework 2, brush 3, bristle 4, support 5, bent axle 6, and lower shaft 7, bearing 8, brush seat 9, perpendicular nibs 10, crank

Fig. 2 is the structural representation of support, in figure 2, brush 3, bristle 9, perpendicular nibs.

Fig. 3 is the structural representation of bent axle, in figure 5, bent axle 10, crank

Detailed description of the invention: embodiment 1, this utility model are by framework 1, brush 2, bristle 3, support 4, bent axle 5, and lower shaft 6, bearing 7, brush seat 8 are formed by connecting, brush 2 and support 4, brush seat 8 are integrated, and brush 2 is fixed wtih bristle 3; Bearing is had in brush seat 8; Support 4 has perpendicular nibs 9.

In the bearing that embodiment 2, lower shaft 6 intert in brush seat 8 and in the bearing 7 of two pieces of stringer boards; Simultaneously; Bent axle 5 interts between two pieces of stringer boards in bearing, and is fixed on there, and the crank 10 of bent axle 5 is positioned in the middle of perpendicular nibs 9; One end and the motor transmission shaft of bent axle 5 are integrated.

The square framework ， that embodiment 3, framework 1 are made up of two pieces of transverse slats and two pieces of stringer boards there is the brush hole of settling brush in the middle of Transverse plate.

The angle of two cranks 10 of embodiment 4, two-way bent axle 5 is 180 degree; The diameter of crank 10 is less than the trans D of perpendicular nibs 9.

Embodiment 5, brush 2 also can be three, and bent axle 5 has three cranks correspond, the angle between three cranks is respectively 120 degree.
