Description

A kind of toothbrush of interchangeable bristle

Affiliated technical field

The utility model belongs to the daily toothbrush of brushing teeth and using of a kind of people.

Background technology

The present toothbrush that generally uses, the inseparable opening structure that its brush, bristle, brush holder all are fixed as one, when the bristle deformation effect when brushing teeth, a then whole toothbrush must abandon, this can become a kind of waste.Therefore there is the people that the brush of toothbrush is become separable structure with handle designs, when the bristle deformation effect is brushed teeth, just brush is changed, its design feature is that the connecting portion of brush and brush holder is made opposite each other draw-in groove, can not throw off when making this connecting portion stressed, often the chucking degree of draw-in groove will be done very tightly, has caused relatively difficulty of changing brush head like this, has caused inconvenience to use.

Summary of the invention

In order to overcome the defective of prior art changing brush head difficulty, the utility model provides a kind of toothbrush of improved interchangeable bristle, and is convenient when changing bristle, and syndeton is firm.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of toothbrush of interchangeable bristle, comprise brush, bristle and brush holder, it is characterized in that brush be divided into down sheet and separable last slice, following sheet and brush holder are fixed structure, bristle is fixed on slice, following sheet have one with brush holder length to the hole of approximate vertical, with last slice contact position one inner fovea part is arranged above the brush holder, there is a protruding nail that cooperates usefulness with the hole of described down sheet last slice bottom surface, with the contact position of brush holder one projection that cooperates usefulness with described brush holder inner fovea part is arranged above last slice.Above-mentioned hole, inner fovea part, protruding nail, projection all can adopt any suitable appearance; Above-mentioned down sheet and brush holder are that fixed structure can be integrative-structure, also can be the fixed structure of non-one; If with the inner fovea part of above-mentioned brush holder become projection, last slice projection becomes inner fovea part, then should be considered as reaching the equivalent technical solutions of same goal of the invention of the utility model and effect.

The beneficial effects of the utility model are, because brush and brush holder are not whole separable, but brush is separated into last slice and following sheet, following sheet and brush holder are structure as a whole, last slice fixing bristle and installing and be connected down above the sheet, be difficult for when such connecting portion is stressed throwing off, simultaneously since last slice have different projected directions protruding nail and projection, be engaged in down on the corresponding position of sheet and brush holder contact position, such cooperation only needs suitable tightness just very firm, and need not cooperate very tightly, also promptly to change bristle just more convenient to replacing with sheet for this.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is the schematic diagram of an embodiment of the utility model.

Fig. 2 is last slice enlarged drawing of separating with following sheet among Fig. 1.

The specific embodiment

With reference to Fig. 1～Fig. 2, this toothbrush, comprise brush 1, bristle 2 and brush holder 3, feature be brush 1 be divided into down sheet 5 and separable last slice 4, following sheet 5 and brush holder 3 become one structure by injection mo(u)lding, bristle 2 is fixed on slices 4, have on the following sheet 5 one with brush holder 3 long through holes 6 to approximate vertical, with last slice 4 contact position an inner fovea part 7 is arranged above the brush holder 3, there is a protruding nail 8 that cooperates usefulness with through hole 6 last slice 4 bottom surfaces, last slice with the contact position of brush holder 3 projection 9 that cooperates usefulness with inner fovea part 7 is arranged above 4.Will be with last slice 4 when being installed in down on the sheet 5, as long as allow projection 9 fit into inner fovea part 7 earlier, make protruding nail 8 fit into through hole 6 just can to finish by pressing sheet 4 then.When replacing with sheet 4, two hands are held brush 1 and brush holder 3 respectively, crooked gently last slice 4 with the contact position of brush holder 3, projection 9 just can withdraw from inner fovea part 7, protruding then nail 8 just can withdraw from from through hole 6, so last slice 4 just can separate with following sheet 5.
