Description

A kind of toothbrush

The utility model belongs to a kind of toothbrush.

Present tooth play generally comprises bristle, acute handle and handle three parts, and its acute face is plane or waveform, and the brush holder of fasten bristles is indeformable.But, because being arcuation, people's tooth distributes, brush finish can not coincide with teeth patterning preferably, can not clean the inboard and the outside of tooth most effectively.

Being of the purpose of this utility model provides a kind of toothbrush, satisfies people when the inboard of brushing teeth and the outside, make brush finish can and people's tooth better identical.

For achieving the above object, this toothbrush comprises bristle, brush holder and handle, wherein brush holder comprises the anamorphic attachment for cinemascope of bristle fixed block and change bristle fixed block shape, this device is made up of spring, backguy, push-and-pull chain, backguy one end is fixed on the bristle fixed block, the other end links to each other with the push-and-pull key after changing direction by brush holder, and the push-and-pull key is fixed on the handle.When the outside of brushing teeth, one draw the push-and-pull chain with finger backward, to shorten by backguy power transmission pressuring spring, brush finish becomes spill; When brush was inboard, as long as a loose push-and-pull chain, spring extended automatically, and brush finish promptly becomes convex.

Advantage of the present utility model is: (1) is easy to use, has satisfied the different needs of people when brushing teeth the tooth inboard and the outside.(2) deformable bristle fixed block and make the design of this fixed block anamorphic attachment for cinemascope play the effect that changes the brush finish shape.

Below in conjunction with accompanying drawing concrete structure of the present utility model and operating position are described.

Working condition when Fig. 1 is the cleaning tooth outside

Working condition when Fig. 2 is cleaning tooth inboard

As shown in Figure 1: this toothbrush comprises handle 6, bristle 5, brush holder 7, and brush holder is made up of spring 3, bristle fixed block 4, backguy 2, and an end of backguy 2 is fixed on the bristle fixed block 4, and the other end is fixed on the push-and-pull key 1, draws 2 by brush holder 7 change directions.

During the cleaning teeth outside, pull back push-and-pull chain 1, give bristle fixed block 4 by stay cord 2 power transmissions, pressuring spring 3 shortens, and make bristle fixed block 4 be depression, thereby the brush finish of bristle 5 also is spill, and the structure of brush finish energy and tooth is coincide.

As shown in Figure 2: when the cleaning tooth is inboard, unclamps push-and-pull chain 1, spring 3 and extend automatically, make bristle fixed block 4 convexs, thereby make bristle 5 brush finish also be convex, the structure of brush finish energy and tooth is matched.
