Abstract

The utility model discloses a toothbrush which comprises a brush head 6, a brush rod 2 and a brush holder 4, wherein the outer surface of the circular brush head 6 or the polygonal brush head 6 is provided with brush bristles 5; the brush rod 2 which is connected with the brush head 6 is penetrated in a center hole of the brush holder 4 in a rotary mode, and is connected with a driving mechanism arranged at the end part of the brush rod 2; one end of the brush holder 4, which corresponds to the brush head 6 is connected with a lip protecting plate 1. The driving mechanism is controlled to drive the brush head 6 to rotate, so the brush head 6 can rotate along gaps among teeth to clean food residue accumulated in the gaps and scale deposit formed on tooth surfaces. Thereby, the toothbrush can conveniently and clearly clean the teeth without hurting the teeth.

Description

A kind of toothbrush

The utility model relates to daily living article, is specifically related to people's toothbrush for toothbrushing.

At present; normally used toothbrush in the society; generally all be that bristle places the brush side; when brushing teeth; people operate brush and laterally brush teeth perpendicular to slit between tooth, and deficiency is: be difficult to and will remain in the swill outwash in the slit between tooth, firmly clean with water also easily to brush and hinder gum; perhaps destroy the tooth glaze on the surface that takes care of one's teeth, cause tooth to meet cold sour food hypersenstivity reaction pain.The teeth brushing way of science is to brush teeth in the slit of bristle along between tooth, but operation inconvenience, the slit of cleaning with water especially between the inboard food tooth of oral cavity is more difficult.

The purpose of this utility model be to provide a kind of can be easily and flexibly along between tooth the slit clean tooth incrustation with water and non-damage tooth is cleaned clean toothbrush again with water.

For achieving the above object, toothbrush of the present utility model is made up of brush, brush holder support and brush holder; Be provided with bristle in circle or polygon brush head outer surface, the brush holder support that links to each other with brush rotates in the brush holder mesopore, and links to each other with the driving mechanism that is located at the brush holder support end, and rotating drive mechanism just can drive the brush rotation, cleans tooth with water; With corresponding brush holder one end of brush, be provided with the lip care plate.

After adopting this structure, people can control driving mechanism easily and flexibly and drive brush and rotate, and realize that brush slit along between tooth rotates the incrustation that the swill of cleaning its internal memory with water and dental surface form, and clean with water totally and damage tooth not.

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

Fig. 1 is the cutaway view of first embodiment of the utility model;

Fig. 2 be among Fig. 1 A-A to profile;

Fig. 3 is with reference to brush (6) and lip care plate (1) profile of A-A among Fig. 1 to another kind of shape;

Fig. 4 be among Fig. 1 B-B to cutaway view;

Fig. 5 is the cutaway view of second embodiment of the utility model.

Embodiment one, with reference to Fig. 1-Fig. 4.Be injected with bristle 5 on circular brush 6 outer surfaces, the brush holder support 2 that links to each other with brush 6 rotates in brush holder 4 mesopores, and link to each other with the pinion 7 that is located at brush holder support 2 ends, internal gear 3 is rotationally connected with on the brush holder 4 by rotating shaft 8, and the pinion 7 and internal gear 3 gear teeth are meshed.With brush 6 corresponding brush holder 4 one ends, be connected with the circular arc lip care plate 1 that prevents to bump mill human body lip when cleaning tooth with water.Certainly, lip care plate 1 cross section can be designed to many prismatics (shown in Figure 3); Brush 6 cross sections also can be designed to quadrangle, hexagon, octagon polygons such as (shown in Figure 3); The forward and backward part of brush holder 4 is combined into one (shown in Figure 1) after can separately designing, also can an injection molded.These variations all drop within the protection domain of the present utility model.

During use, scribble toothpaste on the brush 6, hold brush holder 4 ends, make brush 6 laterally near dental surface, rotational inner gear 3 cylindrical C places, by the gearratio of gear wheel and pinion, accelerated the revolution of pinion 7, realized that brush 6 slit along between tooth is rotated to clean the swill of its internal memory and the incrustation of dental surface with water.

Embodiment two, with reference to Fig. 5.With embodiment one different be: little rubber wheel 12 connects and brush holder support 2 ends, and big rubber wheel 10 is rotationally connected with on the bearing 11 of brush holder 4 by bolster 9, and

little rubber wheel

12 and 10 liang of outer round surface of big rubber wheel contact by strain, form the friction transmission.Rotate big rubber wheel cylindrical C place and both can realize that brush 6 rotated.Certainly, also can select being connected with a joggle of corresponding gear wheel and pinion for use, the big rubber wheel 10 that replaces among Fig. 5 is connected with little rubber wheel 12, also belongs to protection domain of the present utility model.
