Abstract

The utility model relates to a brush head rotating toothbrush, which comprises a toothbrush head and a toothbrush handle. The toothbrush head is a rotating body; the toothbrush handle is connected with the toothbrush head through a driving mechanism. The utility model adopts mechanical driving and changes the reciprocating movement of the toothbrush handle into the rotating movement of the toothbrush head; the brush head rotating toothbrush can realize the simultaneously scrubbing of the inner side and the outer side of teeth and the scientific method of brushing the teeth along tooth gaps. The utility model has the advantages of high efficiency, tooth cleaning, and gingiva massaging.

Description

The brush rotary tooth-brush

This utility model is a kind of brush rotary tooth-brush that rotatablely moves that becomes the reciprocating motion of handle into head toothbrushes.

Commercially available toothbrush all is the fixed straight-bar toothbrush of brush at present, often get used to laterally brushing teeth with this toothbrush people, vertically brush teeth and feel inconvenience, for carrying out brushing teeth easily along teeth space, someone has released electric toothbrush, and it is to drive the head toothbrushes rotation according to battery or external power supply drive motors, brushes teeth though it has made things convenient for vertically, in case but dead battery or do not have the place of external power supply has produced new inconvenience again.

The purpose of this utility model is, for overcoming the deficiency of prior art, provide a kind of need not power drives, the brush rotary tooth-brush that convenience simple in structure is brushed teeth along teeth space.

Following mode can realize this utility model:

The brush rotary tooth-brush comprises brush, brush holder, and brush is a rotary body, and brush holder connects brush through driving mechanism.

Brush be two hollow round table-like, have a plurality of on the round platform outer wall along the wall slideway in one week, be fixed with bristle on the outer wall except that slideway, the round platform inwall upwards is provided with the helical form slideway end of from, the brush holder front end is divided into the end that two push rods insert the end of two round platform inwall slideways respectively, and can slide along the helical form slideway, fixing head both sides are respectively stretched out a plurality of dogs and are inserted along in the round platform outer wall slideway in one week.

Brush holder connects a support, two axles are arranged on the support, go up two driving gears of installation near the axle of bracket edge, driving gear exposes the support outer rim, be equipped with driven pulley gear and an end tooth wheel of being meshed with driving gear on another, one spur gear and the engagement of end tooth wheel, brush is installed on the straight-tooth wheel shaft.

This utility model becomes rotatablely moving of head toothbrushes to the reciprocating cutter of living of handle, and be beneficial to and promote the science method for brushing teeth of brushing teeth along teeth space, massage gingiva in the cleaning teeth surfaces externally and internally, easy operating, and brush is replaceable.
