Abstract

The utility model relates to a toothbrush used by human beings in daily life, particularly a tooth motion type toothbrush driven by teeth. The toothbrush is respectively provided with a couple of drum type brushes in the upper and the lower sides, a fourth pinion in a chute is driven to roll from top to bottom via strip-shaped racks on a transverse plate and drive a series of gears to rotate in order to drive the upper and the lower couples of drum type brushes to rotate internally all the time and achieve to brush teeth correctly in sequence. The utility model has the advantages of novel structure, easy use, good effect, etc.

Description

Gear-driving toothbrush in tooth motion

This utility model relates to human toothbrush used in everyday, particularly is the geared toothbrush of power with the tooth opening and closing.

The toothbrush that uses in people's daily life, have manually, it is several that electronic and tongue is moving etc., major defect is correct suitable brush method for brushing teeth, must and adhere to through study using and to form gradually, and dental bed is inboard and rear side is difficult for outwash, especially manual toothbrush, the power that not only needs hands also can be usually owing to the improper oral cavity of damaging of dynamics control.

The purpose of this utility model is just in order to solve the problem of above-mentioned existence, and design a kind of opening and closing that rely on tooth self, driving toothbrush brushes teeth by correct suitable brush method for brushing teeth, this toothbrush can remain correct method for brushing teeth, and reach the liberation both hands by the activity of tooth, proofread and correct helical teeth, build U.S. facial auxiliaring effect.

The purpose of this utility model realizes that by following technical proposal this toothbrush comprises hairbrush, it is characterized in that:

A, an end are engaged on the strut (5,6), and the other end is fastened on upper and lower on first pinion (7,8) respectively a pair of drum-type hairbrush (1,2,3,4),

Being fastened on the same axle (31,32) of b, first pinion than gear wheel (9,10) and second pinion (11,12),

The gear wheel of c, second pinion (13,14) and than flexible connecting rod (35,36) between the gear wheel, and be fastened on same axle with third pinion (15,16) and go up (33,34),

One of d, third pinion engagement be fastened in the rotating shaft than pinion (17,18).Answer a fourth pinion (19,20) that is fastened in the rotating shaft with third pinion with than pinion mate.

E, fourth pinion are meshed with third pinion with than pinion respectively, and the strip tooth bar (23,24) that connects with transverse slat of engagement,

F, the chute (21,22) that on dividing plate, has the confession fourth pinion to slide,

G, two transverse slats (25, the 26) bottom that connects with spring (29,30) have the surface to be with the boss (27,28) of dimpled grain

Owing to take technique scheme, make to the utlity model has novel structure, easy to use, have the helical teeth of correction and vigorous and graceful effect.

Description of drawings:

Accompanying drawing is this utility model structural representation.

Below in conjunction with accompanying drawing this utility model is further described:

When using this toothbrush, earlier tooth is stung at transverse slat (25,26) boss (27,28) on, interlock then is last, under the effect of lower teeth, strip tooth bar (23,24) can drive fourth pinion (19,20) along chute (21,22) slide into than on the pinion (17,18), driving changes outward than pinion, change in less gear driven third pinion (15,16) and the gear wheel (13,14), gear wheel drives second pinion (11,12) and changes than gear wheel (9,10) is outer, drive first pinion (7,8) and drum-type hairbrush (1,2 than gear wheel, 3,4) change in, hairbrush is formed along brush, when tooth opens, because volute spring (29,30) tension force, strip tooth bar can drive fourth pinion and slide on the third pinion (15,16) along chute, driving in third pinion and the gear wheel changes, thereby make first pinion and roller brush still keep interior commentaries on classics, realized correct along brushing, because flexible connecting rod (35,36), the tooth thickness all can adapt to.
