Abstract

The utility model relates to an electric tooth brush, between the output shaft of the electric motor and the brush handle of which a operating device is arranged, which drives the brush handle and the brush head to do a reciprocate swinging. With such a manner of tooth brushing, grimes between the teeth spaces are easily cleaned off, the teeth are prevented from being damaged. Meanwhile the swinging of the brush bristles is achieved through only an eccentric shaft and follows up means, which is a relatively simple structure. The brush bristles are conveniently replaced which further saves the use-cost and prolongs the service life of the tooth brush.

Description

A kind of electric toothbrush

Affiliated technical field

This utility model relates to a kind of apparatus of washing one's face and rinsing one's mouth that is used for cleaning teeth, especially relates to a kind of by housing be installed in the electric toothbrush that intravital power supply and the motor of shell constituted.

Background technology

Toothbrush is employed a kind of utensil that is used for cleaning teeth in people's daily life.Traditional toothbrush is made of brush holder and the bristle that is installed in the brush holder end, scrubs tooth and finishes by bristle.But, because the brush holder of the toothbrush of this kind structure is flat basically, and bristle is directly installed on the end of flat-shaped rod member, so, the teeth brushing way that uses this kind toothbrush most convenient is that the direction along tooth arrangement laterally back and forth spurs in the oral cavity, and vertically rotary type is brushed teeth.But medical circle thinks that the residue on the tooth mainly between the slit of adjacent two teeth, is brushed teeth and should be advisable vertically to brush teeth.

For this reason, CN1187341A has announced the technology that a kind of name is called " electric toothbrush ", this electric toothbrush has a handle, in handle, be provided with battery and motor deceleration mechanism, also be provided with motor switch on the handle, on brush holder, also be provided with adjustable driving mechanism of drive form and TRAJECTORY CONTROL mechanism, driving mechanism is to be rotated synchronously by the eccentric stiffener that at least two of driven in synchronism gear drive parallel, and TRAJECTORY CONTROL is an active synchronization control gear of selecting button by having, under the effect of spring, be meshed with driven Synchronization Control gear and the lock gear that is fixed on the housing simultaneously, and be provided with and make up the sliding tray brush that chute is complementary with eccentric component coaxial line synchromesh gear axle head, make brush produce variable movement locus, from above-mentioned situation as can be seen, the structure of this kind electric toothbrush is quite complicated, do not have suitable volume that each associated components can't be installed, and then cause the raising of cost of manufacture.

In addition, CN1379643A has announced the technology that name is called " toothbrush with vibrating head part ", this toothbrush is loaded with the head that ranks forefront of bristle by a shank and, shank links to each other by cervical region with head, in head, settled a mechanical vibrator that can make head vibration, this vibrating device links to each other through the electric connection line that extends in the cervical region, this toothbrush is owing to be to making head thicker at head installing mechanism vibrating device, make oral sensation uncomfortable when brushing teeth, and, this toothbrush handle part surface irregularity be difficult for making, and profile is not attractive in appearance.

Summary of the invention

The purpose of this utility model provides a kind of electric toothbrush that utilizes simple structure just can realize and vertically brushing teeth.

The electric toothbrush that this utility model proposed, housing with a double as brush holder, the motor that power supply is installed successively and is electrically connected with this power supply in this housing is provided with between the output shaft of motor and brush holder support and can drives the operating mechanism that brush holder support and brush are done reciprocally swinging.

The end of described housing is provided with a radially inner projection, and brush holder support and the corresponding position of this projection are provided with and can allow that projection passes and can make the shrinkage pool of brush holder support around its place plane rocking.

Described operating mechanism has an axial eccentric shaft that is arranged on the motor output shaft, but and be provided with the servo-actuated member that the allowable offset axle is put in the brush holder support end, the end of eccentric shaft is spherical or oval, and described servo-actuated member be can allow that sphere or oval eccentric shaft are put into and with perpendicular three opening grooves of brush holder support.

Described operating mechanism also has in three opening grooves that are arranged on the servo-actuated member and can do the middle secondary of reciprocally swinging within it by what bearing pin limited, be provided with a rectangular channel in the subsidiary central region in this centre, eccentric shaft be provided with one that can swing with the rotation of this eccentric shaft and can extend in the middle of slide block in the secondary rectangular channel.

The cross section of described housing is the rectangle that two semiellipses or rib place have chamfering.

The end of described brush holder support is provided with dovetail, and the face that brush is connected with brush holder support is provided with dovetail groove.

Described operating mechanism has an axial eccentric shaft that is arranged on the motor output shaft, this eccentric shaft is provided with a connecting rod perpendicular with it, and the tail end of brush holder support has a kink, and the servo-actuated member that is made of the open type groove is installed on this kink.

The electric toothbrush that this utility model proposed can make bristle along the place plane rocking, and this teeth brushing way is easy to the dirt between the cleaning teeth seam, and does not damage tooth; The structure of eccentric shaft and servo-actuated member is only adopted in bristle swing simultaneously, and its structure is simple relatively; In addition, because of bristle can be changed easily, can further save the service life of use cost and prolongation toothbrush.
