Description

Electric vibrating toothbrush

Technical field

Apparatus technical field, particularly electric toothbrush technology field the present invention relates to brush teeth.

Background technology

The cleaning of tooth has very big effect to the health of human body, crowd's contacts.As the toothbrush of brushing tool, play a big part again for the cleaning of tooth, protection.

Electric toothbrush, promptly when the people brushes teeth, toothbrush self has the motion or the vibration of rule, has played assosting effect to brushing teeth, and, clean-up performance to tooth, particularly, goodish effect is arranged, according to statistics to the cleaning of tartar, tartar, use electric toothbrush than using ordinary toothbrush, cleaning effect 80%.

Electric toothbrush has emerged for a long time, and electric toothbrush in the market is of a great variety, is on the basis of ordinary toothbrush, and configuration power supply and micromachine mainly are divided into rotary-type and vibration type two classes.

Rotary-type is the configuration tumbler, drive with micromachine, make toothbrush head do motion clocklike, cooperation is brushed teeth, its shortcoming is: the correct operation of brushing teeth should be moving along the upper and lower brush of teeth space, and the toothbrush head of this type is multiple, a closed trajectory motion, often brushes the part that should not brush, cross the surface of tooth etc. such as gingiva, horizontal scrubbing brush, can cause bad influence to tooth on the contrary.

The vibration type is that vibration source is set on toothbrush, produces vibration when brushing teeth, and makes attached to loose or dislocations such as the stain of the tooth on the tooth, tartar, and the effect of fine decontamination and massage dental bed is arranged.But, the brush of in the market this kind of electric toothbrush is hard the connection with handle, vibration that vibration source produces like this, the hands of being held the user of this toothbrush handle mostly balances out, and do not concentrate on brush, and reduced the brush teeth effect of decontamination of this toothbrush widely, cause the discomfort of user hand simultaneously.

Summary of the invention

The purpose of this invention is to provide a kind of electric toothbrush, this electric toothbrush in use, the vibration that vibration source is produced farthest concentrates on brush, the hands of not held this toothbrush handle user as much as possible balances out.Another object of the present invention provides a kind of electric toothbrush, this electric toothbrush can be easily more changing brush head or vibration source.

The technical scheme that realizes the object of the invention is: a kind of electric vibrating toothbrush comprises brush; The electric switch of control power connection and disconnection; With the handle that described brush is connected away from hairbrush one end, in described brush, be provided with a vibration source by power drives; Described brush and described handle interconnect by a flexible body.

Form oneself and the cavity that the flexible body link extends to described hairbrush end in the described brush, described vibration source is arranged in the described cavity.

Described electric switch is arranged on the described handle.

Described vibration source has the eccentric that driven by a micromachine.

Described cavity extends to the hairbrush position of described brush, and described eccentric is arranged near in the described cavity at hairbrush position.

In described handle, be provided with handle cavity, drive the described micromachine of described vibration source and be arranged in the described handle cavity as the battery of power supply.

Described brush comprises the front portion and is connected rear portion between described front portion and the flexible body; Described vibration source is arranged in the cavity at described rear portion; In described handle, be provided with handle cavity, drive the described micromachine of described vibration source and be arranged in the described handle cavity as the battery of power supply.

Described brush comprises the front portion and is connected rear portion between described front portion and the flexible body; Described micromachine and described eccentric are arranged in the described forward cavity; In described handle, be provided with handle cavity, described electric switch and be arranged in the described handle cavity as the battery of power supply.

Described brush comprises the front portion and is connected rear portion between described front portion and the flexible body; Described cavity extends to the described forward described hairbrush position of described brush, and described eccentric is arranged near in the described cavity at hairbrush position; The described micromachine of described vibration source is arranged in the described cavity at described rear portion of described brush; In described handle, be provided with handle cavity, be arranged in the described handle cavity as the battery of power supply.

Be provided with sealing ring between the described front portion of described brush and the described rear portion.

The present invention has positive effect: (1) is owing to be provided with flexible body between vibration source and handle, flexible body can play the effect that cushions even intercept vibration between vibration source and handle, the vibration that can effectively make vibration source and produced farthest concentrates on toothbrush head, and the hands of not held this toothbrush handle user as much as possible balances out.。(2) vibration source can directly be provided with in the brush, because vibration source and brush hairbrush are at a distance of nearer, so vibrating effect is better; (3) when brush comprises the front portion and be connected rear portion between described front portion and the flexible body, owing to can dismantle between the front and rear, conveniently replaced brush or vibration source are saved use cost, and are convenient to maintenance.
