CN2190976Y - Electric toothbrush - Google Patents

Abstract

The utility model relates to an electric toothbrush which is used in daily life. The utility model is characterized in that the head part of a shaft core of an electric motor (6) which is arranged in an oscillating body (2) is provided with a piece of eccentric block (5). The utility model not only can clean tooth surface, but also can clean tooth gap to effectively remove mycoderma on the tooth surface without damaging gum. The tooth brush can be disassembled into three sections in order to be convenient to carry, maintain, change a battery and change an old toothbrush head. The electric toothbrush has the advantages of simple structure, easy manufacture, low cost and easy popularization.

Description

Electric toothbrush

This utility model relates to the electric toothbrush that daily life is used.

At present, the kind of commercially available tooth brush for health protection is a lot, and wherein a kind of electric toothbrush can be imitated upper and lower swing of artificial action or rotation, and this toothbrush can be removed the dirt of dental surface, and the health of tooth has been played positive role.But dirt and the food waste of this class toothbrush to retaining in the interval of tooth, the dental surface Mycoderma but can't be removed.

The purpose of this utility model provides a kind of teeth surfaces of not only wanting, and wants the toothbrush of while energy cleaning teeth slit and tooth surface Mycoderma.

Technical solution of the present utility model is on the basis of the head toothbrushes of existing electric toothbrush, handle, battery, motor, spring, switch, conductive reed, and particularly the axle core head at the intravital motor of vibration is fixed with an eccentric block.

Operation principle of the present utility model is a pull switch, conductive reed is contacted with the motor contact, and spring, battery, motor, reed constitute closed circuit like this, and motor is promptly started working, the motor shaft core rotates, and the eccentric block that is fixed on the motor shaft core head also rotates thereupon.When the motor high speed rotating, eccentric block has produced uniform centrifugal force, formed the altofrequency vibration, and be delivered on the toothbrush bristle, at this moment toothbrush has produced resonance, this resonance is to be determined by the motor of the vibration source of high frequency, eccentric block, the length that reaches removable toothbrush and quality, this vibration causes softish bristles moving at tooth surface, and enter slit between tooth and the tooth, thereby very effectively from the surface breakdown of tooth with remove softish Mycoderma and residue, and can not damage periodontal soft tissue.

Both the utility model has the advantages that can teeth surfaces, also can the cleaning teeth slit, remove the facing Mycoderma effectively, do not damage gingiva, it is three sections that toothbrush also can be taken apart easily, be easy to carry, keep in repair, change battery and old head toothbrushes, simple structure is easy to processing, with low cost, is easy to promote.

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

Fig. 1, organigram of the present utility model.

Embodiment one,

According to shown in Figure 1, this utility model has a spring that is connected the end of with (8) in handle (3), spring (8) joins with battery (7), at handle (a 3) pendulum of front end socket (2), pendulum (2) internal fixation a motor (6), motor (6) tail end contact and battery (7) positive pole join, motor (6) axle core head is fixed an eccentric block (5), go up a switch (4) in addition at pendulum (2), switch (4) joins with electric conductivity reed (9) one ends, and conductive reed (9) other end is connected with spring (8).Pendulum (2) front end can be refuted mutually with head toothbrushes (1) and be connect.Switch of the present utility model (4) forces conductive reed (9) one end perks and motor (6) upper contact to join when shifting certain position onto, conductive reed (9), spring (8), battery (7), motor (6) are formed closed circuit at this moment, motor (6) promptly begins to run up, the eccentric block high speed rotating produces dither thereupon, and produces resonance with head toothbrushes (1).

Claims (5)

1, a kind of electric oscillation toothbrush, comprise head toothbrushes (1), handle (3), motor (6), battery (7), spring (8), switch (4), conductive reed compositions such as (9), it is characterized in that the axle core head of the motor (6) in pendulum (2) is fixed with an eccentric block (5).

2, electric oscillation toothbrush according to claim 1 is characterized in that head toothbrushes (1) is that removable refuting mutually with pendulum (2) connects.

3, electric oscillation toothbrush according to claim 1 is characterized in that pendulum (2) internal fixation has motor (6), and pendulum (2) is that removable refuting mutually with handle (3) connects.

4, electric oscillation toothbrush according to claim 1 is characterized in that handle (3) internal fixation has battery (7), and battery (7) negative pole can join with handle (3) the fixed spring in bottom (8).

5, electric oscillation toothbrush according to claim 1 is characterized in that switch (4) is arranged on the pendulum (2), and can join with conductive reed (9).
