Description

A kind of electric toothbrush using metal locating plate control motor rotational angle

Technical field

The utility model relates to electric toothbrush technology field more particularly to a kind of use metal locating plate control motor rotations The electric toothbrush of angle.

Background technique

The problems such as focusing on dental health and beauty with more and more people, the crowd that electric toothbrush uses gradually increases, Basic principle is the quick rotation or vibration by electric core, so that brush head is generated high-frequency vibration, moment resolves into toothpaste carefully Microfoam deeply cleans teeth space, and at the same time, the trembling of bristle can promote the blood circulation in oral cavity, has massage to gingiva tissue Effect.

Existing electric toothbrush divides from basic principle, there is two major classes: i.e. rotation and vibration.The toothbrush of rotation class passes through electricity Machine drives round brush head rotation, reinforces friction effect while executing common brushing action, the toothbrush noise for rotating class is big, tooth Face cleaning is very clean, and teeth space cleaning is relatively weak but big to tooth wear, it is not recommended that is used for a long time；Vibrate the interior of class There is an electrically driven (operated) vibrating motor, brush head can be allowed to generate the swing in high frequency perpendicular to brush handle direction, swing in high frequency when brushing teeth Brush head can efficiently be completed to scrub the movement of tooth, can also go deep into teeth space cleaning dirt.

For electric toothbrush, current electric toothbrush belongs to the tool of cleaning tooth, by rechargeable cell, miniature Direct current generator, battery case, head toothbrushes and sleeve composition, dry cell and direct current generator as DC motor power are installed along with There is the manual switch of control DC motor power on-off in battery case, on battery case, DC motor shaft stretches out outside battery case.

Since the cleaning effect of electric toothbrush obtains actual verification already, have a wide range of applications, those skilled in the art It is analyzed also for existing electric toothbrush in relation to the defect of driving device well-known technique:

Firstly, general electric toothbrush is using magnetic d.c. motor is commonly sharpened as power, driving head toothbrushes are swung or rotation, Major defect is: 1. motor speed bottom is low, revolving speed about 4000~6000RPM when generally working normally；2. driving torque is small (generally about 60g*cm)；3. electric current becomes larger (0.4~1.2A) with the increase of load when motor operations；4. motor noise is big, the service life is short.

Meanwhile existing electric toothbrush is unable to ensure and injures gum because of pivot angle reason when brushing teeth；

In addition, current electric toothbrush display mode is relatively simple, all indicated using LED display, it is clear to lack Intuitive mark gear.

In conclusion the utility model is exactly on the basis of existing well-known technique, in conjunction with the verifying of practical application, to same Product structure in one technical field proposes that further research and development and improved technical solution, the technical solution that these are proposed are complete Can satisfy and prior art defect is made up, at the same be also beneficial to numerous technical problems of same technical field solution and The expansibility for the scheme that develops skill.
