A string vibrating silent sonic electric toothbrush head

Abstract

The invention discloses a string vibration type mute sound wave electric toothbrush head, which comprises: a brush head body, which is used for installing bristles and connecting the main body part of the brush body; Connect; the string vibration device is arranged inside the brush head body and connected with the toothbrush driving mechanism, and is used to drive the vibration of the bristle assembly; the string vibration device includes a vibration rod assembly and a vibrating body connected with the vibration rod assembly, the described The vibrating body is arranged in the form of strings between the brush head body and the bristle assembly, and a gap is provided between the vibrating body and the bristle assembly. The vibrating body of the string vibrating silent sonic electric toothbrush head is arranged in a string structure. After vibrating at high frequency, the vibrating body directly acts on the bristle assembly. When cleaning teeth, only the bristle assembly is vibrated, while the brush head body remains relatively still without vibration , will not damage the teeth due to high-frequency vibration caused by contact with hard teeth, effectively reducing the damage to the teeth.

Description

technical field [0001] The invention relates to the technical field of electric toothbrushes, in particular to a string-vibration silent sonic electric toothbrush head. Background technique [0002] Because the traditional electric toothbrush head uses an ultrasonic motor to drive the entire toothbrush head to vibrate, it is easy to cause damage to the teeth during use. Simultaneously, when the ultrasonic vibrating toothbrush in the prior art is brushing teeth, both the brush head and the fuselage will vibrate, and there is poor tooth cleaning effect, vibration sound wave frequency, vibration intensity and brush head power are low, and the problem of big noise. Therefore, there is an urgent need to design a design that can not only reduce or eliminate the vibration of the non-bristle part of the base, but will not damage the teeth due to high-frequency vibration caused by contact with hard teeth, and can also strengthen the vibration amplitude, improve safety and comfort, an...

AI Technical Summary

Problems solved by technology

[0005] The present invention overcomes the ultrasonic vibrating toothbrush in the prior art when brushing teeth, both the brush head and the body will vibrate, which will easily cause damage to the teeth, poor tooth cleaning effect, low frequency of vibration sound waves, low vibration intensity, and low power of the brush head. In order to solve the problem of high noise, a strong string mute sound wave electric toothbrush head is provided. By setting an electric toothbrush with a string vibration device, the toothbrush only vibrates the bristles and does not vibrate the shell during use, even if the brush head is not The bristles directly touch the teeth, and will not cause high-frequency vibration to damage the teeth due to contact with hard teeth. At the same time, the vibration amplitude is strengthened, the safety, comfort and cleaning power are improved, and the waste of vibration energy is reduced. It increases the battery life of the electric toothbrush, increases the vibration frequency and strength of the brush head, increases the cleaning effect, and is more silent
