Description

Electric cleaning brush

Technical Field

The utility model relates to an articles for daily use technical field especially relates to an electric cleaning brush.

Background

As the demand of society is continuously increasing, tools for cleaning teeth, including manual toothbrushes, electric toothbrushes, etc., are continuously advancing.

The manual toothbrush has an advantage of low cost, but has a disadvantage of poor cleaning effect.

The existing electric toothbrush has better cleaning effect than a manual toothbrush, but the brush head of the existing electric toothbrush usually adopts a high-frequency vibration mode to clean teeth, and has the following disadvantages:

(1) the high-frequency vibration mode has very high vibration frequency, and the tooth surface contacted by the brush head is easy to be excessively cleaned, so that the tooth surface is excessively abraded and damaged; in addition, due to the fact that the frequency is too high, the vibration effect of the brush head is very strong, when the toothbrush is used by people, oral cavity itching and numbness can be caused, retching can easily occur, and the toothbrush cannot be used by many sensitive people.

(2) The vibration amplitude of the brush head is very small, the texture of the bristles is soft, and the brush head has the characteristic of being capable of bending and deforming, when the tip of the bristles contacts with the tooth surface, the brush head only vibrates, and the tip of the bristles cannot have any cleaning action, so that the tooth grooves and the tooth gaps cannot be cleaned, and the cleaning effect is poor.

(3) The electric toothbrush vibration sense of the high-frequency vibration mode is very strong, and in the using process, the hand is held by the hand and the vibration sense is very strong, so that the hand discomfort is easy to occur, in addition, the noise is very large, and the use experience of a user is greatly reduced.
