Problems solved by technology

[0002] The brush head of the existing electric toothbrush has only one side of bristles. Since the upper and lower rows of teeth are convex, the upper side and inner side of the teeth are not easy to clean effectively, and it is easy to form a blind spot for brushing teeth; when brushing teeth, the teeth must be cleaned by rubbing the tooth surface with the bristles However, the existing electric toothbrush can only vibrate or rotate the bristles on one side of the brush head through the motor, and the cleaning effect on the teeth is not good. It needs to change the direction of the brush head many times to clean the outside, inside, and molar surface of the teeth, which is time-consuming and laborious. , and it is easy to form bad brushing habits

Abstract

The invention relates to the mechanical field, in particular to a brush head of an electric toothbrush. An electric toothbrush brush head adopting torsion springs comprises a brush head, and the brush head includes a brush head handle, a front brush plate, a rear brush plate, and an upper brush plate. Through this design, the present invention provides an electric toothbrush head using a torsion spring. The motor drives the three-sided bristles of the brush head to move, which improves the cleaning effect of the teeth; The thickness of the molars changes, and the self-adaptive effect of the bristles automatically fit to meet the teeth cleaning needs of people with different mouths and tooth sizes. The design of the three-sided bristles solves the problem of cleaning the areas that are not suitable for brushing on the inside of the teeth, and avoids various bad brushing habits. produce, simplify the process of brushing teeth, and improve the efficiency of brushing teeth.
