Rolling type electric toothbrush

Abstract

The invention relates to a rolling type electric toothbrush, aiming at overcoming the defects that the existing electric toothbrush can clean the surfaces of teeth in a way of plane rotation, thus easily causing abrasion to the surfaces of the teeth and damaging tooth protection surfaces. According to the rolling type electric toothbrush, a brush head is connected with a brush handle in a way of position-convertible inserting connection; the brush head comprises a brush body having a revolving body structure, and bristles arranged on the whole peripheral surface of the brush body; the bristles are vertical to a rotating axis of the brush body; a rotary brush surface which is in an arc shape along the rotating axis of the brush body is formed at the ends of the bristles. The bristles are arranged on the whole peripheral surface of the brush body, and the bristles on the brush head are vertical to the rotating axis of the brush head, so that the surfaces of the teeth are cleaned by the bristles in a rolling way, and the rolling type electric toothbrush is less in damage to the surfaces of the teeth; when the rolling type electric toothbrush is in use, the brush head is parallel to the surfaces of the teeth, and the direction of movement of the bristles relative to the surfaces of the teeth is consistent with those of gaps among teeth, so that the cleaning effect is improved, and the abrasion to the surfaces of the teeth is reduced.

Description

technical field [0001] The invention relates to an electric toothbrush, in particular to a rolling electric toothbrush. Background technique [0002] The mouth is the first pass of the human digestive system, and the teeth are the necessary organs for people to chew food. There is only one set of permanent teeth in a person's life, and caries and periodontal disease are the most common diseases of teeth. Caries is one of the three major chronic diseases that must be prevented and controlled by the World Health Organization, and periodontal disease is the main cause of tooth loss. An effective way to prevent dental caries and periodontal disease is to brush your teeth effectively. [0003] Brushing your teeth is mainly to remove the residue on the tooth surface by rubbing back and forth on the tooth surface with the bristles of the toothbrush, and clean the bacterial plaque adhered to the tooth surface. Plaque is the initiating factor of caries and periodontal disease. ...

AI Technical Summary

Problems solved by technology

[0007] The invention solves the defect that the existing electric toothbrush cleans the tooth surface in a plane rotating manner, which is easy to cause wear on the tooth surface and damage the tooth protection surface, and provides a rolling electric toothbrush, the bristles on the brush head are perpendicular to the rotation axis of the brush head , so that the bristles clean the tooth surface in a rolling manner, with little damage to the tooth surface

[0008] The present invention also solves the defect that there is only one connection angle between the brush head and the handle of the existing toothbrush, which cannot adapt to the cleaning needs of changes in the growth position of the teeth, and provides a rolling electric toothbrush. The insertion position of the brush can be converted, and the angle between the brush head and the handle changes after conversion, so as to adapt to the change of the tooth growth position

[0009] The invention also solves the defect that the bristles of the existing electric toothbrush are basically parallel to the rotation axis of the brush head, and the brush head is kept perpendicular to the surface of the teeth during use, which makes it more difficult to clean the buccal and distal surfaces of the teeth, and provides a Rolling electric toothbrush, the bristles are perpendicular to the rotation axis of the brush head. When in use, the brush head is kept parallel to the tooth surface, which can effectively clean the buccal and distal surfaces of the teeth
