Description

Electric three-face toothbrush Technical Field The utility model relates to the technical field of three-face toothbrushes, in particular to an electric three-face toothbrush. Background Most people brush teeth along the directions of upper teeth and lower teeth by a transverse brushing method, and the traditional toothbrush only uses one brush surface, which means that a user needs to adjust the brushing posture back and forth to ensure that the three surfaces of the teeth are brushed cleanly. The toothbrush and the brushing mode brought by the toothbrush lead to low brushing efficiency, so the three-face toothbrush is provided, three-face cleaning work on teeth can be simultaneously finished at one time, which is equivalent to reducing the brushing time by 2/3, and the toothbrush is time-saving and convenient to use. The traditional Chinese patent with publication number of CN219479466U and name of three-face toothbrush can only manually and rapidly move the three-face toothbrush back and forth to achieve the effect of brushing teeth on three faces, and the mode of brushing teeth does not have the characteristics of convenience and labor saving of an electric toothbrush. There is a great need for an electric three-sided toothbrush that can achieve an electric brushing effect. Disclosure of utility model The utility model aims to provide an electric three-sided toothbrush, which solves the problem that the existing three-sided toothbrush can only move back and forth manually and rapidly so as to achieve the effect of brushing teeth on three sides and has no electric function. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides an electronic trilateral toothbrush, includes handle, trilateral brush head, micro motor, battery, gear assembly, flexible axle and brush roller, the handle with trilateral brush head is connected, micro motor the battery with the gear assembly all set up in the handle, the battery pass through button switch with micro motor electricity is connected, micro motor's power take off end with gear assembly's power input end is connected, the brush roller rotates respectively and installs on the three brush face of trilateral brush head, a plurality of the flexible axle set up in the trilateral brush head, one the flexible axle is connected respectively one power take off end of gear assembly with one the power input end of brush roller is connected. The technical scheme is that a section groove is arranged among three brushing surfaces of the three-surface brush head. The gear assembly comprises a gear disc, a driving wheel, driven wheels and a central shaft, wherein the gear disc is arranged in the handle, the driving wheel and the three driven wheels are rotatably arranged on the gear disc, the driving wheel is meshed with the three driven wheels, the power output end of the miniature motor is connected with the power input end of the driving wheel, the three central shafts are respectively arranged at the centers of the three driven wheels, and the three central shafts are respectively connected with the three flexible shafts. The further technical scheme is that the diameter of the driving wheel is smaller than that of the driven wheel. The technical scheme is that brushing surfaces on two sides of the three-side brush head are arranged in an outward inclined mode. The three brushing surfaces of the three-surface brush head are provided with accommodating grooves matched with the brush rollers. Compared with the prior art, the utility model has at least one of the following beneficial effects: The utility model provides an electric three-sided toothbrush, which solves the problem that the traditional three-sided toothbrush needs to be manually moved back and forth to realize tooth brushing, and can drive the three-sided brush rollers on the three-sided brush head to rotate together in a matched manner by virtue of a miniature motor, a gear assembly and a flexible shaft so as to achieve the effect of automatically brushing three sides of teeth, thereby being convenient and labor-saving.
