Vertical-brushing dual-head electric toothbrush

Abstract

The present invention relates to a vertically-brushing type two-head electric tooth-brush. Said tooth-brush includes front and rear two brush heads which are mounted in the front part of tooth-brush handle and can be linearly moved leftwards and rightwards and a connecting bar component mounted in the internal cavity of tooth-brush handle, and the front end of said connecting bar is connected with driving wheel which is rotatably and movably connected on the lower cover of tooth-brush handle, and the back face sides of the described front and rear brush heads which are opposite to the driving wheel are equipped with shifting keys which can be fallen into the front and rear recessed grooves, of the driving wheel. Its electric device utilizes connecting bar to drive driving wheel, and said driving wheel can utilize two shifting keys to drive front and rear two brush heads to make them implement up and down alternative reciprocating movement.

Description

technical field [0001] The invention relates to a toothbrush for daily use, in particular to an electric toothbrush driven by an independent power supply. Background technique [0002] Existing electric toothbrushes, the brush head is either a rotating brush head, and the bristles rotate forward and backward around the toothbrush handle. Although it can effectively remove the dirt on the surface of the teeth, it is difficult to remove the dirt in the gaps between the teeth, and its trajectory is an arc. , does not meet the recommended vertical tooth brushing method along the tooth growth direction; or it is a swinging brush head, the bristles swing back and forth perpendicular to the direction of the toothbrush handle, which can effectively remove the dirt in the teeth, but it needs to be fully cleaned. Spend more time, and the efficiency of brushing teeth is not high either. Contents of the invention [0003] The technical problem to be solved by the present invention is...
