Surrounding toothbrush capable of maintaining position of brush hair on upper side

Abstract

The invention relates to the field of machinery and in particular relates to a surrounding toothbrush capable of maintaining the position of brush hair on an upper side. The surrounding toothbrush comprises an electronic toothbrush, wherein the electronic toothbrush comprises a brush head; the brush head comprises a brush head stem; an upper-side brush plate, a front-side brush plate and a rear-side brush plate are arranged at the front part of the brush head stem; the upper-side brush plate and the front-side brush plate are connected through a transmission mechanism; the transmission mechanism comprises an elastic connecting part for returning the front-side brush plate; and the elastic connecting part is arranged between the upper-side brush plate and the rear-side brush plate. Due to the designing, the invention provides the surrounding toothbrush capable of maintaining the position of the brush hair on the upper side, and through a surrounding effect achieved by brush hair on three surfaces and thickness variation from front teeth to cheek teeth, tooth cleaning demands of people of different sizes of oral cavities and teeth can be met through a self-adaptive effect of automatic fitting of the brush hair; and meanwhile, brush hair under the upper-side brush plate is maintained in a middle position at the upper part of teeth, the upper surfaces of the teeth can be well cleaned, and the cleaning effect can be improved.

Description

technical field [0001] The present invention relates to the field of mechanics, in particular toothbrushes. Background technique [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, it is necessary to change the direction of the brush head many times to clean The outer, inner, and molar surfaces of the teeth are time-consuming and laborious, and it is easy to form bad teeth brushing habits; or, there are some existing three-sided brushing toothbrushes. The bristles are relatively fixed and cannot adapt to the thickness change between the front teeth and the molars, which makes it inconvenient to use and cannot adapt to most people. The change of its position due to the change of the thickness of the molars is not conducive to cleanin...
