Vertical brushing type electric toothbrush

Abstract

The invention discloses a vertical brushing type electric toothbrush, which comprises a brush head and a transmission part, wherein the brush head comprises brush hair, a fixing part and a pulling part; the brush hair is arranged at one side of the fixing part; the pulling part is arranged at the other side of the fixing part; an open hole is formed in the pulling part; the transmission part comprises an electric motor, a transmission rod and a pulling rod; one end of the transmission rod is fixed on the electric motor; the other end of the transmission rod is fixed to the pulling rod; the free end of the pulling rod is positioned between two walls of the open hole; the electric motor drives the pulling rod to rotate through the transmission rod; the free end of the pulling rod alternately collides with the two walls of the open hole during rotation; and further, the brush hair is driven to do back and forth linear movement in the collision direction. The vertical brushing type electric toothbrush provided by the invention has the beneficial effects of high rotating speed, low friction, good heat-insulation performance and the like.

Description

technical field [0001] The invention relates to the field of electric toothbrushes, in particular to a vertical brush type electric toothbrush. Background technique [0002] Toothbrushes on the market mainly include manually operated toothbrushes and electric toothbrushes, among which, compared with manually operated toothbrushes, electric toothbrushes can clean teeth more thoroughly, remove dental plaque, reduce gingivitis and gum bleeding, and thus are favored by people .

Yet existing vertical brush type electric toothbrush often can't reach the purpose of correct teeth brushing due to its structure, and the hair bundle of these vertical brush type electric toothbrushes all is...

AI Technical Summary

Problems solved by technology

Yet existing vertical brush type electric toothbrush often can't reach the purpose of correct teeth brushing due to its structure, and the hair bundle of these vertical brush type electric toothbrushes all is to vibrate back and forth with the circular direction when vibrating, rather than with 90 degree normal Anti-motion, and the vibration torque of the toothbrush bristles is not large, a slight pressure may cause the vibration to stop, which cannot achieve the purpose of effectively cleaning the teeth and cannot meet the use requirements
