Electric toothbrush eccentric rod sound wave machine and working method thereof

Abstract

The invention provides an electric toothbrush eccentric rod sound wave machine and a working method thereof. An eccentric rod sound wave machine body is arranged in a machine body; the eccentric rod sound wave machine body comprises a group of involution type shells; a micromotor is arranged at one ends, away from a toothbrush handle, of the involution type shells, a motor shaft is arranged at theoutput end of the micromotor and points to the toothbrush handle, and the motor shaft is connected with one end of a positioning connecting shaft rod through an eccentric bearing seat; a positioningconnecting shaft seat is arranged at the other end of the positioning connecting shaft rod, and a positioning connecting shaft seat soft rubber sleeve is arranged on the outer ring of the positioningconnecting shaft seat; a concentric bearing seat, a bearing B and a metal shaft are sequentially arranged in the concentric bearing seat soft rubber sleeve from outside to inside; one end, away from the toothbrush handle, of the metal shaft is connected with the positioning connecting shaft rod; and the other end of the metal shaft is arranged in the toothbrush handle. The electric toothbrush eccentric rod sound wave machine can achieve the effect of an electric toothbrush adopting a magnetic suspension motor, and overcomes the defects that the brush head handle of an original resonance electric toothbrush is thick and large, the vibration swing amplitude is small, the brush head handle is prone to touching teeth and the tooth brushing force is not in place.

Description

technical field [0001] The invention belongs to the technical field of electric toothbrushes, in particular to an electric toothbrush deflection bar sonic machine and a working method thereof. Background technique [0002] The resonance electric toothbrush structure of prior art is as Figure 1 ~ Figure 2 As shown: there are mainly micro-motor 2, motor base 3, eccentric hammer connecting rod shaft 4, eccentric hammer with equal diameter 5, and eccentric hammer swing shaft 6; The connecting rod shaft 4 drives the equal-diameter eccentric hammer 5 to start high-speed rotation, drives the eccentric hammer swing shaft 6 to swing 360 degrees, drives the toothbrush handle 7 to swing and vibrate, and then transmits to the brush head 8 to achieve the effect of electric brushing. There are the following technical defects in use: 1), when the micro-motor 2 rotates, it is transmitted to the equal-diameter eccentric hammer 5 through the eccentric hammer connecting rod shaft 4, because i...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an electric toothbrush deflection bar sonic machine and its working method, which are used to solve the problem of the thick handle of the resonant electric toothbrush head in the prior art, the small vibration and swing range, and the The head handle is easy to touch the teeth, knock the teeth, vibrate and numb the teeth, and the brushing force is not in place.
