Abstract

An electric toothbrush with a moving and vibratory elastic body is formed by connecting a movable brush bristle base 2 and a bent brush neck outer casing 5 through the elastic body 1. One end of a built-in soft shaft 3 is connected with an output shaft 7 or connected via an eccentric wheel, and the other end of the built-in soft shaft 3 extends into a hole of the base 2 or is connected with the base 2. When a power source 10 is switched on, a motor 6 is controlled by a forward-backward rotation device 8, the output shaft 7 drives the soft shaft 3 or the eccentric wheel to reciprocate and rotate, simultaneously, the soft shaft 3 rotationally colliding the inner wall of a brush neck 5 enables rotary force of the soft shaft 3 to be changed to perform straight reciprocating movement or vibrate along the radial direction of the brush neck, or the eccentric wheel is driven to rotate to enable vibration generated by an outer casing of the motor 6 to be transmitted onto the base 2 through the soft shaft 3, and brush bristles 11 on the base 2 vibrate and move in three-dimensional omnidirection.

Description

The electric toothbrush of elastomer motion, vibration

Technical field:

The present invention relates to a kind of electric toothbrush, its movable part and stationary part are separated by by softish elastomer, motion or vibration are produced most power be delivered to bristle on the pedestal by driving shaft.

Background technology:

Various in the market electric toothbrushes are divided into motor type or oscillating mode from the bristle model of action, and its bristle can only be done plane motion and small vibration, and the motion of bristle and vibration all are inflexiblely to contact with facing and can not go deep into tooth ditch nest and difficult brush portion position; Promptly damage gingiva and be not suitable for child's use also inconvenience and operation again.

Summary of the invention:

This utility model purpose is to overcome the deficiencies in the prior art, provide the bristle of motion that a kind of bristle not only can do softish three-dimensional all-directional or vibration can go deep into any position of tooth. the bristle pedestal links to each other with the brush neck of bending by elastomer, one of built-in driving shaft stretches in the hole of bristle pedestal or directly links to each other with the bristle pedestal, the other end links to each other with output shaft or is meshed with eccentric, the vibration force of its motion or vibration and driving mechanism is produced the power of resonance, be delivered to make on the pedestal by driving shaft and connect vibration or the motion that bristle is done three-dimensional all-directional with pedestal.The excessive brush of elastic force absorption of elastomer and elasticity brush neck is tried hard to keep and has been protected gingiva, and crooked brush neck is convenient to operation.
