Shock-absorbing electric toothbrush

Abstract

The invention provides a shock-absorbing electric toothbrush. The shock-absorbing electric toothbrush comprises a shell; the shell is provided with a motor bracket, a motor shock-absorbing seat, a motor and a shock-absorbing mechanism; the tail end of the motor is connected with the motor bracket by the motor shock-absorbing seat; the motor is sleeved by a motor shock-absorbing casing; the motor shock-absorbing casing is provided with a first through hole; one end of the shell is provided with a second through hole; the motor shaft of the motor successively passes through the first through hole and the second through hole; and the shock-absorbing mechanism abuts against the inner wall of the shell and is connected with the motor shaft. With such a technical scheme, collision among the motor, the motor bracket and the shell of the shock-absorbing electric toothbrush is reduced, the noise of the motor is decreased, and the motor is prevented from loosening and damage due to long-term vibration; the shock-absorbing mechanism is connected with the motor shaft and abuts against the inner wall of the shell, so vibration between the motor shaft and the shell is reduced, and noise generated during forward and backward rapid rotation of the motor shaft is further reduced, and thus, noise generated during working of the electric toothbrush is reduced.

Description

technical field [0001] The invention relates to the technical field of toothbrushes, in particular to a shock-absorbing electric toothbrush. Background technique [0002] Toothbrush is the most commonly used tool for cleaning teeth. It is used to remove bacteria, tartar and small debris attached to the teeth. It can prevent periodontal diseases and protect people's oral hygiene and dental health. The types of toothbrushes on the market There are many, and electric toothbrush is one of them. The electric toothbrush controls the positive and negative polarity of the motor through the circuit control board through the single-chip commutation, thus driving the motor shaft of the motor to achieve fast rotation in the forward and reverse directions, thereby driving the toothbrush head to achieve tooth cleaning. . And in the prior art, because the motor can produce bigger vibration when running, and the installation structure setting of the motor is unreasonable, the vibration tha...

Problems solved by technology

And in the prior art, because the motor can produce bigger vibration when running, and the installation structure setting of the motor is unreasonable, the vibration that produces during work is very big, and the vibration of the motor collides with the casing and the circuit control board. In addition, the motor shaft is in the There will also be collisions with the shell during fast forward and reverse rotation, which will generate a lot of noise, which will affect the user's experience, and it will also easily cause the motor to loosen and be damaged, thereby reducing its service life
