Description

A medical electric toothbrush

The patent application for the present invention is a divisional application. The patent number of the original case is 201710492619.2, the application date is June 26, 2017, and the name of the invention is a medical electric toothbrush.

technical field

The invention relates to a medical-grade tooth cleaning product, in particular to an electric toothbrush with rotation and vibration functions.

Background technique

Electric toothbrush is a new product that has appeared in recent years, and it has set off a revolution in the field of oral health care abroad. The electric toothbrush uses the rapid rotation or vibration of the motor core to generate high-frequency vibrations on the brush head, which instantly decomposes the toothpaste into fine foam and cleans the gaps between the teeth deeply; massage effect.

In principle, there are two types of electric toothbrushes: rotation and vibration. The principle of rotary toothbrushes is simple, that is, the electric motor drives the round brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. High wear and tear, not recommended for long-term use. Vibrating toothbrushes are more complex and higher-end in terms of price. There is an electric-driven vibration motor inside the vibration type toothbrush, which can make the brush head produce high-frequency swing perpendicular to the direction of the brush body, but the swing amplitude is very small, generally about 5 mm up and down, and the industry's largest swing is 6 mm. mm. When brushing your teeth, on the one hand, the high-frequency oscillating brush head can efficiently clean your teeth. On the other hand, the vibration of more than 30,000 times per minute also makes the mixture of toothpaste and water in the mouth produce a large number of tiny bubbles. The pressure can go deep between the teeth to clean the dirt.

Yet some users like the effect of vibrating toothbrush, and some users like the effect of rotating toothbrush, therefore, need badly a kind of multifunctional electric toothbrush with vibrating and rotating function at present.
