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, which has set off a revolution in the field of oral health care abroad. The electric toothbrush generates high-frequency vibration through the rapid rotation or vibration of the motor core, which instantly decomposes the toothpaste into fine foam and deeply cleans the gap between the teeth. Massage effect.

In principle, there are two categories of electric toothbrushes: rotation and vibration. The principle of the rotary toothbrush is simple, that is, the motor drives the circular brush head to rotate, which enhances the friction effect while performing the ordinary brushing action. Large wear and tear, long-term use is not recommended. The vibrating type of toothbrush is more complex and more expensive in terms of price. There is an electrically driven vibration motor inside the vibration type toothbrush, which can make the brush head generate 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 largest swing in the industry is 6 mm. When brushing teeth, on the one hand, the high-frequency oscillating brush head can efficiently complete the action of brushing 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, which are generated when the bubbles burst. Pressure can penetrate deep between the teeth to clean the dirt.

However, some users like the effect of vibrating the toothbrush, and some users like the effect of rotating the toothbrush. Therefore, there is an urgent need for a multifunctional electric toothbrush with vibration and rotation functions.
