Description

Medical electric toothbrush

The patent application of the invention is divisional application. The patent number of the original case is 201710492619.2, the application date is 2017, 6 and 26, and the invention name is a medical electric toothbrush.

Technical Field

The present invention relates to a medical grade tooth cleaning product, and more particularly to a powered toothbrush with rotation and vibration capabilities.

Background

Electric toothbrushes are new products that have emerged in recent years, and have revolutionized the oral care field abroad. The electric toothbrush enables the brush head to generate high-frequency vibration through the rapid rotation or vibration of the electric motor core, instantaneously decomposes the toothpaste into fine foam, and deeply cleans teeth gaps; meanwhile, the vibration of the brush hair can promote the blood circulation of the oral cavity and has a massage effect on the gum tissue.

In principle, electric toothbrushes have two main categories: rotation and vibration. The principle of the rotary toothbrush is simple, namely the motor drives the circular brush head to rotate, the friction effect is enhanced while the ordinary tooth brushing action is carried out, the rotary toothbrush is high in noise, the tooth surface is cleaned cleanly, the tooth gaps are relatively weak to clean, the abrasion to teeth is large, and the rotary toothbrush is not recommended to be used for a long time. The vibration type toothbrush is more complicated and higher in price. The electric driven vibrating motor is arranged in the vibrating toothbrush, so that the brush head can generate high-frequency swinging perpendicular to the direction of the brush body, but the swinging amplitude is very small, generally about 5 mm for each of the upper part and the lower part, and the largest swinging amplitude in the industry is 6 mm. When the toothbrush is used for brushing teeth, on one hand, the brush head which swings at high frequency can efficiently finish the action of brushing teeth, on the other hand, the mixture of toothpaste and water in the oral cavity can generate a large amount of tiny bubbles by vibration for more than 30000 times per minute, and the pressure generated when the bubbles burst can deeply penetrate into gaps between teeth to clean dirt.

However, some users prefer the effect of vibrating the toothbrush, and some users prefer the effect of rotating the toothbrush, so that a multifunctional electric toothbrush with vibration and rotation functions is needed.
