Description

Electric toothbrush head

Technical Field

The utility model relates to an electric toothbrush head technical field especially relates to an electric toothbrush head.

Background

The electric toothbrush is a toothbrush invented by Philippe-Guy Woog, the brush head generates high-frequency vibration through the quick rotation or vibration of a motor core, toothpaste is instantly decomposed into fine foam to deeply clean slits between teeth, meanwhile, the vibration of bristles can promote the blood circulation of an oral cavity, and the electric toothbrush has a massage effect on gum tissues, has already opened a revolution in the field of oral health care abroad, and has two major types from the principle: 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 driving vibrating motor is arranged in the vibrating toothbrush, so that the brush head can generate high-frequency swing perpendicular to the brush handle direction, but the swing amplitude is very small, generally about 5 mm for each of the upper part and the lower part, and the maximum swing 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.
