Description
Technical Field
The invention relates to a rotary automatic speed regulation electric toothbrush for protecting gum, and mainly relates to the technical field of toothbrushes.
Background
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 common tooth brushing action is carried out, the rotary toothbrush has high strength, the tooth surface is cleaned completely, but the rotary toothbrush has high abrasion to the teeth, 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, more than thirty thousand times of vibration per minute also enables the mixture of toothpaste and water in the oral cavity to generate a large amount of tiny bubbles, and the pressure generated when the bubbles burst can deeply penetrate into the gaps between the teeth to clean dirt.
However, when the rotary electric toothbrush is used, the phenomenon that the gum bleeding is easily caused by the fact that a user presses the brush which rotates at a high speed due to the fact that the user presses the brush too heavily occurs to individual users, the swinging angle of the brush on the electric toothbrush in the market is fixed, and the electric toothbrush cannot adapt to the situation that the user presses the brush with different force to make adaptive adjustment, so that the oral cavity of the user is damaged, and therefore the rotary electric toothbrush is designed to solve the problems.
