The working principle of electric toothbrush:
1. The working principle of electric toothbrush is that the circular brush head is driven by the motor to rotate, which strengthens the friction effect while performing ordinary brushing action. The rotating toothbrush is noisy, the tooth surface is cleaned very clean, and the interdental cleaning is relatively weak, but it is not recommended to use for a long time. Vibrating toothbrushes are more sophisticated and, in terms of price, more high-end.
2, ultrasonic toothbrush is the use of ultrasonic energy in the periodontal cavitation effect to remove periodontal bacteria and unclean things, its cleaning range can cover all parts of the periodontal. Ultrasonic energy is transmitted to the teeth and gingival surface through the bristles of the brush head. On the one hand, it loosens the adhesion of plaque, tartar and small calculus to the teeth, and destroys the parasitic propagation of bacteria in the gingival pocket and the hidden places on the tooth surface.
3. At the same time, ultrasonic energy transmitted to the gingival surface by touching the bristles further penetrates into the gingival interior, acts on the cell membrane, accelerates blood circulation and promotes metabolism.
Features of electric toothbrush:
1. A wide range of frequencies
The operating frequency range of the same acoustic motor with brush head can be adjusted from 100Hz to 350Hz at rated voltage and duty cycle. Considering the user experience, the recommended operating frequency range is usually 250Hz to 290Hz, with slight differences between different series.
2. Strong load capacity
The acoustic motor not only has a brush head used to achieve a specific swing, but also has a certain swing under load. Due to the characteristics of the acoustic motor itself, the output torque in the reciprocating swing cycle is variable, and different brush heads have different swing amplitude.
3. Good consistency and high stability
Acoustic wave electric toothbrush motor is designed for no shrapnel structure, and there is no difference in the shape of the heat treatment of the shrapnel hardness, caused by the consistency of product performance problem; With MAGNETIC SPRINGS, there is no FATIGUE aging problem DURING the life of the mechanical spring/shrapnel, and there is no swing fluctuation caused by fatigue of the mechanical spring or shrapnel.
