The principle of mini massager
Electromagnetic massagemachine is mainly composed of electromagnetic core and coil, when the coil is connected to 50Hz power frequency alternating magnetic field, it produces alternating magnetic field, the alternating magnetic field is small and then large, drives the iron core to produce vibration, and then passes the vibration to the massage head, because our country uses 50Hz alternating current, so the vibration frequency of the massage head is 100Hz.
The vibration source of the electric massager is the motor. Generally speaking, the motor of the massager is the permanent magnet miniature DC motor. The working principle of the electric massager is: the rotation of the motor spindle is transmitted to the eccentric wheel through the coupling spring. The role of the eccentric wheel is to convert the rotating motion of the motor into reciprocating motion, and the reciprocating motion is transmitted to the vibration head. Because the motor speed is 5000~10000 RPM, the vibration number of the electric massager is also 5000~10000 times per minute.
How to use Mini massager
1. The newly bought massager should be disinfected first.
2, after cleaning the product, first connect the USB cable or open the top cover into the 3 No.7 batteries, check whether the product is normally energized. If it works, it's safe to use.
3. In the use of mini massager, it is necessary to pay attention to the difference in vibration intensity between the massage parts of the body. For example, when massaging the head, face and other vulnerable parts of the human body, we should choose the weak gear, and the other parts can choose the strong gear, the use of strong vibration, the feeling is more comfortable, the effect is better.
