Electric massager is a kind of health care appliance that converts electric energy into mechanical vibration, using electric massager without the help of outsiders, you can massage by itself, convenient and labor-saving, the effect is better. According to the different structures, it can be divided into electromagnetic massage device and motor massage device, health care and beauty massage device, sports massage device and health care massage device, back massage device, face massage device, hand and foot massage device and general massage device, etc.
The structure of electromagnetic massager is mainly composed of shell, switch, spring sheet, movable core, fixed core, coil and massage head.movable iron core, fixed iron core and coil are called electromagnet, fixed iron core set with rubber pad, its role is to prevent movable iron core and fixed iron core direct collision, in order to reduce noise. The appropriate distance between movable and fixed cores is about 3~5mm, and the elasticity of the spring sheet should be moderate.
Electromagnetic massager working principle: connect the power supply, the coil will be sinusoidal ac, in ac positive, negative half weeks, electromagnet iron are attracted by magnetic, moving iron drive massage head move, every alternating current positive, negative half weeks switch moment, magnetic disappear to zero, massage head under the action of the spring sheet elastic recovery, so in ac a cycle, massage head will produce twice a shot of vibration. Under the power frequency (50Hz) alternating current, the vibration frequency of the massager is 100 times / second, namely 6,000 times / minute.
