The user can be according to self demand, according to the massage position regulation of difference, increases and uses the travelling comfort.

The electromagnetic massager has the following use process: the user of the product turns on the power switch 22 and holds the handle 2 with his hand, at which time the spring 63 is in a natural state. When the user aligns the massage head 5 with the body part and presses it with a little force, the spring 63 is stressed and contracted, when the blocking piece 62 at the rear end of the coil fixing sleeve 41 is inserted between the transmitting end and the receiving end of the photoelectric switch 61 to a certain extent, the travel switch 6 is triggered, the travel switch 6 sends a corresponding signal to the controller on the main control board 7, and after the controller receives the trigger signal, the coil 44 is electrified with short-time current. Because the coil 44 is hollow inside, according to the ampere rule (right-hand spiral rule) principle, a closed-loop magnetic field is produced inside and outside the coil 44, one end of the coil 44 is south pole, the other end is north pole, and the direction of the magnetic field is determined by the electrifying direction. As the magnet is arranged in the hollow cavity inside the coil 44, as long as the north and south poles of the magnet and the south and north poles of the magnetic field generated by the coil 44 are in the same direction, the whole moving mechanism 4 can drive the massage head 5 to move forwards under the action of the outward elastic force of the spring 63 according to the principle that like poles repel each other, thereby realizing the external knocking effect.

Because the power-on time of the controller to the coil 44 is short, and the user presses the massage head 5 on the body part all the time, the massage head 5 is pressed back quickly after being driven out, and is triggered to a certain degree to send a corresponding signal to the controller, and the controller starts to power on again, so that the continuous knocking is realized by the cyclic reciprocation. When the user wants to change the massage position or temporarily stop the massage, the massage head 5 is not pressed against the body, the spring 63 keeps the travel switch 6 in the separated state, and the massage gun stops operating immediately.

The electromagnetic massager is driven by electromagnetic force, and has compact structural design, small overall size and low noise. When the massager works, the coil 44 is electrified only at the moment when the massage head 5 is driven out, and the coil 44 is not electrified in the whole process, so that the electric energy is saved, and the endurance time is long. The striking strength depends on the size of the current of the coil 44, the striking strength can be increased by increasing the current of the large coil 44, the striking strength can be conveniently adjusted through the current adjusting knob, and the comfort is improved. The coil and the photoelectric switch are fixedly arranged, so that the power supply circuit is convenient to connect.
