[0002] Two kinds of spray guns exist in the market at present, and the main difference between the two kinds of spray guns has two points:

[0003] 1. The number of turns of the coil is different, and the number of turns is different because the spray gun has different spray force requirements, and the number of turns of the coil with a diode is more, and the number of turns of the coil without a diode is less;

[0004] 2. Whether a diode exists, the diode is used for controlling the direction of alternating current of the coil, so that the current in the coil can only flow in one direction, thereby reducing the frequency of the magnetic force generated by the coil and the silicon steel sheet by half.

[0005] The spray gun without a diode has a faster internal running frequency, so that the liquid sprayed by the spray gun is relatively small but rapid, and finally exhibits relatively soft cleaning force, and the spray gun is not easy to damage the cloth and is suitable for cleaning relatively thin cloth;

[0006] The spray gun with a diode has a slower internal running frequency, so that the liquid sprayed by the spray gun is relatively more but has a low frequency, and finally exhibits relatively strong cleaning force, and the spray gun can quickly clean the cloth and is suitable for quickly cleaning heavy cloth.
