The principle of the ion blower 72 is that when the charge on the surface of the circuit board 3 is negative charge, it will attract the positive charge in the air flow; when the charge on the surface of the circuit board 3 is positive charge, it will attract the negative charge in the air flow; when the equal amount of positive and negative charges come into contact, the electrical neutralization can be achieved.
