The working principle of hair dryer negative ion

Negative ion generator is a device that generates negative ions in the air. After the input DC or AC power is processed by the EMI processing circuit and the lightning protection circuit, the pulse circuit is used to limit the overvoltage and current; the high and low voltage isolation lines are upgraded to AC high voltage , And then rectify and filter through special grade electronic materials to obtain pure DC negative high voltage, connect the DC negative high voltage to the release tip made of metal or carbon element, use the cutting-edge DC high voltage to generate high corona, and release a large number of electrons at a high speed (e- ), and electrons cannot exist in the air for a long time (the lifetime of the existing electrons is only nS level), and will be immediately captured by the oxygen molecules (O2) in the air to generate negative air ions. It is reported that there are more advanced negative ion release tips: nanofullerene negative ion release tips, which can generate pure negative ions.

Air negative ions can be divided into light, medium and heavy ions according to their volume. The diameter of light ions is about 0.000001cm, and they move faster in the electric field. It is 1～2 cm2/VS. In nature or ordinary environment, the mobility is greater than 0.4 cm2/(V.s), which are small particle size negative ions. The diameter of heavy negative ions is about 0.0001cm, and it moves slowly in the electric field, only 0.0005 cm2/VS. In nature or in ordinary environments, the size and activity of medium-sized anions are between light and heavy ions. Among them, the small particle size negative ions have good biological activity and are easy to penetrate the human blood-brain barrier and enter the human body to exert their biological effects. The traditional negative ion generation technology cannot generate small particle size negative ions. Only the use of negative ion converter technology and nanofullerene negative ion release technology can produce small particle size negative ions.
