A PORTABLE NEGATIVE ION GENERATOR AND A CONTROL CIRCUIT THEREOF

The present invention relates to a portable negative ion generator and a control circuit thereof. More particularly, the present invention relates to a portable negative ion generator which minimizes volume, generates enough negative ions at a low voltage, and maintains a pleasant environment, and a control circuit thereof. More particularly, the present invention includes a negative ion power inputting part which applies a voltage to a negative ion generator, a micom which changes a voltage applied to the negative ion power inputting part into a high voltage and controls the generation of negative ions, an inverse voltage preventing part which blocks an inverse voltage which backflows from the micom to the negative ion power inputting part, an oscillation part which oscillates a DC power with a constant frequency to change a voltage applied to the negative ion power inputting part into the micom, a power distribution part which distributes the high voltage of the micom to a negative output tip, and an output tip which outputs negative ions by distributed high voltage.
