Patent ID: 7601970

Claim:
An Alternating Current (AC) negative ion and silver ion generator, comprising: an AC power supply unit for supplying an AC voltage required to operate the ion generator; an oscillation unit including first and second resistors, first and second diodes and a first condenser, the oscillation unit oscillating and generating an output pulse having a certain frequency when the voltage is supplied by the AC power supply unit; a switching unit including third and fourth resistors and a Silicon Controlled Rectifier (SCR) to perform a switching operation in response to an output frequency of the oscillation unit; a boosting unit for boosting an AC voltage having a certain frequency, output through the switching unit, to a high AC voltage required to generate negative ions; and an output unit including a fifth resistor, a third diode and a second condenser to output the high voltage supplied by the boosting unit to a negative ion generation unit, wherein the negative ion generation unit is driven by the high voltage output from the output unit, and nano-sized silver ions are coated on a metallic fiber placed at an end of a discharge electrode such that the negative ion generation unit simultaneously emits negative ions and silver ions from the metallic fiber when the negative ion generation unit is driven by the high voltage output from the output unit.
