Simple production of negative ion generator circuit diagram

The simple negative ion generator increases negative ions and has the effects of hypnosis, antiperspirant, analgesia, increase appetite, refreshing people and eliminating fatigue. The picture is the circuit diagram of the negative ion generator'>Circuit diagram. The 220V AC mains power is rectified by D1 and then charged to C3 and C2. When C2 is charged until the neon bulb is turned on and triggers the SCR to turn on, C3 is discharged by the SCR and L1 of B. After being inducted and boosted by B, it is reversely rectified by D2. The 8kV DC high voltage is obtained to ionize the molecules of the generator M to produce negative ions. Adjusting the resistance of R3 can change the trigger frequency and output voltage. Safety must be paid attention to when adjusting, and the power plug needs to be unplugged to replace components.
