The negative ion of the simple negative ion generator increases, which has hypnosis, antiperspirant, analgesia and appetite for people, which makes people refreshed and relieves fatigue. The figure is a circuit diagram of the negative ion generator. 220V AC mains is recharged to C3 and C2 after being rectified by D1. When C2 is charged until the bubble is turned on and SCR is turned on, C3 is discharged through L1 of SCR and B, and after being boosted by B, it is reverse rectified by D2. A high voltage of 8 kV is used to ionize the molecules of the generator M to generate negative ions. Adjusting the resistance of R3 can change the trigger frequency and output voltage. Safety must be observed when adjusting, and the power plug must be disconnected when replacing components.
