The discharge end made up from needle-shaped material adopts open type.In this way it can reach the goal of increasing the density of negative oxygen ion and reducing the density of ozone.When the atmosphere is normal inside,the potential of the gas sensor Q1's pin④ and pin⑥ is low.VT1 is stopped.The potential of IC3's pin② is high.The oscillator stops working.There's no negative oxygen generated.Rt is negative temperature coefficient thermistor.It compensates the errors causing by gas sensor Q1 as the temperature changes.The potential RP is used to adjust the sensitivity of detecting harmful gas.
