When concentration, since the raising of gas sensor Q second end current potential makes triode VT saturation conduction, play the role of detection switch.
Thermistor RT is negative tempperature coefficient thermistor, for compensating gas sensor Q deviation due to caused by temperature change.With
TWH8751 switch chip IC is that the circuit of center device forms negative oxygen ion generator, and frequency of oscillation is about 1kHz, in transformation
The high pressure of 5kV or so can be obtained in T grade of device.Spray point A is substantially increased the concentration of negative oxygen ion, is reduced using open
The concentration of ozone increases the negative oxygen ion for reaching outside, and when the normal phase input end of switch chip IC is high potential, oscillator stops
Vibration, under normal ambient environments, resistance is very big between the both ends gas sensor Q, and the second terminal potential is very low, triode VT cut-off,
The normal phase input end of gas sensor Q is high potential, and oscillator does not work, and is generated without anion, when indoor toxic gas
Concentration has been more than the critical value of potentiometer RP setting, and triode VT saturation conduction, the normal phase input end of gas sensor Q is in low electricity
Position, oscillator starting of oscillation generate negative oxygen ion.Anion can eliminate indoor toxic gas to a certain extent, reach pure and fresh
