The purpose of flameout protector:
When we use the cook top, the fire may be extinct because of the wind or overflowing water. In this case, the protector may cut off gas to prevent some accidents happening because of its leakage, such as poisoning, explosion or fire. In this way, it realizes its safety protection function.

The first step: Piezoelectricity
The second step: Valve-open condition
The top of the thermocouple is heated by fire, and it causes thermo electromotive force. Then it will be in series between the closed circuit and the valve. Outside force and the magnetic field breathe the valve and keep it open, and the gas channel is open.
The third step: Cut off gas in sudden flameout conditionWhen the fire is extinct because of wind or overflowing water, the thermo electromotive potential will minish quickly, and the ferrite core will come back to its original place to cut off the gas because of the loss of the spring effect.
