Piezo igniter

Piezoelectric igniter is a manual ignition device produced on the basis of piezoelectric effect and using piezoelectric ceramics as medium. It is mostly used in various gas appliances, such as gas stoves, gas water heaters, and gas refrigerators.

Compared with pulse ignition, piezoelectric ignition has shortcomings such as short discharge time, manual operation, and low ignition success rate, and is being phased out by pulse igniters.

Piezoelectric ignition is still the most important ignition technology in the field of gas appliances for a long period of time

The piezoelectric igniter in ordinary piezoelectric lighters can generate high-voltage pulses of up to 1000 volts; the voltage can be reduced to several or even lower through the use of rectifier bridges, capacitors and Max666 voltage regulators. The research also found that the resistance value of the connected load has a sharp impact on the output power of the piezoelectric igniter. When the resistance value is 0.22 kΩ, the output power reaches a maximum value of 0.26mW, which can basically meet the power consumption requirements of some small electronic equipment.
