In the early years, every household had to prepare matches because gas stoves needed matches to light. Now the gas stove can ignite automatically, which is much more convenient.
When you press and rotate the knob on the gas stove, you will hear the sound of "Da, Da, Da", and the gas will be lit at once, emitting a blue flame. However, the ignition principle of the gas stove is different from that of the lighter. It is the electric spark generated by the pulse igniter that ignites the gas. The pulse igniter uses the dry battery as the power supply, increases the voltage through the pulse high-frequency oscillator, discharges at the tip, and then sends out an electric spark.
Some gas stoves are also equipped with piezoelectric ceramic igniters. The so-called piezoelectric ceramics are ceramic materials with lead cobalt titanate as raw materials. When you press the ignition button with your hand, the piezoelectric ceramics are pressed by external force, which converts mechanical energy into electrical energy to form high voltage, discharge instantly, release electric sparks and ignite gas.
The advantage of pulse igniter is that the ignition success rate can reach 100%. The piezoelectric ceramic igniter is not easy to light gas when the humidity is high. Its advantage is that it does not need to install dry batteries, and has a long service life, which can be used more than 1 million times.
