Ignition mode: The ignition mode of the gas stove mainly includes electronic pulse ignition and piezoelectric ceramic ignition. Embedded furnaces use electronic pulse ignition mode. When it reaches a certain location, it will catch fire. It has a high ignition hit rate, generally 100%, but this way requires battery replacement. The benchtop furnace adopts piezoelectric ceramic ignition method, and the ignition success rate is greatly affected by the environmental humidity. When ignition is required, the switch needs to be pressed to ignite.





How to judge whether the ceramic ignition needle is normal?
The ignition needle is generally not easy to break. If the ignition pin is not discharging, there may be a dead battery or a faulty pulse igniter, which is not necessarily a problem with the ignition pin. If you replace the battery with a new one, it is recommended to find the factory after the sale. The ignition methods of gas ceramic ignition needles and ignition rods are mainly divided into piezoelectric ceramic ignition and electric pulse ignition. Modern gas stove igniters are mostly pulse igniters. Pulse igniters are pulsed high-frequency oscillators composed of electronic components. The high-frequency voltage generated by the oscillator is raised to a high voltage of 15KV through a step-up transformer. A discharge is performed, and the spark on the gas stove is ignited by the discharge spark. The igniter is fired for continuous discharge. When the knob is pressed, the pulse igniter starts firing; when the knob is released, the pulse stops firing.

How to determine whether the ceramic ignition needle is normal?
When the knob is pressed and a small fire ignites, the thermocouple is heated by its flame to generate a thermoelectric potential. The thermoelectric potential is introduced into the solenoid coil through the wire, and a magnetic field is generated to make the solenoid valve suck. Open the gas valve, open the combustion channel, and maintain normal combustion. When the ceramic ignition rod overflows with strong wind or soup, the flame goes out and the thermoelectric potential of the thermocouple is very high. It quickly drops to zero, the coil is de-energized, the solenoid valve fails, and it resets quickly under the action of the spring. The valve closes the gas passage and stops the gas supply for safety.
