What is the principle of Ceramic Pellet Igniter?

Piezoceramics are devices that convert mechanical force into electrical sparks to spark combustion. It uses the piezoelectric ceramic element under the action of mechanical force elastic deformation and high pressure output, and then through the high pressure spark discharge, flammable gas. Cylindrical piezoelectric ceramic elements for ignition.

History Pellet Igniter principle: Turn the CAM switch 1 to push the impulse block 3 with the force of the CAM bulge part. And compression of the spring after the impact block 2. When the CAM to a certain position, the CAM protrudes from the impact block, under the action of the spring force, the impact block to the piezoelectric ceramic element 4 an impact force. High voltage is generated at both ends of the piezoelectric ceramic element, which is led out from the middle electrode 3, and an electric spark is formed at the gap of the piezoelectric igniter to ignite the gas.
