4. for an electromagnet in the circuit, when the piezoelectric ceramic piece is used for charging the capacitor, the voltage is larger and the current is smaller, so that the current passing through the electromagnet is smaller, the magnetic force generated by the electromagnet is smaller, the magnetic repulsion force on the permanent magnet layer on the sliding block can be ignored, when the capacitor is in a breakdown state, the short-circuit current output by the capacitor to the electromagnet is larger, so that the electromagnet generates larger magnetic force, the magnetic repulsion force on the permanent magnet layer in a period of time when the capacitor is discharged is larger than the elastic force of the spring, the push rod pushes the baffle plate to seal the air inlet pipe, the air inlet pipe cannot output combustible gas to the gas channel, and the flame above the gas channel is automatically extinguished after losing the combustible medium, so that the effect of automatically cutting off the heating source is realized;

5. after the capacitor is discharged, the cooker on the support table gradually becomes not shaken, so that the piezoelectric ceramic piece does not generate the discontinuous charging effect on the capacitor, and the capacitor is a healing capacitor, so that the performance is recovered after being broken down and the capacitor can be continuously used;

6. set up the resistance box that can adjust simultaneously in the electronic box for adjust the electric current under the condenser puncture discharges, make the extreme position that the adjustment push rod removed, when heating hot water, can set up to the incomplete sealed intake pipe of baffle, but leave a less space, make and continue to carry out the soft fire heating, can realize that the big fire of hot water juice boils, the process of the soft fire system of stewing, promotes the intelligent result of use of gas-cooker.
