the motor 1 rotates to drive the valve core 5 to move so as to open an air flow channel to form an air supply state, the valve core 5 is driven by the rotating shaft 2 to move relatively in cooperation with a slope cavity in the valve seat 6, the electromagnetic valve 7 is jacked by the ejector rod 4, and a fuel gas channel is opened, so that normal air outlet ignition is realized; the thermoelectric couple generates thermoelectric force to supply power to the electromagnetic valve, and the electromagnetic valve 7 is opened to work;
when the combustion is suddenly interrupted, the thermoelectric voltage of the thermocouple is reduced and changed to stop the electromagnetic valve 7 from supplying power; the valve cavity is closed by quick reset under the action of elastic force, and the gas supply is blocked.
The valve seat 6 is integrally formed and comprises an air inlet cavity 61, a valve core cavity 62 and an air outlet cavity 63, wherein a passage port 64 is formed between the air inlet cavity 61 and the valve core cavity 62; the valve seat 6 provides a mounting cavity 65 for the solenoid valve 7, and a top end 71 of the solenoid valve 7 cooperates with the passage opening 64 to open or close.

In view of the foregoing, and in combination with the accompanying drawings, the following principles are provided:
under the normal air supply combustion state, the ejector rod is driven to open or close the power supply channel in a motor driving mode, high temperature is generated by flame, then the high temperature is obtained by the induction needle, electromotive force is generated and transmitted to the electromagnetic valve, the electromagnetic valve generates magnetic force to adsorb the iron sheet to drive the sealing ring for blocking the internal circulation channel of the fuel gas, and the function of opening the fuel gas valve channel is completed. The working principle of the electromagnetic self-priming valve is as follows: the position of the sensing needle is a first point, the electromagnetic valve of the valve seat is a second point, and when the sensing needle is connected with the electromagnetic valve of the valve seat, the temperature difference between the first point and the second point is the same under the condition that the stove is not ignited for use. When the temperature of the induction needle (the first point) rises and has a temperature difference compared with the second point after the stove burner catches fire, a certain electromotive force is generated between the two points, so that a current which can drive the electromagnetic valve coil to generate magnetic force is formed in the loop to supply power for the electromagnetic valve.
When abnormal combustion suddenly goes out, the temperature difference between the first point and the second point is lost, the electromotive force is lost, the electromagnetic valve is reset by the elastic force (spring) to block the outflow of fuel gas, and thus the automatic gas-break protection effect of flameout of the kitchen range is realized; automatic safety guarantee can be realized under normal state and abnormal state; therefore, it has excellent performance in technical, practical and economical aspects.
