Gas flows from the intake channel into the regulating valve, then from the regulating valve into the gas valve, and finally through the gas valve into the inner or outer ring gas supply channel. In normal operation, the valve core closes the valve port, and the intake channel and the gas valve are connected through a flow-limiting orifice. The gas flow into the gas valve is relatively small, resulting in a smaller gas flow into the inner or outer ring gas supply channel, suitable for normal cooking. In high-heat cooking mode, the valve core opens the valve port, resulting in a larger gas flow into the gas valve, and consequently a larger gas flow into the inner or outer ring gas supply channel, thus achieving the high-heat cooking function. Both normal and high-heat modes share a single gas path, eliminating the need for a separate high-heat path. Modifications can be made to the existing gas path, making the modification easier and less costly. Attached Figure Description

[0059] The reset member 250 is a spring 251, the spring 251 is sleeved on the outer circumferential side of the connecting rod 230, and gas can flow through the gap of the spring 251, so that the structure in the regulating valve 200 can be more compact, and the overall volume of the regulating valve 200 is reduced. The spring 251 is respectively abutted with the valve core 220 and the fixed seat 240 at both ends in the moving direction of the valve core 220, and since the position of the fixed seat 240 is fixed, the spring 251 can provide a force away from the fixed seat 240 to the valve core 220, so that the valve core 220 moves towards the valve port 211, and then the valve core 220 closes the valve port 211.
