When the valve stem 200 drives the valve core to rotate so that the temperature control gas groove 330 and the air inlet 120 are connected, the gas will pass through the air inlet 120, the temperature control gas groove 330 and the valve cavity 150 in sequence, and finally flow out from the second outlet 140.

By switching the gas channel by the main valve core 300, the gas can flow out from different channels, and the gas flow can be selected as a high-fire direct pass or intelligent temperature-controlled ventilation. Therefore, the temperature control conversion valve of the embodiment of the present invention can simply and directly switch the advantages of the valve used by the stove, so that the stove can directly meet various different usage requirements. By using the temperature control conversion valve, the same stove can directly switch different functions, such as switching from a direct-fire grilling function to an automatic temperature control function, so that users can use the stove more conveniently without having to replace the valve, thereby greatly improving the market competitiveness of the stove using the temperature control conversion valve.
