Technical Field

The technical scheme relates to a temperature measuring technology of a cooking pot used on a gas stove.

Background

At present, the structure of a temperature measuring probe of a cooking pot used on a gas stove is that a temperature sensing element is placed at the top end inside a stainless steel pipe. The periphery of the stainless steel pipe with the built-in temperature sensing element is additionally provided with a stainless steel pipe, and an air channel is formed between 2 steel pipes. The top of the outer layer steel pipe is lower than the top of the inner temperature sensing element steel pipe. The whole probe of the pan temperature sensor is propped against the center of the pan bottom through a spring. Firstly, the top of a stainless steel pipe internally provided with a temperature sensing element is exposed in the range of heat radiation of a gas stove, so that the temperature sensing element is greatly influenced by environmental heat radiation; secondly, the air flow heat dissipation layer is less; therefore, the temperature of the pot bottom cannot be accurately measured. Some pot temperature sensors have no air flow heat dissipation layer, and can not accurately measure the pot temperature.
