Technical Field
The utility model relates to a temperature control device of a gas stove, in particular to an anti-dry heating probe for the gas stove.
Background
An anti-dry heating probe of a gas stove generally comprises a probe head shell, a temperature sensing controller, a spring and a fixed rod. A temperature sensing controller is arranged in the shell of the probe head, and a spring for controlling the head of the probe to lift is arranged below the temperature sensing controller. When in use, the head of the probe moves up and down relative to the fixed rod. The temperature induction controller adopts a thermistor for temperature control, a kick type temperature controller for temperature control and an NTC (negative temperature coefficient) heat-sensitive sensor for temperature control. In the existing anti-dry heating probe, a section of spring is generally arranged in the head of the probe, and the spring is also completely arranged in the head of the probe. When in use, the service life of the spring is adversely affected due to the higher temperature of the probe head.
In order to effectively contact the top of the dry-heating-preventing probe with the bottom of the pot and better detect the temperature of the bottom of the pot, the dry-heating-preventing probe adopting the thermistor temperature control is adopted in the market, a larger gap is reserved between the head of the dry-heating-preventing probe and a fixed rod along the radial direction at the matching part, so that when the bottom of the pot is locally uneven or inclined, the top of the dry-heating-preventing probe can be automatically adjusted correspondingly and is effectively contacted with the bottom of the pot. The head of the probe can be obviously felt to shake along the radial direction by hands, and the gas stove with the dry-burning-proof probe is easy to damage the dry-burning-proof probe if Chinese style cooking 'tossing pan' is adopted for cooking.
