INSTRUCTIONS (1) [Technical Fields of the Invention] The present invention relates to a gas burner detecting device for air burning, especially a gas burner head having a central flame ring, having a telescopic temperature The sensor, and the cooking device air-burning detecting device with an anti-burning sheath on the periphery of the temperature sensor. [Prior Art] As is known, the misuse of many gas stoves often leads to serious consequences for life safety. For example, it is common for some cooks to cause long fires in the pot due to temporary negligence. The water is dried to form an air-burning state, and the high temperature of the air burning causes the cooking to burn, and even the ignition fire is harmful to public safety. In order to prevent the harm caused by the burning of cooking utensils, many gas stoves with "anti-air burning device" have been proposed. For example, the use of "Patent No. 8 7 2 1 5 6 7 9" The gas-fired prevention device of the gas furnace, and the "cooking water control method of the gas furnace" of the Chinese Patent No. 90 1 2 0 0 0 0, and the structure of the air-burning prevention device is slightly different from that of the gas-fired device. A temperature detector is arranged on the cooking pot and operated with a gas control mechanism to detect the temperature change parameter to control the opening and closing of the gas valve to prevent the hazard caused by the gas fire. According to the foregoing description, the accuracy of the temperature detection of the cooking device is directly related to the overall operation of the air-burning device, so in order to obtain the best temperature detection accuracy, the current general practice is The temperature detector is placed as close as possible to the fire and is connected to the bottom surface of the cooking utensil. For example, the temperature detector is placed at the center of the gas burner, but in order to prevent the temperature detector from being subjected to the burner The flame burns directly, causing detection

The result of the invention (2) is distorted, so the gas burners usually used with the temperature detector are designed without a central furnace ring, that is, in the central part of the burner (the temperature detector is installed) There should be no heating flame near the location. However, this type of burner without a central furnace ring can be used for regulation and control because there is no small fire (mother fire) in the central part, which is not only different from the current general habits, but also causes extreme inconvenience in cooking. In addition, most of the temperature detectors for preventing the air-burning device are fixed at specific positions. However, there are a wide variety of cooking pots commonly used at present, and the shape of the bottom of the pot is quite different, and the bottom of the pot is placed on the hob to form a pot bottom. The result is that when some pots are used, the temperature detector is not attached to the bottom of the pot, causing distortion of the detection result, and the overall prevention of the air-burning device cannot be effective. SUMMARY OF THE INVENTION The present invention provides a gas burner detection device that can be used with a gas burner having a central flame ring to allow a cook to regulate the use of a small fire in the center of the burner. The utility model has a temperature sensor capable of up-and-down telescopic displacement, so that the temperature sensor can be contacted on the bottom surface of the cooking pot to obtain accurate detection, and the anti-burning protection is provided on the periphery of the temperature sensor. Set to block the interference of external heat. According to the present invention, the detecting device is disposed at a central portion of the gas burner for detecting the burning of the cooking pot, and mainly comprises: a gas burner having at least one outer flame ring and a central flame a ring, a plurality of gas flame holes are opened outside the top ring edge of each flame ring, and a hollow portion is arranged in the center of the flame ring at the center of the burner; a sheath having an upper and lower mouth of a shape of 11 and 8 Square shaft hole, and
