However, the method has accurate requirements on the installation positions of the infrared transmitting tube and the infrared receiving tube, otherwise, the judgment result is influenced; in addition, under the working environment of heavy oil and heavy water in a kitchen, the infrared transmitting tube is easily blocked and damaged by oil stains to lose effectiveness, so that the position of the pot cannot be accurately judged.

The other way is that a pot supporting bracket is arranged at the front part of the furnace body, a set of mechanical structure capable of controlling the opening and closing of the main gas fire valve is arranged below the bracket, and when the pot leaves the hearth and is placed on the pot supporting bracket, the weight of the pot body presses down the set of mechanical structure to close the main fire valve; when the pan leaves the pan supporting bracket, the main fire valve is opened under the action of elasticity, and the main fire resumes combustion. However, the mechanical structure of the pot set is complex to install, the main fire can be effectively extinguished only when the pot is placed on the pot supporting bracket, and when the pot is lifted for loading, the main fire is still combusted greatly, and only flameout of the pot in a local range is realized; in addition, when the device is used for a long time, the complex mechanical mechanism is easily stuck by oil smoke to influence the flameout effect.
