2. ion flame sensing type flame-out protection device, its structure is that a self-priming magnetic valve is installed on the gas-cooker air inlet pipe, general No. 1 dry cell power supply of two joints that adopts of self-priming magnetic valve is equipped with the ion flame-sensing needle that is used to survey flame in each burner fire hole site.Its operation principle is: when the operator opens the plug valve igniting, self-priming magnetic valve self-priming circuit is connected and is opened automatically, the combustion gas gas circuit is connected, and this moment, the ion flame-sensing needle detected burner flame, and signal is passed to ignition controller, ignition controller control self-priming magnetic valve is held open state, when the flame accident was extinguished, the ion flame-sensing needle was surveyed less than burner flame, and signal is passed to ignition controller, ignition controller control self-priming closed electromagnetic valve, thus fuel gas path cut off.But; the defective of this flame-out protection device is: on the one hand; because structural limitations; the self-priming magnetic valve is installed on the air inlet pipe and can only installs one; self-priming magnetic valve and all burners polyphone; therefore when gas-cooker is provided with two or more burners, can't accomplish blowout protection one to one, promptly any one burner flame accident extinguishes that then all burners will be by Close All.On the other hand, because the self-priming magnetic valve is kept the required power supply of opening and all provided by battery, therefore the power consumption of this blowout protection structure is bigger, and the battery altering frequency is higher.
The utility model content
Technical problem to be solved in the utility model is, provide a kind of make stopcock structure simple, need not the blowout protection that prolongs the knob spinning time, can realize single burner and can save the gas combustion range flameout protector of battery.
For solving the problems of the technologies described above; a kind of gas combustion range flameout protector that the utility model provides; comprise plug valve; the self-priming magnetic valve; burner; thermocouple; microswitch; the igniting pin; controller; battery; described microswitch is contained on the plug valve and with the controller lead and is connected; described igniting pin is connected with the controller lead; described thermocouple head is connected on the burner; its head is positioned at burner fire hole next door; described controller is connected with battery lead. and described self-priming magnetic valve is at plug valve and be connected between the gas-distributing pipe on the burner; described self-priming magnetic valve is connected with thermocouple wire, and is connected with the controller lead.
After adopting above structure, owing to adorned the self-priming magnetic valve between plug valve and burner gas-distributing pipe, stopcock structure is just simple, need not to install post rod mechanism.Magnetic valve is to utilize powered battery when opening, and then need not to prolong the spinning time of knob.Be to utilize thermoelectricly to meet the electromotive force power supply that flame heat energy produced by chance and be held open state after magnetic valve is opened, therefore need not powered battery, thereby can save battery.Moreover the self-priming magnetic valve is to be contained on the gas-distributing pipe of each burner of gas-cooker, can realize separately protected behind the burner accident extinguishing.
