A sexual gas passage 11 is connected. Both gas passages 9
．． 11, a solenoid valve 12 constituting an automatic gas supply control device;
13. A sequencer 14 is provided, and this solenoid valve 12.
13 is opened and closed by a sequencer 14. This sequencer 14 simultaneously controls both electromagnetic valves 12 and 13 when the detection signal from the infrared detector 5 described above stops for a certain period of time, for example, a period slightly longer than the time required from the gas supply operation to the completion of the ignition operation during normal ignition. It is operated to close the flow path.

が停止される。This hand burner opens both electromagnetic valves 12.13 while operating the sequencer 14, sends gas from both gas passages 9.11 to the nozzle 4, and when ignited within a certain period of time, emits infrared rays from the flame at the tip of the nozzle. The infrared detector 5 senses this, thereby keeping both solenoid valves 12, 13 open. On the other hand, if the infrared detector 5 does not detect infrared rays within a certain period of time without being ignited, the sequencer 14 closes the solenoid valves 12 and 13, and the outflow of gas from both gas passages 9 and 11 is stopped.

尚、赤外線検出器５の向きはポルト７をゆるめることに
より調節でき、炎の大きさに対応できるようにしである
。Incidentally, the direction of the infrared detector 5 can be adjusted by loosening the port 7, so that it can correspond to the size of the flame.
