Claims

[Claims for Utility Model Registration] (1) A dry battery 1 is used as a power source, and when a fire is extinguished, a capacitor 2 is charged with the battery voltage, and when a fire is ignited, the capacitor 2 is charged with the instantaneous adsorption side coil 6 of the safety valve Isv and the reed relay 4 as loads. In the instant adsorption type ignition device for gas appliances, the safety valve Isv is opened by discharging, and the reed relay contact 5 is turned ON, and the voltage of the dry cell battery serving as the power source is supplied to the igniter to generate a spark and ignite the reed relay. After the reed relay contact 5 of 4,
A battery voltage detection means 11 which enters a detection state when the reed relay contact 5 is turned on is provided, and a switch 12 operated by the output from the battery voltage detection means 11 is provided.
is connected to the instantaneous suction side coil 6 of the safety valve Isv,
The switch 12 is configured to block the current flowing to the instantaneous adsorption side coil 6 of the safety valve Isv based on the output from the battery voltage detection means 11 when the battery voltage falls below the set voltage, and furthermore, the set voltage is set to a practical voltage. Instant adsorption type ignition device for gas appliances. (2) After the instantaneous suction time when the safety valve Isv is forcibly opened at the time of ignition, the capacitor 2 supplies a current below the withdrawal current value to the instantaneous suction side coil 6 of the safety valve Isv via the current limiting resistor. An instant adsorption type ignition device for gas appliances as claimed in claim 1 of the registered utility model.
