To discriminate an emergency extinguishment from an ordinary extingushment and achieve an extinguishing operation by providing a temporary engaging means formed of a solenoid operated by an output from a first delay means on the way of a track of the extinguishing base pin of a wick raising and lowering plate for setting a wick.
A solenoid 21a forming a temporary engaging means 21 urges a temporary urging lever 21b toward the solenoid 21a side under the urging force of a spring so that the rotation of an extinguishing base pin 13 is not interrupted. The temporary engaging lever 21b is projected on a track on which the extinguishing base pin 13 rotates only for a prescribed time upon extinguishment to temporarily stop the rotation of the extinguishing base pin 13 so halfway. Then, the amount of vaporization from a wick 3 is restricted to continue a combustion. After a prescribed time, the delay element of the first delay means 23 is released to turn off the solenoid 21a of the temporary engaging means 21. Accordingly, the temporary: engaging lever 21b returns to an original state and the wick 3 is lowered to a final drop position so that an emergency extinguishment can be discriminated from an ordinary extinguishment to perform an extinguishing operation.
