PURPOSE:To light or ring an alarm device or extinguish fire by a solenoid at the time of oxygen deficiency by providing a thermal deformation element within a combustion cylinder, and also providing an interlocking member actuating a switch being connected to a solenoid or an alarm device so as to respond to the thermal deformation element and an engaging element for engaging the interlocking member. CONSTITUTION:In the case of oxygen deficiency, the temperature at a position (in the vicinity of the inside of a combustion cylinder 4) where the temperature fluctuation appears more remarkably than the temperature at the time of normal combustion, displaces a thermal deformation element (such as a bimetal 5) provided within an inner flame cylinder 25. By this displacement force of the bimetal 5, and interlocking member 8 is moved by an interlocking member operating in linkage with a switch 6 by the force exerted by the displacement force of the bimetal 5 to operate the switch 6 and light or ring an alarm device 29 at the time of oxygen deficiency. That is, the interlocking member is disconnected from an engaging part by the displacement force of the bimetal 5, and a switch 6 is turned on by the force of a spring 10, and an alarm device 29 is lit or rung, or fire is extinguished by a solenoid 30. |
