(Function) In such a fire detection device, the shutter 4 is normally in a closed state, and the fire detection sensor 3 is not visible. When a fire breaks out and a predetermined temperature is reached, the shape memory alloy spring 6 is activated, and the force opens the shutter 4, exposing the fire detection sensor 3 and detecting the fire. I start to feel better. Also,
When there is only smoke without a significant temperature upper limit, the shape memory alloy spring 6 does not operate, thereby preventing false detection.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3. The fire detection device of this embodiment has a sensor storage chamber 1
An electric fire detection sensor 3, for example, for detecting a flame fire, is installed in the Renley storage chamber 2. A frontage 1A of the sensor housing chamber 1 is closed with a shutter 4.

A shape memory alloy spring 6 is installed on the front side of the container 2 adjacent to the shutter 4, one end of which is fixed to the container 2, and the other end fixed to the shutter 4. Shape memory alloy spring 6
The material has shape memory so that it contracts when it reaches a predetermined temperature (for example, 50° C.). A recess 7 is provided in the container 2 so that the shape memory alloy spring 6 can be accommodated therein.

sensor 3 is hidden. When a fire occurs and a predetermined temperature is reached, the shape memory alloy spring 6 is activated and contracts, and the force at that time pulls the shutter 4, the sensor housing chamber 1 listens, and the sensor 3 detects the fire. It becomes a state. In the case of simple smoke from grilled fish, etc., without a luxurious upper limit of temperature, the shape memory alloy spring 6 does not operate and the shutter 4 does not listen.
