CLOSED TYPE FIRE EXTINGUISHING HEAD

PROBLEM TO BE SOLVED: To provide a closed type fire extinguishing head in which a support which supports a thermosensitive body does not affect the radiation distribution of a fire extinguishing agent, and which is not easily deformed even when the support is undertaken with force from the thermosensitive body.SOLUTION: The closed type fire extinguishing head 1 is equipped with a fire extinguishing head body 10 with a discharge hole 101, a pip cap 11 which is brought into contact with the discharge hole 101 to be freely detached and attached, a thermosensitive body 15 which supports the pip cap 11, a guard frame 12 which supports the thermosensitive body 15, and a ball 13 which is supported by the fire extinguishing head body 10 and supports the guard frame 12. A part of the guard frame 12 projects outward from the fire extinguishing head body 10. A part of the thermosensitive body 15 is exposed outside from the guard frame 12 in either direction nearly perpendicular to the projecting direction of the guard frame 12. In a state that the thermosensitive body 15 is not deformed, the ball 13 is supported from the fire extinguishing head body 10 by the thermosensitive body 15. The guard frame 12 is supported by the ball 13. In the state that the thermosensitive body 15 is deformed, the ball 13 and so on are freely detached and attached from/to the fire extinguishing head body 10.
