Automatic fire extinguisher capable of discharging fire-extinguishing agent to fire site

摘要

The present invention relates to an automatic fire extinguisher capable of automatically discharging a fire-extinguishing agent upon the occurrence of a fire. More particularly, the present invention relates to an automatic fire extinguisher which is capable of automatically discharging a fire-extinguishing agent to a fire site without using power upon the occurrence of a fire to thus efficiently extinguish the fire, and which is also capable of sounding an alarm at an early stage upon the occurrence of a fire, to thus enable people to take swift action. The automatic fire extinguisher of the present invention may ultimately serve as a sprinkler, and can be reused after operation.

主权项

1. An automatic fire extinguishing discharger comprising:
a plurality of first bimetals which are disposed at constant angular intervals in a plurality of directions and are deformed when a certain temperature or more is reached due to occurrence of a fire; trigger switches which are rotated by a certain angle from a restrained position to an operational position by deformation of the first bimetals; a trigger disc which is rotated by a certain angle by operations of the trigger switches; a gear trigger which is moved from a restrained position to an operational position by rotation of the trigger disc; a following gear which is restrained or released by the gear trigger; an operation spring which provides the following gear with a driving force; a crank pin which engage a crank stopper of the trigger switch in an operational position; a cam which is rotated by a certain angle by the driving force of the operation spring when the crank pin engages the crank stopper; a valve pin which is pressed by the cam to thereby open a fire-extinguishing agent valve; and a fire-extinguishing agent spray nozzle which is disposed such that it communicates with the fire-extinguishing agent valve and is rotated in the same direction as the crank pin.
