PURPOSE: A sprinkler nozzle for an automatic extinguishing device is provided to extinguish fire at an initial state by supplying extinguishing liquid with even spraying distribution and density on a protection area which must be under control in case a fire breaks out. CONSTITUTION: A sprinkler nozzle for an automatic extinguishing device is attached to the upper area of a gas range for a kitchen. The sprinkler nozzle sprays extinguishing liquid which been passed through a screw(R10) with radiation pressure for amplifying using a bottleneck phenomenon, to form uniform distribution and density. The sprinkler nozzle sets a generation part in which fire should be extinguished with a surrounding area as a protection area as the distribution and the density of the extinguishing liquid controls a fire extinguishing work while the extinguishing liquid works automatically in real time. Initial extinguishing work of a kindling object is achieved in few seconds by forming even sprinkle distribution and density through making the protection area in a sprinkle area during sprinkling.
