<P>PROBLEM TO BE SOLVED: To provide a sprinkler head capable of more uniformly ejecting a fire extinguishing liquid to be emitted therefrom. <P>SOLUTION: The sprinkler head includes: a discharge section 2 having a discharge port for discharging a fire extinguishing liquid; a deflector 6 formed like a disc and opposite to the discharge port; and a coupling section 7 for coupling the deflector 6 to the discharge section 2. The deflector 6 has a plurality of flange portions 61 segmented by a plurality of slits 60 formed with equal spaces and in a diameter direction on an outer peripheral portion; and a base section 62 formed integrally with the plurality of the flange portions 61. The coupling section 7 includes a pair of frames 70 which protrude from the discharge section 2 toward the outer peripheral direction in a diameter direction of the deflector 6 and are coupled to the center of the deflector 6. In the sprinkler head with the structure, through holes 63a, 63b penetrating through front and rear surfaces are formed in the base section 62, thereby improving the uniformity of the supply of the fire extinguishing liquid in a fire fighting area. <P>COPYRIGHT: (C)2012,JPO&INPIT |
