Abstract
A sprinkler head having a first housing connected to a water supply pipe disposed inside a building ceiling. The sprinkler head includes a second housing coupled to the first housing and fixed to the ceiling surface. A deflector is adhered to the first housing for spraying water by being detached from the first housing. A locking unit is locked inside the second housing for maintaining the sealing state between the deflector and the second housing, and a heat responding unit is exposed to outside of the ceiling for sensing heat at the time of a fire occurrence and thus releasing a locking of the locking unit.
Claims4
A sprinkler head comprising:
- a first housing connected to a water supply pipe disposed inside a building ceiling;
- a second housing coupled to the first housing and fixed to the ceiling surface;
- a deflector adhered to the first housing in a sealing-available manner for spraying water all around at the time of a fire occurrence by being detached from the first housing;
- a locking unit locked inside the second housing for maintaining the sealing state between the deflector and the second housing;
- and
- a heat responding unit exposed to outside of the ceiling for sensing heat at the time of a fire occurrence and thus releasing a locking of the locking unit;
- wherein the second housing is provided with a locking groove formed in a circumferential direction at an inner side with a prescribed height from a lower surface of the second housing and an air flow collecting portion for collecting air flow heated when a fire breaks out and generating a swirl flow;
- and
- the locking unit having a locking ring locked at the locking groove and first and second loading plates for pressurizing the locking ring thus to widen is inserted into the second housing.
