Sprinkler head

摘要

A sprinkler head includes a deflector attached to a first housing in a sealing-available manner; a locking unit for maintaining a sealing state between the deflector and the first housing; and a heat collecting unit exposed from the ceiling and reacted to heat when a fire breaks out. A locking groove is formed in a circumferential direction at an inner side with a prescribed height from a lower surface of a second housing and an air flow collecting portion is formed at a lower portion of the second housing to collect air flow heated when a fire breaks out and generates a swirl flow. The exposure distance of the sprinkler head from the ceiling surface is minimized so as to be protected from an external impact, and a reaction speed in case of occurrence of a fire can be faster for a prompt fire suppression.
