ABSTRACT:
A sprinkler head comprises: a locking unit locked inside a second housing for maintaining a sealing state between a deflector and a first housing; a heat responding unit exposed to outside of a ceiling for releasing the locked state of the locking unit by reacting to fire when fire breaks out; and a head cover mounted at a lower side of the heat responding unit and transmitting heat to the heat responding unit after collecting heat at the time of a fire occurrence. According to this, a fine appearance of the sprinkler head is provided, and the head cover performs a heat collecting function at the time of a fire occurrence thus to have a fast reaction speed, thereby enhancing a function of the sprinkler head.
