In addition to being able to evolve, the manufacturing process is reduced to reduce the labor costs, and relates to a sprinkler head that can improve the work efficiency.

In general, the sprinkler head is installed on the ceiling of the building and connected to the water supply line for fire extinguishing to lock the switching member as the soft metal or glass bulb explodes at a set temperature (for example, 68 ° C. or 93 ° C.) in the event of a fire. By releasing the digestive water is ejected through the spout.

However, although the sprinkler head had a short time to reach the set temperature, there was a problem that the damage is uncontrollably increased by being caught in the fire in the meantime, thus forming a flush type sprinkler head using a glass bulb and thus the nominal release temperature. The sprinkler head has been developed and sold so that the sprinkler head is released by reacting early, and the sprinkler head is formed in a simple structure so that the glass bulb is broken and the spout is opened.
