{POWDER FIRE EXTINGUISHER OF EXPLOSIVE SCATTERING TYPE}

The present invention relates to an explosive scattering type powder fire extinguisher, and more particularly, to an explosive scattering type powder fire extinguisher that enables rapid extinguishing response to the direction of a fire source through a fuse arrangement structure that promotes ease of crushing. About.

In general, fire extinguishers are equipment for extinguishing fires using fire extinguishing agents, and must be provided throughout large facilities such as buildings, subways, ships, etc. in accordance with fire fighting regulations. These fire extinguishers may be classified into solid powder fire extinguishers, liquid fire extinguishers, gas fire extinguishers, and the like according to the state of the material of the fire extinguishing agent to be filled.

Such a fire extinguisher is used in a manner in which the user presses the handle and injects the extinguishing agent filled in the hollow case toward the fire source to extinguish the fire.

However, although conventional fire extinguishers are widely used for initial extinguishing purposes of fires, there is a problem in that the extinguishing capacity is greatly reduced in the case of failure of the initial extinguishing or in the case of a strong fire.

In addition, in a conventional fire extinguisher, in an urgent state, such as when a fire occurs, the user must carry a fire extinguisher and approach the fire site to perform extinguishing work.However, the double operation in which the extinguishing agent is sprayed is not performed until the user removes the safety pin and presses the handle Because it is necessary, there is a problem that causes the failure of early evolution.

On the other hand, in the case of a sprinkler that is fixedly installed on the ceiling of a building and sprays a powdery solid or liquid fire extinguishing agent in the event of a fire, it is superior to conventional fire extinguishers, but operates until it reaches a certain temperature. As it is not, there is a limit to use it for initial fire extinguishing purposes. In addition, since the sprinkler typically sprays a large amount of water during its operation, there is an unsuitable problem in extinguishing fires related to oil products.

Recently, as a means of early extinguishing in the event of a fire, a throwing fire extinguisher capable of extinguishing a fire in the early stage by simply throwing it toward a fire source has been developed and used.

However, the conventional explosive scattering type powder fire extinguisher, which is one of the known throwing fire extinguishers, has a problem in that it does not provide a fuse arrangement structure that facilitates crushing while enabling rapid fire extinguishing response to the direction of the fire source. have.
