Description

Grenade type fire extinguisher

The present invention relates to a fire extinguisher, and more particularly, a compressed container containing compressed air and a fire extinguishing liquid are put in the case, and the compressed container and the case are made of a material with high thermal conductivity. It is a grenade-type fire extinguisher that can explode and spray extinguishing fluid as it expands.

When a fire occurs, various fire extinguishers are used to extinguish it. A common type of fire extinguisher is a spray type fire extinguisher that uses a hose to spray the extinguishing liquid directly to the place where the fire occurred.

The spray type fire extinguisher pulls out the safety pin and shakes it, then points the hose to the area where the fire occurred, and then presses the handle to turn off the fire. Therefore, there may be a risk to safety.

In recent years, in order to solve this problem, a throwable fire extinguisher that is thrown at a place where a fire occurs has been developed.

The patent has a spherical shape and an inner receiving space, the outer shell having a through hole formed on one side; a retardant that is stored in the accommodating space inside the shell and is a fire extinguishing powder; a safety pin for blocking the through hole of the shell; a thermal sensor provided on the inner circumferential surface of the outer shell and configured to measure the temperature of external air introduced through the through hole; and a primer provided inside the shell to ignite the retardant when the temperature of the outside air measured by the heat sensor exceeds a set temperature, and air introduced from the outside between the shell and the accommodating space. There is disclosed a fire-fighting grenade in which a movement path is formed. The complex shape of the outer shell increases the manufacturing cost, and the fire extinguishing powder, a retardant, is sprayed only when the temperature is raised by the heat sensor, so heat is directly applied. There is a problem that the grenade may not explode when it is thrown into an unsettled area.

In addition, there is a problem in that the portion to which the retardant is sprayed is not entirely and can be sprayed only to one side by configuring the blocking shell between the shells.

As another prior art, there is a grenade-type fire extinguisher proposed in Patent Publication No. 10-2012-0056386.
