In general, a fire extinguisher refers to a portable device that puts out a fire by using the effect of cooling or air blocking of a fire extinguishing agent in an extremely early stage of a fire. There are several types of fire extinguishers depending on the drug used or its mechanism, but currently used fire extinguishers include foam fire extinguishers, powder fire extinguishers, halon fire extinguishers, and carbon dioxide fire extinguishers.

Such a fire extinguisher includes a pressure-resistant container-shaped container in which the extinguishing agent is filled, a valve installed in the upper inlet of the container, and a nozzle part in the form of a tube connected to the valve. The valve is equipped with a pressure gauge and a handle. The nozzle section usually includes a flexible hose to ensure accurate spraying towards the fire point.

At this time, the type of extinguishing agent used may vary depending on the nature of the ignition material or the place where it is used. Recently, a fire extinguisher using an eco-friendly agent has been proposed to be used for civil or military use.

However, since the conventional fire extinguisher is made of heavy metal, there is a problem that it is difficult for children or the elderly to directly hold and use it due to its weight, and it is difficult to use it smoothly because it must be operated by rotating the lever after gripping it.

Here, by attaching or inserting locking pins made of a metal material to the inner surface of the oxygen fluorination container body 20 to be fixed, the powder extinguishing agent 30 collides by the stirring pin so that the powder extinguishing agent 30 is agglomerated It is desirable to prevent

In the case of a fire, the fire extinguisher 10 configured as described above throws the fire extinguisher 10 from the aircraft at the ignition point and collides with a tree or the ground, and the acid fluoride fire extinguishing container body 20 is crushed and the powdered fire extinguishing agent filled inside As (30) is scattered, it becomes possible to extinguish the fire.

In addition, it is possible to suppress the fire by throwing the fire bomb 10 in the air through a helicopter or a drone.

An aerial explosion means is further provided in the acid fluoride fire extinguishing body 20 to scatter the powdered extinguishing agent 30 filled by exploding in the air after being thrown from the aircraft.

The aerial explosive means includes an explosion housing 71 having a space therein which is fixed by bonding or screwing to the inner surface of the main body 20 for extinguishing acid fluoride, and gunpowder 72 filled in the explosion housing 71. ), a spark plug 73 attached to the inner surface of the explosion housing 71 to ignite the gunpowder 72, and a spark plug 73 formed in the explosion housing 71 to transmit a signal to the spark plug 73 It consists of a timer 74, and the wireless transmission/reception unit 75 is further provided in the main body 20 for fire extinguishing, so that an ignition signal is transmitted from the outside to transmit the ignition signal to the spark plug 73.

That is, after a set time has elapsed after being thrown from the aircraft to the ignition point, the timer 74 transmits a signal to the spark plug 73 to ignite the gunpowder 72 and explode, thereby setting the ignition point in the sky. 30) is scattered, so that the fire suppression efficiency can be improved and the suppression range can be expanded.

In addition, the user transmits a signal to the wireless transceiver 75 through the wireless terminal so that the gunpowder 72 is ignited through the spark plug 73, so that it is thrown from the aircraft under the control of the user and then explodes in the air. It is possible.

A compressed air scattering means 50 is further provided in the acid fluorination container body 20 to scatter the powdered extinguishing agent 30 filled by the compressed air filled therein.
