In general, a fire extinguisher refers to a fire extinguisher that uses fire extinguishing agents, such as cooling or air shutoff, in the early stages of fire.

There are many types of fire extinguishers, foam fire extinguishers, powder fire extinguishers, halon fire extinguishers, carbon dioxide fire extinguishers, etc., depending on the type of medicines or mechanisms used.

The dual powder fire extinguisher is a fire extinguisher that can be seen around the fire extinguisher by spraying powdered fire extinguishing agent in a container.

At this time, the fire extinguishing agent generates carbon dioxide gas by pyrolysis, and the fire is extinguished by suffocation and cooling.

The powder fire extinguisher is installed at a suitable place or entrance of a passageway where many people can know the installation place, and the early suppression of the fire can be performed quickly under the emergency of fire occurrence. .

As shown in FIG. 1, the powder fire extinguisher includes a fire extinguisher 10 filled with an extinguishing agent, a spray hose 20 connected to the fire extinguisher 10, A lever 30 provided between the barrel 10 and selectively communicating between the fire extinguisher 10 and the injection hose 20 and a safety pin 40 for locking or releasing the lever 30. [

In order to use the powder fire extinguisher having such a configuration, the safety pin 40 is pulled out of the lever 30 and the lever 30 is depressed with the restraint of the lever 30 released, So that the filled extinguishing agent is injected toward the flame through the injection hose 20 to be extinguished.

On the other hand, in order to use the powder fire extinguisher without causing a malfunction in an emergency, maintenance is required.

It is important to prevent the powdered fire extinguishing agent in the double fire extinguisher container 10 from curing. For this purpose, it is necessary to shake the fire extinguisher container 10 periodically at regular intervals to mix the fire extinguishing agent, or to place the fire extinguisher container 10 upside down for a predetermined period of time .

However, such a series of processes for preventing the fire-extinguishing of the fire extinguishing agent is performed manually, which is very troublesome, and thus, the fire extinguishing process can not be carried out periodically or at all.

Accordingly, when the fire extinguishing agent is hardened in the fire extinguisher container 10 and the fire extinguisher is not operated properly in the event of an emergency, the fire can not be suppressed at an early stage, causing a great fire accident.
