Description

Portable fire extinguisher {PORTABLE FIRE EXTINGUISHER}

The present invention relates to a portable fire extinguisher.

In general, a fire extinguisher is a machine or apparatus for extinguishing using water or other extinguishing agents, and is used for initial suppression in the event of a fire in a building, a vehicle, a ship, and the like. It usually takes some time before the fire truck arrives after a fire breaks out, so small embers can turn into a fire and grow into a large fire. However, there are many situations where there is no fire extinguisher in the vicinity of the fire, and the fire extinguishers are difficult to move due to their bulky and heavy weight, and thus fail to suppress the initial suppression.

Extinguishers that are currently commercially available have a common sense, such as liquid fire extinguisher, powder fire extinguishers, carbon dioxide (CO ₂₎ gas-based fire extinguishers and aerosol solid (aerosol) automatic fire extinguishing system, such as a fire extinguisher.

In the case of the liquid and powder fire extinguisher, it is impossible to use nitrogen gas when leaking, and there is a disadvantage in that secondary damage occurs in electrical and electronic equipment. In addition, the powder and carbon dioxide fire extinguisher is difficult to use for the first person, children and senior citizens using heavy fire extinguisher due to the heavy and high radial pressure. The solid aerosol automatic fire extinguishing device has a disadvantage in that it cannot be operated artificially because it is a product that operates automatically when a high temperature is detected.

Therefore, the function of the fire extinguisher for the initial fire suppression, as well as the minimum weight and volume of the fire extinguisher can be used easily and safely by anyone, to prevent secondary damage to the equipment and human body caused by the extinguishing agent, and also difficult to secure visibility There is a need for a portable fire extinguisher capable of visual and auditory alarms in situations.
