Background Technology

[0002] A fire extinguisher is equipment designed to quickly suppress a fire when it occurs.

[0003] Among the types of fire extinguishers, foam extinguishers are fire extinguishers that utilize the principle of suppressing a fire by blocking oxygen through foam created when an extinguishing agent (e.g., foam extinguishing agent) mixes with water and air.

[0004] These foam fire extinguishers may be suitable for extinguishing fires caused by oil or chemicals.

[0005] Conventional powder fire extinguishers have a problem in that fine dust can be generated due to the high pressure during the spraying of the extinguishing agent. Additionally, some of the extinguishing agents used in conventional foam fire extinguishers contain components harmful to the environment.

[0006] Accordingly, the inventor(s) propose a technology regarding a foam fire extinguisher that prevents dust generation and simultaneously improves fire extinguishing performance by effectively mixing and spraying a fire extinguishing agent and a compressed fluid, including a compressed fluid tank and a spray module.
