[0002] Perfluorohexanone is a green and environmentally friendly fire extinguishing agent, which mainly relies on heat absorption to achieve the effect of fire extinguishing. The fire extinguishing concentration of perfluorohexanone is 4-6%, and the safety margin is relatively high, which is safer for the human body when used. In addition, perfluorohexanone is a liquid at room temperature and is not a dangerous item. It can be safely stored and transported in ordinary containers under normal pressure.

[0003] For example, a non-pressurized perfluorohexanone fire extinguishing device disclosed in announcement number CN218980309U includes a housing, a perfluorohexanone medicine bag, and an aerosol agent. The non-pressurized perfluorohexanone fire extinguishing device is easy to install, has a small size, and has a simple structure assembly. It can be used in small spaces such as electrical cabinets. When started, the aerosol generates high temperature to vaporize the perfluorohexanone liquid, and the aerosol gas and the vaporized perfluorohexanone agent are ejected from the nozzle on the nozzle mounting plate, diffused into the fire extinguishing space, and quickly extinguished the fire.

[0004] However, during the use of the current non-pressurized perfluorohexanone fire extinguishing device, the fire can only be responded to and extinguished after the fire is discovered and the device is manually used and operated.

[0005] Therefore, how to provide a non-pressurized perfluorohexanone fire extinguishing device that can detect fire in time and start the fire extinguishing procedure to ensure the timeliness and effectiveness of fire extinguishing is a technical problem that needs to be solved urgently by technical personnel in this field.
