[0002] Heptafluoropropane fire extinguishing device is mainly a device filled with heptafluoropropane gas as the fire extinguishing agent.

[0003] The heptafluoropropane fire extinguishing agent in the heptafluoropropane fire extinguishing device is a colorless, odorless, non-conductive, and non-secondary pollution gas. It is clean, low-toxic, has good electrical insulation, and has high fire extinguishing efficiency. In particular, it has no damage to the ozone layer and has a relatively short residual time in the atmosphere. Its environmental performance is significantly better than that of halons. It is a relatively successfully researched and developed clean gas fire extinguishing agent and is considered to be the most ideal product to replace halons 1301 and 1211.

[0004] Traditional HFC-227ea fire extinguishing devices are usually stored in fire extinguishing boxes or on fixed racks. When a fire occurs, the user needs to lift the HFC-227ea fire extinguishing device with both hands, and then hold the fire extinguisher in one hand and the nozzle in the other hand to put out the fire. This method is more laborious and more troublesome for thinner people to use. In addition, when replenishing the fire extinguishing agent in the HFC-227ea fire extinguishing device, it also needs to be carried by manpower, which is time-consuming and labor-intensive.
