Abstract

The invention provides a fire extinguisher. The fire extinguisher comprises a bracket, a steel cylinder, valves and a switch, and is characterized in that the steel cylinder consists of two parts of different sizes, wherein the two parts are respectively provided with the valves; the valves are respectively connected with the switch through guide pipes and are connected with the switch through a three-way joint. Compared with the prior art, the fire extinguisher provided by the invention has the advantages that ejected heptafluoropropane foams have a coverage and isolation function of foams and have a chemical inhibition function of heptafluoropropane gas; fire can be uniformly and densely covered, isolated and cooled; the fire extinguishment performance and the burn resistance are remarkably improved.

Description
