Supersonic-speed jet-flow fire-extinguishing assembly and fire extinguisher

The invention provides a supersonic-speed jet-flow fire-extinguishing assembly and a fire extinguisher, and relates to the technical field of fire protection engineering. The supersonic-speed jet-flowfire-extinguishing assembly comprises a jet-flow high-pressure gas cylinder used for storing a supersonic-speed jet-flow gas source, a water path high-pressure gas cylinder used for storing water, agas-water mixing part and a gas path pipeline, wherein the jet-flow high-pressure gas cylinder and the water path high-pressure gas cylinder separately communicate with the gas-water mixing part; thejet-flow high-pressure gas cylinder communicates with the gas pipeline through the gas-water mixing part; the gas-water mixing part communicates with a water path fine tube; and the water path high-pressure gas cylinder communicates with the water path fine tube through the gas-water mixing part. According to the supersonic-speed jet-flow fire-extinguishing assembly provided by the invention, gas-water mixing is combined wi
