Description

Technical Field

[0001] The utility model relates to the technical field of spray guns, and more specifically to a novel fire extinguishing spray gun. Background Art

[0002] A fire hose is a water-shooting tool for extinguishing fires. When connected to a water hose, it will spray dense and substantial water flows. It has the advantages of long range and large water volume. New energy vehicles refer to vehicles that use new power systems and are completely or mainly driven by new energy. When a new energy vehicle catches fire, a fire hose is generally used to remotely spray the burning material to achieve the effect of extinguishing the fire.

[0003] In actual use, the existing fire extinguishing spray gun generally adopts a fire water gun with a long range for long-distance fire extinguishing. However, due to the long range, it is impossible to cool down at close range, which affects the fire extinguishing efficiency to a certain extent. If it is to be sprayed at close range, there are certain safety hazards and it is inconvenient to use. Therefore, there is an urgent need to improve the technology of the structure of the fire extinguishing spray gun to improve this equipment. Utility Model Content
