Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a fire extinguishing water gun with an adjustable spraying mode. Background Art

[0002] A fire-fighting water gun is a fire-fighting equipment used to extinguish fires. By connecting to a water hose, the fire-fighting water gun can spray out dense and substantial water flow. It has the advantages of long range and large water volume. According to the different jet forms and characteristics, fire-fighting water guns can be divided into direct current water guns and spray water guns. Direct current water guns are the main equipment used by firefighters when extinguishing fires. They can convert the high-pressure water flow in the water hose into a high-speed jet and spray it onto objects in the fire scene to achieve the purpose of extinguishing the fire.

[0003] In actual use, in some places where the fire is large or high, a direct current water gun is needed to spray long distances for fire extinguishing. When the fire is small or under control, a spray water gun with a wide spray coverage is needed to quickly extinguish the fire in order to save fire water. However, the spraying mode of the fire extinguishing water gun is inconvenient to adjust, and firefighters need to replace the fire extinguishing water gun, which reduces the fire extinguishing efficiency and is very inconvenient to operate. Therefore, it is in urgent need of improvement. Utility Model Content
