Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a high-flow-rate, multi-functional fire-fighting foam gun. Background Technology

[0002] Fire hoses typically extinguish fires by spraying water. In some cases, compressed air foam is used for fire extinguishing. When fire hoses use sprayed foam to extinguish fires, the foam covers the burning material, which, in addition to cooling it, can isolate the transfer of flammable vapors, air, and heat, thus achieving the effect of extinguishing the fire.

[0003] A water and foam integrated fire hose, with application number "CN202321436264.2", allows for the connection of a water pipe via an internal thread at the water pipe connection port. The water pipe connects to a fire hydrant and is then connected to a water source. Personnel can adjust the angle of the hose by raising the bottom of the nozzle using the extended end of a hydraulic cylinder to suit different spray angles at fire scenes. The angle can also be raised using a handle. However, when extinguishing fires at low locations, the hydraulic cylinder and supporting arc block prevent the nozzle from rotating downwards, making it inconvenient for firefighting at low points. Utility Model Content
