Background

Fire fighting vehicles, which are specialized vehicles that fire fighters use to perform fire-fighting tasks, are also used for other emergency rescue purposes by most national fire departments, including china. The fire engine can transport firefighters to a disaster site and provide a variety of tools for performing disaster relief tasks. Common fire fighting vehicle types include water tank fire fighting vehicles, foam fire fighting vehicles, pump fire fighting vehicles, elevating platform fire fighting vehicles, aerial ladder fire fighting vehicles, and the like. At present, fire extinguishing agents which can be combined in multiple groups, such as 2019113522657 (a solid-liquid bi-component foam extinguishing agent) or 2019113530352 (a general-purpose high-stability foam extinguishing agent), are mixed with water to generate foam, and then the foam is used for extinguishing fire. When the existing fire engine uses the fire extinguishing agent which can be used in a multi-group combined mode, due to the fact that the mixing time of the fire extinguishing agent and water is short, a high-efficiency fire extinguishing covering cannot be formed, and the fire extinguishing efficiency and the burning resistance time of the existing fire engine need to be improved.
