[0002] A fire-fighting sprayer is a device specially designed for extinguishing fires. It usually consists of a pressure tank filled with fire extinguishing agent, a nozzle and an operating rod or button. The working principle of the fire-fighting sprayer is to use the stored pressure to release the fire extinguishing agent into the fire scene, thereby extinguishing the flames or controlling the fire.

[0003] Although current technology has many advantages, the disadvantage of current technology is that most traditional fire-fighting sprayers occupy the space inside the fire truck, resulting in a reduction in the space for other fire-fighting equipment in the fire truck. The fire-fighting sprayers cannot be quickly dismantled and installed on the chassis of the car, resulting in a large amount of idle space on the chassis of the car, which cannot be fully utilized. It is not convenient for manual rapid disassembly and use, which affects manual operation and reduces the practicality of the fire-fighting sprayers. In addition, traditional fire-fighting sprayers can only use three fire-extinguishing agents, namely, water, foam, and dry powder, separately. When encountering a fire, they cannot be selected promptly and quickly according to different fire situations, which greatly reduces the fire-fighting effect of the fire-fighting sprayers and reduces the emergency function of the fire-fighting sprayers.
