This utility model discloses a multifunctional fire hose, including a hose. The hose features a continuous array of arched protrusions in its anti-slip layer, periodically arranged along the hose's axis, providing multidirectional and continuous friction. This effectively reduces slippage when firefighters push, pull, or twist the hose, making the operation more reliable. The vents in the protective layer ensure good air permeability while preventing dust and debris from entering, providing reliable protection for the load-bearing layer. The first color-changing zone in the load-bearing layer, relying on an activated carbon adsorption layer and chemically sensitive capsules, can promptly indicate the presence of toxic gases. The second color-changing zone, aided by a conductive tape and a heat-sensitive capsule, can quickly indicate high-temperature areas. These two color-changing zones are staggered along the hose and, with the separation of spacers, achieve independent responses, avoiding interference between signals. This allows firefighters to quickly and accurately assess on-site risks, significantly improving the safety and overall efficiency of firefighting operations.
