Fire extinguishers are one of the most common firefighting equipment and are used to extinguish initial fires. Fire hoses and water guns are used to supply water for firefighting and send water to the source of the fire for firefighting operations. Fire hoses are soft pipes that are usually connected to fire hydrants or fire pumps, and water is sprayed onto the fire scene through water guns or nozzles.

[0003] Fire hose is a water-jetting tool for firefighting. When connected with a water hose, it will spray dense and substantial water flow. It has the advantages of long range and large water volume. According to the different jet forms and characteristics, it can be divided into: direct current water gun, spray water gun, multi-use water gun, etc. Among them, the commonly used water guns are direct current and spray water guns. The current fire hose still has shortcomings when used:

[0004] Fire hoses are mostly handheld, which makes it inconvenient to support the hoses for a long time and requires a lot of physical effort;
