にした噴霧放水銃を提供せんとするものである。 In this invention, a valve that can be biased by a spring is installed in the gun body and connected to the flow channel, and this valve is formed so that it can be operated by a trigger.
A core with a flow path is supported and fixed inside the adapter attached to the gun body, an inner metal fitting is attached to the tip of this adapter, an outer metal fitting is slidably attached to the outside of this inner metal fitting, and the inner metal fitting is attached to the inner metal fitting. The nozzle to be installed in the space and the above-mentioned outer fitting are integrally connected, and a core is arranged at the base end of the flow channel in the nozzle so that it can be joined and separated by moving the nozzle forward and backward. Moreover, the core is formed with a flow path that opens from the outer part through the center part to the front end of the core,
Furthermore, a side flow channel and a swirler are provided in the space between the outside of the nozzle and the inner metal fitting, and the nozzle is moved back and forth to adjust the flow path between the core and the nozzle, thereby adjusting the amount of water flowing to the swirler and the amount of water inside the nozzle. Adjust the amount of water flowing through the flow channel, transform the water flow that flows into the swirler into a swirl flow, mix it with the pressure water in the nozzle, and mix the mist water and pressure water from the nozzle provided at the tip of the nozzle. By forming the water cannon so as to spray water, a straight stream flows into the center orifice of the water cannon and is ejected from the nozzle in a straight line, and a swirling spray water stream is created by a swirler installed at a point that passes outside the orifice and is adjacent to the nozzle. This spray water stream is mixed with the above-mentioned straight stream and ejected from the nozzle, and the spray water stream with a very large cooling area increases the fire extinguishing efficiency, and at the same time extinguishes the fire with a small amount of water, reducing water damage. It is an object of the present invention to provide a water spray gun that can prevent the above.
