To solve the problem that since there is one water spray port of a conventional nozzle, when water is sprayed towards the ceiling, water cannot be simultaneously sprayed in the floor direction and in the horizontal direction, and when water is sprayed towards the floor, reactional force given to a fire fighter operates in the direction in which the fire fighter is lifted up and weight of a hose becomes heavier than when water is sprayed towards the ceiling, so that although it is effective to fire extinction to spray water towards the floor, water cannot be sprayed towards the floor and a phreatic explosion occurs in the case that water is sprayed towards the floor.

The reactive force is reduced by spraying water to the floor in the direction opposite to the ceiling direction and the reactional force is reduced by spraying water in the left direction opposite to the right direction, and water is sprayed onto the floor with several meters' width.
