The first nozzle portion is provided with an air guide path for high pressure air in the middle, and provided with a spraying port(140) in a lower side of the air guide path. The second nozzle portion is provided with a washing liquid guide path for high pressure washing liquid in a position in contact with the air guide path of the first nozzle portion, and provided with a spraying surface in a lower side of the washing liquid guide path. The separating plate is inserted between the first nozzle portion and the second nozzle portion, and has a lower surface provided with a plurality of minute grooves(310) in a transverse direction and coupled to a bottom surface of the washing liquid guide path.
