As shown in FIG. 2, the nozzle 14 is inserted into the ejector mixing tube 10 via the air inlet 18 and detachably fixedly coupled to the ejector mixing tube 10. The outer wall surface of the nozzle 14 is fitted to the inner wall surface of the ejector mixing tube 10. The upper end surface of the side portion of the nozzle 14 is higher than the lowest end of the waist hole 32 in the axial direction of the bow mixing tube 10. Thus, when the long lamp is operated on a rainy day, the liquid entering the ejector mixing tube 10 flows out from the waist hole 32 along the upper end surface of the side portion of the nozzle to prevent corrosion of the nozzle 14 due to the formation of the liquid.

In particular, the nozzle 14 includes an integrally formed nozzle base 34, a flow tube 36 extending from the nozzle base 34, and a nozzle head 38 extending from the flow tube 36, such as a tapered nozzle head 38.
