To provide a liquid spray nozzle or the like capable of reducing drift by maintaining the accessible performance nearly equal to that of a conventional liquid spray nozzle for spraying liquid droplets having relatively large mean particle diameter, and preferably, capable of improving the deposition property further than that.
The present invention relates to a liquid spray nozzle 4 for spraying liquid, a sprayer 2 provided therewith, and a nozzle head 10 for use therein. The liquid spray nozzle 4 has a spray port 12 with large particle diameter for spraying liquid droplets LS with large particle diameter, and a spray port 14 with small particle diameter for spraying liquid droplets SS with small particle diameter smaller than the liquid droplets LS with large particle diameter. The spray port 12 is arranged near the spray port 14 so that the liquid droplets SS sprayed from the spray port 14 are carried while having them on the stream of the liquid droplets LS sprayed from the spray port 12.
