Abstract
A nozzle body (1) for a liquid droplet spray device is disclosed, wherein the nozzle body is arranged to receive a liquid substance from the liquid droplet spray device, wherein the nozzle body includes: (a) a substrate (2), and (b) a plurality of traversing output nozzles (4, 24, 34) formed in the substrate (2, 22, 32) for ejecting liquid as a low pressure mono-dispersive droplet spray, wherein each traversing output nozzle is arranged to receive the liquid such that the liquid may be expelled from the nozzle body by traversing the output nozzles, wherein the output nozzles (4, 24, 34) have straight and parallel side-walls that have a near vertical profile. The output nozzles are arranged in the substrate such that the density of the output nozzles increases from the center towards the edges of the substrate.
