Title: NOZZLE DEVICE AND A METHOD OF MANUFACTURING THE SAME
Abstract:
The present disclosure relates to a nozzle device (1-1) for atomisation of a liquid, wherein the nozzle device (1-1) comprises: a substrate (3), a sieve-side membrane (5) comprising a plurality of sieve-side orifices (5a), the sieve-side membrane (5) being provided on a sieve-side (3c) of the substrate (3), a spray-side membrane (7) comprising a plurality of spray-side orifices (7a), the spray-side membrane (7) being provided on a spray-side (3d) of the substrate (3), wherein the substrate (3) has a first cavity portion (4a) extending to the sieve-side membrane (5), and a second cavity portion (4b) extending from the first cavity portion (4a) to the spray-side membrane (7), thereby providing fluid communication, along a fluid communication axis (9), between the sieve-side orifices (5a) and the spray-side orifices (7a), the first cavity portion (4a) having a larger cross-sectional area (11) than a cross-sectional area (13) of the second cavity portion (4b), the cross-sections being with respect to the fluid communication axis (9).
