A carrier assembly for a spray device, which carrier assembly comprises a carrier member adapted to be mounted in a cartridge adapter of a spray device, which carrier member has a proximally directed first surface, and a through-hole placing the first surface in fluid communication with the second surface; a micro nozzle having an outlet surface, an inlet surface, and a channel placing an inlet orifice at the inlet surface in communication with an outlet orifice at the outlet surface and wherein the micro nozzle is accommodated and attached to the carrier member such that the outlet orifice is aligned with the through-hole, and wherein the carrier member comprises vent holes formed to allow air to flow between the second surface and the first surface.

Micro nozzle assembly

The present disclosure relates to a nozzle device for atomisation of a liquid, wherein the nozzle device comprises: a substrate, a sieve-side membrane comprising a plurality of sieve-side orifices, the sieve-side membrane being provided on a sieve-side of the substrate, a spray-side membrane comprising a plurality of spray-side orifices, the spray-side membrane being provided on a spray-side of the substrate, wherein the substrate has a first cavity portion extending to the sieve-side membrane, and a second cavity portion extending from the first cavity portion to the spray-side membrane, thereby providing fluid communication, along a fluid communication axis, between the sieve-side orifices and the spray-side orifices, the first cavity portion having a larger cross-sectional area than a cross-sectional area of the second cavity portion, the cross-sections being with respect to the fluid communication axis.
