Abstract: An aerosol-generating device is provided, including a first atomiser assembly including a first mesh element defining a plurality of first nozzles each having a minimum diameter of equal to or less than 2.5 micrometres; a second atomiser assembly including a second mesh element defining a plurality of second nozzles each having a minimum diameter of between 3 micrometres and 10 micrometres; a first device connector configured to receive a first liquid reservoir and to supply a first liquid from the first liquid reservoir to the first atomiser assembly; and a second device connector configured to receive a second liquid reservoir and to supply a second liquid from the second liquid reservoir to the second atomiser assembly.

Abstract: A mesh element for an atomiser assembly is provided, including: a first layer defining at least one channel including a minimum cross-sectional area; and a second layer overlying the first layer and defining at least one nozzle including a maximum cross-sectional area, the second layer including an inner surface facing the first layer and an outer surface facing away from the first layer, the at least one nozzle overlying the at least one channel, and the maximum cross-sectional area of the at least one nozzle being smaller than the minimum cross-sectional area of the at least one channel, and the outer surface of the second layer defining an annular portion extending around the at least one nozzle, the annular portion having a semi-circular cross-sectional shape, and a thickness of the second layer at each annular portion being larger than a thickness of the second layer between adjacent annular portions.
