Abstract: A microstructured passage module for aerosol generator is provided. The module includes a plate overlaid by a cover thus forming a compartment, an entrance for a liquid and an exit. The plate includes a plurality of walls parallel to each other over its entire width so as to define a plurality of passages therebetween. Moreover, a plurality of pillars protruding from the plate are distributed in at least section of the passages. A column is disposed proximate to the exit and blocks a substantial part thereof, leaving longitudinal aisles for the liquid to flow towards the exit. The liquid flows through the compartment from the entrance to the exit such that an aerosol is produced. A distance between two adjacent pillars is D and the longitudinal aisle has a width W. The D and the W are specifically configured such that the aerosol has a predetermined MMAD.

Abstract: An aerosol generating apparatus is disclosed. The apparatus includes a liquid container, an adaptor detachably engaged with the liquid container, and a driving element accommodated by the adaptor. A perforated membrane, through which a liquid can pass through, is disposed at an exit of the liquid container. Moreover, the perforated membrane faces the driving element. The driving element includes a substrate coupled with a piezoelectric element. The substrate includes an aperture that corresponds to the perforated membrane when the liquid container and the adaptor are engaged so as to receive liquid. Moreover, when the liquid container and the adaptor are engaged, the perforated membrane is in contact with the substrate at the proximity of the aperture, which is about the substrate's center. The adaptor is configured to contact the substrate's periphery only. The resulting apparatus generates aerosol at a desired efficiency with less energy needed.
