Nebulization generating apparatus

An aerosol generating apparatus comprising:

• a liquid source with a perforated membrane through which a liquid can pass through;
• an adaptor detachably engaged with the liquid container, and the adaptor includes an interface configured to receive the liquid source;
• and
• a driving element operatively connectable to the adaptor and including a piezoelectric element and a substrate, the substrate including an aperture positionally aligned with a center of the substrate that corresponds to the perforated membrane when the liquid container and the adaptor are engaged,
• wherein the adaptor further includes at least one extension for supporting a predetermined location on a periphery of the substrate,
• wherein the at least one supporting extension includes a first surface, the first surface extending along a direction perpendicular to a longitudinal axis of the adaptor,
• wherein the substrate includes an upper surface facing the membrane and an opposite lower surface,
• wherein the lower surface is in direct contact only with the first surface of the at least one supporting extension and the substrate is maintained at a predetermined distance from an inner surface of the adaptor when the substrate sits on the supporting extension,
• wherein a liquid flow direction is defined as from the upper surface to the lower surface,
• wherein the substrate sits on the first surface along the liquid flow direction, and
• wherein when provided with electric power, the piezoelectric element vibrates the perforated membrane, through which the liquid passes and aerosolizes.

An aerosol generating apparatus comprising:

• a liquid container including a perforated membrane through which a liquid can pass through;
• an adaptor configured to be detachably engaged with the liquid container;
• and
• a driving element including a piezoelectric element coupled to a substrate, wherein the driving element is operatively connectable to the adaptor, and the substrate includes an aperture positionally aligned with the perforated membrane when the liquid container and the adaptor are engaged,
• wherein the aperture is aligned with the center of the substrate, and the adaptor is configured to contact the substrate,
• wherein the adaptor includes at least one jack for directly contacting only a predetermined location on a periphery of the substrate,
• wherein the at least one jack further comprises a first surface, and the first surface extends along a direction perpendicular to a longitudinal axis of the adaptor such that the predetermined location on the periphery of the substrate sits on and is in contact only with the first surface,
• wherein the substrate includes an upper surface facing the membrane and an opposite lower surface,
• wherein predetermined location on the periphery at the lower surface of the substrate is in direct contact only with the first surface while the lower surface is maintained at a predetermined distance from an inner surface of the adaptor when the substrate sits on the at least one jack, and
• wherein during operation the aerosol generating apparatus is held upright where the liquid enters the perforated membrane from an inlet surface of the perforated membrane and exits the perforated membrane from an outlet surface of the perforated membrane due to gravity, and the substrate is positionally aligned with the adaptor via the at least one jack during operation.
