Aerosol delivery device including a pressure-based aerosol delivery mechanism

A method for aerosolization in an aerosol delivery device, comprising:

• directing an airflow from a control body through a cartridge comprising a reservoir at least partially filled with an aerosol precursor composition;
• controlling dispensing of the aerosol precursor composition from the reservoir to an atomizer comprising a chamber and a heating element positioned within the chamber based on a pressure differential between a first pressure within the reservoir and a second pressure proximate the atomizer;
• and
• heating the aerosol precursor composition dispensed from the reservoir into contact with the heating element to produce an aerosol in the chamber, the aerosol exiting the chamber before being added to the airflow,
• wherein directing the airflow from the control through the cartridge comprises directing the airflow into an opening, through the control body, into the cartridge, and out through a mouthpiece,
• wherein the atomizer is positioned between and spaced apart from the opening and the mouthpiece along a longitudinal axis of the aerosol delivery device such that the opening receives the airflow upstream of the atomizer.
