Aerosol delivery device including a positive displacement aerosol delivery mechanism

An aerosol delivery device, comprising:

• a cartridge comprising a base and a reservoir at least partially filled with an aerosol precursor composition;
• and
• a control body comprising a coupler,
• the base and the coupler being configured to direct the aerosol precursor composition from the reservoir therethrough to an atomizer comprising a heating element configured to heat the aerosol precursor composition received from the reservoir to form a vapor,
• wherein the cartridge is configured to receive an airflow from the control body through the coupler and the base.

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;
• dispensing the aerosol precursor composition from the reservoir to an atomizer comprising a heating element with a positive displacement apparatus;
• and
• heating the aerosol precursor composition dispensed from the reservoir with the heating element to produce an aerosol.
