Abstract

Smoking articles, and methods for forming such smoking articles, such as an electronic smoking article, are provided. An exemplary smoking article comprises a control body portion having a control body engagement end, and having a first control component therein. A cartridge body portion includes a cartridge body engagement end configured to removably engage the control body engagement end of the control body portion. The cartridge body portion further includes a consumable arrangement comprising at least an aerosol precursor composition and at least one heating element operably engaged therewith, and a second control component. At least the consumable arrangement is configured to be in communication with the first control component upon engagement between the cartridge body and control body portions.

Claims23

Dependent claims

A smoking article comprising:

a control body portion having a control component therein;
and
a cartridge body portion configured to engage the control body portion, the cartridge body portion having a mouth end defining an opening, the cartridge body portion including:
a reservoir configured to store at least an aerosol precursor composition;
a resistive heating element operably engaged with the aerosol precursor composition so as to aerosolize the aerosol precursor composition to form an aerosol;
wherein the control component is configured to:
output a first electrical current flow in response to determining engagement of the control body portion with the cartridge body portion and authenticating the cartridge body portion;
output a second electrical current flow from an electrical power source to the resistive heating element in response to suction applied to the opening in the mouth end of the smoking article so as to aerosolize the aerosol precursor composition to form the aerosol;
and
selectively regulate the second electrical current flow through a regulator component of the control component and based at least in part on a resistance associated with the resistive heating element through a regulator component of the control component.
