The vapor-forming units are connectable to a power unit.
Claims17
An aerosol delivery device comprising:
- a housing extending between a mouthend and a connector end;
- a mouthpiece at the mouthend of the housing;
- a connector at the connector end of the housing;
- a flow tube arranged within the housing;
- a reservoir for an aerosol precursor composition defined between the flow tube and the housing;
- and
- an atomizer comprising a liquid transport element that is formed of a porous ceramic and a heating element, wherein the liquid transport element extends between a first end and a second end and has a hollow interior that defines an open passage that extends between the first end and the second end of the liquid transport element, and wherein the heating element is positioned at least partially within the open passage of the liquid transport element;
- wherein the liquid transport element sealingly engages the flow tube and at least a portion of the liquid transport element is received through at least a portion of the flow tube so as to be within the flow tube, such that the open passage defined by the hollow interior of the liquid transport element aligns with a path extending through the flow tube.
