Abstract

The present disclosure provides aerosol delivery devices. In an example implementation, an aerosol delivery device comprises an aerosol source member that defines an outer surface and an interior area and includes a substrate material having an aerosol precursor composition associated therewith, a control body having a housing that is configured to receive the aerosol source member, an electrical energy source coupled with the housing, and a heating assembly operatively connected to the electrical energy source. The heating assembly includes a plurality of spikes that may be configured to articulate between a retracted position, in which the plurality of spikes is not in contact with the aerosol source member, and a heating position, in which the plurality of spikes pierces through the outer surface of the substrate material and into a portion of the interior area thereof.

First claim

The invention claimed is:

1. An aerosol delivery device comprising:
an aerosol source member that defines an outer surface and an interior area and includes a substrate material having an aerosol precursor composition associated therewith;
a control body having a housing that is configured to receive the aerosol source member;
an electrical energy source coupled with the housing; and
a plurality of spikes comprising a heating assembly connected to the electrical energy source, the plurality of spikes extending along a longitudinal axis,
wherein the plurality of spikes pierce through the outer surface of the substrate material and into a portion of the interior area thereof.

2. The aerosol delivery device of claim 1 , wherein the outer surface of the substrate material includes a plurality of spaced conductive bands.

3. The aerosol delivery device of claim 2 , wherein each of the spaced conductive bands circumscribes the entire outer surface of the substrate material.

4. The aerosol delivery device of claim 2 , wherein each of the spaced conductive bands extends around a limited portion of the outer surface of the substrate material and defines a first end and a second end.

5. The aerosol delivery device of claim 4 , wherein respective spikes of the plurality of heat conducting spikes contact the first and second ends of the spaced conductive bands.

6. The aerosol delivery device of claim 1 , wherein the aerosol source member further comprises a second substrate material that defines an outer surface and an interior area, and wherein the second substrate material surrounds the first substrate material.

7. The aerosol delivery device of claim 6 , wherein the outer surface of the first substrate material includes a plurality of spaced conductive bands.

8. The aerosol delivery device of claim 7 , wherein each of the spaced conductive bands circumscribes the entire outer surface of the substrate material.

9. The aerosol delivery device of claim 7 , wherein each of the spaced conductive bands extends around a portion of the outer surface of the substrate material and defines a first end and a second end.

10. The aerosol delivery device of claim 9 , wherein in the heating position, respective spikes of the plurality of spikes contact the first and second ends of the spaced conductive bands.

11. The aerosol delivery device of claim 10 , wherein the plurality of spaced conductive bands comprises a heating member of the heating assembly.

12. The aerosol delivery device of claim 7 , wherein the plurality of spikes comprises a heating member of the heating assembly.

13. The aerosol delivery device of claim 6 , wherein the first substrate material comprises a first composition, wherein the second substrate material comprises a second composition, and wherein the first composition is different than the second composition.

14. The aerosol delivery device of claim 6 , wherein the first substrate material comprises at least one of shreds of tobacco material, beads of tobacco material, an extruded structure of tobacco material, a crimped sheet of tobacco material, and combinations thereof.

15. The aerosol delivery device of claim 6 , wherein the second substrate material comprises at least one of shreds of tobacco material, beads of tobacco material, an extruded structure of tobacco material, a crimped sheet of tobacco material, and combinations thereof.

16. The aerosol delivery device of claim 1 , wherein the substrate material comprises at least one of a tobacco material and a tobacco-derived material.

17. The aerosol delivery device of claim 1 , wherein the substrate material comprises a non-tobacco material.

18. The aerosol delivery device of claim 1 , wherein the substrate material comprises at least one of shreds of tobacco material, beads of tobacco material, an extruded structure of tobacco material, a crimped sheet of tobacco material, and combinations thereof.

19. The aerosol delivery device of claim 1 , wherein the plurality of spikes are configured to articulate to a retracted position, in which the plurality of spikes are not in contact with the aerosol source member.

20. The aerosol delivery device of claim 1 , wherein the longitudinal axis is parallel to the aerosol source member.
