Abstract

The present disclosure provides a control body, an aerosol delivery device, and a method of operating an aerosol delivery device. In various implementations, the aerosol delivery device comprises a control body having a housing, an electrical energy source located within the housing, a heating member operatively connected to the electrical energy source, an aerosol source member that includes an inhalable substance medium, and an indexing mechanism coupled to the heating member. The indexing mechanism is configured to move the heating member relative to the aerosol source member so as to sequentially heat one of two or more segments of the aerosol source member.

First claim

The invention claimed is:

1. An aerosol delivery device, comprising:
a control body having a housing;
an electrical energy source located within the housing;
a heating member operatively connected to the electrical energy source;
an aerosol source member that includes an inhalable substance medium; and
an indexing mechanism coupled to the heating member,
wherein the indexing mechanism is configured to move the heating member relative to the aerosol source member so as to sequentially heat at least one of two or more segments of the aerosol source member, and wherein the indexing mechanism comprises a motor, a lead screw, and a carrier to which the heating member is affixed.

2. The aerosol delivery device of claim 1 , wherein the heating member is located proximate an external surface of the aerosol source member.

3. The aerosol delivery device of claim 1 , wherein the heating member is located proximate an internal surface of the aerosol source member.

4. The aerosol delivery device of claim 1 , wherein the indexing mechanism is activated by a sensor configured to detect a draw on the aerosol source member.

5. The aerosol delivery device of claim 1 , wherein the indexing mechanism is activated by a manual button.

6. The aerosol delivery device of claim 1 , wherein the aerosol source member is removably engaged with the control body and replaceable.

7. The aerosol delivery device of claim 1 , wherein the inhalable substance medium of the aerosol source member comprises a solid or semi-solid inhalable substance medium.

8. The aerosol delivery device of claim 7 , wherein the inhalable substance medium comprises an extruded substrate.

9. A control body for use with an aerosol source member that includes an inhalable substance medium, the control body comprising:
a housing;
an electrical energy source located within the housing;
a heating member operatively connected to the electrical energy source; and
an indexing mechanism coupled to the heating member,
wherein the indexing mechanism is configured to move the heating member relative to the aerosol source member so as to sequentially heat at least one of two or more segments of the aerosol source member, and wherein the indexing mechanism comprises a motor, a lead screw, and a carrier to which the heating member is affixed.

10. The control body of claim 9 , wherein the indexing mechanism is activated by a sensor configured to detect a draw on the aerosol source member.

11. The control body of claim 9 , wherein the indexing mechanism is activated by a manual actuator.

12. A method of operating an aerosol delivery device that includes a control body and an aerosol source member, said method comprising:
energizing a heating member using an electrical energy source located in a housing of the control body;
heating a first segment of the aerosol source member using the heating member;
moving the heating member relative to the aerosol source member from a first position to a second position using an indexing mechanism; and
heating a second segment of the aerosol source member using the heating member,
wherein the indexing mechanism comprises a motor, a lead screw, and a carrier to which the heating member is affixed.

13. The method of claim 12 , wherein heating the first and second segments of the aerosol source member comprises initially heating an external surface of the first and second segments of the aerosol source member.

14. The method of claim 12 , wherein heating the first and second segments of the aerosol source member comprises initially heating an internal surface of the first and second segments of the aerosol source member.

15. The method of claim 12 , further comprising activating the indexing mechanism using a sensor configured to detect a draw on the aerosol source member.

16. The method of claim 12 , further comprising activating the indexing mechanism using a manual actuator.
