Abstract

An aerosol delivery device is provided that comprises a control body and an aerosol source member. In various implementations, the control body includes a housing with an opening defined in one end thereof. The aerosol delivery device also includes a resonant transformer comprising a resonant transmitter and a resonant receiver. The aerosol source member includes an inhalable substance medium, and defines a heated end and a mouth end, the heated end configured, when inserted into the opening of the housing, to be positioned proximate the resonant transmitter. The resonant transmitter is configured to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver when exposed to the oscillating magnetic field, such that the alternating voltage causes the resonant receiver to generate heat and thereby vaporize components of the inhalable substance medium to produce an aerosol.

First claim

What is claimed is:

1. An aerosol delivery device comprising:
a control body having a housing with an opening defined in one end thereof;
a resonant transformer, the resonant transformer comprising a resonant transmitter and a resonant receiver;
and
an aerosol source member that includes an inhalable substance medium, the aerosol source member defining a heated end and a mouth end, the heated end configured to be positioned proximate the resonant transmitter,
wherein the resonant transmitter is configured to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver when exposed to the oscillating magnetic field, the alternating voltage causing the resonant receiver to generate heat and thereby vaporize components of the inhalable substance medium to produce an aerosol.

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

3. The device of claim 1 , wherein the resonant transmitter comprises a transmitter coil.

4. The device of claim 3 , further comprising a substantially cylindrical coil support member, and wherein the transmitter coil is configured to circumscribe the coil support member.

5. The device of claim 1 , wherein the resonant receiver comprises at least one receiver prong.

6. The device of claim 5 , wherein the at least one receiver prong comprises a single receiver prong extending from a receiver base member, and wherein the receiver prong is configured to be located in the approximate radial center of the heated end of the aerosol source member.

7. The device of claim 5 , wherein the at least one receiver prong comprises a plurality of receiver prongs extending radially from a receiver base member, and wherein the plurality of receiver prongs is configured to be located in the approximate radial center of the heated end of the aerosol source member.

8. The device of claim 1 , wherein the inhalable substance medium comprises a tube-shaped substrate, and wherein the resonant receiver extends into a cavity defined by an inner surface of the substrate.

9. The device of claim 8 , wherein the tube-shaped substrate comprises an extruded tobacco material.

10. The device of claim 1 , wherein the inhalable substance medium comprises a tube-shaped substrate that includes a braided wire structure, and wherein the braided wire structure comprises the resonant receiver.

11. The device of claim 1 , wherein the resonant receiver comprises a receiver cylinder.

12. The device of claim 3 , wherein the receiver cylinder circumscribes the inhalable substance medium.

13. The device of claim 1 , wherein the resonant transmitter comprises a laminate that includes a foil component.

14. The device of claim 1 , wherein the resonant receiver is constructed of a ferromagnetic material.

15. The device of claim 1 , further comprising a power source including a rechargeable supercapacitor, a rechargeable solid-state battery, or a rechargeable lithium-ion battery, the power source being configured to power the resonant transformer.

16. The device of claim 15 , wherein the power source further includes terminals connectable with a source of energy from which the rechargeable power source is chargeable.

17. The device of claim 1 , wherein the resonant transmitter is configured to at least partially surround the resonant receiver.

18. A control body for use with an aerosol source member that defines a heated end and a mouth end and includes an inhalable substance medium, the control body comprising:
a housing having an opening defined in one end thereof, the opening configured to receive the aerosol source member; and
a resonant transformer, the resonant transformer comprising a resonant transmitter and a resonant receiver,
wherein the resonant transmitter is configured to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver when exposed to the oscillating magnetic field, the alternating voltage causing the resonant receiver to generate heat, such that, when the aerosol source member is inserted into the control body, the resonant receiver is configured to vaporize components of the inhalable substance medium to produce an aerosol.

19. The control body of claim 18 , wherein the resonant transmitter comprises a transmitter coil.

20. The control body of claim 19 , further comprising a substantially cylindrical coil support member, and wherein the transmitter coil is configured to circumscribe the coil support member.

21. The control body of claim 18 , wherein the resonant receiver comprises at least one receiver prong.

22. The control body of claim 21 , wherein the at least one receiver prong comprises a single receiver prong extending from a receiver base member, and wherein, when the aerosol source member is inserted into the control body, the receiver prong is configured to be located in the approximate radial center of the heated end of the aerosol source member.

23. The control body of claim 21 , wherein the at least one receiver prong comprises a plurality of receiver prongs extending radially from a receiver base member, and wherein, when the aerosol source member is inserted into the housing, the plurality of receiver prongs is configured to be located in the approximate radial center of the heated end of the aerosol source member.

24. The control body of claim 18 , wherein the resonant receiver comprises a receiver cylinder.

25. The control body of claim 24 , wherein, when the aerosol source member is inserted into the control body, the receiver cylinder circumscribes the inhalable substance medium.

26. The control body of claim 18 , wherein the resonant transmitter comprises a laminate that includes a foil component.

27. The control body of claim 18 , wherein the resonant receiver is constructed of a ferromagnetic material.

28. The control body of claim 18 , further comprising a power source including a rechargeable supercapacitor, a rechargeable solid-state battery, or a rechargeable lithium-ion battery, the power source being configured to power the resonant transformer.

29. The control body of claim 28 , wherein the power source further includes terminals connectable with a source of energy from which the rechargeable power source is chargeable.

30. The control body of claim 18 , wherein the resonant transmitter is configured to at least partially surround the resonant receiver.
