Abstract

An aerosol delivery device is provided that comprises a control body and an aerosol source member. The aerosol delivery device includes a resonant transformer comprising a resonant transmitter and a resonant receiver. The aerosol source member includes an inhalable substance medium at least a portion of which is 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. In some implementations, the resonant receiver comprises part of the control body. In other implementations, the resonant receiver comprises part of the aerosol source member.

First claim

What is claimed is:

1. An aerosol delivery device comprising:
a control body;
a resonant transmitter; and
an aerosol source member that includes an aerosol precursor composition and a resonant receiver,
wherein the aerosol source member is configured to be coupled to the control body, wherein the resonant transmitter is located within the control body and 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 aerosol precursor composition to produce an aerosol,
wherein the resonant transmitter comprises a transmitter coil, wherein the control body further comprises a coil support member, wherein the transmitter coil is configured to circumscribe the coil support member, and wherein the resonant receiver has a rectangular cross-section.

2. The aerosol delivery device of claim 1 , wherein the resonant receiver is located in the approximate radial center of the aerosol source member.

3. The aerosol delivery device of claim 1 , wherein the coil support member includes one or more coil grooves configured to receive the transmitter coil.

4. The aerosol delivery device of claim 1 , wherein the transmitter coil substantially surrounds the resonant receiver.

5. The aerosol delivery device of claim 1 , wherein the transmitter coil comprises a helical coil.

6. The aerosol delivery device of claim 1 , wherein the coil support member has a tubular configuration.

7. The aerosol delivery device of claim 1 , wherein the transmitter coil has a substantially circular cross section.

8. The aerosol delivery device of claim 1 , wherein the coil support member is made of a nonconductive material.

9. The aerosol delivery device of claim 1 , wherein the coil support member is made of one or more plastic materials.

10. The aerosol delivery device of claim 1 , wherein the transmitter coil extends along a majority of a longitudinal length of the resonant receiver.

11. The aerosol delivery device of claim 1 , wherein the transmitter coil extends along substantially all of a longitudinal length of the resonant receiver.

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

13. The aerosol delivery device of claim 1 , further comprising a power source located in the control body including a lithium-ion battery, the power source being configured to power the resonant transmitter.

14. The aerosol delivery device of claim 1 , wherein an opening is defined in an end of the control body, and wherein the aerosol source member is coupled to the control body via the opening.

15. The aerosol delivery device of claim 1 , wherein the aerosol precursor composition comprises a liquid.

16. The aerosol delivery device of claim 1 , wherein spaces are located between adjacent individual coils of the transmitter coil.

17. The aerosol delivery device of claim 1 , wherein adjacent individual coils of the transmitter coil contact each other.

18. The aerosol delivery device of claim 1 , wherein the coil support member is substantially cylindrical.

19. The aerosol delivery device of claim 1 , wherein the control body further includes a control component configured to control the resonant transmitter.

20. The aerosol delivery device of claim 1 , wherein the control body further includes a puff sensor.
