Abstract

The present disclosure relates to aerosol delivery devices that may include components configured to convert electrical energy to heat and atomize an aerosol precursor composition. An outer body may at least partially enclose the components. An illumination source may be configured to output electromagnetic radiation. A wave guide may be configured to receive the electromagnetic radiation from the illumination source and illuminate the aerosol delivery device. The wave guide may define an increasing width from a first longitudinal end at which the electromagnetic radiation is received to an opposing second longitudinal end. Thereby, the wave guide may directly transmit the electromagnetic radiation across the entirety of the second longitudinal end to provide substantially even illumination at the second longitudinal end while employing less material and reducing the volume of space occupied by the wave guide as compared to cylindrical embodiments of wave guides. Related methods are also provided.

First claim

The invention claimed is:

1. An aerosol delivery device, comprising:
an outer body extending between a first outer body end and a second outer body end, the outer body being at least partially hollow;
an illumination source configured to output an electromagnetic radiation; and
a wave guide disposed within the outer body, the wave guide comprising a length extending between a first longitudinal end and a second longitudinal end and a width extending between a first lateral end and a second lateral end, wherein the wave guide is bent into a defined shape for placement within the outer body and extends from the illumination source to one or more illumination sections disposed about an outside portion of the outer body, and wherein the wave guide is configured to receive the electromagnetic radiation from the illumination source and output light at the one or more illumination sections.

2. The aerosol delivery device of claim 1 , wherein the width of the wave guide is greater at the second longitudinal end than at the first longitudinal end.

3. The aerosol delivery device of claim 1 , wherein the wave guide defines a T-shape prior to insertion within the outer body.

4. The aerosol delivery device of claim 1 , wherein the wave guide defines a truncated triangular shape prior to insertion into the outer body.

5. The aerosol delivery device of claim 1 , further comprising an electrical power source and a control component, the control component being configured to direct current from the electrical power source to an atomizer.

6. The aerosol delivery device of claim 1 , wherein the wave guide is flexible.

7. The aerosol delivery device of claim 6 , wherein the wave guide comprises a sheet of material wrapped into a substantially tubular configuration,
the wave guide defining an outer diameter substantially equal to an inner diameter of the outer body.

8. The aerosol delivery device of claim 1 , further comprising a coupler coupled to the first outer body end; and
an end cap coupled to the second outer body end, the second longitudinal end of the wave guide being positioned proximate the end cap.

9. The aerosol delivery device of claim 8 , further comprising a cartridge, wherein the outer body, the coupler, the end cap, the illumination source, and the wave guide collectively define a control body,
the cartridge being configured to engage the coupler of the control body.

10. The aerosol delivery device of claim 1 , wherein the one or more illumination sections include the second longitudinal end of the wave guide.

11. The aerosol delivery device of claim 10 , wherein the one or more illumination sections include an intermediate illumination section positioned between the first longitudinal end and the second longitudinal end of the wave guide.

12. A method for assembling an aerosol delivery device, the method comprising:
coupling an illumination source configured to output an electromagnetic radiation to a first longitudinal end of a wave guide, the wave guide extending between the first longitudinal end and a second longitudinal end, the wave guide being configured to receive the electromagnetic radiation from the illumination source and output light at one or more illumination sections;
bending the wave guide; and
inserting the wave guide within an outer body, the outer body being at least partially hollow, such that the wave guide extends from the illumination source to the one or more illumination sections disposed about an outside portion of the outer body.

13. The method of claim 12 , wherein the wave guide has a width extending between a first lateral end and a second lateral end and transversely to a longitudinal length extending between the first longitudinal end and the second longitudinal end, and wherein the width of the wave guide is greater at the second longitudinal end than at the first longitudinal end and wherein bending the wave guide comprises abutting or overlapping the first lateral end and the second lateral end at the second longitudinal end of the wave guide.

14. The method of claim 13 , wherein bending the wave guide comprises bending the wave guide from a T-shape.

15. The method of claim 13 , wherein bending the wave guide comprises bending the wave guide from a truncated triangular shape.

16. The method of claim 12 , wherein bending the wave guide comprises wrapping a sheet of material into a substantially tubular configuration such that the wave guide defines an outer diameter substantially equal to an inner diameter of the outer body.

17. The method of claim 12 , further comprising inserting an electrical power source and a control component within the outer body, the control component being configured to direct current from the electrical power source to an atomizer.

18. The method of claim 12 , further comprising coupling a coupler to a first outer body end; and
coupling an end cap to a second outer body end such that the second longitudinal end of the wave guide is positioned proximate the end cap.

19. The method of claim 18 , further comprising coupling the coupler to a cartridge.

20. The method of claim 14 , wherein inserting the wave guide within the outer body comprises resiliently pressing the wave guide against an inner circumference of the outer body.

21. The method of claim 12 , wherein coupling the illumination source to the first longitudinal end of the wave guide comprises orienting the illumination source perpendicularly to the second longitudinal end of the wave guide such that the one or more illumination sections include the second longitudinal end.

22. The method of claim 21 , further comprising engaging a refractor with a core of the wave guide between the first longitudinal end and the second longitudinal end of the wave guide to define an intermediate illumination section.

23. The aerosol delivery device of claim 2 , wherein the first lateral end abuts or overlaps the second lateral end along at least a portion of the longitudinal length of the wave guide.

24. An aerosol delivery device, comprising:
an outer body extending between a first outer body end and a second outer body end, the outer body being at least partially hollow;
an illumination source configured to output an electromagnetic radiation;
a wave guide disposed within the outer body, the wave guide extending between a first longitudinal end and a second longitudinal end and extending from the illumination source to one or more illumination sections disposed about an outside portion of the outer body, wherein the wave guide is configured to receive the electromagnetic radiation from the illumination source and output light at the one or more illumination sections;
a coupler coupled to the first outer body end; and
an end cap coupled to the second outer body end, the second longitudinal end of the wave guide being positioned proximate the end cap.
