Abstract

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices may include a control body, an atomizer body including an atomizer, and a cartridge including a reservoir configured to contain an aerosol precursor composition. The control body may be configured to releasably engage the atomizer body and the atomizer body may be configured to releasably engage the cartridge. The atomizer may be configured to receive an electrical current from the control body and the aerosol precursor composition from the cartridge to produce an aerosol.

First claim

The invention claimed is:

1. A cartridge for use in an aerosol delivery device, the cartridge comprising:
a reservoir configured to contain an aerosol precursor composition; and
an atomizer configured to vaporize the aerosol precursor composition,
wherein the atomizer comprises a flow director that includes a central inlet air channel and one or more radial inlet air holes configured such that air that enters through the central inlet air channel is directed through the one or more radial inlet air holes,
wherein the flow director further comprises one or more inlet vapor holes, and a transition barrier located between the one or more inlet air holes and the one or more inlet vapor holes such that air that enters through the inlet air channel is directed through the one or more radial inlet air holes by the transition barrier.

2. The cartridge of claim 1 , wherein the flow director has a “T” shape comprising an upper flange and a lower cylinder.

3. The cartridge of claim 2 , wherein the central air channel and the one or more radial inlet air holes are located in the lower cylinder.

4. The cartridge of claim 2 , wherein the one or more radial inlet air holes comprises a series of inlet air holes, and wherein the one or more inlet vapor holes comprises a series of inlet vapor holes.

5. The cartridge of claim 4 , wherein the series of inlet air holes and the series of inlet vapor holes are located in the lower cylinder.

6. The cartridge of claim 4 , wherein the series of inlet vapor holes lead to a series of radial vapor channels.

7. The cartridge of claim 6 , wherein the radial vapor channels lead to series of vertical vapor holes.

8. The cartridge of claim 7 , wherein the upper flange further defines a series of inlet liquid flow channels.

9. The cartridge of claim 1 , wherein the atomizer further comprises a liquid transport element.

10. A cartridge for use in an aerosol delivery device, the cartridge comprising:
a reservoir configured to contain an aerosol precursor composition; and
an atomizer configured to vaporize the aerosol precursor composition,
wherein the atomizer comprises a flow director that includes a central inlet air channel and one or more radial inlet air holes configured such that air that enters through the central inlet air channel is directed through the one or more radial inlet air holes,
wherein the flow director has a “T” shape comprising an upper flange and a lower cylinder,
wherein the one or more radial inlet air holes comprises a series of inlet air holes, the flow director further comprising a series of inlet vapor holes, and
wherein the series of inlet vapor holes lead to a series of radial vapor channels.

11. The cartridge of claim 10 , wherein the radial vapor channels lead to series of vertical vapor holes.

12. The cartridge of claim 11 , wherein the upper flange further defines a series of inlet liquid flow channels.

13. The cartridge of claim 10 , wherein the central air channel and the one or more radial inlet air holes are located in the lower cylinder.

14. The cartridge of claim 10 , wherein the series of inlet air holes and the series of inlet vapor holes are located in the lower cylinder.

15. The cartridge of claim 10 , wherein the atomizer further comprises a liquid transport element.

16. An aerosol delivery device comprising:
a cartridge; and
a control body, the control body being configured to releasably engage with the cartridge, the cartridge comprising:
a reservoir configured to contain an aerosol precursor composition; and
an atomizer configured to vaporize the aerosol precursor composition,

wherein the atomizer comprises a flow director that includes a central inlet air channel and one or more radial inlet air holes configured such that air that enters through the central inlet air channel is directed through the one or more radial inlet air holes,
wherein the flow director further comprises one or more inlet vapor holes, and a transition barrier located between the one or more inlet air holes and the one or more inlet vapor holes such that air that enters through the inlet air channel is directed through the one or more radial inlet air holes by the transition barrier.

17. The aerosol delivery device of claim 16 , wherein the flow director of the cartridge has a “T” shape comprising an upper flange and a lower cylinder.

18. The aerosol delivery device of claim 17 , wherein the central air channel and the one or more radial inlet air holes are located in the lower cylinder.

19. The aerosol delivery device of claim 17 , wherein the one or more radial inlet air holes comprises a series of inlet air holes, and wherein the one or more inlet vapor holes comprises a series of inlet vapor holes.

20. The aerosol delivery device of claim 19 , wherein the series of inlet air holes and the series of inlet vapor holes are located in the lower cylinder.

21. The aerosol delivery device of claim 19 , wherein the series of inlet vapor holes lead to a series of radial vapor channels.

22. The aerosol delivery device of claim 21 , wherein the radial vapor channels lead to series of vertical vapor holes.

23. The aerosol delivery device of claim 22 , wherein the upper flange further defines a series of inlet liquid flow channels.

24. The aerosol delivery device of claim 16 , wherein the atomizer further comprises a liquid transport element.

25. An aerosol delivery device comprising:
a cartridge; and
a control body, the control body being configured to releasably engage with the cartridge, the cartridge comprising:
a reservoir configured to contain an aerosol precursor composition; and
an atomizer configured to vaporize the aerosol precursor composition,

wherein the atomizer comprises a flow director that includes a central inlet air channel and one or more radial inlet air holes configured such that air that enters through the central inlet air channel is directed through the one or more radial inlet air holes,
wherein the flow director of the cartridge has a “T” shape comprising an upper flange and a lower cylinder,
wherein the one or more radial inlet air holes comprises a series of inlet air holes, the flow director further comprising a series of inlet vapor holes, and
wherein the series of inlet vapor holes lead to a series of radial vapor channels.

26. The aerosol delivery device of claim 25 , wherein the radial vapor channels lead to series of vertical vapor holes.

27. The aerosol delivery device of claim 26 , wherein the upper flange further defines a series of inlet liquid flow channels.

28. The aerosol delivery device of claim 25 , wherein the central air channel and the one or more radial inlet air holes are located in the lower cylinder.
