Abstract

The present disclosure provides an aerosol delivery device and a cartridge for an aerosol delivery device. In various implementations, the aerosol delivery device comprises a control device that includes an outer housing defining a cartridge receiving chamber, and further includes a power source and a control component, and a cartridge that includes a mouthpiece, a tank, a heating assembly, and a bottom cap. The mouthpiece defines an exit portal in an end thereof, and the tank is configured to contain a liquid composition therein. The cartridge is configured to be removably coupled with the receiving chamber of the control device, and the heating assembly defines a vaporization chamber and is configured to heat the liquid composition to generate an aerosol. The heating assembly comprises a substantially planar heating member and a liquid transport element, wherein the heating member is installed in a bowed orientation.

First claim

The invention claimed is:

1. An aerosol delivery device comprising:
a control device including a power source and a control component; and
a cartridge that includes a heating assembly and a liquid composition,
wherein the cartridge is configured to be removably coupled with the control device, wherein the heating assembly is configured to heat the liquid composition to generate an aerosol, wherein the heating assembly comprises a substantially planar heating member and a liquid transport element, and wherein the heating member is installed in a bowed orientation, and
further comprising a base member into which the heating member and the liquid transport element are disposed, wherein at least one edge of the heating member is configured to engage the base member to facilitate the bowed orientation of the heating member.

2. The aerosol delivery device of claim 1 , wherein the heating member comprises a first end, a second end, and a heater loop connecting the first end and the second end.

3. The aerosol delivery device of claim 2 , wherein the heater loop comprises a serpentine pattern of connected heater traces that extend substantially transverse to a longitudinal axis of the heating member.

4. The aerosol delivery device of claim 3 , wherein the serpentine pattern of heater traces comprises a plurality of split traces located in a central area of the heating member.

5. The aerosol delivery device of claim 2 , wherein the heater loop is configured to concentrate heat in the area of the heating member in contact with the liquid transport element.

6. The aerosol delivery device of claim 1 further comprising a pair of connectors configured to electrically connect the cartridge with one or more of the control component or the power source.

7. The aerosol delivery device of claim 6 , wherein the heating member includes a pair of contact holes configured to connect the heating member to the connectors.

8. The aerosol delivery device of claim 6 , wherein each of the contact holes includes one or more extensions that create an effective inner diameter that is less than an outer diameter of the mating connector.

9. The aerosol delivery device of claim 1 , wherein the cartridge further includes a mouthpiece and a tank configured to contain the liquid composition, wherein the mouthpiece and the tank comprise the same part.

10. The aerosol delivery device of claim 1 , wherein the cartridge further includes a mouthpiece and a tank configured to contain the liquid composition, wherein the mouthpiece and the tank comprise separate parts.

11. A cartridge for use with an aerosol delivery device, the cartridge comprising:
a liquid composition; and
a heating assembly,
wherein the heating assembly is configured to heat the liquid composition to generate an aerosol, wherein the heating assembly comprises a substantially planar heating member and a liquid transport element, and wherein the heating member is installed in a bowed orientation,
further comprising a base member into which the heating member and the liquid transport element are disposed, wherein at least one edge of the heating member is configured to engage the base member to facilitate the bowed orientation of the heating member.

12. The cartridge of claim 11 , wherein the heating member comprises a first end, a second end, and a heater loop connecting the first end and the second end.

13. The cartridge of claim 12 , wherein the heater loop comprises a serpentine pattern of connected heater traces that extend substantially transverse to a longitudinal axis of the heating member.

14. The cartridge of claim 13 , wherein the serpentine pattern of heater traces comprises a plurality of split traces located in a central area of the heating member.

15. The cartridge of claim 12 , wherein the heater loop is configured to concentrate heat in the area of the heating element in contact with the liquid transport element.

16. The cartridge of claim 11 further comprising a pair of connectors configured to electrically connect the cartridge with a control device.

17. The cartridge of claim 16 , wherein the heating element includes a pair of contact holes configured to connect the heating member to the connectors.

18. The cartridge of claim 16 , wherein each of the contact holes includes one or more extensions that create an effective inner diameter that is less than an outer diameter of the mating connector.

19. The cartridge of claim 11 further comprising a mouthpiece and a tank configured to contain the liquid composition, wherein the mouthpiece and the tank comprise the same part.

20. The cartridge of claim 11 further comprising a mouthpiece and a tank configured to contain the liquid composition, wherein the mouthpiece and the tank comprise separate parts.

21. An aerosol delivery device comprising:
a control device including a power source and a control component; and
a cartridge that includes a heating assembly and a liquid composition,
wherein the cartridge is configured to be removably coupled with the control device, wherein the heating assembly is configured to heat the liquid composition to generate an aerosol, wherein the heating assembly comprises a substantially planar heating member and a liquid transport element, and wherein the heating member is installed in a bowed orientation,
wherein the heating member comprises a first end, a second end, and a heater loop connecting the first end and the second end, and wherein the heater loop comprises a serpentine pattern of connected heater traces that extend substantially transverse to a longitudinal axis of the heating member.

22. The aerosol delivery device of claim 21 , wherein the serpentine pattern of heater traces comprises a plurality of split traces located in a central area of the heating member.

23. The aerosol delivery device of claim 1 , wherein the cartridge further includes a mouthpiece and a tank configured to contain the liquid composition, wherein the mouthpiece and the tank comprise the same part.

24. The aerosol delivery device of claim 1 , wherein the cartridge further includes a mouthpiece and a tank configured to contain the liquid composition, wherein the mouthpiece and the tank comprise separate parts.

25. A cartridge for use with an aerosol delivery device, the cartridge comprising:
a liquid composition; and
a heating assembly,
wherein the heating assembly is configured to heat the liquid composition to generate an aerosol, wherein the heating assembly comprises a substantially planar heating member and a liquid transport element, and wherein the heating member is installed in a bowed orientation,
wherein the heating member comprises a first end, a second end, and a heater loop connecting the first end and the second end, and wherein the heater loop comprises a serpentine pattern of connected heater traces that extend substantially transverse to a longitudinal axis of the heating member.

26. The cartridge of claim 25 , wherein the serpentine pattern of heater traces comprises a plurality of split traces located in a central area of the heating member.

27. The cartridge of claim 25 further comprising a mouthpiece and a tank configured to contain the liquid composition, wherein the mouthpiece and the tank comprise the same part.
