Abstract

A cartridge includes an air flow passageway defining a first airflow direction, a heating element having a longitudinal axis, the longitudinal axis perpendicular to the first airflow direction, and a jacket at least partially surrounding the heating element along the longitudinal axis of the heating element and defining a second airflow direction perpendicular to the first airflow direction.

First claim

What is claimed is:

1. An electronic vaping device, comprising:
a power section; and
a cartridge including,
an air flow passageway defining a first airflow direction,
a heating element having a longitudinal axis, the longitudinal axis being along a longitudinal axis direction, and the longitudinal axis direction being different from the first airflow direction, and
a jacket at least partially surrounding the heating element along the longitudinal axis of the heating element and defining a second airflow direction within the jacket, the second airflow direction being different from the first airflow direction.

2. The electronic vaping device as recited in claim 1 , wherein the jacket is arcuate.

3. The electronic vaping device as recited in claim 1 , wherein the jacket is a hollow cylinder.

4. The electronic vaping device as recited in claim 1 , wherein the jacket completely surrounds the heating element.

5. The electronic vaping device as recited in claim 1 , wherein the jacket comprises a heat insulator.

6. The electronic vaping device as recited in claim 5 , wherein the heat insulator is air impermeable and comprises fiberglass, ceramic or both fiberglass and ceramic.

7. The electronic vaping device as recited in claim 1 , further comprising:
an air inlet in the cartridge; and wherein
at least a part of the jacket is between the air inlet and the heating element.

8. The electronic vaping device as recited in claim 1 , wherein the jacket comprises an air permeable mesh.

9. The electronic vaping device as recited in claim 1 , further comprising:
a reservoir configured to store a pre-vapor formulation; and
a wick in fluid communication with the reservoir and the heating element;
wherein the jacket at least partially surrounds a portion of the wick.

10. The electronic vaping device as recited in claim 9 , wherein a segment of the wick is surrounded by the heating element.

11. The electronic vaping device as recited in claim 1 , wherein the longitudinal axis direction and the second airflow direction are a same direction.

12. A cartridge comprising:
an air flow passageway defining a first airflow direction;
a heating element having a longitudinal axis, the longitudinal axis being along a longitudinal axis direction, and the longitudinal axis direction being different from the first airflow direction; and
a jacket at least partially surrounding the heating element along the longitudinal axis of the heating element and defining a second airflow direction within the jacket, the second airflow direction being different from the first airflow direction.

13. The cartridge as recited in claim 12 , wherein the jacket is arcuate.

14. The cartridge as recited in claim 12 , wherein the jacket is a hollow cylinder.

15. The cartridge as recited in claim 12 , wherein the jacket completely surrounds the heating element.

16. The cartridge as recited in claim 12 , wherein the jacket comprises a heat insulator.

17. The cartridge as recited in claim 16 , wherein the heat insulator is air impermeable and comprises fiberglass, ceramic or both fiberglass and ceramic.

18. The cartridge as recited in claim 12 , further comprising:
an air inlet in the cartridge; and wherein
at least a part of the jacket is between the air inlet and the heating element.

19. The cartridge as recited in claim 12 , wherein the jacket comprises an air permeable mesh.

20. The cartridge as recited in claim 12 , further comprising:
a reservoir configured to store a pre-vapor formulation; and
a wick in fluid communication with the reservoir and the heating element;
wherein the jacket at least partially surrounds a portion of the wick.

21. The cartridge as recited in claim 20 , wherein a segment of the wick is surrounded by the heating element.

22. The cartridge as recited in claim 12 , wherein the longitudinal axis direction and the second airflow direction are a same direction.

23. The electronic vaping device as recited in claim 1 , wherein the first airflow direction is between the air flow passageway and the jacket.
