Abstract

Example embodiments relate to a cartridge including a housing, a pre-vapor formulation reservoir configured to store a pre-vapor formulation in the housing, a vaporizer, and an airflow diverter. The vaporizer may be configured to vaporize the pre-vapor formulation. The vaporizer may include a heater and a wick, the wick may be in fluid communication with the pre-vapor formulation reservoir, and the heater may be configured to vaporize at least a portion of the pre-vapor formulation in the wick to form a vapor. The heater may be positioned in a transverse direction in the housing, and the airflow diverter may be located on an opposite side of the heater relative to a mouth-end portion.

First claim

The invention claimed is:

1. A cartridge, comprising:
a housing;
a pre-vapor formulation reservoir in the housing, the pre-vapor formulation reservoir configured to store a pre-vapor formulation;
a vaporizer configured to vaporize the pre-vapor formulation, the vaporizer including a heater and a wick, the wick being in fluid communication with the pre-vapor formulation reservoir, and the heater configured to vaporize at least a portion of the pre-vapor formulation in the wick to form a vapor; and
an airflow diverter configured to divert air around an outer edge of the airflow diverter and away from a central region of the heater,
wherein the heater is positioned in a transverse direction in the housing, and
wherein the airflow diverter is located on an opposite side of the heater relative to a mouth-end portion,
wherein the airflow diverter includes a convex surface or an acute-angled surface opposite the heater, and
wherein the airflow diverter is a unitary structure and orifice free.

2. The cartridge according to claim 1 , wherein the airflow diverter is substantially V-shaped in a cross-section along a longitudinal axis of the housing.

3. The cartridge according to claim 1 , wherein the airflow diverter is substantially C-shaped in a cross-section along a longitudinal axis of the housing.

4. The cartridge according to claim 1 , further comprising:
an inner tube within the housing, the inner tube including a pair of opposing slots, and
wherein an end portion of the vaporizer extends through one opposing slot in the pair of opposing slots.

5. The cartridge according to claim 4 , wherein the airflow diverter diverts air outwardly towards the inner tube.

6. The cartridge according to claim 4 , further comprising:
at least one air inlet located on an outer surface of the housing.

7. The cartridge according to claim 6 , wherein the at least one air inlet is near the mouth-end portion.

8. The cartridge according to claim 6 , wherein the at least one air inlet is at an end of the pre-vapor formulation reservoir closest to the mouth-end portion.

9. The cartridge according to claim 6 , wherein the at least one air inlet is disposed transversely in relation to the mouth-end portion.

10. The cartridge according to claim 6 , wherein the at least one air inlet is disposed at an angle in relation to the mouth-end portion.

11. The cartridge according to claim 10 , wherein the at least one air inlet is disposed at a 45 degree angle.

12. An e-vaping device, comprising:
a cartridge including,
a housing;
a pre-vapor formulation reservoir in the housing, the pre-vapor formulation reservoir configured to store a pre-vapor formulation;
a vaporizer configured to vaporize the pre-vapor formulation, the vaporizer including a heater and a wick, the wick being in fluid communication with the pre-vapor formulation reservoir, and the heater configured to vaporize at least a portion of the pre-vapor formulation in the wick to form a vapor; and
an airflow diverter configured to divert air around an outer edge of the airflow diverter and away from a central region of the heater,
wherein the heater is positioned in a transverse direction in the housing, and
wherein the airflow diverter is located on an opposite side of the heater relative to a mouth-end portion,
wherein the airflow diverter includes a convex surface or an acute-angled surface opposite the heater, and
wherein the airflow diverter is a unitary structure and orifice free; and
a power supply configured to supply power to the heater.

13. The e-vaping device according to claim 12 , wherein the airflow diverter is substantially V-shaped in a cross-section along a longitudinal axis of the e-vaping device.

14. The e-vaping device according to claim 12 , wherein the airflow diverter is substantially C-shaped in a cross-section along a longitudinal axis of the e-vaping device.

15. The e-vaping device according to claim 12 ,
wherein the cartridge further includes an inner tube within the housing, the inner tube including a pair of opposing slots, and
wherein an end portion of the vaporizer extends through one opposing slot in the pair of opposing slots.

16. The e-vaping device according to claim 15 , wherein the airflow diverter diverts air outwardly towards the inner tube.

17. The e-vaping device according to claim 12 , further comprising:
at least one air inlet located on an outer surface of the housing.

18. The e-vaping device according to claim 17 , wherein the at least one air inlet is near the mouth-end portion.

19. The e-vaping device according to claim 17 , wherein the at least one air inlet is at an end of the pre-vapor formulation reservoir closest to the mouth-end portion.

20. The e-vaping device according to claim 17 , wherein the at least one air inlet is disposed transversely in relation to the mouth-end portion.

21. The e-vaping device according to claim 17 , wherein the at least one air inlet is disposed at an angle in relation to the mouth-end portion.

22. The e-vaping device according to claim 21 , wherein the at least one air inlet is disposed at a 45 degree angle.

23. The e-vaping device according to claim 12 , further comprising a sheath flow and dispersion promoter insert near the mouth-end portion.

24. The e-vaping device according to claim 23 , further comprising:
at least one air inlet located on an outer surface of the housing, wherein
the sheath flow and dispersion promoter insert is superposed with the at least one air inlet.
