Abstract

Claims (41)

1. A method, comprising:

defining a reservoir within at least one first housing, the reservoir having a first part and a second part and being configured to contain a pre-vapor formulation;

defining at least one channel that is configured to communicate the pre-vapor formulation from the first part to the second part;

defining an airflow path within the at least one first housing; and

configuring a heater that is fluid permeable to heat and at least partially vaporize the pre-vapor formulation, the heater being on an end of the second part, the heater having a first surface that faces the first part, a first portion of the first surface being in direct communication with a second portion of the airflow path.

2. The method of claim 1 , further comprising:

inserting a capillary material within the second part, the capillary material directly abutting the heater.

3. The method of claim 1 , further comprising:

configuring a pair of electrical contacts to be in electrical contact with the heater.

4. The method of claim 3 , further comprising:

defining a pair of slots on sides of a heater mount, the heater mount at least partially containing the second part, the pair of slots being configured to at least partially contain the pair of electrical contacts.

5. The method of claim 4 , wherein the defining of the pair of slots at least partially defines the slots within a first wall and a second wall of the heater mount, the first wall defining an opening to expose the first portion of the first surface, the second wall being a sidewall of the heater mount that at least partially defines the second part, the first wall and the second wall being configured to respectively isolate the pair of electrical contacts from the second portion of the airflow path and the second part.

6. The method of claim 4 , further comprising:

defining an opening in a first wall, the opening being configured to expose the first portion of the first surface to the second portion of the airflow path.

7. The method of claim 6 , wherein the defining of the pair of slots at least partially defines the slots within the first wall and a second wall, the second wall is a sidewall that at least partially defines the second part, and surfaces of the first wall are perpendicular to the second wall.

8. The method of claim 1 , further comprising:

defining a pair of slots on sides of a heater mount, the heater mount at least partially containing the second part;

defining an opening in a wall of the heater mount, the opening being configured to expose the first portion of the first surface to the second portion of the airflow path, the wall including first major surfaces that respectively face the pair of slots; and

configuring contact pads on the first major surfaces, the contact pads being electrically connected to the heater and respectively connected to the pair of electrical contacts.

9. The method of claim 1 , further comprising:

configuring contact pads on first major surfaces of a first wall, the contact pads being electrically connected to the heater.

10. The method of claim 9 , further comprising:

defining an opening in the first wall, the opening being configured to expose the first portion of the first surface to the second portion of the airflow path.

11. The method of claim 10 , further comprising:

defining a pair of slots, at least in part, with the first wall and a second wall, the second wall being a sidewall that at least partially defines the second part, the first wall and the second wall being configured to respectively isolate the contact pads from the second portion of the airflow path and the second part.

12. The method of claim 1 , further comprising:

connecting a first housing to a second housing to form an assembly, the first housing containing the heater and at least partially defining the second part, the second housing defining the first part, the at least one first housing including the first housing and the second housing.

13. The method of claim 12 , wherein

the defining defines the at least one channel within the first housing, and

the connecting includes sliding an end of the first housing into the second housing such that at least a portion of the at least one channel extends into the second housing.

14. The method of claim 13 , further comprising:

inserting the assembly into an outer housing to form a cartridge.

15. The method of claim 14 , further comprising:

connecting a control section to the cartridge to form a device; and

defining an air inlet and an air outlet within the outer housing, the air inlet and the air outlet being in communication with the airflow path.

16. The method of claim 15 , further comprising:

configuring control circuitry and a power supply within the control section to be operatively connected to the heater in order to selectively send an electrical current to the heater when the control section is connected to the cartridge and the device is in operational use.

17. The method of claim 12 , wherein the defining defines the airflow path, at least in part, within the first housing and the second housing, the airflow path being defined when the first housing and the second housing are connected together.

18. The method of claim 1 , wherein the defining defines the at least one channel to be a first channel and a second channel on opposing sides of the heater.

19. The method of claim 1 , wherein the configuring configures the heater to include a plurality of electrically conductive filaments forming at least one of a mesh or a perforated plate.

20. The method of claim 1 , wherein the configuring configures the heater to be planar in shape, the first surface being flat.
