Abstract

Claims (26)

1. A cartridge for an aerosol provision system, wherein the cartridge comprises:

a heating element for heating aerosolizable material from a reservoir to generate aerosol;

an air channel extending through the cartridge for delivering air to the heating element; and

at least two contact electrodes mounted to the cartridge, wherein a portion of the air channel extends between the contact electrodes;

wherein each contact electrode comprises a portion defining a knurled outer surface which is embedded in a portion of the cartridge for securing the contact electrode to the portion of the cartridge, and

wherein the portion of the cartridge is molded around each contact electrode.

2. The cartridge according to claim 1 , wherein each contact electrode further comprises a flange portion which:

projects outwardly around the contact electrode; and

rests on a surface from the cartridge.

3. The cartridge according to claim 2 , wherein each contact electrode comprises no more than one of the flange portion.

4. The cartridge according to claim 2 , wherein the surface from the cartridge is an end surface from an end cap from the cartridge.

5. The cartridge according to claim 2 , wherein each flange portion has a thickness of no more than 1 mm.

6. The cartridge according to claim 1 , wherein each contact electrode is gold plated.

7. The cartridge according to claim 1 , wherein the cartridge comprises no more than two contact electrodes.

8. The cartridge according to claim 1 , wherein each contact electrode comprises a first end that is exposed at an interface end of the cartridge.

9. An aerosol provision system comprising the cartridge of claim 1 and a control unit, wherein the control unit comprises a receptacle that includes an interface arranged to cooperatively engage with the cartridge so as to releasably couple the cartridge to the control unit into a position where the cartridge is at least partially within the receptacle.

10. A method of securing a contact electrode to a cartridge of an aerosol provision system, the method comprising:

knurling an outer surface of the contact electrode; and

securing the contact electrode to the cartridge by way of the knurled outer surface being embedded in a portion of the cartridge, which is molded around the contact electrode.

11. The method according to claim 10 , wherein the method further comprises:

resting a flange portion of the contact electrode on a surface of the cartridge to support the contact electrode with respect to the cartridge.

12. The method according to claim 11 , wherein the flange portion projects outwardly around the contact electrode.

13. The method according to any of claim 10 , wherein the contact electrode is formed by a stamping process.

14. The method according to claim 10 , wherein the contact electrode is gold plated.

15. The method according to claim 10 , wherein securing the contact electrode to the cartridge further comprises:

mounting the contact electrode into an end cap of the cartridge.
