Abstract

An electronic cigarette vaporizer that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the delivery of power, current or voltage to the heating element and (ii) determines if those characteristics are associated with degradation of the heating element. A characteristic that is associated with degradation of the heating element is an increase or other change in the heating element resistance. The heating element resistance can be established by the electronics module sending a test current through the heating element that is sufficient to enable a measurement of resistance to be made.

Claims

1. An electronic cigarette vaporiser system that includes an electronic vaporiser, a heating element in the electronic vaporiser and further includes an electronics module that (i) detects characteristics of the delivery of power, current or voltage to the heating element and (ii) determines if those characteristics are associated with degradation of the heating element, in which the electronic vaporiser system includes (i) a user-replaceable, e-liquid cartridge, which is not user-refillable and includes no heating element;

and (ii) an e-liquid reservoir that is separate from the user-replaceable e-liquid cartridge; and

(iii) an electric or electronic pump that is configured to withdraw e-liquid from the user-replaceable e-liquid cartridge and pump pressurized e-liquid to the e-liquid reservoir; and

(iv) the heating element that is not in the user-replaceable e-liquid cartridge but is instead in, or in e-liquid communication with, the e-liquid reservoir.

2. The electronic vaporiser system of claim 1 in which a characteristic that is associated with degradation of the heating element is an increase or other change in the heating element resistance.

3. The electronic vaporiser system of claim 2 in which the heating element resistance is established by the electronics module sending a test current through the heating element that is sufficient to enable a measurement of resistance to be made.

4. The electronic vaporiser system of claim 3 in which the test current is set at a level or a duration that the temperature of the heating element is not raised to a vaping temperature of 130 degrees C.

5. The electronic vaporiser system of claim 2 in which if the electronics module measures a resistance of the heating element, higher than a preset threshold, then that is indicative of a degraded heating element.

6. The electronic vaporiser system of claim 1 in which the electronics module stores a record of the measured characteristics and determines if those stored records indicate fluctuations that are indicative of degradation of the heating element.

7. The electronic vaporiser system of claim 1 in which the electronics module generates a signal indicating that the heating element should be replaced.

8. The electronic vaporiser system of claim 7 in which the signal causes a visual indication to be given on the vaporiser and/or a case into which the vaporiser is stored and/or a device that is wirelessly connected to the case.

9. The electronic vaporiser system of claim 1 in which the vaporiser includes a power source and the electronics module.

10. The electronic vaporiser system of claim 1 in which the vaporiser is stored in a case that includes a power source and electronics module.

11. The electronic vaporiser system of claim 1 in which the electronic vaporiser is an e-cigarette system.

12. The electronic vaporiser system of claim 1 in which the electronic vaporiser is a medicinally approved nicotine drug delivery system.

13. The electronic vaporiser system of claim 1 in which the electronic vaporiser is the same approximate size as a cigarette.

14. The electronic vaporiser system of claim 1 in which the electronic vaporiser is the same approximate size as a cigarette and includes no control buttons.

15. The electronic vaporiser system of claim 14 in which the electronic vaporiser is automatically activated when it detects that it has been withdrawn from a case that otherwise stores the vaporiser.

16. The electronic vaporiser system of claim 13 in which the electronic vaporiser has a square or rectangular cross-section with rounded corners and includes a long PCB inserted lengthwise into the vaporiser.

17. The electronic vaporiser system of claim 1 in which the electronic vaporiser has a squircle cross-section.

18. The electronic vaporiser system of claim 1 in which the electronic vaporiser is only re-fillable from the user-replaceable closed, e-liquid cartridge.

19. The electronic vaporiser system of claim 1 in which the electronic vaporiser that includes the heating element is refillable with e-liquid only when inserted, whole and intact and not dis-assembled, into a re-fill case that includes a fluid transfer mechanism to transfer e-liquid into the vaporiser from the user-replaceable closed, e-liquid cartridge.

20. The electronic vaporiser system of claim 1 including a case for storing the electronic vaporiser.

21. The electronic vaporiser system of claim 20 in which the case includes the electric or electronic pump.

22. The electronic vaporiser system of claim 1 in which the electronic vaporiser includes the electric or electronic pump and the user-replaceable cartridge is removably insertable or integral to the vaporiser.
