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 resistance of the heating element and (ii) uses an inference of temperature derived from that resistance as a control input. The temperature of the heating element may be inferred from data stored in the electronics module that has been empirically obtained for a specific heating element design. The electronics module controls the power delivered to the heating element to ensure that it is no higher than approximately 130° C., plus an error tolerance.

Claims

1. An electronic cigarette vaporiser system that includes an electronic vaporiser, wherein the electronic vaporiser includes a heating element and further includes an electronics module that (i) detects characteristics of the resistance of the heating element and (ii) uses an inference of temperature derived from that resistance as a control input;

in which the electronic vaporiser system includes (i) a user-replaceable, e-liquid cartridge that is attached to or integral with the system whilst the system is being vaped by an end-user, but 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 pressurised e-liquid to the e-liquid reservoir; and

in which (iv) the heating element 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 the temperature of the heating element is inferred from data stored in the electronics module that has been empirically obtained for a specific heating element design.

3. The electronic vaporiser system of claim 1 in which the electronics module controls the power delivered to the heating element to ensure that it is no higher than approximately 130°

C., plus an error tolerance.

4. The electronic vaporiser system of claim 1 in which the electronics module controls the power delivered using the resistance measurement and does not calculate any derived temperature.

5. The electronic vaporiser system of claim 1 in which the electronics module applies multiple techniques designed to ensure the heating element is at its optimal heating temperature, including estimating heating element resistance, and weights the signals from each technique.

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

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

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

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

10. The electronic vaporiser system of claim 1 in which the electronic vaporiser is automatically activated when it detects that it has been withdrawn from a case that otherwise stores the vaporiser.

11. The electronic vaporiser system of claim 1 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.

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

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

14. The electronic vaporiser system of claim 1 in which the electronic vaporiser 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 a user-replaceable closed, e-liquid cartridge.

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

16. The electronic vaporiser system of claim 15 in which the case includes the electric or electronic pump.

17. 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.
