Abstract

An electronic cigarette vaporiser that is the same approximate size as a cigarette and has a square or rectangular cross-section with rounded corners and includes a long PCB inserted lengthwise into the vaporiser. The PBC is not mounted at the mid-point of the cross-section, but at a different position closer to a major face of the vaporiser to permit more room for a rechargeable battery. The cross-section is a ‘squircle’.

First claim

The invention claimed is:

1. An electronic cigarette vaporiser system that includes an electronic vaporiser, and the vaporiser has a square or rectangular cross-section and includes a long PCB inserted lengthwise into the vaporiser, in which the electronic vaporiser system includes:
(i) a user-replaceable, e-liquid cartridge, which is not user-refillable and includes no heating element;
(ii) an e-liquid reservoir that is separate from the user-replaceable e-liquid cartridge;
(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
(iv) a 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 the PCB is not mounted at the mid-point of the cross-section, but at a different position closer to a major face of the vaporiser to permit more room for a rechargeable battery.

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

4. The electronic vaporiser system of claim 1 in which the vaporiser includes a narrow pipe to transport e-liquid from the filling end to the reservoir around the heating element and this pipe runs along one internal corner of the vaporiser.

5. The electronic vaporiser system of claim 1 in which the electronic vaporiser system is an e-cigarette system and an e-liquid is a liquid or is a gel.

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

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

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

9. 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.

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

11. 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.

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

13. 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 vaporizer.

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

15. The electronic vaporiser system of claim 14 in which the case includes the electric or electronic pump.

16. 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.

17. The electronic vaporiser system of claim 1 in which the electronic vaporiser includes a structure that is configured to enable excess air-pressure arising from the pressurised e-liquid to escape from the e-liquid reservoir and that is non-porous to the pressurised e-liquid.

18. The electronic vaporiser system of claim 1 wherein the vaporiser has a square or rectangular cross-section with rounded corners.
