Abstract

A electronic cigarette vaporiser that includes a mechanical valve that is (i) pushed up from its seat to enable automatic filling of the vaporiser with e-liquid from a fluid transfer mechanism and (ii) returns to seal against its seat at other times when the vaporiser is being vaped or inhaled from (e.g. when filling is complete).

Claims

1. A electronic cigarette vaporiser that includes a mechanical valve that is (i) pushed up from its seat to enable automatic filling of the vaporiser with e-liquid from a fluid transfer mechanism and (ii) returns to seal against its seat at other times when the vaporiser is being vaped or inhaled from.

2. The electronic vaporiser of claim 1 in which a nozzle or stem from an e-liquid filling device is inserted into the vaporiser for filling the vaporiser with e-liquid and this causes the valve to be pushed open or rise up from its seat, moving against the bias force of a small coil spring or other biasing device, so that e-liquid can freely flow from the e-liquid filling device through the nozzle or stem into a child reservoir in the vaporiser.

3. The electronic vaporiser of claim 2 in which the e-liquid filling device is a re-fill case or removable e-liquid cartridge.

4. The electronic vaporiser of claim 2 in which, when the nozzle or stem is withdrawn, then the valve automatically closes by resting back on its seat.

5. The electronic vaporiser of claim 2 in which a child reservoir in the vaporiser is filled when the valve is open and the fluid transfer mechanism pumps e-liquid into the vaporiser.

6. The electronic vaporiser of claim 5 in which the child reservoir includes a feed pipe that leads into a second child reservoir which surrounds an atomising unit and from which e-liquid is drawn into the atomising unit.

7. The electronic vaporiser of claim 3 in which the stem or nozzle in the re-fill case or cartridge and that engages with the valve in the vaporiser to push it off its seat, passes through a duckbill valve or a series of two or more duckbill valves;

when the vaporiser is withdrawn away from the stem or nozzle then the duckbill wipes any droplets of e-liquid from the stem or nozzle, ensuring that those droplets are not deposited on any surface from where they could be ingested by the user, but are instead retained in a cavity in the vaporiser behind the duckbill valve.

8. The electronic vaporiser of claim 2 in which the stem or nozzle in the e-liquid filling device that is inserted into the vaporiser includes a stop valve to shut off any e-liquid when the vaporiser is withdrawn from the stem or nozzle.

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

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

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

12. The electronic vaporiser of claim 10 which has a square or rectangular cross-section with rounded corners and includes a long PCB inserted lengthwise into the vaporiser.

13. The electronic vaporiser of claim 12 which has a squircle cross-section.

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

15. The electronic vaporiser of claim 14 which 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.

16. The electronic vaporiser of claim 1 which is filled with e-liquid using a piezo-electric pump fluid transfer mechanism.
