Abstract

An electronic cigarette vaporizer includes a heating element, an air pressure sensor and a microcontroller; the microcontroller stores, processes or determines the extent of each inhalation using signals from the air pressure sensor. The microcontroller can calculate the approximate e-liquid consumption from the extent of each inhalation or provide data that enables an external processor to calculate approximate e-liquid consumption. The extent of an inhalation is a function of one or more of: duration; peak flow rate; average flow rate.

First claim

The invention claimed is:

1. An electronic cigarette vaporiser system that includes an electronic vaporiser, wherein the electronic vaporiser includes a heating element, an air pressure sensor and a microcontroller; in which the microcontroller stores, processes or determines the extent of each inhalation using signals from the air pressure sensor; in which the electronic vaporiser system includes (i) a user-replaceable, e-liquid cartridge that is attached to or integral with at least a part of the system, 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 (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 the microcontroller calculates the approximate e-liquid consumption from the extent of each inhalation or provides data that enables an external processor to calculate approximate e-liquid consumption.

3. The electronic vaporiser system of claim 1 in which the microcontroller calculates when and if the heating element needs to be cleaned or replaced based on the number and/or extent of the inhalations made, or provides data that enables an external processor to make this calculation.

4. The electronic vaporiser system of claim 2 in which the microcontroller calculates the approximate quantity of e-liquid left in the vaporiser based on the calculated approximate e-liquid consumption.

5. The electronic vaporiser system of claim 2 in which the microcontroller calculates the approximate quantity of e-liquid left in the vaporiser based on the calculated approximate e-liquid consumption and also using data from other elements in the vaporiser or a case that re-fills the vaporiser.

6. The electronic vaporiser system of claim 1 in which the extent of an inhalation is a function of one or more of: duration; peak flow rate; average flow rate.

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 cigarette and 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 has a square or rectangular cross-section with rounded corners and includes a long PCB inserted lengthwise into the vaporiser.

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

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

13. 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.

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 vaporizer system of claim 1 , further comprising a structure that is configured to enable excess air-pressure arising from the pressured e-liquid to escape from the e-liquid reservoir and that is non-porous to the pressurized e-liquid.

18. The electronic vaporiser system of claim 1 , in which the pump is in a desktop station.
