Abstract

An electronic cigarette vaporiser system operable in a ‘power’ mode to increase the amount of vapour produced by a vaporiser that forms part of the system, compared to normal, whilst monitoring the temperature of a heating element in the vaporiser to ensure that excessively high temperatures, associated with undesirable compounds in the vapour produced by the heating element, are not reached. The system includes a button or sensor that alters the operation of the heating element in such a way as to increase the vapour produced, compared to normal.

Claims

1. An electronic cigarette vaporiser system operable in a ‘

power’

mode to increase the amount of vapour produced by a vaporiser that forms part of the system, compared to normal, whilst monitoring the temperature of a heating element in the vaporiser to ensure that excessively high temperatures, associated with undesirable compounds in the vapour produced by the heating element, are not reached.

2. The electronic vaporiser system of claim 1 in which the system includes a button or sensor that alters the operation of the heating element in such a way as to increase the vapour produced, compared to normal.

3. The electronic vaporiser system of claim 1 in which the button or sensor is on the vaporiser, or a case for the vaporiser, or a connected application running on a connected smartphone or other device.

4. The electronic vaporiser system of claim 1 in which the vaporiser includes no ‘

power mode’

button.

5. The electronic vaporiser system of claim 4 in which the vaporiser includes no other control buttons.

6. The electronic vaporiser system of claim 1 in which activating the ‘

power’

mode involves increasing the PG proportion compared to VG of the e-liquid being vaporised.

7. The electronic vaporiser system of claim 1 in which activating the ‘

power’

mode involves altering the frequency or duty cycle or other operational parameters of a piezo-electric, thermal bubble jet or ultrasonic atomizer, whilst monitoring the temperature of the heating element to ensure it remains at a safe temperature.

8. The electronic vaporiser system of claim 1 including or co-operating 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.

9. The electronic vaporiser system of claim 8 in which the temperature of the heating element is estimated from data stored in the electronics module that has been empirically obtained for a specific heating element design.

10. The electronic vaporiser system of claim 8 in which the electronics module controls the power delivered to the heating element to ensure that it is no higher than approximately 130°

C.

11. The electronic vaporiser system of claim 8 in which the electronics module controls the power delivered using the resistance measurement and does not calculate any derived temperature.

12. The electronic vaporiser system of claim 1 including both a ‘

power’

mode to increase the amount of vapour produced by a vaporiser that forms part of the system, compared to normal, and a ‘

discrete’

mode to decrease the amount of vapour produced by a vaporiser that forms part of the system, compared to normal.

13. The electronic vaporiser system of claim 1, being an e-cigarette system.

14. The electronic vaporiser system of claim 1, being a medicinally approved nicotine drug delivery system.
