E-CIGARETTE PERSONAL VAPORIZER

1 . A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case includes (a) user-replaceable e-liquid cartridge; and (b) a fluid transfer system adapted to transfer e-liquid from the cartridge to a chamber in the PV; in which the case includes a data processor that controls sending a signal requesting a replacement for a user-replaceable e-liquid cartridge in the case.

2 . The case of claim 1 in which the case or cartridge detects the level of or quantity of e-liquid in the user-replaceable cartridge.

3 . The case of claim 1 in which the signal is sent to a connected smartphone which in turn connects to an e-fulfillment platform.

4 . The case of claim 1 in which the data processor sends a signal to a connected smartphone indicating that a battery used to re-charge the PV in the case needs re-charging.

5 . The case of claim 1 which measures how much e-liquid is left in the user-replaceable cartridge or whether a replacement is needed by using an ultrasonic ranger.

6 . The case of claim 1 which measures how much e-liquid is left in the user-replaceable cartridge or whether a replacement is needed by using a tilt sensor to detect the angle of the cartridge and whether the e-liquid closes an electrical circuit between different electrical contacts at different levels within the cartridge.

7 . The case of claim 1 which measures how much e-liquid is left in the user-replaceable cartridge or whether a replacement is needed by measuring the weight of the cartridge.

8 . The case of claim 1 which measures how much e-liquid is left in the user-replaceable cartridge or whether a replacement is needed by using a capacitive sensor.

9 . The case of claim 1 which measures how much e-liquid is left in the user-replaceable cartridge or whether a replacement is needed by using an air pressure sensor at the top of a flexible tube whose bottom is held just above the bottom of the cartridge.

10 . The case of claim 1 which predicts future levels of e-liquid in the cartridge taking into account the rate of consumption by the user and how much e-liquid is left in the PV itself.

11 . The case of claim 1 which predicts future levels of e-liquid in the cartridge taking into account how much e-liquid is left in the PV itself.

12 . The case of claim 1 which includes a cartridge with several compartments and can fill the PV by combining e-liquid from several compartments and the data processor controls sending a signal requesting a replacement for one or more compartments in the cartridge.

13 . The case of claim 1 which includes several user-removable e-liquid cartridges and can fill the PV by combining e-liquid from several cartridges and the data processor controls sending a signal requesting a replacement for one or more of the cartridges.

14 . The case of claim 1 which gives a visual indication when at least one cartridge level is low or needs replacement.

15 . The case of claim 1 which sends a signal to a connected smartphone indicating that a battery used to re-charge the PV in the case needs re-charging.

16 . The case of claim 1 in which the e-liquid includes nicotine and the PV is not a medicinal device but instead a device that in normal use replaces cigarettes, with the e-liquid being vapourised in the PV and the vapour inhaled to replicate or replace the experience of smoking a cigarette.

17 . Method used in portable, personal storage and carrying case adapted specifically for a refillable e-cigarette PV and that re-fills and re-charges the PV, the method including the steps of the case (a) transferring e-liquid from a user-replaceable e-liquid cartridge to the PV and (b) automatically sending a signal requesting a replacement for the user-replaceable e-liquid cartridge to an e-fulfillment platform, either directly or via a connected smartphone.

18 . The method of claim 17 including the steps of the case (a) detecting the level of or quantity of e-liquid in a user-replaceable e-liquid cartridge in the case and (b) automatically sending a signal requesting a replacement for the user-replaceable e-liquid cartridge to an e-fulfillment platform, either directly or via a connected smartphone.

19 . The method of claim 17 in which the signal is sent to a connected smartphone which in turn connects to an e-fulfillment platform.

20 . The method of claim 17 including the step of a machine learning algorithm or system learning the user's e-liquid consumption patterns and using that to determine when to send the signal requesting the replacement e-liquid cartridge.

21 . The method of claim 17 in which the e-liquid includes nicotine and the PV is not a medicinal device but instead a device that in normal use replaces cigarettes, with the e-liquid being vapourised in the PV and the vapour inhaled to replicate or replace the experience of smoking a cigarette.
