1. An electronic cigarette vaporiser system that includes an electronic vaporiser, wherein the electronic vaporiser includes a heating element and further includes 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;

  • in which the electronic vaporiser system includes (i) a user-replaceable, e-liquid cartridge that is attached to or integral with the system whilst the system is being vaped by an end-user, 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

    in which (iv) the heating element is not in the user-replaceable e-liquid cartridge but is instead in, or in e-liquid communication with, the e-liquid reservoir.
