  • wherein the electronic vaporiser 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 in the system and (ii) returns to seal against its seat at other times when the vaporiser is being vaped or inhaled from, in which the fluid transfer mechanism includes an electric or electronic pump that is configured to withdraw e-liquid from the user-replaceable e-liquid cartridge and pump pressurized e-liquid to the e-liquid reservoir in the vaporiser.
