Abstract
An electronic vapor provision system includes a control unit and a cartridge configured to engage with and disengage from one another substantially along a longitudinal axis. The cartridge includes a reservoir of liquid to be vaporized, and the control unit includes a battery and a tube portion disposed along said longitudinal axis. The system further includes an induction heating assembly comprising a drive coil and a heater element. The heater element is located in the cartridge for vaporizing the liquid. The cartridge is configured to feed liquid from the reservoir onto the heater element for vaporization. The drive coil is located in the tube portion of the control unit and disposed about the longitudinal axis. The cartridge is located at least partly within the tube portion when engaged with the control unit, such that the heater element is within the drive coil.
