Title
(EN) ELECTRONIC VAPOUR PROVISION SYSTEM
Abstract
(EN)

Embodiments of an electronic vapor provision system having a longitudinal axis are disclosed. The electronic vapor provision system includes a control unit and at least one cartridge configured to engage with and disengage from the control unit substantially along the longitudinal axis. The at least one cartridge includes a reservoir of liquid to be vaporized. The electronic vapor provision system further includes an induction heating assembly including at least one drive coil and a plurality of heater elements. The heaters elements are located in the at least one cartridge for vaporizing the liquid. The at least one cartridge is configured to feed liquid from the reservoir onto the heater elements for vaporization. The at least one cartridge is located, when engaged with the control unit, such that the heater elements are within the at least one drive coil. The electronic vapor provision system is configured to support selective energization of different heater elements from the plurality of heater elements.
