Title
(EN) ELECTRONIC VAPOUR PROVISION SYSTEM
(FR) SYSTÈME DE FOURNITURE DE VAPEUR ÉLECTRONIQUE
Abstract
(EN) Various embodiments of the invention provide an electronic vapour provision system (610) having a longitudinal axis. The electronic vapour provision system comprises a control unit (620) and at least one cartridge (630) configured to engage with and disengage from the control unit substantially along said longitudinal axis. The at least one cartridge includes a reservoir (670) of liquid to be vaporised. The electronic vapour provision system further comprises an induction heating assembly comprising at least one drive coil (650) and a plurality of heater elements (655A, 655B). The heater elements are located in the at least one cartridge for vaporising said liquid. The at least one cartridge is configured to feed liquid from the reservoir onto the heater elements for vaporisation. 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 vapour provision system is configured to support selective energisation of different heater elements from the plurality of heater elements.
(FR) Divers modes de réalisation de l'invention concernent un système de fourniture de vapeur électronique présentant un axe longitudinal. Le système de fourniture de vapeur électronique comprend une unité de commande et au moins une cartouche conçue pour s'engager sur l'unité de commande et se libérer de celle-ci sensiblement le long dudit axe longitudinal. Ladite au moins une cartouche comprend un réservoir de liquide à vaporiser. Le système de fourniture de vapeur électronique comprend en outre un ensemble de chauffe par induction comprenant au moins une bobine d'excitation et une pluralité d'éléments chauffants. Les éléments chauffants sont situés dans ladite au moins une cartouche pour la vaporisation dudit liquide. Ladite au moins une cartouche est conçue pour amener le liquide du réservoir sur les éléments chauffants en vue de sa vaporisation. Lorsqu'elle est engagée sur l'unité de commande, ladite au moins une cartouche est située de telle sorte que les éléments chauffants se trouvent à l'intérieur de ladite au moins une bobine d'excitation. Le système de founiture de vapeur électronique est conçu pour permettre l'excitation sélective de différents éléments chauffants parmi la pluralité d'éléments chauffants.
