Abstract

L'invention concerne un appareil et des procédés associés concernant l'adaptation d'un réservoir de stockage de fluide compressible avec des aimants conçus pour comprimer un fluide retenu à l'intérieur du réservoir, la configuration d'un transducteur pour vaporiser un fluide dans une chambre de vaporisation de fluide en communication fluidique avec le réservoir de stockage de fluide, et la génération automatique d'une vapeur en alimentant le transducteur et en transférant le fluide du réservoir de stockage de fluide dans la chambre de vaporisation de fluide lorsqu'un vide est appliqué à un embout en communication fluidique avec la chambre de vaporisation de fluide. Dans un exemple illustratif, le fluide peut contenir de la nicotine. Dans divers modes de réalisation, le transducteur peut être ultrasonore, permettant une vaporisation de fluide sûre sur la base d'une agitation ultrasonore. Dans certains modes de réalisation, le transducteur peut être alimenté au moyen d'un condensateur chargé. Dans certains modes de réalisation, le réservoir de stockage de fluide peut être un boîtier remplaçable ayant un joint étanche anti-fuites pouvant être perforé par aiguille pour permettre un transfert de fluide vers la chambre de vaporisation. Divers exemples peuvent avantageusement réduire l'exposition de l'utilisateur à divers dangers.
