Abstract

La présente invention concerne un dispositif de génération d'aérosol comprenant un réservoir de liquide primaire, un réservoir de liquide secondaire et un embout buccal agencés séquentiellement les uns après les autres. Le réservoir de liquide primaire comprend un liquide aérosolisable qui est transportable vers le réservoir de liquide secondaire à travers au moins une ouverture, créant ainsi un trajet d'écoulement de liquide. Le dispositif de génération d'aérosol comprend en outre au moins une unité de génération d'aérosol disposée dans le trajet d'écoulement de liquide pour générer un aérosol inhalable qui s'écoule vers l'embout buccal, créant ainsi un trajet d'écoulement d'aérosol. Le réservoir de liquide primaire comprend en outre un volume variable entouré par une paroi périphérique au moins en partie non rigide qui est mécaniquement déformable et/ou extensible. Le liquide aérosolisable est extractible et/ou rechargeable du réservoir de liquide primaire à travers l'ouverture vers l'unité de génération d'aérosol pendant la pressurisation du réservoir de liquide primaire. Le liquide aérosolisable occupe tout le volume du réservoir de liquide primaire et/ou le réservoir de liquide primaire est scellé de manière étanche aux gaz.
