Abstract

La présente invention concerne un système de génération d'aérosol. Le système de génération d'aérosol comprend un dispositif de génération d'aérosol comprenant un boîtier et un canal d'écoulement d'air pour distribuer un aérosol. Le canal d'écoulement d'air est disposé à l'intérieur du boîtier. Le système de génération d'aérosol comprend un article de génération d'aérosol. Le système de génération d'aérosol comprend au moins un élément d'arôme. L'élément d'arôme est conçu pour être monté de manière amovible sur le boîtier du dispositif de génération d'aérosol. L'élément d'arôme est conçu pour libérer un arôme. L'élément d'arôme est conçu pour ne pas être en communication fluidique avec le canal d'écoulement d'air lorsque l'élément d'arôme est monté au niveau du boîtier du dispositif de génération d'aérosol, de telle sorte que l'arôme soit libéré de l'élément d'arôme séparément de l'aérosol dans le canal d'écoulement d'air. L'élément d'arôme comprend au moins une source d'arôme. L'élément d'arôme comprend un élément d'accueil. L'élément d'accueil comprend la source d'arôme. L'élément d'accueil comprend au moins une sortie d'arôme. L'élément d'arôme comprend un élément de sélection de libération. L'élément de sélection de libération et l'élément d'accueil comprennent des moyens de fixation complémentaires pour relier de manière amovible l'élément de sélection de libération et l'élément d'accueil.
