Abstract

L'invention concerne un dispositif de génération d'aérosol. Le dispositif de génération d'aérosol comprend : un corps ; une cartouche structurée pour s'accoupler au corps et formée pour définir une entrée qui est ouverte au niveau d'un côté de la cartouche, le corps pouvant être formé pour définir un trou de détection qui est situé à proximité de l'entrée lorsque la cartouche est accouplée au corps, le positionnement du trou de détection par rapport à l'entrée formant un espace entre le trou de détection et l'entrée qui permet l'introduction d'air dans l'espace ; et un capteur positionné par rapport au trou de détection et conçu pour détecter un écoulement d'air par le trou de détection, le trou de détection pouvant être positionné de façon à chevaucher l'entrée.
