Abstract

L'inhalateur d'arôme de type sans combustion de l'invention comprend : une partie de stockage de liquide qui stocke un liquide de génération d'aérosol ; une partie d'atomisation qui atomise le liquide de génération d'aérosol ; une capsule d'arôme qui contient une source d'arôme ; un boîtier qui comporte une partie de logement logeant la capsule d'arôme de sorte que l'aérosol résultant de l'atomisation par la partie d'atomisation traverse l'intérieur de la capsule d'arôme ; un capteur capacitif qui détecte une capacité qui varie en fonction de l'état de la capsule d'arôme logée dans la partie de logement ; et une partie de commande qui, lorsque la capacité de la capsule d'arôme détectée par le capteur capacitif a dépassé une valeur seuil prescrite, détermine l'état d'achèvement de l'utilisation de la capsule d'arôme et effectue une commande qui accompagne l'achèvement de l'utilisation. Ainsi, l'invention concerne une technologie qui détermine de manière appropriée une condition d'achèvement d'utilisation.
