Abstract

Selon un mode de réalisation, le dispositif de génération d'aérosol selon l'invention comprend : un corps principal ; et une cartouche accouplée amovible au corps principal. La cartouche comprend : un réservoir pour stocker une matière de génération d'aérosol ; une structure chauffante pour chauffer la matière de génération d'aérosol ; et une mèche pour fournir la matière de génération d'aérosol stockée dans le réservoir à la structure chauffante. Le corps principal comprend : un circuit de détection de cartouche pour détecter la température de la structure chauffante de la cartouche, un condensateur n'étant pas connecté à une borne de sortie du circuit de détection de cartouche ; et un processeur connecté électriquement au circuit de détection de cartouche. Le processeur peut détecter la température de la structure chauffante par l'intermédiaire du circuit de détection de cartouche, et commander l'alimentation en énergie de la cartouche sur la base de la température détectée de la structure chauffante.
