Le dispositif d'inhalation (100) chauffe une source d'aérosol afin de générer un aérosol. La partie de réception d'alimentation électrique (200) présente une ouverture (201) dans laquelle l'unité d'alimentation électrique (111) peut être insérée et de laquelle elle peut être retirée. L'unité d'alimentation électrique (111) est montée de manière amovible sur la partie de réception d'alimentation électrique (200). Le dispositif d'inhalation (100) comprend en outre un panneau (30) qui ouvre et ferme l'ouverture (201) de la partie de réception d'alimentation électrique (200), et un capteur de détection ouvert/fermé (20d) qui détecte l'état ouvert/fermé de l'ouverture (201) provoquée par le panneau (30). L'unité de commande (116) commande l'unité d'alimentation électrique (111) sur la base du résultat de détection provenant du capteur de détection ouvert/fermé (20d).
