Abstract

L'invention concerne un dispositif de génération d'aérosol muni d'un capteur qui détecte une aspiration par un utilisateur, un premier élément de chauffage qui chauffe une première source d'aérosol, un second élément de chauffage qui chauffe une seconde source d'aérosol et un élément de commande qui commande l'alimentation en énergie du premier élément de chauffage et du second élément de chauffage. Lors de l'exécution d'une action destinée à générer un aérosol par combinaison du chauffage de la première source d'aérosol et du chauffage de la seconde source d'aérosol, l'élément de commande arrête ou réduit l'alimentation en énergie du second élément de commande de chauffage lorsque le temps écoulé depuis la fin de l'aspiration détectée en dernier par le capteur dépasse un seuil prédéterminé.
