Abstract

L'invention concerne un circuit de commande, un boîtier de cigarette, une tige de cigarette, une cigarette électronique et un procédé de commande de cigarette électronique. Le procédé consiste à : recevoir une demande de connexion en provenance d'un second composant d'une cigarette électronique, la demande de connexion transportant des informations d'identification du second composant (S210); lorsque les informations d'identification correspondent pleinement aux informations d'identification prédéfinies, répondre à la demande de connexion, et prendre un premier port de sortie en tant que premier port de communication (S220); acquérir la durée de connexion d'une liaison de communication (S230); lorsque la durée de connexion est plus longue qu'une première durée de communication prédéfinie, générer une première instruction de commutation, la première instruction de commutation étant configurée pour prendre le premier port de sortie en tant que premier port de charge (S240); et exécuter l'instruction de commutation (S250). Lorsqu'une liaison de communication est établie avec succès entre un premier composant et le second composant, le premier composant communique avec le second composant au moyen du premier port de sortie; et, lorsque la durée de communication est plus longue que la première durée de communication prédéfinie, commuter le premier port de sortie pour qu'il serve de port de charge, et charger le second composant par le premier composant au moyen du premier port de sortie, ce qui permet de réduire les ports de connexion entre le premier composant et le second composant, et de simplifier la structure d'une cigarette électronique.
