Abstract

L'invention concerne un dispositif de détection d'un excédent d'huile de tabac d'une cigarette électronique, la cigarette électronique et un procédé de commande de cigarette électronique, qui permettent de résoudre les problèmes techniques rencontrés dans l'état de la technique selon lesquels une cigarette électronique ne permet pas à un utilisateur de savoir qu'il y a un excédent d'huile de tabac et le coton est brûlé si la cigarette électronique continue à être fumée lorsque la quantité d'huile de tabac est réduite ou que l'huile de tabac est consommée. Le dispositif de détection comprend : un capteur d'huile de tabac (10) dans une chambre de stockage d'huile d'une cigarette électronique, utilisé pour détecter le niveau liquide d'huile de tabac dans une chambre de stockage d'huile (212) lorsqu'une tige de tabac est perpendiculaire au plan horizontal, de manière à produire un signal de détection ; et un microprocesseur (20) connecté au capteur d'huile de tabac (10), utilisé pour commander la mise en marche ou l'arrêt d'un circuit d'atomisation de la cigarette électronique en fonction du signal de détection et/ou utilisé pour traiter le signal de détection pour obtenir et délivrer en sortie un signal d'indication d'excédent d'huile de tabac, de manière à permettre à un utilisateur de reconnaître un excédent d'huile de tabac en cours de la cigarette électronique. Les effets techniques obtenus sont les suivants : lorsqu'un utilisateur utilise une cigarette électronique, un excédent d'huile de tabac est détecté et l'utilisateur est notifié de l'excédent d'huile de tabac, puis la cigarette électronique est commandée pour commencer à fonctionner lorsque l'excédent d'huile de tabac suffit ; et la cigarette électronique est commandée pour s'arrêter de fonctionner quand l'excédent d'huile de tabac a fortement diminué, de manière à éviter de brûler le coton.
