Abstract

L'invention concerne une boîte à cigarette électronique (100) et un procédé de charge d'une cigarette électronique. La boîte à cigarette électronique (100) comprend un corps de boîte à cigarette pour accueillir une cigarette électronique. Un port de charge est disposé sur le corps de boîte à cigarette. La cigarette électronique est insérée dans le port de charge pendant la charge. La boîte à cigarette électronique (100) comprend également un contrôleur (110) et comprend un commutateur de déclenchement (120), un module de détection de charge (130) et un module de délivrance de charge de cigarette électronique (140), tous reliés au contrôleur (110). Le commutateur de déclenchement (120) est proche du port de charge, et lorsque la cigarette électronique est insérée dans le port de charge, le commutateur de déclenchement (120) est déclenché. Lorsqu'il détecte que le commutateur de déclenchement (120) est déclenché, le contrôleur (110) commande le module de délivrance de charge de cigarette électronique (140) pour passer dans un mode de charge. Dans le mode de charge, le module de délivrance de charge de cigarette électronique (140) génère un courant de charge et délivre le courant de charge à la cigarette électronique de manière à charger la cigarette électronique insérée. Lorsque le module de détection de charge (130) détecte que la cigarette électronique est entièrement chargée, le contrôleur (110) commande le module de délivrance de charge de cigarette électronique (140) pour passer dans un mode veille ultra-faible. Dans le mode de veille ultra-faible, le module de délivrance de charge de cigarette électronique (140) cesse de générer le courant de charge, de sorte qu'un courant de veille de la boîte à cigarette électronique (100) est inférieur à 10 microampères.
