Abstract

La présente invention se rapporte à un dispositif de génération d'aérosol intelligent équipé d'un mécanisme de verrouillage qui assure la sécurité de l'utilisateur en empêchant un fonctionnement simultané de modes de charge et d'inhalation. Le dispositif comprend un atomiseur, un embout buccal, un composant de batterie et une unité de commande. L'unité de commande est configurée pour détecter la présence d'une alimentation électrique externe et pour désactiver automatiquement une fonctionnalité d'inhalation pendant la charge. Ceci empêche les utilisateurs d'être exposés à des risques électriques associés à des défaillances ou à des fluctuations de puissance. Le dispositif fonctionne selon deux modes : un mode de charge et un mode d'inhalation, déterminés par la présence d'une alimentation électrique d'entrée. L'invention élimine le besoin de dispositifs de verrouillage mécaniques ou d'intervention de l'utilisateur, ce qui fournit une expérience utilisateur sans interruption et sûre. Le dispositif comprend également un processeur qui surveille l'alimentation d'entrée et garantit que l'inhalation n'est possible que lorsque le câble de charge est retiré, ce qui permet d'améliorer les marges de sécurité.
