Abstract

L'invention concerne une cigarette électronique et un circuit de détection d'huile de tabac. Le circuit de détection d'huile de tabac comprend une unité de déclenchement de combustion (201), un microprocesseur (202), une batterie (203), une unité d'atomisation (204) et un condensateur (205). Le condensateur (205) est disposé à l'intérieur d'une chambre de stockage de liquide (303). Le condensateur (205) est électriquement connecté au microprocesseur (202). Le microprocesseur (202) est utilisé pour pré-stocker une corrélation entre différentes valeurs de capacité du condensateur (205) et différentes quantités d'huile de tabac. Lors de l'acquisition d'une valeur de capacité courante du condensateur (205), le microprocesseur (202) détermine une quantité d'huile de tabac courante correspondant à la valeur de capacité courante en fonction de la corrélation. Le cas d'une combustion sèche de l'unité d'atomisation (204) due à une quantité insuffisante d'huile de tabac est efficacement évité, la génération de gaz nocifs est évitée, et la longévité de l'ensemble atomiseur ainsi que la bonne santé de l'utilisateur sont garanties.
