Abstract

L'invention concerne une cigarette électronique et un procédé d'ajustement du débit d'un écoulement de gaz de la cigarette électronique. La cigarette électronique comprend une tige de cigarette (100) munie d'une pile, un support de cigarette (104), d'un vaporisateur (300) rempli d'une fumée liquide et utilisé pour vaporiser la fumée liquide, et d'un passage d'écoulement de gaz pour l'écoulement du gaz vers le vaporisateur (300). Un ensemble valve de régulation de la pression (400) est agencé sur un trajet du passage d'écoulement du gaz. L'ensemble valve de régulation de la pression (400) comprend une sphère flottante qui est utilisée pour fermer et ouvrir le passage d'écoulement du gaz en fonction de la direction d'écoulement du gaz et réguler le débit d'écoulement du gaz dans le passage d'écoulement du gaz. Le débit de l'air extérieur entrant dans le vaporisateur (300) est régulé par l'ensemble valve de régulation de la pression (400), et la quantité de fumée inhalée par la personne est régulée, ce qui permet de modifier le goût de la fumée, et de satisfaire les demandes de différents utilisateurs ; en outre lorsqu'un utilisateur souffle de l'air dans la cigarette électronique, comme l'ensemble valve de régulation de la pression (400) est fermé, l'écoulement la fumée liquide du vaporisateur (300) dans la pile et un panneau de commande peut être empêché, ce qui prolonge la durée de fonctionnement de la cigarette électronique.
