Abstract

L'invention concerne une cigarette électronique et un procédé de commande d'atomisation associé. La cigarette comprend un atomiseur (1) et un ensemble tige-batterie (2), l'ensemble tige-batterie (2) étant doté d'une batterie (21) qui fournit de l'énergie à l'atomiseur (1) de manière à atomiser de l'huile de cigarette; la cigarette électronique comprend en outre une unité de commande (3) électriquement connectée à l'atomiseur (1) et à la batterie (21); l'atomiseur (1) comprend un ensemble réservoir d'huile, une buse d'aspiration (11) et un noyau d'atomisation permettant d'atomiser l'huile de cigarette, l'ensemble réservoir d'huile étant doté d'une chambre de stockage d'huile (101) et d'un orifice d'alimentation en huile (102), une extrémité du noyau d'atomisation étant gainée par un tube flexible étanche (13) qui est en communication avec un passage de fumée et la buse d'aspiration (11), et un élément conducteur (14) étant gainé à l'extérieur du tube flexible étanche (13); la buse d'aspiration (11) est introduite dans l'ensemble réservoir d'huile et vient buter contre l'élément conducteur (14) de manière à être électriquement connectée à l'unité de commande (3) ou à la batterie (21) par l'intermédiaire de l'élément conducteur (14), et un manchon conducteur (22) est gainé sur une surface périphérique externe de l'ensemble tige-batterie (2); et un élément, soit la buse d'aspiration (11) soit le manchon conducteur (22), est électriquement connecté à l'unité de commande (3), et l'autre élément est électriquement connecté à la batterie (21). Lorsqu'un utilisateur fume, la peau entre en contact avec la buse d'aspiration (11) et le manchon conducteur (22) pour permettre à la buse d'aspiration (11) d'être en conduction avec le manchon conducteur (22), et lorsque l'unité de commande (3) détecte que la buse d'aspiration (11) est en conduction avec le manchon conducteur (22), la batterie (21) est commandée pour fournir de l'énergie à l'atomiseur (1) de manière à atomiser l'huile de cigarette.
