Abstract

La présente invention concerne une cigarette électronique (100) comprenant : un premier logement (10), où un tube (30) de cartouche de cigarettes et un atomiseur (40) sont logés à l'intérieur du premier logement (10), la cartouche de cigarettes (20) comprend un support de tube (22) de cartouche de cigarettes permettant de stocker un e-liquide et un élément d'étanchéité (26) scellé à une extrémité du support de tube (22) de cartouche de cigarettes faisant face à l'atomiseur (40), l'atomiseur (40) comprend un composant chauffant (44), un élément de perforation (48) et une base de fixation (42) d'atomiseur supportant le composant chauffant (44) et l'élément de perforation (48) ; et, un second logement (62) relié par filetage avec le premier logement (10), où une partie d'éjecteur (68) est fixée à l'intérieur du second logement (62), la partie éjecteur (68) pouvant pousser la base de fixation (42) de l'atomiseur lorsque le premier logement (10) et le second logement (62) sont reliés par filetage de sorte que l'élément de perforation (48) perfore l'élément d'étanchéité (26) du tube (20) de cartouche de cigarettes, ce qui permet de retirer l'e-liquide. En raison du fait que l'e-liquide est injecté dans le tube (20) de cartouche de cigarettes pendant la production et est fermé de manière étanche à l'aide de l'élément d'étanchéité (26), lors de l'utilisation, l'e-liquide est autorisé à pénétrer dans le composant chauffant (44) simplement en ayant l'élément de perforation (48) perforant l'élément d'étanchéité (26), à ce titre, le problème classique de stockage ou de mise en place incorrecte de l'e-liquide est éliminé, et l'e-liquide n'est pas sujet à la contamination.
