Abstract

La présente invention concerne un atomiseur, une cigarette électronique et un dispositif de stockage de liquide remplaçable. L'atomiseur comprend un dispositif de stockage de liquide (100) et un ensemble d'atomisation (200), l'ensemble d'atomisation comprenant une chambre d'atomisation et une unité d'atomisation disposée dans la chambre d'atomisation; l'ensemble d'atomisation comprenant une partie de raccordement (202) permettant le raccordement au dispositif de stockage de liquide, une admission de liquide (203) en communication avec la chambre d'atomisation est disposée sur la partie de raccordement, un joint (109) comprenant une évacuation de liquide (110) est disposé sur une extrémité ouverte du dispositif de stockage de liquide, et la partie de raccordement est adaptée pour être insérée dans l'extrémité ouverte du dispositif de stockage de liquide puis tournée d'un angle prédéfini de manière à former un raccordement d'entrée en prise avec le dispositif de stockage de liquide. Lorsque la partie de raccordement forme un raccordement d'entrée en prise avec le dispositif de stockage de liquide, l'évacuation de liquide et l'admission de liquide sont reliées. Lorsque la partie de raccordement est en train d'être séparée du dispositif de stockage de liquide, la partie de raccordement peut entraîner l'élément rotatif pour bloquer l'évacuation de liquide. Dans des exemples d'une cigarette électronique utilisant l'atomiseur, le risque que le liquide à vapoter ne se renverse depuis le dispositif de stockage de liquide dans n'importe quel état peut être réduit ou éliminé, de manière à garantir au consommateur une expérience utilisateur satisfaisante.
