Abstract

La présente invention concerne un noyau d'atomisation (3) et un atomiseur réduisant la pression de refoulement, ainsi qu'une cigarette électronique. Le noyau d'atomisation (3) comprend un corps de noyau d'atomisation. Un passage de gaz permettant le passage d'un écoulement de gaz est formé dans le corps de noyau d'atomisation, une paroi du corps de noyau d'atomisation est pourvue d'un trou de gaz (306), le trou de gaz (306) étant en communication avec le passage de gaz, et une paroi externe du corps de noyau d'atomisation est pourvue d'une rainure (305), la rainure (305) étant en communication avec le trou de gaz (306). La rainure (305) est conçue sous la forme d'une fente à travers laquelle seul un gaz peut passer et/ou le trou d'air (306) est conçu sous la forme d'un trou à travers lequel seul un gaz peut passer. Dans le noyau d'atomisation (3) et l'atomiseur réduisant la pression de refoulement, et la cigarette électronique, au moyen de la conception d'un passage de réduction de pression, l'équilibre de pression d'air dans une cavité de stockage de liquide (103) peut être maintenu par ajout d'air en utilisant le trou d'air (306) et le passage de réduction de pression, de telle sorte que le liquide est alimenté plus rapidement, et l'arrêt par épuisement d'un élément chauffant en raison d'une admission de liquide lente et d'une alimentation en liquide insuffisante est résolu.
