Abstract

La présente divulgation concerne un ensemble atomisation d'une cigarette électronique, ainsi qu'une cigarette électronique. L'ensemble atomisation d'une cigarette électronique comprend un logement, une cavité de stockage de liquide située dans le logement, une base inférieure, un couvercle supérieur et un ensemble noyau d'atomisation. Le logement est pourvu d'un canal de sortie d'air. La base inférieure est reliée au boîtier de manière correspondante et est pourvue d'un canal d'admission d'air. Le couvercle supérieur est situé dans le logement et comprend un corps de couvercle supérieur ainsi qu'un couvercle de tête situé au sommet du corps de couvercle supérieur. Le corps de couvercle supérieur est pourvu d'un canal d'écoulement d'air. Le couvercle de tête est pourvu d'une encoche qui est disposée dans une direction faisant face à une paroi interne du logement et forme une sortie d'air avec la paroi interne du logement au moyen d'une enceinte. Le canal de sortie d'air est en communication avec la sortie d'air. L'ensemble noyau d'atomisation est situé dans le logement, est disposé entre le corps de couvercle supérieur et la base inférieure et a une surface d'atomisation faisant face à la base inférieure. Une cavité d'atomisation est formée entre la surface d'atomisation et la base inférieure. La cavité d'atomisation est en communication avec la sortie d'air au moyen du canal d'écoulement d'air et est en communication avec le canal d'admission d'air.
