Abstract

Atomiseur (1) et son dispositif d'atomisation électronique (100). L'atomiseur (1) comprend : un boîtier (11), le boîtier (11) étant doté d'une cavité de stockage de liquide (111), d'une cavité de montage (112) et d'un canal de sortie d'air (113) ; un siège de montage (12), qui est au moins partiellement logé dans la cavité de montage (112) ; et un noyau d'atomisation (16) qui est monté à l'intérieur du siège de montage (12), le noyau d'atomisation (16) communiquant avec la cavité de stockage de liquide (111), une surface d'atomisation du noyau d'atomisation (16) étant placée à l'opposé du canal de sortie d'air (113) et espacée de celui-ci, et une cavité d'atomisation (133) étant formée entre le noyau d'atomisation (16) et le canal de sortie d'air (113). Le flux d'air provenant d'une partie d'admission d'air secondaire (127) qui pénètre dans la cavité d'atomisation (133) est utilisé pour souffler une zone de vortex retenue à l'intérieur de la cavité d'atomisation (133), de telle sorte qu'un aérosol dans la zone de vortex pénètre dans le canal de sortie d'air (113) ; simultanément, du gaz qui entre dans la cavité d'atomisation (133) depuis la partie d'admission d'air secondaire (127) forme une couche barrière sur une paroi interne du canal de sortie d'air (113), de telle sorte que le flux d'air transportant l'aérosol n'entre pas en contact avec la paroi interne du canal de sortie d'air (113), empêchant ainsi l'aérosol de venir en contact avec la paroi interne du canal de sortie d'air (113) et de former ainsi un condensat, ce qui augmente la quantité d'atomisation de l'aérosol.
