Abstract

L'invention concerne un atomiseur (10) et un dispositif d'atomisation électronique. L'atomiseur (10) comprend un boîtier (110) ; des entrées d'air (111) et une sortie d'air (112) faisant face à différentes direction, ainsi qu'un canal d'écoulement d'air communiqué entre les entrées d'air (111) et la sortie d'air (112) sont disposés sur le boîtier (110) ; et le canal d'écoulement d'air comprend des canaux d'entrée d'air (113) et une zone d'atomisation (114) en communication l'un avec l'autre, chaque canal d'entrée d'air (113) étant conçu pour s'étendre d'une manière incurvée à partir de l'extrémité proche de l'entrée d'air correspondante (111) jusqu'à l'extrémité proche de la zone d'atomisation (114). L'utilisation de l'atomiseur (10) peut réduire la génération de vortex, de telle sorte qu'une perte d'énergie de flux d'air est faible, un aérosol sur la paroi latérale de la zone d'atomisation (114) peut être retiré dans le processus selon lequel le flux d'air s'écoule de la zone d'atomisation (114) à la sortie d'air (112) et l'aérosol peut être vapoté plus facilement en raison d'une faible résistance à l'écoulement d'air.
