L'invention concerne un dispositif d'atomisation électronique (100) comprenant : un couvercle supérieur chauffant (20) comprenant un corps de couvercle (23) et une paroi de guidage d'écoulement (24) disposée sur le corps de couvercle (23), la paroi de guidage d'écoulement (24) étant disposée de manière annulaire pour former une cavité d'atomisation (25), le corps de couvercle (23) étant pourvu d'une sortie d'aérosol (21), la sortie d'aérosol (21) étant en communication avec la cavité d'atomisation (25), la paroi de guidage d'écoulement (24) étant pourvue d'une entrée d'air (26), et l'entrée d'air (26) étant en communication avec la cavité d'atomisation (25) ; et un noyau d'atomisation (30) relié au couvercle supérieur chauffant (20), un premier orifice (261) de l'entrée d'air (26) étant en communication avec la cavité d'atomisation (25), un second orifice (211) de la sortie d'aérosol (21) étant en communication avec la cavité d'atomisation (25), et le premier orifice (261) et le second orifice (211) étant respectivement situés sur deux côtés opposés du noyau d'atomisation (30), de telle sorte que l'écoulement d'air transporte plus complètement l'aérosol généré sur une surface d'atomisation (32) pour qu'il s'écoule vers la sortie d'aérosol (21), de façon à empêcher l'aérosol d'être retenu dans la cavité d'atomisation (25), ce qui permet d'augmenter efficacement le rendement d'aérosol et d'améliorer l'efficacité d'atomisation.
