Abstract

L'invention concerne un atomiseur (1) et un dispositif d'atomisation électronique. L'atomiseur (1) comprend un boîtier (10), une base d'atomisation (30), et un noyau d'atomisation (13) ; le boîtier (10) est pourvu d'un canal de sortie de gaz (15) ; la base d'atomisation (30) est pourvue d'une structure de ventilation (121) et d'une structure de guidage de gaz ; la structure de ventilation (121) amène la structure de guidage de gaz en communication avec l'air extérieur ; le noyau d'atomisation (13) est reçu dans une cavité de réception formée sur la base d'atomisation (30) ; une surface d'atomisation du noyau d'atomisation (13) fait face au canal de sortie de gaz (15) ; la structure de guidage de gaz guide des flux de gaz pour qu'ils s'écoulent vers la surface d'atomisation le long d'au moins trois directions, convergent sur la surface d'atomisation, puis pénètrent dans le canal de sortie de gaz (15). Ainsi, le trajet d'un aérosol atomisé par le noyau d'atomisation (13) entrant dans le canal de sortie de gaz (15) est raccourci au maximum, la génération de courants de Foucault sur la surface d'atomisation est réduite, et l'aérosol résiduel est en outre réduit, ce qui permet de réduire la génération de condensat et d'améliorer la quantité d'aérosol.
