Abstract

Un appareil d'atomisation électronique et un atomiseur associé sont divulgués dans la présente invention. L'atomiseur comprend une structure de récupération de condensat, et la structure de récupération de condensat est disposée sur une base d'atomisation. La structure de récupération de condensat comprend une première partie de communication et une partie de guidage d'écoulement. La partie de guidage d'écoulement est reliée à un canal de sortie d'air et à la première partie de communication. La première partie de communication est en communication avec une matrice poreuse. Lorsque l'aérosol est condensé dans le canal de sortie d'air pour former le condensat, le condensat peut être guidé vers la première partie de communication au moyen de la partie de guidage d'écoulement, de façon à être en contact avec la matrice poreuse. Les micropores de la matrice poreuse peuvent absorber le liquide. Pendant une opération d'aspiration, le condensat est atomisé une seconde fois au moyen de la matrice poreuse, de façon à réduire les résidus du condensat dans l'atomiseur.
