Abstract

L'invention concerne un atomiseur (100), un appareil d'atomisation électronique et un ensemble atomisation. L'atomiseur (100) comprend : une cavité de stockage de liquide (12) ; des éléments de guidage de liquide (31, 32), comprenant une première surface et une seconde surface opposées l'une à l'autre et la première surface étant utilisée pour aspirer une matrice liquide à partir de la cavité de stockage de liquide (12) ; et un élément chauffant (40), comprenant une partie de chauffage étendue sensiblement plane (43). La partie de chauffage (43) est utilisée pour chauffer au moins une partie de la matrice liquide dans les éléments de guidage de liquide (31, 32) pour générer un aérosol. La partie de chauffage (43) est située entre la première et la seconde surface. De plus, la partie de chauffage (43) comprend un premier côté proche de la première surface et un second côté opposé au premier. Les éléments de guidage de liquide (31, 32) sont conçus pour entourer ou recouvrir le second côté de la partie de chauffage (43) et exposer au moins partiellement le premier côté de la partie de chauffage (43). L'atomiseur (100) agence l'élément chauffant (40) dans les éléments de guidage de liquide (31, 32) et amène les éléments de guidage de liquide (31, 32) à fournir la matrice liquide au second côté de la partie de chauffage (43) et à libérer l'aérosol généré à partir du premier côté de la partie de chauffage.
