Le noyau d'atomisation est utilisé pour un atomiseur d'un appareil d'atomisation électronique, et le noyau d'atomisation comprend un corps de guidage de liquide et un corps chauffant. Le corps de guidage de liquide comprend une surface d'absorption de liquide et une surface d'atomisation ; le corps chauffant est disposé sur la surface d'atomisation du corps de guidage de liquide ; et le corps de guidage de liquide est pourvu d'une pluralité de micropores directionnels qui communiquent directement avec la surface d'atomisation depuis la surface d'absorption de liquide. Le noyau d'atomisation présente les effets bénéfiques suivants : les composants d'un liquide d'atomisation ne provoquent pas de blocage dans les micropores directionnels, de telle sorte que la quantité d'atomisation puisse être augmentée, que le degré de réduction d'un aérosol puisse être augmenté, et qu'une odeur de brûlé ne soit pas facilement générée lors d'une température élevée ; et le corps de guidage de liquide est constitué d'un silicium monocristallin et d'un matériau de verre, ce qui permet d'obtenir une pureté élevée avec peu d'impuretés, et de ne pas précipiter les composants, tels qu'un métal lourd, qui sont nocifs pour la santé.
