Abstract

L'invention concerne un noyau d'atomisation ayant une pièce de chauffage microporeuse (2) utilisé pour un atomiseur d'un dispositif d'atomisation électronique. Le noyau d'atomisation comprend un corps de guidage de liquide (1) et une pièce de chauffage (2). Le corps de guidage de liquide (1) est une structure microporeuse solide et peut être utilisé pour absorber, guider et stocker un liquide d'atomisation. Le corps de guidage de liquide (1) est au moins pourvu d'une surface d'atomisation (10) pour chauffer et évaporer le liquide d'atomisation et générer ensuite un aérosol. La pièce de chauffage (2) est disposée sur la surface d'atomisation (10), et une pluralité de micropores pénétrant dans la pièce de chauffage (2) sont formés sur la pièce de chauffage (2). Dans le noyau d'atomisation ayant la pièce de chauffage microporeuse (2), la pièce de chauffage (2) est pourvue de micropores, de telle sorte que l'atomisation est régulière, l'efficacité d'atomisation peut être considérablement améliorée, et étant donné qu'une partie du corps d'ébauche du corps de guidage de liquide (1) peut pénétrer dans la structure microporeuse, deux parties sont plus étroitement et fermement combinées, empêchant ainsi une déformation provoquée par une température élevée pendant le fonctionnement.
