Abstract

L'invention concerne un tube de chauffage, un ensemble d'atomisation et un dispositif d'atomisation électronique. La paroi de tube du tube de chauffage (10) est divisée en une pluralité de sous-parois de tube espacées (11) ; les sous-parois de tube sont pourvues de trous d'ajustement de résistance (110) ; deux sous-parois de tube adjacentes sont reliées l'une à l'autre au moyen d'au moins un pont de connexion électrique (13) ; le pont de connexion électrique (13) est disposé entre deux trous d'ajustement de résistance adjacents (110). Au moyen du procédé, le problème dans l'état de la technique selon lequel un élément chauffant majeur en forme d'arc présente une faible résistance et une petite plage d'application peut être résolu ; pendant ce temps, le tube de chauffage a une structure tubulaire, et a une zone de chauffage plus grande et une résistance structurale supérieure par rapport à un tube de chauffage existant ayant une structure majeure en forme d'arc.
