Abstract

La présente invention a trait au domaine des dispositifs d'atomisation. L'invention concerne un atomiseur, un dispositif d'atomisation et un procédé de commande d'un atomiseur. L'atomiseur comprend un second élément chauffant permettant de chauffer un substrat de formation d'aérosol. Le dispositif d'atomisation comprend l'atomiseur et une alimentation électrique connectée électriquement à un premier élément chauffant et au second élément chauffant de l'atomiseur. Le procédé de commande comprend les étapes suivantes : a) l'activation d'un second élément chauffant afin de chauffer un substrat de formation d'aérosol dans une cavité de récipient de liquide à une première puissance de chauffage, de sorte que le substrat de formation d'aérosol est absorbé par un élément de distribution de liquide ; b) et l'activation d'un premier élément chauffant afin d'atomiser le substrat de formation d'aérosol absorbé par l'élément de distribution de liquide. La présente invention utilise un second élément chauffant indépendant d'un élément d'atomisation afin de chauffer un substrat de formation d'aérosol dans une cavité de récipient de liquide, de sorte que le substrat de formation d'aérosol a une température élevée, une viscosité réduite et une aptitude à l'écoulement accrue de façon à être absorbé rapidement par un élément de distribution de liquide, ce qui empêche l'endommagement de l'élément d'atomisation résultant d'une combustion à sec.
