Abstract

La présente invention concerne un dispositif d'atomisation électronique, un atomiseur et un ensemble de stockage de liquide associé. L'ensemble de stockage de liquide est pourvu d'une cavité de pression d'air, d'une cavité de stockage de liquide, d'un trou d'air et d'un trou de liquide. La cavité de pression d'air est isolée de la cavité de stockage de liquide, le trou d'air communique avec la cavité de pression d'air, et le trou de liquide communique avec la cavité de stockage de liquide. Du gaz est injecté dans la cavité de pression d'air au moyen du trou d'air de façon à comprimer la cavité de stockage de liquide, de telle sorte que le liquide stocké dans la cavité de stockage de liquide s'écoule vers l'extérieur par l'intermédiaire du trou de liquide. Ainsi, selon l'ensemble de stockage de liquide fourni par la présente invention, des phases de stockage et d'utilisation d'un substrat de génération d'aérosol peuvent être séparées, ce qui permet d'empêcher qu'une quantité excessive de liquide s'accumule au niveau d'un ensemble d'atomisation, réduisant efficacement le risque de fuite de liquide, et peuvent empêcher une dégradation de la sensation en bouche provoquée par la macération prolongée de l'ensemble d'atomisation et du substrat de génération d'aérosol.
