Abstract

La présente invention concerne un dispositif d'atomisation électronique, un ensemble d'alimentation électrique et un cadre de support associé. Un réservoir de stockage de liquide et une colonne d'entrée d'air sont disposés à une extrémité du cadre de support ; la colonne d'entrée d'air est pourvue d'un trou d'air ; le trou d'air est en communication fluidique avec le réservoir de stockage de liquide ; et la colonne d'entrée d'air est pourvue d'une structure de drainage autour du trou d'air, la structure de drainage étant utilisée pour drainer le liquide vers le réservoir de stockage de liquide. La structure de drainage est disposée à l'extrémité de la colonne d'entrée d'air, de telle sorte que le liquide accumulé à l'extrémité de la colonne d'entrée d'air est guidé vers le réservoir de stockage de liquide. Le cadre de support fourni par la présente invention peut réduire efficacement le risque de blocage du trou d'air par le liquide.
