Abstract

L'invention concerne un module d'alimentation électrique (100) et un dispositif d'atomisation électronique (300). Le module d'alimentation électrique (100) comprend un support (10) et un élément de protection (17). Une extrémité du support (10) est pourvue d'une colonne d'admission d'air (14) et d'une paroi d'isolation (15), la colonne d'admission d'air (14) étant pourvue d'un trou d'admission d'air (140), la paroi d'isolation (15) étant au moins partiellement disposée autour de la colonne d'admission d'air (14), et un canal d'isolation (16) étant formé entre la paroi d'isolation (15) et la colonne d'admission d'air (14). L'élément de protection (17) est disposé au niveau de l'orifice du trou d'admission d'air (140) faisant face à un atomiseur (200) et bloque l'orifice. La paroi latérale de la colonne d'admission d'air (14), dans laquelle le trou d'admission d'air (140) est formé, est pourvue d'une entrée d'air (141). Étant donné que l'élément de protection (17) bloque l'orifice du trou d'admission d'air (140) faisant face à l'atomiseur (200) et que la paroi latérale du trou d'admission d'air (140) est pourvue de l'entrée d'air (141), le problème de blocage du trou d'admission d'air (140) peut être évité.
