L'atomiseur (100) comprend : une coque (10) pourvue d'une cavité de stockage de liquide (13), la cavité de stockage de liquide (13) comprenant une première partie (131) et une seconde partie (132), qui sont réparties longitudinalement et la première partie (131) étant creuse, de façon à fournir un espace pour stocker un substrat liquide ; un élément de stockage de liquide (16) rempli dans la seconde partie (132), l'élément de stockage de liquide (16) étant conçu pour absorber et stocker une partie du substrat liquide à partir de la première partie (131) ; un premier élément de guidage de liquide (15) espaçant la première (131) et la seconde partie (132), le premier élément de guidage de liquide (15) étant en contact avec l'élément de stockage de liquide (16) et le premier élément de guidage de liquide (15) étant conçu pour être perméable aux liquides, de façon à transférer le substrat liquide dans la première partie (131) à l'élément de stockage de liquide (16) ; et un ensemble d'atomisation (17), qui est utilisé pour atomiser le substrat liquide à partir de l'élément de stockage de liquide (16) de façon à générer un aérosol. Le taux d'utilisation d'espace de la cavité de stockage de liquide (13) de l'atomiseur (100) peut être efficacement augmenté, de telle sorte que plus de substrats liquides peuvent être contenus dans la cavité de stockage de liquide (13).
