Abstract

L'invention concerne une bombe aérosol (800). La bombe aérosol (800) n'est pas pourvue d'une partie centrale d'atomisation. La bombe aérosol (800) comprend un élément de stockage de liquide (100), un élément d'échange gaz-liquide (290) pour bloquer une ouverture au fond de l'élément de stockage de liquide (100), et un canal d'aérosol (1303) pénétrant axialement dans l'élément de stockage de liquide (100). La bombe aérosol (800) ne comprend pas la partie centrale d'atomisation, la bombe aérosol (800) est remplacée après épuisement d'un liquide, et la partie centrale d'atomisation peut être utilisée de manière répétée. Par conséquent, les coûts sont considérablement réduits, et le gaspillage de ressources est également réduit.
