The dynamic diffuser for a naturally diffusing liquid substance such as a perfume comprises a receptacle (14) for said substance (12) and having a vertical flank which is closed by a membrane (16) that is impermeable to liquid but permeable to gas. All or part of the membrane (16) is caused to come into contact with said substance (12), at least intermittently, by revolving the receptacle about a horizontal axis (D). Air-flow generating means, e.g. impeller blades (6), serve to cause air to flow over the outside of the membrane (16).

Le diffuseur dynamique pour une substance liquide naturellement diffusante, tel un parfum, comprend un récipient (14) pour ladite substance (12) avec un flanc vertical fermé par une membrane (16) qui est imperméable au liquide mais perméable au gaz. La membrane (16) est amenée en tout ou en partie à entrer en contact avec ladite substance (12), au moins de façon intermittente, quand on fait tourner le récipient autour d'un axe horizontal (D). Un moyen pour générer un flux d'air, par exemple une roue à aubage (6), sert à faire circuler de l'air sur l'extérieur de la membrane (16).
