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