| 摘要 |
The invention relates to a device for the diffusion of volatile substances, comprising means for generating a current of air, characterised in that said air current generating means comprise a flexible sheet (1) and at least one piezoelectric element (2), such that said piezoelectric element (2) causes the flexible sheet (1) to expand and contract in order to generate the current of air. The generated air flow can be adapted to the shape of the evaporation surface. |
