A device for the release, in particular for evaporation, of volatile substances such as fragrances or active substances, has a container for a substance to be released. At least one wick as a capillary element is in contact with the substance to be released and at least partially in the receptacle and has a substance release region. The wick, preferably its substance release region, is assigned a heating element, preferably an electrical heating element. The wick is assigned a squeezing device with a squeezing element, by which a squeezing region of the wick can be subjected to a squeezing force and/or can be compressed, in particular for a defined short period of time and/or temporarily. A defined amount of substance, in particular at least the substance collected in the squeezing region, can be conveyed with a boost in the direction of the substance release region.
