1. A device for dispensing volatile substances, the device comprising:
a container for receiving a substance to be dispensed;
at least one wick forming a capillary element in contact with the substance to be dispensed, said at least one wick being arranged at least partly in said container and said at least one wick having a substance dispensing region;
a heating element assigned to said wick;
a squeezing device assigned to said wick, said squeezing device having at least one squeezing element disposed to subject a squeezing region of said wick to a squeezing force for causing a defined substance quantity to be conveyed substantially in the direction of the substance dispensing region of said wick; and
said at least one squeezing element being arranged on said squeezing device so as to be displaceable between a home position and a squeezing position;
said squeezing device having an actuating device being coupled with said at least one squeezing element, and being configured to displace said at least one squeezing element in the direction of said squeezing region of said wick to said squeezing position;
said squeezing device having a restoring element configured to displace said at least one squeezing element from the squeezing position back into the home position; and
said restoring element being formed by an elastically resilient element which is compressible when said at least one squeezing element is transferred into the squeezing position and which, when there is a lack of force application by said squeezing device and/or said squeezing device is not actuated, said at least one squeezing element is configured to move automatically from the squeezing position back into the home position.
