Device for the evaporation of volatile substances, in particular of aromatics and/or insecticides
First Claim
1. An evaporation device for evaporating volatile substances such as aromatics and/or insecticides comprising:
- a housing;
a receptacle arrangement carried by the housing having two receiving chambers for substances to be evaporated;
wicks inserted into the receiving chambers having wick ends protruding from the receiving chambers to provide wick end evaporation areas in which evaporated substance is present;
a heater arrangement carried in the housing for providing heat to the protruding wick ends adjacent said wick end evaporation areas for evaporation;
at least one blower for generating an air stream;
a tapered nozzle positioned generally transverse to said wick end evaporation areas for creating a targeted air stream directed across said evaporation areas to entrain and carry said evaporated substance out of said housing; and
a control unit for controlling the heater arrangement to evaporate the substances and for controlling the blower to be switched on at defined evaporation times.

Abstract
An evaporation device for evaporating volatile substances such as aromatics and/or insecticides comprising a housing; and a receptacle arrangement carried by the housing having two receiving chambers for substances to be evaporated. Wicks inserted into the receiving chambers include wick ends protruding from the receiving chambers. A heater arrangement is carried in the housing for providing heat to the protruding wick ends for producing an evaporated substance. At least one blower is provided for generating a targeted air stream to entrain the evaporated substance. A control unit is provided for controlling the heater arrangement to evaporate the substances and for controlling the blower to be switched on at defined evaporation times.

26. An evaporation device for evaporating volatile substances such as aromatics and/or insecticides comprising:
-
a housing; a receptacle arrangement carried by the housing having two receiving chambers for substances to be evaporated; wicks inserted into the receiving chambers having wick ends protruding from the receiving chambers; a heater arrangement carried in the housing for providing heat to the protruding wick ends; wick end evaporation areas adjacent wick ends in which an evaporated substance exists; at least one blower for generating an air stream; a control unit for controlling the heater arrangement to evaporate the substances and for controlling the blower to be switched on at defined evaporation times; and at least one tapered interior wall disposed between the blower and the protruding wick ends and forming a nozzle passage positioned generally transverse to said wick end evaporation areas for creating a targeted generally transverse air stream that impinges upon the wick end evaporation areas. - View Dependent Claims (27)

28. An evaporation device for evaporating volatile substances such as aromatics and/or insecticides comprising:
-
a housing; a receptacle arrangement carried by the housing having two receiving chambers for substances to be evaporated; wicks inserted into the receiving chambers having wick ends protruding from the receiving chambers to provide at least one wick end evaporation area in which an evaporated substance is present; a heater arrangement carried in the housing for providing heat to the protruding wick ends; at least one blower for generating an air stream; a control unit for controlling the heater arrangement to evaporate the substances and for controlling the blower to be switched on at defined evaporation times; at least one tapered interior wall disposed between the blower and the evaporation area forming a nozzle passage positioned generally transverse to said wick end evaporation area by which a targeted generally transverse air stream is directed toward and entrains said evaporated substance and at least one interior housing wall at least partially separating the targeted air stream and the heating arrangement to avoid cooling of the heating arrangement. - View Dependent Claims (29)
