  • Patent number: 6466739
    Abstract: An electric evaporator for insecticides or perfumes in liquid formulation, contained in a bottle which can be steadily inserted into a container, includes a wick, an element for housing and centering the wick and a respective electric heating device. The wick housing and centering element are joined to the walls of the container through elastic bridge-pieces which have the shape of a loop extending respectively in horizontal and vertical planes. A cam device, which is actuated manually outside of the container, allows displacement of the wick housing and centering element in a direction perpendicular to the axis of the wick, towards or away from the heating device.
