Benefits of technology
[0014]For example, varying heating capacities from different heating elements can be used to regulate the evaporation of the substances, usually aromatics or insecticides, to cause a rapid or slow evaporation. Because the evaporation capacity can be easily adapted to the substance being evaporated, a great variety of multi-functional applications is possible from a single evaporation device. A design of this type represents a simple and economic alternative to the evaporation devices currently known from the state of the art, where the degree of evaporation can be changed only in an expensive and complicated manner by mechanical means that adjusts the distance between the volatile substances and heating element. In addition, the risk that the threads which adjust the distance of the container to the heating element may become locked by components of the substances to be evaporated, is avoided.
[0027]Especially simple and rapid assembly of the heating device in the housing is possible if the housing is made from two parts, an upper shell and a lower shell. The upper shell and the lower shell can be connected with each other by locking and / or clip elements. The lower shell preferably contains connecting members to connect the container to the housing locking elements. At least one of the two shells is provided with aeration slit for the escape of the evaporated substance into the environment. The aeration slits are preferably made in the area above the wick end in the upper shell. The production of a housing of this type in two parts is especially simple and inexpensive.
Problems solved by technology
A disadvantage with prior evaporation devices is that it was not possible to adapt the degree of evaporation to the prevailing room conditions or to the different sensitivities of persons present in the room.
This has also not been possible with the prior evaporation devices.
This type of design, where the degree of evaporation is adjusted by changing the relative distance between the heating element and wick, is relatively expensive due to the number of complicated components required to effect the adjustments.
On the whole, this is a relatively expensive and complicated construction with a great number of additional components, making the evaporating device expensive to manufacture.
However, this method of adjusting the degree of evaporation is relatively complicated in construction and is also expensive to manufacture.
Moreover, it is a common feature among all these known evaporation devices that they are relatively large in size and therefore less attractive aesthetically.
The large size in design of the prior art is caused by the number of adjustment components needed to control the degree of evaporation.

Embodiment Construction
[0039]Referring now in more detail to the drawings, the invention will now be described in more detail.
[0040]FIGS. 1 and 2 show different schematic views of a heating device 1 with a heating block 2 as components of an evaporation device 3. Heating block 2 in the top plain view of FIG. 1 has an approximately rectangular form, with a wick opening 4 formed in an approximately central area of heating block 2. Wick opening 4 is approximately in the middle area between two heating elements in the form of electrical resistance heaters 5 and 6. As can best be seen in FIG. 2, heating elements 5 and 6 are located in openings 7 and 8 on heating block 2 and are encapsulated with highly heat-conductive material such as flame-resistant insulation is cement.
[0041]On the opposite opening walls, on either side of heating elements 5 and 6, slits 9-12 are made through which electrical lines 13-16 connect to heating elements 5 and 6 and are routed. FIG. 7 shows a schematic cross-section through heatin...

Abstract
An evaporation device is disclosed for evaporating volatile substances such as insecticides and aromatics of a type having a housing containing a heating block with a heating element, a container for a volatile substance to be evaporated, a wick having a wick end protruding out of the container into a wick opening in the heating block, a switching device for the activation and deactivation of the heating device, and an adjusting device for the adjustment of the degree of evaporation. Preferably, two heating elements with different heating capacity are carried by the heating block. The heating elements are operatively connected to the switching device to adjust the heat output of the heating device and the degree of evaporation of the volatile substance.
