PERMEABLE ELECTRICAL HEAT- RESISTANT FILM FOR VAPORISATION OF LIQUIDS FROM DISPOSABLE MOUTHPIECES COMPRISING VAPORISATION MEMBRANES

摘要

The device has a heating resistor (1) designed in the form of a metallic film or thin sheet e.g. double spiral (101) and/or wavy line with two ends. Intermediate spaces of the double spiral and/or wavy line are open and permeable to flowing fluids. Contact plates (13) are made from metallic film or thin sheet and connected with respective ends of the double spiral and/or wavy line. The contact plates are not directly connected with one another. The heating resistor is covered with an insulation layer that is made from polyimide, micanite or silicone. An independent claim is also included for an evaporation device.
