A heat exchanger is in contact with a heater and is located at the point at which the substance is to be evaporated. The device has a wall power point connection (5) which has primary and secondary rotational couplings inside the housing (1a, 1b). Each rotational coupling has contacts which can be connected to corresp. contacts of the other coupling. The contacts are displaced through 90 degrees in the rotational coupling sections so that electrical connections can be made between the power point contacts (6) and the heater. |
