摘要： An electrical heating device is disclosed that is suitable to vaporize air treatment chemicals from an impregnated substrate. The device is provided with a PCT heater held between electrical contacts and a spring that is compressed between the housing of the heating device and one of the electrical contacts to maintain pressure thereon in spite of thermal expansion of the housing, ensuring good electrical contact between the PCT heater and the electrical contacts.
