Abstract
An electrically activatable fumigating device, methods of using it, and methods of constructing the device, are disclosed. The device is adapted to be plugged into a wall outlet. It is provided with a resistance heater that is housed in a lower recess of a heating cup by crimping edges of the recess around the heater. The cup focuses the heat of the heater adjacent the bottom of the cup. A eutectic thermal cut-off operates as a primary means of energy cut-off. The resistance heater is also designed to fail after a specified heating period as a redundant means of cut-off.
