ELECTRIC FUMIGATION DEVICE

摘要

An electrically activatable fumigating device (10), 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 (18) tha t 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 botto m of the cup. A eutectic thermal cut-off operates as a primary means of energy cut-off. The resistance heater (18) is also designed to fail after a specifi ed heating period as a redundant means of cut-off.
