Abstract
An insecticide dispenser capable of initiating the volatilization of a charge of insecticide to fumigate a room. The dispenser includes a container for the insecticide that is disposed upon a PTC heater. One side of the power supply necessary to initiate the chemical reaction passes directly through the cannister to the PTC heater. The other side of the power supply is connected through a support upon which the PTC heater rests. In the preferred embodiment, an electrical cut-off device is included in the circuit which will turn off the power when a predetermined temperature is attained which will be indicative of the initiation of the self-sustaining chemical reaction that causes the dispensing of the insecticide into the room.
Claims9
An insecticide dispenser including a housing, a PTC heater disposed therein, said PTC heater having an upper side and a lower side and an electrically conductive container for an insecticide disposed on the upper side of said PTC heater;
- and
- one side of a power supply means being connected to said conductive container and, in turn, to the upper side of said PTC heater;
- and
- an other side of the power supply being connected to the lower side of said PTC heater, whereby when said electrically conductive container is disposed on said PTC heater, a circuit will be formed on both sides of said PTC heater through said container, and further whereby heat is provided to initiate an exothermic self-sustaining chemical reaction in said container to volatilize insecticide therein.
