Patent ID: 7614180

Claim:
A flying insect trapping device having a fuel supply containing a combustible fuel, comprising: an insect trap chamber configured to receive flying insects through an insect inlet; a combustion chamber defined by at least one wall and including a heat zone having an interior space, combustion occurring in said heat zone to generate exhaust gas for attracting flying insects to said insect inlet; a heat exchanger element contained within said heat zone interior space of said combustion chamber to conduct heat generated by the combustion in said chamber away from said heat zone interior space and toward said combustion chamber wall, said heat exchanger element defining a plurality of channels that minimize disruption of exhaust gas flow through said chamber; a thermoelectric device having a first side in contact with said combustion chamber wall and a second side spaced from said combustion chamber wall, said thermoelectric device generating electric current from heat transferred from said combustion chamber wall, to said thermoelectric device first side and then to said thermoelectric device second side; and said electric current generated by said thermoelectric device being used to power a component of said device.
