Abstract

An insect killing system optimized for mosquitoes uses multiple thermal gradients to simulate the breathing and body heat from animals, including human beings and fowl, to attract insects for subsequent electrocution. The system comprises an elongated, generally parallelepiped housing supported upon a lower base. A heating tower shrouded by the housing supports a spaced apart, generally pyramidal roof. Several slits penetrate the base to permit air entry. An internal fan draws air into the base where the air mixes with scent and pheromones. Mixed air is blown into and through the heating tower. An internal baffle divides the tower interior into separate, spaced apart compartments. A lower compartment houses a heater, and an adjacent upper compartment vents warmed air to atmosphere, creating numerous separate streams of warmed air that, to an insect, emulate human breathing. The baffle restricts air flow to create a pressure differential while ensuring adequate residence time to sufficiently warm the air. Heated air traversing the upper compartment is expelled through a plurality of discharge orifices. The resulting multitude of warm air currents creates an infrared signature emulating human breathing. Thermal and pressure differential gradients established by the baffle enhance the infrared illusion. Attracted mosquitoes are electrocuted by a high voltage grid. Several adjustable braces may be manually manipulated to clean the grid. A safety mesh extends between the base and the roof to prevent accidental shock.
