Abstract
An electrical apparatus for killing insects has vertically disposed, concentrically arranged mesh electrodes interconnected by suitable switching means to a source of high voltage. The electrodes are supported at their lower ends by individual insulators establishing the lower ends of the electrodes both mutually spaced from each other as well as from the surrounding apparatus enclosure parts. These insulators are located entirely outwardly of the space between the mesh electrodes so that the region below the space between the electrodes is free of obstructions such that electrocuted insects will not be able to collect on the insulators and form an electrical short.
Claims3
In an electrical apparatus for killing insects having means for attracting the insects, first vertically extending mesh electrode means surrounding the atrracting means, second vertically extending mesh electrode means in spaced surrounding relationship to said first electrode means, a top and a bottom, the improvement comprising:
- a first pair of insulators affixed to the inwardly facing surface of the first electrode means edge margin and the bottom;
- and
- a second pair of insulators affixed to the outwardly facing surface of the second electrode means edge margin and the bottom;
- said first and second pairs of insulators being located outwardly of the space between the electrode means leaving said space therebetween free of all obstruction by said insulators.
