Portable electronic insect-killing device

A portable electronic insect-killing device comprising:

• a longitudinal handle having a power supply unit disposed therein;
• an insulating frame having a top frame portion, and a bottom frame portion longitudinally spaced apart from said top frame portion, said bottom frame portion being mounted on said handle;
• and
• a plurality of negative and positive bare wires which extend from said top frame portion to said bottom frame portion and are alternately arranged in parallel in a plane;
• said top frame portion having a front surface adjacent and parallel to the plane of said bare wires, and a plurality of spaced apart shallow recesses in said front surface to receive said negative and positive bare wires, said shallow recesses being spaced apart from each other by deep isolating valleys which are indented from said front surface to a depth greater than the depth of said shallow recesses, said shallow recesses and said deep isolating valleys having substantially the same length along said front surface along the direction of said negative and positive bare wires so that said front surface of said top frame portion is free of a part to bridge any two adjacent ones of said shallow recesses;
• and
• said bottom frame portion having a plurality of wire holes which are isolated from each other for passage of said negative and positive bare wires, respectively, a first power line to electrically connect with said negative bare wires, and a second power line to electrically connect with said positive bare wires, said first and second power lines being electrically connected to said power supply unit.
