Abstract

The device comprises a handle 10 having a high voltage power supply unit disposed therein, a frame 20 mounted on the handle and two sets of bare output wires 30/40 arranged alternately in parallel within the frame. The top portion of the frame has a plurality of recesses 22 in its front face and an isolating valley 23 between each adjacent recess. The bottom portion of the frame has a plurality of cavities 25 in its front face staggered respectively with a plurality of flanges 24. An upper end of each of the bare output wires is secured in the recess, and a lower end of each of the wires extends through either a first set of holes 241 or a second set of holes 251 to connect with the power supply unit in the handle. The construction of the frame avoids loss of power due to shorting by moisture.

Description

IMPROVED PORTABLE ELECTRONIC INSECT-KILLING DEVICE The present invention relates to an insect-killing device, and more particularly to an improved portable electronic insect-killing device which isolates positive and negative bare output wires to avoid loss of power due to moisture causing a short circuit between the wires.

There are various kinds of conventional insect-killing devices, such as a flyswatter, a flyadhering paper, an electronic insect-killing light, and so on. Of the above mentioned insect-killing devices, a flyswatter is the least insect-killing effect since its operation depends on manpower. Yet the flyadhering paper and electronic insectkilling light are stationary, so that it is impossible for flying insects to be pursued and captured. To provide an insect-killing device with a much greater effect, the inventor proposed the US Patent No. 5533298 "A portable electronic insect-killing device". Said insect-killing device includes a handle and a frame. A top portion of the frame defines a plurality of recesses and a bottom portion of the frame defines a plurality of channels of distinct height corresponding to the recesses. Each channel defines a hole. A plurality of bare output wires A and a plurality of bare output wires B are alternately arranged in parallel within the frame. An upper end of each of the bare output wires A and the bare output wires B is alternately secured in the recess, and a lower end of each of the bare output wires A and the bare output wires B alternately extends through the respective hole of the channels to connect with a power supply unit in the handle. Also, an upper cover is combined with a lower cover to seal the lower ends of the wires A and B. Though this kind of insect-killing device is an improvement over conventional devices, it still has the disadvantage of a power loss occurring due to a short circuit caused by moisture, for example, when the device is used for pursuing and capturing a reptile on a wet surface.

The present invention provides an improved portable electronic insect-killing device to mitigate and/or obviate the aforementioned problems.

One object of the present invention is to provide an improved portable electronic insect-killing device which isolates positive and negative bare output wires effectively to avoid loss of power due to a short circuit caused by moisture.

In accordance with one aspect of the present invention, an improved portable electronic insect-killing device comprises a handle having a power supply unit disposed therein, a frame mounted on the handle and a plurality of bare output wires A and a plurality of bare output wires B alternately arranged in parallel within the frame. Wherein, a top portion of the frame defines a plurality of recesses in a front face thereof and an isolating valley between each adjacent recess. A bottom portion of the frame defines a plurality of cavities in a front face thereof respectively staggered with a plurality of flanges. The number of the cavities and flanges is equal to that of the recesses. Each section of the bottom portion of the frame defining a depth of each cavity and each of the flanges respectively define a first hole and a second hole. An upper end of each of the bare output wires A and the bare output wires B is secured in the recess, and a lower end of each of the bare output wires A and the bare output wires B respectively extends through the first hole and the second hole to connect with the power supply unit in the handle.

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

IN THE DARWINGS: FIG. 1 is a perspective view showing an improved portable electronic insect-killing device in accordance with the present invention; FIG. 2 is a partial schematic view showing a frame of the portable electronic insect-killing device of FIG. 1; FIG. 3 is a partial sectional side view of the portable electronic insect-killing device of FIG.1; and FIG. 4 is a partial sectional view of line 4-4 taken from the portable electronic insect-killing device of FIG.1.

Referring to FIG. 1, the improved portable electronic insect-killing device in accordance with the present invention comprises a handle 10 and a frame 20. The handle 10 is streamlined to have an elegant appearance and has a power supply unit (not shown) disposed therein. The handle 10 further has a switch 11 arranged thereon to control the power supply unit, a bedpiece 12 and a cover 13. The frame 20 is rectangularly shaped and has a central space 21 defined therein. A top portion of the frame 20 defines a plurality of recesses 22 in a front face thereof and an isolating valley 23 between respective adjacent recesses 22.

A bottom portion of the frame 20 defines a plurality of cavities 25 in a front face thereof respectively staggered with a plurality of flanges 24. The number of the cavities 25 and flanges 24 is equal to that of the recesses 22. Also, each section of bottom portion of the frame 20 defining a depth of the cavities 25 and each of the flanges 24 respectively define a first hole 251 and a second hole 241.

The bottom portion of the frame 20 further defines in a rear face thereof a first slot 26 for receiving a first power line 60, a second slot 27 for receiving a second power line 50, a first wire casing 28 and a second wire casing 29, as shown in FIG. 2.

Now referring to FIG. 2 and FIG. 3, a plurality of bare output wires A 30 and a plurality of bare output wires B 40 are alternately arranged in parallel within the frame 20. An upper end of each of the bare output wires A 30 and the bare output wires B 40 is secured in the recess 22, and a lower end of each of the bare output wires A 30 and the bare output wires B 40 respectively extends into the bedpiece 12 of the handle 10 through the first hole 251 and the second hole 241, as shown in FIG. 4. Thereafter, the lower ends of each of the bare output wires A 30 are connected to the first power line 50 and then to the power supply unit via the first wire casing 28, while the lower ends of each of the bare output wires B 40 are connected to the second power line 60 and then to the power supply unit via the second wire casing 29. Finally, the cover 13 is mounted to a front of the plurality of flanges and cavities 24 and 25 to seal the bare output wires 30, 40 and the bedpiece 12 is mounted to the wire casings 28, 29 and the slots 26 and 27.

With this arrangement, the bare output wires 30, 40 can be effectively isolated and therefore, a power loss of the wires resulting from a short circuit caused by moisture can be avoided.

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
