By the abovementioned structural design, the bait is installed in the fixing element and an odor of the bait is used to attract files to approach the electrode net. Next, the flies are shocked electrically with a high voltage on the electrode net and finally, the dead or paralyzed flies are gathered in the collection barrel.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    (a) Field of the Invention 
         [0002]    The present invention relates to a technology of capturing flies, and more particularly to a flytrap which utilizes an odor to attract flies to approach and electroshocks the flies with an electrode grid discharging a low current and a high voltage, followed by gathering the dead or paralyzed flies in a collection barrel. 
         [0003]    (b) Description of the Prior Art 
         [0004]    In addition to easily becoming a medium for spreading diseases, Cyclorrhapha such as flies or fruit flies can be a major factor to affect hygiene of daily foods and fruits. 
         [0005]    There are generally several kinds of conventional ways to capture flies, as follows. The first one is to use a flyswatter to hit flies standing on a ground, a wall or a surface of other object. However, this swatting depends upon a person to hit the flies one by one, which not only extremely wastes time and labor, but distracts the person from working. Besides, the flies captured are limited. Therefore, this method indeed does not comply with demands. The second method uses a flypaper, wherein a layer of strong alluring adhesive is coated on a piece of paper to stick the flies standing on that paper. As the flypaper is adhered completely with the flies, it is not pleasant to see. Furthermore, the flypaper can be easily touched by children or pets that it is not hygienic. Hence, this method can cause a lot of troubles to a user. The third method is to spray a chemical insecticide into a herd of flies or the flies standing on a ground or a wall. As the effect of the insecticide is limited after diffusion, the insecticide can be easily inhaled by the user and the insecticide can be easily remained when the insecticide is sprayed on an object, a rather large risk to health of the user will be resulted, the side effect of the insecticide is too strong and the effect of capturing the flies is not significant. 
       SUMMARY OF THE INVENTION 
       [0006]    The object of the present invention is to provide a flytrap which utilizes primarily a bait to attract flies to approach and electroshocks the flies with an electrode grid discharging a low current and a low voltage, so as to effectively capture and gather the flies, thereby preventing from vector-borne infection.

         [0039]    In the flytrap of the present invention, the collection barrel  10  can be in all kinds of shapes, such as the round-cylinder-shaped collection barrel  10  in  FIG. 4  or the rectangular collection barrel  10   a  in  FIG. 6  and  FIG. 7 . Besides, the electrode net  24  and the safety net  25  are provide annularly and the through-holes  26  of the lower seat  22  are in a shape of fan. 
         [0040]    Furthermore, to prevent an odor of the bait from dissipating upward, when implementing, an upper side of the upper seat  21  can be provided with an upper cap  50  to extend a time of use of the bait, as shown in  FIGS. 1 to 5 . 
         [0041]    On the other hand, in the second preferred embodiment as shown in  FIG. 6  and  FIG. 7 , the collection barrel  10   a  is further provided with a support bracket  101  on which is provided with a stepped hole  102  to fix the lower seat  22  of the main unit  20 .

         [0042]    Accordingly, when the holding barrel  30   c , J-shaped hook  60   c  or V-shaped hooks  70   d  of the fixing element  30 ,  60 ,  70  is installed with the bait, the odor of bait can be utilized to attract the flies to enter into the electrode net  24  and then the flies will be shocked electrically with the high voltage by the electrode net  24  and drop into the collection barrel  10  from the through-holes  26  along the receiving chamber  23   a  of the guiding plate  23 . 
         [0043]    The flytrap of the present invention utilizes the bait to attract the flies to fly into the main unit  20  and then the flies will be shocked electrically by the electrode net  24 . Therefore, the flies can be rapidly and effectively captured and gathered to prevent from vector-borne infection, which is provided with an effect of improvement.
