  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
Embodiment 1 of the present invention will be described with reference to FIG. FIG. 1 is a schematic cross-sectional view of the insect trap 1. In the following description, the vertical and horizontal directions are defined in the direction shown in FIG. 1 unless otherwise specified.

  The insect trap 1 includes an insect attracting device 2 and an insect catching device 3, and is used by being suspended from a hook provided on a ceiling or a wall with the attracting device 2 facing upward.

  The insect attracting device 2 includes a substantially box-shaped insect attracting device main body 21 having an open bottom surface, a mounting substrate 22 housed in the insect attracting device main body 21, and a lower surface of the mounting substrate 22 facing the opening of the insect attracting device main body 21. A light-emitting diode (hereinafter abbreviated as LED) 23 as a light source for the insect attracting device and an insect attracting device body 21 are housed inside, and a driving power is supplied to the LED 23 using a battery (primary battery or secondary battery) as a power source. Power supply unit 24, reflecting plate 25 that reflects light emitted from LED 23 to the side, and a material that is transparent to light in the ultraviolet region, and closes the lower opening. And a cover 26 attached to the insect attracting apparatus main body 21. The power source 24 is not limited to a primary battery or a secondary battery, and a solar cell panel is attached to a portion other than the opening on the surface of the insect attracting device main body 21, and the electromotive force of the solar cell panel is used as a power source 24. May be operated.

  The LED 23 is attached to the mounting substrate 22 via soldering or a socket. In FIG. 1, only one LED 23 is mounted on the mounting board 22, but a plurality of LEDs 23 may be mounted.

  The wavelength of the irradiation light of the LED 23 is set to, for example, 300 nm or more and 400 nm or less, more preferably 350 nm or more and 370 nm or less. The wavelength of the irradiation light is determined based on the following reasons. That is, insects such as mosquitoes, moths, and moths have a particularly high running rate with respect to ultraviolet light having a wavelength of 330 nm or more and 420 nm or less, and the photocatalytic film 27 is irradiated with ultraviolet light having a wavelength of 400 nm or less. Since carbon can be generated, the wavelength of the irradiation light of the LED 23 is set to 300 nm or more and 400 nm or less in order to satisfy both conditions.

The ultraviolet light irradiated from the LED 23 is irradiated to the outside of the insect attracting device main body 21 through the cover 26, and a part of the cover 26 is made of, for example, TiO ₂ or Pt / TiO ₂ (titanium dioxide with platinum). A photocatalytic film 27 is formed. Thus, the photocatalyst film 27 is disposed within the illumination range of the LED 23, and a part of the ultraviolet light emitted from the LED 23 is irradiated to the photocatalyst film 27, and the photocatalyst film 27 generates active oxygen such as OH radicals. This active oxygen generates water and carbon dioxide by breaking down organic bonds.

  Moreover, since the insect attracting apparatus main body 21 has a lower opening closed by a cover 26 and the inside is sealed, waterproofness can be ensured and it can be used outdoors.

  On the other hand, the insect trapping device 3 has a flat box shape, and includes a insect trapping device body 31 provided with a through-hole 31a penetrating in the thickness direction at a portion facing the cover 26 of the insect attracting device 2, and the insect trapping device body 31. An adhesive part is formed on one side of the translucent belt-like release paper and the rollers 32 and 32 pivotally supported on both the left and right sides with the through hole 31a interposed therebetween. An insect trapping sheet 33 (capturing means) attached and wound around the roller 32 is provided.

  Elastic locking pieces 34 and 34 protrude from the left and right side surfaces of the insect catching device main body 31 toward the insect attracting device main body 21, and the locking claws 34 a at the tips of the elastic locking pieces 34 are connected to the side surfaces of the insect attracting device main body 21. The insect catching device main body 31 is attached to the insect attracting device main body 21 by being locked in the locking holes 21 a provided in the insect attracting device 21.

  On the other hand, when removing the insect catching device main body 31 from the insect attracting device main body 21, if each elastic locking piece 34 is bent in a direction away from the side surface of the insect attracting device main body 21, the engaging catch 34 a of the elastic locking piece 34 is engaged. Since the locked state with the stop hole 21 a is released, the insect attracting apparatus main body 21 can be easily detached from the insect capturing apparatus main body 31. Here, the elastic locking piece 34 of the insect catching device main body 31 and the locking hole 21a of the insect attracting device main body 21 constitute the mounting means. However, the mounting means is not intended to be limited to the above form, Conventionally known attachment means such as a hinge may be used.

  By the way, in the state where the insect capturing device main body 31 is attached to the insect attracting device main body 21, the light outlet of the insect attracting device main body 21 is arranged facing the through hole 31 a of the insect capturing device main body 31. Irradiation light passes through the through-hole 31a, passes through the insect catching sheet 33, and is irradiated to the outside. Further, the carbon dioxide generated by the photocatalytic film 27 is radiated to the outside from the lower opening of the through hole 31a through the gap between the inner wall of the insect capturing device main body 31 and the insect capturing sheet 33. Thus, the insects can be attracted by both the ultraviolet light from the LED 23 and the carbon dioxide generated by the photocatalytic film 27, and the insects gathered in the ultraviolet light and the carbon dioxide can be opened at the lower opening of the through hole 31a, Since it enters the inside of the insect trapping device main body 31 through an opening (not shown) provided on the side surface of the insect trapping device main body 31, the insect trapping sheet 33 arranged in the through hole 31a is used to capture the gathered insects. Can do. Note that a lattice-shaped or elongated hole-shaped net that does not allow an infant's finger to enter may be attached to the upper and lower openings of the through-hole 31a, thereby preventing the insect catching sheet 33 from being touched by mischief.

  Here, a handle (not shown) for winding operation is attached to at least one of the two rollers 32, and the roller 32 can be rotated by the handle operation. ing. The insect catching sheet 33 is wound around one roller 32 at the initial stage of use, but when many insects are caught in the part of the insect catching sheet 33 facing the through hole 31a, the handle 32 is operated by operating the handle. If 32 is rotated, the insect catching sheet 33 is unwound from one roller 32, and the insect catching sheet 33 is taken up by the other roller 32. A new insect can be captured in the space 31a. Here, a partition wall 35 for narrowing the entrance on the winding side of the insect catching sheet 33 protrudes in the vicinity of the roller 32 in the insect trapping device main body 31, and the roller 32 is narrowed by narrowing the entrance 35 a on the winding side. When the insect catching sheet 33 is wound up, the insects detached from the insect catching sheet 33 can be prevented from escaping to the outside. Note that a check valve (not shown) may be provided at the entrance 35a so that the insects do not escape to the outside, and the captured insects are more difficult to escape.

  When the insect catching sheet 33 is completely unwound from the one roller 32 and the insect catching sheet 33 is used up, the insect catching apparatus main body 31 that has been used is removed from the insect attracting apparatus main body 21, and the new insect capturing apparatus main body 31 is attached to the insect attracting apparatus main body 21. By attaching it, you can start capturing insects again. Thus, when replacing the insect trapping sheet 33, the entire insect trapping apparatus body 31 can be replaced without directly replacing the insect trapping sheet 33, so that the insect trapping sheet 33 can be easily replaced.

  As described above, the light in the ultraviolet region irradiated from the LED 23 is irradiated to the outside through the cover 26 and the insect capturing sheet 33 disposed in the through hole 31a of the insect capturing device main body 31, so It is possible to attract insects having phototaxis (for example, mosquitoes, moths, moths, etc.). Further, part of the ultraviolet light emitted from the LED 23 is irradiated onto the photocatalyst film 27 provided on the cover 26 to generate carbon dioxide, so that blood-sucking insects (for example, mosquitoes, gnats, etc.) that react with carbon dioxide are treated with ultraviolet light. It can be attracted by both light and carbon dioxide, which can enhance the insecticidal effect. Further, since carbon dioxide generated by the photocatalytic film 27 reaches a place where light does not reach, a blood-sucking insect in a place where light does not reach can be attracted by carbon dioxide, so that the attracting effect can be further enhanced.

  In addition, although the insect trap 1 of this embodiment is suspended and used, the installation method of the insect trap 1 is not limited to a hanging type, and it is downward from either the insect attracting device main body 21 or the insect capturing device main body 31. A leg portion (not shown) may be provided so as to project toward the side of the insect trapping apparatus and placed on the mounting surface in a state where a gap is provided between the insect trapping device main body 31 and the mounting surface.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic cross-sectional view of the insect trapping device. In the following description, the vertical and horizontal directions are defined in the direction shown in FIG. 2 unless otherwise specified.

  This insect trap 1 is composed of an insect attracting device 2 and an insect catching device 4, and is used in a state of being placed on a placing surface such as a floor with the attracting device 2 facing down. In addition, since the structure of the insect attracting apparatus 2 is substantially the same as Embodiment 1, the same code | symbol is attached | subjected to a common component and the description is abbreviate | omitted.

  The insect catching device 4 includes a cylindrical insect catching device main body 41 whose upper end is closed and whose lower end is opened. The side of the insect catching device main body 41 is opened downward. A notch 43 formed so as to narrow toward the upper side is provided. In addition, insect catching sheets 44 are attached to the left and right sides of the opening 42 at the bottom of the insect catching device main body 41 with the notch 43 interposed therebetween. The insect catching sheet 44 is translucent to ultraviolet light, and an adhesive portion is formed on one side or both sides.

  The insect attracting device main body 21 is placed with the opening facing upward, and a plurality of projecting pieces 28 (four when the insect attracting device main body 21 is square, three or more when circular) are directed upward. The insect catching device main body 41 is detachably attached to the insect attracting device main body 21 by fitting the projecting piece 28 into a locking recess (not shown) of the insect catching device main body 41. The Here, the attaching means is constituted by the projecting piece 28 of the insect attracting device main body 21 and the locking recess of the insect capturing device main body 41, but the attaching means is not intended to be limited to the above-mentioned form, but a conventional hinge or the like. Known attachment means may be used.

  In a state where the insect catching device main body 41 is attached to the insect attracting device main body 21, the insect catching sheet 44 faces the opening of the insect attracting device main body 21. Since the insect capturing device main body 41 is formed of a material having at least a side surface that is transparent to ultraviolet light, the ultraviolet light irradiated from the LED 23 of the insect attracting device 2 is transmitted through the insect capturing sheet 44 and the insect capturing device main body 41. To the outside. Further, when the photocatalyst film 27 receives the ultraviolet light from the LED 23 and generates carbon dioxide, the generated carbon dioxide is released to the outside through the notch 43 of the insect trap body 41. Thus, the ultraviolet light from the LED 23 and the carbon dioxide generated by the photocatalytic film 27 react with carbon dioxide and insects (eg, mosquitoes, moths, moths, etc.) that have a phototaxis with respect to light in the ultraviolet region. It can attract blood-sucking insects (for example, mosquitoes, gnats, etc.), and can enhance the insecticidal effect. Furthermore, since the carbon dioxide generated by the photocatalytic film 27 reaches a place where light does not reach, the insect attracting effect can be further enhanced. The width of the photocatalyst film 27 provided on the cover 26 is preferably substantially the same as the width of the notch 43 of the insect trapping apparatus main body 41, and carbon dioxide generated by the photocatalyst film 27 is efficiently external to the insect trapping apparatus main body 41. Can be released.

  The insects attracted by the ultraviolet light and carbon dioxide enter the inside through the notch 43 of the insect trapping device main body 41, so that the insects attracted by the trapping sheet 44 arranged in the insect trapping device main body 41 can be captured. it can. When various insects are captured on the insect catching sheet 44 and the catching effect of the insect catching sheet 44 is reduced, the insect catching device main body 41 is detached from the attracting device main body 21 and a new insect catching device main body 41 is attached to the insect attracting device main body 21. Then you can start capturing insects again. In this way, when the insect trapping sheet 44 is replaced, the entire insect trapping apparatus main body 41 can be replaced without directly replacing the insect trapping sheet 44, so that the insect trapping sheet 44 can be easily replaced.

  By the way, in this embodiment, the insect catching sheet 44 is used as the killing means. However, instead of the insect catching sheet 44, a container containing the insect catching liquid may be arranged inside the insect catching apparatus main body 41.

  Further, in each of the above-described embodiments, the insect trap 1 constituted by the insect attracting device 2 and the insect catching devices 3 and 4 has been described as an example. However, the insect attracting device 1 may be used only and the insect attracting effect is enhanced. The device 2 can be realized.

  It should be noted that a wide variety of different embodiments can be configured without departing from the spirit and scope of the present invention, and the present invention is not limited to a specific embodiment.
