[0010] The present invention will be described below with reference to the drawings illustrating embodiments. FIG. 1 is a diagram showing an example of the appearance of an explosion-proof insect trap 100 according to this embodiment. As shown in FIG. 1, the explosion-proof insect trap 100 includes an irradiation unit 10 having an ultraviolet ray irradiation surface 11, a guard unit 20 arranged opposite the ultraviolet ray irradiation surface 11, and an insect trapping unit 30 attached to the guard unit 20. The explosion-proof insect trap 100 shown in FIG. 1 can be hung from a ceiling or the like, and is equipped with a power supply hanging bracket 81 and a hanging bracket 82. The ultraviolet ray irradiation surface 11 is rectangular. An LED substrate 12 is mounted on the ultraviolet ray irradiation surface 11. The irradiation unit 10 includes a power supply unit that supplies power to the LED substrate 12. The LEDs on the LED substrate 12 can irradiate ultraviolet rays having a peak wavelength within a desired range of 315 nm to 400 nm, for example. The LEDs on the LED substrate 12 can irradiate ultraviolet light in a direction intersecting the ultraviolet light irradiation surface 11, toward the guard part 20 and the insect trapping part 30. The irradiation part 10 is provided with a front glass (tempered glass) so as to cover the LED substrate 12.

[0011] The guard part 20 is rectangular in shape, with a length approximately equal to that of the ultraviolet irradiated surface 11 and a width greater than that of the ultraviolet irradiated surface 11. Insect trapping parts 30 are attached to both ends of the guard part 20 in the width direction. The insect trapping parts 30 have rectangular insect trapping paper 33. The insect trapping parts 30 are arranged in a second area 2 excluding the first area 1 corresponding to the ultraviolet irradiated surface 11 of the guard part 20. In the example of Figure 1, the insect trapping parts 30 have insect trapping paper 33 arranged in the second area 2 with the first area 1 in between.

[0012] Insects are attracted by the ultraviolet light emitted from the LEDs on the LED substrate 12, and insects flying toward the ultraviolet light irradiated surface 11 are captured by the insect paper 33 provided in the insect trapping section 30. According to this embodiment, no insect trapping space is required, and no suction section for sucking insects into the trapping space is required, so the explosion-proof insect trap 100 can be constructed with a simple structure and there is no risk of increased costs.

[0013] FIG. 2 is a diagram showing an example of the front of the explosion-proof insect trap 100 of this embodiment, and FIG. 3 is a diagram showing an example of the side as viewed from line AA in FIG. 2. The guard section 20 includes a rectangular frame member 22 and multiple rod-shaped members 23 and 24 fixed to the frame member 22. The rod-shaped members 23 and 24 are arranged in a lattice pattern with the frame member 22 as the outer periphery. The guard section 20 includes the lattice-shaped rod-shaped members 23 and 24, which provide gaps through which insects can pass. This allows insects attracted by ultraviolet light emitted from the LEDs on the LED substrate 12 to fly toward the insect paper 33, making it easy to capture the insects with the insect paper 33. Furthermore, the ultraviolet light emitted from the LEDs on the LED substrate 12 can be emitted without being blocked.

[0014] One end of the insect paper 33 has a holder part 31 that fits into a bracket 26 provided on the guard part 20, and the other end of the insect paper 33 has an attachment part 21 to which a spring 27 fixed to the guard part 20 with a screw 32 is attached. The insect paper 33 can be easily attached by fitting the holder part 31 on one end of the insect paper 33 into the bracket 26 and hooking the spring 27 onto the attachment part 21 on the other end of the insect paper 33. Furthermore, by utilizing the restoring force of the spring 27, the insect paper 33 can be attached while being tensioned.

[0015] The guard portion 20 is coated with nylon. The nylon coating is achieved by immersing the guard portion 20 in liquid resin. To immerse the guard portion 20 in liquid resin, suspension wires are welded to two locations on the guard portion 20 and the guard portion 20 is immersed while suspended by the suspension wires. After the nylon coating is applied, the suspension wires are cut. In FIG. 2 , the location indicated by the reference numeral 28 is the suspension wire mark left after the suspension wire is cut. In this embodiment, the suspension wire mark 28 restricts the movement of the spring 27. Specifically, by giving the suspension wire mark 28, which would normally remain, a rotation prevention function for other components, a unique function is given to what was originally a foreign object, reducing the sense of incongruity in the product. Furthermore, since there is no need for an additional rotation prevention mechanism, costs are reduced. Specifically, the spring 27 is restricted from rotating around the screw 32. This allows the spring 27 to be securely fixed.

[0016] As shown in FIG. 3, the explosion-proof insect trap 100 includes a guard mounting portion 50 extending from the irradiation portion 10 in a direction intersecting the ultraviolet irradiation surface 11. The guard mounting portion 50 can be composed of four rod-shaped members extending from four required locations on the irradiation portion 10. The guard portion 20 is detachably mounted to the guard mounting portion 50. Specifically, as shown in FIG. 2, the frame member 22 of the guard portion 20 is formed with a potbellied hole 25, which is a circular hole with a small groove. The guard portion 20 can be detached from the guard mounting portion 50 simply by slightly loosening the screws fastened to the guard mounting portion 50 and sliding the guard portion 20 up and down (or left and right). The insect trapping paper 33 can be replaced by replacing the guard portion 20.

[0017] As shown in FIG. 3, the explosion-proof insect trap 100 is provided with a tray 40 for receiving insects at one end of the guard section 20. The tray 40 is flat, and its length is approximately the same as that of the irradiation section 10, and its width can be approximately the distance between the guard section 20 and the irradiation section 10. The tray 40 may have a bent portion at the tip on the irradiation section 10 side. This allows it to catch insects that fly toward the ultraviolet irradiation surface 11 of the irradiation section 10 and hit the irradiation section 10, causing them to fall, or to catch dead insects that have detached from the insect paper 33.

[0018] 3, the irradiation unit 10 includes a housing 14 that houses the LED substrate 12. A front glass (tempered glass) 13 is provided on the irradiation surface side of the LED substrate 12. The housing 14 has a sealed structure.

[0019] Fig. 4 is a diagram showing an example of a side view seen from line BB in Fig. 2, and Fig. 5 is a diagram showing an example of a back view seen from line CC in Fig. 4. As shown in Fig. 4, the irradiation unit 10 has a rib structure (rib) 15 provided at a right angle to the surface of the housing 14. The provision of the rib structure 15 prevents the housing 14 from being deformed by an external force applied to the housing 14, and the strength of the housing 14 can be increased.

[0020] The distance between adjacent rib structures 15 can be, for example, 10 mm or more and 16 mm or less. If the distance is less than 10 mm, the number of rib structures 15 increases, increasing the weight of the explosion-proof insect trap 100. On the other hand, if the distance exceeds 16 mm, the strength of the housing 14 decreases.

[0021] 5, the orientation of rib structure 15 can be perpendicular to outer periphery 141 of housing 14. This allows rib structure 15 to be aligned with outer periphery 141 of housing 14 regardless of the shape of housing 14, thereby increasing the strength uniformly across the entire housing 14.

[0022] Figure 6 shows an example of the arrangement of insect paper 33. As mentioned above, Figure 6A shows the case where insect paper 33 is arranged in a second region with a first region corresponding to ultraviolet irradiated surface 11 in between. Insects flying towards ultraviolet irradiated surface 11 can be captured by insect paper 33 with the first region corresponding to ultraviolet irradiated surface 11 arranged in between.

[0023] FIG. 6B shows a case where the insect catching paper 33 is arranged in a second region around the first region corresponding to the ultraviolet ray irradiation surface 11. In the example of FIG. 6B, the insect catching paper 33 is arranged around the rectangular ultraviolet ray irradiation surface 11. The arrangement of the insect catching paper 33 can be changed as appropriate depending on the shape of the ultraviolet ray irradiation surface 11, etc. As shown in FIGS. 6A and 6B, in this embodiment, the insect catching paper 33 can be arranged in the second region excluding the first region corresponding to the ultraviolet ray irradiation surface 11 of the guard part 20. This makes it possible to capture insects with a simple structure.

[0024] 7 is a diagram showing an example of the mounting position of the power supply draw-out hanging metal fitting 81. Since the housing 14 of the explosion-proof insect trap 100 of this embodiment has a symmetrical shape, the mounting position of the power supply draw-out hanging metal fitting 81 can be easily changed by rotating the housing 180 degrees. In either case, the guard part 20 can be mounted so that the tray 40 is on the bottom side.

[0025] Figure 8 is a diagram showing another example of a mounting method for the explosion-proof insect trap 100. The example shown in Figure 8 shows a case where the explosion-proof insect trap 100 is mounted on a wall. A U-shaped mounting bracket (not shown) is attached to the wall, and the explosion-proof insect trap 100 can be fixed to the mounting bracket. The power outlet 83 can be attached to a required location on the wall.
