Sticking to the fan 35 is prevented.

  Next, the effect of the insect trap 10 having the above structure will be described.

  Although this insect trap 10 is installed in a factory, a warehouse, a store, etc., for example, the installation location will not be specifically limited if it is a place where the insect 1 needs to be captured. In the insect trap 10, the suction fan 35 is always operated and sucks the air in the decompression chamber 33 except when the capture filter 17 is replaced. The inside of the 1st ventilation path 51 and the 2nd ventilation path 52 is attracted | sucked via the exit 55, As a result, the suction | attraction force toward the 1st opening 31 and the 2nd opening 32 which comprise a suction port toward the ventilation path inside Is to be granted. Further, light L (laser) is projected from the light projecting unit 61 of the sensor 60 and is received by the light receiving unit 63.

  In the above state, as shown in FIG. 2, when the insect 1 attracted by the insect lamp 15 approaches the suction port including the first opening 31 or the second opening 32, suction is performed from the first opening 31 or the second opening 32. Then, the air is sucked into the first air passage 51 and the second air passage 52. Thereafter, the insect 1 is discharged from the discharge port 55 where the outlets of the air passages 51 and 52 are gathered, and is trapped in the capture filter 17 disposed in the decompression chamber 33 through the opening of the frame-shaped member 80. (See FIGS. 2 and 3).

  In the insect trap 10, as described above, the sensor 60 is disposed on the suction port side (the first opening 31 and the second opening 32 side) of the air passages 51 and 52. It is possible to reduce the possibility that the insect 1 that has passed through returns to the suction port side and is detected again. In addition, since the sensor 60 is disposed on the suction port side of each of the air passages 51 and 52, the insect 1 is less likely to accumulate near the sensor 60 than when the sensor 60 is disposed near the discharge port of the air passage. Therefore, it is possible to prevent the insect 1 from sticking to the sensor 60 and reducing the sensitivity of the sensor 60.

  In this embodiment, the sensor 60 is a portion adjacent to the suction ports (the first opening 31 and the second opening 32) of each of the air passages 51 and 52, and has a slit shape. It is comprised with the photoelectric sensor which consists of the light projection part 61 and the light-receiving part 63 which are arrange | positioned at 32 length direction both ends (refer FIG.2 and FIG.5). Therefore, the suction port can be arranged with a width as wide as possible near the insect light 15, and the insect 1 sucked from the suction port can be detected in the immediate vicinity of the suction port. The possibility that 1 will return to the suction port side again and be detected again can be further reduced.

  Further, in this embodiment, the suction port is constituted by the first opening 31 and the second opening 32, and the ventilation path communicates with the first opening 31 and is arranged on the back side of the inner wall 27. A passage 51 and a second air passage 52 that communicates with the second opening 32 and is formed below the shelf wall 28, and the outlets of the first air passage 51 and the second air passage 52 are gathered to form a discharge port. 55, and the sensor 60 has a structure provided at two locations, a portion near the first opening 31 of the first air passage 51 and a portion near the second opening 32 of the second air passage 52. (See FIGS. 2, 3 and 5), the following effects are brought about.

  In other words, the insect approaching the insect lamp 15 may continue to fly around the insect lamp 15 or may be stalled and dropped near the insect lamp 15. In this case, in the insect trap 10 of this embodiment, by adopting the above-described structure, the insect that continues to fly around the insect light 15 is the first provided on the inner wall 27 of the recess 26. As the insect 31 approaches the opening 31, it is sucked and captured, and the insect that stalls and falls near the insect lamp 15 is sucked and captured from the second opening 32 provided in the shelf wall 28 of the recess 26. The insects approaching the insect light 15 can be efficiently captured. Further, the first ventilation path 51 passes through the back side of the inner wall 27 and reaches the discharge port 55, and the second ventilation path 52 passes below the shelf wall 28 and reaches the discharge port 55. Thus, both the air passages 51 and 52 can be gathered at one discharge port 55 (see FIG. 3).

  Further, in this embodiment, as shown in FIGS. 7 and 8, a detachable frame member 80 is attached to the outlet side periphery of the discharge port 55, and the capture filter 17 is attached to the frame member 80. The opening edge portion of the can be detachably mounted. Therefore, when replacing the capture filter 17, the capture filter 17 is removed from the insect trap 10 together with the frame-shaped member 80, and the capture filter 17 is replaced with respect to the frame-shaped member 80. Since it can attach to the exit periphery of the discharge port 55, the replacement | exchange operation | work of the capture filter 17 can be performed in the place away from the insect trap 10, and workability | operativity becomes favorable.

  Further, in this embodiment, as shown in FIG. 8, the frame-shaped member 80 is provided with a support 85 for preventing the capture filter 17 from sticking to the suction fan 35. Therefore, even when the suction fan 35 is arranged close to the capture filter 17, it is possible to prevent the suction filter 17 from sticking to the suction fan 35 and reducing the suction force.
