Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in the conventional insect-catching device as described above, in order to make it easier for insects to enter the inside of the housing, it is better to have a wider opening. However, with a wide opening, an insect that has entered the inside of the housing may not contact the insect-catching adhesive sheet and may exit the housing through the opening, resulting in the escape of the insect.

[0006] Therefore, in view of such a situation, an object of the present invention is to provide an insect trap capable of improving insect-catching performance.

Means for Solving the Problems

[0007] The insect trap of the present invention includes a collection unit having a space for collecting insects to be captured inside. An attractant unit that emits an attractant medium for attracting the aforementioned insects into the collection unit, The collection unit includes a capture unit for capturing the insects, The collection unit has an entrance for allowing the insects to pass into the collection unit. The aforementioned entrance is An opening that communicates with the collection section, It has a closure portion that partially closes the opening and is configured to allow the attracting medium to pass from inside the collection portion to outside the collection portion.

[0008] In the insect trap with the above configuration, the blocking section that partially closes the opening that serves as the entry point for insects is also configured to allow the attractant medium to pass from the inside to the outside of the collection section. As a result, insects moving towards the outside of the collection section are blocked by the blocking section, while the attractant medium passes through the blocking section and exits from the inside to the outside of the collection section.

[0009] Therefore, the insect trap with the above configuration can more easily retain insects in the collection section without reducing the insect-attracting effect of the attractant medium, thereby improving insect-catching performance.

[0010] In the insect trap of the present invention, The attracting unit is configured to emit light as the attracting medium, The aforementioned occluded portion may be configured to be light-transmitting.

[0011] With this configuration, the occluded section can allow light generated by the attractant section as an attractant medium to pass through, thus improving insect trapping performance.

[0012] In the insect trap of the present invention, The closing portion may be configured to close off at least a part of the outer peripheral region of the opening, while leaving the central part of the opening open.

[0013] According to such a configuration, by closing the outer peripheral region of the opening, insects trying to go outside the collection part can be blocked, and by opening the central part of the opening, it is possible to make it easier for insects to enter the inside of the collection part through the opening.

[0014] In the insect trap of the present invention, The collection part may be configured to have a circulation route based on the entrance.

[0015] In this way, since it becomes easier for the insects in the collection part to continue flying in the circulation route, it is possible to easily keep the insects inside the collection part.

[0016] In the insect trap of the present invention, The collection part is cylindrical, The entrance may be formed on the cylindrical surface of the collection part.

[0017] In this way, by making the inner wall of the collection part round, it also becomes easier for the insects to continue flying.

[0018] In the insect trap of the present invention, The attracting part is arranged at the central part of the collection part, The circulation route may be constituted by the space around the attracting part among the internal spaces of the collection part.

[0019] In this way, since the insects are likely to keep flying around in the circulation route while being affected by the attracting medium, it becomes difficult for the insects to go outside the collection part.

[0020] In the insect trap of the present invention, The capturing part may be arranged at the lower part of the collection part.

[0021] In this way, the insects that have fallen due to fatigue from flying in the collection part can be dropped onto the insect-catching paper for capture.

[0022] The insect trap of the present invention, Inside the collection unit, a guide unit is provided which is arranged around the capture unit. The guide portion may have an inclined surface that slopes downward from above as it approaches the capture portion.

[0023] In this way, insects that fall around the capture unit can be gathered into the capture unit by the guide unit, thereby increasing the efficiency of insect capture by the capture unit. [Effects of the Invention]

[0024] As described above, the insect trap of the present invention can achieve the excellent effect of improving insect trapping performance. [Brief explanation of the drawing]

[Figure 6] Figure 6 is an explanatory diagram of the internal structure of the insect trap according to the same embodiment. [Figure 7] Figure 7 is an explanatory diagram showing the state of use of the insect trap according to the same embodiment. [Modes for carrying out the invention]

[0026] Hereinafter, an insect trap according to one embodiment of the present invention will be described with reference to the attached drawings. The insect trap according to this embodiment is for capturing flying insects.

[0027] As shown in Figures 1 to 3, the insect trap 1 comprises a collection unit 2 having a space inside for collecting insects to be captured, an attractant unit 3 that emits an attractant medium to lure insects into the collection unit 2, a capture unit 4 that captures insects inside the collection unit 2 as shown in Figure 4, a guide unit 5 that guides insects to the capture unit 4, and an imaging unit 6 for imaging insects captured by the capture unit 4.

[0028] The collection unit 2 is configured to have a housing 20 in which a space is formed inside and an opening 200 is formed that communicates with the inside and outside, and a closing part 21 that partially closes the opening 200 of the housing 20 (see Figures 1 to 3), and the opening 200 and the closing part 21 form an entrance for insects to pass into the housing 20.

[0029] The housing 20 includes a cylindrical body portion 201, a bottom portion 202 that closes one open end of the cylindrical body portion 201 in the axial direction, a top portion 203 that closes the other open end of the cylindrical body portion 201 in the axial direction, and a partition portion 204 that divides the internal space of the body portion 201 into a space on the bottom portion 202 side and a space on the top portion 203 side.

[0030] The opening 200 of the housing 20 is formed in the body portion 201. Furthermore, multiple openings 200 are formed in the body portion 201; in this embodiment, openings 200 are formed in three locations: the front, left side, and right side of the body portion 201. Thus, the openings 200 are formed in the cylindrical surface of the collection portion 2 (housing 20).

[0031] As shown in Figure 1, the closure portion 21 is formed to partially block the opening 200. In this embodiment, the closure portion 21 blocks the entire outer circumference of the opening 200. Therefore, the central part of the opening 200 remains open.

[0032] The attractant unit 3 in this embodiment is configured to emit light (attractant light) as an attractant medium.

[0033] More specifically, as shown in Figure 5, the attraction unit 3 includes a light source 30 that emits attraction light, and a base 31 provided inside the housing 20 to which the light source 30 is attached.

[0034] Furthermore, within the housing 20 of this embodiment, three attraction sections 3 are arranged to correspond to the number of openings 200. The three attraction sections 3 are positioned opposite the front opening 200, opposite the left side opening 200, and opposite the right side opening 200, respectively.

[0035] The light source 30 can be composed of, for example, a light-emitting diode or a fluorescent lamp.

[0036] Here, the blocking section 21 is configured to allow the attractant medium generated by the attractant section 3 to pass from the inside of the housing 20 to the outside of the housing 20. In this embodiment, the attractant section 3 is configured to emit attractant light as the attractant medium, so the blocking section 21 is made of mesh. As a result, the blocking section 21 is configured to block insects from trying to get out of the housing 20, while allowing the attractant medium to pass from the inside of the housing 20 to the outside.

[0037] The base 31 is configured to hang down from the partition 204 on the central side of the housing 20. The base 31 is positioned away from both the rear 201a and the front 201b of the body 201 (see Figure 6). As a result, a continuous space (circulation route) is formed between the three attraction parts 3 and the inner surface of the body 201 in the housing 20, with the three attraction parts 3 as the center.

[0038] The trapping unit 4 comprises an adhesive insect trapping paper 40 and a tray 41 for arranging the insect trapping paper 40, the tray 41 being positioned at the bottom 202 of the housing 20.

[0039] The tray 41 is configured to be able to move in and out of the housing 20, and in this embodiment, it is configured to be able to move in and out of the housing 20 through an insertion / removal opening 205 (see Figure 1) formed in the body portion 201.

[0040] The guide section 5 is arranged around the capture section 4. In this embodiment, the guide section 5 includes an end (referred to as the outer end) that is in contact with the inner surface of the body section 201 and an end (referred to as the inner end) that is positioned adjacent to the capture section 4 (tray 41).

[0041] Furthermore, as shown in Figure 4, the guide portion 5 includes an inclined surface 50 such that the inner end is positioned lower than the outer end.

[0042] This inclined surface 50 is formed such that its outer end is located outside and above the light source 30, its inner end is located inside and below the light source 30, and the central portion between the outer and inner ends passes below the light source 30.

[0043] In this embodiment, the guide section 5 has one inclined surface 50 formed on one side and one on the other side of the capture section 4 in the lateral direction.

[0044] The imaging unit 6 includes an imaging device 60 that images the insect trap paper 40 from above, and an illumination device 61 that irradiates the insect trap paper 40 with light.

[0045] The imaging device 60 is positioned in the center of the housing 20 (closer to the center of the housing 20 than the three bases 31) and is fixed to the partition 204 in a downward position (with the imaging direction facing the insect trapping paper).

[0046] The imaging unit 6 of this embodiment is configured to have a plurality (two) of illumination devices 61, and these two illumination devices 61 are arranged symmetrically with respect to the insect trap paper 40.

[0047] Each lighting device 61 is positioned above and outside the insect trap paper 40, with its optical axis facing the insect trap paper 40. As a result, the insect trap paper 40 is illuminated by light from both sides at an oblique angle from above by the lighting devices 61.

[0048] Furthermore, it is preferable that the length of the lighting device 61 be set to be the same as or greater than the length of the insect trap paper 40.

[0049] The configuration of the insect trap 1 according to this embodiment is as described above. Next, the usage state of the insect trap 1 will be explained.

[0050] The induced light generated by each light source 30 exits to the outside through the open area of ​​the opposing opening 200. The front opening 200 is completely closed off around its outer circumference by the closing section 21, but the closing section 21 allows the induced light to pass from the inside to the outside of the housing 20. Therefore, the induced light generated by the light source 30 exits from the inside to the outside of the housing 20 through the entire area of ​​the opening 200.

[0051] Insects attracted by the light from the light source 30 enter the interior of the housing 20 through the open area of ​​the opening 200.

[0052] Inside the housing 20, the blocking section 21 can block insects (I) flying outwards from the housing 20, making it easier to keep insects (I) inside the housing 20 (see Figure 7).

[0053] Furthermore, since the space inside the housing 20 forms a continuous circulating route around the entire circumference centered on the three attracting parts 3, insects inside the housing 20 continue to fly along the circulating route, and when they run out of energy, they fall onto the insect trapping paper 40 or the inclined surface 50 of the guide part 5.

[0054] Insects that fall directly onto the insect trap paper 40 are captured by the insect trap paper 40. In addition, insects that fall onto the inclined surface 50 of the guide section 5 slide along the inclined surface 50 and fall onto the insect trap paper 40. In this way, insects inside the housing 20 are captured by falling onto the insect trap paper 40.

[0055] Then, when imaging is performed by the imaging device 60, an image of the insect captured by the insect trap paper 40 is obtained.

[0056] In this embodiment, the insect trap paper 40 is illuminated from both the upper outer sides by two lighting devices 61 arranged symmetrically around the insect trap paper 40. As a result, the shadows of insects are less likely to fall on the insect trap paper 40, and thus, images of insects in good condition are clearly captured.

[0057] Thus, the insect trap 1 of this embodiment can improve the insect capture rate, and furthermore, it can obtain clear images of insects that have been captured in good condition.

[0058] As described above, in the insect trap 1 according to this embodiment, the blocking section 21 that partially closes the opening 200 which serves as an entrance for insects is also configured to allow attracting light, which serves as an attracting medium, to pass from the inside to the outside of the housing 20. Therefore, insects heading towards the outside of the housing 20 are blocked by the blocking section 21, while the attracting medium passes through the blocking section 21 and exits from the inside to the outside of the housing 20.

[0059] Therefore, the insect trap 1 can more easily retain insects inside the housing 20 without reducing the insect-attracting effect of the attractant medium, thereby achieving the excellent effect of improving insect-catching performance.

[0060] Furthermore, since the closing portion 21 is configured to close the outer periphery of the opening 200 while leaving the central part of the opening 200 open, it becomes easier for insects to enter the inside of the housing 20 through the opening 200 by leaving the central part of the opening 200 open, and it becomes easier to block insects from trying to get out of the housing 20 by closing the outer periphery of the opening 200.

[0061] Furthermore, in the insect trap 1 of this embodiment, since the insect trapping paper 40 of the capture unit 4 is located at the bottom of the housing 20, insects that fall due to fatigue from flying inside the housing 20 can be dropped onto the insect trapping paper and captured.

[0062] Furthermore, since the space within the housing 20 is formed as a circulating route that revolves around the opening 200, it is possible to keep insects flying around inside the housing 20.

[0063] Furthermore, by making the housing 20 cylindrical and giving the inner wall (the inner wall of the housing 20) a rounded shape, the number of inner corners formed inside the housing 20 is reduced, which reduces the number of places where insects tend to accumulate, making it easier for insects to continue flying.

[0064] Furthermore, since the circulation route within the housing 20 is a continuous space extending around the entire circumference centered on the attractant section 3, it becomes easier to keep insects flying while being attracted by the attractant section 3 within the housing 20.

[0065] Thus, the insect trap 1 of this embodiment makes it easier to keep insects inside the housing 20 by making it easier for them to continue flying, and it is also possible to efficiently tire out the insects inside the housing 20, thereby enabling efficient insect capture.

[0066] Furthermore, since the insect trapping paper 40 is surrounded by a guide section having an inclined surface 50 that slopes downward from above as one approaches the insect trapping paper 40, even if insects inside the housing 20 do not fall directly onto the insect trapping paper 40, the guide section can collect insects that fall around the capture section 4 into the capture section 4, thereby increasing the efficiency of insect capture by the capture section 4.

[0067] It should be noted that the insect trap according to the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0068] In the above embodiment, the insect trap 1 was configured to have an insect trapping function for capturing insects with the insect trapping paper 40, as well as an imaging function for capturing insects captured by the insect trapping paper 40. However, the configuration is not limited to this. For example, the insect trap 1 may be configured to have only the insect trapping function among the insect trapping function and the imaging function, or it may be configured to have an inspection function for inspecting the images of the captured insects in addition to the insect trapping function and the imaging function.

[0069] In this case, the insect trap 1 may, for example, be equipped with an inspection device that inspects the image captured by the imaging unit. The inspection device may be built into the insect trap 1, or it may be configured to communicate with the insect trap 1 via wired or wireless communication.

[0070] In the above embodiment, the collection unit 2 had three openings 200, but the configuration is not limited to this. For example, the collection unit 2 may have one or two openings 200, or it may have four or more openings 200.

[0071] Furthermore, in the above embodiment, a closing portion 21 was provided in one of the three openings 200, but for example, a closing portion 21 may be provided in all three openings 200, or a closing portion 21 may be provided in two of the three openings 200. In other words, if multiple openings 200 are formed in the collection unit 2, it is sufficient that a closing portion 21 is provided in at least one of the openings 200.

[0072] In the above embodiment, the closing portion 21 completely closed the outer periphery of the opening 200, but the configuration is not limited to this. For example, the closing portion 21 may be configured to partially close the outer periphery of the opening 200, or it may be configured to close the central part of the opening 200 and leave the outer periphery of the opening 200 open.

[0073] In the above embodiment, the attractant unit 3 was configured to generate light as an attractant medium, but the configuration is not limited to this. For example, the attractant unit 3 may be configured to generate odor or sound as an attractant medium.

[0074] Furthermore, although the occlusion portion 21 was configured to be light-transmitting by being made of mesh, for example, the occlusion portion 21 does not have to be made of mesh if it is transparent.

[0075] However, if the attractant medium generated by the attractant unit 3 is sound or odor, it is preferable that the occlusion unit 21 be made of mesh. [Explanation of Symbols]
