Description

TECHNICAL FIELD The present invention relates to an insect trap, and more particularly to an insect trap for catching mosquitoes during the spawning season.

Conventionally, insect traps for catching pests such as mosquitoes and flies are known. For example, the insect trap described in Patent Document 1 includes an upper case, a lower case, a carbon dioxide gas generating source, and gas supply means. The upper case has a plurality of tapered through-holes in its upper part and an open lower part, and is engaged with the lower case. The lower case is open at the top and has a storage space in which the carbon dioxide gas generating source and the gas supply means are stored, and a support member that partitions the storage space from above. The carbon dioxide gas generating source and the gas supply means are arranged in the storage space. The support member is configured to allow the passage of carbon dioxide gas, and the carbon dioxide gas generated by the carbon dioxide generation means is diffused to the outside of the insect trap through the support member and the through hole of the upper case. Pests are lured by the carbon dioxide gas and invade the inside of the insect trap through the through holes. Since the through-holes are tapered, pests can easily enter the insect trap but have difficulty escaping from the insect trap. Thereby, this insect trap can trap pests inside the insect trap.

However, such an insect trap has a large number of components such as a carbon dioxide source and a carbon dioxide supply means, which increases manufacturing costs. Such traps also require a high cost of media for attracting pests.

By the way, among the pests described above, mosquitoes are particularly harmful because they serve as vectors for infectious diseases. Therefore, it is necessary to trap the mosquitoes and prevent the generation of the mosquitoes. During the spawning season, mosquitoes search for water with their sense of touch and lay their eggs in the water. Therefore, in order to prevent the occurrence of mosquitoes, it is effective not to create water pools for mosquitoes to lay their eggs. However, there are water places necessary for life, such as fire buckets and drainage basins. Therefore, as disclosed in Patent Document 2, there is known an insect trap that positively provides an egg-laying site to mosquitoes, causes them to lay eggs in the egg-laying site, and traps hatched mosquitoes.

However, this trap also has many components, which increases manufacturing costs. In addition, in this insect trap, eggs are hatched in the trap, so that the user is uncomfortable because he sees a large amount of dead mosquitoes every time he throws away the dead mosquitoes.

An insect trap according to an embodiment of the present invention will be described below with reference to the accompanying drawings. In the drawing, double-headed arrows X and Y indicate the horizontal direction, and double-headed arrow Z indicates the vertical direction.

FIG. 1 is a perspective view showing an insect trap 1 according to this embodiment. As shown in FIG. 1 , the insect trap 1 includes side walls 10 , a top plate 11 , a partition portion 13 and a support portion 14 . The top plate 11 corresponds to the "intrusion portion" of the present invention. The outer surface of the insect trap 1 is composed of a top plate 11 and side walls 10 extending downward from the top plate 11, and the bottom surface of the insect trap 1 is open. Partition part 13 and support part 14 are fixed to the inner surface of side wall 10 as will be described later.

As shown in FIGS. 2A and 2B, the insect trap 1 is placed over a container 3 that can store and has an open top. Although the container 3 is a fireproof bucket in this embodiment, it is merely an example, and the "container" in the present invention includes, for example, a drainage trough, a bucket for storing rainwater given to garden plants, and the like. I'm in. In the case of a fireproof bucket, the insect trap 1 is installed in the container 3 with the container 3 filled with water W.

Side wall 10 is formed in a tubular shape. Although the side wall 10 is formed cylindrical in this embodiment, it is merely an example, and may be formed, for example, in the shape of a square tube.

The upper surface of the top plate 11 is formed flat and has a plurality of entry holes 12 . Although the top plate 11 has 25 entry holes 12 in this embodiment, it may have only one entry hole 12, and the number of entry holes 12 is not particularly limited.

The side wall 10 and the top plate 11 are made of a material having light resistance and salt resistance, and may be made of stainless steel or aluminum, for example.

3 is a plan view of the insect trap 1, and FIG. 4A is a sectional view of the insect trap 1 shown in FIG. As shown in FIGS. 3 and 4, the entry hole 12 is tapered downward in a side view.

The inner diameter L1 of the inlet of the penetration hole 12 is configured to be approximately 10 mm. The body length of a typical mosquito M is about 4 mm to 6 mm, and the size of the hole through which the mosquito M can pass is 2 mm to 3 mm or more. can be done. The inner diameter L1 of the inlet of the penetration hole 12 in this embodiment is merely an example, and is not limited to this. For example, the inner diameter L1 of the inlet of the entry hole 12 may be configured to be 5 mm to 30 mm. In addition, by increasing the inner diameter L1 of the entry hole 12 of the insect trap 1, it is possible not only to facilitate the entry of mosquitoes M, but also to facilitate the accumulation of rainwater in the container 3 via the insect trap 1. .

The inner diameter L2 of the outlet of the entry hole 12 is 2 mm to 5 mm, preferably 3 mm to 4 mm. By narrowing the inner diameter L2 of the exit of the entry hole 12, the insect trap 1 prevents the mosquitoes M that have entered the trap 1 from the entry hole 12 from easily escaping from the inside of the insect trap 1 to the outside of the trap 1. do.

The partition part 13 extends horizontally and is fixed to the inner surface of the side wall 10 . The partition part 13 has a vent hole that allows the space above the partition part 13 and the space inside the container 3 to communicate with each other. As a result, the partition part 13 allows the mosquitoes M to detect the water W in the container 3 and allows the rainwater entering from the penetration hole 12 to pass into the container 3 . Moreover, the partition part 13 is configured so as not to retain enough water for the mosquitoes M to lay eggs. In this embodiment, the partition part 13 is made of a mesh material. The opening of the mesh material is 0.1 mm to 1 mm. Thereby, the partition part 13 prevents mosquitoes M from entering the container 3 from above the partition part 13 . The partition part 13 may be made of, for example, a porous material.

A distance L3 between the upper surface of the partition portion 13 and the lower end of the entry hole 12 is 2 mm to 4 mm, preferably 2 mm to 3 mm. As a result, the insect trap 1 can move the mosquitoes M from the exit of the entry hole 12 to the space S between the top plate 11 and the partition 13, and prevent the mosquitoes M from easily returning to the exit of the entry hole 12. can be prevented.

As shown in FIGS. 4 and 5 , the support portion 14 is formed in a donut shape in plan view, and is fixed to the inner surface of the side wall 10 below the partition portion 13 . A plurality of projections 14a projecting downward and extending in the radial direction are formed on the lower surface of the support portion 14 . In the present embodiment, four convex portions 14a are formed on the lower surface of the supporting portion 14 material on the front, rear, right, and left sides. When the insect trap 1 is installed in the container 3 , the lower surface of the convex portion 14 a is placed on the upper surface of the container 3 . Although the shape of the support portion 14 is donut-shaped in this embodiment, the support portion 14 is placed on the upper surface of the container 3 to support the side wall 10 and communicates the space inside the container 3 with the space below the partition portion 13 . is not particularly limited as long as it has For example, the support portion 14 is composed of a plurality of members fixed along the circumferential direction on the inner surface of the side wall 10 , and the members may be protrusions protruding in the radial direction of the side wall 10 or plates extending in the radial direction of the side wall 10 . may be formed into a shape.

The supporting portion 14 has a convex portion 14a, so that when the insect trap 1 is installed in the container 3, a gap is generated between the upper surface of the container 3 and the supporting portion 14. As shown in FIG. The height of the projection 14a is 0.5 mm to 1.5 mm, preferably 1 mm. Thereby, a gap of about 1 mm is formed between the lower surface of the support portion 14 and the upper surface of the container 3 . Thus, even when the container 3 is filled with rainwater and the water W in the container 3 overflows, the overflowing water is discharged out of the container 3 without entering the insect trap 1.例文帳に追加

The partition part 13 has a predetermined distance L4 between the upper surface of the partition part 13 and the upper surface of the container 3 when the insect trap 1 is installed in the container 3 so that the mosquitoes M that have reached the upper surface of the partition part 13 do not lay eggs. It is fixed to the side wall 10 at a position separated by more than a distance. Specifically, the partition portion 13 is fixed to the inner surface of the side wall 10 at a position where the distance L4 between the upper surface of the partition portion 13 and the lower surface of the support portion 14 is 5 mm to 100 mm, preferably 5 mm to 10 mm. Thereby, even when the container 3 is filled with rainwater, the distance between the upper surface of the partition part 13 and the water surface is maintained at 5 mm or more. Since the mosquito M has the property of laying eggs on the water surface, it cannot lay eggs if the distance from the water surface is greater than or equal to a certain value. Therefore, the insect trap 1 can prevent the mosquitoes M that have entered the insect trap 1 from laying eggs.

A length L5 below the support portion 14 of the side wall 10 is configured to be longer than a length L6 above the support portion 14 of the side wall 10 . Since the center of gravity of the insect trap 1 is located below the support portion 14, the insect trap 1 can be stabilized simply by being placed on the upper surface of the container 3. - 特許庁

Since the insect trap 1 has the above structure, it can be easily installed by simply placing it on the upper part of the container 3, and the water W in the container 3 attracts the mosquitoes M in the spawning season and catches the mosquitoes M in the space S. can be done. Moreover, the insect trap 1 prevents the trapped mosquitoes M from laying eggs by separating the partition part 13 from the water surface by a predetermined distance or more, thereby preventing the mosquitoes M from multiplying. In addition, the trap 1 keeps the mosquitoes M searching for a way to the water W below the eye by preventing them from laying eggs, thereby preventing the mosquitoes M from escaping from the trap 1.例文帳に追加

Furthermore, since the insect trap 1 prevents mosquitoes M from entering the container 3 and laying eggs, it is possible to prevent the water W in the container 3 from being contaminated. Since the insect trap 1 is simply placed on the upper part of the container 3, it can be removed from the container 3 without trouble when using the water W for fire prevention for extinguishing. In addition, the manufacturing cost of the insect trap 1 is kept low because of the small number of components, and the usage cost of the insect trap 1 does not occur because neither chemicals nor electric power are used.

Although the insect trap according to one embodiment of the present invention has been described above, the insect trap of the present invention is not limited to the above embodiment. For example, the insect trap 1 of the present invention may be implemented by the following modifications.

- As shown in FIG. 6, the lower surface of the support part 14 may have one or more recesses 14b instead of the protrusions 14a. In this case, the water overflowing from the container 3 is discharged to the outside through the gap formed by the concave portion 14b between the container 3 and the support portion 14. As shown in FIG.

- The insect trap 1 may have a roof on the top plate 11 . In this case, the insect trap 1 can prevent the entry hole 12 from being clogged with dust or the like by the roof. Moreover, the top plate 11 may not be flat, and may be configured in a hemispherical shape, for example. In this case, in order to keep the distance L3 between the lower end of the entry hole 12 and the partition portion 13 at 2 mm to 4 mm, the length of the entry hole 12 in the center of the top plate 11 is increased, or the shape of the partition portion 13 is changed to that of the top plate. 11, the distance L3 may be kept between 2 mm and 4 mm.

- The lower surface of the protrusion 14a may be made of a material with high frictional force or a material with flexibility. Thereby, the insect trap 1 can be prevented from sliding horizontally on the container 3 .

- The insect trap 1 may be made of a heat-resistant material in consideration of being used as an ashtray, for example. In this case, the heat-resistant material may be, for example, a heat-resistant plastic.
