Description

飛翔害虫の誘引捕獲装置Attract capture device for flying insects
　本発明は、飛翔害虫の誘引捕獲装置に関する。 The present invention relates to a flying pest attracting and capturing device.
　従来、蚊やコバエ等の飛翔害虫を誘引捕獲するものとしていくつかの飛翔害虫の誘引捕獲装置が提案されている。
　例えば、特許文献１には、飛翔害虫を揮発性誘引剤（誘引源）により装置の内部に誘引し、殺虫剤の効果により誘引した飛翔害虫を駆除する装置が開示されている。このような誘引捕獲装置に用いられる殺虫剤の殺虫成分は人体に害を与えることはないが、ペット、乳幼児、高齢者、病弱者等のいる空間に対して使用するときには、少なからず心理的に抵抗を感じることがないとはいえない。
　そこで、特許文献２～４に示すように、二酸化炭素や餌（誘引剤）などの誘引源によりケース（筐体）近傍に誘引した飛翔害虫をケース内に配置された吸引ファン装置により吸気口から吸引し、収集することで、殺虫成分を用いない飛翔害虫の誘引捕獲装置が提案されている。 Conventionally, several flying insect attracting and capturing devices have been proposed as attracting and capturing flying insects such as mosquitoes and fly flies.
For example, Patent Literature 1 discloses a device that attracts flying pests to the inside of the device by a volatile attractant (attracting source) and controls the flying pests attracted by the effect of the insecticide. The insecticidal components of insecticides used in such attracting and capturing devices do not harm the human body, but when used in spaces with pets, infants, elderly people, sick people, etc. It cannot be said that there is no resistance.
Therefore, as shown in Patent Documents 2 to 4, flying insects attracted to the vicinity of the case (housing) by an attracting source such as carbon dioxide and bait (attractant) are sucked from the intake port by a suction fan device disposed in the case. An attracting and capturing apparatus for flying insects that does not use insecticidal components by sucking and collecting has been proposed.

　しかしながら、従来の吸引ファン装置を用いた誘引捕獲装置は、吸気口から吸引した外気を排気口から排気するため、誘引源の誘引成分が吸気口から吸引されて排気口から外気へ放出されてしまう。その結果、吸気口付近に誘引剤を留めることが難しく、ケース近傍に誘引した飛翔害虫を吸気口まで引き寄せることが困難であった。従って、従来の吸引ファン装置を用いた誘引捕獲装置は、捕獲効率を十分に高めることが困難であった。 However, since the attracting and capturing device using the conventional suction fan device exhausts the outside air sucked from the intake port from the exhaust port, the attracting component of the attracting source is sucked from the intake port and released from the exhaust port to the outside air. . As a result, it was difficult to keep the attractant in the vicinity of the intake port, and it was difficult to draw the flying pest attracted to the vicinity of the case to the intake port. Therefore, it is difficult for the attracting and capturing device using the conventional suction fan device to sufficiently increase the capturing efficiency.
　本発明は上記状況に鑑みてなされたもので、その目的は、飛翔害虫の捕獲効率を向上させることのできる飛翔害虫の誘引捕獲装置を提供することにある。 The present invention has been made in view of the above situation, and an object of the present invention is to provide a flying pest attracting and capturing device capable of improving the flying pest capturing efficiency.
　本発明に係る上記目的は、下記構成により達成される。
（１）　筐体と、前記筐体内に収容された誘引源と、前記筐体に形成され、前記誘引源に連通し、前記誘引源の誘引成分を前記筐体の外方に放出する第１開口部と、前記誘引源に連通し、前記第１開口部の近傍に形成された第２開口部と、前記第２開口部に隣接し、前記筐体内に収容された吸引ファン装置により外気を吸気するファン吸気部と、前記吸引ファン装置により吸引された外気を前記筐体外に排出する排気口を有する捕虫部と、を備えた飛翔害虫の誘引捕獲装置。 The above object of the present invention is achieved by the following configuration.

　上記（１）の構成の飛翔害虫の誘引捕獲装置によれば、ファン吸気部が第２開口部に隣接して形成されることで、ファン吸気部の吸引に伴って第２開口部から外気が流入する。第２開口部から流入した外気は、誘引源の周辺で滞留し、誘引源の誘引成分を第１開口部に押し出す。そこで、第１開口部から筐体の外方に放出された誘引成分は、第１開口部の近傍に滞留することができる。
　そして、第１開口部の近傍に滞留する誘引成分は、一部が近傍に位置するファン吸気部に吸引され、一部が第２開口部に流入する。外気と共に吸引された誘引成分の一部は、吸引ファン装置の排気流によって捕虫部の排気口から排出されて筐体の外方に拡散する。
　即ち、上記構成の飛翔害虫の誘引捕獲装置によれば、排気口から排出されて拡散した誘引成分によって、遠くにいる飛翔害虫が誘引捕獲装置に呼び寄せられる。そして、第１開口部の近傍に滞留させた高濃度の誘引成分によって、飛翔害虫はファン吸気部まで引き寄せられ、ファン吸気部に吸引される。そして、ファン吸気部に吸引された飛翔害虫は、捕虫部に捕獲される。従って、飛翔害虫を高効率で捕獲することができる。 According to the flying insect attracting and capturing device having the configuration (1), the fan intake portion is formed adjacent to the second opening portion, so that outside air is sucked from the second opening portion as the fan intake portion is sucked. Inflow. The outside air flowing in from the second opening stays around the attracting source and pushes the attracting component of the attracting source to the first opening. Therefore, the attracting component released from the first opening to the outside of the housing can stay in the vicinity of the first opening.
A part of the attracting component staying in the vicinity of the first opening is sucked into the fan intake part located in the vicinity, and a part thereof flows into the second opening. A part of the attracting component sucked together with the outside air is discharged from the exhaust port of the insect trapping part by the exhaust flow of the suction fan device and diffuses to the outside of the housing.
In other words, according to the flying insect attracting and capturing apparatus having the above-described configuration, the flying insect that is far away is attracted to the attracting and capturing apparatus by the attracting component that is discharged from the exhaust port and diffused. Then, the flying insect pest is attracted to the fan air intake section and sucked into the fan air intake section by the high concentration attracting component retained in the vicinity of the first opening. Then, the flying pest sucked into the fan intake section is captured by the insect capturing section. Therefore, flying pests can be captured with high efficiency.

By flowing into the second opening formed at the top, the air can stay well in the vicinity of the fan air intake.

Therefore, the fan intake portion 13 is formed by gaps between the plurality of louvers 11b.
　二酸化炭素発生装置５は、図３に示すように、紫外線を受光し、後述する有機ガス供給部としての誘引剤６から発生した有機ガスを分解して炭酸ガスを発生させる光触媒部である光触媒シート１８と、光触媒シート１８に紫外線を照射する紫外線照射部１５と、矩形状の光触媒シート１８の周縁部を挟持して該光触媒シート１８の上方に設置された紫外線照射部１５との間を所定間隔に保持する支持枠体１７，１９と、を備える。 As shown in FIG. 3, the carbon dioxide generator 5 is a photocatalyst sheet that is a photocatalyst unit that receives ultraviolet rays and decomposes an organic gas generated from an attractant 6 as an organic gas supply unit described later to generate carbon dioxide. 18, the ultraviolet irradiation unit 15 that irradiates the photocatalyst sheet 18 with ultraviolet rays, and the ultraviolet irradiation unit 15 that is disposed above the photocatalyst sheet 18 with the peripheral edge of the rectangular photocatalyst sheet 18 interposed therebetween at a predetermined interval. And support frame bodies 17 and 19 to be held on the surface.
　本実施形態の紫外線照射部１５は、基板上に所定間隔で配列された複数の紫外線ＬＥＤ１６を有する。紫外線照射部１５は、下方に配置された光触媒シート１８に紫外線ＬＥＤ１６が対向するようにして上部カバー１１の内面に固定される。
　紫外線ＬＥＤ１６は、例えば、アナターゼ型酸化チタンのバンドギャップ３．２ｅＶに相当する３８８ｎｍ以下の波長の紫外線を照射する。 The ultraviolet irradiation unit 15 of the present embodiment includes a plurality of ultraviolet LEDs 16 arranged on the substrate at predetermined intervals. The ultraviolet irradiation unit 15 is fixed to the inner surface of the upper cover 11 so that the ultraviolet LED 16 faces the photocatalyst sheet 18 disposed below.
The ultraviolet LED 16 irradiates, for example, ultraviolet rays having a wavelength of 388 nm or less corresponding to a band gap of 3.2 eV of anatase type titanium oxide.
　光触媒シート１８は、誘引剤６を収容した誘引剤カートリッジ６１と紫外線照射部１５の間に、上部カバー１１の内面に固定された支持枠体１７，１９に保持されて配設される。誘引剤６から揮発した有機ガスであるアルコールは、隔壁部材２０の中央開口部２１を介して光触媒シート１８に達する。
　光触媒シート１８は、例えば、アナターゼ型酸化チタン光触媒を担持するシートである。アナターゼ型酸化チタンは波長３８８ｎｍ以下の紫外線を受光すると、強い酸化力を持つヒドロキシルラジカル（ＯＨラジカル）を生成し易い正孔と強い還元力を持つスーパーオキサイドアニオンを生成し易い電子が発生する。ヒドロキシルラジカル、スーパーオキサイドアニオン、正孔、電子等の活性種は、誘引剤６から揮発したアルコールを炭酸ガスと水蒸気に分解する。アナターゼ型酸化チタンでは正孔及び電子が長寿命であるため、活性種を発生し続け、アルコールの分解を促進する。そして、アルコールから分解された炭酸ガス（二酸化炭素）は、誘引源として吸血意欲が高いメスの蚊を誘引することができる。 The photocatalyst sheet 18 is disposed between the attracting agent cartridge 61 containing the attracting agent 6 and the ultraviolet irradiation unit 15 while being held by the support frames 17 and 19 fixed to the inner surface of the upper cover 11. Alcohol, which is an organic gas volatilized from the attractant 6, reaches the photocatalytic sheet 18 through the central opening 21 of the partition member 20.
The photocatalyst sheet 18 is, for example, a sheet that supports an anatase-type titanium oxide photocatalyst. When anatase-type titanium oxide receives ultraviolet light having a wavelength of 388 nm or less, holes that easily generate hydroxyl radicals (OH radicals) having a strong oxidizing power and electrons that easily generate a superoxide anion having a strong reducing power are generated. Active species such as hydroxyl radicals, superoxide anions, holes, and electrons decompose alcohol volatilized from the attractant 6 into carbon dioxide and water vapor. In anatase-type titanium oxide, holes and electrons have a long life, so that active species continue to be generated and alcohol decomposition is promoted. Carbon dioxide (carbon dioxide) decomposed from alcohol can attract female mosquitoes with a high willingness to suck blood as an attraction source.

And an attractant cartridge 61 accommodated in the accommodation space 52.
　ボックス本体５３の前面には、上下方向に延びる把持部５８が突設されている。把持部５８の前面には、透明樹脂製の窓部５５が設けられており、誘引剤カートリッジ６１内に収容された誘引剤６の残量が外部から目視できるように構成されている。
　把持部５８の下部には、下面から突出させた係止突起（図示せず）を進退動させるロック装置５９が設けられている。ロック装置５９は、スイッチユニット３６の上面に形成された係止穴３７（図４参照）に係止突起が係止されることで、誘引剤ボックス５１の取出しを阻止している。 On the front surface of the box main body 53, a grip portion 58 extending in the vertical direction is projected.

［下部ユニット］
　下部ユニット７０は、図７に示すように、捕虫部である捕虫ボックス８１と、捕虫ボックス８１を収容する略直方体状のボックス収容空間７４が画成された基台７１と、を備える。 [Lower unit]
As shown in FIG. 7, the lower unit 70 includes an insect capturing box 81 that is an insect capturing unit, and a base 71 in which a substantially rectangular parallelepiped box accommodating space 74 that accommodates the insect capturing box 81 is defined.
　捕虫ボックス８１は、吸引ファン装置４０により吸引された飛翔害虫を収容する有底矩形筒状の容器である。捕虫ボックス８１の前面及び両側面は、通気ネット８３により構成されており、吸引ファン装置４０により吸引された外気を筐体外に排出する排気口とされている。即ち、排気口としての通気ネット８３は、飛翔害虫を通さず、気流のみを排出する微細な開口を有するものであり、金属メッシュやプラスチックメッシュ、或いは不織布などで形成される。 The insect trapping box 81 is a bottomed rectangular tube-shaped container that accommodates flying insects sucked by the suction fan device 40. The front surface and both side surfaces of the insect trapping box 81 are constituted by a ventilation net 83 and serve as an exhaust port for discharging outside air sucked by the suction fan device 40 to the outside of the housing. That is, the ventilation net 83 as an exhaust port has a fine opening that does not pass flying insects and discharges only the air current, and is formed of a metal mesh, a plastic mesh, or a nonwoven fabric.
　なお、通気ネット８３は、開口が小さすぎると、気流に対する抵抗が大きくなると共に捕獲された飛翔害虫や埃などが容易に閉塞し、吸引ファン装置の吸引力が低下する。また、通気ネット８３の開口が大きすぎると、蚊などの飛翔害虫に容易に逃げられてしまう。従って、通気ネット８３の開口は、捕獲対象となる飛翔害虫の大きさなどに応じて、適宜設定される。 Note that if the opening of the ventilation net 83 is too small, resistance to the air current increases and trapped flying insects and dust are easily blocked, and the suction force of the suction fan device is reduced. Further, if the opening of the ventilation net 83 is too large, it can be easily escaped by flying insects such as mosquitoes. Therefore, the opening of the ventilation net 83 is appropriately set according to the size of the flying pests to be captured.
　捕虫ボックス８１の前面には、上下方向に延びる把持部８２が突設されている。把持部８２の上部には、上面から突出させた係止突起８７を進退動させるロック装置８８が設けられている。ロック装置８８は、基台７１の天板に形成された係止穴７９に係止突起８７が係止されることで、捕虫ボックス８１の取出しを阻止している。 On the front surface of the insect trapping box 81, a gripping portion 82 extending in the vertical direction is projected. On the upper part of the gripping part 82, a locking device 88 is provided for advancing and retracting a locking projection 87 protruding from the upper surface. The locking device 88 prevents the insect capturing box 81 from being taken out by the locking projection 87 being locked in a locking hole 79 formed in the top plate of the base 71.
　そして、ロック装置８８の係止突起８７は、一対の押しボタン８５が押圧操作されることで、下方に移動して係止穴７９との係止が解除される。そこで、一対の押しボタン８５を押圧操作しながら把持部８２を持って捕虫ボックス８１を手前に引き出すことで、捕虫ボックス８１を基台７１のボックス収容空間７４から取り出すことができる。即ち、このようなロック装置８８が設けられることで、子供のいたずらなどにより捕虫ボックス８１が誘引捕獲装置１から不用意に取り出されるのを防止することができる。 Then, when the pair of push buttons 85 are pressed, the locking protrusions 87 of the locking device 88 move downward and the locking with the locking holes 79 is released. Therefore, the insect trapping box 81 can be taken out from the box accommodating space 74 of the base 71 by holding the gripping portion 82 and pulling out the insect trapping box 81 while pressing the pair of push buttons 85. That is, by providing such a locking device 88, it is possible to prevent the insect trapping box 81 from being inadvertently taken out of the attracting and capturing device 1 due to a child's mischief or the like.
　ところで、本実施形態の誘引捕獲装置１では、捕虫ボックス８１を取り出さない限り、飛翔害虫は外に出られず、吸引ファン装置４０の風に当たり続けるので、乾燥によって殆ど死んでしまう。しかしながら、まれに捕獲した飛翔害虫が捕虫ボックス８１内で死なず、捕虫ボックス８１を取り出した際に逃げ出すことがある。そこで、図７に示したように、捕虫ボックス８１内の底面には、粘着シート９０を敷設してもよい。粘着シート９０は、捕虫ボックス８１内に捕獲した飛翔害虫を粘着シート９０に粘着することができる。即ち、捕獲した飛翔害虫が粘着シート９０に粘着されることで、捕獲された飛翔害虫が捕虫ボックス８１の開閉時に逃げ出すことを防ぐことができ、誘引捕獲装置１の捕獲力を高めることができる。 By the way, in the attracting and capturing apparatus 1 of this embodiment, unless the insect capturing box 81 is taken out, the flying pests do not go outside and continue to hit the wind of the suction fan device 40, and thus almost die by drying. However, rarely captured flying pests do not die in the trapping box 81 and may escape when the trapping box 81 is removed. Therefore, as shown in FIG. 7, an adhesive sheet 90 may be laid on the bottom surface in the insect capturing box 81. The adhesive sheet 90 can adhere the flying pests captured in the insect capturing box 81 to the adhesive sheet 90. That is, the captured flying pest is adhered to the adhesive sheet 90, so that the captured flying pest can be prevented from escaping when the insect capturing box 81 is opened and closed, and the capturing power of the attracting and capturing device 1 can be increased.
　基台７１は、底部に電源ユニット７５が設けられ、前面及び両側面には捕虫ボックス８１の通気ネット８３が露呈する窓開口７３が形成されている。電源ユニット７５は、紫外線照射部１５の紫外線ＬＥＤ１６や吸引ファン装置４０に電力を供給し、これらを駆動する。電源ユニット７５から引き出された電源コード７７は、居室内のコンセントに接続される。
　基台７１の天板には、一体成形された格子の格子間の開口により通気口７２が形成されている。通気口７２は、基台７１の上方に配置される吸引ファン装置４０の排出側に連通する。 The base 71 is provided with a power supply unit 75 at the bottom, and a window opening 73 through which the ventilation net 83 of the insect trapping box 81 is exposed is formed on the front surface and both side surfaces. The power supply unit 75 supplies power to the ultraviolet LED 16 and the suction fan device 40 of the ultraviolet irradiation unit 15 and drives them. The power cord 77 drawn out from the power supply unit 75 is connected to an outlet in the living room.
A ventilation hole 72 is formed in the top plate of the base 71 by openings between lattices formed integrally. The vent 72 communicates with the discharge side of the suction fan device 40 disposed above the base 71.
　次に、上記した本実施形態に係る誘引捕獲装置１の構成の作用を説明する。
　本実施形態に係る誘引捕獲装置１を作動させると、中間部ユニット３０内の吸引ファン装置４０のプロペラ４４が回転すると共に、紫外線照射部１５の紫外線ＬＥＤ１６が点灯する。
　プロペラ４４が回転すると、図８の矢印（Ｘ１）によって示されるように、上部ユニット１０のファン吸気部１３から連通路２４を介して、外気が吸引ダクト４１の吸引路４３に吸引される。吸引ファン装置４０により吸引された外気は、捕虫ボックス８１の通気ネット８３から下部ユニット７０外へ排出される。 Next, the effect | action of the structure of the attraction capture apparatus 1 which concerns on this embodiment mentioned above is demonstrated.
When the attracting and capturing device 1 according to the present embodiment is operated, the propeller 44 of the suction fan device 40 in the intermediate unit 30 rotates and the ultraviolet LED 16 of the ultraviolet irradiation unit 15 is turned on.
When the propeller 44 rotates, outside air is sucked into the suction path 43 of the suction duct 41 from the fan intake section 13 of the upper unit 10 through the communication path 24 as indicated by an arrow (X1) in FIG. The outside air sucked by the suction fan device 40 is discharged out of the lower unit 70 from the ventilation net 83 of the insect trapping box 81.
　誘引剤カートリッジ６１内に収容された誘引剤６から揮発した有機ガスであるアルコールや誘引成分は、図８の矢印（Ｙ１）によって示されるように、蓋体６３の貫通穴６４から上方の上部ユニット１０における隔壁部材２０の中央開口部２１に向けて予め拡散する。そこで、誘引源である誘引剤６の誘引成分は、収容空間７における誘引剤カートリッジ６１の上方部（Ｓ）に滞留する。 The alcohol or the attracting component, which is an organic gas volatilized from the attracting agent 6 accommodated in the attracting agent cartridge 61, as shown by the arrow (Y 1) in FIG. 10 is diffused in advance toward the central opening 21 of the partition wall member 20. Therefore, the attracting component of the attracting agent 6 as the attracting source stays in the upper part (S) of the attracting agent cartridge 61 in the accommodation space 7.
　紫外線ＬＥＤ１６が点灯した二酸化炭素発生装置５は、誘引剤６から揮発したアルコールを分解して炭酸ガスを発生させる。従って、誘引源である二酸化炭素発生装置５が発生した炭酸ガスも、収容空間７における誘引剤カートリッジ６１の上方部（Ｓ）に滞留する。 The carbon dioxide generator 5 in which the ultraviolet LED 16 is turned on decomposes the alcohol volatilized from the attractant 6 and generates carbon dioxide. Therefore, the carbon dioxide gas generated by the carbon dioxide generator 5 as an attracting source also stays in the upper part (S) of the attracting agent cartridge 61 in the accommodation space 7.
　図１～図３に示したように、外気を吸引する一対のファン吸気部１３は、連通路２３を介して収容空間７に連通する第２開口部１４の両側に隣接して形成されている。そこで、ファン吸気部１３の吸引に伴って第２開口部１４の近傍に生じる気流によって、図９の矢印（Ｘ２）によって示されるように、上部ユニット１０の第２開口部１４から連通路２３を介して、外気が収容空間７に流入する。 As shown in FIGS. 1 to 3, the pair of fan intake portions 13 that sucks outside air are formed adjacent to both sides of the second opening portion 14 that communicates with the accommodation space 7 via the communication passage 23. . Therefore, as indicated by the arrow (X2) in FIG. 9, the communication path 23 passes through the communication path 23 from the second opening 14 of the upper unit 10 by the air flow generated in the vicinity of the second opening 14 due to the suction of the fan intake portion 13. Accordingly, outside air flows into the accommodation space 7.
　第２開口部１４から連通路２３を介して収容空間７に流入した外気は、誘引剤カートリッジ６１の上方部（Ｓ）周辺で滞留し、図８の矢印（Ｚ１）によって示されるように、炭酸ガス及び誘引剤６の誘引成分が放出路２２を介して第１開口部１２に押し出される。そこで、第１開口部１２から筐体３の外方に放出された炭酸ガス及び誘引剤６の誘引成分は、第１開口部１２の近傍における近傍部（Ｔ）に滞留することができる。 The outside air that has flowed into the accommodation space 7 from the second opening 14 via the communication passage 23 stays around the upper portion (S) of the attractant cartridge 61, and as shown by the arrow (Z1) in FIG. The gas and the attracting component of the attracting agent 6 are pushed out to the first opening 12 through the discharge path 22. Therefore, the carbon dioxide gas released from the first opening 12 to the outside of the housing 3 and the attracting component of the attracting agent 6 can stay in the vicinity (T) in the vicinity of the first opening 12.
　そして、第１開口部１２の近傍における近傍部分（Ｔ）に滞留する炭酸ガス及び誘引剤６の誘引成分は、図９の矢印（Ｘ３）によって示されるように、一部が近傍に位置するファン吸気部１３に吸引され、一部が第２開口部１４に流入する。外気と共に吸引された誘引成分の一部は、吸引ファン装置４０の排気流によって捕虫ボックス８１の通気ネット８３から排出されて筐体３の外方に拡散する。 The carbon dioxide and the attracting component of the attracting agent 6 that are retained in the vicinity (T) in the vicinity of the first opening 12 are partly located in the fan as indicated by the arrow (X3) in FIG. A part of the air is sucked into the air intake 13 and flows into the second opening 14. Part of the attracting component sucked together with the outside air is discharged from the ventilation net 83 of the insect trapping box 81 by the exhaust flow of the suction fan device 40 and diffuses outside the housing 3.
　即ち、本実施形態に係る飛翔害虫の誘引捕獲装置１によれば、捕虫ボックス８１の通気ネット８３から排出されて拡散した炭酸ガス及び誘引剤６の誘引成分によって、遠くにいる蚊などの飛翔害虫が誘引捕獲装置１に呼び寄せられる。
　そして、第１開口部１２の近傍における近傍部（Ｔ）に滞留させた高濃度の誘引成分によって、飛翔害虫はファン吸気部１３まで引き寄せられ、ファン吸気部１３に吸引される。ファン吸気部１３に吸引された飛翔害虫は、捕虫ボックス８１に捕獲される。従って、飛翔害虫を高効率で捕獲することができる。 That is, according to the flying insect attracting and capturing apparatus 1 according to the present embodiment, flying insects such as mosquitoes in the distance by the attracting component of the carbon dioxide gas and the attracting agent 6 discharged and diffused from the ventilation net 83 of the insect capturing box 81. Is attracted to the attracting and capturing device 1.
Then, the flying pest is attracted to the fan air intake portion 13 and sucked into the fan air intake portion 13 by the high concentration attracting component retained in the vicinity (T) in the vicinity of the first opening portion 12. The flying pest sucked by the fan intake unit 13 is captured by the insect capturing box 81. Therefore, flying pests can be captured with high efficiency.
　また、本実施形態に係る飛翔害虫の誘引捕獲装置１では、第１開口部１２が、筐体３における上部カバー１１の上面部１１ａに形成され、第２開口部１４及びファン吸気部１３が、筐体３の側面部である上部ユニット１０の長手方向両端に形成されている。
　そこで、上部カバー１１の上面部１１ａに形成された第１開口部１２から放出された炭酸ガス及び誘引剤６の誘引成分は、上部カバー１１の上面部１１ａに沿って流れて側面部に形成された第２開口部１４に流入することで、ファン吸気部１３付近に良好に滞留することができる。 Further, in the flying insect attracting and capturing apparatus 1 according to the present embodiment, the first opening 12 is formed in the upper surface portion 11a of the upper cover 11 in the housing 3, and the second opening 14 and the fan intake portion 13 are It is formed at both ends in the longitudinal direction of the upper unit 10 which is a side surface portion of the housing 3.
Therefore, the carbon dioxide gas released from the first opening 12 formed in the upper surface portion 11 a of the upper cover 11 and the attracting component of the attractant 6 flow along the upper surface portion 11 a of the upper cover 11 and are formed on the side surface portion. By flowing into the second opening 14, the air can stay well in the vicinity of the fan intake portion 13.
　また、本実施形態に係る飛翔害虫の誘引捕獲装置１では、飛翔害虫を誘引する誘引源が、誘引剤６及び二酸化炭素発生装置５を有している。
　そこで、例えば、誘引剤６の糖分を含む誘引成分によって食欲を有するオスの蚊や吸血意欲が低いメスの蚊を誘引し、二酸化炭素発生装置５が発生する二酸化炭素によって吸血意欲が高いメスの蚊を誘引することで、より多くの蚊を確実に誘引することができる。なお、本発明の誘引捕獲装置１は、必ずしも複数の誘引源を必要とするものではなく、誘引剤６又は二酸化炭素発生装置５の少なくとも一方の誘引源を有するものでもよい。 Further, in the flying pest attracting and capturing apparatus 1 according to the present embodiment, the attracting source for attracting the flying pest includes the attracting agent 6 and the carbon dioxide generating device 5.
Therefore, for example, a female mosquito who attracts male mosquitoes with appetite and female mosquitoes with low blood intake will be attracted by the attracting component containing the sugar of the attractant 6, and females with high willingness to absorb blood will be generated by the carbon dioxide generator 5. By attracting, more mosquitoes can be surely attracted. The attracting and capturing device 1 of the present invention does not necessarily require a plurality of attracting sources, and may have at least one attracting source of the attracting agent 6 or the carbon dioxide generating device 5.
　また、本実施形態に係る飛翔害虫の誘引捕獲装置１では、二酸化炭素発生装置５が、有機ガスを発生する誘引剤６と、紫外線を照射する紫外線照射部１５と、紫外線を受光し、有機ガスを分解して炭酸ガスを発生させる光触媒部である光触媒シート１８と、を有する。
　そこで、例えば、有機ガスを分解して炭酸ガスを発生させる効率が非常に高いアナターゼ型酸化チタン光触媒を使用することで、炭酸ガスを高効率で発生させることができ、蚊の捕集効率が高い誘引捕獲装置１を提供できる。勿論、本発明の二酸化炭素発生装置は、本実施形態の二酸化炭素発生装置５に限らず、公知の種々の二酸化炭素発生装置を用いることができる。 Further, in the flying insect attracting and capturing apparatus 1 according to the present embodiment, the carbon dioxide generating device 5 receives the attracting agent 6 that generates organic gas, the ultraviolet irradiation unit 15 that irradiates ultraviolet light, the ultraviolet light, and the organic gas. And a photocatalyst sheet 18 that is a photocatalyst portion that generates carbon dioxide gas by decomposing the slag.
Therefore, for example, by using anatase-type titanium oxide photocatalyst that is very efficient in decomposing organic gas and generating carbon dioxide, carbon dioxide can be generated with high efficiency, and mosquito collection efficiency is high. The attraction capture device 1 can be provided. Of course, the carbon dioxide generator of the present invention is not limited to the carbon dioxide generator 5 of the present embodiment, and various known carbon dioxide generators can be used.
　また、本実施形態に係る飛翔害虫の誘引捕獲装置１では、捕虫ボックス８１が、吸引ファン装置４０により吸引された飛翔害虫を粘着する粘着シート９０を有してもよい。
　そこで、捕虫ボックス８１に捕獲した飛翔害虫を粘着シート９０に粘着することで、飛翔害虫を効率的に確実に駆除することができる。 Further, in the flying insect attracting and capturing apparatus 1 according to the present embodiment, the insect capturing box 81 may have an adhesive sheet 90 that adheres the flying insect attracted by the suction fan device 40.
Therefore, by sticking the flying pest captured in the trapping box 81 to the adhesive sheet 90, the flying pest can be efficiently and surely removed.
　従って、本実施形態に係る飛翔害虫の誘引捕獲装置１によれば、飛翔害虫の捕獲効率を向上させた良好な誘引捕獲装置を提供できる。 Therefore, according to the flying insect attracting and capturing apparatus 1 according to the present embodiment, it is possible to provide a favorable attracting and capturing apparatus with improved flying insect capturing efficiency.
