Description

本発明は、誘因ガスを揮発させて使用する送風機を有する捕虫装置の性能向上に関するものである。 The present invention relates to improving the performance of an insect catcher having a blower that volatilizes and uses an incentive gas.

従来この種の捕虫装置は、ケース内部に備えた誘引剤で誘引ガスを発生させて飛翔昆虫をケースの開口部周辺に誘引して、更に開口部からケース内部へ誘引して捕虫する構造が開示されていた（例えば、特許文献１参照）。 Conventionally, this type of insect catching device discloses a structure in which an attracting agent provided inside the case generates an attracting gas to attract flying insects around the opening of the case, and further attracts the flying insects from the opening to the inside of the case to catch the insects. (See, for example, Patent Document 1).

特開２００５−６５６３１号公報Japanese Unexamined Patent Publication No. 2005-65631

このような、従来の捕虫装置においては、誘引ガスの放出条件は常温揮発や送風蒸散が主であり、気温などの外部環境の変化により放出量が大きく変動していた。加熱による揮発を促進させるために、ヒーターで誘引剤を直接加熱しても、局所的な熱籠りや過熱が起こり、誘引剤の熱劣化を起こすこともあった。誘引剤が熱劣化を起こすと、誘引ガスは不安定に放出されて、捕虫効果が低いものになっていた。 In such a conventional insect catching device, the release conditions of the attracted gas are mainly room temperature volatilization and transpiration of blast, and the release amount fluctuates greatly due to changes in the external environment such as air temperature. Even if the attractant is directly heated with a heater in order to promote volatilization due to heating, local heat retention and overheating may occur, causing thermal deterioration of the attractant. When the attractant caused thermal deterioration, the attractant gas was released in an unstable manner, and the insect catching effect was low.

そこで本発明は、上記課題を解決するものであり、誘引剤の熱劣化を防止して、揮発した誘引ガスを装置周辺へ供給する捕虫装置を提供することを目的とする。 Therefore, the present invention solves the above-mentioned problems, and an object of the present invention is to provide an insect catching device that prevents thermal deterioration of the attractant and supplies volatilized attracting gas to the periphery of the device.

In the housing, a blower is arranged downstream of the suction port, and the first air outlet is provided with a drug storage unit capable of releasing a drug preferred by flying insects captured inside the housing. When the air sucked from the suction port by the blower is blown into the room from the first outlet and the second outlet, and out of the room from the outlet, a chemical is added to the air blown from the first outlet. An insect catching device that can be contained, in which a horizontal air passage from the back side of the housing to the drug storage portion is formed on the downstream side of the blower by a partition wall, and the horizontal air passage is formed.

本発明の請求項１に係る捕虫装置は、正面と背面を定めることができ、正面と背面を繋ぐ側面を有した筐体が形成され、前記筐体は、前記正面には該正面の中央部を含む吸込口と、前記吸込口に隣接させた第一吹出口を備え、前記背面には屋外へ連通させることができる排出口を備え、前記側面には第二吹出口を備え、前記筐体内において、前記吸込口の下流に送風装置を配置し、前記第一吹出口には前記筐体内側に捕獲する飛翔昆虫が好む薬剤を放出可能にして備えた薬剤貯留部を備え、前記送風装置によって前記吸込口から吸った空気を前記第一吹出口と第二吹出口から室内へ、前記排出口から室外へ吹出すときに、前記第一吹出口から吹き出す空気に薬剤を含有させることができる捕虫装置であって、前記筐体内において、前記送風装置の下流側に前記筐体の背面側から前記薬剤貯留部へ向かう水平風路を仕切り壁によって形成し、前記水平風路の中ほどは他の部分に比べて鉛直方向を狭めて風路断面積を小さくし、通過する空気を加熱する気流昇温部を配置し、前記水平風路の最下流に位置する前記薬剤貯留部の入り口は直前の風路の断面積よりも小さく形成したものである。 In the insect catching device according to claim 1 of the present invention, the front surface and the back surface can be defined, and a housing having a side surface connecting the front surface and the back surface is formed. A suction port including the above and a first outlet adjacent to the suction port are provided, a discharge port capable of communicating to the outside is provided on the back surface, and a second outlet is provided on the side surface of the housing. In the above, a blower is arranged downstream of the suction port, and the first outlet is provided with a drug storage unit capable of releasing a drug preferred by flying insects captured inside the housing, and is provided by the blower. When the air sucked from the suction port is blown into the room from the first outlet and the second outlet, and to the outside from the outlet, the air blown out from the first outlet can contain a chemical. In the device, a horizontal air passage from the back side of the housing to the drug storage portion is formed by a partition wall on the downstream side of the blower in the housing, and the middle of the horizontal air passage is another device. The vertical direction is narrowed compared to the portion to reduce the cross-sectional area of the air passage, an airflow temperature raising section for heating the passing air is arranged, and the entrance of the drug storage section located at the most downstream of the horizontal air passage is immediately before. It is formed smaller than the cross-sectional area of the air passage.

これにより、薬液貯留部へ供給される空気が、風路面積が狭められた気流昇温部で加熱され、その後広げられ、前記入り口で再び狭められて薬液貯留部内へ流入することとなるので、水平風路の中ほどにおいて、局所的な加熱で空気を均質に昇温でき、薬剤貯留部へは加熱後風路断面積が広がりその後に再び急縮小された風路を通過するので鉛直方向に乱流として薬剤を揮発させることができるため、薬剤の加熱の温度ムラを少なくし、高い揮発量が維持できる。 As a result, the air supplied to the chemical storage section is heated by the airflow heating section where the air passage area is narrowed, then expanded, narrowed again at the inlet, and flows into the chemical storage section. In the middle of the horizontal air passage, the air can be heated uniformly by local heating, and after heating, the cross-sectional area of the air passage expands to the drug storage part, and then it passes through the rapidly reduced air passage again, so it is in the vertical direction. Since the drug can be volatilized as a turbulent flow, the temperature unevenness of heating the drug can be reduced and a high volatilization amount can be maintained.

さらに、前記気流昇温部が発する熱が前記薬剤貯留部へ直接伝導することを防ぐことができるので、薬剤の局所的な昇温を防ぐことができ、誘引剤の熱劣化を防止して、揮発量を高く維持した誘引ガスを装置周辺へ供給する捕虫装置を提供することができる。 Further, since it is possible to prevent the heat generated by the airflow temperature rising section from being directly conducted to the drug storage section, it is possible to prevent the local temperature rise of the drug and prevent thermal deterioration of the attractant. It is possible to provide an insect catching device that supplies an attracting gas that maintains a high volatile amount to the periphery of the device.

また、請求項２に係る捕虫装置は、前記薬剤貯留部内に配置し、該薬剤貯留部内の温度を測定する温度測定部と、前記温度測定部の検知した温度に基づき前記薬剤貯留部に流入する空気を所定の温度に加熱する気流昇温部を備え、前記薬剤貯留部の薬剤を所定の温度で揮発させるものである。 Further, the insect catching device according to claim 2 is arranged in the drug storage unit and flows into the drug storage unit based on the temperature measuring unit for measuring the temperature in the drug storage unit and the temperature detected by the temperature measuring unit. It is provided with an airflow temperature raising section that heats air to a predetermined temperature, and volatilizes the drug in the drug storage section at a predetermined temperature.

これにより、所定温度に加熱された空気が薬剤貯留部に流れ薬剤の揮発を促進させるので、局所的な過熱を防ぐことができる。また、外気温に依存させないようにして揮発させた高濃度で安定した誘引物質を第一吹出口から放出することもできる。つまり、放出させる薬剤の量を外気温に依存させないようにして装置周辺へ供給する捕虫装置を提供することもできる。 As a result, the air heated to a predetermined temperature flows to the drug storage portion and promotes the volatilization of the drug, so that local overheating can be prevented. In addition, a high-concentration and stable attractant that has been volatilized without depending on the outside air temperature can be released from the first outlet. That is, it is also possible to provide an insect catching device that supplies the amount of the released drug to the periphery of the device so as not to depend on the outside air temperature.

また、請求項３に係る捕虫装置は、前記気流昇温部が気流の温度を３０度から４０度の範囲内に加熱できるものである。 Further, in the insect catching device according to claim 3, the airflow heating unit can heat the temperature of the airflow within the range of 30 to 40 degrees.

これにより、薬剤特に、乳酸が二量化ないし高分子化（ポリマー化）することを防止する、すなわち、誘引剤の熱劣化を防止することができる。また、気流の温度範囲を人体温ほどにすることで、蚊のレセプターに感受され装置に誘引されやすくすることもできる。 This makes it possible to prevent the drug, particularly lactic acid, from dimerizing or polymerizing (polymerizing), that is, preventing thermal deterioration of the attractant. In addition, by setting the temperature range of the air flow to about the human body temperature, it is possible to easily be perceived by the mosquito receptor and attracted to the device.

以下、本発明の実施の形態について図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施の形態１）
図１は、本実施の形態の捕虫装置１である。また図２は、捕虫装置１の設置状態における垂直断面図である。また、図３は、捕虫装置１の設置状態における平断面図である。各図に示すように、本実施の形態１の捕虫装置１は、屋内２と屋外３など空間を隔てる壁４などに設置する排気機能を備えた装置である。 (Embodiment 1)
FIG. 1 is an insect catching device 1 of the present embodiment. Further, FIG. 2 is a vertical cross-sectional view of the insect catching device 1 in an installed state. Further, FIG. 3 is a plan sectional view of the insect catching device 1 in an installed state. As shown in each figure, the insect catching device 1 of the first embodiment is a device having an exhaust function installed on a wall 4 or the like that separates a space such as an indoor 2 and an outdoor 3.

捕虫装置１の本体は、正面５と背面６を定めることができる筐体７であり、正面５と背面６を繋ぐ側面８を有している。図２に示すように、正面５は屋内側に背面６は屋外側に配置している。なお、本実施の形態において、側面８は天面と底面を含んでいる。 The main body of the insect catching device 1 is a housing 7 capable of defining the front surface 5 and the back surface 6, and has a side surface 8 connecting the front surface 5 and the back surface 6. As shown in FIG. 2, the front surface 5 is arranged on the indoor side and the back surface 6 is arranged on the outdoor side. In the present embodiment, the side surface 8 includes a top surface and a bottom surface.

図１に示すように、正面５には、正面５の中央部を含み、正面開口面積比率を３０％以上とし、配色を相対的に暗くした飛翔昆虫を捉える吸込口９と、吸込口９に隣接させた第一吹出口１０を備えている。 As shown in FIG. 1, the front surface 5 includes a central portion of the front surface 5, has a front opening area ratio of 30% or more, and has a suction port 9 for catching flying insects having a relatively dark color scheme, and a suction port 9. It is provided with an adjacent first outlet 10.

そして図２に示すように、背面６には筐体７の内部を屋外３へ連通させることができる排出口１８を備えている。側面８には屋内２へ開口させる第二吹出口１９を備えている。 As shown in FIG. 2, the back surface 6 is provided with a discharge port 18 capable of communicating the inside of the housing 7 to the outdoors 3. The side surface 8 is provided with a second outlet 19 that opens to the indoor 2.

筐体７内において、捕虫網１１と送風装置１２と薬剤貯留部１３と捕虫箱１４を備えている。捕虫網１１と送風装置１２は、吸込口９の下流側に設けている。薬剤貯留部１３は第一吹出口１０の上流側に設けている。 In the housing 7, an insect net 11, a blower 12, a drug storage unit 13, and an insect box 14 are provided. The insect catching net 11 and the blower device 12 are provided on the downstream side of the suction port 9. The drug storage unit 13 is provided on the upstream side of the first outlet 10.

また、吸込口９から捕虫網１１、送風装置１２、水平風路１５、薬剤貯留部１３、第一吹出口１０へと順番に流れる風路２０と、吸込口９から捕虫網１１、送風装置１２、排出口１８へと流れる風路２１と、吸込口９から捕虫網１１、送風装置１２、第二吹出口１９のへと流れる風路２２が形成されている。なお、捕虫網１１と送風装置１２の位置関係は、送風装置１２が上流側で捕虫網１１が下流側となっても捕虫装置１による気流の流れおよび捕虫効果には差異が生じない。 Further, the air passage 20 that flows in order from the suction port 9 to the insect net 11, the blower 12, the horizontal air passage 15, the drug storage unit 13, and the first outlet 10, and the insect net 11, the blower 12, and the exhaust from the suction port 9. An air passage 21 flowing to the outlet 18 and an air passage 22 flowing from the suction port 9 to the insect net 11, the blower device 12, and the second air outlet 19 are formed. Regarding the positional relationship between the insect catching net 11 and the blower device 12, even if the blower net 11 is on the upstream side and the insect catching net 11 is on the downstream side, there is no difference in the air flow and the insect catching effect by the insect catching device 1.

薬剤貯留部１３の上流側かつ送風装置１２の下流側の風路２０の一部は、仕切壁３０によって筐体７の背面側から薬剤貯留部１３へ向かう水平風路１５を形成している。 A part of the air passage 20 on the upstream side of the drug storage unit 13 and the downstream side of the blower device 12 forms a horizontal air passage 15 from the back side of the housing 7 to the drug storage unit 13 by the partition wall 30.

図４及び図５に示すように、水平風路１５内部には空気を昇温する昇温風路２６と気流昇温部２７を配置している。気流昇温部２７は昇温風路２６内部に配置するのが好ましい。また、昇温風路２６は水平風路１５に隔壁２８を設け、水平風路１５の他の部分に比べて断面積を小さくしている。また、気流昇温部２７は昇温風路２６を水平方向に横断する構造が好ましい。気流昇温部２７にはニクロム線などの電熱線、カーボンヒーター、セラミックヒーター、赤外線ヒーターなどの加熱作用のあるものを用いることが好ましい。捕虫装置１外への放熱を防ぐために気流昇温部２７は水平構造が良い。加熱効果を高めるため、コイルのような巻き形状、スリット形状、蛇腹形状などとしても良い。また、昇温風路２６と流入開口１７は水平風路１５内で隔離している。 As shown in FIGS. 4 and 5, a temperature-increasing air passage 26 for raising the temperature of air and an airflow temperature-increasing unit 27 are arranged inside the horizontal air passage 15. The airflow heating unit 27 is preferably arranged inside the heating air passage 26. Further, the temperature rising air passage 26 is provided with a partition wall 28 in the horizontal air passage 15 so that the cross-sectional area is smaller than that of other parts of the horizontal air passage 15. Further, the airflow temperature raising unit 27 preferably has a structure that crosses the temperature rising air passage 26 in the horizontal direction. It is preferable to use a heating wire such as a nichrome wire, a carbon heater, a ceramic heater, an infrared heater, or the like having a heating action for the air flow heating unit 27. The airflow temperature raising unit 27 has a good horizontal structure in order to prevent heat dissipation to the outside of the insect catching device 1. In order to enhance the heating effect, a coil-like winding shape, a slit shape, a bellows shape, or the like may be used. Further, the temperature rising air passage 26 and the inflow opening 17 are separated in the horizontal air passage 15.

図３及び図４に示すように、薬剤貯留部１３は箱体であり、第一吹出口１０に合致させた流出開口１６と薬剤貯留部１３内に送風装置１２から送られた空気を取入れる流入開口１７を備えている。薬剤貯留部１３と水平風路１５は流入開口１７で接続されており、水平風路１５の鉛直断面の内部に流入開口１７が位置する。 As shown in FIGS. 3 and 4, the drug storage unit 13 is a box body, and the air sent from the blower 12 is taken into the outflow opening 16 and the drug storage unit 13 that match the first outlet 10. The inflow opening 17 is provided. The drug storage unit 13 and the horizontal air passage 15 are connected by an inflow opening 17, and the inflow opening 17 is located inside the vertical cross section of the horizontal air passage 15.

薬剤貯留部１３に関して、このましくは流入開口１７の開口面積が流出開口１６の開口面積に比べて小さく形成することが良い。例えば、流入開口１７は流出開口１６に比べて高さ方向を低くしたスリット状に形成することができる。薬剤貯留部１３に設置する薬剤は、乳酸、ドライアイスなどの二酸化炭素発生要素、アンモニア、オクテノール等の、蚊を誘引するのに一定の効果があるとされている成分を用いるとよい。薬剤貯留部１３に設置した薬剤は、流入開口１７から高い速度で流入する気流で揮発、拡散が促進され、開口面積の大きい流出開口１６から薬剤が広範囲に広がる。また、流出開口１６の開口面積を流入開口１７の開口面積に比べて大きく形成しているので、薬剤が噴出する速度が低下するので吸込口９に接近した飛翔昆虫の飛翔を阻害しない。気流が高速で流出すると飛翔昆虫を遠ざけるので好ましくない。 Regarding the drug storage portion 13, it is preferable that the opening area of the inflow opening 17 is made smaller than the opening area of the outflow opening 16. For example, the inflow opening 17 can be formed in a slit shape having a lower height direction than the outflow opening 16. As the drug installed in the drug storage unit 13, it is preferable to use a carbon dioxide generating element such as lactic acid and dry ice, and a component such as ammonia and octenol which is said to have a certain effect in attracting mosquitoes. The drug installed in the drug storage unit 13 is promoted to volatilize and diffuse by the air flow flowing in from the inflow opening 17 at a high speed, and the drug spreads over a wide range from the outflow opening 16 having a large opening area. Further, since the opening area of the outflow opening 16 is formed larger than the opening area of the inflow opening 17, the speed at which the drug is ejected is reduced, so that the flight of flying insects approaching the suction port 9 is not hindered. It is not preferable if the airflow flows out at high speed because it keeps flying insects away.

送風装置１２は、風洞２３と、風洞２３内に備えた羽根車２４とモータ２５とからなり、モータ２５からの動力を羽根車２４に伝え、羽根車２４が回転することで気流を発生させるものである。羽根車２４はシロッコファン、ターボファン、プレートファン、クロスフローファン、プロペラファンのようにいくつかの種類があり、本発明にはいずれにも適用可能であるが、ここではプロペラファンを用いる。羽根車２４は明度５以下が好ましい。飛翔昆虫が黒色を生物と認識し、誘引されるためである。また、正面５と背面６と側面８は明度５より大きい値が好ましく、吸込口９と風洞２３内部は明度５以下が好ましい。これにより飛翔昆虫は明暗を認識し易くなり、黒色側への誘引精度が向上するためである。 The blower 12 includes a wind tunnel 23, an impeller 24 provided in the wind tunnel 23, and a motor 25. The power from the motor 25 is transmitted to the impeller 24, and the impeller 24 rotates to generate an air flow. Is. There are several types of impellers such as a sirocco fan, a turbo fan, a plate fan, a cross flow fan, and a propeller fan, and all of them can be applied to the present invention, but a propeller fan is used here. The impeller 24 preferably has a brightness of 5 or less. This is because flying insects recognize black as a living thing and are attracted to it. Further, the front surface 5, the back surface 6, and the side surface 8 preferably have a brightness greater than 5, and the suction port 9 and the inside of the wind tunnel 23 preferably have a brightness of 5 or less. This makes it easier for flying insects to recognize light and darkness, and improves the accuracy of attracting to the black side.

上記構成により、送風装置１２を動作させると、送風装置１２から発生する気流は、吸込口９から捕虫装置１内部に流入し、一部の気流は水平風路１５や薬剤貯留部１３などを通った第一吹出口１０及び第二吹出口１９から屋内２に流出され、また別の一部の気流が排出口１８から屋外に流出される。 According to the above configuration, when the blower device 12 is operated, the airflow generated from the blower device 12 flows into the insect catching device 1 from the suction port 9, and a part of the airflow passes through the horizontal air passage 15, the drug storage unit 13, and the like. The first air outlet 10 and the second air outlet 19 flow out to the indoor 2, and another part of the air flow flows out from the discharge port 18 to the outside.

以下、風路２０の気流について記載する。 Hereinafter, the airflow of the air passage 20 will be described.

風路２０を流れる気流は、送風装置１２の下流側で、水平風路１５へ流入する。水平風路１５を通過する空気は、気流昇温部２７で加温される。昇温風路２６は水平方向には気流昇温部２７があり、ムラなく加温でき、隔壁２８設けたことによって、鉛直方向の風路高さ小さく、伝熱しやすくなっている。これにより、通過した空気を均質な加温空気とすることができる。 The airflow flowing through the air passage 20 flows into the horizontal air passage 15 on the downstream side of the blower device 12. The air passing through the horizontal air passage 15 is heated by the airflow heating unit 27. The temperature-increasing air passage 26 has an airflow temperature-increasing portion 27 in the horizontal direction and can be heated evenly. By providing the partition wall 28, the height of the air passage in the vertical direction is small and heat can be easily transferred. As a result, the passed air can be made into homogeneous heated air.

昇温風路２６を通過した空気は一度、水平風路１５内で、鉛直方向に広げられた後に、流入開口１７を通過する。流入開口１７は、水平風路１５よりも風路断面積が小さいので、空気は急縮小され、通過気流は鉛直方向への乱流として、薬剤貯留部１３に到達する。つまり、薬剤貯留部１３に到達する空気は、均質に昇温され、水平方向への気流乱れが少なく、鉛直方向への気流乱れが大きいものとなる。薬剤貯留部１３の薬剤は加温された空気により、揮発量が増加する。さらに鉛直方向への気流乱れがあるため、薬剤液面の分子拡散を促進することができ、揮発量が増加する。 The air that has passed through the temperature-increasing air passage 26 once spreads in the horizontal air passage 15 in the vertical direction, and then passes through the inflow opening 17. Since the inflow opening 17 has a smaller air passage cross-sectional area than the horizontal air passage 15, the air is rapidly reduced, and the passing airflow reaches the drug storage unit 13 as a turbulent flow in the vertical direction. That is, the air reaching the drug storage unit 13 is uniformly heated, the airflow turbulence in the horizontal direction is small, and the airflow turbulence in the vertical direction is large. The amount of the drug in the drug storage unit 13 is increased by the heated air. Furthermore, since there is airflow turbulence in the vertical direction, molecular diffusion on the chemical liquid surface can be promoted, and the amount of volatilization increases.

この一連の昇温過程において、薬剤が直接加熱されることは無く、気流昇温部２７から隔離もされ、昇温空気と接した薬剤から揮発を促しているため、薬剤自身の温度が大きく上昇することがない。これにより、薬剤の変質を防ぐことができる。例えば、乳酸は液粘度が高く、分子拡散速度が遅いため熱伝導しにくく、局所的に加熱されると熱だまりができる。そして乳酸は高温になると二量化や高分子化（ポリマー化）が促進され変質し、蚊の誘引効果を失う。本発明は上記作用を防ぎつつ、誘因ガスの揮発量を上昇させることができる。 In this series of heating process, the chemical is not directly heated, is isolated from the airflow heating unit 27, and promotes volatilization from the chemical in contact with the heated air, so that the temperature of the chemical itself rises significantly. There is nothing to do. As a result, deterioration of the drug can be prevented. For example, lactic acid has a high liquid viscosity and a slow molecular diffusion rate, so that it is difficult to conduct heat, and when it is locally heated, a heat pool is formed. When the temperature of lactic acid becomes high, dimerization and polymerization (polymerization) are promoted and the lactic acid deteriorates, and loses the effect of attracting mosquitoes. The present invention can increase the volatilization amount of the incentive gas while preventing the above action.

さらに昇温風路２６内部に気流昇温部２７を設けることで、昇温風路２６以外への伝熱を防ぐことができるので、捕虫装置１全体が加温されるエネルギーロスを防ぐ。また、吸込口９を通過した空気を全て加温することなく一部を第二吹出口１９から放出させるため、薬剤揮発に不要な空気への加温を防ぎ、昇温エネルギーを最小化し、かつ室温上昇を防ぐことで快適性を損なうことを防ぐ。 Further, by providing the airflow heating unit 27 inside the heating air passage 26, it is possible to prevent heat transfer to other than the heating air passage 26, so that energy loss in which the entire insect catching device 1 is heated is prevented. Further, since a part of the air passing through the suction port 9 is discharged from the second outlet 19 without being heated, heating of the air unnecessary for chemical volatilization is prevented, the heating energy is minimized, and the temperature rise energy is minimized. Preventing the room temperature from rising prevents the comfort from being impaired.

揮発した薬剤は第一吹出口１０から放出される。第一吹出口１０は吸込口９と同面の正面５に設置され、かつ隣接しているために流出した薬剤は、第一吹出口１０で広く噴出した後に、一部は吸込口９に流れ、一部は第一吹出口１０から屋内２側に濃度勾配を付けながら拡散する。 The volatilized drug is released from the first outlet 10. Since the first outlet 10 is installed on the front surface 5 on the same surface as the suction port 9 and is adjacent to the first outlet 10, the drug that has flowed out is widely ejected at the first outlet 10 and then partly flows to the suction port 9. , A part of it diffuses from the first outlet 10 to the indoor 2 side with a concentration gradient.

飛翔昆虫は、薬剤の濃度勾配に誘引され、捕虫装置１に近づき、最も高濃度な吸込口９ないし第一吹出口１０に接近する。その後黒色に引き付けられ、吸込口９内部ないし羽根車２４を目掛けて飛翔することで、送風装置１２によって吸込み気流のある吸込口９から吸引され、捕虫網１１に捕獲される。 The flying insects are attracted to the concentration gradient of the drug, approach the insect catching device 1, and approach the suction port 9 to the first outlet 10 having the highest concentration. After that, it is attracted to black and flies toward the inside of the suction port 9 or the impeller 24, and is sucked from the suction port 9 having a suction air flow by the blower 12 and captured by the insect net 11.

また、捕虫網１１を設けることで、吸込口９から侵入する飛翔昆虫を捕獲し、下流側に通さないことが可能となる。これにより、捕虫網１１より下流にある送風装置１２や捕虫装置１内部を蚊が通過することを防ぎ、内部の汚染を防ぐことでメンテナンス性や操作性を改善することでできる。なお、捕虫網１１に殺虫成分などを付着または含有させることで、捉えた飛翔昆虫を直接弱らせ、捕虫網１１から再飛翔することを防ぎ、かつ重力落下により捕虫網１１から落下させることで捕虫網１１の目詰まりを防ぐことができる。 Further, by providing the insect net 11, it is possible to capture the flying insects invading from the suction port 9 and prevent them from passing to the downstream side. As a result, it is possible to prevent mosquitoes from passing through the inside of the blower device 12 and the insect catching device 1 downstream from the insect catching net 11, and to prevent internal contamination, thereby improving maintainability and operability. In addition, by adhering or containing an insecticidal component or the like on the insect net 11, the captured flying insects are directly weakened to prevent re-flying from the insect net 11, and by dropping from the insect net 11 by gravity drop, the insect net 11 It is possible to prevent clogging.

本実施の形態では、図１及び図２において、第二吹出口１９は、天面を除く側面８に設けた例を示している。加えて天面に設けてもよい。 In the present embodiment, in FIGS. 1 and 2, the second outlet 19 is provided on the side surface 8 excluding the top surface. In addition, it may be provided on the top surface.

また、図２に示すように、捕虫網１１の下方に捕虫箱１４を設けることができる。捕虫箱１４は、捕虫網１１から落下する飛翔昆虫を受けるために、上方を開放させている。屋内２側から捕虫箱１４を引き出せる構造であると、捕獲した飛翔昆虫の死骸を容易に廃棄できる。 Further, as shown in FIG. 2, an insect trap box 14 can be provided below the insect net 11. The insect box 14 is open upward to receive flying insects falling from the insect net 11. If the structure is such that the insect trap box 14 can be pulled out from the indoor 2 side, the dead bodies of the captured flying insects can be easily discarded.

これにより、捕虫箱１４に捕獲した飛翔昆虫を貯めることができ、メンテナンス時には、屋内２側から捕虫箱１４を取り出して、内部の飛翔昆虫を捨てるだけで良い。 As a result, the flying insects captured can be stored in the insect catching box 14, and at the time of maintenance, it is sufficient to take out the insect catching box 14 from the indoor 2 side and discard the flying insects inside.

（実施の形態２）
本実施の形態では、捕虫装置１周りの外気温度に依存せず、薬剤揮発量をより安定化する構成を説明する。 (Embodiment 2)
In the present embodiment, a configuration that further stabilizes the amount of the drug volatilized without depending on the outside air temperature around the insect trapping device 1 will be described.

以下、図６及び図７を用いて説明する。
薬剤貯留部１３内の温度を測定する温度測定部２９と、温度測定部の検知した温度に基づき、気流昇温部２７の加熱量を調節する制御部３１を備えている。 Hereinafter, a description will be given with reference to FIGS. 6 and 7.
A temperature measuring unit 29 that measures the temperature inside the drug storage unit 13 and a control unit 31 that adjusts the heating amount of the airflow temperature raising unit 27 based on the temperature detected by the temperature measuring unit are provided.

温度測定部２９は、薬剤貯留部１３内に設ける。温度測定部２９の測定部分は熱電対、抵抗温度計、放射温度計などを用いることができる。 The temperature measuring unit 29 is provided in the drug storage unit 13. A thermocouple, a resistance thermometer, a radiation thermometer, or the like can be used as the measuring portion of the temperature measuring unit 29.

制御部３１は、温度測定部２９信号を受けて、温度測定部２９を制御する。アルゴリズムを備えている。 The control unit 31 receives the temperature measurement unit 29 signal and controls the temperature measurement unit 29. It has an algorithm.

すなわち、捕虫装置１の運転を判定し（Ｓ１）、温度測定を行う（Ｓ２）、測定温度が３０度以上であるか判定し（Ｓ３）、Ｎｏであれば気流昇温部２７を稼働させ（Ｓ４）再度Ｓ２を行い、Ｙｅｓであれば４０度以下であるか判定し（Ｓ５）、Ｎｏであれば気流昇温部２７を停止し（Ｓ６）再度Ｓ２を行い、Ｙｅｓであれば温度測定を一次停止する（Ｓ７）、その後、捕虫装置１の停止を判定し（Ｓ８）、Ｎｏであれば再度Ｓ２を行い、Ｙｅｓであれば制御を終えるものである。 That is, the operation of the insect catching device 1 is determined (S1), the temperature is measured (S2), it is determined whether the measured temperature is 30 degrees or higher (S3), and if No, the airflow temperature raising unit 27 is operated (S). S4) Perform S2 again, if Yes, determine whether the temperature is 40 degrees or less (S5), if No, stop the airflow temperature riser 27 (S6), perform S2 again, and if Yes, measure the temperature. After the primary stop (S7), the stop of the insect catching device 1 is determined (S8), if No, S2 is performed again, and if Yes, the control is finished.

温度測定部２９が検出する温度を規定温度範囲として３０〜４０度とすることで、体温に近い温度となり、この温度が蚊を誘引する要件の一つになり、捕虫性能を向上させることができる。 By setting the temperature detected by the temperature measuring unit 29 to 30 to 40 degrees as the specified temperature range, the temperature becomes close to the body temperature, and this temperature becomes one of the requirements for attracting mosquitoes, and the insect catching performance can be improved. ..

上記により、捕虫装置１周りの外気温度に依存せず、一定範囲内の昇温及び薬剤揮発量に制御することができる。つまり、高い蚊誘引性能を維持し、薬剤の変質や揮発多過を防ぐことができる。 According to the above, it is possible to control the temperature rise within a certain range and the amount of chemical volatilization without depending on the outside air temperature around the insect catching device 1. That is, it is possible to maintain high mosquito attracting performance and prevent deterioration of the drug and excessive volatilization.

伝染病を媒介する蚊などの飛翔昆虫に対して、薬剤を揮発して誘引除去する捕虫装置として有用である。 It is useful as an insect catching device that volatilizes and attracts and removes chemicals against flying insects such as mosquitoes that transmit infectious diseases.
