Modes for Carrying Out the Invention

[0010] Referring to the attached drawings, the details of the pest trapping device 1 according to the present invention will be described as follows. In addition, the following embodiments include, in addition to the essential requirements that the present invention cannot lack, optional requirements that can be adopted and requirements that can be appropriately combined. In FIGS. 3, 4, and 6, in order to show the inside of the pest trapping device 1, a part of the outer peripheral surface forming the outer shape of the device main body 10 is omitted.

[0011] <First Embodiment> Referring to FIGS. 1 to 4, the pest trapping device 1 according to the present embodiment has vertical direction Y, horizontal direction X, and front-rear direction Z that intersect each other, and includes a device main body 10. The device main body 10 has a substantially rectangular parallelepiped outer shape, and has front and rear surfaces 11 and 12 facing each other in the front-rear direction Z, upper and lower surfaces 13 and 14 facing each other in the vertical direction Y, and first and second side surfaces 15 and 16 facing each other in the horizontal direction X.

[0012] On the front surface 11 of the pest trapping device 1, a substantially circular front opening (attraction opening) 18 for allowing pests, for example, mosquitoes 8 to enter the inside is provided. In addition, the exhaust port 19b of the blowing means 19 is exposed on the outer surface of the rear surface 12. In the illustrated example, the device main body 10 is a substantially rectangular parallelepiped, but may have various known three-dimensional shapes such as a triangular shape and a spherical shape. In addition, the front opening 18 may have various known shapes other than a substantially circular shape, such as a triangular shape and a rectangular shape, or may be formed of a plurality of openings.

[0013] The pest trapping device 1 according to the present invention is a device for trapping pests indoors and outdoors, and the target pests are winged blood-sucking pests such as mosquitoes, midges, horseflies, and flesh flies. In this specification, the mosquitoes 8 that inhabit daily are exemplified.

[0014] On the first side surface 15 of the device main body 10, a power switch 2 and a USB port 4 for charging a rechargeable lithium battery housed inside are located, and on the second side surface 16, air holes 5 and 6 communicating with the inside are arranged side by side in the front-rear direction Z.

[0015] The apparatus main body 10 further has a storage space S including a front region 21, a rear region 22, a front storage space S1 within the front and rear regions 21, 22, and a rear storage space S2 within the rear region. The boundary portion between the front region 21 and the rear region 22 is located closer to the rear, and the length dimension of the front region 21 in the front-rear direction Z is 1.2 to 1.5 times the length dimension of the rear region 22 in the front-rear direction Z.

[0016] Also, on the rear surface side of the apparatus main body 10, there is disposed a blowing means 19 that is located opposite to the front opening 18 in the front-rear direction Z and generates an air flow P1 directed rearward within the storage space S. The blowing means 19 has a fan 19a located within the storage space S and an exhaust port 19b for discharging the air within the storage space S to the outside.

[0017] In the present embodiment, the front and rear regions 21, 22 of the apparatus main body 10 are formed by first and second cases 24, 25 that are separably connected to each other. The first and second cases 24, 25 are separably connected to each other via a known connecting means, for example, a connecting means (not shown) composed of an engaging claw and an engaging recess, and are communicated with each other via a communication port 23 located at the internal boundary portion.

[0018] The apparatus main body 10 includes a first attracting unit U1 having a function of attracting mosquitoes into the storage space S by light or an air flow, and a second attracting unit U2 having a function of attracting mosquitoes by carbon dioxide and a fermentation odor preferred by mosquitoes. The first attracting unit U1 has an air flow generating unit composed of the blowing means 19 and a lighting unit 30 having a light source 32, both disposed within the storage space S. The second attracting unit U2 has an attracting element generating unit 51 located in the front region 21 and a heat generating unit 52 for heating the attracting element generating unit 51.

[0019] The front area 21 has an illumination unit 30 positioned above and a base 40 positioned below. The illumination unit 30 has a ceiling wall 31 that is spaced apart and opposed to the upper surface 13 of the apparatus main body 10 in the vertical direction Y, and a plurality of light sources 32 fixed to the ceiling wall 31. The ceiling wall 31 has a stepped portion positioned in the front, a flat portion extending rearward from the stepped portion, and an inclined portion extending gradually upward from the flat portion toward the rear.

[0020] As the light source 32, an LED, a laser light emitting element, a fluorescent tube, etc. can be used, and preferably an LED is used. Since the illumination unit 30 is disposed above the front area 21, for example, when the apparatus main body 10 is placed in a dark place such as a campsite at night, the light of the light source 32 is prominent and can function as an initial attracting means for allowing mosquitoes outside the apparatus main body 10 to enter from the front opening 18 into the interior.

[0021] The base 40 has a front cover 41 that extends in a curved shape from the front to the rear and preferably has air permeability, and a base body 45 positioned behind the front cover 41. The base body 45 has a blowing means (sub-blowing means) 46 positioned on the front side and a second attracting unit U2 positioned above the blowing means 46.

[0022] A control unit 60 is disposed in the region surrounded by the blowing means 46 and the lower surface of the second attracting unit U2. The control unit 60 has a circuit board such as a CPU and a memory, is driven using a power supply unit 61 including a lithium battery positioned below the rear area 22 as a power source, and based on the detected open / closed state of a switch unit (not shown), sends drive control signals to the illumination unit 30, the first attracting unit U1, the second attracting unit U2, etc.

[0023] The second attracting unit U2 has an upper surface 50 having an upper opening 50a, and is box-shaped with front and rear surfaces, side surfaces, and a bottom surface, and inside has an attracting element generating unit 51 and a heating unit (heater) 52 positioned below the attracting element generating unit 51.

[0024] The attracting factor generating unit 51 can generate an odor and carbon dioxide that exhibit an attracting effect on mosquitoes through the fermentation of yeast. Fermentation is a process in which microorganisms such as yeast decompose organic compounds to obtain energy and produce alcohols, organic acids, carbon dioxide, etc. Fermentation in the present invention is preferably alcoholic fermentation, more preferably ethanol fermentation. Ethanol fermentation is a reaction in which yeast is allowed to act on sugars such as glucose, fructose, and sucrose that can be utilized by yeast to produce ethanol and carbon dioxide.

[0025] In the attracting factor generating unit 51 in the present embodiment, beer yeast (dry yeast) is allowed to act on molasses to produce ethanol (EtOH) and carbon dioxide (CO2). In addition to sugars such as molasses and yeasts such as beer yeast, urea, fatty acids, fatty acid esters, and fatty aldehydes may be blended in the attracting factor generating unit 51.

[0026] Thus, since the carbon dioxide and fermentation odor generated by ethanol fermentation using molasses and beer yeast, which are also used in food, do not have an adverse effect on the human body, the pest capturing device 1 can be safely used even near children and infants. Also, since no toxic gases are generated even when incinerated at the time of disposal, it can be safely disposed of.

[0027] When the heating unit 52 generates heat, the attracting factor generating unit 51 located above is heated, and the fermentation by yeast is promoted. As a result, the fermentation progresses, and it is heated to a biological temperature, and more ethanol, carbon dioxide, and the odor of yeast are generated than before heating, and can be allowed to flow out from the upper opening 50a into the accommodation space S.

[0028] Pests such as mosquitoes and midges prefer sweet and sour scents and alcohol scents generated by the decomposition of plants by microorganisms such as fermentation, decay, and fruit ripening. Therefore, it can be said that they prefer the fermentation odor generated by the attracting factor generating unit 51 and the odor of evaporating ethanol.

[0029] In addition, blood-sucking insects such as mosquitoes have a highly sensitive ability to detect the carbon dioxide exhaled by humans and can detect even a 0.01% change in the gas concentration during standby. Therefore, it can be said that the carbon dioxide generated from the attracting element generation unit 51 is an element that can attract mosquitoes.

[0030] The blowing means 46 is composed of a plurality of fans 46a arranged in the horizontal direction X. The driving of the fans 46a is controlled by the control unit 60. The fans 46a are secondary components. They take in outside air from the air holes 5 and 6, and blow the heat generated by the fermentation action of the attracting element generation unit 51 and the heat generated around the control unit toward the front surface 11 side, and the air flow P2 merges with the air flow P1 flowing from the front to the rear by the blowing means 19.

[0031] As a result, it can be said that the air flow P1 becomes warm air approaching the biocompatible temperature, and can attract the mosquitoes 8 further to the rear.

[0032] In this embodiment, the heat generating unit 52 is controlled by the control unit 60. However, for example, it may generate heat by a heat generating action due to a chemical reaction such as a disposable hand warmer. In this case, it can be said that power consumption and manufacturing costs can be suppressed.

[0033] The rear accommodation space S2 in the rear area 22 has an upper rear space and a lower rear space divided vertically via a partition wall 29. The upper rear space has a pest trapping unit 70 located on the front area 21 side and a blowing means (main blowing means) 19 located behind the pest trapping unit 70.

[0034] The pest trapping unit 70 has a plurality of adhesive sheets 72 accommodated in a net-shaped accommodation bag 71 with an open front side. The adhesive sheets 72 have an adhesive force capable of trapping mosquitoes, flies, etc., and have a base material formed from a synthetic resin, non-woven fabric, paper, etc., and an adhesive applied to the base material. The material of the adhesive is not particularly limited, and for example, polyolefin-based polymer elastomers such as ethylene-propylene copolymer, polybutene, and polyisobutylene can be considered.

[0035] On the upper surface portion where the pest capture unit 70 is located, there is a slidable opening 73 that can be opened and closed. After use, with mosquitoes captured on the adhesive sheet 72, the entire storage bag 71 can be taken out through the opening 73 and discarded, and can be immediately replaced with a new one.

[0036] The air blowing means 19 is composed of a plurality of fans 19a arranged in the vertical direction Y that are driven and controlled by the control unit 60, and a dust collection filter is arranged in front of them.

[0037] When using the pest capture device 1 according to this embodiment, first, turn on the power switch 2, and a control signal is transmitted from the control unit 60 to drive the lighting unit 30, the air flow generation unit composed of the air blowing means 19 and 46, and the attraction element generation unit 51.

[0038] First, when the light source 32 of the lighting unit 30 lights up, mosquitoes outside enter the inside of the device main body 10. Next, the air flow P1 generated by the air flow generation unit, and the carbon dioxide and fermentation odor generated by the attraction element generation unit 51 and discharged from the upper opening 50a into the storage space S combine to attract the mosquitoes toward the back side of the storage space S, that is, toward the rear.

[0039] The attracted mosquitoes move through the communication port 23 at the boundary portion to the pest capture unit 70, and are captured on the adhesive sheet 72 in the pest capture unit 70. In this way, by combining a plurality of attraction elements consisting of lighting, air flow, carbon dioxide, and fermentation odor, it is possible to surely attract mosquitoes into the storage space S of the device main body 10 and capture and collect them compared to a device that tries to capture mosquitoes only with a light source such as an LED or a device that tries to capture mosquitoes only with fermentation odor.

[0040] Here, as a method for repelling pests such as mosquitoes, flies, wasps, and mites, conventionally, a liquid agent containing a repellent has been directly sprayed or applied to the skin. However, the method of directly spraying or applying a liquid agent containing such a repellent to the skin may cause some people to inhale it through the mouth and choke, or may cause skin inflammation or allergic symptoms.

[0041] Also, as another method for repelling pests, mosquito coils and electric mosquito repellents are used. However, mosquito coils are not safe because they use fire, and electric mosquito repellents are difficult to carry around freely.

[0042] Furthermore, in recent years, it has been reported that infectious diseases (mosquito-borne infectious diseases) caused by being bitten by mosquitoes carrying pathogens such as dengue fever, chikungunya fever, Zika virus infection, Japanese encephalitis, and West Nile fever are prevalent in tropical and subtropical regions such as Central and South America and Asia, becoming a social problem. As a preventive measure to avoid contracting these infectious diseases, it is important not to be bitten by the mosquitoes that cause the infectious diseases.

[0043] According to the pest capture device 1 according to the present invention, mosquitoes can be reliably collected and captured, so that such a social problem can be solved. Also, since it does not directly spray or apply a liquid agent containing a repellent to the skin, it does not cause allergies in users. Furthermore, since it is rechargeable, it has excellent portability and can be easily used even in places without power such as camping sites and summer beer garden venues.

[0044] <Second Embodiment> Since the basic structure of the pest capture device 1 according to this embodiment is the same as that of the first embodiment, only the differences will be described below.

[0045] In the pest capturing device 1 according to this embodiment, a plurality of electrode parts are arranged in the pest capturing part 80. The electrode part is composed of a cathode plate 81 and an anode plate 82 facing each other, and is electrically connected via a transformer and an electric cord arranged in a power supply part 61 containing a lithium battery or the like.

[0046] When the power is turned on by the power switch 2, a high voltage is applied to the cathode plate 81 and the anode plate 82 of the electrode part. When a mosquito attracted to the pest capturing part 80 passes through the gap between the cathode plate 81 and the anode plate 82, dielectric breakdown occurs, a current flows through the mosquito, and discharge occurs. The insect that has received an electric shock due to the discharge is thermally or burned to death and falls. The fallen mosquitoes are accumulated in a tray (not shown) arranged below the electrode part.

[0047] The cathode plate 81 and the anode plate 82 of the electrode part have a mesh shape, and the mesh gradually becomes smaller toward the rear. In this way, by gradually reducing the mesh, relatively large pests can be captured on the front side, and relatively small pests can be captured on the rear side. In addition, the dimension in the vertical direction Y between the cathode plate 81 and the anode plate 82 constituting the electrode part gradually increases toward the rear. By having such a configuration, the number of electrode parts located in front of the air blowing means 19 is reduced, so that it is possible to minimize the obstruction of the flow of the air flow P1 by the electrode part acting as a wall.

[0048] In this way, mosquitoes can be surely captured and collected by electric shock in the pest capturing part 80.

[0049] The present invention described above can include at least the following embodiments. The embodiments can be adopted separately or in combination with each other. ( 1 ) For the fermentation action of the attracting element generating part, molasses and brewer's yeast are used. ( 2 ) The pest capturing part has a plurality of adhesive sheets housed in a storage bag. ( 3 ) The pest capturing part includes a plurality of electrode parts having a cathode plate and an anode plate.
