[0010] The details of the pest trapping device 1 according to the present invention are as follows, with reference to the accompanying drawings. The following embodiments include not only essential features of the present invention, but also features that can be selectively adopted and features that can be appropriately combined. In addition, in Figs. 3, 4 and 6, a part of the outer peripheral surface that forms the outer shape of the device body 10 is omitted in order to show the inside of the pest trapping device 1.

[0011] First Embodiment 1 to 4, a pest trapping device 1 according to this embodiment has an up-down direction Y, a lateral direction X, and a front-rear direction Z that intersect with 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, 12 facing each other in the front-rear direction Z, top and bottom surfaces 13, 14 facing each other in the up-down direction Y, and first and second side surfaces 15, 16 facing each other in the lateral direction X.

[0012] The front surface 11 of the pest trapping device 1 is provided with a substantially circular front opening (attraction opening) 18 for allowing pests, such as mosquitoes 8, to enter the inside. An exhaust port 19b of a blowing means 19 is exposed on the outer surface of the rear surface 12. In the illustrated example, the device body 10 is a substantially rectangular parallelepiped, but may have any of various known three-dimensional shapes such as a triangular shape or a spherical shape. The front opening 18 may have any of various known shapes such as a triangular shape or a rectangular shape other than a substantially circular shape, and 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, black flies, horseflies, stable flies, etc. In this specification, a mosquito 8 that lives daily is given as an example.

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

[0015] The device body 10 further has a front region 21, a rear region 22, and an accommodation space S consisting of a front accommodation space S1 in the front and rear regions 21, 22 and a rear accommodation space S2 in the rear region. The boundary between the front region 21 and the rear region 22 is located toward the rear, and the length dimension of the front region 21 in the front-to-rear direction Z is 1.2 to 1.5 times the length dimension of the rear region 22 in the front-to-rear direction Z.

[0016] Further, on the rear side of the device body 10, there is disposed a blower means 19 located opposite the front opening 18 in the front-rear direction Z and generating a rearward air flow P1 within the storage space S. The blower 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 this embodiment, the front and rear regions 21, 22 of the device 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 known connecting means, for example, connecting means (not shown) consisting of an engaging claw and an engaging recess, and communicate with each other via a communication port 23 located at the internal boundary portion.

[0018] The device main body 10 includes a first attraction unit U1 having a function of attracting mosquitoes by light and airflow, and a second attraction unit U2 having a function of attracting mosquitoes by carbon dioxide and a fermented odor that mosquitoes like, as means for attracting mosquitoes into the accommodation space S. The first attraction unit U1 has an airflow generating section consisting of a blowing means 19 and an illumination section 30 having a light source 32, both of which are disposed in the accommodation space S, and the second attraction unit U2 has an attraction element generating section 51 located in the front region 21 and a heating section 52 for heating it.

[0019] The front area 21 has an illumination unit 30 located above and a base 40 located below. The illumination unit 30 has a top wall 31 located facing and spaced apart from the upper surface 13 of the device body 10 in the up-down direction Y, and a plurality of light sources 32 fixed to the top wall 31. The top wall 31 has a stepped portion located at the front, a flat portion extending rearward from the stepped portion, and an inclined portion extending rearward from the flat portion, gradually sloping upward.

[0020] The light source 32 may be an LED, a laser light emitting element, a fluorescent tube, or the like, and is preferably an LED. By arranging the lighting unit 30 above the front region 21, for example, when the device body 10 is placed in a dark place such as a campsite at night, the light of the light source 32 stands out and can function as an initial attraction means for luring mosquitoes outside the device body 10 into the inside through the front opening 18.

[0021] The base 40 has a front cover 41 that extends in a curved shape from the front surface to the rear and is preferably breathable, and a base body 45 located behind the front cover 41. The base body 45 has an air blowing means (auxiliary air blowing means) 46 located on the front side, and a second induction unit U2 located above the air blowing means 46.

[0022] A control unit 60 is disposed in the area surrounded by the air blowing means 46 and the underside of the second attraction unit U2. The control unit 60 has a circuit board including a CPU, memory, etc., and is driven by a power source provided by a power source unit 61 including a lithium battery located below the rear area 22, and transmits drive control signals to the lighting unit 30, the first attraction unit U1, the second attraction unit U2, etc. based on the detected open / closed state of a switch unit (not shown).

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

[0024] The attraction element generating unit 51 can generate an odor and carbon dioxide that have an attractive effect on mosquitoes by fermenting yeast. Fermentation is a process in which microorganisms such as yeast break down organic compounds to obtain energy, producing alcohols, organic acids, carbon dioxide, and the like. The fermentation in the present invention is preferably alcohol fermentation, and more preferably ethanol fermentation. Ethanol fermentation is a reaction in which yeast acts on sugars that can be utilized by yeast, such as glucose, fructose, and sucrose, to produce ethanol and carbon dioxide.

[0025] In the present embodiment, brewer's yeast (dry yeast) is reacted with blackstrap molasses to generate ethanol (EtOH) and carbon dioxide (CO2) in the attractant generating unit 51. In addition to sugars such as blackstrap molasses and yeasts such as brewer's yeast, the attractant generating unit 51 may also contain urea, fatty acids, fatty acid esters, and fatty acid aldehydes.

[0026] In this way, the carbon dioxide and fermentation odor generated by the ethanol fermentation using blackstrap molasses, which is also used in food, and beer yeast do not have any adverse effects on the human body, so the pest trapping device 1 can be used safely even near children and infants.In addition, since no toxic gases are generated even when the device is incinerated at the time of disposal, it can be disposed of safely.

[0027] When the heat generating unit 52 generates heat, the attractant element generating unit 51 located above is heated, and fermentation by the yeast is promoted. As a result, fermentation progresses and the yeast is heated to a living body temperature, and more ethanol, carbon dioxide, and yeast odor are generated than before heating, and these can be discharged into the storage space S from the upper opening 50a.

[0028] Pests such as mosquitoes and black flies like sweet and sour smells and alcoholic smells that are produced by the decomposition of plants by microorganisms, such as fermentation, decay, and fruit ripening, and therefore it can be said that they like the fermentation odor and the smell of evaporating ethanol generated by the attractant element generating unit 51.

[0029] In addition, blood-sucking insects such as mosquitoes have a high level of ability to detect carbon dioxide gas exhaled by humans, and can detect even a 0.01% change in the standby gas concentration, so the carbon dioxide generated from the attraction element generating unit 51 can be said to be 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 drive of the fans 46a is controlled by the control unit 60. The fans 46a are secondary, and take in outside air from the air holes 5, 6, and blow heat generated by the fermentation action of the attraction element generating unit 51 and heat generated around the control unit toward the front surface 11, and the resulting air flow P2 merges with the air flow P1 generated by the blowing means 19 and directed from the front to the rear.

[0031] As a result, the airflow P1 becomes warm air close to the optimum temperature for the living body, and the mosquitoes 8 can be attracted further backward.

[0032] In this embodiment, the heat generating unit 52 is controlled by the control unit 60, but it may be heated by a chemical reaction, as in a disposable warmer. In this case, it can be said that power consumption and manufacturing costs can be reduced.

[0033] The rear accommodation space S2 of the rear area 22 has a rear upper space and a rear lower space divided vertically by a separation wall 29. The rear upper space has a pest trapping section 70 located on the front area 21 side, and a blowing means (main blowing means) 19 located behind the pest trapping section 70.

[0034] The pest trapping section 70 has a plurality of adhesive sheets 72 housed in a net-shaped storage bag 71 that is open at the front side. The adhesive sheet 72 has an adhesive force capable of trapping mosquitoes, flies, etc., and has a base material made of synthetic resin, nonwoven fabric, paper, etc., and an adhesive applied to the base material. The material of the adhesive is not particularly limited, but examples of the adhesive include polyolefin-based polymer elastomers such as ethylene-propylene copolymer, polybutene, and polyisobutylene.

[0035] A sliding opening 73 that can be opened and closed is provided on the upper surface where the pest capturing part 70 is located, and after use, the mosquitoes captured on the adhesive sheet 72 can be removed from the opening 73 together with the storage bag 71 and discarded, and then immediately replaced with a new one.

[0036] The blowing means 19 is composed of a plurality of fans 19a aligned in the vertical direction Y, the drive of which is controlled by the control unit 60, and a dust collecting filter is disposed in front of the fans 19a.

[0037] When using the pest trapping device 1 of this embodiment, first, the power switch 2 is turned on and a control signal is sent from the control unit 60 to drive the lighting unit 30, the air flow generating unit consisting of the blowing means 19, 46, and the attraction element generating unit 51.

[0038] First, the light source 32 of the lighting unit 30 is turned on, causing mosquitoes outside to enter the inside of the device main body 10. Next, the air flow P1 generated by the air flow generating unit and the carbon dioxide and fermentation odor generated by the attraction element generating unit 51 and released into the storage space S from the upper opening 50a combine to attract the mosquitoes toward the back of the storage space S, i.e., toward the rear.

[0039] The attracted mosquitoes move through communication opening 23 in the boundary portion to pest trapping section 70, where they are captured on adhesive sheet 72. In this way, by combining a plurality of attractant elements consisting of lighting, air flow, carbon dioxide, and fermented odor, mosquitoes can be attracted to storage space S of device main body 10 more reliably and collected and trapped than, for example, devices that attempt to capture mosquitoes using only a light source such as an LED or devices that attempt to capture mosquitoes using only a fermented odor.

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

[0041] As another method to repel pests, mosquito coils and electric mosquito repellents are used, but mosquito coils are unsafe because they use fire, and electric mosquito repellents are difficult to carry around freely.

[0042] Furthermore, in recent years, infectious diseases caused by the bites of mosquitoes carrying pathogens such as dengue fever, chikungunya fever, Zika virus infection, Japanese encephalitis, and West Nile fever (mosquito-borne infectious diseases) have been reported to be prevalent in tropical and subtropical regions such as Central and South America and Asia, and have become a social problem. To prevent contracting these infectious diseases, it is important to avoid being bitten by mosquitoes that carry the infectious diseases.

[0043] The pest trapping device 1 according to the present invention can reliably capture and trap mosquitoes, thus solving this social problem. In addition, since the liquid agent containing the repellent is not directly sprayed or applied to the skin, the user does not develop allergies, and since it is rechargeable, it is highly portable and can be easily used in places without power sources, such as campsites and summer beer gardens.

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

[0045] In the pest trapping device 1 according to this embodiment, a plurality of electrode sections are arranged in the pest trapping section 80. The electrode sections are composed of a negative electrode plate 81 and a positive electrode plate 82 facing each other, and are electrically connected via an electric cord to a transformer arranged in a power supply section 61 that houses a lithium battery or the like.

[0046] When the power switch 2 is used to turn on the power, a high voltage is applied to the cathode plate 81 and anode plate 82 of the electrode unit. When a mosquito attracted to the insect trap unit 80 passes through the gap between the anode plate 81 and the cathode plate 82, insulation breakdown occurs, causing a current to flow through the mosquito and generating a discharge. The insect receives an electric shock from the discharge and falls to death by heat or burn. The falling mosquitoes are collected in a tray (not shown) located below the electrode unit.

[0047] The cathode plate 81 and anode plate 82 of the electrode portion have a mesh shape, and the mesh size becomes gradually smaller toward the rear. In this way, by making the mesh size gradually smaller, relatively large pests can be captured at the front side, and relatively small pests can be captured at the rear side. Also, the dimension in the up-down direction Y of the cathode plate 81 and anode plate 82 constituting the electrode portion gradually becomes larger toward the rear. With this configuration, the number of electrode portions located in front of the blowing means 19 is reduced, so that the obstruction of the flow of the air flow P1 caused by the electrode portions acting as a wall can be minimized.

[0048] In this way, the pest trapping section 80 can reliably capture and collect mosquitoes even by applying an electric shock.

[0049] The present invention can include at least the following embodiments, which can be adopted separately or in combination with each other. (1) The second attraction unit further has a lighting section located on the upper side within the forward area. (2) The second attraction unit further includes a heat generating portion located below the attraction element generating portion. (3) Blackstrap molasses and brewer's yeast are used for the fermentation of the attractant generating section. (4) The pest trapping portion has a plurality of adhesive sheets contained in a containing bag. (5) The pest trapping portion includes a plurality of electrode portions each having a negative electrode plate and a positive electrode plate. [Explanation of symbols]
