Description

insect trap

[0001] The present invention relates to an insect trap that attracts insects with an attracting light and traps them with an insect trapping sheet.

[0002] For example, the insect trap described in Patent Document 1 is equipped with an attracting light and an insect trapping sheet inside a case, and discloses a configuration in which the attracting light attracts insects such as gnats, flies, and moths, and the sticky insect trapping sheet traps the insects.

[0003] Japanese Patent Application Laid-Open No. 2006-230258

[0004] In the insect trap described in Patent Document 1, the space housing the attractant light was not completely sealed by the insect trapping sheet, so there were cases where many dead insects were found around the attractant light, making cleaning difficult. Furthermore, insects would adhere to the attractant light, causing the attractant light to become dirty and reducing the efficiency of ultraviolet radiation. Furthermore, if many insects were caught on the insect trapping sheet, the sheet would become distorted, causing problems with ultraviolet transmission. Furthermore, the insect trapping sheet, which is coated with adhesive, was not easy to attach or remove.

[0005] To provide an insect trap which has been devised in view of the above points and which can firmly attach an insect trapping sheet while keeping it flat, is easy to attach and detach, and prevents insects from coming into contact with an LED array.

[0006] The insect trap of the first aspect of the present invention comprises an installation base, a two-part case erected on the installation base and defining a vertically long dome space, the case including a rear case half and a front case half having a plurality of insect entry holes in a required arrangement and which is removable or can be opened to one side in a horizontal plane, an LED array provided inside the rear case half and emitting ultraviolet rays forward to attract insects, an insect trapping sheet which is a disposable item made of a transparent sheet coated on one side with an adhesive that captures insects, the insect trapping sheet being removably attached and separating the rear case half in an airtight manner with the adhesive facing toward the front case half, and a power supply means for supplying power to the LED array.

[0007] The insect trap of the second aspect of the present invention has the same configuration as the first aspect of the invention, but in addition, the peripheral edge of the insect trapping sheet is clamped between a first square frame member provided on the rear case half and a second square frame member provided on the front case half.

[0008] The insect trap of the third aspect of the present invention has the same configuration as the second aspect of the invention, but in addition, the insect trapping sheet has locking holes at the four corners, and these locking holes are fitted onto locking pins protruding from either the first square frame member or the second square frame member.

[0009] The insect trap of the fourth aspect of the present invention has the same configuration as the second aspect of the invention, but is configured such that the first square frame member or the second square frame member equipped with the latching pin is removably mounted on the rear case half or the front case half.

[0010] The insect trap of the fifth aspect of the present invention has the same configuration as the first aspect of the invention, but the LED array is configured by arranging multiple LEDs of one type or multiple types of LEDs that emit wavelengths of 365, 375, 385, 395, and 405 nm.

[0011] The insect trap of a sixth aspect of the present invention has the same configuration as the second aspect of the invention, but the LED array further includes at least one LED that emits visible light wavelengths.

[0012] The insect trap of the seventh aspect of the present invention has the same configuration as the first aspect of the invention, but the wiring board of the LED array is supported on the rear half case via a bracket or attached to a support erected on the installation base.

[0013] The insect trap of the eighth aspect of the present invention has the same configuration as the first aspect of the invention, but the power supply means has a plug that is electrically connected to a 100 or 200 volt general power outlet, and a step-down circuit that steps down the voltage of the current taken in from the plug to the required low voltage.

[0014] The insect trap according to a ninth aspect of the present invention has the same configuration as the fifth aspect of the present invention, and further has a configuration in which the power supply means supplies power to the LED array via the plug and the step-down circuit.

[0015] The insect trap of the tenth aspect of the present invention has the same configuration as the fifth aspect of the invention, but the power supply means includes a storage battery that is arranged to fit within the installation base, which is formed in a box shape, or inside the rear case half.

[0016] The insect trap of an eleventh aspect of the present invention has the same configuration as the first aspect of the invention, except that the storage battery is one of a lithium titanate battery (SCiB), an all-solid-state battery, and a magnesium-sulfur secondary battery.

[0017] The insect trap according to a twelfth aspect of the present invention has the same configuration as the tenth aspect of the present invention, but further includes a solar power generation panel as a power generation means for storing electricity in the storage battery.

[0018] The insect trap of the thirteenth aspect of the present invention has the same configuration as the tenth aspect of the invention, and is configured such that power is supplied from the storage battery to the LED array by a switch provided on an appropriate outer surface of the rear half case, or by a light sensor that detects the amount of light as it gets darker in the evening and turns on the power.

[0019] The insect trap of the fourteenth aspect of the present invention has the same configuration as the first aspect of the invention, but the adhesive contains an odorous component that insects like, or an application agent containing an odorous component that insects like is applied to at least a portion of the trap.

[0020] The insect trap of the fifteenth aspect of the present invention has, in addition to the configuration of the first aspect of the invention, an odorant storage section that stores and seals an odorant that emits an odor that insects like within the front half of the case, so that the odor that emits the odor that insects like is diffused within the front half of the case.

[0021] The insect trap according to a fourth aspect of the present invention has the same structure as the first aspect of the present invention, but further has a black coating formed on the outer surface of the front case half.

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0025] 1(A) and 1(B), an insect trap 1 according to an embodiment of the present invention includes a mounting base 2, a case 3 consisting of a rear case half 3a and a front case half 3b erected on the mounting base 2, an LED array 5 and an insect trapping sheet 6 provided within the case 3, and power supply means 7 for supplying power to the LED array 5. The mounting base 2 and the case 3 are made of stainless steel, galvanized iron, tinplate, aluminum, or plastic.

[0026] [Installation Table 2] The installation table 2 is, for example, a disk-shaped table with an outer diameter of 400 mm, which allows stable contact with the ground. The installation table 2 may also be, for example, a square plate with rounded corners.

[0027] [Case 3] The case 3 has a rear case half 3a fixed upright on the installation base 2, and a front case half 3b connected to the rear case half 3a at one side edge with multiple hinges 3c so that it can be opened in one direction. A handle 3d is provided on the top of the rear case half 3a.

[0028] The size of the cylindrical dome shape formed by closing the rear case half 3a and the front case half 3b together is preferably an outer diameter of 200-300 mm and a height of 900-1300 mm, which is an easy-to-carry size. Note that the shape may also be a square cylindrical dome, for example.

[0029] Note that instead of the multiple hinges 3c as the connecting means, a combination of hooks and locking holes may be used, for example. Specifically, hooks may be provided at the top and bottom four corners of the mating surface of the rear case half 3a, and locking holes that engage with the hooks may be provided at the top and bottom four corners of the mating surface of the front case half 3b, so that when the front case half 3b is lifted and the mating surfaces are lowered to a position slightly higher than the rear case half 3a, the locking holes engage with the hooks, and when the front case half 3b is lifted from the engaged state, the locking holes disengage from the hooks.

[0030] [Rear Case Half 3a] As shown in Figures 2(A), (B), and (C), rear case half 3a has a rear semi-cylindrical portion 3a1, a semicircular top surface portion 3a2 and a bottom surface portion 3a3 that are provided to close the upper and lower ends of rear semi-cylindrical portion 3a1, and a first rectangular frame member 3a4 that is provided to connect both side edges of rear semi-cylindrical portion 3a1, and has latch pins 3a7 that protrude forward from the upper and lower four corners of first rectangular frame member 3a4.

[0031] As shown in FIG. 1B, in this embodiment, in order to secure a large space for accommodating the LED array 5, the shape is a super-semi-cylindrical shape, which is a cylindrical surface having a required larger central angle than a semi-cylindrical surface.

[0032] The bottom surface portion 3a3 is fixed onto the installation base 2. The bottom surface portion 3a3 has a screw through hole (no reference numeral) through which a tapping screw 3a5 is passed and further threaded into a screw hole (no reference numeral) formed in the installation base 2, thereby fixing the rear case half 3a to the installation base 2. Note that the rear case half 3a may be fixed to the installation base 2 by welding or another assembly structure.

[0033] [Front case half 3b] As shown in Figure 1 (B) , the front case half 3b has a front semi-cylindrical portion 3b1 and a second rectangular frame member 3b2 in the shape of a rectangular frame that is provided to connect both side edges of the front semi-cylindrical portion 3b1, and the second rectangular frame member 3b2 has locking holes 3b3 at the top and bottom four corners that fit over the locking pins 3a7 protruding from the four corners of the first rectangular frame member 3a4 described above.

[0034] As shown in FIG. 4A, the upper end of the front case half 3b coincides with the upper end of the rear semi-cylindrical portion 3a1 of the rear case half 3a, and the lower end has a gap of 2-3 mm between it and the upper surface of the installation base 2, so that it does not interfere with the installation base 2 when opening or closing.

[0035] As shown in Fig. 1(A), the radius of curvature of the front semi-cylindrical portion 3b1 is 3-5 mm larger than that of the rear semi-cylindrical portion 3a1 of the rear case half 3a, and one edge of the front semi-cylindrical portion 3b1 opposite to the side where the hinge 3c is provided overlaps the outside of the rear semi-cylindrical portion 3a1 of the rear case half 3a by, for example, a width of 20 mm. As shown in Fig. 1(B), a pair of magnetic locks 3a6, 3b4 are provided on both sides of the overlapping portion as locking means, and the pair of magnetic locks 3a6, 3b4 hold the front case half 3b closed relative to the rear case half 3a.

[0036] It is preferable that the outer surface of the front case half 3b is coated with a black paint film to attract insects.

[0037] 1(A) and 1(B), multiple insect entry holes 4 are provided over substantially the entire surface of the front semi-cylindrical portion 3b1. In this embodiment, the insect entry holes 4 are vertically elongated holes arranged in a regular row, but they may also be arranged in a diagonal row, and may have any suitable shape, such as a circle, a horizontally elongated hole, an ellipse, a triangle with rounded corners, or a rectangle. The insect entry holes 4 may be of any size that allows the entry of insects such as moth flies, midges, flea flies, fruit flies, small flies, winged insects, moths, and stink bugs. The front case half 3b has an open top end, which allows insects to enter through.

[0038] [LED Array 5] As shown in FIG. 3, the LED array 5 has three vertical rows of LEDs 5a arranged on the surface of a wiring board 5b. FIG. 3 shows the wiring surface of the wiring board 5b, illustrating the wiring positions of the LEDs 5a. As shown in FIGS. 2A, 2B, 2C, and 4A, the wiring board 5b has brackets 5c and 5d fixed at its lower and upper ends with tapping screws 5e and 5f. The lower bracket 5c is fixed to the bottom surface 3a3 of the rear case half 3a with a tapping screw 5g, and the upper bracket 5d is fixed to the inner surface of the rear semi-cylindrical portion 3a1 of the rear case half 3a with a tapping screw 5h, thereby erecting the LED array 5 within the rear case half 3a. Alternatively, a support (not shown) may be provided to extend from the installation base 2 and be erected within the rear case half 3a, and the LED array 5 may be attached to the support.

[0039] The LED array 5 in this embodiment has three vertical rows of LEDs 5a, but is not limited to this. For example, it may have one vertical row, five vertical rows, or a diagonal row. Furthermore, LEDs emitting different wavelengths may be arranged in each vertical row, or multiple types of LEDs emitting different wavelengths may be arranged in a vertical row, or multiple types of LEDs emitting different wavelengths may be arranged separately.

[0040] The LEDs 5a constituting the LED array 5 are limited to those that emit ultraviolet wavelengths of 365, 375, 385, 395, and 405 nm. The ultraviolet rays emitted from the LED array 5 are emitted to the outside through the insect entry hole 4 provided in the front case half 3b. The reason for limiting the type to this is that this wavelength range does not cause harm to the human eye when irradiated with ultraviolet rays, and because this is the only type of LED currently available on the market that covers this wavelength range. Currently available LEDs emit deep ultraviolet rays with wavelengths of 235, 255, 265, 275, 280, 285, 300, 310, 325, and 340 nm, but these are not recommended because they can cause harm to the human eye when irradiated through the insect entry hole 4.

[0041] For the LED array 5, even if LEDs with a wavelength of 365 nm and LEDs with a wavelength of 405 nm are provided, it is not possible to synthesize the intermediate wavelength of 385 nm, so it is better to provide LEDs that emit wavelengths of 365, 375, 385, 395, and 405 nm evenly so as to attract as many kinds of insects as possible.

[0042] In the LED array 5, for example, the LED 5a1 at the top of the central row in Figures 2(A) and 3 should be an LED that emits visible light wavelengths. The reason for this is that if all of the LEDs 5a constituting the LED array 5 are limited to those that emit invisible light wavelengths, whether the LED 5a is emitting invisible light wavelengths cannot be detected by the human eye in the event of a break in the wiring board or other electrical wiring. By providing one LED 5a1 that emits visible light wavelengths, it is possible to confirm that the LED 5a is emitting invisible light wavelengths. Note that the LED 5a1 that emits visible light wavelengths may be provided not on the wiring board but, for example, on the upper outer surface of the rear case half 3a.

[0043] [Insect trapping sheet 6] As shown in Figure 4(B), the insect trapping sheet 6 is made of a transparent resin sheet 6a and an adhesive 6b for capturing insects, which is coated on one side of the transparent resin sheet 6a. The insect trapping sheet 6 has engaging holes (round holes) 6d at its four corners, and a release film covers the adhesive 6b before installation, and the release film is preferably peeled off after installation.

[0044] As shown in Figure 4 (A), the insect trapping sheet 6 is attached so that the adhesive 6b faces toward the front case half 3b, and the engaging holes (round holes) 6d at the four corners are fitted onto the locking pins 3a7 that protrude forward from the top and bottom four corners of the first square frame member 3a4 provided on the rear case half 3a, thereby closing the opening of the first square frame member 3a4 and sealing the internal space of the rear case half 3a.

[0045] When the front case half 3b is closed against the rear case half 3a, the insect trapping sheet 6 is sandwiched at its periphery between the first square frame member 3a4 on the rear case half 3a and the second square frame member 3b2 on the front case half 3b. This prevents the insect trapping sheet 6 from detaching and falling off even when many insects are trapped by the insects and the insects struggle or are subjected to gravity. For ease of handling, the adhesive 6b formed on the insect trapping sheet 6 is preferably coated so as to avoid the periphery that overlaps with the second square frame member 3b2, as shown in Figure 4(B). However, the adhesive 6b may be coated over the entire surface.

[0046] In addition, the first square frame member 3a4 and the second square frame member 3b2 may be arranged so as to be freely fitted into and detached from the rear case half 3a and the front case half 3b, and when removed, they may be assembled with the insect trapping sheet 6 sandwiched between them and then fitted into the rear case half 3a.

[0047] The adhesive 6b to be used is one that has adhesiveness to Lepidoptera, Coleoptera, Hemiptera, Thripida, Hymenoptera, Diptera, etc. A resin-based adhesive is used as the adhesive 6b, but an adhesive containing a plant-derived component may also be used.

[0048] The adhesive 6b may be made by taking advantage of the tendency of insects to be attracted to specific colors. Specifically, insects that are easily attracted and trapped by fluorescent yellow include midges, leafhoppers, mirid bugs, and thrips. Furthermore, insects that are somewhat easily trapped include trichomes, thrips, and flower bugs. Therefore, the adhesive 6b can be colored fluorescent yellow to the extent that it does not block the light from the LED. Alternatively, an adhesive colored green, which attracts insects, can be used. Furthermore, as the adhesive sheet adhesive 6b, a coating agent containing pheromones may be applied to one side of the transparent sheet 6a, utilizing insect pheromones as an attraction. The adhesive 6b must not block the light from the LED.

[0049] Furthermore, as shown in Figure 4(B), it is preferable to apply an insect-attracting odor component 6c to the widthwise center of the adhesive 6b. Alternatively, the adhesive 6b may contain an insect-attracting odor component, and the entire surface may emit an insect-attracting odor. The scents that attract insects vary depending on the type of insect, and anything that contains an odor component that insects like may attract insects. Examples of odor components that attract insects include the odor components of decaying fruits and vegetables. Carboxylic acids such as butyric acid attract mosquitoes.

[0050] 2(B), the power supply unit 7 includes a plug 7a electrically connected to a 100- or 200-volt general power outlet, a power cord 7b, and a step-down circuit 7c attached to, for example, the wiring board 5b for stepping down the voltage of the current taken in through the plug 7a to a required low voltage, for example, 1.8 volts, to supply power to the LED array 5. The plug 7a may be recessed in the lower rear surface of the rear case half 3a and connected to the outlet by an extension cord. Alternatively, a USB may be provided instead of the plug 7a.

[0051] [Operation of Insect Trap 1] The operation of insect trap 1 will be described with reference to Figures 1 to 4. According to the above-described insect trap 1, when the latching pins 3a7 at the top and bottom corners of the first square frame member 3a4 of the rear case half 3a are fitted into the latching holes 6d at the four corners of the insect trapping sheet 6 and the front case half 3b is closed to the rear case half 3a, the peripheral edge of the insect trapping sheet 6 is sandwiched between the first square frame member 3a4 and the second square frame member 3b2, and the interior of the first square frame member 3a4 is closed by the insect trapping sheet 6.

[0052] In this configuration in which the peripheral portion of the insect trapping sheet 6 is sandwiched between the first square frame member 3a4 and the second square frame member 3b2, the adhesive 6b applied to the insect trapping sheet 6 does not need to be applied to the peripheral portion of the transparent sheet 6a, as the peripheral portion of the insect trapping sheet 6 is firmly supported and no gaps are created, eliminating the risk of insects entering.By using an insect trapping sheet 6 that is not applied to the peripheral portion of the transparent sheet 6a, the surfaces where the insect trapping sheet is sandwiched between the first square frame member 3a4 and the second square frame member 3b2 do not become sticky, and the insect trapping sheet 6 can be easily replaced.

[0053] When the LED array 5 is supplied with power through a power supply means 7, ultraviolet light emitted by the LED array 5 passes through a transparent insect-trapping sheet 6 and further passes through the insect entry holes 4, and the odor that attracts insects and is emitted from the odor component 6c of the insect-trapping sheet 6 fills the inside of the front case half body 3b and diffuses to the outside through the insect entry holes 4.

[0054] Therefore, insects are attracted by the ultraviolet rays and the smell to the insect entry hole 4 and enter the front case half 3b. The insects that have entered the front case half 3b move further toward the LED array 5, which is the source of the ultraviolet rays emitted by the LED array 5, but they collide with the insect trapping sheet 6 and are captured.

[0055] Since the insect trapping sheet 6 completely closes the inside of the rear case half 3a, insects cannot enter the inside of the rear case half 3a. When many insects are trapped on the insect trapping sheet 6, the front case half 3b can be opened to replace the insect trapping sheet 6.

[0056] [Second embodiment] Figure 5 shows an insect trap 1B according to a third embodiment of the present invention. This insect trap 1B is identical to the insect trap 1 according to the first embodiment, except for the configuration described below. The same components of the insect trap 1A as those of the insect trap 1 according to the first embodiment are designated by the same reference numerals and will not be described again.

[0057] The insect trap 1 of the first embodiment has locking pins 3a7 protruding forward from the upper and lower four corners of the first square frame member 3a4 of the rear case half 3a, and locking holes 3b3 at the upper and lower four corners of the second square frame member 3b2 of the front case half 3b. The first square frame member 3a4 and the second square frame member 3b2 clamp the peripheral portion of the insect trapping sheet 6, and the four locking pins 3a7 are locked into the locking holes 6d at the four corners of the insect trapping sheet 6 in a penetrating state.

[0058] In contrast, in the insect trap 1A of this embodiment, the arrangement of the locking pins and locking holes is reversed: the second square frame member 3b2 of the front case half 3b has locking pins 3b5 protruding rearward from the top and bottom four corners, and the first square frame member 3a4 of the rear case half 3a has locking holes 3a8 at the top and bottom four corners.

[0059] In this insect trap 1A, the front case half 3b is opened, and then the adhesive is oriented toward the front case half 3b, and the engaging holes 6d at the four corners of the insect trapping sheet 6 are fitted over the locking pins 3b5 that protrude rearward from the top and bottom four corners of the second square frame member 3b2 of the front case half 3b. When the front case half 3b is closed against the rear case half 3a, the first square frame member 3a4 and the second square frame member 3b2 hold the periphery of the insect trapping sheet 6. Because the insect trapping sheet 6 completely encloses the interior of the rear case half 3a, insects cannot enter the interior of the rear case half 3a.

[0060] In the insect trap 1A of this embodiment, a pocket is formed by closing the bottom surface 3b6 between the front semi-cylindrical portion 3b1 of the front case half 3b and the lower end of the second rectangular frame member 3b2, and this pocket is adapted to house an odorous substance storage box (odorous substance storage portion) 8. The odorous substance storage box 8 contains an odor-generating substance that emits an odor that attracts insects, such as a decay-smelling substance from fruit or vegetables. The decay odor released from the decay-smelling substance fills the inside of the front case half 3b and flows out through the insect entry hole 4, thereby attracting insects.

[0061] [Third embodiment] Figure 6 shows an insect trap 1B according to a third embodiment of the present invention. This insect trap 1B is identical to the insect trap 1 according to the first embodiment, except for the configuration described below. The same components of the insect trap 1B as those of the insect trap 1 according to the first embodiment are designated by the same reference numerals, and their description will be omitted.

[0062] In the insect trap 1 of the first embodiment, the power supply means 7 comprises a plug 7a, a power cord 7b, and a step-down circuit 7c, so that a long extension cord is required for use in a place far from a power source, and it is unsuitable for use in greenhouse cultivation far from a power source or in rainy weather.

[0063] In contrast, in this insect trap 1B, the case 3 is erected on a battery storage box 2a formed in a box-like shape on the installation stand 2. The power supply means 7 includes a plug 7a, a power cord 7b, a step-down circuit 7c, and a storage battery 7d.

[0064] The battery housing box 2a may be molded integrally with the box-shaped installation base 2. The storage battery 7d may be provided so as to be housed inside the rear half of the case.

[0065] The storage battery 7d receives power from a general power source via the plug 7a and the power cord 7b, stores the power, and supplies a required small voltage, for example, 1.8 volts, to the LED array.

[0066] Power is supplied from the storage battery 7d to the LED array 5 by turning on a switch provided on an appropriate outer surface of the rear case half 3a, or by turning on an automatic switch consisting of a light sensor that detects the amount of light as it gets darker in the evening and turns on power.

[0067] As a power source for storing electricity in the storage battery 7d, in addition to connecting the plug 7a to a general power source, a solar power generation panel (power generation means; not shown) may be provided separately from the insect trap 1B. The solar power generation panel may be configured to be embraced on the outer surface of the rear case half 3a.

[0068] The storage battery 7d stores the required low voltage power in the storage battery 7d through the plug 7a and the step-down circuit 7c during the daytime, supplies power to the LED array 5 from the evening until dawn, and the LED array 5 radiates ultraviolet light, so that the insect trap catches insects at night.

[0069] The storage battery 7d is preferably one of a lithium titanate battery (SCiB), an all-solid-state battery, and a magnesium-sulfur secondary battery, which can store a large amount of power with a short charging time.

[0070] SCiBs are secondary batteries that use organic sulfur as the positive electrode material and lithium titanate nanocrystals, a ceramic material, on the surface of the negative electrode material, with lithium ions in the electrolyte responsible for electrical conduction. All-solid-state batteries use oxides or sulfides as the positive electrode material and metallic lithium or carbon as the negative electrode material, with an inorganic solid electrolyte separating the positive and negative electrodes. Magnesium-sulfur secondary batteries use organic sulfur as the positive electrode and magnesium as the negative electrode, with magnesium ions in the electrolyte responsible for electrical conduction.

[0071] According to the insect trap described above, a two-part case that defines a vertically long dome space is set upright on an installation base, the front case half having an insect entry hole is removable or can be opened to one side relative to the rear case half, an LED array that emits ultraviolet rays that attract insects is provided on the inside of the rear case half, an insect trapping sheet having a transparent sheet coated on one side with an adhesive that captures insects is removably stretched so as to divide the vertically long dome space into the front and rear sides with the adhesive facing forward, and power is supplied to the LED array by a power supply means, so that the insect trapping sheet can be attached firmly while maintaining a flat state and is easy to attach and detach, and an insect trap can be provided that does not allow insects to come into contact with the LED array.
