[0010] The present invention provides a pest control device that exterminates pests by arranging a light source that irradiates ultraviolet light inside the housing of the pest control device and irradiating ultraviolet light on pests such as cockroaches that enter the inside of the housing.
[0011] It has been known for some time that ultraviolet light is effective in exterminating pests such as cockroaches, including the German cockroach. The pest control device of the present invention is small and can be easily placed inside food warehouses and the like where pests such as cockroaches tend to gather, and by leaving the pest control device installed for a long period of time, the pests in the food warehouses and the like can be weakened by irradiating them with ultraviolet light, thereby enabling the pests to be efficiently exterminated.
[0012] Next, a pest control device according to an embodiment of the present invention will be described with reference to the drawings. Here, the pest control device will be described with cockroaches as the target pests, but the pests are not limited to cockroaches, and the device can be applied to any pest of the same size as a cockroach. In addition, the embodiment described below shows one specific example of the present invention, and therefore the arrangement, functions, values, etc. of the components described in the embodiment are merely examples, and the scope of the present invention should not be limited by these. EXAMPLES
[0013] FIG. 1A is a perspective view showing the entire pest-control device 1 in the first embodiment.
[0014] The figure shows a perspective view of the entire pest control device 1 as seen from diagonally above. The pest control device 1 is basically composed of a rectangular parallelepiped housing 3 and a bottom plate 40 arranged to close the bottom of the housing 3.
[0015] 1A, the housing 3 is composed of a rectangular top plate 10 located at the top, a pair of rectangular side plates 20 attached perpendicular to the longitudinal direction, and a pair of rectangular end plates 30 attached perpendicular to the ends in the lateral direction. A bottom plate 40 is attached so as to cover the bottom of the housing 3. In the present invention, the same direction as the longitudinal direction of the top plate 10 is referred to as the "longitudinal direction", and the same direction as the lateral direction is referred to as the "lateral direction".
[0016] Along the bottom edge of each side plate 20 and end plate 30, a rectangular cutout 25 and a rectangular cutout 35 are provided.
[0017] The cutouts 25, 35 are openings for cockroaches to enter and exit. The size of the cutouts 25, 35 is desirably set to a height and width that allows easy entry and exit of cockroaches. The size of the cutouts 25, 35 varies depending on the type and size of the cockroach, but specifically, the cutouts 25, 35 are 3 mm to 30 mm in height, preferably 6 mm to 15 mm, and more preferably 8 mm to 12 mm. The width of the cutouts 25, 35 is set so that at both ends of the bottom edge of the side plate 20 and the end plate 30, at least 5 mm to 10 mm is left in contact with the bottom plate 40. Note that multiple narrow cutouts 25, 35 may be provided within that size.
[0018] The bottom plate 40 is provided so as to cover the opening at the bottom of the housing 3, and has a rectangular shape that is slightly larger than the housing 3. The edge of the bottom surface of the bottom plate 40 is formed in a slope around the entire periphery so that cockroaches of all sizes can easily climb it. In addition, it is preferable that the edge of the bottom plate 40 is sloped so that even larvae with a body length of about 1 mm can easily climb it. In the first embodiment, the housing 3 is in a rectangular parallelepiped shape, but it is not limited thereto, and may be in any suitable shape such as a cube, a triangular prism, a truncated pyramid, a triangular pyramid, a cylinder, a cone, a hemisphere, or the like.
[0019] The size of the housing 3 is a length of about 50 mm to 450 mm, preferably 80 mm to 300 mm, and more preferably 130 mm to 170 mm, a width of about 20 mm to 150 mm, preferably 25 mm to 100 mm, and more preferably 30 mm to 60 mm, and a height of about 20 mm to 100 mm, preferably 25 mm to 60 mm, and more preferably 30 mm to 50 mm, but is not limited thereto.
[0020] 1B, a plurality of partition members D and E are provided on the upper surface of the bottom plate 40, and gaps are formed between the partition members D and E. Cockroaches prefer small spaces, so gaps through which cockroaches can pass are formed between the partition members D and E, and the cockroaches are irradiated with ultraviolet rays. Cockroaches that enter the inside of the housing 3 through the notches 25 and 35 pass through the gaps between the partition members D and E, or remain in the gaps for a long time, and are exposed to a lot of ultraviolet rays.
[0021] Partition members D and E are made of an appropriate material, for example, wood, synthetic resin, aluminum alloy metal, etc. Since cockroaches prefer dark places, the surfaces of partition members D and E may be coated with a black paint or the like.
[0022] The size of the partition members D and E is preferably 2 mm to 15 mm in height and 5 mm to 20 mm in width, preferably 4 mm to 12 mm in height and 7 mm to 15 mm in width, and more preferably 5 mm to 10 mm in height and 8 mm to 12 mm in width, but is not limited thereto. The length of the partition members D and E is appropriately adjusted so as to fit inside the housing 3.
[0023] In Example 1, an example of the pest control device 1 installed in an unmanned storage warehouse or the like is shown, but by adjusting the type of ultraviolet light emitted from the light source unit 60 and narrowing the irradiation range of the light (ultraviolet light) emitted from the light source unit 60 by the opening 55 provided near the center of the middle plate 50, the device can also be installed in a kitchen or the like where people come and go. In this case, since ultraviolet light is basically harmful to the human body, when the pest control device 1 of Example 1 is placed directly on a horizontal surface of kitchen equipment or the like or on a floor, the pest control device 1 can be used safely by adjusting the irradiation range of the ultraviolet light so that the irradiation light emitted from the light source unit 60 does not leak from the housing 3 to the outside.
[0024] In the pest control device 1, an example has been shown in which the aperture 55 near the center of the middle plate 50, through which the irradiation light emitted from the light source unit 60 passes, is rectangular, but it is not limited to a rectangular shape and other shapes such as a circle, a diamond, a polygon, etc. can be used, and the aperture 55 may be provided in multiple places on the middle plate 50 instead of in one place. The aperture 55 does not have to be near the center of the middle plate 50, and may be on the periphery of the middle plate 50. An optical lens member such as a Fresnel lens, a concave-convex lens, or a combination thereof that can transmit ultraviolet light and expand or reduce the irradiation range may be disposed in the aperture 55.
[0025] The top plate 10, side plates 20, end plates 30, and bottom plate 40 that constitute the housing 3 are preferably made of aluminum or an aluminum alloy, but other metals such as iron, stainless steel, magnesium alloys, etc. Also, other materials such as synthetic resins, wood-based materials, and ceramics may be used, as long as they are resistant to ultraviolet light, and are not limited to metal materials.
[0026] The housing 3 may be manufactured by aluminum die casting or bending an aluminum plate without using the top plate 10, side plates 20, and end plates 30. It may also be a molded product made of synthetic resin. Furthermore, by using a thermally conductive material for the housing 3, the heat generated by the light source unit 60 can be efficiently dissipated to the outside through the housing 3.
[0027] 1B is a longitudinal side view of the pest-control device 1 in Example 1. A plurality of partition members D and partition members E arranged on the bottom plate 40 are arranged inside the cutout portion 25 of the side plate 20 of the housing 3. Both the partition members D and partition members E have a rectangular parallelepiped shape.
[0028] 1C is a side view of the pest control device 1 in the short side direction in Example 1. The end plate 30 is a rectangular flat plate, and a rectangular cutout 35 is provided on the bottom side where it contacts the bottom plate 40. Inside the cutout 35, partition members D and E arranged in the longitudinal direction on the bottom plate 40 are arranged at a certain interval. Cockroaches that enter through the cutout 35 of the housing 3 pass through (wander around) or stay in the gaps formed between the partition members D and E, etc., as a passageway.
[0029] FIG. 2A is an oblique view showing the pest control device 1 in Example 1 with the side plate 20 arranged in the longitudinal direction removed, FIG. 2B is a side view of the same, and FIG. 2C is a side view showing the same with the end plate 30 arranged in the lateral direction removed.
[0030] The housing 3 is composed of a top plate 10, side plates 20, end plates 30, bottom plate 40, and middle plate 50, all of which are rectangular. The top plate 10, middle plate 50, and bottom plate 40 are placed on the housing 3 from the top so that they are parallel and horizontal. Both ends of the top plate 10, middle plate 50, and bottom plate 40 are fixed to a pair of end plates 30 that stand vertically from the bottom plate 40. As shown in the figure, in the first embodiment, the bottom plate 40 is one size larger than the top plate 10, but it may be the same size as the top plate 10.
[0031] The housing 3 is assembled by typical fastening means (not shown) in which the top plate 10, side plates 20, end plates 30, bottom plate 40, and middle plate 50 are connected by fasteners such as psicoronats (cube nuts) and bolts. Note that fixing metal fittings such as L-shaped metal fittings may be used instead of fastening means such as psicoronats and bolts.
[0032] The partition member AE forms gaps through which cockroaches that have entered the housing 3 can pass or remain. As shown in Figures 2A and 2B, the partition members A and B are disposed on the lower surface (rear surface) of the top plate 10, and face the partition member C disposed on the upper surface of the middle plate 50, forming gaps between the partition members A, B, and C. Furthermore, by disposing the partition members D and E on the upper part of the bottom plate 40, gaps through which cockroaches can pass or remain are formed.
[0033] FIG. 3A is a perspective view of the top plate of the pest control device 1 in the first embodiment, FIG. 3B is a plan view of the same, and FIG. 3C is a side view of the same. A rectangular parallelepiped light source unit 60 is provided on the underside of the top plate 10 along the longitudinal direction of the top plate 10. The light source unit 60 is composed of a substrate 70 and a plurality of light-emitting elements 72 such as LEDs mounted on the surface of the substrate 70. The light-emitting elements 72 are ultraviolet light-emitting elements, and irradiate ultraviolet light in the direction of the bottom plate 40. In the first embodiment, three light-emitting elements 72 are arranged in a row in the longitudinal direction, but the number of light-emitting elements 72 is not limited to three, and may be mounted on the surface of the housing 3 depending on the size of the housing 3 and the required amount of irradiation light. The light-emitting elements 72 may be arranged in parallel in multiple rows instead of in a single row, or may be arranged in a matrix shape. A plurality of electronic components (not shown) for controlling the amount of irradiation light of the light-emitting elements 72 are mounted on the substrate 70.
[0034] A long partition member A is disposed in the longitudinal direction on the underside of the tabletop 10 along the outer side of the light source unit 60. A pair of partition members B are disposed between the longitudinal ends of the tabletop 10 and the partition member A so as to be symmetrical in the lateral direction with the partition member A in between. Furthermore, two rows of gaps through which cockroaches can pass are provided between the partition member A and the light source unit 60, and between the light source unit 60 and the partition member B.
[0035] The slit 15 provided in the top plate 10 is a cutout for inserting a tool such as a screwdriver to facilitate removal of the top plate 10 from the housing 3.
[0036] Fig. 4A is a perspective view of the pest control device 1 in Example 1 near the middle plate 50, Fig. 4B is a plan view of the same, and Fig. 4C is a side view of the same. The rectangular middle plate 50 is horizontally disposed between the top plate 10 and the bottom plate 40. Both longitudinal ends of the middle plate 50 are connected to a pair of end plates 30 that stand vertically. A rectangular opening 55 is cut out in the longitudinal direction near the center of the middle plate 50. Four partition members C are disposed at regular intervals around the opening 55 so that they are parallel to each other and have their short sides facing in the short direction. A gap is provided between the pair of partition members C so that cockroaches can pass through and stay there.
[0037] As shown in Figs. 4A and 4B, a rectangular opening 55 is formed near the center of the middle plate 50. The opening 55 serves as a diaphragm that efficiently irradiates the ultraviolet light emitted from the light emitting element 72 to the partition members D and E of the bottom plate 40, so the opening 55 is preferably located near the area directly below the light emitting element 72. In addition, in the first embodiment, the opening 55 has a rectangular shape similar to the shape of the housing 3 and the light source unit 60. However, for example, when the light source unit 60 is circular, the opening 55 may also have a circular shape similar to that of the light source unit 60. In addition, the entire inner surface of the housing 3 may be coated with a black paint or the like to absorb light that has entered the internal space of the housing 3 and prevent diffuse reflection. Instead of the opening 55 of the middle plate 50, an optical lens member or the like may be used as the diaphragm member.
[0038] For example, the top plate 10, side plates 20, end plates 30 and middle plate 50 constituting the housing 3 may be made of aluminum material that is highly UV reflective, or the inner surface of the housing 3 may be coated with aluminum foil that is highly UV reflective or with a coating such as white UV resist ink that is highly UV reflective, so that UV rays are reflected inside the housing 3 and the UV rays emitted from the light source unit 60 are efficiently irradiated toward the bottom plate 40.
[0039] Fig. 5A is a perspective view of the vicinity of the bottom plate 40 of the pest-control device 1 in Example 1, Fig. 5B is a plan view of the same, and Fig. 5C is a side view of the same. Three partition members E are arranged parallel to each other in the short direction near the center of the upper surface of the bottom plate 40. Two partition members D are arranged on each side of the partition members E and parallel to each other in the long direction. EXAMPLES
[0040] FIG. 6A is a perspective view showing the entire pest-control device 100 in the second embodiment, FIG. 6B is a side view of the pest-control device 100 in the longitudinal direction, and FIG. 6C is a side view of the pest-control device 100 in the lateral direction.
[0041] The pest control device 100 is composed of a housing 103 and a bottom plate 140. The housing 103 is composed of a rectangular parallelepiped top plate 110 and rectangular parallelepiped end plates 130 hanging down from both ends in the longitudinal direction of the top plate 110, and has a Π-shaped cross section in the short direction. The bottom plate 140 has a rectangular parallelepiped shape that is approximately the same as the top plate 110, and is composed of a pair of side plates 120 that are erected vertically from both ends in the longitudinal direction and have an inverted Π-shaped cross section in the short direction. The pair of side plates 120 constitute the pest control device 100 in such a way that the upper ends in the longitudinal direction contact the top plate 110 and the short sides in the short direction contact the side ends of the end plates 130. The bottom plate 140 and the side plates 120 are of an integral structure, but may be assembled separately using fasteners such as bolts.
[0042] 6A, housing 103 is composed of rectangular top plate 110 located at the top, a pair of rectangular side plates 120 attached perpendicular to the longitudinal direction, and a pair of rectangular end plates 130 attached perpendicular to the ends in the transverse direction. A bottom plate 140 is attached so as to cover the bottom of housing 103. In the present invention, the same direction as the longitudinal direction of top plate 110 is referred to as the "longitudinal direction", and the same direction as the transverse direction is referred to as the "transverse direction".
[0043] 6A, rectangular cutouts 125 and 135 are provided along the bottom sides of side plate 120 and end plate 130, respectively. End plate 130 is connected to side plate 120 by bolts 137.
[0044] The cutouts 125, 135 are openings for cockroaches to enter and exit. The size of the cutouts 125, 135 is desired to have a height and width that allow cockroaches to easily enter and exit. The size of the cutouts 125, 135 varies depending on the type and size of the cockroach. Specifically, as in the first embodiment, the cutouts 125, 135 have a height of about 3 mm to 30 mm, preferably 6 mm to 15 mm, and more preferably 8 mm to 12 mm. The width of the cutouts 125, 135 is set so that at both ends of the bottom of the side plate 120 and the end plate 130, at least about 5 mm to 10 mm is left in contact with the bottom plate 140. Note that multiple cutouts 125, 135 with smaller widths may be provided within that size.
[0045] The bottom plate 140 is provided so as to cover the opening at the bottom of the housing 103, and has a rectangular shape similar to that of the housing 103. The edge of the bottom surface of the bottom plate 140 may be formed in a slope around the entire periphery so that cockroaches of all sizes can easily climb it. In addition, although the housing 103 in the second embodiment has a rectangular parallelepiped shape, it is not limited thereto, and may have any other suitable shape such as a cube, a triangular prism, a truncated pyramid, a triangular pyramid, a cylinder, a cone, a hemisphere, or the like, as in the first embodiment. In addition, the housing 103 is preferably the same size as the housing 3 in the first embodiment.
[0046] As shown in Fig. 6B, a plurality of partition members 100D, 100E are installed on the upper surface of the bottom plate 140, and gaps are formed between the partition members 100D and 100E. Since cockroaches prefer narrow spaces, gaps through which the cockroaches can pass are formed between the partition members 100D and 100E, and the cockroaches are irradiated with ultraviolet rays. Cockroaches that enter the inside of the housing 103 through the notches 125, 135 pass through the gaps between the partition members 100D and 100E or stay in the gaps for a long time, and are exposed to a lot of ultraviolet rays.
[0047] As in the first embodiment, the partition members 100D and 100E are made of an appropriate material, such as wood, synthetic resin, aluminum alloy metal, etc. Since cockroaches prefer dark places, the surfaces of the partition members 100D and 100E may be coated with a black paint or the like.
[0048] The size of the partition members 100D and 100E is, as in the first embodiment, preferably 2 mm to 15 mm in height and 5 mm to 20 mm in width, preferably 4 mm to 12 mm in height and 7 mm to 15 mm in width, more preferably 5 mm to 10 mm in height and 8 mm to 12 mm in width, but is not limited thereto. The distance between the partition members 100D and 100E should be set to a level that allows a cockroach to pass through. The length of the partition members 100D and 100E is adjusted appropriately so that they can fit inside the housing 103.
[0049] In the second embodiment, as in the first embodiment, an example of a pest control device 100 that is installed in an unmanned storage warehouse or the like is shown, but by adjusting the type of ultraviolet light emitted from the light source unit 160 and the irradiation range of the irradiated light (ultraviolet light), the device can also be installed in a kitchen or the like where people come and go.
[0050] As in the first embodiment, the top plate 110, side plates 120, end plates 130, and bottom plate 140 constituting the housing 103 are preferably made of aluminum or an aluminum alloy, but other metals such as iron, stainless steel, magnesium alloys, etc. Also, other materials such as synthetic resins, wood-based materials, and ceramics may be used, not limited to metal materials, as long as they are resistant to ultraviolet rays.
[0051] Also, the housing 103 may be manufactured by aluminum die casting or bending an aluminum plate without using the top plate 110, the side plates 120, and the end plates 130. It may also be a molded product made of synthetic resin. Furthermore, by using a thermally conductive material for the housing 103, the heat generated by the light source unit 160 can be efficiently dissipated to the outside via the protrusions 112 on the upper part of the housing 103.
[0052] 6B, a plurality of partition members 100D, 100E disposed on bottom plate 140 are disposed inside cutout portion 125 of side plate 120 of housing 103. Both partition members 100D, 100E have a rectangular parallelepiped shape.
[0053] 6C is a side view of the pest-control device 100 in the short side direction in Example 2. The end plate 130 is a rectangular flat plate, and a rectangular cutout 135 is provided on the bottom side where the end plate 130 contacts the bottom plate 140. Inside the cutout 135, the partition members 100D and 100E arranged in the longitudinal direction on the bottom plate 140 are arranged at a certain interval. Cockroaches that enter through the cutout 135 of the housing 103 use the gaps formed between the partition members 100D and 100E, etc., as a passageway to pass through (wander around) or stay there.
[0054] 6A and other figures, the top plate 110 has a plurality of ridges 112 formed in the longitudinal direction. The ridges 112 function as a heat sink that dissipates heat generated inside the housing 103 to the outside.
[0055] 6D is a plan view of the vicinity of the top plate 110 of the pest control device 100 in Example 2. The multiple protrusions 112 formed on the top plate 110 are formed over about 2 / 3 of the length of the top plate 110, but may be formed over the entire upper surface of the top plate 110. The double circle indicates a bolt 136 for integrally connecting the top plate 110 to the side plate 120 and the end plate 130.
[0056] FIG. 7A is a perspective view showing the pest-control device 100 in the second embodiment, taken along line BB in FIG. 6D.
[0057] The housing 103 is composed of a top plate 110, side plates 120, end plates 130, and a bottom plate 140, all of which are rectangular. The housing 103 is placed so that the top plate 110 and the bottom plate 140 are parallel and horizontal. Both ends of the top plate 110 and the bottom plate 140 are fixed to a pair of end plates 130 that stand vertically from the bottom plate 140. As shown in the figure, in the second embodiment, the bottom plate 140 has approximately the same size as the top plate 110, but this is not limited to this.
[0058] In the second embodiment, similarly to the first embodiment, the housing 103 and the side plate 120 are assembled by a general fastening means of connecting them using a psi-coronat (not shown) and bolts 136 and 137. Note that instead of the fastening means using the psi-coronat and the bolts 136 and 137, a fixing metal fitting such as an L-shaped metal fitting may be used.
[0059] The partition members 100D and 100E, when combined, form a gap through which a cockroach that has entered the inside of the housing 103 can pass or remain there.
[0060] Fig. 7B is a cross-sectional view taken along line BB in Fig. 6D, and Fig. 7C is a cross-sectional view taken along line AA in Fig. 6B. As shown in Fig. 7B, two partition members 100E are arranged perpendicular to two partition members 100D arranged on bottom plate 140. Fig. 7C also shows that three partition members 100D are arranged in the longitudinal direction, and partition member 100E is arranged at the rear side of those partition members 100D so as to block partition member 100D.
[0061] 8A is an oblique view of the top plate 110 seen diagonally from below, FIG. 8B is a longitudinal side view of the top plate 110 seen horizontally, FIG. 8C is a transverse side view of the top plate 110 seen horizontally, and FIG. 8D is a rear view of the top plate 110 seen from below.
[0062] As shown in FIG. 8A and other figures, the light source unit 160 having a substantially rectangular parallelepiped shape is provided on the lower surface of the top plate 110 along the longitudinal direction of the top plate 110. The light source unit 160 is composed of a substrate 170 and a plurality of light emitting elements 172 such as LEDs mounted on the surface of the substrate 170. The light emitting elements 172 are ultraviolet light emitting elements, and irradiate ultraviolet light in the direction of the bottom plate 140. In the second embodiment, three light emitting elements 172 are arranged in a row in the longitudinal direction, but the number of light emitting elements 172 is not limited to three, and may be mounted on the surface of the housing 103 depending on the size of the housing 103 and the required amount of irradiation light. The light emitting elements 172 may be arranged in a plurality of parallel rows instead of in a row, or may be arranged in a matrix shape. A plurality of electronic components (not shown) for controlling the amount of irradiation light of the light emitting elements 172 are mounted on the substrate 170. A hole 138 for inserting a power cable is provided in a corner of the top plate 110.
[0063] 9A is a perspective view of the state where the top plate 110 is removed, as seen from above, and FIG. 9B is a plan view of the state where the top plate 110 is removed. As shown in FIG. 9A, a set of three partition members 100D are arranged on the bottom plate 140 so as to be parallel to the longitudinal direction of the bottom plate 140. Between the set of three partition members 100D, two partition members 100E are arranged in the short direction so as to be perpendicular to the set of three partition members 100D. In addition, a square-shaped frame member 100F is arranged around the partition members 100D and 100E so as to contact the side plate 120 and the end plate 130. Right-angled triangular support members 101F are provided at multiple points on the upper surface of the frame member 100F so as to contact the side plate 120 and the end plate 130. The support member 101F supports the side plates 120 and the end plates 130 so as to keep them perpendicular to the bottom plate 140, and also serves to reinforce them so as not to bend or collapse.
[0064] Cockroaches tend to prefer narrow gaps and dim, narrow places, so gaps are provided between the partition members AE or the partition members 100D and 100E provided in the housings 3 and 103 to darken the inside of the housings 3 and 103, providing an environment in which they can easily stay in the housings 3 and 103. The surfaces of the middle plate 50 arranged inside the housing 3, the space surrounded by the side plates 20, the end plates 30 and the bottom plate 40 constituting the housing 3, and the space surrounded by the side plates 120, the end plates 130 and the bottom plate 140 constituting the housing 103 are painted black, for example, to keep the inside of the housings 3 and 103 dark and prevent external light from being reflected. When a cockroach enters the inside of the housing 3 and 103 and passes through the gaps between the partition members AE or the partition members 100D and 100E or stays there, it is exposed to ultraviolet light for a long period of time, and ultraviolet light accumulates in the cockroach's body. As exposure to UV rays accumulates, cockroaches become weaker and eventually die. Even if they do not die, their reproductive ability decreases, which helps prevent reproduction. Intermittent UV exposure is particularly effective for German cockroaches, and because UV rays have no recovery effect and have a cumulative effect, they usually die within a few days to a few dozen days after exposure, so the same effect can be expected as with continuous UV exposure.
[0065] The pest control device 1,100 of the present invention is used continuously, day after day, and therefore needs to have a long life and be energy-saving. However, since the ultraviolet light-emitting elements used are energy-saving and long-life ultraviolet light-emitting elements 72, 172, etc., the device can be used stably for a long period of time.
[0066] The light source unit 60, 160 is provided with a control unit (not shown) that supplies power to cause the light emitting element 72, 172 such as an LED to emit light. For example, the control unit receives power from a commercial power outlet installed in a food storehouse or the like, performs A / D conversion, and supplies DC power to the light emitting element 72, 172. The control unit controls the light source unit 60, 160 to have a normal pattern (continuous emission pattern) in which ultraviolet light is continuously emitted, and an intermittent pattern (intermittent emission pattern) in which the light emitting element 72, 172 intermittently blinks at a fixed cycle or an irregular cycle that changes randomly to intermittently repeat the emission of ultraviolet light.
[0067] The housing 3, 103 may be provided with a switch (not shown) for turning on / off the power supply to the control unit, a changeover switch (not shown) for switching between continuous and intermittent emission of ultraviolet light from the light source unit 60, 160 having the light emitting element 72, 172, and an indicator for indicating the continuous emission state and the intermittent emission state of the light source unit 60, 160 so as to turn on when the light source unit 60, 160 is turned on and turn off when the light source unit 60, 160 is turned off. Furthermore, the indicator may be provided with a function for indicating the irradiation amount of ultraviolet light emitted from the light source unit 60, 160. Also, an overheat prevention device for turning off the power when the light source unit 60, 160 overheats may be built in. The indicator can indicate the emission state of ultraviolet light from the light source unit 60, 160 having the light emitting element 72, 172 using appropriate LEDs such as white LEDs, blue LEDs, red LEDs, etc.
[0068] In addition, to prevent the housing 3,103 from shifting position or falling over due to slight vibration or contact, etc., a non-slip material such as rubber may be placed on the edge of the bottom of the housing 3,103, or on the bottom of the bottom plate 40,140 in the case of a housing 3,103 having a bottom plate 40,140, a rubber magnet may be placed on an installation surface that has the property of attracting magnets, such as an iron plate, and an adhesive material such as adhesive tape may be placed on other general installation surfaces.
[0069] Furthermore, a small battery such as a dry cell or a lithium-ion rechargeable battery may be mounted as the power source for supplying power to the light source units 60 and 160, thereby providing a pest control device 1,100 that is small in size, highly portable, and convenient to use.
[0070] The ultraviolet rays emitted from the light emitting elements 72, 172 of the light source units 60, 160 are electromagnetic waves in the vicinity of 10 to 405 nm, and for cockroaches, it is particularly preferable to use the UV-C region (200 to 280 nm; deep ultraviolet). However, this does not preclude the use of the 315 to 380 nm wavelength band (UV-A) with a dominant wavelength of 365 nm, which is near ultraviolet, or the UV-B region (280 to 315 nm).
[0071] The light source unit 60, 160 includes a substrate 70, 170 on which a plurality of light emitting elements 72, 172 are surface mounted. In the present invention, the light emitting elements 72, 172 such as LEDs are used as the light source for emitting ultraviolet light, but fluorescent lamps, organic electroluminescence (EL), xenon lamps, halogen lamps, etc. that emit ultraviolet light may also be used as the light source. Also, a light source that emits visible light and has an insecticidal effect on pests such as cockroaches may also be used.
[0072] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention. [Industrial Applicability]
[0073] According to the present invention, by using a small, easy-to-use pest control device that irradiates ultraviolet rays, it is possible to effectively exterminate pests such as cockroaches that take up residence inside storage warehouses, etc., and maintain a hygienic environment.
