[first embodiment]

1 is a side view illustrating an insect trap according to an embodiment of the present invention, FIG. 2 is a sectional view illustrating an insect trap according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view illustrating an insect trap according to an embodiment of the present invention.

Referring to FIG. 1 to FIG. 3 , the components of an insect trap 1000 according to an embodiment of the present invention will be described in detail.

The insect trap 1000 of an embodiment of the present invention can include: a main body 110; an insect passage part 120, which can be detachably configured on the main body 110 to selectively allow insects Pass; the air dust collection part 130, which is configured at the bottom of the main body 110; the motor 140, which is located between the air dust collection part 130 and the insect passing part 120; the suction fan 150, which is located between the motor 140 and the insect passing part 120; Between the air dust collection parts 130, rotate by means of the motor 140; the UV LED installation part 160, which is arranged on the upper part of the insect passing part 120, is equipped with a UVLED module 161; and the capture part 170, which can It is detachably arranged at the lower part of the air dust collection part 130 to capture insects.

The insects referred to in the present invention are not limited to their species, but include various types of flying insects, and particularly mosquitoes.

Subject 110

The shape of the main body 110 is not particularly limited, but from the point of view that the suction fan 150 is installed inside, it can be cylindrical, and the material is not particularly limited, but it can be used indoors or outdoors for a long time without Manufactured with plastic-based materials that greatly increase manufacturing costs. The main body 110 has a structure open up and down so that air can pass up and down. In addition, the height of the main body 110 may be 2 cm to 20 cm, preferably 3 cm to 10 cm.

Referring to FIG. 2 and FIG. 3 , from the upper part to the lower part of the main body 110 , the insect passing part 120 , the motor 140 and the suction fan 150 may be installed on the main body 110 .

FIG. 4 is a diagram showing an insect passing portion 120 of an insect trap according to an embodiment of the present invention.

If referring to FIG. 4 , the insect passing portion 120 is a lattice form including a plurality of insect passing holes 121 through which insects can selectively pass, and the plurality of insect passing holes can be formed by means of a circular member 122 and a radial member 123. form. Specifically, the average size of the insects to be captured can be considered, and the size of the insect passing hole 121 can be adjusted. As shown in FIG. Control the size of the insect passage hole 121 accurately.

In the case of insect traps that use the suction fan used in the past to capture insects, insects such as butterflies, dragonflies, and flies that are larger than mosquitoes are also captured, and the replacement cycle of the capture part is fast, or even beneficial insects that are not pests are also captured. Problems that adversely affect ecosystems. In addition, large insects are stuck to the suction fan, which shortens the life of the motor and causes noise from the suction fan. Therefore, the inventors of the present invention economically manufactured the insect passing part 120 while controlling the size of the insect passing hole 121 so that the insect trap 1000 can selectively suck insects.

The plurality of insect passing holes 121 are distinguished by a plurality of circular members 122 and radial members 123 centered on the center of the insect passing portion 120, and are fan-shaped with a central angle of 20° to 40°. The circular member 122 may be separated from the adjacent circular member 122 by 1.0 cm to 1.5 cm, and within the range of values, the area of each insect passage hole 121 may be 100 mm ² to 225 mm ² . Therefore, insects, especially mosquitoes, are selectively passed through. On the contrary, insects with large bodies such as butterflies, dragonflies, and flies are not caught inside the insect trap 1000, and the durability of the motor can be prevented from deteriorating or reduced. The noise generated by the suction fan 150 described above.

In addition, it is preferable that the suction fan 150 is controlled so that insects do not stick to the suction fan 150 and flow into the lower part of the suction fan 150 . In conventional insect traps that use a suction fan to catch insects, insects stick to the fan blades, resulting in non-uniform rotation radius of the suction fan, deteriorating the durability of the motor and generating noise. However, when the rotational speed of the suction fan is reduced so that insects do not stick to the fan blades, there is a problem that the efficiency of catching insects adjacent to the insect trap is significantly reduced. That is, insects have a tendency to stop flying above the wind speed of 0.8m/s, but when the wind speed is too high, the insects try to escape from the airflow, so the inventors of the present invention made the insect trap 1000 so that the insects are not stuck. Simultaneously with the fan blades 151 , the mosquitoes stop flying and are captured by the suction airflow generated by the suction fan 150 .

To this end, the number of fan blades 151 may be 2 to 7, preferably 3 or 4, and the rotation speed of the suction fan 150 may be 1500 rpm to 2700 rpm, preferably 1900 rpm to 2300 rpm. In addition, the fan blade 151 is not flat, but may be curved with a predetermined or undetermined curvature, and the height difference between the lowermost end and the uppermost end of the curved fan blade 151 may be 5 mm to 30 mm. On the other hand, the diameter of the suction fan 150 may be 60 mm to 120 mm, preferably, 80 mm to 110 mm. Moreover, controlling the shortest distance between the suction fan 150 and the inner wall of the main body 110 at 1mm to 2.5mm can effectively form the suction airflow while minimizing the noise caused by the suction fan 150 .

In addition, the ratio of the vertical distance between the UV LED installation part 160 and the main body 110 to the height of the main body 110 may be 1:1 to 1:2, and the UV LED installation part 160 and the capture part 170 A ratio of the spaced vertical distance to the height of the trapping part 170 may be 1:0.5 to 1:2. Within the ratio range, the insects may not be stuck to the suction fan 150, and at the same time, insects near the insect trap 1000 may be easily sucked. In this case, the vertical distance spaced apart from the upper end of the catching part by the UV LED installation part may be 3 cm to 30 cm.

Therefore, within the size range, between the insect passage portion 120 and the UV LED installation portion 160, the speed of the airflow formed by the suction fan 150 can be controlled to be 0.5m/s to 3m/s. s, preferably 0.8m/s to 2m/s, insects stop flying while not sticking to the suction fan 150, and can be efficiently caught in the catching part 170, which can prevent the insects from being caught by the suction fan 150. generated noise.

In addition, the motor 140 is installed on the lower part of the insect passing part 120, and the suction fan 150 is installed on the lower part of the motor 140. With this structure, the insect trap 1000 can be driven by the motor. 140 and the noise generated by the suction fan 150 is significantly reduced. For example, the noise measured at a horizontal distance of 1.5 m from the insect trap may be below 40 dBA.

Air Dust Collection Unit 130

Fig. 5 is a diagram showing an air dust collection unit according to an embodiment of the present invention.

The air dust collection part 130 is installed on the lower part of the main body 110, and may include the air dust collection part spokes 131, the air dust collection part side opening 132 and the air dust collection outlet 133, so that by means of the suction fan 150 The inflowing insects are discharged to the catcher 170 , and the air dust collector 130 may have a cone shape whose diameter becomes narrower as the distance from the suction fan 150 increases. That is, in order not to disperse the airflow generated by the suction fan 150, the air dust collection part 130 can be efficiently sent to the lower part of the capture part 170, preferably in a cone shape, including all The side opening 132 of the air dust collecting part enables the airflow generated by the suction fan 150 to be effectively discharged to the outside of the insect trap 1000 . The shape of the side opening 132 of the air dust collection part is not particularly limited, for example, it may be in the shape of a mesh, and the area of the hole formed by the mesh shape is preferably controlled so that insects, especially mosquitoes, cannot pass through.

Therefore, the air dust collection part 130 also includes the side port 132 of the air dust collection part whose hole size is controlled, so that the insects flowing in by the suction fan 150 can be caught in the catch part. After 170, it is impossible to escape to the outside of the insect trap 1000.

On the other hand, the ratio of the diameter of the air dust collection outlet 133 to the diameter of the suction fan 150 can be 1:2 to 1:9, preferably 1:3 to 1:5. Within the ratio range, wind speed control by means of the suction fan 150 can be easily performed.

capture unit 170

Fig. 6 is a diagram showing a trapping portion of an insect trap according to an embodiment of the present invention.

Referring to FIG. 6 , the capturing part 170 may include a mesh part 171 for air to be discharged to the outside by means of the suction fan 150 . In addition, the mesh portion 171 may include mesh portion holes 173 formed between adjacent mesh portion spokes 172 for the airflow formed by the suction fan 150 to be discharged to Outside the trapping part 170, in order to make the air flow smoothly while the trapped insects cannot escape, the diameter of the mesh hole 173 may be 1 mm to 3 mm.

In addition, the ratio of the sum of the areas of the insect passing holes 121 to the sum of the areas of the mesh holes 173 may be 1:1.2 to 1:3.0, preferably 1:1.8 to 1:2.5. Within the range of the ratio, even if insects are trapped and accumulated in the trapping portion 170 to 1/2 of the volume of the trapping portion 170 , the flow of the air discharged to the outside of the insect trap 1000 will not be hindered. In this case, preferably, the height of the insect repellent can be 8cm to 50cm.

That is, the trapping part 170 can effectively spit out the airflow generated by the suction fan 150 to the outside of the insect trap 1000, and therefore, the trapped mosquitoes will be dried to death in the trapping part 170.

UV LED mounting part 160

Referring to FIGS. 1 to 3 , the UV LED mounting part 160 may be in the form of a plate. Specifically, the UV LED installation part 160 can be formed in a shape and/or size similar to the main body 110, for example, when the main body 110 is circular, the UV LED installation part 160 can be similar to the body 110. The main body 110 is in the shape of a circular plate of similar size.

Therefore, the UV LED installation part 160 is restricted so that the airflow formed by the suction fan 150 flows into the space formed between the UV LED installation part 160 and the main body 110, so that the air flow into the UV LED installation part 160 can be controlled. The efficiency of airflow generation in the insect trap 1000 is improved, and as a result, the number of rotations of the suction fan 150 does not need to be unnecessarily high, so that the generation of noise can also be minimized.

On the other hand, a bracket 180 that separates and supports the UV LED installation part 160 may be disposed on the main body 110, so that insects do not flow into the space between the main body 110 and the UV LED installation part 160. , a UV LED module 161 is attached to the UVLED installation part 160, and a UV LED installation part umbrella cover 162 may be additionally installed.

In addition, the shape and number of the brackets 180 are not particularly limited, but from the angle of minimizing the area where the space where insects flow in is limited by the brackets 180 while stably supporting the UVLED mounting part 160 In other words, the two brackets 180 can be retrofitted in opposite directions.

The UV LED mounting part 160 can control the height of the bracket 180 so that the UV LED mounting part 160 is vertically spaced from the main body 110 by 1 cm to 10 cm, preferably 2 cm to 5 cm, if the distance is shorter than 2 cm, If the hole for the insects to flow in is too small, the efficiency of insect capture may be low. If the distance is longer than 5 cm, the airflow formed by the suction fan 150 cannot form sufficient strength, and the problem of low insect capture efficiency may occur.

Therefore, if insects are attracted by ultraviolet rays and approach the insect trap 1000, the insects can flow into the space between the main body 110 and the LED installation part 160 by means of the suction airflow formed by the suction fan 150, and pass through the space between the main body 110 and the LED installation part 160. The insect passing part 120 and the suction fan 150 are caught by the catch part 170 at the lower part of the air dust collecting part 130 .

If referring to Fig. 3, the UV LED module 161 can be installed under the UV LED installation part 160, as shown in Fig. After the upper canopy 162 is disassembled, the UV LED module 161 can be inserted into the lower part from the upper part of the UV LED installation part 160, and the UV LED module 161 can be mounted. In addition, the UV LED module 161 mounted on the UV LED installation part 160 may be electrically connected to a power source.

As far as the insect trap 1000 according to an embodiment of the present invention is concerned, the UV LED module 161 can be additionally installed on the UV LED installation part 160 so as to irradiate light in a direction horizontal to the ground. When insects fly, they stay at a height of about 1.5m from the ground for the longest time. Therefore, when the insect trap 1000 is installed at a height of about 1.5m from the ground, the UVLED module 161 irradiates it horizontally to the ground. With light, insects are strongly stimulated and can be effectively attracted to the insect trap 1000 .

In addition, as shown in Figure 3, the UV LED installation part canopy hook 163 is additionally installed above the UV LED installation part canopy 162. When used outdoors, the insect trap 1000 can be hung on a 1.5m high Twigs etc. and conveniently used.

The UV LED installation part 160 is formed in a manner corresponding to the UV LED module 161, and is equipped with a UV LED module cover to protect the UV LED module 161, which can prevent the UV LED module 161 from being damaged by external dust or insects. In order to avoid damage caused by approaching, it is preferable that the UV LED module cover is transparent.

The UV LED module cover is processed into various shapes so as to function as a lens for diffusing or focusing light emitted from the UV LED module 161 in a predetermined direction. As an example, the UV LED module cover may include materials such as glass and quartz. Compared with glass, quartz, etc., polymers with good formability, easy handling, and good durability can also be used, but in terms of molecular structure, polymers exist around the nucleus and rely on electrons with a resonance frequency corresponding to UV The cloud (electron cloud) absorbs light with a wavelength below 400nm (ultraviolet wavelength region), so not only the light transmittance will be significantly reduced, but also the material itself will be degraded by ultraviolet rays, so polymers are generally not used as the UV LED module cover.

However, PMMA (poly methyl methacrylate), which has a high monomer ratio of more than 80%, is mainly composed of carbon and hydrogen, which makes the electron cloud thin and thus has high UV transmittance. Therefore, this material can be used to form the UV LED module cover.

In addition, a fluorine-based polymer that is a stable substance that does not react with ultraviolet rays can also be used. As an example, since the ultraviolet transmittance of fluorine-based polymers is lower than that of quartz or PMMA, it is preferable to make them relatively soft and thin. That is, in order to use fluorine-based polymers as the UV LED module cover, the ultraviolet transmittance should be considered. As far as fluorine-based polymers are concerned, since the ultraviolet transmittance is lower than that of quartz or PMMA, the thinner the thickness, the greater the ultraviolet transmittance. The higher the pass rate, but if the thickness of the UV LED module cover is made thinner, there is a fear that it will be easily broken even with a small impact due to the brittleness of the polymer. Therefore, it is preferable that the material itself is made of a soft soft material, so that Reduced brittleness.

On the other hand, although not shown in FIG. 3 , the UV LED mounting part 160 may be attached or coated with a material capable of reflecting UV irradiated by the UV LED module 161 underneath. The material capable of reflecting the UV is not particularly limited, and materials such as silver or aluminum may be attached, a silver or aluminum film may be coated on the lower surface of the UV LED mounting part 160, and various forms for scattering the irradiated light may be added. Zigzag or embossed pattern.

In addition, referring to FIG. 1 to FIG. 3 , on the UV LED installation part 160 , a UV LED installation part canopy 162 that is further extended in the horizontal direction than the UV LED installation part 160 may be installed. The form and material of the UV LED installation part umbrella cover 162 are not particularly limited, and can be the same material and form as the UV LED installation part 160. For example, when the UV LED installation part 160 is circular, the The UV LED mounting portion canopy 162 may have the same center as the UV LED mounting portion 160 and a longer diameter.

Preferably, the diameter of the UV LED mounting part canopy 162 can be formed longer than the diameter of the UV LED mounting part 160 by 3.5cm to 7cm, when the diameter of the UV LED When the long diameter part of the LED installation part 160 is shorter than 3.5 cm, the airflow formed by the suction fan 150 will not concentrate on the side or below but disperse. When the diameter of the UV LED installation part umbrella cover 162 is smaller than When the long-diameter part of the UV LED mounting part 160 is longer than 7 cm, there may be a problem of unnecessarily blocking the amount of light irradiated by the UV LED module 161 . Specifically, in the range where the diameter of the UV LED installation part 160 is 8 cm to 20 cm and the diameter of the UV LED installation part umbrella 162 is 10 cm to 25 cm, the diameter of the UV LED installation part umbrella 162 can be It is formed to be 3.5 cm to 7 cm longer than the diameter of the UV LED mounting part 160 .

In addition, as far as the insect trap 1000 according to an embodiment of the present invention is concerned, when the diameters of the UV LED installation part 160 and the UV LED installation part canopy 162 are within the stated numerical range, by means of the In the area formed by the first area extending vertically downward and the second area extending horizontally from the main body 110 of the UV LED mounting part canopy 162, the speed of the airflow formed by the suction fan 150 is formed as follows: 0.5m/s to 3m/s can form the optimum wind speed for mosquitoes to stop flying and flow into the insect trap 1000 .

On the other hand, as mentioned above, the UV LED installation part 160 is located at a distance of 2 cm to 5 cm from the main body 110, and at the same time, the diameter of the UV LED installation part canopy 162 is controlled, so that by means of The airflow generated by the suction fan 150 is maintained without being affected by external wind or the like, and insects attracted by the irradiated light can be stably sucked into the insect passing portion 120 .

UV LED modules 161, 261, 361

In another example, the first dimming control unit 11 can be configured to select a dimming level according to a preset dimming level selection algorithm every 10 seconds, and control the first dimming level during 10 seconds according to the selected dimming level. Light emission of the light emitting unit 10 . For example, the dimming level selection algorithm can be structured to increase the dimming level by 10% every 10 seconds from a 10% dimming level to a 100% dimming level, and after reaching the 100% dimming level, in turn, to increase the dimming level by 10% every 10 seconds.
