Description

Insecticide Fumigation to Attract Mosquitoes with Ultraviolet Light Emitting Diode

One pesticide fume to make.

Insecticides are chemicals that have a high effect of killing insects to be killed, such as mosquitoes, while minimizing damage to the human body. Insecticides commonly used in homes target mosquitoes, cockroaches and ants.

Particularly, in the case of a mosquito repellent, the mosquito repellent in the container in the form of a pad or a liquid in which the mosquito repelled is removed from the method of spraying an aerosol-type mosquito repellent or making a mosquito repellent. This method is particularly suitable for home use because the mosquitoes spread slowly and have little or no smell and can be used slowly and continuously throughout the night.

However, the electric fumigated mosquito insecticide has a limited effect on the insecticidal effect, such as a person who sleeps with a fume machine still bites the mosquito because the insecticidal effect is reduced at a location far from the fume machine.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

The present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, only this embodiment to make the disclosure of the present invention complete and to those skilled in the art to fully understand the scope of the invention It is provided to inform you.

In addition, the terms "rear part" and "front part" of the housing used in the present invention may be variously changed according to the installation environment of the insecticide fumigator according to an embodiment of the present invention, for example, relatively wall The facing or curved face may refer to the "rear part", and the facing or curved face toward the opposite direction of the wall may refer to the "front face part".

1 is an exploded perspective view of an insecticide fumigator according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the insecticide fumigator of FIG. 1.

The fumigation of the present invention is fixed to the drug (90) is fitted into the housing 10 forming the overall appearance, the heating unit 50 is installed in the housing 10 to heat the fumigation part 91 of the drug (90) In this case, when power is supplied to the heating unit 50 through the plug 20, the mosquito insecticide contained in the fume unit 91 is operated by gradually evaporating and spreading in the air. The medicine 90 is in the form of a liquid mosquito insecticide inside the container, the lower end of the fumigation is contained in the liquid insecticide inside the container, when the upper part of the fumigation is heated, the mosquito insecticide in the fumigation evaporates the container by the capillary phenomenon The liquid mosquito insecticide contained inside continues to climb the fumigation.

The present invention is a technical idea that the mosquito insecticide evaporated in the fumigation unit attracts mosquitoes into the space around the fume, which is the area where the concentration is the highest in the air, thereby killing the attracted mosquitoes in the space around the fume.

To this end, the present invention, at a position close to the fumigation hole 14, which is a passage through which the insecticide fumigation fumigation in the fumigation unit 14, irradiates at least the light attracted mosquitoes toward the upper space of the fumigation, fumigation far away from the fumigation Mosquitoes that were not affected by insecticides are attracted around the fumigator, especially the upper space.

As a light source 70 for irradiating light attracting mosquitoes well, an ultraviolet light emitting diode 71 is used in the present invention. Since the ultraviolet light emitting diode 71 has a form in which the amount of light is concentrated around the peak wavelength band as compared with the conventional ultraviolet lamp, that is, the spectrum half width is narrower, light having a specific effect such as mosquito attracting. It was confirmed through the following experiment that it is particularly advantageous when this need to intensively emit light.

Hereinafter, the results of experiments using insect repellents using the insect repellents equipped with ultraviolet light emitting diodes and conventional commercial BL (black light) lamps will be described. First, the specifications of the two light sources are shown in the table below.

	Voltage [V]	Current [A]	Power [W]	PF	Wp [nm] peak wavelength	Fw [nm] Spectrum Half width	Φe [mW] Radiant Flux	Φv [lm]
UV LED (Ultraviolet Light Emitting Diode)	220.1	0.034	4.98	0.66	367.94	9.24	759.19	5.7
B / L (Black Light) lamp	220.1	0.247	6.4	0.12	365.88	18.36	528.8	8.37

Both light sources were configured similarly around the peak wavelength of 365nm, so the experiments below were conducted to see how much difference other than the peak wavelength would make the mosquito attracting effect. Comparing the specifications of the two light sources, the spectrum half width of the spectral peak is only half of the BL lamp of the ultraviolet light emitting diode, and the intensity of the ultraviolet light of the visible light is 133 mW / lm. It can be seen that the lamp is more than twice as large as 63mW / lm.

Two experiments were conducted in an outdoor barn with these light sources. The number of trapped individuals attracted overnight was as follows.

Specie	Common name (infectious disease)	Collection		Average capture rate (standard deviation)
		B / L	UV LED	B / L	UV LED
Aedes vexans	West Nile Fever	10	70	12.5 (-)	87.5 (-)
Anopheles sinensis	Chinese Spotted Mosquito (Malaria)	296316	1,0282,500	16.8b (7.9)	83.2a (7.9)
Culex pipiens	West Nile Fever	118104	497536	17.8b (2.1)	82.2a (2.1)
Cx. tritaeniorhynchus	J. Encephalitis	687452	3,3073,196	14.8b (3.4)	85.2a (3.4)
Mansonia uniforms	Spotwing Swamp Mosquito	14580	269368	26.5b (12.1)	73.5a (12.1)
Total		1,247952	5,1086,600	16.1b (4.9)	83.9a (4.9)

As can be seen from the above test results, the case of using the insect repeller equipped with the ultraviolet light emitting diode has a collection efficiency more than five times than the case of using the conventional BL lamp repeller. These experimental results indicate that ultraviolet light emitting diodes are much narrower in spectrum half width than conventional ultraviolet lamps, so that they can intensively irradiate ultraviolet rays in a desired wavelength range. It is presumably due to the fact that the ultraviolet irradiation region can be concentrated at the point. That is, the present invention uses an ultraviolet light emitting diode that exhibits at least five times more mosquito attracting effects than a conventional ultraviolet lamp as a light source, and uses the directivity of the light emitting diodes to concentrate the irradiation dose of ultraviolet rays to the mosquitoes.

In general, ultraviolet rays in the near-ultraviolet (UVA) region (320 nm to 400 nm) are known to have a worm attraction effect, but it is not known about which wavelength range is particularly effective. This recognition stems from the fact that UV lamps in the UVA region have a better insect attraction effect than UV lamps in other regions. However, UV light emitting diodes have a much smaller half width than UV lamps, so it is necessary to specify which peak wavelength UV is more attractive. That is, even if the ultraviolet rays emitted from the two ultraviolet light emitting diodes emitting light of different wavelength bands are all within the UVA range, the effects of attracting mosquitoes may be different if they have different peak wavelengths. In the previous experiment, when the half width was wide and compared with the lamp which evenly irradiated UV rays of different wavelengths based on 365 nm, the mosquitoes were attracted to the insect repellent using the ultraviolet light emitting diode, which is narrower at half width, so that the ultraviolet rays around 365 nm wavelength are more concentrated. From the point of view, it can be estimated that ultraviolet light around 365nm has the highest mosquito attraction effect.

Based on the above experimental results, in the present invention, an ultraviolet light emitting diode having a peak wavelength of 365 nm is used as a light source. When the half width of the ultraviolet light emitting diode is viewed, ultraviolet rays having a peak wavelength of approximately 360 to 370 nm are expected to produce a mosquito attracting effect corresponding to the above experimental results.

According to the present invention, a substrate 72 on which the ultraviolet light emitting diode 71 is mounted is installed in the housing 10, and the ultraviolet light is irradiated directly or indirectly toward at least an upper portion of the fumigator. For the convenience of the assembly process, the housing 10 may be divided into two or more parts and manufactured. The first housing 11 and the second housing 12 are separately manufactured and then coupled to each other while accommodating various parts.

The first housing 11 may be utilized as a part in which various components are fixed in the partial configuration of the divided housing. The central portion of the first housing is provided with a chemical installation unit 19 to which the medicine 90 is coupled or separated by a screw fastening method. The central portion of the drug installation unit 19 is formed with a penetrating portion, the fumigation portion 91 of the medicine 90 penetrates it is accommodated in the inner space of the housing.

The heating part fixing member 15 is provided on the upper surface of the chemical | medical agent installation part 19 which is a position where the heating part 50 for heating the fumigation part 91 is installed. The heating part fixing member 15 is formed in the form of a protrusion protruding upwards, and the heating part 50 is inserted into the groove provided in the heating part 50 in the form of an interference fit, so that the heating part 50 is the first housing 11. Is fixed to. The fixing structure of the heating unit 50 is not limited to the interference fit method, and the assembly may be any structure that can easily fix the heating unit 50 to the first housing 11 in the assembling process. Applicable

The heating unit 50 is a toroidal annular heating element that converts electrical energy into thermal energy to heat the fumigation unit 91. The heating unit 50 is electrically connected to the power supply through the plug 20 and the wire 22 to be described later. When the medicine 90 is installed in the medicine installation unit 19, the fumigation part 91 of the upper medicine 90 is inserted into the donut-shaped heating part 50. Therefore, the heating part surrounds the fumigation part, and as a result, heat generated in the heating part is transferred to the fumigation part well.

The plug 20, which is inserted into an outlet installed on the wall and becomes a passage for receiving external power, is fixedly installed on the fastening plate 21, electrically connected to the heating unit 50 through the electric wire 22, and again connected to the electric wire 24. Is electrically connected to the substrate 72 through. The plug 20 fixed to the fastening plate 21 is manufactured in a state of being connected to the heating unit 50 and the light source 70 through the wires 22 and 24, and is fixed on the first housing 11.

The plug 20 fixes the fastening plate 21 to the plug fixing part 112 of the first housing 11. The fastening plate 21 is fitted downward from the top of the plug fixing portion 112 and fastened to each other. Next, as described above, the heating unit 50 is fixed to the first housing 11, and the substrate 72 on which the ultraviolet light emitting diode 71 is mounted is fixed to the light source fixing member 17. The first housing 11 may be made of a synthetic resin-based material having a certain elasticity, and the substrate 72 may be forcibly fitted to the light source fixing member 17 having a certain elasticity to fix its position. . The ultraviolet light emitting diode mounted on the substrate 72 is disposed to face upward.

In this state, the second housing 12 may be fastened to the first housing 11. The fastening method may be applied to various conventional methods such as screw fastening, snap-in fitting of the hook. The fumigation hole 14 is provided in the center part of the 2nd housing 12 aligned in the upper part of the fumigation part 91 of the chemical | medical agent 90 fixed to the housing. The fumigation unit 91 is arranged so as not to protrude more than the top of the fumigation hole 14, so that the user does not directly touch the top of the fumigation unit. And as shown there is a slight gap between the top of the fumigation 91 and the fumigation hole 14 so that the heated air in the interior space of the housing 10 with the pesticide fumigation through the fumigation hole 14 during the fumigation fumigation It was allowed to flow out.

When the second housing 12 is fastened to the first housing 11, the heating part support member 151 protruding downward from the bottom of the second housing 12 may lightly press the upper end of the heating part. Therefore, by combining the second housing and the first housing, it is possible to prevent the heating portion 50 from falling upward from the heating portion fixing member 15. Likewise, the light source support member 171 also gently presses the upper edge of the substrate to prevent the substrate from being separated. In addition, since the outer peripheral bottom surface of the second housing presses the fastening plate 21 of the plug inserted into the plug fixing part 112, the fastening plate 21 is also firmly fixed to the housing.

According to the present invention, the plug 20, the heating part 50, and the light source 70 are electrically connected to each other through wires, etc., and then temporarily fixed to the first housing, which is a housing of one of the divided housing parts. , Since the second housing 12 is assembled in such a manner as to be fastened to the first housing 11, the assembly process is simple. In addition, the second housing 12 is fastened to the first housing 11 and at the same time, the parts temporarily fixed to the first housing 11 are firmly fixed, thereby further reducing the number of assembly operations.

In the portion of the second housing 12 corresponding to the position of the ultraviolet light emitting diode 71 provided in the housing, a passage hole 18 is provided so as to irradiate the ultraviolet light emitted from the ultraviolet light emitting diode 71 to the outside of the housing. As shown in the drawing, it is possible to protect the ultraviolet light-emitting diode 71 by installing a protective window 80 that blocks the passage hole 18 as necessary. The protective window 80 must be a material that can transmit ultraviolet rays in the UVA region, and a high transmittance and high energy level should not be absorbed and degraded. As a suitable material, fluorine-based synthetic resins such as quartz, polymethyl metaacrylate (PMMA) having a monomer ratio of about 85% or more, and “Teflon” manufactured by “Dupont” may be used.

Of course, when the ultraviolet light emitting diode 71 is mounted in a hemispherical primary lens and a package form, the light emitting diode chip portion is protected by the primary lens, so it is possible to omit the protective window. The primary lens may be manufactured in a hemispherical shape centered on the light emitting point of the ultraviolet light emitting diode 71 to minimize the reflectance of the ultraviolet light generated at the interface of the lens.

According to the fumigation described with reference to FIGS. 1 and 2, power is applied to the heating unit 50 and the substrate 72 while the plug 20 is plugged into a wall outlet, thereby irradiating the fumigation of the insecticide and ultraviolet rays. Will happen. Since the ultraviolet rays are irradiated upward, which coincides with the direction in which the fumigation occurs, mosquitoes are attracted to the ultraviolet rays irradiated into the upper space of the fumigation, and are immediately extinguished in the upper space of the fume, which is a high concentration of insecticide.

On the other hand, at least a side surface of the housing 10 is provided with an air inlet hole 61, the air inlet hole is a housing inner space that is heated by the heating unit is emptied by the air flowing out through the fumigation unit 91, Unheated air flows in through 61. Since the light source 70 is located between the air inlet 61 and the heating unit 50, the air introduced through the air inlet 61 is minimally affected by the air heated by the heating unit 50. In contact with the cooling to allow sufficient.

In addition, the light source 70 is located in a direction opposite to the direction in which the plug 20 is installed based on the fumigation unit 91. When the fumigation is based on the fumigation, the installation direction of the plug is the rear wall. Therefore, by placing the light source 70 in front of the fumigation part, the upper part of the fumigation part irradiated with ultraviolet rays by the light source is secured even a little more. You can do it. In addition, because of this, the air inlet hole 61 is also formed in front of the housing, so that the air inlet is made smoother.

Hereinafter, other embodiments of the present invention will be described. 3 to 6 are cross-sectional views of different embodiments of the insecticide fumigator, respectively. In the description of FIGS. 3 to 6, descriptions of portions overlapping with the above-described matters may be omitted, and thus, the following embodiments will not be applied or related technologies will not be applied to the embodiments to be described below. Note that this does not mean that you did not.

First, referring to Figure 3, the fumigation according to another embodiment of the present invention is made of a form in which the upper surface of the second housing 12 is recessed toward the center. In the ultraviolet light-emitting diode 71 provided in front of the fumigation part 91, the center line c of the irradiation angle is inclined slightly backward toward the vertical line v. As shown in FIG. In addition, an ultraviolet through hole 18 is formed in the upper portion of the housing along the center line c of the ultraviolet light emitting diode 71. The angle of inclination toward the rear about the vertical line may be appropriately selected within the range of 0 degrees (the position where the center line and the vertical line coincide) to 90 degrees.

The UV light emitting diodes 71 are installed in such a way as to be inclined backward to prevent direct viewing of light emitted from the UV light emitting diodes. Near-ultraviolet rays (UVA region) with a peak wavelength of 365 nm have little effect on the human body, but it is not possible to completely rule out the possibility of eye diseases if the naked eye is exposed to it excessively. Accordingly, in the present invention, even if the ultraviolet rays are slightly biased toward the rear side, the naked eye is prevented from being directly exposed to the naked eye, and since the ultraviolet rays irradiated toward the rear reaches and scatters on the wall, the mosquitoes far away from the fumigator are ultraviolet rays. It is one technical feature to be attracted to see the scattered wall surface.

3, a shielding member 16 is provided between the heating unit 50 and the light source 70. The shielding member 16 is installed on the straight line when the heating section 50 blocks the heat transfer to the light source by radiation, that is, the position of the shielding member 16 and the heating section 50 in a straight line. do. In addition, the shielding member 16 has a position and a shape to block the air heated in the heating unit 50 from convection and heat transfer to the light source. To this end, the shielding member 16 facing the heating part has a shape that is closer to the fumigation part 91 upward. While satisfying these two conditions, if the shielding member 16 has a vane shape such as a thin guide plate as shown, the air inlet 61 formed in a direction facing the heating part based on the light source 70 Since the air introduced through the vane shape is guided and discharged through the fumigation hole 14, it is possible to increase the fumigation diffusion efficiency and to prevent the heat generated from the heating unit from convection and moving toward the light source. That is, the fumigation hole 14 functions as an air outlet hole in which air introduced into the housing through the air inlet hole is discharged after cooling the internal components.

In addition, as shown in Figure 3, by forming a separate air outlet hole 62 in the position closest to the light source 70 and the height of the portion of the housing 10, through the air inlet hole 61 After the introduced air absorbs heat generated from the light source 70 (that is, after cooling the light source), the air may move on the inclined surface of the upper part of the housing to be smoothly discharged to the outside through the air outlet hole 62. In addition, when the separate protective window 80 is not installed in the through hole 18, the heated air can be smoothly discharged through this.

Next, referring to FIG. 4, which shows another embodiment of the present invention, the light source 70 is installed at the upper end portion of the housing, and the center irradiation direction (see c) of the light source is substantially horizontally rearward. Heading up. In particular, the center of the upper surface of the second housing 12 is located below the central axis (c) of the irradiation angle of the ultraviolet light emitting diode 71, the outer surface of the upper surface of the second housing is made of a form that rises toward the outside. The rising part intersects the central axis c of the irradiation angle of the ultraviolet light emitting diode 71. On the other hand, the reflecting surface 85 in which the ultraviolet-ray is reflected well is provided in the upper surface of the housing.

When power is supplied to a fume having such a structure and the ultraviolet rays are irradiated, the ultraviolet rays irradiated upward above the central axis c reach the upper part directly on the wall where the fume is inserted, and irradiate downward below the central axis c. The ultraviolet rays are reflected from the reflecting surface 85 and the irradiation direction is changed upward to be irradiated toward the upper side and the wall side of the fume, and the ultraviolet rays irradiated side by side with the central axis c are reflected on the inclined plane crossing the central axis and upwards. Direction is switched to. Therefore, even if the central axis of the irradiation angle of the ultraviolet light emitting diode is horizontal, the ultraviolet light can be sufficiently irradiated on the upper space and the wall of the fumigator. In particular, according to the embodiment of FIG. 4, the ultraviolet light passing directly above the fumigation hole 14 has a very high illuminance, and at the inlet portion of the fumigation hole 14, since the distribution density of the fine particles of the fumigated insecticide is very high, the fine particles Ultraviolet scattering occurs on the surface of, and in particular, ultraviolet rays having a shorter wavelength than visible light scatter more easily, so that light scattered by particles is not easily seen by the human eye, but is easily visible to the mosquito eye. Therefore, according to the embodiment shown in FIG. 4, the effect of attracting mosquitoes can be further enhanced by the above-described principles.

Next, FIG. 5, which shows another embodiment of the present invention, shows that the irradiation angle of the ultraviolet light emitted from the ultraviolet light emitting diode can be limited to the through hole 18. That is, the irradiation range of ultraviolet rays irradiated forward from the ultraviolet light emitting diode 71 forward with respect to the vertical line v may be determined by the relative positions of the through hole 18 and the ultraviolet light emitting diode 71. Since the outlets installed on the wall are generally provided at a position lower than the height of the human being, the range where the ultraviolet ray is irradiated forward with respect to the vertical line (v) does not exceed 30 degrees. You can greatly reduce your chances of looking.

In addition, a reflecting surface 85 is provided at a part of the inner circumferential surface of the through hole 18 that restricts the irradiation range of ultraviolet rays irradiated toward the front with respect to the vertical line, so that it is irradiated toward the front by the shape of the through hole. By changing the direction of irradiation of the limited ultraviolet back to the rear can further increase the mosquito attraction efficiency by the ultraviolet.

Next, FIG. 6, which shows yet another embodiment of the present invention, shows a structure in which the ultraviolet light emitting diode 71 is installed when viewed from the rear side of the housing. According to this structure, when a fumigator is installed on the wall, the possibility of a person seeing the ultraviolet light emitting diode 71 with the naked eye can be significantly lowered, and the ultraviolet rays irradiated from the ultraviolet light emitting diode 71 are scattered or reflected from the wall surface, When viewed through the eyes of a mosquito, it has the same effect as indirect lighting. Therefore, even in the case of the fumigation shown in Figure 6 it can increase the attraction efficiency of the mosquito. In particular, in the case of the fumigation shown in Figure 6, by installing a secondary lens in front of the ultraviolet light emitting diode 71 installed toward the rear, the mosquito mosquitoes by widening the irradiation angle of the ultraviolet light, as well as by switching the irradiation direction of the ultraviolet light from the front to the side The attraction effect can be further enhanced.

FIG. 7 is a perspective view illustrating an embodiment of a light source used in FIG. 6, and FIG. 8 is a cross-sectional view taken along line X-X of FIG. 7. Referring to FIG. 7, the light source 70 of the embodiment illustrated in FIG. 6 has a structure in which an ultraviolet light emitting diode 71 is mounted on a substrate 72 and a lens is integrally or separately installed on the substrate 72. As shown in FIG. 6, when the ultraviolet light emitting diode is installed toward the rear, the ultraviolet light emitting diode is not concentrated on the wall immediately behind the fumigation part. The optical path should be controlled so that the ultraviolet rays emitted from 71 have the widest directivity.

 Referring to FIG. 8, when the angle from the ultraviolet light emitting diode 71 to the light path emitted from the ultraviolet light emitting diode 71 is determined based on the central axis O of the light irradiation area of the ultraviolet light emitting diode 71, a increases in a The surface profile of the secondary lens 74 is formed such that the distance r from the light emitting point of the light emitting diode 71 to the exit point E of the surface of the secondary lens 74 is gradually increased. According to this profile, as the ultraviolet light emitted from the ultraviolet light emitting diode 71 is refracted on the surface of the secondary lens 74 and emitted, the angle of the optical path is changed from a to a '(a <a'). Therefore, the ultraviolet rays emitted from the ultraviolet light emitting diode 71 become larger by the secondary lens 74 in the left and right directions on the drawing. The shape of the secondary lens 74 is such that the hemispherical balloon is pressed more flatly from above.

When the secondary lens 74 of this type is installed on the primary lens 73 mounted with the ultraviolet light emitting diode 71 in a package form, the irradiation angle of the ultraviolet light emitting diode 71 becomes larger, Ultraviolet rays can be irradiated in a form that is widely spread on the wall around the fumigation.

The secondary lens of the type described above is still concentrated in the amount of ultraviolet light irradiated to the front. Hereinafter, by irradiating the irradiation direction of the ultraviolet radiation to the front side to the maximum side, and proposes a lens form that can increase the mosquito attracting effect by irradiating the ultraviolet rays wider in the use environment shown in FIG.

9 is a perspective view illustrating another embodiment of the light source used in FIG. 6, and FIG. 10 is a sectional view taken along line Y-Y of FIG. 9. The lens shown in FIG. 9 differs from the lens in FIG. 7 in that the center portion of the lens is concavely recessed by pressing the center of the lens with a sharp pin. That is, in contrast to FIG. 7, the lens of FIG. 9 has a difference in that an area 0 <a <a1 is formed in the vicinity of the central axis O of the light irradiation area when viewed in the cross section of FIG. 10. The recessed area is inclined outwardly from the central axis O of the light irradiation area of the ultraviolet light emitting diode 71 and extends, and the inclination is gradually reduced (convex upward) as it extends outward.

Referring to FIG. 10, when there is a recessed area, the light scattering effect is greater than when there is no recessed area. That is, in the recessed area, even if total reflection or total reflection does not occur, a substantial portion of the light reaching the lens surface is reflected and its path is changed laterally. Therefore, the light concentrated near the central axis of the light irradiation area is considerably dispersed. As a result, ultraviolet rays emitted from the ultraviolet light emitting diode 71 are reflected or totally reflected from the central axis to the point A1 to become a region where the irradiation direction is changed to the side. Also, considering that there may be ultraviolet rays returned to the substrate direction by reflection or total reflection at the outer surface E of the lens, the reflective surface 75 is formed on the bottom surface of the second lens 74 or on the substrate 72. It is preferably formed. The ultraviolet rays are further dispersed by the ultraviolet rays reflected back from the reflecting surface 75.

That is, even if the ultraviolet light emitting diode 71 is installed in the position shown in FIG. 6, the secondary lens having the structure shown in FIGS. 7 and 9 can be used to widen the irradiation area of ultraviolet rays, and thus ultraviolet light emitting light. The mosquito attraction efficiency can be increased while eliminating the concern of directly seeing the diode.

FIG. 11 shows a structure in which the ultraviolet light emitting diode 71 is installed to face the front side of the housing 10 and further includes a cover 76 in front of the ultraviolet light emitting diode 71. The cover 76 is not particularly limited in shape, and the cover 76 is detachably provided in front of the ultraviolet light emitting diode 71 so that the user can easily replace the ultraviolet light emitting diode 71 and irradiate the ultraviolet light emitting diode 71. The light may be a material that is transmitted, and the surface is uneven or the cover plate (not shown) is attached or spaced in front or rear of the cover 76 so that the light can be refracted or diffused It may be in the form. That is, pests, especially mosquitoes, tend to improve the attraction efficiency when the light is refracted or diffused than when the light is directly irradiated. The light irradiated from the ultraviolet light emitting diode 71 is not directly irradiated, and the cover 76 Permeation), the light attracting efficiency of the mosquito can be improved.

For example, the cover 76 may be formed of at least part or all of the light-transmitting material, for example, a portion through which the light emitted from the ultraviolet light emitting diode 71 is transmitted is polycarbonate (PC), polyethylene terephthalate (Polyethyleneterephthalate; PET), methyl methacrylate-styrene (MS), polymethylmethacrylate (PMMA), and the like, and may include a material, and include at least one of transparent, translucent, and colored. It can be formed in color.

Therefore, the insecticide fumigator is installed such that the ultraviolet light emitting diode 71 faces forward from the front side of the housing 10 so that the light arrival area is improved, and the light is refracted or diffused by the cover 76 to prevent the mosquitoes from being moistened. While improving the light attracting efficiency, by implementing a structure in which the ultraviolet light is not directly exposed to the human eye by the cover 76, it is possible to prevent the damage caused by the continuous exposure of ultraviolet light to the naked eye, fumigation of mosquito insecticide The amount can be minimized to minimize the incidence of physical illnesses caused by fumigated pesticides.

12 illustrates a structure in which a guide rail 77 is provided to guide the ultraviolet light emitting diode 71 from at least one side of the housing 10. The ultraviolet light emitting diode 71 may move along the outer circumferential surface of the housing 10 along the guide rail 77, and may be manually adjusted by a user or may be automatically adjusted by providing a separate driving unit (not shown). . The driving unit may be implemented using a known technique such as an electric motor or a hydraulic cylinder, and may perform a function of moving the ultraviolet light emitting diode 71 or the light source 70 including the same along the guide rail 77. . That is, the insecticide fumigator can easily change the irradiation direction of the ultraviolet light emitting diode 71 as the attracting light source, so that even if the installation environment of the insecticide fumigator is changed, it is possible to maintain the high light induction efficiency of the pest, in particular the mosquito.

In addition, a cover 76 covering the guide rail 77 may be further installed in FIG. 12, and an installation form, a material, and the like of the cover 76 may be applied to the bar described above with reference to FIG. 11. In other words, the insecticide fumigator can maintain high light attraction efficiency of pests, especially mosquitoes even when the installation environment is changed, and improve the light attraction efficiency by causing the attractant light to be refracted or diffused, while also exposing ultraviolet light directly to the human eye. You can prevent it.
