Here, openings 51a and 51b are formed on the front and rear surfaces of the housing 5 for emitting the light emitted from the lure light source 2 and the light reflected by the reflecting mirror units 4a and 4b to the outside of the instrument. .

  2A and 2B show the detailed configuration of the insect trap 1, FIG. 2A is a front view of the insect trap 1, and FIG. 2B is a sectional view taken along the line AA in FIG. The enticing light source 2 has a horizontally long straight tube shape and is disposed at a substantially central portion inside the housing 5, and is attached to two socket portions 52 a and 52 b provided on the inner side surface of the housing 5. The insect attracting light source 2 is a general-purpose insect trap light source (UV lamp), and the light emitted from the insect attracting light source 2 includes light having a high insect attracting effect based on the traveling light curve or the visibility curve of the insect, Specifically, ultraviolet light having a wavelength of around 365 nm is mainly contained, and a lot of ultraviolet light having a wavelength of 300 to 500 nm is contained. Insect light source 2 is not particularly limited as long as it emits the above-described ultraviolet light. Examples of types of insect light source 2 include a fluorescent lamp, a cold cathode lamp, a mercury lamp, and a xenon lamp. . Further, the insect attracting light source 2 may be provided with a filter for adjusting the wavelength component and the light amount of the emitted light.

  The reflecting mirror unit 4a is provided in front of the lure light source 2, and includes reflecting mirrors 41 and 42 that are arranged to face each other in the vertical direction with the lure light source 2 as a substantial center. The reflecting mirror unit 4b is provided behind the insect attracting light source 2, and is composed of reflecting mirrors 43 and 44 which are arranged to face each other as described above. The reflecting mirrors 41 and 42 are arranged so that the interval between the reflecting mirrors 41 and 42 is gradually decreased as the distance to the attracting light source 2 approaches, and the reflecting mirrors 43 and 44 are similarly configured.

  The discharge part 3a is provided on the side of the reflecting mirrors 41 and 42 where the attracting light source 2 is disposed, and the discharging part 3b is provided on the side of the reflecting mirrors 43 and 44 where the attracting light source 2 is disposed. 3a and 3b are attached to attachment grooves (not shown) formed in the above-described socket portions 52a and 52b via the insulator 30. Each of the discharge parts 3a and 3b was arranged at a substantially constant interval until the length of the attracting light source 2 became approximately the same, and had a plurality of grids 31 having conductivity and a conductivity connecting the plurality of grids 31. The base 32 is configured, and one end of the base 32 is connected to a high voltage generator 53 provided in the housing 5. In the state where the voltage is applied between the grids 31 by the high voltage generator 53, the discharge units 3a and 3b are attracted to the light from the insect attracting light source 2, and the insects 11 approaching the discharge units 3a and 3b enter the grid 31. When contact is made, the insect 11 is subjected to electric shock by electric discharge.

  Here, in the present embodiment, the grid length in the discharge parts 3a and 3b is about 20 to 40 mm, which is the same as or less than the tube diameter of the attracting light source 2, and the grid interval is about 5 to 10 mm. Yes. The maximum value of the voltage applied between the lattices 31 is 7000 V or less, and the effective value of the voltage is 4000 V or less. In addition, in a conventional electric shock type insecticidal device configured to cause a bug to die by a single electric shock, the grid length is set to about 150 to 300 mm, the grid interval is set to about 30 mm, and applied between the grids. The voltage value is about 4000V to 8000V. Below the discharge units 3a and 3b, a capture unit 6 is provided for capturing the insects 12 that have received electric shock from the discharge units 3a and 3b.

  The capture unit 6 is accommodated in a space constituted by the reflecting mirrors 42 and 44, and is provided at the bottom of the housing 5 so that the user can easily discard the insect 13 captured by the capture unit 6. The two mounting brackets 54 are detachable from the housing 5. The capture unit 6 has an entrance 61 through which the insect 12 that has received the electric shock passes, and the structure of the entrance 61 is a revolving door type structure that automatically rotates at a predetermined timing. The above structure is connected to the revolving door 62 and the revolving door 62 that is rotatably supported on the inner side surface of the housing 5 and has a cross section of a substantially + shape so that the inlet 61 can be sealed when stopped. When the discharge parts 3a and 3b give an electric shock to the insect, the rotary door 62 is rotated half-turn by the rotation of the motor, and the electric insect 12 that has received the electric shock is sent into the inside of the catching part 6. It is like that. The capturing unit 6 is filled with an insecticidal solution 63 that can immediately kill the insect 13 sent into the capturing unit 6.

  Next, a specific configuration of each part constituting the reflecting mirrors 41, 42, 43, and 44 will be described. Since the configuration of each part is the same in each of the reflecting mirrors 41, 42, 43, and 44, description will be given here using the reflecting mirror 42 positioned in front of and below the insect attracting light source 2. FIG. 3 shows a detailed configuration of the reflecting mirror 42. The reflecting mirror 42 is provided on the back surface of the transparent member 45 made of a transparent material 45 that is a reflective surface that reflects the light 47 emitted from the insect light source 2 and outputs the reflected light 48, and the transparent member 45. The mirror surface member 46 is used. The reflectance of the transparent member 45 is adjusted so as to become lower as the distance from the attracting light source 2 increases. As a method for adjusting the reflectance, when a semi-transparent paint is applied to the surface of the transparent member 45, the method of adjusting the shading of the coating, or by combining a plurality of members having different reflectances, the transparent member 45 is adjusted. The method of configuring is mentioned. Further, the transparent member 45 has a light guide characteristic that takes in the light 49 emitted from the insect attracting light source 2 from the end portion on the side where the light source is arranged and guides the light 49 to the inside. The mirror member 46 reflects the light 50 guided into the transparent member 45. The amount of light 50 guided to the inside of the transparent member 45 leaks out from the surface of the transparent member 45, that is, the amount of emission of the guided light 50 from the surface of the transparent member 45 increases as the insect light source 2 approaches. It has been adjusted to be. As a method of adjusting the injection amount, there is a method of adjusting the size of the area to be subjected to the mirror surface treatment when the surface of the transparent member 45 is subjected to a mirror surface treatment such as plating, vapor deposition or sputtering. In addition, as other methods, the method of adjusting the shade of the coating as described above, or by attaching a transparent plate made of another material having a different refractive index to the surface of the transparent member 45, the total reflection and refraction of light are repeated. A method of emitting a predetermined amount of light is conceivable.

  Next, the operation of the insect trap 1 configured as described above will be described with reference to FIG. Here, it is assumed that the insect attracting light source 2 is turned on when the power of the insect trap 1 is turned on, and a high voltage is applied between the grids 31 of the discharge units 3a and 3b. In addition, as a time slot | zone when the power supply of the insect trap 1 is turned on, it is desirable from the evening when the behavior of insects becomes active to the dawn. When the attracting light source 2 is turned on, the insects 14 around the instrument are attracted by the light emitted from the attracting light source 2 and approach the vicinity of the instrument. Here, since each of the reflecting mirrors 41 and 42 and the reflecting mirrors 43 and 44 is arranged so as to be relatively gradually reduced as it approaches the attracting light source 2, the light emitted from the attracting light source 2 is widely lost without loss. Irradiated.

  The insect 15 approaching the vicinity of the instrument passes through the openings 51a and 51b of the housing 5 and approaches the discharge portions 3a and 3b. Here, the amount of reflected light from the transparent member 45 of the reflecting mirrors 41, 42, 43, and 44 and the amount of light guided to the inside of the transparent member 45 from the surface of the transparent member 45 are the attracting light source 2. Since the number of insects increases as it approaches, the closer the insect light source 2 is, the brighter it feels. Therefore, the insect 15 approaching the vicinity of the instrument is effectively guided to the discharge parts 3a and 3b.

  The insect 11 approaching the discharge parts 3a and 3b receives electric shock caused by the discharge when it comes into contact with the grid 31 of the discharge parts 3a and 3b. Here, as described above, the distance between the reflecting mirrors 41 and 42 and the distance between the reflecting mirrors 43 and 44 are arranged so as to be relatively gradually reduced as the insect attracting light source 2 is approached. As it gets closer to the light source 2, it becomes smaller and the insects cannot fly freely in the vicinity of the discharge portions 3a, 3b. Therefore, it becomes possible for the discharge parts 3a and 3b to give multiple electric shocks to the approaching insect 11, and the insect 12 that has received the electric shock will be paralyzed or died.

  The insect 12 that has been paralyzed or died due to the electric shock is sent into the inside of the capture unit 6 when the rotary door 62 of the entrance 61 rotates. The insect 13 sent into the capture unit 6 is immersed in the insecticidal solution 63 filled in the capture unit 6, and the paralyzed insect among the insects 13 dies. Therefore, the insect 13 sent into the capture unit 6 does not run backward from the entrance unit 61 and escape from the capture unit 6. Moreover, even if the insect captured by the capture unit 6 is not dead, it is difficult for the insect to escape from the capture unit 6, so that the insect can be killed over time.

  As mentioned above, according to the insect trap 1 which concerns on this embodiment, since it becomes possible to give the electric shock multiple times with respect to the insect 11 which the discharge parts 3a and 3b approached, the voltage applied to the discharge parts 3a and 3b Even if it is relatively small, insects can be paralyzed or killed and captured. Therefore, the electric shock sound generated when the discharge parts 3a and 3b give electric shock can be reduced.

  In addition, this invention is not restricted to the structure of the said embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, instead of filling the capture unit 6 with an insecticidal solution, a crushing mechanism for crushing insects may be provided inside the capture unit 6. Further, when the light guide characteristics as described above are not added to the transparent member 45 of the reflecting mirrors 41, 42, 43, and 44, as a method for adjusting the reflectance of the transparent member 45, mirror reflection of aluminum, stainless steel, or iron is performed. A method of performing halftone dot printing with different densities on the plate can be mentioned. Also, instead of adjusting the reflectance of the transparent member 45, the surface of the transparent member 45 is subjected to a roughening process that changes the light diffusivity so that the brightness value of the surface decreases as the distance from the insect light source increases. May be.
