Description

  The present invention relates to a pest control apparatus that captures pests attracted by a light source and controls the damage caused by these insects.

  Flying insects that enter the building cause various troubles in industry and daily life. For example, in a food factory or a restaurant, insects may be mixed into products or the like, and in retail stores, insects may fly around in the store and cause discomfort to shoppers.

  Therefore, conventionally, various insect traps have been provided in order to capture flying insects that have entered the building and control the damage caused by these insects. For example, as shown in Patent Document 1 and Patent Document 2, an insect trap that includes a light source that emits light that attracts pests and captures the pest attracted by light emitted from the light source is known.

The insect traps shown in Patent Literature 1 and Patent Literature 2 are installed at a position relatively close to the ceiling of the wall surface, as shown in FIG. 7, for example. This type of insect trap 105 is generally arranged so that most of the light from the light source 103 is emitted in the direction of the ceiling surface. Many flying insects, including flies, have the habit of flying upward and are often localized on the ceiling surface. By installing the insect trap 105 in the vicinity of the ceiling surface, localization is performed on these ceiling surfaces. It is expected that insects will be captured effectively. In addition, when light is emitted in the direction of the ceiling surface, the light is reflected from the ceiling surface and reaches the lower part of the room, and insects flying below can be attracted. The attraction effect increases.

  However, the insect traps shown in Patent Document 1 and Patent Document 2 described above are generally installed at a height that can be reached by a person for lamp replacement of the light source, maintenance of the adhesive sheet, and the like. Therefore, for example, when these insect traps are installed in a room with a high ceiling, light is not easily reflected by the ceiling surface, so that the light does not reach the lower part of the room sufficiently. Among flying insects, there are a certain number of insects that fly only near the floor because of their low flying ability or due to their habits. Therefore, the trapping device installed at a high position like the trapping devices shown in Patent Document 1 and Patent Document 2 described above has a low effect of attracting insects flying below. In addition, when the insect trap is installed near the ceiling surface, the light reflected from the ceiling surface can be directed downward in the room, but the ceiling surface portion irradiated with light (the shaded area in the figure) In some cases, insects are attracted intensively, and the ceiling may become dirty due to collision of these insects with the ceiling surface.

  The present invention solves the above-mentioned problem, regardless of the installation position of the insect trap and the height of the ceiling surface, can effectively attract and capture insects flying above and below the room, Another object of the present invention is to provide a pest control device that can suppress ceiling dirt caused by insects attracted by light.

The invention of claim 1 includes a light source that attracts insects, a capture unit that captures insects attracted by the light source, a housing that houses the light source and the capture unit, and a housing that houses the light source and the light source. A pest control device using an insect trap equipped with an opening that emits the light of the above-mentioned, projecting forward from the upper end of the opening, and of the light emitted upward from the opening A shielding portion that shields , the opening is provided on a surface of the housing facing the attachment surface of the insect trap, and the protruding length of the shielding portion is longer than the length from the upper end to the lower end of the opening. It is configured to be long .

  According to a second aspect of the present invention, in the pest control apparatus according to the first aspect, the surface of the shielding part has a reflection characteristic of reflecting a part or all of the light emitted from the opening.

According to a third aspect of the present invention, in the pest control apparatus according to the first or second aspect , a through hole is formed in the shielding portion.

According to a fourth aspect of the present invention, in the pest control apparatus according to any one of the first to third aspects, the distal end portion of the shielding portion is located above the base portion of the shielding portion.

  According to invention of Claim 1, the light which goes upwards among the lights radiate | emitted from the opening part of an insect trap is shielded by the shielding part, The one part reflects downward. Therefore, regardless of the position of the insect trap and the height of the ceiling surface, the light reaches the lower part of the pest control device, so that insects flying under the room are also attracted effectively. Moreover, since the light toward the ceiling surface is shielded, insects are not attracted to and collide with the ceiling surface, and the ceiling surface is not soiled.

  According to the invention of claim 2, since a lot of light reaches the lower part of the pest control apparatus, the attraction effect for the insects flying below is enhanced.

According to the invention of claim 3 , since a part of the light irradiated to the shielding part passes through the shielding part and reaches the upper part of the pest control apparatus, the insect flying right above the pest control apparatus Can be effectively attracted.

According to the invention of claim 4, the range in which the light is blocked by the shielding portion is narrowed, and light is irradiated to a wider range, and the insect attracting effect is improved.

  A pest control apparatus according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. The pest control apparatus 1 according to this embodiment includes a light catcher 5 having a light source 3 that attracts the insect 2 and a capture unit 4 that captures the insect 2 attracted by the light source 3. The insect trap 5 includes a housing 50 that houses the light source 3 and the capturing unit 4, and an opening 51 that is provided in the housing 50 and emits light from the light source 3. Moreover, the pest control apparatus 1 of this embodiment is provided with the shielding part 6 which shields the light which goes upwards among the lights radiate | emitted from the opening part 51 of the insect trap 5. FIG. In the figure, light emitted from the light source 3 is indicated by a broken-line arrow.

  The insect trap 5 is a general-purpose insect trap, and includes the light source 3, the capture unit 4, and the housing 50. If the housing 50 has an opening 51 for emitting light from the light source 3, The configuration and shape are not particularly limited. The light source 3 is a general-purpose insect trap fluorescent lamp (UV-A lamp) or the like, and preferably a light source that emits light having a high insecticidal effect with a wavelength of about 340 to 380 nm. Although the capture unit 4 is not particularly limited, the pest control apparatus 1 according to the present embodiment is applied indoors, and therefore is not of the electric shock type and the like, but captures the pest 2 attracted by the light source 3 with an adhesive sheet. A capture part is preferred.

  The shielding part 6 is a thin plate material arranged so as to protrude forward from the upper end of the opening 51 of the insect trap 5. The shield 6 may be formed integrally with the housing 50 of the insect trap 5, but it is desirable that the shield 6 be removable for maintenance or the like. The thin plate material used for the shielding part 6 is not particularly limited as long as it has a predetermined strength and is made of a material that does not transmit light. For example, a thin plate made of a stainless plate or a resin material is used.

  The pest control apparatus 1 of the present embodiment is installed at a position that is at least higher than the height of the person so that the forwardly shielding part 6 does not hinder the traffic of the person, but the replacement of the light source 3 and the capturing part 4 It is desirable to be installed at a height that can be reached by the user so that maintenance can be performed. The pest control apparatus 1 is preferably installed in the vicinity of the chamber opening 7. If it carries out like this, since the insect 2 which invaded the room will be caught quickly, it will be prevented that the insect 2 flies indoors and causes various harm.

  In the pest control apparatus 1 of the present embodiment, among the light emitted from the opening 51 of the insect trap 5, the upward light is shielded by the shielding unit 6, and a part of the light is reflected downward. Therefore, regardless of the installation position of the insect trap 5 and the height of the ceiling surface, the light emitted from the light source 3 reaches the lower part of the room, and the insects 2 flying in the lower part of the room are effectively attracted. . Further, since the shielding unit 6 is irradiated with a large amount of light, the insect 2 that moves upward is localized around the shielding unit 6 and is easily captured by the capturing unit 4. Furthermore, since the light toward the ceiling surface is shielded, the ceiling is not contaminated by insects colliding with the ceiling surface.

  The surface of the shielding part 6 is preferably formed so as to have a reflection characteristic that reflects part or all of the light emitted from the opening 51. Thus, in order for the surface of the shielding part 6 to reflect part or all of the light, for example, the shielding part 6 may be formed of an aluminum plate, or a shielding made of a resin material or the like. The surface of the part 6 may be subjected to a surface processing treatment such as aluminum deposition or application of a white paint having a high light reflectance.

  Hereinafter, the insect trapping experiment conducted in order to investigate the pest control effect by the pest control apparatus 1 of this embodiment is demonstrated. In this insect trapping experiment, the insect pest control apparatus 1 (with a black shielding part 6 having a low light reflectance on the insect trap 5 at the same height position on the wall surface in a room where flying insects can enter from outside the room. Example 1), a pest control apparatus 1 (Example 2) provided with a white shielding part 6 having a high light reflectance in the insect trap 5 and an insect trap 5 not provided with the shielding part 6 (Comparative Example 1 and Comparative Example 2) Were installed, and the number of insects captured by each capturing unit 4 after a predetermined time was calculated. In addition, about the said Example 1 and the comparative example 1, and the said Example 2 and the comparative example 2 were experimented in the same period. The results are shown in Table 1.

  In the results shown in Table 1, the pest control apparatus 1 (Example 1) including the black shielding part 6 and the pest control apparatus 1 (Example 2) including the white shielding part 6 include the shielding part 6. In contrast to the insect traps 5 (Comparative Example 1 and Comparative Example 2), the number of traps is three times or more, and it was found that the provision of the shielding part 6 can effectively trap insects.

  Moreover, according to said result, the insect pest control apparatus 1 (Example 2) provided with the white shielding part 6 has more insect trapping numbers than the insect control apparatus 1 (Example 1) provided with the black shielding part 6. It was shown that. The white shield 6 can reflect more light emitted from the light source 3 than the black shield 6. For this reason, when the pest control apparatus 1 is provided with the white shielding portion 6, a lot of light reaches the lower part of the pest control apparatus 1, so that the attracting effect on the flying insects below is enhanced.

  In this embodiment, the example which provided the shielding part 6 in the wall-mounted insect trap 5 was shown, However, The modification of this embodiment is demonstrated with reference to FIG. 3 below. In this modification, the shielding part 6 is provided above the stationary insect trap 5. When the pest control device 1 according to this modification is placed at a low position, for example, on the floor surface, the shielding unit 6 shields the light emitted upward, so that the light attracting the insect enters the human eye. It is possible to effectively capture the insects 2 in the vicinity of the floor surface while avoiding them.

  Next, a pest control apparatus according to the second embodiment of the present invention will be described with reference to FIG. In the pest control apparatus 1 of this embodiment, the insect trap 5 is installed above the chamber opening 7, and the horizontal width of the shielding portion 6 is formed larger than the horizontal width of the chamber opening 7. The shield 6 is preferably formed so as to surround the insect trap 5. As described above, when the insect trap 5 is provided above the room opening 7 which is an invasion path of the insect 2 into the room, a large number of insects 2 are attracted and captured immediately after entering the room from the room opening 7. it can. Moreover, since the insect 2 can be localized around the shielding part 6, not only the capture efficiency of the insect 2 is improved but also the insect 2 can be prevented from flying around the room. Furthermore, by providing the shielding part 6 above the insect trap 5, the light emitted upward from the insect trap 5 is reflected by the shielding part 6 and reaches the lower part of the insect trap 5, thereby attracting the insect 2. Is further increased.

  Next, a pest control apparatus according to the third embodiment of the present invention will be described with reference to FIGS. In the pest control apparatus 1 of the present embodiment, through holes 61 and 62 are formed in the shielding part 6. Other configurations are the same as those of the first embodiment. The through holes 61 and 62 may be provided with a large number of circular holes as shown in FIG. 5 (a), or may be provided with a plurality of linear cuts as shown in FIG. 5 (b). Also good. The shape and number of the elements are such that the installation environment of the insect pest controlling apparatus 1 and the shielding part 6 are such that the function of the shielding part 6 that shields light irradiation on the ceiling surface and reflects the light below the pest controlling apparatus 1 is not impaired. It is determined appropriately according to the size and the like.

  According to the pest control apparatus 1 of the embodiment, a part of the light irradiated on the shielding part 6 passes through the shielding part 6 and reaches the upper part of the pest control apparatus 1. It is possible to effectively attract the insects 2 flying right above.

  Next, a pest control apparatus according to the fourth embodiment of the present invention will be described with reference to FIGS. In the pest control apparatus 1 of the present embodiment, the distal end portion 63 of the shielding portion 6 is disposed so as to be positioned above the base portion 64 of the shielding portion 6. Other configurations are the same as those of the first embodiment. In the pest control apparatus 1 of the present embodiment, the range in which light is blocked by the shielding unit 6 is narrowed, so that light is irradiated to a wider range, and the attracting effect of the insect 2 is improved. Further, as shown in FIG. 6B, the tip portion 63 of the shielding portion 6 may be formed to be bent downward. If it carries out like this, the insect 2 attracted to the lower surface of the shielding part 6 comes to be captured more efficiently.

  The present invention is not limited to the above-described configuration, and various modifications can be made. For example, a part of the opening 50 may be provided with an optical filter or the like that cuts light of a specific wavelength out of the light emitted from the light source 3, and the blueness of the light unique to the insect light may be reduced.
