However, since the insect trap according to the background art is configured to attract insects by actively radiating light around the trap, it is necessary to control the amount of light to the cultivation target. In house cultivation, if it is installed near the cultivation target, there is a problem that light emitted from the insect trap affects the cultivation target.
In addition, when the insect trap is installed in the vicinity of the cultivation target, moisture supplied to the cultivation target adheres, and the adhesiveness of the adhesive member, the function of the motor, and the like are adversely affected.
For this reason, conventionally, insect traps are installed near the ceiling away from the cultivation target, and there is also a problem that it is difficult to perform maintenance such as disposal of the trapped insects, cleaning of the traps and repair of malfunctions.

In order to solve the above problems, the insect trap of the present invention is:
A plurality of light sources arranged around a virtual axis extending in the vertical direction and attracting insects;
A suction fan that is arranged to rotate about the virtual axis at intervals below the light sources, and sucks the insects;
A fan cover formed in a substantially cylindrical shape so as to cover the outer periphery of the suction fan;
Provided so as to cover the opening at the lower end of the fan cover, provided with an insect trapping net for capturing the insect,
The light source emits directional light and is configured such that the optical axis of the directional light faces the opening at the upper end of the fan cover or the periphery of the opening at the upper end.

  The light source is not particularly limited as long as it emits directional light. Examples of the light source include a light emitting LED and a light bulb with a lens. The plurality of light sources are not particularly limited, but may be configured by only one that emits light of one type of wavelength, or may be configured by a plurality of types of light that emit light of different types of wavelengths. Good. Although it does not specifically limit as a wavelength of light, It is preferable to set according to the peak of the compound eye spectral sensitivity of the insect to capture, Specifically, it sets within the range of 300-400 nm (More specifically, near 350 nm (Set to the ultraviolet region) or to set within a range of 500 to 600 nm (more specifically, set to around 550 nm (green region)).

  When configured so that the directional light of the light source is directed toward the periphery of the opening, the reflected light due to the projection of the directional light to the periphery of the opening is not directed toward the outer peripheral side of the insect trap. Although not particularly limited, an example in which the light source is disposed so that the optical axis of the directional light faces vertically downward and the periphery of the opening is formed horizontally is illustrated.

According to this configuration, the optical axis of the directional light emitted from the light source is configured to face the opening at the upper end of the fan cover or the periphery of the opening at the upper end. An effect is obtained.
(1) The light radiated around the insect trap can be greatly reduced as compared with the conventional case. Therefore, for example, in house cultivation where it is necessary to control the amount of light to the cultivation target, the influence on the surroundings by the light of the light source can be greatly reduced than before, and closer to the cultivation target than before It can be installed, and it is easy to perform maintenance such as disposal of captured insects, cleaning of insect traps and repair of malfunctions.
(2) Attracting insects in the opening of the fan cover or in the periphery of the opening by reflected light generated when the directional light is projected onto the suction fan in the fan cover or the periphery of the opening of the upper end. can do. Therefore, an insect can be efficiently sucked by the suction fan and captured by the insect trapping net.

  The said light source and the said suction fan illustrate the aspect comprised so that it might have waterproofness or drip-proof property.

  According to this structure, it becomes possible to use even in an environment where water supply to the cultivation target falls or in a high humidity environment, and the insect trap can be installed in the vicinity of the cultivation target.

  The said suction fan illustrates the aspect currently formed so that the rotation maximum diameter may become inside the opening of the said upper end part by planar view.

  According to this configuration, the airflow that passes through the opening at the upper end and enters the fan cover can be directed straight to the suction fan. Further, an air flow also occurs outside the maximum rotation diameter of the suction fan, and the air flow outside the air flows in a generally downward direction, so that the sucked insect is difficult to collide with the inner surface of the fan cover. This makes it difficult for the carcasses to adhere and accumulate. Further, even when a mesh-shaped or slit-shaped protective cover is provided at the opening at the upper end, insects are not easily caught on the protective cover, and insect clogging can be prevented. In particular, when an insect trap is installed in the vicinity of the cultivation target, insects tend to adhere to the inner surface of the fan cover, the protective cover, etc. due to the influence of moisture supplied to the cultivation target. It can be mitigated.

  If the relationship between the maximum diameter of rotation and the opening at the upper end is reversed, the airflow that passes through the opening at the upper end and enters the fan cover is once at the opening at the upper end. Because it is narrowed, the airflow becomes a drum shape. When this happens, the airflow becomes turbulent and energy loss increases, and the airflow that enters the fan cover is strengthened to spread by receiving force in the direction of the rotation of the suction fan, and insects riding on this airflow Is blown toward the inner surface of the fan cover, and it becomes easy to stick to the inner surface. Further, when the airflow is narrowed when passing through the opening at the upper end, the speed is temporarily increased. As a result, when a mesh-like or slit-like protective cover is provided in the opening, Insects can be caught easily, causing insect clogging.

  The fan cover exemplifies an aspect in which the opening at the upper end is formed so as to be inside the opening at the lower end in plan view.

  According to this configuration, airflow can be efficiently discharged from the opening at the lower end of the fan cover. Further, even when a mesh-shaped or slit-shaped protective cover is provided at the opening at the lower end, it is difficult for insects to get caught in the protective cover, and insect clogging can be prevented. In particular, when an insect trap is installed in the vicinity of a cultivation target, moisture adheres to the protective cover due to the influence of moisture supplied to the cultivation target, and insects are easily caught on the protective cover. According to, it can be reduced.

  If the size relationship between the opening at the upper end and the opening at the lower end is reversed, the airflow when passing through the opening at the lower end becomes a drum shape, which causes the energy loss of the airflow. Become. In addition, when a mesh-like or slit-like protective cover is provided at the opening at the lower end, insects are easily caught on the protective cover, which may cause insect clogging.

  The said fan cover illustrates the aspect provided with the protective cover which prevents a user's finger | toe from entering into the opening of the said upper end part, and / or the opening of the said lower end part.

  Although it does not specifically limit as said protective cover, The aspect currently formed in mesh shape and the aspect currently formed in slit shape are illustrated.

  According to this configuration, since the user's finger does not enter the fan cover, maintenance such as replacement of the insect trapping net and cleaning of the surface can be performed even when the suction fan is in operation. Therefore, even if an insect trap is installed in the vicinity of the cultivation target and the maintenance is frequently performed, the operation rate of the insect trap does not decrease, and the user can work with peace of mind.

  According to the insect trap which concerns on this invention, there exists the outstanding effect that it can install in the vicinity of cultivation object rather than before.

According to the insect trap 1 of the present example configured as described above, the optical axis L of the directional light emitted from the light source 2 is configured to face the opening peripheral portion 7 a at the upper end portion of the fan cover 7. Therefore, the following effects can be obtained.
(1) The light radiated around the insect trap 1 can be greatly reduced as compared with the conventional case. Therefore, for example, in house cultivation where it is necessary to control the amount of light, the influence of the light of the light source 2 on the surroundings can be greatly reduced compared to the conventional case, and it can be installed near the cultivation target than before. It is easy to perform maintenance such as disposal of captured insects, cleaning of insect traps and repair of malfunctions.
(2) Insects can be attracted to the vicinity of the opening 12 of the fan cover 7 by the reflected light by projecting the directional light onto the opening peripheral portion 7 a at the upper end of the fan cover 7. Therefore, an insect can be efficiently sucked by the suction fan 3 and captured by the insect trapping net 4.

  Moreover, since the light source 2 and the suction fan 3 are configured to have waterproof properties, the light source 2 and the suction fan 3 can be used in an environment where water is supplied to the cultivation target or in a high humidity environment. Can be installed.

  Further, since the suction fan 3 is formed so that the maximum rotation diameter D is inside the upper end opening 12 in plan view, it passes through the upper end opening 12 and enters the fan cover 7. The coming air stream can be directed straight to the suction fan 3. Further, an air flow also occurs outside the rotation maximum diameter D of the suction fan 3, and this outer air flow generally flows downward, so that the sucked insects do not easily hit the inner surface of the fan cover 7. Insect carcasses are less likely to adhere and accumulate. In addition, even when the protective cover 14 is provided in the opening 12 at the upper end, it is difficult for insects to get caught in the protective cover 14, and insect clogging can be prevented. In particular, when the insect trap 1 is installed in the vicinity of the cultivation target, insects tend to adhere to the inner surface of the fan cover 7, the protective cover 14, etc. due to the influence of moisture supplied to the cultivation target. According to that, it can be reduced.

  If the relationship between the maximum diameter D of rotation and the size of the opening 12 at the upper end is reversed, the airflow that passes through the opening 12 at the upper end and enters the fan cover 7 flows through the opening 12 at the upper end. Since it is once narrowed, the airflow becomes a drum shape. When this happens, the airflow becomes turbulent and energy loss increases, and the airflow that enters the fan cover 7 is strengthened and diffused by receiving a force in the direction of the outside of the rotation of the suction fan 3. Is blown toward the inner surface of the fan cover 7, and it becomes easy to stick to the inner surface. Further, when the air flow is narrowed when passing through the opening 12 at the upper end portion, the speed is temporarily increased. Thus, when the protective cover 14 is provided in the opening 12, insects are generated in the protective cover 14. It becomes easy to get caught and causes bug clogging.

  Further, since the fan cover 7 is formed such that the opening 12 at the upper end portion is located inside the opening 13 at the lower end portion in plan view, the air current is efficiently discharged from the opening 13 at the lower end portion of the fan cover 7. be able to. In addition, even when the protective cover 15 is provided in the opening 13 at the lower end, it is difficult for insects to get caught in the protective cover 15, and insect clogging can be prevented. In particular, when the insect trap 1 is installed in the vicinity of the cultivation target, moisture adheres to the protective cover 15 and the like due to the influence of moisture supplied to the cultivation target, and the insects are easily caught. It can be mitigated.

  If the size relationship between the opening 12 at the upper end and the opening 13 at the lower end is reversed, the airflow when passing through the opening 13 at the lower end becomes a drum shape. Cause. Further, when a protective cover 15 is provided in the opening 13 at the lower end, insects are easily caught on the protective cover 15, which causes bug clogging.

  Further, since the fan cover 7 includes protective covers 14 and 15 that prevent the user's fingers from entering the opening 12 at the upper end and the opening 13 at the lower end, the suction fan 3 remains in an activated state. Maintenance such as replacement and cleaning of the insect trap 4 can be performed. Therefore, even if the insect trap 1 is installed in the vicinity of the cultivation target and the maintenance is frequently performed, the operation rate of the insect trap 1 does not decrease, and the user can work with peace of mind.
