Description

  The present invention relates to a pest trap that attracts pests to a light source and efficiently captures them by suction means.

Pests such as moths, mosquitoes, moths and feather ants are disliked as unpleasant pests. If these pests enter into facilities such as food processing plants, restaurants, factories, mass retailers, convenience stores, etc. In the case of food processing plants, etc., even if pests are mixed in one product, there is a situation where all the products produced in the same lot are collected. There is a problem that arises and causes a large economic loss.
For this reason, these facilities take measures such as sealing the building to prevent the entry of pests from the outside to the inside, but in the case of pests that have the habit of gathering in the light, the building should be sealed. In some cases, the light is attracted by light from a slight gap and enters the house, and when a person enters or exits the building, it often adheres to the person and enters the room.
Insect pests that have entered the house are exterminated using insecticides, etc., but in food processing facilities, restaurants, convenience stores, etc., mainly food handling facilities use insecticides. There is a problem that cannot be removed.

On the other hand, for example, Patent Document 1 proposes an insect trap that attracts harmful insects to an attracting light, sucks them with a fan, and captures them in a trap bag.
The insect trap described in Patent Document 1 is configured to suck a pest attracted by an attracting light by a large fan that is intermittently driven and capture it in an insect trap bag.
In addition, a funnel-shaped closing means that expands by wind pressure with the rotation of the fan is provided at the rear of the insect trapping bag, and the insects sucked by the fan pass through the expanded blocking means and enter the insect trapping bag. When the fan stops, the closing means is automatically closed so that the pests captured in the insect trap bag cannot escape from the trap bag.
Furthermore, in the insect trap configured as described above, the fan stop pests gather without discomfort by intermittently rotating the large fan, so that the flying pests can be efficiently captured and the pheromone emitted from the captured pests is large. Since it can be scattered to the surroundings by a fan, there is also an effect that pests can be attracted efficiently and widely.
Japanese Utility Model Publication No. 6-33472

However, in the insect trap described in Patent Document 1, since the large fan is used to suck the pests, the entire apparatus becomes large.
For this reason, there is no particular problem when using it in orchards, cowsheds, poultry houses, etc., but it is not practical when used in ordinary households, restaurants, convenience stores, etc., because it requires a large place to install In addition, there is a problem that the price of the insect trap itself increases.
Also, because a large amount of air blown by a large fan and passed through the insect trap bag is scattered to the surroundings, it is generated from scales and insects that have fallen off mites, germs, moths, etc. parasitic on the insects that have been captured. Pheromones etc. are diffused over a wide area together with air and cannot be used mainly in facilities that handle foods, or are avoided by users with allergies and other diseases.
Furthermore, the closing means provided at the rear part of the insect trapping bag is formed of a breathable permeable member such as a mesh or a net, so that when the closing means is pushed open by wind pressure, small pests in the air adhere to and accumulate on the closing means. This may hinder the automatic closing of the blocking means, and it will not be possible to reliably prevent the pests captured in the trapping bag from escaping, and it will be necessary to replace the blocking means together when replacing the trapping bag, which increases the cost. There are problems such as.
The present invention has been made to remedy such problems, and can be easily installed in ordinary households, restaurants, convenience stores, etc., and provides a small pest trap with a simple structure at a low cost that can capture pests efficiently. It is intended to do.

  The pest trap of the present invention includes an upper case having a light source for attracting pests on the lower surface, a lower case provided below the upper case, a pest intrusion opening between the upper and lower cases, A suction means comprising an electric fan that is installed in the case and sucks the pests attracted by the light source together with air, and a cylindrical case having an upper end connected to the lower portion of the suction means, and is sucked by the suction means The shutter plate is opened by the air pressure of the air and closed when the suction means is stopped, and the shutter means provided in the cylindrical case is provided so as to surround the light source at the pest entry port, and from the pest entry port. Guide means for guiding the sucked air in the direction of the suction means, and a detachably attached to the lower part of the cylindrical case, and a trap for capturing pests from the air discharged from the suction means. Those constructed from the trapping bag having sex.

With the above configuration, since the pests sucked together with the air by the suction means are discharged into the insect trap bag through the cylindrical case and captured, the pests attracted by the light source can be efficiently captured. Even if the air that has passed through the collection bag contains mites or other bacteria that are parasitic on the pest, or the scales that have been peeled off from the pest, such as spiders, are mixed, the air that has passed through the collection bag is widespread. Therefore, even users with allergies such as allergies can use it with peace of mind.
When the captured pests are to be disposed of, even if the suction means loses suction power by turning off the suction means, the upper surface opening of the cylindrical case is closed by the shutter plate that has been open until now. Pests can be prevented from escaping to the suction means side by the shutter plate, so that even if there are pests that have survived among the pests captured in the catching bag, they can be surely prevented from escaping from inside the catching bag. In addition, since no harmful insects adhere to and accumulate on the shutter plate, it is very economical as compared with the conventional one that replaces the insect trapping bag and the closing means at the same time.
In addition, since the entire pest trap can be manufactured in a small size, it can be easily installed in general homes, restaurants, convenience stores, etc., where installation space is limited, and it is inexpensive because it has a simple configuration. You can also.

  In the pest trap of the present invention, the shutter plate is formed of a lightweight thin plate, and the eccentric position of the shutter plate is fixed to the rotation shaft, and both end sides of the rotation shaft are arranged so that the shutter plate rotates about the rotation shaft. A balancer that supports the cylindrical case and that returns the shutter plate in the horizontal direction is provided on the eccentric side of the shutter plate.

  With this configuration, it is not necessary to provide an opening / closing means for returning the shutter plate to the closed position when the operation is stopped, so that the shutter means can be obtained at a low cost.

  In the pest trap of the present invention, the guide means is formed of a plurality of annular guide plates having tapered surfaces that gradually incline toward the center side, and a plurality of struts supporting the guide plates, and each guide plate is designated as a finger. Is fixed to the support column at intervals where it is difficult to enter.

  With the above configuration, since the outside air around the pest entry port can be efficiently guided to the suction means side by each guide plate, insect trapping efficiency is improved, and it is possible to prevent the finger from touching the light source and the electric fan in advance. Therefore, safety is high.

  The pest trap of the present invention is a lower case provided with a bellows-like cover that covers the periphery of the insect trapping bag.

  With the above-described configuration, unpleasant insects such as moths, mosquitoes, moths, feather ants and the like captured in the insect bag by the cover are difficult to see from the outside, so that discomfort can be reduced.

According to the pest trap of the present invention, even if the air that has passed through the collection bag contains mites or other bacteria that are parasitic on the pest, or scales that have been peeled off from pests such as moths are mixed, Since the air that has passed through the insect trapping bag is not discharged outside the housing, it can be used mainly in facilities that handle food, and it can be used with peace of mind even for users with allergies and other diseases. Can do.
In addition, since the entire pest trap can be manufactured in a small size, it can be easily installed in ordinary homes, restaurants, convenience stores, etc., where installation space is limited, and it is inexpensive because it has a simple configuration. You can also.

On the bottom surface of the bottom plate 2d of the lower case 2b, a socket 12a is fixed substantially at the center, and a light bulb type light source 12 is detachably attached to the socket 12a.
The light source 12 is a fluorescent lamp that emits an attracting light having a peak of a light wavelength component at a wavelength preferred by a pest, for example, 300 to 400 nm. When the light source 12 is cut off or the illuminance decreases with the lifetime, the upper case 2 is It can be easily replaced with a new light source 12 by being removed.
The lower case 3 is formed of a cylindrical body having an outer diameter substantially equal to the outer diameter of the upper case 2, and an annular support plate 3 a is provided inside slightly below the upper end.
The pest entry port 4 provided between the upper case 2 and the lower case 3 is for a pest attracted by the light source 12 to enter the main body 1. At the same time, a guide means 13 for preventing the hand etc. from directly touching the light source 12 is provided.

As shown in FIG. 2, the guide means 13 includes a plurality of columns 13b made of, for example, metal pipes, and a plurality of guide plates 13a fitted and inserted into these columns 13b.
The upper end portion of each column 13b is fixed to the bottom plate 2d by a nut 13c while passing through the bottom plate 2d of the lower case 2b, and the lower end of each column 13b is screwed to the column plate 3a of the lower case 3.
The columns 13b are arranged at substantially equal intervals in the circumferential direction of the main body 1, and a plurality of mounting holes 13d drilled in the guide plate 13a are inserted into the columns 13b.
As shown in FIG. 2, each guide plate 13a is formed of a tapered annular plate having a circular hole 13e opened in the center and inclined so as to be gradually lowered from the outer peripheral edge side to the circular hole 13e side. The guide plates 13a are fitted at intervals, and the intervals between the guide plates 13a are set such that a child's finger cannot enter and a relatively large pest such as a moth can enter.

The suction means 5 installed in the lower case 3 is provided with a fan 5c rotated by an electric motor 5b in a casing 5a, and the upper surface of the casing 5a is fixed to the lower surface of the support plate 3a of the lower case 3. The insect pests attracted by the light source 12 and entered from the insect entry port 4 are sucked into the cylindrical case 6a of the shutter means 6 provided below the suction means 5 by the fan 5c rotated by the electric motor 5b. It is like that.
The shutter means 6 includes a cylindrical case 6 a and a shutter plate 6 b provided in the cylindrical case 6 a, and the upper end portion of the cylindrical case 6 a is connected to the lower surface of the casing 5 a of the suction means 5.

As shown in FIG. 3, the shutter plate 6b of the shutter means 6 is made of a disc having a diameter slightly smaller than the inner diameter of the cylindrical case 6a, and is formed in a thin plate shape by a light material such as plastic, and from the center. The eccentric position is fixed to the rotating shaft 6c.
Both ends of the rotating shaft 6c are supported by the cylindrical case 6a so as to be horizontal, and a shutter plate 6b is rotatable about the rotating shaft 6c. A shutter plate is provided at both ends of the rotating shaft 6c. A spherical spacer 6d that forms a minute gap therebetween is fitted so that the outer peripheral edge of 6b does not contact the inner peripheral surface of the cylindrical case 6a.

The shutter plate 6b is provided with a balancer 6e on the eccentric side.
The balancer 6e returns the shutter plate 6b whose eccentric position is supported by the rotating shaft 6c to the horizontal position. The shutter plate 6b is automatically operated when the suction means 5 is stopped and the inside of the cylindrical case 6a becomes no wind. The stopper 6f protrudes on the inner peripheral surface of the cylindrical case 6a to stop the shutter plate 6b in contact with the shutter plate 6b at the horizontal position.
The cylindrical case 6a of the shutter means 6 is provided with a locking portion 6g projecting on the outer periphery of the lower portion, and the opening 15a of the insect repellent bag 15 is locked to the locking portion 6g.

As shown in FIG. 4, the locking portion 6 g is composed of a protrusion protruding from the outer peripheral surface of the cylindrical case 6 a, a not-shown concave groove, and the like, and a rubber band inserted in advance through the opening 15 a of the insect bag 15. The opening 15a is locked by the locking means 15b such as the above so that the insect bag 15 does not fall off even if the suction means 5 receives wind pressure in the insect bag 15.
The insect pouch 15 is formed into a bag shape from a breathable material such as a fine mesh or a non-woven fabric that does not allow small pests to pass through, and can be disposed of together with the captured pests.

On the other hand, a bellows-like cover 16 is attached to the lower part of the lower case 3.
This cover 16 covers the periphery of the pest bag 15 so that the pests captured in the pouch 15 cannot be seen from the outside. The cover 16 is formed of a soft resin so as to have the same diameter as the lower case 3 and extends. In this case, the length is set so that the lower part of the insect bag 15 cannot be seen.
Further, when replacing the insect bag 15, the insect bag 15 can be easily replaced by contracting as shown in FIG. 6.

Next, the action of the insect trap will be explained. The place where the insect trap is installed is a place where a person or a person who does not want to have insects mixed in foods and products such as indoors, food processing plants, restaurants, and convenience stores. Suitable for places where discomfort is a problem, and because the pest trap itself can be manufactured in a small size, it is particularly suitable for ordinary homes, restaurants and convenience stores with limited installation space. However, there are no restrictions on the installation location, and of course, it may be installed in facilities such as outdoors or a plastic house.
When the pest trap is installed indoors, the upper case 2 is provided so that the light source 12 provided at the top of the main body 1 is near the ceiling so that the pests gathering on the lighting fixtures installed on the ceiling can be efficiently captured. The string-like object 8 is bound to the hanging tool 9 and the main body 1 is suspended from the ceiling or the like.

When the attachment of the main body 1 is completed, the bellows-like cover 16 attached to the lower part of the lower case 3 is contracted to the position shown in FIG. 6, and the opening 15a of the insect trap 15 prepared in advance is placed on the lower end side of the cylindrical case 6a. By fitting the outer periphery of the opening 15a to the engaging portion 6g projecting from the outer peripheral surface of the cylindrical case 6a by the engaging means 15b such as a rubber ring, the wind pressure is applied from the suction means 5. Even if it acts downward from the inside of the insect trapping bag 15, the insect trapping bag 15 can be prevented from slipping down.
When the attachment of the insect trap 15 is completed, the cover 16 is extended to the original position, and then the power switch provided in the middle of the power cord 10 is turned on. Then, the light source 12 is turned on and simultaneously the electric motor 5b of the suction means 5 is turned on. Rotates, and blowing by the fan 5c is started.

When the fan 5c is rotated by the electric motor 5b, the air around the light source 12 is sucked into the lower case 3 by the suction means 5, so that the air near the ceiling is sucked from the pest entry port 4.
A plurality of guide plates 13a inclined downward are provided at the pest intrusion port 4 at substantially equal intervals in the vertical direction, and the air sucked into the pest intrusion port 4 flows downward by the guide action of these guide plates 13a. Therefore, even the suction means 5 having a small suction capacity can efficiently take in the outside air around the pest entry port 4, and the air sucked into the pest entry port 4 is increased by the rectifying action of the guide plate 13a. Since the air is sucked into the suction means 5, the air around the light source 12 can be sucked almost uniformly.

  In addition, since the light source 12 uses a light bulb such as a fluorescent lamp that generates an attracting light having a wavelength preferred by a pest, a pest that is attracted by a lighting fixture installed indoors and enters the indoor space also enters the light source 12. When it is attracted and reaches the vicinity of the light source 12, it is sucked into the suction means 5 together with the air sucked into the pest entry port 4.

  On the other hand, when the shutter means 6 installed below the suction means 5 receives the wind pressure (arrow C in FIG. 5) of the air blown by the fan 5c on the shutter plate 6b that has been closed by the action of the balancer 6e until now, Since it is opened by rotating about 90 degrees around the rotating shaft 6c, the pests sucked together with air by the suction means 5 are discharged into the insect trap bag 15 through the cylindrical case 6a. Since only insect pests are captured in the insect trap bag 15 formed of a net or nonwoven fabric, and the air passes through the trap bag 15 as shown by the arrow D in FIG. The pests attracted by the light source 12 can be efficiently captured in the insect trap bag 15.

If a certain amount of pests accumulates in the catching bag 15 during the long-time operation, the pests captured in the catching bag 15 are discarded together with the catching bag 15. When the suction means 5 is turned off, the air blowing by the suction means 5 is stopped, and the shutter plate 6b, which has been in the open position until now by the wind pressure, is rotated to the horizontal position by the action of the balancer 6e, and the upper surface of the cylindrical case 6a The opening is closed by the shutter plate 6b.
As a result, even if some of the pests captured in the insect trap bag 15 are alive, the shutter plate 6b prevents the insect pests from escaping to the suction means 5 side that has stopped sucking by being turned off. It is possible to reliably prevent the living pests from escaping from the insect trap bag 15.

When the light source 12 is turned off and the suction means 5 is completely stopped, the cover 16 is contracted to the position shown in FIG. 6 to expose the insect trapping bag 15, and the tube 15 is manually squeezed while the aperture 15a of the insect trapping bag 15 is squeezed. By removing the insect trapping bag 15 from the lower part of the shaped case 6a and discarding it with the locking means 15b closing the opening 15a of the insect trapping bag 15, the entire insect trapping bag 15 can be discarded without escaping the captured insect pest. it can.
When the new insect trap bag 15 is attached to the lower part of the cylindrical case 6a, the cover 16 is extended to the position shown in FIG. 1 and the insect trap is started again so that the insect trap can be continuously captured. become.

In the above embodiment, the cover 16 is formed in a bellows shape, but the same effect can be obtained by providing a cylindrical cover that can slide up and down along the outer peripheral surface of the lower case 3.
Further, although an example in which a power switch is provided in the middle of the power cord 10 has been described, it is needless to say that a power switch may be provided on a part of the main body 1, for example, the lower case 3.

It is a front view of the pest trap which becomes an embodiment of the present invention. It is sectional drawing which follows the AA line of FIG. It is a partially cutaway perspective view near the suction means of the pest trap according to the embodiment of the present invention. FIG. 3 is an enlarged view within a circle B in FIG. 2.
