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, a pest trap that attracts pests to a light source and sucks and captures them by a suction means such as a fan has been proposed in, for example, Patent Document 1 and Patent Document 2.
The illumination device with an insect capturing function described in Patent Document 1 captures insects by sucking insects gathered in a light source such as an outside light, an entrance light, and a garden light installed outside the building into a collection bag with a rotating fan. In this way, it has the effect of being able to capture pests that gather in the light without impairing the function as an outdoor lighting fixture.

In addition, the suction type insect trap described in Patent Document 2 is configured such that the insect pest attracted by the attracting lamp is sucked by the suction device and captured in the insect catching net set in the wire net for catching. Therefore, the air discharged from the suction device is blown by a compressor and the air is circulated and used forcibly leading to the insect trapping net.

However, the lighting device with an insect trapping function described in Patent Document 1 and the suction-type insect trap described in Patent Document 2 have the following problems.
That is, in the lighting apparatus with an insect capturing function described in Patent Document 1, when the insects sucked into the collecting bag by the rotating fan are collected in the collecting bag to some extent, the rotating bag is stopped and then the collecting bag is removed from the casing. Although disposal such as disposal is performed, the air that has passed through the collection bag in which the pests are captured is discharged from the casing through the exhaust port.
For this reason, in the case of a luminaire installed outdoors as in Patent Document 1, there is little problem even if the air that has passed through the collection bag is discharged out of the casing from the exhaust port, but the capture of the pest is captured. The air that has passed through the collection bag contains mites and other bacteria that are parasitic on pests, and if pests such as moths are contained, scales that fall off may be mixed in the air. However, it cannot be used in facilities that handle foods, or it is avoided by users with allergies.

On the other hand, in the suction type insect trap described in Patent Document 2, since the air discharged from the suction device is further blown by the compressor and forcedly circulated to the insect trapping net, the air passing through the trapping net is Since it is not discharged out of the case, the problem as in the above cited reference 1 does not occur. However, the complicated structure in which the compressor is provided separately from the suction device increases the cost, and the suction device and the compressor each have a power source. Therefore, there is also a problem that it is uneconomical because the electricity bill increases when it is operated for a long time.
The present invention has been made to remedy such problems, and aims to provide a pest trap with a simple configuration at low cost, which can capture pests efficiently and consumes less power during operation. .

  The pest trap of the present invention is provided on a case provided with a light source for attracting pests in the opening and in the vicinity thereof, an upper passage provided above the inside of the case, and both sides inside the case. A side passage, a hopper installed below the light source, a cylindrical case connected at one end to the bottom of the hopper, and a pest installed at one end of the cylindrical case and attracted to the light source, A suction means for sucking into the cylindrical case together with air sucked from the opening, and a shutter plate that is opened by the wind pressure of the air sucked by the suction means and closed when the suction means is stopped are provided in the cylindrical case. The shutter means, and the other end side of the cylindrical case detachably attached, and a breathing bag that captures pests from the air discharged from the suction means, and the air that has passed through the insect bag, Depending on the blowing power of the suction means Those constructed from an air circulation path for circulating the periphery of the light source through the part passage and an upper passage.

With the above configuration, since the pests sucked into the casing 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 captured efficiently. Even if the air that passed through the collection bag contains mites and other bacteria that are parasitic on the pest, or the scales that have fallen off from the pest, such as spiders, are mixed, it has passed through the bag. Since air is not discharged outside the housing, it can be used mainly in facilities that handle foods, and even users with allergies such as allergies can use it with peace of mind.
In addition, air that has passed through the insect trapping bag is divided into two side passages provided on both sides of the inside of the housing and circulated to the top of the housing. Can be efficiently circulated, and this enables continuous operation of the pest trap with less power consumption. In addition, the running cost can be reduced, and the configuration is simple, so it can be provided at low cost.
Further, when disposing of the captured pests, the suction means loses its suction power because the upper surface opening of the cylindrical case is closed by the shutter that has been opened so far by turning off the light suction means. However, it is possible to prevent the pests from escaping to the suction means side by the shutter, and this ensures that even if there are living pests captured in the insect trap bag, they will not escape from the trap bag. Can do.

The pest trap of the present invention has a lower guide surface that redirects the air that has passed through the insect trapping bag in an upward direction inside the housing, and a side passage that uses the inclined surface of the hopper for the air that has been redirected by the lower guide surface. An intermediate guide surface for guiding the air flow and an upper guide surface for changing the direction of the air flow passing through the side passage to the upper passage are provided in the air circulation path.

  With the above configuration, the air that has passed through the collection bag is circulated through the air circulation path while being accelerated by the intermediate guide surface, so that air can be circulated smoothly and pulsation does not occur in the air flow. In addition, the flow resistance can be reduced.

  The pest trap of the present invention has a first baffle plate that redirects the air flowing in from both ends of the upper passage to the light source side at a substantially middle portion of the upper passage, and both ends of the upper passage on both ends of the upper passage. A second baffle plate that changes the direction of the air flowing into the light source side is provided.

  With the above configuration, air flows from the upper passage almost uniformly to the periphery of the light source, and air flow unevenness does not occur in the vicinity of the light source. become able to.

The pest trap of the present invention is provided with openings on the front and rear surfaces of the casing, and one of the openings can be closed with a detachable lid depending on where the casing is attached.

  With the above configuration, when the housing is used by attaching it to a wall surface or the like, a part of the wall surface is not exposed in the housing from the opening, so that the wall surface is soiled by insects or dust that are inhaled with air. In addition, since the pest can be inhaled together with the outside air intensively from the other opening, even if the opening is only on one side, the effect of capturing the pest is not lowered.

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, air that has passed through the insect trapping bag is divided into two side passages provided on both sides of the inside of the housing and circulated to the top of the housing. This makes it possible to efficiently circulate the pests, thereby enabling continuous operation of the pest traps with less power consumption, thereby reducing the running cost.

Embodiments of the present invention will be described in detail with reference to the drawings.
1 is a front perspective view of a pest trap, FIG. 2 is a cutaway perspective view of the same part, FIG. 3 is a cross-sectional view taken along line AA in FIG. 2, and FIGS. It is explanatory drawing.
The pest trap shown in FIG. 1 has a rectangular body 1 that is long in the vertical direction and flat in the front and rear, and pests are placed on the front plate 1a and the rear plate 1b of the housing 1 together with the outside air. The rectangular openings 1c and 1d for sucking into the housing 1 are opened. When the pest trap is attached to a wall surface or the like, it is prepared in advance in the opening 1d opened in the rear plate 1b. By attaching the lid 15, the opening 1 d can be closed.
The corners on the upper side of the housing 1a are inclined obliquely, the inner surfaces of these inclined surfaces serve as the upper guide surface 1e, and the light source having a U-shaped cross section at the inner upper portion of the housing 1a. The attachment member 2 is installed almost horizontally with the opening surface facing downward.

On the upper surface of the light source mounting member 2, socket mounting portions 2 a are formed at a plurality of locations, for example, three locations, spaced apart in the longitudinal direction, and the sockets 3 are respectively mounted on the lower surfaces of these socket mounting portions 2 a. An air inlet 2b is opened between the socket mounting portions 2a, and a light source 4 is detachably attached to each socket 3.
An upper passage 1g is formed in the horizontal direction between the upper surface of the light source mounting member 2 and the upper surface plate 1f of the housing 1a, and the air flow direction-converted by the upper guide surface 1e is the upper passage 1g from both ends. It is designed to flow in.
Near the middle of the upper passage 1g, a first baffle plate 1h for guiding the air flowing into the upper passage 1g downward from the air inlet 2b to the light source mounting member 2 is provided in the vertical direction. Secondly, air that has flowed in from both sides of the light source mounting member 2 flows into the lower side of the light source mounting member 2 through the gap 1j between the front and rear face plates 1b and 1c and the light source mounting member 2 at both ends of the mounting member 2. A baffle plate 1i is provided in the vertical direction.

A vertical partition plate 1m is provided in the upper part of the housing 1a so as to be parallel to the side plates 1k, and a side passage 1n is formed between the vertical partition plate 1m and the side plates 1k of the housing 1. The both ends of the light source mounting member 2 are fixed between the upper ends of the vertical partition plates 1m.
The light source 4 attached to the socket 3 bends a plurality of fluorescent tubes 4b that emit attraction light having a peak of the light wavelength component at a wavelength preferred by a pest, for example, 300 to 400 nm, and is formed in a U-shape. In order to increase the effect of attracting pests, a special lamp having a fluorescent tube 4b portion longer than a normal fluorescent lamp is used to open the front and rear surfaces of the housing 1. It is installed in the vertical direction at a position that can be seen from the openings 1c and 1d.

  Further, since the light source 4 is turned on for a long time, when the attracting effect is reduced or the life as the light source is reached, it can be easily replaced from the openings 1c and 1d. In order to prevent touching 4, damaging the light source 4, or entry of foreign matter into the housing 1, a grid 5 made of a linear material is detachably attached.

On the other hand, a hopper 6 is formed in almost the middle part of the housing 1 so as to cover the lower part of the light source 2.
As shown in FIG. 5, the hopper 6 is composed of an inclined surface 6a which is inclined on both sides of the housing 1 and inclined toward the center side, and a flat surface 6b formed at the center portion, and the upper portion of the inclined surface 6a is a vertical partition. It is connected to the lower end of the plate 1m, and the lower surface of the inclined surface 6a serves as an intermediate guide surface 1p for guiding the air that has passed through the insect trap bag 11 described later to the lower end side of the side passage 1n.
In the center of the flat surface 6 b of the hopper 6, a suction port 6 c made of a circular hole substantially equal to the inner diameter of the casing 7 a of the suction means 7 is opened, and a pair of rectifiers is provided above each inclined surface 6 a of the hopper 6. The plate 6d is provided in a substantially inverted C shape.

As shown in FIG. 5, the rectifying plate 6d has an inclination angle larger than that of the inclined surface 6a, the interval between the high position side of the inclined surface 6a and the upper end side of the rectifying plate 6d is wide, and the low position of the inclined surface 6a. Side, that is, the distance between the suction means 7 side and the lower end side of the rectifying plate 6d is set to be narrow, whereby the suction means 7 starts suction and the openings 1c and 1d of the housing 1 are opened. The flow of the sucked air is rectified so that the air around the light source 4 can be sucked almost uniformly.
The suction means 7 is composed of an electric fan, and has a cylindrical casing 7a as shown in FIGS. 2 and 3. The upper portion of the casing 7a is made of a screw or the like on the lower surface of the flat surface 6b of the hopper 6. It is fixed by a fixing tool 8.
An electric motor 7b is installed at the center of the casing 7a, and a fan 7c rotated by the electric motor 7b is provided between the inner periphery of the casing 7a and the outer peripheral surface of the electric motor 7b.

The shutter means 10 is connected to the lower end side of the casing 4a.
The shutter means 10 includes a cylindrical case 10 a and a shutter plate 10 b provided in the cylindrical case 10 a, and the upper end portion of the cylindrical case 10 a is connected to the lower surface of the casing 7 a of the suction means 7.
As shown in FIG. 3, the shutter plate 10b of the shutter means 10 is made of a disc having a diameter slightly smaller than the inner diameter of the cylindrical case 10a, and is formed in a thin plate shape by a light material such as plastic, and is formed from the center. The rotating shaft 10c is fixed in the surface direction at an eccentric position.
Both ends of the rotating shaft 10c are supported by the cylindrical case 10a so as to be horizontal, and a shutter plate 10b is rotatable around the rotating shaft 10c. A shutter plate is provided at both ends of the rotating shaft 10c. A spherical spacer (not shown) that forms a minute gap therebetween is fitted so that the outer peripheral edge of 10b does not contact the inner peripheral surface of the cylindrical case 10a.

The shutter plate 10b is provided with a balancer 10e on the eccentric side.
The balancer 10e returns the shutter plate 10b whose eccentric position is supported by the rotating shaft 10c to the horizontal position. The shutter plate 10b is automatically operated when the suction means 7 is stopped and the inside of the cylindrical case 10a becomes no wind. Thus, a stopper 10f is provided on the inner peripheral surface of the cylindrical case 10a so as to stop the shutter plate 10b at the horizontal position.

The cylindrical case 10a of the shutter means 10 is provided with a locking portion 10g projecting on the outer periphery of the lower portion, and the opening 11a of the insect bag 11 is locked to the locking portion 10g.
As shown in FIG. 2, the locking portion 10 g is formed of a protrusion protruding from the outer peripheral surface of the cylindrical case 10 a or a not-shown concave groove, etc., and a rubber band inserted in advance into the opening 11 a of the insect bag 11. The opening 11a is locked by the locking means 12 such as the above, so that the insect bag 11 does not fall off even if the suction means 7 receives wind pressure in the insect bag 11.
The insect pouch 11 is formed into a bag shape from a breathable material such as a fine mesh or nonwoven fabric that prevents small pests from passing through, and can be disposed of together with the captured pests.
The insect trap 11 has an opening 11a attached to the lower portion of the cylindrical case 10a so that the bottom does not contact the bottom plate 1q of the housing 1a, and both ends of the bottom plate 1q are inclined so that the ends are raised. These inclined surfaces serve as a lower guide surface 1r for guiding the air that has passed through the insect trap bag 11 to the lower end side of the side passage 1n.

The front plate 1b of the housing 1a has an insect trap exchange port 1x opened below the opening 1d. The insect trap bag exchange port 1x is provided with a door 13 that opens and closes when the insect trap bag 11 is attached and detached. ing.
One end of the door 13 is pivotally attached to the front surface of the housing 1a by a hinge 13a. By pulling a handle 13b provided on the other end of the door 13 toward the front, the door 13 can be opened and closed around the hinge 13a. A catch 14 that locks the door 13 in the closed position is provided on the open side of the door 13 and the inside of the housing 1a.

Next, the operation of the pest trap constructed as described above will be explained. As a place for installing the pest trap, a pest is mixed in food or products such as indoors, food processing plants, factories, restaurants, convenience stores, etc. However, there are no particular restrictions on the installation location, and it may of course be installed outdoors or in a facility such as a plastic house.
Further, when installing the pest catcher indoors, the housing 1a is arranged so that the light source 2 provided on the upper portion of the housing 1 is located near the ceiling so that the pests gathering on the lighting device installed on the ceiling can be efficiently captured. Is attached to the wall surface with a fixing tool (not shown), or a strong string-like object (not shown) is inserted into the suspension hole 1y provided in the upper portion of the housing 1, The casing 1 is suspended from the ceiling or the like by a string-like object.
When the housing 1 is attached to the wall surface, the opening 1d of the rear plate 1b is not necessary, so the opening 1d is closed by the lid 15.

  When the attachment of the housing 1 is completed, the door 13 provided on the front surface of the housing 1 is opened, and the opening 11a of the insect trap bag 11 prepared in advance is fitted to the outer periphery on the lower end side of the cylindrical case 10a. Even if the wind pressure acts downward from the inside of the insect trapping bag 11 by locking the portion 11a to the locking protrusion 10f protruding from the outer peripheral surface of the cylindrical case 10a by the locking means 12 such as a rubber band, the insect trapping The bag 10 is prevented from slipping down.

When the insect trap bag 11 is attached to the cylindrical case 10a and the door 13 is closed, a power switch (none of which is shown) provided in the middle of the housing 1 or the power cord is turned on.
As a result, the light source 4 is turned on, and at the same time, the fan 7c is rotated by the electric motor 7b of the suction means 7 to start blowing air.
When the air blowing by the suction means 7 is started, the air around the light source 4 is sucked into the cylindrical case 10a, so that the outside air near the ceiling is sucked into the housing 1 through the openings 1c and 1d.
The air sucked into the housing 1 from the openings 1c and 1d is accelerated by the rectifying action of the rectifying plate 6d provided in the hopper 6 and sucked into the suction means 7, so that the air around the light source 4 is It becomes possible to suck almost uniformly.
Further, since the light source 4 uses a special light bulb such as a fluorescent lamp that generates an attracting light having a wavelength preferred by a pest, a pest that has been attracted by a lighting fixture installed indoors and enters the indoor space is directed to the light source 4. When it is attracted and reaches the vicinity of the light source 4, it is sucked into the housing 1 together with the air sucked from the openings 1c and 1d.

On the other hand, when the shutter means 10 installed below the suction means 7 receives the wind pressure of the air blown by the suction means 7 on the shutter plate 10b that has been closed by the action of the balancer 10e, the shutter plate 10b rotates. Since it is opened by rotating about 90 degrees around the shaft 10c, the pests sucked together with the air by the suction means 7 are discharged into the insect trap bag 11 through the cylindrical case 10a.
Since the insect trapping bag 11 is formed of a material having air permeability, only the pests that have flown in with the air are captured by the insect trapping bag 11, and the air that has passed through the insect trapping bag 11 is provided at the lower ends of the bottom plate 1 q. Dividing into two paths by the inclination of the guide surface 1r, the direction of the casing 1 is changed upward as indicated by an arrow B in FIGS.
Thereafter, since the cross-sectional area of the air circulation path is gradually reduced by the intermediate guide surface 1p formed by the inclined surface 6a of the hopper 6, the air flow is lowered into the side passage 1n as shown by the arrow C in FIG. Inflow from.

The air that has flowed into the side passage 1n from below reaches the upper guide surface 1e while further increasing the flow velocity, and the direction is changed into the upper passage 1g from both ends of the upper passage 1g by the upper guide surface 1e.
Most of the air that flows into the upper passage 1g reaches the first baffle plate 1g provided in the middle of the upper passage 1g, and is redirected downward as indicated by an arrow D in FIG. 2 flows into the periphery of the light source 4 from the air inlet 2a opened on the upper surface of the light source 2, but part of the direction is changed in the direction of arrow E by the second baffle plates 1i provided on both ends of the light source mounting member 2. Then, the air flows into the periphery of the light source 4 from the gap 1j between the front and rear surface plates 1b and 1c and both side surfaces of the light source mounting member 2.

As a result, the air accelerated by the intermediate guide surface 1p is circulated through the air circulation path and pulsation does not occur in the air. Therefore, the air can be circulated smoothly, and the light source 4 can be uniformly distributed from the upper passage 1g. Since air does not flow into the periphery and air flow unevenness does not occur around the light source 4, the air is sucked into the suction means 7 again through the hopper 6 without interfering with the outside air sucked from the openings 1 c and 1 d. Is done.
During operation of the suction means 7, air circulation paths in the directions of arrow B, arrow C, arrow D, and arrow E are always formed, and the air that has passed through the insect trapping bag 11 is provided on both sides inside the housing 1. Since the air is diverted to the two side passages 1n and is circulated to the upper part of the housing 1, the air blowing means 7 having a small air blowing capacity can efficiently circulate the air and capture pests with less power consumption. As a result, the running cost can be reduced.

On the other hand, if pests accumulate to some extent in the capture bag 1 while operating for a long time, the pests caught in the capture bag 11 are discarded together with the capture bag 11. When the suction means 7 is turned off, the air blowing by the suction means 7 is stopped, and the shutter plate 10b, 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 10e, so that the cylindrical case 10a The upper surface opening is closed by the shutter plate 10b.
As a result, even if some of the pests captured in the insect trap bag 11 are alive, the shutter plate 10b prevents the insect pests from escaping to the suction means 7 side that has stopped suctioning by being turned off. It is possible to reliably prevent the living pests from escaping from the insect trapping bag 11.

When the light source 4 is turned off and the suction means 7 is completely stopped, the door 15 on the front surface of the housing 1 is opened, and the insect trapping bag 11 is removed from the lower portion of the cylindrical case 10a while the opening 11a of the insect trapping bag 11 is manually squeezed. By disposing and discarding the catching bag 11 with the opening 11a of the catching bag 11 closed, the entire catching bag 11 can be discarded without escaping the captured pests.
When the new insect trap bag 11 is attached to the lower part of the cylindrical case 10a, the insect pest can be continuously captured by closing the door 15 and starting the operation of the insect trap again.
