Description

Insect trap

Technical Field

The utility model relates to an insect trap. In particular, the present invention relates to an insect trap which has an excellent insect-catching effect on small insects and is easy to post-treat after catching insects without using an ultraviolet lamp as an attracting means.

Background

Conventionally, in semiconductor factories, food processing factories, and the like, invasion of small insects such as flies, mosquitoes, moths, and the like has not been permitted in factories for product management, sanitation, and the like.

Therefore, it is necessary to clean the inside of the factory and use air showers at the entrances and exits, but even in this case, small insects adhere to the objects and human bodies and invade the inside of the factory.

In addition, the light in the convenience stores and homes causes a problem of attracting many small insects to invade the interior.

Therefore, various insect traps for small insects have been proposed for use not only in semiconductor factories or food processing factories, but also in small convenience stores and homes.

For example, there has been proposed an attracting type insect trap which can effectively cool an LED emitting ultraviolet rays when the LED is used as an attracting light source. More specifically, as shown in fig. 7, in the suction type insect trap 101, an opening is provided in the vicinity of the suction opening 102, and at least 1 opening is provided in other portions, and the fan blades 103 generate air flow, so that insects are sucked and trapped in the insect retention section 105.

The suction type insect trap 101 is characterized in that an LED type ultraviolet ray emitter 104 is provided in the vicinity of the suction opening 102, and the LED type ultraviolet ray emitter 104 is provided in the shape of a barrel having a space, and a heat generating part is brought into contact with or exposed from the space to cool the air.

Further, an insect trap has been proposed in which insects are attracted by an ultraviolet lamp as an attracting light source and the attracted insects are captured by using an insect-catching paper. More specifically, as shown in fig. 8, the insect trap 201 includes an attracting light source 202 composed of an ultraviolet lamp for attracting insects, an insect-catching paper 204 for catching small insects, and a housing 203 having openings at the front and rear and having an attracting light source and an insect-catching paper inside.

In the insect trap 201, an attracting light source 202 formed of an ultraviolet lamp is provided inside the housing 203, and the insect trap 201 is provided with an insect-catching paper 204 inclined toward the attracting light source 202 and reflects ultraviolet rays from the attracting light source 202.

However, the suction type insect trap described in patent document 1 uses an LED that emits ultraviolet rays as a trapping device, and has a problem of insufficient safety when the ultraviolet rays emitted from the trapping device are observed from a person outside the housing thereof.

Further, the suction type insect trap can capture only small insects into the insect retention part basically, and there are problems that the insecticidal property of the small insects is insufficient and the disposal is not easy.

That is, when collecting the small insects from the insect retention section of the suction type insect trap, it is difficult to capture the small insects in a living state, and it is difficult to handle the small insects, and there is a problem that the small insects escape to the outside again.

In addition, since the insect trap described in patent document 2 basically uses an ultraviolet lamp as an attracting light source, there is a problem that safety is insufficient when people outside the housing observe ultraviolet rays emitted from the ultraviolet lamp.

In addition, the use of the insect catching paper limits the amount of small insects to be caught, and there is a problem that the insect catching paper needs to be frequently replaced in a place where the insect catching paper is used.

Therefore, there are problems that the replacement of the insect-catching paper causes troublesome operations and increases costs, and at the same time, a disposal problem of simultaneous disposal of small insects including the insect-catching paper must be considered. Prior art documents.

Detailed Description

First embodiment

In the first embodiment, as shown in fig. 1, the insect trap 10 is characterized by including at least a suction part a, a charging part B, and a trap part C in this order inside the housing 12. The suction part a has a suction port 12B for sucking the small insects, the charging part B has a ground wire (GND)14a and a discharge wire 14B for charging the small insects by corona discharge, and the trap part C is configured by arranging a plurality of plates 16 with electrodes at a predetermined interval, so that a predetermined electric field is generated between the adjacent plates 16 with electrodes, and the small insects are trapped between the plates 16 with electrodes.

Hereinafter, the insect trap 10 according to the first embodiment of the present invention will be described in detail with reference to fig. 1 and the like as appropriate.

1. Basic structure

As shown in fig. 1 and 2, a basic structure of the insect trap 10 for trapping small insects by electrocution includes at least a suction portion a, a charging portion B, and a trapping portion C at predetermined positions inside a housing 12.

Therefore, the small insects which are forcibly sucked into the suction section a or sucked in accordance with the characteristics of the small insects are electrostatically charged in the charging section B, and further, after the small insects are electrically or physically captured by the capturing section C, the small insects can be simultaneously electrocuted or made into an electrocuted state.

The insect trap 10 shown in fig. 1 and 2 is preferably a so-called vertical insect trap 10 in which at least the suction part a, the charging part B, and the capturing part C are arranged substantially inside the casing 12 in this order from bottom to top, because the installation area thereof is required to be small and the suction ports 12B and 12' B of the suction part a and the bottom plate 12a can be designed as a square.

Fig. 1 is a view provided for explaining the main components of the insect trap of the present invention. Fig. 2 is a view provided for explaining a main component and an additional component of the insect trap of the present invention.

On the other hand, although not shown, at least the suction part, the charging part, and the capturing part may be arranged in a right-to-left direction or a left-to-right direction inside the housing of the insect trap.

In the case of such a horizontal insect trap, the trap is not easily turned upside down when it is placed on a bed or when an earthquake or vibration occurs.

Further, since the design is more easily made compact than the insect trap of the vertical row, the weight of the insect trap can be reduced, and the insect trap can be hung on a wall or hung near a window.

The small insects of the insects as the capture objects include: at least one of flies, mosquitoes, moths, butterflies, aphids, beetles, mantises, sand flies, chironomids and the like, wherein the flies and the mosquitoes are typical small insects.

The body length of the small insects which are the insects to be captured is usually preferably a value in the range of 1mm to 30mm, more preferably a value in the range of 2mm to 10mm, and still more preferably a value in the range of 3mm to 5 mm.

2. Basket body

The housing 12 of the insect trap 10 shown in fig. 1 and 2 includes at least a suction part a, a charging part B, and a trap part C at predetermined positions therein, and is a housing that mechanically and electrically protects these parts a to C.

Therefore, the housing 12 is preferably formed of at least one of a polypropylene resin, a polyester resin, a polyacrylic resin, a polyurethane resin, a polycarbonate resin, a polystyrene resin, a polyacetal resin, an ABS resin, a polyimide resin, a polyamide resin, a fluororesin, and a silicone resin as a main component.

In addition, the material constituting the housing 12 preferably contains at least one of the following fillers with respect to the main components, in consideration of the need to significantly improve mechanical strength, dimensional stability, and the like: glass fiber, carbon fiber, nanofiber, glass particle, carbon particle, inorganic particle, organic particle, etc., and the content is 0.1 to 30 wt% relative to the total amount.

The housing 12 may be formed into a predetermined shape such as a cube or a cylinder according to a known molding method such as an injection molding method, an extrusion molding method, a die stamping method, or a three-dimensional printing and cutting device, which is known and accepted.

3. Suction part

As shown in fig. 1 and 2, the small insects are guided to the introduction portion of the suction port 12b of the suction portion a from the outside.

Therefore, the suction unit a is characterized by having at least one suction port 12b, 12' b for sucking small insects.

When the small insects approach the suction ports 12b, 12 'b provided in the bottom plates 12a, 12' a below the suction portion a, they are sucked in accordance with the ventilation effect or the suction flow as the air flow, or the characteristic that the small insects like to enter the dark place.

Further, if the inside of the housing 12 is brought into a predetermined reduced pressure state by a predetermined suction device 20, the small insects can be sucked more efficiently in the suction portion a.

In addition, the rollers 12c and 12 ' c are provided on the bottom plates 12a and 12 ' a provided under the suction part a, so that the insect traps 10 and 10 ' can be easily moved to any position.

Further, by changing the height positions of the rollers 12c and 12 'c, the height positions of the suction ports 12b and 12' b can be easily changed, and further, small insects can be more effectively sucked according to the kind of small insects and the like.

4. Charged part

(1) Basic structure

As shown in fig. 1 and 2, the charging section B is a section for electrostatically charging the vermin by applying a voltage to generate a predetermined discharge current by corona discharge.

Therefore, as shown in fig. 1, the charging section B preferably includes, as a basic configuration, a ground line (metal plate electrode, GND)14a and a discharge line (metal wire) 14B to which a high voltage is applied and which generates a discharge current of 1uA to 20 mA.

(2) High voltage application condition 1

By electrically connecting a predetermined direct current power supply or an alternating current pulse power supply between the discharge line and the ground line (GND), it is generally necessary to apply a high voltage of preferably 500 to 10000V in order to generate a discharge current of 1uA to 20mA, for example.

In addition, as the high voltage applying condition, preferably by applying 2000 to 8000V high voltage to generate 3 μ A to 15mA discharge current, more preferably by applying 4000 to 7000V high voltage to generate 5 μ A to 10mA discharge current.

(3) High voltage application condition 2

The power supply electrically connected between the discharge line and the ground line (GND) is usually a dc power supply, but an ac pulse power supply may be electrically connected and used in combination with a dc power supply of a predetermined voltage.

(4) Polarity of discharge current

It is desirable that the high voltage is applied between the discharge line and the ground line (GND) to generate a discharge current of a predetermined polarity, thereby reliably electrostatically charging the small insects to a predetermined or higher charge regardless of the type of the small insects.

In other words, the polarity of the high voltage may be either positive or negative, but it is preferable to determine and apply the high voltage under the condition that the polarity of the electric field generated in the trap unit described later is opposite.

5. Capturing part

(1) Basic constitution

As shown in fig. 1 and 2, the capturing section C captures small insects electrostatically charged in the charging section B between a plurality of electrode-carrying flat plates 16 that generate a predetermined electric field, and thereby electrocutes or becomes a site in an electrocuted state.

Therefore, as a basic configuration of the capturing section C, a plurality of plates 16 with electrodes are arranged at predetermined intervals, and the adjacent plates 16 with electrodes are electrically insulated from each other, so that a predetermined electric field is generated, and the electrostatically charged vermin can be electrically attracted to die and physically captured.

(2) Polarity of electric field

When a high voltage on the positive electrode side is applied to the small insects in the charging section B, an electric field on the negative electrode side is generated in the capturing section C, and the small insects are captured between the plurality of electrode-carrying plates 16.

(3) Arrangement of electrode-carrying plate 1

As shown in fig. 3C and 4C, in the capturing part C, the interval (t1) between the adjacent flat plates 16, 16' is preferably set to a value within the range of 1 to 5 mm. The reason is that the intensity of the predetermined electric field generated between the adjacent flat plates can be easily adjusted to be within a predetermined range by limiting the interval (t1) between the flat plates with electrodes to a value within a predetermined range.

Further, by trapping the small insects in a state of being sandwiched between the adjacent flat plates, etc., the interval (t1) is limited to a value within a predetermined range, whereby it is possible to cope with various sizes of small insects.

Therefore, the interval (t1) between the adjacent flat plates is preferably set to a value within the range of 1.5 to 4.5mm, more preferably within the range of 2 to 4 mm.

As shown in fig. 5(a) to (C), the frame 16h of the capturing section C is a member capable of three-dimensionally arranging a plurality of electrode-carrying plates 16 at predetermined intervals.

The frame 16h includes predetermined circuit wiring (not shown), and a known electrically insulating material, such as a polypropylene resin, an epoxy resin, or a phenol resin, can be preferably used.

(4) Arrangement of electrode-carrying plate 2

The intervals between the adjacent electrode-carrying flat plates 16 are not necessarily equal as shown in fig. 5 a (t1), but as shown in fig. 5c, the intervals between the arranged plurality of electrode-carrying flat plates 16 are gradually narrowed from left to right or from right to left (t10 to t16), and may be conversely gradually widened.

This is because the electric field intensity can be controlled within a suitable voltage range and several values even in one trap section by arranging the plates 16 with electrodes at unequal intervals, and further, the electric field intensity can be adjusted within a suitable range according to the size of the small insects and the like.

The plurality of electrode-carrying flat plates 16 are not necessarily required to be parallel to each other at an angle in the vertical direction (orthogonal direction, θ 1) as shown in fig. 5 a, and are preferably arranged in parallel in an inclined state at a predetermined angle (θ 2) as shown in fig. 5 b.

The reason for this is that the electrode-carrying plates 16 are arranged in parallel in an inclined state, whereby the area of each of the electrode-carrying plates 16, 16c can be increased, and the electric field intensity can be adjusted within an appropriate range according to the size of the small insects, etc.

(5) Electric field intensity

The electric field strength generated in the trap section C of the insect trap 10 is preferably 1kV/mm or more.

The reason for this is that the small insects electrostatically charged can be reliably captured in the capturing section C by setting the electric field generated between the adjacent plates to a value in a desired range.

However, if the electric field intensity generated in the capturing section C is too large, power consumption may be excessive, or a power supply device (not shown) required to generate a predetermined electric field intensity may be large.

Therefore, the electric field intensity generated in the trap section C is preferably in the range of 1 to 2 kV/mm.

(6) Incombustible material

In the trap part C, the flat plate 16 with an electrode may be made of a material including a paper containing a nonflammable component, a nonwoven fabric containing a nonflammable material, a felt containing a nonflammable material, a resin containing a nonflammable material, or at least one of a paper, a nonflammable nonwoven fabric, a nonflammable felt, and a nonflammable resin.

the reason for this is that the incombustible flat plate material can be used as a trap part having excellent safety even when a predetermined voltage is continuously or intermittently applied and a predetermined electric field is formed for a long time, and the trap part can be formed into various desired shapes.

Therefore, the incombustible material is preferably impregnated or adhered with at least one of magnesium hydroxide, calcium hydroxide, a halide-based flame retardant, a phosphoric-acid-based flame retardant, a paper, a nonwoven fabric, a felt, and a resin, such as a phenol resin and a polyimide resin.

Further, V1 or more of UL94V standard or V0 is preferable as the standard for incombustibility of flat sheets.

As shown in fig. 3(a) and 4(a), the structure of the flat plates 16a and 16' a, which are main components of the capturing section, is also not limited.

Therefore, when the flat plate 16a, 16 'a is assumed to be substantially rectangular, the length (L1, L' 1) thereof is preferably within a range of 5 to 25cm, more preferably within a range of 8 to 20cm, and still more preferably within a range of 10 to 15 cm.

The width (L3, L '3) of the flat plates 16a, 16' a is preferably in the range of 4 to 15cm, more preferably in the range of 5 to 12cm, and still more preferably in the range of 6 to 10 cm.

As shown in fig. 6(a) to (e), the flat plate may have various shapes.

For example, the flat plate 16i shown in fig. 6(a) is a general resin plate, and is excellent in terms of weight reduction, electrical insulation, moldability, cost, and the like.

Therefore, it is preferably made of a heat-resistant resin such as polyimide, fluororesin, flame-retardant polyester, or the like.

The flat plate 16i shown in fig. 6(b) is a plate made of a flame retardant resin containing a predetermined amount of a flame retardant (e.g., 1 to 30% of the total amount of the flame retardant).

If the capturing section (C) is composed of a flame retardant resin containing the flame retardant, the safety of the capturing section (C) can be further improved.

As shown in fig. 6(c), the flat plate 16k is made of heat-resistant woven or nonwoven fabric such as polyimide, fluorinated resin, and flame-retardant polyester.

If the fabric is made of such a woven or nonwoven fabric, the surface area is increased and the capturing effect is improved.

As shown in fig. 6(d), the flat plate 16l is a resin plate having holes formed at predetermined values.

The resin plate is preferably provided with an opening of a through hole having a diameter of 0.1 to 3mm in view of air permeability, durability, weight reduction, and the like.

As shown in fig. 6(e), a flat plate 16m is a grooved resin plate having grooves 16n, such as semicircular or quadrangular grooves, with a predetermined depth on the surface.

Therefore, the conductive resin can be applied along the grooves, and the flat surface can be smoothed with a doctor blade or the like, so that a predetermined conductive printed layer can be formed.

(7) Conductive resin printing layer

As shown in fig. 3 and 4, as another main structure of the capturing section C, it is preferable to provide a substantially linear conductive resin printed layer as the electrodes 16b and 16 'b for applying a predetermined potential to the flat plates 16a and 16' a.

The reason for this is that by providing such a conductive resin printed layer, a predetermined surface resistance can be adjusted, and the formation thereof is extremely easy and accurate.

In addition, if the conductive resin printed layer is a predetermined conductive resin printed layer, a predetermined voltage is applied between the adjacent flat plates for a long time, and the conductive resin printed layer can also serve as a trap portion with good safety.

That is, a conductive paste is produced by mixing a predetermined amount of a conductive material such as copper, silver, gold, nickel, solder, tin, or stainless steel with an epoxy resin, a polyester resin, a silicone resin, a fluororesin, a polyimide resin, or a phenol resin, which is a main electrical insulating agent.

Then, the conductive paste is printed in a linear shape by a Screen printing method or the like.

Finally, the printed linear conductive paste is heat-cured at 80 to 200 ℃ for 10 to 60 minutes in an oven or the like to obtain a conductive resin printing layer having a surface resistance in the range of 100 to 1000 ohm/□,

The printed linear conductive paste is preferably thermally cured under a predetermined heating condition to obtain a conductive resin printed layer in a range of 200 to 5000 ohm/□, more preferably 300 to 1000 ohm/□.

As shown in fig. 3 and 4, the electrodes 16b and 16 'b to which such a predetermined potential is applied are formed of a conductive printed layer, and when the electrodes are formed in a substantially rectangular shape, the length (L2 and L' 2) thereof is preferably set to a value within a range of 3 to 20cm, more preferably 4 to 15cm, and still more preferably 6 to 10mm, in order to adjust the surface resistance value thereof to a value within a predetermined range.

However, in order to generate a predetermined electric field more easily, the length of the conductive resin printed layer (L2, L ' 2), preferably the length of the flat plate (L1, L ' 1), is preferably shorter than the length of the flat plate (L1, L ' 1).

More specifically, the length (L2, L '2) of the conductive resin printed layer is preferably 95% or less, more preferably 90% or less, and still more preferably 80% or less of the plate length (L1, L' 1).

Similarly, in the case of a substantially rectangular shape, in order to adjust the expressed resistance to a value within a predetermined range, the width (L4) is preferably set to a value within a range of 5 to 50mm, more preferably within a range of 10 to 45mm, and still more preferably within a range of 20 to 40 mm.

(8) Electrode arrangement

as shown in fig. 4(b), when the plurality of electrode-provided flat plates 16 'are viewed from above, the electrodes (conductive resin printed layers) 16' b are preferably formed in a staggered arrangement.

That is, when the center line (L) is assumed along the direction in which the electrodes (conductive resin printed layers) 16 ' b are formed, the electrodes (conductive resin printed layers) 16 ' b are arranged in the left-right direction (or the up-down direction) on the adjacent electrode-carrying flat plates 16 ' with the respective center lines (L) interposed therebetween.

Specifically, as shown in fig. 4(a) to (b), assuming the center line (L), when the plurality of electrode-carrying plates 16 ' are viewed from above, the electrode (conductive resin printed layer) 16 ' b is formed at a position below the center line (L) on one of the electrode-carrying plates 16 '.

Then, an electrode (conductive resin printed layer) 16 'b is formed on the other adjacent flat plate 16' having an electrode, preferably at a position above the center line (L).

The reason for this is that by forming such electrodes (conductive resin printed layers), the electrodes are arranged in a staggered manner when viewed from above, and the electric field generated between the adjacent flat plates is more uniform and has a large area.

6. Suction device

The suction devices 20 and 20' shown in fig. 1 and 2 are not particularly limited as long as they can effectively generate suction flow, but at least one type of suction device such as a fan blade (cross flow fan), a vacuum suction device, a pressure reducing device, and an electric fan is preferably used.

therefore, it is preferable to provide a fan for sucking the small insects by the generated suction flow in the suction part or other parts.

As shown in fig. 1, the suction device 20 is provided above the capturing section C, so that a suction flow as a continuous, vertical air flow from the lower suction section a to the upper capturing section C can be easily generated inside the casing 12.

Therefore, in fig. 1, the marks a and B indicate that such a suction flow is generated and finally discharged to the outside through the exhaust port 12 d.

That is, the small insects can be easily introduced into the housing 12 through the suction port 12b of the suction unit a, and the small insects trapping rate is improved.

7. Ultraviolet lamp

(1) As shown in fig. 2, an ultraviolet lamp 17 is preferably provided above or behind the capturing section C.

The reason for this is that by providing an ultraviolet lamp at such a predetermined position, ultraviolet rays cannot be directly observed from the outside, safety is high, and the effect of attracting small insects can be sufficiently exhibited.

That is, since the small insects generally have a phototaxis induced by ultraviolet rays having a wavelength of 300 to 400nm, the small insects cannot be directly observed from the outside by providing an ultraviolet lamp at a predetermined position, and the trapping ability of the small insects can be remarkably improved.

(2) Photocatalyst member

As shown in fig. 2, a photocatalyst member is provided between the trap part C and the ultraviolet lamp 17 as a part constituting the (D') cleaning part.

For example, titanium oxide (particularly, anatase type) or tungsten oxide which exhibits a photocatalytic effect is mixed or adhered to a mesh material or an open-pore base material having air permeability, and the titanium oxide or the like is activated by an ultraviolet lamp which exhibits an attracting effect without affecting the flow of the suction stream.

In addition, if the photocatalyst member is placed between such a trap portion and the ultraviolet lamp, the situation that a person directly observes from the outside is gradually reduced.
