Description

  The present invention relates to a mosquito trap, and more particularly, to a mosquito trap that can be used both outdoors and indoors without adversely affecting the human body and the environment.

  Since history, damage caused by mosquito-borne infections has not been settled, and many methods have been proposed to combat and avoid mosquitoes. In particular, in recent years, areas that become subtropical due to the effects of global warming have spread, and mosquito-borne infectious diseases such as Japanese encephalitis, malaria, Zika fever and dengue fever have become more problematic than ever. For this reason, regardless of whether it is outdoors or indoors, there is an increasing need to reliably capture or remove mosquitoes using mosquito traps to prevent them from being stabbed by mosquitoes.

  As a method for controlling and repelling mosquitoes, for example, there are known seals and instruments that spread mosquito-repellent components such as mosquito-repelling incense sticks and repelling components that mosquitoes disinfect or control mosquitoes. It has been. However, there are not a few insecticidal and repellent ingredients, which have a negative impact on the human body and the environment, and may spread insecticidal and repellent ingredients such as places where sick people and infants are present and places where pollens are mated using bees. There was a problem that such a mosquito trap could not be used in places where it was not possible.

  In order to deal with such problems, for example, Patent Document 1 discloses a wide range of low-cost and wide-ranging surveys that do not use electric power or materials when conducting population surveys of mosquitoes that transmit diseases in the tropics and subtropics. In order to provide a mosquito attracting and collecting device, a mosquito attracting and collecting device comprising a heating element, a carrier having a mosquito attracting substance, an adhesive layer on the inner surface, and a carbon dioxide generating source is provided. (See claims 1 to 5 of Patent Document 1, paragraphs [0011] to [0028] of the specification, FIG. 1 and FIG. 2 of the drawings, etc.).

  However, the mosquito attracting and collecting device described in Patent Document 1 is a mosquito trap for conducting population surveys only, and has an adhesive layer on the inner wall surface. It was unsatisfactory. In addition, even if it can be captured for a certain period of time, it cannot spread the mosquito attractant for a long time, or it cannot sustain the fever, and it cannot continue to control the mosquito for a long time. It was.

  Further, Patent Document 2 discloses an attracting gas generating means 6 for generating carbon dioxide gas for attracting mosquitoes, an adhesive means 5 for adhering mosquitoes, and heating the adhesive means 5 by generating heat so that the mosquitoes are attached to the adhesive means 5. And a mosquito trap that attracts mosquitoes with carbon dioxide gas generated by the attracting gas generating means 6 and adheres the approaching mosquitoes to the adhesive means 5 (Patent Document 2). Claims 1 to 3, paragraphs [0015] to [0026] of the specification, FIG.

  However, the mosquito trap described in Patent Document 2 has a problem that the heating element is a heating element 2a that generates heat by electricity, and cannot be used without a power source. Further, the generator 6 for generating carbon dioxide also generates carbon dioxide from a carbon dioxide cylinder, and there is a problem that it cannot be easily carried. Furthermore, the adhesive tape 5 is also installed on the outer peripheral side surface of the heating element 2a, and there is a problem that the efficiency is poor both in terms of mosquito extermination rate and thermal efficiency.

  Further, Patent Document 3 is formed of a disinfecting portion 3 having an adhesive sheet 2 for capturing the mosquito 1 on its outer surface and a leg 4 that supports the disinfecting portion 3. The heat storage material 12 that receives light and stores solar heat is accommodated, the heat release of the heat storage material 12 is conducted to the bottom plate 8 of the extermination unit 3, and the lower surface of the bottom plate 8 is provided with the adhesive surface of the adhesive sheet 2 facing downward. A solar-heated mosquito repellent device is disclosed in which the pressure-sensitive adhesive sheet 2 is formed so that it can be heated through the bottom plate 8 by heat radiation of the heat storage material 12 (claim 1 of patent document 3, paragraph [0022] to the specification). [0037], see FIG.

  However, since the mosquito repellent described in Patent Document 3 uses sunlight, it cannot be used indoors, it cannot sufficiently store heat even in rainy or cloudy weather, and cannot be used in rainy or cloudy weather. There was a problem. In addition, there is a limit to attracting mosquitoes only by heat without releasing carbon dioxide, and there is a problem that mosquito control efficiency is poor. Furthermore, the mosquito extinguisher described in Patent Document 3 has a structure in which the adhesive sheet 2 is installed on the lower surface of the heat storage material 12, and in the same way as the mosquito trap of Patent Document 2, heat transfer is also achieved. There was also a problem that the efficiency was poor.

And the mosquito control rate is further improved.

It is a vertical sectional view showing a mosquito trap according to an embodiment of the present invention. It is a perspective view which shows a mosquito trap.

  Hereinafter, an embodiment for carrying out a mosquito trap according to the present invention will be described in detail with reference to the drawings.

  First, a mosquito trap according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a vertical sectional view showing a mosquito trap according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the mosquito trap of FIG.

  As shown in FIGS. 1 and 2, the mosquito trap 1 according to this embodiment includes a housing 2, carbon dioxide generating means 3 provided near the center top of the housing 2, and a bottom plane of the housing 2. The heat source 4 provided over a certain area along the horizontal plane and the adhesive means 5 provided substantially horizontally along the heat source 4 immediately above the heat source 4 and the like, and attracts and captures mosquitoes , Has a function to disinfect.

<Case>
As shown in FIGS. 1 and 2, the housing 2 protrudes downward from a rectangular box-shaped capture portion 20 that forms a bottom portion of the entire housing 2 and the bottom of the four corners of the capture portion 20. Four legs 21, four columns 22 projecting upward from the upper surface (top surface) of the four corners of the capture unit 20, and a roof 23 laid over these four columns 22. , Is composed of.

(Capture part)
The capture unit 20 is mainly composed of a flat rectangular box-shaped capture unit main body 20a, and the adhesive means 5 is placed on the upper surface plate 20b along the horizontal plane of the capture unit main body 20a, and mainly captures mosquitoes. Demonstrate the function to do.

  As shown in FIG. 1, an opening 20c is formed on one side surface of the capturing part main body 20a, and the heat source 4 is accommodated in a freely removable manner. In the capture unit 20 according to the present embodiment, a drawer part 20d is configured to be freely drawn out from the opening part 20c. The drawer part 20d is pulled out by placing a finger on the finger hole 20e, and the heat source 4 housed therein can be easily replaced. It has become.

  Of course, an opening is formed on the upper surface of the capturing part main body 20a, and the upper surface plate 20b is configured to be detachable, and the heat source 4 may be exchanged from the opening on the upper surface of the capturing part main body 20a. Needless to say.

  Further, as shown in FIG. 1, a heat insulating material D is inserted in the capturing unit main body 20 a so as to surround the side surface and the bottom surface of the heat source 4, and the heat from the heat source 4 is transferred to the bottom surface of the housing 2, that is, It does not escape from the bottom and side surfaces of the capturing part main body 20a. For this reason, heat efficiency is good and the suitable temperature which attracts a mosquito can be maintained over a long time of at least 2 hours.

  As the heat insulating material D according to this embodiment, a foamed resin heat insulating material such as polyurethane foam or polystyrene foam is applied. However, the heat insulating material according to the present invention may be an inorganic heat insulating material such as glass wool or rock wool, or a natural heat insulating material such as cellulose fiber, carbonized foam cork, or wool. In short, the heat insulating material according to the present invention is not particularly limited as long as the heat insulating material can be insulated by delaying heat transfer.

  In the capturing unit main body 20a, the upper surface plate 20b is a metal plate having a high thermal conductivity. As shown in FIG. 1, a frame plate 20f thicker than the upper surface plate 20b is installed around the upper surface plate 20b. Yes. By installing the frame plate 20f, the upper surface of the adhesive sheet 50 and the frame plate 20f are flush with each other when the later-described adhesive sheet 50 as the adhesive means 5 is placed on the upper surface plate 20b. The half-moon shaped recess 20g is a finger hook hole when the adhesive sheet 50 is replaced.

(leg)
As shown in FIGS. 1 and 2, the leg 21 is composed of a leg main body 21a made of a cylindrical pipe made of metal or resin, and a cap 21b attached to the lower end (tip) of the leg main body 21a. Has been. The cap 21b is a member made of rubber or resin, and has a function of protecting the end face of the leg 21 and preventing the entire housing 2 from slipping. Of course, the shape and the number of the legs 21 may be set as appropriate, and even if the legs 21 are not all there is almost no influence on the function of removing the mosquito of the mosquito trap 1. However, providing the legs 21 makes it easier to level the housing 2 by inserting some of the legs 21 into the ground when installing in a place with a large amount of unevenness, such as on the ground.

(Pillar)
As with the legs 21, the column 22 is also attached to a column main body 22a made of a metal or resin cylindrical pipe and the upper end (tip) of the column main body 22a, as shown in FIGS. The connecting portion 22b made of metal or resin according to the shape of the roof 23 is formed. Of course, this pillar may be a square pillar, or may be a wall instead of a pillar. In short, the pillars can ensure the vertical space between the roof 23 and the capture unit 20 and need only have an opening serving as an entrance for the mosquito. In the housing 2 according to the present embodiment, the interval between the pillars 22 is an opening on the side surface of the housing.

(roof)
As shown in FIGS. 1 and 2, the roof 23 is a quadrangular roof, and includes a roof main body 23 a and a top portion 23 b configured to be detachable from the roof main body 23 a. A rectangular upper opening 23c is formed in the center of the roof main body 23a, and the top 23b is locked to the upper opening 23c by a locking claw 23d so that it can be attached and detached.

  Of course, the shape of the roof is not limited to a quadrangular shape, and is not particularly limited as long as it is a shape that can prevent precipitation such as rain. However, in consideration of the efficiency of carbon dioxide diffusion by the carbon dioxide generating means 3 described later, in order to diffuse carbon dioxide having a higher specific gravity than air uniformly from one place, a triangular pyramid or quadrangular prism having a vertex at the center is used. It is preferable that the roof is a polygonal or conical roof including the above.

(Garbage net)
Further, as shown in FIG. 1, dust such as dead leaves enters the housing 2 around the opening on the side surface of the housing 2 according to the present embodiment, that is, on the outer surface of the plurality of pillars 22. A dust-removing net N for preventing the above is stretched (not shown in FIG. 2). The size of the mesh of the dust removal net N may be any size as long as it does not hinder the entry of mosquitoes and can prevent large dust such as dead leaves from entering the housing 2. . Even when the mosquito trap 1 is installed outdoors, it is for preventing large garbage such as dead leaves from sticking to the adhesive sheet 50 to be described later and preventing the mosquitoes from being captured by the adhesive sheet 50.

<Carbon dioxide generating means>
Next, the carbon dioxide generating means 3 will be described. As shown in FIG. 1, the carbon dioxide generating means 3 includes a mounting table 30, a generating container 31 mounted on the mounting table 30, water and a carbon dioxide generating tablet 32 placed in the generating container 31, etc. It is composed of

(Mounting table)
The mounting table 30 is a rectangular box-shaped (cuboid) mounting table having an open upper surface, and is fitted inside the upper opening 23c of the roof 23 described above. In addition, a vent hole 30 a for allowing the generated carbon dioxide to pass through is formed in the bottom surface of the mounting table 30. In the illustrated embodiment, an example in which one vent hole 30a is formed is illustrated, but it is needless to say that a plurality of vent holes 30a may be formed.

(Generation container)
The generation container 31 is a container that can store water such as glass or resin, hot water, and the like. The generation container is not limited to the illustrated form, and the material, the shape, and the like are not particularly limited as long as the container can store a liquid.

(Carbon dioxide generating tablets)
The carbon dioxide generating tablet 32 is a tablet containing a carbonate such as sodium carbonate as a main active ingredient, and generates carbon dioxide (carbon dioxide) by dissolving it in water or hot water. Of course, other carbon dioxide generating means such as dry ice can be used. However, a tablet containing sodium carbonate as an active ingredient is preferable in consideration of easy handling, safety, running cost, and the like.

  In addition, as a carbon dioxide generation means, you may generate a carbon dioxide from a gas cylinder. In short, the carbon dioxide generating means according to the present invention may be any means that generates carbon dioxide (carbon dioxide). However, since the gas cylinder is heavy and the ease of carrying the mosquito trap is impaired, lightweight carbon dioxide generating means such as carbon dioxide generating tablets 32 and dry ice are preferable.

<Heat source>
Next, the heat source 4 will be described. As shown in FIG. 1, the heat source 4 according to the present embodiment is mainly composed of a heat storage mat 40 made of a latent heat storage material, and is provided in the drawer portion 20 d of the above-described capture unit 20 that can be pulled out from the capture unit body 20 a. Contained. For this reason, the heat storage mat 40 is configured to be detachable from the housing 2.

(Heat storage mat)
The heat storage mat 40 is a member formed by coating a latent heat storage material with a coating material made of a resin such as aluminum laminate or polypropylene and forming it into a mat shape.

(Latent heat storage material)
The latent heat storage material is a melting point adjusting agent, etc., in order to obtain a desired phase change temperature in a main material combining one or more of inorganic hydrates, paraffins, fatty acids, alcohols and ester compounds. It was prepared by adding the additive. For this reason, the heat storage mat 40 is adjusted so that a predetermined temperature range (30 ° C. to 55 ° C., preferably 32 ° C. to 50 ° C.) whose surface temperature is slightly higher than the skin temperature of a human body or an animal can be maintained for a long time. Yes. As the additive, in addition to a melting point adjusting agent, a phase separation inhibitor, a surfactant, an antioxidant, a supercooling inhibitor, and the like are applicable.

  Specifically, inorganic hydrates include calcium chloride hexahydrate, sodium carbonate 10 hydrate, sodium sulfate 10 hydrate, disodium hydrogen phosphate 12 hydrate, sodium thiosulfate pentahydrate, sodium acetate 3 Water salts, calcium bromide hexahydrate, zinc nitrate hexahydrate, lithium nitrate trihydrate, and the like can be given.

  Examples of the paraffin include long-chain alkanes (chain saturated hydrocarbons) having a large number of carbon atoms such as hebutadecane, octadecane, eicosane, docosan, tetracosane, hexadecane, tricosane, pentacosane, hekitacosane, nonadecane, heicossan.

  Examples of fatty acids include cabric acid, lauric acid, myristic acid, palmitic acid, and stearic acid.

  Examples of alcohols include trimethylolethane, glycerin, dodecanol, cetyl alcohol, stearyl alcohol, polyethylene glycol having a molecular weight of 600 or more.

  Examples of the ester compound include ethyl stearate and butyl stearate.

  According to the heat storage mat 40 according to the present embodiment, by setting the ratio of sodium acetate and water as the latent heat storage material to 5: 5, the surface temperature of the heat storage mat 40 can be set to the human body or animal preferred by mosquitoes. It is 30 ° C. to 55 ° C., which is slightly higher than the skin temperature, preferably 32 ° C. to 50 ° C., and can be maintained for a long time of at least 2 hours or more.

  In addition, since the heat storage mat 40 can maintain the predetermined temperature for a long time of 2 hours or more in this way, even when the mosquito trap 1 is carried and used for work that takes a certain period of time outdoors or indoors such as farm work, the heat storage mat 40 is used. The mosquitoes can be controlled efficiently without replacing the mosquitoes.

  In addition, the heat storage mat 40 according to the present embodiment, as described above, is covered with the heat insulating material D on the side surface and the bottom surface other than the top surface on the adhesive sheet 50 side described below that needs to be set to a predetermined temperature. In this respect as well, it is possible to maintain a predetermined temperature for a long time, which contributes to an improvement in the mosquito control rate.

  The preferable temperature range of the surface temperature of the heat storage mat 40 described above is based on the viewpoint obtained from known literatures and experiments, and the surface temperature of the adhesive sheet 50 described later is the skin temperature of a human body or an animal (28 ° C to 42 ° C). ) So that it can be calculated back from there.

  In addition, although the latent heat storage material which is easy to set to a desired temperature range was illustrated and demonstrated as a heat source, the other heat storage material may be sufficient as the heat source which concerns on this invention. In addition, instead of the heat storage material, a heat generating material that generates heat, such as a heat generating material that uses the oxidation action of iron, such as a disposable body warmer, can be used as a heat source. Furthermore, although it is inconvenient to carry, as the heat source according to the present invention, a device capable of maintaining a constant temperature with electric power such as a battery such as an electric heating apparatus can be used.

<Adhesive means>
Next, the adhesion means 5 will be described. As shown in FIG. 1, the adhesive means 5 according to this embodiment includes an adhesive sheet 50 in which an adhesive layer is formed on the front surface (upper surface) and a reinforcing cloth such as a nonwoven fabric is disposed on the back surface (lower surface). And this adhesive sheet 50 is installed in the frame plate 20f on the upper surface plate 20b of the capture part 20. In this way, since the adhesive sheet 50 is inexpensive and easy to replace, the mosquito is captured by the adhesive force of the adhesive layer and discarded as it is, and is replaced with a new adhesive sheet 50. Very easy.

  Examples of the adhesive layer include an adhesive layer made of a resin such as polybutene, polyisobutene, styrene-isoprene block copolymer, acrylic resin, and, if necessary, an ultraviolet ray inhibitor, an antioxidant, a viscosity modifier, etc. Known additives may be added. Of course, the adhesive layer is not limited to those illustrated, and the material and the like are not particularly limited as long as the adhesive layer has an adhesive force that prevents the mosquito from being captured and returned again.

  In general, the mosquito's flight ability is weak, and it is considered difficult to stop the blood sucking target while rising during the flight. However, as described above, the adhesive means 5 according to the present embodiment is provided with an adhesive layer on the upper surface of the bottom of the housing 2 that is shaded. That is, the adhesive means 5 according to the present embodiment is the adhesive means that the mosquito misidentifies as a blood-sucking object because the adhesive layer is formed on the horizontal surface in the housing 2 that is shaded and does not receive direct sunlight and avoids wind and rain. It is thought that the catch rate of mosquitoes will be greatly improved because it can be stopped simply by stopping flapping on and down.

  In addition, it is said that the human mosquitoes (flyfish mosquitoes) have a habit of gathering in dark colored objects such as black, and in that respect also, the mosquitoes are efficiently captured and exterminated by the adhesive means 5 installed on the shaded plane. be able to. Note that house mosquitoes such as mosquito mosquitoes sense infrared rays and come from a heat source.

[How to use mosquito traps]
Next, the usage method of the mosquito trap 1 according to the present embodiment will be described with reference to FIGS.
First, the heat storage mat 40 which is the heat source 4 of the mosquito trap 1 is heated. Since the heat storage mat 40 is configured to be detachable from the housing 2 as described above, it can be easily removed and heated by an external heating means.

  Specifically, the heat storage mat 40 is removed and heated to a desired temperature (55 ° C.) or higher by boiling water using a container such as a pan. Of course, it goes without saying that the heat storage mat 40 may be heated by other heating means.

  Next, the heated heat storage mat 40 is accommodated in the drawer part 20d of the capture part main body 20a. At this time, since the finger holes 20e are formed in the housing 2, it is easy to put a finger on the finger holes 20e to pull out the drawer portion 20d or to house the heat storage mat 40 in the capturing portion main body 20a. .

  In addition, the adhesive sheet 50 is set in the frame plate 20f on the upper surface plate 20b of the capture unit 20, and the top 23b of the roof 23 is removed, and water is put on the mounting table 30 of the carbon dioxide generating means 3. 31 is placed. Then, carbon dioxide generating tablets 32 are placed in the generating container 31 to generate carbon dioxide. Needless to say, the adhesive sheet 50 may be set or carbon dioxide may be generated before the heat storage mat 40 is heated.

  Next, a dust removal net N is stretched on the side opening of the housing 2. Thereby, the installation of the mosquito trap 1 is completed. Thereafter, mosquitoes are attracted by carbon dioxide and heat, stop on flapping and stop on the pressure-sensitive adhesive layer of the pressure-sensitive adhesive sheet 50, and are captured one after another.

  In the mosquito trap 1 installed in this way, the capture and removal of the mosquitoes are completed if the adhesive sheet 50 on which the mosquitoes are captured is rolled up and discarded after a certain period of time has elapsed, such as when the outdoor work is completed. For this reason, post-treatment after capturing mosquitoes is extremely easy.

  In addition, the adhesive sheet 50 is peeled off using the half-moon-shaped depression 20g, replaced with a new one as described above, and the carbon dioxide generating tablet 32 is added or added, and the heat storage mat 40 is heated again as described above. Then, mosquitoes can be captured and removed repeatedly. For this reason, a power supply and a large-scale apparatus are unnecessary, and it can install and use anywhere indoors or outdoors without having a bad influence on a human body or an environment.

[Effect of mosquito trap]
According to the mosquito trap 1 according to the embodiment of the present invention described above, the entire device of the mosquito trap 1 is accommodated in the compact housing 2 and can be easily carried. In addition, because it attracts mosquitoes with carbon dioxide and heat, it does not require a power source or a large-scale device, and can be installed anywhere indoors or outdoors without adversely affecting the human body or the environment.

  The process by which mosquitoes catch prey and move to blood-sucking behavior is thought to sense carbon dioxide and approach heat, and then recognize heat as a landing point (skin blood-sucking point) ("Mosquito Science" Araki Osamu 2007 See Nikkan Kogyo Shimbun). In addition, the head of the mosquito has a sensory organ called a “hairy sensory sensation” that senses carbon dioxide, and that sensory device has the ability to sense carbon dioxide gas exhaled by humans and animals from a distance of several hundred meters. . In addition, the ability to sense the heat generated from the body temperature of a human body or an animal (mammal) is said to be able to feel a temperature difference of 15/100 ° C. at a distance of 1.2 cm (“the sixth sense of animals” [See Maurice Burton, 1975) Considering these facts, it is clear that the important factors for attracting mosquitoes are carbon dioxide and heat.

  According to the mosquito trap 1 according to the present embodiment, the mosquito is attracted by the carbon dioxide generated by the carbon dioxide generating means 3 and the heat of the heat source 4, and therefore the effect of attracting the mosquito is extremely high. In addition, since the adhesive means 5 for catching mosquitoes is provided immediately above the heat source 4, there is little loss in heat transfer and extremely good thermal efficiency. In addition, the mosquito trap 1 can be used for a long time without a large-scale device such as a power source.

  In general, the flight ability of mosquitoes is weak, and it is thought that it is difficult to stop a blood-sucking target while rising during flight. For this reason, like the adhesion means 5 of the mosquito trap 1, the mosquito falls down on the adhesion means 5 by forming an adhesion layer on the horizontal surface in the housing 2 that is shaded and does not receive direct sunlight and avoids wind and rain. This makes it easier to catch mosquitoes efficiently and increases the extermination rate.

  Moreover, since the heat storage mat 40 which is the heat source 4 of the mosquito trap 1 is configured to be detachable with respect to the housing 2, it can be installed anywhere indoors or outdoors without the need for a power source or the like, and is heated. It can be used repeatedly and the running cost is low.

  Further, the heat storage mat 40 is a latent heat storage material adjusted so that the temperature range of the surface temperature of 30 ° C. or more and 55 ° C. or less can be maintained for 2 hours or more, and the surface excluding the adhesive sheet 50 is covered with the heat insulating material D. Therefore, mosquitoes can be controlled efficiently over a long period of time.

  In addition, according to the mosquito catcher 1, the adhesive means 5 is the adhesive sheet 50 configured to be detachable from the heat source 4, so that the processing after capturing the mosquito is discarded together with the adhesive sheet 50. Simply replace the adhesive sheet with a new one. For this reason, according to the mosquito trap 1, the post-treatment is extremely simple and inexpensive, so that the running cost can be reduced. In addition, there is a half-moon shaped recess 20g and the like, and the replacement of the adhesive sheet 50 is extremely easy.

  As described above, the mosquito trap according to this embodiment has been described in detail. However, each of the above-described or illustrated embodiments is merely an embodiment embodied in carrying out the present invention. The technical scope of the invention should not be limitedly interpreted.
