Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest control apparatus for controlling pests by volatilizing a drug from a drug support holding a drug, and more particularly to a pest control apparatus capable of easily supplying a drug to the drug support. About.

[0002]

2. Description of the Related Art Conventionally, as a means for forcibly volatilizing a drug, there has been known a method for volatilizing a drug by blowing air. As an example, a sublimable insect repellent such as naphthalene is stored in the device, the outside air is sucked through the suction hole of the device, the volatile component of the insect repellent is volatilized in the device, and the air containing the volatile component of the insect repellent is removed. Insect control device discharged from the exhaust port
954) is known. In addition, a method is known in which a diffusion material holding a room-temperature volatile agent is driven by a driving unit in the form of, for example, a fan, and the volatile agent is diffused to kill insects. This method is one of the methods of volatilizing a drug under blowing and non-heating conditions.

Further, in order to increase the volatilization amount of a volatile chemical, a honeycomb-like material such as a cardboard is known as a chemical support for holding the chemical. Such a honeycomb-shaped body can obtain a certain strength from its structural characteristics and can hold a large amount of a drug,
In addition, there is an advantage that a large surface area can be obtained and air resistance is small. However, on the other hand, in the case of using a drug which can obtain an effect with a small amount, it is not necessary to volatilize a large amount of the drug, and it is difficult to reduce the size of the apparatus when trying to reduce the size.

[0004]

Further, when a volatile drug is volatilized by using a drug holder for holding a volatile drug, the drug to be volatilized is invisible because the volatilized drug is invisible. It is important to be able to determine the end point, that is, the end point, but if an indicator or the like is provided on the drug holder to determine the end point, it is difficult to see the indicator or to determine the end point Since there are disadvantages such as individual differences, it is necessary to be able to reliably determine the end point. Further, when a drug is volatilized using such a drug holder, the amount of the drug held by the drug holder is limited. It is necessary to provide a means capable of continuously and uniformly supplying the water.

[0005]

The present invention has solved the above-mentioned problems by the following means. (1) A drug holding body whose surface constitutes a drug volatilization surface, and a drug supply means for supplying a drug to the drug volatilization surface of the drug holding body, wherein the drug supply means contains a gel containing a drug. A pest control device comprising: (2) The pest control apparatus according to (1), wherein the medicine holding body is a net-like body or a honeycomb-like body. (3) The insect pest control device according to (1), wherein the medicine holding body is made of a twisted yarn, a modified cross-section yarn, a hollow fiber, or a surface-processed yarn. (4) The material of the drug holding body constituting the drug vaporizing surface is selected from the group consisting of cotton, polyamide, polyester, silk, wool, rayon, acetate, and polyacryl. The pest control apparatus according to any one of 1) to (3). (5) A drug composition comprising a gel-like substance containing a drug for use in the pest control device according to any one of (1) to (4).

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, as a drug holding body forming a drug volatilizing surface, any holding body capable of forming a drug volatilizing surface can be used. However, since a holding body having a large surface area is preferred as a holding body having a drug volatilization surface capable of increasing the amount of drug volatilization, its shape is restricted to some extent. Furthermore, since it is necessary that the flow of the drug from the gel-like material to the drug volatilization surface is good, it is preferable to satisfy the condition. From these points, examples of the medicine holding body forming the medicine volatilization surface include a net-like body and a honeycomb-like body. In the case of a net-like body, the specific surface area per unit weight of the net-like body is very large, and the specific surface area can be large in terms of the weight of the net-like body provided in a unit volume of space. In the honeycomb body,
A large surface area can be formed in the direction of the air flow, and a structurally strong form can be obtained. It is preferable that the net-like body is composed of fibers, and as the fibers, use is made of a surface-processed yarn such as a twisted yarn or a fluffed fiber, a modified cross-section yarn, a hollow fiber or a surface-processed yarn. Further, as a material of the fiber, a material having a liquid absorbing property is preferable. The fibers can be used for other forms of drug carriers.

[0007] The form of the net-like body preferably has a mesh opening of 8 to 100 mesh. The thickness of the fibers or yarns constituting the net-like body is required to ensure sufficient strength and medicine to constitute the net and to secure a sufficient drug vaporizing surface, for example, 30 to
Preferably, it is 500 denier, but it also relates to the above-mentioned structure of the fiber. The fiber or yarn may be a single fiber or a twisted yarn. The above fibers or yarns may be simply referred to as “fibers” below. When it is not sufficient to form a sufficient drug volatilization surface with only one layer, the net-like body may have a form in which two or more nets are stacked. More specifically, when gauze is used as the net-like body, two or more gauze layers can be used. Further, the honeycomb-shaped body may have a surface area extended in the ventilation direction.

[0008] Although the above-mentioned drug holding body, especially the above-mentioned net-like body, initially holds a drug therein, the holding amount of the drug is not so large. Therefore, it is necessary to continuously supply the drug to the net-like body or the like. Therefore, in the present invention, a medicine supply means is provided in contact with the medicine holder. As the medicine supply means, for example, a medicine holding section for holding a medicine can be provided. As for the form of the medicine, it is preferable that the medicine has an appropriate fluidity in order to uniformly supply the medicine from the medicine supply unit onto the medicine holding body. For example, the liquid form of the drug,
In other words, in the medicine supply section that holds and supplies the drug solution, by holding the drug solution in a gel-like material, the drug solution can be held well, and at the same time, the drug solution can be uniformly supplied onto the drug holder.

In the case where the liquid medicine is contained in the gel-like material and the gel-like material is held in the medicine holding body, for example, by contacting the medicine supply section with one side of the medicine holding body, the medicine holding body is formed. When attempting to supply the drug solution, the drug can be sufficiently supplied by bringing the drug supply unit into full contact with only one side of the drug holder. This is because the gel-like material is elastic and easily deformed, so that the gel-like material comes into good contact with the surface of the medicine carrier. Such a gel is
In order to prevent the drug from volatilizing from the surface, the drug is accommodated in a container, one surface of the container is opened, and the drug holder can be brought into contact with the gel-like material exposed at the opening.

On the other hand, in the case where a drug supply section formed by impregnating a sponge with a drug solution is used, the sponge has good contact with the surface of the net-like body particularly when the drug holding body is a net-like body. Also, it is necessary to impregnate the sponge with a sufficient amount of the chemical solution in order to sufficiently transfer the chemical solution from the sponge to the net-like body, but doing so may cause problems such as dripping from the sponge. May cause. In addition, the use of a medicine supply unit in which a medicine is contained in a container simplifies the structure. If the medicine is colored, the end point can be easily determined, and means for replacing the medicine container can be adopted. it can. In the form using a chemical solution container, when supplying the chemical solution from the chemical solution container to the net-like body,
For example, when the dropping method is used, the net-like body is thin, and care must be taken so that the supply to the net-like body is not uneven. Further, even in the case of the wick type, it is necessary to prevent the contact between the wick and the net-like body from becoming insufficient when supplying the net-like body.

[0011] In the present invention, since a gel-like substance containing a medicine is used in the medicine supply section, even when the medicine holding body is a net-like body, a contact portion with the medicine holding body can be widened. To make a gel, use a gelling agent,
Among the known gelling agents, those which can be preferably used include, for example, metal soaps, fatty acids and salts thereof, metal salts of long-chain alkali phosphoric acids, hydroxy acids, POE alcohol ethers, fatty acid esters, glycerin Examples include fatty acid esters and fatty acid ethanolamines. Regarding the properties of the gel-like material, the viscosity of the gel-like material is large and may be relatively hard, so that the drug solution in the gel-like material oozes out and migrates to the drug holding body, Further, the viscosity of the gel-like material may be low, and the drug solution may flow out of the drug supply section in the form of a viscous liquid and migrate to the drug carrier. In the latter case, the gelling agent may be used to volatilize the drug in the drug carrier. This has the advantage that it spreads over the surface and increases the area of the drug vaporizing surface, or acts to increase the amount of drug held on the drug vaporizing surface. In particular, when the medicine holding body is a net-like body, there is an advantage of increasing the area of the medicine volatilization surface.

The medicine to be supplied to such a medicine carrier is
No particular limitation is imposed on the components for controlling pests such as insecticides or insect repellents, and agents that can obtain a certain effect by volatilizing the components in the air.

Increases stability against oxidation and the like.

Since the above-mentioned pest control component and / or various kinds of drugs are supplied to the drug holder, the amount of the drug held by the drug holder is not particularly limited. When the drug (such as a pest controlling component) is contained in a gel, the gel is usually kept in the gel in a range of 2 mg / g to 500 mg / g, preferably 5 mg / g to 100 mg / g. be able to. A specific example of the supply amount of the chemical solution per day to the net is as follows. For example, when a net having a size of 60 × 60 mm is used for 12 hours / day for one month, 30 to 360 mg / net of transfluthrin is used. , 50-750mg / net for terrareslin, S1

In such a net-like body, for example, air is blown at a rate of substantially 0.1 to 10 liter / second · m ^{2 in} the penetrating direction to volatilize the held medicine in the air.
When the air volume is less than 0.1 liter / second · m ^2, it is difficult to secure a sufficient volatilization amount, which is not preferable. If it exceeds 10 liters / second · m ² , the required power is undesirably large. In order to volatilize the medicine, for example, a blower may be used. FIG. 1 shows a pest control device 1 that volatilizes a drug from such a net. This pest control device 1
Is composed of a medicine room 3 having a net 5, a fan room 8 having a DC motor 10 and a fan 9, and a battery housing room 13 for housing a battery 14. An entrance frame 2 is provided on the upper surface of the pest control device 1, a net 5 is stretched by a support frame 4 in a medicine room 3 therebelow, and a lower part is opened at one end of the net 5, and three sides are drug impermeable. A box-shaped medicine holding / supplying unit 6 made of the above material is loaded, and the inside of the medicine holding / supplying unit 6 is filled with a gel-like substance 7 containing a medicine. 5 is supplied to the whole.

A DC motor 10 is provided in the fan chamber 9 below the medicine chamber 3, and a fan 11 (in this case, a sirocco fan) is provided at the tip of a drive shaft 12 of the DC motor 10. An exhaust port 12 is formed.
The battery accommodating chamber 13 accommodates a battery 14 and has a terminal (not shown) in contact with its electrode, and the terminal is connected to the DC motor 10 via an operation control circuit (not shown). Therefore, a current flows from the battery 14 to
When the fan 11 rotates, the outside air is taken in from the upper intake port and passes through the net 5, which is a volatilization surface, to volatilize the medicine to become a gas containing the medicine. After passing through the pest control device 1 and passing through 12, the pests are controlled. The range of the flow rate from the exhaust port 12 is, for example, 0.1 liter / second to 10 liter / second, preferably 0.2 liter / second to 6 liter / second.

In addition to the case where the installation of the fan 11 is fixed as described above, the fan 11 can also be installed so as to be freely movable.
1 may be of a type that can swing his or her head to the left or right, or may be of a type that can be moved up and down.

The fan 11 is formed by providing a plurality of inclined blades radially on the drive shaft 12. Therefore, the fan 11 and the DC motor 10 constitute a so-called axial flow type blowing means. In addition, the air blowing means may be a so-called multi-blade air blowing means (sirocco fan) which has a large number of blades formed in a cylindrical shape in a direction parallel to the drive shaft 12 and blows air in a direction orthogonal to the drive shaft 12. . These fans 1
The weight of 1 is 3 from the relation with the load that can be driven by a battery.
A lighter weight than 0 g is suitable. For example, a propeller fan is about 3 to 15 g, and a sirocco fan is about 7 to 15 g. Further, a brushless axial flow fan or the like having a built-in IC can be used.

As the motor for driving the fan 11, various motors can be used, and those which can be driven by a current from a home power supply or those which can be driven by a battery may be used. The one which can be driven by is preferable because it is easy to move, and is simple and convenient. In particular, when a DC motor having a current consumption of no more than 100 mA under no load is used and is driven by a battery, a sufficient amount of drug volatilization and long-time operation can be achieved. Note that such a device may include a control circuit having a sensor, a timer, and the like.

[0028]

The present invention will be described in detail with reference to the following examples. However, the present invention is not limited to only these examples. Example 1 In this example, a net was formed by using fibers of the following four types of materials as a net-shaped medicine holder.

(Test Method) Drug diffusivity A 60 mm × 60 mm net made of the above-mentioned material was brought into contact with a drug holding portion holding a gel-like substance containing 100 mg of a drug, and provided with a propeller fan having a diameter of 60 mm. The drug was volatilized from the net by extending the propeller fan of the pest control device in front of the suction port and rotating the propeller fan with a motor that operates at a voltage of 3 V. At that time, the volatilization amount (per hour) of the drug was measured. At that time, the air volume was measured at the same time. This is due to the different air resistance due to the different mesh of the net,
This is because the ventilation amount is different. (Test results) The test results are shown in Table 1.

Net cotton (gauze) 60mm x 60mm 30 mesh Drug-containing gel-like substance To 1.8 g of the drug terrareslin, 12-hydroxystearic acid as a gelling agent was added and dissolved by heating, and then cooled to prepare a gel containing the drug.

(Test Method) A drug-containing gel was brought into contact with a gauze of 60 mm × 60 mm (30 mesh) so that the drug was diffused from the gel to the net, and a propeller fan was rotated by a motor at 1000 rpm. At 40 ° C. for 24 hours to evaporate the drug from the net. Further, the above-mentioned fan was operated at 25 ° C., and the volatilized active ingredient was collected by suction using a silica gel trap, and extracted and quantified. In the former, the remaining amount (mg) of the drug in the gel containing the drug was measured for each number of days of volatilization. (Measurement Results) The measurement results are shown in FIGS. Terraresulin showed a stable volatilization pattern for a long time. FIG.
Shows a graph showing a change in the amount of drug volatilized with respect to the number of test days, and FIG. 3 shows a graph showing a change in the remaining amount of the drug in the drug-containing gel with the number of test days. Since the remaining amount decreases in proportion to the elapsed days, it is also suitable as a function as an indicator.
