Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical bottle for attaching a pesticidal device to an insecticidal device to evaporate an insecticide from an absorbent core to the outside.

[0002]

2. Description of the Related Art In order to kill mosquitoes and the like that have entered a building, insect-killing instruments are used in an outer case having an outside air intake and a transpiration port, compared with insect-killing instruments having a heating element.
By removing the cap of the medicine bottle 11 as shown in FIG. 5 and mounting the same, and heating the upper part of the liquid absorbent core of the medicine bottle, the insecticidal liquid is raised in the liquid absorbent core and evaporated to the outside. .

[0003] As a heating method based on such a combination of a medicine bottle and an insecticidal device, as shown in FIG. Direct heating system that transfers heat by conduction, Fig. 4
As shown in (b), the heating element 1 is connected to the upper end of the liquid absorbing core 13 and another buffer material 3 (to prevent the heat absorbing element 1 from directly contacting the liquid absorbing core 13 to prevent the liquid absorbing core 13 from being damaged. Indirect contact heating method (indirect heating method in a broad sense) in which heat is transmitted through heat conduction by contact through an inorganic glass or an organic glass, etc.
As shown in (c), a heat radiating ring 2 in which a liquid absorbing core 13 is surrounded at a predetermined interval is adopted as the heating element 1, and heat is transmitted by heat radiation from the heat radiating ring 2. A heating method (indirect heating method in a narrow sense) is adopted.

[0004] The direct heating method shown in FIG.
In the indirect contact heating method shown in FIG. 2B, heat is transmitted to the liquid absorbing core 13 by using heat conduction, so that good thermal efficiency can be obtained. 1
It cannot be denied that the presence of such a heating element 1 hinders the insecticide from evaporating upward.

Further, in the case of the direct heating method shown in FIG. 4A, the heating element 1 and the liquid absorbing core 13 come into direct contact over a wide range, and the liquid absorbing core 13 is deteriorated and smoked. We cannot avoid the disadvantage of being easy.

On the other hand, the indirect heating method shown in FIG.
Since the heat dissipating ring 2 for transmitting heat to the upper part of the liquid absorption core 13 is present around the liquid absorption core 13, there is no disadvantage such as the direct heating method and the indirect contact heating method, but the heat transmission is radiated. Therefore, compared to the direct heating method or the indirect contact heating method, the heat efficiency is low, and to make the liquid absorption core temperature the same level, an extra amount of heat is required. When the calorific value is the same, the temperature of the liquid absorbent core 13 must be reduced in many cases.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned situations of the prior arts, and has been made in consideration of the above-mentioned circumstances. It is an object of the invention to provide a configuration.

[0008]

In order to solve the above-mentioned problems, a configuration of the present invention is to provide a heating element in a case having an outside air inlet and a transpiration port, and a heat radiating element for transferring heat from the heating element. In the medicine bottle attached to the insecticide device provided with the ring, the upper part of the liquid absorption core of the medicine bottle is in contact with a part of the heat radiating ring, and in order to make the arrangement relationship apart from the remaining part, The medicine bottle is characterized in that the diameter of the cross section in the upper part of the absorbent core is not uniform.

[0009]

In the conventional indirect heating method as shown in FIG. 4 (c), the heat radiating ring 2 has a substantially cylindrical shape.
Therefore, the inside of the transverse cross section of the heat radiating ring 2 is substantially circular, and the transverse cross section of the liquid absorbing core 13 of the medicine bottle 11 inserted into the heat radiating ring is also substantially cylindrical with a uniform diameter. The shape is formed.

On the other hand, the diameter of the liquid absorbent core 13 of the medicine bottle 11 according to the present invention in the upper transverse section is shown in FIG.
As shown in FIGS. 1 (a) and 1 (b), the medicine bottle 11 which is formed non-uniformly and requires such an absorbent core 13 is as shown in FIG. 1 (c). 1 (a) shows a case where the cross section in the transverse direction is substantially elliptical, and FIG.
(C) shows the case where the transverse section is substantially rectangular. ).

[0011] Such a medicine bottle 1 according to the present invention.
2 is attached to a conventional insecticidal device for indirect heating, as shown in FIGS. 2A and 2B, the portion having the maximum diameter of the liquid absorbent core 13 and the region in the vicinity thereof And in a state where it is in contact with the inner surface of the heat radiating ring 2, and in the remaining area, the two can be separated from each other (see FIG. 2).
(A), (b) shows the case where the transverse cross section of the liquid absorption core 13 is substantially rectangular. ).

Incidentally, the transverse cross section of the upper part of the absorbent core 13 of the present invention is not limited to the substantially elliptical shape and the substantially rectangular shape as shown in FIGS. Is non-uniform, if it is inserted into the indirect heating radiating ring 2 having a substantially cylindrical shape, if it can be partially contacted and partially separated, any shape can be realized. Is also good.

In the present invention, it is possible to use both the direct heating system and the indirect heating system by partially contacting the heat radiation ring 2 and the liquid absorbing core 13 and separating them. In addition, even if the direct heating method is adopted, the position where the heat radiating ring 2 and the liquid absorbing core 13 come into contact with each other is
As shown in FIGS. 4 (a) and 4 (b), since it is not above the liquid absorbent core 13, it does not hinder the evaporation of the chemical.

On the other hand, in a region where the liquid absorbing core 13 and the inner surface of the heat radiating ring 2 are separated from each other, indirect heating is clearly realized, and the air entering from the outside air inlet rises and evaporates through the gap between them. The advantage of the indirect heating method, which evaporates smoothly from the mouth, can be used as it is.

Further, in the present invention, by the above-described partial contact, efficient heat transfer can be realized as in the case of the direct heating method, and the same heat generation can be achieved as compared with the conventional indirect heating method. When a body is used, a larger amount of volatilization can be obtained.

[0016]

EXAMPLE As shown in FIG. 3 (a), the transverse section of the upper part of the liquid absorbent core 13 is substantially square, the maximum diameter is about 10 mm, and the minimum diameter is about 7.1 mm (10 / √2 mm). Of a heat dissipating ring 2 having an inner diameter of about 10 mm and a length (vertical width) of 10 mm, which is fitted with an insecticidal device having a heat dissipating ring 2. The outer surface of the liquid core 13 is partially in contact with the vicinity of the uppermost portion of the liquid absorbent core at the maximum diameter and in the vicinity thereof, and is separated in other regions, and is heated by the heating element 1 with power consumption of about 5 watts. Was performed.

When the temperature of each part was measured, the liquid absorption wick 1 was measured.
The temperature of the surface of the heat radiation ring 2 is 134 ° C. at the part in contact with the inside of the heat radiation ring 2 (the part with the largest diameter at the upper part of the liquid absorption core), Is 127 ° C., the average temperature of the portion of the inner surface of the heat radiating ring 2 that is in contact with the liquid absorbing core 13 is 134 ° C., and the portion farthest from the liquid absorbing core 13 Was 137 ° C.

The attached drug bottle has a capacity of 50 m, and 1.3 g of pinamine D forte, 70 g of butyl diglycol, and BH are added to the drug bottle.
To 0.5 g of T was added 45 m of an aqueous insecticidal solution having purified water added to make the total amount 100 m.

After the start of volatilization, 10 hours, 120 hours, 240 hours and 360 hours have passed, plastic cylinders each having an inner diameter of 20 cm and a height of 43 cm are stacked in two steps, and a 16 mesh wire mesh is placed thereon. A cylinder (both for placing a test mosquito) having an inner diameter and a height of 20 cm, which is divided up and down, is placed thereon, and a cylinder having an inner diameter of 20 cm and a height of 20 cm is further placed thereon. The four-tiered cylinder is placed on a table, and a heated chemical liquid evaporator is placed in the center of the table to evaporate the insecticide liquid. Then, about 20 female mosquitoes for test are released on the upper cylinder,
Observe the number of turns of the mosquito over time. Twenty minutes after exposure, all test mosquitoes were transferred to a clean polyethylene container, given 3% sugar water, and examined for mortality after 24 hours of storage.
A knockdown test using KT-50 (a test in which 50% of the test mosquitoes reach the knockdown state) was performed.

[0020]

COMPARATIVE EXAMPLE A heating element 1 consuming the same electric power as that of the above-described embodiment is used, and the inner side surface is about 10 mm in a transverse section.
In the insecticidal device having a heat radiating ring 2 having a circular shape according to the diameter of 10 mm and having a height of 10 mm, the same insecticide solution as in the above embodiment is accommodated, and the diameter of the transverse section is approximately 7 mm. A medicine bottle 11 having a cylindrical liquid absorbent core 13 was attached.

By the mounting, as shown in FIG. 3B, the inner surface of the heat radiating ring 2 is separated from the outer surface of the liquid absorbing core 13.

When the temperature of each part during heating was measured in the same manner as in the above embodiment, the average temperature of the inner surface of the heat radiation ring 2 was 135 ° C., and the surface temperature of the liquid absorbing core 13 was 120 ° C.
Met.

Then, an insecticidal efficacy test and a knockdown test were performed in the same manner as in the above example.

In the insecticidal efficacy tests according to the above Examples and Comparative Examples, 100% insecticidal efficacy was obtained.

The time required for KT-50 of the comparative example at the stage of 10 hours after the start of volatilization was 190 seconds.
The relative ratio of the KT-50 test by the numerical value obtained by dividing the above 190 (second) by the time (second) required for 50 is as shown in the following table.

As is clear from the comparison between the embodiment and the comparative example, in the medicine bottle according to the present invention, the effect on KT-50 is clearly higher than that of the conventional medicine bottle having a substantially cylindrical liquid absorbing core. Shows excellent results.

Such a result is based on the combined use of the direct heating method and the indirect heating method by bringing the heat dissipating ring 2 into contact with a part of the surface of the liquid absorption core 13, and is more effective than the conventional indirect heating method. It is considered that this is due to efficient volatilization.

[0028]

As described above, in the present invention, by adopting a part of the direct heating method, a smooth rise of the insecticide is exhibited while maintaining good heat generation efficiency, as in the case of the indirect heating method. In addition, the insecticidal efficiency can be further improved as compared with the case of the pure indirect heating method.

Moreover, the area of the region where the uppermost part of the upper part of the substantially rectangular liquid absorbing core and the vicinity thereof come into contact with the substantially cylindrical heat radiating ring is the conventional area as shown in FIG. Since the contact area is smaller than the contact area of the direct heating method, it is possible to minimize the damage and smoking of the liquid absorption core itself due to the direct heating.

As described above, in the present invention, the technical improvement as described above can be obtained by devising the shape of the liquid-absorbing wick, so that the value thereof is enormous.
