[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insecticidal solution in which an insecticide contained in a heated evaporator is sucked up by an absorbent core, and the upper portion of the absorbent core is heated by a heater to evaporate the insecticide into the air. And a method for killing insects by heating.

[0002]

2. Description of the Related Art Heating evaporators used in electric heaters are of various shapes, and the height of the liquid absorbing core and the shape of the lower portion of the heating evaporator are not constant. . For this reason, a heating evaporator to be used for each electric heater is predetermined.

[0003] Further, the importance of the positional relationship between the liquid absorbing core and the heater has not been recognized. Therefore, when a different heating evaporator other than the determined heating evaporator is used, not only does the height of the absorbent core change, but also the gap between the absorbent core and the heater becomes inconsistent, and the evaporation efficiency deteriorates. There was a problem.

[0004]

SUMMARY OF THE INVENTION Therefore, the heat evaporation body according to the present invention solves the above-mentioned problems of the conventional heat evaporation body, and provides a predetermined heat evaporation body even when different heating evaporation bodies are used. An object of the present invention is to provide an optimum transpiration efficiency as in the case of using the transpiration.

[0005]

Therefore, in the present invention, there is used a pyrethroid-based insecticide and a heat-transpired insecticidal solution for a liquid-absorbing wick comprising a solvent such as water, butyldiglycol, alcohol, silicone oil, and kerosene. In the heat evaporation insecticidal method in which the insecticide is evaporated by heating the upper part of the absorbent core with a heater while sucking up the insecticide with the absorbent core, a ring-shaped width adjustment for fitting the bottom of the container body 1 of the heated evaporant body. The body 4 and a height adjuster 7 having a convex portion 7b on the upper surface fitted into a lower portion of the width adjuster 4 are provided between the bottom lid of the electric heating type heater main body and the lower portion of the heating evaporator so that the heater sucks. The outer periphery of the liquid wick was surrounded with a certain gap, and the height of the tip of the liquid wick was made to coincide with the height of the upper end of the heater.

According to the present invention, since the above-mentioned means is applied, the following operation is performed. In the present invention, the width adjuster 4 and the height adjuster 7
Is provided between the bottom lid 8 of the electric heating type heater main body and the lower part of the heating evaporator, and the width adjuster 4 allows the heater 10 to surround the liquid absorbing core 5 with a constant gap 11 and has a high height. The height of the tip of the liquid absorbent core 5 and the height of the upper end of the heater 10 are made to coincide with each other by the adjusting body 7, so that the heater 10 uniformly heats the liquid absorbent core 5 and the liquid absorbed by the heater 10 is heated. The area of the core 5 is maximized. Therefore, it is a position where the transpiration efficiency is the best.

[0007] In the present invention, the heat transpiration insecticidal solution 2 for the absorbent core is prepared by adding a solvent such as water, butyl diglycol, alcohol, silicone oil, kerosene, etc. What added various additives, such as an inhibitor and a volatilization rate regulator, suitably is used.

In the present invention, the material of the absorbent core 5 may be any material, whether organic or inorganic, and specific examples thereof include the following. For example, felt core,
Inorganic fibers such as unfired core, asbestos core, porcelain porous, glass fiber, asbestos, etc. hardened with a binder such as gypsum or bentonite, glass powder, kaolin, activated clay, talc, diatomaceous earth, clay, perlite, bentonite ,
Alumina, silica, alumina silica, titanium, one or more mineral powders such as calcined powder of vitreous volcanic rock and calcined powder of vitreous volcanic ash, or a mixture of these powders with wood powder, charcoal powder, activated carbon, etc. Dextrin, starch, silicone resin, fluororesin, arabic gum, carboxymethylcellulose, solidified with a binder such as synthetic glue, and the like.

Particularly preferred liquid absorbent cores 5 include 100 parts by weight of the above-mentioned mineral substance powder and wood flour or a mixture of wood flour and a mixture of carbon powder and / or activated carbon up to an equal weight of 10 to 3 parts
And 5 to 25 parts by weight of the total absorbent core weight.
Examples thereof include those produced by blending parts by weight of the binder, further adding water thereto, kneading, extruding, and drying. This liquid absorbing core 5 has a liquid absorbing speed of 1
It is desirably from 40 to 40 hours, preferably from 8 to 21 hours. Such a liquid absorption rate means that a liquid absorbent core having a diameter of 7 mm and a length of 70 mm is immersed in an n-paraffin liquid at a liquid temperature of 25 ° C. to a depth of 15 mm from the lower part, and n-paraffin is placed on the top of the liquid absorbent core. It means the value determined by measuring the time to reach. The liquid absorbent core 5 may further contain a coloring agent such as malachite green, sorbic acid and salts thereof, and a fungicide such as dehydroacetic acid, if necessary.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a heat-transpiration insecticidal method according to the present invention.

FIG. 1 and FIG. 2 show an embodiment of the method of the present invention. 1 is a heated transpiration insecticidal solution for the absorbent core 2
Is a container body of a heated and evaporating body, and the mouth 1 a of the container body 1 is closed by a closing body 3. A projecting portion 1b is provided on the bottom of the container body 1, and the width adjusting member 4 and the height adjusting member 7 are combined and mounted on the projecting portion 1b. Further, a cylindrical portion 6 into which the columnar liquid absorbing core 5 is inserted is provided vertically on the closing body 3. In this manner, the heated transpiration insecticidal solution 2 for the liquid absorbent core contained in the container body 1 is sucked up by the liquid absorbent core 5 provided in the container body 1 and the upper part of the liquid absorbent core 5 is heated by a heater 10 described later.
