Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pest control apparatus that volatilizes a drug with an ultrasonic oscillator and diffuses an active ingredient in the room, and also enables downsizing of the body.
[0002]
[Prior art]
Conventionally, as a method for evaporating the insecticide solution for insects, the insecticide solution is sucked up and heated using a liquid absorbent core, or the insecticide adsorbed on a porous substrate (solid mat) such as a fiberboard is heated. There are known a method of volatilizing an insecticide and a method of volatilizing an insecticide by wind power generated by rotation of a fan. However, the heating transpiration method has a problem that an insecticide that is easily pyrolyzed cannot be used because the heating temperature is high, and the volatilization method using wind power has a problem that an insecticide having a low vapor pressure is difficult to volatilize.
[0003]
On the other hand, a method has been proposed in which an insecticide containing an insecticide is atomized by an ultrasonic oscillator and volatilized in the air (see Patent Document 1 and Patent Document 2). The insecticide is used in the form of an emulsion obtained by dissolving or dispersing an oil-soluble insecticide in an organic solvent such as kerosene, or using water as a solvent and emulsifying the insecticide. In addition, an ultrasonic liquid evaporation apparatus that evaporates insecticides and fragrances using ultrasonic waves has been proposed (see Patent Document 3).

[Problems to be solved by the invention]
However, in the pest control apparatus using the ultrasonic oscillator as described above, since the emphasis was placed on making the fog state visible, it was not sufficiently satisfactory for use as a pest control apparatus. . In particular, in order to diffuse the drug efficiently into the room, it is necessary to volatilize the drug with an ultrasonic oscillator and make the active ingredient present at a moderately high location in the room. For example, if the volatilized chemical is present at a moderately high location in the room, the insecticidal efficacy is enhanced. However, in a pest control apparatus using a conventional ultrasonic oscillator, the diffusibility is poor, so that the drug cannot be present in a high place in the room.
[0006]
Accordingly, a main object of the present invention is to provide a pest control apparatus that can volatilize a drug with an ultrasonic oscillator and diffuse an active ingredient over a wide range in a room.
Another object of the present invention is to provide a pest control apparatus capable of downsizing the body.
[0007]
[Means for Solving the Problems]
  As a result of intensive studies to solve the above-mentioned problems, the present inventors have made the drug atomized in the container and created a flow path for the diffusion air so that the drug is not prevented from diffusing in the container. And an ultrasonic oscillator in the air flow path of the body.TheHeat source that generates heat when energizedAsWhen installed, the heat generated by energizing the ultrasonic oscillator can be used, so the atomized medicine is diffused outside the body in the air stream, so that the active ingredient is diffused widely in the room. The present inventors have found a new fact that it is possible to complete the present invention.

[0013]
DETAILED DESCRIPTION OF THE INVENTION
<First Embodiment>
FIG. 1 is a schematic sectional view showing a first embodiment of a pest control apparatus according to the present invention. In this pest control apparatus, as shown in FIG. 1, a container 5 in which a pest control liquid 4 is placed is installed in a cylindrical container 1 having upper and lower vents 2 and 3. An ultrasonic oscillator 6 is attached to the bottom of the container 5. The ultrasonic oscillator 6 has a vibrator in contact with the bottom of the container 5 and atomizes the insect pest control liquid 4 in the container 5 with the vibration of the vibrator. The vents 2 and 3 may be closed with a mesh-like vent plate such as a net or a perforated plate.
[0014]
A diffusion fan 7 is installed below the container 5. By driving this fan 7, the flow of air that enters the vent 2 and rises inside the container 1 and is exhausted from the vent 3. A path is formed (the direction of air flow is indicated by arrow A). By securing such a flow path, the capacity of the fan can be minimized. That is, the diffusion fan 7 is a fan that can secure an air volume necessary for diffusing the active ingredient. For example, the air volume is 0.1 to 10 L / sec in a 6 tatami space, and actually about 0.1 to 1.5 L / sec. If it is. Floor area 40m²The air volume of about 4L / sec is sufficient even in restaurants.
[0015]
The ultrasonic oscillator 6 in the present invention refers to a device that generates ultrasonic waves using, for example, a piezoelectric effect or a magnetostrictive effect. Then, in order to vibrate the portion of the container 5 in contact with the pest control solution 4, one surface or part of the container is a deformable sheet or thin plate, a microporous thin plate or film, or a part of the container is It is good to be composed of rubber or spring plate.
[0016]
  here, Body 1IsIn addition to the ultrasonic oscillator circuit, the ultrasonic oscillator itself, connection lines, connection terminals, etc. have a configuration that can effectively use heat generated by energization. ThereforeThe fan may be omitted because an updraft flowing through the body 1 is generated by the heat. In this case, there is an advantage that the apparatus can be miniaturized.
[0017]
The fine particles of the medicine atomized from the container 5 by the ultrasonic waves are discharged from the upper vent 3 of the container body 1 by the air flow path in the container body 1 and carried upward in the room, and then the active ingredient is widely spread in the room. Spread. For this reason, compared with the conventional ultrasonic atomizer, insecticidal efficacy can be improved dramatically.
[0018]
Here, as for the particle diameter of the atomized medicine, the center particle diameter (alias: average particle diameter, Sauter average diameter or body area average diameter) is preferably about 3 to 8 μm. The particle diameter can be arbitrarily adjusted by changing the frequency of the ultrasonic oscillator 6. The frequency of the ultrasonic oscillator 6 is not limited as much as possible, but is adjusted to 1 to 3 MHz, preferably about 1.5 to 2.5 MHz, and the output is adjusted to 1 to 80 W, preferably about 1 to 60 W. Is good. When a water-soluble pest control agent described later is used, the frequency of the water used as the solvent is in the range of 50 to 160 Hz. That is, since the vibration frequency of the ultrasonic oscillator is 1 to 3 MHz and the vibration frequency of water is 50 to 160 Hz, a combination of the former high frequency and the latter low frequency is given as an example. Of course, the present invention is not limited to this combination as long as practicable.
[0019]
A rotating plug 8 for energizing a drive source (not shown) of the ultrasonic oscillator 6 and the fan 7 is attached to the body 1. As shown in FIG. 1, the rotary plug 8 is rotatably attached to the container body 1 through the lower vent 2. For this reason, as shown by the solid line in the figure, when the rotary plug 8 is rotated from the inside of the container 1 to the horizontal position (that is, when it is rotated by 180 °), an outlet provided on the wall surface (not shown). 2), the container 1 is held on the wall surface, and at the same time, the ultrasonic oscillator 6 and the drive source of the fan 7 can be energized.
[0020]
Further, when the rotating plug 8 is rotated from the inside of the body 1 to a vertical posture (that is, rotated 90 °), the plug 8 is inserted into a table tap installed on a floor surface or a desk to hold the body 1. In addition, it is possible to energize the drive sources of the ultrasonic oscillator 6 and the fan 7. And when not in use, the rotary plug 8 may be rotated and stored in the container 1. For this reason, the pest control apparatus according to this embodiment can be easily carried and used.
[0021]
Examples of the pest control solution 4 include a pest control agent aqueous solution in which a water-soluble pest control agent is dissolved in water. The water-soluble pest control agent is not particularly limited as long as it has an insecticidal or repellent action against pests and is liquid-soluble, and preferably has a vapor pressure of 1 × 10.^-3~ 1x10^-9mmHg, more preferably 1 × 10^-Five~ 1x10^-8It should be mmHg. Examples of such pest control agents include 1-methyl-2-nitro-3-[(3-tetrahydrofuryl) methyl] guanidine, N- [chloro-3-pyridylmethyl] -N-ethyl-N-methyl-2-nitrovinylidenediamine. , 3-[(2-chloro-5-thiazolyl) methyl] -5-methyl-nitroiminotetrahydro-1,3,5-oxadiazine ”and the like.
