Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a method for killing pests such as mites that are parasitic or attached to flooring materials such as floorboards, tatami mats, carpets, vinyl tiles, and cork. be.

(Prior Art) Conventionally, these insecticides have been carried out exclusively by sprinkling chemicals on the flooring material or by heat treating the flooring material.

(Problems to be Solved by the Invention) When using the above chemical, it is difficult to determine the appropriate amount for killing insects; if it is too little, the pests will not die, and if it is too much, the chemical will remain on the floor and be harmful to the human body. Furthermore, in the case of heat treatment, raising the temperature or taking a long time to increase the effect can cause deterioration of the quality of the flooring material, especially the fibers.
Therefore, it has been difficult to completely kill insects.

(Means for Solving the Problems) Therefore, the present invention has proposed that the adhesion of insect pests such as mites to flooring materials such as carpets has an adhesive force of 80% due to electrostatic force.
%, we first removed the static electricity from the flooring material, removed the force of adhesion of pests attached to the flooring material due to this static electricity, and then placed the vibrating heat radiator on this flooring material. Insects are heated and killed by floating them on the surface of the carpet and bringing them into contact with or close to the heated vibrating heat radiator. In addition to this method, a ceramic layer may be provided on the lower surface of the vibrating heat sink, and far-infrared rays with good transparency may be irradiated. Ideally, this far infrared ray should have a long wavelength of around 1 to 15 microns.

Next, the method of this invention will be explained.

A solution of an antistatic agent is put into a solution tank (not shown), and the solution is injected into the solution pipe 14 of the vibrating heat radiator 10 through the liquid pipe 16 using a pump (not shown) or the like.
When the motor 2 is operated, the eccentric cam 6 rotates, vibrates the diaphragm support 4, and the diaphragm 8 and vibration heat sink 10, which are integral with the diaphragm 8, vibrate. As a result, the antistatic agent solution in the solution pipe 14 comes out little by little from the liquid spout 15 to the lower surface of the vibrating heat radiator 10 .
In this state, hold the handle 21 with your hand and
Press , place the object to be coated on the tarp to remove pests, and apply while moving it on the desired floor surface. At this time, the solution is forced and spread by the vibration of the pressing surface of the vibrating heat radiator, spreads thinly to every corner of the carpet, and penetrates to the root of the hair. Moreover, by turning on the heating wire 13 in the vibrating heat radiator 10, the vibrating heat radiator 10 is heated, and the solution on the carpet in contact with or in the vicinity of the vibrating heat radiator 10 is dried. Furthermore, far infrared rays are emitted from the lower ceramic layer 10a of the vibrating heat radiator 10 and dry the solution that has penetrated to the root of the carpet's hair. The solution applied in this manner dries to form a coating consisting of an antistatic agent, and the static electricity is removed from the carpet. As a result, the mites that were attached to the roots of the hair of the carpet lose most of their adhesion. Subsequently, by applying vibrations to the vibrating heat radiator 10, the mites present between the hairs of the carpet float to the top of the hairs of the bed due to the whirling motion.
When the mites come close to or come into contact with the vibrating heat radiator 10, they are killed by the heat. At this time, mites can also be killed by the heat of evaporation during evaporation of the solvent in the antistatic agent solution.

Then, the dead mites appearing on the surface of the carpet are removed by sucking them up with a vacuum cleaner or by other appropriate methods. At this time, as shown in FIG.
A vacuum suction device 23 having a vacuum suction device 23 may be provided to suck up dead mite carcasses.

In addition, the antistatic agent solution in the above example is mainly water, but a solution containing a few percent of ethyl alcohol not only speeds up the drying speed, but also takes into account the sterilizing power of the ethyl alcohol, so it can be used to remove other dust. It also affects bacteria such as shape, and is highly effective as an insecticide and sterilizer. Of course, it is also possible to supplement the insecticidal and sterilizing effects by adding a small amount of a bactericide, insecticide, etc. to the antistatic agent solution.

Ideally, the heat of the vibrating heat radiator is within 60°C to 150°C, and within this range will not damage flooring materials made of fibers. In addition, in the above coating and insecticidal apparatus, the driving source of the vibrating heat radiator is the motor 2, but this vibration source is not limited to this, and may be any suitable source such as an electromagnetic type, an ultrasonic vibration type, etc., and the vibration frequency may be Ten
Applicable from Hz to around 10MHz in the ultrasonic range.

Further, in the above embodiment, the ceramic layer 10a is provided on the lower surface of the vibrating heat sink 10, but if far infrared rays are not required, the ceramic layer 10a is not limited to this, and resin processing such as Teflon, metal plating processing, etc. may be applied. Further, in the above embodiment, the heat source of the vibrating heat radiator is a heater, but the present invention is not limited to this, and any suitable heat source may be used.

Further, in the above embodiment, static electricity was removed by applying an antistatic agent, but the removal of static electricity from the floor material is not limited to this.For example, as shown in FIG.
It is also possible to use other suitable methods, such as forming a ring into a ring and installing a device 24 for corona discharge, ultraviolet irradiation, radiation irradiation, ion wind irradiation, etc. in this hollow part to remove static electricity. .

(Effects of the Invention) The present invention has the above-described configuration, and removes static electricity from the flooring material in which pests are infested, reduces the adhesion of the pests to the flooring material, and heats and kills the pests. Therefore, unlike conventional methods that use drugs, there is no adverse effect on the human body and it is safe. In addition, pests whose adhesion has weakened are forcibly lifted to the surface of the flooring material by vibration, brought close to the vibrating heat radiator, and heated to kill the pests, making it possible to treat them extremely quickly. Furthermore, since the vibrating heat radiator comes into contact with the surface of the floor material intermittently due to vibration, it is sufficient to heat only the surface layer of the floor material, and the floor material itself is not damaged, and in particular, fibers etc. are not altered. Therefore, it can also be used to kill insects on heat-sensitive flooring materials.

Furthermore, vibrating heat radiators with a ceramic layer on the bottom surface emit far-infrared rays, and because these far-infrared rays have good penetration, the heat reaches the inside of flooring materials such as carpets, killing pests attached to those areas. It can be killed, and the temperature can be around 60℃, so it will not damage flooring materials.
