Abstract

PURPOSE:To vaporize a chemical agent such as insecticide by taking advantage of chemical exothermic reaction. CONSTITUTION:An exothermic material 2 such as iron powder is blended with pieces 3 of a chemical agent, small pieces impregnated with a chemical agent such as insecticide and packed into a bag material 1 made of an air-permeable material to give a chemical agent vaporizing material 4. The chemical agent vaporizing material 4 is always put in a sealing material sealed with an inert gas. When the chemical agent vaporizing material is used, the sealing material is removed. Consequently, air is sent into the bag material 1 and oxidative exothermic reaction with the exothermic material 2 occurs. The pieces 3 of the chemical agent are heated by the heat, the impregnated chemical agent is vaporized and flows into air. When the pieces of the chemical agent, for example, are pieces of an insecticide, a gas of the insecticide exterminates mosquitoes and the chemical agent vaporizing material 4 is used for destroying mosquitoes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chemical vaporizer for vaporizing a chemical such as an insecticide by heat generated by a heat generating material, and more particularly to a chemical vaporizer suitable for insecticide.

[0002]

2. Description of the Related Art As one of insecticides, a mosquito coil has been used for exterminating mosquitoes. Since the effect of mosquito coil is long-lasting once ignited, it is widely used in place of or in combination with spray insecticides. However, the mosquito coil has a potential danger such that a fire may occur and an infant or the like may be burned because it continues to be ignited during use. For this reason, the so-called electric mosquito repellent, which electrically heats a mat impregnated with an insecticide, has been widely used recently, and instead of a disposable mat, a liquid insecticide filled in a tank is gradually vaporized. So-called liquid mosquito traps have also come into use.

[0003]

The above-mentioned electric mosquito repellent or liquid mosquito repellent, which is a modification of the above-mentioned electric mosquito repellent, has almost no fear of fire or burn, and its insecticidal power is equal to or higher than that of conventional mosquito coil, and at present, The sales amount excludes the mosquito coil. However, this electric mosquito repellent (hereinafter, this term is also used as a word including electric liquid mosquito repellent) has the following problems and mechanical restrictions.

First of all, the electric mosquito repels electricity as its name suggests. More specifically, a 100 V AC power source for home use is used to heat a heating element, and the heat is used to impregnate the mat. It is configured to vaporize some insecticides or vaporize liquid insecticides. For this reason, the use of the mosquito repellent device is naturally limited to the place with the power source,
It is practically impossible to use it outdoors. In addition, even if it is indoors, its installation location is restricted by the length of the power cord, and further inconvenience arises such as getting caught in the power cord.

DISCLOSURE OF THE INVENTION The present invention is configured to solve the above-mentioned problems, and includes an exothermic material that generates heat by an exothermic reaction such as an oxidation reaction of iron-based powder, an insecticide, and the like. Is a chemical vaporization material comprising a large number of small pieces containing the chemical to be vaporized.

[0006]

[Function] The heat generating material generates heat due to an exothermic reaction such as an oxidation reaction caused by oxygen in the air. On the other hand, the small piece containing the drug to be vaporized is heated by the heat of the heat-generating material by being mixed with or placed close to the heat-generating material, and the drug is vaporized. For example, when the contained drug is an insecticide, the gas of the insecticide controls the target insects.

In use, the pack is first removed, whereby the chemical vaporizer 4 is exposed to the air,
The exothermic material 2 in the bag material 1 generates heat by causing an oxidation reaction with oxygen in the air flowing into the bag material 1 through the bag material 1. As a result, the drug piece 3 mixed with the exothermic material 2 is also heated,
This heat vaporizes the insecticide impregnated in the medicine piece 3. The vaporized gas passes through the mixture consisting of the exothermic material 2 and the other drug piece 3, and also passes through the bag material 1 and flows out into the air, and the mosquitoes around the mosquito are exterminated by the outflowing insecticide gas. Although not shown, a suspending portion is provided for the chemical vaporization material 4 so that the chemical vaporization material 4 can be suspended at an arbitrary place by using this suspending tool.

First, the heat generating material 2 described above is filled in the bag material 5 inside. The upper and lower sides of the bag material 5 are filled with the drug pieces 3, respectively, and the bag material 5 filled with the heat-generating material 2 is sandwiched between the layers of the upper and lower drug pieces 3.

In this embodiment, when the chemical vaporization material 4 is exposed to the air, the air mainly contacts the exothermic material 2 in the bag material 5 through the layers of the upper and lower chemical pieces 3 and the exothermic material 2 undergoes an oxidation reaction. Occurs and heat generation starts. As a result, the upper and lower medicine pieces 3 are heated, and the insecticide impregnated in the medicine pieces 3 is filled with the bag material 1.
The mosquito is exterminated by flowing out into the air through.

4 and 5 show a fourth embodiment. 6
Is a container and is made of plastic or other similar material. Inside the container 6, as shown in FIG.
And a drug piece 3 are filled. One surface of the container 6 becomes an open portion 6a, and a nonwoven fabric is provided in the open portion 6a.
Alternatively, a breathable ventilation material 7 made of a woven cloth or the like is developed so as to define the inside and outside of the container. Further, a sealing material 8 having airtightness is attached so as to completely cover the container opening portion 6a where the ventilating material 7 is developed, whereby the mixture of the exothermic material 2 and the drug piece 3 inside the container is inside the container 6 It is airtightly sealed.

In use, the sealing material 8 is peeled off and the container is placed at an arbitrary place. By removing the sealing material 8, oxygen in the air passes through the ventilation material 7 and permeates into the inside of the container to react with the heat generating material 2. The chemical piece 3 is heated by the heat generated by this reaction, and the vaporized insecticide passes through the ventilation material 7 and flows out into the air.

In this embodiment, the entire chemical vaporization material is constructed as a single container, so that a predetermined purpose such as insecticidal can be achieved simply by placing this container at an arbitrary place.

6 and 7 show a fifth embodiment. 9
Is a cylindrical container made of plastic or the same material as that of the above-mentioned embodiment. Figure 7
(A) and (B) are the heat generating material 2 and the drug piece 3 in the container 9.
The filling state of is shown. First, the heat generating material 2 is shown in (A).
And the drug piece 3 are mixed and filled in the same manner as in the case of the fourth embodiment, and the ventilation member 10 similar to the ventilation member 7 is spread in the upper open portion 9a of the container 9, and A sealing material 11 similar to the sealing material 8 is attached so as to seal the open portion 9a.

Next, in the structure shown in FIG. 7B, the heat generating material 2 is filled in the bottom side of the container 9, and the upper part of the filling layer of the heat generating material 2 is made of a gas permeable material having the same effect as the gas permeable material 10. The drug pieces 3 are filled in layers through the ventilation member 10a, and the ventilation member 10 is attached to the container upper opening 9a. Further, the sealing member 11 is provided so as to completely cover the upper opening 9a.

In the configuration shown in FIG. 7B, the side opening 9b is formed in at least a part of the circumferential direction of the side wall of the container corresponding to the filling layer of the heat-generating material 2, and A ventilation material 10b is attached to the side opening portion 9b. Further, a seal material 11a is attached to a portion where the side open portion 9b is formed so as to completely seal the open portion 9b.

When the seal material 11 is peeled off in use, oxygen in the air passes through the ventilation material 10 and permeates into the inside of the container to react with the heat generating material 2, as in the case of the fourth embodiment. The chemical pieces 3 are heated by the heat generated by this reaction, and the vaporized insecticide passes through the ventilation material 10 and flows out into the air. In this case, especially in the configuration shown in FIG.
Since the side opening 9b is formed, by removing the sealing material 11a covering the opening 9b, the air directly contacts the layer of the heat generating material 2 through the side opening 9b,
A more effective exothermic reaction occurs, and this heat heats the upper layer of the drug piece 3 to vaporize the insecticide. In the configuration shown in FIG. 7B, the side opening 9b is provided so that the air and the vaporized insecticide flow as shown by the arrow by providing the side opening 9b.
Since it is continuous from the upper part to the upper open part 9a, it becomes possible to efficiently vaporize the pesticide and discharge the vaporized gas. It should be noted that it is possible to form the side opening portion as well as the structure shown in FIG. 7 (A).

Although the embodiments of the present invention have been described by taking the case of vaporizing the insecticide as an example, it goes without saying that the agent to be vaporized may be other than the insecticide.
