Abstract

PURPOSE:To provide an insecticidal device handleable easily and capable of preventing hazards of fire and emission of odor, and composed of a catalyst impregnated with a mixture of a liquid fuel and an insecticide, and a heater device containing a dry cell for the catalytic combustion of the mixed liquid in the catalyst. CONSTITUTION:An impregnating material 8 made of glass wool is put into the bottom part of a vessel 1 and impregnated uniformly with a mixture of a fuel (e.g. benzine, kerosine, etc.) and an insecticide (e.g. allethrin, phthalthrin, etc.) through the injection pipe 6 having a nozzle 6a. A catalyst A made of platinum wool is placed in contact with the top of the impregnating material 8. The catalyst A is heated with the heating device B composed of the switch 15, the lead wire 14, the fixing tool 13, the heater-holding arm 12 made of Ni, and the heater 11 made of platinum-rhodium, to effect the stable catalytic combustion of the insecticide liquid and dissipate the active component through the insecticidal component dissipation port 5 opened to the lid 4 of the vessel 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an insecticide used for killing insects such as mosquitoes.

Conventional technology> Conventionally, insecticides for mosquito repellents place an insecticidal mat on top of a constant-temperature heating element, and use a type i that evaporates the insecticidal components of the mat.
be. In this case, it is necessary to heat the heating element' with electricity or fuel such as methyl alcohol.

In other words, it is inconvenient because it requires two items, one for killing insects and one for heating the heating element. In particular, devices that require electricity are inconvenient because they cannot be used outdoors in most cases.

In addition, there is a type of insecticide for mosquitoes and insecticides that uses a thermostatic heating element to heat the insecticidal liquid and volatilize the insecticidal ingredients. In this case, it is inconvenient because it cannot be used outdoors in most cases.

Further, although conventional mosquito repellent incense does not require electricity or fuel, there is a risk of fire and a strong odor.

<Purpose> The present invention was made in order to eliminate the drawbacks of the conventional
The object of the present invention is to provide an insecticide that does not require separate electricity or fuel, is easy to handle, and can prevent fires and odor.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. The insecticide according to the present invention includes a catalyst body A impregnated with a liquid mixture of liquid fuel and an insecticide. , and a heater device B for catalytically combusting the liquid mixture in the catalyst body A.

FIG. 1 is a perspective view of the insecticide, which consists of a container 1 and a battery case 2. The battery case 2 has a space for storing one single battery. The container 1 has a combustion air intake port 3 formed on its side surface, and an insecticidal component volatilization port 5 formed in the container lid 4.

In addition, on the side of the container 1, there is an injection vibrator for injecting a mixture of primary petroleum (benzine, etc.) or secondary petroleum H (kerosene, etc.) fuel and insecticide or insecticidal liquid (allethrin, 7-talsulin, etc.). is provided. FIG. 2 is a structural sectional view of the container of the insecticide. The injection vibro is provided with an injection lob tuff on its outer end that can be opened and closed, and the inner end of the injection vibro extends into a glass wool immersion body 8 housed in the lower part of the container 1. A large number of pores 6a are formed so that the liquid mixture permeates the entire infiltrating body 8 uniformly.

Then, the platinum cotton catalyst A is placed in contact with the upper surface of the infiltrator 8. This catalyst body A is made by uniformly mixing platinum asbestos, palladium asbestos, etc. with asbestos and plascool, adding a binder material, and molding the mixture. The catalyst body A is fixed to the volume H1 via a fixing rod 10. Catalyst A is for stable catalytic combustion and volatilization of the active ingredient of the insecticidal liquid, and is set to a size that will not be blown off by slight impact or wind.

Further, as shown in Fig. 2.3.4, the heater device B includes a platinum-rhodium heater 11 that is close to the top surface of the catalyst body A, a nickel heater support rod 12 that supports the heater, and a nickel heater support rod 12 that supports the heater. A fixture 13 fixed to the container 1, a lead wire 14 for supplying power to the support rod 12, and a switch 15 electrically connected to the outer end of the lead wire and fixed to the outer wall of the container 1. configured. And the electric circuit C
As shown in FIG. 4, a switch 15, a heater 11, and a power source D (dry battery) are connected in series. Note that 16 is a lead wire that connects the switch 15 and the power source of the case 2.

In the above configuration, the liquid mixture is injected into the infiltrator 8 from the injection vibro, and penetrates into the catalyst body A in contact with the infiltrator 8 by capillary action, volatilization, and the like. Here, the heater 11 is heated by turning on the switch 15 for 5 to 10 seconds until catalytic combustion by the catalyst body A starts. Then, like the catalyst body A, the heater 11 catalytically burns the mixed liquid. The nature of catalytic combustion is that it does not get too hot and burns little by little, so the mixed liquid gradually catalytically burns and can be used for a long time with a small amount of liquid.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

Effect> As is clear from the above description, the present invention is provided with a catalyst body impregnated with a liquid mixture of liquid fuel and an insecticide, and a heater device for burning the mixture inside the catalyst body. This invention relates to an insecticide characterized by:
