DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reaction which takes place when a liquid agent such as an insecticide such as a flying insect, a bactericide, a disinfectant or an aromatic is brought into contact with a volatile fuel such as alcohol and a catalyst in the air. The present invention relates to a portable chemical evaporator that uses heat to evaporate continuously for a long time even in a place where there is no power supply.

[0002]

2. Description of the Related Art In order to evaporate insecticides for flying insects over a long period of time, a mat containing a required insecticidally active ingredient is impregnated in advance into a mat, and the insecticide mat is heated by an electric heater to remove the insecticidally active ingredient. There is a so-called electric mosquito trap that volatilizes. Further, in the method of heating and volatilizing the insecticidal mat, it is difficult to volatilize the active ingredient uniformly over a long period of time, and furthermore, the transpiration time is limited to 8 to 10 hours, and further continuous transpiration is difficult. For this reason, the mats that have been impregnated with the insecticide in advance are improved, and the liquid insecticide in the bottle is heated by an electric heater utilizing the capillary phenomenon, and the active ingredient is uniformly evaporated over a period of about one month or more. The method of making it practical has been put to practical use. In the case where an electric heater is used as the heater, the location where the electric power is used is supplied with commercial power or is limited to a range where the commercial power can be supplied with a power cord. In order to improve this and enable use in places where commercial power cannot be supplied, a volatile fuel such as alcohol is used as a heating source, and the reaction that occurs when this fuel is catalyzed in the air with a catalyst such as platinum or palladium. Various systems have been proposed in which a metal radiator plate is heated using heat and an insecticidal mat is placed on the radiator plate to evaporate.

[0003]

Therefore, when a volatile fuel is used as a heating source by reacting it with air using a catalyst, the insecticide can be volatilized for a long time until the fuel is consumed without a commercial power supply. There are advantages. However, in the conventional method using a volatile fuel and a catalyst, the heat radiating plate is heated by the heat generated by the catalyst due to its structure, and the insecticide is heated and evaporated by this. Cannot be used directly, but instead uses an insecticidal mat impregnated with it, and the transpiration time of the insecticidal active ingredient is limited to about 8 to 10 hours.

It is an object of the present invention to provide a method for uniformly using a pesticide over a long period of time, as well as a method of heating a liquid pesticide by an electric heater, and to easily use the pesticide even in a place where a commercial power source is not available.

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and comprises a liquid medicine container having a liquid absorbing core, and a portable liquid container for evaporating the liquid chemical by heating the upper part of the liquid absorbing core. In a chemical liquid evaporator, a container filled with a volatile fuel and a certain space provided above the container, a catalyst for fuel oxidation is arranged in the evaporator main body, and an air inlet is provided in a part of the evaporator. The gist of the invention is that the relative position between the catalyst and the upper portion of the liquid absorbent core is set so that the upper portion of the liquid absorbent core is heated by the catalyst to evaporate the drug.

[0006]

[Operation] The evaporator main body equipped with a fuel oxidation catalyst is equipped with a fuel container filled with volatile fuel and a chemical solution container filled with a liquid chemical and having a liquid absorbing core.

In the figure, reference numeral 1 denotes an evaporator main body for heating and evaporating a liquid chemical such as an insecticide. The evaporator main body 1 has a required shape and size.
Either the lid 2 or the bottom 3 is detachable from the main body 1, whereby the vaporizer main body 1 accommodates the chemical liquid container 4 filled with the liquid chemical and the fuel 5.

In the illustrated embodiment, the bottom 3 is detachable from the evaporator main body 1, the lid 2 is integrated with the main body 1, a chemical solution container 4 is provided at the center inside the bottom 3, and a fuel 5 is provided at the outer periphery thereof. The evaporator body 1 may be exchangeable and can be stored, and may be fixed at a predetermined position inside the bottom as needed when carrying the evaporator body 1 so as not to move unnecessarily. When the bottom 3 is detachable as described above, the lid 2 is attached to the main body 1.
And one. Conversely, the bottom 3 may be integrated with the main body 1 and the lid 2 may be detachable.

A ring-shaped catalyst 6 is attached to the lid 2, and a predetermined gap C is formed between the inner peripheral surface of the catalyst 6 and a through hole provided in the center of the catalyst 6 as shown in FIGS. And the absorbent core 7 is inserted. The gap C is heated by the thermal energy generated when the catalyst reacts with the fuel and air, and the chemical solution in the chemical solution container sucked up by the capillary phenomenon by the liquid absorbing core 7 evaporates without damaging the pesticidal active ingredient. It is determined so that the necessary heating is performed.

As the catalyst, metals such as platinum and palladium,
Using a ceramic or the like, the catalyst is heated by an electric heater 8 such as a filament heater or a ceramic heater close to the catalyst 6 to enable the fuel to be ignited by the catalyst, and a part of the evaporator body, for example, as shown in the figure. Air is taken into the inside R of the evaporator body 1 from the air inlet H perforated on the outer peripheral wall, the bottom, etc., and the gap C between the catalyst 6 and the catalyst and the liquid absorbing core is formed.
The air is circulated to the upper part of the main body through. At this time,
The upper outer peripheral surface of the absorbent core is heated by the catalyst, and the gaseous substance of the drug to be evaporated evaporates through the outer peripheral portion through the inside of the catalyst and is surrounded by the heated air layer. Is released and diffused outside the main body.

As the fuel stored in the main body, a volatile gelled fuel or a liquefied gas such as butane can be used in addition to the alcoholic volatile solid fuel. When this liquefied gas is used, the pressure is reduced when filling the container under pressure and discharging from the container, and the amount of discharge is adjusted by a valve to guide the vaporized gas to the catalyst.

In the second embodiment shown in FIGS. 3 and 4, the upper end of the liquid absorbent core 7 or a part thereof is in contact with or close to the honeycomb formed catalyst 61, and the catalyst 61 is exposed to direct heat or radiant heat. This is to evaporate the chemical. In this case, the catalyst 61 is supported by the lid 2 in a shape such as a flat disk or a square shape even if it is not a ring shape. FIG.
In this embodiment, the upper end of the absorbent core 7 is as close as possible to the lower surface of the catalyst.

The liquid medicine container 4 is filled with a desired liquid insecticide or other chemicals, and the liquid absorbent core 7 is inserted so as to reach almost the bottom of the container, and the upper end of the liquid absorbent core 7 protrudes from the container. Then, the protruding core end is heated by the catalyst. The material of the liquid absorbing core 7 is not limited to a felt shape, a woven string shape, a ceramic material, etc., as long as it sucks up a liquid medicine by a capillary phenomenon. The second embodiment differs from the first embodiment only in the method of installing the liquid-absorbing wick for the catalyst, and the operation and effects are the same as those of the first embodiment. Further, in any of the embodiments, a rectifying hood 10 of an inverted funnel type is provided in the main body 1 so that the air and fuel vaporized gas introduced into the main body R from the air inlet H are surely and smoothly directed toward the catalyst. It may be distributed.

In the first and second embodiments, the fuel and the chemical liquid container are stored in the evaporator main body 1. However, the evaporator main body 1 is provided with a gas cylinder used for a disposable gas lighter or the like. Alternatively, the fuel cylinder and the chemical solution container 4 may be provided detachably. In such a detachable embodiment, a catalyst is provided in the evaporator main body 1 in the same manner as in the first and second embodiments, and the chemical solution container 4 is set at a predetermined position in the main body 1 so as to be close to the catalyst. Alternatively, the gas volatilized by inserting and setting the cassette type fuel is guided to the catalyst.

Further, when a liquefied gas is used as a fuel,
The gas emitted from the gas cylinder is ignited and heated by a piezoelectric element or the like, and the reaction proceeds to the reaction of the catalyst, so that the drug sucked up by the absorbent core is volatilized by heating.

In the embodiment shown in FIG. 5, the fuel 15 and the chemical 14 are added to the evaporator main body 1 provided with the catalyst in one container 11.
The container which is divided and filled in the container is detachably connected by a cassette or the like by screwing or other methods. For example, the medicine 14 is filled in the central chamber of the container and the fuel 15 is filled in the outer peripheral chamber. When the filling chamber and the fuel filling chamber are adjacently provided side by side and integrated, and this is mounted on the main body 1, the fuel is guided to the catalyst and burns, and the drug absorbs the wick close to the catalyst or passes through the inside. In this way, the relative positional relationship between the main body 1 and the cassette type container 11 is determined in advance.

[0017]

The portable chemical evaporator of the present invention can evaporate active ingredients for a long time by using a liquid medicine even in a region where commercial power cannot be supplied, and has an advantage that it is convenient to carry. . Further, since the straightening hood is provided in the evaporator main body, there is an advantage that the air introduced into the main body and the gaseous substance of the volatilized fuel are surely guided to the catalyst. Since the liquid-absorbing core penetrates through the inside of the ring-shaped catalyst, evaporation of the chemical solution is ensured. Since the liquid medicine container and the fuel container can be attached to and detached from the evaporator body in a cassette type, the supply of the medicine and the fuel can be easily performed. Furthermore, when the catalyst has a honeycomb structure, the volatilized gas and the air taken in from the outside are mixed at a fixed ratio, and the heat reacted by the catalyst is accumulated in the honeycomb, resulting in an ascending airflow, which has the advantage of further increasing the volatilization efficiency. .
