Description

[Detailed description of the invention] Industrial application field The present invention is a transpiration device, in particular, a transpiration device that combines an outer container and an inner container, in which a hydrothermal exothermic agent is placed in the outer container and the heat generated by the exothermic agent is stored in the inner container. The present invention relates to a transpiration device containing a transpiration agent that is heated in a transpiration chamber.

Since such a transpiration device is assembled with the inner container built into the outer container, the peripheral wall and bottom of the inner container are surrounded by the hydrothermal exothermic agent in the outer container, and the peripheral wall and bottom serve as a heat-receiving surface. Therefore, the transpiration agent in the inner container is efficiently heated by the heat generated by the exothermic agent in the outer container.

However, in this type of transpiration device, it is usually necessary to seal the top opening of the inner container in order to prevent the transpiration agent in the inner container from spilling during handling before use, such as during transportation of the transpiration device. Therefore, when using this type of evaporator, in order to evaporate the transpiration agent in the inner container, the seal at the top opening of the inner container must be broken, and the seal cannot be opened easily. As a result, the above-mentioned usefulness is diminished.

BACKGROUND TECHNOLOGY AND PROBLEMS However, in the conventionally known evaporators of the above type, there is no guarantee that the seal at the top opening of the inner container can be easily opened.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a transpiration device of the type described above, which ensures that the seal at the top opening of the inner container can be easily opened.

Means for Solving the Problems The evaporator of the present invention for achieving the above purpose has the following features:
A combination of an outer container containing a hydrated exothermic agent and an inner container containing a transpiration agent heated by the heat generated by the exothermic agent, which is built into the outer container and whose head is sealed between the outer container and the outer container. The evaporator is characterized in that the upper end opening of the inner container is closed by a top seal with holes laminated with a thermofusible film that is melted by the heat generated by the exothermic agent in the outer container.

Embodiments Next, embodiments of the present invention will be described with reference to the accompanying drawings.

The illustrated evaporator A, which is an embodiment of the present invention, includes an outer container 2 containing an appropriate hydrothermogenic agent 1 known per se, and a evaporator 3 heated by the heat generated by the exothermic agent 1, such as a heating evaporator. It has a structure in which it is combined with an inner container 4 housed in the outer container 2 which contains a molded insecticide, and the outer container 2 and the inner container 4 are connected and sealed at the head by tightening. The outer container 2 has a bottom plate 8 having a through hole 9 and a water-permeable mat 10 disposed on the top surface of the bottom plate 8.

In the inner container 4 of the evaporator A, a hole 7 having a heat-fusible film 6, which is melted by the heat generated by the exothermic agent 1 in the outer container 2 of the evaporator A, laminated at its upper opening...
A top seal 5 is attached, and the upper end opening of the inner container 4 is sealed by the seal 5.

When the bottom of the illustrated evaporator A is immersed in water in a water container B (see FIG. 4), water passes through the permeable mat 10 from the through hole 9 of the bottom plate 8 to the hydrothermal exothermic agent 1 in the outer container 2. is supplied, the exothermic agent 1 generates heat, and the heat-melting film 6 of the top seal 5 at the upper end opening of the inner container 4 is melted by the heat generated by the exothermic agent 1, and the hole 7 is opened. The evaporated components of the transpiration agent in the inner container 4 are radiated to the outside through the open holes 7.

In the illustrated embodiment of the present invention, water is drained from the bottom of the outer container 2 through the water-permeable mat 10.
The exothermic agent 1 inside the outer container 2 is absorbed completely at the bottom.
The generated steam is distributed throughout, thereby making the most of the heat generated by the exothermic agent 1, and efficiently heating the transpiration agent in the inner container 4.

In addition, in the illustrated example, the through hole 9 at the bottom of the outer container 2
The outer container 2 is a closed type in which the exothermic agent 1 is housed, and the water-permeable mat 1 at the bottom of the outer container 2 makes it possible to easily supply moisture to the exothermic agent 1.
0 also serves to prevent the exothermic agent 1 from falling out of the through hole 9 in the outer container 2.

Effects of the invention As described above, according to the invention, the top seal at the top opening of the inner container can be opened by the heat generated by the exothermic agent in the outer container, which heats the transpiration agent in the inner container. It is possible to provide a vaporizer of the type described above, in which it is ensured that the seal at the top opening of the vessel is opened simply, and this brings about the advantage that the above-mentioned usefulness of this type of vaporizer can be fully exploited. It will be done.

Moreover, the present invention has a structure in which the inner container is built into the outer container and the head is sealed between the outer container and the outer container, so there is extremely little heat loss when the exothermic agent generates heat. A favorable heating effect is obtained in which the inner container can be effectively heated by the heat generated by the exothermic agent from the initial exothermic stage of the exothermic agent, that is, the stage where the heat generation is not yet sufficient and the heat loss is most strongly affected. As the heating progresses, the heat-melting film of the top seal will be thermally melted, and the progress of the heating is appropriate and advantageous.
