[Detailed description of the device]

[0001]

[Industrial application] The present invention sucks the chemical liquid in a chemical liquid tank with a suction core, and heats the suction core with a heating element to absorb the chemical liquid such as an insecticide, a fragrance, or a repellent. The present invention relates to a chemical liquid volatilization device for heating and volatilizing.

[0002]

2. Description of the Related Art As a conventional chemical liquid volatilization device, there is one disclosed in Japanese Utility Model Laid-Open No. 62-49586 filed by the applicant of the present application. The chemical solution volatilization device according to the prior application has a configuration in which at least one of the chemical solution tank and the heating element is positionally movable in the axial direction of the heating element of the heating element and supported by an outer container. By moving either one in the axial direction, the heating area by the heating element of the suction core is changed to adjust the volatilization amount of the chemical liquid.

[0003]

In the case of the above-mentioned prior application example, either one of the chemical solution tank and the heating element is moved in the axial direction to change the heating area by the heating element of the suction core and to volatilize the drug. The number of days used was changed by changing the amount, and it was not possible to use it for a certain number of days or for a long time. In addition, it was not possible to change the number of days of use while keeping the volatilization amount constant.

The present invention has been made in view of the above, and it is possible to obtain a volatilization time of a chemical solution proportional to the capacity of the chemical solution tank without changing the volatilization rate of the chemical solution per unit time, and An object of the present invention is to provide a chemical solution volatilization device that can easily perform the replacement work of chemical solution tanks having different capacities when only different bottom vessels need to be replaced when exchanging different chemical solution tanks.

[0005]

In order to achieve the above object, a chemical liquid volatilization device according to the present invention is housed in an upper container 1 having a heating element 3 on the upper part thereof and an inner lower part of the upper container 1.
Further, in a chemical solution volatilization device comprising a chemical solution tank 4a, 4b having a suction core 6 projecting upwardly facing the heating element 3 and a bottom container supporting the chemical solution tank while closing the lower end portion of the upper container 1, At least two types of chemicals with different heights
The tanks 4a and 4b and the chemical liquid tanks 4a and 4b are
Support each suction core 6 at a position facing the heating element 3.
As described above, the position of the support surface for supporting the chemical liquid tank is composed of at least two types of bottom containers 7a and 7b which are vertically different.

[0006]

[Operation] With the bottom container engaging the lower end of the upper container 1, the medicine
By exchanging the liquid tank can be divided to use different chemical tank capacity that fits the bottom container.

[0007]

EXAMPLES Examples of the present invention will be described with reference to the drawings. FIG. 1 shows a basic use mode of the present invention.
Is an upper container having a volatilization hole 2 on its upper surface.
A cylindrical heating element 3 is provided above the vaporization hole 2 and above the vaporization hole 2.
Is stuck. Reference numeral 4a denotes a chemical liquid tank, and a suction core 6 fitted and held in the injection port 5 in the form of a tight plug is projected over a predetermined length above the chemical liquid tank 4a.
A bottom container 7a closes the bottom of the upper container 1. The chemical solution tank 4a has such a thickness that it can be inserted into the upper container 1 from the lower side, and its vertical size is supported by the bottom container 7a fitted and held at the lower end of the upper container 1. In this state, the suction core 6 has a size facing the heating element 3 of the upper container 1 with a predetermined facing area. Reference numeral 9 is a vent provided in the upper container 1. FIG. 2 shows a different usage mode of the present invention.
Is a chemical liquid tank, and the chemical liquid tank 4b is smaller in size in the height direction than the chemical liquid tank 4a used in the use example shown in FIG. 1 and has a smaller capacity than the chemical liquid tank 4a. Has become. In this case, the bottom container 7b in which the position of the supporting surface for supporting the chemical liquid tank 4b is changed upward
To use.

In the above structure, the chemical liquid tanks 4a, 4b
Is stored in the upper container 1 by being supported by the bottom containers 7a, 7b that close the lower end of the upper container 1, and the chemical liquid tank 4a,
The suction core 6 of 4b faces the heating element 3 over a predetermined facing area. The chemical liquid sucked up by the suction core 6 is heated by the heating element 3 and volatilized from the volatilization hole 3. By properly using the bottom containers 7a and 7b, the chemical liquid tanks 4a and 4b stored in the upper container 1 are changed to those having different capacities, whereby the usage time is changed with the same volatilization amount. It

[0009]

According to the present invention, the volatilization time of the chemical liquid can be obtained in proportion to the capacity of the chemical liquid tank without changing the volatilization amount of the chemical liquid per unit time, and the chemical liquid tanks having different capacities can be replaced. At this time, it is only necessary to replace it with a bottom container suitable for this, and it is possible to easily replace the chemical liquid tanks having different capacities.
