Description

[Detailed description of the invention] [Industrial field of application] This invention uses a suction wick to suck up a chemical solution in a chemical tank, and heats the suction wick with a heating element to suck up insecticides and fragrances. This invention relates to a chemical liquid volatilization device that heats and volatilizes a chemical liquid such as a repellent.

[Conventional technology]

As a conventional chemical liquid volatilization device, there is one disclosed in Japanese Utility Model Application Publication No. 62-49586 filed by the applicant of the present application.

The chemical liquid volatilization device according to the above-mentioned prior application has a structure in which at least one of the chemical liquid tank and the heating element is movable in the axial direction of the heating element and is supported by an outer container. By moving either one in the axial direction, the heated area by the heating element of the suction wick is changed, and the amount of volatilization of the chemical solution is adjusted.

[Problem to be solved by the invention] In the case of the above-mentioned prior application, either the chemical liquid tank or the heating element is moved in the axial direction to change the heating area by the heating element of the suction wick. The number of days of use can be changed by changing the amount of volatilization.
It was not something that could be used for a certain number of days or for a long period of time. Furthermore, it was not possible to change the number of days of use while keeping the amount of volatilization constant.

[Means and actions for solving problems]

The present invention was developed in consideration of the above-mentioned problems, and it is possible to change the volatilization time of the chemical solution without changing the amount of volatilization of the chemical solution per unit time by making it possible to use chemical liquid tanks with different capacities. The device is designed to provide a chemical liquid volatilization device that can vaporize chemical liquids, and its configuration consists of an upper container 1 provided with a heating element 3 on the upper part, and an absorber housed in the inner lower part of the upper container 1 and facing the heating element 3 in the upper part. A spacer 8 whose upper end fits into the lower end of the upper container 1 and whose lower end has the same shape as the lower end of the upper container 1; 1 and the lower end of the spacer 8, and supports the chemical solution tanks 4a, 4b, and the lower end of the upper container 1 is directly fitted into the bottom container 7. At least two types of chemical liquid tanks having different capacities can be used, which are closed with the bottom container 7 or closed with the bottom container 7 via the spacer 8 and supported by the bottom container 7.

〔Example〕 Embodiments of the present invention will be described based on the drawings.

FIG. 1 shows the basic usage of the present invention. In the figure, 1 is an upper container having volatilization holes 2 on the upper surface. A cylindrical heating element 3 is fixed thereto. 4a
1 is a chemical liquid tank, and from the upper part of this chemical liquid tank 4a, a suction wick 6 that is tightly fitted and held in an injection port 5 protrudes over a predetermined length. 7 is a bottom container that closes the bottom of the upper container 1. 8 is a spacer, the lower end of which fits into the bottom container 7, and the upper end which fits into the lower end of the upper container 1, so that the spacer 8 is engaged and held so that it cannot easily slip out. . The bottom container 7 is adapted to directly fit into the lower end of the upper container 1 and to be held in engagement therewith.

The chemical solution tank 4a has a thickness such that it can be inserted into the inside of the upper container 1 from below, and its size in the vertical direction is the same as that of a bottom container that is fitted and held at the lower end of the upper container 1 via a spacer 8. While supported by 7,
The suction wick 6 is sized to face the heating element 3 of the upper container 1 with a predetermined opposing area.
9 is a ventilation hole provided in the upper container 1 and the spacer 8.

In the above configuration, the chemical solution tank 4a is supported by the bottom container 7 which closes the lower end of the upper container 1 via the spacer 8, and is housed in the upper container 1. At this time, the suction core 6 of the drug solution tank 4a is connected to the heating element 3. are opposed to each other over a predetermined opposing area. The chemical liquid sucked up by the suction wick 6 is heated by the heating element 3 and volatilized from the volatilization hole 3.

FIG. 2 shows a different usage mode of the present invention. In the figure, 4b is a chemical tank, and this chemical tank 4
b is smaller in height in the height direction than the chemical tank 4a used in the usage example shown in FIG. It's summery.

In this mode of use, the chemical liquid tank 4b is supported by the bottom container 7 which is directly engaged and held at the lower end of the upper container 1, and the spacer 8 is not used. According to this mode of use, the amount of volatilization of the chemical solution per unit time is the same as in the case of the mode of use shown in FIG.

FIGS. 3 and 4 show an example in which the bottom container 7a is deeper than the upper container 1a in the embodiment shown in FIGS. 1 and 2, and in addition to this bottom container 7a, a spacer is 8 may also be provided with ventilation holes 9.

In the above configuration, the heating element 3 is not limited to a cylindrical shape, but may have any shape such as a U-shape or a two-shape shape as long as it can face the side surface of the suction wick 6 and sufficiently heat it.

Further, the bottom container and the spacer are engaged with the upper container by using ordinary locking means that can be easily attached and removed, such as press-fitting, screwing, and hooking. The upper container and the spacer can be provided with ventilation holes, holes for electrical cords, hooks for fixing the two, and the like.

The ventilation hole 9 is provided in at least one of the upper container, the bottom container, and the spacer.

[Effect of idea]

According to the present invention, at least two types of chemical liquid tanks 4a and 4b with different capacities can be installed in the upper container 1 without changing the positions of the heating element 3 and the suction wick 6, and therefore the chemical liquid can be supplied per unit time. Different chemical volatilization times proportional to the capacity of the chemical tank can be obtained without changing the volatilization amount.

The drawings show an embodiment of the present invention, and are shown in FIG.
FIG. 2 is a cross-sectional view showing a different usage example, and FIGS. 3 and 4 are external views showing different usage conditions in other embodiments. 1 is an upper container, 3 is a heating element, 4a and 4b are chemical liquid tanks, 6 is a suction wick, 7 and 7a are bottom containers, and 8 is a spacer.
