Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heating evaporation device that heats and evaporates chemical liquids such as insecticides, repellents, and aromatic agents.

[0002]

[Prior art]

 As a conventional heating evaporation device, as shown in JP-A-58-45670 and JP-A-1-137169, an upper container provided with a heating element and a container for containing a chemical liquid container for heating evaporation (hereinafter, chemical liquid container). One that is detachably connected by sliding it up and down with a bottom container equipped with a part and hooking or screwing it in (Figs. 4 and 5), as shown in Japanese Examined Patent Publication No. 52-121 06 and Japanese Utility Model Publication No. 2-87481. The one in which the screw part engraved on the upper part of the drug solution container is screwed or hooked into the holder provided inside the heating evaporation device to house the drug solution container (Fig. 6), as shown in Japanese Utility Model Publication No. 4-212275. A heating and evaporation device in which the upper container equipped with a heating element is attached to the head of the chemical solution container to expose the periphery of the chemical solution container, and the bottom part of the chemical solution container is set on a pedestal to hold the chemical solution container for a stable feeling. Heat evaporation device ( 7), and the like.

Further, regarding the chemical liquid containers, SAIKAI Sho 63-187868, SAIKAI HEI 4-97580, HEI 1-223487, HEI 1-23488, HEI 1-223489, HEI 1-223490, HEI There is one shown in flat 1-23491. However, all of the above-mentioned prior application examples are intended to simply change the chemical liquid volume or to change the shape of the container from the viewpoint of design, and are not considered in terms of use. Is the actual situation.

[0004]

[Problems to be solved by the device]

 Among the above-mentioned prior application examples, for example, the heating evaporation devices of Japanese Utility Model Laid-Open Nos. 63-187868 and 4-97580 can change the number of days of use by changing the shape of the chemical solution container. However, when using a container with a smaller capacity than the maximum capacity liquid container, it is necessary to install a spacer on the bottom container, and in that case, a means is required to match the spacer with the shape of the liquid container. Furthermore, if the spacer is lost, it may happen that the heating evaporation device cannot be used. In addition, although the invention of the application containers 1-23487, 1-23490, and 1-23491 has some contrivances in terms of the design of the drug solution container, the heating evaporation shown in FIGS. When mounted on a device, that is, a device for setting a drug solution container in the bottom container, the chemical solution bottle may have poor stability. Further, regarding those disclosed in the above-mentioned Japanese Patent Application Nos. 1-23487, 1-249049, 1-234949, 1-234949 and 1-23489, the shape of the body portion of the liquid container is described. Since it varies from the upper part to the lower part, it can be considered that it is difficult to predict the residual liquid amount in the chemical solution container with the heating evaporation device (Fig. 7) where the chemical solution container is exposed.

[0005]

[Means and Actions for Solving the Problems]

 The present invention has been made in view of the above situation, and the maximum diameter of the body portion of the chemical liquid container and the maximum height from the bottom to the mouth of the chemical liquid container are made constant, and the shape of the body portion is changed to increase or decrease the chemical liquid volume. At the same time, the number of days used can be adjusted. For example, in a heating evaporation device with a bottom container and a pedestal, by matching the maximum diameter and height of the drug solution container used in the present invention with the drug solution containers that are commercially available in the past, it is possible to use drug solution containers with different capacities. It is possible to change the number of days of use, and since the maximum diameter is even, the stability is good even when set on the bottom container and pedestal. Although it is also useful in a heating evaporation device where bottles are exposed, changes in the shape of the body of multiple chemical liquid containers should be taken into consideration in order to make it easier to predict the amount of residual liquid in the chemical liquid containers. A circular shape to an oblong shape, or a square shape to an oblong shape is preferable, and it is appropriate to design the liquid medicine container so that the diameter of the body portion is constant or slightly widens from the upper side to the bottom side.

[0006]

【Example】

 Hereinafter, the heating evaporation device of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. FIG. 1 is a front view and a right side view of a drug solution container 1 used in the present invention, and FIGS. 2 and 3 are other drug solution containers. These liquid medicine containers 1 are equipped with liquid absorption wicks 2 for absorbing the liquid medicine at the center, and by changing the shape of the liquid body 1 with the maximum diameter of the body and the height of the container being constant. It is configured as a plurality of chemical liquid containers with different capacities. As the drug solution, an insecticide, repellent, fragrance, or the like dissolved in an arbitrary solvent is used. In particular, an insecticide represented by a pyrethroid agent is suitably applied to the present invention. Further, the composition and shape of the liquid absorbent core 2 are not limited at all, and can be appropriately selected according to the kind of the liquid medicine and the purpose of use.

Next, a typical heating evaporation device for loading the chemical solution container 1 is shown in FIGS. 4 to 7. The heating evaporation device shown in FIGS. 4 and 5 slides an upper container 4 having a heating element 3 and a bottom container 6 having a receiving portion 5 for a liquid medicine container 1 having a liquid absorbent core 2 up and down to hook. Although it is used by pushing or screwing it, the drug solution container 1 of the present invention can be easily set on these heating evaporation devices, and since the maximum diameter is substantially the same as the bottom part of the drug solution container, it is very stable.

Further, the heating evaporation device shown in FIG. 6 is one in which the drug solution container 1 is screwed or hooked into a holder 7 provided in an upper container 4 provided with a heating element 3 to store the drug solution container 1. It can be set without difficulty by keeping the height constant.

Further, in the heating evaporation device shown in FIG. 7, the upper container 4 provided with the heating element 3 is attached to the chemical liquid container head 8 to expose the periphery of the chemical liquid container. According to the present invention, the lower portion of the liquid medicine container 1 can be reliably set on the pedestal 9 to give a sense of stability. Moreover, if the liquid medicine container shown in FIG. 1 or FIG. It is more preferable because the liquid volume is easily predicted.

[0010]

[Test example]

 As one of a plurality of chemical liquid containers, a standard chemical liquid container with a circular trunk cross section (60 days, 45 ml of chemical liquid) was used, and another chemical liquid container shown in Table 1 (30 days, 30 ml of chemical liquid) Then, a kerosene solution containing 1.3% (w / v) of d-T80-flamethrin was charged, and then loaded into the heating evaporation device of FIG.

[0011]

[Table 1]

[0012] As a result of the test, in the case of using another chemical solution container of the present invention in which the maximum diameter and the maximum height are constant with respect to the standard container and the body section has an oval shape, the volatility and usability are improved. While there was no problem with the above, in the container (Control 1) in which the maximum height of the container was changed to adjust the amount of chemical liquid, a spacer is required and the change in the length of the liquid absorption core affects the volatilization performance. It has been suggested. In addition, a problem such as deformation also occurred in the container having the waist center portion (Control 2), and the usefulness of the heating evaporation device of the present invention was confirmed.
