The plurality of volatilization holes 42 have substantially the same length in the vertical direction, and are formed at predetermined intervals along the circumferential direction of the side wall portion 4 . The upper ends of the volatilization holes 42 lined up in this manner are spaced apart by the same length as the upper ends of the side wall portions 4 .

<1-3. volatilization body>
Next, the volatilization body will be described with reference to FIGS. 11 to 13. FIG. 11 is a perspective view of the volatilization body viewed from above, FIG. 12 is a perspective view of the volatilization body viewed from below, and FIG. 13 is a side view of the volatilization body attached to a container.

As shown in FIGS. 11 and 12, the volatilization body 30 is attached to the lid member 2, and extends upward from a rectangular plate-like substrate 51 and the opposite sides of the substrate 51. A pair of volatilization plates 52 and a pair of liquid absorption plates 53 extending downward from the substrate 51 are provided. Both the volatilization plate 52 and the liquid absorption plate 53 are formed in a rectangular shape. The outer diameter of the substrate is approximately the same as the outer diameter of the lid member. A rectangular through-hole 511 is formed in the center of the substrate 51 , and the discharge pipe 22 of the lid member 2 is inserted into this through-hole 511 . The sides of the through hole 511 facing each other are connected to the liquid absorption plates 53 described above. These liquid absorption plates 53 are formed in a rectangular shape and extend downward from the through holes 511 .

As shown in FIG. 13, when the volatilization body 30 is attached to the lid member 2, the discharge pipe 22 is inserted into the through hole 511, and the lower wall portion 212 of the lid member 2 is in contact with the upper surface of the substrate 51.

The volatilization body 30 is formed of a material capable of sucking up the chemical solution and volatilizing the chemical solution to the outside. be able to. However, in addition to synthetic fibers, pulp can be mixed. In this case, the content of the synthetic fibers in the volatilization body 30 is, for example, preferably 10% by mass or more, and more preferably 30% by mass or more. Examples of synthetic fibers that can be used include polyethylene terephthalate and nylon. Moreover, even when pulp or the like other than synthetic fibers is used, at least the surface of the volatilization body 30 is preferably formed of synthetic fibers in order to prevent yellowing as described later.

<1-4. Chemical solution>
The liquid medicine contained in the container 10 has an aromatic component as a functional component. However, in addition to these, various components such as a deodorizing component, an insect repellent component, and an antibacterial component can be contained. Such functional ingredients may be either oil-based or water-soluble. In addition, such a functional component can be blended with a component having a water vapor pressure of 0.01 to 20 hPa and easily volatilized. The mixing ratio of such components in the chemical liquid is preferably 0.25 to 2.5% by mass, more preferably 0.5 to 0.75% by mass. Specifically, limonene, linalool, linalyl acetate, α-pinene, and the like can be used as such components, and these function as fragrances. In addition, a component having a low water vapor pressure can also be contained, and examples of such components include vanillin and galacolid. These also function as perfumes.

Also, such a chemical solution can be produced by preparing, for example, surfactants, fragrances, preservatives, UV absorbers, and water. Then, the easily volatilizable functional component described above can be contained together with a predetermined fragrance or as a fragrance.

<2. Assembly and usage of chemical volatilization device>
Next, assembly of the chemical volatilization device will be described with reference to FIGS. 14 to 18. FIG. 14 is a cross-sectional view of the chemical volatilization device, FIG. 15 is an enlarged view of FIG. 14, and FIGS. 16 and 17 are cross-sectional views for explaining discharge of the chemical. 16 and 17, the valve member 23 and the protrusion 32 are omitted for convenience of explanation. First, a liquid medicine is contained in the container main body 1, and the lower end portion of the discharge portion 13 is closed with the cover member 2. As shown in FIG. Next, the volatilization body 30 is attached to the lid member 2 as described above. Subsequently, the cover member 20 is attached to the container 10 . At this time, the cover member 20 is attached so as to cover the container 10 to which the volatilization body 30 is attached from below. As shown in FIG. 14 , when the cover member 20 is completely attached, the ridges 41 of the cover member 20 fit into the attachment grooves 119 of the container body 1 . In addition, the lower end of the liquid absorption plate 53 of the volatilization body 30 and the lower end of the discharge pipe 22 are in contact with the portion where the groove 31 is formed on the upper surface of the bottom wall portion 3 .

Also, the protrusion 32 protruding from the upper surface of the bottom wall portion 3 presses the valve body 232 from the lower end of the discharge pipe 22 to move the valve body 232 upward. As a result, the through hole of the valve seat 231 is opened, and the chemical liquid in the container 10 is discharged from the discharge pipe 22 and accumulated in the groove 31 .

Next, volatilization of the chemical will be described. As shown in FIG. 16, the chemical liquid is discharged from the discharge pipe 22 and accumulated in the groove 31. Since the liquid absorption plate 53 of the volatilization body 30 is in contact with the groove 31, the chemical liquid accumulated in the groove 31 is absorbed. It is absorbed by the liquid plate 53 . The absorbed chemical liquid moves to the volatilization plate 52 via the liquid absorption plate 53 and the substrate 51, is volatilized from the volatilization plate 52, and is volatilized to the outside of the chemical volatilization device through the volatilization holes . As a result, the aromatic effect of the functional ingredient can be obtained.

By the way, when the chemical solution is stored in the groove 31 and the lower end of the discharge pipe 22 is in contact with the chemical solution in the groove 31, the inside of the discharge pipe 22 is filled with the chemical solution and air cannot enter. stops. However, when the chemical liquid accumulated in the groove 31 is absorbed by the volatilization body 30 and the water level of the chemical liquid in the groove 31 is lowered, as shown in FIG. Since a gap is formed between them, air enters from the lower end of the discharge pipe 22 , and the liquid medicine in the container 10 is pushed out by this air, and the liquid medicine is discharged from the discharge pipe 22 . Thereafter, the discharged chemical solution is accumulated in the groove 31, and when the water level of the chemical solution rises to the lower end of the discharge pipe 22 again, the discharge of the chemical solution stops because air cannot enter the discharge pipe 22.例文帳に追加In this way, the chemical is volatilized to the outside of the chemical volatilization device by the volatilizer 30 while the discharge and stop of the chemical are repeated.

When the liquid medicine in the container 10 runs out or becomes low, the liquid medicine can be replenished. Specifically, after removing the cover member 20 from the container 10 , the lid member 2 is removed from the container body 1 , and the liquid medicine is refilled into the container body 1 through the opening of the discharge portion 13 .

<3. Features>
According to the chemical volatilization device configured as described above, the following effects can be obtained.
(1) Since the lower end of the discharge pipe 22 is in contact with the groove 31, only when the water level of the chemical solution in the groove 31 is lowered and a gap is formed between the lower end of the discharge pipe 22 and the water surface of the chemical solution. Since the chemical liquid is not discharged from the container 10, it is possible to prevent the chemical liquid from overflowing the groove. Therefore, it is possible to limit the discharge amount of the chemical solution and prevent a large amount of the chemical solution from being discharged. In addition, since the cover member 20 has an internal space formed by the bottom wall portion 3 and the side wall portion 4, leakage of the chemical solution from this internal space is prevented, but the chemical solution is allowed to flow further into the groove 31 within the internal space. Therefore, it is possible to further prevent the chemical liquid from flowing out from the cover member 20 when, for example, the chemical liquid volatilization device is moved. Therefore, it is possible to prevent the surroundings of the chemical volatilization device from becoming dirty with the chemical.

Moreover, since the synthetic fiber is used for the volatilization body 30, it can suppress yellowing with time like pulp. That is, it is possible to prevent the volatilization body 30 from deteriorating in appearance. By the way, since synthetic fibers have a lower holding power for chemical liquid than pulp, there is a possibility that the chemical liquid may flow out from volatilization body 30 if it is excessively sucked up. On the other hand, in the present embodiment, the chemical is held in the grooves 31 as described above, and the chemical is controlled not to be excessively discharged, so that the volatilization body 30 suppresses excessive absorption of the chemical. can do. Therefore, even the volatilization body 30 made of synthetic fibers can be suitably used.

(2) The valve member 23 is provided on the discharge pipe 22 of the container 10 , and the valve member 23 is closed until the cover member 20 is attached to the container 10 and pressed by the projecting portion 32 . Therefore, it is possible to prevent the liquid medicine from leaking from the container 10 at the time of assembly. The chemical solution can volatilize at the same time as the attachment to the

(3) Since the third groove 44 extending downward from the lower end of each volatilization hole 42 is formed on the outer peripheral surface of the cover member 20, for example, even if the chemical liquid leaks from the volatilization hole 42 during replacement of the container 10, Since the liquid medicine is accumulated in the third groove 44 located below, it is possible to suppress the leakage of the liquid medicine from being conspicuous. Furthermore, since the chemical liquid can be held in the third groove 44, it is possible to prevent the surroundings of the chemical liquid volatilization device from being soiled by the chemical liquid.

(4) Since the fourth groove 45 is formed at the lower end of the side wall portion 4 of the cover member 20, for example, when the container 10 is replaced, the chemical liquid leaks from the volatilization hole 42 and flows downward along the side wall portion 4. Also, the chemical solution can be held in the fourth groove 45 . Therefore, it is possible to suppress the leakage of the chemical liquid from being conspicuous. Furthermore, since the chemical liquid can be held in the fourth groove 45, it is possible to prevent the surroundings of the chemical liquid volatilization device from being soiled by the chemical liquid.

(5) For example, in a chemical volatilization device of a type in which a chemical is stored in a container having an opening formed at the top, a liquid absorbing wick is inserted into the opening of the container, and the chemical is sucked up by the liquid absorbing wick and vaporized. In some cases, the high-pressure component was sucked up first and volatilized. Therefore, in order to secure the use for a certain period of time, it was necessary to add a large amount of components that are difficult to volatilize with a low vapor pressure to the chemical solution. As a result, it was difficult to freely design the fragrance tone. On the other hand, in the chemical liquid volatilization device according to the present embodiment, after the chemical liquid is discharged from the bottom of the container 10, the volatilization body 30 absorbs and volatilizes the chemical liquid, so the component with a high vapor pressure is volatilized first. is prevented. Therefore, since there is no need to add many components with low vapor pressure to the liquid medicine, the degree of freedom in designing the fragrance tone can be improved.

(6) Since the first to third projecting portions 116a to 116c projecting downward are formed on the inner surface of the ceiling wall portion 15 of the container main body 1, the chemical liquid adhering to the ceiling wall portion 15 is removed from the projecting portions 116a to 116c. It can be made easier to gather at the tip. As a result, it is possible to prevent the liquid medicine collected at the tips of the protrusions 116 a to 116 c from dropping and remaining adhered to the ceiling wall 15 . Therefore, it is possible to prevent the problem that the liquid medicine remains in the container 10 but cannot be discharged.

In particular, in the present embodiment, the protruding portions 116a to 116c are concentrically adjacent to each other, so that the chemical solution adhering between the protruding portions 116a to 116c can be easily guided to any of the protruding portions 116a to 116c. In addition, since the second and third projecting portions 116b and 116c are formed in a continuous circular shape, the chemical liquid adhering to any position on the top wall portion 15 is guided to either portion of the projecting portions 116b and 116c. It's easy to do. Therefore, it is possible to further prevent the chemical solution from remaining attached to the top wall portion 15 .

Also, the plurality of grooves 31 may be arranged in a pattern other than a grid pattern. Moreover, on the upper surface of the bottom wall portion 3, the periphery of the groove 31 may be flat, but at least a portion thereof may be inclined. That is, at least part of the surface around the groove 31 can be an inclined surface that inclines toward the groove 31 . As a result, the chemical solution adhering to the periphery of the groove 31 can be collected in the groove 31 .

However, in order to suck up the chemical, a part of the volatilization body 30 must be placed in contact with the chemical in the groove 31, and the lower end of the discharge pipe 22 and the volatilization body 30 are connected through the chemical in the groove 31. must be As long as the shape of the volatilization body 30 does not have to be the three parts 51 to 53 as described above, in order to efficiently volatilize the chemical liquid outside the device, a part of the volatilization body 30 faces the volatilization hole 42. It is preferable that it extends to the vicinity of the position where the Moreover, the material constituting the volatilization body 30 is not particularly limited as long as it can absorb the chemical solution and volatilize it to the outside.
