Hereinafter, an embodiment of the chemical solution vaporizer of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a chemical solution vaporizer 10 according to an embodiment. FIG. 2 is a side view of the chemical solution vaporizer 10 .

<1. Overall structure of the chemical vaporizer> The chemical liquid vaporizer 10 shown in FIGS. 1 and 2 is installed and used, for example, in a room or in the interior of an automobile. When the chemical-solution vaporizer 10 is installed in an automobile, the chemical-solution vaporizer 10 is fixed to the air outlet of the air conditioner via an adapter, for example, or is mounted on a dashboard. The structure of the adapter described here is not particularly limited, but as an example, it is assumed that a member of a holding mechanism is provided in a jig that can be fixed to the louver with the louver of the blowout port sandwiched therebetween. The holding mechanism detachably holds the chemical solution vaporizer 10 in a state of gripping any part of the chemical solution vaporizer 10 or the like. The chemical liquid vaporizer 10 includes a container 20 for accommodating the chemical liquid, and one or more rod-shaped vaporizers 70 inserted into the container 20 . In this embodiment, the chemical liquid vaporizer 10 includes three volatile bodies 70 . In other examples, the liquid medicine vaporizer 10 includes one, two or more than four volatiles 70 . In addition, unless otherwise specified, "upper" and "lower" described in this specification are defined based on the usage state shown in FIG. 1 .

The type of the chemical liquid contained in the container 20 is not particularly limited, but is typically a fragrance, a deodorant, an insect repellant, or a mixture thereof, and contains fragrance, deodorant, insect repellant, and coloring according to the purpose of use. additives, etc. The solvent contained in the chemical solution is appropriately selected depending on the type of additive to be used, and may be a hydrophilic solvent, a lipophilic solvent, or a mixture thereof. In the case where the medicinal solution contains a fragrance, it is preferable to include at least a lipophilic solvent as a solvent in order to increase the intensity of the fragrance. As the hydrophilic solvent, for example, water, ethanol, or a mixture thereof can be used. As the lipophilic solvent, for example, glycol ethers, isoparaffin-based solvents, or mixtures thereof can be used. Moreover, in order to solubilize functional components, such as a fragrance|flavor, a deodorant component, an insect repellent component, and a coloring material, a dissolving agent may be contained in a chemical|medical solution.

The volatile body 70 is inserted into the container 20 in a state where a part of the volatile body 70 protrudes from the container 20 . The volatile body 70 has a sufficient length relative to the height of the container 20 . The lower end portion 71 (refer to FIG. 3 ) of the volatile body 70 is located in the container 20 and located in the sealing member 50 . The position of the lower end portion 71 in the sealing member 50 can be arbitrarily selected. In the present embodiment, the lower end portion 71 is positioned above the center in the longitudinal direction of the sealing member 50 . The upper end portion 72 of the volatile body 70 is exposed to the outside of the container 20 . In order to improve the interior properties of the chemical liquid vaporizer 10 , the vaporizer 70 is placed in the container 20 in a state inclined with respect to the vertical direction. As shown in FIG. 1 , when the chemical liquid vaporizer 10 includes a plurality of volatile bodies 70 , for example, the plurality of volatile bodies 70 are arranged in the container 20 in a manner of extending radially in various directions.

The volatile body 70 has a structure capable of absorbing the medicinal liquid through the sealing member 50 against gravity by capillary phenomenon. As a result, the chemical solution in the container 20 can rise from the lower end portion 71 (see FIG. 3 ) to the upper end portion 72 along the volatile body 70 via the sealing member 50 , and be volatilized (naturally evaporated) from the outer surface of the volatile body 70 to the outside space. Thereby, the medicinal solution diffuses into the surrounding space where the medicinal solution vaporizer 10 is placed.

The shape and material of the volatile body 70 are not particularly limited as long as the chemical liquid can be absorbed through the sealing member 50 and volatilized to the outside. The volatile body 70 typically has an elongated and substantially cylindrical shape having micropores therein, and may contain natural materials such as rattan, or may contain synthetic resins such as polyethylene and polyacetal.

<2. Details of the container> FIG. 3 is a longitudinal cross-sectional view of the container 20 . As shown in FIG. 3 , the container 20 includes a container body 30 , a cover member 40 , a sealing member 50 , and a middle stopper 60 .

<2-1. Container body> The container body 30 includes a medicinal solution accommodating portion 31 for storing medicinal solution, a shoulder portion 32 connected to the upper end of the medicinal solution accommodating portion 31 , and a cylindrical mouth portion 33 connected to the upper end of the shoulder portion 32 . In the present embodiment, in plan view, the outer shape of the medicinal solution accommodating portion 31 is substantially oval, and the outer shape of the shoulder portion 32 and the mouth portion 33 is substantially circular. The centers of the medicinal solution accommodating portion 31 , the shoulder portion 32 and the mouth portion 33 are aligned. The maximum diameter of the medicinal solution accommodating portion 31 is larger than the maximum diameter of the shoulder portion 32 and the maximum diameter of the mouth portion 33 . The maximum diameter of the shoulder portion 32 is greater than the maximum diameter of the mouth portion 33 . An opening 33A into which the volatile body 70 is inserted is formed at the upper end of the mouth portion 33 . On the outer surface of the mouth portion 33, a male thread 33B that engages with the female thread 42 formed on the cover member 40 is formed. Furthermore, the male and female relationship of the two threads 33B and 42 may be reversed.

The material constituting the container body 30 can be arbitrarily selected. For example, the material constituting the container body 30 is glass or synthetic resin. In a preferred example, the container body 30 includes a transparent or translucent material to enhance interior decoration, and the remaining amount of the medicinal liquid can be visually recognized from the outside.

<2-2. Cover member> The cover member 40 is attached to the container body 30 so as to cover the mouth 33 and the sealing member 50 from above. The cover member 40 has a top surface 41 . The top surface 41 is formed with an opening 41A that communicates with the opening 33A of the mouth portion 33 . The shape and size of the opening 41A can be arbitrarily selected. In the present embodiment, the top surface 41 is substantially circular in plan view, and an opening 41A that is also substantially circular is formed in the center thereof. In addition, in the present embodiment, the maximum diameter of the opening 41A is smaller than the maximum diameter of the opening 33A. The material constituting the cover member 40 can be arbitrarily selected. For example, a synthetic resin can be selected as a material constituting the cover member 40, and a wood can also be selected from the viewpoint of improving designability. An example of the synthetic resin is polypropylene. Furthermore, when the chemical liquid vaporizer 10 is not used, the volatile body 70 is released from the container 20, and a cover (not shown) is attached to the cover member 40 to close the opening 41A.

The annular outer wall portion 43 extends downward from the outer peripheral edge of the top surface 41 . In addition, the annular inner wall portion 44 extends downward from the lower surface of the top surface 41 and inside the outer wall portion 43 . The inner wall portion 44 extends slightly outside along the outer peripheral edge of the opening 41A so as to surround the opening 41A. An inner thread 42 that engages with the outer thread 33B of the mouth portion 33 of the container body 30 is formed on the inner surface of the inner wall portion 44 . The outer wall portion 43 extends further downward than the inner wall portion 44 and covers the shoulder portion 32 and the mouth portion 33 . The outer wall portion 43 makes it impossible to visually recognize the portion other than the chemical solution storage portion 31 in the container body 30 from the outside, so that the designability of the chemical solution vaporizer 10 is improved.

<2-3. Sealing member> In order to close the opening 33A, the sealing member 50 is detachably attached to the mouth 33 so that even if the chemical solution vaporizer 10 is inclined, tipped, vibrated, or exposed to a high temperature environment, the chemical The liquid also does not leak from the opening 33A of the mouth portion 33 . In a typical example, when an external force acts due to contact of an object with the chemical liquid vaporizer 10 or the like, the chemical liquid vaporizer 10 is inclined or tipped. In addition, when the chemical solution vaporizer 10 is used in, for example, an automobile, the chemical solution vaporizer 10 may vibrate or the surrounding temperature may rise excessively. In this case, in order to prevent leakage of the medicinal solution, the sealing member 50 functions as a "plug" that seals the opening 33A of the mouth portion 33 . In the present embodiment, as described later, a middle stopper 60 is attached to the mouth portion 33 , and the mouth portion 33 defines the mouth portion of the container body 30 together with the middle stopper 60 . In this sense, below, the mouth portion 33 and the middle stopper 60 are collectively referred to as the mouth portion 11 , and the opening defined by the mouth portion 11 is referred to as the opening 11A. The sealing member 50 seals the opening 11A defined by the mouth portion 11 . In this embodiment, the shape of the sealing member 50 is a cylinder, and corresponds to the shape of the mouth portion 11 . However, in other examples, the shape of the sealing member 50 may be a quadrangular prism or the like, which can be appropriately selected according to the shape of the mouth portion 11 .

The outer peripheral surface of the sealing member 50 preferably has a shape in contact with the inner surface of the mouth portion 11 along the entire circumference. In addition, in a preferred example, at least a part of the sealing member 50 is inserted into the mouth portion 11 . In a more preferable example, the sealing member 50 is inserted into the mouth portion 11 by more than half in the height direction. In this embodiment, the entirety of the sealing member 50 is inserted into the mouth portion 11 . In this case, even when the chemical vaporizer 10 is inclined, tipped, vibrated, or exposed to a high-temperature environment, the sealing member 50 is less likely to come off from the mouth portion 11, thereby effectively suppressing the The situation in which the medicinal solution leaks and pollutes the surrounding environment. In addition, the sealing member 50 can not only suppress the needless waste of the medicinal solution due to the volatilization of the medicinal solution absorbed by the volatile body 70 to the surrounding environment, but also suppress the needless waste of the medicinal solution due to direct volatilization from the liquid surface.

The material constituting the sealing member 50 can be arbitrarily selected as long as it can absorb the chemical solution accommodated in the chemical solution accommodating portion 31 . For example, the material constituting the sealing member 50 is nonwoven fabric.

The sealing member 50 has an insertion hole 51 into which the volatile body 70 is inserted. The insertion hole 51 preferably does not penetrate the sealing member 50 . The number of the insertion holes 51 formed in the sealing member 50 is preferably the same as the number of the volatile bodies 70 used. In this embodiment, the sealing member 50 has three insertion holes 51 . The shapes of the three insertion holes 51 differ depending on the angle of the inserted volatile body 70 . In the present embodiment, two of the three insertion holes 51 extend at a predetermined angle with respect to the sealing member 50 , and one insertion hole 51 extends parallel to the sealing member 50 . By forming the three insertion holes 51 in this way, the volatile body 70 is fixed radially.

The size of the insertion hole 51 can be arbitrarily selected as long as it is a size that allows the volatile body 70 to be inserted. In this embodiment, the insertion hole 51 has a size that maintains the relative position of the volatile body 70 with respect to the sealing member 50 . In other words, the insertion hole 51 has a size substantially equal to or slightly larger than the maximum outer diameter of the volatile body 70 . Therefore, the volatile body 70 is fixed immovably with respect to the sealing member 50 by being inserted into the insertion hole 51 .

The lower end portion 52 of the sealing member 50 is located inside the chemical solution accommodating portion 31 . The position of the lower end portion 52 in the chemical solution accommodating portion 31 can be arbitrarily selected. In the present embodiment, the lower end portion 52 is in contact with the bottom wall 31A of the chemical solution accommodating portion 31 .

<2-4. Middle plug> The middle stopper 60 is attached to the inside of the mouth portion 33 so as to support the sealing member 50 . The middle bolt 60 is cylindrical, and includes a flange 61 at the upper end that is hooked on the top surface of the mouth portion 33 . The center pin 60 is rotatable relative to the mouth 33 . The middle plug 60 can also be engaged with the inner surface of the mouth 33 . Furthermore, in the present embodiment, a slight gap is formed between the sealing member 50 and the middle stopper 60 so that air can be taken in and out of the container 20 . Since the inside of the container body 30 is less likely to become a positive pressure, the ejection of the medicinal solution from the container body 30 is suppressed.

<3. Function and effect of the liquid medicine vaporizer> According to the medicinal solution vaporizer 10 , the medicinal solution accommodated in the medicinal solution accommodating portion 31 is sucked by the sealing member 50 . The medicinal liquid sucked by the sealing member 50 is further sucked by the volatile body 70 and volatilized to the outside. Compared with the case where the volatile body 70 directly absorbs the medicinal solution stored in the medicinal solution accommodating portion 31, the amount of liquid absorbed by the volatile body 70 is small, so that excessive volatilization of the medicinal solution is suppressed. Therefore, the chemical liquid vaporizer 10 can be used for a long period of time.

<4. Effects of the present embodiment> In the chemical liquid vaporizer 10 configured as above, the following effects can be further obtained.

<4-1> The lower end portion 71 of the volatile body 70 is located above the center in the longitudinal direction of the sealing member 50 . Therefore, a state in which the volatile body 70 is located above the liquid level of the medicinal solution accommodated in the medicinal solution accommodating portion 31 is easily formed, so that the volatile body 70 can be prevented from absorbing the medicinal solution excessively.

<4-2> The lower end portion 52 of the sealing member 50 is in contact with the bottom wall 31A of the chemical solution accommodating portion 31 . Therefore, even if the liquid level of the medicinal solution in the medicinal solution accommodating portion 31 drops, all the medicinal solution can be sucked by the sealing member 50 .

<4-3> Since the sealing member 50 has the insertion hole 51 , the volatile body 70 can be easily inserted into the sealing member 50 .

<4-4> Since the insertion hole 51 of the sealing member 50 has a size to maintain the relative position of the volatile body 70 with respect to the sealing member 50 . Therefore, the position of the volatile body 70 relative to the sealing member 50 is stabilized.

<4-5> Since at least a part of the sealing member 50 is inserted into the inside of the mouth portion 11 , the sealing member 50 is protected by the mouth portion 11 . Therefore, the sealing member 50 is less likely to deteriorate.

<4-6> Since the sealing member 50 is inserted into the mouth portion 11 by more than half in the height direction, a wide range of the sealing member 50 is protected by the mouth portion 11 . Therefore, the sealing member 50 is less likely to deteriorate.

<5. Modifications> The above-described embodiment is an example of a form that the chemical solution vaporizer according to the present invention can take, and is not intended to limit the form. The chemical solution vaporizer according to the present invention may take a form different from the form illustrated in the embodiment. One example is a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. An example of a modification of the embodiment is shown below.

<5-1> The configuration of the chemical solution vaporizer 10 is not limited to that shown in the above-described embodiment, and can be arbitrarily changed. For example, at least one of the cover member 40 and the center pin 60 may be omitted. When the middle stopper 60 is omitted, the sealing member 50 can be attached to the mouth portion 33 so as to be in contact with the inner surface of the mouth portion 33 .

<5-2> The structure of the container main body 30 is not limited to what was shown in the said embodiment, It can change arbitrarily. For example, the shoulder portion 32 and the mouth portion 33 may be omitted. In this case, the sealing member 50 is attached to the container main body 30 so as to close the opening of the medicinal solution accommodating portion 31 .

<5-3> The structure of the volatile body 70 is not limited to that shown in the above-mentioned embodiment, and can be changed arbitrarily. FIG. 4 is a cross-sectional view of the volatile body 70 included in the chemical liquid vaporizer 10 according to the modification. In the modified example, the volatile body 70 includes polyethylene terephthalate and polyurethane, and may have many amorphous micropores 70A therein. In addition, a plurality of grooves 73 may be formed on the outer surface of the volatile body 70 . The plurality of grooves 73 extend in stripes from the lower end portion 71 (see FIG. 3 ) to the upper end portion 72 along the axial direction of the volatile body 70 . That is, the cross section of the volatile body 70 has a contour line that is not smooth along the circumferential direction, but has uneven contours. In addition, these grooves 73 are arranged at substantially equal intervals along the circumferential direction of the volatile body 70 . The medicinal solution is sucked not only along the fine holes 70A but also along the grooves 73 by the capillary phenomenon. Therefore, a large amount of chemical liquid tends to adhere to the outer surface of the volatile body 70 of the present embodiment. In addition, since air can enter and exit inside and outside the container body 30 through the grooves 73 provided in the volatile body 70 , it is difficult for the inside of the container body 30 to become a positive pressure. Therefore, the ejection of the chemical solution can be suppressed. In addition, the sealing member 50 is preferably made of a material that is softer than the material constituting the volatile body 70 . An example of this is non-woven fabric. In this case, in the portion of the volatile body 70 inserted into the sealing member 50 , the portion other than the groove 73 is effectively bitten into the sealing member 50 , so that the volatile body 70 is prevented from coming out of the sealing member 50 .
