Description

[Technical field]

[0001] The present invention relates to an evaporator for evaporating fragrances, deodorants, insect repellents, etc. (hereinafter referred to as fragrances, etc.), and in particular to an evaporator for fragrances that is suitable for cases where it is desired to easily adjust the amount of fragrances, etc. that are evaporated. [Background technology]

[0002] The volatile components constituting air fresheners, deodorants, insect repellents, etc. have different fragrances and effects depending on the amount of volatilization. For this reason, the desired amount of volatilization of air fresheners may vary depending on the preferences of the user and the environment. For this reason, volatilization devices capable of adjusting the amount of volatilization of air fresheners, such as those disclosed in Patent Document 1 and Patent Document 2, have been proposed. For example, the volatilization device disclosed in Patent Document 1 is configured to store air fresheners in a container body and adjust the amount of volatilization of air fresheners by changing the open / close state of a lid placed on the container. According to a volatilization device configured in this way, the opening area of ​​the container is physically changed, so it is considered that the amount of volatilization of air fresheners can be effectively changed. However, a volatilization device configured in this way requires a lid that can adjust the opening and closing angle to the container, which causes concerns that the shape becomes complicated and the manufacturing cost increases.

[0003] On the other hand, the volatilization device disclosed in Patent Document 2 is for volatilizing liquid aromatics contained in a container, and is based on the principle of pulling up a suction volatilization member soaked in the aromatics in the container from the opening of the container, and volatilizing the aromatics from the suction volatilization member protruding from the container. In a volatilization device having such a basic configuration, the amount of volatilization of the aromatics can be changed by changing the amount of pulling up the suction volatilization member, that is, the amount of protrusion of the suction volatilization member from the container opening. However, in a volatilization device having such a configuration, the size (height) of the volatilization device changes significantly depending on the change in the amount of volatilization. For this reason, if stability in installation is required, it becomes necessary to make the container larger. For this reason, the presence of the volatilization device becomes large, and it may spoil the aesthetics of the installation location. [Prior art documents] [Patent documents]

[0005] Therefore, the objective of this invention is to provide an evaporative device that can effectively adjust the amount of volatilization with a simple configuration and also has excellent design when installed. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the volatilization device of the present invention is a device for volatilizing a medicinal solution, which has at least a portion that is immersed in the medicinal solution and has the property of absorbing the medicinal solution and volatilizing it, and an expansion member that is made of a cloth that is flexible and has an affinity for the medicinal solution and engages with a portion of the reed other than the immersion portion, and which is characterized in that the effective volatilization area can be changed by deforming the shape of the expansion member.

[0007] In addition, the volatilization device having the above-mentioned characteristics can be provided with a plurality of the reeds, and the expansion and contraction member can be stretched between the plurality of the reeds. In this case, the drug solution is transferred from each lead to the expansion and contraction member, thereby increasing the volatilization effect of the expansion and contraction member.

[0008] Furthermore, the volatilization device having the above-mentioned characteristics can be configured to have a single reed and a shape-maintaining member disposed on the expansion / contraction member, thereby making it possible to maintain a set shape. By having such characteristics, the volatilization device can be simplified. Effect of the Invention

[0009] According to the volatilization device having the above-mentioned characteristics, it is possible to effectively adjust the amount of volatilization with a simple configuration. In addition, the shape of the volatilization device can be changed, and the design when installed is excellent. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiment of the volatilization device of the present invention will be described in detail with reference to the drawings. Note that the embodiment shown below is a part of the preferred embodiment for carrying out the present invention, and even if a part of the configuration is changed, it can be considered as a part of the present invention as long as the effect is achieved.

[0012] [First embodiment: configuration] First, the configuration of the volatilization device according to the first embodiment will be described with reference to Fig. 1. The volatilization device 10 according to this embodiment is a device for volatilizing a liquid medicine stored in a container 30. Here, the medicine refers to a fragrance, a deodorant, an insect repellent, or the like, which exerts various effects by the volatilized components, and is collectively referred to as a medicine liquid 32 in the following embodiment.

[0013] The volatilization device 10 according to the present embodiment is basically composed of a reed 12 and an expansion / contraction member 14. The reed 12 is an element that sucks up the medicinal solution 32 stored in the container 30, volatilizes a part of it, and spreads it to the expansion / contraction member 14, which will be described in detail later. The reed 12 according to the present embodiment is preferably composed of a material having a conduit (including those due to capillary action) along the longitudinal direction, and is preferably a collection of chemical fibers (e.g., polyester) having affinity for the medicinal solution 32, or, in particular, natural materials such as rattan and bamboo. The reed 12 according to the present embodiment has at least a part of an immersion portion 12a that is immersed in the medicinal solution 32, and is configured so that the other portion protrudes outside the medicinal solution 32. The number (number) of the reeds 12 constituting the volatilization device 10 is not limited and can be one to more than one, but in the example shown in FIG. 1, the number of the reeds 12 is two.

[0014] The expansion and contraction member 14 functions to spread the drug solution 32 through the lead 12 and to volatilize it. For this reason, the expansion / contraction member 14 is preferably made of a cloth that is flexible and has affinity for the chemical solution 32, that allows its shape to be changed, and that has a structure that allows the chemical solution to easily propagate on its surface or inside. Here, the cloth in this application includes not only general woven fabrics such as natural fibers and chemical fibers, but also nonwoven fabrics such as paper. Furthermore, the woven fabric includes not only fabrics with tight weaves, but also fabrics with a mesh-like weave having gaps between the weaves. When the expansion / contraction member 14 is made of natural materials, it can be made of hemp, Japanese paper, etc.

[0015] The expansion / contraction member 14 can be changed in shape by bending or rolling (rolling), so there is no need to specify a specific planar shape. In this embodiment, as shown in FIG. 1, the planar shape is a rectangle, and the bag-shaped portion 14a is formed at both longitudinal ends. The bag-shaped portion 14a is a portion into which the lead 12 described above is inserted, and the lead 12 and the expansion / contraction member 14 can be engaged by inserting the lead 12 into the bag-shaped portion 14a. The bag-shaped portion 14a can be formed by slightly folding back both longitudinal ends of the expansion / contraction member 14, and joining the folded back ends to the edge located at the tip side of the lead 12 when the lead 12 is inserted into the bag-shaped portion 14a. In addition to sewing, various methods such as adhesion, fusion, and stapling can be used for joining when forming the bag-shaped portion 14a.

[0016] [Actions and Effects] The volatilization device 10 configured as described above can perform its function by being placed in a container 30 in which a chemical solution 32 is stored, as shown in Figures 2 and 3. The installation method is as follows. First, the lead 12 is inserted into the opening of the container 30 in which the chemical solution 32 is stored, and the immersion part 12a is immersed in the chemical solution 32. Next, the position and inclination of the lead 12 are adjusted to change the shape (opening degree) of the expansion / contraction member 14, thereby adjusting the effective volatilization area. Here, the effective volatilization area changes depending on the blowing condition of the wind against the expansion / contraction member 14, the contact condition with the adjacent cloth (constituting the expansion / contraction member 14), the condition of the gap, etc., and refers to the area of ​​the part where the chemical solution 32 is efficiently volatilized. Specifically, as shown in Figure 2, the wider the expansion / contraction member 14 is, the wider the effective volatilization area becomes, and as shown in Figure 3, the more the contact or adjacent surface area of ​​the fabric that makes up the expansion / contraction member 14 is increased by wrapping or folding the expansion / contraction member 14 around the reed 12 (not shown), the worse the air circulation over the surface of the fabric becomes, and the narrower the effective volatilization area becomes.

[0017] FIG. 4 is a graph showing the difference in volatilization characteristics when the expandable member 14 is expanded to widen the effective volatilization area (for example, the form shown in FIG. 2) and when the expandable member 14 is rolled to narrow the effective volatilization area (for example, the form shown in FIG. 3). The experiment was conducted in a state where the volatilization device 10 was set in a container 30 in which the medicinal liquid 32 was stored, and the volatilization time was shortened by blowing air to the volatilization device 10 with a blower. As can be seen from FIG. 4, the amount of volatilization (weight change) of the medicinal liquid 32 per hour is larger when the expandable member 14 is expanded rather than rolled, i.e., when the effective volatilization area is larger. In particular, it can be seen that the time until 80 g of the medicinal liquid 32 volatilizes is about twice as long.

[0018] In this way, the volatilization device 10 according to this embodiment can effectively adjust the amount of volatilization of the medicinal solution 32 by a simple configuration and means, such as changing the effective volatilization area of ​​the expansion / contraction member 14 by adjusting the position of the reeds 12. In addition, since the state change of the expansion / contraction member 14 according to preference can be visually enjoyed, it can be said that the design at the time of installation is also excellent.

[0019] Furthermore, in the case of a configuration in which multiple leads 12 are provided for one expansion / contraction member 14, as in the case of the volatilization device 10 according to this embodiment, the medicinal solution 32 is transmitted from each lead 12 to the expansion / contraction member 14. This makes it possible to improve the transmission efficiency of the medicinal solution 32 to the expansion / contraction member 14, and to increase the difference in the amount of volatilization when the effective volatilization area of ​​the expansion / contraction member 14 is changed.

[0020] [Second embodiment] Next, the volatilization device according to the second embodiment will be described with reference to Fig. 5 and Fig. 6. The volatilization device 10A according to this embodiment has the same basic components. Therefore, the same reference numerals are used in the drawings to designate the same components, and detailed descriptions thereof will be omitted.

[0021] The volatilization device 10A according to this embodiment is characterized in that it has one reed 12 and a shape-retaining member 16 is arranged on the expansion / contraction member 14. The shape-retaining member 16 may be, for example, a small-diameter wire, as long as it is a member that can be easily plastically deformed by an external force. As described above, the expansion / contraction member 14 is made of a flexible cloth. Therefore, if it is only engaged with one reed 12, the end located opposite to the engagement end will hang down, making it difficult to expand the effective volatilization area. For this reason, by arranging the shape-retaining member 16 on the expansion / contraction member 14, the sagging of the cloth (expansion / contraction member 14) can be suppressed, and the desired shape (expansion / contraction state) can be maintained. That is, although the examples shown in Figs. 5 and 6 both show the expansion / contraction member 14 in an expanded state (the state in which the effective volatilization area is the widest), the shape-retaining member 16 can be deformed to make the expansion / contraction member 14 in a folded state or in a state wrapped around the reed 12 as shown in Fig. 3.

[0022] The shape-retaining member 16 may be disposed on the expansion / contraction member 14 by forming a bag-like portion (not shown) on the expansion / contraction member 14 and inserting the member into the bag-like portion, as in the case of the lead 12, or may be attached to the expansion / contraction member 14 or may be disposed in a wavy pattern so as to sew the shape-retaining member 16 itself. The shape-retaining member 16 may be disposed along the upper side of the expansion / contraction member 14 from the end on the side where the lead 12 is disposed, as shown in FIG. 5. In addition, as shown in FIG. 6, when the lead 12 is configured to be disposed in the center of the expansion / contraction member 14 in the longitudinal direction, the shape-retaining member 16 may simply be disposed along the upper side of the expansion / contraction member 14. It goes without saying that the shape-retaining member 16 may be provided on the expansion / contraction member 14 of the volatilization device 10 according to the first embodiment.

[0023] [effect] Even with the volatilization device 10A having such a configuration, it is possible to suck up the medicinal solution 32 by the reed 12, transmit the medicinal solution 32 from the reed 12 to the expansion / contraction member 14, propagate the medicinal solution 32 by the expansion / contraction member 14, and adjust the effective volatilization area of ​​the expansion / contraction member 14. Thus, similar to the volatilization device 10 according to the above embodiment, the amount of volatilization of the medicinal solution 32 can be effectively adjusted by a simple configuration and means, and the change in state of the expansion / contraction member 14 can be visually enjoyed.
