Description

  TECHNICAL FIELD The present invention relates to an aroma diffusion device, and more particularly to an aroma diffusion device of a type in which a liquid containing an aroma component carried on a porous sponge is naturally evaporated.

  In recent years, there are many cases where fragrances are drifted in the living space to create an environment where you can relax your mind, relieve stress, and bring healing and calmness to your heart. A method of transpiration of the aroma using an aroma diffuser using ultrasonic vibration as a means to make the aroma float in the living space (see, for example, Patent Document 1), or diffusion of aroma components of the aroma liquid using a chemical heat source (For example, refer to patent document 2), a method for releasing the fragrance into the living space by using a humidifier or a lamp, the aromatic liquid stored in the container is sucked up by a core made of cloth or the like to be released spontaneously Methods, etc. are known.

  However, the device proposed in Patent Document 1 requires an apparatus for causing ultrasonic vibration to act on the flavor component, and the device proposed in Patent Document 2 is a chemical heat source or the heat of this heat source. An apparatus for heating the aroma liquid is required. Furthermore, in the case of using a humidifier or a lamp, a power source called a humidifier or a heat source called a lamp is required.

  On the other hand, the method of sucking up the aroma liquid stored in the container with a core made of cloth and letting it release itself spontaneously does not require a heat source or a power source, but with the conventional device that operates this method In order to maintain the initial effect over a long period of about one month, it is necessary to store a large amount of aroma liquid in a relatively large container, which restricts the place for placing the appliance from the viewpoint of the interior etc. It was easy to receive it. In addition, there is a concern that the container may fall down and the aroma liquid may leak out.

  The present invention has been made in view of the above situation, and it is necessary to use ultrasonic vibration or a heat source on the basis of adopting a porous sponge as a carrier of a liquid containing an aroma component. Furthermore, it is another object of the present invention to provide an aroma diffusion device which is less subject to the restriction of the place and does not cause the leakage of the liquid containing the aroma component.

  Also, according to the present invention, when the slow release action of the aroma component from the sponge disappears, the appearance of the sponge changes accordingly and the aroma diffusion can be easily recognized that the slow release action of the aroma component disappears. The purpose is to provide an appliance.

  In addition, the present invention makes it possible for the sponge to exhibit particularly excellent absorbability (liquid absorption property) by the combination of the characteristics of the sponge as the carrier of the liquid containing the aromatic component and the characteristics of the liquid, At the same time, it is an object of the present invention to provide an aroma diffusion device capable of sustaining the sustained release action of the aroma component over a long period of time by utilizing the high porosity of the sponge.

  An aroma diffusion device according to the present invention is an aroma diffusion device in which a porous sponge is adopted as a carrier of a liquid containing an aroma component, and the sponge as the carrier having a continuous pore structure is provided. And so on. According to this fragrance diffusion device, by the sponge having a continuous pore structure, the amount of the liquid containing the aroma component is increased, and the action of releasing the liquid is prolonged accordingly.

  In the present invention, the case is provided with a mounting type case which can accommodate the sponge together with the sponge, and the case has a bottomed case main body having an opening and a lid capable of opening and closing the opening of the case main body. , Can be adopted. The aroma diffusion device configured in this way can be placed in various places such as an entrance, a bedside, a washroom and the like without the case where the sponge is housed being subjected to much restriction on the place. In addition, it is possible to control the sustained release rate or the sustained release amount of the liquid containing the aroma component carried by the sponge by opening and closing the lid of the case. Furthermore, it is possible to make a sponge carry a liquid only by putting a liquid in a case and containing a sponge.

  In the present invention, it is preferable that the sponge is a polyvinyl alcohol resin having a pore diameter of 10 to 200 μm and a porosity of 80 to 95%, and the liquid is a water-soluble aroma oil. Since sponges made of polyvinyl alcohol resins exhibit extremely strong hydrophilicity, when a sponge made of polyvinyl alcohol resins is combined with a water-soluble aroma oil as in this invention, the rate of absorption of water-soluble aroma oils by the sponge ( The water absorption speed is increased, and the sponge can be made to carry water-soluble aroma oil quickly and in a short time. This action is further enhanced by the fact that the pore size of the sponge is as fine as 10 to 200 μm. Moreover, in this invention, since the porosity of the sponge is specified to be 80 to 95%, the amount of the water-soluble aroma oil carried by the sponge becomes very large relative to the apparent volume of the sponge, and the sponge has a small size Even then, the sustained release action of the aroma component exerted by the sponge itself can be sustained over a long period of time. Furthermore, a sponge made of a polyvinyl alcohol resin swells in the wet state to exhibit high flexibility, but shrinks in the dry state to change into a hard sponge which does not exhibit flexibility, and the wet state and the dry state And have a characteristic that a change occurs in color tone. For this reason, it becomes possible to visually recognize from the appearance the change in the color tone hardness and size of the sponge and to easily know by visual observation whether or not the controlled release of the aroma component has disappeared.

  The present invention further comprises a container for storing the liquid to be impregnated in the sponge, and the entire amount of the liquid stored in the container is an amount that can be absorbed by the sponge in a dry state. It is possible. Adoption of this configuration eliminates the need for separately preparing a liquid containing an aromatic component such as a water-soluble aroma oil to be carried on a sponge, thereby improving usability. In particular, since the total amount of the liquid stored in the container is an amount that can be absorbed by the sponge in the dry state, excess liquid may exude from the sponge even if the entire amount of the liquid in the container is supported by the sponge There is nothing to do.

  As described above, according to the device for diffusing aroma according to the present invention, since the sponge has a continuous pore structure, the carried amount of the liquid containing the aroma component is increased, and the long-term action of releasing the liquid accordingly The effect is achieved that it is easy to In addition, in the case of the installation type case, since the porous sponge can be stored in the case in the carrier of the liquid containing the aroma component in the state of use, a person's clothes touch the sponge. There is no risk of soiling clothes and dripping liquid containing aromatic components from the sponge and contaminating the floor. Furthermore, when the polyvinyl alcohol-based resin is adopted for the sponge, when the sustained release function of the aroma component from the sponge disappears, the appearance of the sponge changes accordingly and the sustained release function of the aroma component disappears There is the convenience that it can be easily recognized visually. Furthermore, when the pore diameter and porosity of the sponge made of polyvinyl alcohol resin are defined within a certain range, the water-soluble aroma oil can be absorbed in a short time, and the sustained release action of the aroma component is also prolonged Have the advantage of becoming sustainable.

It is the outline perspective view showing the component of the instrument for aroma diffusion concerning the embodiment of the present invention. It is a schematic perspective view which illustrated a sponge. It is a front view of the sponge by a modification. It is a schematic perspective view showing a state of use.

  FIG. 1 is a schematic perspective view showing components of an aroma diffusion device according to an embodiment of the present invention. The aroma diffusion device includes a sponge 10, a mounting type case 20 capable of containing the sponge 10, and a container 30 for storing a liquid to be impregnated in the sponge 10.

  FIG. 2 is a schematic perspective view illustrating the sponge 10, and FIG. 3 is a front view of the sponge 10 according to a modification. The sponge 10 illustrated in FIG. 2 has a cubic shape. The sponge 10 has a function as a carrier of a liquid containing an aromatic component. Moreover, in the example of a figure, pattern pattern 11 is made to appear on the surface of sponge 10, and the decoration property is provided to sponge 10 by this pattern pattern. The sponge 10 is a porous body having a continuous pore structure, and the pattern 11 is a suitable method that does not block the pores opened on the surface of the sponge 10, for example, a method of multicolor molding resin foams with different colors. Appeared on the surface of the sponge 10. The shape of the sponge 10 is not limited to the cubic shape shown in FIG. 2 and, for example, even if it is a constant design circular shape in plan view as shown in FIG. It may be in the shape of a pyramid, or even a building or an animal.

  In this embodiment, a sponge made of a polyvinyl alcohol resin having a pore diameter of 10 to 200 μm and a porosity of 80 to 95% is adopted as the sponge 10. A sponge made of a polyvinyl alcohol-based resin having a pore diameter and a porosity in the above range can be obtained from Aion Co., Ltd. under the trade name "Berculin (registered trademark)", "Berculin (R) Fine", and "Ber eater". The (registered trademark) A series, the "bay router (registered trademark) D series", and the like can be suitably adopted. When the pore diameter and the porosity of the sponge 10 are defined in the above-mentioned range, the absorption efficiency and the absorption amount (carrying amount) of the liquid by the sponge 10 become very excellent.

  The sponge 10 made of polyvinyl alcohol resin exhibits extremely strong hydrophilicity. And, since the pore diameter of the sponge 10 is as fine as 10 to 200 μm, the absorption speed of the water-soluble solution (for example, water-soluble aroma oil described later) becomes very fast in combination with the above-mentioned hydrophilicity of the sponge. Therefore, only by immersing the sponge 10 in a water-soluble solution or a solution obtained by diluting a water-soluble solution with water, the liquid is rapidly absorbed by the sponge 10 and carried in a short time. In addition, when the porosity of the sponge 10 is regulated to 80 to 95%, the amount of liquid carried by the sponge becomes extremely large relative to the apparent volume of the sponge 10. Furthermore, the sponge 10 made of a polyvinyl alcohol resin swells in the wet state to exhibit high flexibility, while it shrinks in the dry state to change to a hard sponge that does not exhibit flexibility, and the wet state and the dry state. In the state, it has the characteristic that a change occurs in color tone.

  The case 20 shown in FIG. 1 has a bottomed cylindrical case main body 21 having an opening opened at the top, and a lid 25 capable of opening and closing the opening of the case main body 21. Here, the case body 21 and the lid 25 are both made of transparent glass or transparent resin. As shown in FIG. 1, when the case body 21 is fitted with the lid 25 and mounted, the internal space of the case body 21 is substantially sealed. The relative size of the case 20 and the sponge 10 described above is determined to such an extent that the sponge 10 can be accommodated in the case 20 with a sufficiently wide space around it. In this embodiment, one side of the cube-shaped sponge 10 in a dry state is about 45 mm, the inside diameter of the case body 21 is about 85 mm, and the height is about 55 mm.

  In the container 30 shown in FIG. 1, the liquid to be impregnated in the sponge 10 is stored. In this embodiment, a water-soluble aroma oil (a liquid obtained by diluting a water-soluble aroma oil with water (hereinafter the same)) is adopted as the liquid. Among water-soluble aroma oils, aqueous solutions containing citrus aromatic components such as orange peel, and aqueous solutions containing various aromatic components such as lavender, peppermint, cherry, green apple and rose are known.

  In this embodiment, the total amount of the liquid stored in the container 30 is an amount that can be absorbed by the sponge 10 in a dry state. Therefore, with the sponge 10 in a dry state, the entire amount of the liquid stored in the container 30 can be carried by one absorption operation, and by doing so, the initial holding of the liquid by the sponge 10 as a carrier The amount is fixed to an appropriate amount, and the liquid does not drip from the sponge 10.

  The container 30 for storing the liquid to be impregnated into the sponge 10 is not an essential element of the device for diffusing aroma according to the present invention. For example, a commercially available product of the water-soluble aroma oil, which is separately obtained, may be suitably adopted as a substitute for the liquid stored in the container 30. However, if the container 30 for storing the liquid to be impregnated in the sponge 10 is combined in advance with the sponge 10 and the case 20 as in this embodiment, a liquid containing an aromatic component such as a water-soluble aroma oil is separately contained. The need for preparing the device is eliminated, and the usability of the aroma diffusion device is improved accordingly.

  When the above-mentioned water-soluble aroma oil as a liquid containing an aromatic component is carried on the sponge 10, it is only necessary to put the sponge 10 in a dry state into the case body 21 and pour the water-soluble aroma oil into the case body 21. In this way, the sponge 10 in a dry state absorbs the water-soluble aroma oil, and the sponge 10 carries the water-soluble aroma oil. In this case, the absorption speed of the water-soluble aroma oil by the sponge 10 can be increased by the sponge 10 made of polyvinyl alcohol resin exhibiting extremely strong hydrophilicity and the pore diameter of the sponge 10 being as fine as 10 to 200 μm. The operation is very fast, and the operation for loading is performed quickly and in a short time. Moreover, since the porosity of the sponge 10 is regulated to 80 to 95%, the amount of the water-soluble aroma oil carried by the sponge 10 becomes very large relative to the apparent volume of the sponge 10 and is exerted by the sponge 10 itself The sustained release action of the aroma component can be sustained over a long period of time.

  FIG. 4 is a schematic perspective view showing the state of use. In order to make the living space or the like have a fragrance, the lid 25 of the case 20 is opened to open the opening 22 of the case main body 21 as illustrated. In this way, the aroma component of the water-soluble aroma oil carried by the sponge 10 is naturally released slowly into the air, and the aroma is scattered in the surrounding living space. When the lid 25 is attached to the case body 21 as shown in FIG. 1 and the opening 22 of the case body 21 is closed when not in use, sustained release of the aromatic component of the water-soluble aroma oil from the sponge 10 is suppressed. As a result, the usable period is extended.

  As described above, if the water-soluble aroma oil stored in the container 30 shown in FIG. 1 is used, the entire amount of the water-soluble aroma oil can be supported on the sponge 10, and by doing so, the initial support by the sponge 10 The amount will be the optimal amount.

  In this embodiment, the sponge 10 made of a polyvinyl alcohol resin swells in the wet state to exhibit high flexibility, but shrinks in the dry state to change to a hard sponge which does not exhibit flexibility, or It has the characteristic that a change in color tone occurs between the state and the dry state. For this reason, it becomes possible to visually recognize the change in the color, hardness, and size of the sponge 10 from the appearance by visual observation and to easily know by visual observation whether or not the controlled release of the aroma component has disappeared. Then, when the sponge 10 is cured, the color is changed, or the size is shrunk, the sponge 10 is made to carry the same kind of water-soluble aroma oil, or a liquid containing another kind of aroma component is used. By supporting the washed sponge 10, it is possible to allow various fragrances to float in the living space.

  In the aroma diffusion device of the embodiment, it is known that the action by the aroma can be continued continuously for 3 to 4 weeks with the lid 25 of the case 20 open. In addition to the entrance and the bedside, the fragrance diffusing apparatus can be widely used in a washroom, a car room and the like.

  In the above embodiment, the aroma diffusion device is constituted by the combination of the sponge 10, the container 30, and the container 30 for storing the liquid to be impregnated in the sponge 10. However, as described above, this point is the container A commercially available water-soluble aroma oil which is separately obtained by omitting 30 can be appropriately adopted as a substitute, or the case 20 and the container 30 may be omitted and only the sponge 10 may be used. In the aroma diffusion device constituted only by the sponge 10, it is possible to use the sponge 10 carrying a liquid containing an aroma component in a washroom, a kitchen sink or the like.
