In the present invention, "aromatic compound" refers to a compound that can be evaporated to produce fragrance, medicinal properties, and the like.

Hereinafter, specific embodiments of the present invention will be described in more detail.

1 is a view schematically showing a unit cell of a fragrance compound emitting device according to an embodiment. A plurality of unit cells of FIG. 1 may be configured in a regular arrangement to constitute a fragrance compound emitting device.

Referring to FIG. 1, an inner space 13 is formed in the support body 11, and a heating wire 17 is formed below the inner space 13. The inner space 13 provides a space in which the aromatic compound can be contained, and the entrance of the inner space 13 is closed while a part of the carrier 11 abuts and forms an interface. The interior space 13 can have a diameter of several micrometers to several millimeters. For example, the interior space 13 may have a diameter of 1 micrometer to 10 millimeters. At this time, since the interface of the inlet of the inner space 13 is not adhered, when the carrier 11 is deformed, the inlet of the inner space 13 may be opened apart from each other. The inner space 13 may have various forms capable of containing aromatic compounds. The inner space 13 may have, for example, a triangular pyramid, a quadrangular pyramid, a cone, or a spherical shape, but is not limited thereto.

For example, the inner space 13 forming the unit cell may form a column array or a matrix array, but is not limited thereto and may have various arrays.

The carrier 11 may be made of a rubber material. The carrier 11 may be made of, for example, natural rubber or synthetic rubber. The synthetic rubber may be made of a block copolymer, fluorine rubber, silicone rubber, polybutadiene, polyisoprene, and the like. Block copolymers are, for example, styrene-butadiene-styrene rubber (SBS rubber), styrene-ethylene-butadiene-styrene rubber (SEBS rubber), ethylene-propylene copolymer, ethylene-butene-diene copolymer, ethylene-propylene-diene Copolymers, hydrogenated styrene-butadiene copolymers. In addition, synthetic rubbers include polysiloxane, polymethacrylamide, nitrile rubber, acrylic rubber, polyethylene tetrafluoride, polybutene, polypentene butyl rubber, polymethylpentene, styrene hydrogenated polyisoprene, Hydrogenated polybutadiene, and the like. The silicone rubber may include, for example, polydimethylsiloxane (PDMS).

Rubber has a different molecular behavior depending on the temperature. The rubber has a glass state below the glass transition temperature (Tg), but when the glass transition temperature is higher than the temperature, the rubber becomes a rubbery state, and adhesion between the interfaces is improved. Therefore, the sealing ability is improved at a glass transition temperature or higher, and thus can be used as a stopper for holding liquid. That is, the rubber carrier 11 has a rubbery elastic modulus at room temperature higher than the glass transition temperature, thereby maintaining an excellent sealing state at the entrance of the inner space 13. However, when the current 11 flows through the heating wire 17 and the support member 11 is heated, the rubber further goes from a soft state to a flow state. Then, the bag at the entrance of the inner space 13 is weakened, and as a result, the aromatic compound 15 in the inner space 13 is released. On the other hand, when the current in the heating wire 17 is cut off, the temperature of the supporting body 11 decreases, so that the rubber of the supporting body 11 flows back to a soft state and elasticity occurs, so that the entrance of the inner space 13 is closed again. do. Therefore, by changing the rubber molecular behavior of the carrier 11 from the soft state to the flowing state by turning on and off the current generating heat in the heating wire 17, the aromatic compound 15 is opened and closed by opening the inside space 13 The on and off of the emission can be switched.

The heating wire 17 may be formed of a heating material that generates heat by electric resistance when a current flows. The heating wire 17 may be formed of an exothermic metal alloy, for example, one or more of Co, Cr, and Mo and an alloy of Ni. For example, the heating wire 17 may be formed of a nichrome wire. The diameter of the heating wire 17 may vary depending on the size of the inner space 13. For example, the hot wire 17 may have a diameter in the range of about 1-100 μm.

The heating wire 17 may be positioned at a suitable distance from each interior space 13 so as to deform the carrier 11 and apply heat to open the entrance of the interior space 13. The hot wire 17 may include a hot wire in the first direction, and may further include a hot wire in the second direction. The heating wires in the first direction and the second direction may cross each other. When both the heating wire in the first direction and the heating wire in the second direction are present, the carrier 11 cannot be deformed by heat generated in the heating wire in one direction, and the carrier 11 only when heat is generated in both of the heating wires in both directions ), The heat generated from the heating wire can be controlled to deform it. Alternatively, the heat generated in the hot wire may be adjusted so that the carrier 11 can be deformed only by the heat generated in the hot wire in one direction. Therefore, it is possible to stop the emission of the aromatic compound by applying a current to the heating wire 17 to open the inner space 13 to release the aromatic compound, and breaking the applied current to close the inner space 13.

In FIG. 1, the heating wire 17 is located under the interior space 23, but, alternatively, for example, the heating wire 17 may be located between the interior space 23 and the interior space 23. As such, the arrangement of the heating wire 17 can be appropriately changed to open the entrance of the interior space 13.

Meanwhile, the surface of the heating wire 17 may have an uneven structure. 2 is a schematic cross-sectional view of the hot wire 17 of the uneven structure. Referring to Fig. 2, the heating wire 17 is composed of an inner 17a and an outer 17b, and the outer 17b has an uneven structure. The uneven structure may have, for example, a diameter in the range of about 0.01-10 μm and a height in the range of about 0.1-10 μm. By having the concave-convex structure of the outside 17b of the heating wire 17, the heating area of the heating wire 17 is increased, so that the heating and heating efficiency of the support 11 can be increased.

The concavo-convex structure of the heating wire 17 can be manufactured using a method such as mechanical machining, laser surface texturing, or etching.

For example, the method of forming the unevenness of the heating wire by RF plasma texturing is as follows. The heating wire is placed vertically at regular intervals on the cathode plate in the RF plasma chamber. Argon, hydrogen or nitrogen can be used as the plasma gas. The temperature of the chamber can be maintained at 800-1000 ° C. Ion bombardment in the plasma can affect the formation of irregularities on the surface of the heating wire. The uneven structure of the surface can be adjusted according to the treatment time, power, pressure, gas used, and the number of repetitive treatments of the plasma.

3 is an uneven structure formed on the surface of MP35N (35% Co, 35% Ni, 20% Cr, 10% Mo, weight ratio%) nichrome wire using RF argon plasma. As shown in Fig. 3, an uneven structure formed like a brush is formed on the surface of the nichrome wire by RF plasma treatment. The length of the brush can be adjusted, for example, by the number of plasma treatments. Due to the presence of the concavo-convex structure, the heating area of the heating wire is increased, so that the heating effect is improved, and thus the temperature increase effect of the surroundings can be improved.

4 is a view schematically showing a unit cell of a fragrance compound emitting device according to another embodiment. A plurality of unit cells of FIG. 4 may be configured in a regular arrangement to constitute a fragrance compound emitting device.

Referring to FIG. 4, a plurality of inner spaces 23 are formed in the substrate 21, and a heating wire 17 is formed below the inner spaces 23. The inner space 23 provides a space in which the fragrance compound can be contained. The interior space 23 can have a diameter of several micrometers to several millimeters. For example, the interior space 23 may have a diameter of 1 micrometer to 10 millimeters. A capping film 24 is formed on the surface of the substrate 21, and a part of the capping film 24 is in contact, so that the entrance of the inner space 23 is closed. At this time, since portions of the capping layer 24 are not in contact with each other, the force may be separated from each other, and the entrance of the inner space 23 may be opened. The inner space 23 may have various forms capable of containing an aromatic compound. The inner space 23 may have, for example, a triangular pyramid, a quadrangular pyramid, a cone, or a spherical shape, but is not limited thereto. In addition, the inner space 13 forming the unit cell may form a column array or a matrix array, but is not limited thereto and may have various arrays.

The substrate 21 may be formed of various materials such as plastic, metal, and silicon. In this case, the inner space 23 in the substrate 21 may be formed by, for example, a microelectromechanical systems (MEMS) process. Alternatively, the substrate 21 may be made of an anodic aluminum oxide substrate. The inner space 23 in the anodized aluminum substrate may be formed by an anodizing process. The plurality of interior spaces 23 may form a matrix arrangement, for example.

The capping film 24 may be made of a rubber material. The capping film 24 may be made of, for example, natural rubber or synthetic rubber. Synthetic rubber may be made of a block copolymer, fluorine rubber, isoprene, silicone rubber, and the like. The block copolymer may include, for example, styrene-butadiene-styrene rubber (SBS rubber) and styrene-ethylene-butadiene-styrene rubber (SEBS rubber). The silicone rubber may include, for example, polydimethylsiloxane (PDMS).

The heating wire 17 may use a heating wire as described in the embodiment of FIG. 1, that is, the heating wire 17 may be formed of a heating material that generates heat by electric resistance when a current is passed. The heating wire 17 may be formed of an exothermic metal alloy, for example, one or more of Co, Cr, and Mo and Ni. For example, the heating wire 17 may be formed of a nichrome wire. The diameter of the heating wire 17 may vary depending on the size of the inner space 13. For example, the hot wire 17 may have a diameter in the range of about 1-100 μm.

The hot wire 17 is to be positioned at an appropriate distance from the capping film 24 of each inner space 13 to deform the capping film 24 to apply heat to open the inlet of the inner space 13. You can. The hot wire 17 may include a hot wire in the first direction, and may further include a hot wire in the second direction. The heating wires in the first direction and the second direction may cross each other. When both the first direction and the second direction heat rays are present, the heat generated in one direction does not deform the capping film 24, and the capping film 24 only occurs when heat is generated in both directions. ), The heat generated from the heating wire can be controlled to deform it. Alternatively, the heat generated in the hot wire may be adjusted so that the capping film 24 can be deformed only with the heat generated in the hot wire in one direction. Therefore, it is possible to stop the emission of the aromatic compound by applying a current to the heating wire 17 to open the inner space 13 to release the aromatic compound, and breaking the applied current to close the inner space 13.

In FIG. 4, the heating wire 17 is located under the interior space 23, but, alternatively, for example, the heating wire 17 may be located between the interior space 23 and the interior space 23. In this way, the arrangement of the heating wire 17 can be appropriately changed.

Meanwhile, the surface of the heating wire 17 may have an uneven structure as described above. The outer 17b of the heating wire 17 has an uneven structure, so that the heating area of the heating wire 17 is increased, so that the heating and heating efficiency of the capping film 24 can be increased.

The capping film 24 has elasticity in a soft state at room temperature, thereby maintaining an excellent sealing state at the entrance of the inner space 23. When a current flows through the heating wire 27, the heating wire 27 is heated to heat the substrate 21 and the capping film 24. When the capping film 24 is heated, the rubber further goes from a soft state to a flowing state, and the sealing of the entrance of the inner space 23 becomes weak, and as a result, the aromatic compound 25 in the inner space 23 is discharged out. When the current in the heating wire 27 is cut off, the temperature of the substrate 21 and the capping film 24 decreases, so that the rubber of the capping film 24 flows back to a soft state and elasticity is generated, so that the entrance of the interior space 23 is generated. Will close. Therefore, the on / off of the emission of the fragrance compound 25 can be switched on and off by opening and closing the inlet of the inner space 23 by turning on / off the current supply that generates heat to the heating wire 27.

In the above embodiments, a conical or cylindrical inner space is shown, but the shape of the inner space is not limited thereto and may have various shapes. In addition, the position and shape of the heating wire and electrode are also not limited to the above embodiments, and may be appropriately changed within a range capable of opening and closing the entrance of the interior space by modifying the carrier or capping film.

5 is a plan view schematically showing the arrangement of the interior space and the heating wire of the fragrance compound emitting device according to one embodiment. In FIG. 5, the inner space 3 is arranged in a matrix form, and the heating wires 7 are arranged in the column direction. Thus, for example, when heating the heating wire 3 of column III, the inlets of all the internal spaces 3 belonging to the column III are opened and the aromatic compound therein can be released. On the other hand, it is possible to simultaneously select and open a plurality of rows to simultaneously release the aromatic compounds in the interior space 3 of two or more rows. For example, by heating the heat rays 7 of rows II and IV at the same time, the inner space 3 belonging to rows II and IV can be opened simultaneously to emit different scents and mix to create a new scent.

6 is a plan view schematically showing the arrangement of the inner space and the heating wire of the fragrance compound emitting device according to another embodiment. In FIG. 6, the inner space 3 is arranged in a matrix form, and the column lines 7 are arranged in the row direction 7a 'and the column direction 7b'.

By selecting a row and a column and supplying current to the heating wire 7, a fragrance compound can be selected and released. At this time, the current of the heating wire 7 can be adjusted so that the inlet of the internal space 3 can be opened only when current is supplied to both the heating wires of the row and the column to generate heat. That is, if only the row or column only the heating wire (7) generates heat, the amount of heat is small, so the inner space (3) belonging to the row or column is not opened, and only when both the row and column heating wire (7) generates heat, the inner space (3) The current flowing through the row and column heat lines can be adjusted to open.

For example, by supplying electric current to the heating wires 7 in the C and II rows, only the aromatic compounds contained in the interior space 3 where these heating wires intersect can be released. In this case, the other inner spaces 3 of the rows C and II are not opened because the heat value of the heating wire does not exceed a threshold value that can open the inner space, so that the aromatic compound therein is not released.

On the other hand, it is possible to simultaneously release two or more aromatic compounds by simultaneously selecting and opening a plurality of interior spaces 3. For example, to select the two inner spaces (3) at the locations of (C, II) and (A, IV), current can be applied simultaneously to the heating wires of rows C, II, A, and IV. have. By opening two or more interior spaces 3 simultaneously and emitting and mixing different scents, new scents can be made.

On the other hand, just as the inner space 3 is selected in units of columns in the aromatic compound emitting device of FIG. 5, only the column or row can be selected in the aromatic compound emitting device of FIG. 6 to release the aromatic compound in the inner space 3 belonging thereto. So that the applied current of the heating wire can be adjusted.

5 and 6, the internal space 3 forms a 4 * 5 arrangement, but the number and arrangement of the internal spaces 3 can be variously modified.
