[0013] <1. Scent Providing Device> First, the scent providing device 1 according to the present embodiment will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view showing an example of the scent providing device 1 according to the present embodiment. FIG. 2 is a cross-sectional perspective view showing an example of the scent providing device 1 according to the present embodiment. FIG. 3 is an exploded perspective view showing an example of the scent providing device 1 according to the present embodiment. Hereinafter, in the scent providing device 1, the side where the discharge port 110 of the lid 100 is disposed is referred to as the front end side.

[0014] As shown in FIGS. 1 to 3, the scent providing device 1 according to the present embodiment includes a lid 100, a fragrance holding member 200, an air pump 300, a battery 400, a rotation mechanism 500, a chassis 600, a switch 700, and a substrate 800.

[0015] The lid 100 is a member that separates the fragrance holding member 200 from the outside. The lid 100 has, for example, a cylindrical shape with an open rear end side as shown in FIGS. 1 to 3. A discharge port 110 through which air containing the vaporized fragrance sent from the fragrance holding member 200 is discharged is provided on the front end side of the lid 100. The discharge port 110 is provided so as to communicate with the tip of the ventilation passage 220 to which air is supplied among the plurality of ventilation passages 220 provided in the fragrance holding member 200. The inner diameter of the discharge port 110 may be larger than the inner diameter of the ventilation passage 220.

[0016] The fragrance holding member 200 is a member that holds the fragrance. The fragrance holding member 200 has, for example, a hollow cylindrical shape as shown in FIGS. 2 and 3. As shown in FIG. 2, a ventilation passage 220 through which air supplied from an air pump 300, which is an example of a wind power source according to the present disclosure, passes is provided so as to penetrate the fragrance holding member 200. Further, the fragrance holding member 200 is provided with a holding space that branches off from the ventilation passage 220 and holds the fragrance. The fragrance may be held in the ventilation passage 220, and in that case, it is held in a state of adhering to the inner surface of the ventilation passage 220. Also, in the holding space, the fragrance may be held in a state of adhering to the inner surface of the holding space, or may be held in a state of filling the holding space. Specifically, the fragrance may be essential oil or essential oil diluted with ethanol or the like. One or a plurality of pairs of the ventilation passage 220 and the holding space may be provided. Hereinafter, as an example, an example in which a plurality of pairs of the ventilation passage 220 and the holding space are provided will be described. Also, hereinafter, an example in which the fragrance is held in the ventilation passage 220 will be mainly described.

[0017] The plurality of ventilation passages 220 are provided, for example, at equal intervals on the circumference around the central axis of the fragrance holding member 200 and are provided linearly from the rear end side to the front end side. The air supplied from the air pump 300 flows into the rear end portion of the ventilation passage 220 through the flow path 610 of the chassis 600 and is discharged from the front end portion. Thereby, a flow of air from the rear end side to the front end side of the ventilation passage 220 is generated. The vaporized components of the fragrance held in the ventilation passage 220 are sent to the front end side of the ventilation passage 220 by the flow of air generated in the ventilation passage 220. Also, the non-vaporized portion of the fragrance held in the holding space does not flow out from the holding space to the ventilation passage 220, but the vaporized components of the fragrance flow out to the ventilation passage 220 through the branch portion between the holding space and the ventilation passage 220 by the flow of air generated in the ventilation passage 220 and are sent to the front end side of the ventilation passage 220. Then, the vaporized components of the fragrance sent to the front end side of the ventilation passage 220 are discharged from the discharge port 110 of the lid 100.

[0018] Examples of the materials constituting the ventilation passage 220 and the holding space include resins such as acrylic resin, urethane resin, ABS resin, PEEK (polyetheretherketone), POM (polyacetal), silicone resin, fluororesin, olefin polymer resin, or polyimide resin, metals such as stainless steel, or glass. Specifically, the materials constituting the ventilation passage 220 and the holding space can be selected in consideration of chemical resistance, weather resistance, strength, etc. As an example, the inner diameters of the ventilation passage 220 and the holding space can be set to values smaller than 1 mm. The ventilation passage 220 and the holding space, which are microchannels having such a small inner diameter, can be manufactured, for example, by a laminated manufacturing method using a 3D printer.

[0019] The smaller the inner diameter of the ventilation passage 220, the more easily the generation of turbulent flow of the fluid in the ventilation passage 220 is suppressed, and the flow of the fluid is more likely to be laminar. Also, when the output of the air pump 300 is constant, the smaller the inner diameter of the ventilation passage 220, the faster the air velocity in the ventilation passage 220. Thereby, in the fragrance providing device 1 according to the present embodiment, the straightness of the air containing the vaporized components of the fragrance discharged from the discharge port 110 is improved. Therefore, by discharging the air containing the vaporized components of the fragrance toward the user of the fragrance providing device 1, the user can receive the provision of the fragrance without affecting the surroundings of the user.

[0020] Also, the smaller the inner diameter of the ventilation passage 220, the larger the ratio of the region where the fragrance is held to the region through which the air passes in the cross section of the ventilation passage 220. Therefore, the ratio of the fragrance contained in the air discharged from the discharge port 110 due to the air flow generated in the ventilation passage 220 increases. Thereby, the fragrance can be provided to the user more reliably. Also, by reducing the inner diameter of the ventilation passage 220 or the holding space, the dimensions of the entire device can be reduced, so the weight of the entire device can be reduced. Therefore, the portability of the fragrance providing device 1 can be facilitated. Details of the configuration of the ventilation passage 220 and the holding space of the fragrance holding member 200 will be described later.

[0021] The air pump 300 is an example of a wind power source according to the present disclosure. The air pump 300 supplies air to some of the plurality of ventilation passages 220 of the fragrance holding member 200 through, for example, the flow path 610. The air pump 300 is electrically connected to the battery 400 through, for example, the substrate 800 and is driven by the electric power supplied from the battery 400. Specifically, the air pump 300 includes a diaphragm to which a piezoelectric element is attached, and blows air by deforming the diaphragm by applying an alternating current to the piezoelectric element. Note that the air blowing form of the air pump 300 is not limited to such an example, and may be, for example, a fin type or a cylinder type. Further, the air pump 300 may be a manual type, and in that case, the battery 400, the switch 700, and the substrate 800 may be omitted from the configuration of the fragrance providing device 1.

[0022] The battery 400 stores electric power for operating the air pump 300. The battery 400 may be a primary battery that can only discharge, or may be a secondary battery that can be charged.

[0023] The rotation mechanism 500 has a function of making it possible to switch the ventilation passage 220 to which air is supplied among the plurality of ventilation passages 220 of the fragrance holding member 200. Specifically, the rotation mechanism 500 communicates with some of the plurality of ventilation passages 220, and a member provided with a flow path for introducing the air supplied from the air pump 300 into some of the ventilation passages 220 and the fragrance holding member 200 are relatively rotatable so that the ventilation passage 220 communicating with the flow path is switched. More specifically, the rotation mechanism 500 makes the chassis 600 and the fragrance holding member 200 relatively rotatable so that the ventilation passage 220 communicating with the flow path 610 of the chassis 600 is switched. Note that in FIG. 2, the flow path 610 of the chassis 600 is shown as the air flow path between the air pump 300 and the ventilation passage 220, but other flow paths may be interposed between the flow path 610 of the chassis 600 and the ventilation passage 220. In that case, the member provided with the other flow path and the fragrance holding member 200 may be configured to be relatively rotatable by the rotation mechanism 500.

[0024] An air pump 300, a battery 400, a rotation mechanism 500, and a substrate 800 are disposed on the chassis 600. Also, wiring for electrically connecting between components may be provided on the chassis 600 as needed.

[0025] The switch 700 is provided on the substrate 800 to switch the driving state of the air pump 300. The substrate 800 is electrically connected to the battery 400. For example, when the switch 700 is pressed by the user, power is supplied to a drive circuit for driving the air pump 300 mounted on the substrate 800. Thereby, the driving state of the air pump 300 is switched according to the pressed state of the switch 700 by the user.

[0026] FIG. 4 is a system block diagram showing an example of the fragrance providing device 1 according to the present embodiment. As shown in FIG. 4, the battery 400 and the substrate 800 are electrically connected. Then, when the switch 700 is pressed, power is supplied to a drive circuit for driving the air pump 300 mounted on the substrate 800, and the air pump 300 is driven. Thereby, the air pump 300 starts blowing air, and the air supplied from the air pump 300 is sent to the ventilation passage 220 of the fragrance holding member 200. Then, the vaporized components of the fragrance held in the ventilation passage 220 and the holding space of the fragrance holding member 200 are discharged to the outside from the discharge port 110 of the lid 100. The switching of the ventilation passage 220 into which air is introduced among the plurality of ventilation passages 220 of the fragrance holding member 200 by the rotation mechanism 500 is performed manually.

[0027] In this specification, as described with reference to FIG. 4, the fragrance providing device 1 in which the switching by the rotation mechanism 500 of the ventilation passage 220 into which air is introduced is manually performed will be mainly described. However, the form of switching by the rotation mechanism 500 is not limited to such an example. For example, the rotation mechanism 500 may be driven by a motor. The fragrance providing device 1a according to such another embodiment includes a motor 310 that drives the rotation mechanism 500 and a switch 710 that switches the energization to a drive circuit for driving the motor 310 mounted on the substrate 800. According to the fragrance providing device 1a, for example, as shown in FIG. 5, when the switch 710 is pressed, the drive circuit for driving the motor 310 mounted on the substrate 800 is energized, and the motor 310 is driven. Thereby, the rotation mechanism 500 is driven by the motor 310, and the switching by the rotation mechanism 500 of the ventilation passage 220 into which air is introduced among the plurality of ventilation passages 220 of the fragrance holding member 200 is performed.

[0028] <2. Fragrance holding member> [2-1. First example] Subsequently, with reference to FIGS. 6 to 8, the fragrance holding member 201 according to the first example will be described. FIG. 6 is a perspective view showing an example of the configuration of the fragrance holding member 201 according to the first example. FIG. 7 is a plan view and a side view showing an example of the configuration of the fragrance holding member 201 according to the first example. As shown in FIGS. 6 and 7, the fragrance holding member 201 includes a ventilation passage 220, a holding space 230, and a locking groove 250.

[0029] The ventilation passage 220 is provided to penetrate the fragrance holding member 201, and the air supplied from the air pump 300 passes through the ventilation passage 220. The air supplied from the air pump 300 flows in from the inlet 222 which is one end of the ventilation passage 220, and is discharged from the outlet 224 which is the other end of the ventilation passage 220. Also, fragrance may be held in the ventilation passage 220. As shown in FIGS. 6 and 7 for example, a plurality of ventilation passages 220 are linearly provided in the axial direction of the fragrance holding member 200, and the inlet 222 and the outlet 224 are formed on the rear end surface and the front end surface of the fragrance holding member 200 respectively. Also, the ventilation passage 220 may be provided on the circumference around the central axis of the fragrance holding member 200. In that case, the rotation mechanism 500 is configured to be able to rotate the fragrance holding member 200 around the central axis of the fragrance holding member 200 with respect to the chassis 600. Thereby, by rotating the fragrance holding member 200, the ventilation passage 220 communicating with the flow path 610 of the chassis 600 located on the rear end side of the fragrance holding member 200 can be switched.

[0030] Note that the path of the ventilation passage 220 does not have to be linear, and may have a curved shape for example. Also, the inlet 222 or the outlet 224 may be formed on the outer peripheral surface of the fragrance holding member 200. In that case, the position of the flow path 610 of the chassis 600 or the position of the discharge port 110 of the lid 100 is set to a position that can communicate with the inlet 222 or the outlet 224 respectively.

[0031] The holding space 230 branches off from the ventilation passage 220 and holds the fragrance. The holding space 230 is provided for each of the plurality of ventilation passages 220, for example, as shown in FIGS. 6 and 7. When the fragrance is held in the ventilation passage 220, the same type of fragrance as that held in the ventilation passage 220 communicating with the holding space 230 is held in the holding space 230. Note that two or more holding spaces 230 may be provided for one ventilation passage 220. The holding space 230 branches off from a branching portion 240 located on the outlet 224 side of the ventilation passage 220 and extends toward the inlet 222 side from the branching portion 240, for example, as shown in FIGS. 6 and 7. The holding space 230 communicates with the ventilation passage 220 at the branching portion 240. Also, the end portion on the inlet 222 side of the holding space 230 is separated from the outside by a sealing member 232 provided on the rear end surface of the fragrance holding member 200.

[0032] The holding space 230 is formed, for example, by forming a through passage from the rear end surface of the fragrance holding member 200 to the branching portion 240 and then sealing the opening on the rear end surface side of the fragrance holding member 200 of the through passage with the sealing member 232. Thereby, the holding space 230 communicating with the ventilation passage 220 and separated from the outside is formed. The sealing member 232 may be provided for each of the holding spaces 230, for example, as shown in FIGS. 6 and 7. Note that the sealing member 232 is merely an example of a configuration for realizing the function of separating the holding space 230 from the outside. For example, the function may also be realized by covering the rear end surface of the fragrance holding member 200 with a sheet having an opening at a position corresponding to the position of each inlet 222 of the ventilation passage 220 and sealing the opening of the through passage formed in the process of forming the holding space 230 with the sheet.

[0033] When air is sent to the ventilation passage 220, an air flow from the rear end side to the front end side of the ventilation passage 220 is generated. The vaporized components of the fragrance held in the ventilation passage 220 are sent to the front end side of the ventilation passage 220 by the air flow generated in the ventilation passage 220. Further, the vaporized components of the fragrance held in the holding space 230 flow out into the ventilation passage 220 through the branch portion 240 between the holding space 230 and the ventilation passage 220 by the air flow generated in the ventilation passage 220, and are sent to the front end side of the ventilation passage 220. Then, the vaporized components of the fragrance sent to the front end side of the ventilation passage 220 are discharged from the discharge port 110 of the lid 100.

[0034] Here, each of a plurality of pairs of the ventilation passage 220 and the holding space 230 may hold different types of fragrances. In that case, by switching the ventilation passage 220 communicating with the flow path 610 of the chassis 600, the fragrance provided by the fragrance providing device 1 can be switched. Note that each of a plurality of pairs of the ventilation passage 220 and the holding space 230 may hold the same type of fragrance. For example, by holding the fragrances used more frequently in a larger number of pairs of the ventilation passage 220 and the holding space 230, the duration of each fragrance can be appropriately set according to the usage frequency of each fragrance.

[0035] If the holding space 230 that branches from the ventilation passage 220 and holds the fragrance is not provided in the fragrance holding member, the fragrance may be held only in the ventilation passage 220. On the other hand, in the fragrance providing device 1 according to the present embodiment, in addition to the ventilation passage 220 in which an air flow for discharging the vaporized components from the fragrance to the outside is generated, the fragrance can also be held in the holding space 230 which is a space different from the ventilation passage 220. Thereby, the amount of the fragrance that can be held by the entire fragrance holding member 201 can be increased. Therefore, by providing the holding space 230 in the fragrance holding member 201, it is possible to improve the persistence of the fragrance while avoiding an increase in the size of the device.

[0036] The fragrance is held, for example, in a state of adhering to the inner surfaces of the ventilation passage 220 and the holding space 230. Therefore, the larger the inner surface area of the ventilation passage 220 or the holding space 230, the larger the amount of fragrance that the ventilation passage 220 or the holding space 230 can hold. Thus, by increasing the inner surface area of the holding space 230 as compared with the ventilation passage 220, the amount of fragrance that can be held in the holding space 230 can be increased as compared with the ventilation passage 220. In such a case, even if the fragrance is not held in the ventilation passage 220, the amount of fragrance that can be held by the entire fragrance holding member 201 can be increased.

[0037] The holding space 230 may have a curved shape. Thereby, the path length of the holding space 230 can be increased as compared with the case where the holding space 230 is provided linearly. Therefore, since the amount of fragrance that the holding space 230 can hold can be increased, the persistence of the fragrance can be further improved. FIG. 8 is a conceptual diagram for explaining an example of the configuration of the fragrance holding member 201 according to the first example. As shown in FIG. 8, in the first example, the holding space 230 branches off from a branch portion 240 of the ventilation passage 220 that is provided linearly from the inlet 222 to the outlet 224.

[0038] Specifically, the holding space 230 according to the first example has a spiral shape as shown in FIG. 8. For example, while drawing a spiral, the holding space 230 extends from the branch portion 240 toward the inlet 222 side along the direction in which the ventilation passage 220 extends. In the first example, since the holding space 230 has a spiral shape, it does not have a bent portion where stress is likely to concentrate. Therefore, while improving the strength of the fragrance holding member 200, the persistence of the fragrance can be improved.

[0039] In the first example, as shown in FIGS. 6 and 7, the helical twist axis of the holding space 230 is located outside the inner peripheral portion and inside the outer peripheral portion of the fragrance holding member 201. Further, the holding space 230 is located, for example, between adjacent ventilation passages 220. Thus, by providing the helical holding space 230 such that the twist axis is located outside the inner peripheral portion and inside the outer peripheral portion of the fragrance holding member 201, it is possible to effectively utilize the space between each ventilation passage 220 while increasing the amount of fragrance that can be held.

[0040] The locking groove 250 is provided along the axial direction of the fragrance holding member 201 on the outer peripheral portion of the rear end side of the fragrance holding member 201 as shown in FIGS. 6 and 7 in order to enable relative rotation between the chassis 600 and the fragrance holding member 201 in the rotation mechanism 500. When a holding member that holds the fragrance holding member 201 and rotates integrally with the fragrance holding member 201 is used in the relative rotation between the chassis 600 and the fragrance holding member 201, a locking projection is provided on the holding member. In a state where the fragrance holding member 201 is held by the holding member, the locking projection of the holding seat is fitted into the locking groove 250 of the fragrance holding member 201, thereby preventing the fragrance holding member 201 from rotating with respect to the holding member.

[0041] [2-2. Second Example] As described above, an example of the fragrance holding member provided with the helical holding space has been described, but the arrangement of the holding space in the fragrance holding member is not limited to such an example. Hereinafter, a second example in which the arrangement of the holding space in the fragrance holding member is different from that of the first example will be described with reference to FIGS. 9 and 10.

[0042] FIG. 9 is a perspective view showing an example of the configuration of the fragrance holding member 202 according to the second example. FIG. 10 is a cross-sectional view and a side view showing an example of the configuration of the fragrance holding member 202 according to the second example. Specifically, FIG. 10 shows a cross-sectional view of the fragrance holding member 202 in a cross-section passing through the central axis of the fragrance holding member 202 and a side view of the fragrance holding member 202 viewed in the direction of the central axis. As shown in FIGS. 9 and 10, the fragrance holding member 202 includes a ventilation passage 220, a holding space 230a, and a locking groove 250. The holding space 230a according to the second example has a spiral shape, similar to the first example, and extends from the branch portion 240 toward the inlet 222 side along the direction in which the ventilation passage 220 extends while drawing a spiral. On the other hand, in the second example, compared with the first example, the position of the spiral twist axis of the holding space 230a in the fragrance holding member 202 is different.

[0043] In the second example, as shown in FIGS. 9 and 10, the spiral twist axis of the holding space 230a is located inside the inner peripheral portion of the fragrance holding member 202. Specifically, the spiral twist axis of the holding space 230a substantially coincides with the central axis of the fragrance holding member 202. Therefore, the holding space 230a extends along the direction in which the ventilation passage 220 extends while drawing a spiral in the circumferential direction of the fragrance holding member 202. For example, the holding spaces 230a communicating with the respective ventilation passages 220 may be configured to draw a spiral in an adjacent state to each other. Thus, by providing the spiral-shaped holding space 230a such that the twist axis is located inside the inner peripheral portion of the fragrance holding member 202, it is possible to effectively utilize the space near the inner peripheral portion or the outer peripheral portion of the hollow cylindrical fragrance holding member 200 and increase the amount of fragrance that can be held.

[0044] In the above, an example in which the holding space has a curved shape has been described. However, the shape of the holding space is not limited to such an example. For example, the holding space may be provided linearly. FIG. 11 is a conceptual diagram for explaining an example of the configuration of a fragrance holding member according to another embodiment. In the example shown in FIG. 11, the holding space 230b branches from the branch portion 240 of the ventilation passage 220 provided linearly from the inlet 222 to the outlet 224 and is provided linearly. Further, as shown in FIG. 11, the holding space 230b in such an example has an increased diameter on the inlet 222 side from the branch portion 240. Thereby, the inner surface area of the holding space 230b can be increased as compared with the case where the holding space 230b has a shape that does not increase in diameter after branching at the branch portion 240. Thereby, since the amount of fragrance that the holding space 230b can hold can be increased, the persistence of the fragrance can be further improved.

[0045] [2-3. Effect] Subsequently, the effect of improving the persistence of the fragrance according to the present embodiment will be described. FIG. 12 is an explanatory diagram for explaining the persistence of the fragrance in the present embodiment. The comparative example in FIG. 12 shows an example in which, unlike the above-described first and second examples, a fragrance holding member that does not include a holding space branching from the ventilation passage and holds the fragrance only in the ventilation passage is used. In FIG. 12, the test results of the intensity of the fragrance provided to the outside of the device by the fragrance providing device at each time after the start of use of the fragrance holding member for the first example, the second example, and the comparative example are shown. As shown in FIG. 12, the intensity of the fragrance provided to the outside of the device at each time in the first example and the second example is higher than that of the comparative example. In other words, the amount of decrease in the intensity of the fragrance per unit time in the first example and the second example is smaller than that of the comparative example. From this result, it was confirmed that the persistence of the fragrance can be improved according to the present embodiment.

[0046] <3. Modification>[ Subsequently, various modifications according to the present disclosure will be described.

[0047] [3-1. First Modification] First, with reference to FIG. 13, a first modification example capable of further improving the straightness of the air discharged to the outside of the device containing the vaporized components of the fragrance will be described.

[0048] FIG. 13 is an explanatory diagram showing an example of the configuration of the ventilation passage 220a according to the first modification example. As shown in FIG. 13, a tapered portion 221 that tapers as it approaches the outlet 224 is provided on the outlet 224 side of the ventilation passage 220a according to the first modification example. Thereby, the air sent from the ventilation passage 220a to the outlet 224 can be constricted. Therefore, the diffusion of the air discharged from the outlet 224 can be suppressed. Thus, the straightness of the air discharged to the outside of the device containing the vaporized components of the fragrance can be further improved. Note that the position where the diameter reduction of the ventilation passage 220a starts by the tapered portion 221 and the taper angle of the tapered portion 221 can be appropriately set according to the dimensions of the ventilation passage 220a, the pressure of the air supplied to the ventilation passage 220a, and the like. Further, the same effect can also be obtained by providing a tapered portion that tapers as it approaches the tip side at the discharge port 110 of the lid 100 communicating with the outlet 224.

[0049] [3-2. Second Modification Example] Subsequently, with reference to FIG. 14, a second modification example having another configuration for obtaining the same effect as the first modification example will be described. FIG. 14 is an explanatory diagram showing an example of the configuration of the ventilation passage 220b according to the second modification example. As shown in FIG. 14, a spiral groove 223 is provided on the surface inside the ventilation passage 220b according to the second modification example. Thereby, a swirling motion is imparted to the air discharged from the outlet 224, and the straightness can be improved by the gyroscopic effect. Thus, the straightness of the air discharged to the outside of the device containing the vaporized components of the fragrance can be further improved. Note that the number or cross-sectional shape of the groove 223 is not limited to the example shown in FIG. 14, and other numbers or other cross-sectional shapes may be used.

[0050] [3-3. Third Modification Example] Next, with reference to FIG. 15, a third modification example capable of increasing the amount of fragrance that can be held by the fragrance holding member 200 will be described. FIG. 15 is an explanatory diagram showing an example of the configuration of the ventilation passage 220c according to the third modification example. As shown in FIG. 15, a surface increasing portion 225 for increasing the surface within the ventilation passage 220c is provided in the ventilation passage 220c according to the third modification example. The surface increasing portion 225 may have, for example, a rotationally symmetric shape around the central axis of the ventilation passage 220c. Specifically, as shown in FIG. 15, the surface increasing portion 225 may be composed of two cylinders that intersect the central axis of the ventilation passage 220c and are perpendicular to each other. Thereby, by holding the fragrance in a state where it adheres to the surface of the surface increasing portion 225, the amount of fragrance that can be held by the fragrance holding member 200 can be increased. Note that the shape and structure of the surface increasing portion 225 are not particularly limited as long as the surface increasing portion 225 has a function of increasing the surface within the ventilation passage 220c. For example, the surface increasing portion 225 may be a protrusion that protrudes from the inner surface of the ventilation passage 220c toward the inside of the ventilation passage 220c. Also, the position of the surface increasing portion 225 in the ventilation passage 220c can be set as appropriate.

[0051] [3-4. Fourth Modification Example] Next, with reference to FIGS. 16 and 17, a fourth modification example capable of suppressing the oxidation of the fragrance due to the intrusion of air into the fragrance holding member 200 when the fragrance holding member 200 is not in use, such as during storage or transportation, will be described. FIG. 16 is an explanatory diagram showing an example of the configuration of the sealing member 260 according to the fourth modification example. In the fourth modification example, the inlet 222 and the outlet 224 of the ventilation passage 220 of the fragrance holding member 200 are sealed by the sealing member 260. The sealing member 260 is removed from the fragrance holding member 200 when the fragrance holding member 200 is in use. Thereby, it is possible to suppress the intrusion of external air into the fragrance holding member 200 when the fragrance holding member 200 is not in use. Therefore, the oxidation of the fragrance can be suppressed.

[0052] The sealing member 260 may be, for example, a heat-sealing film. Also, the sealing member 260 may be capable of sealing all or part of the plurality of inlets 222 or outlets 224. For example, as shown in FIG. 17, a sealing member 260a capable of sealing one inlet 222 or outlet 224 may be provided for each of the inlets 222 or outlets 224. Thereby, when the fragrance holding member 200 is in use, the user can preferentially remove the sealing member 260a corresponding to the selected fragrance from the fragrance holding member 200 and use the fragrance providing device without removing the sealing member 260a corresponding to other fragrances.

[0053] [3-5. Fifth Modification Example] Subsequently, referring to FIG. 18, a fifth modification example capable of suppressing the oxidation of the fragrance due to the irradiation of light on the fragrance when the fragrance holding member 200 is not in use, such as during storage or transportation, will be described. FIG. 18 is an explanatory diagram showing an example of the configuration of a light-shielding member 270 according to the fifth modification example. In the fifth modification example, part or all of the fragrance holding member 200 is covered by a light-shielding member 270 which is a member that blocks light. For example, as shown in FIG. 18, the light-shielding member 270 is provided so as to cover the outer peripheral surface of the fragrance holding member 200 when the fragrance holding member 200 is not in use. Thereby, when the fragrance holding member 200 is not in use, it is possible to suppress the irradiation of light such as sunlight or light emitted by a lighting fixture onto the fragrance held in the fragrance holding member 200. Therefore, the oxidation of the fragrance can be suppressed.

[0054] <4. Summary> As described above, according to the embodiments of the present disclosure, a ventilation passage 220 through which the air supplied from the air pump 300 passes is provided in a penetrating manner. The holding space 230 branches from the ventilation passage 220 and holds the fragrance. Thereby, in addition to the ventilation passage 220 through which the air flow for discharging the components vaporized from the fragrance to the outside is generated, the fragrance can also be held in the holding space 230 which is a space different from the ventilation passage 220. Therefore, the amount of the fragrance that can be held as a whole of the fragrance holding member 201 can be increased. Therefore, by providing the holding space 230 in the fragrance holding member 201, it is possible to improve the persistence of the fragrance while avoiding an increase in the size of the device.

[0055] In the above, an example has been described in which one of the plurality of ventilation passages 220 communicates with the flow path 610 of the chassis 600 that introduces the air supplied from the air pump 300 into the ventilation passage 220. However, the technical scope of the present disclosure is not limited to such an example. For example, the flow path 610 may communicate with two or more ventilation passages 220 at the same time.
