[0046] <1. Overview of Fragrance Serving Devices>

[0047] First, refer to Figures 1 to 3 The following is a brief description of the fragrance providing apparatus according to embodiments of the present disclosure. Figure 1 This is a perspective view showing the appearance of the fragrance providing device 1 according to this embodiment. Figure 2 Viewed from below Figure 1 The illustration shows a perspective view of the fragrance-providing device 1. Figure 3 yes Figure 1 Cross-sectional view of section II.

[0048] The fragrance supply device 1 according to this embodiment includes a housing 10, a fragrance emission device (fragrance emission unit) 130, and an air emission device (air emission unit) 90. The fragrance emission device 130 can selectively emit fragrances selected from a variety of fragrances.

[0049] The fragrance emission device 130 includes a housing 710, a fragrance box 200, a switching mechanism 150, and a first air supply device 840. In this embodiment, the fragrance box 200 corresponds to a fragrance holding structure. The fragrance box 200 is removable on the front side of the housing 710.

[0050] Fragrance emission device 130 supplies air from first air supply device 840 to multiple holding spaces 231 disposed in fragrance box 200. Figure 3 Each of the fragrance holders 251 (only one is shown in the diagram) evaporates and discharges the liquid fragrance contained in the fragrance holders 251 arranged in the respective holding spaces 231. For example, the fragrance discharge device 130 allows air supplied from the first air supply device 840 to pass through the holding spaces 231 of the fragrance box 200 to evaporate the liquid or wet fragrance (hereinafter collectively referred to as "liquid fragrance") and discharge the fragrance along with the air from the holding spaces 231. A switching mechanism 150 is disposed in the housing 710 and opens and closes the airflow path supplied to each holding space 231.

[0051] A first air supply device 840 is disposed within the housing 10. In addition to the first air supply device 840, a battery 810 and a circuit board 820 are disposed within the housing 10. The battery 810 is connected to the first air supply device 840 and the switching mechanism 150. The circuit board 820 includes a drive circuit for controlling the drive of the first air supply device 840 and a drive circuit for controlling the drive of the switching mechanism 150. The circuit board 820 controls the drive of the first air supply device 150 by controlling the power supply from the battery 810 to the first air supply device 840, and controls the fragrance emission from the fragrance emission device 130. Furthermore, the circuit board 820 opens and closes the airflow path supplied to each holding space 231 by controlling the power supply to the opening / closing mechanism 150.

[0052] The air emission device 90 includes a second air supply device 91 and an air supply duct 93. The second air supply device 91 is connected to the battery 810. Furthermore, the circuit board 820 includes a drive circuit for controlling the operation of the second air supply device 91. The circuit board 820 controls the operation of the second air supply device 91 by controlling the power supply from the battery 810 to the second air supply device 91, and also controls the air emission from the air emission device 90. The second air supply device 91 includes an air outlet (not shown) located on the side of the air supply duct 93, and the blower air generated by the second air supply device 91 is introduced into the air supply duct 93. The air supply duct 93 discharges the blower air generated by the second air supply device 91 in a predetermined direction.

[0053] The fragrance delivery device 1 according to this embodiment has a relatively high degree of flatness and is used as a device for discharging fragrance into a limited space. For example, the fragrance delivery device 1 is attached to a display device for experiencing virtual reality (VR) or augmented reality (AR) and provides a fragrance associated with the displayed image. Therefore, users can experience more realistic sensations.

[0054] Figure 4 and Figure 5 A head-mounted display device 1000 including a fragrance providing device 1 according to this embodiment is shown. Figure 4 This is a perspective view of the head-mounted display device 1000 as seen from the front. Figure 5 This is viewed from below. Figure 4 A perspective view of the head-mounted display device 1000 shown.

[0055] The head-mounted display device 1000 includes a mounting unit 1010, a display unit 1020, and a fragrance delivery device 1. The display unit 1020 is positioned in front of the user's eyes and displays an image. The mounting unit 1010 is connected to the display unit 1020 and mounted on the user's head, such that the display unit 1020 is positioned in front of the user's eyes.

[0056] Fragrance delivery device 1 is attached to the center of the lower part of display unit 1020. Fragrance emitted from fragrance emission device 130 is directed toward the user's nasal cavity. Additionally, air emitted from air emission device 90 is directed toward the user's nasal cavity. Fragrance delivery device 1 receives an operation signal, for example, from a control device (not shown) that controls display unit 1020 of head-mounted display device 1000, and emits fragrance or air. Specific usage examples will be described in detail later.

[0057] Note that the head-mounted display device 1000 is one example of the application of the fragrance providing device 1, and the fragrance providing device 1 can be applied to devices other than the head-mounted display device 1000.

[0058] <2. Example of Fragrance Emission Device Configuration>

[0059] Next, a configuration example of the fragrance emission device 130 will be described.

[0060] (2-1. Overall Configuration Example)

[0061] Figures 6 to 8 This is an explanatory diagram showing an example configuration of the fragrance emission device 130. Figure 6 This is a perspective view of the fragrance emission device 130. Figure 7 and Figure 8 It is a cutoff point taken in both the x and y directions. Figure 4 The cross-sectional view of the fragrance emission device 130 shown.

[0062] The fragrance emission device 130 includes a housing 710 on which the fragrance box 200 can be mounted. The housing 710 includes a mounting unit 715 on which the fragrance box 200 is mounted. A support member 760 having a cylindrical portion 761 is inserted into the mounting unit 715, and the fragrance box 200 is inserted into the cylindrical portion 761. A support shaft 763 is formed coaxially with the cylindrical portion 761 at its center, and the support shaft 763 is fitted with an axial hole 215 provided at the fragrance box 200.

[0063] A protrusion 767 is provided on the outer peripheral surface of the cylindrical portion 761 of the support member 760. The protrusion 767 serves as a positioning element when the support member 760 is inserted into the housing 710. By inserting the support member 760 into the housing 710, the protrusion 767 is aligned with the position of the slot 716 provided at the mounting unit 715 of the housing 710, so that the support member 760 is arranged in the proper position.

[0064] A protrusion 212 is provided on the outer periphery of the housing 210 of the spice box 200. The protrusion 212 serves as a positioning element when the spice box 200 is mounted on the support member 760. By inserting the spice box 200 into the support member 760, the protrusion 212 is aligned with the positioning groove 768 provided on the cylindrical portion 761 of the support member 760, so that the spice box 200 is positioned in the appropriate location.

[0065] The support member 760 has an axially penetrating air supply port 765. Air supplied from the first air supply device 840 is introduced into the holding space 231 of the spice box 200 through the air supply port 765. Multiple air supply ports 765 are configured to correspond to all the holding spaces 231 provided in the spice box 200.

[0066] The first air supply device 840 may be, for example, a diaphragm pump, which deforms the diaphragm by supplying alternating current to a piezoelectric element to draw in and pump air. The battery 810 may be a replaceable battery that only discharges, or a rechargeable secondary battery. The drive of the first air supply device 840 may be controlled, for example, by a switch on circuit board 820.

[0067] Note that there are no particular limitations on the first air supply device 840, as long as it can be driven by power supplied from the battery 810. In addition to a diaphragm pump, for example, an air supply device that rotates a fan can also be used.

[0068] (2-2. Spice Box (Spice Preservation Structure))

[0069] Next, an example of a spice box 200 that can be detached from the housing 710 will be described in detail. In this embodiment, a spice box having five holding spaces will be described as an example, wherein each of the five holding spaces is provided with a spice holder 251.

[0070] Figures 9 to 12 This is a diagram illustrating a configuration example of the spice box 200. Figure 9 This is an exploded perspective view of the spice box 200. Figure 10 This is a front view of the fragrance box 200 as seen from the axial front side (fragrance spray side). Figure 11 This is a rear view of the spice box 200 as seen from the rear side (air inflow side) in the axial direction. Figure 12 It is an axial cross-sectional view of the spice box 200, and it is Figure 10 and Figure 11 The arrow diagram for section II-II is shown.

[0071] The spice box 200 has a generally cylindrical shape. The spice box 200 has multiple (five in this embodiment) holding spaces 231a to 231e (hereinafter collectively referred to as holding spaces 231 unless otherwise specified) that allow air supplied from the first air supply device 840 to pass through. Each holding space 231 contains a spice holder 251 that holds liquid spice. The spice may be, for example, essential oil, essential oil diluted with ethanol, or the like. The number of holding spaces 231 may be four or fewer, or six or more.

[0072] The fragrance box 200 according to this embodiment includes a housing 210 and a fragrance holder 251. The housing 210 includes a first housing body 211 and a second housing body 100 fixed to the front side of the first housing body 211. The fragrance holder 251 contains liquid fragrance and is arranged in each of a plurality of holding spaces 231 provided in the housing 210. Air introduced into the holding spaces 231 is allowed to pass through even when the fragrance holder 251 is arranged in the holding space 231.

[0073] For example, each fragrance holder 251 can be a holder obtained by impregnating a substrate with a liquid fragrance. In this case, porous or fibrous materials including polyester, nylon, felt, polyacetal, etc., can be used as the impregnating material. Furthermore, the impregnating material is preferably a material resistant to liquid fragrance. The liquid fragrance can be, for example, essential oil, essential oil diluted with ethanol, or the like. For each holding space 231, the liquid fragrance to be contained in the fragrance holder 251 can be different or the same.

[0074] The spice box 200 has protrusions 212a and 212b on its outer peripheral surface, which serve as positioning elements when the spice box 200 is installed. Protrusion 212a is provided on the second housing body 100, and protrusion 212b is provided on the first housing body 211, and the protrusions are formed to be connected to each other along the axial direction.

[0075] The first housing body 211 has a cylindrical shape, with its axial length greater than its diameter. An axial hole 215 with openings at both ends along the axial direction is provided in the central portion of the first housing body 211. Within the first housing body 211, five retaining spaces 231 are arranged at equal intervals of 60 degrees around an axis, while one space is designated as a pseudo-space 232. The retaining spaces 231 and the pseudo-space 232 are open on the front side of the first housing body 211. Furthermore, the rear sides of the retaining spaces 231 open outwards through air inlet holes 221, while the rear side of the pseudo-space 232 is closed.

[0076] The first housing body 211 has the same number of air inlet holes 221a to 221e (hereinafter collectively referred to as air inlet holes 221 unless otherwise specified) as the number of retaining spaces 231 on the rear end surface. The air inlet holes 221 open each retaining space 231 outwards. In this embodiment, five air inlet holes 221a to 221e, together with a dummy hole 223, are arranged at equal intervals of 60 degrees around an axis. The air inlet holes 221 can communicate with an air supply port 765 of a support member 760 inserted into and fixed to the housing 710. The air supply port 765 and the air inlet holes 221 serve as air supply paths to supply air to each retaining space 231. Note that the multiple retaining spaces 231 and air inlet holes 221 need not be arranged at equal intervals.

[0077] The second housing body 100 has a cylindrical shape, and its axial length is less than its diameter. The second housing body 100 is joined to and fixed to the front end of the first housing body 211. The outer peripheral surface of the second housing body 100 is knurled and has a plurality of fine grooves formed along the circumferential direction.

[0078] An axial hole 111 with openings at both ends along the axial direction is provided in the central portion of the second housing body 100. When the second housing body 100 is attached to the first housing body 211, the axial hole 111 of the second housing body 100 is integrated with the axial hole 215 of the first housing body 211, thereby forming a single axial hole. Around the axial hole 111, a plurality of fragrance emission holes 101a to 101e (hereinafter collectively referred to as fragrance emission holes 101 unless otherwise specified) with openings at both ends along the axial direction are provided. The plurality of fragrance emission holes 101, together with a dummy hole 103, are arranged around the axial hole 111 at equal intervals (equal intervals of 60 degrees in this embodiment). However, the fragrance emission holes 101 need not be arranged at equal intervals.

[0079] With the second housing body 100 attached to the first housing body 211, the plurality of fragrance emission holes 101a to 101e communicate with the holding spaces 231a to 231e respectively and open the holding spaces 231a to 231e outward. The air inlet holes 221a to 221e provided at each of the holding spaces 231a to 231e and the fragrance emission holes 101a to 101e of the second housing body 100 are located in the same phase around the axis. That is, the air inlet holes 221 and the fragrance emission holes 101 provided at each of the holding spaces 231 are linearly connected to each other in the axial direction.

[0080] On the outer peripheral surface of the second housing body 100, at a position corresponding to the outer peripheral portion where the dummy hole 103 is arranged, a protrusion 212a having a predetermined length in the axial direction is provided. When the second housing body 100 is attached to the first housing body 211, the protrusion 212a of the second housing body 100 is arranged to be continuous with the protrusion 212b of the first housing body 211, so that the protrusion 212 forms a unit.

[0081] Air introduced into the holding space 231 is allowed to pass through the fragrance box 200 according to this embodiment, even with the fragrance holder 251 arranged therein. When air passes through the holding space 231, the liquid fragrance is evaporated, mixed with the air, and discharged. Furthermore, since the space from the air inlet hole 221, which serves as the air supply port, to the fragrance discharge hole 101, which serves as the discharge port, is a sealed space without any other openings, all fragrance that evaporates through ventilation can be effectively discharged from the discharge port.

[0082] If the spice box 200 can be detached from the spice dispensing device 130, only the spice box 200 can be easily replaced, and the fragrance dispensing device 1 can be used for a long time. In addition, since different spice boxes 200 can be easily replaced according to purpose, feeling, etc., different kinds of spices can be easily used even when the number of spices contained in a spice box 200 is not large.

[0083] (2-3. Switching mechanism)

[0084] return Figures 6 to 8 The switching mechanism 150, which switches whether air passage is allowed for each holding space 231, will be described in detail.

[0085] In the fragrance emission device 130 of the fragrance supply device 1 according to this embodiment, the switching mechanism 150 includes an air supply port 765 and an air inlet 221, and opens and closes the air supply path through which air flows to the holding space 231. The switching mechanism 150 includes a component that deforms under physical or chemical stimulation, and switches whether air passage is allowed for each holding space 231.

[0086] The switching mechanism 150 includes a valve component 151, an actuating component 153, and a deforming component 155. The valve component 151, the actuating component 153, and the deforming component 155 are independently provided for communicating with each air supply port 765 in each retaining space 231 of the spice box 200. Figure 14 Only the valve component 151c, the actuating component 153c, and the deformable component 155c corresponding to the retaining space 231c are shown.

[0087] A channel chamber 713 is formed inside the housing 710. The substrate 160 is attached to the rear end face of the housing 710 to cover the channel chamber 713. For example, the airtightness of the contact between the housing 710 and the substrate 160 is improved by performing a process such as welding.

[0088] The passage chamber 713 is connected to an air inlet 711 from the first air supply device 840 and an air supply port 765 communicating with each retaining space 231. At the center of the passage chamber 713, a rear shaft portion 769 extending rearward from the cylindrical portion 761 of the support member 760 is arranged. Corresponding to each retaining space 231a to 231e, valve components 151a to 151e, actuating components 153a to 153e, and deformable components 155a to 155e are arranged around the rear shaft portion 769. Hereinafter, unless otherwise specified, they will be collectively referred to as valve component 151, actuating component 153, or deformable component 155.

[0089] Air introduced into the channel chamber 713 from the inlet 711 passes through the gap between the switching mechanism 150 and the rear shaft portion 769 and diffuses throughout the channel chamber 713. Within the channel chamber 713, the gap between the switching mechanism 150 and the rear shaft portion 769 is kept relatively small, so that when the first air supply device 840 is activated, air is rapidly supplied to the holding space 231.

[0090] Valve components 151a to 151e are supported by support shafts 157a to 157e respectively disposed in the channel chamber 713, allowing them to slide in the axial direction. Specifically, each valve component 151 is provided with an insertion hole 151ca opening at the rear, and the tip portion of the support shaft 157 is inserted into the insertion hole 151ca, thereby supporting the valve component 151 and allowing it to slide in the axial direction. The tip surface of each valve component 151 can contact the edge surface of the air supply port 765 surrounding the support component 760. The support shaft 157 and the insertion hole 151ca are machined into a D-shaped cross-section, so that the valve component 151 cannot rotate.

[0091] Each actuating element 153 is arranged between the valve component 151 and the rear end portion of the support shaft 157, and actuates the valve component 151 in a forward direction, i.e., in the direction of closing the air supply port 765. In this embodiment, a helical spring is used as each actuating element 153, the tip of which is embedded in the valve component 151c, and its rear end portion is supported by the rear end portion of the support shaft 157c.

[0092] Each deformable component 155 deforms by physical or chemical stimulation, causing the valve component 151 to move in the retraction direction (i.e., the direction of opening the air supply port 765) against the pushing force of the actuating component 153. In this embodiment, a fine-wire shape memory alloy is used as one aspect of a temperature-sensitive deformable component, serving as each deformable component 155. The shape memory alloy generates heat and deforms due to resistance during energization.

[0093] Figure 13 This is a schematic diagram showing the valve component 151 and the deformable component 155. The deformable component 155, comprising a fine-wire shape memory alloy, is mounted such that it extends from one of the two cantilevered portions 152a and 152b, which are provided on the two side surfaces of the valve component 151 and have a central shaft inserted between them, through the valve component 151 to the other cantilevered portion 152b. That is, the deformable component 155, mounted with its two ends extending rearward, is locked to the valve component 151. Although not shown, the two ends of the deformable component 155 are electrically connected to the drive circuit of the circuit board 820.

[0094] like Figure 7 As shown, both ends of the deformable member 155 extend from the channel chamber 713 through the inner holes of orifices 161a and 161b, respectively. These orifices 161a and 161b are crimped while the deformable member 155 penetrates the inner holes. Therefore, the deformable member 155 is fixed, and the airtightness of the channel chamber 713 to the outside is improved. Orifices 161a and 161b can be further subjected to processes such as welding to improve airtightness. In this case, after pre-stretching the deformable member 155, orifices 161a and 161b are crimped. Therefore, the valve member 151 is in a state where the air supply port 765 is closed and tension is generated in the deformable member 155 when it is not energized, and responsiveness is improved until the deformable member 155 begins to move when energized.

[0095] Figure 14 and Figure 15 This is an explanatory diagram showing the operation of the switching mechanism 150. Figure 14 This is a cross-sectional view showing the condition of the deformable part 155c in a non-energized state. Figure 15 This is a cross-sectional view showing the condition of the deformable component 155c in the energized state.

[0096] In the non-energized state of the deformable member 155c, the valve member 151c is pushed forward by the pushing force of the pushing member 153, and the air supply port 765 of the support member 760 is closed. On the other hand, in the energized state of the deformable member 155c, the valve member 151c retracts due to the contraction of the deformable member 155, resisting the pushing force of the pushing member 153, and the air supply port 765 of the support member 760 is opened. Therefore, air introduced into the channel chamber 713 from the first air supply device 840 is supplied to the holding space 231 via the air supply port 765 and the air inlet hole 221. The air supplied to the holding space 231, together with the fragrance evaporating in the holding space 231, is discharged from the fragrance emission hole 101.

[0097] Valve component 151, actuating component 153, and deformable component 155 are disposed corresponding to each retaining space 231, and the energization of each deformable component 155a to 155e is controlled by the drive circuit of circuit board 820. Therefore, when an operation signal is input to the drive circuit of circuit board 820 while driving the air supply device 840, air is supplied to the desired retaining space 231, and different fragrances can be emitted at any time sequence.

[0098] At this time, the retraction amount of the valve component 151 can be adjusted according to the electrical current supplied to the deformable component 155. Therefore, even if the amount of air supplied from the first air supply device 840 is constant, the airflow through the holding space 231 can be adjusted. Furthermore, by supplying air to multiple holding spaces 231 while adjusting the retraction amount of the valve component 151, various fragrances can be emitted from the fragrance emission device 130 while adjusting the mixing ratio of different fragrances.

[0099] The configuration of the switching mechanism 150 is not limited to the examples described above. Various modifications can be made as long as it includes a deformable component that deforms under physical or chemical stimulation and can open and close the air supply path to each holding space 231 as the deformable component deforms. Here, deformation caused by physical or chemical stimulation refers to a change in the shape of the component due to electrical current, electromagnetic action, thermal reaction, humidity change, light reaction, chemical reaction, etc. Besides shape memory alloys, bimetallic materials, stretchable materials, etc., can also be used as such deformable components.

[0100] Furthermore, the valve component 151 of the switching mechanism 150 is not limited to a valve component that moves in the front-to-back direction, but can also slide in a direction intersecting the axial direction of the air supply path. Additionally, the switching mechanism may have a throttle function that reduces the area of ​​the air passage by deforming a deformable component, or a door function that opens and closes the air passage by rotating a rotating plate. Furthermore, the switching mechanism may have a component with a hole forming a portion of the passage provided in the center of the air passage, thereby allowing the air passage to be connected by moving this component.

[0101] <3. Configuration Examples of Air Emission Devices>

[0102] When using a fragrance emission device capable of emitting multiple types of fragrances at short intervals, these fragrances are mixed, and the user may have difficulty perceiving the fragrance they intended to smell. Therefore, the fragrance supply device 1 according to this embodiment includes an air emission device 90.

[0103] As described above, the air emission device 90 includes a second air supply device 91 and an air supply duct 93. Air generated by the second air supply device 91, powered by the battery 810, is discharged in a predetermined direction via the air supply duct 93. The air emission direction of the air emission device 90 is designed to intersect with the fragrance emission direction of the fragrance emission device 130. Therefore, near the location where the air emitted by the air emission device 90 intersects with the fragrance emitted by the fragrance emission device 130, residual fragrance can be dispersed by air.

[0104] Figure 16 It is shown Figure 4 and Figure 5 This diagram illustrates the emission direction L1 of the fragrance emission device 130 and the emission direction L2 of the air emission device 90 in the head-mounted display device 1000 shown. (The last sentence appears to be incomplete and possibly refers to a separate topic.) Figure 4 and Figure 5 When the head-mounted display device 1000 is worn on the user's head H, the emission direction L1 of the fragrance emission device 130 and the emission direction L2 of the air emission device 90 are designed to intersect near the nasal cavity of the user's nose N. Therefore, when the fragrance emission device 130 emits different fragrances in sequence, the user can smell the next fragrance while dispelling the remaining fragrance.

[0105] <4. Circuit Configuration Example>

[0106] Next, an example of the circuit configuration for driving and controlling the fragrance emission device 130 and the air emission device 90 of the fragrance delivery device 1 will be described.

[0107] Figure 17This is a simplified illustration of an example of a control circuit 20 that controls the power supply from battery 810 to deformable components 155a to 155e, the first air supply device 840, and the second air supply device 91. The control circuit 20 is controlled by a control unit (not shown). The control unit may be, for example, a processor, such as a central processing unit (CPU) or a microprocessor unit (MPU).

[0108] The control circuit 20 includes a main switch 21, which switches the power supply to the entire device on / off. Additionally, the control circuit 20 includes switches 23a to 23e, which switch the power supply to the respective deformable components 155a to 155e; switch 25, which switches the power supply to the first air supply device 840; and switch 27, which switches the power supply to the second air supply device 91. Power is supplied to the deformable components 155a to 155e, the first air supply device 840, and the second air supply device 91 when the main switch 21 is on.

[0109] Switches 23a to 23e, 25, and 27 can be linear switches capable of linearly setting the magnitude of the power supply current. If switches 23a to 23e are linear switches, the amount of movement of valve component 151 can be linearly changed, i.e., the channel area of ​​the air supply path, and the fragrance emission flow rate can be adjusted. Furthermore, if switches 25 and 27 are linear switches, the blower volume of the first air supply device 840 or the second air supply device 91 can be linearly changed, and the flow rate of the emitted fragrance or air can be adjusted.

[0110] The on / off actions of switches 23a to 23e, 25 and 27 of control circuit 20 can be performed according to the user's button operation or according to the operation signal from the control device.

[0111] Furthermore, the control circuit 20 may include a wireless communication interface. Therefore, the fragrance providing device 1 can be controlled by receiving operating signals from an external control device.

[0112] <5. Action Examples>

[0113] Next, an example of the operation of the fragrance providing device 1 according to this embodiment will be described.

[0114] The control circuit 20 controls the emission of fragrance from the fragrance emission device 130 based on the user's button operation or the operation signal from the control device. For example, the user can select and emit a desired fragrance according to his / her feelings, or the control circuit 20 can be driven to cause the control device to emit an appropriate fragrance based on the content or atmosphere of the image or moving image viewed by the user.

[0115] (5-1. Examples of actions performed through user interaction)

[0116] Figure 18 An example of a screen display 30 for operating a device is shown, used by a user to control the emission of fragrance and air. Such an operating device can be a smartphone or tablet terminal. It can also be a dedicated operating device. The illustrated screen display 30 includes an operating unit 31 for selecting the on / off state of the main switch 21, an operating unit 33 for selecting the fragrance emitted from the fragrance emission device 130, and an operating unit 35 for selecting the flow rate of air emitted from the air emission device 90. The user can control the emission of fragrance and air by pressing desired operating buttons according to the screen display 30.

[0117] The user presses the appropriate operating button according to the type of fragrance to be emitted, based on the holding space 231 (shown as SLOT1 to SLOT5 in the figure). In the example shown, the control unit opens the valve component 151 leading to the holding space 231 corresponding to the button selected by the user, so as to supply air to the holding space 231 and emit the fragrance within a predetermined time (e.g., one second).

[0118] Not only can the fragrance be selected, but the duration of fragrance release can also be chosen. For example, the user can select the fragrance release time at three levels (0.3 seconds, one second, and three seconds), causing the valve component 151 to remain open according to the selected time. Furthermore, the fragrance intensity can be selected. For example, the user can select the fragrance intensity at three levels (high, medium, and low), thereby adjusting the opening degree of the valve component 151 according to the selected intensity.

[0119] In addition, Figure 18 In the example shown, the user can select the airflow rate at three levels (HI / MID / LO). The control unit can cause the air emission device 90 to continuously emit air according to the selected flow rate. By continuously emitting air, residual fragrance can be quickly dissipated after the user has smelled the emitted fragrance, while the area around the user's nose remains odorless outside the period of fragrance emission. Therefore, mixing with subsequent fragrances can be suppressed. In this case, the control unit can stop air emission only during the fragrance emission period.

[0120] Furthermore, the control unit can discharge air from the air discharge device 90 after discharging fragrance from the fragrance discharge device 130. By discharging air after discharging fragrance, residual fragrance can be dissipated after the user has smelled the emitted fragrance. In this case, the control unit can discharge air for a predetermined time or discharge a predetermined amount of air, or adjust the amount of air discharged according to the amount of fragrance emitted. In addition, power consumption can be reduced according to the frequency of fragrance emission.

[0121] Furthermore, the control unit can discharge air from the air discharge device 90 immediately before discharging fragrance from the fragrance discharge device 130. That is, the control unit can discharge fragrance from the fragrance discharge device 130 after discharging air from the air discharge device 90. By discharging air immediately before discharging fragrance, the user can become aware of the fragrance discharge.

[0122] (5-2. Examples of actions performed via control device commands)

[0123] The fragrance emission and air emission performed by the fragrance supply device 1 can be controlled based on operating instructions from another control device, such as a control device that controls the display of still or moving images. For example, the fragrance supply device 1 can be controlled to create an atmosphere based on the content of the moving image to be reproduced in AR, VR, movies, etc. Alternatively, in tourist attractions or similar facilities, the fragrance supply device 1 can be controlled to create an atmosphere based on the user's movement.

[0124] Figure 19 An example of operation of the aroma-providing device 1, including an aroma emission device 130 and an air emission device 90, is shown. This example of operation involves providing the user with an aroma reminiscent of the displayed food while simultaneously displaying an image of the food. Specifically, the aroma emission device 130 provides aroma A for a short period through a holding space 231 (SLOT1), and then aroma B through another holding space 231 (SLOT5). In this case, the image display control device is configured to output an operation command to the control unit of the aroma-providing device 1 to generate an appropriate aroma based on the duration of the image display.

[0125] exist Figure 19 In the example shown, after adjusting at least one of the output of the first air supply device 840 or the opening of the valve component 151, the intensity of fragrance A emitted from the fragrance supply device 1 is gradually increased. The second air supply device 91 is activated to discharge air from the air discharge device 90 (E1 in the figure), and the intensity of fragrance A is reduced. Furthermore, air is discharged from the air discharge device 90 again (E2 in the figure), and fragrance A is immediately dispersed before fragrance B is emitted. Then, at least one of the output of the first air supply device 840 or the opening of the valve component 151 is adjusted so that the intensity of the emitted fragrance B gradually increases. Then, air is emitted after fragrance B is emitted (E3 in the figure), and the intensity of fragrance B is reduced.

[0126] In this way, the fragrance providing device 1 provides fragrance based on operating instructions from another control device to create an atmosphere for the user. Therefore, when different fragrances are provided to the user in a short period of time, the fragrances are less likely to mix, and the atmosphere provided to the user can be appropriately controlled.

[0127] Note that even when the fragrance supply device 1 is activated by an operation command from the control device, the operation of the control unit described above (5-1.) can also be applied to the air emission method corresponding to the fragrance emission. Furthermore, instead of the configuration example in which information about the operating modes of the fragrance emission device 130 and the air emission device 90 is stored in another control device and an operation command is output from that other control device to the fragrance supply device 1, information related to the operating modes linked to dynamic images, etc., can be pre-stored in the control unit of the fragrance supply device 1, and the fragrance supply device 1 itself can operate the fragrance emission device 130 and the air emission device 90 according to the operating modes.

[0128] <6. Variations>

[0129] In addition to the examples above, the fragrance emission device 130 can be modified in various ways.

[0130] For example, although the fragrance emission device 130 and the air emission device 90 are configured as a single unit in the example of the above embodiment, the fragrance emission device 130 and the air emission device 90 can be configured separately.

[0131] Figure 20 and Figure 21 A head-mounted display device 1001 with a fragrance delivery device according to a modified example is shown. Figure 20 This is a perspective view of the head-mounted display device 1001 as seen from the front. Figure 21 It is viewed from below. Figure 20 A perspective view of a portion of the head-mounted display device 1001 shown.

[0132] According to this modified example, the head-mounted display device 1001 includes a mounting unit 1010, a display unit 1020, a fragrance emission device 130, and an air emission device 90, with the fragrance emission device 130 and the air emission device 90 arranged separately. The fragrance emission device 130 is arranged above the display unit 1020 so as to be in front of the user, and the air emission device 90 is arranged below the display unit 1020. The fragrance emission device 130 and the air emission device 90 are connected to each other via an air supply pipe 80, and the fragrance emitted from the fragrance emission device 130 is sent to the air emission device 90 via the air supply pipe 80.

[0133] The air emission device 90 includes an air supply duct 97 and a second air supply device 91. The air supply duct 97 has a guide portion 98 on which the user's nose is placed. The air supply duct 97 is open at the end where the guide portion 98 is provided. An air supply pipe 80 is connected to the end opposite to the end where the guide portion 98 is provided. The fragrance delivered from the fragrance emission device 130 via the air supply pipe 80 passes through the guide portion 98 and is guided to the user's nose.

[0134] The second air supply device 91 is capable of discharging air or fragrance from the air supply duct 97 to the outside. That is, Figure 20 and Figure 21 The air exhaust device 90 of the head-mounted display device 1001 shown is able to exhaust air from inside the air supply duct 97, rather than exhausting air toward the user's nasal cavity. Therefore, after the fragrance is emitted toward the guide portion 98 where the user's nose is located, the residual fragrance can be quickly expelled from inside the air supply duct 97.

[0135] The airflow discharged from the second air supply device 91 can be directed to the user's mouth. Figure 22 This is an illustrative diagram showing how the airflow discharged from the second air supply device 91 is guided to the user's mouth. For example, because the airflow is guided to the user's mouth, if the second air supply device 91 operates for a short period of time before releasing the fragrance, the airflow collides with the vicinity of the mouth and enables the user to be aware of the fragrance release.

[0136] Note that, according to Figures 20 to 22 In the modified example shown, the fragrance emission device 130 can be arranged in a position other than above the display unit 1020 in the head-mounted display device 1001.

[0137] Furthermore, the fragrance emission device 130 may include a fragrance mixing chamber into which air that has passed through the various holding spaces 231 of the fragrance box 200 may flow. By providing a fragrance mixing chamber, air can pass through multiple holding spaces 231 containing different types of fragrances simultaneously, and can be emitted after these fragrances have been mixed. Thus, in the case of a fragrance box capable of holding five types of fragrances, for example, a total of 30 types of fragrances can be emitted through combinations of only one or more types.

[0138] Furthermore, when a fragrance mixing chamber is provided, a configuration for generating a stirring flow can be installed inside the fragrance mixing chamber. For example, fins can be installed vertically from the inner wall surface of the fragrance mixing chamber, or a static mixer capable of generating a stirring flow can be installed inside the fragrance mixing chamber.

[0139] Furthermore, although the switching mechanism 150 of the aforementioned fragrance emission device 130 opens and closes the air supply path to the holding space 231, this switching mechanism can also open and close the fragrance emission path from the holding space 231. Since air cannot pass through the holding space 231 even when the fragrance emission path is closed, the switching mechanism can switch whether fragrance can be emitted. When the switching mechanism is configured to open and close the fragrance emission path, leakage of fragrance from the holding space 231 other than the holding space 231 that allows air to pass through can be prevented. On the other hand, when the switching mechanism is configured to open and close the air supply path, damage to the components constituting the switching mechanism by corrosion from liquid fragrances or the like can be prevented.

[0140] Furthermore, the switching mechanism 150 can be installed on both the air supply path and the fragrance emission path. Therefore, the effect of preventing fragrance leakage from the retaining space 231, which does not allow air to pass through, can be enhanced.

[0141] Furthermore, the fragrance supply device 1 may include multiple fragrance boxes and multiple on / off mechanisms. In this case, the multiple fragrance boxes may be arranged in series so that air supplied from the first air supply device 840 passes sequentially through the multiple fragrance boxes. By passing air through the multiple fragrance boxes, different fragrances can be mixed, or the intensity of the same fragrance can be increased.

[0142] Furthermore, the fragrance supply device 1 may include multiple fragrance emission devices 130. Therefore, more types of fragrances can be emitted. In this case, each of the multiple fragrance emission devices 130 may include a first air supply device 840, or some or all of the multiple fragrance emission devices 130 may include a common first air supply device 840. Therefore, various fragrances can be emitted. Furthermore, the multiple fragrance emission devices 130 can be arranged such that the fragrance emission ports from the multiple fragrance emission devices 130 face each other. Therefore, fragrances can be easily mixed and emitted.

[0143] Furthermore, at least one of the multiple holding spaces 231 of the fragrance box 200 can be used without containing fragrance. For example, the intensity of the fragrance can be reduced by passing air through one of the holding spaces 231 containing fragrance while simultaneously passing air through the holding space 231 without fragrance. Moreover, by providing a holding space 231 without fragrance, odorless air can be vented, and the air exhaust device 90 can be omitted. Furthermore, a deodorizing agent such as activated charcoal can be placed instead of fragrance. Therefore, the deodorizing effect of residual fragrance can be enhanced.

[0144] Furthermore, in the fragrance supply device 1 according to the above embodiment, at least one of the fragrance emission direction or the air emission direction can be adjusted. Therefore, the fragrance or air emission direction can be adjusted according to the user's preference.

[0145] As described above, the fragrance supply device 1 according to this embodiment allows for easy replacement or replenishment of fragrances simply by replacing the fragrance box 200, because the fragrance supply device includes a fragrance dispensing device 130 using a removable fragrance box 200, which has multiple holding spaces 231 each containing a fragrance. Therefore, the fragrance supply device 1 can be used for a long time.

[0146] Furthermore, since the fragrance supply device 1 according to this embodiment includes a switching mechanism 150 for switching whether air passage is permitted for each of the plurality of holding spaces 231, the emitted fragrance can be switched quickly. Furthermore, since the fragrance supply device 1 includes a switching mechanism 150 for switching whether air passage is permitted for each of the plurality of holding spaces 231, air can be allowed to pass through the plurality of holding spaces 231 simultaneously, and the fragrance can be emitted while mixing the fragrances. Furthermore, since the switching mechanism 150 includes a deformable member 155 that deforms upon physical or chemical stimulation, vibration during operation can be reduced.

[0147] Furthermore, the fragrance supply device 1 according to this embodiment includes an air emission device 90, and can replace the air around the nose by emitting air toward the user's nose or blowing air away from the user's nose. Therefore, the fragrance can be eliminated or prepared for switching fragrances. Moreover, instead of adjusting the amount of fragrance emitted from the fragrance emission device 130, or adjusting the fragrance intensity in conjunction with adjusting the amount of emitted fragrance, the fragrance intensity can be adjusted by adjusting the amount of air emitted from the air emission device 90.
