Description

Technical Field

[0001] This technology relates to an odor component retention component, an odor supply device, and an odor supply unit; more specifically, it relates to an odor component retention component and an odor supply device that supply odor by opening and closing an air supply path and an odor release path. Background Technology

[0002] Previously, a technique was proposed that supplies air to a containment device that houses an odor-containing component and releases the odor-containing component through the flow of air, thereby providing an odor to the user.

[0003] For example, Patent Document 1 discloses an odor delivery device, characterized by comprising: a shielding cylinder, which is cylindrical in shape, with an internal cavity serving as an odor component delivery channel and a partial opening on its side; an odor component container, which contains odor components and is disposed on the outer surface of the shielding cylinder, and has an opening on its side; and an air supply unit capable of supplying air to one end of the odor component delivery channel. Through a relative rotational action between the shielding cylinder and the odor component container while they are in close contact, the opening of the shielding cylinder overlaps with the opening of the odor component container, thereby enabling a through-flow between the interior of the odor component container and the odor component delivery channel. Alternatively, through a relative rotational action between the shielding cylinder and the odor component container while they are in close contact, the opening of one of the shielding cylinder and the odor component container overlaps with the portion other than the opening of the other, thereby enabling a non-through-flow between the interior of the odor component container and the odor component delivery channel.

[0004] According to the odor-providing device described in Patent Document 1, it is said to be able to suppress the release of undesirable odor components and to provide odor at appropriate timing.

[0007] Patent Document 1: Japanese Patent Application Publication No. 2013-094436 Summary of the Invention

[0008] The technical problem that the invention aims to solve

[0009] However, in the odor-providing device of Patent Document 1, it is conceivable that the odor component may leak from openings such as the fitting part between the container holding the odor component and the outer shell, or the odor inlet / outlet communicating with the outside. This raises concerns about problems such as odor component deterioration (weakening due to volatilization and deterioration due to oxidation), mixing, melting, and labels adhering to the outer shell.

[0025] Alternatively, the inner wall surface can be made of metal.

[0026] Alternatively, the odor component retaining component may be a box assembled into the odor providing device.

[0027] In addition, this technology provides an odor providing device comprising an odor component holding member and a drive mechanism.

[0066] (1-1) Overall Composition

[0067] Reference Figures 1 to 3 Hereinafter, an example of the configuration of the odor providing device 100 according to the first embodiment of the present technology will be described. Figure 1 This is a perspective view showing an example of the configuration of the odor providing device 100 according to this embodiment. Figure 2This is a side cross-sectional view showing an example of the configuration of the box (odor component retention member) 101 included in the odor supply device 100. Figure 3 This is a side sectional view showing an example of the configuration of the odor providing device 100.

[0068] like Figure 1 As shown, the odor supply device 100 according to this embodiment includes: a cylindrical box 101 that serves as an odor component holding member; a cylindrical drive mechanism 102; and an ejection hole 103 formed at the front end of the box 101, which releases odor-containing air containing odor components to the outside.

[0069] The box 101 includes: a connecting portion 110 detachably connected to a drive mechanism portion 102, the drive mechanism portion 102 being connected to a movable portion movable in a manner capable of opening and closing an opening, and driving the movable portion; a first housing 111 connected to the connecting portion 110; a second housing 112 connected to the first housing 111; and a housing front end portion 113 connected to the second housing 112. The first housing 111, the second housing 112, and the housing front end portion 113 are configured in a stacked structure and connected together. The drive mechanism portion 102 includes a drive mechanism receiving portion 114 for housing the drive mechanism.

[0070] like Figure 2 As shown, the odor supply device 100 is a device that allows air to flow through an internal space selected from the internal spaces R1 and R2 provided within the housing 101 to hold a desired odor component, and vaporizes the odor component held by the odor component holder 130 disposed in the internal space to release it. For example, in the odor supply device 100, the odor component holder 130 is disposed in the internal space R1 of the first housing 111 of the housing 101, and air supplied by an air pump (not shown) is allowed to flow, thereby vaporizing the liquid odor component or the odor component in a humid state (hereinafter referred to as the liquid odor component) and releasing the odor from the internal space R1 through the internal space R2 and the nozzle 103 to the outside along with the air.

[0071] It should be noted that, in this technology, "odor" can include all odors that stimulate some or all of the olfactory receptors present in the nasal cavity, such as pleasant and unpleasant odors. In addition to olfactory receptors, the nasal cavity also contains receptors for the trigeminal nerve, etc. Therefore, the odor in this technology is a broad concept that includes all odors that stimulate some or all of these receptors.

[0072] The odor-providing device 100 is used, for example, as a device to release odors into a limited space, specifically for olfactory testing, olfactory training (olfactory stimulation therapy), etc. It should be noted that olfactory training here is interpreted broadly and may also include practice for olfactory identification exams, sommelier exams, aromatherapy certifications, etc. Furthermore, it can also be used for flavor simulation in the development of beverages and food. Additionally, it can be integrated into relaxation products such as automobiles, head-mounted displays, neck pillows, and eye pillows. When integrated into an automobile, for example, it can generate an odor based on instructions from the driver or passengers, or it can detect the vehicle's location information, the driver's or passengers' activities or biosignals, and generate an odor based on the detection results. When integrated into a head-mounted display, for example, it can generate an odor in conjunction with an image displayed on the display, or it can detect the user's activities or biosignals, and generate an odor based on the detection results. When integrated into relaxation products such as neck pillows and eye pillows, for example, it can generate an odor based on user instructions, or it can detect the user's activities or biosignals, and generate an odor based on the detection results. In cases where the scent is released into a limited space, such as when a user releases the scent from the scent-providing device 100 once or multiple times near their face to relax, the scent-providing device 100 releases the fragrance with high linear propagation, making it difficult for the scent to spread over a wide area, thus making it difficult for people around to detect the scent.

[0073] In addition, the odor-generating device 100 can also be used as a device to release odors into a large space. Specifically, it can be mounted on vending machines, digital signage, robots, and other products that attract customers. When mounted on a product that attracts customers, for example, it can detect the actions and expressions of a large number of unspecified users and generate odors for specific users or multiple users based on the detection results.

[0074] Furthermore, the odor-providing device 100 can be portable, which can be carried by the user, or it can be stationary.

[0075] (1-2) Box (Odor component retention component)

[0076] Next, an example of the configuration of the box 101, which is the odor component retention member of the odor supply device 100 according to this embodiment, will be described.

[0077] As described above, the box 101 includes: a connecting portion 110 detachably connected to the drive mechanism portion 102; a first housing 111 connected to the connecting portion 110; a second housing 112 connected to the first housing 111; and a housing front end portion 113 connected to the second housing 112. The first housing 111, the second housing 112, and the housing front end portion 113 are configured in a stacked structure and connected together. The box 101 is cylindrical, but the shape of the odor component retaining component involved in this technology is not limited to a cylindrical shape; for example, it can be a cylinder, a cuboid, a cube, or other suitable shape.

[0078] like Figure 2 As shown, the connecting portion 110 is screwed into the first housing 111 via a threaded cutting portion 121 and is sealed by an O-ring 122 disposed in the fitting portion with the first housing 111. The connecting portion 110 has a first shaft 123 inside, serving as an actuating shaft. Similarly, the first housing 111 is screwed into the second housing 112, and the second housing 112 is screwed into the front end portion 113 of the housing via threaded cutting portions 121, and is sealed by an O-ring 122 disposed in the fitting portion. The box 101 seals each fitting portion using the threaded cutting portion 121 and the O-ring 122, preventing odor components from leaking from these fitting portions. It should be noted that the O-ring 122 is not limited to this; any airtight sealing structure capable of sealing each fitting portion is acceptable, including protruding embedded structures. Additionally, the fitting portion may contain an oil-sealing material and / or an elastic material.

[0079] The first housing 111 has: an internal space R1; a first opening 124 and a second opening 125 that open the internal space R1 to the outside and release odor-containing air, a mixture of odor components and air, toward the ejector hole 103; and a second shaft 126 as an actuating shaft and a first spring 128 as an elastic body, the second shaft 126 and the first spring 128 being movable parts capable of opening and closing at least one of the first opening 124 and the second opening 125. To achieve a tight seal and prevent leakage of odor components to the outside, the first housing 111 is formed of a material with low gas permeability, such as a polymer resin, metal, inorganic crystal, or glass.

[0080] In housing 101, the first opening 124, the second opening 125, the second shaft 126, the first spring 128, and the odor component retainer 130 are arranged substantially parallel to the direction in which the first housing 111, the second housing 112, and the front end portion 113 of the housing are stacked. The odor component retainer 130 may also be arranged in multiple internal spaces. It should be noted that the first spring 128 may also be subjected to force in the sealing direction of the first opening 124 and / or the second opening 125.

[0081] A second shaft 126 is disposed transversely through the center of the internal space R1, and a first spring 128 is disposed around the second shaft 126. A first sealing valve 127 is connected to the end of the second shaft 126 on the side of the first opening 124 to seal the first opening 124. The first spring 128 applies force to the first sealing valve 127 in the direction of sealing the first opening 124. Furthermore, in the internal space R1, an odor component holder 130, such as an impregnating material for holding liquid odor components, is disposed around the first spring 128. In this way, by disposing the odor component holder 130 outside the first spring 128, the wind passing through the internal space R1 can easily reach the odor component holder 130, thereby increasing the amount of odor component emitted.

[0082] The second housing 112 has: an internal space R2; a first opening 131 and a second opening 132 that opens the internal space R2 to the outside and releases odor-containing air, a mixture of odor components and air, toward the ejection port 103; and a second spring 134 of elasticity, which is a movable part capable of opening and closing at least one of the first opening 131 and the second opening 132. The second housing 112 is also formed of the same material as the first housing 111.

[0083] The second spring 134 is disposed transversely through the center of the internal space R2. A second sealing valve 133 is installed at one end of the second spring 134 on the side of the first opening 131, sealing the first opening 131. The second spring 134 applies force to the second sealing valve 133 in the direction of sealing the first opening 131. Furthermore, in the internal space R2, a deodorant 135 for deodorizing residual odor components after spraying is disposed inside the second spring 134. The deodorant 135 may also be disposed in the internal space R1 or R2 of either the first housing 111 or the second housing 112. The deodorant 135 may also be disposed in multiple internal spaces.

[0084] Materials used as deodorant 135 can include activated carbon (coconut, fir, bamboo, resin, wood, fiber, coal, others), zeolite, layered compounds (lamellar silicates, alumina), porous silica (including mesoporous silica), etc. Furthermore, deodorant 135 can be in the form of powder, granules, fibers, molded parts, sheets (non-woven fabric, woven fabric), rods, plates, etc. Regarding the surface treatment of deodorant 135, activation treatment may or may not be performed, and surface functional group exposure treatment may or may not be performed (acidification, alkalization, polarization, non-polarization).

[0085] The first shaft 123 is movable in the extending direction from the interior of the connecting portion 110 toward the interior space R1. The second shaft 126 is connected to the front end of the first shaft 123 in the direction of the ejection port 103 via the first sealing valve 127, and is movable together with the first shaft 123 in the extending direction within the interior spaces R1 and R2. It should be noted that the first shaft 123 and the second shaft 126 can be linear motion mechanisms that move linearly in the opening and closing directions of the first opening 124 and the second opening 125.

[0086] The second shaft 126 is a movable part that can open and close the first opening 124 via the first sealing valve 127. In normal operation, the first sealing valve 127 is brought into contact with the first opening 124 by the first spring 128, thus sealing it. Similarly, the second sealing valve 133 is pressed against the first opening 131 by the force of the second spring 134, sealing the first opening 131 in normal operation. Therefore, the box 101 can prevent odor components from leaking from the first opening 124 and the first opening 131. It should be noted that the movable part involved in this technology can seal the first opening 124 and / or the second opening 125 in normal operation, and open the first opening 124 and / or the second opening 125 when the internal space R1 is open.

[0087] The first sealing valve 127 and the second sealing valve 133, which are part of the movable part, each have a tolerance absorption portion 129 on the surface that contacts the first shaft 123 or the second shaft 126. By utilizing the tolerance absorption portion 129, for example, even if there is a difference between the length of the first shaft 123 or the second shaft 126 in the extension direction and the length of the internal spaces R1 and R2 in the width direction, these errors can be absorbed, and the first opening 124 and the first opening 131 can be sealed. Therefore, the box 101 can prevent odor components from leaking from the first opening 124 and the first opening 131.

[0088] In this way, the tolerance absorbing part 129 becomes a structure that absorbs the tolerances of the sealed portion. Here, tolerance refers to manufacturing errors or deviations in dimensions related to sealing, such as the distance between the first open / closed position of the first opening 124 and the second open / closed position of the second opening 125, the distance between the first open / closed position of the first opening 131 and the second open / closed position of the second opening 132, the width of the opening, and the parallelism and length of the components. For example, even if the parallelism of the sealing surface is not achieved, the tolerance absorbing part 129 can maintain a sealed state by absorbing the tilting degree of the first shaft 123 or the second shaft 126 using the first spring 128 and the second spring 134.

[0089] It should be noted that, as an example, the first spring 128 is a helical spring, but it is not limited to this. Any elastic body capable of applying force to the first sealing valve 127 in the sealing direction of the first opening 124 can also be a leaf spring or the like. Similarly, as an example, the second spring 134 is also a helical spring, but it is not limited to this. Any elastic body capable of applying force to the second sealing valve 133 in the sealing direction of the first opening 131 is acceptable. Furthermore, an O-ring 136 can be provided on the surface of the first sealing valve 127 that contacts the first housing 111 to improve the sealing force. Similarly, an O-ring 136 can be provided on the surface of the second sealing valve 133 that contacts the second housing 112 to improve the sealing force.

[0090] The odor component retainer 130 holds the liquid odor component. The odor component retainer 130 is cylindrical, covering the side of the first shaft 123, but can also be rod-shaped, plate-shaped, or a hollow prism-shaped object. The liquid odor component can be, for example, essential oil or essential oil diluted with ethanol. The internal spaces R1 and R2 function as ventilation ducts through which air supplied from an air pump (not shown), one example of an air supply source, passes. The internal spaces R1 and R2 can each be a single space, or they can be divided into multiple spaces.

[0091] The liquid odor component adheres to and remains in a moist state on at least a portion of the inner surfaces of the interior spaces R1 and R2. For example, after the liquid odor component is filled into the interior spaces R1 and R2, by supplying a high-pressure gas such as air into the interior spaces R1 and R2 for a predetermined time, the remaining liquid odor component can be sprayed out, causing the odor component to adhere to the inner surfaces of the interior spaces R1 and R2 in a moist state.

[0092] The odor supply device 100 can control the emission of multiple odor components by arranging odor component holders 130, which hold different odor components, in the internal spaces R1 and R2 of each box 101. It should be noted that the liquid odor components held in the internal spaces R1 and R2 of each box 101 can be all the same, or some or all different.

[0093] The odor component retainer 130 can be made of an organic polymer material to facilitate the impregnation of the liquid odor component. Examples of such organic polymer materials include, for instance, any one or a mixture of polyvinyl chloride, polyethylene, phenolic resin, olefin resin, nylon, polyester, synthetic rubber, silicone resin, natural rubber, protein, nucleic acid, lipid, and polysaccharides. However, the odor component retainer 130 is not limited to these examples. For instance, it can also use polymer resins such as acrylic resin, polyurethane resin, ABS resin, polyetheretherketone (PEEK) resin, polyacetal (POM) resin, fluoropolymer resin, cyclic olefin polymer resin, and polyimide resin; metals such as stainless steel and aluminum; inorganic crystals such as quartz; or one or more materials such as glass. Furthermore, the odor component retainer 130 can also be formed as a porous material. Porous materials include mesh structures, cork, mesoporous silica, and calcium carbonate. In addition to porous materials, the odor component retainer 130 can also use fibrous structures, layered structures (clay minerals, etc.), ceramics, etc. In addition, the surface of box 101 may also be formed of any one or a combination of materials selected from low gas permeability resin, organic polymer, organic low molecular weight, organometallic, metal, metal film.

[0094] It should be noted that, although not shown, the first housing 111 or the second housing 112 may also have a reading unit capable of reading the contents of the box 101. For example, a label, barcode, etc. may also be provided on the surface of the first housing 111 or the second housing 112.

[0095] Alternatively, the box 101 can be manufactured using a 3D printer, for example. In this case, materials suitable for 3D printers can be selected as the constituent materials of the box 101.

[0096] (1-3) Drive Mechanism Section

[0097] Next, an example of the configuration of the drive mechanism 102 included in the odor providing device 100 according to this embodiment will be described.

[0098] As described above, the drive mechanism section 102 includes a drive mechanism housing section 114. The drive mechanism section 102 is connected to the first shaft 123 and the second shaft 126, which are movable parts, and functions as a drive mechanism to drive them. It should be noted that the drive mechanism housing section 114 is cylindrical, but the shape of the drive mechanism section involved in this technology is not limited to a cylindrical shape, and can be made into, for example, a cylinder, a cuboid, a cube, or other suitable shapes to suit the odor component retaining component.

[0099] like Figure 3As shown, the drive mechanism section 102 includes a pusher 141 connected to the first shaft 123 inside the drive mechanism housing section 114, and a shape memory alloy SMA (SEM) wire serving as the drive source for the pusher 141. The rear end of the pusher 141 is fixed to a drive mechanism fixing section 142 located at the rear end inside the drive mechanism housing section 114. Near the front end of the pusher 141, there is an SMA sliding section 143 for sliding back and forth on the shape memory alloy SMA. Furthermore, the entire drive mechanism section 102 is fixed by a support section 144 mounted below the drive mechanism housing section 114. A power supply wiring 145 is connected to the rear end of the shape memory alloy SMA located inside the drive mechanism fixing section 142.

[0100] The pusher 141 is movable along the extension direction inside the drive mechanism housing 114 by the expansion and contraction of the shape memory alloy SMA. The shape of the pusher 141 can be any shape that is pressed into the first shaft 123, or it can be cylindrical, conical, cylindrical, prism, etc.

[0101] The drive mechanism receiving section 114 has a magnet (not shown) at the front of the box 101 side, and can be detachably connected to the rear of the connecting section 110 of the box 101 via this magnet. In this way, the box 101 can be easily loaded and unloaded from the drive mechanism section 102 by magnetically engaging the loading and unloading section. It should be noted that the loading and unloading section can be loaded and unloaded via a drive source and / or a magnetic unit, or it can be connected to a valve. Furthermore, the power for linear motion from the drive mechanism section 102 can be transmitted to the box 101. Therefore, the box 101 does not need to have a drive source.

[0102] The shape memory alloy SMA (Small Shape Memory Alloy) folds back in a U-shape at the SMA sliding portion 143 near the front end of the pusher 141, passing through the interior of the pusher 141, and its two ends are fixed to the drive mechanism fixing portion 142 located at the rear end of the pusher 141. In the drive mechanism portion 102, by energizing the shape memory alloy SMA, which serves as the drive source, through the wiring 145, the shape memory alloy SMA slides and retracts via the SMA sliding portion 143. When the shape memory alloy SMA retracts, the drive mechanism fixing portion 142 connected to the end of the shape memory alloy SMA causes the pusher 141 to move forward toward the box 101. As the pusher 141 moves forward, the first shaft 123 connected to the front end of the pusher 141 pushes the first sealing valve 127 forward. Furthermore, since the first sealing valve 127 is pushed forward, the second shaft 126 connected to the first sealing valve 127 pushes the second sealing valve 133 forward. It should be noted that the drive mechanism 102 is a mechanism that does not apply a load to the shape memory alloy SMA when it is not energized. In addition, as an example, a shape memory alloy SMA is used, but it is not limited to this. It can also be an elastic body or the like that can make the push member 141 movable in the front-back direction.

[0103] Furthermore, the actuator used as the driving source is not limited to shape memory alloy SMA; any linear motion mechanism that causes the pressing member 141 to move linearly is acceptable, such as a motor, solenoid, linear sliding type, pneumatic type (air pump type), or small electromagnet. Here, the linear motion mechanism includes not only the case where a single component moves in a linear direction, but also the case where a portion of a group of connected components moves in a linear direction.

[0104] (2) Example of operation of odor supply device

[0105] Next, refer to Figure 3 and Figure 4 An example of the action of releasing odor-containing air from the odor supply device 100 will be explained. Figure 4 This is a side sectional view showing an example of the operation of the odor providing device 100.

[0106] First, an air pump (not shown) connected to the air inlet of the drive mechanism housing 114 is turned on, and air introduced from the air pump is sent into the interior of the drive mechanism housing 114. This air pump is one type of air supply source, driven by electricity supplied from a primary or secondary battery, and introduces air into the ventilation path. The air pump can also be, for example, a diaphragm pump that draws and compresses air by supplying alternating current to a piezoelectric element, causing the diaphragm to deform.

[0107] Next, when an electric current is applied to the shape memory alloy SMA passing through the interior of the pusher 141, the shape memory alloy SMA retracts from the pusher 141 toward the rear. As a result, the drive mechanism fixing part 142 connected to the end of the pusher 141 causes the pusher 141 to move linearly toward the front of the odor supply device 100.

[0108] Therefore, the first shaft 123 installed in front of the pusher 141 also moves forward, and the first shaft 123 presses the first sealing valve 127 forward, making the first sealing valve 127 movable forward. At this time, the first spring 128 is pressed against the front side by the first shaft 123 and contracts.

[0109] When the first sealing valve 127 is movable to the forward side, the first opening 124, which is sealed by the first sealing valve 127, opens and opens the internal space R1 to the outside. When the first opening 124 is open, the air W supplied to the drive mechanism receiving part 114 passes through the connecting part 110 and flows into the internal space R1 from the first opening 124.

[0110] The air W flowing into the interior space R1 mixes with the odor component contained in the odor component holder 130 within the interior space R1, creating a mixed odor-containing air W. At this time, since the odor component holder 130 is disposed outside the first spring 128, as shown in region r1, the wind passing through the interior space R1 easily encounters the odor component holder 130, thereby increasing the amount of odor component emitted.

[0111] Furthermore, since the first shut-off valve 127 is movable, the second shaft 126 installed in front of the first shut-off valve 127 is also movable forward. The second shaft 126 presses the second shut-off valve 133 forward, making the second shut-off valve 133 movable forward. At this time, the second spring 134 is compressed from the second shut-off valve 133 by being pressed against the front side.

[0112] When the second sealing valve 133 is movable forward, the first opening 131, which is connected to the second opening 125 sealed by the second sealing valve 133, opens and opens the internal space R2 to the outside. When the first opening 131 is open, the odor-containing air W, which is mixed with odor components in the internal space R1, flows through the second opening 125 and into the internal space R2 from the first opening 131.

[0113] Then, the odorous air W that flows into the interior space R2 passes through the second opening 132 and is released to the user outside through the nozzle 103.

[0114] After the odorous air W is released to the outside, if the power to the actuator is cut off, the shape memory alloy SMA, which is in a non-energized state, is released from its contracted state. Then, under the restoring force of the contracted first spring 128, the first shaft 123 and the first sealing valve 127 are pushed to their initial positions, thereby returning the pusher 141 to its normal initial position. Furthermore, the first sealing valve 127 and the second sealing valve 133, aided by the restoring forces of the first spring 128 and the second spring 134, slide rearward respectively until they contact and seal the first opening 124 and the first opening 131. Using this sliding pressure cap mechanism composed of the first sealing valve 127 and the second sealing valve 133, the first opening 124 and the first opening 131 can be sealed under normal conditions. At this time, using the tolerance absorption part 129, even if a tolerance is present, the first opening 124 and the first opening 131 can still be sealed separately.

[0115] It should be noted that the odor supply device 100 adjusts the elastic force of the first spring 128 and the second spring 134 sufficient to seal and the movement of the push member 141 sufficient to open by adjusting the force and displacement of the first spring 128, the second spring 134, the shape memory alloy SMA and the actuator, thereby adjusting the tolerance absorption amount of the tolerance absorption part 129.

[0116] In addition, the odor supply device 100 may be a mechanism that opens and closes the first opening 124 and then the first opening 131 by a time difference in order to increase the ejection force from the ejection hole 103, or it may be a mechanism that opens and closes the first opening 124 and the first opening 131 simultaneously in order to improve responsiveness.

[0117] Here, the odor component sprayed from the odor component holder 130 adheres to the walls of the internal spaces R1 and R2, etc. If it is a strong odor component, it will produce a lingering fragrance. As a result, when the odor is provided again, the odor sprayed mixes with the lingering fragrance and fails to provide the user with the desired odor, or an unpleasant odor is produced due to the lingering fragrance, which becomes a problem.

[0118] In response to this, the odor supply device 100 with box 101 according to this embodiment has a deodorant 135 in the internal space R2 of the second housing 112. Therefore, by deodorizing the residual fragrance in the internal space R2, the residual fragrance is prevented from lingering, thereby preventing it from mixing with other odors.

[0119] Since the load direction of the spring force of the first spring 128 and the second spring 134 is unidirectional, the first sealing valve 127 and the second sealing valve 133, which are movable parts of the housing 101, do not produce a reaction action. The spring force directly becomes the sealing force of the first opening 124 and the first opening 131. As a result, the sealing force of the first opening 124 and the first opening 131 can be increased, thereby enabling the opening and closing of the first opening 124 and the first opening 131 with less force.

[0120] Box 101 utilizes a first spring 128 and a second spring 134 to keep the first sealing valve 127 and the second sealing valve 133 sealed during assembly. Furthermore, since box 101 can open and close the first opening 124 and the first opening 131 with relatively little force, it can be opened and closed using only air pressure.

[0121] In box 101, since the first opening 124, the second opening 125, the first shaft 123, the second shaft 126, the first sealing valve 127, the first spring 128, the second sealing valve 133, the second spring 134, the odor component retainer 130, and the deodorant 135 are arranged in the same cylindrical space that is substantially parallel to the direction in which multiple shells are stacked to form a stacked structure, the internal spaces R1 and R2 can be saved. As a result, box 101 can be miniaturized.

[0122] Furthermore, since the internal spaces R1 and R2 of box 101 can be sealed to a certain pressure, the valve in the air supply path section can be opened after the pump or other means for ventilation is turned on. As a result, the odor supply device 100 keeps the intake and exhaust of air in a unidirectional manner, preventing backflow, protecting the equipment, and preventing contamination (mixing of odor components).

[0123] Furthermore, by utilizing the tolerance absorption structure of the tolerance absorption section 129, it is possible to structurally control which of the first opening section 124, serving as the air supply path, and the first opening section 131, serving as the odor-containing air release path, is opened first. Thus, the odor supply device 100 can prevent backflow, protect the equipment, and prevent contamination by opening the first opening section 124 after opening the first opening section 131, or closing the first opening section 124 after closing the first opening section 131.

[0124] It should be noted that, in order to prevent gas permeation, the connecting portion 110, the first housing 111, the second housing 112, and the fitting portion of the front end portion 113 of the housing can be coated with an oil-sealing material or an elastic material such as silicone rubber or fluororubber. Alternatively, it can be a material composed of a combination of oil-sealing material and elastic material. For the same purpose, the surface of the housing 101 can be formed of any one or a combination of several of the following materials: low-gas-permeability fluororesin, polymer film, SAM film, LB film, organic polymers or organic low-molecular-weight compounds, organometallic materials, metals, metal films, etc. Metals or metal films can be used for metal vapor deposition. Furthermore, the inner wall surface of the housing 101 can also be formed of metal.

[0125] (3) Examples of box variations

[0126] Next, refer to Figure 5 and Figure 6 A modified example of box 101 will be explained. Figure 5 This is a side sectional view showing a modified example of the box 101 according to this embodiment. The difference between the box 151 and the box 101 in this modified example is that the number of shells is increased from two to four. The other configurations of the box 151 are the same as those of the box 101, and the same reference numerals are used to describe the same configurations.

[0127] like Figure 5 As shown, the box 151 includes: a connecting portion 110, detachably connected to the drive mechanism portion 102; a first housing 111 connected to the connecting portion 110; a second housing 112 connected to the first housing 111; a third housing 152 connected to the second housing 112; a fourth housing 153 connected to the third housing 152; and a housing front end portion 113 connected to the fourth housing 153. The first housing 111, the second housing 112, the third housing 152, the fourth housing 153, and the housing front end portion 113 are configured in a stacked structure and connected together.

[0128] The first housing 111, the second housing 112, and the third housing 152 have the same configuration. That is, the first housing 111, the second housing 112, and the third housing 152 each have a second shaft 126, a first sealing valve 127, a first spring 128, and an odor component retainer 130 in their respective internal spaces R1, R2, and R3.

[0129] The fourth housing 153 has a second sealing valve 133, a second spring 134 and a deodorant 135 in its internal space R4.

[0130] Next, refer to Figure 5 An example of the action of releasing odor-containing air from the odor supply device that connects the box 151 to the drive mechanism 102 will be described.

[0131] Similar to the odor-providing device 100, when energized, the shape memory alloy SMA connected to the pusher 141 retracts from the pusher 141 to the rearward side. As a result, the pusher 141 moves linearly towards the front of the box 151.

[0132] Therefore, the first shaft 123 installed in front of the pusher 141 also moves forward, and the first shaft 123 presses the first sealing valve 127 of the internal space R1 forward, and the first sealing valve 127 moves forward. At this time, the first spring 128 of the internal space R1 is pressed against the front side from the first shaft 123 and contracts.

[0133] When the first sealing valve 127 of the internal space R1 is movable to the forward side, the first opening 124, which is sealed by the first sealing valve 127, opens and opens the internal space R1 to the outside. When the first opening 124 is open, the air W supplied to the drive mechanism receiving part 114 flows into the internal space R1 through the connecting part 110 and from the first opening 124.

[0134] The air W flowing into the interior space R1 mixes with the odor components contained in the odor component retainer 130 within the interior space R1 to create a mixed odor-containing air W.

[0135] Furthermore, because the first sealing valve 127 of the internal space R1 is movable, the second shaft 126 installed in front of the first sealing valve 127 is also movable forward. The movable second shaft 126 presses the first sealing valve 127 of the internal space R2 forward, making the first sealing valve 127 of the internal space R2 movable forward. At this time, the first spring 128 of the internal space R2 is pressed against the front side from the first shaft 123 and contracts.

[0136] Similarly, because the first sealing valve 127 of the internal space R2 is movable, the second shaft 126 installed in front of the first sealing valve 127 is also movable forward. The movable second shaft 126 presses the first sealing valve 127 of the internal space R3 forward, making the first sealing valve 127 of the internal space R3 movable forward. At this time, the first spring 128 of the internal space R3 is pressed against the front side from the first shaft 123 and contracts.

[0137] Thus, firstly, the first opening 124 of the interior space R2 opens, opening the interior space R2 to the outside. When the first opening 124 of the interior space R2 is open, the odor-containing air W, which is mixed with odor components in the interior space R1, flows into the interior space R2 through the second opening 125 of the interior space R1. The air W flowing into the interior space R2 mixes with the odor components contained in the odor component holder 130 within the interior space R2, creating a mixed odor-containing air W.

[0138] Next, the first opening 124 of the interior space R3 opens, opening the interior space R3 to the outside. When the first opening 124 of the interior space R3 is open, the odor-containing air W, which is mixed with odor components in the interior space R2, flows into the interior space R3 through the second opening 125 of the interior space R2. The air W flowing into the interior space R3 mixes with the odor components contained in the odor component holder 130 in the interior space R3, creating a mixed odor-containing air W.

[0139] Then, because the first sealing valve 127 of the internal space R3 is movable, the second shaft 126 of the internal space R3, which is installed in front of the first sealing valve 127, is also movable forward. The movable second shaft 126 presses the second sealing valve 133 of the internal space R4 forward, making the second sealing valve 133 movable forward. At this time, the second spring 134 of the internal space R4 is compressed and retracted from the second sealing valve 133 by being pressed against the front side.

[0140] When the second sealing valve 133 is movable forward, the first opening 131, which communicates with the second opening 125 of the internal space R3 sealed by the second sealing valve 133, opens, thus opening the internal space R4 to the outside. When the first opening 131 is open, the odor-containing air W, which is mixed with odor components in the internal space R3, flows through the second opening 125 of the internal space R3 and into the internal space R4 from the first opening 131.

[0141] Then, the odorous air W that flows into the interior space R4 passes through the second opening 132 and is released to the user outside through the nozzle 103.

[0142] After the odorous air W is released to the outside, if the power to the actuator is cut off, the shape memory alloy SMA, which is in a non-energized state, is released from its contracted state. Under the restoring force of the contracted first spring 128, the first shaft 123 and the first sealing valve 127 are pushed to their initial positions, thereby returning the pusher 141 to its normal initial position. Furthermore, each of the first sealing valves 127 and the second sealing valve 133 slides rearward with the restoring force of each of the first springs 128 and 134 until it contacts and seals each of the first openings 124 and 131. Using this sliding pressure cap mechanism composed of the first sealing valves 127 and 133, each of the first openings 124 and 131 can be sealed under normal conditions. At this time, using the tolerance absorption part 129, even if a tolerance is present, each of the first openings 124 and 131 can be sealed separately.

[0143] By providing a housing 151 in the odor-providing device according to this technology, the same effect as that of the odor-providing device 100 can be achieved. Since a deodorant 135 is provided in the internal space R4 of the fourth housing 153, the residual fragrance in the internal space R4 is deodorized, preventing fragrance retention and thus preventing mixing with other odors. Furthermore, since the housing 151 has multiple odor component holders 130, it can provide the user with air W mixed with multiple odors. It should be noted that the number of housings is not limited to this embodiment; it can also be three or five or more. Additionally, the number and placement of the odor component holders 130 and the deodorant 135 are not limited to this embodiment; they can be any number and can be placed in any housing.

[0144] (4) Variations of odor component retainers

[0145] Next, refer to Figure 6 A modified example of the odor component retainer 130 will be described. Figure 6 This is a partially enlarged view showing a modified example of the odor component retainer 130.

[0146] Figure 6 A is a partially enlarged view of odor component retainer 161, a first variation of odor component retainer 130. (See image for reference.) Figure 6 As shown in Figure A, the odor component holder 161 has a through hole 162 on its side for air to pass through. As a result, the odor component holder 161 has good air permeability, which allows the air W passing through the internal space to be forced through the through hole 162 of the odor component holder 161 and easily mix with the odor component.

[0147] Figure 6 B is a partially enlarged view of odor component retainer 163, a second variation of odor component retainer 130. (See image below.) Figure 6 As shown in B, the odor component retainer 163 is formed as a porous material with good air permeability. As a result, the odor component retainer 163 has good air permeability and can also force the air W passing through the interior space to pass through the interior of the odor component retainer 163 and easily mix with the odor component.

[0148] (5) Examples of variations of closed structures

[0149] Next, refer to Figure 7 and Figure 8 A modified example of the sealed structure of the first opening 124 of the odor supply device 100 will be described. Figure 7 This is a side sectional view showing a first modified example of the sealed structure of the first opening 124. Figure 8 This is a side sectional view showing a second modified example of the sealed structure of the first opening 124.

[0150] like Figure 7 A and Figure 7 As shown in B, a trapezoidal first sealing valve 173 that can abut against the shaped surface of the housing 171 can be used in the first opening 172 formed in the conical housing 171. Additionally, as... Figure 8 A and Figure 8 As shown in B, a ball-shaped first sealing valve 181 can be pressed against a first opening 172 formed in a conical housing 171 for use. These can also be applied to a second opening 125. Furthermore, the shape of the sealing valve is not limited to these; it can be any shape as long as it can seal the opening.

[0151] Furthermore, the odor-providing device 100 may also form a protrusion 404k and a protrusion movement groove into either the connecting portion 110 of the box 101 or the drive mechanism portion 102, thereby having a locking mechanism for locking the box 101 and the drive mechanism portion 102. This locking mechanism can seal the internal space R1 under normal conditions, and open the internal space R1 when assembled to an external device, as the interior of the box 101 communicates with the interior of the drive mechanism portion 102.

[0152] Using the aforementioned locking mechanism, when the box 101 is in its normal, standalone state, the internal space R1 can be sealed to prevent odor components from leaking from the rear end of the box 101. Furthermore, the box 101 and the drive mechanism 102 can be connected in the sealed state, thus preventing odor component leakage even after connection.

[0153] 2. Second Implementation Method

[0154] (1) Example of box construction

[0155] Next, refer to Figure 9 Hereinafter, an example of the configuration of the odor providing device 200 according to the second embodiment of the present technology will be described. Figure 9 This is a side cross-sectional view showing an example of the configuration of the odor-providing device 200 according to this embodiment. The odor-providing device 200 differs from the odor-providing device 100 according to the first embodiment in that the shape of the housing and the arrangement of the odor component holder 130 and the deodorant 135 are different. The other configurations of the odor-providing device 200 are the same as those of the odor-providing device 100.

[0156] like Figure 9 As shown, the odor supply device 200 according to this embodiment includes: a cylindrical box 201 that serves as an odor component holding member, with its front end side inclined; a cylindrical drive mechanism 102; and an ejection hole 203 formed at the front end of the box 201, which releases odor-containing air containing odor components to the outside.

[0157] The box 201 includes: a connecting portion 210 detachably connected to a drive mechanism portion 102, which is connected to and drives a movable portion capable of opening and closing an opening; a first housing 211 connected to the connecting portion 210; a second housing 212 connected to the first housing 211; and a housing front end portion 213 connected to the second housing 212. The first housing 211, the second housing 212, and the housing front end portion 213 are configured in a stacked structure and connected together. The drive mechanism portion 102 includes a drive mechanism receiving portion 114 for housing the drive mechanism.

[0158] The connecting portion 210 is screwed into the first housing 211 via a threaded cutting portion 221, forming a sealed contact portion with the first housing 211 on the inclined surface 222. The connecting portion 210 internally includes a first shaft 123 serving as an actuating shaft. Similarly, the first housing 211 and the second housing 212, as well as the second housing 212 and the front end portion 113 of the housing, are screwed into each other via threaded cutting portions 121, forming sealed contact portions on the inclined surface 222. The box 201 uses the threaded cutting portions 221 and the inclined surface 222 to seal each fitting portion, preventing odor components from leaking from these fitting portions.

[0159] The first housing 211 has: an internal space R11; a first opening 224 and a second opening 225 that open the internal space R1 to the outside and release odor-containing air, which is a mixture of odor components and air, toward the ejection port 203; and a second shaft 126 as an actuating shaft and a first spring 128 as an elastic body, the second shaft 126 and the first spring 128 being movable parts that are movable in a manner capable of opening and closing at least one of the first opening 224 and the second opening 225.

[0160] In box 201, the first opening 224, the second opening 225, the second shaft 126, the first spring 128, and the odor component retainer 130 are arranged substantially parallel to the direction in which the first housing 211, the second housing 212, and the front end portion 213 of the housing are stacked. The odor component retainer 130 may also be arranged in multiple internal spaces. It should be noted that the first spring 128 may also be subjected to force in the sealing direction of the first opening 224 and / or the second opening 225.

[0161] A second shaft 126 is disposed transversely through the center of the internal space R11, and a first spring 128 is disposed around the second shaft 126. A first sealing valve 127 is connected to the end of the second shaft 126 on the side of the first opening 224 to seal the first opening 224. The first spring 128 applies force to the first sealing valve 127 in the direction of sealing the first opening 224. Furthermore, in the internal space R11, an odor component holder 130, such as an impregnating material for holding liquid odor components, is disposed around the first spring 128. In this way, by disposing the odor component holder 130 outside the first spring 128, the wind passing through the internal space R1 can easily reach the odor component holder 130, thereby increasing the amount of odor component emitted.

[0162] The second housing 212 has: an internal space R12; a first opening 231 and a second opening 232 that open the internal space R12 to the outside and release odor-containing air, which is a mixture of odor components and air, toward the ejection port 203; and a second spring 134 of an elastic body, which is a movable part that is movable in a manner capable of opening and closing at least one of the first opening 231 and the second opening 232.

[0163] The second spring 134 is arranged to pass through the center of the internal space R2. A second sealing valve 133 is installed at one end of the second spring 134 on the side of the first opening 231 to seal the first opening 231.

[0164] The second spring 134 applies force to the second sealing valve 133 in the direction of sealing the first opening 231.

[0165] Furthermore, within the internal space R12, a deodorizing agent 135 for deodorizing residual odor components after spraying is disposed inside the second spring 134. In this embodiment, the deodorizing agent 135 is disposed at a position away from the ventilation path of the airflow passing through the internal space R12. Here, if deodorization is performed immediately after the odor-containing air is sprayed to the outside, the sprayed odor components become meaningless. Therefore, in order to efficiently remove only the odor components remaining in the internal space R12, the deodorizing agent 135 is preferably disposed as far away from the second opening 232 as possible and as close as possible to the center of the internal space R12. It should be noted that the deodorizing agent 135 may also be disposed within the internal space R11 or R12 of either the first housing 211 or the second housing 212. The deodorizing agent 135 may also be disposed within multiple internal spaces.

[0166] (2) Example of operation of odor supply device

[0167] Next, refer to Figure 10 and Figure 11 An example of the action of releasing odor-containing air from the odor supply device 200 will be explained. Figure 10This is a side cross-sectional view showing the odor-providing device 200 with its opening closed. Figure 11 This is a side cross-sectional view showing the odor-providing device 200 with its opening open.

[0168] Similar to the odor supply device 100 according to the first embodiment, firstly, an air pump (not shown) connected to the air inlet of the drive mechanism housing 114 is turned on, and air introduced from the air pump is sent into the interior of the drive mechanism housing 114. This air pump is one type of air supply source, driven by electricity supplied from a primary or secondary battery, and introduces air into the ventilation path.

[0169] Next, when the shape memory alloy SMA connected to the pusher 141 is energized, the shape memory alloy SMA retracts from the pusher 141 to the rearward side. As a result, the pusher 141 moves linearly towards the front of the odor supply device 200.

[0170] Therefore, the first shaft 123 installed in front of the pusher 141 also moves forward, and the first shaft 123 presses the first sealing valve 127 forward, making the first sealing valve 127 movable forward. At this time, the first spring 128 is pressed against the front side by the first shaft 123 and contracts.

[0171] When the first sealing valve 127 is movable to the forward side, the first opening 224, which is sealed by the first sealing valve 127, opens and opens the internal space R11 to the outside. When the first opening 224 is open, the air W supplied to the drive mechanism receiving part 114 passes through the connecting part 210 and flows into the internal space R11 from the first opening 224.

[0172] The air W flowing into the interior space R11 mixes with the odor component contained in the odor component holder 130 within the interior space R11, creating a mixed odor-containing air W. At this time, since the odor component holder 130 is disposed outside the first spring 128, as shown in region r11, the wind passing through the interior space R11 easily encounters the odor component holder 130, thereby increasing the amount of odor component emitted.

[0173] Furthermore, since the first shut-off valve 127 is movable, the second shaft 126 installed in front of the first shut-off valve 127 is also movable forward. The second shaft 126 presses the second shut-off valve 133 forward, making the second shut-off valve 133 movable forward. At this time, the second spring 134 is compressed from the second shut-off valve 133 by being pressed against the front side.

[0174] When the second sealing valve 133 is movable to the forward side, the first opening 231, which is connected to the second opening 225 sealed by the second sealing valve 133, opens and opens the internal space R12 to the outside. When the first opening 231 is open, the odor-containing air W, which is mixed with odor components in the internal space R11, flows through the second opening 225 and into the internal space R12 from the first opening 231.

[0175] Then, the odorous air W that flows into the interior space R12 passes through the second opening 232 and is released to the user outside through the nozzle 203.

[0176] After the odorous air W is released to the outside, if the power to the actuator is cut off, the shape memory alloy SMA, which is in a non-energized state, is released from its contracted state. Under the restoring force of the contracted first spring 128, the first shaft 123 and the first sealing valve 127 are pushed to their initial positions, thereby returning the pusher 141 to its normal initial position. Furthermore, the first sealing valve 127 and the second sealing valve 133 slide backwards respectively with the restoring force of the first spring 128 and the second spring 134 until they contact and seal the first opening 224 and the first opening 231. Using this sliding pressure cap mechanism composed of the first sealing valve 127 and the second sealing valve 133, the first opening 224 and the first opening 231 can be sealed under normal conditions. At this time, using the tolerance absorption part 129, even if a tolerance is present, the first opening 224 and the first opening 231 can still be sealed separately.

[0177] The odor supply device 200 with housing 201 according to this embodiment can have the same effect as the odor supply device 100 according to the first embodiment. Furthermore, according to the odor supply device 200, since the deodorant 135 is disposed at a position away from the ventilation flow path of the air passing through the interior space R12, it can efficiently remove only the odor components retained in the interior space R12.

[0178] 3. Third Implementation Method

[0179] Next, refer to Figure 12 and Figure 13 Hereinafter, an example of the configuration of the odor providing unit 300 according to the third embodiment of the present technology will be described. Figure 12 This is a perspective view showing an example of the configuration of the odor providing unit 300 according to this embodiment. Figure 13 A is a perspective view showing the ventilation flow path of the odor providing unit 300. Figure 13B is a partial cross-sectional view showing an example of the configuration of the odor providing unit 300. The odor providing unit 300 is arranged in a manner in which a plurality of odor providing devices 100 according to the first embodiment are arranged. The arrangement of the odor providing devices 100 can be planar, or it can be arranged in a stepped manner, or in an opposing arrangement, etc., on a curved surface that is not in the same plane.

[0180] like Figure 12 As shown, the odor providing unit 300 according to this embodiment includes: a plate-shaped connecting portion 310, a connecting box 101, and a drive mechanism portion 102; a plurality of boxes 101 arranged and connected on the upper surface of the connecting portion 310; a plurality of drive mechanism portions 102 disposed opposite to each box 101 on the lower surface of the connecting portion 310; a substrate 316 connected to the lower part of the drive mechanism portion 102 via a bio-metallic material (BMF) connected to a shape memory alloy SMA; and a pump 315 that blows air between the connecting portion 310 and the drive mechanism portion 102. It should be noted that the odor providing unit 300 includes one pump 315 that blows air to the plurality of boxes 101, but it may also include a pump 315 that blows air to each box 101 individually, or it may include multiple pumps that blow air to one box 101.

[0181] The drive mechanism section 102 has a drive mechanism housing section 114 that houses the drive mechanism. The odor supply unit 300 has four boxes 101 arranged along the short side of the connecting section 310 and seven boxes 101 arranged along the long side, but the number of boxes 101 is not limited to this and can be set to any number. Furthermore, the odor supply unit 300 can use either a box 101 with only one housing or a box 101 with multiple housings arranged in a stacked structure, or both.

[0182] like Figure 13 As shown in A, in the odor supply unit 300, when air is supplied from the pump 315 to the upper part of the drive mechanism housing 114, the air diffuses throughout the entire connecting part 310. Then, by opening the first opening 124 of each box 101, the diffused air is blown into the internal space R1 of each box 101.

[0183] like Figure 13 As shown in Figure B, the drive mechanism 102 of the odor supply unit 300 includes an adjustment valve 321 that adjusts the amount of air supplied from the pump 315 to the housing 101. Furthermore, a locking mechanism 322 is provided between the housing 101 and the drive mechanism 102 to prevent the connection from detaching due to the air pressure of the supplied air. Additionally, a movable hole 323 for biometal is formed at the lower end of the drive mechanism 102. The movable hole 323 is bonded with an adhesive that allows the biometal to move and blocks it to prevent air leakage.

[0184] The odor providing unit 300 according to this embodiment can have the same effect as the odor providing device 100 according to the first embodiment. Furthermore, according to the odor providing unit 300, by making the desired box among the plurality of boxes 101 that mix multiple odors movable, various odors can be provided to the user.

[0185] 4. Fourth Implementation Method

[0186] (1) Example of box construction

[0187] Next, refer to Figure 14 Hereinafter, an example of the configuration of the odor providing device 400 according to the fourth embodiment of the present technology will be described. Figure 14 A is a side sectional view showing an example of the configuration of the odor providing device 400 according to this embodiment. Figure 14 B is a side sectional view showing an example of the operation of the odor providing device 400. The difference between the odor providing device 400 and the odor providing device 100 according to the first embodiment is that one housing of the device has a mechanism for opening and closing two openings. The other configurations of the odor providing device 400 are the same as those of the odor providing device 100.

[0188] like Figure 14 As shown in Figure A, the odor supply device 400 of this embodiment includes a cylindrical box 401 with a flat front surface and a flat rear surface. Furthermore, similar to the odor supply device 100 of the first embodiment, the odor supply device 400 includes a cylindrical drive mechanism 102 and a spray hole 103 formed at the front end of the box 401, which releases odor-containing air containing odor components to the outside.

[0189] The box 401 has a first housing 411 connected to the connecting part 210, which is detachably connected to the drive mechanism part 102 that drives the movable part. The connecting part 210 of the box 401 has a first shaft 412 inside it, which serves as an actuation shaft. The first shaft 412 is mounted in front of the push member 141 inside the drive mechanism part 102.

[0190] The first housing 411 has: an internal space R21; a first opening 413 and a second opening 414, which open the internal space R21 to the outside and release odor-containing air, which is a mixture of odor components and air, toward the ejector hole 103; a first sealing valve 415, which can open and close the first opening 413; and a second sealing valve 416, which can open and close the second opening 414.

[0191] Furthermore, the first housing 411 includes: two first support pillars 417 and two second support pillars 418 serving as movable parts for moving the first shut-off valve 415 and the second shut-off valve 416; and a support pillar actuation guide rail 419 disposed between the first support pillars 417 and the second support pillars 418, allowing the first support pillars 417 and the second support pillars 418 to move in directions orthogonal to the movable directions of the first shut-off valve 415 and the second shut-off valve 416. Both ends of the support pillar actuation guide rail 419 are fixed to the inner wall of the first housing 411.

[0192] Furthermore, the first housing 411 has a first spring 420, which, in normal operation, applies force to the first sealing valve 415 and the second sealing valve 416 in a direction that presses against the first opening 413 and the second opening 414, respectively. In the internal space R21, an odor component retainer 130, such as an impregnating material for retaining liquid odor components, is arranged, for example, surrounding the first spring 420.

[0193] One end of each of the two first support pillars 417 is connected to the first shut-off valve 415, and the other end is in contact with the support pillar actuation guide rail 419 in a manner that allows it to slide on the support pillar actuation guide rail 419. One end of each of the two second support pillars 418 is connected to the second shut-off valve 416, and the other end is in contact with the support pillar actuation guide rail 419 in a manner that allows it to slide on the support pillar actuation guide rail 419.

[0194] Figure 14 When A is facing the paper, the other ends of the first pillar 417 and the second pillar 418 on the left are connected by a connecting part CL that is slidably mounted on the pillar actuation guide rail 419. Figure 14 When A is facing the paper, the other ends of the first pillar 417 and the second pillar 418 on the right side are connected by a connecting part CR that is slidably mounted on the pillar actuation guide rail 419.

[0195] In box 401, when the first opening 413 and the second opening 414 open, the first spring 420 contracts, and when the connecting parts CL and CR at the ends of the two first pillars 417 and the two second pillars 418 are movable in a direction away from each other on the pillar actuation guide rail 419, the first sealing valve 415 and the second sealing valve 416 in the internal space R21 are movable in a direction close to each other.

[0196] The deodorant 135, which deodorizes the residual odor components after spraying, can be placed in the internal space R21 or in the internal space of other housings connected to the first housing 411.

[0197] (2) Example of operation of odor supply device

[0198] Next, refer to Figure 14 A and Figure 14 Example B illustrates the action of releasing odor-containing air from the odor supply device 400. Figure 14 A is a side sectional view showing the odor providing device 400 with its opening closed. Figure 14 B is a side sectional view showing the odor providing device 400 with its opening open.

[0199] Similar to the odor supply device 100 according to the first embodiment, firstly, an air pump (not shown) connected to the air inlet of the drive mechanism housing 114 is turned on, and air introduced from the air pump is sent into the interior of the drive mechanism housing 114. This air pump is one type of air supply source, driven by electricity supplied from a primary or secondary battery, and introduces air into the ventilation path.

[0200] Next, when the shape memory alloy SMA connected to the pusher 141 is energized, the shape memory alloy SMA retracts from the pusher 141 to the rearward side. As a result, the pusher 141 moves linearly towards the front of the odor supply device 400.

[0201] Therefore, the first shaft 412 installed in front of the pusher 141 is also movable in the forward movable direction D1. The first shaft 412 presses the first sealing valve 415 forward, and the first sealing valve 415 is movable in the movable direction D1.

[0202] When the first sealing valve 415 is movable in the movable direction D1, the first opening 413, which is sealed by the first sealing valve 415, opens, and the internal space R21 is opened to the outside of the air intake side. When the first opening 413 is open, the air W supplied to the drive mechanism receiving part 114 passes through the connecting part 210 and flows from the first opening 413 into the internal space R21.

[0203] The air W flowing into the interior space R21 mixes with the odor components contained in the odor component retainer 130 within the interior space R21 to create a mixed odor-containing air W.

[0204] When the first shut-off valve 415 is movable in the movable direction D1, the connecting portions CL and CR at the ends of the two first support pillars 417 connected to the front of the first shut-off valve 415 are respectively movable along the support pillar actuation guide rail 419 in movable directions D2 and D3, which are orthogonal to the movable direction D1. That is, the first support pillar 417 is movable in the direction where the angle between the first support pillar 417 and the support pillar actuation guide rail 419 decreases.

[0205] When the connecting parts CL and CR are movable in the movable directions D2 and D3 respectively, the ends of the two second support pillars 418 installed on the connecting parts CL and CR are also movable in the movable directions D2 and D3 respectively. That is, the second support pillars 418 are movable in the direction where the angle between the second support pillar 418 and the support pillar moving guide rail 419 decreases.

[0206] Therefore, the second sealing valve 416, which is connected to one end of the two second pillars 418, moves in the rearward movable direction D4. At this time, the first spring 420 is pressed and contracted from the first opening 413 and the second opening 414 toward the pillar actuation guide 419 of the center of the first housing 411.

[0207] When the second sealing valve 416 is movable in the rearward movable direction D4, the second opening 414, which is sealed by the second sealing valve 416, opens, and the internal space R21 is opened to the outside of the exhaust side. When the second opening 414 is open, the odor-containing air W, which is mixed with odor components in the internal space R21, flows from the second opening 414 into the nozzle 103.

[0208] Then, the odorous air W flowing in from the second opening 414 is released to the user outside through the nozzle 103.

[0209] After the odorous air W is released to the outside, if the power to the actuator is cut off, the shape memory alloy SMA, which is in a non-energized state, is released from its contracted state. Under the restoring force of the contracted first spring 420, the first shaft 412 is pushed to its initial position, thereby returning the pusher 141 to its normal initial position. In addition, the first sealing valve 415 and the second sealing valve 416 are movable in the movable direction D4 and movable direction D1 respectively by means of the restoring force of the first spring 420, until they come into contact with the first opening 413 and the first opening 231 and are sealed.

[0210] The odor supply device 400 with housing 401 according to this embodiment can have the same effect as the odor supply device 100 according to the first embodiment. Furthermore, according to the odor supply device 400, the odor supply device 400 can be made thinner, and a structure that is effective for mounting XR / VR devices can be made.

[0211] 5. Examples of applications of odor-providing devices

[0212] As an example of the application of the odor providing device 100, see below Figure 15 Explain the actions taken when performing an olfactory examination or olfactory training.

[0213] First, examiners such as doctors, nurses, and examination technicians use information processing devices to display the examination sequence to the examinee (S1). Here, the information processing device, storage unit (described later), etc., can be installed within the odor supply device 100, or an external device connected via a wired or wireless network can be used. Furthermore, various devices with user interface sections can be installed not only on the examiner's side but also on the examinee's side. Next, the examiner determines the odor (olfactory element) to be released to the examinee and instructs the odor supply device 100 via the information processing device. At this time, the odor supply device 100, having received the instruction, releases the odor from the box 10 containing the specific odor (S3).

[0214] Next, after the odor release ends (S4), the information processing device receives a response from the person being inspected, and the storage unit stores the response (S5). Then, the inspector determines whether to proceed with the next inspection (S6). If yes, the process returns to step S2 to determine the next odor. If no, the inspection ends directly.
