[0011] 1. First embodiment (odor generating cartridge 1)

[0012] (1) Configuration Example of Odor Generating Cartridge 1 According to the First Embodiment

[0013] 1 is a cross-sectional view showing a first embodiment of an odor generating cartridge 1. In this embodiment, the odor generating cartridge 1 includes at least an odor retaining section 11 that retains an odor, an air vent section 12 that takes in air, a flow section 13 that communicates with the air vent section 12 and has one spiral flow path 131, and a discharge section 14 that communicates with the flow section 13 and discharges odor-containing air.

[0014] Furthermore, as necessary, an information display unit, a pump linear motion mechanism 6 and other mechanisms, a deodorizing mechanism 51, a discharge control mechanism 52, etc. may be provided. The pump linear motion mechanism 6 and other mechanisms, the deodorizing mechanism 51, and the discharge control mechanism 52 will be described later in "7. Pump linear motion mechanism 6 and other mechanisms", "8. Deodorizing mechanism 51", and "9. Discharge control mechanism 52", respectively.

[0015] The material for forming the housing 10 of the odor generating cartridge 1 is not particularly limited, and may be, for example, metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; resins such as polyvinyl chloride, polyethylene, phenolic resin, olefin resin, acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, polyimide resin; pottery; porcelain; ceramics; or one or more of these may be freely combined.

[0016] 1, the shape of the odor generating cartridge 1 is not particularly limited as long as there is space inside to store at least the odor retention section 11 and the flow section 13, and the shape may be a substantially cylindrical shape, a substantially elliptical cylindrical shape, a substantially triangular cylindrical shape, a substantially square cylindrical shape, or other substantially polygonal cylindrical shape (including those with rounded corners), a substantially conical shape, a substantially polygonal pyramid shape with a cross section of a substantially triangular or substantially square shape (including those with rounded corners), or a shape that is a free combination of one or more of these shapes. Also, for example, the shape may be a combination of substantially cylindrical shapes with different diameters. Each part of the odor generating cartridge 1 according to this embodiment will be described below.

[0017] (2) Odor retention unit 11

[0018] The odor retention section 11 is a portion that retains odors. The term "odor" as used herein includes any component that stimulates some or all of the receptors present in the nasal cavity, such as odor molecules. In addition to olfactory receptors, the nasal cavity also contains trigeminal receptors that control stimuli such as cold, hot, and painful, and the term "odor" as used herein is a broad concept that includes any component that stimulates some or all of these receptors. Specifically, for example, when menthol is used as an odor, menthol can stimulate via olfactory receptors and can also stimulate a cold sensation via trigeminal receptors (TRPA1 channel), and is therefore included in the term "odor" as used herein.

[0019] There are no particular limitations on the odor retention section 11 as long as it can retain an odor, but for example, it can be an impregnated material impregnated with a component that can generate an odor.

[0020] The material forming the impregnating material may be, for example, an organic polymer material so that the odor can easily penetrate. As the organic polymer material, for example, polyvinyl chloride, polyethylene, phenolic resin, olefin resin, nylon, polyester, synthetic rubber, silicon resin, natural rubber, protein, nucleic acid, lipid, polysaccharide, etc., or a material obtained by freely combining one or more of these, can be used. In addition, polymer resins such as acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, polyimide resin, etc.; metals such as stainless steel and aluminum; inorganic crystals such as quartz; glass; filter paper, etc., or a freely combined one or more of these can be used.

[0021] The impregnating material may be formed to be porous, and examples of the material that can be used include mesh structures, cork, mesoporous silica, calcium carbonate, etc. Furthermore, the impregnating material may be formed to have a fibrous structure or a layered structure (e.g., clay minerals, etc.).

[0022] The form of the impregnating material is not particularly limited, and may be, for example, a sheet, a mesh, a strip (including a dense body thereof), a particle (including a dense body thereof), a gel, a liquid (including a liquid maintained by the surface tension of a carrier or the like), a foam, a three-dimensional structure (for example, a pinholder, a spiral, a spring, etc.), a string (including a dense body thereof), or a freely combined form of one or more of these.

[0023] In this embodiment, as shown in Fig. 1, the impregnating material is in sheet form, rolled into a cylindrical shape and stored in the cylindrical odor-generating cartridge 1. By forming the impregnating material in sheet form, it becomes easier to store it in the cylindrical odor-generating cartridge 1, improving production efficiency. Note that, although the sheet-like impregnating material in Fig. 1 has a single-layer structure, it is also possible to stack multiple layers and store them in the odor-generating cartridge 1 as necessary.

[0024] The odor retained in the impregnating material is not particularly limited as long as it is a component capable of generating an odor (hereinafter also referred to as "fragrance"). Specifically, liquid fragrance, powder fragrance, etc., either as is or dissolved or dispersed in a suitable solvent, essential oil, essential oil diluted with a suitable solvent, fruit juice, food or drink, or dissolved or dispersed in a suitable solvent, or one or more of these can be freely combined and used. In addition, the impregnating material may retain components other than the component capable of generating an odor, such as a component that exerts a pharmacological effect when inhaled. Furthermore, if necessary, the impregnating material may not retain a component capable of generating an odor, and an odorless wind may be discharged using the mechanism of the odor generating cartridge 1. In this case, the odorless wind can also be used for purposes such as an air curtain.

[0025] (3) Ventilation section 12

[0026] The ventilation section 12 is a section that takes in air. The air is basically the outside air around the odor generating cartridge 1, but it may be air collected from a specific location, air containing a specific substance, or the like.

[0027] There are various methods for taking in air into the ventilation section 12. For example, air can be taken in by linearly moving a component such as a pump that abuts against a part of the flow section 13 through the ventilation section 12.

[0028] The pump and other components, the movable source of the components, etc. may be integrated with the odor generating cartridge 1 (may be formed in the same housing), or may be formed separately and used in combination with the odor generating cartridge 1 before linear movement. The odor generating cartridge 1 integrated with the pump and other components, the movable source of the components, etc. may be distributed, or the pump and other components formed separately, the movable source of the components, etc. may be distributed alone.

[0029] The mechanism by which a part of the odor generating cartridge 1 is opened and closed by a member such as a pump will be described later in "7. Pump direct acting mechanism 6 and other mechanisms."

[0030] (4) Flow section 13

[0031] The flow passage 13 is a portion that communicates with the ventilation portion 12 and has at least one or more spiral flow passages 131. By providing the spiral flow passage 131, it is possible to improve manufacturability by utilizing rolling, which is a method for manufacturing screws and the like. In addition, since the flow passage 13 can be metallized, it can be formed of a material that is highly resistant to chemicals and / or has low gas permeability. Furthermore, in the flow passage 13, the area through which the odor-containing air flows has a simple structure, so that little odor remains. Examples of metals include stainless steel (SUS (Steel Use Stainless)) and aluminum, but the present technology is not particularly limited to these.

[0032] In this embodiment, it is preferable that a part or all of the odor retention section 11 abuts against the spiral flow path 131. This increases the contact area between the air flowing through the spiral flow path 131 and the odor retention section 11, thereby efficiently imparting an odor to the air. In addition, since it is possible to generate odor-containing air even in a relatively short spiral flow path 131, the overall dimensions of the odor generating cartridge 1 can be reduced.

[0033] In order to prevent odor leakage, the flow passage section 13 may be provided with a flow passage spring 132 for returning the moved flow passage section 13 to its original position after air flows in through the ventilation section 12, as shown in FIG. 1.

[0034] (5)Discharge part 14

[0035] The outlet portion 14 is a portion that communicates with the flow portion 13 and outlets the odor-containing air. Note that the term "outside" as used herein also includes the concept of a specific space, a specific place, and the like.

[0036] In this embodiment, the discharge part 14 is provided with a discharge part cover 141 and a discharge part spring 142 as shown in FIG. 1 to prevent odor leakage. By opening the discharge part cover 141, odor-containing air is discharged outside the odor generating cartridge 1. That is, the discharge part 14 is moved by the linear motion of a member such as a pump that abuts against a part of the flow part 13, and after air flows in through the ventilation part 12, the air flows through the flow part 13 and comes into contact with the odor retention part 11 to form odor-containing air, and the odor-containing air is discharged to the outside through the discharge part 14 from the discharge part cover 141 that is opened by the linear motion of the member such as the pump. Thereafter, the flow part 13 and the discharge part cover 141 return to their original positions due to the restoring forces of the flow part spring 132 and the discharge part spring 142, and the discharge part cover 141 and the ventilation part 12 are closed.

[0037] (6) Information display section

[0038] The odor generating cartridge 1 according to this embodiment may further include an information display unit. Although the information display unit is not an essential component of the present technology, it is provided on a part of the outer circumferential surface of the odor generating cartridge 1 and is a portion from which information about the odor generating cartridge 1 can be obtained. By including the information display unit, information related to the odor generating cartridge 1 can be obtained, which leads to improved usability.

[0039] The information display unit is not particularly limited, and may be, for example, a pattern image such as a one-dimensional code or a two-dimensional code; a marker or LED light formed in one or more colors, or one or more of these in combination. The information display unit may be read by, for example, a camera or a barcode reader, or may be visually determined by a human being.

[0040] Examples of information held by the information display unit include the type of odor in the odor-generating cartridge 1, the amount of odor remaining, the names of the components that can generate the odor and allergen information for those components, the expiration date and number of uses of the odor-generating cartridge 1, the date and place of manufacture of the odor-generating cartridge 1, and version (Ver.) information, but the present technology is not particularly limited to this information.

[0041] In addition, when a part of the outer peripheral surface has a curvature, it is preferable that the information display part is printed or attached to the part of the outer peripheral surface to an extent that it can be read by the above-mentioned camera, barcode, etc. In this case, the information display part which is a pattern image may be printed on the part of the outer peripheral surface by projection.

[0042] Furthermore, the information display unit may be linked to an application, and the information acquired via the application may be displayed on a screen of a smartphone, a wearable device, a tablet device, a computer, a game machine, etc. In this case, by utilizing the application, a user may add additional information to the acquired information, such as whether or not the odor is pleasant, and the additional information acquired from one or more users may be accumulated on a server or cloud and utilized for machine learning, etc.

[0043] Markers and LED lights formed in one or more colors may be used simply for design purposes.

[0044] (7)Other

[0045] The amount of odor retaining section 11 that it retains can be changed as necessary. That is, there may be multiple odor retaining sections 11 depending on the amount of odor. The capacity of odor retaining section 11 can be achieved, for example, by adjusting the dimensions of odor generating cartridge 1, or by changing the type or volume of the impregnating material that forms odor retaining section 11. Naturally, each odor generating cartridge 1 may be provided with an odor retaining section 11 that retains a different amount or type of odor.

[0046] In addition, the odor generating cartridge 1 can be a replaceable disposable type, thereby improving usability.

[0047] Furthermore, the odor generating cartridge 1 can be stored, for example, sealed in a sealed container until use begins (preferably immediately before use), to prevent deterioration of the components capable of generating an odor. In this case, it is preferable that the container part of the sealed container and the lid part for the sealed container are partly or entirely (preferably entirely) made of a material with high drug resistance and / or low gas permeability. Examples of materials with high drug resistance and / or low gas permeability include metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; resins such as PTFE (polytetrafluoroethylene) and ETFE (Ethylene Tetra Fluoro Ethylen); glass, etc.

[0048] Fig. 2 is a cross-sectional view showing the odor generating cartridge 1 during the manufacturing process of the embodiment shown in Fig. 1. No fragrance has yet been injected into the odor generating cartridge 1 at the manufacturing stage shown in Fig. 2. In other words, there is no need to worry about the fragrance until the odor generating cartridge 1 at the manufacturing stage shown in Fig. 2 is manufactured, and a manufacturing method such as welding by heat can be used. Also, in the odor generating cartridge 1 at the manufacturing stage shown in Fig. 2, when the various components constituting the cartridge 1 are assembled to a certain extent, the fragrance can be gradually injected automatically into the odor retention section 11 by utilizing the reservoir portion formed at the top of the flow section 13 (see the arrow in Fig. 2).

[0049] 2. Second embodiment (odor generating cartridge 1)

[0050] (1) Configuration Example of Odor Generating Cartridge 1 According to the Second Embodiment

[0051] 3 is a cross-sectional view showing a second embodiment of the odor generating cartridge 1. This embodiment is also an embodiment in which an odor can be discharged by air pressure alone. In this embodiment, the odor generating cartridge 1 includes at least an odor retaining section 11 that retains an odor, an air vent section 12 that takes in air, a flow section 13 that communicates with the air vent section 12 and has one spiral flow path 131, a discharge section 14 that communicates with the flow section 13 and discharges odor-containing air, and an air pressure generating section 15. In addition, as necessary, an auxiliary air flow section 16, an information display section, a deodorizing mechanism 51, a discharge control mechanism 52, etc. may be provided. The deodorizing mechanism 51 and the discharge control mechanism 52 will be described later in "8. Deodorizing mechanism 51" and "9. Discharge control mechanism 52", respectively.

[0052] Hereinafter, each part of the odor generating cartridge 1 according to this embodiment will be described. Note that the odor retention section 11, the ejection section 14, and the information display section are the same as those in the first embodiment described above, and therefore description thereof will be omitted here.

[0053] (2) Ventilation section 12 and air pressure generating section 15

[0054] In this embodiment, in order to prevent odor leakage, the ventilation part 12 includes a ventilation part cover 121 and a ventilation part spring 122 as shown in Fig. 3. Therefore, in this embodiment, by opening the ventilation part cover 121, outside air is introduced into the odor generating cartridge 1. After the outside air is introduced, the ventilation part cover 121 returns to its original position due to the restoring force of the ventilation part spring 122.

[0055] In this embodiment, the area through which the odor-containing air passes has a simpler structure than conventional structures, which has the advantage of leaving less odor behind.

[0056] Although the air pressure generating unit 15 is not an essential component of the present technology, in this embodiment, the odor generating cartridge 1 further includes an air pressure generating unit 15 that communicates with the ventilation unit 12. By using the air pressure generating unit 15, it is possible to pressurize outside air, and send the compressed outside air into the ventilation unit 12 using the pressure as an energy source, and open the ventilation unit cover 121 and the discharge unit cover 141 using only air pressure. Therefore, in this embodiment, when odor-containing air is discharged from the discharge unit 14, the entire odor generating cartridge 1 moves toward the right side in FIG. 3.

[0057] The material for forming the air pressure generating unit 15 is not particularly limited, but is preferably flexible. Specifically, for example, polyvinyl chloride, polyethylene, phenol resin, olefin resin, nylon, polyester, synthetic rubber, silicone resin, natural rubber, acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, polyimide resin, etc., or any combination of one or more of these may be used.

[0058] The structure of the air pressure generating unit 15 is not particularly limited as long as it can generate air pressure, and a syringe structure or the like can be adopted. However, in this embodiment, it is preferable to use a spring structure as shown in FIG. 3, etc.

[0059] (3) Auxiliary ventilation section 16

[0060] Fig. 4 is a perspective view showing the odor generating cartridge 1 of the embodiment shown in Fig. 3 equipped with an auxiliary air flow section 16. Fig. 5 is a front view of the odor generating cartridge 1 shown in Fig. 4, Fig. 6 is a rear view of the odor generating cartridge 1 shown in Fig. 4, Fig. 7 is a left side view of the odor generating cartridge 1 shown in Fig. 4, Fig. 8 is a right side view of the odor generating cartridge 1 shown in Fig. 4, Fig. 9 is a plan view of the odor generating cartridge 1 shown in Fig. 4, and Fig. 10 is a bottom view of the odor generating cartridge 1 shown in Fig. 4. Furthermore, Fig. 11 is a perspective cross-sectional view of the odor generating cartridge 1 shown in Fig. 4.

[0061] The auxiliary air flow section 16 is not an essential component of the present technology, but is provided outside the flow section 13 and is a section through which the auxiliary air flows. By providing the auxiliary air flow section 16, the air outside the flow section 13 and flowing through the housing 10 can be used as the auxiliary air when discharging the odor-containing air (see the arrow in FIG. 11).

[0062] The auxiliary air flow section 16 may be detachable from the odor generating cartridge 1. This allows the auxiliary air flow section 16 to be freely detachable depending on space, necessity, and the like. In this case, it is preferable that the odor generating cartridge 1 and the auxiliary air flow section 16 have an engagement mechanism that allows them to be set with one touch. The engagement mechanism is not particularly limited, and examples thereof include engagement using a concave-convex shape; engagement using a claw, pin, hook, clamp, or the like; engagement using an adhesive having adhesiveness to the extent that it can be detached; and slide engagement, but is not particularly limited in the present technology.

[0063] In addition, in this technology, the odor generating cartridge 1 equipped with the auxiliary air flow section 16 may be distributed, or the auxiliary air flow section 16 itself may be distributed alone. Also, it is possible to remove only the auxiliary air flow section 16 and reuse it. This improves usability, and also takes into consideration the global environment, since some parts can be reused.

[0064] In addition, it is preferable that a part or the whole of the auxiliary air passage section 16 is formed on the upper surface side of the surface on which the discharge section 14 is present, as shown in Figures 4 and 5. Figure 16 is a conceptual diagram showing how the odor-containing air mixes with the auxiliary air. As shown in Figure 16, by forming the auxiliary air passage section 16 on the upper surface side of the surface on which the discharge section 14 is present, the auxiliary air and the odor-containing air can be efficiently mixed together, and the odor-containing air can be delivered to the user.

[0065] As shown in FIG. 16, a spring structure or the like may be provided between the discharge portion 14 and the auxiliary air passage portion 16 so long as it does not interfere with the discharge of odor-containing air from the discharge portion 14.

[0066] In this embodiment, a part of the auxiliary air passage 16 is formed on the upper surface side of the surface on which the discharge section 14 is present, and in this case, the auxiliary air passage 16 may include one or more auxiliary air discharge sections 161 that discharge auxiliary air, as shown in Fig. 10. Also, as shown in Fig. 10, a plurality of auxiliary air discharge sections 161 may be formed so as to form parts of concentric circles. In this case, the odor-containing air discharged from the discharge section 14 may be discharged from the center side of the concentric circles.

[0067] As in this embodiment, the auxiliary air flow section 16 may be formed so as to continue from the upper surface side of the surface on which the discharge section 14 is present, and to cover a part or all of the longitudinal direction of the housing 10 of the odor generating cartridge 1. By forming the auxiliary air flow section 16 in such a shape, the odor generating cartridge 1 and the auxiliary air flow section 16 can be easily set with a single touch.

[0068] (4) Modifications of the odor generating cartridge 1 according to the second embodiment

[0069] Fig. 12 is a perspective cross-sectional view showing a modified example of the odor generating cartridge 1 according to the second embodiment. In this modified example, the flow section 13 has two spiral flow paths 131. In this case, as shown in Fig. 12, it is preferable that the odor retention section 11 is provided between the two spiral flow paths 131. In other words, the spiral flow paths 131 are present on the inside and outside of the odor retention section 11. This can further increase the contact area between the air flowing through the spiral flow path 131 and the odor retention section 11, thereby more efficiently imparting odor to the air.

[0070] (5)Other

[0071] In this embodiment, as shown in Fig. 13, an air blowing source 90 may be provided on the air pressure generating unit 15 side of the odor generating cartridge 1. By providing the air blowing source 90, a large amount of auxiliary air can be generated (see the arrow in Fig. 13), and the odor-containing air can be delivered further.

[0072] Examples of the air blowing source 90 include an axial fan, a blower fan, a centrifugal fan, etc. The air blowing source 90 may also be a combination of a diaphragm pump, particularly a diaphragm pump using a piezoelectric element or a motor (e.g., a microblower, etc.), and an airflow expansion mechanism.

[0073] Incidentally, when the air blowing source 90 is provided, there is a problem that noise may be generated depending on the type of the air blowing source 90, the number of the air blowing sources 90 attached, etc. This problem can be solved, for example, by applying a physical stimulus and / or a chemical stimulus to the liquid, vaporizing it to inflate a balloon and generate gas.

[0074] Specifically, as shown in Fig. 14, a thermal stimulus is applied to the liquid in the balloon using a heater, thermistor, Peltier element, etc., and the liquid is vaporized to generate gas, and the balloon is inflated to generate and discharge air, making it possible to provide a silent air source. In addition, when the temperature inside the balloon becomes high, the balloon is maintained in an inflated state, so there is no concern that an odor will continue to be emitted. Therefore, for example, it is possible to prevent an odor from continuing to be emitted in a closed space such as the inside of a vehicle.

[0075] The liquid in the balloon is preferably a liquid that easily expands due to heat. Specifically, for example, alcohol such as methanol or ethanol can be used, but the present embodiment is not limited to these. In addition, the balloon may be provided with a check valve as shown in FIG. 14.

[0076] As another solution, for example, as shown in Fig. 15, pressure can be stored in a balloon with a relatively low operating voltage and released when air is to be discharged, making it possible to provide a low-noise air source. Note that Fig. 15A is a schematic diagram showing an example of an embodiment of air source 90 from the front, and Fig. 15B is a schematic diagram showing the back side of Fig. 15A. Based on a similar principle, low noise can also be achieved by using a syringe action by a linear actuator. Also, the balloon in Fig. 15B may be provided with a check valve (not shown).

[0077] In addition, for example, a silent air source can be created by instantly vaporizing a liquid by using an electric discharge (e.g., spark discharge, direct current arc discharge, glow discharge, etc.) inside a metal piston and instantly expelling air.

[0078] Figure 17 is a conceptual diagram showing a modified example of the opening of the odor generating cartridge 1. Figure 17B shows an enlarged view of a portion of Figure 17A. Note that in Figures 17A and B, the arrows indicate the direction in which the odor-containing air is discharged.

[0079] In the modified example shown in FIG. 17, the odor generating cartridge 1 is structured to open in the pulling direction. Specifically, the outermost part of the odor generating cartridge 1 in the ejection direction is opened by pulling the outermost member 1002 in the ejection direction of the odor generating cartridge 1 using a pulling member 1001 engaged with the outermost member 1002 and the outermost member 1003 on the opposite side to the ejection direction. By adopting this structure, only the ventilation path for the odor-containing air remains, and the amount of odor remaining is extremely small. In addition, after loading the fragrance into the odor generating cartridge 1, there is no need to use another member or the like to hold it down to prevent odor leakage. This allows costs to be reduced.

[0080] In the modified example shown in FIG. 17, a structure is shown in which the odor generating cartridge 1 opens in the pulling direction, but a structure in which the odor generating cartridge 1 opens in the pressing direction may also be adopted.

[0081] 3. Third embodiment (odor generating cartridge 1)

[0082] 18 is a perspective cross-sectional view showing a third embodiment of the odor generating cartridge 1. In this embodiment, the odor generating cartridge 1 at least comprises an odor retaining section 11 that retains an odor, an air vent section 12 that takes in air, a flow section 13 that communicates with the air vent section 12 and has one spiral flow path 131, and a discharge section 14 that communicates with the flow section 13 and discharges odor-containing air. Furthermore, as necessary, an information display unit, a pump linear motion mechanism 6 and other mechanisms, a deodorizing mechanism 51, a discharge control mechanism 52, etc. may be provided. The pump linear motion mechanism 6 and other mechanisms, the deodorizing mechanism 51, and the discharge control mechanism 52 will be described later in "7. Pump linear motion mechanism 6 and other mechanisms", "8. Deodorizing mechanism 51", and "9. Discharge control mechanism 52", respectively.

[0083] Hereinafter, each part of the odor generating cartridge 1 according to this embodiment will be described. Note that the odor retention section 11, the ventilation section 12, and the flow section 13 are the same as those in the first embodiment described above, so the description thereof will be omitted here.

[0084] The odor-generating cartridge 1 shown in this embodiment is designed to eject odor-containing air by moving the entire cartridge 1 in the direction of ejection of the odor-containing air (i.e., forward of the cartridge 1). The arrow in Fig. 18 indicates the pressing direction of the odor-generating cartridge 1. In this case, the periphery of the ejection part 14 may be formed from a separate member, and a protrusion 140 may be provided so that the housing 10 of the cartridge 1 does not directly come into contact with an obstacle such as a wall in front of the odor-generating cartridge 1. The pressing operation may be performed by a member such as a pump, a movable source for the member, or the like.

[0085] 4. Fourth embodiment (odor generating cartridge 1)

[0086] 19 is a perspective cross-sectional view showing a fourth embodiment of the odor generating cartridge 1. In this embodiment, the odor generating cartridge 1 at least comprises an odor retaining section 11 that retains an odor, an air vent section 12 that takes in air, a flow section 13 that communicates with the air vent section 12 and has one spiral flow path 131, and a discharge section 14 that communicates with the flow section 13 and discharges odor-containing air.

[0087] Furthermore, as necessary, an information display unit, a pump linear motion mechanism 6 and other mechanisms, a deodorizing mechanism 51, a discharge control mechanism 52, etc. may be provided. The pump linear motion mechanism 6 and other mechanisms, the deodorizing mechanism 51, and the discharge control mechanism 52 will be described later in "7. Pump linear motion mechanism 6 and other mechanisms", "8. Deodorizing mechanism 51", and "9. Discharge control mechanism 52", respectively.

[0088] Hereinafter, each part of the odor generating cartridge 1 according to this embodiment will be described. Note that since the odor retention section 11 and the ventilation section 12 are the same as those in the first embodiment described above, a description thereof will be omitted here.

[0089] The odor generating cartridge 1 shown in this embodiment is designed to generate odor-containing air by moving the cartridge 1 in the opposite direction to the direction of odor-containing air discharge (i.e., rearward of the cartridge 1). The white arrow in FIG. 19 indicates the pressing direction of the odor generating cartridge 1. In this case, the periphery of the discharge part 14 may be formed with a separate member, and the air outside the flow part 13 may be used as auxiliary wind (see the black arrow in FIG. 19), and an air duct hole 143 may be formed in the separate member. In addition, in this embodiment, since a large amount of space can be created in the odor generating cartridge 1, it is possible to increase the amount of fragrance compared to other cartridges 1. Note that the odor generating cartridge 1 shown in this embodiment may be provided with a shaft 130 to push open the discharge part cover part 141 as necessary. Note that the pressing operation may be performed by a member such as a pump, a movable source of the member, or the like.

[0090] 5. Fifth embodiment (odor generating cartridge 1)

[0091] 20 is a cross-sectional view showing a fifth embodiment of the odor generating cartridge 1. In this embodiment, the odor generating cartridge 1 at least comprises an odor retaining section 11 that retains an odor, an air vent section 12 that takes in air, a flow section 13 that communicates with the air vent section 12 and has two spiral flow paths 131, and a discharge section 14 that communicates with the flow section 13 and discharges odor-containing air.

[0092] Furthermore, as necessary, an information display unit, a pump linear motion mechanism 6 and other mechanisms, a deodorizing mechanism 51, a discharge control mechanism 52, etc. may be provided. The pump linear motion mechanism 6 and other mechanisms, the deodorizing mechanism 51, and the discharge control mechanism 52 will be described later in "7. Pump linear motion mechanism 6 and other mechanisms", "8. Deodorizing mechanism 51", and "9. Discharge control mechanism 52", respectively.

[0093] Hereinafter, each part of the odor generating cartridge 1 according to this embodiment will be described. Note that since the odor retention section 11 and the ventilation section 12 are the same as those in the first embodiment described above, a description thereof will be omitted here.

[0094] The odor generating cartridge 1 shown in this embodiment is configured to generate odor-containing air by pressing the ventilation part 12 side of the cartridge 1 so as to abut against a part of the ventilation part lid 121. The white arrow in FIG. 20 indicates the pressing direction of the ventilation part lid 121. In this case, the ventilation part lid 121 pressed through the ventilation part 12 opens the discharge part lid 141 through the shaft 130. As a result, the air flowing in from the ventilation part 12 is scented by passing through the flow part 13, and the odor-containing air is discharged from the discharge part 14. After the odor-containing air is discharged, the discharge part lid 141 and the ventilation part lid 121 return to their original positions due to the restoring forces of the discharge part spring 142 and the ventilation part spring 122. In this embodiment, two spiral flow paths 131 are provided, and it is possible to efficiently scent the air flowing in from the ventilation part 12.

[0095] In this embodiment, the periphery of the discharge part 14 is formed from a separate member, thereby saving space on the member on the discharge part 14 side of the housing 10. This makes it possible to generate odor-containing air efficiently even in a limited space. The pressing operation may be performed by a member such as a pump, a movable source for the member, or the like.

[0096] 6. Sixth embodiment (odor generating cartridge 1)

[0097] 21 is a perspective cross-sectional view showing a sixth embodiment of the odor generating cartridge 1. In this embodiment, the odor generating cartridge 1 at least comprises an odor retaining section 11 that retains an odor, an air vent section 12 that takes in air, a flow section 13 that communicates with the air vent section 12 and has one spiral flow path 131, and a discharge section 14 that communicates with the flow section 13 and discharges odor-containing air.

[0098] Furthermore, as necessary, an information display unit, a deodorizing mechanism 51, a discharge control mechanism 52, etc. may be provided. The deodorizing mechanism 51 and the discharge control mechanism 52 will be described later in "8. Deodorizing mechanism 51" and "9. Discharge control mechanism 52", respectively.

[0099] Hereinafter, each part of the odor generating cartridge 1 according to this embodiment will be described. Note that the ventilation section 12 and the discharge section 14 are the same as those in the first embodiment described above, and therefore the description thereof will be omitted here.

[0100] The odor generating cartridge 1 shown in this embodiment is designed to generate odor-containing air by sliding internal parts (see the part surrounded by a thick line in FIG. 21) against the housing 10 of the cartridge 1. The "internal parts" here include at least the odor retention section 11 and the flow section 13, but in this embodiment, it is preferable that all of the internal parts (see the part surrounded by a thick line in FIG. 21) slide. The white arrow in FIG. 21 indicates the sliding direction. In this case, if the odor retention section 11 hits the housing 10 during sliding, resistance is high and size accuracy is low, so it is preferable to form a cover member 111 to cover this. Furthermore, when sliding, the flow section 13 may be provided with a flow section spring 132.

[0101] The odor generating cartridge 1 shown in this embodiment slides, so there is space and air can easily pass through, making it possible to mix and release the odor. The method for mixing the odor is not particularly limited, and a spring structure, a stent, a vertical slit, or a combination of one or more of these can be used.

[0102] 7. Pump direct drive mechanism 6 and other mechanisms

[0103] (1) Configuration example of pump linear motion mechanism 6

[0104] 22 is an explanatory diagram for explaining the pump direct-acting mechanism 6. By using the pump direct-acting mechanism 6, as described above, it is possible to directly move the pump section 61 with respect to the odor generating cartridge 1, and to press one or more selected from the group consisting of a part of the flow section 13, the vent section cover section 121, the discharge section cover section 141, and a member (valve) 64 provided between the pump section 61 and the cartridge 1, thereby opening and closing them. Conventionally, the pump section was fixed and a separate member, a plunger, was moved, but in contrast, in the present technology, air flows efficiently and there is no need to separately prepare members such as a plunger, so that a smaller number of parts are required and a compact opening and closing mechanism can be provided.

[0105] The pump linear motion mechanism 6 includes at least a pump section 61, a sealing section 62, and a linear motion source 63. Other parts may be included as necessary. As shown in FIG. 22, the pump section 61 moves in a linear motion direction in part or in whole by the movement of the linear motion source 63, and presses one or more selected from the group consisting of a part of the flow section 13, the vent section cover 121, the discharge section cover 141, and a member 64 provided between the pump section 61 and the cartridge 1, to open and close them. After the odor generating cartridge 1 is opened by the movement of the pump section 61, the odor generating cartridge 1 is sealed by a sealing section 62 formed so as to contact a necessary place such as the outer circumferential surface of the member 64, as shown in FIG. 22, in order to prevent the intrusion of excess outside air, dust, etc.

[0106] The material for forming the pump portion 61 and the sealing portion 62 is not particularly limited, but is preferably flexible. Specifically, for example, polyvinyl chloride, polyethylene, phenolic resin, olefin resin, nylon, polyester, synthetic rubber, silicone resin, natural rubber, acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, polyimide resin, etc., or one or more of these may be freely combined and used.

[0107] The shape of the pump portion 61 is not particularly limited, and may be a substantially polygonal prism such as a substantially circular cylinder, a substantially elliptical cylinder, a substantially triangular prism, a substantially square prism, etc. (including those with rounded corners), a substantially cone, a substantially polygonal pyramid with a cross section of a substantially triangle, a substantially square, etc. (including those with rounded corners), or a shape that is a free combination of one or more of these. In addition, for example, a shape that combines substantially cylindrical shapes with different diameters may also be used.

[0108] The linear motion movable source 63 is not particularly limited as long as it can move the pump section 61 in a linear direction, and examples thereof include a shape memory alloy (SMA), a motor, a solenoid, a linear slide type, a pneumatic (air pump type), an actuator equipped with a small electromagnet, etc. Note that, as described above, the "linear motion" mentioned here includes not only the case where one member moves in a linear direction, but also the case where some members of a plurality of connected members move in a linear direction.

[0109] Below, we will explain each embodiment of the pump linear motion mechanism 6. In the following embodiments, the odor generating cartridge 1 uses the odor generating cartridge 1 according to the fifth embodiment described above. The odor generating cartridge 1 is similar to that of the fifth embodiment described above, so a description thereof will be omitted here.

[0110] (1-1) First embodiment of pump linear motion mechanism 6

[0111] Fig. 23 is a perspective view showing a first embodiment of a pump linear motion mechanism 6, and Fig. 24 is a cross-sectional view of the embodiment shown in Fig. 23. The pump linear motion mechanism 6 of the embodiment shown in Fig. 23 and Fig. 24 includes an odor generating cartridge 1, a pump section 61 that abuts against the vent cover section 121 of the cartridge 1, a sealing section 62 (not shown in Fig. 23), and a linear motion source 63 that linearly moves the pump section 61.

[0112] In this embodiment, a DC motor is used as the linearly movable source 63, and the pump section 61 is moved by the movement of the DC motor. Note that in this embodiment, the shape of the pump section 61 is bent at approximately 90° from a portion parallel to the odor generating cartridge 1, and a part of the pump section 61 at the end of the bend abuts against the ventilation section cover section 121 and moves linearly. In this way, in this embodiment, the shape of the pump section 61 can be devised according to the space in which the odor generating cartridge 1 is to be installed. Note that the pump section 61 may be formed into a single block by joining multiple members as shown in this embodiment.

[0113] (1-2) Second embodiment of pump linear motion mechanism 6

[0114] Fig. 25 is a perspective view showing a second embodiment of the pump linear motion mechanism 6, and Fig. 26 is a cross-sectional view of the embodiment shown in Fig. 25. The pump linear motion mechanism 6 of the embodiment shown in Fig. 25 and Fig. 26 includes three odor generating cartridges 1, three pump sections 61 abutting against the vent cover sections 121 of the cartridges 1, a plurality of sealing sections 62 (not shown in Fig. 25), three linear motion movable sources 63 that move the pump sections 61, and three members 64 provided between the pump sections 61 and the cartridges 1.

[0115] In this embodiment, a plurality of each of the odor generating cartridge 1, pump unit 61, sealing unit 62, linearly movable source 63, and member 64 are provided, and this configuration can also be adopted as the pump linear motion mechanism 6 in the present technology. Note that, in the present technology, the type, shape, or number of each part may be the same, or may be partially or entirely different. In this embodiment, the linearly movable source 63 uses a shape memory alloy SMA, and each pump unit 61 is linearly movable for each block by the movement of the shape memory alloy SMA. Note that the pump unit 61 and / or the member 64 provided between the pump unit 61 and the cartridge 1 may include a return spring 611 as necessary, as shown in this embodiment.

[0116] In this embodiment, the movable source holder 631 is provided for holding the linear movable source 63. The movable source holder 631 may hold not only the linear movable source 63 but also the pump unit 61 and the odor generating cartridge 1. If the linear movable source 63 is prone to generating heat, the movable source holder 631 is preferably formed from a heat-resistant material. In this embodiment, the required heat-resistant temperature is preferably 70°C or higher, more preferably 80°C or higher, even more preferably 85°C or higher, and particularly preferably 90°C or higher.

[0117] Specific examples of heat-resistant materials include heat-resistant resin compositions. Examples of heat-resistant resin compositions include polyamide resins such as polycaproamide (nylon 6) and polyhexamethylene adipamide (nylon 66); polyphenylene sulfide resins (PPS resins); and combinations of one or more of these. In addition, these resins may be mixed with reinforcing fibers such as glass fibers, carbon fibers, and aramid fibers at a desired content.

[0118] (1-3) Third embodiment of pump linear motion mechanism 6

[0119] Fig. 27 is a perspective view showing a third embodiment of the pump linear motion mechanism 6. The pump linear motion mechanism 6 of the embodiment shown in Fig. 27 includes an odor generating cartridge 1, a pump section 61 that abuts against the vent cover section 121 of the cartridge 1, a sealing section 62 (not shown), a linear motion source 63 that linearly moves the pump section 61, and a member 64 provided between the pump section 61 and the cartridge 1.

[0120] In this embodiment, a DC motor is used as the linearly movable source 63, and the linear motion of the DC motor causes the pump section 61 to linearly move. The shape of the pump section 61 in this embodiment is different from the shape of the pump section 61 in the pump linear motion mechanism 6 according to the first embodiment. In this manner, in this embodiment, the shape of the pump section 61, the arrangement of the linearly movable source 63, the presence or absence of the member 64, and the like can be devised as necessary.

[0121] (1-4) Fourth embodiment of pump linear motion mechanism 6

[0122] Fig. 28 is a perspective view showing a fourth embodiment of the pump linear motion mechanism 6. The pump linear motion mechanism 6 of the embodiment shown in Fig. 28 includes an odor generating cartridge 1, a pump section 61 that abuts against the vent cover section 121 of the cartridge 1, a sealing section 62 (not shown), a linear motion source 63 that linearly moves the pump section 61, and a member 64 provided between the pump section 61 and the cartridge 1, and has a form in which a part of the pump linear motion mechanism 6 according to the second embodiment described above is extracted.

[0123] In this embodiment, similarly to the second embodiment, a shape memory alloy SMA is used as the linear motion movable source 63, and the shape memory alloy SMA is folded back in multiple places as shown in Fig. 28. In this case, it is preferable that the linear motion movable source 63 further includes an extra length adjustment mechanism 632 for the shape memory alloy SMA. By including the extra length adjustment mechanism 632, it is possible to simplify the extra length adjustment, double the number of folds (double the amount of displacement), etc., and also contribute to the miniaturization of the linear motion movable source 63.

[0124] (1-5) Fifth embodiment of pump linear motion mechanism 6

[0125] Fig. 29 is a perspective view showing a fifth embodiment of a pump linear motion mechanism 6. The pump linear motion mechanism 6 of the embodiment shown in Fig. 29 includes three odor generating cartridges 1, three pump sections 61 abutting against the vent cover sections 121 of the cartridges 1, a plurality of sealing sections 62 (not shown), one linear motion movable source 63 that moves the pump sections 61, and one member 64 provided between the pump sections 61 and the cartridges 1.

[0126] In this embodiment, compared to the second embodiment described above, there is one direct-acting movable source 63. In this embodiment, a camshaft and a motor are used as the direct-acting movable source 63, and when the motor is operated, the camshaft rotates, and each pump section 61 moves directly for each block. As a result, when there is no need to open the odor generating cartridges 1 individually, the number of direct-acting movable sources 63 can be reduced, leading to cost reduction.

[0127] (2) Example 1 of a mechanism other than the pump linear motion mechanism 6 (mechanism 7 using a link structure)

[0128] 30 is a perspective view showing a mechanism 7 using a link structure. In the present technology, any one or more selected from the group consisting of a part of the flow section 13, the vent section cover 121, the discharge section cover 141, and the valve 74 can be opened or closed by a mechanism other than the pump linear motion mechanism 6.

[0129] The link structure in this mechanical example includes a shape memory alloy SMA 71 and links 72 and 73. By operating the shape memory alloy SMA 71, the links 72 and 73 are moved, and for example, a force that pulls the odor generating cartridge 1 in the downward direction shown in Fig. 30 is generated, thereby opening and closing the valve 74. Note that the shape, configuration, pulling direction, etc. of the link structure in this mechanical example are merely examples, and the present technology is not particularly limited as long as the valve 74 can be opened and closed.

[0130] (3) Example 2 of a mechanism other than the pump linear motion mechanism 6 (mechanism 8 using TSA)

[0131] FIG. 31 is a perspective view showing a mechanism 8 using a TSA (twisted string actuator). In addition to the mechanism example 1 described above, the present technology can use the mechanism 8 using a TSA. The TSA at least includes a motor, a rotating member, two strings or wires, and a guide unit for guiding the two strings or wires. The motor rotates the rotating member, and the two strings or wires are twisted with each other. Therefore, the length of the string or wire in the twisted region when the twist occurs is shorter than the length of the string or wire in the twisted region when the twist does not occur. In addition, the length of the string or wire can be further shortened by applying heat to the string or wire as necessary.

[0132] The mechanism 8 in this mechanism example includes at least the above-mentioned TSA 81 and a return spring (compression spring) 82 on the outer periphery of the TSA 81. By driving the motor, two strings or wires that are components of the TSA are twisted to open and close the valve 83. By providing the return spring 82 on the outside of the TSA 81, the overall dimensions of the odor generating cartridge 1 including this mechanism example can be reduced. Note that the configuration etc. in this mechanism example are merely an example, and the present technology is not particularly limited as long as it is possible to open and close the valve 83.

[0133] 8. Deodorizing mechanism 51

[0134] (1) Example of the configuration of the deodorizing mechanism 51

[0135] 32 and 33 are explanatory diagrams for explaining the deodorizing mechanism 51. Note that B of Fig. 32 is a perspective cross-sectional view of the odor generating cartridge 1 shown in A, and B of Fig. 33 is a partially enlarged view of the deodorizing mechanism 51 shown in A. As described above, the odor generating cartridge 1 according to the present technology may further include a deodorizing mechanism 51 as necessary.

[0136] The deodorizing mechanism 51 shown in this embodiment takes deodorizing measures against the suction hole 612 of the pump linear motion mechanism 6 described above. In A of FIG. 32 and A of FIG. 33, the white arrow indicates the discharge direction of the odor-containing air. By taking deodorizing measures against the suction hole 612, the odor of the components such as resin and the surrounding environment can be deodorized before the odor-containing air is generated, and the odor that is originally intended to be presented can be presented. In FIG. 32, the odor generating cartridge 1 is stored in a substantially rectangular cylindrical outer member as shown in B of FIG. 32. In B of FIG. 33, the black arrow indicates the inflow direction of the odor of the components and the surrounding environment, and the gray arrow indicates the flow direction of the outside air after deodorization.

[0137] As shown in B of Fig. 33, the deodorizing mechanism 51 includes a front member 511 and a rear member 512, and the front member 511 and the rear member 512 are fitted together. In addition, as shown in B of Fig. 33, a deodorizing material part 513 and the like are present between the front member 511 and the rear member 512.

[0138] (2) Front member 511

[0139] The material for forming the front member 511 is not particularly limited, and examples thereof include glass; metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; resins such as polycarbonate, polyvinyl chloride, polyethylene, phenolic resin, olefin resin, acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, polyimide resin, and the like; or one or more of these may be freely combined.

[0140] The shape of the front member 511 is not particularly limited as long as it can accommodate the deodorizing material part 513 described later, and can be designed to be, for example, a substantially polygonal shape such as a substantially triangular prism or a substantially square prism, a substantially cylindrical shape, a substantially elliptical cylindrical shape, or the like, or one or more of these shapes can be freely combined. In addition, if the shape is a polygonal shape, the corners may be rounded, or a taper or step may be provided on a part of the front member 511.

[0141] The front member 511 has a deodorizing material section 513 therein, as shown in B of FIG. 33. The deodorizing material section 513 is not particularly limited, and may be, for example, a gas adsorbing substance woven or kneaded into the material, packed in a bag made of a gas-permeable material, or various fibers or structures themselves may have a gas adsorbing structure, or may have a filter structure. The gas adsorbing material may be, for example, activated carbon (for example, palm, fir, bamboo, resin, wood, fiber, coal, etc.), zeolite, layered compounds (for example, sheet silicate, alumina, etc.), porous silica (including mesoporous silica), or one or more of these may be freely combined. The shape of the deodorizing material section 513 is also not particularly limited, and may be, for example, powder, granules, fibers, molded products, sheets (for example, nonwoven fabric, woven fabric, etc.), rods, plates, etc. Furthermore, the surface of the deodorizing material portion 513 may be subjected to, for example, a surface functional group exposure treatment (eg, acidification, alkalinization, polarization, non-polarization, etc.) regardless of whether or not activation treatment has been performed.

[0142] The upper surface and / or lower surface of the deodorizing material part 513 may have one or more fall prevention parts 5131 for preventing the deodorizing material part 513 from falling. The fall prevention part 5131 is not particularly limited as long as it can prevent the deodorizing material part 513 from falling, and may be formed, for example, in a sheet-like shape, a mesh structure, a filter structure, or the like. In addition, by attaching the fall prevention part 5131, it is possible to prevent the pump part 61 from sucking in gas adsorbent substances formed in powder or granular form such as activated carbon. The fall prevention part 5131 can be attached to the deodorizing material part 513 using, for example, an adhesive, and it is preferable that the fall prevention part 5131 is attached so as not to leave any gaps.

[0143] (3) Rear member 512

[0144] The material forming the rear member 512 and the shape of the rear member 512 are not particularly limited, and are similar to the above-mentioned front member 511, so description thereof will be omitted here.

[0145] Furthermore, one or more attachment parts 515 for attaching the deodorizing mechanism 51 to another article, a housing, or the like may be formed on the surface of the rear member 512 itself that is not fitted with the front member 511. In A of Fig. 33, the deodorizing mechanism 51 is attached to another article (in this embodiment, the pump linear motion mechanism 6). The attachment part 515 is not particularly limited as long as it can fix the deodorizing mechanism 51, and can be formed, for example, from a sheet-like adhesive, double-sided tape, or the like.

[0146] The rear member 512 may have an air blowing section therein as necessary. The air blowing section is not particularly limited, and examples thereof include an axial flow fan, a blower fan, and a centrifugal fan. Alternatively, the air blowing section may be a diaphragm pump, particularly a diaphragm pump using a piezoelectric element or a motor (e.g., a microblower). In this case, the rear member 512 preferably has a groove or the like through which a harness or the like that connects the air blowing section to an external driving source is passed so that the air blowing section obtains energy from an external driving source (e.g., a piezoelectric element, a motor, etc.). Furthermore, the lower surface side of the air blowing section may be provided with one or more fixing parts for fixing the air blowing section. The fixing part is not particularly limited as long as it can fix the air blowing section, and may be formed, for example, of a sheet-like adhesive, double-sided tape, or the like.

[0147] (4) Example of Fitting Between Front Member 511 and Rear Member 512

[0148] In the case where the rear member 512 has, for example, a fitting groove (not shown), an adhesive is applied when fitting the front member 511 to the fitting groove, and the front member 511 is inserted into the fitting groove of the rear member 512 to fit the two members together. Furthermore, the adhesive or the like can completely eliminate any gaps, and the gap between the front member 511 and the rear member 512 can be sealed. Note that in this embodiment, the fitting groove is not an essential component, and the gap between the front member 511 and the rear member 512 may be sealed using an O-ring, screw fastening, or the like.

[0149] 9. Discharge control mechanism 52

[0150] (1) Configuration example of discharge control mechanism 52

[0151] 34 and 35 are explanatory diagrams for explaining the discharge control mechanism 52. As described above, the odor generating cartridge 1 according to the present technology may further include a discharge control mechanism 52 for controlling the discharge of odor-containing air, as necessary. In addition, in Figs. 34 and 35, the odor generating cartridge 1 is built into a substantially rectangular tubular housing, and is structured to discharge odor-containing air through a hole 522 communicating with the discharge part 14. In this embodiment, a pump linear motion mechanism 6 is also built into the substantially rectangular tubular housing.

[0152] (2) Directional control unit 521

[0153] The discharge control mechanism 52 according to this embodiment may include a direction control unit 521a for controlling the discharge direction of the odor-containing air, as shown in Fig. 34. The control method in the direction control unit 521a is not particularly limited, but for example, a louver or the like of a passage through which the air discharged from the air blowing source 90 flows is swung up and down to a desired direction, and the air from the air blowing source 90 is discharged. Then, by blowing the air discharged from the air blowing source 90 against the odor-containing air discharged from the discharge portion 14 of the odor generating cartridge 1, the odor-containing air is drawn into the air and pulled, so that the odor-containing air can be delivered in the desired direction.

[0154] Furthermore, the discharge control mechanism 52 according to this embodiment may include a direction control unit 521b that can direct the left-right direction of the air discharged from the air blowing source 90 to a desired direction, as shown in Fig. 35. In Fig. 35, the direction control unit 521b also functions as a passage through which the air discharged from the air blowing source 90 flows. That is, the passage is swung left-right to direct the air from the air blowing source 90 to a desired direction (see A and B in Fig. 35), and the air is discharged from the air blowing source 90. Then, similar to 521a, the odor-containing air can be drawn into the air and pulled, thereby delivering the odor-containing air in a desired direction.

[0155] The emission control mechanism 52 may be composed of either a directional control unit 521a or a directional control unit 521b, but by having both a directional control unit 521a and a directional control unit 521b, the emission direction of odor-containing air can be controlled in the up, down, left, and right directions.

[0156] (3)Other

[0157] In this embodiment, the air blowing source 90 is the same as that described in "(5) Others" of "2. Second embodiment (Odor generating cartridge 1)", and therefore a description thereof will be omitted here. Also, in the above-mentioned embodiment, the control of the ejection direction was described as an ejection condition for the odor-containing air, but in the ejection control mechanism 52, by simultaneously adjusting the air blowing source 90, it is possible to control the type of odor, ejection distance, ejection amount, ejection speed, ejection angle, ejection location, diffusion range, and the like.

[0158] Furthermore, in the emission control mechanism 52, the emission direction of the odor-containing air can be controlled manually or automatically via a wired or wireless (e.g., Wi-Fi, Bluetooth, etc.) network using one or more directional control units 521. Furthermore, when the emission direction of the odor-containing air is controlled automatically, the emission direction may be determined using information acquired by an information acquisition unit (not shown) that acquires information related to a specific target. Note that the information acquisition unit has the same function as the information acquisition unit 501 in "10. Seventh embodiment (odor generation system 500)" described later, and therefore will not be described here.

[0159] 10. Seventh embodiment (odor generation system 500)

[0160] (1) Configuration example of odor generation system 500

[0161] 36 is a block diagram showing an example of an embodiment of an odor generation system 500. In this embodiment, the odor generation system 500 includes at least an information acquisition unit 501, a control unit 502, an odor presentation unit 503, a storage unit 504, an output unit 505, and a blower mechanism 506. In addition, the odor generation system 500 may include other components as necessary. Below, each part of the odor generation system 500 according to the present technology will be described.

[0162] (2) Information acquisition unit 501

[0163] The information acquisition unit 501 is a part that acquires information related to a specific target. The "target" here is a broad concept that includes not only humans but also all kinds of animals and plants, such as dogs, cats, monkeys, rabbits, hamsters, mice, guinea pigs, horses, cows, pigs, chickens, parakeets, parrots, owls, owls, squirrels, flying squirrels, turtles, lizards, snakes, salamanders, other animals, ornamental fish, insects, and plants. Of these, humans and pet animals are particularly preferable as targets.

[0164] In addition, the specific target is not necessarily one individual, but may be a plurality of individuals (groups). The specific target may be either moving or stationary.

[0165] Specific examples of the information acquisition unit 501 include an environmental sensor, a vital sensor, a camera sensor, a brightness sensor, an infrared sensor, an odor sensor, a gas sensor, etc., and these may be used alone or in combination of two or more kinds.

[0166] The information obtained from the various sensors described above is not particularly limited, and for example, the environmental sensor may obtain information such as temperature, humidity, air pressure, and ultraviolet radiation exposure; the vital sensor may obtain information such as vital signs including pulse, blood pressure, respiration, and body temperature, as well as brain pressure, blinking frequency, amount of bleeding, amount of sweat (including amount of sweat during sleep), amount of tears secreted, level of consciousness, and amount of excrement; the camera may obtain information such as race, sex, age, whether or not an object is present, the position of the object, the number of objects, the height of the object, and the position of a specific part of the object (e.g., the face, nose, hands, feet, back, etc.); and the brightness sensor may obtain information such as Brightness sensors measure the amount of indoor lighting, entrance lighting, etc.; infrared sensors measure changes in outside temperature, room temperature, radiant temperature, perceived temperature, human position, and the operating status of various devices (e.g., televisions, air conditioners, electric fans, circulators, air purifiers, humidifiers, commercial air conditioning systems, automatic doors, automatic toilet lids, non-contact thermometers, etc.); odor sensors measure bad odors, odors, etc.; gas sensors measure information on nitrogen, oxygen, carbon monoxide, carbon dioxide, alcohol, fuel vapor gas, etc., or a combination of one or more of these. Only one type of information obtained from various sensors may be used, but by using two or more types of information in combination, it is possible to present an odor that is appropriate to a specific target with greater accuracy.

[0167] The information acquiring unit 501 may be fixed at a desired position by a stand, a clip, a tripod, a hanging mechanism, etc. In addition, these may be formed of a rod, a plate-like member, etc., and may be formed of a shape-memory material, etc.

[0168] (3) Control unit 502

[0169] The control unit 502 is a part that determines the odor presentation conditions based on the information acquired by the information acquisition unit 501 and / or information prepared in advance. Examples of the information acquired by the information acquisition unit 501 include information obtained from the various sensors described above.

[0170] Examples of the information prepared in advance include information input or registered in advance by the user, weather forecast information, traffic congestion forecast information, etc. Examples of the information input or registered in advance by the user include gender, race, preferred odor presentation conditions, height, weight, current mood, current physical condition, average sleep time in a predetermined period (e.g., the past week), average number of bowel movements in a predetermined period, smoking history, drinking history, planned time of falling asleep or waking up, whether or not the user is pregnant or menstruating if the user is female, and the like, or a combination of one or more of these, but the present technology is not particularly limited thereto.

[0171] The "odor" here is the same as that described in "(2) Odor retention unit 11" in "1. First embodiment (Odor generating cartridge 1)", so a description thereof will be omitted here. The odor presentation conditions determined by the control unit 502 include, for example, the type of odor (including the case where one or more types are mixed), the odor discharge distance, the odor discharge amount, the odor strength (including concentration), the odor discharge direction, the odor discharge location, the odor diffusion degree, the odor discharge time, the odor discharge stop time, the number of odor discharges, the odor discharge rhythm, the mixing ratio of each type of odor in the case of a mixture of two or more types, or a combination of one or more of these, but are not particularly limited in the present technology. In addition, when there are multiple odor presentation units 503, the control unit 502 may determine the same odor presentation conditions for each odor presentation unit 503, or may determine the odor presentation conditions for each odor presentation unit 503.

[0172] The control unit 502 may evaluate the state of the specific target after the odor is presented. The "state" here includes not only one or more pieces of information acquired from the information acquisition unit 501, but also information inferred from the acquired one or more pieces of information. Specifically, for example, if the pulse rate decreases after the odor is presented, the target to which the odor is presented may be evaluated as being calm. On the other hand, if the pulse rate increases, the target to which the odor is presented may be evaluated as being excited. Furthermore, in this embodiment, the control unit 502 may perform feedback control regarding the odor presentation conditions based on the results of the evaluation.

[0173] In this case, the control unit 502 can set a desired environment based on the results of the evaluation. The term "setting" here includes both manual and automatic concepts, and also includes manual or automatic up to a certain point and automatic or manual thereafter. Specifically, for example, when it is desired to create a relaxing environment for a specific subject, the control unit 502 can set the desired environment by changing the odor presentation conditions based on the results of the evaluation. Also, when it is desired for the specific subject to create an environment in which he or she wants to concentrate, the control unit 502 can set the desired environment by changing the odor presentation conditions based on the instructions from the specific subject and the results of the evaluation.

[0174] The control unit 502 may have, for example, an internal control unit 5021 that controls the information acquisition unit 501, the odor presentation unit 503, and the blowing mechanism 506, and an external control unit 5022 that can communicate with the internal control unit 5021 via a wired or wireless (e.g., Wi-Fi, Bluetooth, etc.) network. In this case, the odor presentation conditions are determined by the internal control unit 5021 and / or the external control unit 5022, but by using both the internal control unit 5021 and the external control unit 5022 in combination, an odor corresponding to a specific target can be presented with higher accuracy. In addition, the control unit 502 may be able to communicate with each part of the odor generation system 500 via a wired or wireless network.

[0175] Specific examples of the external control unit 5022 include applications stored in a smartphone, a tablet terminal, a wearable terminal, a personal computer, etc., but are not particularly limited in the present technology. Examples of the applications include native applications, Web applications, hybrid applications, and built-in applications. The external control unit 5022 may also include a storage unit 504 and / or an output unit 505, which will be described later. Although not shown, the external control unit 5022 may also include an input unit (user interface) that accepts instructions from a user. When the external control unit 5022 has an input unit, the user may input the previously prepared information via the input unit.

[0176] (4) Odor presentation unit 503

[0177] The odor presentation unit 503 is a part that presents an odor based on the odor presentation conditions determined by the control unit 502. A specific example of the odor presentation unit 503 is one that includes an odor generating cartridge 1.

[0178] FIG. 37 is a perspective view showing an example of an embodiment of the odor presentation unit 503. FIG. 38 is a six-sided view showing the embodiment shown in FIG. 37, where A is a front view, B is a rear view, C is a left side view, D is a right side view, E is a plan view, and F is a bottom view. FIG. 39 is a perspective view showing an example of the structure inside the housing of the embodiment shown in FIG. 37. In this embodiment, the odor presentation unit 503 at least includes an odor generating cartridge 1 and an odor control unit 532. It may also include other parts as necessary. In this embodiment, the odor generating cartridge 1 and the odor control unit 532 are present inside the housing of the odor presentation unit 503, as shown in FIG. 39.

[0179] In this embodiment, the odor presentation unit 503 is substantially rectangular tubular as shown in Fig. 37, but the shape of the odor presentation unit 503 is not particularly limited, and may be substantially polygonal tubular such as substantially cylindrical, substantially elliptical, substantially triangular, or substantially rectangular tubular (including those with rounded corners), substantially conical, or substantially polygonal pyramid with a cross section of substantially triangular, substantially square, or the like (including those with rounded corners), or a freely combined shape of one or more of these. Also, for example, the odor presentation unit 503 may be a shape that combines substantially cylindrical shapes with different diameters.

[0180] The odor presentation unit 503 has an outlet 533 from which an odor is emitted as a result of the odor control unit 532 operating in accordance with the odor presentation conditions instructed by the control unit 502. The outlet 533 may be provided in a part of the housing of the presentation unit 503, for example, at the position indicated by E in FIG.

[0181] In this embodiment, the odor presentation unit 503 may be composed of one or more odor presentation units 503, and when composed of two or more odor presentation units 503, it is also possible to place two or more odor presentation units 503 side by side by a joining mechanism provided on the side of the housing of the odor presentation unit 503, etc. Each part of the odor presentation unit 503 will be described below.

[0182] [Odor generating cartridge 1] The odor generating cartridge 1 is similar to those described in "1. First embodiment (odor generating cartridge 1)" to "6. Sixth embodiment (odor generating cartridge 1)," and therefore description thereof will be omitted here.

[0183] [Modification of odor generating cartridge 1] Modified examples of the odor generating cartridge 1 will now be described. Figure 40 is a six-sided view showing a modified example of odor generating cartridge 1, where A is a front view, B is a rear view, C is a left side view, D is a right side view, E is a plan view, and F is a bottom view. Figure 41 is a perspective view of the embodiment shown in Figure 40, and Figure 42 is a cross-sectional view along line PP of the embodiment shown in Figure 40. Odor generating cartridge 1 of this modified example at least comprises odor retaining section 101, ventilation section 102, and connecting section 103.

[0184] As shown in Fig. 42, the odor retaining section 101 at least comprises an impregnating material 20 and a container section 21. In this embodiment, the lid section 22 corresponding to the container section 21 is joined to a part of a connecting section 103, which will be described later. In this embodiment, the joining also includes a case in which the connecting section 103 and the lid section 22 are formed as a single molded part.

[0185] The material forming the impregnating material 20 and the form of the impregnating material 20 are not particularly limited, and are similar to those described in "1. First embodiment (odor generating cartridge 1)" to "6. Sixth embodiment (odor generating cartridge 1)", so a description thereof will be omitted here. The odor retained in the impregnating material 20 is also not particularly limited, and is similar to those described in "1. First embodiment (odor generating cartridge 1)" to "6. Sixth embodiment (odor generating cartridge 1)", so a description thereof will be omitted here.

[0186] The container part 21 preferably has a two-layer structure, and in this embodiment, as shown in FIG. 42, is composed of an inner layer part 211 forming the inside that holds the impregnating material 20, and an outer layer part 212 forming the outside of the container part 21. The material forming the inner layer part 211 is not particularly limited, but in this embodiment, it is preferable that a part or the whole of the inner layer part 211 is formed of glass or metal. Examples of metals include stainless steel (SUS (Steel Use Stainless)) and aluminum. In this embodiment, the inner wall of the inner layer part 211 on the impregnating material 20 side may be formed of metal foil, or the inner wall may be metal-plated.

[0187] The ventilation section 102 includes an openable / closable ventilation opening 30. In the present embodiment, the ventilation section 102 is configured to be divided into two sections (a first ventilation section 102a and a second ventilation section 102b) by the two ventilation openings 30 as shown in Fig. 42, but this is not particularly limited in the present technology, and the ventilation section 102 may be configured as a single section, or may be configured as being divided into three or more sections.

[0188] In this embodiment, as shown in FIG. 42, the ventilation opening 30 is composed of an inflow ventilation opening 30a for allowing air to flow into the odor generating cartridge 1, and an outflow ventilation opening 30b for releasing the odor-containing air to the outside. An opening / closing mechanism is provided in series with these two ventilation openings 30 (30a, 30b). The specific structure of the opening / closing mechanism is not particularly limited and can be freely designed as long as it is possible to open and close the two ventilation openings 30 (30a, 30b). Specifically, as shown in FIG. 43 described later, an opening / closing mechanism composed of a sealing lid 1021 (1021a, 1021b), a shaft 1022, and a spring 1023 (1023a, 1023b) may be provided.

[0189] In this embodiment, the ventilation section 102 preferably has a two-layer structure, and in this embodiment, as shown in Figure 42, it consists of an inner layer member 31 that houses the opening and closing mechanism, and an outer layer member 32 that forms the outside of the ventilation section 102.

[0190] 42, the connecting part 103 includes at least two connecting openings 40 (40a, 40b) that communicate between the ventilation part 102 and the odor retention part 101 and are formed in the lid part 22 joined to the connecting part 103, and a partition part 41 that is arranged upstream of one of the at least two connecting openings 40 (40a, 40b). In this embodiment, the two connecting openings 40 (40a, 40b) include a first connecting opening 40a that releases air from the connecting part 103 to the odor retention part 101, and a second connecting opening 40b that releases odor-containing air from the odor retention part 101 to the connecting part 103. In this case, air that flows into connecting portion 103 through first ventilation portion 102a is released into odor retention portion 101 through first connecting opening 40a and mixes with the odor, and then the odor-containing air flows into connecting portion 103 through second connecting opening 40b and is released to the outside through second ventilation portion 102b.

[0191] In this embodiment, the partition 41 is disposed upstream of the second connecting opening 40b of the two connecting openings 40 (40a, 40b). By having the partition 41, the air that flows into the connecting portion 103 is forced to pass through the odor retention portion 101 to become odor-containing air, and then flows back into the connecting portion 103. In this embodiment, the connecting portion 103 is provided with an opening / closing mechanism in the connection area with the ventilation portion 102.

[0192] Fig. 43 is a cross-sectional view showing the state in which odor-containing air is released from the odor generating cartridge 1 of the embodiment shown in Fig. 40. In this embodiment, when the ventilation section 102 is opened while the odor is held in the odor holding section 101, air flows in from the outside. The air flows into the connecting section 103, passes through one connecting opening 40a, and sends an airflow to the odor, which is scented as the airflow passes near the impregnating material 20, causing the odor-containing air to be released. In this state, the released odor-containing air flows into the connecting section 103 through the other connecting opening 40b, and is released to the outside.

[0193] Specifically, in this embodiment, the ventilation opening 30 (30a, 30b) and the connecting portion 103 are provided with an opening / closing mechanism consisting of a sealing lid, a shaft, and a spring. These opening / closing mechanisms can be controlled, for example, by inserting a pusher X from the first sealing lid 1021a side and connecting it to the shaft, as shown in FIG. 43. Note that FIG. 43 shows only the state in which the pusher X and the shaft are connected, but when the pusher X is pressed in the state in which it is connected to the shaft, the pusher X pushes the first sealing lid 1021a toward the inside of the first ventilation portion 102a, the inflow ventilation opening 30a opens, and air flows into the first ventilation portion 102a. At this time, the first spring 1023a is compressed by the first sealing lid 1021a.

[0194] When the first sealing lid 1021a is pushed inwardly into the first ventilation part 102a, the shaft 1022 attached to the first sealing lid 1021a moves in the direction of the connecting part 103. This shaft 1022 pushes the sealing lid 1031 inwardly into the connecting part 103, and the air in the first ventilation part 102a flows into the connecting part 103. At this time, the spring 1033 is compressed by the sealing lid 1031. Because of the partition part 41, the air that flows into the connecting part 103 first flows into the odor retention part 101 through the first connecting opening 40a provided in the lid part 22, and sends the airflow to the odor retained in the odor retention part 101. As a result, the airflow is scented as it passes around the impregnating material 20, and odor-containing air is released. This odor-containing air flows again into the connecting part 103 through the second connecting opening 40b provided in the lid part 22.

[0195] When the sealing lid 1031 is pushed inwardly into the connecting portion 103, the shaft 1032 attached to the sealing lid 1031 moves in the direction of the second ventilation portion 102b. This shaft 1032 pushes the second sealing lid 1021b inwardly into the second ventilation portion 102b, and the scented air in the connecting portion 103 flows into the second ventilation portion 102b. At this time, the second spring 1023b is compressed by the second sealing lid 1021b. In this embodiment, since the second ventilation portion 102b is connected to the release ventilation opening 30b, the scent-containing air that has flowed into the second ventilation portion 102b is released to the outside through the release ventilation opening 30b. After the scent-containing air is released to the outside, the pressure on the plunger X is released, and the first sealing lid 1021a is returned to its original position by the restoring force of the first spring 1023a that has been compressed. Moreover, the sealing lid 1031 is returned to its original position by the restoring force of the spring 1033, and the second sealing lid 1021b is returned to its original position by the restoring force of the second spring 1023b.

[0196] To drive the pusher X, for example, as shown in FIG. 39, an SMA sliding part X1 that folds back and slides the shape memory alloy SMA is provided near the tip of the pusher X, and the shaft and the driving source X2 are fixed so that the pusher X is located at a position where it is connected to the shaft of the odor generating cartridge 1. A wiring capable of supplying power is connected to the driving source X2, and power may be supplied from a battery (including a storage battery) or the like through the wiring, or from a power source. The pusher X can move in the extension direction within the housing of the odor presentation unit 503 by the expansion and contraction of the shape memory alloy SMA. For example, the shape memory alloy SMA is folded back in a U-shape at a part of the SMA sliding part X1, passes through the pusher X, and both ends are fixed at the rear end of the pusher X. In this embodiment, the actuator is not limited to the shape memory alloy SMA, and may be, for example, a linear motion mechanism that linearly moves the pusher, such as a motor, a solenoid, a linear slide type, a pneumatic (air pump type), or a small electromagnet.

[0197] Figure 44 is a diagram showing a partial modification of the odor generating cartridge 1 of the embodiment shown in Figure 40. Figure 44A is a perspective view showing a partial modification of the odor retention part 101 and the connection part 103, and Figure 44B is a partial enlarged view of Figure 44A.

[0198] 44, part or all of the outer periphery of the odor retention part 101 and the connecting part 103 are provided with threaded parts 104a, 104b that are used when engaging the odor retention part 101 with the connecting part 103. By providing the threaded parts 104a, 104b, it is possible to prevent the odor generating cartridge 1 from loosening due to external stimuli such as vibration, temperature change, humidity change, etc., and to prevent odor leakage.

[0199] [Odor control unit 532] The odor control unit 532 is a unit that controls each part of the odor presentation unit 503 based on instructions from the control unit 502. The location of the odor control unit 532 is not particularly limited, and may be installed, for example, inside the housing of the odor presentation unit 503.

[0200] The odor control unit 532 controls each part of the odor presentation unit 503 so that the odor presentation condition determined by the control unit 502 is realized. Specifically, each part of the odor presentation unit 503 is controlled based on, for example, the type of odor (including the case where one type or two or more types are mixed), the amount of odor discharged, the speed of odor discharge, the strength of odor (including concentration), the direction of odor discharge, the degree of odor diffusion, the duration of odor discharge, the duration of odor discharge stop, the number of times odor discharged, the rhythm of odor discharge, the mixing ratios in the case of a mixture of two or more types of odor, or a combination of one or more of these conditions.

[0201] More specifically, for example, when changing the type of odor, the odor control unit 532 can achieve this by replacing the odor generating cartridge 1 or by placing odor presentation units 503 with different odors next to each other to mix the odors. In this case, the odor control unit 532 may mix two or more odors based on the mixing ratios of the odors when two or more odors are mixed according to the odor presentation conditions.

[0202] Furthermore, for example, when changing the amount of odor discharged, the speed of odor discharge, the strength of odor (including concentration), the degree of odor diffusion, the time period during which odor discharge is stopped, the number of times odor discharged, and the rhythm of odor discharge, the odor control unit 532 can achieve this by controlling the operation of a member related to airflow formation by linear motion of a member such as a pump. Specifically, for example, this can be achieved by changing the moving or pressing speed, moving or pressing time, moving or pressing stop time, number of times moving or pressing, etc., of a member related to airflow formation. In this case, the odor intensity may simply be changed by replacing the odor generating cartridge 1 with one with a higher concentration.

[0203] Furthermore, for example, changing the degree of diffusion of the odor, the strength of the odor, or the direction of odor emission can be achieved by linking the odor generating cartridge 1 with a blowing mechanism 506 (described later). In this case, the control unit 502 transmits instructions to each of the odor presentation unit 503 and the blowing mechanism 506 via a wired or wireless network to achieve the odor presentation conditions.

[0204] (5) Storage section 504

[0205] The storage unit 504 stores information acquired by the information acquisition unit 501 and / or information prepared in advance. The storage unit 504 also stores various information such as the result of evaluation by the control unit 502 and the desired environmental conditions set by the control unit 502. The storage unit 504 may be located within the housing of the external control unit 5022, or may be connected to the external control unit 5022 via a network and provided on a server or cloud. In this case, each user can share various information stored in the storage unit 504 on the server or cloud via the network. In consideration of the personal information of users, some information may be viewable only by those who have viewing authority.

[0206] The storage unit 504 may also perform machine learning using AI based on all stored odor presentation conditions. As a result, odors corresponding to specific targets can be presented with higher accuracy. Furthermore, the machine learning may be performed on a server or cloud, in which case each user can share the results of the machine learning present on the server or cloud via a network.

[0207] When the odor generation system 500 has a memory unit 504, the control unit 502 may determine the odor presentation conditions based on information stored in the memory unit 504. Specifically, for example, the odor presentation conditions may include a history of odor presentation conditions set for a user in the past, odor presentation conditions evaluated by the user in the past, reactions shown by the user in the past (e.g., vital data, etc.), odor presentation conditions accumulated on the cloud, odor presentation conditions based on knowledge obtained by machine learning, or a combination of one or more of these, but the present technology is not particularly limited thereto.

[0208] Furthermore, the storage unit 504 may store various types of information using one or more types of external storage devices.

[0209] (6) Output unit 505

[0210] The output unit 505 outputs information acquired by the information acquisition unit 501 and / or information prepared in advance. The output unit 505 also outputs all kinds of information, such as the result of evaluation by the control unit 502 and the desired environmental conditions set by the control unit 502. Specific examples of the output unit 505 include visual display on a monitor, a screen of a mobile information terminal, a control device used for entertainment purposes, etc.; audio output from a speaker, an earphone, a headphone, a microphone, etc.; deformation of a member, change in arrangement of a member, temperature change such as cold or warm of a member, tactile output by stimulation by a weak current, etc., or a combination of one or more of these, but are not particularly limited in the present technology.

[0211] The output unit 505 may be located inside the housing of the external control unit 5022, but may output various information using one or more types of external output devices, etc. The output unit 505 may be owned not only by the user himself / herself, but also by the user's family, a medical institution, an emergency transport facility, etc.

[0212] (7) Blower mechanism 506

[0213] The air blowing mechanism 506 is a part that assists in blowing the odor-containing air emitted from the odor presentation unit 503. Specifically, by blowing auxiliary air, an airflow is formed toward the odor presentation unit 503, and the odor presentation conditions are adjusted. By providing the air blowing mechanism 506, the determined odor presentation conditions can be realized more accurately.

[0214] The blowing mechanism 506 may be integrated with the odor presentation unit 503, or may be provided outside the odor presentation unit 503. In this embodiment, the blowing mechanism 506 may be the blowing source 90 described in "(5) Others" of "2. Second embodiment (Odor generating cartridge 1)". In addition, an air conditioner, an electric fan, a circulator, an air purifier, a humidifier, an industrial air conditioning system, or the like may be adopted as the blowing mechanism 506, and the odor presentation unit 503 may be attached to a part of the housing of these as necessary. In this case, for example, there are types of air conditioners that have only a blowing function for heating and cooling, and types that have a blowing function that is driven separately from the blowing function for heating and cooling, and the present technology can be applied to any type of air conditioner, but it is preferable to apply it to a type that has a blowing function that is driven separately from the blowing function for heating and cooling.

[0215] Furthermore, if necessary, the discharge control mechanism 52 and the direction control unit 521 described in "9. Discharge Control Mechanism" may be used, and one or more types of blower mechanisms 506 developed independently may be used.

[0216] (8)Other

[0217] The odor generation system 500 may include a warning unit (not shown) that issues a warning when, for example, information is acquired by the information acquisition unit 501 indicating that the vital signs of a specific target have significantly decreased. The warning unit may be connected to other parts of the odor generation system 500 by wire or wirelessly. In this case, the odor generation system 500 may be used to provide first aid to a specific target whose vital signs have decreased, such as emitting a strong odor or spraying a gas with a pharmacological effect. The warning unit may also automatically output current information about the specific target to the user's family, medical institutions, emergency transport facilities, etc.

[0218] Furthermore, the odor generating system 500 may include, as necessary, a reading unit that reads information from an information display unit included in the odor generating cartridge 1. Examples of the reading unit include a camera, a barcode reader, and the like. In the present technology, the reading unit is not an essential component, and information may be read from the information display unit using the information acquisition unit 501 described above.

[0219] (9) Example of Operation Flow of Odor Generation System 500

[0220] Fig. 45 is a flowchart showing an example of the operation flow of the odor generation system 500. In the odor generation system 500, first, sensing is performed using the information acquisition unit 501 to acquire information about a specific target (S101). As described above, the information referred to here may be information prepared in advance. Next, based on the acquired information, the control unit 502 determines odor presentation conditions (S102).

[0221] Here, the control unit 502 can estimate the state of the person from the acquired information and present an odor based on the estimation. For example, if the estimated state of the person is a working mode, it can present an odor that tightens the mood according to the amount of brain activity of the subject, or emit a different odor to change the mood if the subject stays in the room for a long time. Also, if the estimated state of the person is a relaxing mode, it can present an odor that calms the subject if he / she seems uneasy, or emit an odor suitable for sleep if it is detected that the subject has gone to sleep.

[0222] Although not shown, it is also possible for a specific subject to select a mode by themselves and determine the odor presentation conditions with reference to information from the information acquisition unit 501 in relation to the control unit 502. For example, if the subject selects the relax mode and the control unit 502 determines from the pulse rate that the subject is in an excited state, it is possible to change the ejection conditions so as to change the subject's state from an excited state to a calm state, or to eject an odor that the subject likes most based on knowledge obtained by machine learning using AI.

[0223] Next, the odor presentation unit 503 presents an odor from the odor presentation unit 503 based on the determined presentation conditions (S103). At this time, auxiliary air may be generated by the blower mechanism 506, and an airflow containing odor-containing air may be sent toward the position of the person sensed by an infrared sensor, for example. Next, after a certain time has elapsed since the odor was presented, the information acquisition unit 501 performs sensing again to acquire information about the specific target (S104). Based on the information acquired here, the control unit 502 evaluates whether the desired odor presentation conditions have been achieved (S105). The specific target may input the evaluation itself via the input unit.

[0224] For example, in the working mode, the control unit 502 evaluates whether or not the brain activity is increasing based on the pulse rate, and if it determines that the brain activity is increasing, it stops the odor presentation from the odor presentation unit 503 (S106). On the other hand, if the control unit 502 determines that the brain activity is not increasing, it returns to S102. Thereafter, the flow from S103 onwards is as described above.

[0225] Also, if the subject is in the relaxation mode, the control unit 502 evaluates whether the subject is calm from the pulse rate, and if it is determined that the subject is calm, stops the presentation of the odor from the odor presentation unit 503 (S106). On the other hand, if it is determined that the subject is not calm, the process returns to S102. Thereafter, the flow from S103 onwards is as described above.
