Description

[Technical field]

[0001] The present technology relates to an odor-containing air discharge control mechanism and an odor-containing air discharge control system. More specifically, the present technology relates to an odor-containing air discharge control mechanism and an odor-containing air discharge control system that are capable of controlling the discharge of odor-containing air with high accuracy. [Background technology]

[0002] Conventionally, a technology has been proposed for providing a user with a scent by supplying air to a scent holder that holds a scent and releasing the scent with the air flow. Specifically, for example, Patent Document 1 discloses a scent device having a scent head that can release gas containing a scent substance at the user's nose and can exhaust the air for deodorization.

[0003] In recent years, a technique for controlling the flow of odor-containing air when using an odor generating device has also been proposed. Specifically, for example, Patent Document 2 discloses a technique in which a first fragrance holding section and a second fragrance holding section are arranged side by side along the wind direction of a fan, and the fan sends air to a first space where the first fragrance is released and a second space where the second fragrance is released, thereby sending the fragrance toward the user. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2005-304608 A [Patent Document 2] JP 2022-131142 A Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, user needs have become more diverse, and the number of situations in which scents are used has increased. In order to deliver scent-containing air, for example, methods are used in which an aroma diffuser, air freshener, etc. is used to fill a space with scent-containing air, or a fan, aroma shooter, etc. are used to use straight air discharged from the device.

[0006] However, if the same odor fills the space, all objects in the space will smell the same odor, and if the odor is not to the taste of a particular object, it will cause discomfort to the object. In addition, when using a fan, aroma shooter, etc., the device needs to be placed in front of or on the side of a particular object, and the purpose and installation location of the device must be fixed, which makes the device for transporting odor-containing air complicated and expensive. Therefore, the technology for transporting odor-containing air is still in the process of development.

[0007] Therefore, a main object of the present technology is to provide a technology that is capable of controlling the emission of odor-containing air with high precision. [Means for solving the problem]

[0008] The present technology first provides an odor-containing air emission control mechanism comprising an odor generating cartridge having an emission portion that emits odor-containing air, and an emission control portion that has an air source that generates auxiliary air and controls the emission conditions of the odor-containing air.

[0009] The present technology also provides an odor-containing air emission control system comprising: an odor generating cartridge having an emission portion that emits odor-containing air; an emission control portion that has an air source that generates auxiliary air and controls the emission conditions of the odor-containing air; an information acquisition portion that acquires information related to a specific target; and a control portion that determines the emission conditions based on the information acquired by the information acquisition portion and / or information prepared in advance.

[0012] 1. First embodiment (discharge control mechanism 7)

[0013] (1) Configuration example of discharge control mechanism 7

[0014] Fig. 1 is a perspective view showing a first embodiment of the emission control mechanism 7. In this embodiment, the emission control mechanism 7 includes an odor generating cartridge 1 having an emission unit 14 that emits odor-containing air K (see the black arrow in Fig. 1), and an emission control unit 71 that includes an air source 711 that generates auxiliary air Y (see the white arrow in Fig. 1) and controls the emission conditions of the odor-containing air K. Furthermore, if necessary, a condition control unit 72, etc. may be included.

[0015] Each component of the discharge control mechanism 7 according to this embodiment will be described below. Note that, although some of the drawings of the embodiments described below depict the discharge control mechanism 7 with its longitudinal direction oriented horizontally, this technology allows the discharge control mechanism 7 to be used not only with its longitudinal direction oriented horizontally, but also in any other orientation, such as vertically.

[0016] (2) Odor generating cartridge 1

[0017] Fig. 2 is a cross-sectional view showing an example of an embodiment of the odor generating cartridge 1. In the present technology, the odor generating cartridge 1 is not particularly limited in other configurations as long as it has an ejection section 14 that ejects odor-containing air K, but for example, in the embodiment shown in Fig. 2, the odor generating cartridge 1 at least has 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 at least one or more spiral flow paths 131, and an ejection section 14 that communicates with the flow section 13 and ejects odor-containing air. In addition, an information display section, a pump direct drive mechanism 6, etc. may be provided as necessary.

[0018] The material for forming the housing 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.

[0019] Furthermore, in this embodiment, the odor-generating cartridge 1 has a shape that combines multiple approximately cylindrical shapes with different diameters, as shown in Figure 2, but 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 it can be an approximately cylindrical shape, an approximately elliptical cylindrical shape, an approximately triangular cylindrical shape, an approximately square cylindrical shape, etc. (including those with rounded corners), an approximately conical shape, an approximately polygonal pyramid shape with a cross section of approximately a triangle, approximately a square, etc. (including those with rounded corners), etc., or a freely combined shape of one or more of these. Each part of the odor generating cartridge 1 according to this embodiment will be described below.

[0020] (2-1) Odor retention section 11

[0021] The odor retention section 11 is a portion that retains an odor. 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 odor 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, it can stimulate via olfactory receptors and also stimulate a cold sensation via trigeminal receptors (TRPA1 channel), and therefore is included in the term "odor."

[0022] 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.

[0023] 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.

[0024] 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.).

[0025] 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 support 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.

[0026] In this embodiment, the impregnating material is in sheet form, as shown in Fig. 2, and is rolled into a substantially 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. 2 has a single-layer structure, it is also possible to stack multiple layers and store them in the odor generating cartridge 1 as necessary.

[0027] The odor retained in the impregnating material is not particularly limited as long as it is a component that can generate an odor (hereinafter, also referred to as "flavor"). Specifically, liquid flavors, powder flavors, etc., either as is or dissolved or dispersed in a suitable solvent, essential oils, essential oils diluted in a suitable solvent, fruit juice, food and drink, or dissolved or dispersed in a suitable solvent, etc., or any combination of one or more of these may be used.

[0028] The impregnating material may hold components other than the component capable of generating an odor, such as a component that produces a pharmacological effect when inhaled. If the only purpose is to produce a pharmacological effect, the impregnating material may be impregnated only with a component that produces a pharmacological effect when inhaled, rather than with a component capable of generating an odor.

[0029] Furthermore, if necessary, the impregnating material may not retain any component capable of generating an odor, and odorless air may be discharged using the mechanism of the odor generating cartridge 1. In addition, in the discharge control mechanism 7, only the operation of the odor generating cartridge 1 may be turned OFF, and only the operation of the air source 711 described below may be turned ON, generating only the auxiliary air Y from the air source 711. Furthermore, in this case, only the odorless air or the auxiliary air Y may be used for purposes such as an air curtain.

[0030] (2-2) Ventilation section 12

[0031] 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.

[0032] 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.

[0033] 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.

[0034] The arrow in Fig. 2 indicates the pressing direction of the pump portion 61. In this embodiment, the ventilation portion 12 is opened and closed using the pump linear motion mechanism 6. The mechanism by which a part of the odor generating cartridge 1 is opened and closed using the pump linear motion mechanism 6 will be described later in "(2-6) Pump linear motion mechanism 6".

[0035] (2-3) Flow section 13

[0036] 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.

[0037] In this embodiment, the flow section 13 particularly includes two spiral flow paths 131. In this case, as shown in Fig. 2, 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 located 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 paths 131 and the odor retention section 11, so that the odor can be imparted to the air more efficiently.

[0038] In this embodiment, 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.

[0039] (2-4) Discharge part 14

[0040] The discharge section 14 is a section that discharges the odor-containing air K. In this embodiment, the discharge section 14 is in communication with the flow section 13. Note that the "outside" referred to here also includes the concept of a specific space, a specific place, and the like.

[0041] In the odor generating cartridge 1 shown in this embodiment, the odor-containing air K is discharged by pressing a part of the ventilation part cover 121 from the ventilation part 12 side of the cartridge 1. In this case, the ventilation part cover 121 pressed through the ventilation part 12 opens the discharge part cover 141 through the shaft 130. As a result, the air flowing in from the ventilation part 12 flows through the flow part 13, and the odor-containing air K reaches the discharge part 14 through the opened discharge part cover 141, and the odor-containing air K is discharged from the discharge part 14. After the odor-containing air K is discharged, the discharge part cover 141 and the ventilation part cover 121 return to their original positions due to the restoring forces of the discharge part spring 142 and the ventilation part spring 122.

[0042] 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 in the housing of the odor generating cartridge 1. This makes it possible to generate odor-containing air K efficiently even in a limited space.

[0043] (2-5) Information display section

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] Markers and LED lights formed in one or more colors may be used simply for design purposes.

[0050] (2-6) Pump direct acting mechanism 6

[0051] 3 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 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.

[0052] The pump linear motion mechanism 6 includes at least a pump section 61, a sealing section 62, and a linear motion source 63. If necessary, other parts may be included. As shown in FIG. 3, 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 members selected from the group consisting of the vent cover 121, the discharge cover 141, and a member 64 provided between the pump section 61 and the cartridge 1, thereby opening and closing them. After the odor generating cartridge 1 opens in accordance with the movement of the pump section 61, it is possible to prevent the intrusion of excess outside air, dust, etc. by providing a sealing section 62 at an appropriate location as shown in FIG. 3.

[0053] 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.

[0054] 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.

[0055] 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 the "linear motion" mentioned here includes not only a case where one member moves in a linear direction, but also a case where some of multiple connected members move in a linear direction.

[0056] In addition, in the present technology, as the linearly moving source 63, an axial flow from an air source 711 may be used as described later in "5. Fifth embodiment (discharge control mechanism 7)".

[0057] Fig. 4 is a perspective view showing an example of an embodiment in which a pump linear motion mechanism 6 is used together with the odor generating cartridge 1 of the embodiment shown in Fig. 2. Fig. 5 is a cross-sectional view of the embodiment shown in Fig. 4. The pump linear motion mechanism 6 of the embodiment shown in Fig. 4 includes the 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. 4), and a linear motion source 63 that linearly moves the pump section 61.

[0058] In this embodiment, the direct-acting movable source 63 uses a DC motor, and the pump section 61 is moved by the movement of the DC motor. 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 bent end abuts against a part of the ventilation section cover 121, and the ventilation section cover 121 is moved directly. In this manner, in this technology, the shape of the pump section 61 may be devised according to the space in which the odor generating cartridge 1 is to be installed. In addition, the pump section 61 may be formed into one block by joining a plurality of members as shown in this embodiment. In this embodiment, a sealing section 62 is formed on a part of the ventilation section cover 121 on the side abutting against the pump section 61.

[0059] In addition, in the present technology, any one or more selected from the group consisting of the lid portion 121 for the ventilation portion, the lid portion 141 for the discharge portion, and the member 64 provided between the pump portion 61 and the cartridge 1 may be opened and closed by a mechanism other than the pump linear motion mechanism 6, for example, by using a link structure consisting of a shape memory alloy SMA and one or more links, or by using a twisted string actuator (TSA, also called a twisted string actuator).

[0060] FIG. 6 is a perspective view showing a mechanism 8 using a TSA. The TSA at least includes a motor, a rotating member, two strings or wires, and a guide portion for guiding the two strings or wires. The motor rotates the rotating member, which causes the two strings or wires to twist with each other. Therefore, the length of the string or wire in the twisted region when the twist occurs is shorter than that 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. In the embodiment shown in FIG. 6, at least a TSA 81 and a return spring (compression spring) 82 on the outer periphery of the TSA 81 are included. By driving the motor, the two strings or wires that are components of the TSA are twisted to open and close the valve 83. In addition, 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 can be reduced.

[0061] (2-7)Other

[0062] 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.

[0063] In addition, the odor generating cartridge 1 can be a replaceable disposable type, which can improve usability.

[0064] 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 formed in part or in whole from 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.

[0065] FIG. 7 is a cross-sectional view showing an example of an embodiment of the deodorizing mechanism 51. The odor generating cartridge 1 may include the deodorizing mechanism 51 as necessary. Specifically, for example, the deodorizing mechanism 51 may be arranged to take deodorizing measures against the suction hole 612 of the pump linear motion mechanism 6 described above. By taking deodorizing measures against the suction hole 612, when odors from components such as resin or the surrounding environment invade (see the black arrow in FIG. 7), the odor-containing air K is deodorized before it is generated (see the gray arrow in FIG. 7 for the air after deodorization), and the odor that is originally intended to be presented can be presented. The deodorizing mechanism 51 includes, for example, a front member 511 and a rear member 512, and has a deodorizing material part 513 between the front member 511 and the rear member 512 that are fitted together.

[0066] Materials for forming the front member 511 and the rear member 512 include, for example, glass; metals such as stainless steel (SUS (Steel Use Stainless)) and aluminum; resins such as polycarbonate, polyvinyl chloride, polyethylene, phenol resin, olefin resin, acrylic resin, urethane resin, ABS resin, polyether ether ketone resin, polyacetal resin, fluororesin, cycloolefin polymer resin, and polyimide resin; or one or more of these can be freely combined. The shapes of the front member 511 and the rear member 512 can be, for example, an approximately polygonal shape such as an approximately triangular prism or an approximately square prism, an approximately cylindrical shape, an approximately elliptical cylinder, or the like, or one or more of these can be freely combined. In the case of an approximately polygonal shape, the corners may be rounded, or a taper or a step may be provided in a part of the front member 511 or the rear member 512.

[0067] The deodorizing material part 513 may be, for example, a gas adsorbing substance woven or kneaded into the material, or 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 (e.g., palm, fir, bamboo, resin, wood, fiber, coal, etc.), zeolite, layered compounds (e.g., 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 part 513 may be, for example, powder, granules, fiber, molded product, sheet (e.g., nonwoven fabric, woven fabric, etc.), rod, plate, etc. Furthermore, the surface of the deodorizing material part 513 may be subjected to activation treatment or not, and may be subjected to, for example, surface functional group exposure treatment (e.g., acidification, alkalization, polarization, depolarization, etc.).

[0068] In addition, the deodorizing mechanism 51 may have one or more fall prevention parts 5131 that prevent the deodorizing material part 513 from falling. For example, a mesh structure, a filter structure, or the like formed into a sheet can be used as the fall prevention part 5131. This not only provides the effect of preventing the fall, but also prevents the pump part 61 from absorbing gas adsorbent substances formed of powder, granules, or the like such as activated carbon. It is preferable that the fall prevention part 5131 is attached to the deodorizing material part 513 using an adhesive or the like so that no gap is generated. In addition, an attachment part 515 for attaching the deodorizing mechanism 51 to another member, a housing, or the like may be formed on the surface of the rear member 512 that is not fitted to the front member 511. The attachment part 515 can be formed, for example, with an adhesive, double-sided tape, or the like.

[0069] (3) Discharge control unit 71

[0070] The discharge control unit 71 has an air source 711 that generates auxiliary air Y, and is a part that controls the discharge conditions of the odor-containing air K. In this technology, by providing the discharge control unit 71, the auxiliary air Y can be used, so that the odor-containing air K can be made directional, and the amount of the odor-containing air K can be adjusted to transport the odor-containing air K at a low concentration for a long time over a wide area. Furthermore, it is possible to prevent the odor-containing air K from reaching certain locations, and to meet the need to reduce lingering odor.

[0071] In addition, since the discharge control mechanism 7 according to the present technology uses the odor generating cartridge 1, it is possible to instantly switch between multiple odors, and by controlling the amount of odor discharged by the discharge control unit 71, it is possible to reduce the frequency of replacing the cartridge 1 itself. Furthermore, since the discharge control unit 71 can also locally control each part, problems such as odor leakage and odor mixing are unlikely to occur. As will be described later, the discharge control mechanism 7 according to the present technology can also be controlled via a network.

[0072] In addition, in the past, if the same odor was filled in a space, there was a problem that if the odor was not to the taste of a particular target, the target would feel uncomfortable. However, in this technology, the odor-containing air K has directionality, and the concentration and discharge distance can be adjusted, so the above-mentioned problems are unlikely to occur. Furthermore, when using a fan, aroma shooter, etc., it was necessary to place the device on the front or side of a specific target, but in this technology, the miniaturized discharge control mechanism 7 makes it unnecessary to fix the purpose, location, etc. of the device. In other words, the purpose and location of the discharge control mechanism 7 can be freely changed according to the needs of the user.

[0073] The air blowing source 711 that generates the auxiliary air Y is not particularly limited as long as it can generate the auxiliary air Y, and for example, an axial fan, a blower fan, a centrifugal fan, or one or more of these can be used in combination. The air blowing source 711 may also be a combination of a diaphragm pump, a diaphragm pump using a piezoelectric element or a motor (for example, a microblower, etc.), and an airflow expansion mechanism. An air conditioner, an electric fan, a circulator, an air purifier, a humidifier, an industrial air conditioning system, or one or more of these can be used in combination. Furthermore, the above-mentioned air conditioner, etc. may be used as the airflow expansion mechanism.

[0074] The conditions for ejecting the odor-containing air K include, for example, one or more selected from the group consisting of the type of odor (including the concept of an odor that is a mixture of two or more fragrances), ejection direction, ejection distance, ejection amount, ejection speed, ejection location, and diffusion range (including the concept of ejection range) of the odor-containing air K.

[0075] Note that a specific example of control of the discharge conditions in this embodiment will be described later in "(6) Example of Discharge Control by Discharge Control Mechanism 7".

[0076] (4) Condition control section 72

[0077] FIG. 10 is a block diagram showing an example of the concept of the discharge control mechanism 7. The condition control unit 72 is a part that controls at least the discharge control unit 71. In addition to the discharge control unit 71, the condition control unit 72 may also control the odor generating cartridge 1 as necessary. The condition control unit 72 is not an essential structure in the present technology, but by providing the condition control unit 72, the discharge conditions can be automatically controlled, improving usability. In the present technology, regardless of whether the condition control unit 72 is provided, the user may manually control the discharge conditions as necessary.

[0078] In this embodiment, the condition control unit 72 may also have a memory unit 73 that stores various information, an input unit 74 that accepts instructions from a user, and an output unit 75 that outputs various information. In this case, the condition control unit 72, the memory unit 73, the input unit 74, and the output unit 75 may be provided in the housing of the odor generating cartridge 1, the housing of the discharge control mechanism 7, a smartphone, a tablet terminal, a wearable terminal, a personal computer, or the like, and each part can communicate with each other via a wired or wireless (for example, Wi-Fi, Bluetooth, etc.) network.

[0079] The condition control unit 72 determines suitable ejection conditions based on, for example, user information input from the input unit 74 and the user's usage history stored in the storage unit 73, and controls the ejection control unit 71 and / or the odor generating cartridge 1 to satisfy the determined suitable ejection conditions. Specific examples of control of the ejection conditions will be described later in "(6) Examples of ejection control by the ejection control unit 71."

[0080] Further, the condition control unit 72 may store the evaluation result of the discharge conditions input by the user in a storage unit 73, and the condition control unit 72 may perform feedback control on the discharge control unit 71 based on the evaluation result of the discharge conditions. Note that a part or the whole of the storage unit 73 may be on a server or a cloud system connected via the Internet, and in this case, machine learning using an AI 76 may be performed based on information accumulated in the server or the cloud system.

[0081] Furthermore, the condition control unit 72 can also simultaneously or continuously control multiple odor generating cartridges 1 and / or ejection control units 71 via a network. As a result, even if the odor generating cartridges 1 and ejection control units 71 are provided in multiple locations, the ejection control mechanisms 7 can be collectively controlled by the condition control unit 72 connected to them. The "control" referred to here includes turning the drive source on or off, changing the ejection conditions in each ejection control mechanism 7, etc., and is performed on at least one ejection control mechanism 7 selected by the user.

[0082] (5)Other

[0083] In this technology, the discharge control unit 71 includes an air blowing source 711, but there is a problem that noise may be generated depending on the type of air blowing source 711, the number of air blowing sources 711 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.

[0084] Specifically, as shown in Fig. 8, 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, thereby 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.

[0085] 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 technology is not particularly limited to this. In addition, the balloon may be provided with a check valve as shown in FIG. 8.

[0086] As another solution, for example, as shown in Fig. 9, pressure can be stored in a balloon with the operating voltage of the blower source relatively lowered, and released when air is to be discharged, making it possible to provide a low-noise blower source. Note that Fig. 9A is a schematic diagram showing an example of an embodiment of the blower source from the front, and Fig. 9B is a schematic diagram showing the back side of Fig. 9A. Also, based on a similar principle, low noise can be achieved by using a syringe action by a linear actuator. Also, the balloon in Fig. 9B may be provided with a check valve (not shown).

[0087] 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.

[0088] (6) Example of discharge control by discharge control mechanism 7

[0089] As described above, Fig. 1 is a perspective view showing a first embodiment of the emission control mechanism 7. In this embodiment, the emission control mechanism 7 includes an odor generating cartridge 1 having an emission unit 14 that emits odor-containing air K (see the black arrow in Fig. 1), and an emission control unit 71 that includes an air source 711 that generates auxiliary air Y (see the white arrow in Fig. 1) and controls the emission conditions of the odor-containing air K.

[0090] In this embodiment, the odor-containing air K and the auxiliary air Y travel in approximately the same direction and mix together. This occurs because the auxiliary air Y, which has a larger flow rate and a faster flow speed than the odor-containing air K, is released near the discharge portion 14, and the odor-containing air K, which travels in approximately the same direction as the auxiliary air Y, is caught up in and pulled by the auxiliary air Y. This makes it possible to give directionality to the odor-containing air K and deliver the odor-containing air K far away. It is also possible to prevent the odor-containing air K from stagnation, and as a result, it is possible to prevent odor from remaining mainly inside and around the exterior of the odor generating cartridge 1.

[0091] Furthermore, in this embodiment, there are no other components at the destination where the odor-containing air K is discharged and at the destination where the auxiliary air Y is released.In other words, it is possible to control the discharge conditions without using other components at the destination and the release destination, so that discharge control can be achieved in a space-saving manner.

[0092] In this embodiment, there is further provided a flow passage (duct) 712 that continues from the air blowing source 711 to the outlet of the discharge control unit 71. Since there are no other members or the like in the flow passage 712, the auxiliary air Y generated from the air blowing source 711 can be efficiently discharged.

[0093] In the present technology, various shapes can be adopted as the shape of the flow passage 712 as shown in each embodiment described later, and an appropriate shape can be freely selected depending on the intended use, etc. Furthermore, the flow passage 712 may have a curvature on at least a part of the side surface according to the shape of the odor generating cartridge 1, etc., as shown in FIG.

[0094] In addition, it is preferable that the flow passage 712 gradually narrows toward the outlet. This can impart momentum to the discharge of the auxiliary air Y, and efficiently draw in the odor-containing air K. Note that "gradually narrows" here means that the cross-sectional area (longitudinal cross-sectional area) in the direction perpendicular to the longitudinal direction of the flow passage 712 gradually decreases. This therefore includes a form in which only the horizontal width of the flow passage 712 gradually decreases, and a form in which only the vertical width of the flow passage gradually decreases.

[0095] 2. Second embodiment (discharge control mechanism 7)

[0096] Fig. 11A is a front view showing a second embodiment of the discharge control mechanism 7, and Fig. 11B is a diagram showing the discharge of odor-containing air K and the release of auxiliary air Y. Fig. 12 is a cross-sectional view of the embodiment shown in Fig. 11. In this embodiment, the discharge control mechanism 7 is equipped with an odor generating cartridge 1 having a discharge section 14 that discharges odor-containing air K, an air source 711 that generates auxiliary air Y, and a discharge control section 71 that controls the discharge conditions of the odor-containing air K, and a pump direct drive mechanism 6 that opens and closes the odor generating cartridge 1. In addition, the odor-generating cartridge 1 is the same as that described in the above-mentioned "(2) Odor-generating cartridge 1," and the pump direct-acting mechanism 6 is the same as that described in the above-mentioned "(2-6) Pump direct-acting mechanism 6," so explanations are omitted here.

[0097] In this embodiment, similarly to the first embodiment described above, the flow passage 712 gradually narrows from the air source 711 toward the outlet, resulting in a smaller cross-sectional area of ​​the outlet. Therefore, in this embodiment as well, it is possible to impart momentum to the outlet of the auxiliary air Y, and to efficiently draw in the odor-containing air K.

[0098] In the present technology, as shown in this embodiment, the discharge section 14 is on approximately the same plane as the outlet of the discharge control section 71 (in this embodiment, the outlet of the flow passage 712). This allows the auxiliary air Y to more efficiently draw in and pull the odor-containing air K. This is particularly effective in the case of having a flow passage 712 capable of discharging the auxiliary air Y with a large flow rate and a fast flow speed, as shown in B of Fig. 11.

[0099] Furthermore, in the present technology, the discharge section 14 may protrude in the traveling direction of the odor-containing air K beyond the discharge port of the discharge control section 71 (the flow path 712 in this embodiment). Even in this case, as described above, it is particularly effective when the auxiliary air Y has a flow path 712 capable of more efficiently drawing in and pulling the odor-containing air K and discharging the auxiliary air Y with a large flow rate and a fast flow rate. In this case, it is preferable that the distance in the protruding direction between the position of the discharge port of the discharge control section 71 and the position of the discharge section 14 of the odor generating cartridge 1 is not so far apart. Specifically, the distance in the protruding direction between the position of the discharge port and the position of the discharge section 14 is, for example, preferably 3 cm or less, and more preferably 1 cm or less.

[0100] In this embodiment, the outlet of the flow path 712 is formed in the upper part of the discharge part 14, as shown in A of Fig. 11. In this case, the flow path 712 may be formed continuously in the longitudinal direction of the odor generating cartridge 1, as shown in Fig. 12. This makes it possible to discharge auxiliary air Y with a large flow rate and a fast flow speed, as shown in B of Fig. 11. Therefore, when it is desired to extend the discharge distance of the odor-containing air K, it is preferable to adopt the configuration of the flow path 712 of this embodiment.

[0101] Although not shown, in the present technology, the discharge port of the flow path 712 may be formed continuously only at the lower part of the discharge part 14, or may be formed continuously at both the upper and lower parts.

[0102] 3. Third embodiment (discharge control mechanism 7)

[0103] Fig. 13A is a front view showing a third embodiment of the discharge control mechanism 7, and Fig. 13B is a diagram showing the discharge of odor-containing air K and the release of auxiliary air Y. Fig. 14 is a cross-sectional view of the embodiment shown in Fig. 13. In this embodiment, the discharge control mechanism 7 is equipped with an odor generating cartridge 1 having a discharge section 14 that discharges odor-containing air K, an air source 711 that generates auxiliary air Y, and a discharge control section 71 that controls the discharge conditions of the odor-containing air K, and a pump direct drive mechanism 6 that opens and closes the odor generating cartridge 1. In addition, the odor-generating cartridge 1 is the same as that described in the above-mentioned "(2) Odor-generating cartridge 1," and the pump direct-acting mechanism 6 is the same as that described in the above-mentioned "(2-6) Pump direct-acting mechanism 6," so explanations are omitted here.

[0104] In this embodiment, compared to the second embodiment described above, the flow passage 712 is gradually narrowed from the air blower 711 toward the outlet, and as a result, the cross-sectional area of ​​the outlet is further reduced.

[0105] However, if the air volume of the air blowing source 711 is lost, the air speed becomes small as shown in B of Fig. 13. Therefore, in this technology, it is necessary to thoroughly consider the relationship between the type and performance of the air blowing source 711 and the shape of the flow passage 712 according to the technical common sense of a person skilled in the art.

[0106] It is also important to select air blower source 711 while also taking noise reduction into consideration, and to design the shape of air flow path 712 that is compatible with selected air blower source 711. Note that, in order to reduce noise, one method is to make the fan that forms air blower source 711 larger, but if miniaturization is given priority, one method is to lower the voltage and reduce the fan rotation speed.

[0107] When the type and performance of the air source 711 are well matched with the shape of the air flow passage 712, the auxiliary air Y with a large flow rate and a fast flow velocity can be more efficiently discharged. In addition, in this case, the tip portion can be made small, which can save space.

[0108] 4. Fourth embodiment (discharge control mechanism 7)

[0109] Fig. 15A is a front view showing a fourth embodiment of the discharge control mechanism 7, and Fig. 15B is a diagram showing the discharge of auxiliary air Y. Fig. 16 is a cross-sectional view of the embodiment shown in Fig. 15. In this embodiment, the discharge control mechanism 7 is equipped with an odor generating cartridge 1 having a discharge section 14 that discharges odor-containing air K, an air source 711 that generates auxiliary air Y and is equipped with a discharge control section 71 that controls the discharge conditions of the odor-containing air K, and a pump direct drive mechanism 6 that opens and closes the odor generating cartridge 1. In addition, the odor-generating cartridge 1 is the same as that described in the above-mentioned "(2) Odor-generating cartridge 1," and the pump direct-acting mechanism 6 is the same as that described in the above-mentioned "(2-6) Pump direct-acting mechanism 6," so explanations are omitted here.

[0110] In this embodiment, the outlet of the flow passage 712 is formed around the discharge portion 14 as shown in A of Fig. 15. In this case, the shape of the outlet is not particularly limited as long as it is formed around the discharge portion 14, but it is preferable that the outlet is formed in a substantially annular shape as shown in A of Fig. 15. Note that "formed around" here includes not only the case where it is formed continuously as shown in A of Fig. 15, but also the case where it is formed discontinuously around the discharge portion 14.

[0111] Forming the outlet of the flow passage 712 around the discharge part 14 is effective when it is desired to sufficiently mix and discharge the odor-containing air K and the auxiliary air Y. In this embodiment, the travel distance of the gas containing the odor-containing air K can be made longer compared to the second embodiment described above.

[0112] 5. Fifth embodiment (discharge control mechanism 7)

[0113] Fig. 17A is a front view showing a fifth embodiment of the discharge control mechanism 7, and Fig. 17B is a diagram showing the state of release of auxiliary air Y. Also, Fig. 18 is a cross-sectional view of the embodiment shown in Fig. 17. In this embodiment, the discharge control mechanism 7 is equipped with an odor generating cartridge 1 having a discharge part 14 that discharges odor-containing air K, an air source 711 that generates auxiliary air Y and is equipped with a discharge control part 71 that controls the discharge conditions of the odor-containing air K, and a pump direct drive mechanism 6 that opens and closes the odor generating cartridge 1. Incidentally, the odor generating cartridge 1 is similar to that described above in “(2) Odor generating cartridge 1”, and therefore a description thereof will be omitted here.

[0114] In this embodiment, as shown in A of Fig. 17, four discharge ports of the communication flow paths 712 are discontinuously formed around the discharge portion 14 (specifically, at the four corners of the housing of the discharge control mechanism 7). In this case, two or more communication flow paths 712 may be formed continuously in the longitudinal direction of the odor generating cartridge 1 and the pump portion 61, as shown in Fig. 18. This makes it possible to reduce the cross-sectional area of ​​the surface perpendicular to the longitudinal direction of the discharge control mechanism 7 in the entire discharge control mechanism 7, thereby enabling space saving in a predetermined direction.

[0115] In this embodiment, the axial flow from the air source 711 is used instead of the linear motion source 63 of the pump linear motion mechanism 6, and the axial flow can move the pump section 61 in the linear motion direction to open and close the vent cover section 121. This can reduce the number of parts, simplify the manufacturing process, and reduce costs.

[0116] 6. Sixth embodiment (discharge control mechanism 7)

[0117] (1) Discharge control mechanism 7 according to the sixth embodiment

[0118] Fig. 19 is a front view showing a sixth embodiment of the emission control mechanism 7, and Fig. 20 is a cross-sectional view of the embodiment shown in Fig. 19. In this embodiment, the emission control mechanism 7 includes four odor generating cartridges 1 having emission sections 14 that emit odor-containing air K, and one air source 711 that generates auxiliary air Y, an emission control section 71 that controls the emission conditions of the odor-containing air K, and a pump direct drive mechanism 6 that opens and closes the odor generating cartridges 1. The odor generating cartridge 1 is the same as that described in the above-mentioned "(2) Odor generating cartridge 1", and therefore the description thereof will be omitted here. Also, in Fig. 20, the illustration of the ventilation part cover 121, the ventilation part spring 122, the discharge part cover 141, and the discharge part spring 142 will be omitted.

[0119] In this embodiment, one air blowing source 711 is provided for multiple odor generating cartridges 1. By providing multiple odor generating cartridges 1, it is possible to mix two or more types of fragrances, adjust the amount of odor-containing air K discharged, and diffuse the odor-containing air K over a wide area.

[0120] In this embodiment, the plurality of odor generating cartridges 1 may all be in operation, or only some of them may be in operation, and when the fragrance runs out, the next cartridge 1 may be in operation. When only some of them are in operation, it is possible to cope with continuous use for a long time.

[0121] In this embodiment, as shown in Fig. 20, one air blowing source 711 is provided at the center of the rear side of the multiple odor generating cartridges 1, and the outlet of the communication flow path 712 is provided at the center of the four odor generating cartridges 1, as shown in Fig. 19 and Fig. 20. This allows the auxiliary air Y emitted from the air blowing source 711 to efficiently mix with the odor-containing air K discharged from each odor generating cartridge 1.

[0122] In this embodiment, similarly to the fifth embodiment, an axial flow from an air source 711 is used instead of the linear motion source 63 of the pump linear motion mechanism 6, and the axial flow can move the pump section 61 in the linear motion direction to open and close the vent cover section 121. This can reduce the number of parts, simplify the manufacturing process, and reduce costs.

[0123] (2) Modification of the discharge control mechanism 7 according to the sixth embodiment

[0124] Fig. 21 is a front view showing a modification of the sixth embodiment of the discharge control mechanism 7, and Fig. 22 is an explanatory diagram showing a state in which the main flow and the side flow are mixed together. This modification has the same configuration as that shown in the sixth embodiment, except for the flow passage 712.

[0125] In this modified example, as shown in Fig. 21, one air source 711 is provided at the center of the rear side of multiple odor generating cartridges 1. Also, as shown in Fig. 21, a communication flow path 712 is formed in the center of four odor generating cartridges 1, and smaller communication flow paths 712 are formed in the corners of each odor generating cartridge 1 compared to the communication flow path 712 formed in the center.

[0126] In this modification, by changing the size of the outlets of the multiple flow paths 712, the auxiliary airflow Y generated from the air source 711 can be discharged from the multiple outlets as shown in A of FIG. 22 to form a main flow Y1 and one or more side flows Y2. The side flow Y2 advances in the direction of the arrow shown in A of FIG. 22 due to the Coanda effect, and moves toward the main flow Y1 while entraining the odor-containing air K discharged from the discharge unit 14. In this way, the present technology can contribute to the control of the discharge conditions by entraining the odor-containing air K, adjusting the wind direction, and concentrating the wind by utilizing the Coanda effect. In this embodiment, as shown in B of FIG. 22, multiple winds can be mixed in the air, and a wind in which the odor-containing air K and the auxiliary air Y are efficiently mixed can be generated.

[0127] 7. Seventh embodiment (discharge control mechanism 7)

[0128] Fig. 23 is a front view showing a seventh embodiment of the emission control mechanism 7, and Fig. 24 is a cross-sectional view of the embodiment shown in Fig. 23. In this embodiment, the emission control mechanism 7 includes four odor generating cartridges 1 having emission sections 14 that emit odor-containing air K, and one air source 711 that generates auxiliary air Y, an emission control section 71 that controls the emission conditions of the odor-containing air K, and a pump direct drive mechanism 6 that opens and closes the odor generating cartridges 1. In addition, the odor-generating cartridge 1 is the same as that described in the above-mentioned "(2) Odor-generating cartridge 1," and the pump direct-acting mechanism 6 is the same as that described in the above-mentioned "(2-6) Pump direct-acting mechanism 6," so explanations are omitted here.

[0129] In this embodiment, similarly to the sixth embodiment, one air source 711 is provided for the plurality of odor generating cartridges 1. By providing a plurality of odor generating cartridges 1, it is possible to mix two or more types of fragrances, adjust the discharge amount of the odor-containing air K, and diffuse the odor-containing air K over a wide range.

[0130] In this embodiment, the plurality of odor generating cartridges 1 may be all in operation, or only some of them may be in operation, and when the fragrance runs out, the next cartridge 1 may be in operation. When only some of them are in operation, it is possible to cope with continuous use for a long time.

[0131] In this embodiment, as shown in Fig. 23, four odor generating cartridges 1 are arranged in a row, and as shown in Fig. 24, one air source 711 is provided on the upper surface of the multiple odor generating cartridges 1, and the outlet of the flow path 712 is also provided on the upper surface of the multiple cartridges 1. As a result, similar to the sixth embodiment, the auxiliary air Y emitted from the air source 711 is efficiently mixed with the odor-containing air K discharged from each odor generating cartridge 1.

[0132] 8. Eighth embodiment (discharge control mechanism 7)

[0133] Fig. 25 is a perspective view showing an eighth embodiment of the discharge control mechanism 7, and Fig. 26 is an explanatory diagram explaining an example of use of the embodiment shown in Fig. 25. The arrow in Fig. 26 indicates the direction in which the auxiliary air Y is discharged. In this embodiment, the odor generating cartridge 1 and the pump direct acting mechanism 6 are built into a substantially rectangular cylindrical housing, and are configured to discharge the odor-containing air K through a hole 140 communicating with the discharge section 14. In addition to the odor generating cartridge 1 and the pump direct acting mechanism 6, the discharge control mechanism 7 is equipped with an air source 711 that generates the auxiliary air Y, and a discharge control section 71 that controls the discharge conditions of the odor-containing air K. In addition, the odor-generating cartridge 1 is the same as that described in the above-mentioned "(2) Odor-generating cartridge 1," and the pump direct-acting mechanism 6 is the same as that described in the above-mentioned "(2-6) Pump direct-acting mechanism 6," so explanations are omitted here.

[0134] 25 and 26, the discharge control unit 71 includes a direction control unit 713a that is equipped with a plurality of propellers 7131 and that can move in the vertical direction (horizontal direction) at the tip of a passage 712 through which the auxiliary air Y generated from the air blowing source 711 flows. In this manner, by using the direction control unit 713, the direction control unit 713a can be swung in a desired direction such as the vertical direction to control the release direction of the auxiliary air Y flowing through the passage 712.

[0135] 26A and 26B, the present embodiment may include a direction control unit 713b, which can move left and right (vertically) as shown in the change from A to B of Fig. 26A, and can control the left and right direction of the auxiliary air Y emitted from the air source 711. In Fig. 26, the flow path 712 is formed by the direction control unit 713b itself, that is, the direction of emission of the auxiliary air Y can be controlled by swinging the entire flow path 712 (direction control unit 713b) left and right to a desired direction.

[0136] In addition, in A of FIG. 26, the propeller 7131 does not have a movable source, rotates when the auxiliary wind Y hits it, and can be used to adjust the wind speed as necessary.

[0137] In this embodiment, the direction control unit 713 may be composed of only the direction control unit 713a operable in the up-down direction, or only the direction control unit 713b operable in the left-right direction, but by being composed of the direction control units 713a and 713b, the emission direction of the auxiliary air Y can be changed to any direction, up-down, left-right, or a combination of these, such as upper right, lower right, upper left, lower left, etc. Accordingly, the discharge direction of the odor-containing air K can also be changed to a desired direction.

[0138] The direction control unit 713 is basically electrically operable, but in some cases, a unit that moves automatically by the auxiliary wind Y from the air blowing source 711 may be used. Specifically, for example, a louver that automatically rotates by the auxiliary wind Y can be used as the direction control unit 713 in order to diffuse the auxiliary wind Y over a wide range. It is also possible for the user to manually operate the direction control unit 713.

[0139] In addition, when the direction control unit 713 is operated electrically, as shown in A and B of Figures 26, particularly in the case of a flap-type direction control unit 713, the direction control unit 713b can be operated in a predetermined direction by turning on the movable source of the actuator having the shape memory alloy SMA and the air source 711 for a predetermined time, and then by turning off the movable source for a predetermined time, the direction control unit 713b can be moved in a direction different from the predetermined direction due to the natural contraction of the shape memory alloy SMA.

[0140] 9. Ninth embodiment (discharge control mechanism 7)

[0141] Fig. 27 is a front perspective view showing a ninth embodiment of the discharge control mechanism 7, and Fig. 28 is a rear perspective view showing the ninth embodiment of the discharge control mechanism 7. In this embodiment, the odor generating cartridge 1 and the pump linear motion mechanism 6 are built into a substantially rectangular cylindrical housing, and are configured to discharge odor-containing air K from the discharge section 14 through multiple holes 140. In addition to the odor generating cartridge 1 and the pump linear motion mechanism 6, the discharge control mechanism 7 also includes an air source 711 that generates auxiliary air Y, and a discharge control section 71 that controls the discharge conditions of the odor-containing air K. In addition, the odor-generating cartridge 1 is the same as that described in the above-mentioned "(2) Odor-generating cartridge 1," and the pump direct-acting mechanism 6 is the same as that described in the above-mentioned "(2-6) Pump direct-acting mechanism 6," so explanations are omitted here.

[0142] 27 and 28, the discharge control unit 71 has a direction control unit 713c at the tip of the flow passage 712 through which the auxiliary air Y generated from the air blowing source 711 flows. The direction control unit 713c in this embodiment is a louver having a structure in which flaps move up, down, left, and right. By using this, the up, down, left, and right directions of the auxiliary air Y generated from the air blowing source 711 can be controlled.

[0143] In addition, in this embodiment, as described later, the flow passage 712 is formed by a plurality of direction control parts 713b themselves, that is, the flow passage 712 (direction control part 713b) is swung in the left-right direction as a whole to a desired direction, thereby controlling the discharge direction of the auxiliary air Y. Therefore, although the flow passage 712 appears to be gradually enlarged from the air source 711 toward the discharge port in Figures 27 and 28, the shape of the flow passage 712 in this embodiment is a shape intended to increase the left-right swing width of the auxiliary air Y, and the flow passage 712 is not formed to be gradually enlarged inside.

[0144] In this embodiment, the direction control unit 713 may be formed only with direction control unit 713c which is movable in the up, down, left and right directions, or only with direction control unit 713b which is movable in the left and right directions, but it is preferable that it is composed of direction control unit 713b and direction control unit 713c.

[0145] Similarly to the eighth embodiment, the direction control unit 713 is basically electrically operable, but may be operated automatically or manually.

[0146] 10. Tenth embodiment (discharge control system 500)

[0147] (1) Configuration example of discharge control system 500

[0148] 29 is a block diagram showing an example of the concept of the discharge control system 500. In this embodiment, the discharge control 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, an input unit 506, and an auxiliary air presentation unit 507. In addition, the discharge control system 500 may include other units, etc., as necessary. Each component of the discharge control system 500 will be described below.

[0149] (2) Information acquisition unit 501

[0150] 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.

[0151] 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.

[0152] Specific examples of the information acquisition unit 501 include, for example, as shown in FIG. 29, an environmental sensor, a vital sensor, a camera, a brightness sensor, and also, although not shown, an infrared sensor, an odor sensor, a gas sensor, etc., or one or more of these may be used in combination.

[0153] The information obtainable from the various sensors described above is not particularly limited, and for example, the environmental sensor obtains temperature, humidity, air pressure, amount of ultraviolet light exposure, etc.; the vital sensor obtains vital signs such as pulse, blood pressure, respiration, and body temperature, as well as brain pressure, number of blinks, amount of bleeding, amount of sweat (including amount of sweat during sleep), amount of tears secreted, level of consciousness, amount of excrement, etc.; the camera obtains race, sex, age, whether or not an object is present, position of the object, number of objects, height of the object, position of specific parts of the object (e.g., face, nose, hands, feet, back, etc.); and the brightness sensor obtains information such as race, sex, age, whether or not an object is present, position of the object, number of objects, height of the object, position of specific parts of the object (e.g., face, nose, hands, feet, back, etc.). , a brightness sensor that measures the amount of indoor lighting, the amount of lighting at the entrance, etc.; an infrared sensor measures changes in outside temperature, room temperature, radiant temperature, perceived temperature, human position, and the operating status of various devices (for example, televisions, air conditioners, electric fans, circulators, air purifiers, humidifiers, commercial air conditioning systems, automatic doors, automatic toilet lids, non-contact thermometers, etc.); an odor sensor measures odors, etc.; a gas sensor measures 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 corresponding to a specific target with higher accuracy. Each sensor may measure by directly contacting a specific target, or may measure without contact. Recent technology has also included non-contact types of vital sensors, and this technology can also use such types of vital sensors.

[0154] 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.

[0155] (3) Control unit 502

[0156] The control unit 502 is a part that determines the ejection conditions of the odor-containing air K 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.

[0157] 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.

[0158] The "scent" here is the same as that described above, and therefore will not be described here. The ejection conditions determined by the control unit 502 may be, for example, any one or more selected from the group consisting of the type of scent, ejection direction, ejection distance, ejection amount, ejection speed, ejection location, and diffusion range, but are not particularly limited in the present technology. In addition, when there are multiple scent generating cartridges 1, the control unit 502 may determine the same ejection conditions for each scent generating cartridge 1, or may determine the ejection conditions for each scent generating cartridge 1.

[0159] 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 ejection conditions based on the results of the evaluation.

[0160] In this case, the control unit 502 can set a desired environment based on the result of the evaluation. The term "setting" here includes both the concepts of manual and automatic, 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 ejection conditions based on the result of the evaluation. Also, when it is desired for the specific subject to create an environment in which he or she can concentrate, the control unit 502 can set the desired environment by changing the ejection conditions based on an instruction from the specific subject and the result of the evaluation.

[0161] The control unit 502 may be capable of communicating with, for example, the information acquisition unit 501, the odor generating cartridge 1, the odor control unit 532, the odor presentation unit 503, and the discharge control unit 71 via a wired or wireless (for example, Wi-Fi, Bluetooth, etc.) network. The control unit 502 may also be capable of communicating with other components of the discharge control system 500 via a wired or wireless network.

[0162] Examples of the control unit 502 include, but are not limited to, applications stored in a smartphone, a tablet terminal, a wearable terminal, a personal computer, etc. Examples of the application include a native application, a Web application, a hybrid application, an embedded application, etc.

[0163] (4) Odor presentation unit 503

[0164] The odor presentation unit 503 is a part that emits an odor based on the emission conditions determined by the control unit 502. A specific example of the odor presentation unit 503 includes, for example, an odor generating cartridge 1 and an odor control unit 532.

[0165] Fig. 30 is a perspective view showing an example of an embodiment of the odor presentation unit 503. Fig. 31 is a six-sided view showing the embodiment shown in Fig. 30, 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. 32 is a perspective view showing an example of the structure inside the housing of the odor presentation unit 503.

[0166] 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 components as necessary. In Figures 30 and 31, the odor generating cartridge 1 and the odor control unit 532 are present within the housing of the odor presentation unit 503, as shown in Figure 32.

[0167] In this embodiment, the odor presentation unit 503 is substantially rectangular tubular as shown in Figures 30 and 31, 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, substantially polygonal pyramidal such as substantially triangular or substantially rectangular cross section (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 formed by combining substantially cylindrical shapes with different diameters.

[0168] In the odor presentation unit 503, odor-containing air K is discharged from an outlet 533. That is, the outlet 533 is a portion where an odor is presented as a result of the odor control unit 532 operating in accordance with the discharge conditions instructed by the control unit 502. The outlet 533 is provided in a part of the housing of the odor presentation unit 503, for example, at the position indicated by E in FIG.

[0169] In addition, if the odor presentation conditions determined by the control unit 502 cannot be realized by the odor presentation unit 503 alone, the control unit 502 can also instruct the auxiliary air presentation unit 507 described later on the odor presentation conditions, thereby realizing the desired emission conditions. Each part of the odor presentation unit 503 will be described below.

[0170] [Odor generating cartridge 1] The odor generating cartridge 1 is similar to that described in "(2) Odor generating cartridge 1" of "1. First embodiment (emission control mechanism 7)", and therefore will not be described here.

[0171] [Modification of odor generating cartridge 1] Modified examples of the odor generating cartridge 1 will now be described. Figure 33 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 34 is a perspective view of the embodiment shown in Figure 33, and Figure 35 is a cross-sectional view along line PP of the embodiment shown in Figure 33. Odor generating cartridge 1 of this modified example at least comprises odor retaining section 101, ventilation section 102, and connecting section 103.

[0172] As shown in Fig. 35, 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.

[0173] 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 "(2) Odor-generating cartridge 1" of "1. First embodiment (emission control mechanism 7)", so a description thereof will be omitted here. The scent retained in the impregnating material 20 is also not particularly limited, and is similar to those described in "(2) Odor-generating cartridge 1" of "1. First embodiment (emission control mechanism 7)", so a description thereof will be omitted here.

[0174] The container part 21 preferably has a two-layer structure, and in this embodiment, as shown in FIG. 35, 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 from 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 from metal foil, or the inner wall may be metal-plated.

[0175] The ventilation section 102 includes an openable / closable ventilation opening 30. In this embodiment, the ventilation section 102 is 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. 35, but this is not particularly limited in the present technology, and the ventilation section 102 may be composed of a single section, or may be divided into three or more sections. That is, in this embodiment, the ventilation opening 30 includes 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, as shown in FIG. 35. 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 as long as it is possible to open and close the two ventilation openings 30 (30a, 30b), and can be freely designed. Specifically, as shown in FIG. 36 described later, an opening and closing mechanism may be provided that is made up of a sealing lid 1021 (1021a, 1021b), a shaft 1022, and a spring 1023 (1023a, 1023b).

[0176] In this embodiment, the ventilation section 102 preferably has a two-layer structure, and in this embodiment, as shown in Figure 35, 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.

[0177] 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) consist of 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, as shown in FIG. 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.

[0178] 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.

[0179] 36 is a cross-sectional view showing how an odor is discharged from the odor generating cartridge 1. 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 is sent to the odor, where it is scented as the airflow passes near the impregnating material 20, and odor-containing air K is released. In this state, the released odor-containing air K flows into the connecting section 103 through the other connecting opening 40b, and is released to the outside.

[0180] 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. 36. Note that FIG. 36 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.

[0181] 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 the odor-containing air K is released. This odor-containing air K flows again into the connecting part 103 through the second connecting opening 40b provided in the lid part 22.

[0182] 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.

[0183] To drive the pusher X, for example, 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, as shown in FIG. 32. A wiring capable of supplying power is connected to the driving source X2, and power may be supplied from a battery or other cell (including a storage battery) via the wiring, or from a power source. The pusher X can move in the extension direction within the housing of the presentation unit 503 by the expansion and contraction of the shape memory alloy SMA. For example, the shape memory alloy SMA is folded back into a U shape at the SMA sliding part X1 provided near the tip of the pusher X, 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 a plunger, such as a motor, a solenoid, a linear slide type, a pneumatic (air pump type), or a small electromagnet.

[0184] [Odor control unit 532] The odor control unit 532 is a part that controls the odor presentation unit 503 based on instructions from the control unit 502. The installation location of the odor control unit 532 is not particularly limited, and may be installed, for example, inside the housing of the unit 503 as shown in FIG.

[0185] The odor control unit 532 controls the odor presentation unit 503 based on the ejection conditions determined by the control unit 502 so that the ejection conditions are realized. Specifically, the ejection conditions can be realized by, for example, replacing the cartridge 1, mixing the odor-containing air K from two or more cartridges 1 at a desired ratio, controlling the ejection amount and ejection speed of the odor-containing air K, the concentration of the fragrance in the cartridge 1 used, the number of ejections of the odor-containing air K, the ejection time, and the ejection stop time, or by controlling one or more of these in combination. In addition, the odor control unit 532 can also contribute to the realization of the ejection conditions by controlling the pump direct drive mechanism 6, the deodorizing mechanism 51, and the like attached to the odor generating cartridge 1 as necessary.

[0186] Furthermore, 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, two or more odor presentation units 503 can be placed side by side by a joining mechanism (e.g., engagement using a concave-convex shape; engagement using claws, pins, hooks, clamps, etc.; engagement using an adhesive with sufficient adhesiveness to allow removal and attachment; sliding engagement, etc.) provided on the side of the housing of the odor presentation unit 503.

[0187] (5) Storage section 504

[0188] The storage unit 504 is a part that 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 inside the housing of the control unit 502, or may be connected to an external control device or the like 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 cloud via the network. In consideration of the personal information of users, some information may be made viewable only by those who have viewing authority.

[0189] Furthermore, the storage unit 504 may perform machine learning using the AI ​​5041 based on all stored information. As a result, it is possible to present an odor corresponding to a specific target with higher accuracy to the specific target. Furthermore, the machine learning may be performed on the cloud, in which case each user can share the results of the machine learning present on the cloud via a network.

[0190] When the discharge control system 500 has a storage unit 504, the control unit 502 may determine the discharge conditions based on information stored in the storage unit 504. Specifically, for example, a history of discharge conditions set for a user in the past, discharge conditions evaluated by the user in the past, reactions shown by the user in the past (for example, vital data, etc.), discharge conditions accumulated on the cloud, discharge conditions based on knowledge obtained by machine learning, or information combining one or more of these, may be mentioned, but is not particularly limited in the present technology.

[0191] Further, the storage unit 504 may be located within the housing of the control unit 502, but various information may be stored using one or more types of external storage devices.

[0192] (6) Output unit 505

[0193] 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.

[0194] Also, the output unit 505 may be located inside the housing of the control unit 502, but may output various information using one or more types of external output devices, etc. Furthermore, 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.

[0195] (7) Input unit 506

[0196] The input unit 506 is a unit where a user inputs information to each unit of the discharge control mechanism 7. Specifically, for example, a keyboard, a smartphone, a tablet terminal, a wearable terminal, a voice input device, etc. can be mentioned, but the present technology is not particularly limited thereto. In addition, the user may input the previously prepared information via the input unit 506.

[0197] In addition, the input unit 506 may be a keyboard or the like attached to the housing of the control unit 502, or various information may be input using one or more types of external input devices (i.e., a smartphone, a tablet terminal, a wearable terminal, a voice input device, etc.) connected wirelessly or via a wire.

[0198] (8) Auxiliary wind presentation section 507

[0199] The auxiliary airflow presentation unit 507 presents an auxiliary airflow Y that assists the blowing of the odor-containing air K emitted from the odor presentation unit 503. A specific example of the auxiliary airflow presentation unit 507 includes, for example, an airflow source 711 and an emission control unit 71. That is, the auxiliary airflow presentation unit 507 is similar to that described in the emission control unit 71 of "1. First embodiment (emission control mechanism 7)" to "9. Ninth embodiment (emission control mechanism 7)", and therefore a description thereof will be omitted here.

[0200] The auxiliary wind presentation unit 507 may be integrated with the smell presentation unit 503, or may be provided outside the smell presentation unit 503. 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 auxiliary wind presentation unit 507, and the smell presentation unit 503 may be attached to a part of the housing of these devices as necessary.

[0201] Furthermore, the auxiliary wind Y may be generated using one or more types of auxiliary wind generating units 507 that are independently developed, as necessary.

[0202] (9)Other

[0203] The discharge control 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 that the vital signs of a specific target have significantly decreased. The warning unit may be connected to other parts of the discharge control system 500 by wire or wirelessly. In this case, the discharge control system 500 can be used to perform first aid such as emitting a strong odor or spraying a gas with a pharmacological effect on the specific target whose vital signs have decreased. The warning unit may automatically output current information on the specific target to the user's family, medical institutions, emergency transport facilities, etc.

[0204] Furthermore, the discharge control system 500 may include a reading unit that reads information from an information display unit included in the odor generating cartridge 1, if necessary. Examples of the reading unit include a camera, a barcode reader, etc. 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.

[0205] 11. Application Examples of Discharge Control Mechanism 7 and Discharge Control System 500

[0206] (1) Examples of application

[0207] The discharge control mechanism 7 and the discharge control system 500 according to the present technology can be applied in a wide range of fields, as described below.

[0208] Specifically, it is used, for example, in olfactory tests, olfactory training (including olfactory stimulation therapy), etc. The olfactory training here is broadly interpreted and includes practice for odor judge exams, sommelier exams, aromatherapy certification, etc. It may also be used for odor simulation when developing medicines, quasi-drugs, cosmetics, food and beverages, etc. Furthermore, it may be installed in relaxation products such as head-mounted displays, neck pillows, massage chairs, eye pillows, eye massagers, head massagers, hand massagers, and foot massagers, and in vehicles such as automobiles, buses, trains, ships, and airplanes.

[0209] In addition, it may be used in products for attracting customers, such as vending machines, signs, digital signage, robots, etc. In addition, it may contribute to the presentation of scents corresponding to exhibits, plants and animals in art galleries, museums, libraries, zoos, botanical gardens, etc., and may be used as part of the production in concert halls, opera houses, live music venues, stages, movie theaters, amusement facilities, etc.

[0210] In addition, the present invention can be applied to, for example, calming the mood, elevating the mood, making it easier to fall asleep, sleep, and wake up, generating odors that pests and vermin dislike, and generating odors in elevators, stores, offices, etc. according to conditions such as time, scene, and population density. Specific targets may be classified into ordinary people, athletes, pregnant women, hospitalized patients, babies, pet animals, etc., and an appropriate odor may be generated for each target. In this case, the specific target may be one or more, and the odor may be adjusted by the discharge control system 500 for each facility, such as a gym where athletes gather, an obstetrician-gynecologist's office where pregnant women gather, a hospital facility where hospitalized patients gather, and a veterinary clinic where pet animals gather.

[0211] (2) Specific examples

[0212] A specific example in which the discharge control mechanism 7 and the discharge control system 500 according to the present technology are used will be described below.

[0213] (2-1) When used for the purpose of entertainment at amusement facilities

[0214] In this specific example, it is assumed that the technology is used to produce an event held in an amusement facility. Specifically, for example, a sensor recognizes a person's back, and while providing an odor from the front of the person, the moment the person turns around, a different odor is provided, producing a more natural and realistic event. While there are many conventional devices that provide odors from the front of a person, this technology is extremely useful because it can provide odors quietly or suddenly from behind. The provision of odors from behind will be explained in "(2-4) Others" below.

[0215] More specifically, if the goal is to create a sense of elation (for example, an emotionally charged scene at a live concert), spicy smells like spices or refreshing peppermint smells are provided from the left and right to amplify the sense of elation. If the goal is to create a sense of calm (for example, an emotional scene at a movie theater), soothing smells like lavender or wild grass are provided from the left and right to amplify the sense of calm. Furthermore, if the goal is to create a sense of fear (for example, a scary scene in a haunted house), a fishy smell like river, willow, and chrysanthemum flowers are emitted from the left, and a fishy smell like blood is emitted from the right, and then a ghost doll appears from the right.

[0216] In addition, the AI5041 is used to collect and analyze the results of each sensor, and to create a list of optimal scents based on information such as race, gender, age, etc. In addition, for example, an environmental sensor can be used to check seasonal scents and preferences, allowing the system to provide more optimal scents.

[0217] (2-2) Presenting odors in accordance with human movements

[0218] In this specific example, it is assumed that an odor is provided in accordance with human movement. Specifically, for example, a human movement is sensed and an odor is provided to a specific target. This contributes to revitalizing people's lives and increasing their desire to buy, depending on the location, season, and weather. In this specific example, the flow path 712 and the direction control unit 713 in the discharge control mechanism 7 may also be used to provide the odor.

[0219] Specific examples will be described in detail below, divided into different scenarios. [Scene: At home] The scent presentation unit 503 and auxiliary air presentation unit 507, or the discharge control mechanism 7 can be installed in the entrance or living room of one's home, and scents such as a fresh lemon scent can be provided to wake one up before commuting to work or school, or a soothing lavender scent can be provided to calm one down when returning home. [Scene: Station] By installing the scent presenter 503 and the auxiliary wind presenter 507, or the discharge control mechanism 7, on the pillar or ceiling near the ticket gate, when passing through the ticket gate at the station, the scent of the local specialty is presented, which can contribute to increasing the desire to purchase souvenirs, meals, etc. around the famous spots. In this case, the scent may be changed depending on the time of day.

[0220] [Scene: Roads (including expressways)] By installing the scent presentation unit 503 and the auxiliary wind presentation unit 507, or the discharge control mechanism 7, in the vehicle, the scent of local specialty products can be provided when traveling to other cities, towns, villages, or prefectures, which can stimulate conversation with passengers and prevent drowsy driving. It also contributes to increasing motivation to travel to famous places and increasing motivation to purchase souvenirs, meals, etc. at roadside stations and service areas.

[0221] [Scene: Shop] The scent presenting unit 503 and auxiliary air presenting unit 507, or the discharge control mechanism 7, can be installed on the pillars or entrance beams of a shop to present the scents of sweets, perfume, shampoo, cosmetics, etc. when attracting customers, thereby attracting customers to the store. In this case, the scents may be presented after the race, sex, age, etc. of people passing by the store are obtained by the information obtaining unit 501. [Scene: Event venue] The scent presenting unit 503 and auxiliary wind presenting unit 507, or the discharge control mechanism 7, are arranged around the speaker, and during the live performance, depending on the type of music, for example, a scent that gives an uplifting feeling for rock music and a scent that gives a calming feeling for ballad music, can be presented, helping each participant to become more immersed in the live performance. In this case, the race, sex, age, etc. of the participants are acquired by the information acquiring unit 501, and the scent can be provided to a large number of participants over a wide diffusion range, or a specific scent can be provided to some participants at the live performance venue by using directional wind.

[0222] In addition, the AI ​​5041 is used to collect and analyze the results of each sensor, and to list the most suitable odors based on information such as race, sex, age, etc. In addition, for example, the odors can be presented in conjunction with the output unit 505 (i.e., in conjunction with an image displayed on a monitor (including digital signage) or music from a speaker).

[0223] (2-3) When installing on a seat or equipment with an air discharge function

[0224] In this specific example, it is assumed that the odor presenting unit 503 and the auxiliary air presenting unit 507, or the discharge control mechanism 7 are attached to a seat or a device having an air discharge function.

[0225] Conventionally, seats or devices with air emission functions have often not been equipped with devices that present odors. In this specific example, by attaching at least an odor presentation unit 503 including the odor generating cartridge and an auxiliary air presentation unit 507 including the emission control unit 71, or an emission control mechanism 7 to these items either externally or internally, an appropriate odor suited to the scene can be presented, thereby providing the user with the effect of increasing their concentration and waking them up or relaxing them while working, engaging in hobbies, etc.

[0226] Note that the "seat" referred to here is a place to sit and the equipment associated with that place, and is generally referred to as a chair, bench, etc. Types of seats include not only seats provided in moving objects such as vehicle seats and airplane seats, but also seats provided in various facilities such as concert halls, opera houses, live music venues, stages, movie theaters, and amusement facilities. Furthermore, while seats are basically single-seaters, examples include pair seats for two people, and chairs and benches that can seat more than two people.

[0227] In the present technology, among these, vehicle seats are particularly preferred, and vehicle seats for one person such as a driver's seat or a passenger seat are more preferred. Note that the term "vehicle" as used herein includes not only passenger automobiles (hereinafter also referred to as "passenger cars"), but also automobiles such as buses, trucks, three-wheeled motor vehicles, motorcycles, and motorized vehicles, as well as railway vehicles such as passenger cars, locomotives, and freight cars.

[0228] In addition, examples of the "device having an air discharge function" herein include air conditioners, electric fans, circulators, air purifiers, humidifiers, and commercial air conditioning systems, but the present technology is not particularly limited thereto.

[0229] Here, as described above, when providing an odor, it is necessary to optimize the discharge conditions of the gas containing the odor-containing air K, but various factors are involved in determining the discharge conditions. In particular, factors involved in this specific example include, for example, the distance to the target, the gender of the target, the physique of the target, the hair length of the target, the clothing of the target, the sitting height of the target, the distance to the tip of the target's nose, the discharge amount and discharge speed to the target, as well as temperature, humidity, air pressure, etc. In order to determine the discharge conditions taking these factors into consideration, for example, the discharge control system 500 according to the present technology can be used.

[0230] When attached to a seat, the location of attachment is not particularly limited, and may be, for example, the seat, the backrest portion attached to the seat at the rear of the seat, the left and right armrest portions arranged on the left and right sides of the seat, the headrest, the left and right wing portions protruding forward near the headrest, etc., or it may be attached to two or more of these locations.

[0231] The case of attaching to a device with an air discharge function is not particularly limited, and examples include attaching to the vicinity of the air discharge part of the device using a string or wire, incorporating the scent presentation part 503 and the auxiliary air presentation part 507 or the discharge control mechanism 7 into the device, attaching to another item near the device with an air discharge function (for example, a drink holder attached to a passenger vehicle when the air conditioner of the vehicle is the device with an air discharge function), etc. Alternatively, it may be attached to two or more of these locations.

[0232] [When installing in a passenger car air conditioner] The following description will be given assuming a case where the device is installed in an air conditioner of a passenger vehicle as a specific example of the case where the device is installed in a device having an air discharge function.

[0233] When installed in an air conditioner in a passenger vehicle, the information acquisition unit 501 recognizes the position of the target's face and lets the target know the timing for delivering the scent by displaying a message on a car navigation system, smartphone, etc., turning on a lamp, or giving a voice notification. By then facing the target toward the air conditioner's outlet only at that timing, the scent can be presented to the target by utilizing the air conditioner's wind.

[0234] In this case, the odor presenting unit 503 and the auxiliary air presenting unit 507, or the emission control mechanism 7, may deliver the odor-containing air K to the air conditioner outlet. In addition, if the subject feels uncomfortable when air is blown onto the face, this can be resolved by shortening the minimum emission amount required to transport the odor-containing air K or the emission time of the odor-containing air K.

[0235] FIG. 37 is a block diagram showing the functions of each part when the device is installed in an air conditioner of a passenger vehicle. In FIG. 37, a part of the discharge control mechanism 7 and the discharge control system 500 are omitted. In the block diagram shown in FIG. 37, an in-vehicle camera, a temperature sensor, and an odor generating cartridge reader are used as the information acquisition unit 501, and from these, the position of the target's face, temperature detection, and type of the cartridge 1 are recognized. Then, the control unit 502 (not shown) or the condition control unit 72 controls the air conditioner to change the direction of the outlet to face in the case of wind direction, to change the air volume to blow weak air, and to operate for a few seconds in the case of operation time. In addition, the control unit 503 including at least the odor generating cartridge and the auxiliary airflow presentation unit 507 including the discharge control unit 71, or the discharge control mechanism 7, controls to set the discharge time to a few seconds in the case of operation time, and to select the type of the odor generating cartridge 1.

[0236] In addition, various other types of control are possible, such as controlling the intensity of the odor depending on the air conditioner's airflow, or controlling the air conditioner's flow speed and airflow depending on the distance from the air conditioner to the face, but this technology is not necessarily limited to the above.

[0237] [When mounting on a seat] In the following, as a specific example of installation on a seat, a description will be given assuming installation on a one-seater seat having at least a seat portion and a backrest portion attached to the seat portion.

[0238] Fig. 38 is an explanatory diagram explaining the state when a man T1 sits in the seat, and Fig. 39 is an explanatory diagram explaining the state when a woman T2 sits in the seat. In Figs. 38 and 39, the seat has a seat portion A1, a backrest portion A2, and a headrest A3. As described above, when the odor presentation unit 503 and the auxiliary wind presentation unit 507, or the discharge control mechanism 7 are attached to the seat (note that in Figs. 38 and 39, the discharge control mechanism 7 is attached), the attachment location is not particularly limited, but it is preferable that it is a location where gas containing odor-containing air K can be blown toward at least a part of the area from the head to the waist (preferably from the shoulders to the waist) of a specific target.

[0239] Specifically, the seat back A2 is preferably attached to a part of the backrest A2 on the headrest A3 side, near the tip of the backrest A2 on the headrest A3 side, or between the backrest A2 and the headrest A3, and it is particularly preferably attached to the tip of the backrest A2 on the headrest A3 side as shown in Figures 38 and 39. Although not shown, if the seat has left and right wing parts protruding forward near the headrest, the seat back A2 may be attached to either the left or right wing part.

[0240] Comparing Figures 38 and 39, it can be seen that the seated height differs depending on gender when seated. If the seated height differs, the arrival angle of the gas containing the odor-containing air K differs. Therefore, depending on the arrival angle, a problem occurs in that a particular target cannot sense an odor at all. Therefore, when considering how to deal with differences in seated height using the same discharge control mechanism 7, the inventors of the present application found that this can be done by changing the discharge range of the gas using the direction control unit 713 depending on the target.

[0241] That is, the inventors of the present application measured the distance F in FIG. 38 and the distance F in FIG. 39, and based on this, they obtained the detection angles of the gas containing the odor-containing air K for the male T1 and the female T2. FIG. 40 is a diagram showing the detection angle for the male T1, and FIG. 41 is a diagram showing the detection angle for the female T2. The dashed line is a straight line passing through the center part of the discharge control mechanism 7, and each detection angle is described in FIG. 40 and FIG. 41 with this straight line set as 0°. As shown in FIG. 40, it was found that the detection angle was 5° to 40° for the male T1, and -15° to 35° for the female T2. From these results, it was also found that the angle range of -15° to 40° is appropriate as the range in which the gas containing the odor-containing air K can be delivered to both the male T1 and the female T2, and has a width of about 60°.

[0242] Therefore, for example, by using a flap-type direction control unit 713 or a discharge control mechanism 7 that is capable of controlling the direction by integrating the flow passage 712 and the air source 711, the angle of the discharge direction of the auxiliary air Y can be controlled so that the gas containing the odor-containing air K is discharged within a desired discharge range. At this time, the information acquisition unit 501 may acquire the gender, and the information may be used to determine the discharge range.

[0243] Fig. 42 is an explanatory diagram for explaining a suitable angle of a direction control unit 713 provided at the discharge port. Specifically, the direction control unit 713 shown in Fig. 42 is a louver having a structure in which a flap moves up, down, left, and right, and by orienting the louver 10° to 20° inward (i.e., toward the target T shown in Fig. 42A), the gas containing the odor-containing air K can be delivered more efficiently. Note that the discharge control mechanism 7 shown in Fig. 42B is provided with a temporary assembly member 714 for temporary assembly to a structure inside the seat, but the present technology is not limited to the structure shown in Fig. 42B, and in some cases, the temporary assembly member 714 may not be provided.

[0244] FIG. 43 is an explanatory diagram for explaining the X-direction, Y-direction, and Z-direction of the seat. In this specific example, the front-rear direction when viewing the seat from the front is defined as the X-direction (roll), the left-right direction is defined as the Y-direction (pitch), and the height direction is defined as the Z-direction (yaw). FIG. 44 is a diagram showing the optimal tilt angles of the discharge control mechanism 7 in the X-direction, Y-direction, and Z-direction when the discharge control mechanism 7 is attached to the seat. That is, by tilting the discharge control mechanism 7 to 25.5° in the X-direction (see B in FIG. 44), 33° in the Y-direction (see C in FIG. 44), and 17° in the Z-direction (see A in FIG. 44), it is possible to efficiently deliver the gas containing the odor-containing air K to the subject seated in the seat. Note that all of these numerical values ​​may actually have an error of about ±10°.

[0245] In the above example, particular attention was paid to the gender of the person and the distance from the seat to the tip of the person's nose to derive suitable ejection conditions, but other information acquired by the information acquisition unit 501 and / or information prepared in advance that is relevant when attaching to a seat includes, for example, the person's sitting height, the length of the person's hair, the width of the seat or backrest of the seat, the position of the person's lower back when seated in the seat, the angle between the seat and backrest of the seat, and the position of the headrest attached to the seat, or a combination of one or more of these.

[0246] Specifically, for example, in the case of long hair, the hair itself becomes a wall of gas, causing a problem that the odor does not reach the user. To address such a problem, the discharge conditions are changed so that the gas containing the odor-containing air K moves toward the inside of the user, thereby compensating for the difference in hairstyle. That is, in this case, the problem can be solved by controlling the discharge direction and discharge range. Also, if necessary, measures such as changing the shape of the direction control unit 713 may be taken.

[0247] (2-4)Other

[0248] Below, matters to be considered other than the specific examples described above will be described.

[0249] Considering that the odor presentation unit 503 and the auxiliary air presentation unit 507, or the discharge control mechanism 7, will be attached to the seat as described above, there is a need to place them behind a specific target, if possible.

[0250] 45 and 46 are explanatory diagrams for explaining the case of presenting an odor from the rear side. As shown in Fig. 45 and Fig. 46, even if gas containing odor-containing air K is discharged from the rear toward a specific target T, it does not reach the nose of the target T.

[0251] Therefore, in the specific example shown in Figure 45, by using a flap-type directional control unit 713 and an emission control mechanism 7 that integrates the flow path 712 and the air source 711 and allows for direction control, when a straight line passing through the center of the emission control mechanism 7 is set to 0°, the angle of the emission direction of the auxiliary air Y in the left-right direction can be controlled within a range of -30° to 30°, and gas containing odor-containing air K can be controlled to be emitted within the desired emission range (for example, by moving the direction control unit 713 by 60°).

[0252] In addition, in the specific example shown in Figure 46, by offsetting the outlets of the two flow paths 712 to the left and right by approximately 30 mm from the center of the back surface (preferably within 20 mm from the center of the discharge portion 14), it is possible to entrain the odor-containing air K discharged from the discharge portion 14 into the auxiliary air Y flowing through the flow path 712, and to cause the gas containing the odor-containing air K to flow around the nose of a specific target T.

[0253] In addition, the placement of the odor presentation unit 503 and the auxiliary wind presentation unit 507, or the emission control mechanism 7, was also considered in cases where it is desired to place them around the shoulder of a specific subject, and where it is desired to attach the odor presentation unit 503 and the auxiliary wind presentation unit 507, and the emission control mechanism 7 to a wearable device worn by a specific subject.

[0254] Fig. 47 is an explanatory diagram for explaining the case where an odor is presented from around the shoulder of a specific target, or where the device is attached to a wearable device worn by a specific target. As shown in Fig. 47, even if gas containing odor-containing air K is discharged from the shoulder toward a specific target T, the gas passes past the nose of the target T, causing a problem that the target T cannot sense the odor.

[0255] 47, a gas containing odor-containing air K is bent using wind from the front or side to provide an odor to a specific target T. Examples of wind that can be used from the front or side include wind generated from an air conditioner from the driver's seat or passenger seat when inside a car, and wind generated from a conventionally known blower such as an air conditioner or electric fan when indoors, but are not particularly limited in the present technology.

[0256] Furthermore, when attaching to a wearable device, a particular problem occurs when a specific target T is moving. As shown in Figure 47, when walking, for example, if gas containing odor-containing air K is discharged directly upward due to wind from the front, the odor passes behind the target, so by discharging the gas diagonally in front of the target, the odor can be presented to the target's nose. In this case, the angle at which the gas is discharged can be determined taking into account the walking speed of the target T, etc.

[0257] In addition, since it becomes even more difficult to present the scent to the subject's nose if there is a headwind, it is possible to control the wind by grasping the direction of the wind and blowing a volume of wind that can counter the headwind. Therefore, when walking, it is also important to grasp the direction in which the wind is blowing with respect to a specific subject T.

[0258] (2-5) Example of operation flow of the discharge control system 500 when installed on a seat

[0259] FIG. 48 is a flowchart showing an example of the operation of the discharge control system 500 when the odor presenting unit 503 and the auxiliary air presenting unit 507, or the discharge control mechanism 7 is attached to the seat. First, the odor presentation unit 503 and the auxiliary wind presentation unit 507, or the discharge control mechanism 7 are attached to a suitable position on the seat (S101). Suitable positions on the seat include, for example, those described in the above-mentioned "When Attached to a Seat". Next, the information acquisition unit 501 performs sensing to acquire target information (S102). The information acquired here includes factors that are particularly relevant when attached to a seat. Examples of such factors include those described in the above-mentioned "When Attached to a Seat". As described above, the information here may include information prepared in advance. For example, in the operation flow shown in FIG. 47, at least the distance from the seat to the tip of a person's nose is sensed. Next, based on the acquired information, the control unit 502 determines the discharge conditions for the odor-containing air K (S103).

[0260] Here, the control unit 502 can estimate the state of the person from the information acquired by the information acquisition unit 501, and present an odor based on the estimation. For example, if the estimated state of the person is a working mode, an odor that tightens the mood according to the amount of brain activity can be presented, or if the person has been in the room for a long time, a different odor can be emitted to change the mood. Also, if the estimated state of the person is a relaxation mode, an odor that calms the person can be presented if the person seems unsettled, or an odor suitable for sleep can be emitted when it is detected that the person has gone to sleep.

[0261] Although not shown, it is also possible for the subject to select a mode by himself / herself in relation to the control unit 502 and to present an odor while also referring to information from the information acquisition unit 501. 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 the AI ​​5041.

[0262] Next, the presentation unit 503 discharges the odor-containing air K and auxiliary air Y based on the determined discharge conditions (S104). Next, after a certain time has elapsed since the odor was presented, the information acquisition unit 501 performs sensing again to acquire information on the subject (S105). Based on the information acquired here, the control unit 502 evaluates whether the desired discharge conditions have been achieved (S106). The subject may input the evaluation via the input unit 506 himself / herself.

[0263] If it is determined that the desired discharge conditions have been achieved, the control unit 502 or the subject determines whether or not to continue presenting the odor (S107). Here, the control unit 502 may refer to information such as the subject's vital signs acquired using the information acquisition unit 501 when making this determination.
