[Modes for carrying out the invention]

[0011] The following describes preferred embodiments for implementing this technology with reference to the drawings. The embodiments described below are examples of typical embodiments of this technology, and any combination of these embodiments is possible. Furthermore, this does not mean that the scope of this technology will be narrowed. The explanation will proceed in the following order. 1. First Embodiment (1) Example of the configuration of a fragrance dispensing device (2) Example of operation of the fragrance dispensing device 2. Second Embodiment (1) Example of the configuration of a fragrance dispensing device (2) Example of operation of the fragrance dispensing device 1 (3) Example of operation of the fragrance dispensing device 2 (4) Example of operation of the fragrance dispensing device 3 (5) Example of operation of the fragrance dispensing device 4 (6) Example of operation of the fragrance dispensing device 5 (7) Example of operation of the fragrance dispensing device 6 (8) Example of operation of the fragrance dispensing device 7

[0012] 1. First Embodiment (1) Configuration Example of Scent Providing Device Referring to FIGS. 1 and 2, a configuration example of a scent providing device 100 according to the first embodiment of the present technology will be described. FIG. 1 is a schematic configuration diagram showing a configuration example of the scent providing device 100 according to the present embodiment. FIG. 2 is a partial cross-sectional view showing a configuration example of the scent providing device 100.

[0013] As shown in FIG. 1, a scent providing device 100 such as an olfactory display includes a fragrance holding unit 101, an air flow control unit 102 connected to the fragrance holding unit 101, and a temperature control unit 104 connected to the fragrance holding unit 101 and the air flow control unit 102.

[0014] The fragrance holding unit 101 has, for example, a fragrance holding member that holds a fragrance, which is a substance that serves as the source of the scent provided to the user.

[0015] The air flow control unit 102 has an air flow control section 103. The air flow control section 103 includes an opening 111 that discharges or inhales a fragrance-containing air flow Fk containing the scent to the outside, a flap 112 disposed at the tip of the opening 111 that varies the flow of the fragrance-containing air flow Fk, and an air flow passage section 113 through which a control air flow Fu that controls properties such as the direction and / or intensity of the fragrance-containing air flow Fk flows. As shown in FIG. 2, inside the air flow control unit 102, there is an air flow adjustment fan 114 that generates an adjustment air flow Fh for stirring or exhausting the air flow. The air flow control unit 102 is preferably disposed near the opening 111. The air flow control unit 102 may be integrated with a thermoelectric coil, a Peltier element, a water absorber (vaporization heat cooling), etc.

[0016] The airflow control unit 102 can generate a controlled airflow Fu that accelerates, decelerates, and / or diffuses the fragrance-containing airflow Fk. Diffusion includes blowing away the fragrance to reduce its concentration in the airflow and spreading the fragrance-containing airflow into the surroundings. The airflow control unit 102 can also generate a controlled airflow Fu that obstructs the flow of the fragrance-containing airflow Fk. The airflow control unit 102 can also control the intensity of the fragrance-containing airflow Fk by mixing multiple controlled airflows Fu. The airflow control unit 102 can also draw in and exhaust ambient air near the opening.

[0017] The temperature control unit 104 releases or draws in warm or cold air depending on the fragrance contained in the fragrance-containing airflow Fk. The temperature control unit can also adjust the humidity of the fragrance-containing airflow Fk.

[0018] (2) Example of operation of the fragrance dispensing device Next, with reference to Figures 1 to 3, an example of odor detection operation by the fragrance dispensing device 100 will be described. Figure 3 is a schematic configuration diagram illustrating an example of operation of the fragrance dispensing device 100. Note that the operation procedure shown below can be performed in any order.

[0019] As an example, in the first step, the fragrance to be provided to the user is held in a fragrance holding member, and the fragrance holding member holding the fragrance is incorporated into the fragrance holding unit 101.

[0020] In the second step, as shown in Figure 2, an airflow is introduced into the fragrance holding unit 101 of the fragrance dispensing device 100, and the introduced airflow is then temporarily directed into the temperature control unit 104. The airflow directed into the temperature control unit 104 is heated or cooled depending on the user's circumstances when using the fragrance. In some cases, the humidity of the airflow is also adjusted.

[0021] In the third step, the airflow that flows into the temperature control unit 104 splits into two; one flows back into the fragrance holding unit 101, and the other flows into the airflow channel section 113 located at the top of the airflow control unit 102.

[0022] In the fourth step, the airflow that has been flowed into the fragrance holding unit 101 is directed towards the vicinity of the fragrance holding member to form a fragrance-containing airflow Fk. The fragrance-containing airflow Fk is then directed into the airflow control unit 102. Meanwhile, the airflow that has been directed into the airflow channel section 113 is directed upwards to the opening 111 at the tip of the airflow control unit 102 as a control airflow Fu that controls the properties of the fragrance-containing airflow Fk.

[0023] In the fifth step, the fragrance-containing airflow Fk flowed into the airflow control unit 102 is stirred or exhausted by the regulated airflow Fh generated from the airflow adjustment fan 114, and then released or drawn in to the outside through the opening 111.

[0024] In the sixth step, the properties of the fragrance-containing airflow Fk are controlled by adjusting the intensity and direction of the controlled airflow Fu flowed above the opening 111 using the flap 112.

[0025] As an example of controlling the properties of the fragrance-containing airflow Fk, as shown in Figure 3, the fragrance-providing device 100 can vary the position of the flap 112 located at the tip of the airflow channel 113 downwards, allowing the controlled airflow Fu to flow as a descending airflow Fd from above to below the opening 111. This creates an air curtain of the descending airflow Fd at the opening 111, preventing the fragrance-containing airflow Fk from being released to the outside of the fragrance-providing device 100.

[0026] As described above, the fragrance dispensing device 100 according to this embodiment is equipped with an airflow control unit 102 near the tip opening 111, which allows the directionality and intensity of the airflow near the user's nose to be controlled by the collision and merging of the fragrance-containing airflow Fk and the controlled airflow Fu. As a result, the fragrance dispensing device 100 can make the user perceive the fragrance-containing airflow Fk, allowing them to feel the fragrance along with the breeze, or conversely, weaken the airflow near the nose to make it difficult to perceive, thereby creating a fragrance that drifts naturally.

[0027] Furthermore, the fragrance dispensing device 100 can prevent users from perceiving odors unintentionally, such as lingering odors or odor leakage, by generating an intake airflow or air shutter near the opening 111 when it is not desired for the user to perceive an odor at times other than when the fragrance is being presented. Therefore, the fragrance dispensing device 100 can provide fragrances to users at the appropriate time and prevent unintended fragrance dispensing.

[0028] In this embodiment, the fragrance dispensing device 100 is equipped with a temperature control unit 104, but the temperature control unit 104 is not required, and instead, a biological activity detection unit that detects biological activity can be provided. Furthermore, the fragrance dispensing device 100 can not only provide fragrance but also function as a deodorant by drawing in airflow around the user. In addition, the fragrance dispensing device 100 can prevent user droplets from flowing into and adhering to the fragrance dispensing device 100 through an air shutter created by the airflow.

[0029] 2. Second Embodiment (1) Example of the configuration of a fragrance dispensing device Next, with reference to Figure 4, an example configuration of the fragrance dispensing device 200 according to the second embodiment of this technology will be described. Figure 4 is a schematic diagram showing an example configuration of the fragrance dispensing device 200. The fragrance dispensing device 200 is more compact than the fragrance dispensing device 100 according to the first embodiment, and can provide fragrance at a position close to the user M's face, especially near the nose.

[0030] As shown in Figure 4, the fragrance dispensing device 200 according to this embodiment comprises a main body 201, a nose cover 202 attached to the main body 201, and an airflow control unit 203. Furthermore, the fragrance dispensing device 200 comprises a flap 204, a heart rate and posture detection unit 205, and a respiration detection unit 206. The tip of the nose cover 202 has an opening 207 for drawing in and expelling airflow.

[0031] The main unit 201 may be equipped with a fragrance holding member to hold fragrances and controls the operation of the entire fragrance dispensing device 200. The main unit 201 also has an information acquisition unit that acquires the user M's biological information, such as vital information and posture information.

[0032] The nose cover section 202 is positioned at the tip of the main body section 201 and has the function of concentrating the fragrance from the fragrance-containing airflow released from the main body section 201.

[0033] The airflow control unit 203 is located at the tip of the nose cover section 202. Specific examples of the airflow control unit 203 include axial fans, centrifugal fans, sirocco fans, diaphragm air pumps, linear air pumps, compression pumps, and chemical reaction type gas generators.

[0034] The flap 204 is attached near the opening 207 formed at the tip of the nose cover portion 202. As the flap 204, for example, an airflow-controlled variable multi-flap or a louver can be used to control the airflow.

[0035] The heart rate and posture detection unit 205 is, for example, located in the nose cover section 202 and equipped with sensors for detecting heart rate and posture. Similarly, the respiration detection unit 206 is, for example, located in the main body section 201 and equipped with a sensor for detecting the user M's breathing. Specific examples of the heart rate and posture detection unit 205 and the respiration detection unit 206 include TOF, infrared, image sensors, microwave radar, and millimeter-wave radar.

[0036] The heart rate and posture detection unit 205 and the respiration detection unit 206 can be provided in the fragrance dispensing device 200 as a bioactivity detection unit that detects the bioactivity of user M. The fragrance dispensing device 200 controls the fragrance-containing airflow in conjunction with the operation of the bioactivity detected by the bioactivity detection unit. Here, bioactivity refers to activities selected from a group consisting of user M's respiration, posture, heart rate, and combinations thereof. Note that posture includes not only the position and orientation of user M's face, but also the position and orientation of the nose.

[0037] (2) Example of operation of the fragrance dispensing device 1 Next, with reference to Figure 5, we will describe an example of the operation of the fragrance dispensing device 200, specifically example 1. Figure 5 is a schematic diagram illustrating an example of the operation of the fragrance dispensing device 200, specifically airflow presentation and airflow intake / exhaust. Figure 5A shows the timing at which we want the user M to perceive the fragrance, and Figure 5B shows the timing at which we do not want the user M to perceive the fragrance.

[0038] As shown in Figure 5A, when it is desired that the user M be able to perceive a fragrance, the fragrance-containing airflow generated by the main unit 201 is directed to the nose cover unit 202 and released to the outside through the opening 207. At this time, the fragrance-providing device 200 generates a controlled airflow according to the situation using the airflow control unit 203, and discharges the fragrance-containing airflow controlled by the controlled airflow towards the vicinity of the user M's nose to provide fragrance.

[0039] As shown in Figure 5B, if you do not want the user M to perceive a scent, the fragrance-containing airflow can be controlled by drawing in the fragrance-containing airflow through the opening 207 using a controlled airflow, or by exhausting the fragrance-containing airflow from the main body 201 to prevent residual fragrance or fragrance leakage. The fragrance-providing device 200 can also control the fragrance-containing airflow to allow the fragrance to waft through the air.

[0040] (3) Example of operation of the fragrance dispensing device 2 Next, with reference to Figure 6, we will describe an example of the operation of the fragrance providing device 200, specifically example 2. Figure 6 is a schematic diagram illustrating an example of the operation of airflow presentation and airflow sealing by the fragrance providing device 200. Figure 6A shows the timing when we want the user M to perceive the fragrance, and Figure 6B shows the timing when we do not want the user M to perceive the fragrance.

[0041] As shown in Figure 6A, if you want user M to experience a fragrance, the airflow control unit 203 generates a controlled airflow according to the situation, similar to the operation example 1 above, and the fragrance-containing airflow controlled by the controlled airflow is discharged towards the vicinity of user M's nose to provide the fragrance.

[0042] As shown in Figure 6B, if you do not want the user M to smell the fragrance, for example, a controlled airflow flowing from the top to the bottom of the nose cover portion 202 creates an air shutter at the opening 207, controlling the fragrance-containing airflow to prevent residual fragrance or fragrance leakage.

[0043] (4) Example of operation of the fragrance dispensing device 3 Next, with reference to Figure 7, we will describe Operation Example 3 of fragrance provision by the fragrance provision device 200. Figure 7 is a schematic configuration diagram illustrating an operation example in which the fragrance provision device 200 controls airflow using breathing detection. Figure 7A shows the case when user M inhales, and Figure 7B shows the case when user M exhales.

[0044] As shown in Figure 7A, when user M inhales, the breathing detection unit 206 detects the inhalation motion and provides user M with a fragrance-containing airflow controlled by a controlled airflow generated in accordance with the detected motion.

[0045] As shown in Figure 7B, when user M exhales, the breathing detection unit 206 detects the exhalation motion, and a controlled airflow is generated in accordance with the detected motion to inhale or exhaust the fragrance-containing airflow, preventing residual fragrance or fragrance leakage and avoiding unwanted aromas.

[0046] (5) Example of operation of the fragrance dispensing device 4 Next, with reference to Figure 7, we will describe an example of operation 4 of fragrance provision by the fragrance provision device 200. Figure 7 is a schematic configuration diagram illustrating an example of operation in which the fragrance provision device 200 controls airflow using heart rate detection. Figure 7A shows a case where fragrance is to be presented based on the user M's heart rate, and Figure 7B shows a case where fragrance is not to be presented based on the user M's heart rate.

[0047] As shown in Figure 7A, if the goal is to present an aroma based on the user M's heart rate, the heart rate and posture detection unit 205 detects the user M's heart rate. If the heart rate matches the desired level for aroma presentation, the airflow control unit 203 generates a controlled airflow in accordance with that heart rate, and the aroma is provided to the user M through a controlled fragrance-containing airflow.

[0048] As shown in Figure 7B, even if it is not desired to present fragrance based on user M's heart rate, the heart rate and posture detection unit 205 detects user M's heart rate. If the heart rate is such that fragrance presentation is not desired, the control airflow generated by the airflow control unit 203 is used to draw in or exhaust the fragrance-containing airflow in accordance with that heart rate, preventing residual fragrance or fragrance leakage and avoiding unwanted fragrances.

[0049] (6) Example of operation of the fragrance dispensing device 5 Next, with reference to Figure 8, we will describe an example of operation 5 of fragrance provision by the fragrance provision device 200. Figure 8 is a schematic configuration diagram illustrating an example of operation in which the fragrance provision device 200 controls airflow using posture detection. Figure 8A shows a case where fragrance is to be presented based on the user M's posture, and Figure 8B shows a case where fragrance is not to be presented based on the user M's posture.

[0050] As shown in Figure 8A, if it is desired to present an aroma based on the user M's posture, the heart rate and posture detection unit 205 detects the user M's posture. If the posture matches the desired one for aroma presentation, the airflow control unit 203 generates a controlled airflow according to that posture, and the aroma is provided to the user M through a controlled fragrance-containing airflow. In Figure 8A, the posture for aroma presentation is defined as when the user M brings their nose close to the fragrance providing device 200.

[0051] As shown in Figure 8B, even if the user M's posture does not warrant fragrance presentation, the heart rate and posture detection unit 205 detects the user M's posture. If the user M is in a posture where fragrance presentation is undesirable, the airflow control unit 203 generates a controlled airflow that is adjusted to that posture to inhale or exhaust the fragrance-containing airflow, preventing residual fragrance or fragrance leakage and avoiding unwanted fragrance. In Figure 8B, the posture in which the user M turns their nose away from the fragrance-providing device 200 is considered a posture in which fragrance presentation is undesirable.

[0052] (7) Example of operation of the fragrance dispensing device 6 Next, with reference to Figure 9, we will describe an example 6 of the operation of the fragrance dispensing device 200. Figure 9 is a schematic configuration diagram illustrating an example of airflow control operation that quiets the aromatic airflow by the fragrance dispensing device 200. Figure 9A shows a case where user M wants to feel both wind and fragrance, and Figure 9B shows a case where user M wants to feel the fragrance gently and does not want to feel wind.

[0053] As shown in Figure 9A, if user M wants to feel the wind and fragrance, the airflow control unit 203 generates a controlled airflow according to the situation, similar to the operation example 1 above, and discharges the fragrance-containing airflow controlled by the controlled airflow towards the vicinity of user M's nose to provide fragrance.

[0054] As shown in Figure 9B, if user M wants to experience the fragrance gently and does not want to feel the wind, the fragrance-containing airflow from the main unit 201 and the controlled airflow generated by the airflow control unit 203 are made to collide near user M's nose. As a result, the fragrance dispensing device 200 diffuses the fragrance-containing airflow, allowing the fragrance to be gently released near the nose without the user feeling the wind.

[0055] (8) Example of operation of the fragrance dispensing device 7 Next, with reference to Figure 10, we will describe an example of operation 7 of fragrance provision by the fragrance provision device 200. Figure 10 is a schematic configuration diagram illustrating an example of operation in which the fragrance provision device 200 uses fans differently for fragrance presentation and exhaust. Figure 10A shows the fragrance presentation mode (presentation side ON), and Figure 10B shows the fragrance exhaust mode (exhaust side ON). In this case, multiple fans are configured within the airflow control unit 203.

[0056] As shown in Figure 10A, in the fragrance presentation mode, a fragrance presentation fan is turned ON to present a fragrance to the user M, generating a controlled airflow for fragrance presentation. The fragrance providing device 200 controls the fragrance-containing airflow using the generated controlled airflow to provide the fragrance to the user M.

[0057] As shown in Figure 10B, in fragrance exhaust mode, in order to eliminate residual fragrance and fragrance leakage when no fragrance is being presented, a fragrance exhaust fan is turned ON to exhaust the fragrance-containing airflow away from or away from the user M's nose, thereby generating a controlled airflow for exhausting the fragrance. The fragrance provider 200 uses the generated controlled airflow to blow and exhaust all the air near the nose and the air near the tip opening 207 to the opposite side of the nose.

[0058] Furthermore, the fragrance dispensing device 200 can also continuously draw in and exhaust a fragrance-containing airflow from near the nose cover 202 in the background, for example, to prevent fragrance leakage or the release of odors from the nose cover 202 or other materials, even before the fragrance is dispensed to the user.

[0059] As described above, the fragrance dispensing device 200 according to this embodiment, like the fragrance dispensing device 100 according to the first embodiment, can provide fragrance to the user M at an appropriate time and prevent the dispensing of fragrance unintentionally. Furthermore, since the fragrance dispensing device 200 is equipped with a bioactivity detection unit formed by a heart rate and posture detection unit 205 and a respiration detection unit 206, it can acquire bioactivity information such as the user M's respiration, heart rate, and face orientation, and generate a fragrance-containing airflow near the opening 207 at the timing that the user M should smell, in accordance with these signals.

[0060] The fragrance-providing device related to this technology can be used, for example, in olfactory displays that artificially present scents along with images. Furthermore, the fragrance-providing device related to this technology can also be used in testing devices that measure olfactory ability.

[0061] Furthermore, this technology can be configured as follows: (1) A main body having an opening for releasing or drawing in a fragrance-containing airflow, An airflow control unit that controls the properties of the fragrance-containing airflow released or drawn in from the opening, A fragrance dispensing device equipped with the following features.
