DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same functions and components are denoted by the same reference numerals, and the description thereof will be omitted or will be briefly given.

[0011] (First embodiment) Fig. 1 is a block cross-sectional view showing an example of the configuration of an aroma diffuser 1 according to the first embodiment. The left side of Fig. 1 corresponds to the front side of the aroma diffuser 1, and the right side of Fig. 1 corresponds to the rear side of the aroma diffuser. FIG. 2 is a front external view showing an example of the aroma diffuser 1 according to the first embodiment. FIG. 3 is a rear external view showing an example of the aroma diffuser 1 according to the first embodiment. FIG. 4 is a perspective view showing an example of the aroma diffuser 1 according to the first embodiment. FIG. 5 is a cross-sectional perspective view showing an example of the aroma diffuser 1 according to the first embodiment.

[0012] The aroma diffuser 1 includes a housing 2, a connection terminal 3, a diffusion member 4, light emitting devices 5a and 5b, a scent diffusion device 6, a sound output device 7, an interface device 8, a communication device 9, and a control device 10.

[0013] The housing 2 is cylindrical. The housing 2 may have a shape in which the diameter (width) parallel to the bottom and top surfaces gradually increases from bottom to top (a shape that gradually becomes thicker from bottom to top and widens vertically from bottom to top). The housing 2 is not limited to a cylindrical shape, and may have other shapes such as a cube, sphere, or disk.

[0014] At least a portion (side surface portion 2a) of housing 2 is cylindrical and transparent or translucent so as to allow light to pass through. A portion of side surface portion 2a is a front surface portion 21. A portion of side surface portion 2a facing front surface portion 21 is a rear surface portion 22.

[0015] During the sleep-going action, for example, the entire side surface portion 2a may emit light, and during the wake-up action, for example, the front surface portion 21 of the side surface portion 2a may emit light.

[0016] A rear portion 22 of the side portion 2a is provided with a connection terminal 3 for connecting an electric wire to draw externally supplied power into the aroma diffuser 1, and an air inlet 11 for introducing cooling air into the aroma diffuser 1. The connection terminal 3 may be, for example, a USB (Universal Serial Bus) terminal. The air inlet 11 may be formed, for example, below the center of the rear portion 22 of the side portion 2a. The air inlet 11 may be formed above the connection terminal 3. The power supplied from the outside via the connection terminal 3 is supplied to, for example, the light-emitting devices 5a and 5b, the fragrance diffuser 6, the sound output device 7, the interface device 8, the communication device 9, and the control device 10.

[0017] The upper surface 2b of the housing 2 is formed with two holes 12a and 12b in the vertical direction for diffusing the atomized aromatic liquid upward.

[0018] Between the disk-shaped upper surface 2b of the housing 2 and the aroma diffuser body 1a from which the upper surface 2b has been removed, there is provided an opening 2c for discharging air (cooling air) from inside the housing 2 to the outside and for allowing sound emitted by the sound output device 7 to pass through.

[0019] The diffusing member 4 has a U-shaped cross section in the vertical direction and is housed inside the housing 2 in a downwardly convex state. The lower part of the diffusing member 4 is, for example, hemispherical. The other part of the diffusing member 4 is, for example, cylindrical and concentric with the opposing side surface 2a of the housing 2, and is located inside the side surface 2a of the housing 2.

[0020] The diffusing member 4 is disposed inside the housing 2 and is open upward. The diffusing member 4 is disposed to accommodate the light-emitting device 5b for sleep, which emits light downward. The diffusing member 4 may be, for example, translucent or transparent. In the first embodiment, the hemispherical bottom (lower part) of the diffusing member 4 is not in contact with the bottom of the housing 2 but is disposed floating above the bottom of the housing 2 via an air gap. In this case, the light emitted downward by the light-emitting device 5b for sleep passes through at least the lower part of the diffusing member 4 (the hemispherical bottom part of the diffusing member 4 floating above the bottom of the housing 2) and is radiated to the outside from at least the lower part of the side surface 2a of the housing 2. In the aroma diffuser 1, the wake-up light generated by the light-emitting device 5a passes through the diffusing member 4 and is radiated to the outside from a part (front surface 21) of the side surface 2a of the housing 2.

[0021] The diffusing member 4 may be, for example, an injection-molded member containing a polymer-based diffusing material that can attenuate transmitted light to a predetermined range, and may have a total light transmittance in the range of 50% to 70%, for example.

[0022] The light emitting devices 5a and 5b emit light to, for example, assist a user in falling asleep and waking up. In the first embodiment, the light emitting devices 5a and 5b may be, for example, LEDs (Light Emitting Diodes) or OLEDs (Organic Electro Luminescence).

[0023] In the first embodiment, a plurality of light-emitting devices 5a for waking up are provided inside the housing 2 and the diffusion member 4. The plurality of light-emitting devices 5a face the front surface 21 of the side surface 2a of the housing 2 via the diffusion member 4. The plurality of light-emitting devices 5a emit light horizontally to the outside via the diffusion member 4 and the front surface 21 of the side surface 2a. The plurality of light-emitting devices 5a are arranged in a substantially vertical direction.

[0024] The light emitting device 5a may emit light of a wavelength that suppresses melatonin production and promotes brain awakening. Specifically, the light emitting device 5a may emit light of 470 nm or more and 525 nm or less, more preferably 470 nm.

[0025] In the first embodiment, the light-emitting device 5b for sleep induction is disposed at the bottom inside the aroma diffuser 1. More specifically, the light-emitting device 5b is disposed inside the housing 2 and the diffusing member 4, facing the bottom surface of the housing 2 at a predetermined distance from the bottom surface of the housing 2. The light-emitting device 5b emits sleep induction light downward. The sleep induction light passes through the diffusing member 4 and at least the side surface 2a of the housing 2 and is emitted to the outside.

[0026] The air that enters the interior of the aroma diffuser 1 through the air intake 11 cools the light-emitting device 5b and the light-emitting device 5a, and is then released from the opening 2c formed between the upper surface 2b of the housing 2 and the aroma diffuser main body 1a.

[0027] Incidentally, heat dissipation fins 13 or the like may be formed in the air flow path from the air inlet 11 to the opening 2c, thereby improving the heat dissipation effect of the aroma diffuser 1.

[0028] The scent diffuser 6 is provided on the upper surface 2b of the housing 2. The scent diffuser 6 atomizes the aroma liquid in two aroma liquid containers (e.g., aroma bottles) using two ultrasonic vibrators 6a, 6b in accordance with commands from the control device 10, and sprays the atomized aroma liquid upward. The scent diffuser 6 will be described later with reference to Figures 6 to 11.

[0029] The sound output device 7 may be, for example, a speaker. The sound output device 7 is provided inside the housing 2 and the diffusion member 4 of the aroma diffuser 1. More specifically, the sound output device 7 is installed, for example, between the outer wall of the storage section that stores the aroma liquid container and the diffusion member 4, and is disposed obliquely toward the opening 2c. The sound output device 7 is also disposed below the ultrasonic vibrators 6a and 6b. The sound generated by the sound output device 7 is output to the outside through the opening 2c.

[0030] The interface device 8 receives operations and instructions from the user, and transmits a signal indicating the user's operations and instructions to the control device 10.

[0031] The interface device 8 receives a signal indicating the status from the control device 10 and notifies the user.

[0032] The communication device 9 receives a signal from an external device such as a smartphone, and transmits the received signal to the control device 9.

[0033] The communication device 9 receives signals from the control device 9 and transmits them to an external device.

[0034] The communication device 9 and the external device communicate with each other using, for example, standardized short-distance wireless communication or a wireless LAN (Local Area Network).

[0035] The control device 10 is provided inside the housing 2 and the diffusion member 4. The control device 10 controls the light-emitting devices 5a and 5b, the ultrasonic vibrators 6a and 6b provided in the fragrance diffuser 6, and the sound output device 7 based on signals received from the interface device 8 or the communication device 9, and transmits signals indicating the control status to the interface device 8 or the communication device 9. The control device 10 may include, for example, a processor 10a and a storage device 10b. The processor 10a executes a program 10c stored in the storage device 10b and controls the light-emitting devices 5a and 5b, the ultrasonic vibrators 6a and 6b provided in the fragrance diffuser 6, and the sound output device 7 using data 10d stored in the storage device 10b. The control device 10 may also be realized solely by hardware such as, for example, an electronic circuit.

[0036] The processor 10a executes the program 10c, for example, to function as a light control unit 10e, a scent control unit 10f, and a sound control unit 10g.

[0037] Processor 10a controls light-emitting devices 5a and 5b, ultrasonic vibrators 6a and 6b provided in fragrance diffuser 6, and sound output device 7 in accordance with set data 10d, signals received from interface unit 8, and signals received from communication device 9. In the first embodiment, processor 10a switches the control states of light-emitting devices 5a and 5b, ultrasonic vibrators 6a and 6b provided in fragrance diffuser 6, and sound output device 7 between sleep operation and wake-up operation.

[0038] The data 10d may include, for example, a set sleep onset time, a sleep onset operation time, a set wake-up time, a time before the set wake-up time at which the wake-up operation starts (wake-up operation start time), a wake-up operation time, etc. The data 10d may include, for example, a value used to determine the wake-up operation start time from the set wake-up time.

[0039] Data 10d may include, for example, data on the change in sleep light during the sleep-fall action time, data on the change in wake-up light during the wake-up action time, the amount of aroma liquid sprayed during the sleep-fall action time, the amount of aroma liquid sprayed during the wake-up action time, data on the change in volume during the sleep-fall action time, and data on the change in volume during the wake-up action time.

[0040] In the first embodiment, various pieces of information included in the data 10d may be set by the user, or may be calculated based on the user's settings and the program 10c.

[0041] The light control unit 10e performs control to emit light with different characteristics for, for example, a sleep-in action and a wake-up action.

[0042] During the sleep-inducing action, the light control unit 10e may turn on the light-emitting device 5b for sleep and emit soft sleep-inducing light generated from the light-emitting device 5b to the outside, for example, via the entire diffusion member 4 or the entire cylindrical side surface portion 2a of the housing 2. As a result, the aroma diffuser 1 emits soft sleep-inducing light that spreads evenly.

[0043] The light control unit 10e may emit the sleep-aid light through at least the lower hemispherical portion of the diffusing member 4, instead of through the entire diffusing member 4.

[0044] The light control unit 10e controls the light-emitting device 5b for falling asleep so that the light for falling asleep exhibits 1 / f fluctuation, for example.

[0045] The light control unit 10e performs a process of fading out the intensity of the sleep onset light during the set sleep onset operation time. For example, the light control unit 10e may vary the speed of the fade-out process within the range of the average sleep onset time period (10 to 20 minutes) for healthy adults. For example, the light control unit 10e may also perform the fade-out process for a predetermined period after the average sleep onset time period.

[0046] During the wake-up operation, the light control unit 10e turns on the light-emitting device 5a for waking up, and emits the strong wake-up light generated by the light-emitting device 5a to the outside via the front portion of the diffusion member 4 and the front portion 21 of the side portion 2a of the housing 2.

[0047] The wake-up light may be, for example, 300 lx (lux) or more.

[0048] The light control unit 10e may execute a fade-in process to gradually increase the intensity of the wake-up light emitted from the light-emitting device 5a from a first set time (for example, 20 minutes before) before the set wake-up time.

[0049] The light control unit 10e may execute a process in which the color of the wake-up light is a primarily red sunrise color at the start of the wake-up action, and gradually increases the wavelength of 470 nm or more and 525 nm or less, which suppresses melatonin production. Specifically, for example, the light control unit 10e may increase the intensity of red light more than the intensities of green light and blue light during sleep-onset action, and gradually decrease the intensity of red light. Alternatively, for example, the light control unit 10e may keep the intensity of red light constant and gradually increase the intensity of at least one of the intensities of green light and blue light during sleep-onset action.

[0050] The incense control unit 10f vibrates the ultrasonic vibrator 6a to diffuse the wake-up fragrance during the wake-up operation. The incense control unit 10f atomizes the wake-up aroma liquid in a set amount for the wake-up operation time. The incense control unit 10f may intermittently atomize the wake-up aroma liquid using the ultrasonic vibrator 6a.

[0051] The incense control unit 10f vibrates the ultrasonic vibrator 6b to diffuse the sleep fragrance during the sleep-inducing operation. The incense control unit 10f atomizes the sleep-inducing aroma liquid in a set amount for the sleep-inducing operation time during the sleep-inducing operation. The incense control unit 10f may intermittently atomize the sleep-inducing aroma liquid using the ultrasonic vibrator 6b.

[0052] The sound control unit 10g controls to change the sound output state of the sound output device 7 between the wake-up action and the sleep-fall action.

[0053] During the wake-up operation, the sound control unit 10g causes the sound output device 7 to output a wake-up sound. For example, during the wake-up operation, the sound control unit 10g may execute a fade-in process that gradually increases the volume from the wake-up operation start time, which is before the set wake-up time.

[0054] During the sleep-onset action, the sound control unit 10g causes the sound output device 7 to output a sound for falling asleep. For example, during the sleep-onset action, the sound control unit 10g may execute a fade-out process that starts reducing the volume at the start of the average sleep onset time period for healthy adults and gradually reduces the volume thereafter. For example, during the sleep-onset action, the sound control unit 10g may execute a fade-out process of the sound even during a period after the average sleep onset time period.

[0055] The scent diffuser 6 and the aroma liquid containers 14a and 14b will be described below with reference to FIGS.

[0056] FIG. 6 is a top perspective view showing an example of the installation relationship between the upper surface portion 2b of the aroma diffuser 1 according to the first embodiment and the aroma liquid containers 14a and 14b.

[0057] FIG. 7 is a bottom perspective view showing an example of the installation relationship between the upper surface portion 2b of the aroma diffuser 1 according to the first embodiment and the aroma liquid containers 14a and 14b.

[0058] FIG. 8 is a top perspective view showing an example of the storage portion 15 of the aroma liquid containers 14a, 14b in the aroma diffuser body 1a according to the first embodiment.

[0059] In the first embodiment, the aroma diffuser 1 is detachable between the top surface portion 2b and the aroma diffuser main body 1a, which is the remaining portion after removing the top surface portion 2b.

[0060] The aroma diffuser 6 diffuses the aroma liquid using ultrasonic vibrators 6a and 6b that are in contact with absorbent wicks provided in aroma liquid containers 14a and 14b that contain the aroma liquid. The ultrasonic vibrators 6a and 6b may also be referred to as piezoelectric elements.

[0061] The two aroma liquid containers 14a, 14b provided in the aroma diffuser 6 are screw-top containers. In addition, two mounting openings (recesses) 16a, 16b that fit into the screw tops of the aroma liquid containers 14a, 14b are formed on the back side of the upper surface 2b of the housing 2, similar to the screw caps of the aroma liquid containers 14a, 14b.

[0062] The screw mouths (outer surfaces of the bottle openings) of the two aroma liquid containers 14a, 14b with their caps removed fit into the inner surfaces of the two mounting openings 16a, 16b on the back side of the upper surface 2b of the housing 2, and the aroma liquid containers 14a, 14b are attached to the upper surface 2b.

[0063] The aroma liquid container 14a contains an aroma liquid for waking up, and the aroma liquid container 14b contains an aroma liquid for falling asleep.

[0064] The back side of the upper surface portion 2b is provided with a magnet 17a and a connector 18a. The connector 18a is electrically connected to the ultrasonic transducers 6a and 6b on the upper surface portion 2b.

[0065] The upper surface of the aroma diffuser main body 1a is provided with a storage portion 15, a magnet 17b, and a connector 18b. The connector 18b is electrically connected to the control device 10.

[0066] The upper surface portion 2b is stably attached to the aroma diffuser body 1a by the magnets 17a on the upper surface portion 2b and the magnets 17b on the aroma diffuser body 1a.

[0067] When the upper surface portion 2b is attached to the aroma diffuser body 1a, the connector 18a on the upper surface portion 2b and the connector 18b on the aroma diffuser body 1a are connected, enabling signals to be sent and received between the upper surface portion 2b and the aroma diffuser body 1a.

[0068] When the top surface 2b of the housing 2 is removed from the aroma diffuser main body 1a, a storage section 15 for storing the two aroma liquid containers 14a, 14b appears on the top surface of the aroma diffuser main body 1a. The user attaches the two aroma liquid containers 14a, 14b to the top surface 2b and then reattaches the top surface 2b of the housing 2 to the aroma diffuser main body 1a. At this time, the two aroma liquid containers 14a, 14b attached to the top surface 2b are housed in the storage section 15.

[0069] As explained with reference to Figure 1, the upper surface portion 2b is provided with two ultrasonic vibrators 6a, 6b. The ultrasonic vibrators 6a, 6b contact the upper ends of the absorbent wicks provided in the aroma liquid containers 14a, 14b. When the ultrasonic vibrators 14a, 14b vibrate, the aroma liquid in the aroma liquid containers 14a, 14b is atomized, and the atomized aroma liquid is dispersed upward from the holes 12a, 12b formed on the surface side of the upper surface portion 2b.

[0070] 9 is a vertical cross-sectional view showing an example of the aroma liquid container 14a according to the first embodiment. The aroma liquid container 14b has the same configuration as the aroma liquid container 14a in FIG.

[0071] The aroma liquid container 14 a includes a container body 30 , a holding portion 31 , an absorbent wick 36 , a spring 37 , a cap 32 , and a sub-cap 33 .

[0072] The container body 30 is, for example, bottle-shaped, contains the aromatic liquid L therein, and has a cylindrical upper opening 34. A threaded portion 35 is formed on the outer circumferential surface of the upper opening 34.

[0073] One end of the absorbent wick 36 is housed inside the container body 30, and the other end is located above the upper opening 34. The absorbent wick 36 absorbs the aroma liquid L upward. In the first embodiment, one end of the absorbent wick 36 contacts the inside of the bottom surface of the container body 30 via a spring 37.

[0074] The upper end of the spring 37 is attached to the lower end of the absorbent wick 36. More specifically, the inside of the upper end of the spring 37 is wrapped around the side of the lower end of the absorbent wick 36. This attaches the spring 37 to the absorbent wick 36. The lower end of the spring 37 contacts the inside of the bottom surface of the container body 30. For example, the outer diameter of the lower end of the spring 37 is smaller than the inner diameter of the upper opening 34 of the container body 30, which makes it easier to insert the spring 37 and the lower end of the absorbent wick 36 into the container body 30. The elastic force of the spring 37 stabilizes the position (e.g., vertical position) of the absorbent wick 36 and ensures appropriate contact between the upper end of the absorbent wick 36 and the ultrasonic vibrator 6a. The spring 37 has a trumpet shape, with the inner diameter of the lower winding of the spring 37 being larger than the inner diameter of the upper winding of the spring 37. More specifically, the vertical cross section of the spring 37 has a shape that widens toward the bottom, with the inner diameter of the spiral of the spring 37 increasing as it goes downward (in other words, a conical spring).

[0075] The holding portion 31 has a hole through which the absorbent wick 36 passes, supports the absorbent wick 36 , and is fixed to the upper opening 34 of the container body 30 .

[0076] A threaded portion 38 is formed on the inner peripheral surface of the cylindrical portion of the cap 32, and the cap 32 can be attached to and detached from the upper opening 34 of the container body 30, for example, by a screw mechanism. When the cap 32 is attached to the container body 30, it covers the upper opening 34 of the container body 30 and the upper end of the absorbent wick 36 protruding from the holding portion 31.

[0077] When the cap 32 is attached to the container body 30, the upper end of the absorbent wick 36 is inserted into the recess of the sub-cap 33, thereby preventing the aroma liquid L from evaporating from the absorbent wick 36. Furthermore, when the cap 32 is attached to the container body 30, the sub-cap 33 covers the upper end of the absorbent wick 36, thereby protecting the upper end of the absorbent wick 36 and preventing the position of the upper end of the absorbent wick 36 from changing. Furthermore, the sub-cap 33 contacts the inner circumferential surface of the cylindrical portion of the cap 32 and also contacts the holding portion 31 when the cap 32 is attached to the container body 30. For example, when the cap 32 is attached to the container body 30, the sub-cap 33 fits into the holding portion 31, preventing the aroma liquid L from evaporating from the absorbent wick 36 and preventing the aroma liquid L from leaking outside the fitting portion between the sub-cap 33 and the holding portion 31. The cap 32 and the sub-cap 33 may be integrally formed.

[0078] Fig. 10 is a cross-sectional view showing an example of the lower end side of the water-absorbent wick 36 provided in the aroma liquid container 14a according to the first embodiment. Fig. 10 shows a state in which the water-absorbent wick 36 is pushed into the bottom side of the aroma liquid container 14a.

[0079] The springs 37 have a trumpet shape, with the inner diameter of the lower winding being larger than the outer diameter of the upper winding. When the springs 37 are compressed, the lower ends of the springs 37 overlap in the radial direction, ensuring a sufficient compression width and shortening the vertical length of the springs 37. This reduces the number of parts in the aroma diffuser 1 and the aroma liquid container 14a, simplifying the configuration and allowing the aroma liquid L to be sucked up efficiently.

[0080] 11 is a cross-sectional view showing an example of the contact state between the upper end of the absorbent wick 36 provided in the aroma liquid container 14a according to the first embodiment and the ultrasonic vibrator 6a. The contact state between the upper end of the absorbent wick 36 provided in the aroma liquid container 14b and the ultrasonic vibrator 6b can also be similar to the contact state between the upper end of the absorbent wick 36 provided in the aroma liquid container 14a in FIG. 11 and the ultrasonic vibrator 6a.

[0081] The portion of the ultrasonic vibrator 6a that comes into contact with the absorbent wick 36 may protrude toward the absorbent wick 36. This allows the ultrasonic vibrator 6a and the upper end of the absorbent wick 36 to come into good contact with each other.

[0082] In the aroma diffuser 1 according to the first embodiment described above, the aroma liquid L in the aroma liquid containers 14a, 14b is atomized by the vibrations of the ultrasonic vibrators 6a, 6b. This allows the aroma liquid L to be atomized in the form of a fine mist without altering the components of the aroma liquid L, thereby effectively releasing the fragrance.

[0083] In the first embodiment, the aroma diffuser 1 emits light, fragrance, and sound during sleep initiation and wake-up actions, improving the user's sleep environment and making the user's sleep initiation and wake-up actions more comfortable.

[0084] In the first embodiment, the aroma diffuser 1 emits light having different characteristics in different directions during sleep-initiating and wake-up actions.

[0085] For example, in the first embodiment, the aroma diffuser 1 emits high-intensity wake-up light in a forward direction during wake-up. For example, the aroma diffuser 1 emits wake-up light with a wavelength of 470 nm or more and 525 nm or less, which suppresses melatonin production during wake-up. This suppresses melatonin production in the user during wake-up, thereby stimulating the user's brain to wake up.

[0086] For example, in the first embodiment, the aroma diffuser 1 emits light from the light-emitting device 5b toward the bottom of the aroma diffuser 1 during sleep initiation, transmitting soft light from the bottom of the aroma diffuser 1 to the entire side surface 2. This sleep initiation light can provide an articulating lighting effect. The color of the sleep initiation light may be an incandescent color. This provides the user with a relaxing space illuminated with sleep initiation light, promoting melatonin production in the user and helping them fall asleep.

[0087] In the first embodiment, the light-emitting device 5b for falling asleep is housed inside the cup-shaped diffusing member 4, which is floating above the bottom surface of the housing 2. In the first embodiment, during the act of falling asleep, the bottom surface of the cup-shaped diffusing member 4 emits light while floating in the housing 2 without contacting the bottom surface of the housing 2. As a result, in the first embodiment, during the act of falling asleep, an indirect lighting effect can be obtained by utilizing the floating space, and the area around the aroma diffuser 1 can be illuminated with soft light for falling asleep, providing a space where the user can relax.

[0088] In the first embodiment, light is emitted from inside the aroma diffuser 1 to the outside, passing through the diffusing member 4 and the side surface 2a of the housing 2. During sleep-initiating actions, soft sleep-initiating light spreads uniformly throughout the space in which the aroma diffuser 1 is installed, and during wake-up actions, strong light is emitted toward the user.

[0089] In the first embodiment, 1 / f fluctuation control is performed on the sleep-inducing light during the sleep-inducing action. Also, in the first embodiment, a gradual fade-out process is performed on the light intensity during the sleep-inducing action. This promotes a visually relaxing effect on the user and improves the sleep-inducing effect.

[0090] In the first embodiment, the wake-up light gradually becomes stronger by fade-in processing from before the set wake-up time, which can guide the user from deep sleep to light sleep and provide the user with a pleasant wake-up.

[0091] In the first embodiment, the wake-up light is emitted in a primarily red sunrise color at the start of the wake-up action, and the color of the wake-up light is gradually changed by gradually increasing the wavelength of light that suppresses melatonin production. This allows the user to wake up with less stress by utilizing physiological effects in addition to visual effects.

[0092] In the first embodiment, the sleep onset light can be faded out to suit the individual user in accordance with the average sleep onset time frame for healthy adults. This allows the user to be encouraged to fall asleep at a pace that varies depending on the user. In addition, in the first embodiment, the sleep onset light may be gradually faded out for a predetermined period of time even after the average sleep onset time frame has passed. This allows the user to fall asleep more appropriately.

[0093] In the first embodiment, an air intake 11 is provided on the underside of the rear portion 22 of the housing 2 of the aroma diffuser 1, and an opening 2c used as an exhaust port is provided on the upper part of the front portion 21 of the housing 2 of the aroma diffuser 1, thereby forming a heat dissipation flow path that does not impair the design of the aroma diffuser 1.

[0094] In the first embodiment, the aroma diffuser 1 sprays a set amount of aromatic liquid L with a relaxing effect for falling asleep during the sleep-initiating action, and a set amount of aromatic liquid L with an awakening effect for waking up during the wake-up action. In the first embodiment, it is possible to switch between the aromatic liquid L diffused during the sleep-initiating action and the aromatic liquid L diffused during the wake-up action, so that a scent with a relaxing effect for falling asleep can be diffused into the space during the sleep-initiating action, and a scent with an awakening effect for waking up can be diffused into the space during the wake-up action.

[0095] In the aroma diffuser 1 according to the first embodiment, the upper surface 2b and the aroma diffuser main body 1a are detachable. The upper surface 2b and the aroma diffuser main body 1a are connected by connectors 18a, 18b and magnets 17a, 17b. The aroma diffuser 1 includes ultrasonic vibrators 6a, 6b on the upper surface 2b of the housing 2, and aroma liquid containers 14a, 14b are disposed on the back side of the upper surface 2b of the housing 2. The aroma liquid L in the aroma liquid containers 14a, 14b is sucked upward by the absorbent wick 36. The vibration of the ultrasonic vibrators 6a, 6b, which are in contact with the upper end of the absorbent wick 36, causes the aroma liquid L to spray upward from the upper surface 2b of the housing 2. In this type of aroma diffuser 1, the aromatic liquid L is sprayed vertically, which prevents the atomized aromatic liquid L from being sprayed onto a person or wall next to the aroma diffuser 1, as occurs with sideways spraying. Furthermore, in the aroma diffuser 1, the aromatic liquid containers 14a, 14b can be easily replaced.

[0096] In the first embodiment, the aromatic liquid L is atomized using vibrations from the ultrasonic vibrators 6a, 6b on the upper surface portion 2b. Compared to atomizing the aromatic liquid L using a compressor, the atomization method according to the first embodiment does not require a complicated mist passage path and does not have any areas where the aromatic liquid L can become clogged. Therefore, the first embodiment can improve maintainability.

[0097] In the first embodiment, the top surface 2b of the housing 2, which includes the ultrasonic vibrators 6a, 6b, can be detached from the aroma diffuser main body 1a, and the aroma liquid containers 14a, 14b can be attached to the aroma diffuser 1 by fitting the screw openings of the aroma liquid containers 14a, 14b into the mounting openings 16a, 16b on the back side of the top surface 2b. This allows the aroma liquid containers 14a, 14b to be easily and safely installed in the aroma diffuser 1, and the aroma liquid containers 14a, 14b can be easily replaced, improving maintainability.

[0098] In the first embodiment, a spring 37 is attached to the lower end of the absorbent wick 36 provided in the aroma solution containers 14a, 14b. This spring 37 improves the contact between the absorbent wick 36 and the ultrasonic vibrators 6a, 6b. The spring 37 is a trumpet-shaped conical spring with an inner diameter larger at the lower portion than at the upper portion. When the spring 37 is compressed, the windings at the lower portion of the spring 37 overlap radially, ensuring a sufficient compression width and shortening the length of the spring 37. This reduces the number of parts in the aroma diffuser 1 and the aroma liquid containers 14a, 14b, simplifying their configuration and enabling the aroma solution L to be drawn up efficiently.

[0099] In the first embodiment, an opening 2c is formed between the upper surface 2b of the aroma diffuser 1 and the aroma diffuser body 1a to allow passage of sound generated from a sound output device 7 provided inside the aroma diffuser. The sound output device 7 is disposed at an angle toward the opening 2c. The sound output device 7 is also installed inside the aroma diffuser 1 at a lower position than the ultrasonic vibrators 6a and 6b. This aroma diffuser 1 can prevent the atomized aroma liquid L from adhering to the sound output device 7 without interfering with light emission, and can provide the user with a comfortable sleep and wake-up experience through the light, scent, and sound.

[0100] The aroma diffuser 1 according to the first embodiment can achieve different volume and sound changes during sleep initiation and wake-up. For example, during sleep initiation, the aroma diffuser 1 reduces the volume to coincide with the start time of the average sleep onset time for healthy adults, and then gradually reduces the volume thereafter, thereby encouraging the user to fall asleep. For example, during wake-up, the aroma diffuser 1 gradually increases the volume from a predetermined time before the set wake-up time to induce the user to transition from deep sleep to light sleep, and then emits the set volume at the set wake-up time to encourage the user to wake up.

[0101] (Second embodiment) The second embodiment is a modification of the first embodiment, and the description of the same parts as those in the first embodiment will be omitted, and only the different parts will be described in detail.

[0102] FIG. 12 is a front perspective view showing an example of the relationship between the light emitting device 5a for waking up according to the second embodiment and the first lens 39. As shown in FIG.

[0103] 12 illustrates the wake-up light-emitting device 5a and the first lens 39 provided on the substrate 40, and omits other parts. The back surface of the substrate 40 may be provided with the heat dissipation fins 13 shown in FIG.

[0104] As described in the first embodiment above, the plurality of light-emitting devices 5a are arranged vertically inside the housing 2 and the diffusing member 4. The plurality of light-emitting devices 5a face the front surface 21 of the side surface 2a of the housing 2 via the first lens 39 and the diffusing member 4. Wake-up light generated by the plurality of light-emitting devices 5a passes through the first lens 39, the diffusing member 4, and the front surface 21 of the side surface 2a of the housing 2 from the inside, and is irradiated outward.

[0105] The first lens 39 has a dimming function that equalizes the intensity of light passing through the first lens 39, increases directivity, and converts multiple wake-up lights into directional planar wake-up light. In the second embodiment, for example, the first lens 39 has a corrugated outer surface in its horizontal cross section, thereby achieving the dimming function of the wake-up light generated by the multiple light-emitting devices 5a. The first lens 39 converts the multiple light-emitting devices 5a, which are point light sources, into a planar light source with increased directivity.

[0106] In addition, there may be no diffusion member 4 outside the first lens 39, and the wake-up light generated by the multiple light-emitting devices 5a may be transmitted through the first lens 39 and the front portion 21 of the side portion 2a of the housing 2 and irradiated outward.

[0107] FIG. 13 is a cross-sectional view showing an example of the relationship between a light-emitting device 5b for use in falling asleep, a second lens 41, and a diffusing member 4 according to the second embodiment.

[0108] 13 illustrates the wake-up light-emitting device 5b, the second lens 41, and the diffusion member 4 provided on the substrate 42, and omits other parts. The substrate 42 may be provided on its upper surface with the heat dissipation fins 13 shown in FIG. 1.

[0109] In the second embodiment, downward light emitted by the light-emitting device for falling asleep 5b is refracted by the second lens 41, irradiated onto the entire inner surface of the diffusing member 4, and then transmitted through the diffusing member 4 and the side surface 2a of the housing 2 to be emitted to the outside. The second lens 41 converts the light-emitting device for falling asleep 5b, which is a point light source, into a surface light source. The second lens 41 has the function of homogenizing the intensity of the sleep-initiating light transmitted through the second lens 41 during the sleep-initiating action and dimming the downward light emitted by the light-emitting device for falling asleep 5b so that it illuminates the entire side surface 2a.

[0110] The second lens 41 has, for example, an ω-shaped (or W-shaped) vertical cross section. Specifically, the first surface (upper surface) of the second lens 41 has a protruding center and a circumferential portion, and a recessed portion excluding the center and the circumferential portion. Conversely, the second surface (lower surface) of the second lens 41 has a recessed center and a circumferential portion, and a protruding portion excluding the center and the circumferential portion. Downward light generated by the light-emitting device for sleep induction 5b enters the second lens 41 from the convex portion at the center of the first surface of the second lens 41. A portion of the light inside the second lens 41 is refracted or reflected by the second surface of the second lens 41, for example, and emitted to a position higher than the light-emitting device for sleep induction 5b. Due to the action of the second lens 41, light for induction to sleep is emitted from the side surface 2 of the aroma diffuser 1.

[0111] In the second embodiment described above, the wake-up light generated by the wake-up light-emitting device 5b is radiated to the outside after passing through the first lens 39, the diffusing member 4, and the front part 21 of the housing 2. By providing this first lens 39, it is possible to reduce glare while maintaining an appropriate intensity of the wake-up light, and it is possible to irradiate a strong light that is not uncomfortable for the user when waking up.

[0112] Furthermore, by using the first lens 39, the plurality of light emitting devices 5a, which are point light sources, are converted into a surface light source, and the directivity is further increased, thereby reducing the power consumption required to generate the wake-up light.

[0113] In the second embodiment, the fall-asleep light generated by the light-emitting device 5b for falling asleep passes through the second lens 41 and is irradiated onto the entire inner surface of the diffusing member 4, and then passes through the diffusing member 4 and the entire side portion 2a of the housing 2 and is irradiated to the outside.

[0114] By providing this second lens 41, the quality of the lighting effect when falling asleep can be improved.

[0115] (Third embodiment) The third embodiment will explain a specific example of the control of light, scent, and sound in the aroma diffuser 1 according to the first and second embodiments.

[0116] FIG. 14 is a front perspective view showing an example of the upper surface portion 2b of the aroma diffuser 1 according to the third embodiment.

[0117] The top surface of the upper surface 2b is provided with two holes 12a, 12b for spraying atomized aromatic liquid and a button 8a, and the side of the upper surface 2b is provided with a sleep mode display 8b, a wake-up mode display 8c, and a communication status display 8d. The sleep mode display 8b, the wake-up mode display 8c, and the communication status display 8d may be, for example, an LED or an OLED.

[0118] The button 8a, the sleep mode display section 8b, the wake-up mode display section 8c, and the communication status display section 8d correspond to the interface device 8 described in the first embodiment.

[0119] The control device 10 controls the aroma diffuser 1 in response to the user's operation of the button 8a (e.g., long press, short press, etc.). For example, the control device 10 starts the sleep initiation operation when the button 8a is pressed or when the set sleep time arrives. For example, the control device 10 stops the sleep initiation operation when the button 8a is pressed during the sleep initiation operation. For example, the control device 10 starts the wake-up operation when the wake-up operation start time arrives, which is before the set wake-up time. For example, the control device 10 stops the wake-up operation when the button 8a is pressed during the wake-up operation.

[0120] The control device 10 causes the sleep mode display section 8b to emit light during the sleep action, causes the wake-up mode display section 8c to emit light during the wake-up action, and causes the communication status display section 8d to emit light during communication.

[0121] The control device 10 can communicate with an external device such as a smartphone via the communication device 9. The smartphone starts an app, accepts user settings or commands, and transmits the user settings or commands to the aroma diffuser 1. The communication device 9 receives the settings or commands from the smartphone and transmits the settings or commands to the control device 10.

[0122] FIG. 15 is a diagram showing an example of switching states of the operation of the aroma diffuser 1 according to the third embodiment.

[0123] The control device 10 in the standby state starts the sleep initiation operation when the set sleep initiation time arrives.

[0124] The control device 10 enters a wake-up standby state when the sleep-initiating operation time has elapsed since the set sleep-initiating time (when the sleep-initiating operation end time has elapsed), or when an instruction to stop the sleep-initiating operation is received using the button 8a.

[0125] The control device 10 in the wake-up standby state starts the start-up operation when the wake-up operation start time comes, which is earlier than the set wake-up time.

[0126] The control device 10 goes into a standby state when the wake-up operation time has elapsed since the wake-up operation start time (when the wake-up operation end time has elapsed), or when an instruction to stop the wake-up operation is received by the button 8a.

[0127] FIG. 16 is a graph showing an example of sleep induction control by the aroma diffuser 2 according to the third embodiment.

[0128] The set sleep onset time and the sleep onset action time or sleep onset action end time can be set by the user operating an external device such as a smartphone.

[0129] When the set time for falling asleep arrives or when an instruction to start the sleep action is received using button 8a, the control device 10 starts the sleep action, generates a sleep light and sound, and starts intermittent spraying of aroma liquid L for falling asleep.

[0130] The control device 10 then gradually reduces the sleep light and sound.

[0131] Then, when the sleep-onset operation time has elapsed since the set sleep-onset time, or when the sleep-onset operation end time has elapsed, the control device 10 ends the generation of the sleep-onset light and sound and the spraying of the aroma liquid.

[0132] FIG. 17 is a graph showing an example of wake-up control of the aroma diffuser 1 according to the third embodiment.

[0133] The set wake-up time, the first set time, and the wake-up action time (or the second set time or the wake-up action end time) can be set by the user by operating an external device such as a smartphone.

[0134] When the wake-up operation start time arrives, which is a first set time before the set wake-up time, the control device 10 starts the wake-up operation, generates wake-up light and sound, and starts intermittent spraying of the wake-up aroma liquid L. The control device 10 gradually increases the wake-up light and sound from the wake-up operation start time.

[0135] The control device 10 terminates the generation of the wake-up light and sound and the spraying of the aroma liquid when the wake-up operation time has elapsed from the wake-up operation start time, when a second set time has elapsed from the wake-up operation set time, when the wake-up operation end time has elapsed, or when an instruction to end the wake-up operation is received by button 8a.

[0136] Fig. 18 is a graph showing a first example of changes in the wake-up light of the aroma diffuser 1 according to the third embodiment. The coefficients shown on the vertical axis of Fig. 18 correspond to the intensities of R (red), G (green), and B (blue) lights. The horizontal axis of Fig. 18 represents elapsed time.

[0137] At the start time of the wake-up operation, the coefficient of R is the largest, 100%, the coefficient of B (blue) is the smallest, 0%, and the coefficient of G is 40% between the coefficient of R and the coefficient of B.

[0138] As time passes from the start time of the wake-up action, the R coefficient gradually decreases, and the blue and green coefficients increase.

[0139] At the end of the wake-up operation, G is the largest at 100%, and the coefficients of R and B are both 70%.

[0140] Fig. 19 is a graph showing a second example of changes in the wake-up light of the aroma diffuser 1 according to the third embodiment. The coefficients shown on the vertical axis of Fig. 19 correspond to the intensities of R (red), G (green), and B (blue) lights. The horizontal axis of Fig. 19 represents elapsed time.

[0141] At the start time of the wake-up operation, the coefficient of R is the largest at 80%, the coefficient of B (blue) is the smallest at 0%, and the coefficient of G is 10% between the coefficient of R and the coefficient of B.

[0142] In the example of FIG. 19, the coefficient of R is set to be constant.

[0143] The G coefficient gradually increases from 10% as time passes, reaching 60% at the first elapsed time (e.g., 14 minutes), then gradually increases further to 100% at the second elapsed time (e.g., 16 minutes), and then remains at 100%.

[0144] The coefficient of B gradually increases from 0% as time passes, reaching 10% at the first elapsed time (e.g., 14 minutes), then gradually increasing further to 70% at the second elapsed time (e.g., 16 minutes), and then remaining at 70%.

[0145] In the above-mentioned Figures 18 and 19, the wake-up light is gradually changed from a predominantly red color to a wavelength of 470 nm or more and 525 nm or less, which suppresses the production of melatonin.

[0146] In the third embodiment described above, as described in the first embodiment, it is possible to provide the user with less stress when falling asleep and waking up. Furthermore, in the third embodiment, it is possible to provide the user with high operability.

[0147] The present invention is not limited to the above-described embodiments, and can be realized by modifying the components within the scope of the gist of the invention in the implementation stage. Furthermore, various inventions can be formed by appropriately combining multiple components disclosed in the above-described embodiments. For example, some components may be omitted from all the components shown in each embodiment. Furthermore, components from different embodiments may be appropriately combined.
