Definitions
- the present invention relates to an aroma display and, more specifically, to an improvement of an aroma display that is able to emit different scents by holding a plurality of aroma cartridges.
- a desirable aroma display is one that is able to diffuse a desired scent in a certain limited scope at one time point and is able to blow out that scent and switch to another scent at another time point.
- aroma cartridges a plurality of cartridges (referred to as aroma cartridges), each containing a pre-selected scent emission source (referred to as a scent source), to load an aroma display with them, and emit the desired scent via the relevant cartridge.
- scent source a pre-selected scent emission source
- a scent channel for carrying the scent from the scent source in the cartridge is formed in the cartridge, and a mechanism for feeding air into the cartridge at desired times is provided by the aroma display, so that the scent is emitted through the channel to the aroma display's exterior.
- the aroma display also provides a mechanism for emitting air free of any scent component, having an air emission opening near the scent channels. To switch scents after one scent is emitted, the air-emitting mechanism emits a blast of air to blow out the scented air, and then another scent is emitted. Thus, scents can be switched at any timing, avoiding improper blending of scents.
- JP2014-092673A Such a technique is disclosed in JP2014-092673A.
- the technique disclosed in JP2014-092673A is as described above.
- An opening is formed in the housing of an aroma display for emitting the scent to the outside.
- the scent channels, from their respective aroma cartridges and air emission openings, are all connected to this opening.
- Each aroma cartridge is releasably held in the housing of the aroma display.
- An opening for introducing air into the aroma cartridge is formed at a prescribed portion of each aroma cartridge.
- a wind source containing a diaphragm with a piezoelectric element attached is mounted corresponding to each aroma cartridge.
- the diaphragm vibrates and introduces air into the aroma cartridge through a nozzle provided on the wind source and through the opening of the aroma cartridge. From the aroma cartridge that received the introduced air, scented air corresponding to the scent source therein is emitted to the outside through the scent channel.
- a wind source is provided as an air-emitting mechanism, which, having a structure similar to that of the wind sources attached to the aroma cartridges, can feed a larger amount of air, free of any scent, with stronger force, to the air emission opening.
- the aroma display having the above-described structure is able to freely switch scents by selecting the wind source or sources to be operated. Further, by simultaneously operating the air-emitting mechanism for emitting scent-free air, it is possible to prevent the undesired blending of scents.
- the wind source to be operated and its timing may be controlled by sending an external command to the aroma display. Therefore, the aroma display can achieve beautiful effects of emitting desired scents appropriately by causing the desired wind sources to operate, for example, at desired timings in movies or animated films.
- the conventional aroma display uses piezoelectric elements as wind sources in the mechanisms for emitting air and scent, it has the following drawbacks. While a wind source using a piezoelectric element can suppress the noise level, it can feed only a small amount of air. It poses no problem when the distance between the aroma display and a user is short, as in the case where the aroma display is used as an accessory of a PC. However, when it is used in a wider space, for example, when multiple people watch a TV, it is difficult to spread a scent far and wide or to dissipate the emitted scent immediately.
- a desirable aroma display is one that can emit a large volume of air to spread a scent far and wide, can dissipate the emitted scent, and can also emit a scent in a controlled manner within a limited space.
- Preferred embodiments of the present invention provide booster devices that are each able to increase and decrease a volume of air flow that carries scents emitted from aroma cartridges.

- the PC reads the scenario and reproduces the scenario in synchronization with the movie.
- the PC transmits a command to the wireless communication device of the aroma display 50 and a specific scent is emitted from the aroma cartridge with the designated identifier at the timing designated by the scenario.
- the wireless communication device applies AC voltage at the designated timing for the designated time period to the micro blower 234 of the cartridge loading section loaded with the designated scent. Accordingly, the designated scent is emitted from the aroma display 50 at the timing and for the duration as designated by the scenario.
- the micro blower 184 inside the aroma display 50 or the fan 326 in the housing 310 may be controlled to be operated simultaneously with the emission of a scent.
- scent-free air is emitted to an exterior of the aroma display 50 from the opening 68 shown in FIGS. 1 and 3 .
- a scent from an aroma cartridge flows out from cap 324 of the booster 300 . Accordingly, the user is able to observe the scent.
- the air flow generated by the micro blower 184 is weak and does not reach very far. Therefore, the scent is observed only in a close vicinity of the booster 300 .

- the air flow is weak and, therefore, only the scent lingering in the vicinity of the booster 300 is able to be dissipated.
- the scent generated by the aroma display 50 can be carried far and wide by using the fan 326 . Further, the scent lingering in a wide range is able to be quickly dissipated. In addition, only the scent-free air is able to be emitted to a far distance. Accordingly, a scent is able to be emitted throughout a wide area and the mixing of scents is able to be prevented when the scents are switched.
- the aroma display 50 is able to be freely be attached to/detached from the booster 300 . Therefore, for example, a plurality of the aroma displays 50 loaded with different aroma cartridges may be switched easily for use. Further, the aroma display 50 is able to be removed from the booster 300 , and the aroma display 50 may be operated by itself.
- the aroma display 50 in accordance with the first preferred embodiment described above provides emission of a scent to a wider space or dissipation of a scent from a wider space as compared with a conventional aroma display. Accordingly, operation of the aroma display 50 is able to be widened from personal use to more general use by a larger number of people. However, further improvements may be provided to let users more fully enjoy the scents.
- a scent is experienced not only by olfaction or sense of smell. In most cases, a scent is experienced with temperature. As an example, when one takes a sip of coffee, the aroma of coffee is experienced with its warmth. On the contrary, one experiences the scent of plants and trees with coolness in morning winds in the grass or in the forest.
- a second preferred embodiment of the present invention has provides only the function of emitting scents but also a function of heating or cooling the air containing scent, fit for the scene when the scent is presented.

- the heat exchanger 424 includes an overhanging structure 500 , a Peltier module 501 and a heat sink 502 .
- the Peltier module 491 is a plate-shaped semiconductor device and when a DC in a predetermined direction is applied, a heat absorbing surface of the Peltier module 491 cools an object that is in touch with the surface and radiates heat to a heat radiating surface of the Peltier module 491 . When the direction of current is reversed, the heat absorbing and radiating surfaces are switched. In other words, the Peltier module 491 has a heat exchanging function.
- the width of the Peltier module 491 is equal or substantially equal to the width of opening 510 , and the upper edge of the Peltier module 491 is in air-tight contact with an upper edge of the opening 510 .

- the booster 400 includes the same or similar structure as that of the booster 300 in accordance with the first preferred embodiment.
- the heat radiating surface and the cooling surface of the Peltier module 491 are switched. Therefore, the booster 400 is able to heat the air by reversing the direction of current fed to the Peltier module, rather than heating the air by using the nichrome wire. In that case, the nichrome wire 470 is unnecessary.
- both the Peltier module 491 and the nichrome wire 470 may be operated to preheat the air by the Peltier module 491 and additionally heat the air by the nichrome wire 470 . Such operation is able to be implemented by controlling signals or currents applied externally to the booster 400 .
- the operation of the booster 400 is the same as or similar to the operation of the booster 300 in accordance with the first preferred embodiment.
- the booster 400 is different from the booster 300 in that the booster 400 is able to heat or cool the air generated by the fan 326 and passing through the air passages 382 and 384 , in response to an external control signal.
- FIG. 13 shows air flow when the booster 400 is in operation.

- FIG. 14 shows, in enlargement, the portion of FIG. 13 indicated by reference numeral 14 .
- the flow of air in the booster 400 is the same as or similar to the flow of air in the booster 300 in accordance with the first preferred embodiment. What is different is that the air passing through the air passages 382 and 384 can be cooled or heated.
- a portion of the air generated by the fan 326 will be an air flow 550 that flows through the air passage 382 between the conical section 352 and the heat absorbing surface 562 of the Peltier module 491 .
- the air flow 550 is deprived of its heat by the heat absorbing surface 562 and cooled.
- Another portion of air generated by the fan 326 is an air flow 552 split from the air flow 550 by the Peltier module 491 and guided to the side of the heat radiating surface 560 of the Peltier module 491 , which air flow deprives the heat radiating surface 560 of heat and passes through the heat sink 492 , to be discharged outside from an opening of the heat sink 492 .
- the air flowing through the air passages 382 and 384 is able to be cooled, and thus a scent emitted from the aroma display 50 is able to be carried and spread with cold air.
- a scent emitted from the aroma display 50 is able to be carried and spread with cold air.
- a portion of the air flow from the fan 326 is guided by the Peltier module 491 to the side of the heat sink 492 , deprives the radiating surface 560 of heat by the heat sink 492 , and dissipates the heat into the surrounding air. Accordingly, the Peltier module 491 is able to be efficiently operated.
- the air flowing through the air passages 382 and 384 is able to be heated by feeding current to the nichrome wire 470 without feeding any current to the Peltier module 491 .
- the air is heated by feeding current to the nichrome wire 470 and a scent of coffee emitted from the aroma display 50 is carried with heated air. Accordingly, the scent of coffee spreads with warm air and the user is able to observe the realistic sense of tasting a cup of coffee.
- the booster 400 in addition to simply spreading a scent, dissipating a scent at a predetermined timing, or switching scents, the temperature of air carrying the scent is able to be adjusted in accordance with the scent. Accordingly, communication by scents is able to have a stronger effect. If heat only generated by the nichrome wire 470 is not sufficient, the current applied to the Peltier module 491 may be reversed to preheat the air passing through the channel 384 and thus to increase the heating of the air. If the Peltier module 491 provides sufficient heating and cooling capacity, the nichrome wire 470 may be omitted.

Description
- The present invention relates to an aroma display and, more specifically, to an improvement of an aroma display that is able to emit different scents by holding a plurality of aroma cartridges.
- Human communication is performed in various modes based on human senses. Most frequently used are visual and auditory communications. By contrast, olfaction or sense of smell, on which humans rely considerably, is hardly used in communication. However, if the sense of smell can be utilized in addition to visual and auditory senses, communication would be more effective and various people would be able to share their experiences more profoundly.
- Focusing on this point, recently, devices have been proposed which are used with audio-visual reproducing devices, for example, television receivers, personal computers and game machines to generate scents fitting for the time and place. In the present specification, a device that generates scents fitting for scenes will be referred to as an “aroma display”.
- Emission of a certain scent supposed to be fit for a certain scene would not be very effective if there is any lingering scent produced immediately before. Therefore, a desirable aroma display is one that is able to diffuse a desired scent in a certain limited scope at one time point and is able to blow out that scent and switch to another scent at another time point.
- Without the ability to freely switch from one scent to another, an aroma display cannot make full use of scents. For this purpose, one possible approach is to prepare a plurality of cartridges (referred to as aroma cartridges), each containing a pre-selected scent emission source (referred to as a scent source), to load an aroma display with them, and emit the desired scent via the relevant cartridge.
- A scent channel for carrying the scent from the scent source in the cartridge is formed in the cartridge, and a mechanism for feeding air into the cartridge at desired times is provided by the aroma display, so that the scent is emitted through the channel to the aroma display's exterior. Aside from the mechanism that emits scents from the cartridges, the aroma display also provides a mechanism for emitting air free of any scent component, having an air emission opening near the scent channels. To switch scents after one scent is emitted, the air-emitting mechanism emits a blast of air to blow out the scented air, and then another scent is emitted. Thus, scents can be switched at any timing, avoiding improper blending of scents.
- Such a technique is disclosed in JP2014-092673A. The technique disclosed in JP2014-092673A is as described above. An opening is formed in the housing of an aroma display for emitting the scent to the outside. The scent channels, from their respective aroma cartridges and air emission openings, are all connected to this opening. Each aroma cartridge is releasably held in the housing of the aroma display. An opening for introducing air into the aroma cartridge is formed at a prescribed portion of each aroma cartridge. At the portion of the aroma display which corresponds to this opening when an aroma cartridge is held by the aroma display, a wind source containing a diaphragm with a piezoelectric element attached is mounted corresponding to each aroma cartridge. By applying an AC voltage to the piezoelectric element, the diaphragm vibrates and introduces air into the aroma cartridge through a nozzle provided on the wind source and through the opening of the aroma cartridge. From the aroma cartridge that received the introduced air, scented air corresponding to the scent source therein is emitted to the outside through the scent channel.
- Further, at the portion corresponding to the root of air emission opening of the aroma display, a wind source is provided as an air-emitting mechanism, which, having a structure similar to that of the wind sources attached to the aroma cartridges, can feed a larger amount of air, free of any scent, with stronger force, to the air emission opening.
- The aroma display having the above-described structure is able to freely switch scents by selecting the wind source or sources to be operated. Further, by simultaneously operating the air-emitting mechanism for emitting scent-free air, it is possible to prevent the undesired blending of scents. The wind source to be operated and its timing may be controlled by sending an external command to the aroma display. Therefore, the aroma display can achieve magnificent effects of emitting desired scents appropriately by causing the desired wind sources to operate, for example, at desired timings in movies or animated films.
- Because the conventional aroma display uses piezoelectric elements as wind sources in the mechanisms for emitting air and scent, it has the following drawbacks. While a wind source using a piezoelectric element can suppress the noise level, it can feed only a small amount of air. It poses no problem when the distance between the aroma display and a user is short, as in the case where the aroma display is used as an accessory of a PC. However, when it is used in a wider space, for example, when multiple people watch a TV, it is difficult to spread a scent far and wide or to dissipate the emitted scent immediately.
- In order to solve such problems, it is possible to provide the wind source of the air emission mechanism with a stronger fan. In that case, however, the fan noise would be problematic, and the aroma display would be larger. Further, a larger fan leads to a problem in which it becomes difficult to maintain the emission of scent to a limited small area near the aroma display. A desirable aroma display is one that can emit a large volume of air to spread a scent far and wide, can dissipate the emitted scent, and can also emit a scent in a controlled manner within a limited space.
- Preferred embodiments of the present invention provide booster devices that are each able to increase and decrease a volume of air flow that carries scents emitted from aroma cartridges.
- According to a first preferred embodiment of the present invention, a booster device of an aroma display is able to significantly improve the scent-emitting ability of the aroma display. The aroma display has a columnar shape including first and second surfaces and a side surface. The first surface includes an emitting opening to emit a scent. A wind source to emit the scent to an exterior of the aroma display is provided in the aroma display. The booster device includes a housing including the aroma display, and a fan provided in the housing. The housing includes a cylindrical outer housing including an air inlet to take in air and a holder holding the aroma display in the housing. The holder holds the aroma display to define an air passage, through which air from the fan passes, between the outer housing and the aroma display.
- Preferably, for example, both the aroma display and the outer housing have a central axis, and the holder holds the aroma display with central axes of the aroma display and the outer housing are parallel or substantially parallel to each other.
- More preferably, for example, the holder holds the aroma display to align the central axis of the aroma display with the central axis of the outer housing.
- More preferably, for example, the booster device for an aroma display further includes a conical or substantially conical structure that narrows the air flow generated by the fan, provided at an end portion of the outer housing on the side of the first surface of the aroma display.
- Preferably, for example, the booster device for an aroma display further includes a heater provided in the air passage to heat air passing through the air passage.
- More preferably, for example, the booster device for an aroma display further includes a heat exchanger provided in the outer housing to conduct heat exchange between the air passing through the air passage and air outside the outer housing.
- More preferably, for example, the heat exchanger is provided to discharge heat of the air passing through the air passage to an exterior of the outer housing and to cool the air passing through the air passage.
- Preferably, for example, the heat exchanger is provided to introduce heat of the air outside the outer housing into the outer housing to heat the air passing through the air passage.
- More preferably, for example, an opening is provided on a side surface of the outer housing, the heat exchanger includes a Peltier module including first and second surfaces to contact respective objects of heat exchange, and the Peltier module is attached to the opening with the first surface facing the air passage and the second surface facing outside of the outer housing.

- More preferably, for example, the booster device for an aroma display further includes a heat insulator located between the air passage and the aroma display.
- More preferably, for example, the heat insulator is provided between the air passage and at least a portion of the aroma display which holds a scent component.
- A booster device of an aroma display may include a plurality of fans, and the plurality of fans may be located at equal or substantially equal intervals around the aroma display in the housing.

FIG. 1 shows an appearance of anaroma display 50 that is secured in a booster device of an aroma display in accordance with a first preferred embodiment of the present invention. As shown inFIG. 1 , anaroma display 50 includes ahousing 60 that is a hexagonal or substantially hexagonal column with a central axis.FIG. 2 is an exploded perspective view of thearoma display 50, andFIG. 3 is a cross-sectional view taken along the line 3-3 inFIG. 1 of thearoma display 50. - Referring to
FIGS. 1 to 3 , thehousing 60 includes abase panel 82, abase body 84 located above thebase panel 82 and attached to thebase panel 82 by screws, for example, amiddle body 86 fitted to thebase body 84 from abovebase body 84, anupper body 88 fitted to the top of themiddle body 86, theupper body 88 including a cartridge loading section opening upward, which may be loaded with six aroma cartridges, and anupper panel 90 fitted to theupper body 88 to close the upper opening of theupper body 88. By removing theupper panel 90, the opening of theupper body 88 is exposed, and a user is able to access the aroma cartridge loading section to load or unload the loading section with aroma cartridges. - In the present preferred embodiment, the
upper body 88 includes a slightly rounded hexagonal cross-section, and thecartridge loading sections aroma cartridges aroma cartridge 138 is shown inFIG. 3 ) are provided inside theupper body 88. Accordingly, as shown inFIG. 2 , thearoma cartridges 130, . . . are included in theupper body 88. As an example, on a bottom surface of thearoma cartridge 132, an NFC tag 164 (seeFIG. 3 ) is attached, and at a nearby portion of theupper body 88, six NFC chips, for example,NFC chip 182 that is able to wirelessly communicate with theNFC tag 164, are provided. Thearoma display 50 has a hexagonal or substantially hexagonal column shape including an upper surface, a bottom surface and a side surface, with a central axis. - On a side surface of the
base body 84, ascrew hole 92 is provided as shown inFIGS. 1 to 3 , to which a tripod may be screwed in. Thescrew hole 92 may meet a specific standard to fit a tripod for a camera or the like. - Referring to
FIG. 2 , thebase body 84 includes a control board including a communication device mounted thereon to wirelessly communicate to/from an exterior of thearoma display 50, and control circuitry to drive micro blowers, which will be described later, and a battery as the power source thereof. Between themiddle body 86 and theupper body 88, anNFC chip stage 102 is provided, on which NFC chips 182 and the like communicating withNFC tags 164 provided at the bottoms ofaroma cartridges 130 are mounted. Further, on thebase panel 82, a plurality of small holes are provided to take in air to generate power to blow out scented air from thearoma cartridges 130. Afilter 94 is provided between thebase panel 82 and thebase body 84 to filter out dust from the introduced air. - NFC tags 164 of the
aroma cartridges 130, store ID codes of the scents included inrespective aroma cartridges 130. When thearoma display 50 is loaded with thearoma cartridges 130, NFC tags 164 communicate withcorresponding NFC chips 182 and transmit ID codes of the scents included in thearoma cartridges 130 to NFC chips 182.NFC chips 182 transmit these ID codes to an external PC or the like through wireless communication. Accordingly, the external PC or the like recognizes the ID codes of respective scents of thearoma cartridges 130 included in thearoma display 50, and the external PC or the like is able to thecontrol aroma display 50 to emit scents in accordance with a program. - Referring to
FIGS. 1 to 3 , at a central portion of anupper panel 90 of thehousing 60, anopening section 64 is provided. Particularly with reference toFIGS. 1 and 3 , at the center of theopening section 64, anopening 68 is provided, from which scent-free air from an air emission mechanism included in thehousing 60 is emitted, and around this opening, sixopenings 70, are provided, from which scents are emitted from sixaroma cartridges 130, included in thehousing 60. - As described above, the
aroma display 50 can be mounted on a tripod for a camera. By mounting thearoma display 50 on a small tripod that can be placed on one's desk, thearoma display 50 is able to be placed by the side of a PC, for example, with theopening section 64 of thearoma display 50 positioned very close to and directed to the user's face. Accordingly, predetermined scents are able to be easily transmitted to the user. - A
micro USB connector 66 is provided on a side surface of thehousing 60. In this preferred embodiment, aconnector 66 feeds power to thearoma display 50 through a USB cable and charges a built-in battery of thearoma display 50. The USB cable does not provide external communication for the circuitries in thearoma display 50. The circuitry inside thearoma display 50 exchanges data with an external device or the like via wireless communication. Accordingly, the inner circuitry of thearoma display 50 may perform data communication via wired communication by the USB cable. - Particularly referring to
FIG. 3 , at a portion of the lower surface ofupper body 88 which is above theNFC chip stage 102, amicro blower 184 defining a mechanism to emit scent-free air is fixed. Mechanisms including amicro blower 184 to feed air to an interior of thearoma cartridges 130 will be described later. - Referring to
FIG. 2 , theupper body 88 has a substantially hexagonal cross-section as described above. The inner space of theupper body 88 is divided into, for example, six aromacartridge loading sections aroma cartridges 130 are respectively inserted into thecartridge loading sections 110. - Referring to
FIG. 3 , as an example, thearoma cartridge 132 includes a triangular or substantially triangular prism housing of which a horizontal cross-section is a regular triangle or substantially a regular triangle. At a portion of the upper surface of the housing which faces theopening section 64 when the cartridge loading section is loaded with the aroma cartridge, anopening 160 is provided, which is connected to a hollow space inside the housing ofaroma cartridge 132 to emit scented air from the scent source sealed in the housing. At the portion of a side surface which is in contact with an inner surface of theupper body 88, anair feeding opening 158 is provided to feed air from an exteriormicro blower 234 to the interior ofcartridge 132. On the lower surface of thearoma cartridge 132, anNFC tag 164 is attached, for example, by a sticker, for near-field communication with anNFC chip 182. - At a portion of the inner side surface of the
upper body 88 at which theair feeding opening 158 for feeding air into the aroma cartridge is positioned whenrespective cartridges 130 are included in thecartridge loading sections 110, themicro blower 234 for feeding air intoair feeding opening 158 is provided. By driving themicro blower 234, air is fed to the interior of thearoma cartridge 132 and from theopening 160 for emitting scent of thearoma cartridge 132 positioned near the center, scented air is emitted to an exterior of thearoma display 50. - The
micro blower 234 has the same or similar structure as micro blowers disclosed in JP2014-092673A. Referring toFIG. 4 , specifically, themicro blower 234 has acase 250 with ablower chamber 252 as an inner space, and acover 254 with anozzle 270 provided on its top surface, attached to thecase 250 so that it covers the top surface of thecase 250 to close theblower chamber 252. Anair channel 256 is provided in thenozzle 270, and theair channel 256 opens into the upper portion of theblower chamber 252. - The
blower chamber 252 is divided into a upper portion and a lower portion by apartition plate 258. At a position immediately below theair channel 256 of thepartition plate 258, anopening 260 is provided and aligned with theair channel 256. - In the lower portion of the
blower chamber 252 divided by thepartition plate 258, adiaphragm 262 including a thin metal plate with spring resiliency and apiezoelectric element 264 bonded to the lower surface ofdiaphragm 262 are provided. By applying AC voltage to thepiezoelectric element 264, thediaphragm 262 vibrates up and down and emits air through theopening 260 to theblower chamber 252 and further through theair channel 256 to an exterior of themicro blower 234. By positioning themicro blower 234 inside theupper body 88 with thenozzle 270 positioned at the opening on the back side of the aroma cartridge, air is able to be introduced into thearoma cartridge 132 at a predetermined timing for a predetermined time period, and thus, scented air can be emitted from thearoma cartridge 132 and the like. Anair intake opening 266 is provided in acase 250, and the air from theintake opening 266 is fed through anair passageway 268 to theblower chamber 252. - Each of the aroma cartridges other than the
aroma cartridge 132 also includes amicro blower 234 to feed air into the aroma cartridge through the opening on the back side. By operating themicro blowers 234 independently, a predetermined aroma cartridge is able to be controlled to emit the scented air at a predetermined timing for a predetermined time period. Amicro blower 184 of the mechanism to emit scent-free air shown inFIG. 3 also includes the same or similar structure as this micro blower. Accordingly, the micro blower 185 is able to emit air at a predetermined timing for a predetermined time period from opening 68 shown inFIGS. 1 to 3 . Themicro blower 184 is larger than the othermicro blowers 234. Accordingly, the amount of air emitted from theopening 68 is far larger than themicro blowers 234, and themicro blower 184 is able to easily dissipate any scent lingering near theopening section 64 or carry a scent farther. - However, the
micro blower 184 feeds air by the vibration of a piezoelectric element, as shown inFIG. 4 . While themicro blower 184 has a fast response with a low level noise, the amount of air that is able to be fed from themicro blower 184 is structurally limited. Therefore, in order to spread a scent from the aroma cartridge to a wide space or to carry a scent afar, the air from themicro blower 184 on its own is insufficient. Though themicro blower 184 may be replaced with a larger fan, including a larger fan may generate increased acoustic noise when generating air flow of a certain volume, in contrast to a quiet operation comparable to themicro blower 184. - Therefore, a first preferred embodiment of the present invention includes a booster that includes a fan and surrounds the
aroma display 50 to spread a scent from thearoma display 50 far and wide or to quickly dissipate the scent. -
FIG. 5 shows an appearance of abooster 300 in accordance with the first preferred embodiment of the present invention, andFIG. 6 is an exploded perspective view thereof.FIG. 7 is a cross-sectional view taken along the line 7-7 of thebooster 300 shown inFIG. 5 .FIG. 8 is a cross-sectional view taken along the line 8-8 of an upper case of thebooster 300 shown inFIG. 7 . - Referring to
FIGS. 5 to 8 , thebooster 300 includes acolumnar housing 310 of a circular or substantially circular cross-section with a central axis, in which thearoma display 50 is included. Thehousing 310 includes alower case 320 provided with afan 326 therein and including acontainer portion 336 in which a lower portion of thearoma display 50 is provided, anupper case 322 attached to an upper portion of thelower case 320 and including acontainer portion 338 in which an upper portion of thearoma display 50 is provided, and aconical cap 324 including a circular or substantially circular cross-section attached to an upper portion of theupper case 322 where the circle diameter becomes smaller as a function of the distance fromupper case 322. Acap 324 is open at upper and lower ends. The shape of thecap 324, as will be described later, squeezes the air flow generated by thefan 326 at the upper portion of theupper case 322 and thus to increase the velocity of air flow. - A
partition 332 including a hexagonal or substantially hexagonal cross section defining acontainer portion 336 and holding side surfaces of thearoma display 50 is provided in thelower case 320. Thepartition 332 is fixed to an interior of thelower case 320 by aconnector 340 that couples the lower half of each corner of the hexagon with the inner surface of thelower case 320. As shown inFIG. 8 , each of thearoma display 50 and thehousing 310 has a central axis, and thepartition 332 holds thearoma display 50 with the central axis of thearoma display 50 and the central axis of thehousing 310 parallel or substantially parallel to and aligned with each other. - A
board structure 328, in which acontrol board 330 is provided, is located at a portion on an outer periphery of thelower case 320. As shown inFIG. 7 , thepartition 332 includes acylindrical portion 350 opened at upper and lower ends, with a size and shape that fits and holds thearoma display 50 therein, and aconical section 352 extending downward from the lower opening of thecylindrical portion 350, including a conical shape opened at upper and lower ends, to divide the air flow from thefan 326 to an interior and an exterior of thecylindrical portion 350. Theconical section 352 includes outer and inner side surfaces 530 and 532 and anopening 354 at a lower end. A cross-section of thepartition 332 has a shape and size such that thearoma display 50 fits an interior of thepartition 332. Theconical section 352 is tapered with its inner diameter becoming smaller downward and, therefore, thearoma display 50 is supported by theconical section 352 at a boundary between the lower end of thecylindrical portion 350 and the upper end of theconical section 352 and fixed inside thehousing 310. Here, the central axis of thearoma display 50 is aligned with the central axis of thehousing 310. - The
upper case 322 also includes apartition 334 defining thecontainer portion 338. Referring toFIGS. 7 and 8 , a cross-section of thepartition 334 has a hexagonal shape that fits the housing of thearoma display 50. A height of theupper case 322 to make, as is shown inFIG. 7 , the top position ofaroma display 50 even or substantially even with the upper end of thepartition 332 when thearoma display 50 is included in thehousing 310. Upper ends of sides corresponding to respective vertexes of the hexagon of thepartition 334 are connected to the inner surface of anupper case 322 by astructure 340. As can be particularly well seen fromFIG. 8 , between the outer surface of thepartition 334 and the inner surface of theupper case 322,air passages 384 are provided, which will be described later. - A
lower case 320 includes abottom plate 356 with a plurality of air inlets 358-360 to intake air. On thebottom plate 356, afan 326 is mounted. Thefan 326 is adapted to take air in from the air inlets 358-360 provided in thebottom plate 356, and to generate air flow in the direction of thearoma display 50 in thehousing 310. In the present preferred embodiment, the diameter of thefan 326 is larger than the inner diameter of theopening 354. A space is provided between the lower end of theconical section 352 and the upper end of thefan 326. In the present preferred embodiment, thefan 326 is driven by a DC-driven motor, and a maximum air flow rate of the fan is larger than a maximum air flow rate of themicro blower 184 that defines the air emission mechanism of thearoma display 50. Thefan 326 spreads far and wide the scent emitted from thearoma display 50 or quickly dissipates any scent lingering rather widely around thebooster 300. Therefore, the maximum air flow rate of thefan 326 is preferably far larger than the maximum air flow rate of themicro blower 184, for example. As an example, the maximum air flow offan 326 is preferably about 5 times, more preferably about 10 times, and further preferably about 50 times or more of the maximum air flow rate of themicro blower 184. Accordingly, the air flow rate of thefan 326 is preferably adjustable, for example. If the size of thefan 326 is too large, thebooster 300 becomes less portable and, therefore, the size of thefan 326 is limited by itself. Thefan 326 is provided inside thebooster 300. Accordingly, noise generated by operation of thefan 326 is able to be reduced. - Particularly referring to
FIG. 7 , in thebooster 300 including the above-described structure, the interior of thehousing 310 is divided, bypartitions inner space 380 holding thearoma display 50 andair passages aroma display 50, and joined at the portion of thecap 324. A plurality of openings are also provided at the bottom portion of thearoma display 50, and themicro blower 184 and the like of thearoma display 50 take air in fromspace 380 and uses it to emit scent from an aroma cartridge. Anair passage 382 is defined by the outer side surface of theconical section 352 and the inner side surface of thelower case 320. Anair passage 384 is a channel further downstream of theair passage 382 and, as shown inFIGS. 7 and 8 , theair passage 384 is defined by the outer side surface of thepartition 334 and the inner side surface of theupper case 322. Cross sections of theair passages aroma display 50, accelerating air flow at this portion. - The
cap 324 is detachable from theupper case 322. By removing thecap 324 from theupper case 322, thearoma display 50 can be removed from thebooster 300. Thearoma display 50 can be mounted on thebooster 300 by the reverse procedure. If theupper case 322 is made detachable fromlower case 320, attachment/detachment of thearoma display 50 becomes easier. - The
control board 330 is connected by a cable, not shown, to aconnector 66 and thefan 326 of thearoma display 50, feeding power to various electronic components in thearoma display 50 and thebooster 300. Further, thecontrol board 330 drives thefan 326 in accordance with an external control signal. In the present preferred embodiment, thearoma display 50 performs wireless communication, and thearoma display 50 is able to directly communicate with an external control device. The present invention, however, is not limited to the structure and operation described above. Thecontrol board 330 may transmit a control signal to the interior of thearoma display 50 through theconnector 66, or thecontrol board 330 may relay an output signal from thearoma display 50 to an external control device. - The
aroma display 50 and thebooster 300 described above operate as described below. - First, a user inserts necessary aroma cartridges into the
aroma display 50. The user removes thecap 324 from thebooster 300 and puts thearoma display 50 intohousing 310.FIG. 7 shows a cross section at this time of thebooster 300. - For example, a scenario may be provided for a movie reproduced on a PC, for example, to emit a specific scent identified by the identifier at a specific scene for a specific time period in synchronization with the movie. Then the PC reads the scenario and reproduces the scenario in synchronization with the movie. Specifically, the PC transmits a command to the wireless communication device of the
aroma display 50 and a specific scent is emitted from the aroma cartridge with the designated identifier at the timing designated by the scenario. Receiving the command, the wireless communication device applies AC voltage at the designated timing for the designated time period to themicro blower 234 of the cartridge loading section loaded with the designated scent. Accordingly, the designated scent is emitted from thearoma display 50 at the timing and for the duration as designated by the scenario. - The
micro blower 184 inside thearoma display 50 or thefan 326 in thehousing 310 may be controlled to be operated simultaneously with the emission of a scent. When themicro blower 184 is in operation, scent-free air is emitted to an exterior of thearoma display 50 from theopening 68 shown inFIGS. 1 and 3 . Together with this air flow, a scent from an aroma cartridge flows out fromcap 324 of thebooster 300. Accordingly, the user is able to observe the scent. In this case, however, the air flow generated by themicro blower 184 is weak and does not reach very far. Therefore, the scent is observed only in a close vicinity of thebooster 300. -
FIG. 9 shows air flow in thebooster 300 when thefan 326 is driven and themicro blower 184 is not driven. Referring toFIG. 9 , the air flow generated by thefan 326 is represented by white arrows, and the flow of scented air emitted by thearoma display 50 is represented by hatched arrows. Referring toFIG. 9 , thefan 326 takes in air and, through inlets 358-360 provided in thebottom plate 356, air is introduced to the interior of thehousing 310. Since the interior of theconical section 352 is closed by thearoma display 50, the air flow generated by thefan 326 goes toward the ring-shapedair passage 382. This air flow is accelerated through theair passages aroma display 50 and fed to thecap 324. The scent let out from the tip end of thearoma display 50 is emitted from thehousing 310 with velocity far higher than that caused by themicro blower 184, because of the air flow that has passed through theair passages - When the scent emitted from the
housing 310 is to be dissipated, the operation of various components is the same as or similar to when the scent is emitted, except that no scent is emitted from thearoma display 50. By emitting scent-free air to an exterior of thebooster 300 using thefan 326, not only the scent lingering near thebooster 300 but also the scent lingering considerably far is able to be quickly dissipated and blown away. Thus, the scent can be dissipated powerfully, and the possibility of unintentionally mixing with the next emitted scent is reduced. - When the
micro blower 184 is used, the air flow is weak and, therefore, only the scent lingering in the vicinity of thebooster 300 is able to be dissipated. - As described above, by the present preferred embodiment, the scent generated by the
aroma display 50 can be carried far and wide by using thefan 326. Further, the scent lingering in a wide range is able to be quickly dissipated. In addition, only the scent-free air is able to be emitted to a far distance. Accordingly, a scent is able to be emitted throughout a wide area and the mixing of scents is able to be prevented when the scents are switched. - When the
aroma display 50 and thebooster 300 are operated with a PC on one's desktop, it is unnecessary to operate thefan 326. Operation of themicro blower 184 is sufficient to personally enjoy a program with scents. - Further, according to this preferred embodiment, the
aroma display 50 is able to be freely be attached to/detached from thebooster 300. Therefore, for example, a plurality of the aroma displays 50 loaded with different aroma cartridges may be switched easily for use. Further, thearoma display 50 is able to be removed from thebooster 300, and thearoma display 50 may be operated by itself. - The
aroma display 50 in accordance with the first preferred embodiment described above provides emission of a scent to a wider space or dissipation of a scent from a wider space as compared with a conventional aroma display. Accordingly, operation of thearoma display 50 is able to be widened from personal use to more general use by a larger number of people. However, further improvements may be provided to let users more fully enjoy the scents. - In a real life setting, a scent is experienced not only by olfaction or sense of smell. In most cases, a scent is experienced with temperature. As an example, when one takes a sip of coffee, the aroma of coffee is experienced with its warmth. On the contrary, one experiences the scent of plants and trees with coolness in morning winds in the grass or in the forest.
- A second preferred embodiment of the present invention has provides only the function of emitting scents but also a function of heating or cooling the air containing scent, fit for the scene when the scent is presented.

FIG. 10 shows an appearance of abooster 400 for an aroma display in accordance with the second preferred embodiment.FIG. 11 is an exploded perspective view ofbooster 400.FIG. 12 is a cross-sectional view taken along the line 12-12 ofFIG. 10 . Referring toFIGS. 10 to 12 ,booster 400 includes ahousing 410, of which appearance is different from that ofhousing 310 in accordance with the first preferred embodiment. Thehousing 410 includes alower case 430 provided with afan 326 therein and including a container portion in which a lower portion of thearoma display 50 is placed, and including threeheat exchangers heat exchanger 424 is not shown inFIG. 10 ) in addition to theboard structure 328 on its periphery, anupper case 322 attached to the upper portion of thelower case 430, and acap 324 attached to the upper portion of theupper case 322. - Three
heat exchangers FIG. 12 , as an example, theheat exchanger 422 includes a plate-shapedPeltier module 491 with a Peltier element, provided at anopening 510 opened on a side surface of thelower case 320 with the heat absorbing (heat radiating) side surface facing theair passage 382 outside theconical section 352, aheat sink 492 attached to the heat radiating (heat absorbing) side surface of thePeltier module 491, and an overhangingportion 490 provided above theopening 510 protruding like a visor and covering the upper surface of theheat sink 492. Similarly, theheat exchanger 420 includes an overhangingportion 480, aPeltier module 481 and aheat sink 482. Theheat exchanger 424 includes an overhangingstructure 500, aPeltier module 501 and aheat sink 502. - The
Peltier module 491 is a plate-shaped semiconductor device and when a DC in a predetermined direction is applied, a heat absorbing surface of thePeltier module 491 cools an object that is in touch with the surface and radiates heat to a heat radiating surface of thePeltier module 491. When the direction of current is reversed, the heat absorbing and radiating surfaces are switched. In other words, thePeltier module 491 has a heat exchanging function. The width of thePeltier module 491 is equal or substantially equal to the width ofopening 510, and the upper edge of thePeltier module 491 is in air-tight contact with an upper edge of theopening 510. ThePeltier module 491 is attached to the lower case 320 a lower edge of thePeltier module 491 is positioned farther in from the side surface of thelower case 320. Therefore, the air flow generated by thefan 326 is split by thePeltier module 491 to the two sides thereof. - A
heater 460 to heat air that passes through theair passage 384 is provided in theupper case 322. Theheater 460 includes a cylindricalouter heat insulator 472 provided to be in contact with an inner surface of theupper case 322, a cylindricalinner heat insulator 474 provided to be in contact with an outer side surface of thecylindrical portion 350, and anichrome wire 470 wound a number of times around theinner heat insulator 474, provided between the outer andinner heat insulators nichrome wire 470 generates heat when a current is passed therethrough. Theinner heat insulator 474 protects scent sources in thearoma display 50 from the heated or cooled air in theair passage 384. Scent generating characteristics of scent sources change when scent sources are heated or cooled. Therefore, theinner heat insulator 474 is provided. Theinner heat insulator 474 may be provided at a position and range to protect from heating and cooling at least the portion of the aroma display at which scent sources are positioned. - In the
board structure 328, in place of thecontrol board 330 of the first preferred embodiment, acontrol board 462 is provided, which controls thePeltier module 491 and thenichrome wire 470 in addition to the function ofcontrol board 330. - Except for the above structure and operation, the
booster 400 includes the same or similar structure as that of thebooster 300 in accordance with the first preferred embodiment. When the direction of current is reversed, the heat radiating surface and the cooling surface of thePeltier module 491 are switched. Therefore, thebooster 400 is able to heat the air by reversing the direction of current fed to the Peltier module, rather than heating the air by using the nichrome wire. In that case, thenichrome wire 470 is unnecessary. Further, both thePeltier module 491 and thenichrome wire 470 may be operated to preheat the air by thePeltier module 491 and additionally heat the air by thenichrome wire 470. Such operation is able to be implemented by controlling signals or currents applied externally to thebooster 400. - The operation of the
booster 400 is the same as or similar to the operation of thebooster 300 in accordance with the first preferred embodiment. Thebooster 400 is different from thebooster 300 in that thebooster 400 is able to heat or cool the air generated by thefan 326 and passing through theair passages -
FIG. 13 shows air flow when thebooster 400 is in operation. InFIG. 13 , white arrows indicate the flow of air generated by thefan 326, and hatched arrows indicate the flow of scented air emitted from thearoma display 50.FIG. 14 shows, in enlargement, the portion ofFIG. 13 indicated byreference numeral 14. The flow of air in thebooster 400 is the same as or similar to the flow of air in thebooster 300 in accordance with the first preferred embodiment. What is different is that the air passing through theair passages - Particularly with reference to
FIG. 14 , a portion of the air generated by thefan 326 will be anair flow 550 that flows through theair passage 382 between theconical section 352 and theheat absorbing surface 562 of thePeltier module 491. Theair flow 550 is deprived of its heat by theheat absorbing surface 562 and cooled. Another portion of air generated by thefan 326 is anair flow 552 split from theair flow 550 by thePeltier module 491 and guided to the side of theheat radiating surface 560 of thePeltier module 491, which air flow deprives theheat radiating surface 560 of heat and passes through theheat sink 492, to be discharged outside from an opening of theheat sink 492. - As an example, by feeding DC to the
Peltier module 491 while driving thefan 326, the air flowing through theair passages aroma display 50 is able to be carried and spread with cold air. For example, while beautiful scenery of a mountain in a fresh morning is displayed on a PC screen, cold air with a fresh scent is spread, and a user will have a highly realistic sensation of a morning in the mountain. A portion of the air flow from thefan 326 is guided by thePeltier module 491 to the side of theheat sink 492, deprives the radiatingsurface 560 of heat by theheat sink 492, and dissipates the heat into the surrounding air. Accordingly, thePeltier module 491 is able to be efficiently operated. - Alternatively, the air flowing through the
air passages nichrome wire 470 without feeding any current to thePeltier module 491. For example, when a scene of pouring coffee is to be displayed on a PC as described above, the air is heated by feeding current to thenichrome wire 470 and a scent of coffee emitted from thearoma display 50 is carried with heated air. Accordingly, the scent of coffee spreads with warm air and the user is able to observe the realistic sense of tasting a cup of coffee. - As described above, by the
booster 400 in accordance with the present preferred embodiment, in addition to simply spreading a scent, dissipating a scent at a predetermined timing, or switching scents, the temperature of air carrying the scent is able to be adjusted in accordance with the scent. Accordingly, communication by scents is able to have a stronger effect. If heat only generated by thenichrome wire 470 is not sufficient, the current applied to thePeltier module 491 may be reversed to preheat the air passing through thechannel 384 and thus to increase the heating of the air. If thePeltier module 491 provides sufficient heating and cooling capacity, thenichrome wire 470 may be omitted. - The present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the preferred embodiments above. For example, in the preferred embodiments described above, the cross-sectional shape of the
aroma display 50 is hexagonal or substantially hexagonal and may be loaded with up to six aroma cartridges, for example. However, the shape of thearoma display 50 is not limited to a hexagon. The cross-sectional shape of thearoma display 50 may be determined independent of the number of the aroma cartridges to be included therein, and the cross-sectional shape of thearoma display 50 may include a shape of which number of corners match the number of cartridges to be included. - Further, in the preferred embodiments above, the
aroma display 50 is detachable from thebooster aroma display 50 may be removed from thebooster aroma display 50 is operated by itself, it is able to be operated personally on one's desktop, similar to a known aroma display.
