Description

TECHNICAL FIELD The present invention relates to an aroma transmission method and an aroma transmission device using an air cannon.

A technique is known in which scent-filled vortex rings are ejected from an air cannon to deliver scent to a target. This technology has the advantage of being able to present the intended amount of the intended scent to the target person at a predetermined timing from a remote location. On the other hand, since the fragrance is carried on the flying vortex ring, the fragrance is localized in a narrow area (vortex ring), and there is a problem that it is difficult for the target person to smell the fragrance. If the vortex ring does not touch the subject's nose area, the subject cannot perceive the scent.
On the other hand, Patent Literature 1 discloses a method of presenting a scent to a subject's nose by combining a device for measuring the position of the subject's nose and an air cannon. Further, Patent Document 2 discloses a device that causes two vortex rings to collide in front of a target person, diffuses scent, and supplies an aromatic component to the target person.

JP-A-2004-81851 JP 2010-22577 A

However, in the method according to the prior art document, while the ease of smelling the scent was improved, it required a device for measuring the nose position and two air cannons, which was a factor in complicating the device. . In addition, the vortex ring spreads widely, and the subject can only inhale a small part of the perfume in the vortex ring, and the perceived scent may be weak. Furthermore, if the flight speed of the vortex ring is too fast, the target person feels discomfort due to the wind pressure.
As a result of diligent studies, the present inventors set the structure of the air cannon, the flight speed of the vortex ring, the positional relationship between the air cannon and the subject, etc. within the optimal numerical range after making the vortex ring containing the scent visible. We have previously filed a patent application (Japanese Patent Application No. 2016-180026). However, in the previous invention, the distance between the ejection port of the air cannon and the target person is specified to be 1 m or more and 3 m or less, and it could not be applied when the distance is less than 1 m. Therefore, the present inventors continued to study and found the optimum numerical range applicable when the distance is less than 1 m. That is, the present invention uses a simple device configured with an air gun, so that even if the receiver, who is the target person who feels the scent, is at a distance of less than 1 m from the air gun, it is easy to smell without discomfort.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic diagram for demonstrating the fragrance transmission method and apparatus of 1st Embodiment of this invention. It is a figure which illustrates typically the cross section of the fragrance transmission apparatus shown in FIG. It is a figure which illustrates typically the cross section of the fragrance transmission device of 2nd Embodiment of this invention. It is a figure explaining typically the cross section of the aroma transmission apparatus concerning the experimental device corresponding to 2nd Embodiment of this invention.

The scent transmission method of the present invention will be described in detail below.
The present invention is a method of transmitting a scent to a recipient by ejecting a vortex ring that contains the scent and that is made visible by containing minute droplets from an air cannon. Then, a visible vortex ring containing microdroplets is shot with a diameter of 1.5 cm or more and 5 cm or less toward the recipient who is at a distance of 0.2 m or more and less than 1 m from the air cannon's ejection port. Eject from the exit at a flight speed of 0.3 m/s or more and 1 m/s or less.

(aroma)
Fragrance is vaporized or microparticulated aerosol of perfume or perfume dissolved in solvent. The fragrance can also contain moisture, which is vaporized or atomized water, if desired. From the viewpoint of preventing sedimentation due to gravity, the diameter of the microparticles is preferably 20 μm or less.
As the fragrance, known fragrances can be used without particular limitation. For example, natural fragrances extracted from natural products such as peppermint oil, synthetic fragrances such as limonene, and two or more known fragrances mixed in an appropriate ratio. Examples of perfumes obtained include perfumes that are solid at room temperature and have sublimation properties, such as menthol. Solvents include, but are not limited to, ethanol, propylene glycol, dipropylene glycol, butylene glycol, triethyl citrate, 3-methoxy-3-methyl-1-butanol, and tripropylene glycol methyl ether. do not have. Ethanol is preferably used because of its ease of handling.

(Micro droplet)
Microdroplets are fine particles of liquid, and are included in the vortex ring together with the scent, making the vortex ring visible. Since the microdroplets scatter visible light, the vortex rings become cloudy and visible. This allows the recipient to visually recognize the vortex ring, making it easier to smell the scent. The diameter of the fine droplets for this purpose is preferably 1 μm or more and 20 μm or less. If the diameter is smaller than 1 μm, the visible light scattering ability per microdroplet is lowered, and the visibility is lowered. If the diameter is larger than 20 μm, it tends to settle due to gravity. In addition, the number of microdroplets that can be filled per unit volume is reduced, the amount of scattering of visible light is reduced, and visibility is reduced.
Examples of liquids that can be used as raw materials for microdroplets include glycols such as propylene glycol, tripropylene glycol and 1,3-butylene glycol, organic solvents such as glycerin, water, and solvents in which multiple types of these are mixed. . Propylene glycol is preferably used because it has little odor and is easy to handle.

In the present invention, it is particularly preferred that the fragrance comprises fine particles of fragrance or fragrance dissolved in a solvent and moisture, and that the fragrance is contained in the vortex ring together with microdroplets containing propylene glycol as a main component. A major component means a component having the largest weight ratio. The perfume can be contained in the vortex ring at a higher concentration by using the finely divided perfume than by using the vaporized perfume. Moreover, it is possible to prevent the vaporized flavor from being absorbed and diluted by the microdroplets containing propylene glycol as a main component. Also, it is preferable that the moisture be composed of fine particles of water. The use of finely divided water rather than the use of vaporized water for humidity can suppress the vaporized water from being absorbed and diluted by microdroplets containing propylene glycol as a main component. As a result, it becomes easier for the recipient to perceive the scent.
Alternatively, the microdroplets can be composed of a liquid containing water as a main component, and the microdroplets can also serve as moisture. In this way, the fragrance can be composed of fine particles containing perfume and substantially free of water. At this time, it is preferable to irradiate the vortex ring with light in order to improve the visibility of the vortex ring.

(Distance from exit to target)
In the present invention, the distance from the ejection port of the air cannon to the target is 0.2 m or more and less than 1 m. A scent transmission method in which the distance is 1 m or more was disclosed in Japanese Patent Application No. 2016-180026 previously filed by the present inventors. The present invention is for cases where the distance is less than 1 m. However, the above distance is set to 0.2 m or more in order to secure a time margin for the person to receive the transmission to visually recognize the vortex ring and bring his/her nose closer. For the above reasons, the distance is preferably 0.3 m or more, more preferably 0.35 m or more.
Here, the distance from the exit port to the person being transmitted means the distance from the center of the opening of the exit port to the nose of the person being transmitted, or the shortest distance from the center of the opening of the exit port to the body surface of the person being transmitted. When either distance is 0.2 m or more and less than 1 m, the distance from the exit to the recipient is defined as 0.2 m or more and less than 1 m.

(flight speed)
The vortex ring is ejected from the injection port at a flight speed of 0.3 m/s or more and 1 m/s or less. Since the speed at which the vortex ring flies gradually decreases due to air resistance, the "flight speed" in the present invention is defined as the average speed when the vortex ring flies to a point 1 m away from the exit. Specifically, if the time it takes for the gas (head of the vortex ring) to exit the injection port and reach a point 1m ahead of the injection port is t seconds, the flight speed is calculated as 1/t [m/second]. be done.
Since the distance from the exit to the target is as short as 0.2 m or more and less than 1 m, the flight speed of the vortex ring is higher than that disclosed in Japanese Patent Application No. 2016-180026 (1 m per second or more and 2.5 m per second or less). slow down. In particular, by setting the speed to 1 m/s or less, the receiver does not feel discomfort due to the wind pressure. Moreover, by keeping the flight speed of the vortex ring to a low speed of 0.3 m/s or more and 1 m/s or less, the scent does not instantly pass through the person to whom it is transmitted, and the scent floats around the person to whom it is transmitted. This makes it easier for people to perceive scents. For the above reason, the flight speed of the vortex ring is preferably 0.9 m/s or less, more preferably 0.8 m/s or less. If the vortex ring travels at a speed of 0.3 m/s or more for a person at a distance of less than 1 m from the emission port, the vortex ring collapses before it reaches the person, due to air resistance. can be prevented from dissipating. For the above reasons, the flying speed of the vortex ring is preferably 0.35 m/s or more, more preferably 0.4 m/s or more.

(Injection amount)
Since the distance from the injection port to the person to be transmitted is as short as 0.2 m or more and less than 1 m, the volume of gas injected from the injection port (injection amount) is that disclosed in Japanese Patent Application No. 2016-180026 (350 cm ³ or more, 2500 cm ³ or less). The volume of the ejected gas is preferably 50 cm ³ or more from the viewpoint of securing the amount of fragrance carried by the vortex ring to a distance of 0.2 m or more and less than 1 m from the ejection port and facilitating the perception of the scent by the recipient. , 100 cm ³ or more. In addition, the volume of the ejected gas is preferably 500 cm ^{3 or less, more preferably 350 cm 3 or} less, from the viewpoint of preventing a decrease in fragrance transmission efficiency. If the volume of ejected gas is excessive, the amount of scent that escapes from the vortex ring during flight of the vortex ring increases, and the efficiency of scent transmission to the recipient decreases. In addition, the scent spreads over a wide area, and more of the scent dissipates without being inhaled by the person to whom it is transmitted, thus reducing the efficiency of transmitting the scent to the person to whom it is transmitted.

(Diameter of injection port)
The vortex ring is ejected from an ejection port (an ejection port 30 to be described later: see FIG. 1). The ejection port is an opening for ejecting the vortex ring from the air cannon to the outside, and has a substantially circular shape. The aperture (diameter) of the injection port is 1.5 cm or more and 5 cm or less. If the aperture is not a perfect circle, the diameter of the inscribed circle of the aperture is defined as the diameter of the injection port. Also, the center of the circle is defined as the aperture center.
As described above, the volume of gas injected from the injection port (injection amount) is smaller than that disclosed in Japanese Patent Application No. 2016-180026, so the diameter of the injection port is also the same as that disclosed in Japanese Patent Application No. 2016-180026 ( 4 cm or more and 15 cm or less). In particular, by setting the caliber (diameter) to 5 cm or less, it is possible to prevent the vortex ring from becoming large and the scent to spread over a wide range and become diluted, thereby facilitating the perception of the scent by the recipient. In addition, the fragrance that dissipates without being inhaled by the person to whom it is transmitted is reduced, and the efficiency of transmitting the fragrance to the person to whom it is transmitted can be improved. For the above reasons, the aperture (diameter) of the injection port is preferably 4.5 cm or less, more preferably 4 cm or less. In addition, since the caliber (diameter) is 1.5 cm or more, the amount of gas (amount of scent) that can be conveyed by the vortex ring to a distance of 0.2 m or more and less than 1 m from the injection port can be secured, and the recipient can perceive the scent. can be made easier. For the above reason, the aperture (diameter) of the injection port is preferably 2 cm or more, more preferably 2.5 cm or more.

(shopper)
The fragrance delivery method of the present invention is suitable for delivering fragrance to shoppers. In other words, the recipient of the fragrance transmission method of the present invention can be a shopper. As mentioned above, the air cannon used in the present invention has a relatively small ejection volume and ejection port diameter, so the air cannon can be made small enough to be installed in a store or storefront. Thus, for example, air cannons can be placed with the goods on or beside the goods shelf. Air cannons installed in this manner shoot vortex rings toward shoppers and transmit scents. Here, a shopper is defined as a person who visits a store for the purpose of buying, looking for, or looking at an article, or a companion of the visitor. At this time, if the scent of the vortex ring is the same as or similar to the scent of the product, it is possible to tell the shopper who is the recipient of the message what the scent of the product is. That is, the scent transmission method of the present invention involves installing an air cannon in a store or storefront, and transmitting the scent contained in the vortex ring to any product displayed in the store or storefront, or a scent similar to the product. , or a scent that represents the image of any product.

(Irradiation of light)
In the method of the present invention, the visibility of the vortex ring may be improved by irradiating the vortex ring with light such as white light or non-white light while the vortex ring is ejected from the exit port and flying to the recipient. . The use of non-white light colors the vortex rings and also imparts visual beauty. Non-white light is visible light that is not white light, and means light with a tint such as red, orange, yellow, yellow-green, green, blue, and purple. White light is light without color. Examples of light sources include light emitting diodes and laser diodes.

The vortex ring flying from the exit to the recipient may be illuminated continuously, intermittently, or temporarily. A plurality of colors of light may be applied at the same time, or the colors may be changed over time. There are no particular restrictions on the direction in which the light can be applied to the vortex rings.

In the scent transmission method of the present invention, a windshield can be provided for the purpose of preventing the flight of the vortex ring from being hindered by the surrounding air current.
In addition, it is preferable that the airflow be less than 0.3 m/s on the path along which the vortex ring flies from the exit to the recipient. Also, in order to improve the visibility of the vortex ring, a light shielding plate that weakens ambient light (illumination light from a fluorescent lamp or the like) may be used.

Next, the fragrance transfer device of the present invention will be described in detail below.
The aroma transmitting device of the present invention includes an aroma generator that imparts fragrance to a vortex ring, a microdroplet generator that includes microdroplets in the vortex ring and makes them visible, an injection port for ejecting the vortex ring, and an injection port. A pressurization device for ejecting a vortex ring from the ejection port, and a sensor for detecting whether or not the transmitted person is at any position within a range of 0.2 m or more and less than 1 m from the ejection port. The aperture is 1.5 cm or more and 5 cm or less, and the pressure device shoots a vortex ring at a flight speed of 0.3 m/s or more and 1 m/s or less based on the sensor detecting that the person being transmitted is at the above position. It is characterized by being ejected from the exit.
Alternatively, the aroma transfer device of the present invention comprises an aroma generator that imparts fragrance to a vortex ring, a microdroplet generator that includes microdroplets in the vortex ring to make them visible, and an injection port for ejecting the vortex ring. , a pressurizing device for ejecting the vortex ring from the injection port, and a launch switch for driving the pressurizing device to eject the vortex ring, the diameter of the injection port being 1.5 cm or more and 5 cm or less, The launch switch can be manually operated by the recipient from a distance of 0.2m or more and less than 1m from the ejection port, and the pressurization device ejects a vortex ring from the ejection port at a flight speed of 0.3m or more and 1m or less per second. characterized by

(fragrance generator)
The scent generator generates the aforementioned scent. A known method can be used to generate the fragrance, and for example, volatilization by heating, atomization by ultrasonic vibration, diffusion by air blowing, and the like can be used. For sublimable fragrances that are solid at room temperature, the fragrance can be generated by utilizing diffusion by air blowing.

(microdroplet generator)
A microdroplet generator generates the aforementioned microdroplets. A well-known method can be used to generate fine droplets, and examples thereof include volatilization by heating and atomization by ultrasonic vibration.

(Injection port)
The preferred aperture (diameter) for ejecting the vortex rings is as described above.

(Pressure device)
The pressurizing device ejects the vortex ring from the ejection port at the above-described predetermined flight speed. The flight speed of the vortex rings can be adjusted by the pressurizing speed of the pressurizing device. If the pressurization speed is increased, the flight speed of the vortex rings is increased, and if the pressurization speed is decreased, the flight speed of the vortex rings is decreased.

(sensor)
The sensor detects whether or not an object such as a person to be transmitted exists within a range of 0.2 m or more and less than 1 m from the exit. When the person to be transmitted approaches the scent transmission device and enters the range of 0.2 m or more and less than 1 m from the emission port, the sensor detects that the person to be transmitted exists within the range and drives the pressure device. to eject a vortex ring from the ejection port. Therefore, the flight distance of the vortex ring from the exit to the target is approximately 0.2 m or more and less than 1 m.
The sensor is located on the side of the fragrance transmission device where the injection port is provided, that is, the front side where the vortex ring is emitted, and within a range of 0.2 m or more and less than 1 m from the center of the opening of the injection port (hereinafter referred to as , "detectable position"), it is detected that the recipient is at that position. A known distance sensor can be used as the sensor. For example, an optical sensor using infrared rays or visible light, an ultrasonic sensor using ultrasonic waves, a pyroelectric infrared sensor, and the like can be mentioned.

(launch switch)
The scent delivery device may include a firing switch in addition to or alternatively to the sensor. The firing switch is a means for driving the pressurizing device and ejecting the vortex ring by accepting manual operation by a person or automatic operation by an output signal from the sensor. It is means for accepting automatic operations.
When the firing switch is automatically operated by a sensor, when the above sensor detects that the target is in a detectable position and outputs a signal indicating that, the firing switch accepts the output signal and automatically A vortex ring is ejected by driving the pressure device. In addition, when the transmission switch is manually operated by the transmissionee or a third party (operator) and a sensor is provided, the transmissionee or the third party (operator) operates the transmission switch ( When turned on), if the sensor detects that the target is at a detectable position, it is determined that the operation of the launch switch is valid and the vortex ring is ejected.

If the firing switch is manually operated by the recipient and is not equipped with a sensor, the firing switch is preferably located at a position where it can be operated from a distance of 0.2 m or more and less than 1 m from the ejection port. It is preferable that the emission switch is arranged on the side of the fragrance transfer device where the emission port is provided (on the left side in the example of FIG. 3, which will be described later). As a result, when the transmissible person reaches out and operates the firing switch, the transmissible person will face the front of the ejection port and be at a position of 0.2 m or more and less than 1 m from the ejection port. . Therefore, the distance that the vortex ring ejected from the ejection port flies to the target is about 0.2 m or more and less than 1 m.
When the belly button of the recipient is at least 0.2m and less than 1m from the center of the opening of the ejection port, and the firing switch can be operated by reaching out with the hand, etc., the firing switch is at least 0.2m from the ejection port, Defined as operable from a distance of less than 1 m.

(Outline of air cannon)
The scent transmitting device of the present invention is suitably used when transmitting a scent that is the same as or similar to the scent of a product to a recipient. At this time, it is preferable that the outer shape of the air cannon be a shape reminiscent of the container of the product. For this reason, the outer shape of the air cannon is preferably a container-like shape. As a result, the recipient smells the scent of the vortex ring while looking at the outer shape of the air cannon and remembering the product or its container, so that the product can be associated with the scent. In this way, the scent transfer device plays the role of a scent sample that impresses the recipient with the scent of the product. Furthermore, when the product is a product that is used by injecting a liquid formulation from the injection port of the container, it is preferable to provide the injection port at a position corresponding to the injection port. The ejection of the vortex ring reminds us of the injection of formulations in the product, and enhances the entertainment value.
A shape that mimics the container of the product means that a part or the whole of the outer shape of the air cannon has a shape similar to a part or the whole of the container of the product. It does not necessarily have to have a congruent shape, and may have a similar shape or a slightly deformed shape as long as the container can be imagined. In addition, it is preferable that the surface of the air cannon has the same color and design as the container of the product so as to facilitate recall.

(Light irradiation device)
The scent delivery device may comprise a light irradiation device. The light irradiation device irradiates the vortex ring with light, such as white light or non-white light, while the vortex ring is flying from the exit to the recipient, thereby improving the visibility of the vortex ring. The light irradiation device is composed of a light source such as a light emitting diode or a laser diode and a power supply for driving it.

A preferred first embodiment of the present invention will be described below with reference to the drawings. In addition, in all the drawings, the same components are denoted by the same reference numerals, and overlapping descriptions are omitted as appropriate. In addition, the above-mentioned (fragrance), (microdroplets), (distance from the ejection port to the recipient), (aperture aperture), (shopper), (flight speed), (ejection amount), ( Light irradiation), (fragrance generator), (microdroplet generator), (ejection port), (pressure device), (sensor), (fire switch), (outer shape of air cannon), (light irradiation device) ) are applied to the first embodiment as they are, and overlapping descriptions are omitted as appropriate.

<First embodiment>
1 and 2 are a schematic diagram (perspective view) showing the overall configuration of an aroma transfer device 10 according to a first embodiment of the present invention and a diagram schematically illustrating a cross section of the aroma transfer device 10, respectively. In FIG. 1, the outer shape of the aroma transfer device 10 is indicated by a thick solid line, and the internal structure thereof is indicated by a thin solid line. However, the aroma generator 41 and part of the pipes 44, 45 and 46 are indicated by dashed lines. In addition, in FIG. 2, hatching of a part of the internal structure of the aroma transmitting device 10 is omitted. The same applies to the fragrance transmission device 110 shown in FIG. 3 and the fragrance transmission device 210 shown in FIG.

The aroma transmitting device 10 includes an air gun 11 composed of a model portion 20 imitating a product container and a rectangular parallelepiped pedestal portion 21 . A recipient (not shown) smells the scent of the vortex ring 12 ejected in the direction of arrow D from the ejection port 30 of the air cannon 11 while looking at the model part 20 imitating the product container.

The inside of the model part 20 is hollow, and an injection port 30 and a vent 32 are provided in communication with the outside. The upper part inside the hollow model part 20 is used as a gas filling tank 40 . A pressurizing device 50 and a sensor 61 are accommodated in the lower part of the interior of the model section 20 . The pedestal portion 21 accommodates an aroma generator 41, a moisture generator 42, a microdroplet generator 43, and a driving device 60. As shown in FIG. Between the model part 20 and the pedestal part 21, a pipe 44 for sending the aroma generated by the aroma generator 41 into the gas-filled tank 40, and the moisture generated by the moisture generator 42 are supplied to the gas-filled tank 40. and a pipe 46 for sending microdroplets generated by the microdroplet generator 43 into the gas-filled tank 40 are connected.
The surface of the model part 20 has the same color and design as the product container. The pedestal portion 21 is formed of a light-shielding member whose interior cannot be seen through with the naked eye. The device 60 and the like are made invisible.

The model section 20 has a head section 26 and a cylindrical section 22 formed on the tip side thereof. The injection port 30 is formed at the tip of the tubular portion 22 of the model portion 20 . The model part 20 of this embodiment imitates a spray container, that is, the product that the model part 20 imagines is a liquid-filled spray that is used by grasping a lever and injecting a liquid formulation from the injection port of the container. is a container. The ejection port 30 is provided at a position corresponding to the ejection port of the container. The model section 20 also has a lever section 27 below the head section 26 . Thus, the ejection of the vortex ring 12 is reminiscent of the ejection of formulations on commercial products. However, since this lever portion 27 is intended to remind of a spray container and is not operated by gripping, it may be formed fixedly with respect to the head portion 26 . The injection port 30 is provided with a shutter 31 that opens only during the period of gas injection. By closing the outlet 30 with the shutter 31, it is possible to reduce the leakage of fragrance from the outlet 30 to the outside.

The gas-filled tank 40 holds air containing fragrance and microdroplets. Aroma is composed of perfume and, if necessary, water. Part of the gas held in the gas-filled tank 40 is ejected from the ejection port 30 in the direction of the arrow D to form the vortex ring 12 and propagate to the recipient.

The elastic membrane 51 is arranged so as to divide the cavity inside the model section 20 into two and forms the bottom surface of the gas-filled tank 40 . A fixed portion 28 (see FIG. 2) is formed at an intermediate height of the model portion 20, and the elastic membrane 51 is attached to the fixed portion 28. As shown in FIG. In FIG. 1, the illustration of the fixing portion 28 is omitted. Upper ends of the pipes 44 , 45 , 46 are open to the gas filling tank 40 .

The pressurizing device 50 pressurizes the gas in the gas filling tank 40 and ejects the gas from the injection port 30 to the outside. The ejected gas forms a vortex ring 12 . 1, the pressurizing device 50 is electrically driven by the driving device 60 to pull the elastic membrane 51 downward, ie, away from the injection port 30, through the detachable joints 52 and 53, and then the elastic membrane Release 51. For example, a magnetic material can be used for the joint 52 and an electromagnet can be used for the joint 53 . That is, the pressurizing device 50 pulls the elastic membrane 51 downward in a state where the joint portion 52 fixed to the elastic film 51 and the joint portion 53 fixed to the pressurizing device 50 are joined to each other, thereby stretching the elastic film 51 . . After that, when the joint between the joint portion 52 and the joint portion 53 is released and the elastic film 51 is released, the elastic film 51 contracts due to the elastic restoring force, and the gas is pressurized. The pressurizing device 50 is not limited to this, and any known device can be used without particular limitation. be done. When the elastic membrane 51 contracts, the inside of the gas-filled tank 40 is pressurized up to the head portion 26 and the cylindrical portion 22 . When the shutter 31 is open, the gas-filled tank 40 communicates with the outside only through the injection port 30. Therefore, when the gas inside the gas-filled tank 40 is pressurized, part of the gas is injected from the injection port 30. A vortex ring 12 is formed.
In the first embodiment, the pressurization speed of the pressurizing device 50 is adjusted so that the vortex ring 12 propagates at a flight speed of 0.3 m/s or more and 1 m/s or less, and the gas (vortex ring) is ejected.
If the surroundings of the pressurizing device 50 are airtight, pressurization of gas due to contraction of the elastic membrane 51 is hindered. The vent hole 32 is formed at a position on the rear surface 25 of the model part 20 that does not communicate with the gas-filled tank 40 . The opening has a substantially rectangular shape.

The aroma generator 41 is electrically driven by the driving device 60 to generate aroma and fill the gas filling tank 40 with the aroma. Fragrance is vaporized or atomized perfume or perfume dissolved in a solvent. The fragrance can also contain moisture, which is vaporized or atomized water, if desired.

The fragrance generator 41 generates fragrance from fragrance or fragrance dissolved in a solvent. A perfume or a perfume dissolved in a solvent is stored in a storage container (not shown) within the perfume generator 41 . A known method can be used to generate the fragrance, and for example, volatilization by heating, atomization by ultrasonic vibration, diffusion by air blowing, and the like can be used. Sublimable fragrances that are solid at room temperature can be stored in a storage container in the fragrance generator 41 in a solid state, and the fragrance can be generated by utilizing the diffusion by air blowing. The produced aroma is sent into the gas-filled tank 40 through the pipe 44 .
The aroma generator 41 may comprise a moisture generator 42 . The moisture generator 42 generates moisture and fills the gas filling tank 40 with the moisture. Moisture is water vaporized or atomized. Water is stored in a water reservoir (not shown) within the moisture generator 42 . An antimicrobial agent may be added to the water. Ethanol is preferably used as the antibacterial agent because it has little odor and is easy to handle.

A known method can be used to generate moisture, such as volatilization by heating and atomization by ultrasonic vibration. The generated moisture is sent into the gas-filled tank 40 through the pipe 45 . Incorporating the moisture generated in this way into the fragrance can alter the quality of the fragrance. In particular, from the viewpoint of changing the quality of the scent to a scent with a natural feeling close to the scent of natural products, it is preferable to set the relative humidity in the gas-filled tank 40 to 70% or higher.

The microdroplet generator 43 is electrically driven by the driving device 60 to generate microdroplets for making the vortex ring 12 visible and to fill the gas-filled tank 40 with the microdroplets. In a first embodiment, the vortex ring 12 contains microdroplets along with the scent, making the vortex ring 12 visible. Since the microdroplets scatter visible light, the vortex rings become cloudy and visible. A liquid that is a raw material for microdroplets is stored in a droplet storage container (not shown) in the microdroplet generator 43 . A well-known method can be used to generate fine droplets, and examples thereof include volatilization by heating and atomization by ultrasonic vibration. The generated minute droplets are sent into the gas-filled tank 40 through the pipe 46 .
In the first embodiment, the fragrance is adjusted in terms of the amount, composition, etc. so that the vortex ring 12 has the same or similar fragrance as the product. While looking at the model part 20 of the container of the product, the recipient smells the scent of the vortex ring 12 which becomes cloudy and becomes visible and flies, and can know what kind of scent the product has. The scent transmitting device of the present invention can play the role of a scent sample that impressively conveys the scent of a product to a person to whom it is transmitted in a store, a shop front, an event, or the like.

The driving device 60 is connected to the pressurizing device 50, the fragrance generating device 41, the moisture generating device 42, the minute droplet generating device 43, and the shutter 31 through an electric cable (not shown), and electrically controls and drives each device. , causes the above operation to be performed. When the scent transmitting device 10 is powered on (not shown), the driving device 60 closes the shutter 31, causes the pressure device 50 to pull the elastic membrane 51, and makes the elastic membrane 51 stand by in a stretched state. Then, the aroma generator 41, the moisture generator 42, and the microdroplet generator 43 generate aroma and microdroplets, and fill the gas filling tank 40 with them.

The aroma transfer device 10 of this embodiment has a discharge switch (not shown). The driving device 60 is connected to a firing switch, and when the firing switch is operated (turned on), the shutter 31 is opened, and at the same time, the joints 52 and 53 of the pressurizing device 50 are released and the elastic membrane 51 is opened. release the The elastic membrane 51 is contracted by an elastic restoring force, the gas is pressurized, and a vortex ring is ejected from the ejection port 30 . When the injection is completed, the driving device 60 closes the shutter 31, again causes the pressure device 50 to pull the elastic film 51, and waits while the elastic film 51 is stretched. Then, the aroma generator 41, the moisture generator 42, and the microdroplet generator 43 are used to generate the aroma and the microdroplets, and the gas filling tank 40 is filled with them. By repeating this operation, the aroma transfer device 10 repeatedly ejects the vortex ring 12 . The time interval from the operation of the ejection switch to the start of ejection of the vortex ring 12 can be set arbitrarily. For example, when an advertisement image of a product or the like is to be viewed by the person receiving the message through an image display device (not shown), the emission timing of the vortex ring 12 can be determined according to the contents of the image.

In addition, the scent transfer device 10 has a sensor 61 . A detection portion 62 of the sensor 61 is arranged on the front surface 24 of the model portion 20 (the surface where the injection port 30 is viewed from the front). A known distance sensor can be used for the sensor 61 . For example, an optical sensor using infrared rays or visible light, an ultrasonic sensor using ultrasonic waves, a pyroelectric infrared sensor, and the like can be mentioned. When the sensor 61 is an optical sensor or an infrared sensor, the detection unit 62 is a light receiving/emitting unit, and when the sensor 61 is an ultrasonic sensor, the detection unit 62 is an ultrasonic transmission/reception unit. The sensor 61 detects whether or not the person to be transmitted is at any position (detectable position) within a range of 0.2 m or more and less than 1 m from the exit 30, and detects that the person to be transmitted is at the detectable position. When detected, operate the launch switch (turn it on). As a result, the driving device 60 drives the pressure device 50 and the shutter 31 as described above, and the vortex ring 12 is ejected. The vortex ring 12 will be automatically fired without the recipient manually operating the firing switch. After a certain period of time has elapsed since the vortex ring was ejected, the sensor 61 again begins to detect whether or not the target is at the detectable position. (Do not operate the firing switch while detecting that there is no recipient). After that, this operation is repeated. The fixed time can be set arbitrarily, but it should be longer than the time required for the driving device 60 to fill the gas-filled tank 40 with the fragrance and the microdroplets.

The firing switch may be manually operated by the recipient or a third party. That is, the transmission target or a third party may operate (turn on) the ejection switch when he or she wishes to eject the vortex ring 12 . In this case, when the first condition that the sensor 61 detects that the person to be transmitted is in a detectable position and the second condition that the person to be transmitted or a third party operates the firing switch, the firing switch is activated. should be valid. In response, the driving device 60 ejects the vortex ring 12 . As a result, the aroma transmitting device 10 emits the vortex ring 12 toward the person to whom the scent is transmitted, who is at a distance of 0.2 m or more and less than 1 m from the emission port 30 .
There is no particular limitation on the timing before or after the timing when the sensor 61 detects the recipient and the timing when the firing switch receives the operation.
That is, regardless of whether or not the firing switch accepts the operation, the sensor 61 constantly detects whether or not the person being transmitted is at the detectable position, and when the sensor 61 detects the person being transmitted at the detectable position. (under the first condition), when the launch switch receives the operation (the second condition is met), the driving device 60 determines that the operation of the launch switch is valid and ejects the vortex ring 12. may In other words, when the sensor 61 detects that there is no recipient at the detectable position, that is, while the sensor 61 does not detect that the recipient is at the detectable position, the operation of the firing switch is invalidated. , the drive 60 does not eject the vortex ring 12 .
Alternatively, the sensor 61 is stopped until the launch switch accepts the operation, and when the launch switch accepts the operation (the second condition is established), the sensor 61 is activated, and the sensor 61 detects the recipient. The driving device 60 may eject the vortex ring 12 in response to what has been done (the first condition is satisfied). In this case, the power consumption can be reduced because the sensor 61 can be stopped until the firing switch receives the operation.

In the first embodiment, the visibility of the vortex ring 12 is improved by irradiating the vortex ring 12 with light from a light irradiation device (not shown) while the vortex ring 12 is flying from the exit 30 to the recipient. good too. The light source of the light irradiation device may be arranged inside the model section 20 or the pedestal section 21 , or may be arranged outside the model section 20 or the pedestal section 21 . Light irradiation is particularly effective when the microdroplets are mainly composed of water, and the visibility of the vortex ring 12 is greatly improved. Irradiation of light from the light irradiation device may be performed all the time regardless of the timing at which the vortex ring 12 is emitted, or may be performed only when the vortex ring 12 is emitted. In the former case, the illumination device continues to illuminate the flight path of the vortex ring 12 or a portion thereof. In the latter case, the light irradiation device is electrically connected to the driving device 60, and the driving device 60 drives the light irradiation device in conjunction with the operation of driving the pressurizing device 50 to eject the vortex ring 12. 12 may be irradiated with light. The light irradiation device may continuously irradiate the vortex ring 12 in flight with light, or may irradiate the vortex ring 12 in flight with light intermittently or temporarily.

According to the aroma transmitting device 10 of the first embodiment, the minute liquid droplets are included and made visible to the person being transmitted who is at a distance of 0.2 m or more and less than 1 m from the ejection port 30 of the air cannon 11. A scent transmission method can be implemented in which a vortex ring is ejected from an ejection port 30 having a diameter of 1.5 cm or more and 5 cm or less at a flight speed of 0.3 m/s or more and 1 m/s or less. By being at a distance of 0.2 m or more and less than 1 m from the injection port 30, the person to be transmitted becomes cloudy and can be visually recognized while looking at the model part 20 of the container of the product, and the vortex ring 12 that automatically flies away. You can smell the scent and know what the product smells like. In this way, the scent transfer device 10 can play the role of a scent sample that impressively conveys the scent of a product to a recipient in a store, storefront, event, or the like. Furthermore, the product is used by injecting a liquid formulation from the injection port of the container, and the injection port 30 is provided at a position on the model section 20 corresponding to the injection port. For this reason, the injection of the vortex ring 12 reminds us of the injection of the formulation in the product, and has a high entertainment value.

Tables 1, 2 and 3 show the evaluation of the intensity of the scent perceived by the recipient and the sensitivity of the scent (discomfort and ease of smelling) under multiple conditions using the scent transmitter 210 shown in FIG. This figure shows the experimental results. Here, the sensibility of the scent indicates whether or not the recipient is likely to perceive the scent of the vortex ring, and is an index indicating the presence or absence of discomfort due to the wind pressure of the vortex ring and the ease of smelling the scent of the vortex ring. The aroma transmission device 210 according to the experimental apparatus shown in FIG. 4 differs from the aroma transmission device 110 (see FIG. 3) of the second embodiment in that a manually operated firing switch 63 is provided on the same front surface 24 side as the ejection port 30. handle. In addition, this aroma transmitting device 210 has the following points: the model portion 20 is changed to a rectangular portion 23 in the shape of a rectangular parallelepiped; the injection port 30 can be replaced with one having a different diameter; It is different from the aroma transmission device 110 in that it is arranged in the position. Accompanying this change, the elastic film 51 is arranged parallel to the injection port 30 (the vertical direction in FIG. 4), and the direction in which the elastic film 51 is pulled by the pressurizing device 50 is changed to the horizontal direction. Also, the air vent 32 is arranged on the upper surface of the rectangular portion 23 , and the injection port 30 is provided substantially in the center of the front surface 24 of the rectangular portion 23 . Also, since the firing switch 63 is provided on the front surface 24 of the pedestal 21, it can be operated by the person being transmitted from a distance of 0.2 m or more and less than 1 m from the ejection port 30 by reaching out. The person to whom the transmission is made has his/her face facing the exit 30 and smells the scent of the vortex ring emitted in the direction of the arrow D.

In any of Tables 1 to 3, each of the experiments conducted under multiple conditions is identified by the notation A through P.
In Tables 1 to 3, the intensity of fragrance is expressed according to the following criteria.
◎ Perceives a strong scent ○ Perceives a scent △ Perceives a weak scent × Does not perceive a scent Perceptible weak odor, 3: easily perceivable odor, 4: strong odor, 5: strong odor. When it is 0 or more and less than 3.5, it is evaluated as ◯, and when it is 3.5 or more, it is evaluated as ⊚. These scores were obtained by averaging the numerical values obtained by repeating the 6-level odor intensity evaluation three times by each of the three recipients.
In addition, the sensibility of fragrance (discomfort and ease of smelling) is expressed by the following criteria.
○ Easy to perceive scent △ Able to perceive scent × Hard to perceive scent (3) The time to feel the scent is short (the scent passes instantly and is difficult to match with the intake). . In addition, when none of the above (1) to (3) was met, and (4) the vortex ring was wide and only a part of the vortex ring could be smelled, was evaluated as "Δ". When the scent was smelled without falling under any of the above (1) to (4), it was rated as "◯". These evaluations were repeated three times by each of the three recipients and evaluated as ◯, Δ, and ×, and the most frequent evaluation was taken as the final sensitivity (◯, Δ, ×). In addition, when the fragrance intensity was judged to be x, the symbol "-" was entered because the sensitivity to fragrance could not be evaluated.

Table 1 shows the results of an experiment in which the distance between the injection port and the person being transmitted is set as a parameter, the diameter of the injection port is 4 cm, the flight speed of the vortex ring is 0.6 m/s, and the volume of the injected gas is about 250 cm ³ . is a table showing The distance between the exit port and the recipient was 0.1 m in Experiment A, 0.3 m in Experiment B, 0.5 m in Experiment C, 1 m in Experiment D, and 1.5 m in Experiment E. Also, the perfume used was a fruity perfume, and moisture (water micronized by ultrasonic vibration) and microdroplets containing propylene glycol as the main component were added. In Experiment A, the distance between the recipient and the launch switch was too close, and in Experiment E, the distance was too long, making it difficult for the recipient to operate the launch switch, so a third party operated it.
According to the results shown in Table 1, the closer the distance between the emission port and the person being transmitted, the stronger the scent intensity. Since there was no time to visually recognize the coming vortex ring, the sensitivity to scent decreased. Under the conditions of Experiment B, Experiment C, and Experiment D, where the distance between the emission port and the recipient was 0.2 m to 1 m, it was found that the recipient could perceive the scent of the vortex ring relatively easily.

Table 2 shows the results of an experiment in which the flight speed of the vortex ring is set as a parameter, the distance between the injection port and the transmitted person is 0.5m, the diameter of the injection port is 4cm, and the volume of the injected gas is about ^250cm3 .

Also, the perfume used was a fruity perfume, and moisture (water micronized by ultrasonic vibration) and microdroplets containing propylene glycol as the main component were added.
According to the results shown in Table 2, in Experiment F in which the flight speed of the vortex ring was too slow, the vortex ring collapsed during flight and the intensity of the scent decreased. On the other hand, in Experiments J and K, in which the flight speed of the vortex ring was too fast, the subject felt uncomfortable due to the wind pressure, and the time during which they could perceive the scent was shortened. Under the conditions of Experiment G, Experiment H, and Experiment I in which the flight speed of the vortex ring was 0.3 m/s or more and 1 m/s or less, it was found that the recipient could relatively easily perceive the scent of the vortex ring.

Table 3 shows an experiment in which the diameter of the injection port is set as a parameter, the flight speed of the vortex ring is 0.6 m/s, the distance between the injection port and the recipient is 0.5 m, and the volume of the injected gas is about 250 ^cm3 . It is a table|surface which shows the result of. The diameter of the injection port was 1 cm for Experiment L, 2 cm for Experiment M, 3 cm for Experiment N, 5 cm for Experiment O, and 7 cm for Experiment P. Also, the perfume used was a fruity perfume, and moisture (water micronized by ultrasonic vibration) and microdroplets containing propylene glycol as the main component were added.
According to the results shown in Table 3, in Experiment L, where the diameter of the injection port is less than 1.5 cm, which is too small, the vortex ring can carry a small amount of aroma, and the intensity of the aroma is reduced. On the other hand, in Experiment P, in which the diameter of the injection port was too large, exceeding 5 cm, the fragrance spread and the sensitivity to the fragrance decreased. Under the conditions of Experiment M, Experiment N, and Experiment O, in which the diameter of the exit port was 1.5 cm or more and 5 cm or less, it was found that the recipient could relatively easily perceive the scent of the vortex ring.

From the above experimental results, according to the fragrance transmission method and the fragrance transmission device of the present invention, a vortex ring is ejected from an ejection port having a diameter of 1.5 cm or more and 5 cm or less at a flight speed of 0.3 m or more per second and 1 m or less per second. , it was found that a perceivable intensity of scent can be transmitted to a recipient at a distance of 0.2 m or more and less than 1 m from the outlet in a manner that the recipient feels comfortable and easily smelled.
