Description

TECHNICAL FIELD

[0001] The present invention relates to an olfactory emission device configured to emit a plurality of odors / fragrances in the region of or directed toward at least one nostril of an individual, comprising at least one fan unit and at least one motor, wherein a plurality of odor pads are provided / stored in a magazine and can be individually activated. Furthermore, the present invention relates to a method for emitting a plurality of odors / fragrances individually per individual in the region of or directed toward at least one nostril of the individual, wherein forced convection is generated by means of at least one fan unit, in particular by means of such an olfactory emission device.Last but not least, the present invention also relates to a computer program product for controlling / regulating such a method, as well as to the use of a specific type of magazine for specifying kinematics for a movement path for positioning each individual one of a plurality of odor pads to activate the corresponding odor pad at a designated activation point in the region of a flow path of a forced convection generated by at least one fan unit, in particular in such an olfactory emission device. In particular, the invention relates to an olfactory emission device and method according to the preamble of the respective independent claim. BACKGROUND OF THE INVENTION

[0002] There has long been a desire to expand and optimize sensory impressions, particularly when consuming media such as films, and in particular to make a more or less virtual experience seem even more real. This also includes measures that utilize olfactory perception, particularly in synchronization with audiovisual content. However, previous attempts to create devices and methods for providing scents to each individual have not yet been successful enough to be considered usable. Rather, the major challenge, particularly for olfactory messages, is to activate or utilize this level of perception for as short a time window as possible and then to neutralize it again as quickly as possible - compared to audiovisual impressions, this is much more difficult for scents and smells that spread throughout a room.For example, it remains difficult to establish scent cinemas or generate enthusiasm for them among end consumers. This is due in no small part to inadequate technological framework conditions.

[0003] As an example, publication EP 3 226 981 B1 can be mentioned, which describes a device for providing a continuous veil or curtain of purified air. Furthermore, the following publications can also be mentioned, each of which describes specific features of known devices and methods for emitting fragrances in certain usage situations: DE 601 23 245 T2, in particular relating to a portable storage container with cassette-like fragrance receptacle, and DE 60 2005 001 213 T2, in particular relating to a so-called fragrance release system with a plurality of microvalves arranged in a valve block with direct connections.

[0004] Based on the state of the art, there is a need for devices and methods for the optimized, individual-specific provision of olfactory impressions in the shortest possible or as precisely predefined time windows as possible. SUMMARY OF THE INVENTION

[0005] The objective is to provide devices and methods that enable the olfactory perception level to be activated as precisely and precisely as possible, preferably in synchronization with other perception levels, especially those addressed by audiovisual content. It is also necessary to design devices and methods for emitting a multitude of odors / scents specifically for a given individual in such a way that a comparatively large number of odors / scents can be stored and activated or emitted in a situation-specific manner, either manually and / or at least partially automatically.

[0006] This object is achieved by a device according to claim 1 and by a method according to the corresponding independent method claim. Advantageous developments of the invention are explained in further independent claims and the respective subclaims. The features of the exemplary embodiments described below can be combined with one another unless explicitly stated otherwise.

[0007] Provided is an olfactory emission device configured to emit a plurality of odors / fragrances in the region of or directed toward at least one nostril of an individual, comprising at least one fan unit and at least one motor, wherein a plurality of odor pads are provided / held in a magazine and are individually activatable;

[0008] According to the invention, it is proposed that the olfactory emission device is designed for mobile use by an individual (in particular designed for arrangement on the head or at least in the neck / upper body region of the individual) and is designed to activate a / the respective odor pad by manual and / or motorized positioning of the corresponding odor pad individually fed by means of the magazine at a designated activation point and is designed to generate forced convection by means of the fan unit via the activation point and is designed to supply the corresponding odor / fragrance via at least one supply to at least one nostril of the individual. This enables a very targeted provision of the respectively desired fragrance in a comparatively narrowly pre-definable time window, optionally coordinated by control / regulation technology, e.g. with the breathing rate of the individual.In other words: The activation of the desired fragrance occurs by actuating the magazine or its kinematics, whereby the respective odor pad is positioned in the flow path of the forced convection or at least emitted there, and in a second step, further control / regulation of the type and manner of forced convection can optionally take place.

[0009] It should be understood that the emission device described here is designed in such a way that simply activating the corresponding odor pad can trigger the desired emission within the desired time window. In other words: Control / regulation of the type of forced convection is not necessarily required. The emission of the corresponding fragrance can be stopped again simply by actuating the magazine again, either by first positioning an empty position (no further odor pad) at the activation point or by directly positioning a new / further odor pad at the activation point. This can be specified by the person skilled in the art through the design of the magazine and / or the method of actuation. The user can also influence this, e.g. by actuating the magazine kinematics either once or twice.

[0010] Activation is understood in particular as the mechanical breaking open of a pad, whereby activation can alternatively also refer to, for example, an energetically / thermally based release, e.g., when using an emission unit that acts on the respective pad or odor reservoir in the area of ​​the activation point. If, according to the present disclosure, activation by positioning is referred to, this is synonymous with release after positioning at the activation point. In this respect, the activation process can also include at least one optional measure for, in particular, accelerated or targeted release, e.g., through thermal action.

[0011] Personified terms, unless formulated in the neuter here, can refer to all genders within the scope of this disclosure.

[0012] According to one embodiment, the respective odor pad can be positioned along a movement path predetermined through the magazine up to at least the activation point, in particular along a circular path around a forced convection flow path or in a band-like manner, starting from a cassette pivot point to or around at least one other cassette pivot point. This also makes it possible to temporally predetermine the activation of the respective fragrance through a kinematic actuation, in particular largely independent of the intensity of a current forced convection.

[0013] According to one embodiment, the magazine comprises a revolving drum and / or a cassette, with the odor pads arranged on a circular diameter within the revolving drum or arranged one behind the other, e.g., within a band in the cassette. This also facilitates a specific, situation-dependent selection / activation of individual scents, either via a circumferential position-specific rotation of the drum or via a rotation-position-specific positioning of the band.

[0014] According to one embodiment, the activation point is formed by a radius of curvature that is significantly smaller, in particular at least a factor of 2 smaller, than the smallest radius of curvature on a / the movement path of the odor pad through the olfactory emission device, apart from the activation point. This also enables activation of the respective fragrance based on the geometric characteristics of the movement path contour at the activation point, resulting in a particularly robust design (activation already by the circular displacement of the band).

[0015] According to one embodiment, the respective odor pad is embedded in a foam-like, porous, open-pore, or sponge-like cushion (e.g., made of nonwoven material, emission fleece, distribution fleece) and, upon passing the activation point and / or upon mechanical action at the activation point, saturates the cushion or wets it with fluid. This also facilitates a certain temporal retention of the scent – ​​if the scent should nevertheless dissipate more quickly, the pad can be relocated (i.e., moved away from the activation point or out of the airflow path).

[0016] According to one embodiment, the respective odor pad is embedded in a band, preferably a three-layer band (in particular, individually guided for each layer, at least with individual guidance of the inner layer), which is guided over the activation point, which protrudes, in particular, like a pin or finger, into an inflow channel of the supply. This also facilitates the specification of a specific sequence or chronology for the emission of different scents and also facilitates the provision of a very large number of different scents.

[0017] According to one embodiment, the olfactory emission device comprises a control / regulation unit and a wireless communication module, wherein the olfactory emission device is configured to position or activate the respective odor pad in response to a signal, e.g., a time-related or individually triggered signal, optionally chronologically according to a sequential arrangement of the odor pads, e.g., in a band, or individually, particularly when the odor pads are arranged in a revolver drum. This also facilitates implementation in coordination with other audiovisual media.

[0018] According to one embodiment, the odor pads are contained in a revolving drum and are manually positionable, with the revolving drum being rotatable from one discrete rotational position to the next using a rotary wheel or push button. This can further simplify personal use, not least for those who are more technologically reluctant, possibly without the need for any supporting computer programs.

[0019] According to one embodiment, the olfactory emission device is configured for manually and / or controlled / regulated triggered individual activation of at least five or at least ten odor pads, preferably at least fifteen odor pads, either chronologically sequentially or individually selectively selected. This also facilitates implementation in coordination with other audiovisual media, such as a movie.

[0020] The above-mentioned object is also achieved by an olfactory emission device according to the corresponding independent device claim, namely by an olfactory emission device configured to emit a plurality of odors / fragrances in the region of or directed at at least one nostril of an individual, comprising at least one fan unit and at least one emission unit, wherein a plurality of individually activatable odor reservoirs are provided / maintained;wherein the olfactory emission device is configured to expel odor fluid at a reservoir outlet of / the respective odor reservoir by means of the emission unit, in particular based on piezoelectrically and / or thermally generated emission, and is configured to generate forced convection via the respective reservoir outlet or an activation point coupled thereto, and is configured to deliver the corresponding odor / fragrance via at least one supply to at least one nostril of the individual. This results in the aforementioned advantages, in particular with regard to a particularly high degree of miniaturization and the use of already established printing technology for the purpose of expelling olfactory-perceivable (odor) fluid from the respective reservoir or odor pad or band.

[0021] The olfactory emission device comprises at least one bracket in which the at least one fan unit and the at least one emission unit are / can be integrated, or which is dimensioned and configured such that a receiving cavity is provided for the at least one fan unit and the at least one emission unit. Such miniaturization also improves mobility and usability.

[0022] It should be understood that an emission unit can also be provided independently of the device's other features, thus being compatible with the activation concept through manual and / or motorized positioning using a magazine. In other words, a pressure emission principle can optionally be implemented for the release of the scent at the activation point.

[0023] According to one embodiment, the plurality of individually activatable odor reservoirs is / are provided / held in a type of band in a cassette and can be positioned on a movement path along / in front of the emission unit.

[0024] Optionally, the plurality of individually activated odor reservoirs can be provided / stored in a cartridge aligned with, extending into, or open toward the feeder. This also facilitates release based on a printer principle.

[0025] According to the invention, the olfactory emission device can be integrated into a personal item from the following group: headset, glasses, or protective helmet. In other words, the inventive design facilitates miniaturization and personalization as a personally usable device.

[0026] The olfactory emission device comprises at least one bracket in which the at least one fan unit, the at least one motor, and the magazine are integrated / can be integrated, or which is dimensioned and configured such that a receiving cavity is provided for the at least one fan unit, the at least one motor, and the magazine. In other words, the inventive concept also consists in miniaturizing the components essential for olfactory emission (or the mechanisms required therefor) such that they can be incorporated into a bracket, e.g., of glasses or similar personal items worn in front of the face or on the head.

[0027] Optionally, the olfactory emission device can also be designed to be integrated into one of the following personal items: selfie stick, headphones, cap, hat, outerwear, jewelry, handheld game console, nose ring. Based on the miniaturization described here, the skilled person can adapt the olfactory emission device such that it can also be integrated into such personal items.

[0028] It should be understood that the embodiments of the olfactory emission device described here can each also be equipped with a connection for supplying gas or fluid from outside. Such a connection comprises, for example, an at least semi-pressure-tight connection coupling and / or an adapter piece with a line section, for example, configured for connecting the olfactory emission device to a line section of a central odor fluid generation and supply system installed, for example, in a cinema. Such a central odor fluid generation and supply system comprises, in particular: a central pressure management system, a central transport fluid supply system (e.g., air as the transport medium), a supply system to individual seats or target positions of the individuals, a central control / regulation system, and a central odor (pad) reservoir.In principle, the central overall system is designed in a manner comparable to the system components that can be used individually, but is not miniaturized but scaled in size depending on the number of individuals to be served, e.g. depending on the size of a cinema hall.

[0029] According to one embodiment, the olfactory emission device has a connection for supplying gas or fluid from an external source, particularly from a central odor fluid generation and supply system. This also facilitates comparatively simple coupling with a central odor emission control system, e.g., in a movie theater, without having to forego the corresponding personal item (especially glasses).

[0030] The aforementioned object is therefore also achieved by a central odor fluid generation and odor fluid provision system configured for coupling with a plurality of olfactory emission devices described here, comprising a plurality of connections for supplying gas, fluid from the outside of the central odor fluid generation and odor fluid provision system to the respective olfactory emission device, wherein the respective olfactory emission device also has a connection configured for coupling with the corresponding connection of the central odor fluid generation and odor fluid provision system. The central odor fluid generation and odor fluid provision system is installed, for example, in a cinema and can also comprise, for example: a central pressure management system, a central transport fluid supply system (e.g.Air as a transport medium), supply system to individual seats or target positions of the individuals (headrest, armrest, backrest), central control / regulation system, central odor (pad) reservoir. It should be understood that such a central odor fluid generation and odor fluid supply system is also advantageously configured for coupling with personal items that do not necessarily have to be equipped with the components responsible for olfactory emission, for example, with comparatively simple goggles, which can also be provided as disposable items.

[0031] The above-mentioned object is also achieved by a method according to the corresponding independent method claim, namely by a method for emitting a plurality of odors / fragrances individually for each individual in the area of ​​or directed towards at least one nostril of the individual, wherein a manual and / or motorized positioning of a plurality of odor pads provided / held in a magazine carried by an individual, in particular a revolver drum or a cassette, takes place, wherein forced convection is generated by means of at least one fan unit, wherein a / the respective odor pad is individually activated by positioning the corresponding one individually by means of the magazine, in particular by means of the revolver drum or in a row one behind the other, e.g.within a band by means of the cassette, supplied odor pads at an activation point provided for this purpose, in particular based on at least one trigger that can be predetermined by control / regulation technology, wherein the forced convection is guided / conducted via the activation point, wherein the corresponding odor / fragrance is guided via at least one feed to at least one nostril of the individual, wherein the at least one fan unit and the magazine are arranged in a bracket of an olfactory emission device worn / carried by the individual and effectively generate the at least one fragrance there. The method is carried out with / by use of an emission device previously described above. This results in the aforementioned advantages, in particular with regard to targeted, individual-specific activation of the olfactory perception level, in particular in narrowly predefined time windows.

[0032] According to one embodiment, the magazine has a kinematic system that positions the respective odor pad according to a predefined movement path and activates it in the area of ​​a / the flow path of forced convection, optionally by motor and / or at least partially manually. This provides, not least of all, a very simple and robust method of activation and, if necessary, direct release, in particular based solely on kinematic actuation, for example, even purely manually.

[0033] According to one embodiment, the respective odor pad is guided into the activation point over a convex contour or through a constriction and activated by displacement / deformation. According to one embodiment, the respective odor pad is activated upon passing the activation point and / or upon mechanical action at the activation point. According to one embodiment, the respective odor pad is / is embedded in a band, which is guided over the activation point, which protrudes, in particular, in a pin-like / finger-like manner, into an inflow channel of the supply, and upon activation, emits into a stream of forced convection. Based on the present disclosure, the person skilled in the art can implement a particularly adequate manner of activation and release depending on the design of the pads.

[0034] According to one embodiment, the respective odor pad is positioned and activated in response to a signal, e.g., a time-based or individually triggered signal, either chronologically according to a sequential arrangement of the odor pads, e.g., in a band, or individually selectively, particularly when the odor pads are arranged in a / the revolver drum. This also facilitates precisely timed activation / release, especially with minimal or optionally no user interaction (i.e., optionally fully automated / motorized).

[0035] According to one embodiment, the odor pads are positioned depending on the activation or power level of a rotor of the fan unit. This can specify the perceptibility of the respective scent even more precisely, while minimizing air volume and contamination.

[0036] According to one embodiment, the forced convection is guided over the activation point in at least one predefinable time window, in particular in a time window that is predefined depending on the time of activation of the corresponding odor pad. This also promotes minimal odor contamination of the environment.

[0037] The aforementioned object is also achieved by a computer program product comprising instructions which, when executed on a computer, cause the computer to execute an algorithm for controlling / regulating a method according to the present disclosure on the computer or by means of the computer, in particular a computer program product configured to generate instructions or signals for, for example, the time-related or synchronized positioning or activation of individual odor pads, in particular in coordination with a running medium such as a film sequence. Based on the aforementioned advantages, this also enables a very high degree of automation or computer-implemented use, for example in the context of an odor cinema program.

[0038] The aforementioned object is also achieved by using a magazine designed as a revolver drum or cassette for specifying a kinematics for a movement path for positioning a respective individual one of a plurality of odor pads for activating the corresponding odor pad at an activation point provided for this purpose in the region of a flow path of a forced convection generated by means of at least one fan unit for emitting at least one odor / fragrance of a plurality of odors / fragrances in an olfactory emission device worn by an individual via at least one feed into the region of or directed towards at least one nostril of the individual, in particular of a magazine that can be actuated by control / regulation technology;In particular, in an olfactory emission device according to the present disclosure, in particular installed in a pair of glasses with a hinged frame tube or a frame with a sealing lip, optionally with an extendable tube extension. This allows the aforementioned advantages to be realized, in particular with regard to both manual and motorized or fully computer-implemented activation / release.

[0039] The aforementioned object is also achieved by using an olfactory emission device according to the present disclosure for providing at least one fragrance from a plurality of potentially selectable fragrances in at least one of the following situations: timed to at least one trigger generated as a function of the progression of an (audio)visual medium (e.g., a cinema film), in response to a manual actuation, in particular of a / the magazine of the olfactory emission device, as a function of at least one location parameter (in particular specific location coordinates) and / or at least one time parameter (in particular time of day parameter); in particular by applying a method according to the present disclosure, in particular with the emission device installed in spectacles with a hinged frame tube or frame with a sealing lip, optionally with an extendable tube extension.This allows the aforementioned advantages to be realized, particularly with regard to the most precisely regulated adjustment possible, e.g., depending on other audiovisual media, especially in the context of a similar / simultaneous group experience involving numerous individuals (a scent party or similar). Optionally, an emission unit for releasing the respective scent can also be implemented.

[0040] The invention is explained in more detail below with reference to individual specific applications: The invention relates to a portable device for aromatizing and preferably also for purifying the inhaled air in the immediate vicinity of the nose. Odor emitters are known which can be used by people to apply a liquid to clothing or skin or which can be nebulized into the room air, for example so-called room sprays with fans. Such a room spray has a large structure and the odor emissions fill the entire room. Furthermore, so-called portable air filters are known, which can be integrated into headphones, for example, and can transport filtered air into the mouth and nasal cavity via ducts.

[0041] The difficulty so far has been that it's not reasonable to expect an individual or user to accept, for example, less pleasant-smelling scents. However, particularly in the areas of film, television, or virtual media, unpleasant odors may also be emitted, e.g., to intensify scenes without causing the clothing or room to have a lasting unpleasant smell. Due to the current size, only a relatively small number of different scents are possible.

[0042] Accordingly, one of the challenges of the present invention is to further develop a personally wearable device such that a volume of air containing volatile fragrance molecules is transported to the nose area or toward the nasal cavity. From there, the airflow caused by breathing reaches the olfactory organ, where it converts the chemical signal into a corresponding electrical or neural signal, and activates the desired olfactory sensory perception in the brain based on a predetermined aroma. In this way, odors can be emitted that match images and thoughts to enhance and intensify the sensory impression.Such a device must also be small in size, inexpensive, wearable on the body or clothing, and should, if possible, also be able to emit a specific odor from a reservoir or the like from many different previously determined odors at specific times or in specific comparatively small time windows, which are located, for example, in a small container, a capsule or chamber, in order to be able to inhale the corresponding aromatized air volume immediately afterwards, in particular with the next breath, for example through the nose.

[0043] A key idea of ​​the present invention is based on the concept of designing the device as a portable and small device in a housing, and having many different fragrance aromas emitted via an air duct with a nozzle near the nostrils, depending on time and / or location. The aim is to release as few fragrance molecules as possible so as not to overstimulate the olfactory organ. Advantageously, not the entire room or the entire spatial volume around the individual is contaminated with odor molecules. A large number of scents can be emitted one after the other, or, for example, two scents can be emitted in combination with one another. The device can be equipped with various electronic components, such as a smartphone, to further increase its range of uses and functions.

[0044] The production of the aromatized air can advantageously take place in a housing which accommodates at least one (air) supply, in particular comprising at least one air duct, a fan, filter media, a power supply, a computing unit, sensors, optionally also extendable microphones, cameras and screens, as well as an outlet nozzle and the magazine of the odorous substances, and the aromatized air can be discharged through at least one outlet nozzle positioned / positionable near the nostrils.

[0045] Such a housing can also be integrated into, for example, glasses, e.g., VR glasses, a necklace, a brooch, a cap or hat, a handheld console of a gaming device, headphones, a protective helmet, or a nose ring, or at least partially attached to such a component or object. Alternatively, the entire device can also be designed as a stand-alone device with a comparatively compact design.

[0046] In an embodiment as glasses (or integrated into glasses), the device can be integrated into or at least attached to the temples, for example. In the integrated variant, the frame, which also holds the lens, can serve as an air duct and also have an air outlet (with or without a nozzle) that directs the air flow towards the nostrils. In the embodiment for attachment to the temples, the device advantageously has an air outlet for attaching a tube that is at least partially rigid, flexible and / or bendable and can consist of one or more tube sections. Advantageously, the outlet of the tube has an adjustable nozzle. Furthermore, this tube can also have at least one joint, by means of which an angular adjustment of the orientation of the tube or individual tube sections is facilitated and positioning to the nostrils can be even more targeted.

[0047] To use the device, the user can wear glasses or another similarly functioning object, particularly on the head, or wear the object as a type of accessory on the body, particularly in the neck, shoulder, or upper body area. Alternatively, it can be placed in the immediate vicinity of the user.

[0048] The device is preferably equipped with a plurality of odor containers or with odor-impregnated materials (here also generally referred to as pads), which are advantageously encapsulated in airtight chambers or compartments, and can be controlled wirelessly and / or wired in combination with a control / regulation unit, in particular such that a suitable or predefined / predefinable odor / fragrance can be emitted in / at specific situations, times, locations or needs of the user or, for example, depending on image scenes or similar audiovisual impressions. These chambers are designed, for example, like a bracelet or ring and are fixed to one another or integrally connected to one another, and are located, for example, in an annular housing which, for example, is rotatably mounted around another housing of a fan.The housing of the chambers advantageously has a through-opening, whereby the air flow generated inside can flow through the corresponding chamber, absorb the volatile scents there and then reach the nasal area via at least one channel (here also generally referred to as supply).

[0049] Advantageously, the air to be emitted is first passed through filter media such as activated carbon filters, HEPA filters and / or catalysts and is freed from other odors and particles, whereby the air ducts can also be provided with a catalytic coating.

[0050] According to one embodiment, a unit for inducing forced convection via a movement path through the device is formed by at least one air flow generator, which is arranged in series with the fragrance emitters (pads), the inner and outer air ducts, and the air filter systems in or on the corresponding enclosure or housing. The order of these components can be coordinated and adapted based on the present disclosure, and part of the air duct(s) (generally referred to here as a supply) can also be located outside the housing. Odor molecules are bound in a liquid and / or solid material, which is enclosed in a flexibly deformable or rigid compartment or pad, e.g., advantageously in an annular or disc-shaped drum magazine, in a tape roll, and / or on a circuit board.

[0051] The air flow generators can be designed in a radial, diagonal, and / or axial configuration. Furthermore, a compressor, a bellows pump, or an electric motor-driven air pump can also be used to generate the air flow.

[0052] An electrically or electromechanically driven fan of the device advantageously consists of a synchronous or asynchronous electric motor, a fan wheel (rotor) with the associated shaft and connections. The fan wheel is usually designed as a single unit, which can also be divided into two elements: The first element is designed as the rotating housing of the electric motor, and the second element is designed as the fan propeller. These two elements do not necessarily have to be used as a materially connected component. For example, the fan propeller has an inner ring that can be connected to the housing of the electric motor in a force-fitting and / or form-fitting manner. This allows for the attachment and replacement of fan propellers of different designs on an electric motor (particularly according to radial, axial, or diagonal designs).

[0053] Furthermore, two electric motors can be arranged one above the other or nested inside the other, particularly to generate two rotational motions within this installation space. These two motors are operated independently of each other. In the nested version, one electric motor is located in the center of the second electric motor. This allows one electric motor to operate the magazine.

[0054] The air filters can be designed as particle separators for gases and solids. Furthermore, coated surfaces can also be provided, which, for example, enable the conversion of gas molecules. Activated carbon, nonwoven, paper filters, or even catalysts are particularly useful for such separation or conversion mechanisms and can be implemented within the scope of the present invention.

[0055] The propeller gains an additional function when activated carbon filters such as fleece, foam, etc. are securely attached and fixed between the individual propeller blades.

[0056] As a further embodiment of the filter system, the filter can also be designed as a cassette, which is arranged in the air duct and is easy to remove and change / replace.

[0057] The olfactory emission can be advantageously carried out individually for each fragrance or each pad by activation (e.g. breaking open a pad, or pulsed release) and / or positioning in the air stream or on the predefined movement path.

[0058] When positioned using an electric motor, for example, a ring can be rotated around its axis of rotation. This ring can consist of individual chamber segments, each of which undergoes the actual aromatization. The chambers are advantageously separated from one another by partitions whose alignment lines emanate from a center and are arranged vertically between two annular discs. The beginning of the partitions begins at the inner diameter and ends at the outer diameter. A bore between the partitions, perpendicular to an annular disc, can provide an additional chamber to accommodate the fragrance container or fragrance-impregnated material.

[0059] The air channel can be modified using an intermediate piece of the ring, in particular to direct the respective smell / fragrance to the olfactory organ (nose) through the generated airflow. This type of application is advantageous, for example, for a drum or disc magazine and for a tape roll. Absorbent materials are soaked with the olfactory liquid, or the liquid is encapsulated (pads). These capsules or pads can be burst, for example, using a hammer-anvil principle, and the liquid (odor fluid) can be absorbed by a surrounding absorbent material. It can then be released from this carrier material again through evaporation or convection and carried away by the airflow. The hammer-anvil principle is implemented, for example, using rollers or an electromechanical motor.

[0060] In the activation variant (e.g., activation by a measure on the pad), an emitter is activated in the air duct, which diffuses the aromatic liquid from a container through a nozzle or opening, e.g., based on thermal application or heating, vibration, pumping, suction, illumination, and / or rubbing. This emitter is advantageously located on the container or connected to it.

[0061] Optionally, a component of the emission separator that causes the emission is located in the flow channel or is activated within it. The separation of the fragrance emissions occurs, for example, through heating, vibration, injection, or evaporation, and is advantageously directed along the desired path through the device by flowing in, around, through, or suction into the air channel.

[0062] The air ducts can be integrated within the device or attached as attachments, screwed on, clipped on, glued on, and / or otherwise. These connections can be force-fitting and / or form-fitting, or even materially bonded, particularly in combination with the flow duct housing.

[0063] It should be understood that, in particular, the following two types of air aromatization can be used: direct aromatization and indirect aromatization. For direct aromatization, the following principles can be implemented in connection with the present invention: injection and atomization, the latter of which can be subdivided into piezo injection, heating bladder injection, and pump-nozzle injection. For indirect aromatization, the following principles can be implemented in connection with the present invention: pressure injection, pressure application in combination with physical introduction into the air duct. The pressure injection can be carried out directly into the air duct, and / or through a heating chamber and then into the air duct, and / or onto a carrier material located in the air duct, and / or onto a carrier material that is then fed into the air duct.Alternatively or additionally, the activation of the fragrance emission can be based on one of the following pressure application principles: ballpoint pen refill, fountain pen, spraying, atomization.

[0064] The olfactory emission device described here is advantageously small and lightweight, making it portable, integrable, attachable, or installable. It fulfills the task of constantly or rhythmically conveying air with the lowest possible concentration of volatile odor molecules into the air inhalation area of ​​the nose within a specific, predefined time period (manually and / or actuator-controlled / regulated), without contaminating the environment with these odor molecules. The device is advantageously integrated or attached into clothing, wearable, or utility items. The clothing items include, for example, hats, caps, tops, or other items. The wearable items include, for example, glasses (commercially available glasses, VR or 3D glasses), pendants, watches, brooches, or other items. The utility items include, for example, fans, handheld consoles for gaming devices, or other items.

[0065] The air is drawn into a housing by a fan, pump, compressor, or other device and then circulated through ducts (forced convection along a predefined path through the device to the individual's nose). The air can be cleaned before, in, or after the fan. The air is then distributed through ducts. The air is aromatized by the emission of aerosols, which originate either from a container or from a carrier material containing the liquid. The aromatized air is then precisely diffused to the nasal area through a nozzle, with the lowest possible concentration and within the narrowest possible predefined time window.

[0066] The emission of fragrance aerosols from the carrier material is advantageously achieved by a change in the state of aggregation. The liquid containing the odor molecules is either applied to the carrier material directly before emission by injection, dripping, pumping, and / or suction, or it is already embedded in the carrier. The carrier material is positioned in an air duct section of the desired convection or flow path immediately before the desired emission time. The odor fluid can also be converted into a volatile gas state by injection, dripping, pumping, or suction into a diffuser, in a heating chamber, or a combination of both measures, so that it can be carried along by the air flow.

[0067] The device preferably consists of a housing, at least one filter, a fan with a housing, at least one fragrance magazine with a housing, channels, at least one voltage source, a processing unit or a control / regulation unit, a communication unit, sensors, motion conversion elements, and actuators. The device is advantageously attached to the desired object by means of positive and non-positive connections.

[0068] The present invention, which is described in more detail below, is an olfactory emission concept in which an aerosol of volatile odor molecules is introduced into a self-generated air flow (advantageously also purified, for example, with regard to particles) and this air flow is then introduced into the area of ​​the nose (forced convection).

[0069] Scents consist of tiny particles, odor molecules. Hundreds of different odor molecules combine to create a scent. In order to perceive a scent, dissolved odor molecules must reach the olfactory epithelium from a liquid. The odorants are dispersible in the air, volatile, and must be above the individual's odor threshold to be perceived. For example, the individual's exposure time is relevant for odor memory and / or the concentration of the scent is relevant for sensory processing.

[0070] The transition of the odor molecules from the bound state in a liquid to the volatile state of the gas phase occurs, for example, through biochemical and physical processes.

[0071] The device described here thus holds at least one fragrance that can be expelled from a liquid and transported to the destination in an air flow, wherein the air can be pre-cleaned and can be pumped or sucked by means of at least one fan on a pre-definable flow path, e.g. distributed through channels and tubes from a nozzle to the inhalation area of ​​the nose.

[0072] The device comprises a housing which contains an air filter, an air flow generator, a plurality of air ducts, a magazine of a plurality of odor units (in particular pads), a device for releasing the odors, a plurality of electronic components and an outlet opening to which a nozzle or an extension tube with a nozzle can be attached.

[0073] For example, the rotation of a fan draws air into the device, optionally passing through at least one filter, passes through the fan to the aromatization chamber section (magazine and activation point), and is then transported through an air duct to the outlet opening. At the outlet opening, an adjustable nozzle directs the air precisely into the nasal area. Extending the nozzle with a tube allows for the aromatized air to be precisely directed toward at least one nasal inlet. The device can be worn by the user or placed near them. The device can be integrated into a worn object as a single unit, or attached to a worn object as a retrofittable accessory.

[0074] Advantageously, the optionally provided at least one air filter comprises a particulate matter and / or a gas phase filter.

[0075] The air flow is generated, for example, by means of a fan, compressor, bellows or air pump (at least one electromechanical component or actuation / drive thereby).

[0076] The magazine for the various odorous substances consists, for example, of a ring drum, disc drum, tape roll, cassette, printer cartridge with nozzle head or containers as a linear drum with nozzle heads.

[0077] For example, ring and disc drums are designed as sections of the air duct or the predefined air flow path. For example, a section of the belt roll rotates into an opening in the air duct or runs transversely through the air duct.

[0078] For example, a cartridge unit or the linear drum is attached to the air duct outside the air duct, with nozzles provided in the wall of the air duct protruding through openings into the air duct.

[0079] The release of odorous substances from the liquid into the airflow occurs, for example, through evaporation and erosion processes. The fragrances can be released from a liquid carrier material (odor fluid), for example, through evaporation.

[0080] For example, the odor fluid is injected into the airflow to spread and be carried away before evaporating in the nasal area.

[0081] For example, the odor fluid is injected into a pre-chamber, where it evaporates with or without further energy input, or changes into the gas phase, or spreads as an aerosol.

[0082] For example, the odor fluid is sprayed onto a carrier material, which is then transported into the air duct, where the corresponding scent can pass into the gas phase and be carried further.

[0083] The respective liquid containing the fragrance molecules (odor fluid) is contained, for example, in a capsule, in a container, on a band, or in a carrier material. The fragrances are of natural and / or synthetic origin.

[0084] The electronic components of the device include, for example, actuators, sensors, a processing unit, memory, microphone, cables, communication means and power supply.

[0085] For example, electric motors position the individual odorants or pads in the air duct, build up pressure in the corresponding container or cartridge and / or move elements of the device, e.g. for the purpose of mechanically breaking open an odor pad.

[0086] Sensors can be used to detect the actual state, particularly to determine parameters and facilitate control. Electrical components can bring the device to the desired state in terms of device technology and / or functionality.

[0087] A communication unit serves for the interaction of the device with at least one other system, e.g. with an audiovisual system, by means of which the olfactory emission is to be coordinated at least in terms of time.

[0088] A voltage source, which can optionally be used as an energy storage device for mobile use, provides the energy needed to carry out the electronic processes described here.

[0089] A computing unit with memory processes the respective information and controls / regulates actuators and similar processes and measures.

[0090] The device is designed to produce a desired olfactory emission by means of electronic means at variable time intervals and time exposures (time windows).

[0091] In the following, individual aspects of the present invention are considered individually.

[0092] Position and placement of the device: For example, the device can be integrated or attached to the following wearing objects: glasses, VR glasses, cap or hat, headphones, necklace, brooch, headphones with or without microphone, jacket, neck brace, nose ring and table device.

[0093] In the case of glasses, for example, the device is integrated into the temple or attached as a separate device to the temple and frame, whereby the outlet tube with nozzle can be integrated into the frame.

[0094] In the case of VR glasses, the device with outlet pipe and nozzle is integrated into the housing or holder, or it is attached to any location on the VR glasses.

[0095] In the case of a hat, such as a sports cap, the device can be attached to the sun visor or integrated into it.

[0096] The device can also be attached to a pendant or necklace.

[0097] The device can be attached to a brooch or, in the form of a brooch, to an outer garment.

[0098] The device can be integrated into the ear cup, either with a headband or individually as an earpiece. A microphone tube, for example, can be used as an extension channel for the airflow. The microphone can also be used, when integrated into the device via a control system, to record the individual's breathing rate and generate a pulsed airflow in accordance with this rhythm, particularly to minimize the emitted volume (minimizing olfactory contamination of the environment). The integration of a microphone is feasible in all variants of the device described here.

[0099] A connection between the device and an extension channel can be realized, for example, by means of a thread, magnet or similar plug.

[0100] An extension tube can also be incorporated into the housing of the device as an extendable unit.

[0101] Carrier liquid: The carrier liquid can be of natural or synthetic origin, depending on the type of fragrance molecules or the desired method of emission. The vapor pressure of the liquid is a crucial parameter, as is the viscosity if necessary. The liquid contains the added odorant and does not emit any odor of its own.

[0102] Liquid carrier material: The preferred carrier material is an open-pore structure made of synthetic and / or natural fibers, which are largely bonded together. The liquid is absorbed into the pores between and within the fibers through physical and chemical properties or interactions between the fibers and the liquid itself. The carrier material itself is odorless and free of harmful substances and has a stable structure. Functionally, the carrier material acts as a buffer or intermediate station for the liquid containing the volatile odorous substances. Evaporation or release occurs on the surface of the fibers.

[0103] Fan with integrated filter: The fan advantageously has a two-part design. The propeller or rotor is advantageously arranged on an inner ring, which can be attached to the edge of the housing of an electric motor or drive. Attachment is preferably achieved using positive and non-positive connections. The following connections are possible: wedge connection, pin-and-groove connection, hook-and-loop connection, adhesive connection, screw connection, and press connection. A specialist can select the most suitable connection for the respective application.

[0104] For example, in a wedge connection, the inner ring of the propeller wheel can be additionally equipped with a rubber ring to clamp the wheel onto the housing like a plug without any play. The housing of the electric motor is slightly conical at the bottom.

[0105] For example, in a pin-and-groove connection, at least two pins are arranged on the housing of the electric motor, with the pin having a flat head or edge. The corresponding groove is provided on the inner ring of the propeller blades to ensure the connection is functional.

[0106] For example, in a screw connection, there is an internal thread in the inner ring and an external thread on the edge of the housing.

[0107] For example, with a hook-and-loop fastener, the inner ring is flexible and therefore not completely bonded in one place. This allows the inner ring to be wrapped around the housing and connected.

[0108] For example, with an adhesive bond, a double-sided tape is glued into the inner ring and then bonded to the housing. The adhesion to the housing is less strong than the adhesion to the propeller wheel, allowing for easy removal.

[0109] For example, in a press fit, the inner ring of the propeller is made of a stretchable material. This compression is achieved through an interference fit.

[0110] Based on one of these exemplary connections, the fan wheel can be assembled and disassembled. This allows the outlet flow to be modified so that it can discharge the air radially, diagonally, or axially. This makes the device described here relatively easy to adapt to the respective application, for example, for the goggle variant. Thus, part of the air flow can be used for aromatization and the other part for ventilating the eyes or the skin area behind the goggles. Depending on the magazine type, the aromatized air is passed on, for example, directly radially (drum magazine) or axially (disk magazine).

[0111] The propeller wheel is advantageously removable and replaceable. This allows the space between the individual propeller blades to be equipped with a filter medium, e.g., by means of a material, force, and / or form-fitting fixation. A HEPA and / or activated carbon filter, for example, can be used. Optionally, additional filter materials can be attached to the propeller blades by screwing, clipping, slipping over, gluing, sliding on, or attaching them in a similar way (functionally extending the fan function while keeping the device's housing as compact as possible).

[0112] For example, for screwing on, the propeller has at least one hole with a thread, to which the filter, which has a hole, can be fixed with a screw.

[0113] For example, for plugging in, the propeller has at least one hole onto which the filter, which has a pin with or without a head, can be plugged.

[0114] For example, for the over-the-top installation, the filter, which has a bag or at least a rubber band, is placed over the propeller.

[0115] For example, the filter has a double-sided adhesive tape that is stuck to the propeller.

[0116] For example, the propeller has a groove or rail for sliding on, via which the filter can be connected to the plug-in head.

[0117] For example, the propeller has loops and the filter has hooks (Velcro fasteners) for attaching it, or vice versa.

[0118] Filters: The optional filter media can also be positioned in other locations, for example, in front of, next to, or at the inlet, or after, next to, or at the outlet of the fan. Filtration (air treatment) occurs before the air is aromatized. The filters can also be designed as small cassettes that are inserted into the air duct (replaceable). The respective component can optionally be coated with a catalyst layer to convert pollutants on its surface. The main function of the respective filter / filter medium is to remove odors from the intake air, for example, when visiting a movie theater.

[0119] The air to be scented is therefore advantageously freed of odors upstream of the release of the fragrances in such a way that no noticeable scent mixing occurs. The use of a particulate filter can also be provided, particularly upstream of an activated carbon filter, particularly to prevent the activated carbon filter from becoming clogged.

[0120] Fan housing: This housing advantageously has at least two outlet openings. The air drawn in axially, diagonally, and / or radially can also be discharged axially, diagonally, and / or radially. The inflow direction is advantageously different from the outflow direction.

[0121] The fan housing is advantageously integrated into the device housing or mounted on it and is shaped like a flat cylinder or ring that is open at the top. In some applications, such as glasses (including 3D glasses), the bottom of the housing and the side wall of the device have an opening that is aligned to allow the user of this device to ventilate the skin and / or eyes inside the glasses or to generate a suitable breeze.

[0122] The outlets vary in direction depending on the design: axial, radial, and / or diagonal. The airflow can be divided to reach the nasal area and / or a specific area of ​​the skin. An optional opening for eye ventilation can be closed with a flap. This closure is preferably achieved with a sliding flap or a hinged flap. A rotating flap can also be used.

[0123] Advantageously, the air intended for the eye area is only filtered and does not enter the aromatization area or is not directed over the activation point; in this respect, the device can also define at least two flow paths.

[0124] Fan motor: The fan motor can have multiple electric motors. The electric motors can be arranged on top of each other or nested. One motor can rotate the fan and another motor can rotate or translate the correspondingly movable component of the magazine. The motors can also perform other tasks, such as extending the outlet nozzle, which can also be housed in the housing. In a variant in which the fans are nested, one motor is located within the center of the other motor. In both variants, the motors can be controlled separately. In the outer motor, the rotor ring is advantageously located on the outside as a permanent magnet. This rotor is advantageously arranged like a ring around the coils. In the inner motor, the rotor is advantageously located inside as a shaft.The rotation axis and the center line of the rotor are advantageously exactly the same.

[0125] Air ducts (also generally referred to here as supply): The air ducts in the device's housing serve to redirect or define at least one flow path. The air ducts can also be designed to be interchangeable and replaceable. The air ducts can also split the volume flow, in particular to direct aromatized air to the nose on the one hand and non-aromatized air, for example, to the eye area or skin areas, particularly behind a visor or glasses, on the other. The air ducts can be attached to the housing as elements, for example, or integrated into the respective wearing object.

[0126] Extension tube: The extension tube with nozzle attachment can also be integrated into the device housing. The nozzle outlet can be directed toward the nose. When the tube with nozzle is extended, this unit can bend or align toward the nose.

[0127] Position sensor: Using a position sensor or equivalent sensor, it is possible to analyze which chamber or pad is currently positioned in the air duct, based in particular on one of the following position detection principles: barcode scanner, reflector counter, camera recording, protractor, touch probe. The values ​​of the corresponding sensor are processed by a processing unit.

[0128] For example, with a barcode scanner, a barcode is attached to each chamber individually.

[0129] For example, in a reflector counter, each chamber has a reflector which can be detected by a light beam and identified or counted by the computing unit.

[0130] For example, in a camera recording, the code is processed using image technology.

[0131] For example, with a protractor, the angular position of the drum or the angular position of the corresponding stepper motor is measured.

[0132] For example, in a touch-sensitive system, each chamber has five hemispherical holes arranged in a row, or studs. These are activated by buttons that, like fingertips, sense the current state over the hole or studs, each closing an electrical circuit. Depending on the closure, the software can determine the current state. This method is based on the concept of Braille.

[0133] Capsule or pad: The fragrance capsule is designed to contain only a small amount of liquid or odorous fluid, and only releases the liquid when the capsule shell is damaged. The liquid is absorbed or absorbed by a synthetic or natural carrier material that surrounds the capsule. Due to the physical properties of evaporation, the odor molecules can be released into the environment from or by the carrier. The capsule and the carrier material advantageously form a single unit. Several of these units are housed individually in several chambers, which together form a magazine.

[0134] Container: The container can hold a larger dose of liquid and can be made of a rigid or flexible material. This container can consist of one or more components. This container can be constructed like a syringe, an injection valve, a spray can, a nebulizer, a soap dispenser, a flexible bottle with a silicone nozzle, or something else. The container is either recessed in the air duct or sits in a chamber that is placed in the air duct. In the recessed version, the air duct has openings and the container has a lid that, when recessed, is flush with the air duct and separates the container from the air duct in an airtight manner. The container is seated in a cylinder. When force is applied to the bottom of the container, it is moved linearly or translationally into the air duct.At the outlet of the containers, there is also a carrier material that can absorb the escaping liquid. The container can contain a pressure equalization valve.

[0135] The liquid is transported out of the container and absorbed by the carrier material, from where it is released. This can be achieved by various means, e.g., by transferring energy into the liquid. This energy is introduced, for example, through heat, vibration, or pressure. Heat (thermal energy) can be generated, for example, by a diode or heating elements. Pressure can be applied, for example, to a piston in the container or to the container itself. Vibration is advantageously transmitted to components such as a porous membrane or a plate using an electric motor or a piezoelectric effect.

[0136] The container advantageously has a closed opening which can be expanded by pressure to such an extent that the liquid can escape from the opening.

[0137] The capsules or containers are located in a magazine, which may have a belt, a drum, and / or a disc. This magazine contains many containers, capsules, or pads. The capsules are only burst or broken open when the respective fragrance is to be emitted, or the liquid (odor fluid) is only expelled from the corresponding container when the respective fragrance is to be emitted. The magazine is mounted on a rotatable support and is set in motion, e.g., by an electric motor or manually.

[0138] Magazine: As described elsewhere in the present disclosure, different types of magazine can be realized. For example, the magazine has a plurality of chambers in which the odorous substances are stored. Each chamber is advantageously only connected to the air duct individually or at most in pairs with another chamber. The chambers as such can form subsections of an air duct. Advantageously, the magazine is embedded in a separate housing so as to be rotatable and is moved or positioned by an electric motor or manually, e.g. by rotation. For example, the chamber has at least one inlet and at least one outlet opening through which the air, which flows through an air duct into the inlet opening and absorbs the volatile odors in the chamber, can be conveyed out through the outlet opening to be conveyed further to the nose. The air is thus aromatized by fragrances which are in a capsule orpad or container in liquid or solid form.

[0139] For example, the capsule or pad is airtight and is burst by pressure. The pressure is generated, for example, by a push-pull motor (hammer-anvil principle). The anvil or stop is integrated into the air channel, preferably in the area of ​​the activation point. The capsule or pad can also be burst by rollers. A relatively thick wall can be provided at the capsule position, and a constriction, a plunger, or a roller can be present in front of the end position of the fragrance chamber, which causes the capsule to burst at the appropriate moment (activation). This releases a fresh fragrance at a precisely pre-determined time. Liquid can be absorbed by a carrier material to then enable the transition into the gas phase (release).

[0140] The respective capsule can also be broken open by a collision with an obstacle and / or by a particularly tight radius of curvature, i.e., in the sense of a geometrically determined activation. For example, an obstacle is firmly integrated into the rotation area of ​​a drum of the magazine, particularly in such a way that a collision is caused during the rotation of the drum (particularly due to the embedding of the capsule) and the capsule is broken open.

[0141] Optionally, the capsule is embedded in a non-absorbent (carrier) material. The air stream then flows against, around, or through the carrier material, allowing the volatile fragrances to be transferred into the air. Pressure differences caused by the air flow can promote a relatively rapid transition of the fragrances into the gas phase, especially with decreasing vapor pressure. Such capsules can be used equally well with a ring drum, disc drum, or tape reel.

[0142] It is advantageous for the carrier material surrounding the capsule to be coated with a separating layer that cannot absorb liquid. This prevents the odor fluid (the capsule's contents) from reaching the rollers or plungers. The rollers and plunger only touch this separating layer. This means that only the carrier material is exposed to the liquid.

[0143] Magazine, in particular a drum magazine: A magazine designed as a drum magazine has, for example, two annular disks which both have the same axis of rotation. The following design has proven advantageous: These disks are spaced apart and are connected to each other, for example, by rectangular plates. The plates are aligned with the axis of rotation of the two disks and are the same distance from each other. These plates serve to stabilize the drum and create several chambers within the disks. The containers or capsules or pads are integrated into these chambers. An attachment containing the capsules or containers can be attached through openings in the upper and / or lower disk. These openings are arranged between the plates. The air flow can flow axially to the fan through the additional opening.This drum magazine can be placed around the propeller housing or at another location within the device's housing. This drum is driven by an electric motor, directly or indirectly via gears, V-belts, rubber cords, and / or chains. The discs can be toothed (positive coupling for rotary actuation). The drum can be made of various materials and is / is inserted into a housing. The drum has sliding surfaces or plain bearings that allow smooth rotation. Its design is similar to that of a fan impeller.

[0144] Magazine with a disc drum: In this variant, the disc can be placed under the propeller ring, particularly to allow for a particularly compact device design. This allows air to be both drawn in and expelled axially. This disc magazine can be placed around the propeller housing or at another location on the device housing. In this variant, the air is first expelled radially from the fan before being axially passed through the chamber of the disc. The disc is advantageously designed in a ring shape. The same mechanisms as for the ring drum can be used.

[0145] Magazine with a tape reel: The tape reel can be constructed, for example, like a photo reel for a mechanical camera. The tape is wound in a can and has openings at the top and bottom edges that serve to unwind the tape reel from the can, e.g., using meshing gears, and wind it onto another reel. Winding can also take place inside the can. The unwinding and winding cans can also be provided as a single component. Only scent capsules (pads) are used in the tape reel. The same mechanisms as for the ring drum can be used.

[0146] Alternatively, a so-called chip emitter can be provided: The chip emitter is constructed similarly to a chip. The containers with the fragrances or pads are arranged on a circuit board and are electronically controlled to release the volatile fragrances. The emitters can be integrated directly onto the container, or the emitters and containers can be located on a separate circuit board, connected to each other by a hose or duct, with the emitter board being arranged in the air duct and the container board outside the air duct. At least one container is connected to an emitter. Several containers can also be connected to one emitter, e.g. to facilitate a fragrance mixture. The release occurs through the addition of energy, e.g. using heating wires or rods. These heating elements can be heated directly by a current flow or indirectly by induction.In addition, small power diodes or lasers can generate heat to enable evaporation.

[0147] Furthermore, vibrations of a plate, as is common in nebulizers, can release molecules. The vibrations are triggered, for example, by piezoelectric, acoustic, or electromechanical effects. These effects can excite membranes or plates to vibrate, and the release can occur in a very precisely predefined manner.

[0148] A design comprising a so-called odor printer is also feasible: Similar to a printer cartridge, which has many nozzles, the carrier liquid is sprayed onto an absorbent material or directly into the air flow using an odor printer. However, unlike an inkjet printer, the odor printer has many chambers with many different odors in one cartridge. Via a deflection roller, the corresponding section is moved, in particular rotated, into an / the air duct in order to allow the evaporation / release of the liquid into the air flow. The carrier material, e.g. paper, can be wound up from another roll. The liquid is applied to the carrier material by a piezoelectric oscillator, a pump, or a heating element. The carrier material has at least two layers.The absorbent material is supported by a tear-resistant layer that cannot absorb liquid. The printer can also inject the liquid directly into the air duct. A diffuser promotes the evaporation rate. Individual printing of a carrier material, which is placed individually in the air duct, is also possible.

[0149] Variant based on an application principle: Here, the liquid is arranged in a container that has a ballpoint pen refill, a paintbrush head, or a fountain pen as the outlet element. The liquid should have such a high viscosity that it cannot drip out. The carrier material, which is located in a small housing, is moved into the air duct, for example, electromagnetically. During this process, it rubs against the outlet element and absorbs a small amount of the liquid. By repeatedly rubbing against the elements, the liquid film on the carrier material increases, and thus also the odor release; in this respect, the process is also easily scalable. Application based on injection is also feasible.

[0150] Variant with linear drum: In a version with a linear drum, several hollow cylinders are arranged in a row, individually or in groups, inside the drum. The containers are inserted into these hollow cylinders. Each container contains a comparatively large quantity of liquid. This also makes it possible to use this magazine more often. The container can be rigid or flexible. Both the rigid and the flexible variants can have components integrated which release the liquid into the air space by heating, vibrating, spraying or dripping. With the flexible variant, the liquid can also be expelled by means of pressure and leakage. This pressure is generated, for example, by an electric motor which drives a camshaft or needle shaft. Another variant is a linear motor. Here, a hammer is combined with a roller which presses a rotatably mounted cylinder against the container.In both variants, an absorbent material is provided at the outlet element to release the fragrance molecules in the air flow path.

[0151] The container can also be designed as a small spray can. The spray can is placed inside a hollow cylinder. An electromechanical lever pushes in a valve, and a fine mist is expelled from the can in the form of an aerosol.

[0152] In this respect, the invention can also be implemented in the context of the following features: Magazine advantageously comprising a revolver drum (ring-shaped) with container or capsules (container for multiple use, capsule for single use), furthermore a plunger (mechanical activation) either perpendicular to the rotation axis or parallel to the rotation axis (activation by pressure force), and / or in the form of a linear magazine, individually loadable or predefined, with fragrance container (spray can, nebulizer, vaporizer, or a type of infusion bag in the container with drop dispensing), and / or comprising a printer (ring-shaped, positioning e.g. as with revolver drum) with printer cartridge (e.g.Piezo or heating evaporator principle), optionally also with a piston which exerts pressure on the containers via a motor, and / or having a cassette, wherein the air flow can be generated by a fan and / or a pump, wherein a fan propeller is advantageously removable and designed with an activated carbon filter, wherein an electric fan (2 in 1) can be provided. For example, the device is arranged in glasses with an air duct and / or nozzle or tube (foldable or attachable, e.g. telescopic, or deformable) and designed to be individually adjustable in size for personal use.

[0153] From the present disclosure, it is therefore clear to those skilled in the art that the manner in which the respective fragrance is released can be realized in different ways. With a more robust mechanical design, the variants of the magazine described here have proven particularly advantageous, as they also allow for manual activation by positioning the respective pad. With the integration of more in-depth electronic functions, the control / regulation can be implemented particularly effectively and precisely, for example, when optimization with regard to the released quantity and / or the respective emission time window is particularly important.In other words: The conceptual distinction based on the embodiments described here can also be made by a person skilled in the art, taking into account the relevant cost factor (fewer motors, lower costs, possibly eliminating a control unit or at least some of the control / regulation functions). A rotary motor with a communication unit (transmitter and receiver) is user-friendly and safe for magazines with a revolving drum, especially when implemented for odor cinemas or odor TV (synchronization of the various odors with the currently displayed image; rotation start or activation / release, e.g., depending on an infrared, Bluetooth, or Wi-Fi signal).The printer is most likely more expensive to produce than drum cartridges, particularly since a separate nozzle is provided for each scent, particularly with pressure compensation or with a flexibly deformable chamber with a fragrance medium (deformation under negative pressure). A revolver drum is advantageously designed as a disposable item (single use), whereas the printer can be used repeatedly. The revolver drum can advantageously be loaded by the respective individual and is therefore easier to customize than, for example, a printer, which can only be customized, replaced, or refilled at greater expense. For example, inkjet printer cartridges are provided which have an interior sponge soaked with ink (maintenance by the user, possibly therefore only advantageous for complete systems that are operated by service providers such as, for example,operators of smell cinemas are maintained and individually equipped).

[0154] Summary: When generating odors / fragrances, particularly in coordination with audiovisual media, the challenge is to make the respective odor perceptible in a timely manner or within as narrowly predefined time windows as possible, and then allow it to evaporate again. An olfactory emission device is provided, configured to emit a plurality of odors / fragrances in the area of ​​or directed at at least one nostril of an individual during mobile use, comprising a fan unit, a motor, and a magazine with a plurality of odor pads. The respective odor pad is activated by manual and / or motorized positioning at a designated activation point.

The respective odor pad 13 can be embedded in a cushion or carrier material 15 (preferably textile), depending on the manner in which the fragrance release is desired (e.g.,Transition into the gas phase by convection, and / or forced release by means of an emission unit, e.g., based on piezoelectric effects. The emission device 10 has at least one housing 18, in which, for example, the magazine 14 and the feed 17 (gas, fluid) are accommodated, including at least one inflow channel 17.1 and a channel section 17.2 surrounding the activation point 16. The emission device 10 can further be equipped with a control / regulation unit 20 and a wireless communication module 30, e.g., configured for a near-field communication protocol. Furthermore, an energy storage device 40 can be provided for mobile use.

[0158] A receiving cavity 10.2 is formed on a bracket 10.1 of the olfactory emission device 10 or of an object 3 comprising the same, which receiving cavity is designed to receive the at least one fan unit and further components effective for the emission.

[0159] Using the magazine 14, kinematics can be specified for a predefined movement path BP13 of a respective odor pad, at least up to the activation point and optionally also beyond. In the area of ​​the activation point, activation / release can also be predefined / forced based on geometric conditions, e.g., by means of a contour having a comparatively small radius of curvature KR16, which causes the respective pad 13 to break open.

[0160] The invention is advantageous in connection with the Fig. 37 steps S1 to S4 are implemented / can be implemented (whereby step S4 remains optional).

[0161] In the following, special features of the invention are explained with reference to individual figures or embodiments.

[0162] In Fig. 1 illustrates an embodiment of a cassette 14.2.

[0163] In Fig. Figure 2 illustrates an embodiment of a revolver drum 14.1 or ring drum. The image (or view) top left shows the device without the cover. The inserted and replaceable ring drum is driven by a stepper motor. The ring drum is hermetically sealed by an inner and outer wall. The outer wall has a groove that serves to rotate the ring drum by means of an electric motor. The air flow is realized by a fan in an axial, radial, or diagonal design and is passed through ducts. The outlet can be designed in three areas or in three directions. An additional outlet and duct with an outlet on the rear of the housing serves as a bypass for ventilation, e.g., of the individual's skin, spectacle lenses, and / or eyes. This outlet can be closed or opened by a sliding flap. The device also accommodates electronic components, e.g.Communication, control, and processing electronics, and the power supply. The top center image shows the front view with the eye ventilation bypass and the conditioned air outlets. The top right image shows the rear of the device housing with the bypass channel and its outlet with a sliding flap. The bottom left image shows the device cover with its air inlets and the opening flap for inserting the ring drum. The flap is opened by a hinge. The flap is secured to the device housing when closed by a force-locking and / or positive connection. The bottom right image shows the ring drum. The edge of the top and bottom discs is designed as a gear. The top ring has openings for the inserts of the odorant carriers (pads). The carrier material for the odorants is arranged separately on a third ring.The supports can also be integrated as part of the ring drum, eliminating the need for a third disc. Thus, .

The empty chamber directs the generated air flow into the duct, before flowing through the chamber equipped with scent pads, which is connected to or provided with the outlet. With this design, the height of the device housing is comparatively low, yet it is comparatively long. The air duct can also be omitted or made smaller with this design, particularly since the system is self-contained and the air flows through to the outlet. The image bottom right and middle right shows the device in a state in which each chamber is equipped with scent pads.The center right image shows the side view, and the bottom right image shows the top view. The airflow is guided over the ring drum into the center of the ring drum, from where it flows through an opening through the fragrance chamber to reach the outlet. Switching from fragrance chamber to fragrance chamber is achieved by rotating the ring drum, e.g., using an electric motor. Thus, the figure shows...
