Description

[0001] The present invention relates to a device for dispensing, evaporating and / or vaporizing an active ingredient, an arrangement of such a device with at least one active ingredient, and the use of a carrier and / or a carrier vessel in such a device and / or such an arrangement.

[0002] Active ingredients can include, for example, fragrances, perfumes, inhalable medications, odor neutralizers, and similar substances. The following section outlines the state of the art using fragrances as an example. The same applies generally to active ingredients.

[0003] It is known from the prior art to design various devices for the release, evaporation and / or vaporization of a fragrance in an interior space or living space, whereby a fragrance is released into the environment to neutralize or mask unpleasant odors, or simply to create a pleasant indoor climate.

[0004] For example, it is known to set up appropriate devices in interiors or living spaces to cover up unpleasant odors and / or to spread a fragrance in the interior to provide a pleasant olfactory experience.

[0005] For this purpose, stationary or portable devices are usually placed indoors or in a living space, which distribute the fragrance into the surrounding area through release, evaporation, and / or vaporization. Reference can be made, for example, to the Austrian patent AT 523 395 B1.

[0006] However, this has the disadvantageous characteristic that the fragrance is usually only intensely released in the immediate vicinity of the device, while more distant parts of the interior cannot be efficiently reached by the device and thus by the fragrance.

[0007] This results in an uneven distribution of the fragrance in an interior space or living area, which either leads to an unpleasant odor experience near the device because the fragrance is released in too intense a manner, or, at a greater distance from the device, results in the fragrance being barely perceived and any existing unpleasant odors not being masked.

[0008] Another disadvantage of known devices for dispensing, evaporating and / or vaporizing a fragrance is that such devices are usually operated continuously, which means that a targeted and therefore efficient response to a need is not possible.

[0009] Thus, the continuous release of fragrance into an interior space, which, for example, is not supplied with fresh air for an extended period of time, creates an intense odor sensation for an occupant of the room, which may be perceived as unpleasant.

[0010] On the other hand, it may be the case that with high air circulation or fresh air supply into the interior, the release of fragrance is not high enough, so that a desired pleasant smell does not come to the fore or unpleasant odors, for example, cannot be adequately masked.

[0011] German utility model DE 20 2021 104 216 U1 describes a device for scenting a room, comprising a scent reservoir and a scent release unit with at least two scent elements, each of which has a cavity. The cavity is in fluidic communication with the reservoir. The two scent elements have an outlet opening for the release of the scent from the respective scent element.

[0012] Document WO 2012 015 475 A2 discloses an air freshening device that can be attached to the ventilation openings of heating, ventilation, and air conditioning systems to distribute fragrances via airflow. The fragrances are released into the airflow by means of flat fragrance elements soaked in a fragrance liquid. The fragrance elements are arranged essentially along the defined airflow direction, thereby achieving a significant diffusion effect with minimal disruption to the system airflow.

[0013] US patent application US 2021 356 147 A1 describes an air freshening device for attachment to a forced ventilation opening. The air freshening device comprises a ventilated housing, a container holding a dispersible fragrance material, and a fragrance adjustment mechanism for adjusting the amount of fragrance material dispersed into an airflow exiting the forced ventilation opening.

[0014] German patent application DE 10 2009 006 192 A1 discloses a fragrance device for the interior of a vehicle. The fragrance device comprises a container for a fragrance substance, which is housed within a space enclosed by a receiving device. The receiving device includes at least one air inlet opening and one air outlet opening.

[0015] The object of the present invention is to provide a device for the release, evaporation and / or vaporization of an active ingredient, with which the disadvantages of the prior art described above are at least partially improved and / or the release, evaporation and / or vaporization of the active ingredient into an interior space is improved and / or the release, evaporation and / or vaporization of an active ingredient can be adapted more efficiently or in a more targeted manner to environmental conditions.

[0016] This problem is solved by a device for dispensing, evaporating and / or vaporizing an active ingredient with the features of claim 1, with an arrangement of such a device and at least one active ingredient with the features of claim 17 and a use of a carrier and / or carrier vessel in such a device and / or such an arrangement.

[0017] According to the invention, a device for dispensing, evaporating and / or vaporizing an active ingredient, in particular a fragrance, into an interior space comprises the following: - at least one fastening device designed for attaching the device to an outlet element of an indoor ventilation system, - at least one storage device for storing the active ingredient and - at least one opening by means of which the storage device is exposed to an airflow from the outlet element when the device is attached to the outlet element.

[0018] By attaching the device to an outlet element of a ventilation system in the interior, it is possible to directly couple the device to the ventilation system of the interior, so that the ventilation of the ventilation system of the interior is used to release or distribute an active ingredient into the interior, so that the entire airflow conveyed into the interior is supplied with the active ingredient and thus a constant distribution of the active ingredient throughout the entire interior is permitted.

[0019] Furthermore, the airflow conveyed into the interior via the ventilation system can be supplied with the active ingredient, thus achieving a homogeneous distribution.

[0020] Furthermore, the coupling with the ventilation system of the interior allows for a discontinuous release of the active ingredient, whereby when an airflow is supplied to the interior, the active ingredient is released into the airflow, whereby this can be adapted to the volume flow, so that in the case of a low or absent airflow the supply of active ingredient can also be reduced or suspended accordingly.

[0021] Furthermore, compared to the prior art, the device according to the invention allows the release, evaporation and / or vaporization of the active ingredient to be adjusted more efficiently, so that the active ingredient is released more effectively into the interior and, if necessary, the amount of active ingredient can be saved.

[0022] The storage device does not need to be placed, or need to be placed, in the direct airflow exiting the outlet element. For example, according to the invention, the release of the active ingredient can already be achieved by exposing the active ingredient to the airflow in such a way that it is released from the device according to the invention.

[0023] This can be done, for example, by utilizing the Venturi principle, although this is not absolutely necessary within the scope of the invention.

[0024] Active ingredients can be understood as any substances that achieve a desired effect in the interior, for example in the form of a fragrance or a medicinal effect.

[0025] Active ingredients can therefore include, for example, fragrances, perfumes, medications, inhalants, odor-neutralizing substances or similar products.

[0026] A device according to the invention can also be used in already known embodiments of the prior art and can be installed subsequently.

[0027] Advantageous embodiments of the invention are defined in the dependent claims.

[0028] It may be provided that at least one opening is arranged on a side of the device facing the outlet element of the ventilation system in the state of use.

[0029] The term "in use" refers to a mounted state of the device via at least one fastening device on the outlet element of the ventilation system.

[0030] Preferably, the fastening device has at least one holding element, preferably one with a magnet, which is designed to fasten the device to the outlet element of the ventilation system, preferably detachably.

[0031] A fastening device, preferably comprising a magnet, provides a simple way to attach or remove the device for delivering an active ingredient from an outlet element of the ventilation system, thereby also allowing the device to be arranged pleasantly and discreetly in an interior space and / or living space, so that it does not become an unpleasant nuisance to a user or a person moving within the interior space, does not get in the way or even visually or audibly noticeable.

[0032] It may be provided that at least one retaining element is designed as a projection, preferably cylindrical, extending from the device.

[0033] At least one, preferably centrally arranged, intake opening can be provided, which is designed to connect the storage device fluidically with the environment.

[0034] Thus, it can be provided that ambient air is supplied to the at least one storage device via the at least one intake opening, in which the ambient air is treated with an active ingredient in the at least one storage device, and subsequently the ambient air treated with the active ingredient leaves the device again via the at least one opening and is supplied back to the interior.

[0035] It may be provided that the at least one intake opening is arranged on a side of the device facing away from the at least one opening.

[0036] Preferably, the at least one opening connects the at least one storage device to the environment of the device in a fluid-technical manner and is particularly preferably designed as at least one bore and / or as a through-hole in the device.

[0037] It may be provided that the at least one storage device has at least a storage volume which is designed to accommodate the active ingredient, a vessel carrying the active ingredient and / or a carrier receiving the active ingredient.

[0038] Preferably, at least one adjusting device is provided which is designed to vary the degree of opening of the at least one opening.

[0039] It can be provided that the at least one adjusting device has a perforated disc, wherein the disc is arranged in contact with the at least one opening, wherein by a relative movement of the disc to the device the at least one opening can be at least partially covered in order to vary the degree of opening of the at least one opening.

[0040] By means of a suitable adjustment device, the degree of opening of the at least one opening can be varied in order to, for example, change the volume flow passing through the at least one opening. By changing the volume flow passing through the at least one opening, the dosage of the material can also be controlled, thereby allowing the intensity of the active ingredient release from the device to the interior to be controlled or regulated by the at least one adjustment device.

[0041] Preferably, the device may have an openable lid designed to release the at least one storage device arranged inside the device to the environment of the device.

[0042] A suitable openable lid can therefore preferably provide a means of accessing the storage device and the active ingredient to be placed therein, so that a user can conveniently place the active ingredient in the at least one storage device, refill it and / or change it.

[0043] It may be intended that the lid - which has at least one opening and / or - can be detachably connected to the device by means of a fastener, preferably a bayonet fastener.

[0044] Preferably, the device has a symmetrical, preferably cylindrical, outer contour.

[0045] According to the invention, the device has at least one guiding device, preferably designed as a separate component, which guiding device in the state of use is designed on the ventilation element to guide an airflow from the outlet element to the device in such a way that an airflow from the storage device can be caused via the Venturi principle through the at least one opening.

[0046] The at least one guiding device thus creates the possibility that an airflow is passively conveyed in the device via the airflow of the ventilation element.

[0047] Thus, the release of the active ingredient can be passively adjusted to an airflow supplied to the interior by the ventilation element, resulting in automatic regulation of the intensity of the release of the active ingredient, which allows for particularly efficient control of the release of the active ingredient.

[0048] It may be provided that at least one guide device is designed in a disc shape and / or, in a state of use of the device, overlaps at least partially with an outlet opening of the outlet element.

[0049] It is particularly preferred that the disc-shaped guide device has a circular, oval, rectangular and / or flower-shaped outer contour.

[0050] Preferably, the at least one opening in a state of use of the device is arranged on the outlet element on a side of the device facing the outlet element, preferably centrally with respect to the disc-shaped at least one guide device.

[0051] Furthermore, protection is sought for an arrangement of a device according to the invention and an active ingredient, preferably a fragrance, wherein the active ingredient is arranged in the at least one storage device.

[0052] Preferably, it can be provided that the active ingredient - is stored in a carrier, wherein the active ingredient can be released from the carrier by evaporation, vaporization and / or mechanical influences and / or - is stored in a carrier vessel for the liquid, solid and / or gaseous storage of the active ingredient, wherein the active ingredient can be released through an opening in the carrier vessel, wherein the carrier and / or the carrier vessel is arranged in the at least one storage device.

[0053] It is also conceivable to implement designs in which at least one active ingredient - preferably in liquid form - is provided directly in the at least one storage device.

[0054] Highly viscous active ingredients or solid substrates that release an active ingredient or substrates for the absorption of an active ingredient are also conceivable and applicable in one design variant.

[0055] Potential carriers are made of materials capable of absorbing at least one active ingredient, which is then absorbed or carried through the pores of the carrier. However, materials that can absorb the active ingredient through a chemical reaction or physical action and are also capable of releasing it again are also conceivable.

[0056] Furthermore, protection is sought for a use - a carrier in which an active ingredient is stored, wherein the active ingredient can be released from the carrier by evaporation, vaporization and / or mechanical influences and / or - a carrier vessel designed to receive a liquid, solid and / or gaseous active ingredient, wherein the active ingredient can be dispensed through an opening in the carrier vessel in a device and / or arrangement according to the invention.

[0057] Further examples, advantages and details of the invention are illustrated in the figures and the following figure description, which show: Fig. 1 a sectional view of an embodiment of a device according to the invention, Fig. 2 a perspective view of the exemplary embodiment of the Fig. 1, Fig. 3 an exploded view of the device made of Fig. 1 or Fig. 2, Fig. 4 a state of use of the embodiment of the Fig. 1, Fig. 5 a perspective view of the Fig. 4, and Fig. 6 a sectional view of the Fig. 5.

[0058] Fig. Figure 1 shows an embodiment of a device 1 for the release, evaporation and / or vaporization of an active ingredient in a sectional view.

[0059] This embodiment of device 1 is characterized by the Fig. 2 shown in a perspective view and by Fig. 3 in an exploded view, in which the individual parts of the device 1 are shown in more detail.

[0060] The device 1 of this embodiment has a base body 14, wherein the storage device 4 is formed in the form of a storage volume for receiving the active ingredient via the geometric shape of the base body 14.

[0061] The base body 14 is closed via the lid 11, the lid 11 being detachably connected to the base body 14 by means of the closure 12.

[0062] In this embodiment, the closure 12 of the lid 11 with the base body 14 of the device 1 is designed as a bayonet closure, whereby a closing or opening of the closure 12 can be carried out by a rotational movement of the lid 11 relative to the base body 14 of the device 1.

[0063] In this embodiment, the lid 11 has a plurality of openings 5, by means of which the storage device 4 is fluidically connected to the environment.

[0064] The lid 11 of the device 1 further has the fastening device 2, wherein the fastening device 2 extends from the lid 11 over the cylindrically designed retaining element 7 in a longitudinal direction.

[0065] At one end of the retaining element 7, the fastening device 2 has a magnet 6 for attaching the device 1 to an outlet element 3 of a ventilation system 18 (here, reference should be made to the Fig. 4 to 6 referred to).

[0066] Furthermore, the exemplary embodiment of the Fig. 1 to 3 of a device 1 for dispensing, evaporating and / or vaporizing an active ingredient, a perforated disc 10 connected to the lid 11.

[0067] This perforated disc 10 rests against the lid 11 and can be rotated towards it.

[0068] In this embodiment, the adjusting device 9 is formed by the perforated disc 10, wherein the perforated disc 10 has the same hole pattern as the cover 11 with respect to the openings 5.

[0069] When the perforated disc 10 is in contact with the surface of the lid 11, the perforated disc can be rotated over the illustrated attachments (which can also be called ears), whereby the position of the openings in the perforated disc 10 changes relative to the openings 5 ​​in the lid 11, thus allowing the degree of opening of the openings 5 ​​to be varied.

[0070] Furthermore, the device 1 for dispensing, evaporating and / or vaporizing has a guide device 13, which guide device 13 is connected to the base body 14 of the device 1 via the retaining elements 15.

[0071] The device 1 further has an intake opening 8 arranged on the base body 14, which can direct ambient air from the interior into the interior of the device 1 and thus to the storage device 4 via the guide device 13 and a central bore on the guide device 13.

[0072] For a more detailed explanation of the function of device 1 for the release, evaporation and / or vaporization of an active ingredient, reference is made to the Fig. Reference is made to figures 4 to 6, which represent a state of use of the device 1 at an outlet element 3 of a ventilation system 18.

[0073] This shows Fig. 5 den in Fig. Figure 4 shows the state of use of the device 1 in a perspective view.

[0074] Fig. Figure 6 shows the operating state of device 1 from the Fig. 4 and Fig. 5 in a perspective cropped representation.

[0075] The ventilation system 18 of this embodiment is arranged in the ceiling 16 of an interior space 17, whereby an airflow 19 can be supplied to the interior space 17 via the ventilation system 18.

[0076] This airflow 19 can, for example, be directed from the outside into the interior 17 via a filter system and, if necessary, a heater designed as a heat exchanger.

[0077] Before entering the interior space 17, an outlet element 3 is provided, which radially redirects the airflow 19 of the ventilation system 18 in order to prevent direct airflow towards people below the outlet element 3 and thus distributes the airflow close to the ceiling 16.

[0078] Such outlet elements are known from the prior art, for example, under the name "ventilation valve" or "air outlet valve" of a ventilation system 18.

[0079] In the illustrated embodiment, the following is located at such an outlet element 3 of the ventilation system 18: Fig. 4 to 6 the device 1 for the release, evaporation and / or vaporization of an active ingredient is arranged via the fastening device 2.

[0080] More precisely, the device 1 is held on the metallic outlet element 3 via the holding element 7 and the magnet 6.

[0081] When the airflow 19 of the outlet element 3 is directed into the interior 17, it is guided via the guide device 13 in such a way that, by means of the Venturi principle, an airflow 20 is conveyed out of the storage device 4 via the openings 5 ​​of the device 1.

[0082] This creates an airflow from the interior 17 via the intake opening 8 into the storage device 4, whereby this airflow in the storage device 4 is supplied with the active ingredient by release, evaporation and / or vaporization of an active ingredient which is arranged in the storage device 4.

[0083] After the airflow in the storage device 4 is treated with the active ingredient, it is conveyed further via the openings 5 ​​and the guide device 13 and released again into the interior 17.

[0084] This procedure makes it possible to passively direct an airflow through the device 1 for the release, evaporation and / or vaporization of an active ingredient by utilizing an existing airflow 19 of a ventilation system 18.

[0085] The openings 5 ​​are arranged on the side of the device 1 facing the outlet element 3 in a state of use.

[0086] The intake opening 8, on the other hand, is arranged on a side of the device 1 facing away from the openings 5 ​​in order to draw in an airflow from the interior 17.

[0087] The arrangement of the central intake opening 8 and the multitude of openings 5 ​​above the storage device 4 directs the airflow specifically over the storage device 4.

[0088] The openings 5 ​​connect the storage device 4 to the environment of the device 1 in a fluid-technical manner, whereby these openings 5 ​​are, strictly speaking, designed as bores in the lid 11.

[0089] As mentioned, the storage device 4 of this embodiment is designed as a storage volume, in which an active ingredient can be directly filled or a carrier can be arranged which absorbs the active ingredient and can release it again through evaporation, vaporization and / or mechanical influences.

[0090] It would also be conceivable to arrange a carrier vessel in the storage device 4, wherein the active ingredient is present in liquid, solid or gaseous form in the carrier vessel, and the active ingredient could in turn be guided through the openings 5 ​​via the carrier vessel.

[0091] By means of the adjusting device 9, more precisely: the rotatability of the perforated disc 10 (which could also be called the "iris disc") relative to the base body 14, the intensity of the drug release can be adjusted by adjusting the degree of opening of the openings 5.

[0092] The removable lid 11 of the device 1 allows the storage device 4 to be exposed to the environment in order to refill, exchange and / or remove the active ingredient in the storage device 4.
