Description

[0001] The invention relates to a room fragrance device according to the preamble of claim 1.

[0002] According to the state of the art, so-called fragrance sticks made of rattan or willow are known for the purpose of room fragrance, as discussed, for example, in publications WO 2016 / 150854 A1 and WO 2018 / 072043 A1. With these fragrance sticks, a liquid containing fragrance is absorbed by capillary action and released into the surrounding environment through the pores of the sticks, thereby influencing the room fragrance. One end of the fragrance stick is inserted into a container filled with the fragrance-containing liquid. The opposite end of the fragrance stick protrudes from the container, where the fragrance is then released into the room air through evaporation of the liquid.

[0003] Natural fragrance sticks, made from materials such as rattan or balsa wood, have the disadvantage that their size depends on the availability of the natural raw material. For example, a size desired by the user that exceeds a standard tabletop size can be prohibitively expensive or may even be impossible to achieve. Furthermore, a disadvantage of conventional natural fragrance sticks is that they are generally designed for a single, specific scent, and switching to a different scent with the same stick is either not possible or does not work satisfactorily. Another drawback is that commercially available fragrance sticks are disposable items, at least after a certain period of use.

[0004] DE 10 2011 101 295 A1 discloses a device for evaporating liquid. This device comprises a container with a filling chamber that can be filled with an evaporable liquid, and a capillary element with a receiving area extending down to the fill level of the evaporable liquid and with a discharge area extending above the fill level of the evaporable liquid, serving to release the evaporable liquid into the ambient air. The capillary element of this device is made of wood and has a plurality of continuous and / or branched and interconnected capillary channels within it, which open at the surface of the capillary element.

[0005] From DE 10 2007 026 603 A1, a device for evaporating liquids containing essences is known. This device comprises a container into which the liquid can be introduced, and an evaporation element by means of which the liquid can be removed from the container and released into the ambient air. The evaporation element has an absorbent, flat element and is made of Modal.

[0006] A product called "Mana Diffuser Crème" is available commercially. This is a capillary diffuser vase with a Sola wood flower design for room fragrances and essential oils. The product consists of an evaporation element shaped like a flower, with a cotton stem or wick. To use this product, the cotton stem or wick of the flower is immersed in a vase filled with the liquid to be evaporated. Due to capillary action, the liquid rises from the vase through the cotton wick and evaporates from the surface of the flower-shaped element, thus releasing it into the surrounding air. In this product, the function of the evaporation element is fulfilled solely by flower-like surface elements made of Sola wood, which are connected to the cotton stem or wick at its end.

[0007] Accordingly, the invention is based on the objective of optimizing the scenting of rooms in buildings using simple means.

[0008] The above problem is solved by a room fragrance device with the features of claim 1. Advantageous embodiments of the invention are defined in the dependent claims.

[0009] A room fragrance device according to the present invention serves to release a fragrance into the environment, particularly in the form of enclosed spaces in buildings. The room fragrance device according to the invention comprises an evaporation body with a plurality of fibers, wherein the evaporation body exhibits capillary action and is suitable for receiving fragrances in liquid form. The evaporation body is made of a textile material or comprises at least one textile material. The invention is characterized by an elongated rod-shaped element, wherein the evaporation body (12) in the form of the textile material is attached to an outer circumferential surface of the rod-shaped element, so that the evaporation body is exposed to the environment, and wherein the evaporation body in the form of the textile material completely encloses the rod-shaped element in a plane perpendicular to its longitudinal axis.

[0010] According to an advantageous embodiment of the invention, the room fragrance device comprises a container for a liquid containing at least one fragrance. The evaporation element, in the form of the textile material, can be inserted into an opening of the container with its lower end and protrudes from the opening of the container with its upper end.

[0011] In the intended use of the room fragrance device according to the invention, the evaporating element is inserted at one end into the container, which is filled with an aromatized liquid or the like. Due to capillary action, the liquid rises up or within the evaporating element towards its opposite end, which protrudes upwards from the container. As the liquid evaporates from the upper, exposed part of the evaporating element, the fragrance or odorant contained in the aromatized liquid is released into the surroundings, thus achieving the desired room fragrance.

[0012] The invention is based on the essential insight that the evaporative element fulfills a dual or integrated function: On the one hand, thanks to the capillary action resulting from the numerous associated fibers, the evaporative element transports liquid from its lower end along its longitudinal axis towards its upper end automatically, without the use of additional energy or technical aids such as pumps or the like. Furthermore, as its name suggests, the evaporative element also serves the purpose of allowing the liquid to evaporate from it to the outside, thereby releasing the fragrances or odorants contained in the liquid into the surrounding environment.

[0013] For the purposes of the present invention, the feature "textile material" is understood to mean any material with a plurality of fibers, consisting of fibers connected or interwoven together. According to the invention, any woven or knitted fabric constitutes a textile. The fibers from which the evaporation body is made can consist of natural fibers, synthetic fibers, glass fibers, yarn, thread, natural silk, viscose, man-made fibers, elastic fibers, and / or metal or steel threads.

[0014] According to an advantageous embodiment of the present invention, the evaporation body has a longitudinal extension, wherein the capillary action of the evaporation body is present at least along its longitudinal extension. Advantageously, said capillary action can also be omnidirectional for the evaporation body, i.e., not only along a longitudinal extension, but also in a direction transverse or orthogonal to the longitudinal extension. In this case, it is advantageously ensured according to the invention that a liquid is distributed in various directions within the evaporation body if, for example, an end of the evaporation body comes into contact with the liquid or is immersed in it.If the evaporation body is designed in the form of a stocking, the aforementioned omnidirectional capillary action ensures that the liquid within the evaporation body is transported or distributed evenly not only from its lower end towards the upper end, but also along the circumference of the evaporation body.

[0015] In an advantageous further development of the invention, the evaporation element, in the form of the textile material, can completely cover the outer circumferential surface of the rod-shaped element along its longitudinal extent. Here, the textile material can be designed in the form of a stocking, which is pulled over the supporting rod-shaped element for attachment. In other words, in this embodiment, the stocking-shaped textile material is located on the outer circumferential surface of a rod-shaped element and is suitably supported by it in its longitudinal direction.

[0016] The aforementioned rod-shaped element provides sufficient stability to the evaporation body, which is made of textile material, along its longitudinal axis, by attaching this textile material to the outer circumferential surface of the rod-shaped element. It is possible for the evaporation body, made of textile material, to enclose the rod-shaped element like a stocking. In other words, the evaporation body, made of textile material, completely encloses the rod-shaped element in a plane perpendicular to its longitudinal axis.

[0017] The rod-shaped element can be made of any material, for example wood, glass, stone, metal, plastic, ceramic, plaster, etc. For the purposes of the present invention, the only important characteristic of the rod-shaped element is that the material from which it is made has sufficient inherent stability, resistance to buckling, and thus stability, so that the evaporation element in the form of the textile material can be attached to an outer circumferential surface of the rod-shaped element, for example in the manner of a stocking.

[0018] According to an advantageous embodiment of the invention, the rod-shaped element can be a hollow tube in cross-section, at least in one segment along its longitudinal axis. Advantageously, the rod-shaped element consists of a hollow tube along its entire longitudinal axis. Besides favorable manufacturing costs, such a tubular design of the rod-shaped element also offers the advantage that the weight of the rod-shaped element remains relatively low even with larger dimensions, e.g., a length of more than 50 cm, thus ensuring that the rod-shaped element remains easy to handle.

[0019] The aforementioned possible tubular shape of the rod-shaped element further leads to the practical advantage that the evaporation body in the form of the textile material can be easily pressed into the interior of the tube if the textile material protrudes at the end faces of the tube and can be attached to or in the end face of the tube by means of a plug.

[0020] The possibility that, in the case of a rod-shaped element, the evaporation element in the form of the textile material can be attached to the outer surface of the rod-shaped element as described, also conversely allows for the possibility that, after use of the room fragrance device according to the invention, this textile material can be separated or removed from the rod-shaped element, for example, for cleaning and / or repair, if necessary. In this way, multiple uses of the evaporation element in the form of the textile material are ensured, also in terms of ecological sustainability.

[0021] Given that the fibers of the evaporating element of the room fragrance device according to the invention are not of natural origin, but are part of the characteristic textile material from which the evaporating element is formed or from which the evaporating element can at least partially consist, it is also possible, by means of the present invention, to manufacture the evaporating element in a comparatively large dimension, for example with a longitudinal extent of more than 100 cm, or possibly even larger. If a rod-shaped element is used to support the evaporating element, it is understood that this element is adapted to the longitudinal extent of the evaporating element, for example with the aforementioned length of 100 cm (or possibly even larger). Such a comparatively large dimension of the evaporating element (and possibly even larger)The use of a rod-shaped element (to whose outer surface the evaporation body in the form of the textile material is attached) with a longitudinal extent of, for example, ≥ 100 cm is advantageous when large rooms are to be scented using the present invention, such as an event hall, a hotel lobby, or the like. In this context, it is understood that a container into which the evaporation body is placed with its lower end is also correspondingly large and designed to accommodate the dimensions of the evaporation body.

[0022] In a practical application of the room fragrance device according to the invention, an evaporating element, which is made of a textile material or at least incorporates a textile material and exhibits capillary action due to a multitude of fibers along its longitudinal extent, is inserted with its lower end into an opening of a container filled with a liquid containing a fragrance, with the evaporating element protruding from the opening of the container with its opposite upper end. In this case, the evaporating element is exposed to the environment in a section of its length that lies above the opening of the container and thus outside the container.

[0023] In the practical application of the room fragrance device according to the invention, as just mentioned, evaporation of the liquid is ensured with regard to the evaporation body, at least in the section of its length that is located above the opening of the container and is exposed to the environment, so that in this section of the evaporation body, in addition to the transport of the liquid towards the upper free end of the evaporation body as a result of capillary action, the liquid also evaporates and thus the fragrance and odor substances contained therein are released.

[0024] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0025] The invention is schematically illustrated below with reference to preferred embodiments in the drawing and is described in detail with reference to the drawing. The drawing shows: Fig. 1 a simplified top view of an evaporation body that is part of a room fragrance device according to the invention, Fig. 2a a simplified side view of a rod-shaped element that is part of the room fragrance device according to the invention, Fig. 2b a side view of a room fragrance device according to the invention with its associated evaporation body according to a further embodiment, which is intended for use with the rod-shaped element of Fig. 2a is provided for, Fig. 2c the room fragrance device according to the invention, when the evaporation body according to Fig. 2b on an outer circumferential surface of the rod-shaped element of Fig. 2a is appropriate, Fig. 3 a cross-sectional view of the room fragrance device along line AA of Fig. 2c, Fig. 4 a longitudinal section view of the room fragrance device according to Fig. 2c, Fig. 5 a simplified side view of a container that is part of the room fragrance device according to the invention, Fig. 6 a side view of the container of Fig. 5, if it contains a room fragrance device according to Fig. 2c with one end of it is introduced, and Fig. 7 a perspective simplified room view showing further embodiments of the room fragrance device according to the invention, wherein an evaporation body according to Fig. 1 and a container according to Fig. 5 will be used.

[0026] The following are, with reference to the Fig. Figures 1-7 illustrate and explain preferred embodiments of a room fragrance device 10 according to the invention, which enables the application or distribution of a fragrance, preferably in enclosed spaces of a building. Identical features in the drawing are identified by the same reference numerals. It should be noted that the drawing is simplified and, in particular, not to scale.

[0027] Fig. Figure 1 shows a side view of an evaporation body 12, which is part of a room fragrance device 10 according to the invention (see Figure 1). Fig. 2) is. This evaporation body 12 is designed as an elongated textile, with a lower end 13 and an upper end 14, and a longitudinal extent L 12 , which lies between the upper and lower ends 13, 14.

[0028] The evaporation body 12 is made of a textile material with a plurality of fibers F. In this respect, it is important for the functioning of the present invention that the evaporation body 12 is formed at least along its longitudinal extent L. 12 exhibits a capillary effect. As a result of this capillary effect, it is ensured that if the lower end 13 of the evaporation body 12 comes into contact with such a liquid, it is then continuously transported upwards towards the upper end 14 of the evaporation body 12 without the supply of any additional external energy.

[0029] With regard to the evaporation body 12 according to Fig. 1. It is further noted that the aforementioned capillary action also occurs orthogonally or transversely to the longitudinal extent L. 12of the evaporation body 12. Thus, omnidirectional transport of liquid within the evaporation body 12 is ensured if the lower end 13 comes into contact with liquid. This will be explained in more detail below.

[0030] In practical use of the room fragrance device 10 according to the invention, a container 20 is used which is filled with a liquid containing at least one fragrance or odorant. Such a container 20 is, in principle, simplified to Fig. Figure 5 shows a side view. The liquid, containing at least one fragrance or odorant, is in the Fig. 5 is designated by the reference sign “D”, where the fill level of this liquid D in the container 20 is symbolized by a horizontal dashed line.

[0031] Container 20 (see Fig. 5) has an opening 21 at its upper end. Through this opening 21, it is possible to insert the room fragrance device 10 with its associated evaporation body 12 and its lower end 13 into the container 20. This is explained below with reference to various embodiments of the invention.

[0032] Fig. Figure 7 illustrates, in a simplified manner, a perspective view of a room R in a building, showing two embodiments of the room fragrance device 10 according to the invention. These two embodiments have in common that the evaporation body 12 of the room fragrance device 10 according to the invention is used without any further support or reinforcing elements, but instead only with a suitable holder to which the upper end 14 of the evaporation body 12 is attached. In detail: At the in Fig. In the embodiment of the room fragrance device 10 shown in the right-hand area of ​​Figure 7, a support in the form of a stand 31 is positioned adjacent to or to the side of the container 20. This stand 31 has a lateral extension, the free end of which reaches above the opening 21 of the container 20. Specifically, the evaporating element 12 is held in the room by its upper end 14 being attached to the lateral extension of the stand 31. The positioning of the stand 31 relative to the container is chosen such that the lower end 13 of the evaporating element 12 is inserted through the opening 21 into the container 20 and thus into the liquid D with which the container is filled (see Figure 7). Fig. 5). In this way, the evaporation body 13 of the room fragrance device 10 is immersed with its longitudinal extent L 12suspended vertically in space, wherein the evaporation body 13 is exposed to the environment in a section of its length which is located above the opening 21 of the container 20 and thus outside the container 20, and where evaporation of the liquid containing at least one fragrance is possible.

[0033] The one in Fig. The embodiment of the room fragrance device 10 shown in the left part of the image (Figure 7) functions in principle the same way as the embodiment mentioned above, with the difference that instead of a separate stand, a bracket in the form of a hook 32 is provided on a wall of the room R, to which the upper end 14 of the evaporation body 12 is attached. The free length of this hook 32 and the positioning of the container 20 relative to the wall are arranged such that the free end of the hook 32 is located approximately above the opening 21 of the container 20. Thus, the upper end 14 of the evaporation body 12 can be attached to the hook 32 when, at the same time, the lower end 13 of the evaporation body 12 is inserted through the opening 21 into the container 20 and immersed in the liquid D.

[0034] As an alternative to a hook 32 attached to the wall of a room, a suitable bracket can also be provided on the ceiling of a room for the latter embodiment of the room fragrance device 10 according to the invention. In this case, the upper end 14 of the evaporation body 12 is attached to this bracket in order to suspend the evaporation body 12 and thereby insert the lower end 13 into the container 20.

[0035] The following is with reference to the Fig. 2a-c, Fig. 3, Fig. 4 and Fig. Figure 6 shows and explains a further embodiment of the room fragrance device 10 according to the invention, in which a supporting elongated rod-shaped element 15 is used. Details are provided below: Fig. Figure 2a shows the elongated, rod-shaped element 15 in a simplified side view. The longitudinal extent of this element 15 is shown in the Fig. 2a with “L 15 " designated.

[0036] The rod-shaped element 15 can be made of any material, for example wood, glass, stone, metal, plastic, ceramic or plaster, either, viewed in a plane perpendicular to the longitudinal axis, in a solid embodiment, or in the form of a tube which is hollow in a cross-section perpendicular to the longitudinal axis and accordingly has an interior space 16 (cf. Fig. 2c). In any case, it is important for the rod-shaped element 15 according to the invention that, thanks to the selection of a suitable material, it has sufficient stability and buckling resistance when, for example, it is placed vertically.

[0037] In adaptation to the rod-shaped element 15, i.e., with approximately the same length and diameter, the associated evaporation body 12 is selected in this embodiment of the room fragrance device 10 according to the invention. As shown in the illustration of Fig. 2b such an evaporation body 12 consists of a textile material in stocking form. Thus, such a stocking-shaped evaporation body 12 is attached to or above the rod-shaped element 15 at its outer circumferential surface A 15 (cf.) Fig. 2a) attachable.

[0038] According to the presentation of Fig. 2c is the evaporation body 12 of Fig. 2b shown in a state when it is on the outer circumferential surface A 15 of the rod-shaped element 15 is attached.

[0039] In the presentation of Fig. 2c the rod-shaped element 15 is designed in the form of a tube, which accordingly has an interior space 16. Advantageously, the rod-shaped element 15 in the form of such a tube is open at both of its end faces S1 and S2.

[0040] For the purpose of easily attaching the lower end 13 and the upper end 14 of the evaporation body 12 to the rod-shaped element 15, in the embodiment according to Fig. 2c is provided for, that a longitudinal extension L 12 of the evaporating body 12 greater than the longitudinal extent L 15 of the rod-shaped element 15, with the consequence that the end sections of the evaporation body 12, which are located at the end faces S1 and S2 (cf. Fig. 2a) protrude, then simply stuff into these open end faces S1 and S2 and then be attached to these end faces S1 and S2 of the tube 15 using respective plugs 18.

[0041] The design of the last-mentioned embodiment of the room fragrance device 10 according to the invention with regard to the rod-shaped element 15 used here in the form of the tube and the evaporation body 12, which is attached to the outer circumferential surface A 15of pipe 15 is also from the Fig. Figure 3 shows a cross-sectional view of the room fragrance device 10 along line AA of Fig. Figure 2c shows that the evaporation body 12, in the manner of a stocking, encloses the tube 15 in a plane perpendicular to its longitudinal axis L. 15 completely encloses.

[0042] Fig. Figure 4 shows the aforementioned embodiment of the room fragrance device 10 according to the invention in a longitudinal section view.

[0043] Regarding the sectional views according to Fig. 3 and Fig. 4 It should be noted separately at this point that the material of the tube 15 is shown hatched, whereby the textile material of the evaporation body 12, which is attached to the outer circumferential surface A 15 The point where pipe 15 is attached is shown with double hatching.

[0044] The above-described design of the rod-shaped element 15 in the form of a tube leads to the advantages of a relatively low weight and moderate manufacturing costs, and further advantageously also to the possibility that - provided the end faces of such a tube are open - the end sections of the evaporation body 12 can then be easily inserted into the open end faces S1 and S2 by means of suitable plugs 18 (cf. Fig. 2c) can be attached.

[0045] The representation according to Fig. Figure 4 also shows that the longitudinal extent L 12 of the evaporation body 12 to the longitudinal extent L 15The tube 15 is selected such that the evaporation element 12 completely covers the outer circumferential surface of the tube along its longitudinal extent. In this way, for the practical use of the room fragrance device 10 according to the invention, the largest possible free surface area is ensured on which the liquid D containing at least one fragrance substance can evaporate as intended in order to achieve the desired room fragrance.

[0046] The practical application of the last-mentioned embodiment of the room fragrance device 10 according to the invention is simplified in the Fig. 6 shown. This could be the embodiment according to Fig. 2c act according to which - as explained - the evaporation body 12 is attached to the outer circumferential surface A in the manner of a stocking. 15 of pipe 15 is attached. In any case, it is evident from the Fig. 6 recognizable that the evaporation body 12 (attached to the tube 15) with its lower end 13 (cf. Fig. 2b) into the opening 21 of the container 20 (see Fig. 5) is inserted so that the lower end 13 is immersed in the liquid D. As a result, the liquid D can then wet or penetrate the fibers F of the evaporation body 12, which in the Fig. 6 is symbolized by two arrows adjacent to the lower end 13 of the evaporation body 12. Subsequently, thanks to the capillary action of the fibers of the evaporation body 12, liquid D is transported through the textile material towards the upper end 14 of the evaporation body 12, which is shown in the Fig. 6 is indicated by an arrow labelled “K” within the evaporation body 12.

[0047] Finally, with regard to the last-mentioned embodiment of the room fragrance device 10 according to the invention, it should be noted that the rod-shaped element 15 used here, which – as explained – can be designed in the form of a tube, assumes a supporting function for the textile material and the evaporation body 12 formed therefrom. This is achieved by the fact that the textile material is attached to the outer circumferential surface A 15The rod-shaped element 15 or tube 15 is attached to the evaporation body 12, which can fulfill the aforementioned dual function: namely, both the transport of the liquid from the first end 13 of the evaporation body 12, which is immersed in the liquid D in the container 20, towards the opposite second end 14 of the evaporation body 12, and the evaporation of the liquid D in a section of its length that is located above the opening 21 of the container 20 and thus outside the container 20, exposed to the environment. In the illustration of Fig. 6 is this exposed length section of the evaporation body 12 with “L E " designated.
