Description

[0001] Aroma booster for a shisha

[0002] Field of the invention

[0003] The invention relates to an aroma booster for a shisha pipe—also known as a water pipe—and similar aerosol-forming devices, which enables a significant improvement in the aromatization of the aerosol (vapor or smoke). The aroma booster according to the invention comprises a hollow body with an aroma carrier and contains, for example, a connection to the hose of a shisha and a mouthpiece.

[0004] Background of the invention and prior art

[0005] Shisha smoking has become increasingly popular in Western countries in recent years. Many cities have cafes and bars that sell shisha pipes and tobacco.

[0006] The shisha is a water pipe that has been known since at least the 16th century and first spread in India and large parts of the Arab world. In many Arab countries, the shisha is an integral part of the culture; smoking it together was, and still is, viewed as a symbol of hospitality. This culture also spread to Western countries through tourists and migrants.

[0007] Structure, components and functionality of the shisha

[0008] The structure, components and function of a shisha can be described as follows. A shisha contains a water-filled vessel, the so-called bowl. A so-called smoke column with a dip tube is screwed onto this. The smoke column with dip tube is screwed onto the bowl. The bowl is filled with enough water that, once the smoke column is screwed on, the dip tube protrudes into the water. The shisha head and a charcoal carrier are placed on the upper end of the smoke column. The shisha head, together with the charcoal carrier, is also called the head structure. The shisha head is filled with shisha tobacco or the alternative carrier material described in DE102020002624A1. The charcoal carrier has one or more openings for the air flow, which basically act like a sieve. The sieve-like charcoal carrier is filled with charcoal and placed on the shisha head.

[0009] Above the water level on the bowl is an opening into which a hose with a mouthpiece can be inserted. When the mouthpiece is pulled, a vacuum is created in the bowl. This vacuum causes a flow of air that heats up over the coal and is then drawn over the tobacco or carrier material into the bowl. The glycerin flavor mixture with which the tobacco or carrier material is soaked evaporates and ultimately reaches the user's lungs via the smoke column, bowl, hose and mouthpiece. Conventional bowls have multiple openings that allow multiple hoses to be connected, so that several people can use the shisha together.

[0010] The difference between vaping and smoking in the shisha

[0011] If smoke particles, volatile hydrocarbons, or even polycyclic carbons from the combustion of falling ash are produced during heating, this is called shisha smoking. When using tobacco, the production of smoke is practically unavoidable.

[0012] If the vapor consists solely of liquid droplets, it is referred to as shisha vaping. The alternative carrier described in the aforementioned prior art allows this type of vaping without the creation of smoke particles.

[0013] In the context of the present invention, the terms "smoking" and "vaping" are used predominantly synonymously. The device according to the invention can be advantageously used in both ways.

[0014] Preparing the tobacco

[0015] For shisha, a special, very "moist" tobacco is generally used which, due to its "moisture," is difficult to ignite. Glycerin is the main humectant for hookah tobacco. Depending on the recipe, honey or various types of sugar and flavorings are usually added to this. There are hundreds of flavors that can be added, but the most popular additions to the basic flavors at the moment are menthol, mint, mint oil, and eucalyptus. Classics that are popular everywhere are Ice Grape, Double Apple, and Ice Apple. The flavorings are usually dissolved in propylene glycol.

[0016] Alternatively, a moist carrier material is used, as described in WO2021 / 220255A2. In this case, too, glycerin serves primarily as a humectant, to which flavorings are added. The same flavorings can be used as in shisha tobacco.

[0017] Depending on the amount of tobacco or carrier substance in the shisha bowl, the shisha can be smoked for approximately 30-45 minutes. Experience has shown that the aroma of the vapor / smoke typically diminishes significantly after 30 minutes, and after 60 minutes at the latest, no aroma is perceptible. Principles of the invention and preferred embodiments

[0018] The present invention is therefore based on the object of providing a novel aroma booster for aerosol-forming devices, for example a shisha, for the perfectly coordinated combination of an aroma-free aerosol and an aromatizing element, so that a perfect combination can be adjusted for each aroma and aerosol-forming carrier substance.

[0019] The aroma booster consists of an elongated hollow body, which is attached to a hookah hose, for example, so that the vapor escaping from the hookah can be channeled through the hollow body. The other end of the hollow body is shaped, for example, into a mouthpiece, through which the user can draw in the vapor. Inside the hollow body is a chamber for holding a flavor carrier.

[0020] In other embodiments of the invention, the aroma booster can also be positioned at other locations between the aerosol formation and the consumer, for example between the aerosol outlet from the bowl and the hose with mouthpiece.

[0021] In a first embodiment of the invention, the aroma carrier consists of a substantially cylindrical cotton roll. Suitable for this application are, for example, cotton rolls such as those used by dentists. These have a diameter between 0.8 and 1.2 cm and are four centimeters long.

[0022] In other embodiments of the invention, other

[0023] Materials used . These can include natural

[0024] Materials such as cellulose or cotton, modified natural materials such as cellulose acetate, or synthetic materials, preferably polymers such as elastane, PET, polyamide, polyacetate, ethylene-vinyl acetate (EVA), polyolefins, polycondensates, polyurethanes, or similar polymer materials and their mixtures are primarily used in foam-like designs. These can be produced, for example, by processes such as plastic foaming, foam extrusion, molding, MuCell processes, RRIM (Reinforced Reaction Injection Molding), PUR foams, and thermoplastic foam casting (TSG) processes. Other alternative materials include silica gel, which can absorb large amounts of liquid and has an extremely large surface area (up to 600m²). 2 / g). Mineral materials capable of absorbing liquids, such as zeolite, montmorillonite, smectite, or pumice, are also suitable. The material can also be formed as a porous or fibrous body with continuous capillaries. Within the scope of the present invention, several different materials can also be mixed.

[0025] The selected material must be capable of absorbing the aroma solution described below and effectively releasing it back to the surface of the aroma carrier. Furthermore, the material must be capable of quickly replacing aroma released at the surface through diffusion from the interior.

[0026] As already explained above, the aroma carrier can, in the simplest case, be cylindrical. Alternatively, the aroma carrier can also be designed in the form of a hollow cylinder (Figure 5 CA). Furthermore, alternatively, the cylinder can have a plurality of bores (Figure 5, CB). The aroma carrier can also be designed in the form of a prism, with a cross-section that can be polygonal (e.g. three-, four-, six- or octagonal) (see Figure 4). An aroma carrier designed in any desired shape can also have channels, depressions and / or elevations on the surface in order to enlarge the contact areas. Aroma carriers made of sponge-like polymer material (Figure 5, CG, CD, CE) can also be designed in the shapes described. Other possible shapes are disclosed in the figures.

[0027] Typically, the aroma carrier has a volume of 0.5-20 cm 3 and a surface area of ​​4-45 cm 2In many cases, the aroma carrier is cylindrical and measures 1-6 cm in length and 0.5-2 cm in diameter. In special cases, smaller or larger aroma carriers may also be used.

[0028] The aroma carriers, for example the cotton rolls mentioned above, are secured by suitable holding devices in the chamber inside the mouthpiece so that they cannot change their position and in particular cannot be sucked in accidentally. The holding devices can consist of corresponding webs which narrow the clear opening so that the aroma carrier is firmly secured in place. The holding devices can also be formed by knob-like protrusions on the inner walls of the receiving hollow body. The webs and / or knobs can influence the flow of the aerosol over the outer surface, for example by lengthening the flow paths so that the aroma exchange is intensified. The person skilled in the art can also achieve secure positioning of the aroma carrier in the central body of the aroma booster in other ways.For example, the aroma carrier can be clamped in by appropriately shaping the central body or fixed in its desired position by a spatial limitation. It is important that the aerosol flowing through the aroma booster can flow over the outer and / or inner surface of the aroma carrier, for example the cylindrical cotton roll, in order to absorb the aroma. The flow paths of the vapor or smoke over the surface of the aroma carrier (outer surface and / or inner surface) are also referred to in this description as flooding channels. The aroma booster according to the invention therefore differs significantly from similar devices from the prior art: the aerosol flowing through the aroma booster is not filtered by the aroma carrier (in particular no smoke particles are filtered out of the aerosol), but the aerosol is loaded with aroma.

[0029] The entire hollow body for holding the aroma carrier is preferably designed to be rotationally symmetrical, e.g. with a cylindrical central part and two conical attachments, one as a connection to the hose and the other as a mouthpiece. The external shape is unimportant and can also be designed in a different way. Alternatively, the aroma booster can also be shaped like a double cone. The decisive factor is the ability to hold the aroma carrier described above, for example holding at least one cotton roll 2-6 cm long (preferably 4 cm) and with a diameter of 0.5 - 2 cm (preferably 0.8 - 1.2 cm). One design option is to hold several cotton rolls (e.g. two rolls of 4 cm length one behind the other). This type of design enlarges the surface area of ​​the cylinder so that more aroma can be released per unit of time.The entire aroma booster typically has a length of 10-20 cm and a maximum outer diameter of 1.25-5 cm. When polymer foams are used as aroma carriers, the size of the aroma carrier can be reduced, as the polymer foam can absorb significantly more aroma solution per unit volume of the aroma carrier.

[0030] The entire aroma booster is preferably made of plastic, preferably by injection molding, for example, from polypropylene, polycarbonate, polystyrene, or copolymers. Other manufacturing processes, such as 3D printing, are also possible. It is preferably manufactured in two parts, which are then assembled using locking elements to form the finished aroma booster. This allows the aroma carrier, e.g., in the form of a cotton roll, to be inserted before the two halves are joined.

[0031] The aroma carrier is soaked with an aroma solution for use in the shisha. The aroma carriers are able to absorb large quantities of solution. Care must be taken to ensure that so much solution is not absorbed that it flows out after being inserted into the aroma booster chamber. A cotton roll weighing approximately 0.5g, 3.8cm long, and 1.2cm in diameter is able to absorb 3-5ml of solution. Cotton rolls with other lengths and diameters absorb less liquid due to the change in volume. When using aroma carriers made of polymer foam, a cylinder 1.5-2cm long with the same diameter is sufficient to absorb 1.5-3ml of solution.

[0032] The solvent content in the flavoring solution preferably, but not exclusively, consists of 1-30% propylene glycol and 70-99% of the flavoring substances (raw material content). Small amounts of ethanol (or other physiologically acceptable solvents, e.g., water, glycerin) may be included if necessary. The flavors (e.g., apple, pear, strawberry, vanilla, coconut, blueberry, blackberry, orange, lemon, bergamot, melon, pineapple, cinnamon) are commercially available and therefore require no further explanation here. To achieve a weaker flavoring, the solvent content can also be 31-99% and the flavoring raw material content 1-69%.

[0033] The manufacturer Hertz & Selek offers, for example, an ice candy flavor:

[0034] The solvent content of this flavor is 18% in the form of propylene glycol.

[0035] The flavoring raw material concentration would be 82%. (Flavoring raw material concentrations are usually raw material mixtures that then produce the desired flavor.)

[0036] According to the invention, it is possible to insert the soaked aroma carrier into one half of the aroma booster and then seal it with the other half. Alternatively, it is possible to insert the dry aroma carrier into one half of the aroma booster, seal the aroma booster with the other half, and then inject the aroma solution into the cotton wool using a syringe. For manufacturing reasons, the first variant is preferred.

[0037] The finished aroma booster, loaded with aroma solution, can be sealed in a packaging film and stored in this form for at least 12 months. It is advantageous to seal the aroma booster with two end caps before sealing, which prevents premature loss of aroma.

[0038] The holding elements described above hold the cotton roll in such a way that the vapor or smoke from the shisha is guided over the outer and / or inner surface (e.g. in the case of hollow cylinders) when sucking on the mouthpiece. The flowing aerosol absorbs the aromas contained in the cotton.

[0039] The aroma booster according to the invention, in one embodiment as described above, is plugged onto the hose of a hookah. For this purpose, it is conically shaped on this side. Typically, plugging it into the hose opening creates a sufficient seal. The cone of the aroma booster can, of course, also contain sealing elements, such as rubber rings, to improve the seal with the hose. At the other end, the aroma booster also contains a substantially conical shape, similar to the mouthpieces used in a hookah. The aroma booster according to the invention can also be plugged onto a conventional mouthpiece of a hookah (similar to the well-known “hygienic mouthpieces”). The connection elements of the aroma booster can also have a screw connection, a bayonet connection, or a magnetic closure. In any case, additional sealing elements (e.g.Rubber rings) may be present to further improve the tightness of the connection.

[0040] In other embodiments of the invention, the aroma booster is positioned at a different location between the aerosol generating element (typically but not exclusively the shisha head) and the mouthpiece, for example between the aerosol outlet on the bowl and the hose (see also Figure 14).

[0041] The aroma booster according to the invention allows various ways to improve shisha smoking or vaping.

[0042] Firstly, the aroma booster can enhance the aroma experience. For this purpose, the aroma contained in the aroma booster can be identical to the aroma present in the shisha bowl. The result is an intensification of the aroma experience (aroma booster). This not only makes the taste significantly more intense: the shisha user also experiences a much more differentiated taste. For example, it is possible to differentiate between different types of mint using the aroma booster according to the invention, whereas with conventional shisha smoking, different types of mint in the shisha bowl do not lead to a different taste experience for the user.

[0043] It is also possible to operate the shisha bowl entirely without flavoring. To do this, simply heat commercially available shisha tobacco and / or a tobacco-free carrier in the shisha bowl. This way, the flavoring is not added to the bowl, but rather via the flavor booster, ensuring the more intense and differentiated flavor experience described above. Aerosol generation can also be achieved purely by electrically heating glycerin and / or propylene glycol, for example, similar to a vape.

[0044] The aroma booster according to the invention also makes it possible for several people to enjoy different flavors at one hookah by using differently flavored aroma boosters. This eliminates the need to agree on a flavor before using a hookah. Each person can obtain their preferred flavor from the respective aroma booster.

[0045] It is also possible to use a first flavor in the shisha bowl and a second flavor in the aroma booster. This allows for individually selectable flavor combinations that go beyond the usual commercial offerings.

[0046] It is also possible to use two aroma boosters in combination. For example, there are fans of mint aromas who like to combine other aromas with mint. By connecting two aroma boosters, it is possible, for example, to combine a first aroma (e.g., apple aroma) with a second aroma (e.g., mint aroma). It goes without saying that any other aromas can also be combined in this way.

[0047] What all applications have in common is that the flavoring effect of the aroma booster according to the invention lasts for a very long time without losing any intensity. With conventional shisha smoking, the smoke or vapor typically loses its flavor intensity after a few minutes; after 60 minutes at the latest, no aroma is perceptible anymore. However, the aroma booster according to the invention can generally be used for more than four hours without losing any flavor intensity. In some cases, the aroma booster according to the invention could be used for 6-10 hours.

[0048] It was initially surprising to those skilled in the art that a significant aromatization of the smoke or vapor was possible with the aroma booster according to the invention. The expert opinion was that the aromas in the shisha bowl had to be heated in order to evaporate the aromatic substances. A comparatively cool aerosol (between 20°C and 40°C) flows through the mouthpiece according to the invention because the aerosol in the bowl was cooled accordingly as it flowed through. It was not to be expected that sufficient aromatization of the aerosol would be possible at this temperature.

[0049] Furthermore, it was surprising to the expert that a significantly more differentiated aroma perception was possible with the aroma booster according to the invention compared to conventional shisha smoking. Without wishing to be bound by this theory, it is suspected that the conditions usually prevailing in the bowl of the shisha (temperature between 300 and 800°C) can lead to a (partial) degradation of the very sensitive aroma substances, so that taste nuances are lost. In addition, the aroma substances in the bowl are washed out (particularly the hydrophilic aroma substances) and the vapor / smoke has to travel a comparatively long distance through the smoke column (typically approx. 50 cm) and the hose (typically approx. 100 cm), so that in the end only a small part of the originally used aromas reaches the user.

[0050] The device according to the invention is further illustrated by the accompanying figures. The figures show various embodiments of the invention without intending to be limiting. Those skilled in the art can readily construct variants and other embodiments of the invention without requiring inventive activity.

[0051] Figure 1 (Figure X) shows a basic configuration according to the invention.

[0052] In sub-figure XA, 1.1, the smoke tip, is the upper part of the mouthpiece. An opening 1.3 is provided on the top, onto which a closure cap 3.1 can be placed. 1.2 is the hose connection, the lower part of the mouthpiece, with an opening 1.4 on the bottom, which can also be closed with a closure element 3.2.

[0053] Partial Figure XB depicts an aroma carrier (2) that can hold liquid, e.g., aroma solution 4, and release it as an aerosol and / or liquid. 4 shows an aroma liquid that fills the aroma carrier 2.

[0054] The assembled aroma booster is shown in partial figure XC. The aroma carrier 2 has been placed inside the aroma booster. The smoke tip 1.1 of the aroma booster has been closed with the hose connection 1.2 of the aroma booster. Thus, the filled aroma carrier 2 with the filled aroma 4 is located inside the interior. On the underside, the aerosol can flow through the opening through the flooding channel of the aroma booster towards the top opening, where the aerosol flows past the aroma-filled 4 aroma carrier 2 and absorbs the aroma 4. Here, the aerosol mixes with the aroma to form the flavored aerosol 2 / 4. The bottom opening 1.4 can be closed with the closure element.

[0055] 3.2 and the upper opening 1.3 are closed with the closure element 3.1. Furthermore, in Figure XC, the components 1.1 and 1.2 and their designed openings

[0056] 1.3 and 1.4 offer another advantage. The narrower part (1.4) fits snugly into the opening (1.3). This makes it possible to nest two aroma boosters and allow the airflow through both nested aroma boosters to flow past the respective aroma carriers. This makes it possible to mix two or more aromas together. The aroma boosters can also be attached using screws, bayonets, magnets, or similar locking devices.

[0057] Figure 2 (Figure A) shows embodiments of the aroma carrier 2.

[0058] In Figure AC, 3 denotes the assembled aroma booster with an inserted, round, roll-like aroma carrier A4. This is the standard version, in which aroma carrier 2 is used, which aromatizes the aerosol via the outer surface.

[0059] Furthermore, the material and the material structure of the aroma carrier 2 can be designed in such a way that even in the soaked state, many small flooding channels are present, which together offer a large surface and thus release area of ​​the aroma.

[0060] In another example, where a slightly smaller / narrower aroma carrier tilts inside and thus leans slightly to one side towards the inside of the aroma booster, the flooding channel is reduced in size on one side but enlarged on the other.

[0061] In partial figure AE, the aroma carrier 6 is a preferably, but not exclusively, wave-shaped outer surface 6.1. It is important here that through a deliberate, but arbitrary formation of the structure in the outer surface and / or at another, arbitrary location of the aroma carrier 6, the aroma carrier 2 serves as a contact surface for the aerosol and for aroma absorption.

[0062] This special structure is designed to create a larger contact surface. Furthermore, this aroma carrier 6 could be inserted so that it fits flush with the inner walls of the aroma booster 3, while still providing flooding channels for the aerosol to pass through due to the wave-shaped structure of the aroma carrier 6.1. The surface area can also be increased, for example, via a hollow element or an internal channel.

[0063] In partial illustration AD, a hollow element 5.1 is used under 5 and 5.1 as the aroma carrier 5. This can be inserted so that it fits snugly against the inner walls of the aroma booster 3, so that the aerosol stream can only flood through the hollow element. Or a minimal space can be created for the outer surface of the aroma carrier. The aerosol thus floods through the hollow element / channel, the inner channel, and also along the outer surface of the carrier element. The hollow element guarantees that the flooding channel of the aroma booster does not become blocked, since the flooding channel of the hollow element 5.1 is inserted centrally in the interior. This means that displacement is not possible. Even in the variant with minimal space for the outer surface of the aroma carrier 5, the aerosol channel 5.1 of the aroma carrier 5 will only be able to slip minimally. This can occur during production of the carrier 5 / 5. 1 taking this into account in the size of the aerosol channel 5 .1 must be taken into account, so that flow through the aroma booster as well as through the aroma carrier 5 and the aerosol channel 5 . 1 is always guaranteed, even with the smallest possible slippage.

[0064] Partial illustration AA shows the aroma carriers AA1 and AA2, preferably but not exclusively made of different materials. Carrier AA1 represents / provides the aroma tank. The material and structure of an aroma carrier AA1 is designed so that it can absorb and release a lot of liquid. The material and part AA2 is a hollow element which is pulled over the outer surface of the aroma carrier. The element AA2 is made of a material which draws liquid through the concentration gradient into the entire part AA2 through many channels, similar / comparable to chromatography. The material used can preferably but not exclusively be a silica-like product, nylon or similar. Their surface structure is further enlarged by a special shaping (similar to part illustration AE).The advantage here is that a large dispensing area is offered, but the tank itself in the aroma carrier AA1 remains small and is not wasteful of liquids / aromas. Due to the special physical and chemical properties and / or a material and / or structural composition that creates many capillaries, which draw the liquid / aroma from the carrier tank AA1 into the entire carrier part AA2, until carrier part AA2 is saturated. When the aromas are dispensed through carrier part AA2, liquid / aroma is drawn from carrier tank AA1 into the carrier part AA2.

[0065] Partial image AB shows AB2 . 1 and ABI . 1 a similar function to that shown in AA2 and AA1 , the material structures are similar / identical to that in partial image AA and their function . In ABI . 1 is the tank and in AB2 . 1 there is an enlarged surface, but here the only difference is that AB2 . 1 , here the hollow element AB2 . 1 is inserted into the aroma carrier ABI . 1 with the aroma in the inner channel ABI . 1 of the hollow element.

[0066] Figure 3 shows the images Al .

[0067] The system is reflected here as described in Figure A under sub-figure AA. The difference is that the aroma carrier Al-1 has now been pushed into the middle of the hollow body Al-2. This combination A1A can then be inserted into the interior of the aroma booster 3. The advantage here is that an improvement in the flooding channels is guaranteed because A1A cannot block the top and bottom / at the taper because the part Al-2 sits on the air openings of the aroma booster 3 like a top and bottom pipe socket. The aroma carrier, which is inserted, could have many small flooding channels due to its material structure. Or it could also have hollow flooding channels in the inner area of ​​the carrier Al-1 (similar to part AID under Al-5.1). Or also by the shape / preferably but not exclusively wave-shaped on the outside / outer surface of the carrier Al- 1 / similar to that in partial figure AE .This creates flooding channels in design A1B and an enlarged surface on the top and bottom due to the external hollow element.

[0068] Partial Figure AC shows the hollow element / aroma carrier AC5 with an internal flooding channel AC5.1. This aroma carrier AC5 is inserted into the interior of the aroma booster 3, preferably but not exclusively, fitting with the outer walls of the aroma booster 3 and thus without a flooding channel on the outer surfaces of the aroma carrier AC5, since this fits tightly with the inside of the aroma booster 3 in the interior.

[0069] In this version, a hollow element AC5, AC5.1 was created, with an internal flooding channel AC5.1, which with its upper and lower sides AC5.1 on the openings of the aroma booster 3 and thus creates a permeable flooding channel.

[0070] Figure 4 shows images B.

[0071] Figures B show new, different shapes for the aroma carriers B1, B2, B3, B4, in relation to an outer surface to be offered by the aroma carrier B1, B2, B3, B4 and with the aim of not closing off the tapered flooding channels of the aroma booster 3. Thus, preferably but not exclusively, a shape is selected in the outer surface of the aroma carrier so that the top and bottom flooding channels are not covered and the aerosol can pass along the outside of the aroma carrier. The corners due to the shape of the novel aroma carriers B1, B2, B3, B4 can also have a fixing effect in the interior of the aroma booster 3, but without completely covering the flooding channel of the aroma booster 3. Figure 5 shows figures C.

[0072] In partial figure CA, a hollow element is designed as aroma carrier Cl . 1 with a single internal channel .

[0073] In order to guarantee more contact surface, in the partial illustration CB the aroma carrier CB2 is provided with at least two flooding channels, in this version with three flooding channels.

[0074] . 2 / CE3 . 2 , which in turn do not stick together due to the firm structuring based on the material selection even when the aroma carrier 3 is fully soaked, and the flooding channels CC3 . 2 / CE3 . 22 are retained. The large number of flooding channels CC3 . 2 / CE3 . 2 created in the partial figures CC and CE result in a very large surface area, comparable to that of a complete outer and / or inner surface known from the figures and partial figures described above. Figure 6 shows the figures CI .

[0075] In partial illustration C1A, an aroma carrier C1A1 can be seen which, through certain shapes such as channels and / or feet C1A2 on the top and bottom, creates various air-permeable flooding channels C1A2, even when the carrier element C1A1 is standing on the top and bottom openings of the aroma booster. Here, a certain amount of space was deliberately created on the outside between the aroma carrier C1A1 and the inside of the aroma booster 3 by making the said aroma carrier C1A1 slightly smaller in diameter than the inside of the aroma booster 3 in the interior. In this way, flooding over the entire aroma carrier is ensured by the flood-actively designed top and bottom sides C1A2 of the aroma carrier C1A1 and by the minimal space created between the aroma booster 3 and the aroma carrier C1A1.

[0076] In partial illustration C1B the same result is shown but with a much larger outer surface. Here an aroma carrier C1B3 can be seen. In the partial illustration marked C1B4 deep flooding channels directed towards the center have been created. This allows the aerosol to flow through the upper and lower openings of the aroma booster 3 through the created flooding channels, which in turn flow past the enlarged outer surface shape and absorb the aroma. The depth of the flooding channels C1B4 towards the center of the aroma carrier C1B3 reduces the radius in the center of the carrier element at least far enough that the radius at least at the deepest point of the flooding channel C1B4 is smaller than the radius of the upper and lower flooding channels of the aroma booster 3 in the interior. Figure 7 shows the illustrations D.

[0077] Figures D show the various options for creating the flooding channels and / or retaining elements in the aroma booster 3, as described above. These are intended to ensure the best possible aroma exchange and air flooding in combination with the aroma booster 3 and the aroma carrier.

[0078] In sub-figure DA, an integrated air channel is created under DAI. 2, which is formed by a recess in the material of the aroma booster. The devices under DAI. 1 are possible holding elements for the aroma carrier.

[0079] Further designs for the aroma carrier are described in partial figure DB. These are as follows: an external shape DB2.1, an internal shape DB2.2, and the material structure with the creation of flooding channels DB2.3, which are minimal in size but offer a large surface area due to the multitude and summation of all flooding channels and, thanks to the material selection (preferably mixed material), retain their given produced shape / structure even when fully impregnated.

[0080] Figure 8 shows the images E .

[0081] Partial illustration EA shows an aroma booster 3 which has flooding channels on the underside, but also possibly on the top, in the interior of the aroma booster. These flooding channels are incorporated into the material in the form of depressions. This could be achieved by shaping the pointed foot, but also through material, recesses, etc. Another production option would be a two-component workpiece if the material thickness is not sufficient for recesses. Thus, as can be seen in partial illustration EB, a first material could be produced with the recesses EB1 and then the second material EB2 would be produced around the outside of the first material after the two-component production.

[0082] This version of the Aromabooster 3 creates or enables various flooding channels even with a precisely fitting aroma carrier roll

[0083] By adapting the flooding channels to the tapered openings on the top and bottom, a complete air flow without blockage is guaranteed

[0084] In partial illustration EC, a precisely fitting aroma carrier EC4 is again shown on the underside, which, with its internal flooding channel / , centrally terminates at the top and bottom of the openings of the aroma booster 3. A top view is shown in EC4.1. To create an enlargement of this contact surface in the inner channel, the shape of the inner flooding channel in partial illustrations EE and EF was enlarged, preferably but not exclusively by means of a wave shape.

[0085] A preferred design in this case is to use the combination of the aroma carrier EE / EF in the partial image EA shown above with the incorporated flooding channels on the inner wall of the aroma booster 3. This would create an extremely large contact surface in the sum of the surfaces. Figure 9 shows the images F.

[0086] The importance for the aroma carrier in relation to the combination of the contact surfaces to be created and / or the material selection and / or the material structuring created during production for the best possible aroma exchange or continuous, constant quantity release is now explained.

[0087] It is important to choose a material that allows the aroma liquid to flow quickly to the contact surface (contact surface with the aerosol). This is the only way to replenish the aroma liquid that has already been carried away by the aerosol at the contact surface. For this, the selection of the material and / or the selection of the material structure is important in order to create an optimal infrastructure of flow channels, capillaries, etc. in the aroma carrier in order to allow liquid to flow from the space to the "empty" space, the contact surface. This happens through the osmotic gradient in order to restore osmotic equilibrium. In this way, the contact surface that is responsible for the exchange or release of the aroma to the aerosol is always constantly supplied with aroma liquid.

[0088] The partial image FA shows an internal flooding channel FA3. Here, the aroma liquid flows into the center of the aroma carrier FA1 to the "emptied" contact surface FA2.

[0089] In partial figure FB, the contact surface for aroma exchange is on the outside of the aroma carrier FB5. Here, the internal liquid is drawn outwards by osmosis in order to refill the contact surface with liquid. The functioning of the osmotic equilibrium works in the same way as in partial figure FA, except that the contact surface, which releases the aroma liquid, is on the outside and therefore the liquid flows outwards to the outer wall of the aroma carrier due to the osmotic gradient. There, the aerosol FB4 can then repeatedly absorb aroma from the outer surface of the aroma carrier FB5.

[0090] Figure 10 shows the images G .

[0091] Partial Figure GA again shows the Aromabooster 3 with its upper and lower sections and the resulting interior. Partial Figure GC shows a roll-shaped aroma carrier, which is then inserted into an adapter device GB. The adapter GC2 has, like the version described in partial figures E / partial figures EA / EB, flooding channels on its inner wall. This ensures flooding and the flow of the aerosol when the aroma carrier GC1 is inserted into the adapter GC2 and this is then inserted into the Aromabooster 3.

[0092] Figure 11 shows the images H .

[0093] The Aroma Booster 3 is shown in partial illustration HA. Here, a different type of adapter is shown in partial illustration HB. Openings HB4.1 are located on the top and bottom, which allow air to pass through the inserted aroma carrier / cotton roll. The aroma carrier HB1 is inserted into the adapter, and the adapter HB4 into the Aroma Booster 3.

[0094] In partial illustration HD, the adapter HD4 could have a protruding pipe socket HD4 on the top and bottom in addition to the openings. 2 to prevent clogging of the top and bottom openings in the aroma booster 3 and the adapter HD4. Figure 12 shows illustrations I.

[0095] In Figure 1A, spheres II of the same size (II.1) are shown as a possible design for the aroma booster 3. Because these spheres are always the same size, the resulting free space and air channel can be calculated.

[0096] The same applies to the partial images IC and ID with tube-like elongated elements IC2) of always the same size to create a flooding channel to be calculated.

[0097] 12.1

[0098] Figure 12.1 shows the central body (2,3), in which the inner walls consist of several separate inner wall segments (1, 1.3) which are arranged in such a way that a vortex-generating funnel shape as well as an extension and rotation of the aerosol stream (1.4) occurs.

[0099] Similar to a fan, the passing air / aerosol / vapour / smoke is forced / forced (1.1) through the diagonally connected inner walls into a rotating air stream (1.4)

[0100] This rotating swirling of the airflow could also be achieved by diagonally arranged or wave-shaped fins inside the central body, which could preferably, but not exclusively, also function as holding elements.

[0101] Figure, 13

[0102] Figure 13 shows the central body (3) being inserted into the end of the shisha hose (2). Here, the lower part of the central body, together with the plug-in device (3.1), is produced with a surface that is preferably more resistant to insertion. This could be another material, a rubber coating such as silicone, TPE, or similar. However, this is not preferred exclusively in a production process for two components. The softer surface ensures a more secure attachment when inserting the central body, and also prevents airflow through the outer walls, channeling the airflow completely through the interior of the central body.

[0103] Figure, 14

[0104] In Figure 14, the central body is positioned at the lower end of the hose, directly attached to the shisha / water pipe. Thus, it acts as a middle piece between the shisha water pipe and the hose.

[0105] Figure 15 schematically shows an application of the aroma booster according to the invention with aromatization function for a hookah. The aroma booster itself is designated by the reference symbol XI. It contains an aroma carrier X2 inside the rotationally symmetrical central body. Figure 15 shows three different embodiments of such aroma carriers. These are provided with the aroma before use.

[0106] (F6). Also explained under X4 is the structure of the aroma booster, which consists of two halves, so that the aroma carrier can be inserted into the interior of the aroma booster and then closed.

[0107] When using the aroma booster according to the invention, it is pushed onto the hose of a hookah through one of its conical ends. In this way, the aerosol formed in the hookah head is directed into the aroma booster after passing through the water bath in the bowl when the consumer sucks on the aroma booster. The formation of aerosol in the hookah requires that an aerosol-forming substance in the hookah head is heated to a sufficient temperature for an aerosol to form. For this purpose, for example, tobacco leaves or a tobacco-free carrier material (e.g. made of cellulose) or a mixture thereof is used, which is moistened with a solution of (e.g. glycerin, propylene glycol and water). The main component of this solution is usually glycerin. The solution can also contain flavorings. In contrast to the classic hookah, no flavoring is required in the hookah head for the use of the aroma booster according to the invention.In the classic shisha, the temperature is adjusted via the type, size and number of coal pieces or the distance between the coal and tobacco and / or by regulating the ventilation and / or by covering the coal and / or tobacco. This adjustment is usually made manually according to feel. Alternatively, an electric heater can be used, which typically allows a more precise adjustment of the temperature. The temperature in the shisha head can, depending on the exact design and the airflow, be between 300 and 850 °C in the coal, while in the tobacco or carrier material it can reach around 150-300 °C.

[0108] Aerosol formation from a mixture of glycerin, propylene glycol, and water begins at considerably lower temperatures. At temperatures above 200 degrees Celsius, even sensitive aromas can be decomposed.

[0109] The aerosol formed in the shisha head is passed through the bowl and through the aroma booster by suction on the mouthpiece of the aroma booster according to the invention. In the aroma booster, the aerosol flows over the aroma carrier and thereby absorbs the aroma. The temperatures in the aroma booster are between room and body temperature. It was surprising to the expert that at this temperature the aerosol absorbs sufficient aroma to be subsequently perceived by the user. The flow of the aerosol requires an air channel. Depending on the precise design, this air channel can, for example, be formed between the outer surface of a cylinder and the inner surface of the aroma booster. Appropriate webs or knobs can be used here to fix the aroma carrier in such a way that sufficient air flow can occur around it.The air channel can also be formed so that it lies inside the aroma carrier, for example, by using a hollow cylinder. Alternatively, the aroma carrier can have a star-shaped cross-section, so that when inserted into the aroma booster, channels are formed on the surface, which ultimately increase the total surface area of ​​the aroma carrier.

[0110] Due to the comparatively low temperature within the aroma booster, there is no risk of thermal decomposition of the aroma substances.

[0111] Figure 16 shows again the conditions in the aroma booster 2 according to the invention. The glycerol vapor X3 passes through the conical connection piece of the aroma booster indicated below into the interior of the aroma booster X2. In this example, the flow takes place around the cylindrical aroma carrier (direction of the arrow). For this purpose, a distance is required between the aroma carrier and the inner wall of the aroma booster, which can be formed, for example, by corresponding webs and / or knobs. The flow path can also be changed by shaping the webs. These can, for example, be arranged parallel to the aroma carrier, in a wave-like or spiral shape, so that different flow path lengths are conceivable. Less intense aromas can be enriched in the aerosol by extending the flow path. The flavored aerosol can then be sucked in through the mouthpiece R.The design of the device according to the invention allows for a high level of variability, which can be adapted for different flavors. The Aerosol X3 is preferably unflavored for the application according to the invention, but can also already contain flavors. The design of the aroma booster allows for a high level of variability, allowing the use of different flavors. It goes without saying that the concentration of the aroma solution can vary, as can the amount of aroma solution that can be absorbed by the carrier. It is not a given that the surface of the aroma carrier can also be varied, e.g. by using different materials and / or different shapes. The carrier material itself can also be varied. Finally, the length of the flow path can also be influenced. In this way, the taste perceived by the user can be individually adjusted.

[0112] Figure 17 shows schematically the various chemical and / or physical properties of the components of the invention when used according to the invention. The various chemical and / or physical properties and their interactions with one another determine the result. The individual components and their properties can be selected and coordinated with one another as required in order to influence the result. The reference symbol XI here designates a standard shisha which emits a standard aerosol. As already explained above, the aerosol is formed by applying a solution containing glycerol, propylene glycol and water to a carrier material and heating it. Shisha tobacco, but also tobacco-free material, e.g. cellulose, can be used as the carrier material. Mixtures are also possible. The aroma booster according to the invention contains in particular the aroma carrier (carrier element).This can be made of different materials and contained in varying amounts. The material and its quantity determine the absorption properties for the aroma.

[0113] Of course, the aroma concentration can vary. The release of the aroma into the flowing aerosol is influenced by the material and its surface. Upon contact of the aerosol with the aroma on the surface of the aroma carrier, the aroma transfer occurs depending on the contact time, the aerosol concentration, the aroma concentration, the size of the air channel, the release capacity of the aroma carrier, the aerosol absorption capacity, the contact time and the contact area, as well as the osmotic gradient. All of these different properties can be varied to achieve an optimal result for the use according to the invention.

[0114] Figure 18

[0115] In Figure 18, the central body (one) is shown in two parts. In 1.1, the support element is inserted.

[0116] In Figure 18.1, under three and two, the support element is written, which is inserted into the central body.

[0117] What is new here is that preferably, but not exclusively, the carrier element and the aroma liquid are stored separately by attaching a liquid container (three) with an injection opening (3.1) to the top of the carrier element (two). The injection opening (3.1) points into the carrier element attached underneath. The aroma liquid is thus sealed and isolated, but can be filled into the aroma carrier / carrier element using a manual process / step (18.1 to 18.2). This is done in a closed system, without opening the central body. This is done by assembling the central body (18.1) in a sealed manner, but in a first position. A second position can be reached by pushing the upper part of the central body together lengthwise downwards over the internal pipe socket (1.1) attached to the lower part of the central body.Thus, the previously larger interior space of the central body (18.1) is reduced to a smaller interior space (18.2) and thus causes the liquid from the liquid chamber (3) arranged on the top to be filled into the carrier element / aroma carrier (18.2) via the liquid injection opening (3.1).

[0118] A safety device on the middle part / pipe socket (1.1) to guarantee a secure position between position 18.1 and 18.2 could be a plastic ring, preferably but not exclusively used, which is clicked in and removed when necessary to fill the carrier element with liquid.

[0119] Figure 19

[0120] Figure 19 describes a further device with a new function for attaching an aroma liquid container to the carrier element / aroma carrier and subsequent mixing / filling

[0121] In Figure 19, the upper and lower parts of the central body (one) are shown, with fin elements (1.1) attached to the inside of both central body halves

[0122] In 19.1, a carrier element / aroma carrier (2) with an internal hollow element / internal channel (2.1) is shown.

[0123] An aroma liquid container (3) is inserted into this hollow element. Due to its special shape, it fits tightly into the internal aroma carrier channel (2.1) with an elongated aroma liquid container (3.2). The aroma liquid container also has a stopper element that secures the liquid container after it has been inserted into the aroma carrier and prevents it from slipping into the channel.

[0124] The inserted liquid container (3.2) is slightly longer than the aroma carrier / carrier element (2). Thus, the end piece of the liquid container (3.2) protrudes from the lower end of the aroma carrier. Another identical stopper (3.1) is attached here, preventing the aroma liquid container (3) from sliding up and down.

[0125] The now finished aroma carrier with aroma liquid container (19.2) is now inserted into the device of the central body 19

[0126] In 19.3, the opening of the liquid container (3) is described by axially twisting the upper and lower halves of the central body (1). Here, the inner fins, elements (1.1) of the central body, engage the upper stop elements attached to the bottom of the liquid container (3.1).

[0127] The liquid container is opened by the mutual axial twisting movement of the upper and lower central body halves, preferably but not exclusively through a material break or an opening. This releases the liquid from the aroma liquid container to the aroma carrier / carrier element. This, too, takes place within a closed system. Figure 19.1

[0128] Figures 19.4 and 19.5 describe a further device having an aroma carrier / carrier element with an attached liquid container. Here, in a preferred but not exclusive device, the liquid container from Figures 19 / 19.2 is mounted in the interior of the central body. At least one actuating element (five) is provided in at least part of the central body, preferably but not exclusively mounted centrally, which can be moved from a position 19.4 / 5 to a position 19.5 / 5.1. Position 19.4 is a position in the state without manual intervention. In Figure 19.5, at least one actuating element (five) is manually pushed in towards the interior, thus causing the liquid container (19.2) to create an opening element and release the aroma liquid to the carrier element / aroma carrier.

[0129] Figure 20

[0130] Figure 20 shows various devices, which describe a preferably, but not exclusively, attached center piece, which is placed between the two halves (top and bottom). This center piece (3) serves as a holder for securing the aroma carrier element (2), designed in such a way that the holder is configured to allow unrestricted airflow (3.0) through the central body, but the aroma carrier is held in position.

[0131] In Figure 20, the intermediate part is described as a loose, insertable functional part. This fits between the upper and lower parts of the central body.

[0132] Figure 20 shows, in particular, another possible device for insertion into the central body. This depicts a tube-like centerpiece, which has the functional part firmly formed in the center of the tube.

[0133] Thus, the middle piece 3.2 is inserted into the interior of the central body between the upper and lower parts. The advantage here would be a possibly better fixation due to the shape of the functional part 3.2.

[0134] A similar tubular functional part is shown as 3.3, with the bracket at the lower end being a solid part. Plastic injection molding is preferred, but not exclusively!

[0135] Figure 3.4 shows the centerpiece for all functional parts with an additional opening for airflow. Here, airflow is not only possible through the open areas outside the cross (3.0), but the centerpiece is also manufactured so that the central bracket also provides airflow, as shown in 3.4. This device is preferred for the device shown in Figure 8 / Figure 2 / AD, Figure 3 / A1D, and Figure 5CA.

[0136] A particularly simple embodiment of the invention is shown in Figures 21-22.

[0137] Figure 21 (above) shows the external view of the aroma booster according to the invention.

[0138] Figure 21 (below) shows a cross-section through the aroma booster according to the invention.

[0139] Figure 22 (top) shows one half of the aroma booster according to the invention (mouthpiece attachment) with the chamber for accommodating a cotton roll. Figure 22 (bottom) shows the complementary second half of the aroma booster according to the invention (tube attachment) with the chamber for accommodating a cotton roll.

[0140] The reference symbols used in Figures 21-22 have the following meaning:

[0141] 1) Hose connection of the aroma booster

[0142] 2) Mouthpiece of the aroma booster

[0143] 3) Central body with holder for cotton roll

[0144] 4) Chamber with cotton roll

[0145] 5) Bridge for centering the cotton roll and ensuring steam flow over the surface of the cotton cylinder

[0146] 6) Spacer to ensure gas flow to the mouthpiece

[0147] 7) Plug connection with sealing elements (inner part)

[0148] 8) Plug connection with sealing elements (outer part)

[0149] The embodiment of the invention shown in Figures 21-22 can be used as follows:

[0150] Example 1:

[0151] A cotton roll with a length of 4 cm and a diameter of 2 cm is used as an aroma carrier (surface: 31.4 cm 2 , Volume: 12.56cm 3). The aroma carrier is soaked with 3ml of a flavor solution containing 75% propylene glycol and 25% of a flavor solution (containing apple and mint flavor). After assembling the aroma booster, one connector is put onto the hose of a hookah. The other connection element forms the mouthpiece. The hookah is operated in a known manner, with the heat source being formed by pieces of coal that heat a tobacco-free carrier (according to WO 2021 / 220255 A2) that is soaked in glycerin / propylene glycol. Heating the soaked carrier creates an aerosol that can be sucked in by sucking on the mouthpiece of the aroma booster. The aerosol passes through the water bath in the bowl and enters the aroma booster, where it is flavored. The aroma booster can be operated for more than four hours without the aroma taste diminishing.

[0152] Example 2:

[0153] A cotton roll with a length of 4 cm and a diameter of 2 cm is used as an aroma carrier (surface: 31.4 cm 2 , Volume: 12.56cm 3). The aroma carrier is soaked with 3ml of an aroma solution containing ice candy aroma (82% aroma, 18% propylene glycol). After assembling the aroma booster, one connector is attached to the hose of a shisha. The other connecting element forms the mouthpiece. The shisha is operated in a conventional manner, whereby the heat source is formed by pieces of coal that heat a tobacco-free carrier material that is soaked in glycerin / propylene glycol. By heating the soaked carrier material, an aerosol is developed, which can be sucked in by sucking on the mouthpiece of the aroma booster. The aerosol passes through the water bath in the bowl and reaches the aroma booster, where it is flavored. The aroma booster can be operated for more than four hours without the aroma taste diminishing. The aroma is perceived by consumers as more intense than the aroma in example 1. To weaken the perceived aroma, there are, among other things,The following customization options are available:

[0154] - Reducing aerosol production in the shisha head by lowering the temperature in the shisha head (Example 2.1)

[0155] - Dilution of the aroma solution (Example 2.2) - Reduction of the surface area by geometrically changing the aroma carrier (e.g. reducing the diameter of the cotton roll (2 cm) or using a cotton ball instead of a cotton roll) (Example 2.3)

[0156] Example 3:

[0157] The aroma booster used in Example 1 can also be used with a conventional hookah that produces aerosol based on glycerin-containing tobacco. In this case, too, it can be used for several hours.

[0158] Example 4 :

[0159] The aroma booster used in Example 1 can also be used with a hookah containing one of the aerosol-forming substances according to German Utility Model 20 2019 103 342.8. Similarly, it can be used for several hours.

[0160] Example 5:

[0161] The aroma booster used in example 1 can also be used with a smaller cotton roll (e.g. 2cm length, 2cm diameter, (surface: 18.9cm 2 , Volume: 6.28cm 3 ) can be used with a tobacco-free shisha. In this case, only 1.5 ml of flavoring solution is used. The usage time is shorter, but still more than 1 hour. The flavor intensity is lower than in Example 1, because the surface area of ​​the flavor carrier is smaller and thus releases less flavor per unit of time.

[0162] If the aromatization is too weak for the user, the following adjustment options are available:

[0163] - Increasing the concentration of the aroma substances in the solution (Ex. 5.1) - Increasing the surface of the cotton roll, e.g. by

[0164] Raises and depressions on the cotton roll or

[0165] Use of rollers with a star-shaped cross-section (e.g.

[0166] 5.2)

[0167] This patent application claims the priorities of the German utility models DE 20 2023 000531.0 (filing date: 6 March 2023) and DE 20 2023 001 893.5 (filing date: 6 September 2023), the complete contents of which are hereby incorporated by reference.
