Description

Technical Field

[0001] The present invention relates to a water pipe, which has a shell in which a receiver and a heating chamber are combined. The receiver is to be filled with a liquid medium and is provided with at least one suction connection. The heating chamber is connected to the receiver, and the heating chamber has a receiving part for a capsule that contains the smoke medium. The receiving part is also a heating element for the capsule. Background Art

[0002] Originated from the Middle East, this type of hookah is also known as hookah pipe or hookah bag, and has become more and more popular among young people and teenagers in recent years, especially as a substitute for cigarettes. This hookah is known, for example, from US4031906 or US2012 / 0042884. This type of hookah has a receiver, which is partially filled with water or another liquid medium. The suction on the mouthpiece produces negative pressure in the receiver. In addition, the smoke column extends into the water for a specific distance, and the column has a head component for receiving tobacco at the top end of the column, and the tobacco is heated by the charcoal placed on the top. Then, the mixture of air, steam and smoke particles produced when the tobacco is heated is inhaled by the smoker. Obviously, using hot charcoal for heating may cause carbon monoxide poisoning, burning or fire in extreme cases. In addition, since the hookah is manually filled, it is not guaranteed that the hookah will be installed in a legal manner. In principle, the hookah, which is now called a hookah pipe, should therefore only be operated outdoors or indoors where fresh air supply is guaranteed. When constructed, hookah pipes according to the prior art are also very heavy and large, but must also be assembled from multiple parts, and it is cumbersome to transport the multiple parts of the hookah pipe in the form of individual parts of the hookah pipe. Cleaning these pipes is also a laborious process and often does not meet hygiene standards. US4,133,318 discloses an electronic hookah pipe, with which some of the above-mentioned problems can be reduced, but not to a satisfactory degree. The hookah pipe known from WO2017 / 080545 has proven to be particularly advantageous.

[0003] However, deficiencies still exist in the prior art with regard to the sensitive subject of effective heat transfer between a heating chamber into which the bladder is inserted and a capsule. Summary of the invention

[0004] The object of the present invention is therefore to provide a hookah, also known as a hookah pipe or hookah, which is characterized by a particularly effective and targeted transfer of heat between a heating chamber of the hookah and a capsule inserted into the heating chamber.

[0005] According to the invention, this object is achieved by means of a precise fit between the receiving portion and the capsule.

[0006] It is important to ensure efficient heat transfer between the heating chamber and the capsule, which is inserted into the heating chamber and filled with a liquid or solid medium, by means of a precise fit between the receiving part or a part of the receiving part on the one hand and the capsule on the other hand. In order to achieve an optimal smoking process, an ideal heat transfer from the heating chamber to the capsule is essential. This is achieved by precise thermal and geometric fixation and / or coordination of the three components, namely the heating chamber, the receiving part and the capsule.

[0007] The conical surface on the side of the receiving part or the side of the capsule is also very important in terms of precise fitting. This conical surface allows a particularly targeted heat transfer by means of a precise fit between the wall of the receiving part surrounding the side of the capsule and the capsule itself. The more firmly the capsule is located in the receiving part, the more effectively the heat is transferred from the outside, i.e. from the heating chamber, to the capsule. Here, a small amount of play can be allowed, but this small amount of play must not lead to the capsule rattling around in the receiving part. The receiving part thus serves to ensure that the capsule can be inserted into the hookah pipe, or more precisely, to ensure that the capsule is inserted into the heating chamber, wherein the receiving part also serves as a heating element for the capsule, wherein the wall surrounding the capsule is of particular significance.

[0008] In a particularly advantageous variant of this type of precise fit, the lateral wall of the receiving part tapers in a conical manner in the direction of the interior of the heating chamber, the angle of the taper being about 5° to 10°, preferably about 7°. If both the receiving part and the capsule have such a taper, a type of clamping fit of the capsule in the receiving part is achieved. After the constant diameter presents a small concave shape, on the side facing away from the interior of the receiving part, a correspondingly larger taper of the receiving part or capsule runs, wherein the small concave shape respectively extends parallel to the longitudinal axis of the receiving part or capsule.

[0009] The ideal geometry is achieved when the diameter of the receiving portion increases constantly between the front and rear of the receiving portion by a factor of about 1.1 to 1.25, preferably by a factor of about 1.17, or correspondingly the diameter of the bladder portion increases constantly between the front and rear of the bladder portion by a factor of about 1.1 to 1.25, preferably by a factor of about 1.17.

[0010] According to one embodiment of the invention, the receiving part has a front wall on its inner side, the front wall having an opening and extending substantially transversely to the longitudinal axis of the housing. The front wall forms the terminal end of the receiving part in the direction of the interior of the heating chamber.

[0011] In other directions of the receiving part, it is advantageous for the receiving part to have a covering ring on its outer side, which extends transversely to the longitudinal axis of the housing, in which the receiving part for the capsule is integrated. In other words, the covering ring and the heating chamber, respectively, are arranged and formed relative to one another in such a way that the covering ring has a central opening in which the capsule is located in the receiving part. At the same time, depending on the arrangement of the receiver, the heating chamber, etc., the covering ring forms the top end or the bottom end of the housing or the heating chamber.

[0012] Furthermore, the cover ring has the function of acting as an end stop for the collar on the side of the capsule when the capsule is inserted into the heating chamber. The cover ring thus ensures that the capsule fits in the heating chamber, in particular due to the fact that the capsule has a collar, with which it rests against the cover ring.

[0013] According to another constructional measure of the invention, the cover ring is connected to a collar provided on the outer side of the receiving part, or the cover ring is formed integrally with said collar. This collar on the receiving part enables a fixed connection between the receiving part and the cover ring to be provided as an additional element for integrating the receiving part for the capsule in the cover ring.

[0014] The importance of firmly fitting the capsule in the receiving part for the targeted transfer of heat to the capsule according to the present invention has been mentioned many times. Of course, it is now also necessary to keep the capsule with a lining at the back of the capsule so that the capsule does not slide out of the receiving part. On this basis, it is proposed that the heating chamber can be closed by means of a base plate or a cover plate, and the plate has an accessory located on the inner surface of the plate, which acts on the capsule to be inserted or already inserted. The air inlet is combined in the chamber, or in the plate or wall of the receiving part. When the plate is closed and therefore the heating chamber is also closed, the capsule according to the present invention finds the functional position of the capsule itself, that is, the end position of the plate inserted, latched, bolted, etc. corresponds to the capsule located in the functional position of the capsule, and smoking can begin in this functional position. In the case of removing the plate, the capsule is therefore inserted into the heating chamber from above or below according to the design of the hookah pipe, so that the capsule is fully received by the housing of the hookah pipe. The spent cartridge may then be removed from the chamber and replaced with a new cartridge filled with media.

[0015] These functions are supplemented by fittings on the inner face of the plate, which faces the receiving portion.

[0016] According to one proposal for such a fitting, the plate has an annular bead on its inner face, which is arranged and / or designed to correspond to the collar of the capsule. The diameter of the annular bead is therefore smaller than the diameter of the cover ring, the annular bead being located just opposite the collar of the capsule so that when the cover is closed, the annular bead automatically presses the capsule into the receiving portion.

[0017] As an additional fixing measure, the fitting is also equipped with a latching device. Specifically, this means that the annular flange has a latching device, which wedges into the capsule receiving portion and can therefore ensure an additional stable fitting of the capsule in the receiving portion, and therefore an additional stable fitting in the heating chamber.

[0018] For example, it is intended for the latching device to be arranged in a manner adjustable in the radial direction and in such a way that the latching device is wedged in the capsule receiving portion in the extended position.

[0019] According to another advantageous embodiment of the invention, the plate comprises a handle for actuating the plate on its outer face, whereby the plate can be rotationally biased by means of the handle, for example when assembling and disassembling the plate.

[0020] Due to the mechanism for pushing the used capsule out of its seat in the receiving part in a direction opposite to the insertion direction, the used capsule can be pressed out of its seat in the receiving part on the side of the heating chamber without the user having to touch the parts of the hookah that may have been exposed to high temperatures. Thus, the health hazard caused by the high temperatures of up to 200° C. that can be reached by the heated hookah capsule is eliminated, as is the case of the capsule getting stuck when being removed. Furthermore, any expansion process of the capsule is irrelevant, since the capsule can be pressed out of the receiving part in a particularly effective manner in a direction away from the reception. The fact that the mechanism can be operated from outside the heating chamber has the same purpose, which is specifically to obtain a sufficient distance between the user's hand and the heating chamber or the capsule in the heating chamber.

[0021] In an advantageous embodiment of the present invention, the smoking cartridge is arranged in a movably manner in the direction of the axial axis of the smoking cartridge. For this mechanism, this is a particularly optimal solution, because the smoking cartridge that always exists is given an additional function, which is used as a mechanism for releasing the capsule. In addition, the realization of this additional function is related to the completely safe removal of the high temperature of the capsule used in the heating chamber. A simple press on the smoking cartridge applies a force on the capsule in the direction opposite to the direction in which the capsule is inserted. Therefore, the capsule is released from the seat of the capsule in the receiving part on the side of the heating chamber. In order to improve handling, it is intended to be used to arrange the smoking cartridge in a movably manner in the direction opposite to the spring force, so that the smoking cartridge returns to the starting position of the smoking cartridge after being used to release the capsule, and the play of the smoking cartridge is limited during operation.

[0022] In addition, it is intended to connect the receiver and the housing part with the electronic unit to each other in a detachable manner, and to be provided with a valve in the region of the mouth of the smoking pipe in the receiver. The housing of the hookah mainly comprises a first housing part, a second housing part and a third housing part, the receiver being the first housing part, the second housing part holding the electronic device and the smoking pipe, and the third housing part holding the heating chamber for the capsule, advantageously comprising the first housing part, the second housing part and the third housing part in the order described from top to bottom. The receiver and the housing part holding the electronic unit are connected to each other in a detachable manner, and are also connected to each other by means of a valve that ensures additional sealing, thereby ensuring the hookah according to the invention in a particularly effective manner to prevent the escape of additional air. Preferably, the valve is arranged in the center, and optionally, parts of the valve protrude into the interior of the receiver. The valve has a precise fit on the smoking pipe that protrudes upward from the housing part. The smoking chimney is precisely fitted with the valve at the top end of the smoking chimney so that no additional air can escape anywhere in the entire area, wherein the smoking chimney leads into the heating chamber through the bottom end of the smoking chimney and the smoking chimney passes through the housing part. Specifically, the smoking chimney leads from below into the base of the receiver, which is generally designed to be strong enough to form a stable support for the valve and the end of the chimney. According to an advantageous embodiment of the invention, the base of the receiver has a cavity with a central mounting plate for fixing the combination of the smoking chimney. Therefore, the centrally positioned mounting plate located in the cavity of the originally relatively strong base serves as a support for the smoking chimney.

[0023] The invention is characterized in particular by creating a hookah (or hookah pipe or hookah bag) that is characterized by special compactness, safety, user-friendliness, easy cleaning and a variety of possible variations. The user first inhales into a heating chamber through an inlet on the top or bottom of the housing, in which a liquid or solid smoke medium containing or not containing tobacco is advantageously located in a capsule that will be inserted into a heating chamber in the form of an oven. As a result, the capsule is located to some extent in the airflow generated by the user at the top end of the housing by means of suction (i.e., by generating a negative pressure). At the same time, the solid or liquid smoke medium in the capsule is heated by means of a heating mechanism. Then, a mixture of air and smoke medium travels from the capsule inserted into the heating chamber through the smoking pipe and into an upper receiver, which is also called a water tank, where the mixture of air and smoke medium passes through water and can then be inhaled via a suction device. The precise fit between the receiving part and the capsule, in particular the precise fit between the chamber wall surrounding the side of the capsule and the capsule itself, facilitates the ideal heat transfer from the heating chamber to the capsule and thus the ideal smoke production. Since the lateral conical surfaces of the receiving part and the lateral conical surfaces of the capsule correspond to each other, a type of advantageous clamping effect is achieved. Alternatively or additionally, it is conceivable to use an adjustment member which, in its working position, exerts a clamping force on the capsule and thus keeps the capsule in place.

[0040] Figure 1 A hookah 1, also called a hookah pipe or hookah, is shown, which has a housing 2 of the hookah. The receptacle 3 is sealed at the top by means of a cover 41. A suction hose 34 is connected to a connection 33, which is part of the cover 41, via an integral end of the suction hose, and a replaceable mouthpiece 35 is provided at the other end of the suction hose. The mouthpiece can connect a plurality of hoses 34, 36. The water level for the water arranged in the receptacle 3 is indicated by 38, which is particularly advantageous when the receptacle 3 is only partially filled. The heating chamber and the battery as well as the control unit are concealed by the housing 42. The on / off / standby switch for operating the hookah is indicated by 39. 10, 10' are two capsules for containing the smoke medium, which have perforations 43. An air inlet in the form of a plurality of air gaps is indicated by 37.

[0041] Figure 2The receiving part 5 for the capsule 10 is shown. Here, the precise fit between the lateral wall 7 (outside) of the receiving part 5 and the wall 12 (inside) of the capsule 10 can be clearly seen. The two walls 7, 12 extend in the direction of the interior 8 of the heating chamber 4 in the form of a cone 15, i.e. preferably, the two walls 7, 12 extend in the direction of the interior 8 of the heating chamber 4 at an angle α of about 7°. The receiving part 5 comprises a front wall 19 on the inside 16 of the receiving part, which front wall has an opening and extends substantially transversely to the longitudinal axis of the housing and therefore also substantially transversely to the receiving part 5. A gap 44 can remain between the front wall 19 of the receiving part and the front wall 13 of the capsule. The ideal geometry is achieved when the diameter of the receiving part 5 increases continuously between the front part 6 and the rear part 9 of the receiving part 5 as viewed in the flow direction by a factor of about 1.1 to 1.25, preferably by a factor of about 1.17, or when the diameter of the capsule increases continuously between the front part and the rear part of the capsule by a factor of about 1.1 to 1.25, preferably by a factor of about 1.17, here from about 31 mm to about 36 mm. Here, the collar 11 can also be clearly seen, which in turn extends transversely to the longitudinal axis 21 on the outer side 14 of the receiving part 5. The receiving part 5 for the capsule is incorporated into a covering ring 22 on the outer side 17 of the receiving part.

[0042] Reference Figure 2 , Figure 3 Shown from Figure 2 of section AA, and on the other hand, Figure 3 From the outside to the inside, the components connecting ring 22 , the collar 11 , the wall 12 in the form of the cone 7 , the front wall 19 and the opening 18 are shown.

[0043] in addition, Figure 4 A perspective view of the housing part with the heating chamber and the capsule 10 inserted in the cover ring 22 is shown. The capsule 10 comprises a collar 11 which first enters into a groove 45 and then into a plate 46 with a perforation 43.

[0044] In accordance with Figure 5 Of particular importance in the representation of is the important interaction between the heating chamber 4, the receiving part 5, the wall 7, the wall 12 and the cover plate or base plate 24. The heating chamber 4 is closed by means of the base plate 24, the capsule 10 finally adopting its functional position when the base plate 24 is fixed, twisted or inserted in the heating chamber 4. The handle 29 is used to actuate the plate 24, here by means of rotation.

[0045] The handle Figure 6 29 is also indicated in the figure. Accordingly, AA indicates that then Figure 5 The cross section shown in .

[0046] According to the plate 24 shown Figure 7 The plate 24 comprises a fitting 27 in the form of an annular flange 28 on its inner face 25 and a handle 29 on its outer face 26. Latching means are indicated by 30 and are used to additionally wedge the cover 24 into a receiving portion (not shown here).

[0047] Figure 8 A view of the inner face 25 of the cover 24 is shown, with a fitting 27 in the form of an annular flange 28 corresponding to a collar of the bladder (not shown here).

[0048] Fig. 9 Shows Fig.10 , in the form of a receiving part integrated in a covering ring 22. The covering ring 22 is connected to a collar 23 on the side of the receiving part. At the same time, the capsule 10 is particularly firmly seated in the receiving part 5 by its collar 11, due to the uniform taper of about 7°. It must also be mentioned that, for the purpose of adapting to the covering ring 22, the capsule 10 has a section 31 between the collar 11 and the wall 20 of the capsule itself, the wall 20 of the capsule 10 extending in this section exactly parallel to the longitudinal axis 21.

[0049] Fig.11 The already discussed section 31 between the collar 11 and the wall 12 in the capsule 10 is shown again. The same applies to Fig.12 .

[0050] therefore, Fig.13 A bladder 10 is shown having a tapered wall 12 between a collar 11 and an outlet 47 .

[0051] Fig.14 A cross-sectional view is shown. Reference numeral 61 is used to represent a smoking tube, which can be moved in the direction of a longitudinal axis 63, wherein pressure will be applied to the smoking tube 61 manually or via a controller in the direction of arrow 60. The smoking tube 61 has two tube parts 62, 64 of different diameters. The diameter of the inner part 62 of the smoking tube 61 facing the heating chamber 4 is smaller than the diameter of the outer part 64 facing the receiver (not shown here), so that a bushing 67 or a stopper acting on the spring 66 is formed when the smoking tube 61 is pushed. It is also conceivable to provide an inner tube 58 with corresponding parts 62, 64. In addition, the inner tube part 62 is surrounded by a compression spring 66, or the spring shaft 59 is incorporated in the wall 68 of the heating chamber 4 facing the receiver. It can be clearly seen here that the inner tube part 62 protrudes into the heating chamber 4 through the front end 65 of the inner tube part. The guide bolt for the smoking tube 61 is indicated by 69.

[0052] also, Fig.15 Shown is a section through the hookah 1. The housing part is located in the center and at the bottom is the heating chamber 4 with a receiving part 5 for the capsule 10 and a removable base plate 24. The threaded connection ensures that when the two parts are put together, the centrally located valve 48 is automatically positioned, wherein the valve is in the base 54 of the receiver or protrudes a certain distance into the receiver interior 53. Fig.15 The solid, multi-layer design of the base 54 of the receiver 3 is shown. The mouth 57 of the extraction tube 61 is secured by means of three seals in the form of O-rings 49, 50, 51. The valve 48 and the extraction tube 61 are located on a common longitudinal axis 52. The cavity incorporated into the base 54 is designated by 55 and serves to receive a central mounting plate 56 into which the extraction tube 61 then specifically opens.
