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 used to be filled with a liquid medium and is equipped with at least one suction connection piece, and the heating chamber is connected to the receiver via a suction hose, whereby the heating chamber includes a receiving part for a capsule-like piece, which is used to hold the smoke medium. Background Art

[0002] The hookah, also known as a hookah pipe or hookah, originally comes from the Eastern region. This hookah is known from US4031906 or US2012 / 0042884, etc. The hookah is becoming more and more popular, especially among young people and teenagers, and the hookah is particularly used as a substitute for cigarettes. This hookah has a receiver, which is designed to be partially filled with water or another liquid medium. The pressure of the suction at the mouthpiece in the receiver is reduced. There is also a smoke column extending into the water for a certain distance, and the smoke column has a top part at the upper end of the smoke column to hold tobacco, which is heated by charcoal placed on the top of the smoke column. Then, the mixture of air, steam and smoke particles formed by heating the tobacco is inhaled by the smoker. In this regard, it is obvious that carbon monoxide poisoning, accidental combustion or even fire in extreme cases may occur due to heating by red-hot charcoal. Since the hookah pipe is manually filled, it is impossible to ensure the quality and legal compliance of the hookah pipe. In principle, therefore, the hookah pipes known today should only be operated outdoors or indoors with a fresh air supply. In addition, hookah pipes constructed according to the prior art are very heavy and large, need to be assembled from multiple parts, and are not convenient to transport in the form of individual parts of the hookah pipe.

[0003] Electronic hookah pipes are known from US 4,133,318 or US 12 / 0,199,572, by which some of the above problems can be reduced, although not yet satisfactorily. Finally, the subject of WO 2017 / 080545 is an electronic hookah pipe, in which a capsule for containing a solid or liquid smoke medium is placed in a receiving part as part of the device. The receiving part comprises a wall portion that narrows toward the receiver and closes the capsule at the side, whereby the receiving part is simultaneously designed as a heating element for the capsule. Conventional removal of hookah capsules heated to up to 200° C. has proven to be dangerous, especially because the removal is associated with a great risk of burning. In addition, removal is still difficult because the capsule raw material expands during the heating phase and shrinks back to normal size only after the capsule raw material has completely cooled. However, even the already cooled capsule is relatively difficult to remove, since the capsule grips on a shoulder which is intended as an end stop for the capsule and the capsule has to be pulled out of the receiving portion. Last but not least, all of this is laborious. Summary of the invention

[0004] The object of the present invention is therefore to create a hookah with which a used capsule can be easily removed from the heating chamber and / or the receiving part.

[0005] This object is achieved by a mechanism which ejects the used capsule from its seat in the receiving portion in a direction opposite to the insertion direction of the capsule.

[0006] Thanks to this mechanism, the used capsule can be ejected from its seat in the receiving portion on the side of the heating compartment without the user coming into contact with the hookah or with portions of the capsule that could be exposed to high temperatures. Thus, health hazards due to the high temperatures of up to 200° C. that a heated hookah capsule can present are eliminated, while the capsule getting stuck when being pulled out is also eliminated.

[0007] Any possible expansion process of the capsule is also unimportant, since the capsule can be ejected particularly effectively from the receiving part in the direction away from the receiver.

[0008] The fact that the mechanism is operable from outside the heating chamber is intended in the same direction, namely good handling and creating a sufficient distance between the operator's hand and the heating chamber and / or the capsule located therein, for example to avoid burns.

[0009] In this respect, an advantageous embodiment of the invention provides that the suction hose is supported so as to be able to slide in the direction of its longitudinal axis. This is a particularly optimal solution for a mechanism of this type, since the existing suction hose is in any case given an additional function, namely as a mechanism for ejecting the capsule. In practice, this is done from a completely harmless distance with respect to the high temperatures of the used capsule in the heating chamber. Simply pressing the suction hose will exert a force on the capsule in a direction opposite to the direction in which the capsule was inserted. The capsule must therefore be released from its seat in the receiving portion on the side of the heating chamber and can be easily picked up.

[0010] For even better handling, the aim is to support the suction hose slidably against the force of the spring, whereby the suction hose returns to its initial position after being used to release the capsule and the free play of the suction hose is limited during operation.

[0011] In this sense, the suggestion of showing two parts with different diameters according to the suction hose is also to be understood. This results in the formation of a spring shaft for the suction hose or another mechanism.

[0012] The arrangement of an inner pipe piece having two sections with different diameters in the front part of the suction hose is to be understood as an alternative to a single suction hose having two sections with different diameters.

[0013] For this purpose, the suction hose is assigned an inner tube which in turn presents two portions of different diameters in order to allow the use of a standard suction hose operating the inner tube. Thus, a first embodiment of the invention relates to a one-piece suction hose having two portions of different diameters, and a second embodiment relates to a suction hose plus an inner tube, whereby the inner tube has two portions of different diameters.

[0014] In this respect, it is advantageous if the inner tube / hose section is surrounded by the compression spring, so that a spring support is formed in this transition region.

[0015] In particular, the diameter of the tube portion of the suction hose or inner tube facing the heating chamber is smaller than the diameter of the outer tube portion of the suction hose or inner tube facing the receiver, thereby forming a shoulder against which the spring acts when the suction hose moves. When the suction hose is correspondingly operated to release the capsule, the transition or end stop enables the spring to compress and return the suction hose to its initial position.

[0016] A particularly suitable variant of the invention is achieved by integrating the spring shaft into the wall of the heating chamber facing the receptacle. The spring housing integrated into the wall thus limits the free displacement of the spring.

[0017] The function of the suction hose or other mechanisms has been discussed many times. Therefore, it is logical that the suction hose, in particular the inner part of the hose or inner tube, extends into the heating chamber and slides further towards the interior of the heating chamber according to the pressure on the suction hose to finally achieve the capsule being pressed out of its seat in the receiving part.

[0018] In addition, it is provided that the suction hose and / or the inner tube is supported in a slidable manner in a guide bolt fixedly attached to the heating chamber. The cylindrical guide bolt is attached to the heating chamber, more precisely to the wall facing the receptacle. In the installed state, for example, the bolt is surrounded by an electronic unit and / or a controller for the hookah.

[0019] Another advantageous embodiment of the invention provides that the mechanism is actuated manually and / or via the electronic controller of the hookah. The first manual variant has already been fully described, and in the case of the electronic controller as a second embodiment, the printed circuit board electronically controls a mechanism similar to a compression mold, which is provided to move a suction hose or a separate rod which ultimately ejects the capsule from its seat.

[0020] The aim is to ensure an efficient heat exchange between the heating chamber and the capsule inserted into the heating chamber, which is achieved by a precisely fitted seating between the receiving part or parts of the receiving part on the one hand and the capsule on the other hand. The cone or taper is crucial for the precisely fitted seating. Due to the precisely fitted seating between the wall of the receiving part surrounding the side of the capsule and the capsule itself, this allows a particularly targeted heat transfer. In fact, the more firmly the capsule is located in the receiving part, the more effectively the heat reaches the capsule from the outside, i.e. from the heating chamber towards the capsule. A particularly advantageous variant for this precisely fitted seating is arranged so that the lateral walls of the receiving part taper conically towards the interior of the heating chamber, whereby the angle of the cone or taper is about 5° to 10°, preferably about 7°. The ideal geometry is achieved when the diameter of the receiving part increases constantly by a factor of approximately 1.1 to 1.25, preferably by a factor of approximately 1.17, between the front and rear of the receiving part, respectively, and the diameter of the capsule increases constantly by a factor of approximately 1.1 to 1.25, preferably by a factor of approximately 1.17, between the front and rear of the capsule, respectively.

[0021] According to a development of the invention, it is provided that the receiving part has a closed ring at the outside of the receiving part, which extends at right angles to the longitudinal axis of the housing and into which the receiving part for the capsule is integrated, i.e. the closed ring and the heating chamber are arranged and shaped to correspond to each other so that the closed 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 closed ring forms the upper end or the lower end of the housing or the heating chamber, respectively. In addition, when the capsule is inserted into the heating chamber, the closed ring acts as a stop for the lining on the side of the capsule. The closed ring thus ensures that the capsule is seated in the heating chamber, in particular because the capsule has a lining, through which the capsule contacts against the closed ring.

[0022] In addition, it is provided that the receiver and the part of the housing accommodating the electronic unit are connected together in a detachable manner, and a valve is provided in the area where the suction hose leads into the receiver. The housing of the hookah mainly comprises a first housing part, a second housing part and a third housing part, the first housing part being the receiver, the second housing part accommodating the electronic device and the suction hose, and the third housing part accommodating the heating chamber for the capsule, advantageously comprising the first housing part, the second housing part and the third housing part in the described order from top to bottom. In this regard, the receiver and the housing part accommodating the electronic unit are connected to each other in a detachable manner, and additionally, are connected to each other by a valve ensuring an additional seal, which protects the hookah according to the invention particularly effectively from the escape of bypass air. Preferably, the valve is arranged in the center, and if necessary, part of the valve extends into the interior of the receiver. The valve is located on the suction hose extending upwards out of the housing part by precise fitting. The suction hose is connected to the valve at its lower end, which leads into the heating chamber and through the housing part, by a precise fit so that no bypass air can escape in this entire area. Specifically, it seems that the suction hose leads from below into the receiver base, whereby the base must be designed entirely in large size in order to form a stable support for the valve and the end of the chimney here.

[0023] In this respect, an advantageous embodiment of the invention is one in which the base of the receiver has a hollow cavity with a central attachment plate for fixing a suction hose. Thus, the attachment plate centrally positioned in the hollow cavity of the originally relatively large base serves as a support for the suction hose.

[0024] In particular, the invention is characterized in that a particularly suitable mechanism is created to release a used but possibly still very hot capsule to contain a smoke medium from a heating chamber and / or a receiving part positioned at the heating chamber. Instead of using the hands, a knife, etc., to clumsily separate such a capsule from its seat in the receiving part by pulling on a lining, a suction hose or other rod-shaped structural element, which is present in any case, serves a dual function to additionally enable the capsule to be pressed out of its seat in the receiving part. For this purpose, the suction hose is supported to be slidable against the force of a spring, whereby the spring housing is incorporated into the wall of the heating chamber facing the receiver. An alternative to this mechanical solution presupposes a controller which ensures a corresponding movement of such a mechanism to press out the capsule. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1A hookah 1, also known as a hookah pipe or hookah, is shown. The structure of the hookah 1 is particularly compact, the hookah having an elongated housing 2 and having a modular design. A receptacle 3 is closed at the top by a cover 21. The integral end of a suction hose 22 is connected to a connection 23 which is part of the cover 21 and the integral end of the suction hose is equipped with a replaceable mouthpiece 24 at the other end. The connection of multiple hoses can be envisaged. The water level of the water contained in the receptacle 3 is indicated by 25, which is particularly advantageous when the receptacle 3 is only partially filled. The opening, closing and standby switches for operating the hookah 1 are indicated by 26. Two capsules having a perforated portion 27 and holding a smoke medium are indicated by 10, 10'. The air inlet in the form of a plurality of air gaps carries the reference numeral 28.

[0037] also, Figure 2 and Figure 3 The plan view of the heating chamber 4 is shown, which has a suction hose 6 which is carried in a cylindrical guide bolt 15 .

[0038] Figure 4 Indicates along Figure 2 4. A cross section taken along AA in FIG. 4. Reference numeral 6 denotes a suction hose which can be slid in the direction of the longitudinal axis 8, for which purpose pressure must be applied to the suction hose 6 by hand or by a controller in the direction of the arrow 40. The suction hose 6 has two chimney parts 11 and 12 of different diameters. In this respect, the diameter of the part 12 of the suction hose 6 facing the heating chamber 4 is smaller than the diameter of the part 11 facing the receiver (not shown here), so that a shoulder or end stop 13 is formed which acts on the spring 7 when the suction hose 6 is moved. Therefore, the second chimney part 12 is surrounded by the compression spring 7 at its end 16 pointing toward the first chimney part 11, and the spring shaft 18 is incorporated into the wall 17 of the heating chamber 4 facing the receiver.

[0039] The fact that the front end 19 of the second chimney part 12 extends into the heating chamber 4 is easily recognizable.

[0040] Figure 5 is an enlarged view showing the Figure 4 Detail of the view with the suction hose 6 and the inner tube 14. The inner tube 14 has a shoulder 13 formed by the inner tube 14, which has a smaller diameter at its front end than at its rear end, thus forming a spring shaft 18. The fact that the spring is accommodated in the wall 17 is Figure 5 As can also be easily recognized in FIG. 1 , this wall then again represents the outer closure of the spring shaft 18 .

[0041] Then, Figure 6 and Figure 7 This result is shown. Figure 2 The receiving part 5 for the capsule 10 is shown. At the same time, the precisely fitted seating between the side wall 30 (outside) of the receiving part 5 and the wall 31 of the capsule 10 is easily recognizable. Both walls 30, 31 extend towards the interior 32 of the heating chamber 4 in the shape of a cone 33, i.e. at a preferred angle α of about 7°. The receiving part 5 comprises an end wall 34 at the inner side of the receiving part, which has an opening and extends essentially at right angles to the longitudinal axis 8 of the housing 2 and therefore also at right angles to the longitudinal axis of the receiving part 5. A free space 36 can be retained between the end wall 34 of the receiving part 5 and the end wall 35 of the capsule 10. The lining 37 is also easily recognizable, which in turn extends at right angles to the longitudinal axis 8 at the outer side of the receiving part 5. A closing ring 38 is incorporated into the housing.

[0042] Reference Figure 6 , Figure 7 Shows Figure 6 of cross section AA, and on the other hand, Figure 7 The components closure ring 38 , collar 37 , walls 30 , 31 (conical portion), end wall 34 and opening 39 are shown from outside to inside.

[0043] Figure 8 Shows Fig. 9 The circled detail in the figure is in the form of the receiving part being integrated into the closed ring 41. The closed ring 41 is connected to the collar 42 on the receiving side. At the same time, the capsule 10 is located in the receiving part 5 via its collar 43 and is particularly tightly located in the receiving part 5 due to the uniform taper / contraction of about 7°.

[0044] It must also be mentioned that, in order to fit to the closing ring 41 , the capsule 10 has a portion 45 between the collar 43 and the actual wall 44 of the capsule, the wall of the capsule 10 in this portion 45 extending completely parallel to the longitudinal axis 46 .

[0045] In addition to this, Fig.10 A cross section through the hookah 1 is shown. In the center is the housing part and below it is the heating chamber with a receiving part for the capsule and a removable base plate. When these two parts are put together, the thread automatically ensures the positioning of the centrally located valve 48, which is in the base 54 of the receiver and extends a certain distance into the receiver interior 53. Fig.10The overall multi-layer structure of the base 54 of the receiver 3 is shown. The opening 57 of the suction hose 6 is secured by three seals in the form of O-rings 49, 50, 51. The valve 48 and the suction hose 6 are located in a common longitudinal axis 52. The hollow cavity incorporated into the base 54 and indicated by 55 accommodates a central fastening plate 56, into which the suction hose 6 then actually opens.
