Description

The invention relates to a hookah with a body in which a container to be filled with liquid and having at least one suction connection and a heating chamber connected to it by means of a suction hose are combined, the heating chamber having a receiver for a capsule that serves to contain substances for the formation of smoke.

The hookah, also known as shisha or huka, comes from the East. Such hookahs are known, inter alia, from US 4031906 or US 2012/0042884. Hookah is gaining more and more popularity, especially among teenagers and young people, in particular, as an alternative to cigarettes. These hookahs contain a container that must be partially filled with water or other liquid. Suction through the mouthpiece creates a negative pressure in the container. In addition, a smoke shaft partially protruding into the water is provided, which has an upper section at the upper end for receiving tobacco, which is heated by charcoal lying on top of the upper section. The smoker inhales the mixture of air, vapor and smoke particles that is formed when tobacco is heated. It is understood that heating with hot charcoal can lead to carbon monoxide poisoning, fire hazards or, in extreme situations, even fire. Since hookahs are filled by hand, it is impossible to ensure their high-quality filling that meets legal requirements. In principle, currently known hookahs can only be used outdoors or indoors with a guaranteed supply of fresh air. In addition, prior art hookahs are also relatively large in weight and volume, they must be assembled from several parts, and transportation of individual parts creates difficulties.

Electronic hookahs are known from US 4,133,318 or US 12/0,199,572, which can reduce some of the above problems, although not yet to a satisfactory extent. Finally, the subject of WO 2017/080545 is an electronic hookah in which a capsule for containing a solid or liquid substance to generate smoke is placed in a receiver which is part of the device. This receiver has a wall tapering towards the container and closing the capsule from the sides, i.e. the receiver is also made in the form of a heating chamber for the capsule. It has been confirmed that the standard removal of capsules from hookah heated to 200°C is dangerous, especially when it is associated with a high likelihood of burns. In addition, removal is also difficult because the raw material in the capsule expands during heating and returns to normal size only after complete cooling. However, even chilled capsules are relatively difficult to remove because the capsule is caught at the shoulder serving as a stop for the capsule and must be pulled out of the receptacle. Last but not least, this process is labor intensive.

Thus, the object of the present invention is to provide a hookah where the used capsules can be easily removed from the heating chamber and/or from the receiver.

This problem is solved by using a mechanism for pushing the used capsule out of the socket of the receiver in the opposite direction to the insertion direction.

With this mechanism, used capsules can be ejected from the receptacle on the side of the heating chamber without the user coming into contact with parts of the hookah or capsule that can reach high temperatures. Thus, the risks of a negative impact on the health of users due to high temperatures up to 200 ° C, to which hookah capsules can heat up, for example, when the capsule is jammed during pulling out, are excluded.

Capsule expansion processes are also irrelevant since the capsules can be pushed out of the receptacle away from the container in a particularly efficient manner.

The ability to control said mechanism from outside the heating chamber serves the same purpose, in particular to ensure sufficient distance between the user's hand and the heating chamber and/or the capsule inside the heating chamber to prevent burns.

In this regard, an advantageous embodiment of the invention provides a suction hose which is supported for sliding movement in the direction of its longitudinal axis. This solution is particularly advantageous with respect to a mechanism of this kind, in the sense that the existing suction hose in any case has an additional function and serves as a mechanism for ejecting the capsules. In fact, this is carried out from a completely safe distance, taking into account the high temperature of the used capsules in the heating chamber. By simply pressing on the suction hose, force is applied to the capsule in the opposite direction in which it is inserted. Accordingly, the capsule is inevitably released from the seat in the receptacle on the side of the heating chamber and can be easily grasped.

For more convenient handling, the invention provides that the suction hose is slidably supported against spring resistance, so that the suction hose returns to its original position after use to release the capsule, and the free movement of the suction hose during use of the hookah is limited.

In this sense, the proposal that the suction hose is equipped with a tube with two sections of different diameters should also be understood. This provides for the formation of a cavity along the spring for the suction hose or other mechanism.

A design with an inner tube having two sections of different diameters in front of the suction hose is provided as an alternative to a separate suction hose with two sections of different diameters.

For this purpose, an inner tube is attached to the suction hose, which, in turn, has two sections of different diameters, which allows the use of a standard suction hose to actuate the inner tube. Thus, the first embodiment of the invention relates to a one-piece suction hose with two sections of different diameters, and the second embodiment relates to a suction hose with an inner tube, the latter having two sections of different diameters.

In this regard, it is advantageous if the inner tube/hose section is surrounded by a compression spring, so that a spring support is provided in the transition zone.

Specifically, this means that the section of the suction hose or inner tube facing the heating chamber has a diameter smaller than the diameter of the section of the suction hose or inner tube facing the vessel, and thus a shoulder is formed against which the spring rests during movement of the suction hose. This stage or stop ensures that the spring is compressed when the suction hose is suitably actuated to release the capsule and returns to its original position.

A particularly suitable embodiment of the invention provides for a cavity in the wall of the heating chamber facing the vessel. The cavity for the spring, made in the wall, limits the free movement of the spring.

The purpose of the suction hose or other mechanism has already been described several times above. Thus, the suction hose, specifically the inner section of the hose or the inner tube, continues into the heating chamber and, depending on the pressure on the suction hose, slides into the heating chamber and, ultimately, ejects the capsule from the seat of the receiving area.

In addition, it is provided that the suction hose and/or the inner tube must be slidably supported in a guide fixedly attached to the heating chamber. This guide in the form of a sleeve is attached to the heating chamber, more precisely, to the wall facing the container. In the installed state, for example, this guide is surrounded by an electronic unit and / or a hookah controller.

Another advantageous embodiment of the invention provides a mechanism to be operated manually and/or by an electronic hookah controller. The first manual variant has already been described exhaustively, and in the case of the electronic controller as the second variant, the printed circuit board performs electronic control of a mechanism commensurate with a push rod that drives the suction hose, or a separate rod that ultimately ejects the capsule from the nest.

The aim is to ensure a high degree of heat transfer efficiency between the heating chamber and the capsule inserted into the heating chamber, which can be achieved by tightly mating the receiver or parts of this receiver on the one hand and the capsule on the other hand. Tapering is essential for such tight mating. This allows for a specific desired heat transfer due to the tight interface between the walls of the receiver, which surround the sides of the capsule, and the capsule itself. In fact, the more tightly the capsule is located in the receiver, the more efficient is the transfer of heat from the outside, i.e. in the direction from the heating chamber to the capsule. A particularly advantageous embodiment of such a tight interface is one in which the side wall of the receptacle tapers towards the inside of the heating chamber with a taper angle of approximately 5° to 10°, preferably approximately 7°. The ideal geometry is achieved when the receiver diameter between the front and back sides of the receiver or capsule is constantly increasing by a factor of approximately 1.1 to 1.25, approximately 1.17 times.

According to the design according to the invention, the receptacle comprises, on the outside, a fastening ring extending at right angles to the longitudinal axis of the housing, into which the receptacle for the capsule is integrated, i.e. the attachment ring and the heating chamber are shaped and positioned to match each other, and the attachment ring has a central hole into which the capsule is placed in the receptacle. However, depending on the location of the tank, heating chamber, etc. the fastening ring forms the upper or lower end of the housing or heating chamber. In addition, the attachment ring also serves as a stop for the annular protrusion on the side of the capsule when the capsule is inserted into the heating chamber. Thus, the attachment ring ensures that the capsule is positioned in the heating chamber, in no small part because the capsule has an annular protrusion with which it abuts against the attachment ring.

In addition, a container and a housing part containing an electronic unit are provided, connected with the possibility of disassembly, and a valve in the area where the suction hose outlet opens into the receiver. The hookah body essentially consists of a container as the first body part, a second body part containing the electronic components and a suction hose, and a third body part containing the capsule heating chamber, preferably in that order from top to bottom. In this regard, the container and the body part containing the electronic assembly are connected to each other with the possibility of disassembly and are additionally connected by a valve that provides additional sealing, which is a particularly effective way to protect the hookah according to the invention from leakage of additional air. The valve is preferably located centrally and, if necessary, part of the valve extends into the interior of the container. The valve must be tightly connected to the suction hose protruding upwards from the specified part of the body. The suction hose, the lower end of which is open into the heating chamber and passes through a part of the housing, is connected to the valve at its upper end by means of a tight interface so that additional air does not escape over the entire connection area. Specifically, this means that the suction hose exits from below into the base of the tank, so the base must be of solid construction and form a stable mounting support for the valve and hose end.

In this regard, an expedient embodiment of the invention is an embodiment in which the container has a hollow space with an integrated central mounting plate for fixing the suction hose. The mounting plate, centrally located in the hollow space, other things being equal, relative to a solid base, serves as a mounting support for the suction hose.

In particular, the present invention is characterized in that a particularly suitable mechanism is configured to release used, but possibly still very hot, smoke-generating substance-containing capsules from the heating chambers and/or the receiving areas located therein. Instead of the difficult detachment of such a capsule from the socket in the receiver by pulling the capsule by its annular ledge with a hand, knife, etc., a suction hose is used, which is present in any case, or another structural element in the form of a rod, having a dual purpose, to additionally provide ejection of the capsule from the socket of the receiver. To this end, the suction hose is supported for sliding movement, overcoming the resistance of the spring, and in the wall of the heating chamber facing the container, a cavity for the spring is formed. As an alternative to this mechanical design solution, the use of a controller is envisaged to provide appropriate movement of such a mechanism to eject the capsule.

Other features and advantages of the subject matter of the invention will become apparent from the following description of the attached drawings, which show an example of a preferred construction with partial views and images of individual parts. On the drawings:

in fig. 1 - front view of the hookah;

in fig. 2 - top view of the heating chamber with a suction hose;

in fig. 3 is a perspective view referring to FIG. 2;

fig. 10 - section along the opening of the suction hose.

In FIG. 1 shows hookah 1, also known as shisha or huka. The design of the hookah 1, which has an elongated body 2, is modular and very compact. The container 3 is closed at the top with a lid 21. The suction hose 22 is connected at one end to a connecting pipe 23, which is part of the lid 21 and contains a replaceable mouthpiece 24 at the other end. Several hoses can be connected. Position number 25 indicates the level of water contained in tank 3, since only partial filling of tank 3 is allowed. perforated holes 27 containing a substance for generating smoke. The air inlet in the form of several slots is indicated by the item number 28.

In addition, in FIG. 2 and 3 show a top view of the heating chamber 4 with a suction hose 6 which is placed in a guide 15 in the form of a sleeve.

In FIG. 4 is a sectional view taken along line A-A in FIG. 2. The reference number 6 denotes a suction hose that can be slidably moved in the direction of the longitudinal axis 8, and for this purpose pressure must be applied to the suction hose 6 manually or by means of a controller in the direction of the arrow 40. The suction hose 6 has two sections of different diameters. In this regard, the section of the suction hose 6 that faces the heating chamber 4 has a smaller diameter than that of the section facing the container, which is not shown here, so that a shoulder or stop 13 is formed which depresses the spring 7 during the movement of the suction hose 6. Thus , the second section is surrounded by a compression spring 7 at the end 16 facing the first section, and in the wall 17 of the heating chamber 4 facing the container, a cavity 18 is made for the spring.

In the figure under consideration, it is clearly seen that the front end 19 of the second section continues into the heating chamber 4.

In FIG. 5 shows the location from FIG. 4, which shows the suction hose 6 and the inner tube 14. The inner tube 14 has a shoulder 13, since the diameter of the said tube passing through the spring cavity 18 at the front end of the tube is smaller than the diameter of the tube at its rear end. In FIG. 5 clearly shows that the spring is located in the wall 17, which, in turn, is the outer limit of the cavity 18 for the spring.

In FIG. 6 and 7 are views related to the above description. In FIG. 7 shows the receiver 5 for the capsule 10. At the same time, the nest for dense installation of the wall 31 of the capsule 10 at the side wall 30 (outer) of the receiver 5 is clearly visible. Both walls 30, 31 continue to the inner side 32 of the heating chamber 4 in the form of a cone 33 .e. at a preferred angle α of approximately 7°. On the inside, the receiver 5 has an end wall 34 with a hole, which extends essentially at right angles to the longitudinal axis of the body 2, as well as the receiver 5. Between the end wall 34 of the receiver 5 and the end wall 35 of the capsule 10 may remain free space 36. Also clearly visible is the annular protrusion 37, which in turn extends at right angles to the longitudinal axis from the outside of the receiver 5. The attachment ring 38 is included in the housing.

In FIG. 7 is a sectional view taken along line A-A in FIG. 6 and in FIG. 6 from the outside to the inside shows the fastening ring 38, the collar 37, the wall 30, 31 (tapered), the end wall 34 and the hole 39.

In FIG. 8 shows the area circled in FIG. 9 in the form of incorporating the receiver into the attachment ring 41. The fastening ring 41 is connected to the collar 42 on the side of the receiver. At the same time, the capsule 10 with the annular projection 43 is in the receptacle 5 and fits very tightly against it due to a uniform conical constriction of approximately 7°.

It should also be noted that, in order to match the attachment ring 41, the capsule 10 has a section 45 between the collar 43 and its actual wall 44, the wall of the capsule 10 extending exactly parallel to the longitudinal axis 46.

In addition to the above description in FIG. 10 shows a hookah 1 in section. The base section is located in the center, and below it is a heating chamber with a capsule receiver and a removable base. When these two components are assembled, the thread provides automatic positioning of the centrally placed valve 48, which is located in the base 54 of the container and continues for some distance into the interior 53 of the container. In FIG. 3 shows the solid multi-layer construction of the base 54 of the container 3. At the opening 57 of the suction hose 6, three seals in the form of O-rings 49, 50 and 51 are installed for fastening. The valve 48 and the suction hose 6 are located on a common longitudinal axis 52. In the base 54 there is a hollow space, indicated by the reference number 55, which serves to accommodate the central mounting plate 56, into which the suction hose 6 actually extends.
