Description

DESCRIPTION

Hookah with connection between the tank and the housing

The invention relates to a water pipe with a housing in which a container to be filled with a liquid medium and provided with at least one suction connection and a heating chamber connected to the latter via a suction pipe are integrated, the heating chamber being a receptacle for holding a smoke medium serving capsule. Also known as hookahs or hookahs, water pipes originally come from the oriental region. Last but not least, they enjoy as

Alternative to cigarettes has become increasingly popular, especially among young people and adolescents. Such hookahs are u. a. known from US 4031906 or US 2012/0042884. Such

Hookah has a container to be partially filled with water or another liquid medium. Sucking from a mouthpiece causes suppression in this container. A piece of smoke also protrudes into the water, which has a head part at its upper end for receiving tobacco, which is heated with coal lying on it. The mixture of air, steam and smoke particles created when the tobacco is heated is then drawn in by the smoker. It is obvious that there is carbon monoxide poisoning due to heating by red-hot coal

Burn accidents or, in extreme cases, even the outbreak of fire. Such classic hookahs are from the US, among others

2014 / 0.069.446 or US 2012 / 0.042,884. The legally compliant fitting of the water pipes is often not guaranteed due to the manual filling to that of hookahs. In principle, today's hookahs should therefore only be operated outdoors or in rooms with guaranteed fresh air supply become. Such state-of-the-art hookahs are also relatively heavy and voluminous, have to be assembled from several parts and are difficult to transport in their details. Cleaning is also complex and often does not meet hygienic standards. From the US

4,133,318, for example, electronic shishas are then known, but some of the problems mentioned above cannot be reduced satisfactorily. The shishas known from WO 2017/080545 have also proven to be particularly advantageous. However, there are still deficits in the prior art due to the escape of air in the area of the connection between the water tank and the housing of the hookah. This proves itself

Transition out of the container as a kind of predetermined breaking point

corresponding impairments regarding handling and smoking experience.

The present invention therefore has the task of creating a hookah which is characterized by high tightness and thus effectiveness for the smoking experience.

This object is achieved in that the container and a

Electronics unit receiving housing part are detachably connected to each other and that a valve is provided in the region of the mouth of the suction pipe in the container.

The housing of the hookah essentially consists of the container as the first housing part, the second housing part receiving the electronics such as the suction pipe and the third housing part receiving the heating chamber for the capsule, expediently in the order mentioned from top to bottom. The container and the housing part receiving the electronics unit can be detached from one another and additionally by an improved one

Seal ensuring valve connected, which secures the hookah according to the invention in a particularly effective manner against the escape of secondary air. For this purpose, the valve is preferably arranged centrally and, if necessary, a part of it projects into the interior of the container. It has already been mentioned that the container is located above the housing part receiving the electronics unit. The proposal that the valve sits precisely on the suction pipe protruding upward from the housing part is understood in this sense. The suction pipe, which opens into the heating chamber with its lower end, and which the electronics unit

through the receiving housing part, is connected at its upper end to the valve so that there is no leakage of secondary air in this entire area.

Specifically, this means that the suction pipe opens into the bottom of the container from below, the bottom being so massive that a stable bearing for the valve and the end of the pipe is formed.

An expedient embodiment of the invention is that in which the bottom of the container has a cavity with an integrated central

Has mounting plate for fixing the intake manifold. As a warehouse for that

The suction pipe is used for the fastening plate centrally positioned in the cavity of the otherwise comparatively solid floor.

In addition, it is provided that the suction pipe in the

Mounting plate opens. So the suction pipe ends in the container,

preferably in the bottom and in a particularly advantageous manner in the mounting plate integrated in the container bottom.

It is understood that the suction pipe and the valve are arranged in the longitudinal axis of the hookah, so that the suction pipe when assembling the container and housing z. B. after cleaning, finds its position directly in the valve.

This type of storage between the suction pipe and valve makes it appear advantageous if the mouth of the suction pipe is in the bottom of the container Seals is provided. These seals seal between the suction pipe and the tank bottom and / or the fastening plate seated in the cavity, so that a reliable and safe airway via the suction pipe and its connections is definitely guaranteed without losses.

It has already been mentioned that the container and the housing part receiving the electronics are detachably connected to one another. A preferred embodiment of the invention provides that the container and the housing part receiving the electronics are connected to one another at the edges, this is then supplemented by the precise fit between the top of the suction pipe and the valve.

One thought is that the container and the electronics

receiving housing part via a circumferential thread, a snap connection, a bayonet lock or a circumferential plug connection. A screw connection, a thread, is preferred. The container is placed on the housing part receiving the electronics unit

screwed on, which is associated with establishing the connection between the intake manifold and the valve. The tank, housing, intake manifold and valve are synchronized in such a way that there is inevitably a firm external connection such as the secure seat of the valve.

At its end facing away from the suction pipe, the container closes with a lid. It is expedient if the container has an inwardly projecting collar at its upper end and that a sealant is integrated in the lid on its underside facing the collar.

An O-ring is preferably considered, so that a seal in the

Moment is already realized in which the lid is connected to the container. Here too, a screw connection is intended in a preferred embodiment. The fact that the housing of the electronics housing the switch, indicator lights, connections etc. on its upper side is advantageous in that these switches, indicator lights and connections are easily accessible only after the container has been removed, but do not interfere with the rest, not to mention the design affect.

It is a matter of high effectiveness in heat transfer between

To ensure the heating chamber and the capsule inserted into it, which is made possible by the precise fit between the receptacle or parts of this receptacle on the one hand and the capsule on the other. The cone is of crucial importance with regard to the precise fit. This allows a particularly targeted heat transfer by a precisely fitting seat between the wall of the receptacle that laterally encompasses the capsule and the capsule itself. H. from the direction of the heating chamber towards the capsule. A particularly advantageous variant for such a precisely fitting seat provides that the side wall of the receptacle tapers conically in the direction of the interior of the heating chamber, the cone having an angle of approximately 5 ° to 10 °, preferably approximately 7 °. An ideal geometry is achieved if the diameter of the receptacle between the front and the back of the receptacle or the capsule increases constantly by a factor of approximately 1.1 to 1.25, preferably approximately 1.17. According to an embodiment of the invention, it is provided that the receptacle has on its outside a closing ring which extends transversely to the longitudinal axis of the housing and into which the receptacle for the capsule is integrated, i.e. the closing ring or heating chamber are arranged and designed to correspond to one another in such a way that End ring has a central opening in which the capsule sits in the receptacle. Depending on the arrangement of the container, heating chamber etc., the end ring also forms the upper or lower end of the housing or the heating chamber. In addition, the end ring has the function of acting as a stop for one

capsule-side collar when inserting the capsule into the heating chamber. The end ring does not ensure that the capsule is seated in the heating chamber lastly, in that the capsule has a collar with which it strikes against the end ring.

Thanks to a mechanism for pushing the used capsule out of its seat in the receptacle against the direction of insertion, used capsules can be pushed out of their seat in the heating chamber-side receptacle without the user coming into contact with parts of the water pipe that may be exposed to high temperatures. such

Health problems due to the high temperatures of up to 200 ° C, which heated shisha capsules can assume, are excluded, as is jamming of the capsule when it is pulled out. Any expansion processes of the capsule are also indifferent because they are particularly effective from the direction of the container from the receptacle

can be pushed out. The fact that the mechanism can be operated from outside the heating chamber aims in the same direction, namely to create a sufficient distance between the operator's hand and the heating chamber or the capsule located therein.

An advantageous embodiment of the invention provides that the suction pipe is mounted displaceably in the direction of its longitudinal axis. This is a particularly optimal solution for such a mechanism in that the suction pipe, which is present anyway, has the additional function of serving as a mechanism for removing the capsules. This is from a completely harmless distance in relation to the high temperature of the used capsules in the heating chamber. By simply pressing the suction tube, a force is exerted on the capsule against the direction in which it was inserted. As a result, the capsule inevitably disengages from its seat in the heating chamber-side receptacle. For better handling, it is contemplated that the suction pipe is displaceably supported against the force of a spring, so that the suction pipe returns to its starting position after use to remove the capsule and the play of the suction pipe during operation is limited. The invention is particularly characterized in that a

Water pipe is created with which an optimal total air supply from the capsule to the rejection of air through the mouthpiece is guaranteed. This is thanks to a special connection between the water tank and the housing of the shisha, specifically the central housing part that houses the electronics. By reliably transporting the air between the heating chamber and the central one

Housing part with electronics and water tank via the suction pipe ensures that no air can escape there, because when assembling or

Screwing the container and the central housing part together results in a particularly secure connection due to the valve positioned in the middle. For this purpose, the suction pipe opens into the container, specifically in its hollow base with a central fastening plate, which serves to mount the suction pipe in this area of the hookah.

Further details and advantages of the subject matter of the invention emerge from the following description of the associated drawing, in which a preferred exemplary embodiment is shown with the details and individual parts required for this. Show it:
