Abstract
A water pipe (1) comprises a housing (2) into which a receptacle (3), which has at least one suction connection (6) and which can be filled with a liquid medium, and a heating chamber (4), which is connected to the receptacle via a suction hose (6), are integrated. The heating chamber (4) comprises a receiving portion (5) for a capsule (10) which holds a smoking medium. The spent capsule (10) can be ejected from its seat in the receiving portion (5) in the direction of the receptacle (3) by means of a mechanism.

Description
[0025] Further details and advantages of the subject matter of the invention arise from the following description of the associated Drawing, in which a preferred embodiment example is illustrated together with the details and individual parts necessary for this purpose. There are shown:
[0026] FIG. 1 an elevation view of a water pipe,
[0027] FIG. 2 a plan view of a heating chamber with suction hose,
[0028] FIG. 3 a perspective illustration relating to FIG. 2,
[0029] FIG. 4 a longitudinal cross-section through the heating chamber and suction hose,
[0030] FIG. 5 a detail of FIG. 4,
[0031] FIG. 6 a plan view of a receiving portion,
[0032] FIG. 7 a receiving portion with a capsule inserted,
[0033] FIG. 8 a detail of FIG. 9,
[0034] FIG. 9 closure ring, receiving portion and capsule, and
[0035] FIG. 10 a cross-section through the aperture of the suction hose.
[0036] FIG. 1 shows a water pipe 1, also called a shisha or hookah. The construction of the water pipe 1 with its elongated housing 2 and with its modular design is particularly compact. The receptacle 3 is closed at the top by the cover 21. The integral end of a suction hose 22 is connected to the connection piece 23 as part of the cover 21, and is fitted with an interchangeable mouthpiece 24 at the other end. The connection of several hoses is conceivable. The water level for the water held in the receptacle 3 is indicated by 25, since only partial filling of the receptacle 3 is entirely expedient. The on, off and standby switch to operate the shisha 1 is designated by 26. Two capsules with perforations 27 and holding smoking medium are indicated by 10, 10′. The air inlet in the form of several air slots carries the reference marking 28.
[0037] Moreover, FIGS. 2 and 3 show a plan view of the heating chamber 4 with suction pipe 6 that is carried in the sleeve-like guide bolt 15.
[0038] FIG. 4 represents a cross-section along A-A in FIG. 2. The reference mark 6 designates the 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 in the direction of the arrow 40 by hand or by a controller. The suction hose 6 possesses two pipe sections 11 and 12 of different diameters. In this respect, section 12 of the suction hose 6 facing towards the heating chamber 4 has a diameter smaller than that of section 11 pointing towards the receptacle, not shown here, so that a shoulder or end- stop 13 acting against spring 7 forms when the suction hose 6 is moved. Thus the second pipe section 12 is surrounded by the compression spring 7 at its end 16 pointing towards the first pipe section 11, and the spring shaft 18 is integrated into the wall 17 of the heating chamber 4 pointing towards the receptacle.
[0039] The fact that the front end 19 of the second pipe section 12 extends into the heating chamber 4 is easily recognisable.
[0040] FIG. 5 is an enlargement showing the detail from FIG. 4 with a view of the suction hose 6 and inner tube 14. The latter has a shoulder 13 formed by the inner tube 14 having a diameter at its front end smaller than at its back end, thus forming the spring shaft 18. The fact that the spring is accommodated in the wall 17, which then in turn represents the outer closure of the spring shaft 18, is also easily recognisable in FIG. 5.
[0041] FIGS. 6 and 7 then show the consequence of this. FIG. 2 shows a receiving portion 5 for a capsule 10. At the same time, the exactly fitting seat between the side wall 30 of the receiving portion 5 (external) and the wall 31 of capsule 10 is readily recognisable. 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 a of approx. 7°. At its inner side, the receiving portion 5 comprises an end wall 34 having an opening and extending essentially at right angles to the longitudinal axis 8 of housing 2, and thus also of receiving portion 5. A free space 36 can remain between the end wall 34 of receiving portion 5 and the end wall 35 of the capsule 10. The collar 37, which in turn runs at right angles to the longitudinal axis 8 at the outer side of receiving portion 5, is also easily recognisable. The closure ring 38 is integrated into the housing.
[0042] FIG. 7, with reference to FIG. 6, shows the cross-section A-A of the latter, and on the other hand, from the outside to the inside, the components closure ring 38, collar 37, wall 30, 31 (cone), end wall 34 and opening 39.
[0043] FIG. 8 shows the detail encircled in FIG. 9, in the form of the integration of the receiving portion into the closure ring 41. The closure ring 41 is connected to the collar 42 on the receiving side. At the same time, capsule 10 lies with its collar 43 in the receiving portion 5, and does so particularly tightly due to the uniform cones/tapers of approx. 7°.
[0044] It must also be mentioned that, in order to fit to the closure ring 41, the capsule 10 has, between collar 43 and its actual wall 44, a section 45 in which the wall of capsule 10 runs exactly parallel to the longitudinal axis 46.
[0045] As a supplement to this, FIG. 10 shows a cross-section through water pipe 1. In the centre is the housing portion, and below it is the heating chamber with the receiving portion for a capsule and the demountable base plate. When these two components are combined together, a thread automatically ensures the positioning of the centrally positioned valve 48, which sits in the base 54 of the receptacle and extends some distance into the receptacle interior 53. FIG. 10 illustrates the massive, multi-layered construction of the base 54 of the receptacle 3. The opening 57 of the suction hose 6 is secured by three seals in the form of O-rings 49, 50, 51. Valve 48 and suction hose 6 lie in a common longitudinal axis 52. A hollow cavity, integrated into the base 54 and indicated by 55, accommodates a central fastening plate 56 into which the suction hose 6 then actually opens.
