Description

Valve system for water pipe

Technical Field

The utility model relates to the field of water tobacco pipes, in particular to a valve system for a water tobacco pipe.

Background

Hookah pipes, also called water pipes or water pipes, usually comprise a water container (the so-called bowl) and a closing head fastened to the water container. A flue gas pipe is fastened to the closing head, at the upper end of which a flue gas head is arranged, on which the tobacco is burnt or vaporized together with the hot char. The flue gas pipe extends into the water container through the closing head and opens with its lower end into the water container below the horizontal plane. The lower end of the flue gas pipe may be configured as a diffuser to reduce the noise of the air bubbles. Furthermore, a connection possibility for at least one fume hose is provided on the closure head, which opens into an air space provided in the water container between the head and the liquid surface via a corresponding recess. When a user sucks in the tobacco smoke through the smoke hose, a negative pressure is generated in the air space provided in the water container, the tobacco smoke is sucked in through the smoke pipe by means of the negative pressure, and the tobacco smoke is cleaned, cooled and humidified when passing through the liquid.

It is important here that the closure completely seals the water container, since otherwise secondary air would be sucked in and the water pipe would no longer "suck up" correctly.

Known closures are constructed, for example, in the manner of screw closures or plug closures and have connection openings for a plurality of smoke hoses.

The connection opening for the flue gas hose opens in a known manner into the water container indirectly or directly via the recess. In order to prevent undesired secondary air from being sucked in through unused connection openings, in particular when a plurality of connection openings are arranged, one for each flue gas hose, valve devices in the form of check valves can be provided in each of the recess or recesses. The valve device may have a gravity-loaded and/or spring-loaded valve body which can be brought into sealing contact with a valve seat detachably fastened at the end face in or on the recess. By releasing the valve seat, the valve device, or at least the valve body, can be removed, installed or replaced as required.

In order to be able to blow fresh air into the air space of the water container, in particular during use of the water pipe, by means of one of the flue gas hoses, for example in order to reduce the flue gas temperature, the associated non-return valve of the flue gas connection is usually removed or bypassed by a valve device. A disadvantage is that no fresh air reaches the flue gas pipe when blowing fresh air into the air space of the water container, since the flue gas pipe opens with its lower end into the water container below the water level and seals off as a siphon. When fresh air is blown in, the air pressure in the water reservoir increases and the water column rises 10mm to 50mm in the flue gas column. Only air displaced by the water jet escapes from the flue gas duct through the tobacco head. Complete exchange with fresh air cannot be achieved. The tobacco in the tobacco head is not significantly cooled by the slight amount of air exchange. A substantial reduction in the flue gas temperature is not achieved by repeatedly blowing in fresh air.

In the first recess 52, valve devices are provided which each have a valve body in the form of a first check valve ball 53 and a first valve seat 54. The first recess 52 is open toward the lower end of the second closing part 02 and opens into the air space 07 and toward the upper end of the second closing part 02 and opens into the ambient air.

The exemplary embodiment shown in fig. 4 corresponds to the exemplary embodiment according to fig. 3, with the exception of the valve unlocking mechanism 97. The second recess 35 is arranged in the upper section 30 of the second closing element 02. In the second recess 35, valve devices are provided, each having a second valve body 36 and a second valve seat 37.

The second recess 35 is open toward the lower end of the second closing part 02 and opens into the air space 07 and in the second closing part 02 toward the through-opening 22 and into the upper flue gas duct 23. The second valve body 36 is loaded by its own weight and/or by a settable spring onto the second valve seat 37. The second valve body 36 and the second valve seat 37 are replaceable. The valve body mass and the valve seat area determine the response pressure and flow of the valve mechanism 96. The cross-section of the second recess 35 may be adjustable.

In the upper section 30 of the second closing element 02, a third valve means 95 is arranged, the third valve body 50 of which can be in sealing contact with the third valve seat 51. If an overpressure is generated by blowing air into the not shown flue gas hose via the flue gas hose connection 19, this overpressure acts on the second valve body 36 and the first valve body 53. By selecting the valve body mass and the valve seat area, the opening time point of the valve can be determined. The user can operate the valves individually or collectively by the amount of air blown in. The first recess 52 can be closed manually by operating the third valve mechanism 95.

The connection with the second recess 35 remains closed. If the blow-in quantity increases, the overpressure rises and opens the first check valve ball 53 into the second switching position. In this second switching position, the connection to the through-opening 22 and to the upper flue gas duct 23 is opened. In order to prevent the inflow of ambient air, a further fourth valve body 56 and a further fourth valve seat 57 can be provided in the first recess 52.

The fifth valve body 38 is floatable.

If an overpressure is generated by blowing air into the not shown flue gas hose via the flue gas hose connection 19, this overpressure acts on the second valve body 36 and opens the connection to the second recess 35 and to the lower flue gas pipe 24.

The overpressure causes a water column to rise in the lower flue pipe 24. The rising water column lifts the fifth valve body 38 and places it in sealing abutment with the fifth valve seat 39. Further elevation of the water column in the lower flue gas duct 24 is suppressed by the sealing action.
