Definitions
- the invention relates to a filter element for a water pipe in the form of a bong or shisha, wherein the filter element is arranged in the flow path between an assembly for receiving the material to be smoked and a water vessel, i.e., in the case of a bong between the head and the pipe of the chillum and in the case of a shisha between the tobacco intake and the smoke tube.
- Water pipes are known in various forms, particularly as bongs or shishas.
- a bong is made of DE 10 2018 007 547 B3
- the device is known and consists of a cylindrical base, preferably made of glass, which serves as the water vessel.
- This base has a closed bottom.
- the opposite end face is open and designed as a mouthpiece for the user.
- the cylindrical base has at least one opening in its outer surface into which a chillum is inserted.
- the chillum comprises a tubular section that widens upwards to form a section with a larger diameter, the so-called head.
- the chillum is inserted into the opening in the base such that the cross-sectional area of the tubular opening is below the water level in the base.
- the smoking material is then packed into the head of the chillum.
- the user To smoke, the user first places their mouth on the open end of the base. Then, the material in the bowl is lit, and the user draws firmly on the mouthpiece. The resulting negative pressure forces a mixture of air, vapor, smoke particles, and flavorings (hereinafter referred to as "smoke”) from the bowl, through the tube-like section of the chillum, and through the water to the user's mouth.
- smoke a mixture of air, vapor, smoke particles, and flavorings
- a shisha for example, is made of DE 20 2016 003 909 U1 It is known and has a more elaborate design. It also has a water vessel, which is partially filled with water for use. The water vessel has an opening at its upper end. A flue pipe is inserted through this opening, with one end protruding from the water vessel and the other end remaining below the water level inside the vessel. The end section of the smoke tube, protruding from the water vessel, is equipped with a tobacco and charcoal holder. Furthermore, the water vessel has at least one hose connection, which is inserted into the vessel above the water level. A hose is attached to this connection, the other end of which is placed in the mouth by the user while smoking the shisha. If multiple hose connections are present, a shisha can be used by several people simultaneously.
- the tobacco chamber on the smoke tube is first filled with a specific amount of tobacco and then covered.
- the charcoal is placed on top of this cover.
- the user draws on the hose connected to the hose connector. This draw creates a vacuum in the water chamber above the water level. This vacuum draws smoke from the tobacco chamber, through the smoke tube, the water chamber, and the hose, to the user's mouth.
- bongs and shishas share a largely similar operating principle.
- a key difference, however, is that a bong is smoked without a hose, while a shisha is smoked with a hose.
- filter elements are available. Some, like those in cigarettes, are designed for single use only. However, reusable filter elements are preferred. This offers convenience because the user only needs to replace the filter element occasionally. It is also environmentally friendly because the filter element can be used multiple times, thus promoting sustainability.
- Known designs in this regard feature a base body made of glass, which has a nozzle-shaped connection on each of two opposite sides. It has a connection to components of the water pipe.
- the filter element is positioned in the flow path between the material to be smoked and the water vessel, i.e., in a bong between the bowl and the downstem, and in a shisha between the tobacco chamber and the smoke tube.
- Activated carbon is filled into the main body, absorbing a portion of the pollutants contained in the smoke.
- metal sieves are positioned in the transition areas between these connections and the spherical main body. These sieves retain the activated carbon while still ensuring good airflow for the smoke. This technical solution is considered effective in terms of its filtration performance. However, its awkward handling is a disadvantage.
- a connector for use in a hookah consisting of a cylindrical body with an inlet opening at one end for connecting to the hookah and an outlet opening at the other end for connecting to a hose.
- the inlet and outlet openings are connected by an axial bore in the cylindrical body, and a filter is inserted into a section of this bore.
- the basic idea behind this design is that not all of the flue gas passes through the filter, but rather a portion of the flue gas flows past it unfiltered. This, however, deliberately limits the filter's effectiveness.
- a filter element for a water pipe which can be arranged between a unit for holding the material to be smoked and a water vessel.
- the filter element has a hollow cylindrical base body with an open end face and a partially closed end face, wherein the base body has two sections of different diameters in the axial direction with respect to its central longitudinal axis, the second section having a smaller outer diameter and a smaller inner diameter than the first section.
- the object of the invention is to create a filter element for a water pipe that is designed as a disposable product in an environmentally sustainable manner, has good handling and enables a large number of separate, successive smoking processes.
- the partially closed end face of the hollow cylindrical base body has several parallel rib contours, between each of which a free space is arranged for airflow.
- An alternative embodiment proposes that the partially closed end face of the base body has a closed surface in which a multitude of small openings are arranged for airflow. Both embodiments ensure that, during operation of the water pipe, the user can inhale a sufficient amount of smoke through the suction motion without particles of the filter material (preferably activated carbon) entering subsequent components of the water pipe or the user's mouth.
- the hollow cylindrical base be made of a wood-based material. This allows for simple and cost-effective production, for example, on a lathe. Furthermore, environmentally sound disposal is possible after complete wear, as wood offers advantages over many other materials in terms of CO2 emissions.
- the base can also be made from other sustainable materials, such as a biodegradable plastic.
- the inventive technical solution provides a filter element for a water pipe that is designed as a disposable product, is environmentally sustainable, easy to handle, and allows for a large number of separate, successive smoking sessions. This filter element ensures a good draw during smoking.
- the filter element is a disposable product, filled only once with activated carbon as the filter material. After filling, the initially open end is sealed, for example, with a stopper, which the user removes before inserting the filter element into the hookah.
- a stopper which the user removes before inserting the filter element into the hookah.
- Current estimates suggest that such a filter element can be used for approximately 30 smoking sessions. After that, the filtering effect of the activated carbon is exhausted. Furthermore, the filter element itself will also be worn down by the heat of the smoke to such an extent that it must be disposed of.
- the filter element shown in the drawing is designed for a water pipe (not shown), but it can be used with both bongs and hookahs.
- the filter element is always positioned in the flow path between a component for holding the smoking material and a water vessel; that is, in the case of a bong, between the bowl and the downstem, and in the case of a hookah, between the tobacco chamber and the smoke tube.
- the filter element has a hollow cylindrical base body 1. From Fig. 1 It is evident that the base body 1, with respect to its central longitudinal axis MLA, has two sections 2 and 3 with different diameters in the axial direction. Furthermore, the base body 1 has an open end face 4 and a partially closed end face 5.
- the drawing shows only an exemplary embodiment of the partially closed end face 5, which here has several parallel web contours, between each of which a free space is arranged as a flow passage for the smoke.
- This partially closed end face 5 could also have a closed surface in which a multitude of small openings are arranged as flow passages for the smoke, although such an embodiment is not shown.
- the first section 2, starting from the open end face 4 has an outer diameter that remains constant along its entire length with the same size and parallel to the central longitudinal axis MLA.
- the inner diameter of this first section 2, starting from the open end face 4 initially tapers conically over a first region "a" with a diameter that decreases continuously in the axial direction.
- the contour of this conical inner surface provides good guidance for an adjacent component of the water pipe (not shown) that is to be inserted into the base body 1 of the filter element.
- the inner diameter of the first section 2 extends through a second section “b” with a consistently constant diameter parallel to the central longitudinal axis MLA.
- a circumferential contour line is formed, which is marked with a reference symbol 8.
- the first section 2 of the base body 1 transitions into the second section 3 at the end of the diameter range "b", which has a smaller outer diameter and a smaller inner diameter compared to section 2.
- the outer diameter of the The second section 3 tapers conically from the transition area between the first section 2 and the second section 3, with a diameter that decreases continuously in the axial direction.
- the contour of this conical outer surface provides good guidance for an adjacent component of the water pipe (not shown) that is slid onto the filter element.
- the inner diameter of the second section 3, starting from the transition area between the first section 2 and the second section 3 runs parallel to the central longitudinal axis (MLA) with a consistently constant diameter over the entire area "c".
- the basic body 1 is designed in the transition area between the first section 2 and the second section 3 on the outer diameter with an oblique circumferential contour 6, which runs at an acute angle to the central longitudinal axis MLA and consists of Fig. 3 as is evident.
- the base body 1 in this transition area is designed with a web-like circumferential contour 7, which runs at a right angle to the central longitudinal axis MLA and is also made of Fig. 3 as is evident.
- the interior of the base body 1 forms a chamber between the open end face 4 and the partially closed end face 5, which can be filled with filter material.
- the filter material preferably activated carbon, is not shown in the drawing. Instead, in Fig. 3 A wavy line with the reference symbol 9 is shown, which is intended to stylize a specific fill level with filter material as an example.
