Definitions
- the invention relates to a filter element for a water pipe in the form of a bong or shisha, the filter element being 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 at a shisha between the tobacco intake and the smoke pipe.
- Water pipes are known in various versions, especially in versions as bongs or shishas.
- a bong is known, for example, from DE 10 2018 007 547 B3 and consists of a cylindrical base body, which is preferably made of glass and represents the water vessel.
- This base body has a closed base area.
- the opposite end face is open and designed as a mouthpiece for the user.
- the cylindrical base body has at least one opening in its lateral surface into which a chillum is inserted.
- the chillum includes a tubular section that expands upwards to a larger diameter section, the so-called head.
- the chillum is inserted with its tubular section into the opening on the base body in such a way that the inlet cross section of the pipe opening is below the water level in the base body.
- the material selected for smoking is stuffed into the head of the chillum.
- the user To smoke, the user first places his mouth on the open-top end section of the base body. The material in the head is then ignited and the user sucks vigorously on the mouthpiece with their mouth. Due to the resulting negative pressure, a mixture of air, steam, smoke particles and aromatic substances (hereinafter referred to as “smoke”) flows from the head over the tubular section of the chillum and through the water to the user's mouth.
- smoke a mixture of air, steam, smoke particles and aromatic substances
- a shisha is known, for example, from DE 20 2016 003 909 U1 and has a more complex design. It also has a water vessel that is partially filled with water for use. The water vessel has an opening at its upper section. A smoke pipe is guided through this opening, one end section of which protrudes from the water vessel and the other end section in the water vessel below the water level is ordered. The end section of the smoke pipe protruding from the water vessel is provided with a tobacco and charcoal holder. Furthermore, the water vessel has at least one hose connection which is guided into the water vessel above the water level. A hose is arranged at the hose connection, the other end of which a user places in their mouth when smoking the shisha. If there are several hose connections, a shisha can be used by several people at the same time.
- the tobacco holder on the smoke pipe is first filled with a certain amount of tobacco and then covered.
- the coal is placed on this cover.
- the user sucks the hose contained in the hose connection with his mouth. Suction creates a negative pressure in the water vessel above the water level. Due to this suppression, smoke flows from the tobacco intake via the smoke pipe, the water vessel and the hose to the user's mouth.
- bongs and shishas have a largely similar functional principle.
- a key difference is that a bong is smoked without a hose and a shisha with a hose.
- filter elements that, like a cigarette, are only designed for one-time use. However, filter elements that can be used for several consecutive smoking processes are preferably used. This is advantageous from a convenience perspective because the user only has to insert a new filter element occasionally. At the same time, this is advantageous from an ecological point of view because the filter element is used multiple times and therefore sustainably.
- Versions known in this regard have, for example, a base body made of glass, which has a socket-shaped connection on two opposite sides connection with assemblies of the water pipe.
- the filter element is arranged in the flow path between the material to be smoked and the water vessel, ie in a bong between the bowl and the pipe of the chillum and in a shisha between the tobacco holder and the smoke pipe.
- Activated carbon is filled into the base body, which absorbs a portion of the pollutants contained in the smoke.
- metal screens are arranged in the transition areas between these connections and the spherical base body. The sieves hold back the activated carbon and still ensure a good flow for the smoke.
- This technical solution can be rated as good in terms of its filter performance.
- the disadvantage is the poor handling.
- the object of the invention is to create a filter element for a water pipe, which is designed to be ecologically sustainable as a disposable product, is easy to handle and enables a large number of separate, successive smoking processes.
- the filter element is designed as a hollow cylindrical base body with an open end face and a partially closed end face.
- the base body has two sections with different diameters in the axial direction relative to its central longitudinal axis. Starting from the open end face, a first section is designed, the outer diameter of which is constantly the same size and runs parallel to the central longitudinal axis and whose inner diameter, starting from the open end face, initially runs conically over a first area with a diameter that steadily decreases in the axial direction and then runs parallel to the central longitudinal axis over a second area with a consistently constant diameter.
- the first section of the base body merges into a second section with a smaller outer diameter and a smaller inner diameter, the outer diameter of which starts from the transition area between the first section and the second section is conical in the axial direction with a constantly decreasing diameter and whose inner diameter, starting from the transition area between the first section and the second section, runs parallel to the central longitudinal axis over the entire area with a consistently constant diameter.
- an obliquely circumferential contour is designed on the outer diameter, which runs at an acute angle to the central longitudinal axis and on endiameter, a web-like circumferential contour is designed, which runs at a right angle to the central longitudinal axis.
- the partially closed end face on the hollow cylindrical base body has a plurality of web contours running parallel to one another, between which a free installation space is arranged as a flow passage.
- the partially closed end face on the base body has a closed surface in which a large number of small openings are arranged as a flow passage.
- the hollow cylindrical base body consists of a wood material. This enables simple and cost-effective production, for example on a lathe. Furthermore, environmentally friendly disposal is possible after complete wear and tear because wood has advantages over numerous other materials in terms of CO2.
- the base body can also be made from other sustainable materials, for example from a biodegradable plastic.
- a filter element for a water pipe is created, which is designed to be ecologically sustainable as a disposable product, is easy to handle and enables a large number of separate, successive smoking processes. With this filter element, good drawing behavior is achieved when smoking.
- the filter element As a disposable product, the filter element is only filled once with activated carbon as filter material. After filling, the initially open end face is closed, for example, with a stopper, which is removed by the user before inserting the filter element into the water pipe. According to current estimates, it can be expected that such a filter element can be used for around 30 smoking sessions. After that, the filter effect of the activated carbon is exhausted. In addition, the base body is then worn to such an extent by the heat from the smoke that the filter element has to be disposed of.
- Fig. 2 shows the filter element according to Fig. 1 in a plan view of the partially closed end face.
- Fig. 3 shows a sectional view of the filter element along the line AA from Fig. 2
- the filter element shown in the drawing is designed for a water pipe, not shown, and can be used for both a bong and a shisha.
- the filter element is always arranged in the flow path between an assembly for holding the material to be smoked and a water vessel, i.e. in the case of a bong between the bowl and the pipe of the chillum and in the case of a shisha between the tobacco holder and the smoke pipe.
- the filter element has a hollow cylindrical base body 1. From Fig. 1 it can be seen that the base body 1 has two sections 2 and 3 with different diameters in the axial direction relative to its central longitudinal axis MLA. Furthermore, the base body 1 has an open end face 4 and a partially closed end face 5. The drawing only shows an exemplary embodiment of the partially closed end face 5, which here has several web contours running parallel to one another, between which a free installation space is arranged as a flow passage for the smoke. Likewise, this partially closed end face 5 can also have a closed surface in which a large number of small openings are arranged as a flow passage 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 which is constant over its entire length and is of the same size throughout and parallel to the central longitudinal axis MLA.
- the inner diameter of this first section 2, starting from the open end face 4 initially runs conically over a first area “a” with a diameter that steadily decreases 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 runs over a second area “b” with a constant diameter throughout, parallel to the central longitudinal axis MLA.
- a circumferential contour line that is marked with a reference number 8.
- first section 2 of the base body 1 merges at the end of the diameter range “b” into the second section 3, which has a smaller outer diameter and a smaller inner diameter compared to section 2.
- the outer diameter of the second section 3 runs conically, starting from the transition region between the first section 2 and the second section 3, with a diameter that steadily decreases in the axial direction.
- this conical outer surface provides good guidance for an adjacent component of the water pipe (not shown) that is to be pushed 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 over the entire area “c” with a consistently constant diameter parallel to the central longitudinal axis MLA.
- the base body 1 is designed in the transition area between the first section 2 and the second section 3 on the outer diameter with an obliquely circumferential contour 6, which runs at an acute angle to the central longitudinal axis MLA and can be seen from FIG. 3.
- 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 can also be seen in FIG. 3.
- the interior of the base body 1 forms a chamber that can be filled with filter material between the open end face 4 and the partially closed end face 5.
- the filter material preferably activated carbon, is not shown in the drawing. Instead, a wavy line with the reference number 9 is shown in FIG. 3, which is intended to stylize a specific filling level with filter material by way of example.
