Description

Hookah

Technical Field

The technical field of the invention is the field of hookah, in particular portable hookah.

Background

Hookah, also called a hookah pipe or hookah, is a special pipe in which the fumes produced by the combustion of tobacco are conveyed due to a pipe immersed in the water contained in a water tank (hereinafter, referred to as the immersed pipe). The fumes then enter the water contained in the tank in the form of bubbles, which break at the surface of the water. Thus, after having filtered the smoke through its passage in the water, the user inhales the smoke through the flexible suction hose.

Hookah cartridges are usually bulky and heavy, and therefore are intended to keep it immobile when it is used, for example on a table. In order to allow the user to position himself away from the cartridge and leave him with some freedom of movement, the length of the suction hose is typically about one meter. As regards the diameter of the hose, it is generally comprised between 1 and 3 cm, to enable the easy inhalation of the fumes.

In the field of hookahs, new demands have arisen in recent years due to the increase in movement and travel of professionals or private persons. Indeed, as noted above, conventional hookahs are typically bulky. Furthermore, it has a generally complex overall shape, with several elements (bowl, cup, fume duct, suction hose) protruding outside the tank, which may hit obstacles or come loose from the assembly during transport. The suction hose in particular makes such a transport inconvenient because of its considerable length and diameter.

Disclosure of Invention

In order to at least partially solve the above problems, the present invention proposes a portable hookah, comprising:

a body having a bottom and one or more side walls, which together define an interior volume of the hookah, and an opening opposite the bottom,

-a removable cap engaged in said opening to close the body, the cap being provided with a bowl for the combustion of the tobacco and a dip tube extending towards the bottom in the internal volume of the hookah, the dip tube communicating the bowl and the internal volume of the hookah, and

a suction opening to which a detachable suction hose can be connected and which communicates the outside of the hookah with its inner volume,

the hookah further comprises a wrapping element comprising a cylindrical tube externally provided with ribs wound several times around the cylindrical tube by forming spirals suitable for guiding the flexible suction hose when winding it on the cylindrical tube, the wrapping element being dimensioned such that it can be accommodated in the inner volume of the hookah, the wrapping element then surrounding the immersion tube.

Due to the wrapping, a cumbersome suction hose can be easily stored inside the hookah for storage or transport of the hookah. The wrapping further prevents the hose from flattening and imposes a moderate and constant radius of curvature.

When the hose is wound on the winding, when the winding is placed in the annular housing of said annular container, and when the cap closes the body of the hookah, all the elements necessary for the operation of the hookah are contained inside the hookah, which makes it easy to handle, transport and store. This particular arrangement may in particular provide a smooth appearance without protrusions or embossments on the hookah in which the suction hose is accommodated, for example the exterior shape of the canister is cylindrical, which further facilitates its handling and its storage.

Preferably, the wrapping constitutes a detachable part which is not connected to other elements of the hookah and which can be freely detached from the hookah. This makes the wrapping easier to handle and thereby facilitates unwinding and wrapping of the hose on the wrapping, particularly compared to arrangements in which the wrapping may be integral with the cap or dip tube.

Further, it may be provided that the main body includes:

-a reservoir for containing water, having a bottom forming a bottom of the body and at least one side wall connected to the bottom and extending from the bottom to an opening of the reservoir, and

an annular container comprising an annular outer wall and an annular inner wall, connected to each other at their lower ends by a return wall, to define between each other an annular casing which is open at its upper end and is suitable for housing a winding element inside the annular casing,

the annular container is fastened to the reservoir at the side of said return wall by forming a sealing engagement with the reservoir all along the opening of the reservoir.

The particular configuration defined in the above paragraph makes it possible to divide the internal volume of the cartridge into two distinct portions hermetically separated from each other, one intended to receive the wrapping (with or without the hose) and the other intended to receive the filtered water in the reservoir. Thus, contact between the filtered water and the hose or wrapping is avoided. This arrangement enables in particular to store the wrapping in the body of the hookah cartridge (which avoids losing it or dirtying it) when the cartridge is in use, and therefore when there is water in the reservoir, without the need to place the wrapping in contact with the water contained in the reservoir. Furthermore, this arrangement prevents the hose from being soiled or wetted when the cartridge is in the transport configuration (the hose is wound on the winding and housed in the annular container in question). This is interesting because the hose must be kept as clean and mould-free as possible. Furthermore, this configuration makes it possible to limit the volume of the reservoir (since the hose is housed outside the reservoir itself), which simplifies the potential cleaning of the reservoir and avoids excessive filling with water.

The reservoir and the container may be fastened to each other by reversible fastening means, for example by a pitch system, or by a force snap fitting, so that the container on the reservoir can be easily disassembled and reassembled to enable easier emptying and cleaning of the reservoir after use.

The suction port may be made in the cap (rather than, for example, in the sidewall of the body). In this case, the inner volume of the hookah can be organized and arranged very freely.

An annular chamber surrounding the dip tube may also be provided in the cap, said chamber opening axially on the side of the internal volume of the hookah, opposite the bowl, (in other words, it is open on the lower side and open into the internal volume of the cartridge), said chamber further opening transversely to the outside of the hookah, through said suction opening provided transversely to the cap.

Furthermore, the cap may be shaped to fit into the upper opening of the annular housing defined by the aforementioned annular container, to hermetically close the housing and the internal volume of the cartridge when the cap is in place on the body of the cartridge.

The winding may be provided at the lower end of the helix formed by the ribs with a first fastening element in or on which the neck of the suction hose may be force-engaged. This makes it possible to fix one end of the hose to the winding member before winding the hose. For example, the fastening element may be produced in the form of a cylindrical stud of diameter slightly greater than the inner diameter of the hose, the axis of the stud being orthogonal-radial with respect to the axis of the wrapping (that is to say with respect to the axis of the cylindrical tube of the wrapping). The winding can also be provided at the upper end of the helix formed by the ribs with a second fastening element in or on which the suction hose can be force-engaged. This ultimately makes it possible to integrate the hose and the wrapping once the hose is wrapped around it. For example, the second fastening element may be made in the form of a pair of plates parallel to each other and facing each other, each plate being an extension of a portion of the helical rib, extending radially outwards with respect to the cylindrical tube of the wrapping. The distance separating the two plates in question may be equal to or slightly less than the outer diameter of the hose.

The hookah may further comprise:

-a discharge pipe interconnecting the inner volume of the hookah with the outside of the hookah and opening out of the hookah through a discharge opening different from the suction opening, and

-configuring the check valve such that:

-allowing air and smoke to pass through the discharge pipe when the pressure in the inner volume of the hookah is greater than the pressure outside the hookah, and, so that

-sealing the discharge tube when the pressure in the inner volume of the hookah is lower than the pressure outside the hookah.

For example, the drain tube and check valve may be disposed in the cap.

The invention will be better understood upon reading the following description and examining the appended drawings.

Detailed Description

Fig. 1 shows a portable hookah 10 in a transport configuration. In this figure can be seen:

a body 1 of the cartridge, which here comprises a cylindrical reservoir 3, on which an annular container 4 is fastened,

a removable cap 2, which encloses the body 1, the cap 2 being provided with a bowl 6 (see fig. 2) for the combustion of tobacco and with a dip tube 51, a suction opening 52 being formed in the cap to communicate between the outside and the internal volume of the hookah, an

A grated cover 7 mounted to the cap 2.

The lid 7 is useful, in particular, when a hookah is used. The grill enables the passage of the air necessary for the operation of the cartridge, while protecting the bowl, thus avoiding the user from burning himself on the charcoal placed on the bowl, in order to enable the combustion of the tobacco. With the lid, for example, the height of the hookah measures between 15 cm and 30 cm.

Fig. 2 shows a hookah 10 having the same configuration as in fig. 1, but without the lid 7.

The internal layout of the cartridge is shown in fig. 3, and fig. 3 is a schematic cross-sectional view of the cartridge in a use configuration.

In the particular embodiment described herein, the reservoir 3 is cylindrical. It comprises a bottom 30 and a cylindrical side wall 31 connected to the bottom 30 and extending to a circular opening 32 of the reservoir. It is filled with water and is marked with the reference number 33 in the figure. However, in the alternative, the reservoir may have a shape other than a cylinder; for example, it may be in the shape of a flat-bottomed flask with an upper circular opening.

Here, the annular container 4 is cylindrical with the same outer diameter as the reservoir 3. The lid 7 is also cylindrical, having the same outer diameter as the reservoir 3 and the cap 2. A cartridge is thus obtained having a smooth, uniform outer surface, and no projecting parts, which facilitates transport, handling and storage of the cartridge.

The annular container 4 forming the upper part of the body of the hookah comprises a cylindrical outer wall 41 and a cylindrical inner wall 44, which cylindrical outer wall 41 and inner wall 44 are connected to each other at their lower ends by a return wall 43 to define between each other an annular housing L open at its upper end. The annular housing L thus forms an annular groove with a U-shaped cross section, open at the top and at the bottom formed by the return wall 43. The annular container 4 extends around the axis of the hookah (that is, around the axis on which the body of the hookah is centrally located, which axis corresponds to the axis of the cylindrical walls 41 and 44). Thus, the annular container 4 leaves a free central volume, here substantially cylindrical, which lies on the axis of the cartridge (centered on this axis) and forms a free passage from top to bottom which is passing through the annular container 4. Here, the return wall 43 extends orthogonally with respect to the axis of the barrel.

The annular container 4 is fastened to the reservoir 3 such that the opening 32 of the reservoir matches the circular ridge at the boundary between the cylindrical outer wall 41 and the return wall 43. The engagement between the annular container 4 and the reservoir 3 is achieved, for example, by screwing, by means of complementary threads present on the reservoir and on the lower end of the cylindrical outer wall 41, respectively. The cylindrical outer wall 41 may extend slightly beyond the return wall 43 (which is flat here) to form a rounded edge, the interior of which is threaded. In this case, the annular container 4 comprises in its lower part a portion having an internal thread pitch complementary to the external thread pitch present on the reservoir 3.

The bottom 30 of the container 3, its side wall 31 and the cylindrical outer wall 41 of the annular container together define the internal volume V of the cartridge (hence, here the cylindrical volume, and extending from the bottom 30 to the upper open end of the annular container the opening (here circular) of the body 1 is here constituted by the free upper end 42 of the cylindrical outer wall 41.

The cap 2 has the general shape of a thick disc made of rubber or silicone, which closes the body 1 of the tube. A bowl 6 for the combustion of tobacco is located at the top of the cap 2. The cap is further provided with a dip tube 51, the dip tube 51 extending into the inner volume V of the hookah towards the bottom 30. The dip tube passes through the cap 2 to connect the bowl 6 so that the bowl 6 communicates with the inner volume V of the hookah. The dip tube 51 extends from the tube cap 2 down into the reservoir 3, through an empty passage through the annular container 4 from top to bottom, along the axis of the cartridge, and ultimately into the filtered water 33.

The cap 2 also comprises, on the lower side, a thick annular lip 54 which engages in the (upper) opening of the annular container 4, which makes it possible to hermetically close the annular housing L, as well as the entire internal volume V of the hookah (except for the inlet constituted by the dip tube, the outlet constituted by the suction mouth 52 and the outlet constituted by the discharge mouth 23, see fig. 3).

An annular chamber 53 is provided in the cap 2 around the dip tube 51. The chamber is axially open on the side of the inner volume V of the hookah, opposite the bowl 6. In other words, the annular chamber 53 forms a kind of cavity or annular groove opening on the lower side on the side of the inner volume V of the cartridge. The annular chamber 53 opens more specifically into the internal volume V in the empty space left between the dipleg 51 and the annular container 4. Thus, its opening is located between the annular lip 54 and the dipleg 51. Furthermore, the chamber is laterally open to the outside Ext of the hookah through said suction opening 52 provided laterally on the cap 2, thereby communicating the internal volume V of the hookah with the outside Ext of the hookah. In this case, the annular chamber 53 is interconnected with the suction mouth 52 by a duct 21, which duct 21 extends through the cap 2 in a radial direction with respect to the axis of the hookah.

However, in the alternative, by arranging in the cap a passage having a different geometry from the annular chamber described above, it is possible to place the internal volume of the cartridge in communication with the outside via a suction opening formed transversely in the cap.

The hookah 10 further comprises a discharge pipe 26, which discharge pipe 26 interconnects the inner volume V of the hookah with the outside Ext of the hookah and is open to the outside of the hookah through a discharge opening 23 different from the suction opening 52 (fig. 3).

The hookah further comprises a check valve 27 configured such that:

when the pressure in the internal volume V of the hookah is greater than the pressure Ext of the outside of the hookah, air and smoke are allowed to pass through the discharge pipe 26, and, so that

Sealing the discharge tube 26 when the pressure in the internal volume V of the hookah is lower than the pressure Ext outside the hookah.

In the embodiment shown in the figures, a discharge tube 26 and a check valve 27 are arranged in the cap 2.

The discharge tube 26 and the valve 27 allow the user to easily discharge the fumes contained in the internal volume V of the cartridge. To do this, the user exhales into the suction hose 8 (rather than inhaling from it), which has the effect of increasing the pressure within the volume and thereby opening the valve 27 and then expelling the smoke to the exterior of the canister.

When the user stops exhaling into the suction hose 8, the valve 27 is closed, thereby sealing the discharge tube 26. In the operating mode (as described in the introduction) corresponding to the normal operating mode of a hookah, when the user next inhales from the suction hose 8, air passes only through the bowl 6 (and then through the dip tube), with tobacco smoke entering the canister.

Here, the discharge port 23 is transversely provided on the cap 2. The exhaust pipe 26 interconnects the aforementioned annular chamber 53 to the discharge opening. The discharge pipe here extends radially with respect to the axis of the drum.

The valve 27 is arranged between the discharge pipe 23 and the annular chamber 53. It comprises

-a sphere 22 of a shape such as a sphere,

a valve seat 24 comprising a conical abutment surface, open at the lower side to open into the annular chamber 53, an

A space 25 opposite the seat 24, in which the ball can be at least partially housed to clear the passage between the seat and the drain pipe 26.

When the pressure within the internal volume of the cartridge is lower than the pressure outside the hookah, the ball bears against the conical surface of the valve seat 24, thereby sealing the discharge tube 26. Conversely, when the pressure within the internal volume of the canister is greater than the pressure outside the hookah, the ball lifts from the valve seat and is (at least partially) contained in the void 25, thereby allowing smoke to exit the canister through the exhaust port 23.

In this arrangement, when the pressure inside the cartridge is the same as the pressure outside the cartridge, the valve 27 is closed, since the ball 22 then rests on the seat 24 under the effect of its weight. However, the valve can be equipped with an optional spring, working in compression, on the one hand against the ball 22 and on the other hand against the bottom of the interspace 25. The spring then presses the ball 22 against the seat 24, provided that the pressure within the internal volume is not slightly greater than the pressure outside the cartridge. In this case, the valve allows air and smoke to pass through the discharge pipe 26, not only if the pressure in the internal volume is greater than the pressure outside the hookah, but also if the pressure in the internal volume exceeds the pressure outside the hookah by a given amount (depending on the stiffness of the spring).

In other embodiments, the discharge pipe may be arranged differently than what has been described above, and the check valve may be made in another way (e.g. by a cone instead of a sphere).

The removable cap 2, unlike the cover 7, has several functions. It serves as a container for a ceramic bowl 6 which is sealingly received inside. The bowl 6 is the part that receives tobacco smoked in molasses form in a hookah. Thanks to its discharge duct 26 and check valve 27, cap 2 can also discharge the fumes contained in the internal volume V of the cartridge when the user considers them too rich. The cap 2 can also diffuse the smoke to the suction hose 8, or, in other words, deliver the smoke to the opening of the suction hose. Finally, the lid 7 may be mounted to the remainder of the cartridge. The cap 2, which interconnects a large number of elements of the cartridge, therefore plays an important role in its structure and during the assembly and disassembly of the cartridge (that is to say when switching from the transport configuration to the use configuration). During the assembly/disassembly of the cartridge, as shown here, the use of this cap 2 made of rubber or silicone enables easy assembly of these different elements, while providing on the same single component the different sealing joints (bowl-dip tube joint, closure of the internal volume, and joint with the suction hose) necessary for its operation.

The suction hose 8 is connected to the rest of the cartridge via a suction opening 52, for example, when the suction hose 8 is inserted therein. The flexible suction hose 8 has a length comprised between 0.5 and 1.5 meters and an outer diameter comprised between 1 and 3 centimeters, for example. It may be made, for example, of food grade silicone. The first end of the hose 8 may be provided with a hollow shaft 11 placed in the mouth to inhale smoke. To use the cartridge, the shaft 11 is force-engaged in the first neck 81 of the hose, i.e. in the first end opening of the hose. The shaft is stored in the cartridge when the cartridge is in the transport configuration. For this purpose, a shaft 11 with an inner diameter slightly larger than the outer diameter of the immersion tube 51 is engaged on the immersion tube (as it is screwed onto the immersion tube). The second end 82 of the hose is here provided with a connector 12, for example made of rigid plastic. The hollow connector 12 is force fitted onto the suction hose 8 until the flange of the connector abuts against the end of the hose. A portion of the tubular connector 12 is then exposed from the hose. The tubular member is engaged in the suction port 52 to connect the hose 8 to the suction port 52. The rigid connector 12 is capable of connecting a hose and a cap, both made of flexible material, in a convenient and sealed manner. The connector 12 is shorter than the shaft 11 and can be left in place on the hose when it is wound on the winding member 9 to be stored in the cartridge.

The hookah 10 also includes a generally cylindrical wrap 9 (shown in more detail in figures 6-11) around which the flexible hose 8 may be wrapped.

In the transport configuration, for example in the case of fig. 1, the suction hose 8 is wound around the winding piece 9, and the winding piece 9 (equipped with a hose) is housed in the above-mentioned annular housing L.

In the use configuration, the suction hose 8 is no longer wound on the winding 9. The winding 9 (which is no longer equipped with a hose) can here again be accommodated in the annular housing L (this avoids losing it or soiling it).

The winding member 9, for example made by moulding of a plastic material, comprises a cylindrical tube 91, the cylindrical tube 91 being externally provided with a rib 92, which rib 92 is wound around the cylindrical tube 91 several times by forming a helix, so as to be suitable for guiding the flexible suction hose 8 when the suction hose 8 is wound around the cylindrical tube 91. The pitch of the helix in question is therefore close to the outer diameter of the hose 8.

The wrapping 9 is dimensioned to be able to be housed in the internal volume V of the hookah, even more specifically in the annular housing L of the annular container 4, including when the suction hose 8 is wrapped on the wrapping 9. Therefore, the sum of the outer diameter D9 of the cylindrical tube 91 of the winding member and twice the outer diameter D8 of the suction hose is smaller than the inner diameter of the main body 1 of the cartridge. Here, the sum is more specifically smaller than the inner diameter D41 of the cylindrical outer wall 41: d9+2.D8 were constructed as D41. Also, the inner diameter D9' of the cylindrical tube 91 is larger than the outer diameter D51 of the dip tube. Here, the inner diameter D9' of the cylindrical tube 91 is more specifically greater than the outer diameter D44 of the cylindrical inner wall 44 of the annular container: d9' > D44> D51.

The winding 9 is provided at the lower end 92' of the spiral formed by the rib 92 in question with a first fastening element in or on which the neck 81 of the suction hose can be force-engaged. The first fastening element is realized here in the form of a cylindrical stud 93, the diameter of which is slightly larger than the inner diameter of the suction hose 8. The axis of the stud 93 is orthogonal-radial with respect to the axis of the wrapping (that is, with respect to the axis of the cylindrical tube 91). The stud 93 is positioned lower than the lower end 92' of the helix. It is supported by a plate extending perpendicularly with respect to the outer surface of the tube 91. The stud 93 makes it possible to fasten the first end 81 of the suction hose 8 to the wrapping 9 before the hose is wrapped.

The winding 9 is also provided at the upper end 92 "of the spiral formed by the ribs 92 with a second fastening element in or on which the suction hose 8 can be force-engaged. This ultimately enables the hose 8 and the wrapping 9 to be integrated (i.e. connected to each other without relative movement) once the hose is wrapped around the wrapping 9. The second fastening member here comprises a pair of

plates

94, 95 shaped to hold the other end 82 of the hose firmly between them once the hose is wound. The two

plates

94, 95 are parallel to each other and located facing each other. Each plate abuts as it were against a portion of the spiral rib 92 while extending the rib radially outward. The two

plates

94, 95 are spaced apart a distance equal to or slightly less than the outer diameter D8 of the suction hose 8. Each

plate

94, 95 extends from the cylindrical outer surface of the tube 91 by a distance, here greater than or equal to half the outer diameter D8 of the suction hose 8, to effectively retain the hose 8 between the plates (this distance corresponds to the width of the plates, being equal to the extension of the plates in the radial direction with respect to the axis of the tube 91). The width of the rib 92 (that is to say its extension in a radial direction with respect to the axis of the tube 91) is much smaller than the width of one or other of the plates 94, 95: the rib serves as a guide for the winding of the hose, but it does not enable the hose 8 and the winding member 9 to be integrated.

In the cylindrical tube 91 of the wrapping, a gap 96 is further made between the two

plates

94, 95. The void 96 forms an elongate hole which extends along a portion of the helical path defined by the rib 92 (the path followed by the hose when it is wound on the winding member). The aperture extends over the surface of the tube 91 for a length substantially equal to (here equal to) the length of the

plates

94, 95, here equal to about half the circumference of the tube. When the hose is wound around the winding member, a portion of the hose 8 (at the side of its second end 82) abuts the gap 93 and is wound slightly beyond it. This makes it possible to slightly push the hose toward the inside of the tube 91, thereby improving the retention of the

plates

94 and 95.

As already mentioned, on this second end 82, the hose 8 can be fastened to the wrapping between these two plates, while remaining equipped with the connector 12.

The particular configuration of the second fastening element just described makes it possible to fasten the hose 8 to the winding even if the hose has a slightly varying length. In practice, when the hose is wound it runs from the stud 93, but depending on the exact length of the hose it may stop at different levels along the helical path described above (however, once the hose is wound, as long as the second end ends up between the two plates 94 and 95). This arrangement of the second fastening element, in which the second end 82 is pushed between the plates once the hose is wound around the tube 91, further enables the second end of the hose to be fastened to the winding while maintaining a slight tension in the hose to keep it correctly against the tube 91 all the way along the hose.

The assembly of the cartridge can be carried out as explained below, which makes it possible to switch from its transport (and storage) configuration to its use configuration.

First, the lid 7 is removed from the cap 2, and the cap is removed from the body 1 of the hookah. Next, the winding member 9 is taken out of the annular chamber L, and the suction hose 8 is unwound. The shaft 11, initially engaged on the dipleg 51, is removed therefrom and then fastened to the first end 81 of the hose. Next, the reservoir 3 is filled with water (while optionally unscrewing the reservoir for this purpose and then putting it back on screwing). The winding (without the hose 8) is then preferably placed back into the annular chamber L. The cap 2 is then placed back onto the body 1 of the hookah to close it. The second end 82 of the hose 8 is then connected to the suction opening 52 due to the connector 12. Tobacco product, then hot charcoal, is then placed in the bowl 6. Finally, the cover 7 is replaced onto the cap 2.
