    The present invention relates to a smoke generator for hookah.
    As illustrated in FIG. 1 and in a known manner, a hookah 10, also called chicha, shisha, nurgil, ghelyan, arguileh, houka, hookah, chilam, gelyoun, hubby-bubbly, qalyan or water pipe, is a pipe allowing to smoking a smoking mixture. The mixture, sometimes referred to as tabamel, can include tobacco, molasses, fruit essences, smoking gel, smoking stones or other components. The hookah 10 includes, at its head 15, a smoke generator 1 capable of producing smoke. This device 1 is disposed above a vertical chimney 11 ensuring the transport of the smoke, up to a vase 12 containing a liquid, typically water, which may include perfumes, dyes, fruits, ice cubes , etc. Passing through the liquid, the smoke is advantageously cooled and filtered. Then the smoke borrows at least one flexible pipe 13 to a nozzle 14 used by the smoker to inhale the smoke.
    The hookah is used, since its invention more than 450 years ago in India according to a first version and there is more than 700 years in Africa according to another version, traditionally in Africa, in South Asia and in the Middle East. Its use extends today to much wider horizons. The number of hookah smokers is estimated to be over 100 million worldwide.
    As illustrated by the block diagram in FIG. 2, a smoke generator 1 produces smoke by combustion of the mixture M, previously arranged in a receptacle provided for this purpose in the smoke generator 1. The combustion is produced by a heating element H received in the smoke generator 1 and placed above the mixture M. The heating element H is traditionally a combustible element, such as coal. In order to avoid too rapid combustion, the contact between the heating element H and the mixture M generally takes place through a heat shield S. The heating element H communicates its heat to the mixture M, on the one hand by contact and on the other hand by means of a first circulation of fluid Cl between the heating element H and the mixture M. The term fluid in the present, mainly air, can be charged with smoke from the combustion of the heating element H or in smoke from the mixture M.
    Traditionally, a sheet of aluminum foil is used as a screen S. This sheet of aluminum foil is pierced with holes P in order to allow the first circulation of fluid Cl.
    According to WO 2013/184847, a rigid aluminum plate is used as an S screen and replaces aluminum foil. This aluminum plate is pierced with holes P in order to allow the circulation of fluid Cl.
    In order to allow the circulation of fluid Cl between the heating element H and the mixture M, the smoke generators 1 of the prior art systematically have holes P through the screen S. These holes P, produced at the shortest , are direct. However, they also allow coal ash and / or pieces of coal to pass through the screen S and pollute the mixture M. The arrangement of the heating element H, necessarily above the mixture M, means that said P holes are descending vertical. Also the migration of coal ash and / or pieces of coal is facilitated by gravity. The presence of ash or charcoal in the mixture M results in an unpleasant taste which degrades the smoking experience.
    There is therefore a need to provide a smoke generator for hookah which prevents or at least limits the migration of ash or coal, in order to prevent pollution of the mixture. The present invention overcomes this drawback and further provides many advantages to improve the smoker's experience.
    To this end, according to a first aspect, the invention relates to a smoke generating device for hookah, comprising a bowl and a hearth, the bowl being shaped to take place at the top of a hookah chimney and comprising a receptacle suitable to accommodate a smoking mixture, the hearth being shaped to be placed at the top of the bowl above the mixture, being capable of accommodating a heating element and comprising a base, capable of supporting the heating element and of communicating its heat to the mixture , and a cover closing the hearth, the device being shaped to allow a first circulation of fluid from the hearth to the receptacle, the first circulation comprising at least one baffle.
    This advantageously allows the ash or fuel debris not to leave the hearth to pollute the smoking mixture.

    The principle of the invention is illustrated in FIG. 3. The heating element H is arranged above the mixture M from which it is separated in a substantially sealed manner by a screen S comprising no drilling. The smoke generator 1 according to the invention allows the necessary first circulation of fluid Cl, but is shaped so as to force said first circulation of fluid Cl between the heating element H and the mixture M to present a baffle, so that the path of the fluid is necessarily indirect, non-rectilinear and more preferably along a path comprising at least one ascending section A.
    The device 1 smoke generator for hookah 10 according to the invention, as illustrated in FIGS. 4-7 comprises a bowl 2 and a hearth 3. The bowl 2 is shaped to take place at the top of a chimney 11 of hookah 10 and comprises a receptacle 20 capable of accommodating the mixture M. The hearth 3 is shaped to be placed at the top of the bowl 2 above the mixture M. The hearth 3 is capable of accommodating a heating element H.
    The hearth 3 comprises a base 4 and a cover 5. The base 4 is able to support the heating element H. The base 4 forms a screen S avoiding too rapid combustion of the mixture M in direct contact with the heating element H. The base 4 is a good thermal conductor in order to communicate its heat to the mixture M. The cover 5 is assembled with the base 4 to close the hearth 3, around the heating element H.
    According to an important characteristic, the device 1 is shaped to prevent direct circulation between the hearth 3 which contains the heating element H and the receptacle 20 of the bowl 2 which contains the mixture M. On the contrary, the device 1 is shaped to allow a first circulation of fluid C1 from the hearth 3 to the receptacle 20 by forcing this first circulation C1 to include at least one baffle. Thus there is no direct rectilinear path, in direct view, between the hearth 3 and the receptacle 20. The first circulation C1 of fluid between the hearth 3 and the receptacle 20 is indirect, not rectilinear.
    Advantageously also, the first circulation C1 is shaped so as to impose on the fluid at least one ascending section A. This advantageous characteristic makes it possible, by using gravity, to prevent ash or coal debris, naturally heavier than air, to follow the first circulation Cl and reach the mixture M. According to one embodiment, the fluid enters the first circulation Cl from the top of the hearth 3, forcing the fluid to rise according to the ascending section A.
    In order to conform the first circulation Cl, the cover 5 comprises at least a first pipe 51 formed in the thickness of the cover 5 capable of allowing the first circulation Cl.
    According to a possible embodiment, the first pipe 51 begins at a hole 55. Here the cover 5 has an outer wall 52 and an inner wall 53 spaced apart so as to provide at least one passage between the two in the thickness of the cover 5. The hole 55 is made, advantageously in the ceiling of the cover 5, in the single internal wall 52. The first pipe 51 continues between the two walls 52, 53 until it descends towards the base 4. At least one passage 45 passing through the base 4 facing allows the pipe 51 to open into the receptacle 20, containing the mixture M. The junction between the cover 5 and the base 4 is substantially sealed, at least at the level of said at least one passage 45. The volume inside the hearth 3 is not in communication with said at least one passage 45, so as not to reproduce the drawback of the prior art.
    According to an alternative embodiment, without a passage 45 passing through the base 4, the pipe 51 comprises a sealed bypass of the base 4 from the outside, beyond its periphery.
    It can be seen, by comparing the schematic diagrams of the prior art, FIG. 2, and of the invention, FIG. 3, that the length of the first circulation Cl, or what is equivalent, the length of the first pipeline 51 is greatly extended by the invention, relative to a length substantially zero according to the prior art. Thus by its positioning in the cover 5 the pipe 51 can advantageously be shaped to have a length of at least 1 cm, preferably at least 3 cm, or even more.
    The cover 5 can be made of any material, as long as it withstands the thermal stresses caused by heat, such as a plastic material, a glass, a ceramic or even a metallic material. However, according to another advantageous characteristic, the cover 5 is made of a material which is a good thermal conductor. This material can be a light alloy, for example aluminum. Thus, the significant length of pipe 51 forms a heat exchanger which, in relation to the ambient air present around the external wall 52 of the cover 5, produces a dissipator capable of cooling the fluid flowing therein. The path length here is an advantage in that on the one hand it strengthens the cooling effect and on the other hand that it provides a regulating effect. It follows that the fluid passing through the first circulation Cl, using said at least one pipe 51, emerges with a regulated temperature, substantially constant over time, despite the possible variations in the temperature of the heating element H. This is particularly advantageous for a good controlled combustion of the mixture M and contributes to improving the experience of the smoker. In addition, this thermal regulation effect advantageously renders unnecessary any means for adjusting the intensity of the heating element H, for example a means for adjusting the combustion by means of an adjustable air inlet.
    According to another important characteristic, the device 1 is further shaped to allow a second circulation C2 allowing air to enter the hearth 3, which is substantially central from the bottom. It is a question here of the combustion air which comes to join the heating element H in the hearth 3 in order to allow its combustion.
    According to the prior art, the combustion air was directly introduced into the hearth due to the absence of a cover or via at least one vent made in the cover, in the ceiling and / or in the side walls of the cover. This can cause difficulties in producing combustion of the heating element. One answer proposed by certain devices of the prior art is a device allowing the flow of incoming air to be adjusted, in order to increase it at the start of combustion, then to reduce it after combustion is well established. This degrades the smoker's experience by having to change the setting several times during a session.
    According to the invention, the possibility of a low air intake advantageously makes it possible to carry out a second circulation C2 carrying out a natural draft, which is maintained alone and which moreover is self-regulating according to demand: increasing starting, when the device 1 is cold, and then decreasing as the device 1 heats up.
    This is made possible by an adapted conformation of the device 1. The bowl 2 is arranged around and comprises a central chimney 21 passing axially axially capable of allowing the smoke produced to reach the chimney 11 of the hookah 10. Also the bowl 2 comprises a lower part 22 shaped to allow assembly of the bowl 2 and the device 1 at the top of the chimney 11 of the hookah 10. This assembly can be achieved by any means, for example by interlocking. This assembly is advantageously smoke-tight. The bowl 2 also comprises an upper part 23 comprising the receptacle 20. The upper part 23 is shaped to support the hearth 3. The assembly between the bowl 2 and the hearth 3 can be carried out by any means, for example by interlocking. This assembly is advantageously smoke-tight. The bowl 2 also comprises at least a second pipe 24. Such a second pipe 24 passes substantially throughout the bowl 2 axially and connects an inlet 241 to an outlet 242 by means of a conduit 243 substantially parallel to the central chimney 21. An inlet 241 is provided in the lower part 22, preferably radially and peripherally, so as not to disturb either the path of the smoke in the chimney 21,11, or the assembly of the bowl 2 on the chimney 11. The shape and the positioning radial of the inlet 241 guarantees that this inlet 241 is not blocked, including by a larger hookah at the interface of the chimney 11 with the bowl 2. An outlet 242 is provided in the upper part 23, preferably substantially axially and centrally, insofar as the chimney 21 allows it, so as to bring air into the hearth 3, directly under the heating element H. An outlet 242 is disposed directly under the base 4 . To to allow the passage of air, the base 4 comprises at least one substantially vertical passage 41. A bushing 41 crosses the base 4 opposite an outlet 242 and vertically connects, in a substantially sealed manner, an outlet 242 with the interior of the hearth 3, thus extending a second pipe 24. The base 4 advantageously comprises as many bushings 41 that the bowl 2 comprises second pipes 24, four in the illustrated embodiment. These pipes 24 and crossings 41 are able to be arranged opposite so as to form a second extended pipe 24,41. This advantageously allows, by natural draft, to supply air with combustion of the heating element H in the hearth 3.
    According to an advantageous embodiment, the base 4 comprises, on the hearth side, around the outlets of the bushings 41, a groove 46, facilitating the outlet of the air, even when a piece of coal is placed in line with a bushing 41 .
    It should be noted that such a second circulation C2, ensuring a draft by an air inlet from the bottom, is advantageously made possible by the fact that the first circulation C1 no longer passes through the base 4. Otherwise there would be a risk of short circuit, the draft air directly joining the chimney 21.
    According to an advantageous embodiment, more particularly visible in Figures 5,7,9,15,16 the cover 5 further comprises at least two walls 52,53. As previously described, these two walls 52, 53 in that they form a space in the thickness of the cover 5 allow the passage of at least one first pipe 51. They also form, as described above, a heat exchanger making it possible to regulate the temperature of the air circulating there. Extending the presence of a vacuum between the two walls 52, 53, beyond the mere need for passage of at least one pipe 51, to the entire surface of the cover 5, has another advantage: the outer wall 52 is significantly less hot, thus being separated by a space from the wall 53, which is very hot due to its proximity to the heating element H. This makes it possible to guarantee that the outer wall 52 remains much cooler and limits the risk of burns for a user.
    The addition of a third, or even a fourth wall, makes it possible on the one hand to increase the length of the baffle and the first pipe 51 and on the other hand to cool the outermost wall even more.
    In order to further reinforce the anti-scalding effect, and advantageously allow manipulation of the hearth 3, including when it is hot, the cover 5 also comprises a handle 54 made of thermal insulating material. This thermal insulating material may be any material, such as a plastic material, leather or wood, and may for example be silicone. The handle 54 is preferably annularly shaped into a ring peripherally surrounding the cover 5. While the prior art provided for a removable handle, such as re-use of charcoal tongs, the invention incorporates a permanent handle 54, which more reduces the risk of burns.
    According to another characteristic, more particularly illustrated in Figures 8,9,10,12,14-16 the cover 5 and the base 4 advantageously comprise complementary means 44,56 for mutual locking. Thus according to the illustrated embodiment, at least one hook 56, disposed at the bottom of the cover 5, is able to be engaged vertically in at least one slot 44 formed in the base 4. A rotation simply allows said at least one hook 56 to come to lock in said at least one slot 44. This makes it possible to close the hearth 3 by securing the cover 5 on the base 4. A rotation in the opposite direction also makes it possible to separate them. Advantageously, the same number of slot 44 and hook 56 are present and opposite. The complete hearth 3, comprising the lid 5 and the integral base 4, can thus be manipulated by gripping it by the lid 5, advantageously by its handle 54. These characteristics greatly simplify the handling and cleaning operations of the device 1, including while still warm.
    The locking means 44, 56 have a degree of angular symmetry under multiple or equal to that of the circulations C1-C3. Thus in the preferred embodiment illustrated, all the C1-C3 circulation have a degree of symmetry of 4, that is to say four elements angularly distributed at 90 °. It is the same for the locking means 44, 56 which have an equal degree of symmetry, ie 4, but which could also be under multiple, either 2 or 1
    Another degree of symmetry, even or odd: 2, 3, 5, ..., is possible and equivalent, as long as it remains identical or submultiple between the locking means on the one hand and the circulations on the other part, to allow them to be inserted. Thus, for example with a degree of symmetry of 3, there would be 3 pairs of locking means, preferably angularly equally distributed, that is to say every 120 °, interspersed with circulations C1-C3, also 3 in number, preferably angularly equireparted, or every 120 °.
    According to the illustrated embodiment, a slot 44 is adjacent to a passage 45, so as to limit the number of machining operations by allowing a common production. The slot 44 is the small cut closer to the center, while the passage 45 is the larger cut out.
    According to another characteristic, the underside of the base 4 and the upper part 23 of the bowl 2 are shaped to assemble in a substantially sealed manner. If as shown, the two parts are circular, the upper part 23 of the bowl 2 may for example have a bore in which is housed the cylindrical base 4. The assembly must advantageously be able to be carried out or disassembled by hand. A slightly tight fit ensures a smoke tightness. It has been seen that the base 4 is advantageously made of metallic material. The bowl 2 can be made of any material, for example glass, metal, ceramic or plastic. According to a preferred embodiment, the bowl 2 is made of food grade silicone. If the bowl 2 is made of an elastic material, such as an elastomer, its elasticity is advantageously used to ensure sealing.
    The bowl 2 and the base 4 cooperate for different functions, such as the second circulation C2 ensuring the draw, already described, and others described further on, which advantageously benefit from alignment. Thus, for the second circulation C2, a second pipe 24 disposed in the bowl 2 is advantageously aligned with a bushing 41 disposed in the base 4. To ensure this alignment, the base 4 and the bowl 2 respectively comprise complementary indexing means 42.27. These indexing means 42, 27 ensure an indexed position in rotation and an anti-rotation function. This is more particularly visible in Figures 10-13. The base 4 comprises at least one indexing means 42, here a lug 42, capable of engaging an additional indexing means 27, here a slot 27, arranged opposite in the bowl 2.
    Like the locking means 44,56, the indexing means 27,42 have a degree of symmetry under multiple or equal to that of the circulations C1-C3.
    According to another characteristic, more particularly visible in Figures 11,13, the bowl 2 further comprises a wall 28 separating the receptacle 20 from the chimney 21. This wall 28 of substantially annular shape, thus delimits a receptacle 20 in substantially toric shape. This wall 28 advantageously makes it possible to contain the mixture M in the peripheral receptacle 20.
    In order to allow the smoke, produced from the mixture M in the receptacle 20, to reach the chimney 21 along a substantially horizontal path, the wall 28 is advantageously cut out from at least one opening 29.
    In the smoke generator 1 according to the invention at least three circulations of fluid C1-C3 coexist. The first circulation of fluid C1 between the hearth 3 and the receptacle 20 via said at least one first pipe 51 and the second circulation C2 of low air inlet for drawing via said at least one second pipe 24, 41 have already been described. These circulations cross tightly, without mixing the fluids they carry.
    It is advisable to add a third substantially horizontal smoke circulation C3 between the receptacle 20 and the chimney 21. This is more particularly visible in FIGS. 14-16. To this end, the device 1 comprises at least a third pipe 43. Said third pipe 43, substantially horizontal, in order to pass through the wall 28, is disposed in said at least one opening 29, if the latter is present. Such a third pipe 43 must be disposed at the interface between the base 4 and the bowl 2, for example within an exchanger part, further comprising said at least one substantially vertical crossing 41.
    As illustrated more particularly in FIGS. 14-16, in the illustrated embodiment, this exchanger is produced in the base 4. Alternatively, it could be produced in an independent part or alternatively in the bowl 2.
    Said at least one third pipe 43, substantially horizontal, crosses tightly, said at least one second pipe 24, 41, substantially vertical. For this, said at least one third pipe 43 is angularly offset relative to said at least one second pipe 24,41. This is more particularly visible in Figures 12,13,7,14-16. According to the illustrated embodiment, a first number of bushings 41 is made, allowing the second line C2, here equal to 4. Advantageously, these bushings 41 are angularly distributed equally, that is to say here every 90 °. The same number of third pipes 43 is produced. Advantageously, these pipes 43 are also angularly distributed evenly, here every 90 °, by shifting them, in order to interpose them with the bushings 41, substantially at an angle of 45 °.
    In an embodiment comprising 3 bushings 41, advantageously equally distributed every 120 °, it is advisable to have 3 third pipes 43, advantageously angularly distributed equally every 120 °, by shifting them, in order to interpose them with the bushings 41, substantially d 'an angle of 60 °.
    It has been seen that the fluid coming from the hearth 3, via the first circulation Cl using at least one first pipe 51, arrives in the receptacle 20 via at least one passage 45 formed in the base 4. This fluid, mainly comprising hot air, allows the combustion of the mixture M and the smoke thus produced borrows the third circulation C3 to join the chimney 21. Advantageously, and as more particularly visible in FIGS. 14-16, in order to increase the length 47 of the path of the fluid with the mixture M, the distance 47 between the first circulation C1 and the third circulation C3 is maximized. For this, the distance 47 between the exit from the first circulation Cl, either the exit from a first pipe 51 at a passage 45, and the entry from the third traffic C3, or the entry to a third pipe 43, is maximized. In the preferred embodiment illustrated, 4 passages 45 are present, angularly distributed, ie every 90 °. Similarly, 4 third pipes 43 are present, angularly distributed, ie every 90 °. Also the maximization is achieved by angularly shifting, here by 45 °, the 4 passages 45 and the 4 third pipes 43.
    According to another characteristic, the cover 5 also comprises at least one lateral vent 57, preferably in the lower part. Such a lateral vent 57 constitutes an additional air inlet. It is important to note that such a lateral vent 57 passes completely through the cover 5 in a sealed manner with respect to the space between the two walls 52, 53 and with respect to said at least one first pipe 51 This can be seen more particularly by comparing Figures 6 and 7 between which the device 1 has been rotated 45 ° around the axis of the chimney 21 or again in Figure 9. At a side vent 57 a continuous fabric joins the two walls 52, 53 in a sealed manner. This is more particularly visible in the lateral vent 57 of FIG. 9 or in that of FIG. 16.
    In the illustrated embodiment, the side vents 57, 4 in number, are advantageously angularly distributed equally, ie every 90 °. Similarly, the first pipes 51, and the facing passages 45 which extend them into the base 4, are 4 in number and are advantageously angularly distributed equally, ie every 90 °, advantageously offset substantially by an angle of 45 °, so to be interposed between the side vents 57.
    According to another characteristic, the cover 5 also comprises at least one upper vent 58, preferably at the top of the cover 5.
