Description

The present invention relates to a hookah heat distribution device for a hookah, particularly a hookah.

STATE OF THE ART

Flavored tobacco is smoked in a hookah, especially a shisha. The tobacco is heated by a hot medium such as charcoal. The heating causes the molasses previously absorbed by the tobacco to evaporate. The steam generated is passed through a column of smoke. A valve opening is attached to a water vessel so that the vapor passed through water and thereby cooled down is directed to a smoking person via a hose and a mouthpiece.

Devices are known from the prior art, with which the tobacco is heated by means of glowing coal in order to efficiently release the molasses, in particular an aromatic liquid.

Such a device is for example in WO 2014/016088 A1 described. In the WO 2014/016088 A1 a portable hookah is shown with tobacco lying on a plate. The plate can be pivoted about a central axis, so that a first valve mechanism can be adjusted between an open position and a closed position. Furthermore, a second valve mechanism can be adjusted between an open position and a closed position by rotation of a mouthpiece. No drive device, for example no electric motor, is designed here, and no homogenization of the heat distribution is achieved as a result.

the WO 2017/178930 A1 discloses a consumable hookah article 10 disposed in a hookah bowl comprising an electric igniter. A substrate for forming an aerosol can be used individually or sequentially. Furthermore, the substrates rotate about an axis, each substrate having an aerosol exit opening opposite an ignited combustible one Align heat source. Here, too, no drive device, for example no electric motor, is provided to rotate the heating means, and the arrangement also does not serve to heat the substrate homogeneously.

the DE 43 28 243 C1 discloses a smoking or inhalation device for smoking tobacco or another smoking substance, the device comprising a hot air generator, an air inlet opening, a heating device, an air outlet nozzle, a reservoir and a drive device. Ambient air enters the hot air generator directly through the air inlet opening and can flow past the heating device. Thus, the ambient air is heated. The air outlet nozzle is arranged above the smoking agent that is placed in the storage container. The smoke agent is selectively heated by the heated air via the air outlet nozzle. Furthermore, the drive device causes the reservoir to rotate in order to guide the individual portions of the smoking agent past the hot air stream of the outlet opening of the air outlet nozzle, the drive device being designed as an electric motor. This is neither a coal fire nor a shisha.

the DE 198 54 008 A1 Figure 1 shows an inhalation device having a combustion chamber, a rotatable disc and an orifice, with an aerosol forming material in a portion of substrate and heating means in the combustion chamber. The disk can be rotated by an operating device, wherein the condition device can have an electrical switch which causes the disk to rotate with the aid of an electric motor. The combustion chamber can rotate with the disc. No hookah principle is described here.

the DE 20 2015 004 479 U1 discloses a hookah proposing a carbon plate between a smoke column and a cone valve. The charcoal on the charcoal plate can be arranged in such a way that the charcoal lies unevenly over the entire surface of the charcoal plate, ie only on three surfaces of the charcoal plate. No motor drive for the hookah is suggested.

In the known device, no drive device is provided for coal firing a hookah or a shisha in order to rotate the charcoal plate and/or the shisha head so that the tobacco on the charcoal plate is heated homogeneously.

However, if the tobacco in the shisha head is heated inhomogeneously, the problem arises that no intensive taste and only little steam can be generated. The coals can be provided unevenly on the coal plate and tobacco can be overheated or underheated inhomogeneously. Keeping the charcoal plate and shisha bowl at rest while heating the tobacco allows a hot spot and uneven burning of the tobacco to occur. This negatively affects the taste. Furthermore, a relatively long time is required to provide optimal firing, which can spoil the joy of smoking shisha, especially for inexperienced users.

Proceeding from the aforementioned disadvantages of the prior art, it is the object of the invention to reduce the disadvantages of the known arrangements.

The above object is achieved by a shisha heat distribution device according to the independent claim. Advantageous developments of the invention are the subject matter of the dependent claims.

DISCLOSURE OF THE INVENTION

A shisha heat distribution device for a water pipe, in particular for a shisha, is proposed, the shisha heat distribution device comprising a shisha head for receiving tobacco and a charcoal plate which is arranged on the shisha head and on which charcoal is provided.

According to the invention, it is proposed that a drive device is included, which includes a drive part, a drive wheel and a rotary shaft, and a chassis is included, which is provided with a fixing device, in particular a fixing screw, on the shisha head and with an adjusting device, in particular an adjusting screw, on the Drive device is attached, wherein by the Drive device of the carbon plate and the shisha head are rotatable relative to each other about an axis of rotation.

A chimney attachment, which has a chimney pipe, can be designed between the coal plate and the shisha bowl. Ambient air flows past the firing coals and is heated. The heated air enters the shisha head through openings in the surface of the chimney attachment, so the tobacco provided in the shisha head is directly heated by the heated air that exits through the openings. Excess heat is transported to the outside with the chimney pipe, so that heat build-up can be avoided.

The shisha head and the drive device are connected to one another by the chassis. The chassis is fixed in position on the shisha head by means of the fixing device, e.g. a fixing screw or a fixing rivet, and is attached to the drive device by means of the adjusting device, e.g. an adjusting screw. The chassis thus acts as a connecting element between the drive device and the shisha head and can be provided as a retrofit part for existing shishas or integrated, preferably in one piece with new shishas.

The relative twisting of the charcoal plate and the hookah head holding the tobacco homogenizes the heat distribution, particularly during a heating phase, so that the tobacco can be heated evenly.

Advantageously, an electric drive or a mechanical drive can be designed as a drive part of the drive device in the shisha heat distribution device, so that the drive wheel can rotate about the rotary shaft. Because the charcoal plate and/or the shisha head are connected to the drive device, preferably the drive wheel, by means of a gear, i.e. an element that transmits the rotary movement and that can also be used to change the speed between the drive part and the axis of rotation, the charcoal plate and the shisha head are relative to one another rotatable around the axis of rotation. A rubber band or a rubber roller on the transmission can be used as a transmission Drive device, preferably be arranged on an axially extending lateral surface of the drive wheel. A toothed wheel connection can of course be used between the charcoal plate or the shisha head, with the drive wheel preferably being designed as a toothed wheel in the drive device, via which the charcoal plate and the drive device can be set in rotary motion with one another.

In the shisha heat distribution device according to the invention, the charcoal plate can be rotatable about the axis of rotation with respect to the shisha head. Due to the fact that the charcoal plate is coupled to the drive device or to the drive wheel via the gearing, the charcoal plate can be driven indirectly by the drive device. When the rubber band is used as a gear, the carbon plate and the drive wheel of the drive device rotate in the same direction. When a rubber roller or gear linkage is used as the transmission, the carbon plate and drive wheel rotate in opposite directions.

Alternatively, it is conceivable that the shisha head is coupled to the drive device or the drive wheel by the gearing, so that the shisha head can be rotated. This ensures that the shisha head can be rotated about the axis of rotation with respect to the charcoal plate. Likewise, the rubber band, the rubber roller and the tooth connection can be used as a gear.

The charcoal plate and the shisha head can also rotate in opposite directions at the same time. In this case, for example, one or more rubber bands can be designed as gears, one rubber band being arranged directly on the axially running lateral surface of the carbon plate and another crossed rubber band on the axially running lateral surface of the shisha head. A gear drive or similar can also provide a combined, counter-rotating movement of the charcoal plate and shisha head.

It is advantageous that the charcoal plate and the shisha head can be rotated relative to one another when smoking. As soon as the drive device is switched on, the shisha head and/or the charcoal plate and those on it rotate unevenly lying coals. Thus, the tobacco in the shisha head can be heated homogeneously by means of the air heated by the coals. This allows for an intense flavor and lots of vapor to be generated.

Furthermore, it is advantageous that with the shisha heat distribution device according to the invention, an excessive amount of heated air cannot reach a point in the shisha head. This avoids a heat spot and burning of the tobacco at this point, which results in a bitter taste and can release unhealthy combustion residues. This can also prevent self-ignition of the shisha head. Furthermore, it is advantageous that by using the shisha heat distribution device according to the invention in the water pipe or shisha, the time for optimal firing and intensive tobacco enjoyment can be shortened.

In an advantageous further development, the rotary shaft of the drive device can be operatively connected to the carbon plate and/or the shisha head, preferably by a drive wheel, via a gear mechanism. The driving device includes the rotary shaft on which the driving wheel is mounted. An electric drive or a mechanical drive can be provided as the drive part. This allows the drive wheel to be driven by the drive part. The operative connection between the carbon plate and the drive wheel can be provided by the transmission, e.g. a rubber band, so that the carbon plate can be rotated. In addition, the shisha head can be connected to the drive device via the operative connection, with the operative connection preferably being made possible by a drive wheel. As a result, the shisha head is rotated in such a way that the shisha head rotates in the same or opposite direction of rotation of the drive wheel, depending on the gearing in relation to the drive wheel. It is also possible for the charcoal plate and the shisha head to be connected at the same time through the transmission to the drive device, preferably to the drive wheel. Thus, the charcoal plate and the shisha head rotate in opposite directions at the same time under the action of the drive device.

In a further advantageous development, an electric drive, in particular an electric motor, can be provided as the drive part. As a drive can Thus, a DC motor or an AC or three-phase motor can be used, with a DC motor would be preferable for ease of construction. By controlling the speed of the electric motor, a rotational speed of the carbon plates and/or the shisha head can be changed, for example a speed control can be achieved by a simple voltage control or an electronic control. Thus, the time for optimal heating of the tobacco is influenced. The faster the charcoal plate and/or the shisha head rotate, the more homogeneously the tobacco is heated in the shisha head. Thus, more steam can be generated at the higher speed of the electric motor in a given period of time.

In a further advantageous development, the electric motor can be connected to the mains with a cable in order to drive the electric motor. In this case, the power grid is intended as the power supply. An alternating current is thus routed via the cable to the electric motor, with a direct or alternating voltage for operating the electric motor at varying speeds being able to be provided very easily by means of drive electronics connected in between. The drive electronics can be equipped with a switch unit that makes it possible to conveniently switch the shisha heat distribution device on or off and to set the speed of the electric motor. This makes it possible in a simple manner to achieve a predefined heating time for the tobacco. Thus, a certain amount of steam can be generated.

In a further advantageous development, a preferably rechargeable battery can be provided as the power supply for the electric motor. Thus, direct current is provided by the battery to drive the electric motor. In this case, a DC motor can advantageously be used. Furthermore, the battery can be formed not only as a primary cell but also as a secondary cell. A lithium-ion accumulator, for example, can be used as the secondary cell. If a primary cell, for example an alkaline manganese battery, is used as the energy source, a new primary cell must be used for the shisha heat distribution device after it has been discharged. Compared to the primary cell is advantageous that the secondary cell can be charged again after discharge. Thus, the secondary cell is recyclable and environmentally friendly.

Advantageously, the power supply can provide a charging option for a mobile phone as a battery or mains connection, esp. a USB port and/or an inductive charging pad.

In a further advantageous development, the electric motor and/or the battery can alternatively or additionally be connected to a solar cell in order to provide electrical energy for driving the electric motor. A thin film cell or a multiple cell can be used as the power source. With a photovoltaic effect, the solar cell can convert sunlight directly into electrical energy. As a result, a DC voltage or direct current is generated by the solar cell. Advantageously, the DC motor can be arranged as a drive part of the drive device, with drive electronics being connected to the solar cell with a cable. Alternatively, it is conceivable that an AC motor or three-phase motor is used as the drive part. Thus, an inverter can be provided between the solar cell and the three-phase motor, so that the direct current generated by the solar cell can be converted into an alternating current.

Furthermore, a rechargeable battery can advantageously be provided between the electric motor and the solar cell. Thus, the rechargeable battery can be charged directly from the solar cell as soon as the battery capacity is exhausted. Furthermore, it is advantageous that the use of solar cells is free compared to other energy sources. In addition, no exhaust gases are generated when using the solar cell, as is the case with fossil fuels, so the use of the solar cell is environmentally friendly and follows the green energy concept.

In a further advantageous alternative or additionally combinable development, a mechanical drive, in particular a spring mechanism, can be included as a drive part, the spring mechanism preferably being able to be wound up with a winding stem. The clockwork can have a spring and a Include elevator gear with a tensioning device, wherein the spring is usually spirally wound. The spring can store potential energy, which can be converted into rotary motion via the winding mechanism. By turning the winding stem, the clockwork can be wound up, for example via the corresponding winding wheels of the winding mechanism. Thus, the mechanical energy or potential energy can be stored in the clockwork. Furthermore, the clockwork can be coupled to the rotating shaft, with the drive wheel being mounted on the rotating shaft, so that the clockwork and the driving wheel can be connected to one another. Thus, the drive wheel can be rotated by the stored mechanical energy of the spring. As a result, the charcoal plate and/or shisha head connected to the drive wheel via the gear can be rotated.

In a further advantageous development, a weight can be included in the drive part, with the weight preferably being able to be wound up by pulling a chain, in particular using a crank, comparable to a mechanical pendulum clockwork with weight storage, e.g. a cuckoo clockwork. The weight can be provided as a mechanical energy store in order to store the mechanical or potential energy. The weight can hang on the chain, which preferably has a crank for winding. By pulling down the chain, a weight is raised so that the mechanical or potential potential energy of the weight can be stored. The stored potential energy can be converted back into kinetic energy when the weight is lowered, so the drive wheel can rotate around the rotary shaft. This means that the charcoal plate and/or shisha head can be rotated.

In a further advantageous development, an elastic band, for example a rubber band, can be provided as the gear mechanism, with the drive device, preferably the drive wheel, being connected to the carbon plate or shisha head by the rubber band. The drive device comprises the rotary shaft, the drive part and the drive wheel, the drive part and the drive wheel being connected to one another via the rotary shaft. The elastic band can be attached to the axially running outer surface of the drive wheel and the carbon plate, thus the carbon plate can be rotatably coupled to the drive wheel.

In this case, the charcoal plate and the drive wheel rotate in the same direction. Alternatively, it is conceivable that the hookah head is designed in two parts, with the tobacco being accommodated in the upper part. The upper part can be designed as a rotatable section, while the lower part is designed to be stationary. The rubber band allows the upper part of the shisha head to be connected to the drive device, preferably to the drive wheel, so that the shisha head, in particular the upper part of the shisha head, can be rotated.

In a further advantageous development, an elastic roller, for example a rubber roller, can be arranged on the axially extending lateral surface of the drive wheel, with the rubber roller making direct contact with the carbon plate or hookah head. In this case, the rubber roller is intended as a gear to operate the charcoal plate or shisha head. The drive wheel can be connected by the rotary shaft to the drive part, which can be in the form of an electric drive or a mechanical drive. This rotates the drive wheel. The ratio of the diameter of the rubber roller to the shisha head / charcoal plate influences the speed conversion. The rubber roller can be attached to the axially extending outer surface of the drive wheel. A rotational movement of the drive wheel can be transmitted to the charcoal plate or the shisha head through the rubber roller, so that the drive wheel and the charcoal plate or the shisha head can rotate in opposite directions.

In a further advantageous development, two gear wheels can be provided as a transmission, with the first gear wheel and the second gear wheel each being formed on the axially running outer surface of the carbon plate and drive wheel. Thus, during operation, the teeth of the two counter-rotating gear wheels can mesh with one another. In this development, it is proposed that the first gear wheel be arranged on the axially extending lateral surface of the carbon plate and the second gear wheel be arranged on the axially extending lateral surface of the drive wheel, with both gears making contact with one another in the rest position. The drive wheel can be rotated with the second gear wheel through the drive part, so the first gear wheel can rotate in opposite directions with the carbon plate. Alternatively or additionally, the shisha head can have a rotatable section include, wherein the first gear is arranged on the axially extending lateral surface of the rotatable portion of the shisha head. Thus, the rotatable section of the shisha head and the drive wheel can rotate in opposite directions.

In a further advantageous development, the drive device can be designed to rotate the charcoal plate and shisha head in opposite directions at a controllable speed of 20-35 rpm, preferably at a speed of 25-30 rpm, in particular at a speed of 26 rpm to rotate against each other, preferably the number of revolutions of the drive device is adjustable. The driving device comprises the rotating shaft, the driving wheel and the driving part, the driving wheel and the driving part being connected to one another by the rotating shaft. In this case, an electric motor can be provided as the drive part in a particularly advantageous manner. If a radius of the charcoal plate or shisha head is larger than a radius of the drive wheel, a number of revolutions of the electric motor greater than 20-35 U / m is required to the number of revolutions of the charcoal plate or shisha head of 20-35 U / m, preferably from 25-30 rev/m, especially 26 rev/m. By adjusting the speed of the electric motor, the rotation speed of the charcoal plate or shisha head can be changed. This allows different amounts of vapor to be generated when smoking.

In a further advantageous development, the drive device can be set up to end a relative rotation between the carbon plate and the shisha head after a predeterminable time. In this development, it is proposed that the drive device can include a time control unit, with the time control unit having a controller. Furthermore, in this development, the electric motor can advantageously be arranged as a drive part. wherein the electric motor is connected to the timing control unit. A predeterminable time can be defined in the controller. As soon as the time is reached, the electric motor is automatically disconnected from the mains or from the rechargeable batteries. This stops the rotation of the drive wheel so that the relative rotation between the coal plate and the shisha head stops can be. Advantageously, the rotational speed can also be reduced to a standstill when the time has elapsed, ie the rotational speed can be slowed further and further. In a further advantageous development, the drive device can include a temperature sensor that can detect a temperature of the shisha head, and the temperature sensor is set up to end a relative rotation between the carbon plate and shisha head when a predeterminable first temperature is reached and/or when the temperature falls below a predeterminable second start temperature. The temperature sensor can be arranged on the shisha head in order to measure the temperature of the shisha head or tobacco. An electric motor can advantageously be provided as the drive part, but a mechanical drive can also be used for this purpose. As soon as the predefined first temperature is reached, the electric motor can be switched off. This allows the relative rotation between the charcoal plate and shisha head to be terminated. A relative rotation can be started in the starting phase or when the temperature falls below a second temperature that is lower than the first temperature, for example when there is an increased flow of smoke. It is advantageous that the temperature of the tobacco is controlled by the temperature sensor in order to generate any amount of steam and to avoid overheating or burning of the tobacco.

In a further advantageous development, the drive device can be magnetically coupled to the charcoal plate or the shisha head. At least one ferromagnetic element or at least one permanent magnet, preferably several permanent magnets, with a magnetic orientation as a south pole or north pole can be arranged on the carbon plate or the shisha head. A further permanent magnet, preferably several permanent magnets, or possibly ferromagnetic elements or a set of current coils can be provided on the drive device, preferably on the drive wheel, as a north pole or south pole, with the permanent magnet/the ferromagnetic element of the drive device having a different polarity from one polarity of the ferromagnetic element/permanent magnet of the charcoal plate/shisha bowl. With suitable electrical wiring, current coils can provide a rotating magnetic field on which the or the Can couple permanent magnetic elements / ferromagnetic elements of the rotatable carbon plate or shisha head. If the drive device is activated, the permanent magnet of the drive device or the magnetic field provided by it can rotate together with the drive wheel. Thus, the two permanent magnets or the pairing of permanent magnet / rotating magnetic field / ferromagnetic element attract each other depending on their position. This allows the charcoal plate / shisha head to rotate magnetically coupled. Alternatively, a permanent magnet can be configured on the shisha head, with the permanent magnet of the shisha head having the opposite polarity than the permanent magnet of the drive device, so that the shisha head can be coupled magnetically and carried along. Contactless coupling can advantageously be achieved in this way, so that there is a thermal decoupling between the drive device and the hot coal plate/shisha head. A thermal load on the drive device and thus a long service life can thus be increased.

In a further advantageous development, the drive device can have a further axis of rotation, which is arranged along the same axis of rotation of the charcoal plate or the shisha head, with the drive device having an arm rotating around the axis of rotation as a driver of a magnet/a ferromagnetic element with the charcoal plate or the shisha head magnetically can drive coupled. In this development, the drive device can drive a revolving arm with rotation about the axis of rotation of the carbon plate or shisha head. The cantilever arm has a permanent magnet or a ferromagnetic element at its distal end. If the drive device is switched on, the arm can rotate around the axis of rotation of the charcoal plate / shisha head. A magnet held by the arm, preferably a permanent magnet or a ferromagnetic element, revolves around the axis of rotation of the coal plate/shisha head. Furthermore, another magnet, preferably another permanent magnet, or a ferromagnetic element is arranged on the peripheral edge area of the carbon plate or the shisha head. Due to a magnetic attraction between the permanent magnet of the drive unit and the permanent magnet of the coal plate or the Hookah head can turn the charcoal plate or hookah head with the arm of the drive device. In this way, a relatively simple and non-wearing non-contact coupling of the carbon plate, which is very hot during operation, to a driver arm is achieved magnetically, with a comparable construction of the drive device as in the aforementioned exemplary embodiments being able to be used. This does not drive the charcoal plate / shisha head directly, but indirectly, in which a driver arm rotating around the axis of rotation of the charcoal plate / shisha head is driven.

In a further advantageous development, the shisha head or the charcoal plate can comprise rotating magnets with alternating polarity or one or more ferromagnetic elements, preferably on an outer circumference or a surrounding bottom or top surface, and the drive device can comprise a set of current coils that generate a rotating magnetic field can generate, whereby the magnets / ferromagnetic element of the shisha head or the coal plate can attach themselves to the magnetic field generated by the current coils. For this purpose, it is proposed that the charcoal plate or the shisha head have several magnets, in particular several permanent magnets, or one or more ferromagnetic elements, which are arranged circumferentially around the axis of rotation of the charcoal plate or the shisha head on an outer circumference or on the bottom/top surface. Furthermore, a plurality of grooves can be formed in the drive device, in which the coils are arranged circumferentially in a ring shape, with the number of coils and the number of magnets advantageously being able to be formed the same. If the drive device is switched on, a current is conducted in the coils in alternation in such a way that a rotating magnetic field results. As a result, circulating magnetic fields can be generated so that the magnets of the shisha head or the charcoal plate are attracted by the magnetic fields and can rotate with the drive device, or eddy currents are induced in the ferromagnetic element in such a way that a magnetic coupling is established, which in a rotation resulted. In this way, an electric motor with the drive device as a stator and the charcoal plate / shisha head as a rotor can be used as a synchronous motor (for permanent magnets) or as an asynchronous motor (for ferromagnetic elements) are provided, so that a rotational movement is achieved without contact and thermal decoupling is made possible.

A specific embodiment of the hookah heat distribution device includes a temperature controller, such as a thermostat, designed to keep the tobacco at as constant a temperature as possible, or at least within a predetermined temperature range. The temperature controller preferably includes a temperature sensor and a controller that drives the drive of the carbon plate depending on the measured temperature. As a regulator z. B. a simple P controller, but also any other type of controller can be provided. The temperature sensor can B. in or on the shisha head, on the charcoal plate, in the fireplace or installed elsewhere.

A hookah according to the invention can also have a communication interface, such as B. include a Bluetooth interface via which the shisha can communicate with mobile devices. Via the interface z. B. data of any kind or possibly also control commands are transmitted.
