BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to the field of heat-not-burn tobacco devices, more particularly to devices that employ an electric heating element to generate vapor from tobacco.
2. Discussion of the State of the ArtThe use of charcoal as a heat source dates back to the dawn of human civilization. Compared to the material from which it is pyrolyzed from, charcoal burns at a higher temperature, with hardly a visible flame, and releases only heat with minimal soot and smoke. Consequently, throughout the ages, charcoal has been regarded as an indispensable source of thermal energy for a variety of industries. Particularly, since the iron age, charcoal's exceptional thermal capabilities have been harnessed for iron smelting, glassmaking, and the working of precious metals. Around the middle of the 16thcentury, charcoal's influence as a crucial heat source extended to the realm of hookah smoking. In a traditional hookah, tobacco is packed into a bowl under a thin sheet of aluminum foil. After that, hot charcoals are placed on top of the foil to vaporize the tobacco underneath.
Unfortunately, the adoption of charcoal use for hookah smoking purposes has a plethora of drawbacks. From an environmental point of view, the industrial production of charcoal, partly fueled by hookah smoking, involves the felling of large swathes of forestland that directly contributes to forest degradation. Moreover, charcoal production and utilization poses a hefty environmental cost as it entails substantial emission of a variety of toxic gases which contribute to the greenhouse effect. From a hookah user's point of view, the preparation of flaming charcoal is a tedious and time-consuming process. Additionally, charcoal use results in remnant ashen residue that causes a bothersome mess. Moreover, the heat generated by charcoal cannot be controlled. More often than not, the unregulated heat results in tobacco combustion rather than vaporization. This leads to the production of thousands of chemicals which are hazardous to a person's health. Furthermore, the heat associated with burning charcoal is inconsistent as the embers cool down after a period of time. As such, the coals must be replaced at progressive intervals to ensure proper tobacco vaporization. In addition to that, the use of flaming charcoal brings about the danger of inhaling noxious gases that may put the user at risk of grave health consequences. Also, handling hot charcoal poses a serious burn hazard.
The substitution of charcoal with an electrically powered heat source presents a solution to eliminate the complications arising from charcoal use for hookah smoking purposes. Nevertheless, simply replacing charcoal with an electrically powered heating element does not address key points such as the optimization of the flavor, smoke production, and duration of the hookah session, matters which are crucial for the end user. Without a strategic configuration of the electric heating element with respect to a hookah bowl, the hookah session, devoid of vapor production, is usually cut short due to the charring of the combustible substance. The resulting charred combustible substance can be comparable to charcoal in terms of harmful compounds production.
As such, what is clearly needed is a strategically designed integration of the electrically powered heat source with a hookah bowl in order to optimally vaporize the combustible substance for hookah smoking.

DETAILED DESCRIPTION OF THE INVENTIONThe inventor provides a device which aims to replace charcoal as the heat source for hookah smoking with an electrical heating element. In particular, the invention focuses on the overall integrational strategy of the heating element, including the heater's adjuncts, with respect to a hookah for optimal combustible substance vaporization. The present invention is described in enabling detail in the following examples, which may represent more than one embodiment of the present invention.
FIG.1 is a perspective view of a Mu'assalvaporizer100 positioned above ahookah101 right before operation according to an embodiment of the present invention. In such an embodiment,vaporizer100 comprises avaporization section102.Section102 is the compartment responsible for the vaporization of the combustible substance.Section102 can be held by ahandle103. Situated on the bottom side ofsection102 is a heat source, an exposedheating element105, with all its related appendages. Element105 provides the necessary thermal energy to vaporize the combustible substance directly underneath it inbowl104. Further attached toplate103 is acover ring106. Moreover, separatingelement105 and the combustible substance is analuminum barrier107. Bothring106 andaluminum107 allow for an enhancement in heat distribution. In one embodiment,ring106 has a diameter such that it outer periphery coincides with the outer periphery ofbowl104. Further describing the embodiment,vaporizer100 comprises anelectronics section108.Section108 holds the electronic components ofvaporizer100, namely a power source, charging port, microchip processor, ON/OFF button, voltage modulator, dial potentiometer, and all the required electric wires.Section108 is situated on anashtray plate109 incorporated in most traditional hookahs. Apower cable110links section102 withsection108.Element105 insection102 derives its power fromsection108.
FIG.2 is a perspective view of theMu'assal vaporizer100 ofFIG.1 during operation according to one embodiment of the present invention. Firstly,section108 is installed onplate109. After that,bowl104 containing the combustible substance is mounted onhookah101. Following that,vaporization section102 is inserted around and overbowl104 such that thevaporization section102 covers the outer periphery ofbowl104 and the upper limit of the bowl comes in contact withring106. Next,cable110 connectssection102 withsection108. Finally,vaporizer100 is turned ON to begin vaporizing the combustible substance packed intobowl104.
FIG.3 is a perspective exploded view of thevaporization section102 of theMu'assal vaporizer100 ofFIG.1 according to one embodiment of the present invention. The figure shows the inner components' positioning which is detrimental for optimal combustible substance vaporization.Section102 comprises ahandle103 fixed to areflector plate301. According to one embodiment,plate301 made from supermirror stainless steel. Theheating element105 andcover ring106 are fixed to theplate301.
In one embodiment of the present invention,element105 may be any form of electrical heating element that can convert electric energy into heat energy. In a preferred embodiment,element105 is a circular metallic-ceramic heating element. The present inventor realized in an inventive moment that if the actual heat source, in thiscase element105, is perforated, as depicted inFIG.1, then the benefits are twofold. Firstly, air drawn into the hookah passes through the heater instead of around it, thus efficiently heating this air, not to mention allow for its flow without hindrance. The drawn air has two main functions. Primarily, it is a medium by which the vapor produced in the vaporization chamber makes its way to the user. As utilized henceforward, the phrase “vaporization chamber” shall refer to the cavity in which vaporization takes place, namely in the inner boundaries ofbowl104. Moreover, the drawn air greatly facilitates the vaporization of the combustible substance by providing an oxygen-rich environment within the vaporization chamber. Another benefit attributed to the perforations is that the heater, being perforated, has a reduced area of heat transfer. This prevents the combustible substance from being consumed prematurely resulting in an extended hookah session in which the flavor of the vapor emitted from the combustible substance remains fresh. The perforated heater may be likened to a perforated piece of aluminum foil in a traditional hookah. As such, in a preferred embodiment, the perforations may be around 1 millimeter in diameter. In an optional embodiment, more than one heating element may be employed such that none, one, or more than one of those heating elements may be perforated.
In the shown embodiment, right aboveelement105 andring106 is areflector plate301.Plate301 may be formed of a material with low thermal conductivity. In one embodiment,plate301 is made of supermirror stainless steel.Plate301 ensures the preservation of heat produced by the electrical heating elements. This translates to less electrical energy needed to be supplied to the heater. As with the heater, the plate is perforated throughout its thickness to allow for adequate airflow.
In the shown embodiment, attached toplate301 is ahandle103. It enhances the safety of the product as the user can holdsection102 by the provided cutout without the risk of burn injuries.
FIG.4 is a top elevation view of theelectronics section108 of the Mu'assal vaporizer ofFIG.1 with its cover removed. In the shown embodiment, apower source401 is positioned within the boundaries ofsection108.Source401 supplies the voltage needed topower element105. The voltage available depends on the heater employed to reach the necessary vaporization temperature. In a preferred embodiment, the voltage ofsource401 is 16 Volts. Additionally, an ON/OFF button402 and aDC charging port403 are held in place by the exterior ofsection108. Further shown in the embodiment is amicrocontroller unit404.Unit404 receives signals from a sensor or group of sensors and outputs commands in response to these signals. Since the temperature ofelement105 is directly proportional to the voltage supplied to it, the element's temperature may be adjusted by implementing the use of avoltage modulator405. In the described embodiment, adial potentiometer406 may controlmodulator405 to either raise or lower the voltage supplied toelement105. Consequently, the temperature ofelement105 may be adjusted by the user depending on their preference.Section108 has ahollow center407. Withcenter407,section108 may be installed around the stem ofhookah101, specifically onplate109 as depicted inFIG.2. In a traditional hookah,plate109 acts as an ashtray that catches the ash falling from the expended coals. A plate acting as an ashtray is incorporated in most hookahs. With the usage of an electrical heating element, the usage of the plate as an ashtray becomes redundant. This situation was exploited by designingvaporizer100 such thatsection108 holding the electronic components may be situated onplate109 thus making a new-found use of the plate.
It will be apparent to one with skill in the art that the Portable Electronic Mu'assal Vaporizer may be provided using some or all of the mentioned features and components without departing from the spirit and scope of the present invention. It will also be apparent to the skilled artisan that the embodiments described above are specific examples of a single broader invention which may have greater scope than any of the singular descriptions taught. There may be many alterations made in the descriptions without departing from the spirit and scope of the present invention.
