Description

The utility model relates to the field of smoking accessories, namely to hookahs, and can be used as an autonomously heated hookah bowl.

From the publicly available prior art in the designated area, it is known that a hookah is a special device for smoking, consisting of several basic elements: a flask filled with liquid, shafts, bowls (cups) for tobacco and a hose with a mouthpiece. Also, often a hookah is additionally equipped with a saucer (plate) for placing objects and settling ash, a valve for blowing the hookah and preventing air from entering the hookah from the room, a cap for controlling the temperature of smoking a hookah hookah//[electronic resource] https://principraboty.ru/princip-raboty-kalyana-kak-ustroen-kalyan/ (accessed 06/04/2021).

The main purpose of the hookah bowl is the location of the smoking mixture in it. Bowls for hookahs currently differ in material, shape, size, location. According to the material, the bowls are made both traditional clay or ceramic, and silicone, metal, fruit, glass, stone. According to the shape of hookah bowls, they are classic in the form of Turks with sloppy edges and holes of different sizes, in the form of fanel with a larger capacity, old school fanel, alien with a limited capacity, vortex, with ribs, Evil / killer. Small, deep and flat bowls stand out in size. By location - internal and external (site "Planet of hookahs"//What are the hookah bowls//[electronic resource] URL: https://planetakalyanov.ru/kalyan/chasha-kalyana (accessed 06/04/2021).

At the same time, the heating of the smoking mixture (tobacco, impregnation) in the bowl of the hookah in the classic version is carried out by placing a kalaud / mesh / foil with coals in the bowl to heat tobacco. At the same time, the smoking mixture is placed in the bowl before smoking the hookah, and in the process of smoking, it is periodically stirred, various impregnations are added, and tobacco is replaced. Coals, in turn, in the process of smoking can be gradually replaced to maintain the temperature level.

The main disadvantages of using coals for heating the smoking mixture are the fire hazard of this method, the likelihood of overheating the smoking mixture and the release of acrid tobacco smoke as a result, the complexity of the process of controlling the heating temperature of the smoking mixture and the amount of smoke emitted, which requires a certain level of experience and skill of the user, and , as a result, the uneven process of heating the smoking mixture.

To eliminate the above shortcomings, now more and more often in hookahs, in contrast to the classical scheme of heating the smoking mixture, solutions for heating it without the use of coals are used.

At the same time, a significant part of the design solutions and methods for heating the smoking mixture in a hookah without the use of coals are electronic hookah bowls. Electronic bowls are a symbiosis of a traditional hookah and a fashionable steam generator. An electronic bowl is installed in a hookah instead of a standard bowl and differs from it in that it uses liquid preliminarily filled into the bowl as a smoking mixture, the bowl itself is airtight. The principle of operation of the electronic bowl is that during the tightening, the heating of the evaporator coil is automatically turned on, which receives liquid from the cartridge, and the resulting vapor passes through the flask with liquid in the same way as a conventional hookah. In this case, the user can select the required evaporation temperature, adjust the amount of incoming steam. The advantages of the electronic bowl are the autonomy of the bowl due to the presence of an electrical power source (battery, batteries) in the bowl, ease of use and regulation of the temperature and amount of steam, saving the smoking mixture, fire safety, and the absence of tobacco smoke. The main disadvantages are the high cost of the electronic bowl, the limited charge of the device, the laborious process of washing the bowl, and, most importantly, the fact that the process of smoking using an electronic bowl does not bring the same sensations as when smoking a classic hookah (site "Planet of Hookahs"// What are hookah bowls? waste of money?//[electronic resource] URL: https://kalyanter.ru/elektronnaya-chasha-dlya-kalyana; site "ALL ABOUT HOOKAHS"// Electronic hookah bowl square e head//[electronic resource] URL : https://www.4kalyans.ru/electro/elektronnaya-chasha-dlya-kalyana-square-e-head.html).

Other solutions for heating the smoking mixture in a hookah without the use of coals are devices and methods using either a heating element external to the hookah or a heating system built into the hookah device. In both cases, heating is carried out with the help of electricity.

The following can be distinguished as examples of patented technical solutions. In the decision on the foreign patent for the invention No. US2019159514A1 (priority date 01/30/2019, copyright holders FRANK MAXIMILIAN [US]; GAMMERLER GUNTER [US]; MG HEAT LLC [US]), the heating of the smoking mixture in the hookah bowl is carried out by an electric heating element installed on the bowl hookah and connected to the mains using a wire with a switch and a plug.

Solutions on Russian patents for inventions No. 2720891 and 2728445 (priority date 04/05/2017, copyright holder PHILIP MORRIS PRODUCTS S.A. (CH) are electronic hookahs using smoking liquid and its evaporation system containing an electric heating element, batteries that control electronics.

In the decision on the Russian patent for utility model No. 140206 (priority date 10.12.2013, copyright holder Vladimir Valeryevich Barabash), a system for heating the smoking mixture in a hookah bowl, consisting of a heater, a heating element and carbon, is disclosed. Carbon already directly heats the gas mixture. In this case, the heater is connected to the power source by means of a wire.

Decision on foreign utility model patent No.
DE10212045A1 (priority date 03/19/2002, copyright holder
SELT HERMANN JOSEF) is not a hookah, but a smoking pipe for medical purposes. However, this patent discloses a design that has features similar to the presented solution, namely, at the bottom of the tube bowl there is an electric heating element that heats the substance for evaporation when inhaled. In this case, the battery is separated from the handset, and a switch is installed on the handset.

In the decision on the foreign patent for the invention No. EP2292108A1 (priority date 02.09.2009, copyright holder NOUVELLE GENERAL TRADING & CONTRACTING CO W L L [KW]), tobacco is heated in the hookah bowl by an electric heater, which is connected with a wire with a holder to the battery pack, which is located at the bottom of the hookah (in the flask) and can be connected to a charger for recharging. That is, in this solution, the heating system of the smoking mixture in the bowl of the hookah is built into the design of the hookah itself.

In the technical solution according to the foreign patent for the invention No. US2011186059A1 (priority date 02/01/2010, inventors MORESHEAD MAUREEN SUE [US]; MOUHANNA MICHAEL [US]), tobacco is heated in a ceramic bowl of a hookah by an electric heater in the form of an ignition coil, which is connected through terminals and battery switch. The battery itself is located in the area of the hookah shaft.

The disadvantages of the listed patented solutions are the complex and, as a result, expensive nature of their design, namely the use of many elements in the smoking mixture heating system (refers to patents No. 140206, EP2292108A1), the use of smoking liquid instead of a smoking mixture with tobacco, which reduces the level obtained from satisfaction of the smoking process (refers to patents No. 2720891 and 2728445), the absence of a heating element, and, as a result, the entire hookah device has autonomy of operation, since the heating element must be constantly connected to the power supply or a separate battery (refers to patents No. 140206 , US2019159514A1, DE10212045A1).

As for solution No. US2011186059A1, this design with the location of the battery in the hookah shaft is not only complex and time consuming during operation, since in order to charge the battery, it is necessary to disassemble the hookah shaft, remove the battery from there, charge it, and then reinstall it in the shaft, but the heating element (spiral) also heats up to 400 degrees, which can cause uneven heating of the smoking mixture, namely, drying and smoking of the upper layer of the smoking mixture, which will lead to the ingress of caustic tobacco smoke both into the lungs of the smoker and into the room.

To eliminate the above shortcomings, the applicant previously proposed a technical solution for a utility model patent No. 207666 "Hookah bowl with a heated insert" (priority date 06/29/2021, copyright holders Pavel Sergeevich Basharin, Alexander Nikolaevich Safiulin), chosen as a prototype. This solution is characterized by the fact that it is a hookah bowl with rechargeable batteries built into the bowl, a bowl-shaped metal insert, a USB connector and wires connecting the batteries and the insert, as well as the USB connector and batteries. As a result, a simplification of the system for heating the smoking mixture in the hookah bowl without the use of coals and ease of operation of the hookah bowl were achieved.

However, in practice, during the operation of the prototype, it turned out that this solution does not provide sufficient uniformity of heating of the smoking mixture located in the bowl, and there is also a rather low speed and, in general, heating efficiency due to the fact that the heating surface area is limited by the inner surface of the metal insert, because of which only the lower part of the smoking mixture is heated in the first place and a significant part of the heat is lost through the open top of the bowl.

In connection with the above disadvantages of the prototype, the applicant came to the conclusion that it is necessary to add a heating element also on top of the hookah bowl above the metal insert to increase the heating efficiency of the smoking mixture while maintaining the autonomy of the bowl.

The purpose of this utility model is to eliminate these disadvantages of the prototype, namely, to increase the efficiency of heating the smoking mixture by improving the previously proposed design of the hookah bowl with a heated insert.

This goal is achieved by the fact that in the upper part of the hookah bowl claimed for registration, above the metal insert, there are interconnected heating element with ventilation holes and a battery.

Accordingly, the technical result of the proposed technical solution "Hookah bowl with a heated insert" is as follows.

The proposed improved design of the hookah bowl with a heated insert increases the heating efficiency of the smoking mixture located inside the metal insert due to the fact that the heating of the smoking mixture occurs uniformly simultaneously from above from the side of the heating element and from below from the side of the inner surface of the metal insert, and at the same time heating is carried out quite quickly, as the heat loss due to the presence of a heating element above the insert is minimized.

Also, the claimed utility model as a whole expands the arsenal of technical solutions for bowls for hookahs with a system for heating the smoking mixture without the use of coals.

The technical result is achieved in that the hookah bowl with a heated insert is characterized by the fact that it is a hookah bowl with batteries built into the bowl, an insert in the form of a metal bowl, a USB connector and connecting the batteries and the insert, as well as a USB connector and batteries with wires, characterized in that a heating element with ventilation holes and a battery connected to each other are located above the metal insert.

The claimed technical solution is illustrated by a schematic representation of the proposed hookah bowl with a heated insert (Fig. 1), explaining one of the embodiments of the proposed utility model in the framework of the claimed formula, where 1 is the hookah bowl itself, 2 is the bowl-shaped insert built into the bowl made of metal, 3 – rechargeable batteries, 4 – USB connector, 5 – wires connecting batteries and insert, as well as USB connector and batteries, 6 – heating element with ventilation holes 7, 8 – rechargeable battery.

To obtain a technical result, the utility model can be implemented in the following preferred way, which does not exclude other ways of implementation within the framework of the claimed formula of the utility model.

The proposed hookah bowl with a heated insert (1) is a classic hookah bowl (1) attached to the hookah shaft. In this case, the bowl can be made of clay, ceramic or any other material that is used for the manufacture of hookah bowls, does not heat up as a result of exposure to a heating element and does not conduct current. Heating systems located inside the metal insert (2) of the smoking mixture are carried out without the use of coals using electric current and are located simultaneously inside the bowl (1) and outside above the metal insert (2). The smoking mixture heating system, located inside the bowl (1), consists of a metal insert (2), rechargeable batteries (3), a USB connector (4) and wires connecting the batteries and the insert, as well as a USB connector and batteries (5 ). Another heating system consists of a heating element (6) located above the metal insert (2) with ventilation holes (7), above which a storage battery (8) connected to the heating element (6) is located. The heating element (6) can be connected to the storage battery (8), for example, with short rigid insulated wires (shown schematically in the figure). However, this does not exclude other ways of connecting the heating element (6) to the battery (8), including reusable ones that allow an unlimited number of disconnections and connections of the battery (8) to the heating element (6).

To prevent the battery (8) from heating itself from the heating element (6), an air gap shown in the diagram is formed between the heating element (6) and the battery (8).

The insert (2) is made in the form of a metal bowl. The heating element (6) may be a metal plate. Moreover, in both cases, the metal may have, among other things, a high resistivity, for example, it is made of alloys based on nickel, copper, manganese, and some other metals. High resistivity allows, on the one hand, to sharply reduce the current transmitted to the insert (2) from the batteries (3) through the wires (5) and to the heating element (6) from the battery (8), and, on the other hand , provide heating of the insert (2) and the heating element (6) to a limited temperature of 150 degrees Celsius. These properties make the use of the insert (2) and the heating element (6) safe, and the temperature of 150 degrees Celsius allows for uniform heating of the smoking mixture located on the metal insert (2), without overheating, rapid drying and the release of acrid tobacco smoke.

Due to the presence of the metal insert (2) and the heating element (6) heated under the action of the electric current emanating from the batteries (3) and (8), the smoking mixture located inside the metal insert (2) is heated simultaneously from below over the entire area of contact with the inner surface of the metal insert (2) and from above from the heat coming from the heating element (6). As a result, uniform heating of the smoking mixture is achieved. Also, due to simultaneous heating from above and below, heating of the smoking mixture is carried out quite quickly, which is also caused by minimization of heat loss due to the presence of a heating element (6) above the metal insert (2), almost completely covering the upper part of the metal insert (2). In this case, the ventilation holes (7) provide air exchange between the area inside and outside the metal insert (2). Thus, the proposed design of the hookah bowl provides an increase in the efficiency of heating the smoking mixture.

Rechargeable batteries (3) accumulate the current that comes in when they are connected with a USB cable (not shown in the image) to the mains through the USB connector (4) and wires (5). Through the wires (5) the electric current is supplied from the batteries (3) to the insert (2). After the process of recharging the batteries (3) is completed, they are disconnected from the power supply, the bowl (1) is connected to the hookah. The heating element (6) receives current from the storage battery (8), which can be both disposable and rechargeable, and, accordingly, it can be removed and replaced with a new battery, or connected to a power source for recharging.

Thus, the hookah together with the bowl (1) can be moved to any place, a permanent connection to the power supply is not required, since the charge of the batteries (3) and (8) is enough for 2 hours of operation, that is, 2 hours of current supply is provided from batteries (3) and (8) to insert (2) and heating element (6). As a result, the autonomy of the system for heating the smoking mixture in the proposed bowl with a heated insert (1) is still ensured, and, therefore, in general, the operation of the hookah without the need for constant connection of the batteries built into the bowl (1) and located above the metal insert (2) (3), (8) to the power supply.

The novelty of the presented utility model lies in the fact that the combination of its essential features provides an increase in the heating efficiency of the bowl of the smoking mixture located inside the metal insert and, in general, the expansion of the arsenal of technical solutions for bowls for hookahs with a smoking mixture heating system without the use of coals.

The proposed hookah bowl with a heated insert is currently being prepared for industrial production.
