Description

Technical field

The utility model relates to hookahs, namely to the designs of electric heating devices for smoking mixtures, in particular those containing tobacco, used in traditional and other hookahs.

State of the art

In traditional hookahs, when smoking, embers are usually used, located on the bowl to transfer heat to the smoking mixture and its evaporation, in particular, containing tobacco. However, the use of embers as a heat source in hookahs has a number of disadvantages. When coal is burned, high levels of carbon monoxide CO, metals and various carcinogens are released. When smoking hookah, the water does not filter many of the toxic chemicals that are released when the charcoal burns, exposing smokers to their effects. These substances increase the risk of various diseases. In addition, smoldering coal increases the amount of CO and carbon dioxide CO ₂ in the environment. Smoldering coal is accompanied by an unpleasant odor and is a fire hazard.

To eliminate the noted shortcomings, it is known from the prior art to use electric heaters of the smoking mixture in the hookah bowl instead of traditional coals.

A device for induction heating of a smoking mixture is known (US 10561172 B2, IPC A24F 1/30, publ. 02/18/2020), containing a chamber for a smoking mixture, a first heater in the lower part of the chamber, a second heater in the upper part of the chamber, an air inlet connected with a chamber and an air outlet connected to the chamber.

A heating device for heating tobacco products is known (RU 2676159 C1, IPC A24F 1/30, publ. 12/26/2018), including a heating element, a housing containing said heating element, as well as a control device, an autonomous power source associated with it, and the device control is configured to maintain a constant temperature range of the heating element.

A heating device is known (WO 2021054910 A1, IPC A24F 1/30, publ. 03/25/2021), having a heat transfer base into the hookah bowl for placing tobacco, and side walls that extend from said heat transfer base that surround the heating volume; also comprises a front opening provided on one of said side walls, and an electric heater having a resistive heater body that is inserted into the heating volume through said front opening, and a power transmission cable that is electrically connected to said heater body.

At the same time, in the internal cavity of the body in the form of a glass, by means of an axial screw and a corresponding holding element, the following are fixed in series installed on its bottom: the first coupling, a flat air divider, the second coupling, a heater, a fixing nut and a cover.

A device for heating a tobacco-containing smoking mixture in a bowl of a hookah is known (RU 2755459 C1, IPC A24F 1/30, publ. 09/16/2021), including a housing, a power supply and a control unit. The body is made in the form of a hollow cylindrical or prismatic body in the form of a glass with a perforated bottom. The heating element is located in the housing. The body also has a lid. In the inner cavity of the body having the shape of a glass, by means of a retaining element, an air divider is fixed, which is a round horizontal plate perforated in the center with the possibility of mixing air flows and located between the heater with a thermally insulating gasket and the bottom of the glass, and a heater with a thermally insulating gasket between them.

A disadvantage of the known designs of heaters is the insufficient formation of aerosol, as well as overheating and burning of smoking mixtures, and large temperature fluctuations in the heating element during its regulation, which worsens the heating and evaporation of the smoking mixture in the bowl.

The closest in technical essence to the claimed technical solution is, chosen as a prototype, a smoking mixture heating device (US 20210251283 A1, IPC A24F 1/30, publ. 08/19/2021), containing two electric heating elements connected to a power source and installed in the corps. The heating element is made in the form of a resistance band and includes a chimney that surrounds the resistance band, allowing heat to be removed, and a heat transfer plate that includes one or more protrusions to remove excess heat. The air passes through the top of the chimney and is heated by the resistance band. The heat transfer plate and hot air heat the smoking mixture in the hookah bowl.

A disadvantage of the known heater is the insufficient formation of aerosol when smoking a hookah. Known design provides optimal temperature conditions, but not effective aerosol formation.

Disclosure of the essence of the utility model

The technical problem to be solved by the device is to eliminate the listed disadvantages of the prototype.

The technical result is to increase the efficiency of aerosol formation when smoking a hookah, by reducing the humidity of the air entering the bowl of the hookah.

The technical result is achieved by the fact that the smoking mixture heater in the hookah bowl contains two electric heating elements connected to a power source and installed in the housing, according to the utility model, the housing is made of upper and lower parts connected by at least one tube and containing heating elements, while an additional heating element is installed at the air flow inlet to the upper part of the housing.

In particular cases of implementation of the utility model, an additional heating element is made in the form of a resistive spiral; each heating element has its own heating temperature, which is in the range of 100-800°C.

Brief description of the drawings

The utility model is illustrated by a drawing showing a section of a smoking mixture heater in a hookah bowl.

Implementation of the utility model

The smoking mixture heater in the hookah bowl contains a housing consisting of the upper 1 part, where the incoming air flow is heated, and the lower 2 part, intended for heating the bowl. Each of the parts 1, 2 has inlet 3, 4 and outlet 5, 6 purge holes. The outlet 5 purge holes of the upper part 1 of the housing are connected by tubes 7 with the inlet 4 purge holes of the lower part 2 of the housing. Tubes 7 can be made, for example, of ceramics. The upper part 1 of the housing is provided with a heating element with air channels 8 and an additional heating element 9, made, for example, in the form of a resistive coil. The heating element 8 is located in the middle of the upper part of the housing 1, and the heating element 9 is located at the inlet of the air flow into the upper part of the housing 1, i.e. contacts with the inlet purge holes 3. The lower part 2 of the housing is provided with an electric heating element 10 with air channels.

Upper 8, 9 and lower 10 heaters are equipped with a control unit. The body and heaters 8, 9 and 10 are made of a cylindrical shape, since the upper part of the hookah bowl usually has a cylindrical shape.

The device works as follows.

Before smoking a hookah, a smoking mixture heater is installed on a bowl filled with a smoking mixture. The heater is connected to a power source, for example, batteries or a 220V electrical outlet can be a power source. Using the control unit, the device is turned on by pressing the corresponding on / off button of the heating device. The range of values of the required temperature of the heating device is maintained by a control device that implements a given temperature control algorithm. The indication of the temperature value of the heating elements 8-10 is carried out, for example, by means of a diode backlight on the control unit, which also makes it possible to regulate the temperature of their heating.

The heating temperature of the heating elements 8-10 is different and is in the range of 100-800°C. The heating elements 8, 9 are designed for drying and heating the air flow, and the heating element 10 is for direct heating of the bowl with the smoking mixture. Upon reaching the heating elements 8-10 of the set temperature, they begin to light up and smoke a hookah.

When air is drawn in through the mouthpiece of the hookah, air at atmospheric temperature through the purge holes 3 enters the heating element 9, located at the air flow inlet to the upper part 1 of the body. The passage of the air flow through the heating element 9 makes it possible to reduce its humidity, and the air flow is prepared for subsequent heating. The dried air flow passes through the air channels of the heating element 8 and is heated.

Then, through holes 4, 5 and tubes 7, the heated air flow enters the lower part 2 of the heater housing. The heating element 10 heats the bowl. Part of the heated dried air flow enters the heating element 10, and then into the bowl, and the other part through the outlet purge holes 6, bypassing the heating element 10, enters the bowl with the smoking mixture.

Installing an additional heating element 10 at the inlet of the air flow into the upper part 1 of the housing and heating it to a predetermined temperature, makes it possible to reduce the humidity of the air entering the heater. When the heated and dried air flow passes through the smoking mixture, it is saturated with moisture in the smoking mixture and further condenses to the state of an aerosol when cooled in the hookah shaft and flask, which leads to the effective formation of an aerosol mixture when smoking a hookah.

Smoking hookah is carried out as follows. Air is drawn in through the mouthpiece of the hose and a vacuum occurs in the upper part of the hookah bulb. Due to the appearance of vacuum, air is sucked in through the device for heating the smoking mixture. From heaters 8-10, heated air enters the bowl and evaporates the smoking mixture in it. Then an aerosol (gas mixture-smoke) is formed in the hookah shaft, which is filtered by water or other liquid in the hookah flask, and enters its upper part, and from there into the mouthpiece.

The proposed design of the heater makes it possible to achieve effective formation of an aerosol when smoking a hookah by reducing the humidity of the air entering the bowl of the hookah by installing an additional heating element at the inlet to the heater.
