Description

Technical field

The present invention relates to heating devices and can be used to heat smoking mixtures, in particular those containing tobacco, in traditional 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, 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. Water does not filter many of the toxic chemicals that are released when charcoal burns, exposing smokers to their effects. These substances can 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.

Known electric heater for hookah (US 8983282 B2, publ. 03/17/2015) The heating element can be located inside the housing, which, in turn, can be placed above the bowl of the hookah. The housing has adjustable damping holes designed to allow air to pass through the heating element. The circuitry supplying the heating element may include a step-down transformer and a voltage adjustment switch. The heating device may be integral with the hookah or may be in the form of a separate component that may be installed over the bowl of the hookah.

A heating device for heating tobacco products is known (RU 2676159 C1, publ. 26.12.2018) 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 control device is configured to maintain a constant temperature range of the heating element.

A tobacco heater is known (US 10206424 B1, publ. 02/19/2019) containing one or more resistance bands for generating heat, which is transferred to the hookah bowl with the smoking mixture. The heater includes a chimney that surrounds a resistance band and provides heat dissipation, and a heat transfer plate that includes one or more ridges to dissipate excess heat. The air passes through the top of the chimney and is heated by the resistance band. The heated air is mixed with cold air drawn in through the ventilation space under the chimney and mixed air drawn in through one or more openings in the heating plate. The heat transfer plate and hot air heat the smoking mixture in the bowl.

A device for heating a tobacco-containing smoking mixture in a hookah bowl (RU 194302 U1, publ. 12/05/2019) is known, including a housing made in the form of a hollow cylindrical or prismatic body, in the upper part of which there is a power supply and control unit and a heating element. At the same time, the housing is made hollow in the form of a cylindrical or prismatic cap with the formation of external and internal casings, a power supply and control unit are located in the cavity of the housing. Through holes are made in the side wall of the outer casing along the perimeter, and the upper central part of the inner casing is perforated, while the heating element is fixed in the cavity formed by the inner casing above the heated tobacco-containing smoking mixture at some distance from the upper perforated wall of the inner casing.

A device for heating a tobacco-containing smoking mixture in a hookah bowl (RU198662 U1, publ. 07/21/2020) is known, including: a housing made in the form of a hollow cylindrical or prismatic body in the form of a glass, in the upper part of which there is a heating element, a power supply unit and a control unit. At the same time, in the inner 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 disadvantage of the known heaters is the insufficiently efficient heating of the tobacco-containing smoking mixture, the long heating of the bowl, since the smoking mixture heaters are used without preheating the incoming air, which leads to a long and insufficient heating of the bowl.

The closest in technical essence to the claimed technical solution is an induction heating device (US 10561172 B2, publ. 02/18/2020) containing a chamber for smoking mixture, the first heater in the lower part of the chamber, the second heater in the upper part of the chamber, an air inlet connected with a chamber and an air outlet connected to the chamber.

The disadvantages of the closest analogue include the design complexity of the heating device, which is a kind of oven for heating a special capsule with tobacco, as well as the impossibility of using it in traditional hookahs with a bowl for smoking mixture. In addition, when smoking a hookah, tobacco is located directly in the heater chamber, and after smoking tobacco with aromatic additives, the corresponding smell will remain in the chamber, which is difficult to get rid of, since washing with water and detergents of a heating device with electric elements is prohibited.

Disclosure of the essence of the invention

The technical problem to be solved by the device is to eliminate the listed shortcomings of the closest analogue.

The technical result is to increase the efficiency of heating the smoking mixture in the bowl of the hookah and control the temperature of its heating, which in turn increases the efficiency of the formation of the gas mixture in the hookah during smoking and optimizes the process of smoking the hookah.

The technical result is achieved by the fact that the device for heating the smoking mixture in the hookah bowl contains a body consisting of an upper part having at least one inlet and a lower part having at least one outlet, while between the parts of the body there is at least one purge hole, a heater in the upper part of the body, providing heating of the air entering the bowl, having at least one purge hole and a heater in the lower part of the body, located above the bowl with the smoking mixture and providing it heating, as well as a heater control unit connected to the power supply.

In particular cases of implementation of the invention, a cartridge-type heater is used as a heater in the upper part of the housing, and a flat-type heater is used as a heater in the lower part of the housing.

Brief description of the drawings

The invention is illustrated in the drawing. In FIG. shows a section of the smoking mixture heater on hookah bowls.

Implementation of the invention

The device for heating the smoking mixture in the bowl of the hookah contains a housing 1, consisting of the upper and lower parts. In the upper part of the housing there are inlet holes 2 and a heater 3 having vent holes 4 is located. In particular, the heater 3 may be a cartridge type heater. A heater 5 is provided at the bottom of the housing 1. In particular, the heater 5 may be a flat-type heater. Between the upper and lower parts of the housing there are purge holes 6 connecting the upper and lower cavities of the housing 1. In the lower part of the housing there are outlets 7. The upper 3 and lower 5 heaters are connected with a cable 8 to the control unit 9, which has buttons 11 for controlling the unit. The control unit 9 is connected to a power source. The connections of the upper part of the housing and the heater 3, as well as the two parts of the housing 1, are insulated with ceramic insulators 12.

In FIG. hookah 13 is also shown assembled with hose 14. And position 15 indicates a hookah bowl with smoking mixture 16.

The device works as follows.

The device for heating the smoking mixture is coaxially mounted on the bowl 15 filled with the smoking mixture 16 in a suitable manner. The control unit 9 is connected to a power source, for example, the power source can be an electrical network with a voltage of 220V. Using the control unit 9, the device is turned on by pressing the corresponding button on / off the device. The control unit transmits a signal to heaters 3 and 5, after which the heaters start to heat up. Maintaining the range of values of the required temperature of the heating device is carried out by a control device that implements a given temperature control algorithm. Indication of the temperature value of heaters 3 and 5 is carried out by means of diode illumination on the control unit 9, which also allows you to adjust the temperature of their heating.

After the bowl 15 with the smoking mixture 16 is quickly heated by two heaters and a vacuum appears in the hose 14, a gas mixture is formed in the hookah flask. Atmospheric temperature air enters through the inlet holes 2 in the upper part of the housing 1, passes through the purge holes 4 of the upper heater 3, due to which it heats up. The already heated air through the vent holes 6 between the parts of the body enters the lower part of the body, and then through the outlet holes 7 enters the bowl 15, and then into the hookah shaft 13. The upper heater 3 heats the air coming from the atmosphere, and the lower heater 5 heats bowls with smoking mixture. Air heating in the heater 3 and directly the heater 5 of the bowl allow you to quickly and deeply heat the bowl with the smoking mixture, and the control unit 9 provides the necessary temperature for heating the bowl with the smoking mixture while smoking the hookah.

Due to the proposed design of the smoking mixture heater in the hookah bowl, due to the presence of a lower heater for the bowl and an upper heater of the air entering the bowl, as well as a heater control unit, effective heating of the smoking mixture in the hookah bowl and, accordingly, effective formation of the gas mixture in the hookah are achieved, which allows optimizing hookah smoking process.
