Description

The utility model relates to structural elements of hookahs and can be used to increase the efficiency of formation of a smoking gas mixture in a hookah.

The prior art device for heating a tobacco-containing smoking mixture in a hookah bowl, comprising a housing with a non-combustible type heating element, for example, in the form of a graphite electrode or an electric lamp, connected by wires to an electric network (RU 2645568 C1, A24F 1/30, publ. 21.02 .2018; RU 140206 Ul, A24F 1/30, 2014). A significant disadvantage of the known solution is the schematic disclosure of the main structural features, and the use of a graphite electrode or electric lamp as a heating element does not provide efficient heating of the tobacco-containing smoking mixture placed in a hookah bowl.

The technical result, to which the utility model is directed, is to increase the heating efficiency of the tobacco-containing smoking mixture in a hookah bowl, and, accordingly, to increase the efficiency of forming a smoking gas mixture in a hookah.

The solution of this problem and the achievement of the claimed technical result is ensured by the fact that in the device for heating tobacco-containing smoking mixture in a hookah bowl containing a housing with a heating element, according to a utility model, the housing is made in the form of a hollow cylindrical or prismatic body, on the side surface of which around the perimeter on the outside there are cylindrical compartments - cells for autonomous power supplies, the longitudinal axis of which is parallel to the longitudinal axis of the housing, and is equipped with an ash-shaped lid, along the perimeter of which there are petal protrusions - lids for the corresponding compartments - cells, and the heating element is made in the form of a perforated plate of material with high thermal conductivity with through holes, attached to the lower part of the housing through rod holders with the formation of an air gap in the body of which internal radial cavities are made in which at least one electric heater is installed, while a power supply and control unit are located in the housing the line to which the electrical contacts of the compartments - cells for autonomous power sources and an electric heater are connected.

In addition, a temperature sensor is installed on the heating element connected to the power and control unit.

Preferably, the housing of the claimed device and the camomile cover are made of heat-resistant plastic.

The claimed implementation of the device for heating tobacco-containing smoking mixture in a hookah bowl in the form of a tubular body, on the lateral surface of which on the perimeter from the outside there are cylindrical compartments for autonomous power sources, and the presence of a heating element in the form of a perforated plate of a material with high thermal conductivity with through holes attached from the bottom to the housing with the formation of an air gap, in the body of which at least one compact electric heater is installed, preferably, with a conductive thread (or several evenly spaced electric heaters) and a temperature sensor connected to the power and control unit, with structural simplicity, it provides effective heating of the tobacco-containing smoking mixture and maintaining a predetermined constant temperature without overheating in the hookah bowl, and, accordingly, increasing the efficiency the formation of a smoking gas mixture in a hookah. Moreover, the presence of an air gap between the housing and the heating element and the execution of the housing made of heat-resistant plastic eliminates skin burns when touching the plastic housing. In addition, the use of replaceable power supplies, housed in the case, for example, finger-type galvanic cells (batteries) or rechargeable GP batteries, provides compactness, safety, reliability and ease of use of the hookah as a whole.

In FIG. 1 shows a general view of a device for heating a tobacco-containing smoking mixture in a hookah bowl; in FIG. 2 is a plan view of FIG. one.

A device for heating a tobacco-containing smoking mixture in a hookah bowl includes a housing 1 made of heat-resistant plastic (for example, from ABS plastic, SBS plastic, PLA plastic, HIPS plastic, PC plastic, PMMA, nylon, polycarbonate, etc. material) in the form of a tubular hollow cylindrical or prismatic body, on the side surface of which along the perimeter from the outside there are compartments — cells 2 with electrical contacts for autonomous power sources (not shown in the drawing), and a heating element made in the form a perforated plate 3 of a material with high thermal conductivity (for example, copper, bronze, brass, aluminum, steel) with through longitudinal holes 4 attached to the lower part of the housing 1 via rod holders 5 with the formation of an air gap 6, in the body of which is installed, at least one compact electric heater 7, preferably with a conductive filament, for example, a cartridge tube heater (or several evenly spaced electric heaters) and a temperature sensor 8. The housing 1 of the device is equipped with a camomile cover 9 with latches 10 and with holes 11 in the central zone, also made, preferably, of heat-resistant plastic, along the perimeter of which there are petal protrusions - covers 12, which cover the corresponding compartments - cells 2. In the upper part of the housing 1 is placed power and control unit 13, to which the electrical contacts of the compartments - cells 2 for autonomous power supplies, an electric heater 7 (or electric heaters) and a temperature sensor 8 are connected.

In this case, the compartments - cells 2 of the housing 1 are made with internal cylindrical cavities for installing finger-type power supplies (not shown in the drawing), for example, galvanic cells (batteries) or rechargeable GP batteries.

To reduce the heating of the housing 1 and heat loss, a heat-insulating plate 14 made of a material with low thermal conductivity can be attached to the lower end of the housing 1. The presence of holes 11 in the Central zone of the camomile cover 9 improves the air cooling of the housing 1 due to natural convection, which also reduces its heating.

The claimed device for heating a tobacco-containing smoking mixture in a hookah bowl works as follows.

Finger-type power sources are inserted into the compartments - cells 2 of the housing 1 and the claimed device is installed with the heating element plate 3 directly on the hookah bowl 15, seasoned with a tobacco-containing smoking mixture. By means of the power supply and control unit 13, an electric heater 7 (electric heaters) is turned on and the required temperature mode of heating is set, for example, adjustable in the range 350-650 ° C., which is controlled by a temperature sensor 8 mounted on the plate 3 of the heating element and displayed on the LED digital indicator - scoreboard (not shown in the drawing). In this case, the air from the environment, passing through the through holes 4 in the perforated plate 3 of the heating element made of a material with high thermal conductivity, is heated and enters the bowl 15 with a tobacco-containing smoking mixture, during which drying smoke is formed and the smoking process begins. The absence of wires for connecting to a power source ensures compactness, safety, reliability and ease of use of the hookah and expands the functionality of the hookah as a whole.
