Description

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

State of the art.

Known heating device for heating tobacco products, see RF patent No. 2676159 from 26.12.2018. This heating device contains at least one heating element, a housing containing said at least one heating element, and a control device associated with it, at least one autonomous power source, and the control device is configured ensure the maintenance of the constant temperature range of at least one heating element. The disadvantage of this heating device is the complexity of the design and low reliability, due to the need to carry out forced cooling of the electrical part.

The closest technical solution is a device for heating a tobacco-containing smoking mixture in a hookah bowl, described in Russian patent No. 2685870, dated 23.04.2019. This patent discloses a device for heating a tobacco-containing smoking mixture in a hookah bowl, comprising a housing with a heating element. In this case, the body is made in the form of a hollow cylindrical or prismatic body, on the lateral surface of which, along the perimeter from the outside, there are cylindrical compartments - cells for autonomous power supplies, the longitudinal axis of which is parallel to the longitudinal axis of the body, and is equipped with a chamomile-shaped cover, along the perimeter of which there are petal projections - covers for the corresponding compartments. The heating element is made in the form of a plate made of a material with high thermal conductivity with through holes, attached to the lower part of the housing by means of rod holders with the formation of an air gap, in the body of which there are internal radial cavities in which electric heaters are installed. And in the upper part of the case there is a power and control unit, to which the electrical contacts of the compartments for autonomous power supplies and one or more evenly spaced electric heaters are connected, in addition, a heat-insulating plate is attached to the bottom end of the case in the form of a bottom and / or in an air the gap between the casing and the plate of the heating element is provided with at least one heat-reflecting screen made of sheet heat-resistant material, fixed on rod holders.

The disadvantage of this heating device is its low reliability due to the fact that due to its design features it can be made of plastic. During the manufacture of this metal heater, the walls will be very hot, which can lead to damage to the electrical part of the device, and it will not be comfortable to hold it due to the sufficiently high temperature of the walls.

The technical result of the utility model is to increase the safety and efficiency of heating the hookah smoking mixture.

The technical result is achieved in that the device for heating the tobacco-containing smoking mixture in the hookah bowl includes: a body made in the form of a hollow cylindrical or prismatic body in the form of a glass with a perforated bottom, in the upper part of which there is a heating element, a power supply unit and a control unit. In this case, in the inner cavity of the cup-shaped body, by means of an axial screw and a corresponding retaining element, the following are sequentially mounted on its bottom: the first sleeve, the flat air divider, the second sleeve, the heater, the lock nut and the cover.

The retaining element can be made in the form of a nut or in the form.

The power supply and control unit is supposed to be external.

Also, to improve heat transfer, the housing is preferably made of aluminum.

The essence of the claimed invention is illustrated by drawings Fig. 1-4, where

The proposed device for heating a tobacco-containing smoking mixture shown in FIGS. 1-5 is made mainly of metal.

The device is assembled as follows, see Fig. 3.

An axial screw 4 is inserted into the central hole of the cover 3. After that, the cover 3 is fixed by means of a threaded connection with a lock nut 8 to the head of the axial screw 4. Then, a heater 6, a coupling 9, an air divider 10 and a coupling are installed in the screw sequentially through their central holes 9. Air divider 10 is a round horizontal plate, perforated with holes for high-quality mixing of air flows. In this case, due to the retaining nut 8, a gap is formed between the cover 3 and the rim of the heater 7, which is necessary for air supply. The gap can be changed and adjusted by screwing the cover 3 with the nut 8 onto the axial screw 4 (gap reduction) see Fig. 5. Or unwinding (increasing the gap). Or, the gap can be changed by using the lock nut 8 and the ring (not shown in the figures). After that, the resulting structure is fixed by a body in the form of a glass 5, by means of a lock nut 11, which is integrated in any way into the bottom of the glass 12. In this case, the supply cable of the heater 13 is led out through the body in the form of a glass 5, for example, through the side wall, as shown in figure 4 and powered by power supply 14.

The device works as follows.

For the silicone insulator 2 of the handle 1, the proposed device is installed on the hookah bowl, so that the proposed device completely covers the hookah bowl and is securely fixed, as shown in Fig. 1. Under the top cover 3 of the proposed device, at a distance from the hookah bowl containing the tobacco-containing smoking mixture, there is a heater 6 made, for example, in the form of a nichrome thread folded into a spiral in a hollow frame and fixed in the body in the form of a glass 5. When the proposed device is turned on , the heater 6 through the air divider 10, which is necessary for high-quality mixing of the air flows, and through the holes in the bottom of the glass 12, heats the tobacco-containing smoking mixture. The power of the heater 6 and the height of the couplings 9 are selected in such a way that the hookah mixture is heated in the range from 200 to 500 degrees. In this case, air is supplied to the heater 6 from the gap between the cover 3 and the glass 5. The power adjustment knob and the associated power regulator (not shown in the figures) are made in any convenient place so that the heating does not spread to the electrical part of the device.

In addition, the device may contain a temperature sensor (not shown in the figures), located in the area of the location of the hookah smoking mixture. In the presence of a temperature sensor, the heater power is adjusted by the control unit automatically in accordance with the preset heating program of the control unit, for example, first, the coil is heated to a maximum temperature of 400-500 degrees Celsius, and then the temperature gradually decreases to 200 degrees Celsius.

The proposed device can operate both from the electrical network, through the power supply unit 14, and from the rechargeable batteries 15 of the power supply unit 14.
