The disadvantage of this device is that when this heater is made of metal, the walls will become very hot, which can damage the electrical part of the device, and it will also be uncomfortable to hold it due to the rather high temperature of the walls.

The technical problem is the inconvenience in the operation of the device, the lack of safety in its use.

The technical result is an increase in convenience and safety when using the device, an increase in the efficiency of heating the hookah smoking mixture.

The technical result is achieved by the fact that a device for heating a tobacco-containing smoking mixture in a hookah bowl, including: a housing with a lid, a power supply unit and a control unit. Moreover, the housing is made in the form of a hollow cylindrical or prismatic body in the form of a glass with a perforated bottom, a divider and a heating element are located in the housing. In addition, the divider is made in the form of two flat ceramic parts forming a horizontal pancake (plate) with a central slot in which the heating element is located, while grooves are made in the lower or upper ceramic part for supplying power to the heating element, and under the pancake there is a flat plate with a slot corresponding to the pancake slot, in which a valve is fixed, made in the form of a thin rectangular plate. Also, at least one hole is made in the lower part of the side surface of the housing.

The heating element should preferably be supported by protrusions made in the slots of the lower and upper ceramic parts. In this case, the flat ceramic parts of the pancake are fastened with fasteners.

At least one hole made in the lower part of the side surface of the housing may be a horizontal slot.

The lid is attached to the body by means of threads or bolts and has a mesh-covered opening in the upper part.

The proposed device for heating a tobacco-containing smoking mixture, shown in Fig. 1-3 are made mainly of metal.

The device is assembled as follows, see fig. 2.

First, a horizontal pancake with a central slot is assembled. To do this, take the lower part of the ceramic pancake 5, put the heating element 4 into its slot. In this case, the wires 6, for supplying power to the heating element, are also placed in the corresponding grooves of the lower part of the ceramic pancake 5. The heating element 4, due to its low weight, can be held by wires ( the spiral is fixed in the ceramic plate) 6, but it is preferable that it rests on the protrusions in the slot in the lower part of the ceramic plate 5 and is also fixed by any means. Then take the upper part of the ceramic pancake 3, combine its slot and mounting holes with the slot and mounting holes of the lower part of the ceramic pancake 5 and connect them with fasteners (not shown in the figures).

At the same time, a horizontal plate with a central slot and with a heating element and a wire installed in it form a single replaceable module, which can subsequently be replaced by the user in case of failure of the heating element. With such a replacement, there will be no need to purchase a new device entirely. The replaceable module is replaced by removing the old horizontal plate with a central slot and replacing it with a new one, which makes it easy to repair the proposed device.

After that, on the lower part of the body 11, in the shaped recess formed by the side of the lower part of the body, a plate 7 with a rectangular slot in which the valve 8 is fixed is placed with fasteners 9. The valve is made in the form of a thin flexible rectangular plate, while the valve is in normal mode is always open, and when the hookah is blown, it will close and prevent the smoking gas mixture from entering the heating element. Next, a previously assembled horizontal pancake with a central slot is placed on the plate 7. In this case, the slots of the pancake and the plate 7 are aligned, and the wire 6 is placed in the corresponding groove of the lower part of the housing. After that, the housing cover 2 is installed with the upper grid 1, it can be fastened with fasteners, or simply screwed to the lower part of the housing 1 and tighten the pancake and platinum 7.

The housing in its lower end part contains through holes 10 made in the form of holes forming a ring, as well as a horizontal slot 12 made on the side surface of the housing in the lower part, under the plate 7 with the valve 8. The slot 12 provides the smoker with access to external air flows, what is the optimum temperature for smoking. In this case, the slot 12 can be replaced by a plurality of holes made on the side surface of the housing in the lower part. These slots and holes are made for high-quality mixing of air flows.

The device works as follows.

The proposed device is installed on the bowl of the hookah, so that the device completely covers the bowl of the hookah and is securely fixed, as shown in Fig. 1. Under the upper grid 1 of the housing cover 2 of the proposed device, at a distance from the hookah bowl containing the tobacco-containing smoking mixture, a heating element 4 is installed, made, for example, in the form of a nichrome thread folded into a spiral and fixed in a pancake divider. When the proposed device is turned on, the heating element 4 heats the tobacco-containing smoking mixture through the air diffuser formed by the elements 3, 5, 7, 8, and through the holes 10 and the side slot 12 in the lower part of the housing 11. The power of the heating element 4 is selected in such a way that the hookah mixture is heated in the range from 600 to 900 degrees. At the same time, air enters the heating element 4 through the grid 1 of the housing cover 2. The power adjustment knob and the associated power regulator (not shown in the figures) are performed in any convenient place, so that the heat does not spread to the electrical part of the device.

The proposed device can operate both from the mains, through the power supply, and from batteries 13 of the power supply, see Fig. one.
