Description

The proposed invention relates to 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, as well as 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 sources, 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 petal projections are located - 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. In the upper part of the body 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 lower end of the body in the form of a bottom and / or in the air gap between the body and the plate of the heating element is placed at least one heat-reflecting screen made of sheet heat-resistant material, fixed on rod holders.

The disadvantage of this heating device is 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 also be uncomfortable to hold it due to the sufficiently high temperature of the walls.

The technical problem is the inconvenience during the operation of the device, insufficient safety during its use.

A device for heating a tobacco-containing smoking mixture in a hookah bowl, including a body, a power supply and a control unit, is proposed. 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 body has a cover. An air divider and a heater with a heat-insulating gasket between them are fixed in the inner cavity of the cup-shaped body by means of a retaining element.

The retaining element can be, for example, fixing posts or corners.

In a particular case, the power supply and control unit are external.

In a particular case, the body is made of aluminum.

EFFECT: increased convenience and safety when using the device, increased 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, an air divider, a heater, and a thermal insulating gasket are fixed in the inner cavity of the glass-shaped body by means of fastening posts or a holding element corresponding to them (for example, corners, see Fig. 5).

In this case, the air divider, tightening nuts, a heater and a thermal insulating gasket form a single replaceable module, which can later be replaced by the user in the event of a heater failure. With such a replacement, there will be no need to purchase a new device entirely. The plug-in module is replaced by removing the old module from the mounting racks or supports and placing a new plug-in module on them.

The retaining element can be made in the form of fastening racks fixed with retaining couplings or nuts and nuts - latches, or angles fixed with screws and nuts.

For ease of use, the power supply and control unit should be external.

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

The essence of the claimed invention is illustrated by the drawings of FIG. 1-5, where

in fig. 1 shows a general view of the proposed device installed on a hookah,

in fig. 2 shows a general view of the proposed device, indicating the main parts;

in fig. 3 shows all the design elements of the proposed device,

in fig. 4 shows the proposed device with a power supply,

in fig. 5 shows a method of mounting the air divider on special supports (corners, instead of fixing posts).

The following elements are referenced in the figures:

1 - handle,

2 - silicone insulator,

3 - cover,

4 - fastening racks,

5 - a body in the form of a glass,

6 - heater,

7 - thermal insulating gasket,

8 - nut 1,

9 - nut 2,

10 - air divider,

11 - the bottom of the glass,

12 - heater supply cable,

13 - power supply unit,

14 - rechargeable battery,

15 - corners.

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.

In the fastening holes of the bottom of the glass 11, fastening posts 4 are inserted by means of a threaded connection. Then, an air divider 10, a heater 6, tightening nuts 8 and 9 and a thermal insulating gasket 7 are sequentially installed on the mounting posts through their mounting holes. The air divider 10 is a round horizontal plate perforated in the center for high-quality mixing of air flows. In this case, due to the special perforation of the cover 3, holes necessary for air supply are formed. After that, the resulting structure is fixed by a body in the form of a glass 5 and a cover 3, which is mounted over the cylindrical part of the glass 5 in any way. In this case, the supply cable of the heater 12 is led out through the body in the form of a cup 5, for example, through the side wall, as shown in Fig. 4, the power is supplied from the power supply unit 13.

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, a heater 6 is installed, made, for example, in the form of a nichrome thread folded into a spiral shape 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 air flows, and through the holes in the bottom of the glass 11, heats the tobacco-containing smoking mixture. The power of the heater 6 is selected in such a way that the hookah mixture is heated in the range from 50 to 200 degrees. In this case, air is supplied to the heater 6 through the perforation of the cover 3. 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 temperature of 700-900 degrees Celsius, and then the temperature gradually decreases to 600-700 degrees Celsius.

The proposed device can operate both from the electrical network, through the power supply 13, and from the rechargeable batteries 14 of the power supply 13.
