Description

The proposed 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 level of technology.

Known heating device for heating tobacco products, see RF patent No. 2676159 from 12/26/2018. This heating device comprises 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 to to ensure that the temperature range of the at least one heating element is constant. The disadvantage of this heating device is the design complexity 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, 04/23/2019. 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 casing 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 casing, and is equipped with a camomile lid with petal protrusions located around its perimeter - lids for the respective cell compartments. The heating element is made in the form of a plate of 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 cell compartments for autonomous power sources and one or more evenly located electric heaters are connected, in addition, a heat insulating plate and / or in the air is attached to the lower end of the case At least one heat-reflecting screen of heat-resistant sheet material is fixed to the gap between the housing and the plate of the heating element, mounted on rod holders.

The disadvantage of this device for heating is low reliability due to the fact that due to the design features it can be made of plastic. In the manufacture of this heater from metal, 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 due to the rather high temperature of the walls.

The technical result of the utility model is to increase the safety and efficiency of heating a 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 housing, in the upper part of which there is a power and control unit and a heating element. In this case, the housing is made hollow in the form of a cap with the formation of the outer and inner casings, and in the cavity of the housing are the power supply and control unit. Through holes are made in the side wall of the outer casing around the perimeter, the upper central part of the inner casing is perforated. Also, coaxial threaded holes are made in the upper central parts of the outer and inner casings, in which a rod is located, rigidly connected to the housing of the heating element located in the cavity formed by the inner casing above the heated tobacco-containing smoking mixture at a certain distance from the upper perforated wall of the inner casing. The rod also has a handle, with the help of which the heater body is vertically moved relative to the heated tobacco-containing smoking mixture.

The cap is preferably made in the form of a cylindrical or prismatic body.

The power and control unit can be made in the form of a power regulator powered by an electric network.

The power and control unit can be made in the form of a power regulator powered by a battery located in the upper central cavity of the housing between the perforated inner part of the housing and the outer part.

Also, the device must additionally include a temperature sensor associated with the power supply and control unit, while the temperature sensor is installed at the level of the heated tobacco-containing smoking mixture.

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

figure 1 shows the proposed device mounted on a hookah, indicating the main parts;

figure 2 shows a view of the proposed device with side holes;

figure 3 shows a diagram of the electrical part of the device,

figure 4 shows the proposed device in section with an explanation of the adjustment of the heating element relative to the smoking mixture.

In the figures, the positions indicate the following positions.

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

The device operates as follows.

By the handle of the device 8, the proposed device is installed on the hookah shaft 1, so that the proposed device completely covers the hookah bowl 2. Moreover, the body (not shown in the figures) of the proposed device is a design of the external 3 and internal 4 cylindrical (can be conical) casings interconnected by a rod (shown in figure 4, the position is not indicated). The inner casing 4 of the proposed device has a perforation located above the hookah bowl 2 with the smoking mixture. Under the Central perforated part of the inner casing 4 of the device at an adjustable distance from the hookah bowl containing the tobacco-containing smoking mixture, a heater 5 is installed, made, for example, in the form of a nichrome thread folded into a spiral shape in a hollow frame, and mounted on legs on the inner casing 4 The adjustment of the heater 5 relative to the bowl of the hookah 2 (see figure 4) is carried out within 0.5-10 cm by rotation of the rod, rigidly connected with the housing of the heater. Thus, the rod together with the heating element moves vertically in the threaded holes of the hollow body of the proposed device. When you turn on the proposed device with the adjustment knob 7, the heater 5 begins to heat the tobacco-containing hookah smoking mixture in the range from 200 to 500 degrees, while the heater receives air from the holes of the side walls of the outer casing 3 (see figure 2) and perforation of the Central part of the inner casing 4.

The adjustment knob 7 and the associated power regulator 8 are carried out in any convenient place of the hood, so that the adjustment knob 7 is located on the outer casing 3, and the power regulator 8 is located in the inner space of the hood.

In addition, the device may include a temperature sensor (not shown in the figure) located on the walls of the inner casing, in the region of the location of the hookah smoking mixture. In the presence of a temperature sensor, the heater power is automatically adjusted in accordance with the specified heating program, for example, the tobacco mixture is first heated to a maximum of 400-500 degrees Celsius, and then gradually decreases to 200 degrees Celsius.

The proposed device can operate both from an electrical network and from batteries, as shown in Fig.3.
