IMPLEMENTATION OF A UTILITY MODEL

Below, all components of the utility model are described in detail with reference to the drawings and reference numbers indicated therein for a more complete understanding of the scope and all technical aspects of the claimed technical solution by a specialist in the state of the art.

Fig. 1 shows a functional diagram of a device for heating a hookah bowl with a smoking mixture.

The housing 1 is a hollow cylindrical tube with a closed bottom and an open top, made of a heat-conducting material, mainly metals. For example, aluminum, duralumin or silumin can be used as the material for the housing 1. Slots are made on the surface and the lower closed part of the housing 1. The housing 1 is connected to the cover 4 and the cable channel 8. Also inside the housing 1 there are thermal pads 3, a heating radiator 2, heating elements 5, a thermocouple 6, a thermistor 7. The housing 1 is used to fasten the structural elements of the device for heating the hookah bowl with the smoking mixture, and also ensures the transfer of heat to the bowl, heating it, and ensures the removal of excess heat through surfaces that are not in contact with the bowl. The heating radiator 2 is a cylindrical element made of a heat-resistant material with the ability to remove heat. Orderly vertical holes are made through the heating radiator 2. Thermocouple 6 is fixed in the central opening, while heating elements 5 are placed next to thermocouple 6 on opposite sides. Heating radiator 2 is fixed inside housing 1 by pressing with thermal pads 3 from the upper and lower sides. Heating radiator 2 allows controlling the temperature inside housing 1, preventing overheating of the hookah bowl heating device with smoking mixture, and also ensures heating of air entering through openings in housing 1, necessary for heating smoking mixtures. Heat is transferred into the air space both from the surface of heating radiator 2 and inside the openings, in addition, heat is transferred through thermal pads 3 to housing 1.

Thermal spacers 3 are round structural elements, related by their overall dimensions to the hollow space in housing 1. They have a 90-degree cutout on the inner edge to hold and increase the coverage area of heating radiator 2. They are used to maintain the temperature difference between housing 1 and heating radiator 2, ensuring heat transfer at the point of contact to avoid overheating and maintain the optimum temperature inside housing 1.

Cover 4 is designed to close housing 1 from above and to lay wires of heating elements 5 and thermocouple 6 located in heating radiator 2 by placing in cable channel 8, and also covers heating elements 5 and thermistor 7 located in the bottom of housing 1, which allows to increase safety of using the device for heating a hookah bowl with smoking mixture by eliminating factors increasing the probability of occurrence of fire hazardous situations. It is fixed on housing 1, for example, by means of self-tapping screws, bolts or heat-resistant adhesive joint.

Heating elements 5 are ceramic heating elements of cylindrical shape. They are placed in openings inside the heating radiator 2. They are used to generate heat.

Thermocouple 6 is a temperature sensor selected from a list of products available on the market, placed in the central opening in heating radiator 2. It is connected by means of wires to temperature control device 9 and is intended for regulating the temperature of heating radiator 2 to specified parameters by transmitting information about the current temperature of heating radiator 2 to temperature control device 9.

Thermistor 7 is a temperature sensor selected from a list of products available on the market, placed in the bottom of housing 1. It is connected by wires to temperature control device 9 and is designed to regulate the temperature of housing 1 to specified parameters by transmitting information about the current temperature of housing 1 to temperature control device 9.

The cable channel 8 is part of the cover 4 and is an element designed to fit tightly to the body 1, for example, made of aluminum, duralumin or silumin. It is used to lay the wires of the heating elements 5 and the thermocouple 6 located in the heating radiator 2, and also covers the heating elements 5 and thermistor 7 located in the bottom of the body 1, which ensures the safety of the device for heating the hookah bowl with the smoking mixture during operation.

Temperature control device 9 is a device selected from a list of products available on the market, connected to the thermistor 7, thermocouple 6, heating elements 5. It is used to control the temperature, as well as to carry out adjustments by setting parameters for the operation of heating elements 5.

The operation of the utility model is carried out as follows.

The device for heating the hookah bowl with the smoking mixture is installed on the bowl with the tobacco mixture and is connected to the network via the power supply. The body 1 is heated by the heating radiator 2, which evenly distributes the heat received from the heating elements 5. The temperature is controlled by adjusting using the temperature control device 9, and the data on the current temperature is transmitted to the temperature control device 9 from the thermocouple 6 and thermistor 7.

In order to prevent excessive heating of the bowl with the tobacco mixture from the housing 1, the heating radiator 2 is secured using thermal spacers 3, which absorb part of the heat, and the surfaces that do not come into contact with the heating radiator 2 and the housing 1, conduct heat into the near-air space inside the housing 1. Heating the bowl due to contact with the housing 1 allows the taste qualities of the tobacco to be revealed more vividly, while the design of the device for heating the hookah bowl with the smoking mixture and the arrangement of the heating elements 5 inside the heating radiator 2 for uniform heat distribution, as well as securing the heating radiator 2 in the housing 1 using thermal spacers 3, prevents the ignition of the smoking mixture and increases the level of safety.

When inhaled, air enters the housing 1 through the upper side openings and heats up, passing through the openings in the heating radiator 2. After which the heated air enters the bowl with the tobacco mixture through the openings located in the bottom of the housing 1, passes through the mixture, heating it and causing the smoldering effect. Air circulates through the side lower and middle openings on the housing 1 and cools the housing 1 to avoid overheating of the bowl with the tobacco mixture. The cover 4 with the cable channel 8 is intended for closing the housing 1 from above and laying the wires of the heating elements 5 and the thermocouple 6 located in the heating radiator 2, and also covers the heating elements 5 and the thermistor 7 located in the bottom of the housing 1, which makes it possible to increase the safety of using the device for heating the hookah bowl with the smoking mixture by eliminating factors that increase the likelihood of fire hazards, such as tipping over the device by touching protruding wires or contact of the wires with the bowl during operation of the device for heating the hookah bowl with the smoking mixture.

Thus, the technical result in the form of an increase in the level of safety while ensuring user satisfaction from the taste sensations of tobacco smoke has been achieved.
