  • Smoking appliances which firstly appeared in the countries of the East, known as hookahs, became extremely popular in recent years, and they are an alternative to ordinary cigarettes, particularly, among young adults.
  • Smoking appliances comprise a vessel partially filled with water or any other liquid medium. Suction through a tip creates a low air pressure in a vessel.
  • a smoke tube goes to the water level, its head part is located near an upper end, where tobacco is placed, which is heated by coal from an upper side. A mixture of air, vapor and smoke particles appears as a result of tobacco heating, then this mixture is inhaled by the smoker. It is obvious that the heat produced by combusting coal may lead to carbon monoxide poisoning, burns or, in extreme cases, even a fire.
  • hookahs As hookahs are filled manually, high-quality preparation of hookahs for the use is also not guaranteed. For this reason, hookahs, which are more common today, should only be used outdoors or in rooms with a guaranteed supply of fresh air.

  • Elimination of second openings in a bottom 12 of a cartridge 9 made it possible to reduce the ingress of liquid component of a medium 11 onto surface of a slot 8 many times over, which in turn reduces the need to clean a slot 8 . Absence of second openings in a cover 16 of a cartridge 9 reduces the possibility of vaporization from a medium 11 getting onto an upper heating element 19 (not shown in FIG. 7 ).
  • Thermoelectric element 28 is controlled using commands from a programmable controller 4 .

If an emergency occurs, for example, an inhalation appliance overturns, a command is sent to heating elements 19 and 20 to disconnect them from a power supply unit 3 . Together with the system of valves described above, this allows for making the safest possible device for inhaling aerosol.
  • an air exhaustion sensor (not shown in the drawing) may be installed, due to which it may be possible to quickly increase the power on a thermoelectric element 28 . Due to sharp increase in the temperature of the air passing through chamber 30 , it becomes possible to act with a thermal shock on the environment in a cartridge 9 .
  • thermoelectric element 28 Without receiving a signal from an exhaustion sensor, a thermoelectric element 28 switches to a temperature balance maintenance mode. This reduces the energy costs of a device and, as a result, increases battery life of a device. It also helps to reduce the consumption of a medium that releases particles of an active substance, since there is no burning of it, and to improve taste of the aerosol. Maximum temperature of a thermoelectric element 24 is selected for the types of specified medium for better disclosure of taste and reduction of harmful substances in the formed aerosol.
  • a novel original vaporization unit has been developed, implementing a novel, effective and safe method of heating a medium that releases an active substance.
  • Such unit ensures the production of a mixture of air, steam and particles of an active substance without combustion, as well as a novel effective and safe device for inhalation of a mixture of air, vapor and particles of an active substance without combustion using the vaporization unit.
