CONTROL METHOD FOR CONTINUOUS RELEASE OF SMOKE FROM A NON-BURNING HEATED TOBACCO PRODUCT Russian patent published in 2023 - IPC A24F47/00 

FIELD: tobacco industry.

SUBSTANCE: control method for the continuous release of smoke from a non-burning heated tobacco product based on electromagnetic induction heating technology, in which the material for induction heating of a heating device for heating a non-burning heated tobacco product is not directly connected to the circuit system, comprising the steps where: a non-burning heated tobacco product is heated by means of a heating device by a heating method including a preheating phase (I), a heat preservation phase (II), and a smoking phase (III), in which the heat preservation phase (II) and the smoking phase (III) are in an alternating cycle; wherein the heating device is turned on prior to smoking for a preheating phase (I) in which the heating device continuously generates thermal energy to rapidly heat the tobacco material until a suitable first puff of smoke is obtained; then, the output power of the heating device is immediately reduced to ensure that the heating device enters the heat preservation phase (II), in which the heating device only maintains the temperature of the tobacco material to ensure the critical state of tobacco material smoke release, so that when power is applied, the temperature of the tobacco material increases, thereby quickly releasing a sufficient amount of smoke; then, when the temperature sensor of the heating device determines that the temperature decrease rate of the induction heating material reaches the predetermined range, the heating device enters the smoking phase (III) in which the output power is momentarily increased to compensate for the decrease in temperature of the tobacco material caused by smoking and to quickly heat up the tobacco material to ensure the release of smoke; wherein the smoking phase duration (III) is a smoking duration value determined by the temperature sensor of the heating device, and the smoking phase (III) is controlled to be halted according to the smoking duration value; and according to the result of the temperature sensor of the heating device, the heating device is alternately in the heat preservation phase (II) or the smoking phase (III), otherwise, the heating device stops working.

EFFECT: providing control over the number of puffs while smoking.
