if the smoke amount is moderate, namely the smoke concentration value is between 1 and 4 mg/port, the heating temperature T1 is not adjusted any more, and the heating duration is T1;
the smoke gas amount of the M-th port is sucked, M is more than N, if the smoke gas amount is small, namely the smoke gas concentration value is less than 1 mg/port, the smoke gas concentration value is less than 1 mg/port
Increasing the temperature C value on the basis of the heating temperature T2 at the M-1 th port, and increasing the temperature C value at each subsequent suction port number or increasing the temperature C value at each interval D value time;
if the smoke gas amount is large, namely the smoke gas concentration value is more than 4 mg/mouth, the smoke gas concentration value is larger than 4 mg/mouth

if the smoke amount is moderate, namely the smoke concentration value is between 1 and 4 mg/port, the heating temperature T2 is not adjusted any more, and the heating duration is T2;
by adopting the regulation and control method, the proper flue gas amount in the preheating stage and the suction stage is ensured, and the regulation and control of the heating temperature of the heating element are completed.
In the suction process, if the whole smoke amount is smaller, namely the smoke concentration value is less than 1 mg/port, the heating duration time T1 and T2 are kept unchanged, and the heating temperature T1 and T2 are increased by the value A.
The smoke concentration value is measured by a special smoke concentration measuring device for the tobacco product, and the smoke concentration value is obtained by specifically referring to the applicant with the application number as follows: 201810049568.0, title of the invention: a device and a method for measuring the smoke concentration of tobacco products.
Preferably, the heating temperature in the preheating stage is T1 of 200-400 ℃, and the heating duration is T1 of 5-60 s; the heating temperature of the pumping stage is T2 of 180-400 ℃, and the heating duration is T2 of 60-360 s. And T1 is slightly larger than T2.
Preferably, N is 2 to 4, preferably 2.
Preferably, the value of A is 1 to 20; the B value is 1-60.
Preferably, the value of C is 1 to 20; the value of D is 1-300.
Preferably, the preheating stage can be divided into a plurality of small stages, and specific temperature and time are set for each small stage to be fine-tuned.
Preferably, the smoke gas quantity of the M-th port is sucked, M is larger than N, and if the smoke gas is scattered and not concentrated, the temperature in the preheating stage is reduced by a certain temperature; the smoke is scattered and not concentrated, namely, when a certain smoke comes out from the mouth, the smoke is not gathered and is relatively dispersed, so that the smoke is judged by a plurality of professional suction evaluation experts together, and the specific temperature reduction value can be adjusted according to the actual condition.
In the middle and later periods of suction, if the cavity feeling is generated in the suction and the temperature of the smoke becomes cool, the temperature in the preheating stage is properly reduced. The middle-later stage of smoking refers to the middle-later stage of smoking articles after half smoking, for example, if the number of smoking openings of a certain smoking article is set to 12, starting from the 7 th opening. In existing smoking articles, which typically enter the later middle of draw after 120s of preheating, the different smoking articles do not enter the later middle of draw at the same time.
Herein, the cavity feeling means that a large amount of air is mixed in the smoke sucked by the consumer, and the suction resistance is reduced, even more, the smoke is not the air, and the index is judged by multiple professional suction evaluation experts together.
The temperature of the smoke entering the mouth of the consumer is usually 37-40 ℃, and the consumer feels that the temperature of the smoke is moderate and the smoking feeling is better. If the temperature of the smoke entering the mouth of the consumer is below 37℃ and the mouth of the consumer feels cool, the smoke is considered to be cool.
The heating process of the heating element is adjusted by the heating element heating program regulating method in the first aspect of the invention, and the moderate flue gas amount in the preheating stage and the suction stage is ensured, so that the uniform flue gas release in the whole suction process is realized, and the flue gas release uniformity is improved.

Compared with the method for adjusting the temperature and the time in the heating process simply by experience, the adjusting method is more accurate, and the proper heating curve can be accurately determined.
2. The adjusting method is suitable for different smoking articles, and the problem that experience parameters are unavailable after different smoking articles are replaced is solved. The invention may be provided with different heating modes depending on the smoking article.
