Description

Heating element heating program regulating method and method for improving flue gas release uniformity

Technical Field

The invention relates to the technical field of heating devices, in particular to a heating element heating program regulating and controlling method and a method for improving flue gas release uniformity.

Background

Existing heated non-combustible smoke generating devices bake smoking articles through heating elements, which continuously generate smoke during smoking. Because the smoke volume of the smoking article can be obviously reduced after the smoking article is baked for a period of time, the smoke is released unevenly, and the smoking experience is influenced.

In the prior art, people can improve the heating temperature of the heating element in the later stage by experience in order to improve the smoke volume in the later stage of smoking, but the heating curve cannot be accurately determined by experience alone, the smoke volume in the later stage of smoking is controlled, particularly for different smoking articles, the suitable heating temperature is different from the realization, and the heating curve matched with different smoking articles cannot be accurately determined by experience alone.

The present invention has been made to solve the above problems.

Disclosure of Invention

The first aspect of the invention provides a heating element heating program regulating method, which heats a heating element by electric energy, divides the heating process of the heating element into two stages, namely a preheating stage and a pumping stage, and selects two parameter variables of time and temperature in each stage;

setting the heating temperature of the preheating stage as T1 and the heating duration as T1;

setting the heating temperature of the pumping stage to be T2 and the heating duration to be T2;

before suction, N is more than or equal to 1, if the smoke volume is small, namely the smoke concentration value is less than 1 mg/port, the smoke volume is less than 1 mg/port

Keeping the heating duration T1 unchanged, and increasing the heating temperature T1 by the value A; or keeping the heating temperature T1 unchanged, and prolonging the heating duration T1 by the value B;

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

Keeping the heating duration T1 unchanged, and reducing the heating temperature T1 by the value A; or keeping the heating temperature T1 unchanged, and shortening the heating duration T1 by the value B;

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

The temperature C value is reduced on the basis of the heating temperature T2 at the M-1 th port, and the temperature C value is reduced at the number of the suction ports at each subsequent time, or the temperature C value is reduced at each time of D values;

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.

The heating program and the heating curve of the invention can be programmed on the control element of the heating device after being determined, and the consumer can automatically adapt to the proper heating program when performing suction.

Compared with the prior art, the invention has the following beneficial effects:

1. the invention specifically determines a heating element heating program regulation and control method, wherein the heating element is heated by electric energy, the heating process of the heating element is divided into two stages, namely a preheating stage and a pumping stage, the preheating stage can be subdivided into a plurality of small stages for control, two parameter variables of time and temperature are selected in each stage, and the temperature and the time of each stage are regulated according to the air pumping taste by a control variable method, so that a proper heating curve is determined. 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.
