Problems solved by technology

Since the smoke volume of smoking products will be significantly reduced after being baked and smoked for a period of time, the smoke will be released unevenly, which will affect the smoking experience
[0003] In the prior art, in order to increase the amount of smoke in the later stage of suction, people will increase the heating temperature of the heating element in the later stage based on experience. Tobacco products, the suitable heating temperature and realization are not the same, pure experience cannot accurately determine the matching heating curve of different smoking products

Embodiment 1

[0041] like figure 2 As shown, there are two stages of temperature in the preheating stage and the suction stage. The preheating stage is divided into two small stages s1 and s2. The durations of the two small stages s1 and s2 in the preheating stage are respectively When t1=10 seconds and t2=20 seconds, the duration of the preheating stage is 30 seconds. The temperatures corresponding to the times t1 and t2 in the preheating stage are temp1=350°C and temp2=340°C. If the smoke volume of the first 3 puffs of smoke is less than 1mg / puff, keep the time of the preheating stage unchanged, and increase the temperature of the preheating stage, that is, increase temp1 and temp2 by 10 °C, respectively, to obtain temp1=360 ℃, temp2=350℃; or the temperatures temp1 and temp2 in the preheating stage remain unchanged, the duration t1 of the temperature in the s1 stage in the preheating stage is set to 20 seconds, and the duration t2 of the temperature in the s2 stage is set to 10 seconds,...

Embodiment 2

[0045] like image 3 As shown, the debugging method in the preheating stage is the same as that in Example 1, the temperature temp3 in the suction stage is 340°C, the timing starts when the suction stage is entered, and the temperature temp3 in the suction stage is increased by 10°C when the time reaches 100 seconds (at this time the suction The temperature of the suction stage is 350 °C), and then the temperature of the suction stage obtained after the previous temperature increase is increased by 10 °C within 130 seconds of the working time of the suction stage (the temperature of the suction stage at this time is 360 °C) , and then at 160 seconds of the working time of the suction stage, the temperature of the suction stage obtained after the previous temperature increase was increased by 10 °C (the temperature of the suction stage at this time was 370 °C).

[0046] The present invention has been exemplarily described above. It should be noted that, without departing from t...

Embodiment 3

[0048] In this example, there are two stages of temperature in the preheating stage and the suction stage. The preheating stage is divided into two small stages s1 and s2. The durations of the two small stages s1 and s2 in the preheating stage are t1=10 respectively. seconds, t2=20 seconds, the duration of the preheating phase is 30 seconds. The temperatures corresponding to the times t1 and t2 in the preheating stage are temp1=360°C and temp2=350°C. The smoke volume of the first 3 puffs, the smoke concentration value is 3mg / puff, and the smoke volume is moderate, the heating temperature T2 will not be adjusted, and the heating duration is t2;

[0049] In the suction stage, the temperature temp3 = 350°C. When the 8th puff is puffed, the smoke concentration is 2 mg / puff, and the smoke volume is moderate. The heating temperature T2 is no longer adjusted, and the heating duration is t2.

Abstract

The invention discloses a method for regulating the heating program of a heating element and a method for improving the uniformity of flue gas release. The invention heats the heating element by electric energy, and divides the heating process of the heating element of the heating device into two stages, the preheating stage and the suction stage. The preheating stage can be subdivided into several small stages for control. Two parameter variables, time and temperature, are selected for each stage, and the temperature and time of each stage are adjusted according to the suction taste through the control variable method to determine a suitable heating curve. . Compared with adjusting the temperature and time of the heating process simply by experience, the adjusting method of the present invention is more accurate, and an appropriate heating curve can be accurately determined. Further, the adjustment method of the present invention is suitable for different smoking articles, avoiding the problem that empirical parameters are unavailable after replacing different smoking articles. The present invention can set different heating modes according to different smoking articles.

Description

technical field [0001] The invention relates to the technical field of heating devices, in particular to a method for regulating a heating program of a heating element and a method for improving the uniformity of flue gas release. Background technique [0002] The existing heat-not-burn smoke generating device bakes the smoking article through a heating element, and continuously generates smoke during smoking. Since the smoke volume of the smoking article is significantly reduced after being cured and smoked for a period of time, the smoke is released unevenly, which affects the smoking experience. [0003] In the prior art, in order to increase the amount of smoke in the later stage of puffing, people will increase the heating temperature of the heating element in the later stage based on experience, but it is impossible to accurately determine the heating curve and control the amount of fume in the later stage of puffing, especially for different hair types. For smoking p...
