Description

Technical Field

[0001] The present invention belongs to the technical field of heated cigarettes, and in particular relates to an intelligent temperature control module for heated cigarettes and an application thereof. Background Art

[0002] Traditional cigarettes release smoke by burning tobacco, a process that produces a large amount of harmful substances such as tar and carbon monoxide, causing significant harm to human health. With the tightening of global tobacco control policies and the improvement of consumer health awareness, heated cigarettes have gradually become an important innovation direction in the tobacco industry. Heated cigarettes precisely control the heating temperature (usually below 350°C) by heating tobacco devices, allowing nicotine and flavor substances in tobacco or cigarette cartridges to volatilize, while greatly reducing the generation of harmful substances. Existing heated cigarettes mainly achieve temperature control through fixed power output, which is affected by factors such as ambient temperature and cigarette cartridge status, resulting in fluctuations in the actual heating temperature, affecting the stability of smoke release and the consistency of taste.

[0003] CN117752132A discloses an adaptive temperature control method and device for a heated smoking device, the method comprising: S1, dividing the working temperature range into multiple temperature gears; S2, testing the heating curve of each temperature gear in the multiple temperature gears, and obtaining the gear heating curves of the multiple temperature gears; S3, detecting the real-time temperature value of the environment where the heated smoking device is located; S4, obtaining the gear heating curve corresponding to the real-time temperature value according to the temperature gear where the real-time temperature value is located, and heating the heated smoking device according to the gear heating curve. Before the heated cigarette smoking device starts heating, the ambient temperature is detected, the heating conditions are judged according to the corresponding temperature information, and different heating curves are matched according to different heating conditions, so that the ambient temperature can be standardized and customized without being affected by the external environment.

[0004] CN116982752A discloses a heat-not-burn smoking device and a heating control method and system thereof, which relate to the technical field of tobacco heating. The scheme of this application, after the heating component is assembled into the smoking device, by reading the label of the heating component, since one label corresponds to one type of cigarette, the read label is matched with the heating curve corresponding to the label in the preset information library, and finally, the heating component can be controlled to heat the cigarette using the matched heating curve. The scheme of this application, for cigarettes of different diameters, by selecting a heating component of corresponding size, and then matching the heating component with the battery box, the heating of the cigarette can be achieved.

[0005] Although the existing technology has developed a variety of heating modes or smoking devices that match different cigarettes, the above technology is still difficult to adapt to different cigarette sizes and materials, and cannot meet users' differentiated demands for taste. Therefore, the development of a more efficient and intelligent technology that adapts to different heated cigarettes is still an important issue facing the current tobacco industry. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an intelligent temperature control module for heating cigarettes and its application. The intelligent temperature control module disclosed in the present invention can be used for heating cigarettes.

[0072] Test Example 1

[0073] The heated cigarettes of Preparation Examples 1-3 were smoked on a smoking machine using the smoking articles of Examples 1-3 and Comparative Example 1 (the preheating time of the conventional smoking article was set to 20 seconds and the preheating temperature was set to 253° C.), and the aerosol of the first puff of the heated cigarette was captured according to the Canadian deep smoking mode (the puffing time was set to 3 seconds) (the total particulate matter deposited on the filter was captured by the Cambridge filter), and the total particulate matter was measured as shown in Table 1:

[0074] Table 1

[0075]

[0076] Test Example 2

[0077] The heated cigarettes of Preparation Examples 1-3 were smoked on a smoking machine using the smoking utensils of Examples 1-3 and Comparative Example 1, respectively. The temperature of the smoke at the outlet was measured using a thermocouple temperature measurement method according to the Canadian deep smoking mode (the smoking time was set to 3 seconds). The thermocouple was fixed 1 mm from the center of the outlet of the filter portion of the heated cigarette. The thermocouple was connected to a temperature data acquisition system to measure the temperature of the smoke at the outlet of the mouth end of the heated cigarette during smoking.

[0078] The results are shown in Table 2.

[0083] Test Example 3 Consumer sensory test:

[0084] 60 consumers who frequently use heated cigarettes were randomly selected and divided into 12 groups, with 5 people in each group. Groups 1-4 used the heated cigarettes of Examples 1-3 and Comparative Example 1 to smoke the heated cigarettes of Preparation Example 1, groups 5-8 used the heated cigarettes of Examples 1-3 and Comparative Example 1 to smoke the heated cigarettes of Preparation Example 2, and groups 9-12 used the heated cigarettes of Examples 1-3 and Comparative Example 1 to smoke the heated cigarettes of Preparation Example 3. Then, the consumers were asked to evaluate and score the temperature perception, taste, and aroma release of the smoke, using a 5-point system: 4.5 points and above, indicating very good, very satisfied; 4-4.5 points are good; 3-4 points are moderately acceptable; and 3 points or less are not good, unacceptable. The score of each group is the average of 5 people, and the results are shown in Table 3.
