Description

Technical Field

[0001] The present invention relates to the research field of dynamic draw resistance changes in consumers' specific smoking behavior of cigarettes, and more specifically to a characterization method for recording the puff intensity in a single-puff specific smoking behavior, and is particularly suitable for characterizing the behavior of traditional cigarettes and new tobacco products (such as electronic cigarettes and heated cigarettes). Background Art

[0002] The occurrence of some major human diseases is closely related to smoking, and the impact of smoking on health is increasingly concerned by all sectors of society. Therefore, epidemiological surveys on smoking, especially surveys on smoking behavior, are of great reference significance for the study of smoking and health issues. Considering that cigarette smoke is a complex aerosol composed of gaseous, vaporous and solid substances, coupled with the different habitual smoking behaviors of smokers, it will cause corresponding changes in the state of tobacco combustion, which may also cause changes in the types and levels of inhaled chemical components. Therefore, obtaining the smoking behavior of smokers during the actual smoking process can not only understand the release of chemical substances in cigarette smoke under this smoking behavior, but also accurately and timely understand consumers' acceptance of various brands of cigarette products, smoking habits and preferences, which is of great guiding significance to the product development and brand marketing and launch of various tobacco industry companies.

[0003] At present, the puffing behavior of the general process is usually characterized by the puffing frequency, puffing capacity, puffing interval, and puffing time. The specific puffing behavior of a single puff is generally characterized by the puffing capacity, that is, the volume of smoke per puff - in the specific implementation process, the puffing capacity of the puffing process is obtained by integrating the pressure value generated during the puffing process at high speed and time. In fact, the puffing capacity is more suitable for characterizing the puffing behavior of the general process, but not very suitable for the puffing behavior of a single puff. This is because in the actual recording process of the specific puffing behavior of a single puff, there are very large differences in the puffing behaviors of different consumers - some consumers' puffing behavior is relatively fast and deep, and some consumers take a slow and shallow puffing process. If the puffing capacity is used to characterize the specific puffing behavior of a single puff, the final result may not be very different, but the difference in the specific puffing behavior of consumers is very large, the burning process of the cigarette during the puffing process is also very different, and the harmful substances produced are also very different. Therefore, the puffing capacity cannot truly reflect the specific puffing behavior of consumers. It is necessary to find and use a more suitable parameter to characterize the specific puffing behavior of consumers. Summary of the invention

[0004] The purpose of the present invention is to provide a characterization method for recording the puff intensity in a specific puff behavior of a single puff in view of the deficiencies in the above-mentioned prior art. The present invention can objectively, accurately, quickly and easily record and characterize the level of the puff intensity of a consumer in a specific puff behavior of a single puff, providing a new feasible characterization method for the specific puff behavior of a consumer, facilitating the study of the dynamic change of the puff resistance in the specific puff behavior of a consumer, and having the advantages of accuracy, high efficiency, easy operation, strong practicality and wide application range.

[0005] The purpose of the present invention can be achieved by the following technical measures:

[0006] A characterization method for recording the puff intensity in a specific puffing behavior of a single puff of the present invention is achieved by the following steps:

[0007] A. Obtaining the suction flow data: Obtaining the suction flow data of the consumer during the specific single-mouth suction behavior process by means of a suction behavior flow detection device and a suction data collector connected through a catheter;

[0008] B. Drawing a suction flow rate curve: The suction data processing system connected to the output end of the suction data collector by electrical connection can automatically draw a suction flow rate curve of the consumer in the specific single-puff suction behavior process according to the suction flow rate data transmitted by the suction data collector, and determine the maximum suction flow rate Hm in the suction flow rate curve;

[0009] C. Determine the effective suction flow He: determine the effective suction flow He by taking 90% of the maximum suction flow Hm;

[0010] D. Determine the puff rise time Tr: The time from the beginning of puffing to the effective puff flow rate He during the specific puffing behavior of the consumer is taken as the puff rise time;

[0011] E. Determine the effective suction time Te: the time from the end of the suction rise time Tr to the time when the suction flow rate drops to the effective suction flow rate He again in the suction flow rate curve is taken as the limited suction time Te;

[0012] F. Characterize the suction strength Ss: Substitute the formula Ss=He*Te / Tr to calculate the suction strength Ss.

[0013] The front and rear ends of the puffing behavior flow detection device of the present invention are symmetrically arranged clamping tubes and suction tubes, and a silicone sealing ring for fixing cigarette samples is embedded in the inner cavity of the clamping tube.

[0014] The design principle of the present invention is as follows:

[0015] The present invention can intuitively reflect the obvious difference in the specific puffing behavior of consumers by means of a more suitable parameter, namely, by collecting the pressure drop value of the cigarette in any specific puffing behavior of the consumer, integrating it, and expressing the change characteristics of the dynamic suction resistance during the cigarette puffing process according to the relationship between the pressure drop integral value and the puffing flow rate. More specifically, the puffing flow rate data is obtained, the puffing flow rate curve is drawn, the effective puffing flow rate He is determined, the puffing rise time Tr is determined, and the effective puffing time Te is determined, and finally the puffing intensity is calculated by inserting the formula Ss=He*Te / Tr. In this way, the present invention can objectively, accurately, quickly and easily record and characterize the level of the consumer's puffing intensity in the specific puffing behavior of a single puff, provide a new feasible characterization method for the specific puffing behavior of a single puff of the consumer, facilitate the study of the dynamic puffing resistance change of the consumer in the specific puffing behavior of the cigarette, and have the advantages of accuracy, efficiency, easy operation and strong practicality. The characterization method provided by the present invention is not only applicable to the behavior of traditional cigarettes, but also applicable to the behavior of new tobacco products (such as electronic cigarettes and heated cigarettes). The present invention also has the advantage of a wide range of applications.

[0016] The beneficial technical effects of the present invention are as follows:

[0017] The present invention can objectively, accurately, quickly and conveniently record and characterize the intensity of a consumer's puffing behavior in a single puff, providing a new feasible characterization method for the consumer's single puff behavior, facilitating the study of the dynamic changes in the consumer's puff resistance in the specific puffing behavior of a cigarette, and having the advantages of accuracy, high efficiency, easy operation, strong practicality and a wide range of applications.
