Embodiment 1-2

[0031] Select two commercially available e-cigarette products, code-named 1 and 2, respectively.

[0032] Smoking cycle simulator (SCS) was used to simulate smoking e-cigarette 1 and e-cigarette 2 respectively, and the aerosol smoke produced was analyzed by DMS500 fast particle size spectrometer. First set the instrument parameters of SCS and DMS500: the suction volume set by SCS is 55mL, the suction interval time is 30s, the temperature of the sampling head is 320K, the data acquisition frequency set by DMS is 10Hz, and the secondary dilution factor is 300 . Of course, other instrumental parameters suitable for the job can also be used. After the parameter setting is completed, the e-cigarettes are smoked, and each e-cigarette takes 10 puffs. The particle size distribution and number of aerosol particles in the smoke generated by the two electronic cigarettes were measured online in real time, and the aerosol flow rate C and detection time t were measured. After the measurem...

Abstract

The invention discloses a method for evaluating the amount of electronic cigarette smoke, the method comprising the following steps: (1) measuring step: smoking the electronic cigarette, measuring the particle size distribution and number of aerosol particles in the generated smoke; and measuring the aerosol Volumetric flow rate C and detection time t; (2) data processing: by the particle size distribution of described aerosol particle and the number divide out each graded diameter di of aerosol particle and calculate the average number concentration n of aerosol particle corresponding to each di; ( 3) Calculate the generated smoke volume according to the smoke volume calculation formula of the present invention.

Description

technical field [0001] The invention relates to a method for evaluating the smoke volume of electronic cigarettes. Background technique [0002] Electronic cigarettes are electronic delivery devices that use electronic heating means to deliver nicotine to the respiratory system. It uses electric heating to heat a liquid medium containing nicotine to generate smoke. Compared with traditional cigarettes, electronic cigarettes have the following advantages: 1. The aerosol of electronic cigarettes does not contain harmful components such as tar, CO, and HCN; 3. Electronic cigarettes have no combustion process, will not produce soot and cigarette butts, and have no fire hazards. This electronic cigarette, which integrates modern microelectronics technology, biotechnology, and the concept of healthy life, firmly grasps the psychological characteristics of consumers and has attracted the attention of many consumers in a short period of time. At present, the research on electronic...
