Description

Technical Field

[0001] The present invention belongs to the technical field of detecting smoke content of a filter element of an electronic cigarette, and in particular relates to a method for detecting smoke content of a filter element of an electronic cigarette. Background Art

[0002] As a product promoted as an alternative to cigarettes, e-cigarettes are widely welcomed by smokers, especially young consumers, due to their ability to significantly reduce harmful ingredients and their healthy, fashionable and personalized image. Coupled with people's demand for healthy living and the strengthening of anti-smoking efforts in various countries, the traditional tobacco market has stagnated, while the e-cigarette market has shown an upward trend.

[0003] Electronic cigarettes are mainly composed of four parts: e-liquid (containing nicotine, flavors, solvent propylene glycol, etc.), heating system, power supply and filter. They produce aerosols with specific smells through heating and atomization for smokers to use. The core part of e-cigarettes is the e-liquid. The main components of the e-liquid are food-grade or medical-grade propylene glycol (also known as glycerin), propylene glycol and polyethylene glycol, as well as tobacco-specific flavors. It also contains nicotine, which determines the taste of the e-cigarette.

[0004] In the prior art, the detection of the smoke content in the filter element of the electronic cigarette usually requires the use of precise equipment for precise detection, and it is impossible to judge the smoke based on the number of times the electronic cigarette is used. As a result, each time the corresponding data of the smoke content in the filter element of the electronic cigarette is needed, it is necessary to use equipment for extraction and precise measurement, which not only increases the cost of data acquisition, but also increases the time cost, and reduces the efficiency of acquiring the smoke content data in the filter element of the electronic cigarette.

[0005] Therefore, it is necessary to invent a method for detecting the smoke content of an electronic cigarette filter element to solve the above problems. The method can directly determine the smoke content of the filter element by the number of times the electronic cigarette filter element is used, thereby increasing the convenience of data acquisition.

Two electronic cigarettes are tested for smoke volume comparison, and the exhaust gas is collected, processed, and recorded; Step 3: Observe that the smoke volume reaches the requirement and the simulated artificial mouthpiece smokes 10 times, and guide the smoke generated by the remaining 4 electronic cigarettes to be absorbed by 5% nitric acid aqueous solution; Step 4: extract the collected electronic cigarette smoke with a 5% nitric acid aqueous solution, wherein two extracted solutions are directly analyzed by sp-ICP-MS equipment for heavy metal data Z1 in the electronic cigarette smoke; the other two extracted solutions are analyzed by gas chromatography to obtain nicotine content data Y1 in the electronic cigarette smoke. The gas chromatography analysis method is configured with an extractant and a nicotine standard series solution, and then performs oscillation extraction and gas chromatography analysis. The gas chromatography analysis method has high sensitivity, good selectivity, simple operation, and high repeatability, and is suitable for accurate quantitative analysis of nicotine in electronic cigarette smoke; Step 5: Repeat Step 1 to Step 4 to obtain multiple groups of heavy metal data Z (Z1, Z2…Z) in the smoke of new electronic cigarettes with 10 puffs per group. n ) and the nicotine content data Y (Y1, Y2…Y n ); Step 6: When Z n-2 =Z n-1 =Z n , and Y n-2 =Y n-1 =Y n When the electronic cigarette filter element absorbs saturated; Step 7: When Z n-2 >Z n-1 >Z n , and Y n-2 >Y n-1 >Y n When the electronic cigarette filter element is blocked, the detection is stopped; Step 8: The heavy metal data Z (Z1, Z2…Z n ) and the nicotine content data Y (Y1, Y2…Y n ) are archived in sequence, and the number of times the electronic cigarette is used and the corresponding data are displayed by installing a display mechanism on the electronic cigarette.
