Embodiment 1

[0034] Example 1: Take 19 samples of No. 1 electronic cigarette, use a linear smoking machine to smoke in ISO mode, and use a trap with one channel without electronic cigarettes as a blank sample for nicotine determination. According to the above method, the nicotine in the smoke release after 50 continuous puffs of electronic cigarettes was determined. The measurement results are as follows:

[0035] The content of nicotine in No. 1 e-cigarette smoke emissions:

[0036]

[0037] The atomization uniformity of the electronic cigarette atomizer is expressed in SD as 0.0036.

Embodiment 2

[0038]Example 2: 19 No. 2 electronic cigarette samples were taken and smoked in the ISO mode with a linear smoking machine, and the trap of one channel was not filled with electronic cigarettes as a blank sample for nicotine determination. According to the above method, the nicotine in the smoke release after 50 continuous puffs of electronic cigarettes was determined. The measurement results are as follows:

[0039] The content of nicotine in the smoke emission of No. 2 electronic cigarette:

[0040]

[0041] The atomization uniformity of the electronic cigarette atomizer is expressed in SD as 0.0141. The above uniformity test shows that the atomization uniformity of the No. 2 electronic cigarette atomizer is not as good as that of the No. 1 electronic cigarette atomizer. The performance of the atomizer can be improved, and corresponding adjustments can be made to improve the atomization uniformity .

Abstract

The invention relates to a method for detecting atomization homogeneity of an electronic cigarette atomizer. A linear smoking machine is adopted to smoke electronic cigarettes of the same specification and the same type in an ISO smoking mode, 44 mm Cambridge filters are used for trapping total particulate matter of smoke release matter after an electronic cigarette is smoked by 50 times continuously, an absorption bottle is connected between a catcher and a smoking needle cylinder, and 20 mL isopropyl alcohol extraction agents with 0.2-0.5 mg/mL n-heptadecane as internal standard substance is accurately added in the absorption bottle. After smoking, the absorption liquid in the absorption bottle is used for extracting nicotine in the Cambridge filters, and the gas chromatographic method is adopted to measure the nicotine content in the extraction agents according to the GB/T 23355-2009. The nicotine content in the smoke release matter of all electronic cigarette samples is calculated to obtain the SD, and the value of the SD responds the atomization homogeneity of the electronic cigarette atomizer in the batch. The method can quantitatively research the atomization homogeneity of the electronic cigarette atomizer, and is a practical and scientific method for estimation on the atomization homogeneity of the electronic cigarette atomizer.

Description

technical field [0001] The invention relates to a method for testing the atomization uniformity of an electronic cigarette nebulizer for the content of nicotine in smoke emissions. Background technique [0002] With the continuous development of the global tobacco control movement, in order to meet the needs of different consumers, various imitation cigarette products are emerging. E-cigarettes are a new type of tobacco product that has developed the fastest in recent years. Alkali, flavoring substances and other mixtures make people inhale nicotine in different doses. E-cigarettes are electronic delivery devices that deliver nicotine to the respiratory system by means of electronic heating. As a substitute for cigarettes, e-cigarettes are very similar in appearance to real cigarettes. It simulates the taste of cigarettes, but has no ash, no cigarette butts, no burning, no open flame, and no tar, carbon monoxide, hydrocyanic acid, acrolein, arsenic, lead, mercury and other...
