电子烟抽吸参数、电池功率、雾化剂配比对气溶胶中烟碱释放量的影响研究

Eff ects of vaping parameters, battery power and e-liquid composition on nicotine yield in electronic cigarette aerosol

为客观评价影响电子烟烟碱释放量的因素,采用电子烟综合测试平台研究电子烟抽吸参数、电池功率、雾化剂配比等条件对电子烟气溶胶中烟碱释放量的影响。结果表明:1)抽吸曲线、抽吸持续时间和抽吸容量是影响电子烟气溶胶烟碱释放量的主要因素,抽吸频率对电子烟气溶胶烟碱释放量影响的程度较小;2)在导油棉正常导油条件下,电子烟烟碱释放量随电子烟电池功率的增大而增加;3)对于雾化剂为丙二醇和丙三醇的电子烟,丙二醇的含量越高电子烟烟碱释放量越高。

In order to evaluate the factors that influence the nicotine yield of electronic cigarette, the comprehensive test platform was used to study the effects of vaping parameters, battery power, and e-liquid composition on the nicotine yield in electronic cigarette aerosol. Results showed that：1） The vaping profile,vaping duration, and vaping volume were main factors affecting the nicotine yield, while vaping frequency had little effects on nicotine yield; 2）Under the condition of the wick to work, the nicotine yield increased with the increase of battery power; 3） For the electronic cigarettes whose atomizing agent consisted of propylene glycol and glycerin, the nicotine yield increased with higher ratio of propylene glycol.
