电子烟灵敏度与抽吸轻松度性能测定方法

摘要

The vaping sensibility and easiness of e-cigarettes (ECs) were analyzed by peristaltic pump and U-shaped water manometer.Results showed that initial flow rate parameters could directly reflect sensibility property.The less initial flow rate needed,the better sensibility performed.Different relation appeared between pressure drop and sensory ease feeling for different EC types.A positive correlation was proved for rechargeable type,while negative correlation for deposable ones.The difference was correlated with air hole area in EC device.These results also showed that difference in sensibility and ease feeling property existed in different specifications of EC,and in products of same specification.The homogeneity of E-cigarettes production needs to be improved.%利用蠕动泵和压力计的结合,以触发抽吸流量和抽吸真空度两项指标表征电子烟的灵敏度和抽吸轻松度性能.结果表明,触发抽吸流量可直接反映电子烟的灵敏度性能,触发抽吸流量越小,电子烟灵敏度越高.对于不同类型的电子烟,抽吸真空度与抽吸轻松度关系不同,整体式电子烟抽吸真空度与抽吸轻松度呈负相关,而分段式电子烟呈正相关.这与分段式电子烟的打孔稀释有关.此外,不同规格电子烟以及同一规格的产品之间均存在不同程度的差异.这表明,目前电子烟的加工均一性还有待改进和提高.
