摘要：設計了一種具有電加熱霧化功能的卷煙抽吸裝置,該裝置由夾持卷煙煙支的夾持器和具有電子霧化功能的組件兩部分組成.該煙具利用所裝霧化器中霧化液及其霧化產生的霧化蒸氣與卷煙主流煙氣的作用達到降低煙氣有害成分的目的.為了考查該煙具的減害效果,選擇丙二醇和甘油為霧化液,將卷煙樣品插入裝有霧化器的煙具,在ISO標準抽吸模式下抽吸10種卷煙樣品和1種參比卷煙,檢測捕集到的主流煙氣中有害成分的釋放量并與相同抽吸模式下未加裝煙具的卷煙樣品分析結果進行對比.研究結果表明:使用煙具后卷煙主流煙氣焦油量均有所下降,平均每支煙的焦油降低幅度為3.04％ ～ 18.4％.,主流煙氣中煙堿釋放量整體也表現出明顯的降低趨勢,降低率達到了28.4％～48.1％,而水分整體呈現出升高的趨勢,升高率達到了31.2％～153.8％.使用該煙具后卷煙主流煙氣有害成分釋放量明顯降低,氨的降低率達到了54.4％ ～ 67.8％,巴豆醛的降低率達到了51.1％～ 65.6％,HCN的降低率達到了42.8％～ 58.9％,B[a]P的降低率達到了42.9％～ 58.4％,NNK的降低率達到了48.0％～ 73.7％,而苯酚幾乎被完全去除,減害效果顯著,且該裝置結構簡單、操作方便,是一種有別于傳統卷煙減害技術的新方法.該裝置還可以采用各種功能性霧化液實現增香、保潤等其它作用,未來可繼續對其應用進行深入研究.%A novel cigarette smoking device was designed by adopting electronic-heating atomizing technique to reduce harmful components in cigarette mainstream smoke.The device was composed of a cigarette holder and an electronic atomizinger.Liquid solution was atomized and mixed with cigarette mainstream smoke,and harm components were reduced via interaction of atomized aerosol and cigarette mainstream smoke.To investigate the harm reduction effect of the device,ten cigarette samples and one reference cigarette were inserted in the smoking device after the mixed solution of glycerol and propylene glycol was added to the atomizer,and smoked by a smoking machine under ISO smoking regime.Deliveries of harmful components in captured cigarette mainstream smoke were determined and compared with those from normal cigarettes.Results showed that by using smoking device,delivery of tar in cigarette mainstream smoke was reduced by 3.04％ ～ 18.4％,nicotine was reduced by 28.4％ ～ 48.1％;moisture was increased by 31.2％ ～ 153.8％;ammonia was reduced by 54.4％ ～ 67.8％;crotonaldehyde by 51.1％ ～ 65.6％,HCN by 42.8％ ～ 58.9％,B[a]P by 42.9％ ～ 58.4％,NNK by 48.0％ ～ 73.7％,and there was almost no phenol.The smoking device is simple in structure and easy to operation.It also features flavor enhancing and moisture retaining through adding various functional solutions.
