发明人进一步发现，过量的有机酸会导致击喉感下降，但是会使较多尼古丁质子化，从而使尼古丁容易透过血脑屏障，提升满足感；较少量的有机酸会提升气溶胶中非质子化尼古丁的比例，提升使用者的击喉感和抽吸体验。因此，本申请电子烟液中的有机酸与尼古丁的摩尔比为约0.1:1至约2:1，在保证满足感的同时提升使用者的击喉感，使使用者在获得击喉感和满足感两方面平衡中获得最佳抽吸体验。The inventors further found that an excessive amount of organic acid can lead to a decrease in throat hitting sensation, but more nicotine will be protonated, so that nicotine can easily pass through the blood-brain barrier and improve the sense of satisfaction; a small amount of organic acid will increase the aerosol content. The proportion of non-protonated nicotine improves the user's throat hit and smoking experience. Therefore, the molar ratio of the organic acid and nicotine in the electronic cigarette liquid of the present application is about 0.1:1 to about 2:1, which can improve the user's throat hit feeling while ensuring the satisfaction, so that the user can obtain the throat hit feeling and The best suction experience is obtained in the balance of two aspects of satisfaction.
