A charging procedure is aimed at high boiling point edible and tobacco flavor or edible and tobacco flavor containing waxiness, the edible and tobacco flavor is mixed with propylene glycol or propylene glycol/glycerin, and then molecular distillation is performed to obtain an electronic smoke solution base stock. The perfuming procedure is aimed at essential oil kind and low boiling point chemical synthesis perfumes and edible and tobacco flavors blended by the two kinds of perfumes. Through adding perfumes and natural nicotine in the base stock, an electronic cigarette smoke solution product is obtained. In the method, charging and perfuming are processed respectively, high boiling point and waxy components in the perfumes are removed, and defects that high boiling point perfumes easily generate charring smell, and electronic cigarette smoke solution is clear and bright and fragrance transmission property is better.
