Background technique

As a consumer product, tobacco is very popular among smokers, but nicotine, coal tar, benzopyrene and other components produced during the heating and combustion of tobacco seriously endanger human health. For this reason, electronic cigarettes have emerged on the market as tobacco substitutes. In addition, sick children are usually very resistant to taking medicine. For this reason, other ingredients are often added to children's medicines to improve the taste. However, feeding medicines to children is still a headache for parents. At present, some nebulizers have been developed in the market to release medicines by nebulization The active ingredient is used to treat children's diseases by inhalation.

There are two main types of drug atomization devices and tobacco atomization devices. One is to use artificially synthesized smoke liquid or liquid medicine instead of tobacco drugs, and use special devices to heat, vaporize and atomize before inhaling. The other is to use electronic devices to heat tobacco. Smoking raw materials or drug raw materials after fuming. The e-liquid or medicinal liquid used in the former is an artificial compound with a clear chemical composition. Its preparation requires complex chemical treatment. The production and processing process will consume a lot of energy and generate more hazardous waste. The cost is high, and the taste of the e-liquid is far less than The original tobacco is rich, and the medicinal effect of the liquid medicine is not as good as that of traditional Chinese herbal medicine. The latter directly uses tobacco raw materials or medicinal raw materials, and the taste and efficacy of tobacco are better. However, the tobacco raw materials and medicinal raw materials are heated and smoked for a long time, which is prone to uneven and insufficient heat transfer, resulting in the inability to fully release the active ingredients. .
