The aerosol generating device is an electronic delivery device that delivers nicotine to the respiratory system by means of electronic heating. As a substitute for nicotine products, it has nicotine taste, but no ash, no cigarette end, no combustion, no open fire, and no harmful substances such as tar, carbon monoxide, hydrocyanic acid, acrolein, arsenic, lead, mercury, etc. In addition, the nicotine solution is atomized to form aerosol, and the aerosol is diluted rapidly in air without forming second hand smoke. The electronic aerosol generating device integrates modern microelectronic technology, biotechnology and healthy living concept, and attracts many eyeballs of consumers who want to abstain from nicotine in a short time.
Because of the numerous advantages of electronic aerosol generating devices, an increasing number of consumers are beginning to accept and use, and some of the disadvantages of electronic aerosol generating devices are also increasingly manifested. According to investigation, the current commercial electronic aerosol generating devices mostly use nicotine atomized liquid with better fluidity, but liquid leakage is easy to occur from the positions of the atomizer base, the joint of the oil bin and the base, the suction nozzle and the like. Although the structure of the atomizer is continuously improved by the existing manufacturer, a closed atomizer is developed, the problem of liquid leakage in the product transportation process is well solved by adopting a blocking type design of an airflow channel and a smoke liquid channel, once the product is used, the airflow channel and the smoke liquid channel are always communicated, the situation of liquid leakage still inevitably occurs in the later use process, the consumer generates bad sucking experience, the quality of an electronic aerosol generating device is directly influenced by the problems, and meanwhile, the development of the electronic aerosol generating device is restrained.

The Chinese patent application with the patent number of CN110150725A discloses solid atomized oil, a preparation method and application thereof, and the solid atomized oil is obtained by mixing a porous carrier, a thickening agent, a binder and an atomizing agent. However, most of the polysaccharide components and the thickener binder used in the solid atomized liquid prepared by the two techniques are macromolecular components, and the risk of core pasting is caused in the atomization process of the atomized liquid, so that bad consumption experience can be brought to consumers.
Meanwhile, some manufacturers prepare solid atomized oil products, and vitamin E esters are used as emulsifying agents for realizing solidification of the atomized oil, so that the homogenization problem of the electronic atomized oil, essence, perfume and atomizing agents is solved, but reports show that a large amount of substances which block lung tissue structures and are found in the lungs of some atomized electronic cigarette deaths are related to vitamin E esters which are additives in the electronic atomized oil.

In combination with the sensory evaluation of examples 1 and comparative examples 1 to 4 at the completion of the preparation of the solid atomized oil, and with reference to tables 5 and 6, it can be seen that comparative examples 1 to 4 show that when glycerin or sodium stearate is used in an amount lower than the preparation amount, the solid atomized oil is not easily solidified, and the solidification effect is better than that in the preparation amount, but the hardness is too great, and the liquefying effect after heating is poor, and the taste after atomization is greatly affected.
In combination with the sensory evaluation cases of example 1 and comparative examples 5 to 10 at the completion of the preparation, and in combination with tables 5 and 6, it can be seen that when the dissolution temperature is too low, sodium stearate is not easily dissolved, the solid atomized oil is not easily solidified, and when the dissolution temperature is too high, glycerin is polymerized, so that the taste of the solid atomized oil is affected; when the heat preservation temperature is too low, the fluidity of the solid atomized oil is poor, injection molding is difficult, and when the heat preservation temperature is too high, nicotine salt and essence are easily destroyed, so that the taste of the solid atomized oil is affected.
While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
