The tobacco medium 260 may be stored in the chamber 211 in a state immersed in the moisturizing agent 261 . Tobacco medium 260 may be formed, for example, in a spherical shape, but is not limited thereto, and may also be formed in a polyhedral shape.

Also, the aerosol generating material is stored in the chamber 211 until the aerosol generating device 1000 is used. Accordingly, to prevent the tobacco medium 260 from reacting with the humectant 261 and/or the liquid composition, the tobacco medium 260 may include a protective coating adapted to the characteristics of the humectant 261 and/or the liquid composition.

As an example, the moisturizing agent 261 may include oil, and when the moisturizing agent 261 includes oil, the solid tobacco medium 260 may include an oil-proof coating formed on the outside. Accordingly, it is possible to prevent the moisturizing agent 261 containing the oil and the tobacco medium 260 from reacting with each other.

As another example, the wax-type moisturizer 261 is a substance that exists as a solid at room temperature, such as coconut oil or natural beeswax, for example, a moisturizer containing at least one of glycerin and propylene glycol, and a liquid containing a flavor component. Formed, the moisturizing agent 261 in the form of a wax may wrap the tobacco medium 260 in the form of a solid body.

The amount of the solid tobacco medium 260 may be adjusted in a mass ratio or volume ratio to the moisturizing agent 261 according to the user's preference. For example, the ratio of the volume of the humectant 261 to the tobacco medium 260 may be in the range of 1.1 to 2 times, preferably in the range of 1.2 to 1.5 times.

For example, the moisturizer 361 may be in the form of a wax and may be distinguished from each other. Each of the tobacco medium 360 and the nicotine powder 362 is contained in a moisturizing agent 361 separated from each other, and each of the moisturizing agents 361 may be combined with each other. In the embodiment shown in FIG. 3 , the moisturizing agent 361 containing the tobacco medium 360 and the moisturizing agent 361 containing the nicotine powder 362 are simply stacked, but are not limited thereto. For example, the humectant 361 containing the nicotine powder 362 may be laminated to wrap the outside of the moisturizer 361 containing the tobacco medium 360 .

As described below, after the cartridge 300 is inserted into the aerosol generating device 1000, when the chamber 311 of the cartridge 300 is heated by the heater 130, the moisturizing agent 361 in the form of wax is primarily liquefied. . Thereafter, an aerosol is generated from the moisturizing agent 361 as heating continues. In addition, nicotine is first expressed and transported from the nicotine powder 362 among the solid tobacco medium 360 and nicotine powder 362 , and then nicotine is expressed and transported from the tobacco medium 360 .

4 is a view showing another example of the cartridge shown in FIG.

Referring to FIG. 4 , the tobacco medium 460 may be stored in the chamber 411 in a state immersed in the moisturizing agent 461 . When the humectant 461 is in a liquid state, the humectant 461 may be surrounded by an outer wall 462 formed of a temperature-sensitive polymer that is removed when heated to maintain the humectant 461 . Accordingly, when the aerosol generating device 1000 is used, the temperature-sensitive outer wall 462 may be removed by heat transferred from the heater 130 .

When the chamber 411 of the cartridge 400 is heated by the heater 130 after the cartridge 400 is inserted into the aerosol generating device 1000 as described below, the temperature-sensitive outer wall 462 is primarily removed while the liquid phase of the moisturizing agent 461 flows into the chamber 411 of the cartridge 400 . Thereafter, as heating continues, an aerosol is generated from the moisturizing agent 461 while nicotine is expressed in the solid tobacco medium 460 and transported together with the aerosol.
