  8. The aforementioned second cartridge is The aerosol generator according to claim 1, comprising 0.1 to 5% by weight of liquid nicotine and 95 to 99.9% by weight of a second aerosol-forming agent.
  9. The control unit, In response to the determination that the set mode is the smokeless mode, The aerosol generating apparatus according to claim 1, wherein only the heater section is operated.
  10. The aforementioned heater section is The aerosol generator according to claim 1, wherein the device is arranged to heat only the cavity segment.
  11. The heater section, the first cartridge heater section, and the second cartridge heater section are: The aerosol generator according to claim 1, which is driven in such a manner that it is initially preheated and then reheated when it leaves a set range.
  12. The aerosol generator further includes a switch located on the outer wall surface of the housing, The aerosol generator according to claim 3 , wherein the switch is a means for setting a smoke mode or a smokeless mode, and when smoke mode is selected, setting it to one of the following modes: general mode, boosting mode, and combined boosting mode.
  13. The aerosol generating device is The aerosol generating apparatus according to claim 1, further comprising a channel for directly moving the aerosol generated from the second cartridge to the first filter segment when the aerosol generating article is contained within it.

Description

This invention relates to an aerosol generating device equipped with multiple cartridges. Specifically, it relates to an aerosol generating device that separately includes a cartridge containing an aerosol-forming substrate and a cartridge containing nicotine. This application claims priority based on Korean Patent Application No. 10-2021-0145593 dated October 28, 2021, and incorporates all the contents disclosed in the relevant Korean Patent Application as part of this Specification. Recently, there has been increasing demand for alternatives that overcome the shortcomings of traditional cigarettes. For example, there is growing demand for devices that generate aerosols by electrically heating cigarette sticks (e.g., cigarette-type e-cigarettes). Consequently, research into electrically heated aerosol generators and the cigarette sticks (or aerosol-generating articles) used with them is actively progressing. On the other hand, if no visible smoke is produced during smoking, it has the advantage of allowing users to enjoy smoking without restrictions on location or environment. Furthermore, this advantage has led to the development of smokeless tobacco products such as snuff, snus, and chewing tobacco. However, these smokeless tobacco products have the disadvantage of not providing the same smoking sensation as conventional cigarettes or heated tobacco sticks. Conversely, some smokers prefer to inhale while producing visible smoke, depending on their preference. Beyond the differences in preference based on the presence or absence of visible smoke, even among those who prefer visible smoke, there are differences in preference regarding the amount of atomization, and individual preferences regarding the amount of nicotine transferred also vary depending on the smoker's taste preferences for tobacco. Therefore, there is a need for research and development into aerosol generators that allow smokers to directly adjust the presence or absence of visible smoke during smoking, the amount of vaporization, and the amount of nicotine transferred, thereby providing a vaporization amount and taste that suits each individual's preferences and satisfying smokers. Japanese Patent Publication No. 2021-045149 This figure shows a schematic example of an aerosol generator operating in smokeless mode in one embodiment of the present invention.This figure shows a schematic example of an aerosol generator operating in smoke mode in one embodiment of the present invention.This figure shows a schematic example of an aerosol-generating article in one embodiment of the present invention.This figure shows the amount of nicotine transferred to an aerosol-generating article in one embodiment of the present invention, specifically in either Example 1 (general mode) or Example 2 (composite booster mode) of the smoke-generating mode. The present invention will be described in more detail below. The terms and words used in this specification and the claims shall not be interpreted in a manner limited to their ordinary or dictionary meanings, but rather in a manner and concept appropriate to the technical idea of the present invention, in accordance with the principle that inventors may appropriately define the concepts of terms in order to best describe their invention. The terms used in this invention are used solely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly intends otherwise. In this invention, terms such as "includes" or "has" are intended to specify the existence of features, figures, stages, operations, components, parts, or combinations thereof described in the specification, and should not be understood to preemptively exclude the possibility of the existence or addition of one or more other features, figures, stages, operations, components, parts, or combinations thereof. The terms "front side" and "rear side" used in this invention are defined based on the aerosol flow. The term "aerosol-forming agent" as used in this invention may refer to a substance that facilitates the formation of visible smoke and/or aerosols. In the art, "aerosol-forming agent" may be used interchangeably with terms such as humectant, wetting agent, etc. As used in this invention, the term "aerosol-forming substrate" may mean a substance capable of forming an aerosol. Aerosols may include volatile compounds. Aerosol-forming substrates may be solid or liquid. For example, a solid aerosol-forming substrate may include solid substances derived from tobacco raw materials such as flat tobacco leaves, shredded tobacco, or reconstituted tobacco, while a liquid aerosol-forming substrate may include liquid compositions derived from nicotine, tobacco extracts, and/or various flavoring agents. However, the scope of this disclosure is not limited to such examples. Aerosol-forming substrates may further include aerosol-forming agents to stably form visible smok
