  3. The aforementioned heater section is The aerosol generating system according to claim 2, wherein the heating temperature of the aerosol generating article is varied in one of the following modes: strong mode, medium mode, and weak mode.
  4. The aforementioned heater section is In the aforementioned high-power mode, the device is heated to maintain a temperature of 200 to 260°C. In the aforementioned intermediate mode, the temperature is heated to be maintained at 160-200°C. The aerosol generating system according to claim 3, wherein the system is heated so as to maintain a temperature of 150 to 180°C in the weak mode.
  5. The control unit, The aerosol generating system according to claim 1, wherein, in response to the determination that the set mode is the smokeless mode, only the heater unit among the heater unit and the cartridge heater unit is operated.
  6. The aforementioned heater section is The aerosol generating system according to claim 5, which is heated to maintain a temperature of 200 to 260°C.
  7. The aforementioned heater section is The aerosol generating system according to claim 1, wherein the system is configured to heat only the cavity segment.
  8. The aforementioned heater section is The aerosol generating system according to claim 1, which is driven in such a way that it is initially preheated and then reheated when it leaves a set range.
  9. The aerosol generator further includes a switch located on the outer wall surface of the housing, The aerosol generating system 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 one of the modes: strong mode, medium mode, and weak mode.

Description

This invention relates to an aerosol generator equipped with a smokeless function. Specifically, it relates to an aerosol generator in which the user can select between a smoky or smokeless function, and in smoky mode, the user can easily select the heating temperature of the heater section. This application claims priority based on Korean Patent Application No. 10-2021-0145543 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 the experience of inhaling visible smoke. In addition to the differences in preference based on the presence or absence of visible smoke, there are also differences in tobacco flavor, which varies depending on the amount of nicotine transferred. Some smokers prefer a strong tobacco flavor, while others prefer a milder one. Therefore, there is a need for research and development into aerosol generators that can simultaneously satisfy the differing preferences of a large number of smokers regarding the presence or absence of visible smoke and the variety of tobacco flavors. 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. 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. Examples of aerosol-forming agents include, but are not limited to, glycerin (GLY), propylene glycol (PG), ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. In the art, aerosol-forming agents may be used interchangeably with terms such as humectants and wetting agents. 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 smoke and/or aerosols. The term "aerosol generator" as used in this invention may refer to a device that generates an aerosol using an aerosol-forming substrate in order to generate an aer
