Definitions
- the following embodiments relate to an aerosol generating article and an aerosol generating system.
- KR Patent Application Publication No. 10-2017-0132823 discloses a non-combustion-type flavor inhaler, a flavor inhalation component source unit, and an atomizing unit.
- An embodiment is to provide an aerosol generating article that may implement a desired amount of nicotine transfer through indirect heating despite a relatively low level of pH treatment and an aerosol generating system including the same.
- An embodiment is to provide an aerosol generating system that may generate an aerosol using an aerosol generating device not equipped with a separate vaporizer.
- An embodiment is to provide an aerosol generating article that may minimize instability caused by free nicotine according to pH adjustment and an aerosol generating system including the same.
- an aerosol generating article includes an atomization segment; and a medium segment configured to be pH-treated and disposed downstream of the atomization segment, wherein, when the atomization segment is heated, heat from the heated atomization segment may be transferred indirectly to the medium segment.
- the aerosol generating article may further include a filter segment disposed downstream of the medium segment, the filter segment with nicotine adsorbed.
- the nicotine adsorbed into the filter segment may be transferred from the medium segment.
- the medium segment may be pH-treated such that the pH thereof may be in the range of 7.0 to 9.5.
- the aerosol generating article may further include a thermally conductive wrapper configured to wrap the atomization segment, and the thermally conductive wrapper may further wrap the medium segment.
- a medium used to fill the medium segment may include at least one component of reconstituted tobacco sheets and tobacco granules.
- a moisturizing agent used to fill the atomization segment may include at least one component of glycerin and propylene glycol.
- an aerosol generating system includes an aerosol generating article including an atomization segment, a medium segment disposed downstream of the atomization segment, and a filter segment disposed downstream of the medium segment, and an aerosol generating device including a controller including at least one processor; a heater configured to heat the aerosol generating article; and an elongated cavity configured to receive the aerosol generating article, wherein nicotine may be adsorbed into the filter segment.
- the medium segment may be pH-treated, and the nicotine adsorbed into the filter segment may be transferred from the medium segment.
- the medium segment may be pH-treated, and when the heater heats the atomization segment, heat from the heated atomization segment may be transferred indirectly to the medium segment.
- the aerosol generating article may further include a thermally conductive wrapper configured to wrap at least one of the atomization segment and the medium segment, the thermally conductive wrapper including an aluminum component.
- An aerosol generating article and aerosol generating system may cause efficient and uniform nicotine transfer.
- An aerosol generating article and aerosol generating system may provide a uniform intensity of smoking taste.
- An aerosol generating article and aerosol generating system may reduce the appearance of off-flavors and off-odors.
- the "moisturizing agent” may refer to a substance capable of facilitating the formation of visible smoke and/or an aerosol.
- the moisturizing agent may include, for example, glycerin (GLY), propylene glycol (PG), ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto.
- GLY glycerin
- PG propylene glycol
- ethylene glycol dipropylene glycol
- diethylene glycol diethylene glycol
- triethylene glycol tetraethylene glycol
- oleyl alcohol oleyl alcohol
- an "aerosol forming material” may refer to a material that forms an aerosol.
- the aerosol may include a volatile compound.
- the aerosol forming material may be solid or liquid.
- a solid aerosol forming material may include solid materials based on tobacco raw materials such as reconstituted tobacco sheets, cut tobacco leaves, and reconstituted tobacco
- a liquid aerosol forming material may include a liquid composition based on nicotine, a tobacco extract, and/or various fragrances.
- the scope of the disclosure is not limited to these examples.
- the term "aerosol generating article” may refer to an article that accommodates a medium, in which an aerosol passes through the article and the medium is transferred.
- a representative example of the aerosol generating article may be a cigarette.
- the scope of the disclosure is not limited thereto.
- the term "aerosol generating device” may refer to a device that generates an aerosol using an aerosol forming material to generate an aerosol that may be inhaled through the mouth of a user directly to the lungs of the user.
- upstream or “upstream direction” may refer to a direction away from a mouth of a user (smoker), and the terms “downstream” or “downstream direction” may refer to a direction toward the mouth of the user.
- upstream and downstream may be used to describe relative positions of components of the aerosol generating article.
- the term "puff” refers to inhalation by a user, and inhalation refers to a situation in which a user draws in an aerosol into his or her oral cavity, nasal cavity, or lungs through the mouth or nose.
- FIG. 1 is a block diagram of an aerosol generating article according to an embodiment
- FIG. 2 is a diagram schematically illustrating the structure of an aerosol generating device
- FIG. 3 is a view schematically illustrating the structure of the aerosol generating article according to an embodiment
- FIG. 4 is a view schematically illustrating an aerosol generating system in which the aerosol generating article is coupled to the aerosol generating device according to an embodiment.
- an aerosol generating device 11 includes a battery 111, a controller 112, a heater 113, and an elongated cavity 114.
- the aerosol generating device 11 shown in FIGS. 1 and 2 . Therefore, it is to be understood by those having ordinary skill in the art to which the disclosure pertains that the aerosol generating device 11 may further include other general-purpose components in addition to the components shown in FIGS. 1 and 2 .
- FIG. 2 illustrates a linear alignment of the battery 111, the controller 112, and the heater 113.
- the internal structure of the aerosol generating device 11 is not limited to what is shown in FIG 2 . That is, the alignment of the battery 111, the controller 112, and the heater 113 may be changed depending on the design of the aerosol generating device 11.
- the aerosol generating device 11 may operate the heater 113 to generate an aerosol.
- the aerosol generated by the heater 113 may pass through the aerosol generating article 12 into a user.
- the aerosol generating device 11 may heat the heater 113, as needed.
- the battery 111 may supply power to be used to operate the aerosol generating device 11.
- the battery 111 may supply power to heat the heater 113, and may supply power required to operate the controller 112.
- the battery 111 may supply power required to operate a display, a sensor, a motor, or the like installed in the aerosol generating device 11.
- the controller 112 may control the overall operation of the aerosol generating device 11. Specifically, the controller 112 may control respective operations of other components included in the aerosol generating device 11, in addition to the battery 111 and the heater 113. In addition, the controller 112 may verify a state of each of the components of the aerosol generating device 11 to determine whether the aerosol generating device 11 is in an operable state.
- the controller 112 includes at least one processor.
- the processor may be implemented as an array of a plurality of logic gates, or may be implemented as a combination of a general-purpose microprocessor and a memory in which a program executable by the microprocessor is stored.
- the processor may be implemented in other types of hardware.
- the heater 113 may be heated by the power supplied by the battery 111.
- the heater 113 may be disposed outside the aerosol generating article 12. The heated heater 113 may thus raise the temperature of an aerosol generating material in the aerosol generating article 12.
