Although the aerosol generating device 10000 shown in FIGS. 1 and 2 includes a vaporizer, embodiments are not limited by the implementation method of such aerosol generating device, and the vaporizer may be omitted from the aerosol generating device 10000. there is. If the vaporizer is omitted in the aerosol generating device 10000, the cigarette 20000 may contain an aerosol generating material and thus generate an aerosol when the cigarette 20000 is heated by the heater 13000.

Components related to this embodiment are shown in the aerosol generating device 10000 shown in FIGS. 1 and 2. Accordingly, those skilled in the art can understand that in addition to the components shown in FIGS. 1 and 2, other general-purpose components may be further included in the aerosol generating device 10000. .

1 and 2 show that the aerosol generating device 10000 includes a heater 13000, but if necessary, the heater 13000 may be omitted.

In Figure 1, a battery 11000, a control unit 12000, a vaporizer 14000, and a heater 13000 are shown arranged in a row. Additionally, Figure 2 shows a vaporizer 14000 and a heater 13000 arranged in parallel. However, the internal structure of the aerosol generating device 10000 is not limited to that shown in FIG. 1 or FIG. 2. In other words, depending on the design of the aerosol generating device 10000, the arrangement of the battery 11000, control unit 12000, vaporizer 14000, and heater 13000 may be changed.

When the cigarette 20000 is inserted into the aerosol generating device 10000, the aerosol generating device 10000 operates the vaporizer 14000 to generate an aerosol from the vaporizer 14000. The aerosol generated by the vaporizer (14000) passes through the cigarette (20000) and is delivered to the user. The vaporizer 14000 will be described in more detail below.

The battery 11000 supplies power used to operate the aerosol generating device 10000. For example, the battery 11000 can supply power so that the heater 13000 or the vaporizer 14000 can be heated, and can supply power necessary for the control unit 12000 to operate. Additionally, the battery 11000 can supply power necessary for the display, sensor, motor, etc. installed in the aerosol generating device 10000 to operate.

The control unit 12000 generally controls the operation of the aerosol generating device 10000. Specifically, the control unit 12000 controls the operation of the battery 11000, heater 13000, and vaporizer 14000, as well as other components included in the aerosol generating device 10000. Additionally, the control unit 12000 may check the status of each component of the aerosol generating device 10000 and determine whether the aerosol generating device 10000 is in an operable state.

The control unit 12000 includes at least one processor. The processor may be implemented as an array of multiple logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program that can be executed on the microprocessor. Additionally, those skilled in the art can understand that the present embodiment may be implemented with other types of hardware.

The heater 13000 may be heated by power supplied from the battery 11000. For example, when a cigarette is inserted into the aerosol generating device 10000, the heater 13000 may be located outside the cigarette. Accordingly, the heated heater 13000 can increase the temperature of the aerosol-generating material in the cigarette.

Heater 13000 may be an electrical resistance heater. For example, the heater 13000 includes an electrically conductive track, and the heater 13000 may be heated as a current flows through the electrically conductive track. However, the heater 13000 is not limited to the above-described example, and may be any heater that can be heated to a desired temperature without limitation. Here, the desired temperature may be preset in the aerosol generating device 10000, or may be set to a desired temperature by the user.

Meanwhile, as another example, the heater 13000 may be an induction heating type heater. Specifically, the heater 13000 may include an electrically conductive coil for heating a cigarette by an induction heating method, and the cigarette may include a susceptor that can be heated by an induction heating type heater.

1 and 2 show that the heater 13000 is disposed outside the cigarette 20000, but the present invention is not limited thereto. For example, the heater 13000 may include a tubular heating element, a plate-shaped heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the inside or outside of the cigarette 20000 depending on the shape of the heating element.

Additionally, some of the plurality of heaters 13000 may be arranged to be inserted into the inside of the cigarette 20000, and others may be placed outside the cigarette 20000. Additionally, the shape of the heater 13000 is not limited to the shape shown in FIGS. 1 and 2 and can be manufactured in various shapes.

The vaporizer 14000 can generate an aerosol by heating the liquid composition, and the generated aerosol can pass through the cigarette 20000 and be delivered to the user. In other words, the aerosol generated by the vaporizer 14000 can move along the airflow passage of the aerosol generating device 10000, and the airflow passage allows the aerosol generated by the vaporizer 14000 to pass through the cigarette and be delivered to the user. It can be configured to be possible.

For example, vaporizer 14000 may include, but is not limited to, a liquid reservoir, a liquid delivery means, and a heating element. For example, the liquid reservoir, liquid delivery means, and heating element may be included in the aerosol generating device 10000 as independent modules.

The liquid storage unit may store a liquid composition. For example, the liquid composition may be a liquid containing tobacco-containing substances, including volatile tobacco flavor components, or may be a liquid containing non-tobacco substances. The liquid storage unit may be manufactured to be detachable from/attached to the vaporizer 14000, or may be manufactured as an integral piece with the vaporizer 14000.

For example, liquid compositions may include water, solvents, ethanol, plant extracts, fragrances, flavors, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint, spearmint oil, and various fruit flavor ingredients. Flavoring agents may include ingredients that can provide various flavors or flavors to the user. The vitamin mixture may be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. Additionally, the liquid composition may contain aerosol formers such as glycerin and propylene glycol.

The liquid delivery means may deliver the liquid composition of the liquid reservoir to the heating element. For example, the liquid delivery means may be, but is not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

The heating element is an element for heating the liquid composition delivered by the liquid delivery means. For example, the heating element may be a metal heating wire, a metal heating plate, a ceramic heater, etc., but is not limited thereto. Additionally, the heating element may be composed of a conductive filament, such as a nichrome wire, and may be arranged in a structure wound around the liquid delivery means. The heating element may be heated by supplying an electric current and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, aerosols may be generated.

For example, the vaporizer 14000 may be referred to as a cartomizer or an atomizer, but is not limited thereto.

Meanwhile, the aerosol generating device 10000 may further include general-purpose components in addition to the battery 11000, the control unit 12000, and the heater 13000. For example, the aerosol generating device 10000 may include a display capable of outputting visual information and/or a motor for outputting tactile information. Additionally, the aerosol generating device 10000 may include at least one sensor (puff detection sensor, temperature detection sensor, cigarette insertion detection sensor, etc.). Additionally, the aerosol generating device 10000 may be manufactured in a structure that allows external air to flow in or internal gas to flow out even when the cigarette 20000 is inserted.

Although not shown in FIGS. 1 and 2, the aerosol generating device 10000 may form a system with a separate cradle. For example, the cradle can be used to charge the battery 11000 of the aerosol generating device 10000. Alternatively, the heater 13000 may be heated while the cradle and the aerosol generating device 10000 are combined.

The cigarette (20000) may be similar to a regular combustion-type cigarette. For example, the cigarette 20000 may be divided into a first part containing an aerosol-generating material and a second part containing a filter, etc. Alternatively, the second portion of the cigarette 20000 may also contain an aerosol-generating material. An aerosol-generating material, for example in the form of granules or capsules, may be inserted into the second part.

The entire first part may be inserted into the aerosol generating device 10000, and the second part may be exposed to the outside. Alternatively, only part of the first part may be inserted into the aerosol generating device 10000, or parts of the first part and the second part may be inserted. The user may inhale the aerosol while holding the second portion with his or her mouth. At this time, the aerosol is generated by external air passing through the first part, and the generated aerosol is delivered to the user's mouth by passing through the second part.

As an example, external air may be introduced through at least one air passage formed in the aerosol generating device 10000. For example, the opening and closing of the air passage formed in the aerosol generating device 10000 and/or the size of the air passage may be adjusted by the user. Accordingly, the amount of atomization, smoking sensation, etc. can be adjusted by the user. As another example, external air may be introduced into the cigarette 20000 through at least one hole formed on the surface of the cigarette 20000.

Hereinafter, with reference to FIG. 3, an example of cigarette 20000 will be described.

In FIG. 3, the filter rod 22000 is shown as a single segment, but the present invention is not limited thereto. In other words, the filter rod 22000 may be composed of a plurality of segments. For example, the filter rod 22000 may include a first segment that cools the aerosol and a second segment that filters certain components contained in the aerosol. Additionally, if necessary, the filter rod 22000 may further include at least one segment that performs another function.

A cigarette (20000) may be packaged by at least one wrapper (24000). At least one hole may be formed in the wrapper 24000 through which external air flows in or internal gas flows out. As an example, cigarettes 20000 may be packaged by one wrapper 24000. As another example, the cigarette 20000 may be overlappingly packaged by two or more wrappers 24000. For example, the cigarette rod 21000 may be packaged by a first wrapper, and the filter rod 22000 may be packaged by a second wrapper. In addition, the cigarette rod 21000 and the filter rod 22000 packaged by individual wrappers can be combined, and the entire cigarette 20000 can be repackaged by the third wrapper. If each of the tobacco rods 21000 or filter rods 22000 consists of a plurality of segments, each segment may be wrapped with an individual wrapper. And, the entire cigarette (20000) in which the segments packaged by individual wrappers are combined can be repackaged by another wrapper.

Additionally, the tobacco rod 21000 may be manufactured from a cut tobacco sheet in which the tobacco sheet is cut into small pieces. Additionally, the tobacco rod 21000 may be surrounded by a heat-conducting material. For example, the heat-conducting material may be, but is not limited to, a metal foil such as aluminum foil. As an example, the heat-conducting material surrounding the tobacco rod 21000 can improve the heat conductivity applied to the tobacco rod by evenly dispersing the heat transferred to the tobacco rod 21000, thereby improving the taste of the tobacco. . Additionally, the heat-conducting material surrounding the tobacco rod 21000 may function as a susceptor that is heated by an induction heater. At this time, although not shown in the drawing, the tobacco rod 21000 may further include an additional susceptor in addition to the heat-conducting material surrounding the outside.

Filter rod 22000 may be a cellulose acetate filter. Meanwhile, the shape of the filter rod 22000 is not limited.

Additionally, the filter rod 22000 may include at least one capsule 23000. Here, the capsule 23000 may perform a flavor generating function or an aerosol generating function. For example, the capsule 23000 may have a structure in which a liquid containing fragrance is wrapped with a film. The capsule 23000 may have a spherical or cylindrical shape, but is not limited thereto.

If the filter rod 22000 includes a segment that cools the aerosol, the cooling segment may be made of a polymer material or a biodegradable polymer material. For example, but not limited to, the cooling segment may be made entirely from pure polylactic acid. Alternatively, the cooling segment can be made from a cellulose acetate filter with a plurality of holes drilled into it. However, the cooling segment is not limited to the above-described example, and may be applicable without limitation as long as the aerosol can perform the function of cooling.

Meanwhile, although not shown in FIG. 3, the cigarette 20000 according to one embodiment may further include a front end filter. The front end filter may be located on one side of the tobacco rod 21000 opposite to the filter rod 22000.
