Since the air flow path 212 serves to allow the compressed medium of the medium portion 211 to be smoothly transferred by aerosol, it is desirable that the medium sheet 213 wound around the side surface of the medium portion 211 be formed of a transparent material.
In an embodiment, when the medium portion 211 has a polygonal shape as shown in fig. 3c and is heated by the central heating type heater, the amount of insufficiently heated medium present near the edge of the medium portion to be discarded can be reduced.
Fig. 4a and 4b are diagrams schematically illustrating an aerosol-generating device 3 according to an embodiment.
Referring to fig. 4a and 4b, the aerosol-generating device 3 may comprise a housing 31, an elongated cavity 32, a heater 33, a battery 34, and a controller 35.
The housing 31 may be configured to house at least a portion of the aerosol-generating article 2 and house various electrical/mechanical components.
The elongated cavity 32 may house at least a portion of the aerosol-generating article 2. The aerosol-generating article 2 housed in the elongate cavity 32 may generate an aerosol when heated by the heater 33, and the generated aerosol may be inhaled through the mouth of a user.
The heater 33 may heat the aerosol-generating article 2 housed in the elongate cavity 32. In an embodiment, the heater 33 may include one or more heating elements (e.g., 331 and 332 of fig. 4 b). For example, when the aerosol-generating article 2 is housed in the elongate cavity 32, the heater 33 may comprise a first heating element 331 as an internal heating type heating element, the first heating element 331 heating the interior of the medium, i.e. the central portion of the medium, and the heater 33 may comprise a second heating element 332 as an external heating type heating element, the second heating element 332 heating the exterior of the medium, i.e. the peripheral portion of the medium. For example, the first heating element 331 and the second heating element 332 may be structures in a direct heating type, an induction heating type, or a hot air blowing heating type. Desirably, the first heating element 331 may be a blade type, a needle type, or a hot air blowing type (hot air blow type), and the second heating element 332 may be a contact (direct) heating type or an induction heating type. However, the embodiment is not limited thereto.
Referring to fig. 4b, the highest heating temperature of the first heating element 331 may be lower than the highest heating temperature of the second heating element 332. The first heating element 331 is an internal heating type heating element, and when the temperature of the first heating element 331 is too high, a user may taste a burnt smell because a medium in direct contact with the element is burnt. Accordingly, the medium in the aerosol-generating article 2 can be uniformly heated by setting the highest heating temperature of the second heating element 332, which is an external heating type heating element, to be lower than the highest heating temperature of the first heating element 331.
The battery 34 (e.g., the battery 140 of fig. 1) may provide electrical power for operating the aerosol-generating device 3. For example, the battery 34 may provide power to operate the heater 33 such that the medium portion 211 or aerosol-forming substrate in the aerosol-generating article 2 is heated, and may provide power to operate the controller 35 (e.g., the controller 110 of fig. 1). Further, the battery 34 may provide the power required to operate a display, a sensor, a motor, etc. installed in the aerosol-generating device 3.
The controller 35 (e.g., the controller 110 of fig. 1) controls the overall operation of the aerosol-generating device 3. For example, the controller 35 may control the power supplied from the battery 34 to the heater 33. In addition to the heater 33 and the battery 34, the controller 35 may also control the respective operations of other components included in the aerosol-generating device 3. Furthermore, the controller 35 may verify the status of each of the components of the aerosol-generating device 3 to determine whether the aerosol-generating device 3 is in an operational state.
The controller 35 may include at least one processor. The processor may be implemented as an array of a plurality of logic gates, or as a combination of a general purpose microprocessor and memory having stored therein a program executable by the microprocessor. Furthermore, those skilled in the art will appreciate that the processor may be implemented in other types of hardware.
Fig. 5 is a diagram schematically showing an aerosol-generating device 3 comprising a heater 33 according to another embodiment.
Referring to fig. 5, the heater 33 comprised in the aerosol-generating device 3 may protrude from one end of an elongated cavity (e.g. the elongated cavity 32 of fig. 4 a). The heater 33 may include a heating unit 33a generating heat substantially and a hot air blowing unit 33b discharging air heated by the heating unit 33a to the outside of the heater. With this configuration of the heater 33, the aerosol-generating article 3 may more effectively heat the medium and/or the aerosol-forming substrate when the aerosol-generating article 2 is housed in the elongate cavity 32 of the aerosol-generating device 3.
Fig. 6a and 6b are diagrams schematically illustrating an aerosol-generating system according to an embodiment.
Referring to fig. 6a and 6b, the aerosol-generating system may comprise an aerosol-generating article 2 and an aerosol-generating device 3, the aerosol-generating article 2 comprising a media rod 21 and a filter rod 22, wherein the media rod 21 comprises a media portion 211 housing a medium, a main airflow path 212a formed through a central portion of the media portion 211 in a longitudinal direction, and one or more sub-airflow paths 212b formed around the main airflow path 212a in parallel with the main airflow path 212, the aerosol-generating device 3 comprising: a housing (e.g. the housing 31 of fig. 4 a), an elongated cavity (e.g. the elongated cavity 32 of fig. 4 a), a heater 33 for heating the aerosol-generating article 2 housed in the elongated cavity.
Referring to fig. 6a, the medium contained in the medium portion 211 of the aerosol-generating article 2 may move towards the filter rod 22 when heated and atomized by the heater 33. At this time, the atomized medium may move to the downstream side along the main air flow path 212a and the sub air flow path 212b formed through the medium portion 211 in the longitudinal direction. The heater 33 is shown in fig. 6a as having a single unit. However, the embodiment is not limited thereto. For example, the heater 33 of the aerosol-generating device 3 may comprise one or more heating elements (e.g. 331, 332 of fig. 4 b), for example, the heater 33 may comprise a first heating element 331 and a second heating element 332, the first heating element 331 being an inner heating type heating element heating the interior (i.e. central portion) of the medium and the second heating element 332 being an outer heating type heating element heating the exterior (i.e. peripheral portion) of the medium when the aerosol-generating article 2 is housed in the elongate cavity 32. In an embodiment, the first heating element 331 and the second heating element 332 may be one of a direct heating type, an induction heating type, or a hot air blowing heating type.
The media bar 21 may further include a media sheet (e.g., media sheet 213 of fig. 3 c) wrapping the outer side surface of the media portion 211, a wrapper (e.g., wrapper 24 of fig. 3 c) wrapping the media sheet of the media bar 21, and a side air flow path 212c formed between the media sheet 213 and the wrapper 24 in the longitudinal direction. In addition to the main airflow path 212a and the sub airflow path 212b, the atomized medium may move to the downstream side along the side airflow path 212c.
Referring to fig. 6b, the aerosol-generating article 2 of the aerosol-generating system may further comprise an atomizing rod 23. The atomizing rod 23 may house an aerosol-forming substrate and may be disposed at an upstream end of the media rod 21. The heater 33 may heat the atomizing rod 23 and/or the heater 33 may heat the media rod 21 and the atomizing rod 23 when the aerosol-generating article 2 is received in the elongated cavity 32 of the aerosol-generating device 3. Thereby, a larger amount of aerosol can be generated and transferred into the mouth of the user.
