Therefore, it will be understood by those skilled in the art that other general components other than the components shown in FIG. 1 may be further included in the aerosol generating apparatus 1000.

Although the battery 1100, the control unit 1200, and the heater 1030 are shown in FIG. 1 as being arranged in this order, the present invention is not limited thereto. In other words, according to the design of the aerosol generating apparatus 1000, the arrangement of the battery 1100, the control unit 1200, and the heater 1030 can be changed.

When the cigarette 2000 is inserted into the aerosol generating apparatus 1000, the aerosol generating apparatus 1000 heats the heater 1030. The aerosol product in the cigarette 2000 rises in temperature by the heated heater 1030, so that an aerosol can be generated. The generated aerosol is delivered to the user through the filter 22000 of the cigarette 2000.

For example, in order to clean the internal space of the aerosol generating apparatus 1000, even when the cigarette 2000 is not inserted into the aerosol generating apparatus 1000, the aerosol generating apparatus 1000 can heat the heater 1030 have.

The battery 1100 supplies power used to operate the aerosol generating apparatus 1000. For example, the battery 1100 can supply electric power so that the heater 1030 can be heated, and can supply the power required for the controller 1200 to operate. In addition, the battery 1100 can supply power required for the operation of a display, a sensor, a motor, and the like installed in the aerosol generating apparatus 1000.

The control unit 1200 controls the operation of the aerosol generating apparatus 1000 as a whole. Specifically, the control unit 1200 controls the operation of not only the battery 1100 and the heater 1030, but also other components included in the aerosol generating apparatus 1000. The control unit 1200 may also check the status of each of the configurations of the aerosol generation apparatus 1000 to determine whether the aerosol generation apparatus 1000 is in an operable state.

The control unit 1200 includes at least one processor. A 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 in the microprocessor is stored. It will be appreciated by those skilled in the art that the present invention may be implemented in other forms of hardware.

The heater 1030 is heated by electric power supplied from the battery 1100. For example, when the cigarette is inserted into the aerosol generating apparatus 1000, the heater 1030 may be located inside the cigarette. Thus, the heated heater 1030 can raise the temperature of the aerosol product in the cigarette.

The heater 1030 may be an electrically resistive heater. For example, the heater 1030 includes an electrically conductive track, and the heater 1030 can be heated as current flows through the electrically conductive track. However, the heater 1030 is not limited to the above-described example, and can be applied without limitation as long as it can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating apparatus 1000, or may be set to a desired temperature by the user.

On the other hand, as another example, the heater 1030 may be an induction heating type heater. Specifically, the heater 1030 may include an electrically conductive coil for heating the cigarette by an induction heating method, and the cigarette may include a susceptor that can be heated by an induction heating heater.

1, the heater 1030 is shown to be inserted into the cigarette 2000, but the present invention is not limited thereto. For example, the heater 1030 may include a tubular heating element, a plate-like heating element, a sinking heating element, or a bar-shaped heating element, and may be disposed inside or outside the cigarette 2000 It can be heated.

In addition, a plurality of heaters 1030 may be disposed in the aerosol generating apparatus 1000. At this time, the plurality of heaters 1030 may be disposed inside the cigarette 2000, or may be disposed outside the cigarette 2000. Also, some of the plurality of heaters 1030 may be arranged to be inserted into the cigarette 2000, and the rest may be disposed outside the cigarette 2000. Further, the shape of the heater 1030 is not limited to the shape shown in Fig. 1, but can be formed into various shapes.

Meanwhile, the aerosol generating apparatus 1000 may further include general configurations other than the battery 1100, the controller 1200, and the heater 1030.

Although not shown in FIG. 1, the aerosol generating apparatus 1000 may form a system together with a separate cradle. For example, the cradle may be used to charge the battery 1100 of the aerosol generating apparatus 1000. Alternatively, the heater 1030 may be heated while the cradle and the aerosol generating apparatus 1000 are coupled.

The cigarette 2000 may be similar to a typical soft cigarette. For example, the cigarette 2000 may be divided into a first portion 2100 comprising an aerosol product and a second portion 2200 including a filter or the like. Alternatively, the second portion 2200 of the cigarette 2000 may also include an aerosol generating material. For example, an aerosol product made in the form of granules or capsules may be inserted into the second portion 2200.

The entire first part 2100 may be inserted into the inside of the apparatus 1000 for generating aerosol and the second part 2200 may be exposed to the outside. Alternatively, only a part of the first part 2100 may be inserted into the aerosol generating apparatus 1000, and a part of the first part 2100 and the second part 2200 may be inserted. The user may inhale the aerosol from the second portion 2200 into the mouth. At this time, the aerosol is generated by passing outside air through the first portion 2100, and the generated aerosol passes through the second portion 2200 and is delivered to the user's mouth.

As an example, the outside air may be introduced through at least one air passage formed in the aerosol generating apparatus 1000. For example, the opening and closing of the air passage formed in the aerosol generating apparatus 1000 and / or the size of the air passage may be controlled by the user. Accordingly, the amount of smoke, the sense of smell, and the like can be controlled by the user. As another example, the outside air may be introduced into the interior of the cigarette 2000 through at least one hole formed in the surface of the cigarette 2000.

Hereinafter, an example of the cigarette 2000 will be described with reference to FIG.

For example, the thermally conductive material surrounding the tobacco rod 2100 can evenly disperse the heat transferred to the tobacco rod 2100 to improve the thermal conductivity applied to the tobacco rod, thereby improving the taste of the cigarette . In addition, the heat conducting material surrounding the tobacco rod 2100 can serve as a susceptor heated by the induction heating heater. At this time, although not shown in the drawing, the tobacco rod 2100 may further include an additional susceptor in addition to the heat conduction material surrounding the outside.

The filter rod 2200 may be a cellulose acetate filter. On the other hand, the shape of the filter rod 2200 is not limited. For example, the filter rod 2200 may be a cylindrical rod or a tubular rod including a hollow therein. Further, the filter rod 2200 may be a recessed type rod. If the filter rod 2200 is composed of a plurality of segments, at least one of the plurality of segments may be fabricated in a different shape.

The filter rod 2200 may be made to produce flavor. As an example, a return fluid may be injected into the filter rod 2200, and a separate fiber coated with the return fluid may be inserted into the interior of the filter rod 2200.

Also, the filter rod 2200 may include at least one capsule 2300. Here, the capsule 2300 may perform a function of generating flavor or may function to generate an aerosol. For example, the capsule 2300 may be a structure in which a content liquid containing a perfume is wrapped in a film. The capsule 2300 may have a spherical or cylindrical shape, but is not limited thereto.

If the filter rod 2200 includes a segment that cools the aerosol, the cooling segment may be made of a polymeric material or a biodegradable polymeric material. For example, the cooling segment may be made of pure polylactic acid alone, but is not limited thereto. Alternatively, the cooling segment may be made of a cellulose acetate filter having a plurality of holes. However, the cooling segment is not limited to the above-described example, and can be applied without restriction if it can perform the function of cooling the aerosol.

The heater fixing part 1040 may be installed inside the case 1001 so as to be surrounded by the protruding pipe 1020. Since the protruding pipe 1020 and the heater fixing part 1040 are separated from each other, A gap may be formed at a predetermined interval between the heater fixing portion 1040 and the heater fixing portion 1040.

The upper end portion 1031 of the heater 1030 protrudes upward through the through hole 1040b of the heater fixing portion 1040 and further passes through the heater insertion port 10b of the protruding tube 1020, (4).

The area of the heater inlet 10b may be larger than the cross-sectional area of the heater 1030 passing through the heater inlet 10b. According to this structure, outside air can flow in and out through the heater inlet 10b.

An internal space 50 is formed between the protruding tube 1020 and the cigarette supporting portion 4 and between the heater fixing portion 1040 and the cigarette supporting portion 4. [ One side of the inner space 50 communicates with the inflow passage 1004g through which the outside air flows when the cigarette support portion 4 is mounted on the protruding pipe 1020 and communicates with the heater inlet 10b on the other side.

According to this structure, the external air introduced into the inflow passage 1004g flows into the internal space 50 along the gap between the cigarette support portion 4 and the protruding portion 1020 and flows into the internal space 50 in accordance with the suction action of the user. The cigarette 2000 can be sucked into the user through the heater inlet 10b.

That is, the inside of the cigarette support portion 4 and the internal space 50 into which the cigarette 2000 is inserted can communicate with each other through a minute gap formed between the heater 1030 and the heater inlet 10b. At this time, the cigarette 2000 is heated to generate an aerosol, and at the same time, the aerosol is also liquefied, so that a liquid material is generated at the end 2000b of the cigarette 2000 and formed between the heater 1030 and the heater inlet 10b To the inner space (50) side through a gap formed between the inner space (50) and the inner space (50). The aerosol remaining in the inner space 50 may be liquefied and formed on the inner wall surface of the protruding pipe 1020 and may flow downward along the inner wall surface of the protruding pipe 1020. Here, the term 'liquid substance' may mean water or an aerosol substance contained in the medium of the plate of the cigarette 2000.
