In addition, terms such as "… section" and "… module" described in the present specification mean a unit for processing at least one function or operation, and may be implemented in hardware, software, or a combination of hardware and software.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that those skilled in the art can easily implement the embodiments. The invention is not, however, limited to the embodiments described herein but may be embodied in various different forms.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, the aerosol-generating device 1000 includes a battery 1100, a control unit 1200, and a heater 1030. Additionally, a cigarette 2000 may be inserted into the interior space of the aerosol-generating device 1000.

The aerosol-generating device 1000 shown in fig. 1 shows only the components relevant to the present embodiment. Therefore, as long as a person having ordinary skill in the art related to the present embodiment can understand, the aerosol-generating device 1000 may further include other general components in addition to those shown in fig. 1.

Although fig. 1 illustrates a case where the battery 1100, the control portion 1200, and the heater 1030 are sequentially arranged, it is not limited thereto. In other words, the arrangement of the battery 1100, the controller 1200, and the heater 1030 may be changed according to the design of the aerosol-generating device 1000.

When the cigarette 2000 is inserted into the aerosol-generating device 1000, the aerosol-generating device 1000 heats the heater 1030. The temperature of the aerosol-generating substance in the cigarette 2000 is raised by the heated heater 1030, thereby enabling the aerosol to 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 device 1000, the aerosol-generating device 1000 may heat the heater 1030 even when the cigarette 2000 is not inserted into the aerosol-generating device 1000.

The battery 1100 supplies power for operating the aerosol-generating device 1000. For example, the battery 1100 may supply power to heat the heater 1030 and supply power necessary for operation to the control unit 1200. The battery 1100 can supply power necessary for operation to a display, a sensor, a motor, and the like provided in the aerosol-generating device 1000.

The control unit 1200 controls the operation of the aerosol-generating device 1000 as a whole. Specifically, the control unit 1200 controls the operations of other components included in the aerosol-generating device 1000 in addition to the battery 1100 and the heater 1030. The control unit 1200 may check the state of each component of the aerosol-generating device 1000 to determine whether the aerosol-generating device 1000 is operable.

The control section 1200 includes at least one processor. The processor may be constituted by a plurality of logic gate arrays, or may be constituted by a combination of a general-purpose microprocessor and a memory in which a program executable by the microprocessor is stored. It should be noted that the present invention may be implemented by other hardware as long as a person who is ordinary skilled in the art can understand the present invention.

The heater 1030 may be heated by power supplied from the battery 1100. For example, the heater 1030 may be located inside a cigarette when the cigarette is inserted into the aerosol-generating device 1000. Thus, the heated heater 1030 can raise the temperature of the aerosol generating substance within the cigarette.

Heater 1030 may be a resistive heater. For example, the heater 1030 includes a conductive track (track), and the heater 1030 is heated when current flows in the conductive track. However, the heater 1030 is not limited to the above example, and is not particularly limited as long as it can be heated to a desired temperature. The desired temperature may be set in advance in the aerosol-generating device 1000, or may be set to a desired temperature by the user.

In another example, the heater 1030 may be an induction heating heater. Specifically, the heater 1030 may comprise an electrically conductive coil for heating a cigarette by induction heating, and the cigarette may comprise a heat conductor (heater) capable of being heated by the induction heating heater.

Although fig. 1 shows a case where the heater 1030 is configured to be inserted into the interior of the cigarette 2000, it is not limited thereto. For example, the heater 1030 may include a tube-shaped heating member, a plate-shaped heating member, a needle-shaped heating member, or a rod-shaped heating member, and may heat the inside or outside of the cigarette 2000 according to the shape of the heating member.

Additionally, the aerosol-generating device 1000 may be configured with a plurality of heaters 1030. In this case, the plurality of heaters 1030 may be disposed to be inserted into the interior of the cigarette 2000, and may be disposed at the exterior of the cigarette 2000. Further, some of the plurality of heaters 1030 may be disposed so as to be inserted into the cigarette 2000, and the other heaters may be disposed outside the cigarette 2000. The shape of the heater 1030 is not limited to the shape shown in fig. 1, and various other shapes may be used.

In one aspect, the aerosol-generating device 1000 may also include other common components in addition to the battery 1100, the control 1200, and the heater 1030. For example, the aerosol-generating device 1000 may include a display for outputting visual information and/or a motor for outputting tactile information. Additionally, the aerosol-generating device 1000 may include at least one sensor (puff detection sensor, temperature detection sensor, cigarette insertion detection sensor, etc.).

The aerosol-generating device 1000 may have a structure that allows outside air to flow in or allows inside air to flow out even when the cigarette 2000 is inserted.

Although not shown in fig. 1, the aerosol-generating device 1000 may be configured as a system together with a separate cradle. For example, the cradle may be used to charge the battery 1100 of the aerosol-generating device 1000. Alternatively, the heater 1030 may be heated in a state where the carriage is coupled to the aerosol-generating apparatus 1000.

The cigarette 2000 may be a cigarette similar to a conventional combustion type cigarette. For example, the cigarette 2000 may be divided into a first portion 2100 comprising aerosol-generating substances and a second portion 2200 comprising filters or the like. Alternatively, the second portion 2200 of the cigarette 2000 may also comprise an aerosol generating substance. For example, an aerosol-generating substance made in the form of particles or capsules may also be inserted into the second portion 2200.

The interior of the aerosol-generating device 1000 may be inserted through the first portion 2100 and the second portion 2200 may be exposed to the exterior. Alternatively, the aerosol-generating device 1000 may be inserted into a part of the first portion 2100, or may be inserted into parts of the first portion 2100 and the second portion 2200. The user may inhale the aerosol while holding the second portion 2200 in the mouth. At this time, the aerosol is generated while the external air passes through the first portion 2100, and the generated aerosol is delivered to the mouth of the user through the second portion 2200.

As an example, the external air may flow in via at least one air channel formed in the aerosol-generating device 1000. For example, the opening and closing of the air passage formed in the aerosol-generating device 1000 and/or the size of the air passage may be adjusted by a user. Thus, the user can adjust the amount of atomization, the feeling of smoking, and the like. As another example, the external air may flow into the interior of the cigarette 2000 through at least one hole (hole) formed on the surface of the cigarette 2000.

Next, an example of the cigarette 2000 will be described with reference to fig. 2.

Fig. 2 is a diagram showing an example of a cigarette.

Referring to fig. 2, a cigarette 2000 includes a tobacco rod 2100 and a filter rod 2200. The first portion 2100 described with reference to figure 1 comprises a tobacco rod 2100 and the second portion 2200 comprises a filter rod 2200.

The filter rod 2200 shown in fig. 2 is a single segment structure, but is not limited thereto. In other words, the filter rod 2200 may be constructed from multiple segments. For example, the filter rod 2200 may include a first section for cooling the aerosol and a second section for filtering the specified components included in the aerosol. In addition, the filter rod 2200 may also include at least one section that performs other functions, as desired.

The cigarette 2000 is packaged with at least one wrapper 2400. The packing paper 2400 is formed with at least one hole (hole) for inflow of external air or outflow of internal gas. As an example, the cigarette 2000 may be packaged with a wrapper 2400. As another example, the cigarette 2000 may be stacked and packed with two or more packing sheets 2400. For example, the tobacco rod 2100 may be wrapped with a first wrapper and the filter rod 2200 may be wrapped with a second wrapper. Then, the tobacco rod 2100 and the filter rod 2200 each wrapped with a single wrapper are combined, and the whole cigarette 2000 is wrapped with a third wrapper. In the case where the tobacco rod 2100 or filter rod 2200 is comprised of a plurality of segments, respectively, each segment may be wrapped with a single wrapper. Further, the entire cigarette 2000 formed by combining the segments each wrapped with a single wrapping paper may be repackaged with another wrapping paper.

The tobacco rod 2100 may include an aerosol generating substance. For example, the aerosol-generating substance may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. In addition, tobacco rod 2100 may contain other added substances such as flavorants, humectants, and/or organic acids (organic acids). Further, a seasoning liquid such as menthol or a humectant may be added to the tobacco rod 2100 so as to be sprayed on the tobacco rod 2100.

The tobacco rod 2100 may be made in a variety of ways. For example, the tobacco rod 2100 may be made from sheet (sheet) material or may be made from strand (strand) material. In addition, the tobacco rod 2100 may be made of tobacco leaves obtained by cutting tobacco pieces into fine pieces. Additionally, the tobacco rod 2100 may be surrounded by a thermally conductive substance. For example, the heat conductive substance may be a metal foil such as an aluminum foil, but is not limited thereto. For example, the heat conductive substance surrounding the tobacco rod 2100 can uniformly disperse heat transferred to the tobacco rod 2100 to increase the heat conductivity applied to the tobacco rod, thereby improving the taste of tobacco. In addition, the heat conductive substance for surrounding the tobacco rod 2100 may function as a heat sensitive body that can be heated by the induction heating type heater. At this time, although not shown in the drawings, the tobacco rod 2100 may include other heat sensitive bodies in addition to the heat conductive substance for surrounding the outside.

The filter rod 2200 may be a cellulose acetate filter. In one aspect, there is no limitation on the shape of the filter rod 2200. For example, the filter rod 2200 may be a cylindrical (type) rod, and may be a tubular (type) rod having a hollow interior. In addition, the filter rod 2200 may be a semi-concealed type (receipt type) rod. If the filter rod 2200 is constructed from multiple segments, at least one of the multiple segments can be made in different shapes.

The filter rod 2200 can be configured to produce a flavor. For example, the filter rod 2200 may be sprayed with a flavored liquid, or another fiber coated with a flavored liquid may be inserted into the filter rod 2200.

Additionally, the filter rod 2200 can include at least one capsule 2300. Here, the capsule 2300 may function to generate flavor, or may function to generate aerosol. For example, the capsule 2300 may be configured such that a liquid containing a perfume is enclosed by 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 for cooling the aerosol, the cooling segment may be made of a polymeric or biodegradable polymeric material. For example, the cooling stage may be made of pure polylactic acid, but is not limited thereto. Alternatively, the cooling section may be made of a cellulose acetate filter perforated with a plurality of holes. However, the cooling segment is not limited to the above example, and is not particularly limited as long as it can function to cool the aerosol.

The aerosol-generating device 1000 of the embodiment shown in fig. 3 may comprise a housing 1001 and an outer shell 1002. The case 1002 is coupled to one end of the case 1001, and the case 1001 and the case 1002 together form the external appearance of the aerosol-generating device 1000.

The case 1001 forms a part of the external appearance of the aerosol-generating device 1000, and functions to protect various components housed therein.

The housing 1002 and the case 1001 may be made of a plastic material that does not easily transfer heat or a metal material whose surface is coated with a heat insulating substance. The housing 1002 and the case 1001 may be manufactured by, for example, an injection molding method, a 3D printing method, or a method of assembling small parts manufactured by injection molding.

A maintaining means (not shown) for maintaining the coupled state between the housing 1002 and the case 1001 may be provided between the housing 1002 and the case 1001. The retaining means may comprise, for example, a protrusion and a groove. The following structure may be adopted: the coupled state of the housing 1002 and the case 1001 is maintained by maintaining the state of inserting the protrusion into the groove, and the protrusion is moved by the operation button of the pressure applied by the user so that the protrusion is separated from the groove.

The holding means may include, for example, a magnet and a metal member attached to the magnet. In the case where the magnet is used as the holding means, the magnet may be provided on one of the housing 100 and the case 1002, and a metal member to be bonded to the magnet may be provided on the other, or the magnet may be provided on both the housing 1001 and the case 1002.

The housing 1002 is not an indispensable structure in the aerosol-generating device 1000 of the embodiment shown in fig. 3, so the housing 1002 may not be provided as necessary.

An outer hole 1002p into which the cigarette 2000 can be inserted is formed in the upper surface of the case 1002 coupled to the housing 1001. In addition, a track 1003r is formed on the upper surface of the housing 1002 at a position adjacent to the external hole 1002 p. A door 1003 slidably movable along the upper surface of the housing 1002 is provided on the rail 1003 r. The door 1003 can slide linearly along the rail 1003 r.

The door 1003 moves in the direction of the arrow in fig. 3 along the rail 1003r, thereby functioning to expose the external hole 1002p and the insertion hole 1004p for inserting the cigarette 2000 into the housing 1001 through the housing 1002 to the outside. The external hole 1002p of the housing 1002 functions to expose the insertion hole 1004p of the receiving channel 1004h for receiving the cigarette 2000 to the outside.

When the door 1003 exposes the external hole 1002p to the outside, the user inserts the end 2000b of the cigarette 2000 into the external hole 1002p and the insertion hole 1004p, thereby being able to mount the cigarette 2000 in the receiving passage 1004h formed inside the housing 1002.

In the embodiment shown in fig. 3, the door 1003 may be configured to move linearly with respect to the housing 1002. However, the embodiment is not limited to the structure in which the door 1003 is combined with the housing 1002. For example, the door 1003 may be assembled by a hinge to be rotatably provided at the housing 1002. In the case of the hinge assembly, the door 1003 may be rotated toward the side of the outer hole 1002p in the extending direction of the upper surface of the housing 1002, or the door 1003 may be rotated away from the upper surface of the housing 1002.

The rail 1003r has a shape of a concave groove, but the embodiment is not limited to the shape of the rail 1003 r. For example, the track 1003r may have a convex shape, or may extend in a curved line instead of a straight line.

A button 1009 is provided in the housing 1001. By operating the button 1009, the operation of the aerosol-generating apparatus 1000 can be controlled.

In a state where case 1002 is coupled to case 1001, an external air inflow gap 1002g through which air can flow into case 1002 is formed at a coupling portion between case 1002 and case 1001.

Figure 4 is a perspective view illustrating an operating state in which a part of components are separated from the aerosol-generating device of the embodiment illustrated in figure 3. Figure 5 is a perspective view illustrating an operating state in which a part of components are separated from the aerosol-generating device of the embodiment illustrated in figure 3. Figure 6 is a side cross-sectional view showing a portion of the components of the aerosol-generating device of the embodiment shown in figure 3.

As shown in fig. 4, in a state where the cigarette 2000 is inserted into the aerosol-generating device 1000, the user can inhale the aerosol from the mouth of the cigarette 2000.

When the use of the cigarette 2000 is finished, the user may perform a cleaning operation of removing the cigarette residue remaining inside the aerosol-generating device 1000 after separating the cigarette 2000 from the aerosol-generating device 1000.

The cleaning of the aerosol-generating device 1000 may be performed as follows: after the user separates the case 1002 from the case 1001 of the aerosol-generating device 1000, the cigarette support portion 4 is separated from the case 1001 so as to expose the internal space of the aerosol-generating device 1000, the heater 103, and the like to the outside, and remove the cigarette residue.

Referring to fig. 4, the housing 1002 may be coupled to one side end 1001a of the case 1001 so as to cover the cigarette supporting part 4 coupled to the one side end 1001a of the case 1001. In addition, the housing 1002 may be separated from the case 1001 as needed.

When the cigarette 2000 is removed from the aerosol-generating device 1000 after use of the cigarette 2000 is completed, the user can take out the cigarette 2000 from the housing 1001 while rotating the cigarette 2000 with the hand.

Alternatively, when the cigarette 2000 is removed from the aerosol-generating device 1000, as shown in fig. 4, the user rotates the cigarette 2000 and then pulls the housing 1002, thereby separating the housing 1002 together with the cigarette 2000 from the housing 1001.

When the cigarette 2000 is separated from the housing 1001 while being rotated, the adhesion state between the cigarette 2000 and the heater can be released, and the cigarette residue adhering to the cigarette 2000 can be discharged to the outside of the housing 1001 together with the cigarette 2000.

When the housing 1002 is pulled without rotating the cigarette 2000, the cigarette 2000 can be separated from the housing 1001, but a part of the cigarette 2000, for example, a tobacco part may remain on the heater 1030 side without being discharged from the housing 1001. In such a case, after the user separates the housing 1002 from the case 1001, the cigarette support portion 4 can be separated from the case 1001 as shown in fig. 5. At this time, the cigarette remaining portion remaining on the heater 1030 side is separated from the housing 1001 together with the cigarette support portion 4. Thereafter, the user can remove the remaining cigarette residue remaining in the separated cigarette support portion 4.

Referring to fig. 5 and 6, the aerosol-generating device 1000 includes: a housing 1001 into which a cigarette 2000 can be inserted; a hollow projecting tube 1020 projecting from one end 1001a of the housing 1001 and having an opening to the outside; a heater 1030 provided in the housing 1001 with an end 1031 inside the protruding tube 1020, and generating heat when an electric signal is applied; a heater fixing portion 1040 provided inside the protrusion pipe 1020 to support the heater 1030, and having an arc surface 1040r extending from an inner side surface of the protrusion pipe 1020. The aerosol-generating device 1000 further includes a cigarette support portion 4, and the cigarette support portion 4 may be coupled to the protruding tube 1020 or may be separated from the protruding tube 1020.

As shown in fig. 5, in a state where the cigarette holder 4 is coupled to the housing 1001, the user can separate the cigarette holder 4 from the housing 1001 by gripping the cigarette holder 4 with a hand and pulling it upward.

Referring to fig. 6, the protruding tube 1020 surrounds the heater 1030 to protect the heater 1030, and when the cigarette support part 4 is coupled to the protruding tube 1020, the protruding tube 1020 functions to support the cigarette support part 4.

Since the protruding tube 1020 has a hollow shape with an empty interior, the protruding tube 1020 has a coupling passage 1020h into which at least a part of the cigarette support portion 4 can be inserted. The upper end of the coupling channel 1020h is open to the outside in the upper direction of the aerosol-generating device 1000.

A heater 1030 is provided in the housing 1001, and the heater 1030 performs a function of heating the cigarette 2000. The heater 1030 is disposed in the housing 1001, and an upper end 1031 of the heater 1030 is located inside the protruding pipe 1020. If the cigarette 2000 is accommodated in the cigarette supporting part 4 in a state where the cigarette supporting part 4 is coupled to the protruded pipe 1020, the upper end 1031 of the heater 1030 is inserted into the bottom surface of the end 2000b of the cigarette 2000.

The heater 1030 is electrically connected to a battery (1100 in fig. 1) and a control unit (1200 in fig. 1) provided inside the housing 1001. In a state where end 1031 of heater 1030 is inserted into cigarette 2000, when power is supplied to heater 1030, heater 1030 is heated to heat cigarette 2000.

Referring to fig. 5, the cigarette support portion 4 may be inserted into the coupling passage 1020h inside the protruding tube 1020 through an opening of the protruding tube 1020. The cigarette support part 4 has an inner tub 10 for being inserted into the protruding tube 1020 and an outer tub 20 for supporting the inner tub 10.

Referring to fig. 6, the outer barrel 20 of the cigarette support portion 4 has an extended support surface 26, the extended support surface 26 projecting inwardly from the generally semi-cylindrical outer wall 20t and being spaced from the outer wall 20 t. When the cigarette support 4 is coupled to the protruding tube 1020, the protruding tube 1020 is inserted between the outer wall 20t and the extended support surface 26, so that the coupled state between the cigarette support 4 and the protruding tube 1020 can be stably maintained.

According to the stable coupling structure between the cigarette support portion 4 and the protruding tube 1020, even if external shock is applied to the aerosol-generating device 1000 by impact, the components of the aerosol-generating device 1000 can be prevented from being separated or damaged. Therefore, even if the aerosol-generating device 1000 is used for a long period of time, good durability and stability can be ensured.

In addition, when the cleaning work is performed, the cigarette supporting part 4 can be easily separated from the housing 1001, so that the cleaning work can be performed reliably and conveniently.

In addition, the protruding tube 1020 may function to directly supply external air to the end of the cigarette 2000. Referring to fig. 5, the protruding tube 1020 has an air hole 1020g for connecting the inside and the outside of the protruding tube 1020 and an air flow path 1020n extending along the surface of the protruding tube 1020 for guiding the air flow to the air hole 1020 g.

The air holes 1020g may be provided in plurality at intervals in the circumferential direction with respect to the center of the protruding pipe 1020 in the longitudinal direction. The air holes 1020g and the air flow paths 1020n form an air flow passage for allowing air outside the protruding tube 1020 to flow into the inside of the protruding tube 1020.

Referring to fig. 6, when the cigarette support part 4 is coupled to the protruding tube 1020, the extended support surface 26 of the cigarette support part 4 is inserted into the inside of the protruding tube 1020. While the extended support surface 26 of the cigarette support 4 moves downward along the protruding tube 1020, the heater 1030 located inside the protruding tube 1020 passes through the heater insertion port 10b of the cigarette support 4.

In a state where the cigarette holder 4 is coupled to the protruding pipe 1020, the end 1031 of the heater 1030 is positioned inside the cigarette holder 4 through the heater insertion port 10b of the cigarette holder 4. Accordingly, in a state where the cigarette support part 4 is coupled to the protruding pipe 1020, when the cigarette 2000 is accommodated in the cigarette support part 4, the end 1031 of the heater 1030 is inserted into the cigarette 2000.

When a user of the aerosol-generating device 1000 inserts the cigarette 2000 into the receiving channel 1004h, the cigarette 2000 moves along the cigarette support 4. When the end 2000b of the cigarette 2000 reaches the bottom surface of the cigarette support portion 4, a feeling that the bottom surface is in contact with the end 2000b of the cigarette 2000 is transmitted to the hand of the user holding the cigarette 2000. Therefore, the user can easily attach the cigarette 2000 to the aerosol-generating device 1000 by performing a simple operation of pushing the cigarette 2000 into the aerosol-generating device 1000 by holding the cigarette 2000 in his hand.

When the user separates the cigarette 2000 from the cigarette support portion 4, the user holds the cigarette 2000 with the hand and turns it, so that the cigarette 2000 can be taken out to the outside of the cigarette support portion 4. The cigarette 2000 and the heater 1030, which are adhered to each other by the cigarette residual substances, can be completely separated during the process in which the user holds and rotates the cigarette 2000 by hand.

After separating the cigarette 2000 from the cigarette support portion 4, the user can perform cleaning work on the inside of the cigarette support portion 4. When the user separates the cigarette holder 4 from the housing 1001 in order to perform the cleaning work, the user can take out the cigarette holder 4 to the outside of the housing 1001 by holding the cigarette holder 4 with the hand.

The heater fixing portion 1040 is provided inside the protruding tube 1020, and has a through hole 1040b through which the end 1031 of the heater 1030 can pass. The heater fixing portion 1040 may be disposed inside the case 1001 so as to be surrounded by the protruding tube 1020, and the protruding tube 1020 and the heater fixing portion 1040 may be configured to be separated from each other, so that a gap (gap) may be formed between the protruding tube 1020 and the heater fixing portion 1040 at a predetermined interval.

On the other hand, the upper end 1031 of the heater 1030 protrudes upward through the through hole 1040b of the heater fixing portion 1040, and is positioned inside the cigarette support portion 4 through the heater insertion port 10b of the protruding tube 1020.

The area of the heater insertion port 10b may be larger than the sectional area of the heater 1030 penetrating the heater insertion port 10 b. According to such a configuration, the outside air can flow out and in through the heater insertion port 10 b.

An inner space 50 is formed between the protruding tube 1020 and the cigarette support portion 4 and between the heater fixing portion 1040 and the cigarette support portion 4. In the case where the cigarette support part 4 is mounted to the protruding pipe 1020, one side of the internal space 50 communicates with the inflow channel 1004g for inflow of the outside air, and the other side of the internal space 50 communicates with the heater insertion port 10 b.

According to such a configuration, the outside air flowing into the inflow channel 1004g flows into the internal space 50 along the gap between the cigarette support portion 4 and the protruding portion 1020, passes through the heater insertion port 10b from the internal space 50 by the inhalation action of the user, passes through the cigarette 2000, and is inhaled by the user.

That is, the interior of the cigarette support portion 4 for inserting the cigarette 2000 and the internal space 50 can communicate with each other through a minute gap formed between the heater 1030 and the heater insertion port 10 b. At this time, the cigarette 2000 is heated to generate aerosol, but since liquefaction of aerosol also occurs at the same time, a liquid substance is generated at the end 2000b of the cigarette 2000 and leaks to the internal space 50 side through the gap formed between the heater 1030 and the heater insertion port 10 b. In addition, the aerosol remaining in the internal space 50 may be liquefied and condensed on the inner sidewall surface of the protruding pipe 1020, and flow downward along the inner sidewall surface of the protruding pipe 1020. Here, 'liquid substance' may mean moisture or aerosol substance contained in a tobacco sheet (tobacosheet) medium of the cigarette 2000.

If the liquid substance remaining in the internal space 50 flows into the gap (gap) formed between the protruding tube 1020 and the cigarette support portion 4, the liquid substance may penetrate into the aerosol-generating device 1000 along the inner side wall of the protruding tube 1020, and the battery 1100 or the control portion 120 may be damaged when the liquid substance penetrating into the inside wets the battery (1100 of fig. 1) or the control portion (1200 of fig. 1) for transmitting an electric signal to the heater 1030.

To solve such a problem, the arc-shaped surface 1040r of the heater fixing portion 1040 may function as a kind of a breakwater that collects the liquid substance flowing into the internal space 50 such that the liquid substance cannot permeate into the interior of the aerosol-generating device 1000 through a gap (gap) between the protruding tube 1020 and the heater fixing portion 1040.

In addition, the arcuate surface 1040r may perform the following assistance: the liquid substance generated in the internal space 50 can be transferred to the heater 1030 side without being solidified and attached to the corner of the internal space 50. For example, the liquid substance transferred to the heater 1030 side by the arc surface 1040r can be heated by the heater 1030 to become aerosol again.

In addition, the aerosol-generating device 1000 may further include a sealing member 1050, the sealing member 1050 being located between the protrusion tube 1020 and the heater fixing portion 1040 for sealing a gap between the protrusion tube 1020 and the heater fixing portion 1040.

The heater fixing portion 1040 may further have a sealing groove 1040h concavely formed from a surface abutting against the protrusion pipe 1020, and the sealing member 1050 may be disposed in the sealing groove 1040 h. However, the embodiment is not limited to this, and the seal member 1050 may be provided in a seal groove (not shown) formed on the side of the projecting pipe 1020.

The embodiment shown in the drawings describes a case where the sealing member 1050 is circular, but the embodiment is not limited thereto. The sealing member 1050 is made of an elastic (elastic) material, and is not limited to a specific shape as long as it can perform a sealing function of sealing a gap formed between the protruding tube 1020 and the heater fixing portion 1040 so that the liquid substance cannot permeate into the aerosol-generating device 1000 through the gap between the protruding tube 1020 and the heater fixing portion 1040.

Even in the case where the liquid substance accumulated in the internal space 50 overflows along the gap formed between the protrusion tube 1020 and the heater fixing portion 1040 by a height a of the arc-shaped surface 1040r of the heater fixing portion 1040, the sealing member 1050 can prevent the liquid substance from penetrating into the interior of the aerosol-generating device 1000, and thus can protect the battery 1100 and the control portion 1200 provided therein.

In another embodiment of the aerosol-generating device 1000 shown in fig. 7, the configuration of the heater fixing portion 2040, the installation positions of the sealing

members

2060 and 2070, and the coupling configuration of the base portion 2050, which will be described later, are the same as those described in fig. 6, and therefore, detailed description thereof will be omitted.

First, the heater fixing portion 2040 shown in fig. 7 will be explained. A heater fixing portion 2040 provided inside the projecting pipe 2020 and supporting the heater 2030, the heater fixing portion 2040 having a shield (bank) member 2040p projecting upward from the side in contact with the projecting pipe 2020; receiving grooves 2040ha, 2040hb, which are formed recessed from the surface contacting the protruding pipe 2020, receive a part of the protruding pipe 2020.

The "upper side" referred to herein means not only a vertical direction in which the shield member 2040p shown in the drawings protrudes, but also a direction intersecting with the horizontal direction. That is, the guard member 2040p may protrude in the vertical direction as shown in the drawing, but is not limited thereto. For example, the shielding member 2040p may protrude in the upward and lateral oblique line (slant) direction.

According to such a configuration, even when the liquid substance accumulated in the internal space 50 flows into the gap between the projection pipe 2020 and the heater fixing portion 2040, the liquid substance can be prevented from penetrating into the aerosol-generating device 1000 for the first time by the shield member 2040 p. Further, by providing the sealing member 2060 in the housing groove 2040hb to seal the gap between the projecting tube 2020 and the heater fixing portion 2040, the liquid substance can be prevented from penetrating into the inside again by the sealing member 2060.

Referring to fig. 7, the heater fixing portion 2040 of another embodiment is described as including two receiving grooves 2040ha, 2040hb, but the embodiment is not limited thereto, and the heater fixing portion 2040 may include more than one receiving groove.

For example, referring to fig. 7, the housing groove 2040ha adjacent to the heater 2030 accommodates a part of the projecting pipe 2020, and the sealing member 2060 may be provided in the housing groove 2040hb distant from the heater 2030, but not only a configuration opposite to this may be adopted, but also the sealing member 2060 may be provided in both the housing grooves 2040ha and 2040 hb.

In one aspect, the aerosol-generating device 1000 of the embodiment shown in fig. 7 may further comprise: a base portion 2050 provided inside the case 2001 and engaged with the protruding tube 2020 for surrounding and supporting a battery (1100 of fig. 1) and a control portion (1200 of fig. 2) which transmit an electric signal to the heater; and a sealing member 2070 located between the protruding tube 2020 and the base 2050 for sealing a gap between the protruding tube 2020 and the base 2050.

The sealing member 2070 may be provided in a sealing groove (not shown) formed in the protruding pipe 2020 or the base 2050 as in the sealing groove 1040h of the heater fixing portion 1040 shown in fig. 6, but the embodiment is not limited thereto. As another embodiment, no sealing groove is additionally formed on the protruding tube 2020 and the base 2050 shown in fig. 7, and a sealing member 2070 may be disposed between the protruding tube 2020 and the base 2050 in a compressed state.

That is, like the sealing member 1050 shown in fig. 6, the sealing

members

2060, 2070 shown in fig. 7 may also comprise an elastomeric material. That is, the sealing

members

2060 and 2070 can seal the gap between the projecting tube 2020 and the heater fixing portion 2040 and the gap between the projecting tube 2020 and the base portion 2050, and can prevent the liquid substance from penetrating into the aerosol-generating device 1000.

The description of the structure and effects of the embodiments is merely exemplary, and it should be understood by those skilled in the art that various modifications and equivalent other embodiments based on the embodiments may be implemented. Therefore, the true scope of the invention should be determined by the appended claims.
