Description

Aerosol generating device

The application is a divisional application of an invention patent application with application date of 2018, 6 and 15, application number of 201880050526.7(PCT/KR2018/006747) and invention name of 'aerosol generating device'.

Technical Field

Embodiments relate to an aerosol-generating device, and more particularly, to an aerosol-generating device in which a fastening structure is hidden from the outside.

Background

Recently, there is an increasing demand for alternative methods to overcome the disadvantages of ordinary cigarettes. For example, there is an increasing demand for methods which do not burn and generate an aerosol as the aerosol generating material within the cigarette is heated. As a result, there have been active studies on heated cigarettes and heated aerosol-generating devices.

When a heated aerosol-generating device is used, a fastening structure for fastening a member of the heated aerosol-generating device is exposed to the outside, and may be damaged by external pressure or stimulus. In addition, when the user arbitrarily disassembles or disassembles the exposed fastening structure of the aerosol-generating device, this may be a cause of failure of the aerosol-generating device.

The prior fastening structure is configured to be exposed or hidden to the outside in the appearance of the aerosol-generating device, but can be easily disassembled by the user due to the simple structure of the hidden fastening structure. To prevent breakage or damage of the aerosol-generating device to improve durability, it is necessary to conceal the fastening member so that the fastening structure of the aerosol-generating device is not exposed to the outside.

In addition, in the structure of the aerosol-generating device, when the user breaks or damages the aerosol-generating device by arbitrary decomposition, it is impossible to confirm whether or not the aerosol-generating device is arbitrarily decomposed.

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

Referring to fig. 1, the aerosol-generating device 100 includes a battery 110, a control unit 120, and a heater 130. Referring to fig. 2 and 3, the aerosol-generating device 100 further comprises a vaporizer 140. Additionally, the cigarette 200 may be inserted into the interior space of the aerosol-generating device 100.

The aerosol-generating device 100 shown in figures 1 to 3 shows only the components relevant to the present embodiment. Accordingly, persons of ordinary skill in the art to which the present embodiments relate will appreciate that the aerosol-generating device 100 may also include other conventional components in addition to those shown in fig. 1-3.

In fig. 2 and 3, the aerosol-generating device 100 is shown to include the heater 130, but the heater 130 may be omitted as necessary.

As shown in fig. 1, battery 110, control unit 120, and heater 130 are arranged in a row. As shown in fig. 2, the battery 110, the control unit 120, the vaporizer 140, and the heater 130 are arranged in a row. As shown in fig. 3, vaporizer 140 and heater 130 are arranged in parallel. However, the internal structure of the aerosol-generating device 100 is not limited to the structure shown in fig. 1 to 3. In other words, the arrangement of the battery 110, the control unit 120, the heater 130, and the vaporizer 140 may be changed according to the design of the aerosol-generating device 100.

If a cigarette 200 is inserted into the aerosol-generating device 100, the aerosol-generating device 100 may operate the heater 130 and/or the vaporizer 140 to produce an aerosol from the cigarette 200 and/or the vaporizer 140. The aerosol generated by heater 130 and/or vaporizer 140 passes through cigarette 200 and is delivered to the user.

The aerosol-generating device 100 may heat the heater 130 if desired even if the cigarette 200 is not inserted in the aerosol-generating device 100.

The battery 110 supplies power for operating the aerosol-generating device 100. For example, the battery 110 may supply power to heat the heater 130 or the vaporizer 140, and may supply power required for operation to the control part 120. In addition, the battery 110 may supply power necessary for operation to a display, a sensor, a motor, and the like provided in the aerosol-generating device 100.

The control unit 120 controls the operation of the aerosol-generating device 100 as a whole. Specifically, the control unit 120 controls operations of other components included in the aerosol-generating device 100, in addition to the battery 110, the heater 130, and the vaporizer 140. The control unit 120 may check the state of each component of the aerosol-generating device 100 to determine whether the aerosol-generating device 100 is operable.

The control section 120 includes at least one processor. The processor may be constituted by a plurality of logic gate arrays, or may be realized 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.

Heater 130 may be heated by power supplied from battery 110. For example, when a cigarette is inserted into the aerosol-generating device 100, the heater 130 may be located on the exterior of the cigarette. Thus, the heated heater 130 can raise the temperature of the aerosol generating substance in the cigarette.

Heater 130 may be a resistive heater. For example, heater 130 may include a conductive track (track) where heater 130 is heated when current flows. However, heater 130 is not limited to the above example, and is not particularly limited as long as it can be heated to a desired temperature. Here, the desired temperature may be preset at the aerosol-generating device 100, or the desired temperature may be set by the user.

In another example, heater 130 may be an induction heating heater. Specifically, heater 130 may include a conductive coil for inductively heating a cigarette, which may include a heat conductor (heater) capable of being heated by an inductively heated heater.

For example, the heater 130 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 200 according to the shape of the heating member.

In addition, the aerosol-generating device 100 may be provided with a plurality of heaters 130. At this time, the plurality of heaters 130 may be provided to be inserted into the inside of the cigarette 200, and may be provided at the outside of the cigarette 200. In addition, some of heaters 130 may be provided so as to be inserted into cigarette 200, and other heaters may be provided outside cigarette 200. The shape of heater 130 is not limited to the shape shown in fig. 1 to 3, and may be formed in various other shapes.

The vaporizer 140 may heat the liquid composition to generate an aerosol, which may be delivered to a user via the cigarette 200. In other words, the aerosol generated by the vaporizer 140 is movable along the airflow path of the aerosol-generating device 100, which may be configured to deliver the aerosol generated by the vaporizer 140 to the user via the cigarette.

For example, the vaporizer 140 may include a liquid storage part, a liquid delivery unit, and a heating part, but is not limited thereto. For example, the liquid storage, the liquid delivery unit, and the heating component may be included as separate modules in the aerosol-generating device 100.

The liquid storage portion can store a liquid composition. For example, the liquid composition may be a liquid containing a tobacco-containing substance containing a volatile tobacco flavor component, and may also be a liquid containing a non-tobacco substance. The liquid storage part may be formed to be detachable from or attachable to the vaporizer 140, or may be formed integrally with the vaporizer 140.

For example, the liquid composition may include water, solvents, ethanol, plant extracts, flavors, fragrances, or vitamin mixtures. The flavoring agent may include menthol, peppermint, spearmint oil, various fruit flavor components, and the like, but is not limited thereto. The flavoring agent may include ingredients that provide a variety of flavors or fragrances 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. In addition, the liquid composition may include an aerosol former such as glycerin or propylene glycol.

The liquid transfer unit can transfer the liquid composition in the liquid storage portion to the heating member. For example, the liquid transfer unit may be a core (wick) such as cotton fiber, ceramic fiber, glass fiber, porous ceramic, but is not limited thereto.

The heating member is a member for heating the liquid composition conveyed by the liquid conveying unit. For example, the heating member may be a metal hot wire, a metal hot plate, a ceramic heater, etc., but is not limited thereto. In addition, the heating member may be constituted by a conductive heating wire such as a nichrome wire, and may be provided in a configuration wound around the liquid transfer unit. The heating member may be heated by the supplied electric current and may heat the liquid composition by transferring heat to the liquid composition in contact with the heating member. As a result, aerosol can be generated.

For example, the vaporizer 140 may also be referred to as an electronic cigarette (cartomizer) or an atomizer (atommizer), but is not limited thereto.

In one aspect, the aerosol-generating device 100 may also include other common components in addition to the battery 110, the control 120, the heater 130, and the vaporizer 140. For example, the aerosol-generating device 100 may include a display capable of outputting visual information and/or a motor for outputting tactile information. Additionally, the aerosol-generating device 100 may include at least one sensor (puff detection sensor, temperature detection sensor, cigarette insertion detection sensor, etc.). In addition, the aerosol-generating device 100 can be configured to allow the inflow of outside air or the outflow of inside air even when the cigarette 200 is inserted.

Although not shown in fig. 1 to 3, the aerosol-generating device 100 may constitute a system together with another cradle. For example, the cradle may be used for charging of the battery 110 of the aerosol-generating device 100. Alternatively, the heater 130 may heat in a state where the cradle is coupled to the aerosol-generating device 100.

The cigarette 200 may be a cigarette similar to a conventional combustion type cigarette. For example, the cigarette 200 may be divided into a first portion comprising the aerosol-generating substance and a second portion comprising a filter or the like. Alternatively, the second portion of the cigarette 200 may also comprise an aerosol generating substance. For example, an aerosol-generating substance made in the form of particles or capsules may be inserted into the second portion.

The interior of the aerosol-generating device 100 may be inserted through the entire first portion and the second portion may be exposed to the exterior. Alternatively, the aerosol-generating device 100 may be inserted into a portion of the first portion, or may be inserted into the entirety of the first portion and a portion of the second portion. The user may inhale the aerosol while holding the second portion in the mouth. At this time, the external air generates aerosol while passing through the first portion, and the generated aerosol is delivered to the user's mouth via the second portion.

As an example, the external air may flow in through at least one air passage formed in the aerosol-generating device 100. For example, the opening and closing of the air passage formed in the aerosol-generating device 100 and/or the size of the air passage may be adjusted by the user. Thus, the user can adjust the atomization amount, the smoking feeling, and the like. As another example, the external air may also flow into the interior of the cigarette 200 through at least one hole (hole) formed in the surface of the cigarette 200.

Next, an example of the cigarette 200 will be described with reference to fig. 4.

Fig. 4 is a diagram showing an example of a cigarette.

Referring to fig. 4, a cigarette 200 includes a tobacco rod 210 and a filter rod 220. As described with reference to fig. 1-3, the first portion 210 comprises a tobacco rod 210 and the second portion 220 comprises a filter rod 220.

The filter rod 220 shown in fig. 4 is a single segment structure, but is not limited thereto. In other words, the filter rod 220 may be constructed of multiple segments. For example, the filter rod 220 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 220 may also include at least one section that performs other functions, as desired.

The cigarette 200 may be wrapped with at least one wrapper 240. The packing paper 240 may be formed with at least one hole (hole) through which external air flows in or internal gas flows out. As an example, the cigarette 200 may be wrapped with a wrapper 240. As another example, the cigarette 200 may be wrapped with two or more wrapping papers 240. For example, the tobacco rod 210 may be wrapped with a first wrapper and the filter rod 220 may be wrapped with a second wrapper. Also, the tobacco rod 210 and the filter rod 220 wrapped with a single wrapper may be combined, and the whole cigarette 200 may be repacked with a third wrapper. If the tobacco rod 210 or filter rod 220 is constructed from a plurality of segments, respectively, the segments may be individually wrapped with a single wrapper. Further, the entire cigarette 200 formed by combining the segments each wrapped with a single wrapping paper may be repackaged with another wrapping paper.

The tobacco rod 210 comprises 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, the tobacco rod 210 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 210 so as to be sprayed on the tobacco rod 210.

The tobacco rod 210 can be made in a variety of ways. For example, the tobacco rod 210 may be made from sheet (sheet) material or from strand (strand) material. Alternatively, the tobacco rod 210 may be made from tobacco leaves obtained by cutting tobacco pieces into small pieces. Additionally, the tobacco rod 210 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 material surrounding the tobacco rod 210 can uniformly disperse the heat transferred to the tobacco rod 210, thereby increasing the heat conductivity applied to the tobacco rod, and thus improving the taste of tobacco. In addition, the heat conductive substance surrounding the tobacco rod 210 can function as a heat sensitive body heated by the induction heating type heater. At this time, although not shown in the drawings, the tobacco rod 210 may include other heat-sensitive bodies in addition to the heat-conductive substance surrounding the outside.

The filter rod 220 may be a cellulose acetate filter. In one aspect, the shape of the filter rod 220 is not limited. For example, the filter rod 220 may be a cylindrical (type) rod, or may be a tubular (type) rod having a hollow interior. In addition, the filter rod 220 may be a semi-concealed (receive) type (type) rod. If the filter rod 220 is constructed of multiple segments, at least one of the multiple segments may be made in different shapes.

The filter rod 220 may be made to generate a scent. For example, the filter rod 220 may be sprayed with a flavored liquid, or fibers coated with a flavored liquid may be inserted into the filter rod 220.

Additionally, the filter rod 220 may include at least one capsule 230. Here, the capsule 230 can perform a function of generating a flavor as well as a function of generating an aerosol. For example, the capsule 230 may be a structure in which a liquid containing a perfume is enclosed by a film. The capsule 230 may have a spherical or cylindrical shape, but is not limited thereto.

If the filter rod 220 includes a section for cooling the aerosol, the cooling section may be made of a high molecular substance or a biodegradable high molecular substance. For example, the cooling section 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 section is not limited to the above example, and is not particularly limited as long as the function of cooling the aerosol can be performed.

In one aspect, although not shown in FIG. 4, the cigarette 200 of an embodiment may also include a front end filter. The front filter is located on the opposite side of the tobacco rod 210 from the filter rod 220. The tip filter can prevent the tobacco rod 210 from being detached to the outside, and can prevent liquefied aerosol from flowing from the tobacco rod 210 into the aerosol-generating device (100 of fig. 1 to 3) during smoking.

Fig. 5a is an exploded view of an aerosol-generating device of an embodiment, and fig. 5b is a perspective view of the aerosol-generating device of the embodiment shown in fig. 5 a.

The aerosol-generating device 100 of the embodiment shown in fig. 5a and 5b may comprise a first shield 10, a second shield 20, a fastening portion 50 and a housing 80.

The first cover 10 of the aerosol-generating device 100 has an opening 11 that is open on one side, and can accommodate a cigarette 200 (see fig. 1) inserted through the opening 11. The first shield 10 also has an inner space capable of accommodating an inserted cigarette, and the inner space may have a heater 130 (refer to fig. 1) for heating the cigarette.

The aerosol-generating device 100 may comprise a second shield 20 joined at the other side of the first shield 10. The second shield 20 may be coupled to the first shield 10 at the side opposite to the side where the cigarette is inserted, i.e., the other side of the first shield 10.

The second shield 20 may include a control portion 120 (refer to fig. 4) inside the second shield 20. The second shield 20 may further include a button 27 on one side of the second shield 20, which is connected with the control part to send a signal to the control part 120.

The aerosol-generating device 100 may comprise a fastening portion 50 joining the first and

second shrouds

10, 20. The second shield 20 is coupled to the other side of the first shield 10 by a fastening portion 50 and may contact at least a portion of the first shield 10.

The aerosol-generating device 100 may also include a battery 110 in combination with the second shroud 20. The battery 110 may be combined with one side of the second shield 20 and may be positioned at the other side of the first shield 10. The battery 110 may be shaped like a side surrounding the second shield 20, but is not limited thereto. The battery 110 may be further combined with the second shield 20 to constitute one body, and may supply power to the second shield 20 to operate a control portion inside the second shield 20.

The aerosol-generating device 100 may comprise a second shield 20, a fastening portion 50 and a housing 80 that houses a battery 110 therein and is joined with the second shield 20. When the case 80 accommodates all of the second cover 20, the fastening portion 50, and the battery 110 therein, the second cover 20, the fastening portion 50, and the battery 110 are prevented from being exposed to the outside and can be hidden by the case 80.

Since the fastening portion 50 where the first shield 10 and the second shield 20 are joined is hidden by the case 80, a user of the aerosol-generating device 100 cannot release or separate the joined first shield 10 and second shield 20 by a general operation, and thus breakage of the aerosol-generating device 100 can be prevented.

Referring to fig. 5a and 5b, the fastening portion 50 of the aerosol-generating device 100 of an embodiment may be understood in further detail.

The first shield 10 of the aerosol-generating device 100 may comprise a flange 18 formed at the other end of the first shield 10. The flange 18 may extend in the circumferential direction at the other side end portion of the first shield 10, and may also protrude in the circumferential direction at the other side end portion of the first shield 10 to form a stepped portion.

The fastening portion 50 may include: a first groove portion 15 protruding from the flange 18 toward the second shield 20; a second groove portion 25 corresponding to the first groove portion 15 and formed in the second shield 20; and a fastening unit 28 for fastening the first groove portion 15 and the second groove portion 25.

The first groove portion 15 protrudes from the flange 18 toward the second shield 20, so that the first groove portion 15 may be located on an outer surface of the second shield 20 when the first shield 10 and the second shield 20 are combined.

The second groove portion 25 may be formed at the second shield 20 to correspond to the position of the first groove portion 15. For example, the first and

second groove portions

15 and 25 may have the same central axis when coupled, and thus the fastening unit 28 can pass through the first and

second groove portions

15 and 25 at the same time.

The first groove portion 15 may be plural, for example, the first groove portion 15 may be formed on the flange 18 of the first shield 10 symmetrically with respect to the center of the flange 18, which is the center with respect to the circumferential direction of the first shield 10. The second groove portion 25 may be plural to correspond to the first groove portion 15, and may be formed at a position in the second shield 20 where the first groove portion 15 extends. When a plurality of the first groove portions 15 and the second groove portions 25 are provided, the first groove portions 15 and the second groove portions 25 may be provided at intervals from each other in the extending direction of the flange 18.

The fastening unit 28 may fasten the first and

second groove parts

15 and 25 by the first and

second groove parts

15 and 25, and the fastening unit 28 may be, for example, a pin, a screw, or a rivet. The first and

second groove portions

15 and 25 can be combined with the fastening unit 28, and the size or shape may vary depending on the fastening unit 28.

For example, when the fastening unit 28 is a screw, the first groove portion 15 and the second groove portion 25 may have a bolt shape inside the first groove portion 15 and the second groove portion 25, respectively, so as to accommodate the screw as the fastening unit 28.

When the first and

second shields

10 and 20 are combined by the fastening unit 28 fastening the first and

second groove parts

15 and 25, the heater 130 in the first shield 10 may be electrically connected with the control part 120 in the second shield 20. Thus, the heater 130 of the first shield 10 may be controlled by the control part 120 of the second shield 20.

When a user smokes, the user can press the button 27 formed on one surface of the second hood 20 and capable of sending a signal to the control unit 120, and operate the aerosol-generating device 100.

Fig. 6a is an exploded view of another embodiment of an aerosol-generating device, and fig. 6b is a perspective view of the embodiment of the aerosol-generating device shown in fig. 6 a.

Referring to fig. 6a and 6b, the fastening portion 50 of the aerosol-generating device 100 according to another embodiment can be understood in further detail.

The first shield 10 of the aerosol-generating device 100 may comprise a flange 18 formed at the other end of the first shield 10. The fastening portion 50 may include: a hook 65 extending from the flange 18 and extending toward the second shroud 20; and an accommodating portion 75 formed at the second shield 20 for accommodating the hook portion 65.

The hook portion 65 protrudes from the flange 18 of the first shield 10 toward the second shield 20, so that the hook portion 65 may be located on the outer surface of the second shield 20 when the first shield 10 and the second shield 20 are combined.

Alternatively, the hook part 65 protrudes toward the inside of the second shield 20, so that the hook part 65 may be located on the inner surface of the second shield 20 when the first shield 10 and the second shield 20 are combined.

The hook 65 may have a hook-shaped protrusion at the end of the hook 65, but the embodiment is not limited by the specific structure of the hook 65.

For example, the distal end of the hook part 65 is located on the outer surface of the second shield 20, and the protrusion of the hook part 65 may be a hook-shaped protrusion extending in the direction of the outer surface of the second shield 20. The hook part 65 can be coupled with a receiving part 75 formed on the outer surface of the second shield 20 by a hook-shaped protrusion.

As another example, the hook portion 65 may extend toward the inside of the second shield 20 so as to be coupled with the inner surface of the second shield 20. The protrusion formed at the end of the hook 65 is hook-shaped and may extend toward the inner surface of the second shield 20.

The protrusion formed at the tip of the hook 65 may be directly fastened with the receiving portion 75 formed inside the second shield 20. When a force of a predetermined range or more is applied, the hook 65 housed in the housing 75 of the second hood 20 can be disengaged from the second hood 20.

The receiving portion 75 formed at the second shield 20 may be formed at an outer surface or an inner surface of the second shield 20 so as to correspond to the hook portion 65 of the first shield 10. The receiving portion 75 may have a shape of a protrusion receiving the tip of the hook 65. For example, when the protruding portion of the tip of the hook 65 is hook-shaped, the receiving portion 75 may have a shape capable of fastening with the hook. In addition, when the hook portion 65 of the first shield 10 and the receiving portion 75 of the second shield 20 are coupled inside the second shield 20, the hook portion 65 and the receiving portion 75 can be hidden from the outside.

Figure 7a is a perspective view of an aerosol-generating device 100 of an embodiment in which the housing 80 is incorporated.

Referring to fig. 7a, the aerosol-generating device 100 may comprise the second shield 20 of the aerosol-generating device 100, a battery 110 and a housing 80 that accommodates the fastening portion 50 therein and is joined with the second shield 20.

The case 80 may have a hollow inside to accommodate the second shield 20, the battery 110, and the fastening part 50 inside. The inner cavity accommodates the second cover 20, the battery 110, and the fastening portion 50, thereby preventing the second cover 20, the battery 110, and the fastening portion 50 from being exposed.

By preventing the fastening portion 50 from being exposed, the user of the aerosol-generating device 100 can be prevented from performing a normal operation on the fastening portion 50. This prevents the user of the aerosol-generating device 100 from releasing or disassembling the aerosol-generating device 100 by a general operation method, and thus prevents the aerosol-generating device 100 from being disassembled arbitrarily.

The housing 80 may be coupled with the second shroud 20 by a coupling 88. At this time, the combining portion 88 may include: a first coupling port 29 formed in one surface of the second cover 20; a second coupling port 85 corresponding to the first coupling port 29 and formed at the housing 80; and a coupling unit 86 for coupling the first coupling port 29 and the second coupling port 85.

The first coupling port 29 may be formed at the other side surface of the second shield 20. The first coupling port 29 may be formed in plural on the other side surface of the second shield 20, and for example, may be two symmetrical grooves disposed to be symmetrical with respect to the center of the other side surface of the second shield 20.

The second coupling port 85 may be formed at the other side surface of the case 80 at a position corresponding to the first coupling port 29 of the second shield 20 when the case 80 receives the second shield 20, the fastening part 50 and the battery 110 and is coupled to the second shield 20. For example, the first coupling port 29 and the second coupling port 85 may have the same central axis when the housing 80 is coupled, and thus the coupling unit 86 can simultaneously pass through the first coupling port 29 and the second coupling port 85.

The coupling unit 86 may fasten the first coupling port 29 and the second coupling port 85 through the first coupling port 29 and the second coupling port 85, and the coupling unit 86 may be, for example, a pin, a screw, or a rivet. The first and

second coupling ports

29 and 85 can be coupled with the coupling unit 86, and the size or shape may vary depending on the coupling unit 86.

For example, when the coupling unit 86 is a screw, the first coupling port 29 and the second coupling port 85 may have a shape including a bolt inside the first coupling port 29 and the second coupling port 85, respectively, so as to receive the screw as the coupling unit 86.

The housing 80 may include a through hole 83 formed at one side of the second shield 20 to expose the button 27 to the outside. The through-hole 83 may be formed in a position or shape corresponding to the button 27, and may be formed at one side of the housing 80.

Since the push button 27 can be exposed to the outside through the through hole 83, the user can easily perform a general operation. The button 27 is electrically connected to the control unit 120 inside the second cover 20, and can operate the control unit 120. Therefore, the user can operate the aerosol-generating device 100 by the button 27 when smoking.

Fig. 7b is a diagram illustrating an aerosol-generating device 100 further comprising an embodiment of the outer cover 30 and the cap 90.

The aerosol-generating device 100 may further comprise a cap 90 disposed outside the first shield 10 of the aerosol-generating device 100 and surrounding the first shield 10 with an end in contact with the flange 18. The cap 90 may have an internal cavity that accommodates the first shroud 10 inside. When the cap 90 surrounds the first shield 10 and is bonded to the aerosol-generating device 100, the end of the cap 90 is able to contact the flange 18 of the aerosol-generating device 100.

The cap 90 accommodates the first shield 10 inside and engages with the flange 18 of the first shield 10 to enable separation by external force of a user of the aerosol-generating device 100. At this time, the cap 90 can be easily separated from the first shield 10 by an external force of a user. The first shield 10 and the cap 90 may include a coupling unit that acts as an attractive force to each other.

Although the coupling unit may be easily separated by an external force of a user of the aerosol-generating device 100, it is also possible to provide an attractive force between the first shield 10 and the cap 90 over a prescribed range so as not to be separated by a general impact from the outside. The coupling unit may be, for example, a magnet, but is not limited thereto.

The cap 90 may accommodate the first shield 10 inside, and prevent foreign materials from the outside from entering the first shield 10, and prevent breakage or damage of the first shield 10. When the cap 90 is bonded to the aerosol-generating device 100, the outer side surface of the cap 90 and the outer side surface of the housing 80 are continuous and in engagement with each other, thereby forming the appearance of the aerosol-generating device 100. Thus, the aerosol-generating device 100 can have an integrated smooth outer shape, and portability of the aerosol-generating device 100 can be improved.

The aerosol-generating device 100 may further comprise an outer cover 30 disposed on one face of the housing 80 to cover the junction 88 joining the second shield 20 and the housing 80. The cover 30 covers the combining portion 88 combining the second shield 20 and the case 80, thereby preventing the combining portion 88 from being exposed to the outside. This prevents the user of the aerosol-generating device 100 from operating the joint 88 in a normal manner. By preventing the joint 88 from being operated normally, the user of the aerosol-generating device 100 can be prevented from releasing or disassembling it arbitrarily.

In addition, the aerosol-generating device 100 may further comprise an adhesive 35 between a face of the housing 80 and the outer cover 30. Both surfaces of the adhesive part 35 may be coated with an adhesive substance, and the cover 30 may be coupled to the case 80 through the adhesive part 35.

When the adhesive portion 35 is separated from the adhesive portion 35 after the members of the aerosol-generating device 100 such as the cover 30 are bonded to the adhesive portion 35, at least a portion of the adhesive portion 35 may be deformed in order to show that the cover 30 is separated from the case 80.

For example, when the user arbitrarily separates the cover 30 of the aerosol-generating device 100 from the aerosol-generating device 100, the predetermined mark may remain on the adhesive portion 35 in order to show that the cover 30 is separated from the aerosol-generating device 100.

The marking of the adhesive portion 35 is generated as at least a portion of the adhesive portion 35 is deformed when the cover 30 is separated. For example, when the outer cover 30 is separated, the adhesive substance of the adhesive portion 35 is deformed, or a part or the whole of the adhesive portion 35 is wrinkled or torn together with the adhesive substance, thereby producing the mark of the adhesive portion 35.

The mark left on the adhesive portion 35 is irreversible, and when the mark occurs on the adhesive portion 35, the mark cannot be removed from the adhesive portion 35. Thus, separation information about the outer cover 30 of the aerosol-generating device 100 can be provided by the adhesive portion 35.

By means of the information about any separation of the outer cover 30 of the aerosol-generating device 100, information can be provided about whether at least one of the first shield 10, the second shield 20 and the battery 110 of the aerosol-generating device 100 is separated.

The aerosol-generating device 100 has a structure in which a fastening structure for fastening members of the aerosol-generating device 100 is hidden, and therefore, it is possible to prevent a problem that the fastening structure is exposed to the outside and damaged by pressure or stimulus from the outside.

In addition, it is also possible to prevent breakage or damage of the aerosol-generating device 100 that occurs when a user arbitrarily decomposes or releases the fastening structure of the exposed aerosol-generating device 100.

When the cover 30 is detached from the adhesive portion 35, the adhesive portion 35 of the cover 30 incorporating the aerosol-generating device may leave an irreversible mark. The indicia cannot be removed from the adhesive 35 after leaving the adhesive 35, thereby enabling information to be provided by the adhesive 35 regarding any separation of the outer cover 30 of the aerosol-generating device 100.

The method of manufacturing the aerosol-generating device 100 of the embodiment comprises: a step of providing a first shield 10, the first shield 10 including an opening 11 at an upper portion, a heater 130 capable of being inserted into an inner space of the cigarette 200 through the opening 11, the heater being located in the inner space; a step of coupling the second shield 20 including the control part 120 to the lower portion of the first shield 10; a step of coupling the first shield 10 and the second shield 20 by the fastening part 50; a step of coupling the battery 110 to the second shield 20; and a step of coupling the case 80 and the second shield 20 so as to accommodate the second shield 20, the fastening part 50, and the battery 110 therein.

At this time, the housing 80 can prevent the fastening portion 50 from being exposed to the outside.

The structure and effects of the method of manufacturing the aerosol-generating device 100 of the embodiment are the same as those of the aerosol-generating device 100 described above, and therefore detailed description of overlapping ranges will be omitted.
