Description

TECHNICAL FIELD

The present disclosure relates to an aerosol generating source support assembly and an aerosol generating apparatus having the aerosol generating source support assembly, and more particularly, to an aerosol generating source support assembly that is easy to clean and an aerosol generating apparatus having the aerosol generating source support assembly.

BACKGROUND ART

In recent years, there is increasing demand for an apparatus (i.e., an aerosol generating apparatus) for heating a cigarette to generate an aerosol from components in the cigarette. In an aerosol generating apparatus including a heater for heating a cigarette, the cigarette may be separated from the aerosol generating apparatus after use of the cigarette and a new cigarette may be inserted into the aerosol generating apparatus.

The aerosol generating apparatus has to be kept clean in order to generate a high-quality aerosol even after the aerosol generating apparatus is repeatedly used. However, debris may accumulate inside the aerosol generating apparatus while the cigarette is heated to generate the aerosol. The accumulated debris may contaminate the aerosol generating apparatus, thus degrading its performance and causing discomfort and inconvenience for a user.

In general, the cleaning of the inside of the aerosol generating apparatus is performed in a manner in which, while holding the aerosol generating apparatus by hand, the user points a cigarette insertion hole toward the ground and shakes the aerosol generating apparatus. However, since debris stuck inside the aerosol generating apparatus are not easily discharged from the aerosol generating apparatus, the user has to tap the cigarette insertion hole of the aerosol generating apparatus against a hard surface such as a table to remove the debris, and thus, cleaning is inconvenient and there is a risk of breaking a case.

In addition, when the aerosol generating apparatus is repeatedly used for a long time, debris may get stuck to an inner area of the aerosol generating apparatus which is not exposed to the outside through the cigarette insertion hole. In order to clean the inner area which is not exposed to the outside of the aerosol generating apparatus, only a special tool such as a screwdriver can be used to forcibly disassemble some parts thereof. In this light, it is difficult to clean the aerosol generating apparatus.

FIG. 1 is a perspective view illustrating an aerosol generating apparatus with an aerosol generating source support assembly according an exemplary embodiment.

The aerosol generating source support assembly and aerosol generating apparatus according to the exemplary embodiment shown in FIG. 1 may include a case 1001 and a cover 1002. The cover 1002 is coupled with a first end of the case 1001, and thus the cover 1002 constitutes the outer appearance of the aerosol generating apparatus together with the case 1001.

The case 1001 constitutes the outer appearance of the aerosol generating apparatus 1 and functions to accommodate various components in a space formed therein, thereby protecting them.

The cover 1002 and the case 1001 may include a plastic material with low heat conductivity or a metal coated with a heat barrier material on its surface. The cover 1002 and the case 1001 may be fabricated through, for example, an injection molding method, a 3D printing method, or a method of assembling small parts fabricated through injection molding.

A locking device may be installed between the cover 1002 and the case 1001 to maintain the coupling between the cover 1002 and the case 1001. The locking device may include, for example, a protrusion and a groove. The coupling between the cover 1002 and the case 1001 may be maintained while the protrusion is inserted in the groove. The protrusion may be moved separated from the groove when a use presses a manipulation button.

The locking device may also include, for example, a magnet and a metal member that is attracted to the magnet. When a magnet is used for the locking device, a magnet may be installed on either the cover 1002 or the case 1001 and a metal that is attracted to the magnet may be attached to the other one. Alternatively, magnets may be installed on both the cover 1002 and the case 1001.

In the aerosol generating apparatus according to the exemplary embodiment shown in FIG. 1, the cover 1002 is not an essential configuration. Thus, the cover 1002 may not be installed as necessary.

An outside hole 1002p through which the cigarette 3 may be inserted is formed on the top surface of the cover 1002 coupled with the case 1001. Also, a rail 1003r is formed on the top surface of the cover 1002 at a position adjacent to the outside hole 1002p. A door 1003 that is capable of sliding along the top surface of the cover 1002 is installed on the rail 1003r. The door 1003 may slide in a straight line along the rail 1003r.

As the door 1003 moves along the rail 1003r in the direction indicated by the arrow in FIG. 1, the outside hole 1002p and an insertion hole 1004p that enable the cigarette 3 to be inserted into the case 1001 through the cover 1002 are exposed to the outside. The outside hole 1002p of the cover 1002 exposes the insertion hole 1004p of an accommodating path 1004h for accommodating the cigarette 3 to the outside.

When the outside hole 1002p is exposed to the outside by the door 1003, a user may insert an end portion 3b of the cigarette 3 into the outside hole 1002p and the insertion hole 1004p, thereby placing the cigarette 3 in the accommodating path 1004h formed inside the cover 1002.

In the exemplary embodiment, the door 1003 is installed to move in a straight line with respect to the cover 1002. However, the exemplary embodiment is not limited by the structure in which the door 1003 is coupled with the cover 1002. For example, the door 1003 may be rotatably mounted on the cover 1002 through a hinge assembly. In case of employing a hinge assembly, the door 1003 may be rotated toward a side of the outside hole 1002p along an extension of the top surface of the cover 1002. Otherwise, the door 1003 may be rotated in a direction away from the top surface of the cover 1002.

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

At the case 1001, a button 1009 is provided. As the button 1009 is manipulated, the operation of the aerosol generating apparatus may be controlled.

An outside air introduction gap 1002g that allows air to flow into the interior of the cover 1002 is formed at a portion between the cover 1002 and the case 1001 when the cover 1002 is coupled with the case 1001.

FIG. 2 is a perspective view illustrating an operating state in which some components are separated from the aerosol generating apparatus according to the exemplary embodiment shown in FIG. 1. FIG. 3 is a perspective view illustrating an operating state in which some components are separated from the aerosol generating apparatus according to the exemplary embodiment shown in FIG. 2. FIG. 4 is a side cross-sectional view illustrating some components in the aerosol generating apparatus according to the exemplary embodiment shown in FIG. 2.

As shown in FIG. 4, in a state where the cigarette 3 is inserted in the aerosol generating apparatus, the user may hold the cigarette 3 by mouth and inhale aerosol.

When the use of the cigarette 3 is terminated, the user may perform a cleaning operation for removing a tobacco material, which may remain in the aerosol generating apparatus, after separating the cigarette 3 from the aerosol generating apparatus.

The cleaning of the aerosol generating apparatus may be performed in a manner that the user separates the cover 1002 from the case 1001 of the aerosol generating apparatus, separates an aerosol generating source support assembly 4 from the case 1001 to expose an internal space of the aerosol generating apparatus and the heater to the outside, and removes the tobacco material.

Referring to FIG. 2, the cover 1002 may be coupled to an end portion 1001a of the case 1001 to cover the aerosol generating source support assembly 4 coupled to the end portion 1001a of the case 1001. In addition, the cover 1002 may be separated from the case 1001 as necessary.

In order to remove the cigarette 3 from the aerosol generating apparatus after the use of the cigarette 3, the user may pull out the cigarette 3 from the case 1001 while or after rotating the cigarette 3 by hand.

When the cigarette 3 is separated from the case 1001 while or after being rotated, an coupling between the cigarette 3 and the heater may be released, and at the same time, the tobacco material attached to the cigarette 3 may be discharged to the outside of the case 1001 together with the cigarette 3.

When the cigarette 3 is pulled without rotating the cigarette 3 (or even when the cigarette 3 is pulled while the cigarette 3 is being rotated), the cigarette 3 may be separated from the case 1001. However, a portion of the cigarette 3, for example, a tobacco portion, may remain on the heater side without being discharged from the case 1001. In this case, the user may separate the aerosol generating source support assembly 4 from the case 1001, as shown in FIG. 3, after removing the cover 1002 from the case 1001. In this case, the tobacco portion remaining on the heater side is separated from the case 1001 together with the aerosol generating source support assembly 4. Thereafter, the user may remove the tobacco portion remaining in the aerosol generating source support assembly 4 separated from the case 1001.

Referring to FIGS. 3 and 4, the aerosol generating apparatus includes a case 1001, a protrusion tube 1020 which is hollow and protrudes from the end portion 1001a of the case 1001 and has an opening open to the outside, a heater 1030 installed in the case 1001 and positioned inside the protrusion tube 1020, and an aerosol generating source support assembly 4 that may be coupled to the protrusion tube 1020 and be separated from the protrusion tube 1020.

As shown in FIG. 2, when the user grasps and pulls the aerosol generating source support assembly 4 upward while the aerosol generating source support assembly 4 is coupled to the case 1001, the aerosol generating source support assembly 4 may be separated from the case 1001.

The aerosol-generating source support assembly 4 has a pressing knob 20x on the outer side surface of the aerosol generating source support assembly 4, which helps the user lift up the aerosol generating source support assembly 4. In the drawings, the pressing knob 20x protrudes from the outer surface of the aerosol generating source support assembly 4 and has a shape extending by a predetermined distance along the circumferential direction of the aerosol generating source support assembly 4.

However, the configuration of the pressing knob 20x is not limited thereto. For example, the pressing knob 20x may have a groove shape recessed from the outer surface of the aerosol-generating source support assembly 4.

Referring to FIG. 4, the protrusion tube 1020 surrounds and protects the heater 1030, and serves to support the aerosol generating source support assembly 4 when the aerosol generating source support assembly 4 is coupled to the protrusion tube 1020.

Referring to FIG. 3, the protrusion tube 1020 has an inclined protrusion 1020y protruding from the outer surface thereof and extending in an up and down direction, that is, in a moving direction of the aerosol generating source support assembly 4. The inclined protrusion 1020y has an inclination. The aerosol generating source support assembly 4 has an inclined groove 20y that may accommodate the inclined protrusion 1020y to support the inclined protrusion 1020y. At least portions of the surfaces of the inclined protrusion 1020y and the inclined groove 20y may form curved surfaces curved along the moving direction of the aerosol generating source support assembly 4. As the inclined protrusions 1020y and the inclined grooves 20y have the curved surfaces, the aerosol generating source support assembly 4 may be smoothly mounted or separated from the protrusion tube 1020.

Since a state in which the inclined protrusion 1020y is inserted in the inclined groove 20y is stably maintained while the aerosol generating source support assembly 4 is mounted on the protrusion tube 1020, the aerosol generating source support assembly 4 is not easily separated from the protrusion tube 1020 until the user pulls the aerosol generating source support assembly 4.

The installed positions of the inclined groove 20y and the inclined protrusion 1020y are not limited thereto. For example, the inclined groove 20y may be installed in the protrusion tube 1020 and the inclined protrusion 1020y may be installed in the aerosol generating source support assembly 4.

Since the protrusion tube 1020 is hollow and has a coupling passage 1020h into which at least a portion of the aerosol generating source support assembly 4 may be inserted. The upper end of the coupling passage 1020h is open to the outside in the upward direction of the aerosol generating apparatus.

The case 1001 is provided with a heater 1030 for heating the cigarette 3. The heater 1030 is installed in the case 1001 such that an upper end portion of the heater 1030 is positioned inside the protrusion tube 1020. When the cigarette 3 is accommodated in the aerosol generating source support assembly 4 in a state in which the aerosol generating source support assembly 4 is coupled to the protrusion tube 1020, the upper end portion of the heater 1030 is inserted into the bottom of an end portion of the cigarette 3.

The heater 1030 is electrically connected to a power supply device arranged inside the case 1001. When power is supplied from the power supply device to the heater 1030 in a state in which the cigarette 3 is inserted in the end portion of the heater 1030, the heater 1030 is heated and heats the cigarette 3.

Referring to FIG. 4, the aerosol generating source support assembly 4 may be inserted into the coupling passage 1020h inside the protrusion tube 1020 through the opening of the protrusion tube 1020. The aerosol generating source support assembly 4 has an inner cylinder 10 and an outer cylinder 20 for movably supporting the inner cylinder 10.

Referring to FIG. 4, the outer cylinder 20 of the aerosol generating source support assembly 4 has an extended support surface 26 protruding inward and spaced apart from an outer wall 20t having a substantially semi-cylindrical shape. When the aerosol generating source support assembly 4 is coupled to the protrusion tube 1020, the protrusion tube 1020 is inserted between the outer wall 20t and the extended support surface 26, and thus, a coupling state between the aerosol generating source support assembly 4 and the protrusion tube 1020 may be stably maintained.

According to the stable coupling structure between the aerosol generating source support assembly 4 and the protrusion tube 1020 as described above, even if external vibration due to an impact is applied to the aerosol generating apparatus, the separation or breakage of the components of the aerosol generating apparatus may be reduced. This may ensure good durability and stability even if the aerosol generating apparatus is used for a long time.

In addition, since the aerosol generating source support assembly 4 may be easily separated from the case 1001 when a cleaning operation is performed, the cleaning operation may be reliably and conveniently performed.

In addition, the protrusion tube 1020 may perform a function of directly supplying outside air to an end portion of the cigarette 3. Referring to FIG. 3, the protrusion tube 1020 has an air hole 1020g connecting the inside and the outside of the protrusion tube 1020, and an air flow path 1020n extending along a surface of the protrusion tube 1020 to guide the flow of air to the air hole 1020g.

A plurality of air holes 1020g may be provided spaced apart in the circumferential direction with respect to the center of the longitudinal direction of the protrusion tube 1020. The air hole 1020g and the air flow path 1020n form a flow passage of air for allowing air outside the protrusion tube 1020 to flow into the protrusion tube 1020.

Referring to FIG. 4, when the aerosol generating source support assembly 4 is coupled to the protrusion tube 1020, the extended support surface 26 of the aerosol generating source support assembly 4 is inserted into the protrusion tube 1020. While the extended support surface 26 of the aerosol generating source support assembly 4 moves downward along the protrusion tube 1020, the heater 1030 located inside the protrusion tube 1020 passes through a heater insertion opening 10b of the aerosol generating source support assembly 4.

With the aerosol generating source support assembly 4 coupled to the protrusion tube 1020, an end portion of the heater 1030 passes through the heater insertion opening 10b of the aerosol generating source support assembly 4 and is located inside the aerosol generating source support assembly 4. Therefore, when the cigarette 3 is accommodated in the aerosol generating source support assembly 4 in a state in which the aerosol generating source support assembly 4 is coupled to the protrusion tube 1020, the end portion of the heater 1030 is inserted into the cigarette 3.

In the exemplary embodiment shown in the drawings, a heater inserted into a cigarette is shown. However, the configuration of the heater is not limited thereto. For example, the heater may be made of a cylindrical film heater that may surround at least a portion of the outer surface of the cigarette. In the case of using a cylindrical film heater, the cylindrical film heater may be installed on the inner wall surface or the outer wall surface of the protrusion tube 1020.

When the user of the aerosol generating apparatus inserts the cigarette 3 into the receiving passage 1004h, the cigarette 3 moves along the aerosol generating source support assembly 4. When the end portion of the cigarette 3 reaches the bottom of the aerosol generating source support assembly 4, a feeling of contact between the bottom and the end portion of the cigarette 3 is transmitted to the user's hand holding the cigarette 3. Therefore, the user may easily mount the cigarette 3 to the aerosol generating apparatus by performing a simple operation of holding the cigarette 3 in the hand and pushing the cigarette 3 into the aerosol generating apparatus.

When the user separates the cigarette 3 from the aerosol generating source support assembly 4, the user may hold the cigarette 3 by hand and rotate it and pull the cigarette 3 out of the aerosol generating source support assembly 4. While the user holds and rotates the cigarette 3 by hand, the cigarette 3 and the heater 1030 attached to each other by the tobacco material may be completely separated.

After separating the cigarette 3 from the aerosol generating source support assembly 4, the user may clean the inside of the aerosol generating source support assembly 4. When the user separates the aerosol generating source support assembly 4 from the case 1001 to perform a cleaning operation, the user may grasp the aerosol generating source support assembly 4 by hand and pull the aerosol generating source support assembly 4 out of the case 1001.

FIG. 6 is a perspective view illustrating some components of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 5. FIG. 7 is a perspective view illustrating an operating state of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 5.

The inner cylinder 10 and the outer cylinder 20 may include a material such as plastic, metal or rubber that is capable of withstanding heat well, or a combination of these materials.

The inner cylinder 10 is hollow and has a support space 15, and has an inner wall surface 11a capable of contacting, surrounding, and supporting at least a portion of the cigarette 3 that is an aerosol generating source.

The outer cylinder 20 is connected to the inner cylinder 10 and rotatably supports the inner cylinder 10. The position of the inner cylinder 10 may be changed between a coupling position in which the inner cylinder 10 is coupled to the outer cylinder 20, as shown in FIG. 5, and a separation position in which at least a portion of the inner cylinder 10 is separated from the outer cylinder 20, as shown in FIG. 7.

The inner cylinder 10 may be rotatably coupled to the outer cylinder 20 to rotate between the coupling position and the separation position. In the coupling position shown in FIG. 5, the inner cylinder 10 is accommodated inside the outer cylinder 20. In the separation position shown in FIG. 6, a portion of the inner cylinder 10 protrudes to the outside of the outer cylinder 20.

The outer cylinder 20 is hollow and has an accommodation space 25 having an empty interior so as to accommodate the inner cylinder 10 in the coupling position. The outer cylinder 20 includes one side opening 20a for opening one end of the accommodation space 25 to the outside in an upward direction, the other side opening 20b for opening the other end of the accommodation space 25 to the outside in a downward direction, and an open passage 27 extending from the other side opening 20b toward the one side opening 20a so as to open a portion of the accommodation space 25 to the outside in a lateral direction.

As shown in FIG. 5, the outer cylinder 20 may include an inclined groove 20y on an inner side surface thereof. The inclined groove 20y serves to accommodate and support the inclined protrusion 1020y of the protrusion tube 1020 shown in FIG. 3.

The inner cylinder 10 has a shaft 12 protruding toward the outer cylinder 20. The outer cylinder 20 has a rotation hole 22 for accommodating the shaft 12 and rotatably supporting the shaft 12.

The inner cylinder 10 is rotatably coupled to the outer cylinder 20 such that the inner cylinder 10 is capable of rotating about the axis L which crosses the extending direction of the outer cylinder 20 toward the other side opening 20b from the one side opening 20a of the outer cylinder 20. When the inner cylinder 10 rotates from the separation position toward the coupling position, at least a portion of the inner cylinder 10 protrudes to the outside of the accommodation space 25 through the open passage 27 of the outer cylinder 20.

Referring to FIG. 6, the inner cylinder 10 has an insertion opening 10a, which opens the support space 15 to the outside in the upward direction, at one end portion of the inner cylinder 10. When the inner cylinder 10 and the outer cylinder 20 are in the coupling position shown in FIG. 5, the insertion opening 10a of the inner cylinder 10 is aligned with the one side opening 20a of the outer cylinder 20, and thus, the insertion opening 10a of the inner cylinder 10 and the one side opening 20a of the outer cylinder 20 form the insertion hole 1004p shown in FIGS. 3 and 4.

Referring to FIG. 7, the inner cylinder 10 has a heater insertion opening 10b opened to the outside from the other end portion in the downward direction. In FIG. 4, when the aerosol generating source support assembly 4 is coupled to the case 1001, an upper end portion of the heater 1030 passes through the heater insertion opening 10b and is positioned inside the aerosol generating source support assembly 4. Therefore, when the cigarette 3 is inserted into the aerosol generating source support assembly 4 through the insertion hole 1004p as shown in FIG. 4, the upper end portion of the heater 1030 is inserted into the bottom of an end portion of the cigarette 3.

The size of the heater insertion opening 10b of the aerosol generating source support assembly 4 may correspond to the thickness of the heater 1030. For example, when the heater 1030 has a circular cross section, the heater insertion opening 10b also has a circular cross-sectional shape, and the inner diameter of the heater insertion opening 10b is formed to correspond to the outer diameter of the heater 1030.

The size of the inner diameter of the heater insertion opening 10b is not limited thereto. For example, the inner diameter of the heater insertion opening 10b may be formed to be larger than the outer diameter of the heater 1030, and thus, the inner surface of the heater insertion opening 10b may be spaced apart from the outer side of the heater 1030.

FIG. 8 is a perspective view illustrating a bottom of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 7.

The inner cylinder 10 has a cut-out hole 16 to open a portion of the support space 15 to the outside for easy cleaning.

In addition, the outer cylinder 20 has the extended support surface 26 protruding from the inner wall surface of the outer cylinder 20 so as to be coupled to the cut-out hole 16 of the inner cylinder 10 in the coupling position where the outer cylinder 20 is coupled to the inner cylinder 10.

When the outer cylinder 20 and the inner cylinder 10 are in the coupling position, the extended support surface 26 may be connected to the inner wall surface 11a of the inner cylinder 10, thereby extending in the circumferential direction in order to contact, surround, and support at least a portion of the cigarette 3. In the coupling position, the extended support surface 26 of the outer cylinder 20 and the inner wall surface 11a of the inner cylinder 10 may form a circular shape corresponding to the cross-sectional shape of the cigarette 3.

The extended support surface 26 of the outer cylinder 20 has a groove 27g extending along the edge of the extended support surface 26. In addition, the cut-out hole 16 of the inner cylinder 10 has a protruding border 17 protruding toward the outer cylinder 20 and extending along the edge of the cut-out hole 16.

When the inner cylinder 10 rotates to the coupling position and is accommodated in the outer cylinder 20, the protruding border 17 of the inner cylinder 10 may be inserted into the groove 27g of the outer cylinder 20, and thus, the coupling position in which the inner cylinder 10 and the outer cylinder 20 are coupled to each other may be stably maintained.

In the aerosol generating source support assembly 4 according to the exemplary embodiment shown in FIG. 8, the inner cylinder 10 has the protruding border 17 and the outer cylinder 20 has the groove 27g. However, exemplary embodiments are not limited by such a configuration. That is, the inner cylinder 10 may have a groove, and the outer cylinder 20 may have a protruding border.

When the cut-out hole 16 of the inner cylinder 10 rotates in a direction to be separated from the extended support surface 26 of the outer cylinder 20 and rotates to a separation position as shown in FIG. 8, the support space 15 of the inner cylinder 10 and the accommodation space 25 of the outer cylinder 20 are exposed to the outside. As such, when the support space 15 and the accommodation space 25 are exposed to the outside, it is possible to reliably and easily remove debris generated while the cigarette 3 generates aerosol and attached to the interior of the aerosol generating source support assembly 4.

The shaft 12 of the inner cylinder 10 has a stopper 12s protruding outward. The outer cylinder 20 has a top plate 23 extending outward from the one side opening 20a.

When the inner cylinder 10 rotates toward the separation position, the top plate 23 may come into contact with the stopper 12s, thereby supporting the stopper 12s to fix a rotation position of the stopper 12s. In other words, when the inner cylinder 10 rotates toward the separation position, the stopper 12s is tightly fitted to the lower surface of the top plate 23, and thus, the top plate 23 and the stopper 12s are in tight contact with each other. Therefore, when the inner cylinder 10 has rotated to the separation position shown in FIGS. 7 and 8, the rotated inner cylinder 10 at the separation position may be stably maintained due to the close contact between the stopper 12s and the top plate 23.

As described above, since the inner cylinder 10 may rotate between the coupling position, in which the inner cylinder 10 is coupled to the outer cylinder 20, and the separation position, in which the inner cylinder 10 rotates with respect to the outer cylinder 20 to be separated from the outer cylinder 20, a cleaning operation may be easily performed. In particular, since the inner cylinder 10 is fixed in the separation position by the action of the stopper 12s, the user may easily perform a cleaning operation in a state where the aerosol generating source support assembly is maintained in the separation position as shown in FIGS. 7 and 8.

MODE OF DISCLOSURE

FIG. 9 is a perspective view of an aerosol generating source support assembly according to another exemplary embodiment.

The aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 9 includes an inner cylinder 10 which is hollow and has an empty interior, and an outer cylinder 20 rotatably supporting the inner cylinder 10.

The inner cylinder 10 includes a shaft 12, and the outer cylinder 20 includes a rotation hole 22 that rotatably supports the shaft 12.

The rotation hole 22 is formed to extend in the extending direction of the outer cylinder 20. The rotation hole 22 may serve to guide the shaft 12 to move in the extension direction of the outer cylinder 20 while the shaft 12 is inserted into the rotation hole 22. Therefore, the inner cylinder 10 and the shaft 12 may linearly move in the extending direction of the rotation hole 22.

FIG. 10 is a side view of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 9.

The outer cylinder 20 has a top plate 23 extending outward from one side opening of the upper side. As shown in FIG. 9, when the inner cylinder 10 is accommodated in the outer cylinder 20 and is in a coupling position in which the inner cylinder 10 is coupled to the outer cylinder 20, the inner cylinder 10 may linearly move in an upward direction toward the top plate 23 of the outer cylinder 20 and a downward direction away from the top plate 23.

The rotation hole 22 of the outer cylinder 20 has an upper hole 22a that is adjacent to the top plate 23 of the outer cylinder 20 and accommodates the shaft 12, and a lower hole 22b that is connected to the upper hole 22a and extends downward from the upper hole 22a to accommodate the shaft 12. The rotation hole 22 also has a protruding jaw 22t for supporting the shaft 12 by protruding inwardly between the upper hole 22a and the lower hole 22b.

Referring to FIG. 9, the inner cylinder 10 has a pressing knob 13 formed concave on the outer surface thereof. The user may move the inner cylinder 10 with respect to the outer cylinder 20 by operating the pressing knob 13 with a finger while holding the outer cylinder 20 by hand.

Exemplary embodiments are not limited by the configuration of the pressing knob 13. For example, the pressing knob 13 may have a protrusion shape protruding from the outer wall surface of the inner cylinder 10.

As shown in FIGS. 9 and 10, when the inner cylinder 10 is in a coupling position in which the inner cylinder 10 is coupled to the outer cylinder 20, the shaft 12 may pass above the protruding jaw 22t and thus the inner cylinder 10 may move toward the top plate 23 of the outer cylinder 20 to move to a close contact position in which the inner cylinder 10 is in close contact with the outer cylinder 20. Alternatively, the shaft 12 may pass below the protruding jaw 22t and thus the inner cylinder 10 may move toward a lower side away from the top plate 23 of the outer cylinder 20 to move to a release position.

FIG. 10 shows a close contact position in which the inner cylinder 10 comes into close contact with the top plate 23 of the outer cylinder 20 and a cut-out hole 16 of the inner cylinder 10 contacts an extended support surface 26 of the outer cylinder 20.

FIG. 11 is a side view illustrating an operating state of the aerosol generating source support assembly according to the exemplary embodiment shown in FIGS. 9 and 10.

The inner cylinder 10 shown by the dashed line in FIG. 11 shows that the inner cylinder 10 has moved downward away from the top plate 23 of the outer cylinder 20 to a release position. Thus, the cut-out hole 16 of the inner cylinder 10 is spaced apart from the extended support surface 26 of the outer cylinder 20. As such, the inner cylinder 10 may rotate with respect to the outer cylinder 20 in the release position.

The inner cylinder 10 shown by the solid line in FIG. 11 shows the inner cylinder 10 that has moved to a separation position after rotating with respect to the outer cylinder 20. A portion of the inner cylinder 10 in the separation position may protrude to the outside of the outer cylinder 20 to maintain a posture for cleaning.

FIG. 12 is an enlarged side view of a portion of the aerosol generating source support assembly according to the exemplary embodiment of FIG. 11.

Referring to FIGS. 9 and 12, the inner cylinder 10 further includes an inner top plate 19 extending outward from an insertion opening of an upper end portion of the inner cylinder 10. When the inner cylinder 10 reaches the separation position shown in FIG. 12 by rotating with respect to the outer cylinder 20, an end portion of the edge of the inner top plate 19 comes into contact with the lower surface of the top plate 23 of the outer cylinder 20. That is, in the separation position in which the inner cylinder 10 has rotated with respect to the outer cylinder 20, the end portion of the edge of the inner top plate 19 of the inner cylinder 10 is strongly stuck to the lower surface of the top plate 23 of the outer cylinder 20, and thus, the position of the inner cylinder 10 with respect to the outer cylinder 20 may be fixed to the separation position.

As described above, since the inner cylinder 10 may rotate between the coupling position, in which the inner cylinder 10 is coupled to the outer cylinder 20, and the separation position, in which the inner cylinder 10 rotates with respect to the outer cylinder 20 to be separated from the outer cylinder 20, a cleaning operation may be easily performed. In particular, since the inner cylinder 10 is fixed in the separation position in which the inner cylinder 10 has been rotated with respect to the outer cylinder 20 as indicted by the solid line in FIG. 11, the user may easily clean the aerosol generating source support assembly.

FIG. 13 is a perspective view of an aerosol generating source support assembly according to another exemplary embodiment. FIG. 14A is a perspective view illustrating some components of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 13. FIG. 14B is a perspective view illustrating, at a different angle, some components of the aerosol generating source support assembly shown in FIG. 14A. FIG. 15A is a perspective view illustrating some other components of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 13.

The aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 13 includes an inner cylinder 10 which is hollow and has an empty interior, and an outer cylinder 20 having a rotation hole 22 connected to a shaft 12 of the inner cylinder 10 and rotatably supporting the inner cylinder 10 about an axis L.

The inner cylinder 10 includes an inner top plate 19 extending outward from an insertion opening 10a of an upper end portion of the inner cylinder 10, and a handle 19h protruding from the inner top plate 19 toward one side opening 20a of the outer cylinder 20.

Referring to FIG. 14B, the handle 19h has a groove grip 19f formed to be concave on the back of the handle 19h so that the user may grip with a nail. The groove grip 19f serves to prevent slippage when the user grips and operates the handle 19h. In addition, the inner top plate 19 has an entry portion 19g that provides a hole at a portion in contact with the groove grip 19f of the handle 19h. When the user's finger grips the handle 19h, the end of the finger may enter the entry portion 19g, and thus, the gripping operation of the groove grip 19f using the nail may be stably performed.

In FIG. 14B, the entry portion 19g is formed as a hole penetrated in the vertical direction, but exemplary embodiments are not limited by the configuration of the entry portion 19g. For example, the entry portion 19g may have the shape of a concave groove.

Referring to FIG. 13, the one side opening 20a of the outer cylinder 20 is enlarged outward from the center of the one side opening 20a to expose the handle 19h of the inner cylinder 10 to the outside.

When the inner cylinder 10 is in a coupling position in which the inner cylinder 10 is coupled to the outer cylinder 20 and accommodated in the outer cylinder 20, as shown in FIG. 13, the handle 19h on the upper side of the inner cylinder 10 is exposed to the outside. Therefore, the user may rotate the inner cylinder 10 with respect to the outer cylinder 20 by operating the handle 19h using a finger while holding the outer cylinder 20 by hand.

A concave portion 20w to facilitate the insertion of the user's finger is formed adjacent to the handle 19h, at the edge of the one side opening 20a of the outer cylinder 20.

Exemplary embodiment are not limited by the configuration of the handle 19h. For example, the handle 19h may have a concave shape on the inner top plate 19 of the inner cylinder 10.

Referring to FIG. 14A, the inner cylinder 10 includes a cut-out hole 16 to open a portion of a support space 15 to the outside for easy cleaning.

Referring to FIG. 15A, the outer cylinder 20 is hollow and has an accommodation space 25 to accommodate the inner cylinder 10 in the coupling position. The outer cylinder 20 includes one side opening 20a for opening one end of the accommodation space 25 to the outside, a lower side opening 26b for opening the other end of the accommodation space 25 to the outside, and an open passage 27 for opening the accommodation space 25 in the lateral direction.

In addition, the outer cylinder 20 has the extended support surface 26 protruding from the inner wall surface of the outer cylinder 20 so as to be coupled to the cut-out hole 16 of the inner cylinder 10 in the coupling position where the outer cylinder 20 is coupled to the inner cylinder 10.

When the outer cylinder 20 and the inner cylinder 10 is coupled to each other to be in the coupling position, the extended support surface 26 may be connected to the inner wall surface 11a of the inner cylinder 10, thereby extending in the circumferential direction in order to contact, surround, and support at least a portion of a cigarette. The extended support surface 26 of the outer cylinder 20 in the coupling position and the inner wall surface 11a of the inner cylinder 10 may form a circular shape corresponding to the cross-sectional shape of the cigarette.

The extended support surface 26 of the outer cylinder 20 has a protruding border 27f protruding and extending along the edge of the extended support surface 26. In addition, the cut-out hole 16 of the inner cylinder 10 has a groove 17g extending along the edge of the cut-out hole 16.

When the inner cylinder 10 rotates to the coupling position and is accommodated in the outer cylinder 20, the protruding border 27f of the outer cylinder 20 may be inserted into the groove 17g of the inner cylinder 10, and thus, the coupling position in which the inner cylinder 10 and the outer cylinder 20 are coupled to each other may be stably maintained.

Referring to FIG. 14A, the groove 17g has a straight portion 17l extending linearly in the extending direction of the inner cylinder 10, and a curved portion 17r connected to the straight portion 17I near a lower end portion of the inner cylinder 10 and extending in the circumferential direction of the inner cylinder 10. A connection portion 17d between the straight portion 17l and the curved portion 17r is formed to be curved.

Referring to FIG. 15A, the protruding border 27f of the outer cylinder 20 also includes a straight portion 271 extending in the extending direction of the outer cylinder 20, a curved portion 27r, and a connection portion 27d so as to correspond to the shape of the groove 17g of the inner cylinder 10.

When the inserting direction of a cigarette does not coincide with the center of the inner cylinder 10 when the cigarette is inserted into the inner cylinder 10 from the outside, and forms an inclined state, the cigarette may not be easily inserted in the inner cylinder 10.

According to the configuration of the aerosol generating source support assembly according to the exemplary embodiment described above, the connection portion 17d between the straight portion 17l and the curved portion 17r is formed to be curved, and thus, the connection portion 17d may smoothly guide an end portion of the cigarette inserted into the inner cylinder 10 in the inclined state. Therefore, the cigarette may be inserted in a correct posture into the inner cylinder 10 as the posture of the cigarette is modified by the connection portion 17d.

FIG. 14A includes an enlarged cross-sectional view illustrating a cross section of a portion of the straight portion 17l of the groove 17g. Referring to the cross-sectional view of FIG. 14A, the inner surface of the straight portion 17l includes curved areas 17m and 17n. The curved areas 17m and 17n may be formed over the entire area of the groove 17g that extends from the straight portion 17l to the connection portion 17d and the curved portion 17r.

When the cross-sectional shape of the corner of the groove 17g is a rectangular shape, debris generated in an aerosol generation process of the cigarette may accumulate in the corner. Thus, a cleaning operation may be difficult. However, in the aerosol generating source support assembly according to the exemplary embodiment described above, the cross section of the groove 17g of the cut-out hole 16 of the inner cylinder 10 includes the curved areas 17m and 17n, and thus, debris generated in the aerosol generation process of the cigarette may be easily removed from the groove 17g.

FIG. 15B is a side cross-sectional view of an aerosol generating source support assembly according to another exemplary embodiment.

The aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 15B includes an inner cylinder 10 and an outer cylinder 20 that supports the inner cylinder 10 such that the inner cylinder 10 may rotate between a coupling position and a separation position.

The inner cylinder 10 has a pressing knob 13 formed concave on the outer surface of the inner cylinder 10. In addition, the inner cylinder 10 has a handle 19j protruding upward through one side opening 20a of the outer cylinder 20 at an upper end portion of the inner cylinder 10. The handle 19j protrudes upward from the upper end of the one side opening 20a of the outer cylinder 20, and an end portion of the handle 19j has a shape bent outward.

According to the structure of the handle 19j, the area of the handle 19j that may be gripped by the user is large, and thus, the user may grip the handle 19j more easily and reliably. In addition, when the user moves the inner cylinder 10 with respect to the outer cylinder 20, the handle 19j and the pressing knob 13 of the inner cylinder 10 may be simultaneously gripped to apply force to the inner cylinder 10, and thus, an operation of changing the positions of the inner cylinder 10 and the outer cylinder 20 to the coupling position and a rotation position may be conveniently and stably performed.

When the inner cylinder 10 and the outer cylinder 20 are in the coupling position as shown in FIG. 15B, a cut-out hole 16 of the inner cylinder 10 and an extended support surface 26 of the outer cylinder 20 are coupled to each other, and thus, the outer cylinder 20 and the inner cylinder 10 form a space that may support the cigarette.

The inner cylinder 10 has a jaw 16s having a stepped shape at a lower portion of the cut-out hole 16 coupled with the extended support surface 26 of the outer cylinder 20. The jaw 16s having a stepped shape forms a height S from the bottom surface of the inner cylinder 10.

Therefore, when the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 15B is coupled to the protrusion tube 1020, the movement of a substance generated in an inner space formed by the inner cylinder 10 and the outer cylinder 20 to surround the cigarette is blocked by the jaw 16s having a stepped shape. That is, a substance in the inner space formed by the inner cylinder 10 and the outer cylinder 20 may be effectively blocked by the jaw 16s having a stepped shape so as not to leak toward the coupling passage 1020h of the protrusion tube 1020.

In FIG. 15B, the jaw 16s is shown as a stepped shape with two steps, but the exemplary embodiment is not limited by the specific shape of the jaw 16s and the jaw 16s may have a stepped shape with three or more steps.

FIG. 16 is a perspective view of an aerosol generating source support assembly according to another exemplary embodiment. FIG. 17 is a perspective view illustrating an operating state of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 16. FIG. 18 is a perspective view of the back of the aerosol generating source support assembly according to the exemplary embodiment shown in FIG. 17.

The aerosol generating source support assembly 104 according to the exemplary embodiment shown in FIGS. 16 to 18 has an inner cylinder 110, which is hollow and may surround and support at least a portion of an aerosol generating source, and an outer cylinder 120 for movably supporting the inner cylinder 110 such that the inner cylinder 110 may move between a coupling position and a separation position.

In the aerosol generating source support assembly 104 according to the exemplary embodiment shown in FIGS. 16 to 18, the inner cylinder 110 is modified to move linearly with respect to the outer cylinder 120. The inner cylinder 110 is coupled to the outer cylinder 120 to move linearly with respect to the outer cylinder 120 in a direction in which the outer cylinder 120 extends.

Referring to FIG. 18, the outer cylinder 120 is hollow and has an accommodation space 25 having an empty interior. The outer cylinder 120 is manufactured in a substantially semi-cylindrical shape so as to surround and support at least another portion of the aerosol generating source, i.e. a cigarette. The outer cylinder 120 has an outer cylinder cut-out hole 127 for exposing at least a portion of the accommodation space 25 to the outside.

Referring to FIG. 17, the inner cylinder 110 is hollow and has a support space 15. The inner cylinder 110 is manufactured in a substantially semi-cylindrical shape so as to surround and support at least a portion of a cigarette which is an aerosol generating source. The inner cylinder 110 exposes the support space 15 to the outside and has an inner cylinder cut-out hole 117 with a shape corresponding to the outer cylinder cut-out hole 127 of the outer cylinder 120.

The exemplary embodiment is not limited by the configurations of the inner cylinder 110 and the outer cylinder 120 shown as having semi-cylindrical shapes. For example, one of the inner cylinder 110 and the outer cylinder 120 may have an acute arc-shaped cross section, and the other of the inner cylinder 110 and the outer cylinder 120 may have an obtuse arc-shaped cross section corresponding to the acute arc-shaped cross section.

The outer cylinder 120 has an insertion opening 120a that allows the aerosol generating source to be inserted, at one end portion of the outer cylinder 120.

The inner cylinder 110 may include a heater insertion opening 10b provided at an opposite end portion of the inner cylinder 110 which is opposite to the insertion opening 120a of the outer cylinder 120.

The position of the inner cylinder 110 may be changed to a coupling position in which the inner cylinder 110 and the outer cylinder 120 are coupled to each other, as shown in FIG. 16, or may be changed to a separation position in which at least a portion of the inner cylinder 110 is separated from the outer cylinder 120, as shown in FIGS. 17 and 18.

When the inner cylinder 110 and the outer cylinder 120 are in the coupling position shown in FIG. 16, both the outer cylinder cut-out hole 127 and the inner cylinder cut-out hole 117 are closed, and thus, the inner cylinder 110 and the outer cylinder 120 may form an aerosol generating source insertion space to accommodate an aerosol generating source therein.

Since the outer cylinder cut-out hole 127 and the inner cylinder cut-out hole 117 are exposed to the outside when the inner cylinder 110 and the outer cylinder 120 are in the separation position shown in FIGS. 17 and 18, a cleaning operation may be conveniently performed.

Referring to FIGS. 17 and 18, rails 127a, 1101 for guiding the linear movement of the inner cylinder 110 are installed in an area between the outer cylinder 120 and the inner cylinder 110, in which the outer cylinder cut-out hole 127 and the inner cylinder cut-out hole 117 are engaged with each other. The rail 127a, 1101 may include a straight protruding portion 127a and a straight groove 1101 to accommodate the straight protruding portion, which extend in a direction in which the outer cylinder 120 and the inner cylinder 110 extend. The straight protruding portion 127a may be installed in either the outer cylinder 120 or the inner cylinder 110, and the straight groove 1101 may be installed in the other.

Each of the outer cylinder cut-out hole 127, the inner cylinder cut-out hole 117, and the rails 127a, 1101 includes curved areas 127r, 110r. The curved areas 127r, 110r may be formed over the entire area where the rails 127a, 1101 extend.

When the cross-sectional shapes of the corners of the rails 127a and 1101 are rectangular shapes, debris generated in an aerosol generation process of the cigarette may accumulate in the corners and thus, a cleaning operation may be difficult. However, in the aerosol generating source support assembly according to the exemplary embodiment described above, each of the rails 127a, 1101 includes the curved areas 127r, 110r, and thus, debris generated during the aerosol generation process of the cigarette may be easily removed.

A fixing device for fixing the positions of the outer cylinder 120 and the inner cylinder 110 is installed between the outer cylinder 120 and the inner cylinder 110. The fixing device includes a first stopper 120s and a second stopper 120t arranged to protrude on an outer surface of the outer cylinder 120, and an accommodation groove 110s installed in the inner cylinder 110 to support the first stopper 120s and the second stopper 120t.

The first stopper 120s and the second stopper 120t have a substantially hemispherical shape having a substantially arc-shaped cross-sectional shape. Therefore, the outer surface of each of the first stopper 120s and the second stopper 120t is curved. Due to the structures of the first stopper 120s and the second stopper 120t, an operation in which the first stopper 120s and the second stopper 120t enter the accommodation groove 110s may be smoothly performed.

The inner cylinder 110 has a grip handle 110y having a concave groove shape and extending in the circumferential direction so that a user may grip and operate it by hand. The user may easily and conveniently change the positions of the inner cylinder 110 and the outer cylinder 120 in a state of gripping the grip handle 110y. The exemplary embodiment is not limited by the shape of the grip handle 110y. For example, the grip handle 110y may have a shape protruding outward from the inner cylinder 110.

In the coupling position of FIG. 16, the accommodation groove 110s accommodates the first stopper 120s, thereby stably maintaining a state in which the outer cylinder 120 and the inner cylinder 110 are coupled to each other.

In the separation position shown in FIGS. 17 and 18, the accommodation groove 110s accommodates the second stopper 120t, thereby stably maintaining a state in which the outer cylinder 120 and the inner cylinder 110 are separated from each other.
