Aerosol generator

[0001] The present disclosure relates to an aerosol generating device.

[0002] An aerosol generator is designed to extract a specific component from a medium or substance through an aerosol. The medium may contain various components. The components contained in the medium may include various flavoring substances. For example, the components contained in the medium may include nicotine, herbal ingredients, and / or coffee ingredients. Recently, extensive research has been conducted on such aerosol generators.

[0003] In an aerosol generating device including a cartridge, an aerosol generating substance inside the cartridge is absorbed by an absorbent member. The aerosol generating substance may be heated by a heater to generate an aerosol.

[0004] In conventional aerosol generators, users may remove the absorbent material and reuse the cartridge by injecting an aerosol generating substance into the cartridge. In this case, the user may use a different aerosol generating substance than the one included with the aerosol generator upon shipment, and the cartridge may be damaged during the aerosol generating substance injection process, resulting in malfunction or failure of the aerosol generator.

[0005] The present disclosure aims to solve the above-mentioned and other problems.

[0006] Another object may be to provide an aerosol generating device having an absorbent member at least partially exposed to the outside of the cartridge and a catch member protruding into the inside of the cartridge and inserted into the absorbent member to engage with the absorbent member.

[0007] Another object may be to provide an aerosol generating device having a stud protruding sharply into the cartridge and having a shape that gradually increases in height in the direction in which the leg protrudes from the absorbent member, and is inserted into one side of the leg.

[0008] Another object may be to provide an aerosol generating device having a body hole that exposes an absorbent member to the outside and has a hook portion that protrudes in a direction intersecting with the direction in which the body hole is opened and is inserted into the absorbent member to be coupled with the absorbent member.

[0095] The leg (552) may include a first leg (552a) and a second leg (552b). The first leg (552a) and the second leg (552b) may be spaced apart from each other. The first leg (552a) and the second leg (552b) may be formed in a shape that is symmetrical to each other. The first leg (552a) and the second leg (552b) may protrude in opposite directions from the absorbent body (551). For example, the first leg (552a) may protrude in a first direction (e.g., in the opposite direction of the x direction) that intersects the direction in which the absorbent body (551) extends from the absorbent body (551). The second leg (552b) may protrude in a second direction (e.g., x direction) that intersects the direction in which the absorbent body (551) extends from the absorbent body (551) and is opposite to the first direction. The absorbent member (550) may have an overall 'T' shape when viewed from one side.

[0096] The absorbent member (550) may be fixed within the cartridge body (510). The absorbent member (550) may be placed in an absorbent member receiving portion (514) extending inwardly from the body hole (513). The absorbent member receiving portion may be referred to as an absorbent chamber. The absorbent member receiving portion (514) may be in contact with a side surface of the absorbent body (551) and may surround or support the side surface. The absorbent member receiving portion (514) may be in contact with an upper surface of the absorbent member (550) and may support the upper surface. The absorbent member receiving portion (514) may be in communication with a storage chamber (527). One lower side of the storage chamber (527) may be open and may be in communication with the absorbent member receiving portion (514). The first leg (552a) and the second leg (552b) may be respectively positioned on opposite sides of the upper portion of the absorbent member receiving portion (514). One end of the leg (552) may be exposed to the storage chamber (527). One end of the first leg (552a) may be exposed to the storage chamber (527) through the left end of the upper portion of the absorbent member receiving portion (514). One end of the second leg (552b) may be exposed to the storage chamber (527) through the right end of the upper portion of the absorbent member receiving portion (514).

[0097]

[0098] Referring to FIG. 8 together with FIG. 7, the first catch (580) may protrude from the cartridge body (510) into the cartridge body (510). For example, the first catch (580) may protrude from the lower cover (512) of the cartridge body (510) into the interior or upper side of the cartridge body (510).

[0099] The first catch (580) may be provided in the absorption chamber receiving portion (514). The lower cover (512) may form the absorption chamber receiving portion (514). The lower cover (512) may form one side of the upper side of the absorption chamber receiving portion (514). The first catch (580) may include at least one catch protrusion (581, 582) protruding upward (e.g., in the z direction) from the lower cover (512).

[0100] The catches (581, 582) may include a first catch (581) and a second catch (582). The first catch (581) may be arranged at the upper left portion of the absorption chamber receiving portion (514). The second catch (582) may be arranged at the upper right portion of the absorption chamber receiving portion (514). The first catch (581) may be inserted into the first leg (552a) accommodated in the absorption chamber receiving portion (514). The second catch (582) may be inserted into the second leg (552b) accommodated in the absorption chamber receiving portion (514).

[0101] The hooks (581, 582) may be pointedly protruded in a direction intersecting with the direction in which the legs (552) protrude. The first hook (581) may be pointedly protruded in a direction intersecting with the direction in which the first leg (552a) protrudes. The second hook (582) may be pointedly protruded in a direction intersecting with the direction in which the second leg (552b) protrudes.

[0102] The stumbling blocks (581, 582) may have a polygonal pyramidal shape. For example, the stumbling blocks (581, 582) may have a triangular pyramidal shape. The stumbling blocks (581, 582) may include a first surface (5801), a second surface (5802), and a third surface (5803) forming respective surfaces of the protruding triangular pyramids. The first surface (5801) and the third surface (5803) may be connected to each other by forming one corner and may be arranged in a direction toward the inside of the absorption chamber receiving portion (514) or the absorption body (551). The first surface (5801) and the third surface (5803) may be referred to as inclined surfaces. The second surface (5802) is connected to each of the first surface (5801) and the third surface (5803) by forming an edge, and may be arranged in the direction in which the inside of the storage chamber (527) or the leg (552) protrudes. The second surface (5802) may be referred to as a hook surface. The upper end or vertex of the hooking projection (581, 582) formed by the first surface to the third surface may face a direction intersecting with the direction in which the leg (552) protrudes. The sharply protruding hooking projection (581, 582) may be inserted into the leg (552) and coupled or engaged with the leg (552).

[0103] However, the shape of the stumbling block (581, 582) is not limited thereto, and may have a semi-conical shape. That is, other shapes are also possible as long as the protruding end of the stumbling block is pointed and one surface is formed facing the direction in which the leg protrudes.

[0104] Meanwhile, if the catch (581, 582) has a rib or ring-shaped structure that protrudes upward and extends in the circumferential direction of the leg (552), the catch (581, 582) may not be inserted into the leg (552). In this case, the catch (581, 582) may not be able to fix the leg (552) or restrict the one-way movement of the leg (552).

[0105]

[0106] Referring to FIG. 9 together with FIGS. 7 and 8, the stumbling blocks (581, 582) may gradually increase in height in the direction in which the legs (552) protrude. For example, the first stumbling block (581) may gradually increase in protrusion height in the direction in which the first leg (552a) protrudes. The second stumbling block (582) may gradually increase in protrusion height in the direction in which the second leg (552b) protrudes. For example, the first stumbling block (581) and the second stumbling block (582) may gradually increase in protrusion height in opposite directions.

[0107] The first surface (5801) and / or the third surface (5803) of the catch (581, 582) can form a certain angle (a1, a3) with respect to the direction in which the leg (552) protrudes. For example, the first surface (5801) and / or the third surface (5803) of the first catch (581) can form a first angle (a1) with respect to the direction in which the first leg (552a) protrudes. For example, the first surface (5801) and / or the third surface (5803) of the second catch (582) can form a third angle (a3) ​​with respect to the direction in which the second leg (552b) protrudes.

[0108] The second surface (5802) of the stumbling block (581, 582) can form a certain angle (a2, a4) with respect to the opposite direction of the protrusion of the leg (552). For example, the second surface (5802) of the first stumbling block (581) can form a second angle (a2) with respect to the opposite direction of the protrusion of the first leg (552a). For example, the second surface (5802) of the second stumbling block (582) can form a fourth angle (a4) with respect to the protrusion of the second leg (552b).

[0109] The second angle (a2) may be greater than the first angle (a1). For example, the first angle (a1) may be an acute angle, and the second angle (a2) may be an acute angle greater than the first angle (a1). For example, the first angle (a1) may be an acute angle, and the second angle (a2) may be a right angle or an obtuse angle.

[0110] The fourth angle (a4) may be greater than the third angle (a3). For example, the third angle (a3) ​​may be an acute angle, and the fourth angle (a4) may be an acute angle greater than the third angle (a3). For example, the third angle (a3) ​​may be an acute angle, and the fourth angle (a4) may be a right angle or an obtuse angle.

[0111]

[0112] Referring to FIG. 10 together with FIG. 9, when the first catch (581) is inserted into the first leg (552a), and the first leg (552a) moves in the protruding direction of the first leg (552a) (e.g., in the opposite direction to the x direction), the first leg (552a) can slide along the first surface (5801) and / or the third surface (5803). When the first catch (581) is inserted into the first leg (552a), and the first leg (552a) moves in the opposite direction to the protruding direction of the first leg (552a) (e.g., in the x direction), the movement can be prevented by the second surface (5802). Alternatively, at least a portion of the first leg (552a) can be damaged by the second surface (5802).

[0113] When the second catch (582) is inserted into the second leg (552b), and the second leg (552b) moves in the protruding direction of the second leg (552b) (e.g., in the x direction), the second leg (552b) can slide along the first surface (5801) and / or the third surface (5803). When the second catch (582) is inserted into the second leg (552b), and the second leg (552b) moves in the opposite direction to the protruding direction of the second leg (552b) (e.g., in the opposite direction to the x direction), the movement can be prevented by the second surface (5802). Alternatively, at least a portion of the second leg (552b) can be damaged by the second surface (5802).

[0114] When the exposed portion of the absorbent member (550) is pulled out of the cartridge (500) by an external force, a part of the absorbent body (551) can be extracted out of the cartridge (500) through the body hole (513). In this case, the leg (552) connected to the absorbent body (551) can move in the opposite direction to the direction in which the leg (552) protrudes. The movement of the first leg (552a) and the second leg (552b) can be prevented by the first catch (581) and the second catch (582), respectively. Alternatively, at least a part of the first leg (552a) and the second leg (552b) may be damaged by the first catch (581) and the second catch (582).

[0115] That is, the absorbent member (550) may be damaged by the stumbling block (581, 582), thereby preventing reuse of the cartridge (500).

[0116] Meanwhile, although not shown in the drawing, the first catch (581) and the second catch (582) may each include a plurality of catches. For example, the first catch (581) may include a plurality of catches that protrude upward from the lower cover (512) and are spaced apart from each other, and the second catch (582) may include a plurality of catches that protrude upward from the lower cover (512) and are spaced apart from each other. For example, the first catch (581) may include a plurality of catches that are spaced apart from each other along the periphery of the first leg (552a), and the second catch (582) may include a plurality of catches that are spaced apart from each other along the periphery of the second leg (552b).

[0117] Accordingly, the absorbent member (550) can be firmly fixed within the cartridge (500) by a plurality of stumbling blocks, and the absorbent member (550) can be prevented from being extracted outside the cartridge.

[0118]

[0119] Fig. 11 is a cross-sectional view of an aerosol generating device according to an embodiment of the present disclosure, Fig. 12 is a perspective cross-sectional view showing an absorbent member of an aerosol generating device according to an embodiment of the present disclosure in a state where the absorbent member is not coupled, and Fig. 13 is a cross-sectional view illustrating damage to an absorbent member when inserted in an aerosol generating device according to an embodiment of the present disclosure. Figs. 11 to 13 each show a cross-section of a cartridge (500) along line AA of Fig. 4.

[0120] Among the matters related to FIGS. 11 to 13, detailed descriptions of features that overlap with the features of FIGS. 6 to 10 will be omitted.

[0121] Referring to Fig. 11, a second catch (590) may be provided on the cartridge body (510). The second catch (590) may protrude into the cartridge body (510). The second catch (590) may be positioned adjacent to the body hole (513). The second catch (590) may protrude in a direction (e.g., the x direction, the y direction, or the opposite direction) intersecting with the direction in which the body hole (513) is opened (e.g., the opposite direction to the z direction). The second catch (590) may be formed integrally with the cartridge body (510).

[0122] The second catch (590) can be inserted into one side of the absorbent member (550) placed within the cartridge body (510). The second catch (590) can be inserted into the absorbent member (550) and combined or engaged with the absorbent member (550).

[0123]

[0124] Referring to Fig. 12, the second catch (590) may protrude from the cartridge body (510) into the cartridge body (510). The second catch (590) may be provided in the absorption chamber receiving portion (514). The lower cover (512) may form the absorption chamber receiving portion (514). The second catch (590) may include at least one catch protrusion (591, 592) protruding from the side of the absorption chamber receiving portion (514) into the absorption chamber receiving portion (514).

[0125] The catches (591, 592) may include a third catche (591) and a fourth catche (592). The third catche (591) may be arranged on the left side of the absorption chamber receiving portion (514). The fourth catche (592) may be arranged on the right side of the absorption chamber receiving portion (514). The third catche (591) and the fourth catche (592) may be arranged to face each other within the absorption chamber receiving portion (514). The third catche (591) may be inserted into one side of the absorption body (551) received in the absorption chamber receiving portion (514). The fourth catche (592) may be inserted into the other side of the absorption body (551) received in the absorption chamber receiving portion (514).

[0126] The stumbling block (591, 592) may be sharply protruded in a direction intersecting with the direction in which the absorption body (551) extends or in a direction intersecting with the direction in which the body hole (513) is opened.

[0127] For example, the studs (591, 592) may have a triangular pyramid shape. The studs (591, 592) may include a first surface (5901), a second surface (5902), and a third surface (5903) which form each surface of the protruding triangular pyramid. The first surface (5901) and the third surface (5903) may be connected to each other by forming a corner, and may be arranged in an opposite direction (e.g., z direction) to the direction in which the body hole (513) is opened. The first surface (5901) and the third surface (5903) may be referred to as inclined surfaces. The second surface (5902) may be connected to each of the first surface (5901) and the third surface (5903) by forming a corner, and may be arranged in the direction in which the body hole (513) is opened. The second surface (5902) may be referred to as a hook surface. The upper ends or vertices of the hook projections (591, 592) formed by the first to third surfaces may face in a direction intersecting with the direction in which the body hole (513) is opened. The sharply protruding hook projections (591, 592) may be inserted into the absorbent body (551) and coupled or engaged with the absorbent body (551).

[0128] The stumbling blocks (591, 592) can gradually increase in height in the direction in which the body hole (513) is opened. The third stumbling block (591) and the fourth stumbling block (592) can gradually increase in protruding height in the same direction. The shape of the stumbling blocks (591, 592) of the second stumbling portion (590) can correspond to the shape of the stumbling blocks (581, 582) of the first stumbling portion (580), except for the direction in which the protruding height increases.

[0129]

[0130] Referring to FIG. 13, when the absorbent member (550) is moved inwardly (e.g., in the z direction) through the body hole (513) in a state in which it is extracted from the cartridge (500), the movement may be impeded by the second surface (5902) of the catch (591, 592). Alternatively, at least a portion of the absorbent body (551) and / or the leg (552) may be damaged by the second surface (5902).

[0131] That is, the re-insertion of the absorbent member (550) may be prevented by the stumbling block (591, 592) or the absorbent member (550) may be damaged, thereby preventing the reuse of the cartridge (500).

[0132] Meanwhile, the catch may further include a fifth catch (593) and a sixth catch (not shown). The fifth catch (593) may be arranged between the third catch (591) and the fourth catch (592) in the circumferential direction of the absorption chamber receiving portion (514). The fifth catch may be arranged between the third catch (591) and the fourth catch (592) in the circumferential direction of the absorption chamber receiving portion (514) and may be arranged to face the fifth catch (593). That is, the third to sixth catches may be arranged to be spaced apart from each other along the circumference of the absorption member (550).

[0133] Accordingly, the absorbent member (550) can be firmly fixed within the cartridge (500) by a plurality of stumbling blocks, and the extracted absorbent member (550) can be prevented from being reinserted from the outside to the inside of the cartridge (500).

[0134] Meanwhile, the fifth catch (593) and the sixth catch may be arranged in opposite directions to the third catch (591) and the fourth catch (592). For example, the third catch (591) and the fourth catch (592) may gradually increase in height in the direction in which the body hole (513) is opened, and the fifth catch (593) and the sixth catch may gradually increase in height in the direction opposite to the direction in which the body hole (513) is opened.

[0135] Accordingly, the absorbent member (550) can be prevented from being extracted outside the cartridge (500) by the fifth and sixth catches (591), and the absorbent member (550) can be prevented from being reinserted from the outside to the inside of the cartridge (500) by the third and fourth catches (591) and the fourth catches (592).

[0136]

[0137] Meanwhile, the first catch (580) illustrated in FIGS. 6 to 10 and the second catch (590) illustrated in FIGS. 11 to 13 may be provided together in one cartridge (500). Accordingly, the first catch (580) may prevent the absorbent member (550) from being extracted outside the cartridge (500), and the second catch (590) may prevent the absorbent member (550) from being reinserted from the outside to the inside of the cartridge (500).

[0138]

[0139] Figures 14 and 15 are cross-sectional views of an aerosol generating device according to another embodiment of the present disclosure. Figures 14 and 15 each show a cross-section of a cartridge (500) along line AA of Figure 4.

[0140] Among the matters related to FIGS. 14 and 15, detailed descriptions of features that overlap with the features of FIGS. 6 to 13 will be omitted.

[0141] Referring to FIG. 14, the absorbent member (550) may include an absorbent body (551) and a leg (552). The leg (552) may protrude from the absorbent body (551) to one side. For example, the leg (552) may protrude from the absorbent body (551) in a direction (e.g., z direction) intersecting with the direction in which the absorbent body (551) extends. The leg (552) may include a first leg (552a) and a second leg (552b). The first leg (552a) and the second leg (552b) may be spaced apart from each other. The first leg (552a) and the second leg (552b) may be formed in a shape that is symmetrical to each other. The first leg (552a) and the second leg (552b) may protrude in the same direction from the absorbent body (551). The absorbent member (550) may have an overall 'U' shape when viewed from one side.

[0142] The first catch (580) may protrude from the cartridge body (510). For example, the first catch (580) may include at least one catch protrusion (581, 582) protruding from the inner surface of the absorbent member receiving portion (514) toward the storage chamber (527).

[0143] The hooks (581, 582) may be pointedly protruded in a direction intersecting with the direction in which the legs (552) protrude. The first hook (581) may be pointedly protruded in a direction intersecting with the direction in which the first leg (552a) protrudes. The second hook (582) may be pointedly protruded in a direction intersecting with the direction in which the second leg (552b) protrudes.

[0144] The first catch (581) may protrude in a direction toward the inner surface of the first leg (552a) (e.g., in the opposite direction of the x direction). The second catch (582) may protrude in a direction toward the inner surface of the second leg (552b) (e.g., in the x direction). The first catch (581) and the second catch (582) may protrude in opposite directions.

[0145] The stumbling blocks (581, 582) may gradually increase in height in the direction in which the legs (552) protrude. For example, the first stumbling block (581) may gradually increase in height in the direction in which the first leg (552a) protrudes. The second stumbling block (582) may gradually increase in height in the direction in which the second leg (552b) protrudes. For example, the first stumbling block (581) and the second stumbling block (582) may gradually increase in height in the same direction. The sharply protruding stumbling blocks (581, 582) may be inserted into the legs (552) and coupled or engaged with the legs (552).

[0146] When the studs (581, 582) are inserted into the legs (552), and the legs (552) move in a direction opposite to the protrusion direction of the legs (552) (e.g., in the opposite direction of the z direction), the movement of the legs (552) may be impeded by the studs (581, 582). Alternatively, at least a portion of the legs (552) may be damaged by the studs (581, 582).

[0147] If the exposed portion of the absorbent member (550) is pulled out of the cartridge (500) by an external force, the movement of the leg (552) may be impeded by the catches (581, 582). Alternatively, at least a portion of the leg (552) may be damaged by the catches (581, 582).

[0148] That is, the absorbent member (550) may be damaged by the stumbling block (581, 582), thereby preventing reuse of the cartridge (500).

[0149]

[0150] Referring to Fig. 15, the second catch (590) may protrude from the cartridge body (510). The second catch (590) may be positioned adjacent to the body hole (513). For example, the second catch (590) may include at least one catch protrusion (591, 592) protruding from the outer surface of the absorbent member receiving portion (514) toward the inside of the absorbent member receiving portion (514).

[0151] The third catch (591) may be arranged on the left side of the absorption chamber receiving portion (514). The fourth catch (592) may be arranged on the right side of the absorption chamber receiving portion (514). The third catch (591) and the fourth catch (592) may be arranged to face each other within the absorption chamber receiving portion (514). The third catch (591) may be inserted into one side of the absorption body (551) received in the absorption chamber receiving portion (514). The fourth catch (592) may be inserted into the other side of the absorption body (551) received in the absorption chamber receiving portion (514).

[0152] The stumbling block (591, 592) may be sharply protruded in a direction intersecting with the direction in which the body hole (513) is opened.

[0153] The stumbling blocks (591, 592) can gradually increase in height in the direction in which the body hole (513) is opened. The third stumbling block (591) and the fourth stumbling block (592) can gradually increase in protruding height in the same direction. The shape of the stumbling blocks (591, 592) of the second stumbling portion (590) can correspond to the shape of the stumbling blocks (581, 582) of the first stumbling portion (580), except for the direction in which the protruding height increases.

[0154] When the absorbent member (550) is moved inwardly (e.g., in the z direction) of the cartridge (500) through the body hole (513) while being extracted from the cartridge (500), the movement may be impeded by the catches (591, 592). Alternatively, at least a portion of the absorbent body (551) and / or the leg (552) may be damaged by the catches (591, 592).

[0155] That is, the re-insertion of the absorbent member (550) may be prevented by the stumbling block (591, 592) or the absorbent member (550) may be damaged, thereby preventing the reuse of the cartridge (500).

[0156]

[0157] Meanwhile, the first catch (580) illustrated in FIG. 14 and the second catch (590) illustrated in FIG. 15 may be provided together in one cartridge (500). Accordingly, the first catch (580) may prevent the absorbent member (550) from being extracted outside the cartridge (500), and the second catch (590) may prevent the absorbent member (550) from being reinserted from the outside to the inside of the cartridge (500).

[0158]

[0159] Fig. 16 is a block diagram of an aerosol generating device (1) according to one embodiment of the present disclosure.

[0160] The aerosol generator (1) may include a power source (11), a control unit (12), a sensor (13), an output unit (14), an input unit (15), a communication unit (16), a memory (17), and at least one heater (18, 24). However, the internal structure of the aerosol generator (1) is not limited to that illustrated in Fig. 16. That is, a person having ordinary skill in the art related to the present embodiment will understand that some of the components illustrated in Fig. 16 may be omitted or new components may be added depending on the design of the aerosol generator (1).

[0161] The sensor (13) can detect the status of the aerosol generator (1) or the status around the aerosol generator (1) and transmit the detected information to the control unit (12). Based on the detected information, the control unit (12) can control the aerosol generator (1) so that various functions such as controlling the operation of the cartridge heater (24) and / or heater (18), restricting smoking, determining whether a stick (S) and / or cartridge (19) is inserted, and displaying a notification are performed.

[0162] The sensor (13) may include at least one of a temperature sensor (131), a puff sensor (132), an insertion detection sensor (133), a reuse detection sensor (134), a cartridge detection sensor (135), a cap detection sensor (136), and a movement detection sensor (137).

[0203] The control unit (12) can control the on / off operation of the switching element included in the power conversion circuit to adjust the level of the voltage output from the power conversion circuit. When the on state of the switching element continues, the level of the voltage output from the power conversion circuit may correspond to the level of the voltage output from the power source (11). The duty ratio for the on / off operation of the switching element may correspond to the ratio of the voltage output from the power conversion circuit to the voltage output from the power source (11). As the duty ratio for the on / off operation of the switching element decreases, the level of the voltage output from the power conversion circuit may decrease.
