[0014] In one embodiment, the movable member may include a pressure surface provided on one side facing the pressure member and having a structure that is temporarily deformable when pressed by the pressure member.

[0015] In one embodiment, the movable member may be formed of a single continuous conductive material.

[0016] In one embodiment, the movable member may be formed of a structure coated with a conductive material.

[0017] In one embodiment, the first conductive member and the second conductive member may have a shape extending along the movement direction of the moving member.

[0018] In one embodiment, the first conductive member and the second conductive member may have substantially the same shape.

[0019] In one embodiment, the first housing may include: an accommodation space in which the switch is accommodated; and an insertion hole communicating from the accommodation space to the outside of the first housing, into which the pressing member is inserted when the first housing and the second housing are coupled; and a sealing film that opens the insertion hole when the pressing member is inserted and seals the insertion hole when the pressing member is withdrawn.

[0020] In one embodiment, the movable member may include a body made of a non-conductive material and a conductive region coupled to the body.

[0021] In one embodiment, the conductive region can simultaneously contact the first conductive member and the second conductive member when the movable member is moved by the pressing member.

[0056] In one embodiment, an airflow channel (23) may be provided in the cartridge (19). The airflow channel (23) may communicate with the outside of the cartridge and an atomizing space in which a heater (24) or a liquid delivery means (25) is disposed. One end of the airflow channel (23) may be opened to the atomizing space in which the heater (24) or the liquid delivery means (25) is disposed, and the other end of the airflow channel (23) may be communicated with a mouthpiece (35).

[0057] For example, referring to FIG. 1, the airflow channel (23) may extend along the length of the cartridge (19) from one side of the chamber (20) of the cartridge (19). Or, for example, referring to FIG. 2, the airflow channel (23) may extend along the length of the cartridge (19) by penetrating the chamber (20) of the cartridge (19).

[0058] In one embodiment, the battery (11) can supply power to operate components of the aerosol generating device. The battery (11) can be a power source or power source. The battery (11) can supply power to at least one of the control unit (12), the sensor (13), and the heater (24).

[0059] In one embodiment, the control unit (12) can control the overall operation of the aerosol generating device (1). For example, the control unit (12) can control the operation of at least one of the battery (11), the sensor (13), and the cartridge (19).

[0063] In one embodiment, the control unit (12) can analyze the results detected by the sensor (13) and control the processes to be performed thereafter. For example, the control unit (12) can control the power supplied to the heater (24) so ​​that the operation of the heater (24) is initiated or terminated based on the results detected by the sensor (13).

[0064] For example, the control unit (12) can control the amount of power supplied to the heater (24) and the time for which the power is supplied so that the heater (24) can be heated to a predetermined temperature or maintained at an appropriate temperature based on the result detected by the sensor (13).

[0073] In one embodiment, the first housing (111) can accommodate at least one of a battery (105) (e.g., battery (11) of FIG. 1 or 2), a control unit (107) (e.g., control unit (12) of FIG. 1 or 2), a heater (120) (e.g., heater (24) of FIG. 1 or 2), and a wick (121) (e.g., liquid delivery means (25) of FIG. 1 or 2).

[0074] In one embodiment, the battery (105) can supply power necessary for the operation of the components of the aerosol generating device (100). The control unit (107) can control the operation of at least one of the components of the aerosol generating device (100).

[0075] In one embodiment, the heater (120) may be placed in the first housing (111). An atomizing space (115) may be provided inside the first housing (111). The heater (120) may be placed in the atomizing space (115). The heater (120) may heat the wick (121). The heater (120) may be attached to the wick (121).

[0076] In one embodiment, the wick (121) may be placed in the atomizing space (115). The upper end of the wick (121) may have a shape that protrudes from the atomizing space (115) toward the upper side of the first housing (111).

[0079] In one embodiment, the first housing (111) may have a first aerosol channel (119) that communicates with the atomizing space (115). The first aerosol channel (119) may communicate from the atomizing space (115) to the outside of the first housing (111). The first aerosol channel (119) may transfer aerosol generated in the atomizing space (115) to the outside of the first housing (111). For example, the first aerosol channel (119) may be connected to a second aerosol channel (129) of the second housing (112) to transfer aerosol to the second housing (112).

[0080] In one embodiment, the second housing (112) may include at least one of a chamber (127) (e.g., chamber (20) of FIG. 1 or 2) and an airflow channel (131) (e.g., airflow channel (23) of FIG. 1 or 2). The second housing (112) may store an aerosol generating material in the chamber (127). The chamber (127) may be a storage tank.

[0081] In one embodiment, the mouthpiece (130) may be positioned on the upper side (e.g., in the +Z direction) of the second housing (112). Alternatively, the mouthpiece (130) may cover the upper portion of the second housing (112). The mouthpiece (130) may include an intake port (135) that communicates with the exterior of the second housing (112).

[0082] In one embodiment, the airflow channel (131) may be in communication with the second aerosol path (129) and the intake port (135).

[0085] In one embodiment, the wick (121) can receive and absorb an aerosol generating substance from the second housing (112). The heater (120) can heat the wick (121) that has absorbed the aerosol generating substance to generate an aerosol in the atomizing space (115).

[0086] In one embodiment, when the second housing (112) is coupled to the first housing (111), the second aerosol passage (129) and the first aerosol passage (119) can be connected. A user can hold the mouthpiece (130) in their mouth and inhale air from the inlet (135). The aerosol formed in the atomizing space (115) can pass through the first aerosol passage (119), the second aerosol passage (129), and the airflow channel (131) to be delivered to the inlet (135).

[0087] In one embodiment, the first housing (111) and the second housing (112) can be replaced independently of each other.

The user can replace only the second housing (112) separately or only the first housing (111) separately.

[0088] For example, the consumption cycle of the aerosol generating material stored in the second housing (112) may be shorter than the appropriate replacement cycle of the first housing (111). When the second housing (112) is replaced multiple times, the first housing (111) may be replaced only once. The user can use the first housing (111) for a longer period of time, and the replacement cost of some components may be reduced.

[0089] In one embodiment, the first sealing member (151) may be disposed on an upper surface (e.g., a surface in the +Z direction) of the first housing (111).

[0092] In one embodiment, the terminal (126) may be fixedly arranged on the bottom of the case (155). The terminal (126) may protrude upward from the case (155) toward the atomizing space (115) and be connected to the heater (120). The terminals (126) may be provided as a pair spaced horizontally from each other.

[0093] In one embodiment, the air inlet (155a) may be connected to the exterior of the first housing (111). The air inlet (155a) may supply air to the atomizing space (115). The air inlet (155a) may be formed at the bottom of the case (155).

[0094] In one embodiment, the air inlet (155a) may be formed in multiple numbers to form a multi-hole shape. The air inlet (155a) may be spaced apart horizontally from the terminal (126).

[0096] In one embodiment, the second wick part (121b) may be positioned to penetrate the first sealing member (151). The second wick part (121b) may be exposed to the outside of the first housing (111). The second wick part (121b) may be an area that receives an aerosol generating material from the second housing (112).

[0097] In one embodiment, the heater (120) may be coupled to the first wick part (121a). For example, the heater (120) may be insert-coupled to the lower surface (e.g., the surface in the -Z direction) of the first wick part (121a). The heater (120) may heat the first wick part (121a).

[0098] In one embodiment, the first sealing member (151) may cover the upper surface of the case (155). The first sealing member (151) may be formed of an elastic material. For example, the first sealing member (151) may be formed of a rubber or silicone material.

[0099] In one embodiment, the first sealing member (151) may include a sealing surface (151a). The sealing surface (151a) may have a shape that surrounds the outer circumference of the second wick part (121b) of the wick (121).

[0100] In one embodiment, the wick (121) may be formed of a porous rigid body that absorbs aerosol-generating substances. For example, the wick (121) may be formed of porous ceramic. The wick (121) may have greater rigidity and heat resistance than a wick made of cotton. The wick (121) may be formed of a material that does not deform or has minimal deformation. In addition, the durability of the wick (121) may be improved, and the replacement cycle of the first housing (111) to which the wick (121) is coupled may be increased.

[0101] In one embodiment, the first wick part (121a) may be elongated in one horizontal direction (e.g., in the X-axis direction). The first wick part (121a) may have a hexahedral shape. The upper and lower surfaces of the first wick part (121a) may be formed substantially horizontally. The side surface of the first wick part (121a) may be formed between the upper and lower surfaces.

[0102] In one embodiment, the second wick part (121b) may protrude upward from the center of the upper surface of the first wick part (121a).

The two second wick parts (121b) may be arranged spaced apart from each other.

[0103] In one embodiment, the lower surface of the second wick part (121b) may overlap the upper surface of the first wick part (121a). The first wick part (121a) and the second wick part (121b) may be formed as a single body that is continuous with each other. Alternatively, the first wick part (121a) and the second wick part (121b) may be formed by being mutually coupled.

[0104] In one embodiment, the heater (120) may be attached to the first wick part (121a). The heater (120) may form a pattern on the lower surface of the first wick part (121a). For example, the heater (120) may form various patterns along the longitudinal direction of the first wick part (121a).

[0105] In one embodiment, the airflow inlet (155a) and the first aerosol flow path (119) may be arranged in parallel in the vertical direction (e.g., Z-axis direction). For example, the airflow inlet (155a) may be formed at the lower side of the atomization space (115). The first aerosol flow path (119) may be formed at the upper side of the atomization space (115). Air may be introduced into the atomization space (115) through the airflow inlet (155a) and discharged to the outside of the atomization space (115) through the first aerosol flow path (119). The aerosol generated when the wick (121) is heated and the air surrounding it may flow toward the first aerosol flow path (119).

[0106] In one embodiment, the second sealing member (152) may be disposed on a lower surface (e.g., a surface in the -Z direction) of the second housing (112). The second sealing member (152) may be disposed to surround at least a portion of the first housing (111) and the first sealing member (151) when the first housing (111) and the second housing (112) are coupled. The second sealing member (152) may form a second aerosol passage (129) that is open inward.

[0107] In one embodiment, the second sealing member (152) may be a portion or a structure of the second housing (112). For example, the second sealing member (152) may be formed integrally with the lower surface of the second housing (112), and may be a portion surrounding the absorbent member (158) exposed to the lower surface of the second housing (112).

[0108] In one embodiment, the chamber hole (127a) may be connected to the chamber (127). The chamber hole (127a) may be formed at the bottom of the chamber (127). The aerosol generating material stored in the chamber (127) may pass through the chamber hole (127a) and be delivered to the wick (121).

[0109] In one embodiment, the absorbent member (158) may be positioned at the bottom of the chamber hole (127a). The absorbent member (158) may absorb an aerosol generating substance passing through the chamber hole (127a). For example, the absorbent member (158) may be formed of a felt material. When the first housing (111) and the second housing (112) are combined, the absorbent member (158) and the second wick part (121b) may face each other.

[0110] In one embodiment, a protective film may be detachably attached to the lower surface of the absorbent member (158). The protective film may be made of a waterproof material. The protective film may prevent aerosol generating substances from leaking from the absorbent member (158). Before attaching the second housing (112) to the first housing (111), the user may remove the protective film from the absorbent member (158).

[0111] In one embodiment, when the second housing (112) is coupled with the first housing (111), the second housing (112) can supply an aerosol generating substance to the wick (121). For example, the aerosol generating substance stored in the chamber (127) passes through the chamber hole (127a) and is absorbed by the absorbent member (158), and the absorbent member (158) that has absorbed the aerosol generating substance can contact the second wick part (121b) to transfer the aerosol generating substance. The aerosol generating substance absorbed by the second wick part (121b) can diffuse to the first wick part (121a). The heater (120) can heat the first wick part (121a) that has absorbed the aerosol generating substance to generate an aerosol.

[0112] In one embodiment, the first sealing member (151) can seal a portion of the wick (121) that protrudes outward from the atomizing space (115). When the second housing (112) is coupled to the upper side of the first housing (111), the first sealing member (151) can seal between the first housing (111) and the second housing (112).

[0113] In one embodiment, a switch (170) may be connected to a heater (125). The switch (170) may control operation of the heater (125). For example, when the switch (170) is turned on or electrically shorted, power and / or an electrical signal may be supplied to the heater (125).

[0114] In one embodiment, the second housing (112) may include a pressure member (160). The pressure member (160) may be formed on one surface (e.g., a surface in the -Z direction) of the second housing (112) that is coupled with the first housing (111). The pressure member (160) may have a shape that protrudes in the direction in which it is coupled with the first housing (111).

[0115] In one embodiment, the switch (170) may be provided in the first housing (111). The first housing (111) may include at least one of a receiving space (161), an insertion hole (163), and a sealing film (165). The receiving space (161) may be a portion of the first housing (111) for receiving the switch (170).

[0116] In one embodiment, the insertion hole (163) may be formed on one side (e.g., the side in the +Z direction) of the second housing (112) that is coupled with the first housing (111). The insertion hole (163) may have a shape that is open in the direction in which it is coupled with the first housing (111).

[0117] In one embodiment, the insertion hole (163) may be connected from the receiving space (161) to the exterior of the second housing (112). When the first housing (111) and the second housing (112) are coupled, the pressure member (160) may be inserted into the insertion hole (163).

[0118] In one embodiment, the sealing film (165) may be placed in the insertion hole (163) or the receiving space (161). The sealing film (165) may open the insertion hole (163) when the pressing member (160) is inserted, and may seal the insertion hole (163) when the pressing member (160) is withdrawn. The sealing film (165) may be formed of a movable elastic film or an elastic plate.

[0120] Referring to FIGS. 4a, 4b, 4c and 4d, a switch (170) according to one embodiment may include a first conductive member (171), a second conductive member (172) and a moving member (173).

[0121] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it will be understood that some configurations and structures of the switch (170) and the aerosol generating device (100) including the switch (170) may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the above-described embodiments may be combined with the switch (170) and the aerosol generating device (100) including the switch (170) unless it is technically clearly impossible.

[0122] For example, the switch (170) of FIGS. 4a, 4b, 4c, and 4d and the aerosol generating device (100) including the switch (170) of FIGS. 3a, 3b, 3c, 3d, and 3e and the aerosol generating device (100) including the switch (170) of FIGS. 3a, 3b, 3c, 3d, and 3e may be substantially the same, or at least some of the configurations may be omitted, added, or replaced.

[0123] "Substantially" in this document may mean the same level, reflecting tolerances or errors in typical manufacturing processes. Alternatively, "substantially" may refer to a range including any of + / -0.1%, + / -0.5%, + / -1%, + / -3%, + / -5%, + / -7%, + / -10%, + / -15%, and + / -20%, relative to the literal equivalent of 0%.

[0124] In one embodiment, the first conductive member (171) and the second conductive member (172) may be disposed in the first housing (111). At least one of the first conductive member (171) and the second conductive member (172) may be directly or indirectly connected to the heater (125).

[0125] For example, one of the first conductive member (171) and the second conductive member (172) may be connected to the heater (125) or the terminal (126), and the other may be connected to the battery (105) or the control unit (107).

[0126] In one embodiment, the first conductive member (171) and the second conductive member (172) may be arranged to be spaced apart from each other. The first conductive member (171) and the second conductive member (172) may not be directly connected and may be electrically isolated from each other. The first conductive member (171) and the second conductive member (172) may be optionally connected by another configuration (e.g., a movable member (173)).

[0127] In one embodiment, the first conductive member (171) and the second conductive member (172) may have a shape extending along the moving direction of the moving member (173). For example, as illustrated in the drawing, the first conductive member (171) and the second conductive member (172) may have a connector or terminal shape protruding upward (e.g., in the +Z direction). In one embodiment, the first conductive member (171) and the second conductive member (172) may have substantially the same shape.

[0128] In one embodiment, the movable member (173) can electrically connect the first conductive member (171) and the second conductive member (172). For example, the movable member (173) can be moved by being pressed by the pressing member (160) when the first housing (111) and the second housing (112) are coupled.

[0129] In one embodiment of the present document, the switch (170) can be formed with a simple and easy structure using only a first conductive member (171), a second conductive member (172), and a moving member (173). For example, if a separate optical sensor or physical sensor other than the switch (170) is used, additional circuit design may be required. The switch (170) according to one embodiment of the present document can improve manufacturing difficulty and provide manufacturing efficiency and economy.

[0130] Hereinafter, the structure of a switch (170) according to one embodiment will be described with reference to the drawings, but this is merely an example, and the actual implementation of the switch (170) is not limited thereto.

[0131] In one embodiment, the movable member (173) may include a first contact terminal (173a) and a second contact terminal (173b). The first contact terminal (173a) may be in constant contact with the first conductive member (171). The second contact terminal (173b) may be in contact with the second conductive member (172) when the movable member (173) is moved by the pressing member (160).

[0132] For example, as illustrated in FIGS. 4c and 4d, the first contact terminal (173a) and the second contact terminal (173b) may be disposed to be spaced apart from each other. The first contact terminal (173a) may be maintained in contact with the first conductive member (171). The second contact terminal (173b) may be disposed to be spaced apart from the second conductive member (172) in an upward direction (e.g., in the +Z direction). When the moving member (173) is pressed, the second contact terminal (173b) moves together with the moving member (173) in a moving direction (e.g., in the -Z direction) and may come into physical or electrical contact with the second conductive member (172).

[0133] In one embodiment of the present document, through the physical structure of the first contact terminal (173a) and the second contact terminal (173b), the switch (170) can structurally control the electrical connection of the first conductive member (171) and the second conductive member (172) by the movement of the moving member (173) by the pressing member (160).

[0134] In one embodiment, the movable member (173) may be connected to the first conductive member (171) and supported by the first conductive member (171). As illustrated in FIG. 4B, the movable member (173) may be structurally connected to the first conductive member (171). The switch (170) may implement the connection and support structure of the movable member (173) through the structural design of the movable member (173) without including a separate coupling component.

[0135] In one embodiment, the moving member (173) may include a guide region (175). The guide region (175) may be arranged to surround at least a portion of the first conductive member (171). The guide region (175) may have a shape extending along the direction in which it moves by the pressing member (160).

[0136] For example, the first conductive member (171) may have a columnar shape extending upward (e.g., in the +Z direction). The guide region (175) may have a shape surrounding a portion of the upper side of the first conductive member (171). The guide region (175) may guide the direction in which the moving member (173) moves.

[0137] In one embodiment, the first conductive member (171) may include a disengagement prevention groove (171a). The disengagement prevention groove (171a) may be a groove or hole extending along the movement direction (e.g., Z-axis direction) of the movable member (173).

[0138] In one embodiment, the movable member (173) may include a protruding region (176). The protruding region (176) may be positioned within the anti-separation groove (171a). The protruding region (176) may limit the range of movement of the movable member (173). For example, if the protruding region (176) contacts either end of the anti-separation groove (171a), the movement of the movable member (173) may be limited.

[0139] In one embodiment, the movable member (173) may include a plate spring region (177). The plate spring region (177) may have a curved shape as it extends along the movement direction of the movable member (173). As the movable member (173) moves by the pressure member (160), the plate spring region (177) may gradually bend and the elastic force may increase. When the pressure member (160) is removed, the movable member (173) may be restored to its original position by the elastic force of the plate spring region (177).

[0140] In one embodiment of the present document, the movable member (173) can form its own restoring force through the plate spring region (177). By the movable member (173) including the plate spring region (177) by itself, the switch (170) can improve manufacturing difficulty and provide manufacturing efficiency and economy.

[0141] In one embodiment, the first contact terminal (173a) and the second contact terminal (173b) may be provided at the end of the plate spring region (177). The first contact terminal (173a) and the second contact terminal (173b) may be formed adjacent to each other at the lower end of the plate spring region (177). When the moving member (173) moves by the pressing member (160), the plate spring region (177) bends and moves downward, and the second contact terminal (173b) may come into contact with the second conductive member (172).

[0142] In one embodiment, the moving member (173) may include a pressure surface (174). The pressure surface (174) may be provided in a direction facing the pressure member (160) from the moving member (173). The pressure surface (174) may have a substantially flat plate shape or a shape corresponding to the end structure of the pressure member (160).

[0143] In one embodiment, the pressure surface (174) may have a structure that is temporarily deformable when pressed by the pressure member (160). For example, as shown in FIG. 4A, one end of the pressure surface (174) may be fixed to the movable member (173), and the other end of the pressure surface (174) may be formed as a free end. When pressed by the pressure member (160), the pressure surface (174) may be deformed to bend or slope at a predetermined interval. The pressure surface (174) may absorb at least a portion of the pressure exerted by the pressure member (160).

[0144] In one embodiment, the movable member (173) may be formed of a single continuous conductive material. For example, the various components of the movable member (173) described above may be formed as a single continuous structure. The movable member (173) may not only function as a conductive structure that electrically connects the first conductive member (171) and the second conductive member (172), but may also perform at least one of the functions of an elastic body, a guide member, and a separation prevention member.

[0145] In one embodiment, the movable member (173) may be formed of a non-conductive or weakly conductive material having at least a portion of the surface coated with a conductive material. For example, the movable member (173) may be formed of stainless steel, carbon, or an elastomer. The outer surface of the movable member (173) may be coated with a conductive material. Alternatively, the first contact terminal (173a) and the second contact terminal (173b) of the outer surface of the movable member (173), and at least a portion of the surface that electrically connects them, may be coated with a conductive material.

[0146] FIG. 5a is a cross-sectional view of a switch (170) in a pre-pressurized state according to one embodiment, and FIG. 5b is a cross-sectional view of a switch (170) in a pressurized state according to one embodiment.

[0147] Referring to FIGS. 5a and 5b, a switch (170) according to one embodiment may further include a conductive region (178b).

[0148] Hereinafter, any content that overlaps with the above-described content will be omitted for explanation, and it will be understood that some configurations and structures of the switch (170) and the aerosol generating device (100) including the switch (170) may be replaced, added, or omitted within a range that can be easily understood by those skilled in the art by referring to the drawings and descriptions below. In addition, at least one configuration or feature of the above-described embodiments may be combined with the switch (170) and the aerosol generating device (100) including the switch (170) unless it is technically clearly impossible.

[0149] In one embodiment, the movable member (173) may be composed of a body (178a) and a conductive region (178b). The body (178a) may be composed of a non-conductive material. The movable member (173) may prevent discharge or short circuit caused by foreign substances or moisture in unnecessary areas, and may also improve the durability and corrosion resistance of the movable member (173).

[0150] In one embodiment, a conductive region (178b) may be coupled to the body (178a). The conductive region (178b) may be formed of a conductive material. The first conductive member (171) and the second conductive member (172) may be selectively interconnected by the conductive region (178b).

[0151] In one embodiment, when the movable member (173) is moved by the pressure member (160), it can simultaneously contact the first conductive member (171) and the second conductive member (172). For example, referring to FIGS. 4c and 4d, the first contact terminal (173a) and the second contact terminal (173b) and some areas connecting them can be formed as conductive areas (178b).

[0152] Alternatively, for example, the conductive region (178b) may be coupled to the lower surface of the pressing surface (174). When the pressing surface (174) is pressed and moved by the pressing member (160), the conductive region (178b) may move and come into contact with the first conductive member (171) and the second conductive member (172). In this case, the first contact terminal (173a) and the second contact terminal (173b) may be omitted.

[0153] In one embodiment, the protruding region (176) may be formed as a hook structure in which the end of the protruding region (176) is inserted into the anti-separation groove (171a). For example, before the moving member (173) is pressed by the pressing member (160), the moving member (173) may be pressed upward (e.g., in the +Z direction) by the plate spring region (177). The end of the hook structure of the protruding region (176) may be arranged to contact the upper end of the anti-separation groove (171a), thereby restricting the movement of the moving member (173).

[0154] In one embodiment of the present document, the protruding region (176) structurally suggests a range of movement of the movable member (173) through a hook structure, and can prevent the movable member (173) from being detached from or over-inserted in the switch (170).

[0155] Any or all of the embodiments of the present disclosure described above are not mutually exclusive or distinct. Any or all of the embodiments of the present disclosure described above may have their respective components or functions combined or used together.

[0156] For example, it means that a configuration A described in a particular embodiment and / or drawing can be combined with a configuration B described in another embodiment and / or drawing. That is, even if a combination between configurations is not directly described, it means that a combination is possible, except in cases where a combination is described as impossible.

[0157] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
