[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to the Chinese patent application No. 202411098701.3, filed on August 9, 2024, entitled “Aerosol substrate reservoir and aerosol-generating device comprising the same”, the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0004] The present application relates to the field of aerosol generation technology, in particular to an aerosol substrate reservoir and an aerosol-generating device comprising the same. BACKGROUND

[0005] An aerosol-generating device is a device capable of atomizing an aerosol-generating formulation to form an aerosol. The aerosol-generating device is produced independently of the article containing the aerosol-generating formulation, so that before use, the aerosol-generating device and the article containing the aerosol-generating formulation are stored separately, and when in use, the aerosol-generating device and the article containing the aerosol-generating formulation are joined together.

[0006] In some exemplary prior art, the article containing the aerosol-generating formulation further comprises a flow guide hole for guiding the aerosol-generating formulation and a soft plug for shielding the flow guide hole. A part of the soft plug is exposed externally to allow a user to pull out the soft plug before the article is joined with the aerosol-generating device.

[0007] However, when the article is obtained by a person who is not intended to use, such as a child, the soft plug can be easily pulled out of the flow guide hole by a simple operation, causing the aerosol-generating formulation to leak.

[0008]

Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0065] Reference herein to "embodiments" means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0066] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" or "coupled" to another element, it can be directly connected to the other element or intervening elements can also be present. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0067] Referring to FIGS. 1-11, some embodiments of the present application provide an aerosol substrate reservoir 1, which is a container capable of storing an aerosol generating substrate. The aerosol substrate reservoir 1 can be combined with an atomization assembly 2 to form an aerosol generating device, and after being combined, the aerosol substrate reservoir 1 can provide the atomization assembly 2 in the aerosol generating device with the aerosol generating substrate for the atomization assembly 2 to atomize to generate an aerosol.

[0068] Referring to FIGS. 2-5 and 7-10, the aerosol substrate reservoir 1 includes a main body assembly 11 having a storage cavity for accommodating an aerosol generating substrate. The aerosol generating substrate can be stored in the storage cavity by injection or filling, etc.

[0069] In some embodiments, the aerosol generating substrate includes a liquid substrate, which can include a liquid containing a tobacco-containing substance having a volatile tobacco flavor component, and can also include a liquid containing a non-tobacco substance. The liquid substrate can include water, a medicinal liquid, a solvent, ethanol, a plant extract, a flavoring, a flavoring agent, or a vitamin mixture, etc. The flavoring can include areca extract, menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent can include components that can provide various flavors or tastes to the user. The vitamin mixture can be a mixture mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto. Based on different properties of the liquid substrate, the aerosol substrate reservoir can be used in different fields, such as medical, electronic aerosol atomization, etc.

[0070] When the aerosol generating substrate includes a liquid substrate, the main body assembly 11 can further include a liquid storage cotton 111 disposed in the storage cavity, the liquid storage cotton 111 being used to absorb the liquid substrate, and helping to confine the liquid substrate in the liquid storage cotton 111, so as to be able to prevent the liquid substrate from leaking from the storage cavity. It should be noted that the liquid storage cotton 111 is optional but not mandatory.

[0071] Referring to FIGS. 4 and 5, the main body assembly 11 is provided with a flow guide hole 112 for guiding the aerosol generating substrate out of the storage cavity.

[0072] The atomization assembly 2 can have no chamber for storing the aerosol generating substrate, and thus, when the atomization assembly 2 is not engaged with the aerosol substrate reservoir 1, the aerosol cannot be generated. After the atomization assembly 2 is engaged with the aerosol substrate reservoir 1, the atomization assembly 2 is connected with the flow guide hole 112, and the aerosol generating substrate contained in the main body assembly 11 can flow into the atomization assembly 2 to be atomized by the atomization assembly 2.

[0073] The atomization assembly 2 can have a chamber for storing the aerosol generating substrate and an atomization core for atomizing the liquid substrate, the atomization core being in fluid communication with the chamber, so that the atomization core can transport and atomize the aerosol generating substrate in the chamber. After the atomization assembly 2 is engaged with the aerosol substrate reservoir 1, the atomization assembly 2 is connected with the flow guide hole 112, and the aerosol generating substrate in the aerosol substrate reservoir 1 can flow into the chamber of the atomization assembly 2, so as to replenish the chamber with the aerosol generating substrate.

[0074] As an exemplary embodiment, the atomizing core can include a liquid absorbing element and a heating element, the heating element being arranged on the liquid absorbing element. The liquid absorbing element can be a porous body for guiding the liquid substrate into the atomization range of the heating element. The heating element is used to heat the atomized aerosol generating substrate, thereby generating the aerosol. The porous body can be a fiber, such as a cotton fiber, a polypropylene fiber, a polyester fiber, or a nylon fiber, etc. The porous body can be a porous ceramic or a porous metal, and the present application does not limit the structure and composition of the porous body.

[0075] As an exemplary embodiment, the atomizing core can include an ultrasonic element capable of high-frequency vibration under ultrasonic driving, and the atomizing core atomizes the liquid substrate to form the aerosol by ultrasonic vibration. Of course, the atomizing core can also include other elements capable of atomizing the liquid substrate to form the aerosol.

[0076] The aerosol generating device can further include a power supply assembly 3 electrically connectable with the atomizing assembly 2 to provide power for the atomizing assembly 2 to atomize the aerosol generating substrate. The power supply assembly 3 can include any suitable battery, such as a rechargeable battery, and of course, a disposable battery.

[0077] Referring to FIGS. 2-10, the aerosol substrate reservoir 1 further includes a blocking assembly 12 for blocking the flow guide hole 112 of the main body assembly 11 when the aerosol substrate reservoir 1 is stored alone, so as to prevent the flow guide hole 112 from being open, thereby preventing the aerosol generating substrate in the storage chamber 111 from leaking through the flow guide hole 112.

[0078] More specifically, the blocking assembly 12 can block the flow guide hole 112 before the blocking assembly 12 is removed from the main body assembly 11. The main body assembly 11 includes a fitting portion 117, and the blocking assembly 12 includes a cover 121 rotatable relative to the main body assembly 11, and the cover 121 can be removed from the main body assembly 11 in the longitudinal direction when the cover 121 is rotated to a first position relative to the main body assembly 11. The cover 121 can have an interference portion 1213 thereon, and the interference portion 1213 interferes with the fitting portion 117 in the longitudinal direction when the cover 121 is rotated to a second position relative to the main body assembly 11, and the interference portion 1213 and the fitting portion 117 can abut each other in the longitudinal direction when a force in the removal direction is applied, thereby preventing the cover 121 from being removed from the main body assembly 11.

[0079] In order to prevent the cover 121 from being rotated relative to the main body assembly 11 in an undesired manner:

[0080] In some embodiments, a shallow groove is provided on one of the cover and the main body assembly, and a protrusion is provided on the other one, the protrusion is fitted in the shallow groove to prevent the cover from rotating relative to the main body assembly to a certain extent, and when the cover is driven by a large force, the protrusion can be moved out of the shallow groove in the rotating direction, and then the cover can rotate relative to the main body assembly more freely; however, this way will not only make the cover emit a harsh sound during the rotation relative to the main body assembly, but also not conducive to providing a good operation feel.

[0081] Alternatively, in some embodiments, referring to FIGS. 4-10, the blocking assembly 12 further includes a support member 122 configured to support the cover 121 in the longitudinal direction to provide a support force to make the interference portion 1213 abut against the cooperating portion 117. On the one hand, when the blocking assembly 12 is pressed against the main body assembly 11 in the longitudinal direction, the support member 122 can yield in the opposite direction in the longitudinal direction, and when the pressing of the blocking assembly 12 against the main body assembly 11 in the longitudinal direction is cancelled or reduced, the support member 122 can return or move or deform towards the return direction in the longitudinal direction; on the other hand, the interference portion 1213 and the cooperating portion 117 have a large interference fit force in the longitudinal direction, which can provide resistance to the cover 121 in the opposite direction of the rotating direction, and can prevent the cover 121 from rotating relative to the main body assembly 11 to a certain extent when the interference portion 1213 abuts against the cooperating portion 117, so that the blocking assembly 12 can provide a damping feel to the user during the rotation of the cover 121 relative to the main body assembly 11, and can also prevent a harsh sound from being emitted during the rotation of the cover 121 relative to the main body assembly 11.

[0082] In some embodiments, the flow guide hole 112 on the main body assembly 11 is closed in the initial state, and after the blocking assembly 12 is removed from the main body assembly 11, the flow guide hole 112 needs to be opened by other operations, so that the aerosol generating substrate in the storage cavity can flow out through the flow guide hole 112. For example, the flow guide hole 112 has a seal film that can be pierced, and before the seal film is pierced, the seal film can isolate the storage cavity from the outside, so that the aerosol generating substrate cannot flow out through the flow guide hole 112; wherein the seal film can be pierced by the atomization assembly 2 during the engagement of the aerosol substrate reservoir 1 and the atomization assembly 2, so that after the engagement of the aerosol substrate reservoir 1 and the atomization assembly 2, the aerosol generating substrate in the aerosol substrate reservoir 1 can be atomized by the atomization assembly 2 through the connection between the atomization assembly 2 and the flow guide hole 112. Therefore, when the blocking assembly 12 is connected to the main body assembly 11, the blocking assembly 12 prevents the flow guide hole 112 from being accidentally pierced by shielding the flow guide hole 112.

[0083] In some embodiments, referring to FIGS. 4 and 5, 7-9, the flow guide hole 112 on the main body assembly 11 is open in the initial state, and after the blocking assembly 12 is removed from the main body assembly 11, the aerosol generating substrate in the storage cavity 111 can flow out through the flow guide hole 112. Based on this, the blocking assembly 12 can further include a flexible plug 123, which is used to seal the flow guide hole 112. For example, when the interference portion 1213 and the matching portion 117 abut each other in the longitudinal direction, the flexible plug 123 can interfere with the main body assembly 11, thereby blocking the flow guide hole 112 or blocking the communication between the flow guide hole 112 and the outside.

[0084] In some embodiments, during the rotation of the cover 121 relative to the main body assembly 11, the flexible plug 123 can keep sealing the flow guide hole 112 to prevent the aerosol generating substrate in the storage cavity from leaking through the flow guide hole 112 during the rotation of the cover 121 relative to the main body assembly 11.

[0085] Based on this, during the rotation of the cover 121 relative to the main body assembly 11, the relative coordinate position between the flexible plug 123 and the cover 121 can remain unchanged. For example, when the cover 121 includes a bottom wall 1211, during the rotation of the cover 121 relative to the main body assembly 11, the distance between the flexible plug 123 and the bottom wall 1211 remains unchanged, or the bottom wall 1211 supports the flexible plug 123 in the longitudinal direction. It should be noted that when the relative coordinate position between the flexible plug 123 and the cover 121 remains unchanged, the flexible plug 123 can rotate in place relative to the cover 121, and / or the flexible plug 123 can elastically deform.

[0086] In some embodiments, the main body assembly 11 and the flexible plug 123 are embeddedly connected, so that the main body assembly 11 and the flexible plug 123 can interfere with each other in the transverse direction, and the flexible plug 123 is rotatably arranged in the cover 121, and the cover 121 is configured to rotate relative to the flexible plug 123 while rotating relative to the main body assembly 11. During the rotation of the cover 121 relative to the main body assembly 11, the flexible plug 123 and the main body assembly 11 can be relatively stationary, which is conducive to making the sealing of the flexible plug 123 to the flow guide hole 112 reliable and stable.

[0087] In embodiments as shown in Figs. 3-5 and 10, the flexible plug 123 is provided with a receiving cavity 1231, the body assembly 11 includes a protrusion 118 which is hollow and the interior of the protrusion 118 is in fluid communication with the storage cavity 111, and the flow guide hole 112 is formed in the wall of the protrusion 118. When the blocking assembly 12 is connected to the body assembly 11, at least part of the protrusion 118 is located in the receiving cavity 1231 and is in interference fit with the flexible plug 123, so that the flexible plug 123 mainly blocks the flow guide hole 112 from the outside of the flow guide hole 112. For example, the flow guide hole 112 can be formed in the side wall of the protrusion 118, and the flow guide hole 112 is located in the receiving cavity 1231 and is surrounded by the flexible plug 123, because the protrusion 118 is in interference fit with the flexible plug 123, so that the flexible plug 123 can block the flow guide hole 112 from the outside of the flow guide hole 112. For example, the flow guide hole 112 can be formed in the end wall of the protrusion 118, the receiving cavity 1231 is a blind hole, and the flow guide hole 112 is located in the receiving cavity 1231 and is arranged towards the bottom of the receiving cavity 1231, because the protrusion 118 is in interference fit with the flexible plug 123, so that the flexible plug 123 can prevent the flow guide hole 112 from being in communication with the outside.

[0088] Preferably, the protrusion 118 extends in the longitudinal direction. In some embodiments, the protrusion 118 can have a plurality, and each protrusion 118 can be embedded in a receiving cavity 1231, so that after at least part of the protrusion 118 is embedded in the receiving cavity 1231, the protrusion 118 can drive the flexible plug 123 to rotate relative to the cover 121 by interference fit with the receiving cavity 1231 when the cover 121 is rotated relative to the body assembly 11. In this embodiment, part of the protrusion 118 can not be provided with a flow guide hole 112, and of course all protrusions 118 can be provided with a flow guide hole 112.

[0089] In some embodiments, the flexible plug 123 is configured to be removably arranged in the cover 121, and the flexible plug 123 is connected to the body assembly 11 by interference fit, so as to remain connected to the body assembly 11 and continue to seal the flow guide hole 112 after the cover 121 is removed from the body assembly 11, which helps to prevent the aerosol generating substrate in the storage cavity from leaking through the flow guide hole 112 during the process of removing the cover 121 from the body assembly 11. In other words, removing the blocking assembly 12 from the body assembly 11 can be carried out in steps, and the cover 121 can be removed from the body assembly 11 first, and then the flexible plug 123 can be removed from the body assembly 11.

[0090] In the embodiments shown in FIGS. 4, 5, 7 and 8, the cover 121 comprises an annular sidewall 1212, the flexible plug 123 is located inside the annular sidewall 1212 and is spaced apart from the annular sidewall 1212, so that the annular sidewall 1212 does not interfere with the connection between the flexible plug 123 and the main body assembly 12 during the removal of the cover 121 from the main body assembly 11.

[0091] In some embodiments, referring to FIGS. 4-10, the support member 122 comprises a damping member 1221 which is elastically deformable or displaceable in the longitudinal direction, so that the support member 122 is floating in the longitudinal direction to provide floating support for the main body assembly 11. And / or, the damping member 1221 can provide resistance to the cover 121 in the opposite direction of rotation, so as to further prevent the cover 121 from making a harsh sound during rotation.

[0092] In some embodiments, the flexible plug 123 is elastic, for example, the flexible plug 123 can be made of silica gel. Therefore, the connection between the flexible plug 123 and the main body assembly 11 is an elastic connection. The flexible plug 123 can be elastically deformed between the main body assembly 11 and the cover 121. The flexible plug 123 can be elastically deformed in the longitudinal direction.

[0093] Further, the flexible plug 123 can be a component of the support member 122, for example, the damping member 1221 in the support member 122 can comprise the flexible plug 123. The flexible plug 123 can not only seal the flow guide hole 112, but also floatingly support the main body assembly 11 in the longitudinal direction, while also providing resistance to the cover 121 in the opposite direction of rotation to prevent abnormal sound.

[0094] In some embodiments, referring to FIGS. 7-10, the flexible plug 123 or the damping member 1221 comprises a first part 1232 and a second part 1233 connected to the first part 1232, which is elastically deformable when the flexible plug 123 or the damping member 1221 is pressed. The elastic deformation can include an elastic deformation of the angle between the first part 1232 and the second part 1233, for example, the angle between the first part 1232 and the second part 1233 is larger after deformation than before deformation. The elastic deformation can include a bending deformation of the first part 1232 or the second part 1233, or a change in the degree of bending.

[0095] In some embodiments, referring to FIGS. 7-10, the second part 1233 comprises a bendingly arranged elastic arm, one of the elastic arm and the first part 1232 abuts the cover 121, and the other abuts the main body assembly 11.

[0096] The first portion 1232 can be substantially block-shaped. The elastic arm can be substantially bent strip-shaped or substantially bent rod-shaped. The elastic arm is more easily elastically deformed than the first portion 1232, or the elastic arm has a smaller elastic coefficient than the first portion 1232. When the flexible plug 123 or the damping member 1221 is elastically deformed, the bending angle of the elastic arm can be elastically deformed.

[0097] The elastic arm can include a first elastic arm 12331 connected with the first portion 1232 and a second elastic arm 12332 bent relative to the first elastic arm 12331 and connected with the first elastic arm 12331. When the flexible plug 123 or the damping member 1221 is in a natural state, the included angle between the first elastic arm 12331 and the first portion 1232 can be substantially 90°. When the flexible plug 123 or the damping member 1221 is in a natural state, the included angle between the first elastic arm 12331 and the second elastic arm 12332 can be substantially 90°. When the flexible plug 123 or the damping member 1221 is in an elastically deformed state, or when the interference portion 1213 and the cooperating portion 117 abut each other in the longitudinal direction, the included angle between the first elastic arm 12331 and the first portion 1232 can be elastically expanded, of course, it can also be elastically reduced. When the flexible plug 123 or the damping member 1221 is in an elastically deformed state, or when the interference portion 1213 and the cooperating portion 117 abut each other in the longitudinal direction, the included angle between the first elastic arm 12331 and the second elastic arm 12332 can be elastically expanded, of course, it can also be elastically reduced.

[0098] The first elastic arm 12331 can extend substantially in the transverse direction in a natural state. The second elastic arm 12332 can extend substantially in the longitudinal direction in a natural state.

[0099] In the embodiments as shown in FIGS. 7-10, the first portion 1232 is used to support the main body assembly 11, and the elastic arm is used to support the bottom wall 1211 of the cover 121, specifically, the second elastic arm 12332 is used to support the bottom wall 1211 of the cover 121. The first portion 1232 can be used to seal the flow guide hole 112. The receiving cavity 1231 can be provided on the first portion 1232. The first portion 1232 can be used to support the air guide tube 116 of the main body assembly 11. The first portion 1232 can have a groove for receiving the end of the air guide tube 116.

[0100] In some embodiments, referring to FIGS. 7-10, the second portion 1233 has a plurality of second portions 1233 connected to the first portion 1232 evenly, so that the second portion 1233 can provide stable support for the first portion 1232 and the cover 121. In the embodiments shown in FIGS. 7-10, the elastic arm has two arms connected to the first portion 1232 symmetrically. The first portion 1232 and the second portion 1233 can be made of the same material. The first portion 1232 and the second portion 1233 can be integrally injection molded.

[0101] When the flexible plug 123 or the damping member 1221 is in a natural state (see FIGS. 8-10), the flexible plug 123 or the damping member 1221 has a first height in the longitudinal direction. When the interference portion 1213 and the cooperating portion 117 abut each other in the longitudinal direction, or when the flexible plug 123 or the damping member 1221 is elastically deformed (see FIG. 7), the height of the flexible plug 123 or the damping member 1221 in the longitudinal direction is reduced, which is lower than the first height. The reduction of the height of the flexible plug 123 or the damping member 1221 in the longitudinal direction can be mainly caused by the change of the opening angle between the first portion 1232 and the second portion 1233, or can be mainly caused by the change of the bending degree of the elastic arm.

[0102] When the cover 121 includes the bottom wall 1211, the bottom wall 1211 can directly support the flexible plug 123. Further, referring to FIG. 8, when the flexible plug 123 is in a natural state, the bottom wall 1211 directly supports the second portion 1233 of the flexible plug 123, and the bottom wall 1211 is spaced apart from the first portion 1232 of the flexible plug 123; referring to FIG. 7, when the interference portion 1213 and the cooperating portion 117 abut each other in the longitudinal direction, the second portion 1233 is elastically deformed, and / or the opening angle between the first portion 1232 and the second portion 1233 is elastically deformed, so that the distance between the bottom wall 1211 and the first portion 1232 is reduced or even the bottom wall 1211 directly contacts the first portion 1232.

[0103] It should be noted that the use of the bottom wall 1211 to directly support the flexible plug 123 is optional and not mandatory, and in other embodiments, the support member 1222 in the support member 122 can be used instead of the bottom wall 1211 to support the flexible plug 123.

[0104] In some embodiments, not shown, the damping member includes a first magnetic member, the main body assembly includes a second magnetic member, and when the main body assembly and the locking assembly are connected, the first magnetic member and the second magnetic member have a magnetic repulsion force, and the first magnetic member is configured to be movable in the longitudinal direction in the cover.

[0105] In some embodiments, the damping member includes a first magnetic member, the locking assembly further includes a third magnetic member, the first magnetic member and the third magnetic member have magnetic repulsion or have magnetic attraction, and the first magnetic member is configured to be movable in the cover member in the longitudinal direction.

[0106] In some embodiments, referring to FIGS. 4 and 5, the damping member 1221 includes an elastic member. The elastic member is independent of the flexible plug 123. The elastic member can be a spring or can be a silicone product. The elastic member can be elastically deformed in the longitudinal direction. The elastic member can directly abut the body assembly 11 to provide direct floating support for the body assembly 11. The elastic member can indirectly abut the body assembly 11 through the support member 1222 to provide indirect floating support for the body assembly 11.

[0107] In summary, the damping member 1221 can provide a support force in the longitudinal direction for the body assembly 11. The size of the longitudinal support force provided by the damping member 1221 for the body assembly 11 can be related to the connection depth of the locking assembly 12 and the body assembly 11 in the longitudinal direction, thereby being able to provide a good damping feel. For example, the smaller the longitudinal spacing between the bottom wall 1211 of the cover member 121 and the body assembly 11, the greater the longitudinal support force provided by the damping member 1221 for the body assembly 11. The damping member 1221 can directly abut the body assembly 11 or can indirectly abut the body assembly 11. When the cover member 121 is in the first position, the damping member 1221 can provide an acting force to promote the cover member 121 to separate from the body assembly 11 in the longitudinal direction, for example, to pop the body assembly 11 out of the cover member 121.

[0108] In some embodiments, referring to FIGS. 4-6, the support member 122 further includes a support member 1222, the support member 1222 is arranged in linkage with the damping member 1221 and is configured to be movable in the cover member 121 in the longitudinal direction, and when the locking assembly 12 is connected with the body assembly 11, the support member 1222 abuts the body assembly 11.

[0109] In the embodiments as shown in FIGS. 4-6, the elastic member / damping member 1221 is arranged between the support member 1222 and the bottom wall 1211. When the interference portion 1213 and the cooperating portion 117 abut each other in the longitudinal direction, the support member 1222 and the bottom wall 1211 can be arranged in a spaced manner, so that the support member 1222 can move towards the direction where the bottom wall 1211 is located. In other embodiments, the first magnetic member is retained on the support member.

[0110] In some embodiments, referring to FIGS. 4-6, the blocking assembly 12 further comprises a limiting member 124 connected to the cover member 121, the limiting member 124 comprises a limiting portion 1241, the support member 1222 comprises a first support portion 12221 for supporting the main body assembly 11 and a second support portion 12222 facing the limiting portion 1241, the second support portion 12222 is arranged between the bottom wall 1211 of the cover member 121 and the limiting portion 1241 to prevent the support member 1222 from being detached from the cover member 121. The limiting portion 1241 can keep the support member 1222 connected to the cover member 121, so that when the cover member 121 is removed from the main body assembly 11, the support member 1222 can be removed together from the main body assembly 11.

[0111] In some embodiments, the cover member 121 is configured to be transformable between a locked state and an unlocked state, and in the locked state, the cover member 121 is prevented from being rotated to the first position, and in the unlocked state, the cover member 121 is allowed to be rotated to the first position; the blocking assembly 12 further comprises an operating portion 125 configured to be operated by a user to drive the cover member 121 to transform from the locked state to the unlocked state, and to drive the cover member 121 to rotate to the first position in the unlocked state. This increases the operation complexity of removing the cover member 121 from the main body assembly 11, thereby preventing children from removing the cover member 121 from the main body assembly 11.

[0112] Based on this, in some embodiments, referring to FIGS. 3 and 6, the cover member 121 further comprises a first stop portion 1214, the cover member 121 is configured to be movable relative to the main body assembly 11 from the second position to a third position along the first direction x, and to be rotatable relative to the main body assembly 11 to the first position along the second direction y; when the cover member 121 is located at the second position, at least a part of the first stop portion 1214 is arranged corresponding to the cooperating portion 117 in the second direction y to prevent the cover member 121 from being rotated to the first position; when the cover member 121 is located at the third position, the first stop portion 1214 is arranged staggered with the cooperating portion 117 in the second direction y to allow the cover member 121 to be rotated to the first position.

[0113] When the cover member 121 is located at the second position, the first stop portion 1214 can interfere with the cooperating portion 117 in the second direction y, so that the cooperating portion 117 can prevent the cover member 121 from being rotated along the second direction y.

[0114] Alternatively, when the cover member 121 is located at the second position, the first stop portion 1214 can be arranged spaced apart from the cooperating portion 117 in the second direction y, so that when the cover member 121 is driven to rotate along the second direction y, the first stop portion 1214 will be rotated to interfere with the cooperating portion 117 in the second direction y, so that the cooperating portion 117 prevents the cover member 121 from continuing to rotate along the second direction y.

[0115] When the cover 121 is in the second position, the interference portion 1213 can abut the cooperation portion 117 in the longitudinal direction.

[0116] The process of moving the cover 121 from the second position to the first position can include: pressing or pushing the operation portion 125 to move the cover 121 relative to the body assembly 11 along the first direction x, so that the first stop portion 1214 is offset from the cooperation portion 117 in the second direction y, and the cover 121 is changed from the locked state to the unlocked state; driving the cover 121 to rotate relative to the body assembly 11, so that the cooperation portion 117 passes over the first stop portion 1214; and then driving the cover 121 to rotate relative to the body assembly 11 along the second direction y, and rotating the cover 121 to the first position. The rotation direction of the cover 121 to drive the cooperation portion 117 to pass over the first stop portion 1214 can be the second direction y.

[0117] In some embodiments, the first direction x is parallel to the longitudinal direction, and the cover 121 is configured to be removed from the body assembly 11 along the reverse direction of the first direction x.

[0118] In some embodiments, referring to FIGS. 3 and 6, the interference portion 1213 includes a first interference portion 12131 and a second interference portion 12132, and the first stop portion 1214 is located between the first interference portion 12131 and the second interference portion 12132; when the second interference portion 12132 corresponds to the cooperation portion 117 in the longitudinal direction, the cover 121 is in the unlocked state. When the cover 121 is in the second position, the first interference portion 12131 can abut the cooperation portion 117 in the longitudinal direction. When at least a part of the first stop portion 1214 is arranged to correspond to the cooperation portion 117 in the second direction y, or when the cover 121 is in the locked state, the first interference portion 12131 can abut the cooperation portion 117 in the longitudinal direction.

[0119] In the embodiments shown in FIGS. 3 and 6, the first interference portion 12131 extends along the second direction y, and the width of the first interference portion 12131 in the second direction y is greater than the width of the cooperation portion 117 in the second direction y. Thus, when the cover 121 is in the second position, the cover 121 can be driven to rotate back and forth in the positive and negative directions of the second direction y by the operation portion 125, and when the cover 121 rotates back and forth in the positive and negative directions of the second direction y, the cooperation portion 117 can rotate along the first interference portion 12131, or the cooperation portion 117 can rotate closely to the first interference portion 12131.

[0120] Specifically, the cover 121 further comprises a second stop portion 1215, the first stop portion 1214 and the second stop portion 1215 are arranged on opposite sides of the first interference portion 12131, when the cover 121 is located at the second position, the cover 121 can be driven to rotate between the first stop portion 1214 and the second stop portion 1215 by the operation portion 125.

[0121] In the embodiment as shown in FIG. 3 and FIG. 6, the second interference portion 12132 extends along the second direction y, and the width of the second interference portion 12132 along the second direction y is greater than the width of the fitting portion 117 along the second direction y. Thus, when the cover 121 is in the unlocked state, the cover 121 can be driven to rotate back and forth along the second direction y by the operation portion 125, and when the cover 121 rotates back and forth along the second direction y, the fitting portion 117 can rotate along the second interference portion 12132, or the fitting portion 117 can rotate closely along the second interference portion 12132.

[0122] Specifically, the cover 121 further comprises a third stop portion 1216, the second stop portion 1215 and the third stop portion 1216 are arranged on opposite sides of the interference portion 1213, when the cover 121 is in the unlocked state, the cover 121 can be driven to rotate between the second stop portion 1215 and the third stop portion 1216 by the operation portion 125.

[0123] During the process of driving the cover 121 to move relative to the main body assembly 11 along the first direction x and the second direction y, the support member 122 can remain to provide floating support for the main body assembly 11.

[0124] In the embodiment as shown in FIG. 3 and FIG. 6, the first interference portion 12131 and the second interference portion 12132 are arranged non-collinearly, including non-collinearly and non-arcuately.

[0125] In some embodiments, referring to FIG. 4, when the cover 121 is located at the second position, the first support portion 12221 on the support member 1222 can support the flexible plug 123; referring to FIG. 5, when the second interference portion 12132 corresponds to the fitting portion 117 in the longitudinal direction, the flexible plug 123 continues to be connected with the main body assembly 11, while the support member 1222 moves relative to the cover 121 along the first direction, so that the first support portion 12221 and the flexible plug 123 are arranged spaced apart in the longitudinal direction.

[0126] In some embodiments, referring to FIG. 4, the limiting member 124 can support the flexible plug 123 when the cover 121 is in the second position; referring to FIG. 5, the flexible plug 123 continues to be connected with the main body assembly 11 while the limiting member 124 moves in the longitudinal direction synchronously with the cover 121 relative to the main body assembly 11 when the second interference portion 12132 corresponds to the cooperating portion 117 in the longitudinal direction, so that the limiting member 124 can push the flexible plug 123 to move in the reverse direction of the first direction x towards the main body assembly 11, so that the convex column 118 can be deeper into the receiving cavity 1231 on the flexible plug 123.

[0127] In some embodiments, referring to FIG. 4 and FIG. 5, the cover 121 includes an annular side wall 1212 and a bottom wall 1211 arranged at one end of the annular side wall 1212, and one end of the annular side wall 1212 is open to allow part of the main body assembly 11 to enter the cover.

[0128] The main body assembly 11 can be provided with a shoulder 119. Referring to FIG. 4, the annular side wall 1212 is arranged in the longitudinal direction away from the shoulder 119 when the cover 121 is in the second position or when the first interference portion 12131 abuts against the cooperating portion 117; referring to FIG. 5, the second interference portion 12132 can abut against the cooperating portion 117 or be spaced apart from the cooperating portion 117 when the second interference portion 12132 corresponds to the cooperating portion 117 in the longitudinal direction, and at this time, the end of the annular side wall 1212 can abut against the shoulder 119 of the main body assembly 11 to limit the distance of the cover 121 moving relative to the main body assembly 11 in the first direction x.

[0129] The supporting member 1222 can include a guide portion 1A. Referring to FIG. 4, the bottom wall 1211 is arranged in the longitudinal direction away from the guide portion 1A when the cover 121 is in the second position or when the first interference portion 12131 abuts against the cooperating portion 117; referring to FIG. 5, the second interference portion 12132 can abut against the cooperating portion 117 or be spaced apart from the cooperating portion 117 when the second interference portion 12132 corresponds to the cooperating portion 117 in the longitudinal direction, and at this time, the bottom wall 1211 can abut against the guide portion 1A to limit the distance of the cover 121 moving relative to the main body assembly 11 in the first direction x.

[0130] Referring to FIG. 6, at least part of the operation portion 125 is arranged on the outside of the annular side wall 1212, or at least part of the operation portion 125 is a part of the annular side wall 1212. For example, the operation portion 125 can be a non-slip pattern arranged on the outside of the annular side wall 1212, or can be a toothed disc arranged on the outside of the annular side wall 1212. For example, the cover 121 can be driven to rotate by operating the outside of the annular side wall 1212; or the cover 121 can be moved in the longitudinal direction by holding the outside of the annular side wall 1212.

[0131] At least part of the operation portion 125 can be a constituent part of the bottom wall 1211. For example, the cover member 121 can be driven to move in the reverse direction of the first direction x by pressing the bottom wall 1211.

[0132] In some embodiments, referring to FIGS. 4, 5 and 7-11, the main body assembly 11 can include a housing 113 in which the storage cavity is located. The main body assembly 11 can further include a sealing cover 114 connected to the housing 113 and sealing the storage cavity to prevent leakage of the aerosol generating substrate out of the storage cavity. The flow guide hole 112 can be formed in the sealing cover 114.

[0133] Specifically, the sealing cover 114 can include a base 1141 and a sealing member 1142 at least part of which is disposed between the housing 113 and the base 1141 to provide sealing therebetween. The convex column 118 having the flow guide hole 112 therein can be integrally injection molded with the base 1141.

[0134] The support member 122 or the flexible plug 123 can support the base 1141 when the cover member 121 is in the locked state, and of course, the support member 122 or the flexible plug 123 can be spaced apart from the base 1141 in the longitudinal direction. Since the support member 122 or the flexible plug 123 can float to support the main body assembly 11, the support member 122 or the flexible plug 123 can continue to support the base 1141 when the cover member 121 is in the unlocked state, and of course, the support member 122 or the flexible plug 123 can continue to be spaced apart from the base 1141 in the longitudinal direction.

[0135] The sealing cover 114 can be located inside the housing 113 and thus be shielded by the housing 113, and the support member 122 or the flexible plug 123 can float to support the main body assembly 11 by floating to support the housing 113. The support member 122 or the flexible plug 123 can support the housing 113 when the cover member 121 is in the locked state, and continue to support the housing 113 when the cover member 121 is in the unlocked state.

[0136] In some embodiments, referring to FIGS. 4, 5 and 7-11, the main body assembly 11 can further include a mouthpiece 115 and an air guide tube 116 in fluid communication with the mouthpiece 115. The mouthpiece 115 can be held by the user's mouth. One end of the air guide tube 116 is connected to the mouthpiece 115, and the air guide tube 116 can be integrally injection molded with the mouthpiece 115. The other end of the air guide tube 116 can pass through the sealing cover 114 to be connected to and in fluid communication with the atomizing assembly 2 when the aerosol substrate reservoir 1 is engaged with the atomizing assembly 2.

[0137] Part of the air guide tube 116 can be located in the storage cavity, so that the connection between the air guide tube 116 and the sealing cover 114 is a sealed connection to prevent leakage of the aerosol generating substrate along the wall of the air guide tube 116. Specifically, the sealing member 1142 can be arranged around the air guide tube 116 and in interference fit with the air guide tube 116.

[0138] When the cover 121 is in the locked state, the end of the air guide tube 116 can be spaced apart from the flexible plug 123, of course, can abut the flexible plug 123, or can be inserted into the flexible plug 123.

[0139] The mouthpiece 115 and the shell 113 can be integrally injection molded.

[0140] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification, and further, those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
