Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and particularly relates to an aerosol matrix reservoir and a device including the aerosol matrix reservoir. Background Art

[0002] An aerosol generating device is a device capable of atomizing an aerosol generating preparation to form an aerosol. The aerosol generating device is independently produced from an article containing the aerosol generating preparation. Thus, before use, the aerosol generating device and the article containing the aerosol generating preparation are stored separately, and when in use, the aerosol generating device is engaged with the article containing the aerosol generating preparation.

[0003] In some exemplary prior arts, the article of the aerosol generating preparation further includes a diversion hole for guiding out the aerosol generating preparation and a soft plug for blocking the diversion hole. A part of the soft plug is exposed outside to allow a user to pull out the soft plug before the article is engaged with the aerosol generating device.

[0004] However, when the article is obtained by an undesired group of people such as children, the soft plug can be easily pulled out from the diversion hole through simple operation, resulting in leakage of the aerosol generating preparation. Summary of the Utility Model

[0022] As an example, the main body component includes a second interference portion;

[0023] The second component includes a second mating portion, the second mating portion includes a second rotation guiding edge, and the second interference portion is configured to rotate along the second rotation guiding edge during at least a part of the stroke of the second component rotating relative to the main body component, and interfere with the second mating portion in the first direction.

[0024] As an example, one of the first component and the second component is provided with a first limiting wall and a second limiting wall, and the other is provided with a limiting block, and the limiting block is configured to rotate between the first limiting wall and the second limiting wall during the relative rotation of the first component and the second component, so that the relative rotation angle of the first component and the second component is less than 360°.

[0025] As an example, the first component further includes a first side wall, and the limiting block includes a protrusion provided on the first side wall;

[0026] The second component further includes a second side wall, and a strip-shaped first limiting groove is formed on the second side wall, and the protrusion is rotatably arranged in the first limiting groove, and the first limiting wall and the second limiting wall respectively define partial boundaries of the first limiting groove.

[0027] As an example, the limiting block includes a first mating portion, and the first mating portion is used for interference mating with the main body component in the first direction;

[0028] The second component further includes a second side wall, and a second limiting groove is formed on the second side wall, and the first mating portion is rotatably arranged in the second limiting groove, and the first limiting wall and the second limiting wall respectively define partial boundaries of the second limiting groove.

[0029] As an example, there are at least two first mating portions in the second limiting groove, and a first assembly channel is arranged between adjacent two first mating portions, and the first assembly channel is used to guide the removal of the first component from the main body component.

[0030] As an example, the first component has a first positioning portion, and the second component includes a second positioning portion;

[0031] During the rotation of the first component relative to the second component, at least one of the first positioning portions interferes with the second positioning portion to prompt the first component to enter the locking position or the unlocking position.

[0032] As an example, the main body assembly includes a nozzle, a housing, an air duct, and a sealing cover;

[0033] The storage cavity is located in the housing and is disposed between the nozzle and the sealing cover. The sealing cover is connected to the housing and seals the storage cavity. One end of the air duct is connected to the nozzle, and the other end passes through the sealing cover.

The blocking assembly includes a first member that can rotate relative to the main body assembly; wherein, the first member is configured to be able to provide an operation for the user to rotate between a locking position and an unlocking position. When the first member is in the unlocking position, the blocking assembly can be removed from the main body assembly along a first direction to expose the diversion hole; and when the first member rotates to the locking position, it interferes with the main body assembly in the first direction, thereby preventing the blocking assembly from being removed from the main body assembly. Thus, at least the first member needs to be rotated relative to the main body assembly to an appropriate position before the locking connection between the blocking assembly and the main body assembly can be unlocked, and then the blocking assembly can be removed from the main body assembly, thereby exposing the diversion hole. Therefore, it can effectively prevent an undesired user group such as a child from intentionally or unintentionally removing the blocking assembly from the main body assembly.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0056] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element, or there may be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0057] Please refer to Figures 1 - 10 , some embodiments of the present application provide an aerosol matrix reservoir 1, which is a container capable of storing an aerosol - generating matrix. The aerosol matrix reservoir 1 can be engaged with an atomization assembly 2 to form an aerosol - generating device, and after being engaged, it can provide an aerosol - generating matrix for the atomization assembly 2 in the aerosol - generating device for the atomization assembly 2 to atomize and generate an aerosol.

[0058] Please refer to Figure 2 and Figure 6 , the aerosol matrix reservoir 1 includes a main body assembly 11, and the main body assembly 11 has a storage cavity 111 for accommodating the aerosol - generating matrix. The aerosol - generating matrix can be stored in the storage cavity 111 by means of injection or filling, etc.

[0059] In some embodiments, the aerosol - generating matrix includes a liquid matrix. The liquid matrix may include a liquid containing a tobacco - containing substance with a volatile tobacco flavor component, and may also be a liquid containing a non - tobacco substance. The liquid matrix may include water, a medicinal liquid, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture, etc. The fragrance may include areca extract, menthol, peppermint, spearmint oil, various fruit fragrance components, etc., but is not limited thereto. The flavoring agent includes components that can provide various scents or flavors to the user. The vitamin mixture may 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 the different properties of the liquid matrix, the aerosol matrix reservoir can be used in different fields, such as medical, electronic aerosol atomization, etc.

[0060] In some embodiments, the main body assembly 11 may further include a liquid - absorbing cotton 112. The liquid - absorbing cotton 112 is disposed in the storage cavity 111. The liquid - absorbing cotton 112 is used for adsorbing the liquid matrix, which helps to confine the liquid matrix in the storage cavity 111 within the liquid - absorbing cotton 112, thereby preventing the liquid matrix from leaking from the storage cavity 111. It should be noted that the liquid - absorbing cotton 112 is optional rather than essential.

[0061] Please refer to Figure 4 and Figure 7, a diversion hole 117 for draining the aerosol - generating matrix out of the storage cavity 111 is provided on the main body component 11.

[0062] In some embodiments, the atomization component 2 has a chamber for receiving and storing the aerosol - generating matrix. Therefore, when the atomization component 2 is not engaged with the aerosol matrix reservoir 1, no aerosol can be generated. After the atomization component 2 is engaged with the aerosol matrix reservoir 1, the atomization component 2 is connected to the diversion hole 117, and the aerosol - generating matrix accommodated in the main body component 11 can flow into the atomization component 2 and be atomized by the atomization component 2.

[0063] The atomization component 2 further includes an atomization core for atomizing the aerosol - generating matrix. The atomization core is in fluid communication with the chamber, so that the atomization core can transfer and atomize the aerosol - generating matrix in the chamber. After the atomization component is engaged with the aerosol matrix reservoir 1, the atomization component 2 is connected to the diversion hole 117, and the aerosol - generating matrix in the aerosol matrix reservoir 1 can flow into the chamber of the aerosol - generating device, thereby replenishing the aerosol - generating matrix in the chamber.

[0064] As an exemplary embodiment, the atomization core may include a liquid - absorbing element and a heating element, and the heating element is disposed on the liquid - absorbing element. The liquid - absorbing element may be a porous body for guiding the liquid matrix into the atomization range of the heating element. The heating element is used to heat and atomize the aerosol matrix to generate aerosol. The porous body may be a fiber, such as cotton fiber, polypropylene fiber, polyester fiber or nylon fiber, etc. The porous body may be porous ceramic or porous metal, and the present application does not limit the structure and composition of the porous body.

[0065] As an exemplary embodiment, the atomization core may include an ultrasonic element capable of vibrating at high frequency under ultrasonic drive, and the atomization core uses ultrasonic vibration to atomize the liquid matrix to form aerosol. Of course, the atomization core may also include other elements capable of atomizing the liquid matrix to form aerosol.

[0066] The above - mentioned aerosol - generating device may further include a power supply component 3, and the power supply component 3 can be electrically connected to the atomization component 2 to provide power for atomizing the aerosol - generating matrix by the atomization component 2. The power supply component 3 may include any suitable battery, for example, it may include a rechargeable battery, and of course, it may also include a disposable battery.

[0067] Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the aerosol matrix reservoir 1 further includes a blocking component 12. The blocking component 12 is used to block the diversion hole 117 of the main body component 11 when the aerosol matrix reservoir 1 is stored separately, so as to prevent the diversion hole 117 from being open and causing the aerosol - generating matrix in the storage cavity 111 to leak through the diversion hole 117.

[0068] As an example of the blocking component 12, the blocking component 12 is connected to the main body component 11 to keep the diversion hole 117 blocked through the connection. The blocking component 12 includes a first member 121, and the first member 121 can rotate relative to the main body component 11. Specifically, the first member 121 can rotate between a latched position and an unlocked position under the operation of the user. When the first member 121 is in the unlocked position, the blocking component 12 can be removed from the main body component 12 along the first direction, and then the diversion hole 117 can be exposed; and when the first member 121 rotates to the latched position, it interferes with the main body component in the first direction, thereby preventing the blocking component 12 from being removed from the main body component 11.

[0069] Thus, at least the first member 121 needs to be rotated relative to the main body component 11 to an appropriate position before the locking connection between the blocking component 12 and the main body component 11 can be unlocked, and only then can the blocking component 12 be removed from the main body component 11, and then the diversion hole 117 can be exposed.

[0070] It should be noted that when the main body component 11 and the blocking component 12 are in a locked connection, the blocking component 12 is prevented from being removed from the main body component 11. Therefore, when the main body component 11 and the blocking component 12 are in a locked connection, the blocking component 12 can keep the diversion hole 117 blocked. Among them, when the first member 121 interferes with the main body component 11 in the first direction, it is one of the means for the main body component 11 and the blocking component 12 to achieve a locked connection. Other components in the blocking component 12 can also interfere with the main body component 11 in the first direction, thereby preventing the blocking component 12 from being removed from the main body component 11.

[0071] In some embodiments, the diversion hole 117 in the initial state is blocked. After the blocking component 12 is removed from the main body component 11, other operations are still required to open the diversion hole 117 so that the aerosol-forming substrate in the storage cavity 111 can flow out through the diversion hole 117. For example, the diversion hole 117 has a sealing film that can be punctured. Before the sealing film is punctured, the sealing film can isolate the storage cavity 111 from the outside, so that the aerosol-forming substrate cannot flow out through the diversion hole 117. Among them, during the process of engaging the aerosol substrate reservoir 1 with the atomizing component 2, the sealing film can be punctured by the atomizing component 2. Thus, after the aerosol substrate reservoir 1 is engaged with the atomizing component 2, the aerosol-forming substrate in the aerosol substrate reservoir 1 can be atomized by the atomizing component 2 through the connection between the atomizing component 2 and the diversion hole 117. Or for example, the main body component 11 further includes a removable seal such as a silica gel plug. At least a part of the silica gel plug surrounds the diversion hole 117 or at least a part extends into the diversion hole 117, thereby blocking the diversion hole 117. In use, before the aerosol substrate reservoir 1 is engaged with the diversion hole 117, the silica gel plug needs to be pulled out first.

[0072] Therefore, when the blocking component 12 is connected to the main body component 11, the blocking component 12 prevents the diversion hole 117 from being accidentally punctured or prevents the silica gel plug from being exposed and pulled out by blocking the diversion hole 117.

[0073] In some embodiments, reference may be made to Figure 10 , the diversion hole 117 in the initial state is open. After the blocking component 12 is removed from the main body component 11, the aerosol-forming substrate in the storage cavity 111 can flow out through the diversion hole 117. Based on this, the blocking component 12 may further include a seal 123. The seal 123 can seal the diversion hole 117 when the blocking component 12 is locked to the main body component 11, thereby preventing the aerosol-forming substrate in the storage cavity 111 from leaking.

[0074] The seal 123 can be made of silica gel. When the blocking component 12 is locked to the main body component 11, at least a part of the seal 123 can block the diversion hole 117. The seal 123 or the main body component 11 may have an annular rib. When the blocking component 12 is locked to the main body component 11, the blocking component 12 and the main body component 11 are elastically abutted against each other through the annular rib, and a sealing cavity surrounded by the annular rib is formed between the blocking component 12 and the main body component 11. The diversion hole 117 is arranged corresponding to the sealing cavity.

[0075] In such as Figure 4 and Figure 7In the illustrated embodiment, a receiving cavity 1231 is provided on the seal 123. The main body assembly 11 includes a convex post 118 which is hollow inside, and the interior of the convex post 118 is in fluid communication with the storage cavity 111. A diversion hole 117 is formed in the wall of the convex post 118. When the locking assembly 12 is connected and locked to the main body assembly 11, at least a part of the convex post 118 is located in the receiving cavity 1231 and is in interference fit with the seal 123, so that the seal 123 mainly blocks the diversion hole 117 outside the diversion hole 117. For example, if the diversion hole 117 is formed in the side wall of the convex post 118, the diversion hole 117 is located in the receiving cavity 1231 and is surrounded by the seal 123. Since the convex post 118 is in interference fit with the diversion hole 117, the seal 123 can block the diversion hole 117 on the outer side of the side of the diversion hole 117. For example, if the diversion hole 117 is formed in the end wall of the convex post 118, the receiving cavity 1231 is a blind hole, the diversion hole 117 is located in the receiving cavity 123 and is arranged towards the bottom of the receiving cavity 123. Since the convex post 118 is in interference fit with the diversion hole 117, the seal 123 can prevent the diversion hole 117 from communicating with the outside.

[0076] Preferably, the convex post 118 extends in the first direction to prevent the convex post 118 from hindering the removal of the locking assembly 12 from the main body assembly 11.

[0077] The seal 123 is configured to be rotatable relative to the first member 121. When the first member 121 rotates relative to the main body assembly 11, the seal 123 can rotate relative to the first member 121, and the seal 123 can remain relatively stationary with respect to the convex post 118. Further, during the rotation of the first member 121 relative to the main body assembly 11, the seal 123 can remain relatively stationary with respect to the main body assembly 11.

[0078] Based on this, in some embodiments, the receiving cavity 1231 is located at a position deviating from the axial center of the seal 123, that is, the central axis of the receiving cavity 1231 is offset from the central axis of the seal 123. Thus, after at least a part of the convex post 118 is embedded in the receiving cavity 1231, when the first member 121 rotates relative to the main body assembly 11, the convex post 118 can drive the seal 123 to rotate relative to the first member 121 by interfering with the receiving cavity 1231 in the second direction or the transverse direction. In this embodiment, there can be one and only one convex post 118, or there can also be multiple convex posts.

[0079] In some embodiments, there may be multiple protruding posts 118, and each protruding post 118 can be embedded in a receiving cavity 1231. After at least a part of the protruding post 118 is embedded in the receiving cavity 1231, when the first member 121 rotates relative to the main body assembly 11, the protruding post 118 can drive the seal 123 to rotate relative to the first member 121 by interference fit with the receiving cavity 1231. In this embodiment, the flow guiding holes 117 may not be provided in some of the protruding posts 118, and of course, the flow guiding holes 117 may be provided in all of the protruding posts 118.

[0080] In some embodiments, during the rotation of the first member 121 relative to the main body assembly 11, the seal 123 is configured to be able to keep the flow guiding hole 171 sealed, so that during the unlocking process of the locking connection between the main body assembly 11 and the locking assembly 12, the seal 123 can prevent the aerosol generating substrate in the storage cavity 111 from leaking through the flow guiding hole 171.

[0081] In some embodiments, reference may be made to Figure 4 and Figure 7 that the locking assembly 12 includes a bottom wall 1211 for supporting the seal 123. The bottom wall 1211 may extend substantially in a second direction perpendicular to the first direction. The bottom wall 1211 may be substantially sheet-like. The bottom wall 1211 may be a component part of the first member 121. When the locking assembly 12 is locked to the main body assembly 11, the bottom wall 1211 can support the main body assembly 11, such as supporting the housing 113 of the main body assembly 11.

[0082] In some embodiments, reference may be made to Figure 3 that the main body assembly 11 includes a first interference portion 1191, the first member 121 includes a first mating portion 1212, the first mating portion 1212 includes a first rotation guiding edge 1A, and the first interference portion 1191 is configured to rotate along the first rotation guiding edge 1A during at least a part of the stroke of the rotation of the first member 121 relative to the main body assembly 11 and interfere with the first mating portion 1212 in the first direction.

[0083] The first rotation guide edge 1A can extend arcuately on a plane perpendicular to the first direction, so that when the first interference portion 1191 rotates relative to the first member 121 along the first rotation guide edge 1A, it can prevent the first interference portion 1191 from displacing or fluctuating in the first direction. And when the blocking assembly 12 includes a seal 123, it can also prevent the distance between the seal 123 and the diversion hole 117 from increasing in the first direction and prevent the outlet 1171 of the diversion hole 117 from being disengaged from the seal of the seal 123 during the rotation of the first member 121 relative to the main body assembly 11, so that the seal 123 maintains sealing or blocks the diversion hole 117. In this way, when a child intentionally or unintentionally drives the first member 121 to rotate relative to the main body assembly 11, the aerosol generating matrix in the main body assembly 11 can be prevented from leaking through the diversion hole 117.

[0084] In some embodiments, reference may be made to Figure 3 and Figure 5 , the first member 121 further includes a first side wall 1213 and a stop wall 1214 spaced apart from the first side wall 1213, and the first engaging portion 1212 is provided on the first side wall 1213; the first interference portion 1191 is configured to be rotatable relative to the first member 121 to a latched position.

[0085] Wherein, during at least part of the stroke when the first interference portion 1191 rotates relative to the first member 121 to the latched position, the first interference portion 1191 can rotate relative to the first member 121 along the first rotation guide edge 1A, so that the blocking assembly 12 and the main body assembly 11 remain in a locked connection. The first rotation guide edge 1A can guide the first interference portion 1191 so that the first interference portion 1191 can rotate relative to the first member 121 to the latched position. When the first interference portion 1191 is in the latched position, the first interference portion 1191 can still interfere and cooperate with the first rotation guide edge 1A in the first direction.

[0086] Reference may be made to Figures 2 - 5When the first interference portion 1191 is in the locking position, the first interference portion 1191 is located between the stop wall 1214 and the first side wall 1213. The stop wall 1214 and the first side wall 1213 may be spaced apart from each other in a second direction perpendicular to the first direction. When the first interference portion 1191 is in the locking position, the first interference portion 1191 is disposed adjacent to the stop wall 1214 in the second direction, and the adjacent arrangement includes the first interference portion 1191 contacting the stop wall 1214 in the second direction or having a small gap, so as to prevent the first interference portion 1191 from deforming toward the side away from the first side wall 1213 in the second direction, so that the first interference portion 1191 and the first rotation guide 1A maintain interference fit in the first direction, and can prevent the blocking component 12 from being separated from the main body component 11 in the first direction under the action of brute force in the first direction when the first interference portion 1191 is in the locking position. Therefore, if the correct unlocking method is not followed, the blocking component 12 cannot be removed from the main body component 11.

[0087] In some embodiments, reference may be made to Figure 3 and Figure 5 The first member 121 further includes a retaining wall 1215 spaced apart from the first side wall 1213 in the second direction, the retaining wall 1215 is used to abut against the side of the seal 123, so that the seal 123 can be retained in the blocking assembly 12. In some examples, the first member 121 may have at least two retaining walls 1215 spaced apart from each other, the two retaining walls 1215 may be disposed opposite to each other, and the seal 123 may be located between the two retaining walls 1215. The seal 123 may rotate between the plurality of retaining walls 1215.

[0088] The retaining wall 1215 may be connected to the stop wall 1214. The stop wall 1214 may be disposed on the bottom wall 1211 and may extend along the first direction. The retaining wall 1215 may be disposed on the bottom wall 1211 and may extend along the first direction, the stop wall 1214 may be disposed substantially perpendicular to the retaining wall 1215, and the thickness of the stop wall 1214 may be substantially the same as the thickness of the retaining wall 1215. The stop wall 1214 may be integrally injection molded with the bottom wall 1211, the retaining wall 1215 may be integrally injection molded with the bottom wall 1211, and the first side wall 1213 may be integrally injection molded with the bottom wall 1211.

[0089] In some embodiments, reference may be made to Figures 6 - 9As shown, the locking assembly 12 further includes a second member 122 rotatably connected to the first member 121; the first member 121 includes a first operation portion 1216, and the first operation portion 1216 is configured to be operable by a user and to drive the first member 121 to rotate relative to the main body assembly 11 based on this operation; the second member 122 includes a second operation portion 1221, and the second operation portion 1221 is configured to be operable by a user and to drive the second member 122 to rotate relative to the main body assembly 11 based on this operation.

[0090] When the locking assembly 12 is connected to the main body assembly 11, if the first member 121 is rotated relative to the main body assembly 11 by operating the first operation portion 1216 so that the first member 121 interferes and cooperates with the main body assembly 11 in the first direction, and the locking assembly 12 is locked to the main body assembly 11, then if the second member 122 is rotated relative to the main body assembly 11 by driving the second operation portion 1221, it is impossible to unlock the locking connection between the locking assembly 12 and the main body assembly 11 anyway. The correct unlocking method can be to rotate the first member 121 relative to the main body assembly 11 in the reverse direction again through the first operation portion 1216 to return to the initial position, so that the interference fit between the first member 121 and the main body assembly 11 in the first direction is released, and then the locking assembly 12 is removed from the main body assembly 11 along the first direction. Therefore, providing the second member 122 with the second operation portion 1221 can increase the interference for unlocking the locking connection between the locking assembly 12 and the main body assembly 11.

[0091] In some embodiments, reference may be made to Figure 8 such that the locking assembly 12 is configured to be locked to the main body assembly 11 when the second member 122 rotates to interfere and cooperate with the main body assembly 11 in the first direction.

[0092] Therefore, the interference fit between the second member 122 and the main body assembly 11 in the first direction can be one of the means to achieve the locking connection between the locking assembly 12 and the main body assembly 11. When the first member 121 interferes and cooperates with the main body assembly 11 in the first direction, or when the second member 122 interferes and cooperates with the main body assembly 11 in the first direction, or when both the first member 121 and the second member 122 interfere and cooperate with the main body assembly 11 in the first direction, the locking assembly 12 and the main body assembly 11 can be locked together and cannot be separated from each other in the first direction.

[0093] For example, when combining the locking component 12 with the main body component 11, if the second component 122 is rotated relative to the main body component 11 by operating the second operation part 1221 until the second component 122 interferes and cooperates with the main body component 11 in the first direction, so that the locking component 12 and the main body component 11 are locked and connected; then the correct unlocking method can be to rotate the second component 122 relative to the main body component 11 in the reverse direction again through the second operation part 1221 until it returns to the initial position, so that the interference fit between the second component 122 and the main body component 11 in the first direction is released, and then the locking component 12 is removed from the main body component 11 in the first direction.

[0094] Or for example, when combining the locking component 12 with the main body component 11, if the first component 121 is rotated relative to the main body component 11 by operating the first operation part 1216 until the first component 121 interferes and cooperates with the main body component 11 in the first direction, and at the same time the second component 122 is rotated relative to the main body component 11 by operating the second operation part 1221 until the second component 122 interferes and cooperates with the main body component 11 in the first direction, so that the locking component 12 and the main body component 11 are locked and connected. Then the correct unlocking method can be to rotate the first component 121 relative to the main body component 11 in the reverse direction again through the first operation part 1216 until it returns to the initial position, so that the interference fit between the first component 121 and the main body component 11 in the first direction is released, and the second component 122 is rotated relative to the main body component 11 in the reverse direction through the second operation part 1221 until it returns to the initial position, so that the interference fit between the second component 122 and the main body component 11 in the first direction is released, and then the locking component 12 is removed from the main body component 11 in the first direction.

[0095] In some embodiments, reference may be made to Figure 8 and Figure 9 , the main body component 11 includes a second interference part 1192; the second component 122 includes a second cooperation part 1222, the second cooperation part 1222 includes a second rotation guiding edge 2A, and the second interference part 1192 is configured to rotate along the second rotation guiding edge 2A during at least part of the stroke of the second component 122 rotating relative to the main body component 11, and interfere and cooperate with the second cooperation part 1222 in the first direction.

[0096] The second rotation guide 2A can extend arcuately on a plane perpendicular to the first direction. Thereby, when the second interference portion 1192 rotates relative to the second member 122 along the second rotation guide 2A, it is possible to prevent the second interference portion 1192 from displacing or fluctuating in the first direction. And when the blocking assembly 12 includes a seal 123, it is also possible thereby to prevent the distance between the seal 123 and the diversion hole 117 from increasing in the first direction during the relative rotation of the second member 122 with respect to the main body assembly 11, and to prevent the outlet 1171 of the diversion hole 117 from disengaging from the seal of the seal 123, so that the seal 123 maintains the seal or blocks the diversion hole 117. In this way, when a child intentionally or unintentionally drives the second member 122 to rotate relative to the main body assembly 11, the aerosol generating substrate in the main body assembly 112 can be prevented from leaking through the diversion hole 117.

[0097] In some embodiments, the first member 121 and the second member 122 are configured such that the relative rotation angle between the two is less than 360°, so as to reduce the difficulty of unlocking the locking connection between the blocking assembly 12 and the main body assembly 11.

[0098] For example, with reference to Figure 8 and Figure 9 , a first limiting wall 3A1, 4A1 and a second limiting wall 3A2, 4A2 can be provided on one of the first member 121 and the second member 122, and a limiting block can be provided on the other. The limiting block is configured to rotate between the first limiting wall 3A1, 4A1 and the second limiting wall 3A2, 4A2 during the relative rotation of the first member 121 and the second member 122, so that the relative rotation angle between the first member 121 and the second member 122 is less than 360°.

[0099] In some embodiments, with reference to Figure 8 and Figure 9 , the first member 121 further includes a first side wall 1213, and the limiting block includes a protrusion 1217 provided on the first side wall 1213; the second member 122 further includes a second side wall 1223, and a first limiting groove 1224 is formed in the second side wall 1223. The protrusion 1217 is rotatably provided in the first limiting groove 1224, and the first limiting wall 3A1 and the second limiting wall 3A2 respectively define partial boundaries of the first limiting groove 1224.

[0100] The first limiting wall 3A1 and the second limiting wall 3A2 can be respectively two circumferentially opposite groove walls of the first limiting groove 1224. The first limiting groove 1224 can be a strip-shaped groove, so the first limiting groove 1224 has two opposite groove walls in the first direction. The two opposite groove walls of the first limiting groove 1224 in the first direction can limit the swaying amplitude of the first component 121 relative to the second component 122 in the first direction by interference fit with the bump 1217, or can prevent the first component 121 from swaying relative to the second component 122 in the first direction, or can prevent the first component 121 and the second component 122 from separating from each other in the first direction.

[0101] The first side wall 1213 and the second side wall 1223 can be slidably connected, and when the first component 121 and the second component 122 rotate relative to each other, the first side wall 1213 can rotate closely against the second side wall 1223.

[0102] In some embodiments, reference may be made to Figure 8 and Figure 9 , the limiting block includes a first mating portion 1212, and the first mating portion 1212 is used for interference fit with the main body assembly 11 in the first direction; the second component 122 further includes a second side wall 1223, and a second limiting groove 1225 is formed on the second side wall 1223. The first mating portion 1212 is rotatably disposed in the second limiting groove 1225, and the first limiting wall 4A1 and the second limiting wall 4A2 respectively define partial boundaries of the second limiting groove 1225.

[0103] Therefore, the first mating portion 1212 can both provide the first rotation guide edge 1A for interference fit with the first interference portion 1911 in the first direction, and can cooperate with the first limiting wall 4A1 or the second limiting wall 4A2 during the relative rotation of the first component 121 and the second component 122, so that the relative rotation angle between the first component 121 and the second component 122 is less than 360°.

[0104] Further, reference may be made to Figure 8 and Figure 9 , at least two first mating portions 1212 can be provided in one second limiting groove 1225, and a first assembly channel 1218 is provided between two adjacent first mating portions 1212. The first assembly channel 1218 is used to guide the removal of the first component 121 from the main body assembly 11.

[0105] The first assembly channel 1218 may extend generally along a first direction. At least a portion of the first side wall 1213 is disposed between two adjacent first mating portions 1212, connecting the two adjacent first mating portions 1212 and defining a partial boundary of the first assembly channel 1218. During at least a portion of the travel of the first member 121 removed from the main assembly 11, the first interference portion 1191 may move along the first assembly channel 1218.

[0106] The first assembly channel 1218 and the first mating portion 1212 may be located inside the second side wall 1223, and the first mating portion 1212 may slide along the inner surface of the second side wall 1223.

[0107] In some embodiments, reference may be made to Figure 8 and Figure 9 , the first member 121 has a first positioning portion 1219, and the second member 122 includes a second positioning portion 1226; the first member 121 is configured to be rotatable relative to the second member 122 between a first position and a second position, and when the first member 121 is in the first position and the second position relative to the second member 122, at least one first positioning portion 1219 interferes and mates with the second positioning portion 1226. One of the first position and the second position may be a locking position, and the other may be an unlocking position.

[0108] The first position and the second position may be located between a set of first limiting walls 3A1, 4A1 and second limiting walls 3A2, 4A2. For example, when the first mating portion 1212 abuts against the first limiting wall 4A1, at least one first positioning portion 1219 may interfere and mate with the second positioning portion 1226; when the first mating portion 1212 abuts against the second limiting wall 4A2, at least one first positioning portion 1219 may interfere and mate with the second positioning portion 1226.

[0109] The first position may be disposed close to the first limiting walls 3A1, 4A1, and the second position may be disposed close to the second limiting walls 3A2, 4A2. For example, when the first member 121 is in the first position relative to the second member 122, the first mating portion 1212 can contact the first limiting wall 4A1, and of course, it can also be spaced apart from the first limiting wall 4A1; when the first member 121 is in the second position relative to the second member 122, the first mating portion 121 can contact the second limiting wall 4A2, and of course, it can also be spaced apart from the second limiting wall 4A2.

[0110] In some embodiments, when the first positioning portion 1219 and the second positioning portion 1226 are in interference fit, the blocking assembly 12 will generate a prompt signal. The prompt signal can be a sound emitted when the first positioning portion 1219 and the second positioning portion 1226 are in interference fit. The prompt signal can be a vibration sensation generated when the first positioning portion 1219 and the second positioning portion 1226 are in interference fit. The prompt signal can be used to prompt the first member 121 to enter the locking position or the unlocking position.

[0111] In some embodiments, when the first positioning portion 1219 and the second positioning portion 1226 are in interference fit, if it is necessary to relatively rotate the first member 121 and the second member 122, the first operating portion 1216 and the second operating portion 1221 need to be operated simultaneously. If only the first operating portion 1216 or only the second operating portion 1221 is operated, the first member 121 and the second member 122 may rotate relative to the main body assembly 11 simultaneously.

[0112] In some embodiments, reference may be made to Figure 8 and Figure 9 , the second positioning portion 1226 is disposed in the second limiting groove 1225. There may be two second positioning portions 1226 in one second limiting groove 1225. One second positioning portion 1226 is disposed close to the first limiting wall 4A1, and the other second positioning portion 1226 is disposed close to the second limiting wall 4A2. The first positioning portion 1219 corresponding to one second limiting groove 1225 may have one; when the first member 121 is in the first position relative to the second member 122, the first positioning portion 1219 and the second positioning portion 1226 disposed close to the first limiting wall 4A1 are in interference fit; when the first member 121 is in the second position relative to the second member 122, the first positioning portion 1219 and the second positioning portion 1226 disposed close to the second limiting wall 4A2 are in interference fit.

[0113] In some embodiments, reference may be made to Figure 8 and Figure 9 , there are two second limiting grooves 1225, and the two second limiting grooves 1225 may be disposed opposite to each other. At least one second limiting groove 1225 is provided with two first engaging portions 1212 disposed at intervals.

[0114] Furthermore, reference may be made to Figure 8 and Figure 9 , at least one first limiting groove 1224 is disposed between the two second limiting grooves 1225.

[0115] In some embodiments, reference may be made to Figure 8 and Figure 9 , there are two first limiting grooves 1224, and the two first limiting grooves 1224 are disposed opposite to each other. A bump 1217 is disposed in each first limiting groove 1224.

[0116] Further, reference may be made to Figure 8 and Figure 9 , and at least one second limiting groove 1225 is provided between the two first limiting grooves 1224.

[0117] In some embodiments, reference may be made to Figure 8 and Figure 9 , a second assembly channel 1227 is provided on the second side wall 1223, and the second assembly channel 1227 is used to guide the second component 122 to be removed from the main body assembly 11. The second assembly channel 1227 may extend substantially along the first direction. The side edge of the second engaging portion 1222 may define at least a part of the boundary of the second assembly channel 1227. During at least a part of the stroke of the second component 122 being removed from the main body assembly 11, the second interference portion 1192 may move along the second assembly channel 1227.

[0118] In some embodiments, reference may be made to Figure 4 , Figure 7 and Figure 10 , the main body assembly 11 includes a housing 113, and a storage cavity 111 is located in the housing 113. The main body assembly 11 may further include a sealing cover 114, and the sealing cover 114 is connected to the housing 1113 and seals the storage cavity 111 to prevent the aerosol generating matrix from leaking out of the storage cavity 111. Among them, a diversion hole 117 may be opened on the sealing cover 114.

[0119] Specifically, the sealing cover 114 may include a base 1141 and a flexible member 1142, and at least a part of the flexible member 1142 is disposed between the housing 113 and the base 1141 to provide a seal between the housing 113 and the base 1141. A boss 118 having a diversion hole 117 inside may be integrally injection molded with the base 1141.

[0120] When the locking assembly 12 is locked to the main body assembly 11, the stop wall 1214 may support the base 1141. Of course, the stop wall 1214 may also be spaced apart from the base 1141 in the first direction. When the locking assembly 12 is locked to the main body assembly 11, the retaining wall 1215 may support the base 1141. Of course, the retaining wall 1215 may also be spaced apart from the base 1141 in the first direction.

[0121] The sealing cover 114 may be located inside the housing 113 and thus be blocked by the housing 113. When the locking assembly 12 is locked to the main body assembly 11, the sealing cover 114 may be spaced apart from the bottom wall 1211 in the first direction.

[0122] In some embodiments, reference may be made to Figure 4 , Figure 7 and Figure 10, the main body assembly 11 further includes a mouthpiece 115 and an air duct 116 that is in fluid communication with the mouthpiece 115. The mouthpiece 115 can be provided for a user to hold in the mouth. One end of the air duct 116 is connected to the mouthpiece 115, and the air duct 116 can be integrally injection molded with the mouthpiece 115. The other end of the air duct 116 can pass through the sealing cap 114 so as to be in fluid communication with the atomizing assembly 2 when the aerosol matrix reservoir 1 is engaged with the atomizing assembly 2.

[0123] A part of the air duct 116 is located in the storage cavity 111, so that the connection between the air duct 116 and the sealing cap 114 is a sealed connection to prevent the aerosol generating matrix from leaking along the wall of the air duct 116. Specifically, the flexible member 1142 is disposed around the air duct 116 and has an interference fit with the air duct 116.

[0124] When the locking assembly 12 is locked to the main body assembly 11, the end of the air duct 116 can be spaced apart from the seal 123, or can also abut against the seal 123.

[0125] In some examples, the mouthpiece 115 and the housing 113 can be integrally injection molded.

[0126] It should be noted that the description and drawings of this application give preferred embodiments of this application, but are not limited to the embodiments described in this specification. Further, for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this application.
