[0049] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0050] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0051] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0052] Currently, most aerosol generating devices require users to use cotton swabs or other cleaning tools to clean the residue deposited or remaining in the internal cavities of the device. This is not only cumbersome and inconvenient, but also often requires users to carry cotton swabs or other cleaning tools with them. In addition, incomplete cleaning of residue can easily lead to problems such as deterioration of the aerosol's taste and quality, and damage to internal components of the device.

[0053] The aerosol generating device provided in this application allows for the real-time collection and storage of residues inside the device by inserting a collection container inside the device and utilizing the sealed connection between the collection container and the heating component. Once the residues collected in the collection container have accumulated to a certain amount, the collection container can be removed, allowing for the cleaning of the residues collected in the collection container from the outside of the device. This not only prevents residues from accumulating inside the device but also makes it convenient for users to thoroughly clean the residues without removing the device itself. Furthermore, since the collection container can be inserted and assembled inside the device, it can be reused multiple times without the need for separate carrying or storage.

[0054] Please see Figures 1 to 10 The present application provides an aerosol generating device that can be used to heat an aerosol generating product A to generate a usable aerosol without combustion. The aerosol generating device includes a housing assembly 10, a heating assembly 20, a collection container 30, a power supply assembly, and other functional components as needed.

[0055] Please see Figures 1 to 4 and Figure 9 The housing assembly 10 can be understood as a collection of related structural components that constitute the basic structural framework and outer contour of the aerosol generating device. Through the housing assembly 10, the user can carry, move, hold, or operate the aerosol generating device. The housing assembly 10 has a first socket 10a and a second socket 10b, which are disposed on opposite sides of the housing assembly 10 in a first direction.

[0056] For example, the first direction is Figure 1 In the vertical direction of the aerosol generating device shown, the first insertion port 10a is disposed through the top side wall of the housing assembly 10, and the second insertion port 10b is disposed through the bottom side wall of the housing assembly 10; wherein, the first insertion port 10a is mainly used to provide structural support for inserting or pulling out the aerosol generating product A into the housing assembly 10, and the second insertion port 10b is mainly used to provide structural support for inserting or pulling out the collection container 30 into the housing assembly 10.

[0057] Please see Figures 2 to 4 and Figure 9 The heating component 20 is disposed inside the housing component 10 and electrically connected to the power supply component; the heating component 20 has a heating channel 20a disposed through a first direction, and the two opposite ends of the heating channel 20a in the first direction are respectively connected to the first socket 10a and the second socket 10b.

[0058] Through the connection between the heating channel 20a and the first insertion port 10a, the aerosol generating article A can be inserted into and housed within the heating channel 20a via the first insertion port 10a, so that the heating component 20 can heat the aerosol generating article A to generate a usable aerosol. Through the connection between the second insertion port 10b and the heating channel 20a, the collection container 30 can be inserted into and housed inside the housing assembly 10 via the second insertion port 10b, so that a structural connection is established between the collection container 30 and the heating component 20.

[0059] For example, please refer to Figure 3 The heating component 20 includes a heating tube 21 electrically connected to the power supply component. The tube wall of the heating tube 21 forms a heating channel 20a (that is, the heating channel 20a is equivalent to the tube space of the heating tube 21). When the aerosol generating product A is inserted and housed in the heating tube 21, the heating tube 21 can directly heat the aerosol generating product A under the action of the power supply component.

[0060] For example, the heating component 20 includes a receiving tube and a heating element. The tube wall of the receiving tube forms a heating channel 20a, and the heating element can be a needle-shaped structure or a column-shaped structure. The heating element is fixedly disposed inside the receiving tube and electrically connected to the power supply component. When the aerosol generating product A is inserted and housed in the receiving tube, the heating element can be inserted into the aerosol generating product A, so that the heating element can heat the aerosol generating product A under the action of the power supply component.

[0061] Please see Figures 2 to 4 and Figure 9 and Figure 10The collection container 30 is generally a hollow columnar structure with a predetermined length in a first direction and an opening at one end. A collection chamber 30a is formed inside the collection container 30. For ease of distinction and description, the open end of the collection container 30 is defined as the open end of the collection container 30, and the other end of the collection container 30 opposite to the open end in the first direction is defined as the closed end. It can be understood that the collection chamber 30a is connected to the opening of the collection container 30.

[0062] The collection container 30 is detachably connected to the housing assembly 10. Specifically, the collection container 30 is configured to be inserted into the housing assembly 10 via the second socket 10b in a pluggable manner so that the open end of the collection container 30 can be connected to the heating assembly 20. For example, the open end of the collection container 30 is inserted into the heating assembly 20 in an interference fit, so that a sealed communication relationship can be established between the collection chamber 30a and the heating channel 20a.

[0063] In some embodiments, the opening end of the collection container 30 is provided with a sealing structure, which can resist the heating component to ensure that the collection chamber 30a is sealed and connected to the heating channel 20a.

[0064] For example, please refer to Figure 3 and Figure 10 The sealing structure includes a sealing ring 31, which can be fitted around the opening end. Correspondingly, the heating assembly 20 also has a connecting channel 20b that connects to the heating channel 20a. After the collection container 30 is inserted into the housing assembly 10, the opening end of the collection container 30 can be inserted into the connecting channel 20b, thereby clamping and fixing the sealing ring 31 between the outer peripheral wall of the opening end and the channel wall of the connecting channel 20b. Thus, the collection chamber 30a and the heating channel 20a can be sealed and connected, and the friction force generated by the sealing ring 31 can be fully utilized to prevent the collection container 30 from accidentally detaching from the heating assembly 20 or falling out of the housing assembly 10.

[0065] Of course, the connecting channel 20b can also be omitted, and the open end of the collecting container 30 can be directly inserted into the heating channel 20a to clamp and fix the sealing ring 31 between the outer peripheral wall of the open end and the channel wall of the heating channel 20a.

[0066] For example, the sealing structure includes a sealing gasket, which can be disposed on the end face of the open end of the collection container 30; or a flange structure can be provided on the outer peripheral wall of the open end, with the sealing gasket fitted onto the outer wall of the open end and stacked on the flange structure; when the collection container 30 is inserted into the housing assembly 10, the sealing gasket can be used to abut against the heating assembly 20 from the first direction (for example, the structural surface of the heating assembly 20 surrounding the heating channel 20a, or the stepped surface formed at the connection between the connecting channel 20b and the heating channel 20a), thus achieving a sealed connection between the collection chamber 30a and the heating channel 20a.

[0067] Of course, other suitable structural forms or components can be used for the sealing structure, or the interference fit between the collection container 30 and the heating component 20 can be used to replace the sealing structure, thereby ensuring that the collection chamber 30a is sealed and connected to the heating channel 20a; all of these will not be elaborated here.

[0068] With the collection container 30 inserted inside the housing assembly 10, residues inside the device (such as matrix residues that fall off due to the insertion and removal of aerosol-generated product A, fumes formed after the aerosol-generated product A is heated, and condensate formed after the aerosol and hot air cool) can fall and collect in the collection chamber 30a based on the sealed connection between the heating channel 20a and the collection chamber 30a, thereby allowing the collection container 30 to collect and store the residues from inside the device in real time.

[0069] When it is necessary to clean the residue (for example, when the residue in the collection chamber 30a accumulates to a certain amount), simply pull the collection container 30 out of the housing assembly 10 to detach it from the device body and complete the thorough cleaning of the residue outside the device. After cleaning, the collection container 30 can be reinserted into the housing assembly 10.

[0070] Firstly, by using the collection container 30 to collect and store residues inside the device in real time, and cleaning the residues outside the device, not only can the residues be cleaned more thoroughly, but also a series of problems such as affecting the taste and quality of aerosols and corroding internal parts of the device caused by residues depositing or remaining inside the device (e.g., heating channel 20a) can be effectively avoided.

[0071] Secondly, by structurally integrating the collection container 30 with the main body of the device, the collection container 30 can be inserted into the housing assembly 10 in a pluggable manner. This not only avoids the collection container 30 affecting the appearance structure of the main body of the device, but also makes the pluggable operation convenient and quick. The collection container 30 can be reused multiple times without the need for separate carrying or storage, which helps to reduce the operating cost of the aerosol generating device.

[0072] Third, by utilizing the direct structural connection between the collection container 30 and the heating component 20, the residual heat of the heating component 20 can be used to allow the residue to flow smoothly into or fall into the collection chamber 30a before cooling and solidifying, which helps to reduce the amount of residue remaining in the heating component 20 (e.g., the heating channel 20a).

[0073] It should be noted that the description of aerosol generating product A in this article is solely for the purpose of providing a clearer and more detailed understanding of the structure, operation principle, etc., of the aerosol generating device. It is understood that aerosol generating product A does not constitute a limitation on the aerosol generating device. Those skilled in the art should also recognize that common aerosol generating products A can be simply an aerosol generating matrix with a stable or fixed outline shape (e.g., columnar), or it can be a structure (e.g., a columnar structure) formed by packaging the aerosol generating matrix with packaging materials (e.g., polyamide ester materials, cigarette-specific paper materials, etc.).

[0074] For example, please refer to Figure 2 and Figure 9 A typical aerosol-generating product A can be divided into a matrix section, a cooling section, and a filtration section along its length. The matrix section is formed by packaging materials that hold the aerosol-generating matrix, such as medicinal herbs, spices, or tobacco. By inserting the matrix section into the heating channel 20a, the aerosol-generating matrix in the matrix section can be heated by the heating component 20, thereby generating aerosols.

[0075] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 10 The closed end of the collection container 30 is provided with a limiting structure 30b, which is mainly used to abut against the housing assembly 10 in the first direction to limit the position of the collection container 30 inside the housing assembly 10. For example, the limiting structure 30b includes a protruding structure that protrudes from the outer peripheral surface of the closed end. For example, the protruding structure can protrude from the outer peripheral surface of the closed end around the geometric center line of the collection container 30. Furthermore, the number of protruding structures can be set to multiple, and the multiple protruding structures are arranged at intervals around the geometric center line of the collection container 30.

[0076] Therefore, the limiting structure 30b can abut against the portion of the outer wall of the housing assembly 10 surrounding the second insertion port 10b, thereby confining the collection container 30 in a position where the collection chamber 30a and the heating channel 20a remain in sealed communication. Simultaneously, during the insertion of the collection container 30, excessive pressure or impact on the heating assembly 20 by the collection container 30 can be avoided, preventing damage to the heating assembly 20. Furthermore, the limiting structure 30b provides support for pulling the collection container 30 out of the housing assembly 10.

[0077] In some embodiments, the collection container 30 can also be securely fixed inside the housing assembly 10 based on the limiting structure 30b, for example, a detachable connection structure such as a snap-fit ​​connection or a magnetic connection can be formed between the limiting structure 30b and the housing assembly 10.

[0078] In some embodiments, please refer to Figures 4 to 6 The outer wall of the housing assembly 10 is provided with a recessed structure 10c surrounding the second insertion port 10b. It can be understood that the second insertion port 10b is provided through the bottom wall of the recessed structure 10c. After the collection container 30 is inserted into the housing assembly 10, the recessed structure 10c can accommodate the closed end of the collection container 30 (e.g., including the limiting structure 30b) to prevent the collection container 30 from protruding from the outer wall of the housing assembly 10 and affecting the overall appearance structure of the aerosol generating device, thereby improving the integrity of the overall outer contour structure of the aerosol generating device.

[0079] In some embodiments, please refer to Figure 6 The dimension of the sinkhole structure 10c in the second direction can be set to be larger than the dimension of the closed end in the second direction. For example, the sinkhole structure 10c includes a first sink space for accommodating the closed end and a second sink space connected to one side of the first sink space in the second direction. Here, the second direction refers to a direction perpendicular to the first direction, for example, the first direction is... Figure 1 The vertical direction of the aerosol generating device shown is the second direction. Figure 1 The aerosol generating device shown can be positioned in either the left-right or front-back direction.

[0080] By taking advantage of the size difference between the sink structure 10c and the closed end, the user can insert his fingers or other objects into the sink structure 10c so as to pull the collection container 30 out of the housing assembly 10 by "pulling" the limiting structure 30b.

[0081] In some embodiments, please refer to Figure 10 The outer peripheral wall of the opening end of the collection container 30 is provided with a fixing structure 30c, which is mainly used to restrict and fix the sealing structure such as the sealing ring 31 to the collection container 30. For example, the fixing structure 30c can be a groove structure provided on the outer peripheral wall of the opening end around the geometric center line of the collection container 30, and the sealing ring 31 is fitted onto the opening end and partially inserted into the groove structure.

[0082] By fixing the sealing ring 31 to the collection container 30 using the fixing structure 30c, the sealing ring 31 can move with the collection container 30 during the insertion and removal of the collection container 30. This helps to ensure that the collection chamber 30a and the heating channel 20a are sealed and connected when the collection container 30 and the heating component 20 are structurally connected.

[0083] Of course, as long as the sealing structure such as the sealing ring 31 can be fixed to the collection container 30, other suitable structures can also be used for the fixing structure 30c.

[0084] In addition, in some embodiments, the number of sealing rings 31 can be set to multiple, and the multiple sealing rings 31 are arranged at intervals in the first direction to improve the sealing communication between the collection chamber 30a and the heating channel 20a.

[0085] In some embodiments, please refer to Figure 10 The opening of the collection container 30 (i.e. the port connecting the collection chamber 30a and the outside of the collection container 30) can be configured as a conical opening structure, such as a cone; the diameter of the conical opening gradually decreases towards the closed end along the first direction; in this way, when the collection chamber 30a and the heating channel 20a are sealed and connected, the conical opening structure can guide the residue so that the residue can be collected in the collection chamber 30a.

[0086] In some embodiments, please refer to Figure 9 and Figure 10 The aerosol generating device also includes an adsorption element 32, which is disposed in the collection chamber 30a and is used to adsorb the residue entering the collection chamber 30a, so as to prevent the residue from backflowing out of the collection container 30 due to the aerosol generating device tipping over, or to prevent the residue from overflowing from the collection chamber 30a.

[0087] In specific implementation, the adsorption element 32 can adopt different structural forms or structures made of different materials as needed. For example, the adsorption element 32 can be a structure made of materials with strong adsorption capacity for liquids, such as cotton fibers (i.e., oil-absorbing cotton), activated carbon, graphene, and microporous ceramics (for example, the adsorption element 32 is a columnar structure adapted to the shape of the collection chamber 30a). The adsorption element 32 can also be particulate matter filled in the collection chamber 30a, such as cotton fiber particles, cotton fiber filaments, activated carbon particles, graphene particles, and microporous ceramic particles.

[0088] It is understandable that the adsorption element 32 can be replaced within the collection chamber 30a. For example, during the process of cleaning residues, the adsorption element 32 can be removed from the collection chamber 30a first. After cleaning the collection container 30, the residues can be thoroughly cleaned. Then, a new adsorption element 32 can be replaced, and the collection container 30 can be reassembled into the housing assembly 10. Alternatively, the adsorption element 32 can be detachably installed within the collection chamber 30a. In this way, during the process of cleaning residues, the collection container 30 and the adsorption element 32 can be cleaned specifically, and then the two can be combined to achieve reusability of the collection container 30 and the adsorption element 32.

[0089] In some embodiments, please refer to Figure 10 The adsorption element 32 is generally a columnar structure adapted to the shape of the collection chamber 30a, and the dimension of the adsorption element 32 in the first direction is smaller than the dimension of the collection chamber 30a in the first direction. After the adsorption element 32 is inserted into the collection chamber 30a, the collection chamber 30a has sufficient space to collect the residue, so that the residue can flow smoothly into or fall into the collection chamber 30a. At the same time, the adsorption effect of the adsorption element 32 on the residue can "lock" the residue in the collection chamber 30a.

[0090] In some embodiments, please refer to Figure 3 , Figure 7 and Figure 8 The housing assembly 10 includes an outer shell 11, an inner support 12, a first end cap 13, and a second end cap 14. For ease of distinction and description, the two opposite ports of the outer shell 11 along its length (i.e., the first direction) are defined as the first port and the second port, respectively. The inner support 12 is disposed inside the outer shell 11. The first end cap 13 is disposed at the end of the inner support 12 near the first port, thereby closing the first port. The second end cap 14 is disposed at the end of the inner support 12 near the second port, thereby closing the second port. A first insertion port 10a penetrates the first end cap 13, and a second insertion port 10b penetrates the second end cap 14 (as described above, the recessed structure 10c can be disposed on the outer wall surface of the second end cap 14).

[0091] As for the heating component 20, it can be installed and fixed to the housing component 10 in different ways as needed. For example, the heating component 20 can be clamped and fixed between the first end cover 13 (or the inner bracket 12) and the second end cover 14, or the heating component 20 can be fixed on the inner bracket 12.

[0092] Thus, the outer casing 11, the first end cap 13, and the second end cap 14 together form the internal space of the housing assembly 10, while the inner support 12 can provide structural support for related components inside the housing assembly 10. For example, by supporting the first end cap 13 and the second end cap 14, the overall structural stability of the housing assembly 10 can be ensured. Furthermore, the inner support 12 can be used to stably arrange the heating component 20, the power supply component, etc., inside the housing assembly 10.

[0093] In some embodiments, please refer to Figure 7 and Figure 8The first end cap 13 and the inner support 12, as well as the second end cap 14 and the inner support 12, can be connected by a detachable method (e.g., snap-fit ​​connection). This allows the inner support 12, the first end cap 13, and the second end cap 14 to be pre-assembled into a shell frame. After the heating component 20, the power supply component, etc., are assembled into the shell frame, the outer sleeve 11 can be placed on the outside of the shell frame to complete the assembly of the aerosol generating device quickly and easily. This not only effectively reduces the assembly difficulty of the aerosol generating device, but also facilitates the disassembly and maintenance of the aerosol generating device.

[0094] In other embodiments, the housing assembly 10 may also adopt other suitable structural forms, such as the outer shell 11 and the first end cap 13 combined to form a first structure (for example, the outer shell 11 and the first end cap 13 are an integral structure), and the inner support 12 and the second end cap 14 combined to form a second structure (for example, the inner support 12 and the second end cap 14 are an integral structure). By dispersing or concentrating the heating component 20, the power supply component, etc. in the first structure or the second structure, and then inserting the second structure into the first structure, the aerosol generating device can be conveniently and quickly assembled. All of these will not be elaborated here.

[0095] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 9 and combined Figure 7 and Figure 8 The inner support 12 divides the internal space of the housing assembly 10 into a first space 10d and a second space 10e arranged side by side in a second direction (e.g., left-right direction); wherein the heating assembly 20 and the collection container 30 are disposed in the first space 10d, while at least a portion of the power supply assembly may be disposed in the second space 10e.

[0096] For example, please refer to Figure 3 The power supply component is assembled from the battery cell 51 and the circuit board assembly including the circuit board 52. The heating component 20, the battery cell 51 and the circuit board assembly are electrically connected. The battery cell 51 is fixedly installed in the second space 10e, and the circuit board 52 is fixed on the inner support 12. For example, the inner support 12 is provided with a slot structure 12a extending in the first direction. The circuit board 52 can be conveniently and quickly inserted and fixed to the inner support 12 by means of the slot structure 12a. The circuit board 52 can be located in the first space 10d or in the second space 10e.

[0097] Therefore, by using the inner support 12 to divide the internal space of the housing assembly 10, it is not only beneficial to realize the quick assembly and disassembly of the heating assembly 20 and the power supply assembly, making the internal structural layout of the aerosol generating device more reasonable, but also, by arranging the heating assembly 20 (together with the collection container 30) and the power supply assembly in different structural spaces, it can provide support to prevent aerosols or residues from entering the power supply assembly.

[0098] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 The heating assembly 20 includes a heating tube 21, a support tube 22, a first bracket 23, and a second bracket 24. As mentioned above, the tube wall of the heating tube 21 forms a heating channel 20a, and the heating tube 21 is electrically connected to the power supply assembly. The support tube 22 is coaxially spaced from the heating tube 21 in the first direction, and the tube wall of the support tube 22 forms an insertion channel 20c (which can also be understood as the tube space of the support tube 22 being the insertion channel 20c). The end of the support tube 22 away from the heating tube 21 is connected to the second end cap 14 (or the inner bracket 12) (e.g., abutting, inserting, etc.) so that the insertion channel 20c and the second socket 10b are connected.

[0099] The first bracket 23 is connected to the first end cap 13 (or inner bracket 12) (e.g., abutting, inserting, etc.), and the end of the heating tube 21 away from the support tube 22 is connected to the first bracket 23 (e.g., abutting, inserting, etc.), and the first bracket 23 is provided with a first through hole 23a that connects the first socket 10a and the heating channel 20a.

[0100] The second bracket 24 is provided with a second through hole that connects the heating channel 20a and the insertion channel 20c; in some embodiments, the second through hole can be understood as the connecting channel 20b mentioned above; the second bracket 24 is connected between the heating tube 21 and the support tube 22, and the ends of the heating tube 21 and the support tube 22 that are close to each other in the first direction are respectively inserted into the second through hole, or the ends of the heating tube 21 and the support tube 22 that are close to each other in the first direction are respectively abutted against the second bracket 24.

[0101] On the one hand, by utilizing the sequential connection between the first insertion port 10a, the first through hole 23a, the heating channel 20a, the second through hole (or the connecting channel 20b), the insertion channel 20c, and the second insertion port 10b, a channel structure can be formed that runs through the housing assembly 10 in the first direction, so that the aerosol generating product A and the collection container 30 can be inserted and removed from opposite sides of the housing assembly 10 respectively.

[0102] Specifically, at least a portion of the aerosol-generating product A is inserted into the heating channel 20a via the first insertion port 10a, and the heat generated by the heating tube 21 can be used to heat the aerosol-generating product A; while at least a portion of the collection container 30 is inserted into the insertion channel 20c and the second through hole via the second insertion port 10b, thereby ensuring that the collection chamber 30a can form a sealed communication relationship with the heating channel 20a while establishing a structural connection between the collection container 30 and the heating component 20.

[0103] On the other hand, by utilizing the cooperation between components such as the heating tube 21, the support tube 22, the first bracket 23, and the second bracket 24, the heating assembly 20 can be easily and quickly assembled in the shell frame. At the same time, with the help of the support tube 22 (such as the insertion channel 20c), it can not only provide positioning and guidance for the insertion and removal of the collection container 30, ensuring that the open end of the collection container 30 can be accurately and smoothly inserted into the second through hole (i.e., the connection channel 20b), but also structurally isolate the collection container 30 from other components inside the shell assembly 10 (such as the power supply assembly), to prevent the residue collected by the collection container 30 from accidentally contaminating the power supply assembly, etc.

[0104] In other embodiments, the support tube 22 may be omitted as needed, and the heating tube 21 may be fixed inside the housing assembly 10 by means of the cooperation of the second bracket 24 and the first bracket 23, and structural support may be provided for the insertion and removal of the collection container 30; of course, the heating assembly 20 may also adopt other suitable structural forms, which will not be described in detail here.

[0105] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 The heating assembly 20 also includes a heat insulation tube 25, which is sleeved around the heating tube 25, and the two ends of the heat insulation tube 25 opposite to each other in the first direction are connected to the first bracket 23 and the second bracket 24 on the corresponding side (e.g., abutting, plugging connection, etc.).

[0106] The heat insulation pipe 25 forms a thermal barrier between the heating component 20, the housing component 10, and the power supply component, thereby improving the heat utilization rate and facilitating the full heating of the aerosol-generated product A. In some embodiments, the first support 23, the second support 24, the support pipe 22, etc., may also be made of heat insulation material to further enhance the thermal insulation effect.

[0107] In some embodiments, please refer to Figure 4 and combined Figure 2The second support 24 is provided with a limiting structure 24a. The limiting structure 24a can be a protrusion structure protruding from the wall of the second through hole (or connecting channel 20b), or a stepped surface structure formed in the second through hole based on the change in the inner diameter of the first through hole (or connecting channel 20b).

[0108] The limiting structure 24a can form a structural isolation and restriction between the aerosol generating article A and the collection container 20. For example, by holding the aerosol generating article A, it can prevent the aerosol generating article A from extending into the insertion channel 20c or the collection chamber 30a. Similarly, by holding the collection container 20, the position of the collection container 20 within the housing assembly 10 can be limited, preventing the collection container 20 from being excessively inserted into the heating channel 20a.

[0109] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
