Description

Technical Field

[0001] This application belongs to the technical field of atomizing devices, and specifically relates to an atomizing device. Background Technology

[0002] Nebulizers atomize solid or liquid aerosol matrix into a gaseous state, and are generally used in medical, nicotine delivery, and home applications. Depending on the atomization method, related technologies fall into two categories: heated atomization and ultrasonic atomization. Some atomizers employ a sealed structure, such as disposable nebulizers, where the power supply component is embedded and fixed, making disassembly difficult. After use, the entire atomizer is discarded, making effective disassembly and recycling of the power supply component impossible, posing a potential environmental pollution risk. Furthermore, the structure fixing the power supply component often uses welding or hot pressing methods, which are not conducive to subsequent testing or structural adjustments.

[0003] In addition, existing quick-release solutions for power supply components are mostly concentrated on top plug-in structures, which interferes with the design of thin and light components. They usually require disassembling the nozzle and the upper shell, which is cumbersome, complicated to assemble, and inconvenient for maintenance. Utility Model Content

[0004] The purpose of this application is to provide an atomizing device that can solve at least some of the problems mentioned above.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides an atomizing device, including a housing assembly, a battery cell assembly, and a bottom cover assembly. The bottom cover assembly is detachably connected to the tail of the housing assembly. The bottom cover assembly and the housing assembly enclose a receiving space. The battery cell assembly is housed within the receiving space and is fixed relative to the bottom cover assembly. The battery cell assembly is configured to be movable away from the housing assembly together with the bottom cover assembly.

[0006] In this embodiment, the housing assembly serves as the external support and internal component housing of the atomizing device, with its core structural feature being the open design at the tail (bottom). To enable the detachable connection and disassembly / removal of the bottom cover assembly, the tail of the housing assembly can be fitted with a suitable connecting structure. The open design at the bottom of the housing assembly is not a simple opening structure, but rather needs to meet the dual requirements of enclosing a storage space and facilitating bottom disassembly / removal. It forms a semi-closed cavity through its sidewalls and top structure, providing a stable installation space for the battery cell assembly. Furthermore, the bottom connecting structure secures it to the bottom cover assembly, allowing the battery cell assembly to be detached from the housing assembly along with the bottom cover assembly. This ensures that subsequent assembly / removal can be completed from the bottom without disassembling other parts of the housing assembly, effectively simplifying the assembly / removal process. Furthermore, the connection structure between the bottom cover assembly and the tail of the housing assembly must precisely match the tail interface of the housing assembly. This could include external threads (matching the internal threads of the housing), elastic clips (matching the clip grooves of the housing assembly), or positioning holes (matching the positioning protrusions of the housing). The connection method must also facilitate easy assembly and disassembly, allowing for installation and removal without the need for complex tools. Secondly, the bottom cover assembly must also have a connection structure with the battery cell assembly, such as a battery cell fixing slot, electrode connection terminals, or an elastic clamping structure. This allows the battery cell assembly to be directly fixed to the bottom cover assembly, forming an integrated module of the bottom cover assembly and the battery cell assembly. This enables the battery cell assembly to be removed from the housing assembly along with the bottom cover assembly. The key to this structural design is that when the bottom cover assembly is removed from the bottom of the housing, the battery cell assembly can be removed along with the bottom cover, eliminating the need for separate disassembly of the battery cell and greatly simplifying the assembly and disassembly process.

[0007] Furthermore, the dimensions of the accommodating space formed by the housing assembly and the bottom cover assembly must be precisely matched with the shape of the cell assembly, with only necessary assembly gaps reserved to avoid wasting internal space. This means that the inner wall contour of the housing assembly must be closely fitted to the external shape of the cell assembly (such as cylindrical or square). The connection between the bottom cover assembly and the cell assembly can be designed as an embedded or stacked structure, rather than taking up too much extra space.

[0008] In this embodiment, the aforementioned design ensures a precise fit between the housing assembly and the battery cell assembly, eliminating redundant space and significantly reducing the overall size of the device. Furthermore, the integrated design of the bottom cover assembly and the battery cell assembly eliminates the need for separate battery cell mounting brackets or connecting cables, reducing the number of internal components and further compressing the internal space. This compact structure not only meets the market demand for miniaturized and portable atomizing devices but also reduces material usage and production costs. Simultaneously, the integrated modular design of the bottom cover assembly and the battery cell assembly allows for direct replacement of the battery cell assembly via module swapping, further enhancing maintenance convenience.

[0009] Optionally, in an embodiment of this application, the housing assembly includes a housing and a first snap-fit ​​structure, the first snap-fit ​​structure being disposed at one end of the housing near the bottom cover assembly, and the bottom cover assembly and the first snap-fit ​​structure being detachably connected.

[0011] Optionally, in this embodiment, the housing assembly further includes an inner shell, which is a cylindrical structure and disposed within the accommodating space. When the outer shell is fitted around the outer periphery of the inner shell, the inner shell and the outer shell are coaxial. The bottom cover assembly includes a second cover body, which is disposed on the side of the first cover body near the battery cell assembly. The inner shell is fitted around the outer periphery of the second cover body, and the inner shell and the second cover body can enclose each other to form an accommodating cavity, within which the battery cell assembly is disposed.

[0012] Optionally, in this embodiment, the first snap-fit ​​structure is deformable; when the first snap-fit ​​structure is deformed, the first snap-fit ​​structure can be separated from the bottom cover assembly; when the first snap-fit ​​structure recovers its deformation, the first snap-fit ​​structure can be connected to the bottom cover assembly.

[0013] Optionally, in the embodiments of this application, one of the first snap-fit ​​structure and the second snap-fit ​​structure has a groove and the other has a protrusion, and the groove and the protrusion are adapted to each other.

Detailed Implementation

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0022] The atomizing device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0023] See Figures 1 to 3 The embodiments of this application provide an atomizing device, including a housing assembly 10, a battery cell assembly 20, and a bottom cover assembly 30. The bottom cover assembly 30 is detachably connected to the tail of the housing assembly 10. The bottom cover assembly 30 and the housing assembly 10 enclose a receiving space 40. The battery cell assembly 20 is housed in the receiving space 40, and the battery cell is relatively fixedly connected to the bottom cover assembly 30. The battery cell assembly 20 is configured to be able to move away from the housing assembly 10 together with the bottom cover assembly 30.

[0024] In this embodiment, the housing assembly 10 serves as the external support and internal component housing of the atomizing device, and its core structural feature is the open design at the tail (bottom). To enable the detachable connection and disassembly / removal of the bottom cover assembly 30, the tail of the housing assembly 10 can be achieved by setting a suitable connection structure. The open design at the bottom of the housing assembly 10 is not a simple opening structure, but rather needs to meet the dual requirements of enclosing the housing space 40 and bottom disassembly / removal. It forms a semi-closed housing cavity 41 through its side walls and top structure, providing a stable installation space for the battery cell assembly 20. It is also relatively fixed to the bottom cover assembly 30 through the bottom connection structure, and the battery cell assembly 20 can also be disassembled from the housing assembly 30 along with the bottom cover assembly 30. This ensures that the atomizing device can be disassembled / removed from the bottom without disassembling other parts of the housing assembly 10, effectively simplifying the disassembly / removal steps.

[0025] Furthermore, the bottom cover assembly 30 needs to match the connection structure at the tail of the housing assembly 10, such as providing external threads (which engage with the internal threads of the housing), elastic clips (which engage with the clip grooves of the housing assembly 10), or positioning holes (which engage with the positioning protrusions 122 of the housing). The connection method must also meet the requirements for convenient assembly and disassembly, allowing for installation and removal without the need for complex tools. Secondly, the bottom cover assembly 30 also needs to have a connection structure with the battery cell assembly 20, such as providing a battery cell fixing groove, electrode connection terminals, or an elastic clamping structure, so that the battery cell assembly 20 can be directly fixed to the bottom cover assembly 30, forming an integrated module of the bottom cover assembly 30 and the battery cell assembly 20. This allows the battery cell assembly 20 to be removed from the housing assembly 10 together with the bottom cover assembly 30. The key to the above structural design is that when the bottom cover assembly 30 is removed from the bottom of the housing assembly 10, the battery cell assembly 20 can be removed along with the bottom cover assembly 30, eliminating the need for separate disassembly of the battery cell and greatly simplifying the assembly and disassembly process.

[0026] Furthermore, the dimensions of the accommodating space 40 formed by the housing assembly 10 and the bottom cover assembly 30 must be precisely matched with the shape of the cell assembly 20, with only necessary assembly gaps reserved to avoid wasting internal space. This means that the inner wall contour of the housing assembly 10 must be highly fitted to the external shape (such as cylindrical or square) of the cell assembly 20. The connection between the bottom cover assembly 30 and the cell assembly 20 can be designed as an embedded or stacked structure, rather than occupying too much extra space.

[0027] In this embodiment, through the above-described configuration, the accommodating space 40 of the housing assembly 10 is precisely matched with the battery cell assembly 20, with no redundant space, thus significantly reducing the overall size of the device. Furthermore, the integrated design of the bottom cover assembly 30 and the battery cell assembly 20 avoids the need for separate battery cell mounting brackets or connecting cables, reducing the number of internal components and further compressing the internal space. This compact structure not only meets the market demand for miniaturization and portability of atomizing devices but also reduces material usage and production costs. Simultaneously, the integrated modular design of the bottom cover assembly 30 and the battery cell assembly 20 allows for direct replacement of the battery cell assembly 20 by simply replacing the module, further improving maintenance convenience.

[0028] It should be noted that in traditional atomizing devices, replacing the battery cell assembly 20 often requires disassembling the entire device (including the top atomizing component), which can easily damage other intact parts (such as the housing and mouthpiece), leading to overall scrapping. In this embodiment, only the bottom cover assembly 30 needs to be removed to replace the battery cell, while other intact parts can continue to be used, reducing overall scrapping due to partial failures and lowering the amount of electronic waste generated. During disposal, the bottom cover assembly 30 can be quickly separated from the housing assembly 10 through bottom disassembly. The battery cell assembly 20, as the core recyclable component, can be extracted from the housing assembly 10 along with the bottom cover assembly 30, avoiding the difficulties in recycling and resource waste caused by the difficulty in separating components in traditional devices. This maintainable and easily recyclable design aligns with the development concepts of green manufacturing and circular economy, reducing environmental pollution.

[0029] Optionally, in this embodiment of the application, the housing assembly 10 includes a housing 11 and a first snap-fit ​​structure 12. The first snap-fit ​​structure 12 is disposed at one end of the housing 11 near the bottom cover assembly 30, and the bottom cover assembly 30 and the first snap-fit ​​structure 12 are detachably connected.

[0030] In this embodiment, the first snap-fit ​​structure 12 can be an elastic snap-fit ​​structure. For example, 3-4 elastic protrusions are spaced circumferentially on the inner or outer wall of the outer casing 11 near the bottom. The ends of the protrusions are designed as inclined guide surfaces (to facilitate smooth snap-fit ​​during assembly of the bottom cover assembly 30), and a certain elastic deformation space is reserved at the root of the protrusions (to ensure that they can deform and detach under force during disassembly). The first snap-fit ​​structure 12 can also be a slot protrusion 122 mating structure, that is, an annular slot or axial strip slot is opened on the inner wall of the bottom of the outer casing 11. The inner wall of the slot is provided with anti-slip texture (to prevent loosening after connection), and a force notch is reserved for disassembly (to facilitate separation by tools or fingers).

[0031] Furthermore, the first snap-fit ​​structure 12 needs to precisely correspond to the connection part of the bottom cover assembly 30, and is usually set in the annular area extending inward or outward from the bottom port of the housing 11. If the bottom cover assembly 30 is a sleeve type (the bottom cover assembly 30 is sleeved on the bottom of the housing 11 from the outside), then the first snap-fit ​​structure 12 can be set on the outer wall of the housing 11; if the bottom cover assembly 30 is an embedded type (the bottom cover assembly 30 is embedded into the bottom of the housing 11 from the inside), then the first snap-fit ​​structure 12 is set on the inner wall of the housing 11, and the height of the structure does not exceed the plane of the port of the housing 11 (to avoid occupying extra space and ensure a compact structure).

[0032] In this embodiment, the design of the first snap-fit ​​structure 12 not only affects the connection between the outer shell 11 and the bottom cover, but also plays a key role in optimizing the compactness of the internal accommodating space 40. Compared with traditional threaded connections (which require reserved space for thread engagement), the first snap-fit ​​structure 12 does not require additional thread length, which can significantly shorten the structural space occupied at the bottom of the outer shell 11 and further compress the overall volume of the device. At the same time, the first snap-fit ​​structure 12 usually adopts an embedded design, such as setting the elastic protrusion in the recessed area of ​​the inner wall of the outer shell 11, or opening the slot in the annular step at the port of the outer shell 11, to avoid the structure protruding outward or inward, ensuring that the inner wall of the outer shell 11 is flat and does not affect the close fitting and assembly of the battery cell assembly 20 in the accommodating space 40, maintaining the compact layout of the internal space.

[0033] Optionally, in this embodiment of the application, the bottom cover assembly 30 includes a first cover 31, the first cover 31 and the outer shell 11 enclose a receiving space 40, and a second snap-fit ​​structure 311 is provided on the side of the first cover 31 near the cell assembly 20, and the second snap-fit ​​structure 311 and the first snap-fit ​​structure 12 are detachably connected.

[0034] In this embodiment, the bottom cover assembly 30 needs to be equipped with a corresponding second snap-fit ​​structure 311 that is compatible with the first snap-fit ​​structure 12, forming an interlocking connection. If the first snap-fit ​​structure 12 is an elastic protrusion, the bottom cover assembly 30 needs to have an annular groove or positioning hole at the corresponding position. The inner wall of the groove needs to be designed with a guide structure that matches the inclined surface of the protrusion to ensure that when the bottom cover assembly 30 is pressed axially, the protrusion can slide into the groove along the guide surface to achieve snap-fit ​​fixation. During disassembly, the bottom cover is pulled axially or rotated slightly to cause the protrusion to deform under force and disengage from the groove, thus completing the separation. If the first snap-fit ​​structure 12 is a groove, the bottom cover assembly 30 needs to be equipped with a corresponding elastic protrusion 122. The protrusion 122 is made of plastic with good elasticity. During assembly, the protrusion 122 is deformed under pressure and enters the groove. After it is in place, it springs back and locks in place. During disassembly, the protrusion 122 is squeezed to disengage from the groove.

[0035] In this embodiment, the second snap-fit ​​structure 311 reduces the number of parts, eliminating the need for additional screws, clips, or other connectors. The first cover 31 and the outer shell 11 can be connected via their own snap-fit ​​structure, reducing supply chain complexity and procurement costs. Simultaneously, it further reduces the difficulty of replacing the battery cell assembly 20, allowing users to disassemble the bottom cover and replace the battery cells without specialized knowledge, avoiding the complete scrapping of the device due to complex maintenance.

[0036] Optionally, in this embodiment, the housing assembly 10 further includes an inner shell 13, which is a cylindrical structure and is disposed within the accommodating space 40. When the outer shell 11 is fitted around the outer periphery of the inner shell 11, the inner shell 13 and the outer shell 11 are coaxial. The bottom cover assembly 30 includes a second cover 32, which is disposed on the side of the first cover 31 near the cell assembly 20. The inner shell 13 is fitted around the outer periphery of the second cover 32, and the inner shell 13 and the second cover 32 can enclose each other to form an accommodating cavity 41, within which the cell assembly 20 is disposed.

[0037] In this embodiment, the inner shell 13 is disposed within the receiving space 40. When the shell assembly 10 and the bottom cover assembly 30 are assembled, the outer shell 11 and the inner shell 13 are coaxially arranged to avoid interference between the inner shell 13 and the outer shell 11 or the second cover 32. The inner shell 13 serves to limit and guide the insertion and installation of the battery cell assembly 20, ensuring that the battery cell assembly 20 is inserted in an accurate direction and remains stable during operation, while also preventing the battery cell from loosening due to vibration. The outer periphery of the second cover 32 must mate with the inner wall of the inner shell 13. If the inner shell 13 is provided with a guide groove, the outer wall of the second cover 32 must be provided with guide ribs of the same height to ensure smooth insertion without jamming. It should be noted that the receiving cavity 41 is only used to place the battery cell assembly 20 and is completely separated from other spaces within the outer shell 11. This avoids structural interference between the battery cell assembly 20 and other components and facilitates subsequent maintenance by operating only on the receiving cavity 41 without affecting other functional areas.

[0038] Optionally, in this embodiment, the first snap-fit ​​structure 12 is deformable; when the first snap-fit ​​structure 12 is deformed, the first snap-fit ​​structure 12 can be separated from the bottom cover assembly 30; when the first snap-fit ​​structure 12 recovers its deformation, the first snap-fit ​​structure 12 can be connected to the bottom cover assembly 30.

[0039] In this embodiment, traditional rigid snap-fit ​​structures require additional spring mounting slots or limiting structures, occupying radial space. However, the deformable first snap-fit ​​structure 12 and the outer shell 11 are integrally injection molded, requiring no additional components and achieving connection solely through structural deformation. The elastic properties of the deformable first snap-fit ​​structure 12 allow for slight dimensional deviations between it and the second snap-fit ​​structure 311, eliminating the need for a large clearance as required by rigid structures. This allows for a tighter fit with other internal components, avoiding wasted space due to gaps.

[0040] In practical applications, when assembling the housing assembly 10 and the bottom cover assembly 30, or when disassembling the housing assembly 10 and the bottom cover assembly 30, the first snap-fit ​​structure 12 deforms to allow the housing assembly 10 to insert into or disengage from the bottom cover assembly 30. After the first snap-fit ​​structure 12 is inserted into the bottom cover assembly 30, it returns to its original shape, thus achieving the connection between the housing assembly 10 and the bottom cover assembly 30.

[0041] Furthermore, the deformable structure has a self-resetting characteristic, eliminating the need for precise alignment or additional tools during assembly. Once assembled, the structure automatically springs back and locks in place, requiring no manual pressing or rotation for locking, effectively improving installation efficiency.

[0042] Optionally, in the embodiments of this application, one of the first snap-fit ​​structure 12 and the second snap-fit ​​structure 311 has a groove portion 3112 and the other has a protrusion portion 122, and the groove portion 3112 and the protrusion portion 122 are adapted to each other.

[0043] In this embodiment, if the first snap-fit ​​structure 12 of the outer shell 11 has a protrusion 122, then the groove 3112 on the second snap-fit ​​structure 311 of the first cover 31 needs to be designed as an annular groove or an axial strip groove. The width of the annular groove needs to match the thickness of the protrusion, and the groove depth needs to be greater than the height of the protrusion to prevent the protrusion from falling off. At the same time, an inclined guide surface needs to be designed at the entrance of the groove 3112 to guide the protrusion 122 to slide smoothly into the groove during assembly, reducing assembly resistance; small anti-slip protrusions can be provided on the inner side of the groove 3112. When the protrusion 122 is fully snapped in, the protrusions can form a slight clamping with the side of the protrusion 122 to prevent the protrusion 122 from sliding out of the groove 3112 due to vibration.

[0044] If the first snap-fit ​​structure 12 of the outer shell 11 is a recess 3112, then the second snap-fit ​​structure 311 of the first cover 31 needs to be designed as a protrusion 122. The protrusions 122 are typically designed with evenly distributed circumferentially (e.g., 3-4), and are made of highly elastic modified plastic. The head of the protrusion 122 is designed as an arc (to reduce frictional resistance during assembly), and the root is designed as a narrow neck structure (to ensure sufficient space for elastic deformation). The height of the protrusion 122 needs to be slightly greater than the depth of the recess. When the first cover 31 is inserted into the outer shell 11, the protrusion 122 deforms under pressure and enters the recess 3112. After reaching its position, it springs back, and the head is locked within the recess 3112, forming an axial limit.

[0045] Optionally, in this embodiment of the application, the first snap-fit ​​structure 12 includes a first body 121 and a protrusion 122. The first body 121 is connected to the outer shell 11, and the protrusion 122 is disposed at the end of the first body 121 near the bottom cover assembly 30. The protrusion 122 protrudes from the first body 121 in a direction away from the battery cell.

[0046] In this embodiment, the first body 121 can be integrally injection molded with the outer shell 11. The first body 121, serving as the support for the protrusion 122, can adopt a cantilevered elongated structure or a ring-shaped sheet structure to adapt to the inner wall shape of the outer shell 11. If the outer shell 11 is a cylindrical structure, the first body 121 is typically a cantilever evenly distributed along the circumference of the inner wall; if the outer shell 11 is square, the first body 121 can be an L-shaped cantilever fitting the four corners, or a ring-shaped structure surrounding the inner wall. Reinforcing ribs can be provided at the connection between the first body 121 and the protrusion 122 to prevent the first body 121 from breaking at its root under stress.

[0047] The protrusion 122 is key to the engagement with the second snap-fit ​​structure 311 (groove 3112). Its head can be designed as a wedge-shaped barb with a certain bevel angle (to facilitate the sliding of the groove 3112 into the assembly) and a certain height (to ensure axial positioning after snapping). The root of the protrusion 122 transitions to the first body 121 through an arc. The width of the protrusion 122 needs to match the width of the groove 3112 of the second snap-fit ​​structure 311 to form a slight interference fit and prevent loosening after snapping. Furthermore, to improve the reliability of the snap-fit ​​connection, the protrusion 122 may be designed with the following details: Anti-slip texture: Tiny anti-slip textures are made on the side of the barb of the protrusion 122, which interlock with the inner wall of the groove 3112 to increase static friction and prevent axial movement caused by vibration. Guide chamfer: A guide chamfer is provided at the bottom of the protrusion 122 (on the side near the end of the first body 121). During assembly, the groove 3112 of the second snap-fit ​​structure 311 can be precisely aligned with the protrusion 122, reducing the difficulty of alignment.

[0048] Optionally, in this embodiment of the application, the second snap-fit ​​structure 311 includes a second body 3111 and a groove portion 3112. The second body 3111 is connected to the bottom cover, and the groove portion 3112 is recessed on the side of the second body 3111 facing the battery cell.

[0049] In this embodiment, the second body 3111 is structurally adapted to the first cover 31 of the bottom cover assembly 30, and can be integrally injection molded with the first cover 31. The groove portion 3112 is key to the engagement with the protrusion 122 of the first snap-fit ​​structure 12. Its shape and size must be adapted to the protrusion 122, while taking into account the snap-fit ​​stability and ease of disassembly and assembly. The opening of the groove portion 3112 faces the direction of the battery cell. The groove opening can be designed as a flared guide structure to guide the protrusion 122 to slide in smoothly. The bottom of the groove can be set as an arc transition surface. Anti-slip grooves can be opened on the inner side of the groove wall to engage with the anti-slip texture of the protrusion 122, increase static friction, and prevent loosening after snap-fit.

[0050] Furthermore, to improve the reliability and durability of the snap-fit ​​connection, the groove portion 3112 may be designed with the following details: Wear-resistant coating: A wear-resistant coating is sprayed on the groove wall and bottom surface of the groove 3112 to reduce frictional loss when the protrusion 122 is repeatedly inserted / removed, thereby improving the service life of the groove 3112.

[0051] Optionally, in this embodiment of the application, the number of first snap-fit ​​structures 12 is at least two, and at least two first snap-fit ​​structures 12 are arranged at intervals around the outer shell 11.

[0052] In this embodiment, the number of first snap-fit ​​structures 12 needs to balance connection stability and structural lightweighting. A common design uses 2-4 structures, with the specific selection determined based on the size of the housing 11 and the stress requirements. Two first snap-fit ​​structures 12 are suitable for miniaturized housings 11, symmetrically arranged at both ends of the housing 11's diameter. This satisfies the basic radial limiting requirements while reducing the structure's footprint on internal space and lowering injection molding difficulty. Three to four first snap-fit ​​structures 12 are suitable for medium to large housings 11 or high-power atomizing devices (heavy battery cells, high vibration risk). Three structures are arranged in an equilateral triangle, and four in a square. Multi-point support improves radial stress uniformity and avoids structural damage caused by concentrated stress at a single snap-fit ​​point.

[0053] It should be noted that each of the first snap-fit ​​structures 12 must be distributed at equal angles around the central axis of the outer shell 11 to avoid excessive local stress due to uneven spacing. The tops of the protrusions 122 of all the first snap-fit ​​structures 12 must be on the same circumferential surface to ensure synchronous engagement with the grooves 3112 of the second snap-fit ​​structure 311, avoiding assembly tilting caused by one structure snapping in first. The layout must avoid other structures on the inner wall of the outer shell 11 to prevent collisions with other components during deformation (e.g., when the first body 121 deforms radially, the cantilever end should not contact the outer wall of the inner shell 13).

[0054] It should also be noted that at least two first snap-fit ​​structures 12 need to achieve synchronous deformation and synchronous engagement. Therefore, the structural design must maintain consistency. For example, the dimensions of the first body 121 and the protrusion 122 of all first snap-fit ​​structures 12 should be the same, and the materials should be the same to ensure that the elastic modulus and deformation stroke of each structure are the same. The wedge-shaped slope angle and guide chamfer dimensions of each protrusion 122 should be uniform and precisely matched with the guide slope of the groove 3112 of the second snap-fit ​​structure 311 to ensure that multiple sets of structures are guided synchronously during assembly and to avoid engagement delay caused by deviation of the guide angle of a certain structure.

[0055] In the embodiments of this application, compared with a single set of first snap-fit ​​structures 12, at least two first snap-fit ​​structures 12 arranged in a ring have the beneficial effects of improving connection stability, assembly reliability and structural safety.

[0056] Optionally, in this embodiment of the application, the number of second snap-fit ​​structures 311 is at least two, at least two second snap-fit ​​structures 311 are disposed on the inner side of the first cover 31, and at least two second snap-fit ​​structures 311 are disposed corresponding to the first snap-fit ​​structure 12.

[0057] In this embodiment, the number of second snap-fit ​​structures 311 must be exactly the same as the number of first snap-fit ​​structures 12, forming a one-to-one correspondence. Two second snap-fit ​​structures 311, adapted to two symmetrically distributed first snap-fit ​​structures 12, are suitable for miniaturized atomizing devices. While meeting basic connection requirements, they reduce the structural occupancy inside the first cover 31, reserving more space 40 for the battery cell assembly 20. Three to four second snap-fit ​​structures 311, adapted to three or four first snap-fit ​​structures 12, are suitable for medium to large-sized devices or high-power scenarios (heavy battery cell weight, high vibration risk). Through multiple sets of corresponding cooperation, radial force is evenly distributed, avoiding structural failure due to excessive load at a single snap-fit ​​point.

[0058] It should be noted that the number of the second snap-fit ​​structure 311 must correspond one-to-one with the number of the first snap-fit ​​structure 12. If there are three first snap-fit ​​structures 12 and only two second snap-fit ​​structures 311, the first snap-fit ​​structure 12 will not have a corresponding groove 3112, and will not be able to form an effective engagement. If there are four second snap-fit ​​structures 311, the extra second snap-fit ​​structures 311 will interfere with other components inside the first cover 31, and will also increase the injection molding cost.
