Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a quick-assembly inner liner structure and a baby bottle machine. Background Technology

[0002] In existing technologies, the assembly structure of the inner liner of baby bottle machines is too complex, which significantly prolongs the assembly time on the production line, increases labor costs and equipment debugging difficulty, reduces mass production efficiency, and makes it difficult to meet market demand for production capacity. Secondly, too many connecting parts and cumbersome assembly steps will increase the assembly error rate, and deviations in a certain link can easily lead to a decrease in the overall structural sealing, resulting in problems such as water leakage and air leakage, which will affect the cleaning and sterilization effect. Utility Model Content

[0003] Therefore, it is necessary to provide a quick-assembly inner liner structure and a bottle machine to address the problem of overly complex assembly structure of the inner liner of the bottle machine.

[0004] A quick-assembly inner liner structure includes: a bottom shell assembly; a middle shell, one end of which is detachably attached to the bottom shell assembly; an inner shell assembly; and an outer shell assembly. The outer shell assembly has a second mounting space, the inner shell assembly is engaged with the outer shell assembly and is at least partially located within the second mounting space, and the end of the middle shell assembly away from the bottom shell assembly is sandwiched between the inner shell assembly and the outer shell assembly and located within the second mounting space. The bottom shell assembly, the middle shell assembly, and the outer shell assembly cooperate to form a cleaning space.

[0005] The above discloses a quick-assembly inner liner structure for use in baby bottle dispensers. The inner liner structure, through the coordinated operation of the bottom shell assembly, intermediate shell, inner shell assembly, and outer shell assembly, demonstrates multiple practical benefits. In terms of assembly efficiency, the components employ detachable connections and clamping / clamping mechanisms, eliminating numerous complex fastening processes, enabling rapid assembly, significantly shortening the production cycle, improving mass production efficiency, and reducing labor costs. Regarding structural stability, one end of the intermediate shell is detachably connected to the bottom shell assembly, while the other end is clamped and fixed by the inner and outer shell assemblies. The inner shell assembly is clamped into the second installation space of the outer shell assembly, forming a multi-positioning stable structure that effectively disperses external forces and vibrations during use, preventing component loosening and ensuring the overall structural durability. The cleaning space formed by the bottom shell assembly, intermediate shell, and outer shell assembly provides an independent and enclosed working area for cleaning and sterilizing baby bottles. It can centrally accommodate cleaning media (such as hot water and steam), improving cleaning efficiency while reducing media leakage, maintaining stable internal pressure, and ensuring that cleaning and sterilization effects meet standards. In addition, the detachable structure design facilitates disassembly, cleaning, and maintenance, thoroughly eliminating hygiene dead spots in the cleaning space, reducing the risk of bacterial growth, meeting the high requirements of hygiene and safety for baby bottle machines, and also facilitating component replacement, extending the service life of the equipment, and taking into account production efficiency, performance, and safety.

[0006] In one embodiment, the bottom shell assembly includes a main shell and multiple limiting blocks. These limiting blocks are circumferentially spaced around the inner side of the main shell, and cooperate with the main shell to form the first mounting space. One end of the intermediate shell is detachable from the main shell and extends into the first mounting space. By circumferentially spaced the multiple limiting blocks around the inner side of the main shell to form the first mounting space, the intermediate shell is effectively limited. The circumferentially distributed limiting blocks can constrain the end of the intermediate shell placed in the first mounting space from multiple directions, effectively preventing radial displacement or shaking of the intermediate shell during assembly and use, ensuring accurate and stable connection between the intermediate shell and the main shell. The spacing of the limiting blocks also reduces the contact area with the intermediate shell without affecting the positioning effect, reducing frictional resistance during assembly and making the assembly and disassembly of the intermediate shell smoother. This structure not only enhances the morphological stability of the first installation space, but also further improves the robustness of the connection between the intermediate shell and the bottom shell assembly through multi-point coordinated limiting, laying a solid foundation for the stress balance of the entire inner shell structure, and indirectly ensuring the stability of the clamping and cooperation between the other end of the intermediate shell and the inner shell assembly and the outer shell assembly.

[0007] In one embodiment, the main housing includes a base and sidewalls. The sidewalls are disposed on the base and surround the outer side of the base. A plurality of limiting blocks are circumferentially spaced around the inner side of the base. The sidewalls and the plurality of limiting blocks are opposite to each other. The base, the sidewalls, and the plurality of limiting blocks cooperate to form the first installation space. The intermediate housing is detachable from the base. By using the base as the basic load-bearing component of the main housing, not only is a direct detachable installation reference surface provided for one end of the intermediate housing, ensuring the stability of the bottom connection of the intermediate housing, but also a constraint frame is formed by the circumferentially distributed limiting blocks on the inner side. This layout allows the end of the intermediate housing to be axially fixed by the base and to avoid radial displacement by the multi-point limiting of the limiting blocks. This dual positioning enhances the accuracy of the intermediate housing installation. The sidewalls are disposed on the outer side of the base and opposite to the limiting blocks, forming the outer protective structure of the first installation space. Its relative arrangement with the limiting block creates a ring-shaped protective zone around the end of the intermediate shell. This not only buffers the impact of external shocks on the intermediate shell but also limits its displacement through its cooperation with the limiting block, preventing shell tilting due to assembly errors or external forces. The base, sidewalls, and limiting block are integrally molded, eliminating connection gaps and assembly stresses between components, forming a continuous and unified load-bearing structure. Compared to a split assembly structure, this design can more evenly distribute the load and external impact transmitted by the intermediate shell, preventing structural failure due to loose or broken connection points, and significantly improving the deformation resistance and overall stability of the main shell and limiting block.

[0008] In one embodiment, the inner shell assembly includes an inner shell body disposed on the outer shell assembly and at least partially located within the second mounting space. By disposing the inner shell body on the outer shell assembly and partially located within the second mounting space, the inner shell body and the outer shell assembly are connected, providing a stable upper frame for the entire inner liner. Its positioning within the second mounting space forms a mutually restraining force system with the intermediate shell and bottom shell assemblies, enhancing the tightness of the connection between the components and preventing loosening due to vibration or other factors during use.

[0009] In one embodiment, the inner shell assembly further includes multiple latches, which are spaced apart circumferentially along the outer side of the inner shell body. The outer shell assembly has multiple third mounting spaces, and the multiple latches abut against the outer shell assembly and correspond one-to-one with each of the multiple third mounting spaces. The multiple latches, spaced apart circumferentially along the outer side of the inner shell body and corresponding to and abutting the third mounting spaces of the outer shell assembly, primarily serve to achieve precise positioning, stable connection, and force balance. From a positioning perspective, the circumferentially distributed latches and their corresponding engagement with the third mounting spaces strictly limit the circumferential rotation and radial offset of the inner shell body within the outer shell assembly, ensuring the precise position of the inner shell body in the second mounting space. This provides a stable reference for the clamping and fixing of the intermediate shell end, preventing assembly misalignment from affecting the overall structural sealing.

[0010] In one embodiment, the inner shell assembly further includes multiple support blocks, which are spaced circumferentially along the outer side of the inner shell body. These support blocks abut against the outer shell assembly, and the end of the intermediate shell, away from the bottom shell assembly, is clamped between the inner shell body and the outer shell assembly. By circumferentially spaced multiple latches along one side of the inner shell body, with each latch abutting against the outer shell assembly and corresponding to a third mounting space, a circumferentially distributed locking structure is formed. This restricts the circumferential rotation of the inner shell body relative to the outer shell assembly and compensates for assembly errors through the elastic deformation of the latches, ensuring the positioning accuracy of the inner shell assembly within the outer shell assembly. This locking mechanism eliminates the need for additional fasteners, simplifying the assembly process and providing cushioning against external impacts, thus enhancing the structure's vibration resistance. The inner shell body, as the main frame of the inner shell assembly, not only serves as the mounting carrier for the latches and support blocks but also bears the core function of forming the clamping space with the outer shell assembly. It is positioned in the second mounting space of the outer shell assembly, clamping the other end of the intermediate shell together with the outer shell assembly. Through surface contact clamping, it disperses the force on the end of the intermediate shell, preventing deformation caused by excessive local pressure, while ensuring the precise positioning of the intermediate shell, laying the foundation for the stability of the overall structure. The core function of the support block is to precisely control the assembly position of the inner shell assembly and the outer shell assembly through abutment and engagement with the outer shell assembly, forming a reliable limiting mechanism. When the inner shell assembly is assembled to the outer shell assembly, the characteristic of multiple support blocks being circumferentially spaced along the side of the inner shell body allows them to simultaneously contact the outer shell assembly during the assembly process. As assembly progresses, the contact force between the support blocks and the outer shell assembly gradually increases. When all support blocks are tightly abutting the outer shell assembly, it clearly indicates that the inner shell assembly has reached the preset assembly position, avoiding loosening due to shallow assembly or deformation of components due to excessive depth, providing a direct basis for judging the proper position during assembly.

[0011] In one embodiment, the outer shell assembly includes a first outer shell and a second outer shell. The second outer shell is disposed on the first outer shell, and the two cooperate to form a second mounting space. The second outer shell has multiple third mounting spaces, which are arranged circumferentially along the sidewalls of the second outer shell. The inner shell assembly is snapped into the multiple third mounting spaces. By using the first outer shell as the basic structure of the outer shell assembly, a stable mounting carrier is provided for the second outer shell. The second mounting space formed by the two becomes the core accommodating area at the other end of the inner shell body and the intermediate shell. The sealing and dimensional adaptability of this space ensures that the inner shell assembly and the intermediate shell maintain relative positional stability after assembly, avoiding component displacement due to external impact. The second outer shell not only serves as the main support for the third mounting spaces but also strengthens the overall rigidity of the outer shell assembly through its combination with the first outer shell. The multiple third mounting spaces arranged circumferentially on its sidewalls correspond one-to-one with the snaps of the inner shell assembly, forming a circumferentially distributed snap-fit ​​structure. This correspondence provides precise assembly positioning points for the snap-fit, restricting the circumferential rotation of the inner shell assembly through the engagement of the snap-fit ​​with the third mounting space. Furthermore, the synergistic effect of multiple locking points disperses the stress between the inner and outer shell assemblies, preventing damage to a single connection point due to excessive load. The second outer shell, in conjunction with the inner shell body, clamps the other end of the intermediate shell. Its smooth inner wall forms a stable clamping surface with the inner shell body, ensuring the intermediate shell is firmly fixed within the second mounting space, further enhancing the overall structural stability.

[0012] In one embodiment, the second outer shell includes a second outer shell body and mating components. Multiple mating components are spaced circumferentially along the second outer shell body. The inner shell assembly is disposed on the second outer shell body and / or the mating components. The end of the intermediate shell away from the bottom shell assembly is sandwiched between the inner shell assembly and the first outer shell. The mating components have the third mounting space. By using the second outer shell body as the main frame of the second outer shell, a circumferentially spaced mounting base is provided for the mating components, simultaneously forming a basic assembly support surface with the inner shell assembly. Together with the mating components, they support the installation requirements of the inner shell assembly, enabling the inner shell assembly to obtain large-area stable support from the second outer shell body and achieve local positioning through precise mating with the mating components, thus improving the overall robustness of the inner shell assembly. The multiple mating components spaced circumferentially along the second outer shell body have the core function of forming a one-to-one snap-fit ​​structure with the inner shell assembly's latches through their own third mounting spaces. This distributed locking point layout allows the buckle to fit the third installation space more closely with the circumferential force characteristics. Each mating part independently bears the local locking force, avoiding structural deformation caused by concentrated force. At the same time, the spaced distribution achieves multiple restrictions on the circumferential rotation of the locking assembly, strengthening the circumferential fixing effect.

[0013] In one embodiment, the second outer shell body and the plurality of mating parts are integrally formed. By adopting an integral molding design for the second outer shell body and the plurality of mating parts, the connection gaps between the second outer shell body and the mating parts are eliminated, making the two form a continuous and complete stress-bearing whole. This design allows the mating parts to uniformly transfer stress to the second outer shell body when bearing the snapping force of the inner shell assembly, avoiding the problem of loosening or breakage of the mating parts due to insufficient strength at the connection points in the split structure. In particular, it can withstand the circumferential constraint force generated when the inner shell assembly and the outer shell assembly are assembled, greatly enhancing the deformation resistance of the second shell and providing a solid foundation for the stability of the overall structure.

[0014] In one embodiment, the first and second outer shells are integrally molded. By adopting an integral molding design for the first and second outer shells, a seamless, integrated structure is formed, significantly improving the impact and deformation resistance of the shell assembly. Compared to a split connection, this design avoids the problem of reduced overall rigidity due to assembly gaps or insufficient strength at connection points. It can more stably support the weight of internal components such as the inner shell assembly and intermediate shell, as well as the forces generated during operation, providing a solid external support frame for the entire inner liner structure.

[0015] In one embodiment, a seal is further included, sandwiched between the intermediate housing and the outer housing assembly, surrounding the intermediate housing and / or the outer housing assembly, and located within the second mounting space. By sandwiching the seal between and surrounding the intermediate housing and the outer housing assembly, it performs a crucial sealing and protective function within the second mounting space. The seal effectively fills the assembly gap between the intermediate housing and the outer housing assembly. Since minor errors inevitably exist during the processing and assembly of components, gaps may appear in direct fit. The seal, through its elastic deformation, tightly conforms to the contact surfaces of the intermediate housing and the outer housing assembly, forming an annular sealing barrier to prevent the cleaning medium within the cleaning space from leaking through the gaps. The seal surrounding the intermediate housing and the outer housing assembly prevents external dust and impurities from entering the second mounting space and the cleaning space, reducing the erosion of the internal structure by contaminants and lowering the risk of equipment failure. Simultaneously, its isolation effect avoids frictional wear caused by direct contact between the intermediate housing and the outer housing assembly, extending the service life of components and ensuring the stability of the overall structure.

[0016] In one embodiment, the intermediate shell includes an intermediate shell body and a folded portion. The intermediate shell body is detachably mounted on the bottom shell assembly. The folded portion is mounted on the intermediate shell body and located at the end of the intermediate shell body away from the bottom shell assembly. The sealing element is sandwiched between the folded portion and the outer shell assembly. The inner shell assembly abuts against both the intermediate shell body and the folded portion. By utilizing the intermediate shell body as the core frame of the intermediate shell, it undertakes the function of detachable connection with the bottom shell assembly. Through a stable installation relationship, it provides an axial positioning foundation for the entire intermediate shell. At the same time, its own structure constitutes the lateral boundary of the cleaning space, ensuring that the cleaning medium flows within a preset range. In addition, the intermediate shell body abuts against the inner shell assembly, forming a radial support point, which can offset the lateral forces generated by the inner shell assembly during assembly and use, preventing the intermediate shell from tilting due to uneven force, and ensuring the verticality and stability of the overall structure. The folded section provides a suitable mounting carrier for the seal. When the seal is clamped between the folded section and the outer shell assembly, the flat contact surface of the folded section ensures that the seal is evenly stressed. Through its own deformation, it tightly fits the outer shell assembly, enhancing the sealing performance of the cleaning space and effectively preventing the leakage of media such as steam and hot water, thus ensuring cleaning and disinfection efficiency. On the other hand, the folded section abuts against the inner shell assembly, forming a double support structure with the intermediate shell body, further restricting the axial displacement of the inner shell assembly and ensuring its precise positioning within the outer shell assembly. At the same time, the abutment with the inner shell assembly disperses the clamping force, preventing the intermediate shell body from deforming due to excessive local stress.

[0017] The second aspect of this application discloses a baby bottle machine, which includes: the aforementioned quick-assembly inner liner structure; and a baby bottle machine body, wherein the quick-assembly inner liner structure is disposed on the baby bottle machine body.

[0018] The second aspect disclosed above discloses a baby bottle machine in which a quick-assembly inner liner structure is set on the main body of the baby bottle machine, simplifying the assembly process of the whole machine. The connection methods such as snap-fit ​​and clamping of the various components of the inner liner can be quickly connected with the preset installation position of the main body, and fixation can be completed without complicated procedures. This not only reduces the labor cost of the whole machine production, but also ensures the relative positional accuracy of the inner liner and the main body through standardized assembly dimensions, avoiding the impact of installation deviation on the function.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] The following describes, with reference to the accompanying drawings, some embodiments of the quick-assembly inner liner structure and baby bottle machine of this utility model.

[0044] Example 1

[0045] like Figures 1 to 16 As shown, this embodiment discloses a quick-assembly inner liner structure, including: a bottom shell assembly 1; a middle shell 2, one end of which is detachably mounted to the bottom shell assembly 1; an inner shell assembly 3; and an outer shell assembly 4. The outer shell assembly 4 is provided with a second mounting space 401. The inner shell assembly 3 is engaged with the outer shell assembly 4 and is at least partially located in the second mounting space 401. The end of the middle shell 2 away from the bottom shell assembly 1 is sandwiched between the inner shell assembly 2 and the outer shell assembly 4 and is located in the second mounting space 401. The bottom shell assembly 1, the middle shell 2, and the outer shell assembly 4 cooperate to form a cleaning space 201.

[0046] This application discloses a quick-assembly inner liner structure for use in a baby bottle dispenser. The inner liner structure, through the coordinated cooperation of the bottom shell assembly 1, the intermediate shell 2, the inner shell assembly 3, and the outer shell assembly 4, exhibits multiple practical benefits. In terms of assembly efficiency, the components employ detachable connections and clamping / clamping mechanisms, eliminating numerous complex fastening processes, enabling rapid assembly, significantly shortening the production cycle, improving mass production efficiency, and reducing labor costs. Regarding structural stability, one end of the intermediate shell 2 is detachably connected to the bottom shell assembly 1, while the other end is clamped and fixed by the inner shell assembly 3 and the outer shell assembly 4. The inner shell assembly 3 is clamped into the second mounting space 401 of the outer shell assembly 4, forming a multi-positioning stable structure that effectively disperses external forces and vibrations during use, preventing component loosening and ensuring the overall structural durability. The cleaning space 201 formed by the bottom shell assembly 1, the intermediate shell 2, and the outer shell assembly 4 provides an independent and enclosed working area for cleaning and sterilizing baby bottles. It can centrally contain the cleaning medium, improving cleaning efficiency while reducing medium leakage, maintaining stable internal pressure, and ensuring that the cleaning and sterilization effects meet standards. In addition, the detachable structure design facilitates disassembly, cleaning, and maintenance, thoroughly eliminating hygiene dead spots in the cleaning space, reducing the risk of bacterial growth, meeting the high requirements of hygiene and safety for baby bottle machines, and also facilitating component replacement, extending the service life of the equipment, and taking into account production efficiency, performance, and safety.

[0047] like Figure 2 , Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom shell assembly 1 includes a main shell 11 and limiting blocks 12. The number of limiting blocks 12 is multiple, and the multiple limiting blocks 12 are circumferentially spaced around the inner side of the main shell 11. The multiple limiting blocks 12 cooperate with the main shell 11 to form a first mounting space 101. One end of the intermediate shell 2 is detachable from the main shell 11 and extends into the first mounting space 101. By circumferentially spaced around the inner side of the main shell 11 and cooperating with the main shell 11 to form the first mounting space 101, the intermediate shell 2 is effectively limited. The circumferentially distributed limiting blocks 12 can constrain the end of the intermediate shell 2 placed in the first mounting space 101 from multiple directions, effectively preventing radial displacement or shaking of the intermediate shell 2 during assembly and use, and ensuring accurate and stable connection between the intermediate shell 2 and the main shell 11. The spacing of the limiting blocks 12 can reduce the contact area with the intermediate shell 2 without affecting the positioning effect, thereby reducing frictional resistance during assembly and making the disassembly and assembly of the intermediate shell 2 smoother. This structure not only enhances the morphological stability of the first installation space 101, but also further improves the firmness of the connection between the intermediate shell 2 and the bottom shell assembly 1 through multi-point coordinated limiting, laying a solid foundation for the force balance of the entire inner liner structure, and indirectly ensuring the stability of the clamping and cooperation between the other end of the intermediate shell 2 and the inner shell assembly 3 and the outer shell assembly 4.

[0048] like Figure 3 , Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines: the main housing 11 includes a base 111 and a side wall 112. The side wall 112 is disposed on the base 111 and surrounds the outer side of the base 111. A plurality of limiting blocks 12 are arranged circumferentially around the inner side of the base 111. The side wall 112 and the plurality of limiting blocks 12 are arranged opposite to each other. The base 111, the side wall 112 and the plurality of limiting blocks 12 cooperate to form a first installation space 101. The intermediate housing 2 is detachable from the base 111. By using the base 111 as the basic load-bearing component of the main housing, not only is a direct detachable installation reference surface provided for one end of the intermediate housing 2, ensuring the stability of the bottom connection of the intermediate housing 2, but also a constraint frame is formed by the circumferentially distributed limiting blocks 12 on the inner side. This layout allows the end of the intermediate housing 2 to be axially fixed by the base 111, and radial offset to be avoided by the multi-point limiting of the limiting blocks 12. The dual positioning enhances the installation accuracy of the intermediate housing 2. The side wall 112 is located outside the base 111 and is positioned opposite to the limiting block 12, forming the outer protective structure of the first installation space 101. Its relative arrangement with the limiting block 12 creates a ring-shaped protective zone around the end of the intermediate shell 2, which not only buffers the impact of external impacts on the intermediate shell 2 but also limits the displacement of the intermediate shell 2 through its cooperation with the limiting block 12, preventing shell tilting due to assembly errors or external forces. The base 111, side wall 112, and limiting block 12 are integrally molded, eliminating connection gaps and assembly stress between components, making them a continuous and unified force-bearing whole. Compared to a split assembly structure, this design can more evenly distribute the load and external impact transmitted by the intermediate shell 2, avoiding structural failure due to loose or broken connection points, and significantly improving the deformation resistance and overall stability of the main shell 11 and the limiting block 12.

[0049] like Figures 8 to 16As shown, in addition to the features of the above embodiments, this embodiment further defines: the inner shell assembly 3 includes an inner shell body 31, a buckle 32 and a support block 33. There are multiple buckles 32, which are spaced apart along the outer circumferential side of the inner shell body 31. There are multiple support blocks 33, which are spaced apart along the outer circumferential side of the inner shell body 31. The inner shell body 31 is disposed on the outer shell assembly 4 and located in the second mounting space 401. The outer shell assembly 4 is provided with multiple third mounting spaces 402. The multiple buckles 32 abut against the outer shell assembly 4 and correspond one-to-one with the multiple third mounting spaces 402. The multiple support blocks 33 abut against the outer shell assembly 4. The end of the intermediate shell 2 away from the bottom shell assembly 1 is sandwiched between the inner shell body 31 and the outer shell assembly 4. By circumferentially spacing multiple latches 32 along one side of the inner shell body 31, the latches 32 abut against the outer shell assembly 4 and correspond one-to-one with the third mounting space 402, forming a circumferentially distributed locking structure. This not only restricts the circumferential rotation of the inner shell body 31 relative to the outer shell assembly 4, but also compensates for assembly errors through the elastic deformation of the latches 32, ensuring the positioning accuracy of the inner shell assembly 3 within the outer shell assembly 4. This locking mechanism eliminates the need for additional fasteners, simplifying the assembly process and providing a certain buffer when subjected to external impacts, thus enhancing the structure's vibration resistance. The inner shell body 31, as the main frame of the inner shell assembly 3, not only serves as the mounting carrier for the latches 32 and support blocks 33, but also bears the core function of forming a clamping space with the outer shell assembly 4. Set in the second mounting space 401 of the outer shell assembly 4, it clamps the other end of the intermediate shell 2 together with the outer shell assembly 4. Through surface contact clamping, it disperses the force on the end of the intermediate shell 2, avoiding deformation caused by excessive local pressure, while ensuring the precise positioning of the intermediate shell 2, laying the foundation for the stability of the overall structure. The core function of the support block 33 is to precisely control the assembly position of the inner shell assembly 3 and the outer shell assembly 4 through its abutting contact with the outer shell assembly 4, forming a reliable limiting mechanism. When the inner shell assembly 3 is assembled to the outer shell assembly 4, the circumferentially spaced distribution of multiple support blocks 33 along the side of the inner shell body 31 allows them to simultaneously contact the outer shell assembly 4 during assembly. As assembly progresses, the contact force between the support blocks 33 and the outer shell assembly 4 gradually increases. When all support blocks 33 are tightly abutting the outer shell assembly 4, it clearly indicates that the inner shell assembly 3 has reached the preset assembly position, preventing loosening due to shallow assembly or deformation due to excessive depth, providing a direct and intuitive basis for judging the assembly position.

[0050] like Figures 10 to 13As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner shell assembly 3 includes an inner shell body 31, which is disposed on the outer shell assembly 4 and at least partially located in the second mounting space 401. By disposing the inner shell body 31 on the outer shell assembly 4 and partially located in the second mounting space 401, the connection between the inner shell body 31 and the outer shell assembly 4 is achieved, providing a stable upper frame for the inner liner as a whole. Its positioning in the second mounting space 401 can form a mutually restraining force system with the intermediate shell 2 and the bottom shell assembly 1, enhancing the tightness of the connection between the components and preventing loosening due to vibration and other factors during use.

[0051] like Figures 10 to 13 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner shell assembly 3 also includes multiple snap fasteners 32, which are spaced apart circumferentially along the outer side of the inner shell body 31. The outer shell assembly 4 is provided with multiple third mounting spaces 402, and the multiple snap fasteners 32 abut against the outer shell assembly 4 and correspond one-to-one with the multiple third mounting spaces 402. By having multiple snap fasteners 32 spaced apart circumferentially along the outer side of the inner shell body 31 and corresponding one-to-one with the third mounting spaces 402 of the outer shell assembly 4, the main functions are to accurately position, securely connect, and balance forces. From a positioning perspective, the corresponding engagement of the circumferentially distributed snap fasteners 32 with the third mounting spaces 402 can strictly limit the circumferential rotation and radial displacement of the inner shell body 31 within the outer shell assembly 4, ensuring the accurate position of the inner shell body 31 in the second mounting space 401, providing a stable reference for the clamping and fixing of the end of the intermediate shell 2, and avoiding the impact of assembly misalignment on the overall structural sealing.

[0052] like Figures 10 to 13As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner shell assembly 3 also includes support blocks 33, and there are multiple support blocks 33. The multiple support blocks 33 are arranged circumferentially along the outer side of the inner shell body 31, and the multiple support blocks 33 abut against the outer shell assembly 4. The end of the intermediate shell 2 away from the bottom shell assembly 1 is sandwiched between the inner shell body 31 and the outer shell assembly 4. By using the first outer shell 41 as the basic structure of the outer shell assembly 4, a stable mounting carrier is provided for the second outer shell 42. The second mounting space 401 formed by the two becomes the core accommodating area of ​​the other end of the inner shell body 31 and the intermediate shell 2. The sealing and dimensional adaptability of this space ensures that the inner shell assembly 3 and the intermediate shell 2 can maintain the stability of their relative positions after assembly, avoiding component displacement caused by external impact. The second outer shell 42 is not only the main bearing body of the third mounting space 402, but also strengthens the overall rigidity of the outer shell assembly through its combination with the first outer shell 41. Multiple third mounting spaces 402 arranged circumferentially on its sidewalls correspond one-to-one with the snap fasteners 32 of the inner shell assembly 3, forming a circumferentially distributed snap-fit ​​structure. This correspondence provides precise assembly positioning points for the snap fasteners 32, restricting the circumferential rotation of the inner shell assembly 3 through the engagement of the snap fasteners 32 with the third mounting spaces 402. Furthermore, the synergistic effect of multiple snap points disperses the force between the inner shell assembly 3 and the outer shell assembly 4, preventing damage to a single connection point due to excessive load. The second outer shell 42, in conjunction with the inner shell body 31, clamps the other end of the intermediate shell 2. Its flat inner wall forms a stable clamping surface with the inner shell body 31, ensuring that the intermediate shell 2 is firmly fixed within the second mounting spaces 401, further enhancing the overall structural stability.

[0053] like Figures 10 to 16As shown, in addition to the features of the above embodiments, this embodiment further defines: the second outer shell 42 includes a second outer shell body 421 and mating parts 422. There are multiple mating parts 422, which are spaced apart circumferentially along the second outer shell body 421. The inner shell assembly 3 is disposed on the second outer shell body 421 and / or the mating parts 422. The end of the intermediate shell 2 away from the bottom shell assembly 1 is sandwiched between the inner shell assembly 3 and the first outer shell 41. The mating parts 422 are provided with a third mounting space 402. By using the second outer shell body 421 as the main frame of the second outer shell 42, a circumferentially spaced mounting base is provided for the mating parts 422, while simultaneously forming a basic assembly support surface with the inner shell assembly 3. Together with the mating parts 422, they bear the installation requirements of the inner shell assembly 3, enabling the inner shell assembly 3 to obtain large-area stable support by relying on the second outer shell body 421, and to achieve local positioning through precise mating with the mating parts 422, thereby improving the overall robustness of the inner shell assembly 3. Multiple mating parts 422 are spaced apart circumferentially along the second outer shell body 421. Their core function is to form a one-to-one locking structure with the buckles 32 of the inner shell assembly 3 through their own third mounting space 402. This distributed locking point layout makes the fit between the buckles 32 and the third mounting space 402 more in line with the circumferential force characteristics. Each mating part 422 independently bears the local locking force, avoiding structural deformation caused by concentrated force. At the same time, the spaced distribution achieves multiple restrictions on the circumferential rotation of the shell assembly 3, strengthening the circumferential fixing effect.

[0054] like Figure 14 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second outer shell body 421 and the plurality of mating parts 422 are integrally formed. By adopting an integral forming design for the second outer shell body 421 and the plurality of mating parts 422, the connection gap between the second outer shell body 421 and the mating parts 422 is eliminated, making the two form a continuous and complete force-bearing whole. This design allows the mating parts 422 to uniformly transfer stress to the second outer shell body 421 when bearing the snap-fit ​​force of the inner shell assembly 3, avoiding the problem of loosening or breakage of the mating parts 422 due to insufficient strength of the connection points in the split structure. In particular, it can withstand the circumferential constraint force generated when the inner shell assembly 3 and the outer shell assembly 4 are assembled, greatly enhancing the deformation resistance of the second outer shell 42 and providing a solid foundation for the stability of the overall structure.

[0055] like Figure 12As shown, in addition to the features of the above embodiments, this embodiment further specifies that the first outer shell 41 and the second outer shell 42 are integrally formed. By adopting an integral forming design for the first outer shell 41 and the second outer shell 42, the two form a seamless integral structure, which greatly improves the impact resistance and deformation resistance of the outer shell assembly 4. Compared with a split connection, this design avoids the problem of reduced overall rigidity caused by insufficient assembly gaps or connection point strength, and can more stably bear the weight of internal components such as the inner shell assembly 3 and the intermediate shell 2, as well as the forces generated during operation, providing a solid external support frame for the entire inner liner structure.

[0056] like Figure 2 , Figure 12 , Figure 13 , Figure 15 and Figure 16 As shown, in addition to the features of the above embodiments, this embodiment further includes a sealing element 5, which is sandwiched between the intermediate housing 2 and the outer housing assembly 4, and surrounds the intermediate housing 2 and / or the outer housing assembly 4. The sealing element 5 is located in the second mounting space 401. By sandwiching the sealing element 5 between the intermediate housing 2 and the outer housing assembly 4 and surrounding both, it performs a crucial sealing and protection function in the second mounting space 401. The sealing element 5 effectively fills the assembly gap between the intermediate housing 2 and the outer housing assembly 4. Since minor errors inevitably exist in the processing and assembly of each component, gaps may appear in direct fit. The sealing element 5, through its own elastic deformation, tightly fits the contact surface of the intermediate housing 2 and the outer housing assembly 4, forming an annular sealing barrier to prevent the cleaning medium in the cleaning space 201 from leaking out of the gap. The sealing element 5, surrounding the intermediate housing 2 and the outer housing assembly 4, can prevent external dust and impurities from entering the second mounting space 401 and the cleaning space 201, reducing the erosion of the internal structure by contaminants and lowering the risk of equipment failure. At the same time, its isolation function can prevent friction and wear caused by direct contact between the intermediate shell 2 and the outer shell assembly 4, extend the service life of the components, and ensure the stability of the overall structure.

[0057] like Figure 6 , Figure 15 and Figure 16As shown, the intermediate shell 2 includes an intermediate shell body 21 and a folding portion 22. The intermediate shell body 21 is detachably mounted on the bottom shell assembly 1. The folding portion 22 is mounted on the intermediate shell body 21 and located at the end of the intermediate shell body 21 away from the bottom shell assembly 1. A sealing member 5 is sandwiched between the folding portion 22 and the outer shell assembly 4. The inner shell assembly 3 abuts against the intermediate shell body 21 and the folding portion 22 respectively. By utilizing the intermediate shell body 21 as the core frame of the intermediate shell 2, it undertakes the function of detachable connection with the bottom shell assembly 1. Through a stable installation relationship, it provides an axial positioning foundation for the entire intermediate shell 2. At the same time, its own structure constitutes the lateral boundary of the cleaning space 201, ensuring that the cleaning medium flows within a preset range. In addition, the intermediate shell body 21 abuts against the inner shell assembly 3, forming a radial support point, which can offset the lateral force generated by the inner shell assembly 3 during assembly and use, preventing the intermediate shell 2 from tilting due to uneven force, and ensuring the verticality and stability of the overall structure. The folding portion 21 provides a suitable mounting carrier for the seal 5. When the seal 5 is clamped between the folding portion 21 and the outer shell assembly 4, the flat contact surface of the folding portion 21 ensures that the seal 5 is evenly stressed. Through its own deformation, it tightly fits the outer shell assembly 4, enhancing the sealing performance of the cleaning space 201 and effectively preventing the leakage of media such as steam and hot water, thus ensuring cleaning and disinfection efficiency. On the other hand, the folding portion 22 abuts against the inner shell assembly 3, forming a double support structure with the intermediate shell body 21, further restricting the axial displacement of the inner shell assembly 3 and ensuring the accurate positioning of the inner shell assembly 3 in the outer shell assembly 4. At the same time, by abutting against the inner shell assembly 2, it disperses the clamping force, preventing the intermediate shell body 21 from deforming due to excessive local stress.

[0060] The second aspect of this application discloses a baby bottle dispenser that incorporates a quick-assembly inner liner structure onto the dispenser body, simplifying the overall assembly process.

This reduces labor costs in the overall production process and ensures the relative positional accuracy between the inner liner and the body through standardized assembly dimensions, preventing functional issues caused by installation deviations.
