Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a mold preparation and preparation apparatus. Background Technology

[0002] This section is intended to provide background or context for embodiments of this application. The description herein is not intended to imply that it is prior art simply because it is included in this section.

[0003] In related technologies, the product segment of aerosol-generated products has a single-layer structure. With the increasing diversification of consumer demands, traditional single-layer product segments can no longer meet market needs. Therefore, how to produce double-layer product segments is an important research direction in this field. Utility Model Content

[0004] In view of this, the present application aims to provide a mold and apparatus for preparing a double-layered product segment.

[0005] The first aspect of this application provides a mold preparation method, including:

[0006] The outer mold forms a receiving cavity;

[0007] An inner mold, at least a portion of which is disposed within the receiving cavity, a first extrusion channel is formed inside the inner mold, and a second extrusion channel is defined between the outer periphery of at least a portion of the inner mold and the cavity wall of the receiving cavity, the first extrusion channel being used to extrude the inner matrix of the product segment, and the second extrusion channel being used to extrude the outer layer of the product segment.

[0008] In some embodiments, the inner mold forms a first feed port on a first side along a first direction, and the inner mold forms a first discharge port on a second side along a first direction, the first feed port and the first discharge port being connected through the first extrusion channel;

[0009] The outer mold has a second feed port on its circumferential surface and a second discharge port on its second side along the first direction. The second feed port and the second discharge port are connected through the second extrusion channel.

[0010] In some embodiments, the end face of the inner mold facing the second side is flush with the end face of the outer mold facing the second side.

[0011] In some embodiments, the inner mold is located within the receiving cavity on a first side along a first direction, and the outer mold forms a clearance opening on a first side along the first direction, the clearance opening being connected to the first feed port.

[0012] In some embodiments, at least one of the circumferential surface of the first extrusion channel and the outer circumferential surface of the inner mold has a shaping structure for forming a protrusion or groove in at least one of the inner matrix and the outer jacket.

[0013] In some embodiments, the first extrusion channel has the shaping structure on a second side along a first direction.

[0014] In some embodiments, the inner mold has the shaping structure on a second side along a first direction.

[0015] In some embodiments, the inner mold has a first limiting platform, and the circumferential surface of the receiving cavity has a second limiting platform. The first limiting platform abuts against the second limiting platform to restrict the movement of the inner mold toward a second side in a first direction.

[0016] In some embodiments, the inner mold includes an annular sleeve and a stop, the annular sleeve forming the first extrusion channel and the stop being disposed within the first extrusion channel.

[0017] In some embodiments, the outer mold is a one-piece molded structure.

[0018] In some embodiments, the inner mold is a one-piece molded structure.

[0019] A second aspect of this application provides a preparation apparatus, including two extruders and a preparation mold as described in any of the preceding claims, wherein one of the two extruders is connected to a first extrusion channel, and the other of the two extruders is connected to a second extrusion channel.

[0020] The preparation mold provided in this application embodiment has two advantages. First, the first extrusion channel and the second extrusion channel are separated from each other, and the materials located in the first extrusion channel and the materials located in the second extrusion channel are separated from each other. This not only improves the production efficiency of each material but also prevents different materials from mixing together. For example, the matrix segment can be made from the product segment, thus preventing any impact on the taste of the aerosol released from the matrix segment. Second, the preparation mold can simultaneously produce the inner matrix and the outer layer. This not only enables the mass production of product segments, improving production efficiency and reducing production costs, but also, when the matrix segment is made from the product segment, allows for the preparation of matrix segments with rich textures, meeting diverse user needs.

[0043] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0044] In the description of the embodiments of this application, the "first direction" orientation or positional relationship is based on Figures 1 to 3 , Figure 10 The orientation or positional relationship shown, the "top and bottom" orientation or positional relationship is based on Figure 6 The orientation or positional relationship shown is for illustrative purposes only and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of this application.

[0045] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features / embodiments can form different implementation methods. To avoid unnecessary repetition, the various possible combinations of various specific technical features / embodiments in this application will not be described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] It should be noted that in this application, the first side of the first direction and the second side of the first direction are two opposite directions. "Multiple" refers to a quantity including two or more.

[0047] To facilitate understanding of the preparation mold 10 provided in the embodiments of this application, the aerosol-generating article 200 prepared using the preparation mold 10 provided in the embodiments of this application will be described as follows:

[0048] The preparation mold 10 can be used to prepare at least a portion of the structure of the aerosol generating article 200. For example, a portion of the aerosol generating article 200 can be made by the preparation mold 10, or the entire aerosol generating article 200 can be made by the preparation mold 10.

[0049] Please see Figure 1The product segment 210 includes an inner substrate 211 and an outer layer 212. The outer layer 212 surrounds the outer periphery of the inner substrate 211. The inner substrate 211 has a first circumferential surface 211a facing the outer layer 212, and the outer layer 212 has a second circumferential surface 212a facing the inner substrate 211. At least a portion of the first circumferential surface 211a and the second circumferential surface 212a are in a stop-and-go fit.

[0050] For example, a portion of the first circumferential surface 211a may be in a stop-and-go fit with the entire second circumferential surface 212a; or, the entire first circumferential surface 211a may be in a stop-and-go fit with a portion of the second circumferential surface 212a; or, a portion of the first circumferential surface 211a and a portion of the second circumferential surface 212a may be in a stop-and-go fit. In this way, the inner matrix 211 and the outer layer 212 can exert forces on each other, thereby enhancing the connection stability between the inner matrix 211 and the outer layer 212, making relative rotation between the inner matrix 211 and the outer layer 212 difficult, improving the overall connection strength of the product segment 210, and enhancing connection reliability.

[0051] Please see Figure 10 The aerosol generating article 200 provided in this application embodiment includes a functional segment 240 and a matrix segment 250, and at least one of the matrix segment 250 and the functional segment 240 adopts an article segment 210. That is, the matrix segment 250 may adopt an article segment 210, the functional segment 240 may adopt an article segment 210, or both the matrix segment 250 and the functional segment 240 may adopt an article segment 210.

[0052] As an example, functional segment 240 may provide at least one of the following: filtration function, adsorption function, aroma enhancement function, dilution function, cooling function, and resistance adjustment function.

[0053] Filtration function refers to the function of filtering out at least some of the particulate matter in aerosols.

[0054] Adsorption function refers to the ability to adsorb at least some impurities in aerosols. It can be understood that these impurities are substances that remove the active ingredients from the aerosol; the active ingredients are those that need to be provided to the user.

[0055] The aroma-enhancing function refers to the function of adding aroma-producing components to aerosols.

[0056] The dilution function refers to the function of reducing the concentration of active ingredients in aerosols.

[0057] Cooling function refers to the function of reducing the temperature of aerosols.

[0058] The suction resistance adjustment function refers to the function of reducing or increasing suction resistance. In this way, the flow rate and distribution of aerosols can be controlled, and the suction resistance and aerosol uniformity can be optimized.

[0059] Taking the substrate segment 250 as an example of using the article segment 210, the substrate segment 250 is used to generate aerosols by heating. Exemplarily, the substrate segment 250 can be used to generate aerosols by heating without combustion. That is, the substrate segment 250 is heated below its ignition point to generate aerosols. The substrate segment 250 does not burn during the aerosol generation process. In some applications, the substrate segment 250 can also be used to generate aerosols by ignition. The substrate segment 250 provided in this application embodiment mainly generates aerosols by heating without combustion.

[0060] Both the inner matrix 211 and the outer layer 212 can release aerosols when heated.

[0061] In one embodiment, the matrix segment 250 is made of the article segment 210, and the inner matrix 211 and the outer layer 212 are made of materials with different flavors, so that the matrix segment 250 can produce aerosols with different flavors. For example, at least one component of the inner matrix 211 and the outer layer 212 is different, or the content of at least one component of the inner matrix 211 and the outer layer 212 is different, both of which can produce different flavors.

[0062] In another embodiment, both the inner matrix 211 and the outer layer 212 are made of the same flavored material, thereby enhancing the richness of the aerosol's flavor. For example, all components and amounts of the inner matrix 211 and the outer layer 212 are identical.

[0063] Taking functional segment 240 using article segment 210 as an example, please refer to [link to example]. Figure 10 Functional segment 240 includes a support segment 241, which can withstand the temperature of the aerosol from matrix segment 250 and maintain its shape. The support segment 241 provides support. Thus, through the mating fit between the inner matrix 211 and the outer layer 212, the connection strength of the support segment 241 is improved, thereby providing better support for the matrix segment 250. During the production process of the support segment 241, the inner matrix 211 and the outer layer 212 are firmly connected and not easily separated.

[0064] It is understandable that when the substrate segment 250 adopts the product segment 210, the substrate segment 250 also has good connection strength. During the production process of the substrate segment 250, the inner matrix 211 and the outer layer 212 are firmly connected and not easily separated.

[0065] Please see Figure 2 , Figure 3 , Figures 6 to 8This application provides a preparation mold 10 for preparing a product segment 210 of an aerosol-generating article 200. The preparation mold 10 includes an outer mold 2 and an inner mold 1. The outer mold 2 forms a receiving cavity 21, and at least a portion of the inner mold 1 is disposed within the receiving cavity 21. A first extrusion channel 1a is formed inside the inner mold 1, and a second extrusion channel 2a is defined between the outer periphery of at least a portion of the inner mold 1 and the cavity wall surface of the receiving cavity 21. The first extrusion channel 1a is used to extrude the inner matrix 211 of the product segment 210, and the second extrusion channel 2a is used to extrude the outer layer 212 of the product segment 210.

[0066] In other words, the preparation mold 10 can be used to prepare the inner substrate 211 and the outer layer 212. The outer layer 212 surrounds the outer periphery of the inner substrate 211, so that the preparation mold 10 can produce a double-layered article segment 210, such as a double-layered matrix segment 250 and / or a double-layered functional segment 240.

[0067] Please see Figure 3 The receiving cavity 21 provides installation space for the inner mold 1. At least a portion of the inner mold 1 is located within the receiving cavity 21. The inner mold 1 and the outer mold 2 can be considered as a nested structure, saving space and making the entire preparation mold 10 more compact.

[0068] The inner mold 1 being at least partially disposed within the receiving cavity 21 means that a portion of the inner mold 1 is located within the receiving cavity 21; or, the entire inner mold 1 is located within the receiving cavity 21. For example, a portion of the inner mold 1 may extend out of the receiving cavity 21, thereby facilitating the feeding of material into the first extrusion channel 1a.

[0069] In one embodiment, please refer to Figure 3 In one embodiment, a second extrusion channel 2a is defined between a portion of the outer periphery of the inner mold 1 and the cavity wall of the receiving cavity 21. In another embodiment, the second extrusion channel 2a is defined between the entire outer periphery of the inner mold 1 and the cavity wall of the receiving cavity 21.

[0070] Please see Figure 2 and Figure 3The first extrusion channel 1a is located inside the inner mold 1, and the second extrusion channel 2a surrounds at least a portion of the outer periphery of the inner mold 1. That is, the first extrusion channel 1a and the second extrusion channel 2a are separated from each other. Thus, material located in the first extrusion channel 1a cannot enter the second extrusion channel 2a, and material located in the second extrusion channel 2a cannot enter the first extrusion channel 1a. The inner matrix 211 and the outer layer 212 can be extruded and formed respectively through the first extrusion channel 1a and the second extrusion channel 2a. During this process, the separation of material in the first extrusion channel 1a and the material in the second extrusion channel 2a not only improves their respective production efficiency, but also, when the matrix section 250 uses the product section 210, prevents different materials from mixing together and affecting the taste of the aerosol released by the matrix section 250. After the inner matrix 211 and outer layer 212 are extruded, the inner matrix 211 and outer layer 212 still have softness, and at least part of the first circumferential surface 211a of the inner matrix 211 and the second circumferential surface 212a of the outer layer 212 are in a stop-fitting relationship, and the first circumferential surface 211a and the second circumferential surface 212a are tightly connected as the moisture evaporates during the subsequent drying process.

[0071] Extrusion molding refers to a process in which material is pushed by the screw through the barrel and screw of an extruder 20 and continuously passed through the die head to form products or semi-finished products of various cross-sections. A die 10 is located at the die head, and material continuously passes through the die 10 to form products or semi-finished products of various cross-sections.

[0072] Drying processes are used to reduce the liquid content of extruded or semi-extruded products. Drying processes include, but are not limited to, hot air drying or freeze drying.

[0073] Understandably, after extrusion molding, the extruded material continuously extruded from the preparation mold 10 can be cut into a preset length as needed. The extruded material of the preset length can be dried to obtain the product segment 210 of the target length. Of course, it can also be dried and then sheared a second time to obtain the product segment 210 of the target length.

[0074] The first extrusion channel 1a is used to extrude the inner matrix 211 of the product segment 210, and the second extrusion channel 2a is used to extrude the outer coat layer 212 of the product segment 210. That is, the inner matrix 211 and the outer coat layer 212 are extruded together. Thus, by setting the first extrusion channel 1a and the second extrusion channel 2a, the die 10 can simultaneously produce the inner matrix 211 and the outer coat layer 212. This not only enables mass production of the product segment 210, improving production efficiency and reducing production costs, but also, when the matrix segment 250 uses the product segment 210, allows for the production of a matrix segment 250 with a rich texture, meeting diverse user needs.

[0075] The preparation mold 10 provided in this application embodiment has two aspects. First, the first extrusion channel 1a and the second extrusion channel 2a are separated from each other. The materials located in the first extrusion channel 1a and the materials located in the second extrusion channel 2a are separated from each other. This not only improves the production efficiency of each material but also prevents different materials from mixing together. For example, the matrix segment 250 can use the product segment 210, thus preventing any impact on the taste of the aerosol released by the matrix segment 250. Second, the preparation mold 10 can simultaneously produce the inner matrix 211 and the outer layer 212. This not only enables the mass production of the product segment 210, improving production efficiency and reducing production costs, but also, when the matrix segment 250 uses the product segment 210, allows for the preparation of matrix segments 250 with rich tastes, meeting the diverse needs of users.

[0076] The preparation mold 10 provided in this application embodiment can prepare the product segment 210 through a common continuous extrusion process. The extrusion process can be carried out using the preparation mold 10 provided in this application embodiment and any suitable extruder 20. For example, the extruder 20 can be a hydraulic plunger extruder, a twin-screw extruder, a single-screw extruder, etc.

[0077] In some embodiments, please refer to Figure 3 The outer periphery of the inner mold 1 abuts against the cavity wall of the receiving cavity 21, thereby enhancing the connection stability between the inner mold 1 and the outer mold 2 and preventing the inner mold 1 and the outer mold 2 from loosening or shifting during operation.

[0078] The inner mold 1 and the outer mold 2 can be detachably connected or non-detachably connected.

[0079] In the embodiments of this application, unless otherwise stated, detachable connections include, but are not limited to, snap-fit ​​connections, screw connections, or bolt connections. Non-detachable connections include, but are not limited to, welding or bonding.

[0080] In one embodiment, please refer to Figure 1 and Figure 2 The first extrusion channel 1a is approximately cylindrical, meaning that the inner matrix 211 is approximately cylindrical. The second extrusion channel 2a is approximately annular, meaning that the outer layer 212 is approximately annular.

[0081] In some embodiments, please refer to Figure 3 The inner mold 1 forms a first feed port 1b on a first side along a first direction, and a first discharge port 1c on a second side along a first direction. The first feed port 1b and the first discharge port 1c are connected through a first extrusion channel 1a. That is, the material enters the first extrusion channel 1a through the first feed port 1b, is extruded into an inner matrix 211 in the first extrusion channel, and is then discharged from the first discharge port.

[0082] Please continue reading. Figure 3 The first feed inlet 1b and the first discharge outlet 1c are located on opposite sides of the first extrusion channel 1a, which extends in a straight line along the first direction. In this way, the material can maintain its movement approximately along the first direction during extrusion, which not only reduces the material's resistance and improves production efficiency, but also keeps the inner matrix 211 relatively straight, preventing it from bending and easily breaking, thus improving product quality.

[0083] Please see Figure 2 The outer mold 2 has a second feed port 2b on its circumferential surface and a second discharge port 2c on its second side along the first direction. The second feed port 2b and the second discharge port 2c are connected by a second extrusion channel 2a. That is, the material enters the second extrusion channel 2a through the second feed port 2b, is extruded into an outer jacket layer 212 in the second extrusion channel, and is then discharged from the second discharge port.

[0084] Please continue to refer to section 2 and... Figure 3 The second feed port 2b surrounds the circumferential surface of the first direction. The second feed port 2b and the first feed port 1b are located on different sides of the preparation mold 10, so that the material of the inner substrate 211 and the material of the outer layer 212 can enter the preparation mold 10 from two different directions, thereby avoiding mutual interference during the feeding process. In addition, the first discharge port 1c and the second discharge port 2c are located on the same side of the preparation mold 10, which facilitates the collection of the inner substrate 211 and the outer layer 212 for subsequent processes such as shearing.

[0085] In some embodiments, please refer to Figure 2 and Figure 3 The end face of the inner mold 1 facing the second side is flush with the end face of the outer mold 2 facing the second side. That is, the end faces of the first discharge port 1c and the second discharge port 2c are flush. This ensures that, on the one hand, the end faces of the inner mold 1 and the outer mold 2 facing the second side will not be misaligned, thus preventing the formation of local protrusions 220 that could affect the molding of the inner matrix 211 and the outer layer 212. On the other hand, it ensures that the inner matrix 211 and the outer layer 212 are extruded simultaneously, guaranteeing consistency during extrusion.

[0086] In some embodiments, please refer to Figure 3 The inner mold 1 is located within the receiving cavity 21 along the first side of the first direction, and the outer mold 2 forms a clearance opening 2d along the first side of the first direction, which is connected to the first feed port 1b. In other words, the entire inner mold 1 is located within the receiving cavity 21, which can prevent damage caused by collision between the external structure and the inner mold 1, and the outer mold 2 provides good protection for the inner mold 1.

[0087] Please continue reading. Figure 3 The first feed inlet 1b is located inside the receiving cavity 21. Material enters the receiving cavity 21 through the clearance opening 2d. The receiving cavity 21 collects the dispersed material. After initial collection, the material can enter the first extrusion channel 1a more orderly and smoothly through the first feed inlet 1b, and is discharged from the first discharge outlet 1c after being extruded into the inner matrix 211. In this way, the material processing time can be saved and the production efficiency can be improved.

[0088] In some embodiments, at least one of the circumferential surface of the first extrusion channel 1a and the outer circumferential surface of the inner mold 1 has a shaping structure for forming a protrusion 220 or a groove 230 in at least one of the inner substrate 211 and the outer jacket 212.

[0089] Specifically, the shaping structure located on the circumferential surface of the first extrusion channel 1a is used to form protrusions 220 or grooves 230 on the first circumferential surface 211a of the inner substrate 211, and the shaping structure located on the outer circumferential surface of the inner mold 1 is used to form protrusions 220 or grooves 230 on the second circumferential surface 212a of the outer jacket layer 212. In this way, by forming specific protrusions 220 or grooves 230 on the inner substrate 211 and the outer jacket layer 212 through the shaping structure, more functions can be achieved, enhancing the functionality of the product segment 210.

[0090] In some embodiments, please refer to Figure 4 and Figure 5 At least one of the first circumferential surface 211a and the second circumferential surface 212a is provided with a protrusion 220, which is used for a stop-fit. In this way, the protrusion 220 can increase the contact area between the first circumferential surface 211a and the second circumferential surface 212a, thereby enhancing the connection stability between the inner substrate 211 and the outer jacket 212 and improving the overall connection strength of the article segment 210.

[0091] In one embodiment, the first circumferential surface 211a is provided with a protrusion 220, which abuts against the second circumferential surface 212a. In another embodiment, the second circumferential surface 212a is provided with a protrusion 220, which abuts against the first circumferential surface 211a. In yet another embodiment, both the first circumferential surface 211a and the second circumferential surface 212a are provided with protrusions 220, with the protrusion 220 of the first circumferential surface 211a abutting against the second circumferential surface 212a, and the protrusion 220 of the second circumferential surface 212a abutting against the first circumferential surface 211a.

[0092] For example, please refer to Figure 4 and Figure 5Both the inner matrix 211 and the outer layer 212 have protrusions 220 formed through a shaping structure, wherein the protrusions 220 of the inner matrix 211 and the outer layer 212 are spaced apart circumferentially. This allows the protrusions 220 of the inner matrix 211 and the outer layer 212 to form multi-point support and fit, thereby significantly improving the overall connection strength of the product segment 250. Furthermore, the protrusions 220 can increase the volume of the inner matrix 211 and the outer layer 212, allowing the matrix segment 250 to generate a greater number of aerosol outlets when the product segment 210 is used as the matrix segment 250, thus improving the user experience.

[0093] For example, please refer to Figure 5 The first circumferential surface 211a of the inner substrate 211 forms a protrusion 220 through a shaping structure, and the second circumferential surface 212a of the outer layer 212 forms a groove 230 through a shaping structure. The protrusion 220 of the inner substrate 211 corresponds to the groove 230 of the outer layer 212. Thus, through the cooperation of the protrusion 220 and the groove 230, on the one hand, precise positioning of the inner substrate 211 and the outer layer 212 can be achieved during assembly, preventing relative rotation or misalignment. On the other hand, the protrusion 220 and the groove 230 can increase the contact area between the first circumferential surface 211a and the second circumferential surface 212a, thereby enhancing the connection stability of the inner substrate 211 and the outer layer 212 and improving the overall connection strength of the product segment 250. Furthermore, the protrusion 220 and the groove 230 also serve a positioning function, facilitating the loading and unloading of the inner substrate 211 and the outer layer 212.

[0094] In one embodiment, the shaping structure includes a shaping recess and a shaping protrusion. It should be understood that, for the shaping structure disposed on the outer peripheral surface of the inner mold 1, when the shaping structure is a shaping protrusion, the second circumferential surface 212a of the outer jacket layer 212 forms a groove 230; when the shaping structure is a shaping recess, the second circumferential surface 212a of the outer jacket layer 212 forms a protrusion 220. For the shaping structure disposed on the circumferential surface of the first extrusion channel 1a, when the shaping structure is a shaping protrusion, the first circumferential surface 211a of the inner substrate 211 forms a groove 230; when the shaping structure is a shaping recess, the first circumferential surface 211a of the inner substrate 211 forms a protrusion 220.

[0095] In one embodiment, multiple shaping recesses are provided on the circumferential surface of the first extrusion channel 1a, and these multiple shaping recesses are evenly spaced along the circumference. That is, after the shape of the inner substrate 211 is adjusted by the shaping recesses, the first circumferential surface 211a of the inner substrate 211 has multiple protrusions 220 evenly spaced along the circumference. In this way, the distance between any two adjacent protrusions 220 is equal. This facilitates precise fitting between the inner substrate 211 and the outer layer 212. On the other hand, the forces exerted between the inner substrate 211 and the outer layer 212 can be evenly distributed, which, in addition to enhancing the connection stability between the inner substrate 211 and the outer layer 212, can further prevent deformation or damage to the product segment 250.

[0096] In one embodiment, multiple shaping protrusions are provided on the circumferential surface of the first extrusion channel 1a, and these protrusions are evenly spaced along the circumference. That is, after the shape of the inner substrate 211 is adjusted by the shaping protrusions, the first circumferential surface 211a of the inner substrate 211 has multiple grooves 230 evenly spaced along the circumference. Thus, the distance between any two adjacent grooves 230 is equal. In this way, the multiple evenly distributed grooves 230 can serve as air channels for aerosol flow, allowing the aerosol to be evenly dispersed into each groove 230. This not only guides the aerosol to flow in a predetermined direction, reducing airflow turbulence and improving aerosol flow efficiency, but also prevents excessively high or low local aerosol concentrations, which could affect the user's suction experience.

[0097] It is understandable that the shaping structure set on the outer peripheral surface of the inner mold 1 has the same beneficial effect as the aforementioned, and will not be elaborated further here.

[0098] In another embodiment, when the shaping structure on the circumferential surface of the first extrusion channel 1a and the shaping structure on the outer circumferential surface of the inner mold 1 are of the same type, all shaping structures are distributed circumferentially at intervals. This is because, taking the shaping structure as a shaping recess as an example, both the first circumferential surface 211a of the inner substrate 211 and the second circumferential surface 212a of the outer jacket 212 have protrusions 220 formed, and the distribution positions of the protrusions 220 are approximately the same. The contact between the two layers of protrusions 220 will result in a larger gap between the inner substrate 211 and the outer jacket 212, causing the inner substrate 211 and the outer jacket 212 to be unable to be tightly connected.

[0099] In some embodiments, the first extrusion channel 1a has a shaping structure on a second side along a first direction.

[0100] The second side of the first direction is the discharge side along the first direction.

[0101] For example, the shaping structure is located at the first discharge port 1c. This not only facilitates the setting of the shaping structure and reduces the difficulty of design and manufacturing, but also allows direct observation of the shaping structure's adjustment process of the inner matrix 211's shape as the inner matrix 211 is extruded from the first discharge port 1c, ensuring the accuracy of the inner matrix 211's size and shape.

[0102] In some embodiments, the inner mold 1 has a shaping structure on the second side along the first direction.

[0103] For example, the shaping structure is located at the second discharge port 2c. This not only facilitates the setting of the shaping structure and reduces the difficulty of design and manufacturing, but also allows direct observation of the shaping structure's adjustment process of the outer jacket layer 212's shape as it is extruded from the second discharge port 2c, ensuring the accuracy of the outer jacket layer 212's size and shape.

[0104] In some embodiments, please refer to Figure 3 , Figure 6 and Figure 7 The inner mold 1 has a first limiting platform 11, and the circumferential surface of the receiving cavity 21 has a second limiting platform 22. The first limiting platform 11 and the second limiting platform 22 abut against each other to restrict the inner mold 1 from moving toward the second side of the first direction.

[0105] Specifically, when the end face of the inner mold 1 facing the second side is flush with the end face of the outer mold 2 facing the second side, the first limiting platform 11 and the second limiting platform 22 abut against each other. In this way, on the one hand, the cooperation of the first limiting platform 11 and the second limiting platform 22 effectively prevents the preparation mold 10 from shifting or displacing during operation, thereby improving the processing accuracy and product quality of the inner substrate 211 and the outer layer 212. On the other hand, during the assembly process of the inner mold 1 and the outer mold 2, the operator can determine whether the preparation mold 10 has been assembled by checking whether the first limiting platform 11 and the second limiting platform 22 abut against each other, or whether the end face of the inner mold 1 facing the second side is flush with the end face of the outer mold 2 facing the second side. This improves assembly efficiency and thus increases production efficiency.

[0106] In one embodiment, please refer to Figure 6 and Figure 7 The first limiting platform 11 and the second limiting platform 22 are roughly in a ring shape, which increases the contact area between the first limiting platform 11 and the second limiting platform 22 and improves the limiting effect.

[0107] In one embodiment, there are multiple first limiting platforms 11 and multiple second limiting platforms 22. The multiple first limiting platforms 11 are distributed at intervals along the circumference, and the multiple second limiting platforms 22 are distributed at intervals along the circumference. Each first limiting platform 11 has a corresponding second limiting platform 22.

[0108] In some embodiments, please refer to Figure 3 , Figure 7 and Figure 8 The inner mold 1 includes an annular sleeve 12 and a stop 13. The annular sleeve 12 forms a first extrusion channel 1a, and the stop 13 is disposed within the first extrusion channel 1a. The stop 13 is used to block the flow of material, and the material cannot enter the first extrusion channel 1a through the stop 13.

[0109] For example, please refer to Figure 3 and Figure 8 The stop 13 is located at the first feed inlet 1b.

[0110] For example, please continue reading Figure 3 The outer periphery of the annular sleeve 12 abuts against the cavity wall of the receiving cavity 21, which enhances the connection stability between the annular sleeve 12 and the outer mold 2. An extrusion gap 1a1 is defined between the circumferential surface of the stop member 13 and the circumferential surface of the first extrusion channel 1a, and the extrusion gap 1a1 communicates with the first feed port 1b. The extrusion gap 1a1 is the channel through which the material passes during the extrusion process. That is, the material first enters the receiving cavity 21 through the clearance port 2d, then enters the first extrusion channel 1a through the first feed port 1b and the extrusion gap 1a1, is extruded into the inner matrix 211 within the first extrusion channel 1a, and is discharged from the first discharge port 1c.

[0111] Furthermore, taking the plane perpendicular to the first direction as the projection plane, the projected area of ​​the extrusion gap 1a1 is smaller than the projected area of ​​the first extrusion channel 1a. In this way, the material is initially compressed when passing through the extrusion gap 1a1. The narrow extrusion gap 1a1 can squeeze out trapped gases such as air in the material, so that the material is tightly bound together, thereby increasing the density of the extrudate and making the inner matrix 211 less prone to disintegration, thus improving product quality.

[0112] In some embodiments, please refer to Figure 7 and Figure 8 The die 10 includes multiple connecting parts 3, which are evenly spaced circumferentially in the first extrusion channel 1a. The connecting parts 3 connect the annular sleeve 12 and the stop member 13. In this way, the connecting parts 3 can enhance the connection stability between the stop member 13 and the annular sleeve 12, and prevent the stop member 13 from loosening or shifting during operation.

[0113] In some embodiments, the outer mold 2 is a one-piece molded structure. This not only reduces manufacturing difficulty, improves production efficiency, and reduces production costs, but also avoids the gaps created by splicing multiple parts, preventing material from getting stuck in the gaps and affecting the cleanliness and service life of the outer mold 2.

[0114] In some embodiments, the inner mold 1 is a one-piece molded structure. This not only reduces manufacturing difficulty, improves production efficiency, and reduces production costs, but also avoids gaps that can occur when multiple parts are spliced ​​together, preventing material from getting stuck in the gaps and affecting the cleanliness and service life of the inner mold 1.

[0115] In one embodiment, please refer to Figure 6 At least a portion of the outer periphery of the bottom side of the outer mold 2 is horizontal, so that the outer mold 2 can be placed stably on a flat surface, ensuring that the outer mold 2 will not be disturbed during operation, thus reducing the impact on product quality.

[0116] Please see Figure 9 This application also provides a preparation apparatus 100, including two extruders 20 and a preparation mold 10 in any embodiment of this application. One of the two extruders 20 is connected to a first extrusion channel 1a, and the other of the two extruders 20 is connected to a second extrusion channel 2a.

[0117] The preparation apparatus 100 can be used to prepare aerosol-generating products 200.

[0118] For example, please continue reading Figure 9 One extruder 20 is connected to the first extrusion channel 1a via the first feed port 1b, and the other extruder 20 is connected to the second extrusion channel 2a via the second feed port 2b. That is, the two extruders 20 are located on different sides of the preparation mold 10. In this way, on the one hand, the two extruders 20 can simultaneously feed material to the preparation mold 10, significantly improving production efficiency and increasing the yield of aerosol-generated products 200. On the other hand, it avoids interference between the two extruders 20, improving operational safety.

[0119] Please see Figure 10 The aerosol generating article 200 provided in this application embodiment includes at least one functional segment 240, a matrix segment 250, and the functional segment 240 is disposed along a first direction.

[0120] In one embodiment, at least one functional segment 240 uses a workpiece segment 210. Taking three functional segments 240 as an example, one functional segment 240 may use a workpiece segment 210, while the other two functional segments 240 may not use a workpiece segment 210. Alternatively, two functional segments 240 may use a workpiece segment 210, while the remaining functional segment 240 may not use a workpiece segment 210. Furthermore, all three functional segments 240 may use a workpiece segment 210.

[0121] This application does not specifically limit the material of functional segment 240. In one embodiment, functional segment 240 includes a skeleton component and an adhesive component. The skeleton component provides a skeleton for functional segment 240 to facilitate molding, and the adhesive is used to wet and closely contact the interfaces of the various components in functional segment 240, thereby bonding the powders, liquids, etc. of the various components. Exemplarily, the skeleton component includes one or more of calcium carbonate, talc, kaolin, diatomaceous earth, cellulose, hemicellulose and lignin, tobacco raw materials, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants; the adhesive component includes one or more of xanthan gum, sodium alginate, pullulan, tamarind polysaccharide, guar gum, and modified cellulose, wherein the modified cellulose is selected from one or more of sodium carboxymethyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose.

[0122] For example, please refer to Figure 10 Functional segment 240 includes support segment 241. In one embodiment, support segment 241 is a workpiece segment 210.

[0123] For example, please refer to Figure 10 Functional section 240 includes a cooling section 242, which is used to reduce the temperature of the aerosol. This makes the aerosol suitable for user inhalation. In one embodiment, the cooling section 242 is a product section 210.

[0124] For example, please refer to Figure 10 Functional segment 240 includes a filter segment 243 for filtering aerosols. Exemplarily, filter segment 243 can block substances of a target particle size and can also adjust the suction resistance. For example, filter segment 243 can filter large-diameter particles, similar to powdery substances. Aerosols filtered by filter segment 243 have a higher particle size uniformity and a smoother taste. In one embodiment, filter segment 243 is a product segment 210.

[0125] The cooling section 242 and the filter section 243 can be made of the same material or different materials.

[0126] For example, please refer to Figure 10 Functional segment 240 includes a pre-plug segment 244, which seals the distal lip of matrix segment 250 to prevent aerosol backflow, allowing the user to smoothly aspirate the aerosol. In one embodiment, pre-plug segment 244 is an article segment 210.

[0127] In one embodiment, please refer to Figure 10 The fore plug section 244, the matrix section 250, the support section 241, the cooling section 242, and the filter section 243 are connected sequentially along the first direction.

[0128] In one embodiment, the aerosol generating article 200 includes a coating layer that covers the outer periphery of the matrix section 250 and the outer periphery of the functional section 240. Exemplarily, the coating layer covers the outer peripheral surfaces of the matrix section 250 and the functional section 240. That is, the outer peripheries of the front plug section 244, the matrix section 250, the support section 241, the cooling section 242, and the filter section 243 are all covered by the coating layer. The coating layer can be a single layer, or two or more layers can be designed according to the design requirements and manufacturing process of the aerosol generating article 200. For example, during manufacturing, the support section 241, the cooling section 242, and the filter section 243 can be first wrapped with a single coating layer, and then another coating layer can be used to wrap the matrix section 250 and the front plug section 244. Other combinations are also possible.

[0129] For example, the encapsulation layer is formed with side holes for introducing external gases, such as air, into the interior of the aerosol generating article 200 to maintain the air pressure balance inside the aerosol generating article 200.

[0130] In one embodiment, the matrix segment 250 includes plant materials, auxiliary materials, smoke-generating agent materials, adhesive materials, and fragrance materials. That is, the inner matrix 211 and the outer layer 212 may include plant materials, auxiliary materials, smoke-generating agent materials, adhesive materials, and fragrance materials.

[0131] Plant-based ingredients are used to generate aerosols upon heating. Additive ingredients provide skeletal support for the plant-based ingredients. Smoke-generating ingredients produce a large amount of smoke upon heating. Binder ingredients bind the component ingredients together. Fragrance ingredients provide characteristic aromas. Thus, the plant-based and smoke-generating ingredients ensure sufficient aerosol generation, while the fragrance ingredients enhance aroma release during inhalation, improving the user experience. Additive ingredients not only improve the flowability of the mixture but also create a porous structure in matrix segment 250, facilitating aerosol extraction and flow. Binder ingredients ensure a stable mixture of plant-based powder and additives, preventing a loose structure.

[0132] In one embodiment, the plant-based raw materials are one or more combinations of tobacco leaves, tobacco fragments, tobacco stems, tobacco dust, and aromatic plants, which are powdered after being crushed. The plant-based raw materials are the core source of the aroma, and the endogenous substances in them can provide users with physiological satisfaction. Endogenous substances, such as alkaloids, enter the bloodstream and promote the pituitary gland to produce dopamine, thereby achieving physiological satisfaction.

[0133] In one embodiment, the auxiliary raw material can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. The inorganic fillers include one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic fillers can provide skeletal support for the plant material, and also have micropores, which can increase the porosity of the matrix section 250, thereby increasing the aerosol release rate.

[0134] Lubricants include one or more of the following: candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can increase the flowability of plant-based powders, reduce friction between powder particles, resulting in a more uniform overall density of the powder. They can also reduce the pressure required during extrusion molding and decrease die wear.

[0135] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can, to some extent, slow down the loss of aroma compounds during storage, increase their stability, and improve the sensory quality of the product.

[0136] In one embodiment, the smoke-generating agent raw material may include one or more combinations of: monohydric alcohol (such as menthol); polyhydric alcohol (such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol, and tetraethylene glycol); esters of polyhydric alcohols (such as triacetin, triethyl citrate, a mixture of diacetin, triethyl citrate, methyl benzoate, and triglyceride); monocarboxylic acid; dicarboxylic acid; polycarboxylic acid (such as lauric acid and myristic acid) or aliphatic esters of polycarboxylic acids (such as dimethyl dodecanoate, dimethyl tetradecanoate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl lauryl carbonate, triacetin, mesoerythritol, a mixture of diacetin, diethyl octanoate, triethyl citrate, methyl benzoate, phenylacetic acid, ethyl vanillate, triglyceride, and lauryl acetate).

[0137] In one embodiment, the adhesive raw material achieves close contact with the component raw material through interfacial wetting, generating intermolecular attraction and thus serving to bind the component raw materials, such as powders and liquids. The adhesive raw material can be one or more combinations of natural plant extracts and non-ionic modified viscous polysaccharides, including tamarind polysaccharide, guar gum, and modified cellulose (such as carboxymethyl cellulose). The adhesive is used to bond particles together, preventing them from easily falling apart, and also improves the water resistance of the matrix segment 250, and is harmless to the human body.

[0138] In one embodiment, the flavoring ingredient is used to provide characteristic aromas, such as hay, roasted sweetness, or solid or liquid substances of nicotine. The flavoring ingredient may include one or more combinations of tobacco, aromatic plant extracts, extracts, essential oils, and absolutes; the flavoring ingredient may also include monomeric aroma substances, such as one or more combinations of megastigmatrienone, neophytadiene, geraniol, nerol, etc.
