In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0046] The present application embodiment provides a mold for manufacturing an aerosol generating product, see Figures 1 to 14 The mold 100 includes a first body 10, a second body 20 and a third body 30 sequentially arranged along a first direction.

[0047] The mold provided in the embodiment of the present application can prepare the aerosol generating product 200 by a continuous extrusion process, and the extrusion process can be carried out by using the mold 100 provided in the embodiment of the present application in combination with any suitable extruder. For example, the extruder can be a hydraulic ram extruder, a twin-screw extruder, a single-screw extruder, etc.

[0048] The mixture is extruded from the extrusion die 100 into a honeycomb, which is then dried to form all or part of the final honeycomb-shaped aerosol-generating article 200 .

[0049] See also Figures 1 to 6The third body 30 is formed with an extrusion channel 30a extending along the first direction. The end of the extrusion channel 30a away from the second body 20 forms a discharge port 30d, that is, the raw material mixture can be extruded through the extrusion channel 30a to form various cross-section products or semi-finished products.

[0050] See also Figures 7 to 11 The second body 20 is provided with a first column 21 and a feed channel 20a. Please continue to refer to Figures 4 to 6 The feed channel 20a extends along the first direction and is connected to the extrusion channel 30a, and the first column 21 extends along the first direction to the extrusion channel 30a, that is, the raw material mixture can enter the extrusion channel 30a through the feed channel 20a, and be extruded through the discharge port 30d to form products or semi-finished products with various cross-sections.

[0051] See also Figures 4 to 6 , Fig.10 as well as Fig.11 The first body 10 is provided with a first cavity 10a, which runs through the opposite ends of the first body 10 along the first direction and is connected to the feed channel 20a. The end of the first cavity 10a away from the second body 20 is a feed port 10b, that is, the raw material mixture can be guided from one end of the first body 10 to the other end through the first cavity 10a.

[0052] The first body 10 is provided with a second column 11 , and the second column 11 extends along the first direction to the extrusion channel 30 a .

[0053] Exemplarily, a center line of the extrusion channel 30a along the extension direction coincides with a center axis C of the die 100 along the first direction.

[0054] See also Figure 4 , the central axis C of the mold 100 along the first direction is a virtual reference line.

[0055] The coincidence mentioned here means that the center line of the extrusion channel 30a along the extension direction roughly coincides with or completely coincides with the central axis C of the mold 100 along the first direction. That is to say, there can be a certain deviation between the center line of the extrusion channel 30a along the extension direction and the central axis C of the mold 100 along the first direction, and the central axis C of the mold 100 along the first direction roughly passes through the center line of the extrusion channel 30a.

[0056] Exemplarily, a center line of the second column 11 along the extension direction coincides with a center axis C of the mold 100 along the first direction.

[0057] The coincidence mentioned here means that the center line of the second column 11 along the extension direction roughly coincides with or completely coincides with the central axis C of the mold 100 along the first direction. That is to say, there can be a certain deviation between the center line of the second column 11 along the extension direction and the central axis C of the mold 100 along the first direction, and the central axis C of the mold 100 along the first direction roughly passes through the center line of the second column 11.

[0058] The second column 11 is closer to the central axis C of the mold 100 than the first column 21. Exemplarily, the first column 21 is arranged around the circumference of the second column 11, that is, the first column 21 is arranged around the circumference of the second column 11, and the first column 21 is arranged at intervals along the circumference of the second column 11.

[0059] See also Figures 4 to 6 The second column 11 and the first column 21 both extend along the first direction to the extrusion channel 30a, the first column 21 is arranged around the second column 11, the second column 11, the first column 21 and the inner wall of the extrusion channel 30a are arranged at intervals, and can be used to extrude and form the wall thickness or middle rib position characteristics of the aerosol generating product 200, the second column 11 can be used to extrude and form the central hole 200a of the aerosol generating product 200, the first column 21 can be used to extrude and form the airway hole 200b located on the peripheral side of the central hole 200a, the extrusion channel 30a can be used to extrude and define the peripheral shape of the aerosol generating product 200, the raw material mixture is extruded through the extrusion channel 30a, and the extruded extrudate forms a honeycomb-shaped product or semi-finished product (please refer to Figure 12 to Figure 14 ).

[0060] That is to say, the shape of the second column 11 can determine the shape of the center hole 200a, the shape of the first column 21 can determine the shape of the airway hole 200b located on the periphery of the center hole 200a, and the shape of the extrusion channel 30a can determine the shape of the aerosol generating product 200. Thus, by matching different first bodies 10, second bodies 20 and third bodies 30, aerosol generating products 200 with different cross-sectional shapes can be obtained.

[0061] Exemplarily, the aerosol-generating product 200 is a particle combination, for example, a reconstituted tobacco medium containing smoke-generating agents, tobacco and other ingredients, and is an integrated structure formed by a continuous extrusion process. Extrusion molding refers to a processing method in which a raw material mixture is added to an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through the mold 100 including the embodiment of the present application to form various cross-sectional products or semi-finished products. In addition, the products or semi-finished products extruded through the mold 100 can be used to make different components of the aerosol-generating product 200, such as a cooling section, a smoke-generating section, a support section, a filtering section, etc., or can be directly used to make the entire aerosol-generating product 200, which is not limited here.

[0062] When the aerosol generating product 200 is heated and atomized, the aerosol generating product 200 releases aerosol when heated, and the aerosol flows out through the gaps or micropores of the partition walls between each airway hole 200b and the central hole 200a and is collected in the airway hole 200b and the central hole 200a, and is transported to the suction end under the action of the suction negative pressure.

[0063] It should be noted that the materials of the first body 10, the second body 20 and the third body 30 may be consistent or inconsistent. Since the mold 100 is used to manufacture the aerosol generating product 200, the extrusion pressure during the extrusion process is relatively high, and the mold 100 needs to have a relatively high strength. In addition, the raw material mixture of the aerosol generating product 200 contains water, and the mold 100 needs to have a certain ability to resist corrosion, etc. Therefore, the materials of the first body 10, the second body 20 and the third body 30 can all be high-strength stainless steel, such as austenitic stainless steel, martensitic stainless steel, etc.

[0064] In the embodiment of the present application, the first direction refers to the feeding direction. For example, when the appearance profile of the mold 100 is cylindrical, the first direction is the height direction perpendicular to the bottom surface of the mold 100, or the first direction is the axial direction of the mold 100. For another example, when the appearance profile of the mold 100 is a rectangular parallelepiped, the first direction is still the direction defined above, that is, the feeding direction, and the first direction can be any direction of the length, width, and height of the rectangular parallelepiped.

[0065] In other embodiments, when the appearance of the mold 100 is cylindrical, the first direction may be inclined relative to the height direction of the bottom surface of the mold 100, or the first direction may be inclined relative to the axial direction of the mold 100. When the appearance of the mold 100 is a rectangular parallelepiped, the first direction may be inclined relative to any one of the length, width, and height of the rectangular parallelepiped.

[0066] In some other embodiments, the first direction refers to a feeding direction, and the first direction may be in a folded line shape, for example, the mold 100 feeds from the side and extrude from the top or bottom; or, the mold 100 feeds from the top and extrude from the side.

[0067] The mold for manufacturing aerosol-generating products provided in the embodiment of the present application, the mold 100 includes a first body 10, a second body 20 and a third body 30 arranged in sequence along a first direction, that is, by arranging the first body 10, the second body 20 and the third body 30, the convenience of processing the mold 100 is improved. The first body 10 is provided with a first cavity 10a, the second body 20 is provided with a feed channel 20a, and the third body 30 is formed with an extrusion channel 30a extending along the first direction. The end of the first cavity 10a away from the second body 20 forms a feed port 10b, and the end of the extrusion channel 30a away from the second body 20 forms a discharge port 30d, that is, the raw material mixture can enter the first cavity 10a, the feed channel 20a, and the extrusion channel 30a in sequence through the feed port 10b, and be extruded through the discharge port 30d to form products or semi-finished products with various cross-sections. Since the first body 10 is provided with the second column 11, the second body 20 is provided with the first column 21, the second column 11 and the first column 21 both extend along the first direction to the extrusion channel 30a, and the first column 21 is arranged around the circumference of the second column 11, so that the aerosol generating product 200 with different cross-sectional shapes or sizes can be obtained by controlling the shapes and gaps of the second column 11, the first column 21, and the extrusion channel 30a, that is, the aerosol generating product 200 with different cross-sectional shapes or sizes can be obtained by replacing one or two of the first body 10, the second body 20, or the third body 30, without replacing the entire mold 100, thereby reducing production costs. In addition, the porosity of the mold 100 can be controlled by controlling the sizes of the first cavity 10a, the feed channel 20a, and the extrusion channel 30a, which is conducive to ensuring that the pressure rise is formed during the extrusion process, promoting the molding of the aerosol generating product 200, and improving the compactness of the aerosol generating product 200.

[0068] In the related art, considering the strength of the mold, the porosity variation range of the feed end is limited, and it is impossible to ensure that the porosity of the feed end is always greater than the porosity of the discharge end. That is, the porosity of some areas of the feed end is smaller than the porosity of the discharge end, thereby affecting the extrusion effect and stability of the aerosol generating product.

[0069] The mold provided in the embodiment of the present application includes a first body 10, a second body 20 and a third body 30 arranged in sequence along a first direction. For an aerosol generating product 200 with a smaller porosity, the porosity of the extrusion channel 30a can be made smaller than the porosity of the feed channel 20a by modifying the characteristic dimensions of the mold 100 (for example, the dimensions of the first cavity 10a, the feed channel 20a, the extrusion channel 30a, or the dimensions or gaps of the second column 11 and the first column 21, etc.), thereby improving the extrusion effect and stability of the aerosol generating product 200 and reducing the impact on the strength of the mold 100.

[0070] On a plane perpendicular to the first direction, the flow cross-sectional area of ​​the feed channel 20a located upstream in the feed direction is not less than the flow cross-sectional area of ​​the feed channel 20a located downstream in the feed direction. In this way, the raw material mixture can maintain a certain extrusion pressure in the feed channel 20a, or the extrusion pressure gradually increases, which is beneficial to the feeding of the raw material mixture.

[0071] It should be noted that the flow section refers to the cross section orthogonal to all streamlines of the elementary flow or the total flow, that is, the plane perpendicular to the flow velocity cluster, such as the air flow or liquid flow. When the streamline clusters are not parallel to each other, the flow section is a curved surface; when the streamline clusters are parallel straight lines, the flow section is a plane.

[0072] In the plane perpendicular to the first direction, there are many situations in which the flow cross-sectional area of ​​the feed channel 20a located upstream in the feeding direction is not less than the flow cross-sectional area of ​​the feed channel 20a located downstream in the feeding direction. For example, in one embodiment, the flow cross-sectional area of ​​the feed channel 20a is the same along the feeding direction, that is, each feed channel 20a is of equal diameter. In this way, the raw material mixture can maintain a certain extrusion pressure in the feed channel 20a, which is conducive to the feeding of the raw material mixture.

[0073] In other embodiments, the flow cross-sectional area of ​​each feed channel 20a gradually decreases along the feed direction, that is, each feed channel 20a is variable in diameter, and the flow cross-sectional area of ​​the feed channel 20a located upstream in the feed direction is larger than the flow cross-sectional area of ​​the feed channel 20a located downstream in the feed direction. In this way, the extrusion pressure on the raw material mixture in the feed channel 20a can be gradually increased, which is conducive to the preliminary kneading of the raw material mixture.

[0074] In some other embodiments, the flow cross-sectional areas of some feed channels 20a may be the same in size, and the flow cross-sectional areas of some feed channels 20a may gradually decrease along the feeding direction.

[0075] On a plane perpendicular to the first direction, the flow cross-sectional area of ​​the extrusion channel 30a located upstream in the extrusion direction is not less than the flow cross-sectional area of ​​the extrusion channel 30a located downstream in the extrusion direction. In this way, the raw material mixture can maintain a certain extrusion pressure in the extrusion channel 30a, or the extrusion pressure gradually increases, so that the raw material is gradually kneaded and formed.

[0076] In the plane perpendicular to the first direction, there are many situations in which the flow cross-sectional area of ​​the extrusion channel 30a located upstream in the extrusion direction is not less than the flow cross-sectional area of ​​the extrusion channel 30a located downstream in the extrusion direction. For example, in one embodiment, the flow cross-sectional area of ​​the extrusion channel 30a is the same along the extrusion direction, that is, each extrusion channel 30a is of equal diameter. In this way, the raw material mixture can maintain a certain extrusion pressure in the extrusion channel 30a, which is conducive to the complete kneading of the grid structure.

[0077] In other embodiments, the flow cross-sectional area of ​​each extrusion channel 30a gradually decreases along the extrusion direction, that is, each extrusion channel 30a is variable in diameter, and the flow cross-sectional area of ​​the extrusion channel 30a located upstream in the extrusion direction is larger than the flow cross-sectional area of ​​the extrusion channel 30a located downstream in the extrusion direction. In this way, the raw material mixture can be further extruded in the extrusion channel 30a, which is conducive to the complete kneading of the grid structure.

[0078] In some other embodiments, the flow cross-sectional areas of some extrusion channels 30a may be the same in size, and the flow cross-sectional areas of some extrusion channels 30a may gradually decrease along the extrusion direction.

[0079] For example, on a plane perpendicular to the first direction, the maximum value of the flow cross-sectional area of ​​the extrusion channel 30a is less than or equal to the minimum value of the flow cross-sectional area of ​​the feed channel 20a, so that the raw material mixture can maintain a certain extrusion pressure in the extrusion channel 30a, or the extrusion pressure gradually increases. When the maximum value of the flow cross-sectional area of ​​the extrusion channel 30a is less than the minimum value of the flow cross-sectional area of ​​the feed channel 20a, after the raw material mixture enters the extrusion channel 30a through the feed channel 20a, it is used to make the raw material mixture further extruded in the extrusion channel 30a, which is conducive to promoting the complete kneading of the grid structure and controlling the density of the aerosol generating article 200 when the porosity of the aerosol generating article 200 is constant.

[0080] For example, see Figures 4 to 9The second body 20 includes a first connecting section 22 and a second connecting section 23 arranged in sequence along the first direction. The first connecting section 22 is arranged close to the first body 10 and forms a second cavity 20b. The second connecting section 23 is provided with a feeding channel 20a and a first column 21. The feeding channel 20a is connected with the first cavity 10a through the second cavity 20b. In this way, the raw material mixture can first enter the second cavity 20b from the first cavity 10a, and then enter the feeding channel 20a through the second cavity 20b. When the size of the first column 21 along the first direction is constant, the length of the feeding channel 20a is shortened, thereby reducing the resistance encountered by the raw material mixture during the feeding process, which is conducive to the feeding of the raw material mixture.

[0081] Of course, the second body 20 may not be provided with the first connecting section 22, that is, the second cavity 20b is not provided, that is, the raw material mixture first directly enters the feeding channel 20a from the first cavity 10a.

[0082] There are multiple feed channels 20a. By providing multiple feed channels 20a, while ensuring the uniformity of feed, the raw material mixture can also be subjected to a certain extrusion force in the extrusion channel 30a.

[0083] It should be noted that the number of the first columns 21 is not limited here. For example, the number of the first columns 21 may be one, or the number of the first columns 21 may be more than one.

[0084] It should be noted that, in the embodiments of the present application, “plurality” refers to a number including two or more than two.

[0085] For example, see Figure 3 , Figure 6 , Fig. 9 as well as Fig.14 , each feed channel 20a passes through the opposite ends of the second connecting section 23 along the first direction, and the first column 21 is arranged on the side of the second connecting section 23 away from the second cavity 20b. That is, the raw material mixture can be guided from one end of the second connecting section 23 to the other end through the feed channel 20a, the first column 21 is arranged on the side of the second connecting section 23 away from the second cavity 20b, and the first column 21 extends to the extrusion channel 30a, that is, the raw material mixture can enter the extrusion channel 30a through the feed channel 20a, fill in the gaps between the first columns 21 or between the first columns 21 and the inner wall of the extrusion channel 30a, and be extruded through the discharge port 30d to form products or semi-finished products with various cross sections.

[0086] For example, see Figure 6 as well as Fig. 9A through hole 20c is formed inside the second connecting section 23, and the second column 11 extends to the extrusion channel 30a through the hole 20c, and each first column 21 is arranged around the circumference of the second column 11. By providing the through hole 20c, it is convenient for the second column 11 to extend to the extrusion channel 30a through the hole 20c, and each first column 21 is arranged around the circumference of the through hole 20c. For example, each first column 21 is arranged along the circumferential direction around the center of the second column 11, so that each first column 21 is arranged around the circumference of the second column 11.

[0087] For example, see Figures 4 to 8 A partial area of ​​the inner wall of the second connecting section 23 extends radially to form a second connecting rib 24 , and one end of the second connecting rib 24 away from the inner wall of the second connecting section 23 is connected to the first column 21 .

[0088] That is, by providing the second connecting rib 24 for connecting the first pillar 21 , and the second connecting rib 24 extending along the radial direction of the second connecting section 23 , the first pillar 21 is conveniently extended along the first direction.

[0089] It should be noted that the number of the second connecting ribs 24 is not limited herein. For example, the number of the second connecting ribs 24 may be one, or the number of the second connecting ribs 24 may be multiple.

[0090] For example, please refer to Figures 4 to 8 There are multiple first columns 21 and multiple second connecting ribs 24, and the first columns 21 and the second connecting ribs 24 correspond to each other one by one. Multiple first columns 21 are arranged at intervals and surround to form a through hole 20c. The second column 11 extends to the extrusion channel 30a through the hole 20c, and each first column 21 is arranged around the second column 11.

[0091] See also Figures 4 to 8 The inner wall of the second connecting section 23 , the second connecting rib 24 and the gap between the first column 21 form a feeding channel 20a, and the raw material mixture can enter the extrusion channel 30a through the inner wall of the second connecting section 23 , the second connecting rib 24 and the gap between the first column 21 .

[0092] For example, see Figures 4 to 6The third body 30 includes a third connecting section 31 and a fourth connecting section 32 arranged in sequence along the first direction. The third connecting section 31 is arranged close to the second body 20 and is formed with a third cavity 30b. The fourth connecting section 32 is provided with an extrusion channel 30a. The feed channel 20a and the extrusion channel 30a are connected through the third cavity 30b. In this way, the raw material mixture can first enter the third cavity 30b from the feed channel 20a, and then enter the extrusion channel 30a through the third cavity 30b. The setting of the third cavity 30b allows the raw material mixture entering the third body 30 from the feed channel 20a to be temporarily stored in the third cavity 30b. When the third cavity 30b is filled, a certain extrusion pressure is formed and extruded from the discharge port 30d. The setting of the third cavity 30b is conducive to the raw material mixture entering the extrusion channel 30a from the feed channel 20a.

[0093] Generally, after the cross-sectional shape of the aerosol generating product 200 is determined, that is, the porosity of the discharge port 30d of the mold 100 is determined, the size of the third cavity 30b can be changed so that the porosity of the third cavity 30b is greater than the porosity of the discharge port 30d, thereby ensuring that the aerosol generating product 200 is compact.

[0094] Similarly, the porosity of the second cavity 20b and the first cavity 10a can be changed by changing the size of the second cavity 20b and the first cavity 10a. That is, the porosity of the second cavity 20b and the first cavity 10a can be controlled by changing the size of the second cavity 20b and the first cavity 10a, thereby improving the reliability and accuracy of the mold 100.

[0095] Of course, the third main body 30 may not be provided with the third connecting section 31, that is, the third cavity 30b is not provided, that is, the raw material mixture directly enters the extrusion channel 30a from the feeding channel 20a.

[0096] Exemplarily, when projected on a plane perpendicular to the first direction, the projection of the feed channel 20a is within the projection range of the third cavity 30b, that is, the feed channel 20a will not be blocked by the third body 30. In other words, the provision of the third cavity 30b can, to a certain extent, prevent the third body 30 from blocking the feed channel 20a, that is, by providing the third cavity 30b, the raw material mixture can smoothly enter the third cavity 30b of the third body 30 from the feed channel 20a, and then enter the extrusion channel 30a from the third cavity 30b, which is beneficial to the extrusion of the raw material mixture.

[0097] For example, see Figures 4 to 6, a guide surface 30c is formed on the inner side wall of the extrusion channel 30a on the side close to the third cavity 30b, and the distance between the guide surface 30c and the center of the third body 30 gradually decreases along the direction from the third cavity 30b to the extrusion channel 30a. In other words, along the extrusion direction, the distance between the guide surface 30c and the center of the third body 30 gradually decreases. That is, by forming the guide surface 30c at the connection between the third cavity 30b and the extrusion channel 30a, it is beneficial for the raw material mixture in the third cavity 30b to be guided to the extrusion channel 30a through the guide surface 30c, which is beneficial for the extrusion of the raw material mixture.

[0098] For example, see Figures 4 to 6 , Fig.10 as well as Fig.11 A partial area of ​​the inner wall of the first cavity 10 a extends radially to form a first connecting rib 12 , and the first connecting rib 12 is connected to the second column 11 .

[0099] That is, by providing the first connecting rib 12 for connecting the second column 11 , and the first connecting rib 12 extending along the radial direction of the first connecting section 22 , the second column 11 is conveniently extended along the first direction.

[0100] Specifically, the first connecting rib 12 extends radially along the first connecting section 22 , passes through the center line of the first cavity 10 a and then extends to the inner wall on the opposite side of the first cavity 10 a . The second column 11 is disposed at the center line of the first connecting rib 12 .

[0101] It should be noted that the size of the first connecting rib 12 along the first direction of the first body 10 is not limited here. Exemplarily, the first connecting rib 12 extends from one end of the first direction of the first body 10 to the other end of the first direction of the first body 10, which can ensure the strength of the first connecting rib 12.

[0102] For example, see Figures 1 to 3 , the end of the extrusion channel 30a away from the second body 20 forms a discharge port 30d, and the second column 11 and the first column 21 both extend to the discharge port 30d. By setting the second column 11 and the first column 21 to both extend to the discharge port 30d, that is, the second column 11 and the first column 21 are both extended to the end of the extrusion channel 30a away from the second body 20, that is, the ends of the second column 11 and the first column 21 can be flush with the discharge port 30d or exceed the discharge port 30d, so that it is convenient to extrude the raw material mixture to form various cross-section products or semi-finished products.

[0103] Of course, in other embodiments, the second column 11 and / or the first column 21 may not extend to the discharge port 30d, that is, the end of the second column 11 and / or the first column 21 is located between the discharge port 30d and the feed channel 20a, as long as the raw material mixture can be extruded to form various cross-sectional products or semi-finished products.

[0104] It should be noted that the shape of the extrusion channel 30a is not limited here. For example, on a plane perpendicular to the first direction, the cross-sectional shape of the extrusion channel 30a is circular (see Figures 1 to 3 ), elliptical, track-shaped or polygonal.

[0105] The extrusion channel 30a may be used to extrude and define the outer peripheral shape of the aerosol-generating article 200, that is, the cross-sectional shape of the aerosol-generating article 200 is circular, elliptical, racetrack-shaped or polygonal.

[0106] The cross-sectional shape of the extrusion channel 30 a refers to the cross-sectional shape of the extrusion channel 30 a cut along a plane perpendicular to the first direction.

[0107] Among them, the runway shape refers to: a shape similar to an athletics track, composed of two semicircles and two parallel straight edges alternately connected.

[0108] It should be noted that the shape of the first column 21 is not limited here. For example, on a plane perpendicular to the first direction, the cross-sectional shape of the first column 21 is circular or elliptical (see Figure 1 ), track-shaped, polygonal (see Figure 3 ) or fan-shaped (see Figure 2 ).

[0109] The cross-sectional shape of the first pillar 21 refers to the cross-sectional shape of the first pillar 21 cut along a plane perpendicular to the first direction.

[0110] The first column 21 can be used to extrude the airway hole 200b located around the central hole 200a. That is, the cross-sectional shape of the airway hole 200b extruded by the first column 21 is circular, elliptical, racetrack-shaped, polygonal or fan-shaped.

[0111] Exemplarily, the number of airway holes 200b is multiple, and the shape and size of each airway hole 200b are the same. For example, all airway holes 200b are equilateral triangles, and the side lengths of all equilateral triangles are equal. For another example, all airway holes 200b are circular with the same radius. In this way, each airway hole 200b of the aerosol generating product 200 can be formed based on the same molding mold 100, reducing manufacturing costs.

[0112] It should be noted that the shape of the second column 11 is not limited here. For example, on a plane perpendicular to the first direction, the cross-sectional shape of the second column 11 is circular (see Figure 1 and Figure 3 ), elliptical, racetrack, or polygonal (see Figure 2 ).

[0113] The cross-sectional shape of the second pillar 11 refers to the cross-sectional shape of the second pillar 11 cut along a plane perpendicular to the first direction.

[0114] The second column 11 can be used to extrude and form the central hole 200a of the aerosol generating article 200, that is, the cross-sectional shape of the central hole 200a extruded by the second column 11 is circular, elliptical, racetrack-shaped, polygonal or fan-shaped.

For example, at least one of the first body 10, the second body 20 and the third body 30 is provided with a positioning column 100a, and at least another one of them is provided with a positioning hole 100b. The positioning column 100a and the positioning hole 100b cooperate to position the first body 10, the second body 20 and the third body 30.

[0116] That is, one of the first body 10, the second body 20 and the third body 30 may be provided with the positioning column 100a, and the other two may be provided with the positioning hole 100b. Alternatively, one of the first body 10, the second body 20 and the third body 30 may be provided with the positioning hole 100b, and the other two may be provided with the positioning column 100a. Of course, one or more of them may be provided with both the positioning column 100a and the positioning hole 100b.

[0117] Exemplarily, in some embodiments, the first body 10 is provided with a positioning column 100a, and the second body 20 and the third body 30 are both provided with a positioning hole 100b corresponding to the positioning column 100a. By inserting the positioning column 100a of the first body 10 into the positioning holes 100b of the second body 20 and the third body 30, the first body 10, the second body 20 and the third body 30 can be positioned.

[0118] In some other embodiments, the third body 30 may be provided with a positioning column 100a, and the second body 20 and the first body 10 may be provided with a positioning hole 100b corresponding to the positioning column 100a. By inserting the positioning column 100a of the third body 30 into the positioning holes 100b of the second body 20 and the first body 10, the first body 10, the second body 20 and the third body 30 can be positioned.

[0119] In some other embodiments, the second body 20 may be provided with a positioning column 100a, and the third body 30 and the first body 10 may be provided with a positioning hole 100b corresponding to the positioning column 100a. By inserting the positioning column 100a of the second body 20 into the positioning hole 100b of the third body 30 and the first body 10, the first body 10, the second body 20 and the third body 30 can be positioned.
