[0037] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0038] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0039] See also Figure 1 , Figure 1 It is a schematic diagram of an exploded view of a heat-not-burn system 100 provided in an embodiment of the present invention, including a heat-not-burn device 110 and an aerosol product 120. The aerosol product 120 can be inserted into the heat-not-burn device 110, and the heat-not-burn device 110 heats to generate an aerosol. The aerosol product 120 is a consumable and can be replaced after use.

[0040] Please refer to Figure 2 , Figure 3 , Figure 2 yes Figure 1 A partial structural schematic diagram of a heating without burning system 100 is shown. Figure 3 yes Figure 1 The exploded schematic diagram of the heat-not-burn system 100 is shown. The heat-not-burn system 100 includes an aerosol product 120 and a heat-not-burn device 110.

[0041] In a possible embodiment, the heating without burning device 110 includes an upper cover 111 and a lower cover 112, the upper cover 111 is provided with an upper heating groove 1111, and the lower cover 112 is provided with a lower heating groove 1121, and a plurality of heating teeth 310 are respectively provided in the upper heating groove 1111 and the lower heating groove 1121; when the upper heating groove 1111 and the lower heating groove 1121 are aligned, the heating teeth 310 of the upper heating groove 1111 and the lower heating groove 1121 penetrate into the aerosol product 120 from the penetration position on the side of the aerosol product 120 to heat the aerosol substrate.

[0042] Compared with the traditional method of heating by piercing the bottom center of the aerosol product for heating, in the present application, the aerosol product 120 has a piercing position located on its outer peripheral surface, and the heating teeth 310 of the heat-not-burn device 110 can penetrate the aerosol product 120 from the side, so that by setting the position and number of the heating teeth 310, uniform heating of the aerosol product 120 can be achieved.

[0043] In this embodiment, a plurality may refer to two or more than two, which will not be repeatedly described in subsequent embodiments.

[0044] Among them, the cavity formed by the upper heating groove 1111 and the lower heating groove 1121 is the accommodating cavity 150, the heating tooth 310 includes a tooth portion 311 and an end portion 312, the end portion 312 is fixed in the upper heating groove 1111 and the lower heating groove 1121, that is, on the cavity wall of the accommodating cavity 150, and the multiple ends 312 included in the heating tooth 310 are arranged in the length direction of the aerosol product.

[0045] The aerosol product 120 is detachable from the accommodating chamber 150 .

[0046] Among them, the aerosol product 120 includes a protective layer, the protective layer includes a plurality of connected vertical fiber structures 200, the vertical fiber structure 200 includes a skeleton layer 210 and an adhesive layer 220, the adhesive layer 220 is located on the periphery of the skeleton layer 210 and surrounds the skeleton layer 210, the vertical fiber structure 200 extends in the length direction of the aerosol product, and the length direction of the vertical fiber structure 200 is parallel to the length direction of the aerosol product.

[0047] The heating without burning device 110 may be a cylindrical cabin, a rectangular cabin or other variant cabins, which are not limited here. The containing cavity 150 is used to contain aerosol products or other aerosol generated products; Figure 3 As shown, the aerosol product 120 is detachable from the receiving chamber 150 .

[0048] Specifically, the accommodating cavity 150 may be a rectangular cavity or a cavity of other shapes, and the accommodating cavity 150 extends in the length direction of the aerosol product. Exemplarily, the upper heating groove 1111 and the lower heating groove 1121 are both rectangular in profile, and the aerosol product is a rectangular parallelepiped. The rectangular accommodating cavity 150 can more conveniently position the aerosol product and prevent the aerosol product from rolling, so that the heating teeth 310 can be accurately aligned with the corresponding insertion position, thereby piercing the aerosol product.

[0049] The length direction of the aerosol product can refer to Figure 1 or Figure 3 The extension or arrangement direction of the two end portions 312 included in the middle heating tooth 310 can also be understood as the extension direction of the heating without burning system 100. When the heating without burning system 100 includes an aerosol product 120, the length direction of the aerosol product is consistent with the extension direction of the upper heating groove and the extension direction of the lower heating groove.

[0050] See also Figure 4 , Figure 4 yes Figure 1 or Figure 2 Schematic diagram of a scene in which the heating tooth 310 in the heat-not-burn device 110 in the heat-not-burn system 100 pierces the aerosol product 120. As shown in the figure, the tooth portion 311 protrudes from the end portion 312.

[0051] The heating teeth 310 are of a long strip structure, with end portions 312 at both ends fixed to the base 320 , and a middle tooth portion 311 protruding from the end portions 312 to form a pointed end.

[0052] It can be seen that in this embodiment, the upper heating groove 1111 and the lower heating groove 1121 are directly arranged with a plurality of staggered heating teeth 310, the teeth 311 protrude upward and have a pointed end, and the above-mentioned structure of the heating teeth 310 of the heat-not-burn system 100 corresponds to the length direction of the aerosol product and the vertical fiber structure 200 of the aerosol product 120 corresponds to the length direction of the aerosol product, so that the plurality of heating teeth 310 in the cavity wall of the accommodating cavity 150 can easily penetrate the aerosol product 120. The heating teeth 310 can penetrate into the interior of the aerosol product 120 when the upper heating groove 1111 and the lower heating groove 1121 are matched, and the staggered heating teeth penetrate into different parts of the aerosol product 120 from the side, so that the interior of the aerosol product 120 can be better heated.

[0053] Please combine Figure 1 , Figure 3 , Figure 4 , Figure 5 This embodiment provides an aerosol product 120,

[0054] For use with the heat-not-burn device 110, the aerosol product 120 comprises:

[0055] A protective layer, the protective layer comprising circumferentially arranged vertical fiber structures 200, the vertical fiber structures 200 extending in the length direction of the aerosol product, and a piercing position for the heating teeth 310 of the heat-not-burn device 110 to pierce is formed between every two vertical fiber structures 200;

[0056] The aerosol substrate is filled in the containing space 201 surrounded by the protective layer.

[0057] Each vertical fiber structure 200 is closely attached to the vertical fiber structures 200 on the left and right, and is arranged circumferentially in the longitudinal direction of the aerosol product, forming an aerosol product 120 with a hollow interior.

[0058] Among them, the aerosol substrate can include tobacco particles, the filled aerosol substrate can be tobacco or non-tobacco, such as plant aroma substances, the aerosol substrate can be other, which is not limited here, and the shape of the aerosol substrate can be particles, filaments, strips, sheets, etc., which is not limited here.

[0059] It can be seen that in this embodiment, the protective layer is formed by circumferentially arranged vertical fiber structures 200, and the extension direction is the length direction of the aerosol product. Insertion positions are formed between the vertical fibers 200, which is more conducive to the heating teeth 310 to evenly penetrate into the aerosol product 120, so that the aerosol substrate is heated evenly.

[0060] In an optional embodiment, the vertical fiber structure 200 includes a skeleton layer 210 and an adhesive layer 220 , wherein the adhesive layer 220 is located at the periphery of the skeleton layer 210 and wraps the skeleton layer 210 , and the piercing site is formed between adjacent adhesive layers 220 .

[0061] The plane formed by the skeleton layers 210 is called the skeleton layer, and the part formed by the adhesive layer 220 wrapped outside the skeleton layer 210 is called the adhesive layer. The adhesive layer 220 is arranged along the circumferential direction of the adhesive layer.

[0062] It can be seen that in this embodiment, the protective layer structure of the original aerosol product 120 is changed to a protective layer structure formed by bonding multiple fibers in parallel, so that the heating teeth 310 can penetrate the protective layer of the cigarette cartridge and enter the interior of the aerosol product 120, reducing the problem of insufficient heating and improving the user's smoking experience. It can be seen that in this embodiment, the protective layer of the aerosol product 120 is formed by bonding a vertical skeleton layer 210 and an adhesive layer 220 wrapped outside the skeleton layer 210, while maintaining the hardness, the heating teeth 310 can also penetrate the aerosol product 120, so that the aerosol substrate inside the aerosol product 120 is evenly heated.

[0063] In an optional embodiment, at least one layer of the adhesive layer 220 contains multiple layers of the skeleton layer 210 .

[0064] The adhesive layer 220 may be a multi-layer structure, which is melted in the heated mold and fused into one, wrapping around the outer periphery of the skeleton layer 210 .

[0065] The adhesive layer 220 is melted and then adhered along the length direction of the aerosol product.

[0066] It can be seen that in this embodiment, the adhesive layer 220 wraps the skeleton layer 210 to fix and bond the skeleton layer 210, forming a protective layer for the aerosol product 120, and the adhesive layer is bonded along the length direction of the aerosol product, which can be more conducive to the penetration of the heating teeth 310.

[0067] In an optional embodiment, the melting point of the skeleton layer 210 is higher than the melting point of the adhesive layer 220; the skeleton layer 210 is one of polyethylene terephthalate and PP, and the adhesive layer 220 is one of polyamide 6, PE, and polyethylene terephthalate.

[0068] Among them, the above-mentioned material PP is polypropylene (PP), PE is polyethylene (PE); polyethylene terephthalate (PET) includes two types, one is high melting point polyethylene terephthalate, and the other is low melting point polyethylene terephthalate.

[0069] In an optional embodiment, the fiber material of the skeleton layer 210 can be high-melting-point polyethylene terephthalate, and the adhesive layer 220 can be low-melting-point polyethylene terephthalate. In the process of preparing the aerosol product 120, the purpose of melting the adhesive layer 220 first and not melting the skeleton layer 210 can also be achieved.

[0070] In another optional embodiment, the fiber material of the skeleton layer 210 may be polypropylene, and the adhesive layer 220 may be polyethylene. The melting point of polyethylene is lower than that of polypropylene. In the process of preparing the aerosol product 120, the polyethylene of the adhesive layer 220 can be melted first, while the polypropylene of the skeleton layer 210 does not melt.

[0071] In addition, the hardness of the skeleton layer 210 is greater than the hardness of the adhesive layer 220 where the adhesive layer 220 is melted by heat and adheres. When the tooth portion 311 of the heating tooth 310 penetrates the aerosol product 120, it first pierces through the adhesive layer 220 where the adhesive layer 220 is melted by heat and adheres to each other. The stress of the adhesive layer 220 where the adhesive layer 220 is melted by heat and adheres to each other is greater than that of the adhesive layer 220 where no adhesive is formed, and is also greater than that of the skeleton layer 210. The adhesive layer 220 is melted and adheres along the length direction of the aerosol product.

[0072] Specifically, the stress at the bonding position between the bonding layer 220 of each vertical fiber structure 200 and the adjacent bonding layer 220 is the greatest. When the heating tooth 310 penetrates, the bonding position is broken first, and then squeezed and expanded to the surrounding, so that the heating tooth 310 can penetrate the aerosol product 120. After penetration, the heating tooth 310 is fixed in the bonding position of the bonding layer 220.

[0073] In an optional embodiment, the cross-section of the aerosol product 120 along the length direction of the aerosol product is rectangular.

[0074] The aerosol product 120 is shaped as a rectangular cavity composed of a circumferentially arranged skeleton layer 210 and an adhesive layer 220. The cross section in the length direction of the aerosol product is rectangular, and the cross section perpendicular to the length direction of the aerosol product can be square or rectangular, which is not limited here.

[0075] The accommodating cavity 150 for accommodating the aerosol product 120 has the same shape as the aerosol product 120 and can just accommodate the aerosol product 120 .

[0076] It can be seen that in this embodiment, the aerosol product 120 can fit the accommodating cavity 150 of the heat-not-burn device 110 , and the heating teeth 310 can better penetrate into the interior of the aerosol product 120 to heat the interior of the aerosol product 120 .

[0077] It should be noted that Figure 1-Figure 5 The purpose is only to schematically describe the connection relationship between the heat-not-burn device 110 and the aerosol product 120, and it does not specifically limit the connection position, specific structure and quantity of each device. The structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the heat-not-burn system 100.

[0078] In other embodiments of the present invention, the heating without burning system 100 may include Figure 2-Figure 5 More or fewer components may be shown, or some components may be combined or separated, or the components may be arranged differently. Figure 2-Figure 5 The components shown may be implemented in hardware, software or a combination of software and hardware.

[0079] It can be seen that in this embodiment, the hardness of the adhesive layer 220 is lower than that of the skeleton layer 210, and the melting point of the adhesive layer 220 is lower than that of the skeleton layer 210, so that only the adhesive layer 220 will melt during the preparation process and will bond during the cooling process to form the aerosol product 120. The hardness of the bonding position of the adhesive layer 220 is lower than that of other parts, so that the heating teeth 310 can penetrate the aerosol product 120 from the bonding position without damaging the skeleton layer 210, so that the heating teeth 310 can easily penetrate the aerosol product 120 and the structure of the aerosol product 120 will not be damaged.

[0080] In an alternative embodiment, see Figure 3 , Figure 6 , Fig. 9 , the heating teeth 310 on the upper cover 111 are arranged at intervals in the extending direction of the upper heating groove, and the heating teeth 310 on the lower cover 112 are arranged at intervals in the extending direction of the lower heating groove;

[0081] And / or, a plurality of rows of heating teeth 310 are provided in the upper heating groove 1111, and the plurality of rows of heating teeth 310 are arranged side by side in the width direction of the upper heating groove;

[0082] And / or, a plurality of rows of heating teeth 310 are disposed in the lower heating groove 1121, and the plurality of rows of heating teeth 310 are arranged side by side in the width direction of the lower heating groove.

[0083] Among them, the base 320 is connected to the heating teeth 310, and the base 320 is installed with the heating teeth 310. The bases 320 on the upper cover 111 are arranged at intervals in the extension direction of the upper heating groove, and the bases 320 on the lower cover 112 are arranged at intervals in the extension direction of the lower heating groove.

[0084] The width direction of the upper heating groove is parallel to the width direction of the lower heating groove.

[0085] Among them, "and / or" means that the two situations can exist at the same time or separately. For example, multiple rows of heating teeth 310 can be arranged side by side in the width direction of the upper heating groove 1111, or multiple rows of heating teeth 310 can be arranged side by side in the width direction of the upper heating groove; multiple rows of heating teeth 310 can be arranged side by side in the width direction of the lower heating groove 1121, or multiple rows of heating teeth 310 can be arranged side by side in the width direction of the lower heating groove; multiple rows of heating teeth 310 can be arranged side by side only in the upper heating groove 1111, or multiple rows of heating teeth 310 can be arranged side by side only in the lower heating groove 1121. That is, the number of heating teeth 310 provided in the upper heating groove 1111 and the number of heating teeth 310 provided in the lower heating groove 1121 may not be equal, and the number of rows of heating teeth 310 may not be equal. There is a case where the upper heating groove 1111 is provided with multiple rows of heating teeth 310 while the lower heating groove 1121 is provided with only one row of heating teeth 310, and there is also a case where the upper heating groove 1111 is provided with one row of heating teeth 310 while the lower heating groove 1121 is provided with multiple rows of heating teeth 310. The above description of multiple rows is not used as a limitation on the number, and multiple rows means that it can be two rows or more, which is not limited here.

[0086] The number of heating teeth 310 in each row may be different, and the specific number is not limited.

[0087] It can be seen that in the embodiment of the present invention, the heating teeth 310 are arranged at intervals in the extension direction of the upper heating groove and the lower heating groove, and multiple rows or only one row can be set in the width direction of the upper heating groove and the lower heating groove; it is beneficial to insert the heating teeth into the aerosol product and also beneficial to uniformly heat the aerosol substrate. In an optional embodiment, when the upper heating groove 1111 and the lower heating groove 1121 are aligned, the heating teeth 310 of the upper heating groove 1111 and the heating teeth 310 of the lower heating groove 1121 are staggered in the extension direction of the upper heating groove.

[0088] Wherein, the extension direction of the upper heating groove is parallel to the extension direction of the lower heating groove.

[0089] Among them, the positions of the heating teeth 310 of the upper heating groove 1111 and the heating teeth 310 of the lower heating groove 1121 in the extension direction of the upper heating groove do not correspond, and the position of the tooth portion 311 of the heating teeth 310 of the upper heating groove 1111 corresponds to between the two bases 320 of the two heating teeth 310 of the lower heating groove 1121.

[0090] It can be seen that in the embodiment of the present invention, after the heating teeth 310 of the upper heating groove 1111 and the heating teeth 310 of the lower heating groove 1121 are aligned and inserted into the aerosol product, the upper and lower heating teeth 310 are staggered with each other, which is more conducive to uniform heating of the aerosol substrate.

[0091] Please combine Figure 6 , Figure 7 , Figure 8 ,in Figure 6 yes Figure 1 The schematic structural diagram of an angle of the upper cover 111 of the heat without combustion device 110 of the heat without combustion system 100 shown in FIG. Figure 7 yes Figure 1 Another schematic cross-sectional view of the upper cover 111 of the heat without combustion device 110 of the heat without combustion system 100 is shown; Figure 8 yes Figure 1 A perspective structural diagram of an upper cover 111 of a heat without combustion device 110 of a heat without combustion system 100 is shown.

[0092] In the upper cover 111, the heating teeth 310 are distributed and fixed on the groove wall of the upper heating groove 1111. The heating teeth 310 can be made of conductive materials such as nickel-chromium alloy, iron-chromium-aluminum alloy, stainless steel, etc. The heating teeth 310 are in the shape of long thin strips and can penetrate the aerosol product 120. The heating teeth 310 are arranged vertically in the length direction of the aerosol product and are arranged horizontally and staggered in the width direction of the upper heating groove to achieve the effect of being evenly arranged in the accommodating cavity 150. The base 320 for fixing the heating teeth 310 is made of low-resistance materials such as copper alloy, silver-palladium alloy, and pure gold with excellent conductivity. The base 320 is fixed to the groove wall of the upper heating groove 1111 and the lower heating groove 1121, and the end 312 of the heating teeth 310 is fixed by welding. The middle part of the heating teeth 310 protrudes from the end 312 at both ends to form a tooth part 311 for inserting the aerosol product 120.

The power module 330 is fixedly connected to the power supply slot 410, and the base 320 is connected to the control module 340 and the power module 330 through a connecting wire 350.

[0097] It can be seen that in the present embodiment, the original heating component is replaced with the heating teeth 310, and they are evenly arranged in the upper heating groove 1111. Each heating tooth 310 can be energized individually, so that the aerosol product 120 is heated more evenly during heating, so that the aerosol substrate inside the aerosol product 120 is fully heated, thereby improving the heating efficiency, reducing the situation of insufficient heating, and enhancing the user's puffing experience.

[0099] In the lower cover 112, the heating teeth 310 are distributed and fixed on the groove wall of the lower heating groove 1121. The heating teeth 310 can be made of conductive materials such as nickel-chromium alloy, iron-chromium-aluminum alloy, stainless steel, etc. The heating teeth 310 are in the shape of long thin strips. The heating teeth 310 are arranged vertically in the length direction of the aerosol product and are arranged horizontally in a staggered manner in the width direction of the lower heating groove to achieve the effect of being evenly arranged in the accommodating cavity 150. The base 320 for fixing the heating teeth 310 is made of low-resistance materials such as copper alloy, silver-palladium alloy, and pure gold with excellent conductivity. The base 320 is fixed to the groove wall of the lower heating groove 1121, and the ends 312 of the heating teeth 310 are fixed by welding. The middle part of the heating teeth 310 protrudes from the ends 312 at both ends to form a tooth part 311 for inserting the aerosol product 120.

[0100] The number of the heating teeth 310 is not limited, and the end 312 of the heating tooth 310 is fixedly connected to the base 320 , and the base 320 is fixedly connected to the groove wall of the lower heating groove 1121 .

[0101] The two bases 320 correspond to one heating tooth 310 , and the two ends 312 of each heating tooth 310 correspond to one base 320 .

[0102] The heating teeth 310 are made of a strong material with high hardness and are not easily deformed.

[0103] The charging column 430 is connected to the outside, and can be connected to the user's charger to supply power to the power module 330 .

[0104] The power module 330 supplies power to the heating teeth 310 , and the control module 340 controls the heating teeth 310 to be turned on.

[0105] The rotating shaft 113 connects the upper cover 111 and the lower cover 112 , and the upper cover rotates around the axial direction of the rotating shaft 113 to open and close.

[0106] It can be seen that in this embodiment, the original heating component is replaced with heating teeth 310, and they are evenly arranged in the lower heating groove 1121. Each heating tooth 310 can be energized separately, so that the aerosol product 120 is heated more evenly during heating; and the rotating shaft 113 is used to connect the upper cover 111 and the lower cover 112, so that the user can disassemble and assemble the aerosol product 120 conveniently; the current of the heating teeth 310 is turned on and off by the control module 340, and then the heating time of the heating teeth 310 is controlled, so that the heating teeth 310 are heated according to the settings during heating, so that the aerosol substrate inside the cigarette cartridge is fully heated, thereby improving the heating efficiency, reducing the situation of insufficient heating, and enhancing the user's smoking experience.

[0107] In an optional embodiment, please refer to Figure 1 and Figure 2When the upper cover 111 and the lower cover 112 are tightly closed, the power supply slot 410 fits with the conductive column 420, the circuit is turned on, the power supply module 330 supplies power to the heating teeth 310 of the upper cover 111 while supplying power to the heating teeth 310 of the lower cover 112, and the control module 340 controls the heating teeth 310 of the upper cover 111 and the lower cover 112 at the same time.

[0108] It can be seen that by controlling the module 340 to switch the current of the heating teeth 310 on and off, and then controlling the heating time of the heating teeth 310, the heating teeth 310 are heated according to the settings during heating, so that the aerosol substrate inside the cigarette cartridge is fully heated, thereby improving the heating efficiency, reducing the situation of insufficient heating, and improving the user's smoking experience.

[0109] Among them, the conductive column 420 is arranged in a direction perpendicular to the extension direction of the lower cover 112, that is, the length direction of the aerosol product; the heating teeth are arranged in directions perpendicular to the extension directions of the lower heating groove 1121 and the upper heating groove 1111 respectively.

[0110] In an alternative embodiment, see Figure 1-3 picture, Figure 6-Figure 11 The upper heating groove 1111 and the lower heating groove 1121 are fixedly connected with a plurality of bases 320, and heating teeth 310 are fixedly installed on the bases 320. Both ends of the heating teeth 310 are welded and fixed to the bases 320. The bases 320 correspond to both ends of the heating teeth 310 one by one, and the heating teeth 310 are evenly distributed in the upper heating groove 1111 and the lower heating groove 1121.

[0111] The heating without burning device 110 is fixedly connected with a suction nozzle 130, and the suction nozzle 130 is in a prism shape.

[0112] Among them, two protruding cylindrical A magnets 114 are arranged on the inner side of the upper cover 111, on both sides of the upper heating groove 1111, near the position of the suction nozzle 130, and two cylindrical grooved B magnets 115 are arranged at the corresponding position of the lower cover 112, and the A magnet 114 and the B magnet 115 can be attracted. The A magnet 114 and the B magnet 115 are attracted, so that the upper cover 111 and the lower cover 112 can be tightly fitted and locked, and the suction nozzle 130 is connected to the lower cover 112. The suction nozzle 130 is made of silicone material, and openings are arranged at both ends of the suction nozzle 130. The openings at both ends pass through the suction nozzle 130 and communicate with the lower heating groove 1121 to form a channel 140. The channel 140 allows the airflow to reach the outside from the cigarette cartridge.

[0113] When the upper cover 111 and the lower cover 112 are closed, the A magnet 114 and the B magnet 115 are attracted to each other, the suction nozzle 130 is made of silicone material and is tightly closed with the upper cover 111 and the lower cover 112, and the channel 140 in the suction nozzle 130 forms a suction channel.

[0114] Among them, a plurality of protruding conductive pillars 420 are arranged at the inner side of the upper cover 111 near the rotating shaft 113, and the conductive pillars 420 are arranged and installed in the width direction of the upper heating groove. The number of conductive pillars 420 can be 6 or other numbers, which are not limited here; a plurality of concave power supply slots 410 are arranged at the corresponding positions on the inner side of the lower cover 112, and the number of power supply slots 410 is the same as the number of conductive pillars 420, and they correspond one to one. The rotating shaft 113 is used to fix the upper cover 111 and the lower cover 112, and the upper cover 111 and the lower cover 112 are rotatably connected, such as hinged connection.

[0115] Among them, multiple conductive pillars 420 correspond one by one to the power supply slot 410. After the upper cover 111 and the lower cover 112 are fitted together, the suction nozzle 130 makes the upper cover 111 and the lower cover 112 fit tightly together, and the conductive pillars 420 and the power supply slot 410 also fit tightly together. The current forms a path through the conductive pillars 420 and the power supply slot 410. The current can be transmitted to the base 320 through the conductive pillars 420 and the power supply slot 410, and then to the heating teeth 310, so that the heating teeth 310 are powered on and heated.

[0116] The base 320 is connected to the wire, and each heating tooth 310 corresponds to the wire and can be powered individually.

[0117] It can be seen that in the embodiment of the present invention, the heating tooth structure of the heating without burning system corresponds to the vertical fiber structure of the aerosol product 120, so that the multiple heating teeth in the upper heating groove and the lower heating groove can easily penetrate the aerosol product 120 and penetrate into the interior of the aerosol product 120, which is beneficial to uniformly heat the aerosol substrate of the aerosol product 120 and improve the heating efficiency.

[0118] See also Fig.12 , Fig.12 : is a cross-sectional schematic diagram of a mold provided by an embodiment of the present invention. The present application embodiment provides a mold 500, including:

[0119] An inner layer mold 510 and an outer layer mold 520, wherein a rectangular ring-shaped cavity is formed between the inner layer mold 510 and the outer layer mold 520, and the cavity is used to place the fiber structure raw material, and the inner layer mold 510 and the outer layer mold 520 can both heat the fiber structure raw material in the cavity to shape the fiber structure raw material into the vertical fiber structure 200.

[0120] The inner mold 510 and the outer mold 520 are concentrically arranged to ensure that the thickness of the rectangular ring-shaped cavity between the inner mold 510 and the outer mold 520 is uniform, that is, the thickness of the protective layer formed by the vertical fiber structure 200 processed by the mold is uniform.

[0121] Among them, the interior of the inner layer mold 510 can be solid or hollow. The solid inner layer mold or the hollow inner layer mold both have a heating function and do not affect the heating effect. There is no limitation on whether the inner layer mold is solid or hollow.

[0122] The protective layer formed after the mold 500 is processed is in the shape of a hollow rectangle with two ends open.

[0123] It can be seen that in this embodiment, the rectangular ring-shaped cavity formed between the inner mold 510 and the outer mold 520 can heat the raw material of the vertical fiber structure 200 to form a circumferential rectangular ring-shaped protective layer with openings at both ends. The inner mold 510 and the outer mold 520 both have a heating function to achieve more uniform heating of the raw material of the vertical fiber structure.

[0124] In a possible embodiment, at least one of the inner mold 510 and the outer mold 520 is made of Teflon or stainless steel.

[0125] Among them, Teflon or stainless steel are materials with good heat conductivity. In practical applications, the outer mold 520 can be made of Teflon, while the inner mold 510 can be made of other materials; the outer mold 520 can be made of stainless steel, while the inner mold 510 can be made of other materials; the outer mold 520 can be made of other materials, while the inner mold 510 can be made of Teflon; the outer mold 520 can be made of other materials, while the inner mold 510 can be made of stainless steel. The above other materials are all materials with heat conductivity, and the specific materials are not limited here.

[0126] For example, in the process of preparing the aerosol product 120, the inner layer mold 510 and the outer layer mold 520 are heated at the same time, so that the adhesive layer 220 is heated. When the temperature reaches the melting point of the adhesive layer 220, the adhesive layer 220 melts first, and the melted adjacent adhesive layers 220 adhere to each other. After cooling, the adjacent adhesive layers 220 adhere to form a whole. During this process, the skeleton layer 210 will not melt.

[0127] It can be seen that in this embodiment, both the inner mold 510 and the outer mold 520 have a heat-conducting function, and one of the layers is made of a good heat-conducting material, which is conducive to more uniform heating of the vertical fiber structure material to form a uniform and strong protective layer.
