Description

Aerosol products, heat-not-burn systems and molds

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 14, 2023, with application number 2023115144669 and application name “A Aerosol Product, Heating-Not-Burn System and Mold”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of heat-not-burn technology, and in particular to an aerosol product, a heat-not-burn system, and a mold. Background Art

[0003] Heat-not-burn (HBB) devices primarily heat aerosol products at temperatures below those that would cause combustion, producing an aerosol containing tobacco or non-tobacco ingredients for consumer use. The design of the heating element in HBB devices must fully consider the heating temperature balance while minimizing energy waste. HBB devices typically utilize a metal circuit printed on ceramic as the heating element. When powered on, the Joule effect generates heat to heat the cartridge.

[0004] Traditional aerosol products usually wrap the mouthpiece and the smoking section together with moisture-proof wrapping material. The heating element of the heat-not-burn device is inserted from the bottom center of the aerosol product to heat the aerosol substrate around the heating element. However, this heating method will cause the heating temperature of the aerosol substrate in the center of the smoking section to be higher than that in the peripheral areas, and it is impossible to ensure the uniform heating of the aerosol substrate in the smoking section.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide an aerosol product, a heat-without-combustion system, and a mold.

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0037] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly attached to the other component or there may be a central component. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0038] It should be noted that the concepts of "first" and "second" mentioned in this 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.

[0039] The embodiments of the present application are described below with reference to the accompanying drawings.

[0040] Please refer to Figure 1, which is a schematic diagram of an exploded view of a heat-not-burn system 100 provided in an embodiment of the present application, 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.

[0041] Please refer to Figures 2 and 3. Figure 2 is a partial structural diagram of the heat-not-burn system 100 shown in Figure 1, and Figure 3 is an exploded schematic diagram of the heat-not-burn system 100 shown in Figure 1. The heat-not-burn system 100 includes an aerosol product 120 and a heat-not-burn device 110.

[0042] 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 are inserted into the insertion position on the side of the aerosol product 120, located inside the aerosol product 120, to heat the aerosol substrate.

[0043] Compared with the traditional heating element piercing from the bottom center of the aerosol product for heating, the aerosol product 120 of the present application has a piercing position located on its outer peripheral surface, and the heating teeth 310 of the heating without burning device 110 can be pierced from the side of the aerosol product 120, so that by setting the position and number of the heating teeth 310, uniform heating of the aerosol product 120 can be achieved.

[0044] In this embodiment, a plurality may refer to two or more than two, which will not be repeatedly described in subsequent embodiments.

[0045] Among them, the cavity formed by the upper heating groove 1111 and the lower heating groove 1121 is the accommodating cavity 150, and 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. The multiple ends 312 included in the heating tooth 310 are arranged in the length direction of the aerosol product.

[0046] The aerosol product 120 is detachable from the accommodating cavity 150 .

[0047] 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.

[0048] The heat-not-burn device 110 may be a cylindrical, rectangular, or other container, and is not limited thereto. The receiving chamber 150 is used to receive an aerosol product or other aerosol-generating product. As shown in FIG3 , the aerosol product 120 is removable from the receiving chamber 150 .

[0049] The accommodating cavity 150 can be a rectangular cavity or a cavity of other shapes, and the accommodating cavity 150 extends in the longitudinal direction of the aerosol product. For example, the upper heating groove 1111 and the lower heating groove 1121 both have rectangular outlines, and the aerosol product is a rectangular parallelepiped. The rectangular accommodating cavity 150 can more easily position the aerosol product and prevent it from rolling, thereby allowing the heating teeth 310 to accurately align with the corresponding insertion position and penetrate the aerosol product.

[0050] Among them, the length direction of the aerosol product may refer to the extension or arrangement direction of the two end portions 312 included in the heating teeth 310 as shown in Figure 1 or Figure 3, and 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.

[0051] Please refer to Figure 4, which is a schematic diagram of a scene in which the heating tooth 310 of the heat-not-burn device 110 in the heat-not-burn system 100 in Figure 1 or Figure 2 pierces the aerosol product 120. As shown in the figure, the tooth portion 311 protrudes from the end portion 312.

[0052] The heating teeth 310 are of an elongated 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.

[0053] As can be seen, 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 are upwardly protruding and have pointed tips. The aforementioned structure of the heating teeth 310 of the heat-not-burn system 100 corresponds to the longitudinal direction of the aerosol product and is parallel to the longitudinal direction of the vertical fiber structure 200 of the aerosol product 120. This makes it easy for the multiple heating teeth 310 in the wall of the accommodating cavity 150 to penetrate the aerosol product 120. When the upper heating groove 1111 and the lower heating groove 1121 are aligned, the heating teeth 310 can penetrate the interior of the aerosol product 120. The staggered heating teeth penetrate different parts of the aerosol product 120 from the side, which can better heat the interior of the aerosol product 120.

[0054] 1, 3, 4 and 5, this embodiment provides an aerosol product 120.

[0055] For use with the heat-not-burn device 110, the aerosol product 120 includes:

[0056] A protective layer comprising circumferentially arranged vertical fiber structures 200 extending in the longitudinal direction of the aerosol product, with insertion sites for the heating teeth 310 of the heat-not-burn device 110 to penetrate between every two vertical fiber structures 200;

[0057] The aerosol substrate is filled in the containing space 201 surrounded by the protective layer.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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 on the periphery of the skeleton layer 210 and wraps the skeleton layer 210 , and the puncture sites are formed between adjacent adhesive layers 220 .

[0062] The plane formed by the skeleton layers 210 is called the skeleton layer, and the portion formed by the adhesive layer 220 wrapped around the skeleton layer 210 is called the adhesive layer. The adhesive layer 220 is arranged along the circumferential direction of the adhesive layer.

[0063] As can be seen, in this embodiment, the protective layer structure of the original aerosol product 120 is replaced with a protective layer structure composed of multiple fibers bonded in parallel. This allows the heating teeth 310 to 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 puffing experience. As can be seen, 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 around the skeleton layer 210. While maintaining its rigidity, it also allows the heating teeth 310 to penetrate the aerosol product 120, thereby evenly heating the aerosol substrate inside the aerosol product 120.

[0064] In an optional embodiment, multiple layers of the skeleton layer 210 are wrapped in at least one layer of the adhesive layer 220 .

[0065] The adhesive layer 220 may be a multi-layer structure, which is melted in the heated mold and fused into one body, wrapping around the outer periphery of the skeleton layer 210 .

[0066] The adhesive layer 220 is melted and then adhered along the length direction of the aerosol product.

[0067] It can be seen that in this embodiment, the adhesive layer 220 wraps the skeleton layer 210 to achieve the function of fixing and bonding 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] Furthermore, the hardness of the skeleton layer 210 is greater than the hardness of the adhesive layer 220 where it is melted and adhered. When the teeth 311 of the heating teeth 310 penetrate the aerosol product 120, they first penetrate the adhesive layer 220 where it is melted and adhered to each other. The stress at the adhesive layer 220 where it is melted and adhered is greater than that at the unadhered portion of the adhesive layer 220 and greater than that of the skeleton layer 210. The adhesive layer 220, after melting, adheres along the length of the aerosol product.

[0073] Among them, 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 squeezed and expanded to the surrounding area, 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.

[0074] In an optional embodiment, the cross-section of the aerosol product 120 along the length direction of the aerosol product is rectangular.

[0075] 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 longitudinal direction of the aerosol product is rectangular, and the cross section perpendicular to the longitudinal direction of the aerosol product can be square or rectangular, which is not limited here.

[0076] 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 .

[0077] 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 .

[0078] It should be noted that Figures 1-5 are intended to schematically illustrate the connection between the heat-not-burn device 110 and the aerosol product 120, and do not specifically limit the connection location, specific structure, or quantity of each device. Furthermore, the illustrated structure of the embodiments of this application does not constitute a specific limitation on the heat-not-burn system 100.

[0079] In other embodiments of the present application, the heat-not-burn system 100 may include more or fewer components than those shown in Figures 2-5, or may combine or separate certain components, or may have different component arrangements. The components shown in Figures 2-5 may be implemented in hardware, software, or a combination of software and hardware.

[0080] As can be seen, in this embodiment, the adhesive layer 220 has a lower hardness than the frame layer 210, and the melting point of the adhesive layer 220 is lower than that of the frame layer 210. This causes the adhesive layer 220 to melt during the preparation process and to bond during the cooling process, forming the aerosol product 120. The hardness of the adhesive layer 220 at the bonding location is lower than that of other locations, allowing the heating teeth 310 to penetrate the aerosol product 120 at the bonding location without damaging the frame layer 210. This makes it easy for the heating teeth 310 to penetrate the aerosol product 120 without damaging the structure of the aerosol product 120.

[0081] In an optional embodiment, referring to Figures 3, 6, and 9, the heating teeth 310 on the upper cover 111 are arranged at intervals in the extension direction of the upper heating groove, and the heating teeth 310 on the lower cover 112 are arranged at intervals in the extension direction of the lower heating groove; 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; and / or, a plurality of rows of heating teeth 310 are provided 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.

[0082] 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.

[0083] The width direction of the upper heating tank is parallel to the width direction of the lower heating tank.

[0084] Here, "and / or" indicates that the preceding and following situations can exist simultaneously or separately. For example, multiple rows of heating teeth 310 can be arranged side by side in the width direction of the upper heating tank 1111, or multiple rows of heating teeth 310 can be arranged side by side in the width direction of the upper heating tank; multiple rows of heating teeth 310 can be arranged side by side in the width direction of the lower heating tank 1121, or multiple rows of heating teeth 310 can be arranged side by side in the width direction of the lower heating tank; multiple rows of heating teeth 310 can be arranged side by side only in the upper heating tank 1111, or multiple rows of heating teeth 310 can be arranged side by side only in the lower heating tank 1121. That is, the number of heating teeth 310 provided in the upper heating tank 1111 and the number of heating teeth 310 provided in the lower heating tank 1121 may be different, and the number of rows of heating teeth 310 may be different. In some cases, the upper heating tank 1111 may be provided with multiple rows of heating teeth 310 while the lower heating tank 1121 may be provided with only one row of heating teeth 310. In other cases, the upper heating tank 1111 may be provided with one row of heating teeth 310 while the lower heating tank 1121 may be provided with multiple rows of heating teeth 310. The above description of "multiple rows" is not intended to limit the number. "Multiple rows" means that the number of rows can be two or more, and this is not limited here.

[0085] The number of heating teeth 310 in each row may be different, and the specific number is not limited.

[0086] It can be seen that in the embodiment of the present application, 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; this is conducive to inserting the heating teeth into the aerosol product, and is also conducive to uniform heating of the aerosol substrate.

[0087] 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] 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 application, after the upper cover 111 and the lower cover 112 are aligned and inserted into the aerosol product, the upper and lower heating teeth 310 of the upper heating groove 1111 and the heating teeth 310 of the lower heating groove 1121 are staggered with each other, which is more conducive to uniform heating of the aerosol substrate.

[0091] Please refer to Figures 6, 7 and 8, where Figure 6 is a structural schematic diagram of the upper cover 111 of the heating without combustion device 110 of the heating without combustion system 100 shown in Figure 1 at one angle, and Figure 7 is a cross-sectional structural schematic diagram of the upper cover 111 of the heating without combustion device 110 of the heating without combustion system 100 shown in Figure 1 at another angle; and Figure 8 is a perspective structural diagram of the upper cover 111 of the heating without combustion device 110 of the heating without combustion system 100 shown in Figure 1.

[0092] Within the upper cover 111, heating teeth 310 are distributed and fixed to the walls of the upper heating tank 1111. The heating teeth 310 can be made of a conductive material such as nickel-chromium alloy, iron-chromium-aluminum alloy, or stainless steel. They are long, thin strips designed to penetrate the aerosol product 120. The heating teeth 310 are arranged vertically along the length of the aerosol product and staggered horizontally across the width of the upper heating tank to ensure uniform arrangement within the accommodating cavity 150. The bases 320, which secure the heating teeth 310, are made of a low-resistance material such as highly conductive copper alloy, silver-palladium alloy, or pure gold. The bases 320 are fixed to the walls of the upper and lower heating tanks 1111 and 1121. The ends 312 of the heating teeth 310 are welded to the bases. The middle portion of the heating teeth 310 protrudes beyond the ends 312, forming teeth 311 for insertion into the aerosol product 120.

[0093] The number of the heating teeth 310 is not limited. The end portions 312 of the heating teeth 310 are fixedly connected to the base 320 , and the base 320 is fixedly connected to the wall of the upper heating groove 1111 .

[0094] 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 .

[0095] The heating teeth 310 are made of a strong material with high hardness and are not easily deformed.

[0096] A PCB (Printed Circuit Board) bridge board 360 is welded inside the upper cover 111 and positioned beneath the base 320. The base 320 is connected to the PCB bridge board 360 via a connecting wire 350, which in turn connects to the conductive posts 420 via the PCB bridge board 360. The lower cover 112 houses the power module 330, control module 340, and charging posts 430. 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 power module 330 via a connecting wire 350.

[0097] 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 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.

[0098] Please refer to Figures 4, 9, 10 and 11, where Figure 4 is a schematic diagram of a scene in which the heating teeth 310 in the heat-not-burn device 110 shown in Figure 1 or 2 pierce the aerosol product 120; Figure 9 is a structural schematic diagram of the lower cover 112 of the heat-not-burn device 110 of the heat-not-burn system 100 shown in Figure 1 at one angle; Figure 10 is a schematic cross-sectional structural diagram of the lower cover 112 of the heat-not-burn device 110 of the heat-not-burn system 100 shown in Figure 1 at another angle; and Figure 11 is a perspective structural diagram of the lower cover 112 of the heat-not-burn device 110 of the heat-not-burn system 100 shown in Figure 1;

[0099] In the lower cover 112, heating teeth 310 are distributed and fixed to the walls of the lower heating tank 1121. The heating teeth 310 can be made of a conductive material such as nickel-chromium alloy, iron-chromium-aluminum alloy, or stainless steel. They are in the shape of long, thin strips, arranged vertically along the length of the aerosol product and staggered horizontally across the width of the lower heating tank to achieve uniform arrangement within the accommodating cavity 150. The base 320, which secures the heating teeth 310, is made of a low-resistance material such as an extremely conductive copper alloy, silver-palladium alloy, or pure gold. The base 320 is fixed to the walls of the lower heating tank 1121 and welded to the ends 312 of the heating teeth 310. The middle portion of the heating teeth 310 protrudes beyond the ends 312, forming a tooth portion 311 for insertion into the aerosol product 120.

[0100] The number of the heating teeth 310 is not limited. The end portions 312 of the heating teeth 310 are fixedly connected to the base 320 , and the base 320 is fixedly connected to the 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, which is convenient for users to disassemble and assemble the aerosol product 120; the current of the heating teeth 310 is turned on and off by the control module 340, thereby controlling the heating time of the heating teeth 310, 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 Figures 1 and 2 in combination. When the upper cover 111 and the lower cover 112 are tightly closed, the power supply slot 410 is in contact with the conductive column 420, the circuit is turned on, and 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 turn on and off the current of the heating teeth 310, 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 optional embodiment, referring to Figures 1-3 and Figures 6-11, the upper heating tank 1111 and the lower heating tank 1121 are fixedly connected with multiple bases 320, and heating teeth 310 are fixedly mounted on the bases 320. The two ends of the heating teeth 310 are welded and fixed to the bases 320. The bases 320 correspond to the two ends of the heating teeth 310 one by one, and the heating teeth 310 are evenly distributed in the upper heating tank 1111 and the lower heating tank 1121.

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

[0112] Two protruding cylindrical A magnets 114 are provided 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. Two cylindrically recessed B magnets 115 are provided at the corresponding position of the lower cover 112. The A magnets 114 and B magnets 115 can be attracted to each other. The attraction of the A magnets 114 and B magnets 115 can make the upper cover 111 and the lower cover 112 fit tightly and lock. The suction nozzle 130 is connected to the lower cover 112. The suction nozzle 130 is made of silicone material and has openings at both ends. 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 airflow from the cigarette cartridge to the outside.

[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, and the suction nozzle 130 is made of silicone material and is tightly closed with the upper cover 111 and the lower cover 112. The channel 140 in the suction nozzle 130 forms a suction channel.

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

[0115] Among them, multiple conductive pillars 420 correspond one-to-one to the power supply slots 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 slots 410 also fit tightly together. The current forms a path through the conductive pillars 420 and the power supply slots 410. The current can be transmitted through the conductive pillars 420 and the power supply slots 410 to the base 320, and then to the heating teeth 310, so that the heating teeth 310 are energized and heated.

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

[0117] It can be seen that in the embodiment of the present application, the heating tooth structure of the heat-not-burn 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 heating the aerosol substrate of the aerosol product 120 and improving the heating efficiency.

[0118] Referring to FIG12 , FIG12 is a schematic cross-sectional view of a mold provided in an embodiment of the present application. The present application embodiment provides a mold 500 comprising:

[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. 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. Both the solid inner layer mold and the hollow inner layer mold have heating function, which does not affect its 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, forming a circumferential rectangular ring-shaped protective layer with openings at both ends. The inner mold 510 and the outer mold 520 both have heating functions 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] Teflon or stainless steel are materials with good thermal 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; or the outer mold 520 can be made of other materials, while the inner mold 510 can be made of stainless steel. These other materials are all thermally conductive, 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, the inner mold 510 and the outer mold 520 both have heat conduction functions, 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 raw material to form a uniform and strong protective layer.
