Non-combustion / heating type aerosol generator and aerosol generation system containing the same

Abstract

The present invention discloses a non-combustion and heating type aerosol generating device, which includes an apparatus body (1), a container tube (2) located in the body (1), and a heating section (3). The container tube (2) has a bottom wall (22), and the heating section (3) has a bottom end (32). The bottom end (32) of the heating section (3) has a vertical height higher than the height of the bottom wall (22) of the container tube (2). This ensures that the area of ​​the bottom end side of the aerosol generating substrate of the aerosol generating product is not surrounded by the heating section by making the vertical height of the bottom end (32) of the heating section (3) higher than the end face on one side of the aerosol generating substrate of the aerosol generating product. In this way, if the temperature of this section is low so that almost no aerosol is generated, the problem of the aerosol in this section condensing and flowing out after inhalation is stopped and contaminating the bottom wall of the heating tube can be avoided. In the aerosol-generating product of the present invention, the aerosol-generating substrate section (82) further comprises a tight section (81) at one end remote from the filter section (84).

Description

Technical Field

[0001] The present invention patent relates to the technical field of the production of low-temperature non-combustion heating aerosol generation devices, and specifically relates to non-combustion heating type aerosol generation devices and aerosol generation systems including the same.

Background Art

[0002] Generally, the heating temperature of the non-combustion heating aerosol generation substrate is between 250°C and 350°C. Compared with conventional combustible cigarettes, non-combustion heating aerosol generation products can significantly reduce the harm caused by harmful substances in the aerosol generation substrate to smokers while maintaining the taste of conventional cigarettes. In addition, since the decomposition process due to high-temperature combustion does not occur, the release of tar and harmful substances in the aerosol generation substrate is reduced, and the harm of passive smoking can be significantly reduced.

[0003] Currently, heating technologies for aerosol-generating products typically include resistance heating or electromagnetic heating. Heating elements usually take the form of tubular heating tubes that surround and heat the aerosol-generating product, or tip-shaped / pin-shaped heating tips / pins that are inserted into the aerosol-generating product for heating. In resistance heating, the resistive lines on the heating element generate heat when energized, heating the aerosol-generating product. In electromagnetic heating, the heating element generates an electric current by sensing a magnetic field, generating heat and heating the aerosol-generating product. Conventional non-combustion, heating-type aerosol-generating products include a filter section for inhalation at the user's mouth and an aerosol-generating substrate section separated from the filter section. Airflow can enter the aerosol-generating product from the end face of the aerosol-generating substrate section and exit from the end face of the filter section. In this case, the following problems arise. In other words, regardless of whether the aerosol-generating substrate is heated by a heating tube or a heating tip / heating pin, even when the user is not inhaling, a small amount of cold air enters the aerosol-generating substrate section from the end face. As a result, the small amount of atomized aerosol in the aerosol-generating substrate section comes into contact with the cold air and condenses, and the resulting liquid flows out from the end face of the aerosol-generating substrate section, contaminating the device. In addition, when the user inhales, the negative pressure in the aerosol-generating substrate section decreases, causing the aerosol to flow into the filter section. However, when the user is not inhaling, there is no suction force from the user, so the negative pressure causes a small amount of aerosol to flow from the filter section towards the aerosol-generating substrate section. If condensation occurs, the resulting liquid flows out from the end face of the aerosol-generating substrate section, contaminating the device.

[0004] In addition, in conventional non-combustion, heated aerosol generators that heat the aerosol-generating product using a heating tube, the bottom end of the heating tube is usually aligned with the bottom end of the aerosol-generating substrate, and the bottom wall surface of the heating tube supports the bottom end surface of the aerosol-generating substrate. In this case, the heating tube heats the bottom end of the aerosol-generating substrate (the end separated from the filter). Therefore, after suction is stopped, the aerosol generated by atomization at the bottom end of the aerosol-generating substrate section cannot be suctioned in time, and it condenses and flows out from the end face of the aerosol-generating substrate section, contaminating the bottom of the heating tube. Furthermore, if outside air is also entering from the end face of the aerosol-generating substrate section at this time, the aerosol generated by atomization at the bottom end of the aerosol-generating substrate section is pre-cooled, making it even easier to condense, and it flows out and contaminates the bottom wall of the heating tube.

[0005] Therefore, avoiding the re-condensation of atomized aerosols is one of the important methods for preventing equipment contamination. [Overview of the project] [Problems that the invention aims to solve]

[0006] To solve the above problems, we propose the present invention. [Means for solving the problem]

[0007] The present invention provides a non-combustion, heating-type aerosol generating apparatus that includes a main body 1, a storage cylinder 2 located within the main body 1 for containing an aerosol generating product, and a heating unit 3 used for heating the aerosol generating product to generate an aerosol.

[0008] The containment cylinder 2 includes a top opening 21 for inserting an aerosol-generating product and a bottom wall 22 facing the top opening 21. The aerosol-generating product is inserted through the top opening 21 and contained within the containment cylinder 2.

[0009] The heating section 3 includes an upper end 31 and a bottom end 32 on the opposite side of the upper end 31.

[0010] The bottom end 32 of the heating section 3 has a vertical height that is higher than the height of the bottom wall 22 of the storage cylinder 2. The purpose of limiting the vertical height of the bottom end 32 of the heating section 3 to be higher than the height of the bottom wall 22 of the storage cylinder 2 is to ensure that after the storage cylinder 2 is no longer filled with aerosol-generating products, the vertical height of the bottom end 32 of the heating section 3 is higher than one end face of the aerosol-generating substrate of the aerosol-generating product.

[0011] Preferably, the heating section 3 is a heating tube provided separately from the containment cylinder 2, and together with the containment cylinder 2, it contains the aerosol-generating product. In other words, the heating tube and the containment cylinder 2 are two independent components.

[0012] Preferably, the heating tube is provided coaxially within the housing cylinder 2. The bottom end 32 of the heating tube has a vertical height higher than the bottom wall 22 of the housing cylinder 2.

[0013] Preferably, the housing cylinder 2 is shaped like a stepped tube and includes upper and lower parts with different diameters. The intersection of the upper and lower parts is a stepped section, and the diameter of the upper part is larger than the diameter of the lower part. The upper end of the lower part is fitted onto the heating tube 3, and the upper part surrounds the outside of the heating tube 3. In other words, there is no heating tube inside the lower part, but there is a heating tube inside the upper part. This ensures that the vertical height of the bottom end of the heating tube 3 in this invention is higher than the height of the bottom wall of the housing cylinder 2.

[0014] In addition, preferably, the heating tube is provided coaxially above the housing cylinder 2. Furthermore, the bottom end 32 of the heating tube is at a vertical height higher than the upper end of the housing cylinder 2. In other words, the heating tube and the housing cylinder 2 may partially overlap in the vertical direction, or they may be two completely separate sections.

[0015] Preferably, the heating unit 3 and the storage cylinder 2 are integrated, and the heating unit 3 is a part of the storage cylinder 2. That is, the portion of the storage cylinder 2 near the upper end has a heating function, and it serves as both a storage cylinder for containing the aerosol generating product and a heating unit for heating the aerosol generating product.

[0016] Preferably, a guide tube 4 for introducing an aerosol-generating product is provided in the ceiling opening 21 of the containment cylinder 2.

[0017] The bottom wall 22 of the containment cylinder 2 is capable of sealing at least a portion of one end face of the aerosol generating substrate of the contained aerosol generating product, so as to prevent or reduce the situation in which gas enters the aerosol generating substrate through one end face of the aerosol generating substrate. It should be noted that the ability of the bottom wall 22 to seal at least a portion of one end face of the aerosol generating substrate is optional. If a sealing member is provided on one end face of the aerosol generating substrate of the contained aerosol generating product, the configuration in which the bottom wall 22 seals at least a portion of that end face may be omitted or retained. However, if a sealing member is not provided on one end face of the aerosol generating substrate of the contained aerosol generating product, that is, if gas can enter the aerosol generating substrate through this end face without being blocked, then it is necessary to retain the configuration in which the bottom wall 22 seals at least a portion of that end face.

[0018] Preferably, the non-combustion, heated aerosol generating device is an electromagnetic heating device, with a coil 5 wound around the outer circumference of the heating section 3. The coil 5 is capable of generating electromagnetic induction. The heating section 3 is capable of generating heat by receiving electromagnetic induction generated by the coil 5. The heating section 3 is selected from, but is not limited to, electromagnetic metal materials. An insulating structure 6 is provided between the heating section 3 and the coil 5. Furthermore, the insulating structure 6 and the heating section 3 are provided with a gap between them.

[0019] In addition, preferably, the non-combustion, heated aerosol generating device is a resistance heating device. The heating section 3 is an insulating tube and has resistance heating wires on its inner surface and / or outer surface. Here, the insulating tube may be selected from a tube made of an insulating material such as ceramics, or a tube made of a non-insulating material that has been treated to provide insulation, such as metal. Furthermore, when resistance heating wires are present on the inner surface and / or outer surface, it is possible to form a resistance line by a method such as screen printing and heat the aerosol generating product using a resistance heating method. For the configuration of the heating tube in the present invention, refer to the description of the heating method of electromagnetic heating tubes and resistance heating method in the prior art.

[0020] In a second aspect, the present invention provides an aerosol generation system. This system includes the non-combustion / heating type aerosol generation apparatus and aerosol generation product 8 described in the first aspect of the present invention.

[0021] Preferably, the aerosol-generating product includes a tight section 81, an aerosol-generating substrate section 82, a gas pathway section 83, and a filter section 84.

[0022] The gas pathway section 83 is located between the aerosol-generating substrate section 82 and the filter section 84.

[0023] The tightly packed section 81 is located at one end of the aerosol-generating substrate section 82 that is separated from the filter section 84.

[0024] The gas path section 83 has an airflow path 831 that penetrates the gas path section 83 in the axial direction.

[0025] The axial air permeability of the tightly packed section 81 is less than the axial air permeability of the aerosol-generating substrate section 82. Preferably, the axial air permeability of the tightly packed section 81 is 0, that is, it does not allow the passage of gas in the axial direction.

[0026] The tight section 81, the aerosol generation substrate section 82, the gas path section 83 and the filter section 84 form each section of the aerosol generation product by being wound with a winding material, or form each section of the aerosol generation product by being packed and loaded into an integrally formed pipe.

[0027] Preferably, the bottom end of the heating part 3 has a vertical height higher than the connection point between the tight section 81 and the aerosol generation substrate section 82, or is aligned with the connection point.

[0028] Preferably, the tight section 81 is selected from non-aerosol generation materials including, but not limited to, carbon fiber materials, metal films, ceramics or polymer materials. The polymer materials are selected from, but not limited to, polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate or polylactic acid.

[0029] Alternatively, the materials of the tight section 81 and the aerosol generation substrate section 82 are the same, and both are selected from aerosol generation materials. The bulk density of the tight section 81 is greater than the bulk density of the aerosol generation substrate section 82. That is, in this case, the materials of the tight section 81 and the aerosol generation substrate section 82 are the same, and both are aerosol generation materials, but the tightness at both ends is completely different, and the density of the tight section 81 is greater than the density of the aerosol generation substrate section 82. Also, the axial air permeability of the tight section 81 is smaller than the axial air permeability of the aerosol generation substrate section 82. When the tight section 81 is an aerosol generation material, the tight section 81 can be integrally formed with the aerosol generation substrate section 82 in the manufacturing process of the aerosol generation substrate, and a high-density aerosol generation substrate section can be formed as the tight section 81 in the compression process, so the manufacturing is easy.

[0030] Preferably, the gas path section 83 is hollow and has a side wall and a hollow chamber. The hollow chamber is an air flow path 831 that penetrates the gas path section 83 in the axial direction. The gas path section 83 is cylindrical and made of acetate fiber material.

[0031] Preferably, the side wall of the gas path section 83 is further provided with side flow holes 832 that penetrate the side wall. The axial position of the side flow holes 832 is close to the position of the aerosol-generating substrate section 82 and spaced away from the position of the filter section 84. The reason for placing the side flow holes 832 even closer to the position of the aerosol-generating substrate section 82 is that the closer the axial position of the side flow holes 832 is to the aerosol-generating substrate section 82, the easier it is to extract aerosols from the aerosol-generating substrate section 82. The number of side flow holes 832 may be 6 to 8, but is not limited to this.

[0032] Preferably, the gas path section 83 includes a first gas path section 833 adjacent to the aerosol-generating substrate section 82 and a second gas path section 834 adjacent to the filter section 84. The first gas path section 833 and the second gas path section 834 may be a single unit or two separate sections.

[0033] The cross-sectional area of ​​the airflow path 831 in the first gas path section 833 is either less than or equal to the cross-sectional area of ​​the airflow path 831 in the second gas path section 834, or greater than the cross-sectional area of ​​the airflow path 831 in the second gas path section 834. If the gas path section 83 is hollow, it has side walls and a hollow chamber. The hollow chamber is an airflow path 831 that penetrates the gas path section 83 in the axial direction. The inner diameter of the hollow chamber body in the first gas path section 833 is either less than or equal to the inner diameter of the hollow chamber body in the second gas path section 834, or greater than the inner diameter of the hollow chamber body in the second gas path section 834. In this case, these connection points may be tapered slopes, vertical cross-sections, flat angles, or have an R-chamfered structure. If the inner diameter of the hollow chamber body in the first gas path section 833 is greater than the inner diameter of the hollow chamber body in the second gas path section 834, the amount of air drawn in by the first gas path section 833 will be greater. Therefore, the extraction effect on aerosols becomes better, and the amount of aerosols increases. On the other hand, if the inner diameter of the hollow chamber in the first gas pathway section 833 is smaller than the inner diameter of the hollow chamber in the second gas pathway section 834, the second gas pathway section 834 can collect more aerosols, and the condensation effect on aerosols becomes better. In addition, the cooling effect on aerosols becomes better, making them more suitable for inhalation.

[0034] Preferably, if the non-combustion, heated aerosol generating device is an electromagnetic heating device, the aerosol generating substrate section 82 is further provided with a metal tip 7 arranged axially. The central metal tip 7 can also sense the electromagnetic field generated by the coil and generate heat.

[0035] Preferably, the gas path section 83 is cylindrical and may be made from acetate fiber material or polymer material, but is not limited to these.

[0036] The aerosol-generating substrate section 82 contains an aerosol-generating material. The aerosol-generating material is in granular or filamentous form.

[0037] Here, we have merely illustrated and explained the forms of aerosol-generating materials; in reality, any aerosol-generating medium capable of generating aerosols is applicable, not limited to the forms mentioned above.

[0038] The total length of the aerosol generating product of the present invention may be 30 to 80 mm. Of this, the tightly packed section ranges from 2 to 10 mm, preferably 5 mm. The length of the aerosol generating substrate section 82 is 8 to 25 mm, preferably 12 mm. The length of the gas pathway section 83 is 10 to 20 mm, preferably 15 mm. The length of the filter section 84 is 8 to 15 mm, preferably 10 mm.

[0039] Assuming no contradictions arise, the above preferred solutions can be freely combined. [Effects of the Invention]

[0040] Compared to conventional technology, the present invention has the following beneficial effects.

[0041] 1. The non-combustion, heated aerosol generating apparatus of the present invention includes an apparatus body 1, a containment cylinder 2, and a heating section 3. The bottom end 32 of the heating section 3 is positioned such that its vertical height is higher than the height of the bottom wall 22 of the containment cylinder 2, so that the vertical height of the bottom end 32 of the heating section 3 is higher than the end face on one side of the aerosol generating substrate of the aerosol generating product. This ensures that the bottom end portion of the aerosol generating substrate of the aerosol generating product is not surrounded by the heating section. By keeping the temperature in this section low and virtually eliminating aerosol generation, the problem of uninhaled aerosols in this section condensing and flowing out from the end face after suction is stopped, thereby contaminating the bottom wall of the heating tube, is avoided.

[0042] 2. In a preferred embodiment of the present invention, the bottom wall 22 of the containment cylinder 2 is capable of sealing at least a portion of one end face of the aerosol generating substrate of the contained aerosol generating product, so as to prevent or reduce the situation in which gas enters the aerosol generating substrate through one end face of the aerosol generating substrate. This prevents the situation in which cold air enters the aerosol generating substrate section from the end face, causing the small amount of atomized aerosol in the aerosol generating substrate section to condense upon contact with the cold air, and the resulting liquid to flow out from the end face of the aerosol generating substrate section.

[0043] 3. The heating tube and the housing cylinder 2 in the present invention may be two independent components. The two components may be provided coaxially and partially overlap in the vertical direction, or they may be two completely separate sections. Alternatively, the heating tube and the housing cylinder 2 may be integrated, and the heating section 3 may be part of the housing cylinder 2. In this case, the portion of the housing cylinder 2 near the upper end has a heating function and serves as both a housing cylinder for containing the aerosol-generating product and a heating section for heating the aerosol-generating product. This structure is simpler and easier to implement.

[0044] 4. In a preferred embodiment of the present invention, the aerosol generating product 8 used is provided with a tightly sealed section 81 at one end of the aerosol generating substrate section 82 that is separated from the filter section 84. The axial air permeability of the tightly sealed section 81 is smaller than the axial air permeability of the aerosol generating substrate section 82. This reduces and prevents air from entering the aerosol generating substrate section 82 via the tightly sealed section 81. This prevents the situation in which cold air enters the aerosol generating substrate section from the end face, causing the small amount of atomized aerosol in the aerosol generating substrate section to condense upon contact with the cold air, and the resulting liquid to flow out from the end face of the aerosol generating substrate section.

[0045] 4. In conventional technology, gas passes through the end of the aerosol-generating substrate section during the inhalation process. As a result, the aerosol-generating substrate section becomes negatively pressurized during the inhalation process, and the problem arises that when inhalation stops, the aerosols that were not inhaled flow back from the filter section into the aerosol-generating substrate section.

[0046] However, by adding a tightly sealed section before the aerosol-generating substrate section, it becomes virtually impossible for outside air to pass through the tightly sealed section and replenish the aerosol-generating substrate section during the user's inhalation process, thus preventing the negative pressure in the aerosol-generating substrate section from rising. This prevents the aerosol from flowing back into the aerosol-generating substrate section and overflowing from the end face of the aerosol-generating substrate section when inhalation is stopped. Therefore, the problem of condensed aerosol overflowing from the end face of the aerosol-generating substrate section and contaminating the equipment is also resolved.

[0047] 5. In a preferred embodiment, the tightly packed section 81 is selected from a non-aerosol-generating material, but is not limited to carbon fiber material, metal film, ceramics, or polymer material. Alternatively, the tightly packed section 81 is selected from an aerosol-generating material. Furthermore, the density of the tightly packed section 81 is greater than the density of the aerosol-generating substrate section 82. Therefore, there is a wide range of material options. In addition, if the tightly packed section 81 is an aerosol-generating material, the tightly packed section 81 can be formed integrally with the aerosol-generating substrate section 82 during the manufacturing process of the aerosol-generating substrate, and a high-density aerosol-generating substrate section can be formed as the tightly packed section 81 during the compression process, making manufacturing easier.

[0048] 6. In a preferred embodiment, the side wall of the gas path section 83 is further provided with a side flow hole 832 that penetrates the side wall. By providing the side flow hole, inhalation of the aerosol is facilitated and the suction resistance during inhalation is reduced.

[0049] 7. In a preferred embodiment, the axial position of the side flow holes 832 is close to the position of the aerosol-generating substrate section 82 and spaced apart from the position of the filter section 84. The air drawn in through the side flow holes has an extractive effect on the aerosols generated in the aerosol-generating substrate section 82.

[0050] 8. In a preferred embodiment, the gas path section 83 includes a first gas path section 833 adjacent to the aerosol-generating substrate section 82 and a second gas path section 834 adjacent to the filter section 84. The cross-sectional area of ​​the airflow path 831 in the first gas path section 833 is less than or equal to the cross-sectional area of ​​the airflow path 831 in the second gas path section 834, or greater than the cross-sectional area of ​​the airflow path 831 in the second gas path section 834. If the gas path section 83 is hollow, it has side walls and a hollow chamber. The hollow chamber is an airflow path 831 that penetrates the gas path section 83 axially. The inner diameter of the hollow chamber body in the first gas path section 833 is less than or equal to the inner diameter of the hollow chamber body in the second gas path section 834, or greater than the inner diameter of the hollow chamber body in the second gas path section 834.

[0051] When the inner diameter of the hollow chamber in the first gas pathway section 833 is larger than the inner diameter of the hollow chamber in the second gas pathway section 834, the amount of air drawn into the first gas pathway section 833 increases. Therefore, the extraction effect on aerosols improves, and the amount of aerosols increases.

[0052] On the other hand, if the inner diameter of the hollow chamber in the first gas pathway section 833 is smaller than the inner diameter of the hollow chamber in the second gas pathway section 834, the second gas pathway section 834 can collect more aerosols, resulting in a better condensation effect on the aerosols. In addition, the cooling effect on the aerosols is improved, making them more suitable for inhalation. [Brief explanation of the drawing]

[0081] The aerosol generating product used in this embodiment is the same as in Example 1, but the non-combustion / heating type aerosol generating apparatus is different from that in Example 1.

[0082] In the non-combustion, heated aerosol generator used in this embodiment, the heating section 3 is a heating tube provided separately from the containment cylinder 2, and together with the containment cylinder 2, it contains the aerosol-generating product. The heating tube is provided coaxially above the containment cylinder 2. Furthermore, the bottom end 32 of the heating tube 3 has a vertical height higher than the top end of the containment cylinder 2. Other features of the non-combustion, heated aerosol generator are the same as in Embodiment 1. [Examples]

[0083] The aerosol generating product used in this embodiment is the same as in Example 1, but the non-combustion / heating type aerosol generating apparatus is different from that in Example 1.

[0084] In the non-combustion, heated aerosol generator used in this embodiment, the heating unit 3 and the containment cylinder 2 are integrated, with the heating unit 3 being a part of the containment cylinder 2. That is, the portion of the containment cylinder 2 near the upper end has a heating function, and thus serves as both a containment cylinder for containing the aerosol-generating product and a heating unit for heating the aerosol-generating product. Other features of the non-combustion, heated aerosol generator are the same as in Embodiment 1. [Examples]

[0085] As shown in Figure 3, the non-combustion, heated aerosol generator used in this embodiment is the same as in Example 1. However, the aerosol product produced is different.

[0086] The structure of the aerosol-generating product 8 having a tightly packed section shown in Figure 4 differs from that of Example 1 in the following respects. Specifically, the aerosol-generating substrate section 82 is further equipped with a metal chip 7 provided in the axial direction. The central metal chip 7 can also sense the electromagnetic field generated by the coil and generate heat. [Examples]

[0087] The non-combustion, heated aerosol generator used in this embodiment is the same as in Example 1. However, the aerosol product produced is different.

[0088] As shown in Figure 5, the structure of the aerosol-generating product 8 having a tightly packed section differs from that of Example 1 in the following respects. Specifically, the gas pathway section 83 includes a first gas pathway section 833 adjacent to the aerosol-generating substrate section 82 and a second gas pathway section 834 adjacent to the filter section 84. The first gas pathway section 833 and the second gas pathway section 834 are two separable sections.

[0089] The cross-sectional area of ​​the airflow path 831 in the first gas path section 833 is smaller than the cross-sectional area of ​​the airflow path 831 in the second gas path section 834. If the gas path section 83 is hollow, it has side walls and a hollow chamber. The hollow chamber is an airflow path 831 that penetrates the gas path section 83 in the axial direction. The inner diameter of the hollow chamber body in the first gas path section 833 is smaller than the inner diameter of the hollow chamber body in the second gas path section 834. In this case, the connection point may be a tapered slope.

[0090] When the inner diameter of the hollow chamber in the first gas pathway section 833 is smaller than the inner diameter of the hollow chamber in the second gas pathway section 834, the second gas pathway section 834 can collect more aerosols, resulting in a better condensation effect on the aerosols. In addition, the cooling effect on the aerosols is improved, making it more suitable for inhalation. [Examples]

[0091] The non-combustion, heated aerosol generator used in this embodiment is the same as in Example 1. However, the aerosol product produced is different.

[0092] As shown in Figure 6, the structure of the aerosol-generating product 8 having a tightly packed section differs from that of Example 1 in the following respects. Specifically, the gas pathway section 83 includes a first gas pathway section 833 adjacent to the aerosol-generating substrate section 82 and a second gas pathway section 834 adjacent to the filter section 84. The first gas pathway section 833 and the second gas pathway section 834 are two separable sections.

[0093] The cross-sectional area of ​​the airflow path 831 in the first gas path section 833 is larger than the cross-sectional area of ​​the airflow path 831 in the second gas path section 834. If the gas path section 83 is hollow, it has side walls and a hollow chamber. The hollow chamber is an airflow path 831 that penetrates the gas path section 83 in the axial direction. The inner diameter of the hollow chamber body in the first gas path section 833 is larger than the inner diameter of the hollow chamber body in the second gas path section 834. In this case, the connection points may be tapered slopes.

[0094] When the inner diameter of the hollow chamber in the first gas pathway section 833 is larger than the inner diameter of the hollow chamber in the second gas pathway section 834, the amount of air drawn into the first gas pathway section 833 increases. Therefore, the extraction effect on aerosols improves, and the amount of aerosols increases. [Examples]

[0095] The non-combustion, heated aerosol generator used in this embodiment is the same as in Example 1. However, the aerosol product produced is different.

[0096] As shown in Figure 7, the structure of the aerosol-generating product 8 having a tightly packed section differs from that of Example 1 in the following respects. Specifically, the tightly packed section 81 is selected from the aerosol-generating material. Furthermore, the density of the tightly packed section 81 is greater than the density of the aerosol-generating substrate section 82. In other words, in this case, the material of the tightly packed section 81 and the material of the aerosol-generating substrate section 82 are the same, and both are aerosol-generating materials, but the tightness densities at both ends are completely different, with the density of the tightly packed section 81 being greater than the density of the aerosol-generating substrate section 82. Also, the axial air permeability of the tightly packed section 81 is less than the axial air permeability of the aerosol-generating substrate section 82.

[0097] The tightly packed section 81 is formed integrally with the aerosol-generating substrate section 82 during the manufacturing process of the aerosol-generating substrate, and since a high-density aerosol-generating substrate section can be formed as the tightly packed section 81 during the compression process, manufacturing is easy.
