Aerosol-generating media and aerosol-generating products

Abstract

An embodiment of the present invention provides an aerosol-generating medium and an aerosol-generating product, the aerosol-generating medium comprising an aerosol matrix and a heating element, the aerosol matrix having a passage penetrating at least one end along the longitudinal direction of the aerosol matrix, the heating element being provided in the aerosol matrix and used to heat the aerosol matrix. In the aerosol-generating medium according to the embodiment of the present invention, since the heating element is provided in the aerosol matrix, after the aerosol-generating product is inserted into the heating chamber, the aerosol generating device does not need to be configured to insert the aerosol matrix; instead, the power output unit simply transmits electrical energy to the heating element. In this way, when the aerosol-generating medium is completely heated and the aerosol generating device is separated, the heated solid powder or granules of the aerosol matrix are less likely to fall into the heating chamber, thereby less likely to contaminate the heating chamber and reducing the amount of cleaning required by the user.

Description

[Technical Field]

[0001] [Cross-Citation of Related Applications] The present invention is based on and claims priority from a Chinese patent application having application number 202310140309.X and filing date February 20, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to the technical field of smoke-producing products, and in particular to aerosol-generating media and aerosol-generating products. [Background technology]

[0003] Smoke-generating products include those that form aerosols upon ignition and those that form aerosols by heating but not combustion. However, a typical heat-but-not-combustion smoking product includes an aerosol-forming matrix, such as tobacco material, flavor material, and / or atomizing agent, that volatilizes upon heating to form an aerosol. The aerosol-forming matrix is ​​heated by an external heat source to a temperature sufficient for release, and the aerosol-forming matrix carries the atomizing agent without combustion. During use, the atomizing agent is released by high-temperature heating to form smoke.

[0004] In some related technologies, a heating element is installed in the heating chamber of the aerosol generating device, and when inhalation is required, the smoke-producing product is inserted into the heating chamber of the aerosol generating device, and at the same time, the heating element in the heating chamber is inserted into the smoke-producing product, heating the smoke-producing product from the inside to the outside. After the smoke-producing product has been heated, when it is separated from the heating element, the two move relative to each other, making it easy for solid powders such as residues adhering to the heating element to fall into the aerosol generating device. This requires the user to regularly clean the heating chamber, which not only increases the user's workload but also poses a risk of damaging the heating element if the cleaning is not done properly. Summary of the Invention

[0027] The embodiments of the present invention will be described in more detail below with reference to the drawings and examples. The following examples are intended to illustrate the present invention but cannot limit the scope of the present invention.

[0028] In describing embodiments of the present invention, the terms "first," "second," and "third" are used solely to describe purpose and should not be understood as indicating or implying their relative importance.

[0029] An embodiment of the present invention provides an aerosol-generating medium 10, which comprises an aerosol matrix 11 and a heating element 12, as shown in Figures 4, 5, 7, 9, 14, 17, 18, 20, 21, 25, 29, and 26.

[0030] The aerosol matrix 11, when heated, generates an aerosol that is inhaled by a user. In an embodiment of the present invention, the aerosol-generating medium 10 has a generally cylindrical shape. However, the cylindrical shape may be, but is not limited to, a circular cylinder (i.e., having a circular cross-section), a prismatic cylinder (i.e., having a polygonal cross-section), an elliptical cylinder (i.e., having an elliptical cross-section), or the like.

[0031] The aerosol matrix 11 has a passageway that penetrates at least one end along the longitudinal direction of the aerosol matrix 11. That is, the passageway extends along the length of the aerosol matrix 11.

[0032] In some embodiments, the passages extend through the same longitudinal end of the aerosol matrix 11, as shown in FIG.

[0033] In some other embodiments, as shown in FIG. 31, some of the passages penetrate one longitudinal end of the aerosol matrix 11 and some of the passages penetrate the other longitudinal end of the aerosol matrix 11.

[0034] In some embodiments, as shown in Figures 7, 9, 14, 20-22, 25, and 29, each passage penetrates both ends of the aerosol matrix 11 along the longitudinal direction, and airflow can flow from one end of the aerosol matrix 11 along the longitudinal direction through the air passage hole 10a to the other end of the aerosol matrix 11 along the longitudinal direction.

[0035] In an embodiment of the present invention, the longitudinal direction of the aerosol matrix 11 and the longitudinal direction of the aerosol-generating medium 10 are the same.

[0036] For example, the aerosol matrix 11 is a particle conjugate, such as a recombinant tobacco vehicle containing components such as a smoking agent and tobacco. The aerosol matrix 11 is an integrated structure that can be manufactured, for example, by injection, compression, or extrusion processes. Extrusion is a processing method in which a raw material mixture is introduced into an extruder, where it is thermally plasticized by the action between the barrel and screw of the extruder, and the screw extrudes the material forward, continuously passing through a die at the extrusion port of the extruder to produce various cross-sectional products or semi-finished products. The aerosol matrix formed by extrusion has a striped shape.

[0037] Because the aerosol matrix 11 is a particle aggregate, after the aerosol matrix 11 is sucked in by heat or after heating is stopped, it remains a monolithic medium and is unlikely to collapse and fall. This solves the problems of sheets coming off, thread-like or particle components falling off, difficulty in cleaning, and uneven components that occurred in prior art aerosol-generating matrices that are sheet-like, thread-like, or scattered particles.

[0038] Micropores are formed between the particles of the particle aggregate, that is, the gaps between the particles constitute the micropores, and the micropores communicate with each other and form micro-air passages that communicate with the passage.

[0039] The micro-channels can increase the surface area of ​​the aerosol matrix 11, facilitating the transfer of heat from the surface of the micro-channels to the interior of the medium, improving heating efficiency. The medium in the aerosol matrix 11 receives heat and releases aerosol, which is collected in the passages through the micro-channels and transported to the suction end by suction negative pressure. The passages reduce the suction resistance of the user, improving the user experience.

[0040] The heating element 12 is provided in the aerosol matrix 11 and is used to heat the aerosol matrix 11. In other words, the heating element 12 is integrally formed with the aerosol matrix 11.

[0041] An embodiment of the present invention further provides an aerosol-generating product 100, as shown in Figures 3, 4 and 5, comprising a functional segment 30, an outer coating layer 20 and an aerosol-generating medium 10 according to any embodiment of the present invention.

[0042] The aerosol-generating product 100 relies on the aerosol matrix 11 to generate the aerosol, and the functional segment 30 does not generate the aerosol.

[0043] The aerosol-generating product 100 according to the embodiment of the present invention may be applied to a method of heating and burning, and then inhaled, or may be applied to a method of heating but not burning, and then inhaled.

[0044] In the embodiment of the present invention, the aerosol-generating product 10 is described as being applied to inhalation in a manner that heats but does not burn. The functional segment 30 is provided at one end along the longitudinal direction of the aerosol-generating medium 10. The functional segment 30 includes at least a filtration segment 31 for filtering the aerosol. The filtration segment 31 is also called a filter. A user inhales the filtered aerosol through the filtration segment 31 of the functional segment 30.

[0045] The aerosol-generating product 100 is intended for use in conjunction with an aerosol-generating device 200 .

[0046] For example, as shown in Figures 1 and 2, the aerosol generating device 200 comprises a housing 201 and a power supply unit arranged within the housing 201, the housing 201 having a heating chamber 200a, the power supply unit having a power output section, when a portion corresponding to a certain length range of the aerosol matrix 11 of the aerosol generating product 100 is inserted into the heating chamber 200a, the power output section transmits electrical energy to the heating element 12 in a contact or non-contact manner, the heating element 12 generates heat upon receiving electrical energy from the outside, and heats and atomizes the aerosol matrix 11, thereby generating aerosol.

[0047] In the aerosol-generating medium 10 according to the embodiment of the present invention, the heating element 12 is provided in the aerosol matrix 11. Therefore, after the aerosol-generating product 100 is inserted into the heating chamber 200a, the aerosol-generating device 200 does not have any components or parts to be inserted into the aerosol matrix 11; the power output unit simply transmits electrical energy to the heating element 12. In this way, when the aerosol-generating medium 10 is separated from the aerosol-generating device 200 after heating, solid or semi-solid powder or granules in the aerosol matrix 11 after heating are unlikely to fall into the heating chamber 200a and contaminate the heating chamber 200a, reducing the amount of cleaning work required by the user.

[0048] In the embodiment of the present invention, the longitudinal direction does not particularly refer to the direction in which the external outline of the aerosol-generating medium 10 is longest. Specifically, the arrangement direction of the functional segments 30 and the aerosol-generating medium 10 coincides with the longitudinal direction, and the direction in which the aerosol-generating product 100 is inserted into the heating chamber 200a and the direction in which the aerosol-generating product 100 is removed from the heating chamber 200a are both parallel to the longitudinal direction. The length of the aerosol-generating medium 10 along the longitudinal direction may be longer, shorter, or the same as the lengths in other directions.

[0049] For example, if the aerosol-generating medium 10 has a cylindrical outer contour, the longitudinal direction is the axial direction of the aerosol-generating medium 10. Note that even if the axial length of the aerosol-generating medium 10 is shorter than the diameter, the longitudinal direction of the aerosol-generating medium 10 is still the axial direction. Furthermore, if the aerosol-generating medium 10 has a rectangular parallelepiped outer contour, the longitudinal direction is still the direction defined above, i.e., the direction in which the functional segments 30 and the aerosol-generating medium 10 are arranged, or the direction in which the aerosol-generating product 100 is introduced into and removed from the heating chamber 200a. The longitudinal direction of the aerosol-generating medium 10 may be any of the length, width, and height directions of the rectangular parallelepiped.

[0050] When the aerosol-generating medium 10 is used alone, i.e., when not combined with the functional segment 30, the longitudinal direction is the perpendicular direction of the distance between both ends of the aerosol-generating medium 10. For example, if the aerosol-generating medium 10 is cylindrical, the longitudinal direction is the perpendicular direction of the distance between both end faces. For example, if the aerosol-generating medium 10 is cylindrical with a cross section having a triangular, polygonal, oval, or elliptical shape, the longitudinal direction is the axial direction. If the aerosol-generating medium 10 is rectangular, the longitudinal direction of the aerosol-generating medium 10 may be any one of the length, width, or height directions of the rectangular parallelepiped.

[0051] In some embodiments, the heating element 12 is connected to the aerosol matrix 11 in direct contact with the aerosol matrix 11, which facilitates the heating element 12 to directly transfer heat to the aerosol matrix 11, improving the heat transfer efficiency. In other embodiments, the heating element 12 is not in direct contact with the aerosol matrix 11, but a heat transfer member is provided between the heating element 12 and the aerosol matrix 11, and the heat generated by the heating element 12 is transferred to the aerosol matrix 11 via the heat transfer member, and the heating element 12 and the aerosol matrix 11 are connected by the heat transfer member.

[0052] The outer coating layer 20 is coated on the outer circumferential surface of the functional segment 30 and the aerosol-generating medium 10 .

[0053] The outer coating layer 20 may include, but is not limited to, one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE, PBAT, etc.

[0054] In some embodiments, functional segment 30 comprises only filtration segment 31. In other embodiments, functional segment 30 further comprises, in addition to filtration segment 31, a support segment and / or a cooling segment 32 disposed between aerosol matrix 11 and filtration segment 31.

[0055] However, the temperature-lowering segment 32 performs a temperature-lowering process on the aerosol before the filtering segment 31 filters the aerosol, thereby lowering the temperature of the aerosol and improving the phenomenon of "burning the mouth" when the user inhales the aerosol.

[0056] Materials for the temperature-lowering segment 32 include, but are not limited to, one or a combination of two or more of PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, and acrylic fiber materials.

[0057] The material of the filtration segment 31 includes, but is not limited to, one or a combination of two or more of PE (polyethylene), PLA (Polylactic acid, also called polylactide), PBAT (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, and acrylic fiber material.

[0058] The materials of the temperature-reducing segment 32 and the filtration segment 31 may be the same or different.

[0059] The support segments have a certain degree of strength and act as axial limits for the aerosol-generating medium 10. Specifically, when the aerosol-generating product 100 is inserted into the heating chamber 200a in the aerosol-generating device 200, the support segments provide a reaction force to the aerosol-generating medium 10, preventing the aerosol-generating medium 10 from moving along the axial direction.

[0060] The specific components of the aerosol matrix 11 are not limited herein, but for example, in one embodiment, the aerosol matrix 11 may include a botanical component, an auxiliary component, a smoke generating component, a binder component, and the like.

[0061] In one embodiment, the botanical ingredients are one or a combination of tobacco leaf material, tobacco leaf fragments, tobacco stems, tobacco powder, and powders obtained by crushing aromatic plants, etc. The botanical ingredients are used to generate an aerosol, such as nicotine, when heated.

[0062] In one embodiment, the auxiliary component may be one or a combination of inorganic fillers, lubricants, and emulsifiers. Examples of inorganic fillers include ground calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic fillers can provide skeletal support for the plant components. At the same time, the inorganic fillers have micropores, which can improve the porosity of the wall material after the plant components are molded, thereby improving the aerosol release rate.

[0063] Lubricants include one or more of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. Lubricants can improve particle flow, reduce friction between particles, make the density of the entire particle distribution uniform, reduce the pressure required for molding, and reduce mold wear.

[0064] The emulsifier may be one or a combination of polyglycerol fatty acid ester, Twain-80, and polyvinyl alcohol. The emulsifier can partially mitigate the loss of flavoring substances during storage, increase the stability of flavoring substances, and improve the sensory quality of the product.

[0065] The smoke generating agent component generates a large amount of vapor upon heating, thereby enhancing the aerosol volume of the aerosol matrix. In one embodiment, the smoke generating agent can be one or more of the following: a monohydric alcohol (e.g., menthol), a polyol (e.g., propylene glycol, triethylene glycol, 1,3-butanediol and glycerin), an ester of a polyol (e.g., glycerol monoacetate, glycerol diacetate, or glycerol triacetate), a monocarboxylic acid, a polycarboxylic acid (e.g., lauric acid, myristic acid), or an aliphatic ester of a polycarboxylic acid (e.g., dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, mesoerythritol, diethyl glycerol diacetate, triethyl citrate, phenylmethyl phenyl benzoate, ethyl vanilla, glycerol tributyrate, and lauryl acetate).

[0066] In one embodiment, the adhesive is a natural plant extract and a non-ionized modified viscous polysaccharide, such as one or more of tamarind polysaccharide, proline polysaccharide, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive is used to bond particles together to prevent loosening, improve the water resistance of the aerosol-generating matrix, and is harmless to the human body and beneficial to some extent to human health.

[0067] It should be noted that the above-mentioned passages are macropores and micropores are micropores, and the cross-sectional area of ​​the passages is much larger than the cross-sectional area of ​​the micropores, although the size of the micropores is determined by the gaps between the particles.

[0068] For example, the cross-sectional area of ​​the passage is at least 20 times the cross-sectional area of ​​the micropore. If the size of the micropore remains almost the same, if it is less than 20 times, the size of the passage will be too small, making it difficult for the aerosol to be released from the inner wall of the passage into the passage, increasing the user's inhalation resistance and reducing the user's inhalation experience. Therefore, in this embodiment, if the cross-sectional area of ​​the passage is 20 times or more than the cross-sectional area of ​​the micropore, the aerosol can be released quickly from the inner wall of the passage, reducing the inhalation resistance and improving the user's inhalation experience.

[0069] In some embodiments, the cross-sectional area of ​​the passage is 20 to 60,000 times that of the pores. If the cross-sectional area of ​​the passage is more than 60,000 times that of the pores, the area of ​​the passage is too large, which reduces the overall quality of the smoke generating medium, reduces medium utilization, increases the heating rate, and makes it easier for aerosols to be released into the environment through the pores.

[0070] For example, the cross-sectional area of ​​the passage is 100 to 40,000 times larger than the cross-sectional area of ​​the pore.

[0071] The specific configuration of the heating element 12 is not limited.

[0072] For example, in some embodiments, the heating element 12 includes at least an electromagnetic induction unit for inducing changes in an external magnetic field to generate heat. In this embodiment, the power output unit includes an inductance coil. When an alternating current flows through the inductance coil, an alternating magnetic field is generated. The electromagnetic induction unit is positioned within the alternating magnetic field and cuts the alternating magnetic field lines, generating eddy currents in the electromagnetic induction unit. The eddy currents cause carriers in the electromagnetic induction unit to move randomly at high speed, generating thermal energy through collisions and friction between the carriers and atoms. This causes the heating element 12 to generate heat and heat the aerosol matrix 11. In this embodiment, electrical energy is transmitted between the power output unit and the heating element 12 without contact.

[0073] There are no specific limitations on the material of the electromagnetic induction portion, but it may be, for example, metal, conductive ceramics, or other materials.

[0074] The arrangement of the inductance coil is not limited, and may be arranged on the circumferential sidewall of the heating chamber 200a or on the bottom wall of the heating chamber 200a, and is not limited here.

[0075] In the above embodiments, the configuration of the heating element 12 is not limited, but for example, in some embodiments, the entire heating element 12 is made of a metal material or conductive ceramics, i.e., the entire heating element 12 is an electromagnetic induction part. In other embodiments, the heating element 12 includes an insulating substrate and the above-mentioned electromagnetic induction part, and the electromagnetic induction part may be provided in the form of a layer on the surface of the insulating substrate.

[0076] In some other embodiments, the heating element 12 includes a conductive heating portion and a contact portion electrically connected to the conductive heating portion, and the contact portion is used to energize the conductive heating portion to generate heat by contacting an external power terminal. In this embodiment, the power output portion includes two terminals, a positive power terminal and a negative power terminal, and the contact portion includes a positive contact and a negative contact. When the aerosol-generating product 100 is inserted into the heating chamber 200a, the positive contact contacts the positive power terminal and the negative contact contacts the negative power terminal. In this way, when an electric circuit is connected to the conductive heating portion and current is applied to the positive power terminal and the negative power terminal, current is applied to the conductive heating portion to realize heating by electrical resistance, and further heat the aerosol matrix 11. In this embodiment, electrical energy is transmitted between the power output portion and the heating element 12 so that they are in contact with each other. There are no specific limitations on the material of the conductive heating portion, but it may be, for example, metal, conductive ceramics, or other materials.

[0077] In the above embodiments, the configuration of the heating element 12 is not limited, but for example, in some embodiments, the entire heating element 12 is made of a metal material or a conductive ceramic. In other embodiments, the heating element 12 further includes an insulating base, and the electric heating portion is provided on the insulating base.

[0078] The number of the heating element 12 may be one or more. In the embodiment of the present invention, an example in which the number of the heating element 12 is one will be described.

[0079] Illustratively, the number of heating elements 12 is one, and the heating element 12 extends along the longitudinal direction of the aerosol matrix 11. That is, the dimension of the heating element 12 in the longitudinal direction of the aerosol matrix 11 is much larger than the dimension perpendicular to the longitudinal direction of the aerosol matrix 11.

[0080] The manufacturing process for combining the heating element 12 and the aerosol matrix 11 is not limited.

[0081] For example, the heating element 12 can be embedded in the aerosol matrix 11 after the aerosol matrix 11 is molded. Alternatively, the heating element 12 and the aerosol matrix 11 can be directly molded integrally by a process such as die-casting. Specifically, the heating element 12 is placed in a mold, a mixture for preparing the aerosol matrix 11 is contained in the mold, and the mold is then closed to perform die-casting. After the mold is opened, the heating element 12 and the aerosol matrix 11 are combined into an integral structure.

[0082] In some embodiments, as shown in FIGS. 3, 6, 10, 11, 12, and 15-27, aerosol matrix 11 includes prefabricated holes 10c that extend through at least one longitudinal end of aerosol matrix 11, and heating elements 12 are disposed within prefabricated holes 10c. In these embodiments, heating elements 12 are fitted into aerosol matrix 11 after aerosol matrix 11 is molded. Specifically, when preparing aerosol matrix 11, prefabricated holes 10c are formed, and after aerosol matrix 11 is molded, heating elements 12 are inserted into prefabricated holes 10c. In these embodiments, because prefabricated holes 10c are provided, inserting heating elements 12 into prefabricated holes 10c places little or no pressure on the surrounding structure around prefabricated holes 10c when heating elements 12 are inserted into prefabricated holes 10c, thereby ensuring a relatively uniform density of aerosol matrix 11.

[0083] In some other embodiments, the heating element 12 can be inserted directly into the aerosol matrix 11 after the aerosol matrix 11 is formed without prefabricated holes 10c in the aerosol matrix 11 in advance.

[0084] The arrangement of the heating element 12 in a plane perpendicular to the longitudinal direction of the aerosol matrix 11 is not limited.

[0085] Illustratively, the heating element 12 is disposed on the central axis of the aerosol matrix 11. However, the central axis is a virtual reference line, and in a plane perpendicular to the longitudinal direction of the aerosol matrix 11, the central axis is located at the center of the cross section of the aerosol matrix 11. In this embodiment, the heat generated by the heating element 12 is distributed radially, and heat is received uniformly all around the heating element 12, stabilizing the aerosol matrix 11 and uniformly discharging the aerosol.

[0086] In some other embodiments, the heating element 12 may be located off-center relative to the central axis, i.e., the heating element 12 may not be located at the central axis.

[0087] The specific shape of the heating element 12 is not limited.

[0088] Illustratively, the heating element 12 has a sheet shape and extends along the longitudinal direction of the aerosol matrix 11 .

[0089] However, the shape of the cross section of the sheet-like heat generating element 12 is not limited, and may be, for example, V-shaped, linear, or arc-shaped.

[0090] In some other embodiments, the heating element 12 is columnar and extends along the length of the aerosol matrix 11 .

[0091] However, the shape of the cross section of the columnar heating element 12 is not limited, and may be, for example, a circle, an ellipse, a polygon, or the like.

[0092] In some embodiments, a portion of heating element 12 is exposed to the outer surface of aerosol matrix 11, e.g., one or both ends are flush with or protrude from the end surface of aerosol matrix 11. In other embodiments, aerosol matrix 11 completely covers the exterior of heating element 12, i.e., no portion of heating element 12 is exposed to the outer surface of aerosol matrix 11. In this manner, the contact area between heating element 12 and aerosol matrix 11 is large, improving heating efficiency.

[0093] For example, as shown in Figure 22, a blind passage 10d is provided inside the aerosol matrix 11, and at least one end of the blind passage 10d along the longitudinal direction is closed. In some embodiments, only one end of the blind passage 10d is closed, while the other end forms an opening on the outer surface of the aerosol matrix 11. In other embodiments, as shown in Figure 22, both ends of the blind passage 10d are closed. During the preparation process, a portion of the aerosol matrix 11 is prepared first, and after the blind passage 10d is formed, the remaining portion of the aerosol matrix 11 is prepared again. In this manner, a blind passage 10d with both ends closed can be formed.

[0094] In this embodiment, during the process of the user intermittently inhaling, the blind passage 10d can increase the internal temperature of the aerosol matrix 11 when the user is not inhaling, thereby reducing the output of the aerosol generating device 200, lengthening the duration of a single flight of the aerosol generating device 200, and also improving the overall heating uniformity of the aerosol matrix 11 and the consistency of aerosol release.

[0095] The number of passages is not limited, and may be one or more.

[0096] For example, in some embodiments, the passages include air duct holes 10a provided inside the aerosol-generating medium 10. That is, at least some of the passages are air duct holes 10a. In a cross section perpendicular to the longitudinal direction of the aerosol-generating medium 10, the head and tail of the hole walls of the air duct holes 10a are connected to form a single closed hole. The air duct holes 10a help to improve the uniformity of heat reception by the internal medium.

[0097] 8, 11, 12, and 20, the passages have air channel grooves 10b provided on the circumferential surface of the aerosol matrix 11. In other words, some areas of the outer wall of the aerosol matrix 11 are recessed to form the air channel grooves 10b, and the recessed air channel grooves 10b are visible from the outer wall of the aerosol matrix 11.

[0098] In addition, the outer coating layer 20 can close the air channel grooves 10b on the outer wall of the aerosol-generating medium 10, and the air channel grooves 10b can also serve as air flow passages for the aerosol, thereby increasing the amount of air intake and the efficiency of aerosol extraction.

[0099] In some embodiments, all of the passages are airway grooves 10b, ie, in such embodiments, there are no airway holes 10a.

[0100] In some other embodiments, as shown in Figures 6, 8, 10, 13, 15 to 20, and 24 to 28, all passages are air duct holes 10a, that is, in these embodiments, there are no air duct grooves 10b.

[0101] In some embodiments, as shown in Figures 8, 11, 12, and 23, some of all the passages are air duct grooves 10b and some are air duct holes 10a, i.e., in such embodiments, both air duct holes 10a and air duct grooves 10b are present.

[0102] The shape of the air duct hole 10a is not limited, but for example, in a plane perpendicular to the longitudinal direction of the aerosol generating medium 10, the cross-sectional shape of the air duct hole 10a includes at least one of a circle, an ellipse, a track shape, a polygon, and a sector shape.

[0103] However, the track shape is similar to a running track, with two semicircles and two parallel straight sides connected alternately.

[0104] When there are multiple air duct holes 10a, the cross-sectional shapes of the air duct holes 10a may be exactly the same, or there may be both air duct holes 10a with the same cross-sectional shape and air duct holes 10a with different cross-sectional shapes. For example, in some embodiments, the cross-sectional shapes of all the air duct holes 10a may be circular, elliptical, triangular, rectangular, etc., and in other embodiments, there may be air duct holes 10a with triangular cross-sectional shapes and air duct holes 10a with circular, etc., cross-sectional shapes.

[0105] For example, if there are multiple air duct holes 10a, each air duct hole 10a has the same shape and dimensions. For example, all air duct holes 10a are equilateral triangles, and the sides of all equilateral triangles have the same length. Also, for example, all air duct holes 10a are circles with the same radius. In this way, each air duct hole 10a of the aerosol matrix 11 is molded using the same mold, which reduces manufacturing costs.

[0106] In an embodiment in which there are a plurality of air duct holes 10a, the arrangement of the air duct holes 10a is not limited.

[0107] For example, all the air passage holes 10a may be arranged in a matrix, a circular ring, a square, or a cross.

[0108] In the embodiments of the present invention, the configurations shown in the drawings do not limit the relative size relationship between the air duct holes 10a and the aerosol matrix 11. The air duct holes 10a in the drawings are merely intended to more clearly show the arrangement relationship of the air duct holes 10a, and do not specify their specific dimensions.

[0109] For example, the cross-sectional area of ​​the air passage hole 10a is 0.0019 mm 2 ~30mm 2 (square millimeters). For example, 0.002 mm 2 , 0.1 mm 2 , 0.2mm 2 , 0.4mm 2 , 0.5mm 2 , 0.8mm 2 , 1mm 2 , 1.3mm 2 , 1.6mm 2 , 1.8mm 2 , 2mm 2 , 2.1mm 2 , 2.2mm 2 , 2.4mm 2 , 2.6mm 2 , 2.8mm 2 , 3mm 2 , 4mm 2 , 5mm 2 , 6mm 2 And so on.

[0110] The cross-sectional area of ​​the air passage hole 10a is 30 mm 2 If it is larger, the number of air duct holes 10a will be small, and the aerosol matrix 11 will be prone to burning, and uneven aerosol emission will occur during heating of the aerosol matrix 11 (for example, the first two sips will emit a large amount of aerosol, while the last few sips will emit a small amount of aerosol), which will affect the user's inhalation experience.

[0111] The cross-sectional area of ​​the air passage hole 10a is 0.0019 mm 2 If it is smaller, the molding process becomes significantly more difficult, the size of the air passage holes 10a becomes hard to control, and the rate of defective aerosol matrices 11 increases.

[0112] The cross-sectional area of ​​the air passage hole 10a is 0.0019 mm 2 ~30mm 2 Within this range, the flow resistance of the aerosol matrix 11 is relatively small (i.e., the suction resistance is relatively small), the aerosol flow rate is appropriate, the aerosol inside the aerosol matrix 11 is easy to extract, the aerosol is released uniformly and has a high utilization rate, the aerosol matrix 11 is less likely to burn, the user's experience is relatively good, and it is easy to process and manufacture.

[0113] In some embodiments, the cross-sectional area of ​​the air passage hole 10a is 0.007 mm 2 ~7.1mm 2 (square millimeters). For example, 0.1 mm 2 , 0.2mm 2 , 0.4mm 2 , 0.5mm 2 , 0.8mm 2 , 1mm 2 , 1.3mm 2 , 1.6mm 2 , 1.8mm 2 , 2mm 2 , 2.1mm 2 , 2.2mm 2 , 2.4mm 2 , 2.6mm 2 , 2.8mm 2 , 3mm 2 And so on.

[0114] In a cross section perpendicular to the longitudinal direction of the aerosol matrix 11, all of the air passage holes 10a may be distributed uniformly or unevenly.

[0115] For example, the hydraulic diameter of the air duct hole 10a is 0.1 mm to 3 mm (millimeters), such as 0.1 mm, 0.2 mm, 0.4 mm, 0.5 mm, 0.8 mm, 1 mm, 1.3 mm, 1.6 mm, 1.8 mm, 2 mm, 2.1 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3 mm, etc.

[0116] In the present embodiment, hydraulic diameter means the ratio of four times the cross-sectional area of ​​the vortex to the circumference.

[0117] For example, the cross-sectional area of ​​the micropores is 0.7 nm 2 (square nanometer) ~ 710μm 2 (square micrometer). For example, 1 nm 2 , 10nm 2 , 25nm 2 , 30nm 2 , 40nm 2 , 50nm 2 , 60nm 2 , 70nm 2 , 80nm 2 , 100 nm 2 , 200 nm 2 , 300 nm 2 , 400nm 2 , 500nm 2 , 600nm 2 , 700nm 2 , 800nm 2 , 900nm 2 , 1 μm 2 , 2 μm 2 , 3 μm 2 And so on.

[0118] The cross-sectional area of ​​the micropores is 0.7 nm 2 If the cross-sectional area of ​​the micropores is smaller than 710 μm, the active ingredients inside the media will volatilize and will have difficulty entering the passages, resulting in a decrease in the utilization rate of the media. 2 If the cross-sectional area of ​​the micropores is larger than this, the heat conduction within the micropores becomes uneven, and the suction experience deteriorates. 2 ~710μm 2 This allows for both improved utilization of the medium and improved suction experience. 2 ~20μm 2 It is more preferable that:

[0119] The cross-sectional area of ​​the micropores is 1963 nm 2 ~20μm 2 It is desirable that

[0120] Exemplarily, the hydraulic diameter of the pores is 10 nm (nanometers) to 30 μm (micrometers), such as 10 nm, 20 nm, 24 nm, 30 nm, 40 nm, 50 nm, 60 nm, 70 nm, 80 nm, 100 nm, 200 nm, 300 nm, 400 nm, 500 nm, 600 nm, 700 nm, 800 nm, 900 nm, 1 μm, 2 μm, 3 μm, etc.

[0121] 6, 8, 10, 11, and 12, in an embodiment in which the heating element 12 is in a sheet shape, the heating element 12 is located on the central axis of the aerosol matrix 11, and the air duct holes 10a are distributed symmetrically around the heating element 12 in a plane perpendicular to the longitudinal direction of the aerosol matrix 11. In this embodiment, the sheet-shaped heating element 12 effectively increases the heating area of ​​the medium, improving the heating speed and uniformity of the entire medium and reducing the user's waiting time.

[0122] For example, as shown in FIGS. 15 to 27, in embodiments in which the heating element 12 is columnar, the heating element 12 is located on the central axis of the aerosol matrix 11, and the air duct holes 10a are distributed symmetrically about the origin with respect to the heating element 12 in a plane perpendicular to the longitudinal direction of the aerosol matrix 11. By making the distances from the heating element 12 to the symmetric air duct holes 10a the same, uniform heating is achieved. For example, in some embodiments, as shown in FIGS. 15 to 19, the air duct holes 10a are arranged in a ring shape with the heating element 12 at the center, and the ring shape may have one or more turns. In other embodiments, the air duct holes 10a are arranged in a matrix shape, with the heating element 12 located at the center of the matrix, and the number of rows and columns of the matrix may be the same or different, and the heating element 12 may occupy one point in the matrix (see FIGS. 23 and 24) or none of the points in the matrix (see FIG. 27).

[0123] The arrangement of the air duct holes 10a is not limited.

[0124] For example, all the air duct holes 10a are distributed along multiple trajectories, with each air duct hole 10a along one trajectory line being linearly arranged along a first direction, and multiple trajectory lines being arranged along a second direction, with the first and second directions not being parallel to each other. The first and second directions form a two-dimensional coordinate system on a plane, and the first and second directions can define the arrangement of the air duct holes 10a on the plane. That is, the air duct holes 10a are arranged regularly, which makes it convenient to process each air duct hole 10a according to a predetermined arrangement rule during molding.

[0125] For example, the air duct holes 10a on one trajectory line are arranged at equal intervals. This means that the distance between the centers of two adjacent air duct holes 10a is equal. The shapes and dimensions of the medium walls between two adjacent air duct holes 10a are approximately the same. This improves the uniformity of aerosol emission by the smoke-generating medium segment during the heating and inhalation process, which is beneficial to the uniformity of aerosol transport and heat reception, and further improves the user's inhalation experience.

[0126] The first direction may be a straight line or a curved line, and the second direction may be a straight line or a curved line.

[0127] For example, in some embodiments, as shown in Figures 16-18, 19, and 20, the air duct holes 10a in one trajectory line are arranged along a circumferential direction around the center of the aerosol matrix 11, i.e., arranged around the circumference of the heating element 12, and the multiple trajectory lines are arranged along a radial direction of the aerosol matrix 11. That is, the first direction is the circumferential direction around the center of the aerosol matrix 11, and the second direction is the radial direction. The air duct holes 10a are arranged concentrically.

[0128] In an embodiment in which the first direction is a circumferential direction around the center of the aerosol matrix 11, the diameter of the air duct holes 10a at each trajectory line gradually increases radially outward, as shown in FIG. 6 . That is, the diameter of the air duct holes 10a decreases toward the center of the aerosol matrix 11, and the diameter of the air duct holes 10a increases toward the farther side from the center of the aerosol matrix 11. By gradually decreasing the diameter of the air duct holes 10a from the outside to the inside, the heating rate of the entire medium is controlled, resulting in more uniform aerosol release within the medium. Specifically, the smaller the diameter of the air duct holes 10a and the greater the amount of medium, the slower the overall heat conduction rate, and vice versa. In this way, the medium has good aerosol release efficiency during the later stages of inhalation, enhancing the user's experience.

[0129] In some other embodiments, as shown in Figures 8, 10, 23, 24, and 27, the air duct holes 10a in one trajectory line are arranged linearly along a first direction, and multiple trajectory lines are arranged parallel to a second direction, and the first direction is perpendicular to the second direction. For example, the air duct holes 10a are arranged in a matrix.

[0130] The contour shape of the aerosol-generating medium 10 in a plane perpendicular to the longitudinal direction of the aerosol-generating medium 10 is not limited, and may be, for example, a circle, an ellipse, a polygon, or the like, and is not limited here.

[0131] Illustratively, the contour and dimensions of the aerosol-generating medium 10 are determined by the aerosol matrix 11, i.e., the contour and dimensions of the aerosol matrix 11 and the contour and dimensions of the aerosol-generating medium 10 are similar.

[0132] For illustrative purposes, the embodiment of the present invention will be described taking the aerosol-generating medium 10 as having a cylindrical shape. That is, the cross-sectional outline of the aerosol-generating medium 10 is approximately circular. Since the cylindrical aerosol-generating medium 10 has a regular outer shape, the difficulty of the manufacturing process can be reduced.

[0133] For example, the maximum dimension of the contour of the aerosol-generating medium 10 in a plane perpendicular to the longitudinal direction of the aerosol-generating medium 10 is 4 mm to 10 mm. For example, the dimensions are 4 mm, 5 mm, 6 mm, 6.5 mm, 7 mm, 8 mm, 9 mm, and 10 mm. This size range provides the aerosol-generating medium 10 with good structural strength and allows the user to easily incorporate food.

[0134] Here, the maximum dimension of the contour of the aerosol-generating medium 10 refers to the distance between the two farthest points on the contour of the aerosol-generating medium 10 in a plane perpendicular to the longitudinal direction of the aerosol-generating medium 10. For example, if the contour of the aerosol-generating medium 10 is cylindrical, the maximum dimension of the contour of the aerosol-generating medium 10 is the diameter of the circle. If the contour of the aerosol-generating medium 10 is elliptical, the maximum dimension of the contour of the aerosol-generating medium 10 is the major axis of the ellipse.

[0135] For example, the maximum dimension of the contour of the aerosol-generating medium 10 is 6 mm to 8.6 mm in a plane perpendicular to the longitudinal direction of the aerosol-generating medium 10. For example, it may be 6 mm, 6.5 mm, 7 mm, 7.4 mm, 7.7 mm, 8 mm, or 8.6 mm.

[0136] In some embodiments, the air passage holes 10 a according to embodiments of the present invention extend along a straight line, ie, approximately parallel to the central axis of the aerosol matrix 11 .

[0137] In some other embodiments, the air duct holes 10a extend along a curve, for example, helically to form a spiral air duct, as shown in Figures 13 and 14. In this way, the gas flow velocity in the air duct holes 10a is improved to increase the aerosol extraction efficiency (the radial path is the same, but the path the gas takes through the medium is increased, increasing the air flow velocity and the contact area between the air flow and the medium surface, thereby increasing the aerosol extraction efficiency from the medium).

[0138] Illustratively, there are generally two or more spiral air passages, which are arranged symmetrically around the heating element 12 .

[0139] For example, the aerosol-generating matrix 11 has a one-piece structure. Specifically, the aerosol-generating matrix 11 is not formed by bonding multiple independent sub-blocks together by adhesive or other means, but is formed directly into the desired shape using a mold. In this way, the aerosol-generating matrix 11 has good structural strength and is less likely to disintegrate.

[0140] Below, 19 specific examples of the aerosol-generating medium will be briefly introduced with reference to the drawings.

[0141] First Example 6 and 7, in this embodiment, the passage has a plurality of air passage holes 10a, and the number of heating elements 12 is one.

[0142] The heating element 12 is in the form of a flat sheet and is provided on the central axis of the aerosol matrix 11. All the air passage holes 10a are arranged mirror-symmetrically with respect to the heating element 12.

[0143] The air passage hole 10a extends along a straight line.

[0144] In this embodiment, no air channel grooves 10b are provided on the outer circumferential surface of the aerosol matrix 11. It will be appreciated that in other embodiments, one or more air channel grooves 10b may be provided on the outer circumferential surface of the aerosol matrix 11.

[0145] Some of the air duct holes 10a are arranged concentrically, and the diameter of the air duct holes 10a gradually increases radially outward. The diameters of the air duct holes 10a on the same circle are similar.

[0146] A plurality of air passage holes 10a can be arranged on both sides of the heating element 12 and on the radially inner side of the innermost circle so as to pass through.

[0147] Prefabricated holes 10c are provided inside the aerosol matrix 11, penetrating both ends of the aerosol matrix 11 along the longitudinal direction. The heating element 12 is fitted into the prefabricated holes 10c, and both ends of the heating element 12 along the longitudinal direction are located inside the aerosol matrix 11; that is, the length of the heating element 12 is shorter than the length of the aerosol matrix 11. When the heating element 12 is fitted into the prefabricated holes 10c, depressions are formed in the prefabricated holes 10c outside both ends of the heating element 12. The depressions can change the aerosol flow rate and extend the contact time between the airflow and the medium, improving the heating efficiency of the medium and enhancing the consumer's inhalation experience.

[0148] Second Example As shown in Figures 8 and 9, in this embodiment, the configuration of the aerosol-generating medium 10 is almost the same as that of the first embodiment shown in Figure 6, and differs mainly in that multiple air channel grooves 10b are provided on the circumferential surface of the aerosol matrix 11 in this embodiment, and that prefabricated holes 10c are not provided in the aerosol matrix 11.

[0149] In this embodiment, the plurality of air channel grooves 10b are uniformly distributed along the circumferential direction of the aerosol matrix 11.

[0150] The heating element 12 is completely enclosed within the aerosol matrix 11 so as not to be exposed on the outer surface of the aerosol matrix 11 .

[0151] In this embodiment, the air passage holes 10a are arranged in a row, and the first direction and the second direction are perpendicular to each other and are both linear directions.

[0152] The number of air duct holes 10a on one track line is not exactly the same; for example, the number of air duct holes 10a on some of the track lines is five, and the number of air duct holes 10a on other track lines is three, etc.

[0153] Third Example As shown in Figure 10, in this embodiment, the configuration of the aerosol generating medium 10 is almost the same as that of the second embodiment shown in Figures 8 and 9, and differs mainly in that a prefabricated hole 10c is provided in this embodiment and that the heating element 12 is provided so as to penetrate through the prefabricated hole 10c.

[0154] Fourth Example As shown in Figure 11, in this embodiment, the configuration of the aerosol-generating medium 10 is almost the same as that of the third embodiment shown in Figure 10, and differs mainly in that multiple air channel grooves 10b are provided on the circumferential surface of the aerosol matrix 11 in this embodiment.

[0155] Fifth Example As shown in Figure 12, in this embodiment, the configuration of the aerosol-generating medium 10 is almost the same as that of the first embodiment shown in Figure 6, and differs mainly in that multiple air channel grooves 10b are provided on the circumferential surface of the aerosol matrix 11 in this embodiment, and the hole diameter of each air channel hole 10a is the same.

[0156] Sixth Example 13 and 14, in this embodiment, the air duct hole 10a extends in a spiral shape, i.e., forms a spiral air duct. The spiral air duct is advantageous for increasing the aerosol extraction efficiency (assuming the same suction resistance, the length of the path the gas flows through in the spiral air duct is increased, and the flow velocity of the airflow and the contact area between the airflow and the hole wall of the air duct hole 10a are increased, thereby increasing the aerosol extraction efficiency).

[0157] A prefabricated hole 10c is provided in the aerosol matrix 11, and the heating element is provided so as to penetrate through the prefabricated hole 10c.

[0158] In this embodiment, the aerosol matrix 11 is not provided with air channel grooves, but only with air channel holes 10a.

[0159] Seventh Example As shown in FIG. 15, in this embodiment, the heating element 12 is columnar and is located on the central axis of the aerosol matrix 11 .

[0160] The air duct holes 10a are in the shape of an annular fan. The multiple air duct holes 10a are uniformly arranged around the circumferential direction of the heating element 12. For example, when the number of air duct holes 10a is three, the central angle corresponding to each air duct hole 10a is 120°. When the number of air duct holes 10a is four, the central angle corresponding to each air duct hole 10a is 90°. When the number of air duct holes 10a is six, the central angle corresponding to each air duct hole 10a is 60°.

[0161] In this embodiment, a radial partition wall 111 is provided between two adjacent air passage holes 10a, and the thickness of any portion of one radial partition wall 111 may be the same or different.

[0162] In this embodiment, the annular fan-shaped air duct hole 10a can efficiently increase the flow rate of fresh airflow within the air duct hole 10a, reduce the proportion of aerosol in the airflow, and lower the temperature of the aerosol after extraction. Therefore, when a user inhales intermittently, less aerosol is wasted and the aerosol utilization rate can be increased.

[0163] Eighth Example As shown in FIG. 16, in this embodiment, based on the seventh embodiment shown in FIG. 15, an arc-shaped partition wall 112 is added to the air duct hole 10a, and one air duct hole 10a in the seventh embodiment is partitioned into a plurality of air duct holes 10a arranged along the radial direction, making the volume of the air duct holes 10a smaller and increasing the number.

[0164] The thickness of the arcuate partition wall 112 is the same as that of the radial partition wall 111. In other embodiments, the thicknesses of the two may be different.

[0165] The arc-shaped partition walls 112 of each layer have the same thickness along the radial direction, and in other embodiments, the thickness of the arc-shaped partition walls 112 of each layer may be different, for example, the thickness may gradually increase or decrease radially inward.

[0166] The radial width of the air passage holes 10a in each layer is the same, and in other embodiments, the thickness of the arc-shaped partition walls 112 in each layer may be different, for example, the width may gradually increase or decrease radially inward.

[0167] In this embodiment, the air duct holes 10a are not in communication with each other, that is, the airflow in any air duct hole 10a can flow into the other air duct holes 10a via the micropores.

[0168] In this embodiment, the radial partition walls 111 of the air passage holes 10a in each layer are aligned so as to be positioned on the same straight line.

[0169] Ninth Example As shown in FIG. 17, the construction of the aerosol-generating medium 10 is almost the same as that of the eighth embodiment shown in FIG. 16, but differs mainly in that at least two air passage holes 10a are in communication with each other.

[0170] Specifically, at least one arc-shaped partition wall 112 is provided with a communication hole 11a, and / or at least one radial partition wall 111 is provided with a communication hole 11a.

[0171] Tenth Example As shown in Figure 18, the configuration of the aerosol-generating medium 10 is almost the same as that of the eighth embodiment shown in Figure 16, with the main difference being that the radial partition walls 111 of the air duct holes 10a of each layer are arranged offset so as not to be in the same straight line.

[0172] Eleventh Example As shown in Figures 19 and 20, in this embodiment, the configuration of the aerosol-generating medium 10 is almost the same as in the first embodiment, with the main differences being that the heating element 12 in this embodiment is solid and cylindrical, and that the air duct holes 10a are distributed in multiple concentric rings.

[0173] Specifically, in this embodiment, one orbital line is a circle, the first direction is the circumferential direction around the heating element 12, the second direction is the radial direction, and all the orbital lines are distributed concentrically.

[0174] In this embodiment, no air channel grooves 10b are provided on the outer circumferential surface of the aerosol matrix 11. It will be appreciated that in other embodiments, one or more air channel grooves 10b may be provided on the outer circumferential surface of the aerosol matrix 11.

[0175] Twelfth Example As shown in Figure 21, in this embodiment, the configuration of the aerosol generating medium 10 is almost the same as in the 11th embodiment, and the main difference is that the heating element 12 in this embodiment is hollow and columnar, i.e., the heating element 12 has an almost hollow tube structure.

[0176] Specifically, the heating element 12 has a through hole 12a that penetrates both ends of the heating element 12 along the longitudinal direction, and the diameter of the tube of the heating element 12 is small, so the inside of the through hole 12a is empty, and no part of the aerosol matrix 11 is filled in the through hole 12a.

[0177] The heating area of ​​the hollow columnar heating element 12 relative to the aerosol matrix 11 is the same as that of the solid heating element 12. In this embodiment, the through-hole 12a and the prefabricated hole 10c communicate with each other, forming a path for airflow, reducing suction resistance and improving the user experience.

[0178] In this embodiment, the air duct holes 10a are arranged concentrically. The diameters of the air duct holes 10a in the same circle may be the same or different.

[0179] In this embodiment, no air channel grooves 10b are provided on the outer circumferential surface of the aerosol matrix 11. It will be appreciated that in other embodiments, one or more air channel grooves 10b may be provided on the outer circumferential surface of the aerosol matrix 11.

[0180] Thirteenth Example As shown in Figure 22, in this embodiment, the configuration of the aerosol generating medium 10 is almost the same as that of the 12th embodiment shown in Figure 21, and the main difference is that a blind passage 10d with at least one end closed along the longitudinal direction is provided inside the aerosol matrix 11 in this embodiment.

[0181] It is preferable that both ends of the blind road 10d are closed.

[0182] During the process of the user intermittently inhaling, the blind passage 10d can increase the internal temperature of the aerosol matrix 11 when the user is not inhaling, thereby reducing the output of the aerosol generating device 200, lengthening the duration of a single flight of the aerosol generating device 200, and also improving the heating uniformity of the entire aerosol matrix 11 and the consistency of aerosol release.

[0183] In this embodiment, no air channel grooves 10b are provided on the outer circumferential surface of the aerosol matrix 11. It will be appreciated that in other embodiments, one or more air channel grooves 10b may be provided on the outer circumferential surface of the aerosol matrix 11.

[0184] Fourteenth Example As shown in Figure 23, in this embodiment, the first and second directions in which the air duct holes 10a are arranged are perpendicular to each other and are straight lines. The air duct holes 10a are arranged in a matrix, and the prefabricated holes 10c occupy one of the points in the matrix.

[0185] The aerosol matrix 11 has a plurality of air channel grooves 10b formed on its circumferential surface.

[0186] Fifteenth Example As shown in Figures 24, 25, and 26, in this embodiment, the heating element 12 is hollow and columnar, i.e., the heating element 12 has a substantially hollow tubular structure. Through-holes are formed in the internal space of the heating element 12. The outer diameter of the heating element 12 is larger than the outer diameter of the heating element 12 shown in Figures 20 and 21, for example, 1.5 to 3 times the outer diameter of the heating element 12 according to the embodiment shown in Figures 20 and 21. The inner diameter of the through-hole 12a according to this embodiment is larger than the inner diameter of the through-hole 12a of the heating element 12 in Figure 21, for example, 1.5 to 3 times the inner diameter of the through-hole 12a according to the embodiment shown in Figure 21.

[0187] In this embodiment, the holes 12 a are filled with the aerosol matrix 11 .

[0188] In some embodiments, the heating element 12 is attached by inserting a tubular heating element 12 into the aerosol matrix 11 from one end of the aerosol matrix 11 after the aerosol matrix 11 is formed.

[0189] The other end of the heating element 12 may be flush with the other end face of the aerosol matrix 11 or may be located completely inside the aerosol matrix 11 .

[0190] In some other embodiments, the heating element 12 is placed in a mold, and then the material required for the aerosol matrix 11 is poured into the mold and molded by a method such as die casting.

[0191] In this embodiment, no air channel grooves 10b are provided on the outer circumferential surface of the aerosol matrix 11. It will be appreciated that in other embodiments, one or more air channel grooves 10b may be provided on the outer circumferential surface of the aerosol matrix 11.

[0192] Sixteenth Example As shown in FIG. 27, the heating element 12 is columnar, a prefabricated hole 10c is provided in the aerosol matrix 21, and the heating element 12 is provided so as to penetrate the prefabricated hole 10c.

[0193] The air passage holes 10a are arranged in a matrix, for example, a 4x4 matrix, but the heating elements 12 do not occupy any points of the matrix.

[0194] Seventeenth Example 28 and 29, in this embodiment, the heating element 12 is plate-shaped, and the surface of the plate-shaped heating element 12 is not parallel to the longitudinal direction of the aerosol matrix 11. It is preferable that the surface of the heating element 12 is perpendicular to the longitudinal direction of the aerosol matrix 11.

[0195] In this embodiment, an induction coil can be easily installed on the bottom wall of the heating chamber 200a of the aerosol generation device 200, and heating is performed at the end.

[0196] For example, in a plane perpendicular to the longitudinal direction of the aerosol matrix 11, at least one air duct hole 10a is located within the projection range of the heating element 12, and a through-hole 12b is provided in the heating element 12 at a position corresponding to the air duct hole 10a, with the through-hole 12b being located in the path of the airflow through the air duct hole 10a. In this way, the heating element 12 does not affect the flow of the airflow through the air duct hole 10a. The number and positions of the through-holes may correspond one-to-one to the number and positions of the air duct holes, or there may be more through-holes than the number of the air duct holes, with each air duct hole corresponding to one through-hole.

[0197] In this embodiment, no air channel grooves 10b are provided on the outer circumferential surface of the aerosol matrix 11. It will be appreciated that in other embodiments, one or more air channel grooves 10b may be provided on the outer circumferential surface of the aerosol matrix 11.

[0198] 18th Example As shown in Figure 30, in this embodiment, the configuration of the aerosol-generating medium 10 is almost the same as that of the embodiment shown in Figure 20, with the main difference being that all the air duct holes 10a in this embodiment penetrate the same end of the aerosol matrix 11 and that the other end of the air duct holes 10a is a blind end.

[0199] 19th Example As shown in Figure 31, in this embodiment, the configuration of the aerosol-generating medium 10 is almost the same as that of the embodiment shown in Figure 20, with the main difference being that in this embodiment, some of all the air duct holes 10a penetrate one end of the aerosol matrix 11, while the remaining air duct holes 10a penetrate the other end of the aerosol matrix 11.
