[0046] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0047] This application provides an aerosol generating article 10, please refer to... Figures 1 to 3 The aerosol generating article 10 includes functional segments 14 and media segments 11 arranged along a first direction. The functional segments 14 are located near the lip end of the aerosol generating article 10. The media segment 11 has a diameter greater than or equal to 5 mm and less than or equal to 6.8 mm. The media segment 11 includes a first packaging layer and an aerosol generating matrix. The aerosol generating matrix fills the interior of the first packaging layer and includes a tobacco medium and a smoking medium, with the smoking medium loaded onto the tobacco medium. The average filling density of the aerosol generating matrix is greater than or equal to 0.4 g / cm³. 3 And less than or equal to 0.6 g / cm³ 3 .
[0048] It should be noted that the aerosol generating article 10 of this application embodiment can be used for suction by ignition or by heating without combustion. In this application embodiment, the aerosol generating article 10 is described as being used for suction by heating without combustion.
[0049] This application also provides an aerosol generation system 100, please refer to... Figures 1 to 3 The aerosol generation system 100 includes the aerosol generation article 10 and the aerosol generation device 20 according to any embodiment of this application.
[0050] The aerosol generating product 10 is used in conjunction with the aerosol generating device 20.
[0051] Aerosol generating article 10 is used to generate aerosols when heated for users to inhale.
[0052] In this embodiment, the aerosol-generated article 10 is generally cylindrical. The cylindrical shape can be circular (i.e., with a circular cross-section), prismatic (i.e., with a polygonal cross-section), elliptical (i.e., with an elliptical cross-section), etc., and is not limited thereto.
[0053] Here, the number of aerosol-generated products 10 can be one or more.
[0054] In the embodiments of this application, "multiple" refers to two or more items.
[0055] The proximal end refers to the end of the aerosol generating article 10 that is closer to the user when the user uses it, while the distal end refers to the end of the aerosol generating article 10 that is farther away from the user when the user uses it. In other words, the two ends of the aerosol generating article 10 along the first direction are the proximal end and the distal end, respectively.
[0056] For example, functional segment 14 includes a first functional segment 141, which is configured as a filtering segment.
[0057] For example, the aerosol generated by the heated aerosol generating article 10 can flow through a filtration section, which can filter out large particulate components and unwanted impurities in the aerosol. That is, the aerosol generated by the heated aerosol generating article 10 is filtered through the filtration section and then inhaled by the user.
[0058] For example, please refer to Figures 1 to 3 Functional segment 14 includes a second functional segment 142. A first functional segment 141 is disposed at one end of the second functional segment 142 away from the medium segment 11. The second functional segment 142 includes a cooling segment and / or a support segment.
[0059] For example, the second functional segment 142 includes a cooling segment disposed at at least one end of the filter segment along the first direction, and the cooling segment can cool the flowing aerosol.
[0060] For example, the aerosol generated by the heated aerosol generating article 10 can first flow through a cooling section for cooling, and then the cooled aerosol flows through a filtration section, which can filter out large particles and unwanted impurities in the aerosol. That is, the aerosol generated by the heated aerosol generating article 10 is cooled and filtered in sequence through the cooling section and the filtration section before being inhaled by the user.
[0061] For example, the second functional segment 142 includes a support segment that can support the aerosol-generated article 10. Of course, the support segment can also cool the flowing aerosol.
[0062] In some embodiments, please refer to Figures 1 to 3 The second functional section 142 includes a cooling section and a support section. The support section and the cooling section can also be combined into one section, that is, the same structural component can simultaneously achieve the functions of support and cooling. This type of structural form, where the support section and the cooling section are called a support-cooling section.
[0063] This simplifies the structure of the aerosol-generating product 10, reduces the investment in production equipment and materials for the aerosol-generating product 10, and saves costs.
[0064] For example, the aerosol generating article 10 includes a front plug section 12, a medium section 11, a support cooling section, and a filter section arranged in a first direction.
[0065] For example, the aerosol generating article 10 also includes a coating layer 13, which wraps around the periphery of the front plug section 12, the medium section 11, the support cooling section and the filter section.
[0066] For example, the material of the wrapping layer 13 is one or more of paper, paper tube, tin foil, and aluminum foil.
[0067] For example, the wrapping layer 13 may be bottom-ventilated or bottom-sealed.
[0068] Of course, in other embodiments, functional segment 14 may also include a suction resistance adjustment segment. The aerosol generated by heating the aerosol generating product 10 first flows through the suction resistance adjustment segment, then through the cooling segment for cooling, and finally through the filtration segment. The filtration segment can filter out large particles and unwanted impurities in the aerosol. That is, the aerosol generated by heating the aerosol generating product 10 passes through the suction resistance adjustment segment, the cooling segment, and the filtration segment in sequence for suction resistance adjustment, cooling, and filtration before being drawn in by the user.
[0069] Here, the aerosol generating article 10 includes at least a functional section 14 with a filtering effect, or a functional section 14 with effects such as regulating aerosol temperature, regulating aerosol flavor, regulating suction resistance, aggregating aerosol (aggregation section), and promoting mixing of aerosol with cold air.
[0070] It should be noted that functional segments 14 can be used in combination. Users can add or remove at least some of the functional segments 14 as needed to adjust the suction resistance.
[0071] For example, the functional segment 14 is columnar with a circular or elliptical cross-section. When the functional segment 14 contains multiple functional segments 14 that have filtering or cooling effects, the longitudinal centers of each functional segment 14 are aligned coaxially.
[0072] For example, the materials used in the filter section include, but are not limited to, cellulose acetate, polyethylene terephthalate, polypropylene fiber, cellulose paper filter rods, recycled tobacco leaves, polylactic acid fiber, resin, plant polysaccharides, and other materials. The filter section can filter and adsorb aerosols, thereby improving the purity and comfort of the aerosols.
[0073] The heating element 22 can heat the medium segment 11 in any way. Exemplarily, the heating methods include center heating and peripheral heating. Center heating refers to the heating element being inserted into the medium segment 11 to heat it from the inside out. Peripheral heating refers to the heating element being positioned around the medium segment 11 to heat it from the outside in. These heating methods can specifically be at least one of resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc., and are not specifically limited here.
[0074] For example, please refer to Figure 1 The aerosol generating apparatus 20 includes a heating element 22, which is used to heat the aerosol generating article 10 to generate aerosol.
[0075] Specifically, the aerosol generating device 20 includes a housing and a power supply component disposed within the housing. The housing has a receiving chamber 21. The power output section of the power supply component is disposed within the receiving chamber 21 or around the side wall of the receiving chamber 21. When the portion of the aerosol generating article 10 located in the first direction range is inserted into the receiving chamber 21, the power output section transmits electrical energy to the heating element 22 in a contact or non-contact manner. The heating element 22 receives energy from the outside and generates heat, thereby heating the aerosol generating article 10 and generating aerosol.
[0076] In this embodiment, the first direction does not specifically refer to the direction in which the outer contour of the aerosol-generating article 10 is longest. The length of the aerosol-generating article 10 along the first direction may be longer, shorter, or the same as the length in other directions.
[0077] For example, when the aerosol generating article 10 has a cylindrical outline, the first direction is the axial direction of the aerosol generating article 10. It should be noted that even when the axial length of the aerosol generating article 10 is less than its diameter, the first direction of the aerosol generating article 10 is still the axial direction. As another example, when the aerosol generating article 10 has a cuboid outline, the first direction is still the direction defined above. The first direction of the aerosol generating article 10 can be any of the length, width, or height of the cuboid.
[0078] For example, tobacco media include at least one of filamentous media, granular media, sheet-like media, powdered media, and columnar media.
[0079] Here, powdered media refers to tobacco media with a particle size of less than or equal to 0.18 mm.
[0080] Particulate media refers to tobacco media with a particle size greater than 0.18 mm.
[0081] Here, the tobacco medium can be tobacco leaves or reconstituted tobacco medium cut into shreds, granules, flakes, powder, columns or other shapes.
[0082] Here, the smoke-generating medium is the smoke-generating agent, which can be selected from one or more of the following: monohydric alcohols; dihydric alcohols; polyhydric alcohols; monocarboxylic acids, dicarboxylic acids, or esters formed from polycarboxylic acids and fatty alcohols. Using the above-mentioned smoke-generating agent components is beneficial for providing a large amount of smoke, thereby increasing the amount of smoke generated by the aerosol-generating matrix.
[0083] For example, tobacco leaves or reconstituted tobacco media are first cut into filaments, granules, flakes, pellets, powders, columns or other shapes to form tobacco media. Then, a smoke-generating medium is loaded onto the tobacco media to form an aerosol-generating matrix. The aerosol-generating matrix is then filled into the interior of the first packaging layer to form media segment 11. This manufacturing process is simple, improves production efficiency and reduces manufacturing costs.
[0084] The wrapping layer 13 has a certain degree of hardness, which can play a certain protective role for the medium section 11, reduce the surface area of the medium section 11 directly exposed to the outside world, thereby reducing the probability of the medium section 11 becoming damp and deteriorating due to contact with air. At the same time, it reduces the probability of the medium section 11 coming into contact with other components in the aerosol generating device 20 and causing pollution.
[0085] The diameter of the medium segment 11 is greater than or equal to 5 mm and less than or equal to 6.8 mm. For example, it is a point value of any one of 5 mm, 5.2 mm, 5.3 mm, 5.5 mm, 5.8 mm, 6 mm, 6.2 mm, 6.5 mm, 6.8 mm, or a point value between any two of them.
[0086] Here, the larger the diameter of the medium segment 11, the more tobacco medium and smoke-generating medium it includes, and the greater the amount of smoke. However, during the peripheral heating process, the time required for heat to be transferred to the center of the medium segment 11 is longer. The smaller the diameter of the medium segment 11, the shorter the time required for heat to be transferred to the center of the medium segment 11 during the peripheral heating process.
[0087] By setting the diameter of the medium segment 11 to be greater than or equal to 5 mm and less than or equal to 6.8 mm, a fine-sized medium segment 11 is formed. This improves the heating uniformity and stability of the medium segment 11, increases the extraction efficiency and utilization rate of the medium segment 11, enhances the consistency of aerosol release, improves aerosol quality, and also reduces energy consumption.
[0088] In some embodiments, the average packing density of the aerosol generation matrix is greater than or equal to 0.4 g / cm³. 3 And less than or equal to 0.6 g / cm³ 3 .
[0089] The average packing density of the aerosol generation matrix can be 0.4 g / cm³. 3 0.42g / cm 3 0.43g / cm 3 0.45g / cm 3 0.48g / cm 3 0.5g / cm 3 0.52g / cm 3 0.53g / cm 3 0.55g / cm 3 0.58g / cm 3 0.6g / cm 3 The point value of any one of them or the point value between any two.
[0090] Here, when the average packing density of the aerosol generation matrix is greater than 0.6 g / cm³ 3 When the filling density of the aerosol generating matrix is too high, the absorption resistance of the medium section 11 is large, and the amount of smoke is small. When the average filling density of the aerosol generating matrix is less than 0.4 g / cm³, the aerosol generating matrix will generate more smoke. 3 At this time, the aerosol generating matrix cannot completely fill the first packaging layer, resulting in insufficient stiffness of the medium section 11, a small amount of smoke, poor consistency of the medium section 11, and low vaping satisfaction. Therefore, by setting the average filling density of the aerosol generating matrix to be greater than or equal to 0.4 g / cm³... 3 And less than or equal to 0.6 g / cm³ 3 This allows the medium section 11 to have appropriate suction resistance, as well as a certain stiffness and amount of smoke, which helps to improve the consistency of the medium section 11 and the satisfaction of inhalation.
[0091] This application provides an aerosol generating article 10, including a functional segment 14 and a medium segment 11. The medium segment 11 is used to generate aerosols. By setting the diameter of the medium segment 11 to be greater than or equal to 5 mm and less than or equal to 6.8 mm, this appropriate diameter range not only ensures that the aerosol generating article 10 has a certain amount of smoke, but also improves the heating uniformity and stability of the medium segment 11, increases the extraction efficiency and utilization rate of the medium segment 11, enhances the consistency of aerosol release, improves aerosol quality, and reduces energy consumption. Furthermore, the aerosol generating matrix of the medium segment 11 is configured to include a tobacco medium and a smoking medium, with the smoking medium loaded onto the tobacco medium. This manufacturing process is simple, improves production efficiency, and reduces manufacturing costs. Moreover, by setting the average filling density of the aerosol generating matrix to be greater than or equal to 0.4 g / cm³... 3 And less than or equal to 0.6 g / cm³ 3 This allows for appropriate suction resistance in the medium section, along with a certain degree of stiffness and smoke volume, which helps improve the consistency of the medium section and the satisfaction of vaping.
[0092] In some embodiments, the ratio of the length of the medium segment 11 to the length of the aerosol-generating article 10 is greater than or equal to 0.25 and less than or equal to 1.
[0093] The ratio of the length of the medium segment 11 to the length of the aerosol-generated product 10 can be any one of 0.25, 0.28, 0.3, 0.32, 0.35, 0.38, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, or 1, or any value between the two.
[0094] With a fixed length of aerosol generating product 10, the larger the ratio of the length of the medium section 11 to the length of the aerosol generating product 10, the longer the medium section 11 is; conversely, the smaller the ratio, the shorter the medium section 11 is. A longer medium section 11 contains more effective substances and produces a larger amount of smoke, while a shorter medium section 11 improves ease of use and production efficiency.
[0095] In this embodiment, by setting the ratio of the length of the medium segment 11 to the length of the aerosol-generated product 10 between 0.25 and 1, the medium segment 11 has sufficient smoke volume, while also improving the ease of use and production efficiency of the medium segment 11.
[0096] In some embodiments, the suction resistance of the dielectric segment 11 is greater than or equal to 400 mmWG and less than or equal to 900 mmWG.
[0097] Here, mmWG is a unit of hydrostatic pressure, representing millimeters of water column. That is to say, the suction resistance of the aerosol-generated product 10 is greater than or equal to 400 mm of water column and less than or equal to 900 mm of water column.
[0098] The suction resistance of the dielectric section 11 can be any one of 400mmWG, 450mmWG, 480mmWG, 500mmWG, 550mmWG, 600mmWG, 650mmWG, 700mmWG, 750mmWG, 800mmWG, 850mmWG, or 900mmWG, or any value between two of them.
[0099] By setting the suction resistance of the medium section 11 to be greater than or equal to 400 mmWG and less than or equal to 900 mmWG, it is beneficial to keep the suction resistance of the medium section 11 within an appropriate range, which can make the suction resistance of the aerosol generating product 10 appropriate and improve the user experience.
[0100] In some embodiments, the ratio of the weight of the smoke-generating medium to the weight of the tobacco medium is greater than or equal to 0.1.
[0101] In this embodiment, by setting the ratio of the weight of the smoke-generating medium to the weight of the tobacco medium to be greater than or equal to 0.1, the medium segment 11 can have a sufficient amount of smoke.
[0102] In some embodiments, please refer to Figures 1 to 4 The aerosol generating article 10 includes a front plug section 12, which is disposed at one end of the medium section 11 and located at the distal lip end of the aerosol generating article 10.
[0103] The front plug section 12 includes a second packaging layer 121 and a filling part. The filling part is formed by repeatedly bending a layered filling member 122 and is in a pleated shape. The filling part is disposed in the second packaging layer 121 to form a channel 123 extending from one end of the front plug section 12 to the other end within the second packaging layer 121.
[0104] For example, the wrapping layer 13 surrounds the periphery of the fore plug section 12 and the medium section 11.
[0105] The front plug section 12 is disposed at one end of the medium section 11 and located at the distal lip end of the aerosol generating product 10. On the one hand, during use, the front plug section 12 can effectively reduce the probability of the medium section 11 falling out of the second packaging layer 121; on the other hand, it can also effectively prevent the aerosol from condensing and flowing downward and remaining in the receiving chamber 21 of the aerosol generating device 20, thereby causing the internal contamination of the receiving chamber 21 and making it difficult to clean, and also preventing the problem of cross-contamination of flavors when sucking in different flavored aerosol generating products 10.
[0106] For example, the material of the pre-plug section 12 includes, but is not limited to, paper, non-woven fabric, rubber, polyethylene terephthalate, cellulose acetate, mineral-containing products, cellulose paper filter rods, plant polysaccharides, etc.
[0107] The shape of the cross-section of the second packaging layer 121 is not limited in a plane perpendicular to the axis of the aerosol-generating article 10. Generally, please refer to [link to relevant documentation]. Figure 4 The second packaging layer 121 has a circular cross-section. Circular means that the second packaging layer 121 has a wall thickness, therefore the cross-sectional shape of its inner and outer circumferential walls is circular. It can be understood that the second packaging layer 121 is typically made of paper material with a small thickness, for example, less than 1 mm; therefore, its cross-sectional shape can also be considered circular. That is, the outer wall surface of the second packaging layer 121 is cylindrical. With this structure, the aerosol generating product 10 of the second packaging layer 121 has an overall cylindrical structure. The cylindrical aerosol generating product 10 can be inserted into the receiving chamber 21 at various angles along its circumference, thus facilitating user use.
[0108] The front plug section 12 includes a wrapping layer 13 and a filling part. The filling part is formed by repeatedly bending a layered filling member 122 and is in a pleated shape. The filling part is disposed in the wrapping layer 13 to form a channel 123 extending from one end of the front plug section 12 to the other end within the wrapping layer 13.
[0109] Please see Figure 4 The pleated filling section, channel 123 extends along the axial direction of the front plug section 12. It can be understood that the cross-section of channel 123 is bent in a plane perpendicular to the axial direction of the front plug section 12.
[0110] External airflow can flow through channel 123 to medium section 11, thereby reducing the suction resistance of the front plug section 12 on the aerosol extraction. At the same time, since the filling part has a pleated shape, it has a better adsorption effect, which helps to reduce the probability that the aerosol will condense and flow downward and remain in the containment chamber 21 of the aerosol generating device 20.
[0111] In related technologies, the likelihood of the medium segment falling out of the second packaging layer can be effectively reduced by setting a front plug section. However, the front plug section will generate significant suction resistance to the aerosol, reducing the user's suction experience. Therefore, it is desirable to develop an aerosol generating product that can prevent the medium segment from falling out and effectively reduce the suction resistance generated by the front plug section on the aerosol.
[0112] The front plug section 12 of this embodiment consists of a wrapping layer 13 and a filling portion. The filling portion is formed by repeatedly bending a layered filler 122, resulting in a pleated shape. The filling portion is disposed within the wrapping layer 13 to create a channel 123 extending from one end of the front plug section 12 to the other. External airflow can flow through the channel 123 to the medium section 11, thereby reducing the suction resistance of the front plug section 12 on the aerosol extraction and improving the user experience. In other words, after the front plug section 12 of this embodiment is used to generate the aerosol product 10, it can reduce the probability of the medium section 11 falling out of the second packaging layer 121. At the same time, the front plug section 12 will not generate too much suction resistance on the aerosol extraction. In addition, after the suction is completed, the negative pressure generated during the suction process in the receiving chamber 21 will cause the aerosol to backflow / flow. The pleated filling part has a good adsorption effect and can adsorb the aerosol during the backflow / flow process. This helps to improve the problem of the receiving chamber 21 being contaminated by aerosol and difficult to clean, and also helps to improve the problem of cross-contamination of flavors that may occur when the product 10 is generated by suctioning different flavor aerosols.
[0113] During the suction process, the front plug section 12 can block the ambient air entering the aerosol generating product 10, which is beneficial for heat transfer, increases the heating rate, improves the efficiency of aerosol extraction and flow, and can prevent the aerosol generating matrix from detaching from the receiving chamber 21 of the aerosol generating device 20.
[0114] It should be noted that the cross-sectional shape of the front plug section 12 is not restricted here.
[0115] In some embodiments, please refer to Figures 1 to 4 On a plane perpendicular to the axial direction of the front plug section 12, the cross-section of the front plug section 12 is circular.
[0116] In other embodiments, the cross-sectional shape of the front plug section 12 is non-circular in a plane perpendicular to the axial direction of the front plug section 12.
[0117] As can be seen from the foregoing, on a plane perpendicular to the axial direction of the front plug section 12, the second packaging layer 121 is generally annular, while the cross-sectional shape of the front plug section 12 is non-circular. Therefore, after the front plug section 12 and the second packaging layer 121 are assembled, an outer peripheral air passage can be defined between the inner sidewall of the second packaging layer 121 and the outer sidewall of the wrapping layer 13.
[0118] The external airflow can flow to the medium section 11 through the peripheral air passage, thereby reducing the suction resistance of the front plug section 12 on the aerosol, which is beneficial to improving the user experience.
[0119] In addition, the peripheral airway is formed on the periphery of the front plug section 12. After the external airflow flows through the peripheral airway to the medium section 11, it can gradually flow from the periphery of the medium section 11 to the interior. This process can increase the utilization rate of the periphery of the medium section 11, thereby improving the suction performance of the aerosol generating product 10.
[0120] In one embodiment, the cross-sectional shape of the front plug section 12 is corrugated, polygonal, racetrack-shaped, fan-shaped, or elliptical.
[0121] It should be noted that since the filling part is located inside the wrapping layer 13, and the peripheral air passage is formed by the wrapping layer 13 and the second packaging layer 121, the shape of the cross section of the front plug section 12 can also be considered as the shape of the cross section of the area enclosed by the wrapping layer 13.
[0122] A polygon can have any number of sides and can be a regular polygon or a polygon with sides that are not all equal. For example, it can be a regular heptadecagon, a regular hexagon, or a regular pentagon.
[0123] The term "track shape" refers to a shape similar to an athletic track, consisting of two semicircles of the same radius and two parallel straight edges connected alternately.
[0124] In other words, the cross-section of the front plug section 12 can be any shape other than circular, which facilitates the formation of an outer peripheral airway between the front plug section 12 and the second packaging layer 121.
[0125] In one embodiment, the material of the second packaging layer 121 includes at least one of polylactic acid, fiber paper, polyethylene, and polyethylene terephthalate.
[0126] On the one hand, the second packaging layer 121 of this material has a certain degree of toughness, which allows it to be wound around the filling part to obtain the front plug section 12; on the other hand, the second packaging layer 121 of this material also has a certain degree of strength, which can reduce the probability of deformation of the front plug section 12, thus helping to improve the yield of the front plug section 12.
[0127] In one embodiment, the thickness of the second packaging layer 121 ranges from 0.05 mm to 0.5 mm. For example, it is a point value of any one of 0.05 mm, 0.1 mm, 0.15 mm, 0.18 mm, 0.2 mm, 0.25 mm, 0.27 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.46 mm, or 0.5 mm, or a point value between any two.
[0128] When the thickness of the second packaging layer 121 is less than 0.05mm, the second packaging layer 121 is weak due to its low thickness, making it prone to deformation after wrapping the internal filling part. This also leads to weak processing capability of the front plug section 12, resulting in a decrease in yield. When the thickness of the second packaging layer 121 is greater than 0.5mm, the thickness at the joint after molding is large (the joint is the overlap between the beginning and end of the second packaging layer 121), which results in a poor appearance of the front plug section 12 at the joint. Therefore, by setting the thickness of the second packaging layer 121 to 0.05mm-0.5mm, the second packaging layer 121 can have a certain degree of toughness and strength, while also helping to improve the problem of large thickness at the joint.
[0129] The material of filler 122 is not limited. For example, it can be various types of paper.
[0130] In related technologies, the filler 122 is made of polymer materials such as PLA (Polylactic acid), PET (Polyethylene glycol terephthalate), and CA (Cellulose acetate). During use, the front plug section 12 is prone to melting, shrinkage, and collapse when in contact with the heating element 22. This causes blockage of the channel 123 inside the front plug section 12, hindering the airflow from flowing through the channel 123 to the medium section 11 to extract aerosols. As a result, the suction resistance of the aerosol-generated product 10 increases significantly during the suction process, and chemical impurities are generated, affecting the user experience.
[0131] The paper-based filler 122 can operate normally at temperatures below 420°C, while the heating temperature of a typical aerosol generating device 20 is between 200°C and 320°C. Therefore, the filler 122 is less likely to melt or condense when in contact with the heating element 22, reducing the likelihood of blockage in the channel 123 inside the front plug section 12. This avoids a significant increase in suction resistance during the suction process. Furthermore, the paper material does not produce a chemical odor when heated. In addition, the paper-based filler 122 has good adsorption properties, and folding it into a pleated filling section further enhances its adsorption effect, thereby improving its adsorption performance for aerosols during the backflow / reverse flow process.
[0132] In one embodiment, the filler 122 is made of fiber paper.
[0133] The filler 122, made of fiber paper, gives the front plug section 12 better filling strength, which can improve the production qualification rate of the product during subsequent processing. At the same time, it can also improve the connection strength between the front plug section 12 and the medium section 11, and improve the problems of bending and breakage of aerosol generation product 10 caused by insufficient connection strength during use.
[0134] In addition, during the heating process, the fibrous odor produced by the fiber paper can be confined inside the fiber paper, thereby improving the user experience.
[0135] In one embodiment, the number of fillers 122 is one, and the width of filler 122 ranges from 30mm to 80mm.
[0136] The width of filler 122 can be any one of 30mm, 35mm, 38mm, 40mm, 45mm, 48mm, 50mm, 52mm, 55mm, 58mm, 60mm, 62mm, 65mm, 68mm, 70mm, 73mm, 75mm, 77mm, 80mm or any combination thereof.
[0137] It should be noted that, in a plane perpendicular to the axial direction of the front plug section 12, the cross-section of the filler 122 presents as a continuous line (e.g., Figure 4 As shown), the width of filler 122 is the total length of the line.
[0138] In this embodiment, on the one hand, the width of the filler 122 is not less than 30mm, thereby ensuring that there is sufficient filling in the first packaging layer and reducing the probability of the filler 122 falling out of the first packaging layer, which is conducive to ensuring the user's user experience; on the other hand, the width of the filler 122 is not greater than 80mm, that is, it will not cause the first packaging layer to have excessive filling, thereby effectively controlling the suction resistance of the front plug section 12.
[0139] In addition, when paper is used to manufacture the filler 122, the problem of excessive paper material used in the front plug section 12 will not occur. During user use, it can effectively improve the problems of heavy paper impurities in the aerosol-generated product 10 and poor user experience.
[0140] Preferably, the width of the filler 122 is in the range of 55mm-65mm.
[0141] In one embodiment, there are multiple fillers 122, and the sum of the widths of each filler 122 ranges from 30mm to 80mm.
[0142] The sum of the widths of each filler 122 can be any one of 30mm, 35mm, 38mm, 40mm, 45mm, 48mm, 50mm, 52mm, 55mm, 58mm, 60mm, 62mm, 65mm, 68mm, 70mm, 73mm, 75mm, 77mm, or 80mm, or any value between two of them.
[0143] For example, when there are multiple fillers 122, each filler 122 is bent to form a whole, that is, each layered filler 122 is embossed to form a wrinkled shape, and then multiple embossed fillers 122 are stacked to form a filling part. Alternatively, multiple fillers 122 are first stacked together, and the overall thickness of the stacked fillers 122 is larger than the thickness of a single filler 122, and then the stacked fillers 122 are embossed to form a wrinkled filling part.
[0144] In this embodiment, on the one hand, the width of each filler 122 is not less than 30mm, thereby ensuring that there is sufficient filling in the first packaging layer and reducing the probability of the filler 122 falling out of the first packaging layer, which is conducive to ensuring the user's user experience; on the other hand, the width of each filler 122 is not greater than 80mm, that is, the first packaging layer will not have the problem of excessive filling, thereby effectively controlling the suction resistance of the front plug section 12.
[0145] Similarly, when paper is used to manufacture the filler 122, the problem of excessive paper usage in the front plug section 12 will not occur. During user use, this can effectively improve the problems of heavy paper impurities in the aerosol-generated product 10 and poor user experience.
[0146] Preferably, the sum of the widths of each filler 122 ranges from 55mm to 65mm.
[0147] In one embodiment, the filler 122 is made of fiber paper with a basis weight range of 80 g / m³. 2 -120g / m 2 .
[0148] The basis weight of fiber paper can be 80 g / m². 2 90g / m 2 100g / m 2 105g / m 2 110g / m 2 115g / m 2 120g / m 2 The point value of any one of them or the point value between any two.
[0149] It should be noted that when the basis weight of the fiber paper is low, its processing performance is low, resulting in a relatively low yield of the front stopper section 12. When the basis weight is high, the paper impurities generated by the filler 122 are heavier during subsequent use, affecting the user's experience.
[0150] In this embodiment, the basis weight of the fiber paper is controlled at 80 g / m². 2 -120g / m 2 Within this range, it is possible to minimize the generation of paper impurities while ensuring the processing performance of the fiber paper. In other words, it can guarantee the yield of the pre-stop section 12 while also taking into account the user experience.
[0151] Preferably, the basis weight of the fiber paper is in the range of 100 g / m². 2 -110g / m 2 .
[0152] In some embodiments, the porosity of the foreplug section 12 is greater than or equal to 0.1 and less than or equal to 0.8.
[0153] The porosity of the front plug section 12 refers to the ratio of the sum of the cross-sectional areas of the air passages inside the front plug section 12 to the cross-sectional area of the front plug section 12.
[0154] The porosity of the front plug section 12 can be any one of 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 or any value between two of them.
[0155] The front plug section 12 has air passages of varying shapes (including regular and irregular shapes) in the radial direction of the aerosol-generating article 10.
[0156] It should be noted that when the porosity of the current plug section 12 is too high, the strength of the current plug section 12 is low during use, and the aerosol generating product 10 is prone to deformation and breakage during the suction process, which reduces the user experience; when the porosity of the current plug section 12 is too low, the suction resistance of the current plug section 12 is large during the suction process, which is not conducive to the user's suction of aerosol.
[0157] When the porosity is less than 0.1, the suction resistance of the front plug section 12 is relatively large, which is not conducive to the entry of outside air from the bottom, resulting in a decrease in aerosol extraction efficiency. When the porosity is greater than 0.8, the internal filling value is low, which is not conducive to the absorption of refluxed aerosols, resulting in a decrease in the cleaning ability of the containment chamber 21 and a decrease in the ability to detach the heated aerosol-generated product 10, thus reducing the user experience. In this embodiment, the porosity of the front plug section 12 is controlled within the range of 0.1-0.8. The front plug section 12 has high structural strength and does not generate too much suction resistance.
[0158] In some embodiments, the suction resistance of the front plug section 12 is the same along the direction from the distal lip end of the aerosol generating article 10 to the proximal lip end of the aerosol generating article 10.
[0159] In this embodiment, by setting the suction resistance of the front plug section 12 to be the same, it is beneficial to ensure the consistency of airflow within the front plug section 12, thereby improving the consistency of aerosol flow and enhancing the user's suction experience.
[0160] In some embodiments, the suction resistance of the front plug section 12 is reduced along the direction from the distal lip end to the proximal lip end of the aerosol generating article 10.
[0161] In this embodiment, by reducing the suction resistance of the front plug section 12 along the direction from the distal lip end to the proximal lip end of the aerosol generating article 10, the direction of airflow in the aerosol generating article 10 can be guided, which is beneficial to improving the user's suction experience.
[0162] In some embodiments, the length of the front plug section 12 ranges from 3 mm to 10 mm.
[0163] The length of the front plug section 12 can be any one of 3mm, 3.5mm, 4mm, 4.3mm, 4.6mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, and 10mm, or any value between two of them.
[0164] When the length of the front plug section 12 is less than 3mm, it is not conducive to the adsorption of the backflow aerosol after the front plug section 12 has finished suction, which easily leads to the condensation of aerosol in the aerosol generating device 20. When the length of the front plug section 12 is greater than 10mm, the suction resistance of the front plug section 12 is large, which affects the bottom air intake, thereby reducing the aerosol carrying efficiency and the suction experience. Therefore, it is more appropriate to set the length of the front plug section 12 between 3mm and 10mm.
[0165] In some embodiments, the suction resistance of the front plug section 12 is less than or equal to 15 Pa / mm.
[0166] By setting the suction resistance of the front plug section 12 to less than or equal to 15 Pa / mm, it is beneficial to keep the suction resistance of the front plug section 12 within an appropriate range, which can make the suction resistance of the aerosol generating product 10 appropriate and improve the user experience.
[0167] In some embodiments, please refer to Figures 1 to 3 The suction resistance of the front plug section 12 is less than that of the filter section.
[0168] In other words, the ratio of the suction resistance of the front plug section 12 to the suction resistance of the filter section is less than 1.0.
[0169] In this embodiment, by setting the suction resistance of the front plug section 12 to be less than that of the filter section, the suction resistance of the aerosol generating product 10 can be made appropriate, thereby improving the user experience.
[0170] In some embodiments, the suction resistance of the filter section ranges from 10 Pa / mm to 35 Pa / mm.
[0171] Here, the suction resistance of the filter section can be any one of 10Pa / mm, 12Pa / mm, 15Pa / mm, 18Pa / mm, 20Pa / mm, 22Pa / mm, 25Pa / mm, 28Pa / mm, 30Pa / mm, 33Pa / mm, or 35Pa / mm, or any value between two of them.
[0172] In this embodiment, by setting the suction resistance of the filter section between 10 Pa / mm and 35 Pa / mm, it is beneficial to keep the suction resistance of the filter section within an appropriate range, which means that the suction resistance of the aerosol generating product 10 is appropriate, thus improving the user experience.
[0173] In some embodiments, the length of the filter section ranges from 5mm to 12mm.
[0174] Here, the length of the filter segment can be any one of 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, or 12mm, or any combination thereof.
[0175] It can be understood that if the filter section is too short, it is not conducive to the screening of large molecules in aerosols, which can easily lead to a coarse aroma and a decline in aroma quality; if the filter section is too long, the filtration of aerosols will increase, leading to an increase in the interception rate, which in turn will reduce the transmission efficiency, resulting in a decrease in aerosol utilization and a reduction in the user experience.
[0176] In this embodiment, by setting the length of the filter section to 5mm-12mm, it is beneficial to screen macromolecules in the aerosol without affecting the aerosol utilization rate, thereby improving the aroma quality.
[0177] For example, the ratio of the length of the second functional segment 142 to the length of the aerosol-generating article 10 is greater than or equal to 0.3.
[0178] Here, since the second functional section 142 includes a cooling section and / or a support section, when the ratio of the length of the second functional section 142 to the length of the aerosol generating product 10 is less than 0.3, the length of the cooling section and / or the support section is too short, which is not conducive to cooling the aerosol.
[0179] In this embodiment, by making the ratio of the length of the second functional segment 142 to the length of the aerosol generating product 10 greater than or equal to 0.3, it is beneficial to cool the aerosol, thereby further improving the cooling effect of the cooling segment.
[0180] In some embodiments, please refer to Figures 1 to 3 The diameter of the second functional segment 142 ranges from 4.8mm to 6.8mm.
[0181] The diameter of the second functional segment 142 can be any one of 4.8mm, 5mm, 5.2mm, 5.3mm, 5.5mm, 5.6mm, 5.8mm, 6mm, 6.2mm, 6.3mm, 6.5mm, 6.6mm, or 6.8mm, or any value between two of them.
[0182] In some embodiments, please refer to Figure 2 The interior of the second functional section 142 has a first air intake passage 1421 extending in a first direction.
[0183] The interior of the second functional section 142 forms a first air intake channel 1421, which is beneficial for the aerosol generated by heating the aerosol product 10 to first flow through the first air intake channel 1421 for cooling. After passing through the first air intake channel 1421, the aerosol then flows through the filter section, where the filter section filters the aerosol.
[0184] For example, the volume of the first air intake passage 1421 is greater than or equal to 37 mm². 3 .
[0185] Here, the volume of the first air intake passage 1421 is set to be greater than or equal to 37 mm. 3 This allows the volume of the first air intake channel 1421 to be appropriate, improving the problem of high suction resistance, high interception, and low smoke volume of aerosol-generated product 10 caused by the small volume of the first air intake channel 1421.
[0186] For example, the wall thickness of the first air intake passage 1421 ranges from 0.05 mm to 2.9 mm.
[0187] The wall thickness of the first air intake passage 1421 can be any one of 0.05mm, 0.1mm, 0.2mm, 0.5mm, 1mm, 1.1mm, 1.3mm, 1.5mm, 1.8mm, 1.9mm, 2mm, 2.3mm, 2.5mm, 2.6mm, 2.8mm, or 2.9mm, or a value between any two.
[0188] Here, when the wall thickness of the first air intake channel 1421 is less than 0.05mm, the cooling support section has poor support effect and is prone to deformation. When the wall thickness of the first air intake channel 1421 is greater than 2.9mm, the aerosol extraction channel 123 is too narrow, which affects the amount of smoke generated by the aerosol product 10 and increases the suction resistance of the aerosol product 10.
[0189] In this embodiment, by setting the wall thickness of the first air inlet channel 1421 to 0.05mm-2.9mm, the cooling support section can have a certain support effect, while also having appropriate suction resistance, which is conducive to the extraction of aerosols and the aerosol-generated product 10 can have a certain amount of smoke.
[0190] In some embodiments, please refer to Figure 2The second functional section 142 has a second air intake channel 1422 that passes through the side wall of the first air intake channel 1421, and the first air intake channel 1421 is connected to the outside of the functional section 14 through the second air intake channel 1422.
[0191] Here, the second functional section 142 forms a second air intake channel 1422 that passes through the side wall of the first air intake channel 1421. That is, the second air intake channel 1422 passes through the side wall of the first air intake channel 1421 and is connected to the first air intake channel 1421.
[0192] For example, the wrapping layer 13 has a through hole at the position corresponding to the second air intake channel 1422 to avoid the second air intake channel 1422.
[0193] In this embodiment, the first air intake channel 1421 is connected to the outside of the functional section 14 through the second air intake channel 1422. External air can enter the first air intake channel 1421 through the second air intake channel 1422, which is beneficial to cooling the aerosol in the first air intake channel 1421, thereby further improving the cooling effect of the cooling section.
[0194] By adding a lateral air intake channel 123 (i.e., the second air intake channel 1422), the internal and external environmental pressure of the airflow circulation is adjusted, which helps to improve the problem of slow aerosol extraction efficiency in the front section of the bottom air intake aerosol generation device 20 under the circumferential heating mode, reduces the transmission temperature of the extracted aerosol, and adjusts the suction resistance (RTD) of the aerosol generation system 100.
[0195] In some embodiments, please refer to Figures 1 to 3 The distance between the second air intake passage 1422 and the distal lip of the front plug section 12 is 26mm-52mm.
[0196] The distance between the second intake passage 1422 and the distal lip of the front plug section 12 can be any one of 26mm, 27mm, 30mm, 32mm, 33mm, 35mm, 38mm, 40mm, 42mm, 43mm, 45mm, 48mm, 50mm, or 52mm, or any value between two of them.
[0197] With a fixed length for the aerosol generating product 10 and the functional section 14, when the distance between the second air intake channel 1422 and the distal lip of the front plug section 12 is greater than 52 mm, the mixing area provided by the incoming outside air is small, which is not conducive to the expression of aerosol aroma. When the distance between the second air intake channel 1422 and the distal lip of the front plug section 12 is less than 26 mm, the aerosol is easily mixed with the outside air in advance, leading to condensation, throttling, and a decrease in transmission efficiency during the transmission process. In other words, by making the distance between the second air intake channel 1422 and the distal lip of the front plug section 12 less than or equal to 52 mm, it is beneficial for the air entering from the second air intake channel 1422 to be fully mixed with the aerosol in the first air intake channel 1421, thereby improving the cooling effect of the cooling section. Setting the distance between the second air intake channel 1422 and the distal lip of the front plug section 12 to be greater than or equal to 26 mm is beneficial for improving the transmission efficiency of the aerosol and mitigating condensation during the transmission process.
[0198] Preferably, the distance between the second air intake passage 1422 and the distal lip of the front plug section 12 is 27mm-46mm.
[0199] For example, the cross-sectional shape of the second air intake passage 1422 includes at least one of circular, elliptical, and polygonal shapes.
[0200] In some embodiments, please refer to Figures 1 to 3 The functional segment 14 and the aerosol generating product 10 are cylindrical and coaxially arranged, with the first direction being the axial direction of the functional segment 14 and the aerosol generating product 10.
[0201] By setting both the functional segment 14 and the aerosol generating article 10 as cylinders and arranging them sequentially along the axial direction of the functional segment 14 and the aerosol generating article 10, the structure of the aerosol generating article 10 can be made more compact, improving the user experience.
