Description

Technical Field

[0001] This application relates to the field of heated non-combustible aerosol generation technology, and in particular to an aerosol generation product, an aerosol generation system, and a plug. Background Technology

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material can be tobacco or other non-tobacco products, which may or may not contain nicotine. Known tobacco or other non-tobacco products employ a plug at the upstream end to prevent the tobacco or non-tobacco material from falling out or detaching from the upstream end; the plug is typically made of a porous polymer such as cellulose acetate or polyethylene, allowing a heater to pass through the plug and be inserted into the tobacco or non-tobacco material for heating. In known tobacco or other non-tobacco products, the plug is a porous synthetic polymer material such as cellulose acetate or polyethylene; in the manufacturing process, these synthetic polymer materials are foamed or towed and then wrapped together with tobacco in cigarette paper to form a cigarette. The plug provides support at the upstream end of the tobacco material to prevent the tobacco material from falling out from the upstream end before or after use. Utility Model Content

[0046] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0047] One embodiment of this application proposes a heated aerosol generating article comprising multiple elements assembled in the form of strips, capable of generating aerosols when heated.

[0048] For example Figure 1 This is a schematic diagram of an aerosol-generating article 1000 according to one embodiment. Figure 1 As shown, the aerosol generating article 1000 includes an upstream end 1100 and a downstream end 1200 facing away from each other; as used herein, the terms 'upstream' and 'downstream' are used to describe the relative positions of elements or portions of elements of the aerosol generating article 1000 with respect to the direction in which a user draws air from the aerosol generating article 1000 during its use. Downstream can be a direction closer to the user's drawing direction, while upstream is correspondingly a direction away from the user; and, the upstream direction can be the direction in which external air enters the aerosol generating article 1000, and the downstream direction can be the direction in which an airflow containing aerosol exits from the aerosol generating article 1000, for example... Figure 1 The direction is indicated by the middle arrow R12. During use, the aerosol generated by heating within the aerosol generating article 1000 passes through the downstream end 1200 and exits from the downstream end 1200 before being delivered to the user. During use, the user can suction from the downstream end 1200 to inhale the aerosol.

[0049] Among them Figure 1 In the illustrated embodiment, for ease of use by typical users, the aerosol generating article 1000 has an overall elongated cylindrical structure. Alternatively, in some other variations, the aerosol generating article 1000 may be an elongated elliptical cylinder, a square prism, a polygonal prism, etc.

[0050] The aerosol generating article 1000 can mimic the appearance of a conventional, lit, and smokeable cigarette. The aerosol generating article 1000 can have an outer diameter between approximately 5 mm and 12 mm (e.g., between approximately 5 mm and 10 mm). The aerosol generating article 1000 has an overall length between approximately 40 and 100 mm; in an optional embodiment, the aerosol generating article 1000 has an overall length between approximately 45 and 55 mm.

[0051] according to Figure 1 As shown, the aerosol generating article 1000 includes multiple components arranged coaxially from the upstream end 1100 to the downstream end 1200:

[0052] The aerosol generating matrix 1130, cooling element 1120, and filter element 1110 are arranged sequentially and constrained by an external enclosure 1160 to form an aerosol generating article 1000. Wherein:

[0053] The components include a plug 1140, an aerosol generating matrix 1130, a cooling element 1120, and a filter element 1110. These components are arranged sequentially and constrained by an external enclosure 1160 to form an aerosol generating article 1000.

[0054] In one embodiment, the plug 1140 is located upstream of the aerosol generating matrix 1130. In another embodiment, the plug 1140 is close to and defines the upstream end 1100, thereby preventing material from the aerosol generating matrix 1130 or the generated aerosol / aerosol condensate from flowing out of the upstream end 1100. In some examples, the plug 1140 is immediately upstream of the aerosol generating matrix 1130. In another embodiment, the plug 1140 is airflow-permeable, allowing air to enter from the upstream end 1100 during suction and flow through the plug 1140 to the downstream aerosol generating matrix 1130.

[0055] Aerosol generating matrix 1130 describes a matrix capable of releasing volatile compounds upon heating, which can form aerosols. Aerosols described herein can be visible or invisible and can comprise vapors (e.g., fine particles of matter in a gaseous state, which are typically liquid or solid at room temperature) as well as droplets of gas and condensed vapors. Aerosol generating matrix 1130 can comprise one or more of the following: powders, granules, pellets, fragments, strands, strips, or sheets, comprising one or more of the following: dried flowers or leaves, grass leaves, tobacco leaves, tobacco midribs, expanded tobacco, and homogenized tobacco. In an alternative embodiment, aerosol generating matrix 1130 comprises aggregated sheets of wrinkled homogenized tobacco material confined by an outer wrapper 1160; the aggregated sheets of wrinkled homogenized tobacco material comprise glycerol as an aerosol forming agent.

[0056] The cooling element 1120 can be arranged immediately downstream of and adjacent to the aerosol generating matrix 1130. The cooling element 1120 serves two purposes: firstly, to provide downstream support for the aerosol generating matrix 1130; secondly, during use, volatile substances released from the heated aerosol generating matrix 1130 pass downstream of the aerosol generating article 1000 along the cooling element 1120, and these volatile substances can be cooled within the cooling element 1120 to form an aerosol inhaled by the user. Figure 1 In an alternative embodiment shown, the cooling element 1120 includes a cooling cavity 1121 extending along the length of the cooling element 1120. The axially extending cooling cavity 1121 ensures that the airflow through the cooling element 1120 is longitudinally directed without significant radial deviation. The cooling element 1120 can cool the temperature of the aerosol stream drawn through it by means of heat transfer. The components of the aerosol will interact with the space within the cooling element 1120 and lose thermal energy. The cooling element 1120 may comprise ceramic, metal, or organic polymer plastic, etc. In some embodiments, the temperature of the aerosol stream may decrease by more than 10 degrees Celsius as it is drawn through the cooling element 1120. In some embodiments, the temperature of the aerosol stream may decrease by more than 25 degrees Celsius or more than 30 degrees Celsius as it is drawn through the cooling element 1120.

[0057] Filter element 1110 is arranged immediately downstream of cooling element 1120 and defines downstream end 1200, and is adjacent to cooling element 1120 for filtering aerosols before delivery to the user. Figure 1 In the embodiments shown, the filter element 1110 comprises a conventional cellulose acetate or polypropylene tow filter core with low filtration efficiency.

[0058] Alternatively, in some other embodiments, the aerosol generating article 1000 may not include the cooling element 1120, and a cooling effect may be achieved by making the filter element 1110 longer, thereby providing heat exchange during the downstream delivery of the aerosol.

[0059] Alternatively, in some further variations, the aerosol generating article 1000 may also include:

[0060] A support element, located between the cooling element 1120 and the aerosol generating matrix 1130, is provided downstream of the aerosol generating matrix 1130 to prevent the aerosol generating matrix 1130 from moving downstream or material debris of the aerosol generating matrix 1130 from entering the cooling element 1120 downstream.

[0061] In some embodiments, the support element may be made of rigid ceramic, organic polymer or other materials; wherein the organic polymer may include one or more of cellulose acetate, polypropylene fiber, PET fiber, silicone, polylactic acid, PBAT; for example, in some specific embodiments, the support element is airflow-permeable cellulose acetate, which provides support for the aerosol generation matrix 1130 downstream while also allowing aerosols to pass through.

[0062] In some embodiments, the support element may be annular in shape. In some embodiments, the inner diameter of the support element is greater than or equal to the inner diameter of the cooling cavity 1121.

[0063] To assemble the aerosol-generating article 1000, the multiple components described above are aligned and tightly enclosed within the outer enclosure 1160. Figure 1 In the embodiments shown, the outer wrapping 1160 may be at least one of conventional cigarette paper, cellulose paper, metal foil, metal foil composite cellulose paper, polyethylene composite cellulose paper, etc.

[0064] In some embodiments, the thickness of the outer wrapping 1160 is 0.08–0.3 mm; more preferably, the thickness of the outer wrapping 1160 is 0.35–0.45 mm. In some embodiments, the basis weight or areal density of the outer wrapping 1160 of the cigarette paper roll is 70–200 g / m³. 2 Among them, "quantity" is a term in the cigarette industry, referring to the mass per unit area of ​​thin or sheet-like materials; "quantity" has the same meaning as the material science term "area density".

[0065] In some embodiments, the aerosol generating article 1000 is further provided with:

[0066] One or more cooling communication holes extend from the outer surface of the aerosol generating article 1000 to the cooling chamber 1121 along the radial direction of the aerosol generating article 1000, for allowing external cold air to enter the cooling chamber 1121 to promote aerosol condensation. In some embodiments, the cooling communication holes are formed by laser drilling.

[0067] In some embodiments, the plug 1140 is airflow-permeable, thereby allowing air to pass through the plug 1140 during suction and be delivered to the downstream aerosol-generating matrix 1130.

[0068] according to Figures 1 to 3 As shown, the plug 1140 includes:

[0069] The basic sheet-like stop portion 1142, and the tubular extension portion 1141 extending from the stop portion 1142 away from the aerosol generating matrix 1130. Figures 1 to 3In the embodiment shown, the extension 1141 and the stop 1142 of the plug 1140 are substantially circular in shape.

[0070] In some embodiments, the sheet-like stop 1142 and the tubular extension 1141 of the plug 1140 are integrally formed. For example, in some embodiments, the plug 1140 is formed by stamping a sheet-like substrate in a die; during the stamping process, the sheet-like stop 1142 is formed by the portion of the substrate that is contacted and pressed by the stamping head of the die, and the extension 1141 is formed by the edge that avoids the stamping head of the die after being stretched during stamping. The sheet-like substrate has a predetermined shape and size.

[0071] In some embodiments, the plug 1140, having a sheet-like stop 1142 and a tubular extension 1141, is made from a sheet-like substrate that can be stamped or stretched. For example, in some specific embodiments, the plug 1140 may be made from one or more of cellulose paper, metal foil, metal foil composite cellulose paper, ceramic film, modified polypropylene film, modified polylactic acid film, PET composite cellulose paper, and cellulose acetate paper.

[0072] Alternatively, in some other embodiments, the sheet-like stop 1142 and the plug 1140 of the tubular extension 1141 are integrally molded.

[0073] In some embodiments, the thickness of the sheet-like stop portion 1142 and / or the wall thickness of the tubular extension portion 1141 are approximately between 0.01 and 0.15 mm. In some embodiments, the basis weight of the sheet-like stop portion 1142 and / or the tubular extension portion 1141 is 10 to 60 g / m³. 2 .

[0074] In some embodiments, the thickness and / or hardness and / or density and / or tensile strength of the outer wrapping 1160 is greater than the thickness and / or hardness and / or density and / or tensile strength of the tubular extension 1141.

[0075] In one embodiment, the sheet-like stop 1142 is arranged perpendicular to the axial direction of the aerosol generating article 1000. The stop 1142 longitudinally abuts against the aerosol generating matrix 1130, thereby providing a barrier to the aerosol generating matrix 1130. In another embodiment, the stop 1142 is pierced by the heater 30 of the heating device. In some embodiments, the stop 1142 is easily broken or fractured.

[0076] exist Figures 1 to 2 As shown, the extension 1141 extends from the stop 1142 toward the upstream end 1100 and terminates at the upstream end 1100.

[0077] In some embodiments, the extension 1141 may have a length between approximately 2 mm and 5 mm. In some embodiments, the plug 1140 has a length of less than 5 mm.

[0078] In some embodiments, the tubular extension 1141 of the plug 1140 is securely bonded to the outer wrapping 1160 with an adhesive, thereby firmly attaching the plug 1140 to the outer wrapping 1160 and preventing the plug 1140 from separating from or falling out of the outer wrapping 1160. In some specific embodiments, during the preparation of the aerosol generating article 1000, the tubular extension 1141 of the plug 1140 is bonded to the outer wrapping 1160 with an adhesive such as water-based acrylic adhesive, high-temperature resistant silicone, modified epoxy resin, polyurethane hot melt adhesive, or ceramic-based high-temperature resistant adhesive, thereby securely bonding the plug 1140 to the outer wrapping 1160. In embodiments, the adhesive is heat-resistant or thermally stable to prevent decomposition during the heating and use of the aerosol generating article 1000.

[0079] according to Figures 1 to 3 As shown, at least one or more air holes 1144 are arranged on the stop portion 1142 to provide air through the stop portion 1142 into the aerosol generating matrix 1130, thereby allowing airflow through the stop portion 1142.

[0080] In some embodiments, the area of ​​the pores 1144 is 0.7 μm. 2 ~0.2mm 2 Alternatively, in some embodiments, the hydraulic diameter of the pore 1144 is 0.001 to 0.5 mm.

[0081] exist Figures 1 to 3 In the embodiment shown, the plug 1140 further defines:

[0082] The temperature drop chamber 1143 is defined by a tubular extension 1141; and the temperature drop chamber 1143 is located between the stop portion 1142 and the upstream end 1100. The temperature drop chamber 1143 is open at the upstream end 1100.

[0083] Figure 12 The diagram shows a schematic of an aerosol generation system comprising an aerosol generation product 1000 and a heating device; in use, according to... Figure 12 As shown, the aerosol generating article 1000 is received in a heating device, and the aerosol generating matrix 1130 of the aerosol generating article 1000 is heated by the heating device to generate aerosol. According to Figure 12 In the illustrated embodiment, the heating device includes:

[0084] The chamber has an opening 40; in use, the aerosol-generating article 1000 can be removably received in the chamber through the opening 40.

[0085] A heater 30, which extends at least partially within the chamber, is inserted into the aerosol generating matrix 1130 of the aerosol generating article 1000 when the aerosol generating article 1000 is received in the chamber, and heats the aerosol generating article 1000 to release a variety of volatile compounds, which are formed solely by heat treatment.

[0086] Cell 10 is used for power supply;

[0087] Circuit 20 is used to guide current between cell 10 and heater 30.

[0088] In one embodiment, the heater 30 generates an aerosol that can be inhaled by heating the aerosol generating matrix 1130 to a temperature above the minimum heating temperature required to generate the aerosol.

[0089] exist Figure 12 In the illustrated embodiment, the heater 30 is generally shaped like a pin, needle, rod, column, sheet, or plate. When the aerosol generating article 1000 is received in the chamber, the heater 30 is inserted into the aerosol generating matrix 1130 from the upstream end 1100 of the aerosol generating article 1000 through the cooling chamber 1143 to heat and generate aerosol. In some embodiments, the heater 30 may have a length of approximately 10 to 18 mm and an outer diameter of approximately 2 to 4 mm.

[0090] In this embodiment, when the aerosol-generating article 1000 is received in the heating device, the heater 30 extends into the aerosol-generating matrix 1130. In use, the aerosol-generating matrix 1130 is heated to generate aerosols, which are then output downstream.

[0091] In some embodiments, the heater 30 may also be configured to at least partially surround or define a chamber arrangement; for example, the heater 30 may be configured as a tubular shape that at least partially surrounds the chamber. When the aerosol generating article 1000 is received in the chamber, the heater 30 at least partially surrounds or encloses the aerosol generating article 1000 and heats it from the outer periphery of the aerosol generating article 1000. Furthermore, when the aerosol generating article 1000 is received within a heating device, it is at least partially contained and held within the heater 30, and is then heated from the outside around the aerosol generating matrix 1130 of the aerosol generating article 1000 by the heater 30, thereby causing the aerosol generating article 1000 to release a variety of volatile compounds, which are formed solely by heat treatment. In some embodiments, the tubular heater 30 may have an inner diameter of approximately 5.8 mm to 10 mm.

[0092] In some embodiments, heater 30 includes at least one of a resistance heater, induction heater, infrared heater, microwave heater, or light heater such as a laser heater.

[0093] according to Figure 12 As shown, when the aerosol-generating article 1000 is received in a heating device for heating, the heater 30 of the heating device is inserted into the aerosol-generating matrix 1130 from the upstream end 1100 through the cooling chamber 1143 for heating. And according to... Figure 12 As shown, during use, when the heater 30 passes through the cooling chamber 1143 of the plug 1140 to heat the aerosol generating matrix 1130, at least a portion of the surface of the heater 30 is exposed within the cooling chamber 1143, and a gap exists between the heater 30 and the inner surface of the cooling chamber 1143. In one aspect, the cooling chamber 1143 is configured to reduce the temperature of the heater 30 surrounding it, such that the contact temperature between the heater 30 and the plug 1140 can be reduced to below 200°C, or to a temperature range that the plug 1140 can withstand, thereby preventing the plug 1140 from being burned by the high temperature of the heater 30. In another aspect, the cooling chamber 1143 also provides a preheating space for air to pass through the heater 30 and enter the aerosol generation matrix 1130 in the axial direction. During suction, when cold air enters the cooling chamber 1143, it can absorb some of the heat from the heater 30 in the cooling chamber 1143 to form hot air. Then, the hot air enters the aerosol generation matrix 1130, which can prevent a sudden drop in temperature inside the aerosol generation matrix 1130 due to suction. At the same time, when cold air enters the cooling chamber 1143, it can accelerate the heat loss from the surface of the heater 30 in the cooling chamber 1143, thereby significantly increasing the temperature gradient on the heater 30.

[0094] During use, the stop portion 1142 of the plug 1140 supports the aerosol generating matrix 1130 upstream, which can prevent the aerosol generating matrix 1130 from falling out due to shaking of the aerosol generating product 1000 during transportation and use, thereby improving the structural stability of the aerosol generating product 1000.

[0095] Figures 4 to 5 A schematic diagram of another embodiment of an aerosol-generating article 1000a is shown; in this embodiment, the aerosol-generating article 1000a includes a plurality of elements enclosed and confined by an outer enclosure 1160a; the plurality of elements include those arranged coaxially from an upstream end 1100a to a downstream end 1200a.

[0096] The plug 1140a, the aerosol generating matrix 1130a, the cooling element 1120a, and the filter element 1110a.

[0097] exist Figure 4 and Figure 5 In the illustrated embodiment, the plug 1140a includes a sheet-like stop 1142a and a tubular extension 1141a. A cooling chamber 1143a is surrounded and defined within the tubular extension 1141a. The tubular extension 1141a is tapered. Specifically, the inner diameter D1 and / or outer diameter of the tubular extension gradually decreases in the direction approaching the stop 1142a. In this embodiment, the tubular extension 1141a is inclined. After assembly, a gap 1145a exists between the tubular extension 1141a and the outer cover 1160a.

[0098] or Figure 6 A schematic diagram of another embodiment of the plug 1140b is shown, in which the plug 1140b includes a sheet-like stop portion 1142b and a tubular extension portion 1141b. The extension portion 1141b includes a first segment 11411b and a second segment 11412b arranged sequentially; the first segment 11411b is closer to the upstream end; the outer diameter of the first segment 11411b is larger than the outer diameter of the second segment 11412b. After being assembled into the outer wrapping component 1160, a gap can be formed between the second segment 11412b and the outer wrapping component 1160.

[0099] or Figure 7 A schematic diagram of a plug 1140c according to another embodiment is shown, in which the outer surface of the tubular extension 1141c is serrated or has an alternating convex and concave shape. A plurality of circumferentially spaced protrusions 1146c are arranged on the outer surface of the tubular extension 1141c. After the plug 1140c is fitted into the outer cover 1160, the protrusions 1146c abut against the outer cover 1160, forming a plurality of air channels between the outer cover 1160 and the plug 1140c, each air channel being located between adjacent protrusions 1146c. In this embodiment, the air channels extend axially through the plug 1140c. Furthermore, the air channels defined between adjacent protrusions 1146c extend in a straight line.

[0100] or Figure 8 A schematic diagram of a plug 1140d according to another embodiment is shown, in which the outer surface of the tubular extension 1141d is polygonal columnar. After the plug 1140d is assembled inside the outer cover 1160, a plurality of circumferentially spaced air channels can be formed between the outer cover 1160 and the outer surface of the plug 1140d.

[0101] Figures 9 to 10A schematic diagram of another embodiment of an aerosol-generating article 1000e is shown; in this embodiment, the aerosol-generating article 1000e includes a plurality of elements enclosed and confined by an outer enclosure 1160e; the plurality of elements include those arranged coaxially from an upstream end 1100e to a downstream end 1200e:

[0102] The plug 1140e, the aerosol generating matrix 1130e, the cooling element 1120e, and the filter element 1110e.

[0103] exist Figure 9 and Figure 10 In the illustrated embodiment, the plug 1140e includes a sheet-like stop portion 1142e and a tubular extension portion 1141e. A temperature cooling cavity 1143e is surrounded and defined within the tubular extension portion 1141e.

[0104] according to Figure 9 and Figure 10 As shown, the plug 1140e also includes:

[0105] The bend 1147e bends from the tubular extension 1141e to form or define the outer wrapping 1160e; the bend 1147e surrounds and is attached to the outer surface of the outer wrapping 1160e.

[0106] In some embodiments, the length of the bend 1147e is less than the length of the extension 1141e. In some embodiments, the length of the bend 1147e is approximately between 1 and 2 mm.

[0107] In some embodiments, the bend 1147e is defined by bending the excess length of the tubular extension 1141e. For example Figure 11 A schematic diagram is shown of the fabrication process in which an elongated plug is wrapped around or mounted outside an outer cover 1160e; in this embodiment, the tubular extension 1141e of the plug has an elongated portion 1147f extending beyond the outer cover 1160e; and then the elongated portion 1147f is... Figure 11 The extension 1147f is bent as indicated by the middle arrow P11, so that it surrounds and attaches to the outer surface of the outer wrapping 1160e to form a bend.
