Description

Technical Field

[0001] This application relates to the field of aerosol-generating articles, and in particular to aerosol-generating articles. Background Technology

[0002] In related technologies, the aerosol-generating matrix in heated tobacco products is typically filled with tobacco flakes or shredded tobacco. This matrix is ​​generally loose and has low thermal conductivity. When heating the aerosol-generating matrix using circumferential heating, the e-cigarette requires a high energy output, resulting in a relatively slow heating rate and long preheating time. Once smoke is generated, the air intake is low, leading to higher inhaled smoke temperatures and negatively impacting the user's vaping experience. Furthermore, thermal expansion and contraction, along with airflow impact, can easily cause the flakes or tobacco fragments to detach. These detached particles can easily enter the e-cigarette device, making cleaning difficult and posing challenges for users' maintenance. Utility Model Content

[0003] Therefore, it is necessary to provide an aerosol generating product to address the problems of slow heating rate of aerosol generating matrix, high temperature of smoke inhaled by users, and the difficulty in cleaning up particulate matter detached from aerosol generating matrix that easily enters the interior of electronic cigarettes.

[0004] An aerosol-generating article, comprising:

[0005] The aerosol generating matrix has a cavity that extends through the aerosol generating matrix along a first direction. The wall thickness of the aerosol generating matrix is ​​less than the minimum cross-sectional dimension of the cavity along the first direction. The cavity has an air inlet and an air outlet at its two ends along the first direction. The end of the aerosol generating matrix near the air inlet has a first end face. The aerosol generating matrix is ​​a solid integrally formed.

[0006] Edge banding, the edge banding abuts against the first end face;

[0007] The filter element is located downstream of the aerosol generating matrix.

[0008] In one embodiment, the inner surface of the cavity is provided with grooves and / or protrusions.

[0009] In one embodiment, the edge banding includes:

[0010] The enclosure section is located around the entire periphery of the aerosol generating matrix, or the enclosure section is located around the periphery of one end of the aerosol generating matrix that has an air inlet.

[0011] The edge sealing section has one end connected to one end of the enclosure section, and the edge sealing section abuts against the first end face.

[0012] In one embodiment, the edge banding also includes:

[0013] The inner extension section has a connecting end and a free end. The connecting end is connected to the other end of the sealing section, and the free end extends into the cavity.

[0014] In one embodiment, the inner extension section is inclined, the connecting end is connected to the sealing section, and the free end is located on the side of the connecting end near the center of the cavity.

[0015] In one embodiment, the aerosol generating matrix has a second end face at the end near the outlet, and the aerosol generating article further includes:

[0016] The support is disposed on one side of the second end face of the aerosol generating matrix. The support has a mixing chamber, one end of which is connected to the cavity, and the other end of which has an opening.

[0017] One end of the filter element abuts against one end of the support element, and the filter element covers the opening.

[0018] In one embodiment, the support is a hollow tubular structure.

[0019] In one embodiment, the aerosol-generating article further includes:

[0020] The outer casing surrounds the aerosol generating matrix, support, and filter.

[0021] In one embodiment, the aerosol-generating article further includes:

[0022] Cooling holes are provided, which penetrate the outer casing and the support component, and are connected to the mixing chamber.

[0023] In one embodiment, the support is made of paper and the edge banding is made of metal.

[0024] The aforementioned aerosol generating product features an aerosol generating matrix with a through-cavity, including an air inlet and an air outlet. A sealing element abuts against the first end face of the aerosol generating matrix, and a filter element is positioned downstream of the aerosol generating matrix. This configuration increases the heated surface area and reduces the heated volume of the aerosol generating matrix, allowing heat to be rapidly transferred to its interior, thereby improving heating efficiency and reducing energy consumption. Furthermore, external cool air can flow into the cavity through the air inlet and mix with the vapor released from the aerosol generating matrix, lowering the vapor temperature and effectively reducing the temperature of the inhaled vapor, thus enhancing the user's vaping experience. Simultaneously, the sealing element can receive and contain particles detached from the aerosol generating matrix, preventing them from falling into the e-cigarette and reducing the user's cleaning and maintenance burden, further improving the user experience. Furthermore, the wall thickness of the aerosol generating matrix is ​​less than the minimum cross-sectional dimension of the cavity along the first direction, which reduces the heat conduction path of the aerosol generating matrix and thus further improves heat conduction efficiency. Simultaneously, the smaller wall thickness of the aerosol generating matrix improves the uniformity of heating, ensuring its normal operation. Moreover, the larger cavity reduces airflow resistance, providing sufficient airflow for the high-temperature flue gas, facilitating temperature reduction, and making the user's inhalation process smoother, reducing suction resistance. The filter element can filter out fine particles and some condensate droplets in the flue gas, further improving the user experience. Additionally, the aerosol generating matrix is ​​a one-piece solid, facilitating the machining of cavities within it and reducing manufacturing complexity. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0057] See Figures 1 to 3 as well as Figure 12 This application provides an embodiment of an aerosol generating article, comprising an aerosol generating matrix 10, a sealing element 20, and a filter element 40. The aerosol generating matrix 10 has a cavity 11 extending through it along a first direction. The wall thickness t of the aerosol generating matrix 10 is less than the minimum cross-sectional dimension D of the cavity 11 along the first direction. The cavity 11 has an inlet 111 and an outlet 112 at its two ends along the first direction, respectively. The aerosol generating matrix 10 has a first end face 12 near the inlet 111. The aerosol generating matrix 10 is a monolithically formed solid. The sealing element 20 abuts against the first end face 12 and is used to receive detached material from the aerosol generating matrix 10. The filter element 40 is disposed downstream of the aerosol generating matrix 10. (See also...) Figure 1 The X direction is the first direction.

[0058] Applying the technical solution of this application, the aerosol generating matrix 10 has a through-hole 11, and the cavity 11 has an air inlet 111 and an air outlet 112. The sealing member 20 abuts against the first end face 12 of the aerosol generating matrix 10, and the filter member 40 is disposed downstream of the aerosol generating matrix 10. This configuration increases the heated area of ​​the aerosol generating matrix 10 and reduces its heated volume, allowing heat to be quickly transferred to the interior of the aerosol generating matrix 10, thereby improving the heating efficiency of the aerosol generating matrix 10 and reducing energy consumption. Furthermore, external cold air can flow from the air inlet 111 into the cavity 11 and mix with the flue gas released from the aerosol generating matrix 10, thereby reducing the flue gas temperature and effectively lowering the temperature of the flue gas inhaled by the user, improving the user's inhalation experience. Meanwhile, the edge sealing component 20 can receive and contain particles detached from the aerosol generating matrix 10, preventing them from falling into the e-cigarette and reducing the user's cleaning and maintenance burden, thus improving the user experience. Furthermore, the wall thickness of the aerosol generating matrix is ​​less than the minimum cross-sectional dimension of the cavity along the first direction, reducing the heat conduction path of the aerosol generating matrix 10 and further improving heat conduction efficiency. Simultaneously, the smaller wall thickness of the aerosol generating matrix 10 improves the uniformity of heating, ensuring its normal operation. Moreover, the larger cavity 11 reduces airflow resistance, providing sufficient airflow for the higher-temperature smoke, facilitating temperature reduction and making the inhalation process smoother, reducing the user's suction resistance. The filter component 40 can filter out small particles and some condensate droplets in the smoke, further improving the user experience. Additionally, the aerosol generating matrix 10 is a one-piece solid, facilitating the machining of cavities within it and reducing manufacturing difficulty.

[0059] In some embodiments, the aerosol generation matrix 10 can be formed by dry pressing or extrusion.

[0060] In some embodiments, the aerosol generating matrix 10 is a solid or integrally molded tobacco extract product, or the aerosol generating matrix 10 is a nicotine-containing composition.

[0061] See Figure 3 The inner surface of the cavity 11 is provided with grooves 113 and / or protrusions 114. This arrangement can increase the surface area of ​​the cavity 11 and further improve the flue gas release efficiency.

[0062] In some embodiments, the inner surface of the cavity 11 is provided with a plurality of grooves 113 and a plurality of protrusions 114, and the cross-sections of the grooves 113 and protrusions 114 can be of any structure.

[0063] See Figure 3In one embodiment, the groove 113 has a semi-circular structure and the protrusion 114 has an arc-shaped structure.

[0064] See Figure 4 In another embodiment, the groove 113 is a planar structure and the protrusion 114 is a conical structure.

[0065] See Figure 5 In another embodiment, both the groove 113 and the protrusion 114 are arc-shaped structures.

[0066] See Figure 6 and Figure 7 In one embodiment, the edge sealing member 20 includes a surrounding section 21 and an edge sealing section 22. The surrounding section 21 surrounds the outer periphery of the aerosol generating matrix 10. One end of the edge sealing section 22 is connected to one end of the surrounding section 21, and the edge sealing section 22 abuts against the first end face 12. The edge sealing section 22 is used to receive detached material from the aerosol generating matrix 10.

[0067] In some embodiments, the enclosure section 21 encloses the entire periphery of the aerosol generating matrix 10.

[0068] In other embodiments, the enclosure section 21 is disposed around the outer periphery of the end of the aerosol generating matrix 10 having the air inlet 111. That is, the enclosure section 21 may only wrap around the outer periphery of the aerosol generating matrix 10 near the air inlet 111, for example, the outer periphery of the first half of the aerosol generating matrix 10 near the air inlet 111.

[0069] See Figures 8 to 11 In another embodiment, the edge-sealing member 20 includes a surrounding section 21, an edge-sealing section 22, and an inner extension section 23. The surrounding section 21 surrounds the outer periphery of the aerosol generating matrix 10. One end of the edge-sealing section 22 is connected to one end of the surrounding section 21, and the edge-sealing section 22 abuts against the first end face 12. The inner extension section 23 has a connecting end 231 and a free end 232. The connecting end 231 is connected to the other end of the edge-sealing section 22, and the free end 232 extends into the cavity 11. The edge-sealing section 22 and the inner extension section 23 are used to receive the detached material from the aerosol generating matrix 10. With this configuration, the surrounding section 21 surrounds the outer periphery of the aerosol generating matrix 10, which can cover the aerosol generating matrix 10, facilitating the subsequent assembly of the aerosol generating matrix 10 and reducing the possibility of the aerosol generating matrix 10 shedding residue. The edge-sealing section 22 directly abuts against the first end face 12, which can effectively receive the detached material from the first end face 12. The free end 232 of the inner extension 23 extends into the cavity 11, which can actively intercept and collect the components of the detached material that falls off the inner wall of the aerosol generation matrix 10. It can also collect and store condensate, further improving the effect of the sealing part 20 in receiving the detached material, thereby further preventing the detached material from falling into the electronic cigarette.

[0070] Among them, the aerosol generating matrix 10 shedding material includes aerosol generating matrix 10 debris and condensed flue gas, soot, etc.

[0071] See Figure 11 The inner extension section 23 is inclined, with the connecting end 231 connected to the sealing section 22, and the free end 232 located on the side of the connecting end 231 near the center of the cavity 11. This arrangement ensures that the receiving surface of the inner extension section 23 corresponds to the inner wall of the aerosol generating matrix 10, improving the efficiency of collecting detached materials. Furthermore, the inclined inner extension section 23 guides and concentrates the collected detached materials at the connection point between the inner extension section 23 and the sealing section 22, preventing the materials from scattering. Simultaneously, the inclined inner extension section 23 reduces its impact on airflow, avoiding disturbance to the airflow.

[0072] See Figure 12 and Figure 13 The aerosol generating matrix 10 has a second end face 13 at one end near the outlet 112. The aerosol generating article also includes a support member 30. The support member 30 is disposed on one side of the second end face 13 of the aerosol generating matrix 10. The support member 30 has a mixing chamber 31, one end of which communicates with the cavity 11, and the other end of which has an opening 311. One end of a filter member 40 abuts against one end of the support member 30, and the filter member 40 covers the opening 311. This arrangement provides axial support for the aerosol generating matrix 10, ensuring its stability. The mixing chamber 31 allows the flue gas flowing out of the cavity 11 to be mixed again and buffers the flow of the flue gas, ensuring thorough mixing of the flue gas and air within the mixing chamber 31, further homogenizing the flue gas temperature and concentration. The filter member 40, covering the opening 311 of the mixing chamber 31, can filter out small particles and some condensate droplets in the flue gas, improving the purity of the inhaled flue gas.

[0073] In some embodiments, the end of the support member 30 away from the filter member 40 abuts against the edge sealing member 20.

[0074] In other embodiments, the end of the support 30 away from the filter 40 abuts against the aerosol generating matrix 10.

[0075] Specifically, the support member 30 is a hollow tubular structure. This design facilitates the processing of the support member 30, while reducing its weight and ensuring its supporting effect.

[0076] See Figure 13 and Figure 14The aerosol generating product also includes an outer packaging 50, which surrounds the aerosol generating matrix 10, the support 30, and the filter 40. This arrangement allows the outer packaging 50 to encapsulate the aerosol generating matrix 10, the support 30, and the filter 40, while simultaneously protecting them from misalignment or damage during transportation or use.

[0077] See Figure 15 and Figure 16 The aerosol generating product also includes a cooling hole 60, which is disposed through the outer casing 50 and the support 30, and is connected to the mixing chamber 31. With this configuration, during suction, cold air can enter the mixing chamber 31 through the cooling hole 60 and mix with the higher temperature flue gas, further reducing the temperature of the suction gas.

[0078] In some embodiments, the aerosol-generating article includes two to nine cooling holes 60, which are uniformly distributed in the circumferential direction.

[0079] The support component 30 is made of paper, while the edge banding component 20 is made of metal. This design, using paper for the support component 30, reduces the cost of the aerosol-generated product and facilitates its processing, thus reducing the weight of the product. The edge banding component 20, made of metal, improves its thermal conductivity and moisture resistance.

[0080] In some embodiments, the edge banding 20 is made of aluminum foil, and aluminum has good ductility, making it easy to process aluminum into the edge banding 20.

[0081] In other embodiments, the edge banding 20 may be made of other metal materials with good ductility and thermal conductivity.

[0082] In some embodiments, the outer packaging 50 is a paper structure, specifically cigarette paper.

[0083] Another embodiment of this application provides an electronic cigarette device, including a heating chamber for heating the aforementioned aerosol-generating article. This configuration improves the inhalation effect of the electronic cigarette and enhances the user experience.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
