[0002] Heated cigarettes heat the tobacco's smoking section to produce smoke, resulting in a more palatable flavor. Currently, commercially available heated cigarettes mainly consist of a smoking section, a hollow support section, a cooling section, and a filter. The tobacco in the smoking section can be in the form of reconstituted tobacco sheets, shredded tobacco, granular tobacco, or blocky tobacco, either ordered or randomly filled. When the tobacco in the smoking section is heated, the flavorings and smoke-generating agents loaded on it evaporate, producing smoke.

[0003] Current heated tobacco products suffer from uneven smoke release and significant smoke attenuation during inhalation. Secondly, draw resistance is also a crucial factor for heated tobacco products; excessively low or high draw resistance can negatively impact the user experience. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0020] The following is a detailed description of a solid aerosol generation matrix, solid aerosol product, and solid aerosol generation system provided by embodiments of this utility model.

[0021] In this article, "far lip end" refers to the end of a heated tobacco product (cigarette) that is far from the user's lips when inhaled, while "near lip end" refers to the end of a heated tobacco product (cigarette) that is close to the user's lips when inhaled.

[0022] In a first aspect, embodiments of the present invention provide a solid aerosol generating matrix, including a tipping paper 200 and a columnar smoke-generating section body 100 located within the tipping paper 200. The smoke-generating section body 100 has a plurality of micropores 120 inside, and the plurality of micropores 120 are honeycomb-shaped in general. Each micropore 120 is evenly distributed within the smoke-generating section body 100 and is interconnected with each other.

[0023] The solid aerosol generating matrix structure provided by this invention ensures smooth aerosol passage while also helping to control the flow and density of smoke, thus providing a better smoking experience. This design not only improves the comfort of the product but also ensures uniform smoke distribution, making the smoking process more enjoyable. Furthermore, this structure helps improve product safety by rationally controlling aerosol output, reducing potential health risks to users.

[0024] It is worth noting that the aforementioned tobacco-generating segment body 100 is obtained through the following processing method: tobacco powder, powdered fiber, adhesive, smoking agent, foaming agent, and flavoring are mixed evenly, with the moisture content controlled between 10-20%. Then, it is molded using injection molding or extrusion, and finally dried using microwave to obtain the tobacco-generating segment body 100. The tobacco-generating segment body 100 prepared using the above method not only reduces the loss of aroma components in tobacco but also reduces subsequent processes such as reconstituted tobacco leaf rolling / shredding, thus reducing processing steps, lowering production costs, and resulting in higher product quality.

[0025] In an optional embodiment, the smoke-generating section body 100 is further provided with an air guiding channel 110. The air guiding channel 110 is distributed along the axial direction of the smoke-generating section body 100, and the micropores 120 are connected to the air guiding channel 110 to collect aerosols into the air guiding channel 110.

[0026] In an optional embodiment, the air guide channel 110 is located inside the smoke-generating section body 100. There is one or more air guide channels 110. The multiple air guide channels 110 are independent of each other or interconnected. The outer wall thickness of the air guide channel 110 is 0.4-1.8 mm, and the inner wall thickness is 0.2-1.2 mm.

[0027] In an optional embodiment, the air guide channel 110 is located outside the smoke-generating section body 100, and the gap between the serrations provided on the outside of the smoke-generating section body 100 and the splicing paper 200 constitutes the air guide channel 110.

[0028] In an optional embodiment, the smoke-generating section body 100 has a diameter of 6.0-7.3 mm, a length of 5-35 mm, and a porosity of 20-50%.

[0029] This utility model provides a solid aerosol generation matrix. After the solid aerosol generation matrix is ​​heated, the aerosol generated by heating enters the gas guiding channel 110 through the honeycomb-shaped micropores 120 and is collected. The gas guiding channel 110 has various forms. It can be set not only inside the smoke generating section body 100, but also outside the smoke generating section body 100. Different forms of setting can mix the aerosols generated at different positions of the smoke generating section body 100, making the aerosol uniformity better and bringing a continuous and stable aerosol suction performance.

[0030] Secondly, embodiments of this utility model also provide a solid aerosol product, including a tipping paper 200 and a filter component 300, a support component 400, a smoke generating component 500, and a functional component 600 arranged sequentially from the proximal lip end to the distal lip end within the tipping paper 200, wherein the smoke generating component 500 adopts the aforementioned solid aerosol generating matrix.

[0031] In an optional embodiment, the filter element 300 and the functional element 600 are made of cellulose acetate rods or paper rods.

[0032] In an optional embodiment, the length ratio of the support component 400 to the entire solid aerosol product is 0.5:1-0.8:1, and the length ratio of the smoke-generating component 500 to the functional component 600 is 0.3:1-0.6:1. This embodiment of the invention also provides a solid aerosol product in which the support component 400 is provided in both the filter component 300 and the smoke-generating component 500. The support component 400 can concentrate smoke and reduce the temperature of the smoke. At the same time, setting appropriate lengths for each component is beneficial for increasing the concentration of the aerosol. For example, a longer smoke-generating component 500 can produce a continuous and stable aerosol, prolonging the aerosol release time and increasing the user's satisfaction when inhaling the smoke.

[0033] In an optional embodiment, the suction resistance of the filter element 300 is greater than that of the functional element 600, which in turn is greater than that of the smoke-generating element 500, which is greater than that of the support element 400. When the suction resistance of each part of the solid aerosol product satisfies the above relationship, the aerosol generated by the heating of the smoke-generating element 500 can be filtered by the filter element 300 to retain most of the harmful substances, making the suction smoother.

[0034] This utility model also provides a solid aerosol product, including a tipping paper 200 and a filter component 300, a support component 400, a smoke-generating component 500, and a functional component 600 arranged sequentially from the proximal end to the distal end within the tipping paper 200. The filter component 300 and the functional component 600 are made of cellulose acetate rods or paper rods, specifically including the following four scenarios: both the filter component 300 and the functional component 600 are made of paper rods; both the filter component 300 and the functional component 600 are made of cellulose acetate rods; the filter component 300 is made of cellulose acetate rods and the functional component 600 is made of paper rods; and the filter component 300 is made of paper rods and the functional component 600 is made of cellulose acetate rods. When the functional component 600 at the distal end is made of paper rods, a flavoring substance can be added to the functional component 600. The flavoring substance includes, but is not limited to, popping beads, granules, slow-release gels, powders, pastes, and disordered materials. Furthermore, the functional component 600 can also be in the form of a flavoring stick formed from a porous material adsorbing flavoring material, or it can be a container that directly fills the functional material, as long as the functional material can be placed into the receiving cavity of the functional component 600. The purpose of the functional component 600 is to enhance the flavor of the aerosol and reduce harmful components in the aerosol while lowering the aerosol temperature.

[0035] The embodiment of this utility model also provides a solid aerosol product. After the functional component 600 performs one or more functions such as cooling, flavoring and filtering, the solid aerosol generating matrix of the smoke generating component 500 is heated. The aerosol generated by heating enters the air guiding channel 110 through the honeycomb micropores 120 and is collected. Then, most of the harmful substances in the aerosol are filtered out by the filter component 300 and finally enter the mouth of the smoker. The inhalation process is simpler and the user experience is improved.

[0036] Thirdly, embodiments of this utility model also provide a solid aerosol generation system, which includes an aerosol generation device and the aforementioned solid aerosol generation product. The aerosol generation device includes a heating element 700, which is used to heat the solid aerosol generation matrix to generate aerosols.

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Example 1

[0039] See Figure 1 , Figure 2 and Figure 3 This embodiment provides a solid aerosol generation matrix, including a tipping paper 200 and a columnar smoke-generating section body 100 located inside the tipping paper 200. The smoke-generating section body 100 has an internal air guiding channel 110 and a plurality of micropores 120. The plurality of micropores 120 are generally in a honeycomb structure. Each micropore 120 is evenly distributed in the smoke-generating section body 100 and is interconnected with each other. The air guiding channel 110 is distributed along the axial direction of the smoke-generating section body 100. The micropores 120 are connected to the air guiding channel 110 to collect aerosols into the air guiding channel 110.

[0040] See you again Figure 2 The air guide channel 110 is located inside the smoke-generating section body 100. There may be one or more air guide channels 110, and these channels are independent of each other. See again. Figure 3 Multiple air guide channels 110 are interconnected.

[0041] The smoke-generating section 100 has a diameter of 6.0-7.3 mm, a length of 5-35 mm, and a porosity of 20-50%. The measured smoke concentration is 52%.

[0042] Example 2

[0043] See Figure 1 and Figure 4 The structure of the solid aerosol generating matrix in this embodiment is similar to that in Embodiment 1, except that the gas guiding channel 110 is located outside the smoke generating section body 100, and the gap between the serrations on the outside of the smoke generating section body 100 and the splicing paper 200 constitutes the gas guiding channel 110.

[0044] The smoke-generating section body 100 has a diameter of 6.0-7.3 mm, a length of 5-35 mm, and a porosity of 20-50%. The tested smoke concentration is 50%.

[0045] Example 3

[0046] A solid aerosol product, see [link to product description] Figure 5 It includes: a filter component 300, a support component 400, a smoke generating component 500 and a functional component 600 arranged sequentially from the near lip end to the far lip end, wherein the smoke generating component 500 adopts the aforementioned solid aerosol generating matrix.

[0047] The filter element 300 and the functional element 600 are made of cellulose acetate rods or paper rods.

[0048] The filter element 300 has a length of 7-12mm, the support element 400 has a length of 18-23mm, the smoke generating element 500 has a length of 8-12mm, and the functional element 600 has a length of 5-8mm.

[0049] The suction resistance of the filter component 300 is greater than that of the functional component 600, which in turn causes the smoke to be emitted to the component 500. The suction resistance of the support component 400 is greater than that of the filter component 300.

[0050] Example 4

[0051] A solid aerosol generation system, see Figure 6 The solid aerosol generation system includes an aerosol generation device and the aforementioned solid aerosol generation product. The aerosol generation device includes a heating element 700, which is used to heat the solid aerosol generation matrix to generate aerosols.

[0052] Comparative Example 1

[0053] Similar to the steps in Example 1, the only difference is that the air guide channel 110 is not provided, resulting in a suction resistance greater than 1000Pa, which leads to a smoke concentration of less than 30%.

[0054] Comparative Example 2

[0055] Similar to the steps in Example 1, the only difference is that micropores 120 were not provided, resulting in a smoke concentration of less than 35%.

[0056] Comparative Example 3

[0057] Similar to the steps in Example 1, the only difference is that the diameter of the smoke-generating section body 100 is 5.0 or 7.5 mm, resulting in a smoke concentration of less than 35%.

[0058] Comparative Example 4

[0059] Similar to the steps in Example 1, the only difference is that the length of the smoke-generating section body 100 is 3.0 or 40.0 mm, resulting in a smoke concentration of less than 25%.

[0060] Comparative Example 5

[0061] Similar to the steps in Example 1, the only difference is that the porosity of the smoke-generating section body 100 is 10%, resulting in smoke concentrations all below 28%.

[0062] Comparative Example 6

[0063] Similar to the steps in Example 3, the only difference is that the length ratio of the support component 400 to the entire solid aerosol product is 0.4:1. As a result, the smoke concentration is less than 38%, and the heat is too high, making it easy to burn the mouth, resulting in a poor inhalation experience.

[0064] The results above show that both the gas-guiding channel 110 and the micropores 120 within the solid aerosol generation matrix are indispensable; their absence reduces the total amount of aerosol released. If the diameter of the smoke-generating section is too small, the unit weight is low, resulting in a smaller total amount of released substances; if the diameter is too large, uneven internal heat transfer reduces the amount of effective components that can be released. Therefore, the diameter of the smoke-generating section needs to be within a reasonable range. Similarly, if the length is too short, the total amount of released substances is low; if the length is too long, it places higher demands on the heating element and motor power, and also increases costs. Therefore, it needs to be within a reasonable range. If the porosity is too low, the aerosol components generated when the components inside the smoke-generating component 500 are heated cannot be released in time and will deposit inside. There are also certain requirements for the length ratio of the support component 400 to the entire solid aerosol product. If it is too low (<0.5:1), the support component 400 will be too short while the smoke-generating component 500 and the functional component 600 will be too long, resulting in a large cooling load when the entire aerosol product is drawn in. At the same time, if it is too high (>0.8:1), the smoke-generating component 500 and the functional component 600 will be too short, resulting in fewer substances being released and a lower smoke concentration.

[0065] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
