Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0027] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0029] Please see Figure 1 and Figure 2 This application provides an aerosol generating device 100 (hereinafter referred to as "generating device 100") for heating an aerosol generating product 200 to generate aerosol using the principle of heating without combustion. The generating device 100 includes a heating component 120 and a power supply component 130. The heating component 120 has a heating chamber 121 for accommodating the aerosol generating product 200. The power supply component 130 is electrically connected to the heating component 120 and is used to supply power to the heating component 120. After being powered on, the heating component 120 generates heat to provide heat to the aerosol generating product 200, causing it to generate aerosol at a certain temperature. The heating component 120 can generally heat the aerosol generating product 200 by circumferential heating, central heating, or airflow heating.

[0030] The generating device 100 also includes a housing 110, which has a cavity for accommodating the heating component 120 and the power supply component 130, thus connecting the heating component 120 and the power supply component 130 into a single structure and protecting them, facilitating the carrying and transportation of the generating device 100. The housing 110 also has an opening that exposes the control keys of the power supply component 130 for user control and operation of the generating device 100.

[0031] The heating assembly 120 includes a heating element, which can be a cylindrical structure or a rod-shaped structure. When the heating element is cylindrical, it encloses a heating cavity 121. The heating element can be made of a conductive resistive material (such as metal or conductive ceramic) or include a heating film, heating circuitry, etc. After being energized, the heating element heats up and provides heat to the aerosol generating product 200 circumferentially, achieving circumferential heating. Alternatively, the heating assembly 120 may also include a heat exchanger, which is disposed within the heating cavity 121 to heat the airflow entering the heating cavity 121, thereby heating the aerosol generating product 200 using an airflow heating method. When the heating element is rod-shaped, it can be inserted into the interior of the aerosol generating product 200 and heats up centrally after being energized.

[0032] Please see Figures 3 to 7 In another aspect, this application provides an aerosol generating article 200, including a nozzle section 210, an intermediate section 220, and a matrix section 230. The nozzle section 210 is the end closest to the user (or the user's mouth) and is used to filter aerosols. The intermediate section 220 is disposed at one end of the nozzle section 210 along the length of the aerosol generating article. The intermediate section 220 is the part for aerosol flow and cooling, which can reduce the temperature of the aerosol and prevent burns to the user. The matrix section 230 is disposed at the end of the intermediate section 220 away from the nozzle section 210, which is the end furthest from the user (or the user's mouth). The matrix section 230 is used to generate aerosols for the user after heating. In use, the matrix section 230 is housed in a heating chamber 121, and the length of the matrix section 230 is less than or equal to the length of the heating chamber 121, thereby ensuring that the matrix section 230 is completely heated. The matrix section 230 includes a base matrix and a functional matrix. The base matrix is ​​used to generate a first aerosol, and the functional matrix is ​​used to increase the thermal conductivity of the matrix section 230. The functional matrix is ​​also used to generate a second aerosol, which is used to mix with the first aerosol and flow through the intermediate section 220 to the nozzle section 210.

[0033] It should be noted that the term "aerosol" in this context refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used herein can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0034] As used herein, the term "base matrix" is generally understood as aerosol-generating article 200, referring to any suitable compound or mixture of compounds that facilitates the formation of aerosols (e.g., stable aerosols that are substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable aerosol-generating articles 200 are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono, di, or triacetic acid esters of glycerol; and aliphatic esters of mono, di, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Aerosol-generating article 200 may include nicotine. Aerosol-generating article 200 may include water. Aerosol-generating article 200 may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Aerosol-generating article 200 may include propylene glycol. Aerosol-generating article 200 may include plant-based materials. Aerosol-generating article 200 may include homogeneous plant matrix materials. In this application, the "base matrix" is a solid sheet or columnar structure, formed by rolling or pressing paper. During the forming process, many pores are formed inside the base matrix. These pores reduce the thermal conductivity of the base matrix, which makes it easy for the aerosol to form slowly or burn at high temperature.

[0035] Unlike traditional aerosol generating products 200, the matrix segment 230 in this application includes a basic matrix and a functional matrix. The basic matrix is ​​used to generate the first aerosol, and the functional matrix can increase the thermal conductivity of the matrix segment 230. The higher thermal conductivity allows the matrix segment 230 to generate aerosols quickly and also allows all the structures of the matrix segment 230 to quickly distribute the heat, avoiding heat accumulation and high-temperature burning. This improves the service life of the aerosol generating product 200 and the aerosol generating device 100, and also improves the user experience.

[0036] In some embodiments, the matrix segment 230 includes a base matrix and a functional matrix. The functional matrix includes a liquid aerosol forming matrix, and the base matrix includes a solid aerosol forming matrix. The functional matrix can be completely mixed with the base matrix and completely fill the base matrix. During preparation, the functional matrix first forms the overall shape of the matrix segment 230, and then is added by means of infusion or other methods. The functional matrix fills the pores of the base matrix to form the matrix segment 230. The liquid aerosol forming matrix can generate a second aerosol after heating. The second aerosol can mix with the first aerosol and flow through the intermediate segment 220 to the nozzle segment 210. In use, due to the thorough mixing of the functional matrix and the base matrix, the entire matrix segment 230 can conduct heat rapidly in the axial or radial direction, and can be heated by circumferential heating, central heating, or airflow heating.

[0037] Understandably, the main components of the functional matrix are the same as those of the base matrix, which are any suitable compounds or mixtures of compounds that facilitate aerosol formation. The difference between the functional matrix and the base matrix is ​​that the functional matrix is ​​liquid.

[0038] The presence of the liquid functional matrix fills the pores in the base matrix, thereby increasing the thermal conductivity of the matrix segment 230. Furthermore, due to capillary action, phase change energy transfer is achieved, significantly increasing the thermal conductivity of the matrix segment 230. This allows heat to diffuse and be absorbed rapidly throughout the entire matrix segment 230. The increased energy absorption rate of the matrix segment 230 enables rapid preheating, leading to faster aerosol generation and increasing the aerosol formation rate. The significantly increased thermal conductivity of the matrix segment 230 also ensures a more uniform temperature, preventing the accumulation of heat that could cause burning and a burnt smell. Simultaneously, the liquid aerosol forming matrix also generates a second aerosol (with the same composition as the first aerosol) upon heating, increasing the amount of aerosol generated per unit time. This increases the total amount of aerosol generated without changing the overall volume of the matrix segment 230, enhancing user satisfaction.

[0039] Of course, in other embodiments, the functional matrix may not be mixed with the base matrix; that is, the matrix segment includes a first part and a second part, the first part including only the functional matrix and the second part including only the base matrix. Since the functional matrix is ​​a liquid aerosol-formed matrix, it has a higher density, fewer pores, and a higher thermal conductivity than the base matrix, allowing the first part to distribute heat more quickly and evenly compared to the base matrix.

[0040] In other embodiments, the functional matrix may also be other aerosol-generating substances that can increase the thermal conductivity of the base matrix, and the density of the functional matrix is ​​greater than that of the base matrix, thereby increasing the thermal conductivity of the matrix segment.

[0041] In some embodiments, in the matrix segment 230 comprising a base matrix and a functional matrix, the mass percentage of the functional matrix is ​​greater than 20%. If the content of the functional matrix is ​​too low, there will be insufficient filling of pores, resulting in a less significant increase in thermal conductivity. Therefore, the mass percentage of the functional matrix in the matrix segment 230 can be 25%, 30%, 40%, 50%, or 90%, etc. Specifically, when the matrix segment is divided into a first part comprising both a functional matrix and a base matrix and a second part comprising only a base matrix, the mass percentage of the functional matrix in the first part is greater than 20%.

[0042] In some embodiments, the matrix segment 230 may include a plurality of layer structures disposed radially thereon, at least one layer structure including a functional matrix. Because at least one layer structure includes a functional matrix, the thermal conductivity of the layer structure is relatively high, and the heat conduction and transfer are relatively fast, so that aerosols can be rapidly generated at the layer structure.

[0043] At least one layer structure includes a functional matrix, and the remaining layer structures include a base matrix. The thermal conductivity of the base matrix is ​​less than that of the functional matrix, thereby allowing the generated aerosol to be released gradually and achieving consistency of the aerosol before and after.

[0044] In some embodiments, at least one layer structure includes a functional matrix and a base matrix, while the remaining layer structures are base matrices. Similarly, the addition of a functional matrix can increase the thermal conductivity of the layer structure, thereby improving the aerosol generation rate and the consistency of the entire matrix segment 230 before and after aerosol formation. In use, because the layer structure containing the functional matrix has a higher thermal conductivity, it is placed near the heat source.

[0045] In some embodiments, when a central heating method is used, the percentage of the mass of the functional matrix in a single layer structure arranged radially in the matrix segment 230 can gradually increase from the outside to the inside, so that the percentage of the functional matrix in the layer structure near the central heating element is the largest.

[0046] In other embodiments, when circumferential heating is used, the percentage of the mass of the functional matrix in a single layer structure arranged radially in the matrix segment 230 can gradually increase from the inside to the outside, so that the percentage of the functional matrix in the layer structure near the peripheral heating element is the largest.

[0047] Please see Figure 4 In some embodiments, the matrix segment 230 includes an inner layer 231 and an outer layer 232 arranged radially from the inside to the outside. The inner layer 231 includes a base material and a functional matrix filled within the base matrix, while the outer layer 232 includes the base matrix. Therefore, the thermal conductivity of the inner layer 231 is greater than that of the outer layer 232, allowing the inner layer 231 to quickly distribute heat. When a central heating method is selected, the temperature in the center is too high. To accelerate heat transfer, an aerosol-generating product 200 with this structure can be used.

[0048] In other embodiments, the matrix segment 230 includes an inner layer 231 and an outer layer 232 arranged radially from the inside to the outside. The outer layer 232 includes a base material and a functional matrix filled within the base matrix, while the inner layer 231 includes the base matrix. Therefore, the thermal conductivity of the outer layer 232 is greater than that of the inner layer 231, allowing the outer layer 232 to quickly distribute heat. When using a circumferential heating method, because the temperature on the periphery is too high, this type of aerosol-generating product 200 can be selected to accelerate heat transfer.

[0049] In some embodiments, the matrix segment 230 may also include a plurality of segment structures disposed along its length, at least one segment structure including a functional matrix. Because at least one segment structure includes a functional matrix, the segment structure has a high thermal conductivity and conducts heat quickly, thus aerosols can be rapidly generated at the segment structure.

[0050] At least one segment structure includes a functional matrix, and the remaining segment structures include a base matrix. The thermal conductivity of the base matrix is ​​lower than that of the functional matrix, thereby allowing the generated aerosol to be released gradually and achieving consistency of the aerosol before and after.

[0051] In some embodiments, at least one segment structure has a functional matrix within its base matrix, meaning that at least one segment structure includes both a functional matrix and a base matrix, while the remaining segment structures only include the base matrix. Since at least one segment structure has a functional matrix within its base matrix, and the remaining segment structures are base matrices, the segment structure containing the functional matrix has a higher thermal conductivity and faster heat conduction, allowing for rapid aerosol generation at that segment structure.

[0052] In some embodiments, the segment structure near the nozzle segment 210 contains a functional matrix, which, when in use, can rapidly generate an aerosol and allow the aerosol to reach the nozzle segment 210 for use by the user via the shortest path.

[0053] In other embodiments, when using airflow heating, since the airflow flows from bottom to top (in the direction from the end away from the nozzle section 210 to the end near the nozzle section 210), in order to increase thermal efficiency, the section away from the nozzle section 210, which contains the largest proportion of functional matrix content in the multiple section structures, can also be set to increase thermal efficiency.

[0054] In some embodiments, the percentage of the functional matrix in the mass of the segment structure gradually increases from the end away from the nozzle segment 210 to the end closer to the nozzle segment 210, so that the proportion of the functional matrix in the segment structure closer to the nozzle segment 210 is the largest.

[0055] Please see Figure 5The matrix section 230 includes a first section 233 and a second section 234 arranged sequentially along its length. The first section 233 is located near the middle section 220 and includes a base material and a functional matrix filled within the base matrix. The second section 234 includes the base material. Because the functional matrix is ​​filled within the base matrix of the first section 233, its thermal conductivity is increased, resulting in faster heat conduction and rapid aerosol generation. Furthermore, the proximity of the first section 233 to the middle section 220 allows the generated aerosol to flow quickly into the mouthpiece section 210, enabling the user to quickly obtain the aerosol and thus enhancing user satisfaction. The second section 234 generates aerosol more slowly than the first section 233, but its aerosol mixes with that of the first section 233, resulting in a more uniform aerosol distribution throughout the user's experience and further improving the user's suction experience.

[0056] In some embodiments, the functional matrix may also include auxiliary substances that can enrich the flavor of the aerosol to meet the needs of different users. For example, the auxiliary substances may be a peppermint extract matrix that can increase the cooling sensation, or a matrix that can increase sweetness, such as fruit extracts or flower extracts.

[0057] Please see Figure 6 In some embodiments, the intermediate section 220 includes a hollow section 221 and a cooling section 222. The hollow section 221 is provided with through holes for guiding aerosol, and the cooling section 222 may be provided with solid material to reduce the temperature of the aerosol.

[0058] Please see Figure 7 In some embodiments, the aerosol generating article 200 further includes a sponge segment 240 disposed at the end of the matrix segment 230 away from the intermediate segment 220, which can prevent the matrix segment 230 from falling off.

[0059] In some embodiments, the aerosol generating article 200 further includes an outer forming paper that can be wound into a cylindrical shape and wraps the nozzle section 210, the middle section 220, the matrix section 230 and the sponge section 240 to form a whole.

[0060] This application also provides an aerosol generation system, including an aerosol generation device 100 and an aerosol generation article 200. The aerosol generation article 200 is housed in the heating chamber 121 of the aerosol generation device 100. The aerosol generation device 100 and the aerosol generation article 200 have been described in detail above, and will not be repeated here.
