Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and in particular to an aerosol product and a heat-not-burn system. Background Art

[0002] Aerosol products can generate aerosols when heated. In related art, the aerosol generation rate of aerosol products is low during the initial heating phase, and only increases after a period of heating. This results in poor puff consistency during the inhalation of the aerosol products. Utility Model Content

[0003] The present application provides an aerosol product and a heat-not-burn system, which can improve the puff-by-puff consistency during the process of inhaling the aerosol product.

[0004] In a first aspect, the present application provides an aerosol product for use with a heating device, the aerosol product comprising a filter portion and a matrix portion. The matrix portion is solid, and the heating device is configured to heat the matrix portion in a predetermined direction to generate an aerosol. The matrix portion is disposed on the inlet side of the filter portion, and the density of the matrix portion gradually increases along the predetermined direction.

[0005] In some implementations of the present application, the average density of the matrix is 0.1 to 4 mg / mm 3 .

[0006] In some implementations of the present application, the compactness of the matrix portion gradually increases along a preset direction, so that the density of the matrix portion gradually increases.

[0007] In some implementations of the present application, along a preset direction, the size of the matrix units of the matrix portion gradually decreases, so that the density of the matrix portion gradually increases.

[0008] In some implementations of the present application, the matrix portion includes at least two matrix sub-portions, and the sizes of the matrix units in the same matrix sub-portion are consistent; along a preset direction, the sizes of the matrix units of at least two adjacent matrix sub-portions decrease successively, so that the density of the matrix portion gradually increases.

[0009] In some implementations of the present application, the density of each matrix sub-portion gradually increases along a preset direction.

[0010] In some implementations of the present application, the direction from the filter portion to the matrix portion is the same as or opposite to the preset direction.

[0011] In some implementations of the present application, the preset direction is a direction from the periphery toward the center of the matrix portion, or the preset direction is a direction from the center toward the periphery of the matrix portion.

[0012] In some implementations of the present application, an induction heating element is provided on the outer peripheral surface of the matrix portion, and the preset direction is from the outer periphery of the matrix portion towards the center; alternatively, an induction heating element is provided at the center of the matrix portion, and the preset direction is from the center of the matrix portion towards the outer periphery.

[0013] In a second aspect, the present application provides a heat-not-burn system, which includes a heating device and the aerosol product provided in the first aspect of the present application, and the heating device is used to heat the aerosol product.

[0014] For the aerosol product provided by the present application, along the preset direction, the density of the matrix portion gradually increases. The portion of the matrix portion with a small density has a small thermal conductivity. After being heated, heat is not easily transferred to other parts of the matrix portion. The heating device is used to heat the matrix portion along the preset direction, so that in the initial stage of heating, the portion of the matrix portion with a small density is more likely to receive the heat transferred by the heating element and quickly accumulate heat. This enables the portion of the matrix portion with a small density to be fully heated in the initial stage of heating, thereby generating aerosol at a relatively high rate, so that when a person takes the first puff, the aerosol product can quickly produce smoke. After heating for a period of time, a large amount of the portion of the matrix portion with a small density is consumed, and the rate of aerosol generation is small. As time goes by, the portion of the matrix portion with a large density absorbs more and more heat and can also be fully heated, resulting in a relatively high rate of aerosol generation. In this way, during the entire heating process, the rate of aerosol generation in the matrix portion is relatively high, which is beneficial to improving puff-to-puff consistency.

And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0029] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a heat not burn (HNB) system. The heat not burn system includes a heating device 2 and an aerosol article 1. The heating device 2 is used to heat the aerosol article 1 to a temperature capable of generating aerosol, but the temperature is not sufficient to cause the aerosol article 1 to burn, so that there are fewer harmful substances in the aerosol, which is beneficial to health.

[0030] Please refer to Figure 1 and Figure 2 , the aerosol article 1 provided by the embodiment of the present application is used in cooperation with the heating device 2. The aerosol article 1 includes a filter part 11 and a matrix part 12. Among them, the matrix part 12 is in a solid state, and the heating device 2 is used to heat the matrix part 12 to generate aerosol; the matrix part 12 is arranged on the inlet side of the filter part 11. In this way, the harmful substances in the aerosol generated by the matrix part 12 are reduced after being filtered by the filter part 11, which is beneficial to health. The filter part 11 has an inlet and an outlet. The matrix part 12 is arranged on the inlet side of the filter part 11, that is, the inlet of the filter part 11 faces the matrix part 12. The aerosol generated by the matrix part 12 enters the filter part 11 through the inlet, and is discharged through the outlet of the filter part 11 after being filtered by the filter part 11, so that the harmful substances in the aerosol are reduced.

[0031] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the aerosol article 1 includes a housing 13. The housing 13 forms an installation cavity 131. The installation cavity 131 has a mouthpiece. Both the filter part 11 and the matrix part 12 are arranged in the installation cavity 131, and the filter part 11 is located on the side of the matrix part 12 close to the mouthpiece. In this way, the aerosol flows out of the installation cavity 131 through the filter part 11 and the mouthpiece in sequence. The housing 13 can support the filter part and the matrix part 12, and the reliability of the aerosol article 1 is relatively high and it is not easy to be damaged.

[0032] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the housing 13 may be a hard paper tube, wrapping paper, etc. In this way, the cost of the housing 13 is relatively low, and no harmful substances are easily generated when heated. Generally, when the matrix units of the matrix part 12 are filamentous or granular, the housing 13 may be a hard paper tube; when the matrix units of the matrix part 12 are filamentous or sheet-like, the housing 13 may also be wrapping paper.

[0033] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the aerosol product 1 further includes a baffle 14. The baffle 14 is fixed in the installation cavity 131 and is located between the filtering part 11 and the matrix part 12. The filtering part 11 and the baffle 14 are spaced apart from each other, and a cooling cavity 1311 is formed therebetween. It can be understood that the cooling cavity 1311 is a part of the installation cavity 131. By providing the cooling cavity 1311, the temperature of the aerosol discharged from the mouthpiece can be reduced, which is beneficial to improving the safety of the aerosol product 1.

[0034] Please refer to Figure 1 and Figure 2 In the embodiments of the present application, the heating device 2 includes a heating element. The heating device 2 heats the aerosol product 1. The heating element may be in contact with the aerosol product 1 to heat the aerosol product 1, or the heating element may be spaced apart from the aerosol product 1. The heating element heats the air, and the hot air heats the aerosol product 1.

[0035] Please refer to Figure 1 and 2 In some embodiments of the present application, the heating element may be a central heating element such as an induction heating element 15. The induction heating element 15 can generate eddy currents under the action of an alternating magnetic field, thereby releasing heat.

[0036] Please refer to Figure 3 、 4 and Figure 8 In some embodiments of the present application, the heating element may be a resistance heating element. The resistance heating element includes a resistor body. The resistor body is electrically connected to the battery 22. The battery 22 supplies power to the resistor body to allow current to pass through the resistor body. The resistor body has a relatively high resistance and will generate a Joule effect when current passes through, thereby releasing heat.

[0037] In some embodiments of the present application, the resistance heating element may be an electric heating tube 23 (such as Figure 3 and Figure 4 ), an electric heating needle, an electric heating sheet, or an electrothermal ceramic element 24 (such as Figure 8 ) and so on.

[0038] It should be noted that, please refer toFigure 3 and Figure 4 In the embodiments of the present application, the electric heating tube 23 has the same meaning as that generally understood by those skilled in the art of the present application. Generally, it includes a metal tube and a resistance wire arranged on the inner surface of the metal tube. The resistance wire is in a spiral shape, and the axis of the spiral shape is the same as the axis of the metal tube.

[0039] It should be noted that in the embodiments of the present application, the electric heating needle and the electric heating sheet have the same meaning as that generally understood by those skilled in the art of the present application. Generally, the electric heating needle includes a metal rod or a ceramic rod, and the electric heating sheet includes a metal heating sheet or a ceramic heating sheet.

[0040] It should be noted that in the embodiments of the present application, please refer to Figure & , the electrothermal ceramic member 24 includes a heat storage ceramic 241 and a resistor body. The resistor body is in thermal contact with the heat storage ceramic 241 and is used to heat the heat storage ceramic 241. The heat storage ceramic 241 has a strong heat storage capacity and can continuously heat the aerosol matrix relatively stably. On this basis, in some embodiments of the present application, the resistor body can be an electric heating wire 242, and the electric heating wire 242 is wound around the heat storage ceramic or attached to the end face of the heat storage ceramic. In some embodiments of the present application, the heat storage ceramic 241 has a porous structure. In this way, the heat storage ceramic 241 has a large contact area with the air and can provide sufficient hot air flow for the matrix part 12.

[0041] Please refer to Figure 1 and Figure 2 , generally, the heating device 2 further includes a housing 21, and the battery 22 is arranged on the housing 21. On this basis, the heating element can be arranged on the housing 21 or on the aerosol article 1.

[0042] Please refer to Figure 3 , 4 and Figure 8 , exemplarily, in some embodiments of the present application, the heating element is a resistive heating element, and the battery 22 is used to supply power to the heating element. The heating element is arranged on the housing 21, and the heating element, the housing 21 and the battery 22 are integrated together. The heating element does not need to be replaced frequently, which is beneficial to reducing costs.

[0043] In some embodiments of the present application, the heating element is an induction heating element 15, and the induction heating element 15 is arranged on the outer peripheral surface of the matrix part 12. In some embodiments, please refer to Figure 1 and Figure 2, the induction heating element 15 can also be disposed at the center of the matrix portion 12. The heating device 2 further includes an induction coil disposed on the housing 21. The battery 22 is used to supply power to the induction coil, and the induction coil is used to cause the induction heating element 15 to generate eddy currents to heat the matrix portion 12. The induction heating element 15 has a relatively low cost and is integrated on the aerosol article 1, and it is not easy to significantly increase the cost. Moreover, whether the induction heating element 15 is disposed on the outer peripheral surface of the matrix portion 12 or at the center of the matrix portion 12, the contact between the induction heating element 15 and the matrix portion 12 is relatively tight, so that the induction heating element 15 can heat the matrix portion 12 more sufficiently.

[0044] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the housing 21 forms a receiving cavity 211, and the aerosol article 1 is detachably engaged with the receiving cavity 211. In this way, on the one hand, the installation of the aerosol article 1 and the housing 21 is relatively stable, and on the other hand, the disassembly and assembly of the aerosol article 1 on the housing 21 is relatively convenient, facilitating the replacement of the aerosol article 1.

[0045] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the matrix portion 12 is disposed in the receiving cavity 211. In this way, the receiving cavity 211 can fit around the periphery of the matrix portion 12, so that the aerosol generated after the matrix portion 12 is heated is not easily leaked out from the periphery of the receiving cavity 211, but is sucked out from the aerosol article 1.

[0046] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the receiving cavity 211 has an opening, and the aerosol article 1 extends out of the receiving cavity 211 through the opening, and the portion extending out of the receiving cavity 211 has a filtering portion 11. In this way, the filtering portion 11 is located outside the receiving cavity 211, and a person can easily reach the filtering portion 11 to suck on the outlet end of the filtering portion 11.

[0047] Please refer to Figure 1 and Figure 2, in the embodiments of the present application, the heating device 2 is used to heat the matrix part 12 along a preset direction. Along the preset direction, the density of the matrix part 12 gradually increases. In this way, the part of the matrix part 12 with a small density has a small thermal conductivity. After being heated, the heat is not easily transferred to other parts of the matrix part 12. The heating device 2 is used to heat the matrix part 12 along the preset direction, so that in the initial stage of heating, the part of the matrix part 12 with a small density is more likely to receive the heat transferred by the heating element and quickly accumulate heat. This enables the part of the matrix part 12 with a small density to be fully heated in the initial stage of heating, thereby generating aerosol at a relatively high rate, so that when a person takes the first puff, the aerosol product 1 can quickly produce smoke. After heating for a period of time, the part of the matrix part 12 with a small density is consumed in large quantities, and the rate of aerosol generation is small. As time goes by, the part of the matrix part 12 with a large density absorbs more and more heat and can also be fully heated, resulting in a relatively high rate of aerosol generation. In this way, during the entire heating process, the rate of aerosol generation by the matrix part 12 is relatively high, which is beneficial to improving the puff-to-puff consistency.

[0048] Please refer to Figure 1 and Figure 2 , it can be understood that in the embodiments of the present application, after the part of the matrix part 12 with a large density is fully heated, the amount of aerosol generated per unit volume is relatively large, which is beneficial to increasing the total amount of aerosol that the aerosol product 1 can generate.

[0049] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the average density of the matrix part 12 is 0.1 - 4 mg / mm 3 . In this way, the density of the matrix part 12 is moderate, so that only a limited amount of the matrix part 12 in the aerosol product 1 is required to ensure an appropriate amount of aerosol, which not only saves the puffing cost but also takes into account the puffing experience.

[0050] Please refer to Figure 1 and Figure 2 , it should be explained that in the embodiments of the present application, the heating element is a central heating element, and the "preset direction" is the direction from the center of the matrix part 12 towards the outer periphery. The heating device 2 is used to heat the matrix part 12 along the preset direction, that is, the heat generated by the heating device 2 is conducted in the matrix part 12 along the preset direction. Along the preset direction, the matrix part 12 is gradually and fully heated, and thus gradually releases aerosol.

[0051] Please refer to Figure 1 and Figure 2 , along the preset direction, the density of the matrix part 12 gradually increases, that is, along the preset direction, the thermal conductivity of the matrix part 12 gradually increases, so that each part of the matrix part 12 can quickly and fully accumulate heat, which is beneficial to improving the puff-to-puff consistency.

[0052] Exemplarily, please refer to Figure 1 and Figure 2 , the densities of the first matrix proton part 1201, the second matrix proton part 1202 and the third matrix proton part 1203 increase in sequence, and the heat generated by the heating device is sequentially transferred to the first matrix proton part 1201, the second matrix proton part 1202 and the third matrix proton part 1203. The thermal conductivity of the first matrix proton part 1201 is small. At the initial stage of heating, the first matrix proton part 1201 can quickly receive the heat transferred by the heating element and rapidly accumulate heat, which enables the first matrix proton part 1201 to be fully heated at the initial stage of heating, so as to generate aerosol at a relatively large rate. The thermal conductivity of the second matrix proton part 1202 is moderate and the heating rate is moderate. After heating for a certain period of time, the first matrix proton part 1201 is largely consumed and the rate of generating aerosol is small. At this time, the second matrix proton part 1202 has been heated for a certain period of time, can reach a high temperature state, is fully heated, and generates aerosol at a relatively large rate. The thermal conductivity of the third matrix proton part 1203 is large and the heating rate is low. After heating for a long time, both the first matrix proton part 1201 and the second matrix proton part 1202 are largely consumed and the rates of generating aerosol are both small. At this time, the third matrix proton part 1203 has been heated for a long time, can be fully heated, and generates aerosol at a relatively large rate. In this way, during the whole heating process, the rate of generating aerosol of the aerosol product 1 is relatively large, which is beneficial to improving the puff-to-puff consistency.

[0053] Refer to Figure 1 and Figure 2 , in some embodiments of the present application, the preset direction is the direction from the center of the matrix part 12 towards the outer periphery. In the direction from the center of the matrix part 12 towards the outer periphery, the density of the matrix part 12 gradually increases. In this way, the matrix part 12 surrounds the heating element, which is beneficial to fully heating the matrix part 12, so as to fully generate aerosol.

[0054] It can be understood that in the embodiments of the present application, the matrix part 12 encloses a cavity, the heating element is arranged in the cavity, the preset direction is the direction from the inner surface of the cavity to the outer periphery of the matrix part 12. In the direction from the inner surface of the cavity to the outer periphery of the matrix part 12, the density of the matrix part 12 gradually increases. The center of the matrix part 12, i.e., the inner surface of the cavity, is the hot end, and the outer periphery of the matrix part 12 is the cold end. The cold end and the hot end are relative to each other. The heat generated by the heating device 2 is transferred from the center of the matrix part 12 towards the outer periphery. In the direction from the center of the matrix part 12 towards the outer periphery, the matrix part 12 is gradually heated, so as to gradually release aerosol.

[0055] It can be understood that in the embodiments of the present application, the thermal conductivity at the center of the matrix part 12 is relatively small, and the heating rate is relatively large. At the initial stage of heating, the center of the matrix part 12 can quickly receive the heat transferred by the heating element and rapidly accumulate heat, and can be fully heated, so as to generate aerosol at a relatively large rate. When a person takes the first puff, the aerosol product 1 can quickly produce smoke. The thermal conductivity of the outer periphery of the matrix part 12 is relatively large, and the heating rate is relatively low. After heating for a long time, the center of the matrix part 12 is consumed in large quantities, and the rate of generating aerosol is relatively small. At this time, the outer periphery of the matrix part 12 has been heated for a long time and can be fully heated to generate aerosol at a relatively large rate. In this way, during the entire heating process, the rate of generating aerosol by the aerosol product 1 is relatively large, which is beneficial to improving the puff-to-puff consistency.

[0056] In some embodiments of the present application, the inner surface of the cavity can be attached to the heating element, which is beneficial to improving the heating effect.

[0057] Please refer to Figure 1 and Figure 2 , in this embodiment, the shape of the heating element can have various implementation forms. Exemplarily, it can be a sheet structure or a needle structure, etc., and the embodiments of the present application do not limit this. In the embodiments of the present application, the heating element can be a resistive heating element or an induction heating element 15, etc., and the embodiments of the present application do not make any restrictions.

[0058] Please refer to [[ID=&9]]Figure 3 and Figure 4 , in some embodiments of the present application, the preset direction is from the outer periphery of the matrix part 12 towards the center, and the density of the matrix part 12 gradually increases. In this way, the heating element surrounds the matrix part 12 to heat the matrix part 12, which is beneficial to fully heating the matrix part 12 and thus fully generating aerosol.

[0059] It can be understood that in the embodiments of the present application, the heating element encloses a heating cavity, the matrix part 12 is arranged in the heating cavity, the preset direction is from the inner surface of the heating cavity to the matrix part 12, and from the inner surface of the heating cavity to the matrix part 12, the density of the matrix part 12 gradually increases. The outer periphery of the matrix part 12, that is, the part of the matrix part 12 close to the inner surface of the heating cavity, is the hot end, and the center of the matrix part 12 is the cold end. The cold end and the hot end are relative to each other. The heat generated by the heating device 2 is transferred from the outer periphery of the matrix part 12 towards the center, and the matrix part 12 is gradually heated from the outer periphery of the matrix part 12 towards the center, thereby gradually releasing aerosol.

[0060] It can be understood that in the embodiments of the present application, the thermal conductivity coefficient at the outer periphery of the matrix part 12 is small and the heating rate is large. At the initial stage of heating, the outer periphery of the matrix part 12 can quickly receive the heat transferred by the heating element and rapidly accumulate heat, and can be fully heated, so as to generate aerosol at a relatively large rate. When a person takes the first puff, the aerosol product 1 can quickly produce smoke. The thermal conductivity coefficient at the center of the matrix part 12 is large and the heating rate is low. After heating for a long time, the outer periphery of the matrix part 12 is largely consumed and the rate of generating aerosol is small. At this time, the center of the matrix part 12 has been heated for a long time and can be fully heated to generate aerosol at a relatively large rate. In this way, during the whole heating process, the rate of generating aerosol by the aerosol product 1 is relatively large, which is beneficial to improving the puff-to-puff consistency.

[0061] Please refer to Figure 3 and Figure 4 , in some embodiments of the present application, the heating element is a heating tube 23, and the heating element is sleeved on the outer surface of the housing 13, and the heating element is correspondingly arranged with the matrix part 12. In this way, it is convenient to assemble the heating element and the aerosol product 1.

[0062] In some embodiments of the present application, the heating element is an induction heating element 15, and the induction heating element 15 surrounds the outer peripheral surface of the matrix part 12. In this way, the heating element is in direct contact with the matrix part 12, which is beneficial to fully heating the matrix part 12.

[0063] Please refer to Figure 5 and Figure 6 , in some embodiments of the present application, the direction from the filter part 11 to the matrix part 12 is the same as or opposite to the preset direction. With such a structural form, it is more convenient to manufacture the matrix part 12, and it is also more convenient to assemble the heating element and the matrix part 12. The arrangement direction of the filter part 11 and the matrix part 12 can refer to the first direction y in the figure.

[0064] Please refer to Figure 7 and Figure 8 , generally, along the arrangement direction of the filter part 11 and the matrix part 12, an air inlet is formed on the end surface of the housing 13 at the end away from the filter part 11. During the process of a person sucking the filter part 11, air enters the housing 13 through the air inlet, and sequentially passes through the matrix part 12 and the filter part 11 and then exits the housing 13. On this basis, in some embodiments of the present application, the air inlet faces the heating element, and the direction from the filter part 11 to the matrix part 12 is opposite to the preset direction, that is, along the direction from the filter part 11 to the matrix part 12, the density of the matrix part 12 gradually decreases. In this way, during the process of a person sucking the aerosol product 1, the hot air heated by the heating element can pass through the matrix part 12 along the preset direction under the sucking action, which is beneficial to fully heating the matrix part 12.

[0065] It can be understood that in the embodiments of the present application, one end of the matrix part 12 far from the filtering part 11 has a relatively small thermal conductivity and a relatively large heating rate. At the initial stage of heating, the end of the matrix part 12 far from the filtering part 11 can quickly receive the heat transferred by the heating element and rapidly accumulate heat, and can be fully heated, so as to generate aerosol at a relatively large rate. When a person takes the first puff, the aerosol product 1 can quickly produce smoke. One end of the matrix part 12 close to the filtering part 11 has a relatively large thermal conductivity and a relatively low heating rate. After heating for a long time, a large amount of the end of the matrix part 12 far from the filtering part 11 is consumed, and the rate of generating aerosol is relatively small. At this time, the end of the matrix part 12 close to the filtering part 11 has been heated for a long time and can be fully heated to generate aerosol at a relatively large rate. In this way, during the whole heating process, the rate of generating aerosol of the aerosol product 1 is relatively large, which is beneficial to improving the puff-to-puff consistency.

[0066] Please refer to Figure 7 and Figure 8 , on this basis, the heating element is an electrothermal ceramic element 24, and the heat storage ceramic 241 has a strong heat storage capacity. When the air flows through the heating element, the temperature of the heating element is not likely to fluctuate greatly, so that the matrix part 12 can be fully heated.

[0067] Please refer to Figure 7 and Figure 8 , in some embodiments of the present application, an air vent passage 2411 is formed on the heat storage ceramic 241, and the air vent passage 2411 penetrates through the heat storage ceramic 241 along a preset direction. In this way, during the process of sucking the aerosol product 1, air can pass through the heat storage ceramic 241 through the air vent passage 2411, and the heat of the heat storage ceramic 241 can be fully transferred to the flowing air, so as to heat the downstream matrix part 12 by using the generated hot air flow. In some embodiments of the present application, the number of the air vent passages 2411 can be multiple, so that the heat storage ceramic 241 has a porous structure. In this way, on the one hand, the contact area between the heat storage ceramic 241 and the air is relatively large, and on the other hand, the air flow is relatively smooth during the process of sucking the aerosol product 1.

[0068] Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, along the preset direction, the density of the matrix part 12 gradually increases, so that the density of the matrix part 12 gradually increases. The density of the matrix part 12 is the proportion of the volume of the solid matter part of the matrix part 12 in the total volume. By adjusting the density of the matrix part 12 to adjust the density of the matrix part 12, the processing and manufacturing are relatively convenient.

[0069] Please refer to Figure 1 and Figure 2, in some embodiments of the present application, along a preset direction, the size of the matrix units of the matrix part 12 gradually decreases, so that the density of the matrix part 12 gradually increases. In this way, by adjusting the size of the matrix units to adjust the density of the matrix part 12, the processing and manufacturing are relatively convenient. It can be understood that the smaller the size of the matrix units, the smaller the gaps between the multiple matrix units, and the greater the density of the matrix part 12.

[0070] In this embodiment, the matrix part 12 is formed by the accumulation of matrix units. The matrix units can be in the form of particle structures, strip structures, sheet structures, or filamentous structures, etc. The embodiments of the present application do not limit this. For the particle structure, reference can be made to Figure 1 , Figure 3 and Figure 6 . For the strip structure, please refer to Figure 5 . In some embodiments of the present application, the matrix part 12 can include one of a particle structure, a strip structure, and a filamentous structure, etc., or can include at least two of them. The embodiments of the present application do not limit this. Of course, in some embodiments of the present application, the matrix part 12 may not be formed by the accumulation of matrix units. For example, the matrix part 12 can be in the form of a paste structure, etc.

[0071] Please refer to Figure 1 and Figure 2 . In some embodiments of the present application, the matrix part 12 can include tobacco. In some embodiments of the present application, the matrix part 12 can also include non-tobacco plant materials. Exemplarily, the non-tobacco plant materials can be aromatic plant particles such as fennel, cloves, star anise, or tea leaves, etc., or can be plant fibers impregnated with an atomized liquid, etc.

[0072] Please refer to Figure 1 and Figure 2 . In some embodiments of the present application, the total weight of the tobacco and non-tobacco plant materials in the matrix part 12 for generating aerosol is 0.1 gram to 0.4 grams. In this way, on the one hand, the total amount of aerosol that the matrix part 12 can generate is relatively large, and on the other hand, the matrix part 12 is easily heated sufficiently.

[0073] Please refer to Figure 1 and Figure 2 . In some embodiments of the present application, the matrix part 12 can include at least one of an adhesive, an auxiliary agent, a pore-forming agent, cellulose, essence, nicotine, and nicotine salts. The adhesive can include at least one of carboxymethyl cellulose, sodium alginate, guar gum, and modified starch. The auxiliary agent can include a humectant. The humectant can include at least one of malt oligosaccharide alcohol, D-galacturonic acid, chitosan derivatives, propylene glycol, glycerol, sorbitol, and xylitol. The pore-forming agent can increase the hardness of the matrix part 12 and make the matrix part 12 form pores, etc. The pore-forming agent can include calcium carbonate.

[0074] Please refer toFigure 1 and Figure 2 In some embodiments of the present application, the matrix part 12 includes at least two matrix sub-parts, and the sizes of the matrix units in the same matrix sub-part are the same; along the direction from the center of the matrix part 12 to the outer periphery, the sizes of the matrix units of at least two adjacent matrix sub-parts decrease in sequence, so that the density of the matrix part 12 gradually increases. In this way, the same matrix sub-part uses matrix units with the same size, and different matrix sub-parts use matrix units with different sizes, which can more conveniently form a density gradient of the matrix part 12 and facilitate the processing and manufacturing of the matrix part 12.

[0075] In some embodiments of the present application, along a preset direction, the density of each matrix sub-part gradually increases. In this way, the same matrix sub-part also has a density gradient along the preset direction, which is beneficial to further improving the puff-to-puff consistency of the aerosol product 1.

[0076] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the preset direction is the direction from the center of the matrix part 12 to the outer periphery. The matrix part 12 includes a first matrix sub-part 1201 to an Nth matrix sub-part. The Nth matrix sub-part is coated on the outer peripheral surface of the (N - 1)th matrix sub-part, and the density of the Nth matrix sub-part is greater than that of the (N - 1)th matrix sub-part. In such a structural form, by laminating at least two matrix sub-parts, the matrix part has a density gradient, which is convenient for the processing and manufacturing of the matrix part.

[0077] Please refer to Figure 1 and Figure 2 It can be understood that in the embodiments of the present application, N is an integer greater than 2. Exemplarily, please refer to Figure 2 where N is 3, that is, the matrix part 12 includes a first matrix sub-part 1201, a second matrix sub-part 1202, and a third matrix sub-part 1203.

[0078] It can be understood that in the embodiments of the present application, the densities of the first matrix proton part 1201, the second matrix proton part 1202 and the third matrix proton part 1203 increase in sequence. The induction heating element 15 is arranged inside the first matrix proton part 1201, and the heat generated by the induction heating element 15 is sequentially transferred to the first matrix proton part 1201, the second matrix proton part 1202 and the third matrix proton part 1203. The thermal conductivity of the first matrix proton part 1201 is relatively small. In the initial stage of heating, the first matrix proton part 1201 can quickly accumulate heat, so as to generate aerosol at a relatively large rate. The thermal conductivity of the second matrix proton part 1202 is moderate. After heating for a certain period of time, the first matrix proton part 1201 is largely consumed, and the rate of generating aerosol is small. At this time, the second matrix proton part 1202 has been heated for a certain period of time and can be fully heated, and the rate of generating aerosol is large. The thermal conductivity of the third matrix proton part 1203 is relatively large. After heating for a long time, both the first matrix proton part 1201 and the second matrix proton part 1202 are largely consumed, and the rates of generating aerosol are both small. At this time, the third matrix proton part 1203 has been heated for a long time and can be fully heated, and the rate of generating aerosol is large. In this way, during the whole heating process, the rate of generating aerosol of the aerosol product 1 is relatively large, which is beneficial to improving the puff-to-puff consistency.

[0079] Please refer to Figure 3 and Figure 4 , in some embodiments of the present application, the "predetermined direction" is the direction from the outer periphery of the matrix part 12 towards the center. The matrix part 12 includes at least two matrix proton parts, and the at least two matrix proton parts are sequentially coated, and the density of the matrix proton part located inside is less than the density of the matrix proton part located outside. With such a structural form, by arranging at least two matrix proton parts in a stacked manner, the atomizing matrix has a density gradient, which is convenient for the processing and manufacturing of the atomizing matrix.

[0080] Please refer to Figure 3 and Figure 4 , the embodiments of the present application do not limit the number of matrix proton parts. Exemplarily, referring to Figure 4 , the number of matrix proton parts is four, that is, the matrix part 12 includes a fourth matrix proton part 1204, a fifth matrix proton part 1205, a sixth matrix proton part 1206 and a seventh matrix proton part 1207. The fourth matrix proton part 1204, the fifth matrix proton part 1205, the sixth matrix proton part 1206 and the seventh matrix proton part 1207 are sequentially coated, and the densities increase in sequence.

[0081] It can be understood that in the embodiments of the present application, the matrix part 12 is arranged in the heating cavity surrounded by the heating element, and the heat generated by the heating element is sequentially transferred to the fourth matrix sub - part 1204, the fifth matrix sub - part 1205, the sixth matrix sub - part 1206, and the seventh matrix sub - part 1207. The thermal conductivities of the fourth matrix sub - part 1204, the fifth matrix sub - part 1205, the sixth matrix sub - part 1206, and the seventh matrix sub - part 1207 increase in sequence. In the initial stage of heating, the fourth matrix sub - part 1204 can quickly accumulate heat, so as to generate aerosol at a relatively large rate. The heating rate of the fifth matrix sub - part 1205 is less than that of the fourth matrix sub - part 1204. As time goes by, the fourth matrix sub - part 1204 is consumed in large quantities, and the fifth matrix sub - part 1205 is heated for a certain period of time and can be fully heated, generating aerosol at a relatively large rate. By analogy, along the direction from the outer periphery of the matrix part 12 towards the center, the next matrix sub - part can be fully heated when the previous matrix sub - part is consumed in large quantities, so that the rate of generating aerosol of the aerosol product is relatively large, which is beneficial to improving the puff - to - puff consistency.

[0082] Please refer to Figure 5 and Figure 6 , in some embodiments of the present application, the direction from the filter part 11 to the matrix part 12 is the same as or opposite to the preset direction. The matrix part 12 includes at least two matrix sub - parts, and the two matrix sub - parts are stacked along the first direction y. In such a structural form, by arranging at least two matrix sub - parts in a stacked manner, the atomized matrix has a density gradient, which is convenient for the processing and manufacturing of the atomized matrix.

The eighth matrix sub - part 1208, the ninth matrix sub - part 1209, and the tenth matrix sub - part 1210, the eleventh matrix sub - part 1211, the twelfth matrix sub - part 1212, and the thirteenth matrix sub - part 1213 are arranged in sequence along the first direction y, and the densities increase in sequence. In some other embodiments of the present application, referring to Figure 6, the number of the matrix proton parts is five. The matrix part 12 includes a fourteenth matrix proton part 1214, a fifteenth matrix proton part 1215, a sixteenth matrix proton part 1216, a seventeenth matrix proton part 1217, and an eighteenth matrix proton part 1218.

[0084] Exemplarily, please refer to Figure 5 , Figure 7 and Figure 8 , in some embodiments of the present application, the "preset direction" is the direction from the upstream end to the downstream end of the matrix part 12, that is, the air flow direction from bottom to top as shown in Figure 5 . The hot air heated by the electrothermal ceramic part 24 sequentially passes through the eighth matrix proton part 1208, the ninth matrix proton part 1209, the tenth matrix proton part 1210, the eleventh matrix proton part 1211, the twelfth matrix proton part 1212, and the thirteenth matrix proton part 1213. The thermal conductivity coefficients of the eighth matrix proton part 1208, the ninth matrix proton part 1209, the tenth matrix proton part 1210, the eleventh matrix proton part 1211, the twelfth matrix proton part 1212, and the thirteenth matrix proton part 1213 increase in sequence. In the initial stage of heating, the eighth matrix proton part 1208 can quickly accumulate heat, so as to generate aerosol at a relatively large rate. The heating rate of the ninth matrix proton part 1209 is less than that of the eighth matrix proton part 1208. As time goes by, the eighth matrix proton part 1208 is consumed in large quantities, and the ninth matrix proton part 1209 is heated for a certain period of time and can be fully heated, and the rate of generating aerosol is relatively large. And so on, along the direction from the upstream end to the downstream end of the matrix part 12, the next matrix proton part can be fully heated when the previous matrix proton part is consumed in large quantities, so that the rate of generating aerosol of the aerosol product 1 is relatively large, which is beneficial to improving the puff-to-puff consistency.
