For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0059] As shown in Figure 1 Figure 17 The aerosol generating article provided by the embodiments of the present application comprises:

[0060] The smoking part 1 has a first end and a second end, the directions of the first end and the second end are two ends opposite in the axial direction, and the smoking part 1 is provided with a channel 2 extending in the axial direction.

[0061] The liquid storage part 3 is arranged in the channel 2, and the liquid storage part 3 comprises a porous carrier and a functional medium loaded on the porous carrier.

[0062] The smoking part 1 is hollow, that is, the smoking part 1 is provided with a channel 2 extending in the axial direction, and the channel 2 can be a hollow accommodating space, which can penetrate through the first end and the second end, or only one of the first end and the second end. The porous carrier is selected from porous materials with certain adsorption and capable of being shaped under certain conditions and not releasing toxic and harmful substances after heating, which is not limited here.

[0063] The aerosol generating article provided by the embodiments of the present application reduces the thickness of the smoking part 1 by arranging the channel 2 in the smoking part 1, thereby reducing the heat transfer distance, especially suitable for circumferential heating mode, improving the utilization rate of smoking material of the smoking part 1, and at the same time, the liquid storage part 3 loaded with the functional medium (smoking agent, essence and other substances for enhancing taste) is arranged in the middle, the functional medium of the liquid storage part 3 is heated and volatilized to supplement the amount of smoke or enhance the taste, thereby ensuring the amount of smoke and the taste of the aerosol generating article as a whole.

[0064] In addition, in the aerosol generating article in the related art, the smoking part 1 is filled with tobacco in the form of particles, sheets or filaments. In order to meet the market demand for large amount of smoke, the amount of tobacco is increased to increase the amount of smoke, which increases the cost of tobacco and also increases the suction resistance. However, in the present embodiment, the channel 2 is arranged in the smoking part 1, and the liquid storage part 3 loaded with the functional medium (smoking agent, essence and other substances for enhancing taste) is arranged in the channel 2, so that the functional medium can be volatilized to increase the amount of smoke or enhance the taste. By controlling the structure of the liquid storage part 3 and the functional medium loaded therein, the suction resistance can be adjusted to a certain extent.​

[0065] As Figure 1 - Figure 12 and Figure 14 - Figure 17 In some embodiments, as shown in the figure, the channel 2 extends through both ends of the smoking portion 1 in the axial direction, and the porous carrier has pores that communicate with the first end and the second end of the smoking portion 1.

[0066] The length L1 of the liquid storage portion 3 in the axial direction is less than or equal to the length L2 of the smoking portion 1; and / or, the volume of the functional medium is not greater than 75% of the volume of the porous carrier.

[0067] In this embodiment, the channel 2 extends through the smoking portion 1 in the axial direction, and the porous carrier is arranged in the channel 2. The porous carrier has pores that communicate with the first end of the smoking portion 1 and the second end of the smoking portion 1, so that both ends of the porous carrier are air-permeable, which facilitates the adjustment of the draw resistance by controlling the structure of the liquid storage portion 3 and the functional medium loaded thereon. The length of the porous carrier can be adjusted to adjust the draw resistance of the aerosol generating article during smoking. The longer the porous carrier, the greater the draw resistance, and the shorter the porous carrier, the smaller the draw resistance. In addition, under the same conditions, the greater the amount of functional medium loaded on the porous carrier, the greater the draw resistance, and vice versa.

[0068] In this embodiment, the length L1 of the liquid storage portion 3 in the axial direction is less than or equal to the length L2 of the smoking portion 1, that is, the length L1 of the porous carrier in the axial direction is less than or equal to the length L2 of the smoking portion 1. In addition, when the functional medium is not loaded on the porous carrier, the volume of the functional medium is not greater than 75% of the volume of the porous carrier, that is, the added amount of the functional medium is not more than 75% of the volume of the empty porous carrier, thereby preventing the draw resistance from being too large.

[0069] In some embodiments, the smoking portion 1 is columnar, the length L1 of the smoking portion 1 is 2-20 mm, and the diameter of the smoking portion 1 is 5-10 mm; the channel 2 is cylindrical, and the diameter of the channel 2 is less than 6.5 mm. Thus, the utilization rate of the smoking portion 1 is ensured.

[0070] In some embodiments, the porous carrier is liquid storage cotton, and / or the functional medium is selected from at least one of flavoring and smoking agent.

[0071] The liquid storage cotton is made of fibrous material and has a three-dimensional network structure with high porosity, which can absorb liquid and maintain the stability of the liquid, while preventing liquid leakage or penetration.

[0072] Fragrances can be natural or synthetic, or a mixture of both, and are used to give products a specific smell or flavor. When circumferential heating is used, fragrances with lower boiling points can be selected so that even if they are placed in channel 2, the temperature of the liquid storage section 3 can still reach the temperature required for fragrance release.

[0073] Smoke-generating agents can be polyols, such as glycerol (glycerol), propylene glycol, etc.

[0074] In some embodiments, the aerosol generating article further includes an induction heating element 4, which is disposed on the smoke generating section 1.

[0075] In this embodiment, in conjunction with a magnetic induction heating appliance, the induction heating element 4 generates heat through induction. Since the induction heating element 4 is in close contact with the smoke-generating part 1, the utilization rate of the smoke-generating part 1 is further improved.

[0076] like Figure 1 As shown, in some embodiments, the induction heating element 4 is a strip-shaped structure, and the induction heating element 4 is spirally wound around the outer peripheral surface of the smoke-generating part 1.

[0077] In this embodiment, the induction heating element 4 on the outer peripheral surface directly heats the smoke-generating section 1. The temperature generated at this time is relatively high, which can effectively bake out the aroma. The functional medium inside the channel 2 absorbs the heat transferred from the smoke-generating section 1. At this time, the heat generated by the induction heating element 4 has been partially absorbed by the smoke-generating section 1 and has been attenuated to a certain extent by the time it reaches the liquid storage section 3. The flavor and other substances in the liquid storage section 3 can be slowly released at a lower temperature. Overall, the flavor consistency of the aerosol-generated product is improved, and the smoke-generating section 1 can also be released relatively well. The flavor and other substances in the liquid storage section 3 can still maintain a strong flavor characteristic in the later stage of the consumer's inhalation, which to a certain extent masks the off-flavors and burnt taste generated by the smoke-generating section 1 at high temperature in the later stage, thus optimizing the consumer's experience in the later stage.

[0078] like Figure 3 As shown, in some embodiments, the induction heating element 4 is a strip-shaped sheet structure, the smoke-generating part 1 is columnar, and the axial direction has a through channel 2; the induction heating element 4 is a strip-shaped sheet element, the induction heating element 4 passes through the channel 2, and extends axially on the outer peripheral surface of the smoke-generating part 1 and the inner wall surface of the channel 2, and extends radially at the first end and the second end; the induction heating elements 4 are a plurality of those arranged circumferentially at intervals in the smoke-generating part 1;

[0079] In this embodiment, the induction heating element 4 heats the smoke-generating part 1 on both the outer peripheral surface of the smoke-generating part 1 and the inner wall surface of the channel 2, resulting in more thorough heating of the smoke-generating part 1. Furthermore, since the induction heating element 4 has a larger heating area for the smoke-generating part 1, the preheating time before inhalation can be shortened, and the flavor becomes richer. The functional medium in the liquid storage part 3 within the channel 2 can further enhance the amount of smoke or enhance the characteristic flavor after heating.

[0080] like Figure 5 As shown, in some embodiments, the smoke-generating part 1 is formed by winding a smoke-generating matrix sheet 13, and when unfolded, the induction heating element 4 extends along the diagonal direction of the smoke-generating matrix sheet 13.

[0081] In this embodiment, the induction heating elements 4 are more evenly distributed in the smoke-generating section 1, thus heating the smoke-generating section 1 more thoroughly. Simultaneously, because the heating area of ​​the smoke-generating section 1 by the induction heating elements 4 is larger, the preheating time before inhalation can be shortened, and the flavor is more intense. Furthermore, because a portion of the induction heating element 4 (e.g., the inner layer) is closer to the liquid storage section 3 in the channel 2, the heat reaching the liquid storage section 3 is higher, resulting in more complete evaporation of the functional medium in the liquid storage section 3.

[0082] In some embodiments, the smoke-generating matrix sheet 13 is rectangular when unfolded, and after being rolled into a smoke-generating part 1, the smoke-generating part 1 is a cylindrical shape with a diameter of 5-10 mm, preferably a cylindrical shape with a diameter of 6-7.5 mm.

[0083] This ensures the utilization rate of the smoke-generating section 1.

[0084] like Figure 6 As shown, in some embodiments, the smoke-generating part 1 includes a smoke-generating column 11 and a first smoke-generating plate 12; the induction heating element 4 is embedded in the first smoke-generating plate 12, and the first smoke-generating plate 12 wraps around the outer peripheral surface of the smoke-generating column 11;

[0085] In this embodiment, the induction heating element 4 directly heats the smoke-generating section 1, resulting in a relatively high temperature that effectively bakes out the aroma. The functional medium inside the channel 2 absorbs the heat transferred from the smoke-generating section 1. Since some of the heat generated by the induction heating element 4 is absorbed by the smoke-generating section 1, it has already attenuated to some extent by the time it reaches the liquid storage section 3. The flavorings in the liquid storage section 3 can be slowly released at a lower temperature. Overall, the flavor consistency of the aerosol-generated product is improved, and the smoke-generating section 1 can be released more completely. The flavorings in the liquid storage section 3 can still maintain a strong flavor characteristic in the later stages of the consumer's inhalation, which to some extent masks the off-flavors and burnt taste generated by the smoke-generating section 1 at high temperatures, thus optimizing the consumer's experience in the later stages. At the same time, the induction heating element 4 is embedded in the first smoke-generating plate 12 and then wraps around the smoke-generating column 11, making the structure more stable.

[0086] like Figure 7As shown in some embodiments, the smoking portion 1 comprises a smoking substrate sheet 13 wound to form a columnar structure, a plurality of smoking substrate strips 14, the plurality of smoking substrate strips 14 are sequentially and spacedly arranged on the smoking substrate sheet 13, and the induction heating element 4 extends along the diagonal direction of the smoking substrate sheet 13; in this embodiment, the plurality of smoking substrate strips 14 create a certain air passage inside the smoking portion 1, which plays a role in adjusting the resistance, avoiding the situation that the smoking substrate sheet 13 is wound too tightly, resulting in too large resistance of the aerosol generating article.

[0087] In some embodiments, the smoking substrate sheet 13 is rectangular when unfolded, and after being wound into the smoking portion 1, the smoking portion 1 is in the shape of a roll with a diameter of 5-10 mm, preferably in the shape of a roll with a diameter of 6-7.5 mm.

[0088] Further, the utilization rate of the smoking portion 1 is ensured.

[0089] As shown in some embodiments, Figure 8 - Figure 9 As shown in some embodiments, the smoking portion 1 comprises a smoking substrate sheet 13 wound to form a columnar structure, a plurality of smoking particles, the plurality of smoking particles 15 are distributed on the smoking substrate sheet 13, and the induction heating element 4 extends along the diagonal direction of the smoking substrate sheet 13. The smoking particles 15 can be distributed in order or randomly, and the smoking particles 15 can be particles of equal size or particles of different sizes. In this embodiment, the plurality of smoking particles 15 create a certain air passage inside the smoking portion 1, which plays a role in adjusting the resistance, avoiding the situation that the smoking substrate sheet 13 is wound too tightly, resulting in too large resistance of the aerosol generating article.

[0090] In some embodiments, the smoking substrate sheet 13 is rectangular when unfolded, and after being wound into the smoking portion 1, the smoking portion 1 is in the shape of a roll with a diameter of 5-10 mm, preferably in the shape of a roll with a diameter of 6-7.5 mm.

[0091] Further, the utilization rate of the smoking portion 1 is ensured.

[0092] As shown in some embodiments, Figure 2 and Figure 15 - Figure 16 As shown in some embodiments, the outer circumferential surface of the liquid storage portion 3 abuts against the inner wall surface of the channel 2.

[0093] Embedding the liquid storage portion 3 in the channel 2 can increase the friction between the liquid storage portion 3 and the inner wall surface of the channel 2, thereby achieving the effect of preventing the liquid storage portion 3 from falling out of the channel 2.

[0094] In some embodiments, as shown in Figure 11 , wherein the channel extends through both ends of the smoking portion in the axial direction, the inner wall surface of the channel 2 is provided with a groove 5 extending through the smoking portion 1 in the axial direction; or, as shown inFigure 10 As shown, the outer peripheral surface of the smoke-generating part 1 is provided with a groove 5 that extends axially and penetrates the smoke-generating part 1.

[0095] like Figure 10 - Figure 11 As shown, in some embodiments, the grooves 5 have a plurality of grooves evenly distributed circumferentially. The channel 2 has a gear-shaped cross-section perpendicular to the axial direction.

[0096] In these embodiments, the design of channel 2 and groove 5 can form an air passage through the smoke-generating part, which can reduce the suction resistance when using aerosol-generating articles.

[0097] like Figure 12 As shown, in some embodiments, the induction heating element 4 is disposed on the smoke-generating part 1; the induction heating element 4 is a strip-shaped sheet structure, the smoke-generating part 1 is columnar, and the axial direction has a through channel 2; the induction heating element 4 is a strip-shaped sheet element, the induction heating element 4 passes through the channel 2, and simultaneously extends axially on the outer peripheral surface of the smoke-generating part 1, extends axially on the inner wall surface of the channel 2 and is embedded in the groove 5, and extends radially at the first end and the second end; the induction heating elements 4 are a plurality of circumferentially spaced in the smoke-generating part 1.

[0098] In this embodiment, the induction heating element 4 heats the smoke-generating part 1 simultaneously on both the outer peripheral surface of the smoke-generating part 1 and the inner wall surface of the channel 2, resulting in more thorough heating of the smoke-generating part 1. Furthermore, because the induction heating element 4 heats a larger area of ​​the smoke-generating part 1, the preheating time before inhalation can be shortened, and the flavor is more intense. The functional medium in the liquid storage part 3 within the channel 2 can further enhance the amount of smoke or enhance characteristic flavors after heating. The induction heating element 4 is embedded in the groove 5, ensuring closer contact with the smoke-generating part 1, increasing heat transfer efficiency, and providing greater stability.

[0099] In some embodiments, such as Figure 13 As shown, the first end is the end near the smoke outlet of the aerosol generating product, and the second end is opposite to the first end; the channel 2 extends from the interior of the smoke generating part 1 to the first end, and the channel 2 does not extend to the second end.

[0100] In this embodiment, under the action of gravity, the liquid storage part 3 may fall out of the channel 2, or some of the functional medium may detach from the porous carrier. The second end plays a supporting role, and the functional medium that detaches from the porous carrier is absorbed by the smoke-generating part 1 at the bottom, which can effectively avoid the problem of resource waste.

[0101] In some embodiments, such as Figure 14As shown, the channel 2 extends through the smoke-generating part 1, and the radial cross-sectional area of ​​the channel 2 gradually decreases from the second end to the first end.

[0102] In this embodiment, the inner wall of the channel 2 is an inclined surface, which supports the liquid storage part 3 and prevents the liquid storage part 3 from falling out of the channel 2 due to gravity.

[0103] like Figure 15 - Figure 16 As shown, in some embodiments, it further includes:

[0104] An induction heating element 4 is disposed on the liquid storage section 3.

[0105] In some embodiments, such as Figure 15 As shown, the induction heating element 4 has a strip-shaped structure and is spirally wound around the outer peripheral surface of the liquid storage part 3;

[0106] In some embodiments, such as Figure 16 - Figure 17 As shown, the liquid storage section 3 encloses the second smoke-generating sheet 6, the induction heating element 4 is embedded in the second smoke-generating sheet 6, and the tobacco sheet is wrapped around the outer peripheral surface of the smoke-generating section 1.

[0107] This structural design allows heat to be transferred both outwards and inwards simultaneously. The outward transfer heat generates smoke, while the inward transfer heat heats the liquid storage section 3.

[0108] In some embodiments, the smoke-generating part 1 includes tobacco material, but is not limited to tobacco material.

[0109] In some embodiments, the smoke-generating part 1 is cylindrical, the channel 2 is located at the center of the smoke-generating part 1 and has a circular cross-section, and the liquid storage component is cylindrical.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
