Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of aerosol generation for non-combustion heating, and particularly to an aerosol generation article and an aerosol generation system. Background Art

[0002] During use, tobacco products (such as cigarettes, cigars, etc.) burn tobacco to produce tobacco smoke. People have tried to replace these tobacco-burning products by manufacturing products that release compounds without burning.

[0003] A typical tobacco product includes a continuously arranged smoke-generating matrix. During suction, the smoke generated by the smoke-generating matrix all passes through the same airway and is directed towards the mouthpiece. However, the smoke is likely to condense in the airway to form condensate. As the condensate in the airway increases, it will affect the smoke generation of the tobacco product and the taste of the tobacco product, thereby reducing the user experience.

[0070] Reference may be made to Figure 1 , an embodiment of the present application provides an aerosol generating system, which includes an aerosol generating device and an aerosol generating article 1, and the aerosol generating device 2 is used to provide energy to enable the aerosol generating article 1 to generate an aerosol.

[0071] Reference may be made to Figures 1 - 4 , an embodiment of the present application provides an aerosol generating article 1, which includes a housing 12 and an aerosol-forming substrate 11 held in the housing 12. The aerosol-forming substrate 11 is capable of generating a volatile substance, and the volatile substance can form an aerosol after combining with air.

[0072] In one embodiment, when heated, the aerosol-forming substrate 11 is capable of releasing a volatile compound that can form an aerosol. In one embodiment, at room temperature, the aerosol-forming substrate 11 is capable of releasing a volatile compound that can form an aerosol. In one embodiment, the aerosol generating article 1 can be removably connected to the aerosol generating device 2. The aerosol generating article 1 can be disposable or reusable.

[0073] The aerosol-forming substrate 11 may include a solid aerosol-forming substrate. The solid aerosol-forming substrate may include a tobacco-containing material, and the tobacco-containing material contains a volatile tobacco flavor compound released from the aerosol-forming substrate when heated. The solid aerosol-forming substrate may include a non-tobacco material. The solid aerosol-forming substrate may include a tobacco-containing material and a non-tobacco material.

[0074] The aerosol-forming substrate 11 may include a liquid aerosol-forming substrate. The liquid aerosol-forming substrate may contain a liquid of a tobacco-containing substance containing a volatile tobacco flavor component, and may also be a liquid containing a non-tobacco substance. The liquid aerosol-forming substrate may contain water, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture, etc. The fragrance may include areca extract, menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent may include components that can provide various scents or flavors to the user. The vitamin mixture may be a mixture mixed with at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto.

[0075] In such asFigure 1 In the illustrated embodiment, the aerosol generating device 2 includes a receiving chamber 21 into which the aerosol generating article 1 can be received. The aerosol generating device 2 further includes a mouthpiece 22 communicating with the receiving chamber 21, and the mouthpiece 22 can be held by the user between the lips. The user sucks the aerosol generated by the aerosol generating article 1 by sucking on the mouthpiece 22.

[0076] Reference may be made to Figure 1 In an embodiment of the present application, the housing 12 has an air inlet end 123, an air outlet end 124, and an air passage communicating the air inlet end 123 and the air outlet end 124. During suction, air flows into the interior of the housing 12 through the air inlet end 123, then flows inside the housing 12 along the air passage inside the housing 12, and finally flows out of the housing 12 through the air outlet end 124. The volatile substances generated by the aerosol forming substrate 11 can enter the air passage and combine with the air in the air passage to form an aerosol, and then the aerosol flows along the air passage towards the air outlet end 124.

[0077] To prevent the condensate formed by the condensation of the aerosol from accumulating in the air passage, there can be multiple air passages and the multiple air passages are independent of each other, such that one air passage only transmits the aerosol formed based on a part of the aerosol forming substrate 11, and the aerosol formed by the remaining aerosol forming substrate 11 is transmitted through other air passages. Thereby, the total amount of aerosol transmitted through a single air passage can be reduced, and further the amount of condensate accumulated in that single air passage can be reduced. Therefore, it can prevent the condensate from affecting the generation of volatile substances by the aerosol forming substrate 11 that has not yet generated volatile substances or that can still continue to generate volatile substances due to the large amount, which helps to ensure that the aerosol forming substrate 11 is fully heated and generates volatile substances sufficiently or hierarchically according to the preset, and thus can ensure the taste.

[0078] Specifically, reference may be made to Figure 4 The air passage at least includes a first air passage 125 and a second air passage 126. The first air passage 125 and the second air passage 126 independently communicate with the air inlet end 123 and the air outlet end 124 of the housing 12 respectively. The aerosol forming substrate 11 at least includes a first aerosol forming substrate 111 and a second aerosol forming substrate 112. The volatile substances generated by the first aerosol forming substrate 111 and the second aerosol forming substrate 112 enter the first air passage 125 and the second air passage 126 respectively. In other words, the first air passage 125 can receive and transmit the volatile substances and aerosol generated by the first aerosol forming substrate 111 to the air outlet end 124, and the second air passage 126 can receive and transmit the volatile substances and aerosol generated by the second aerosol forming substrate 112 to the air outlet end 124.

[0079] In one embodiment, the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 exist independently of each other. In this embodiment, the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 may be exactly the same, or the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 may be different. For example, they may have different flavors, different components, different shapes, or different sizes, etc.

[0080] It should be noted that in other embodiments, the first aerosol-forming substrate and the second aerosol-forming substrate are not independent of each other, but different parts of the same aerosol-forming substrate.

[0081] In one embodiment, reference may be made to Figure 2 , the air inlet end 123 of the housing 12 includes a first air inlet 1231 and a second air inlet 1232 that are independent of each other. Therefore, the first air inlet 1231 and the second air inlet 1232 are spaced apart from each other. Among them, the first air inlet 1231 communicates with the first air passage 125, and the second air inlet 1232 communicates with the second air passage 1232. During suction, air enters the first air passage 125 and the second air passage 126 through the first air inlet 1231 and the second air inlet 1232 respectively.

[0082] It should be noted that in other embodiments, the air inlet end of the housing includes a common air inlet, and the common air inlet communicates with the first air passage and the second air passage at the same time. During suction, air enters the common air inlet, and then branches out and flows into the first air passage and the second air passage respectively.

[0083] In one embodiment, reference may be made to Figure 3 , the air outlet end 124 of the housing 12 includes a first air outlet 1241 and a second air outlet 1242 that are independent of each other. Therefore, the first air outlet 1241 and the second air outlet 1242 are spaced apart from each other. Among them, the first air outlet 1241 communicates with the first air passage 125, and the second air outlet 1242 communicates with the second air passage 126. During suction, the aerosol in the first air passage 125 flows out of the housing 12 through the first air outlet 1241, and the aerosol in the second air passage 126 flows out of the housing 12 through the second air outlet 1242.

[0084] It should be noted that in other embodiments, the air outlet end of the housing includes a common air outlet, and the common air outlet communicates with the first air passage and the second air passage at the same time. During suction, the aerosol in the first air passage flows out of the housing through the common air outlet, and the aerosol in the second air passage flows out of the housing through the common air outlet.

[0085] To facilitate the arrangement of the aerosol-forming substrate 11 inside the housing 12 and to facilitate the layout of the mutually independent first airway 125 and second airway 126 inside the housing 12, the housing 12 can be divided into at least two parts. Specifically, the housing 12 includes a first housing 121 and a second housing 122, the first housing 121 and the second housing 122 are connected to each other, and the first airway 125 and the second airway 126 are formed between the first housing 121 and the second housing 122. To ensure that the gas in the first airway 125 and the second airway 126 does not leak through the connection between the first housing 121 and the second housing 122, the connection between the first housing 121 and the second housing 122 can be a sealed connection. For example, there can be a sealing adhesive between the first housing 121 and the second housing 122, or for example, the first housing 121 and the second housing 122 can be tightly fitted or have an interference fit.

[0086] In one embodiment, reference can be made to Figures 4 - 9 , the first housing 121 includes a first base 1211, the second housing 122 includes a second base 1221 spaced from the first base 1211, and the first airway 125 and the second airway 126 are located between the first base 1211 and the second base 1221. The housing 12 further includes a first convex beam 127 extending from the intake end 125 to the outlet end 126. The first airway 125 and the second airway 126 are located on opposite sides of the first convex beam 127. The first convex beam 127 spaces the first airway 125 and the second airway 126 apart and makes them mutually independent, and can prevent the airflows in the first airway 125 and the second airway 126 from converging. The first convex beam 127 can define a partial boundary of the first airway 125. The first convex beam 127 can define a partial boundary of the second airway 126.

[0087] In one embodiment, reference can be made to Figure 4 , Figures 7 - 9 , the housing 12 further includes a second convex beam 128 extending from the intake end 123 to the outlet end 124. The second convex beam 128 connects the first base 1211 and the second base 1221, and the first airway 125 is located between the second convex beam 128 and the first convex beam 127. The second convex beam 128 can define a partial boundary of the first airway 125. The second convex beam 128 and the first convex beam 127 can be parallel to each other.

[0088] In one embodiment, reference can be made to Figure 4 , Figures 7 - 9 , the housing 12 further includes a third convex beam 129 extending from the intake end 123 to the outlet end 124. The third convex beam 129 connects the first base 1211 and the second base 1221, and the second airway 126 is located between the third convex beam 129 and the first convex beam 127. The third convex beam 129 can define a partial boundary of the second airway 126. The third convex beam 129 and the first convex beam 127 can be parallel to each other.

[0089] In one embodiment, reference may be made to Figures 5 - 7 , the housing 12 further includes a third connecting wall 1214. After the first housing 121 and the second housing 122 are connected to each other, the second convex beam 128 may interfere with the third connecting wall 1214 in the width direction of the housing 12. For example, the second convex beam 128 may be squeezed or interference-fitted with the third connecting wall 1214 in the width direction of the housing 12. The mutual force generated by the interference helps the first housing 121 and the second housing 122 to remain connected.

[0090] In one embodiment, the third connecting wall 1214 extends from the air inlet end 123 to the air outlet end 124. The third connecting wall 1214 connects the first base body 1211 and the second base body 1221. The first air passage 125 is located between the third connecting wall 1214 and the first convex beam 127.

[0091] In one embodiment, reference may be made to Figures 5 - 7 , the housing 12 further includes a fourth connecting wall 1215. After the first housing 121 and the second housing 122 are connected to each other, the third convex beam 129 may interfere with the fourth connecting wall 1215 in the width direction of the housing 12. For example, the third convex beam 129 may be squeezed or interference-fitted with the fourth connecting wall 1215 in the width direction of the housing 12. The mutual force generated by the interference helps the first housing 121 and the second housing 122 to remain connected.

[0092] In one embodiment, the fourth connecting wall 1215 extends from the air inlet end 123 to the air outlet end 124. The fourth connecting wall 1215 connects the first base body 1211 and the second base body 1221. The second air passage 126 is located between the fourth connecting wall 1215 and the first convex beam 127.

[0093] In one embodiment, the housing 12 includes both the second convex beam 128 and the fourth connecting wall 1215. Among them, one of the first housing 121 and the second housing 122 includes the second convex beam 128, and the other includes the fourth connecting wall 1215. In the width direction of the housing 12, the second convex beam 128 and the fourth connecting wall 1215 are spaced apart from each other, and both are located on opposite sides of the first convex beam 127.

[0094] Alternatively, one of the first housing 121 and the second housing 122 includes both the second convex beam 128 and the fourth connecting wall 1215, and the second convex beam 128 and the fourth connecting wall 1215 are located on opposite sides of the first convex beam 127.

[0095] In one embodiment, the housing 12 includes both the third convex beam 129 and the third connecting wall 1214.

[0096] Wherein, one of the first housing 121 and the second housing 122 includes a third convex beam 129, and the other includes a third connecting wall 1214. In the width direction of the housing 12, the third convex beam 129 and the third connecting wall 1214 are spaced apart from each other, and both are located on opposite sides of the first convex beam 127.

[0097] Alternatively, one of the first housing 121 and the second housing 122 simultaneously includes a third convex beam 129 and a third connecting wall 1214, and the third convex beam 129 and the third connecting wall 1214 are located on opposite sides of the first convex beam 127.

[0098] In one embodiment, the housing 121 simultaneously includes a first convex beam 127, a second convex beam 18, and a third convex beam 129. The first convex beam 127, the second convex beam 18, and the third convex beam 129 are spaced apart from each other in the width direction of the housing 12. Among them, the first convex beam 127, the second convex beam 18, and the third convex beam 129 can be arranged parallel to each other in pairs.

[0099] In one embodiment, the housing 121 simultaneously includes a third connecting wall 1214 and a fourth connecting wall 1215. The fourth connecting wall 1215 is spaced apart from the third connecting wall 1214 in the width direction of the housing 12. Among them, the fourth connecting wall 1215 can be arranged parallel to the third connecting wall 1214.

[0100] In the embodiment as Figure 8 and Figure 9 shown, the first convex beam 127 is a component of the first housing 121. The first convex beam 127 can be vertically connected to the first base 1211, and the first convex beam 127 can be integrally formed with the first base 1211, such as by integral injection molding. After the first housing 121 and the second housing 122 are hermetically connected to each other, the first convex beam 127 tightly abuts against the second base 1221, or there is a sealing adhesive between the first convex beam 127 and the second base 1221, so that the connection between the first convex beam 127 and the second base 1221 is a hermetic connection.

[0101] In the embodiment as Figures 4 - 7 shown, the first convex beam 127 is a component of the second housing 122. The first convex beam 127 can be vertically connected to the second base 1221, and the first convex beam 127 can be integrally formed with the second base 1221, such as by integral injection molding. After the first housing 121 and the second housing 122 are hermetically connected to each other, the first convex beam 127 tightly abuts against the first base 1211, or there is a sealing adhesive between the first convex beam 127 and the first base 1211, so that the connection between the first convex beam 127 and the first base 1211 is a hermetic connection.

[0113] The same heating element 13 can be used to heat the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 simultaneously.

[0116] The first heating element 131 can form at least a partial carrier of the first aerosol-forming substrate 111 and can support at least a part of the first aerosol-forming substrate 111. For example, the first aerosol-forming substrate 111 can be coated on the first heating element 131.

The heat-insulating material refers to a material with a thermal conductivity less than or equal to 40 W / (m·K) at 23°C and 50% relative humidity. Preferably, the thermal conductivity of the heat-insulating material used in this application may be less than or equal to 10 W / (m·K), for example, less than or equal to 1 W / (m·K).

Among them, the AEK-based materials include PEEK, PEKK, PEKEKK, or PEK materials.

[0121] To reduce the mutual influence between the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 during operation, there is a heat-insulating material between the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112. For example, at least a part of the first aerosol-forming substrate 111 and at least a part of the second aerosol-forming substrate 112 are respectively held in the first receiving groove 1216 and the second receiving groove 1217 of the first housing 121, where the first housing 121 is made of a heat-insulating material.

[0122] To reduce the influence of the first heating element 131 during operation on the second aerosol-forming substrate 112, and to reduce the influence of the second heating element 132 during operation on the first aerosol-forming substrate 111, a heat-insulating material may be provided between the first heating element 131 and the second heating element 132. Among them, providing a heat-insulating material between the first heating element 131 and the second heating element 132 includes: the first heating element 131 and the second heating element 132 are spaced apart by the heat-insulating material, or the first heating element 131 and the second heating element 132 may be disposed at different positions of the heat-insulating material. The first heating element 131 and the second heating element 132 being disposed at different positions of the heat-insulating material includes: the first heating element 131 and the second heating element 132 are disposed at different positions of the same heat-insulating material, or the first heating element 131 and the second heating element 132 are disposed on heat-insulating materials with different positions.

[0123] In one embodiment, the first heating element 131 and the second heating element 132 are respectively held in the first receiving groove 1216 and the second receiving groove 1217 of the first housing 121, wherein the first housing 121 is made of a heat-insulating material.

[0124] In one embodiment, reference may be made to Figures 5 - 9 , there are multiple first aerosol-forming substrates 111, and the multiple first aerosol-forming substrates 111 may be spaced apart from each other in pairs. There may be a heat-insulating material between any two first aerosol-forming substrates 111, or any two first aerosol-forming substrates 111 are disposed at different positions of the heat-insulating material.

[0125] There may be multiple first receiving grooves 1216, and the multiple first aerosol-forming substrates 111 may be disposed in one-to-one correspondence with the multiple first receiving grooves 1216, so that each first receiving groove 1216 can accommodate one first aerosol-forming substrate 111.

[0126] There may be multiple first heating elements 131, and the multiple first aerosol-forming substrates 111 may be disposed in one-to-one correspondence with the multiple first heating elements 131, so that each first heating element 131 can only heat one first aerosol-forming substrate 111. Among them, there may be a heat-insulating material between any two first heating elements 131, or any two first heating elements 131 are disposed at different positions of the heat-insulating material.

[0127] In one embodiment, reference may be made to Figures 5 - 9 , there are multiple second aerosol-forming substrates 112, and the multiple second aerosol-forming substrates 112 may be spaced apart from each other in pairs. There may be a heat-insulating material between any two second aerosol-forming substrates 112, or any two second aerosol-forming substrates 112 are disposed at different positions of the heat-insulating material.

[0128] There may be a plurality of second receiving grooves 1217, and a plurality of second aerosol-forming substrates 112 may be provided in one-to-one correspondence with the plurality of second receiving grooves 1217, so that each second receiving groove 1217 may accommodate a second aerosol-forming substrate 112.

[0129] There may be a plurality of second heating elements 132, and a plurality of second aerosol-forming substrates 112 may be provided in one-to-one correspondence with the plurality of second heating elements 132, so that each second heating element 132 may only heat one second aerosol-forming substrate 112. Among them, there may be a heat-insulating material between any two second heating elements 132, or any two second heating elements 132 are arranged at different positions of the heat-insulating material.

[0130] In one embodiment, the sum of the numbers of the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 is equal to the total number of preset puffs of the aerosol-generating article 1. For example, if the total number of preset puffs of the aerosol-generating article 1 is 6 puffs, the sum of the numbers of the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 may be equal to 6. By setting, the aerosol formed by the volatile substances generated by a single first aerosol-forming substrate 111 or a single second aerosol-forming substrate 112 can meet the requirements of one puff. Therefore, heating each first aerosol-forming substrate 111 and each second aerosol-forming substrate 112 independently in sequence can ensure the consistency of the fullness of each puff.

[0131] The numbers of the first aerosol-forming substrate 111 and the second aerosol-forming substrate 112 may be equal, or may not be equal.

[0132] It should be noted that in other embodiments, a plurality of first aerosol-forming substrates may be heated simultaneously so that the plurality of first aerosol-forming substrates generate volatile substances simultaneously. Or at least one first aerosol-forming substrate and at least one second aerosol-forming substrate may be heated simultaneously.

[0133] In one embodiment, the heating element 13 includes a susceptor that can generate heat in a changing magnetic field. Therefore, there is no need to use a wire to electrically connect the heating element 13 in the aerosol-generating article 1 to the power supply component in the aerosol-generating device 2, which helps to remove the aerosol-generating article 1 from the aerosol-generating device 2 to replace a new aerosol-generating article 1.

[0134] The susceptor may include metal or carbon. In one embodiment, the susceptor may include a ferromagnetic material, such as ferrite, ferromagnetic steel or stainless steel. In one embodiment, the susceptor includes a nickel-iron alloy. In one embodiment, the susceptor includes a 400 series stainless steel, and the 400 series stainless steel includes grade 410 or grade 420 or grade 430 stainless steel.

[0135] The first heating element 131 may include a susceptor, and the second heating element 132 may include a susceptor. The first heating element 131 and the second heating element 132 may be the same. For example, both may have the same material, the same resistivity, the same magnetic permeability, or the same dimensions. Of course, the first heating element 131 and the second heating element 132 may not be the same.

[0136] Based on this, reference may be made to Figure 10 , the aerosol generating device 2 includes a magnetic field generator 23. The magnetic field generator 23 is electrically connected to a power supply component in the aerosol generating device 2. The power supply component is used to provide a varying current to the magnetic field generator 23 so that the magnetic field generator 23 generates a varying magnetic field. In one embodiment, the magnetic field generator 23 is capable of generating a varying magnetic field between 1 and 30 MHz, for example, between 2 and 10 MHz, for example, between 5 and 7 MHz.

[0137] When the aerosol generating article 1 is engaged with the receiving chamber 21 of the aerosol generating device 2, the corresponding susceptor in the aerosol generating article 1 is within the magnetic field coverage of the corresponding magnetic field generator 23.

[0138] In one embodiment, the magnetic field generator 23 includes a spiral coil. In the embodiment as shown in Figure 10 , the magnetic field generator 23 includes a disk coil.

[0139] In one embodiment, reference may be made to Figure 10 , the number of the magnetic field generators 23 is plural, and the plural magnetic field generators 23 are arranged in one-to-one correspondence with the first heating element 131 and the second heating element 132, so that when one magnetic field generator 23 generates a varying magnetic field, only one heating element can generate heat.

[0140] To reduce the processing cost, reference may be made to Figure 8 and Figure 9 , the first housing 121 or the second housing 122 is configured as a sheet with a uniform thickness. For example, the second housing 122 is configured as a sheet with a uniform thickness. Each of the above-mentioned receiving grooves, each rib, each air passage, or each connecting wall is formed on the first housing 121, so that only the first housing 121 needs to be designed with a more complex mold, thereby reducing the mold opening cost.

[0141] It should be noted that it is optional rather than necessary for the first housing 121 or the second housing 122 to be configured as a sheet with a uniform thickness. In the case of 5- Figure 7In the illustrated embodiment, a first receiving groove 1216 and a second receiving groove 1217 are formed on a first base body 1211 of a first housing 121, so that a first aerosol-forming substrate 111 and a second aerosol-forming substrate 112 can be held on the first housing 121. A first convex beam 127, a second convex beam 128, and a third convex beam 129 are formed on a second base body 1221 of a second housing 122, such that a first air passage 125 and a second air passage 127 are formed on the second housing 122. Providing convex beams on the second base body 1221 helps to increase the strength of the second base body 1221 and can prevent the second housing 122 from deforming during the combination of the first housing 121 and the second housing 122.

[0142] In one embodiment, reference may be made to Figure 2 and Figure 3 , the housing 12 is configured to be flat, and its width is greater than twice its thickness. Reference may be made to Figures 6 - 9 , the first aerosol-forming substrate 111 may be configured to be sheet-shaped, and the second aerosol-forming substrate 112 may be configured to be sheet-shaped to reduce the thickness of the housing 12.

[0143] In one embodiment, reference may be made to Figure 2 and Figure 3 , the housing 12 has a non-centrally symmetric shape, and the direction in which the housing 12 is assembled into the aerosol generating device 2 is determined by the non-centrally symmetric shape of the housing 12. In the embodiments shown in Figure 2 and Figure 3 , the housing 12 has an anti-fooling structure 14, and the anti-fooling structure 14 can make the housing 12 approximately a rectangle missing a corner, or make the housing 12 other non-centrally symmetric shapes.

[0144] To ensure that the aerosol in the first air passage 125 is not overly diluted when the first aerosol-forming substrate 111 is working and make the concentration of the aerosol in the first air passage 125 meet the preset requirements, the first air passage 125 can have a smaller ventilation volume. Specifically, in one example, the ventilation cross-sectional area of the first air passage 125 is less than or equal to 4 mm 2 , for example, about 2.2 mm 2 ; in one example, in the thickness direction of the housing 12, the size of the first air passage 125 is less than or equal to 0.5 mm, for example, about 0.35 mm; in one example, in the width direction of the housing 12, the size of the first air passage 125 is less than or equal to 10 mm, for example, about 6.3 mm. In the embodiments shown in Figure 7 and Figure 9In the illustrated embodiment, in the thickness direction of the housing 12, the size of the first air passage 125 is related to the depth at which the convex beam protrudes towards the first housing 121 or the second housing 122; in the width direction of the housing 12, the size of the first air passage 125 is related to the spacing between two adjacent convex beams. The ventilation cross-sectional area of the first air passage 125 is related to the size of the first air passage 125 in the width direction and the thickness direction of the housing 12.

[0145] Wherein, the second air passage 126 may have substantially the same size as the first air passage 125, or the second air passage 126 may have substantially the same ventilation cross-sectional area as the first air passage 125.

[0146] To prevent the aerosol from condensing to form condensate in the first air passage 125, the first air passage 125 may be set as a substantially straight air passage, or the first air passage 125 may be set as an air passage with a uniform size in the width direction of the housing 12, or the first air passage 125 may be set as an air passage with a uniform size in the thickness direction of the housing 12.

[0147] When the intake end 123 of the housing 12 has independent first intake ports 1231 and second intake ports 1232, two independent air holes may be provided on the aerosol generating device 2. The two air holes 24 are provided in one-to-one correspondence with the first intake ports 1231 and the second intake ports 1232. The outside air enters the inside of the aerosol generating device 2 through the two air holes 24 respectively, and then enters the first intake ports 1231 and the second intake ports 1232 independently respectively.

[0148] The above-mentioned aerosol generating article 1 and aerosol generating system include a housing 12 and a first aerosol forming substrate 111 and a second aerosol forming substrate 112 held inside the housing 12. The housing 12 has an intake end 123 and an outlet end 124, and the inside of the housing 12 has a first air passage 125 and a second air passage 126. The first air passage 125 and the second air passage 126 are respectively and independently connected to the intake end 123 and the outlet end 124. The volatile substances generated by the first aerosol forming substrate 111 and the second aerosol forming substrate 112 respectively enter the first air passage 125 and the second air passage 126. By using the first air passage 125 and the second air passage 126 to respectively conduct the volatile substances generated by the first aerosol forming substrate 111 and the second aerosol forming substrate 112, a large amount of condensate is prevented from accumulating in one air passage, thereby effectively avoiding the condensate from blocking the air passage and affecting the generation of volatile substances by the aerosol forming substrate 11 connected to the air passage. Therefore, it helps to ensure the taste and prevent the air passage from being blocked.

[0149] It should be noted that the description and drawings of this application provide preferred embodiments of this application, but are not limited to the embodiments described in this specification. Further, for those of ordinary skill in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this application.
