Description

Technical Field

[0001] This invention relates to an article for generating aerosols. More particularly, it relates to an article for generating inhalable aerosols upon heating. The article includes an aerosol generating matrix compartment for holding an aerosol generating matrix that generates inhalable aerosols upon heating. Background Technology

[0002] Articles in which an aerosol-generating matrix (such as a tobacco-containing matrix) is heated rather than burned are known in the art. Typically, in such heated smoking articles, an aerosol is generated by transferring heat from a heat source to a physically separated aerosol-generating matrix or material, which may be positioned, for example, in contact with, within, around, or downstream of a heat source. During use of the article, volatile compounds are released from the aerosol-generating matrix via heat transfer from the heat source and are entrained in the air drawn through the article. As the released compounds cool, they condense to form an aerosol.

[0003] Numerous prior art documents disclose aerosol generating apparatuses for consumer articles. Such apparatuses include, for example, electrically heated aerosol generating apparatuses, in which aerosols are generated by transferring heat from one or more electrically heated elements of the aerosol generating apparatus to an aerosol generating matrix of the heated article. For example, electrically heated aerosol generating apparatuses including internal heater blades adapted to be inserted into the aerosol generating matrix have been proposed. Combining the article with an external heating system is also known. For example, WO2020 / 115151A1 describes an arrangement in which one or more heating elements are arranged around the periphery of the article when it is received in the cavity of an aerosol generating apparatus. Alternatively, WO2015 / 176898A1 proposes an inductively heated article comprising an aerosol generating matrix and a sensor arranged within the aerosol generating matrix.

[0004] Air is typically drawn into the article through an air inlet. Air can enter the article before use. Air entering the article before use can reduce the quality of the aerosol-generating matrix contained within the article, which may reduce the quality of the aerosol delivered to the user during subsequent use of the article.

[0005] In particular, in humid environments, the aerosol-generating matrix may absorb moisture from the air entering the product before use. This can increase the temperature of the aerosol generated by the aerosol-generating matrix during the user's initial aspiration, which may be uncomfortable for the user. Therefore, the aerosol delivered to the user during the initial aspiration may differ from the aerosol delivered to the user during subsequent aspirations. Summary of the Invention

[0011] Advantageously, the article is provided with a means to prevent air from the outside of the article from coming into contact with the aerosol generating matrix stored in the aerosol generating matrix compartment until the user wants to use the article to generate aerosols. By sealing the aerosol generating matrix compartment away from the outside of the article before use, the amount of water absorbed by the aerosol generating matrix from humid air before the article is used is substantially reduced. Reducing the amount of water absorbed by the aerosol generating matrix before the article is used helps to avoid delivering unwanted warm aerosols to the user during the initial aspiration, which can contribute to a more consistent aerosol between the initial and subsequent aspirations.

[0012] Another advantage of reducing the amount of water absorbed by the aerosol generating matrix is ​​that the matrix stored in the aerosol generating matrix compartment can have a longer shelf life and can improve the quality of the aerosol delivered to the user.

When the outer and inner tubes are in the first configuration, the opening section of the inner tube can protrude from the outer tube. Advantageously, the protrusion of the inner tube from the outer tube provides the user with an easily actuated means of moving the outer and inner tubes from the first configuration to the second configuration.

[0054] Compared to the first configuration where the outer and inner tubes are in the first configuration, the inner tube can protrude from the outer tube to a greater extent when the outer and inner tubes are in the second configuration.

[0132] Advantageously, the inner tube sealing member is resilient, which helps prevent damage to the outer tube sealing member when the inner tube and / or outer tube move between the first and second configurations. Additionally, the resilient nature of the inner tube sealing member helps provide a more airtight seal when the inner and outer tube sealing members cooperate to prevent airflow through the airflow path.

[0133] At least a portion of the inner tube sealing member may include a soft material. The inner tube sealing member may include a soft material. The inner tube sealing member may include a coating of the soft material.

[0134] Advantageously, the inner tube sealing member being formed of a soft material helps prevent damage to the outer tube sealing member during movement of the inner tube and / or outer tube between the first and second configurations. Additionally, the soft material forming of the inner tube sealing member helps provide a more airtight seal when the inner and outer tube sealing members cooperate to prevent airflow through the airflow path.

[0135] The inner tube sealing component may include an inner tube sealing ring. The inner tube sealing ring may include a disc with a central opening.

[0136] The inner tube sealing component may include an inner tube sealing disc. The inner tube sealing disc may include one or more openings. The inner tube sealing disc includes a segmented disc.

The inner tube sealing member may be spaced apart from the inner surface of the outer tube, such that a radial clearance is provided between the inner tube sealing member and the inner surface of the outer tube.

[0139] The inner tube sealing member can extend radially outward from the outer surface of the inner tube to a certain height, said height exceeding the end face of the outer tube sealing member extending radially inward from the inner surface of the outer tube.

[0140] The inner tube sealing component may include an inner tube sealing ring. The inner tube sealing ring may be disposed on the outer surface of the inner tube. The inner tube sealing ring may be disposed on the outer peripheral surface of the inner tube. The inner tube sealing ring may extend around the outer peripheral surface of the inner tube. The inner tube sealing ring may extend around the entire circumference of the outer surface of the inner tube.

[0141] The inner and outer tubes are longitudinally movable relative to each other along the longitudinal axis of the article between the first and second structures. Movement of the inner or outer tubes relative to each other along the longitudinal axis of the article allows the inner and outer tubes to move between the first and second structures.

[0142] The inner and outer tubes can slide longitudinally relative to each other between the first and second structures along the longitudinal axis of the article. The sliding movement of the inner or outer tubes relative to each other along the longitudinal axis of the article allows the inner and outer tubes to move between the first and second structures.

[0143] The inner and outer tubes are rotatable relative to each other about the longitudinal axis of the article between the first and second structures. Rotational movement of the inner or outer tubes about the longitudinal axis of the article relative to each other allows the inner and outer tubes to move between the first and second structures.

[0144] The inner and outer tubes can be configured to be reversibly movable from a first configuration to a second configuration relative to each other. This provides a means for resealing the aerosol generation matrix compartment from the air outside the article after its initial use. The means of resealing the aerosol generation matrix compartment advantageously allows for the interruption of use of the article, and then subsequent resumption without adversely affecting the quality and consistency of the aerosol delivered to the user.

[0145] In the first configuration, the inner tube sealing member and the outer tube sealing member cooperate to substantially prevent air from flowing through the airflow passage.

[0146] In the first configuration, the inner tube sealing member and the outer tube sealing member can cooperate to substantially prevent air from flowing along the airflow path.

[0147] In the first configuration, the inner tube sealing member and the outer tube sealing member can cooperate to substantially prevent air from flowing through the first airflow passage.

[0148] In the first configuration, the inner tube sealing member and the outer tube sealing member can cooperate to substantially prevent air from flowing through the second airflow passage.

[0149] In the first configuration, the inner tube sealing member and the outer tube sealing member can be adjacent to each other to substantially prevent air from flowing through the airflow passage. In the first configuration, the inner tube sealing member and the outer tube sealing member can be adjacent to each other to substantially prevent air from flowing through the first airflow passage. In the first configuration, the inner tube sealing member and the outer tube sealing member can be adjacent to each other to substantially prevent air from flowing through the second airflow passage.

[0150] In the first configuration, the inner tube sealing member and the outer tube sealing member can be engaged with each other to form a seal that substantially prevents airflow along the airflow passage. In the first configuration, the inner tube sealing member and the outer tube sealing member can be engaged with each other to form a seal that substantially prevents airflow along the first airflow passage. In the first configuration, the inner tube sealing member and the outer tube sealing member can be engaged with each other to form a seal that substantially prevents airflow along the second airflow passage.

[0151] In the first configuration, the outer tube sealing member can be located between the inner tube sealing member and the aerosol generation matrix compartment.

[0152] In the first configuration, the outer tube sealing member can be located between the aerosol generation matrix compartment and the closed distal end of the body.

[0153] When the inner and outer tubes are in the first configuration, the inner tube can block the air inlet to substantially prevent airflow through the air inlet. This provides a simple manufacturing mechanism that substantially prevents airflow into the aerosol generation matrix compartment.

[0154] In the second configuration, the outer tube sealing member and the inner tube sealing member may provide at least one opening between the outer tube sealing member and the inner tube sealing member, the at least one opening allowing air to flow through the airflow passage.

[0155] In the second configuration, the outer tube sealing member and the inner tube sealing member may provide at least one opening between the outer tube sealing member and the inner tube sealing member, the at least one opening allowing air to flow through the first airflow passage.

[0156] In the second configuration, the outer tube sealing member and the inner tube sealing member may have at least one opening between them. At least one opening allows air to flow through the second airflow passage.

[0157] In the second configuration, the outer tube sealing member and the inner tube sealing member may be spaced apart to provide at least one opening between the outer tube sealing member and the inner tube sealing member. The at least one opening allows air to flow through an airflow passage.

[0158] In the second configuration, the distal end of the inner tube may be adjacent to the distal end of the outer tube. Advantageously, the sound generated by the distal end of the inner tube striking the distal end of the outer tube can serve as a prompt to the user that the inner and outer tubes are now in the second configuration.

[0159] When the inner tube and outer tube are in the second configuration, the inner tube may be located at least partially inside the outer tube.

[0160] In the second configuration, the inner tube sealing member can be located between the outer tube sealing member and the closed distal end of the body.

[0161] In the second configuration, the inner tube sealing member can be located between the air inlet and the closed distal end of the body.

[0162] In the second configuration, the inner tube sealing member can be located between the air inlet and the outer tube sealing member.

[0163] When the inner and outer tubes are in the second configuration, the inner tube can be spaced apart from the air inlet to allow airflow through the air inlet. This second position may be referred to as the open position. During use, the article can be in the second configuration.

[0164] When the inner and outer tubes are in the second configuration, the inner tube may be laterally spaced from the air inlet to allow airflow through the air inlet. For example, when the inner and outer tubes are in the second configuration, the inner tube may be at least partially located inside the outer tube, and the inner tube may be laterally spaced from the air inlet to allow airflow through the air inlet.

[0165] When the inner and outer tubes are in the second configuration, a space can be defined between the air inlet and the inner tube. The space defined between the air inlet and the inner tube can be an empty space.

[0166] When the inner and outer tubes are in the second configuration, the inner tube can be laterally spaced from the air inlet.

[0167] In the second configuration, the inner and outer tubes can be longitudinally displaced relative to the first configuration along the longitudinal axis of the article. In this example, in the second configuration, the outer tube sealing member and the inner tube sealing member can be spaced apart from each other to provide an opening between the outer tube sealing member and the inner tube sealing member. The opening can be a gap.

[0168] Providing an opening between the outer tube sealing member and the inner tube sealing member can open the first airflow passage to allow airflow along the first airflow passage.

[0169] In the second configuration, the inner and outer tubes can be rotatably displaced relative to the first configuration about the longitudinal axis of the article. In this example, in the second configuration, the outer tube sealing member and the inner tube sealing member can be adjacent to each other.

[0170] Between the first and second configurations, the inner tube sealing member and the outer tube sealing member can cooperate with each other to restrict airflow through the airflow path.

[0171] Restricting the airflow through the airflow path allows for adjustment of the suction resistance of the product.

[0172] The airflow through the flow passage can be restricted by adjusting the size of at least one opening between the outer and inner tube sealing components. Increasing the size of at least one opening allows for an increase in airflow through the flow passage. Decreasing the size of at least one opening reduces the airflow through the flow passage.

[0173] In one example, moving the outer and inner tubes from the first configuration to the second configuration increases the size of at least one opening, thereby allowing an increase in airflow through the airflow passage. In another example, moving the outer and inner tubes from the second configuration to the first configuration decreases the size of at least one opening, thereby allowing a decrease in airflow through the airflow passage.

[0174] In one example, as the outer and inner tubes move from a first configuration to a second configuration, the size of at least one opening increases, thereby allowing an increase in airflow through the airflow passage. In another example, as the outer and inner tubes move from a second configuration to a first configuration, the size of at least one opening decreases, thereby allowing a decrease in airflow through the airflow passage.

[0175] In one example, increasing the gap between the outer and inner tube sealing components allows for increased airflow through the airflow path. In another example, decreasing the gap between the outer and inner tube sealing components allows for decreased airflow through the airflow path.

[0176] The article may include a cap for sealing the open end of the body. The cap may be a removable cap. The cap may be removably attached to the open end of the body.

[0177] When the cap is attached to the opening of the body, it blocks the flow of air between the air outlet and the outside of the product through the opening of the body.

[0178] When the cap is removed from the opening of the body, air can flow through the opening of the body between the air outlet and the outside of the product.

[0179] The cap may include a protrusion.

[0180] The air passage may be defined at least partially by one or more grooves provided in the outer surface of the inner tube.

The ratio of the suction resistance of the outer tube to the total suction resistance of the product can be at least 0.6. The ratio of the suction resistance of the outer tube to the total suction resistance of the product can be at least 0.7.

The ratio of the suction resistance of the outer tube to the total suction resistance of the product can be at least 0.9. The ratio of the suction resistance of the outer tube to the total suction resistance of the product can be at least 0.95.

[0184] This ratio can be calculated based on the following: measuring the suction resistance of the article in the assembled state (in other words, the inner tube and outer tube are assembled) when the article is in the second configuration; measuring the suction resistance of the outer tube by drawing air from the mouth end through the air inlet when the article is in the second configuration; and then dividing this measured suction resistance of the outer tube by the measured suction resistance of the article in the assembled state.

[0274] The body 102 has an aerosol-generating matrix compartment 118 positioned toward its distal end 106. Figure 1 In this example, the aerosol generation matrix compartment 118 is defined by an annular space 116 at the closed distal end 106 of the body 102. The aerosol generation matrix compartment 118 is a cavity suitable for holding a certain amount of aerosol generation matrix, such as solid aerosol generation matrix. In this example, the aerosol generation matrix compartment 118 holds a certain amount of solid aerosol generation matrix 120.

[0275] The outer tube 108 has a generally cylindrical shape.

[0276] The inner tube 110 can be formed by one or more sections. Figure 1 In this example, the inner tube 110 has an end section 122, a distal section 124, and an intermediate section 126. The three sections 122, 124, and 126 of the inner tube 108 are formed separately and connected together to form a single piece. In this example, the end section 122 is located at the end 104 of the body 102, the distal section 124 is located at the distal end 106 of the body 102, and the intermediate section 126 extends between the end section 122 and the distal section 124.

[0277] The port section 122 of the inner tube 110 has an outer diameter that is substantially the same as the inner diameter of the outer tube 108. Therefore, at the port 104, the inner surface 112 of the outer tube 108 and the outer surface 114 of the inner tube 110 are adjacent to each other, thereby substantially preventing air from escaping between the inner tube 110 and the outer tube 108 at the port 104.

[0278] The distal section 124 of the inner tube 110 has an outer diameter much smaller than that of the port section 122. The distal section 124 of the inner tube 110 has an outer diameter much smaller than that of the outer tube 108. Therefore, at the distal end 106, the inner surface 112 of the outer tube 108 and the outer surface 114 of the inner tube 110 are spaced apart from each other.

[0279] The intermediate section 126 of the inner tube 110 has an outer diameter between the outer diameters of the port section 122 and the distal section 124. The outer diameter of the intermediate section 126 is smaller than the inner surface 112 of the outer tube 108.

[0280] The annular space 116 is provided in the space defined between the inner surface 112 of the outer tube 108 and the outer surfaces of the distal section 124 and the intermediate section 126.

[0281] The main body 102 has an air inlet 128. Figure 1 In this example, the air inlets are multiple air inlet holes provided in the wall of the outer tube 108. The air inlet holes are arranged in a row around the circumference of the outer tube 108.

[0282] The main body 102 has an air outlet 132. Figure 1 In this example, air outlet 132 is a plurality of air outlet holes provided in the wall of inner tube 110.

[0283] The airflow passage is defined to extend between the air inlet 128 and the open end 104 of the body 102. The airflow passage extends from the air inlet 128 through the aerosol generation matrix compartment 118, through the air outlet 132 and to the open end 104.

[0284] exist Figure 1 In the example, the airflow passage includes a first airflow passage 130 and a second airflow passage 134.

[0285] A first airflow passage 130 extends between an air inlet 128 and an aerosol generation matrix compartment 118. The first airflow passage 130 passes through an annular space 116 defined between the inner surface 112 of the outer tube 108 and the outer surface 114 of the inner tube 110. In this way, the air inlet 128 provides fluid communication between the aerosol generation matrix compartment 118 and the exterior of the article 100.

[0286] The second airflow passage 134 extends between the aerosol generation matrix compartment 118 and the open end 104 of the body 102. The second airflow passage 134 passes through the internal space defined by the inner tube 110, through the air outlet 132, and reaches the open end 104. In this way, the air outlet 132 provides fluid communication between the aerosol generation matrix compartment 118 and the open end 104 of the body 102.

[0287] Figure 2 A schematic diagram of a first example of an article 200 for generating an inhalable aerosol upon heating is shown.

[0288] Article 200 has a body 202. The body 202 has an opening 204 and a distal end 206. In this example, the opening 204 of the body 202 is open, and the distal end 206 of the body 202 is closed. In other words, air can flow out of the body 202 at the opening 204, but air cannot easily flow out of the distal end 206 of the body 202.

[0289] The body 202 has an outer tube 208 and an inner tube 210. The outer tube 208 has an inner surface 212, and the inner tube 210 has an outer surface 214. The inner tube 210 is disposed inside the outer tube 208. A space 216 is defined between the inner surface 212 of the outer tube 208 and the outer surface 214 of the inner tube 210. Figure 1 In the example, the space is a toroidal space 216.

[0290] The body 202 has an aerosol-generating matrix compartment 218 positioned toward its distal end 206. Figure 2 In this example, the aerosol generation matrix compartment 218 is defined by an annular space 216 at the closed distal end 206 of the body 202. The aerosol generation matrix compartment 218 is a cavity suitable for holding a certain amount of aerosol generation matrix, such as solid aerosol generation matrix. In this example, the aerosol generation matrix compartment 218 holds a certain amount of solid aerosol generation matrix 220.

[0291] The outer tube 208 has a generally cylindrical shape.

[0292] The inner tube 210 can be formed by one or more sections. Figure 2 In this example, the inner tube 210 has an end section 222, a distal section 224, and an intermediate section 226. The three sections 222, 224, and 226 of the inner tube 208 are formed separately and connected together to form a single piece. In this example, the end section 222 is located at the end 204 of the body 202, the distal section 224 is located at the distal end 206 of the body 202, and the intermediate section 226 extends between the end section 222 and the distal section 224.

[0293] The port section 222 of the inner tube 210 has an outer diameter that is substantially the same as the inner diameter of the outer tube 208. Therefore, at the port 204, the inner surface 212 of the outer tube 208 and the outer surface 214 of the inner tube 210 are adjacent to each other, thereby substantially preventing air from escaping between the inner tube 210 and the outer tube 208 at the port 204.

[0294] The distal section 224 of the inner tube 210 has an outer diameter much smaller than that of the port section 222. The distal section 224 of the inner tube 210 has an outer diameter much smaller than that of the outer tube 208. Therefore, at the distal end 206, the inner surface 212 of the outer tube 208 and the outer surface 214 of the inner tube 210 are spaced apart from each other.

[0295] The intermediate section 226 of the inner tube 210 has an outer diameter between the outer diameters of the port section 222 and the distal section 224. The outer diameter of the intermediate section 226 is smaller than the inner surface 212 of the outer tube 208.

[0296] The annular space 216 is provided in the space defined between the inner surface 212 of the outer tube 208 and the outer surfaces of the distal section 224 and the intermediate section 226.

[0297] The main body 202 has an air inlet 228. In Figure 2 In this example, the air inlets are multiple air inlet holes located in the wall of the outer tube 208. The air inlet holes are arranged in a row around the circumference of the outer tube 208.

[0298] The main body 202 has an air outlet 232. In Figure 2 In this example, air outlet 232 is a plurality of air outlet holes provided in the wall of inner tube 210.

[0299] The airflow passage is defined to extend between the air inlet 228 and the open end 204 of the body 202. The airflow passage extends from the air inlet 228 through the aerosol generation matrix compartment 218, through the air outlet 232 and to the open end 204.

[0300] exist Figure 2 In the example, the airflow passage includes a first airflow passage 230 and a second airflow passage 234.

[0301] A first airflow passage 230 extends between an air inlet 228 and an aerosol generation matrix chamber 218. The first airflow passage 230 passes through an annular space 216 defined between the inner surface 212 of the outer tube 208 and the outer surface 214 of the inner tube 210. In this way, the air inlet 228 provides fluid communication between the aerosol generation matrix chamber 218 and the exterior of the article 200.

[0302] The second airflow passage 234 extends between the aerosol generation matrix compartment 218 and the open end 204 of the body 202. The second airflow passage 234 passes through the internal space defined by the inner tube 210, through the air outlet 232, and reaches the open end 204. In this way, the air outlet 232 provides fluid communication between the aerosol generation matrix compartment 218 and the open end 204 of the body 202.

[0303] The outer tube 208 includes an outer tube sealing member 236. In Figure 2 In this example, the outer tube sealing member 236 extends radially inward from the inner surface 212 of the outer tube 208. In other words, the outer tube sealing member 236 protrudes toward the inner tube 210. Figure 2 In this example, the outer tube sealing member 236 is an outer tube sealing ring integrally formed with the outer tube 208. The outer tube sealing ring extends circumferentially around the inner surface 212 of the outer tube 208.

[0304] The inner tube 210 includes an inner tube sealing member 238. Figure 2 In this example, the inner tube sealing member 238 extends radially outward from the outer surface 214 of the inner tube 210. In other words, the inner tube sealing member 238 protrudes toward the outer tube 208. Figure 2 In this example, the inner tube sealing member 238 is an inner tube sealing ring integrally formed with the inner tube 210. The inner sealing ring extends circumferentially around the outer surface 214 of the inner tube 210.

[0305] The outer tube 208 and the inner tube 210 are movable relative to each other between the first and second structures. Figure 2 In this example, the outer tube 208 and the inner tube 210 are longitudinally movable relative to each other. In other words, the outer tube 208 and / or the inner tube 210 can be displaced relative to each other along the longitudinal axis of the article 200.

[0306] Figure 2 An article 200 is shown having an outer tube 208 and an inner tube 210 in a first configuration. In this first configuration, the outer tube sealing member 236 and the inner tube sealing member 238 cooperate with each other to substantially prevent airflow through the airflow passage. Figure 2In the example, in the first configuration, the outer tube sealing member 236 and the inner tube sealing member 238 are adjacent to each other to create a substantially airtight seal. The seal created by the adjacent outer tube sealing member 236 and the inner tube sealing member 238 substantially prevents air from flowing between the air inlet 228 and the aerosol generating matrix compartment 218.

[0307] exist Figure 2 In this example, when the outer tube 208 and the inner tube 210 are in the first configuration, the inner tube 210 protrudes from the outer tube 208. The protrusion of the inner tube 210 from the outer tube 208 provides the user with an easily activating means to move the outer tube 208 and the inner tube 210 from the first configuration to the second configuration.

[0308] Figure 3 A schematic diagram of article 200 is shown with the outer tube 208 and inner tube 210 in the second configuration. Article 200 has the same characteristics as described above. Figure 2 The same features are described.

[0309] In order to move the outer tube 208 and the inner tube 210 between the first configuration and the second configuration, the user can, for example, slide the inner tube 210 longitudinally relative to the outer tube 208.

[0310] As the outer tube 208 and inner tube 210 move from the first configuration to the second configuration, the inner tube 210 is pushed past the outer tube 208 and toward the aerosol generation matrix compartment 218. Figure 2 As shown, when the outer tube 208 and inner tube 210 are in the first configuration, the outer tube sealing member 236 is closer to the aerosol generation matrix compartment 218 than the inner tube sealing member 238. Figure 3 As shown, when the outer tube 208 and inner tube 210 are in the second configuration, the inner tube sealing member 238 is closer to the aerosol generation matrix compartment 218 than the outer tube sealing member 236. To facilitate the inner tube sealing member 238 being pushed through the outer tube sealing member 236, in Figure 2 and Figure 3 In this example, both the outer tube sealing member 236 and the inner tube sealing member 238 are formed of a resilient material such as rubber. Forming the outer tube sealing member 236 and the inner tube sealing member 238 facilitates their flexing as the outer tube 208 and the inner tube 210 move from the first configuration to the second configuration.

[0311] exist Figure 3In this example, in the second configuration, the outer tube sealing member 236 and the inner tube sealing member 238 are longitudinally spaced apart. When the outer tube sealing member 236 and the inner tube sealing member 238 are spaced apart, a gap is created between the outer tube sealing member 236 and the inner tube sealing member 238. The gap between the outer tube sealing member 236 and the inner tube sealing member 238 allows air to flow through the first airflow passage 230 between the air inlet 228 and the aerosol generation matrix compartment 218.

[0312] When the outer tube 208 and inner tube 210 are in the configuration between the first and second configurations, the opening between the outer tube sealing member 236 and the inner tube sealing member 238 restricts the airflow through the first airflow passage 230, thereby reducing the airflow between the air inlet 228 and the aerosol generation matrix chamber 218. When the outer tube 208 and inner tube 210 are in the configuration between the first and second configurations, the opening between the outer tube sealing member 236 and the inner tube sealing member 238 also restricts the airflow through the second airflow passage 234, thereby reducing the airflow between the aerosol generation matrix chamber 218 and the open end 204 of the body 202.

[0313] The outer tube 208 and inner tube 210 are slidably movable relative to each other along the longitudinal axis of the article 200 to adjust the size of the opening between the outer tube sealing member 236 and the inner tube sealing member 238. Adjusting the size of the opening between the outer tube sealing member 236 and the inner tube sealing member 238 allows for adjustment of the restriction on airflow through the first airflow passage 230. Figure 3 In one example, adjusting the size of the opening between the outer tube sealing member 236 and the inner tube sealing member 238 also allows for adjustment of the restriction on airflow through the second airflow passage 234.

[0314] Therefore, by moving the outer tube 208 and the inner tube 210 relative to each other along the longitudinal axis of the product 200, the suction resistance of the product 200 can be adjusted.

[0315] Figure 4 A schematic diagram of a second example of an article 300 for generating an inhalable aerosol upon heating is shown.

[0316] Article 300 has a body 302. The body 302 has an opening 304 and a distal end 306. In this example, the opening 304 of the body 302 is open, and the distal end 306 of the body 302 is closed. In other words, air can flow out of the body 302 at the opening 304, but air cannot easily flow out of the distal end 306 of the body 302.

[0317] The body 302 has an outer tube 308 and an inner tube 310. The outer tube 308 has an inner surface 312, and the inner tube 310 has an outer surface 314. The inner tube 310 is disposed inside the outer tube 308. A space 316 is defined between the inner surface 312 of the outer tube 308 and the outer surface 314 of the inner tube 310. Figure 4 In the example, the space is a toroidal space 116.

[0318] The body 302 has an aerosol generation matrix compartment 318 positioned toward the distal end 306 of the body 302. Figure 4 In this example, the aerosol generation matrix compartment 318 is defined by an annular space 316 facing the closed distal end 306 of the body 302. The aerosol generation matrix compartment 318 is a cavity suitable for holding a certain amount of aerosol generation matrix, such as solid aerosol generation matrix. In this example, the aerosol generation matrix compartment 318 holds a certain amount of solid aerosol generation matrix 320.

[0319] The outer tube 308 has a generally cylindrical shape.

[0320] The inner tube 310 can be formed by one or more sections. Figure 4 In this example, the inner tube 310 has an end section 322, a distal section 324, and an intermediate section 326. The three sections 322, 324, and 326 of the inner tube 308 are formed separately and connected together to form a single piece. In this example, the end section 322 is positioned toward the end 304 of the body 302, the distal section 324 is positioned toward the distal end 306 of the body 302, and the intermediate section 326 extends between the end section 322 and the distal section 324.

[0321] The port section 322 of the inner tube 310 has an outer diameter that is substantially the same as the inner diameter of the outer tube 308. Therefore, at the port 304, the inner surface 312 of the outer tube 308 and the outer surface 314 of the inner tube 310 are adjacent to each other, thereby substantially preventing air from escaping between the inner tube 310 and the outer tube 308 at the port 304.

[0322] The distal section 324 of the inner tube 310 has an outer diameter much smaller than that of the port section 322. The distal section 324 of the inner tube 310 has an outer diameter much smaller than that of the outer tube 308. Therefore, at the distal end 306, the inner surface 312 of the outer tube 308 and the outer surface 314 of the inner tube 310 are spaced apart from each other.

[0323] The intermediate section 326 of the inner tube 310 has an outer diameter between the outer diameters of the port section 322 and the distal section 324. The outer diameter of the intermediate section 326 is smaller than the inner surface 312 of the outer tube 308.

[0324] The annular space 316 is provided in the space between the inner surface 312 of the outer tube 308 and the outer surfaces of the distal section 324 and the intermediate section 326.

[0325] Body 302 has an air inlet 328. In Figure 4 In this example, the air inlets are multiple air inlet holes located in the wall of the outer tube 308. The air inlet holes are arranged in a row around the circumference of the outer tube 308.

[0326] Body 302 has an air outlet 332. Figure 4 In this example, air outlet 332 is a plurality of air outlet holes provided in the wall of the distal section 324 of the inner tube 310.

[0327] The airflow passage is defined to extend between the air inlet 328 and the open end 304 of the body 302. The airflow passage extends from the air inlet 328 through the aerosol generation matrix compartment 318, through the air outlet 332 and to the open end 304.

[0328] exist Figure 4 In the example, the airflow passage includes a first airflow passage 330 and a second airflow passage 334.

[0329] A first airflow passage 330 extends between an air inlet 328 and an aerosol generation matrix chamber 318. The first airflow passage 330 passes through an annular space 316 defined between the inner surface 312 of the outer tube 308 and the outer surface 314 of the inner tube 310. In this way, the air inlet 328 provides fluid communication between the aerosol generation matrix chamber 318 and the exterior of the article 300.

[0330] The second airflow passage 334 extends between the aerosol generation matrix compartment 318 and the open end 304 of the body 302. The second airflow passage 334 passes through the internal space defined by the inner tube 310, through the air outlet 332, and reaches the open end 304. In this way, the air outlet 332 provides fluid communication between the aerosol generation matrix compartment 318 and the open end 304 of the body 302.

[0331] The outer tube 308 includes an outer tube sealing member 336. The outer tube sealing member 336 extends radially inward from the inner surface 312 of the outer tube 308. In other words, the outer tube sealing member 336 protrudes toward the inner tube 310. Figure 4 In this example, the outer tube sealing member 336 is an outer tube sealing ring integrally formed with the outer tube 308. The outer tube sealing ring extends circumferentially around the inner surface 312 of the outer tube 308.

[0332] The inner tube 310 includes an inner tube sealing member 338. The inner tube sealing member 338 extends radially outward from the outer surface 314 of the inner tube 310. In other words, the inner tube sealing member 338 protrudes toward the outer tube 308. Figure 4 In this example, the inner tube sealing member 338 is an inner tube sealing ring integrally formed with the inner tube 310. The inner sealing ring extends circumferentially around the outer surface 314 of the inner tube 310.

[0333] The outer tube 308 and the inner tube 310 are movable relative to each other between the first and second structures. Figure 4 In this example, the outer tube 308 and the inner tube 310 are longitudinally movable relative to each other. In other words, the outer tube 308 and / or the inner tube 310 can be displaced relative to each other along the longitudinal axis of the article 300.

[0334] Figure 4 An article 300 is shown having an outer tube 308 and an inner tube 310 in a first configuration. In this first configuration, the outer tube sealing member 336 and the inner tube sealing member 338 cooperate with each other to substantially prevent air from flowing through the first airflow passage. Figure 4 In the example, in the first configuration, the outer tube sealing member 336 and the inner tube sealing member 338 are adjacent to each other to create a substantially airtight seal. The seal created by the adjacent outer tube sealing member 336 and the inner tube sealing member 338 substantially prevents air from flowing between the air inlet 328 and the aerosol generating matrix compartment 318.

[0335] In addition, in the first configuration, the inner tube 310 blocks the air inlet 328 to substantially prevent airflow through the air inlet 328.

[0336] exist Figure 4 In this example, when the outer tube 308 and the inner tube 310 are in the first configuration, the inner tube 310 protrudes from the outer tube 308. The protrusion of the inner tube 310 from the outer tube 308 provides the user with an easily activating means to move the outer tube 308 and the inner tube 310 from the first configuration to the second configuration.

[0337] exist Figure 4 In this example, the air outlet 332 is located between the inner tube sealing member 338 and the distal end 306 of the body 302. Advantageously, positioning the air outlet 332 between the inner tube sealing member 338 and the distal end 306 of the body 302 can increase the circulation of air through the airflow path when the outer tube 308 and the inner tube 310 are in the second configuration.

[0338] Figure 5 A schematic diagram of article 300 is shown with the outer tube 308 and inner tube 310 in the second configuration. Article 300 has the same characteristics as described above. Figure 4 The same features are described.

[0339] In order to move the outer tube 308 and the inner tube 310 between the first configuration and the second configuration, the user can, for example, slide the inner tube 310 longitudinally relative to the outer tube 308.

[0340] As the outer tube 308 and inner tube 310 move from the first configuration to the second configuration, the inner tube 310 is pushed past the outer tube 308 and toward the aerosol generation matrix compartment 318. Figure 5 As shown, when the outer tube 308 and inner tube 310 are in the first configuration, the outer tube sealing member 336 is closer to the aerosol generation matrix compartment 318 than the inner tube sealing member 338. Figure 5 As shown, when the outer tube 308 and inner tube 310 are in the second configuration, the inner tube sealing member 338 is closer to the aerosol generation matrix compartment 318 than the outer tube sealing member 336. To facilitate the inner tube sealing member 338 being pushed through the outer tube sealing member 336, in Figure 4 and Figure 5 In this example, both the outer tube sealing member 336 and the inner tube sealing member 338 are formed of a resilient material such as rubber. Forming the outer tube sealing member 336 and the inner tube sealing member 338 facilitates their flexing as the outer tube 308 and the inner tube 310 move from the first configuration to the second configuration.

[0341] exist Figure 5 In this example, in the second configuration, the outer tube sealing member 336 and the inner tube sealing member 338 are longitudinally spaced apart. When the outer tube sealing member 336 and the inner tube sealing member 338 are spaced apart, a gap is created between the outer tube sealing member 336 and the inner tube sealing member 338. The gap between the outer tube sealing member 336 and the inner tube sealing member 338 allows air to flow through the first airflow passage 330 between the air inlet 328 and the aerosol generation matrix compartment 318.

[0342] When the outer tube 308 and inner tube 310 are in the configuration between the first and second configurations, the opening between the outer tube sealing member 336 and the inner tube sealing member 338 restricts the airflow through the first airflow passage 330, thereby reducing the airflow between the air inlet 328 and the aerosol generation matrix chamber 318. When the outer tube 308 and inner tube 310 are in the configuration between the first and second configurations, the opening between the outer tube sealing member 336 and the inner tube sealing member 338 also restricts the airflow through the second airflow passage 334, thereby reducing the airflow between the aerosol generation matrix chamber 318 and the open end 304 of the body 302.

[0343] The outer tube 308 and the inner tube 310 are slidably movable relative to each other along the longitudinal axis of the article 300 to adjust the size of the opening between the outer tube sealing member 336 and the inner tube sealing member 338. Adjusting the size of the opening between the outer tube sealing member 336 and the inner tube sealing member 338 allows for adjustment of the restriction on airflow through the first airflow passage 330. Figure 5 In one example, adjusting the size of the opening between the outer tube sealing member 336 and the inner tube sealing member 338 also allows for adjustment of the restriction on airflow through the second airflow passage 334.

[0344] Therefore, by moving the outer tube 308 and the inner tube 310 relative to each other along the longitudinal axis of the product 300, the suction resistance of the product 300 can be adjusted.

[0345] Figure 6 A schematic diagram of a third example of an article 400 for generating an inhalable aerosol upon heating is shown.

[0346] Article 400 has a body 402. The body 402 has an opening 404 and a distal end 406. In this example, the opening 404 of the body 402 is open, and the distal end 406 of the body 402 is closed. In other words, air can flow out of the body 402 at the opening 404, but air cannot easily flow out of the distal end 406 of the body 402.

[0347] The body 402 has an outer tube 408 and an inner tube 410. The outer tube 408 has an inner surface 412, and the inner tube 410 has an outer surface 414. The inner tube 410 is disposed inside the outer tube 408. A space 416 is defined between the inner surface 412 of the outer tube 408 and the outer surface 414 of the inner tube 410. Figure 6 In this example, the space is a toroidal space 416.

[0348] The body 402 has an aerosol-generating matrix compartment 418 positioned toward its distal end 406. Figure 6 In this example, the aerosol generation matrix compartment 418 is defined by an annular space 416 facing the closed distal end 406 of the body 402. The aerosol generation matrix compartment 418 is a cavity suitable for holding a certain amount of aerosol generation matrix, such as solid aerosol generation matrix. In this example, the aerosol generation matrix compartment 418 holds a certain amount of solid aerosol generation matrix 420.

[0349] The outer tube 408 has a generally cylindrical shape.

[0350] The inner tube 410 can be formed by one or more sections. Figure 6In this example, the inner tube 410 has an end section 422, a distal section 424, and an intermediate section 426. The three sections 422, 424, and 426 of the inner tube 408 are formed separately and connected together to form a single piece. In this example, the end section 422 is positioned toward the end 404 of the body 402, the distal section 424 is positioned toward the distal end 406 of the body 402, and the intermediate section 426 extends between the end section 422 and the distal section 424.

[0351] The port section 422 of the inner tube 410 has an outer diameter that is substantially the same as the inner diameter of the outer tube 408. Therefore, at the port 404, the inner surface 412 of the outer tube 408 and the outer surface 414 of the inner tube 410 are adjacent to each other, thereby substantially preventing air from escaping between the inner tube 410 and the outer tube 408 at the port 404.

[0352] The distal section 424 of the inner tube 410 has an outer diameter much smaller than that of the port section 422. The distal section 424 of the inner tube 410 has an outer diameter much smaller than that of the outer tube 408. Therefore, at the distal end 406, the inner surface 412 of the outer tube 408 and the outer surface 414 of the inner tube 410 are spaced apart from each other.

[0353] The intermediate section 426 of the inner tube 410 has an outer diameter between the outer diameters of the port section 422 and the distal section 424. The outer diameter of the intermediate section 426 is smaller than the inner surface 412 of the outer tube 408.

[0354] The annular space 416 is provided in the space defined between the inner surface 412 of the outer tube 408 and the outer surfaces of the distal section 424 and the intermediate section 426.

[0355] Body 402 has an air inlet 428. Figure 6 In this example, the air inlets are multiple air inlet holes located in the wall of the outer tube 408. The air inlet holes are arranged in a row around the circumference of the outer tube 408.

[0356] The main body 402 has an air outlet 432. In Figure 6 In this example, air outlet 432 is an air outlet hole configured to pass through the end wall of inner tube 410 and be positioned toward the distal end 406 of body 402.

[0357] The airflow passage is defined to extend between the air inlet 428 and the open end 404 of the body 402. The airflow passage extends from the air inlet 428 through the aerosol generation matrix compartment 418, through the air outlet 432 and to the open end 404.

[0358] exist Figure 6 In the example, the airflow passage includes a first airflow passage 430 and a second airflow passage 434.

[0359] A first airflow passage 430 extends between an air inlet 428 and an aerosol generation matrix chamber 418. The first airflow passage 430 passes through an annular space 416 defined between the inner surface 412 of the outer tube 408 and the outer surface 414 of the inner tube 410. In this way, the air inlet 428 provides fluid communication between the aerosol generation matrix chamber 418 and the exterior of the article 400.

[0360] A second airflow passage 434 extends between the aerosol generation matrix compartment 418 and the open end 404 of the article 400. The second airflow passage 434 passes through the internal space defined by the inner tube 410, through the air outlet 432, and reaches the open end 404. In this way, the air outlet 432 provides fluid communication between the aerosol generation matrix compartment 418 and the open end 404 of the body 402.

[0361] Advantageously, arranging the air outlet 432 through the end wall of the inner tube 410 can increase air circulation through the airflow passage when the outer tube 408 and the inner tube 410 are in the second configuration.

[0362] The outer tube 408 includes an outer tube sealing member 436. The outer tube sealing member 436 extends radially inward from the inner surface 412 of the outer tube 408. In other words, the outer tube sealing member 436 protrudes toward the inner tube 410. Figure 6 In this example, the outer tube sealing member 436 is an outer tube sealing ring integrally formed with the outer tube 408. The outer tube sealing ring extends circumferentially around the inner surface 412 of the outer tube 408.

[0363] The inner tube 410 includes an inner tube sealing member 438. The inner tube sealing member 438 extends radially outward from the outer surface 414 of the inner tube 410. In other words, the inner tube sealing member 438 protrudes toward the outer tube 408. Figure 6 In this example, the inner tube sealing member 438 is an inner tube sealing ring integrally formed with the inner tube 410. The inner sealing ring extends circumferentially around the outer surface 414 of the inner tube 410.

[0364] The outer tube 408 and the inner tube 410 are movable relative to each other between the first and second structures. Figure 6 In this example, the outer tube 408 and the inner tube 410 are longitudinally movable relative to each other. In other words, the outer tube 408 and / or the inner tube 410 can be displaced relative to each other along the longitudinal axis of the article 400.

[0365] Figure 6 An article 400 is shown having an outer tube 408 and an inner tube 410 in a first configuration. In this first configuration, the outer tube sealing member 436 and the inner tube sealing member 438 cooperate with each other to substantially prevent air from flowing through the first airflow passage. Figure 6In the example, in the first configuration, the outer tube sealing member 436 and the inner tube sealing member 438 are adjacent to each other to create a substantially airtight seal. The seal created by the adjacent outer tube sealing member 436 and the inner tube sealing member 438 substantially prevents air from flowing between the air inlet 428 and the aerosol generating matrix compartment 418.

[0366] exist Figure 6 In this example, when the outer tube 408 and the inner tube 410 are in the first configuration, the inner tube 410 protrudes from the outer tube 408. The protrusion of the inner tube 410 from the outer tube 408 provides the user with an easily activating means to move the outer tube 408 and the inner tube 410 from the first configuration to the second configuration.

[0367] Figure 7 A schematic diagram of article 400 is shown with the outer tube 408 and inner tube 410 in the second configuration. Article 400 has the same characteristics as described above. Figure 6 The same features are described.

[0368] In order to move the outer tube 408 and the inner tube 410 between the first configuration and the second configuration, the user can, for example, slide the inner tube 410 longitudinally relative to the outer tube 408.

[0369] As the outer tube 408 and inner tube 410 move from the first configuration to the second configuration, the inner tube 410 is pushed past the outer tube 408 and toward the aerosol generation matrix compartment 418. Figure 6 As shown, when the outer tube 408 and inner tube 410 are in the first configuration, the outer tube sealing member 436 is closer to the aerosol generation matrix compartment 418 than the inner tube sealing member 438. Figure 7 As shown, when the outer tube 408 and inner tube 410 are in the second configuration, the inner tube sealing member 438 is closer to the aerosol generation matrix compartment 418 than the outer tube sealing member 436. To facilitate the inner tube sealing member 438 being pushed through the outer tube sealing member 436, in Figure 6 and Figure 7 In this example, both the outer tube sealing member 436 and the inner tube sealing member 438 are formed of a resilient material such as rubber. Forming the outer tube sealing member 436 and the inner tube sealing member 438 facilitates their flexing as the outer tube 408 and the inner tube 410 move from the first configuration to the second configuration.

[0370] exist Figure 7In this example, in the second configuration, the outer tube sealing member 436 and the inner tube sealing member 438 are longitudinally spaced apart. When the outer tube sealing member 436 and the inner tube sealing member 438 are spaced apart, a gap is created between the outer tube sealing member 436 and the inner tube sealing member 438. The gap between the outer tube sealing member 436 and the inner tube sealing member 438 allows air to flow through the first airflow passage 430 between the air inlet 428 and the aerosol generation matrix compartment 418.

[0371] When the outer tube 408 and inner tube 410 are in the configuration between the first and second configurations, the opening between the outer tube sealing member 436 and the inner tube sealing member 438 restricts the airflow through the first airflow passage 430, thereby reducing the airflow between the air inlet 428 and the aerosol generation matrix chamber 418. When the outer tube 408 and inner tube 410 are in the configuration between the first and second configurations, the opening between the outer tube sealing member 436 and the inner tube sealing member 438 also restricts the airflow through the second airflow passage 434, thereby reducing the airflow between the aerosol generation matrix chamber 418 and the open end 404 of the body 402.

[0372] The outer tube 408 and the inner tube 410 are slidably movable relative to each other along the longitudinal axis of the article 400 to adjust the size of the opening between the outer tube sealing member 436 and the inner tube sealing member 438. Adjusting the size of the opening between the outer tube sealing member 436 and the inner tube sealing member 438 allows for adjustment of the restriction on airflow through the first airflow passage 430. Figure 7 In one example, adjusting the size of the opening between the outer tube sealing member 436 and the inner tube sealing member 438 also allows for adjustment of the restriction on airflow through the second airflow passage 434.

[0373] Therefore, by moving the outer tube 408 and the inner tube 410 relative to each other along the longitudinal axis of the product 400, the suction resistance of the product 400 can be adjusted.

[0374] Figure 8 A schematic diagram of an aerosol generation system 500 is shown. The aerosol generation system 500 includes an article 200 and an aerosol generation device 502.

[0375] The aerosol generating apparatus 502 includes a housing 504 extending between a first end 506 and a second end 508. The housing 504 has a peripheral wall 510. The peripheral wall 510 defines a heating chamber for receiving an article 200. The heating chamber is defined by a closed first end and an open second end. The second end of the heating chamber is located at the second end of the aerosol generating apparatus 502. In use, the article 200 is received through the second end of the heating chamber and may be adjacent to the first end of the heating chamber. Figure 8 In the example shown, article 200 is received in a heating chamber.

[0376] When article 200 is received in the heating chamber, air inlet 228 remains outside the heating chamber. The presence of air inlet 228 outside the heating chamber allows air to be easily drawn into article 200.

[0377] The aerosol generating apparatus 502 also includes a heater 512 and a power supply 514 for supplying power to the heater. The aerosol generating apparatus 502 also includes a controller 516 for controlling the power supply from the power supply 514 to the heater 512. The controller 516 is configured to controllably heat the aerosol generating matrix compartment 218 of the article 200 during use when the article 200 is received in the heating chamber.

[0378] exist Figure 8 In the example shown, heater 512 is arranged to heat article 200 from the outside.

[0379] In use, the aerosol generating matrix 220 is placed in the aerosol generating matrix compartment 218. Then, the inner tube 210 is slid inside the outer tube 208 until the inner tube sealing member 238 contacts the outer tube sealing member 236, thereby placing the outer tube 208 and the inner tube 210 in a first configuration. In this first configuration, the seal between the inner tube sealing member 238 and the outer tube sealing member 236 prevents air from flowing along the airflow path. Specifically, in Figure 8 In one example, in the first configuration, the seal between the inner tube sealing member 238 and the outer tube sealing member 236 prevents air from flowing along the first airflow passage 230 between the air inlet 228 and the aerosol generating matrix compartment 218.

[0380] In order to generate an aerosol, the inner tube 210 is first moved toward the distal end 206 within the outer tube 208, and the outer tube 208 and the inner tube 210 are moved into the second configuration.

[0381] Sliding the inner tube 210 relative to the outer tube 208 pushes the inner tube sealing member 238 toward the distal end 206 and past the outer tube sealing member 236. To allow the inner tube sealing member 238 to be pushed past the outer tube sealing member 236, at least one of the inner tube sealing member 238 and the outer tube sealing member 236 is flexible. As the inner tube sealing member 238 moves toward the distal end 206 and away from the outer tube sealing member 236, the airflow passage is open to allow air to flow between the aerosol generation matrix compartment 218 and the open end of the body 202. Specifically, in Figure 8In this example, when the inner tube sealing member 238 moves toward the distal end 206 and away from the outer tube sealing member 236, the second airflow passage 234 is open to allow air to flow between the aerosol generating matrix chamber 218 and the open end 204 of the body 202. In this example, when the outer tube 208 and the inner tube 210 are in the second configuration, the distal end of the inner tube 210 is in contact with the distal end of the outer tube 208. In the second configuration, aerosols generated by evaporating the aerosol generating matrix 220 can be drawn from the aerosol generating matrix chamber 218 and extracted from the article 200 through the open end 204 of the body 202.

[0382] After the outer tube 208 and inner tube 210 are moved to the second configuration, the article 200 is inserted into the heating chamber of the aerosol generating apparatus 502. The aerosol generating apparatus 502 is then started. Upon starting the aerosol generating apparatus 502, the controller 516 raises the heater temperature and heats the article 200 from the outside. Heating the article 200 at the aerosol generating matrix compartment 218 causes the volatile components of the aerosol generating matrix 220 to evaporate. The evaporated volatile components can be drawn along the second gas flow path and extracted from the article through the open end 204 of the body 202.

[0383] Figure 9 A schematic diagram of a fourth example of an article 600 for generating an inhalable aerosol upon heating is shown.

[0384] Article 600 has a body 602. The body 602 has an opening 604 and a distal end 606. In this example, the opening 604 of the body 602 is open, and the distal end 606 of the body 602 is closed. In other words, air can flow out of the body 602 at the opening 604, but air cannot easily flow out of the distal end 606 of the body 602.

[0385] The body 602 has an outer tube 608 and an inner tube 610. The outer tube 608 has an inner surface 612, and the inner tube 610 has an outer surface 614. The inner tube 610 is disposed inside the outer tube 608. A space 616 is defined between the inner surface 612 of the outer tube 608 and the outer surface 614 of the inner tube 610. Figure 9 In this example, the space is a toroidal space 616.

[0386] The body 602 has an aerosol-generating matrix compartment 618 positioned toward its distal end 606. Figure 9 In this example, the aerosol generation matrix compartment 618 is defined by an annular space 616 at the closed distal end 606 of the body 602. The aerosol generation matrix compartment 618 is a cavity suitable for holding a certain amount of aerosol generation matrix, such as a solid aerosol generation matrix. In this example, the aerosol generation matrix compartment 618 holds a certain amount of solid aerosol generation matrix 620.

[0387] The outer tube 608 has a generally cylindrical shape.

[0388] The inner tube 610 can be formed by one or more sections. Figure 9 In this example, the inner tube 610 has an end section 622, a distal section 624, and an intermediate section 626. The three sections 622, 624, and 626 of the inner tube 608 are formed separately and connected together to form a single piece. In this example, the end section 622 is located at the end 604 of the body 602, the distal section 624 is located at the distal end 606 of the body 602, and the intermediate section 626 extends between the end section 622 and the distal section 624.

[0389] The port section 622 of the inner tube 610 has an outer diameter that is substantially the same as the inner diameter of the outer tube 608. Therefore, at the port 604, the inner surface 612 of the outer tube 608 and the outer surface 614 of the inner tube 610 are adjacent to each other, thereby substantially preventing air from escaping between the inner tube 610 and the outer tube 608 at the port 604.

[0390] The distal section 624 of the inner tube 610 has an outer diameter much smaller than that of the port section 622. The distal section 624 of the inner tube 610 has an outer diameter much smaller than that of the outer tube 608. Therefore, at the distal end 606, the inner surface 612 of the outer tube 608 and the outer surface 614 of the inner tube 610 are spaced apart from each other.

[0391] The intermediate section 626 of the inner tube 610 has an outer diameter much smaller than that of the port section 622. The intermediate section 626 of the inner tube 610 has an outer diameter much smaller than that of the outer tube 608. Therefore, at the middle, the inner surface 612 of the outer tube 608 and the outer surface 614 of the inner tube 610 are spaced apart from each other.

[0392] The annular space 616 is provided in the space between the inner surface 612 of the outer tube 608 and the outer surfaces of the distal section 624 and the intermediate section 626.

[0393] Body 602 has an air inlet 628. Figure 9 In this example, the air inlets are multiple air inlet holes located in the wall of the outer tube 608. The air inlet holes are arranged in a row around the circumference of the outer tube 608.

[0394] The main body 602 has an air outlet 632. In Figure 9 In this example, air outlet 632 is a plurality of air outlet holes provided in the wall of inner tube 610.

[0395] The airflow passage is defined to extend between the air inlet 628 and the open end 604 of the body 602. The airflow passage extends from the air inlet 628 through the aerosol generation matrix compartment 618, through the air outlet 632 and to the open end 604.

[0396] exist Figure 9 In the example, the airflow passage includes a first airflow passage 630 and a second airflow passage 634.

[0397] A first airflow passage 630 extends between an air inlet 628 and an aerosol generation matrix compartment 618. The first airflow passage 630 passes through an annular space 616 defined between the inner surface 612 of the outer tube 608 and the outer surface 614 of the inner tube 610. In this manner, the air inlet 628 provides fluid communication between the aerosol generation matrix compartment 618 and the exterior of the article 600.

[0398] A second airflow passage 634 extends between the aerosol generation matrix compartment 618 and the open end 604 of the body 602. The second airflow passage 634 passes through the internal space defined by the inner tube 610, through the air outlet 632, and reaches the open end 604. In this way, the air outlet 632 provides fluid communication between the aerosol generation matrix compartment 618 and the open end 604 of the body 602.

[0399] The outer tube 608 includes an outer tube sealing member 636. In Figure 9 In this example, the outer tube sealing member 636 extends radially inward from the inner surface 612 of the outer tube 608. In other words, the outer tube sealing member 636 protrudes toward the inner tube 610. Figure 9 In this example, the outer tube sealing member 636 is an outer tube sealing disc integrally formed with the outer tube 608. The outer tube sealing disc extends circumferentially around the inner surface 612 of the outer tube 608.

[0400] The inner tube 610 includes an inner tube sealing member 638. Figure 9 In this example, the inner tube sealing member 638 extends radially outward from the outer surface 614 of the inner tube 610. In other words, the inner tube sealing member 638 protrudes toward the outer tube 608. Figure 9 In this example, the inner tube sealing member 638 is an inner tube sealing disc integrally formed with the inner tube 610. The inner sealing disc extends circumferentially around the outer surface 614 of the inner tube 610.

[0401] The outer tube 608 and the inner tube 610 are movable relative to each other between the first and second structures. Figure 9In this example, the outer tube 608 and the inner tube 610 are rotatably movable relative to each other about the longitudinal axis of the article 600. In other words, the outer tube 608 and / or the inner tube 610 can be displaced relative to each other by rotating the outer tube 608 and / or the inner tube 610 relative to the longitudinal axis of the article 600.

[0402] Figure 10 It shows along Figure 9 The cross section of line AA in the diagram.

[0403] Figure 10 The cross-section shows the outer tube 608 and the outer tube sealing member 636 extending radially inward from the outer tube 608. Figure 9 In this example, the outer tube sealing member 636 is an outer tube sealing disc. The outer tube sealing disc is a segmented disc with openings 640 between its segments. The outer tube sealing member 636 is integrally formed with the outer tube 608. Therefore, when the outer tube 608 rotates about the longitudinal axis of the article 600, the outer tube sealing member 636 rotates. Rotating the outer tube sealing member 636 causes the segments of the segmented disc to rotate, and thus changes the size of the openings 640.

[0404] Figure 11 It shows along Figure 9 The cross-section of line BB in the middle. Figure 11 In the middle, the outer tube 608 and the inner tube 610 are in the second structure.

[0405] Figure 11 The cross-section shows the inner tube 610 and the inner tube sealing member 638 extending radially outward from the inner tube 610. Figure 9 In this example, the inner tube sealing member 638 is an inner tube sealing disc. The inner tube sealing disc is a segmented disc with openings 642 between its segments. The inner tube sealing member 638 is integrally formed with the inner tube 610. Therefore, the inner tube sealing member 638 rotates when the inner tube 610 rotates about the longitudinal axis of the article 600. Rotating the inner tube sealing member 638 causes the segments of the segmented disc to rotate, and thus changes the size of the openings 642.

[0406] exist Figure 11 In the second configuration, the outer tube 608 and the inner tube 610 are arranged in a second configuration. In this second configuration, the outer tube 608 and the inner tube 610 rotate about the longitudinal axis of the article 600, such that the outer tube sealing member 636 and the inner tube sealing member 638 are in the same radial position. Therefore, in Figure 11In the view, the outer tube sealing member 636 is concealed behind the inner tube sealing member 638. When the outer tube sealing member 636 and the inner tube sealing member 638 are in the same radial position, the opening 640 in the outer tube sealing disc and the opening 642 in the inner tube sealing disc are aligned with each other. The alignment of the openings 640 and 642 allows air to flow through the airflow passage. In particular, the alignment of the openings 640 and 642 allows air to flow through the first airflow passage 630 between the air inlet 628 and the aerosol generation matrix compartment 618.

[0407] Figure 12 It shows along Figure 9 The cross-section of line BB in the middle. Figure 12 In the middle, the outer tube 608 and the inner tube 610 are in the first structure.

[0408] In the first configuration, the outer tube 608 and the inner tube 610 are positioned such that the outer tube sealing member 636 and the inner tube sealing member 638 cooperate with each other to substantially prevent airflow through the airflow passage. Specifically, in the first configuration, the outer tube 608 and the inner tube 610 are positioned such that the outer tube sealing member 636 and the inner tube sealing member 638 cooperate with each other to substantially prevent airflow through the first airflow passage 630. Figure 12 In one example, in the first configuration, the outer tube sealing member 636 and the inner tube sealing member 638 are adjacent to each other to create a substantially airtight seal. The seal created by the outer tube sealing member 636 and the inner tube sealing member 638 substantially prevents air from flowing between the air inlet 628 and the aerosol generating matrix compartment 618.

[0409] Specifically, in Figure 9 In this example, when in the first configuration, the outer tube sealing member 636 and the inner tube sealing member 638 are in different radial positions. In the first configuration, the opening 640 in the outer tube sealing disc 636 is substantially blocked by the inner tube sealing disc 638, and the opening 642 in the inner tube sealing disc 638 is substantially blocked by the outer tube sealing disc 636. Blocking the airflow through the openings 640 and 642 closes the airflow passage and substantially prevents air from flowing between the air inlet 628 and the aerosol generation matrix compartment 618.

[0410] In addition, Figure 9 In this example, when in the first configuration, the opening 642 in the inner tube sealing disc 638 is blocked by the outer tube sealing disc 636, further sealing the airflow passage. Specifically, when in the first configuration, the opening 642 in the inner tube sealing disc 638 is blocked by the outer tube sealing disc 636, sealing the second airflow passage 634. Sealing the second airflow passage 634 essentially prevents air from flowing between the aerosol generation matrix compartment 618 and the open end 604 of the body 602.

[0411] Figure 13It shows along Figure 9 The cross-section of line BB in the middle. Figure 13 In the middle, the outer tube 608 and the inner tube 610 move, so that they are in a structure between the first structure and the second structure.

[0412] When the outer tube 608 and the inner tube 610 are in the configuration between the first and second configurations, the outer tube sealing disc 636 is partially aligned with the opening 642 in the inner tube sealing disc 638, thus partially blocking the opening 642. This partial blocking of the opening 642 restricts airflow through it. This restriction of airflow through the opening 642 limits airflow through the airflow passage and reduces airflow between the air inlet 628 and the aerosol generation matrix compartment 618, and between the aerosol generation matrix compartment 618 and the open end 604 of the body 602.

[0413] exist Figure 13 In this example, restricting the airflow through opening 642 restricts the airflow through the first airflow passage 630 and the airflow through the second airflow passage 634. Restricting the airflow through the second airflow passage 634 reduces the airflow between the aerosol generation matrix compartment 618 and the open end 604 of the body 602.

[0414] The outer tube 608 and the inner tube 610 are rotatable relative to each other about the longitudinal axis of the article 600 in order to adjust the proportion of the opening 642 blocked by the inner tube sealing disc 638. Adjusting the proportion of the opening 642 blocked by the inner tube sealing disc 638 allows for adjustment of the restriction on airflow through the airflow passage.

[0415] Therefore, the suction resistance of the product 600 can be adjusted by rotating the outer tube 608 and the inner tube 610 relative to each other about the longitudinal axis of the product 600.

[0416] Figure 14 A schematic diagram of a fifth example of an article 700 for generating an inhalable aerosol upon heating is shown.

[0417] Article 700 has a body 702. The body 702 has an opening 704 and a distal end 706. In this example, the opening 704 of the body 702 is open, and the distal end 706 of the body 702 is closed. In other words, air can flow out of the body 702 at the opening 704, but air cannot easily flow out of the distal end 706 of the body 702.

[0418] The body 702 has an outer tube 708 and an inner tube 710. The outer tube 708 has an inner surface 712, and the inner tube 710 has an outer surface 714. The inner tube 710 is disposed inside the outer tube 708. A space 716 is defined between the inner surface 712 of the outer tube 708 and the outer surface 714 of the inner tube 710. Figure 14 In this example, the space is a toroidal space 716.

[0419] The body 702 has an aerosol generation matrix compartment 718 positioned toward the distal end 706 of the body 702. Figure 14 In this example, the aerosol generation matrix compartment 718 is defined by an annular space 716 at the closed distal end 706 of the body 702. The aerosol generation matrix compartment 718 is a cavity suitable for holding a certain amount of aerosol generation matrix, such as solid aerosol generation matrix. In this example, the aerosol generation matrix compartment 718 holds a certain amount of solid aerosol generation matrix 720.

[0420] The outer tube 708 has a generally cylindrical shape.

[0421] The inner tube 710 can be formed by one or more sections. Figure 14 In this example, the inner tube 710 has an end section 722, a distal section 724, and an intermediate section 726. The three sections 722, 724, and 726 of the inner tube 708 are formed separately and connected together to form a single piece. In this example, the end section 722 is located at the end 704 of the body 702, the distal section 724 is located at the distal end 706 of the body 702, and the intermediate section 726 extends between the end section 722 and the distal section 724.

[0422] The port section 722 of the inner tube 710 has an outer diameter that is substantially the same as the inner diameter of the outer tube 708. Therefore, at the port 704, the inner surface 712 of the outer tube 708 and the outer surface 714 of the inner tube 710 are adjacent to each other, thereby substantially preventing air from escaping between the inner tube 710 and the outer tube 708 at the port 704.

[0423] The distal section 724 of the inner tube 710 has an outer diameter much smaller than that of the port section 722. The distal section 724 of the inner tube 710 has an outer diameter much smaller than that of the outer tube 708. Therefore, at the distal end 706, the inner surface 712 of the outer tube 708 and the outer surface 714 of the inner tube 710 are spaced apart from each other.

[0424] The intermediate section 726 of the inner tube 710 has an outer diameter much smaller than that of the port section 722. The intermediate section 726 of the inner tube 710 has an outer diameter much smaller than that of the outer tube 708. Therefore, at the middle, the inner surface 712 of the outer tube 708 and the outer surface 714 of the inner tube 710 are spaced apart from each other.

[0425] The annular space 716 is provided in the space defined between the inner surface 712 of the outer tube 708 and the outer surfaces of the distal section 724 and the intermediate section 726.

[0426] The main body 702 has an air inlet 728. Figure 14In this example, the air inlets are multiple air inlet holes located in the wall of the outer tube 708. The air inlet holes are arranged in a row around the circumference of the outer tube 708.

[0427] The main body 702 has an air outlet 732. In Figure 14 In one example, the air outlet 732 is an air outlet hole configured to pass through the end wall of the inner tube 710 and be positioned toward the distal end 706 of the body 702.

[0428] The airflow passage is defined to extend between the air inlet 728 and the open end 704 of the body 702. The airflow passage extends from the air inlet 728 through the aerosol generation matrix compartment 718, through the air outlet 732 and to the open end 704.

[0429] exist Figure 14 In the example, the airflow passage includes a first airflow passage 730 and a second airflow passage 734.

[0430] A first airflow passage 730 extends between an air inlet 728 and an aerosol generation matrix compartment 718. The first airflow passage 730 passes through an annular space 716 defined between the inner surface 712 of the outer tube 708 and the outer surface 714 of the inner tube 710. In this way, the air inlet 728 provides fluid communication between the aerosol generation matrix compartment 718 and the exterior of the article 700.

[0431] The second airflow passage 734 extends between the aerosol generation matrix compartment 718 and the open end 704 of the body 702. The second airflow passage 734 passes through the internal space defined by the inner tube 710, through the air outlet 732, and reaches the open end 704. In this way, the air outlet 732 provides fluid communication between the aerosol generation matrix compartment 718 and the open end 704 of the body 702.

[0432] The outer tube 708 includes an outer tube sealing member 736. Figure 14 In this example, the outer tube sealing member 736 extends radially inward from the inner surface 712 of the outer tube 708. In other words, the outer tube sealing member 736 protrudes toward the inner tube 710. Figure 14 In this example, the outer tube sealing member 736 is an outer tube sealing disc integrally formed with the outer tube 708. The outer tube sealing disc extends circumferentially around the inner surface 712 of the outer tube 708.

[0433] The outer tube 708 has an end face sealing member 744. Figure 14 In this example, the end face sealing member 744 is positioned on the end face of the outer tube 708 toward the distal end 706 of the body 702. The end face sealing member 744 protrudes toward the port end 704 of the body 702 along the longitudinal axis of the article 700. The end face sealing member 744 is offset from the center of the end wall of the outer tube 708.

[0434] The inner tube 710 includes an inner tube sealing member 738. Figure 14 In this example, the inner tube sealing member 738 extends radially outward from the outer surface 714 of the inner tube 710. In other words, the inner tube sealing member 738 protrudes toward the outer tube 708. Figure 14 In this example, the inner tube sealing member 738 is an inner tube sealing disc integrally formed with the inner tube 710. The inner sealing disc extends circumferentially around the outer surface 714 of the inner tube 710.

[0435] The outer tube 708 and the inner tube 710 are movable relative to each other between the first and second structures. Figure 14 In this example, the outer tube 708 and the inner tube 710 are rotatably movable relative to each other about the longitudinal axis of the article 700. In other words, the outer tube 708 and / or the inner tube 710 can be displaced relative to each other by rotating the outer tube 708 and / or the inner tube 710 relative to the longitudinal axis of the article 700.

[0436] exist Figure 14 and 15 In the example, the outer tube sealing member 736 and the inner tube sealing member 738 have the same characteristics as described above. Figure 10 , 11 The same constructions are described in 12 and 13.

[0437] Specifically, the outer tube sealing member 736 extends radially inward from the outer tube 708. Figure 14 and 15 In this example, the outer tube sealing member 736 is an outer tube sealing disc. The outer tube sealing disc is a segmented disc with openings between its sections. The outer tube sealing member 736 is integrally formed with the outer tube 708. Therefore, when the outer tube 708 rotates about the longitudinal axis of the article 700, the outer tube sealing member 736 rotates. Rotating the outer tube sealing member 736 causes the sections of the segmented disc to rotate, and thus changes the size of the openings.

[0438] Specifically, the inner tube sealing member 738 extends radially outward from the inner tube 710. Figure 14 and 15 In this example, the inner tube sealing member 738 is an inner tube sealing disc. The inner tube sealing disc is a segmented disc with openings between its sections. The inner tube sealing member 738 is integrally formed with the inner tube 710. Therefore, the inner tube sealing member 738 rotates when the inner tube 710 rotates about the longitudinal axis of the article 700. Rotating the inner tube sealing member 738 causes the sections of the segmented disc to rotate, and thus changes the size of the openings.

[0439] exist Figure 14 In the example, the outer tube 708 and the inner tube 710 are in the first configuration.

[0440] In the first configuration, the outer tube 708 and the inner tube 710 are positioned such that the outer tube sealing member 736 and the inner tube sealing member 738 cooperate with each other to substantially prevent air from flowing through the airflow passage.

[0441] Specifically, in the first configuration, the outer tube 708 and the inner tube 710 are positioned such that the outer tube sealing member 736 and the inner tube sealing member 738 cooperate with each other to substantially prevent air from flowing through the first airflow passage 730.

[0442] exist Figure 14 and 15 In the example, in the first configuration, the outer tube sealing member 736 and the inner tube sealing member 738 are adjacent to each other to close the opening and create a substantially airtight seal. The seal created by the outer tube sealing member 736 and the inner tube sealing member 738 substantially prevents air from flowing between the air inlet 728 and the aerosol generating matrix compartment 718.

[0443] In addition, Figure 14 In one example, in the first configuration, the outer tube 708 and the inner tube 710 are positioned such that the end-face sealing member 744 cooperates with the inner tube 710 to further prevent airflow through the airflow passage. Specifically, in the first configuration, the outer tube 708 and the inner tube 710 are positioned such that the end-face sealing member 744 substantially blocks airflow through the air outlet 732. Blocking airflow through the air outlet 732 substantially prevents air from flowing between the aerosol generation matrix compartment 718 and the exterior of the article 700. In other words, blocking airflow through the air outlet 732 substantially prevents air from flowing along the second airflow passage 734.

[0444] Figure 15 A schematic diagram of article 700 is shown with the outer tube 708 and inner tube 710 in the second configuration. Article 700 has the same characteristics as described above. Figure 14 The same features are described.

[0445] In order to move the outer tube 708 and the inner tube 710 between the first configuration and the second configuration, the user can, for example, rotate the inner tube 710 longitudinally relative to the outer tube 708.

[0446] Rotating the inner tube 710 relative to the outer tube 708 causes the inner tube sealing member 738 to rotate about the longitudinal axis of the article 700. Rotating the inner tube sealing member 738 aligns the opening in the inner tube sealing member 738 with the opening in the outer tube sealing member 736, thereby opening the airflow passage between the air inlet 728 and the aerosol generation matrix compartment 718.

[0447] Simultaneously, rotating the inner tube 710 relative to the outer tube 708 moves the air outlet 732 away from the end wall sealing member 744, thereby opening the airflow passage between the aerosol generation matrix compartment 718 and the outside of the article 700.

[0448] Therefore, by rotating the inner tube 710 relative to the outer tube 708 about the longitudinal axis of the product 700, the airflow through the airflow passage can be controlled.
