Description

Technical Field

[0001] The present application relates to the technical field of aerosol generation, and particularly relates to an aerosol generating device, an aerosol generating system and a first aerosol article. Background Art

[0002] An aerosol generating device is a device that can cause an aerosol generating article to generate an aerosol for a user to inhale when heated without burning. The aerosol generating article includes a substrate section and a mouthpiece. The aerosol generated by the substrate section can flow into the user's mouth through the mouthpiece under the user's suction. In some exemplary prior arts, there is an aerosol generating device, which includes a first module for causing the aerosol generating article to generate a first aerosol and a second module for causing a liquid substrate to generate a second aerosol. Along the direction of the airflow, the second module is arranged upstream of the first module, so that the second aerosol needs to flow into the substrate section of the aerosol generating article and then be inhaled into the user's mouth through the mouthpiece of the aerosol generating article.

[0003] However, the second aerosol has a relatively high humidity. After flowing into the substrate section, it will wet the substrate in the substrate section, such as tobacco, which will not only cause the substrate to adhere and greatly increase the internal draw resistance, but also is not conducive to the substrate generating an aerosol under normal baking, resulting in a poor user experience.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0055] The terms "first", "second", and "third" in the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity or order of the indicated technical features. All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship or movement situation between components in a specific posture (as shown in the drawings).

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0056] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0057] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element, or there may be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0058] Please refer to Figures 1 - 3 , some embodiments of the present application provide an aerosol generating device 100, which can be used in combination with a first aerosol article 200 such that the first aerosol article 200 generates a first aerosol.

[0059] The first aerosol article 200 includes a mouthpiece 210, a connection section 220, and an aerosol generating matrix section 230 capable of generating a first aerosol. The connection section 220 is located between the mouthpiece 210 and the aerosol generating matrix section 230 and is used to direct the first aerosol to the mouthpiece 210. The mouthpiece 210 can be held by a user's mouth, and the user can suck the first aerosol by sucking on the mouthpiece 210. An air hole 240 fluidly connecting the mouthpiece 210 is formed in the side wall of the connection section 220, and air flow outside the first aerosol article can enter the interior of the connection section 220 through the air hole 240 and then enter the mouthpiece 210.

[0060] The aerosol generating matrix section 230 includes an aerosol generating matrix.

[0061] As used herein, the term "aerosol generating matrix" refers to a matrix capable of releasing volatile substances to form an inhalable aerosol therefrom. The aerosol generating matrix may include a tobacco-containing material that contains volatile tobacco flavor compounds released from the substrate upon heating. Specifically, the aerosol generating matrix may be a tobacco-containing aerosol generating matrix, preferably a solid tobacco-containing aerosol generating matrix. Alternatively, the aerosol generating matrix may include a non-tobacco material. The aerosol generating matrix may also include an aerosol former. Examples of suitable aerosol formers are glycerol and propylene glycol.

[0062] Optionally, the aerosol generating matrix may contain additional tobacco or non-tobacco volatile flavor compounds released when the aerosol generating matrix is heated. The aerosol generating matrix may also contain microcapsules, such as those containing additional tobacco or non-tobacco volatile flavor compounds, and such microcapsules may melt during heating of the solid aerosol generating matrix.

[0063] The first aerosol article 200 may generally be a longitudinally extending rod-shaped structure. The mouthpiece 210 may be disposed adjacent to the proximal end of the first aerosol article 200. The aerosol-generating substrate section 230 may be disposed adjacent to the distal end of the first aerosol article 200.

[0064] It should be noted that the aerosol-generating device provided in the present application can be used in combination with one or more different aerosol articles. For other aerosol articles having a mouthpiece and capable of being used in combination with the aerosol-generating device provided in the present application, the air holes may not be provided on the side wall of the connecting section.

[0065] Please refer to Figure 1 , the aerosol-generating device 100 provided in the application includes a first module 1, a second module 2, and a third module 3.

[0066] The first module 1 includes a first sealing ring 111 and a first receiving cavity 112. The first receiving cavity 112 is used to receive a part of the first aerosol article 200, for example, it can receive the part of the connecting section 220 where the air holes 240 are provided on the side wall. The proximal end of the first module 1 is open for the first aerosol article 200 to enter the first receiving cavity 112. The first sealing ring 111 is disposed at the proximal end of the first receiving cavity 112.

[0067] The aerosol-generating device 100 includes an insertion port 41 for the first aerosol article 200 to be inserted into the first receiving cavity 112. The proximal end of the first receiving cavity 112 is the end of the first receiving cavity 112 closer to the insertion port 41. When the aerosol-generating device 100 is used in combination with the first aerosol article 200, the mouthpiece 210 of the first aerosol article 200 and the air holes 240 of the first aerosol article 200 are located on opposite sides of the first sealing ring 111, or the insertion port 41 and the first receiving cavity 112 are located on opposite sides of the first sealing ring 111.

[0068] The second module 2 includes a second receiving cavity 21 and a first component 22. The second receiving cavity is used to receive a part of the first aerosol article 200, for example, it can receive at least a part of the aerosol-generating substrate section 230. The first component 22 is used to generate a first aerosol from the aerosol-generating substrate section 230. The proximal end of the second module 2 is open for a part of the first aerosol article 200 to pass through the first receiving cavity 112 and then enter the second receiving cavity 21. In other words, a part of the first aerosol article 200 needs to pass through the first receiving cavity 112 before it can enter the second receiving cavity 21 and be held there. And when the aerosol-generating device 100 is used in combination with the first aerosol article 200, a part of the first aerosol article 200 is held in the second receiving cavity 21, a part is held in the first receiving cavity 112, and the mouthpiece 210 may be located outside the aerosol-generating device 100 for the user to hold in the mouth.

[0069] The first sealing ring 111 is configured to sealingly surround and connect the first aerosol article 200 when a part of the first aerosol article 200 is received in the second receiving cavity 21. In other words, the inner diameter of the first sealing ring 111 is smaller than the outer diameter of the first aerosol article 200, so that the first sealing ring 111 can elastically clamp the first aerosol article 200 located inside it. Thus, when the aerosol generating device 100 is used in combination with the first aerosol article 200, the first sealing ring 111 can prevent air outside the aerosol generating device 100 from entering the first receiving cavity 112 through the insertion port 41, and further prevent air outside the aerosol generating device 100 from entering the air holes 240 on the connection section 220 through the insertion port 41. At the same time, when the aerosol generating device 100 is used in combination with the first aerosol article 200, the first sealing ring 111 can clamp the first aerosol article 200 to prevent the mouthpiece 210 of the first aerosol article 200 from moving longitudinally when being held and sucked by the user's mouth.

[0070] The third module 3 includes a third receiving cavity 31 for receiving the second aerosol article and a second component 32 for generating a second aerosol from the second aerosol article. The third module 3 further includes an air guiding channel 33 for guiding the second aerosol to the first receiving cavity 112.

[0071] The second aerosol article may contain an aerosol generating substrate. The aerosol generating substrate contained in the second aerosol article may be the same as the aerosol generating substrate contained in the first aerosol article 200, so the first aerosol and the second aerosol may have the same flavor. The aerosol generating substrate contained in the second aerosol article may be the same as the aerosol generating substrate contained in the first aerosol article 200, so the first aerosol and the second aerosol may have different flavors.

[0072] The aerosol generating substrate contained in the second aerosol article may include a solid aerosol generating substrate.

[0073] The second aerosol article may contain a liquid preparation. The liquid preparation may contain a liquid containing a tobacco-containing substance with volatile tobacco flavor components, and may also contain a liquid of a non-tobacco substance. The liquid preparation may contain water, a medicinal liquid, a solvent, ethanol, a plant extract, a fragrance, a flavoring agent, or a vitamin mixture, etc. The fragrance may include menthol, peppermint, spearmint oil, various fruit flavor components, etc., but is not limited thereto. The flavoring agent may contain components that can provide various scents or flavors to the user. The vitamin mixture may be a mixture containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but is not limited thereto.

[0074] The second aerosol can flow into the first accommodation cavity 112 under the guidance of the air guiding channel 33, and then can enter the connection section 220 through the air holes 240 provided on the connection section 220, and then is inhaled into the oral cavity by the user through the mouthpiece 210.

[0075] Among them, there can be one or more air holes 240. When there are multiple air holes 240, the multiple air holes 240 can be arranged in a discrete array, a discrete ring, multiple discrete rings, a discrete spiral, multiple discrete spirals, a straight line extending longitudinally, multiple straight lines extending longitudinally, etc., and the multiple air holes 240 can be evenly distributed on part or all of the side walls of the connection section 220.

[0076] In some embodiments, a mixing cavity 223 is provided inside the connection section 220 of the first aerosol article 200. The mixing cavity 223 is in fluid communication with the mouthpiece 210, the aerosol generating matrix section 230 and the air holes 240 at the same time. Thus, the first aerosol and the second aerosol can be mixed in the mixing cavity 223, and then the mixed air flow is inhaled into the oral cavity by the user through the mouthpiece 210.

[0077] In some embodiments (not shown), the connection section of the first aerosol article has a first chamber and a second chamber separated from each other inside. The first chamber is in fluid communication with the mouthpiece and the aerosol generating matrix section, and the second chamber is in fluid communication with the mouthpiece and the air holes. Thus, the first aerosol and the second aerosol can be mixed in the mouthpiece, or the first aerosol and the second aerosol can be inhaled into the oral cavity by the user through the mouthpiece without mixing with each other.

[0078] The larger the area of the air holes 240, the easier it is for the second aerosol to enter the connection section 220. The density of the second aerosol is greater than that of air, and the second aerosol will condense to form condensate when the temperature decreases. Therefore, if the area of the air holes 240 is too small, the surface tension of the condensate will block the air holes 240, thus preventing the subsequent second aerosol from entering the connection section 220. In order to prevent the air holes 240 from being blocked, in some embodiments of the present application, the area of the air holes 240 can be between 0.3 mm2 and 30 mm2, preferably the area of the air holes 240 is between 1.5 mm2 and 6 mm2.

[0079] In some embodiments, reference can be made to Figure 1 and Figure 4, the first module 1 further includes a second sealing ring 113 disposed at the distal end of the first accommodation cavity 112. The distal end of the first accommodation cavity 112 may be the end of the first accommodation cavity 112 closer to the second module 2. The second sealing ring 113 is configured to sealingly surround and connect the first aerosol article 200 when a part of the first aerosol article 200 is accommodated in the second accommodation cavity 21. In other words, the inner diameter of the second sealing ring 113 is smaller than the outer diameter of the first aerosol article 200, so that the second sealing ring 113 can elastically clamp the second aerosol article 200 located inside it. Thus, when the aerosol generating device 100 is used in combination with the first aerosol article 200, the second sealing ring 113 can prevent air flow from entering the first accommodation cavity 112 from the second module 2, and prevent the air flow between the second sealing ring 113 and the second module 2 from entering the first accommodation cavity 112. At the same time, when the aerosol generating device 100 is used in combination with the first aerosol article 200, the second sealing ring 113 can clamp the first aerosol article 200 to prevent the mouthpiece 210 of the first aerosol article 200 from moving longitudinally when being held and sucked by the user's mouth.

[0080] The inner diameters of both the first sealing ring 111 and the second sealing ring 113 are smaller than the outer diameter of the first aerosol article 200, and the first sealing ring 111 and the second sealing ring 113 are spaced apart longitudinally. Thus, the first sealing ring 111 and the second sealing ring 113 can double-clamp the aerosol article that can be used in combination with the aerosol generating device 100 and can be partially accommodated in the first accommodation cavity 112. The aerosol article includes, but is not limited to, the first aerosol article 200.

[0081] Reference may be made to Figure 1 , the air holes 240 on the side wall of the first aerosol article 200 are located in the first accommodation cavity 112, so the air holes 240 on the side wall of the first aerosol article 200 are located between the first sealing ring 111 and the second sealing ring 113.

[0082] Further, reference may be made to Figure 1 、 Figure 3 and Figure 4The first module 1 further includes a vent 1151, which is located between the first sealing ring 111 and the second sealing ring 113. The vent 1151 fluidically connects the first accommodating chamber 112 and the air guide channel 33. Therefore, when the aerosol generating device 100 is used in conjunction with the first aerosol product 200, the airflow entering the first accommodating chamber 112 is primarily the second aerosol. This prevents the second aerosol flowing into the first accommodating chamber 112 from leaking out of the first accommodating chamber 112 through the aerosol generating device 100, and also prevents the second aerosol from being diluted by external air and other airflows other than the first aerosol. It should be noted that the airflow in the first accommodating chamber 112 may include airflow within the first accommodating chamber 112 but not flowing into the first aerosol product 200, or may include airflow within the portion of the first aerosol product 200 located within the first accommodating chamber 112.

[0083] In some embodiments, reference may be made to Figure 2 There are multiple air holes 240, and some of the multiple air holes 240 can be staggered with the vent holes 1151. To ensure that the second aerosol can enter the connecting section 220 through the multiple air holes 240, the cross-section of the first accommodating cavity 112 can be larger than the cross-sectional area of the first aerosol product 200. Alternatively, the first module 1 includes a first tubular body 114 that defines at least a portion of the first accommodating cavity 112, and the inner diameter of the portion of the first tubular body 114 surrounding the first accommodating cavity 112 can be larger than the outer diameter of the connecting section 220. Thus, when the connecting section 220 of the first aerosol product 200 is located in the first accommodating cavity 112, a gap exists between the sidewall of the connecting section 220 and the inner wall of the first tubular body 114, preventing the sidewall of the first tubular body 114 from blocking the air holes 240.

[0084] In some embodiments, reference may be made to Figure 1 The air hole 240 and the second sealing ring 113 are spaced apart in the longitudinal direction. Thus, a portion of the side wall of the connecting section 220, a portion of the inner wall of the first tubular body 114, and the second sealing ring 113 can collectively form a liquid accumulation space within the first accommodating chamber 112 to collect condensate formed by the second aerosol in the gap between the first tubular body 114 and the connecting section 220. This prevents the condensate from clogging the air hole 240 and affecting the flow of the second aerosol into the connecting section 220. The spacing between the air hole 240 and the second sealing ring 113 can be greater than or equal to 1 mm.

[0085] In some embodiments, reference may be made to Figure 3 and Figure 4, the first module 1 includes a first tubular body 114 that defines at least a partial boundary of the first accommodation cavity 112, and the first sealing ring 111 and the second sealing ring 113 can both be connected to the first tubular body 114. Alternatively, the first module 1 includes a flexible article 11, which includes the first sealing ring 111, the second sealing ring 113, and the first tubular body 114 that defines at least a partial boundary of the first accommodation cavity 112, and the first sealing ring 111 and the second sealing ring 113 can be integrally formed with the first tubular body 114. The flexible article 11 has elasticity. The flexible article 11 can be made of silica gel.

[0086] Among them, the vent hole 1151 can be provided on the side wall of the first tubular body 114.

[0087] The first tubular body 114 can extend longitudinally, and the first sealing ring 111 and the second sealing ring 113 are arranged at intervals from each other longitudinally. The longitudinal distance between the first sealing ring 111 and the second sealing ring 113 can be less than or equal to the longitudinal extension length of the first tubular body 114; alternatively, the longitudinal extension depth of the first accommodation cavity 112 can be less than or equal to the longitudinal extension length of the first tubular body 114. The longitudinal distance between the first sealing ring 111 and the second sealing ring 112, or the longitudinal extension depth of the first accommodation cavity 112, can be less than the length of the connecting section 220. The longitudinal length of the connecting section 220 of the first aerosol article 200 can be between 15 mm and 40 mm. For example, the longitudinal length of the connecting section 220 of the first aerosol article 200 can be about 26 mm. The longitudinal distance between the first sealing ring 111 and the second sealing ring 113, or the longitudinal extension depth of the first accommodation cavity 112, can be between 2 mm and 5 mm, including 2 mm and 5 mm. For example, the longitudinal distance between the first sealing ring 111 and the second sealing ring 113, or the longitudinal extension depth of the first accommodation cavity 112, can be about 3.5 mm.

[0088] In some embodiments, the first aerosol article 200 includes a packaging 250 disposed on the periphery, the aerosol - generating substrate is located inside the packaging 250, and the packaging 250 is formed of any suitable material or combination of materials. Preferably, the packaging 250 is cigarette paper.

[0089] In some embodiments, reference may be made to Figure 2 , the connecting section 220 can include a support section 221 adjacent to the aerosol - generating substrate section 230 and a cooling section 222 adjacent to the mouthpiece 210. Along the air - flow direction, the support section 221 is located upstream of the cooling section 222.

[0090] The support section 221 has a support element 2211 disposed inside the packaging 250. The support element 2211 can be formed of any suitable material or combination of materials. For example, the support element 2211 can be formed of one or more materials selected from the group consisting of: cellulose acetate; cardboard; crepe paper, such as crepe heat-resistant paper or crepe parchment paper; and polymeric materials, such as low density polyethylene (LDPE). In a preferred embodiment, the support element 2211 is formed of cellulose acetate. The support element 2211 can include a hollow tubular element. In a preferred embodiment, the support element 2211 includes a hollow cellulose acetate tube. The support element 2211 can have a length between about 5 millimeters and about 15 millimeters. In a preferred embodiment, the support element 2211 has a length of about 8 millimeters.

[0091] The support element 2211 is capable of outwardly supporting the packaging 250, helping to prevent the first aerosol article 200 from bending.

[0092] The cooling section 222 is located between the support section 221 and the mouthpiece 210. The first aerosol generated by the aerosol generation matrix flows into the cooling section 222 via the support section 221, and then after the temperature is appropriately reduced in the cooling section 222, it flows into the mouthpiece 210 to prevent the mouthpiece 210 or the user from inhaling the first aerosol and burning their mouth. The longitudinal length of the cooling section 222 can be greater than the length of the support section 221.

[0093] Air holes 240 can be opened on the side wall of the cooling section 222, wherein the side wall of the cooling section 222 includes the packaging 250. In some embodiments, reference can be made to Figure 1 , when the first aerosol article 200 is used in combination with the aerosol generating device 100, a part of the cooling section 222 is located in the first receiving cavity 112 and a part is located outside the aerosol generating device 100, thereby helping to further reduce the temperature of the first aerosol before it flows into the mouthpiece 210. Among them, the first sealing ring 111 can be hermetically connected around the side wall of the cooling section 222. In some embodiments, reference can be made to Figure 1 , a part of the support section 221 is located in the first receiving cavity 112, and the second sealing ring 113 can be hermetically connected around the side wall of the support section 221 to prevent the connecting section 220 from deforming under the tightening action of the first sealing ring 111 and the second sealing ring 113.

[0094] Preferably, when the first aerosol article 200 is used in combination with the aerosol generating device 100, the air holes 240 are located between the support section 221 and the first sealing ring 111, and the longitudinal distance between the first sealing ring 111 and the support element 2211 is less than 5 mm. More preferably, the longitudinal distance between the first sealing ring 111 and the support element 2211 is between 1 mm and 3 mm.

[0095] Preferably, when the first aerosol article 200 is used in combination with the aerosol generating device 100, the support element 2211 faces the end of the cooling section 222, that is, the proximal end of the support element 2211 is located in the first receiving cavity 112, and the longitudinal distance between the proximal end of the support element 2211 and the second sealing ring 113 is between 1 mm and 3 mm.

[0096] In some embodiments, after the second aerosol enters the mixing cavity 223 and mixes with the first aerosol, the temperature of the first aerosol can be reduced.

[0097] The heat released by the first aerosol in the connecting section 220 in the first receiving cavity 112 can prevent the second aerosol from condensing in the first aerosol article 200 and prevent the second aerosol from condensing in the air holes 240, thereby preventing the condensate formed by the condensation of the second aerosol from blocking the air holes 240.

[0098] In some embodiments, the first sealing ring 111 is provided on the proximal end of the first tubular body 114. The second sealing ring 113 can be provided on the distal end of the first tubular body 114.

[0099] Please refer to Figure 4 , the second sealing ring 113 can be provided inside the first tubular body 114, so that the second sealing ring 113 is located between the proximal end and the distal end of the first tubular body 114. Based on this, there can be two chambers inside the first tubular body 114, one chamber is the aforementioned first receiving cavity 112, and the other chamber can be called the fourth receiving cavity 116, and a part of the first aerosol article 200 can be accommodated in the fourth receiving cavity 116. The second sealing ring 113 can be located between the fourth receiving cavity 116 and the first receiving cavity 112. The cross-sectional area of the first receiving cavity 112 can be greater than or equal to the cross-sectional area of the fourth receiving cavity 116. Both the first receiving cavity 112 and the fourth receiving cavity 116 can be circular chambers. The diameter of the first receiving cavity 112 can be greater than or equal to the diameter of the fourth receiving cavity 116. The thickness of the side wall of the first tubular body 114 defining the first receiving cavity 112 can be less than or equal to the thickness of the side wall of the first tubular body 114 defining the fourth receiving cavity 116. The inner diameter of the fourth receiving cavity 116 can be greater than the outer diameter of the first aerosol article 200.

[0100] In some embodiments, reference can be made to Figures 3 - 5 , the first module 1 includes a second tubular body 115 for defining at least part of the boundary of the ventilation hole 1151, and the second tubular body 115 is provided on the side wall of the first tubular body 114 and is sealingly connected to the third module 3.

[0101] The extending direction of the second tubular body 115 can be perpendicular to the extending direction of the first tubular body 114. The second tubular body 115 can extend transversely.

[0102] The second tubular body 115 may be integrally formed with the first tubular body 114.

[0103] In some embodiments, reference may be made to Figure 3 , Figure 6 and Figure 7 , the third module 3 includes an air duct 35 for defining at least part of the boundary of the air guiding channel 33, and the end of the air duct 35 is inclined and abuts against the end of the second tubular body 115. Therefore, the contact area between the air duct 35 and the second tubular body 115 can be increased, which helps to prevent the leakage of the second aerosol from between the air duct 115 and the second tubular body 115. Compared with the way of fitting connection between the air duct 35 and the second tubular body 115, it also helps to simplify the connection way between the air duct 35 and the second tubular body 115, and helps to simplify the combination process of the first module 1 and the third module 3.

[0104] When both the air duct 35 and the second tubular body 115 are made of materials that are not easily deformed, such as PEEK materials, the aerosol generating device 100 further includes a seal for providing a seal between the air duct 35 and the second tubular body 115. When the flexible article 11 includes the second tubular body 115, the second tubular body 115 can be elastically connected to the third module 3 and can be hermetically connected to the third module 3 based on the elastic connection to prevent the leakage of the second aerosol.

[0105] Furthermore, reference may be made to Figure 4 and Figure 5 , an elastic annular rib 1152 is provided on the end of the second tubular body 115, and the annular rib 1152 elastically abuts against the end of the air duct 35, so that the second tubular body 115 is hermetically connected to the air duct 35.

[0106] In some embodiments, reference may be made to Figure 4 , the first module 1 includes an integrally formed flexible article 11 and further includes a first bracket 12 having a through hole. The hardness of the first bracket 12 is greater than that of the flexible article 11, so that the first bracket 12 is relatively difficult to deform compared with the flexible article 11. The flexible article 11 is connected to the first bracket 12, and at least a part of the first tubular body 114 is located in the through hole. The first bracket 12 is used to support the flexible article 11 so that the first sealing ring 111 and the second sealing ring 113 can closely abut against the first aerosol article 200, and the first sealing ring 111 and the second sealing ring 113 can hermetically connect the first aerosol article 200 in a surrounding manner.

[0107] In some embodiments, reference may be made to Figure 3 and Figure 6, the aerosol generating device 100 further includes an end cap 4 having an insertion opening 41. A portion of the flexible article 11 can be disposed between the first bracket 12 and the end cap 4 to provide a seal between the first bracket 12 and the end cap 4.

[0108] The aerosol generating device 100 may further include a second bracket 5. At least a portion of the second module 2 can be held in the second bracket 5 or the second module 2 can be connected to the second bracket 5. A portion of the flexible article 11 can be disposed between the first bracket 12 and the second bracket 5 to provide a seal between the first bracket 12 and the second bracket 5.

[0109] In some embodiments, reference may be made to Figure 1 , the aerosol generating device 100 further includes an air inlet hole 42 communicating with the outside. When the user sucks, the outside air can enter the interior of the aerosol generating device 100 through the air inlet hole 42, then flow into the second module 2, and enter the interior of the aerosol generating matrix section 230. The outside air can enter the interior of the aerosol generating device 100 through the air inlet hole 42, then flow into the third module 3, and enter the interior of the air guiding channel 33. Finally, it can flow into the mouthpiece 210 and be sucked into the user's mouth by the user.

[0110] The air inlet hole 42 can be one, and the second module 2 and the third module 3 can share the air inlet hole 42.

[0111] The air inlet hole 42 can be multiple. At least one air inlet hole 42 is a dedicated air inlet hole for the second module 2, and the air entering through the dedicated air inlet hole of the second module 2 mainly flows into the second module 2. At least one air inlet hole 42 is a dedicated air inlet hole for the third module 3, and the air entering through the dedicated air inlet hole of the third module 3 mainly flows into the third module 3.

[0112] In some embodiments, reference may be made to Figure 1 and Figure 6 , the end cap 4 is provided with an air inlet hole 42, and the air entering through the air inlet hole 42 can flow along the air inlet channel into the second module 2. In Figure 1 , the arrow direction indicates the air inlet direction and the flow direction of the air flow.

[0113] More specifically, there is a gap between the side wall of the end cap 4 and the first bracket 12, and this gap forms a part of the air inlet channel. The flexible article 11 located between the first bracket 12 and the second bracket 5 may have a notch 117, and the notch 117 fluidly communicates with the gap between the side wall of the end cap 4 and the first bracket 12 and the second module 2. The notch 117 can be a part of the air inlet channel.

[0114] In some embodiments, the second aerosol article includes a liquid preparation, and the second component 32 includes an atomization core configured to atomize the liquid preparation to form a second aerosol.

[0115] The atomization core may include a liquid absorption element and a heating element. The liquid absorption element is capable of adsorbing and transferring the liquid preparation and guiding the liquid preparation to the heating range of the heating element. The heating element is capable of releasing heat, so as to vaporize and atomize the liquid preparation, and then form a second aerosol. The heating element may be disposed on the liquid absorption element.

[0116] The atomization core may include an ultrasonic atomization core, which is capable of ultrasonically atomizing the liquid preparation to form a second aerosol. The atomization core may also be other atomization cores capable of generating an aerosol from the liquid preparation.

[0117] The third module 3 may also be associated with a cup body 34, and a third accommodation cavity 31 is located in the cup body 34. The air duct 35 may be integrally formed with the cup body 34. The air duct 35 may include a first portion 351 extending substantially longitudinally and a second portion 352 extending substantially transversely. The first portion 351 may be located inside the cup body 34, a part of the second portion 352 may be located inside the cup body 34 and be in fluid communication with the first portion 351, and a part of the second portion 353 may be located outside the cup body 34 and be in fluid communication with the ventilation hole 1151.

[0118] Reference may be made to Figure 7 , the second component 32 may be disposed inside the cup body 34. The third module 3 may further include a base 36 and an atomization seat 37 having an atomization cavity 371. The second component 32 may be disposed in the atomization cavity 371, and the atomization cavity 371 is in fluid communication with the air duct 33 inside the air duct 35. The base 36 connects the cup body 34 and supports the atomization seat 37, so that the atomization seat 37 is held in the cup body 34.

[0119] In some embodiments, reference may be made to Figure 3 and Figure 6 , the aerosol generating device 100 may further include a housing 6. The first module 1 can be assembled into the housing 6 from the proximal end of the housing 6. The end cap 4 and the third module 3 may be connected to form an integral structure, and then the integral structure may be assembled with the housing 6, so that the third module 3 is located in the housing 6, and the end cap 4 is connected to the proximal end of the housing 6. At the same time, the end cap 4 can abut against or block the first module 1 to prevent the first module 1 from being removed from the proximal end of the housing 6. Since the first module 1 is assembled into the housing 6 before the third module 3, for the convenience of assembling the third module 3 into the housing 6 after the first module 1 and for the convenience of realizing a sealed connection between the end of the air duct 35 and the end of the second tubular body 115, as Figure 3As shown, the inclined end of the second tubular body 115 is inclined towards the direction where the end cap 4 is located or towards the proximal end of the housing 6, so that the third module 3 can be assembled with the housing 6 longitudinally from top to bottom. When the third module 3 is assembled in place with the housing 6, the inclined end of the air guide pipe 35 can just abut against the inclined end of the second tubular body 115. Among them, from top to bottom longitudinally means in the direction from the proximal end of the housing 6 to the distal end of the housing 6 along the longitudinal direction.

[0120] It should be noted that it is optional rather than necessary for the end cap 4 and the third module 3 to be connected to form an integral structure. In other embodiments, the third module 3 and the end cap 4 can be assembled with the housing 6 one by one in a certain order.

[0121] In some embodiments, the third module 3 is configured to be removable from the housing 6, so that the third module 3 can be replaced when the second aerosol product in the third module 3 is exhausted. When the end cap 4 and the third module 3 are connected to form an integral structure, the end cap 4 and the third module 3 are detachably connected to each other. The user can operate the end cap 4 to remove the third module 3 from the housing 6, then separate the third module 3 from the end cap 4, and then replace the third module 3 alone. The end cap 4 can continue to be detachably connected to other third modules 3 to form a new integral structure, and this new integral structure can be assembled with the housing 6.

[0122] In some embodiments, the aerosol-forming substrate section 230 has a solid aerosol-forming substrate, and the first component 22 includes an internal heating element, an external heating element, and / or an air heating element.

[0123] The internal heating element refers to a heating element that is at least partially located inside the solid aerosol-forming substrate when the aerosol-generating device 100 is used in combination with the first aerosol product 200, so as to be able to heat the aerosol-forming substrate internally. For example, the internal heating element can be generally needle-shaped or sheet-shaped.

[0124] The external heating element refers to a heating element that is arranged outside the solid aerosol-forming substrate when the aerosol-generating device 100 is used in combination with the first aerosol product 200, so as to be able to heat the aerosol-forming substrate externally. For example, the external heating element can be generally tubular, capable of surrounding at least a part of the second accommodation cavity, or capable of defining at least a part of the boundary of the second accommodation cavity, so as to be able to surround at least a part of the periphery of the solid aerosol-forming substrate. Or for example, the external heating element can support the bottom or the distal end of the first aerosol product 200, so as to be able to heat the bottom of the first aerosol product 200.

[0125] The air heating element mentioned above refers to a heating element that is arranged upstream of the second accommodation cavity along the air flow direction and is used to heat the flowing air to form high-temperature air flow. Then, the high-temperature air flow flows into the second accommodation cavity 21 and enters the aerosol generation matrix, so as to heat the aerosol generation matrix with its high temperature fluid.

[0126] The heating element included in the second module 2 can have one or more, and this application does not make any restrictions.

[0127] The heating element in the second component 2 can include a resistive material, an infrared coating, and / or a susceptor.

[0128] The resistive material can generate Joule heat when an electric current flows through it. The resistive material can mainly heat the aerosol generation article through heat conduction. Suitable resistive materials include, but are not limited to: semiconductors, such as doped ceramics, conductive ceramics (such as molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic materials and metal materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include stainless steel, Constantan, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys, as well as superalloys based on nickel, iron, and cobalt, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys.

[0129] The infrared coating can radiate infrared rays when excited by heat or when an electric current passes through it. The infrared coating can mainly heat the aerosol generation matrix through thermal radiation. The infrared coating can radiate infrared rays with a wavelength of 0.75 μm to 1000 μm, preferably far infrared rays with a wavelength of 1.5 μm to 400 μm, and more preferably far infrared rays with a wavelength of 4 μm to 15 μm.

[0130] As used herein, the term "receptor" refers to a material that can convert electromagnetic energy into heat. When located in a changing electromagnetic field, the eddy currents induced in the receptor cause heating of the receptor. In such embodiments, the receptor is designed to engage with a second module that includes a magnetic field generator. The magnetic field generator generates a changing magnetic field to heat the receptor located within the changing magnetic field. In use, the receptor is located within the changing magnetic field generated by the magnetic field generator. Wherein, the magnetic field generator is electrically connected to a power supply component, and the power supply component provides a current for the magnetic field generator to generate a changing magnetic field. The magnetic field generator may include one or more induction coils that generate a changing magnetic field, and the one or more induction coils may surround the receptor. In one embodiment, the aerosol generating device is capable of generating a changing magnetic field between 1 and 30 MHz, such as between 2 and 10 MHz, such as between 5 and 7 MHz. In one embodiment, the aerosol generating device is capable of generating a changing magnetic field having a field strength (H-field) between 1 and 5 kA / m, such as between 2 and 3 kA / m, such as approximately 2.5 kA / m.

[0131] Wherein, the receptor may include metal or carbon. In one embodiment, the receptor may include a ferromagnetic material, such as ferrite, ferromagnetic steel or stainless steel. In one embodiment, the receptor includes a nickel-iron alloy. In one embodiment, the receptor includes a 400 series stainless steel, and the 400 series stainless steel includes grade 410 or grade 420 or grade 430 stainless steel.

[0132] In some embodiments, reference may be made to Figure 1 , the cross-sectional area of the first receiving cavity 112 may be larger than the cross-sectional area of the second receiving cavity 21.

[0133] Further, the second module 2 includes a first receiving tube, and the first receiving tube is used to define at least a partial boundary of the second receiving cavity 21. The inner diameter of the first receiving tube may be less than or equal to the inner diameter of the first tubular body 114. In some embodiments, the heating element 22 in the second component 2 may include the first receiving tube. The first receiving tube may include a metal tube.

[0134] In some embodiments, when the first aerosol article 200 is used in combination with the aerosol generating device 100, there is a gap between the inner wall of the first receiving tube and the first aerosol article 200, and this gap forms a part of the intake passage. External air can flow along the gap between the first receiving tube and the first aerosol article 200 to the bottom or distal end of the first aerosol article 200, and then enter the interior of the aerosol generating matrix section 230 from the bottom or distal end of the first aerosol article 200.

[0135] In some embodiments, reference may be made to Figure 1 and Figure 3, the second module 2 includes a second receiving tube 23, and the second receiving tube 23 is located between the first module 1 and the first receiving tube. At least a part of the support section 221 can be located in the second receiving tube 23. The second receiving tube 23 spaces the first module 1 from the first receiving tube. The inner wall of the second receiving tube 23 can have a guiding surface that is inclined, which helps the first aerosol article 200 to enter the first receiving tube more easily. The second receiving tube 23 can fix the first receiving tube so that the first receiving tube can be stably held inside the aerosol generating device 100. 2

[0136] In some embodiments, reference may be made to Figure 1 and Figure 3 , the second module 2 includes a base 24, and the base 24 is connected to the first receiving tube so that the first receiving tube can be stably held inside the aerosol generating device 100. The base 24 can support the bottom or the distal end of the first aerosol article 200.

[0137] In some embodiments, the aerosol generating device 100 further includes a mode selection operation unit configured to be operated by a user to select a working mode of the aerosol generating device; wherein, the working modes of the aerosol generating device 100 include a first working mode, a second working mode, and a third working mode; in the first working mode, both the second module 2 and the third module 3 are in a working state; in the second working mode, the second module 2 is in a non-working state and the third module 3 is in a working state; in the third working mode, the second module 2 is in a working state and the third module 3 is in a non-working state.

[0138] For example: The operation unit includes a button. When the user presses the button once, the aerosol generating device 100 operates in the first working mode; when the user presses the button twice in succession, the aerosol generating device 100 operates in the second working mode; when the user presses the button three times in succession, the aerosol generating device operates in the third working mode.

[0139] Or for example: The operation unit includes two buttons, namely a first button and a second button. When the user presses the first button but does not press the second button within a preset time interval, the aerosol generating device 100 operates in the second working mode; when the user presses the second button but does not press the first button within a preset time interval, the aerosol generating device 100 operates in the third working mode; when the user presses both the first button and the second button within a preset time interval, the aerosol generating device 100 operates in the first working mode.

[0140] It should be noted that in other embodiments, the operation unit can also be a knob, an operation handle, a touch screen, or a remote control device, etc.

[0141] In some embodiments, when the aerosol generating device 100 operates in the first operating mode, the user can immediately suck on the mouthpiece 210 of the first aerosol article 200 without waiting and can inhale the aerosol. Specifically, the heating of the first aerosol article 200 by the first component 22 includes a preheating stage and a sucking stage. In the preheating stage, the aerosol-forming substrate in the first aerosol article 200 is heated by the first component 22, and the temperature gradually rises from the initial temperature (the initial temperature can be room temperature) to the target temperature (the target temperature is generally higher than 200 °C). Therefore, in the preheating stage, it is difficult for the first aerosol article 200 to quickly generate the first aerosol required for the user's one puff. In some examples, the duration of the preheating stage is between 15S and 20S. In other words, the user needs to wait for 15S to 20S after the second module 2 starts working before being able to suck the first aerosol. However, since the second aerosol article includes a liquid preparation and the second component 32 includes an atomization core, the atomization core can quickly atomize the liquid preparation to generate the second aerosol when the third module 3 operates. Therefore, the user can immediately suck the second aerosol after the third module 3 starts working. Therefore, during the preheating stage after starting to operate in the first operating mode, the user can inhale an aerosol with good fullness by sucking on the mouthpiece 210 of the first aerosol article 200, and the aerosol is mainly the second aerosol.

[0142] When the first aerosol and the second aerosol have different flavors, if the aerosol generating device 100 operates in the first operating mode, the user sucking on the mouthpiece 210 of the first aerosol article 200 can obtain a changing flavor experience.

[0143] More specifically, in the first time period after starting to operate in the first operating mode, the aerosol inhaled by the user by sucking on the mouthpiece 210 is mainly the second aerosol, so the user can mainly obtain the flavor experience of the second aerosol. In the second time period, the first aerosol article 200 can generate more of the first aerosol, increasing the proportion of the first aerosol sucked into the user's mouth, but the proportion of the second aerosol is still greater than that of the first aerosol. Therefore, a flavor experience dominated by the second aerosol and supplemented by the first aerosol can be obtained. The aerosol generating device 100 can be configured such that in the third time period, the user can obtain a flavor experience in which the proportions of the first aerosol and the second aerosol are basically equal, or a flavor experience dominated by the first aerosol and supplemented by the second aerosol. Of course, it is also possible to enable the user to continue to obtain a flavor experience dominated by the second aerosol and supplemented by the first aerosol in the third stage.

[0144] After entering the suction phase of the first aerosol article 200, the aerosol-forming substrate of the first aerosol article 200 can generate a relatively large amount of the first aerosol for the user to inhale. At this time, the user can control the aerosol-generating device 100 to operate in the third operating mode to take over the operation of the first operating mode. Thus, the user can continue to inhale from the mouthpiece 210 of the first aerosol article 200 and obtain a suction experience mainly based on the first aerosol.

[0145] When the volatile substances in the aerosol-forming substrate section 230 of the first aerosol article 200 are exhausted or the remaining amount is insufficient, the user can control the aerosol-generating device 100 to operate in the second operating mode to take over the first operating mode or the third operating mode and continue to operate. Thus, the user can continue to inhale from the mouthpiece 210 of the first aerosol article 200 and obtain a suction experience mainly based on the second aerosol.

[0146] In some embodiments, reference may be made to Figure 1 and Figure 3 The aerosol-generating device 100 further includes an air flow detector 7 and a power supply assembly 8. The power supply assembly 8 includes a power supply and a circuit board electrically connected to the power supply. The second module 2 and the third module 3 are both electrically connected to the circuit board. The circuit board has a controller that can supply power to the second module 2 and the third module 3 respectively from the power supply, and further control the aerosol-generating device 100 to operate according to a preset operating mode or according to an operating mode selected by the user.

[0147] The air flow detector 7 is used for the flow rate of the air flow, the flow direction of the air flow or the air pressure, etc., to detect whether suction occurs. When it detects that suction occurs, the air flow detector 7 can control the power supply to supply power to the second module 2 and / or the third module 3, so that the aerosol-generating device 100 operates according to a preset operating mode or according to an operating mode selected by the user.

[0148] In some embodiments, the second module 2 and the third module 3 share an air inlet hole 42 for air intake, and the air flow detector 7 is arranged in the common air intake passage of the second module 2 and the third module 3, or the air flow detector 7 is in fluid communication with the second module 2 and the third module 3 at the same time. Thus, no matter what operating mode the aerosol-generating device 100 operates in, as long as the user inhales from the mouthpiece 210 of the first aerosol article 200, the air flow detector 7 can detect whether suction occurs.

[0149] In some embodiments, the second module 2 and the third module 3 intake air through independent intake holes 42, and there are two interconnected intake channels inside the aerosol generating device 100. One intake channel connects the second module 2 to one or more of the plurality of intake holes 42, and the other intake channel connects the third module 3 to another or other of the plurality of intake holes 42. The airflow detector 7 can be disposed at a position between these two airflow channels and is in fluid communication with both of them.

[0150] In some embodiments, the second module 2 and the third module 3 intake air through independent intake holes 42, and there are two independent and non-communicating intake channels inside the aerosol generating device 100. One intake channel connects the second module 2 to one or more of the plurality of intake holes 42, and the other intake channel connects the third module 3 to another or other of the plurality of intake holes 42. In one example, the airflow detector 7 is in fluid communication with the intake channel connecting to the second module 2; thus, in this example, when the aerosol generating device 100 adopts the third working mode, the intake holes 42 or the intake channel in fluid communication with the third module 3 can be closed to increase the concentration of the first aerosol flavor inhaled into the user's mouth. Of course, the intake holes 42 or the intake channel in fluid communication with the third module 3 can also be kept open when the aerosol generating device 100 adopts the third working mode. In one example, the airflow detector 7 is in fluid communication with the intake channel connecting to the third module 3; thus, in this example, when the aerosol generating device 100 adopts the third working mode, the intake holes 42 or the intake channel in fluid communication with the third module 3 need to be kept open so that the airflow detector 7 can continue to detect the suction.
