Technical Field

[0001] This application relates to the field of aerosol technology, and more particularly to an aerosol generating article and an aerosol generating system including the aerosol generating article. Background Technology

[0002] Tobacco products (e.g., cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion. An example of such a product is an aerosol generating device that releases an inhalable aerosol by heating a cigarette-shaped aerosol generating product used with it. This aerosol generating product may, for example, be tobacco or other non-tobacco products, which may or may not contain nicotine.

[0003] Existing aerosol generation devices use photothermal heating to heat the aerosol-generating product, causing it to volatilize and produce aerosols. However, the existing photothermal heating method has low heating efficiency, and the aerosol-generating product is not heated sufficiently. Utility Model Content

[0044] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" or "attached to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0045] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0046] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0047] In the embodiments of this application, "installation" includes fixing or restricting a component or device to a specific position or place by means of welding, screwing, snapping, bonding, etc. The component or device may remain stationary in the specific position or place or may move within a limited range. After the component or device is fixed or restricted to the specific position or place, it may or may not be disassembled. This application does not impose any restrictions.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. One embodiment of this application proposes a composite tobacco sheet capable of generating an aerosol by heating. In some embodiments, part or all of the composite tobacco sheet is intended to be consumed by a user during use by heating.

[0049] One embodiment of this application provides an aerosol generation system, such as Figure 1 As shown, the aerosol generation system includes an aerosol generation article 100 and an aerosol generation device 200 for heating the aerosol generation article 100 to generate aerosols. The aerosol generation device 200 is provided with a chamber 210 for containing the aerosol generation article 100. When a user needs to use the aerosol generation system for suction, the aerosol generation article 100 is inserted into the chamber 210, and then the aerosol generation device 100 is activated to heat the aerosol generation article 100. At least part of the active material filled inside the aerosol generation article 100 is evaporated by heat to generate aerosols that can be suctioned.

[0050] like Figure 2 As shown, the aerosol generating article 100 includes a housing 110 and at least one aerosol generating matrix 120 disposed within the housing 110. The aerosol generating matrix 120 is configured in a sheet-like shape to have a relatively thin thickness. For example, in some alternative embodiments, the aerosol generating matrix 120 has a thickness of approximately 0.1 mm to 2 mm. The cross-section of the aerosol generating matrix 120 can be any shape such as circular, elliptical, trapezoidal, or polygonal. The aerosol generating matrix 120 refers to a matrix capable of releasing volatile compounds that can form aerosols, which can be heated to release volatile compounds to generate aerosols.

[0051] The housing 110 has a first end 111 and a second end 112 disposed opposite to each other, both the first end 111 and the second end 112 being open, and an airflow channel 113 connecting the first end 111 and the second end 112. The aerosol released by the heated aerosol generating matrix 120 can flow into the airflow channel 113. External air enters the aerosol generating product 100 through the opening of the first end 111, and then carries the aerosol flowing into the airflow channel 113 and escapes from the opening of the second end 112. That is to say, the first end 111 serves as the air inlet for external air to enter the aerosol generating product 100, while the second end 112 serves as the air outlet for the aerosol generated after heating to escape from the aerosol generating product 100. Thus, the second end 112 can also serve as a suction end for the user to inhale the aerosol.

[0052] It should be noted that both the first end 111 and the second end 112 are open, and can be as follows: Figure 2 The first end 111 and the second end 112 shown are both open. Alternatively, in some embodiments, a vent hole can be opened on the end face of the first end 111 and the second end 112, so that external air enters into the aerosol generating article 100 through the vent hole of the first end 111, and the aerosol escapes through the vent hole of the second end 112.

[0053] In some embodiments, the aerosol generating matrix 120 may include one or more of the following: powder, granules, fragments, strips, or flakes of vanilla leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; or, the aerosol generating matrix 120 may contain additional tobacco or non-tobacco volatile flavor compounds to be released when the matrix is ​​heated.

[0054] In some embodiments, the aerosol generating matrix 120 may include an active substrate, which may include or be derived from one or more plant products or components thereof; for example, in some specific embodiments, the active substrate may include plant leaves, bark, fibrous tissue, stems, roots, petals, fruits, etc.; for example, in one specific embodiment, the active substrate may include or be derived from one or more plant varieties or their components, derivatives, or extracts, and the plant variety is tobacco. For example, in one specific embodiment, the active substrate may include a mixture of tobacco and plants such as traditional Chinese medicine. The active substrate may include tobacco or tobacco-containing materials; for example, the active substrate may include any of the following: tobacco leaves, tobacco vein fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast tobacco, and expanded tobacco.

[0055] In some optional embodiments, the aerosol generating matrix 120 further includes a flavoring agent; the flavoring agent may comprise volatile aroma components. For example, in typical embodiments, the flavoring agent may provide an aroma selected from menthol, lemon, vanilla, orange, wintergreen, cherry, and cinnamon; the flavoring agent may include volatile tobacco flavoring compounds that are released from the aerosol generating matrix 120 upon heating.

[0056] In some optional embodiments, the aerosol generating matrix 120 further includes an aerosol forming agent or a smoke generator; the aerosol forming agent or smoke generator contributes to the densification and stabilization of aerosol formation during use. In some specific embodiments, the aerosol forming agent or smoke generator is or includes at least one of glycerol, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, etc.

[0057] In some optional embodiments, the aerosol generating matrix 120 further includes an aerosol forming agent or a smoke generator; the aerosol forming agent or smoke generator contributes to the densification and stabilization of aerosol formation during use. In some specific embodiments, the aerosol forming agent or smoke generator is or includes at least one of glycerol, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, etc.

[0058] In some optional embodiments, the aerosol generating matrix 120 further includes reinforcing fibers; the reinforcing fibers typically have a higher fiber strength than the tobacco plant fibers in the active substrate, thereby enhancing the strength and plasticity of the aerosol generating matrix 120 in use. For example, in some specific embodiments, the reinforcing fibers include at least one of coniferous wood fibers, hardwood fibers, hemp or flax fibers, bamboo fibers, etc.

[0059] In some embodiments, such as Figure 3 As shown, the aerosol generating device 200 includes at least one photoheater 230, in which a heating wire 231 is provided. The aerosol generating device 200 also includes a battery cell 240 and a main board (not shown). The photoheater 230 and the battery cell 240 are both electrically connected to the main board. The main board is equipped with a controller for the aerosol generating device 200. The controller can then control the battery cell 240 to provide power to the photoheater 230. After receiving power, the heating wire 231 can generate heat and emit light.

[0060] When the aerosol generating product 100 is housed in the chamber 210, the photoheater 230 and the aerosol generating matrix 120 are opposite each other. The photoheater 230 can irradiate the aerosol generating matrix 120 to transfer heat radiation to the aerosol generating matrix 120, thereby heating the aerosol generating matrix 120. When heated to a certain temperature, some of the active substances in the aerosol generating matrix 120 will volatilize due to heat and generate aerosols.

[0061] Because the aerosol generating matrix 120 is constructed in a sheet shape and has a relatively thin thickness, and the photoheater 230 can generate high radiation energy, the aerosol generating matrix 120 can be heated to a temperature that allows aerosols to volatilize in a short time. There is no need to preheat the aerosol generating product 100. Users can start the aerosol generating device 200 to begin suction, which effectively reduces the user's waiting time and improves the user experience.

[0062] In some embodiments, the light heater 230 is a halogen lamp; or, in some embodiments, the light heater 230 is a xenon lamp.

[0063] In some embodiments, such as Figure 2 and Figure 4 As shown, the aerosol generating article 100 also includes a focusing element 130, which is arranged opposite to the aerosol generating matrix 120. When the aerosol generating article 100 is housed in the aerosol generating apparatus 200, the focusing element 130 is located between the photoheater 230 and the aerosol generating matrix 120. The focusing element 130 can be used to concentrate the light emitted by the photoheater 230 toward the aerosol generating matrix 120, so as to concentrate the light into an area that matches the volume and shape of the aerosol generating matrix 120, thereby concentrating the light emitted toward the aerosol generating matrix 120 and improving the heating efficiency of the photoheater 230.

[0064] In some embodiments, such as Figure 5 As shown, both the aerosol generating matrix 120 and the focusing element 130 include multiple components, with one focusing element 130 corresponding to one aerosol generating matrix 120. Correspondingly, the aerosol generating device 200 may also be provided with the same number of photoheaters 230 as the aerosol generating matrix 120 and the focusing element 130, so that when the aerosol generating article 100 is housed in the chamber 210, the light emitted by each photoheater 230 is focused by the corresponding focusing element 130 and then irradiates the corresponding aerosol generating matrix 120.

[0065] In some embodiments, the plurality of photoheaters 230 are arranged to be independently connected to the motherboard, and thus independently powered by the motherboard to perform heating independently. For example, in some embodiments, the plurality of photoheaters 230 are individually operable, so that each photoheater 230 can heat only the corresponding aerosol generating matrix 120.

[0066] In some embodiments, the controller is configured to control one or more photoheaters 230 to be heated sequentially, one after another, in a predetermined order. In some embodiments, the controller is configured to control one or more photoheaters 230 not to heat simultaneously; thus, for example, during user aspiration, the controller controls only one photoheater 230 to heat and generate an aerosol sufficient for one aspiration.

[0067] For example, during the user's first suction, the controller provides power to the first photoheater 230 to heat it, generating one suction of aerosol; during the user's next suction, the controller provides power to the second photoheater 230 to heat it, generating one suction of aerosol; this process continues until all photoheaters 230 are heated, and all aerosol generation matrix 120 has been suctioned, prompting the user to replace with a new aerosol generation product 100.

[0068] Alternatively, in some embodiments, the controller controls several photoheaters 230 to start sequentially and individually, without intervals along the arrangement direction of the photoheaters 230. Or, in some other variations, the controller controls several heaters 230 to start sequentially and individually, either intermittently or skipping steps.

[0069] In some embodiments, the controller controls the sequential activation of the photoheaters 230 in a cyclical manner. For example, in some embodiments, the cycle repeats a predetermined number of times; for example, 10 times. Specifically, a new cycle begins when the number of times the photoheaters 230 have been activated, and / or the number of times the user has inhaled, reaches a predetermined number, controlling the photoheaters 230 to be activated sequentially.

[0070] In some embodiments, the controller controls several photoheaters 230 to start simultaneously to increase the TPM of the aerosol (TPM is a major quality indicator for aerosols, which is the content of particulate matter in aerosols, usually measured in mg / puff, representing the amount of smoke inhaled per puff). For example, the aerosol generating device 200 can be configured to have a first mode and a second mode. The user can operate the aerosol generating device 200 to switch between the first mode and the second mode. In the first mode, the controller only controls one photoheater 230 to work, and the generated aerosol TPM is relatively small. In the second mode, the controller can control multiple photoheaters 230 to work simultaneously, thereby heating multiple aerosol generating matrices 120 at the same time, resulting in a larger aerosol TPM. The user can select the working mode of the aerosol generating device according to their needs.

[0071] In some embodiments, the number of photoheaters 230 is one, while the number of aerosol generating substrates 120 is multiple. The aerosol generating device 200 also includes a driving element (not shown) and a movable member (not shown) that is driven to the driving element. The photoheater 230 is disposed on the movable member, and the driving element is configured to drive the movable member to move so that the photoheater can sequentially irradiate and heat the aerosol generating substrates 120.

[0072] In some embodiments, the driving element may be a motor, and the transmission assembly includes a coupling fixedly connected to the rotating shaft of the electrode, and a lead screw or threaded rod connected to the coupling. The lead screw or threaded rod is connected to a movable part, and the motor can convert the rotational motion into the linear movement of the movable part through the transmission of the lead screw or threaded rod, thereby driving the photoheater 230 to move in a straight line so as to irradiate the aerosol matrix 120 in sequence.

[0073] Alternatively, in some embodiments, the transmission assembly includes a gear and a rack. The gear is connected to the output shaft of the motor, and the rack is connected to a movable part. The gear and rack mesh with each other. The rotation of the motor drives the gear to rotate synchronously. Since the gear and rack mesh with each other, the gear can drive the rack to move in a straight line, thereby causing the rack to drive the movable part to move in a straight line, which can also realize the linear movement of the light heater 230.

[0074] In some embodiments, the driving element may also be a hydraulic cylinder or a pneumatic cylinder, and the transmission connection may also be a belt drive connection or a chain drive connection.

[0075] In some embodiments, such as Figure 5 As shown, the light-concentrating element 130 is a lens. A lens is an optical element that uses the principle of refraction to manipulate light. A lens can "deflect" incident light in a planned and batch manner through its specific curved surface shape, thereby achieving the effect of light convergence.

[0076] Alternatively, in some embodiments, the light-concentrating element 130 is a reflective light-concentrating device. A reflective light-concentrating device is an optical device that uses the law of reflection to collect and focus light, unlike a lens which uses the principle of refraction. The core component of a reflective light-concentrating device is a cavity or housing with a special geometry and a highly reflective inner surface. Light is reflected multiple times inside the cavity or housing to guide or concentrate the light.

[0077] In some embodiments, such as Figure 6 As shown, the light-concentrating element 130 is a plano-convex lens, which includes a flat portion 131 and a convex portion 132. The flat portion 131 is used to allow light to enter the lens light-concentrating element 130, while the convex portion 132 is used to converge the light. By using a plano-convex lens, the flat portion of the light-concentrating element 130 can be fitted to the housing 110, thereby maintaining the appearance consistency of the aerosol-generated product 100.

[0078] In some embodiments, such as Figure 7As shown, the aerosol generating article 100 also includes a lens 140 that is bonded to the housing 110. The aerosol generating article 100 includes a plurality of plano-convex lenses 130, and the planar portion 131 of each plano-convex lens 130 is formed by the lens 140. That is, the planar portion 131 of each plano-convex lens is a part of the lens 140. In this way, when multiple plano-convex lenses 130 need to be set, it is not necessary to set multiple plano-convex lenses 130 independently. It is only necessary to set multiple convex portions on the lens 140, and the planar portion is directly formed by the lens 140. Thus, this method can maintain the appearance consistency of the aerosol generating article 100 when multiple plano-convex lenses 130 are set.

[0079] In some embodiments, the lens can be directly adhered to the outer surface of the housing 110 by an adhesive (e.g., glue), simplifying the manufacturing process.

[0080] In some embodiments, a preset gap 121 is maintained between the light-concentrating element 130 and the aerosol generating matrix 120. That is, the gap 121 needs to be within a certain range. If the gap 121 is too small, the light-concentrating element 130 and the aerosol generating matrix 120 will be too close, which may easily lead to over-baking and produce a burnt smell. If the gap 121 is too large, the light-concentrating element 130 and the aerosol generating matrix 120 will be too far apart, which will result in lower energy density and poor heating efficiency.

[0081] In some embodiments, the lens 130 is made of quartz glass, which has good light transmittance and high temperature resistance. On the one hand, it can allow as much light as possible to pass through the lens, thereby concentrating more light into a certain area, which is beneficial to improving heating efficiency. On the other hand, the high temperature resistance of quartz glass can maintain the stability of the material even when it is in a high temperature environment for a long time, avoiding a significant decrease in light transmittance.

[0082] In some embodiments, such as Figure 7 As shown, a through hole 114 is provided on the housing 110. The through hole 114 connects the outside world and the aerosol generating matrix 120. That is, the aerosol generating matrix 120 can be exposed through the through hole 114. The light-concentrating element 130 passes through the through hole 114 and extends toward the aerosol generating matrix 120 so that the light-concentrating element 130 can focus the light emitted by the light heater 230 onto the aerosol generating matrix 120, thereby heating the aerosol generating matrix 120.

[0083] In some embodiments, such as Figure 2 and Figure 8As shown, the aerosol generating article 100 also includes a support member 150 disposed within the housing 110. The support member 150 supports the aerosol generating matrix 120, thereby maintaining a first airflow gap 1151 between the aerosol generating matrix 120 and the first inner wall 115 of the housing 110. The first inner wall 115 has a through hole 114, through which light emitted by the photoheater 230 can irradiate the aerosol generating matrix 120. The light focusing member 130 in the through hole 114 can focus the light. A portion of the aerosol generated by the heating and volatilization of the aerosol generating matrix 120 can enter the first airflow gap 1151. The first airflow gap 1151 serves as part of the airflow channel 113, connecting the first end 111 and the second end 112. Figure 2 As shown by the middle arrow route R2, external air can enter the aerosol generating product 100 from the first end 111, then enter the first airflow gap 1151 and carry the aerosol released in the first airflow gap 1151 to the second end 112, and escape from the second end 112. The user can inhale the aerosol by sucking from the second end 112.

[0084] The aerosol generating matrix 120 needs to be kept in the aerosol generating article 100 in order to prevent the aerosol generating matrix 120 from shifting in the aerosol generating article 100 during storage or transportation. Once the position of the aerosol generating matrix 120 changes, the relative position of the aerosol generating matrix 120 and the focusing element 130 will also change. Consequently, the focusing element 130 will not be able to concentrate the light onto the aerosol generating matrix 120, resulting in a decrease in heating efficiency.

[0085] To retain the aerosol generating matrix 120 within the aerosol generating article 100, in some embodiments, such as Figure 8 As shown, the aerosol generating article 100 also includes a first abutment 160 and a second abutment 170 disposed within the housing 110. The first abutment 160 and the support 150 are stacked, and the second abutment 170 is stacked with the first abutment 160. The support 150, the first abutment 160 and the second abutment 170 define a mounting groove 180. When the aerosol generating matrix 120 is installed in the mounting groove 180, the support 150 and the second abutment 170 abut against the upper and lower surfaces of the aerosol generating matrix 120, respectively, thereby restricting the aerosol generating matrix 120 from axial displacement. The first abutment 160 abuts against the side of the aerosol generating matrix 120, thereby restricting the aerosol generating matrix 120 from radial displacement, thus keeping the aerosol generating matrix 120 within the aerosol generating article 100.

[0086] In some embodiments, such as Figure 2As shown, the housing 110 also includes a second inner wall 116 disposed opposite to the first inner wall 115. The aerosol generating matrix 120 maintains a second airflow gap 1161 with the second inner wall 116. The second airflow gap 1161, as part of the airflow channel 113, also connects the first end 111 and the second end 112. Figure 2 As indicated by the arrow R1, the airflow channel 113 includes a first airflow gap 1151 and a second airflow gap 1161 distributed on both sides of the aerosol generating matrix 120. When a user inhales through the second end 112, external air enters the aerosol generating product 100 from the first end 111, and then enters the first airflow gap 1151 and the second airflow gap 1161 respectively. The aerosol generated by the heating and volatilization of the aerosol generating matrix 120 can escape from both sides and enter the first airflow gap 1151 and the second airflow gap 1161 respectively. Furthermore, the external air can carry the aerosol in the first airflow gap 1151 and the second airflow gap 1161 and escape from the second end 112. In this way, the aerosol can be released more fully, improving the inhalation experience.

[0087] In some embodiments, such as Figure 2 As shown, the second airflow gap 1161 is larger than the first airflow gap 1151. Since the distance between the focusing element 130 and the aerosol generating matrix 120 cannot be too far apart, as this would result in poor heating efficiency, the distance between the aerosol generating matrix 120 and the first inner wall 115 is smaller than the distance between the second inner wall 116. In other words, the aerosol generating matrix 120 is closer to the first inner wall 115, thereby making the second airflow gap 1161 larger than the first airflow gap 1151.

[0088] In some embodiments, such as Figure 2 and Figure 7 As shown, the aerosol generating product 100 is provided with multiple aerosol generating substrates 120. These substrates 120 are arranged sequentially and at intervals along the extension direction of the airflow channel 113, thus constructing the aerosol generating product 100 as a long strip shape. Alternatively, the multiple aerosol generating substrates 120 can be described as being arranged sequentially and at intervals along the length of the aerosol generating product 100. By constructing the aerosol generating product 100 in a long strip shape, after the aerosol generating product 100 is inserted into the aerosol generating device 200, its second end 112 is exposed, allowing the user to directly perform suction at the second end 112.

[0089] Alternatively, in some embodiments, such as Figure 9 and Figure 10As shown, the aerosol generating article 100 can also be constructed in a generally square shape, in which case the aerosol generating matrix 120 can be arranged in an array within the aerosol generating article 110. For example... Figure 10 As shown, the aerosol generating product 100 contains six aerosol generating substrates 120, which can be arranged in two columns, with three aerosol generating substrates in each column. Because this type of aerosol generating product 100 is relatively short, its second end 112 is not exposed after being placed in the aerosol generating device 200, therefore the user cannot directly perform suction on the second end 112.

[0090] like Figure 9 As shown, to accommodate this type of aerosol-generating product 100, the aerosol generating device 200 is equipped with a suction nozzle 220, which defines an outlet 221 for aerosol to escape. The opening of the chamber 210 is located on the side of the aerosol generating device 200 so that the user can place the aerosol-generating product 100 into the chamber 210. The photoheater 230 is located at the bottom of the chamber 210. When the aerosol-generating product 100 is placed into the chamber 210, each photoheater 230 corresponds to the corresponding aerosol-generating substrate 120, and the light emitted by each photoheater 230 can be focused onto the aerosol-generating substrate 120 by the corresponding focusing element 230 to heat the aerosol-generating substrate 120.

[0091] The mouthpiece 220 is connected to the chamber 210. When the user inhales through the mouthpiece 220, outside air enters the chamber 210 and then enters the aerosol generating product 100 from the first end 111. It carries the released aerosol out from the second end 112 into the chamber 210 and finally flows into the mouthpiece 220 for the user to inhale.

[0092] And, in some embodiments, such as Figure 9 As shown, the aerosol generating device 200 also includes a cover 240 for shielding the chamber 210. When the user does not need the aerosol generating device 200, the cover 240 can be rotated to the first position to shield the chamber 210, preventing dust and other particulate matter in the air from falling into the chamber 210 and contaminating the photoheater 240. When the user needs to use the aerosol generating device 200, the cover can be rotated to the second position to expose the chamber 210, and the user can then place the aerosol generated product 100 into the chamber 210.
