Description

Technical Field

[0001] The present disclosure relates to a heated (HNB) aerosol generating device and a capsule configured to generate an aerosol without substantially thermally decomposing an aerosol generating substance.

Background Art

[0002] Some electronic devices are configured to avoid substantial thermal decomposition of plant material by heating the plant material to a temperature sufficient to release its components while maintaining the temperature below the combustion point of the plant material. Such devices may be referred to as aerosol generating devices (e.g., heated aerosol generating devices), and the heated plant material may be tobacco and / or cannabis. In some examples, the plant material may be introduced directly into the heating chamber of the aerosol generating device. In other examples, the plant material may be pre-packaged in individual containers to facilitate insertion into or removal from the aerosol generating device.

[0075] Several detailed exemplary embodiments are disclosed herein. However, the specific structural and functional details disclosed herein are provided solely for the purpose of describing the exemplary embodiments. However, the exemplary embodiments may be carried out in many different forms and should not be construed as being limited only to the exemplary embodiments described herein.

[0076] Accordingly, the exemplary embodiments are subject to various modifications and other forms, which are shown in the drawings and described in detail herein. However, the exemplary embodiments are not intended to be limited to the specific forms disclosed, but rather encompass all modifications, equivalents, and other forms that fall within the scope of the exemplary embodiments. Throughout the description with respect to the drawings, similar reference numerals indicate similar elements.

[0077] When one component or layer is described as "on top of," "connected to," "linked to," or "covering" another component or layer, that component or layer may be directly on top of, connected to, linked to, or cover the other component or layer, or there may be an intervening component or layer. Conversely, when one component is described as "directly on top of," "directly connected to," or "directly linked to" another component or layer, there is no intervening component or layer. Throughout the specification, similar reference numerals indicate similar components. In this specification, the word "and / or" includes any one or more and all combinations of the items listed with this word.

[0078] In this specification, terms such as first, second, third, etc., are used to describe various members, regions, layers, and / or parts, but it should be understood that these members, regions, layers, and / or parts are not limited to these terms. These terms are used merely to distinguish one member, region, layer, or part from another. Accordingly, the first member, component, region, layer, or part described below may also be described as a second member, region, layer, or part without departing from the teachings of the exemplary embodiments.

[0079] In this specification, terms describing spatial relationships (e.g., “below,” “below,” “bottom,” “above,” “top,” etc.) are used for convenience to describe the illustrated relationship between one member or feature and another member or feature. It should be understood that these terms describing spatial relationships are intended to include various orientations of the device in use or operation, in addition to the orientation shown in the drawings. For example, if the device in the drawing is inverted, a member described as being “below” or “below” another member or feature would be “above” that other member or feature. Therefore, the term “below” can include both upward and downward orientations. The device may have other orientations (90-degree rotation or other orientations), and the terms describing spatial relationships used herein may be interpreted accordingly.

[0080] The terminology used in this specification is for the purpose of describing various exemplary embodiments and is not intended to limit them. The singular forms "a," "an," and "the" used herein are intended to include plural cases unless explicitly stated otherwise. Furthermore, it should be understood that the words "include," "include," "equip," and / or "equip" specify the presence of the features, integers, processes, operations, and / or components described herein, and do not exclude the presence or addition of one or more other features, integers, processes, operations, components, and / or groups thereof.

[0081] In this specification, when the terms “approximately” or “substantially” are used in relation to numerical values, these values ​​are intended to include manufacturing or operational tolerances (e.g., ±10%) from the stated numerical value. Furthermore, when the terms “generally” or “substantially” are used in relation to geometric shapes, precision of the geometric shape is not required, and shapes including tolerances are intended to be within the scope of this disclosure. Moreover, whether or not numerical values ​​or shapes are modified with the terms “approximately,” “generally,” or “substantially,” these numerical values ​​and shapes should be understood to include manufacturing or operational tolerances (e.g., ±10%) from the stated numerical value or shape.

[0082] All terms used herein (including technical and scientific terms) have the same meaning as those commonly understood by those skilled in the art in the field to which the exemplary embodiments belong, unless otherwise specified. Furthermore, these terms, including those defined in commonly used dictionaries, should be interpreted as having meanings consistent with their respective field meanings, and should not be interpreted in an idealized or overly formal sense unless explicitly specified otherwise herein.

[0083] In this specification, “to connect” includes both removable and permanent connections. For example, when an elastic layer and a support layer are removablely connected to each other, the elastic layer and the support layer may separate when sufficient force is applied.

[0084] Figures 1 to 10 show an aerosol generating device 100 (e.g., a heated non-breathable (HNB) aerosol generating device) according to at least one exemplary embodiment. For example, Figure 1 is a perspective view of the aerosol generating device 100 from above, showing the lid 110 in a closed state. Figure 2 is a perspective view of the aerosol generating device 100 from below, showing the lid 110 in a closed state. Figure 3 is a view of the aerosol generating device 100 from below, showing the lid 110 in a closed state. Figure 4 is a view of the aerosol generating device 100 from above, showing the lid 110 in a closed state. Figure 5 is another perspective view of the aerosol generating device 100 from above, showing the lid 110 in an open state. Figure 6 is another perspective view of the aerosol generating device 100 from above, showing the lid 110 in an open state. Figure 7 is a view of the aerosol generating device 100 from above, looking downwards, showing the lid 110 in the open position. Figure 8 is another perspective view of the aerosol generating device 100 from above, showing the lid 110 open and the capsule 200 being received in the capsule receiving cavity 130. Figure 9 is a cross-sectional view of the aerosol generating device 100, showing the lid 110 open and the capsule 200 being received in the capsule receiving cavity 130. Figure 10 is a partial perspective view of the aerosol generating device 100, showing a portion of the housing 120 removed to reveal various internal components, with the lid 110 open and the capsule 200 being received in the capsule receiving cavity 130.

[0085] As illustrated, in at least some exemplary embodiments, the aerosol generating device 100 generally has an elliptical or pebble-like shape and includes a replaceable mouthpiece 190 extending from the body of the aerosol generating device 100. For example, the aerosol generating device 100 may include a housing 120 defining a capsule receiving cavity 130 (best shown in Figures 5 to 8). Furthermore, a lid 110 is configured to open and close relative to the housing 120 and is connectable to the replaceable mouthpiece 190. For example, the lid 110 may be fixedly connected to the housing 120 at a first point 122, or it may be openably connected to the housing 120 at a second point 124. The first point 122 of the housing 120 may be on the first side 102 of the device 100. The second point 124 of the housing 120 may be on the second side 104 of the aerosol generating device 100. In some examples, the lid 110 may also be called a door. The external shape of the housing 120 and / or lid 110 may be formed from metal (e.g., aluminum, stainless steel, etc.), plastics that are aesthetically pleasing and have a food-contact rating (e.g., polycarbonate (PC), acrylonitrile butadiene styrene (ABS), liquid crystal polymer (LCP), copolyester plastic, or other suitable polymers and / or plastics), or a combination thereof. Similarly, the replaceable mouthpiece 190 may be formed from metal (e.g., aluminum, stainless steel, etc.), plastics that are aesthetically pleasing and have a food-contact rating (e.g., polycarbonate (PC), acrylonitrile butadiene styrene (ABS), liquid crystal polymer (LCP), copolyester plastic, or other suitable polymers and / or plastics), and / or plant-based materials (e.g., wood, bamboo, etc.). One or more internal surfaces or the housing 120 and / or lid 110 may be formed from high-temperature plastics (e.g., polyetheretherketone (PEEK), liquid crystal polymer (LCP), etc.) or coated with them. The lid 110 and the housing 120 can be considered together as the main body of the aerosol generating device 100.

[0086] The lid 110 may be fixedly connected to the housing 120 at a first point 122 by a hinge 112 or a similar connector. This allows the lid 110 to move (e.g., by swinging and rotating) from an open position (e.g., shown in Figures 5 to 10) to a closed position (e.g., shown in Figures 1 and 2). As shown in Figure 10, the hinge 112 may include a torsion spring 117. In at least some exemplary embodiments, as shown in Figures 5, 6 and 8 to 10, the housing 120 includes a recess 126 at the first point 122. The recess 126 may be configured to receive a portion of the lid 110, thereby allowing the lid 110 to move easily and smoothly from an open position to a closed position (or vice versa). The recess 126 may have a structure corresponding to the relevant portion of the lid 110. For example, as shown, the recess 126 may include a substantially curved portion 127. The lid 110 is generally convex in shape, and the substantially curved portion 127 corresponds to the curvature of the lid 110.

[0087] The lid 110 may be releasably connected to the housing 120 at a second point 124 by a latch 114 or a similar connector. This allows the lid 110 to be fixed or stably mounted in a closed position and to be easily released and moved from the fixed closed position to the open position. In at least one exemplary embodiment, the latch 114 may be connected to a latch release mechanism 116. The latch release mechanism 116 may be configured to move the latch 114 from a first position or closed position to a second position or open position. For example, as best shown in Figure 10, the latch 114 may extend downward within the housing 120, and the latch release mechanism 116 may be perpendicular to the downward-extending portion of the latch 114. Thus, the latch release mechanism 116 is configured to apply pressure to the latch 114. For example, the latch release mechanism 116 may be movable between a first position and a second position. In the first position, the latch release mechanism 116 may be neutral with respect to the latch 114. In the second position, the latch release mechanism 116 can move the latch 114 from a fixed or latched position to an open position by applying pressure to the downward-extending portion of the latch 114.

[0088] In at least one exemplary embodiment, as best shown in Figure 10, the latch release mechanism 116 communicates with a latch release button 118, which is configured to activate the latch release mechanism 116, i.e., to move the latch 114 from a first position or closed or fixed position to a second position or pressurized position, and further to move / return the latch 114 from the open position to the fixed or closed position. In at least one exemplary embodiment, the latch release button 118 is a button located on the second side 104 of the aerosol generating device 100 that interacts with an adult consumer. For example, when an adult consumer presses the latch release button 118, the latch release mechanism 116 may move the latch 114 from the fixed or closed position to the open position by moving from the first position or closed or fixed position to a second position or pressurized position. The latch release button 118 may have a substantially circular shape with a central recess or indentation configured to determine the direction of pressure applied by an adult consumer, but exemplary embodiments are not limited thereto. One or more sensors (not shown) configured to detect when the lid 110 is open and closed may be embedded in or otherwise provided within one or more components of the housing 120 and / or inside it (e.g., the latch 114, the latch release mechanism 116, the latch release button 118).

[0089] In at least some exemplary embodiments, as best shown in Figures 9 and 10, the housing 120 houses or accommodates a power supply 150 and a processing or control circuit 160, in addition to the latch release mechanism 116. The control circuit 160 may be hardware including logic circuits, a hardware / software combination such as a processor that runs software, or a combination thereof. For example, the processing circuit 160 may include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field-programmable gate array (FPGA), a system-on-a-chip (SoC), a programmable logic unit, a microprocessor, an application-specific integrated circuit (ASIC), and the like. The current supply from the power supply 150 may be responsive to manual operation (e.g., activation by a button) or to automatic operation (e.g., puff-activated). The power supply 150 may include one or more batteries (e.g., a rechargeable dual battery structure, a lithium-ion battery, and / or a fuel cell). In at least some exemplary embodiments, the control circuit 160 may further include a haptic motor which may be located on the side of the power supply 150.

[0090] In at least some exemplary embodiments, as best shown in Figures 1, 2, 5, and 8 through 10, the housing 120 includes a consumer interface panel 143 located on the second side 104 of the device 100. For example, the consumer interface panel 143 may be an egg-shaped panel extending along the second side of the device 100. In addition to the latch release button 118 as described above, the consumer interface panel 143 may include a communication screen 140 and / or a power button 142. For example, in at least some exemplary embodiments, the consumer interface panel 143 may include a communication screen 140 located between the latch release button 118 and the power button 142. As shown, the latch release button 118 may be located on the top of the aerosol generating device 100, and the power button 142 may be located on the bottom of the aerosol generating device 100. Like the latch release button 118, the power button 142 may also be a button that interacts with adult consumers. The power button 142 may have a substantially circular shape with a central recess or indentation configured to determine the direction of pressure applied by an adult consumer, but the exemplary embodiments are not limited thereto. The power button 142 can turn the aerosol generating device 100 on and off. Although only two buttons are shown, it should be understood that more or fewer buttons may be provided depending on the available features and the desired interface with the adult consumer.

[0091] In at least one exemplary embodiment, the communication screen 140 is an integrated thin-film transistor ("TFT") screen. In other exemplary embodiments, the communication screen 140 is an organic light-emitting diode ("OLED") or light-emitting diode ("LED") screen. The communication screen 140 is configured to engage with adult consumers and may generally have an oval shape.

[0092] In at least some exemplary embodiments, the housing 120 defines a charging connector or port 170. For example, as best shown in Figure 2, the charging connector 170 may be defined and / or provided at the lower end of the housing 120 distal to the capsule receiving cavity 130. The charging connector 170 may be configured to charge the power supply 150 inside the aerosol generating device 100 by receiving current from an external power source (e.g., via a USB / mini USB cable). For example, in at least one exemplary embodiment, as best shown in Figure 3, the charging connector 170 may be an assembly defining a cavity 171 and having a projection 175 within the cavity 171. In some exemplary embodiments, the projection 175 does not extend beyond the edge of the cavity 171. Furthermore, the charging connector 170 may be configured to send and receive data with other aerosol generating devices (e.g., heated non-breathable (HNB) aerosol generating devices) and / or electronic devices (e.g., telephones, tablets, computers, etc.) (e.g., via a USB / mini USB cable). In at least one embodiment, the aerosol generating device 100 may be configured, in addition to or instead, to wirelessly communicate with the other aerosol generating devices and / or electronic devices described above (e.g., via Bluetooth).

[0093] In at least some exemplary embodiments, a protective grille 172 is provided around the charging connector 170, as best shown in Figure 3. The protective grille 172 may be configured to help reduce / prevent the ingress of debris and / or unintentional blocking of incoming airflow. For example, the protective grille 172 may define a plurality of pores 173 along the longitudinal direction or course. As shown, the protective grille 172 may have an annular shape surrounding the charging connector 170. In this regard, the pores 173 may also be arranged around the charging connector 170 (e.g., in series). Each of the pores 173 may, but is not limited to, have an oval or circular shape. In at least one exemplary embodiment, the protective grille 172 may include an approved food-contact material. For example, the protective grille 172 may include plastic, metal (e.g., stainless steel, aluminum), or a combination thereof. In at least some exemplary embodiments, the surface of the protective grille 172 may be coated with, for example, a thin film of plastic, or anodized.

[0094] The pores 173 within the protective grille 172 can function as inlets for air drawn into the aerosol generating device 100. During operation of the aerosol generating device 100, ambient air entering through the pores 173 in the protective grille 172 around the charging connector 170 forms a flow aggregate by convergence, which then moves to the capsule 200. For example, the pores 173 can be in fluid communication with the capsule receiving cavity 130. In at least some exemplary embodiments, air can be drawn from the pores 173 through the capsule receiving cavity 130. For example, air can be drawn through the capsule 200 received by the capsule receiving cavity 130 and exit through the replaceable mouthpiece 190.

[0095] The capsule 200 (for example, shown in Figure 8) can have various forms and configurations. For example, the capsule 200 may have any of the forms and configurations described later with reference to Figures 32 to 46. Specifically, in one exemplary embodiment, the capsule 200 may be the same as that described with respect to the capsule 1300 in Figures 37 to 41. As shown in Figures 37 to 41, the capsule 1300 includes a housing configured to contain an aerosol-generating material (for example, the aerosol-generating material 1860' shown in Figure 48) and a heater, the downstream portion of the housing may be in the form of a first end cap 1310 (for example, a downstream cap). The upstream portion of the housing may be in the form of a second end cap 1320 (for example, an upstream cap, a connector cap). The main body of the housing may be in the form of a cover 1330 (for example, a shell, a box sleeve).

[0096] As shown in Figures 37 to 38, the first end cap 1310 defines the first opening 1312, and the second end cap 1320 defines the second opening 1322. In one exemplary embodiment, the first opening 1312 is in the form of a series of outflow openings (e.g., nine outflow openings), and the second opening 1322 is in the form of a series of inflow openings (e.g., eight inflow openings). Furthermore, the second end cap 1320 may expose the first end 1342 and the second end 1346 of the heater 1340 (e.g., Figure 41). As shown, the second opening 1322 may be between the exposed portion of the first end 1342 and the exposed portion of the second end 1346. The first end cap 1310 and / or the second end cap 1320 are transparent and can act as windows configured to allow the contents / components inside the capsule 1300 (e.g., aerosol-generating material and / or heater) to be visible.

[0097] As shown in Figure 39, the middle section 1344 of the heater 1340 is an internal segment configured to heat the aerosol-generating material in the capsule 1300. The first end 1342 and the second end 1346 of the heater 1340 are external segments configured to establish an electrical connection with a power source (e.g., an electrical connection with power source 150 via electrical contacts 152a and 152b).

[0098] The second end cap 1320 defines, in addition to the second opening 1322, an alignment recess 1326 and an inlet recess 1328. The alignment recess 1326 and the inlet recess 1328 can be considered as multi-level structures. The base / internal end face of the alignment recess 1326 (exposing the first end 1342 and the second end 1346) can be considered as one level, and the base / internal end face of the inlet recess 1328 (or the grille-like surface of the second opening 1322) can be considered as another level. The alignment recess 1326 is configured to facilitate the positioning of the capsule 1300 when inserting it into the device body of the aerosol generating device. In one exemplary embodiment, the alignment recess 1326 has an angled side wall that tapers inward as it approaches the inlet recess 1328. Because the alignment recess 1326 has an angled side wall, it can be very easily and quickly coupled to the corresponding engaging member of the device body. For example, when received in the capsule receiving cavity 130 of the aerosol generating device 100, the alignment recess 1326 of the capsule 1300 may engage with the angled surface 176 of the capsule connector 132, and the inlet recess 1328 of the capsule 1300 may engage with the capsule seal 202 (e.g., Figure 12). As a result, the capsule 1300 can be properly loaded into the body of the aerosol generating device and positioned in a relatively consistent manner.

[0099] As shown in Figure 40, the first end cap 1310 includes a first sealing ridge 1314, and the second end cap 1320 includes a second sealing ridge 1324. In one exemplary embodiment, the first sealing ridge 1314 is in the form of a series of ribs (e.g., four ribs), and the second sealing ridge 1324 is in the form of a series of ribs (e.g., four ribs). In some examples, the individual ribs in each arrangement may have different heights to ensure desirable contact with the cover 1330. When the capsule 1300 is assembled, the first sealing ridge 1314 of the first end cap 1310 and the second sealing ridge 1324 of the second end cap 1320 are configured to provide an airtight seal by interfaceing with the inner surface of the cover 1330 (e.g., via interference fits). As a result, when air is directed towards capsule 1300 during the operation of the aerosol generating device, the air enters capsule 1300 through the inlet recess 1328 and second opening 1322 in the second end cap 1320 (and not through the gap between the second end cap 1320 and cover 1330, in which case the air could essentially simply flow along the inner surface of cover 1330, bypassing the aerosol-generating material and / or intermediate portion 1344 of heater 1340). Similarly, provided a proper airtight seal is provided, the aerosol generated in the chamber of capsule 1300 is drawn out through the first opening 1312 in the first end cap 1310 (and not leaks out through the gap between the first end cap 1310 and cover 1330).

[0100] As shown in Figure 41, the heater 1340 includes a first end 1342, an intermediate section 1344, and a second end 1346. The intermediate section 1344 of the heater 1340 may have a planar and winding shape resembling compression vibration or a zigzag, having a plurality of mutually parallel segments (e.g., 8 to 16 mutually parallel segments). However, it should be understood that the intermediate section 1344 of the heater 1340 may also have other shapes (e.g., a helical shape, a floral shape). The endpoints of the first end 1342 and the second end 1346 may be oriented perpendicular to the plane of the intermediate section 1344. Each of the first end 1342 and the second end 1346 may further have a segment having a J-shaped side surface. As a result, the first end 1342 and the second end 1346 can be embedded relatively stably within the second end cap 1320 while providing a pair of electrical contact surfaces.

[0101] It should be understood that the above description is intended to introduce, without limitation, capsule 200, which may be identical to capsule 1300 as described above. Therefore, inserting capsule 200 into the aerosol generating device 100 and engaging it mechanically / electrically can be described in relation to the specific details of capsule 1300. Further details and variations of capsule 1300 are also described below.

[0102] In at least one exemplary embodiment, as best shown in Figure 10, the housing 120 houses or accommodates an air hose 180. The air hose 180 may extend between the capsule receiving cavity 130 and one or more air inlets or holes 173, and / or may be physically connected to them (via an air inlet connection 184). An air channel assembly 181 may be provided as an intermediary between the air hose 180 and the holes 173. In such an example, the air channel assembly 181 may be configured to direct the incoming airflow (drawn in through the holes 173) toward the air hose 180. In at least one exemplary embodiment, the air channel assembly 181 includes an airflow regulator configured to optimally control the airflow via a device 100. In at least one exemplary embodiment, one or more flow sensors 185 may be located within or along the air channel assembly 181 and / or along the air hose 180. In at least one exemplary embodiment, one or more flow sensors 185 include microelectrochemical system (MEMS) flow sensors, pressure sensors, or other types of sensors configured to measure airflow, such as hot-wire anemometers. In at least one exemplary embodiment, one or more flow sensors 185 may include pressure sensors, such as capacitive pressure sensors, configured to measure negative pressure during suction events. In at least one exemplary embodiment, the air channel assembly 181 may not include one or more sensors 185.

[0103] In at least some exemplary embodiments, the housing 120 surrounds the capsule connector 132. In some further examples, the capsule connector 132 is mounted on or otherwise secured to a printed circuit board (PCB) within the housing 120. In at least one exemplary embodiment, the capsule connector 132 defines a capsule receiving cavity 130. Figures 11 to 15 show the capsule connector 132 according to at least one exemplary embodiment.

[0104] In at least some exemplary embodiments, the capsule connector 132 includes a body or housing 134 defining a capsule receiving cavity 130. In at least some exemplary embodiments, as best shown in Figure 13, the body 134 includes an air inlet connection 184. The air inlet connection 184 may be configured to connect to the end of an air hose 180. In at least some exemplary embodiments, the body 134 includes one or more couplers or mounting brackets 135, 136 configured to connect the capsule connector 132 to the housing 120 and / or components within the housing 120. The first coupler or mounting bracket 136 may include, for example, one or more wing or tab portions 137 and a coupler receiving opening 138 (e.g., mounting bosses). The coupler receiving opening 138 may be configured to receive one or more corresponding couplers of the housing 120 (e.g., coupler 128 (e.g., screw) shown in Figure 15). The second coupler or mounting bracket 135 may include, for example, one or more wing or tab portions 141 and a coupler receiving opening 139. The coupler receiving opening 139 may be configured to receive one or more corresponding couplers of the lid 110. For example, the coupler receiving opening 139 may be configured to receive a post 115 defined on the inner surface of the lid 110. Specifically, a switch (e.g., a push-button switch) may be positioned within the coupler receiving opening 139 so that the switch is pressed by the post 115 when the lid 110 is closed and released when the lid 110 is opened. As a result, a method for detecting the opening and closing of the lid may be provided.

[0105] In at least some exemplary embodiments, the capsule connector 132 includes one or more electrical connectors or contacts 152A, 152B. For example, as shown, the capsule connector 132 may include a first electrical contact 152A and a second electrical contact 152B. As shown, the first electrical contact 152A may be in the form of three contact members. Similarly, the second electrical contact 152B may also be in the form of three contact members. The electrical contacts 152A, 152B are configured to apply current or other electrical signals to the capsule 200 received by the capsule receiving cavity 130. In at least one exemplary embodiment, the electrical contacts 152A, 152B may electrically communicate with a power supply 150 and / or control circuit 160 provided within the housing 120. The electrical contacts 152A, 152B may be formed of copper or a copper alloy (e.g., copper-titanium), but there is also the option of having gold plating.

[0106] As best shown in Figure 14, in at least some exemplary embodiments, each of the contact members of the electrical contacts 152A and 152B can be of two types, namely contact member 152' or contact member 152''. For example, electrical contact 152A may include a combination of contact member 152' and contact member 152''. As shown, electrical contact 152A may include contact member 152'' between a pair of contact members 152'. In another example, electrical contact 152A may include contact member 152' between a pair of contact members 152''. Alternatively, electrical contact 152A may include multiple contact members of either contact member 152' or contact member 152'' (e.g., the same contact member) rather than two types of contact members.

[0107] Similarly, the electrical contact 152B may include a combination of both contact members 152' and contact members 152''. As shown in the figure, the electrical contact 152B may include a contact member 152'' between a pair of contact members 152'. In another example, the electrical contact 152B may include a contact member 152' between a pair of contact members 152''. Alternatively, the electrical contact 152B may include multiple contact members 152' and 152'' (for example, the same contact member) rather than two types of contact members.

[0108] Each of the contact members 152' and 152” includes a base 154A, 154B, respectively. In at least one exemplary embodiment, each of the contact members 152' and 152” includes a terminal or solder point 162A, 162B, respectively. As shown, the solder point 162A of the contact member 152' may be aligned with the base 154A (e.g., coaxially). Conversely, the solder point 162B of the contact member 152” may be offset laterally from the base 154B, so as not to be aligned with the base 154B, but extending parallel to the base 154B. As a result, the contact members 152' and 152” may be arranged alternately, and consequently, the solder points 162A, 162B may be arranged in a zigzag pattern in the electrical contacts 152A, 152B (e.g., Figures 13 and 14). In one exemplary embodiment, solder points 162A and 162B are configured to engage with corresponding apertures on a printed circuit board within the housing 120. As a result, the solder points 162A and 162B can establish mechanical and electrical connections between contact members 152' and 152'' (forming electrical contacts 152A and 152B) and a power supply 150 and / or control circuit 160 located within the housing 120.

[0109] In at least one exemplary embodiment, each of the contact members 152', 152” (of the electrical contacts 152A, 152B) includes continuous spring features 156A, 156B extending from bases 154A, 154B, respectively. The continuous spring features 156A, 156B may have a planar and convex form. The continuous spring features 156A, 156B are movable between a first compressed position and a second extended position (for example, in a direction orthogonal to each base 154A, 154B).

[0110] In at least one exemplary embodiment, each of the contact members 152', 152” (of the electrical contacts 152A, 152B) includes a contact pin or contact surface 158A, 158B extending from the continuous spring features 156A, 156B, respectively. For example, the contact surfaces 158A, 158B extend from the continuous spring features 156A, 156B at their distal ends from the bases 154A, 154B. The contact surfaces 158A, 158B may extend from the continuous spring features 156A, 156B into the capsule receiving cavity 130, thereby allowing the contact surfaces 158A, 158B to contact the internal capsule 200 (for example, via the ends of the capsule 200, similar to the first end 1342 and the second end 1346 of the capsule 1300).

[0111] In this way, the contact surfaces 158A and 158B are spring-loaded, thereby improving their engagement with the capsule 200. For example, the contact surfaces 158A and 158B may extend into the capsule receiving cavity 130 by a first amount when in use, and by a second amount when not in use. The first amount is smaller than the second amount. For example, the contact surfaces 158A and 158B may extend into the capsule receiving cavity 130 by approximately 0.20 mm (i.e., the first amount) when in use, because the continuous spring features 156A and 156B are compressed or loaded. On the other hand, when not in use, the contact surfaces 158A and 158B may extend into the capsule receiving cavity 130 by approximately 0.90 mm (i.e., the second amount) because the continuous spring features 156A and 156B are not compressed or loaded. Thus, in at least one exemplary embodiment, the electrical contacts 152A and 152B are configured such that a connection with the capsule 200 is not established until the capsule 200 is fully inserted into the capsule receiving cavity 130.

[0112] In at least some exemplary embodiments, as best shown in Figure 11, each of the electrical contacts 152A and 152B may be formed by a combination of both contact members 152' and contact member 152” (e.g., Figure 14). For example, the electrical contact 152A may include a contact member 152” between a pair of contact members 152'. Similarly, the electrical contact 152B may include a contact member 152'' between a pair of contact members 152'. Although the electrical contacts 152A and 152B are shown as including three contact members, it should be understood that exemplary embodiments are not limited thereto. Specifically, in other examples, the electrical contacts 152A and 152B may include more (e.g., four contact members each) or fewer (e.g., one to two contact members each) contact members than the three shown. Since the contact members 152' and 152'' of the electrical contacts 152A and 152B are separate structures configured to allow independent mechanical / electrical engagement with one another, an improved electrical connection can be established between the electrical contacts 152A and 152B and the capsule 200 (via the ends of the capsule 200, similar to the first ends 1342 and 1346 of the capsule 1300). It should be noted that the fact that the electrical contacts 152A and 152B are separate structures may provide a more reliable and flexible connection to the power supply 150 and / or the control circuit 160.

[0113] In at least some exemplary embodiments, the control / heating method and associated circuits and electrical contacts (e.g., one or more electrical connectors or capsule connector 132 including contacts 152A, 152B) are described in U.S. Patent Application No. __ / ______, filed concurrently with this application, titled "Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Energy-Based Heater Control, And Methods Of Controlling A Heater" (Agent Reference Number 24000NV-000668-US), and U.S. Patent Application No. __ / ______, filed concurrently with this application, titled "Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Intra-Draw Heater Control, And Methods Of Controlling A This may be described in "Heater" (heated (HNB) aerosol generator including heater control during suction, and method for controlling the heater) (Agent reference number 24000NV-000670-US). The entirety of each of the above applications is incorporated herein by reference.

[0114] The capsule 200 is first loaded into the aerosol generating device 100 by inserting it into the capsule receiving cavity 130 defined by the capsule connector 132. In at least some exemplary embodiments, the capsule 200 makes contact (e.g., full contact) with the electrical contacts 152A, 152B within the capsule receiving cavity 130 only when a force (e.g., a downward / inward force) is applied to the capsule 200. In at least one exemplary embodiment, the force is applied to the capsule 200 by closing and / or latching the lid 110. In another exemplary embodiment, the force is applied to the capsule 200 by an adult consumer. In yet another exemplary embodiment, the force is applied to the capsule 200 by a combination of pressure applied by an adult consumer and closing and / or latching the lid 110. In each example, the force is applied until resistance is felt and / or a click is heard. The resistance or click indicates that the capsule 200 has fully engaged with the capsule receiving cavity 130.

[0115] The underside of the lid 110 may include an impact / engagement member or surface 113 configured to engage with the capsule 200 when the lid 110 rotates to the closed position. The impact / engagement member or surface 113 of the lid 110 may include a recess (e.g., corresponding to the size and shape of the capsule 200) and / or elastic material, thereby improving the interface with the capsule 200 and providing the desired sealing condition. When the capsule 200 is inserted into the capsule receiving cavity 130, the weight of the capsule 200 itself may not be sufficient to compress the electrical contacts 152A, 152B (e.g., to compress them at least to a significant degree). As a result, the capsule 200 may simply rest on the exposed pins of the electrical contacts 152A and 152B (e.g., the contact surfaces 158A and 158B of the contact members 152' / 152") without compressing (or significantly compressing) the electrical contacts 152A and 152B. Furthermore, when the lid 110 rotates to the closed position, the weight of the lid 110 itself may not compress the electrical contacts 152A and 152B to a significant degree, and the lid 110 may simply rest on the capsule 200 in a partially open position. In such an example, by performing an intentional action to close the lid 110 (e.g., a downward force), the impact / engagement member or surface 113 of the lid 110 may be affected. The force required to close the lid 110 pushes down the capsule 200, providing the desired seal, and further compresses the electrical contacts 152A and 152B, thereby engaging them. Furthermore, when the lid 110 is fully closed, it engages with the latch 114, thereby maintaining the closed position and the desired mechanical / electrical engagement, including the capsule 200, until the latch 114 is released (e.g., via the latch release button 118). The force required to close the lid 110 may help to ensure and / or improve the airtight / aerosol seal. Furthermore, the force may help to provide a stronger electrical connection and, in addition, may help to improve the device, thermal efficiency, and battery life by reducing / eliminating the initial power draw to the capsule 200 and / or the heating of parasites to the capsule 200.

[0116] In at least some exemplary embodiments, as best shown in Figure 11, the capsule receiving cavity 130 includes a first portion or upper end 166A and a second portion or lower end 166D distal to the first end 166A. For example, contact surfaces 158A, 158B may extend through the second end 166D of the capsule receiving cavity 130. When the lid 110 is in the closed position, the first end 166A may communicate with the lid 110 and / or the replaceable mass piece 190. In at least some exemplary embodiments, the first end 166A has a first width and the second end 166D has a second width. The first width may be greater than the second width. For example, in at least one exemplary embodiment, the first cross-sectional dimensions of the capsule receiving cavity 130 at the first end 166A may be 7.2 mm × 13.6 mm, and the second cross-sectional dimensions of the capsule receiving cavity 130 at the second end 166D may be 6.2 mm × 12.6 mm. In this case, the cross-sectional dimensions of the capsule 200 are 6.0 mm × 12.4 mm. Thus, in at least one exemplary embodiment, the capsule receiving cavity 130 may be tapered (e.g., the width / lateral dimension decreases by 5-15%) between the first end 166A and the second end 166D, thereby configuring the capsule receiving cavity 130 to position the capsule 200 appropriately. In addition to potentially improving moldability, the tapered configuration may provide a thin layer of air around the capsule 200 (e.g., thermal insulation) during use of the device 200.

[0117] In at least some exemplary embodiments, the lower end 166D of the capsule receiving cavity 130 includes a capsule seal 202, as best shown in Figures 12 and 15. When the capsule 200 is housed within the capsule receiving cavity 130, the capsule seal 202 is configured to mate with an input recess of the capsule 200 (e.g., an inlet recess of the capsule 200, similar to the inlet recess 1328 of the capsule 1300). The capsule seal 202 may be configured to help ensure and / or improve the airtight / aerosol-sealed state between the capsule 200 and the capsule connector 132, thereby directing all (or substantially all) of the air received through the air inlet connection 184 towards the capsule 200. In at least one exemplary embodiment, the capsule seal 202 may be a silicone seal.

[0118] In at least some exemplary embodiments, the lower end 166D of the capsule receiving cavity 130 includes one or more alignment members configured to help ensure correct alignment between the capsule 200 and the electrical contacts 152A, 152B. In at least one exemplary embodiment, as best shown in Figures 12 and 13, the one or more alignment members may include one or more flat surfaces 174 and / or one or more angled surfaces 176. One or more flat surfaces 174 may provide a hard stop for the capsule 200, and the electrical contacts 152A, 152B may extend through one or more flat surfaces 174. As shown, a pair of flat surfaces 174 may be provided, and the capsule seal 202 is positioned between the flat surfaces 174. One or more angled surfaces 176 may include one or more 15-degree draft surfaces (e.g., 0.05 mm smaller than the uniform profile of the capsule 200) extending downward from one or more flat surfaces 174 to a surrounding depth portion 177. The depth portion 177 is the deepest part or bottom of the capsule receiving cavity 130. In one exemplary embodiment, the alignment member may resemble a pair of plateaus, i.e., where angled surfaces 176 (e.g., ramps) rise from the surrounding depth portion 177 and reach a flat surface 174. In some further examples, three angled surfaces 176 may connect to the corresponding flat surface 174.

[0119] The distal / upstream end of the capsule 200 may have a shape corresponding to one or more alignment members formed within the capsule receiving cavity 130. As a result, the capsule 200 can be properly positioned in a relatively simple and consistent manner when loaded into the aerosol generating device 100. When the capsule 200 is inserted into the capsule receiving cavity 130, the ends of the capsule 200 (which may be similar to the first end 1342 and the second end 1346 of the capsule 1300) can first rest on the electrical contacts 152A, 152B. A downward / inward force on the capsule 200 (e.g., by closing the lid 110) biases the capsule 200 downward / inward, thereby compressing the electrical contacts 152A, 152B (e.g., via the spring features 156A, 156B of the contact members 152', 152"), thereby retracting into the capsule connector 132. As a result, the ends of the capsule 200 (which may be analogous to the first end 1342 and second end 1346 of the capsule 1300) are pressed against the electrical contacts 152A, 152B while aligning within the capsule receiving cavity 130. It may also contact the flat surface 174 of the material. Furthermore, the alignment recess of the capsule 200 (which may be similar to the alignment recess 1326 of the capsule 1300) may contact or be adjacent to the angled surface 176 of the alignment member in the capsule receiving cavity 130. Furthermore, the inlet recess of the capsule 200 (which may be similar to the inlet recess 1328 of the capsule 1300) may receive the capsule seal 202 by elastic engagement. In such examples, a relatively close fit with the capsule 200 can be established, and as a result, a stable electrical connection with the capsule 200 and a desired sealing state can be established.

[0120] Figures 16 to 20 show the replaceable mouthpiece 190. In at least some exemplary embodiments, the replaceable mouthpiece 190 includes a first end 192 and a second end 194 distal to the first end 192. In at least one exemplary embodiment, the replaceable mouthpiece 190 may be tapered between the first end 192 and the second end 194. For example, the diameter or average length / width dimension of the first end 192 may be smaller than the diameter or average length / width dimension of the second end 194. The tapered portion may have a curved portion 191 that curves slightly inward as it approaches the first end 192. The curved portion 191 is configured to accommodate the lips of an adult consumer and to improve comfort and experience.

[0121] The first end 192 may have an oval or elliptical shape and may include one or more outlets 196. For example, as shown, the first end 192 may include four outlets 196, so that four or more different areas or four or more quadrant areas of an adult consumer's mouth can be engaged during use of the aerosol generating device 100.

[0122] The second end 194 may be connectable to the lid 110. For example, in at least one exemplary embodiment, the second end 194 includes a projection 197, one or more ridges 195, and one or more connecting structures 198. The projection 197 may include a recess 193, and in at least some exemplary embodiments, one or more ridges 195 may extend from the recess 193 in a direction perpendicular (or substantially perpendicular). In another exemplary embodiment, one or more ridges 195 may extend from the main surface of the projection 197 in a direction perpendicular (or substantially perpendicular). The projection 197 and the one or more ridges 195 may be configured to position or adjust the replaceable mouthpiece 190 relative to the lid 110. One or more connecting structures 198 may be configured to connect the replaceable mouthpiece 190 to the lid 110. One or more connecting structures 198 may be a bubble coupler or a protruding coupler. For example, as shown in the figure, the interchangeable mouthpiece 190 may include four bubble couplers or protruding couplers, which are arranged in pairs along the main longitudinal direction of the second end 194 of the interchangeable mouthpiece 190.

[0123] In at least some exemplary embodiments, the replaceable mouthpiece 190 can be inserted through an opening 111 in the lid 110 configured to receive and secure the second end 194 of the replaceable mouthpiece 190 (by a snap-fit ​​structure). Thus, as best shown in Figures 1, 6, and 9, the projection 197, one or more ridges 195, and one or more connecting structures 198 are covered by the lid 110 when assembled with the aerosol generating device 100. For example, once the aerosol generating device 100 is assembled, only the tapered portion and the first end 192 of the replaceable mouthpiece 190 may be visible. The presence of further fitting features (e.g., connecting structures 198) may provide confirmation feedback (e.g., an audible click) when the replaceable mouthpiece 190 is properly engaged with the lid 110.

[0124] Figures 21 to 26 show an aerosol generating device 500 (e.g., a heated non-breathable (HNB) aerosol generating device) according to at least one exemplary embodiment. The aerosol generating device 500 is the same as the aerosol generating device 100 except that it includes a cylindrical mouthpiece 590. For example, Figure 21 is a perspective view of the aerosol generating device 500 from above, showing the lid 110 in the closed position. Figure 22 is a perspective view of the aerosol generating device 500 from below, showing the lid 110 in the closed position. Figure 23 is a view of the aerosol generating device 500 from above looking downwards, showing the lid 110 in the closed position. Figure 24 is another perspective view of the aerosol generating device 500 from above looking downwards, showing the lid 110 in the open position. Figure 25 is a top view of the aerosol generating device 500, showing the lid 110 in the open position. Figure 26 is another perspective view of the aerosol generating device 500 from above, showing the lid 110 open and the capsule 200 being received in the capsule receiving cavity 130.

[0125] Figures 27 to 31 show the interchangeable mouthpiece 590. In at least some exemplary embodiments, the interchangeable mouthpiece 590 includes a first end 592 and a second end 594 distal to the first end 592. Unlike the interchangeable mouthpiece 190, the first end 592 of the interchangeable mouthpiece 590 may have a substantially cylindrical shape. Although only two shapes are described, those skilled in the art will recognize that the first ends 192, 592 of the interchangeable mouthpieces 190 and 590 can take on various configurations. The second end 594 of the interchangeable mouthpiece 590 may have the same or similar shape as the second end 194 of the interchangeable mouthpiece 190, so that the interchangeable mouthpiece 590 can similarly engage with the opening 111 of the lid 110.

[0126] For example, in at least one exemplary embodiment, the replaceable mouthpiece 590 may be tapered between a first end 592 and a second end 594. For example, the diameter of the first end 592 may be smaller than the diameter or average length / width dimension of the second end 594. The tapered portion may have a curved portion 591 that curves slightly inward as it approaches the first end 592. The curved portion 591 is configured to accommodate the lips of an adult consumer and to improve comfort and experience.

[0127] The first end 592 of the replaceable mouthpiece 590 includes one or more outlets 596. For example, as shown, the first end 592 may include four outlets 596 (e.g., outwardly spreading outlets) so that four or more different areas or four or more quadrant areas of an adult consumer's mouth can be engaged during use of the aerosol generating device 500.

[0128] The second end 594 may be connectable to the lid 110. For example, in at least one exemplary embodiment, the second end 594 includes a projection 597, one or more ridges 595, and one or more connecting structures 598. The projection 597 may include a recess 593, and in at least some exemplary embodiments, one or more ridges 595 may extend from the recess 593 in a direction perpendicular (or substantially perpendicular). In another exemplary embodiment, one or more ridges 595 may extend from the main surface of the projection 597 in a direction perpendicular (or substantially perpendicular). The projection 597 and the one or more ridges 595 may be configured to position or adjust the replaceable mouthpiece 590 relative to the lid 110. One or more connecting structures 598 may be configured to connect the replaceable mouthpiece 590 to the lid 110. One or more connecting structures 598 may be a bubble coupler or a protruding coupler. For example, as shown in the figure, the interchangeable mouthpiece 590 may include four bubble couplers or protruding couplers, which are arranged in pairs along the main longitudinal direction of the second end 594 of the interchangeable mouthpiece 590.

[0129] In at least some exemplary embodiments, an aerosol generating device according to at least some exemplary embodiments (e.g., aerosol generating device 100 shown in Figures 1 to 10 and / or aerosol generating device 500 shown in Figures 21 to 26) is configured to receive a capsule (e.g., capsule 200) containing an aerosol generating substance (e.g., aerosol generating substance 1860'). Further details and / or variations of the aerosol generating devices, capsules, and / or aerosol generating materials are provided in U.S. Patent Application No. __ / ______, filed concurrently with this application, titled "Capsules Including Embedded Heaters And Heat-Not-Burn (HNB) Aerosol-Generating Devices" (Agent Reference Number 24000NV-000667-US), U.S. Patent Application No. __ / ______, filed concurrently with this application, titled "Aerosol-Generating Capsules" (Agent Reference Number 24000NV-000716-US), and U.S. Patent Application No. __ / ______, filed concurrently with this application, titled "Heat-Not-Burn (HNB) Aerosol-Generating Devices And This can be seen in "Capsules" (heat-activated (HNB) aerosol generating capsules and capsules) (Agent reference number 24000NV-000718-US). The entirety of each of the above applications is incorporated herein by reference.

[0130] As described above, an aerosol-generating substance is a material or combination of such materials capable of producing an aerosol. An aerosol is a substance generated or produced by the devices and their equivalents disclosed herein and described in the claims. Such materials may contain compounds (e.g., nicotine, cannabinoids), and when the material is heated, an aerosol containing this compound is produced. The heating may be below the combustion temperature, thereby producing the aerosol without causing substantial thermal decomposition of the aerosol-generating substance or substantial generation of combustion byproducts (if any). Thus, in some exemplary embodiments, no thermal decomposition occurs during heating and the production of the aerosol therefrom. In other examples, some thermal decomposition and combustion byproducts may occur, but to a relatively small extent and / or may be considered merely incidental.

[0131] The aerosol-producing substance may be a fibrous material. The fibrous material may be, for example, a plant material. The fibrous material is configured to release a compound when heated. The compound may be a natural component of the fibrous material. The fibrous material may be, for example, a plant material such as tobacco, and the released compound may be nicotine. The term “tobacco” includes any tobacco plant material, which includes tobacco leaves, tobacco plugs, reconstituted tobacco, compressed tobacco, shaped tobacco, or powdered tobacco obtained from one or more species of the tobacco plant, e.g., Nicotiana rustica and Nicotiana tabacum, and combinations thereof.

[0132] In some exemplary embodiments, the tobacco material may include material obtained from any member of the genus Nicotiana. Furthermore, the tobacco material may include a blend of two or more different tobacco species. Examples of suitable types of tobacco material that can be used include, but are not limited to, yellow tobacco, barley tobacco, dark tobacco, Maryland tobacco, Oriental tobacco, rare tobacco, specialty tobacco, and blends thereof. The tobacco material may be provided in any suitable form, which includes, but is not limited to, tobacco layers, processed tobacco material (e.g., increased volume tobacco or puffed tobacco), processed tobacco stems (e.g., cut and rolled stems or cut and puffed stems), reconstituted tobacco material, and blends thereof. In some exemplary embodiments, the tobacco material is substantially in the form of a mass of dry tobacco. In further exemplary embodiments, the tobacco material may be mixed with and / or combined with at least one of propylene glycol, glycerin, subcombinations thereof, or combinations thereof.

[0133] The compounds may also be natural components of medicinal plants that possess medically acceptable therapeutic effects. For example, the medicinal plant could be a cannabis plant, and the compounds could be cannabinoids. Cannabinoids interact with receptors in the body to produce a wide range of effects. As a result, cannabinoids have been used for various medical purposes (e.g., pain, nausea, epilepsy, and mental illness). The fibrous material may include leaf and / or flower material obtained from one or more species of cannabis plants (e.g., Cannabis sativa, Cannabis indica, and Cannabis ruderalis). In some examples, the fibrous material is a mixture containing 60-80% (e.g., 70%) of Cannabis sativa and 20-40% (e.g., 30%) of Cannabis indica.

[0134] Examples of cannabinoids include tetrahydrocannabinol (THCA), tetrahydrocannabinol (THC), cannabidiolic acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC), and cannabigerol (CBG). Tetrahydrocannabinol (THCA) is a precursor of tetrahydrocannabinol (THC), and cannabidiolic acid (CBDA) is a precursor of cannabidiol (CBD). Tetrahydrocannabinol (THCA) and cannabidiolic acid (CBDA) can be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, by heating. In one exemplary embodiment, heat from a heater may cause decarboxylation, thereby converting tetrahydrocannabinol (THCA) in the capsule to tetrahydrocannabinol (THC) and / or cannabidiolic acid (CBDA) in the capsule to cannabidiol (CBD).

[0135] In cases where both tetrahydrocannabinol (THCA) and tetrahydrocannabinol (THC) are present in a capsule, decarboxylation and the resulting conversions reduce tetrahydrocannabinol (THCA) and increase tetrahydrocannabinol (THC). During heating of the capsule, at least 50% (e.g., at least 87%) of tetrahydrocannabinol (THCA) may be converted to tetrahydrocannabinol (THC). Similarly, in cases where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in a capsule, decarboxylation and the resulting conversions reduce cannabidiolic acid (CBDA) and increase cannabidiol (CBD). During heating of the capsule, at least 50% (e.g., at least 87%) of cannabidiolic acid (CBDA) may be converted to cannabidiol (CBD).

[0136] Furthermore, the compound may be a non-natural additive, or may contain even more non-natural additives, which are then introduced into the fibrous material. In one example, the fibrous material may contain at least one of the following: cotton, polyethylene, polyester, rayon, or combinations thereof (e.g., in the form of gauze). In another example, the fibrous material may contain a natural material such as a cellulose material (e.g., a non-tobacco material and / or a non-cannabis material). In either example, the compound introduced may include nicotine, cannabinoids, and / or flavoring agents. The flavoring agents may be from natural sources such as plant extracts (e.g., tobacco extract, cannabis extract) and / or from artificial sources. In yet another example, when the fibrous material contains tobacco and / or cannabis, the compound may contain one or more flavoring agents (e.g., menthol, mint, vanilla), or even more. Thus, the compound in the aerosol-producing substance may contain natural components and / or non-natural additives. In this regard, it should be understood that the level of natural components in the aerosol-producing substance can be increased by supplementation. For example, the level of nicotine in a given amount of tobacco can be increased by supplementing with a nicotine-containing extract. Similarly, the level of one or more cannabinoids in a given amount of cannabis can be increased by supplementing with a cannabinoid-containing extract.

[0137] In at least some exemplary embodiments, the aerosol generating device according to at least some exemplary embodiments (e.g., the aerosol generating device 100 shown in Figures 1 to 10 and / or the aerosol generating device 500 shown in Figures 21 to 26) is configured to generate an aerosol by heating a capsule (e.g., capsule 200). In one exemplary embodiment, the method of generating an aerosol may first include loading the capsule 200 into the aerosol generating device 100 or the aerosol generating device 500. To load the capsule 200, the lid 110 is rotated to the open position and the capsule 200 is inserted into the capsule receiving cavity 130 defined by the capsule connector 132. The lid 110 is then rotated to the closed position to engage the lid 110 with the latch 114, and the lid 110 remains in the closed position while the capsule 200 is further pushed into the capsule receiving cavity 130 so that the capsule 200 is fully seated.

[0138] When the capsule 200 is fully seated within the capsule receiving cavity 130, the ends of the capsule 200 (which may be analogous to the first ends 1342 and 1346 of the capsule 1300) are pressed against the electrical contacts 152A, 152B (for example, against the exposed tips of the contact surfaces 158A, 158B of the contact members 152', 152"), and as a result, are compressed and retracted via the spring features 156A, 156B of the contact members 152', 152". While the ends of the capsule 200 (which may be analogous to the first ends 1342 and 1346 of the capsule 1300) are pressed against the electrical contacts 152A, 152B, they may also be in contact with the flat surface 174 of the alignment member within the capsule receiving cavity 130. Furthermore, the alignment recess of the capsule 200 (which may be similar to the alignment recess 1326 of the capsule 1300) may contact or be adjacent to the angled surface 176 of the alignment member in the capsule receiving cavity 130. In addition, the inlet recess of the capsule 200 (which may be similar to the inlet recess 1328 of the capsule 1300) may receive the capsule seal 202 by elastic engagement. As a result, a relatively stable electrical connection with the capsule 200 and the desired sealing state can be established.

[0139] The aerosol generating device 100 or the aerosol generating device 500 can be activated using the consumer interface panel 143 (for example, by pressing the power button 142) and / or by detection of an inhalation event (for example, using the flow sensor 185). After activation, the control circuit 160 is configured to instruct the power button 150 to supply current to the capsule 200 via electrical contacts 152A, 152B in the capsule receiving cavity 130. Specifically, the capsule 200 includes a heater (which may be analogous to the heater 1340 of the capsule 1300). The heater is configured to resistively heat in response to current from the power supply 150 introduced via its ends (which may be analogous to the first end 1342 and the second end 1346 of the capsule 1300). As a result of resistive heating, the temperature of the aerosol-generating material in the capsule 200 rises, thereby releasing volatile substances and generating an aerosol.

[0140] In at least one exemplary embodiment, the heating of the aerosol-producing material within the capsule 200 may be below the combustion temperature of the aerosol-producing material, thereby producing the aerosol without causing substantial thermal decomposition of the aerosol-producing material or substantial generation of combustion byproducts (if any). Thus, in one exemplary embodiment, no thermal decomposition occurs during heating and the resulting aerosol production. In other examples, some thermal decomposition and combustion byproducts may occur, but to a relatively small extent and / or may be considered merely incidental. Methods of heating / control may be described in U.S. Patent Application No. __ / ______, titled “Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Energy Based Heater Control, And Methods Of Controlling A Heater” (Agent Reference Number 24000NV-000668-US), filed concurrently with this application, and U.S. Patent Application No. __ / ______, titled “Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Intra-Draw Heater Control, And Methods Of Controlling A Heater” (Agent Reference Number 24000NV-000670-US), filed concurrently with this application. The entire disclosures of each of the above applications are incorporated herein by reference.

[0141] Once suction or negative pressure is applied to the aerosol generating device 100 (e.g., via the mouthpiece 190) or to the aerosol generating device 500 (e.g., via the mouthpiece 590), ambient air is drawn into the aerosol generating device 100 or 500 through the pores 173 in the grille 172. Once inside, the airflow from the pores 173 converges and passes through the air channel assembly 181, and can then be directed towards the air hose 180. The converged airflow can be detected / monitored as appropriate by the flow sensor 185 in the air channel assembly 181 and / or air hose 180. The airflow is then directed from the air hose 180 towards the air inlet connection 184 of the capsule connector 132. The airflow then passes through the capsule seal 202 and enters the inlet opening in the capsule 200 (which may be similar to the opening 1322 of the capsule 1300). Inside capsule 200, air can flow through the aerosol-generating material and along the surface of the heater (e.g., longitudinally), thereby pulling in volatile substances released by the aerosol-generating material. As a result, an aerosol is generated. Finally, the resulting aerosol passes through an outlet opening in capsule 200 (which may be similar to the opening 1312 of capsule 1300) and then exits aerosol generating device 100 (e.g., via the outlet 196 of mouthpiece 190) or aerosol generating device 500 (e.g., via the outlet 596 of mouthpiece 590).

[0142] In at least some exemplary embodiments, a method of use relating to the aerosol generating device 100 or the aerosol generating device 500 may include securing a replaceable mouthpiece (e.g., replaceable mouthpiece 190 and / or replaceable mouthpiece 590) to a lid (e.g., 110). For example, the method may include inserting the replaceable mouthpiece into an opening in the lid (e.g., opening 111) until resistance is felt and / or a click is heard, while the lid is in the open position. In at least some exemplary embodiments, a method of use may include replacing a replaceable mouthpiece (e.g., replaceable mouthpiece 190 and / or replaceable mouthpiece 590). Replacing a replaceable mouthpiece may include opening the lid (e.g., 110), removing the first replaceable mouthpiece from the opening (e.g., opening 111), and inserting the second replaceable mouthpiece into the opening until resistance is felt and / or a click is heard.

[0143] While capsule 200 has been presented as one embodiment in relation to aerosol generating devices 100 and 500, it should be understood that other suitable embodiments are also possible. Further details, modifications, and variations of the capsule are described below with reference to Figures 32 to 46.

[0144] Figure 32 is a downstream perspective view of a capsule for an aerosol generating device according to an exemplary embodiment. Figure 33 is an upstream perspective view of the capsule of Figure 32. As shown in Figures 32 and 33, the capsule 1200 may include a housing having a downstream portion, an upstream portion, and a body portion between the downstream and upstream portions. The downstream portion of the housing may be in the form of a first end cap 1210 (e.g., a downstream cap). The upstream portion of the housing may be in the form of a second end cap 1220 (e.g., an upstream cap). The body portion of the housing may be in the form of a cover 1230 (e.g., a shell, a box sleeve).

[0145] The first end cap 1210 defines the first opening 1212, and the second end cap 1220 defines the second opening 1222. In one exemplary embodiment, the first opening 1212 is in the form of a series of outflow openings (e.g., five outflow openings), and the second opening 1222 is in the form of a series of inflow openings (e.g., five inflow openings). In another example, the openings may be arranged in a matrix rather than in series. Furthermore, the second end cap 1220 may expose the first end 1242 and the second end 1246 of the heater 1240 (e.g., Figure 34). As shown, the second opening 1222 may be between the exposed portion of the first end 1242 and the exposed portion of the second end 1246. The first end cap 1210 and the second end cap 1220 may be formed from high-temperature plastic. Examples of suitable high-temperature plastics, not limited to the present invention, include liquid crystal polymers (LCPs), polyetheretherketones (PEEKs), or cyclic olefin copolymers (COCs). Furthermore, the first end cap 1210 and the second end cap 1220 may be the same color or different colors (e.g., transparent). In examples where the first end cap 1210 and / or the second end cap 1220 are transparent, they may act as windows configured to allow visibility of the contents / components within the capsule 1200 (e.g., aerosol-generating material and / or heater). The colors of the first end cap 1210 and the second end cap 1220 may, as appropriate, be used to identify stock-keeping units (SKUs).

[0146] The cover 1230 may be formed from metal / alloy, high-temperature plastic, and / or plant material. In some examples, the metal may include aluminum and the alloy may be stainless steel. The high-temperature plastic may be the same as those disclosed in relation to the first end cap 1210 and the second end cap 1220. The plant material may include cellulose fiber (e.g., in the form of paper pulp). In terms of dimensions, the cover 1230 may have a thickness (e.g., wall thickness) of about 0.4 mm to 0.6 mm (e.g., 0.5 mm), but exemplary embodiments are not limited thereto. In addition to being formed entirely from one of the above materials, the cover 1230 may have a composite / multilayer structure. For example, the cover 1230 may include a combination of a metal lower / inner layer and an upper / outer layer made of plastic and / or plant material (e.g., paper, cardboard).

[0147] If metal / alloy is used to manufacture cover 1230, the manufacturing process may include extruding the metal / alloy to form cover 1230. In another example, the manufacturing process may include forming cover 1230 by pressing / drawing (e.g., punching a sheet of metal / alloy into the desired shape) and cutting. In yet another example, the manufacturing process may include stamping a sheet of metal / alloy to the desired size / shape, folding it to form cover 1230, and then, as appropriate, seam welding and / or labeling. The latter two processes may reduce manufacturing costs.

[0148] The capsule 1200 may have a rectangular parallelepiped shape including a front surface, a rear surface opposite the front surface, a first side surface between the front and rear surfaces, a second side surface opposite the first side surface, a downstream end surface, and an upstream end surface opposite the downstream end surface. It should be understood that a capsule receiving cavity (e.g., the capsule receiving cavity 130 of the aerosol generating device 100) may be configured to accommodate such a shape in order to receive the capsule 1200. Although the capsule 1200 has been shown having a rectangular parallelepiped shape (e.g., a rectangular parallelepiped other than a cube with rounded corners), it should be understood that exemplary embodiments are not limited thereto. For example, in some examples, the shape that the capsule 1200 may have may have an external view or cross section that resembles a rectangle (e.g., elongated circle, oval, capsule tablet shape, stadium shape, racetrack shape), oval / egg shape, or ellipse) with a pair of opposite semicircular ends. The chamber defined within the capsule 1200 may have the same shape as the outer shape of the capsule 1200, or it may have a different shape. For example, both the cross-section of the chamber and the outer shape of the capsule 1200 may be rectangular. In another example, the cross-section of the chamber may be something other than rectangular (e.g., oval) and the cross-section of the outer shape of the capsule 1200 may be rectangular (and vice versa).

[0149] Figure 34 is an exploded view of the capsule of Figure 32. Figure 35 is an exploded perspective view of the capsule of Figure 32 viewed from the upstream side. As shown in Figures 34 and 35, the first end cap 1210 includes a protruding edge or flange around its periphery. The degree of protrusion of the protruding edge of the first end cap 1210 may be approximately the same as the wall thickness of the cover 1230. Similarly, the second end cap 1220 includes a protruding edge or flange around its periphery. The degree of protrusion of the protruding edge of the second end cap 1220 may be approximately the same as the wall thickness of the cover 1230. The first end cap 1210 and the second end cap 1220 are configured to engage with the inner surface of the cover 1230. The protruding edges of the first end cap 1210 and the second end cap 1220 may act as stoppers when the first end cap 1210 and the second end cap 1220 engage with the cover 1230. Furthermore, once the capsule 1200 is assembled, the edges of the first end cap 1210 and the second end cap 1220 can be substantially flush with the surface of the adjacent cover 1230.

[0150] In another embodiment, the first end cap 1210 may be integrated with the cover 1230 to form a single structure. For example, the manufacturing process may include pressing / drawing a metal sheet so that the first end cap 1210 and the cover 1230 are integrally formed from the same material (e.g., as a continuous shell). The first opening 1212 may be pre-punched in the metal sheet before pressing / drawing or punched in the metal sheet after pressing / drawing.

[0151] The heater 1240 includes a first end 1242, an intermediate section 1244, and a second end 1246. The first end 1242 and the second end 1246 include an external segment of the heater 1240 configured to establish an electrical connection with a power source (e.g., receiving current from power source 150). During manufacturing, the heater 1240 may be embedded in the second end cap 1220 by injection molding (e.g., insert molding, overmolding). The intermediate section 1244 is an internal segment of the heater 1240 configured to heat an aerosol-generating material (e.g., aerosol-generating material 1860 in Figure 47). When the capsule 1200 is assembled, the intermediate section 1244 of the heater 1240 may be aligned between the first opening 1212 and the second opening 1222.

[0152] The aerosol-generating material for capsule 1200 may be in an integrated or loose state. Specifically, if the aerosol-generating material is in an integrated state, it may have a shape that facilitates its placement within the housing. For example, the aerosol-generating material may be in the form of one or more rectangular sheets / slabs adjusted to dimensions such that they are inserted into the cover 1230. If the aerosol-generating material is loose, it may be loaded into the cover 1230 by a vacuum-assisted process. In such a process, the housing may first be partially assembled so that the second end cap 1220 engages with the cover 1230 (with the heater 1240 embedded). Then, by applying a vacuum to the second opening 1222 of the second end cap 1220, the nearby aerosol-generating material may be drawn into the open end of the cover 1230. The degree of vacuum may be adjusted as appropriate to achieve the desired density of the aerosol-generating material for capsule 1200. In this way, multiple capsules can be loaded simultaneously and relatively consistently.

[0153] Figure 36 is an enlarged view of the heater in Figure 34. To manufacture the heater 1240, the sheet material may be cut or processed in other ways (e.g., punching, electrochemical etching, die cutting, laser cutting). In such examples, the heater 1240 has an integrated continuous form. The sheet material may be formed of one or more conductors configured to be Joule heated (also known as ohm heating / resistance heating). Suitable conductors for the sheet material include iron alloys (e.g., stainless steel, iron aluminide), nickel alloys (e.g., nichrome), and / or ceramics (e.g., metal-coated ceramics). For example, the stainless steel may be of the type known in the art as SS316L, but exemplary embodiments are not limited thereto. The sheet material may have a thickness of about 0.10 to 0.30 mm (e.g., 0.15 mm to 0.25 mm). The heater 1240 may have a resistance value of about 0.5 ohms to 2.5 ohms (e.g., 1.0 ohm to 2.0 ohms). As shown in Figure 36, the heater 1240 has a first end 1242, an intermediate section 1244, and a second end 1246. The first end 1242 and the second end 1246 are configured to be electrically connected to a power source when the capsule 1200 is loaded into the device body of the aerosol generating device. When the heater 1240 is activated (e.g., by Joule heating), the temperature of the aerosol generating material may rise, causing an aerosol to be generated and drawn in or released through the first opening 1212 of the capsule 1200, and then flow downstream and exit through the mouthpiece (e.g., the replaceable mouthpiece 190).

[0154] The intermediate section 1244 of the heater 1240 may have a planar and winding shape resembling compression vibration or a zigzag, having a plurality of parallel segments (e.g., 8 to 16 parallel segments). Each of the parallel segments may have a width of about 0.28 mm to 0.32 mm (e.g., 0.30 mm), and the spacing between the parallel segments may be about 0.30 mm to 0.34 mm (e.g., 0.32 mm), but other dimensions are also possible. In one exemplary embodiment, the intermediate section 1244 can more completely heat the chamber in the cover 1230 by occupying a rectangular area. However, it should be understood that the intermediate section 1244 of the heater 1240 may also have other forms (e.g., spiral shape, floral shape). Furthermore, the endpoints of the first end 1242 and the second end 1246 may be oriented perpendicular to the plane of the intermediate section 1244. Furthermore, each of the first end 1242 and the second end 1246 may have a segment with a J-shaped side surface. This segment facilitates the transition from the plane of the intermediate portion 1244 to the plane of the electrical contact surfaces of the first end 1242 and the second end 1246 that is perpendicular to the plane of the intermediate portion 1244. In this respect, the first end 1242 and the second end 1246 can also be thought of as resembling a pair of "feet" of the heater 1240. As a result, the first end 1242 and the second end 1246 can be embedded relatively stably within the second end cap 1220 while providing a pair of electrical contact surfaces (for example, to engage with the electrical contacts 152a and 152b of the aerosol generating device 100).

[0155] Figure 37 is a downstream perspective view of another capsule for an aerosol generating device according to an exemplary embodiment. Figure 38 is an upstream end view of the capsule of Figure 37. In general, capsule 1300 has commonalities (e.g., features, properties, constituent materials, manufacturing method) with capsules 200 and 1200. Therefore, unless otherwise specified, it should be understood that capsule 1300 may have aspects similar to those disclosed with respect to capsules 200 and 1200. As shown in Figures 37 and 38, capsule 1300 has a housing configured to contain an aerosol generating material (e.g., aerosol generating material 1860' in Figure 48) and a heater, the downstream portion of the housing may be in the form of a first end cap 1310 (e.g., downstream cap). The upstream portion of the housing may be in the form of a second end cap 1320 (e.g., upstream cap, connector cap). The main body of the housing may be in the form of a cover 1330 (e.g., shell, box sleeve).

[0156] The first end cap 1310 defines the first opening 1312, and the second end cap 1320 defines the second opening 1322. In one exemplary embodiment, the first opening 1312 is in the form of a series of outflow openings (e.g., nine outflow openings), and the second opening 1322 is in the form of a series of inflow openings (e.g., eight inflow openings). In another example, the openings may be arranged in a matrix rather than in series. Furthermore, each opening having a width of approximately 0.26 mm to 0.30 mm (e.g., 0.28 mm) can reduce or prevent particles of aerosol-generating material from escaping. Rectangular recesses are shown on both sides of the first end cap 1310 and the second end cap 1320, but it should be understood that these features (e.g., gating features) are a result of the manufacturing process (e.g., injection molding) and may be omitted in some embodiments. Furthermore, the second end cap 1320 may expose the first end 1342 and the second end 1346 of the heater 1340 (for example, Figure 41). As shown, the second opening 1322 may be located between the exposed portion of the first end 1342 and the exposed portion of the second end 1346.

[0157] As illustrated, the shape of the capsule 1300 may be such that its outer view or cross-section resembles a rectangle with a pair of opposing semicircular ends (e.g., elongated circle, oval, capsule tablet shape, stadium shape, racetrack shape). The shape of the capsule 1300 may also be conceivable as a cylinder that has been elongated radially or flattened along its longitudinal axis. However, it should be understood that the capsule 1300 may also have other suitable shapes. For example, in some examples, the capsule 1300 may have an egg-shaped or ellipsoidal shape with an egg-shaped or elliptical cross-section. In another example, the capsule 1300 may have a rectangular parallelepiped with a rectangular cross-section (e.g., a rectangular parallelepiped other than a cube with rounded corners). The chamber defined within the capsule 1300 may have the same shape as the outer shape of the capsule 1300, or it may have a different shape. For example, the cross-section of the chamber and the outer shape of the capsule 1300 may both be oval. In another example, the cross-section of the chamber may be other than oval (for example, rectangular), while the cross-section of the outer shape of the capsule 1300 may be oval (and vice versa).

[0158] Figure 39 is a cross-sectional view of the capsule of Figure 37. As shown in Figure 39, the middle section 1344 of the heater 1340 is an internal segment configured to heat the aerosol-generating material inside the capsule 1300. The aerosol-generating material for capsule 1300 may be the same as that described in relation to the aerosol-generating materials for capsules 200 and 1200. The first end 1342 and the second end 1346 of the heater 1340 are external segments configured to establish an electrical connection to a power source (e.g., an electrical connection to power source 150 via electrical contacts 152a and 152b).

[0159] In addition to the second opening 1322, the second end cap 1320 also defines an alignment recess 1326 and an inlet recess 1328. The alignment recess 1326 and the inlet recess 1328 can be considered as multi-level structures. The base / internal end face of the alignment recess 1326 (exposing the first end 1342 and the second end 1346) can be considered as one level, and the base / internal end face of the inlet recess 1328 (or the grille-like surface of the second opening 1322) can be considered as another level. The alignment recess 1326 is configured to facilitate the positioning of the capsule 1300 when inserting it into the device body of the aerosol generating device. In one exemplary embodiment, the alignment recess 1326 has an angled side wall that tapers inward as it approaches the inlet recess 1328. Because the alignment recess 1326 has an angled side wall, it can be very easily and quickly coupled to the corresponding engaging member of the device body. For example, when received in the capsule receiving cavity 130 of the aerosol generating device 100, the alignment recess 1326 of the capsule 1300 can engage with the angled surface 176, and the inlet recess 1328 of the capsule 1300 can engage with the capsule seal 202. As a result, the capsule 1300 can be properly loaded into the body of the aerosol generating device and can be positioned relatively consistently.

[0160] Figure 40 is an exploded view of the capsule of Figure 37. As shown in Figure 40, the first end cap 1310 includes a first sealing ridge 1314, and the second end cap 1320 includes a second sealing ridge 1324. In one exemplary embodiment, the first sealing ridge 1314 is in the form of a series of ribs (e.g., four ribs), and the second sealing ridge 1324 is in the form of a series of ribs (e.g., four ribs). In some examples, the individual ribs in each arrangement may have different heights to ensure desirable contact with the cover 1330. When the capsule 1300 is assembled, the first sealing ridge 1314 of the first end cap 1310 and the second sealing ridge 1324 of the second end cap 1320 are configured to provide a sealed state by interface with the inner surface of the cover 1330 (e.g., via interference fits). As a result, when air is directed towards capsule 1300 during the operation of the aerosol generating device, the air enters capsule 1300 through the inlet recess 1328 and second opening 1322 in the second end cap 1320 (and not through the gap between the second end cap 1320 and cover 1330, in which case the air could essentially simply flow along the inner surface of cover 1330, bypassing the aerosol-generating material and / or intermediate portion 1344 of heater 1340). Similarly, provided a proper seal is provided, the aerosol generated in the chamber of capsule 1300 is drawn out through the first opening 1312 in the first end cap 1310 (and not leaks out through the gap between the first end cap 1310 and cover 1330).

[0161] The first end cap 1310 and the second end cap 1320 may be configured to facilitate their introduction into the cover 1330 by including lead-in features. For example, the first end cap 1310 may have a distal end with a periphery in the form of a tapered edge. Similarly, the second end cap 1320 may have a proximal end with a periphery in the form of a tapered edge. Such a configuration may facilitate the insertion of the first end cap 1310 and the second end cap 1320 into the cover 1330 (e.g., by press-fitting) during the assembly of the capsule 1300.

[0162] Figure 41 shows only the heater of Figure 40. As shown in Figure 41, the heater 1340 includes a first end 1342, an intermediate section 1344, and a second end 1346. The intermediate section 1344 of the heater 1340 may have a planar and convex shape resembling compression vibration or zigzag, having a plurality of mutually parallel segments (e.g., 8 to 16 mutually parallel segments). In one exemplary embodiment, the two outermost mutually parallel segments of the intermediate section 1344 may be wider than the mutually parallel inner segments to provide thermal relief and mechanical stiffness (e.g., 0.60 mm vs. 0.30 mm). Furthermore, the mutually parallel inner segments of the intermediate section 1344 may be closer to the first opening 1312 of the first end cap 1310 and the second opening 1322 of the second end cap 1320 than the mutually parallel outer segments of the intermediate section 1344. Such a configuration can facilitate heating in the central part of the capsule 1300. However, it should be understood that other forms (e.g., spiral form, floral form) are also possible for the intermediate part 1344 of the heater 1340.

[0163] The endpoints of the first end 1342 and the second end 1346 can be oriented perpendicular to the plane of the intermediate portion 1344. Each of the first end 1342 and the second end 1346 may further have a segment having a J-shaped side surface. Furthermore, each of the first end 1342 and the second end 1346 may include opposing finger / nail-like structures. The finger / nail-like structures may act as placement features for manufacturing equipment (e.g., an overmolding tool). As a result, the first end 1342 and the second end 1346 can be embedded relatively stably within the second end cap 1320 while providing a pair of electrical contact surfaces.

[0164] Figure 42 is a perspective view of a modified example of the heater in Figure 41. As shown in Figure 42, the heater 1340' includes a first end 1342', an intermediate section 1344', and a second end 1346'. The first end 1342', intermediate section 1344', and second end 1346' of the heater 1340' may be the same as those described for the first end 1342, intermediate section 1344, and second end 1346 of the heater 1340, respectively, unless otherwise noted. For example, one difference is that the transition from the intermediate section 1344' to the first end 1342' and second end 1346' may involve little or no change in dimensions (for example, the width is constant, whereas the section shown in Figure 41 is wider to achieve thermal relief / low resistance). Furthermore, each of the first end 1342' and the second end 1346' may include a tab simplified as an anchor structure and an electrical contact structure.

[0165] Figure 43 is a downstream perspective view of another capsule for an aerosol generating device according to an exemplary embodiment. In general, capsule 1400 shares commonalities (e.g., features, properties, constituent materials, and manufacturing methods) with capsule 1300. Therefore, unless otherwise specified, it should be understood that capsule 1400 may have aspects similar to those disclosed with respect to capsule 1300. As shown in Figure 43, capsule 1400 has a housing that includes a downstream portion in the form of a first end cap 1410 (e.g., a downstream cap) defining a first opening 1412, an upstream portion in the form of a second end cap 1420 (e.g., an upstream cap, connector cap), and a main body portion between them in the form of a cover 1430 (e.g., a shell, box sleeve). Regarding modifications of the shape shown herein, it should be understood that in some examples, capsule 1400 may have a rectangular parallelepiped shape with a rectangular cross-section (e.g., a rectangular parallelepiped other than a cube with rounded corners) instead of the shape shown herein. In other examples, the capsule 1400 may have an egg-shaped or ellipsoidal shape with an egg-shaped or elliptical cross-section. The chamber defined within the capsule 1400 may have the same shape as the outer shape of the capsule 1400, or it may have a different shape. For example, both the cross-section of the chamber and the outer shape of the capsule 1400 may be oval. In another example, the cross-section of the chamber may be other than oval (e.g., rectangular) and the cross-section of the outer shape of the capsule 1400 may be oval (and vice versa).

[0166] As illustrated, the first end cap 1410 and the second end cap 1420 may lack rectangular recesses (e.g., gating features) that are present in some other embodiments (e.g., compared to the capsule 1300 in Figure 37) as a result of the manufacturing process. Furthermore, while the sides of the first end cap 1410 and the second end cap 1420 may be substantially flush with the surface of the adjacent cover 1430, it should be understood that other modifications are also possible. For example, in some examples, the protruding edge / flange of the first end cap 1410 (which functions as a hard stop on the cover 1430) may be greater than the wall thickness of the cover 1430, and therefore the adjacent surfaces of the first end cap 1410 and the cover 1430 may not be flush or substantially flush. In another example, the protruding edge / flange of the second end cap 1420 (which functions as a hard stop for the cover 1430) may be greater than the wall thickness of the cover 1430, so that the adjacent surfaces of the second end cap 1420 and the cover 1430 do not have to be flush or substantially flush. In yet another example, the protruding edges / flanges of both the first end cap 1410 and the second end cap 1420 may be greater than the wall thickness of the cover 1430, so that the adjacent surfaces of the first end cap 1410 and the cover 1430 do not have to be flush or substantially flush, and the adjacent surfaces of the second end cap 1420 and the cover 1430 do not have to be flush or substantially flush.

[0167] In another variation, the first end cap 1410 and / or the second end cap 1420 may be configured to fit entirely within the cover 1430. For example, the downstream end face of the first end cap 1410 may be flush (or substantially flush) with the downstream edge of the cover 1430. Similarly, the upstream end face of the second end cap 1420 may be flush (or substantially flush) with the upstream edge of the cover 1430.

[0168] Figure 44 is a downstream perspective view of another capsule for an aerosol generating device according to an exemplary embodiment. In general, capsule 1500 shares commonalities with capsule 1300 (e.g., features, properties, constituent materials, and manufacturing methods). Therefore, unless otherwise specified, it should be understood that capsule 1500 may have aspects similar to those disclosed with respect to capsule 1300. As shown in Figure 44, capsule 1500 has a housing that includes a downstream portion in the form of a first end cap 1510 (e.g., a downstream cap) defining a first opening 1512, an upstream portion in the form of a second end cap 1520 (e.g., an upstream cap, connector cap), and a main body portion between them in the form of a cover 1530 (e.g., a shell, box sleeve). Regarding variations of the shape shown herein, it should be understood that in some examples, the shape that capsule 1500 may have may be different from the shape shown herein, with its outer end view or cross-section resembling a rectangle (e.g., elongated circle, oval, capsule tablet shape, stadium shape, racetrack shape), oval / egg shape, or ellipse) having a pair of opposing semicircular ends.

[0169] As illustrated, the first end cap 1510 and the second end cap 1520 may overlap with the cover 1530. Specifically, the periphery of each of the first end cap 1510 and the second end cap 1520 may be larger than the periphery of the cover 1530, thereby allowing the opposing ends of the cover 1530 to be received by the first end cap 1510 and the second end cap 1520. In such an example, the first end cap 1510 and the second end cap 1520 may interface with the outer surface of the cover 1530. In another example, the first end cap 1510 and the second end cap 1520 may interface with both the outer and inner surfaces of the cover 1530. In either example, the first end cap 1510 and the second end cap 1520 may include sealing ridges configured to provide a desired seal by interface with the cover 1530. Furthermore, the overlapping configuration in Figure 44 may provide improved ergonomics by allowing the capsule 1500 to be grasped and handled more carefully.

[0170] Figure 45 is a downstream perspective view of another capsule for an aerosol generating device according to an exemplary embodiment. In general, capsule 1600 shares commonalities with capsule 1500 (e.g., features, properties, constituent materials, manufacturing method). Therefore, unless otherwise specified, it should be understood that capsule 1600 may have aspects similar to those disclosed with respect to capsule 1500. As shown in Figure 45, capsule 1600 has a housing that includes a downstream portion in the form of a first end cap 1610 (e.g., downstream cap) defining a first opening 1612, an upstream portion in the form of a second end cap 1620 (e.g., upstream cap, connector cap), and a main body portion between them in the form of a cover 1630 (e.g., shell, box sleeve). Regarding variations of the shape shown herein, it should be understood that in some examples, the shape that capsule 1600 may have may be different from the shape shown herein, with its outer end view or cross-section resembling a rectangle (e.g., elongated circle, oval, capsule tablet shape, stadium shape, racetrack shape), oval / egg shape, or ellipse) having a pair of opposing semicircular ends.

[0171] As shown in the figure, the first end cap 1610 may overlap with the cover 1630. Specifically, the periphery of the first end cap 1610 may be larger than the periphery of the cover 1630, thereby allowing the proximal end of the cover 1630 to be received by the first end cap 1610. In such an example, the first end cap 1610 may interface with the outer surface of the cover 1630, and the second end cap 1620 may interface with the inner surface of the cover 1630. Conversely, in another example, the first end cap 1610 may interface with the inner surface of the cover 1630, and the second end cap 1620 may interface with the outer surface of the cover 1630. In either example, the first end cap 1610 and the second end cap 1620 may include sealing ridges configured to provide a desired seal by interface with the cover 1630. Furthermore, the overlapping configuration in Figure 45, in which the first end cap 1610 overlaps with the cover 1630, can help ensure the correct orientation of the capsule 1600 when it is loaded into the device body of the aerosol generating device (for example, by limiting the options for the orientation in which the capsule 1600 can be loaded).

[0172] Figure 46 is a downstream perspective view of another capsule for an aerosol generating device according to an exemplary embodiment. In general, capsule 1700 shares commonalities with capsule 1500 (e.g., features, properties, constituent materials, manufacturing method). Therefore, unless otherwise specified, it should be understood that capsule 1700 may have aspects similar to those disclosed with respect to capsule 1500. As shown in Figure 46, capsule 1700 has a housing that includes a downstream portion in the form of a first end cap 1710 (e.g., downstream cap) defining a first opening 1712, an upstream portion in the form of a second end cap 1720 (e.g., upstream cap, connector cap), and a main body portion between them in the form of a cover 1730 (e.g., shell, box sleeve). Regarding variations of the shape shown herein, it should be understood that in some examples, the shape that capsule 1700 may have may be different from the shape shown herein, with its outer end view or cross-section resembling a rectangle (e.g., elongated circle, oval, capsule tablet shape, stadium shape, racetrack shape), oval / egg shape, or ellipse) having a pair of opposing semicircular ends.

[0173] As illustrated, the cover 1730 may be a composite structure comprising an inner shell and an outer wrapper. The inner shell of the cover 1730 may be formed of metal / alloy or high-temperature plastic, and the outer wrapper of the cover 1730 may be formed of insulating material and / or fibrous material (e.g., pulp / cork wrapper, paper label). For example, the material of the outer wrapper of the cover 1730 may allow printing (e.g., branding / aesthetic information or other information). When the capsule 1700 is assembled, the sides of the first end cap 1710 and the second end cap 1720 may be substantially flush with the surface of the adjacent cover 1730. Furthermore, the composite structure of the cover 1730 may improve the thermal properties (e.g., thermal insulation for safer handling) and / or aesthetic properties of the capsule 1700.

[0174] Figure 47 is a perspective view of an integrated aerosol-generating material according to an exemplary embodiment. As shown in Figure 47, the aerosol-generating material 1860 can be made easier to load during capsule assembly by comprising a first aerosol-generating material 1860a and a second aerosol-generating material 1860b. Each of the first aerosol-generating material 1860a and the second aerosol-generating material 1860b may be in an integrated form and configured to be uniformly arranged within the capsule chamber by maintaining its shape. For example, the first aerosol-generating material 1860a and the second aerosol-generating material 1860b may be in the form of rectangular sheets / slabs adjusted to dimensions such as being inserted into capsule 1200. Specifically, the first aerosol-generating material 1860a and the second aerosol-generating material 1860b can be inserted into the cover 1230 during assembly / loading so that they are located on both sides of the intermediate portion 1244 of the heater 1240 (e.g., with the intermediate portion 1244 sandwiched between them). Based on the shape and dimensions of the first aerosol-generating material 1860a and the second aerosol-generating material 1860b, the aerosol-generating material 1860 may occupy all or substantially all of the usable space within the chamber defined by the inner surfaces of the first end cap 1210, the second end cap 1220, and the cover 1230.

[0175] Figure 48 is a perspective view of another aerosol-generating material in an integrated form according to an exemplary embodiment. As shown in Figure 48, the aerosol-generating material 1860' may differ from the aerosol-generating material 1860 in shape and dimensions. In other respects, the aerosol-generating material 1860' may be the same as that described for the aerosol-generating material 1860. For this reason, the similarities described above may not be repeated for brevity. The aerosol-generating material 1860' may include a first aerosol-generating material 1860a' and a second aerosol-generating material 1860b', each of which may be in an integrated form. For example, the first aerosol-generating material 1860a' and the second aerosol-generating material 1860b' may be in the form of a slab / pallet having a semi-elliptical cross-section adjusted to dimensions that allow it to be inserted into the capsule 1300. Specifically, the first aerosol-generating material 1860a' and the second aerosol-generating material 1860b' can be inserted into the cover 1330 during assembly / loading so that they are located on both sides of the intermediate portion 1344 of the heater 1340 (e.g., with the intermediate portion 1344 sandwiched between them). Based on the shape and dimensions of the first aerosol-generating material 1860a' and the second aerosol-generating material 1860b', the aerosol-generating material 1860' can occupy all or substantially all of the usable space within the chamber defined by the inner surfaces of the first end cap 1310, the second end cap 1320, and the cover 1330 (because the resulting shape and dimensions have an oval cross-section corresponding to the cross-section of the chamber).

[0176] Figure 49 is a perspective view of a loose form of aerosol-generating material according to an exemplary embodiment. As shown in Figure 49, the aerosol-generating material 1860” may be in a loose form (e.g., particles, fibers, powder, flakes, fragments) that does not have a set shape and is configured to take the shape of the usable space in the chamber when introduced into the capsule. Specifically, the loose form of the aerosol-generating material 1860” may occupy part or all of the usable space in the chamber of the capsule during assembly / loading, such as being present on both sides of the intermediate part of the heater (e.g., surrounding and in contact with the intermediate part 1344 of the heater 1340). For example, the loose form of the aerosol-generating material 1860” may be used to fill the rest of the chamber (e.g., the top of the chamber) of a chamber that has already been loaded with an integrated form of aerosol-generating material. In another example, the loose form of the aerosol-generating material 1860” may be used to fill the entire chamber of the capsule. Furthermore, the aerosol-generating material 1860" may be loaded into capsules (e.g., capsule 1200, capsule 1300) by a vacuum-assisted process.

[0177] Figure 50 is a block diagram of an aerosol generating device according to an exemplary embodiment. In one example, the aerosol generating device may be aerosol generating device 100. In another example, the aerosol generating device may be aerosol generating device 500. Unless otherwise noted, the details of the block diagram are applicable to both aerosol generating device 100 and aerosol generating device 500.

[0178] As shown in Figure 50, according to at least one exemplary embodiment, the control subsystem 2100 may include, but is not limited to, a controller 2105, a power supply 2110, an actuator control 2115, a capsule electrical / data interface 2120, a device sensor 2125, an input / output (I / O) interface 2130, an aerosol indicator 2135, at least one antenna 2140, and / or a storage medium 2145. For example, the control subsystem 2100 may include additional elements, which are not described for brevity. In another exemplary embodiment, the capsule electrical / data interface 2120 may be an electrical interface only, for example.

[0179] The controller 2105 may be a combination of hardware and software, such as hardware including logic circuits, a processor that runs software, or a combination of these. For example, the controller 2105 may include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field-programmable gate array (FPGA), a system-on-a-chip (SoC), a programmable logic unit, a microprocessor, or an application-specific integrated circuit (ASIC).

[0180] In events in which the controller 2105 is process execution software or includes process execution software, the controller 2105 is configured to perform its functions as a dedicated machine (e.g., a processing device) by executing software stored in memory accessible to the controller 2105 (e.g., storage medium 2145 or other storage device). The software may be embodied as program code containing instructions that execute and / or control any or all of the operations described herein as being performed by the controller 2105.

[0181] In this specification, the terms “storage medium,” “computer-readable storage medium,” or “non-temporary computer-readable storage medium” mean one or more devices that store data, including read-only memory (ROM), random-access memory (RAM), magnetic RAM, core memory, magnetic disk storage medium, optical storage medium, flash memory medium, and / or other tangible machine-readable media for storing information. The term “computer-readable medium” may include, but is not limited to, portable or fixed storage medium, optical storage medium, and various other media that can store, contain, or carry instructions and / or data.

[0182] The controller 2105 communicates with the power supply 2110, actuator control 2115, electrical / data interface 2120, device sensor 2125, input / output (I / O) interface 2130, aerosol indicator 2135, on-product control 2150, and / or at least one antenna 2140, etc. According to at least some exemplary embodiments, the on-product control 2150 may include a device that can be operated by an adult operator to indicate a choice of values. Example implementations include, but are not limited to, one or more buttons, dials, capacitive sensors, sliders, etc.

[0183] The controller 2105 (or storage medium 2145) stores key materials and proprietary algorithms for encryption. For example, the encryption algorithm relies on the use of random numbers. The security of these algorithms depends on how truly random these numbers are. These numbers are usually pre-generated and coded into a processor or memory device. Exemplary embodiments may increase the randomness of the numbers used for encryption by using aerosol inhalation parameters, e.g., the duration of aerosol inhalation, the interval between aerosol inhalations, or a combination thereof, thereby generating numbers that are more random and diverse than pre-generated random numbers. All communication between the controller 2105 and the capsule 200 may be encrypted.

[0184] The controller 2105 is configured to run a real-time operating system (RTOS) and control the control subsystem 2100, and can be updated by reading and / or sensing update information from tags, chips and / or labels (e.g., security tags, security chips, etc.) contained in the capsule 200. The reading and / or sensing is performed via communication with an NVM or CC-NVM and / or when the control subsystem 2100 is connected to other devices (e.g., smartphones) via the I / O interface 2130 and / or antenna 2140. For example, the update information may include parameter information for the corresponding capsule, e.g., heater parameter information and / or heater profile information tailored to and / or directed to the aerosol-generating material contained in the installed capsule 200, a combination of capsule authentication update information and information about the capsule authentication method (e.g., security settings for the capsule, updates to the security key used during authentication, etc.), programming updates, etc. Furthermore, the I / O interface 2130 and antenna 2140 enable the control subsystem 2100 to connect to various external devices, e.g., smartphones, tablets, PCs, etc. For example, the I / O interface 2130 may include a USB-C connector, a micro USB connector, etc. The USB-C connector (e.g., connector port 114) may be used by the control subsystem 2100 to charge the power supply 2110b (e.g., which may correspond to power supply 150), and the USB-C connector may also be used to send and receive data with at least one external device, but the exemplary embodiments are not limited to these. The data mentioned above may include, for example, aerosol profiles, heater profiles, device performance log data (e.g., controller performance data, memory performance data, battery performance data, heater performance data, etc.), firmware updates, software updates, etc.

[0185] The controller 2105 may store and execute code, including analysis, diagnosis, and software updates, by including onboard ROM and flash memory. Alternatively, the storage medium 2145 may store code. Furthermore, in another exemplary embodiment, the storage medium 2145 may be mounted on the controller 2105.

[0186] The controller 2105 can further reduce the area covered by the PCB within the device housing by including onboard clock, reset, and power management modules.

[0187] The device sensor 2125 may include a plurality of sensor transducers that provide measurement information to the controller 2105. The device sensor 2125 may monitor motion and orientation by including a power supply temperature sensor, an external capsule temperature sensor, a heater current sensor, a power supply current sensor, an airflow sensor, and an accelerometer. The power supply temperature sensor and the external capsule temperature sensor may be thermistors or thermocouples, and the heater current sensor and the power supply current sensor may be resistance-based sensors or other types of sensors configured to measure current. The airflow sensor (e.g., flow sensor 185) may be a pressure sensor (e.g., a capacitive pressure sensor) configured to detect positive or negative air pressure (e.g., suction or puff), a microelectrochemical system (MEMS) flow sensor, and / or other types of sensors configured to measure airflow, such as a hot-wire anemometer. Furthermore, the airflow may be measured using a hot-wire anemometer 2220A located inside the capsule 200, instead of using a flow sensor included in the device sensor 2125 of the control subsystem 2100 of the housing of the device body, or in addition to this. According to at least one exemplary embodiment, the device sensor 2125 further includes a capsule detection sensor for detecting the presence of a capsule inside the aerosol generating device 100, and / or a door detection sensor for detecting whether the door and / or lid of the aerosol generating device is closed, but the exemplary embodiment is not limited thereto.

[0188] Data generated from one or more device sensors 2125 can be detected based on binary signals (e.g., on / off signals) using general-purpose input / output (GPIO) circuits, and / or sampled at a sample rate suitable for the parameter being measured, for example, using a discrete multi-channel analog-to-digital converter (ADC).

[0189] Furthermore, according to at least one exemplary embodiment, the device sensor may further include a tag sensor such as a barcode sensor, a secure element (SE) reader, an optical reader, a physical parameter reader, and the like. The tag sensor and / or tag antenna (e.g., an RFID antenna, an NFC antenna, etc.) may be used alone or in combination to detect information stored on a tag (e.g., an RFID tag, an NFC tag, a barcode tag, an SE, etc.) installed and / or attached to the outside of the capsule 200, and / or to detect and / or sense physical parameters of the capsule 200, such as the resistance value of a heater contained within the capsule 200. The tag sensor and / or tag antenna may be positioned in physical proximity to the properly inserted capsule 200, thereby detecting information stored on the tag, such as electronic identification information, authentication information, hardware parameter information, aerosol-generating substance information (e.g., aerosol-generating substance expiration date information, manufacturing date information, etc.), profile information, etc.

[0190] The controller 2105 may apply a heater profile for the aerosol-generating substance and other profiles based on measurement information received from the controller 2105. For convenience, these are collectively referred to as the aerosol profile. The heater profile identifies the power profile supplied to the heater during the few seconds when aerosol aspiration occurs, and / or the power profile supplied to the heater between aerosol aspirations. This is to continuously heat the capsule (for example, to provide an "oven mode" in which a desired temperature is maintained within the capsule for a desired period of time). For example, the heater profile may deliver maximum power to the heater when aerosol aspiration begins, but then reduce the power by half or a quarter about 1 second later. According to at least some exemplary embodiments, modulation of the power supplied to the heater may be performed using pulse width modulation, but is not limited to this.

[0191] Furthermore, the heater profile may be modulated based on the detection of suction and / or negative pressure application to the aerosol generating device 100. By using a flow sensor, the intensity of aerosol suction can be measured and used as feedback to the controller 2105. This adjusts the power delivered to the heater of the capsule 200, which can be called heating or energy delivery.

[0192] According to at least some exemplary embodiments, when the controller 2105 recognizes the currently installed capsule 200 (e.g., via SKU, via a unique identifier contained in a tag (e.g., RFID tag, NFC tag, etc.)), the controller 2105 matches the relevant heating profile designed for that particular capsule. The controller 2105 and the storage medium 2145 store data and algorithms that enable the generation of heating profiles for all SKUs, all capsule types, all types of aerosol-generating materials, etc. In another exemplary embodiment, the controller 2105 may read the heating profile from the capsule. Furthermore, an adult operator may adjust the heating profile to their liking using the on-product control 2150, an external device wirelessly paired with the aerosol-generating device 100 and / or an external device connected to the aerosol-generating device 100 via an I / O interface 2130, etc. In another exemplary embodiment, the controller 2105 may use a heating profile that was applied to the previously installed capsule and is stored in memory for the currently installed capsule. This is done on the premise that the current capsule is the same type as the previously installed capsule.

[0193] The controller 2105 can send and receive data with the power supply 2110. The power supply 2110 includes a power supply 2110b (which may correspond to, for example, power supply 150) and a power controller 2110a, and the power output is managed by the power supply 2110b.

[0194] The power supply 2110b may be a lithium-ion battery or one of its modifications, such as a lithium-ion polymer battery. Alternatively, the power supply 2110b may be a nickel-metal hydride battery, a nickel-cadmium battery, a lithium-manganese battery, a lithium-cobalt battery, or a fuel cell. Alternatively, the power supply 2110b may be rechargeable and include a circuit that allows the battery to be charged by an external charging device. In this case, once charged, the circuit supplies power for a desired (or predetermined) number of aerosol inhalations. The circuit then must be reconnected to the external charging device.

[0195] The power controller 2110a issues commands to the power supply 2110b based on instructions from the controller 2105. For example, when a capsule is detected and an adult operator activates the control subsystem 2100 (e.g., by activating a switch such as a toggle button, capacitive sensor, or IR sensor), the power supply 2110 may receive a command from the controller 2105 to supply power to the capsule (via the capsule electrical / data interface 2120). Furthermore, according to at least some exemplary embodiments, the controller 2105 may send its command to the power supply 2110 based on the fact that the capsule has been properly authenticated, but exemplary embodiments are not limited thereto.

[0196] In addition to supplying power to the capsule, power supply 2110 also supplies power to controller 2105. Furthermore, power controller 2110a provides controller 2105 with feedback indicating the performance of power supply 2110b.

[0197] The controller 2105 transmits and receives data with at least one antenna 2140. The at least one antenna 2140 may include an NFC modem, a Bluetooth Low Energy (LE) modem, and / or other modems for wireless technology (e.g., Wi-Fi). In one exemplary embodiment, the communication stack resides within the modem, but the modem is controlled by the controller 2105. A Bluetooth LE modem is used for data and control communication with an application on an external device (e.g., a smartphone). An NFC / Bluetooth LE / Wi-Fi modem may be used to pair the aerosol generating device 100 for application and transmission of diagnostic information, data, profile information, capsule information, hardware parameter information, firmware updates, etc. Furthermore, a Bluetooth LE / Wi-Fi modem may be used to provide location information (for an adult operator to locate the aerosol generating device) or authentication during purchase, etc.

[0198] As described above, the control subsystem 2100 can generate and adjust various profiles for aerosol generation. The controller 2105 uses the power supply 2110 and actuator control 2115 to regulate the profile for adult operators.

[0199] The actuator control 2115 regulates a desired aerosol profile by including passive and active actuators. For example, the housing of the device body may include actuators within the air inlet passage and / or air inlet channel of the housing of the device body, for example, within the airflow subsystem of the aerosol generating device 100 (e.g., air channel assembly 181, air hose 180, air inlet connection 184, etc.). The actuator control 2115 can control the airflow in the air inlet channel using the actuators based on commands from the controller 2105 related to the desired aerosol profile.

[0200] Furthermore, the actuator control 2115 is used in conjunction with the power supply 2110 to supply energy to the heater. More specifically, the actuator control 2115 is configured to generate a drive waveform associated with a desired aerosol profile. As described above, each of the possible profiles is associated with a drive waveform. When the actuator control 2115 receives a command from the controller 2105 indicating a desired aerosol profile, it may generate the associated modulated waveform for the power supply 2110.

[0201] The controller 2105 provides information to the aerosol indicator 2135 to inform the adult operator of the situation and the actions currently being performed. The indicator 2135 includes a power indicator displayed on a display panel (e.g., communication screen 140), and a separate indicator light (e.g., an LED indicator light) that may be activated when the controller 2105 detects that the adult operator has pressed a button. The indicator 2135 may further include a haptic feedback motor, a speaker, an indicator showing the current state of aerosol parameters controlled by the adult operator (e.g., the volume of aerosol generated), and other feedback mechanisms.

It should be understood that relevant teachings / modifications for one capsule are applicable to other capsules unless otherwise noted. Furthermore, while aerosol generating devices 100 and 500 are disclosed configured to receive and heat capsule 200, it should be understood that aerosol generating devices 100 and 500 are also applicable to receiving and heating capsules 1200, 1300, 1400, 1500, 1600, 1700, and other modifications.
