For example, mouthpiece 160 may be attached using, without limitation, a snug fit, a detent, a clamp, a threaded connector, a slide fit, a sleeve fit, an alignment fit, a threaded connector, a magnetic, a clasp, or any type of connection, and / or combination thereof. When the bayonet connector is locked into place on the mouthpiece chassis of device body housing 101, haptic feedback (e.g., a click, increased resistance, etc.) may be provided to the adult operator to inform the adult operator that the mouthpiece has been properly connected to device body housing 101. In some exemplary embodiments, the mouthpiece 160 may be part of the proximal end piece 152 and / or the device body housing 101 and / or may be integrated with the proximal end piece 152 and / or the device body housing 101.

[0069] Additionally, according to some exemplary embodiments, mouthpiece 160 may further include at least one aerosol outlet 165B. While Figure 1E shows a single aerosol outlet 165, exemplary embodiments are not limited thereto. Multiple aerosol outlets may be provided in mouthpiece 160. Additionally, according to some exemplary embodiments, a diffuser may be provided to diffuse (e.g., separate) aerosol drawn from capsule 170 through the mouthpiece and the aerosol outlet(s) of the mouthpiece, etc.

[0070] According to some exemplary embodiments, the distal end piece 112, the rear outer piece 140, the front outer piece 107, the door 151 and the proximal end piece 152 define the outer shape of the device body of the aerosol generating device 100 and further define an internal space that houses the airflow subsystem, control subsystem and electrical subsystem of the aerosol generating device 100.

[0071] 2A to 2E show various views of the door assembly and mouthpiece assembly of an aerosol generating device according to some exemplary embodiments.

[0072] Reference is made to Figures 2A and 2B. Figure 2A is a side view of an aerosol generating device according to at least one exemplary embodiment, showing the door assembly in an open position. Figure 2B is a front and top perspective view of an aerosol generating device according to at least one exemplary embodiment, showing the door assembly in an open position. As shown in Figure 2A, the aerosol generating device 100 may include a device body housing 101, a door assembly (e.g., 1100) including a door 151, and a mouthpiece assembly (e.g., 1200) including a removable (e.g., separable) mouthpiece 160, although exemplary embodiments are not limited thereto. The device body housing 101 includes a proximal portion (e.g., upper portion 150 in Figure 1A) and an opposing distal portion (e.g., lower portion 105 in Figure 1A). The removable mouthpiece 160 is disposed in the proximal portion 150, and the distal end piece 112 is disposed in the distal portion 105. When the capsule 170 is inserted into the capsule receiving portion 175 and positioned in an operating position (e.g., when the door assembly is closed), the capsule 170 is disposed within the interior space of the device body housing 101 between the mouthpiece 160 and the distal end piece 112. For example, but not limited to, the inserted capsule 170 may be disposed in a proximal portion (e.g., 150 in FIG. 1A ) or a distal portion (e.g., 105 in FIG. 1A ) of the device body housing 101.

[0073] As shown in FIG. 2B , according to at least one exemplary embodiment, capsule 170 may include, but is not limited to, an aerosol-generating substance compartment (e.g., a plant material compartment, a substance compartment, etc.) and a heater. An air channel extends from the distal end of device main housing 101 (e.g., air inlet 113 in FIG. 1D ) to removable capsule 170 and can provide a flow of air from the outside to the capsule upon application of suction (e.g., a suction event) and / or application of negative pressure. The air channel may be in the form of one or more channels extending from air inlet 113 of main housing 101 through distal portion 105. The aerosol-generating substance compartment is configured to hold aerosol-generating substance (e.g., plant material) therein. The aerosol-generating substance is a material or combination of materials that is heated by the heater to generate an aerosol. The capsule and aerosol-generating substance are described in more detail with reference to FIGS. 9A-9C .

[0074] A heater (described in more detail below with reference to FIGS. 9A-9C ) is disposed within the at least one capsule 170 and device body housing 101. The aerosol-generating material compartment of the capsule is configured to be in fluid communication with the heater during operation of the aerosol generation device 100, such that the aerosol-generating material from the aerosol-generating material compartment is in thermal contact with the heater. The heater is configured to produce an aerosol by heating the aerosol-generating material, which passes through the aerosol-generating material compartment and reaches the mouthpiece 160 via at least one aerosol flow path 165 and at least one aerosol outlet 165B of the mouthpiece chimney 161 (shown in FIG. 2E ). At least one air hose 116 of the device body housing 101 is inserted into, connected to, and / or engaged with the distal end of the capsule 170 via the capsule connector 177, such that the air inlet of the capsule 170 is aligned with the air hose 116 of the device body housing 101 when the capsule 170 is in the operating position.

[0075] Additionally, at least one aerosol chimney 161 for the mouthpiece 160 is configured to connect, mate, and / or engage with the proximal end of the capsule, thereby aligning the capsule's aerosol outlet with the aerosol flow path 165, thereby facilitating delivery of generated aerosol through the chimney 161 to the mouthpiece 160. The chimney 161 may be an elongated portion of the mouthpiece 160 and defines at least one aerosol flow path 165 in the form of one or more flow paths extending through the mouthpiece 160. According to some exemplary embodiments, the aerosol flow path 165 and the chimney 161 together form the mouthpiece 160, pass through at least one opening (e.g., opening 154 in FIG. 4A ) in the proximal end 152 of the device body housing 101, and mate, connect, and / or engage with the proximal end of the capsule. The mouthpiece is described in more detail below.

[0076] 2C and 2D. FIG. 2C is a side view of the internal structure of the proximal end of the aerosol generating device in an open state. FIG. 2D is a side view of the internal structure of the proximal end of the aerosol generating device in a closed state. For simplicity, the door chassis has been omitted. According to at least one exemplary embodiment, the aerosol generating device 100 includes, but is not limited to, a door assembly (e.g., the door assembly 1100 in FIG. 3A ) and a mouthpiece assembly (e.g., the mouthpiece assembly 1200 in FIG. 4A ). The door assembly may include, but is not limited to, a door 151, a door chassis 153 attached to the door 151, a capsule receiving portion 175 movably connected to the door chassis 153 via a pair of rails 157 defined on the door chassis 153, and a capsule connector 177 attached to the door 151 via the door chassis 153.

[0077] According to at least one exemplary embodiment, mouthpiece assembly 1200 may include mouthpiece chassis 155 in addition to mouthpiece 160 and mouthpiece chimney 161. Mouthpiece chassis 155 is movably connected to chassis 147 via a pair of slots 148 and pin 149A, and via at least one spring 123 that contacts proximal end piece 152 and biases against mouthpiece chassis 155, etc., although exemplary embodiments are not limited in this respect. That is, any sliding engagement structure, such as a rail, race, bushing, etc., may be used in place of the slot and pin structure.

[0078] The door assembly 1100 and the door 151 of the aerosol generating device 100 can generally be lifted, rotated, pivoted, moved, pushed, pulled, etc. about the hinges 120 to an open position (e.g., an open state) or a closed position (e.g., a closed state). According to some exemplary embodiments, an adult operator can manually actuate the door 151 and the door assembly 1100 to move them to the open and / or closed positions, although exemplary embodiments are not limited thereto. For example, the door 151 and the door assembly 1100 may be moved to the open or closed position using a motor, a magnetic lock, or other comparable device. When the door 151 (and by extension the door assembly 1100) is in the open position, the capsule receiver 175 is moved to the proximal end of the door 151 by at least one first linkage 121, and the capsule 170 can be inserted into the capsule receiver 175. Simultaneously, the at least one second linkage 122 laterally moves the mouthpiece assembly 1200, including the mouthpiece chassis 155, thereby moving the attached mouthpiece 160 away from the proximal end of the device body housing 101 (e.g., moving the mouthpiece 160 away from the proximal end piece 152 to an extended position and / or state), thereby disengaging the mouthpiece 160 from the capsule 170 and allowing the capsule 170 to be conveniently and efficiently removed from the body housing 101.

[0079] Additionally, when door 151 is in the open position, door assembly 1100 and mouthpiece assembly 1200 compress at least one compression spring 123. According to some exemplary embodiments, two or more compression springs 123 may be disposed on U-shaped spring mounts 123A (e.g., spring frames, etc.) included in the base of body chassis 147 on the left and right sides of mouthpiece chassis 155, although exemplary embodiments are not limited thereto. In response to door 151 moving to the closed position and second linkage 122 moving, at least one compression spring 123 moves mouthpiece assembly 1200, including mouthpiece chassis 155, laterally and retracts (e.g., moves, pushes, etc.) mouthpiece 160 toward the distal end of device body housing 101 (e.g., moving mouthpiece 160 to a closed / retracted position and / or state). Additionally, as mouthpiece 160 moves to the closed position, mouthpiece chimney 161 engages capsule 170. Movement of door assembly 1100 and mouthpiece assembly 1200 is described in more detail below with reference to Figures 5A-5C and 6A-6C.

[0080] Reference is made to Figures 2C to 2E. Figure 2C is a side view of the internal structure of the proximal end of the aerosol generating device in an open state. Figure 2D is a side view of the internal structure of the proximal end of the aerosol generating device in a closed state, with the door chassis omitted for clarity. Figure 2E is a cross-sectional view of the proximal end of the aerosol generating device in an open state.

[0081] As shown in FIGS. 2C to 2E , according to at least one exemplary embodiment, a stationary main body chassis 147 is disposed along the lower interior of the device main body housing 101, providing an internal frame for the aerosol generating device 100. According to at least one exemplary embodiment, the main body chassis 147 includes a rear base frame 147A and one or more vertical frame members (e.g., 147B and 147C) that provide structure for the aerosol generating device 100, although exemplary embodiments are not limited thereto. According to some exemplary embodiments, the main body chassis 147 may further include a front base frame and a rear base frame, and / or one of the front base frame and the rear base frame may be omitted. Furthermore, the outer pieces of the device main body housing 101, such as the distal end piece 112, the rear outer piece 140, the front outer piece 107, the door 151, and / or the proximal end piece 152, may be mounted to the main body chassis 147 using bosses, or may be attached, connected, welded, screwed, clipped, and / or fastened. Additionally, internal elements of the aerosol generating device 100, such as the power subsystem, airflow subsystem, and / or control subsystem, may be mounted to the main chassis 147 using bosses, or may be attached, connected, welded, screwed, clipped, and / or fastened.

[0082] According to at least one exemplary embodiment, the mouthpiece chassis 155 is further movably attached to the stationary body chassis 147. For example, the mouthpiece chassis 155 is connected to the body chassis 147 via a pair of slots 148 on both sides (e.g., left and right sides) of the body chassis 147, such that the mouthpiece chassis 155 can move (e.g., slide) longitudinally of the aerosol generation device 100 (e.g., move between the distal end and the proximal end, etc.) using a pin 149A of the mouthpiece chassis inserted into the slot 148.

[0083] Additionally, mouthpiece chassis 155 and proximal end piece 152 of device body housing 101 include a mouthpiece opening 154 configured to receive a chimney 161 of mouthpiece 160. Chimney 161 is an elongated portion of mouthpiece 160 that, when mouthpiece 160 and capsule 170 are installed in device body housing 101, defines at least one aerosol flow path 165 between at least one opening in the proximal end of the mouthpiece and the proximal end of capsule 170. While the figures show chimney 161 as having a tubular shape, exemplary embodiments are not so limited and chimney 161 may have any shape.

[0084] As shown in Figures 2C to 2E, the main body chassis 147 may include a pair of parallel slots 148. The slots 148 have a desired length corresponding to the travel distance of the door 151 (e.g., the distance the door 151 travels between an open and closed state) and are disposed at the proximal end of the aerosol generating device 100 in the same direction as the orientation of the mouthpiece 160 relative to the main body housing 101 (e.g., on the right and left sides of the main body chassis 147 and extending longitudinally through the main body housing 101). For example, as shown in Figures 2C to 2E, the slots 148 are elongated horizontal openings in the vertical member 147C of the main body chassis 147, although the exemplary embodiment is not limited thereto. The slots 148 may be positioned in different positions and / or have different shapes or configurations, etc.

[0085] According to some exemplary embodiments, mouthpiece chassis 155 engages with a pair of slots 148 in body chassis 147, such that mouthpiece chassis 155 can move and / or slide along pair of slots 148 in response to the opening and closing of door 151 of door assembly 1100. Door 151 opens and closes in response to movement of linkage 122 and the bias of compression spring 123. Additionally, mouthpiece chassis 155 may move in response to a lateral force (e.g., a horizontal force, etc.) being applied to mouthpiece 160, although exemplary embodiments are not limited thereto.

[0086] 2C to 2E, the body chassis 147 is connected to at least one first linkage 121 via a first pivot 146A (e.g., a ball joint, a pin, etc.) inserted into a vertical support 147B of the body chassis 147, and the mouthpiece chassis 155 is connected to at least one second linkage 122 via a second pivot 149A (e.g., a ball joint, a pin, etc.). The second pivot 149A is inserted into a slot 148 (e.g., an elongated horizontal slot) in the vertical support 147C of the body chassis 147 and an opening in the second linkage 122. Each of the first linkage 121, the first pivot 146A, the second linkage 122, and / or the second pivot 149A may be, but is not limited to, a pair of linkages or pivots located on the left and right sides of the body chassis 147 and the mouthpiece chassis 155, respectively.

[0087] The first linkage 121 can be an angled or elbow-type linkage (e.g., having an angle less than 90 degrees), and the second linkage 122 can be a straight (e.g., linear) linkage. The length of the first linkage 121 is longer than the second linkage 122 to open the proximal end of the capsule receiver 175 and the door 151, but this is not a limitation of the exemplary embodiment. The linkages may have different shapes or lengths. The first linkage 121 is fixedly or rotatably attached to the body chassis 147 at a proximal end of the body chassis 147, and the second linkage 122 is fixedly or rotatably attached to the distal end of the door chassis 153, but this is not a limitation of the exemplary embodiment.

[0088] The second linkage 122 and the second pivot 149A may move laterally within the slot 148 in response to the opening and closing of the door 151. And / or the second linkage 122 may provide an auxiliary force to open and close the door 151 in response to the second pivot 149A moving laterally (e.g., by moving laterally via at least one compression spring 123). According to some exemplary embodiments, the proximal end of the second linkage 122 may be open (e.g., U-shaped), although exemplary embodiments are not limited thereto. For example, the proximal end of the second linkage 122 may be closed (e.g., may be closed and define a slotted opening that receives the pin 149A). The at least one compression spring 123 is disposed on a spring mount (e.g., spring mount 123A in FIG. 4A ). The spring mount is located on the lower proximal sidewall of vertical support 147B of main body chassis 147, for example, spring mount 123A is located on proximal end piece 152 via a boss, although exemplary embodiments are not limited thereto.

[0089] According to some exemplary embodiments, there are at least two compression springs 123, one on the left side and one on the right side of the body chassis 147, respectively, although exemplary embodiments are not limited thereto. The compression springs 123 bias against and / or contact a lower proximal portion of the mouthpiece chassis 155. When the door 151 is opened, the mouthpiece chassis 155 moves laterally on the proximal side because the second linkage 122 and the second pivot 149A move laterally on the proximal side. This movement compresses the compression springs 123. Furthermore, the lateral movement of the mouthpiece chassis 155 on the proximal side disengages and / or moves the mouthpiece 160 and chimney 161 to an extended position because the mouthpiece 160 is connected to the mouthpiece chassis 155.

[0090] As shown in FIGS. 2C and 2D , the opposite end of the first linkage 121 is rotatably connected to a side (e.g., left side or right side) of the capsule receiving portion 175 (e.g., capsule receiving housing, capsule housing, capsule holder, etc.) via at least one pin 146B. The second linkage 122 is rotatably connected to a side of the door chassis 153 via at least one pin 149B. As described above, when the door 151 is opened and / or lifted, the capsule receiving portion 175 moves to the proximal end of the door 151 because of its connection to the first linkage 121. Furthermore, due to the movement of the door 151 and its connection to the door chassis 153, the second linkage 122 moves laterally proximally along the slot 148 (e.g., the door 151 pushes the second linkage 122 and the mouthpiece chassis 155 forward).

[0091] When a closing force is applied to the door 151 and / or the door 151 begins to close (e.g., when the door 151 rotates to the closed position), the previously compressed spring 123 converts its stored potential energy into kinetic energy, thereby assisting the mouthpiece chassis 155 in moving (e.g., being pushed) toward the distal end of the body chassis 147 (e.g., toward the closed position), thereby completely closing the door 151. This is because the first linkage 121 and the second linkage 122 are connected to the capsule receiving portion 175 and the door chassis 153, respectively.

[0092] According to some exemplary embodiments, when an adult operator applies a closing force to the door 151, the spring 123 may provide an auxiliary force to close the door 151. Furthermore, when the mouthpiece chassis 155 is pushed to the closed position by the biasing force of the spring 123 and / or by the closing force applied to the door 151 by the adult operator, the capsule receiver 175 moves and / or is pushed to the distal end (e.g., the closed position) of the door chassis 153 because the first linkage 121 is connected to the capsule receiver 175. Furthermore, when the mouthpiece chassis 155 moves to the closed position by the biasing force of the spring 123, the mouthpiece 160 also moves to the closed / retracted position and engages the inserted capsule 170 because the mouthpiece 160 is connected to the mouthpiece chassis 155 (discussed in more detail below). Additionally, the biasing force of spring 123 maintains mouthpiece 160, mouthpiece chassis 155, and door 151 in the closed / retracted position.

[0093] 2C-2E depict body chassis 147 as a single piece, example embodiments are not limited thereto. Body chassis may be formed using multiple pieces, such as body chassis 147 may include a left piece and a right piece, and / or a distal piece and a proximal piece.

[0094] According to some exemplary embodiments, the base frame of the body chassis 147 may be substantially rectangular, although exemplary embodiments are not limited thereto. For example, the base frame of the body chassis 147 may have a curved shape and / or other shape corresponding to the contour of the device body housing 101. The base frame of the body chassis 147 may include a recess corresponding to the position of the first recess 141 and may have dimensions substantially similar to the first recess 141.

[0095] As shown in FIG. 2E , according to at least one exemplary embodiment, when the door 151 is in an open position, the capsule receiver 175 moves to and / or is positioned at the proximal end of the door chassis 151. The capsule receiver 175 may be a housing formed of a high-temperature resistant plastic, such as polyetheretherketone (PEEK), liquid crystal polymer (LCP), acetal, or other material capable of withstanding high temperatures (e.g., approximately 80°C or higher), but exemplary embodiments are not limited thereto. Furthermore, according to some exemplary embodiments, a metal, such as aluminum or stainless steel, may be used. As shown in FIGS. 8A-8E and 9A-9C , the capsule receiver 175 has a substantially rectangular prism shape, including, but not limited to, a front surface, a rear surface, a left surface, a right surface, a proximal side, and a distal side. For example, the capsule receiver 175 may have another shape. The capsule receiving portion 175 includes an opening on a proximal side thereof that is configured to receive the capsule 170, thereby allowing the capsule 170 to be inserted into the capsule receiving portion 175. The proximal opening of the capsule receiving portion 175 may have the same or substantially the same shape as an end cap of the housing of the capsule 170, thereby facilitating proper alignment and / or fit of the capsule 170 and preventing objects other than the capsule from being inserted into the capsule receiving portion 175. However, the capsule receiving portion 175 is not limited to this, and other shapes of proximal openings may be used.

[0096] Additionally, capsule receiving portion 175 also includes an opening on its distal side. The distal opening of capsule receiving portion 175 can be smaller than the distal end of capsule 170, thereby holding capsule 170 in place and preventing it from descending into the internal cavity of device body housing 101 by one or more restricting members (e.g., 172A and 172B) protruding from the edge of capsule receiving portion 175. Restricting members 172A and 172B can be positioned in front of and behind the distal opening of capsule receiving portion 175, thereby holding capsule 170 within capsule receiving portion 175. Restricting members 172A and 172B, in turn, define an opening large enough to accommodate capsule connector 177. Capsule connector 177 enters the opening and connects, attaches, and / or mates with electrical contacts and / or airflow inlets located at the distal end of capsule 170. Furthermore, the suppression members 172A and 172B may have dimensions that reduce and / or minimize the surface area of ​​the capsule receiving portion and the holding member that contacts the capsule, thereby reducing and / or minimizing thermal contact between the capsule and the aerosol generating device 100. For example, according to one exemplary embodiment, the capsule has dimensions of approximately 12.4 mm x 6 mm, and each of the suppression members may have a length of approximately 4 mm and protrude from the edge of the capsule receiving portion by approximately 0.8 mm, although the exemplary embodiment is not limited thereto. For example, the suppression members 172A and 172B may be located on the left and right sides of the capsule receiving portion 175, and / or there may be more or fewer suppression members.

[0097] According to at least one exemplary embodiment, the device body housing 101 may further include, but is not limited to, a capsule detection switch 183 (e.g., a capsule detection sensor), a door detection switch 186 (e.g., a door detection sensor), and / or a haptic feedback motor 185. For example, one or more of the capsule detection switch 183, the door detection switch 186, and / or the haptic feedback motor 185 may be omitted. The capsule detection switch 183 may be a pressure switch, a contact switch, a sensor, or the like, disposed within the device body housing 101 to detect the presence or absence of the capsule 170 within the device body housing 101. For example, but not limited to, the capsule detection switch 183 may be turned on by and / or come into contact with the capsule 170 properly inserted into the capsule receiving portion 175 when the door 151 is moved to the closed position. In response to capsule detection switch 183 detecting the presence of capsule 170, capsule detection switch 183 transmits a first electrical signal (e.g., capsule detection signal, etc.) indicating the detection of a capsule to a control subsystem (e.g., 180 in FIG. 10 ). Furthermore, door detection switch 186 may be a pressure switch, a contact switch, a sensor, etc., disposed within device body housing 101 to detect whether door 151 and / or mouthpiece chassis 155 have moved to the closed and / or retracted positions. For example, door detection switch 186 may be turned on by and / or come into contact with mouthpiece chassis 155 when mouthpiece chassis 155 has moved to the closed and / or retracted positions, thereby indicating that door 151 is in the closed position. This is because first linkage 121 and second linkage 122 move. Exemplary embodiments are not limited to the above. For example, the door detection switch 186 may be positioned such that it is in direct contact with the door 151 when the door 151 is in the closed position.When the door detection switch 186 detects that the door 151 is in the closed position (and / or the mouthpiece chassis 155 is in the closed / retracted position, etc.), the door detection switch 186 sends a second electrical signal (e.g., a door detection signal, etc.) to the control subsystem 180 indicating that the door 151 is closed.

[0098] According to some exemplary embodiments, in response to receiving a first electrical signal and a second electrical signal from capsule detection switch 183 and door detection switch 186, respectively, control subsystem (e.g., 180 in FIG. 10 ) allows current to flow from battery 182 to capsule 170. Further, in response to the control subsystem (e.g., processing circuitry, control circuitry, etc.) not receiving the first electrical signal from capsule detection switch 183 and / or not receiving the second electrical signal from door detection switch 186, control subsystem 180 disables and / or inhibits current from flowing from battery 182 to capsule receiver 175.

[0099] However, example embodiments are not limited in this regard. Capsule detection switch 183 and / or door detection switch 186 may be omitted and / or not used by the control subsystem to control the flow of current from battery 182 to capsule receiver 175. Furthermore, according to some example embodiments, the first electrical signal and / or the second electrical signal may be a binary signal, with a first value indicating that the capsule and / or door has been detected as closed and a second value indicating that the capsule and / or door has not been detected as closed (e.g., no closure detection), although example embodiments are not limited in this regard.

[0100] According to some exemplary embodiments, the control subsystem may further include a haptic motor 185 (e.g., a haptic feedback motor, etc.) to provide a first haptic response (e.g., a vibration having a first desired intensity, a first desired frequency, and / or a first desired interval, etc.) in response to receiving a first electrical signal from the capsule detection switch 183, indicating that the capsule 170 has been properly installed in the aerosol generation device 100. The control subsystem may further control the haptic motor 185 to provide a second haptic response (e.g., a vibration having a second desired intensity, a second desired frequency, and / or a second desired interval, etc.) in response to receiving a second electrical signal from the capsule detection switch 183, indicating that the capsule 170 has not been properly installed in the aerosol generation device 100. According to some exemplary embodiments, the control subsystem further controls the display panel 107 / 107A to display status information regarding the capsule 170, such as in response to receiving the first and / or second electrical signals from the capsule detection switch 183. Furthermore, according to some exemplary embodiments, the aerosol generating device 100 further includes a speaker, and the control subsystem may further control the speaker to provide auditory feedback (e.g., tones, beeps, music, recorded messages, etc.) to the adult operator regarding the insertion and / or removal of the capsule 170 from the aerosol generating device 100, the status of the plant material contained within the capsule 170, battery status information, etc.

[0101] Although the figures show the door assembly and mouthpiece assembly elements as being located at the proximal portion 150 of the aerosol generating device 100, example embodiments are not limited thereto. For example, the door assembly may be located at the distal portion 105 of the aerosol generating device 100, etc. Furthermore, although the figures show the door 151 as being located at the front of the aerosol generating device 100, example embodiments are not limited thereto. The door 151 may be located on other sides of the aerosol generating device 100.

[0102] 3A-3F illustrate various views of a door assembly according to at least one exemplary embodiment.

[0103] Reference is made to Figures 3A through 3D. Figure 3A is an exploded view of a door assembly according to at least one exemplary embodiment.

Figure 3D is a bottom perspective view of the internal elements of the door assembly in a closed position.

[0104] According to at least one exemplary embodiment, the door assembly 1100 may include, but is not limited to, a door 151, a door chassis 153, at least one cam-activated restraining element 176, a capsule receiver 175, and a capsule connector 177. Each of the door 151, the door chassis 153, the at least one cam-activated restraining element 176, the capsule receiver 175, and the capsule connector 177 may be symmetrical about a longitudinal axis, but is not limited to such.

[0105] According to at least one exemplary embodiment, the door 151 may further include, but is not limited to, at least one cam 156 and a hinge 120. The cam 156 and the cam-activated restraining element 176 are described in more detail below. The door chassis 153 may be attached to the inside of the door 151 via one or more clips 151A attached to clip slots 151B, although exemplary embodiments are not limited thereto. The door chassis 153 may be screwed, welded, and / or engaged to the inside of the door 151. The door chassis 153 may define a substantially planar rectangular frame, may include a vertical opening 153A within the planar rectangular frame, and may further include a pair of side wings 153B. According to at least one exemplary embodiment, the door chassis 153 is open on a proximal side, a distal side, and a rear side. Additionally, the door chassis 153 may further include at least one vertical boss 190A to mate with a boss 190 of the capsule connector 177. This allows the capsule connector 177 to be attached and / or secured to the door chassis 153, although the example embodiment is not limited thereto. Other types of engagement may also be used. Additionally, the door chassis 153 includes a pair of openings 153C (e.g., hinge points, etc.) that connect and / or mate with pins 149B located at the distal end of the second linkage 122, allowing the second linkage 122 to rotate about the openings 153C. The door chassis 153 further includes a pair of rails 157 (e.g., tracks, sliders, guide rails, etc.) on either side of the door chassis 153 frame. When the capsule receiving portion 175 is inserted into the opening 153A from above (e.g., lowered), the rails 157 contact a pair of laterally protruding edges 158 on the front surface of the capsule receiving portion 175, thereby allowing the capsule receiving portion 175 to move (e.g., slide, travel, etc.) from the proximal end to the distal end of the opening 153A in the door chassis 153 when a longitudinal force is applied.

[0106] Furthermore, the capsule receiving portion 175 is a substantially cubic-shaped frame configured to hold the capsule 170. The capsule receiving portion 175 includes a proximal side defining a proximal opening 170A for receiving the capsule 170, the proximal opening 170A having the same dimensions as and / or larger dimensions than the capsule 170 and having substantially the same shape as the capsule 170. For example, the proximal opening and internal cavity of the capsule receiving portion 175 may extend longitudinally toward the distal side of the capsule receiving portion 175 and have dimensions that are approximately 0.1 mm larger than the dimensions of the outer housing of the capsule 170. This is to form an air gap between the capsule receiving portion 175 and the outer housing of the capsule 170, although exemplary embodiments are not limited to the above. Furthermore, a pair of longitudinally extending inner rails 176E may be defined on the inner wall (e.g., cavity wall) of the capsule receiving portion 175, and the space adjacent to each inner rail may be recessed, notched, or the like. When the capsule 170 is not connected to the capsule connector 177 (e.g., while the door assembly 1100 is moving to the closed position), the inner rail 176E may further contact and / or guide the inserted capsule 170 toward the capsule connector 177, and may additionally increase the air gap and / or air insulation around the capsule 170 on either side of the inner rail 176E. However, example embodiments are not limited in this respect. According to some example embodiments, the air gap may be omitted or may be greater or less than 0.1 mm. The air gap is described in more detail below.

[0107] Further, according to some exemplary embodiments, capsule receiver 175 may define front channel 176D and rear opening 170B. At least one cam-activated restraining element 176 may be positioned in front channel 176D. The body of cam-activated restraining element 176 may have a substantially planar shape and include, but is not limited to, a hinge 176A disposed at a distal end of cam-activated restraining element 176, a hook-shaped (or L-shaped) contact element 176B disposed at a proximal end of cam-activated restraining element 176, and a protrusion and / or bump 176C disposed on a front surface of cam-activated restraining element 176. Cam-activated restraining element 176 may have various designs or configurations.

[0108] According to at least one example embodiment, hinge 176A of cam-activated restraining element 176 can mate with hinge opening 176B of capsule receiver 175. Additionally, front channel 176D can further include a rear opening into internal cavity 170A of capsule receiver 175, thereby allowing contact element 176B of cam-activated restraining element 176 to descend into internal cavity 170A and / or contact a capsule installed in internal cavity 170A of capsule receiver 175. Furthermore, protrusion 176C can be configured to contact cam 156 on the rear surface (e.g., inner surface) of door 151 when capsule receiver 175 slides downward along rail 157 of door chassis 153, thereby forcing cam-activated restraining element 176 to contact the surface of installed capsule 170, etc.

[0109] Additionally, the capsule receiver 175 includes at least one hinge point 146B (e.g., a hinge pin, etc.) for attachment to the distal end of the at least one first linkage 121. Accordingly, the capsule receiver 175 moves toward the capsule connector 177 when the door assembly 1100 is moved to the closed position, or moves away from the capsule connector 177 when the door assembly 1110 is moved to the open position, etc. The capsule receiver 175 further defines a rear opening 170B. A capsule detection switch (e.g., capsule detection switch 183) disposed on a PCB on the rear inner surface of the device body housing 101 may fit within the rear opening 170B of the capsule receiver 175 when the door assembly 1100 is rotated to the closed position and may contact and / or detect the capsule 170 installed in the capsule receiver 175 when the capsule receiver 175 is in the closed position, although example embodiments are not limited thereto.

[0110] The door assembly 1100 may further include, but is not limited to, a capsule connector 177, which provides air and electrical connections to a capsule installed in the capsule receiving portion 175. According to some exemplary embodiments, when the capsule 170 is in the capsule receiving portion 175 and the capsule receiving portion 175 moves to the distal end of the door chassis 153 in response to the door 151 being closed (e.g., the door assembly being in the closed position), the capsule 170 is connected to both the electrical subsystem and the airflow subsystem (e.g., the air hose 116, etc.) of the aerosol generating device 100. Or, in other words, the capsule 170 automatically positions, steers, and / or guides itself to the appropriate position, thereby ensuring that a robust electrical connection and fluid-tight seal is achieved between the capsule 170 and the aerosol generating device 100. The electrical subsystem and the airflow subsystem are described in more detail below.

[0111] The capsule connector 177 may be fixedly attached (e.g., screwed, welded, engaged by a boss) to the door chassis 153 and / or door 151. As shown in FIGS. 3A and 3D , the capsule connector 177 is embossed via a boss 190 to a boss 190A located on the interior surface of the door. The capsule connector 177 further includes a capsule connector sealing element 178 that aligns with the distal end of the capsule 170 to form an airtight and / or substantially airtight seal therewith. The capsule connector 177 is described in more detail below.

[0112] 3E and 3F, in accordance with at least one exemplary embodiment, a cross-sectional view of a cam-activated restraining element and a door assembly in a closed position and a cross-sectional view of a cam-activated restraining element and a door assembly in an open position.

[0113] According to some exemplary embodiments, the capsule receiver 175 further includes at least one cam-activated restraining element 176 (e.g., a restraining element, an anti-bounce cam, a finger element, etc.) such that the capsule receiver 175 frictionally engages with a capsule 170 inserted into an opening of the capsule receiver 175 to prevent the capsule 170 from being accidentally dislodged and / or separated from the capsule receiver 175 while the door 151 moves from the open position to the closed position and / or while the door 151 moves from the closed position to the open position. Additionally, the at least one cam-activated restraining element 176 prevents the capsule 170 inserted into the opening of the capsule receiver 175 from being accidentally dislodged, separated, and / or separated from the capsule connector 177 when the door 151 is in the closed position. As shown in FIGS. 3A, 3E, and 3F, the cam-activated restraining element 176 includes a hinge 176A at the distal end of the capsule receiving portion 175 and a hook-shaped contact element 176B (e.g., a "finger" piece, a T-shaped piece, etc.) at the proximal end of the capsule receiving portion 175, but this is not limiting the exemplary embodiment. The contact element may have a different shape. The door 151 may include at least one cam 156 that engages, contacts, and / or restrains movement of the top surface of the capsule 170 while the door 151 is moving to the closed position. This reduces and / or prevents the capsule 170 from disengaging and / or separating from the capsule connector 177 when the door 151 is in the closed position. More specifically, the cam 156 has a beveled proximal edge (e.g., a leading edge). While the cam-activated restraining element 176 and capsule receiving portion 175 move toward the distal end of the door 151, the proximal edge contacts a protruding element 176C (e.g., a bump) located on the front surface of the cam-activated restraining element 176.

[0114] 3E , while the cam-activated restraining element 176 is in contact with the cam 156, the contact element of the cam-activated restraining element 176 is pushed downward (e.g., toward the capsule, toward the interior space of the device body housing, etc.). According to an exemplary embodiment, the cam-activated restraining element 176 engages with the capsule 170, thereby holding the capsule 170 in place. Furthermore, according to an exemplary embodiment, the cam-activated restraining element 176 engages with the capsule 170 and prevents / holds the capsule 170 in place even if the orientation of the aerosol generating device 100 is changed (e.g., if the aerosol generating device 100 is held upside down, backwards, or vertically).

[0115] Furthermore, when the cam-activated restraining element 176 engages the cam 156, the contact element 176B restrains the capsule 170 from displacing, moving, and / or bouncing when the door 151 is closed using friction between the contact element 176B and the surface of the capsule 170. Furthermore, when the door 151 is in the fully open position and the cam-activated restraining element 176 and capsule receiver 175 are in the open position, the cam-activated restraining element 176 loses contact with the cam 156 due to a recess in the door 151. This causes the contact element 176B of the cam-activated restraining element 176 to disengage from and / or move away from the surface of the capsule 170. As a result, an adult operator can remove the capsule 170 from the capsule receiver 175.

[0116] 3F, the proximal opening of the capsule receiving portion 175 may have dimensions larger than the dimensions of the capsule 170. This is to provide an air gap 174 between the capsule 170 and the inner wall of the capsule receiving portion 175 on at least two sides of the capsule 170 (e.g., both sides of the capsule 170), but the exemplary embodiment is not limited to this. For example, the proximal opening may be approximately 12.6 mm by 6.2 mm at its widest point, and there may be an air gap 174 of approximately 0.1 mm between the outer diameter of the capsule and the proximal opening of the capsule receiving portion 175, but the exemplary embodiment is not limited to this. The air gap provides thermal insulation between the heated capsule 170 and the device body housing 101, thereby reducing the temperature of the device body housing 101 and reducing / minimizing thermal discomfort experienced by an adult operator during operation of the aerosol generating device 100.

[0117] According to some exemplary embodiments, the capsule receiving portion 175 may further include one or more pairs of inner rails 176E defined on one or more inner surfaces of the capsule receiving portion 175 to guide the capsule 170 into the internal cavity of the capsule receiving portion 175 when the capsule 170 is not connected to the capsule connector 177 (e.g., the capsule 170 may contact the inner rails 176E due to gravity, misalignment, etc.). However, the dimensions of the pairs of inner rails 176E may be such that when the capsule 170 is mated and / or connected with the capsule connector 177, the inner rails 176E do not protrude into the internal cavity of the capsule receiving portion 175, thereby establishing and / or maintaining an air gap 174 around the capsule 170. In other words, while the door 151 is in a fully closed position (and the capsule receiving portion 175 is at the distal end (e.g., closed position) of the door chassis 153), the capsule 170 does not contact the inner rail 176E of the capsule receiving portion 175, but when the door 151 is moving and / or in an open position, for example, when the capsule 170 is disengaged from the capsule connector 177, the capsule 170 may contact the inner rail 176E of the capsule receiving portion 175.

[0023] Figures 4A through 4F show various views of a mouthpiece assembly according to some exemplary embodiments. More specifically, Figure 4A is an exploded view of a mouthpiece assembly according to at least one exemplary embodiment. Figure 4B shows the mouthpiece assembly of Figure 4A in an open position. Figure 4C shows a second view of the mouthpiece assembly of Figure 4B in the open position without the proximal end piece. Figure 4D shows the mouthpiece assembly of Figure 4A in a closed position. Figure 4E shows a second view of the mouthpiece assembly of Figure 4D in the closed position without the proximal end piece. Figure 4F shows the mouthpiece assembly of Figure 4D in a closed position aligned with the capsule and capsule connector, according to some exemplary embodiments.

[0119] According to at least one exemplary embodiment, the mouthpiece assembly 1200 may include a removable mouthpiece 160, a chimney 161 connected to (e.g., integrated with) the mouthpiece 160, and a mouthpiece chassis 155, although exemplary embodiments are not limited thereto. For example, the chimney 161 may be detachable from the mouthpiece 160. As shown in FIGS. 4A to 4D , various elements of the mouthpiece assembly 1200 are substantially symmetrical about the longitudinal axis, although exemplary embodiments are not limited thereto. The mouthpiece assembly 1200 may be installed within the interior space of the device body housing 101 of the aerosol generation device 100. More specifically, the proximal end piece 152 and / or the spring mount 123A may be attached to a stationary internal frame (e.g., the body chassis 147) of the device body housing 101 via clips, such as clip 152A, although exemplary embodiments are not limited thereto. Other equivalent attachment methods may also be used.

[0120] Furthermore, mouthpiece chassis 155 may be, but is not limited to, movably (e.g., slidably, etc.) attached to a stationary body chassis (e.g., body chassis 147) of device body housing 101. Mouthpiece chassis 155 may be movably (e.g., slidably, etc.) attached to rails (e.g., slots 148) of the stationary body chassis using one or more pins 149A, thereby allowing mouthpiece chassis 155 to move longitudinally along the inner surface of device body housing 101. Furthermore, one or more pins 149A may be further rotatably and / or slidably attached and / or connected to at least one linkage (e.g., second linkage 122). The at least one linkage applies a force to mouthpiece chassis 155 to move laterally within slot 148 of body chassis 147 via pin 149A. The mouthpiece chassis 155 may be substantially L-shaped when viewed from the side, with the vertical portion of the mouthpiece chassis 155 further defining an opening 155A configured to receive the chimney 161 of the mouthpiece 160. The horizontal portion of the mouthpiece chassis 155 may define a rear opening 155B. When the capsule receiving portion 175 and the mouthpiece chassis 155 are in the closed position, the rear opening 155B aligns with the rear opening 170B of the capsule receiving portion 175, thereby allowing a sensor, such as a capsule detection switch 183, to access the capsule 170 installed in the capsule receiving portion 175, and so on.

[0121] Furthermore, the mouthpiece chassis 155 may include at least one bayonet enclosure 163. The bayonet enclosure 163 receives at least one bayonet connector 162 of the chimney 161 and locks the mouthpiece 160 to the mouthpiece chassis 155. For example, there may be two or more bayonet connectors and enclosures, but example embodiments are not limited thereto. At least one compression spring 123 may be mounted to the U-shaped spring frame 123A, and the spring frame 123A may be attached to the proximal end piece 152 (e.g., via screws, welding, etc.) and / or the main body chassis (e.g., the main body chassis 147) and disposed between the proximal end piece 152 and the mouthpiece chassis 155, but example embodiments are not limited thereto. As shown in FIG. 4A , two or more compression springs 123 may be mounted to two or more arms of the spring frame 123A, but example embodiments are not limited thereto. Compression spring 123 may be biased against mouthpiece chassis 155, such that mouthpiece chassis 155 compresses compression spring 123 as it moves longitudinally proximally. Furthermore, when compression spring 123 is released, the compressed compression spring 123 exerts a distal longitudinal biasing force on mouthpiece chassis 155, thereby causing and / or assisting in the distal longitudinal movement of mouthpiece chassis 155. Movement of mouthpiece chassis 155 is described in more detail below with reference to Figures 5A-5C and 6A-6C.

[0122] The removable mouthpiece 160 may include, but is not limited to, an elongated chimney 161 defining at least one aerosol outlet 165, at least one bayonet connector 162, and a sealing element 164. The chimney 161 is inserted into the opening 154 in the proximal end piece 152 and connected (e.g., attached, secured, etc.) to the mouthpiece chassis 155 using the bayonet connector 162. As described above, the mouthpiece chassis 155 may move longitudinally (e.g., toward the proximal and distal ends of the aerosol generating device) a desired distance, such as that corresponding to the length of the slot 148 in the main body chassis 147. When the mouthpiece 160 is attached to the mouthpiece chassis 155 and the mouthpiece chassis 155 moves longitudinally either proximally or distally, the mouthpiece 160 also moves longitudinally proximally and distally along with the mouthpiece chassis 155. Further, as shown in Figure 4D, when mouthpiece 160 is moved to the closed position, the mouthpiece engages detents 167 located on the upper outer surface of proximal end piece 152. Further, as shown in Figure 4F, when mouthpiece assembly 1200 and door assembly 1100 are moved together to the closed position, mouthpiece chassis 155 and capsule receiver 175 are aligned such that mouthpiece chimney 161 and mouthpiece sealing element 164 are aligned with the proximal end of capsule 170 to seal against the proximal end, and such that the distal end of capsule 170 is aligned with capsule connector sealing element 178 of capsule connector 177 to seal against the capsule connector sealing element 178, etc.

[0123] 5A-5C illustrate the movement of a door assembly and a mouthpiece assembly as the door of an aerosol generating device according to at least one exemplary embodiment moves from an initial open state to a final closed state. More specifically, FIG. 5A illustrates the door assembly and the mouthpiece assembly in an initial open state. FIG. 5B illustrates the door assembly and the mouthpiece assembly in an intermediate state. FIG. 5C illustrates the door assembly and the mouthpiece assembly in a final closed state. FIGS. 5A-5C are simplified versions of the door assembly and the mouthpiece assembly, showing only the door chassis 153, the mouthpiece 160, and portions of the mouthpiece chassis 155, and omitting the body chassis 147, the capsule 170, the capsule connector 177, etc., for example, to more clearly illustrate the operation of various elements of the door assembly (e.g., door assembly 1100) and the mouthpiece assembly (e.g., mouthpiece assembly 1200) according to at least one exemplary embodiment.

[0124] According to at least one exemplary embodiment, door assembly 1100 (e.g., door 151, etc.) may be assumed to start in an initial open state. An outward, downward force F1 may be applied by an adult operator to door 151 and / or door assembly 1100, causing door 151 to close. Force F1 causes door 151 to rotate (e.g., pivot, etc.) in a downward direction F2 about hinge point 120. Movable capsule receiver 175 is rotatably attached to at least one first linkage 121 at pivot point 146B (e.g., pin, etc.). In turn, first linkage 121 is rotatably attached to stationary body chassis 147 at pivot point 146A. As shown in FIG. 5B , as door 151 begins to rotate in the downward direction F2, first linkage 121 also rotates (e.g., pivots) in a downward direction F3 about pivot point 146A. This causes the movable capsule receiver 175 to move along direction F4 to the distal end of the door 151 / door chassis 153 and toward the capsule connector 177 (not shown in FIGS. 5A-5C ), causing the capsule installed in the capsule receiver 175 to connect and / or engage with the capsule connector 177.

[0125] At the same time, rotation of door 151 downward (e.g., F2) causes at least one second linkage 122, which is rotatably attached to pivot point 149B of door chassis 153, to move downward F5. Due to the length of second linkage 122 according to some exemplary embodiments, when door 151 rotates toward the closed position, the distal end of second linkage 122 (e.g., the end attached to pivot point 149B, which is attached to mouthpiece chassis 155) moves to a height that is equal to or lower than the opposite end of second linkage 122 (e.g., the end attached to pivot point 149A). This releases second linkage 122 from the "over-center" position, thereby releasing compression spring 123. The released compression spring 123 releases its stored potential energy, causing the compression spring 123 to exert a biasing and / or auxiliary force that urges the movable mouthpiece chassis 155 proximally along the slot 148 (not shown) in the body chassis 147, e.g., in the direction F6, and further urges the connected mouthpiece 160 into a closed position (e.g., an attached position, a connected position, etc.) adjacent the proximal end piece 152. This causes the mouthpiece 160 to engage and / or connect with a detent 167 located on the outer surface of the proximal end piece 152.

[0126] 6A-6C illustrate the movement of a door assembly and a mouthpiece assembly as the door of an aerosol generating device according to at least one exemplary embodiment moves from an initial closed state to a final open state. More specifically, FIG. 6A illustrates the door assembly and the mouthpiece assembly in an initial closed state. FIG. 6B illustrates the door assembly and the mouthpiece assembly in an intermediate state. FIG. 6C illustrates the door assembly and the mouthpiece assembly in a final open state. Like FIGS. 5A-5C, FIGS. 6A-6C are simplified versions of the door assembly and the mouthpiece assembly, omitting only the door chassis 153, the mouthpiece 160, and portions of the mouthpiece chassis 155, e.g., the body chassis 147, the capsule 170, the capsule connector 177, etc., to more clearly illustrate the operation of various elements of the door assembly (e.g., door assembly 1100) and the mouthpiece assembly (e.g., mouthpiece assembly 1200) according to at least one exemplary embodiment.

[0127] According to at least one example embodiment, the door assembly 1100 (e.g., door 151) may start in an initial closed state. When an adult operator applies an outward and upward (e.g., lifting) force F A may be applied to the door assembly 1100 / door 151. An upward force F A This causes the door assembly 1100 / door 151 to rotate upward F about a pivot point (e.g., hinge) 120. B Rotate upwards F B 146A, the at least one first linkage 121 rotates upward F about the pivot point 146A. C Rotate to. Rotation F B and upward F C This combination causes the movable capsule receiver 175 to begin to move toward the distal end of the door 151 and door chassis 153 because the first linkage 121 is attached to the capsule receiver 175. This movement causes the capsule 170 (not shown) installed in the capsule receiver 175 to disengage from the capsule connector 177 (not shown).

[0128] At the same time, an upward force F of the door assembly 1100 / door 151 A and rotational translation F B As a result, the door chassis 153 moves upward F E Rotate upwards. E 149B, the distal end of the second linkage 122 also moves upward because it is connected to the door chassis 153 at the pivot point 149B. As a result of this movement, the end of the second linkage 122 opposite the distal end moves in the longitudinal direction F transversely along the slot 148 in the main chassis 147 toward the proximal end of the aerosol generating device 100. F This causes the mouthpiece chassis 155 to move in the horizontal longitudinal direction F F 6C, the spring 123 is moved in the longitudinal direction F F The movement of F also disengages the mouthpiece 160 connected to the mouthpiece chassis 155 from the detent 167 and moves F to the extended / open position. F 6C, when door assembly 1100 and mouthpiece assembly 1200 are in the open position, second linkage 122 acts as an over-center mechanism, holding second linkage 122 and door assembly 1100 in a parked position (e.g., the open position).

[0129] 7A through 7F show various views of mouthpieces according to some exemplary embodiments. FIG. 7A is a rear-front perspective view of a first set of mouthpiece designs according to at least one exemplary embodiment. FIG. 7B is a top view of a first design of the first set of mouthpieces of FIG. 7A. FIG. 7C is a top view of a second design of the first set of mouthpieces of FIG. 7A. FIG. 7D is a first rear-front perspective view of a second set of mouthpiece designs according to at least one exemplary embodiment. FIG. 7E is a second rear-front perspective view of the second set of mouthpiece designs according to at least one exemplary embodiment. FIG. 7F is a top view of the second set of mouthpieces of FIGS. 7D and 7E.

[0130] According to at least one exemplary embodiment, the chimney 161 of the mouthpiece 160 further includes a bayonet connector 162 (e.g., male engaging members) that may be connected to and / or attached to a bayonet enclosure 163 (e.g., female engaging members) of the mouthpiece chassis 155 and / or the body chassis 147. This allows for removal of the mouthpiece 160 and / or replacement of the mouthpiece 160. For example, the chimney 161 is inserted into a mouthpiece opening at the proximal end of the device body housing 101 and rotated to lock the bayonet connector 162 into the bayonet enclosure 163. However, exemplary embodiments are not limited in this respect. For example, the mouthpiece 160 may be attached using, without limitation, a snug fit, a detent, a clamp, a threaded connector, a slide fit, a sleeve fit, an alignment fit, a threaded connector, a magnetic, a clasp, or any type of connection, and / or combinations thereof. Additionally, a haptic feedback motor, such as a sound (e.g., a click), a signal, or the like, may be provided in response to bayonet connector 162 being locked to and / or unlocked from bayonet enclosure 163, thereby informing the adult operator that mouthpiece 160 has been properly installed to and / or uninstalled from mouthpiece chassis 155. Furthermore, because mouthpiece 160 is removable from device body housing 101, an adult operator may clean mouthpiece 160 and chimney 161, as well as replace mouthpiece 160 when desired, and / or use different mouthpiece designs and / or configurations with device body housing 101.

[0131] The distal end of the chimney 161 further includes an integral sealing element 164 and / or an integral sealing adapter configured to form a sealed connection with an outlet included in the proximal end of the capsule 170, thereby facilitating the flow of generated aerosol from the capsule 170 to at least one aerosol outlet of the mouthpiece 160. The integral sealing element 164 may be formed from, but is not limited to, silicone, other food-grade rubber, and / or equivalent materials. For example, but is not limited to, the integral sealing element 164 may be formed from any material that is resistant to high temperatures (e.g., >80°C), has a food contact rating, and is capable of forming an airtight seal between the chimney 161 and the capsule 170.

[0132] 7A-7C illustrate a first set of exemplary mouthpieces according to at least one exemplary embodiment. As shown in FIGS. 7A and 7B, the proximal end of the mouthpiece 160 has a prismatic shape, with the width of the oval-shaped proximal end of the mouthpiece 160 being narrower than the width of the oval-shaped distal end of the mouthpiece 160, and the proximal end having a single aerosol outlet 165B, although exemplary embodiments are not limited in this respect. Furthermore, as shown in FIG. 7C, the prismatic mouthpiece 160 of FIG. 7A may have a proximal end with a different shape; in this example, the mouthpiece 160 has multiple (e.g., four) aerosol outlets 165B defined by a cross-shaped diffuser element 165A. However, exemplary embodiments are not limited in this respect. A different number of aerosol outlets 165 and diffuser elements 165A may have different shapes and / or designs.

[0133] 7D-7F illustrate another mouthpiece 160 as a second set of exemplary mouthpieces according to another exemplary embodiment. The alternative mouthpiece 160 has a cylindrical shape, with the proximal end of the cylindrical body being generally circular and the oval-shaped distal end being wider. Furthermore, as shown in FIG. 7F, the proximal end of the mouthpiece 160 includes, but is not limited to, multiple aerosol outlets 165. For example, the proximal end of the mouthpiece 160 may include a greater or lesser number of aerosol outlets 165. Furthermore, as shown in FIGS. 7A, 7D, and 7E, the distal end may further include a lip 166 that contacts the proximal end piece 152 of the device body housing 101. When rim 166 of mouthpiece 160 is securely fastened to and / or pressed against detents 167 included on a surface of proximal end piece 152 of device body housing 101, for example, when door 151 is properly closed and mouthpiece 160 is in a retracted position, rim 166 provides haptic feedback, such as a click, pop, and / or snap, indicating that mouthpiece 160 has been properly retracted. Additionally, when mouthpiece 160 is pressed away from proximal end piece 152 while door 151 is open, rim 166 separates from detents 167 of proximal end piece 152, again providing haptic feedback (such as a click, pop, and / or snap) indicating that mouthpiece 160 has separated from device body housing 101.

[0134] As shown in Figures 7D and 7E, the length of the cylindrical mouthpiece 160 can be any desired length, but exemplary embodiments are not limited thereto.

[0135]

[0023] Figures 8A-8E show various views of a door assembly, capsule receiver, and capsule connector according to some exemplary embodiments. Figure 8A is a rear view of the door assembly according to at least one exemplary embodiment. Figure 8B is a top and front perspective view of the capsule connector of Figure 8A. Figure 8C is a bottom and front perspective view of the capsule connector of Figure 8A. Figures 8D and 8E show examples of first and second sets of electrical contact structures of the capsule connector according to some exemplary embodiments.

[0136] According to at least one exemplary embodiment, the door chassis 153 further includes a capsule connector 177 at a distal portion of the door chassis 153, i.e., at an end of the door chassis 153 remote from and facing the capsule receiving portion 175. When the door 151 (e.g., the door assembly 1100) is moved to the closed position, the capsule receiving portion 175 moves such that the capsule connector 177 is inserted into a distal opening of the capsule receiving portion 175 to form a connection and / or seal between the capsule 170 and the capsule connector 177. More specifically, the capsule connector 177 includes at least one capsule connector sealing element 178, at least one capsule connector air inlet 179, at least one vertical electrical contact 173, at least one horizontal electrical contact 171, etc. The capsule connector 177 may be fixedly mounted and / or attached to the rear (e.g., inside) of the door chassis 153, for example, using a boss 190 that fits over a boss 190A of the door chassis 153, but this is not a limitation of the example embodiment. For example, but not limited to, the capsule connector 177 may be secured to the door chassis 153 by screws, welding, etc. When the door 151 is moved to the open position, the capsule receiver 175 is moved with the door assembly such that the connection and / or seal between the capsule connector 177 and the capsule 170 is broken.

[0137] According to at least one exemplary embodiment, at least one capsule connector sealing element 178 is a silicone sealing element and / or other compressible sealing material disposed on a proximal side of capsule connector 177 that defines an air channel between capsule connector air inlet 179 and one or more capsule air inlets disposed at the distal end of capsule 170. Capsule connector 177 may further include at least one horizontal electrical contact 171. Capsule connector sealing element 178 further includes an angled flat surface that guides recess 221 of capsule 170 and mates with recess 211 to form an airtight seal for air fluid communication between capsule connector 177 and capsule 170.

[0138] For example, as shown in FIG. 8B , the capsule connector 177 includes a plurality of horizontal electrical contacts 171 on a proximal side thereof, with a first set of horizontal electrical contacts contacting a first side of the capsule connector sealing element 178 and a second set of horizontal electrical contacts contacting a second side of the capsule connector sealing element 178, although the exemplary embodiment is not limited thereto. The horizontal electrical contacts may be arranged in other patterns and / or locations. When the door 151 is in the closed position, the horizontal electrical contacts 171 contact electrical contacts on the capsule 170, thereby establishing an electrical connection between the capsule connector 177 and the capsule 170. More specifically, the horizontal electrical contacts 171 may establish an electrical circuit between at least one heater 230 and the battery 182 of the capsule 170. According to at least one embodiment, the horizontal electrical contacts 171 and / or the capsule connector sealing element 178 extend beyond the proximal side of the capsule connector 177. As a result, when the capsule 170 moves to the closed position, the horizontal electrical contact 171 and / or the capsule connector sealing element 178 are compressed, ensuring an improved electrical and / or fluid connection between the capsule connector 177 and the capsule 170.

[0139] 2E and 8B, capsule connector 177 may further include at least one vertical electrical contact 173. As shown in FIG. 8B, at least one vertical electrical contact 173 may be a plurality of vertical electrical contacts 173 extending downwardly from capsule connector 177. According to at least one exemplary embodiment, vertical electrical contact 173 may be permanently electrically connected (e.g., soldered, etc.) to electrical wire 184, may be integral with electrical wire 184, and / or may be an extension of electrical wire 184, although exemplary embodiments are not limited thereto.

[0140] According to another exemplary embodiment, as shown in Figure 2B, the vertical electrical contact 173 is not permanently electrically connected to the electrical wire 184. Instead, when the door 151 is in the closed position, the vertical electrical contact 173 contacts the electrical wire 184 in the device body housing 101, thereby establishing an electrical connection between the capsule connector 177 and the electrical subsystem of the aerosol generating device 100.

[0141] In both exemplary embodiments, when vertical electrical contact 173 is connected to electrical wire 184, electrical wire 184 can provide power (e.g., current) from rechargeable battery 182 to capsule connector 177, which can then provide power to capsule 170 via horizontal electrical contact 171. When door 151 is in the open position (and / or when door 151 is not in the closed position), capsule connector 177 moves away from the closed position, thereby disconnecting both the connection between horizontal electrical contact 171 and capsule 170 and the connection between vertical electrical contact 173 and electrical wire 184.

[0142] While some figures, such as FIG. 2B , depict the electrical wire 184 as multiple coils, exemplary embodiments are not limited to this. The electrical wire may be configured in any manner. According to at least one exemplary embodiment, the electrical wire 184 includes at least one coil, a flexible electrical wire, or the like. For example, two or more coils of the electrical wire 184 may be spaced apart at a desired distance (e.g., the width of the vertical electrical contacts 173) and positioned so that the two or more coils of the electrical wire 184 contact both sides of one or more vertical electrical contacts 173, i.e., provide multiple points of contact with the one or more vertical electrical contacts 173. This is to ensure a stable electrical connection between the electrical wire 184 and the vertical electrical contacts 173 and to reduce the likelihood that the vertical electrical contacts 173 will be separated from the electrical wire 184 due to vibration, shock, collision, or the like of the aerosol generating device 100.

[0143] 8D and 8E. FIG. 8D illustrates a first design of electrical contacts for the capsule connector 177 according to some exemplary embodiments, the design including linear vertical contacts 173. FIG. 8E illustrates a second design of electrical contacts for the capsule connector 177 according to some exemplary embodiments, the design including offset vertical contacts 173. As shown in FIGS. 8D and 8E, the horizontal electrical contacts 171 and the vertical electrical contacts 173 are integrated into a single electrical wire structure, but exemplary embodiments are not limited thereto. Other designs, configurations, and / or structures may be used for the horizontal electrical contacts 171 and the vertical electrical contacts 173. As shown in FIGS. 8D and 8E, the horizontal electrical contact 171 may include a first straight portion 171 and a second spring-like and / or serpentine portion 171A. In response to the capsule receiving portion 175 moving to the closed position and connecting to the capsule connector 177, the first portion 171 of the horizontal electrical contact contacts the opposing electrical contacts at the distal end of the capsule 170. Furthermore, the second portion 171A of the horizontal electrical contact allows the horizontal electrical contact 171 to compress, thereby improving the electrical connection between the horizontal electrical contact 171 and the opposing electrical contact of the capsule 170. In addition, the likelihood of the electrical connection being broken due to vibrations, bumps, shocks, etc., experienced by the aerosol generating device 100 is reduced.

[0144] 8C , when the door 151 is in the closed position, the capsule connector air inlet 179 is configured to connect, mate, attach, etc. to at least one air hose 116 of the device body housing 101. When an inhalation event and / or negative pressure is applied to the mouthpiece 160 with the door 151 in the closed position and external air flowing into the air inlet of the capsule 170, the at least one capsule connector air inlet 179 receives external air from the body housing air inlet 113 via the air hose 116. When the door 151 is in the open position, the connection between the air hose 116 and the connector air inlet 179 is broken, so that air is not supplied to the capsule 170.

[0145] 9A-9C illustrate a capsule according to at least one exemplary embodiment. More specifically, FIG. 9A illustrates a top and front perspective view of a capsule according to some exemplary embodiments. FIG. 9B illustrates a bottom and front perspective view of the capsule. FIG. 9C illustrates a heater of the capsule according to some exemplary embodiments.

[0146] As shown in FIG. 9A , the exterior of capsule 170 may include, but is not limited to, a proximal end cap 210, a distal end cap 220, and / or an outer shell 205. Capsule 170 may include a housing 205 and a heater 230 (e.g., FIG. 4C ) within housing 205. Housing 205 of capsule 170 has an inner surface defining at least one chamber configured to hold an aerosol-generating substance. Proximal end cap 210 (e.g., a first surface and / or a first end) and distal end cap 220 (e.g., a second surface and / or a second end) of capsule 170 may be aerosol-permeable. For example, proximal end cap 210 may further include at least one aerosol outlet 212, thereby facilitating the flow of aerosol from at least one chamber of housing 205 to chimney 161. Distal end cap 220 may further include at least one capsule air inlet 222, thereby facilitating the flow of air from air hose 116 to at least one chamber of housing 205. Additionally, distal end cap may define a recess 221 (e.g., alignment recess) that may further include, but is not limited to, electrical contacts (e.g., electrodes) 224 and at least one air inlet 222. Recess 221 may be an alignment recess that forms a seal and / or connection (e.g., mates) with angled, flat alignment feature 178 on the proximal end of capsule connector 177, where capsule 170 and capsule connector 177 form a suitable electrical and sealed fluid connection.

[0147] While the figures depict capsule 170 as resembling a rectangle with curved sides and / or oval ends (e.g., an oval cross-section), it should be understood that other configurations may be used. For example, in some examples, capsule 170 may have an oval or ellipsoid shape with an oval or oval cross-section. In other examples, capsule 170 may have a rectangular shape with a rectangular cross-section (e.g., a rectangular prism other than a rounded cube). The chamber defined within capsule 170 may have the same shape as the exterior of capsule 170, or may have a different shape. For example, the cross-section of the chamber and the cross-section of the exterior of capsule 170 may both be oval. In another example, the cross-section of the chamber may not be oval (e.g., rectangular) and the cross-section of the exterior of capsule 170 may be oval (or vice versa).

[0148] As used herein, an aerosol-generating material is a material, or combination of materials, capable of producing an aerosol. An aerosol is a substance generated or produced by the devices disclosed and claimed herein and their equivalents. Such materials can include compounds (e.g., nicotine, cannabinoids) that, when heated, produce an aerosol containing the compounds. Heating can be below combustion temperatures, thereby producing the aerosol without substantial thermal decomposition of the aerosol-generating material or substantial generation of combustion by-products, if any. Thus, in certain exemplary embodiments, no thermal decomposition occurs during heating and the resulting production of the aerosol. In other examples, some thermal decomposition and combustion by-products may occur, but the extent may be relatively minor and / or may be considered merely incidental.

[0149] The aerosol-generating material can be a fibrous material. The fibrous material can be, for example, a plant material. The fibrous material is configured to release a compound when heated. The compound can be a natural component of the fibrous material. The fibrous material can be, for example, a plant material, such as tobacco, and the released compound can be nicotine. The term "tobacco" includes any tobacco plant material, including tobacco leaf, tobacco plugs, reconstituted tobacco, compressed tobacco, shaped tobacco, or powdered tobacco obtained from one or more species of tobacco plant, such as Nicotiana rustica and Nicotiana tabacum, and combinations thereof.

[0150] In some exemplary embodiments, the tobacco material may include material obtained from any member of the Nicotiana genus. Furthermore, the tobacco material may include a blend of two or more different tobacco species. Examples of suitable types of tobacco material that may be used include, but are not limited to, flue-cured tobacco, burley tobacco, dark tobacco, Maryland tobacco, Oriental tobacco, rare tobacco, specialty tobacco, blends thereof, and the like. The tobacco material may be provided in any suitable form, including, but not limited to, tobacco layers, processed tobacco materials (e.g., expanded or expanded tobacco), processed tobacco stems (e.g., cut rolled or cut expanded stems), reconstituted tobacco materials, blends thereof, and the like. In some exemplary embodiments, the tobacco material is in the form of a substantially dry tobacco mass. Furthermore, in some exemplary embodiments, the tobacco material may be mixed and / or combined with at least one of propylene glycol, glycerin, subcombinations thereof, or combinations thereof.

[0151] The compound may also be a natural component of a medicinal plant that has a medically acceptable therapeutic effect. For example, the medicinal plant may be the cannabis plant, and the compound may be a cannabinoid. Cannabinoids interact with receptors in the body to produce a wide range of effects. As a result, cannabinoids have been used for a variety of medical purposes (e.g., treating pain, nausea, epilepsy, and psychiatric disorders). The fibrous material may include leaf and / or flower material from one or more species of the cannabis plant (e.g., Cannabis sativa, Cannabis indica, and Cannabis ruderalis). In some examples, the fibrous material is a mixture containing 60-80% (e.g., 70%) Cannabis sativa and 20-40% (e.g., 30%) Cannabis indica.

[0152] Examples of cannabinoids include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiol acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC), and cannabigerol (CBG). Tetrahydrocannabinolic acid (THCA) is a precursor of tetrahydrocannabinol (THC), and cannabidiol acid (CBDA) is a precursor of cannabidiol (CBD). Tetrahydrocannabinolic acid (THCA) and cannabidiol acid (CBDA) can be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, by heating. In certain exemplary embodiments, the heat from the heater may cause decarboxylation, thereby converting tetrahydrocannabinolic acid (THCA) in capsule 170 to tetrahydrocannabinol (THC) and / or converting cannabidiolic acid (CBDA) in capsule 170 to cannabidiol (CBD).

[0153] In examples where tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are both present in capsule 170, decarboxylation and the resulting conversion will decrease tetrahydrocannabinolic acid (THCA) and increase tetrahydrocannabinol (THC). During heating of capsule 170, at least 50% (e.g., at least 87%) of the tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC). Similarly, in examples where cannabidiolic acid (CBDA) and cannabidiol (CBD) are both present in capsule 170, decarboxylation and the resulting conversion will decrease cannabidiolic acid (CBDA) and increase cannabidiol (CBD). During heating of capsule 170, at least 50% (e.g., at least 87%) of the cannabidiolic acid (CBDA) may be converted to cannabidiol (CBD).

[0154] Furthermore, the compound may be or may further include a non-natural additive, which is then introduced into the fibrous material. In one example, the fibrous material may include at least one of cotton, polyethylene, polyester, rayon, combinations thereof, and the like (e.g., in the form of gauze). In another example, the fibrous material may include a natural material, such as a cellulosic material (e.g., a non-tobacco material and / or a non-cannabis material). In either example, the introduced compound may include nicotine, a cannabinoid, and / or a flavoring agent. The flavoring agent may be from a natural source, such as a plant extract (e.g., tobacco extract, cannabis extract), and / or may be from an artificial source. In yet another example, when the fibrous material includes tobacco and / or cannabis, the compound may be or may further include one or more flavoring agents (e.g., menthol, mint, vanilla). Thus, the compound in the aerosol-generating material may include natural components and / or non-natural additives. In this regard, it should be understood that the level of natural components present in the aerosol-generating material may be increased by supplementation. For example, the level of nicotine present in a quantity of tobacco can be increased by supplementing it with a nicotine-containing extract, and similarly, the level of one or more cannabinoids present in a quantity of cannabis can be increased by supplementing it with a cannabinoid-containing extract.

[0155] As shown in Figures 9B and 9C, in at least one exemplary embodiment, at least one heater 230 is configured to generate Joule heating (also known as ohmic heating / resistive heating) when an electric current is applied thereto. More specifically, the heater 230 may be formed of one or more conductors and configured to generate heat when an electric current flows through the heater 230. The electric current may be supplied to the heater 230 from a power source (e.g., a battery) 182 within the aerosol generating device 100. Suitable conductors for the heater 230 include, but are not limited to, iron-based alloys (e.g., stainless steel) and / or nickel-based alloys (e.g., nichrome). The heater 230 may have a thickness of approximately 0.1-0.3 mm (e.g., 0.15-0.25 mm) and a resistance of approximately 0.5-2.5 ohms (e.g., 1.0-2.0 ohms), but is not limited thereto.

[0156] Current from the power source 182 within the aerosol generating device can be transmitted from the horizontal electrical contact 171 of the capsule connector 177 through an electrode 224 on the distal end cap 220 configured to electrically contact the heater 230. In a non-limiting embodiment, the electrode 224 can be spring-loaded to enhance engagement of the capsule 170 with the heater 230. Furthermore, movement (e.g., engagement, disengagement) of the electrode can be achieved by mechanical actuation. Furthermore, the delivery of current from the aerosol generating device 100 to the capsule 170 can be manual (e.g., button actuation using button 106, etc.) or automatic (e.g., puff-activated).

[0157] Further details of the aerosol-generating devices, capsules, and / or aerosol-generating materials and / or alternatives thereof can be found in concurrently filed U.S. patent application Ser. No. __ / ______, entitled "Capsules Including Embedded Heaters And Heat-Not-Burn (HNB) Aerosol-Generating Devices" (Attorney Docket No. 24000NV-000667-US), concurrently filed U.S. patent application Ser.

[0158] FIG. 10 illustrates the internal configuration of a first portion of an aerosol generating device according to at least one exemplary embodiment.

[0159] 10 , the first portion 105 includes, but is not limited to, at least one connector port 114, at least one main body housing air inlet 113, at least one air hose 116, at least one flow sensor 181 (e.g., a flow sensor, etc.), a control subsystem 180, and / or at least one power source 182. When connected to an external power source, the connector port 114 supplies power to the electrical circuitry of the aerosol generating device 100 and / or recharges the battery 182. Furthermore, the air inlet 113 supplies air from outside to the at least one air hose 116. The air hose 116 may also be connected to the flow sensor 181, which is configured to detect the application of negative air pressure (e.g., a puff, etc.) and / or air flow within the air hose 116 and provide a control signal to the control subsystem 180 (e.g., a processing circuit, control circuit, controller, processor, etc.). In response to flow sensor 181 detecting negative air pressure in at least one air hose 116, the control subsystem may send a control signal to battery 182, thereby supplying current (e.g., power) to the heater to heat the aerosol-generating material, although example embodiments are not limited thereto. For example, the control system may be further configured to selectively electrically connect battery 182 to supply current to the heater, such as in response to button 106 being pressed. Furthermore, as a second condition to be satisfied before supplying current to the heater, the control subsystem may enable supply of current to the heater based on, for example, a capsule being detected by the capsule detection switch and suction and / or negative air pressure being detected by flow sensor 181, and / or button 106 being actuated.

[0160] In at least one exemplary embodiment, the power source 182 is a battery, such as a lithium-ion battery. The battery may be a lithium-ion battery or one of its variants, such as a lithium-ion polymer battery. Alternatively, the battery may be a nickel-metal hydride battery, a nickel-cadmium battery, a lithium-manganese battery, a lithium-cobalt battery, a fuel cell, or a solar cell. Any other power source or battery technology may be used. In certain exemplary embodiments, the aerosol generating device 100 can be used until the energy in the power source 182 is depleted and / or drops below a certain threshold. Alternatively, the power source 182 may be rechargeable and reusable, and may include circuitry that allows the battery to be charged by an external charging device or may be rechargeable using solar power. In some exemplary embodiments, the circuitry of the control system 180, once charged, can provide power for a desired (or predetermined) number of inhalations until the energy in the power source 182 is depleted and / or drops below a certain threshold, after which the circuitry must be reconnected to an external charging device.

[0161] FIG. 11 is an exemplary block diagram of a control subsystem of an aerosol generating device according to some exemplary embodiments.

[0162] 11 , according to at least one exemplary embodiment, control subsystem 2100 (which may correspond, for example, to control subsystem 180 of FIG. 10 ) includes, but is not limited to, a controller 2105, a power supply 2110, an actuator control 2115, a capsule electrical / data interface 2120, device sensors 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, control subsystem 2100 may include additional elements, which are not described for the sake of brevity. In another exemplary embodiment, capsule electrical / data interface 2120 may be only an electrical interface, for example.

[0163] The controller 2105 (e.g., processing circuitry, control circuitry, etc.) may be hardware including logic circuitry, a hardware / software combination such as a processor executing software, or a combination thereof. 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-chip (SoC), a programmable logic unit, a microprocessor, an application-specific integrated circuit (ASIC), etc.

[0164] In the event that controller 2105 is or includes process-executing software, controller 2105 is configured as a dedicated machine (e.g., processing device) to achieve the functions of controller 2105 by executing software stored in memory (e.g., storage medium 2145 or other storage device) accessible to controller 2105. The software may be embodied as program code including instructions that perform and / or control any or all of the operations described herein as being performed by controller 2105.

[0165] As used herein, the terms "storage medium," "computer-readable storage medium," or "non-transitory computer-readable storage medium" refer to one or more of a device for storing data, including read-only memory (ROM), random-access memory (RAM), magnetic RAM, core memory, magnetic disk storage media, optical storage media, flash memory media, and / or other tangible, machine-readable media for storing information. The term "computer-readable medium" can include, but is not limited to, portable or non-removable storage media, optical storage media, and various other media that can store, contain, or carry instructions and / or data.

[0166] The controller 2105 communicates with a power source 2110, actuator controls 2115, an electrical / data interface 2120, device sensors 2125, an input / output (I / O) interface 2130, an aerosol indicator 2135, on-product controls 2150, and / or at least one antenna 2140, etc. According to at least some exemplary embodiments, the on-product controls 2150 may include a device operable by an adult operator to indicate value selections. Example implementations include, but are not limited to, one or more buttons (such as, for example, button 106), dials, capacitive sensors, sliders, etc.

[0167] The I / O interface 2130 and antenna 2140 enable the control subsystem 2100 to connect to various external devices, such as a smartphone, tablet, PC, 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 source 2110b (e.g., battery 182), and the USB-C connector may also be used to send and receive data to and from at least one external device, although example embodiments are not limited thereto. Such data may include, for example, an aerosol profile, a heater profile, device performance log data (e.g., controller performance data, memory performance data, battery performance data, heater performance data, etc.), firmware updates, software updates, etc.

[0168] The controller 2105 may include on-board ROM and flash memory to store and execute code, including analysis, diagnostics, and software updates. Alternatively, the storage medium 2145 may store the code. Additionally, in another exemplary embodiment, the storage medium 2145 may be mounted on the controller 2105.

[0169] The controller 2105 may further include an on-board clock, reset and power management module to reduce the area covered by the PCB within the device body housing 101 .

[0170] The device sensors 2125 may include multiple sensor transducers that provide measurement information to the controller 2105. The device sensors 2125 may include 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 to monitor movement and orientation. 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 181) may be a pressure sensor (e.g., a capacitive pressure sensor, etc.) configured to detect positive or negative air pressure (e.g., suction or puffing), 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 disposed within the capsule 170 instead of, or in addition to, being measured using a flow sensor included in the device sensor 2125 of the control subsystem 2100 of the device body housing 101. According to at least one exemplary embodiment, the device sensor 2125 further includes a capsule detection sensor, e.g., capsule detection sensor 183, that detects the presence of a capsule within the aerosol generating device 100, and / or a door detection switch, e.g., door detection switch 186, that detects that the door and / or lid of the aerosol generating device is closed, although exemplary embodiments are not limited thereto.

[0171] Data generated from one or more device sensors 2125 may be detected based on binary signals (e.g., on / off signals) using general-purpose input / output (GPIO) circuits, etc., and / or may be sampled at a sample rate appropriate for the parameter being measured, using, for example, a discrete multi-channel analog-to-digital converter (ADC), etc.

[0172] The controller 2105 may apply heater profiles for the aerosol-generating material and other profiles based on measurement information received from the controller 2105. For convenience, these are collectively referred to as aerosol profiles. The heater profile identifies the power profile supplied to the heater during the few seconds that aerosol aspiration occurs and / or the power profile supplied to the heater between aerosol aspirations for continuous heating of the capsule (e.g., 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 full power to the heater when aerosol aspiration begins, but then reduce the power to half or a quarter after about one second. According to at least some exemplary embodiments, modulation of the power supplied to the heater may be performed using, but not limited to, pulse-width modulation.

[0173] Additionally, the heater profile may be modulated based on the detection of suction and / or application of negative pressure to the aerosol generating device 100. Using a flow sensor, the strength of the aerosol suction can be measured and used as feedback to the controller 2105, which then adjusts the power delivered to the heater of the capsule, which can be referred to as heating or energy delivery.

[0174] According to at least some exemplary embodiments, when the controller 2105 recognizes the currently installed capsule 170 (e.g., via a unique identifier included in the SKU, etc.), the controller 2105 matches the associated heating profile designed for that particular capsule. The controller 2105 and storage medium 2145 store data and algorithms that enable heating profiles to be generated for all SKUs, all types of capsules, all types of aerosol-generating material, etc. In another exemplary embodiment, the controller 2105 may read the heating profile from the capsule. Additionally, an adult operator may adjust the heating profile to their liking using the on-product controls 2150 and / or an external device wirelessly paired with the aerosol generating device 100 and / or connected to the aerosol generating device 100 via the I / O interface 2130, etc. In another exemplary embodiment, the controller 2105 may apply to the currently installed capsule the heating profile that was applied to the previously installed capsule and that is stored in memory. This is done assuming that the current capsule is the same type as the previously installed capsule.

[0175] The controller 2105 may send and receive data to and from the power supply 2110. The power supply 2110 includes a power supply 2110b and a power supply controller 2110a to manage the output of power by the power supply 2110b.

[0176] The power source 2110b can be a lithium-ion battery or one of its variants, such as a lithium-ion polymer battery. Alternatively, the power source 2110b can 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 source 2110b can be rechargeable and include circuitry that allows the battery to be charged by an external charging device. In this case, once charged, the circuitry provides power for a desired (or predetermined) number of aerosol inhalations, after which the circuitry must be reconnected to the external charging device.

[0177] In addition to powering the capsule, the power supply 2110 also powers the controller 2105. Additionally, the power controller 2110a provides feedback to the controller 2105 indicative of the performance of the power supply 2110b.

[0178] The controller 2105 transmits and receives data to and from 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 technologies (e.g., WiFi, etc.). In an exemplary embodiment, the communication stack resides within the modem, which is controlled by the controller 2105. The Bluetooth LE modem is used for data and control communication with applications on external devices (e.g., smartphones, etc.). The NFC / Bluetooth LE / WiFi 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. Additionally, the Bluetooth LE / WiFi modem may be used to provide location information (to allow an adult operator to locate the aerosol generating device) or authentication during purchase, etc.

[0179] 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 an adult operator.

[0180] The actuator control 2115 includes passive and active actuators to regulate the desired aerosol profile. For example, the device body housing 101 may include actuators within the air inlet passage and / or air inlet channel of the device body housing 101, such as within the airflow subsystem of the aerosol generating device 100 (e.g., the body housing air inlet 113, the air hose 116, the capsule connector 179, etc.). The actuator control 2115 may use the actuators to control the flow of air within the air inlet channel based on commands from the controller 2105 related to the desired aerosol profile.

[0181] Additionally, actuator control 2115 is used in conjunction with power supply 2110 to energize the heater. More specifically, actuator control 2115 is configured to generate a drive waveform associated with a desired aerosol profile. As discussed above, each possible profile is associated with a drive waveform. Upon receiving a command from controller 2105 indicating the desired aerosol profile, actuator control 2115 can generate the associated modulated waveform for power supply 2110.

[0182] Controller 2105 indicates the status and current action to the adult operator by providing information to aerosol indicator 2135. Indicator 2135 includes a power indicator displayed on display panel 107A, a separate indicator light (e.g., an LED indicator light, etc.) that can be activated when controller 2105 senses that the adult operator has pressed a button, and / or other feedback mechanisms. Indicator 2135 can also include a haptic feedback motor (e.g., haptic feedback motor 185), a speaker, an indicator showing the current state of an aerosol parameter controlled by the adult operator (e.g., volume of aerosol generated), and other feedback mechanisms.

[0183] In at least some exemplary embodiments, an aerosol generating device according to at least some exemplary embodiments (e.g., the aerosol generating device 100 shown in FIGS. 1-11 ) is configured to generate an aerosol by heating a capsule (e.g., capsule 170). In certain exemplary embodiments, a method of generating an aerosol may include first loading the capsule 170 into the aerosol generating device 100. To load the capsule 170, the door 151 is rotated and / or pivoted to an open position and the capsule 170 is inserted into the capsule receiving portion 175 (e.g., a capsule receiving cavity, etc.). The door 151 is then rotated to a closed position so that the door 151 contacts the device body housing 101; This causes attached linkages 121 and 122 to move capsule receiving portion 175 distally, connecting capsule 170 to capsule connector 177. Door 151 maintains the closed position while pushing capsule 170 further into capsule receiving portion 175 until capsule 170 is fully seated within capsule receiving portion 175. Simultaneously, by pivoting door 151 to the closed position, attached linkages 121 and 122, along with biased spring 123, move mouthpiece chassis 155 distally, causing mouthpiece 160 to contact device body housing 101 and causing mouthpiece chimney 161 and aerosol flow path 165 to align with and contact capsule 170.

[0184] When the capsule 170 is fully seated within the capsule receiving portion 175, the distal portion of the capsule 170 presses against the electrical contacts 171 (e.g., the electrical contacts 224 of the capsule 170 press against the exposed tips of the contact surfaces 171), causing the electrical contacts 171 to compress and retract via the spring features 171A of the contacts 171. While pressed against the electrical contacts 171, the distal end of the capsule 170 may also contact the flat, angled surface of the capsule connector sealing element 178 within the capsule connector 177, causing the recess 221 (e.g., the alignment recess) of the capsule 170 to contact or abut the angled surface of the alignment member within the capsule receiving portion 175. In other words, the inlet recess 221 of the capsule 170 may receive the capsule connector sealing element 178 in a resilient, sealing engagement. As a result, a relatively stable electrical connection and a desired sealing state with the capsule 170 may be established.

[0185] The aerosol-generating device 100 may be activated using the display panel 107 (e.g., by pressing the power button 106) and / or upon detection of an inhalation event (e.g., via the flow sensor 181). Upon activation, the control subsystem 2100 is configured to direct the power button 182 to supply electrical current to the capsule 170 via electrical contacts 171 within the capsule connector 177. Specifically, the capsule 170 includes a heater 230. The heater 230 is configured to be resistively heated in response to electrical current from the power source 182 introduced through the distal end. The resistive heating results in an increase in the temperature of the aerosol-generating material within the capsule 170, which releases volatile materials and generates the aerosol. In at least one exemplary embodiment, the heating of the aerosol-generating material within the capsule 170 may be performed below the combustion temperature of the aerosol-generating material, thereby producing an aerosol without substantial thermal decomposition of the aerosol-generating material or substantial generation of combustion by-products, if any. Thus, in at least one exemplary embodiment, no thermal decomposition occurs during heating and the resulting production of the aerosol. In other instances, there may be some thermal decomposition and combustion by-products, but these may be considered relatively minor and / or merely incidental.

[0186] When suction or negative pressure is applied to the aerosol generating device 100 (e.g., via the mouthpiece 160), ambient air is drawn into the aerosol generating device 100 through the perforations in the grille covering the main housing air inlet 113. Once inside, the air flow from the perforations in the grille cover converges, passes through the main housing air inlet 113, and enters the air hose 116, which is sealingly connected to the air inlet 113. The converged air flow may be optionally detected / monitored by a flow sensor 181 within the main housing air inlet 113 and / or the air hose 180. The air flow is directed from the air hose 116 toward the capsule connector air inlet 179 of the capsule connector 177. The air flow then passes through the capsule connector sealing element 178 and enters the inlet opening 222 in the capsule 170. Inside the capsule 170, air may flow (e.g., longitudinally) through the aerosol-generating material and along the surface of the heater 230, thereby entraining volatile substances released by the aerosol-generating material. This results in the generation of an aerosol. Finally, the resulting aerosol passes through the outlet opening 212 in the capsule 170, through the mouthpiece chimney 161, and then out of the aerosol generation device 100 (e.g., via one or more outlets 165B of the mouthpiece 160).

[0187] In at least some exemplary embodiments, a method of use for the aerosol generating device 100 may include securing a replaceable mouthpiece (e.g., the replaceable mouthpiece 160). For example, the method may include inserting the replaceable mouthpiece 160 into a mouthpiece opening in the proximal end piece 152 of the device body housing 101 and turning the replaceable mouthpiece 160 until the replaceable mouthpiece locks into the mouthpiece chassis 155, e.g., until resistance is felt and / or a click is heard. The resistance or click indicates that the bayonet connector 162 of the replaceable mouthpiece 160 has locked into the bayonet enclosure 163 of the mouthpiece chassis 155. In at least some exemplary embodiments, the method of use may include replacing the replaceable mouthpiece (e.g., the replaceable mouthpiece 160). Replacing the interchangeable mouthpiece may include moving the interchangeable mouthpiece to an open position away from the proximal end piece (e.g., 152) of the device body housing (e.g., 101) by opening a door (e.g., 151), removing the first interchangeable mouthpiece from the opening by disengaging the bayonet connector (e.g., 162) from the bayonet enclosure (e.g., 163) of the mouthpiece chassis (e.g., 155), and inserting a second interchangeable mouthpiece into the opening and turning the second interchangeable mouthpiece until it locks into the mouthpiece chassis (e.g., until resistance is felt and / or a click is heard).

[0188] Although the capsule 170 has been shown as one embodiment in connection with the aerosol generating device 100, it should be understood that other suitable embodiments are possible.

[0189] While a number of exemplary embodiments have been described herein, it should be understood that other variations are possible. Such variations should not be considered a departure from the spirit and scope of the present disclosure, and it is intended that all modifications obvious to those skilled in the art be included within the scope of the following claims.

[0190] Those skilled in the art will recognize that various modifications, additions, and substitutions of the exemplary embodiments may be made with reference to the specific examples and drawings described herein; for example, the techniques described may be performed in a different order than the methods and / or elements of systems, configurations, devices, circuits, etc. described, and may be connected or combined differently than those described above, or results may be achieved with other elements or equivalents, as appropriate.
