[0021] In one embodiment, the mounting channel extends through the storage tray, the drive shaft extends into the mounting channel through one axial end, and the fastener is disposed within the mounting channel through the other axial end.

[0022] In one embodiment, the fastener includes a top cover and side panels surrounding the outer periphery of the top cover. Along the circumference of the mounting channel, the side panels respectively limit the movement of the elastic element and the side wall of the mounting channel, and the top cover seals the other end of the mounting channel.

[0023] In one embodiment, the fastener is provided with a receiving groove, and at least a portion of the drive shaft is located within the receiving groove.

[0024] This application provides an aerosol generating apparatus, comprising:

[0025] The main unit includes a main shell and a heating assembly. The main shell has a mounting area extending along a second direction. The two ends of the mounting area along the second direction are a first end and a second end, respectively.

[0026] An atomizing medium assembly includes a strip medium and a housing having a heating area, wherein a portion of the strip medium is disposed within the heating area, and the two ends of the housing along the second direction are an assembly end and a mating end, respectively.

[0027] The main shell has a first mating part, and the housing has a second mating part. During the process of the mating end abutting against the first end and the assembly end rotating about the mating end towards the installation area, the first mating part and the second mating part can interfere to limit the rotation of the assembly end and keep the heating component separated from the strip medium. During the process of the assembly end abutting against the second end and the mating end rotating about the assembly end towards the installation area, the first mating part and the second mating part cooperate to allow the housing to be assembled within the installation area, and at least a portion of the heating component extends into the heating area to heat the strip medium.

When the mating end abuts against the first end and the assembly end rotates around the mating end in the direction of entering the installation area, the sidewall of the track boss and the sidewall of the track groove can interfere with each other. When the assembly end abuts against the second end and the mating end rotates around the assembly end in the direction of entering the installation area, the track boss can move freely around the assembly end in the track groove.

[0030] In one embodiment, the first mating part is the track boss. Along the second direction, the distance between the track boss and the first end is less than the distance between the heating component and the first end, and the distance between the side of the track boss facing the first end and the side of the heating component facing the first end is not less than 4 mm.

When the housing is assembled in the mounting area, the sidewalls of the track boss and the track groove on opposite sides along the second direction are both bent away from the second end.

[0033] In one embodiment, with the housing assembled in the mounting area, the strip medium in the heating area is located on the side of the heating assembly facing the first end.

The atomizing medium assembly further includes a storage tray disposed in the storage space and a receiving tray disposed in the receiving space. The storage tray is used to wind the strip medium, and the strip medium can be unwound from the storage tray and wound onto the receiving tray after passing through the heating area.

[0037] In one embodiment, the main unit further includes a drive shaft, wherein, with the housing assembled in the mounting area, at least a portion of the drive shaft extends into the storage space and is driven to connect with the storage tray.

[0038] This application provides an atomizing medium assembly, including:

[0039] The housing has a heating area, an air outlet channel, and a negative pressure air channel. The two ends of the air outlet channel are respectively connected to the heating area and the outside. One end of the negative pressure air channel is connected to the air outlet channel, and the other end is connected to the negative pressure sensor of the aerosol generating device.

[0040] A strip-shaped medium that can partially move into the heating area and be heated to generate an aerosol;

[0041] Specifically, on a plane perpendicular to the axis of the air outlet channel, the projection of the axis of the negative pressure airway has a first angle with the thickness direction of the housing, and the first angle is not 0°.

[0042] In one embodiment, the first included angle is not less than 45°.

[0043] In one embodiment, the first included angle is 90°.

[0044] In one embodiment, the negative pressure airway extends from one end connected to the air outlet channel to the end connected to the negative pressure sensor in a fifth direction, and the air outlet channel extends from one end connected to the heating area to the end connected to the outside in a sixth direction. The fifth direction and the sixth direction have a second included angle, which is not greater than 90°.

[0045] In one embodiment, the second included angle is not less than 30° and not greater than 60°.

[0046] In one embodiment, the direction from one end of the air outlet channel that connects to the heating area to the other end that connects to the outside is a sixth direction. Along the sixth direction, the air outlet channel includes a constriction section, a throat section, and an expansion section. The throat section connects the constriction section and the expansion section. One end of the negative pressure airway is connected to the throat section.

[0047] In one embodiment, the end of the housing has a protruding post, at least a portion of the air outlet channel and the negative pressure air channel are disposed on the protruding post, and the protruding post is used to connect with the suction component of the aerosol generating device.

[0048] In one embodiment, the housing further has a storage space and a receiving space, the storage space and the receiving space being separated. The atomizing medium assembly further includes a storage tray disposed in the storage space and a receiving tray disposed in the receiving space. The storage tray is used to wind the strip medium, and the strip medium can be unwound from the storage tray and wound onto the receiving tray after passing through the heating area.

[0049] This application provides an aerosol generating apparatus, comprising:

[0050] The main unit includes a negative pressure sensor;

[0051] The atomizing medium assembly described in any of the above embodiments is detachably mounted on the host, and the end of the negative pressure airway away from the air outlet channel is connected to the negative pressure sensor;

[0053] In one embodiment, the suction member is flat, and the thickness direction of the suction member is parallel to the thickness direction of the shell.

[0054] In one embodiment, the host is flat, and the thickness direction of the host is parallel to the thickness direction of the housing.

[0055] In one embodiment, the host further includes a sealing element with a sealing channel. The two ends of the sealing element are respectively connected to the negative pressure sensor and the housing, so that the negative pressure air passage communicates with the sensor through the sealing channel.

[0056] In the aerosol generating device of this application embodiment, a portion of the receiving tray structure is capable of elastic deformation. During the insertion of the drive shaft into the installation channel, the drive shaft presses against the receiving tray, causing the pressed portion of the tray to elastically deform under the pressure. This facilitates the drive shaft's continued advancement into the installation channel. After the drive shaft is properly assembled, the elastically deformed portion of the receiving tray can recover its elastic deformation. This allows the drive shaft to achieve a circumferential positioning fit with the receiving tray, and the rotation of the drive shaft drives the receiving tray to rotate. In other words, the aerosol generating device of this application embodiment expands the installation angle range between the installation channel and the drive shaft, thus facilitating the installation of the atomizing medium component on the main unit and improving the assembly efficiency of the aerosol generating device.

[0096] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0097] Please refer to Figures 1 to 13. This application provides an aerosol generating device, which includes an atomizing medium component 100 and a main unit 200. The atomizing medium assembly 100 includes a receiving tray 40, a storage tray 30, a strip medium 20, and a housing 10 having a heating zone 10a. The receiving tray 40 and the storage tray 30 are both disposed within the housing 10. The storage tray 30 is used to wind the strip medium 20. The strip medium 20 can be unwound from the storage tray 30, passed through the heating zone 10a, and then wound onto the receiving tray 40. The strip medium 20 can be heated within the heating zone 10a to generate an aerosol. The main unit 200 includes a drive shaft 240 that is drivenly connected to the receiving tray 40. The drive shaft 240 is configured to drive at least a portion of the receiving tray 40 to rotate. The receiving tray 40 includes an installation channel 41a. During the process of the drive shaft 240 extending into the installation channel 41a, a portion of the structure of the receiving tray 40 can undergo elastic deformation. When the drive shaft 240 is in the assembled state, the receiving tray 40 restores its elastic deformation and is limited to the drive shaft 240 along its circumference.

[0098] The specific structure of the housing 10 is not limited, and it can be used to contain the strip medium 20. For example, referring to Figures 6 to 9, the housing 10 includes a first outer shell 11 and a second outer shell 12, which are disposed opposite to each other and define a heating zone 10a. The strip medium 20 can be disposed in the area between the first outer shell 11 and the second outer shell 12. The first outer shell 11 and the second outer shell 12 can be detachably connected, so that after the strip medium 20 is used, a new strip medium 20 can be replaced, and the housing 10 can be reused, thereby reducing the user's operating costs.

[0099] The strip medium 20 is a flexible strip structure with a certain width and thickness, but its length can be extended and bent according to actual conditions.

[0100] The surface of the strip medium 20 is coated or the interior is infiltrated or embedded with an aerosol generating matrix for generating aerosols. The aerosol generating matrix includes, but is not limited to, pharmaceuticals or nicotine-containing materials.

[0101] For example, the strip medium 20 may include a base strip and an aerosol generating matrix that is alternately coated on the base strip.

[0102] The base tape can be any strip that can withstand heating temperatures, possesses a certain degree of flexibility, and can be unwound and rewound, such as paper strips, polymer strips, metal base tapes, graphite base tapes, etc. The base tape can also be a metal mesh, which can be formed by weaving metal wires or by setting multiple through holes in a metal sheet.

[0103] Unwinding refers to the process of peeling the outer and inner layers of a rolled substrate radially. Rewinding refers to the method of taking continuous products into winding using a roll, reel, or similar device.

[0104] A portion of the strip medium 20 can move into the heating zone 10a and be heated to generate an aerosol. That is, the strip medium 20 can continuously pass through the heating zone 10a, and the aerosol-generating matrix on the portion of the strip medium 20 currently within the heating zone 10a can generate an aerosol. It is understood that once the entire strip medium 20 has passed through the heating zone 10a, it is considered that the strip medium 20 has been used up.

[0105] The housing 10 can store and contain the strip medium 20, that is, the unused strip medium 20 is stored in the housing 10. During the use of the atomizing medium assembly 100, the unused strip medium 20 passes through the heating zone 10a in sequence and is heated and used. The used strip medium 20 is still stored in the housing 10.

[0106] During the aerosol extraction process, the rotation of the drive shaft 240 can drive the storage tray 40 to rotate. Through the rotation of the storage tray 40, the used strip medium 20 can be wound onto the storage tray 40. At the same time, the storage tray 30 follows the movement of the storage tray 40, causing the strip medium 20 stored on the storage tray 30 to unwind.

[0107] It should be noted that, as shown in Figures 10 and 11, in some embodiments, the storage tray 40 can be a one-piece structure, in which case the drive shaft 240 drives the storage tray 40 to rotate as a whole. In other embodiments, the storage tray 40 can also be a split structure. For example, the storage tray 40 includes a first part and a second part that are joined together along its axial direction. One of the first part and the second part is driven to be connected to the drive shaft 240 to wind the strip medium 20, while the other part does not rotate.

[0108] By setting up the storage disk 30, the storage disk 30 can be rotated, which facilitates the unwinding of the strip medium 20 from the storage disk 30 and reduces the friction between the strip medium 20 and the housing 10 during the unwinding process.

[0109] By setting up a storage tray 40, the storage tray 40 can be rotated, which helps to wind the strip medium 20 onto the storage tray 40 and reduce the friction between the strip medium 20 and the housing 10 during the winding process.

[0110] The specific method by which the strip medium 20 generates an aerosol within the heating region 10a is not limited. For example, referring to Figures 2 to 4, the host 200 includes a heating component 220, and the strip medium 20 within the heating region 10a generates an aerosol under the influence of the heating component 220. The heating method of the heating component 220 includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating, and laser heating. Of course, atomization can also be achieved using methods such as ultrasound; no specific limitation is made here.

[0111] During the insertion of the drive shaft 240 into the mounting channel 41a, a portion of the structure of the receiving tray 40 can undergo elastic deformation. That is, during the insertion of the drive shaft 240 into the mounting channel 41a, a portion of the structure of the receiving tray 40 may undergo elastic deformation. For example, when the drive shaft 240 is inserted into the mounting channel 41a in a non-parallel manner to the axial direction of the mounting channel 41a, the drive shaft 240 may compress the receiving tray 40. Under this compressive force, the receiving tray 40 undergoes elastic deformation, allowing the drive shaft 240 to continue extending into the mounting channel 41a. Conversely, when the drive shaft 240 is inserted into the mounting channel 41a in a parallel manner to the axial direction of the mounting channel 41a, the drive shaft 240 may not compress the receiving tray 40. The receiving tray 40 is not subject to compressive force and will not undergo elastic deformation; the drive shaft 240 can still be properly installed.

[0112] It should be noted that when the drive shaft 240 is assembled, the axial direction of the drive shaft 240 is parallel to the axial direction of the mounting channel 41a.

[0113] The state in which the drive shaft 240 is assembled refers to the state in which at least one side of the drive shaft 240 forms a limiting engagement with the storage tray 40 along the circumference of the storage tray 40, that is, the state in which the rotation of the drive shaft 240 can drive the storage tray 40 to rotate.

[0114] In related technologies, the storage tray is a rigid structure. During the installation of the atomizing medium assembly, the axial direction of the installation channel must be parallel to the axial direction of the drive shaft, and the storage tray and drive shaft must be able to achieve a limiting fit angle along the circumference of the storage tray to enable the installation of the atomizing medium assembly. If the axial direction of the installation channel is not parallel to the axial direction of the drive shaft, or if the installation angle of the storage tray along its circumference does not meet the limiting fit angle with the drive shaft, interference will occur between the drive shaft and the storage tray, preventing the drive shaft from being properly assembled. This makes the installation of the atomizing medium assembly inconvenient.

[0115] In the aerosol generating device of this application embodiment, a portion of the structure of the receiving tray 40 can undergo elastic deformation. During the process of the drive shaft 240 extending into the installation channel 41a, after the drive shaft 240 presses against the receiving tray 40, the pressed portion of the receiving tray 40 can undergo elastic deformation under the pressure, thus facilitating the drive shaft 240 to continue advancing into the installation channel 41a. After the drive shaft 240 is assembled in place, the portion of the receiving tray 40 that has undergone elastic deformation can recover its elastic deformation. This facilitates the drive shaft 240 to achieve a limiting fit with the receiving tray 40 along its circumference, and the rotation of the drive shaft 240 can drive the receiving tray 40 to rotate. In other words, the aerosol generating device of this application embodiment expands the installation angle range between the installation channel 41a and the drive shaft 240, thus facilitating the installation of the atomizing medium component 100 on the host 200, thereby improving the assembly efficiency of the aerosol generating device.

[0116] Referring to Figures 4 and 7 to 9, in one embodiment, the housing 10 further has an exhaust channel 111a. One end of the exhaust channel 111a is connected to the heating area 10a, and the other end is connected to the outside. The aerosol generated in the heating area 10a can flow out through the exhaust channel 111a for user use. The aerosol generating device also includes a suction member 300, which is connected to the housing 10 and communicates with the other end of the exhaust channel 111a. The user can use the suction member 300 to suction the aerosol generated in the heating area 10a.

[0117] The housing 10 also has an air intake channel 112b (specifically, the first outer shell 11 may have an air intake channel 112b). External airflow enters the interior of the housing 10 through the air intake channel 112b and flows to the heating area 10a, thereby carrying the aerosol generated in the heating area 10a out through the air outlet channel 111a.

[0118] The atomizing medium assembly 100 is detachably disposed within the main unit 200. Specifically, referring to Figures 1 to 4, the main unit 200 includes a main housing 210 and an outer cover 230. An installation area 210a is formed on the main housing 210, and the heating assembly 220 and drive shaft 240 are both disposed within the installation area 210a. The atomizing medium assembly 100 is detachably disposed within the installation area 210a, and the open side of the installation area 210a is closed by the outer cover 230. During the suction process, external airflow can enter the installation area 210a through the gap between the main housing 210 and the outer cover 230, and then enter the interior of the housing 10 through the air intake channel 112b, thereby realizing the air intake of the aerosol generating device. The main housing 210 and the outer cover 230 can be connected by means such as magnetic connection, snap-fit, threaded connection, plug-in connection, or ultrasonic connection.

[0119] After the strip medium 20 is used up, the outer cover 230 can be removed from the main shell 210 to replace it with a new atomizing medium assembly 100. Of course, if the strip medium 20 and the shell 10 are detachable, the atomizing medium assembly 100 can be removed from the installation area 210a, the shell 10 can be opened, a new strip medium 20 can be replaced with the atomizing medium assembly 100, and then the atomizing medium assembly 100 can be installed in the installation area 210a.

[0120] The main unit 200 also includes a power supply assembly housed within the main housing 210. The heating assembly 220 is electrically connected to the power supply assembly and is used to heat the strip medium 20. The power supply assembly is permanently connected to the main housing 210 until it is depleted and can be discarded. Alternatively, the power supply assembly may be detachably connected to the main housing 210, meaning it can be removed and replaced, or it may be rechargeable (within or outside the aerosol generating device).

[0121] The manner in which the housing 10 forms the air outlet channel 111a is not limited. For example, referring to Figures 4, 6 to 9, the first outer shell 11 of the housing 10 includes a shell body 112 and a protrusion 111. A heating region 10a is defined between the shell body 112 and the second outer shell 12, and a strip medium 20 is disposed in the region between the shell body 112 and the second outer shell 12.

[0122] Specifically, in this embodiment, the air intake channel 112b can be disposed on the housing body 112.

[0123] The shape of the protrusion 111 is not limited. For example, it can be cylindrical, square, etc. For example, please refer to Figures 6 to 9. The protrusion 111 is cylindrical. The suction member 300 can be connected to the protrusion 111 at any angle in the circumferential direction, which facilitates user operation and improves the user experience.

[0124] The air outlet channel 111a is generally formed on the top side of the housing 10. The aerosol generated in the heating area 10a can be directly discharged through the protrusion 111. The protrusion 111 is closer to the user, and the aerosol can be transported to the outside from the air outlet channel 111a in a short time and used by the user.

[0125] The protrusion 111 facilitates the connection of the suction component 300 to the housing 10, thereby enabling the suction of aerosols.

[0126] The connection method between the suction component 300 and the protrusion 111 is not limited. For example, a detachable connection method such as plug-in or snap-fit ​​can be used.

[0127] As shown in Figures 4 and 7 to 9, in some embodiments, the atomizing medium assembly 100 includes a sealing ring 60, which is sandwiched between the protrusion 111 and the suction member 300. The material of the sealing ring 60 is not limited; for example, it can be silicone. By providing the sealing ring 60 between the suction member 300 and the protrusion 111, the sealing performance between the suction member 300 and the protrusion 111 is improved, reducing the possibility of aerosol overflowing through the gap between them, and also reducing the possibility of external airflow entering the suction member 300 through the gap between them. This allows the user to stably inhale aerosol through the suction member 300.

[0128] Please refer to Figures 3 to 8. In one embodiment, the housing 10 also has a storage space 10b and a storage space 10c, which are separated from each other. The storage tray 40 is disposed in the storage space 10c, and the storage tray 30 is disposed in the storage space 10b.

[0129] Specifically, please refer to Figures 7 and 8, where a storage space 10b and a receiving space 10c are defined between the shell body 112 and the second outer shell 12.

[0130] Storage space 10b and storage space 10c are separated. That is, by placing unused strip media 20 and used strip media 20 in two separate spaces, the unused strip media 20 and used strip media 20 are isolated from each other. This can, to some extent, reduce the possibility of cross-contamination of odors between the unused strip media 20 and used strip media 20. In addition, it can also prevent debris from used strip media 20 from sticking to unused strip media 20, thereby also preventing the generation of burnt smells to some extent.

[0131] In related technologies, the aerosol generation matrix strip will deform, harden, and delaminate after being atomized by the heating component. Furthermore, the aerosol generation device in the related technologies does not have a structure specifically for collecting the used aerosol generation matrix strip, which may further lead to the generation of debris from the used aerosol generation matrix strip.

[0132] The atomizing medium assembly 100 provided in this embodiment, by providing a dedicated storage space 10c within the housing 10 for storing the used strip medium 20, can reduce the generation of debris to a certain extent. Furthermore, by separating the storage space 10b from the storage space 10c, it can reduce the amount of debris entering the storage space 10b and adhering to the unused strip medium 20. In addition, by winding up the used strip medium 20 using the storage tray 40, the generation of debris can be further reduced. Simultaneously, by providing a dedicated storage space 10b within the housing 10 for storing the unused strip medium 20, a protective effect can be provided for the unused strip medium 20, resulting in a better user experience.

[0133] Please refer to Figure 9. In one embodiment, the housing 10 is provided with a drive connection hole 112a (specifically, the housing body 112 is provided with a drive connection hole 112a). The drive connection hole 112a is located on one axial side of the mounting channel 41a. The drive shaft 240 can pass through the drive connection hole 112a and extend into the mounting channel 41a, thus facilitating the drive shaft 240 to achieve a drive connection with the storage tray 40.

[0134] Please refer to Figures 2, 4, 5, 10 to 12. In one embodiment, the storage tray 40 includes an elastic element 42 and a tray body 41 having an installation channel 41a. The elastic element 42 is disposed on the side wall of the installation channel 41a, and the drive shaft 240 can be limited and engaged with the elastic element 42 along its circumference.

[0135] When the axial direction of the drive shaft 240 is not parallel to the axial direction of the mounting channel 41a, during the process of the drive shaft 240 extending into the mounting channel 41a, the end of the drive shaft 240 will squeeze the elastic member 42. Under the action of the squeezing force, the elastic member 42 will undergo elastic deformation and open in the radial direction of the mounting channel 41a, thereby avoiding the drive shaft 240.

[0136] In this embodiment, the elastic element 42 is the part of the storage tray 40 that can undergo elastic deformation. While facilitating the insertion of the drive shaft 240 into the installation channel 41a, the elastic element 42 can also achieve a limiting fit with the drive shaft 240 along the circumference of the drive shaft 240, thereby facilitating the drive shaft 240 to drive the storage tray 40 to rotate.

[0137] Please refer to Figures 10 to 12. In one embodiment, the elastic member 42 includes a connecting arm 421 disposed on the side wall of the mounting channel 41a and an elastic arm 422 connected to the connecting arm 421. The elastic arm 422 extends along the side wall of the mounting channel 41a and is spaced apart from the side wall of the mounting channel 41a to form a clearance gap 40a. During the process of the drive shaft 240 extending into the mounting channel 41a, the elastic arm 422 can be driven to undergo elastic deformation in the radial direction of the mounting channel 41a. When the drive shaft 240 is assembled in place, the elastic arm 422 restores its elastic deformation and is limited to the drive shaft 240 in the circumferential direction.

[0138] By providing the connecting arm 421, the installation of the elastic arm 422 on the installation channel 41a can be facilitated, and a clearance gap 40a can be formed between the elastic arm 422 and the side wall of the installation channel 41a.

[0139] The clearance 40a provides space for the elastic deformation of the elastic arm 422.

[0140] As the drive shaft 240 gradually extends into the mounting channel 41a, the angle between the axial direction of the drive shaft 240 and the axial direction of the mounting channel 41a becomes smaller and smaller until the two are parallel. The elastic arm 422 can recover at least part of its elastic deformation and fit against the side wall of the drive shaft 240.

[0141] It should be noted that after the axial direction of the drive shaft 240 is parallel to the axial direction of the mounting channel 41a, the elastic arm 422 does not fully recover its elastic deformation before the drive shaft 240 is in the assembled state. The drive shaft 240 can be rotated by a certain angle, and the elastic arm 422 continues to recover its elastic deformation during this process, so that the elastic arm 422 and the drive shaft 240 achieve a limiting fit along the circumference of the drive shaft 240.

[0142] Please refer to Figures 6 to 8 and Figures 10 to 12. In one embodiment, a portion of the sidewall of the drive shaft 240 is recessed to form a first limiting groove 240a. The elastic member 42 can be inserted into the first limiting groove 240a and be limited and engaged with the first limiting groove 240a along the circumference of the mounting channel 41a.

[0143] Specifically, please refer to Figure 5. The elastic arm 422 can be inserted into the first limiting groove 240a to achieve a limiting engagement with the drive shaft 240 in the circumferential direction.

[0144] After the drive shaft 240 extends into the mounting channel 41a and its axial direction is parallel to that of the mounting channel 41a, if the elastic arm 422 is in contact with the non-recessed area of ​​the drive shaft 240, the elastic arm 422 is still in an elastic deformation state. As the drive shaft 240 rotates until the elastic arm 422 is located outside the first limiting groove 240a, the elastic arm 422 continues to recover its elastic deformation, thus being able to engage within the first limiting groove 240a. Under the limiting action of the first limiting groove 240a, the drive shaft 240 continues to rotate, thereby transmitting a certain torsional force to the elastic arm 422. The elastic arm 422 then transmits this torsional force to the disc body 41 through the connecting arm 421, thereby driving the disc body 41 to rotate to wind the strip medium 20.

[0145] The limiting fit between the storage tray 40 and the drive shaft 240 is achieved through the matching structure between the first limiting groove 240a and the elastic element 42. This matching structure is relatively simple and does not require special alignment to install the atomizing medium assembly 100. As a result, the installation angle range of the storage tray 40 on the drive shaft 240 along its circumference is also expanded, which makes it easier for the user to replace the atomizing medium assembly 100.

[0146] Please refer to Figures 10 to 12. In one embodiment, there are multiple elastic elements 42, which are evenly spaced along the circumference of the mounting channel 41a. The number of first limiting grooves 240a corresponds one-to-one with the number of elastic elements 42.

[0147] It should be noted that, in the embodiments of this application, "multiple" refers to any number of two or more.

[0148] For example, in the embodiments of this application, there are two elastic elements 42 and two first limiting grooves 240a.

[0149] By setting multiple elastic elements 42 to cooperate with multiple first limiting grooves 240a, the reliability of the circumferential limiting cooperation between the drive shaft 240 and the storage tray 40 is improved.

[0150] Please refer to Figures 10 to 12. In one embodiment, the end of the drive shaft 240 is provided with a first guide surface 240b. Along a first direction, the first guide surface 240b gradually approaches the axis of the drive shaft 240. The first direction is the direction in which the drive shaft 240 extends into the mounting channel 41a when the axial direction of the drive shaft 240 is parallel to the axial direction of the mounting channel 41a.

[0151] For example, the first direction is the direction shown as d1 in Figures 11 and 12.

[0152] It should be noted that the first direction is the vector direction.

[0153] By setting the first guide surface 240b, when the drive shaft 240 extends into the mounting channel 41a, the storage tray 40 cooperates with the first guide surface 240b (specifically, the first guide surface 240b cooperates with the elastic arm 422), thereby facilitating the movement of the drive shaft 240 in the direction of extending into the mounting channel 41a.

[0154] Furthermore, as the drive shaft 240 extends into the mounting channel 41a, it can apply a pressing force to the storage tray 40 via the first guide surface 240b. Understandably, by transmitting the force through the surface, the pressure exerted on the storage tray 40 is reduced, thus lowering the likelihood of the drive shaft 240 damaging the storage tray 40.

[0155] Please refer to Figures 10 to 12. In one embodiment, the end of the elastic member 42 is provided with a second guide surface 422a. Along a first direction, the second guide surface 422a gradually approaches the axis of the mounting channel 41a. The first direction is the direction in which the drive shaft 240 extends into the mounting channel 41a when the axial direction of the drive shaft 240 is parallel to the axial direction of the mounting channel 41a.

[0156] Specifically, the elastic arm 422 of the elastic member 42 is provided with a second guide surface 422a at the end away from the connecting arm 421.

[0157] For example, the first direction is the direction shown as d1 in Figures 11 and 12.

[0158] It should be noted that the first direction is the vector direction.

[0159] By setting the second guide surface 422a, during the process of the drive shaft 240 extending into the mounting channel 41a, the second guide surface 422a cooperates with the drive shaft 240 (specifically, it can cooperate with the first guide surface 240b of the drive shaft 240). During the process of the drive shaft 240 extending into the mounting channel 41a, it can first touch the second guide surface 422a. The direction of the extrusion force applied by the drive shaft 240 to the elastic arm 422 is perpendicular to the second guide surface 422a, and the second guide surface 422a is inclined relative to the first direction. Thus, the extrusion force has a component force along the radial direction of the mounting channel 41a, which facilitates the drive shaft 240 to drive the elastic arm 422 to open along the radial direction of the mounting channel 41a, thereby facilitating the drive shaft 240 to continue moving in the direction of extending into the mounting channel 41a.

[0160] Please refer to Figures 3 to 5, 10 and 11. In one embodiment, along the circumferential direction of the mounting channel 41a, the elastic element 42 is limited to the side wall of the mounting channel 41a.

[0161] It is understandable that the maximum radial dimension of the installation channel 41a is greater than the maximum radial dimension of the drive shaft 240. When the drive shaft 240 is in the assembled state, during the process of its rotation and driving the storage tray 40 to rotate, the elastic element 42 may undergo circumferential elastic deformation after being subjected to circumferential torsional force.

[0162] In this embodiment, the elastic member 42 is limited in the circumferential direction by the side wall of the mounting channel 41a. The elastic member 42 will not undergo elastic deformation in the circumferential direction of the mounting channel 41a. This improves the structural stability of the elastic member 42 in the circumferential direction of the mounting channel 41a, and makes it easier for the drive shaft 240 to drive the disk body 41 to rotate through the elastic member 42.

[0163] Please refer to Figures 3 to 5, 10, 11 and 13. In one embodiment, the atomizing medium assembly 100 further includes a fixing member 50. At least a portion of the fixing member 50 is disposed within the mounting channel 41a, and along the circumference of the mounting channel 41a, the fixing member 50 is respectively limited and engaged with the elastic member 42 and the side wall of the mounting channel 41a.

[0164] In this embodiment, the elastic element 42 and the side wall of the mounting channel 41a are circumferentially limited and engaged by the fastener 50.

[0165] In other words, based on the storage tray 40, the elastic arm 422 of the elastic member 42 will not form a direct contact relationship with the side wall of the installation channel 41a along the circumferential sides of the installation channel 41a, thus facilitating the demolding of the elastic member 42.

[0166] Please refer to Figures 5, 10, 11 and 13. In one embodiment, the fixing member 50 is provided with a first limiting surface 50a and a second limiting surface 50b along its circumference, and the elastic member 42 is sandwiched between the first limiting surface 50a and the second limiting surface 50b.

[0167] The formation of the first limiting surface 50a and the second limiting surface 50b is not limited. For example, as shown in FIG13, a groove is formed on the fixing member 50, and the sidewalls of the groove along the two sides of the fixing member 50 in the circumferential direction are the first limiting surface 50a and the second limiting surface 50b, respectively.

[0168] The first limiting surface 50a and the second limiting surface 50b can respectively limit the elastic member 42 on both sides of the circumferential direction of the installation channel 41a, so that the fixing member 50 can achieve limiting cooperation with the elastic member 42 along its circumferential direction.

[0169] Please refer to Figures 5, 10, 11 and 13. In one embodiment, one of the outer side wall of the fastener 50 and the side wall of the mounting channel 41a is provided with a second limiting groove 52a, and the other is provided with a limiting protrusion 41b. At least a portion of the limiting protrusion 41b extends into the second limiting groove 52a and engages with the second limiting groove 52a in a circumferential limiting manner along the mounting channel 41a.

[0170] Specifically, the outer wall of the fastener 50 may be provided with a second limiting groove 52a, and the side wall of the mounting channel 41a may be provided with a limiting protrusion 41b; or the outer wall of the fastener 50 may be provided with a limiting protrusion 41b, and the side wall of the mounting channel 41a may be provided with a second limiting groove 52a.

[0171] The limiting protrusion 41b and the second limiting groove 52a achieve a snap-fit ​​limiting, so that the fixing member 50 achieves a limiting engagement with the side wall of the installation channel 41a along its circumference.

[0172] The structure of the limiting protrusion 41b and the second limiting groove 52a engaging and limiting is relatively simple. Thus, the structure of the storage tray 40 and the fixing member 50 is also relatively simple, which is convenient for production.

[0173] Please refer to Figures 5, 10 to 13. In one embodiment, the mounting channel 41a extends through the storage tray 40, the drive shaft 240 extends into the mounting channel 41a through one axial end, and the fastener 50 is disposed in the mounting channel 41a through the other axial end.

[0174] Understandably, the side wall of the installation channel 41a is provided with a limiting protrusion 41b and an elastic element 42.

[0175] By configuring the mounting channel 41a to extend through both ends of the storage tray 40 along its axial direction, the storage tray 40 can be ejected from the mold along both ends of the mounting channel 41a during injection molding, thereby injection molding the elastic element 42 and the limiting protrusion 41b. In other words, the storage tray 40 of this embodiment reduces the difficulty of demolding the storage tray 40, thus facilitating the production of the storage tray 40.

[0176] Furthermore, since the drive shaft 240 needs to extend into the mounting channel 41a from one end of the mounting channel 41a, and the other end of the mounting channel 41a is also open in the axial direction, it facilitates the installation of the fastener 50.

[0177] The specific structure of the fastener 50 is not limited. For example, please refer to Figures 5, 10 to 13. In one embodiment, the fastener 50 includes a top cover 51 and side panels 52 surrounding the outer periphery of the top cover 51. Along the circumference of the mounting channel 41a, the side panels 52 respectively limit the engagement with the elastic member 42 and the side wall of the mounting channel 41a, and the top cover 51 seals the other end of the mounting channel 41a.

[0178] As shown in Figure 13, in this embodiment, the side panel 52 is provided with a first limiting surface 50a, a second limiting surface 50b, and a second limiting groove 52a.

[0179] The top cover 51 can effectively seal at least a portion of one end of the axial direction of the installation channel 41a, thereby reducing the possibility of external debris and other impurities entering the housing 10 through the installation channel 41a. This reduces the probability that the parts inside the housing 10 will malfunction due to interference from external debris (e.g., debris prevents the strip medium 20 from moving), thus improving the reliability of the aerosol generating device.

[0180] Furthermore, when the airtightness requirement inside the housing 10 is high, the top cover 51 can seal at least a portion of one axial end of the mounting channel 41a, thereby enhancing the sealing performance inside the housing 10.

[0181] Please refer to Figures 5, 10 to 13. In one embodiment, the fastener 50 is provided with a receiving groove 50c, and at least a portion of the drive shaft 240 is located within the receiving groove 50c.

[0182] Specifically, as shown in Figure 13, the top cover 51 and the side panel 52 form a receiving groove 50c.

[0183] It is understood that at least a portion of the drive shaft 240 extending into the mounting channel 41a can be accommodated by the receiving groove 50c. That is, along the radial direction of the mounting channel 41a, there is an overlap between the drive shaft 240 and the fixing member 50.

[0184] By providing the receiving groove 50c, the dimension of the fastener 50 extending into the mounting channel 41a can be longer without interfering with the drive shaft 240. Thus, along the axial direction of the mounting channel 41a, the dimension of the portion of the fastener 50 used for limiting and engaging with the elastic member 42 and the sidewall of the mounting channel 41a is larger, thereby improving the reliability of the limiting and engaging structure between the fastener 50 and the elastic member 42 and the sidewall of the mounting channel 41a.

[0185] Please refer to Figures 1, 14 to 23. This application provides an aerosol generating device, which includes a main unit 200 and an atomizing medium assembly 100. The main unit 200 includes a main shell 210 and a heating assembly 220. The main shell 210 has an installation area 210a extending along a second direction. The two ends of the installation area 210a along the second direction are a first end 210b and a second end 210c, respectively. The heating assembly 220 is disposed within the installation area 210a and is located close to the first end 210b along the second direction. The atomizing medium assembly 100 includes a strip medium 20 and a shell 10 having a heating area 10a. A portion of the strip medium 20 is disposed within the heating area 10a. The two ends of the shell 10 along the second direction are an assembly end 10m and a mating end 10n, respectively. The main shell 210 has a first mating portion 210d, and the shell 10 has a second mating portion 10x. When the assembly end 10m rotates about the mating end 10n towards the installation area 210a, the first mating part 210d and the second mating part 10x can interfere to limit the rotation of the assembly end 10m and keep the heating component 220 separated from the strip medium 20. When the assembly end 10m abuts against the second end 210c, and the mating end 10n rotates about the assembly end 10m towards the installation area 210a, the first mating part 210d and the second mating part 10x cooperate to allow the housing 10 to be assembled into the installation area 210a, and at least a portion of the heating component 220 extends into the heating area 10a to heat the strip medium 20. The main unit 200 of the aerosol generating device in this embodiment is reusable, that is, one main unit 200 of the aerosol generating device can be matched with multiple atomizing medium components 100, thereby reducing the user's operating costs and being environmentally friendly.

[0186] The specific direction of the second direction is not limited. For example, the second direction is the direction shown as d2 in Figures 14 to 16, 18, and 20.

[0187] The heating component 220 is used to heat the strip medium 20 to generate an aerosol. The heating method of the heating component 220 is not limited. Exemplarily, in an embodiment of this application, the heating method may be contact heating.

[0188] It should be noted that contact heating refers to a heating method in which heat is transferred between the heating element 220 and the strip medium 20 through contact. The heating element 220 may include, for example, a resistor module that converts electrical energy into heat energy, which can then be used to heat the strip medium 20.

[0189] The heating component 220 approaches the first end 210b along the second direction. That is, along the second direction, the distance between the heating component 220 and the first end 210b is less than the distance between the heating component 220 and the second end 210c.

[0190] The main unit 200 also includes a power supply assembly housed within the main housing 210. The heating assembly 220 is electrically connected to the power supply assembly and is used to heat the strip medium 20. The power supply assembly is permanently connected to the main housing 210 until it is depleted and can be discarded. Alternatively, the power supply assembly may be detachably connected to the main housing 210, meaning it can be removed and replaced, or it may be rechargeable (within or outside the aerosol generating device).

[0191] Referring to Figures 1 and 14, the main unit 200 also includes an outer cover 230. The atomizing medium assembly 100 is detachably disposed within the mounting area 210a, and the outer cover 230 closes the open side of the mounting area 210a. During the suction process, external airflow can enter the mounting area 210a through the gap between the main housing 210 and the outer cover 230, thereby entering the interior of the housing 10 to achieve air intake for the aerosol generating device. The main housing 210 and the outer cover 230 can be connected by means of magnetic attraction, snap-fit, threaded connection, plug-in, or ultrasonic connection, for example.

[0192] The specific structure of the housing 10 is not limited, and it can be used to contain the strip medium 20. For example, referring to Figures 22 and 23, the housing 10 includes a first outer shell 11 and a second outer shell 12, which are disposed opposite to each other and define a heating zone 10a. The strip medium 20 can be disposed in the area between the first outer shell 11 and the second outer shell 12. The first outer shell 11 and the second outer shell 12 can be detachably connected, so that after the strip medium 20 is used, a new strip medium 20 can be replaced, and the housing 10 can be reused, thereby reducing the user's operating costs.

[0193] The strip medium 20 is a flexible strip structure with a certain width and thickness, but its length can be extended and bent according to actual conditions.

[0194] The surface of the strip medium 20 is coated or the interior is infiltrated or embedded with an aerosol generating matrix for generating aerosols. The aerosol generating matrix includes, but is not limited to, pharmaceuticals or nicotine-containing materials.

[0195] For example, the strip medium 20 may include a base strip and an aerosol generating matrix that is alternately coated on the base strip.

[0196] The base tape can be any strip that can withstand heating temperatures, possesses a certain degree of flexibility, and can be unwound and rewound, such as paper strips, polymer strips, metal base tapes, graphite base tapes, etc. The base tape can also be a metal mesh, which can be formed by weaving metal wires or by setting multiple through holes in a metal sheet.

[0197] Unwinding refers to the process of peeling the outer and inner layers of a rolled substrate radially. Rewinding refers to the method of taking continuous products into winding using a roll, reel, or similar device.

[0198] A portion of the strip medium 20 is disposed within the heating zone 10a. That is, a portion of the strip medium 20 can move into the heating zone 10a and be heated to generate an aerosol. The strip medium 20 can continuously pass through the heating zone 10a, and the aerosol-generating matrix on the portion of the strip medium 20 currently within the heating zone 10a can generate an aerosol. It is understood that once the entire strip medium 20 has passed through the heating zone 10a, it indicates that the strip medium 20 has been used up.

[0199] The housing 10 can store and contain the strip medium 20. That is, the unused strip medium 20 is stored in the housing 10. During the use of the atomizing medium assembly 100, the unused strip medium 20 passes through the heating zone 10a in sequence and is heated and used. The used strip medium 20 is still stored in the housing 10 to prevent the atomized medium residue from falling into the main unit 200 and causing pollution.

[0200] After the strip medium 20 is used up, the outer cover 230 can be removed from the main housing 210 to replace it with a new atomizing medium assembly 100. Alternatively, if the strip medium 20 and the housing 10 are detachable, the atomizing medium assembly 100 can be removed from the installation area 210a, the housing 10 opened, a new strip medium 20 replaced, and then the atomizing medium assembly 100 installed back into the installation area 210a. The main unit 200 of the aerosol generating device in this embodiment is reusable; that is, one main unit 200 of the aerosol generating device can be matched with multiple atomizing medium assemblies 100, thereby reducing user costs and being environmentally friendly.

[0201] In other words, the aerosol generating device of this application embodiment allows for the replacement of the atomizing medium component 100 during use; that is, the user needs to independently assemble the atomizing medium component 100 into the installation area 210a. Generally, based on operating habits, there are two assembly methods to achieve the assembly of the atomizing medium component 100 into the installation area 210a.

[0202] The first assembly method: Referring to Figures 14 and 15, position the mating end 10n against the first end 210b, then rotate the assembly end 10m around the mating end 10n towards the installation area 210a, thereby assembling the atomizing medium assembly 100 entirely within the installation area 210a. It is understood that because the heating component 220 is relatively close to the first end 210b, when assembling the atomizing medium assembly 100 using this method, the assembly end 10m only needs to rotate a small angle around the mating end 10n for the heating component 220 to insert into the heating area 10a. Furthermore, since the rotation angle of the assembly end 10m around the mating end 10n is small, the tilt angle of the heating component 220 when inserted into the heating area 10a is relatively large. If the assembly end 10m continues to be rotated in this direction, the assembly end 10m will need to be rotated by a larger angle to allow the atomizing medium assembly 100 to be fully assembled in the installation area 210a. The relative displacement of the heating assembly 220 in the heating area 10a will also be large, which will cause the strip medium 20 to be squeezed into the heating area 10a, resulting in problems such as deformation or breakage of the strip medium 20.

[0203] The second assembly method: Referring to Figures 14 and 15, position the assembly end 10m against the second end 210c. Then, rotate the mating end 10n around the assembly end 10m towards the installation area 210a, thereby assembling the atomizing medium assembly 100 entirely within the installation area 210a. It is understandable that, because the heating component 220 is relatively far from the second end 210c, when assembling the atomizing medium assembly 100 using this method, the mating end 10n will rotate a significant angle around the assembly end 10m before the heating component 220 is inserted into the heating area 10a. Furthermore, because the mating end 10n has already rotated a significant angle, the heating component 220 will also be inserted into the heating area 10a at a relatively small tilt angle. If the mating end 10n continues to rotate in this direction, the mating end 10n only needs to rotate a small angle to allow the atomizing medium assembly 100 to be fully assembled in the installation area 210a. The relative displacement of the heating assembly 220 in the heating area 10a is also small, which helps to reduce the probability of the heating assembly 220 squeezing the strip medium 20 in the heating area 10a and causing the strip medium 20 to deform or break.

[0204] In other words, compared with the first assembly method, the second assembly method for assembling the atomizing medium component 100 reduces the likelihood of the strip medium 20 being squeezed by the heating component 220, thereby reducing the probability of the strip medium 20 deforming or breaking.

[0205] Based on this, in the aerosol generating apparatus of this application embodiment, during the process of the mating end 10n abutting against the first end 210b and the assembly end 10m rotating around the mating end 10n towards the direction of entering the installation area 210a, the first mating part 210d and the second mating part 10x can form interference to limit the rotation of the assembly end 10m and keep the heating component 220 and the strip medium 20 in a separated state. That is, after the assembly end 10m rotates around the mating end 10n to the interference position of the first mating part 210d and the second mating part 10x, the assembly end 10m can no longer continue to rotate around the mating end 10n towards the direction of entering the installation area 210a, and at the same time the strip medium 20 and the heating component 220 are in a separated state, and the heating component 220 will not squeeze the strip medium 20. During the process of the assembly end 10m abutting against the second end 210c and the mating end 10n rotating around the assembly end 10m toward the installation area 210a, the first mating part 210d and the second mating part 10x engage to allow the housing 10 to be assembled into the installation area 210a, and at least a portion of the heating component 220 extends into the heating area 10a to heat the strip medium 20. That is, during the rotation of the mating end 10n around the assembly end 10m, the first mating part 210d and the second mating part 10x do not interfere with each other, thereby allowing the atomizing medium assembly 100 to be assembled into the installation area 210a. Therefore, during the assembly of the atomizing medium assembly 100 into the installation area 210a, the heating component 220 can be inserted into the heating area 10a at a small tilt angle, and the relative displacement within the heating area 10a is small. This helps to reduce the probability of the heating component 220 squeezing the strip medium 20 within the heating area 10a and causing deformation or breakage of the strip medium 20.

[0206] In other words, the aerosol generating device of this application embodiment can avoid the user from assembling the atomizing medium component 100 using the first assembly method, and can assemble the atomizing medium component 100 using the second assembly method. In this way, the probability of the strip medium 20 being deformed or broken is reduced.

[0207] The positions of the first mating part 210d on the main shell 210 and the second mating part 10x on the housing 10 are not limited. For example, referring to Figures 14 to 16, 22, and 23, in one embodiment, the first mating part 210d is provided on at least one sidewall of the mounting area 210a along a third direction, and the second mating part 10x is provided on at least one sidewall of the housing 10 along a third direction. The first mating part 210d and the second mating part 10x are mated in a one-to-one correspondence; wherein the third direction intersects with the second direction.

[0208] The specific direction of the third direction is not limited. For example, the third direction is the direction shown as d3 in Figures 14 and 15.

[0209] The third direction can be orthogonal to the second direction.

[0210] A first mating portion 210d is provided on at least one side wall of the mounting area 210a along a third direction. That is, the first mating portion 210d may be provided on one side of the mounting area 210a along a third direction, and a second mating portion 10x may be provided on the side of the housing 10 corresponding to the first mating portion 210d; or the first mating portion 210d may be provided on both opposite sides of the mounting area 210a along a third direction, and the second mating portion 10x may be provided on both opposite sides of the housing 10 along a third direction.

[0211] The first mating part 210d is disposed within the mounting area 210a. After the atomizing medium assembly 100 and the main shell 210 are assembled, both the first mating part 210d and the second mating part 10x can be hidden within the mounting area 210a, i.e., they will not protrude from the outside of the main shell 210. This reduces the impact of the first mating part 210d and the second mating part 10x on the installation of other components of the aerosol generating device. For example, referring to Figures 1 and 14, when the aerosol generating device also includes the aforementioned outer shell, the first mating part 210d and the second mating part 10x will not affect the installation between the outer shell and the main shell 210.

[0212] Furthermore, the first mating part 210d can be easily installed on both sides of the installation area 210a along the third direction.

[0213] It should be noted that the types of the first mating part 210d and the second mating part 10x are not limited. For example, please refer to Figures 14 to 16 and Figures 20 to 23. In one embodiment, one of the first mating part 210d and the second mating part 10x is a track boss, and the other is a track groove. During the process of the mating end 10n abutting against the first end 210b and the assembly end 10m rotating about the mating end 10n in the direction of entering the installation area 210a, the sidewall of the track boss and the sidewall of the track groove can interfere with each other. During the process of the assembly end 10m abutting against the second end 210c and the mating end 10n rotating about the assembly end 10m in the direction of entering the installation area 210a, the track boss can move freely about the assembly end 10m within the track groove.

[0214] Specifically, in the embodiments of this application, the first mating part 210d is used as a track boss and the second mating part 10x is used as a track groove for example.

[0215] The dimension of the track groove along the second direction is slightly larger than that of the track boss, so that the track boss can move within the track groove at a certain tilt angle.

[0216] The track boss is positioned close to the first end 210b. That is, the distance between the track boss and the first end 210b is less than the distance between the track boss and the second end 210c.

[0217] Referring to Figures 14 and 15, during the process of the mating end 10n abutting against the first end 210b and the assembly end 10m rotating around the mating end 10n in the direction of entering the installation area 210a, the tilt angle between the track boss and the track groove is relatively large, which makes it impossible for the track boss to completely enter the track groove. Thus, interference can be formed between the two.

[0218] Referring to Figures 14 and 16, as the assembly end 10m abuts against the second end 210c, and the mating end 10n rotates around the assembly end 10m toward the direction of entering the installation area 210a, after rotating to a position where the track groove and the track boss are close together, the tilt angle between the track groove and the track boss is relatively small, and the track boss can gradually enter the track groove. The mating end 10n continues to rotate around the assembly end 10m toward the direction of entering the installation area 210a, and the track boss can move within the track groove.

[0219] It is understandable that once the location and specific dimensions of one of the trajectory boss and trajectory slot are determined, the location and specific dimensions of the other can be obtained through simulation.

[0220] The first mating part 210d and the second mating part 10x are mated using a track boss and a track groove structure, which makes the structure of the first mating part 210d and the second mating part 10x relatively simple and easy to implement.

[0221] Please refer to Figures 17, 20 and 21. In one embodiment, the first mating part 210d is a track boss. Along the second direction, the distance between the track boss and the first end 210b is less than the distance between the heating component 220 and the first end 210b, and the distance between the side of the track boss facing the first end 210b and the side of the heating component 220 facing the first end 210b is not less than 4 mm.

[0222] The distance between the side of the track boss facing the first end 210b and the side of the heating assembly 220 facing the first end 210b is shown as L1 in Figure 21. L1 is not less than 4 mm. For example, it is 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0223] The specific direction of the fourth direction is not limited. For example, the fourth direction is the direction shown as d4 in Figures 14 and 20.

[0224] Referring to Figures 14 and 15, in the first assembly method, the rotation center of the assembly end 10m rotating around the mating end 10n is close to the first end 210b. The atomizing medium component 100, the rotation center, and the wall of the installation area 210a essentially form a triangle. Since the track boss is closer to the first end 210b than the heating component 220, the interference position of the track boss and the track groove is also closer to the first end 210b than the heating component 220. After the track boss and the track groove are in the interference position, the space at the position of the heating component 220 is relatively large. This helps to reduce the size of the heating component 220 inserted into the heating area 10a, and may even prevent the heating component 220 from entering the heating area 10a, thereby reducing the probability of the heating component 220 squeezing the strip medium 20 in the heating area 10a.

[0225] Please refer to Figures 17, 20 and 21. In one embodiment, the first mating part 210d is a track boss, the extension direction of the heating component 220 is the fourth direction, and along the fourth direction, the ratio of the size of the track boss to the size of the wall surface of the heating component 220 protruding from the mounting area 210a is not less than 0.7.

[0226] The specific direction of the fourth direction is not limited. For example, the fourth direction is the direction shown as d4 in Figures 14 and 20.

[0227] The dimensions of the track boss are shown as L2 in Figure 21, and the dimensions of the heating component 220 protruding from the wall of the mounting area 210a are shown as L3 in Figure 21. The ratio of L2 to L3 is not less than 0.7. For example, it is 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, etc.

[0228] The ratio of L2 to L3 is not less than 0.7, and the track boss has sufficient size relative to the portion of the heating component 220 protruding from the wall of the mounting area 210a. Referring to Figures 14 and 15, in the first assembly method, when the assembly end 10m rotates around the mating end 10n and the track boss and track groove are in the interference position, the rotation angle generated by the assembly end 10m around the mating end 10n will not be too large. As a result, sufficient space can be formed between the housing 10 and the wall of the mounting area 210a to accommodate the heating component 220, which helps to reduce the size of the heating component 220 inserted into the heating area 10a, and may even prevent the heating component 220 from entering the heating area 10a, thereby reducing the probability of the heating component 220 squeezing the strip medium 20 in the heating area 10a.

[0229] Please refer to Figures 14 to 16. In one embodiment, the sidewalls of the track boss and the track groove on opposite sides of the second direction are both arc-shaped. When the housing 10 is assembled in the mounting area 210a, the sidewalls of the track boss and the track groove on opposite sides of the second direction are both bent away from the second end 210c.

[0230] The sidewalls of the track boss and the track groove, both located on opposite sides along the second direction, curve away from the second end 210c. That is, the middle region of the arc-shaped sidewall of the track boss is closer to the first end 210b, and the two ends are closer to the second end 210c. The arc-shaped sidewall of the track groove is similarly curved.

[0231] Please refer to Figures 14 and 16. In the second assembly method, the assembly end 10m abuts against the second end 210c, that is, the track groove or track boss also rotates around the second end 210c.

[0232] In this embodiment, the center of the arc-shaped sidewall of the trajectory boss and the center of the arc-shaped sidewall of the trajectory groove can both be located at the second end 210c. Thus, when the atomizing medium assembly 100 is assembled using the second assembly method, the trajectory boss can move within the trajectory groove. When the atomizing medium assembly 100 is assembled using the first assembly method, the sidewall of the trajectory boss and the sidewall of the trajectory groove will interfere with each other.

[0233] In other embodiments, the sidewalls of the track boss and the track groove can also be planar structures. It is only necessary to ensure that when the atomizing medium assembly 100 is assembled using the first assembly method, the sidewalls of the track boss and the track groove can interfere with each other, and when they are in the interference position, the heating assembly 220 is separated from the strip medium 20 in the heating area 10a; and when the atomizing medium assembly 100 is assembled using the second assembly method, the track boss can move within the track groove so that the atomizing medium assembly 100 can be assembled within the installation area 210a.

[0234] Please refer to Figures 17 to 19. In one embodiment, with the housing 10 assembled in the mounting area 210a, the strip medium 20 in the heating area 10a is located on the side of the heating assembly 220 facing the first end 210b.

[0235] Referring to Figures 14 and 16, it can be understood that, since the strip medium 20 within the heating region 10a needs to be located on the side of the heating assembly 220 facing the first end 210b, when assembling the atomizing medium assembly 100 using the second assembly method, even if the heating assembly 220 contacts the strip medium 20 first, the top of the heating assembly 220 is pressed against the width surface of the strip medium 20, meaning it will not touch the thickness surface of the strip medium 20. Since the width dimension is greater than the thickness dimension, after the heating assembly 220 is pressed against the width surface, the contact area between the strip medium 20 and the heating assembly 220 is larger, resulting in a smaller pressure drop. This reduces the probability of the strip medium 20 being squeezed by the heating assembly 220 and experiencing deformation or breakage.

[0236] Furthermore, after the heating component 220 is pressed onto the width surface of the strip medium 20, as the mating end 10n continues to rotate around the assembly end 10m, the heating component 220 can push the strip medium 20 in the heating area 10a to move a certain distance along the second direction toward the side closer to the first end 210b, so that the strip medium 20 can be stably pressed onto the heating component 220, thereby enabling the heating component 220 to better heat the strip medium 20.

[0237] Please refer to Figures 14 to 16. In one embodiment, the thickness direction of the heating component 220 is parallel to the second direction.

[0238] It should be noted that the dimensions of different parts in the three directions are different in the same absolute coordinate system. Generally, the length, width and thickness of an object are determined according to the dimensions of the object extending in the three directions, with length > width > thickness.

[0239] That is, the thickness direction is the direction in which the size of the heating component 220 is the smallest. By setting the thickness direction of the heating component 220 to be parallel to the second direction, the size of the heating component 220 in the second direction is smaller. This reduces the probability of it squeezing the strip medium 20 in the heating area 10a and causing the strip medium 20 to deform or break.

[0240] Please refer to Figures 14 to 16. In one embodiment, the thickness direction of the strip medium 20 located in the heating region 10a is parallel to the second direction.

[0241] The thickness direction is the direction in which the size of the strip medium 20 is the smallest. By setting the thickness direction of the strip medium 20 in the heating region 10a to be parallel to the second direction, the size of the strip medium 20 in the heating region 10a in the second direction is smaller. This reduces the probability that the strip medium 20 in the heating region 10a will be squeezed by the heating component 220 and deform or break.

[0242] Please refer to Figures 22 and 23. In one embodiment, the housing 10 further has a storage space 10b and a receiving space 10c, which are separated. The atomizing medium assembly 100 also includes a storage disk 30 disposed in the storage space 10b and a receiving disk 40 disposed in the receiving space 10c. The storage disk 30 is used to wind the strip medium 20. The strip medium 20 can be unwound from the storage disk 30 and wound onto the receiving disk 40 after passing through the heating area 10a.

[0243] Specifically, please refer to Figure 23. The housing 10 includes a first outer shell 11 and a second outer shell 12. The first outer shell 11 includes a shell body 112 and a protrusion 111. The shell body 112 and the second outer shell 12 define a storage space 10b and a receiving space 10c.

[0244] Storage space 10b and storage space 10c are separated. That is, by placing unused strip media 20 and used strip media 20 in two separate spaces, the unused strip media 20 and used strip media 20 are isolated from each other. This can, to some extent, reduce the possibility of cross-contamination of odors between the unused strip media 20 and used strip media 20. In addition, it can also prevent debris from used strip media 20 from sticking to unused strip media 20, thereby preventing the generation of burnt smells and other odors to some extent.

[0245] By setting up the storage disk 30, the storage disk 30 can be rotated, which facilitates the unwinding of the strip medium 20 from the storage disk 30 and reduces the friction between the strip medium 20 and the housing 10 during the unwinding process.

[0246] By setting up a storage tray 40, the storage tray 40 can be rotated, which helps to wind the strip medium 20 onto the storage tray 40 and reduce the friction between the strip medium 20 and the housing 10 during the winding process.

[0247] In related technologies, the aerosol generation matrix strip will deform, harden, and delaminate after being atomized by the heating component. Furthermore, the aerosol generation device in the related technologies does not have a structure specifically for collecting the used aerosol generation matrix strip, which may further lead to the generation of debris from the used aerosol generation matrix strip.

[0248] The atomizing medium assembly 100 provided in this embodiment, by providing a dedicated storage space 10c within the housing 10 for storing the used strip medium 20, can reduce the generation of debris to a certain extent. Furthermore, by separating the storage space 10b from the storage space 10c, the amount of debris entering the storage space 10b and adhering to the unused strip medium 20 can be reduced. In addition, by providing a storage tray 40 within the storage space 10c for winding up the used strip medium 20, the generation of debris can be further reduced. Simultaneously, by providing a dedicated storage space 10b within the housing 10 for storing the unused strip medium 20, a protective effect is provided for the unused strip medium 20, resulting in a better user experience.

[0249] Please refer to Figures 14, 15, 22 and 23. In one embodiment, the host 200 further includes a drive shaft 240. When the housing 10 is assembled in the mounting area 210a, at least a portion of the drive shaft 240 extends into the storage space 10c and is driven to connect with the storage tray 40.

[0250] The drive shaft 240 is located in the installation area 210a. The housing 10 is provided with a drive connection hole 112a (specifically, the housing body 112 is provided with a drive connection hole 112a). The drive shaft 240 passes through the drive connection hole 112a and is driven to connect with the storage tray 40. The drive shaft 240 rotates to drive the storage tray 40 to rotate. Through the rotation of the storage tray 40, the used strip medium 20 can be wound onto the storage tray 40. At the same time, the storage tray 30 follows the storage tray 40 and moves accordingly, so that the strip medium 20 stored on the storage tray 30 is unwound.

[0251] Please refer to Figures 14, 17 to 19, 22, and 23. The housing 10 also has an exhaust channel 111a. One end of the exhaust channel 111a is connected to the heating area 10a, and the other end is connected to the outside. The aerosol generated in the heating area 10a can flow out through the exhaust channel 111a for user use. The aerosol generating device also includes a suction component 300, which is connected to the housing 10 and communicates with the other end of the exhaust channel 111a. The user can use the suction component 300 to suction the aerosol generated in the heating area 10a.

[0252] The manner in which the housing 10 forms the air outlet channel 111a is not limited. For example, referring to Figures 22 and 23, the first outer shell 11 of the housing 10 includes a shell body 112 and a protrusion 111. A heating region 10a is defined between the shell body 112 and the second outer shell 12, and a strip medium 20 is disposed in the region between the shell body 112 and the second outer shell 12.

[0253] The shape of the protrusion 111 is not limited. For example, it can be cylindrical, square, etc. For example, please refer to Figures 22 and 23. The protrusion 111 is cylindrical. The suction member 300 can be connected to the protrusion 111 at any angle in the circumferential direction, which facilitates user operation and improves the user experience.

[0254] The air outlet channel 111a is generally formed on the top side of the housing 10. The aerosol generated in the heating area 10a can be directly discharged through the protrusion 111. The protrusion 111 is closer to the user, and the aerosol can be transported to the outside from the air outlet channel 111a in a short time and used by the user.

[0255] The protrusion 111 facilitates the connection of the suction component 300 to the housing 10, thereby enabling the suction of aerosols.

[0256] The connection method between the suction component 300 and the protrusion 111 is not limited. For example, a detachable connection method such as plug-in or snap-fit ​​can be used.

[0257] Please refer to Figures 28 to 33. This application embodiment provides an atomizing medium assembly. The atomizing medium assembly 100 includes a housing 10 and a strip medium 20. The housing 10 has a heating region 10a, an air outlet channel 111a, and a negative pressure air channel 111b. The two ends of the air outlet channel 111a are respectively connected to the heating region 10a and the outside. One end of the negative pressure air channel 111b is connected to the air outlet channel 111a, and the other end is connected to the negative pressure sensor 260 of the aerosol generating device. The strip medium 20 can be partially moved into the heating region 10a and heated to generate aerosol. In a plane perpendicular to the axis of the air outlet channel 111a, the projection of the axis of the negative pressure air channel 111b has a first angle with the thickness direction of the housing 10, and the first angle is not 0°. The atomizing medium component 100 provided in this application embodiment has the advantages of rapid heating and high consistency of atomized aerosol taste. Moreover, the atomizing medium component 100 provided in this application embodiment can provide more inhalation ports than the prior art, reducing the number of times users need to replace the atomizing medium and providing a better user experience.

[0258] Please refer to Figures 1, 24 to 33. This application provides an aerosol generating device. The aerosol generating device includes a main unit 200, a suction component 300, and an atomizing medium assembly 100 according to any embodiment of this application. The main unit 200 includes a negative pressure sensor 260; the atomizing medium assembly 100 is detachably mounted on the main unit 200, and one end of the negative pressure airway 111b away from the outlet airway 111a is connected to the negative pressure sensor 260; the suction component 300 is connected to the housing 10 and communicates with the outlet airway 111a. This aerosol generating device can be activated by the negative pressure sensor 260. Compared to existing heated non-combustible appliances that require an additional button for activation, this reduces operational complexity. Users can directly activate the aerosol generating device by suction, simplifying the usage steps and improving the user experience.

[0259] The specific structure of the housing 10 is not limited, and it can be used to contain the strip medium 20. For example, referring to Figures 27, 28, and 32, the housing 10 includes a first outer shell 11 and a second outer shell 12, which are disposed opposite to each other and define a heating zone 10a. The strip medium 20 can be disposed in the area between the first outer shell 11 and the second outer shell 12. The first outer shell 11 and the second outer shell 12 can be detachably connected, so that after the strip medium 20 is used, a new strip medium 20 can be replaced, and the housing 10 can be reused, thereby reducing the user's operating costs.

[0260] The strip medium 20 is a flexible strip structure with a certain width and thickness, but its length can be extended and bent according to actual conditions.

[0261] The surface of the strip medium 20 is coated or the interior is infiltrated or embedded with an aerosol generating matrix for generating aerosols. The aerosol generating matrix includes, but is not limited to, pharmaceuticals or nicotine-containing materials.

[0262] For example, the strip medium 20 may include a base strip and an aerosol generating matrix that is alternately coated on the base strip.

[0263] The base tape can be any strip that can withstand heating temperatures, possesses a certain degree of flexibility, and can be unwound and rewound, such as paper strips, polymer strips, metal base tapes, graphite base tapes, etc. The base tape can also be a metal mesh, which can be formed by weaving metal wires or by setting multiple through holes in a metal sheet.

[0264] Unwinding refers to the process of peeling the outer and inner layers of a rolled substrate radially. Rewinding refers to the method of taking continuous products into winding using a roll, reel, or similar device.

[0265] A portion of the strip medium 20 can move into the heating zone 10a and be heated to generate an aerosol. That is, the strip medium 20 can continuously pass through the heating zone 10a, and the aerosol-generating matrix on the portion of the strip medium 20 currently within the heating zone 10a can generate an aerosol. It is understood that once the entire strip medium 20 has passed through the heating zone 10a, it is considered that the strip medium 20 has been used up.

[0266] The housing 10 can store and contain the strip medium 20, that is, the unused strip medium 20 is stored in the housing 10. During the use of the atomizing medium assembly 100, the unused strip medium 20 passes through the heating zone 10a in sequence and is heated and used. The used strip medium 20 is still stored in the housing 10.

[0267] The specific method by which the strip medium 20 generates an aerosol within the heating region 10a is not limited. For example, referring to Figures 24 to 27, the host 200 includes a heating component 220, and the strip medium 20 within the heating region 10a generates an aerosol under the influence of the heating component 220. The heating method of the heating component 220 includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating, and laser heating. Of course, atomization can also be achieved using methods such as ultrasound; no specific limitation is made here.

[0268] The aerosol generated within the heating zone 10a can flow out through the exhaust channel 111a for user use. The suction component 300 is connected to the housing 10 and communicates with the exhaust channel 111a, allowing the user to suction the aerosol generated within the heating zone 10a using the suction component 300.

[0269] The negative pressure sensor 260 can detect negative pressure signals. Thus, when the user is aspirating aerosol, the aerosol generating device can obtain the aspiration signal in a timely manner through the negative pressure sensor 260, thereby controlling the aerosol generating device to start and achieving the effect of immediate aspiration.

[0270] The two ends of the negative pressure airway 111b are connected to the outlet airway 111a and the negative pressure sensor 260, respectively. Specifically, the negative pressure airway 111b is directly connected to the outlet airway 111a, that is, the connection point between the negative pressure airway 111b and the outlet airway 111a is located on the side wall of the outlet airway 111a. During the process of the user aspirating the aerosol through the suction device 300, the outlet airway 111a is relatively close to the suction device 300, and the airflow of the negative pressure airway 111b can also enter the outlet airway 111a relatively easily. In this way, negative pressure can be generated more easily in the negative pressure airway 111b, which makes it easier for the negative pressure sensor 260 to obtain the suction signal.

[0271] Understandably, in this embodiment, when the user inhales the aerosol, a relatively stable negative pressure can be formed within the negative pressure airway 111b, thereby enabling the negative pressure sensor 260 to obtain the inhalation signal relatively stably. This reduces the sealing requirements of the housing 10 and facilitates its manufacturing. Furthermore, when the heating component 220 employs contact heating, such as resistance heating, the heating component 220 needs to extend into the heating area 10a and heat the strip medium 20. In other words, when the atomizing medium component 100 is used in this type of aerosol generating device, the housing 10 cannot be made into a sealed structure. By directly connecting the negative pressure airway 111b to the outlet airway 111a, the atomizing medium component 100 can meet the requirements of this type of aerosol generating device.

[0272] However, in this type of aerosol generating device, the negative pressure airway 111b of the atomizing medium component 100 is directly connected to the air outlet channel 111a. After the user stops inhaling the aerosol, a portion of aerosol will still remain in the air outlet channel 111a. This portion of aerosol may flow back into the negative pressure airway 111b and block the negative pressure airway 111b.

[0273] The aerosol generating device is a handheld device. It is understood that, as a handheld device, users generally hold it along its thickness direction during use. The atomizing medium component 100 is relatively large, meaning that the thickness direction of the atomizing medium component 100 is generally the same as the thickness direction of the aerosol generating device.

[0274] It should be noted that the dimensions of different components in the three directions are different in the same absolute coordinate system. Generally, the length, width and thickness of an object are determined by the dimensions of the object extending in the three directions, with length > width > thickness. Therefore, the thickness direction of different components may be different. Thus, the following description will specify which component's thickness direction it refers to.

[0275] Specifically, please refer to Figure 24. The width direction of the atomizing medium assembly 100 is shown as d5 in the figure, and the thickness direction of the aerosol generating device is shown as d9 in the figure.

[0276] Based on the above explanation, it can be understood that during the use of the aerosol generating device, the thickness direction of the atomizing medium component 100 is closer to the direction of gravity. In related technologies, the extension direction of the negative pressure airway is parallel to the thickness direction of the atomizing medium component. After the user stops inhaling the aerosol, the residual aerosol in the outlet channel is easily flowed back into the negative pressure airway under the action of gravity, causing blockage of the negative pressure airway. Consequently, the negative pressure sensor cannot accurately detect the negative pressure, and the aerosol generating device cannot accurately obtain the suction signal, resulting in relatively low reliability of the aerosol generating device.

[0277] It should be noted that the technical solutions provided in the above-mentioned related technologies are intended to provide background or context for the implementation of this application. The description herein does not imply that it is prior art simply because it is included in this section.

[0278] In the atomizing medium assembly of this application embodiment, on a plane perpendicular to the axis of the outlet channel 111a, the projection of the axis of the negative pressure airway 111b has a first angle with the thickness direction of the housing 10, and the first angle is not 0°. The extension direction of the negative pressure airway 111b deviates further from the direction of gravity, thereby increasing the difficulty of aerosol reflux into the negative pressure airway 111b, which helps to reduce the probability of aerosol entering the negative pressure airway 111b, thereby reducing the risk of blockage in the negative pressure airway 111b and improving the reliability of the connection between the negative pressure airway 111b and the negative pressure sensor 260. When the user inhales the aerosol, the negative pressure sensor 260 can detect the negative pressure signal relatively reliably, thereby facilitating the control of the aerosol generation device to start and stop, and improving the reliability of the aerosol generation device's inhalation function.

[0279] Furthermore, in contact-heated aerosol generating devices, since the heating component 220 of the aerosol generating device needs to extend into the heating area 10a, the housing 10 of the atomizing medium component 100 cannot be designed as a sealed structure. By connecting one end of the negative pressure airway 111b to the outlet airway 111a, a negative pressure is easily formed in the negative pressure airway 111b during the user's aerosol suction process. This facilitates the negative pressure sensor 260 to obtain the suction signal, thereby realizing the instant suction of the aerosol generating device. In other words, the atomizing medium component 100 of this application embodiment, while achieving the instant suction function of the aerosol generating device, also reduces the sealing requirements of the housing 10.

[0280] The thickness direction of the housing 10 includes two opposite directions, and the projection of the axis of the negative pressure airway 111b has two included angles with the thickness direction of the housing 10. It should be noted that when the two included angles are equal (i.e., both are 90°), the first included angle refers to either of the two included angles; when the two included angles are not equal, the first included angle refers to the smaller of the two included angles.

[0281] The first included angle is shown as α in Figure 29. It should be noted that the negative pressure airway 111b cannot actually be observed from the perspective shown in Figure 29; the outline of the negative pressure airway 111b is shown as a dashed line in the figure.

[0282] The atomizing medium assembly 100 is detachably disposed within the main unit 200. Specifically, referring to Figures 1, 24 to 27, the main unit 200 includes a main housing 210 and an outer cover 230. An installation area 210a is formed on the main housing 210, and a heating assembly 220 is disposed within the installation area 210a. The atomizing medium assembly 100 is detachably disposed within the installation area 210a, and the open side of the installation area 210a is closed by the outer cover 230. During suction, external airflow can enter the installation area 210a through the gap between the main housing 210 and the outer cover 230, thereby achieving air intake for the aerosol generating device. The main housing 210 and the outer cover 230 can be connected by, for example, magnetic connection, snap-fit, threaded connection, plug-in connection, or ultrasonic connection.

[0283] After the strip medium 20 is used up, the outer cover 230 can be removed from the main shell 210 to replace it with a new atomizing medium assembly 100. Of course, if the strip medium 20 and the shell 10 are detachable, the atomizing medium assembly 100 can be removed from the installation area 210a, the shell 10 can be opened, a new strip medium 20 can be replaced with the atomizing medium assembly 100, and then the atomizing medium assembly 100 can be installed in the installation area 210a.

[0284] The main unit 200 also includes a power supply assembly housed within the main housing 210. The heating assembly 220 is electrically connected to the power supply assembly and is used to heat the strip medium 20. The power supply assembly is permanently connected to the main housing 210 until it is depleted and can be discarded. Alternatively, the power supply assembly may be detachably connected to the main housing 210, meaning it can be removed and replaced, or it may be rechargeable (within or outside the aerosol generating device).

[0285] Please refer to Figures 1, 24 to 27. In one embodiment, the suction member 300 is flat, and the thickness direction of the suction member 300 is parallel to the thickness direction of the housing 10.

[0286] For example, the thickness direction of the suction member 300 is shown as d8 in Figure 24.

[0287] "Flat" means that the width dimension of the cross-section of the suction component 300 is greater than its thickness dimension. It should be noted that the cross-section of the suction component 300 is perpendicular to the axis of the exhaust channel 111a.

[0288] Understandably, the flat suction component 300 fits the user's lips better. By making the suction component 300 a flat structure, and with its thickness direction parallel to the thickness direction of the housing 10, the user can better guide the thickness direction of the housing 10 closer to the direction of gravity during suction, thus helping to deviate the negative pressure airway 111b further from the direction of gravity. Furthermore, since the suction component 300 guides the user's grip on the aerosol generator, the design requirements for the shape of the main unit 200 of the aerosol generator are reduced; the shape of the main unit 200 can be designed according to requirements.

[0289] Please refer to Figures 1, 24 and 25. In one embodiment, the host 200 is flat, and the thickness direction of the host 200 is parallel to the thickness direction of the housing 10.

[0290] For example, the thickness direction of the host 200 is shown as d9 in Figure 24.

[0291] Understandably, users typically hold the main unit 200 when using the aerosol generator. By designing the main unit 200 as a flat structure, and with its thickness direction parallel to that of the housing 10, the user can better guide the thickness direction of the housing 10 closer to the direction of gravity during suction, thus helping to further deviate the negative pressure airway 111b from the direction of gravity. Furthermore, because the main unit 200 guides the user's grip on the aerosol generator, the design requirements for the shape of the suction component 300 are reduced. The shape of the suction component 300 can be designed according to requirements, for example, it can be designed as a cylinder.

[0292] Please refer to Figure 24. In one specific embodiment, both the main unit 200 and the suction component 300 can be flat structures. The thickness direction of both the main unit 200 and the suction component 300 is parallel to the thickness direction of the housing 10. In this way, the suction component 300 and the main unit 200 can form a dual cooperation, further guiding the user to hold the aerosol generating device, which is conducive to controlling the user to hold the aerosol generating device according to the design concept.

[0293] Please refer to Figures 1 and 33. In one embodiment, the host 200 further includes a seal 250. The seal 250 is provided with a sealing channel 250a. The two ends of the seal 250 are respectively connected to the negative pressure sensor 260 and the housing 10, so that the negative pressure airway 111b is connected to the sensor through the sealing channel 250a.

[0294] The type of seal 250 is not limited. For example, it can be sealing silicone, etc.

[0295] By using the seal 250, the sealing performance between the negative pressure airway 111b and the negative pressure sensor 260 can be improved, thereby improving the reliability of the negative pressure sensor 260 in detecting negative pressure signals, which in turn improves the reliability of the aerosol generation device's pumping function.

[0296] Please refer to Figure 29. In one embodiment, the first included angle is not less than 45°. For example, it is 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc.

[0297] Understandably, the larger the angle of the first included angle, the closer the extension direction of the negative pressure airway 111b is to the horizontal plane when the user inhales the aerosol. This makes the aerosol less susceptible to the influence of gravity and allows it to flow back into the negative pressure airway 111b.

[0298] In this embodiment, the minimum angle of the first included angle is limited to not less than 45°. In this way, the angle of the first included angle will not be too small, thereby further reducing the probability of aerosol flowing back into the negative pressure airway 111b.

[0299] Please refer to Figure 29. In one embodiment, the first included angle is 90°. In this embodiment, during the user's aspiration of the aerosol, the negative pressure airway 111b extends essentially horizontally. That is, the two ends of the negative pressure airway 111b have virtually no height difference in the direction of gravity. Thus, the aerosol will not flow back into the negative pressure airway 111b, thereby improving the reliability of the aerosol generation device.

[0300] Please refer to Figures 29 to 31. In one embodiment, the negative pressure airway 111b extends from one end connected to the outlet airway 111a to the end connected to the negative pressure sensor 260 in a fifth direction. The outlet airway 111a extends from one end connected to the heating area 10a to the end connected to the outside in a sixth direction. There is a second included angle between the fifth direction and the sixth direction, and the second included angle is not greater than 90°.

[0301] For example, the fifth direction is the direction shown by d7 in Figure 31, the sixth direction is the direction shown by d6 in Figure 31, and the second included angle is the included angle shown by β in Figure 31.

[0302] It should be noted that the fifth and sixth directions are vector directions, meaning that each indicates only one direction.

[0303] It is understandable that when aerosols recirculate, they basically flow in the opposite direction to the sixth direction. By controlling the angle of the second included angle to no more than 90°, an acute angle is not formed between the fifth direction and the direction of aerosol recirculation. Thus, when the aerosols recirculate and pass through the connection between the negative pressure airway 111b and the outlet airway 111a, the sidewall of the negative pressure airway 111b has virtually no guiding effect on the aerosols, thereby reducing the probability of aerosols entering the interior of the negative pressure airway 111b through this connection.

[0304] Please refer to Figures 29 to 31. In one embodiment, the second included angle is not less than 30° and not greater than 60°. For example, it is 30°, 33°, 36°, 39°, 42°, 45°, 48°, 51°, 54°, 57°, 60°, etc.

[0305] Understandably, the smaller the second included angle, the closer the extension direction of the air outlet channel 111a is to the extension direction of the negative pressure airway 111b. During the user's aerosol suction process, since the heating area 10a is located at one end of the axial direction of the air outlet channel 111a, the gas in the heating area 10a is more likely to enter the air outlet channel 111a than the negative pressure airway 111b. This makes it difficult to form a negative pressure in the negative pressure airway 111b, thus making it difficult for the negative pressure sensor 260 to obtain a suction signal. When the second included angle is larger, it is understandable that during the user's holding of the aerosol generating device and suction of the aerosol, the thickness direction of the atomizing medium component 100 actually has a certain angle with the horizontal plane. That is to say, the height of the end of the negative pressure airway 111b near the negative pressure sensor 260 may be lower than the height of the end of the negative pressure airway 111b near the air outlet channel 111a, so there is still a certain probability that the aerosol will enter the negative pressure airway 111b.

[0306] By controlling the second included angle within this range, on the one hand, the second included angle is not less than 30°, and there is a sufficient included angle between the air outlet channel 111a and the negative pressure airway 111b. In this way, when the user inhales the aerosol, it is easy to generate negative pressure in the negative pressure airway 111b, so that the negative pressure sensor 260 can obtain the suction signal. On the other hand, the second included angle is not greater than 60°, and there is a sufficient included angle between the negative pressure airway 111b and the aerosol return direction. When the user holds the aerosol generating device and inhales the aerosol, it is beneficial to control the height of the end of the negative pressure airway 111b near the negative pressure sensor 260 to be higher than the height of the end near the air outlet channel 111a. In this way, the probability of aerosol returning to the negative pressure airway 111b can be further reduced.

[0307] Please refer to Figures 29 to 31. In one embodiment, the direction from one end of the air outlet channel 111a that is connected to the heating region 10a to the other end that is connected to the outside is the sixth direction. Along the sixth direction, the air outlet channel 111a includes a constriction section 111aa, a throat section 111ab, and an expansion section 111ac. The throat section 111ab connects the constriction section 111aa and the expansion section 111ac. One end of the negative pressure airway 111b is connected to the throat section 111ab.

[0308] Within the area defined by the contraction section 111aa, the expansion section 111ac, and the throat section 111ab, the cross-sectional area of ​​the exhaust passage 111a is the smallest at the throat section 111ab. In other words, the exhaust passage 111a is roughly formed as a Venturi structure that is thick at both ends and thin in the middle.

[0309] Specifically, when a user aspirates the aerosol, the airflow flows from the heating zone 10a through the outlet channel 111a. As it flows through the contraction section 111aa, the cross-sectional area of ​​the contraction section 111aa decreases, resulting in increased airflow velocity and decreased pressure. When the airflow flows through the throat section 111ab, a vacuum is generated on the side wall of the throat section 111ab. Since the negative pressure airway 111b connects to the throat section 111ab, that is, the negative pressure airway 111b is connected to the throat section 111ab... The passage is located on the side wall of the throat segment 111ab. Therefore, the air in the negative pressure airway 111b is drawn into the throat segment 111ab, thereby generating a significant negative pressure in the negative pressure airway 111b. The negative pressure sensor 260 can detect this negative pressure and control the aerosol generating device to be turned on based on the negative pressure. The aerosol generating matrix on the surface or inside of the strip medium 20 in the heating area 10a is heated to generate aerosol, and the aerosol flows toward the air outlet channel 111a.

[0310] In this embodiment, even though the heating zone 10a is close to atmospheric pressure, the Venturi effect can be used to generate sufficient negative pressure in the negative pressure air passage 111b, thereby enabling automatic control of the aerosol generating device to start or stop heating. In other words, the air outlet passage 111a of this structure reduces the sealing requirements of the housing 10, thus making it suitable for contact heating aerosol generating devices.

[0311] In addition, after the airflow passes through the throat section 111ab, it enters the expansion section 111ac, where the airflow velocity gradually decreases and the pressure gradually increases, reducing the turbulence intensity. Therefore, the pressure head loss is small, which is beneficial for carrying out aerosols.

[0312] Please refer to Figures 25 to 27 and Figures 29 to 31. In one embodiment, the end of the housing 10 is provided with a protruding post 111. At least a portion of the air outlet channel 111a and the negative pressure air channel 111b are provided on the protruding post 111. The protruding post 111 is used to connect with the suction component 300 of the aerosol generating device.

[0313] Specifically, please refer to Figures 28 to 32. The first outer shell 11 of the housing 10 includes a shell body 112 and a protrusion 111. A heating region 10a is defined between the shell body 112 and the second outer shell 12. A strip medium 20 is disposed in the region between the shell body 112 and the second outer shell 12.

[0314] The shape of the protrusion 111 is not limited. For example, it can be cylindrical, square, etc. For example, please refer to Figure 28. The protrusion 111 is cylindrical. The suction member 300 can be connected to the protrusion 111 at any angle in the circumferential direction, which facilitates user operation and improves the user experience.

[0315] The air outlet channel 111a is generally formed on the top side of the housing 10. The aerosol generated in the heating area 10a can be directly discharged through the protrusion 111. The protrusion 111 is closer to the user, and the aerosol can be transported to the outside from the air outlet channel 111a in a short time and used by the user.

[0316] The protrusion 111 facilitates the connection of the suction component 300 to the housing 10, thereby enabling the suction of aerosols.

[0317] The connection method between the suction component 300 and the protrusion 111 is not limited. For example, a detachable connection method such as plug-in or snap-fit ​​can be used.

[0318] As shown in Figures 25 to 28, 32, and 33, in some embodiments, the atomizing medium assembly 100 includes a sealing ring 60 sandwiched between the protrusion 111 and the suction member 300. The material of the sealing ring 60 is not limited; for example, it can be silicone. By providing the sealing ring 60 between the suction member 300 and the protrusion 111, the sealing performance between the suction member 300 and the protrusion 111 is improved, reducing the possibility of aerosol overflowing through the gap between them, and also reducing the possibility of external airflow entering the suction member 300 through the gap between them, thereby enabling the user to stably inhale aerosol through the suction member 300.

[0319] Please refer to Figures 24 to 32. In some embodiments, the protrusion 111 is provided with a mounting groove 111c, and the sealing ring 60 is disposed in the mounting groove 111c. The mounting groove 111c provides mounting space for the sealing ring 60, and the sealing ring 60 will not protrude too much from the side wall of the protrusion 111. Thus, the resistance encountered during the disassembly and assembly of the suction component 300 is smaller, making it easier for the user to operate.

[0320] Please refer to 10. In one embodiment, the housing 10 also has a storage space 10b and a receiving space 10c, which are separated. The atomizing medium assembly 100 also includes a storage disk 30 disposed in the storage space 10b and a receiving disk 40 disposed in the receiving space 10c. The storage disk 30 is used to wind the strip medium 20. The strip medium 20 can be unwound from the storage disk 30 and wound onto the receiving disk 40 after passing through the heating area 10a.

[0321] Specifically, please refer to Figure 32, where a storage space 10b and a receiving space 10c are defined between the shell body 112 and the second outer shell 12.

[0322] Storage space 10b and storage space 10c are separated. That is, by placing unused strip media 20 and used strip media 20 in two separate spaces, the unused strip media 20 and used strip media 20 are isolated from each other. This can, to some extent, reduce the possibility of cross-contamination of odors between the unused strip media 20 and used strip media 20. In addition, it can also prevent debris from used strip media 20 from sticking to unused strip media 20, thereby preventing the generation of burnt smells and other odors to some extent.

[0323] Please refer to Figures 24, 28, and 32. The main unit 200 includes a drive shaft 240, which is located in the installation area 210a. The housing 10 is provided with a drive connection hole 112a (specifically, the housing body 112 is provided with a drive connection hole 112a). The drive shaft 240 passes through the drive connection hole 112a and is driven to connect with the storage tray 40. The drive shaft 240 rotates to drive the storage tray 40 to rotate. Through the rotation of the storage tray 40, the used strip medium 20 can be wound onto the storage tray 40. At the same time, the storage tray 30 follows the storage tray 40 and is driven to unwind the strip medium 20 stored on the storage tray 30.

[0324] By setting up the storage disk 30, the storage disk 30 can be rotated, which facilitates the unwinding of the strip medium 20 from the storage disk 30 and reduces the friction between the strip medium 20 and the housing 10 during the unwinding process.

[0325] By setting up a storage tray 40, the storage tray 40 can be rotated, which helps to wind the strip medium 20 onto the storage tray 40 and reduce the friction between the strip medium 20 and the housing 10 during the winding process.

[0326] In related technologies, the aerosol generation matrix strip will deform, harden, and delaminate after being atomized by the heating component.
