[0027] In one embodiment, the projection of the heat insulation space onto a plane perpendicular to a first direction covers the projection of the heating area; wherein, the first direction is the arrangement direction of the heating area and the boss.

[0028] In one embodiment, the side of the heat insulation member facing the heating area is recessed to form the heat insulation space; and / or,

[0031] In one embodiment, the heat insulation element is made of ceramic or aerogel.

[0032] In one embodiment, one side of the receiving tank is open to form an opening, and the other sides are closed, with at least a portion of the heating assembly entering the receiving tank through the opening.

[0033] 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.

[0034] This application provides an aerosol generating apparatus, comprising:

[0035] The main unit, including the heating components;

[0036] The atomizing medium assembly described in any of the above embodiments is detachably mounted on the main unit, and at least a portion of the heating assembly extends into the receiving groove.

[0037] In one embodiment, the heating assembly includes at least one of a magnetic core module, an infrared module, and a microwave module.

[0038] This application provides an aerosol generating apparatus, comprising:

[0039] The main unit includes a negative pressure element and a heating assembly;

[0040] The atomizing medium assembly described in any of the above embodiments is detachably mounted on the main unit, and the negative pressure air passage is connected to the negative pressure element, and the heating assembly is used to heat the strip medium located in the heating area;

[0041] The suction component is connected to the housing assembly and communicates with the air outlet channel.

[0042] In one embodiment, the main unit further includes a fourth seal, the fourth seal having a sealing channel, and both ends of the fourth seal being connected to the negative pressure element and the housing assembly, respectively, so that the negative pressure air passage communicates with the negative pressure element through the sealing channel; and / or,

An air inlet groove is provided on the side wall of the installation area, and the air inlet groove is connected to the air inlet channel.

[0044] In this embodiment of the atomizing medium assembly, when used in an aerosol generating device, the internal cavity is only connected to the outside through an inlet channel and an outlet channel. That is, external airflow can only enter the internal cavity through the inlet channel and exit through the outlet channel, making the internal cavity a relatively sealed cavity. During aerosol extraction, this facilitates the generation of negative pressure within the internal cavity. The negative pressure element of the aerosol generating device can sense whether negative pressure is generated within the internal cavity through a negative pressure airway, and based on the negative pressure situation, the start and stop of the aerosol generating device can be controlled, thus enabling the aerosol generating device to perform instant extraction. Furthermore, the relatively sealed internal cavity reduces the probability of aerosol condensate overflowing to the outside of the housing assembly, thereby reducing the likelihood of aerosol condensate contaminating the main unit of the aerosol generating device. Since aerosol generating devices are generally handheld, reducing the probability of aerosol condensate overflow also reduces the probability of aerosol condensate contaminating the user, thereby improving the user experience.

[0045] In addition, the relatively sealed internal cavity facilitates the generation of negative pressure inside, and the air outlet channel does not need to be designed as a Venturi tube structure with a sudden narrowing of the diameter in the middle section. On the one hand, the structure of the air outlet channel can be simpler and easier to demold; on the other hand, after the diameter of the air outlet channel does not shrink, its flow area is larger, and the airflow is larger during the aerosol suction process, so that the user can suck up more aerosol with each breath.

[0072] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0073] Please refer to Figures 1 to 12. This application provides an atomizing medium assembly. The atomizing medium assembly 100 includes a housing assembly 110 and a strip medium 120. The housing assembly 110 has an internal cavity 110a, an air inlet channel 112n, an air outlet channel 111a, and a negative pressure airway 112m. The internal cavity 110a includes a heating region 10a. One end of the air inlet channel 112n and one end of the air outlet channel 111a are respectively connected to the heating region 10a. One end of the negative pressure airway 112m is connected to the air outlet channel 111a or the internal cavity 110a, and the other end is connected to the negative pressure element 240 of the aerosol generating device. The strip medium 120 is disposed in the internal cavity 110a and can move to the heating region 10a and be heated to generate aerosol. The internal cavity 110a is connected to the outside only through the air inlet channel 112n and the air outlet channel 111a.

[0074] Please refer to Figures 1 to 12. This application provides an aerosol generating device, which 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 element 240 and a heating component 220; the atomizing medium assembly 100 is detachably mounted on the main unit 200, and the negative pressure air passage 112m is connected to the negative pressure element 240; the heating component 220 is used to heat the strip medium 120 located in the heating area 10a; the suction component 300 is connected to the housing assembly 110 and communicates with the air outlet passage 111a.

[0075] The strip medium 120 is a flexible strip structure with a certain width and thickness, but its length can be extended and bent according to actual conditions.

[0076] The surface of the strip medium 120 is coated or internally permeated or embedded with an aerosol generating matrix for generating aerosols, including but not limited to pharmaceuticals or nicotine-containing materials.

[0077] For example, the strip medium 120 may include a base strip and an aerosol generating matrix that is alternately coated on the base strip.

[0078] 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.

[0079] 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.

[0080] The internal cavity 110a includes a heating region 10a, and the strip medium 120 is disposed within the internal cavity 110a. That is to say, the strip medium 120 is not entirely disposed within the heating region 10a; it may be partially located within the heating region 10a, and the other part may be disposed in other spaces of the internal cavity 110a other than the heating region 10a.

[0081] A portion of the strip medium 120 can move into the heating zone 10a and be heated to generate an aerosol. That is, the strip medium 120 can continuously pass through the heating zone 10a, and the aerosol-generating matrix on the portion of the strip medium 120 currently within the heating zone 10a can generate an aerosol. It is understood that once the entire strip medium 120 has passed through the heating zone 10a, it is considered that the strip medium 120 has been used up.

[0082] The housing assembly 110 can store and contain the strip medium 120. That is, unused strip medium 120 is stored in the housing assembly 110. During the use of the atomizing medium assembly 100, the unused strip medium 120 passes through the heating zone 10a in sequence and is heated and used. The used strip medium 120 is still stored in the housing assembly 110, thereby preventing the residue of the used strip medium from falling into the aerosol generating device and contaminating the aerosol generating device.

[0083] External airflow can enter the internal cavity 110a through the air intake channel 112n and flow into the heating area 10a, thereby carrying the aerosol generated in the heating area 10a out through the air outlet channel 111a for user use.

[0084] The shape of the air outlet channel 111a is not limited. Exemplarily, as shown in Figures 4, 5 and 7, in some embodiments, the air outlet channel 111a can be cylindrical. That is, the diameter of the air outlet channel 111a remains unchanged along the axial direction of the air outlet channel 111a.

[0085] The type of suction device 300 is not limited. For example, it can be a suction nozzle, which the user can hold in their mouth to facilitate the suction of aerosols.

[0086] The type of negative pressure element 240 is not limited. For example, it can be a negative pressure sensor or other component that can detect air pressure.

[0087] One end of the negative pressure airway 112m is connected to the air outlet channel 111a or the internal cavity 110a. That is to say, the negative pressure airway 112m can be directly connected to the air outlet channel 111a or indirectly connected to the air outlet channel 111a.

[0088] The direct connection between the negative pressure air duct 112m and the air outlet 111a means that the connection point between the negative pressure air duct 112m and the air outlet 111a is located on the side wall of the air outlet 111a; the indirect connection between the negative pressure air duct 112m and the air outlet 111a means that the negative pressure air duct 112m is connected to the air outlet 111a through other spaces, that is, the negative pressure air duct 112m is located in an area outside the air outlet path of the aerosol generating device.

[0089] It should be noted that the air outlet path of the aerosol generating device is the path through which the aerosol sequentially passes through the heating zone 10a, the air outlet channel 111a, and the suction component 300, and flows into the user's oral cavity.

[0090] The internal cavity 110a is connected to the outside only through the air inlet channel 112n and the air outlet channel 111a. That is, after the atomizing medium assembly 100 is used in the aerosol generating device, since one end of the negative pressure airway 112m is connected to the negative pressure element 240, the negative pressure airway 112m is not connected to the outside. During the process of the user drawing aerosol through the suction device 300, the air outlet channel 111a is connected to the user's mouth. External airflow can only enter the internal cavity 110a through the air inlet channel 112n, and after carrying the aerosol generated in the heating area 10a, it flows out through the air outlet channel 111a.

[0091] It is understandable that the internal cavity 110a is roughly a sealed cavity. During the process of the user drawing in aerosol, the external airflow can only enter the internal cavity 110a through the air inlet channel 112n. Therefore, negative pressure can be generated in the internal cavity 110a. The negative pressure element 240 is a device that can detect air pressure. That is, the negative pressure element 240 can sense whether negative pressure is generated in the internal cavity 110a through the negative pressure airway 112m. Based on the negative pressure generation status, the start and stop of the aerosol generation device can be controlled.

[0092] Understandably, under the same suction conditions, the magnitude of the negative pressure generated inside the internal cavity 110a can be adjusted by changing the diameter of the air intake channel 112n.

[0093] It should be noted that, since the internal cavity 110a is approximately a sealed cavity, the atomizing medium assembly 100 of this application embodiment is suitable for a non-contact heating aerosol generating device.

[0094] Non-contact heating refers to a heating method in which the heating component 220 does not directly contact the strip medium 120, thereby achieving heating of the strip medium 120. Specifically, in some embodiments, the heating component 220 may include at least one of a magnetic core module, an infrared module, and a microwave module. Thus, the heating component 220 can heat the strip medium 120 using methods such as magnetic core heating, infrared heating, or microwave heating. In other embodiments, atomization can also be achieved using methods such as ultrasound.

[0095] In related technologies, for aerosol generating devices to be suitable for contact heating, the heating component needs to contact the strip medium to heat it. In other words, the heating component needs to extend into the internal cavity. Therefore, the internal cavity of the atomizing medium component is generally designed to be open, making it difficult to generate negative pressure within the internal cavity and hindering the aerosol generating device from achieving its immediate extraction function.

[0096] 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.

[0097] In this embodiment of the application, the atomizing medium component, when used in an aerosol generating device, has its internal cavity 110a connected to the outside only through the inlet channel 112n and the outlet channel 111a. That is, external airflow can only enter the internal cavity 110a through the inlet channel 112n and exit through the outlet channel 111a, making the internal cavity 110a a relatively sealed cavity. During the user's aerosol extraction process, this facilitates the generation of negative pressure within the internal cavity 110a. The negative pressure element 240 of the aerosol generating device can sense whether negative pressure is generated within the internal cavity 110a through the negative pressure airway 112m. Based on the negative pressure situation, the start and stop of the aerosol generating device can be controlled, enabling the aerosol generating device to achieve the function of immediate extraction and shutdown. On the other hand, the relatively sealed internal cavity 110a also reduces the probability of aerosol condensate overflowing to the outside of the housing assembly 110, thereby reducing the probability of aerosol condensate contaminating the main unit 200 of the aerosol generating device; furthermore, since the aerosol generating device is generally handheld, reducing the probability of aerosol condensate overflow also reduces the probability of aerosol condensate contaminating the user, thereby improving the user experience.

[0098] In addition, the internal cavity 110a is relatively sealed, which facilitates the generation of negative pressure inside it. The air outlet channel 111a does not need to be designed as a Venturi tube structure with a sudden decrease in diameter in the middle section. On the one hand, the structure of the air outlet channel 111a can be simpler and easier to demold. On the other hand, after the diameter of the air outlet channel 111a does not shrink, its flow area is larger, and the airflow is larger during the aerosol suction process, so that the user can suck up more aerosol with each breath.

[0099] The atomizing medium assembly 100 is detachably mounted on the main unit 200. Thus, after the strip medium 120 within the atomizing medium assembly 100 is used up, the atomizing medium assembly 100 can be removed and replaced with a new one. Alternatively, if the atomizing medium assembly 100 itself can replace the strip medium 120, it can be first removed from the main unit 200, a new strip medium 120 replaced, and then the atomizing medium assembly 100 reinstalled on the main unit 200. In this way, the housing assembly 110 can be reused, thereby reducing the user's operating costs.

[0100] Please refer to Figures 3 to 9. In one embodiment, the housing assembly 110 includes a housing 10 having a storage space 10b, a receiving space 10c, and a heating area 10a. The housing assembly 110 also includes a storage disk 40 disposed in the storage space 10b and a receiving disk assembly 50 disposed in the receiving space 10c. The storage disk 40 is used to wind a strip medium 120. The strip medium 120 can be unwound from the storage disk 40 and wound onto the receiving disk assembly 50 after passing through the heating area 10a.

[0101] It is understood that in this embodiment, the internal cavity 110a is defined by the housing 10, the storage disk 40, and the receiving disk assembly 50. In addition to the heating area 10a, the internal cavity 110a also includes a portion of the storage space 10b and a portion of the receiving space 10c. That is, it includes the portion of the storage space 10b not occupied by the storage disk 40 and the portion of the receiving space 10c not occupied by the receiving disk assembly 50.

[0102] Furthermore, the air intake passage 112n, the air outlet passage 111a, and the negative pressure air passage 112m are provided on the housing 10.

[0103] Storage space 10b and storage space 10c can be separated. That is, by placing unused strip media 120 and used strip media 120 in two separate spaces, the unused strip media 120 and used strip media 120 can be isolated from each other. This can improve the situation where the unused strip media 120 and used strip media 120 mix odors to a certain extent. In addition, it can also prevent the debris generated by used strip media 120 from sticking to unused strip media 120, thereby also preventing the generation of burnt smells and other odors to a certain extent.

[0104] By setting up the storage disk 40, the storage disk 40 can be rotated, which facilitates the unwinding of the strip medium 120 from the storage disk 40 and reduces the friction between the strip medium 120 and the housing 10 during the unwinding process.

[0105] By setting up the storage tray assembly 50, the storage tray assembly 50 can be rotated, which is beneficial for winding the strip medium 120 onto the storage tray assembly 50, reducing the friction between the strip medium 120 and the housing 10 during the winding process.

[0106] 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.

[0107] 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 120, can reduce the generation of debris to a certain extent. Furthermore, by separating the storage space 10b from the storage space 10c, the possibility of debris entering the storage space 10b and adhering to the unused strip medium 120 is further reduced. In addition, by providing a storage tray assembly 50 within the storage space 10c for winding up the used strip medium 120, 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 120, a protective effect is provided for the unused strip medium 120, resulting in a better user experience.

[0108] Please refer to Figures 2, 7, 8, 10 and 11. In one embodiment, the housing 10 is further provided with a drive connection hole 112d that communicates with the storage space 10c. The drive connection hole 112d is used to pass through the drive shaft 260 of the aerosol generating device so that the drive shaft 260 can be driven to connect with the storage tray assembly 50. The housing assembly 110 also includes a first seal 20, which is sealed and clamped between the storage tray assembly 50 and the side wall of the storage space 10c located at the outer edge of the drive connection hole 112d.

[0109] Please refer to Figures 2, 6 to 8. The host 200 includes a drive shaft 260, which is located in the mounting area 210a. The drive shaft 260 passes through the drive connection hole 112d and is driven to connect with the storage tray assembly 50. The drive shaft 260 rotates to drive the storage tray assembly 50 to rotate. Through the rotation of the storage tray assembly 50, the used strip medium 120 can be wound onto the storage tray assembly 50. At the same time, the storage tray 40 follows the storage tray assembly 50 and is driven to unwind the strip medium 120 stored on the storage tray 40.

[0110] The drive connection hole 112d facilitates the drive connection between the storage tray assembly 50 and the drive shaft 260, thereby enabling automated control of the rotation of the storage tray assembly 50.

[0111] The material of the first seal 20 is not limited. For example, it can be silicone, etc. Silicone basically does not produce harmful substances, thus helping to ensure the user's health.

[0112] The first seal 20 has an annular structure, and the first seal 20 is distributed at the outer edge of the drive connection hole 112d along its circumference.

[0113] Because the storage space 10c is connected to the outside through the drive connection hole 112d, and the storage tray assembly 50 needs to rotate, a certain gap needs to be maintained between it and the side wall of the storage space 10c, so that the external airflow may enter the internal cavity 110a through the drive connection hole 112d and this gap.

[0114] In this embodiment, by providing a first sealing element 20, the first sealing element 20 can seal the gap between the storage tray assembly 50 and the side wall of the storage space 10c, reducing the possibility of external airflow entering the internal cavity 110a through the drive connection hole 112d and the gap between the storage tray assembly 50 and the side wall of the storage space 10c, thereby improving the sealing performance of the internal cavity 110a.

[0115] Furthermore, the first seal 20 can be made of a flexible material, which has minimal impact on the rotation of the storage tray assembly 50 and can also provide a certain damping force for the rotation of the storage tray assembly 50. That is, without affecting the rotation of the storage tray assembly 50, it can also make the strip medium 120 have a certain preload during rotation, improve the reliability of the strip medium 120 during movement, and prevent the strip medium 120 from being damaged during movement.

[0116] Please refer to Figures 2, 6 to 8. In one embodiment, the storage tray assembly 50 includes a storage tray 51 and a sealing cover 52. The storage tray 51 has an installation channel 51a coaxially arranged with the drive connection hole 112d. The installation channel 51a extends through both ends of the storage tray 51 along its axial direction. One end of the installation channel 51a is used to pass through the drive shaft 260. The sealing cover 52 is disposed in the installation channel 51a through the other end of the installation channel 51a and seals the other end of the installation channel 51a.

[0117] Specifically, in this embodiment, the storage tray 51 is used to wind the strip medium 120, the drive shaft 260 is driven to connect with the storage tray 51, and the first seal 20 is sandwiched between the storage tray 51 and the side wall of the storage space 10c located at the outer edge of the drive connection hole 112d.

[0118] By configuring the mounting channel 51a to extend through both ends of the storage tray 51 along its axial direction, the storage tray 51 can be ejected from the mold along both ends of the mounting channel 51a during injection molding. In other words, the storage tray 51 in this embodiment has a lower molding difficulty, thus facilitating production.

[0119] Since the mounting channel 51a is connected to the drive connection hole 112d, external airflow may enter the internal cavity 110a through the drive connection hole 112d and the mounting channel 51a.

[0120] By sealing one end of the mounting channel 51a axially with the sealing cap 52, the possibility of external airflow entering the internal cavity 110a through the mounting channel 51a is reduced.

[0121] The specific structure of the sealing cover 52 is not limited. For example, as shown in FIG8, the sealing cover 52 has a receiving groove, within which at least a portion of the drive shaft 260 is located. That is, along the radial direction of the mounting channel 51a, the sealing cover 52 and the drive shaft 260 have an overlapping area. When the axial dimension of the mounting channel 51a is fixed, both the sealing cover 52 and the drive shaft 260 can extend sufficiently into the mounting channel 51a. Therefore, on the one hand, the stability of the drive shaft 260 in driving the storage tray 51 to rotate is improved; on the other hand, the reliability of the sealing cover 52 installed within the mounting channel 51a is also improved, which is beneficial to improving the sealing reliability of the internal cavity 110a.

[0122] Furthermore, an installation gap can easily form between the sealing cover 52 and the side wall of the installation channel 51a.

[0123] The storage tray assembly 50 also includes a second seal 53, which is sandwiched between the outer wall of the sealing cover 52 and the side wall of the mounting channel 51a.

[0124] The material of the second seal 53 is not limited. For example, it can be silicone. Silicone basically does not produce harmful substances, thus helping to ensure the user's health.

[0125] By sealing the outer wall of the sealing cover 52 and the side wall of the mounting channel 51a with a second seal 53, the possibility of external airflow entering the internal cavity 110a through the mounting gap between the sealing cover 52 and the side wall of the mounting channel 51a is further reduced.

[0126] The specific structure of the housing 10 is not limited, and it can be used to contain the strip medium 120. For example, referring to Figures 6 to 11, the housing 10 includes a first outer shell 11 and a second outer shell 12, which are sealed together and define a storage space 10b, a receiving space 10c, and a heating area 10a.

[0127] The first outer shell 11, the second outer shell 12, the storage tray assembly 50, and the storage tray 40 define an internal cavity 110a.

[0128] Specifically, a drive connection hole 112d, an air outlet channel 111a, an air inlet channel 112n, and a negative pressure air channel 112m can be provided on the first outer shell 11.

[0129] In this embodiment, it is convenient to install components such as the strip medium 120, the storage tray assembly 50, and the storage tray 40 inside the housing 10.

[0130] The first outer shell 11 and the second outer shell 12 are sealed together, which reduces the possibility of external airflow entering the internal cavity 110a through the installation gap between the first outer shell 11 and the second outer shell 12.

[0131] The strip medium 120 can be disposed in the area between the first housing 11 and the second housing 12. The first housing 11 and the second housing 12 can be detachably connected, so that after the strip medium 120 is used up, a new strip medium 120 can be replaced, and the housing 10 can be reused, thereby reducing the user's operating costs.

[0132] It should be noted that the specific method of sealing the first outer shell 11 and the second outer shell 12 is not limited. For example, referring to FIG9, in one embodiment, the shell 10 further includes a third sealing member 13, which is sealed and sandwiched between the first outer shell 11 and the second outer shell 12.

[0133] The material of the third seal 13 is not limited. For example, it can be silicone. Silicone basically does not produce harmful substances, thus helping to ensure the user's health.

[0134] By providing a third seal 13 between the first housing 11 and the second housing 12, the sealing performance between them is improved. The internal cavity 110a has better sealing performance, which facilitates the aerosol generating device to achieve the function of instant extraction.

[0135] In addition, by using a third seal 13 to seal the installation gap between the first housing 11 and the second housing 12, it is possible to make the first housing 11 and the second housing 12 a detachable connection structure, thereby facilitating the replacement of the strip medium 120.

[0136] In other embodiments, an ultrasonic seal is used to form a sealing structure between the first housing 11 and the second housing 12.

[0137] Ultrasonic sealing is a sealing method that utilizes ultrasonic technology. Its basic principle is to convert electrical energy into a high-frequency, high-voltage signal, which is then converted into high-frequency mechanical vibration by a transducer system. This vibration is applied to the contact surfaces that need to be sealed, causing high-speed friction between the two surfaces, raising the temperature, and melting the material at its melting point. Simultaneously, the material cools and solidifies under pressure, completing the sealing process.

[0138] The ultrasonic sealing process results in a better sealing connection and higher sealing strength between the first outer shell 11 and the second outer shell 12.

[0139] Please refer to Figures 4 to 11. In one embodiment, the end of the housing assembly 110 is provided with a protruding post 111, and at least a portion of the air outlet channel 111a is provided on the protruding post 111. The protruding post 111 is used to connect with the suction member 300 of the aerosol generating device. The housing assembly 110 also includes a sealing ring 30, which is sealed and clamped between the suction member 300 and the protruding post 111.

[0140] In one specific embodiment, please refer to Figures 9 to 11. The housing assembly 110 includes a housing 10, which 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. A heating area 10a, a storage space 10b, and a receiving space 10c are defined between the shell body 112 and the second outer shell 12. A strip medium 120 is disposed in the area between the shell body 112 and the second outer shell 12. A negative pressure air passage 112m and an air inlet passage 112n are disposed on the shell body 112.

[0141] The shape of the protrusion 111 is not limited. For example, it can be cylindrical, square, etc. For example, please refer to Figures 9 to 11. 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.

[0142] 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.

[0143] The protrusion 111 facilitates the connection of the suction component 300 to the housing 10, thereby enabling the suction of aerosols.

[0144] 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.

[0145] The material of the sealing ring 30 is not limited. For example, it can be silicone, etc. Silicone basically does not produce harmful substances, thus helping to ensure the user's health.

[0146] By setting a sealing ring 30 between the suction component 300 and the protrusion 111, the sealing performance between the suction component 300 and the protrusion 111 is better, reducing the possibility of aerosol overflowing through the gap between the two, and also reducing the possibility of external airflow entering the suction component 300 through the gap between the two, so that the user can stably suck up aerosol through the suction component 300.

[0147] Furthermore, the enhanced sealing performance between the suction component 300 and the protrusion 111 facilitates the generation of negative pressure within the internal cavity 110a during the aerosol suction process via the suction component 300, thereby improving the reliability of the aerosol generation device's instant suction and stop function.

[0148] Please refer to Figures 3 to 5. In some embodiments, the protrusion 111 is provided with a mounting groove 111b, and the sealing ring 30 is disposed in the mounting groove 111b. The mounting groove 111b provides mounting space for the sealing ring 30, and the sealing ring 30 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.

[0149] Please refer to Figures 3 to 5. In one embodiment, the negative pressure airway 112m is connected to the air outlet channel 111a through the internal cavity 110a.

[0150] In other words, the negative pressure airway 112m is located outside the outlet path of the aerosol generating device. Since the internal cavity 110a is a roughly sealed cavity, negative pressure is easily generated inside the internal cavity 110a. Therefore, by placing the negative pressure airway 112m outside the outlet path, the negative pressure element 240 can reliably detect the generation of negative pressure when the user is drawing in aerosol, thereby controlling the aerosol generating device to start.

[0151] It should be noted that the air outlet path of the aerosol generating device is the path through which the aerosol sequentially passes through the heating zone 10a, the air outlet channel 111a, and the suction component 300, and flows into the user's oral cavity.

[0152] Even after the user stops suction, some aerosol will remain in the outlet channel 111a, which may flow back into the heating zone 10a. By placing the negative pressure airway 112m outside the outlet path of the aerosol generator, the possibility of aerosol flowing back into the negative pressure airway 112m can be reduced, thereby reducing the possibility of the negative pressure airway 112m being blocked by the aerosol condenser, and thus improving the reliability of the immediate suction and stop function of the aerosol generator.

[0153] In addition, aerosols are less likely to enter the negative pressure airway 112m, which also reduces the chance of the negative pressure element 240 being contaminated by aerosols.

[0154] As shown in Figures 4, 5, 10 and 11, in some embodiments, the negative pressure airway 112m extends along the thickness direction of the housing 10.

[0155] 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 according to the dimensions of its extension in the three directions, with length > width > thickness. For example, the thickness direction of the shell 10 is shown as d2 in Figures 10 and 11.

[0156] As shown in Figures 1, 2 and 12, when the main unit 200 includes the fourth seal 250, the negative pressure element 240 and the fourth seal 250 are generally also located on one side of the atomizing medium assembly 100 in the thickness direction. This facilitates the docking of the negative pressure airway 112m with the sealing channel 250a of the fourth seal 250.

[0157] In other embodiments, the negative pressure air passage 112m may also extend along the width direction of the housing 10, that is, in the same direction as the extension of the air intake passage 112n.

[0158] The location of the air intake passage 112n is not limited. For example, referring to Figures 4 and 5, in one embodiment, the air intake passage 112n is located on both sides of the housing assembly 110 in the width direction.

[0159] It should be noted that the dashed arrows in Figure 5 represent the flow of air inside the atomizing medium assembly 100.

[0160] The width direction of the housing assembly 110 is the direction shown by d1 in Figures 4, 10 to 12.

[0161] Please refer to Figures 1 to 5 and Figure 12. In one embodiment, the main unit 200 includes an outer cover 230 and a main shell 210 with an installation area 210a. The heating component 220 and the atomizing medium component 100 are both disposed in the installation area 210a. The outer cover 230 closes the open side of the installation area 210a, and external airflow can enter the installation area 210a through the gap between the main shell 210 and the outer cover 230. An air inlet groove 210b is provided on the side wall of the installation area 210a, and the air inlet groove 210b communicates with the air inlet channel 112n.

[0162] The atomizing medium assembly 100 is detachably disposed within the installation area 210a, and the open side of the installation area 210a is sealed by the outer cover 230. During the suction process, external airflow can enter through the gap between the main shell 210 and the outer cover 230, and then sequentially pass through the air inlet groove 210b and the air inlet channel 112n to reach the heating area 10a, thereby realizing the air intake of the aerosol generating device. The main shell 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.

[0163] By creating an air inlet groove 210b on the side wall of the installation area 210a, the dimensions of the installation area 210a can be designed to accommodate the installation of the atomizing medium assembly 100. This allows the atomizing medium assembly 100 to fit snugly against the side wall of the installation area 210a, except for the air inlet groove 210b. This provides a certain degree of restraint for the atomizing medium assembly 100 within the installation area 210a, improving its installation stability. Simultaneously, the air inlet groove 210b allows external airflow to flow smoothly into the air intake channel 112n, thus facilitating the intake of the aerosol generating device.

[0164] After the strip medium 120 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 120 and the shell assembly 110 are detachable, the atomizing medium assembly 100 can be removed from the installation area 210a, the shell assembly 110 can be opened, a new strip medium 120 can be replaced with the atomizing medium assembly 100, and then the atomizing medium assembly 100 can be installed in the installation area 210a.

[0165] 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 120. 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).

[0166] Please refer to Figures 3 to 5 and Figure 12. The air intake slot 210b can be opened on both sides of the installation area 210a along the width direction of the aerosol generating device, so as to correspond one-to-one with the air intake channel 112n.

[0167] It should be noted that the width direction of the aerosol generating device is the same as the width direction of the housing assembly 110.

[0168] Please refer to Figures 11 and 12. In one embodiment, the host 200 further includes a fourth seal 250. The fourth seal 250 is provided with a sealing channel 250a. The two ends of the fourth seal 250 are respectively connected to the negative pressure element 240 and the housing assembly 110, so that the negative pressure air passage 112m is connected to the negative pressure element 240 through the sealing channel 250a.

[0169] The material of the fourth seal 250 is not limited. For example, it can be silicone, etc. Silicone basically does not produce harmful substances, thus helping to ensure the user's health.

[0170] The fourth sealing element 250 can improve the sealing performance between the negative pressure airway 112m and the negative pressure element 240, thereby improving the reliability of the negative pressure element 240 in detecting the negative pressure in the internal cavity 110a, and thus improving the reliability of the aerosol generation device and its pumping function.

[0171] Please refer to Figures 6, 15 to 20. This application embodiment provides another atomizing medium assembly. The atomizing medium assembly 100 includes a housing 10, a strip medium 120, and a heat insulation member 60. The outer side wall of the housing 10 is recessed inward to form a receiving groove 112a on the outer side wall of the housing 10 and a boss 112b is formed inside the housing 10. The receiving groove 112a is used to receive at least a portion of the heating assembly 220 of the aerosol generating device. The housing 10 also has a heating region 10a located on one side of the boss 112b. A portion of the strip medium 120 can move into the heating region 10a and be heated to generate an aerosol. The heat insulation member 60 is disposed on the side of the boss 112b facing the heating region 10a and can separate the boss 112b and the strip medium 120 located in the heating region 10a.

[0172] Please refer to Figures 1 to 3, 6, and 13 to 20. In a second aspect, embodiments of this application provide another aerosol generating apparatus. The aerosol generating apparatus includes a main unit 200 and an atomizing medium assembly 100 according to any embodiment of this application. The main unit 200 includes a heating assembly 220; the atomizing medium assembly 100 is detachably disposed on the main unit 200, and at least a portion of the heating assembly 220 extends into a receiving groove 112a.

[0173] The specific structure of the housing 10 is not limited, and it can be used to accommodate the strip medium 120. For example, referring to Figures 6, 17 to 19, 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 region 10a. The strip medium 120 can be disposed in the region 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 120 is used, a new strip medium 120 can be replaced, and the housing 10 can be reused, thereby reducing the user's operating costs.

[0174] The strip medium 120 is a flexible strip structure with a certain width and thickness, but its length can be extended and bent according to actual conditions.

[0175] The surface of the strip medium 120 is coated or internally permeated or embedded with an aerosol generating matrix for generating aerosols, including but not limited to pharmaceuticals or nicotine-containing materials.

[0176] For example, the strip medium 120 may include a base strip and an aerosol generating matrix that is alternately coated on the base strip.

[0177] 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.

[0178] 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.

[0179] A portion of the strip medium 120 can move into the heating zone 10a and be heated to generate an aerosol. That is, the strip medium 120 can continuously pass through the heating zone 10a, and the aerosol-generating matrix on the portion of the strip medium 120 currently within the heating zone 10a can generate an aerosol. It is understood that once the entire strip medium 120 has passed through the heating zone 10a, it is considered that the strip medium 120 has been used up.

[0180] The housing 10 can store and contain the strip medium 120. That is, the unused strip medium 120 is stored in the housing 10. During the use of the atomizing medium assembly 100, the unused strip medium 120 passes through the heating zone 10a in sequence and is heated and used. The used strip medium 120 is still stored in the housing 10.

[0181] The specific manner in which the strip medium 120 generates an aerosol within the heating zone 10a is not limited. For example, referring to Figures 2, 3, 13, and 14, the host 200 includes a heating assembly 220, and the strip medium 120 within the heating zone 10a generates an aerosol under the influence of the heating assembly 220.

[0182] The housing 10 also has an exhaust channel 111a, one end of which is connected to the heating zone 10a and the other end is connected to the outside. The aerosol generated in the heating zone 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 zone 10a.

[0183] To facilitate the immediate aerosol generation device's aerosol extraction function, please refer to Figures 17 to 19. In some embodiments, the aerosol generation device includes a negative pressure element 240, which may be, for example, a negative pressure sensor. The housing 10 is provided with a negative pressure airway 112m (specifically, the first outer shell 11 may be provided with a negative pressure airway 112m). One end of the negative pressure airway 112m is connected to the interior of the housing 10, and the other end is connected to the negative pressure element 240. The negative pressure element 240 can detect negative pressure signals. During the aerosol extraction process, negative pressure is generated in the negative pressure airway 112m. The aerosol generation device can obtain the extraction signal in a timely manner through the negative pressure element 240, thereby controlling the aerosol generation device to start, thus achieving the immediate extraction effect.

[0184] Understandably, given the instant extraction function of the aerosol generator, it is particularly important that negative pressure be generated simultaneously within the 112m negative pressure airway during the aerosol extraction process.

[0185] To facilitate the synchronous generation of negative pressure within the 112m negative pressure duct, related technologies have proposed placing one end of the negative pressure duct on the side wall of the outlet channel. This means the negative pressure duct is positioned close to the outlet channel, which in turn is close to the suction component. Therefore, when the user draws in aerosol through the suction component, negative pressure is easily generated within the negative pressure duct. Understandably, this type of aerosol generator can generate negative pressure relatively easily within the negative pressure duct, and the sealing performance requirements for the housing are not as stringent. However, because the negative pressure duct is directly connected to the outlet channel, after the user stops drawing in aerosol, residual aerosol in the outlet channel can flow back, potentially entering and blocking the negative pressure duct. If the negative pressure duct is blocked, the negative pressure element cannot accurately receive the suction signal, thus affecting the reliability of the aerosol generator.

[0186] 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.

[0187] To address the aforementioned technical issues, the housing 10 is configured as a relatively sealed structure. Exemplarily, the housing 10 also includes an air inlet channel 112n (specifically, the first outer shell 11 may have an air inlet channel 112n). The interior of the housing 10 is connected to the outside only through the air inlet channel 112n, the air outlet channel 111a, and the negative pressure air passage 112m. External airflow enters the interior of the housing 10 through the air inlet channel 112n and flows to the heating zone 10a, thereby carrying the aerosol generated within the heating zone 10a out through the air outlet channel 111a. The negative pressure air passage 112m is indirectly connected to the air outlet channel 111a. For example, it is connected to the air outlet channel 111a through the heating zone 10a. This reduces the risk of aerosol backflow and entry into the negative pressure air passage 112m, thereby improving the reliability of the aerosol generation device's extraction function. Based on this structure of the atomizing medium component 100, in order to facilitate the generation of aerosol from the strip medium 120 in the heating region 10a, a receiving groove 112a is provided. Part of the structure of the heating component 220 extends into the receiving groove 112a and can get closer to the strip medium 120 in the heating region 10a, thereby facilitating the generation of aerosol from the strip medium 120 in the heating region 10a under the influence of the heating component 220. Understandably, this type of atomizing medium assembly 100 requires high sealing performance from the housing 10. In order to facilitate the cooperation between the heating assembly 220 and the strip medium 120 in the heating area 10a, the receiving groove 112a and the boss 112b are particularly important. The boss 112b is close to the heating area 10a. During the use of the aerosol generating device, when the high-temperature strip medium 120 in the heating area 10a comes into contact with the boss 112b, it may burn the boss 112b. More seriously, the side wall of the boss 112b may be burned through, causing the inside of the housing 10 to communicate with the outside through the receiving groove 112a. The airtightness of the housing 10 is compromised, which may result in the inability to generate negative pressure in the negative pressure air passage 112m, thereby affecting the reliability of the aerosol generating device.

[0188] The atomizing medium assembly of this application embodiment includes a heat insulation member 60. The heat insulation member 60 is disposed on the side of the boss 112b facing the heating area 10a and can separate the boss 112b from the strip medium 120 located in the heating area 10a. During the user's aerosol suction process, the high-temperature strip medium 120 in the heating area 10a is isolated from the side wall of the boss 112b by the heat insulation member 60. The heat insulation member 60 has a good heat insulation effect, thereby reducing the probability of the boss 112b being burned by high temperature, that is, reducing the probability of the housing 10 being burned by the high-temperature strip medium 120, thereby improving the reliability of the aerosol generating device. In addition, the atomizing medium assembly of this application embodiment makes it easy to set the housing 10 into a relatively sealed structure, which facilitates the aerosol generating device to achieve the immediate suction function and also helps to improve the reliability of the aerosol generating device.

[0189] It should be noted that the atomizing medium assembly of this application embodiment is applicable to the heating assembly 220 that uses non-contact heating.

[0190] Non-contact heating refers to a heating method in which the heating component 220 does not directly contact the strip medium 120, thereby achieving heating of the strip medium 120.

[0191] In some embodiments, the heating component 220 includes at least one of a magnetic core module, an infrared module, and a microwave module. Thus, the heating component 220 can heat the strip medium 120 by means of magnetic core heating, infrared heating, or microwave heating.

[0192] In other embodiments, atomization may also be performed using methods such as ultrasound.

[0193] The atomizing medium assembly 100 is detachably disposed within the main unit 200. Specifically, referring to Figures 1 to 3, 6, 13, and 14, 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 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 112n, 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.

[0194] After the strip medium 120 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 120 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 120 can be replaced with the atomizing medium assembly 100, and then the atomizing medium assembly 100 can be installed in the installation area 210a.

[0195] 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 120. 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).

[0196] The manner in which the housing 10 forms the air outlet channel 111a is not limited. For example, referring to Figures 13, 14, 15 to 19, 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 120 is disposed in the region between the shell body 112 and the second outer shell 12.

[0197] Specifically, in this embodiment, the negative pressure air passage 112m can be disposed on the shell body 112. That is, the negative pressure air passage 112m is indirectly connected to the air outlet passage 111a. The air inlet passage 112n can also be disposed on the shell body 112.

[0198] The shape of the protrusion 111 is not limited. For example, it can be cylindrical, square, etc. For example, please refer to Figures 17 to 19. 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.

[0199] 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.

[0200] The protrusion 111 facilitates the connection of the suction component 300 to the housing 10, thereby enabling the suction of aerosols.

[0201] 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.

[0202] As shown in Figures 14 and 17 to 19, in some embodiments, the atomizing medium assembly 100 includes a sealing ring 30, which is sandwiched between the protrusion 111 and the suction member 300. The material of the sealing ring 30 is not limited; for example, it can be silicone. By providing the sealing ring 30 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.

[0203] Furthermore, the enhanced sealing performance between the suction component 300 and the protrusion 111 facilitates the generation of negative pressure within the negative pressure airway 112m during the aerosol suction process via the suction component 300, thereby improving the reliability of the aerosol generation device's suction function.

[0204] Please refer to Figures 15 to 19. In some embodiments, the protrusion 111 is provided with a mounting groove 111b, and the sealing ring 30 is disposed in the mounting groove 111b. The mounting groove 111b provides mounting space for the sealing ring 30, and the sealing ring 30 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.

[0205] Please refer to Figures 6, 15 and 16. In one embodiment, the housing 10 further includes a third seal 13, which is sandwiched between the first housing 11 and the second housing 12.

[0206] The material of the third seal 13 is not limited. For example, it can be sealing silicone, etc.

[0207] By providing a third seal 13 between the first housing 11 and the second housing 12, the sealing performance between them is improved. The sealing performance inside the housing 10 is better, which facilitates the aerosol generating device to achieve the instant extraction function.

[0208] Please refer to Figures 1 and 19. In one embodiment, the host 200 further includes a fourth seal 250. The fourth seal 250 is provided with a sealing channel 250a. The two ends of the fourth seal 250 are respectively connected to the negative pressure element 240 and the housing 10, so that the negative pressure air passage 112m is connected to the sensor through the sealing channel 250a.

[0209] The type of the fourth seal 250 is not limited. For example, it can be sealing silicone, etc.

[0210] The fourth sealing element 250 can improve the sealing performance between the negative pressure airway 112m and the negative pressure element 240, thereby improving the reliability of the negative pressure element 240 in detecting negative pressure signals, which in turn improves the reliability of the aerosol generation device's pumping function.

[0211] The manner in which the heat insulation member 60 separates the boss 112b and the heating area 10a is not limited. Exemplarily, as shown in Figures 14, 16 and 17, in some embodiments, the heat insulation member 60 is provided with a heat insulation space 60a, which is located between the heating area 10a and the boss 112b, and the strip medium 120 is separated from the inner wall of the heat insulation space 60a.

[0212] The strip medium 120 is separated from the inner wall of the heat insulation space 60a. That is to say, a certain gap space is formed between the strip medium 120 and the boss 112b, and air insulation is formed through this gap space, thereby improving the heat insulation effect of the heat insulation component 60.

[0213] In other embodiments, the heat insulation member 60 may not have a heat insulation space 60a. That is, the heat insulation member 60 abuts against the boss 112b and the strip medium 120 located in the heating area 10a respectively. Since the heat insulation member 60 itself has a certain heat insulation effect, the heat insulation member 60 with this structure can also meet the heat insulation requirements.

[0214] Please refer to Figures 3, 6, and 13 to 16. In one embodiment, the projection of the heat insulation space 60a onto a plane perpendicular to the third direction covers the projection of the heating area 10a; wherein, the third direction is the arrangement direction of the heating area 10a and the boss 112b.

[0215] For example, the third direction is the direction shown as d3 in Figure 13.

[0216] In this embodiment, the strip medium 120 located in the heating area 10a will not be in direct contact with the heat insulation member 60. Thus, air insulation is formed between the high-temperature strip medium 120 and the heat insulation member 60, which helps to reduce the heat transferred from the high-temperature strip medium 120 to the heat insulation member 60. The temperature of the side of the heat insulation member 60 facing the heating area 10a is lower, and the temperature of the side facing the boss 112b is also lower, thereby further reducing the probability of the boss 112b being burned by high temperature.

[0217] The specific manner in which the heat insulation member 60 forms the heat insulation space 60a is not limited. Exemplarily, as shown in Figures 3, 6 and 13 to 14, in some embodiments, the side of the heat insulation member 60 facing the heating area 10a is recessed to form the heat insulation space 60a.

[0218] In this embodiment, the strip medium 120 within the heating region 10a will not completely adhere to the heat insulation member 60. That is, at least a portion of the high-temperature strip medium 120 can form air insulation with the heat insulation member 60, which helps to control the temperature of the side of the heat insulation member 60 facing the heating region 10a, thereby helping to reduce the heat transferred to the boss 112b through the heat insulation member 60.

[0219] It is understandable that, since the side of the heat insulation component 60 facing the heating area 10a forms a heat insulation space 60a, the strip medium 120 in the heating area 10a will not basically adhere to the heat insulation component 60. Thus, after the strip medium 120 generates aerosol on the side facing the heat insulation component 60, it is also convenient for this part of the aerosol to be released.

[0220] In other embodiments, the side of the heat insulation member 60 opposite to the heating area 10a is recessed to form a heat insulation space 60a.

[0221] In this embodiment, the heat insulation element 60 is not completely attached to the boss 112b. The strip medium 120 in the heating area 10a can be attached to the side of the heat insulation element 60 away from the boss 112b. A portion of the boss 112b and the heat insulation element 60 can form air insulation through the heat insulation space 60a, thus effectively improving the heat insulation effect of the heat insulation element 60.

[0222] It is understandable that the heat insulation element 60 facing the heating area 10a can be set as a plane to support the strip medium 120, making the strip medium 120 more stable during movement.

[0223] In some embodiments, a heat insulation space 60a is formed inside the heat insulation member 60. That is, both sides of the heat insulation member 60 along the third direction can be configured as planar structures, so that the two sides of the heat insulation member 60 along the third direction can respectively fit with the strip medium 120 and the boss 112b.

[0224] For example, the third direction is the direction shown as d3 in Figure 13.

[0225] Please refer to Figures 14 and 17. In one embodiment, the side of the heat insulation member 60 facing the heating area 10a is recessed to form a heat insulation space 60a, and the strip medium 120 abuts against the unrecessed area of ​​the heat insulation member 60.

[0226] The non-recessed area of ​​the heat insulation component 60 can provide good support for the strip medium 120, improving the stability of the strip medium 120 during movement. At the same time, through the heat insulation space 60a, air insulation is formed between the strip medium 120 in the heating area 10a and the heat insulation component 60, which is beneficial to improving the heat insulation effect of the heat insulation component 60.

[0227] The structure of the heat insulation space 60a is not limited. For example, as shown in FIG20, the heat insulation space 60a can penetrate the sidewalls on opposite sides of the heat insulation member 60, thus the structure of the heat insulation member 60 is relatively simple and easy to process.

[0228] The material of the heat insulation element 60 is not limited. Exemplarily, in some embodiments, the heat insulation element 60 is made of ceramic or aerogel.

[0229] There are no restrictions on the type of ceramic. For example, it can be alumina ceramics, silicon nitride ceramics, silicon carbide ceramics, etc.

[0230] Aerogels can be, for example, silicone, etc.

[0231] The thermal insulation component 60 must possess high-temperature resistance. In other words, the thermal insulation component 60 itself must not be damaged under high-temperature conditions. Ceramics can withstand temperatures above 1000℃, and aerogels can withstand temperatures up to 1400℃. Therefore, thermal insulation components 60 made of ceramics or aerogels have better reliability and a longer service life.

[0232] It should be noted that aerosols are generally used for users to inhale, while the area where the heat insulation component 60 is located is connected to the heating area 10a. The heat insulation component 60, made of ceramic or aerogel, will not decompose into harmful substances under high temperature conditions, thus benefiting the user's health.

[0233] The heat insulation component 60 is located inside the housing 10. During use, if debris is generated inside the atomizing medium assembly 100, the debris will shake inside the housing 100, which can easily generate noise and may affect the delivery reliability of the strip medium 120. The heat insulation component 60, which is made of ceramic, has high reliability and a more stable overall structure, thus helping to reduce the risk of debris generation in the heat insulation component 60.

[0234] Please refer to Figures 2, 13, 14, 18 and 19. In one embodiment, one side of the receiving groove 112a is open to form an opening 112c, and the other sides are closed. At least a portion of the heating assembly 220 enters the receiving groove 112a through the opening 112c.

[0235] By providing the receiving groove 112a, the heating component 220 can be brought closer to the heating area 10a, thereby enabling the strip medium 120 in the heating area 10a to generate aerosol.

[0236] The receiving groove 112a is isolated from the inside of the housing 10, which facilitates the sealing design of the housing 10, thereby making it easier to generate negative pressure in the negative pressure air passage 112m, and thus realize the immediate extraction function of the aerosol generating device.

[0237] Please refer to Figures 3, 6, 13, 15 and 17. 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 40 disposed in the storage space 10b and a receiving disk 51 disposed in the receiving space 10c. The storage disk 40 is used to wind the strip medium 120. The strip medium 120 can be unwound from the storage disk 40 and wound onto the receiving disk 51 after passing through the heating area 10a.

[0238] Specifically, referring to Figures 15 and 17, a storage space 10b and a receiving space 10c are defined between the shell body 112 and the second outer shell 12.

[0239] Storage space 10b and storage space 10c are separated. That is, by placing unused strip media 120 and used strip media 120 in two separate spaces, the unused strip media 120 and used strip media 120 are isolated from each other. This can, to some extent, reduce the possibility of cross-contamination of odors between the unused strip media 120 and used strip media 120. In addition, it can also prevent debris from used strip media 120 from sticking to unused strip media 120, thereby also preventing the generation of burnt smells to some extent.

[0240] Please refer to Figures 2, 18, and 19. The main unit 200 includes a drive shaft 260, which is located in the mounting area 210a. The housing 10 is provided with a drive connection hole 112d (specifically, the housing body 112 is provided with a drive connection hole 112d). The drive shaft 260 passes through the drive connection hole 112d and is driven to connect with the storage tray 51. The drive shaft 260 rotates to drive the storage tray 51 to rotate. Through the rotation of the storage tray 51, the used strip medium 120 can be wound onto the storage tray 51. At the same time, the storage tray 40 follows the storage tray 51 and is driven to unwind the strip medium 120 stored on the storage tray 40.

[0241] By setting up the storage disk 40, the storage disk 40 can be rotated, which facilitates the unwinding of the strip medium 120 from the storage disk 40 and reduces the friction between the strip medium 120 and the housing 10 during the unwinding process.

[0242] By setting up the storage tray 51, the storage tray 51 can be rotated, which is beneficial for winding the strip medium 120 onto the storage tray 51 and reducing the friction between the strip medium 120 and the housing 10 during the winding process.

[0243] 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.

[0244] 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 120, 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 120 can be reduced. In addition, by providing a storage tray 51 within the storage space 10c for winding up the used strip medium 120, 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 120, a protective effect can be provided for the unused strip medium 120, resulting in a better user experience.

[0245] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
