Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to an aerosol generation product and an aerosol generation system. Background Technology

[0002] An aerosol generator is a small device that uses heat-not-burning (HNB) technology to act on an aerosol-generating matrix and produce aerosols. In related technologies, aerosol generators use heating components to heat the aerosol-generating matrix in an aerosol-generating product to generate aerosols for users to inhale. However, after a certain number of inhalations, the active ingredients in the aerosol-generating matrix are consumed. If the aerosol-generating matrix continues to be heated, it may release harmful components. To avoid this, users need to frequently replace the aerosol-generating matrix, affecting the user experience. Summary of the Invention

[0003] The embodiments of this application provide an aerosol generating article and an aerosol generating system to solve at least one of the above-mentioned technical problems.

[0004] The aerosol generating article according to embodiments of this application includes a body and a transmission assembly. The body has a receiving cavity and an atomizing gas channel located in the receiving cavity. The transmission assembly includes a drive shaft and a driven shaft rotatably disposed in the receiving cavity. The opposite ends of the aerosol generating matrix are respectively wound around the outer periphery of the drive shaft and the driven shaft. The drive shaft rotates to drive the aerosol generating matrix wound on the driven shaft through the atomizing gas channel and onto the drive shaft. The central axes of the atomizing gas channel, the drive shaft, and the driven shaft are in the same direction.

[0005] In some embodiments, the atomizing air passage is located between the active shaft and the driven shaft, and the aerosol generating matrix is ​​located outside the atomizing air passage.

[0006] In some embodiments, in the winding direction of the aerosol generating matrix, the length of the aerosol generating matrix not wound around the drive shaft and the driven shaft is less than or equal to the distance between the central axis of the drive shaft and the central axis of the driven shaft.

[0007] In some embodiments, in the winding direction of the aerosol generating matrix, the aerosol generating matrix includes a plurality of sections to be heated, and the drive shaft rotates to drive the plurality of sections to be heated sequentially through the atomizing air passage. Along the central axis of the atomizing air passage, each section to be heated includes at least two sub-sections, and the at least two sub-sections are sequentially heated to generate aerosol.

[0008] In some embodiments, the main body is further provided with an air inlet, which communicates with the atomizing air channel. The main body includes a base and a cover. The base is provided with the air inlet and the atomizing air channel. The cover is provided with a nozzle that communicates with the atomizing air channel. The nozzle and the air inlet are located on opposite sides of the main body, and the cover and the base together form the receiving cavity.

[0009] In some embodiments, the body is provided with a light-transmitting area for allowing light to enter and exit the accommodating cavity so that the light irradiates the aerosol generating matrix.

[0010] In some embodiments, the light-transmitting area is a solid area that transmits light.

[0011] In some embodiments, the light-transmitting area is a light-transmitting hollow area.

[0012] In some embodiments, the aerosol generating matrix includes a support portion and a matrix portion disposed on the support portion, wherein the light energy absorption rate of the support portion is greater than 90%.

[0013] The aerosol generation system of this application includes the aerosol generation article and aerosol generation device described in any of the above embodiments. The aerosol generation device includes a housing and a heating component, with at least a portion of the aerosol generation article disposed in the housing. The heating component is disposed in the housing and is used to heat the aerosol generation matrix.

[0014] In some embodiments, the central axis of the drive shaft and the central axis of the driven shaft extend along the length of the aerosol generating device.

[0015] In the aerosol generating article and aerosol generating system of this application, the transmission component includes a drive shaft and a driven shaft rotatably disposed in the accommodating cavity. The opposite ends of the aerosol generating matrix are respectively wound around the outer periphery of the drive shaft and the driven shaft. The drive shaft rotates to drive the aerosol generating matrix wound on the driven shaft through the atomizing air passage and then wound onto the drive shaft. Thus, when the effective ingredients in the aerosol generating matrix are completely consumed, the drive shaft can rotate to drive the unused aerosol generating matrix on the driven shaft through the atomizing air passage. This not only prevents the aerosol generating matrix, after the effective ingredients have been consumed, from being continuously heated and releasing harmful components, but also eliminates the need for users to frequently replace the aerosol generating matrix, resulting in a better user experience.

[0034] An aerosol generator is a small device that uses heat-not-burning (HNB) technology to act on an aerosol-generating matrix and produce aerosols. In related technologies, aerosol generators use heating components to heat the aerosol-generating matrix in an aerosol-generating product to generate aerosols for the user to inhale. However, after a certain number of inhalations, the active ingredients in the aerosol-generating matrix are consumed. If the aerosol-generating matrix continues to be heated, it may release harmful components. To avoid this, users need to frequently replace the aerosol-generating matrix, affecting the user experience. For solutions to these problems, please refer to [link to relevant documentation]. Figure 1 This application provides an aerosol generating article 100 and an aerosol generating system 1000.

[0035] Please see Figures 1 to 3 The aerosol generation system 1000 of this application includes an aerosol generation article 100 and an aerosol generation device 900. The aerosol generation device 900 includes a housing 200 and a heating component 300. At least a portion of the aerosol generation article 100 is disposed in the housing 200. The heating component 300 is disposed in the housing 200 and is used to heat the aerosol generation matrix 50 of the aerosol generation article 100.

[0036] The housing 200 is a structure in the aerosol generating device 900 that houses and protects the heating component 300 and other devices. The housing 200 can be made of materials including, but not limited to, plastics, aluminum alloys, copper, iron, steel, and carbon fiber composites. In one example, the housing 200 can be made of plastic, making it lighter and facilitating the portability of the aerosol generating device 900. In another example, the housing 200 can be made of a high-temperature resistant material, preventing damage (such as deformation) caused by heat and ensuring the stability and reliability of the aerosol generating device 900. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0037] The heating component 300 is a structure in the aerosol generating apparatus 900 capable of generating heat energy or transferring heat energy to other parts. In some embodiments, the heating component 300 can directly convert other forms of energy such as electrical energy, chemical energy, and solar energy into heat energy, and conduct it to other parts that need to be heated via heat transfer. In other embodiments, the heating component 300 emits other forms of energy such as electromagnetic waves, lasers, infrared light, or thermal radiation that can directly act on the surface of the part to be heated, so as to raise the temperature of the area receiving the electromagnetic waves, lasers, infrared light, or thermal radiation. In some embodiments of this application, the heating component 300 can emit a laser to the aerosol generating matrix 50, and the laser irradiates and heats the aerosol generating matrix 50 to generate aerosols. By using laser heating of the aerosol generating matrix 50, the aerosol generating matrix 50 can quickly generate aerosols, reducing the time required for the aerosol generating matrix 50 to generate aerosols when the aerosol generating device 900 is being aspirated. This ensures the freshness of the aerosols each time the user aspirates and allows the aerosol generating device 900 to achieve the effect of aspirating and stopping immediately, improving the user's aspiration experience.

[0038] The aerosol generating matrix 50 is a structure in the aerosol generating article 100 that can generate aerosols upon heating. The aerosol generating matrix 50 is a flexible, elongated structure with a certain width and thickness that can be bent. The length of the aerosol generating matrix 50 can be designed according to the type of aerosol generating device 900 or specific usage requirements. In some embodiments of this application, the aerosol generating matrix 50 includes a support portion and a matrix portion disposed on the support portion. Specifically, the matrix portion can be disposed on the support portion by coating, embedding, or infiltration. For example, when the heating component 300 can emit a laser to heat the aerosol generating matrix 50, the support portion can be an aluminum foil with an infrared absorbing coating, and the matrix portion can be disposed on the support portion by coating. The matrix portion is a processed element capable of generating aerosols under heating, ultrasonic, or mechanical vibration. Aerosols can be visible or invisible and may include vapors (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor.

[0039] Furthermore, in some embodiments, the light energy absorption rate of the carrier portion is greater than 90%. It should be noted that in some embodiments, the light energy absorption rate of the carrier portion can be any one of 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, and 100%, or any value between any two values.

[0040] The light energy absorption rate of the carrier part is greater than 90%. Therefore, when the heating component 300 emits a laser to the aerosol generating matrix 50, the carrier part can absorb most of the light energy and convert it into heat energy to heat the matrix part. This reduces light energy loss and improves the heating efficiency of the heating component 300 on the aerosol generating matrix 50. Consequently, it reduces the time required for the aerosol generating matrix 50 to generate aerosols when the aerosol generating device 900 is being pumped. This is beneficial for the aerosol generating device 900 to achieve the effect of pumping and stopping immediately, and improves the user's pumping experience.

[0041] Please combine Figure 2 In some embodiments, the aerosol generating device 900 further includes a support and a heat sink 600. The support is disposed within the housing 200. The heat sink 600 is connected to the support and is used to mount the heating element 300 and to dissipate heat from the heating element 300. It should be noted that in some embodiments, the heat sink 600 may be made of a material that is resistant to high temperatures and has a high thermal conductivity, such as copper, aluminum, polyetheretherketone (PEEK), high-melting-point metals, high-temperature ceramics, etc., and is not limited thereto.

[0042] Specifically, in some embodiments, during the operation of the heating component 300, the heat sink 600 can absorb the heat generated by the heating component 300 and dissipate the absorbed heat to the surrounding structural components, such as the bracket and the housing 200, thereby preventing the heat generated by the heating component 300 from accumulating, ensuring that the temperature of the heating component 300 is controllable, preventing the heating component 300 from overheating and causing damage, thereby extending the service life of the heating component 300 and ensuring the normal operation of the aerosol generating device 900.

[0043] In some embodiments, the heat sink 600 and the bracket are an integral structure, meaning they can be molded into a single unit. This not only improves the stability of the connection between the heat sink 600 and the bracket but also facilitates heat transfer between them. In other embodiments, the heat sink 600 and the bracket are separate structures, meaning they are two distinct structures that can be joined together using either a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, bolted connections or snap-fit ​​connections; non-detachable connection methods include, but are not limited to, adhesive bonding or welding.

[0044] In some embodiments, the heating assembly 300 may include a circuit board and one or more laser chips. The circuit board is disposed on the heat sink 600, and the one or more laser chips are electrically connected to the circuit board and used to emit laser light onto the aerosol generating matrix 50 to raise the local temperature of the aerosol generating matrix 50 in contact with the laser, thereby generating an aerosol for the user to inhale. In one embodiment, the laser chip is non-removably fixed to the circuit board, wherein the fixing method may be welding, gluing, interference fit, etc., and is not limited thereto. In another embodiment, the laser chip is detachably mounted to the circuit board, wherein the mounting method may be snap-fit ​​connection, threaded connection, etc., and is not limited thereto.

[0045] Since the aerosol generation system 1000 in this embodiment includes an aerosol generation article 100, it is understood that the aerosol generation system 1000 has at least the same beneficial effects as the aerosol generation article 100. Therefore, for the beneficial effects of the aerosol generation system 1000, please refer to the beneficial effects of the aerosol generation article 100 described below.

[0046] Please see Figure 2 and Figure 3 The aerosol generating article 100 of this application includes a body 10 and a transmission assembly 30. The body 10 has a receiving cavity 101 and an atomizing air passage 103 located in the receiving cavity 101. The transmission assembly 30 includes a drive shaft 31 and a driven shaft 33 rotatably disposed in the receiving cavity 101. The opposite ends of the aerosol generating matrix 50 are respectively wound around the outer periphery of the drive shaft 31 and the driven shaft 33. The drive shaft 31 rotates to drive the aerosol generating matrix 50 wound on the driven shaft 33 through the atomizing air passage 103 and wound onto the drive shaft 31. The central axes of the atomizing air passage 103, the drive shaft 31, and the driven shaft 33 are in the same direction. That is, the central axis X of the atomizing air passage 103, the central axis A of the drive shaft 31, and the central axis B of the driven shaft 33 are in the same direction.

[0047] Specifically, the body 10 is the structure in the aerosol generating article 100 that accommodates and protects the transmission components 30 and other devices. The material of the body 10 includes, but is not limited to, plastics, aluminum alloys, copper, iron, steel, and carbon fiber composites. In one example, the body 10 can be made of plastic, making it lighter and facilitating the lightweight design of the aerosol generating article 100. In another example, the body 10 can be made of a high-temperature resistant material, preventing damage (such as deformation) caused by heat and ensuring the stability and reliability of the aerosol generating article 100. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0048] The transmission assembly 30 is a structure in the aerosol generating article 100 used to drive the aerosol generating matrix 50 to rotate. The cross-sectional dimensions of the drive shaft 31 and the driven shaft 33 may be the same or different. In some embodiments of this application, the receiving cavity 101 may include a spaced-apart winding cavity 1011 and a storage cavity 1013. The drive shaft 31 is rotatably disposed in the winding cavity 1011, and the driven shaft 33 is rotatably disposed in the storage cavity 1013. The central axis A of the drive shaft 31 and the central axis B of the driven shaft 33 are in the same direction. One end of the aerosol generating matrix 50 is wound around the outer periphery of the driven shaft 33, and the other end of the aerosol generating matrix 50 passes through the atomizing channel 103 and is connected to the outer periphery of the drive shaft 31. At least a portion of the aerosol generating matrix 50 not wound around the drive shaft 31 and the driven shaft 33 corresponds to the atomizing channel 103 and can be heated and atomized to generate an aerosol. When the active ingredient (the component that can be heated and atomized to generate an aerosol) in the aerosol generating matrix 50 corresponding to the atomizing air passage 103 is consumed, the drive shaft 31 can rotate about its central axis to drive the aerosol generating matrix 50 wound on the driven shaft 33 through the atomizing air passage 103 and onto the drive shaft 31. That is, when the drive shaft 31 rotates, the atomized aerosol generating matrix 50 can be wound onto the drive shaft 31, and the aerosol generating matrix 50 to be atomized on the driven shaft 33 can be moved to the position corresponding to the atomizing air passage 103.

[0049] It should be noted that in some embodiments, the atomizing airway 103 is located between the drive shaft 31 and the driven shaft 33. Therefore, compared to the atomizing airway 103 being located outside the drive shaft 31 and the driven shaft 33, the design space of the atomizing airway 103 is smaller, which allows for a higher aerosol concentration in the atomizing airway 103, ensuring the user's inhalation experience.

[0050] In some embodiments, the central axis A of the drive shaft 31 and the central axis B of the driven shaft 33 extend along the length of the aerosol generating device 900. This allows the drive shaft 31 and the driven shaft 33 to effectively utilize the space in the length direction of the aerosol generating device 900, which is beneficial for miniaturizing the aerosol generating system 1000.

[0051] Please combine Figure 2In some embodiments, the aerosol generating device 900 further includes a drive member 400 connected to the drive shaft 31 of the aerosol generating article 100, and the drive member 400 is used to drive the drive shaft 31 to rotate. Specifically, when the active ingredient in the aerosol generating matrix 50 corresponding to the atomizing channel 103 is consumed, the drive member 400 can drive the drive shaft 31 to rotate, so as to drive the aerosol generating matrix 50 wound on the driven shaft 33 through the atomizing channel 103 and wound onto the drive shaft 31, ensuring that the user can still inhale new aerosol during the next inhalation.

[0052] More specifically, in some embodiments, the angle of rotation of the drive shaft 31 driven by the drive member 400 can be the same each time, so that the step distance or linear velocity of the aerosol generation matrix 50 remains unchanged during each transmission process, thereby ensuring that the aerosol generation matrix on the aerosol generation matrix 50 can be effectively utilized, which is conducive to maximizing the utilization rate of the aerosol generation matrix 50.

[0053] Please combine Figure 5 In some embodiments, the aerosol generating article 100 further includes a seal 70, which is disposed between the drive shaft 31 and the body 10 to seal the gap between them. The seal 70 ensures normal rotation of the drive shaft 31 relative to the body 10 while sealing the gap between them, preventing impurities in the take-up cavity 1011 (such as debris from the carbonized matrix portion of the aerosol generating matrix 50) from entering the housing 200 and contaminating its interior. It should be noted that the seal 70 may be made of materials including, but not limited to, rubber, silicone, and polypropylene.

[0054] Furthermore, please combine Figure 1 In some embodiments, the aerosol generating apparatus 900 further includes a detection component 700 and a control component 800. The detection component 700 is disposed within the housing 200 and is used to detect whether the aerosol generating apparatus 900 is being aspirated and generate a detection signal. The control component 800 is disposed within the housing 200 and is electrically connected to the detection component 700, the heating component 300, and the drive unit 400 of the aerosol generating apparatus. The control component 800 is used to control the operation of the drive unit 400 and / or the heating component 300 based on the detection signal.

[0055] Specifically, in some embodiments, when the aerosol generating device 900 is being aspirated, the detection component 700 generates a detection signal and outputs it to the control component 800. The control component 800, based on the received detection signal, controls the drive component 400 to drive the drive shaft 31 to rotate and / or controls the heating component 300 to turn on (e.g., controls the heating component 300 to emit a laser), so that the heating component 300 heats the corresponding aerosol generating matrix 50. When the aerosol generating device 900 is not being aspirated, the detection component 700 outputs a signal to the control component 800, which, based on the received signal, controls the heating component 300 to stop heating, and repeats the above steps, thus achieving the effect of immediate aspiration and cessation. It should be noted that in some embodiments, the detection component 700 can output a detection signal to the control component 800 based on the aspiration force of the aerosol generating device 900, so that the control component 800 can control the increase or decrease of the heating power of the heating component 300, which is beneficial to improving the user's aspiration experience.

[0056] For example, when the effective components in the aerosol generating matrix 50 corresponding to the atomizing airway 103 have not been completely consumed and the aerosol generating device 900 is being aspirated, the detection component 700 can generate a detection signal and output the detection signal to the control component 800. The control component 800 controls the heating component 300 to turn on according to the received detection signal. When the effective components in the aerosol generating matrix 50 corresponding to the atomizing airway 103 have been completely consumed and the aerosol generating device 900 is being aspirated, the detection component 700 can generate a detection signal and output the detection signal to the control component 800. The control component 800 controls the drive component 400 to drive the drive shaft 31 to rotate and controls the heating component 300 to turn on according to the received detection signal.

[0057] In the aerosol generating article 100 of this application embodiment, the transmission assembly 30 includes a drive shaft 31 and a driven shaft 33 rotatably disposed in the accommodating cavity 101. The opposite ends of the aerosol generating matrix 50 are respectively wound around the outer periphery of the drive shaft 31 and the driven shaft 33. The drive shaft 31 rotates to drive the aerosol generating matrix 50 wound on the driven shaft 33 through the atomizing air passage 103 and wound onto the drive shaft 31. Thus, when the effective ingredients in the aerosol generating matrix 50 are consumed, the drive shaft 31 can rotate to drive the unused aerosol generating matrix 50 on the driven shaft 33 through the atomizing air passage 103. This not only prevents the aerosol generating matrix 50, after the effective ingredients have been consumed, from being continuously heated and releasing harmful components, but also allows the user to avoid frequently replacing the aerosol generating matrix 50, resulting in a better user experience.

[0058] The aerosol-generated product 100 will be further explained below with reference to the accompanying drawings.

[0059] Please see Figure 3 and Figure 4 It is understandable that if the aerosol generating matrix 50 is located inside the atomizing airway 103, the aerosol generating matrix 50 may obstruct or interfere with the suction when the user inhales the aerosol in the atomizing airway 103, which may result in the aerosol not being successfully extracted, affecting the user's suction experience. However, in some embodiments of this application, the aerosol generating matrix 50 is located outside the atomizing airway 103. For example, the aerosol generating matrix 50 is located on the side of the atomizing airway 103. This ensures that the aerosol generated by the heated aerosol generating matrix 50 can enter the atomizing airway 103; on the other hand, when the user inhales the aerosol in the atomizing airway 103, the aerosol generating matrix 50 will not obstruct or interfere with the suction, thus ensuring that the aerosol can be successfully extracted and guaranteeing the user's suction experience.

[0060] Since the matrix portion of the aerosol generating matrix 50 will carbonize after being heated and atomized to generate aerosol, if the aerosol generating matrix 50 comes into contact with other structures, the carbonized matrix portion is prone to falling off debris, which will cause contamination inside the accommodating cavity 101. Furthermore, the falling debris may affect the aerosol in the atomizing airway 103, affecting the user's inhalation experience.

[0061] Therefore, in some embodiments of this application, in the winding direction of the aerosol generating matrix 50, the length of the aerosol generating matrix 50 not wound around the drive shaft 31 and the driven shaft 33 is less than or equal to the distance between the central axis of the drive shaft 31 and the central axis of the driven shaft 33. That is, the length of the aerosol generating matrix 50 on its movement path outside the drive shaft 31 and the driven shaft 33 is less than or equal to the distance between the central axis of the drive shaft 31 and the central axis of the driven shaft 33. In this way, the movement path of the aerosol generating matrix 50 outside the drive shaft 31 and the driven shaft 33 is shorter, so that the aerosol generating matrix 50 can be immediately wound onto the drive shaft 31 after being heated and atomized to generate aerosol. This reduces the possibility of debris falling off the carbonized matrix portion, thereby preventing contamination inside the accommodating cavity 101 on the one hand, and preventing debris from falling off and affecting the aerosol on the other hand, ensuring the user's inhalation experience.

[0062] It should be noted that in some embodiments, the entire aerosol generating matrix 50 not wound around the drive shaft 31 and driven shaft 33 corresponds to the atomizing airway 103. In this case, when the user inhales, the entire aerosol generating matrix 50 not wound around the drive shaft 31 and driven shaft 33 can be simultaneously heated and atomized to generate an aerosol. In other embodiments, the portion of the aerosol generating matrix 50 not wound around the drive shaft 31 and driven shaft 33 corresponds to the atomizing airway 103. In this case, when the user inhales, the portion of the aerosol generating matrix 50 not wound around the drive shaft 31 and driven shaft 33 can be heated and atomized to generate an aerosol.

[0063] Furthermore, in some embodiments, the plane where the aerosol generating matrix 50, which is not wound around the drive shaft 31 and the driven shaft 33, is located intersects with the cross-sections of the drive shaft 31 and the driven shaft 33. Therefore, compared to the plane where the aerosol generating matrix 50, which is not wound around the drive shaft 31 and the driven shaft 33, is tangential to or spaced from the cross-sections of the drive shaft 31 and the driven shaft 33, the space between the drive shaft 31 and the driven shaft 33 can be utilized more effectively. For example, the heating assembly 300 and the atomizing air passage 103 can both be located within the space between the drive shaft 31 and the driven shaft 33, thereby making the structure of the aerosol generating article 100 more compact and facilitating miniaturization of the aerosol generating article 100.

[0064] Please see Figure 3 , Figure 4 and Figure 6 In some embodiments, the aerosol generating matrix 50 includes a plurality of heating parts 51 in the winding direction of the aerosol generating matrix 50, and the drive shaft 31 rotates to drive the plurality of heating parts 51 to pass through the atomizing air passage 103 in sequence.

[0065] Specifically, in some embodiments, during the rotation of the drive shaft 31, the aerosol generating matrix 50 on the driven shaft 33 can pass through the atomizing air passage 103 and be wound onto the drive shaft 31. During this process, multiple parts to be heated 51 can sequentially pass through the atomizing air passage 103 and be atomized to generate aerosol. For example, in the winding direction of the aerosol generating matrix 50, the aerosol generating matrix 50 includes three parts to be heated 51, which are sequentially a first part to be heated, a second part to be heated, and a third part to be heated. At this time, when the aerosol generating product 100 is in use, the first heating part corresponds to the atomizing air channel 103 to be atomized to generate aerosol. When the effective ingredient in the first heating part is consumed, the drive shaft 31 rotates to wind the first heating part onto the drive shaft 31. At the same time, the first heating part can drive the second heating part on the driven shaft 33 to move to the position corresponding to the atomizing air channel 103, so that the second heating part can be atomized to generate aerosol. Subsequently, when the effective ingredient in the second heating part is consumed, the drive shaft 31 rotates to wind the second heating part onto the drive shaft 31. At the same time, the second heating part can drive the third heating part on the driven shaft 33 to move to the position corresponding to the atomizing air channel 103, so that the third heating part can be atomized to generate aerosol.

[0066] It is understandable that the distance that the drive unit 400 drives the drive shaft 31 to rotate each time to move the aerosol generation matrix 50 is the same as the length of a heating part 51. This ensures that multiple heating parts 51 can pass through the atomizing air channel 103 in sequence and be atomized to generate aerosol.

[0067] It should be noted that, in some embodiments, the aerosol generating matrix 50 not wound around the drive shaft 31 and the driven shaft 33 includes at least one heated portion 51. In one example, the aerosol generating matrix 50 not wound around the drive shaft 31 and the driven shaft 33 includes one heated portion 51; in other words, the size of the aerosol generating matrix 50 not wound around the drive shaft 31 and the driven shaft 33 is the same as the size of one heated portion 51. In another example, the size of the aerosol generating matrix 50 not wound around the drive shaft 31 and the driven shaft 33 is larger than the size of one heated portion 51.

[0068] Please combine Figure 6In some embodiments, along the central axis X direction of the atomizing airway 103, each heated section 51 includes at least two sub-sections 53, and the at least two sub-sections 53 are sequentially heated to generate aerosol. Compared to each heated section 51 including only one sub-section 53, each heated section 51 can be drawn into more puffs. Given the same number of puffs that the aerosol generating matrix 50 can be drawn into, the aerosol generating matrix 50 in this application has a shorter design length. This reduces the stress generated by the winding deformation of the aerosol generating matrix 50 during the winding process, thereby reducing resistance during winding and facilitating stable delivery of the aerosol generating matrix 50, thus ensuring a stable taste across multiple puffs.

[0069] For example, in the winding direction of the aerosol generating matrix 50, the aerosol generating matrix 50 includes two heating portions 51, which are sequentially named a first heating portion and a second heating portion. Each heating portion 51 includes three sub-parts 53, which are sequentially named a first sub-part, a second sub-part, and a third sub-part along the central axis of the atomizing air passage 103. When the first part to be heated corresponds to the atomizing airway 103 and the aerosol generating device 900 is drawn in, the heating assembly 300 can sequentially heat the first sub-part, the second sub-part, and the third sub-part of the first part to be heated. Furthermore, when all the effective components in the sub-parts 53 of the first part to be heated are consumed, the drive member 400 can drive the drive shaft 31 to rotate so that the first part to be heated is wound onto the drive shaft 31. At the same time, the first part to be heated can drive the second part to be heated on the driven shaft 33 to move to the position corresponding to the atomizing airway 103. In this way, the heating assembly 300 can sequentially heat the first sub-part, the second sub-part, and the third sub-part of the second part to be heated.

[0070] Please see Figures 3 to 5 In some embodiments, the main body 10 is further provided with an air inlet 105, which is connected to the atomizing air channel 103. The air inlet 105 penetrates the main body 10 and is connected to the outside air, so that the outside air can enter the interior of the atomizing air channel 103 through the air inlet 105, so that the aerosol generating matrix 50 can generate aerosol when heated.

[0071] Furthermore, please combine Figure 1 and Figure 2In some embodiments, the detection component 700 may include a microphone for determining whether the aerosol generating device 900 is being aspirated based on air pressure. For example, when a user aspirates the aerosol generating device 900, the air pressure inside the aerosol generating device 900 gradually decreases to a negative pressure relative to the external air pressure. The microphone detects this pressure change and can determine that the aerosol generating device 900 is being aspirated. Therefore, the detection component 700 sends a detection signal to the control component 800, causing the control component 800 to control the drive component 400 and / or the heating component 300 to operate. When the user stops aspirating, the air pressure inside the aerosol generating device 900 gradually returns to a positive pressure. The microphone can determine that the aerosol generating device 900 is not being aspirated. Therefore, the detection component 700 sends a signal to the control component 800, causing the control component 800 to control the drive component 400 and / or the heating component 300 to stop operating.

[0072] In some embodiments, the main body 10 includes a base 11 and a cover 13. The base 11 is provided with an air inlet 105 and an atomizing air passage 103. The cover 13 is provided with a nozzle 15 communicating with the atomizing air passage 103. The nozzle 15 and the air inlet 105 are located on opposite sides of the main body 10, and the cover 13 and the base 11 together form a receiving cavity 101. The nozzle 15 allows the user to draw aerosol from the atomizing air passage 103. Furthermore, since the nozzle 15 and the air inlet 105 are located on opposite sides of the main body 10, the nozzle 15, the air inlet 105, and the atomizing air passage 103 can form a relatively straight airflow channel. This ensures that sufficient outside air enters the atomizing air passage 103 when the aerosol generating device 900 is drawn in, which is beneficial for aerosol generation. It also reduces suction resistance and improves the user's drawing experience.

[0073] Furthermore, in some embodiments, the mouthpiece 15 may include at least a filter section, which passes through the cover 13 and communicates with the atomizing airway 103. The user can inhale the aerosol generated in the atomizing airway 103 through the filter section. Moreover, as the aerosol passes through the filter section, the filter section can filter out impurities in the aerosol, preventing the user from inhaling impurities and improving the user's inhalation experience. It should be noted that the filter section includes, but is not limited to, porous materials, such as cotton or porous ceramics. Porous materials facilitate the flow of gas and aerosol and have good adsorption capacity, effectively adsorbing impurities in the airflow and preventing the user from inhaling impurities.

[0074] In some embodiments, the base 11 and the cover 13 may be an integral structure, that is, the base 11 and the cover 13 may be integrally molded to form a single structure, thereby improving the stability of the connection between the base 11 and the cover 13 and preventing the base 11 and the cover 13 from separating during use of the aerosol-generating product 100. In other embodiments, the base 11 and the cover 13 may be separate structures, that is, the base 11 and the cover 13 are two different structures, and the base 11 and the cover 13 may be combined by a detachable connection method or a non-detachable connection method. Among them, the detachable connection method includes, but is not limited to, bolt connection or snap connection; the non-detachable connection method includes, but is not limited to, adhesive or welding.

[0075] Please see Figure 3 and Figure 4 In some embodiments, the body 10 is provided with a light-transmitting area 17, which is used to allow light to enter and exit the accommodating cavity 101 so that the light can irradiate the aerosol generating matrix 50.

[0076] Specifically, please combine Figure 2 In some embodiments, the light-transmitting area 17 can correspond to the aerosol generating matrix 50 that is not wound onto the drive shaft 31 and the driven shaft 33. That is, the light-transmitting area 17 can correspond to the heating part 51 (the heating part 51 corresponding to the atomizing air channel 103). In this way, the laser and other light emitted by the heating component 300 can pass through the light-transmitting area 17 and directly heat the aerosol generating matrix 50, reducing the loss of the laser and other light in the propagation path.

[0077] In some embodiments, the light-transmitting area 17 is a solid area that transmits light. That is, the light-transmitting area 17 can be made of a light-transmitting material, which on the one hand allows light to shine onto the aerosol generating matrix 50, thereby ensuring the generation of aerosols; on the other hand, it can prevent external impurities such as water or dust from entering the receiving cavity 101 through the light-transmitting area 17 and causing contamination of the receiving cavity 101. The light-transmitting area 17 can be made of light-transmitting plastics such as PMMA (acrylic), PC (polycarbonate), PP (polypropylene), PET (polyethylene terephthalate), and PS (polystyrene).

[0078] In one embodiment, the body 10 is further provided with a non-transparent area to prevent light from illuminating other aerosol generating substrates 50, such as the aerosol generating substrate 50 wound on the driven shaft 33, thereby ensuring the amount of aerosol generated by the aerosol generating substrate 50 corresponding to the atomizing channel 103 after the drive shaft 31 rotates. The non-transparent area can be made of opaque materials, such as ABS plastic and PE (polyethylene). In another embodiment, the entire body 10 is made of a translucent material, which ensures normal light transmission and allows the user to easily observe the remaining amount of aerosol generating substrate 50 through the body 10.

[0079] It should be noted that, in some embodiments, when the light-transmitting area 17 is a light-transmitting solid area, the light-transmitting area 17 and the body 10 can be an integral structure, that is, the light-transmitting area 17 and the body 10 can be integrally molded to form a whole structure, thereby improving the stability of the connection between the light-transmitting area 17 and the body 10; or, the light-transmitting area 17 and the body 10 can be separate structures, that is, the light-transmitting area 17 and the body 10 are two different structures, and the light-transmitting area 17 and the body 10 can be combined by a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, bolt connections or snap-fit ​​connections; non-detachable connection methods include, but are not limited to, adhesive or welding.

[0080] In other embodiments, the light-transmitting area 17 is a light-transmitting hollow area. That is, the body 10 is provided with a through hole, which can be formed into the light-transmitting area 17. This can reduce the energy loss generated when light passes through the light-transmitting area 17, thereby ensuring atomization efficiency.
