Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to an atomizer and an aerosol generating device. Background Technology

[0002] An aerosol generator is a small device that uses heating technology to act on an aerosol-generating matrix and generate aerosols. In related technologies, the atomizer in an aerosol generator has an airflow path that allows outside air to flow to the bottom of the aerosol-generating matrix, enabling the matrix to generate aerosols when heated. Generally, the carbonization position of the aerosol-generating matrix changes continuously during the overheating process, while the air inlet position of the airflow path remains fixed. That is, the air inlet position of the airflow path does not change with the carbonization of the matrix. Therefore, the aerosols generated by the heated matrix cannot be effectively carried out, resulting in a small amount of aerosol and affecting the vaping experience. Utility Model Content

[0003] This application provides an atomizer and an aerosol generating device to solve at least one of the aforementioned technical problems.

[0004] This application provides an atomizer. The atomizer includes an atomizing base and an airway structure. The atomizing base has a receiving cavity for containing an aerosol generation matrix. The airway structure includes an air inlet and an air guide. The air inlet is connected to the atomizing base and has multiple air inlet channels, which are respectively connected from the bottom to different positions of the receiving cavity in the radial direction. The air guide has an air guide channel communicating with the outside air and includes a main body and an air guide portion. The air guide portion is movably disposed within the main body. During the movement of the air guide portion relative to the main body, the air guide channel and the multiple air inlet channels are sequentially connected to form an airflow path, which allows outside air to flow to different positions of the receiving cavity.

[0005] In some embodiments, the plurality of air intake channels include circular or annular channels that correspond to the cross-section of the accommodating cavity and are concentric.

[0006] In some embodiments, the radial dimensions of the plurality of air intake channels corresponding to the cross-section of the accommodating cavity are set to decrease sequentially from the inside to the outside.

[0007] In some embodiments, the air intake includes a substrate and a plurality of protrusions. The substrate is connected to the atomizing seat. The protrusions extend from the substrate toward the receiving cavity, and the plurality of protrusions are spaced apart and configured to participate in forming the air intake channel.

[0008] In some embodiments, the air guide is provided with a first channel, and the main body is provided with a plurality of second channels, each of which corresponds to a plurality of air intake channels. During the movement of the air guide relative to the main body, the first channel and the plurality of second channels are sequentially connected to form the air guide channel.

[0009] In some embodiments, the cross-sectional dimensions of the plurality of second channels gradually decrease in the direction of movement of the air guide.

[0010] In some embodiments, the cross-sectional dimensions of the plurality of second channels gradually increase in the direction of movement of the air guide.

[0011] In some embodiments, the cross-sectional dimensions of the second channel are the same as those of the corresponding intake channel.

[0012] In some embodiments, the air guide includes a first end and a second end opposite to each other, and a peripheral wall located between the first end and the second end, the peripheral wall having a through hole. The first channel includes a first sub-channel and a second sub-channel, the first sub-channel being recessed from the first end toward the second end, and the second sub-channel being recessed from the outside of the peripheral wall toward the inside of the air guide, the first sub-channel and the second sub-channel communicating through the through hole.

[0013] In some embodiments, the airway structure further includes a drive member connected to the air guide portion, the drive member being used to drive the air guide portion to move relative to the main body.

[0014] In some embodiments, the air intake and the air guide are an integral structure.

[0015] In some embodiments, the main body and the atomizing seat are separate structures.

[0016] In some embodiments, the air passage structure further includes a plurality of air guide tubes disposed between the air inlet and the air guide, and used to connect the corresponding air guide channel and the air inlet channel.

[0018] In the atomizer and aerosol generating device of this application, multiple air inlet channels are respectively connected to different positions in the radial direction of the accommodating cavity from the bottom. During the movement of the air guide relative to the main body, the air guide channel and the multiple air inlet channels are connected in sequence to form an airflow path. The airflow path is used to allow outside air to flow to different positions in the accommodating cavity. This enables the air inlet position of the airflow path to change according to the carbonization of the aerosol generating matrix, ensuring that the airflow path and the aerosol generating matrix are precisely matched. This ensures that the aerosol generated by the heating of the aerosol generating matrix is ​​effectively carried out, increasing the amount of aerosol that can be drawn out and improving the inhalation experience.

[0046] In related technologies, the atomizer in an aerosol generating device has an airflow passage for allowing outside air to flow to the bottom of the aerosol generating matrix, enabling the matrix to generate aerosols when heated. Generally, the carbonization position of the aerosol generating matrix changes continuously during superheating, while the air inlet position of the airflow passage remains fixed. That is, the air inlet position does not change with the carbonization of the matrix. Therefore, the aerosols generated by the heated matrix cannot be effectively carried out, resulting in a small amount of aerosol and affecting the vaping experience. To solve the above problem, please refer to [link to relevant documentation]. Figure 1 This application provides an atomizer 100 and an aerosol generating device 1000.

[0047] Please see Figure 1 The aerosol generating device 1000 provided in this application includes an electronic control component 300 and an atomizer 100, with the atomizer 100 electrically connected to the electronic control component 300.

[0048] It is understood that the aerosol generating device 1000 is a structure capable of generating aerosols by heating the aerosol generating matrix 3000. The aerosol generating matrix 3000 (e.g., Figure 2 (As shown) is a processed article that can generate aerosols upon heating. The aerosol generating matrix 3000 can be in liquid, fully solid, or semi-solid form. The aerosol 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 vapors. In some embodiments of this application, the aerosol generating matrix 3000 may be in solid form.

[0049] Furthermore, in some embodiments, the electronic control component 300 includes a controller and a power supply unit. The controller controls the operation of the atomizer 100, and the power supply unit is electrically connected to the controller and provides power to the controller and the atomizer 100. For example, when the aerosol generating device 1000 is being drawn in, the controller can control the power supply unit to output power to the atomizer 100. In this case, the atomizer 100 heats and atomizes the aerosol generating matrix 3000 to generate aerosol. When the aerosol generating device 1000 is not being drawn in, the controller can control the power supply unit to stop providing power to the atomizer 100. In this case, the atomizer 100 does not heat the aerosol generating matrix 3000. It should be noted that in some embodiments, the power supply unit can be a dry cell battery or a rechargeable battery; rechargeable batteries include, but are not limited to, lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries.

[0050] Since the aerosol generating device 1000 in this embodiment includes an atomizer 100, it is understood that the aerosol generating device 1000 has at least the same beneficial effects as the atomizer 100. Therefore, for the beneficial effects of the aerosol generating device 1000, please refer to the beneficial effects of the atomizer 100 described below.

[0051] Please see Figures 2 to 4(c) ,or Figures 5 to 7 The atomizer 100 provided in this application includes an atomizing base 10 and an airway structure 30. The atomizing base 10 is provided with a receiving cavity 11 for receiving an aerosol generating matrix 3000. The airway structure 30 includes an air inlet 31 and an air guide 33. The air inlet 31 is connected to the atomizing base 10 and is provided with multiple air inlet channels 311. The multiple air inlet channels 311 are respectively connected from the bottom to different positions of the receiving cavity 11 in the radial direction Y. The air guide 33 is provided with an air guide channel 331 communicating with the outside air, and includes a main body 333 and an air guide part 335. The air guide part 335 is movably disposed in the main body 333. During the movement of the air guide part 335 relative to the main body 333, the air guide channel 331 and the multiple air inlet channels 311 are sequentially connected to form an airflow passage 301. The airflow passage 301 is used to allow outside air to flow to different positions of the receiving cavity 11.

[0052] It is understood that the atomizer base 10 may be made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. In some embodiments, the atomizer base 10 may be made of plastic, which makes it lighter and facilitates the portability of the atomizer 100. In other embodiments, the atomizer base 10 may be made of high-temperature resistant materials, which reduces the possibility of damage (such as deformation) caused by heat, and improves the stability and reliability of the atomizer 100. High-temperature resistant materials include, but are not limited to, polyetheretherketone (PEEK), high-melting-point metals, and high-temperature ceramics.

[0053] In some embodiments of this application, the atomizing base 10 includes a base body 13 and a base 15, which are connected to form a receiving cavity 11. The base body 13 and the base 15 can be connected together by a detachable or non-detachable connection method. The detachable connection method includes, but is not limited to, bolt connection and snap-fit ​​connection; the non-detachable connection method includes, but is not limited to, bonding or welding.

[0054] The cross-sectional shape of the accommodating cavity 11 includes, but is not limited to, regular or irregular shapes such as square, circle, and triangle. In some embodiments of this application, the cross-section (including shape and size) of the accommodating cavity 11 is substantially the same as the cross-section (including shape and size) of the aerosol generating matrix 3000, which can improve the stability of the aerosol generating matrix 3000 in the accommodating cavity 11. For example, when the cross-sectional shape of the aerosol generating matrix 3000 is circular, the cross-sectional shape of the accommodating cavity 11 is also circular, and the cross-sectional dimensions of the accommodating cavity 11 are substantially the same as the cross-sectional dimensions of the aerosol generating matrix 3000.

[0055] The cross-sectional shape of the aerosol generating matrix 3000 includes, but is not limited to, regular or irregular shapes such as circles, ellipses, triangles, and squares. For ease of understanding, the following embodiments use a circle as an example to illustrate the cross-sectional shape of the aerosol generating matrix 3000.

[0056] For example, the aerosol generating matrix 3000 may include a multi-layer matrix section. Multiple air inlet channels 311 are located at different positions in the radial direction Y of the bottom corresponding to the receiving cavity 11; that is, each of the multiple air inlet channels 311 corresponds to a multi-layer matrix section. During the movement of the air guide section 335 relative to the main body 333, the air guide channel 331 and the multiple air inlet channels 311 are sequentially connected to form an airflow passage 301, which allows outside air to flow to different matrix sections.

[0057] Specifically, when the cross-sectional shape of the aerosol generating matrix 3000 includes a circle, the aerosol generating matrix 3000 can be cylindrical. In this case, all multi-layer matrix sections are cylindrical structures, and the outer contour of the cross-section of each multi-layer matrix section is circular. The multi-layer matrix sections are sequentially nested to form the aerosol generating matrix 3000. It can be understood that, in the direction from the outer peripheral wall of the aerosol generating matrix 3000 to its center—that is, from the outermost matrix section to the innermost matrix section—the cross-sectional dimensions of the multi-layer matrix sections gradually decrease; or, in the direction from the outermost matrix section to the innermost matrix section, the cross-sectional dimensions of the multi-layer matrix sections are all the same. It should be noted that the direction from the outer peripheral wall of the aerosol generating matrix 3000 to its center can be parallel to the radial direction Y.

[0058] In some embodiments of this application, the aerosol generating apparatus 1000 further includes a heating component 500, which heats the aerosol generating matrix 3000 to generate aerosols. The heating component 500 is a structure in the aerosol generating apparatus 1000 capable of generating heat energy or transferring heat energy to other parts. For example, the heating component 500 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. As another example, the heating component 500 emits other forms of energy, such as electromagnetic waves, laser light, infrared light, or thermal radiation, that can directly act on the surface of the part to be heated, thereby raising the temperature of the area receiving the electromagnetic waves, laser light, infrared light, or thermal radiation.

[0059] In some embodiments of this application, the heating component 500 can be a peripheral heating method. For example, the heating component 500 includes a heating element disposed around the outer side of the aerosol generating matrix 3000. The heating element generates heat to heat the aerosol generating matrix 3000. At this time, in the direction from the outer peripheral wall of the aerosol generating matrix 3000 to its center, the aerosol generating matrix 3000 carbonizes layer by layer and generates aerosols.

[0060] In some other embodiments of this application, the heating component 500 can be a central heating method. For example, the heating component 500 includes a heating element and a coil. The heating element extends into the center of the aerosol generating matrix 3000, and the coil is arranged around the outside of the aerosol generating matrix 3000. When the coil is energized, it generates a magnetic field. This magnetic field acts on the heating element, and using the eddy current effect, an induced rotating current (i.e., eddy current) proportional to the magnetic field strength is formed in the heating element. Thus, under the action of the eddy current, the heating element generates heat to heat the aerosol generating matrix 3000. At this time, in the direction from the center of the aerosol generating matrix 3000 to the outer peripheral wall of the aerosol generating matrix 3000, the aerosol generating matrix 3000 carbonizes layer by layer and generates aerosol.

[0061] The air passage structure 30 is a structure in the atomizer 100 used to allow outside air to flow to the aerosol generating matrix 3000. In some embodiments of this application, multiple air inlet channels 311 are respectively connected to the bottom of the corresponding receiving cavity 11 at different positions in the radial direction Y. Furthermore, during the movement of the air guide section 335 relative to the main body 333, the air guide channel 331 can sequentially connect with the multiple air inlet channels 311 to jointly form an airflow passage 301. That is, during the movement of the air guide section 335 relative to the main body 333, the air guide channel 331 can switch between the multiple air inlet channels 311 and connect with any one of the multiple air inlet channels 311 to jointly form an airflow passage 301, thereby allowing outside air to flow to different positions in the receiving cavity 11, that is, allowing outside air to flow to the corresponding matrix section.

[0062] For example, when the matrix includes three parts, the air intake channel 311 includes three parts. In this case, during the movement of the air guide 335 relative to the main body 333, the air guide channel 331 can be connected to the three air intake channels 311 in sequence to form an airflow passage 301. In other words, the air guide channel 331 can form three airflow passages 301 together with the three air intake channels 311. The three airflow passages 301 correspond one-to-one with the three matrix layers.

[0063] In some embodiments, the air intake 31 and the atomizing base 10 can be detachably connected, wherein the detachable connection includes, but is not limited to, snap-fit ​​connection and bolt connection. In other embodiments, the air intake 31 and the atomizing base 10 can be non-detachably connected, wherein the non-detachable connection includes, but is not limited to, interference fit, bonding or welding.

[0064] If the airflow passage 301 is only used to allow outside air to flow to the bottom of the entire aerosol generation matrix 3000, the fully carbonized aerosol cannot be effectively carried out during the suction process, resulting in a smaller amount of aerosol that can be suctioned. For example, the amount of aerosol suctioned in the first 3 puffs is small, which affects the suction taste. In the atomizer 100 of this application embodiment, during the movement of the air guide 335 relative to the main body 333, the air guide channel 331 and multiple air inlet channels 311 are sequentially connected to form an airflow passage 301. The airflow passage 301 is used to allow outside air to flow to different positions of the receiving cavity 11. That is, the air guide channel 331 can form multiple airflow passages 301 together with multiple air inlet channels 311, and the multiple airflow passages 301 correspond to different positions (i.e., multi-layer matrix parts) of the aerosol generating matrix 3000. This allows the air inlet position of the airflow passage 301 to change according to the carbonization of the aerosol generating matrix 3000, ensuring that the airflow passage 301 and the aerosol generating matrix 3000 are precisely matched. This ensures that the aerosol generated by the aerosol generating matrix 3000 when heated is effectively carried out, increasing the amount of aerosol that can be inhaled and improving the inhalation experience.

[0065] The atomizer 100 will be further described below with reference to the accompanying drawings.

[0066] Please see Figure 3 Figures 4(a) and 4(c), or Figure 6 and Figure 7 In some embodiments, the plurality of air intake channels 311 include circular or annular channels that correspond to the cross-section of the receiving cavity 11 and are concentric.

[0067] Specifically, the circular channel is the channel located in the middle of the air inlet 31 in Figure 4(a), and the annular channel is the multiple channels surrounding the circular channel in Figure 4(a). The circular and annular channels are respectively connected from the bottom to different positions of the accommodating cavity 11 in the radial direction Y, thereby allowing outside air to flow to different positions of the accommodating cavity 11. This ensures precise matching between the airflow passage 301 and the aerosol generating matrix 3000, effectively carrying out the aerosol generated by the heated aerosol generating matrix 3000, increasing the amount of aerosol that can be drawn out, and improving the suction experience.

[0068] It is understood that in other embodiments, the cross-sectional shape of the air intake channel 311 may also include other regular or irregular shapes besides circles and annular shapes. For example, referring to FIG4(b), multiple air intake channels 311 may include strip-shaped channels corresponding to the cross-section of the receiving cavity 11. The areas of the multiple strip-shaped channels corresponding to the cross-section of the receiving cavity 11 may be the same or different.

[0069] In some embodiments, the radial dimensions of the cross-sections of the multiple air intake channels 311 corresponding to the accommodating cavity 11 are all the same; or, the radial dimensions of the cross-sections of the multiple air intake channels 311 corresponding to the accommodating cavity 11 are set to increase sequentially from the inside to the outside. That is, in the direction from the center of the air intake member 31 to the outer side of the air intake member 31, the area of ​​the cross-sections of the multiple air intake channels 311 corresponding to the accommodating cavity 11 gradually increases. As a result, during the initial suction process, that is, during the first few suctions, more outside air can flow to the outer ring of the aerosol generating matrix 3000, thereby increasing the amount of aerosol generated and preventing the amount of aerosol sucked in the first few suctions from being too small, thus improving the suction taste.

[0070] In other embodiments, the radial dimensions of the cross-sections of the multiple air intake channels 311 corresponding to the accommodating cavity 11 are set to decrease sequentially from the inside to the outside. This ensures that the cross-sectional areas of the multiple air intake channels 311 corresponding to the accommodating cavity 11 are the same, thereby making the amount of aerosol generated during the suction process more consistent, and thus improving the consistency of the suction taste.

[0071] For example, when multiple air intake channels 311 include concentric circular or annular channels corresponding to the cross-section of the accommodating cavity 11, in the direction from the center of the air intake 31 to the outside of the air intake 31, the circular channel has the largest radial dimension corresponding to the cross-section of the accommodating cavity 11, and the outermost annular channel has the smallest radial dimension corresponding to the cross-section of the accommodating cavity 11.

[0072] Please see Figure 3 and Figure 4(c), or Figure 6 and Figure 7 In some embodiments, the air intake 31 includes a base plate 313 and a plurality of protrusions 315. The base plate 313 is connected to the atomizing seat 10. The protrusions 315 extend from the base plate 313 toward the receiving cavity 11, and the plurality of protrusions 315 are spaced apart and configured to participate in forming the air intake channel 311.

[0073] Specifically, in some embodiments, the cross-sectional shape of the protrusions 315 is annular; the air inlet channel 311 may include: the gap between the protrusions 315 (the protrusions 315 corresponding to the outer peripheral wall of the aerosol generating matrix 3000) and the inner wall of the accommodating cavity 11, the gap between two adjacent protrusions 315, and the inner cavity of the protrusions 315 (the protrusions 315 corresponding to the center of the aerosol generating matrix 3000). The cross-sectional shape and size of the air inlet channel 311 are approximately the same as the cross-sectional shape and size of the corresponding matrix layer, and when the aerosol generating matrix 3000 is accommodated in the accommodating cavity 11, the projection of the air inlet channel 311 onto the substrate 313 coincides with the projection of the corresponding matrix portion onto the substrate 313.

[0074] In some embodiments, the substrate 313 and the protrusion 315 are an integral structure, that is, the substrate 313 and the protrusion 315 are a single structure manufactured using an integral molding process. This improves the bonding strength between the substrate 313 and the protrusion 315, prevents the substrate 313 and the protrusion 315 from separating during use, and improves the stability and reliability of the atomizer 100. In other embodiments, the substrate 313 and the protrusion 315 are separate structures, that is, the substrate 313 and the protrusion 315 are two different structures. The substrate 313 and the protrusion 315 can be joined together using a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​connections; non-detachable connection methods include, but are not limited to, adhesive connections.

[0075] In some embodiments, the air guide 335 is provided with a first channel 3351, and the main body 333 is provided with a plurality of second channels 3331. The plurality of second channels 3331 correspond to a plurality of air intake channels 311 respectively. During the movement of the air guide 335 relative to the main body 333, the first channel 3351 and the plurality of second channels 3331 are connected in sequence to form the air guide channel 331.

[0076] Specifically, in some embodiments, the second channel 3331 corresponds one-to-one with the air intake channel 311. During the movement of the air guide 335 relative to the main body 333, the first channel 3351 can be sequentially connected with multiple second channels 3331 to jointly form the air guide channel 331. That is, the first channel 3351 can switch between multiple second channels 3331 and connect with any one of the multiple second channels 3331 to jointly form the air guide channel 331, so that the outside air flows through the air guide channel 331 to different air intake channels 311, thereby achieving precise matching between the airflow passage 301 and the aerosol generation matrix 3000.

[0077] For example, when the matrix includes three parts, the air intake channel 311 includes three parts, and the second channel 3331 also includes three parts. In this case, during the movement of the air guide 335 relative to the main body 333, the first channel 3351 can be connected to the three second channels 3331 in sequence to form the air guide channel 331. In other words, the first channel 3351 can form three air guide channels 331 together with the three second channels 3331. The three air guide channels 331 correspond one-to-one with the three air intake channels 311 and can form three airflow passages 301 together, thereby achieving precise matching between the airflow passages 301 and the matrix.

[0078] It should be noted that, in some embodiments, the movement of the air guide 335 relative to the main body 333 may include translational movement, rotational movement, and combined movement (including multiple types of movement such as translation and rotation). For ease of understanding, the following embodiments will use translational movement as an example. That is, during the movement of the air guide 335 relative to the main body 333, the first channel 3351 is sequentially connected to multiple second channels 3331 to jointly form the air guide channel 331.

[0079] Furthermore, in some embodiments, the air guide portion 335 includes a first end 3354 and a second end 3355 opposite to each other, and a peripheral wall 3356 located between the first end 3354 and the second end 3355, the peripheral wall 3356 being provided with a through hole 3357. The first channel 3351 includes a first sub-channel 3352 and a second sub-channel 3353, the first sub-channel 3352 being recessed from the first end 3354 toward the second end 3355, and the second sub-channel 3353 being recessed from the outside of the peripheral wall 3356 toward the inside of the air guide portion 335, the first sub-channel 3352 and the second sub-channel 3353 being connected through the through hole 3357.

[0080] Specifically, in some embodiments, the first sub-channel 3352 may be a blind groove, that is, the first sub-channel 3352 is recessed from the first end 3354 toward the second end 3355 and does not penetrate the second end 3355. The through hole 3357 penetrates the bottom wall of the second sub-channel 3353 and communicates with the first sub-channel 3352. Thus, outside air can flow into the second channel 3331 after passing through the first sub-channel 3352, the through hole 3357 and the second sub-channel 3353 in sequence.

[0081] Referring to Figures 9(a) and 9(b), in some embodiments, the cross-sectional dimensions of the plurality of second channels 3331 gradually decrease in the direction of movement of the air guide 335.

[0082] It is understood that in this embodiment, the heating component 500 can be heated in a circumferential manner. The direction of movement of the air guide 335 can be from the second channel 3331 communicating with the outermost matrix layer to the second channel 3331 communicating with the innermost matrix layer. As mentioned above, the aerosol generating matrix 3000 is cylindrical, with the outermost matrix layer having the largest cross-sectional size and the innermost matrix layer having the smallest. Therefore, in the direction of movement of the air guide 335, the cross-sectional size of the multiple second channels 3331 gradually decreases, allowing the intake air volume to precisely match the size of the matrix layer. This not only ensures that the intake air volume meets the atomization requirements of the matrix layer but also reduces the opening size on the main body 333, improving the structural strength of the main body 333. For example, the cross-sectional shape of the multiple second channels 3331 can be approximately the shape of a WIFI signal.

[0083] Referring to Figures 9(a) and 9(b), in some other embodiments, the cross-sectional dimensions of the plurality of second channels 3331 gradually increase in the direction of movement of the air guide 335.

[0084] It is understood that in this embodiment, the heating method of the heating component 500 can be central heating. The direction of movement of the air guide 335 can be from the second channel 3331 communicating with the innermost matrix layer to the second channel 3331 communicating with the outermost matrix layer. As mentioned above, the aerosol generating matrix 3000 is cylindrical, with the outermost matrix layer having the largest cross-sectional size and the innermost matrix layer having the smallest. Therefore, in the direction of movement of the air guide 335, the cross-sectional size of the multiple second channels 3331 gradually increases, allowing the air intake to precisely match the size of the matrix layer. This not only ensures that the air intake meets the atomization requirements of the matrix layer but also reduces the opening size on the main body 333, improving the structural strength of the main body 333. For example, the cross-sectional shape of the multiple second channels 3331 can be approximately the shape of a WIFI signal.

[0085] Referring to Figures 10(a) and 10(b), in some other embodiments, the cross-sectional dimensions of the second channel 3331 are the same as the cross-sectional dimensions of the corresponding intake channel 311.

[0086] Specifically, in some embodiments, when the cross-sectional shape of the air intake channel 311 is the same as the cross-sectional shape of the corresponding matrix portion, that is, when the cross-sectional shape of the air intake channel 311 is annular, the cross-sectional shape of the second channel 3331 is also annular, thereby allowing the outside air to contact the corresponding matrix portion evenly, thereby increasing the atomization amount of the matrix portion and improving the sucking experience.

[0087] In some embodiments, the airway structure 30 further includes a drive member 35, which is connected to the air guide portion 335 and is used to drive the air guide portion 335 to move relative to the main body 333. It should be noted that in some embodiments, the drive member 35 includes, but is not limited to, electromagnets and motors.

[0088] Specifically, in some embodiments, when the user inhales the aerosol generating device 1000, the heating component 500 is activated and heats the corresponding matrix portion, so that the matrix portion is heated to generate aerosol for the user to inhale. When the user stops inhaling the aerosol generating device 1000, the heating component 500 stops heating the matrix portion. At the same time, the driving member 35 drives the air guiding portion 335 to move relative to the main body 333, so that the first sub-channel 3352 communicates with the next second sub-channel 3353 and together form a new air guiding channel 331, and the new air guiding channel 331 can communicate with the next layer of matrix portion. When the user inhales the aerosol generating device 1000 again, the heating component 500 restarts and heats the next layer of matrix portion.

[0089] For example, please refer to Figures 8(a) to 8(f) When the user performs the first suction (as shown in Figure 8(a)), the air guide channel 331 formed by the first channel 3351 and the second channel 3331 is connected to the outermost air intake channel 311, and the outermost air intake channel 311 corresponds to the outermost matrix portion. In this case, the heating component 500 can heat the outermost matrix portion, and the airflow passage 301 formed by the air guide channel 331 and the air intake channel 311 can allow outside air to flow to the outermost matrix portion. When the user performs the second suction (as shown in Figure 8(b)), the driving member 35 drives the air guide portion 335 to move relative to the main body 333, so that the air guide channel 331 formed by the first channel 3351 and the second channel 3331 is connected to the second air intake channel 311, and the second air intake channel 311 corresponds to the second matrix portion. In this case, the heating component 500 can heat the second matrix layer, and the airflow passage 301 formed by the air guide channel 331 and the air intake channel 311 can allow outside air to flow to the second matrix layer; after the user completes the suction of the third port (as shown in Figure 8(c)), the fourth port (as shown in Figure 8(d)), the fifth port (as shown in Figure 8(e))... the nth (n is greater than 5) port, the air guide channel 331 formed by the first channel 3351 and the second channel 3331 can be connected to the innermost air intake channel 311 (as shown in Figure 8(f)), and the innermost air intake channel 311 corresponds to the innermost matrix layer. In this case, the heating component 500 can heat the innermost matrix layer, and the airflow passage 301 formed by the air guide channel 331 and the air intake channel 311 can allow outside air to flow to the innermost matrix layer. Therefore, during the process of the user inhaling the aerosol generating device 1000, the airflow passage 301 can be precisely matched with the matrix section, thereby ensuring that the aerosol generated by the heated aerosol generating matrix 3000 is effectively carried out, increasing the amount of aerosol that can be inhaled and improving the inhalation experience.

[0090] Please see Figures 2 to 4(c)In some embodiments, the main body 333 and the atomizing seat 10 are separate structures.

[0091] Furthermore, in some embodiments, the airway structure 30 further includes a plurality of air guide tubes 37, which are disposed between the air inlet member 31 and the air guide member 33 and are used to connect the corresponding air guide channel 331 and the air inlet channel 311.

[0092] Specifically, multiple air guide tubes 37 correspond one-to-one with multiple air intake channels 311. One end of the air guide tube 37 is connected to the air intake channel 311, and the other end is connected to the air guide channel 331. Thus, outside air can flow sequentially through the air guide channel 331, the inner cavity of the air guide tube 37, and the air intake channel 311 to different positions in the accommodating cavity 11. That is, the air guide channel 331, the inner cavity of the air guide tube 37, and the air intake channel 311 together form an airflow passage 301.

[0093] The arrangement of the air guide tube 37 allows for adaptive adjustment of the air guide component 33, enabling the air guide component 33 to better adapt to the structural layout of the aerosol generating device 1000, facilitating the compact arrangement of other components, and contributing to the miniaturization of the aerosol generating device 1000.

[0094] In some embodiments of this application, the airway structure 30 may further include multiple air intake pipes 39, which are disposed between the air inlet member 31 and the air guide member 33, and are used to connect the corresponding air guide channel 331 and the air inlet channel 311 (annular channel). Specifically, one end of the air intake pipe 39 is connected to the air inlet channel 311, and the other end is connected to the air guide channel 331. Outside air can flow sequentially through the air guide channel 331, the inner cavity of the air intake pipe 39, and the air inlet channel 311 to different positions of the receiving cavity 11. The connection position between the air intake pipe 39 and the air inlet channel 311 is symmetrical with the connection position between the air guide pipe 37 and the air inlet channel 311, thereby ensuring uniform air intake and improving the atomization effect.

[0095] Furthermore, in some embodiments, each air intake channel 311 (annular channel) can be connected to three air intake pipes 39 and one air guide pipe 37, and the connection positions of the three air intake pipes 39 and the air intake channel 311 and the connection positions of the air guide pipe 37 and the air intake channel 311 are evenly distributed, thereby making the air intake uniform and improving the atomization effect.

[0096] Please see Figures 5 to 7In other embodiments, the air intake component 31 and the air guide component 33 are an integral structure. That is, the air intake component 31 and the air guide component 33 are an integral structure manufactured using an integrated molding process. This reduces the space occupied by the air intake component 31 and the air guide component 33, which is beneficial for miniaturizing the atomizer 100. It also improves the stability of the connection between the air intake channel 311 and the air guide channel 331, ensuring the normal operation of the atomizer 100. Furthermore, it reduces the number of parts in the atomizer 100, meaning that there is no need to set up a pipe structure to connect the air intake channel 311 and the air guide channel 331 between the air intake component 31 and the air guide component 33, thereby improving the assembly efficiency of the atomizer 100.
