In other cases, detailed descriptions of well-known systems, devices, circuits and methods are omitted to avoid unnecessary details that hinder the description of the present application.

[0035] The technical solution adopted by the present application to solve its technical problems is:

[0036] Figure 1 An aerosol generating system 1 in some embodiments of the present application is shown, which can include an aerosol generating device 100 and an aerosol generating article 200. The aerosol generating article 200 can be movably inserted into the aerosol generating device 100, which is convenient to take out and replace a new aerosol generating article 200 for continuous use after heating is completed. The aerosol generating device 100 can heat the aerosol generating article 200 inserted therein after being powered on to release aerosol extractives in the aerosol generating article 200 in a non-combustion state.

[0037] The aerosol generating device 100 can be in some embodiments a longitudinal column, which has a columnar accommodation space 22 extending in the axial direction (as shown in Figure 3 The insertion port 11 can be formed on the upper end face of the aerosol generating device 100.

[0038] In some embodiments, the aerosol generating article 200 may be cylindrical. In other embodiments, the aerosol generating article 200 includes an aerosol generating matrix segment 201 and a mouthpiece segment 202 axially connected to the aerosol generating matrix segment 201. The aerosol generating matrix segment 201 may also be elliptical, polygonal, or other columnar shapes. The aerosol generating article 200 includes an aerosol generating matrix, which may include solid materials in strip, sheet, or granular form made from the leaves and / or stems of plants (e.g., tobacco or tea leaves), and aroma components may be further added to the solid material. The length of the aerosol generating matrix segment 201 is equivalent to the length of the receiving space 22, so that when the aerosol generating article 200 is inserted into the receiving space 22, the mouthpiece segment 202 is exposed outside the aerosol generating device 100, allowing the user to inhale aerosols via the mouthpiece segment 202. The diameter of the aerosol generating matrix segment 201 is approximately the same as the diameter of the receiving space 22, so that the aerosol generating matrix segment 201 can be tightly inserted into the receiving space 22. Understandably, the aerosol generating article 200 is not limited to a cylindrical shape, and may also be in other shapes such as an elliptical cylinder or a polygonal cylinder.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the aerosol generating device 100 may include a housing 10, a heating element 20, a power board 40, an electrical connection assembly 30, and a power supply assembly 50. In some embodiments, the housing 10 may be longitudinally elongated. The heating element 20 may be axially disposed within the housing 10 for heating the aerosol generating article 2 inserted therein. The power board 40 and the power supply assembly 50 are respectively installed within the housing 10, and the power board 40 is electrically connected to the power supply assembly 50. The electrical connection assembly 30 electrically connects the power board 40 to the heating element 20. The power board 40 controls the power supply assembly 50 to supply power to the heating element 20 via the electrical connection assembly 30, so that the heating element 20 heats the aerosol generating article 200. The electrical connection assembly 30 reduces the heat conduction from the heating element 20 to the power board 40, providing thermal insulation and buffering to absorb and bear the heat conducted by the heating element 20, thereby ensuring the reliability of the power board 40 under normal operating conditions. The electrical connection assembly 30 can reduce the maximum temperature of the power board 40 from over 120°C to 70°C, meeting the long-term operating temperature requirement of the power board 40 being below 80°C, thereby improving the reliability and service life of the aerosol generating device 100.

[0040] In some embodiments, the heating method adopted by the heating assembly 20 is not limited, for example, it can adopt one or more of resistance heating, electromagnetic heating, infrared heating, laser heating, microwave heating, etc. In some embodiments, the power board 40 can control the conduction and interruption of the circuit between the power supply assembly 50 and the heating assembly 20, and further, the power board 40 can also control the power size of the power supply assembly 50 to the heating assembly 20.

[0041] With reference to the foregoing Figure 2 , the shell 10 is detachably mounted with a shell cover 12 in some embodiments, and the socket 11 is provided on the shell cover 12, the shape of the socket 11 is matched with the cross-sectional shape of the aerosol generating article 200, for example, the socket 11 is circular. Of course, the socket 11 can also be round or other shapes, as long as it can pass through the aerosol generating article 200. The shell cover 12 is connected with the heating assembly 20 to fix the heating assembly 20 in the shell 10. Of course, in other embodiments, the shell cover 12 can also be clamped, spliced or integrally formed with the heating assembly 20.

[0042] As shown in Figure 4 to Figure 5 , the heating assembly 20 can include a base tube 21, a heating unit 23 and a conductive unit 24 respectively arranged on the outer side of the base tube 21, and a mounting seat 25 connected with the base tube 21 in some embodiments, the mounting seat 25 is used to fix the base tube 21 in the shell 10, the heating unit 23 is electrically connected with the conductive unit 24, and the conductive unit 24 is electrically connected with the electrical connection assembly 30. In some embodiments, the heating units 23 can be arranged in a circumferential direction of the base tube 21. Of course, in other embodiments, each heating unit 23 can also be arranged in an axial direction of the base tube 21, or each heating unit 23 can be arranged in both the circumferential direction and the axial direction of the base tube 21. It can be understood that the power supply assembly 50 supplies power to the heating unit 23 through the conductive unit 24, so that the heating unit 23 heats the base tube 21, and then the base tube 21 heats the aerosol generating article 200.

[0043] In some embodiments, the base tube 21 is a hollow structure, and the receiving space 22 is formed in the hollow structure of the base tube 21. The base tube 21 is tubular, for example, circular tubular. In some embodiments, the base tube 21 can adopt a material with high thermal conductivity, so as to better transfer heat to the aerosol generating article 200. In some embodiments, the base tube 21 can adopt a metal material, for example, stainless steel such as 430 or 316L, aluminum, aluminum alloy, etc., which has the advantages of high thermal conductivity, low cost, high strength, etc.

[0044] As shown in Figure 5As shown, the base tube 21 can include a main tube 211 and a flared portion 212 connected to the main tube 211. The flared portion 212 is coaxially arranged with the main tube 211. The aerosol generating article 200 can be smoothly inserted into the main tube 211 via the flared portion 212.

[0045] The cross-sectional area of the flared portion 212 gradually decreases from top to bottom. In addition, a smooth connection can be adopted between the flared portion 212 and the main tube 211, facilitating the insertion of the aerosol generating article 200 and being easy to process and form. The flared portion 212 can be formed with a rounded or beveled opening, or in other words, the inner wall surface of the flared portion 212 can be arc-shaped or beveled. Of course, in other embodiments, the inner wall surface of the flared portion 212 can be partially arc-shaped and partially beveled.

[0046] In some embodiments, the cross-section of the flared portion 212 and the main tube 211 can be circular, the inner diameter of the flared portion 212 gradually decreases from top to bottom, and the inner diameter of the main tube 211 is equal to the inner diameter of the proximal end (the end close to the flared portion 212) of the flared portion 212. In addition, the outer diameter of the flared portion 212 also gradually decreases from top to bottom, and the outer diameter of the main tube 211 is equal to the outer diameter of the proximal end of the flared portion 212.

[0047] With continued reference to Figure 4 and Figure 5 , the heating units 23 are multiple (for example, two, three or more) in some embodiments. Each heating unit 23 is electrically connected to the control circuit. In other words, the multiple heating units 23 are electrically connected to the control circuit in parallel, and the control circuit can control the power-on or power-off of each heating unit 23 respectively. The shapes of the heating units 23 can be the same or different.

[0048] The multiple heating units 23 can be arranged at intervals in the axial and / or circumferential direction of the base tube 21, which can achieve zoned heating of the aerosol generating article 200, enable more concentrated energy in the local area of the aerosol generating article 200, faster smoking effect, shorter preheating time, and lower energy consumption, reduce the maximum discharge current of the power supply assembly 50, and reduce the difficulty of selecting the power supply assembly 50. Compared with only one heating unit 23, the area of the aerosol generating article 200 corresponding to each heating unit 23 of the multiple heating units 23 is smaller, so that the temperature field of the heating area is more uniform, thereby improving the smoking taste of the aerosol generating article 200. In addition, the heating units 23 can heat the aerosol generating article 200 in different areas at different time periods according to the heating situation, thereby improving the consistency during the smoking process.

[0049] In some embodiments, a plurality of heating elements 23 are spaced apart along the axial direction of the base tube 21, and each heating element 23 extends at least partially along the circumferential direction of the base tube 21 in a bent or straight manner. In this embodiment, each heating element 23 extends uniformly in a serpentine shape along the circumferential direction of the base tube 21. The serpentine shape is beneficial for increasing the heating area, while the uniform serpentine shape is beneficial for the uniform distribution of heat in the circumferential direction.

[0050] In some embodiments, a base layer 26 is disposed on the outer surface of the heating unit 23, and a conductive unit 24 is disposed on the outer surface of the base layer 26. The base layer 26 serves to provide insulation and protection. The base layer 26 can support the heating unit 23 and the conductive unit 24 and insulate them from each other. The conductive unit 24 is electrically connected to the electrical connection assembly 30. The conductive unit 24 can be a conductive film, such as a conductive metal film (e.g., a copper film or a silver film) or a non-metallic film formed on the base layer 26 by screen printing. It is understood that in other embodiments, the conductive unit 24 is not limited to being formed on the base layer 26 by screen printing, but can also be fixed to the base layer 26 by adhesive bonding or welding.

[0051] In some embodiments, the conductive unit 24 may also have a high thermal conductivity. For example, the conductive unit 24 may be made of pure silver or a silver alloy. Silver has low resistivity, good electrical conductivity, and high thermal conductivity. With appropriate shape design, it can also play a role in heat equalization, reducing the temperature difference of the heating unit 23 and uniformly distributing heat.

[0052] like Figure 5 As shown, in some embodiments, the mounting base 25 may include a first half-cylinder 251 and a second half-cylinder 252 installed within the housing 10, and the first half-cylinder 251 and the second half-cylinder 252 are spliced, snap-fitted, or integrally formed. Of course, in other embodiments, the first half-cylinder 251 and the second half-cylinder 252 can be sleeved together by a retaining ring 253. Furthermore, the first half-cylinder 251 and the second half-cylinder 252 form a mounting cavity 254 inside to secure the heating element 20, thereby fixing the base tube 21 within the housing 10.

[0053] like Figure 6As shown, the electric connection assembly 30 can include the heat dissipation fin 31, the contact piece 32 and the pogo pin module 33 mounted in the shell 10 respectively in some embodiments. The heat generating assembly 20, the contact piece 32, the heat dissipation fin 31, the pogo pin module 33 and the power board 40 are electrically connected in sequence. It can be understood that the conductive unit 24 of the heat generating assembly 20 is electrically connected with one end of the contact piece 32, the other end of the contact piece 32 is electrically connected with the heat dissipation fin 31, the heat dissipation fin 31 is electrically connected with one end of the pogo pin module 33, and the other end of the pogo pin module 33 is electrically connected with the power board 40. In the process of heat conduction from the heat generating assembly 20 to the power board 40, the heat conduction is buffered, absorbed, borne and dissipated by the heat dissipation fin 31, the contact piece 32 and the pogo pin module 33, and the heat conduction from the heat generating assembly 20 to the power board 40 is reduced, so as to ensure that the power board 40 is used at a normal working temperature.

[0054] As shown in Figure 6 and Figure 7 , the heat dissipation fin 31 can be directly electrically connected with the heat generating assembly 20 and the power board 40 in some embodiments. The heat dissipation fin 31 electrically connects the heat generating assembly 20 and the power board 40. The heat dissipation fin 31 increases the heat dissipation area and improves the heat dissipation efficiency, so as to quickly dissipate the heat transferred by the heat generating assembly 20. In addition, the heat dissipation fin 31 also has the function of transmitting the electric signal of the power board 40. The heat dissipation fin 31 can be made of copper, aluminum, magnesium-aluminum alloy, graphene film, artificial graphite, natural graphite, boron nitride, heat pipe, uniform temperature plate VC and the like.

[0055] Continuing to refer to Figure 7 , the heat dissipation fin 31 includes a main body part 311, a connecting part 312 and a conductive hole 313; the connecting part 312 is located at one end of the main body part 311, the conductive hole 313 is formed on the main body part 311, and the connecting part 312 is electrically connected with the conductive hole 313. The connecting part 312 is used for electrically connecting with the heat generating assembly 20, and the conductive hole 313 is used for electrically connecting with the power board 40. In some embodiments, a sandwich layer is arranged in the main body part 311, and a printed circuit electrically connecting the connecting part 312 and the conductive hole 313 is printed on the sandwich layer. The printed circuit is used for transmitting the electric signal between the heat generating assembly 20 and the power board 40, and the main body part 311 is used for absorbing the heat conduction from the heat generating assembly 20 and dissipating the heat, so as to reduce the heat conduction to the power board 40.

[0056] In some embodiments, the printed circuits can be connected in parallel to achieve step-by-step control of the heating assembly 20, so that the heating assembly 20 heats the aerosol generating article 200 step by step. The printed circuits can also be connected in series to achieve overall control of the heating assembly 20, so that the heating assembly 20 heats the aerosol generating article 200 as a whole. An isolation layer is further provided between the printed circuits and the main body 311, which is used to isolate the electrical signal transmission of the printed circuits from the main body 311, so as to avoid the leakage of electricity during the process of supplying power to the heating assembly by the power supply assembly 50. The main body 311 is made of some materials with good heat dissipation, such as aluminum and copper. In other embodiments, the surface of the main body 311 can also be coated with some materials that help the main body 311 dissipate heat, such as heat dissipation and conduction gel, heat conduction silicone grease, etc.

[0057] As shown in Figure 6 and Figure 7 , the contact piece 32 is used for electrical connection between the heating assembly 20 and the heat dissipation fin 31. The contact piece 32 is connected to the heating assembly 20 and the heat dissipation fin 31 by welding or contact, etc. In some embodiments, one end of the contact piece 32 contacts the heating assembly 20, which can avoid the problems caused by lead processing (welding, etc.), and reduce the total cost of the heating assembly 20. In addition, the contact piece 32 can be separated from the heating assembly 20, so that the use cost can be reduced by replacing part of the assembly. The other end of the contact piece 32 is welded to the connecting portion 312 (such as tin welding or laser welding, etc.) of the heat dissipation fin 31, so that the problem of reduced electrical connection reliability of the heating assembly 20 caused by long-term use in a high-temperature environment can be avoided. The contact piece 32 can be a metal sheet with good electrical conductivity, such as a copper sheet. The contact piece 32 is preferably a spring, but in other embodiments, the contact piece 32 can also be rigid and have no elastic force.

[0058] In some embodiments, a plurality of connecting portions 312 and contact pieces 32 are provided, the plurality of contact pieces 32 are arranged in the mounting seat 25 in an axial uniform interval, and one end of the contact piece 32 is arranged in an axial uniform interval and electrically connected to the heating assembly 20, and the plurality of connecting portions 312 and the other end of the contact piece 32 are sequentially and electrically connected to each other. It can be understood that the heat conducted by the heating assembly 20 is dispersed and conducted, so that the heating assembly 20 is dispersed and emitted through multiple contact pieces 32, thereby reducing the conducted heat of the heating assembly 20.

[0059] As shown in Figure 3 , the contact piece 32 can be partially embedded in the mounting seat 25 in some embodiments. In some embodiments, the contact piece 32 and the mounting seat 25 can be integrally combined by injection molding, so as to form an integrated structure, which can make the fixation of the contact piece 32 more firm and improve the reliability of electrical connection. Of course, in other embodiments, the contact piece 32 can be fixed on the mounting seat 25 by buckling, riveting or other ways.

[0060] As shown in Figure 8As shown, the contact patch 32 can include a body portion 321 embedded in the mounting seat 25 and a first mounting portion 322 and a second mounting portion 323 respectively located at both ends of the body portion 321 in some embodiments. Specifically, the first mounting portion 322 and the second mounting portion 323 are respectively located outside the mounting seat 25, and the first mounting portion 322 and the second mounting portion 323 are respectively electrically connected with the heat generating component 20 and the connecting portion 312 of the heat dissipation fin 31. In other embodiments, the first mounting portion 322 is connected with the heat generating component 20 in a contact manner, and the second mounting portion 323 is welded on the connecting portion 312 of the heat dissipation fin 31 (see Figure 6 ).

[0061] With reference back to Figure 8 , a plurality of through holes 3211 are formed on the body portion 321 of the contact patch 32, the through holes 3211 penetrate the body portion 321 in the thickness direction, and the plurality of through holes 3211 are arranged at intervals in the length direction of the body portion 321. The through holes 3211 can reduce the heat conduction of the contact patch 32. At the same time, the through holes 3211 can improve the bonding strength between the contact patch 32 and the mounting seat 25 when the contact patch 32 and the mounting seat 25 are injection molded, and the injection material can be directly injected into the through holes 3211 to limit the through holes 3211, which can avoid the contact patch 32 from shaking up and down and left and right after long-term use (see Figure 3 ).

[0062] In some embodiments, the through holes 3211 are circular structures, which can also be square structures, and in other embodiments, the circular structure through holes 3211 and the square structure through holes 3211 are arranged at intervals and can be arranged at any position and in any number on the contact patch 32. Of course, in other embodiments, the through holes 3211 can also be other shapes, which can be set according to the use scene and use requirements of the contact patch 32.

[0063] With reference back to Figure 8 , in some embodiments, the body portion 321 of the contact patch 32 can also be provided with a cut groove 3212, which can also reduce heat conduction by locally narrowing the body portion 321. The cut groove 3212 can be arranged at intervals in the length direction of the body portion 321. The cut groove 3212 can extend inward from both sides of the width of the body portion 321 to locally narrow the body portion 321. Specifically, the cut groove 3212 can be symmetrically arranged on both sides of the width of the body portion 321. Of course, in other embodiments, the cut groove 3212 can extend inward from one side of the width of the body portion 321. The cut groove 3212 can also be formed in an S-shaped structure on both sides of the body portion 321, in other words, the cut groove 3212 can be arranged in any order and any structure on one side or both sides of the body portion 321. The cut groove 3212 and the through hole 3211 can form multi-stage filtering on the contact patch 32, reduce the heat conduction of the contact patch 32, and thus reduce the heat conduction of the heat generating component 20 to the outside through the contact patch 32.

[0064] The through holes 3211 and the cut slots 3212 are arranged in the length direction of the contact piece 32, and the plurality of through holes 3211 and the plurality of cut slots 3212 can be arranged in an array on the contact piece 32, or can be arranged at intervals on the contact piece 32. For example, in some embodiments, the body part 321 is provided with four cut slots 3212 arranged at intervals in the length direction, and the body part 321 is provided with six through holes 3211 arranged at intervals in the length direction, and one through hole 3211 can be arranged between every two adjacent cut slots 3212, or a plurality of (for example, two or three) through holes 3211 can be arranged. In other embodiments, four cut slots 3212 (which can also be two cut slots 3212, three cut slots 3212, or other numbers of cut slots 3212) are arranged in the upper half of the contact piece 32 in the length direction of the contact piece 32, and six through holes 3211 (which can also be two through holes 3211, three through holes 3211, or other numbers) are arranged in the lower half of the contact piece 32 in the length direction of the contact piece 32. Similarly, six through holes 3211 (which can also be two through holes 3211, three through holes 3211, or other numbers) are arranged in the upper half of the contact piece 32 in the length direction of the contact piece 32, and four cut slots 3212 (which can also be two cut slots 3212, three cut slots 3212, or other numbers of cut slots 3212) are arranged in the lower half of the contact piece 32 in the length direction of the contact piece 32. The four cut slots 3212 and the six through holes 3211 form a multi-stage filter, thereby reducing the heat conduction of the heat generating component 20 to the outside of the contact piece 32.

[0065] As shown in Figure 6 and Figure 7 In some embodiments, the pogo pin module 33 can be electrically connected to the heat dissipation fins 31 and the power board 40 by clamping, welding, or contact. By conducting the power board 40 and the heat generating component 20 through the pogo pin module 33, the heat conduction of the heat generating component 20 to the power board 40 can also be reduced through the conversion connection mode, thereby ensuring the function and reliability of the power board 40 under normal working temperature conditions.
