However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0045] The technical solution adopted by this utility model to solve its technical problem is:

[0046] Figure 1 An aerosol generation system 100 according to some embodiments of the present invention is shown. The aerosol generation system 100 may include an aerosol generation device 1 and an aerosol generation article 200. The aerosol generation article 200 includes an aerosol generation matrix 201 and a mouthpiece assembly 202. The aerosol generation article 200 is detachably inserted into the aerosol generation device 1, and the mouthpiece assembly 202 is exposed outside the aerosol generation device 1. The aerosol generation device 1 can heat the aerosol generation matrix 201 inserted therein after being powered on, so as to release the aerosol extract in the aerosol generation matrix 201 in a non-combustible state. The user inhales the aerosol extract through the mouthpiece assembly 202.

[0047] like Figure 2 and Figure 3 As shown, the aerosol generation matrix 201 and the nozzle assembly 202 are two independent components. They are structurally and functionally separate, but they work together to achieve the generation and delivery of aerosols.

[0048] The aerosol-generating substrate 201 refers to a substance or combination of substances used to generate aerosol, which can exist in various forms such as, but not limited to, granular, powdered, liquid, or solid forms. The diversity of the aerosol-generating substrate 201 allows users to choose different substrate types according to personal preferences or needs, thereby achieving different aerosol flavors or characteristics. The aerosol-generating device 1 generates aerosol by heating the aerosol-generating substrate 201. The heating method can include, but is not limited to, electrical heating, heat conduction, or other known heating techniques. The device is designed to be compatible with multiple types of aerosol-generating substrates 201, ensuring the versatility and flexibility of the system. In other embodiments, the aerosol-generating substrate 201 can only include a medium segment, or it can include a functional segment (such as a plug) connected to the medium segment. It can be understood that the aerosol-generating article 200 is not limited to a cylindrical shape, but can also be an elliptical cylinder, a polygonal cylinder, or other shapes.

[0049] The mouthpiece assembly 202 is the interface part for users to inhale aerosol, which is designed to connect with the aerosol-generating device 1 and deliver the generated aerosol to the user's mouth. An important technical feature is that the mouthpiece assembly 202 can be used with multiple different aerosol-generating substrates 201. This design allows users to freely switch between different aerosol-generating substrates 201 without changing the mouthpiece assembly 202, thereby achieving a diversified user experience.

[0050] The aerosol-generating substrate 201 and the mouthpiece assembly 202 are separately arranged, and after the aerosol-generating substrate 201 and the mouthpiece assembly 202 are inserted into the aerosol-generating device 1, they can be connected by sleeving, clamping, plugging, contact connection, or indirect connection (the aerosol-generating device 1 guides the flow path of the aerosol generated by the aerosol-generating substrate 201 and makes the aerosol flow to the mouthpiece assembly 202).

[0051] As Figure 4 and Figure 5As shown, the aerosol generating device 1 can be used for a user to smoke aerosol, and can include a main body 10, a cover assembly 20, a connecting assembly 30, a self-locking assembly 40, and a lifting assembly 50 in some embodiments. The main body 10 has a heating cavity 120 for placing an aerosol generating article 201, and an opening 110 is formed in the upper surface of the main body 10 and communicates with the heating cavity 120. The aerosol generating article 201 can be inserted into the heating cavity 120 through the opening 110 and heated to generate aerosol for a user to inhale. The cover assembly 20 is rotatably mounted on the main body 10 through the connecting assembly 30 and can rotate between a first position and a second position. When the cover assembly 20 is in the first position, it covers the opening 110 so that the aerosol generating article 201 cannot be inserted into or pulled out of the opening 110. When the cover assembly 20 is in the second position, it uncovers the opening 110 so that the aerosol generating article 201 can be inserted into or pulled out of the opening 110 (see Figure 6 ). The cover assembly 20 has a mouthpiece insertion hole 210 for inserting a mouthpiece assembly 202, and when the cover assembly 20 is in the first position, the mouthpiece insertion hole 210 communicates with the opening 110. The self-locking assembly 40 is arranged in the main body 10 to lock the cover assembly 20 in the first position. The lifting assembly 50 is mounted on the self-locking assembly 40 and extends into the heating cavity 120. When the self-locking assembly 40 unlocks the cover assembly 20, the lifting assembly 50 moves in the heating cavity 120 along the axis of the heating cavity 120 to push the aerosol generating article 201 in the heating cavity 120 out of the heating cavity 120, thereby automatically pulling out the aerosol generating article 201 and avoiding the user's fingers from touching the heating cavity 120 and causing burns.

[0052] It can be understood that the aerosol generating article 200 is inserted as follows. First, the cover assembly 20 is rotated from the first position to the second position, at which time the cover assembly 20 uncovers the opening 110, and the aerosol generating article 201 can be inserted into the heating cavity 120 through the opening 110. Then, the cover assembly 20 is rotated from the second position to the first position, at which time the cover assembly 20 covers the opening 110, and the mouthpiece insertion hole 210 is coaxial with the axis of the opening 110. At this time, the mouthpiece assembly 202 can be inserted into the mouthpiece insertion hole 210, and the mouthpiece assembly 202 is connected to the end of the aerosol generating article 201 close to the opening 110. In the working state of the aerosol generating device 1, the user can smoke the aerosol generated by the aerosol generating article 201 through the mouthpiece assembly 202.

[0053] In other embodiments, first, the cover assembly 20 is rotated from the first position to the second position (see Figure 6At this point, the cover assembly 20 releases its cover over the opening 110, and the aerosol generating matrix 201 can be inserted into the heating chamber 120 through the opening 110. Then, the nozzle assembly 202 is inserted into the nozzle insertion hole 210 of the cover assembly 20, and the cover assembly 20 is rotated from the second position to the first position. At this point, the cover assembly 20 covers the opening 110, and the nozzle insertion hole 210 is coaxial with the axis of the opening 110. The aerosol generating matrix 201 is connected to the end of the aerosol generating matrix 201 near the opening 110.

[0054] To remove the aerosol-generating product 200: First, pull the nozzle assembly 202 out of the nozzle insertion hole 210, or without removing the nozzle assembly 202, directly rotate the cover assembly 20 from the first position to the second position to remove the cover of the opening 110. At this time, the aerosol-generating matrix 201 can be pulled out from the opening 110. After replacing the aerosol-generating matrix 201, the user can rotate the cover assembly 20 from the second position to the second position.

[0055] In some embodiments, when the cover assembly 20 is in the first position, the cover assembly 20 rotates and covers the opening 110 on the top surface of the main unit 10 to block the opening 110. This prevents the user from being burned when the aerosol generating matrix 201 is heated by contacting the aerosol generating matrix 201 or the high-temperature area of ​​the main unit 10.

[0056] like Figure 4 and Figure 7 As shown, in some embodiments, the host 10 may include a housing 11, a heating element 12, a main control component 13, and a power supply component 14. In some embodiments, the housing 11 may be square tubular. The heating element 12 is axially disposed within the housing 11 for heating the aerosol generating matrix 201. The heating element 12 is cylindrical, and a heating chamber 120 is axially disposed on the heating element 12. The main control component 13 and the power supply component 14 are respectively installed within the housing 11, and the heating element 12, the main control component 13, and the power supply component 14 are electrically connected to each other. The main control component 13 controls the power supply component 14 to supply power to the heating element 12, so that the heating element 12 heats the aerosol generating matrix 201.

[0057] For reference Figure 8In some embodiments, the housing 11 can include an outer frame 113 and an inner frame 114 longitudinally sleeved in the outer frame 113, and the opening 110 is formed in the upper surface of the inner frame 114. In some embodiments, the opening 110 is conical, and the inner diameter of the opening 110 gradually decreases from top to bottom, so that the aerosol generating substrate 201 is smoothly inserted into the heating cavity 120. In addition, the top end of the opening 110 can be provided with a rounded or beveled opening, that is, the inner wall surface of the opening 110 can be arc-shaped or beveled. Of course, in other embodiments, the inner wall surface of the opening 110 can be partially arc-shaped and partially beveled.

[0058] In some embodiments, the housing 11 can further include a first magnet 111 mounted in the inner frame 114 near the first opening 110 and a host connection plate 112 mounted on the upper surface of the inner frame 114 (see Figure 7 The host connection plate 112 is electrically connected to the host assembly 13.

[0059] As Figure 9 and Figure 10 In some embodiments, the heating assembly 12 can further include a heating cavity 121 and a fixing seat 122. The fixing seat 122 is mounted on the inner wall of the inner frame 114, and the heating cavity 121 is longitudinally mounted on the fixing seat 122. The heating cavity 121 is coaxially arranged with the opening 110, and the heating cavity 121 is electrically connected to the host assembly 13. It can be understood that the heating cavity 121 is fixed in the inner frame 114 by the fixing seat 122 and located below the opening 110, so that the aerosol generating substrate 201 is longitudinally inserted into the heating cavity 121 from the opening 110. Then, the host assembly 13 controls the power supply assembly 14 to heat the aerosol generating substrate 201 in the heating cavity 121.

[0060] Referring to Figure 11 In some embodiments, the heating cavity 121 can include a base tube 1211, an isolation layer 1212, and a heating structure 1213. The base tube 1211 is a hollow structure, and the heating cavity 120 is formed in the hollow structure of the base tube 1211. The heating structure 1213 can be arranged on the inner side and / or outer side of the base tube 1211, and the isolation layer 1212 is arranged between the base tube 1211 and the heating structure 1213. The base tube 1211 can be made of a material with high thermal conductivity, so as to better transfer the heat of the heating structure 1213 to the aerosol generating substrate 201. In some embodiments, the base tube 1211 can be made of a metal material, such as stainless steel (e.g., 430 or 316L), aluminum, aluminum alloy, etc. The metal material has the advantages of high thermal conductivity, low cost, and high strength.

[0061] Accordingly, the base tube 1211 is insulated from the heat generating structure 1213 by the isolation layer 1212. The isolation layer 1212 can be made of an insulating material with a relatively high thermal conductivity, so as to better transfer the heat from the heat generating structure 1213 to the aerosol generating substrate 201. The isolation layer 1212 can be an insulating glaze layer (e.g., a glass glaze layer), which can be prepared by dip coating, sintering, or the like. In addition, by providing the isolation layer 1212, the strength of the base tube 1211 can be improved, which is conducive to the thinning design of the base tube 1211. Understandably, in other embodiments, the inner side of the base tube 1211 can also be provided with the isolation layer 1212.

[0062] Of course, in other embodiments, the base tube 1211 can also be made of an insulating material with a relatively high thermal conductivity, such as a ceramic material (e.g., zirconium oxide), a non-metallic material such as quartz glass, or the like. In this way, the outer side or the inner side of the base tube 1211 can or can not be provided with the isolation layer 1212.

[0063] Continuing to refer to Figure 11 In some embodiments, the base tube 1211 can include a main tube 12111 and a flared portion 12112 provided at one end of the main tube 12111. The flared portion 12112 and the main tube 12111 are coaxially arranged. The aerosol generating substrate 201 can be smoothly inserted into the main tube 12111 via the flared portion 12112. The cross-sectional area of the flared portion 12112 gradually decreases from top to bottom. In addition, the flared portion 12112 and the main tube 12111 can be connected smoothly, which facilitates the insertion of the aerosol generating article 2 and is easy to process and form. The flared portion 12112 can be formed with a rounded or beveled opening, or in other words, the inner wall surface of the flared portion 12112 can be curved or beveled. Of course, in other embodiments, the inner wall surface of the flared portion 12112 can be partially curved and partially beveled.

[0064] In some embodiments, the cross-section of the flared portion 12112 and the main tube 12111 can be circular, the inner diameter of the flared portion 12112 gradually decreases from top to bottom, and the inner diameter of the main tube 12111 is equal to the inner diameter of the proximal end (i.e., the end close to the flared portion 12112) of the flared portion 12112. In addition, the outer diameter of the flared portion 12112 also gradually decreases from top to bottom, and the outer diameter of the main tube 12111 is equal to the outer diameter of the proximal end of the flared portion 12112.

[0065] Again referring to Figure 11In some embodiments, the heating structure 1213 can be arranged on the inner side of the base tube 1211. In other embodiments, the heating structure 1213 can also be arranged on the outer side of the base tube 1211. In this case, the base tube 1211 can be made of a material with a low thermal conductivity, which is conducive to reducing the heat dissipation of the heating structure 1213 and reducing heat loss. In other embodiments, the heating structure 1213 can be partially arranged on the outer side of the base tube 1211 and partially arranged on the inner side of the base tube 1211.

[0066] With continued reference to Figure 11 In some embodiments, the heating structure 1213 can include a substrate layer 12132, at least one heating unit 12131 arranged on the inner side of the substrate layer 12132, and at least two conductive units 12133 arranged on the outer side of the substrate layer 12132. Each heating unit 12131 is electrically connected to two conductive units 12133, and in turn to the control circuit. Each heating unit 12131 is electrically connected to two conductive units 12133, respectively. Each heating unit 12131 can be arranged in a circumferential direction of the base tube 1211. Of course, in other embodiments, each heating unit 12131 can be arranged in an axial direction of the base tube 1211, or each heating unit 12131 can be arranged in both the circumferential direction and the axial direction of the base tube 1211.

[0067] The substrate layer 12132 is made of an insulating material. In some embodiments, the substrate layer 12132 can be a glass film strip or a ceramic film strip formed by flow casting or the like. The substrate layer 12132 can play a role of insulation and protection. The substrate layer 12132 can carry the heating unit 12131 and the conductive unit 12133 and insulate and separate the heating unit 12131 and the conductive unit 12133, and can also separate the heating unit 12131 from the outside air, thereby reducing the erosion of oxygen and impurities on the heating unit 12131. The connection between the at least one heating unit 12131 and the at least two conductive units 12133 can be achieved by punching holes (not shown) on the substrate layer 12132.

[0068] The heating unit 12131 includes a conductive material, which can convert electrical energy into heat energy by using the Joule heating effect generated when an electric current passes through the conductive material. In some embodiments, the heating unit 12131 can include a metal material, or a mixture of a metal material and a non-metal material (such as glass). The at least two conductive units 12133 are used to be electrically connected to the master control assembly 13, thereby connecting the at least one heating unit 12131 to the master control assembly 13. The conductive unit 12133 can be connected to the master control assembly 13 by a lead, a conductive sheet, an electrode column, or the like.

[0069] By arranging the heating unit 12131 and the conductive unit 12133 on different sides of the base layer 12132, the arrangement space of at least one heating unit 12131 can be increased, the heating area can be increased, the heating consistency can be improved, and the smoking taste consistency can be improved. The heating unit 12131 can be a heating film formed by screen printing or deposition, etc. Of course, in other embodiments, the heating unit 12131 can also be a net, array or fabric formed by conductive wires or conductive sheets.

[0070] The conductive unit 12133 can be a conductive film, for example, a conductive metal film (such as a copper film or a silver film) or a non-metal film formed on the base layer 12132 by screen printing. It can be understood that in other embodiments, the conductive unit 12133 can not be limited to being formed on the base layer 12132 by screen printing, but can also be fixed on the base layer 12132 by adhesion or by welding.

[0071] In some embodiments, the conductive unit 12133 can also have a high thermal conductivity, for example, the conductive unit 12133 is a pure silver or silver alloy material, the silver material has a small resistivity, good electrical conductivity, and a high thermal conductivity. Through suitable shape design, it can also play a role in heat equalization, reducing the temperature difference of the heating unit 12131 and uniforming the heat.

[0072] As shown in FIG. 12A, the heating unit 12131 is arranged on the base layer 12132. The heating unit 12131 can be arranged on the base layer 12132 in a plurality of ways, for example, the heating unit 12131 can be arranged on the base layer 12132 by screen printing, or the heating unit 12131 can be arranged on the base layer 12132 by deposition, etc. Figure 11 It is shown that the heating unit 12131 has a plurality (for example, two, three or more than three) in some embodiments. Each heating unit 12131 is electrically connected to the control circuit. It can also be said that the plurality of heating units 12131 are electrically connected to the control circuit in a parallel manner, and the control circuit can control the power-on or power-off of each heating unit 12131 respectively. The shape of each heating unit 12131 can be the same or different.

[0073] The plurality of heating units 12131 can be arranged in the axial and / or circumferential direction of the base pipe 1211 to realize zoned heating of the aerosol generating substrate 201, so that the local energy of the aerosol generating substrate 201 is more concentrated, the smoking effect is faster, the preheating time is shortened, the energy consumption is reduced, the maximum discharge current of the power supply assembly 14 is reduced, and the selection difficulty of the power supply assembly 14 is reduced. Compared with only one heating unit 12131, the substrate area corresponding to each heating unit 12131 of the plurality of heating units 12131 is smaller, so that the temperature field of the heating area is more uniform, and the smoking taste of the aerosol generating substrate 201 can be improved. In addition, the heating unit 12131 can heat the aerosol generating substrate 201 in different regions at different time periods according to the heating condition, thereby improving the consistency during the smoking process.

[0074] In some examples, the plurality of heat generating units 12131 are arranged in an axial direction of the base tube 1211, and each heat generating unit 12131 extends at least partially along a circumferential direction of the base tube 1211 in a meandering manner or in a straight line. In this embodiment, each heat generating unit 12131 extends in a uniform meandering manner along the circumferential direction of the base tube 1211. The meandering shape is conducive to increasing the heat generating area, and the uniform meandering shape is conducive to uniform distribution of heat in the circumferential direction.

[0075] As Figure 12 and Figure 13 In some examples, the cover assembly 20 can include a flip cover 21, a second magnet 22, and an interaction assembly 23. The flip cover 21 is rotatably mounted on the top of the housing 11 to cover the opening 110, and a mouthpiece insertion hole 210 is formed in the flip cover 21. The second magnet 22 is mounted on the flip cover 21 and magnetically attracted to the first magnet 111 to magnetically hold the flip cover 21 in the first position. The interaction assembly 23 is mounted in the flip cover 21 and electrically connected to the host connection plate 112 to enable the host assembly 13 to control the interaction assembly 23. Understandably, the flip cover 21 in the first position avoids the user's fingers from touching the heating cavity 121 and operating the aerosol generating substrate 201, thereby preventing the user's fingers from being scalded and solving the safety problem. The flip cover 21 can be rotated between the first position and the second position. When the flip cover 21 is rotated to the first position, the first magnet 111 and the second magnet 22 are magnetically attracted to each other, thereby avoiding the flip cover 21 from moving due to the shaking of the aerosol generating device 1 and increasing the stability between the flip cover 21 in the first position and the housing 11. The interaction assembly 23 can realize visual interaction, such as light interaction, a small screen, and the like, according to the detection of the working state of the aerosol generating device 1, thereby increasing the rich interaction and operation experience.

[0076] In some examples, the flip cover 21 can include an outer shell 211, an inner shell 212, a decorative cover 213, a decorative piece 214, and a decorative cover silicone 215. The outer shell 211 is sleeved on the inner shell 212, the inner shell 212 is rotatably mounted on the housing 11 by the connection assembly 30, the decorative piece 214 is mounted on the top of the outer shell 211, the decorative cover 213 is mounted on the decorative piece 214, the decorative cover silicone 215 is mounted between the inner shell 212 and the decorative cover 213, the mouthpiece insertion hole 210 is longitudinally formed in the outer shell 211 and the inner shell 212, and the second magnet 22 is mounted on one side of the inner shell 212 close to the opening 110, or the mouthpiece insertion hole 210 is longitudinally formed in the decorative cover 214 and the inner shell 212. Understandably, the outer shell 211 and the inner shell 212 have a rectangular structure, and the cross-sectional area of the outer shell 211 is larger than that of the housing 11, so as to cover the opening 110 on the upper surface of the housing 11.

[0077] Continuing to refer to Figure 12, the inner wall of the shell 211 is provided with a clamping groove 2110 in some embodiments for matching the self-locking assembly 40, the clamping groove 2110 is used for the self-locking assembly 40 to lock the flip cover 21 in the first position, avoiding the displacement of the flip cover 21 in the first position due to shaking and other phenomena. The inner shell 212 is provided with a limiting step 2121 in some embodiments, and the end of the limiting step 2121 extends into the suction nozzle insertion hole 210, which is used to limit the suction nozzle assembly 202 when it is inserted into the suction nozzle insertion hole 210. It can be understood that when the suction nozzle assembly 202 is inserted into the suction nozzle insertion hole 210, the suction nozzle assembly 202 stops inserting when it encounters the upper surface of the limiting step 2121, at this time the suction nozzle assembly 202 indicates that it has been inserted in place, and the suction nozzle assembly 202 has been connected with the aerosol generating substrate 201. The suction nozzle assembly 202 can be freely inserted and removed in the suction nozzle insertion hole 210, whether the aerosol generating substrate 201 is heated or not, the suction nozzle assembly 202 can be removed from the suction nozzle insertion hole 210. However, the aerosol generating substrate 201 will expand during heating, and the limiting step 2121 at the bottom will limit the aerosol generating substrate 201, so that the aerosol generating substrate 201 will not be taken out even if the suction nozzle assembly 202 is replaced.

[0078] In some embodiments, the inner diameter of the suction nozzle insertion hole 210 is equal to the inner diameter of the heating cavity 120, and the inner diameter of the limiting step 2121 is smaller than the inner diameter of the heating cavity 120. In some embodiments, the aerosol generating substrate 201 will be in interference fit with the heating cavity 120 after heating and expansion, the friction between them will increase, the stability of the aerosol generating substrate 201 inserted into the heating cavity 120 will be better, and the movement of the aerosol generating substrate 201 caused by the removal of the suction nozzle assembly 202 will be reduced.

[0079] The upper surface of the decorative cover 213 is rounded in some embodiments (at the top end of the suction nozzle insertion hole 210), so that the suction nozzle assembly 202 can be inserted into the suction nozzle insertion hole 210. Of course, in other embodiments, the upper surface of the decorative cover 213 can also be arc-shaped or beveled.

[0080] As Figure 12 and Figure 13As shown, the interaction assembly 23 can include a light plate 231, a light uniform plate 232, a single mirror 233, and a spring needle 234 in some embodiments; the light plate 231 and the spring needle 234 for displaying the state of the aerosol generating device 1 are respectively installed in the flip cover 21, and the two ends of the light plate 231 and the spring needle 234 are respectively electrically connected with the light plate 231 and the host connection plate 112, and the light uniform plate 232 and the single mirror 233 are both installed on the light plate 231. It can be understood that the host control assembly 13 is electrically connected with the light plate 231 through the spring needle 234, so as to control the power supply assembly 14 to supply power to the light plate 231, so that the light plate 231 is lighted. The light uniform plate 232 uniformly diffuses the light emitted by the light plate 231 to the surrounding, so as to facilitate the user to watch. The single mirror 233 transmits the light of the light plate 231 to the outside of the flip cover 21, so as to facilitate the user to watch from the outside of the flip cover 21. The spring needle 234 is in surface contact type electrical connection with the host 10 connection plate 112, so as to facilitate the flip cover 21 to rotate from the first position to the second position, avoiding the wire connection, and the wire breakage caused by the long-term rotation of the flip cover 21. In addition, the surface contact electrical connection of the spring needle 234 can be separated from the host 10, facilitating the replacement of the cover assembly 20 or the interaction assembly 23, so that the cost can be reduced by replacing part of the assembly. In some embodiments, the light plate 231 can have multiple colors or brightness, and different visual interactions can be realized by different light colors or brightness. In other embodiments, the light plate 231 is not limited to the abyss lamp, the indicator light, and can also be a small display screen and the like.

It can be understood that the inner shell 212 rotates between the first position and the second position through the rotating shaft 31, and the first elastic member 32 elastically retains the inner shell 212 in the first position or the second position. The flip cover 21 is always subjected to the force of the first elastic member 32 pointing to the host 10 when in the closed state. The flip cover 21 is always subjected to the force (force in the opposite direction of the closed state) pointing to the opposite direction of the host 10 when in the fully open state. In addition, the flip cover 21 also has a critical state, that is, the flip cover 21 is located between the first position and the second position, and the elastic force direction of the first elastic member 32 is in a line with the rotating shaft 31 and the fulcrum of the first elastic member 32. At this time, it is in a critical value, and the flip cover 21 is not subjected to the force in the opening or closing direction. In some embodiments, the first elastic member 32 is a coil spring, and of course, compression springs, tension springs and other modes can also be used.

[0082] As shown in Figure 10 and Figure 14As shown, the self-locking assembly 40 can include a lock tongue 41, a second elastic member 42, and a driving assembly 43 in some embodiments. The lock tongue 41 is slidingly installed in the housing 11 and is movable back and forth between a third position and a fourth position. When the lock tongue 41 is in the third position, the lock tongue 41 extends out of the housing 11 and is buckled in the clamping groove 2110 of the shell 211 in the first position to lock the flip cover 21 in the first position. When the lock tongue 41 is in the fourth position, the lock tongue 41 extends into the housing 11 to unlock the flip cover 21 in the first position. The two ends of the second elastic member 42 are connected with the housing 11 and the lock tongue 41 respectively to elastically keep the lock tongue 41 in the third position. The driving assembly 43 is installed in the housing 11 and connected with the lock tongue 41 for driving the lock tongue 41 to move from the third position to the fourth position against the elastic force of the second elastic member 42.

[0083] It can be understood that the driving assembly 43 drives the lock tongue 41 to move between the third position and the fourth position. When the lock tongue 41 is in the third position, the lock tongue 41 extends out of the housing 11 and is buckled in the clamping groove 2110 of the flip cover 21 in the first position, at which time the flip cover 21 is locked and cannot be rotated. When the lock tongue 41 is in the fourth position, the driving assembly 43 drives the lock tongue 41 to move into the housing 11, and the flip cover 21 loses the limit, at which time the flip cover 21 can be moved from the first position to the second position.

Understandably, the top rod 51 can pass through the fixing seat 122 and extend into the heating cavity 120 through the fixing member 52 arranged on the mounting portion 4324 of the bracket 432. When the aerosol generating substrate 201 is heated, the top rod 51 is located at the inner bottom of the heating cavity 120. When the bracket 432 moves upward, the top rod 51 moves upward together with the bracket 432, thereby pushing the aerosol generating substrate 201 out of the heating cavity 120.

[0089] The aerosol generating device 1 will be further described in combination with the use process.
