[0041] The various specific technical features and embodiments described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different specific technical features / embodiments can form different embodiments by combination. In order to avoid unnecessary repetition, various possible combinations of the various specific technical features / embodiments in the present application are not described again. In addition, the term "first" is only for descriptive purposes and cannot be understood as indicating or implying relative importance. The present application will be further described in detail below in conjunction with the drawings and specific embodiments.
[0042] Please refer to Figures 1 to 11 The aerosol generating device 100 provided by the embodiments of the present application includes a liquid storage assembly 1, an atomization core 2, and a fixing support 3. The liquid storage assembly 1 is formed with a liquid storage cavity 1a for storing an aerosol generating substrate. The atomization core 2 atomizes the aerosol generating substrate into an aerosol. The fixing support 3 includes a spring sheet 31. The atomization core 2 has a thickness direction, and the spring sheet 31 is in abutting engagement with the atomization core 2 on one side along the thickness direction.
[0043] The atomization core 2 is arranged in the liquid storage cavity 1a and can be in contact with the aerosol generating substrate and atomize the aerosol generating substrate into an aerosol by heating or the like for a user to draw.
[0044] For example, as shown in Figure 3 The fixing support 3 includes a limiting space 3a, and at least part of the atomization core 2 is located in the limiting space 3a. The limiting space 3a can be used to limit the movement of the atomization core 2 to fix the atomization core 2. For example, the part of the atomization core 2 located in the limiting space 3a is substantially the same as the shape of the limiting space 3a. In this way, the surface of the atomization core 2 is closely fitted with the surface of the fixing support 3, and the gap between them is small, which can prevent the atomization core 2 from shaking and shifting in the limiting space 3a.
[0045] At least part of the atomization core 2 located in the limiting space 3a means that part of the atomization core 2 can be located in the limiting space 3a, or the entire atomization core 2 can be located in the limiting space 3a.
[0046] For example, as shown in Figure 3The fixed support 3 is formed with an inlet and outlet 3b in communication with the limiting space 3a, and the atomization core 2 can enter or leave the limiting space 3a through the inlet and outlet 3b, so that the atomization core 2 is conveniently assembled.
[0047] The elastic sheet 31 is a structure capable of elastic deformation, for example, can be a structure prepared from an elastic material. The elastic material refers to a material capable of elastic deformation such as bendable, foldable, twistable, compressible and / or stretchable, and capable of restoring the deformation within a certain limit.
[0048] The abutting fit of the elastic sheet 31 and the atomization core 2 means that the atomization core 2 and the elastic sheet 31 are precisely positioned and fitted by contacting (abutting) each other when assembled. In this way, the elastic force of the elastic sheet 31 is applied to the atomization core 2, and the elastic sheet 31 abuts against the atomization core 2, which can improve the connection stability of the atomization core 2 and the fixed support 3.
[0049] The aerosol atomization device provided by the embodiments of the present application has the following advantages. On the one hand, the elastic sheet 31 and the atomization core 2 are abuttingly fitted, and the elastic force of the elastic sheet 31 is applied to the atomization core 2, which can improve the connection stability of the atomization core 2 and the fixed support 3 and reduce the difficulty of assembly and disassembly. On the other hand, the atomization core 2 can be fixed by the fixed support 3 in the present application, which is convenient and fast, can simplify the assembly process of the atomization core 2 and the required parts, reduce the production cost, and improve the production efficiency.
[0050] In some embodiments, the fixed support 3 is an integrally formed structure, which means that the fixed support 3 is manufactured by an integrally forming process, so that the assembly steps of the fixed support 3 can be reduced and the stability of the fixed support 3 can be improved.
[0051] In other embodiments, the fixed support 3 can also be a split structure. That is, the fixed support 3 can be assembled and formed by combining two or more parts.
[0052] In an embodiment, the fixed support 3 can be a structure prepared from an elastic material. For example, the fixed support 3 can be prepared from a metal material. In this way, the fixed support 3 and the atomization core 2 are in flexible contact, and the elastic force of the fixed support 3 can slow down the force transmitted to the atomization core 2, which can better protect the atomization core 2.
[0053] In some embodiments, please refer to Figure 2 and Figure 7 The liquid storage assembly 1 includes a buffer structure 11 arranged in the liquid storage cavity 1a, and the buffer structure 11 can absorb and release the aerosol generating substrate.
[0054] The aerosol generating substrate in the present application is in a liquid state. The buffer structure 11 can absorb the aerosol generating substrate. In this way, the buffer structure 11 plays a role of locking the liquid, which can prevent the aerosol generating substrate from leaking out of the liquid storage cavity 1a, thereby reducing the risk of liquid leakage. During the user's puffing of the aerosol, the aerosol generating substrate absorbed by the buffer structure 11 is released to the atomization core 2, and the atomization core 2 atomizes the liquid aerosol generating substrate into an aerosol.
[0055] In some embodiments, the buffer structure 11 can be a flexible structure having a plurality of holes, and the buffer structure 11 can absorb and release the aerosol generating substrate through capillary action.
[0056] For example, the material of the buffer structure 11 includes one or more of non-woven fabric, linen, and wood pulp cotton. For example, the buffer structure 11 can be prepared by using wood pulp cotton.
[0057] In some embodiments, referring to Figure 2 , at least part of the buffer structure 11 is located on the side of the atomization core 2 away from the spring sheet 31, and the elastic force of the spring sheet 31 makes the atomization core 2 abut against the buffer structure 11. In this way, the surfaces of the atomization core 2 and the buffer structure 11 can be closely attached, the aerosol generating substrate can be directly guided from the buffer structure 11 to the atomization core 2, the transmission path of the aerosol generating substrate is shortened, the atomization efficiency is improved, and the heat energy utilization rate of the atomization core 2 is effectively improved, thereby reducing energy loss.
[0058] In some embodiments, referring to Figures 3 to 5 , the spring sheet 31 is formed with a protrusion 311 facing the atomization core 2, and the protrusion 311 abuts against the atomization core 2. For example, the surface of the protrusion 311 facing the atomization core 2 can be a smooth convex arc surface. On the one hand, the protrusion 311 can increase the contact area between the spring sheet 31 and the atomization core 2, thereby increasing the elastic force of the spring sheet 31 applied to the atomization core 2 and improving the stability of the atomization core 2. On the other hand, the spring sheet 31 and the atomization core 2 are in flexible contact. In this way, the protrusion 311 can deform or bend according to the outer surface of the atomization core 2, which can ensure the stability of the atomization core 2 while not damaging the internal structure of the atomization core 2, so that the atomization core 2 can maintain good conduction performance for the aerosol generating substrate.
[0059] In some embodiments, referring to Figure 4 and Figure 5 , the fixing support 3 includes a stop structure 30, the stop structure abuts against the atomization core 2, and at least part of the stop structure 30 is located on a different side of the atomization core 2 from the spring sheet 31. In this way, the stop structure 30 and the spring sheet 31 can respectively limit the movement of the atomization core 2 in different directions, thereby enhancing the stability of the atomization core 2.
[0060] At least part of the stop structure 30 and the elastic piece 31 are respectively located at different sides of the atomizing core 2, which means that part of the stop structure 30 and the elastic piece 31 are respectively located at different sides of the atomizing core 2, or the entire stop structure 30 and the elastic piece 31 are respectively located at different sides of the atomizing core 2.
[0061] In an embodiment, referring to Figure 4 and Figure 5 , the stop structure 30 comprises a stop piece 32, the atomizing core 2 is provided with the elastic piece 31 on at least one side in the thickness direction, the atomizing core 2 is provided with the stop piece 32 on at least one side in the first direction, and the thickness direction and the first direction intersect.
[0062] The atomizing core 2 is provided with the elastic piece 31 on at least one side in the thickness direction, which means that the atomizing core 2 is provided with the elastic piece 31 on one side in the thickness direction, or the atomizing core 2 is provided with the elastic piece 31 on both sides in the thickness direction.
[0063] The atomizing core 2 is provided with the stop piece 32 on at least one side in the first direction, which means that the atomizing core 2 is provided with the stop piece 32 on one side in the first direction, or the atomizing core 2 is provided with the stop piece 32 on both sides in the first direction.
[0064] In this embodiment, the elastic piece 31 and the stop piece 32 are respectively located at different sides of the atomizing core 2. The elastic piece 31 can limit the movement of the atomizing core 2 in the thickness direction, and the stop piece 32 can limit the movement of the atomizing core 2 in the first direction, so that the stability of the atomizing core 2 can be further improved.
[0065] It should be noted that the thickness direction and the first direction intersect, which means that the thickness direction and the first direction intersect obliquely or perpendicularly.
[0066] In some embodiments, the atomizing core 2 is provided with the elastic piece 31 on opposite sides in the thickness direction, and the atomizing core 2 is provided with the stop piece 32 on at least one side in the first direction. In other embodiments, the atomizing core 2 is provided with the elastic piece 31 on at least one side in the thickness direction, and the atomizing core 2 is provided with the stop piece 32 on opposite sides in the first direction. In other embodiments, the atomizing core 2 is provided with the elastic piece 31 on opposite ends in the thickness direction, and the atomizing core 2 is provided with the stop piece 32 on opposite ends in the first direction.
[0067] In an embodiment, the stop piece 32 is substantially in the form of a sheet, so that the contact area of the stop piece 32 and the atomizing core 2 can be increased to improve the stability of the atomizing core 2.
[0068] In some embodiments, referring to Figure 3 and Figure 6The stop structure 30 comprises a limiting piece 33. The elastic sheet 31 and the limiting piece 33 jointly define a limiting space 3a. The elastic sheet 31 and the limiting piece 33 abut against the opposite ends of the atomization core 2 along the thickness direction.
[0069] For example, please refer to Figure 3 and Figure 6 The elastic sheet 31 and the limiting piece 33 abut against the opposite ends of the atomization core 2 along the thickness direction. The inlet and outlet 3b are open towards the top side. In this way, the elastic sheet 31 and the limiting piece 33 jointly limit the movement of the atomization core 2 along the thickness direction, and both of them play a good fixing role. In addition, during the assembly of the atomization core 2, the atomization core 2 can be moved from the top side to the bottom side and enter the limiting space 3a through the inlet and outlet 3b, and the installation is convenient.
[0070] In an embodiment, the limiting piece 33 is substantially in the shape of a sheet. In this way, the contact area of the limiting piece 33 and the atomization core 2 can be increased, and the stability of the atomization core 2 can be improved.
[0071] In some embodiments, please refer to Figure 3 and Figure 6 The limiting piece 33 is connected with the stop piece 32. In this way, the overall stability of the fixing support 3 can be improved, and the manufacturing difficulty of the fixing support 3 can be reduced, which is convenient for production.
[0072] In some embodiments, please refer to Figure 2 and Figure 7 The aerosol generating device 100 comprises a conductive piece 4. The conductive piece 4 is electrically connected with the fixing support 3. The conductive piece 4 is used to provide electric energy. In this embodiment, the conductive piece 4 is electrically connected with the fixing support 3, and the fixing support 3 has electrical conductivity. In this way, on the one hand, the conductive piece 4 transmits external electric energy to the atomization core 2 through the fixing support 3. The atomization core 2 can heat the aerosol generating substrate to generate aerosol in the energized state. On the other hand, it is not necessary to additionally set a conductive structure such as a wire to transmit electric energy, thereby reducing the number of components, and reducing the production cost and assembly difficulty.
[0073] The specific material of the fixing support 3 is not limited. For example, the fixing support 3 can be made of metal material, which has good electrical conductivity. For example, it can be brass, SUS430 stainless steel or 1018 steel, etc.
[0074] In an embodiment, the conductive piece 4 can be a thimble.
[0075] In an embodiment, the conductive piece 4 is welded with the fixing support 3. In this way, the connection stability of the conductive piece 4 and the fixing support 3 can be improved. In addition, the electrical conductivity between the conductive piece 4 and the fixing support 3 can be improved to some extent, and the operation reliability of the aerosol generating substrate can be improved.
[0076] In some embodiments, please refer toFigures 4 to 6 The two conductive pieces 4 are respectively electrically connected to the two fixing supports 3, and the two conductive pieces 4 are arranged at intervals along the first direction, that is, the two fixing supports 3 are arranged at intervals along the first direction, and the two ends of the atomization core 2 along the first direction are respectively located in the limiting spaces 3a of the two fixing supports 3. In this way, on the one hand, the end of the atomization core 2 is accommodated in the limiting space 3a, which not only can improve the stability of the atomization core 2, but also can prevent the end of the atomization core 2 from being damaged due to collision with other parts. On the other hand, the two fixing supports 3 do not contact, and no additional current-carrying loop is formed between the two fixing supports 3, so that the current cannot be directly transmitted through the two fixing supports 3, thereby preventing short circuit and damage to the aerosol generating device 100.
[0077] For example, referring to Figure 4 The two conductive pieces 4 are respectively electrically connected to the two fixing supports 3, and the two conductive pieces 4 are arranged at intervals along the first direction, that is, the two fixing supports 3 are arranged at intervals along the first direction, and the two ends of the atomization core 2 along the first direction are respectively located in the limiting spaces 3a of the two fixing supports 3. In this way, on the one hand, the end of the atomization core 2 is accommodated in the limiting space 3a, which not only can improve the stability of the atomization core 2, but also can prevent the end of the atomization core 2 from being damaged due to collision with other parts. On the other hand, the two fixing supports 3 do not contact, and no additional current-carrying loop is formed between the two fixing supports 3, so that the current cannot be directly transmitted through the two fixing supports 3, thereby preventing short circuit and damage to the aerosol generating device 100.
[0078] In some embodiments, referring to Figure 4 The two fixing supports 3 are respectively provided with a stop piece 32, and the stop pieces 32 of the two fixing supports 3 respectively abut the two ends of the atomization core 2 along the first direction.
[0079] In some embodiments, referring to Figure 4 and Figure 5 The atomization core 2 comprises a base body 21 and a heating body 22, at least part of the heating body 22 is arranged on the surface of the base body 21, and the spring piece 31 abuts the heating body 22. For example, the base body 21 has an atomization surface, the heating body 22 is arranged on the atomization surface, the base body 21 can guide the aerosol generating substrate to the atomization surface, and the heating body 22 is used for heating the aerosol generating substrate on the atomization surface to generate aerosol.
[0080] Specifically, the spring piece 31 is in interference fit with the heating body 22 to enable stable contact between the spring piece 31 and the heating body 22. The spring piece 31 has good electrical conductivity, the conductive piece 4 can transmit electrical energy to the heating body 22 through the spring piece 31, and the transmission process has good stability. The heating body 22 can heat the aerosol generating substrate to generate aerosol in the state of being electrified, thereby ensuring the operation reliability of the aerosol generating device 100.
[0081] The at least part of the heating body 22 arranged on the surface of the base body 21 means that part of the heating body 22 can be arranged on the surface of the base body 21, or the entire heating body 22 can be arranged on the surface of the base body 21.
[0082] The base body 21 can be a porous structure. The porous structure refers to a structure having a plurality of holes communicating with each other and with the outer surface of the base body 21. The holes in the porous structure are convenient for temporarily storing the liquid aerosol generating substrate and also for the liquid aerosol generating substrate to flow through. The holes can have a capillary effect, and the capillary force of the holes guides the aerosol generating substrate to the atomization surface.
[0083] The holes of the porous structure can be arranged in disorder, which means that the holes are randomly generated without rules.
[0084] The base body 21 can be made of ceramic material. Ceramic material has the characteristics of good thermal conductivity uniformity, etc. For example, the base body 21 can be made of porous ceramic material. The porous ceramic material can be generated by components such as aggregate, binder, pore-forming agent, etc. and high-temperature sintering.
[0085] The heating body 22 can be a heating film, that is, the aerosol generating device 100 generates aerosol by using the resistance heating method.
[0086] In some embodiments, please refer to Figure 4 and Figure 5 The protrusion 311 abuts against the heating body 22, so that the connection stability of the spring sheet 31 and the heating body 22 can be further improved, so that the electric energy will not be interrupted during transmission, and the operation reliability of the aerosol generating device 100 is ensured.
[0087] In some embodiments, please refer to Figure 8 and Figure 9 The conductive member 4 and the spring sheet 31 jointly define a limiting space 3a, the spring sheet 31 and the conductive member 4 abut against the two ends of the atomization core 2 opposite in the thickness direction respectively, and at least part of the atomization core 2 is located in the limiting space 3a. That is, the conductive member 4 is in contact with the atomization core 2, and the conductive member 4 can directly transmit electric energy to the atomization core 2. In this way, on the one hand, the conductive member 4 and the spring sheet 31 jointly limit the movement of the atomization core 2 in the thickness direction, and the conductive member 4 simultaneously plays the roles of electric conduction and limiting, and on the basis of ensuring the stability of the atomization core 2, the number of fixing structures such as the spring sheet 31 can be reduced, and the cost is reduced. On the other hand, the conductive member 4 and the spring sheet 31 are arranged in the thickness direction, the conductive member 4 and the spring sheet 31 do not contact, and the electric energy will not be transmitted to the spring sheet 31, which can prevent short circuit and cause the aerosol generating device 100 to be burned out.
[0088] In some embodiments, please refer to Figure 8 and Figure 9 The fixing bracket 3 is two, the two fixing brackets 3 are arranged in the thickness direction, and the conductive member 4 is located between the two fixing brackets 3 to define two limiting spaces 3a, and at least one atomization core 2 is arranged in each limiting space 3a.
[0089] For example, please refer toFigure 8 and Figure 9 The conductive piece 4 and the two fixing supports 3 are arranged in the thickness direction, and the elastic sheets 31 of the conductive piece 4 and the two fixing supports 3 define two limiting spaces 3a arranged in the thickness direction, and one atomization core 2 is arranged in each limiting space 3a. In this way, on the one hand, the at least two atomization cores 2 can be fixed at the same time through the cooperation of the conductive piece 4 and the fixing supports 3, and the conductive piece 4, the fixing supports 3 and the atomization cores 2 are compact in structure and good in stability. On the other hand, the contact area with the buffer structure 11 can be increased by increasing the number of atomization cores 2, thereby improving the atomization efficiency. On the other hand, the conductive piece 4 can simultaneously fix the at least two atomization cores 2, thereby reducing the number of parts required to fix each atomization core 2 and reducing the assembly difficulty.
[0090] For example, the atomization core 2 in each limiting space 3a is two, and the two atomization cores 2 are arranged side by side in the first direction.
[0091] In an embodiment, referring to Figure 7 The two atomization cores 2 abut against the buffer structure 11 away from the conductive piece 4, so that the two atomization cores 2 can heat the aerosol generating substrate and atomize into aerosol at the same time during use of the aerosol generating device 100, thereby improving the atomization efficiency and enabling the user to inhale aerosol with better taste and richness, thereby improving the user experience.
[0092] In some embodiments, referring to Figure 9 The conductive piece 4 abuts against the heating body 22. Specifically, the conductive piece 4 is in interference fit with the heating body 22 to enable stable contact between the conductive piece 4 and the heating body 22, thereby maintaining good stability during power transmission and ensuring the operation reliability of the aerosol generating device 100.
[0093] In some embodiments, referring to Figure 8 and Figure 9 The aerosol generating device 100 comprises an insulating piece 5, and the atomization core 2 is supported above the insulating piece 5.
[0094] The insulating piece 5 plays an insulating protection role, which can prevent the current in the atomization core 2 from being transmitted to the surrounding environment and prevent short circuit and the like. The insulating piece 5 also plays a supporting role for the atomization core 2, and the atomization core 2 can be placed on the supporting surface of the insulating piece 5 during assembly, thereby simplifying the assembly and reducing the installation difficulty.
[0095] For example, referring to Figure 9, two atomization cores 2 are respectively supported on two support surfaces of the insulating piece 5, and the two support surfaces are flush. That is, the two atomization cores 2 have the same height, so that the two atomization cores 2 can be more stably supported above the insulating piece 5, and the operation reliability of the aerosol generating device 100 is ensured.
[0096] It can be understood that the insulating piece 5 is prepared from an insulating material with good high-temperature resistance to meet the high-temperature and insulating operation environment. For example, the insulating piece 5 can be prepared from a plastic material.
[0097] In some embodiments, referring to Figure 9 , the fixed support 3 is supported on the top side of the insulating piece 5. In this way, the insulating piece 5 also supports the fixed support 3, and the components required to support the fixed support 3 can be omitted, thereby reducing the cost.
[0098] In some embodiments, referring to Figure 8 , the insulating piece 5 includes two limiting columns 51, and the two limiting columns 51 respectively abut two ends of the atomization core 2 along the first direction. In this way, the two limiting columns 51 can limit the movement of the atomization core 2 along the first direction, so that the atomization core 2 can be further stably supported on the insulating piece 5.
[0099] In some embodiments, referring to Figure 8 , the fixed support 3 includes two stoppers 32, and each limiting column 51 abuts the corresponding stopper 32 on the side away from the atomization core 2. For example, referring to Figure 8 , the space between the conductive piece 4 and the two stoppers 32 is a limiting space 3a, and the two limiting columns 51 are located in the limiting space 3a. In this way, the limiting space 3a limits the limiting columns 51, preventing the limiting columns 51 from being bent and deformed, causing the atomization core 2 to deviate and displace, and further enhancing the stability of the atomization core 2.
[0100] In an embodiment, referring to Figure 8 and Figure 10 , the stopper 32 forms a limiting portion 321, and the limiting portion 321 extends into the limiting space 3a and abuts the side of the limiting column 51 away from the conductive piece 4. In this way, the limiting portion 321 can enhance the connection stability of the fixed support 3 and the insulating piece 5, preventing the limiting column 51 from being disengaged from the limiting space 3a, thereby better fixing the atomization core 2.
[0101] In some embodiments, referring to Figure 9 and Figure 10 , the fixed support 3 includes a bearing sheet 34, the bearing sheet 34 is located on the side of the atomization core 2 away from the conductive piece 4, the bearing sheet 34 forms an avoiding gap 34a, and the elastic sheet 31 is connected to the bearing sheet 34, and at least part of the elastic sheet 31 is located in the avoiding gap 34a.
[0102] In this embodiment, the conductive piece 4, the two stop pieces 32 and the carrier sheet 34 jointly define the limiting space 3a, the avoidance gap 34a is in communication with the limiting space 3a, and the partial buffer structure 11 is located on the side of the atomization core 2 away from the conductive piece 4. In this way, the aerosol generating substrate can enter the atomization core 2 through the avoidance gap 34a.
[0103] For example, please refer to Figure 9 , the conductive piece 4 and the elastic sheet 31 are respectively located at the two ends of the atomization core 2 along the thickness direction. In this way, the conductive piece 4 and the elastic sheet 31 respectively exert opposite forces on the atomization core 2 along the thickness direction, which can enhance the stability of the atomization core 2.
[0104] In one embodiment, please refer to Figure 9 and Figure 10 , the fixing support 3 includes at least two elastic sheets 31, and the at least two elastic sheets 31 are arranged at intervals around the circumferential direction of the avoidance gap 34a. The specific number of the elastic sheets 31 is not limited, which can be two, three or four, and the like. For example, please refer to Figure 9 and Figure 10 , the avoidance gap 34a is substantially rectangular, and the elastic sheet 31 is four, and the four elastic sheets 31 are respectively located at the four vertices of the avoidance gap 34a.
[0105] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 7 , the aerosol generating device 100 includes a housing assembly 6, the housing assembly 6 forms a suction channel 6a, the liquid storage assembly 1 forms an atomization channel 1b, the suction channel 6a is in communication with the atomization channel 1b, and the atomization channel 1b and the suction channel 6a are both used for conveying aerosol.
[0106] For example, the housing assembly 6 is formed with a containing cavity, the liquid storage assembly 1 is arranged in the containing cavity, the housing assembly 6 plays a protective and sealing role on the liquid storage assembly 1, and prevents the aerosol generating substrate from leaking out. The outer surface of the housing assembly 6 can be a smooth curved surface, which is aesthetically pleasing and also facilitates the user to hold the aerosol generating device 100.
[0107] Please refer to Figure 2 and Figure 7 , the buffer structure 11 forms the atomization channel 1b, and at least part of the atomization core 2 is located in the atomization channel 1b. In this way, the aerosol after being atomized by the atomization core 2 can smoothly flow through the atomization channel 1b and the suction channel 6a for the user to smoke.
[0108] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 7The housing assembly 6 comprises a suction nozzle 61, which forms a suction passage 6a through which a user can draw aerosol. The specific material of the suction nozzle 61 is not limited, and for example, the suction nozzle 61 can be made of plastic.
[0109] In some embodiments, referring to Figure 2 and Figure 11 The liquid storage assembly 1 comprises a liquid storage shell 12, which is formed with a liquid storage pipe 121, at least part of the liquid storage pipe 121 extends into the atomization passage 1b, the liquid storage pipe 121 communicates with the atomization passage 1b, and the circumferential surface of the liquid storage pipe 121 abuts against the wall surface of the atomization passage 1b. In this way, the liquid storage pipe 121 plays a supporting role on the atomization passage 1b, preventing the contraction of the buffer structure 11 after the aerosol generating substrate in the buffer structure 11 is reduced, causing the atomization passage 1b to be closed and affecting the flow of aerosol.
[0110] In some embodiments, referring to Figure 2 and Figure 7 The liquid storage assembly 1 comprises two sealing seats 13, which are arranged on both sides of the liquid storage shell 12 along the top-bottom direction, and the liquid storage shell 12 and the two sealing seats 13 together define a liquid storage cavity 1a. In this way, the sealing seat 13 plays a better sealing role, preventing the aerosol generating substrate from seeping out of the liquid storage cavity 1a.
[0111] The specific material of the sealing seat 13 is not limited, for example, it can be made of flexible material, such as silicone material.
[0112] In one embodiment, referring to Figure 2 and Figure 7 The conductive member 4 penetrates the sealing seat 13 on the bottom side. Specifically, the conductive member 4 is in interference fit with the sealing seat 13 on the bottom side. In this way, the sealing seat 13 not only can play a fixing role on the conductive member 4, reducing the parts required to fix the conductive member 4, but also can prevent the aerosol generating substrate from seeping out of the gap between the conductive member 4 and the sealing seat 13.
[0113] In one embodiment, the sealing seat 13 on the bottom side is formed with an air exchange passage, and the liquid storage cavity 1a communicates with the atmosphere through the air exchange passage.
[0114] It should be noted that the air pressure in the liquid storage cavity 1a is less than the atmospheric pressure, and the air pressure in the liquid storage cavity 1a is negative relative to the atmospheric pressure. That is to say, the air exchange passage is a one-way passage, so that the aerosol generating substrate in the liquid storage cavity 1a cannot overflow outward through the air exchange passage, and the external air can enter the liquid storage cavity 1a through the air exchange passage.
[0115] For example, during the user inhaling the aerosol, the aerosol generating substrate in the buffer structure 11 gradually decreases, the cavity volume gradually increases, the air pressure in the liquid storage cavity 1a gradually decreases, and the external air can enter the liquid storage cavity 1a through the air exchange channel to compensate the air pressure in the liquid storage cavity 1a, so as to maintain the air pressure stability of the liquid storage cavity 1a.
[0116] In some embodiments, referring to Figure 2 and Figure 7 The aerosol generating device 100 comprises an electric core assembly 7 arranged in the accommodating cavity, and the electrically conductive member 4 is electrically connected with the electric core assembly 7. The electric core assembly 7 refers to a device capable of storing electric energy, and the electric energy of the electric core assembly 7 can be transmitted to the atomization core 2 through the electrically conductive member 4. In this way, on the one hand, the electric core assembly 7 can ensure the endurance performance of the aerosol generating device 100, and the user can inhale the aerosol at any time, thereby improving the user experience. On the other hand, the shell assembly 6 can avoid the electric core assembly 7 from being touched by external structures, thereby providing better protection for the electric core assembly 7.
[0117] For example, the electric core assembly 7 comprises a secondary battery, which refers to a battery that can be activated by charging after discharging. In this way, the user can charge the secondary battery, so as to repeatedly use the electric core assembly 7 and reduce the cost.
