[0048] Figure 17 is Figure 13 a disassembled structural schematic diagram of the power supply device in Detailed implementation manners

[0049] For the convenience of understanding the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific implementation manners.

[0050] The electric heating smoke generating system product according to an embodiment of the present invention is described below by taking the flat cigarette type as an example in the following drawings; and its structural idea and use can be extended to other types of electric heating smoke generating system products, such as non-combustion baking heating electric heating smoke generating system products, etc. For a specific electric heating smoke generating system according to an embodiment, see Figures 2 to 3 as shown.

[0051] The system includes a power supply device 10 assembled by a detachable connection method and an aerosol generating device 20 for generating aerosol; wherein, Figure 2 is a schematic diagram after the power supply device 10 and the aerosol generating device 20 are assembled, Figure 3 is a schematic diagram of the disassembled state of the power supply device 10 and the aerosol generating device 20.

[0052] For the structure of the above power supply device 10, see Figure 4 as shown, on which a pair of conductive contacts 11 are provided; it can be seen from the figure that there are two conductive contacts 11, corresponding to the positive electrode and the negative electrode respectively, and serving as the positive and negative electrode connection points of the power supply device 10. And a battery body is installed inside the power supply device 10; based on the fact that this content is relatively common sense and is not easy to be marked inside in the figure, the battery body is not shown in the figure.

[0053] For the structure of the aerosol generating device 20, see Figure 5As shown, first, there is an atomizer 24 that realizes the smoking function and is used to generate the smoke for smokers to inhale. Among them, the atomizer 24 is used to receive the aerosol-forming substrate and heat it to generate the aerosol that can be inhaled by smokers. The aerosol-forming substrate can be a solid substrate or a liquid e-liquid substrate. The solid substrate is, for example, a volatile tobacco material that contains volatile tobacco flavor compounds and is released from the substrate when heated; the solid substrate can also include tobacco powders, granules, strips, flakes, etc. that can emit smoke after heating. The liquid e-liquid substrate is, for example, one that contains glycerol, propylene glycol, etc.

[0054] To cooperate with the realization of the basic function of the atomizer 24, the aerosol generating device 20 is provided with a pair of conductors 21 for corresponding conductive connection with the conductive contacts 11. In order for the above power supply device 10 and aerosol generating device 20 to smoothly adjust the conductive and non-conductive states, the power supply device 10 and the aerosol generating device 20 have two connection positions relative to each other, specifically the first connection position A and the second connection position B, as shown in Figure 2 and Figure 6 respectively; among them,

[0055] When in Figure 2 the first connection position A shown, the positions of the conductors 21 corresponding to the conductive connection of the conductive contacts 11 are staggered from each other, and they are in a non-conductive connection state;

[0056] While when in Figure 6 the second connection position B shown, the positions of the conductors 21 corresponding to the conductive connection of the conductive contacts 11 are aligned and in contact with each other, forming a conductive connection state;

[0057] And in the first connection position A and the second connection position B, the power supply device 10 and the aerosol generating device 20 both remain in a connected state and do not separate from each other.

[0058] To facilitate the transformation of the power supply device 10 and the aerosol generating device 20 of the embodiment between the two connection states, the power supply device 10 and the aerosol generating device 20 adopt a structure design of movable connection; specifically, in Figure 4 and Figure 5In the preferred embodiment shown, a sliding connection method is adopted. The power supply device 10 is in a longitudinally elongated shape and has a proximal end 110 and a distal end 220 opposite to each other in the length direction. A sliding groove 13 is provided along the length direction extending from the proximal end 110 to the distal end 120, and a sliding buckle 23 adapted to the sliding groove 13 is correspondingly provided on the aerosol generating device 20. By fitting and installing the sliding buckle 23 with the sliding groove 13, the power supply device 10 and the aerosol generating device 20 can slide relative to each other. Moreover, in detail, the aerosol generating device 20 is hooked to the power supply device 10 through a hooked portion 231 bent at the front end of the sliding buckle 23, and the power supply device 10 and the aerosol generating device 20 remain connected during sliding to prevent them from separating from each other.

[0059] In other embodiments of the above guiding structure of the sliding groove 13 / sliding buckle 23, their positions can be replaced with each other. Specifically, for example, the sliding groove 13 can be changed to be provided on the aerosol generating device 20, and the corresponding sliding buckle 23 is provided on the power supply device 10. In other embodiments, the guiding connection structure of the sliding groove 13 / sliding buckle 23 can also be replaced with other guiding connection structures such as a push rod, as long as it can ensure that the aerosol generating device 20 and the power supply device 10 can be provided with direction guidance when moving between the first connection position A and the second connection position B.

[0060] In this movable connection method, the above first connection position A and second connection position B are correspondingly arranged along the relative sliding direction, as Figure 2 and Figure 6 shown. Figure 6 The second connection position B is that the aerosol generating device 20 is Figure 2 obtained by sliding a certain stroke relative to the power supply device 10 along the length direction from the first connection position A.

[0061] It should be noted that in the above embodiments, based on the aesthetic design that the sizes of the aerosol generating device 20 and the power supply device 10 of the product are quite the same in the length direction, the aerosol generating device 20 and the power supply device 10 overlap in the length direction. However, in addition to the above preferred design, the length direction of the aerosol generating device 20 and the length direction of the power supply device 10 can also have a certain included angle with each other, so that the two present an X-shaped cross shape. Then the above sliding connection can be set.

[0062] Furthermore, in the above preferred embodiment, the sliding path between the aerosol generating device 20 and the power supply device 10 between the first connection position A and the second connection position B is a straight-line stroke along the length direction; while in other modified embodiments, the sliding path can also be designed to be arc-shaped / bent, etc., as long as it can ensure that the conductive connection state can be changed by sliding between the first connection position A and the second connection position B.

[0063] Meanwhile, in order to further facilitate the accurate positioning of both the aerosol generating device 20 and the power supply device 10 at the first connection position A and the second connection position B, a positioning structure is also designed in the structure; specifically, see Figure 4 and Figure 5 , a positioning hole 12 is provided on the power supply device 10, and a spring pin 22 that cooperates with the positioning hole 12 for positioning is provided on the aerosol generating device 20; further, as shown in Figure 4 , the positioning hole 12 includes two groups, namely the first group of positioning holes 121 for positioning the first connection position A and the second group of positioning holes 122 for positioning the second connection position B; when sliding at the first connection position A and the second connection position B respectively, the spring pin 22 can be respectively snapped into the corresponding positioning hole 12 under the elastic force to achieve positioning. Of course, based on the same positioning function, the above-mentioned positioning method of the cooperation between the positioning hole 12 and the spring pin 22 in the embodiment can be replaced by a positioning post / slot, a limiting structure, etc. that can guide the sliding position.

[0064] Based on the implementation of the structure and function of these details, for the aerosol generating device 20 in this embodiment, the details of its structure and assembly can be seen in the exploded view shown in Figure 7 , which includes a hollow outer shell 210, inside which a main substrate 220 and a middle cover 230 for assisting the assembly and fixing of the main substrate 220 are accommodated; among them, a sliding buckle 23 is provided on the outer shell 210, and a conductor 21 and a spring pin 22 are both provided on the main substrate 220 and penetrate through the corresponding assembly holes on the middle cover 230 and the outer shell 210 until part of them are exposed outside the surface of the outer shell 210, so as to be connected to the conductive contact 11 and the positioning hole 12 on the power supply device 10. In addition, the main core functional component, the atomizer 24, is also connected to the main substrate 220 and is conductively connected to the conductor 21.

[0065] Specifically, for the structure of the atomizer 24 and its assembly connection with the main substrate 220, in this embodiment, see Figure 7 and Figure 8 . In the figure, the atomizer 24 takes the product type that stores e-liquid and heats and atomizes it as an example, and includes a smoking body 241 that stores e-liquid and atomizes it, an aerosol mouthpiece rod 242 provided on the smoking body 241, and a mouthpiece cap 243 for covering the mouthpiece rod 242; compared with the existing flat atomizer products, the above atomizer 24 has more appropriate convenience in structure. The structure of the e-liquid atomizing type atomizer 24 can be seen in the sectional view shown in Figure 8 .

[0066] Figure 8Among them, the smoke-generating body 241 includes a hollow cylindrical outer casing 2410, and the outer casing 2410 has an upper end close to the mouthpiece cap 243 and a lower end far from the mouthpiece cap 243; and the lower end of the outer casing 2410 is open, and an end cap 2412 is provided at the open lower end.

[0067] A part of the mouthpiece rod 242 penetrates through the upper end of the outer casing 2410 from the outside to the inside of the outer casing 2410; the mouthpiece rod 242 is a hollow tubular structure, and the internal hollow is configured as a smoke channel 2421 for transporting the smoke aerosol; the space between the outer wall of the part of the mouthpiece rod 242 penetrating into the outer casing 2410 and the inner wall of the outer casing 2410 forms an oil storage cavity 2411 for storing the e-liquid.

[0068] An atomization assembly is further provided in the outer casing 2410 for sucking the e-liquid from the oil storage cavity 2411 and heating and atomizing it; specifically, the atomization assembly includes a porous body 2414 with micropores inside, usually made of materials such as microporous ceramics / foam metal. The porous body 2414 Figure 8 In the embodiment, it is designed in a columnar shape and is arranged at the lower end of the mouthpiece rod 242 along the coaxial direction with the mouthpiece rod 242. The porous body 2414 has an axially penetrating through-hole inside, and a heating element 2415 is arranged on the inner surface of the through-hole, and the through-hole is communicated with the smoke channel 2412 for transporting the smoke to the smoke channel 2412. The e-liquid in the oil storage cavity 2411 flows to the outer surface of the porous body 2414 in the direction of arrow R1 to be absorbed, and is conducted to the inner surface of the through-hole through the micropores inside the porous body 2414, heated and atomized by the heating element 2415 to generate the smoke aerosol for inhalation, and then transported to the smoke channel 2412.

[0069] In order to stably hold the atomization assembly and prevent the e-liquid in the oil storage cavity 2411 from leaking, a silica gel seat 2413 is further provided between the atomization assembly and the inner wall of the outer casing 2410, which not only facilitates the installation of the atomization assembly but also prevents the e-liquid from leaking from the gap.

[0070] A pair of electrode posts 2417 are provided on the end cap 2412, and both ends of the heating element 2415 are electrically connected to the electrode posts 2417 through conductive pins 2416 respectively, so as to supply power to the heating element 2415 to enable it to work normally.

[0071] An air inlet hole is also opened on the end cap 2412, and the air inlet hole is arranged opposite to the axial through-hole of the porous body 2414. When sucking the mouthpiece rod 242, a negative pressure is generated inside the outer casing 2410, then the external air enters the outer casing 2410 through the air inlet hole, and enters the smoke channel 2421 of the mouthpiece rod 242 in the direction of arrow R2 and carries the smoke aerosol generated inside the porous body 2414 until it is inhaled at the upper end of the mouthpiece rod 242; thus forming a complete smoke circulation path.

[0072] Based on the above structure assembly and control of the aerosol generating device 20, in addition to installing and fixing other components, the main substrate 220 is preferably configured to be used as a main circuit board, which can save the internal space of the housing 210 and integrate the functions of the circuit board into the main substrate 220. The conduction between the conductor 21 and the atomizer 24 can be connected through the conductive circuit printed on the main substrate 220. This design, on the one hand, has better convenience compared with the method of using additional conductive leads to achieve conduction when there is no circuit board function; on the other hand, the circuit board originally set in the power supply part of the original flat cigarette product can be transferred to the aerosol generating device 20, saving the structural space of the power supply part and the convenience of assembly.

[0073] At the same time, in this embodiment, for the convenience of conductive assembly and anti-mistrigger of further controlling the atomizer 24, refer to Figure 7 ; an installation seat 25 for assisting the assembly of the atomizer 24 and the main substrate 220 is further provided on the main substrate 220. The installation seat 25 has a groove structure ([ Figure 7 which can be directly seen) adapted to the lower end of the housing of the atomizer 24, so as to facilitate directly inserting the atomizer 24 into the installation seat 25 for fixation. At the same time, for the convenience of supplying power to the atomizer 24, a conductive pin 26 is further provided on the main substrate 220. The conductive pin 26 has a first connection end 261 opposite to the atomizer 24, and the first connection end 261 is located in the groove structure of the installation seat 25. When the atomizer 24 is plugged into the installation seat 25, the electrode post 2417 in the atomizer 24 contacts the conductive pin 26 for conduction. The second connection end of the conductive pin 26 opposite to the first connection end 261 is conductively connected to the conductor 21 directly or indirectly through a lead.

[0074] Furthermore, in order to avoid mistrigger when the atomizer 24 is in the second connection position B, an airflow sensor 27 is provided on the main substrate 220, from Figure 7 and Figure 8It can be seen that the airflow sensor 27 is arranged opposite to the air inlet hole on the end cap 2412 of the atomizer 24, and the distance from the air inlet hole is ensured to be in the smoke circulation path during the suction of the atomizer 24, so as to sense the airflow during smoking. At the same time, a switch circuit (not shown in the figure) is arranged between the conductor 21 and the electrode post 2417 of the atomizer 24. When the airflow sensor 27 detects the airflow circulation generated by the user sucking the mouthpiece rod 242 of the atomizer 24, the control switch circuit is turned on to supply power to the atomizer 24; when the airflow sensor 27 does not detect the airflow, the switch circuit is in the off state to prevent the atomizer 24 from being accidentally triggered. At the same time, it can be seen from the above that the airflow sensor 27 is only in the conductive state when it is in the second connection position B and is connected to the power supply device through the conductor 21. Compared with the existing classic flat cigarette in which the sensor is arranged on the circuit board of the power supply part in a normally open state with stable conductivity, it can better prevent accidental triggering and improve the service life of the sensor.

[0075] The above ways of sliding connection and positioning are preferred designs based on the shapes of the longitudinally elongated power supply device 10 and the aerosol generating device 20 adopted in the embodiment; in other types of shapes or products, the way of movable connection can be changed to rotational connection according to the shape of the product, as long as the connection positions with the above conductive and non-conductive states can be ensured.

[0076] Furthermore, in order to facilitate the smoking action of the product in the conductive state at the second connection position B, in the design, when the aerosol generating device 20 is at the second connection position B, the atomizer 24 is in a protruding state relative to the power supply device 10. For details, see Figure 6 As shown, the atomizer 24 on the aerosol generating device 20 is arranged at one end in the length direction of the aerosol generating device 20 and is arranged close to the proximal end 110 of the power supply device. When the aerosol generating device 20 is at the second connection position B, at least a part of the mouthpiece cap 243 of the atomizer 24 protrudes relative to the proximal end 110 of the power supply device 10. The protruding design is more convenient for the smoker to perform the sucking action on the mouthpiece cap 243. At the same time, it can also be seen that when the atomizer 24 is at the first connection position A, it is flush with the proximal end of the power supply device 10, which is convenient for beautiful and hygienic storage.

[0077] Adopting the above electric heating smoking system of the present invention, compared with the existing e-cigarette products, the power supply device and the aerosol generating device are movably connected to adjust the conductive / non-conductive state in the connected state, so as to ensure safety and eliminate the possibility of accidental triggering of the aerosol generating device 100.

[0078] From Figures 2 to 8As can be seen from the illustrated embodiments, the power supply device 10 and the aerosol generating device 20 adopt a sliding connection along the length direction of the power supply device 10; in other modified embodiments, similar movable connections can be correspondingly replaced. For example, the aerosol generating device 20 can be designed to be rotatably connected to the power supply device 10 along the joint surface, and the aerosol generating device 20 and the power supply device 10 are rotated relative to each other by a certain angle within the joint surface to achieve conductive and non-conductive connections between the two; thereby preventing accidental triggering and facilitating inhalation.

[0079] Based on the above structure of the electrothermal smoking system of the present invention, another embodiment of the present invention further proposes another electrothermal smoking system product. Compared with the electrothermal smoking system of the previous embodiment, its structure is specifically shown in Figures 9 to 11 As shown, an additional functional component is added to the aerosol generating device 20a. Figure 9 and Figure 10 In, at the other end of the aerosol generating device 20a along the length direction opposite to the atomizer 24a, a charging component 30 is provided; in the figure, for the convenience of schematic illustration, a common USB charging component of this type of product is used as an example. The charging component 30 includes a USB interface 31, a cap 32, and a charging circuit (the technology is existing and not shown in the figure) located on the main substrate 220a. One end of the charging circuit is connected to the USB interface 31, and the other end is connected to the conductor 21; the charging component 30a is used to charge the power supply device 10a after being connected to the power supply device 10a through the conductor 21a on the main substrate 220a. And, the above charging circuit can be designed as a part of the circuit structure of the main substrate 220.

[0080] Further referring to Figure 12 As shown, the aerosol generating device 20a has a third connection position C opposite to the power supply device 10a, and another set of conductive contacts 112a is correspondingly provided on the power supply device 10a for connecting to the conductor 21a at the third connection position C for use in the charging state.

[0081] Of course, based on the fact that the charging state and the discharging state of the conventional power supply device 10a are not carried out simultaneously, in this embodiment, the circuit design on the main substrate 220a can be adjusted so that when at the second connection position B, the conductor 21b and the charging component 30 are in an open circuit state; and when in the third connection position C for the charging state, the conductor 21a and the atomizer 24a are in an open circuit state. On the one hand, it prevents simultaneous charging and discharging, and on the other hand, it can also make the atomizer 24a conduct electricity and work only at the second connection position B, reducing the possibility of accidental triggering and so on.

[0082] Meanwhile, based on the method of using a sliding connection to switch to different positions during implementation, in this embodiment, the third connection position C is also set along the sliding direction of the power supply device 10a and the aerosol generating device 20a. And preferably, the first connection position A is located between the second connection position B and the third connection position C in the sliding direction. Then, in this preferred implementation, the first connection position A is set as the initial reference position without conductive connection. After sliding in opposite directions respectively, the second connection position B and the third connection position C are obtained. Also, corresponding to the way that the atomizer 24a protrudes relative to the proximal end 110a during suction, the charging assembly 30 is arranged at the other end in the length direction opposite to the atomizer 24a, opposite to the distal end 120a of the power supply device 10a. And at the third connection position C, the USB charging interface 31 of the charging assembly 30 has a certain protruding length relative to the distal end 120a of the power supply device 10a, which is convenient for plugging the USB charging interface 31 into the adapted charging socket interface.

[0083] It should be noted that in the above Figures 9 to 12 embodiment, the aerosol generating device 20 / 20a is only provided with a group of conductors 21 / 20a, which are respectively in contact with the first conductive contact 111a and the second conductive contact 112a of the power supply device 10 / 10a at different positions for conduction. In other variant embodiments, the number of conductors 21a can be correspondingly increased to two groups. When corresponding to the second connection position B and the third connection position C, they are respectively in contact with the first conductive contact 111a and the second conductive contact 112a for conduction. Or, the number can be increased to more, and the atomizer 24a or the charging assembly 30 can be electrically connected to the power supply device 10a at the corresponding connection positions.

[0084] Based on the above embodiments, another variant embodiment of the present invention further proposes another electrothermal smoking system. The product structure of the electrothermal smoking system in this embodiment is shown in Figure 13 and Figure 14 as shown; in this embodiment, the structure of the power supply device 10b is the same as that of the previous embodiment, having:

[0085] a first conductive contact 111b that is connected to the conductor 21b of the aerosol generating device for conduction at the second connection position B, and a second conductive contact 112b that is connected to the conductor 21b of the aerosol generating device for conduction at the third connection position C;

[0086] and a first positioning hole 121b, a second positioning hole 122b, and a third positioning hole 123b for cooperating with the spring pins 22b of the aerosol generating device 20b for positioning at the first connection position A, the second connection position B, and the third connection position C;

[0087] and a sliding groove 13b that slides in the length direction for slidably connecting with the aerosol generating device 20b.

[0088] The difference in this embodiment lies in the aerosol generating device 20b, which has a first atomizer 24b and a second atomizer 40 respectively arranged at opposite ends in the length direction; wherein,

[0089] The first atomizer 24b is configured to be electrically connected to the power supply device 10b at the second connection position B to achieve suction, and the second atomizer 40 is configured to be electrically connected to the power supply device 10b at the third connection position C to achieve suction; and, based on the same concept as the above embodiment, when the first atomizer 24b corresponds to the second connection position B, it protrudes relative to the proximal end 110b of the power supply device 10b; when the second atomizer 40 corresponds to the third connection position C, it protrudes relative to the distal end 120b of the power supply device 10b, so as to facilitate the smoker to suck and draw.

[0090] In this embodiment, for the fixed assembly and working control of the atomizer, reference can be made to Figure 14 as shown. A first mounting seat 251b and a second mounting seat 252b are respectively arranged at both ends of the main substrate 220b along the relative sliding direction of the aerosol generating device 20b and the power supply device 10; the first atomizer 24b is fixedly assembled by plugging into the first mounting seat 251b, and the second atomizer 40 is fixedly assembled by plugging into the second mounting seat 252b; correspondingly, a first conductive pin 26b and a second conductive pin 28b for electrically connecting the conductor 21b to the first atomizer 24b and the second atomizer 40 respectively are also arranged on the main substrate 220b.

[0091] At the same time, a first airflow sensor 271b for controlling the operation of the first atomizer 24b and a second airflow sensor 272b for controlling the operation of the second atomizer 40 are arranged on the main substrate 220b. The first airflow sensor 271b and the second airflow sensor 272b are respectively arranged opposite to the air inlet holes on the end caps of the first atomizer 24b and the second atomizer 40, and are used to sense the airflow in the smoke circulation path when the first atomizer 24b and the second atomizer 40 respectively perform suction. And, corresponding to the concept of triggering the control of the respective atomizers by the airflow sensors, in practice, the switch circuit method described in the above embodiment can also be added to the circuit part of the main substrate 220, and the respective switch circuits are triggered by the airflow sensors to conduct electricity to supply power to the atomizers to prevent mis-triggering.

[0092] Further, in this embodiment, since the first air flow sensor 271b and the second air flow sensor 272b are located on a straight line in the length direction in the illustrated assembly, when the distance between them is not far enough, it is possible that the first air flow sensor 271b senses the air flow in the flue gas circulation path during the suction of the second atomizer 40, or conversely, the second air flow sensor 272b may sense the air flow in the flue gas circulation path during the suction of the first atomizer 24b, resulting in false triggering. Therefore, in this embodiment, air flow isolation components 50 are further provided on the main substrate 220b to isolate the air flow generated during the suction of the first atomizer 24b from the second air flow sensor 272b and the air flow generated during the suction of the second atomizer 40 from the first air flow sensor 271b, thereby preventing mutual false triggering. Specifically,

[0093] The air flow isolation component 50 includes an air flow isolation body 51. Specifically, the air flow isolation body 51 includes:

[0094] A first air flow isolation part 511 for isolating the air flow generated during the suction of the first atomizer 24b from the second air flow sensor 272b;

[0095] A second air flow isolation part 512 for isolating the air flow generated during the suction of the second atomizer 40 from the first air flow sensor 271b.

[0096] Meanwhile, further to promote the accurate sensing of the air flow sensor and the suction air flow of the corresponding atomizer, the air flow isolation component 50 is further added with a functional structure for air flow guiding. Specifically, the air flow guiding structure includes:

[0097] A first air flow guiding body 521 for guiding the air flow suctioned by the first atomizer 24b to be sensed by the first air flow sensor 271b;

[0098] A second air flow guiding body 522 for guiding the air flow suctioned by the second atomizer 40 to be sensed by the second air flow sensor 272.

[0099] Further refer to Figure 15, for the convenience of production and preparation, the first air flow isolation part 511 and the first air flow guide 521 are combined and prepared into an integral structure. Among them, in terms of the shape and design concept of the first air flow isolation part 511, on the one hand, it can block the air flow at the air inlet of the first atomizer 24b to prevent the gas from flowing to the second air flow sensor 272b; on the other hand, it forms a receiving cavity 5111, and the first air flow sensor 271b is received therein to prevent the first air flow sensor 271b from being interfered by the air flow of the second atomizer 40. The first air flow guide 521 has a first air flow guide channel 5211, one end of which is connected to the first air flow sensor 271b and the other end is connected to the air inlet of the first atomizer 271b, thus forming the function of air flow guidance.

[0100] The second air flow isolation part 512 and the second air flow guide 522 are prepared in the same integrated manner as Figure 14 described above and will not be described repeatedly.

[0101] In another embodiment, the air flow isolation between the two atomizers is carried out by Figure 16 another air flow isolation component 60 described in the embodiment. Specifically, it includes:

[0102] An air flow isolation plate 61, which can be seen from Figure 16 is arranged relatively in the middle along the first atomizer 24c and the second atomizer 40c to isolate the air flow generated by each atomizer at this position; and the first air flow sensor 271c is arranged between the first atomizer 24c and the air flow isolation plate 61, and the second air flow sensor is arranged between the second atomizer 40c and the air flow isolation plate 61.

[0103] Further referring to Figure 16 , the first air flow sensor 271c is located on the smoke circulation path Q1 during the suction of the first atomizer 24c to sense its suction action; and the second air flow sensor 272b is located on the smoke circulation path Q2 during the suction of the second atomizer 40c to sense its suction action; and since the air flow isolation plate 61 separates the smoke circulation paths Q1 and Q2 from each other, the mutual interference of the air flow is isolated. Based on the design concept, this air flow isolation plate 61 is simultaneously integrated with the functions of the two components of the first air flow isolation part 511 and the second air flow isolation part 512 in the previous embodiment.

[0104] Furthermore, in this embodiment, the first air flow guide 621 and the second air flow guide 622 are separately arranged from the air flow isolation plate 61. Its structure is the same as Figure 14 and Figure 15 described above and will not be elaborated.

[0105] It should be noted that the shapes and structures of the components in the above airflow isolation components 50 / 60 can be correspondingly changed and adjusted in combination with the structure of the main substrate 220b and the spatial arrangement of the components thereon in other different implementation scenarios. There is no need to limit to a specific shape, as long as it can satisfy the mutual airflow isolation to prevent the above-mentioned interference situations from occurring.

[0106] Furthermore, both ends of the aerosol generating device 20b with the above structure are designed as atomizers, and a charging module cannot be added. To ensure the charging function of the power supply device 10b during product use, refer to Figure 17 As shown, a charging component 30b is correspondingly provided on the power supply device 10. In Figure 17 , the conventional structures such as the housing of the power supply device 10b and the battery body (not shown) are not described in detail in this case. The charging component 30b includes a charging interface 31b, a charging circuit board 32b, and electrode connection pins 33b; among them, the charging interface 31b is used to adapt to the charging wire interface of the charger, the charging circuit board 32b realizes power conversion, and the electrode connection pins 33b are used for electrode connection of the battery body; the overall combination realizes the charging function of the power supply device 10b.

[0107] In the above dual-atomizer structure, based on similar usage scenarios, the first atomizer 24b and the second atomizer 40 can be extended or replaced from the type of heating e-liquid to the type of heating tobacco / volatile substances to produce smoke, and they can have different e-liquid flavors from each other to meet the more diverse smoking experiences of e-cigarette users. During use, after corresponding conduction through the conductor 21b and the conductive contacts 111b / 112b, they are powered by the power supply device 10b to heat and produce smoke.

[0108] It should be noted that the description and drawings of the present invention give preferred embodiments of the present invention, but are not limited to the embodiments described in this specification. Further, for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
