[0049] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The electric heating smoking system product of one embodiment of the present invention is described in the following figure using the flat cigarette type as an example; however, its structural concept and use can be extended to other types of electric heating smoking system products, such as non-combustion baking heating electric heating smoking system products, etc. For details of the electric heating smoking system of one embodiment, see Figures 2 to 3 shown.

[0051] The system comprises a power supply device 10 and an aerosol generating device 20 for generating an aerosol, which are assembled in a detachable manner; wherein, Figure 2 is a schematic diagram of the power supply device 10 and the aerosol generating device 20 after being assembled, Figure 3 It is a schematic diagram of the power supply device 10 and the aerosol generating device 20 in a disassembled state.

[0052] The structure of the above power supply device 10 is shown in Figure 4 As shown, a pair of conductive contacts 11 are arranged thereon; it can be seen from the figure that the conductive contacts 11 include two, corresponding to the positive electrode and the negative electrode, respectively, serving as the positive and negative electrode connection points of the power supply device 10. A battery body is installed inside the power supply device 10; since this content is relatively common sense and it is not convenient to mark it in the figure because it is located inside, the battery body is not shown in the figure.

[0053] The structure of the aerosol generating device 20 is shown in FIG. Figure 5As shown, first, there is an atomizer 24 for realizing the smoking function, which is used to generate smoke for the smoker to inhale. Among them, the atomizer 24 is used to receive the aerosol-forming matrix and heat it to generate an aerosol for the smoker to inhale. The aerosol-forming matrix can be a solid matrix or a liquid smoke oil matrix. Solid matrices such as volatile tobacco materials contain volatile tobacco flavoring compounds that are released from the matrix when heated; solid matrices can also include smoke powders, particles, strips, sheets, etc. that can emit smoke after heating. Liquid smoke oil matrices, for example, contain glycerin, propylene glycol, etc.

[0054] In order to cooperate with the realization of the basic functions of the atomizer 24, the aerosol generating device 20 has a pair of conductors 21 for corresponding conductive connection with the conductive contacts 11. In order for the power supply device 10 and the 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 a first connection position A and a second connection position B, respectively. Figure 2 and Figure 6 As shown; among them,

[0055] In Figure 2 In the first connection position A shown, the conductive contacts 11 and the conductive bodies 21 connected to the conductive contacts 11 are staggered and in a non-conductive connection state;

[0056] and in Figure 6 In the second connection position B shown, the conductive contacts 11 and the conductive bodies 21 connected to each other are aligned and contacted with each other, forming a conductive connection state;

[0057] Furthermore, 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 connected rather than being disconnected from each other.

[0058] In order to facilitate the power supply device 10 and the aerosol generating device 20 of the embodiment to switch between the two connection states, the power supply device 10 and the aerosol generating device 20 are designed to be movably connected; specifically, Figure 4 and Figure 5The preferred embodiment shown adopts a sliding connection method. The power supply device 10 is in a longitudinal shape, and has a proximal end 110 and a distal end 220 opposite to each other along the length direction; a slide groove 13 is provided along the length direction extending from the proximal end 110 to the distal end 120, and a slide buckle 23 adapted to the slide groove 13 is provided on the aerosol generating device 20. By adapting and installing the slide buckle 23 to the slide groove 13, the power supply device 10 and the aerosol generating device 20 can slide relative to each other. In addition, in detail, the aerosol generating device 20 is connected to the power supply device 10 through the hook portion 231 bent at the front end of the slide buckle 23. When sliding, the power supply device 10 and the aerosol generating device 20 are both connected to prevent separation from each other.

[0059] In other implementations, the guide structures of the above slide groove 13 / slide buckle 23 can replace their respective positions, for example, the slide groove 13 is changed to be set on the aerosol generating device 20, and the corresponding slide buckle 23 is set on the power supply device 10. In other embodiments, the guide connection structure of the slide groove 13 / slide buckle 23 can also be replaced by other guide 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 provide direction guidance when moving between the first connection position A and the second connection position B.

[0060] In this active connection mode, the first connection position A and the second connection position B are set along the relative sliding direction. Figure 2 and Figure 6 As shown, Figure 6 The second connection position B is where the aerosol generating device 20 is connected to Figure 2 The first connection position A is obtained by sliding a certain distance relative to the power supply device 10 along the length direction.

[0061] It should be noted that in the above implementation, based on the aesthetic design that the product aerosol generating device 20 and the power supply device 10 have comparable dimensions along the length direction, the above aerosol generating device 20 and the power supply device 10 overlap in the length direction. However, in addition to the above preferred design, it is also possible to make the length direction of the aerosol generating device 20 and the length direction of the power supply device 10 have a certain angle with each other, so that the two appear in an X-shaped cross shape. Then the above sliding connection can also be set.

[0062] Further in the above preferred embodiment, the sliding path of 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; and in other variant embodiments, the sliding path change can also be designed to be an arc / bend shape, 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] At the same time, in order to facilitate accurate positioning of 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; see Figure 4 and Figure 5 The power supply device 10 is provided with a positioning hole 12, and the aerosol generating device 20 is provided with a spring pin 22 that cooperates with the positioning hole 12 for positioning; further, Figure 4 As shown, the positioning holes 12 include two groups, namely, a first group of positioning holes 121 for positioning the first connection position A, and a 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 pins 22 can be respectively snapped into the corresponding positioning holes 12 under the elastic force to achieve positioning. Of course, based on the same positioning function, the above positioning holes 12 and spring pins 22 used in the embodiment can be replaced by positioning columns / grooves, limit structures, etc. that can guide the sliding position.

[0064] Based on the implementation of these detailed structures and functions, the detailed structure and assembly of the aerosol generating device 20 in this embodiment can be seen in Figure 7 As shown in the exploded schematic diagram, it includes a hollow outer shell 210, which contains a main substrate 220 and a middle cover 230 for assisting the assembly and fixation of the main substrate 220; wherein, the slider 23 is arranged on the outer shell 210, and the conductor 21 and the spring pin 22 are arranged on the main substrate 220, and pass 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 with the conductive contact 11 and the positioning hole 12 on the power supply device 10. In addition, the main core functional component atomizer 24 is also connected to the main substrate 220, and is connected to the conductor 21 for electrical conduction.

[0065] Specifically, the structure of the atomizer 24 and the assembly connection with the main substrate 220 are shown in FIG. Figure 7 and Figure 8 As shown. The atomizer 24 in the figure takes the product type of storing smoke oil and heating and atomizing as an example, including a smoke-generating body 241 that stores smoke oil and atomizes it, an aerosol suction nozzle rod 242 arranged on the smoke-generating body 241, and a suction nozzle cap 243 for covering the suction nozzle rod 242; the above atomizer 24 has a more appropriate convenience in structure compared with the existing flat smoke atomizer products. The structure of the smoke oil atomizing type atomizer 24 can be seen in Figure 8 Cross-sectional view shown.

[0066] Figure 8In the figure, the smoking body 241 includes a hollow cylindrical outer shell 2410, the outer shell 2410 has an upper end close to the suction nozzle cap 243, and a lower end away from the suction nozzle cap 243; and the lower end of the outer shell 2410 is open, and the open lower end is provided with an end cover 2412.

[0067] A portion of the nozzle rod 242 passes through the upper end of the outer shell 2410 from the outside to the inside of the outer shell 2410; the nozzle rod 242 is a hollow tubular structure, and the internal hollow space is configured as a smoke channel 2421 for conveying tobacco oil aerosol; the nozzle rod 242 passes through the outer wall of the inner part of the outer shell 2410 and the space between the inner wall of the outer shell 2410 to form an oil storage chamber 2411 for storing tobacco oil.

[0068] The outer shell 2410 is also provided with an atomizing assembly for drawing the e-liquid from the oil storage chamber 2411 and heating and atomizing the e-liquid; the atomizing assembly specifically includes a porous body 2414 having micropores inside, which is usually made of materials such as microporous ceramics or foam metal. Figure 8 In the embodiment, it is of columnar design and is arranged at the lower end of the suction nozzle rod 242 in a coaxial manner with the suction nozzle rod 242. The porous body 2414 has an axial through hole inside, and a heating element 2415 is arranged on the inner surface of the through hole, and the through hole is connected with the smoke channel 2412 for conveying smoke to the smoke channel 2412. The smoke oil in the oil storage cavity 2411 flows to the outer surface of the porous body 2414 in the direction of arrow R1 and is absorbed, and is conducted to the inner surface of the through hole through the micropores inside the porous body 2414, and is heated and atomized by the heating element 2415 to generate a smoke oil aerosol for inhalation, which is conveyed to the smoke channel 2412.

[0069] In order to firmly maintain the atomizer assembly and prevent the oil in the oil storage chamber 2411 from leaking, a silicone seat 2413 is provided between the atomizer assembly and the inner wall of the outer shell 2410, which facilitates the installation of the atomizer assembly and prevents the oil from leaking from the gap.

[0070] A pair of electrode posts 2417 are disposed on the end cover 2412 , and both ends of the heating element 2415 are conductively connected to the electrode posts 2417 via conductive pins 2416 , thereby supplying power to the heating element 2415 and enabling it to work normally.

[0071] An air inlet hole is also provided on the end cover 2412, and the air inlet hole is arranged opposite to the axial through hole of the porous body 2414. When sucking the suction nozzle rod 242, negative pressure is generated inside the outer shell 2410, and external air enters the outer shell 2410 through the air inlet hole, and enters the smoke channel 2421 of the suction nozzle rod 242 in the direction of arrow R2 and carries the smoke oil aerosol generated in the porous body 2414, until it is transmitted to the upper end of the suction nozzle rod 242 to be sucked, thereby forming a complete smoke circulation path.

[0072] On the basis of the above structural assembly and control of the aerosol generating device 20, the main substrate 220 is preferably configured as a main circuit board in addition to being installed and fixed as other components, which can save the internal space of the outer shell 210, and integrate the function of the circuit board into the main substrate 220, and the electrical conduction between the conductor 21 and the atomizer 24 can be connected through the conductive line printed on the main substrate 220. This design, on the one hand, has better convenience than the method of requiring additional conductive leads to achieve conduction when there is no circuit board function; on the other hand, the circuit board 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, based on the convenience of further controlling the conductive assembly and false triggering of the atomizer 24, see Figure 7 A mounting base 25 for assisting the assembly of the atomizer 24 and the main substrate 220 is also provided on the main substrate 220, and the mounting base 25 has a groove structure adapted to the lower end of the outer shell of the atomizer 24 ( Figure 7 It can be seen directly), so that the atomizer 24 can be directly inserted into the mounting seat 25 for fixing. At the same time, in order to facilitate the power supply to the atomizer 24, a conductive pin 26 is also provided on the main substrate 220. The conductive pin 26 has a first connection end 261 opposite to the atomizer 24. The first connection end 261 is located in the groove structure of the mounting seat 25. When the atomizer 24 is plugged into the mounting seat 25, the electrode column 2417 in the atomizer 24 contacts the conductive pin 26 for electrical conduction. The second connection end of the conductive pin 26 opposite to the first connection end 261 is directly or indirectly connected to the conductor 21 through a lead wire.

[0074] To further prevent false triggering of the atomizer 24 when it is in the second connection position B, an airflow sensor 27 is provided on the main substrate 220. Figure 7 and Figure 8It can be seen that the position of the airflow sensor 27 is facing the air inlet on the end cover 2412 of the atomizer 24, and the distance between the airflow sensor 27 and the air inlet is ensured to be on the smoke circulation path when the atomizer 24 is sucked, so that the airflow flow during smoking can be sensed; at the same time, a switch circuit (not shown in the figure) is set between the conductor 21 and the electrode column 2417 of the atomizer 24. When the airflow sensor 27 detects that the user sucks the nozzle rod 242 of the atomizer 24 to generate airflow circulation, the switch circuit is controlled to be turned on to power the atomizer 24; and when the airflow sensor 27 does not detect the airflow, the switch circuit is disconnected to prevent the atomizer 24 from being triggered by mistake. At the same time, it can be seen from the above that the airflow sensor 27 is connected to the power supply device through the conductor 21 and is in a conductive state only when it is in the second connection position B. Compared with the normally open method of setting the sensor on the circuit board of the power supply part in the existing classic flat cigarette to stably conduct electricity, it can better prevent false triggering and increase the service life of the sensor.

[0075] The above sliding connection and positioning method is a preferred design based on the shape of the longitudinal power supply device 10 and the aerosol generating device 20 used in the embodiment; in other types of shapes or products, the movable connection method can be changed to a rotating connection according to the shape of the product, as long as the connection position with the above conductive and non-conductive states can be guaranteed.

[0076] In order to facilitate the smoking action of the product in the conductive state of the second connection position B, the aerosol generating device 20 is designed so that when the aerosol generating device 20 is in the second connection position B, the atomizer 24 is in a protruding state relative to the power supply device 10. Figure 6 As shown, the atomizer 24 on the aerosol generating device 20 is arranged at one end of the length direction of the aerosol generating device 20, and is arranged close to the proximal end 110 of the power supply device, and when the aerosol generating device 20 is in the second connection position B, at least a portion of the mouthpiece cap 243 of the atomizer 24 protrudes relative to the proximal end 110 of the power supply device 10, and the protruding design makes it easier for the smoker to suck on the mouthpiece cap 243. At the same time, it can also be seen that when the atomizer 24 is in the first connection position A, it is flush with the proximal end of the power supply device 10, which is convenient for aesthetic and hygienic storage.

[0077] Compared with existing electronic cigarette products, the above electric heating smoking system of the present invention uses a power supply device and an aerosol generating device through a movable connection to adjust the conductive / non-conductive state in the connected state, thereby ensuring safety and eliminating the possibility of mis-triggering of the aerosol generating device 100.

[0078] from Figures 2 to 8It can be seen from the embodiment shown that the power supply device 10 and the aerosol generating device 20 are connected by sliding along the length direction of the power supply device 10; in other variant embodiments, they can also be replaced with similar movable connections. For example, the aerosol generating device 20 and the power supply device 10 are designed to be connected by rotation along the joint surface, and the conductive and non-conductive connection between the aerosol generating device 20 and the power supply device 10 is achieved by rotating them at a certain angle within the joint surface; thereby preventing false triggering and facilitating inhalation.

[0079] Based on the above electric heating smoking system structure of the present invention, another embodiment of the present invention further provides another electric heating smoking system product. Compared with the electric heating smoking system of the above embodiment, its structure is specifically shown in Figures 9 to 11 As shown, additional functional components are added to the aerosol generating device 20a. Fig. 9 and Fig.10 In the figure, a charging assembly 30 is provided at the other end of the aerosol generating device 20a opposite to the atomizer 24a along the length direction; in order to facilitate schematic illustration, the USB charging assembly commonly used in this type of product is used as an example. The charging assembly 30 includes a USB interface 31, a cap 32, and a charging circuit located on the main substrate 220a (the technology is existing, not shown in the figure), 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 assembly 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. In addition, the above charging circuit can be designed as a part of the circuit structure of the main substrate 220.

[0080] See also Fig.12 As shown, the aerosol generating device 20a has a third connection position C relative to the power supply device 10a, and another set of conductive contacts 112a is correspondingly provided on the power supply device 10a for connecting with the conductor 21a at the third connection position C for use as a charging state.

[0081] Of course, based on the fact that the charging state and the discharging state are not performed simultaneously when the conventional power supply device 10a is used, in this embodiment, the circuit design on the main substrate 220a can be adjusted so that when in 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 charging, the conductor 21a and the atomizer 24a are in an open circuit state. On the one hand, this prevents charging and discharging from being performed simultaneously, and on the other hand, it also allows the atomizer 24a to conduct electricity only at the second connection position B, reducing the possibility of false triggering, etc.

[0082] At the same time, based on the use of sliding connection to switch different positions in the 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 it is preferred that 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 embodiment, the first connection position A is set as the initial reference position without conductive connection, and the second connection position B and the third connection position C are obtained after sliding in opposite directions respectively. In addition, based on the corresponding way that the atomizer 24a protrudes relative to the proximal end 110a during inhalation, the charging component 30 is set at the other end of the length direction opposite to the atomizer 24a, opposite to the distal end 120a of the power supply device 10a; and in the third connection position C, the USB charging interface 31 of the charging component 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 with the matching charging socket.

[0083] It should be noted that the above Figures 9 to 12 In the embodiment, the aerosol generating device 20 / 20a is provided with only one group of conductors 21 / 20a, which are in contact with the first conductive contact sheet 111a and the second conductive contact sheet 112a of the power supply device 10 / 10a at different positions for conducting electricity; in other variant embodiments, the number of conductors 21a can be increased to two groups, and they are in contact with the first conductive contact sheet 111a and the second conductive contact sheet 112a for conducting electricity at the second connection position B and the third connection position C. Alternatively, 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 position.

[0084] Based on the above embodiments, another variant embodiment of the present invention further proposes another electric heating smoking system. The product structure of the electric heating smoking system of this embodiment is shown in FIG. Fig.13 and Fig.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 piece 111b that is connected to the conductor 21b of the aerosol generating device for electrical conduction in the second connection position B, and a second conductive contact piece 112b that is connected to the conductor 21b of the aerosol generating device for electrical conduction in 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 pin 22b of the aerosol generating device 20b for positioning when in the first connection position A, the second connection position B, and the third connection position C;

[0087] And a slide groove 13b sliding along the length direction is used for sliding connection with the aerosol generating device 20b.

[0088] The different variation of this embodiment is that the aerosol generating device 20b has a first atomizer 24b and a second atomizer 40 respectively disposed at two opposite ends along the length direction; wherein,

[0089] The first atomizer 24b is configured to be electrically connected to the power supply device 10b in the second connection position B to achieve inhalation, and the second atomizer 40 is configured to be electrically connected to the power supply device 10b in the third connection position C to achieve inhalation; and, based on the same concept as the above embodiment, the first atomizer 24b protrudes relative to the proximal end 110b of the power supply device 10b in the second connection position B; the second atomizer 40 protrudes relative to the distal end 120b of the power supply device 10b in the third connection position C, thereby facilitating the smoker to suck and inhale.

[0090] In this embodiment, the fixed assembly and working control of the atomizer can be seen in Fig.14 The main substrate 220b is provided with a first mounting seat 251b and a second mounting seat 252b at both ends 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 with the first mounting seat 251b, and the second atomizer 40 is fixedly assembled by plugging with the second mounting seat 252b; the corresponding main substrate 220b is also provided with a first conductive needle 26b and a second conductive needle 28b for electrically connecting the conductor 21b with the first atomizer 24b and the second atomizer 40 respectively.

[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 provided 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 covers of the first atomizer 24b and the second atomizer 40, and are used to respectively sense the airflow in the smoke circulation path when the first atomizer 24b and the second atomizer 40 are each inhaled. In addition, corresponding to the intention of the airflow sensor to trigger the operation of each atomizer, the switch circuit method described in the above embodiment can also be added to the circuit part of the main substrate 220 in the implementation, and the conduction of each switch circuit is triggered by the airflow sensor to power the atomizer to prevent false triggering.

[0092] Further in this embodiment, since the first airflow sensor 271b and the second airflow sensor 272b are located in a straight line in the length direction in the assembly shown in the figure, when the distance between the two is not far enough, it is possible that the first airflow sensor 271b will sense the airflow in the smoke circulation path when the second atomizer 40 is inhaled, or conversely, the second airflow sensor 272b may sense the airflow in the smoke circulation path when the first atomizer 24b is inhaled, and a false triggering may occur; therefore, in this embodiment, airflow isolation components 50 are also provided on the main substrate 220b, which are used to isolate the airflow generated by the first atomizer 24b when inhaled from the second airflow sensor 272b, and to isolate the airflow generated by the second atomizer 40 when inhaled from the first airflow sensor 271b, so as to prevent mutual false triggering. Specifically,

[0093] The airflow isolation assembly 50 includes an airflow isolation body 51, and the airflow isolation body 51 specifically includes:

[0094] The first airflow isolation part 511 is used to isolate the airflow generated by the first atomizer 24b during suction from the second airflow sensor 272b;

[0095] The second airflow isolating portion 512 is used to isolate the airflow generated by the second atomizer 40 during suction from the first airflow sensor 271b.

[0096] At the same time, in order to further promote the accurate sensing of the airflow sensor and the corresponding atomizer suction airflow, the airflow isolation component 50 is also added with an airflow guiding functional structure. Specifically, the airflow guiding structure includes:

[0097] A first airflow guide 521, used for guiding the airflow sucked by the first atomizer 24b to be sensed by the first airflow sensor 271b;

[0098] The second airflow guide 522 is used to guide the airflow drawn by the second atomizer 40 to the second airflow sensor 272 for sensing.

[0099] See also Fig.15In order to facilitate production and preparation, the first airflow isolation part 511 and the first airflow guide body 521 are combined and prepared into an integrated structure. Among them, the shape and design concept of the first airflow isolation part 511 can, on the one hand, block the airflow at the air inlet of the first atomizer 24b and prevent the gas from flowing to the second airflow sensor 272b; on the other hand, it forms a accommodating cavity 5111, which accommodates the first airflow sensor 271b therein to prevent the first airflow sensor 271b from being disturbed by the airflow of the second atomizer 40. The first airflow guide body 521 has a first airflow guiding channel 5211, one end of which is connected to the first airflow sensor 271b and the other end is connected to the air inlet of the first atomizer 271b, thereby forming an airflow guiding function.

[0100] The second airflow isolating portion 512 and the second airflow guiding body 522 are Fig.14 The same integrated method is used for preparation and the description will not be repeated.

[0101] In another embodiment, the airflow isolation between the two atomizers is achieved by Fig.16 Another airflow isolation assembly 60 described in the embodiment is implemented. Specifically, it includes:

[0102] Airflow isolation plate 61, from Fig.16 It can be seen that the first atomizer 24c and the second atomizer 40c are arranged relatively in the middle, and the airflows generated by each atomizer are isolated at this position; the first airflow sensor 271c is arranged between the first atomizer 24c and the airflow isolation plate 61, and the second airflow sensor is arranged between the second atomizer 40c and the airflow isolation plate 61.

[0103] See also Fig.16 The first airflow sensor 271c is located on the smoke circulation path Q1 when the first atomizer 24c is inhaled, sensing its inhalation action; and the second airflow sensor 272b is located on the smoke circulation path Q2 when the second atomizer 40c is inhaled, sensing its inhalation action; and because the airflow isolation plate 61 isolates the smoke circulation paths Q1 and Q2 from each other, the mutual interference of the airflows is isolated. Based on the design idea, this airflow isolation plate 61 is integrated with the functions of the first airflow isolation part 511 and the second airflow isolation part 512 in the previous embodiment.

[0104] In this embodiment, the first airflow guide 621 and the second airflow guide 622 are separately provided from the airflow isolation plate 61. Fig.14 and Fig.15 The design is the same and will not be repeated here.

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

[0106] Furthermore, both ends of the aerosol generating device 20b of the above structure are designed as atomizers, and a charging module cannot be added. In order to ensure the charging function of the power supply device 10b when the product is used, see Fig.17 As shown, a charging assembly 30b is provided on the power supply device 10. Fig.17 In the present invention, the conventional structures of the power supply device 10b, such as the housing and the battery body (not shown), are not described in detail. The charging assembly 30b includes a charging interface 31b, a charging circuit board 32b, and an electrode connection pin 33b; wherein the charging interface 31b is used to adapt to the charging line interface of the charger, the charging circuit board 32b realizes power conversion, and the electrode connection pin 33b is used for connecting the electrodes 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 heated by tobacco oil, promoted or replaced by tobacco / volatile substances, and can have different tobacco oil flavors to meet the more diverse smoking experience of electronic cigarette users. When in use, the corresponding conductor 21b and the conductive contact 111b / 112b are connected, and the power supply device 10b supplies power to heat and emit smoke.

[0108] It should be noted that the preferred embodiments of the present invention are given in the specification and drawings of the present invention, but are not limited to the embodiments described in the specification. Furthermore, it is obvious to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present invention.
