To make the purpose, the technical scheme and the advantages of the present disclosure more apparent, a clear and complete description is provided to the technical scheme in the embodiment of the present disclosure in conjunction with the drawings in the embodiment of the present disclosure. Obviously, the embodiments described hereinafter are simply part embodiments of the present disclosure, but all the embodiments. It should be understood that specific embodiments described hereinafter are merely to illustrate the present disclosure, but to limit the present disclosure. All other embodiments obtained by the ordinary skill in the art based on the embodiments in the present disclosure without creative work are intended to be included in the scope of protection of the present disclosure.

When one element is described as "connected to" another element, it may be directly connected to the other element, or there might be one or more intermediate elements between them. Terms "vertical", "horizontal", "left", "right" and similar expressions used in this description are merely for illustration.
In addition, technical features involved in each embodiment of the present disclosure described below can be combined mutually if no conflict is incurred.
An electric heating smoking system product according to one embodiment of the present disclosure is illustrated by taking a tabular electronic cigarette as shown in the drawings for example. The structure thought and usage can be expanded to other types of electric heating smoking system products, such as non-combustion electric heating smoking system products, etc. Specifically, an electric heating smoking system product in one embodiment can refer to what shown in FIG. 2 to FIG. 3.
The system includes a power source apparatus 10 and an aerosol generating apparatus 20 configured for generating an aerosol, which are assembled through a detachable manner. FIG. 2 is a diagram of a power source apparatus 10 and an aerosol generating apparatus 20 after assembly. FIG. 3 is a diagram of a power source apparatus 10 and an aerosol generating apparatus 20 after disassembly.
The above power source apparatus 10 can refer to FIG. 4 in terms of structure, on which a pair of conductive contacts 11 are disposed. From the figure, there are two conductive contacts 11, which correspond to a positive electrode and a negative electrode respectively and act as positive and negative electrode connection points of the power source apparatus 10 respectively. A battery main body is installed inside the power source apparatus 10. Since the battery is a common sense and is disposed inside the power source apparatus 10, not easy to view, the battery main body is not shown in the figure.
The aerosol generating apparatus 20 can refer to FIG. 5 in terms of structure, including an atomizer 24 which realizes a smoking function. The atomizer is configured for generating an aerosol for a user to inhale. The atomizer 24 accommodates an aerosol forming substrate and heats it to generate an aerosol that can be inhaled by a smoker. The aerosol forming substrate may be a solid substrate or a tobacco liquid substrate. The solid substrate, for example, is a volatile tobacco material, which includes volatile tobacco flavor compounds that are released out from the substrate when heated. The solid substrate may also include tobacco powder, particles, straps, slices and the like that can generate smoke when heated. The tobacco liquid substrate, for example, contains glycerin, Propylene Glycol, etc.
In order to implement the basic function of the atomizer 24, the aerosol generating apparatus 20 is provided with a pair of electric conductors21 for conductive connection to the conductive contacts 11.In order that the power source apparatus 10 and the aerosol generating apparatus 20 can adjust conductive and non-conductive states there-between smoothly, the power source apparatus 10 and the aerosol generating apparatus 20 include two connection positions relatively, namely a first connection position A and a second connection position B, as shown in FIG. 2 and FIG. 6 respectively; wherein

when at the first connection position A shown in FIG. 2, the conductive contacts 11 and the electric conductors21 for conductive connection are staggered with each other, to form a non-conductive connection state.
when at the second connection position B shown in FIG. 6, the conductive contacts 11 and the electric conductors21 for conductive connection are aligned and in contact, to form a conductive connection state;
moreover, the power source apparatus 10 and the aerosol generating apparatus 20 keep a connected state at both the first connection position A and the second connection position B, rather than a disengaged state.

In order that the power source apparatus 10 and the aerosol generating apparatus 20 in the present embodiment can switch between the two connection states, a structure of moveable connection is adopted between the power source apparatus 10 and the aerosol generating apparatus 20.In particular, preferred embodiments shown in FIG. 4 and FIG. 5 adopt a sliding connection manner. The power source apparatus 10 is elongated, which has a proximal end 110 and a distal end 120 opposite to one another along the length direction. A sliding groove 13 is defined along a length direction extended from the proximal end 110 towards the distal end 120, and correspondingly a sliding buckle 23 adapted to the sliding groove 13 is disposed on the aerosol generating apparatus 20. Through the adapted installation between the sliding buckle 23 and the sliding groove 13, the power source apparatus 10 and aerosol generating apparatus 20 can slide relative to one another. Furthermore, from details, the aerosol generating apparatus 20 keeps a hooked connection to the power source apparatus 10 through a bent hook buckle part 231 disposed on the front end of the sliding buckle 23; when sliding, the power source apparatus 10 and the aerosol generating apparatus 20 keep a connected state, preventing disengagement from each other.
Guide structures of the above sliding groove 13/sliding buckle 23may change positions with one another in other embodiments, for example, the sliding groove 13 is changed to be defined on the aerosol generating apparatus 20 and the corresponding sliding buckle 23 is disposed on the power source apparatus 10. In other embodiments, the guide connection structure of the sliding groove 13/sliding buckle 23 may be replaced with other guide connection structures such as push rod, as long as a direction guide can be provided when the aerosol generating apparatus 20 and the power source apparatus 10 move between the first connection position A and the second connection position B.
In this moveable connection approach, the first connection position A and the second connection position B are disposed along the relative sliding direction, as shown in FIG. 2 and FIG. 6. The second connection position B shown in FIG. 6 is obtained after the aerosol generating apparatus 20 slides relative to the power source apparatus 10for some distance along the length direction from the first connection position A shown in FIG. 2.
It is to be noted that, based on the aesthetic design in which the aerosol generating apparatus 20 and the power source apparatus 10 have a same size along the length direction, the aerosol generating apparatus 20 and the power source apparatus 10 are overlapped in the length direction in the above embodiments. However, beyond the above preferred design, an included angle may be formed between the length direction of the aerosol generating apparatus 20 and the length direction of the power source apparatus 10, so that the aerosol generating apparatus 20 and the power source apparatus 10 present in an X shape. Then, the above sliding connection is disposed.
Further, in the above preferred embodiments, the sliding path of the aerosol generating apparatus 20 and the power source apparatus 10 between the first connection position A and the second connection position B is a straight line travel along the length direction. However, in other transformative embodiments, the sliding path may be changed to a curve/bent shape and the like, as long as the conductive connection state can be changed through sliding between the first connection position A and the second connection position B.
Meanwhile, for the ease of correctly positioning the aerosol generating apparatus 20 and the power source apparatus 10 at the first connection position A and the second connection position B, a positioning mechanism is further provided on the structure. Referring to FIG. 4 and FIG. 5, a positioning hole 12 is defined on the power source apparatus 10, and a spring pin 22 fitting with the positioning hole 12 is disposed on the aerosol generating apparatus 20; further, as shown in FIG. 4, two groups of positioning holes 12 are defined, namely, a first group of positioning holes 12 configured for positioning the first connection position A and a second group of positioning holes 12 configured for positioning the second connection position B; when sliding to the first connection position A and the second connection position B respectively, the spring pin 22 can be clamped into the corresponding positioning hole 12respectively under the action of elastic force to realize positioning. Of course, based on the same positioning function, the above fit positioning manner between the positioning hole 12 and the spring pin 22adopted in the present embodiment may be replaced with a positioning pin/groove, a limit structure, etc., only if the sliding position can be guided.
Based on the detailed structure and function implementation, the detailed structure and the assembling of the aerosol generating apparatus 20 in the present embodiment can refer to the exploded view of FIG. 7. The aerosol generating apparatus 20 includes a hollow shell 210, inside which are accommodated an installation mainboard 220 and an intermediate cover 230 configured for assisting in assembling and fixing of the mainboard 220, wherein the sliding buckle 23 is disposed on the shell 210,the conductor 21 and the spring pin 22 are both disposed on the mainboard 220 and penetrate through corresponding mounting holes on the intermediate cover 230 and the shell 210 until partially exposed out of the surface of the shell 210,so as to be able to connected to the conductive contact 11 and the positioning hole 12 on the power source apparatus 10. In addition, the atomizer 24, the key function member, is also connected to the mainboard 220 and is in connected conduction with the conductor 21.
In particular, in the present embodiment, the structure of the atomizer 24 and the assembly connection between the atomizer 24 and the mainboard 220 can refer to FIG. 7 and FIG. 8. In the figures, the atomizer 24 takes a product type which stores, heats and atomizes a tobacco liquid as an example. The atomizer 24 includes a smoking main body 241 which stores and atomizes a tobacco liquid, an aerosol mouthpiece rod 242 disposed on the smoking main body 241, and a first mouthpiece cap 243 covering on the mouthpiece rod 242, wherein the first mouthpiece cap 243 is provided for a user to inhale an aerosol. The above atomizer 24, compared with the atomizer products of existing tabular electronic cigarettes, has better convenience in structure. The structure of the atomizer 24 of the tobacco liquid atomization type can refer to the sectional view shown in FIG. 8.
In FIG. 8, the smoking main body 241 includes a hollow cylindrical shell 2410, wherein the shell 2410 includes an upper end close to the first mouthpiece cap 243 and a lower end away from the first mouthpiece cap 243; the lower end of the shell 2410 is open, and the open lower end is provided with an end cover 2412.
One part of the mouthpiece rod 242 penetrates through the upper end of the shell 2410 to the interior of the shell 2140 from the outside; the mouthpiece rod 242 is a hollow tubular structure, of which the hollow interior is configured as a smoke channel 2421 for conveying a tobacco liquid aerosol; a liquid storage chamber 2411 for storing a tobacco liquid is formed between the outer wall of the mouthpiece rod 242 penetrating into the interior of the shell 2410 and the inner wall of the shell 2410.
The shell 2410 is internally provided with an atomization member for sucking in the tobacco liquid from the liquid storage chamber 2411 and then heating and atomizing the liquid; in particular, the atomization member includes a porous body 2414 with internal micropores, which generally adopts microporous ceramics/foaming metals and the like materials. In the embodiment of FIG. 8, the porous body 2414, designed to be cylindrical, is disposed on the lower end of the mouthpiece rod 242 coaxially with the mouthpiece rod 242. The porous body 2414 defines an axial through-hole internally, wherein an inner surface of the through hole is provided with a heating body 2415, and the through hole is communicated with the smoke channel2421 to convey smoke to the smoke channel 2421. The tobacco liquid in the liquid storage chamber 2411 flows along the direction of arrow R1 to the outer surface of the porous body 2414and is absorbed, then is conveyed to the inner surface of the through hole through the internal micropores of the porous body 2414, and finally is heated and atomized by the heating body 2415 to generate an inhalable tobacco liquid aerosol which is then conveyed to the smoke channel 2421.
In order to firmly hold the atomization member and prevent leakage of the tobacco liquid from the liquid storage chamber 2411, a silicon seat 2413 is disposed between the atomization member and the inner wall of the shell 2410, not only to ease the mounting of the atomization member, but also to prevent leakage of tobacco liquid through apertures.
The end cover 2412 is provided with a pair of electrode columns 2417, two ends of the heating body 2415 are conductively connected to the electrode columns 2417 through the conductive pins 2416 respectively, such that the heating body 2415 can be powered to normally work.
The end cover 2412 further defines an air inlet, wherein the air inlet is defined opposite to the axial through hole of the porous body 2414; when a user sucks on the mouthpiece rod 242, a negative pressure is generated inside the shell 2410, then external air gets inside the shell 2410 through the air inlet and carries the tobacco liquid aerosol generated inside the porous body 2414 to the smoke channel 2412 of the mouthpiece rod 242 along the direction of arrow R2, until conveyed to the upper end of the mouthpiece rod 242 to be inhaled. A complete smoke circulation path is formed.
On the basis of the structure assembly and control of the above aerosol generating apparatus 20, preferably the mainboard 220 is further configured as a main circuit board besides mounting and fixing other subassemblies, which can save the internal space of the shell 210; further, the function of the circuit board is integrated onto the mainboard 220, the electrical conduction between the conductor 21 and the atomizer 24 may be realized by the conducting circuit printed on the mainboard 220. This design on one hand has better convenience compared with the method in which additional leads are needed to realize conduction in the case of no circuit board, on the other hand transfers the circuit board originally disposed in the power source part in the tabular electronic cigarette product to the aerosol generating apparatus 20, thus saving the structure space of the power source part and facilitating the convenience of assembly.
Meanwhile, in the present embodiment, in order to further control the convenient conductive assembly and erroneously triggering of the atomizer 24, referring to FIG. 7, a mounting seat 25 is further disposed on the mainboard 220 to assist in the assembling between the atomizer 24 and the mainboard 220, wherein the mounting seat 25 includes a groove structure (as directly shown in FIG. 7) adapted to the lower end of the shell of the atomizer 24, so that the atomizer 24 can be directly inserted into the mounting seat 25 to fix. Meanwhile, for the ease of supplying power to the atomizer 24, the mainboard 220 is further provided with a conductive pin 26, wherein the conductive pin 26 includes a first connection end 261 opposite to the atomizer 24, the first connection end 261 is located inside the groove structure of the mounting seat 25; when the atomizer 24 is inserted and connected into the mounting seat 25, the electrode column 2417 inside the atomizer 24 contacts the conductive pin 26 and is electrically conducted. A 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.
In order to further avoid erroneously triggering when the atomizer 24 is at the second connection position B, the mainboard 220 is provided with an airflow sensor 27; as shown in FIG. 7 and FIG. 8, the airflow sensor 27 is disposed directly opposite to the air inlet on the end cover 2412 of the atomizer 24, and the distance between the airflow sensor 27 and the air inlet should ensure that the airflow sensor 27 is located on the smoke circulation path of sucking of the atomizer 24, so that the airflow sensor can sense the flow of air due to sucking. Meanwhile, a switch circuit (not shown in figure) is provided between the conductor 21 and the electrode column 2417 of the atomizer 24. If the airflow sensor 27 detects an air circulation which is generated when a user sucks on the mouthpiece rod 242 of the atomizer 24, the airflow sensor 27 controls the switch circuit to turn on so as to supply power to the atomizer 24; if the airflow sensor 27 does not detect an airflow, the switch circuit is off, preventing the atomizer 24 being erroneously triggered. Meanwhile, from the figure, the airflow sensor 27 is connected to the power source apparatus via the conductor 21 to keep in a conductive state only when at the second connection position B. Compared with the constant turn-on state of current classical tabular electronic cigarettes in which the sensor is disposed on the circuit board of the power source part to keep stable conductive, the present disclosure has a higher level of assurance in preventing erroneously triggering and improving the service life of the sensor.
The above sliding connection and positioning mode is an optimal design based on the shapes of the elongated power source apparatus 10 and the elongated aerosol generating apparatus 20; in other types of shapes or products, the mode of moveable connection may change to a rotating connection and the like according to the shape of the product, as long as it has the above connection positions of conductive and non-conductive states.
Further, in order to facilitate the smoking action on the product under the conductive state of the second connection position B, the atomizer 24 is designed to be protruded relative to the power source apparatus 10 when the aerosol generating apparatus 20 is at the second connection position B. Specifically referring to FIG. 6, the atomizer 24 on the aerosol generating apparatus 20 is disposed on one end of the aerosol generating apparatus 20 along the length direction, and is disposed close to the proximal end of the power source apparatus 110; when the aerosol generating apparatus 20 is at the second connection position B, at least one part of the first mouthpiece cap 243 of the atomizer 24 is protruded relative to the proximal end 110 of the power source apparatus 10; the protruded design is more convenient for a smoker to perform a sucking action on the first mouthpiece cap 243. Meanwhile, when the atomizer 24 is at the first connection position A, the atomizer 24 is level with the proximal end of the power source apparatus 10, which is good looking and is easy for sanitary storage.
With the present electric heating smoking system in the present disclosure, compared with current electronic cigarette products, the power source apparatus and the aerosol generating apparatus are movably connected to adjust the conductive/non-conductive state in a connected state, thereby ensuring safety and eliminating possibility of erroneously triggering the aerosol generating apparatus 100.
From embodiments of FIG. 2 to FIG. 8, the power source apparatus 10 and the aerosol generating apparatus 20 adopt a sliding connection along the length direction of the power source apparatus 10; however, in other transformative embodiments, the sliding connection may be replaced with a similar moveable connection. For example, the aerosol generating apparatus 20 and the power source apparatus 10 are designed with a rotating connection on the contact surface, the conductive and non-conductive connections between the aerosol generating apparatus 20 and the power source apparatus 10 are realized by rotating them for certain angle on the contact surface, so as to prevent erroneously triggering and facilitate inhaling.
Based on the structure of the electric heating smoking system in the present disclosure, another embodiment of the present disclosure further provides an electric heating smoking system product, as shown in FIG. 9 to FIG. 11, which adds an additional function member on the aerosol generating apparatus 20a compared with the electric heating smoking system in the above one embodiment. As shown in FIG. 9 and FIG. 10, another end of the aerosol generating apparatus 20a opposite to the atomizer 24a along the length direction is provided with a charging member 30; for convenient illustration, take a USB charging member commonly used by this type of products for example. The charging member 30 includes a USB interface 31, a cap 32, and a charging circuit (available technology, not shown in figure) disposed on the mainboard 220a, wherein one end of the charging circuit is connected to the USB interface 31 while the other end is connected to the conductor 21; the charging member 30a is configured for charging the power source apparatus 10a, after the conductor 21a on the mainboard 220a is connected to power source apparatus 10a. Moreover, the above charging circuit may be designed as one part of the circuit structure of the mainboard 220.
Further, referring to FIG. 12, the aerosol generating apparatus 20a includes a third connection position C opposite to the power source apparatus 10a, and correspondingly, another group of conductive contacts 112a is disposed on the power source apparatus 10a for connecting to the conductor 21a when at the third connection position C, to keep a charging state.
Of course, when a conventional power source apparatus 10a is used, the charging state and the discharging state do not occur simultaneously; therefore, in this kind of embodiments, the circuit design on the mainboard 220a may be adjusted, such that the conductor 21b and the charging member 30 keep a disconnected state when at the second connection position B, the conductor 21b and the atomizer 24a keep a disconnected state when at the third connection position C; on one hand, charging and discharging are prevented occurring simultaneously; on the other hand, the atomizer 24a can only be electrically conducted to work when at the second connection position B, which reduces the possibility of erroneously triggering.
Meanwhile, based on the fact that different positions are switched through a sliding connection manner during implementations, in the present embodiment the third connection position C is also disposed along the sliding direction of the power source apparatus 10a and the aerosol generating device 201, 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. In this preferred embodiment, the first connection position A is set as an initial reference position with no conductive connection, the second connection position B and the third connection position C are obtained by sliding along opposite directions respectively. In addition, corresponding to the way the atomizer 24a is protruded relative to the proximal end 110a when inhaling, the charging member 30 is disposed on another opposite end of the atomizer 24a along the length direction, opposite to the distal end 120a of the power source apparatus 10a; when at the third connection position C, the USB charging interface 31 of the charging member 30 is protruded for certain length relative to the distal end 120a of the power source apparatus 10a, for the ease of plugging the USB charging interface 31 into an adapted charging port.
It should be noted that, in embodiments of FIG. 9 to FIG. 12, the aerosol generating apparatus 20/20a is provided with one group of conductors 21/20a only, which are in contact conduction with the first conductive contact 111a and the second conductive contact 112a of the power source apparatus 10/10aat different positions respectively; in other transformative embodiments, the number of the conductors 21a may increase to two groups, which are in contact conduction with the first conductive contact 111a and the second conductive contact 112a at the second connection position B and the third connection position C respectively. Or, the number of the conductors 21a may increase to more than two groups, only if the atomizer 24a or the charging member 30 is electrically connected to the power source apparatus 10a at a corresponding connection position.
On the basis of the above embodiments, another transformative embodiment of the present disclosure further provides another electric heating smoking system; the electric heating smoking system product in the present embodiment can refer to FIG. 13 and FIG. 14 in terms of structure. In the present embodiment, the structure of the power source apparatus 10n is the same as that in the above embodiment, which includes:

a first conductive contact 111b in connected conduction with the conductor 21b of the aerosol generating device when at the second connection position B, and a second conductive contact 112b in connected conduction with the conductor 21b of the aerosol generating device when at the third connection position C;
a first positioning hole 121b, a second positioning hole 122b and a third positioning hole 123b fitting with the spring pin 22b of the aerosol generating apparatus 20b when at the first connection position A, the second connection position B and the third connection position C; and
a sliding groove 13b along the length direction, in sliding connection with the aerosol generating apparatus 20b.

The difference of the present embodiment lies in the aerosol generating apparatus 20b, two opposite ends of which along the length direction are provided with a first atomizer 24b and a second atomizer 40 respectively, wherein
the first atomizer 24b is configured to be electrically connected to the power source apparatus 10b to realize smoking when at the second connection position B, the second atomizer 40 is configured to be electrically connected to the power source apparatus 10b to realize smoking when at the third connection position C; moreover, based on the same thought as the above embodiment, the first atomizer 24b is protruded relative to the proximal end 110b of the power source apparatus 10b when at the second connection position B, the second atomizer 40 is protruded relative to the distal end 120b of the power source apparatus 10b when at the third connection position C, which is convenient for a smoker to smoke.
Specifically, the second atomizer 40 includes a smoking main body 41 which stores and atomizes a tobacco liquid, a second aerosol mouthpiece rod 42 disposed on the smoking main body 41, and a second mouthpiece cap 43 covering on the second mouthpiece rod 42, wherein the second mouthpiece cap 43 is provided for a user to inhale an aerosol. When the aerosol generating apparatus 20b is at the third connection position C, at least one part of the second mouthpiece cap 43 of the second atomizer 40 is protruded relative to the distal end 120b of the power source apparatus 10;the protruded design is more convenient for a smoker to perform a sucking action on the second mouthpiece cap 43. Meanwhile, when the second atomizer 40 is at the first connection position A, the atomizer 40 is level with the distal end 120b of the power source apparatus 10, which is good looking and is easy for sanitary storage.
In the present embodiment, the fixing and assembling and work control of the atomizer can refer to FIG. 14. The mainboard 220b is provided with a first mounting seat 251b and a second mounting seat 252b respectively at two ends along the relative sliding direction between the aerosol generating device 20b and the power source device 10; the first atomizer 24b is inserted into the first mounting seat 251b to be fixed and assembled, the second atomizer 40 is inserted into the second mounting seat 252b to be fixed and assembled; correspondingly, the mainboard 220b is further provided with a first conducive pin 26b and a second conductive pin 28b for connecting the conductor 21b to the first atomizer 24b and the second atomizer 40 respectively.
Meanwhile, the mainboard 220b is further provided with a first airflow sensor 271b for controlling the first atomizer 24b to work and a second airflow sensor 272b for controlling the second atomizer 40 to work respectively. The first airflow sensor 271b and the second airflow sensor 272b are disposed opposite to the air inlets on the end covers of the first atomizer 24b and the second atomizer 40 respectively, for sensing the airflows in respective smoke circulation paths when the first atomizer 24b and the second atomizer 40 are sucked respectively. It is to be noted that the corresponding smoke circulation path when the first atomizer 24 is sucked is called a first smoke circulation path, the corresponding smoke circulation path when the second atomizer 40 is sucked is called a second smoke circulation path. In addition, corresponding to the thought that the airflow sensors trigger and control the work of the respective atomizers, the circuit part of the switch circuit mode described in the above embodiment may be added on the mainboard 220 in the present embodiment, which triggers the conduction of the switch circuit through the respective airflow sensor so as to power the atomizer and prevent erroneously triggering.
Further, in the present embodiment, since the first airflow sensor 271b and the second airflow sensor 272b are assembled in a straight line along the length direction as shown in figure, when the distance between first airflow sensor 271b and the second airflow sensor 272b is not long enough, it is possible that the first airflow sensor 271b senses the flow of air in the smoke circulation path of sucking of the second atomizer 40, or instead the second airflow sensor 271b senses the flow of air in the smoke circulation path of sucking of the first atomizer 24b, thereby causing erroneously triggering. Therefore, during the implementation, the mainboard 220b is further provided with an airflow isolating member 50, which is configured for isolating the airflow generated when the first atomizer 24b is sucked from the second airflow sensor 272b, and isolating the airflow generated when the second atomizer 40 is sucked from the first airflow sensor 271b, thereby prevent mutual erroneous triggering. Specifically,

the airflow isolating member 50 includes an airflow isolating body 51, wherein the airflow isolating body 51 includes:
a first airflow isolating part 511, which is configured for isolating the airflow generated when the first atomizer 24b is sucked from the second airflow sensor 272b; and
a second airflow isolating part 512, which is configured for isolating the airflow generated when the second atomizer 40 is sucked from the first airflow sensor 271b.

Meanwhile, to further ensure the airflow sensor to correctly sense the airflow sucked by the corresponding atomizer, the airflow isolating member 50 is also provided with an airflow guide function structure. Specifically, the airflow guide function structure includes:

a first airflow guide body 521, which is configured for guiding the airflow sucked by the first atomizer to the first airflow sensor 271b to sense; and
a second airflow guide body 522, which is configured for guiding the airflow sucked by the second atomizer 40 to the second airflow sensor 272 to sense.

Further, referring to FIG. 15, for the ease of production and preparation, the first airflow isolating part 511 and the first airflow guide body 521 are combined and prepared as an integrated structure. The shape and design of the first airflow isolating part 511, on one hand, can shield the airflow in the air inlet of the first atomizer 24b and prevent the airflow flowing to the second airflow sensor 272b, and on the other hand, can form an accommodating chamber 5111, which accommodates the first airflow sensor 271b therein, preventing the first airflow sensor 271b being interfered by the airflow of the second atomizer 40. The first airflow guide body 521 includes a first airflow guide channel 5211, of which one end 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 guide function.
The second airflow isolating part 512 and the second airflow guide body 522 shown in FIG. 14 are prepared adopting the same integrated mode, and no further description is needed here.
In another embodiment, the airflow isolation between the two atomizers is realized by another airflow isolating member 60 described in the embodiment of FIG. 16. Specifically, the airflow isolating member 60 includes:
an airflow isolating board 61, which from FIG. 16 is disposed in the relative middle of the first atomizer 24c and the second atomizer 40c, to isolate the airflows generated by the respective atomizers; the first airflow sensor 271c is disposed between the first atomizer 24c and the airflow isolating board 61, the second airflow sensor is disposed between the second atomizer 40c and the airflow isolating board 61.
Further, referring to FIG. 16, the first airflow sensor 271c is located on the smoke circulation path Q1 of sucking of the first atomizer 24c, to sense the sucking action; while the second airflow sensor 272b is located on the smoke circulation path Q2 of sucking of the second atomizer 40c, to sense the sucking action; since the airflow isolating board 61 isolates the smoke circulation paths Q1 and Q2 from each other, mutual interference of airflows is prevented. Based on this design idea, the airflow isolating board 61 integrates functions of both the first airflow isolating part 511 and the second airflow isolating part 511 described in the above embodiment.
Further, in this embodiment, the first airflow guide body 621 and the second airflow guide body 622 are disposed separated from the airflow isolating board 61. The structures of the first airflow guide body 621 and the second airflow guide body 622 are the same as those in FIG. 14 and FIG. 15, and no further description is needed here.
It is to be noted that the shape and construction of each part in the above airflow isolating member 50/60 may be changed and adjusted accordingly in other different scenarios depending on the structure of the mainboard 220b and the arrangement of parts on the mainboard 220b, without limiting specific shapes, as long as mutual isolation of airflows can be met and the above airflow interference can be prevented.
Further, both ends of the aerosol generating apparatus 20b of the above structure are provided with atomizers, and no charging module can be added. To ensure the charging function for the power source apparatus 10b when the product is used, referring to FIG. 17, a charging member 30b is disposed on the power source apparatus 10 correspondingly. In FIG. 17, the shell of the power source apparatus 10, the battery main body (not shown) and other common structures are not described in detail in the present embodiment. The charging member 30b includes a charging interface 31b, a charging circuit board 32b and an electrode connection pin 33b, wherein the charging interface 31b is configured to be adapted to a charging line connector of a charger, the charging circuit board 32b realizes electric energy conversion, and the electrode connection pin 33b is configured for connection to electrodes of a battery main body; the whole realizes the charging function of the power source apparatus 10b.
In the above double-atomizer structure, based on a similar usage scenario, the first atomizer 24b and the second atomizer 40 may expand from the tobacco liquid heating type to the tobacco/volatile substance heating type or may be replaced with the tobacco/volatile substance heating type; moreover, they can use different flavors of tobacco liquids mutually, so as to meet more diversified smoking experiences for smokers of electronic cigarettes. When in use, both atomizers are powered by the power source apparatus 10b to generate an aerosol after the conductor 21b is connected to the conductive contact 111b/112b.

Any equivalent structures or equivalent process transformation made according to the description and the accompanying drawings of the present disclosure, or any equivalent structures or equivalent flow modifications applied in other relevant technical fields directly or indirectly are intended to be included in the patent protection scope of the present disclosure.
