In addition, technical features involved in each embodiment of the present invention described below can be combined mutually if no conflict is incurred.

An electric heating smoking system product according to one embodiment of the present invention 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>.

The system includes a power source apparatus <NUM> and an aerosol generating apparatus <NUM> configured for generating an aerosol, which are assembled through a detachable manner. <FIG> is a diagram of a power source apparatus <NUM> and an aerosol generating apparatus <NUM> after assembly. <FIG> is a diagram of a power source apparatus <NUM> and an aerosol generating apparatus <NUM> after disassembly.

The above power source apparatus <NUM> can refer to <FIG> in terms of structure, on which a pair of conductive contacts <NUM> are disposed. From the figure, there are two conductive contacts <NUM>, 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 <NUM> respectively. A battery main body is installed inside the power source apparatus <NUM>. Since the battery is a common sense and is disposed inside the power source apparatus <NUM>, not easy to view, the battery main body is not shown in the figure.

The aerosol generating apparatus <NUM> can refer to <FIG> in terms of structure, including an atomizer <NUM> which realizes a smoking function. The atomizer is configured for generating an aerosol for a user to inhale. The atomizer <NUM> 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 <NUM>, the aerosol generating apparatus <NUM> is provided with a pair of electric conductors21 for conductive connection to the conductive contacts <NUM>. In order that the power source apparatus <NUM> and the aerosol generating apparatus <NUM> can adjust conductive and non-conductive states there-between smoothly, the power source apparatus <NUM> and the aerosol generating apparatus <NUM> include two connection positions relatively, namely a first connection position A and a second connection position B, as shown in <FIG> and <FIG> respectively; wherein.

In order that the power source apparatus <NUM> and the aerosol generating apparatus <NUM> in the present embodiment can switch between the two connection states, a structure of moveable connection is adopted between the power source apparatus <NUM> and the aerosol generating apparatus <NUM>. In particular, preferred embodiments shown in <FIG> and <FIG> adopt a sliding connection manner. The power source apparatus <NUM> is elongated, which has a proximal end <NUM> and a distal end <NUM> opposite to one another along the length direction. A sliding groove <NUM> is defined along a length direction extended from the proximal end <NUM> towards the distal end <NUM>, and correspondingly a sliding buckle <NUM> adapted to the sliding groove <NUM> is disposed on the aerosol generating apparatus <NUM>. Through the adapted installation between the sliding buckle <NUM> and the sliding groove <NUM>, the power source apparatus <NUM> and aerosol generating apparatus <NUM> can slide relative to one another. Furthermore, from details, the aerosol generating apparatus <NUM> keeps a hooked connection to the power source apparatus <NUM> through a bent hook buckle part <NUM> disposed on the front end of the sliding buckle <NUM>; when sliding, the power source apparatus <NUM> and the aerosol generating apparatus <NUM> keep a connected state, preventing disengagement from each other.

Guide structures of the above sliding groove <NUM>/sliding buckle <NUM> may change positions with one another in other embodiments, for example, the sliding groove <NUM> is changed to be defined on the aerosol generating apparatus <NUM> and the corresponding sliding buckle <NUM> is disposed on the power source apparatus <NUM>. In other embodiments, the guide connection structure of the sliding groove <NUM>/sliding buckle <NUM> 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 <NUM> and the power source apparatus <NUM> 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> and <FIG>. The second connection position B shown in <FIG> is obtained after the aerosol generating apparatus <NUM> slides relative to the power source apparatus <NUM> for some distance along the length direction from the first connection position A shown in <FIG>.

It is to be noted that, based on the aesthetic design in which the aerosol generating apparatus <NUM> and the power source apparatus <NUM> have a same size along the length direction, the aerosol generating apparatus <NUM> and the power source apparatus <NUM> 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 <NUM> and the length direction of the power source apparatus <NUM>, so that the aerosol generating apparatus <NUM> and the power source apparatus <NUM> 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 <NUM> and the power source apparatus <NUM> 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 <NUM> and the power source apparatus <NUM> at the first connection position A and the second connection position B, a positioning mechanism is further provided on the structure. Referring to <FIG> and <FIG>, a positioning hole <NUM> is defined on the power source apparatus <NUM>, and a spring pin <NUM> fitting with the positioning hole <NUM> is disposed on the aerosol generating apparatus <NUM>; further, as shown in <FIG>, two groups of positioning holes <NUM> are defined, namely, a first group of positioning holes <NUM> configured for positioning the first connection position A and a second group of positioning holes <NUM> 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 <NUM> can be clamped into the corresponding positioning hole <NUM> respectively 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 <NUM> and the spring pin <NUM> adopted 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 <NUM> in the present embodiment can refer to the exploded view of <FIG>. The aerosol generating apparatus <NUM> includes a hollow shell <NUM>, inside which are accommodated an installation mainboard <NUM> and an intermediate cover <NUM> configured for assisting in assembling and fixing of the mainboard <NUM>, wherein the sliding buckle <NUM> is disposed on the shell <NUM>, the conductor <NUM> and the spring pin <NUM> are both disposed on the mainboard <NUM> and penetrate through corresponding mounting holes on the intermediate cover <NUM> and the shell <NUM> until partially exposed out of the surface of the shell <NUM>, so as to be able to connected to the conductive contact <NUM> and the positioning hole <NUM> on the power source apparatus <NUM>. In addition, the atomizer <NUM>, the key function member, is also connected to the mainboard <NUM> and is in connected conduction with the conductor <NUM>.

In particular, in the present embodiment, the structure of the atomizer <NUM> and the assembly connection between the atomizer <NUM> and the mainboard <NUM> can refer to <FIG> and <FIG>. In the figures, the atomizer <NUM> takes a product type which stores, heats and atomizes a tobacco liquid as an example. The atomizer <NUM> includes a smoking main body <NUM> which stores and atomizes a tobacco liquid, an aerosol mouthpiece rod <NUM> disposed on the smoking main body <NUM>, and a first mouthpiece cap <NUM> covering on the mouthpiece rod <NUM>, wherein the first mouthpiece cap <NUM> is provided for a user to inhale an aerosol. The above atomizer <NUM>, compared with the atomizer products of existing tabular electronic cigarettes, has better convenience in structure. The structure of the atomizer <NUM> of the tobacco liquid atomization type can refer to the sectional view shown in <FIG>.

In <FIG>, the smoking main body <NUM> includes a hollow cylindrical shell <NUM>, wherein the shell <NUM> includes an upper end close to the first mouthpiece cap <NUM> and a lower end away from the first mouthpiece cap <NUM>; the lower end of the shell <NUM> is open, and the open lower end is provided with an end cover <NUM>.

One part of the mouthpiece rod <NUM> penetrates through the upper end of the shell <NUM> to the interior of the shell <NUM> from the outside; the mouthpiece rod <NUM> is a hollow tubular structure, of which the hollow interior is configured as a smoke channel <NUM> for conveying a tobacco liquid aerosol; a liquid storage chamber <NUM> for storing a tobacco liquid is formed between the outer wall of the mouthpiece rod <NUM> penetrating into the interior of the shell <NUM> and the inner wall of the shell <NUM>.

The shell <NUM> is internally provided with an atomization member for sucking in the tobacco liquid from the liquid storage chamber <NUM> and then heating and atomizing the liquid; in particular, the atomization member includes a porous body <NUM> with internal micropores, which generally adopts microporous ceramics/foaming metals and the like materials. In the embodiment of <FIG>, the porous body <NUM>, designed to be cylindrical, is disposed on the lower end of the mouthpiece rod <NUM> coaxially with the mouthpiece rod <NUM>. The porous body <NUM> defines an axial through-hole internally, wherein an inner surface of the through hole is provided with a heating body <NUM>, and the through hole is communicated with the smoke channel2421 to convey smoke to the smoke channel <NUM>. The tobacco liquid in the liquid storage chamber <NUM> flows along the direction of arrow R1 to the outer surface of the porous body <NUM> and is absorbed, then is conveyed to the inner surface of the through hole through the internal micropores of the porous body <NUM>, and finally is heated and atomized by the heating body <NUM> to generate an inhalable tobacco liquid aerosol which is then conveyed to the smoke channel <NUM>.

In order to firmly hold the atomization member and prevent leakage of the tobacco liquid from the liquid storage chamber <NUM>, a silicon seat <NUM> is disposed between the atomization member and the inner wall of the shell <NUM>, not only to ease the mounting of the atomization member, but also to prevent leakage of tobacco liquid through apertures.

The end cover <NUM> is provided with a pair of electrode columns <NUM>, two ends of the heating body <NUM> are conductively connected to the electrode columns <NUM> through the conductive pins <NUM> respectively, such that the heating body <NUM> can be powered to normally work.

The end cover <NUM> further defines an air inlet, wherein the air inlet is defined opposite to the axial through hole of the porous body <NUM>; when a user sucks on the mouthpiece rod <NUM>, a negative pressure is generated inside the shell <NUM>, then external air gets inside the shell <NUM> through the air inlet and carries the tobacco liquid aerosol generated inside the porous body <NUM> to the smoke channel <NUM> of the mouthpiece rod <NUM> along the direction of arrow R2, until conveyed to the upper end of the mouthpiece rod <NUM> 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 <NUM>, preferably the mainboard <NUM> is further configured as a main circuit board besides mounting and fixing other subassemblies, which can save the internal space of the shell <NUM>; further, the function of the circuit board is integrated onto the mainboard <NUM>, the electrical conduction between the conductor <NUM> and the atomizer <NUM> may be realized by the conducting circuit printed on the mainboard <NUM>. 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 <NUM>, 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 <NUM>, referring to <FIG>, a mounting seat <NUM> is further disposed on the mainboard <NUM> to assist in the assembling between the atomizer <NUM> and the mainboard <NUM>, wherein the mounting seat <NUM> includes a groove structure (as directly shown in <FIG>) adapted to the lower end of the shell of the atomizer <NUM>, so that the atomizer <NUM> can be directly inserted into the mounting seat <NUM> to fix. Meanwhile, for the ease of supplying power to the atomizer <NUM>, the mainboard <NUM> is further provided with a conductive pin <NUM>, wherein the conductive pin <NUM> includes a first connection end <NUM> opposite to the atomizer <NUM>, the first connection end <NUM> is located inside the groove structure of the mounting seat <NUM>; when the atomizer <NUM> is inserted and connected into the mounting seat <NUM>, the electrode column <NUM> inside the atomizer <NUM> contacts the conductive pin <NUM> and is electrically conducted. A second connection end of the conductive pin <NUM> opposite to the first connection end <NUM> is conductively connected to the conductor <NUM> directly or indirectly through a lead.

In order to further avoid erroneously triggering when the atomizer <NUM> is at the second connection position B, the mainboard <NUM> is provided with an airflow sensor <NUM>; as shown in <FIG> and <FIG>, the airflow sensor <NUM> is disposed directly opposite to the air inlet on the end cover <NUM> of the atomizer <NUM>, and the distance between the airflow sensor <NUM> and the air inlet should ensure that the airflow sensor <NUM> is located on the smoke circulation path of sucking of the atomizer <NUM>, 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 <NUM> and the electrode column <NUM> of the atomizer <NUM>. If the airflow sensor <NUM> detects an air circulation which is generated when a user sucks on the mouthpiece rod <NUM> of the atomizer <NUM>, the airflow sensor <NUM> controls the switch circuit to turn on so as to supply power to the atomizer <NUM>; if the airflow sensor <NUM> does not detect an airflow, the switch circuit is off, preventing the atomizer <NUM> being erroneously triggered. Meanwhile, from the figure, the airflow sensor <NUM> is connected to the power source apparatus via the conductor <NUM> 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 invention 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 <NUM> and the elongated aerosol generating apparatus <NUM>; 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 <NUM> is designed to be protruded relative to the power source apparatus <NUM> when the aerosol generating apparatus <NUM> is at the second connection position B. Specifically referring to <FIG>, the atomizer <NUM> on the aerosol generating apparatus <NUM> is disposed on one end of the aerosol generating apparatus <NUM> along the length direction, and is disposed close to the proximal end of the power source apparatus <NUM>; when the aerosol generating apparatus <NUM> is at the second connection position B, at least one part of the first mouthpiece cap <NUM> of the atomizer <NUM> is protruded relative to the proximal end <NUM> of the power source apparatus <NUM>; the protruded design is more convenient for a smoker to perform a sucking action on the first mouthpiece cap <NUM>. Meanwhile, when the atomizer <NUM> is at the first connection position A, the atomizer <NUM> is level with the proximal end of the power source apparatus <NUM>, which is good looking and is easy for sanitary storage.

With the present electric heating smoking system in the present invention, 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 <NUM>.

From embodiments of <FIG>, the power source apparatus <NUM> and the aerosol generating apparatus <NUM> adopt a sliding connection along the length direction of the power source apparatus <NUM>; however, in other transformative embodiments, the sliding connection may be replaced with a similar moveable connection. For example, the aerosol generating apparatus <NUM> and the power source apparatus <NUM> are designed with a rotating connection on the contact surface, the conductive and non-conductive connections between the aerosol generating apparatus <NUM> and the power source apparatus <NUM> 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 invention, another embodiment of the present invention further provides an electric heating smoking system product, as shown in <FIG>, 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> and <FIG>, another end of the aerosol generating apparatus 20a opposite to the atomizer 24a along the length direction is provided with a charging member <NUM>; for convenient illustration, take a USB charging member commonly used by this type of products for example. The charging member <NUM> includes a USB interface <NUM>, a cap <NUM>, 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 <NUM> while the other end is connected to the conductor <NUM>; 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 <NUM>.

Further, referring to <FIG>, 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 <NUM> 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 <NUM>, 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 <NUM> 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 <NUM> of the charging member <NUM> 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 <NUM> into an adapted charging port.

It should be noted that, in embodiments of <FIG>, the aerosol generating apparatus <NUM>/20a is provided with one group of conductors <NUM>/20a only, which are in contact conduction with the first conductive contact 111a and the second conductive contact 112a of the power source apparatus <NUM>/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 <NUM> 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 invention further provides another electric heating smoking system; the electric heating smoking system product in the present embodiment can refer to <FIG> and <FIG> 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:.

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 <NUM> 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 <NUM> 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 <NUM> 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 <NUM> includes a smoking main body <NUM> which stores and atomizes a tobacco liquid, a second aerosol mouthpiece rod <NUM> disposed on the smoking main body <NUM>, and a second mouthpiece cap <NUM> covering on the second mouthpiece rod <NUM>, wherein the second mouthpiece cap <NUM> 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 <NUM> of the second atomizer <NUM> is protruded relative to the distal end 120b of the power source apparatus <NUM>;the protruded design is more convenient for a smoker to perform a sucking action on the second mouthpiece cap <NUM>. Meanwhile, when the second atomizer <NUM> is at the first connection position A, the atomizer <NUM> is level with the distal end 120b of the power source apparatus <NUM>, 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>. 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 <NUM>; the first atomizer 24b is inserted into the first mounting seat 251b to be fixed and assembled, the second atomizer <NUM> 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 <NUM> 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 <NUM> 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 <NUM> respectively, for sensing the airflows in respective smoke circulation paths when the first atomizer 24b and the second atomizer <NUM> are sucked respectively. It is to be noted that the corresponding smoke circulation path when the first atomizer <NUM> is sucked is called a first smoke circulation path, the corresponding smoke circulation path when the second atomizer <NUM> 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 <NUM> 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 <NUM>, 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 <NUM>, 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 <NUM> is sucked from the first airflow sensor 271b, thereby prevent mutual erroneous triggering. Specifically,.

the airflow isolating member <NUM> includes an airflow isolating body <NUM>, wherein the airflow isolating body <NUM> includes:.

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

Further, referring to <FIG>, for the ease of production and preparation, the first airflow isolating part <NUM> and the first airflow guide body <NUM> are combined and prepared as an integrated structure. The shape and design of the first airflow isolating part <NUM>, 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 <NUM>, which accommodates the first airflow sensor 271b therein, preventing the first airflow sensor 271b being interfered by the airflow of the second atomizer <NUM>. The first airflow guide body <NUM> includes a first airflow guide channel <NUM>, 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 <NUM> and the second airflow guide body <NUM> shown in <FIG> 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 <NUM> described in the embodiment of <FIG>. Specifically, the airflow isolating member <NUM> includes:
an airflow isolating board <NUM>, which from <FIG> 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 <NUM>, the second airflow sensor is disposed between the second atomizer 40c and the airflow isolating board <NUM>.

Further, referring to <FIG>, 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 <NUM> 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 <NUM> integrates functions of both the first airflow isolating part <NUM> and the second airflow isolating part <NUM> described in the above embodiment.

Further, in this embodiment, the first airflow guide body <NUM> and the second airflow guide body <NUM> are disposed separated from the airflow isolating board <NUM>. The structures of the first airflow guide body <NUM> and the second airflow guide body <NUM> are the same as those in <FIG>, 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 <NUM>/<NUM> 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>, a charging member 30b is disposed on the power source apparatus <NUM> correspondingly. In <FIG>, the shell of the power source apparatus <NUM>, 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.
