The electric heating smoking system product of an embodiment of the present invention is described by taking a flat cigarette type as an example in the following figures; and its structural ideas and uses can be extended to other types of electrically heated smoking system products, such as non-combustion, toasting, heating, and the like. An electrically heated smoking system of an embodiment is particularly shown with reference to fig. 2-3.

The system comprises a power supply device 10 and an aerosol-generating device 20 for generating aerosol, which are assembled by means of a detachable connection; fig. 2 is a schematic diagram of the power supply device 10 and the aerosol generation device 20 after being assembled, and fig. 3 is a schematic diagram of the power supply device 10 and the aerosol generation device 20 in a disassembled state.

The above power supply device 10 has a structure shown in fig. 4, on which a pair of conductive contacts 11 are provided; as can be seen from the figure, the conductive contact 11 includes two, corresponding to a positive electrode and a negative electrode, respectively, which are used 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 the battery body is not shown in the drawings because it is relatively common and located inside the battery body is not easily marked in the drawings.

The aerosol-generating device 20 is configured as shown in fig. 5, and first has an atomizer 24 for performing a smoking function to generate smoke to be inhaled by a smoker. The atomiser 24 is arranged to receive the aerosol-forming substrate and heat it so that it produces an aerosol which is consumed by the user. The aerosol-forming substrate may be a solid-based substrate or a liquid smoke-based substrate. A solid substrate such as a volatile tobacco material containing a volatile tobacco flavoring compound that is released from the substrate upon heating; the solid-based substrate may also include tobacco powders, granules, strips, flakes, and the like that emit smoke upon heating. The liquid tobacco tar base contains glycerin, propylene glycol, etc.

In order to cooperate with the implementation of the basic function of the atomizer 24, the aerosol-generating device 20 has a pair of electrical conductors 21 thereon for corresponding electrically conductive connection with the electrically conductive contacts 11. In order to enable the above 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, specifically a first connection position a and a second connection position B, which are shown in fig. 2 and fig. 6, respectively; wherein,

in the first connection position a shown in fig. 2, the conductive contacts 11 are in a non-conductive connection state in which the positions of the conductive bodies 21 corresponding to the conductive connection are staggered;

when the conductive contact 11 is located at the second connection position B shown in fig. 6, the conductive contacts are aligned and contacted with each other corresponding to the positions of the conductive bodies 21 to form a conductive connection state;

and the power supply device 10 and the aerosol-generating device 20 are both kept connected, not disconnected, in the first connection position a and the second connection position B.

In order to facilitate the power supply device 10 and the aerosol generation device 20 of the embodiment to be capable of being switched between two connection states, the power supply device 10 and the aerosol generation device 20 are movably connected; specifically, in the preferred embodiment shown in fig. 4 and 5, which is a sliding connection, the power supply device 10 is elongated and has a proximal end 110 and a distal end 220 opposite to each other along the length; a slide groove 13 is provided along the longitudinal direction extending from the proximal end 110 to the distal end 120, and a slide button 23 adapted to the slide groove 13 is provided on the aerosol-generating device 20, so that the power supply device 10 and the aerosol-generating device 20 can slide relative to each other by fitting the slide button 23 to the slide groove 13. In detail, the aerosol generation device 20 is hooked to the power supply device 10 by a hook 231 bent at the tip of the slider 23, and both the power supply device 10 and the aerosol generation device 20 are kept connected during sliding to prevent their separation.

In other embodiments, the positions of the slide grooves 13 and the slide fasteners 23 may be changed, specifically, the slide grooves 13 may be changed to be disposed on the gas mist generating device 20 and the corresponding slide fasteners 23 may be disposed on the power supply device 10. In other embodiments, the guiding connection structure of the sliding slot 13/sliding buckle 23 can be replaced by another guiding connection structure such as a push rod, as long as it is ensured that both the aerosol-generating device 20 and the power supply device 10 can provide directional guidance when moving between the first connection position a and the second connection position B.

In this movable connection mode, the first connection position a and the second connection position B are correspondingly arranged along the relative sliding direction, as shown in fig. 2 and 6, and the second connection position B of fig. 6 is obtained by sliding the gas mist generating device 20 along the longitudinal direction from the first connection position a of fig. 2 to the power supply device 10 by a certain stroke.

In the above embodiment, the gas mist generating device 20 and the power supply device 10 are overlapped in the longitudinal direction based on the aesthetic design in which the product gas mist generating device 20 and the power supply device 10 are equivalent in size in the longitudinal direction. However, in addition to the above preferred design, the gas mist generating device 20 and the power supply device 10 may be formed to have an X-shaped cross shape by forming a certain angle between the longitudinal direction thereof and the longitudinal direction thereof. Then, the sliding connection can be arranged.

In the above preferred embodiment, the slide path between the gas mist generating device 20 and the power supply device 10 at the first connection position a and the second connection position B is a linear stroke along the longitudinal direction; in other modified embodiments, the sliding path change may be designed to be an arc/bend shape, etc., as long as the conductive connection state can be changed in a sliding manner between the first connection position a and the second connection position B.

Meanwhile, in order to further 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 structurally designed; referring specifically to fig. 4 and 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 which is positioned in cooperation with the positioning hole 12; as further shown in fig. 4, the positioning holes 12 include two sets, namely a first set of positioning holes 121 for positioning the first connection position a and a second set of positioning holes 122 for positioning the second connection position B; when the spring pins are respectively slid to the first connection position a and the second connection position B, the spring pins 22 are respectively capable of being inserted into the corresponding positioning holes 12 under the elastic force to realize positioning. Of course, based on the same positioning function, the above positioning hole 12 and the pogo pin 22 in the embodiment can be replaced by a positioning column/groove, a limiting structure, etc. to guide the sliding position.

Based on the detailed structural and functional implementation, the detailed structure and assembly of the aerosol generating device 20 in this embodiment can be seen in the exploded schematic view of fig. 7, which includes a hollow outer case 210, in which a main substrate 220 is installed and an intermediate lid 230 for assisting the assembly and fixation of the main substrate 220 are accommodated; the slider 23 is disposed on the outer housing 210, and the conductive body 21 and the pogo pin 22 are disposed on the main substrate 220, and penetrate through the middle cover 230 and the corresponding mounting holes of the outer housing 210 until partially exposed out of the surface of the outer housing 210, so as to be connected to the conductive contact 11 and the positioning hole 12 of the power supply device 10. In addition, the main core function atomizer 24 is also connected to the main substrate 220, and is electrically connected to the conductor 21.

Specifically, the structure of the atomizer 24 and the fitting connection with the main substrate 220 are shown in fig. 7 and 8 in this embodiment. The atomizer 24 is illustrated as an example of a product type that stores tobacco tar and heats and atomizes, and includes a smoking main body 241 that stores tobacco tar and atomizes, an aerosol nozzle rod 242 provided on the smoking main body 241, and a nozzle cap 243 for covering the nozzle rod 242; the above atomizer 24 provides more convenient construction than existing flat aerosol atomizer products. The structure of the atomizer 24 of the smoke atomizing type can be seen in the sectional view shown in fig. 8.

In fig. 8, the smoking body 241 comprises a hollow cylindrical outer shell 2410, the outer shell 2410 having an upper end proximal to the nozzle cap 243 and a lower end distal from the nozzle cap 243; and the lower end of the outer shell 2410 is open, and an end cover 2412 is arranged at the open lower end.

A part of the nozzle rod 242 penetrates the upper end of the outer shell 2410 from the outside to the inside of the outer shell 2410; the mouthpiece rod 242 is a hollow tubular structure with an interior hollow configured as a smoke channel 2421 for transporting a tobacco aerosol; the mouthpiece rod 242 penetrates to a space between an outer wall of an inner portion of the outer housing 2410 and an inner wall of the outer housing 2410 to form an oil storage chamber 2411 for storing tobacco tar.

An atomization component for sucking tobacco tar from the oil storage cavity 2411 and heating and atomizing the tobacco tar is further arranged in the outer shell 2410; the atomizing assembly includes a porous body 2414 with pores therein, and is usually made of a material such as a porous ceramic/metal foam. In the embodiment of fig. 8, the porous body 2414 is a cylindrical structure and is disposed at the lower end of the nozzle stem 242 along the same axis as the nozzle stem 242. The porous body 2414 has an axially penetrating through hole, a heating element 2415 is disposed on the inner surface of the through hole, and the through hole is communicated with the flue gas channel 2412 for conveying flue gas to the flue gas channel 2412. The tobacco tar in the oil storage chamber 2411 flows in the direction of the arrow R1 to the outer surface of the porous body 2414, is absorbed, is conducted to the inner surface of the through hole through the micropores in the porous body 2414, is heated and atomized by the heating body 2415, generates tobacco tar aerosol for smoking, and is conveyed to the smoke passage 2412.

In order to stably maintain the atomization assembly and prevent the smoke oil in the oil storage cavity 2411 from leaking, a silica gel seat 2413 is further arranged between the atomization assembly and the inner wall of the outer shell 2410, so that the atomization assembly is convenient to mount, and the smoke oil is prevented from leaking from a gap.

A pair of electrode posts 2417 are arranged on the end cover 2412, and two ends of the heating body 2415 are respectively in conductive connection with the electrode posts 2417 through conductive pins 2416, so that power is supplied to the heating body 2415, and the heating body 2415 can work normally.

The end cover 2412 is further provided with an air inlet hole which is arranged opposite to the axial through hole of the porous body 2414, when the nozzle rod 242 is sucked, negative pressure is generated inside the outer shell 2410, so that outside air enters the outer shell 2410 through the air inlet hole, and enters the smoke channel 2421 of the nozzle rod 242 according to the direction of an arrow R2 and carries smoke aerosol generated in the porous body 2414 until the smoke aerosol is transmitted to the upper end of the nozzle rod 242 to be sucked; forming a complete flue gas circulation path.

In the above assembly and control of the structure of the aerosol-generating device 20, it is preferable that the main substrate 220 is configured to be used as a main circuit board in addition to being mounted and fixed as another component, so that the internal space of the outer case 210 can be saved, the function of the circuit board is integrated into the main substrate 220, and the electric conduction between the electric conductor 21 and the atomizer 24 can be communicated through the electric conduction line printed on the main substrate 220. Compared with a mode of realizing conduction by needing an additional conductive lead when the function of a circuit board is not available, the design has better convenience; on the other hand, the circuit board arranged on the power supply part in the original flat cigarette product can be transferred into the aerosol generating device 20, so that the structural space of the power supply part is saved and the convenience of assembly is improved.

Also in this embodiment, conductive fitting and false triggering are facilitated based on further control of the atomizer 24, see fig. 7; a mounting seat 25 for assembling the auxiliary atomizer 24 with the main substrate 220 is further provided on the main substrate 220, and the mounting seat 25 has a groove structure (directly seen in fig. 7) adapted to the lower end of the outer housing of the atomizer 24, so as to facilitate the direct insertion and fixation of the atomizer 24 into the mounting seat 25. Meanwhile, in order to facilitate power supply to the atomizer 24, a conductive pin 26 is further disposed 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, and when the atomizer 24 is plugged onto the mounting seat 25, the electrode column 2417 in the atomizer 24 is in contact with the conductive pin 26 for conducting electricity. And a second connection end of the conductive pin 26 opposite to the first connection end 261 is electrically connected to the conductive body 21 directly or indirectly through a lead.

Further to avoid the false triggering when the atomizer 24 is in the second connection position B, the main substrate 220 is provided with the airflow sensor 27, as can be seen from fig. 7 and 8, the airflow sensor 27 is disposed at a position right opposite to the air inlet hole on the end cover 2412 of the atomizer 24, and a position spaced from the air inlet hole is ensured to be on the smoke circulation path when the atomizer 24 sucks, so that the airflow flow during smoking can be sensed; meanwhile, a switching circuit (not shown) is provided between the conductor 21 and the electrode shaft 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 flow, the control switch circuit is conducted to supply power to the atomizer 24; when the airflow sensor 27 does not detect the airflow, the switch circuit is turned off, and the atomizer 24 is prevented from being triggered by mistake. Meanwhile, 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. Compare and set up the sensor in current classic flat cigarette and stabilize electrically conductive normally open mode on power supply unit's circuit board, more can guarantee to prevent the life who triggers by mistake and improve the sensor.

The above sliding connection and positioning are preferable designs based on the shapes of the elongated power supply device 10 and the aerosol-generating device 20 employed in the embodiments; in other types of shapes or products, the movable connection mode can be changed into rotary connection and the like according to the shape of the product, as long as the connection position with the conductive and non-conductive states can be ensured.

Further, in order to facilitate the smoking action of the product in the conductive state of the second connecting position B; in the design, the atomizer 24 is in a protruding state with respect to the power supply device 10 when the aerosol-generating device 20 is in the second connection position B. Referring specifically to figure 6, the atomizer 24 of the aerosol-generating device 20 is disposed at one end of the aerosol-generating device 20 in the longitudinal direction thereof and is disposed adjacent 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 is more convenient for a smoker to suck on the mouthpiece cap 243. Also, it can be seen that when the atomizer 24 is in the first attachment position A, it is flush with the proximal end of the power supply unit 10 for aesthetic and hygienic storage.

Adopt the utility model discloses an above electrical heating system of being fuming compares current electron cigarette product, and power supply unit and aerial fog generate the device and pass through swing joint, adjust the electrically conductive/non-conductive state under the connected state to guarantee the security and eliminate the possibility that aerial fog generates device 100 false triggering.

A different variation of this embodiment is an aerosol-generating device 20b having a first atomizer 24b and a second atomizer 40 provided at opposite ends in the longitudinal direction, respectively; wherein,

the first atomizer 24B is configured to electrically connect with the power supply device 10B to effect suction when in the second connection position B, and the second atomizer 40 is configured to electrically connect with the power supply device 10B to effect suction when in the third connection position C; also, from the same standpoint as in the above embodiment, the first atomizer 24B protrudes with respect to the proximal end 110B of the power supply device 10B when corresponding to the second connection position B; the second atomizer 40 is correspondingly protruded relative to the distal end 120b of the power supply unit 10b in the third connection position C, thereby facilitating the sucking suction of the smoker.

In this embodiment, the fixed assembly and operational 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 in the relative sliding direction of the gas mist generator 20b and the power supply device 10; the first atomizer 24b is fixedly assembled by being inserted into the first mounting seat 251b, and the second atomizer 40 is fixedly assembled by being inserted into the second mounting seat 252 b; the corresponding main substrate 220b is further provided with a first conductor pin 26b and a second conductor pin 28b for electrically connecting the conductor 21b with the first atomizer 24b and the second atomizer 40, respectively.

Meanwhile, a first air flow sensor 271b for controlling the operation of the first atomizer 24b and a second air flow sensor 272b for controlling the operation of the second atomizer 40, respectively, are provided on the main substrate 220 b. The first air flow sensor 271b and the second air flow 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 for respectively sensing the air flows in the smoke circulation path when the first atomizer 24b and the second atomizer 40 respectively perform suction. In addition, in accordance with the idea of controlling the operation of each atomizer by triggering the airflow sensor, the switching circuit described in the above embodiments may be added to the circuit portion of the main substrate 220 to trigger the conduction of each switching circuit through the airflow sensor, so as to supply power to the atomizer, thereby preventing false triggering.

Further in this embodiment, since the first airflow sensor 271b and the second airflow sensor 272b are shown to be located on a straight line in the length direction, when the distance between the two is not far enough, there is a possibility that the first airflow sensor 271b may sense the airflow flowing in the smoke circulation path when the second atomizer 40 sucks, or conversely, the second airflow sensor 272b may sense the airflow flowing in the smoke circulation path when the first atomizer 24b sucks, and false triggering occurs; in this embodiment, therefore, the main substrate 220b is further provided with airflow isolation members 50 for isolating the airflow generated when the first atomizer 24b sucks from the second airflow sensor 272b and the airflow generated when the second atomizer 40 sucks from the first airflow sensor 271b, respectively, so as to prevent mutual false triggering. In particular, the method comprises the steps of,

the airflow isolation assembly 50 includes an airflow isolation body 51, and the airflow isolation body 51 includes:

a first airflow isolation portion 511 for isolating the airflow generated when the first atomizer 24b sucks from the second airflow sensor 272 b;

the second air flow isolation portion 512 is configured to isolate the air flow generated when the second atomizer 40 sucks from the first air flow sensor 271 b.

Meanwhile, further to facilitate accurate sensing of the airflow drawn by the airflow sensor and the corresponding atomizer, the airflow isolating assembly 50 is added with a functional structure for airflow guiding. Specifically, the structure of the air flow guide includes:

a first airflow guide 521 for guiding the airflow sucked by the first atomizer 24b to the first airflow sensor 271b to be sensed;

a second air flow guiding body 522 for guiding the air flow sucked by the second atomizer 40 to the second air flow sensor 272 to be sensed.

With further reference to fig. 15, the first gas flow separator 511 and the first gas flow guiding body 521 are combined and prepared as an integral structure for the convenience of production and preparation. On the one hand, the shape and design concept of the first airflow isolating part 511 can shield the airflow at the air inlet of the first atomizer 24b and prevent the airflow from flowing to the second airflow sensor 272 b; on the other hand, it is formed with an accommodating chamber 5111, and this accommodating chamber 5111 accommodates therein the first air flow sensor 271b, preventing the first air flow sensor 271b from being disturbed by the air flow of the second atomizer 40. The first air flow guiding body 521 has a first air flow guiding passage 5211, one end of which is connected to the first air flow sensor 271b and the other end of which is connected to the air inlet of the first atomizer 271b, thereby forming an air flow guiding function.

The second airflow partition 512 and the second airflow guide 522 are prepared in the same integrated manner in fig. 14, and a description thereof will not be repeated.

In another embodiment, the flow separation between the two atomizers is performed using another flow separation assembly 60 as described in the embodiment of fig. 16. Specifically, the method comprises the following steps:

an airflow isolation plate 61, seen in fig. 16, disposed along the opposite middle of the first atomizer 24c and the second atomizer 40c, in this position isolating the airflow generated by the respective atomizers; and the first air flow sensor 271c is disposed between the first atomizer 24c and the air flow separation plate 61, and the second air flow sensor is disposed between the second atomizer 40c and the air flow separation plate 61.

With further reference to fig. 16, the first airflow sensor 271c is located on the fume circulation path Q1 when the first atomizer 24c is drawing, sensing its drawing action; and the second airflow sensor 272b is located on the smoke circulation path Q2 when the second atomizer 40c sucks, and senses the sucking action thereof; and the gas flow separating plate 61 separates the flue gas circulation paths Q1 and Q2 from each other, thereby isolating the mutual interference of the gas flows. This air flow separation plate 61 is integrated with the functions of both the first air flow separation portion 511 and the second air flow separation portion 512 in the above embodiment based on the design concept.

Further in this embodiment, the first air flow guide 621 and the second air flow guide 622 are provided separately from the air flow separation plate 61. The structure is the same as the design of fig. 14 and 15 and will not be described again.

It should be noted that the shapes and configurations of the components in the above airflow isolating assembly 50/60 may be correspondingly changed and adjusted in combination with the structure of the main substrate 220b and the spatial arrangement of the components thereon in other different implementation scenarios, and the specific shapes are not limited as long as the requirements for mutual airflow isolation to prevent the above-mentioned interference situation can be met.

Further, both ends of the gas mist generating device 20b having the above structure are designed as atomizers, and a charging module cannot be added, and in order to ensure a charging function of the power supply device 10b when the product is used, as shown in fig. 17, a charging unit 30b is provided on the power supply device 10. In fig. 17, the conventional structure of the case, the battery main body (not shown), and the like of the power supply device 10b is not described in detail in this document. The charging assembly 30b comprises a charging interface 31b, a charging circuit board 32b and an electrode connecting pin 33 b; the charging interface 31b is adapted to a charging line interface of a charger, the charging circuit board 32b realizes electric energy conversion, and the electrode connecting pin 33b is used for electrode connection of the battery main body; the entire combination realizes the charging function of the power supply device 10 b.

In the above dual atomizer structure, based on similar usage scenarios, the first atomizer 24b and the second atomizer 40 may be heated by tobacco tar, promoted or replaced by a type of tobacco/volatile substance heating cigarette, and may have different tobacco tar tastes from each other, so as to satisfy more diverse smoking experiences of smoking users of electronic cigarettes. When in use, the power supply device 10b supplies power to heat and smoke after the corresponding conductive contacts 111b/112b are conducted through the conductor 21 b.
