[0129] At least one or more magnetic field generators 30 are arranged between the receiving cavity 510 and the rear side 160; at least one or more magnetic field generators 30 can be powered by the main circuit board 20. Figures 2 to 8 In the illustrated embodiment, at least one or more magnetic field generators 30 are configured as electromagnetic induction heaters capable of generating a changing magnetic field to induce heating of the substrate 241 of the aerosol generating article 200 through the magnetic field. When the aerosol generating article 200 is received in the receiving cavity, at least one or more magnetic field generators 30 induce heating of the aerosol generating article 200 by generating a magnetic field.

[0130] according to Figures 2 to 10 As shown in , when the aerosol generating article 200 is received in the receiving chamber 510, each of the plurality of magnetic field generators 30 is respectively opposite to two aerosol generating substrates 242 and / or bases 241, so that each magnetic field generator 30 can heat the two opposite bases 241 at the same time.

[0131] exist Figures 2 to 10 In the illustrated embodiment, the magnetic field generator 30 is substantially planar. In an embodiment, the magnetic field generator 30 comprises a planar spiral coil 30. And, the substrate 241 is planar. When the aerosol generating article 200 is received in the receiving cavity, the magnetic field generator 30 is substantially arranged parallel to the substrate 241. Figures 2 to 10 In the embodiment, the base 241 is circular in shape. Or in some other variations, the base 241 is square, oval, etc.

[0132] In some embodiments, when the aerosol generating article 200 is received in the receiving chamber, the planar spiral coil 30 is substantially arranged in parallel with the substrate 241. And the spacing between the planar spiral coil 30 and the substrate 241 is less than 15 mm; more preferably, the spacing between the planar spiral coil 30 and the substrate 241 is less than 10 mm. In some embodiments, the spacing between the planar spiral coil 30 and the substrate 241 is less than the diameter of the substrate 241.

[0133] according to Figures 2 to 10 In the illustrated embodiment, the plurality of planar spiral coils 30 are substantially arranged discretely. The plurality of planar spiral coils 30 are substantially all in the same plane. In some embodiments, at least one or more planar spiral coils 30 are arranged discretely or in an array. In some embodiments, the plurality of planar spiral coils 30 are arranged at intervals along the longitudinal direction of the heating device 100.

[0134] exist Figures 2 to 10 In the embodiment, the planar spiral coil 30 is arranged in a shape similar to a racetrack or an ellipse; Figures 2 to 10 As shown, the planar spiral coil 30 has a length direction and a width direction perpendicular to the length direction; a length dimension W11 of the planar spiral coil 30 along the length direction is greater than a width dimension W12 along the width direction.

[0135] exist Figures 2 to 10 In the embodiment, after assembly, the length direction of the planar spiral coil 30 is arranged perpendicular to the longitudinal direction of the heating device 100; the length direction of the planar spiral coil 30 is substantially parallel to the width direction of the heating device 100. Alternatively, the extension dimension of the planar spiral coil 30 along the width direction of the heating device 100 is greater than the extension dimension along the longitudinal direction of the heating device 100.

[0136] according to Fig.10 As shown in , the planar spiral coil 30 may include a first region 310 and a first region 320 along the length direction. When the aerosol generating article 200 is received in the heating device 100, one substrate 241 is opposite to the first region 310, and another substrate 241 is opposite to the first region 320. In use, when each planar spiral coil 30 generates a magnetic field, it can simultaneously induce the two opposite substrates 241 to form eddy current heating to heat the aerosol generating substrate 242 located on the substrate 241 to generate aerosol, which is beneficial for increasing the amount of total particulate matter (TPM) supplied to the user in each puff.

[0137] In some embodiments, each of at least one or more planar spiral coils 30 can be independently connected to the first portion 21 of the main circuit board 20, and thus can be independently powered by the main circuit board 20. For example, in some embodiments, a plurality of planar spiral coils 30 are connected to the main circuit board 20, and then the main circuit board 20 can independently provide alternating current to make the plurality of planar spiral coils 30 independently generate magnetic fields, thereby independently starting heating. For example, in some embodiments, several or more planar spiral coils 30 are independently startable; so that each planar spiral coil 30 can only heat two opposing substrates 241 individually, so that the aerosol generating substrates 242 on the two substrates 241 are heated to generate aerosol. For another example, in some embodiments, the main circuit board 20 is configured to control several or more planar spiral coils 30 to be started to heat one after another in a predetermined order. In some embodiments, the main circuit board 20 is configured to control several or more planar spiral coils 30 not to start heating at the same time; so that, for example, when the user takes a puff each time, the main circuit board 20 only controls one planar spiral coil 30 to start heating to generate an aerosol that satisfies one puff. In some embodiments, in each puff, the main circuit board 20 controls one of the several planar spiral coils 30 to heat the two substrates 241 of the aerosol-generating article 200 separately, and the amount of total particulate matter (TPM) generated may be at least 1.5 mg, at least 1.7 mg, at least 2.0 mg, at least 2.5 mg, at least 3.0 mg, about 1.0 mg to about 5.0 mg, about 1.5 mg to about 4.0 mg, about 2.0 mg to about 4.0 mg or about 2.0 mg to about 3.0 mg, at least 3 mg to about 7 mg, about 4 mg to about 8 mg, and about 5 mg to about 10 mg.

[0138] In some embodiments, during multiple puffs by the user, the main circuit board 20 controls a predetermined sequence of the plurality of planar spiral coils 30 to start heating one after another in sequence. Figures 2 to 10As shown in: when the user takes the first puff, the main circuit board 20 provides power to the first planar spiral coil 30 from top to bottom for heating, so as to heat the two relative substrates 241 and the aerosol generating matrix 242 to generate an aerosol for one puff; when the user takes the next puff, the main circuit board 20 provides power to the second planar spiral coil 30 from top to bottom for heating, so as to heat the relative substrate 241 and the aerosol generating matrix 242 to generate an aerosol for one puff; and this is performed sequentially until all the planar spiral coils 30 are heated, and all the aerosol generating matrix 242 in the aerosol generating product 200 has been consumed, prompting the user to replace the new aerosol generating product 200. In the above implementation, starting the planar spiral coils 30 separately in sequence instead of starting the heating at the same time means minimizing the unnecessary consumption of the aerosol generating matrix and reducing the waste of energy. Or in some other implementations, the order in which the plurality of planar spiral coils 30 are started in sequence according to a predetermined order is performed along the arrangement direction.

[0139] Or in some other implementation variations, the main circuit board 20 controls the plurality of planar spiral coils 30 to be started up individually in sequence, without intervals along the arrangement direction of the planar spiral coils 30. Or in some other implementation variations, the main circuit board 20 controls the plurality of planar spiral coils 30 to be started up individually in sequence, with intervals or in jumps.

[0140] In some embodiments, several or more planar helical coils 30 can be energized sequentially, ie, once per user puff, so as to consistently generate an aerosol on a puff-by-puff basis.

[0141] In some embodiments, the heating device 100 includes:

[0142] An airflow sensor (not shown in the figure), such as a microphone or a MEMS sensor, is used to sense the user's puffing action. The main circuit board 20 sequentially supplies energy to a plurality of planar spiral coils 30 based on the sensing result of the airflow sensor. In a preferred embodiment, the main circuit board 20 controls a plurality of planar spiral coils 30 to start sequentially in a predetermined order, which is performed according to the user's puffing action. And in some other variations, the main circuit board 20 controls the sequential start of a plurality of planar spiral coils 30, which is performed according to a predetermined interval time; for example, the predetermined interval is between about 30 seconds and 300 seconds.

[0143] In some embodiments, the main circuit board 20 controls a plurality of planar spiral coils 30 to start sequentially in a predetermined order, which is based on the removal or replacement of the aerosol generating product 200. Specifically, in some embodiments, after the main circuit board 20 controls the above planar spiral coils 30 to start sequentially, the user is prompted that the aerosol generating product 200 has been consumed, and the user is prompted to replace the aerosol generating product 200 with a new one.

[0144] Or in some embodiments, when it is detected that a new aerosol generating product 200 is received in the receiving chamber of the heating device 100, the planar spiral coil 30 is restarted in sequence according to a predetermined order. The detection of the user replacing a new aerosol generating product 200 can be detected by a sensor; for example, the aerosol generating device is provided with a light sensor or a pressure sensor, etc., for sensing the aerosol generating product 200 being combined with or removed from the receiving chamber, and determining the user's replacement or consumption of the aerosol generating product 200 according to the combination and removal.

[0145] In some embodiments, the main circuit board 20 controls the planar spiral coils 30 to start sequentially, which is cyclic. For example, in some embodiments, the cycle is performed according to a predetermined number of times; for example, 3 times. Specifically, when the number of times the planar spiral coils 30 are started, and / or the number of puffs of the user, reaches a predetermined number of times, a new cycle is entered to control the planar spiral coils 30 to start sequentially. For another example, in some embodiments, the cycle is performed according to the removal or replacement of the aerosol generating article 200.

[0146] In some embodiments, the main circuit board 20 controls a plurality of planar spiral coils 30 to generate a magnetic field to induce the relative substrate 241 to be heated according to the same heating curve. For example, in some specific embodiments, the main circuit board 20 controls the generation of a magnetic field to induce the relative substrate 241 to be heated at a temperature of 300°C. Or in some other variant embodiments, the main circuit board 20 controls a plurality of planar spiral coils 30 to induce the relative substrate 241 to be heated according to different heating curves or heating temperatures. For example, in some implementations, the main circuit board 20 controls a plurality of planar spiral coils 30 to induce the heating temperature of the relative substrate 241 to increase or decrease sequentially along the heating start sequence.

[0147] For example, in some embodiments, the main circuit board 20 is configured to sequentially supply power to the planar spiral coil 30 at a given power, so that the relative substrate 241 reaches the operating temperature within a predetermined time. For example, each time the main circuit board 20 supplies power to the planar spiral coil 30, the relative substrate 241 reaches a temperature of at least about 200 degrees, or at least 300 degrees, or at least 400 degrees within 0.5 seconds, and stops after maintaining for about 2.5 seconds.

[0148] In some embodiments, each planar spiral coil 30 is continuously spirally wound by a low-resistivity wire material, for example, the planar spiral coil 30 is spirally wound by a conductive copper wire or silver wire. In some embodiments, the wire material wound by the planar spiral coil 30 has a circular cross-sectional shape; or in other embodiments, the wire material wound by the planar spiral coil 30 has a rectangular, elliptical or triangular cross-sectional shape. In some embodiments, the wire material wound by the planar spiral coil 30 is a Litz wire having multiple or multiple strands of conductive wires.

[0149] Or in some other embodiments, the planar spiral coil 30 is a track or line formed on a flat surface of a substrate by printing, depositing or spraying a conductive paste. For example, in some specific embodiments, the planar spiral coil 30 is formed in a thin layer by printing, depositing or spraying on a rigid or flexible electrical insulating substrate such as ceramic, glass, quartz or PI film.

[0150] according to Fig.10 As shown in the figure, when the aerosol generating product 200 is received in the receiving cavity 510, the projections of the two substrates 241 opposite to the planar spiral coil 30 are both located inside the planar spiral coil 30, which is beneficial for preventing magnetic leakage and improving the utilization of magnetic energy.

[0151] exist Figures 2 to 10 In the embodiment, each substrate 241 has a diameter of about 6 to 12 mm; the planar spiral coil 30 also has a width dimension W12 of about 6 to 12 mm. In addition, the length dimension W11 of the planar spiral coil 30 is greater than twice the diameter of the substrate 241 of about 6 to 12 mm; for example, in some embodiments, the length dimension W11 of the planar spiral coil 30 is about 15 to 30 mm.

[0152] according to Figures 2 to 5 As shown, a plurality of meshes 2411 are arranged on the substrate 241, so that the substrate 2411 is fluid-permeable. In some embodiments, the substrate 241 with meshes 2411 is formed by mechanically punching, chemically etching holes, laser punching, etc. in a dense sheet precursor; mechanical punching is such as punching, drilling with a drill, etc. The mesh substrate 241 is advantageous in that the heat on the substrate 241 can be formed and distributed more evenly during hysteresis heating. In some embodiments, the mesh 2411 is square in shape, and the side length of the square mesh 2411 is between 0.5 and 1.5 mm; more preferably, the side length of the mesh 2411 is between 1.0 and 1.4 mm.

[0153] In some embodiments, the ratio of the area of ​​the mesh 2411 on the substrate 241 to the area of ​​the circular substrate 241 is greater than 25%; in some specific embodiments, the ratio of the area of ​​the mesh 2411 on the substrate 241 to the area of ​​the substrate 241 is between 30% and 60%.

[0154] according to Figures 2 to 10 As shown, in the embodiment, one of the two substrates 241 opposite to each planar spiral coil 30 is located or exposed in the first air channel R21, and the other is located or exposed in the second air channel R22. Then, in each inhalation, when the main circuit board 20 controls one planar spiral coil 30 to heat, aerosol can be formed and outputted in both the first air channel R21 and the second air channel R22 of the aerosol generating product 200. Alternatively, when the main circuit board 20 controls one planar spiral coil 30 to heat, aerosol output is generated in only one of the first air channel R21 and the second air channel R22 of the aerosol generating product 200, and no aerosol output is generated in the other. Alternatively, each planar spiral coil 30 spans the first air channel R21 and the second air channel R22 in length, so that when each planar spiral coil 30 starts heating, aerosol can be formed and outputted in the first air channel R21 and the second air channel R22 at the same time.

[0155] according to Figures 2 to 9 As shown, the aerosol generating article 200 can only be received in the receiving cavity 510 in a predetermined direction; specifically, the outer body 230 of the aerosol generating article 200 is arranged asymmetrically in both the length direction and the width direction. The substantially square outer body 230 has a cutout 260 at one of its corners; in an embodiment, the cutout 260 of the outer body 230 is defined by the cover plate 231 and the tray 232. Accordingly, the receiving cavity 510 has an inclined boundary 511 adapted to the cutout 260. Thus, in use, the aerosol generating article 200 can only be received in the receiving cavity 510 along a predetermined direction, such as Figure 2 Also, the inclined border 511 is used to abut against or fit into the cutout 290 of the aerosol generating article 200 .

[0156] according to Figures 2 to 9 As shown, when the aerosol generating article 200 is received in the receiving chamber 510 according to a predetermined direction, the cover plate 231 of the outer body 230 is facing or close to the front side 150, and the tray 232 is facing or close to the rear side 160 / the planar spiral coil 30. And in use, the aerosol generating substrate 242 is heated by the substrate 241 to generate an aerosol, and then passes through the mesh 2411 of the substrate 241 and is released into the first air channel R21 and / or the second air channel R22, as shown in FIG. Figure 4As shown by the arrow R4 in the middle. In this embodiment, the aerosol generating substrate 242 provides isolation between the tray 232 and the base 241 to prevent the heat of the base 241 from being transferred to the tray 232. In addition, the first air channel R21 and / or the second air channel R22 provide thermal insulation between the base 241 and the cover plate 231 to prevent the heat of the base 241 from being transferred to the cover plate 231. In this embodiment, the first side surface and the second side surface of the base 241 opposite to each other in the thickness direction are not in contact with the outer body 230 of the aerosol generating article 200, so as to maximize the prevention of heat transfer between them.

[0157] Fig.11 A schematic diagram of an aerosol generating article 200a in an aerosol generating system in another embodiment is shown; in this embodiment, the aerosol generating article 200a, which is substantially in the form of a sheet or a box, comprises:

[0158] An outer body, defining an outer surface of the aerosol generating article 200a; and, the outer body comprises a cover plate 231a and a tray 232a opposite to each other in a thickness direction; the tray 232a is provided with a first air outlet 261a and a second air outlet 262a isolated from each other at a first end; the tray 232a is provided with a first air inlet 251a and a second air inlet 252a isolated from each other at a second end;

[0159] A plurality of concave cavities 271a are arranged at intervals in the longitudinal direction of the aerosol generating article 200a on the surface of the tray 232a facing the cover plate 231a; in this embodiment, the plurality of concave cavities 271a extend from one side to the other side in the width direction of the aerosol generating article 200a; and the concave cavities 271a are arranged to extend along the width direction of the aerosol generating article 200a. Alternatively, the length dimension of the concave cavities 271a is greater than the width dimension; and the length direction of the concave cavities 271a is perpendicular to the length direction of the aerosol generating article 200a;

[0160] A plurality of substrates 241a are arranged in the concave cavity 271a respectively; the substrates 241a are adapted to the shape of the concave cavity 271a; the substrates 241a are arranged to extend along the width direction of the aerosol generating article 200a. Alternatively, the length dimension of the substrate 241a is greater than the width dimension.

[0161] When the aerosol generating article 200a is received in the heating device 100, one of the plurality of substrates 241a is arranged parallel to and opposite to one of the plurality of planar spiral coils 30, so that it can be penetrated by the magnetic field generated by the opposite planar spiral coil 30 to form eddy current heating.

[0162] In this embodiment, the size or shape of the substrate 241a is substantially equal to the size or shape of the racetrack-shaped planar spiral coil 30. Alternatively, in this embodiment, the substrate 241a and / or the concave cavity 271a are configured to be in a racetrack or elliptical shape. Each substrate 241a is configured to be in a mesh shape and includes a first heating portion 2411a and a second heating portion 2412a arranged in the length direction; the first heating portion 2411a and the second heating portion 2412a are in a mesh shape with meshes. The substrate 241a also includes a dense spacing area 2413a located between the first heating portion 2411a and the second heating portion 2412a.

[0163] according to Fig.11 As shown, the aerosol generating article 200a further comprises:

[0164] A plurality of discrete aerosol generating substrates 242a are respectively bonded to a plurality of substrates 241a; during use, each of the substrates 241a is penetrated by the changing magnetic field and generates heat, thereby heating the aerosol generating substrates 242a bonded thereto to generate aerosols.

[0165] In this embodiment, two spaced aerosol generating substrates 242a are arranged or combined on each substrate 241a; specifically, of the two aerosol generating substrates 242a on each substrate 241a, one is located or combined on the first heating portion 2411a and is heated by the first heating portion 2411a to form an aerosol, and the other is located or combined on the second heating portion 2412a and is heated by the second heating portion 2412a to form an aerosol. When each of the substrates 241a is penetrated by the changing magnetic field generated by the relative planar spiral coil 30 and generates heat, the two aerosol generating substrates 242a combined thereon can be heated simultaneously to generate aerosol. The aerosol generated by heating one of the two aerosol generating substrates 242a is released into the first air channel and then output from the first air outlet 261a, and the aerosol generated by heating the other is released into the second air channel and then output from the second air outlet 262a.

And in this embodiment, each substrate 241b can be penetrated by the changing magnetic field generated by the planar spiral coil 30 to generate heat, thereby heating the aerosol generating matrix 242b located or combined thereon. In this embodiment, the aerosol generating matrix 242b is substantially equal to the shape or size of the substrate 241b. Then, in the embodiment, when each of the substrates 241a is penetrated by the changing magnetic field generated by the relative planar spiral coil 30 to generate heat, the aerosol generating matrix 242b combined thereon can be heated to generate aerosol. A portion of the aerosol generated by heating the aerosol generating substrate 242 b is released into the first air channel and then output from the first air outlet 261 , and another portion of the aerosol is released into the second air channel and then output from the second air outlet 262 .
