[0041] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The terms "connected" and "coupled" used in the present application, unless otherwise specified, both include direct and indirect connections and couplings.

[0042] An embodiment of the present application provides a heating device, which is used to heat an aerosol generating article 50 to generate aerosol.

[0043] In some embodiments, with reference to Figure 1-3, the heating device includes a heating cup 10, a main shell 40 and a zoned heating mechanism 30. Along the circumference of the heating cup 10, the side wall of the heating cup 10 is provided with a plurality of heating zones 11, and the heating cup 10 is configured to have an opening 12 at one end to accommodate the aerosol generating product 50 inserted from the opening 12; a heating chamber 21 is formed in the main shell 40, and the heating cup 10 is arranged in the heating chamber 21; the zoned heating mechanism 30 includes one or more heating elements 31, the heating element 31 is arranged on the side of the heating cup 10 facing the heating chamber 21, the heating element 31 extends along the axial direction of the heating cup 10, and has a preset arc length in the circumference of the heating cup 10, and the zoned heating mechanism 30 is configured to make the heating element 31 heat different heating zones 11 in different time periods.

[0044] When the heating device of the embodiment of the present application is used, the aerosol generating product 50 is inserted into the heating cup 10 from the opening 12, and the zoned heating mechanism 30 causes the heating element 31 to heat different heating zones 11 in different time periods. In this way, any heating zone 11 can be prevented from being heated continuously, thereby preventing the portion of the aerosol generating product 50 that is close to or in contact with the heating zone from being repeatedly heated, causing the aerosol generating product 50 to have an obvious burnt smell in the later stage of the puff, affecting the overall sensory perception, and reducing the pleasure and comfort. The heating device realizes zoned heating through the heating element 31. Compared with the traditional method of heating the entire aerosol generating product, the aerosol generating product 50 of the present application is heated only at the same time in the portion that is close to or in contact with the heated heating zone, so the preheating time is shorter, which can reduce the waiting time for consumers.

[0045] In the embodiment of the present application, the heating element 31 extends along the axial direction of the heating cup 10 and has a preset arc length in the circumferential direction of the heating cup 10. One heating element 31 can face at least one heating zone 11, and one heating element 31 can heat at least one heating zone. Alternatively, at least two heating elements 31 face one heating zone 11, and at least two heating elements 31 heat one heating zone 11 together. The corresponding relationship between the heating element 31 and the heating zone 11 can be set according to the specific use requirements.

[0046] In some embodiments, the heating element 31 can be a variety of achievable structures, for example, Figure 1 As shown, the heating element 31 is a resistance structure, which is arranged between the heating cup 10 and the heating chamber 21, or the resistance structure is arranged on the heating cup 10 or the heating chamber 21, wherein the resistance structure is, for example, a resistance heating sheet. In other embodiments, the heating element 31 can also be a radiation heating element, which is, for example, a circumferential heating source such as infrared, laser, or electromagnetic emission source.

[0047] In some embodiments, the heating element 31 uses a metal sheet as a resistance heating sheet. The metal sheet conducts heat, is heated more evenly, and has a shorter heating time, which helps to meet the usage requirement of "instant extraction and instant stop".

[0048] In some embodiments, the zone heating mechanism 30 further includes a driving member 34. The driving member 34 is drivingly connected to the heating cup 10 or the heating element 31. The driving member 34 is configured to drive the heating cup 10 and the heating element 31 to rotate relative to each other, so that different heating zones 11 face the heating element 31 and are heated by the heating element 31.

[0049] As Figure 1 , in a heating device according to an embodiment of the present application, when the driving member 34 is drivingly connected to the heating cup 10, the driving member 34 drives the heating cup 10 to rotate, so that the heating cup 10 and the heating element 31 rotate relative to each other. In other embodiments, when the driving member 34 is drivingly connected to the heating element 31, the driving member 34 drives the heating element 31 to rotate, so that the heating cup 10 and the heating element 31 rotate relative to each other. When the heating device according to the embodiment of the present application is in use, the driving member 34 is used to align different heating zones 11 with the heatable heating element 31 to achieve automatic adjustment of relative rotation.

[0050] In some embodiments, the heating device further includes a power supply member. The heating element 31 is electrically connected to the power supply member through a cable. After being powered on, the heating element 31 can heat the heating zone 11 it faces.

[0051] As Figure 10 , in some embodiments, along the radial direction of the heating cup 10, the distance L1 between the heating cup 10 and the heating element 31 satisfies: 0.1 mm ≤ L1 ≤ 0.2 mm. When the distance L1 between the heating cup 10 and the heating element 31 is within the above range, L1 is more appropriate. It can not only enable the heating cup 10 and the heating element 31 to rotate relative to each other and avoid wear caused by interference, etc., but also has the advantage of fast heat transfer from the heating element 31 to the heating zone 11 due to the small distance.

[0052] In some embodiments, along the radial direction of the heating cup 10, the distance L2 between the cavity wall of the heating chamber 21 and the heating element 31 satisfies: 0.3 mm ≤ L2 ≤ 1 mm. When the distance L2 between the cavity wall of the heating chamber 21 and the heating element 31 is within the above range, L2 is more appropriate. The cavity wall of the heating chamber 21 and the heating element 31 can rotate relative to each other to avoid wear caused by interference.

[0053] In some embodiments, the heating device includes a heat insulation member 20, and the heat insulation member 20 encloses the heating chamber 21.

[0054] In this embodiment, the heat insulation member 20 can block the heat conduction of the heating member 31 to the outside of the heating chamber 21, avoiding thermal damage to precision components such as the power supply member and the circuit board inside the main housing 40 caused by the heat generated by the heat insulation member 20, preventing heating device failures or shortened service life due to excessive temperature; and avoiding the heat generated by the heat insulation member 20 from being conducted to the main housing 40, thus reducing the risk of scalding consumers. Moreover, the heat insulation member 20 can also maintain the temperature stability inside the heating chamber 21, avoiding the influence of temperature fluctuations on the aerosol generation efficiency, and reducing energy loss by reducing the heat diffusion to the external environment. Therefore, the heat insulation member 20 is one of the important components to ensure the stable performance, safe use and consumer experience of the heating device.

[0055] As Figure 4 As shown in FIG. -9, in some embodiments, the zoned heating mechanism 30 further includes a turntable 32 and a pair of power supply terminals 33. Among them, the turntable 32 is connected to the driving member 34 and can rotate coaxially with the heating cup 10 under the drive of the driving member 34; one of the pair of power supply terminals 33 and the heating member 31 is single, and the other is multiple and arranged at intervals along the circumference of the turntable 32. Each of the other is corresponding to a heating zone 11. The one is provided on the turntable 32, and the turntable 32 drives the heating member 31 and the pair of power supply terminals 33 to rotate relative to each other, so as to selectively conduct the one on the turntable 32 and one of the other.

[0056] Exemplarily, the driving member 34 is connected to the turntable 32, and the driving member 34 drives the turntable 32 to rotate. The rotation axis of the turntable 32 is collinear with the axis of the heating cup 10.

[0057] When the heating device of this embodiment is in use, the driving member 34 drives the turntable 32 to rotate, and the turntable 32 drives the single pair of power supply terminals 33 or the single heating member 31 provided thereon to rotate, so that the single pair of power supply terminals 33 rotates relative to the multiple heating members 31, or the single heating member 31 rotates relative to the multiple pairs of power supply terminals 33, so as to selectively conduct one pair of power supply terminals 33 and one heating member 31. The conducted heating member 31 heats the facing heating zone 11, realizing the time-sharing heating of different heating zones 11 by the heating member 31.

[0058] In some embodiments, the pair of power supply terminals 33 includes a positive terminal 331 and a negative terminal 332. The positive terminal 331 is electrically connected to the positive pole of the power supply member, and the negative terminal 332 is electrically connected to the negative pole of the power supply member. When the pair of power supply terminals 33 is conducted with one heating member 31, the positive terminal 331 and the negative terminal 332 are simultaneously connected to the one heating member 31, and the current flows from the positive terminal 331 to the heating member 31 and then flows out from the negative terminal 332. The heating member 31 is turned on and generates heat when there is current, realizing the heating function.

[0059] AsFigure 4 As shown in FIGS. -6, in some embodiments, one of them is the power supply terminal pair 33, and the other is the heating element 31. That is, the heating device has a plurality of heating elements 31 and a power supply terminal pair 33. The plurality of heating elements 31 are arranged at intervals along the circumferential direction of the heating cup 10, and each heating zone 11 faces a different heating element 31 respectively; a power supply terminal pair 33 is connected to the turntable 32, and the turntable 32 is configured to drive the power supply terminal pair 33 to rotate, so that the heating elements 31 faced by different heating zones 11 are sequentially connected to different power supply terminal pairs 33.

[0060] In this embodiment, there is one power supply terminal pair 33, and the power supply terminal pair 33 is arranged on the turntable 32. There are a plurality of heating elements 31, and the plurality of heating elements 31 are arranged at intervals along the circumferential direction of the turntable 32, and each heating element 31 corresponds to a heating zone 11. When the heating device is in use, the driving member 34 drives the turntable 32 to rotate, and the turntable 32 drives the power supply terminal pair 33 to rotate, so that the heating elements 31 faced by different heating zones 11 are sequentially connected to the power supply terminal pair 33. The connected heating elements 31 generate heat, and the heating elements 31 realize time - sharing heating of different heating zones 11. Moreover, each heating element 31 is not always in the on - heat - generating state, which can also ensure the service life of each heating element 31; in addition, the heating elements 31 faced by the heating zones 11 are sequentially connected to the power supply terminal pair 33, which can avoid the problem that the same part of the aerosol - generating article 50 is repeatedly heated, resulting in charring of the base material, affecting the overall sensory experience, and decreasing the pleasure and comfort.

[0061] As Figure 7 As shown in FIGS. -9, in some embodiments, one of them is the heating element 31, and the other is the power supply terminal pair 33. That is, the heating device has a single heating element 31 and a plurality of power supply terminal pairs 33. Each pair of the plurality of power supply terminal pairs 33 corresponds to a heating zone 11; the heating element 31 is connected to the turntable 32, and the turntable 32 is configured to drive the heating element 31 to rotate to different heating zones 11 and connect to the power supply terminal pair 33 corresponding to the heating zone 11 to realize heating.

[0062] In this embodiment, there is one heating element 31, and the heating element 31 is arranged on the turntable 32. There are a plurality of power supply terminal pairs 33, and the plurality of power supply terminal pairs 33 are arranged at intervals along the circumferential direction of the turntable 32, and each power supply terminal pair 33 corresponds to a heating zone 11. When the heating device is in use, the driving member 34 drives the turntable 32 to rotate, and the turntable 32 drives the heating element 31 to rotate to face different heating zones 11, and the heating element 31 is connected to the power supply terminal pair 33 corresponding to the heating zone 11 to realize heating, that is, the heating element 31 realizes time - sharing heating of different heating zones 11.

[0063] In some embodiments, the turntable 32 is located outside the heating cup 10 and away from the side of the outlet 12, that is, located below the heating cup 10. In this way, the arrangement of the turntable 32 is convenient, and the interference between the turntable 32 and the heating cup 10 is avoided.

[0064] In some embodiments, the arc length of the heating element 31 can be limited by the degree of the central angle of the circle according to the diameter of the aerosol generating article 50, with the center point of the cross section of the aerosol generating article 50 as the center of the circle. The arc length used can be the formula: L = (n / 360) × 2πr, where L is the arc length, n is the degree of the central angle of the circle, r is the radius of the cigarette, and n is the number of heating zones 11. By setting the arc length of the heating element 31, the heating device can match all conventional aerosol generating articles 50, and can customize the baking of different areas of the aerosol generating article 50.

[0065] In some embodiments, at least two heating elements 31 have different arc lengths around the circumference of the heating cup 10. In this way, the heating device can meet the needs of consumers for time-divided and differentiated aerosol output during the inhalation process. Figure 10 As shown, there are three heating elements 31, wherein the direction of the arrow represents the heating order of each heating element 31, the arc lengths of the heating elements 31a and 31b are smaller than the arc length of the heating element 31c, and when the heating device is used, the puffing time of a single aerosol generating product 50, that is, the heating cycle of the single aerosol generating product 50 by the heating device can be divided into three sections, the first section at the beginning is heated by the heating element 31b, the second section is heated by the heating element 31c, and the third section is heated by the heating element 31a. In this way, when the same power is applied, the heating temperatures of the heating elements 31a and 31b corresponding to the first and third sections are higher and the heating is faster, so that the aerosol can be output quickly in the front section to meet the demand for the first puff to generate aerosol quickly, and the aerosol can be output stably in the middle section, and the heating temperature at this time is basically stable, and it is only necessary to ensure the continuous output of aerosol. When the smoke-generating substance in the substrate is less in the back section, the aerosol can still be continuously output, so as to ensure the effective number of puffs of the single aerosol generating product 50.

[0066] In some embodiments, the arc lengths of the multiple heating elements 31 can also be set to be the same, so that the multiple heating elements 31 divide the heating cup 10 equally, so as to achieve time-sharing heating of different heating areas 11. The preheating time of a single part of the aerosol generating product 50 is much lower than the heating time of the conventional whole aerosol generating product 50, thereby reducing the consumer's waiting time for inhalation.

[0067] It is understandable that the number of heating zones 11 can be set according to usage requirements. For example, the number of heating zones 11 is two, three, four, ten, fifteen, and multiple values ​​between the above values. Figure 3 and Figure 10As shown, there are three heating zones 11 and three heating elements 31 respectively.

[0068] In some embodiments, when the heating device is in use, the rotation of the driving member 34 can be automatic or manual. When the driving member 34 is manually rotated, a corresponding position can be set, that is, feedback is given to the consumer after the rotation is in place. This application does not go into details about this.

[0069] like Figure 2 In some embodiments, the aerosol generating product 50 includes a filtering section 51, a cooling section 52, a smoking section 53, and a sealing section 54. The filtering section 51, the cooling section 52, the smoking section 53, and the sealing section 54 are arranged in sequence. The smoking section 53 and the sealing section 54 are inserted into the heating cup 10, and the heating element 31 mainly heats the smoking section 53 to generate an aerosol.

[0070] In the heating device of the embodiment of the present application, the heating element 31 heats different heating zones 11 in different time periods, so that any heating zone 11 can be prevented from being heated continuously, thereby preventing the portion of the aerosol generating product 50 close to or in contact with the heating zone from being heated repeatedly, which causes the aerosol generating product 50 to have an obvious burnt smell in the later stage of the puff, affecting the overall sensory experience, and reducing the pleasure and comfort. The heating device realizes zoned heating through the heating element 31, and the preheating time of the portion of the aerosol generating product 50 close to or in contact with the heated heating zone is shorter, which can reduce the waiting time for consumers.

[0071] The embodiment of the present application provides an aerosol generating system, which includes an aerosol generating product 50 and a heating device as described above, and the aerosol generating product 50 is arranged in a heating cup 10 of the heating device. Since the heating device can prevent the aerosol generating product 50 from having an obvious burnt smell in the later stage of inhalation, the overall sense, pleasure and comfort of the consumer can be improved; and the waiting time of the consumer can be reduced. Therefore, the aerosol generating system can improve the user's satisfaction.

[0072] In some embodiments, the aerosol generating system further includes a switch 41 and a power supply. The switch 41 is disposed on the main housing 40, and the power supply is disposed in the main housing 40. The switch 41 controls the opening and closing of the power supply.

[0073] When a conventional aerosol generating system is used, once the heating device is turned on, an aerosol generating product 50 will continue to be heated according to a set program. In some scenarios, if a consumer is unwilling or does not have time to inhale a whole aerosol generating product 50 at one time, the heated aerosol generating product 50 will be discarded, and when the aerosol generating product 50 is used again, the aerosol generating product 50 needs to be reinserted into the heating device, resulting in waste.

[0074] In the aerosol generating system according to the embodiment of the present application, since the heating element 31 in the heating device heats different heating zones 11 at different times, the part of the aerosol generating article 50 close to or in contact with the heated heating zone is heated. Compared with the heating element 31 heating the entire aerosol generating article 50, the heated part of the aerosol generating article 50 is smaller. When the switch 41 turns off the power supply, the part of the heating element 31 that stops heating the aerosol generating article 50 can stop generating aerosol relatively quickly, meeting the requirement of "stop immediately when puffing". The unheated part of the aerosol generating article 50 can be used next time, thus achieving the purpose of saving the aerosol generating article 50.

[0075] The above uses specific examples to illustrate the present application, which is only for helping to understand the present application and is not intended to limit the present application. For those skilled in the technical field to which the present application belongs, according to the idea of the present application, several simple deductions, deformations or substitutions can also be made.
