[0020] The present disclosure provides a heating apparatus and a heat-not-burn smoking set, the heating apparatus is applied to the heat-not-burn smoking set, and the heating apparatus heats an aerosol-generating substrate to a temperature at which the aerosol-generating substrate generates aerosol but combustion is impossible, such that the aerosol-generating substrate generates aerosol required by a user.

[0021] Typically, to achieve more uniform heating of the aerosol-generating substrate, the heating apparatus in the heat-not-burn smoking set heats the aerosol-generating substrate circumferentially, and a heating area occupies a high area proportion on the heating apparatus, and after the heat-not-burn smoking set is started, the heating apparatus heats the aerosol-generating substrate, and excessively hot aerosol is generated due to excessive concentration of heat generated.

[0022] During high-temperature heating of the aerosol-generating substrate, aerosol generated by the aerosol-generating substrate is released from the aerosol-generating substrate through water vapor evaporated from air, and a large amount of water vapor is generated due to evaporation at an excessively high temperature, such that the generated aerosol is overheated and is not aerosol meeting temperature requirements of the user.

[0023] In the present disclosure, the heating apparatus employs a zoned heating method, two heating zones of different areas are disposed on a circumferential surface of the heating apparatus, the aerosol-generating substrate is heated in stages, and only a small amount of water vapor is evaporated each time, thereby reducing content of water vapor in the released aerosol mixed with water vapor and relatively lowering a temperature of the aerosol.

[0026] The heating apparatus 10 is installed in the inner shell 40, an insertion port 92 is disposed on the outer shell 90, and an aerosol-generating substrate 100 may be inserted into the inner shell 40 through the insertion port 92 and come into contact with the heating apparatus 10. Since the heating apparatus 10 heats the aerosol-generating substrate 100 in a circumferential heating manner, the heating apparatus 10 may have a hollow tubular structure, a needle-like structure, or a rod-like structure; when the heating apparatus 10 has the hollow tubular structure, the aerosol-generating substrate 100 may be inserted into the heating apparatus, and when the heating apparatus 10 has the needle-like structure or the rod-like structure, the heating apparatus 10 is inserted into a center of the aerosol-generating substrate 100; and in both cases, heating of the aerosol-generating substrate 100 may be achieved.

[0027] In this embodiment, the case where the aerosol-generating substrate 100 is inserted into the heating apparatus 10 is taken as an example for description. Specifically, an accommodating cavity with openings at both ends is formed in the heating apparatus 10, and the accommodating cavity communicates with the insertion port 92. In this embodiment, the insertion port 92 is coaxial with the accommodating cavity, the aerosol-generating substrate 100 may be inserted into the accommodating cavity through the insertion port 92, and the aerosol-generating substrate 100 is heated by the heating apparatus 10 to generate aerosol.

[0028] In a specific embodiment, the aerosol-generating substrate 100 may be inserted into the accommodating cavity through an opening at one end of the accommodating cavity, and air enters the accommodating cavity through an opening at the other end of the accommodating cavity. During heating of the aerosol-generating substrate 100 by the heating apparatus 10, water vapor is generated by evaporation of moisture in the air, and the water vapor takes out the aerosol generated by heating the aerosol-generating substrate 100.

[0029] In this embodiment, the aerosol-generating substrate 100 includes a substrate segment 101, a cooling segment 102, and a filter segment 103, where the substrate segment 101 is connected to one end of the cooling segment 102, and the other end of the cooling segment 102 is connected to the filter segment 103. In some embodiments, the substrate segment 101, the cooling segment 102, and the filter segment 103 are coaxially connected and wrapped by a wrapping layer. Notably, the substrate segment 101, the cooling segment 102, and the filter segment 103 wrapped by the wrapping layer may be regarded as an integrated structure. In a preferred embodiment, the aerosol-generating substrate 100 has a columnar structure. The substrate segment 101 generates aerosol through heating, the substrate segment 101 is provided with an air inlet hole, the air inlet hole communicates with the outside, and air enters the substrate segment 101 through the air inlet hole; high-temperature steam is generated in a heating state, and the aerosol is carried to the cooling segment 102 through the steam; and the cooling segment 102 is provided with a cooling cavity, the cooling cavity communicates with the filter segment 103, and the cooling cavity extends a gas passage path of the aerosol mixed with water vapor, such that the aerosol is indirectly cooled by prolonging passage time of the aerosol, and other gas impurities in the aerosol are filtered under the action of the filter segment 103.

[0030] In the above embodiment, the substrate segment 101 is accommodated in the accommodating cavity of the heating apparatus 10 and heated by the heating apparatus 10.

[0031] The power supply 50 is connected to the heating apparatus 10 through the circuit board 60, the power supply 50 provides electric energy for the heating apparatus 10, and the circuit board 60 controls an amount of heat generated by the heating apparatus 10.

[0032] In an embodiment, the power supply 50 is preferably a rechargeable battery, a charging port 93 is further disposed on the outer shell 90, and the rechargeable battery may be charged via an external mains supply, which facilitates the cyclic use and carrying of the heat-not-burn smoking set.

[0033] In this embodiment, the switch 80 is further disposed on the outer shell 90, and the switch 80 is configured to establish or release a connection between the power supply 50 and the heating apparatus 10.

[0034] In this embodiment, a reflective film 41 is further disposed in the inner shell 40, and during heating of the aerosol-generating substrate 100 by the heating apparatus 10, the reflective film 41 reflects thermal radiation generated by the heating apparatus 10 to prevent conduction of excessive heat to the outer shell 90 through the inner shell 40, thereby preventing the inconvenience of handling the heat-not-burn smoking set caused by overheating of the outer shell 90.

[0035] The air enters the accommodating cavity through a bottom port of the heating apparatus 10, the heat exchange structure 20 is disposed below the bottom port of the heating apparatus 10, the heat exchange structure 20 performs heat exchange with the heating apparatus 10 to heat incoming air, and the cooperation between the heat exchange structure 20 and the heating apparatus 10 enables to reduce energy generated by the heating apparatus 10.

[0036] The flow diverter 30 is further disposed between the heating apparatus 10 and the heat exchange structure 20, and the flow diverter 30 guides the air heated by the heat exchange structure 20 to the aerosol-generating substrate 100.

[0037] The communication assembly 70 is further disposed below the heat exchange structure 20, and the communication assembly 70 includes: a middle communication member 71, a top communication member 72, and a bottom communication member 73, where the middle communication member 71 is connected between the top communication member 72 and the bottom communication member 73, a communication channel 721 is disposed in the top communication member 72, and the communication channel 721 communicates with the heat exchange structure 20; and the middle communication member 71 is provided with an air inlet 711 and an air outlet 712, the air outlet 712 communicates with the communication channel 721, an air intake channel 731 is disposed in the bottom communication member 73, a filter element 732 is disposed in the air intake channel 731, and a communication port 74 is disposed at a bottom of the air intake channel 731.

[0038] In practical application, after the aerosol-generating substrate 100 is inserted into the accommodating cavity of the heating apparatus 10 through the insertion port 92, the air enters the air intake channel 731 through the communication port 74 by inhaling the aerosol-generating substrate 100, the filter element 732 filters impurities from the incoming air, and the air with impurities removed by filtering enters the aerosol-generating substrate 100 through the air inlet 711, the air outlet 712, and the communication channel 721; additionally, a connection between the power supply 50 and the heating apparatus 10 is established through the switch 80, and a temperature of heat generated by the heating apparatus 10 is controlled through the circuit board 60, thereby heating the aerosol-generating substrate 100; and moisture in the air evaporates to form water vapor in a high-temperature environment, the aerosol-generating substrate 100 generates aerosol particles, and the aerosol particles are taken out through the water vapor to form aerosol.

[0039] With reference to FIGS. 3 and 4, the heating apparatus 10 provided in this embodiment includes: a heat conducting carrier 11, a first heating component 12, and a second heating component 13.

[0040] As shown in FIG. 4, the heat conducting carrier 11 is provided with a first heating zone 111 and a second heating zone 112 along a circumferential direction thereof, and in FIG. 4, positions of the first heating zone 111 and the second heating zone 112 are roughly outlined by dashed boxes. The first heating component 12 is disposed in the first heating zone 111, and the second heating component 13 is disposed in the second heating zone 112.

[0041] It should be noted that the first heating component 12 is disposed in the entire first heating zone 111, the second heating component 13 is disposed in the entire second heating zone 112, and both the first heating component 12 and the second heating component 13 generate heat under the action of electric energy. Specifically, the first heating component 12 and the second heating component 13 are connected to the power supply 50 through the circuit board 60, the power supply 50 provides electric energy for the first heating component 12 and the second heating component 13, and the circuit board 60 controls heat generated by the first heating component 12 and the second heating component 13.

[0042] The first heating component 12 and the second heating component 13 perform heating asynchronously or synchronously, and in other words, when the first heating component 12 is heating, the second heating component 13 is not heating, or when the first heating component 12 is heating, the second heating component 13 is heating together with the first heating component 12. A heat output of the first heating component 12 is less than or equal to a heat output of the second heating component 13. The heat conducting carrier 11 conducts the heat generated by the first heating component 12 and / or the second heating component 13 to the substrate segment 101 of the aerosol-generating substrate 100 to heat the substrate segment 101 so as to generate aerosol.

[0043] In this embodiment, the first heating component 12 and the second heating component 13 are made of a same material with identical resistivity, the first heating component 12 occupies the entire first heating zone 111, and the second heating component 13 occupies the entire second heating zone 112; and since a ratio of an area of the first heating zone 111 to an area of the second heating zone 112 ranges from 1 / 1 to 3 / 7, the heat output of the first heating component 12 is less than or equal to the heat output of the second heating component 13.

[0044] In practical application, the first heating component 12 preheats the aerosol-generating substrate 100, and then the first heating component 12 and the second heating component 13 synchronously heat the aerosol-generating substrate 100. Since the heat output of the first heating component 12 is less than or equal to the heat output of the second heating component 13, part of water molecules may be evaporated into water vapor during the preheating process, and compared with a conventional method of heating the entire substrate segment 101 in a circumferential direction, the present disclosure reduces water vapor content relatively, thereby lowering a temperature of the aerosol. Subsequently, the second heating component 13 and the first heating component 12 perform synchronous heating, and the first heating component 12 plays an auxiliary heating role and heats together with the second heating component 13 to evaporate the remaining water molecules into water vapor, which, similarly, reduces water vapor content relatively, thereby lowering a temperature of the aerosol.

[0045] As mentioned above, the heat conducting carrier 11 may have a hollow tubular structure, a needle-like structure, or a rod-like structure; when the heat conducting carrier 11 has the hollow tubular structure, the aerosol-generating substrate 100 may be inserted into the heat conducting carrier 11, and when the heat conducting carrier 11 has the needle-like structure or the rod-like structure, the heat conducting carrier 11 is inserted into a center of the aerosol-generating substrate 100; and in both cases, circumferential heating of the aerosol-generating substrate 100 may be achieved.

[0046] In this embodiment, the case where the heat conducting carrier 11 has a hollow tubular structure is taken as an example for description. The heat conducting carrier 11 has a hollow accommodating chamber 113 with openings at both ends, and the hollow accommodating chamber 113 is an accommodating cavity; for convenience of description, the openings at both ends of the heat conducting carrier 11 are respectively defined as a first opening 114 and a second opening 115, where the first opening 114 communicates with the insertion port 92 on the outer shell 90, and the second opening 115 communicates with the communication channel 721 of the top communication member 72; and thus, the aerosol-generating substrate 100 may be inserted into the hollow accommodating chamber 113 from the first opening 114 through the insertion port 92, and the hollow accommodating chamber 113 is configured to accommodate the aerosol-generating substrate 100. More specifically, the substrate segment 101 of the aerosol-generating substrate 100 is inserted into the hollow accommodating chamber 113.

[0047] In this embodiment, the aerosol-generating substrate 100 has a columnar structure, so the hollow accommodating chamber 113 is a columnar hollow cavity adapted to the columnar aerosol-generating substrate 100, that is, the substrate segment 101 is inserted into the hollow accommodating chamber 113, and the insertion port 92 is kept coaxial with the columnar hollow cavity.

[0048] During heating, the first heating component 12 preheats the substrate segment 101 of the aerosol-generating substrate 100 inserted into the hollow accommodating chamber 113 for a period of time, and then the first heating component 12 and the second heating component 13 capable of synchronous heating perform synchronous heating of the substrate segment 101 of the aerosol-generating substrate 100 inserted into the hollow accommodating chamber 113.

[0049] In actual use, the aerosol-generating substrate 100 is inserted into the hollow accommodating chamber 113 through the insertion port 92 and the first opening 114, such that the substrate segment 101 is located in the hollow accommodating chamber 113, and the first heating component 12 performs preheating for a period of time, for example, the first heating component 12 performs preheating for 5 minutes; and in this case, part of moisture is evaporated into water vapor, and compared with the conventional heating method, the present disclosure reduces water vapor content effectively, thereby lowering a temperature of the aerosol. After the first heating component 12 preheats for a period of time, the second heating component 13 and the first heating component 12 perform synchronous heating, and the first heating component 12 plays an auxiliary heating role and heats together with the second heating component 13 to evaporate the remaining moisture into water vapor, which reduces water vapor content relatively, thereby lowering a temperature of the aerosol.

[0050] It can be understood that in this embodiment, the heat conducting carrier 11 may be regarded as a hollow tubular structure with a hollow channel, where the hollow accommodating chamber 113 is formed in the hollow channel, and two channel openings of the hollow channel are respectively formed as the first opening 114 and the second opening 115; and a ratio of an area of the first heating zone 111 occupied on a circumferential surface of the heat conducting carrier 11 to an area of the second heating zone 112 occupied on the circumferential surface of the heat conducting carrier 11 ranges from 1 / 1 to 3 / 7, such that the heat output of the first heating component 12 is less than or equal to the heat output of the second heating component 13.

[0051] Furthermore, it can be considered that a ratio of the heat output of the first heating component 12 to the heat output of the second heating component 13 ranges from 1 / 1 to 3 / 7.

[0052] During the heating of the substrate segment 101 by the first heating component 12, a steam output roughly accounts for 1 / 2 or 3 / 7 of a total steam output, and when the second heating component 13 and the first heating component 12 perform synchronous heating, roughly 1 / 2 or 4 / 7 of the total steam output is generated, that is, two steam outputs are identical or different, thereby achieving stepped heating; and steam will release heat after coming into contact with the air, and since the steam output is reduced compared with that generated by the conventional heating method, released heat is reduced, that is, the temperature of the aerosol is relatively lowered.

[0053] In an embodiment of the present disclosure, the first heating component 12 and the second heating component 13 are not made of materials with identical resistivity, and it is only necessary to ensure that heating power of the first heating component 12 is less than or equal to heating power of the second heating component 13, or the heat output of the first heating component 12 is less than or equal to the heat output of the second heating component 13.

[0054] In an embodiment, the heat conducting carrier 11 has a tubular structure, and the first heating zone 111 and the second heating zone 112 may be disposed on an inner wall or an outer wall of the heat conducting carrier 11, or in any area between the inner wall and the outer wall thereof.

[0055] When the first heating zone 111 and the second heating zone 112 are disposed on the inner wall or the outer wall of the heat conducting carrier 11, the first heating component 12 of the first heating zone 111 and the second heating component 13 of the second heating zone 112 may be insulated, and for example, an insulating tube is sleeved or an insulating material is coated. The tubular heat conducting carrier 11 may have a double-layer structure, such that the first heating zone 111 and the second heating zone 112 may be disposed between the double-layer structure of the heat conducting carrier 11, that is, between the inner wall and the outer wall of the heat conducting carrier 11. It can be understood that the double-layer structure may be configured as a double-layer insulating structure to achieve insulation treatment of the first heating component 12 and the second heating component 13.

[0056] With further reference to FIGS. 3 and 4, the first heating component 12 is provided with a first electrode 120, the second heating component 13 is provided with a second electrode 130, a common electrode 140 is further disposed between the first heating component 12 and the second heating component 13, the first electrode 120 and the second electrode 130 are configured to connect a first pole of an external power supply, the common electrode 140 is configured to connect a second pole of the external power supply, and the first heating component 12 and the second heating component 13 are connected in parallel through the common electrode 140.

[0057] It should be noted that the external power supply is the power supply 50, the power supply 50 provides electric energy for the first heating component 12 and the second heating component 13, the first pole of the power supply is a positive pole or a negative pole of the power supply, and the second pole of the power supply is the negative pole or the positive pole of the power supply.

[0058] In this embodiment, the first electrode 120 is further provided with a first lead 121, the second electrode 130 is further provided with a second lead 131, the common electrode 140 is further provided with a common lead 141, the first lead 121 and the second lead 131 are connected to the positive pole or the negative pole of the external power supply, and the common lead 141 is connected to the negative pole or the positive pole of the power supply, such that the first heating component 12 and the second heating component 13 are connected to the power supply.

[0059] In the present disclosure, the first heating component 12 is a first heating resistance sheet disposed in the first heating zone 111, and the second heating component 13 is a second heating resistance sheet disposed in the second heating zone 112; and alternatively, the first heating component 12 is a first heating resistance coating printed on the first heating zone 111, and the second heating component 13 is a second heating resistance coating printed on the second heating zone 112, specifically depending on actual needs.

[0060] As mentioned above, the first heating component 12 and the second heating component 13 are connected to the power supply 50 in parallel, and a resistance of the first heating component 12 is greater than or equal to a resistance of the second heating component 13; and according to p=U 2< / R, a larger resistance indicates smaller heating power under conditions of a same voltage, so the heating power of the first heating component 12 is less than or equal to the heating power of the second heating component 13.

[0061] As shown in FIGS. 3 and 4, the first heating component 12 is disposed in the first heating zone 111 in a bent manner, and the second heating component 13 is disposed in the second heating zone 112 in a bent manner, such that the first heating component 12 covers the first heating zone 111 and the second heating component 13 covers the second heating zone 112.

[0062] In summary, in the heating apparatus and the heat-not-burn smoking set disposed in this embodiment, the substrate segment is preheated by the first heating component to evaporate part of moisture into water vapor, and compared with a conventional method for heating an aerosol-generating substrate through a heating apparatus with a high proportion of area disposed on a circumferential surface of a heating tube, the present disclosure effectively reduces content of water vapor, thereby lowering a temperature of the aerosol. After the first heating component preheats, the second heating component and the first heating component perform synchronous heating, and in this case, the first heating component plays an auxiliary heating role and heats together with the second heating component to evaporate the remaining moisture into water vapor, which reduces water vapor content relatively, thereby lowering a temperature of the aerosol.
