Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0042] Heat-not-burn is a technology that uses a special heating device to heat a special "cartridge" or "cigarette" to a low temperature to release smoke, avoiding the production of toxic and harmful substances by high-temperature combustion, while being able to experience close to the taste and flavor of a cigarette.

[0043] The technical solution of heat-not-burn heating is to form a loop on a thin steel sheet by etching, and adhere the loop to the outer wall of a metal tube, heat the metal tube through a resistance wire, and then heat the cigarette through the inner wall of the metal tube. However, in this technical solution, the entire cigarette is heated, the heating rate is slow, and in this process, if the cigarette needs to be raised to the smoking temperature, the user will have to wait for a long time.

[0044] Please refer to Figures 2 to 8 To this end, the embodiment of the present application provides a heating module 10, which comprises a heating assembly 20, the heating assembly 20 comprises a first heating unit 21 and a second heating unit 22 arranged in sequence along a first direction, wherein the first heating unit 21 is used for heating a first smoking section 11 of a cigarette 1, the second heating unit 22 is used for heating a second smoking section 12 of the cigarette 1, and the coverage area of the first heating unit 21 is smaller than that of the second heating unit 22; wherein the rated heating power of the heating assembly 20 is a, and the rated heating of the first heating unit 21 is b, wherein b≥0.5a.

[0045] It should be noted that the first heating unit 21 and the second heating unit 22 are arranged in sequence in the first direction, which can be arranged in close proximity in the first direction, or can be arranged in a spaced manner, which is not limited herein. The specific implementation form of the first heating unit 21 and / or the second heating unit 22 is not limited, which can be in the form of a heating net, a printed circuit, a carbon fiber heating body, etc., which is not limited herein.

[0046] It is emphasized that b≥0.5a, b can be any value between 0.5a-a, such as 0.5a, 1a, 0.6a, etc., which is not limited here, and the specific value of the second heating unit 22 is not limited, the rated heating power of the second heating unit 22 is c, when the second heating unit 22 and the first heating unit 21 can heat at the same time, the rated heating power c of the second heating unit 22 and the rated heating power b of the first heating unit 21, the sum of the two is a, that is, the value of c is between 0-0.5a, of course, the first heating unit 21 and the second heating unit 22 can be alternately heated, at this time, the rated heating power c of the second heating unit 22 can be taken between 0-a, in summary, the value of b is 0.5a-a, the value of c is 0-a, and the relationship between b and c can be b greater than c, b less than c, b equal to c, etc., which is not limited here, the heating rate of the first heating unit 21 and the second heating unit 22 can be the same or different, at different times, the first heating unit 21 can be less than the second heating unit 22, or greater than the second heating unit 22, etc., which is not limited here. The coverage area of the first heating unit 21 refers to the coverage area of the first heating unit 21 on the cigarette 1, and the coverage area of the second heating unit 22 refers to the coverage area of the second heating unit 22 on the cigarette 1. The value range of a is not limited and can be consistent with the heating power of the existing electronic smoking set 100. Specifically, the value range of a is 3-200w, which is not limited here.

[0047] Specifically, the initial resistance of the heating unit needs to be as small as possible under the premise of safety, for example, when using a common 18650 series battery, the resistance can be configured to be between 0.4Ω-1Ω.

[0048] Please see Figure 1 , the cigarette 1 is divided into a smoking section, a cooling section and a filter section, the smoking section includes a first smoking section 11 close to the filter section and a second smoking section 12, the first heating unit 21 is used to heat the first smoking section 11 of the cigarette 1, and the second heating unit 22 is used to heat the second smoking section 12 of the cigarette 1. By setting this way, the first heating unit 21 heats the first smoking section 11, and the generated smoke is close to the distance of the cigarette holder, which can make the user quickly smoke.

[0049] The first heating unit 21 and the second heating unit 22 are arranged in sequence along the first direction, the coverage area of the first heating unit 21 is smaller than that of the second heating unit 22, and the rated heating power of the first heating unit 21 is greater than or equal to half of the total heating power of the heating assembly 20. Therefore, at least half of the heat can be used to heat the first smoking section 11 with a smaller area during actual use, thereby improving the heating efficiency of the first smoking section 11 and reducing the user's smoking waiting time.

[0050] Further, in an embodiment, the heating power of the first heating unit 21 and the second heating unit 22 is the same. In this embodiment, by designing the heating power of the first heating unit 21 and the second heating unit 22 to be the same, the coverage area of the first heating unit 21 and the second heating unit 22 can be adjusted directly during actual design, thereby adjusting the heating rate of the first heating unit 21 and the second heating unit 22, and reducing the design difficulty of the designer.

[0051] Specifically, the heating power of the first heating unit 21 and the second heating unit 22 is the same. In an embodiment in which the first heating unit 21 and the second heating unit 22 heat at the same time, the first heating unit 21 and the second heating unit 22 can both be 0.5a. At this time, the first heating unit 21 and the second heating unit 22 together constitute the rated heating power of the heating assembly 20.

[0052] Of course, the rated heating power of the first heating unit 21 and / or the second heating unit 22 can also be equal to a. At this time, the first heating unit 21 and the second heating unit 22 heat alternately and can both reach the rated power of the heating assembly 20. At this time, the heating rate of the first heating unit 21 is the fastest. The power originally used to heat the entire cigarette 1 is now used to heat only half or less of the cigarette 1, greatly improving the heating efficiency of the cigarette 1. When the user inserts the cigarette 1 into the insertion channel 41 of the electronic smoking set 100, the first heating unit 21 can be used to heat first, allowing the first smoking section 11 to heat quickly and shorten the user's waiting time for the first puff. Of course, the first heating unit 21 can also be used to heat after detecting that the user has completed a puff, to quickly generate a portion of smoke for the user's next puff and reduce the interval between two puffs.

[0053] Further, in an embodiment, the first heating unit 21 has a coverage area less than half of the coverage area of the second heating unit 22, corresponding to the time when the coverage area of the first heating unit 21 is much smaller than the coverage area of the second heating unit 22, and thus the heating of the cigarette 1 by the first heating unit 21 can be more concentrated, and the smoking efficiency of the first smoking section 11 is higher.

[0054] Specifically, please refer to Figure 7 In an embodiment, the heating module 10 further comprises a heat conduction pipe 40, the first heating unit 21 comprises a first resistance wire 213, and the first resistance wire 213 is arranged on the outer side of the heat conduction pipe 40 in the circumferential direction of the heat conduction pipe 40. In the embodiment, the first heating unit 21 is composed of the first resistance wire 213, and the first resistance wire 213 is arranged on the outer side of the heat conduction pipe 40 in the circumferential direction of the heat conduction pipe 40. At this time, the size of the first heating unit 21 in the axial direction of the cigarette 1 can be controlled within 20% of the smoking section, so that the first smoking section 11 corresponds to the amount of smoke generated by one puff. In actual use, the first smoking section 11 can be heated by the first heating unit 21 to generate the first puff. At this time, the first puff is generated at the fastest rate, and in the subsequent smoking stage, the first heating unit 21 does not heat, and the second heating unit 22 heats, thereby avoiding dry burning and quickly generating the first puff.

[0055] In addition, the second heating unit 22 comprises a plurality of second resistance wires 223 arranged in parallel, and the second resistance wires 223 are arranged in a back-and-forth bending manner in the circumferential direction of the heat conduction pipe 40. In the embodiment, the second heating unit 22 comprises a plurality of second resistance wires 223 arranged in parallel, which can improve the uniformity of heating of the second heating unit 22. Compared with the single resistance wire scheme, the plurality of second resistance wires 223 can make the coverage area of the second heating unit 22 larger, and in particular, the second resistance wires 223 are arranged in a back-and-forth bending manner in the circumferential direction of the heat conduction pipe 40, which can further increase the coverage area of the second heating unit 22 and heat more parts of the cigarette 1.

[0056] The first heating unit 21 and the second heating unit 22 can be arranged in series or in parallel. When arranged in series, both must be opened or closed at the same time. In a further embodiment, the first heating unit 21 and the second heating unit 22 are arranged in parallel. In the technical solution of the present embodiment, the first heating unit 21 and the second heating unit 22 are arranged in parallel, so that they can be controlled independently of each other, and each can be independently turned on and off.

[0057] Further, in an embodiment, the first heating unit 21 and the second heating unit 22 alternately generate heat. In this way, only one heating unit in the heating module 10 generates heat at a time, so that the power supply of the electronic smoking set 100 only needs to supply power to one of the first heating unit 21 and the second heating unit 22 during heating. Correspondingly, the heating power of the first heating unit 21 and the second heating unit 22 can be made consistent with or almost the same as the heating power of the existing whole-section heating heating unit, so that the original heating power for heating the whole section is now used to heat only a part, greatly improving the smoking efficiency of the cigarette 1.

[0058] In addition, in some embodiments, the heating module 10 further includes a heat conduction pipe 40, the heat conduction pipe 40 includes a first heat conduction portion 42 and a second heat conduction portion 43 arranged in a first direction, the first heating unit 21 is wound around the first heat conduction portion 42, and the second heating unit 22 is wound around the second heat conduction portion 43; wherein the size of the first heat conduction portion 42 in the first direction is smaller than the size of the second heat conduction portion 43 in the first direction. In the technical solution of the present embodiment, the heat conduction pipe 40 is arranged as the first heat conduction portion 42 and the second heat conduction portion 43 arranged in the first direction. When the user inserts the cigarette 1 into the insertion channel 41, the first heat conduction portion 42 can be heated by the first heating unit 21. Therefore, the heat originally used to heat the whole pipe is now used to heat only the first heat conduction portion 42. Therefore, the heating rate is faster, and the waiting time for the first puff is shorter.

[0059] It can be understood that in the prior scheme of heating by using the whole pipe and the whole heating assembly, the heating assembly starts to heat, and first the whole pipe is heated. In this process, the whole pipe plays a role of heat conduction and heat equalization, so the temperature of each part of the whole pipe is roughly the same. It takes a long time to heat the whole pipe to the smoking temperature of the cigarette 1, and the efficiency is slow. Under the same other conditions, the mass of the first heat conduction part 42 is less than that of the second heat conduction part 43. When the same heat is used for heating, the first heat conduction part 42 can be heated to a higher temperature, and the heating rate of the first heat conduction part 42 is faster, so that the waiting time for the first puff of the user is shorter.

[0060] Further, in an embodiment, the size of the first heat conduction part 42 in the first direction is smaller than the size of the second heat conduction part 43 in the first direction. In this way, the heating area of the first heat conduction part 42 to the cigarette 1 is small, the heating rate is faster, and the waiting time for the first puff of the user is shorter.

[0061] The specific implementation form of the heating assembly 20 is not limited, which can be a heating net, a carbon fiber heating body, a printed circuit, etc. Specifically, the carbon fiber heating body is a tubular heating body made of carbon fiber as the basic heating material. The heat is dissipated by using a reflecting surface, and the electric heating conversion rate is above 95%. Compared with nickel-chromium and tungsten-molybdenum materials as the heating body, the energy saving is 30%. When the isolation member 23 is a PI film, the heating assembly 20 can also be a printed circuit, so as to print the printed circuit on the PI film. After printing, the PI film is wound to the outside of the heat conduction body, and the heating module is formed.

[0062] Further, the heating assembly 20 is a heating net, and the heating module 10 further comprises an isolation member 23. The isolation member 23 is at least sleeved on the outside of the heating assembly 20, and tpi glue is coated on the isolation member 23. The heating net is adhered to the isolation member 23 by the tpi glue.

[0063] The tpi glue has thermoplasticity and good insulation performance, and the adhesive form can tightly combine the heat conduction pipe 40, the heating assembly 20 and the isolation member 23 together, effectively avoiding the generation of bubbles, and avoiding the influence of the stability of the heating module 10 caused by the expansion of the bubbles under heating.

[0064] Specifically, taking the heating assembly 20 as a heating net as an example, in the assembly process, the heating net can be placed on the isolation member 23 first, and then the part of the heating assembly 20 is hot-pressed, and then it is wound to the heat conduction pipe 40, so as to complete the assembly process of the heating module 10. In this process, the tpi glue can tightly combine the heat conduction pipe 40, the heating assembly 20 and the isolation member 23 together.

[0065] In addition, the heating module 10 further comprises a heat-conducting pipe 40 having an insertion channel 41 adapted to insert the cigarette 1; the heating assembly 20 is arranged outside the heat-conducting pipe 40; the isolation piece 23 comprises a heat-insulating and insulating film, which comprises a first film segment 231 between the heat-conducting pipe 40 and the heating assembly 20 and a second film segment 232 outside the heating assembly 20; wherein the first film segment 231 surrounds the outside of the heat-conducting pipe 40 for one turn, and the second film segment 232 surrounds the outside of the heat-conducting pipe 40 for at least three turns.

[0066] In the technical scheme of the present embodiment, the heating assembly 20 is arranged outside the heat-conducting pipe 40, so that the heat emitted by the heating assembly 20 can be transmitted to the cigarette 1 by the heat-conducting pipe 40 to heat the cigarette 1, and the heat-conducting pipe 40 can play a role in heat conduction and heat equalization.

[0067] It can be understood that the heat-conducting pipe 40 can be a metal pipe or a plastic pipe, which is not limited here. When the heat-conducting pipe 40 is a metal pipe, the first film segment 231 can play a role in insulation between the heating assembly 20 and the heat-conducting pipe 40, thereby avoiding short circuit of the heating assembly 20 by the heat-conducting pipe 40.

[0068] The first film segment 231 surrounds the outside of the heat-conducting pipe 40 for one turn, that is, only one layer of heat-insulating and insulating film is arranged between the heating assembly 20 and the heat-conducting pipe 40, which can realize insulation between the heating assembly 20 and the heat-conducting pipe 40 while having less influence on heat transfer between the heating assembly and the heat-conducting pipe 40 due to only one layer.

[0069] The second film segment 232 surrounds the outside of the heat-conducting pipe 40 for at least three turns, so that the second film segment 232 can form at least three layers of heat insulation outside the heating assembly 20 to avoid heat leakage of the heating assembly 20 and reduce heat loss, and the second film segment 232 has at least three layers, which can make the heat-insulating and insulating film stand up in the width direction after being wound in multiple layers, facilitating subsequent assembly.

[0070] The heat-insulating and insulating film can be a PI film (polyimide film) which has good heat conductivity, insulation, adhesion, and radiation resistance and can be used for a long time in the temperature range of heating by the smoking set.

[0071] Please refer to Figure 8In the production process, the heat generating component 20 can be placed on the heat insulation film at a position, the width of the heat generating component 20 is b; the heat insulation film has a first length edge in the length direction; the distance between the heat generating component 20 and the first length edge is a; wherein a > b, in the rolling process, the heat generating component 20 and part of the first length edge form the first film section 231, and other parts form the second film section 232.

[0072] The electronic smoking set 100 provided by the embodiment of the present application also adopts the technical solution of the heating module 10 provided by the embodiment of the present application, and thus has the technical advantages of the heating module 10 provided by the embodiment of the present application.

[0073] The heating module and the electronic smoking set provided by the embodiment of the present application are described in detail above, and the principle and implementation manner of the present application are described by using specific examples; the above description of the embodiments is only used to help understand the method of the present application and the core idea thereof; meanwhile, for those skilled in the art, the specific implementation manner and application range can be changed according to the idea of the present application; in conclusion, the content of the description should not be understood as a limitation of the present application.
