[0036] 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 generation of toxic and harmful substances by high-temperature combustion, while being able to experience close to the taste and flavor of a cigarette.
[0037] The technical solution of heat-not-burn heating uses a thin steel sheet to etch a loop, and adheres the loop to the outer wall of a metal tube. The loop generates heat through a resistance wire and transmits the heat to the metal tube, and then heats the cigarette through the inner wall of the metal tube. With this arrangement, the heating efficiency of the metal tube is slow during the heating process, and the user needs to wait for a long time after inserting the cigarette before being able to smoke the first puff.
[0038] For this purpose, see Figures 1 to 6 The embodiment of the present application provides a heating module 10 used on an electronic smoking device 100, which comprises a heating component 20 and a heat-conducting component 40. The heating component 20 comprises a first heating unit 21 and a second heating unit 22. The heat-conducting component 40 comprises a first heat-conducting tube 42 and a second heat-conducting tube 43 arranged at intervals along a first direction. The first heat-conducting tube 42 and the second heat-conducting tube 43 jointly define an insertion channel 41 for inserting a cigarette 1. The first heating unit 21 is wound on the outer side of the first heat-conducting tube 42, and the second heating unit 22 is wound on the outer side of the second heat-conducting tube 43. The mass of the first heat-conducting tube 42 is less than the mass of the second heat-conducting tube 43.
[0039] The first heat-conducting pipe 42 and the second heat-conducting pipe 43 are arranged in the first direction, so when the user inserts the cigarette 1 into the insertion channel 41, the first heat-conducting pipe 42 can be heated by the first heating unit 21. Since the mass of the first heat-conducting pipe 42 is smaller than that of the second heat-conducting pipe 43, the heat originally used to heat the whole pipe is now used to heat only the first heat-conducting pipe 42, so the temperature rises faster and the waiting time for the first puff is shorter.
[0040] It can be understood that in the existing scheme of heating the whole pipe and the whole heating assembly, the heating assembly starts to heat the whole pipe first. During this process, the whole pipe plays a role in heat conduction and heat equalization, so the temperature of the whole pipe is roughly the same everywhere. It takes a long time to heat the whole pipe to the smoking temperature of the cigarette 1, and the efficiency is slow. Under other conditions, the mass of the first heat-conducting pipe 42 is smaller than that of the second heat-conducting pipe 43, so when the same amount of heat is used to raise the temperature, the first heat-conducting pipe 42 can be heated to a higher temperature and the temperature rises faster, so the user's waiting time for the first puff is shorter.
[0041] Further, in an embodiment, the size of the first heat-conducting pipe 42 in the first direction is smaller than that of the second heat-conducting pipe 43 in the first direction. In this way, the heating area of the first heat-conducting pipe 42 for the cigarette 1 is small, the temperature rises faster, and the user's waiting time for the first puff is shorter.
[0042] In addition, the thickness of the first heat-conducting pipe 42 and the second heat-conducting pipe 43 can be the same. In the same case, a metal whole pipe can be directly manufactured and then cut to obtain the first heat-conducting pipe 42 and the second heat-conducting pipe 43, without the need for additional mold opening, reducing production manufacturing costs. Of course, the thickness of the first heat-conducting pipe 42 and the second heat-conducting pipe 43 can also be different. In different cases, the thickness of the first heat-conducting pipe 42 can be greater than or less than that of the second heat-conducting pipe 43, etc., which is not limited here.
[0043] In an embodiment, the thickness of the first heat-conducting pipe 42 is smaller than that of the second heat-conducting pipe 43. In this way, since the first heat-conducting pipe 42 is thinner, the heat loss is smaller during heat conduction, and the temperature of the cigarette 1 rises faster.
[0044] Please refer to 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, in an embodiment, when the heating assembly 20 is used to heat the cigarette 1, the first heat-conducting pipe 42 is used to heat the first smoking section 11 of the cigarette 1, and the second heat-conducting pipe 43 is used to heat the second smoking section 12 of the cigarette 1, in this way, the first heating unit 21 and the first heat-conducting pipe 42 heat the part close to the filter, after smoking, the distance between the smoke and the filter is short, and the user can quickly inhale the smoke.
[0045] It can be understood that the shorter the length of the first heat-conducting pipe 42 is, the faster the temperature rising rate of the first smoking section 11 is, therefore, in an embodiment, the length of the first heat-conducting pipe 42 is less than 80% of the length of the second heat-conducting pipe 43, corresponding to the technical solution in the embodiment, the length of the first heat-conducting pipe 42 is less than 80% of the length of the second heat-conducting pipe 43, compared with the original whole pipe heating scheme, the waiting time of the first puff can be greatly reduced.
[0046] It should be emphasized that, since the first heat-conducting pipe 42 and the second heat-conducting pipe 43 are arranged in a spaced manner in the first direction, the heat transfer between the first heat-conducting pipe 42 and the second heat-conducting pipe 43 can be effectively reduced, so that the heat generated by the first heating unit 21 is concentrated on the first heat-conducting pipe 42, and the heat generated by the second heating unit 22 is concentrated on the second heat-conducting pipe 43.
[0047] Correspondingly, the position of the cigarette 1 located in the gap between the first heat-conducting pipe 42 and the second heat-conducting pipe 43 can only rely on the heat radiation of the first heat-conducting pipe 42 and the second heat-conducting pipe 43 for heating, therefore, the gap between the diameters of the first heat-conducting pipe 42 and the second heat-conducting pipe 43 cannot be too large, otherwise, the cigarette 1 in the gap cannot be heated well, so that the smoking material in this part cannot be well smoked, of course, the gap cannot be too small, too small, when the first heat-conducting pipe 42 is heated, a lot of heat will be transferred to the second heat-conducting pipe 43 in the form of radiation, and the heat loss is large, therefore, in an embodiment, the interval between the first heat-conducting pipe 42 and the second heat-conducting pipe 43 in the first direction is a, wherein 0.1mm≤a≤1mm, corresponding to the technical solution in the embodiment, a is greater than or equal to 0.1mm, which ensures that the heat exchange amount between the first heat-conducting pipe 42 and the second heat-conducting pipe 43 is not too large, and the heat loss is reduced, and a is less than or equal to 1mm, which ensures the heating of the smoking material in the gap.
[0048] Further, in an embodiment, the first heating unit 21 has a higher temperature rising rate than the second heating unit 22. In this way, the first heating unit 21 has a higher heat generation per unit area, and the first heat conduction pipe 42 has a smaller mass and thus needs less heat to rise in temperature, and the heat loss is small, so that the waiting time for the first puff of the user can be further reduced.
[0049] The temperature rising rate refers to the time for heating the cigarette 1 from room temperature to the smoking temperature. For example, the longer the time for heating the cigarette 1 from room temperature to the smoking temperature, the slower the temperature rising rate, and vice versa.
[0050] The first heating unit 21 and the second heating unit 22 can be arranged in series or in parallel. In the series arrangement, the two units 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 present embodiment, the first heating unit 21 and the second heating unit 22 can be independently controlled and opened or closed.
[0051] Further, in an embodiment, the first heating unit 21 and the second heating unit 22 are alternately heated. In this way, only one heating unit in the heating module 10 heats 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 the same as or similar to the heating power of the existing heating unit that heats the entire section, so that the heating power originally used for heating the entire section is now used for heating only a part, greatly improving the smoking efficiency of the cigarette 1.
[0052] Further, the heating assembly 20 has no specific implementation form and can be a heating net, a carbon fiber heating body, a printed circuit, or the like. Specifically, the carbon fiber heating body is a tubular heating body made of carbon fiber as a basic heating material and uses a reflecting surface for heat dissipation. The electric heating conversion rate is above 95%, which is 30% more energy-saving than nickel-chromium and tungsten-molybdenum materials as heating bodies. The heating assembly 20 can also be a printed circuit. The printed circuit is printed on a PI film, and the printed PI film is wound outside the heat conduction body to form the heating module.
[0053] In an embodiment, please refer to Figure 6The heating assembly 20 comprises a heating net, the first heating unit 21 comprises a first heating net, and the second heating unit 22 comprises a second heating net; wherein the first heating net comprises a plurality of first resistance wires 213 arranged at intervals, and the second heating net comprises a plurality of second resistance wires 223 arranged at intervals.
[0054] In the technical scheme of the embodiment, the first heating unit 21 is arranged as a first heating net, the second heating unit 22 is arranged as a second heating net, and each heating net comprises a plurality of resistance wires, so that the heating uniformity can be improved by arranging a plurality of resistance wires compared with a single resistance wire scheme.
[0055] In a further embodiment, the gap between the plurality of first resistance wires 213 is smaller than the gap between the plurality of second resistance wires 223, so that the density of the resistance wires of the first heating unit 21 is greater, and the corresponding temperature rising rate is also higher.
[0056] Alternatively, the cross-sectional area of the first resistance wire 213 is smaller than the cross-sectional area of the second resistance wire 223, so that the resistance value of the first resistance wire 213 is greater than the resistance value of the second resistance wire 223, so that the temperature rising rate of the first heating unit 21 is faster.
[0057] It can be understood that the first heat conduction pipe 42 and / or the second heat conduction pipe 43 can be a metal pipe or a plastic pipe, which is not limited here, and the metal pipe has the advantages of high temperature resistance and high stability. Therefore, in an embodiment, the first heat conduction pipe 42 is a metal pipe, the first heating unit 21 is wound on the outside of the first heat conduction pipe 42 and is insulatedly connected with the first heat conduction pipe 42; and / or the second heat conduction pipe 43 is a metal pipe, the second heating unit 22 is wound on the outside of the second heat conduction pipe 43 and is insulatedly connected with the second heat conduction pipe 43.
[0058] In the technical scheme of the embodiment, the first heat conduction pipe 42 and / or the second heat conduction pipe 43 are arranged as metal pipes, so that the first heat conduction pipe 42 and / or the second heat conduction pipe 43 can have the advantages of high temperature resistance and high stability.
[0059] It should be emphasized that the specific implementation form of the insulated connection is not limited, which can be to arrange an insulating layer on the outside of the heat conduction pipe, and then arrange the heating unit on the insulating layer, so as to avoid the heat conduction pipe from short-circuiting the heating unit, or to arrange an insulating layer on the heating unit, etc., which is not limited here.
[0060] Further, the heating module 10 further comprises a heat insulation film 23, the heat insulation film 23 comprises a first film segment 231 located between the heat conducting component 40 and the heat generating component 20 and a second film segment 232 located outside the heat generating component 20; wherein the first film segment 231 surrounds the outside of the heat conducting component 40 for one turn, and the second film segment 232 surrounds the outside of the heat conducting component 40 for at least three turns.
[0061] In the technical scheme of the present embodiment, the heat generating component 20 is arranged outside the heat conducting component 40, so that the heat generated by the heat generating component 20 can be transmitted to the cigarette 1 by the heat conducting component 40 to heat the cigarette 1, and the heat conducting component 40 can play a role in heat conduction and heat equalization.
[0062] By arranging the first film segment 231, the first film segment 231 can play a role in insulating between the heat generating component 20 and the heat conducting component 40, thereby avoiding the heat generating component 20 being short-circuited by the heat conducting component 40.
[0063] And the first film segment 231 surrounds the outside of the heat conducting component 40 for one turn, that is, only one layer of the heat insulation film 23 is arranged between the heat generating component 20 and the heat conducting component 40, which realizes the insulation between the heat generating component 20 and the heat conducting component 40, and at the same time, since only one layer is arranged, the influence on the heat transfer between the heat generating component and the heat conducting component 40 is small.
[0064] The second film segment 232 surrounds the outside of the heat conducting component 40 for at least three turns, so that the second film segment 232 can form at least three layers of heat insulation outside the heat generating component 20, avoid the heat generated by the heat generating component 20 from leaking out, reduce heat loss, and the second film segment 232 has at least three layers, which can make the heat insulation film 23 stand up in the width direction after being wound in multiple layers, facilitating subsequent assembly.
[0065] The heat insulation film 23 can be a PI film (polyimide film), which has good heat conductivity, insulation, adhesion, radiation resistance, and can be used for a long time in the temperature range of the heating of the smoking set.
[0066] Please refer to Figure 5 In the production process, the heat generating component 20 can be placed on the heat insulation film 23 at first, the width of the heat generating component 20 is b; the heat insulation film 23 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 winding process, the part of the heat generating component 20 and the first length edge forms the first film segment 231, and the other part forms the second film segment 232.
[0067] The electronic smoking set 100 comprises the heating module 10. The heating module 10 adopts the technical solution of the foregoing embodiment or all the technical solutions, and thus has the technical advantages of the foregoing embodiments or all the technical advantages.

The above description of the embodiments is only used to help understand the method of the present application and its core idea; meanwhile, for those skilled in the art, the specific implementation manners and application ranges can be changed according to the idea of the present application.
