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.
[0040] Heat-not-burn is a technology that uses a special heating device to heat a special "cartridge" or "cigarette" to a low temperature to generate 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.
[0041] At present, the heating module of the heat-not-burn is generally wrapped with an isolation film on the outside of the heat-conducting member, and then wrapped with a heating assembly, and then wrapped with an isolation film. In this arrangement, there is a certain gap between the heating assembly and the isolation film, resulting in large heat loss and poor stability.
[0042] For this purpose, refer to Figures 1 to 6 The heating module 10 provided by the embodiment of the present application comprises a heat-conducting member 40, a heating assembly 20, and an isolation film 23. The heat-conducting member 40 is formed with an insertion channel 41 for inserting a cigarette 1. The heating assembly 20 is arranged on the outside of the heat-conducting member 40 and used for heating the insertion channel 41. The isolation film 23 has a front side and a back side arranged oppositely in the thickness direction thereof. The isolation film 23 has an insulating portion 231, a bearing portion 233, and a heat-insulating portion 232 arranged sequentially in the length direction thereof. The front side of at least the insulating portion 231 and the bearing portion 233 is coated with an insulating glue 234. The front side of the insulating portion 231 is adhered to the outside of the heat-conducting member 40 through the insulating glue 234. The heating assembly 20 is adhered to the front side of the bearing portion 233 through the insulating glue 234. The front side of the bearing portion 233 is wound on the back side of the insulating portion 231.
[0043] It should be noted that the specific implementation form of the heat-conducting member 40 is not limited, which can be in the form of a metal pipe or a plastic pipe, and is not limited herein. When the heat-conducting member 40 is made of a conductive material, the isolation member can also be located between the heating assembly 20 and the heat-conducting member 40 to avoid short circuiting of the heating assembly 20 by the heat-conducting member 40. The specific implementation form of the isolation member is not limited, as long as it has superior insulation and heat insulation performance. It can be a PI film (polyimide film) which has good thermal conductivity, insulation, adhesion, and radiation resistance, and can be used for a long time in the temperature range of the heating of the smoking set. It can also be an aerogel member, and the like, which is not limited herein. The specific implementation form of the heating assembly 20 is not limited, which can be in the form of a printed circuit, a carbon fiber heating body, a heating net, and the like, which is not limited herein. The isolation film 23 can be a PI film (polyimide film) which has good thermal conductivity, insulation, adhesion, and radiation resistance, and can be used for a long time in the temperature range of the heating of the smoking set.
[0044] It can be understood that the positive side of the insulation part 231 is adhered to the outer side of the heat conduction piece 40 through the insulating glue 234, so that the isolation film 23 and the heating assembly 20 can be adhered to the outer side of the heat conduction piece 40, and the adhesion is better than other connection modes such as pasting, clamping, riveting and the like, and gaps and bubbles are not easy to be generated, and the insulation part 231 can also play a role of isolating the heating assembly 20 and the heat conduction piece 40, avoiding the short circuit phenomenon of the heating assembly 20 caused by the connection of the heat conduction piece 40. The heating assembly 20 is adhered to the positive side of the bearing part 233 through the insulating glue 234. Specifically, in the production process, the insulating glue 234 can be coated on the positive side of the bearing part 233 first, then the heating assembly 20 is placed on the positive side of the bearing part 233, and then the heating assembly 20 is hot-pressed to be integrated with the bearing part 233. At this time, in the process of rolling the isolation film 23 to the outer side of the heat conduction piece 40, the heating assembly 20 can also be rolled to the outer side of the heat conduction piece 40, and then the bearing part 233 is rolled, and then the heat insulation part 232 can be continuously rolled on the outer side of the bearing part 233, so that the heat insulation part 232 plays a role of heat insulation of the heating assembly 20, blocks the heat of the heating assembly 20 from diffusing to the outside of the heat conduction piece 40, and reduces the heat loss.
[0045] In the embodiment, the insulating glue 234 is coated on the positive side of the insulation part 231 and the bearing part 233, the positive side of the insulation part 231 is adhered to the outer side of the heat conduction piece 40 through the insulating glue 234, and the heating assembly 20 is adhered to the positive side of the bearing part 233 through the insulating glue 234, so that the insulating glue 234 can tightly combine the isolation film 23, the heating assembly 20 and the heat conduction piece 40 together, reduce the gap, thereby reducing the heat loss, and due to the reduction of the gap, the bubbles between the three will also be reduced, avoiding the case that the bubbles are heated to expand and affect the stability of the heating module 10.
[0046] Further, the positive side of the isolation film 23 can be coated with the insulating glue 234 only at the insulation part 231 and the bearing part 233, or can be coated with the insulating glue 234 on the positive side of the isolation film 23, which is not limited here, please refer to Figures 7 to 10In an embodiment, the insulation film 23 is coated with the insulating glue 234 on both sides, and in this embodiment, the insulation part 232 is also coated with the insulating glue 234 on both sides, so that after the insulation film 23 is rolled, the insulation part 232 and the back side of the bearing part 233 can be combined more tightly, avoiding the generation of bubbles between the insulation part 232 and the bearing part 233.
[0047] It should be noted that the insulating part 231 plays a role of insulation between the heat-conducting member 40 and the heat-generating component 20, and if the thickness of the insulating part 231 is too thick, it will inevitably affect the heat transfer effect between the heat-generating component 20 and the heat-conducting member 40, and the sealing part plays a role of heat insulation and heat resistance, and its thickness cannot be too thin, otherwise, the effect of heat insulation and heat resistance is not good.
[0048] Therefore, please refer to Figure 8 and Figure 10 In an embodiment, the overall thickness of the insulating part 231 is less than the overall thickness of the insulation part 232, and in this way, the overall thickness of the insulating part 231 is small, which weakens its influence on the heat transfer between the heat-generating component 20 and the heat-conducting member 40, and the overall thickness of the insulation part 232 is large, which enhances the heat insulation and heat resistance effect of the heat-generating component 20, blocks the heat emitted by the heat-generating component 20 from being transferred to the outside of the insertion channel 41, and improves the heating efficiency of the heating module 10.
[0049] Specifically, the specific implementation form of the overall thickness of the insulating part 231 being less than the overall thickness of the insulation part 232 is not limited, which can be that the coating thickness of the insulating glue 234 on the insulating part 231 is less than the coating thickness on the insulation part 232, that is, the thickness of the glue layer on the insulating part 231 is less than the thickness of the glue layer on the insulation part 232, so that the overall thickness of the insulating part 231 is less than the overall thickness of the insulation part 232. It can also be that the thickness of the insulation film 23 at the insulating part 231 is less than the thickness at the insulation part 232, that is, the insulation film 23 is thinned at the insulating part 231, so that the overall thickness of the insulating part 231 is less than the overall thickness of the insulation part 232. Of course, the insulating part 231 can also be coated with the insulating glue 234 on one side, and the insulation part 232 can be coated with the insulating glue 234 on both sides, that is, only one side of the insulating part 231 is coated with the insulating glue 234, and both sides of the insulation part 232 are coated with the insulating glue 234, and in this way, the distance between the heat-conducting member 40 and the heat-generating component 20 can be effectively reduced, the heat transfer effect of the two is better, and the like, which is not limited here.
[0050] It is emphasized that in actual use, the coating thickness of the insulating glue 234 on the insulation part 231 is less than that on the heat insulation part 232; the thickness of the isolation film 23 at the insulation part 231 is less than that at the heat insulation part 232; the front side of the insulation part 231 is coated with the insulating glue 234, and the front side and the back side of the heat insulation part 232 are both coated with the insulating glue 234; the three technical solutions can be set alternatively, or two of them can be set, or all of them can be set, which is not limited here.
[0051] As for the back side of the isolation film 23, it can be not coated with the insulating glue 234, or it can be coated with the insulating glue 234, which is not limited here. In an embodiment, the back side of the isolation film 23 is coated with the insulating glue 234. In the solution of the present embodiment, because the back side of the isolation film 23 is coated with the insulating glue 234, the insulating glue 234 on the back side of the insulation part 231 can be bonded with the insulating glue 234 on the front side of the bearing part 233, improving the tightness of the combination between the insulation part 231 and the bearing part 233, and the insulating glue 234 on the back side of the bearing part 233 can be bonded with the insulating glue 234 on the front side of the heat insulation part 232, improving the tightness of the combination between the heat insulation part 232 and the bearing part 233. In some embodiments, the heat insulation part 232 is wound on the outside of the bearing part 233 for multiple layers. At this time, the insulating glue 234 on the back side of the inner heat insulation part 232 can be bonded with the insulating glue 234 on the front side of the outer heat insulation part 232, improving the tightness of the connection between the multiple layers.
[0052] Further, the specific implementation form of the heating component 20 is not limited, which can be a heating net, a carbon fiber heating body, a printed circuit and the like. Specifically, the carbon fiber heating body is a tubular heating body made of carbon fiber as a basic heating material, which utilizes a reflecting surface for heat dissipation, and the electric heating conversion rate is above 95%, which is 30% more energy-saving than nickel-chromium and tungsten-molybdenum materials as heating bodies. When the isolation film 23 is a PI film, the heating component 20 can also be a printed circuit, so as to print the printed circuit on the PI film, and after printing, the PI film is wound on the outside of the heat conduction body, so as to form the heating module.
[0053] The specific implementation form of the insulating glue 234 is not limited, and can be epoxy glue, polyurethane glue, silicone glue, acrylic glue, etc., which is not limited herein. In an embodiment, the insulating glue 234 is tpi glue (thermoplastic polyimide glue) which has thermoplasticity and good insulation performance, and is in the form of bonding, so that the heat conduction member 40, the heating assembly 20 and the isolation film 23 are closely combined together, effectively avoiding the generation of bubbles, and avoiding the influence of the expansion of the bubbles on the stability of the heating module 10.
[0054] Please refer to Figure 1 , the cigarette 1 is divided into a smoking segment, a cooling segment and a filter segment, the smoking segment includes a first smoking segment 11 close to the filter segment and a second smoking segment 12, the first heating unit 21 is used for heating the first smoking segment 11 of the cigarette 1, and the second heating unit 22 is used for heating the second smoking segment 12 of the cigarette 1. In this way, the first heating unit 21 heats the first smoking segment 11, and the generated smoke is close to the distance of the filter segment, so that the user can quickly smoke.
[0055] It should be noted that the first heating unit 21 and the second heating unit 22 are sequentially arranged 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. In a further embodiment, the temperature rising rate of the first heating unit 21 is higher than that of the second heating unit 22, and the specific implementation form is not limited, which can be that the heating power of the first heating unit 21 is larger, or when the heating power of the first heating unit 21 and the second heating unit 22 is the same, the heating area of the first heating unit 21 is smaller, etc., which is not limited herein.
[0056] The temperature rising rate refers to the length of time for heating the cigarette 1 from normal temperature to smoking temperature, for example, the longer the time for heating the cigarette 1 from normal temperature to smoking temperature, the slower the temperature rising rate, and vice versa, the shorter the time, the faster the temperature rising rate.
[0057] 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.
[0058] 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 the whole section is now only used for local heating, greatly improving the smoking efficiency of the cigarette 1.
[0059] 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 and 1Ω.
[0060] Further, in an embodiment, the insulating portion 231 surrounds the outer side of the heat-conducting member 40 for one turn, and the heat-insulating portion 232 surrounds the outer side of the heat-conducting member 40 for at least three turns.
[0061] The insulating portion 231 surrounds the outer side of the heat-conducting member 40 for one turn, i.e., only one layer of the isolation film 23 is arranged between the heating assembly 20 and the heat-conducting member 40. While achieving insulation between the heating assembly 20 and the heat-conducting member 40, the influence of the one layer on heat transfer between the heating member and the heat-conducting member 40 is small.
[0062] The heat-insulating portion 232 surrounds the outer side of the heat-conducting member 40 for at least three turns, so that the heat-insulating portion 232 can form at least three layers of heat insulation on the outer side of the heating assembly 20, avoid heat leakage from the heating assembly 20, and reduce heat loss. The heat-insulating portion 232 has at least three layers, and after being wound in multiple layers, the isolation film 23 can stand up in the width direction, facilitating subsequent assembly.
[0063] 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 embodiment or all the technical advantages.
[0064] The heating module and the electronic smoking set provided by the embodiments of the present application are described in detail above, and the principles and implementation manners 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 manners and application ranges 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.
