[0034] 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.
[0035] Currently, the heating module of heat-not-burn needs to roll the heating net, so as to roll the heating net into a shape close to a ring, so as to heat the periphery of the cigarette, and the pins of the heating net have the problem of difficult rolling.
[0036] For this purpose, please refer to Figures 1 to 3 The embodiment of the present application provides a heating net 10, which comprises a heating wire structure, two pins 12 and a strength reduction structure. The heating wire structure comprises a plurality of parallel heating wires 11. The two pins 12 are arranged at the two ends of the plurality of heating wires 11, and each pin 12 is connected to one end of the plurality of heating wires 11. The strength reduction structure is arranged on the pin 12 to reduce the strength of the pin 12.
[0037] It should be noted that the number of heating wires 11 is not limited, and can be two, three, four, etc., which is not limited here. The plurality of heating wires 11 are arranged in parallel, that is, not intersected, so that the short circuit phenomenon caused by the mutual contact between the plurality of heating wires 11 can be avoided. Two pins 12 are arranged at two ends of the plurality of heating wires 11. Specifically, one is located at the leading end of the heating wire 11, and the other is located at the tail end of the heating wire 11. Each pin 12 is connected to one end of at least part of the heating wire 11. One pin 12 can be connected to the leading end of all heating wires 11, and the other pin 12 can be connected to the tail end of all heating wires 11, so that when powered on, the pin 12 guides the current to the heating wire 11, and the heating wire 11 flows out from the other pin 12 after heating. Of course, the pin 12 can also be connected to only part of the leading end or tail end of the heating wire 11, for example, one pin 12 is connected to the leading end of all heating wires 11, and the other pin 12 is connected to the tail end of part of the heating wire 11, etc. The number of pins 12 is at least two, and the number of pins 12 is not limited to two, which can also be three, four, five, etc.
[0038] The specific implementation of the strength reduction structure is not limited, which can be in the form of slotting, reducing the thickness of part of the pin 12 by slotting to reduce its strength. It can also be in the form of opening hole 13, or in the form of breaking, so as to divide the whole pin 12 into multiple plates, etc. The specific implementation of the strength reduction structure is not limited.
[0039] It should be noted that the existing pin 12 is a sheet with uniform thickness and no opening and thickness reduction design, so that its strength is large and it is not easy to bend.
[0040] In the embodiment, the strength of the pin 12 is reduced by arranging the strength reduction structure at the pin 12 of the heating net 10, so that the pin 12 can be easily bent, and the pin 12 of the heating net 10 can be more easily attached to the heat pipe during the rolling process, reducing the difficulty of the heating net 10 in the rolling process.
[0041] Further, in an embodiment, the thickness of the pin 12 at the strength reduction structure is less than the thickness of the pin 12 at other positions. In the technical solution of the embodiment, the thickness of the pin 12 at the strength reduction structure is less than the thickness of the pin 12 at other positions, so that the overall strength of the pin 12 can be reduced and the pin 12 can be deformed more easily.
[0042] Specifically, the strength reduction structure is not limited to thinning the strength, which can be in the form of a slot, or in the form of a hole, etc., which is not limited here.
[0043] It can be understood that the thickness of the pin 12 of the heating net 10 is very thin, generally less than 0.5mm, so it is difficult to open a slot on the pin 12, in an embodiment, the strength reduction structure includes a through hole 13 opened on the pin 12, the through hole 13 penetrates the pin 12 along the thickness direction of the pin 12, in the technical solution of the embodiment, by opening the through hole 13, the overall structure of the pin 12 can be damaged, the strength can be greatly reduced, and the pin 12 can be easily deformed, and the through hole 13 is easier to produce and process.
[0044] Further, a plurality of gaps are formed between a plurality of heating wires 11, one of the gaps is located on a straight line with the through hole 13, which is arranged in the process of production and processing, after the gap is produced and processed, the through hole 13 can be produced and processed at the same time, which improves the production and processing efficiency.
[0045] It should be emphasized that the shape of the through hole 13 is not limited, which can be any shape, such as circular, rectangular, square, etc., which is not limited here, in an embodiment, the through hole 13 is a long hole, and the extension direction of the long hole is consistent with the length direction of the pin 12, which is arranged to reduce the strength of the pin 12.
[0046] Further, the through hole 13 is not limited to be opened at any position on the pin 12, which is not limited here.
[0047] In an embodiment, the pin 12 has a first connecting section 121 and a second connecting section 122 arranged in sequence in the length direction thereof, the width of the first connecting section 121 is greater than the width of the second connecting section 122, the two ends of the first connecting section 121 are connected with the heating wire 11 and the second connecting section 122 respectively, and the through hole 13 is opened on the first connecting section 121.
[0048] In the technical solution of the embodiment, the width of the first connecting section 121 is greater than the width of the second connecting section 122, so that the resistance of the pin 12 can be smaller, the heating amount of the pin 12 is smaller when powered on, and the strength of the first connecting section 121 is greater, so that the bending difficulty of the first connecting section 121 is greater when the pin 12 is bent, therefore, by opening the through hole 13 on the first connecting section 121, the strength of the first connecting section 121 can be effectively reduced, and the first connecting section 121 can be easily bent.
[0049] The through hole 13 can be arranged at the top of the first connecting section 121, or at the bottom of the first connecting section 121, and the like, which is not limited herein. In an embodiment, the first connecting section 121 has a first edge and a second edge arranged in sequence in the width direction of the first connecting section 121. The distance between the through hole 13 and the first edge in the width direction of the first connecting section 121 is a, and the distance between the through hole 13 and the second edge in the width direction of the first connecting section 121 is b, where -1mm≤a-b≤1mm. In the technical solution of the embodiment, the difference between the two distances between the through hole 13 and the first edge and the second edge is within 1mm, so that the through hole 13 is arranged at the approximate middle of the width direction of the first connecting section 121, which is more prone to bending.
[0050] In addition, the distance between the two pins 12 of the existing heating net 10 is generally small, so that the two pins 12 are easy to contact each other during the rolling process of the heating net 10, thereby causing a short circuit phenomenon. Therefore, in an embodiment, the width of the heating net 10 is c, and the distance between the two pins 12 is d, where d≥0.3c. In the embodiment, the distance between the two pins 12 is at least 30% of the overall width of the heating net 10, so as to ensure that the distance between the two pins 12 is large enough to avoid short circuit caused by contact during rolling.
[0051] It should be emphasized that the specific implementation form of the heating wire 11 is not limited, which can be in the form of a resistance wire, or in the form of a carbon fiber heating wire, and the like, which is not limited herein.
[0052] The embodiment of the present application also provides a heating module, which comprises the heating net 10. The heating net 10 adopts one or all of the technical solutions of the foregoing embodiments, and thus has the technical advantages of the foregoing embodiments.
[0053] Specifically, the heating net 10 comprises a heating wire structure, two pins 12 and a strength reduction structure. The heating wire structure comprises a plurality of parallel heating wires 11. The two pins 12 are arranged at two ends of the plurality of heating wires 11, and each pin 12 is connected to one end of the plurality of heating wires 11. The strength reduction structure is arranged on the pin 12 to reduce the strength of the pin 12.
[0054] In the embodiment, the strength of the pin 12 is weakened by arranging the weakening structure at the pin 12, so that the pin 12 can be easily bent, and thus the pin 12 of the heating net 10 can be easily attached to the heat conducting pipe during the rolling process, and the difficulty of the heating net 10 in the rolling process is reduced.
[0055] In some embodiments, the heating module further comprises an isolation film 23, the heating net 10 is bonded to the isolation film 23, and is wound together with the isolation film 23 and the outer side of the heat conducting pipe. By bonding the heating net 10 to the isolation film 23 and winding together with the isolation film 23 and the outer side of the heat conducting pipe, the isolation film can be wound on the outer side of the heating net 10, and the heat emitted by the heating net 10 is blocked, avoiding the heat from being emitted outward.
[0056] The isolation film 23 comprises a first film segment 231 located between the heat conducting pipe and the heating net 10, and a second film segment 232 located on the outer side of the heating net 10; wherein the first film segment 231 surrounds the outer side of the heat conducting pipe for one turn, and the second film segment 232 surrounds the outer side of the heat conducting pipe for at least three turns.
[0057] In the technical solution of the embodiment, the heating net 10 is arranged on the outer side of the heat conducting pipe, so that the heat emitted by the heating net 10 can be transmitted to the cigarette by the heat conducting pipe, and the cigarette is heated, and the heat conducting pipe can play the role of heat conduction and heat equalization.
[0058] It can be understood that the heat conducting pipe can be a metal pipe or a plastic pipe, which is not limited herein. When the heat conducting pipe is a metal pipe, the first film segment 231 can play the role of insulation between the heating net 10 and the heat conducting pipe, so as to avoid the short circuit of the heating net 10 by the heat conducting pipe.
[0059] The first film segment 231 surrounds the outer side of the heat conducting pipe for one turn, that is, only one layer of isolation film 23 is arranged between the heating net 10 and the heat conducting pipe, which realizes the insulation between the heating net 10 and the heat conducting pipe, and has little influence on the heat transfer between the heating element and the heat conducting pipe due to the only one layer.
[0060] The second film segment 232 surrounds the outer side of the heat conducting pipe for at least three turns, so that the second film segment 232 can form at least three layers of heat insulation on the outer side of the heating net 10, avoid the heat generated by the heating net 10 from leaking out, and reduce heat loss. The second film segment 232 has at least three layers, and after being wound in multiple layers, the isolation film 23 can stand up in the width direction, which is convenient for subsequent assembly.
[0061] The isolation film 23 can be a PI film (polyimide film) that has good thermal conductivity, insulation, adhesion, radiation resistance, and can be used for a long time in the temperature range of the heating of the smoking set.
[0062] In the production process, the heating net 10 can be placed on the isolation film 23 at a position, the width of the heating net 10 is b; the isolation film 23 has a first length edge in the length direction; the distance between the heating net 10 and the first length edge is a; wherein a > b, in the rolling process, the part of the heating net 10 and the first length edge forms the first film segment 231, and the other part forms the second film segment 232.
[0063] In an embodiment, the heating net 10 can further include a first heating unit 21 and a second heating unit 22 arranged in sequence along the length direction of the heat conduction pipe, wherein the first heating unit 21 and the second heating unit 22 are arranged in an alternating heating manner.
[0064] In this way, only one heating unit in the heating module heats at a time, so that the power supply of the electronic smoking set only needs to supply power to one of the first heating unit 21 and the second heating unit 22 during heating, and 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 only used for heating the local part, greatly improving the smoking efficiency of the cigarette.
[0065] The present application also provides an electronic smoking set, which includes a heating module. The heating module adopts one or all of the technical solutions of the above-mentioned embodiments, and thus has the technical advantages of the above-mentioned embodiments.
[0066] The heating net, 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 applying specific examples in this paper. The above description of the embodiments is only used to help understand the method of the present application and its core idea; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range will be changed, and the above description should not be understood as a limitation of the present application.
