[0001] This application claims priority to Chinese Patent Application No. 202510107100.2, filed January 22, 2025, entitled "Smoke Generating Device, Tobacco Cartridge, Smoke Generating Body, and Method for Preparation"; and also claims priority to Chinese Patent Application No. 202610077778.5, filed January 20, 2026, entitled "Wire, Composite Wire, Smoke Generating Body, and Tobacco Cartridge". The entire contents of the above applications are incorporated herein by reference. Technical Field

[0002] This application relates to the field of heated non-combustible technology, and in particular to a wire, a composite strand wire, a smoke generator, and a smoke cartridge. Background Technology

[0003] Reconstituted tobacco sheet, also known as recycled tobacco or homogenized tobacco, is a thin, regenerated product made primarily from tobacco leaves, stems, and dust, supplemented with plant fibers and chemical additives, through physical and chemical methods. Its properties are close to or superior to those of natural tobacco leaves. It is typically recycled in roll form and can be called reconstituted tobacco sheet paper. The tobacco sheet is used to produce a smoke-like substance that has the original flavor of tobacco when heated but not burned. This type of smoke-like substance is formed by stacking multiple layers of tobacco sheets or by rolling multiple layers of tobacco sheets into a long, thin cylindrical shape. However, this type of smoke-like substance still has some shortcomings. Summary of the Invention

[0004] This application provides a wire, a composite strand wire, a smoke generator, and a smoke cartridge to at least partially solve the above-mentioned technical problems.

[0005] In a first aspect, embodiments of this application provide a wire for use as a smoke generator, the wire being configured to be formed by twisting a smoke-generating strip, wherein the tensile strength of the smoke-generating strip is not greater than 10 N / m. 2 The twist of the wire is between the first preset value and the second preset value.

[0006] Secondly, the application embodiment provides a composite strand wire, which includes at least two of the above-mentioned wires, the at least two wires being in contact with each other, and each wire extending along a predetermined direction.

[0007] Thirdly, the application provides a composite strand wire, comprising: the aforementioned wire; a sensor, wherein a smoke-generating strip is twisted and wound around the sensor.

[0008] Fourthly, the application provides a composite strand wire, comprising: the wire described above; a sensor, wherein one of the sensor and the wire is wound around the periphery of the other, or the sensor and the wire are twisted together.

[0009] Fifthly, the application provides a smoke generator, which includes at least one of the following: a plurality of the above-described wires; or at least one of the above-described composite strands.

[0010] Sixthly, the application provides a tobacco cartridge, which includes the smoke-generating body of any of the above.

[0011] In the wire of this application embodiment, the tensile strength is not greater than 10 N / m. 2 The smoke-generating strip is twisted to form a wire, and the twist of the wire is between a first preset value and a second preset value. Since the twisted wire has a helical structure, on the one hand, the wire can convert the circumferential tensile load of the smoke-generating strip into the internal tensile stress of the wire, thereby giving the twisted wire of the smoke-generating strip a higher tensile strength than the smoke-generating strip. On the other hand, when the wire is subjected to tension in the twisting axis, the wire can absorb energy through untwisting instead of breaking directly, thereby giving the twisted wire of the smoke-generating strip a higher tensile strength than the smoke-generating strip.

Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] Reconstituted tobacco sheet, also known as recycled tobacco or homogenized tobacco, is a thin, regenerated product made primarily from tobacco leaves, stems, and dust, supplemented with plant fibers and chemical additives, through physical and chemical methods. Its properties are close to or superior to those of natural tobacco leaves. It is typically recycled in roll form and can be called reconstituted tobacco sheet paper. The tobacco sheet is used to produce a smoke-like substance that has the natural flavor of tobacco when heated but not burned. This type of smoke-like substance is formed by stacking multiple layers of tobacco sheets or by rolling multiple layers of tobacco sheets into a long, thin cylindrical shape. However, this type of smoke-like substance still has shortcomings. Specifically…

[0048] Tobacco strips are strip-shaped tobacco products with a fixed width and thickness. The raw materials can be tobacco sheets or natural tobacco leaves, and they are produced through processes such as calendering and slitting, resulting in a form between tobacco sheets and shredded tobacco. For example, tobacco strips are made by further calendering and slitting tobacco sheets; or, tobacco strips are made directly from natural tobacco leaves through shredding and calendering.

[0049] Currently, the mainstream Philip Morris (PMI) manufactures tobacco sheets by embossing them to create continuous indentations, then using a winding machine to roll the tobacco sheets into a cylindrical shape, thus achieving high-speed production. The reason PMI does not use tobacco strips for direct winding is that tobacco strips have insufficient tensile strength and a high probability of breakage during high-speed production. Therefore, they can only emboss the tobacco sheets to ensure regular winding and high-speed production. However, this process results in increased draw resistance, i.e., higher draw resistance. This is because after the tobacco sheets are embossed and wound into a smoke-generating body, the individual pieces are connected, hindering the passage of air.

[0050] One of the objectives of this application is to enable high-speed production of tobacco strips for tobacco products. The medium-speed test line for HNB (Heated Tobacco Products) cigarettes requires 2000 cigarettes / minute, the standard high-speed line 5000 cigarettes / minute, and the top-speed line 8000 cigarettes / minute. The production speed will decrease slightly if metal sheets are used. If breakage occurs during production due to insufficient tensile strength, reconnection is necessary, resulting in extremely high costs. Furthermore, high-speed machines are expensive and difficult to debug, making it difficult to achieve rapid continuous production through multiple slow machines. Currently, PMI's high-speed production line for Iluma tobacco products typically has a capacity of 180,000-480,000 cigarettes / hour. Excessive speed can lead to breakage of the tobacco sheet, reducing production efficiency and yield. If textile-type tobacco products are required, even higher tensile strength is needed, especially for textile-type tobacco products that require weaving; the tensile strength of the yarn must meet the minimum tensile strength requirements for textile yarns.

[0051] To address the aforementioned technical problems, this application provides a wire, a composite strand wire, a smoke generator, and a smoke cartridge. The term "wire" in the names of wire, composite strand wire, etc., used in this application should not be interpreted as a limitation on the cross-section.

[0052] According to a first aspect of this application, referring to Figures 1 to 6, this disclosure provides a wire 13 configured to be formed by twisting a smoking strip 12, wherein the tensile strength of the smoking strip 12 is not greater than 10 N / m. 2 The twist of wire 13 is between the first preset value and the second preset value.

[0053] Optionally, the second preset value is greater than the first preset value.

[0054] It should be noted that if the twist of the thread 13 is less than the first preset value, the thread 13 will break or be prone to breakage if it is used as a textile thread in the textile operation; if the twist of the thread 13 is greater than the second preset value, the smoke strip 12 will break or be prone to breakage during twisting.

[0055] The technical solution disclosed herein involves a tensile strength not exceeding 10 N / m. 2 The smoke-generating strip 12 is twisted to form a wire 13, and the twist of the wire 13 is between a first preset value and a second preset value. Because the twisted wire 13 has a helical structure, on the one hand, the wire 13 can convert the circumferential tensile load of the smoke-generating strip 12 into internal tensile stress, thereby giving the twisted wire 13 a higher tensile strength than the smoke-generating strip 12. On the other hand, when the wire 13 is subjected to tension in the twisting axis X, the wire 13 can absorb energy through untwisting instead of breaking directly, thus giving the twisted wire 13 a higher tensile strength than the smoke-generating strip 12. Furthermore, since the tensile strength of the smoke-generating strip 12 is no greater than 10 N / m... 2 When the twist of the wire 13 is between the first preset value and the second preset value, the untwisting stress of the wire 13 itself is very small, so the wire 13 can maintain or basically maintain the shape after the twisting of the smoke strip 12.

[0056] It should be noted that the external force experienced by the yarn 13 during the textile process is mainly the tension along the twisting axis X. Therefore, the tensile strength of the yarn 13 primarily refers to its tensile strength along the twisting axis X, while the tensile strength of the smoke-generating strip 12 primarily refers to its tensile strength along its length. It is understood that the higher tensile strength of the yarn 13 formed by twisting the smoke-generating strip 12 compared to the smoke-generating strip 12 is not limited to the tensile strength along the twisting axis X, but also includes the tensile strength in other directions intersecting with the twisting axis X. For example, the yarn 13 formed by twisting the smoke-generating strip 12 also has a higher tensile strength than the smoke-generating strip 12 in directions perpendicular to the twisting axis X.

[0057] In embodiments of this disclosure, both the smoke-generating strip 12 and the wire 13 contain tobacco plant components, adhesives, fogging agents, and flavorings. The tobacco plant components typically contain nicotine free bases and nicotine salts, such as nicotine citrate, nicotine malate, and nicotine tartrate; they also contain trace amounts of other nicotine compounds, such as nornicotine, anatabine, myosmine, and anabasine.

[0058] Optionally, the tobacco plant components include tobacco plant fiber and tobacco plant extracts, which contain nicotine free bases and nicotine salts, such as nicotine citrate, nicotine malate, and nicotine tartrate; and also contain trace amounts of other nicotine compounds, such as nornicotine, anatabine, myosmine, and anabasine.

[0059] Optionally, there are no restrictions on the selection of tobacco plant components, which may be derived from at least one of tobacco scraps, tobacco leaves, tobacco stems, and tobacco stalks. This disclosure does not impose any specific limitations in this regard.

[0060] Optionally, different polyols or mixtures thereof may be used as fogging agents, such as propylene glycol, vegetable glycerin, and polyethylene glycol, and may also include esters of polyhydroxy alcohols or esters of hydroxy acids. These fogging agents have significantly different volatilization temperatures; for example, glycerol and 1,3-butanediol have boiling points of 290°C and 207.5°C, respectively, at 760 mmHg. However, this application defines the boiling point temperature range as 180-350°C.

[0061] Alternatively, flavorings serve to impart various flavors and contain natural flavorings such as vanillin, menthol, eugenol, citral, linalool, ethyl acetate, other fruit and spice extracts; and synthetic flavorings such as acetylpyrazine, diacetyl, cyclic ketones, and various esters.

[0062] Optionally, the smoke-generating strip 12 may also contain non-tobacco plant components and / or a drying and strengthening agent. The non-tobacco plant components include non-tobacco plant fibers and non-tobacco plant extracts, and the drying and strengthening agent includes at least one of natural animal and plant gums, synthetic resins, and water-soluble cellulose derivatives.

[0063] It should be noted that wire 13 and smoke strip 12 are two different forms of the same material, and there is no difference in their composition.

[0064] As shown in Figures 3 and 6, in the embodiments of this disclosure, the wire 13 includes a plurality of spiral turns 137. At least two adjacent spiral turns 137 are spaced apart along the twisting axis X. At least two adjacent spiral turns 137 are adjacent to each other along the twisting axis X. At least two adjacent spiral turns 137 partially overlap. On the one hand, the frictional force between two partially overlapping adjacent spiral turns 137 can prevent slippage between the spiral turns 137, thereby bearing the load. Therefore, the partially overlapping adjacent spiral turns 137 can also improve the tensile strength of the wire 13. On the other hand, since there are spaced adjacent spiral turns 137 and partially overlapping adjacent spiral turns 137 in the wire 13, a concave-convex structure 130 is formed on the surface of the wire 13. When the wire 13 is applied to the smoke generator 100, a channel with concave-convex buffer space is formed inside the smoke generator 100, which is not a completely smooth channel. Therefore, this wire 13 is also beneficial for cooling when the airflow passes through. Moreover, this structural feature, combined with the adjustable wire gap 1A described below, can constitute a better airflow speed control method. Specifically, the concave-convex structure 130 includes a concave structure a formed by spaced adjacent spiral turns 137 and a convex structure b formed by partial overlap of adjacent spiral turns 137.

[0065] When the twist of wire 13 is between a first preset value and a second preset value, as the twist of wire 13 increases, wire 13 can have the following structure:

[0066] Within the first twist range, the number of spiral turns 137 spaced apart along the twisting axis X in the wire 13 is relatively large; specifically, the number of spiral turns 137 spaced apart along the twisting axis X in the wire 13 is greater than the number of spiral turns 137 adjacent along the twisting axis X in the wire 13, and the number of spiral turns 137 spaced apart along the twisting axis X in the wire 13 is greater than the number of partially overlapping spiral turns 137 in the wire 13.

[0067] Within the second twist range, the number of spiral turns 137 adjacent to each other along the twisting axis X in the wire 13 is relatively large; specifically, the number of spiral turns 137 adjacent to each other along the twisting axis X in the wire 13 is greater than the number of spiral turns 137 spaced apart along the twisting axis X in the wire 13, and the number of spiral turns 137 adjacent to each other along the twisting axis X in the wire 13 is greater than the number of partially overlapping spiral turns 137 in the wire 13.

[0068] Within the third twist range, the proportion of partially overlapping spiral turns 137 in the wire 13 is relatively large; specifically, the proportion of partially overlapping spiral turns 137 in the wire 13 is greater than the proportion of spiral turns 137 adjacent along the twisting axis X in the wire 13, and the proportion of partially overlapping spiral turns 137 in the wire 13 is greater than the proportion of spiral turns 137 spaced apart along the twisting axis X in the wire 13.

[0069] In some implementations, the first preset value is no greater than 45 twists / m, and the second preset value is no less than 50 twists / m.

[0070] Optionally, the first preset value can be 45 twists / m, 44 twists / m, 43 twists / m, 42 twists / m, 41 twists / m, 40 twists / m, 39 twists / m, 38 twists / m, 37 twists / m, 36 twists / m, 35 twists / m, 34 twists / m, 33 twists / m, 32 twists / m, 31 twists / m, 30 twists / m, 29 twists / m, 28 twists / m, 27 twists / m, 2 The first preset value can be 6 twists / m, 25 twists / m, 24 twists / m, 23 twists / m, 22 twists / m, 21 twists / m, 20 twists / m, 19 twists / m, 18 twists / m, 27 twists / m, 16 twists / m, 15 twists / m, 14 twists / m, 13 twists / m, 12 twists / m, 11 twists / m, 10 twists / m, 9 twists / m, 8 twists / m, 7 twists / m, 6 twists / m, or 5 twists / m, etc. It is understood that the first preset value is not limited to the values ​​mentioned above; for example, the first preset value can also be between two of the above values. This disclosure does not specifically limit this.

[0071] Optionally, the second preset value can be 50 twists / m, 51 twists / m, 52 twists / m, 53 twists / m, 54 twists / m, 55 twists / m, 56 twists / m, 57 twists / m, 58 twists / m, 59 twists / m, 60 twists / m, 61 twists / m, 62 twists / m, 63 twists / m, 64 twists / m, 65 twists / m, 66 twists / m, 67 twists / m, 68 twists / m, 69 twists / m, 70 twists / m, 71 twists / m, 72 twists / m, 73 twists / m, 74 twists / m. The values ​​are 75 twists / m, 76 twists / m, 77 twists / m, 78 twists / m, 79 twists / m, 80 twists / m, 81 twists / m, 82 twists / m, 83 twists / m, 84 twists / m, 85 twists / m, 86 twists / m, 87 twists / m, 88 twists / m, 89 twists / m, 90 twists / m, 91 twists / m, 92 twists / m, 93 twists / m, 94 twists / m, 95 twists / m, 96 twists / m, 97 twists / m, 98 twists / m, 99 twists / m, or 100 twists / m, etc. It is understood that the second preset value is not limited to the values ​​mentioned above; for example, the second preset value can also be between the two values ​​mentioned above. This disclosure does not specifically limit this.

[0072] In some implementations, the first preset value is between 40 twists / m and 45 twists / m, and the second preset value is between 50 twists / m and 60 twists / m.

[0073] As shown in Figures 3 and 4, in some embodiments, the twist of the thread 13 is between 40 twists / m and 60 twists / m. That is, the twist of the thread 13 is within the second twist range. At this time, since the number of spiral turns 137 adjacent to each other along the twisting axis X accounts for a large proportion of the thread 13, the thread 13 per unit length can achieve the preset weight and the roundness of the thread 13 is better. The thread 13 with better roundness is not only aesthetically pleasing, but also easier to weave when the thread 13 is used as a textile thread.

[0074] It should be noted that when the twist of the wire 13 is less than 40 twists / m, that is, the twist of the wire 13 is within the first twist range, the number of spiral turns 137 arranged at intervals along the twisting axis X in the wire 13 is relatively large. Therefore, when the wire 13 is applied to the smoke generator 100, it is necessary to set a longer wire 13 or / and increase the number of wires 13 to ensure the smoke generation effect of the smoke generator 100. When the twist of the wire 13 is greater than 60 twists / m, that is, the twist of the wire 13 is within the third twist range, the number of partially overlapping spiral turns 137 in the wire 13 is relatively large. The partially overlapping adjacent spiral turns 137 will cause the surface of the wire 13 to form an uneven structure 130, which will affect the appearance of the wire 13. Moreover, within this twist range, as the twist of the wire 13 increases, the difficulty of weaving the wire 13 will also increase.

[0075] Optionally, the twist of the wire 13 can be 40 twists / m, 41 twists / m, 42 twists / m, 43 twists / m, 44 twists / m, 45 twists / m, 46 twists / m, 47 twists / m, 48 twists / m, 49 twists / m, 50 twists / m, 51 twists / m, 52 twists / m, 53 twists / m, 54 twists / m, 55 twists / m, 56 twists / m, 57 twists / m, 58 twists / m, 59 twists / m, or 60 twists / m, etc. It is understood that the twist of the wire 13 is not limited to the above values; for example, the twist of the wire 13 can also be between the two values ​​mentioned above. This disclosure does not impose specific limitations in this regard.

[0076] In some embodiments, the twist of the wire 13 is between 45 twists / m and 50 twists / m.

[0077] In the embodiments of this disclosure, due to the high short fiber content of the smoke-generating strip 12, the tensile strength of the smoke-generating strip 12 is no greater than 10 N / m. 2 .

[0078] Optionally, the tensile strength of the smoke-generating strip 12 can be 1 N / m. 2 2N / m 23N / m 2 4N / m 2 5N / m 2 6N / m 2 7N / m 2 8N / m 2 9N / m 2 or 10N / m 2 wait.

[0079] Preferably, the tensile strength of the smoke-generating strip 12 is 7 N / m. 2 -10N / m 2 between.

[0080] Optionally, the tensile strength of the smoke-generating strip 12 can be 7 N / m. 2 7.2 N / m 2 7.4 N / m 2 7.6 N / m 2 7.8 N / m 2 8N / m 2 8.2 N / m 2 8.4 N / m 2 8.6 N / m 2 8.8 N / m 2 9N / m 2 9.2 N / m 2 9.4 N / m 2 9.6 N / m 2 9.8 N / m 2 or 10N / m 2 Etc. It is understood that the tensile strength of the smoke-generating strip 12 is not limited to the values ​​mentioned above; for example, the tensile strength of the smoke-generating strip 12 can also be between the two values ​​mentioned above. This disclosure does not specifically limit it in this regard.

[0081] In some embodiments, the tensile strength of wire 13 is not less than 15 N / m. 2 between.

[0082] Optionally, the tensile strength of wire 13 can be 15 N / m. 2 16N / m 2 17N / m 2 18N / m 2 19N / m 2 20N / m 2 21N / m 2 22N / m 2 23N / m 2 24N / m 2 25N / m 2 26N / m 2 27N / m2 28N / m 2 29N / m 2 30N / m 2 31N / m 2 32N / m 2 33N / m 2 34N / m 2 35N / m 2 36N / m 2 37N / m 2 38N / m 2 39N / m 2 40N / m 2 Etc. It is understood that the tensile strength of wire 13 is not limited to the values ​​mentioned above; for example, the tensile strength of wire 13 may also be between the two values ​​mentioned above. This disclosure does not specifically limit it in this regard.

[0083] In some embodiments, the ratio of the tensile strength of the wire 13 to the tensile strength of the smoke strip 12 is 1.5 or higher.

[0084] Optionally, the ratio of the tensile strength of the wire 13 to the tensile strength of the smoke strip 12 can be 1.5, 1.6, 1.7, 18, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, or 4.0. It is understood that the ratio of the tensile strength of the wire 13 to the tensile strength of the smoke strip 12 is not limited to the values ​​mentioned above; for example, the ratio can also be between the two values ​​mentioned above. This disclosure does not impose specific limitations in this regard.

[0085] In the embodiments of this disclosure, the wire 13 contains short fibers, the length of which is no greater than 38 mm, and the mass percentage of the short fibers in the wire 13 is no less than 50%. Because the wire 13 contains short fibers, the length of which is no greater than 38 mm, and the mass percentage of the short fibers in the wire 13 is no less than 50%, the tensile strength of the smoke-generating strip 12 is no greater than 10 N / m. 2 .

[0086] As shown in Figures 1 to 3 and Figure 6, the length of the smoke-generating strip 12 is L1, and correspondingly, the dimension of the wire 13 extending spirally along the twisting axis X is also L1; the width of the smoke-generating strip 12 is L2; ​​the thickness of the smoke-generating strip 12 is L3, and the dimension of the spiral turn 137 of the wire 13 in the twisting radial direction Y is also L3.

[0087] In some implementations, the ratio of L1 to L2 is not less than 10.

[0088] It is understandable that the ratio of L1 to L2 is not infinitely large, and an appropriate ratio of L1 to L2 can be selected according to actual needs. This disclosure does not impose specific limitations on this.

[0089] In some implementations, the ratio of L2 to L3 is greater than 1.

[0090] It is understandable that the ratio of L2 to L3 is not infinitely large, and an appropriate ratio of L2 to L3 can be selected according to actual needs. This disclosure does not impose specific limitations on this.

[0091] In some embodiments, the thickness L3 of the smoke-generating strip 12 is between 0.01 mm and 0.50 mm.

[0092] Optionally, the thickness L3 of the smoke-generating strip 12 can be 0.01 mm, 0.05 mm, 0.10 mm, 0.15 mm, 0.20 mm, 0.25 mm, 0.30 mm, 0.35 mm, 0.40 mm, 0.45 mm, or 0.50 mm, etc. It is understood that the thickness L3 of the smoke-generating strip 12 is not limited to the above values; for example, the thickness L3 of the smoke-generating strip 12 can also be between the above two values. This disclosure does not specifically limit it in this regard.

[0093] As shown in Figure 4, in some embodiments, the wire 13 is a hollow cylinder, and the equivalent diameter of the wire 13 is in the range of 0.02mm-1.5mm.

[0094] Optionally, the equivalent diameter of wire 13 is 0.02 mm, 0.06 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, or 1.5 mm. It is understood that the equivalent diameter of wire 13 is not limited to the above values; for example, the equivalent diameter of wire 13 can also be between two of the above values. This disclosure does not specifically limit it in this regard.

[0095] It should be noted that the equivalent diameter of the wire 13 is controllable. The equivalent diameter of the wire 13 can be controlled by controlling the thickness of the smoke strip 12 and / or the twist degree when the smoke strip 12 is twisted to form the wire 13.

[0096] It should also be noted that wire 13 also defines wire channel 131, which extends along the twisting axis X of wire 13. The equivalent diameter of wire channel 131 is controllable. The equivalent diameter of wire channel 131 can be controlled by controlling the thickness of smoke strip 12 and / or the twist degree when smoke strip 12 is twisted to form wire 13. When wire 13 is applied to smoke body 100 or composite strand 1, the extrusion pressure on wire 13 when it is bundled can also be controlled to control the deformation of wire 13, thereby controlling the equivalent diameter of wire channel 131.

[0097] As shown in Figure 5, in some embodiments, the wire 13 is roll-formed. The wire 13 includes a first portion 133 and a second portion 135 disposed opposite to each other. The first portion 133 and the second portion 135 are connected end to end, and the connection point of the first portion 133 and the second portion 135 has an acute angle. In other words, the wire 13 is spindle-shaped, that is, a shape in which the two ends of the wire 13 are pointed and the middle is wide. The shaping of the wire 13 can reduce the untwisting stress of the wire 13, thereby further enabling the wire 13 to maintain or substantially maintain the shape of the twisted smoke strip 12.

[0098] This disclosure also provides a method for preparing a smoke-generating line, comprising:

[0099] Form long strips, cut the smoking sheet into strips and roll them into long strip coils;

[0100] Twisting: Long strips are twisted to form smoke-generating wires.

[0101] Among them, the tensile strength of the long strip is not greater than 10 N / m. 2 The twisting degree is between the first preset value and the second preset value.

[0102] It should be noted that the smoke-generating line can be cut into multiple wires 13. The cutting is usually carried out after the multiple smoke-generating lines are formed into a smoke-generating bundle. That is, the smoke-generating line is a constituent unit of the smoke-generating bundle. At this time, the smoke-generating bundle can be cut into multiple smoke-generating bodies 100, among which the wires 13 are constituent units of the smoke-generating bodies 100.

[0103] As shown in Figure 31, this disclosure also provides an apparatus for preparing a smoke-generating line, comprising:

[0104] The tape feeding device 600 is used to drive the long strip reel to rotate so that the long strip reel releases the long strip at a first preset rate;

[0105] Twisting device 700 is used to twist the long strip released from the long strip reel to form a smoke-generating wire;

[0106] 800 winding device, winding and smoke-generating line;

[0107] The twisting device 700 includes a first roller 701, a second roller 703 spaced apart from the first roller 701, and a guide ring 705. The first roller 701 and the second roller 703 are used to drive the smoke-generating line to move at a second preset speed. The guide ring 705 is used for threading the long strip. At least one of the first roller 701 and the second roller 703 is a driving roller. The first roller 701 and the second roller 703 drive the smoke-generating line through friction. The second preset speed is less than the first preset speed so that the driving force provided by the first roller 701 and the second roller 703 is converted into a torsional force by the guide ring 705 to twist the long strip to form a smoke-generating line.

[0108] It should be noted that in the initial stage of twisting the long strip to form the smoke-generating line, a reinforcing core is needed as a guide to make the long strip continuously wound. After winding to a certain distance, the reinforcing core can be removed and the long strip can be wound continuously on its own.

[0109] According to a second aspect of this disclosure, as shown in Figures 7 to 10, a composite strand 1 is provided, comprising at least two wires 13 in contact with each other, and each wire 13 extending along a predetermined direction. This composite strand 1 possesses all the beneficial effects of the aforementioned wires 13, which will not be elaborated further herein.

[0110] In embodiments of this disclosure, the composite yarn 1 is formed by a textile process.

[0111] As shown in Figures 7 and 8, in some embodiments, the outermost layer of the composite strand 1 is a first shaping layer 11. The first shaping layer 11 may have the same layer structure as the second shaping layer 17 described later. That is, the first shaping layer 11 may be a thin aluminum foil composite paper with an average wall thickness of 0.3 mm. It contains at least two parallel stacked wires 13, each wire 13 is in a straight state, that is, at least two wires 13 form a wire bundle. It also contains a longitudinally straight wire channel 131 and a wire gap 1A. The wire channel 131 and the wire gap 1A are both constructed as part of the air passage. The wires 13 define the wire channel 131, and the wire gap 1A is formed between adjacent wires 13 and between the first shaping layer 11 and the wires 13. Furthermore, the wire gap 1A is controllable. The size of the wire gap 1A is controlled by controlling the outer diameter of adjacent wires 13, thereby controlling the equivalent inner diameter of the air passage. The outer diameter of the wire 13 can be controlled by controlling the thickness of the smoke strip 12 and / or the twist when the smoke strip 12 is twisted to form the wire 13. The wire channel 131 is also controllable. The equivalent diameter of the wire channel 131 can be controlled by controlling the thickness of the smoke strip 12 and / or the twist when the smoke strip 12 is twisted to form the wire 13. In the composite strand 1, the extrusion pressure on the wire 13 can also be controlled to control the deformation of the wire 13, thereby controlling the equivalent diameter of the wire channel 131. If the air passage of the composite wire 1 is divided into radial sections, the size of the wire gap 1A can be controlled by controlling the outer diameter of the adjacent wires 13 in different sections, and / or the equivalent inner diameter of the air passage in different sections can be controlled by controlling the equivalent diameter of the wire channel 131 in different sections, so as to meet the need for local adjustment of suction resistance, air intake, etc. due to the different smoke output caused by uneven heating of the composite wire 1.

[0112] It should be noted that when the compressive force on the wire 13 due to being bundled is insufficient to deform the wire 13, the wire channel 131 is the channel formed when the smoke strip 12 is twisted to form the wire 13; when the compressive force on the wire 13 due to being bundled is sufficient to deform the wire 13, the wire channel 131 is the remaining channel after the wire 13 is deformed. It can be understood that the greater the compressive force between adjacent wires 13, the more complex the shape of the wire channel 131, and the smaller the equivalent diameter of the wire channel 131.

[0113] It should also be noted that when the compressive force on the bundled wires 13 is insufficient to deform the wires 13, the wires 13 can be at least one of circular and spindle shapes in the cross section perpendicular to the axis of the composite strand 1; when the compressive force on the bundled wires 13 is sufficient to deform the wires 13, each wire 13 will have a different shape due to different deformation in the cross section perpendicular to the axis of the composite strand 1, and the deformation of each wire 13 is random, that is, the deformation of the wires 13 is different even if the number of wires 13, the initial shape of each wire 13, and the equivalent diameter of the bundled wires 13 remain unchanged.

[0114] It should also be noted that when wire 13 is manufactured using a twisting process, the surface of wire 13 is not smooth due to the presence of the concave-convex structure 130. (When multiple wires 13 are parallel, the gap 1A between the wires is not a completely flat and smooth channel, but has a concave-convex buffer space, which is also conducive to cooling when airflow passes through.) This structural feature of wire 13, combined with the aforementioned gap 1A between the wires, constitutes a better airflow speed control method.

[0115] Optionally, the number of wires 13 in the composite strand 1 can be 2, 3, 4, 5, 6, 7, 8, 9, or 10. It is understood that the number of wires 13 is not limited to the above values. This disclosure does not impose any specific limitations in this regard.

[0116] As shown in Figure 7, for example, the number of wires 13 is 4.

[0117] After shaping, the composite strand 1 has a circular outer perimeter, and its internal strands 13 are all made of the same material and are single, relatively thick strands. This internal configuration of the composite strand 1 is a single-strand configuration. In this design, the strands 13 are not intertwined or wrapped, and the numerous strand gaps 1A make the entire composite strand 1 very loose and breathable. When this composite strand 1 is applied to a smoke generator, it is expected to result in a lower draw resistance.

[0118] The difference between the embodiment shown in Figure 9 and the embodiment shown in Figure 8 is that, as shown in Figures 7 and 9, the composite strand 1 is twisted as a whole to make the wire 13 have an overall twisted shape. With this overall twist, on the one hand, the wire 13 is less likely to fall off during processing; on the other hand, the wire gaps 1A and wire channels 131 are no longer straight but spiral-shaped, extending the length of the airflow path, enhancing the effect of heat convection heat transfer, and contributing to the reduction of aerosol temperature.

[0119] It should be noted that the twisting direction of the smoke-generating strip 12 to form the wire 13 is opposite to the twisting direction of at least two wires 13 twisted together (i.e., following the principle of "alternating twist direction"), in order to achieve dynamic mechanical balance and prevent twisting. Specifically, one of the twisting directions of the smoke-generating strip 12 to form the wire 13 and the twisting direction of at least two wires 13 twisted together is "Z twist" and the other is "S twist". "Z twist" is usually defined as the rotation direction of the twisting stator being clockwise; "S twist" is usually defined as the rotation direction of the twisting stator being counterclockwise.

[0120] The difference between the embodiment shown in Figure 10 and the embodiment shown in Figure 8 is that, as shown in Figures 7 and 10, the composite strand 1 has a short rope-like structure. This short rope segment has a loose structure, including multiple strands 13 intertwined and woven together. The intertwining and weaving of multiple strands 13 makes it less likely for the strands 13 to fall off during processing. Furthermore, the gaps 1A and channels 131 between the strands are no longer straight, but rather the interweaving of the strands 13 extends the length of the airflow path, enhancing the effect of heat convection and contributing to a reduction in aerosol temperature.

[0121] It should be noted that in other embodiments, the composite strand 1 may not have a first shaping layer 11, and the bundle of multiple strands 13 can be externally bound or shaped using adhesive or other methods to achieve overall shaping of the composite strand 1.

[0122] External binding and shaping: The outer periphery of the wire bundle 13 is bound with one or more binding threads to achieve shaping. Alternatively, there is another implementation method, in which each wire 13 is bound by one or more binding threads inserted into the wire bundle 13 so that the binding threads are not exposed, or by a binding structure in which the same binding thread is partially inserted into the wire 13 and partially exposed outside the wire 13, such as by sewing, to achieve shaping.

[0123] Adhesive application for shaping: Adhesive is applied to at least the surface of the wires 13 before or after bundling, through spraying, soaking, or coating, so that the wires 13 can bond together upon contact, thereby shaping the bundled composite strands 1. Bonding can be done at one end of the composite strands 1, leaving the middle section with a loose structure. Alternatively, the entire length of the smoke generator 100 can be bonded while maintaining effective porosity and suction resistance. Furthermore, the adhesive hardens relatively after drying, which helps to shape the winding state of the wires 13 and supports the smoke generator 100.

[0124] It should also be noted that when the binding thread is used to bind the outer periphery of the wire bundle 13 for shaping, the binding thread can be made of the same material as the wire 13, the only difference being the length of the binding thread and the wire 13. The binding thread can be a metal wire or a fiber thread. When the binding thread is inserted into the wire bundle 13 to bind each wire 13 or partially inserted into the wire 13 through the same binding thread, the binding thread can be a metal wire or a fiber thread. The fiber thread can be various natural fibers (plant fibers and mineral fibers) or chemical fibers (man-made fibers, synthetic fibers, and inorganic fibers) that do not contain nicotine. Suitable natural fibers include plant fibers and mineral fibers that can withstand temperatures up to 250°C.

[0125] It should also be noted that when there are two wires 13 and the bundle of two wires 13 is formed by external binding or by adding adhesive to shape the composite strand 1, there is no wire gap 1A inside the composite strand 1.

[0126] According to a third aspect of this application, as shown in Figures 11 to 13, a composite strand 1 is provided. The composite strand 1 includes a wire 13 and a sensor 15, with a smoke-generating strip 12 twisted and wound around the sensor 15. In other words, the sensor 15 is inserted into the wire channel 131 of the wire 13. The sensor 15 is a single metal wire, meaning the composite strand 1 is a single yarn and single filament configuration. The metal wire can be a 0.2 mm diameter SUS 420 stainless steel round wire, which is a martensitic stainless steel and is magnetic. Since the smoke-generating strip 12 is twisted and wound around the sensor 15, the wire channel 131 of the wire 13 is filled by the sensor 15. Therefore, the equivalent diameter of the wire 13 is achieved only by controlling the equivalent diameter of the sensor 15 and / or controlling the thickness of the smoke-generating strip 12, and cannot be achieved by controlling the twist degree when the smoke-generating strip 12 is twisted to form the wire 13. Therefore, in addition to this effective effect, the composite strand 1 has all the other beneficial effects of the aforementioned wire 13, which will not be elaborated further in this disclosure. Furthermore, since the wire 13 is directly twisted onto the sensor 15, the friction between the wire 13 and the sensor 15 also helps to improve the tensile strength of the wire 13. Therefore, when the twist degree of the wire 13 is the same, directly twisting the wire 13 onto the sensor 15 can effectively improve the tensile strength of the wire 13, while when the tensile strength of the wire 13 is the same, the required twist degree for directly twisting the wire 13 onto the sensor 15 is lower. At the same time, the sensor 15 can rapidly increase its temperature in an alternating magnetic field through eddy current heating.

[0127] In the embodiments shown in Figures 11 to 13 of this disclosure, the composite strand 1 is cylindrical in shape.

[0128] In the embodiments shown in Figures 11 to 13 of this disclosure, the sensor 15 is magnetic. When the cartridge is used in conjunction with the electromagnetic smoking device, it couples with the high-frequency alternating electromagnetic field generated in the device, rapidly increasing its temperature through eddy current heating, and then heating the adjacent wire 13. Therefore, when multiple composite strands 1 are applied to the smoke generator 100 in this embodiment, the smoke generator 100 acts as a magnetic smoke generator, with its sensor 15 (heating element) discretely distributed throughout the smoke generator 100. This provides advantages such as easy cutting during processing and uniform heating and carbonization during operation.

[0129] Some applications derived from this implementation method include:

[0130] The sensor 15 is a physical unit, and its material composition is one of a single metal, a single alloy, or a composite metal. Examples of single metal wires include iron (Fe) wire, nickel (Ni) wire, and cobalt (Co) wire; examples of single alloy wires include various magnetic stainless steel wires (such as ferritic stainless steel, martensitic stainless steel, and some cold-worked austenitic stainless steel), various soft magnetic alloys (such as permalloy, iron-based amorphous alloy, cobalt-based amorphous alloy, iron-based nanocrystalline alloy, iron-silicon-aluminum alloy, Invar alloy, constant expansion alloy), and Kovar alloy wire, etc.; the sensor 15 is a composite metal wire, which contains two or more metal materials, including at least one magnetic material. Composite means that they are combined together by means of rolling, electroplating, electroless plating, sputtering, welding, cladding, and coating.

[0131] In other applications, to facilitate cutting the sensor 15 and achieve a more uniform distribution within the magnetic smoke generator 100, the sensor 15 can be composed of more and finer metal wires, such as 50 strands of equal-sized ultrafine magnetic metal wires with a diameter of 0.05 mm as the heating element. However, excessive heating elements are difficult to cut during sizing and can easily lead to over-carbonization or even scorching of the magnetic smoke generator 100 during smoking applications. Therefore, considering economic cost and manufacturability while achieving the necessary eddy current heating effect, this application sets the diameter of a single metal wire in the sensor 15 of the cartridge to between 0.01 and 1 mm.

[0132] In some other embodiments, the sensor 15 has a dual-wire structure, consisting of two magnetic metal wires of different materials twisted together. One wire is a stainless steel 410 (SUS410) round wire with a diameter of 0.12 mm; the other wire is a nickel (Ni) round wire with a diameter of 0.08 mm.

[0133] In other application scenarios and design parameters, the following are derived:

[0134] When the sensor 15 contains multiple metal wires, it can be called a multi-wire structure, such as a composite metal strand made of multiple metals wound together. There are three basic combinations of composite metal strands: magnetic metal wires wound with magnetic metal wires, magnetic metal wires wound with non-magnetic metal wires, and non-magnetic metal wires wound with non-magnetic metal wires. Regardless of the combination, at least two magnetic metal wires are required in the magnetic smoke generator. The magnetic metal wires can be made of the aforementioned magnetic materials. Non-magnetic metal wires include copper (Cu) wire, silver (Ag) wire, aluminum (Al) wire, titanium (Ti) wire, chromium (Cr) wire, and various highly ductile alloys (such as nickel-chromium alloys, silver-copper alloys, and aluminum alloys), all of which can withstand temperatures up to 500°C.

[0135] This disclosure also provides a method for preparing composite strands, including:

[0136] Form long strips by cutting the smoke-generating sheets into strips and rolling them into long strip coils;

[0137] The long strip is twisted and wound around the receptor wire to form a composite strand, in which the long strip is twisted to form a smoke-generating wire.

[0138] Among them, the tensile strength of the long strip is not greater than 10 N / m. 2 The twisting degree is between the first preset value and the second preset value.

[0139] It should be noted that the composite strand can be cut to form multiple composite strands 1. The cutting is usually carried out after the composite strand has formed a smoke bundle, that is, the composite strand is the constituent unit of the smoke bundle. At this time, the smoke bundle can be cut to form multiple smoke bodies 100, among which the composite strand 1 is the constituent unit of the smoke body 100.

[0140] As shown in Figure 32, this disclosure also provides an apparatus for preparing composite strands, comprising:

[0141] The tape feeding device 600 is used to drive the long strip reel to rotate so that the long strip reel releases the long strip at a first preset rate. The long strip reel has a through hole. The tape feeding device 600 is also used to drive the sensor wire reel so that the sensor wire reel releases the sensor wire at a second preset rate. The sensor wire passes through the through hole so that the long strip is located on the outer periphery of the sensor wire.

[0142] Twisting device 700 is used to wind the long strip released from the long strip reel onto the receptor wire through a twisting spiral to form a composite strand wire;

[0143] 800 winding device for winding composite strands;

[0144] The twisting device 700 includes a first roller 701, a second roller 703 spaced apart from the first roller 701, and a guide ring 705. The first roller 701 and the second roller 703 are used to drive the composite strands at a second preset speed. The guide ring 705 is used for threading the long strip and the sensor wire. At least one of the first roller 701 and the second roller 703 is a driving roller. The first roller 701 and the second roller 703 drive the composite strands through friction. The second preset speed is less than the first preset speed so that the driving force provided by the first roller 701 and the second roller 703 is converted into a torsional force by the guide ring 705 to twist the long strip into a smoking wire.

[0145] It should be noted that during the twisting process of the long strip, the receptor wire also serves as a guide for the twisting of the long strip.

[0146] According to a fourth aspect of this application, as shown in Figures 14 to 16, a composite strand 1 is provided. The composite strand 1 includes a wire 13 and a sensor 15, wherein one of the sensor 15 and the wire 13 is wound around the periphery of the other, or the sensor 15 and the wire 13 are twisted together. The composite strand 1 has all the other beneficial effects of the aforementioned wire 13, which will not be repeated here.

[0147] The difference between the embodiment shown in Figure 14 and the embodiments shown in Figures 11-13 is that, as shown in Figure 14, the sensor 15 is wrapped around the outer periphery of the wire 13.

[0148] It is understood that the sensor 15 can be wound around the periphery of a single wire 13, or the sensor 15 can be wound around the periphery of a whole formed by multiple wires 13.

[0149] As shown in Figure 15, in some embodiments, the wire 13 is wound around the outer periphery of the sensor 15.

[0150] It should be noted that the composite strand 1 formed by winding the wire 13 around the outer periphery of the sensor 15 and the composite strand 1 formed by twisting the smoke strip 12 around the sensor 15 are two different composite methods. When the wire 13 is wound around the outer periphery of the sensor 15, the wire 13 forms a double-layer structure on the outer periphery of the sensor 15; when the smoke strip 12 is twisted around the sensor 15, the wire 13 forms a single-layer structure on the outer periphery of the sensor 15.

[0151] As shown in Figure 16, in some embodiments, the receptor 15 and the wire 13 are twisted together. Both the receptor 15 and the wire 13 are in a twisted state.

[0152] It is understood that the sensor 15 can be twisted with a single wire 13 or with multiple wires 13. This disclosure does not specifically limit this.

[0153] In the embodiments shown in Figures 14 to 16, the wire 13 can be configured as a single yarn structure or a multi-yarn composite yarn structure. When forming the smoke generator 100, these feeding units can be programmed into ropes of different structures through various combinations. This disclosure does not specifically limit this.

[0154] It should be noted that the twisting direction of the smoke-generating strip 12 to form the wire 13 is opposite to the twisting direction of the sensor 15 and the wire 13 to form the composite wire 13.

[0155] According to a fifth aspect of this disclosure, as shown in Figures 17 to 28, a smoke generator 100 is provided, which includes a plurality of the aforementioned wires 13. The smoke generator 100 possesses all the beneficial effects of the aforementioned wires 13, which will not be elaborated further herein.

[0156] In embodiments of this disclosure, a plurality of wires 13 of the smoke generator 100 are in contact with each other, and each wire 13 extends along a predetermined direction.

[0157] As shown in Figures 17 and 18, in some embodiments, the outermost layer of the smoke-generating body 100 is a second shaping layer 17, which may be composed of a thin aluminum foil 171 composite paper with an average wall thickness of 0.3 mm. It contains multiple parallel stacked wires 13, each wire 13 being straight, i.e., multiple wires 13 forming a bundle. The interior also contains longitudinally straight wire channels 131 and wire gaps 1A, both of which constitute part of the air passage of the smoke-generating body 100. Furthermore, the wire gaps 1A are controllable; their size is controlled by controlling the outer diameter of adjacent wires 13, thereby controlling the equivalent inner diameter of the air passage. Similarly, the wire channels 131 are controllable; their deformation is controlled by controlling the compressive force on the wires 13, thereby controlling the equivalent diameter of the wire channels 131. If the air passage of the smoke generator 100 is divided into radial sections, the size of the wire gap 1A can be controlled by controlling the outer diameter of the adjacent wires 13 in different sections, and / or the equivalent inner diameter of the air passage in different sections can be controlled by controlling the equivalent diameter of the wire channel 131 in different sections, so as to meet the need for local adjustment of suction resistance, air intake, etc. due to the different smoke output caused by uneven heating of the smoke generator 100.

[0158] It should be noted that when the compressive force on the wire 13 due to being bundled is insufficient to deform the wire 13, the wire channel 131 is the channel formed when the smoke strip 12 is twisted to form the wire 13; when the compressive force on the wire 13 due to being bundled is sufficient to deform the wire 13, the wire channel 131 is the remaining channel after the wire 13 is deformed. It can be understood that the greater the compressive force between adjacent wires 13, the more complex the shape of the wire channel 131, and the smaller the equivalent diameter of the wire channel 131.

[0159] It should also be noted that when the compressive force on the bundled wires 13 is insufficient to deform the wires 13, the wires 13 can be at least one of circular and spindle shapes in the cross section perpendicular to the axis of the smoke-generating body 100; when the compressive force on the bundled wires 13 is sufficient to deform the wires 13, each wire 13 will have a different shape due to different deformation in the cross section perpendicular to the axis of the smoke-generating body 100, and the deformation of each wire 13 is random, that is, the deformation of the wires 13 is different even if the number of wires 13, the initial shape of each wire 13, and the equivalent diameter of the bundled wires 13 remain unchanged.

[0160] It should also be noted that the compressive force on wire 13 can be generated during the bundling process or during the shaping process of composite strand 1.

[0161] It should also be noted that when wire 13 is manufactured using a twisting process, the surface of wire 13 is not smooth due to the presence of the concave-convex structure 130. (When multiple wires 13 are parallel, the gap 1A between the wires is not a completely flat and smooth channel, but has a concave-convex buffer space, which is also conducive to cooling when airflow passes through.) This structural feature of wire 13, combined with the aforementioned gap 1A between the wires, constitutes a better airflow speed control method.

[0162] It should be noted that in other embodiments, the smoke-generating body 100 may not have a second shaping layer 17, and the bundle of wires 13 formed by multiple wires 13 can be externally bundled or shaped by incorporating adhesive, etc.

[0163] External binding and shaping: The outer periphery of the wire bundle 13 is bound with one or more binding threads to achieve shaping. Alternatively, there is another implementation method, in which each wire 13 is bound by one or more binding threads inserted into the wire bundle 13 so that the binding threads are not exposed, or by a binding structure in which the same binding thread is partially inserted into the wire 13 and partially exposed outside the wire 13, such as by sewing, to achieve shaping.

[0164] Adhesive application for shaping: Adhesive is applied to at least the surface of the wires 13 before or after bundling, through spraying, soaking, or coating, so that the wires 13 can bond together upon contact, thereby shaping the bundled smoke body 100. The bonding can be done at one end of the smoke body 100, leaving the middle section with a loose structure. Alternatively, the entire length of the smoke body 100 can be bonded while maintaining effective porosity and suction resistance. Furthermore, the adhesive hardens relatively after drying, which helps to shape the winding state of the wires 13 and provides support for the smoke body 100.

[0165] It should also be noted that when the binding thread is used to bind the outer periphery of the wire bundle 13 for shaping, the binding thread can be made of the same material as the wire 13, the only difference being the length of the binding thread and the wire 13. The binding thread can be a metal wire or a fiber thread. When the binding thread is inserted into the wire bundle 13 to bind each wire 13 or partially inserted into the wire 13 through the same binding thread, the binding thread can be a metal wire or a fiber thread. The fiber thread can be various natural fibers (plant fibers and mineral fibers) or chemical fibers (man-made fibers, synthetic fibers, and inorganic fibers) that do not contain nicotine. Suitable natural fibers include plant fibers and mineral fibers that can withstand temperatures up to 250°C. On the one hand, it can play a role in bundling and shaping, eliminating the need for a second shaping layer 17 made of film or paper. On the other hand, the binding thread can be used to add fragrance and achieve a unique flavor. Moreover, this structure allows for more airflow gaps on the outer surface of the smoke-generating body 100, resulting in a relatively low outer surface temperature and less thermal impact on the external smoke tube.

[0166] It should also be noted that the binding material is not limited to binding material. The binding material can also adopt one of the following shapes: strip, sheet, mesh, block, tube, and ball.

[0167] The second shaping layer 17 can be made of aluminum foil 171 and pine paper 173. After shaping, the outer perimeter is circular. The aluminum foil 171 has a certain strength, which is conducive to shaping and ensuring roundness.

[0168] As shown in Figures 17 and 18, the smoke generator 100 does not contain heating elements, and the wires 13 are arranged longitudinally in an orderly manner along the central axis of the smoke generator 100. This configuration is suitable for inserting needle-shaped or sheet-shaped heating elements into the central region of the smoke generator 100 for central heating, or for using annular heating elements to perform circumferential heating of the smoke generator 100 from the periphery. In addition, since there are wire channels 131 in the wires 13, the insertion resistance can be reduced by the deformation of the wires 13 when the needle-shaped or sheet-shaped heating elements are inserted into the smoke generator 100.

[0169] The difference between the embodiment shown in Figure 19 and the embodiment shown in Figure 18 is that, as shown in Figures 17 and 19, multiple wires 13 are twisted together to give the wires 13 an overall twisted shape. With this overall twist, on the one hand, the wires 13 are less likely to fall off during processing; on the other hand, the wire gaps 1A and wire channels 131 are no longer straight but spiral-shaped, extending the length of the airflow path, enhancing the effect of heat convection heat transfer, and contributing to the reduction of aerosol temperature.

[0170] It should be noted that the twisting direction of the smoke-generating strip 12 to form the wire 13 is opposite to the twisting direction of the multiple wires 13 twisted together (i.e., following the principle of "alternating twisting direction"), in order to achieve dynamic mechanical balance and prevent twisting. Specifically, one of the twisting directions of the smoke-generating strip 12 to form the wire 13 and the twisting direction of the multiple wires 13 twisted together is "Z twist" and the other is "S twist". "Z twist" is usually defined as the rotation direction of the twisting stator being clockwise; "S twist" is usually defined as the rotation direction of the twisting stator being counterclockwise.

[0171] The difference between the embodiment shown in Figure 20 and the embodiment shown in Figure 18 is that, as shown in Figures 17 and 20, the smoke generator 100 has a short rope-like structure. This short rope segment has a loose structure, including multiple strands 13 intertwined together. The interweaving of these strands 13 makes them less likely to fall off during processing. Furthermore, the gaps 1A and channels 131 between the strands are no longer straight but spiral-shaped, extending the length of the airflow path. This enhances the effect of heat convection and helps reduce the aerosol temperature.

[0172] The difference between the embodiment shown in Figure 21 and the embodiments shown in Figures 17 and 18 is that, as shown in Figure 21, the smoke generator 100 is provided with a plurality of metal plates 19, which are configured to generate heat by inducing an alternating magnetic field. When the smoke generator 100 is applied to a smoking device that can generate an alternating magnetic field, the metal plates 19 act as heating elements to heat the smoke generator 100.

[0173] The difference between the embodiment shown in Figure 22 and the embodiments shown in Figures 17 to 20 is that at least a portion of the wires 13 in the smoke-generating body 100 are formed into composite strands 1 as shown in Figures 7 to 10.

[0174] The difference between the embodiments shown in Figures 23 to 26 and the embodiments shown in Figures 17 to 20 is that, as shown in Figures 22 to 26, a sensor 15 is provided inside the smoke-generating body 100.

[0175] As shown in Figure 23, in some embodiments, the sensor 15 is in contact with the wire 13, and the sensor 15 and the wire 13 extend in the same direction. That is, the sensor 15 can be bundled with multiple wires 13, or it can be twisted together with multiple wires 13, or it can be intertwined with the wires 13. In this case, a wire gap 1A is also formed between the sensor 15 and the wire 13.

[0176] For example, the interior of the smoke generator 100 has a short rope-like structure, which is a fluffy structure including multiple strands of receptors 15 and multiple strands of wire 13 that are intertwined and woven together.

[0177] It should be noted that in some other embodiments, the second shaping layer 17 may not be provided. The overall shaping of the rope may be achieved by external binding, or by incorporating adhesive or the rope itself. Regarding the rope itself: the multiple strands of rope may be shaped by twisting at least one strand together with each other.

[0178] 1. External binding and shaping: The smoke-generating body 100 is bound with single or multiple strands of thread to achieve shaping. Alternatively, there is another implementation method, in which single or multiple strands of thread are inserted into each rope inside the smoke-generating body 100 for binding, so that the thread used for binding is not exposed, or binding is achieved through an interlacing structure in which the same thread is partially inserted into the rope and partially exposed outside the rope, such as sewing, to achieve shaping.

[0179] 2. Adhesive Application for Shaping: Adhesive is applied to at least the surface of the yarn before or after weaving through spraying, soaking, or coating. This allows the yarns to bond upon contact, thus shaping the woven smoke generator. Bonding can be done at either end of the smoke generator, leaving the middle section with a loose structure. Alternatively, the entire length of the smoke generator can be bonded while maintaining effective porosity and suction resistance. The adhesive hardens after drying, further aiding in shaping the yarn winding and supporting the smoke generator.

[0180] 3. Shaping by the thread itself: At least one thread is pulled out from each of the adjacent ropes in the smoke-generating body 100 and intertwined with each other, so that at least some of the threads between the adjacent ropes are partially intertwined, thereby limiting the position of the adjacent ropes. This process is repeated to achieve overall shaping, which can be done by hand or by textile technology.

[0181] In other applications, the second shaping layer 17 possesses certain mechanical strength and excellent high-temperature stability. Besides using various plant fiber-based ordinary paper and cigarette paper, it can also be made of inorganic fiber paper such as ceramic paper or glassine paper, and various films such as polytetrafluoroethylene film and aluminum foil. This is to achieve better adhesion and easier cutting.

[0182] In this embodiment, the sensor 15 in the smoke-generating body 100 can be configured as a single metal wire, i.e., a monofilament structure; or it can include multiple metal wires, i.e., a multifilament structure.

[0183] To facilitate cutting the sensor 15 and achieve a more uniform distribution within the smoke-generating body 100, more and finer metal wires can be used in the sensor 15. For example, 50 strands of ultra-fine magnetic metal wire with an equal diameter of 0.05 mm can be used as heating elements. However, excessive heating elements are difficult to cut during sizing and can easily lead to over-carbonization or even scorching of the smoke-generating body 100 during smoking applications. Therefore, considering economic cost and manufacturability while achieving the necessary eddy current heating effect, this application defines the number of strands of metal wire in the sensor 15 as between 2 and 100, with the diameter of a single metal wire set between 0.01 and 1 mm.

[0184] When the sensor 15 is configured as a single metal wire, the wire 13 can be configured as a single wire 13, a composite strand 1 formed by at least two wires 13, or a composite strand 1 formed by the wire 13 and the sensor 15. Those skilled in the art can also design the constituent units of the smoke generator 100 and the arrangement of its internal strands according to parameters such as flue gas flow rate, heating efficiency, and target customer requirements; these will not be listed or detailed here.

[0185] A single metal wire is a physical unit whose material composition is one of a single metal, a single alloy, or a composite metal.

[0186] In some configurations, the metal wires in the smoke generator 100 are made of the same material and are magnetic. Examples of single-element metal wires in this case include iron (Fe) wire, nickel (Ni) wire, and cobalt (Co) wire; examples of single-alloy wires include various magnetic stainless steel wires (such as ferritic stainless steel, martensitic stainless steel, and certain cold-worked austenitic stainless steel), various soft magnetic alloys (such as permalloy, iron-based amorphous alloy, cobalt-based amorphous alloy, iron-based nanocrystalline alloy, iron-silicon-aluminum alloy, Invar alloy, constant expansion alloy) wires, and Kovar alloy wires, etc.; composite metal wires contain two or more metal materials, of which at least one is magnetic material, and composite refers to being combined together by means of rolling, electroplating, electroless plating, sputtering, welding, cladding, and coating.

[0187] In other configurations, the smoke generator 100 contains metal wires of different materials, at least one of which is magnetic. A primary function of the magnetic metal wires contained in the sensor 15 in this application is as a magnetic induction heating element, i.e., under the excitation of a high-frequency alternating magnetic field, it generates a strong eddy current heating effect.

[0188] In some embodiments, the sensor 15 has a dual-wire structure, consisting of two magnetic metal wires of different materials twisted together. One wire is a stainless steel 410 (SUS410) round wire with a diameter of 0.12 mm; the other wire is a nickel (Ni) round wire with a diameter of 0.08 mm.

[0189] Based on this, other application scenarios and design parameters are derived as follows:

[0190] When the sensor 15 contains multiple metal wires, it can be called a multi-wire structure, such as a composite metal strand made of multiple metals wound together. There are three basic combinations of composite metal strands: magnetic metal wires wound with magnetic metal wires, magnetic metal wires wound with non-magnetic metal wires, and non-magnetic metal wires wound with non-magnetic metal wires. Regardless of the combination, at least two magnetic metal wires are required in the magnetic smoke generator. The magnetic metal wires can be made of the aforementioned magnetic materials. Non-magnetic metal wires include copper (Cu) wire, silver (Ag) wire, aluminum (Al) wire, titanium (Ti) wire, chromium (Cr) wire, and various highly ductile alloys (such as nickel-chromium alloys, silver-copper alloys, and aluminum alloys), all of which can withstand temperatures up to 500°C.

[0191] When the sensor 15 is configured in the form of composite metal strands, the configuration of the wire 13 can be a single wire 13, a composite strand 1 formed by at least two wires 13, or a composite strand 1 formed by the wire 13 and the sensor 15. Similarly, those skilled in the art can design the arrangement and combination of strands according to parameters such as flue gas flow rate, heating efficiency, and target customer needs, which will not be listed and described in detail here.

[0192] The difference between the embodiment shown in Figure 24 and the embodiment shown in Figure 23 is that, as shown in Figure 24, at least a portion of the wires 13 in the smoke-generating body 100 and the sensor 15 form a composite strand 1 as shown in Figure 15; or, at least a portion of the wires 13 in the smoke-generating body 100 and the sensor 15 form a composite strand 1 as shown in Figures 11 to 13.

[0193] The difference between the embodiment shown in Figure 25 and the embodiment shown in Figure 23 is that, as shown in Figure 25, at least a portion of the wire 13 in the smoke generator 100 forms a composite strand 1 as shown in Figure 14 with the sensor 15.

[0194] In the embodiments shown in Figures 24 and 25, the sensor 15 is a single metal wire, meaning that the single wire 13 and the sensor 15 are in a single yarn and single filament configuration. The metal wire can be a 0.2mm diameter SUS 420 stainless steel round wire, which is a martensitic stainless steel and has magnetic properties. When the smoke generator 100 is twisted as a whole or has a short rope-like structure, on the one hand, the wire 13 is less likely to fall off during processing; on the other hand, the gap 1A between the wires is no longer straight but spiral-shaped, extending the length of the airflow path, which can enhance the effect of heat convection heat transfer and help reduce the aerosol temperature.

[0195] The sensor 15 is magnetic. When the cartridge is used in conjunction with the electromagnetic smoking device, it couples with the high-frequency alternating electromagnetic field generated in the device, rapidly increasing its temperature through eddy current heating, and then heating the adjacent wire 13. Therefore, the smoke generator 100 in this embodiment is a magnetic smoke generator, with its sensor 15 (heating element) discretely distributed throughout the smoke generator 100, which has advantages such as easy cutting during processing and uniform heating and carbonization during operation.

[0196] Some applications derived from this implementation method include:

[0197] The sensor 15 is a physical unit, and its material composition is one of a single metal, a single alloy, or a composite metal. Examples of single metal wires include iron (Fe) wire, nickel (Ni) wire, and cobalt (Co) wire; examples of single alloy wires include various magnetic stainless steel wires (such as ferritic stainless steel, martensitic stainless steel, and some cold-worked austenitic stainless steel), various soft magnetic alloys (such as permalloy, iron-based amorphous alloy, cobalt-based amorphous alloy, iron-based nanocrystalline alloy, iron-silicon-aluminum alloy, Invar alloy, constant expansion alloy), and Kovar alloy wire, etc.; the sensor 15 is a composite metal wire, which contains two or more metal materials, including at least one magnetic material. Composite means that they are combined together by means of rolling, electroplating, electroless plating, sputtering, welding, cladding, and coating.

[0198] In other applications, to facilitate cutting the sensor 15 and achieve a more uniform distribution within the magnetic smoke generator 100, the sensor 15 can be composed of more and finer metal wires, such as 50 strands of equal-sized ultrafine magnetic metal wires with a diameter of 0.05 mm as the heating element. However, excessive heating elements are difficult to cut during sizing and can easily lead to over-carbonization or even scorching of the magnetic smoke generator 100 during smoking applications. Therefore, considering economic cost and manufacturability while achieving the necessary eddy current heating effect, this application sets the diameter of a single metal wire in the sensor 15 of the cartridge to between 0.01 and 1 mm.

[0199] In some other embodiments, the sensor 15 has a dual-wire structure, consisting of two magnetic metal wires of different materials twisted together. One wire is a stainless steel 410 (SUS410) round wire with a diameter of 0.12 mm; the other wire is a nickel (Ni) round wire with a diameter of 0.08 mm.

[0200] In other application scenarios and design parameters, the following are derived:

[0201] When the sensor 15 contains multiple metal wires, it can be called a multi-wire structure, such as a composite metal strand made of multiple metals wound together. There are three basic combinations of composite metal strands: magnetic metal wires wound with magnetic metal wires, magnetic metal wires wound with non-magnetic metal wires, and non-magnetic metal wires wound with non-magnetic metal wires. Regardless of the combination, at least two magnetic metal wires are required in the magnetic smoke generator. The magnetic metal wires can be made of the aforementioned magnetic materials. Non-magnetic metal wires include copper (Cu) wire, silver (Ag) wire, aluminum (Al) wire, titanium (Ti) wire, chromium (Cr) wire, and various highly ductile alloys (such as nickel-chromium alloys, silver-copper alloys, and aluminum alloys), all of which can withstand temperatures up to 500°C.

[0202] In some applications, the basic constituent units of the smoke generator 100 can be configured in various easily manufactured combinations. For example, as shown in the embodiment of FIG26, the difference between the embodiment shown in FIG26 and the embodiment shown in FIG23 is that the smoke generator 100 includes wires 13, sensors 15, and composite strands 1. The composite strands 1 can be any composite strands shown in FIG7-16. The sensors 15 can be interwoven with adjacent wires 13, and the wires 13 interwoven with the sensors can also be wires 13 within the composite strands 1, i.e., the sensors 15 are interwoven with the composite strands 1. Therefore, the wire 13, the sensor 15, and the composite strand 1, as constituent units of the smoke generator 100, also have surface irregularities that facilitate airflow and cooling. Encasing the sensor 15 increases strength and prevents it from becoming entangled around the smoke generator 100 or coming into contact with the second shaping layer 17 (which typically contains paper), thus avoiding significant thermal impact on the second shaping layer 17 (which usually contains paper) and the external smoke tube, which could lead to a papery or glue-like smell. The smoke generator 100 can also have other constituent unit configurations. A reasonable configuration requires obtaining an optimized smoke generator 100 with high porosity (the ratio of the open area within the cross-section to the overall cross-sectional area), good roundness, a symmetrical and uniform structure, and the inclusion of the necessary sensor 15.

[0203] The configuration of the basic constituent units of the smoke body 100 has various effects resulting from a combination of easy-to-manufacture components: (1) Some configurations are designed to improve manufacturability. On the one hand, they increase longitudinal tensile strength because some constituent units have low strength, for example, the wire 13 has low strength. Therefore, in this application, a blending method is used to reduce breakage in textiles, etc. On the other hand, it ensures that the transverse cutting difficulty is reduced when cutting the smoke body 100. Because thicker knots or bundles and overly concentrated wire distribution will significantly increase the transverse cutting force, increase the difficulty in the small-segment cutting process of the smoke body 100 and accelerate the wear of the tool. Therefore, in this application, the constituent units of the smoke body 100 are configured with a smaller equivalent diameter, a narrower equivalent diameter distribution range, and a finer and more discretely distributed wire to achieve this purpose. (2) Some configurations are designed to improve the stability of the smoke-generating body 100 structure. Various sizes and blending methods are used to make the physical arrangement inside the smoke-generating body 100 more uniform and its outer perimeter more rounded. This reduces the difficulty of subsequent cartridge splicing and improves the aesthetics of the cartridge. Especially during the rope winding or bundle shaping process, various different units with a certain degree of appropriate difference in equivalent diameter are required to make the rope or bundle fuller and the internal space accommodate more fiber filaments and metal wires, making the structure more stable during processing and ensuring the consistency of shape and gap ratio. (3) Some configurations are designed to build a stable and uniform airway. Various blending methods are used to obtain the loosest possible structure and to build the gaps between units that are distributed as evenly as possible. This design, along with the loose internal structure of the wire 13 and the metal wire itself, makes the smoke-generating body have a smaller suction resistance. At the same time, when heated, the physical deformation trend of the internal units of the smoke-generating body 100 is coordinated, thereby keeping the airway stable and ultimately providing users with a high-quality user experience. (4) Some configurations are designed to achieve more uniform heating and final carbonization effect. In particular, the metal wires that function as heating elements are refined and evenly distributed, which makes the heating of the smoke-generating body 100 more uniform, the smoke output speed faster, the smoke volume fuller, and carbonization more uniform, improving the utilization rate of effective ingredients and reducing the phenomenon of excessive carbonization caused by local overheating, resulting in scorching or even the release of harmful substances. (5) Some configurations are designed to reduce the thermal impact on the shaping layer of the smoke-generating body and the outer paper tube of the cartridge. Therefore, in some applications, the heating element metal wires are first wrapped with wire 13 and then used as a bundle or rope unit. This can reduce the thermal impact on the shaping layer and the outer paper tube of the cartridge.

[0204] The difference between the embodiment shown in Figure 27 and the embodiment shown in Figure 23 is that, as shown in Figure 26, at least a portion of the wires 13 in the smoke-generating body 100 are formed into a composite strand 1 as shown in Figure 16.

[0205] The difference between the embodiment shown in Figure 28 and the embodiment shown in Figure 23 is that, as shown in Figure 27, at least a portion of the wires 13 in the smoke-generating body 100 are formed into composite strands 1 as shown in Figures 7 to 10.

[0206] It should be noted that in the above embodiments, the wires 13 in the composite strand 1 or smoke generator 100 shown in the above figures are all circular and each wire 13 has the same or substantially the same diameter. This is to simplify the shape and structure of the wires 13 in the figures, and should not be construed as meaning that the wires 13 in the composite strand 1 or smoke generator 100 of this disclosure can only be circular and each wire 13 has the same or substantially the same diameter. For example, when the wires 13 are bundled and the compressive force they receive is insufficient to deform the wires 13, when perpendicular to the composite strand 1 or smoke generator 100... On the cross section of the axis of the composite strand 1, the wire 13 can be at least one of circular and spindle shapes; when the wire 13 is bundled and subjected to sufficient compressive force to deform the wire 13, on the cross section perpendicular to the axis of the composite strand 1, each wire 13 will have a different shape due to different deformation, and the deformation of each wire 13 is random, that is, under the condition that the number of wires 13, the initial shape of each wire 13, and the equivalent diameter after multiple wires 13 are bundled remain unchanged, the deformation of the wire 13 is not the same.

[0207] In the above embodiments, the number of wires 13 is only an example, and the number of wires 13 in this disclosure is not limited to this.

[0208] In some embodiments, preferably, the number of wires 13 is 20 to 40.

[0209] For example, the number of wires 13 can be 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, or 40, etc. This disclosure does not impose a specific limitation in this regard.

[0210] More preferably, the number of wires 13 is 25-35.

[0211] It should be noted that in the above embodiments, the composite strands 1 can be intertwined, or multiple composite strands 1 can be twisted as a whole, or multiple composite strands 1 can be stacked in parallel.

[0212] In the above embodiment, the volume percentage of wire 13 in the smoke-generating body 100 exceeds 40%. By setting the volume percentage of wire 13 in the smoke-generating body 100 to exceed 40%, the smoke-generating body 100 can have a sufficient amount of smoke.

[0213] In the above embodiment, the axial length of the smoke-generating body 100 is 11±1mm; the diameter of the smoke-generating body 100 is 5±1mm.

[0214] In the above embodiments, the sensor 15 can be a single metal wire or can be formed by multiple metal wires.

[0215] Optionally, the number of metal wires can be 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10. It is understood that the number of metal wires is not limited to the values ​​mentioned above. This disclosure does not impose any specific limitations in this regard.

[0216] Alternatively, multiple metal wires can be twisted or interwoven to form a braided structure.

[0217] To verify the magnetic behavior of the sensor 15 during its application from room temperature to a stable operating temperature, this application tested the magnetization intensity M as a function of temperature (MT curve) and the magnetization rate of change dM / dT as a function of temperature T for the sensor 15 made of iron-nickel alloy 4J29 in the temperature range of 20-573℃, as shown in Figure 29. Figure 29 is a schematic diagram of the magnetization temperature curve of a sensor made of iron-nickel alloy 4J29 provided in an exemplary embodiment of this disclosure. The curve shows that before 400℃, the sensor 15 has a high and stable permeability, with a magnetization intensity as high as 50 emu / g. After 400℃, its permeability drops rapidly, reaching 0 at 450℃. Based on the peak and valley of dM / dT-T, its Curie temperature Tc can be determined to be 450℃. This magnetic behavior has many valuable aspects.

[0218] (1) Ensure strong and stable coupling: The reasonable carbonization temperature of common aerosol matrix is ​​around 350℃, while the temperature drop caused by taking a puff is usually in the range of 10-50℃. The sensor 15 has a high and stable magnetic permeability before 400℃. Therefore, when the aerosol generation system is working normally, it can always generate a strong and stable coupling with the high-frequency alternating electromagnetic field generated by the smoking device.

[0219] (2) As a reference for setting the stable operating temperature of the aerosol generation system: During the initial preheating stage of the system, the heating is continued, so that the sensor 15 continues to rise to more than 400°C, for example, 410°C. The permeability of the sensor 15 shows a clear inflection point at 400°C. The system finds the current inflection point Im corresponding to the temperature inflection point by the obvious change in the power supply current Idc in the circuit before and after the inflection point. Thus, the inflection point temperature Tm can be determined to be 400°C. If the expected stable operating temperature Tw is 350°C, then the stable operating current Iw corresponding to 350°C is deduced backward from this current inflection point, so as to set the stable operating temperature Tw to 350°C.

[0220] (3) Non-contact sensorless temperature measurement: Based on the above description, the temperature of the sensor 15 corresponding to each working current Idc can be calibrated based on this magnetic change behavior and experimental data to achieve real-time temperature measurement, without the need to use physical sensors in the system.

[0221] (4) Exclusivity of cartridges and devices: As an ecosystem, when cartridges and devices are configured to match each other based on the parameters of the sensor 15, multiple target thresholds can be set to ensure that the combination of cartridges (including specific sensor 15 configurations) and devices (including specific control configurations) is exclusive. That is, a certain type of cartridge can only work normally in a certain type of device, and similarly, a certain type of device can only use a certain type of cartridge. This achieves the purpose of anti-counterfeiting identification and prevents safety accidents caused by the use of incorrect cartridges or incorrect devices.

[0222] (5) Safety Protection: Two modes can be configured, including active protection, passive protection, or a combination of both. Active protection, for example, involves a significant decrease in magnetism until the sensor 15 loses its magnetism when the temperature of sensor 15 abnormally exceeds 410°C. Consequently, the coupling strength decreases significantly until coupling is lost, meaning the power input is significantly reduced until it reaches the pipe wall. Passive protection, for example, involves setting a threshold temperature Ts for Idc in a specific control configuration for the smoking device. When the temperature of sensor 15 exceeds the threshold temperature Ts, the system reduces or cuts off the power input.

[0223] According to a sixth aspect of this disclosure, a tobacco cartridge is provided, which includes the smoke-generating body 100 described above, and the tobacco cartridge has all the beneficial effects of the smoke-generating body 100 described above, which will not be repeated here.

[0224] As shown in Figure 30, in some embodiments, the e-cigarette cartridge includes a smoke-generating body 100, a bottom plug 200, a cooling component 300, a filter tip 400, and a wrapping component 500. The bottom plug 200 is located upstream of the smoke-generating body 100, the cooling component 300 is located downstream of the smoke-generating body 100, the filter tip 400 is located downstream of the cooling component 300, and the wrapping component 500 covers the bottom plug 200, the smoke-generating body 100, the cooling component 300, and the filter tip 400.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
