[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, combined 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 been heated without burning to produce the original flavor of tobacco. 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] To achieve the above objectives, according to a first aspect of this application, a wire is provided for use in a smoke-generating body, 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, and the twist of the wire is between a first preset value and a second preset value.

[0006] Optionally, one of the following conditions must be met: the first preset value is not greater than 45 twists / m, and the second preset value is not less than 50 twists / m; 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; the twist of the wire is between 40 twists / m and 60 twists / m; or the twist of the wire is between 45 twists / m and 50 twists / m.

[0007] Optionally, at least one of the following conditions must be met: the tensile strength of the smoke-generating strip is 7 N / m. 2 -10N / m 2 Between; the tensile strength of the wire is not less than 15 N / m 2 Between; the ratio of the tensile strength of the wire to the tensile strength of the smoke strip is above 1.5; the wire contains short fibers, the length of the short fibers is not greater than 38mm, and the mass proportion of short fibers in the wire is not less than 50%.

[0008] Optionally, the wire includes a first part and a second part arranged opposite to each other, the first part and the second part being connected end to end in sequence, and the connection between the first part and the second part having an acute angle.

[0009] According to a second aspect of this application, a composite strand is provided, comprising at least two of the aforementioned strands, wherein the at least two strands are in contact with each other and each strand extends along a predetermined direction.

[0010] According to a third aspect of this application, a composite strand wire is provided, comprising: the aforementioned wire; a sensor, wherein a smoke-generating strip is twisted and wound around the sensor.

[0011] According to a fourth aspect of this application, a composite strand is provided, comprising: the aforementioned strand; a sensor, wherein one of the sensor and the strand is wound around the periphery of the other, or the sensor and the strand are twisted together.

[0012] According to a fifth aspect of this application, a smoke generator is provided, comprising at least one of the following: a plurality of the above-described wires; or at least one of the above-described composite strands.

[0013] Optionally, multiple threads are woven together to form a smoke generator.

[0014] Optionally, the smoke generator also includes a metal plate configured to generate heat using an alternating magnetic field.

[0015] Optionally, the number of wires is 20-40.

[0016] According to a sixth aspect of this application, a tobacco cartridge is also provided, the tobacco cartridge comprising the smoke-generating body of any of the above.

[0017] In the wire of this application embodiment, a smoke-generating strip with a tensile strength of not more than 10 N / m 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 wire formed by twisting 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 wire formed by twisting the smoke-generating strip a higher tensile strength than the smoke-generating strip.

[0023] 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.

[0024] Reconstituted tobacco sheet, also known as recycled tobacco or homogenized tobacco, is a thin, regenerated product made primarily from tobacco leaves, stems, and dust, combined 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 packaged in rolled 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… 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. Currently, the mainstream Philip Morris (PMI) manufactures smoke bodies using tobacco sheets. This is achieved by embossing the tobacco sheets to create continuous indentations, and then using a winding machine to roll the tobacco sheets into a cylindrical shape, thus enabling 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 rolled into smoke bodies, the small pieces formed by embossing and winding are connected, hindering the passage of air.

[0025] One of the objectives of this invention is to enable high-speed production of tobacco strips for tobacco smoke production. 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-tier high-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 smoke production 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 smoke production threads are required, even higher tensile strength is needed, especially for textile-type tobacco smoke production threads that require weaving. The tensile strength of the threads must meet the minimum tensile strength requirements for textile yarns.

[0026] 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.

[0027] According to the first aspect of this application, referring to Figures 1 to 6 The present disclosure provides a wire 13, which is configured to be formed by twisting a smoke-generating strip 12, wherein the tensile strength of the smoke-generating strip 12 is not greater than 10 N / m, and the twist of the wire 13 is between a first preset value and a second preset value.

[0028] Optionally, the second preset value is greater than the first preset value.

[0029] 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.

[0030] The technical solution disclosed herein involves twisting a smoke-generating strip 12 with a tensile strength not exceeding 10 N / m to form a wire 13, wherein 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 directly breaking, 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 not greater than 10 N / m, and the twist of the wire 13 is between the first and second preset values, the untwisting stress of the wire 13 itself is very small, thus the wire 13 can maintain or substantially maintain the shape after twisting the smoke-generating strip 12.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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 invention defines the boiling point temperature range as 180-350°C.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] like Figure 3 and Figure 6As shown, 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 along the twisting axis X, and 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.

[0040] 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: 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. 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. 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.

[0041] In some embodiments, the first preset value is not greater than 45 twists / m, and the second preset value is not less than 50 twists / m.

[0042] 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, 26 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, or 16 twists / m. The first preset value can be 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.

[0043] 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, 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, or 84 twists / m. The values ​​are 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.

[0044] In some embodiments, 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.

[0045] like Figure 3 and Figure 4As shown, 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.

[0046] 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.

[0047] 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.

[0048] In some embodiments, the twist of the wire 13 is between 45 twists / m and 50 twists / m.

[0049] 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.

[0050] Optionally, the tensile strength of the smoke-generating strip 12 can be 1 N / m. 2 2N / m 2 3N / m 2 4N / m 2 5N / m 2 6N / m 2 7N / m 2 8N / m2 9N / m 2 or 10N / m 2 wait.

[0051] Preferably, the tensile strength of the smoke-generating strip 12 is 7 N / m. 2 -10N / m 2 between.

[0052] 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.

[0053] In some embodiments, the tensile strength of wire 13 is not less than 15 N / m. 2 between.

[0054] 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 / m 2 28N / m 2 29N / m 2 30N / m 2 31N / m 2 32N / m2 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.

[0055] In some embodiments, the ratio of the tensile strength of the wire 13 to the tensile strength of the smoke strip 12 is greater than 1.5.

[0056] Optionally, the ratio of the tensile strength of the wire 13 to the tensile strength of the smoke strip 12 may 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 may also be between the two values ​​mentioned above. This disclosure does not impose specific limitations in this regard.

[0057] 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.

[0058] like Figures 1 to 3 as well as Figure 6 As shown, 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.

[0059] In some embodiments, the ratio of L1 to L2 is not less than 10.

[0060] 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.

[0061] In some embodiments, the ratio of L2 to L3 is greater than 1.

[0062] 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.

[0063] In some embodiments, the thickness L3 of the smoke-generating strip 12 is between 0.01 mm and 0.50 mm.

[0064] 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.

[0065] like Figure 4 As shown, 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.

[0066] 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, etc. 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.

[0067] 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.

[0068] 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.

[0069] like Figure 5 As shown, 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 being connected end to end, and the connection point of the first portion 133 and the second portion 135 having 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 wider. 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 after the smoke strip 12 is twisted.

[0070] This disclosure also provides a method for preparing a smoke-generating line, comprising: Form long strips, cut the smoking sheet into strips and roll them into long strip coils; Twisting: Long strips are twisted to form smoke-generating wires.

[0071] The tensile strength of the long strip is no greater than 10 N / m, and the twist is between the first and second preset values.

[0072] 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.

[0073] like Figure 31 As shown, this disclosure also provides an apparatus for preparing a smoke-generating line, comprising: 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; Twisting device 700 is used to twist the long strip released from the long strip reel to form a smoke-generating wire; 800 winding device, winding and smoke-generating line; 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.

[0074] 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.

[0075] According to the second aspect of this disclosure, such as Figures 7 to 10 As shown, 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 in this disclosure.

[0076] In embodiments of this disclosure, the composite yarn 1 is formed by a textile process.

[0077] like Figure 7 and Figure 8 As shown, 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.

[0078] 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.

[0079] 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, the wires 13 will have different shapes in the cross section perpendicular to the axis of the composite strand 1 due to different deformations, 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.

[0080] 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.

[0081] 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.

[0082] like Figure 7 As shown, for example, the number of wires 13 is 4.

[0083] 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.

[0084] Figure 9 The illustrated embodiments and Figure 8 The difference between the embodiments shown is that: Figure 7 and Figure 9As shown, the composite strand 1 is twisted and twisted as a whole to make the wire 13 have an overall twisted shape. Under this overall twist, on the one hand, the wire 13 is not easy to fall off during the process, and on the other hand, the wire gap 1A and wire channel 131 are no longer straight, but spiral, which extends the length of the airflow path, enhances the effect of heat convection heat transfer, and helps to reduce the temperature of the aerosol.

[0085] 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.

[0086] like Figure 10 The illustrated embodiments and Figure 8 The difference between the embodiments shown is that: Figure 7 and Figure 10 As shown, the composite strand 1 has a short rope-like structure. This short rope segment has a loose structure and includes multiple strands 13 intertwined and woven together. The multiple strands 13 are intertwined and woven together, which makes it less likely for the strands 13 to fall off during processing. Furthermore, the gaps 1A and the strand channels 131 are no longer straight, but rather the intertwining of the strands 13 extends the length of the airflow path, which can enhance the effect of heat convection and help reduce the aerosol temperature.

[0087] 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 by incorporating adhesive, etc. External binding and shaping: The outer periphery of the wire bundle 13 is bound with one or more binding threads to achieve shaping. Alternatively, in another embodiment, 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 binding is achieved by a cross-linking 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 or threading, to achieve shaping. 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.

[0088] 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.

[0089] 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.

[0090] According to the third aspect of this application, such as Figures 11 to 13As shown, a composite strand 1 is provided, comprising 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 0.2mm diameter stainless steel SUS 420 round wire, which is a martensitic stainless steel and possesses magnetic properties. Because 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 not by controlling the twist degree when the smoke-generating strip 12 is twisted to form the wire 13. Thus, in addition to this effective effect, the composite strand 1 possesses 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. And when the tensile strength of the wire 13 is the same, the required twist degree is lower when the wire 13 is directly twisted onto the sensor 15. At the same time, the sensor 15 can rapidly increase its temperature through eddy current heating in an alternating magnetic field. In this disclosure, as Figures 11 to 13 In the embodiment shown, the composite strand 1 is cylindrical in shape.

[0091] In this disclosure, as Figures 11 to 13 In the illustrated embodiment, 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 the multiple composite strands 1 in this embodiment are applied to the smoke generator 100, 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.

[0092] Some applications derived from this embodiment include: 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.

[0093] 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. Therefore, considering economic cost and manufacturability while achieving the necessary eddy current heating effect, this invention sets the diameter of a single metal wire in the sensor 15 of the tobacco cartridge between 0.01 and 1 mm.

[0094] 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.

[0095] In other application scenarios and design parameters, the following are derived: 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.

[0096] This disclosure also provides a method for preparing composite strands, including: Form long strips by cutting the smoke-generating sheets into strips and rolling them into long strip coils; 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.

[0097] The tensile strength of the long strip is no greater than 10 N / m, and the twist is between the first and second preset values.

[0098] 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.

[0099] like Figure 32 As shown, this disclosure also provides an apparatus for preparing composite strands, comprising: 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. 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; 800 winding device for winding composite strands; 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.

[0100] 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.

[0101] According to the fourth aspect of this application, such as Figures 14 to 16 As shown, a composite strand 1 is provided, comprising a wire 13 and a sensor 15, wherein one of the sensor 15 and the wire 13 is wound around the outer periphery of the other, or the sensor 15 and the wire 13 are twisted together. This composite strand 1 possesses all the other beneficial effects of the aforementioned wire 13, which will not be elaborated further herein.

[0102] Figure 14 The illustrated embodiments and Figure 11-13 The difference between the embodiments shown is that: Figure 14 As shown, the sensor 15 is wound around the outer periphery of the wire 13.

[0103] 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.

[0104] like Figure 15 As shown, in some embodiments, the wire 13 is wound around the outer periphery of the sensor 15.

[0105] 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.

[0106] like Figure 16 As shown, 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.

[0107] 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.

[0108] exist Figures 14 to 16 In the illustrated embodiment, 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.

[0109] 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.

[0110] According to the fifth aspect of this disclosure, such as Figures 17 to 28 As shown, a smoke generator 100 is provided, which includes a plurality of the aforementioned wires 13. The smoke generator 100 has all the beneficial effects of the aforementioned wires 13, which will not be repeated here.

[0111] In the 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.

[0112] like Figure 17 and Figure 18 As shown, 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 in a straight state, i.e., multiple wires 13 forming a wire bundle; it also contains longitudinally straight wire channels 131 and wire gaps 1A, both of which are constructed as part of the air passage of the smoke-generating body 100. Furthermore, the wire gaps 1A are controllable, and the size of the wire gaps 1A is controlled by controlling the outer diameter of adjacent wires 13, thereby controlling the equivalent inner diameter of the air passage; and the wire channels 131 are controllable, and the deformation of the wires 13 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.

[0113] 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.

[0114] 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, the wires 13 will have different shapes in the cross section perpendicular to the axis of the smoke-generating body 100 due to different deformations, 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.

[0115] 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.

[0116] 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.

[0117] It should be noted that in other embodiments, the smoke generator 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. External binding and shaping: The outer periphery of the wire bundle 13 is bound with one or more binding threads to achieve shaping. Alternatively, in another embodiment, 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 binding is achieved by a cross-linking 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 or threading, to achieve shaping. 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] In such Figure 17 and Figure 18 As shown, 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.

[0122] like Figure 19 The illustrated embodiments and Figure 18 The difference between the embodiments shown is that: Figure 17 and Figure 19 As shown, multiple wires 13 are twisted together to give the wires 13 an overall twisted shape. Under this overall twist, on the one hand, the wires 13 are not easy to fall off during processing, and on the other hand, the wire gaps 1A and wire channels 131 are no longer straight, but spiral-shaped, which extends the length of the airflow path, enhances the effect of heat convection heat transfer, and helps to reduce the temperature of the aerosol.

[0123] 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 overall twisting of multiple wires 13 (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 overall twisting of multiple wires 13 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.

[0124] like Figure 20 The illustrated embodiments and Figure 18 The difference between the embodiments shown is that: Figure 17 and Figure 20 As shown, 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 multiple strands 13 are intertwined, which makes it less likely for the strands 13 to fall off during processing. Furthermore, the gaps 1A and the strand channels 131 are no longer straight, but spiral-shaped, extending the length of the airflow path. This enhances the effect of heat convection and helps to reduce the aerosol temperature.

[0125] Figure 21 The illustrated embodiments and Figure 17 and Figure 18 The difference between the embodiments shown is that: Figure 21 As shown, the smoke generator 100 contains 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.

[0126] Figure 22 The illustrated embodiments and Figures 17 to 20 The difference in the illustrated embodiment is that at least a portion of the wires 13 in the smoke-generating body 100 are formed as shown in the figure. Figures 7 to 10 The composite line 1 is shown.

[0127] Figures 23 to 26 The illustrated embodiments and Figures 17 to 20 The difference between the embodiments shown is that: Figure 22 As shown in the figure, a sensor 15 is provided inside the smoke-generating body 100.

[0128] like Figure 23 As shown, 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. A wire gap 1A is also formed between the sensor 15 and the wire 13.

[0129] 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.

[0130] 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.

[0131] 1. External binding and shaping: The smoke-generating body 100 is bound with a single strand or multiple strands of thread around its periphery to achieve shaping. Alternatively, in another embodiment, single strands or multiple strands of thread are used to bind the smoke-generating body 100 within each rope, so that the thread used for binding is not exposed. Alternatively, 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 by sewing or threading, to achieve shaping.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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. To facilitate cutting the sensor 15 and achieve a more uniform distribution within the smoke-generating body 100, the sensor 15 can utilize more and finer metal wires, such as 50 strands of equal-sized ultrafine magnetic metal wires with a diameter of 0.05 mm 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 invention 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.

[0136] 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.

[0137] A single metal wire is a physical unit whose material composition is one of a single metal, a single alloy, or a composite metal.

[0138] 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), and Kovar alloy wire, etc.; composite metal wires contain two or more metal materials, including at least one magnetic material, and composite refers to being combined by means of rolling, electroplating, electroless plating, sputtering, welding, cladding, and coating.

[0139] 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 of this invention 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.

[0140] 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.

[0141] Based on this, other application scenarios and design parameters are derived as follows: 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.

[0142] 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.

[0143] Figure 24 The illustrated embodiments and Figure 23 The difference between the embodiments shown is that: Figure 24 As shown, at least a portion of the wire 13 in the smoke-generating body 100 forms a connection with the sensor 15 as shown in the diagram. Figure 15 The composite strand 1 shown; or, at least a portion of the wire 13 in the smoke generator 100 forms a shape with the sensor 15 as shown. Figures 11 to 13 The composite line 1 is shown.

[0144] Figure 25 The illustrated embodiments and Figure 23 The difference between the embodiments shown is that: Figure 25 As shown, at least a portion of the wire 13 in the smoke-generating body 100 forms a connection with the sensor 15 as shown in the diagram. Figure 14 The composite line 1 is shown.

[0145] like Figure 24 and 25In the illustrated embodiment, 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 stainless steel SUS 420 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.

[0146] 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. This provides advantages such as easy cutting during processing and uniform heating and carbonization during operation.

[0147] Some applications derived from this embodiment include: 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.

[0148] 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. Therefore, considering economic cost and manufacturability while achieving the necessary eddy current heating effect, this invention sets the diameter of a single metal wire in the sensor 15 of the tobacco cartridge between 0.01 and 1 mm.

[0149] 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.

[0150] In other application scenarios and design parameters, the following are derived: 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.

[0151] In some applications, the basic building blocks of the smoke generator 100 can be configured in a variety of easily manufactured combinations, for example, such as Figure 26 The embodiment shown, Figure 26 The illustrated embodiments and Figure 23 The difference in the illustrated embodiment is that the smoke generator 100 includes a wire 13, a sensor 15, and a composite strand 1. The composite strand 1 can be as follows: Figure 7-16 In any of the composite strands shown, the sensor 15 can be interwoven with the adjacent wire 13, and the wire 13 interwoven with the sensor can also be wire 13 in the composite strand 1, that is, the sensor 15 is interwoven with the composite strand 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 transmission and cooling. Wrapping the sensor 15 increases strength on the one hand, and on the other hand, prevents the sensor 15 from wrapping around the periphery of the smoke generator 100 or even contacting the second shaping layer 17, which could cause significant thermal impact on the second shaping layer 17 (usually containing paper) and the external smoke tube, leading to the generation of paper paste and glue smells. The smoke generator 100 can also have other constituent unit configurations. The premise of a reasonable configuration is to obtain an optimized smoke generator 100 with high porosity (the ratio of the open area in the cross-section to the overall cross-sectional area), good roundness, a symmetrical and uniform structure, and containing the necessary sensor 15.

[0152] The basic constituent unit configuration 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, the present invention uses a blending method to reduce breakage in textiles, etc. On the other hand, they ensure 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 the present invention, 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 discrete wire distribution 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 the roundness of its outer periphery better. This reduces the difficulty of subsequent tobacco cartridge splicing and improves the aesthetics of the tobacco 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 wire bundle fuller and the internal space accommodate more fiber filaments and metal wires, so that the structure is more stable during processing and ensures 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 small suction resistance. At the same time, when heated, the physical deformation trend of the internal units of the smoke-generating body 100 reaches a synergistic effect, 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.

[0153] Figure 27 The illustrated embodiments and Figure 23 The difference between the embodiments shown is that: Figure 26 As shown, at least a portion of the wire 13 in the smoke-generating body 100 is formed as follows: Figure 16 The composite line 1 is shown.

[0154] Figure 28 The illustrated embodiments and Figure 23 The difference between the embodiments shown is that: Figure 27 As shown, at least a portion of the wire 13 in the smoke-generating body 100 is formed as follows: Figures 7 to 10 The composite line 1 is shown.

[0155] 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 the diameter of each wire 13 is the same or substantially the same. 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 the diameter of each wire 13 is the same or substantially the same. 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.

[0156] In the above embodiments, the number of wires 13 is only an example, and the number of wires 13 disclosed herein is not limited to this.

[0157] In some embodiments, preferably, the number of wires 13 is 20-40.

[0158] 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.

[0159] More preferably, the number of wires 13 is 25-35.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] In the above embodiments, the sensor 15 can be a single metal wire or can be formed by multiple metal wires.

[0164] 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.

[0165] Alternatively, multiple metal wires can be twisted or interwoven to form a braided structure.

[0166] To verify the magnetic behavior of the sensor 15 during the process of heating from room temperature to a stable operating temperature, this invention tested the magnetization intensity M as a function of temperature (MT curve) and the magnetization intensity change rate dM / dT as a function of temperature T for the iron-nickel based alloy 4J29 material used as the sensor 15 in the temperature range of 20-573℃. Figure 29 As shown. Figure 29 This 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. As can be seen from the curve, before 400°C, the sensor 15 possesses a high and stable permeability, with a magnetization as high as 50 emu / g. After 400°C, its permeability rapidly decreases, reaching 0 at 450°C. Based on the peak and valley of dM / dT-T, its Curie temperature Tc can be determined to be 450°C. This magnetic change behavior has multiple values.

[0167] (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.

[0168] (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 an obvious inflection point at 400°C. The system finds the current inflection point Im corresponding to the temperature inflection point by the obvious change of 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.

[0169] (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 the magnetic change behavior and experimental data to achieve real-time temperature measurement, and there is no need to use physical sensors in the system.

[0170] (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 can achieve the purpose of anti-counterfeiting identification and prevent safety accidents caused by the use of incorrect cartridges or incorrect devices.

[0171] (5) Safety Protection: Two modes can be set, including active protection, passive protection, or a combination of both. Active protection, for example, when the temperature of sensor 15 abnormally exceeds 410°C, the magnetism of sensor 15 decreases significantly until it loses its magnetism. Correspondingly, the coupling strength decreases significantly until it loses coupling, that is, the power input is significantly reduced until it reaches the tube wall. Passive protection, for example, can set the threshold Is of Idc in the specific control configuration of the smoking device, corresponding to the threshold temperature Ts. When the temperature of sensor 15 exceeds the threshold temperature Ts, the system reduces or cuts off the power input.

[0172] 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.

[0173] like Figure 30As shown, 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.
