Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and more particularly to a multi-strand heating wire, an atomizer, and an atomizing device. Background Technology

[0002] Electronic cigarettes are a type of cigarette replacement product that has a similar appearance and flavor to traditional cigarettes. The formula can be adjusted to reduce or eliminate nicotine. Electronic cigarettes primarily work by heating e-liquid to produce vapor that mimics cigarette smoke.

[0003] Existing electronic cigarette heating elements generally fall into two categories: one is a mesh structure, which features a large heating area and rapid heating, but its resistance is limited, making it difficult to achieve high resistance within the existing spatial structure, and even harder to exceed 1 ohm. The second is a filamentous spiral mechanism, which has a small heating area, produces less vapor at the same power, has poor wicking performance, and is prone to coil clogging. In other words, existing heating elements cannot simultaneously possess the characteristics of controllable resistance and a large heating area, and their wicking performance also needs improvement, making it difficult to meet the required specifications. Summary of the Invention

[0004] In view of the above situation, it is necessary to provide a multi-strand heating wire, atomizer and atomizing device that simultaneously have controllable resistance and large heating area.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a multi-strand heating component, comprising: a heating element, including at least one first heating wire made of a thermally conductive material, extending in a spiral shape; a first pin, made of a poor thermal conductor, connected to one end of the heating element; a second pin, made of a poor thermal conductor, connected to the other end of the heating element; and a wire sleeve, made of a thermally conductive material, woven from multiple second heating wires and wrapped around the heating element, wherein the wire sleeve is woven from multiple second heating wires to form a mesh, and the mesh-shaped wire sleeve forms several oil storage grooves on the outer surface of the heating element.

[0006] Furthermore, each weaving intersection is formed by alternating a right-angled heating wire group consisting of at least two parallel, closely fitted, right-leaning second heating wires and a left-angled heating wire group consisting of at least two parallel, closely fitted, left-leaning second heating wires.

[0007] Furthermore, the first heating wire has multiple strands, with heat-resistant fibers sandwiched between the multiple strands of heating wire, and the first heating wire and the heat-resistant fibers are together sleeved inside the wire sheath.

[0008] Furthermore, the first pin and the second pin extend axially toward the same end and are parallel to the central axis of the heating element.

[0009] Furthermore, the number of the first heating wires is 16-32 strands, and the diameter of the hole formed by the spiral of the heating element is 2mm-4mm.

[0010] Furthermore, the sheath is made of a nickel-chromium alloy.

[0011] Furthermore, the first pin and the second pin are respectively spot-welded or riveted to the heating element.

[0012] The present invention also provides an atomizer, including the multi-strand heating element as claimed in the claim, the atomizer having an oil storage space for accommodating the multi-strand heating element, at least one of the multi-strand heating elements being disposed in the oil storage space, and an oil guide body being wrapped around the multi-strand heating element in the oil storage space, the spiral heating element forming an atomization channel for the flow of smoke.

[0013] Furthermore, the oil storage space is provided with two multi-strand heating components, the two multi-strand heating wire components are arranged side by side and the atomization channel is directly connected to the outlet of the atomizer.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the following detailed description of a multi-strand heating wire, atomizer, and atomizing device of this invention, in conjunction with the accompanying drawings and embodiments, is provided. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0026] Please see Figures 1-5 A multi-strand heating element 10 includes: a heating element 100, including at least one first heating wire 110 made of a thermally conductive material, extending in a spiral shape; a first pin 200, made of a poor thermal conductor, connected to one end of the heating element 100; a second pin 300, made of a poor thermal conductor, connected to the other end of the heating element 100; and a wire sheath 400, made of a thermally conductive material, woven from multiple second heating wires 410, wrapped around the heating element 100, the wire sheath 400 being woven from multiple second heating wires 410 to form a mesh, and the mesh-shaped wire sheath 400 forming several oil storage grooves on the outer surface of the heating element 100.

[0027] A mesh-like wire sleeve 400 is wrapped around the heating element 100. The increased wire sleeve 400 increases the heating area, and the heating element 100 facilitates resistance control. Structurally, it breaks through the limitations of traditional single heating wires. The wire sleeve 400 is woven from multiple second heating wires 410, which improves the strength of the wire sleeve 400 and prevents it from breaking during installation. The gaps between the second heating wires 410 also improve the oil guiding performance. The first pin 200 and the second pin 300 are made of poor thermal conductors, which can prevent heat from damaging other components, such as the conductive connectors between the first pin 200 and the second pin 300 and the battery. It also prevents the first pin 200 and the second pin 300 from affecting the oil guiding body 21, thereby avoiding damage to the oil guiding body 21 and ensuring uniform smoke distribution. The wire sleeve 400 forms several oil storage grooves on the surface of the heating element 100, which can increase the amount of smoke, facilitate the contact between the e-liquid and the first heating wire 110 and the second heating wire 410, improve the oil guiding performance, and facilitate the entry of air and the release of smoke.

[0028] Please see Figure 3 Each weaving intersection is formed by an alternating right-angled heating wire group consisting of at least two closely spaced, right-leaning second heating wires 410 arranged side-by-side and interleaved with a left-angled heating wire group consisting of at least two closely spaced, left-leaning second heating wires 410 arranged side-by-side and interleaved with a left-leaning heating wire group. Generally, the right-angled heating wire groups at two adjacent intersections extending along the same right-angled heating wire group are located on different sides of the left-angled heating wire group; or, specifically, adjacent second heating wires 410 at the same weaving intersection are located on opposite sides of the intersecting second heating wires 410. This tight weaving ensures uniform smoke distribution.

[0029] Generally, the diameter of the first heating wire 110 is larger than that of the second heating wire 410. This ensures that the heating element can withstand a larger power.

[0030] Please see Figure 5 The first heating wire 110 has multiple strands, with heat-resistant fibers sandwiched between them. The first heating wire 110 and the heat-resistant fibers 120 are together housed within the coil sleeve 400. The heat-resistant fibers 120, sandwiched between the first heating wires 110, can absorb e-liquid and impurities in the e-liquid, improving wicking performance and flavor. This allows for full contact between the first heating wire 110 and the heat-resistant fibers 120, resulting in better atomization. The heat-resistant fibers 120 can be made of natural fibers, glass fibers, or carbon fibers. Alternatively, when the number of strands of the first heating wire 110 is small, the heat-resistant fibers 120 can be placed on the outer surface of the heating element 100. Placing the heat-resistant fibers 120 on the outer surface of the heating element 100 allows for easy communication with the oil storage groove formed by the coil sleeve 400, improving wicking performance. Specifically, the heat-resistant fibers 120 are tubular with a receiving hole, capable of holding more e-liquid and better wicking impurities in the e-liquid; for more details, please refer to [link to relevant documentation]. Figure 4 and Figure 5 The receiving hole is equipped with an oil-absorbing column 130 with stronger oil absorption capacity. The oil-absorbing column 130 can be made of ceramic cotton or other materials to increase the amount of smoke. The oil guide body 21, heat-resistant fiber 120 and oil-absorbing column 130 outside the heating element 100 can all generate smoke. The heat-resistant fiber 120 isolates the oil-absorbing column 130 and the first heating wire 110, which can prevent the oil-absorbing column 130 from overheating and producing a burnt smell.

[0031] Please see Figure 1 and Figure 2 The first pin 200 and the second pin 300 extend axially towards the same end and are parallel to the central axis of the heating element 100. One of the first pin 200 and the second pin 300 is connected to the positive terminal of the battery and the other is connected to the negative terminal of the battery, thereby generating heat from the heating element 100 and the coil sleeve 400 to atomize the e-liquid. The parallel central axes of the heating element 100 facing the same end ensure that the heating element 100 is upright, allowing the smoke channel formed by the spiral heating element 100 to flow directly to the mouthpiece, resulting in smooth smoke flow, improved smoke effect, and enhanced flavor.

[0032] Generally, the number of first heating wires 110 is 4-64 strands, and the aperture of the spiral heating element 100 is 1mm-5mm. Preferably, the number of first heating wires 110 is 16-32 strands, and the aperture of the spiral heating element 100 is 2mm-4mm. Generally, the larger the aperture of the spiral heating element 100, the larger the smoke and the richer the flavor; the more strands, the higher the power supported, and the higher the power, the larger the smoke and the richer the flavor.

[0033] Preferably, the first pin 200 and the second pin 300 are respectively connected to the heating element 100 by spot welding or riveting.

[0034] Specifically, the sheath 400 is made of nickel-chromium alloy. Similarly, the heating element 100 can also be made of nickel-chromium alloy. Alternatively, the sheath 400 and heating element 100 can be made of other heat-conducting materials, such as copper, titanium alloy, or iron-chromium alloy; the materials can be the same or different, depending on the specific needs. The cross-sections of the heating element 100 and the heating wire can be selected as needed, such as circular, elliptical, square, or flat. In this invention, the cross-section of the heating element 100 is preferably circular or elliptical to avoid sharp edges cutting the sheath 400. Alternatively, the cross-section of the heating wire is preferably circular, elliptical, or a square with rounded corners to improve oil storage capacity.

[0035] Please see Figure 2The present invention also provides an atomizer 20, including the multi-strand heating element 10 as claimed in the claim. The atomizer 20 is provided with an oil storage space for accommodating the multi-strand heating element 10. At least one multi-strand heating element 10 is provided in the oil storage space. An oil guide body 21 is wrapped around the multi-strand heating element 10 in the oil storage space. An atomization channel for the flow of smoke is formed in the spiral heating element 100.

[0036] Generally, the outer sheath 400 is wrapped with an oil-conducting body 21. The oil-conducting body 21 absorbs the e-liquid and generates a large amount of smoke. The oil-conducting body 21 is generally made of fibrous, sponge-like, or foam-like materials, or other heat-resistant materials with oil-absorbing capacity. These include fibrous materials made from spun or extruded fibers, such as cotton, cellulose acetate, polyester or bonded polyolefin, polyethylene, polyester or polypropylene fibers, nylon fibers, glass fibers, ceramic wool, etc., high-temperature resistant oil-conducting cotton, and SEBS (a linear triblock copolymer with polystyrene as the end segment and styrene-butene copolymer obtained by hydrogenation of polybutadiene as the middle elastic block).

[0037] Please see Figure 2 The atomizing channel leads directly to the outlet of atomizer 20. This ensures smooth vapor flow and a better flavor.

[0038] The present invention also provides an atomizing device, including the atomizer 20 described above.

[0039] In summary, the multi-strand heating wire, atomizer, and atomizing device provided by the present invention cover the heating element with a mesh-like wire sleeve, which increases the heating area, facilitates resistance control, and improves wicking performance, resulting in larger, richer vapor and a more delicate flavor.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
