Specific Implementation

[0036] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections.

[0037] This application provides a heating element used in an atomizing device to heat an aerosol-generating matrix within the atomizing device to form an aerosol when the atomizing device is in use.

[0038] Referring to Figures 1 to 6, the heating element includes a first pin 10, a second pin 20, and at least one heating unit 30; wherein the first pin 10 and the second pin 20 extend along a first direction X and are spaced apart in a second direction Y; the heating unit 30 may have one or at least two, and when there are at least two heating units 30, the at least two heating units 30 are spaced apart along the first direction X and the shapes of adjacent two heating units 30 are symmetrical; the heating unit 30 is in the shape of a periodic curve, one end of the heating unit 30 is connected to the first pin 10, and the other end is connected to the second pin 20.

[0039] Referring further to Figures 1 and 4, the first pin 10 and the second pin 20 extend along a first direction X, and are spaced apart in a second direction Y. The first pin 10 and the second pin 20 are arranged side-by-side and parallel, located at opposite ends of the heating element in the second direction Y. The first pin 10 and the second pin 20 are used to connect to a power supply assembly, thereby providing the heating element with the electrical energy required for operation.

[0040] In this embodiment, the heating unit 30 is the main part of the heating element used for heating. One end of the heating unit 30 is connected to the first pin 10, and the other end is connected to the second pin 20. The heating unit 30 is connected to the power supply component through the first pin 10 and the second pin 20 to obtain the required electrical energy during operation. The number of heating units 30 in the heating element is set according to the usage requirements. For example, there may be one heating unit 30. Alternatively, referring to Figures 1 and 4, two heating units 30 are shown, which are spaced apart along the first direction X, and the two heating units 30 are symmetrical in shape.

[0041] In the heating element of this embodiment, the heating unit 30 has a periodic curve shape. The structure of the heating unit 30 is relatively uniform, and its mechanical strength is relatively high. The heating unit will not deform during repeated heating and cooling processes. The heating unit 30 has good heating uniformity and is not prone to breakage due to stress concentration, nor to local overheating caused by affecting the heat distribution of the heating wire, which would affect the service life of the heating element. Moreover, the periodic curve shape of the heating unit 30 results in a longer length, which increases the heating area of ​​the heating unit 30 and gives the heating element greater power. Therefore, the heating element of this embodiment has the advantages of good heating uniformity, long service life, and high power.

[0042] Furthermore, the heating element exhibits good heating uniformity, and its resistance changes uniformly with temperature, enabling precise temperature control of the heating element.

[0043] In one or more embodiments, as shown in FIG3 and FIG6, the heating unit 30 includes a plurality of sub-units 31 and a plurality of first connecting portions 32; the plurality of sub-units 31 are arranged at intervals in the second direction Y, and the first connecting portions 32 are connected between two adjacent sub-units 31; the sub-units 31 have curved portions, and the curved portions have smooth transitions.

[0044] In the above structure of this application embodiment, the sub-units 31 have the same shape, and multiple sub-units 31 are arranged at intervals in the second direction Y. The shape of the heating element is relatively regular, which is the shape of a regular periodic curve. The heating unit 30 has the advantage of good heating uniformity. Moreover, the smooth transition of the curved part can make the current flow smoother, the current distribution relatively uniform, the resistance change smaller, and the power density closer to the average level, thereby making the heating unit 30 heat up relatively uniformly.

[0045] It should be noted that in the example shown in Figure 3, the sub-unit 31 is in the shape of a "U"; in the example shown in Figure 6, the sub-unit 31 is in the shape of an "Ω"; in other embodiments, the sub-unit 31 may also be other shapes with curved portions, such as a half-wave shape, and is not limited to the embodiments and figures of this application.

[0046] In one or more embodiments, referring to Figures 3 and 6, subunit 31 includes a first extension segment 311, a second extension segment 312, and a third extension segment 313, which are connected sequentially. The connection between the first extension segment 311 and the second extension segment 312, and the connection between the second extension segment 312 and the third extension segment 313, form a bend. In each subunit 31, the end of the first extension segment 311 facing away from the second extension segment 312 is connected to the end of a first connecting portion 32, and the end of the third extension segment 313 facing away from the second extension segment 312 is connected to the end of another first connecting portion 32. The first connecting portion 32 is arranged along the second direction Y. The bend, the connection between the first extension segment 311 and the first connecting portion 32, and the connection between the third extension segment 313 and the first connecting portion 32 are all smoothly transitioned.

[0047] Referring to Figures 3 and 6, in each subunit 31, a first extension segment 311, a second extension segment 312, and a third extension segment 313 are arranged sequentially in the second direction Y. The first extension segment 311, the second extension segment 312, and the third extension segment 313 are connected sequentially to form a structure with two bends.

The connection between the second end of the first extension segment 311 and the first end of the second extension segment 312 forms the first bend, and the connection between the second end of the second extension segment 312 and the first end of the third extension segment 313 forms the second bend.

[0048] In this embodiment, the curved portion, the connection between the first extension 311 and the first connecting portion 32, and the connection between the third extension 313 and the first connecting portion 32 are all smoothly transitioned, which can make the current flow smoother, the current distribution relatively uniform, the resistance change smaller, and the power density closer to the average level, thereby making the heating unit 30 heat up relatively uniformly.

[0049] Furthermore, the smooth transition portion can have a structure such as an arc shape.

[0050] In one or more embodiments, the first extension segment 311 and the third extension segment 313 are symmetrically arranged, and the second extension segment 312 extends along the second direction, so that each sub-unit 31 itself is also a symmetrically arranged structure.

[0051] In one or more embodiments, referring to Figures 1 and 3, the first extension segment 311 and the third extension segment 313 both extend along a first direction X, and the second extension segment 312 extends along a second direction Y. The first extension segment 311, the second extension segment 312, and the third extension segment 313 are connected to form a rectangular structure, where the first extension segment 311, the second extension segment 312, and the third extension segment 313 are the three sides of the rectangular structure. The above-described structure of the embodiments of this application provides the advantage that the subunit 31 has a regular structure and is easy to manufacture.

[0052] In one or more embodiments, referring to Figures 4 and 6, the second extension segment 312 extends along the second direction Y, and the first extension segment 311, the second extension segment 312, and the third extension segment 313 are connected to form a trapezoidal structure. The first extension segment 311 and the third extension segment 313 are the waists of the trapezoidal structure, and the second extension segment 312 is the lower base of the trapezoidal structure. The above-described structure of the embodiments of this application has the advantages of regular structure and ease of processing for the subunit 31.

[0053] In one or more embodiments, referring to Figures 3 and 6, the heating unit 30 further includes a second connecting portion 33 and a third connecting portion 34, which are symmetrically arranged on both sides of a plurality of sub-units 31. The first end of the second connecting portion 33 is bent toward the first pin 10 and connected to the first pin 10, and the second end of the second connecting portion 33 is connected to the first extension segment 311 or the third extension segment 313 closest to the first pin 10 through the first connecting portion 32. The second connecting portion 33 is symmetrically arranged with the first extension segment 311 or the third extension segment 313 closest to the first pin 10. The first end of the third connecting portion 34 is bent toward the second pin 20 and connected to the second pin 20, and the second end of the third connecting portion 34 is connected to the first extension segment 311 or the third extension segment 313 closest to the second pin 20 through the first connecting portion 32. The second connecting portion 33 is symmetrically arranged with the first extension segment 311 or the third extension segment 313 closest to the second pin 20.

[0054] Referring further to FIG3, the second connecting part 33 and the third connecting part 34 are disposed on both sides of the plurality of sub-units 31. The second connecting part 33 is located between the first pin 10 and the plurality of sub-units 31, and the third connecting part 34 is located between the second pin 20 and the plurality of sub-units 31. The second connecting part 33 and the third connecting part 34 are symmetrically arranged.

[0055] The first end of the second connecting part 33 is a bent structure. The first end of the second connecting part 33 is bent toward the first pin 10 and connected to the first pin 10. The second end of the second connecting part 33 is connected to one end of the first connecting part 32. The other end of the first connecting part 32 is connected to the end of the leftmost first extension segment 311 that is away from the second extension segment 312. That is, the second end of the second connecting part 33 is connected to the leftmost first extension segment 311 through the first connecting part 32. The second connecting part 33 and the leftmost first extension segment 311 are symmetrically arranged.

[0056] The first end of the third connecting part 34 is a bent structure, and the first end of the third connecting part 34 is bent toward the second pin 20 and connected to the second pin 20; the second end of the third connecting part 34 is connected to one end of the first connecting part 32, and the other end of the first connecting part 32 is connected to the end of the rightmost third extension segment 313 away from the second extension segment 312. That is, the second end of the third connecting part 34 is connected to the rightmost third extension segment 313 through the first connecting part 32, and the third connecting part 34 and the rightmost third extension segment 313 are symmetrically arranged.

[0057] In this embodiment, multiple sub-units 31 are connected between the first pin 10 and the second pin 20 via the second connecting portion 33 and the third connecting portion 34. The first end of the second connecting portion 33, the connection point between the second connecting portion 33 and the first connecting portion 32, the connection point between the first connecting portion 32 and the leftmost first extension segment 311, the first end of the third connecting portion 34, the connection point between the third connecting portion 34 and the first connecting portion 32, and the connection point between the first connecting portion 32 and the rightmost third extension segment 313 are all smoothly transitioned. This ensures smoother current flow, more uniform current distribution, smaller resistance variations, and a power density closer to the average level, thereby resulting in more uniform heating of the heating unit 30.

[0058] Wherein, along the second direction Y, the projection of the first end of the second connecting portion 33 onto the first extension segment 131 or the third extension segment 313 closest to the first pin 10 is located at the middle of the first extension segment 131 or the third extension segment 313 in the first direction X; along the second direction Y, the projection of the first end of the third connecting portion 34 onto the first extension segment 131 or the third extension segment 313 closest to the second pin 20 is located at the middle of the first extension segment 131 or the third extension segment 313 in the first direction X.

[0059] In one or more embodiments, two adjacent heating units 30 are grouped together, and the heating element has at least one group of heating units 30, wherein the second end of the second connection portion 42 of one heating unit 30 in each group is closer to another heating unit 30 than the first end.

[0060] In one or more embodiments, referring to Figures 1 and 4, the thickness of the heating element in a third direction Z, perpendicular to the first direction X and the second direction Y, ranges from 0.05 mm to 0.15 μm. In this case, the thickness of the heating element meets the power density requirements of the heating element.

[0061] It is understandable that the specific thickness of the heating element is set according to the usage requirements. For example, the thickness of the heating element is 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.10mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, 0.15mm, and multiple values ​​between the above.

[0062] In one or more embodiments, the width of the curve ranges from 0.08 mm to 0.5 mm. When the width of the curve in the embodiments of this application is within the above range, the heating unit 30 has the advantage of a larger area. Referring to FIG3, in this curve, the width of the first extension segment 311 is the distance from the left edge to the right edge of the first extension segment 311, and the width of the second extension segment 312 is the distance from the upper edge to the lower edge of the second extension segment 312.

[0063] Understandably, the specific width of the curve is set according to the usage requirements. For example, the curve width can be 0.08mm, 0.09mm, 0.10mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, or multiple values ​​between the above.

[0064] In one or more embodiments, referring to Figures 1 and 4, the heating element further includes a first conductive part 41 and a second conductive part 42. Both the first conductive part 41 and the second conductive part 42 are elongated sheet-like structures. The first conductive part 41 extends along the first direction X and is connected to the first pin 10, and the second conductive part 42 extends along the first direction X and is connected to the second pin 20. One end of the heating unit 30 is connected to the first pin 10 through the first conductive part 41, and the other end of the heating unit 30 is connected to the second pin 20 through the second conductive part 42.

[0065] In this embodiment, both the first conductive part 41 and the second conductive part 42 are elongated sheet-like structures. The first conductive part 41 has a larger connection area with the heating unit 30 compared to the first pin 10, making the connection between the first conductive part 41 and the heating unit 30 relatively simple, thus facilitating the connection of one end of the heating unit 30 to the first pin 10 via the first conductive part 41. Similarly, the second conductive part 42 has a larger connection area with the heating unit 30 compared to the second pin 20, making the connection between the second conductive part 42 and the heating unit 30 relatively simple, thus facilitating the connection of the other end of the heating unit 30 to the second pin 20 via the second conductive part 42.

[0066] In one or more embodiments, the heating element is selected from materials that meet the usage requirements, such as components made of iron-chromium-aluminum alloy, nickel-chromium-iron alloy, etc. Both iron-chromium-aluminum alloy and nickel-chromium-iron alloy have high electrical conductivity and high temperature resistance, giving the heating element the advantage of good heating uniformity. This avoids oxidation and corrosion of the heating element caused by localized overheating, thereby preventing performance degradation and shortened lifespan of the heating wire. Therefore, the heating element in this application embodiment also has the advantages of excellent heating performance and long lifespan.

[0067] In one or more embodiments, simulation software is used to calculate the resistance of the heating element, calculate the power density distribution of the heating element, design a reinforcement structure, and increase the heating area. The heating element is used in relevant cartridge replacement products, and the maximum power of a single heating element can be quite high, for example, up to 40W.

[0068] Referring to Figures 7 to 9, which illustrate simulation results, and specifically Figures 7 and 8, which show simulation diagrams of the power density of the heating element in two embodiments of this application, it is shown that the heating element has the advantages of high heat generation and good heating performance. Furthermore, the highest power densities at the corners of the heating element (including bends) are 5.71e10 and 6.18e10, respectively, indicating that overheating is less likely. In summary, the heating element of the embodiments of this application has the advantages of uniform overall heating, small temperature differences, and high energy utilization.

[0069] Referring further to Figure 9, which shows a simulation result diagram of a conventional heating element, this conventional heating element has two conductive paths at its center for heating. After heating, the heat diffuses upwards and downwards through these two conductive paths. The highest power density at the corner of the conventional heating element reaches 1.43e12, which easily leads to overheating and core clogging. Moreover, the heating of the conventional heating element is uneven, with only the two conductive paths heating. The temperature of these two conductive paths rises rapidly and reaches a high temperature. The parts of the conventional heating element other than the two conductive paths heat through heat transfer, resulting in a slower temperature rise and a lower temperature. All of these factors combined lead to low energy utilization of the conventional heating element.

[0070] By comparing the simulation diagrams of the heating elements of the two embodiments of this application shown in Figures 7 and 8 with the simulation diagram of the conventional heating element shown in Figure 9, it is easy to see that the heating elements of the two embodiments provided by this application have higher power density, higher energy utilization, better heating uniformity, and a larger heating area. In practical applications, this can solve the problem of burnt smell when using high power in the resistance range of 0.7Ω-0.9Ω.

[0071] This application provides an atomizing core, which includes a liquid storage component 50 and the aforementioned heating element. Referring to Figures 2 and 5, the liquid storage component 50 wraps around the outer periphery of at least one heating unit 30 in the heating element.

[0072] Referring to Figures 2 and 5, the heating element is rolled into a cylindrical structure during use, and the liquid storage component 50 is wrapped around the outer periphery of the cylindrical structure. The liquid storage component 50 wraps around the outer periphery of all heating units 30, maximizing the contact area with the heating units 30, which helps the aerosol generation matrix in the liquid storage component 50 to form an aerosol.

[0073] Of course, in practical applications, the heating element can also be in the uncurled state as shown in Figures 1 and 4. The heating element can be bent according to usage requirements; this application does not impose specific limitations on this.

[0074] The atomizing core of this application uses the above-mentioned heating element. Since the heating element has the advantages of good heating uniformity, long service life, high power and high energy utilization, the aerosol formed by the atomizing core is uniform, the service life of the atomizing core is longer, and the problem of overheating and burning of the core is not easy to occur.

[0075] This application also provides an atomizing device, which includes a power supply component and the aforementioned atomizing core. The power supply component provides power to the atomizing core, enabling the atomizing core to atomize an aerosol to generate a matrix and form an aerosol, thus realizing the function of the atomizing device.

[0076] In the embodiments of this application, the heating element, atomizing core, and atomizing device can be referenced to each other and have the same or similar beneficial effects as any of the aforementioned heating elements and atomizing cores. To avoid repetition, they will not be described again here.
