Description

Technical Field

[0001] This invention relates to the field of heating atomization technology, and more particularly to a tubular heating component. Background Technology

[0002] Heated atomization disperses liquids into smaller particles, allowing liquid molecules to be more dispersed in space. It has wide applications in industries such as medicine, agriculture, home appliances, and consumer electronics. Heated atomization has seen widespread use in recent years due to its ease of implementation and its ability to atomize most liquids. Innovation is particularly important for the heating element, the core component of heated atomization.

[0003] Currently, the most widely used heating element in the field of heated atomization is the columnar heating element, which is mainly divided into two types: one is a columnar heating element formed by a spiral heating wire, and the other is a tubular heating element formed by winding a mesh-like heating plate into a C-shape. Both types of heating elements have their two electrodes located at opposite ends of the heating element, which leads to the following problems: 1. The electrodes at both ends need to be led out to the same end through electrode leads. During design, the leads occupy space, causing the liquid-conducting material on the outside of the heating element to avoid the position of the leads when wrapping and matching, making assembly difficult; 2. The C-shaped tubular heating element is not a complete circle in the circumference, resulting in insufficient radial support and easy deformation, causing poor contact with the liquid-conducting material.

[0004] In addition, the heat output of current columnar heating elements is not easy to adjust, and dimensional changes are prone to occur during production and assembly, affecting product consistency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a tubular heating component that is easy to assemble and has high structural strength.

[0006] The technical solution adopted by the present invention to solve its technical problem is: to provide a tubular heating component, including an annular connecting part, at least two heating parts that are connected to one end face of the connecting part and arranged around the end face, and an electrode part connected to one end of the heating part away from the connecting part;

[0007] Each of the two opposite sides of the heating element is opposite to the corresponding side of the adjacent heating element and is left with a gap; at least two heating elements are connected in series through the connecting part.

[0008] Preferably, the heating element has a hollow structure.

[0009] Preferably, the hollow structure includes a plurality of through slots and / or a plurality of notches spaced apart along the length of the heating element; the hollow structure enables the heating element to form at least one heating circuit.

[0010] The heating circuit is in a meandering, zigzag, or wavy shape.

[0011] Preferably, the hollow structure is configured such that the heating element forms two heating circuits, which are connected and symmetrical.

[0012] Preferably, the hollow structure forms three heating lines in the heating part, wherein two heating lines are spaced apart and symmetrical, and the third heating line is connected between the first two heating lines.

[0013] Preferably, the hollow structure creates two connected and symmetrical heating zones in the heating element, each heating zone comprising two connected and symmetrical heating circuits.

[0014] Preferably, the width of the through groove and the notch is uniform.

[0015] Preferably, in the length direction of the heating element, the width of the through groove and / or notch located in the middle of the heating line is greater than the width of the through groove and / or notch located at both ends of the heating line.

[0016] Preferably, the heating circuit has multiple through holes spaced apart.

[0017] Preferably, the wall thickness of the heating element is 0.03mm-0.5mm.

[0018] Preferably, the electrode portion has at least one hollow portion.

[0019] Preferably, the tubular heating assembly includes two symmetrically arranged heating parts; each heating part is connected to an electrode part at one end away from the connecting part.

[0020] Preferably, the tubular heating assembly further includes electrode pins connected to the electrode portion.

[0021] The tubular heating element of the present invention is used in an atomizing device. It is tubular in shape and at least two relatively independent heating elements are connected together by a connecting part to form a series connection. This not only improves the structural strength of the heating element, but also enables it to have a larger resistance value compared to other heating elements of the same volume.

[0022] In addition, the electrode part is located at the same end of the heating component, which facilitates assembly in the atomizing device and connection to the battery. Attached Figure Description

[0034] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 , 2 As shown, the tubular heating assembly of the first embodiment of the present invention includes an annular connecting portion 10, at least two heating portions 20, at least two electrode portions 30, and electrode pins 40 connecting the electrode portions 30.

[0036] Along the axial direction of the entire heating assembly, the connecting part 10 and the electrode part 30 are located at their respective ends, and the heating part 20 is located in the middle and connected between the connecting part 10 and the electrode part 30.

[0037] The connecting portion 10 has two opposing annular end faces. The heating portion 20 is connected to one end face of the connecting portion 10 and is arranged around the end face. At least two heating portions 20 are spaced apart (not connected). The electrode portion 30 is connected to the end of the heating portion 20 away from the connecting portion 10. The electrode portions 30 are also spaced apart and are distributed with corresponding positive and negative electrodes. Each electrode portion 30 is connected to an electrode pin 40 for connecting to the positive and negative electrodes of a power source such as a battery.

[0038] Each heating element 20 has two opposing sides, each side of which is opposite to the corresponding side of the adjacent heating element 20 and is separated by a gap 50. At least two heating elements 20 are connected in series via a connecting part 10, thereby connecting to an external power source in series and achieving a higher resistance value compared to other heating elements of the same volume.

[0039] In the entire heating assembly, the connecting part 10 connects at least two relatively independent heating parts 20 into one unit, improving the strength of the tubular structure of the heating assembly. At least two electrode parts 30 are located at the same end of the heating assembly, facilitating assembly in the atomizing device and connection to the battery.

[0040] The heating element 20 has a hollow structure, which forms heating structures such as heating lines 21 on the heating element 20. The heating lines are long and have a small area, resulting in a higher resistance than the connecting part 10 and the electrode part 30, thus generating more heat when energized. In addition, the heat generation can be adjusted by adjusting the width and spacing of the heating lines 21.

[0041] Furthermore, the hollow structure may include a plurality of through slots 201 and / or a plurality of notches 202 arranged at intervals along the length of the heating part 20; the arrangement of the hollow structure causes the heating part 20 to form at least one heating line 21.

[0042] Specifically, the tubular heating assembly of this embodiment includes two symmetrically arranged heating portions 20; each heating portion 20 has an electrode portion 30 connected to its end away from the connecting portion 10. The hollow structure on each heating portion 20 includes multiple through slots 201 and multiple notches 202. The multiple through slots 201 are spaced apart along the length of the heating portion 20; two notches 202 are provided between every two adjacent through slots 201, and the two notches 202 are spaced apart and opposite to each other. The arrangement of the through slots 201 and notches 202 causes the heating portion 20 to include multiple sequentially connected heating rings along its length, and the spacer portion 203 between two opposite notches 202 forms a connecting structure for connecting the heating rings.

[0043] Dividing the heating element 20 along its centerline, it can be divided into two heating lines 21 with the centerline as the axis of symmetry; that is, the two heating lines 21 are connected and symmetrical; the two heating lines 21 are connected in parallel. Each heating line 21 can be configured as follows: Figure 2The meandering shape shown can also be in other forms such as a broken line or a wave.

[0044] Considering the overall strength of the heating component, the width L1 of the spacer 203 (between two opposing notches 202) located at the center line of the heating part 20 is preferably ≥ 2 times the width L2 of the notch 202.

[0045] In the tubular heating element, the wall thickness of the heating part is 0.03mm-0.5mm. Alternatively, the tubular part of the tubular heating element (including the connecting part 10, the heating part 20 and the electrode part 30) is an integral structure with an overall wall thickness of 0.03mm-0.5mm.

[0046] Tubular heating elements can be made from metal materials such as stainless steel alloys, nickel-chromium alloys, iron-chromium-aluminum alloys, titanium and titanium alloys, nickel-based alloys, and Hastelloy through cutting (specifically wire cutting, laser cutting, electrical discharge machining, etc.).

[0047] Alternatively, the tubular portion of the tubular heating element (including the connecting portion 10, the heating portion 20, and the electrode portion 30) can use a tube as the base, and form the connecting portion 10, the heating portion 20, and the electrode portion 30 on it through cutting or other processing methods. A hollow structure is then processed on the heating portion 20 to form the heating circuit 21. Alternatively, the tubular portion of the tubular heating element (including the connecting portion 10, the heating portion 20, and the electrode portion 30) can use a metal sheet as the base, and form a flat connecting portion 10, a flat heating portion 20, and a flat electrode portion 30 on it through cutting or other processing methods. A hollow structure is then processed on the heating portion 20 to form the heating circuit 21. Finally, the processed metal sheet is rolled into a tube shape, and the two ends of the connecting portion 10 are welded together.

[0048] Furthermore, the tubular heating assembly of the present invention can adjust the overall diameter of the heating assembly by increasing or decreasing the number of heating parts 20 and increasing or decreasing the width of the heating parts 20, depending on the required diameter.

[0049] like Figure 3 As shown, in the tubular heating assembly of the second embodiment of the present invention, the hollow structure on the heating part 20 includes a plurality of notches 202 that are spaced apart and interlaced along the length direction of the heating part 20. The arrangement of the plurality of notches 202 causes the heating part 20 to form a heating circuit 21.

[0050] A heating element 20 has one heating line 21. Compared to a heating element 20 with two or more heating lines 21, this reduces the width and allows for the formation of a heating component with a smaller diameter.

[0051] like Figure 4As shown, the tubular heating assembly of the third embodiment of the present invention differs from the first embodiment in that: the hollow structure on each heating part 20 forms two connected and symmetrical heating areas, and each heating area includes two connected and symmetrical heating lines 21. Therefore, each heating part 20 has four heating lines 21, and the four heating lines 21 are connected sequentially in the width direction of the heating part 20.

[0052] The heating element 20 in this embodiment is more suitable for tubular heating elements with larger diameter requirements than the tubular heating elements in the first and second embodiments described above.

[0053] Understandably, for tubular heating components with the same diameter requirement, the heating part 20 can also form one or more heating lines 21 according to requirements such as heat generation and atomization effect.

[0054] Combination Figure 2-4 In the tubular heating assembly of the first to third embodiments described above, the widths of the through grooves 201 and the notches 202 are uniformly set. That is, on the heating part 20, the widths of the multiple through grooves 201 are equal, the widths of the multiple notches 202 are also equal, and the widths of the through grooves 201 and the notches 202 can also be set equally.

[0055] like Figure 5 As shown, in the tubular heating assembly of the fourth embodiment of the present invention, unlike the first to third embodiments described above, the width of the through groove 201 and / or notch 202 located in the middle of the heating line 21 in the length direction of the heating part 20 is greater than the width of the through groove 201 and / or notch 202 located at both ends of the heating line 21.

[0056] Due to the principle of thermal radiation, the temperature in the middle of the heating element 20 is higher than that at both ends of the heating element 20. Therefore, by setting the width of the through groove 201 and / or notch 202 in the middle of the heating line 21 to be greater than the width of the through groove 201 and / or notch 202 at both ends of the heating line 21, the spacing in the middle of the heating line 21 is larger and the spacing at both ends is smaller, so that the overall heat generation of the heating element 20 is more uniform.

[0057] like Figure 6 As shown, the tubular heating assembly of the fifth embodiment of the present invention includes an annular connecting portion 10, at least two heating portions 20, at least two electrode portions 30, and electrode pins 40 connecting the electrode portions 30.

[0058] Along the axial direction of the entire heating assembly, the connecting portion 10 and the electrode portion 30 are located at their opposite ends, and the heating portion 20 is located in the middle and connected between the connecting portion 10 and the electrode portion 30. The connecting portion 10 has two opposing annular end faces, and the heating portion 20 is in contact with one end face of the connecting portion 10 and is arranged around that end face, with at least two heating portions 20 spaced apart (not in contact). The electrode portion 30 is connected to the end of the heating portion 20 away from the connecting portion 10, and the electrode portions 30 are also spaced apart, corresponding to positive and negative electrodes. Each electrode portion 30 is connected to an electrode pin 40 for connecting to the positive and negative terminals of a power source such as a battery. At least two heating portions 20 are connected in series through the connecting portion 10, thereby allowing for an external power supply in series, resulting in a higher resistance value compared to other heating elements of the same volume.

[0059] The heating element 20 has a hollow structure, which forms heating structures such as heating lines 21 on the heating element 20. The heating lines are long and have a small area, resulting in a higher resistance than the connecting part 10 and the electrode part 30, thus generating more heat when energized. In addition, the heat generation can be adjusted by adjusting the width and spacing of the heating lines 21.

[0060] With the hollow structure, one or more heating lines 21 can be formed on each heating element 21, as can be seen in the first to third embodiments described above. The width of the through slots and / or notches on the heating element 21 can be uniform or non-uniform, as can be seen in the first to third embodiments described above, or the fourth embodiment, which will not be repeated here.

[0061] Unlike the first to fourth embodiments described above, in this embodiment, the heating circuit 21 is provided with a plurality of spaced-apart through holes 204. The through holes 204 increase the surface area of ​​the heating circuit 21, resulting in higher thermal efficiency and faster heat dissipation.

[0062] like Figure 7 As shown, the tubular heating assembly of the sixth embodiment of the present invention includes an annular connecting portion 10, at least two heating portions 20, at least two electrode portions 30, and electrode pins 40 connecting the electrode portions 30.

[0063] Along the axial direction of the entire heating assembly, the connecting portion 10 and the electrode portion 30 are located at their opposite ends, and the heating portion 20 is located in the middle and connected between the connecting portion 10 and the electrode portion 30. The connecting portion 10 has two opposing annular end faces, and the heating portion 20 is in contact with one end face of the connecting portion 10 and is arranged around that end face, with at least two heating portions 20 spaced apart (not in contact). The electrode portion 30 is connected to the end of the heating portion 20 away from the connecting portion 10, and the electrode portions 30 are also spaced apart, corresponding to positive and negative electrodes. Each electrode portion 30 is connected to an electrode pin 40 for connecting to the positive and negative terminals of a power source such as a battery. At least two heating portions 20 are connected in series through the connecting portion 10, thereby allowing for an external power supply in series, resulting in a higher resistance value compared to other heating elements of the same volume.

[0064] The heating element 20 has a hollow structure, which forms heating structures such as heating lines 21 on the heating element 20. The heating lines are long and have a small area, resulting in a higher resistance than the connecting part 10 and the electrode part 30, thus generating more heat when energized. In addition, the heat generation can be adjusted by adjusting the width and spacing of the heating lines 21.

[0065] The specific arrangement of the hollow structure on the heating element 20 and the heating circuit 21, etc., can be referred to the first to fourth embodiments described above, and will not be repeated here.

[0066] In this embodiment, the electrode portion 30 is provided with at least one hollow portion 301. The hollow portion 301 can be a through-hole structure with a polygonal, circular, elliptical, or other shapes. The hollow portion 301 is preferably provided on the end of the electrode portion 30 near the heating portion 20.

[0067] Since the heat from the heating element 20 will be conducted to the electrode element 30, resulting in a higher temperature at the installation location of the electrode element 30, a perforated part 301 is provided in the electrode element 30 to reduce its heat conduction area, which can play a good role in heat insulation, so that the temperature difference between the electrode element 30 and the heating element 20 is smaller.

[0068] like Figure 8 As shown, the tubular heating assembly of the seventh embodiment of the present invention includes an annular connecting portion 10, at least two heating portions 20 that are connected to one end face of the connecting portion 10 and arranged around the end face, and an electrode portion 30 connected to one end of the heating portion 20 away from the connecting portion 10.

[0069] Each side of the heating element 20 is opposite to the corresponding side of the adjacent heating element 20 and has a gap; at least two heating elements 20 are connected in series through the connecting part 10. Each heating element 20 is connected to an electrode part 30, so the electrode parts 30 are spaced apart and have corresponding positive and negative electrodes. Each electrode part 30 is connected to an electrode pin 40 for connecting to the positive and negative electrodes of a power source such as a battery.

[0070] The heating element 20 has a hollow structure, which forms heating structures such as heating lines 21 on the heating element 20. The heating lines are long and have a small area, resulting in a higher resistance than the connecting part 10 and the electrode part 30, thus generating more heat when energized. In addition, the heat generation can be adjusted by adjusting the width and spacing of the heating lines 21.

[0071] In this embodiment, the hollow structure includes multiple through slots 201 and multiple notches 202 arranged at intervals along the length of the heating part 20, so that the heating part 20 forms two connected and symmetrical heating lines 21.

[0072] Furthermore, in this embodiment, by setting the rhomboid through-slot 201 and the triangular notch 202, each heating line 21 formed is in the shape of a broken line or a wave, and the entire heating part 20 is in the shape of a grid.

[0073] like Figure 9 As shown, the tubular heating assembly of the eighth embodiment of the present invention differs from that of the seventh embodiment in that: the hollow structure includes a plurality of through slots 201 and a plurality of notches 202 arranged at intervals along the length direction of the heating part 20, so that the heating part 20 forms three heating lines 21, wherein two heating lines 21 are spaced apart and symmetrical, and the third heating line 21 is connected between the first two heating lines 21. The diamond-shaped through slots 201 and triangular notches 202 make each heating line 21 form a zigzag or wavy shape, and the entire heating part 20 forms a grid.

[0074] In the seventh and eighth embodiments described above, the spacing of the heating circuit 21, the arrangement of through holes, and the arrangement of the hollowed-out portion on the electrode part 30 can all be set as needed. For details, please refer to the relevant settings in the first to sixth embodiments.

[0075] In the tubular heating assembly of the first to eighth embodiments described above, the electrode pins 40 are strip-shaped, forming electrode leads.

[0076] like Figure 10 As shown, the tubular heating assembly of the ninth embodiment of the present invention includes an annular connecting portion 10, at least two heating portions 20, at least two electrode portions 30, and electrode pins 40 connecting the electrode portions 30.

[0077] Along the axial direction of the entire heating assembly, the connecting portion 10 and the electrode portion 30 are located at their opposite ends, and the heating portion 20 is located in the middle and connected between the connecting portion 10 and the electrode portion 30. The connecting portion 10 has two opposing annular end faces, and the heating portion 20 is in contact with one end face of the connecting portion 10 and is arranged around that end face, with at least two heating portions 20 spaced apart (not in contact). The electrode portion 30 is connected to the end of the heating portion 20 away from the connecting portion 10, and the electrode portions 30 are also spaced apart, corresponding to positive and negative electrodes. Each electrode portion 30 is connected to an electrode pin 40 for connecting to the positive and negative terminals of a power source such as a battery. At least two heating portions 20 are connected in series through the connecting portion 10, thereby allowing for an external power supply in series, resulting in a higher resistance value compared to other heating elements of the same volume.

[0078] The heating element 20 has a hollow structure, which forms heating structures such as heating lines 21 on the heating element 20. The heating lines are long and have a small area, resulting in a higher resistance than the connecting part 10 and the electrode part 30, thus generating more heat when energized. In addition, the heat generation can be adjusted by adjusting the width and spacing of the heating lines 21.

[0079] As needed, in this embodiment, the electrode portion 30 may be provided with at least one hollow portion 301. By providing the hollow portion 301 on the electrode portion 30, its heat-conducting area is reduced, which can play a good heat insulation role, making the temperature difference between the electrode portion 30 and the heating portion 20 smaller. The hollow portion 301 can be a through-hole structure with a polygonal, circular, elliptical, or other shapes. The hollow portion 301 is preferably provided on the end of the electrode portion 30 near the heating portion 20.

[0080] Unlike the first to eighth embodiments described above, in this embodiment, the electrode pin 40 is an electrode sheet extending outward from the end of the electrode portion 30 away from the heating portion 20. The electrode sheet can further be bent relative to the electrode portion 30 to increase the connection area with a power source such as a battery, and can also form a support foot for fixed support.

[0081] The tubular heating element of this invention can have a circular, polygonal, or other cross-sectional shape. When applied in an atomizing device, the liquid guiding component of the atomizing device can be inserted inside the tubular heating element, with its outer surface in contact with the inner surface of the tubular heating element, achieving liquid guiding and heating atomization. Alternatively, the liquid guiding component can be sleeved around the outer periphery of the tubular heating element, with its inner surface in contact with the inner surface of the tubular heating element, achieving liquid guiding and heating atomization.

[0082] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
