Technical Field
[0001] This application relates to the field of atomizing device technology, specifically to a heating element and an atomizing device. Background Technology
[0002] An atomizing device is a device that generates aerosols from an aerosol matrix by heating the matrix. The atomizing device heats the aerosol matrix using a heating element. Generally, the heating element includes a substrate and thick-film heating circuitry printed on the substrate. By connecting the two ends of the heating circuitry to the positive and negative terminals of a power source, the heating circuitry can generate heat, thereby heating the aerosol matrix.
[0003] To increase the area of the heating circuit, the heating circuit includes not only straight sections, but also bends connecting the straight sections (i.e., corners of the heating circuit). However, uneven heating at the corners of the heating circuit can easily lead to circuit breaks at the corners, affecting the heating and atomization of the aerosol matrix. Utility Model Content
[0004] This application provides a heating element and an atomizing device, which can solve the problem of uneven heating at the corners of the heating circuit, which affects the heating and atomization of the aerosol matrix.
[0005] To address the aforementioned technical problems, this application provides a heating element comprising a substrate, heating circuitry, and a collector wire. The heating circuitry is disposed on the substrate and includes at least two straight segments and at least one bent segment, with straight segments connecting to both ends of the bent segment. The bent segment has an inner edge and an outer edge disposed opposite to each other, the length of the inner edge being less than the length of the outer edge. At least a portion of the collector wire is disposed on the surface of the bent segment, and the collector wire extends from one end near the inner edge to one end near the outer edge.
[0006] In one embodiment, the end of the flow line near the outer edge is the outer end of the flow line, and the outer end of the flow line is located outside the outer edge to be disposed on the substrate.
[0007] In one embodiment, the number of flow lines provided on the same bend is at least two.
[0008] In one embodiment, at least two parallel flow lines are provided on the same bending segment.
[0009] In one embodiment, the flow lines arranged on the same bend are parallel to the length extension direction of the straight segments connected to the same bend.
[0010] In one embodiment, the heating circuit includes a first straight segment, a second straight segment, and a first bent segment connecting the first straight segment and the second straight segment. The length extension direction of the first straight segment is parallel to the length extension direction of the second straight segment. The edge of the first straight segment near the second straight segment is a first edge, and the edge of the second straight segment near the first straight segment is a second edge. A first collector line and a second collector line are provided on the first bent segment. The first collector line extends along the extension line of the first edge, and the second collector line extends along the extension line of the second edge.
[0011] In one embodiment, the flow line provided on the same bend segment and the length extension direction of the straight segment connected to the same bend segment have an acute angle or a right angle.
[0012] In one embodiment, a first group of collector lines and a second group of collector lines are provided on the same bend. Each of the first group of collector lines and the second group of collector lines includes two parallel collector lines, and there is an included angle between the collector lines of the first group of collector lines and the collector lines of the second group of collector lines.
[0013] In one embodiment, the first streamer group includes a third streamer and a fourth streamer, and the second streamer group includes a fifth streamer and a sixth streamer. One end of the third streamer and one end of the sixth streamer extend to a straight section, and the other end of the third streamer and the other end of the sixth streamer extend to a bent section. The fourth streamer and the fifth streamer intersect, and the intersection point is located in the bent section and is set near the inner edge of the bent section.
[0014] To address the aforementioned technical problems, this application provides an atomizing device, which includes a heating element as described in any of the above embodiments. The heating element is used to heat the atomized aerosol matrix to generate an aerosol from the aerosol matrix.
[0015] This application provides a heating element, which includes a substrate, a heating circuit, and a current collector. The heating circuit is disposed on the substrate and includes at least two straight segments and at least one bent segment, with straight segments connected to both ends of the bent segment. The bent segment has an inner edge and an outer edge disposed opposite to each other, with the length of the inner edge being less than the length of the outer edge. At least a portion of the current collector is disposed on the surface of the bent segment, and the current collector extends from one end near the inner edge to one end near the outer edge. When the current collector is not disposed, based on the principle of the shortest current path, the current is mainly concentrated in the area near the inner edge of the bent segment, causing excessive heating in the area near the inner edge of the bent segment, while the area near the outer edge of the bent segment has almost no current or very little heating. This application provides current collectors on the surface of the bending section of the heating circuit. The current collectors can collect current and change the current transmission path at the bending section. Compared with the heating circuit, the current will preferentially pass through the current collectors. Since the current collectors extend from one end near the inner edge to one end near the outer edge, the current can be guided to the outer edge of the bending section, which improves the situation of concentrated heating on the inner side of the bending section and improves the reliability of the heating circuit.

[0028] This application provides an atomizing device, which includes a heating element for heating an atomized aerosol matrix to generate an aerosol. The heating element can be used to heat atomized solid aerosol matrices or liquid aerosol matrices; that is, the heating element of this application can be applied to atomizing devices with liquid aerosol matrices or to atomizing devices with solid aerosol matrices, similar to heating non-combustible devices.
[0029] like Figure 1 As shown, the heating element includes a substrate 10, a heating circuit 20, and a current collector 30. The heating circuit 20 is disposed on the substrate 10. The substrate 10 can be a tubular structure or a solid structure. If the substrate 10 is a tubular structure, the heating circuit 20 can be disposed on the side wall of the tubular structure, for example, on the outer or inner side wall of the tubular structure. The substrate 10 can be an insulating material or a non-insulating material. When the substrate 10 is a non-insulating material, an insulating coating needs to be provided on the surface of the substrate 10. In some embodiments, the heating element also includes at least two electrodes 40, which are disposed on the substrate 10, and both ends of the heating circuit 20 are connected to electrodes 40 along its length. The two electrodes 40 at both ends of the heating circuit 20 along its length can be electrically connected to the positive and negative terminals of a power supply, respectively, so that the heating circuit 20 can generate heat. Of course, at least two segments of heating circuit 20 can be disposed on the substrate 10 of this application, and the electrodes 40 separate the different heating circuits 20. For example, in Figure 1 In one embodiment, there are two heating circuits 20 and three electrodes 40, with one end of the two heating circuits 20 sharing a common electrode.
[0030] The heating circuit 20 includes at least two straight segments 21 and at least one bent segment 22. Both ends of the bent segment 22 are connected to the straight segments 21, and the ends of the bent segment 22 refer to the two ends along its length extension direction. In one embodiment, the straight segments 21 at both ends of the bent segment 22 may be parallel to each other and spaced apart. Along the extension direction of the two straight segments 21, at least partially overlap, thus bending the bent segment 22 approximately 180 degrees. In other embodiments, the straight segments 21 at both ends of the bent segment 22 may also be perpendicular to each other and spaced apart, thus bending the bent segment 22 approximately 90 degrees. Of course, in other embodiments, the straight segments 21 at both ends of the bent segment 22 may also form acute or obtuse angles, so that the bent segment 22 bends at acute or obtuse angles.
[0031] The bent segment 22 has an inner edge 221 and an outer edge 222 that are oppositely arranged. The length of the inner edge 221 is less than the length of the outer edge 222. For example, when the bent segment 22 is approximately arc-shaped, the inner edge 221 is the edge of the bent segment 22 near the center, and the outer edge 222 is the edge of the bent segment 22 away from the center. In other embodiments, the bent segment 22 can also be a broken line structure. Regardless of the shape of the bent segment 22, the inner edge 221 of the bent segment 22 connects the two closest edges of two adjacent straight lines 21, and the outer edge 222 of the bent segment 22 connects the two farthest edges of two adjacent straight lines 21, so that the length of the outer edge 222 of the bent segment 22 is always greater than the length of the inner edge 221.
[0032] At least a portion of the flow line 30 is disposed on the surface of the bent section 22. In one embodiment, at least a portion of the flow line 30 is disposed on the surface of the bent section 22 away from the substrate 10, and the flow line 30 extends from one end near the inner edge 221 to one end near the outer edge 222. Here, only the general extension trend of the flow line 30 is mentioned, and the end of the flow line 30 may extend beyond the inner edge 221 or beyond the outer edge 222 and be disposed on the substrate 10, or the end of the flow line 30 may also extend to the straight segment 21 connected by the flow line 30, or the end of the flow line 30 may also be located inside the bent portion, or the end of the flow line 30 may be flush with the inner edge 221 or the outer edge 222.
[0033] The current collector 30 is a current collector with extremely low resistance, high conductivity, and high temperature resistance. For example, it can be made of silver wire. Preferably, the current collector 30 is made of the same material as the electrode, so that the current collector 30 and the electrode can be printed and sintered in the same process, reducing the manufacturing process of the heating element. Since the area of the heating circuit 20 covered by the current collector 30 does not generate heat, the current collector 30 should not be set to an excessively large area. Therefore, the current collector 30 can be set to have a narrow width and a thin thickness, both of which are much smaller than the length of the current collector 30, and can be roughly regarded as a line (ignoring the width and thickness of the current collector 30). The current collector 30 can be a straight line or a curve.
[0034] Without the collector 30, due to the principle of the shortest path for current, the current is mainly concentrated in the area near the inner edge 221 of the bend 22, causing excessive heating in this area, while the area near the outer edge 222 of the bend 22 has almost no current or very little heating. The principle of the shortest path for current is not a strict physical law, but a common expression used to describe how current tends to choose the path of least resistance when flowing in a circuit. This phenomenon can be derived from Ohm's law and Kirchhoff's laws, and its core is the manifestation of the principle of energy minimization in electricity. The shortest path does not necessarily refer to the shortest physical distance, but rather to the "easiest path" in an electrical sense, i.e., the path with the lowest resistance. For example, in a parallel circuit, if one path has a resistance of 1Ω and the other 10Ω, assuming the voltage is the same, the current will mainly flow through the 1Ω path. This application provides a current collector 30 on the surface of the bend 22 of the heating line 20. The current collector 30 can collect current to change the current transmission path at the bend 22. Compared with the heating line 20, the current will preferentially pass through the current collector 30. Since the current collector 30 extends from one end near the inner edge 221 to one end near the outer edge 222, it reduces the potential difference between the inner edge 221 and the outer edge 222. Therefore, the current can be guided to the outer edge 222 of the bend 22, which improves the situation of concentrated heating on the inner side of the bend 22 and improves the reliability of the heating line 20.
[0035] The fabrication process of the heating element in this application is as follows: 1. Obtaining a substrate 10; 2. Applying an insulating coating to the surface of the substrate 10 and sintering it; 3. Printing and sintering the heating circuit 20; 4. Printing and sintering the current collector 30 and the electrode 40; 5. Welding and sintering the leads; 6. Printing and sintering the anti-oxidation protective layer. The order of steps 3 and 4 can be interchanged. When the substrate 10 is an insulating material, step 2 can be omitted.
[0036] like Figure 2As shown, in one embodiment, the end of the flow collector 30 near the outer edge 222 is the outer end of the flow collector 30, which is located outside the outer edge 222 and disposed on the substrate 10. That is, the outer end of the flow collector 30 extends from the bent section 22 through the outer edge 222 to the substrate 10. In some embodiments, the end of the flow collector 30 near the inner edge 221 is the inner end of the flow collector 30, which is located inside the inner edge 221 and disposed on the substrate 10. That is, the inner end of the flow collector 30 extends from the bent section 22 through the inner edge 221 to the substrate 10. In some embodiments, the inner end of the flow collector 30 may also extend from the bent section 22 to the connected straight section 21. The length of the flow collector 30 extending beyond the bent section 22 is not limited. In a preferred embodiment, at least the outer end of the current collector 30 extends from the bend 22 through the outer edge 222 to the substrate 10, thereby directing current to the outer edge 222 and maximizing the current to the edge of the bend 22. If the outer end of the current collector 30 does not extend beyond the outer edge 222, the heating circuit outside the outer end of the current collector 30 may not heat up or generate very little heat, resulting in poor improvement of the concentrated heating effect.
[0037] In one embodiment, such as Figure 2 As shown, preferably, the number of current collectors 30 provided on the same bend segment 22 is at least two, for example, two or three. In one embodiment, at least two parallel current collectors 30 are provided on the same bend segment 22. By arranging at least two current collectors 30 parallel to each other on the same bend segment 22, the heating circuit 20 area between each current collector 30 provided on the same bend segment 22 can be heated evenly, because the potential difference between the two parallel current collectors 30 is equal everywhere, and it is not easy for current to preferentially pass through the shortest path.
[0038] In one embodiment, such as Figure 2 As shown, the flow lines 30 provided on the same bend segment 22 are parallel to the length extension direction of the straight segments 21 connected to the same bend segment 22. When the two straight segments 21 connected by the same bend segment 22 are not parallel, the flow lines 30 provided on the same bend segment 22 may be parallel to the length extension direction of only one of the straight segments 21 connected by the bend segment 22, or some flow lines 30 provided on the same bend segment 22 may be parallel to one of the straight segments 21 connected by the bend segment 22, and other flow lines 30 may be parallel to the other straight segment 21 connected by the bend segment 22.
[0039] like Figure 2As shown, when the bending segment 22 bends approximately 180 degrees, that is, when the two straight segments 21 connected by the bending segment 22 are parallel, specifically, in one embodiment, the heating circuit 20 includes a first straight segment 211, a second straight segment 212, and a first bending segment 223 connecting the first straight segment 211 and the second straight segment 212. The length extension direction of the first straight segment 211 is parallel to the length extension direction of the second straight segment 212. The edge of the first straight segment 211 near the second straight segment 212 is the first edge 2111, and the edge of the second straight segment 212 near the first straight segment 211 is the second edge 2121. Parallel first and second collector lines 31 and 32 are provided on the first bending segment 223. The first collector line 31 is positioned close to the extension line of the first edge 2111. The first collector line 31 can be located on the side of the extension line of the first edge 2111 that is either far from or close to the extension line of the second edge 2121, and is as close as possible to the extension line of the first edge 2111. Alternatively, the first collector line 31 extends along the extension line of the first edge 2111. The second collector line 32 is positioned close to the extension line of the second edge 2121. The second collector line 32 can be located on the side of the extension line of the second edge 2121 that is either far from or close to the extension line of the first edge 2111, and is as close as possible to the extension line of the second edge 2121. Alternatively, the second collector line 32 extends along the extension line of the second edge 2121. When the first collector line 31 extends along the extension line of the first edge 2111, and the second collector line 32 extends along the extension line of the second edge 2121, it can be referred to... Figure 3 The first streamline 31 and the second streamline 32 are unlikely to intersect, and the distance between them is as small as possible.
[0040] If the distance between the first collector line 31 and the second collector line 32 is large, for example Figure 2 In this embodiment, the heating line 20 further includes a third straight segment 213 and a second bent segment 224 connecting the second straight segment 212 and the third straight segment 213. Similarly, the third straight segment 213 is parallel to the second straight segment 212, and the second bent segment 224 turns approximately 180 degrees. A seventh collector line 37 and an eighth collector line 38 are arranged parallel to each other on the second bent segment 224. The spacing and arrangement of the seventh collector line 37 and the eighth collector line 38 are the same as those of the first collector line 31 and the second collector line 32. It can be seen that the distance between the second collector line 32 and the seventh collector line 37 is closer, making it easier to generate the shortest path between the second collector line 32 and the seventh collector line 37. Figure 3 As shown, by reducing the spacing between the first collector line 31 and the second collector line 32, as well as the spacing between the seventh collector line 37 and the eighth collector line 38, the distance between the second collector line 32 and the seventh collector line 37 is greater, and it is less likely that the shortest path will be generated between the second collector line 32 and the seventh collector line 37. This can improve the situation where the current only takes the shortest path and generates concentrated heat.
[0041] In one embodiment, such as Figure 4 As shown, the flow-collecting line 30 provided on the same bend 22 has an acute angle with the length extension direction of the straight segment 21 connected to the same bend 22, that is, the bend 22 is inclined relative to the straight segment 21. Or, as Figure 5 As shown, the flow lines 30 arranged on the same bend segment 22 are perpendicular to the length extension direction of the straight segment 21 connected to the same bend segment 22. Or, as Figure 6 As shown, some flow lines 30 arranged on the same bend 22 can be parallel to the length extension direction of the straight segment 21 connected to the same bend 22, while other flow lines 30 are perpendicular to the length extension direction of the straight segment 21 connected to the same bend 22. Or, as Figure 7 As shown, some flow lines 30 arranged on the same bend segment 22 can be parallel to the length extension direction of the straight segment 21 connected to the same bend segment 22; other flow lines 30 can be perpendicular to the length extension direction of the straight segment 21 connected to the same bend segment 22; and still others can have an acute angle with the length extension direction of the straight segment 21 connected to the same bend segment 22. In one embodiment, such as Figure 7 As shown, along the extension direction of the bend, the angle between the length extension direction of each flow line 30 set on the same bend 22 and the straight segment 21 connected to the same bend 22 gradually increases.
[0042] In one embodiment, such as Figure 4 As shown, a first group of collector lines 391 and a second group of collector lines 392 are provided on the same bend segment 22. Each of the first group of collector lines 391 and the second group of collector lines 392 includes two parallel collector lines 30, and there is an included angle between the collector lines of the first group of collector lines 391 and the collector lines of the second group of collector lines 392. Preferably, the included angle is a right angle.
[0043] In one embodiment, the first streamer group 391 includes a third streamer 33 and a fourth streamer 34, and the second streamer group 392 includes a fifth streamer 35 and a sixth streamer 36. One end of the third streamer 33 and one end of the sixth streamer 36 extend to a straight section 21, and the other end of the third streamer 33 and the other end of the sixth streamer 36 extend to a bent section 22. The fourth streamer 34 and the fifth streamer 35 intersect, and the intersection point is located in the bent section 22 and is set near the inner edge of the bent section. It can be seen that since the fourth collector line 34 intersects with the fifth collector line 35, the shortest path of current is formed at the intersection of the fourth collector line 34 and the fifth collector line 35. Therefore, the heat generation in the area between the fourth collector line 34 and the fifth collector line 35 is very small, and the phenomenon of current taking the shortest path at the corner still exists. However, in the area outside the fourth collector line 34 and the fifth collector line 35 (such as the area between the third collector line 33 and the fourth collector line 34), since each collector line group consists of two parallel collector lines 30, the phenomenon of concentrated heat generation near the corner will be improved, and the area of concentrated heat generation at the corner will be reduced.
[0044] Furthermore, from Figure 4 and Figure 3 A comparison of the embodiments shows that Figure 3 In the embodiments described above, the shortest path is easily generated between the second collector line 32 and the seventh collector line 37, that is, the shortest path is easily generated between the two collector lines 30 that are closest to each other on the two adjacent bend segments 22. Figure 4 As shown, when each collector line 30 is set at an angle, the two collector lines 30 closest to each other in two adjacent bends 22 can be set in parallel, and one end of each of the two collector lines 30 closest to each other in two adjacent bends 22 extends to the straight section 21. It can be seen that there is no shortest path between the two collector lines 30 closest to each other in two adjacent bends 22. This can prevent the problem of the two collector lines 30 closest to each other in two adjacent bends 22 from easily generating the shortest path.
[0045] The above description uses specific examples to illustrate this application, which are only for the purpose of helping to understand the invention and are not intended to limit the scope of this application. Those skilled in the art to which this application pertains can make several simple deductions, modifications, or substitutions based on the concept of this application.
