[0061] Various exemplary embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this application.

[0062] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0063] Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and apparatus should be considered part of the specification.

[0064] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0065] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0066] Figure 1 and Figure 2 The heating assembly of an atomizer in the prior art is shown.

[0067] like Figure 1 As shown, the heating circuit in the prior art is an S-shaped circuit 1 of equal width. During assembly, circuit 1 is connected in series between the positive electrode 2 and the negative electrode 3. From Figure 1 It is clearly visible that Line 1 includes an upper line, a middle line, and a lower line. The upper, middle, and lower lines are concentrated in the middle area of ​​the porous ceramic substrate. The empty area between the junction box 4 and Line 1 is relatively large, which makes the layout of Line 1 concentrated on the porous ceramic substrate. The heat generated on Line 1 is too concentrated, the heat distribution is uneven, and the atomization effect is poor.

[0068] like Figure 2 As shown, in the prior art, the distance between two adjacent heating sections in heating circuit 1 is small, and the heat generated by circuit 1 is concentrated in... Figure 2 The rectangular and elliptical boxes shown (in darker colors) indicate that line 1 generates excessively concentrated heat, resulting in uneven heat distribution and poor atomization.

[0069] Based on this, the inventors of this application, through long-term creative work, have come up with the following invention.

[0070] The heating assembly 100 of the atomizer according to an embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0071] like Figure 3 As shown, the heating assembly 100 of the atomizer according to an embodiment of this application includes: a porous ceramic substrate 10, a first terminal block 20, a second terminal block 30, and a strip heating element 40.

[0072] Specifically, the first terminal block 20 and the second terminal block 30 are disposed on the porous ceramic substrate 10 at intervals along the first direction of the porous ceramic substrate 10.

[0073] A strip-shaped heating element 40 is disposed on a porous ceramic substrate 10. One end of the strip-shaped heating element 40 is connected to a first terminal block 20, and the other end of the strip-shaped heating element 40 is connected to a second terminal block 30. The strip-shaped heating element 40 is arranged between the first terminal block 20 and the second terminal block 30.

[0074] The strip heating element 40 extends along the curve and includes a first heating section 41, a second heating section 42 and a third heating section 43. The first heating section 41 is located between the third heating section 43 and the first terminal block 20, and the second heating section 42 is located between the third heating section 43 and the second terminal block 30.

[0075] The third heating segment 43 and the first heating segment 41 extend approximately along the second direction of the porous ceramic substrate 10, with the first heating segment 41 curving towards the first terminal block 20. The second direction is perpendicular to the first direction. It should be noted that the phrase "extends along the second direction of the porous ceramic substrate 10" in this application has two meanings. First: The third heating segment 43 and the first heating segment 41 extend strictly along the second direction of the porous ceramic substrate 10. Second: The third heating segment 43 and the first heating segment 41 extend approximately along the second direction of the porous ceramic substrate 10. This application's embodiments tend to favor the second meaning. Here, "approximately" can be understood as follows: Since the strip-shaped heating element 40 extends along a curve, the corresponding third heating segment 43 and the first heating segment 41 typically do not extend along a straight line. Therefore, the extension trend of the third heating segment 43 and the first heating segment 41 basically coincides with the second direction, or deviates within a predetermined range.

[0076] The minimum distance between the first heating segment 41 and the third heating segment 43 in the first direction is a first distance H1;

[0077] The first distance H1 is greater than the maximum distance between the first heating section 41 and the first terminal block 20 in the first direction.

[0078] Specifically, the heating assembly 100 of the atomizer according to the embodiments of this application mainly consists of a porous ceramic substrate 10 that can play a supporting role, a first electrode 13 and a second electrode 14 disposed on the porous ceramic substrate 10; a first terminal block 20 and a second terminal block 30 that can play a role in electrically connecting with the first electrode 13 and the second electrode 14; and a strip heating element 40 that can generate heat after being powered on.

[0079] The porous ceramic substrate 10 has a first edge 11 and a second edge 12 extending along a first direction, and the first edge 11 and the second edge 12 are spaced apart in a second direction. For example, as Figure 3As shown, the first direction can be defined as the left-right direction, and the second direction as the up-down direction. Of course, the first direction is not limited to the left-right direction, and the second direction is not limited to the up-down direction; these are not limited here. The first edge 11 and the second edge 12 extend along the left-right direction and are spaced apart in the up-down direction. The area between the first edge 11 and the second edge 12 can serve as a mounting area, for example, for mounting the first terminal block 20, the second terminal block 30, and the strip heating element 40. It should be noted that the porous ceramic substrate 10 can be a porous ceramic substrate or other porous ceramic substrates; these are not limited here.

[0080] A first electrode 13 and a second electrode 14 are mounted on a porous ceramic substrate 10. The first electrode 13 and the second electrode 14 are respectively a positive electrode and a negative electrode, and the positive and negative electrodes are spaced apart along a first direction. Figure 3 As shown, the positive electrode is located on the left part of the porous ceramic substrate 10, and the negative electrode is located on the right part of the porous ceramic substrate 10.

[0081] A first terminal block 20 and a second terminal block 30 are also mounted on the porous ceramic substrate 10, and the first terminal block 20 and the second terminal block 30 are spaced apart along a first direction. Figure 3 As shown, the first terminal block 20 is disposed around the positive electrode and can be electrically connected to the positive electrode, and the second terminal block 30 is disposed around the negative electrode and can be electrically connected to the negative electrode.

[0082] like Figure 3 As shown, a strip-shaped heating element 40 is disposed on a porous ceramic substrate 10. The left end of the strip-shaped heating element 40 is electrically connected to the first terminal block 20 corresponding to the positive electrode, and the right end of the strip-shaped heating element 40 is electrically connected to the second terminal block 30 corresponding to the negative electrode. It should be noted that, alternatively, the left end of the strip-shaped heating element 40 can be electrically connected to the second terminal block 30 corresponding to the negative electrode, and the right end of the strip-shaped heating element 40 can be electrically connected to the first terminal block 20 corresponding to the positive electrode; this is not a limitation.

[0083] When the positive and negative electrodes are energized, the current can flow out from the positive electrode, pass through the first terminal block 20 surrounding the positive electrode, and flow to the left end of the strip heating element 40. Then the current flows from the left end of the strip heating element 40 to the right end of the strip heating element 40. Finally, the current flows to the negative electrode after passing through the second terminal block 30 surrounding the negative electrode, forming a complete circuit, thereby causing the strip heating element 40 to generate heat.

[0084] The strip heating element 40 includes a first heating section 41 and a third heating section 43. The first heating section 41 and the third heating section 43 are arranged opposite to each other. The third heating section 43 is located in the area where the heating sections of the strip heating element 40 are concentrated.

[0085] If the distance between adjacent heating sections is small in the concentrated distribution area of ​​the heating section, it is easy to generate heat concentration points in this area, which makes the heat generated by the strip heating element 40 unevenly distributed on the porous ceramic substrate 10, affecting the service life of the strip heating element 40 and the porous ceramic substrate 10.

[0086] In this embodiment, the first heating segment 41 bends towards the first terminal block 20. Therefore, the first heating segment 41 is an arc-shaped segment. The opening of the arc-shaped segment faces the third heating segment 43, thereby increasing the minimum distance between the first heating segment 41 and the third heating segment 43.

[0087] By increasing the minimum distance between the first heating section 41 and the third heating section 43, the heat distribution generated by the strip-shaped heating element is made more uniform, improving the heating uniformity of the e-liquid. To further improve the uniformity of heat distribution on the porous ceramic substrate 10 generated by the strip-shaped heating element 40, in this application, reference is made to... Figure 3 As shown, the minimum distance between the first heating segment 41 and the third heating segment 43 in the first direction is defined as the first distance H1; the first distance H1 is greater than the maximum distance between the first heating segment 41 and the first terminal block 20 in the first direction. That is, in this embodiment, the first heating segment 41 is bent towards the first terminal block 20, so that the minimum distance between the first heating segment 41 and the third heating segment 43 in the first direction is greater than the maximum distance between the first heating segment 41 and the first terminal block 20 in the first direction.

[0088] For example, in one specific embodiment, the first terminal block 20 itself does not generate heat. Therefore, this embodiment, by placing the first heating section 41 closer to the first terminal block 20, increases the minimum distance between the first heating section 41 and the third heating section 43, avoiding the formation of heat concentration points around the third heating section 43. Thus, this embodiment can avoid excessive heat in the third heating section 43 due to the presence of multiple heating sections (first heating section 41) around it, thereby preventing excessive heat concentration on the strip heating element 40.

[0089] It should be noted that, referring to Figure 3 As shown, in this embodiment, the first heating segment 41 is arranged adjacent to the first terminal block 20. When the strip heating element 40 includes multiple heating segments, the first heating segment 41 may not be arranged adjacent to the first terminal block 20. Therefore, in one embodiment, the first heating segment 41 and the third heating segment 43 are arranged adjacent to each other, and the minimum distance between the first heating segment 41 and the third heating segment 43 is a first distance H1, which is greater than the maximum distance between the first terminal block 20 and the adjacent heating segment.

[0090] In an optional embodiment, the minimum distance between the first heating section 41 and the third heating section 43 in the first direction is defined as the first distance, and the size of the first distance ranges from 0.3mm to 5mm. This embodiment limits the minimum distance between the first heating section 41 and the third heating section 43 in the first direction to this range, making the heat generated by the strip heating element 40 more evenly distributed on the atomization surface of the porous ceramic substrate 10, avoiding the formation of heating concentration points on any one heating section. Specifically, if the size of the first distance is less than 0.3mm, heat concentration points are easily formed on the first heating section 41 and the third heating section 43, affecting the overall service life of the strip heating element 40. If the size of the first distance is greater than 5mm, the heat generated by the strip heating element 40 is too dispersed, and the e-liquid cannot be fully atomized, resulting in poor atomization.

[0091] Compared to existing technologies, in this embodiment, the first distance between the first heating section 41 and the third heating section 43 in the first direction is 0.05mm-0.2mm greater than the conventional size in existing technologies. Without affecting the atomization effect, the heat distribution generated by the strip-shaped heating element 40 is more uniform.

[0092] In one embodiment, refer to Figure 3 As shown, the porous ceramic substrate 10 includes an atomizing surface, and the strip heating element 40 is disposed on the atomizing surface; the dimension of the atomizing surface in the first direction is a first dimension, and the ratio between the first distance and the first dimension is in the range of 1:3 to 1:15.

[0093] This embodiment limits the minimum spacing between two adjacent heating sections to the size ratio of the atomization surface in the first direction, so that the strip heating element 40 can be more evenly distributed on the atomization surface.

[0094] Specifically, if the ratio between the first distance and the first dimension is less than 1:15, the overall size of the first distance is small, and heat concentration points are easily formed on the first heating section 41 and the third heating section 43. If the ratio between the first distance and the first dimension is greater than 1:3, the size of the first distance is too large, and the heat generated by the strip heating element 40 is too dispersed, resulting in poor atomization of the e-liquid.

[0095] In one embodiment, refer to Figure 3 As shown, the second heating section 42 and the third heating section 43 extend along the second direction of the porous ceramic substrate 10, and the second heating section 42 bends toward the direction of the second terminal block 30;

[0096] The minimum distance between the second heating section 42 and the third heating section 43 in the first direction is the second distance; the second distance is greater than the maximum distance between the second heating section 42 and the second terminal block 30 in the first direction.

[0097] By increasing the minimum distance between the second heating section 42 and the third heating section 43, the heat distribution generated by the strip-shaped heating element is made more uniform, improving the heating uniformity of the e-liquid. To further improve the evenness of the heat distribution on the porous ceramic substrate 10 generated by the strip-shaped heating element 40, in this embodiment, referring to... Figure 3 As shown, the minimum distance between the second heating segment 42 and the third heating segment 43 in the first direction is defined as the second distance H2; the second distance H2 is greater than the maximum distance between the second heating segment 42 and the second terminal block 30 in the first direction. That is, in this embodiment, the second heating segment 42 is bent towards the second terminal block 30, such that the minimum distance between the second heating segment 42 and the third heating segment 43 in the first direction is greater than the maximum distance between the second heating segment 42 and the second terminal block 30 in the first direction.

[0098] It should be noted that, referring to Figure 3 As shown, in this embodiment, the second heating segment 42 is arranged adjacent to the second terminal block 30. When the strip heating element 40 includes multiple heating segments, the second heating segment 42 may not be arranged adjacent to the second terminal block 30. Therefore, in one embodiment, the first heating segment 41 and the third heating segment 43 are arranged adjacent to each other, and the minimum distance between the second heating segment 42 and the third heating segment 43 is a second distance H2, which is greater than the maximum distance between the second terminal block 30 and the adjacent heating segment.

[0099] In one embodiment, the porous ceramic substrate 10 includes an atomizing surface, and the strip heating element 40 is disposed on the atomizing surface; the dimension of the atomizing surface in the first direction is a first dimension, and the ratio between the second distance and the first dimension is in the range of 1:3 to 1:15.

[0100] This embodiment limits the minimum spacing between two adjacent heating sections to the size ratio of the atomization surface in the first direction, so that the strip heating element 40 can be more evenly distributed on the atomization surface.

[0101] Specifically, if the ratio between the second distance and the first dimension is less than 1:15, the overall size of the second distance is small, making it easy for heat to concentrate on the second heating section 42 and the third heating section 43. If the ratio between the second distance and the first dimension is greater than 1:3, the size of the second distance is too large, and the heat generated by the strip heating element 40 is too dispersed, resulting in poor atomization of the e-liquid.

[0102] In one embodiment, refer to Figure 3 As shown, the first heating section 41 is located on the first side of the third heating section 43 in the first direction, and the second heating section 42 is located on the second side of the third heating section 43 in the first direction.

[0103] The strip heating element 40 includes a first heating section 41, a second heating section 42, and a third heating section 43. In other words, the strip heating element 40 simultaneously has a first heating section 41 and a second heating section 42. The first heating section 41 is closer to the first terminal block 20 than the second heating section 42; the second heating section 42 is closer to the second terminal block 30 than the first heating section 41. For example, see... Figure 2 and Figure 3 As shown, the first heating section 41 is close to the left side of the porous ceramic substrate 10, and the second heating section 42 is close to the right side of the porous ceramic substrate 10.

[0104] In the prior art, the third heating section 43 has a first heating section 41 and a second heating section 42 on both sides, and the distance between the third heating section 43 and the first heating section 41 is small. Similarly, the distance between the third heating section 43 and the second heating section 42 is small. Therefore, heat concentration points easily appear on the third heating section 43, affecting the service life of the strip heating element 40 and the porous ceramic substrate 10.

[0105] To avoid heat concentration points on the third heating section 43, the first heating section 41, and the second heating section 42, and to improve the service life of the strip heating element 40 and the porous ceramic substrate 10, in this embodiment, the first heating section 41 is configured as an arc-shaped segment, bending towards the first terminal block 20 to increase the first distance between the first heating section 41 and the third heating section 43. Simultaneously, in this embodiment, the second heating section 42 is configured as an arc-shaped segment, bending towards the second terminal block 30 to increase the second distance between the second heating section 42 and the third heating section 43.

[0106] This embodiment increases the first distance between the first heating section 41 and the third heating section 43, and increases the second distance between the second heating section 42 and the third heating section 43, so that the heat generated by the strip heating element 40 is partially uniform.

[0107] In one embodiment, refer to Figure 3 As shown, the minimum width of the strip heating element 40 is the first width, and the maximum width of the first terminal block 20 in the first direction is the second width; the ratio of the second width to the first width is 3:1 to 10:1.

[0108] In a preferred embodiment, the distance between the middle portions of the first heating segment 41 and the third heating segment 43 is the largest in the first direction, and / or the distance between the middle portions of the second heating segment 42 and the third heating segment 43 is the largest in the first direction. In practical applications, the middle portions of the first heating segment 41, the second heating segment 42, and the third heating segment 43 are approximately located at the center of the heating element 40, where the heat generation is more concentrated than at other more distant locations. Therefore, increasing the distance at these locations can reduce or eliminate local hot spots.

[0109] Specifically, the strip-shaped heating element 40 is a heat-generating component, and the heat it generates is used to atomize the e-liquid. Ideally, all the heat generated by the strip-shaped heating element can be used to atomize the e-liquid, ensuring that the e-liquid is fully atomized. However, due to the sealed connection between the components, the heat generated by the strip-shaped heating element 40 will dissipate; and because the first and second wiring pads 20 and 30 are heat-conducting components, the heat generated by the strip-shaped heating element 40 will also dissipate. This reduces the effective utilization rate of the generated heat.

[0110] To improve the efficient utilization of heat generated by the strip heating element 40, this embodiment limits the maximum width of the first connector 20. The maximum width of the first connector 20 is limited to 3 to 10 times the minimum width of the strip heating element 40, thereby reducing the surface area of ​​the first connector 20. With a reduced surface area, less heat is lost from the first connector 20, and the heat generated by the strip heating element 40 can be more effectively used for atomizing e-liquid, thus improving the efficient utilization of heat.

[0111] In one specific embodiment of this invention, when the maximum width of the first connector 20 is less than three times the width of the strip heating element 40, the connection strength between the first connector 20 and the first electrode 13 deteriorates, and the electrical connection between the first connector 20 and the first electrode 13 weakens. When the maximum width of the first connector 20 is greater than ten times the width of the strip heating element 40, the heat loss through the first connector 20 is significant, the effective utilization rate of the heat generated by the strip heating element 40 decreases, and the effectively utilized heat is insufficient to atomize the e-liquid in the atomization chamber. This embodiment limits the maximum width of the first connector 20 to three to ten times the width of the strip heating element 40. Without affecting the connection strength between the first connector 20 and the first electrode 13, it improves the effective utilization rate of the heat generated by the strip heating element 40. Within a predetermined time, the heat generated by the strip heating element 40 can fully atomize the e-liquid in the chamber, preventing residual e-liquid in the atomization chamber.

[0112] In one embodiment, refer to Figure 3 As shown, the first terminal block 20 includes a first connecting part 21 and a second connecting part 22.

[0113] One end of the first connecting part 21 is connected to the second connecting part 22.

[0114] The other end of the first connecting portion 21, which is away from the second connecting portion 22, is connected by a first arc segment 23.

[0115] Along the second direction and in the direction away from the first connecting portion 2, the width of the second connecting portion 22 gradually decreases in the first direction.

[0116] Specifically, the first terminal block 20 includes a first connecting portion 21 and a second connecting portion 22. One end of the second connecting portion 22 is connected to one end of the first connecting portion 21, and the other end of the second connecting portion 22 is connected to the first connecting segment 46.

[0117] The other end of the first connecting portion 21, away from the second connecting portion 22, is connected by a first arc segment 23. For example, the first arc segment 23 curves toward the second edge 12, and the first arc segment 23 is a smooth transition segment. In this embodiment, by changing the connection method of the two sides of the first connecting portion 21, the overall surface area of ​​the first terminal block 20 can be reduced to a certain extent.

[0118] This embodiment gradually reduces the width of the second connecting portion 22 in the first direction. On one hand, with the maximum width of the first terminal block 20 set, the surface area of ​​the first terminal block 20 can be reduced, improving the effective utilization rate of the heat generated by the strip heating element 40. On the other hand, by gradually reducing the width of the second connecting portion 22 in the first direction, a better transition is made between the left end of the first connecting segment 46 and the first terminal block 20, which not only avoids a sudden temperature change between the first connecting segment 46 and the first terminal block 20, but also strengthens the connection between the first connecting segment 46 and the first terminal block 20.

[0119] In one embodiment, refer to Figure 3 As shown, the heating component of the atomizer includes a first electrode 13, and a first connecting portion 21 is disposed around the first electrode 13 and electrically connected to the first electrode 13; the surface area of ​​the first electrode 13 is a first surface area, the surface area of ​​the first connecting portion 21 is a second surface area, and the ratio of the second surface area to the first surface area is in the range of 1:1 to 5:1.

[0120] In this embodiment, the first connecting portion 21 contacts and connects to the first electrode 13. This embodiment limits the overall surface area of ​​the first terminal block 20 by limiting the size of the surface area of ​​the first connecting portion 21.

[0121] In this embodiment, the surface area of ​​the first electrode 13 disposed on the porous ceramic substrate 10 is defined as the first surface. Since the first connecting portion 21 surrounds and is electrically connected to the first electrode 13, the surface area of ​​the first connecting portion 21 is defined as the second surface area, and the ratio of the second surface area to the first surface area is limited to a range of 1:1 to 5:1, thereby further reducing the overall surface area of ​​the first terminal block 20. Specifically, when the ratio of the second surface area to the first surface area is less than 1:1, for example, when the second surface area is half the first surface area, the connection strength between the first terminal block 20 and the first electrode 13 deteriorates. When the ratio of the second surface area to the first surface area is greater than 5:1, for example, when the second surface area is 8 times the first surface area, the surface area of ​​the first terminal block 20 is larger, the heat loss of the first terminal block 20 increases, and the effective utilization rate of the heat generated by the strip heating element 40 decreases.

[0122] This embodiment improves the shape of the first terminal block 20. At the same time, it limits the surface area of ​​the first terminal block 20, thereby reducing the surface area of ​​the first terminal block 20.

[0123] Similarly, the heating component of the atomizer includes a second electrode 14, and a second terminal block 30 is electrically connected to the second electrode 14. The surface area of ​​the second terminal block 30 is limited to reduce the surface area of ​​the second terminal block 30, thereby improving the effective utilization rate of heat.

[0124] In one embodiment, refer to Figure 3 As shown, the minimum width of the strip heating element 40 is the first width, and the maximum width of the second terminal block 30 in the first direction is the second width; the ratio of the second width to the first width is 3:1 to 10:1.

[0125] To improve the efficient utilization of heat generated by the strip heating element 40, this embodiment limits the maximum width of the second connector 30. The maximum width of the second connector 30 is limited to 3 to 10 times the minimum width of the strip heating element 40, thereby reducing the surface area of ​​the second connector 30. With a reduced surface area, less heat is lost from the second connector 30, and the heat generated by the strip heating element 40 can be more effectively used for atomizing e-liquid, thus improving the efficient utilization of heat.

[0126] In one embodiment, refer to Figure 3 As shown, the second terminal block 30 includes a third connecting part 31 and a fourth connecting part 32.

[0127] One end of the third connecting part 31 is connected to the fourth connecting part 32.

[0128] The other end of the third connecting part 31, which is away from the fourth connecting part 32, is connected by a second arc segment 33.

[0129] Along the second direction and in a direction away from the third connecting portion 31, the width of the fourth connecting portion 32 gradually decreases in the first direction.

[0130] Specifically, the second terminal block 30 includes a third connecting portion 31 and a fourth connecting portion 32. One end of the fourth connecting portion 32 is connected to one end of the third connecting portion 31, and the other end of the fourth connecting portion 32 is connected to the second connecting segment 47.

[0131] The other end of the third connecting portion 31, away from the fourth connecting portion 32, is connected by a second arc segment 33. For example, the second arc segment 33 curves toward the second edge 12, and the first arc segment 23 is a smooth transition segment. In this embodiment, by changing the connection method of the two sides of the third connecting portion 31, the overall surface area of ​​the second terminal block 30 can be reduced to a certain extent.

[0132] This embodiment gradually reduces the width of the fourth connecting portion 32 in the first direction. On one hand, with the maximum width of the second terminal block 30 set, the surface area of ​​the second terminal block 30 can be reduced, improving the effective utilization rate of the heat generated by the strip heating element 40. On the other hand, by gradually reducing the width of the fourth connecting portion 32 in the first direction, a better transition is made between the left end of the second connecting segment 47 and the second terminal block 30, not only avoiding abrupt temperature changes between the second connecting segment 47 and the second terminal block 30, but also strengthening the connection between the second connecting segment 47 and the second terminal block 30.

[0133] In one embodiment, refer to Figure 3 As shown, the porous ceramic matrix 10 has a first edge 11 and a second edge 12 that extend along a first direction and are spaced apart in a second direction.

[0134] The strip heating element 40 includes a first bent section 44 that bends toward the second edge 12. One end of the first bent section 44 is connected to the first heating section 41, and the other end of the first bent section 44 is connected to the third heating section 43.

[0135] Typically, in specific implementations, the strip heating element 40 can be integrally formed, and the connection position between the first bent section 44 and the first heating section 41 can be the position where the radius of curvature of the curved strip heating element 40 changes the most. This also applies to the connection positions of the second bent section 45, the first connecting section 46, the second connecting section 47 and the corresponding heating sections described below in this application, and will not be described separately.

[0136] The strip heating element 40 includes a first connecting section 46 bent toward the first edge 11, one end of the first connecting section 46 is connected to the first terminal block 20, and the other end of the first connecting section 46 is connected to the first heating section 41;

[0137] The distance between the first bent segment 44 and the first edge 11 in the second direction is greater than the distance between the first connecting segment 46 and the second edge 12 in the second direction.

[0138] Specifically, the strip heating element 40 has a first bent section 44. The first bent section 44 bends toward the location of the second edge 12, that is, both ends of the first bent section 44 extend toward the location of the second edge 12, for example, as... Figure 2 As shown, the opening of the first bent segment 44 is positioned opposite to the second edge 12.

[0139] By setting the first bending section 44, the heating area can be expanded, improving the uniformity of e-liquid heating. Since the first bending section 44 is connected to the third heating section 43, the first bending section 44 is located on the first side of the third heating section 43 in the second direction. The heat generated by the first heating section 41, the third heating section 43, and the first bending section 44 affects each other.

[0140] Since one end of the first connecting section 46 is connected to the first terminal block 20 and the other end is connected to the first heating section 41, the heat generated by the first connecting section 46 and the first heating section 41 affects each other.

[0141] Therefore, the number of heating sections affecting the temperature around the first bending section 44 is greater than the number of heating sections affecting the temperature around the first connecting section 46.

[0142] Therefore, this embodiment limits the distance between the first bending segment 44 and the first edge 11 in the second direction to be greater than the distance between the first connecting segment 46 and the second edge 12 in the second direction, thereby reducing the temperature at the first edge 11 and the second edge 12. This not only avoids affecting the lifespan of the structure near the first edge 11 and the second edge 12 on the atomizer, but also prevents the user's hands from being burned by the high temperature near the first edge 11 and the second edge 12 when using the atomizer.

[0143] It should be noted that the shape of the first edge 11 can be either a straight line or an arc, and is not limited here.

[0144] Furthermore, the number of first bending segments 44 is at least one. That is to say, the number of first bending segments 44 can be one, two, or more, and the total number can be odd or even. There is no limitation on the number of first bending segments 44 here.

[0145] This embodiment increases the distance between the first bending segment 44 and the first edge 11, avoiding excessively high temperatures at the edge of the porous ceramic substrate 10, thereby extending the lifespan of the atomizer and improving the user's hand comfort when using the atomizer.

[0146] In one embodiment, refer to Figure 3 As shown, the first connecting segment 46 has a semi-circular structure and is inclined in a first direction away from the first terminal block 20.

[0147] Specifically, the first connecting segment 46 is inclined away from the first terminal block 20 in the first direction. That is, the first connecting segment 46 is positioned closer to the second bending segment 45 in the first direction.

[0148] For example, the first connecting segment 46 has a semi-circular structure and is symmetrically arranged about the central axis, which is an inclined line. The heat generated by the first connecting segment 46 and the heat generated by the second bending segment 45 affect each other. When the first connecting segment 46 is inclined towards the second bending segment 45, the heat distribution of the first connecting segment 46 and the second bending segment 45 and their surroundings is more uniform.

[0149] In one embodiment, refer to Figure 3 As shown, the porous ceramic matrix 10 has a first edge 11 and a second edge 12 that extend along a first direction and are spaced apart in a second direction.

[0150] The strip heating element 40 includes a second bent section 45 that bends toward the first edge 11. One end of the second bent section 45 is connected to the third heating section 43, and the other end of the second bent section 45 is connected to the second heating section 42.

[0151] The strip heating element 40 includes a second connecting section 47 bent toward the second edge 12. One end of the second connecting section 47 is connected to the second terminal block 30, and the other end of the second connecting section 47 is connected to the second heating section 42.

[0152] The distance between the second bent segment 45 and the second edge 12 in the second direction is greater than the distance between the second connecting segment 47 and the first edge 11 in the second direction.

[0153] Specifically, the strip heating element 40 has a second bent section 45. The second bent section 45 bends toward the location of the first edge 11, that is, both ends of the second bent section 45 extend toward the location of the first edge 11, for example, as... Figure 3 As shown, the opening of the second bent segment 45 is positioned opposite to the first edge 11.

[0154] By incorporating the second bending section 45, the heating area can be expanded, improving the uniformity of e-liquid heating. Since the second bending section 45 is connected to the third heating section 43, it is located on the second side of the third heating section 43 in the second direction. The heat generated by the first heating section 41, the third heating section 43, and the second bending section 45 influences each other.

[0155] Since one end of the second connecting section 47 is connected to the second terminal block 30 and the other end is connected to the second heating section 42, the heat generated by the second connecting section 47 and the second heating section 42 affects each other.

[0156] Therefore, the number of heating sections affecting the temperature around the second bending section 45 is greater than the number of heating sections affecting the temperature around the second connecting section 47.

[0157] Therefore, this embodiment limits the distance between the second bending segment 45 and the second edge 12 in the second direction to be greater than the distance between the second connecting segment 47 and the first edge 11 in the second direction, thereby reducing the temperature at the first edge 11 and the second edge 12. This not only avoids affecting the lifespan of the structure near the first edge 11 and the second edge 12 on the atomizer, but also prevents the user's hands from being burned by the high temperature near the first edge 11 and the second edge 12 when using the atomizer.

[0158] It should be noted that the shape of the first edge 11 can be either a straight line or an arc, and is not limited here.

[0159] Furthermore, the number of second bend segments 45 is at least one. That is to say, the number of second bend segments 45 can be one, two, or more, and the total number can be odd or even. There is no limitation on the number of second bend segments 45 here.

[0160] This embodiment increases the distance between the second bending segment 45 and the second edge 12, avoiding excessively high temperatures at the edge of the porous ceramic substrate 10, thereby extending the lifespan of the atomizer and improving the user's hand comfort when using the atomizer.

[0161] In one embodiment, refer to Figure 3 As shown, the second connecting section 47 has a semi-circular structure and is inclined in the first direction away from the second terminal block 30.

[0162] Specifically, the second connecting segment 47 is inclined away from the second terminal block 30 in the first direction. That is, the second connecting segment 47 is positioned closer to the first bending segment 44 in the first direction.

[0163] For example, the second connecting segment 47 has a semi-circular structure and is symmetrically arranged about the central axis, which is an inclined line. The central axis of the second connecting segment 47 is parallel to the central axis of the first connecting segment 46. The heat generated by the second connecting segment 47 and the heat generated by the first bending segment 44 affect each other. When the second connecting segment 47 is inclined towards the first bending segment 44, the heat distribution of the second connecting segment 47, the first bending segment 44 and their surroundings is more uniform.

[0164] In one embodiment, refer to Figure 3 As shown, the length of the first heating section 41 is less than the length of the first connecting section 46.

[0165] For ease of description, the extension direction of the first heating section 41 can be defined as extending in the vertical direction, and the first heating section 41 extends in an arc shape in the second direction.

[0166] The lower end of the first heating section 41 can be electrically connected to the first connecting section 46, and the upper end of the first heating section 41 can be electrically connected to the first bending section 44. The first connecting section 46 bends toward the first edge 11 in the second direction, so that the first connecting section 46, the first heating section 41 and the first bending section 44 can cooperate to form an "S" shaped structure, thereby allowing the strip heating element 40 to be evenly distributed on the porous ceramic substrate 10, rather than being concentrated in a certain area.

[0167] In addition, the length of the first heating section 41 may be less than the length of the first connecting section 46, or less than the length of the first bending section 44, or the length of the first heating section 41 may be less than the lengths of both the first connecting section 46 and the first bending section 44.

[0168] By providing a first heating section 41 in the strip heating element 40, the strip heating element 40 can be more widely distributed on the porous ceramic substrate 10, thereby making the heat emitted by the strip heating element 40 more uniformly distributed.

[0169] Furthermore, by setting the length of the first heating section 41 to be less than the length of the first connecting section 46 or the first bending section 44, on the one hand, the minimum distance between the first bending section 44 and the first edge 11 can be increased by shortening the length of the first heating section 41, thereby achieving the effect of reducing the temperature of the first edge 11. On the other hand, by shortening the length of the first heating section 41 and increasing the length of the first connecting section 46 or the first bending section 44, the distribution of the strip heating element 40 in the left-right direction can be more relaxed, avoiding the strip heating element 40 from concentrating in a certain area and causing excessive local heat.

[0170] In one embodiment, the width of the first connecting segment 46 gradually decreases along the direction from the first terminal block 20 to the first heating segment 41.

[0171] The minimum width of the first connecting section 46 is the same as the width of the first heating section 41;

[0172] The maximum width of the first connecting section 46 is the same as the minimum width of the first terminal block 20.

[0173] In other words, such as Figure 3 As shown, a first connecting section 46 is also provided between the left end of the strip heating element 40 and the first terminal block 20. The first connecting section 46 is defined as an arc-shaped segment. That is, during the heating and cooling process, due to the difference in expansion rates between the strip heating element 40 and the porous ceramic substrate 10, each part of the strip heating element 40 will be compressed or stretched in the tangential direction of the curve of the strip heating element 40. The use of an arc-shaped segment ensures that the force on each part of the first connecting section 46 will not be superimposed in one direction, thereby reducing the risk of the first connecting section 46 breaking under large temperature differences.

[0174] Therefore, by setting the first connecting segment 46 as an arc-shaped segment, it is not only convenient to connect the first terminal block 20 with the strip heating element 40, but also to effectively prevent the strip heating element 40 from breaking due to excessive temperature difference between it and the first terminal block 20.

[0175] This embodiment adopts a gradually decreasing width approach to achieve a better transition between the left end of the first connecting segment 46 and the first terminal block 20. This not only avoids a sudden temperature change between the first connecting segment 46 and the first terminal block 20, but also strengthens the connection between the first connecting segment 46 and the first terminal block 20.

[0176] In some specific embodiments of this application, the inner radius of curvature of the first connecting segment 46 is greater than 0.3 mm. In other words, by using a larger radius of curvature, the forces at each point of the first connecting segment 46 will not be superimposed in one direction, thereby reducing the risk of the strip heating element 40 breaking under large temperature differences.

[0177] In one embodiment, the strip heating element 40 includes a second connecting segment 47, one end of which is connected to the second terminal block 30, and the other end of which is connected to the second heating segment 42; the structure of the second connecting segment 47 is the same as that of the first connecting segment 46, and the extension direction of the second connecting segment 47 is opposite to that of the first connecting segment 46 in the second direction.

[0178] For example, such as Figure 3As shown, a first connecting section 46 is provided between the left end of the strip heating element 40 and the first terminal block 20, and a second connecting section 47 is provided between the right end of the strip heating element 40 and the second terminal block 30. The structure of the second connecting section 47 is the same as that of the first connecting section 46. The extension direction of the first connecting section 46 is bent towards the location of the first edge 11, and the extension direction of the second connecting section 47 is bent towards the location of the second edge 12. Similar to the first connecting section 46, the minimum width of the second connecting section 47 is the same as the width of the strip heating element 40; the maximum width of the second connecting section 47 is the same as the minimum width of the second terminal block 30. The second connecting section 47 can also be an arc-shaped segment, which will not be described in detail here.

[0179] In one embodiment, refer to Figure 3 As shown, the width of the third heating section 43 is greater than the width of the first heating section 41 or the width of the second heating section 42.

[0180] Since the outer side of the third heating section 43 is surrounded by multiple heating sections (first bending section 44, second bending section 45, first heating section 41 and second heating section 42), in order to prevent the heat near the third heating section 43 from being too high, the width of the third heating section 43 can be widened, thereby reducing the resistance of the third heating section 43 and ultimately reducing the heat of the third heating section 43, thus further effectively preventing the heat of the third heating section 43 from being too concentrated.

[0181] Therefore, this embodiment avoids excessive heat concentration in the third heating section through two aspects. While limiting the distance between the first heating section 41 and the third heating section 43, this embodiment further limits the width of the third heating section, thereby effectively preventing excessive heat concentration in the third heating section 43.

[0182] In some specific embodiments of this application, the length of the first heating section 41 is less than the length of the first connecting section 46, the length of the second heating section 42 is less than the length of the second connecting section 47, and the radii of curvature of both the first connecting section 46 and the second connecting section 47 are relatively large. This helps to ensure a reasonable spacing between the first heating section 41, the third heating section 43, and the second heating section 42. It also helps to reduce the temperature difference between different heating sections, resulting in more uniform temperature and improved atomization effect.

[0183] In one embodiment, refer to Figure 3 As shown, the strip heating element 40 includes a first connecting section 46, one end of which is connected to the first terminal block 20, and the other end of which is connected to the first heating section 41.

[0184] The first connecting segment 46 has an upper edge 461 and a lower edge 462 that are spaced apart along the second direction. The first connecting portion 21 of the first terminal block 20 has a first side 211 and a second side 212 that extend along the second direction and are spaced apart along the first direction. The first side 211 is close to the first connecting segment 46, and the second side 212 is located on the side of the first side 211 that is away from the first connecting segment 46.

[0185] The second connecting portion 22 of the first terminal block 20 has an arc-shaped first transition section 221 and an arc-shaped second transition section 222. The first side 211 is connected to the upper edge 461 through the arc-shaped first transition section 221, and the second side 212 is connected to the lower edge 462 through the arc-shaped second transition section 222. The length of the second transition section 222 is greater than the length of the first transition section 221.

[0186] The length of the second transition section 222 is greater than the length of the first transition section 221, and the radius of curvature of the second transition section 222 is smaller than that of the first transition section 221. This is more conducive to the smooth connection between the second side 212 of the first terminal block 20 and the first connecting section 46, and further reduces the rate of temperature difference change.

[0187] This embodiment can further reduce the cumulative linear deformation and further avoid the first terminal block 20 and the first connecting section 46 from being prone to breakage due to temperature difference and different expansion rates with the porous ceramic matrix 10.

[0188] In this embodiment, the first connecting part 21, the second connecting part 22 and the first arc segment 23 are an integral structural component. During the production and processing, the design of the integral molding component facilitates casting, which can not only improve efficiency, but also save production costs.

[0189] In this embodiment, the first arc segment 23 is an arc-shaped bend. The maximum width of the first arc segment 23 in the first direction is the same as the width of the first connecting part 21, which can further reduce the surface area of ​​the first terminal block 20. As a heat dissipation component, the smaller the surface area of ​​the first terminal block 20, the less heat it loses. The heat generated by the strip heating element 40 can be effectively utilized to the maximum extent (for atomization), thus improving the effective utilization rate of heat.

[0190] In one embodiment, refer to Figure 3 As shown, the strip heating element 40 extends from the first terminal block 20 to the second terminal block 30.

[0191] Specifically, the first connecting segment 46, the first heating segment 41, the first bending segment 44, the third heating segment 43, the second bending segment 45, the second heating segment 42, and the second connecting segment 47 of the strip heating element 40 are all arc-shaped segments, and adjacent arc-shaped segments are smoothly connected by curves. Compared with the prior art, this avoids the accumulation of linear deformation and further prevents the first terminal block 20, the second terminal block 30, and the strip heating element 40 from being prone to breakage due to temperature differences and differences in expansion rates with the porous ceramic substrate 10.

[0192] In addition, the first connecting segment 46, the first heating segment 41, the first bending segment 44, the third heating segment 43, the second bending segment 45, the second heating segment 42, and the second connecting segment 47 of the strip heating element 40 are all arc-shaped segments. Adjacent arc-shaped segments are smoothly connected by curves. In order to avoid heat concentration, more heating segments can be set on the porous ceramic substrate 10, which improves the uniformity of heat distribution without affecting the atomization effect.

[0193] In one embodiment, the strip heating element 40 is a centrosymmetric body. By adopting a centrosymmetric structure, not only is it easier to process and produce, but it also helps to achieve uniformity of heat emitted by the strip heating element 40.

[0194] In some specific embodiments of this application, the linear length of the strip heating element 40 can be designed according to the power density, and the total length of the strip heating element 40 is between 1mm and 20mm. It should be noted that the total length of the strip heating element 40 is the sum of the lengths of the first connecting segment 46, the first heating segment 41, the first bending segment 44, the third heating segment 43, the second bending segment 45, the second heating segment 42, and the second connecting segment 47.

[0195] In addition, in order to ensure the uniformity of the overall structure of the strip heating element 40 on the porous ceramic substrate 10, according to one embodiment of this application, the width of the strip heating element 40 from the edge of the porous ceramic substrate 10 can be in the range of 0.2mm to 5mm.

[0196] The total resistance of the strip heating element 40 can be adjusted by changing its width. According to one embodiment of this application, the width of the strip heating element 40 can range from 0.1 mm to 5 mm.

[0197] The total resistance of the strip heating element 40 can also be adjusted by changing its thickness or conductivity. According to one embodiment of this application, the thickness of the strip heating element 40 ranges from 0.01 mm to 1 mm. It should be noted that the thicker the strip heating element 40, the lower the total resistance, the less heat is generated, and thus the less vapor is produced. In other words, the total resistance of the strip heating element 40 can be adjusted by changing its thickness or resistivity, and its power can be adjusted by the control circuit board to make the e-liquid atomization effect more stable.

[0198] Furthermore, the heating assembly 100 of the atomizer according to the embodiments of this application employs strip-shaped heating elements 40 connected in series. The arrangement and structure of the strip-shaped heating elements 40 can be designed based on the analysis of their heating and heat transfer. Thermal analysis shows that the design of the strip-shaped heating elements 40 must consider not only heating but also heat conduction. A reasonable arrangement combined with designs using different widths can effectively prevent the occurrence of localized hot spots and hot zones, greatly reducing the possibility of burnt flavors; it can also effectively conduct heat, preventing the heating conductive layer or atomizing core from experiencing lifespan degradation due to excessively rapid heating. Its total resistance can be adjusted by changing the thickness and resistivity of the heating conductive layer, and its power can be adjusted by controlling the circuit board, making the e-liquid atomization effect more stable.

[0199] According to a second aspect of this application, an atomizer is provided. It atomizes the heating assembly 100 of the atomizer described in any of the above embodiments. Since the heating assembly 100 of the atomizer according to the embodiments of this application has the above-described technical effects, the atomizer according to the embodiments of this application also has the above-described technical effects. Ultimately, the service life of the atomizer can be extended.

[0200] Other configurations and operations of the atomizer according to the embodiments of this application are known to those skilled in the art and will not be described in detail here.

[0201] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0202] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
