[0051] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0052] Please also read Figures 1 to 4 , Figure 1 A three-dimensional structural diagram of the atomizer core provided in some embodiments of the present application. Figure 2 A partial three-dimensional structural diagram of the heating structure 10 provided in some embodiments of the present application. Figure 3 A partial schematic diagram of a heating structure 10 provided in some embodiments of the present application, specifically Figure 2 Schematic diagram of the structure shown in the third direction Z. Figure 4 for Figure 3 The enlarged view of A in the figure. The heating structure 10 provided in the embodiment of the present application includes a heating body 1. The heating body 1 includes a plurality of first heating elements 11 and a plurality of heating components 12, and the heating components 12 are connected between two adjacent first heating elements 11, so that the plurality of heating components 12 are sequentially connected and conducted through the first heating elements 11. The heating components 12 and the two adjacent first heating elements 11 are arranged to form a first through hole 101.

[0053] It should be noted that the heating body 1 is a component with conductive properties, specifically a resistive load, so that the heating body 1 can be energized, and the heating body 1 can generate heat to generate heat when energized, and the heat generated by the heating body 1 is used to heat the atomized liquid. It can be understood that the heating body 1 is the part of the heating structure 10 for current to pass through, so that the heating body 1 is the main heating part of the heating structure 10.

[0054] It can be understood that the plurality of first heating elements 11 are distributed in sequence and at intervals. For ease of description, it is defined that the plurality of first heating elements 11 are distributed in sequence and at intervals along the first direction X, and two adjacent first heating elements 11 refer to two first heating elements 11 adjacent to each other along the first direction X. The first direction X is the approximate distribution direction of the plurality of first heating elements 11, and the first direction X is the direction of the double arrow.

[0055] As an example, Figure 2 and Figure 3 As shown, a plurality of first heat generating elements 11 are sequentially spaced and distributed along the first direction X, and a plurality of heat generating components 12 are sequentially spaced and distributed along the first direction X.

[0056] It can be understood that both the first heating element 11 and the heating assembly 12 are components with conductive properties, specifically, both are resistive loads. The heating assembly 12 is connected between two adjacent first heating elements 11, so that multiple heating assemblies 12 are connected and conducted in sequence through the first heating element 11, which means that a heating assembly 12 is connected between any two adjacent first heating elements 11, so that each first heating element 11 and each heating assembly 12 are alternately connected and conducted. Based on this, when the heating structure 10 is powered on, the current can alternately pass through each first heating element 11 and each heating assembly 12, so that the first heating element 11 and the heating assembly 12 can generate heat when powered on to generate heat for heating the atomized liquid to atomize and form an aerosol.

[0057] It should be noted that each first heating element 11 and each heating assembly 12 are alternately connected and turned on, so that current can alternately pass through each first heating element 11 and each heating assembly 12, so that the first heating element 11 and the heating assembly 12 are both parts of the heating structure 10 for current to pass through, and are both the main heating parts of the heating structure 10. In this way, the first heating element 11 and the heating assembly 12 are both parts of the heating structure 10 where heat may be concentrated. It can be understood that the heat of the first heating element 11 and the heat of the heating assembly 12 is greater than the heat of other parts of the heating structure 10, so that the heating structure 10 has the problem of local heat concentration and uneven temperature.

[0058] The heating component 12 and the two adjacent first heating elements 11 are surrounded to form a first through hole 101, so that the heating body 1 is formed with a plurality of first through holes 101 distributed at intervals. Based on this, the heating body 1 is a mesh structure, and the first through holes 101 are set through the heating body 1. As an example, the first through hole 101 penetrates the heating body 1 along the third direction Z, and the third direction Z is the approximate penetration direction of the first through hole 101, and the third direction Z is the direction of the double arrow.

[0059] Wherein, the first direction X and the third direction Z intersect. The intersection of the first direction X and the third direction Z means that the first direction X and the third direction Z can form an angle greater than 0° and less than 180°, that is, the first direction X and the third direction Z are not parallel. The first direction X and the third direction Z can be perpendicular to each other, or they can be non-perpendicular. The first direction X and the third direction Z can be directions that intersect on the same plane, or they can be directions on planes that are not parallel to each other, and the projection of the third direction Z on the plane where the first direction X is located can intersect with the first direction X. As an example, the first direction X and the third direction Z are perpendicular.

[0060] Among some possible designs, such as Figures 2 to 4 As shown, the heat-generating component 12 is provided with a first heat-dissipating portion 121 .

[0061] The first heat dissipation part 121 refers to the part of the heating component 12 used for heat dissipation. By providing the first heat dissipation part 121, the heat dissipation effect of the heating component 12 can be improved to a certain extent to reduce the heat of the heating component 12. In this way, it is helpful to improve the temperature uniformity of the heating structure 10.

[0062] Among some possible designs, such as Figure 2 and Figure 3 As shown, a second heat dissipation portion is provided on the first heating element 11 .

[0063] The second heat dissipation part refers to the part of the first heating element 11 used for heat dissipation. By providing the second heat dissipation part, the heat dissipation effect of the first heating element 11 can be improved to a certain extent to reduce the heat of the first heating element 11. In this way, it is helpful to improve the temperature uniformity of the heating structure 10.

[0064] The heating structure 10 provided in the embodiment of the present application is configured with a first heat dissipation portion 121 on the heating component 12 and / or a second heat dissipation portion on the first heating element 11, so that the first heat dissipation portion 121 and / or the second heat dissipation portion can dissipate heat from a heat-concentrated portion of the heating structure 10. This helps to improve the problem of local heat concentration in the heating structure 10, so that the temperature of the heating structure 10 is evenly distributed, and the temperature uniformity of the heating structure 10 is improved, thereby helping to reduce the risk of the heating structure 10 burning, thereby helping to extend the service life of the heating structure 10.

[0065] In some embodiments, the heating body 1 is a metal structure, that is, the first heating element 11 and the heating component 12 are both metal structures.

[0066] Specifically, the heating body 1 can be made of at least one of iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, pure titanium and other metal materials. The heating body 1 made of these materials has fast heating, high thermal efficiency, high strength, certain corrosion resistance and long service life. It can be understood that the first heating element 11 and the heating component 12 can be made of at least one of iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, pure titanium and other metal materials.

[0067] In some embodiments, please refer to Figures 2 to 4 , and combined with other drawings. Multiple heating components 12 are distributed along the first direction X, and the heating component 12 includes two second heating elements 122 distributed along the second direction Y. The opposite ends of each second heating element 122 of the heating component 12 are respectively connected to two adjacent first heating elements 11, and the two second heating elements 122 of the heating component 12 and the two adjacent first heating elements 11 are surrounded to form a first through hole 101. At least part of the heating components 12 also includes a first heat dissipation portion 121 provided on the second heating element 122. The heating body 1 has a first projection parallel to the first direction X and the second direction Y. On the first projection, the projection of the first heat dissipation portion 121 is set to protrude from the projection of the second heating element 122. Among them, the first direction X intersects with the second direction Y.

[0068] It is understandable that at least one heating component 12 may include only two second heating elements 122 without including the first heat dissipation portion 121. At least one heating component 12 may also include the first heat dissipation portion 121 and two second heating elements 122, wherein the first heat dissipation portion 121 is disposed on the second heating element 122.

[0069] It can be understood that the first heat dissipation portion 121 is a portion of the heat-generating component 12 that has thermal conductivity, so that the first heat dissipation portion 121 can conduct heat to disperse the heat on the heat-generating component 12 .

[0070] The second heating element 122 refers to a component with conductive properties, specifically a resistive load. In the two second heating elements 122 of the heating assembly 12, the opposite ends of each second heating element 122 are respectively connected to the two adjacent first heating elements 11, so that the two second heating elements 122 of the heating assembly 12 and the two adjacent first heating elements 11 are surrounded to form the first through hole 101. In addition, the second heating element 122 and the two adjacent first heating elements 11 are also connected. Based on this, the first heating element 11 and the second heating element 122 are alternately connected and turned on. When the heating structure 10 is powered on, the current can alternately pass through the first heating element 11 and the second heating element 122. Specifically, the current can be shunted from the first heating element 11 to the two second heating elements 122 of the heating assembly 12, and then can be converged to the next first heating element 11. In this way, the first heating element 11 and the second heating element 122 can both generate heat to generate heat when powered on, so as to heat the atomized liquid and atomize it to form an aerosol. It can be understood that the second heating element 122 is a portion where the heat of the heating structure 10 may be concentrated.

[0071] The second direction Y intersects the third direction Z. The meaning of the first direction X intersecting the second direction Y and the meaning of the second direction Y intersecting the third direction Z are the same as the meaning of the first direction X intersecting the third direction Z, and are not repeated here. As an example, the first direction X is perpendicular to the third direction Z, the first direction X is perpendicular to the second direction Y, and the second direction Y is perpendicular to the third direction Z.

[0072] in, Figure 3 for Figure 2 The schematic diagram of the structure shown in FIG. 1 and the schematic diagram of the first projection of the heat generating body 1 are Figure 3 The schematic diagrams of the heat generating body 1 of the structure shown in are the same, and the details can be referenced to each other.

[0073] The first projection is parallel to the first direction X and parallel to the third direction Z. When the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y, the first projection is a projection formed by the heating body 1 along the third direction Z. Figure 3 for Figure 2 Schematic diagram of the structure shown in the third direction Z.

[0074] By setting the projection of the first heat dissipation part 121 to protrude from the projection of the second heating element 122 on the first projection, the overall projection area formed by the first heat dissipation part 121 and the second heating element 122 is increased on the first projection, which helps to disperse heat and improve the temperature uniformity of the heating structure 10.

[0075] For the convenience of description, it is defined that the second heat generating element 122 has a length direction a and a width direction b, and both the length direction a and the width direction b are parallel to the first projection.

[0076] The second heating element 122 may extend in a linear direction, that is, the extension direction of the second heating element 122 is a linear direction; the second heating element 122 may also extend in a non-linear direction, that is, the extension direction of the second heating element 122 is a non-linear direction.

[0077] When the extension direction of the second heating element 122 is a non-linear direction, the length directions a of different parts of the second heating element 122 may be different, that is, the length direction a of a certain part of the second heating element 122 is the specific extension direction of the part. When the extension direction of the second heating element 122 is a non-linear direction, the width directions b of different parts of the second heating element 122 may be different. For example, Figure 2 and Figure 3 As shown, the two heating strips 1221 of the second heating element 122 are bent relative to each other, so that the two heating strips 1221 of the second heating element 122 extend in different directions, thereby making the length direction a and width direction b of the two heating strips 1221 of the second heating element 122 different.

[0078] The length direction a and the width direction b are perpendicular to each other, and both the length direction a and the width direction b are perpendicular to the third direction Z.

[0079] In some embodiments, the second heating element 122 is a metal structure. Specifically, the second heating element 122 can be made of at least one of metal materials such as iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, and pure titanium.

[0080] In some embodiments, please refer to Figures 2 to 4 , and in combination with other drawings. The first heat dissipation portion 121 is disposed on the side of the second heat generating element 122 facing the first through hole 101 and the side of the second heat generating element 122 facing away from the first through hole 101 .

[0081] It can be understood that the first heat dissipation portion 121 is provided on the side of the second heating element 122 facing the first through hole 101, that is, the first heat dissipation portion 121 is provided on the hole wall of the first through hole 101. In addition, the first heat dissipation portion 121 is also provided on the side of the second heating element 122 facing away from the first through hole 101. That is, the first heat dissipation portion 121 is provided on both opposite sides of the second heating element 122, so that on the first projection, the projection of the first heat dissipation portion 121 protrudes on both opposite sides of the projection of the second heating element 122.

[0082] Such an arrangement enables the first heat dissipation portions 121 on opposite sides of the second heating element 122 to be used to disperse the heat of the first heating element 11 , thereby helping to better improve the temperature uniformity of the heating structure 10 .

[0083] In some embodiments, please refer to Figures 2 to 4, and combined with other drawings. The second heating element 122 is provided with a first center line L, and the shortest distance between the side of the second heating element 122 facing the first through hole 101 and the first center line L is equal to the shortest distance between the side of the second heating element 122 facing away from the first through hole 101 and the first center line L. The first heat dissipation portion 121 of the second heating element 122 facing the first through hole 101 and the first heat dissipation portion 121 of the second heating element 122 facing away from the first through hole 101 are symmetrically arranged relative to the first center line L.

[0084] It can be understood that the first heat dissipation portions 121 on opposite sides of the second heat-generating element 122 are symmetrically arranged relative to the first center line L.

[0085] Such an arrangement enables the first heat dissipation portions 121 on opposite sides of the second heating element 122 to evenly disperse heat, thereby helping to better improve the temperature uniformity of the heating structure 10 .

[0086] In other embodiments, the second heating element 122 may be provided with the first heat dissipation portion 121 only on the side facing the first through hole 101 . Alternatively, the second heating element 122 may be provided with the first heat dissipation portion 121 only on the side facing away from the first through hole 101 .

[0087] In some embodiments, please refer to Figures 2 to 4 , and combined with other drawings. The second heating element 122 includes two heating strips 1221. One end of the two heating strips 1221 of the second heating element 122 is relatively bent and connected to each other, and the other ends of the two heating strips 1221 of the second heating component 12 are respectively connected to two adjacent first heating elements 11. The four heating strips 1221 of the heating component 12 and the two adjacent first heating elements 11 are arranged to form a first through hole 101. The first heat dissipation portion 121 is arranged on the heating strip 1221, and on the first projection, the projection of the first heat dissipation portion 121 is arranged to protrude from the projection of the heating strip 1221.

[0088] The heating bar 1221 refers to a rib structure with conductive properties. Among them, one end of the two heating bars 1221 of the second heating element 122 is connected to each other so that the two heating bars 1221 of the second heating element 122 are conductive to each other. Among them, the heating bar 1221 is connected to the first heating element 11 so that the heating bar 1221 and the first heating element 11 are conductive. The other ends of the two heating bars 1221 of the second heating component 12 are respectively connected to the two adjacent first heating elements 11 so that the two adjacent first heating elements 11 are conductive through the heating bar 1221. Based on this, when the heating structure 10 is powered on, the current can alternately pass through the first heating element 11 and the heating bar 1221.

[0089] Such arrangement enables the projection of the first through hole 101 on the first projection to be a polygon, which is beneficial to improving the structural stability of the heat generating body 1 .

[0090] Specifically, see Figure 4 , and combined with other drawings. The shortest distance between the side of the heating strip 1221 facing the first through hole 101 and the first center line L is the second distance H5, and the shortest distance between the side of the heating strip 1221 facing away from the first through hole 101 and the first center line L is the third distance H6, and the second distance H5 and the third distance H6 are equal. The heating strip 1221 is provided with a first heat dissipation portion 121 on the side facing the first through hole 101, and the heating strip 1221 is also provided with a first heat dissipation portion 121 on the side away from the first through hole 101.

[0091] The first heat dissipation portion 121 on the side of the heating bar 1221 facing the first through hole 101 and the first heat dissipation portion 121 on the side of the heating bar 1221 facing away from the first through hole 101 are symmetrically arranged relative to the first center line L. That is, the first heat dissipation portions 121 on opposite sides of the heating bar 1221 are symmetrically arranged relative to the first center line L.

[0092] In some embodiments, the heat dissipation strip is a metal structure. Specifically, the heat dissipation strip can be made of at least one of metal materials such as iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, and pure titanium.

[0093] In some embodiments, please refer to Figures 2 to 4 , and in combination with other drawings. A plurality of first heat dissipation parts 121 are arranged at intervals on one side of the heating strip 1221 facing the first through hole 101. The plurality of first heat dissipation parts 121 on this side of the heating strip 1221 are arranged at intervals along the length direction a (referred to as the length direction a) of the heating strip 1221.

[0094] In some embodiments, please refer to Figures 2 to 4 , and in combination with other drawings. A plurality of first heat dissipation parts 121 are arranged at intervals on the side of the heating strip 1221 facing away from the first through hole 101. The plurality of first heat dissipation parts 121 on this side of the heating strip 1221 are arranged at intervals along the length direction a (referred to as the length direction a) of the heating strip 1221.

[0095] With such configuration, the first heat dissipation portion 121 can effectively disperse the heat of the first heating element 11 and improve the problem of local heat concentration.

[0096] In some embodiments, please refer to Figures 2 to 4, and combined with other drawings. The sum of the dimensions of all first heat dissipation parts 121 on the same side of the heating bar 1221 in the length direction a of the heating bar 1221 (referred to as the length direction a) is the first length H1, and the dimension of the heating bar 1221 in the length direction a of the heating bar 1221 is the second length H2. First length H1 / second length H2∈[0.2, 0.5].

[0097] It can be understood that the first length H1 / the second length H2 is ≥ 0.2 and ≤ 0.5, and can specifically be 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, etc.

[0098] Such a configuration ensures that the overall size of the heating component 12 is not too large while the first heat dissipation portion 121 can effectively disperse heat, thereby improving the problem of the resistance of the heating structure 10 being affected by the excessive configuration of the first heat dissipation portion 121 .

[0099] In some embodiments, please refer to Figures 2 to 4 , and combined with other drawings. The heating strips 1221 and the first heating element 11 are distributed along the second direction Y. It can be understood that in the heating component 12, the heating strip 1221 of one of the second heating elements 122 is connected to one end of the first heating element 11 along the second direction Y, and the heating strip 1221 of the other second heating element 122 is connected to the other end of the first heating element 11 along the second direction Y.

[0100] In the length direction a of the heating strip 1221, the distance between the end of the first heat dissipation portion 121 close to the first heating element 11 and the first heating element 11 is a first distance H3, and the size of the heating strip 1221 is a second length H2. First distance H3 / second length H2∈[0,1 / 3].

[0101] It can be understood that the first distance H3 / the second length H2 ≥ 0, that is, the first heat dissipation portion 121 is connected to the first heat generating element 11 at one end close to the first heat generating element 11. In addition, the first distance H3 / the second length H2 ≤ 1 / 3. Specifically, the first distance H3 / the second length H2 can be 0, 1 / 10, 1 / 9, 1 / 8, 1 / 7, 1 / 6, 1 / 5, 1 / 4, 1 / 3, etc.

[0102] Such a configuration enables the first heat dissipation portion 121 to be as close to the first heating element 11 as possible to disperse the heat of the portion of the second heating element 122 close to the first heating element 11, thereby effectively dispersing the heat of the first heating element 11 to improve the problem of local heat concentration, which helps to improve the temperature uniformity of the heating structure 10.

[0103] In some embodiments, please refer to Figures 2 to 4In the first projection, along the direction in which the first heat dissipation portion 121 protrudes from the second heat-generating element 122 , the projection size of the first heat dissipation portion 121 is ∈ [0.01 mm, 0.03 mm].

[0104] On the first projection, the direction along which the first heat dissipation portion 121 protrudes from the second heat generating element 122 refers to the width direction b of the second heat generating element 122 , that is, the width direction b of the heating bar 1221 .

[0105] It can be understood that the dimension of the first heat dissipation portion 121 in the width direction b of the second heat generating element 122 is a first width H4, and the first width H4∈[0.01mm, 0.03mm]. Specifically, the first width H4 can be 0.01mm, 0.012mm, 0.015mm, 0.018mm, 0.02mm, 0.022mm, 0.025mm, 0.028mm, 0.03mm, etc.

[0106] Such a configuration ensures that the overall size of the heating component 12 is not too large while the first heat dissipation portion 121 can effectively disperse heat, thereby improving the problem of the resistance of the heating structure 10 being affected by the excessive configuration of the first heat dissipation portion 121 .

[0107] In some embodiments, please refer to Figure 2 and Figure 3 The heating structure 10 further includes heat sinks 2 disposed at opposite ends of the heating component 12 along the second direction Y, and the heat sinks 2 on the same side of two adjacent heating components along the second direction Y are spaced apart.

[0108] The heat sink 2 refers to a component having thermal conductivity and used for heat dissipation.

[0109] The heat sink 2 is provided at both opposite ends of the heat generating assembly 12 along the second direction Y, and the heat sinks 2 of two adjacent heat generating components on the same side of the second direction Y are spaced apart, so that the heat sink 2 can effectively dissipate heat.

[0110] Specifically, the heat sink 2 is connected to the connection between the two heat-conducting strips of the second heat-conducting member. The connection between the two heat-conducting strips of each second heat-conducting member is provided with a heat sink 2, the heat sink 2 is extended along the second direction Y, and the heat sinks 2 at each end of the heating component 12 along the second direction Y are spaced apart along the first direction X.

[0111] In some embodiments, the heat sink 2 may be, but is not limited to, a metal structure. Specifically, the heat sink 2 may be made of at least one of metal materials such as iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, and pure titanium.

[0112] In some embodiments, the heat-generating component 12 has a second through hole at the first heat-dissipating portion 121 .

[0113] The heating component 12 at the first heat dissipation part 121 refers to the vicinity of the first heat dissipation part 121 of the heating component 12. The second through hole can be provided on the second heating element 122 of the heating component 12, can also be provided on the first heat dissipation part 121 of the heating component 12, and can also be provided on both the second heating element 122 and the first heat dissipation part 121.

[0114] The second through hole is provided at the first heat dissipation portion 121 of the heat generating component 12 so that the heat generating component 12 can effectively dissipate heat through the second through hole, thereby improving the problem of local heat concentration of the heat generating structure 10 .

[0115] In addition, the provision of the second through hole also facilitates the atomization of the atomized liquid on the oil-conducting cotton 20 on one side of the heating structure 10 to flow to the other side of the heating structure 10. In this way, the liquid supply speed and liquid supply efficiency of the atomization core can be improved.

[0116] Specifically, the second through hole passes through the heat generating component 12 along the third direction Z.

[0117] It should be noted that the first heat dissipation portion 121 is provided on the second heating element 122 so that the resistance of the heating component 12 is within the required range. The second through hole is provided on the heating component 12 so that the resistance of the heating component 12 is within the required range.

[0118] In some embodiments, please refer to Figures 2 to 4 , and in combination with other drawings. The second heat dissipation portion includes a third through hole 102 disposed on the first heat generating element 11 .

[0119] The second heat dissipation portion includes a third through hole 102 arranged on the first heating element 11, so that the first heating element 11 can achieve effective heat dissipation through the third through hole 102, which can improve the problem of local heat concentration of the heating structure 10, help to improve the temperature uniformity of the heating structure 10, and extend the service life of the heating structure 10.

[0120] In addition, the third through hole 102 is also provided to facilitate the atomization of the atomized liquid on the oil-conducting cotton 20 on one side of the heating structure 10 to flow to the other side of the heating structure 10. In this way, the liquid supply speed and liquid supply efficiency of the atomizer core can be improved.

[0121] Specifically, the third through hole 102 passes through the first heat generating element 11 along the third direction Z.

[0122] In some embodiments, please refer to Figure 2 and Figure 3 , and in combination with other drawings. A third through hole 102 is provided on the first heating element 11 between any two adjacent heating components 12 .

[0123] It should be noted that the heat of the first heating element 11 between two adjacent heating components 12 is generally higher. By providing the third through hole 102 on the first heating element 11 between any two adjacent heating components 12, it is helpful to achieve effective heat dissipation of the first heating element 11 between any two adjacent heating components 12, thereby helping to improve the problem of local heat concentration of the heating structure 10.

[0124] In some embodiments, please refer to Figure 2 and Figure 3 , and in combination with other drawings. The first heating element 11 located at two opposite ends of the heating body 1 along the first direction X may also be provided with a third through hole 102 .

[0125] In some embodiments, please refer to Figures 2 to 4 , and in combination with other drawings, the first heat dissipation portion 121 is rectangular, trapezoidal, parallelogram, circular, elliptical or irregular.

[0126] It can be understood that, on the first projection, the projection of the first heat dissipation portion 121 is rectangular, trapezoidal, parallelogram, circular, elliptical or irregular.

[0127] Such configuration allows the first heat dissipation portion 121 to be flexibly formed.

[0128] In some embodiments, please refer to Figure 2 and Figure 3 , and in combination with other drawings. The second heat dissipation portion is rectangular, trapezoidal, parallelogram, circular, elliptical or irregular.

[0129] It can be understood that on the first projection, the projection of the second heat dissipation portion is rectangular, trapezoidal, parallelogram, circular, elliptical or irregular. Specifically, on the first projection, the projection outline of the third through hole 102 is rectangular, trapezoidal, parallelogram, circular, elliptical or irregular.

[0130] Such an arrangement makes the second heat dissipation portion very flexible.

[0131] In some embodiments, please refer to Figures 1 to 3 The heating structure 10 further includes two first conductive members 3 , which are respectively connected to the first heating members 11 at opposite ends of the heating body 1 along the first direction X.

[0132] The first conductive member 3 refers to a component having conductive properties.

[0133] It can be understood that one of the first conductive members 3 is connected to the first heating member 11 at one end of the heating body 1 along the first direction X, and the other first conductive member 3 is connected to the first heating member 11 at the other end of the heating body 1 along the first direction X. Based on this, the heating body 1 and the two first conductive members 3 are conductive.

[0134] With such arrangement, the current can sequentially pass through one of the first conductive members 3 , the heating body 1 and the other first conductive member 3 .

[0135] In some embodiments, the first conductive member 3 may be a metal structure. Specifically, the first conductive member 3 may be made of at least one of metal materials such as iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, and pure titanium.

[0136] In some embodiments, please refer to Figures 1 to 3 The heating structure 10 further includes a second conductive member 4 , which is connected to the first conductive member 3 and spaced apart from the heating body 1 along the second direction Y.

[0137] The second conductive member 4 refers to a component having conductive properties.

[0138] The second conductive member 4 is connected to the first conductive member 3 so that the first conductive member 3 and the second conductive member 4 are electrically connected.

[0139] Such an arrangement enables the current to sequentially pass through one of the second conductive members 4 , one of the first conductive members 3 , the heating body 1 , another first conductive member 3 , and another second conductive member 4 .

[0140] In some embodiments, the second conductive member 4 may be a metal structure. Specifically, the second conductive member 4 may be made of at least one of metal materials such as iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, and pure titanium.

[0141] In some embodiments, the heat generating body 1 may be an integrally formed structure.

[0142] In some embodiments, the heat generating body 1 may be a sheet-like structure, and the thickness direction of the heat generating body 1 is parallel to the third direction Z.

[0143] In some embodiments, the whole formed by connecting the heat-generating body 1 , the heat-dissipating element 2 , the first conductive element 3 , and the second conductive element 4 may be an integrally formed structure.

[0144] In some embodiments, the whole formed by the heating body 1, the heat sink 2, the first conductive member 3 and the second conductive member 4 can be a sheet-like structure, and the thickness direction of the whole formed by the heating body 1, the heat sink 2, the first conductive member 3 and the second conductive member 4 is parallel to the third direction Z.

[0145] In some embodiments, please refer to Figures 1 to 3 , and in combination with other drawings. The first conductive member 3 is provided with a fourth through hole 103 .

[0146] By providing the fourth through hole 103 on the first conductive member 3, the air pressure on the two opposite sides of the heating structure 10 along the through direction of the fourth through hole 103 can be quickly balanced, and the atomized liquid on the oil-conducting cotton 20 on one side of the heating structure 10 is convenient to be atomized and flow to the other side of the heating structure 10. This helps to improve the liquid supply speed and liquid supply efficiency of the atomizer core.

[0147] Specifically, the atomizer device where the atomizer core is located generally needs to be tested for a negative pressure environment before use. After completing the negative pressure environment test and restoring the normal pressure environment, the air pressure of the atomizer device at the atomizer core is unbalanced. Specifically, in the through direction of the first through hole 101, the air pressure on the opposite sides of the heating structure 10 is relatively different, which makes the atomized liquid on the oil-conducting cotton 20 flow back to the heating structure 10, and the air pressure of the atomizer device at the atomizer core is difficult to quickly restore balance. In this way, the atomized liquid on the oil-conducting cotton 20 is difficult to guide to the heating structure 10 due to the imbalance of air pressure, which makes the liquid supply speed of the atomizer core slow, the liquid supply efficiency is low, and the problem of burning is easy to occur. By setting the fourth through hole 103 on the first conductive member 3, the gas on the opposite sides of the heating structure 10 can be circulated through the fourth through hole 103, thereby helping to balance the air pressure on the opposite sides of the heating structure 10, so as to improve the liquid supply efficiency of the atomizer core, and help to improve the problem of burning the atomizer core.

[0148] Specifically, the fourth through hole 103 passes through the first conductive member 3 along the third direction Z.

[0149] In some embodiments, see Figure 1 , and in combination with other drawings. The heating structure 10 further includes two electrodes 6 , and the two electrodes 6 are connected to the second conductive members 4 on the two first conductive members 3 respectively.

[0150] With such arrangement, a power source can be connected through the two electrodes 6 so that the heating body 1 of the heating structure 10 can be energized through the two electrodes 6, so that the heating body 1 is energized and heated to atomize the atomized liquid.

[0151] In some embodiments, please refer to Figures 1 to 3 The two first conductive members 3 are respectively arranged at opposite ends of the heating body 1 along the first direction X, the second conductive member 4 is bent relative to the first conductive member 3, and the second conductive members 4 on the two first conductive members 3 are respectively arranged at opposite ends of the heating body 1 along the second direction Y.

[0152] In some embodiments, please refer to Figures 1 to 3, and combined with other drawings. The heating structure 10 also includes a plurality of connecting bars 5. Specifically, one end of the two connecting bars 5 is connected to the first heating element 11 at one end of the heating body 1 along the first direction X, and the other end is connected to the first conductive element 3 at intervals, so that the first conductive element 3, the first heating element 11 and the two connecting bars 5 are surrounded to form a fifth through hole 104.

[0153] The fifth through hole 104 penetrates the heating structure 10 along the third direction Z.

[0154] The connecting bar 5 refers to a component having conductive properties.

[0155] In some embodiments, the connecting bar 5 may be a metal structure, and the connecting bar 5 may be made of at least one of metal materials such as iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, and pure titanium.

[0156] The heating body 1, the heat sink 2, the connecting strip 5, the first conductive member 3 and the second conductive member 4 can be integrally formed.

[0157] It should be noted that the first through hole 101, the fifth through hole 104, and the gap formed by the two adjacent heat sinks 2 all help to balance the air pressure on the opposite sides of the heating structure 10, and help to guide the atomized liquid of the oil-guiding cotton 20 to flow onto the heating structure 10. This helps to improve the liquid supply efficiency of the atomizer core and helps to improve the problem of the atomizer core burning.

[0158] See also Figure 1 , and combined with other drawings. The atomizer core provided in the embodiment of the present application includes a heating structure 10 and an oil-conducting cotton 20. The oil-conducting cotton 20 is arranged on one side of the heating structure 10 along the through direction of the first through hole 101. Among them, the heating structure 10 in this embodiment is the same as the heating structure 10 in the above embodiments. Please refer to the relevant description of the heating structure 10 in the above embodiments for details, which will not be repeated here.

[0159] Specifically, the oil-conducting cotton 20 is arranged on one side of the heating structure 10 along the third direction Z, and the oil-conducting cotton 20 can cover the heating body 1, the heat sink 2, the connecting strip 5, the first conductive member 3 and the second conductive member 4 of the heating structure 10, so that the atomized liquid on the oil-conducting cotton 20 can be guided to flow to the heating structure 10 for heating and atomization of the heating structure 10.

[0160] The atomizer core provided in the embodiment of the present application, by adopting the heating structure 10 involved in the above embodiments, helps to improve the problem of local heat concentration in the atomizer core, improves the temperature uniformity of the atomizer core, thereby helping to reduce the risk of burning the atomizer core and helping to extend the service life of the atomizer core.

[0161] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
