[0036] Please refer to Figure 1 and Figure 2 The heating structure 20 provided by the embodiments of the present application will be described. The heating structure 20 is applied to an atomizing core.

[0037] The heating structure 20 includes a first wire 30, a plurality of heating meshes 21, and a plurality of second wires 40. The first wire 30 is arranged to extend along a preset direction a. The plurality of heating meshes 21 are arranged to be staggered on both sides of the first wire 30 along the preset direction a, and one end of each heating mesh 21 is electrically connected to the first wire 30, respectively. The second wires 40 are arranged to extend along the preset direction a, and the plurality of second wires 40 are arranged to correspond to the plurality of heating meshes 21 one by one. Wherein, one end of each heating mesh 21 away from the first wire 30 is electrically connected to the corresponding second wire 40.

[0038] Optionally, the first wire 30 is a positive electrode wire, and the second wire 40 is a negative electrode wire. Alternatively, the first wire 30 is a negative electrode wire, and the second wire 40 is a positive electrode wire.

[0039] Compared with the prior art, the heating structure 20 provided by the present application increases the spatial distance between the heating meshes 21 by arranging the plurality of heating meshes 21 to be staggered on both sides of the first wire 30 along the preset direction a, which is conducive to reducing the influence of heat radiation between the heating meshes 21, thereby effectively avoiding the excessive concentration of heat in the atomizing core, which leads to the temperature of the gas outlet end 111 of the atomizing core being too high, and thus is conducive to improving the user experience. In addition, by electrically connecting the first wire 30 to each heating mesh 21, the plurality of heating meshes 21 share one first wire 30, which is conducive to reducing the number of first wires 30, simplifying the structure, and making the performance of the heating structure 20 more stable and reliable. By adopting a plurality of second wires 40 to be electrically connected to the plurality of heating meshes 21 one by one, the on-off of each second wire 40 can be controlled individually, thereby realizing the independent control of the heating working condition of each heating mesh 21. In this way, the heating power of the heating structure 20 can be adjusted according to the demand. For example, when the temperature of the gas outlet end 111 is too high, a part of the heating meshes 21 can be powered to heat, and the other part of the heating meshes 21 can be powered off to reduce the heating power of the entire heating structure 20, thereby reducing the temperature of the gas outlet end 111.

[0040] Specifically, the existing single-core double-fogging atomizing core with left and right distributed double-mesh heating structure has double meshes arranged side by side, that is, the double meshes are arranged at the same height, and the double meshes are relatively close to each other, which causes the double meshes to be greatly affected by thermal radiation between each other, easily leading to heat concentration in the atomizing core, and further causing the temperature of the air outlet end of the atomizing core to be too high. The heating structure 20 of the embodiment of the present application is arranged on both sides of the first wire 30 along the preset direction a by staggering a plurality of heating meshes 21, so as to increase the spatial distance between the heating meshes 21, which is conducive to reducing the thermal radiation effect between the heating meshes 21, thereby effectively avoiding the heat in the atomizing core from being too concentrated, and further conducive to reducing the temperature of the air outlet end 111 of the atomizing core.

[0041] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The number of heating meshes 21 is two, and the two heating meshes 21 are arranged in sequence along the preset direction a, and the two heating meshes 21 are respectively located on both sides of the first wire 30.

[0042] By setting the number of heating meshes 21 to two, the structure is simple and easy to manufacture. By arranging the two heating meshes 21 in sequence along the preset direction a, the spatial distance between the two heating meshes 21 is increased, which is conducive to reducing the thermal radiation effect between the two heating meshes 21. Moreover, the two heating meshes 21 are respectively located on both sides of the first wire 30, which is conducive to realizing the electrical connection between the two heating meshes 21 and the first wire 30.

[0043] Optionally, the two heating meshes 21 are arranged adjacent to each other along the preset direction a. Specifically, there is no overlapping part between the two heating meshes 21 along the preset direction a, and the distance between the two heating meshes 21 is equal to zero.

[0044] By arranging the two heating meshes 21 adjacent to each other along the preset direction a, the two heating meshes 21 do not overlap each other along the preset direction a, so as to increase the spatial distance between the two heating meshes 21, thereby being conducive to reducing the thermal radiation effect between the two heating meshes 21.

[0045] Optionally, the two heating meshes 21 are arranged at intervals along the preset direction a. Specifically, the distance between the two heating meshes 21 along the preset direction a is greater than zero.

[0046] By arranging the two heating meshes 21 at intervals along the preset direction a, the spatial distance between the two heating meshes 21 is further increased, thereby being conducive to further reducing the thermal radiation effect between the two heating meshes 21, so that the heat in the atomizing core is more evenly distributed.

[0047] In some embodiments of the present application, referring to FIG. 1 and FIG. 2, the two heating meshes 21 are staggered around the circumference of the preset direction a. Among them, the two heating meshes 21 staggered around the circumference of the preset direction a means that there is no overlapping part between the two heating meshes 21 around the circumference of the preset direction a, for example, the two heating meshes 21 are arranged adjacent to or spaced apart around the circumference of the preset direction a.

[0048] By staggering the two heating meshes 21 around the circumference of the preset direction a, it is beneficial to further increase the spatial distance between the two heating meshes 21, thereby further reducing the heat radiation influence between the two heating meshes 21, thereby effectively avoiding the excessive concentration of heat inside the atomization core.

[0049] Optionally, the transverse cross section of the heating mesh 21 is arc-shaped, U-shaped or V-shaped, etc. Among them, the transverse cross section of the heating mesh 21 refers to the cross section obtained by taking the heating mesh 21 with a plane perpendicular to the preset direction a.

[0050] The number of second wires 40 is the same as the number of heating meshes 21. For example, when the number of heating meshes 21 is two, the number of second wires 40 is also two, and the two second wires 40 are respectively electrically connected with the two heating meshes 21.

[0051] In some embodiments of the present application, in order to avoid the mutual influence of the current between the first wire 30 and the second wire 40, and between the second wire 40 and the second wire 40, an insulating layer such as an insulating skin can be arranged outside the first wire 30 and the second wire 40.

[0055] Compared with the prior art, the atomizing core provided in the application adopts the heating structure 20. The heating structure 20 is obtained by arranging a plurality of heating meshes 21 on both sides of the first wire 30 in the preset direction a. Thus, the space distance between the heating meshes 21 is increased, which is conducive to reducing the heat radiation influence between the heating meshes 21, thereby effectively avoiding the excessive concentration of heat in the atomizing core, the excessively high temperature of the air outlet end 111 of the atomizing core, and further improving the user experience.

[0056] The shape of the atomizing tube 10 is set according to the shape of the heating structure 20. Specifically, the transverse cross section of the atomizing tube 10 is adapted to the transverse cross section of the heating structure 20.

The transverse cross section of the heating structure 20 refers to the cross section obtained by cutting the heating structure 20 in a plane perpendicular to the preset direction a.

[0057] Optionally, the transverse cross section of the heating structure 20 can be, but is not limited to, circular, waist-shaped, elliptical, square or triangular, and the like. Thus, the transverse cross section of the atomizing tube 10 can also be waist-shaped, elliptical, circular, square or triangular, and the like, which is adapted to the heating structure 20.

[0058] In some embodiments of the application, referring to FIGS. 1 and 2, the transverse cross section of the atomizing tube 10 is circular. Each heating mesh 21 is curved around the circumferential direction of the preset direction a and is attached to the inner wall of the atomizing tube 10. For example, when the number of heating meshes 21 is two, the two heating meshes 21 are identical in size. The transverse cross section of each heating mesh 21 is semicircular, and the radius of the heating mesh 21 is equal to the inner diameter of the atomizing tube 10.

[0059] When the transverse cross section of the atomizing tube 10 is circular, the heating mesh 21 is curved around the circumferential direction of the preset direction a and is attached to the inner wall of the atomizing tube 10. This is conducive to increasing the attachment area of the heating mesh 21 and the atomizing tube 10, thereby improving the atomization efficiency and the stability of the heating mesh 21 fixed and accommodated in the atomizing tube 10.

[0060] In some embodiments of the application, referring to FIGS. 1 and 2, the transverse cross section of the atomizing tube 10 is circular.

The transverse cross section of each heating mesh 21 is semicircular, and the radius of the heating mesh 21 is equal to the inner diameter of the atomizing tube 10.

The guide cotton 12 is annular, and each heating mesh 21 is attached to the inner wall of the guide cotton 12.

[0061] The tube body 11 is used to fix and accommodate the guide cotton 12 and the heating structure 20. The shape of the tube body 11 is adapted to the heating structure 20. When the guide cotton 12 is accommodated in the tube body 11, the shape of the guide cotton 12 is adapted to the tube body 11. Thus, when the heating mesh 21 is attached to the inner wall of the guide cotton 12, the position of each heating mesh 21 is fixed by the tube body 11.​

[0062] In some embodiments of the present application, referring to Figure 3 and Figure 4 , the side wall of the tube body 11 is provided with an oil guide groove 112, and the oil guide cotton 12 includes a main body part 121 in a ring shape and an oil guide part 122 extending radially from the outer wall of the main body part 121, the main body part 121 is accommodated in the tube body 11, and the end of the oil guide part 122 away from the main body part 121 extends out through the oil guide groove 112.
