[0033] Example 1

[0034] like Figure 1-2 As shown, an embodiment of the utility model provides a heating component, which includes a heating assembly 1, an electromagnetic coil 5, an insertion tube 3 for inserting a columnar aerosol product 4, and a magnetic conductor 2. The heating assembly 1 includes at least two heating elements 11 arranged in the insertion tube 3 and arranged sequentially in the axial direction of the insertion tube 3. The heating element 11 is made of metal material, such as iron, and two adjacent heating elements 11 are arranged at intervals. The outer periphery of the insertion tube 3 is provided with at least two magnetic conductors 2 corresponding to each of the heating elements 11, and each of the magnetic conductors 2 is provided with the electromagnetic coil 5; wherein, in the insertion direction of the columnar aerosol product 4, the cross-sectional areas of at least two of the heating elements 11 decrease sequentially.

[0035] In this embodiment, at least two or more identical magnetic conductors 2, at least two heating elements 11 of different cross-sectional areas of the heating assembly 1, and at least two identical electromagnetic coils 5 cooperate with the insertion tube 3 to form a heating assembly, and the cross-section of the heating element 11 is perpendicular to the insertion direction of the columnar aerosol product 4. Under the same conditions, the heating element 11 with a smaller cross-sectional area has a faster heating speed and a higher heating temperature. Figure 1As shown, under working conditions, the heating element 11 of the lower section of the heating assembly 1 is first heated to reach the atomization temperature of the columnar aerosol product 4. Based on the principle of thermal convection, the hot air flow generated by the lower section of the heating assembly 1 will be transferred to the upper section of the columnar aerosol product 4. When the upper section of the columnar aerosol product 4 is also heated, the hot air generated by the lower section of the columnar aerosol product 4 will be heated again in the upper section of the columnar aerosol product 4. Therefore, when the heating temperature of the upper end of the columnar aerosol product 4 is lower than that of the lower end of the columnar aerosol product 4, the air inside the columnar aerosol product 4 can be heated to atomize the columnar aerosol product 4, so that the air temperature inside the columnar aerosol product 4 can evenly heat the columnar aerosol product 4. Compared with the method of using a single heating element in the prior art, the heating component of the utility model has higher heating efficiency, more uniform heating heat, and can realize segmented heating, thereby improving the user experience.

[0036] In some embodiments, the heating element 11 is a cylindrical structure, and the axes of at least two of the heating elements 11 are collinear, which is convenient for assembly and manufacturing.

[0037] In some embodiments, the heating assembly 1 also includes a thermal insulation connector 12, and the ends of two adjacent heating elements 11 that are close to each other are respectively plugged into the two ends of the thermal insulation connector 12. The thermal insulation connector 12 fixes at least two heating elements 11 in sequence and isolates the heat conduction between the two adjacent heating elements 11, thereby ensuring the temperature control of different heating elements 11 of the heating assembly 1, making the heating efficiency higher, the heating heat more uniform, and segmented heating possible.

[0038] In some embodiments, the heating assembly 1 also includes a base 13, the insertion tube 3 has a first opening and a second opening, the columnar aerosol product 4 is inserted into the insertion tube 3 from the first opening, and the base 13 is arranged at the second opening. In the insertion direction of the columnar aerosol product 4, the heating element 11 located at the end of at least two of the heating elements 11 is inserted on the base 13, and the heating element 11 of the heating assembly 1 is fixed on the insertion tube 3 through the base 13.

[0039] In some embodiments, the base 13 is made of a high temperature resistant material to prevent the base 13 from being burned. The high temperature resistant material may be glass, ceramic, high temperature resistant plastic, etc.

[0040] In some embodiments, at least two of the electromagnetic coils 5 are constructed by bending a wire. Compared with the combination of two magnetic conductors 2 and two electromagnetic coils 5, at least two electromagnetic coils 5 constructed by bending a wire and connected in series on at least two magnetic conductors 2 will save more costs.

[0041] In some embodiments, at least two of the electromagnetic coils 5 are connected in series in sequence. Compared with the combination of two magnetic conductors 2 and two electromagnetic coils 5, at least two electromagnetic coils 5 are connected in series in sequence in sequence on at least two magnetic conductors 2, which is more cost-effective.

[0042] In some embodiments, the magnetic conductor 2 includes two arc-shaped extensions 21 surrounding the outer periphery of the insert tube 3 and a connecting section 22 arranged between the two arc-shaped extensions 21. The electromagnetic coil 5 is sleeved on the connecting section 22, and the electromagnetic coil 5 is fixed by the connecting section 22. The arc-shaped extension 21 conducts the electromagnetic generated by the electromagnetic coil 5 to the outer periphery of the insert tube 3 to the maximum extent, thereby ensuring the heating efficiency of the heating element 11.

[0043] In some embodiments, the heating component also includes a control board 6 and a battery core 7. The portion between two adjacent electromagnetic coils 5 has a welding point 51. The welding point 51 is welded to the control board 6. The control board 6 is connected to the battery core 7. The welding point 51 makes the welding more secure.
