A section is arbitrarily taken on the heating element 1 along the extension direction D, the section area of at least one section on the heating body 11 is smaller than that of any section on the electric contact part 14, according to a resistance calculation formula R ═ rho L/S, wherein R is the resistance value of the heating element 1, rho is the resistance coefficient of the material of the heating element 1, and S is the section area of the section taken on the heating element 1 along the extension direction D, when the section area on the heating body 11 is smaller, the resistance on the heating body 11 is increased, and when current passes through the heating element 1, the heating power on the heating body 11 is larger than that of the electric contact part 13, so that the heating efficiency of the heating element 1 is improved.
The size of the heating element in the electronic cigarette is small, the processing size precision can directly influence the resistance distribution arrangement of the heating element 1, particularly the heating body 11, and on one hand, the size precision of the heating body 11 determines the overall heating effect of the heating element 1; on the other hand, the dimensional accuracy of the heating body 11 determines the uniformity of the resistance distribution on the heating body 11, and improving the dimensional accuracy of the heating body 11 can prevent the heating body 11 from breaking and failing due to uneven temperature distribution of the heating body 11, so as to improve the overall structural strength of the heating element 1, and therefore the dimensional accuracy of the outer contour of the heating body 11 needs to be reduced to make the resistance distribution of the heating element 1 meet the design requirements, and improve the overall strength of the heating element 1.
The heating element 1 is cut by adopting traditional machining modes such as stamping, cutting and the like, and a heat affected zone at the position of a cut on the heating element 1 is larger in the machining process, so that the performance of the heating element 1 is affected; burrs are generated at the cut positions of the heat generating member 1 after the machining, and the heat generating member 1 is deformed by a large amount along with the release of the residual stress.
The laser cutting utilizes a high-power-density laser beam to irradiate the plate material of the heating part 1, so that the material at the cut position on the plate material of the heating part 1 is rapidly heated and melted, vaporized and ablated or reaches a burning point, meanwhile, the melted material is blown off by high-speed airflow coaxial with the beam, a hole is formed at the cut position, and the hole continuously forms a cutting seam with a narrow width along with the movement of the beam relative to the plate material of the heating part 1, thereby completing the cutting of the plate material of the heating part 1 and obtaining the heating part 1 with a required shape.

In the present embodiment, the notch 17 is a through groove, and the notch 17 penetrates the heat generating body 11. It is understood that in other embodiments, the notch 17 is a blind notch, and the notch 17 does not penetrate the heat generating body 11.
In one embodiment, the lattice microstructure is formed on the surface of the heating element 1 by using laser, and the surface of the heating element 1 is hydrophobic or hydrophobic and oleophobic, so that aerosol-forming matrix or sediment is prevented from being adhered to the surface of the heating element 1, and the anti-condensation capability of the surface of the heating element 1 to smoke oil and the anti-charring capability of the sediment are improved.
The heating element 1 is typically made of an electrically conductive, electrically resistive material, such as stainless steel or a copper alloy. Generally, the electrically conductive resistance material has a high surface energy, when the aerosol-forming substrate or deposit contacts the surface of the heating member 1, the aerosol-forming substrate or deposit has a tendency to spread and expand the surface area, the expanded surface area of the aerosol-forming substrate or deposit increases the surface energy, for the surface of the high-surface-energy heating member 1, the expanded surface area of the aerosol-forming substrate or deposit decreases the surface area of the heating member 1, the surface energy of the heating member 1 decreases, during the spreading of the aerosol-forming substrate or deposit on the surface of the heating member 1, the surface of the heating member 1 can be provided with the aerosol-forming substrate or deposit, therefore, the surface of the heating member 1 is hydrophilic, and as part of the aerosol-forming substrate or deposit material on the surface of the heating member 1 volatilizes into the air, the aerosol-forming substrate or deposit remaining on the surface of the heating member 1 adheres to the surface of the heating, so that the heating member 1 generates heat unevenly, thereby reducing the service life of the heating member 1.
At present, two approaches for obtaining hydrophobicity or hydrophobicity and oleophobicity on the surface of the heating element 1 mainly comprise two approaches, wherein one approach is to construct a micro/nano coarse structure on the surface of a low-surface-energy material; the other method is to prepare a rough surface structure on the surface of a high-surface-energy material and then modify a low-surface-energy material on the rough surface. For the surface of the heating element 1 with high surface energy, the method is suitable for firstly preparing a rough surface structure and then modifying a low-surface-energy material on the rough surface to ensure that the surface of the heating element 1 obtains hydrophobicity or oleophobicity. In this embodiment, a lattice microstructure is formed on the surface of the heat generating member by using laser, and then a low surface energy material is modified on the lattice microstructure. Specifically, referring to fig. 3 and 4, a pit 21 is formed on the surface of the heat generating member 1 by laser irradiation, a material in the pit 21 is melted and stacked around the pit 21 to form a deposit 23, the spot diameter of the laser is the same as the spot diameter of the pit 21, the spot diameter of the laser is d, the lattice interval is p, the lattice interval p is larger than the spot diameter d, the lattice is arranged in an array form, so that the deposit 23 is arranged in the array form, the aerosol forming substrate or the deposit is gathered and suspended on the surface of the heat generating member 1, and the surface of the heat generating member 1 is hydrophobic or oleophobic. It is understood that the laser processing causes the surface of the heat generating member 1 to form a stack arranged in an array, so that the surface of the heat generating member 1 exhibits hydrophobicity or oleophobicity. Preferably, referring to fig. 4, the material in any two adjacent pits 21 is melted and stacked together to form a stack 23, and the heat generating member 1 exhibits better water repellency or water and oil repellency. Referring to fig. 5, as the dot pitch p increases, aerosol-forming substrate or deposits easily enter the grooves 25 between adjacent deposits 23, and the surface of the heat generating member 1 becomes hydrophilic. When the dot matrix interval p is smaller than the diameter d of the light spot, the adjacent point pits 21 are partially overlapped, the melted materials in the point pits 21 are piled up and solidified, the surface of the heating element 1 is more accumulated 23, the surface roughness is increased, the micro/nano rough structure requirement is not met, and the surface of the heating element 1 is hydrophilic.
In the embodiment, the outer contours of the heat generating body 11 and the connecting portion 13 and the inner contour of the notch 17 are formed by laser cutting, so that the dimensional accuracy of the heat generating member 1 is high, the width and the deformation of the heat affected zone at the position of the notch are small, and the production efficiency of the heat generating member 1 is high. Further, a lattice microstructure is formed on the surface of the heating element 1 by utilizing laser, the surface of the heating element 1 is hydrophobic or hydrophobic and oleophobic, so that aerosol forming matrixes or sediments are prevented from being adhered to the surface of the heating element 1, and the anti-condensation capacity of the surface of the heating element 1 on the smoke and the anti-carbonization capacity of the sediment are improved.
