In the design, the value range of the aperture of the through hole is limited, and specifically, the aperture b of the through hole satisfies that b is more than or equal to 0.2mm and less than or equal to 0.7 mm. It can be understood that if the diameter of the through-hole is too small, the flow of the aerosol-generating substrate is not facilitated, and the atomization amount of the aerosol-generating device is reduced. If the aperture of the through hole is too large, the structural strength of the supporting tube is reduced, and the service life of the heating body is further reduced. The aperture of the through hole is limited between 0.2mm and 0.7mm, so that the atomizing amount of the aerosol generating device can be ensured, and the service life of the heating body can be prolonged.

That is, the conducting layer 121 is a cotton layer, that is, the heating element 100 is a cotton core heating element, so that the atomizing amount of the aerosol generating device can be increased while the atomizing layer 120 is ensured to have good integrity and consistency.
Further, by including 8 to 64 strands of cotton yarn or cotton yarn, the conductive layer 121 formed by knitting can be ensured to have a set thickness and flow properties.
In practical application, the yarns can be single-strand yarns or formed by combining 2-8 secondary yarns, and can be specifically arranged according to actual needs.
On the basis of the above embodiment, further, the yarns are single-strand primary yarns; or the yarn comprises from 2 to 8 secondary yarns.
In this embodiment, it is defined that the yarns may be single-strand primary yarns, i.e., 8 to 64 strands of primary yarns are woven with the heat generating wire by a weaving machine to form the atomizing layer 120, so that the conductive layer 121 and the heat generating layer 122 are formed as an integral woven structure. The yarn may be formed by combining 2 to 8 secondary yarns, and the combined 8 to 64 secondary yarns and the heating wire may be woven by a weaving machine to form the atomizing layer 120, so that the conductive layer 121 and the heating layer 122 are formed into an integral woven structure. Thereby improving the atomization amount of the aerosol generating device while ensuring the good integrity and consistency of the atomization layer 120.
In practical application, the yarn material can be twisted yarn or untwisted yarn made of filaments or short filaments, and can be specifically set according to actual requirements.
In a specific embodiment, further, the diameter D1 of the yarn satisfies 0.05mm < D1 < 0.2 mm.
In this embodiment, the range of the yarn diameter D1 is defined. I.e., the range of values defining the diameter of each primary yarn or each combined secondary yarn. It can be understood that if the diameter of the yarn is too small, the structural strength of the conductive layer 121 formed by weaving becomes low, and the service life of the heating element 100 is reduced. If the diameter of the yarn is too large, the conductive layer 121 formed by weaving is likely to be too thick, which is disadvantageous for the flow of the aerosol-generating substrate and affects the atomization amount of the aerosol-generating device. By limiting the diameter of the yarn to 0.05mm to 0.2mm, the atomization amount of the aerosol generating device can be increased while ensuring a certain structural strength of the conductive layer 121.
In another specific embodiment, further, the fineness S1 of the yarn satisfies 10 counts S1 60 counts.
In this embodiment, it can be understood that the larger the fineness of the yarn is, the smaller the yarn diameter is, and by further limiting the value range of the fineness of the yarn, the atomizing amount of the aerosol generating device can be increased while the conductive layer 121 can be further ensured to have a certain structural strength.
On the basis of the above embodiment, further, the heating wire includes 2 to 64 strands of primary heating wires.
In this embodiment, it is defined that the heating wire includes 2 strands to 64 strands of primary heating wires, that is, 2 strands to 64 strands of primary heating wires and cotton or cotton yarn are woven to form the atomizing layer 120, so that the conducting layer 121 and the heating layer 122 are formed into an integral woven structure. Compared with the assembly of the heating body 100 by manual assembly in the related art, the assembly efficiency can be obviously improved, the product consistency of the heating body 100 can be improved, the uniform distance between the atomizing layer 120 and the support tube 110 can be ensured, the leakage of the product can be prevented, and the taste of different aerosol generating devices can be well consistent.
In practical application, the heating wire can be made of iron-chromium-aluminum, nickel-chromium, titanium wire or nickel wire, and the heating wire can be specifically set according to actual needs.
In a specific embodiment, further, the diameter D2 of the primary heating wire satisfies 0.01mm ≦ D2 ≦ 0.2 mm; and/or the fineness S2 of the primary heating wire satisfies that 10 branches are less than or equal to S2 is less than or equal to 60 branches.
In the embodiment, the value range of the diameter of the primary heating wire is limited, and particularly, the diameter D2 of the primary heating wire meets the requirement that D2 is more than or equal to 0.2mm and is more than or equal to 0.01 mm. The heating wire is too thin and easy to break, which is not beneficial to spinning; the heating wire is too thick and has strong rigidity, which is not favorable for being woven with cotton yarn to form a compact structure. By limiting the diameter of the primary heating wire to between 0.01mm and 0.2mm, effective atomization of the aerosol generating device, and generation of aerosol, can be ensured.
The fineness of the primary heating wire is limited between 10 and 60, so that the effective atomization of the aerosol generating device and the generation of the aerosol can be further ensured.
Example three:
as shown in fig. 5, on the basis of the above embodiment, further, the support tube 110 includes a body 111 and a plurality of through holes 112, wherein the body 111 is provided with a conducting cavity, the plurality of through holes 112 are provided in the body 111, and the plurality of through holes 112 are communicated with the conducting cavity and the atomizing layer 120.
In this embodiment, the support tube 110 is defined to include a body 111 and a plurality of through holes 112, and specifically, the body 111 is provided with a conducting cavity, it can be understood that the aerosol generating substrate can pass into the conducting cavity and flow to the conducting layer 121 through the plurality of through holes 112 on the body 111, and the heating wire of the heating layer 122 heats and atomizes the aerosol generating substrate flowing to the conducting layer 121 to generate aerosol.
In practical applications, the material of the support tube 110 includes one of a metal material, a ceramic material, glass or an engineering plastic, so as to ensure the structural strength of the support tube 110, and further, to provide an effective support for the atomizing layer 120.
Specifically, the material of the support tube 110 may be stainless steel, dense ceramic, or porous ceramic, and may be specifically set according to actual needs.
It should be noted that the through hole 112 may be a circular hole or an elliptical hole, and may be specifically configured according to actual needs. And the number of through holes 112 may also be set according to actual needs or the size of the particular aerosol generating device.
On the basis of the above embodiment, further, the atomizing layer 120 includes a plurality of capillary holes; the aperture of the through-hole 112 is smaller than the inner diameter of the body 111 and larger than the diameter of the capillary.
In this embodiment, the aerosolizing layer 120 is defined to comprise a plurality of capillary apertures, it being understood that the plurality of capillary apertures are in communication with the through-holes 112, the through-holes 112 having a smaller pore size than the inner diameter of the body 111, and the through-holes 112 having a larger pore size than the diameter of the capillary apertures, thereby enabling an efficient circulation of the aerosol-generating substrate and hence an aerosolization volume of the aerosol-generating device.
In a specific embodiment, further, the inner diameter d of the body 111 satisfies 0.5mm ≦ d ≦ 3.0 mm; and/or the thickness a of the body 111 satisfies 0.1mm < a < 0.2 mm.
In this embodiment, a value range of the inner diameter of the body 111, that is, a value range of the width of the conduction cavity, is defined. It can be understood that if the inner diameter of the body 111 is too small, i.e. the width of the conducting cavity is too small, the amount of aerosol-generating substrate per unit volume will be smaller, reducing the amount of aerosol generated by the aerosol generating device. If the inner diameter of the body 111 is too large, the volume of the heating element 100 is large, which occupies the inner space of the aerosol generating device, and also causes the volume of the aerosol generating device to be large, which is not favorable for the beauty of the product. By limiting the inner diameter of the body 111 to 0.5mm to 3.0mm, the aesthetic appearance of the product can be improved while ensuring the atomization amount of the aerosol generating device.
In addition, the value range of the thickness of the body 111 is limited, and specifically, the thickness a of the body 111 satisfies that a is more than or equal to 0.1mm and less than or equal to 0.2 mm. Thus, the structural strength of the support pipe 110 can be ensured, and the service life of the heating element 100 can be extended.
In another specific embodiment, further, the aperture b of each through-hole 112 satisfies 0.2mm ≦ b ≦ 0.7 mm.
In this embodiment, the value range of the aperture of the through hole 112 is defined, specifically, the aperture b of the through hole 112 satisfies 0.2mm ≦ b ≦ 0.7 mm. It will be appreciated that too small a diameter of the through-holes 112 will be detrimental to the flow of aerosol-generating substrate and reduce the amount of aerosol produced by the aerosol generating device. If the diameter of the through hole 112 is too large, the structural strength of the support tube 110 is reduced, and the service life of the heating element 100 is reduced. By limiting the diameter of the through hole 112 to 0.2mm to 0.7mm, the life of the heating element 100 can be prolonged while ensuring the atomization amount of the aerosol-generating apparatus.

Further, it can be understood that the integral structure also facilitates mass production, and thus can effectively improve the assembly efficiency of the heat-generating body 100, and further reduce the production cost of the heat-generating body 100 and the aerosol-generating device 200 having the heat-generating body 100.
Specifically, in the related art, when the heating element 100 is produced, the cotton core forming process and the heating wire forming process are separately performed, and after the cotton core and the heating wire are produced, the heating wire is wound around the cotton core or the cotton core wraps the heating wire to be assembled and formed by a manual assembly method. The assembly method causes the problems that the assembly consistency of the heating body 100 product is poor, the distance between the heating wires is not controllable, the distance between the cotton core and the supporting tube 110 is not uniform, and the like, and further causes the problems of liquid leakage and the like of the product of the aerosol generating device. Moreover, the efficiency of manual assembly is low.
Through setting up layer 121 and the layer 122 that generates heat into a body structure that will conduct, that is to say, the forming process who will conduct layer 121 and generate heat layer 122 goes on in step to compare in the equipment that utilizes manual assembly to carry out heat-generating body 100 among the correlation technique, can be when showing improvement assembly efficiency, improve the uniformity of heat-generating body 100 product, it is even to ensure the interval between atomizing layer 120 and the stay tube 110, prevent the product weeping, and can make different aerosol generating device 200's taste have fine uniformity.
