As shown in conjunction with fig. 5 and 6, in some embodiments, the first wire 1121 includes a seam 1122 that is threaded from the first side a to the second side B opposite the first side a and then back to the first side a, and the seam 1122 allows the first wire 1121 to be stitched to the solid aerosol-forming substrate 111, so that the first wire 1121 better adheres to the solid aerosol-forming substrate 111, and the bond is stable and less prone to loosening. Depending on the stitch length of the first wire 1121, one or other number of stitches 1122 may be provided along the stitch running direction to stitch the first wire 1121 to the solid aerosol-forming substrate 111.

It will be appreciated that in some embodiments, the seam 1122 may include a first section 1122a and a second section 1122B connected in sequence, where the first section 1122a and the second section 1122B are located in the same sewing hole, that is, the seam 1122 may be returned from the original sewing hole to the first side a after the solid aerosol-forming substrate 111 is pierced from the first side a to the second side B, and the seam 1122 may be buried in the solid aerosol-forming substrate 111, so that the solid aerosol-forming substrate 111 may be heated.

Generally, the first wire 1121 is sewn to form the heating body 112 along a predetermined path, and there are a plurality of seams 1122 to ensure stable connection with the solid aerosol-forming substrate 111 and a sufficient heating range. Further, the first wire 1121 further includes a connecting section 1123 located at the first side a and connected between two adjacent seam portions 1122, so that the heating body 112 can be distributed along the first side a for a longer length, and the heating range can be increased. Of course, only one seam 1122 may be provided, and both ends of the heating body 112 may be fixed to the solid aerosol-forming substrate 111 through the electrodes 113.

Alternative materials for the first wire 1121 include: the nickel-based alloy, the stainless steel series alloy, the chromium-containing alloy, the titanium-containing alloy, the tungsten-containing alloy, the molybdenum-containing alloy, the iron-containing alloy, the tin-containing alloy, and other metal materials, or nonmetal conductive materials including carbon fiber wires, graphite fiber wires and the like, can be filaments formed by twisting one or two of superfine conductive metal wires and conductive nonmetal wires, is thinner, can be filaments with diameters of several micrometers to tens of micrometers, and is particularly not limited.

Further, as shown in fig. 9, in other embodiments, the seam 1122 includes a first section 1122a, a third section 1122c, and a second section 1122B connected in sequence, the third section 1122c being located on the second side B, the first section 1122a and the second section 1122B being respectively penetrated by the solid aerosol-forming substrate 111. When the solid aerosol-forming substrate 111 is sewn, the first wire 1121 passes through the solid aerosol-forming substrate 111 from the first side a to the second side B, and passes through the solid aerosol-forming substrate 111 to the first side a after being led out for a certain period along the second side B, and the first wire 1121 is sewn to the solid aerosol-forming substrate 111 in such a cycle, so that both sides of the solid aerosol-forming substrate 111 can be heated, and the solid aerosol-forming substrate 111 is heated and atomized after the heating body 112 heats. Of course, the length of the third section 1122c may be made shorter, and the second side B may be slightly exposed without routing on the second side B, and returned to the first side a along the sewing hole where the first section 1122a is located.

Further, as shown in fig. 11, in order to make the area of heat radiation larger, the heating body 112 includes a plurality of first wires 1121 located on the same side of the solid aerosol-forming substrate 111, preferably, the first wires 1121 may be two or more, each first wire 1121 may be interlaced to form a mesh structure, or each first wire 1121 may be disposed side by side, or may be combined in an interlaced and side by side manner.

Preferably, in some embodiments, the heating body 112 further comprises flexible second wires 1124 sewn on the solid aerosol-forming substrate 111, the first wires 1121 and the second wires 1124 being respectively located on opposite sides of the solid aerosol-forming substrate 111, the first wires 1121 and the second wires 1124 being interwoven with each other to make the bonding of the heating body 112 and the solid aerosol-forming substrate 111 more stable. Generally, the second wire 1124 may be made of an insulating material, so that the side of the heating body 112 where the first wire 1121 is located emits heat, so as to slow down the heating rate, and prevent harmful substances from being generated due to local high temperature in the aerosol forming unit 10. Of course, the second wire 1124 may be made of conductive material, and the first wire 1121 and the second wire 1124 with smaller resistance may be selected to avoid too fast temperature rise and too high temperature.

The sheet-like solid aerosol-forming substrate 111 is a substance such as cloth or paper-like substance produced by extracting a flavor plant fiber from a herb plant, by a paper-making method or the like, which has a certain hygroscopicity and itself generates an aerosol of a herbal-like taste by heating, and can be produced by sufficiently mixing a substance such as propylene glycol, glycerin and an edible essence which has a property of generating smoke into a solvent which can be atomized, the solvent or the like being adsorbed into the herb plant fiber thereof, and when the heat generated by the heating body 112 is a temperature required for atomizing the solvent.
