When the heating net 100 is assembled, the heating net 100 is bent into a columnar structure. The first support portion 30 can enhance the overall strength of the heating net 100 to prevent the outside of the heating net 100 from being wrapped with an oil-conducting material, such as oil-conducting cotton 90. The first heating section 10 and the second heating section 20 are not easily squeezed and deformed, the overall structure is more stable, and the heating is more uniform.

[0045] See also Figures 1 to 3 In one embodiment, the heating net 100 further includes a first connection portion 50 and a second connection portion 60, which are laterally spaced at the two ends of the first heating section 10, respectively.

The first connection part 50 and the second connection part 60 are both in the shape of long sheets. When the heating network 100 is assembled, the first connection part 50 and the second connection part 60 are respectively located at the upper end and the lower end of the columnar structure. The first connection part 50 and the second connection part 60 can enhance the overall strength of the columnar structure, and it is convenient to wrap the oil-conducting cotton 90 without causing squeezing and deformation to the entire columnar structure, so that the overall structure of the heating network 100 is more stable and the heating is more uniform.

[0046] See also Figures 1 to 3In one embodiment, the heating network 100 further includes a first electrode connection terminal 70 and a second electrode connection terminal 80, which are respectively disposed at the first connection portion 50 and the second connection portion 60, and the first electrode connection terminal 70 and the second electrode connection terminal 80 are vertically arranged.

The first electrode connection end 70 and the second electrode connection end 80 can facilitate the welding of the positive wire and the negative wire. In addition, since the first electrode connection end 70 and the second electrode connection end 80 and the positive wire and the negative wire are all arranged vertically, parallel to the arrangement direction of the first heating section 10 and the second heating section 20, it can prevent the first heating section 10 and the second heating section 20 from being subjected to lateral tension during the assembly of the positive wire and the negative wire, thereby making the overall structure of the heating network 100 more stable and the heating more uniform.
