[0053] S1. The heating wire includes heating wire a and heating wire b. After passing the wire passing hole 4 on the left side of the first region 1, heating wire a and heating wire b are respectively wound between multiple upper wire winding grooves 5 and multiple lower wire winding grooves 6 in the first region 1.

[0068] In some embodiments, an adjustment hole 8 for a single heating wire to pass through is provided on one side of the wire threading hole 4. When assembling the heat source, the end direction of the heating wire can be adjusted through the adjustment hole 8 to make the wire threading of the heating wire more orderly.

[0069] The heating wires shown as solid lines in the accompanying drawings of the specification are located on the front sides of the first region 1 and the third region 2, and the heating wires shown as dotted lines are located on the back sides of the first region 1 and the third region 2.
