One side of the arc-shaped plate 10 is provided with an arc-shaped groove 11 corresponding to the avoidance hole 9. The wire winding grooves 7 are arranged on both sides of the arc-shaped plate 10. After the heating wire 6 winds around both arc-shaped plates 10 at the same time, the arc-shaped plates 10 are butted to form a bowl-shaped heating component 3, which simplifies the wire winding process.

[0025] In some embodiments, the upper shell 1 includes a bottom surface part and a surrounding part. The bottom surface part is in a circular structure of a plane, a bulge or a concave shape. The edge of the bottom surface part extends upward to form a surrounding part. The inner side of the surrounding part has an arc surface.
