The plurality of electric heating rings 12, the magnetic drive 13 and the temperature sensor are respectively electrically connected to the controller 14.

[0031] A limiting groove is provided at the center position of the bottom of the inverted conical groove 11. The magnetic bar 111 is provided with a limiting protrusion adapted to the limiting groove corresponding to the bottom of the V shape.
