The first plane is a plane constructed along the first direction and the second direction. The height direction of the wavy shape is perpendicular to the distribution direction of the mounting rod.

7. An electric heating wire assembly according to claim 6, characterized in that, When the electric heating wire is used on the side wall, the shape of the electric heating wire projected onto the second plane is a U-shape with the opening facing outwards, and the open end of the U-shape is between the fiber block and the closed end of the U-shape; when the electric heating wire is used on the top plate of the heating cover, the shape of the electric heating wire projected onto the second plane is a W-shape, and the open end of the W-shape is between the fiber block and the closed end of the W-shape. The second plane is the plane formed by the distribution direction of the mounting rod and the third direction.

8. An electric heating wire assembly according to claim 7, characterized in that, When the electric heating wire is used in the top plate of the heating shroud, it further includes: The second heat insulation tube is hung on the second end and is parallel to the first heat insulation tube. The second heat insulation tube is made of heat insulation material and overlaps the W-shaped recessed position so that the electric heating wire is located between the second heat insulation tube and the fiber block.

9. A method for fixing an electric heating wire assembly, applied to an electric heating wire assembly according to any one of claims 6-8, characterized in that, The method includes: Connect the first mounting component and the second mounting component so that the fiber block is mounted on the inner wall of the heating shroud; The third surface of the fiber block is cut to form a slit to expose the mounting rod. The third surface and the first surface are two surfaces of the fiber block that are arranged opposite to each other. The first ends of the plurality of hooks are inserted into the cut and hung on the mounting rod such that the second ends of the hooks are outside the fiber block; The second end of each hook is attached to the crest and trough of the wave to secure the heating wire to the third surface.

10. A method for fixing an electric heating wire assembly according to claim 9, characterized in that, The electric heating wire fixing device includes the heat insulation plate and the electric heating wire. When used on a side wall, before the second end of each hook is hung at the crest and trough of the wave to fix the electric heating wire to the third surface, the method further includes: The heat insulation plate is hung on the second end of the hook so that the electric heating wire is between the ends of the second end of the hook on the heat insulation plate; When the electric heating wire is used to heat the top plate of the heating shroud, and when at least one hook is present in the W-shaped recessed position including the second heat insulation tube, the method further includes, after hooking the second end of each hook to the crest and trough of the wave shape to fix the electric heating wire to the third surface: The second heat insulation tube is overlapped with the first heat insulation tube at the recessed position of the W shape; The second end of the hook is hung on the second heat insulation tube so that the second heat insulation tube presses down on the electric heating wire.
