[0071] The exhaust pipe 307 is made of high-temperature-resistant material.

[0072] The heat insulation layer 305 can prevent heat from escaping and ensure the heating speed inside the exhaust pipe 307.

[0074] The exhaust part includes a plurality of circumferentially and equally spaced air outlet pipes 304.
