[0012] By adopting the technical scheme, the heating path of the transmission pipeline is increased, and the heat exchange area of the transmission pipeline is further increased.

[0013] Further, the transmission pipeline and the heating inner cavity wall, and the transmission pipeline and the internal heating element are both formed with an isolation gap.

[0014] By adopting the technical scheme, the isolation gap forms a uniform heating constant temperature zone between each other, avoiding local deformation of the component caused by excessive local temperature.

[0015] Further, the heating inner cavity is provided with a protective shell covering the outside of the internal heating element.

[0016] By adopting the technical scheme, the protective shell is provided to avoid the transmission pipeline from contacting and impacting the internal heating element due to external factors, thereby protecting and prolonging the service life of the internal heating element.

[0017] Further, the protective shell is connected to the shell and forms a mounting port for mounting the internal heating element in the protective shell inner cavity and the outside.
