In this embodiment, a secondary flow tube 200 is wound around the periphery of a main flow tube 100, and the secondary flow tube 200 is wound from the lower end to the upper end of the main flow tube 100. The lower end of each secondary flow pipe 200 is a first water diversion end 220, and the upper end is a water diversion end 210. The sub-flow pipes 200 are sequentially connected in series, that is, the water separating end 210 of the previous sub-flow pipe 200 and the first water separating end 220 of the next sub-flow pipe 200 are connected through the first water pipe 400.

The electric heating module 300 extends in the pipe length direction of the main flow pipe 100, and is capable of sufficiently heating the liquid or gas flowing through the main flow pipe 100 and the sub-flow pipe 200 and increasing a heating path. The electric heating module 300 heats the main flow pipe 100 while heating the sub-flow pipe 200 with heat energy to the outside.

The water is gradually heated while flowing in the subsidiary flow pipe 200, and the spiral subsidiary flow pipe 200 sufficiently extends the heating flow path of the water. Simultaneously, water flows from bottom to top, and the water can be distributed in the auxiliary flow pipe 200 for flow heat exchange. Finally, water enters the main water inlet main end 101 of the main flow pipe 100 from the auxiliary water outlet main end 201 of the auxiliary flow pipe 200 group, then flows along each main flow pipe 100 and the second water pipe 500 in sequence, the water is gradually heated to a steam state in the main flow pipe group, and the steam is finally discharged from the main steam outlet main end 102 of the main flow pipe group for users to use. The steam flows from bottom to top in the main flow pipe 100, and the liquid water remaining in the steam flows downwards under the action of self gravity and is heated to a steam state in the main flow pipe group again. When the steam is discharged from the main steam outlet main end 102 of the main steam pipe group, the liquid water content in the discharged steam can be reduced as much as possible.

In some embodiments of the present utility model, a plurality of electric heating modules 300 are disposed on the outer wall of the main flow pipe 100 in a distributed manner along the circumferential direction of the main flow pipe 100.
