Preferably, a first steam heating channel is defined between the first baffles on the two sides outside the notch, a second steam heating channel is defined between the first baffles on the two sides and the second baffles on the two sides respectively, a third steam heating channel is defined between the second baffles on the two sides and the third baffles on the two sides respectively, a fourth steam heating channel is defined between the third baffles on the two sides, and the two sides form an M-shaped steam heating flow channel on the two sides from the inside of the first steam heating channel to the top end gap of the first baffle, to the bottom end gap of the second baffle, to the top end gap of the third baffle and finally to the inside of the fourth steam heating channel.

Preferably, the second baffle and the third baffle are positioned adjacent to the position of the electric heating pipe.

Preferably, an upper cover sealing ring is arranged between the barrel-shaped shell and the upper cover, and a lower cover sealing ring is arranged between the barrel-shaped shell and the lower cover.

The invention has the advantages that: structural design is reasonable, two electric heating pipe settings are at the inside center of casing, can effectively reduce the heat loss, improve heat utilization rate, improve steam output volume, it at first gets into the barrel-shaped inner wall at casing center to intake, evenly to both sides heating channel transport, the distribution of intaking is even, both sides heating channel is M shape and arranges, can effectively increase heating area, improve the steam dryness fraction, collect at last from the outlet duct output, electric heating pipe's position design can effectively heat each steam delivery channel, the incrustation scale of giving vent to anger can effectively be reduced in inlet tube and the unsettled design of outlet duct, prevent to block up.
