Each third connecting through hole is uniformly distributed, and each first electric heating strip of the first electric heater 12 is matched and connected with each third connecting through hole; each of the fourth connecting through holes is equally distributed. For example, the vapor enters the hydrogen production reaction space 13, and gradually approaches the second baffle 14 due to the continuous accumulation of the vapor in the hydrogen production reaction space 13, and finally passes through each uniformly distributed fourth connecting through hole, so that the vapor is also uniformly distributed, and then generates hydrogen with the hydrogen production catalyst under the heating condition of each first electric heating strip, and finally is discharged from the hydrogen outlet.
