The invention relates to the field of atomization tanks, in particular to an electromagnetic heating circulating atomization tank which comprises a heating device and an alarm device. The heating device comprises a heat guide tube fixedly arranged at the bottom of the atomization tank, an electromagnetic heating tube is arranged in the heat guide tube, and an electromagnetic heating coil is woundon the electromagnetic heating tube. A liquid level sensor is arranged at the position, in the same scale line as the top of the heat guide tube, in the atomization tank, and the liquid level sensor is connected with a control circuit of the electromagnetic valve on the atomization tank to control water inlet of the atomization tank. The alarm device comprises a single-chip microcomputer, a liquidlevel sensor and a communication device, wherein the liquid level sensor and the communication device are sequentially connected with the single-chip microcomputer. The technological defects that liquid can not be fully atomized, dry combustion is likely to happen and alarm can not be achieved are overcome. The electromagnetic heating circulating atomization tank has the performance of achievingfull atomization, preventing dry combustion and giving alarms for abnormal conditions of gas leakage and the like.
