[0016] Beneficial effects:

[0017] 1. The utility model arranges a partition, which can divide the heating chamber into two chambers. When cold water enters the interior of the limiting pipe through the water inlet pipe, the connecting pipe and the guide pipe, the limiting pipe can make the cold water flow from the bottom of the inner cavity of the heating chamber. The electric heating pipe can heat the water inside the heating chamber. After the heating is completed, the water can be discharged from the top of the inner cavity of the heating chamber through the water outlet pipe. In this way, the cold water can be located at the bottom of the inner cavity of the heating chamber after entering the heating chamber. At the same time, the heat conduction is limited by the partition, which reduces the influence of the cold water on the water temperature above the inner cavity of the heating chamber, thereby improving the heating efficiency when the heating device works continuously.
