The temperature sensor 4 is electrically connected to a temperature measuring probe 6 located in the heater housing 2 through a wire, and the temperature sensor 4 and the electric heating tube 3 are both electrically connected to the controller 5;

[0024] The working principle and effect achieved by this embodiment are as follows: an intelligent temperature control mechanism is provided, and the temperature measuring probe 6 on the temperature sensor 4 detects the water temperature in the heater housing 2 in real time. Once the water temperature is abnormally high, a signal is transmitted to the controller 5, and the controller 5 controls the electric heating tube 3 to be turned off to stop heating. In this way, the effect of intelligent temperature control heating is achieved, explosion caused by excessively high internal water temperature is avoided, and safety hazards are reduced.
