An automatic water-adding vaporization including a pot body main body, a heat-generating component installed on the pot body main body, a water pump connected to the pot body main body, a control circuit for controlling the water pump, a temperature acquisition board and a water-depletion-and temperature-sensing element installed on the temperature acquisition board. One end of the temperature acquisition board is either connected to the heat-generating component or to a position of the pot body main body in proximity to the heat-generating component. The remaining parts of the temperature acquisition board are away from the pot body main body. The water-depletion- and temperature-sensing element is installed at a position on the temperature acquisition board away from the pot body main body. The water-depletion- and temperature-sensing element is connected to the control circuit.
