The first preset flow rate may be set after the second preset flow rate is set, and the first preset flow rate may take different values according to actual needs, which is not limited herein, as long as the first preset flow rate is greater than the second preset flow rate, for example, when the second preset flow rate is 400ml/min, the first preset flow rate may be set to 500 ml/min. The first preset time period may also be set according to actual needs, for example, 2S, 3S, 4S or other values.

The heating body 30 is a stainless steel thick film heating tube, and the water outlet device 40 is a water outlet tap. When the quick heating water purifying dispenser is powered on and works, the processor 50 acquires and identifies the water taking operation input by a user, controls the water suction pump 20 to work to send water to the heating body 30 when the water taking operation is hot water taking, controls the heating body 30 to work to heat water flowing through the heating body 30 at the same time, and finally, the hot water flows out from the water outlet device 40.
