Water purification water dispenser filter element service life detecting method

The invention provides a water purification water dispenser filter element service life detecting method, and belongs to the technical field of purification equipment. The water purification water dispenser filter element service life detecting method is characterized in that under the condition that the water in a water purification box of a water purification water dispenser is full, heating operation is performed; when the water level in the water purification box descends, a water pump prepares water; after the water of the water purification box is full, the total water pump water preparation water quantity L and the water pump water preparation time t are obtained; the water purification flow rate calibration value u=L/t is calculated; a plurality of groups of calibration values are obtained; the average value is taken for obtaining the current time water purification flow rate U=(u1+u2+u3+and so on+un)/n; data is stored in a memory; meanwhile, the current time water pump work time T is obtained; the cu
