A1

A life reminding system for a filter element (70) of a water cup, comprising: a one-way valve head (10), a mounting bracket (20) and a circuit board (30); a first receiving cavity (21) is formed in the mounting bracket (20); a part of the one-way valve head (10) is movably accommodated in the first receiving cavity (21); a magnetic element (22) is fixed in the mounting bracket (20); a magnetic sensor (31) is provided on a circuit board (30); the circuit board (30) and the magnetic sensor (31) are received in the one-way valve head (10); when the one-way valve head (10) slides to push against the mounting bracket (20), the magnetic sensor (31) can sense the magnetic element (22); when the one-way valve head (10) slides towards a direction away from the mounting bracket (20) until the one-way valve head (10) is away from the mounting bracket (20) to remove the abutment, the magnetic sensor (31) cannot sense the magnetic element (22); the magnetic sensor (31) is used to sense the magnetic element (22) to count the number of uses of the filter element (70); and when the number of uses of the filter element (70) is within a prescribed range, an LED lamp bead (40) emits green light.
