Abstract: A water treatment system is provided with an untreated water reservoir having a cavity through which a filter assembly may traverse such that untreated water in the cavity passes through the filter assembly into a treated water reservoir. Removal of the filter assembly may be facilitated by a seal disengagement element operable to unseat a seal formed during efforts to direct untreated water through the filter assembly.

Abstract: The present disclosure provides a service life reminding system for a water bottle filter element. The service life reminding system for the water bottle filter element includes a one-way valve head, a mounting bracket, and a circuit board. The mounting bracket includes a first accommodating cavity. A portion of the one-way valve head is movably accommodated in the first accommodating cavity. A magnetic element is fixed in the mounting bracket. A magnetic sensor is arranged on the circuit board. Both of the circuit board and the magnetic sensor are accommodated in the one-way valve head. When the one-way valve head slides to abut against the mounting bracket, the magnetic sensor senses the magnetic element. When the one-way valve head slides away from the mounting bracket until the one-way valve head separates from the mounting bracket, the magnetic sensor is unable to sense the magnetic element.
