Abstract

The invention discloses a device and a method for preparing and filtering drinking water based on a magnetized filter element, which relate to the technical field of filtration and comprise a connecting seat; the device comprises a first filter plate, a second filter plate, a third filter plate and a fourth filter plate, and a telescopic unit which is arranged on a connecting seat and is used for driving the first filter plate, the second filter plate and the third filter plate to move towards a direction far away from the fourth filter plate so as to enable a shaftless spiral sheet to be in an elastic extension state. In the invention, when foreign matter impurities are cleaned, the first filter plate, the second filter plate and the third filter plate are driven by the telescopic unit to move in the direction away from the fourth filter plate, so that the shaftless spiral sheet is elastically stretched and deformed, and the gaps between the activated carbon particles and the magnetized particles are increased, so that the foreign matter impurities can flow out to the water outlet through the gaps between the activated carbon particles and the magnetized particles, thereby realizing the removal of the foreign matter impurities, prolonging the filter element replacement period and reducing the replacement frequency of the filter element.
