After the folding subassembly is folded among this technical scheme, expand through motor control folding subassembly to and pivot drive filtering component resets to the water filter tank in, filters once more. This technical scheme's other system of straining is in the use, folding assembly rotates and when folding, and the water liquid level after filtering in the water filter box is located the filtering component below, avoids folding assembly to rotate and folding in-process rivers undulant impurity that leads to on the filtering component drops in aqueous once more. Preferably, the fan-shaped filter assembly is horizontally arranged, and the cross section of the filter box is matched with the shape of the fan-shaped filter assembly. Preferably, a first filter screen is further arranged in the water filtering tank and is positioned below the filtering component.

Furthermore, the filtering component comprises a plurality of filtering units consisting of a first rotary drum and a fan-shaped filter screen, the end part of the fan-shaped filter screen is fixed on the outer side wall of the first rotary drum, the first rotary drums are sleeved on the rotary shaft along the axial direction of the rotary shaft, the rotary shaft is parallel to the axial line of the first rotary drum, a third annular chute is arranged on the inner side wall of the first rotary drum along the circumferential direction of the first rotary drum, a first telescopic rod is arranged on the side wall of the rotating shaft, a second sliding block which slides along a third annular sliding groove is arranged at the end part of the first telescopic rod, external teeth are arranged on the side wall of the first telescopic rod along the circumferential direction of the rotating shaft, a toothed belt which is matched with the external teeth is arranged on the inner side wall of the first rotating cylinder along the circumferential direction of the first rotating cylinder, a movable tooth is arranged at one end of the toothed belt, an arc-shaped sliding groove is arranged on the inner side wall of the first rotating, a first sliding block which slides along the arc-shaped sliding groove is arranged at the bottom of the movable gear, and a first spring is arranged between the side wall of one side of the first sliding block and the end part of the arc-shaped sliding groove; when filtering component changed fold condition into by the tiling state, the pivot rotated and made fan-shaped filter screen be close to the setting tank, until the movable tooth on external tooth and every first rotary drum matches, made the movable tooth drive first slider extrusion first spring.
