FILTER WITH PUSH OPEN AND SHUT OPERATION FOR SINK DRAINAGE HOLE

摘要

The present invention provides a filter for a sink drainage hole capable of easily performing the opening and closing operations by manufactured in a cylindrical division structure and performing the one-touch operation so that food leftovers are discharged to the lower part without overturning. According to the preferred embodiment of the present invention, the filter for a sink drainage hole is configured to include: a cylindrical flange which is formed in the upper part; an inlet port which is formed in the center of the flange; a filter main body that includes a fixed cylinder part which has a half-circle cross-sectional surface on lower side of the flange and has multiple output ports which are densely dispersed on the outer circumferential surface and that includes a lower bottom part which is integrally formed in the lower part of the fixed cylinder part; a rotation cylinder that has an output port which is densely distributed on the outer circumferential surface and which has a half circle-shaped cross section, has a closed lower bottom part, and is connected on the lower other side of the flange to be able to be opened and closed by rotating by a hinge pin; a operation grip that is provided in the upper part of the filter main body; and a spring means which is installed in the hinge pin so that the rotating cylinder is applied with rotating force in a closing direction.
