The present invention relates to a drain sieve for the sink, and the main drain hole is formed at a constant interval in the opened and the side surface perimeter and the bottom surface top as a metal material, is fixed to the side of the upper end of the body 180 is possible handle rotated to the left or right in the configuration sink drain sieve for that, the main body of titanium dioxide (titanium dioxide, TiO ₂₎ is applied to the bottom surface of the main body the center of the top and bottom is inserted a quartz tube is through-formed with a through hole on the inner side a conical shape is mounted, the bottom surface of the quartz tube equipped with a main body has the bottom face is configured with a ring-shaped fixing member which is inserted in a quartz tube passing through the bottom surface in close contact fixed to the lower surface.
Therefore, the sink drain according to the present invention siege is an effect that prevents the propagation of such odor and mold and that may be caused by food particles bacteria can be hygienically managed kitchens environment can discard collected without immediately dispose of the garbage no hassle to throw away every time you wash the dishes because corruption does not have the advantage of providing convenient, easy to manage a simple structure, and do not lift the maintenance economics, germs and bacteria that occur in the siege it will no longer use flux or detergent to kill harmful organisms is the greenest invention useful for protecting the environment.
