Strainer
The present invention relates to a sink strainer including a supporting plate and multiple annular chains. A drain hole is positioned at the center of the supporting plate. The annular chains are interconnected to form a mesh, with its outer edge connected to the supporting plate and surrounding the drain hole. The present invention effectively addresses the problem found in conventional non-reusable strainers.
1. A strainer comprising a supporting plate and multiple annular chains, wherein:
a drain hole is provided in the center of the supporting plate; and
the annular chains are connected to each other to form a mesh, and an outer edge of the mesh is connected to the supporting plate, and the outer edge of the strainer surrounds the drain hole, wherein the supporting plate is provided with multiple connection holes arranged in a circumferential array on an outside of the drain hole; and the annular chains located at the outer edge of the mesh extend through the corresponding connection holes respectively to connect the mesh to the supporting plate.
2. The strainer according to claim 1 , wherein the connection hole has a diameter ranging from 2 mm to 8 mm.
3. The strainer according to claim 1 , wherein each of the annular chains is in a circular shape and has a diameter ranging from 8 mm to 12 mm.
4. The strainer according to claim 1 , wherein an outer periphery of the supporting plate is provided with a transition portion, and an upper surface of the transition portion is in the form of a curved shape gradually inclined downward from an inside of the supporting plate to an outside of the supporting plate.
5. The strainer according to claim 1 , wherein the supporting plate is in a circular shape.
6. A strainer comprising a supporting plate and multiple annular chains, wherein:
a drain hole is provided in the center of the supporting plate; and
the annular chains are connected to each other to form a mesh, and an outer edge of the mesh is connected to the supporting plate, and the outer edge of the strainer surrounds the drain hole,, wherein the mesh comprises multiple annular chain sets arranged sequentially from an inside of the mesh to an outside of the mesh, and the annular chain sets comprise the annular chains arranged in a circumferential array and connected to each other; and each of the annular chain is engaged to the corresponding two annular chains in the annular chain set on the outside of the mesh.
7. The strainer according to claim 6 , wherein the mesh further comprises a center ring, and the annular chains in an innermost part of the annular chain sets are connected to the center ring.
