Drain strainer

Abstract

We provide a drain strainer. [Solution] The system includes a filter net 10 and a position regulating member 20. The filter net is used to filter impurities from the wastewater in the drain strainer, and the position regulating member is used to regulate the position of the filter net. By regulating the position of the filter net with the position regulating member, the filter net is prevented from moving due to the impact force of the water flow when the drain strainer drains water. The filter net filters impurities from the wastewater in the drain strainer, preventing them from flowing into the sewer. Furthermore, the filter net also has a blocking effect, so if valuables are accidentally dropped into the drain strainer, the filter net will block them, preventing them from falling into the sewer and becoming irretrievable. In addition, the filter net and the position regulating member work together to easily replace the filter net when the drain strainer is not draining water. The filter net can be replaced with a new one simply by removing the filter net and the position regulating member together from the drain strainer. This configuration is simple and easy to replace.

With the above configuration, the height of the first connecting portion 32 is lower than the height of the second connecting portion 33, the height of the second connecting portion 33 is lower than the height of the third connecting portion 35, and the height of the third connecting portion 35 is lower than the height of the fourth connecting portion 37. A height difference is formed by the first connecting portion 32, the second connecting portion 33, the third connecting portion 35, and the fourth connecting portion 37, and the height of the connecting portion that is closer to the first groove 31 is lower. This allows water from the ground to flow into the first groove 31 more quickly, shortening the drainage time.

[0025] In this embodiment, the filter net 10 includes a mesh body 11 that is provided so as to be inclined and recessed from the periphery toward the center. The mesh body 11 is provided with a plurality of first filter holes 12. The mesh body 11 is provided with a blocking plate 13, which is positioned at the center of the mesh body 11. The position regulating member 20 is fitted onto the mesh body 11. The outer edge of the mesh body 11 is folded back, passing sequentially through the first through hole 311 and the second through hole 41. The outer edge of the mesh body 11 after folding passes sequentially between the inner wall of the first groove 31 and the contact surface 53, and through the first through hole 311, and is positioned outside the first through hole 311. With this configuration, the blocking plate 13 makes it easy to handle the mesh body 11 and allows confirmation of the orientation of the mesh body 11. The mesh body 11 passes through the first through hole 311 and the second through hole 41 in sequence, then comes into contact with the contact member 51, and then passes through the first through hole 311 again, thereby forming a fixing structure and fixing the position of the filter screen 10. If the diameter of the first filter hole 12 is smaller than the diameter of the contact surface 53, the contact surface 53 causes the filter screen 10 to come into contact with the inner wall of the first groove 31, thereby fixing the position of the filter screen 10. If the diameter of the first filter hole 12 is larger than the diameter of the contact surface 53, the contact portion 54 passes through the first filter hole 12 and comes into contact with the inner wall of the first groove 31, and the first filter hole 12 is fitted into the contact portion 54, thereby fixing the position of the filter screen 10.
