US Patent 11434630 Hair straining device

A straining device for bathtub drains to capture fallen hairs from water flowing into the drain. The straining device includes a tubular body that has multiple apertures in its wall and an open bottom. The body is divided into two parts that are pivotally coupled at the base through two opposite hinge joints. The tops of the two parts can be pivoted away from each other. To remove the trapped hairs, the tops of the two parts can be pulled away from each other resulting in dropping off the trapped hair on the outer surface of the straining device.
