However, during use, the flip-up type drain is often adsorbed by objects and automatically opens the opening or is stuck by microparticles such as fine sand, and has problems such as insufficient sealing. In view of the above problems, a utility model patent with publication number: CN214245954U discloses a bouncing core, which is arranged in a drain hole of a bathroom drain device and drives a cover to close or open the drain hole; the bouncing core comprises a bouncing seat, a bouncing core, a positioning piece and a spring; the bouncing seat is provided with a receiving groove for the bouncing core to bounce up and down, and the side wall of the receiving groove is provided with a positioning groove; a bouncing positioning track is provided on one side of the bouncing core, and a slot for accommodating the spring is provided on the other side; the bouncing positioning track is provided with a closing positioning point and an opening positioning point, and the bouncing core is pressed to move downward. The spring is moved and compressed, and the restoring force of the spring drives the bouncing core to move upward. The bouncing core moves up and down, thereby changing the position of the positioning piece in the bouncing positioning track, and the positioning piece switches to the closed positioning point and the open positioning point. This technical solution realizes the opening and closing switching of the drain hole of the bathroom drain device through the bouncing core, but the slide groove will be exposed during the up and down movement of the bouncing core of this solution, which is easy to accumulate debris and cause pressing jams, and the overall bouncing structure is relatively complicated. The sliding cooperation between the bouncing core and the accommodating groove requires the cooperation of multiple parts such as positioning pieces and screws, and the assembly precision requirements are high and the assembly is relatively cumbersome.
