[0017] The circular shape of the circulation pipe increases the space within the pipe, allowing larger, flexible items, such as wet wipes or facial towels, to expand after falling to the bottom of the water chamber. This prevents items like facial towels from clumping together at the bend due to limited space and clogging the pipe, thereby facilitating the smooth flushing of wet wipes or paper towels down the pipe. Furthermore, the increased space at the bend in the water chamber prevents impurities from accumulating and clogging the pipe. Similarly, even impurities adhering to the inner wall of the pipe cannot be blocked by the circular shape, ensuring that the pipe remains unobstructed and preventing blockage. The connecting port on the isolation cover allows for the drainage of wastewater directly into the drainpipe through the connecting port when a portion of the pipe is blocked by items such as towels in the water chamber. This prevents wastewater from being discharged before the pipe is cleared, potentially exacerbating the blockage. This allows for normal wastewater discharge before the pipe is cleared, thus preventing inconvenience to the user. BRIEF DESCRIPTION OF THE DRAWINGS
