The bouncing machine core is inverted, where one end with a protruding tip facing upwards and the other end facing downwards, so as to avoid the interference between the protruding tip and a drainage outlet. The water filter basket assembly includes a sleeve, a water filter basket, and a sealing ring. The sleeve is mounted at the top of the bouncing machine core in a sleeving manner, and wraps the protruding tip of the bouncing machine core. The water filter basket and the sealing ring are mounted on the sleeve in sequence from top to bottom. According to the application, through the adoption of the inverted bouncing machine core, which solves the problem that a traditional bouncing drainer is not suitable for some vegetable washing basins.
