As the height continues to decrease, due to the deformation of the elastic membrane, the central block, the elastic membrane and the sieve plate form a convex platform structure, so that the impurities slide outward. And because the top of the guiding rod is in a "丿" structure, the guiding rod limits and guides the roller, and can pull the arc-shaped baffle outward, so that the impurities can be discharged, achieving the purpose of automatic waste discharge.

[0017] 3. By setting structures such as a shield, a receiving hopper, and a discharge channel, the present invention can guide the discharged impurities through the shield and make them fall into the annular receiving table.
