[0002] Garbage disposers are a kitchen appliance that is becoming increasingly popular among home users. When you put vegetable stalks, bones, leftovers, and other kitchen waste into the inlet of the garbage disposer, the motor drives the blade group to rotate, cuts and grinds the waste until it is crushed, and then discharges it into the sewer through the garbage outlet.

[0003] Various common kitchen wastes usually have a high water content or have water attached to the surface. However, commonly used garbage disposers cannot achieve solid-liquid separation of garbage. After the garbage is crushed, the water in the garbage will be discharged from the garbage outlet together with the solid waste, making the processed garbage usually more viscous and easy to adhere to the inner wall of the sewer. When used for a long time, it is easy to cause sewer blockage. In addition, the processed garbage is only discharged directly into the sewer and cannot be recovered and recycled, which is not conducive to environmental protection and resource recovery.
