Double-layer net grinding pressing mechanism and double-layer net grinding pressing juice extractor

The invention relates to the technical field of domestic electrical appliance products, in particular to a double-layer net grinding pressing mechanism and a double-layer net grinding pressing juice extractor. The juice extractor comprises a motor box, a motor, a middle cover, a grinding pressing mechanism and an upper cover, wherein the grinding pressing mechanism is composed of a filter screen and a rotor; the filter screen is of a double-layer filter screen structure, and comprises an upper filter screen and a lower filter screen; the rotor comprises an upper coarse grinding part and a lower coarse grinding part; the motor is mounted in the motor box; the middle cover is fixed on the motor box; the filter screen is mounted in the middle cover; the rotor is positioned in the filter screen; the middle cover is covered with the upper cover, and the upper cover is used for hooding the filter screen and the rotor; the rotor is connected to the motor through a rotor shaft. The filter screen and the rotor are designed to form a structure with an upper part and a lower part corresponding to each other, and a grinding pressing structure is newly added through combination; compared with a traditional structure, fruit residues inside the double-layer net grinding pressing mechanism is great in stress, high in juice extraction speed and high in juice yield, the content of fibers is also improved, and the juice extractor has a more obvious juice extraction effect for raw materials with hard shells such as beans.
