Description

Technical Field

[0001] The utility model relates to the technical field of juice extraction equipment, in particular to a juice extraction mechanism. Background Art

[0002] Juicers have become an indispensable food processor for many families. The machine can crush fruits or vegetables and separate juice from pomace to obtain clear juice. In the past, centrifugal juicers crushed food through a fast-rotating blade and threw pomace and juice onto a filter. The juice flowed out through the holes on the filter, and the pomace remained on the filter, achieving pomace-juice separation. After use, the pomace on the filter was removed. The disadvantage of this technology is that during use, the pomace on the filter accumulates more and more, which affects the dynamic balance of the filter and makes a lot of noise. When the pomace accumulates to a certain extent, it will block too many holes in the filter, reducing the juice yield. It is not suitable for processing more food.

[0003] At present, centrifugal juicers mainly discharge residues in two ways: residue collection type juicer and side discharge type juicer. The residue collection type centrifugal juicer mainly generates centrifugal force through the high-speed rotation of the filter screen to achieve residue-juice separation, and collects the flying residue into a fixed residue collection bin. However, since the space of the residue collection bin is fixed, the residue collection bin will be full after the machine has worked for a certain period of time, and it needs to be stopped and cleaned frequently. If the accumulation is too full and not cleaned in time, the residue will enter the juice collection bin and flow out into the juice cup with the juice, affecting the taste and concentration of the juice. For the side discharge type centrifugal juicer, it is necessary to add an arc-shaped residue discharge pipe on the side of the juicer to guide the residue to fly out from the side along the residue discharge channel. The juice yield is low and there are limitations on product appearance and space design. Utility Model Content
