Abstract
The present invention relates to a food processor and a cover thereof. The food processor cover comprises a feed tube which extends upwardly from an upper cover surface, a safety rod assembly, a locking device, and a feed tube lid assembly pivotally mounted on said feed tube; said feed tube lid assembly includes a safety food entrance. By enlarging the size of feed tubes and food entrances, larger sized food is able to go through in larger quantities.
Claims10
A food processor cover comprising:
- an upper cover surface;
- a feed tube which extends upwardly from the upper cover surface;
- a safety rod assembly disposed on the outside of the feed tube, said safety rod assembly including an operating rod and a rod spring;
- a feed tube lid assembly including a feed tube lid pivotally mounted on the feed tube, and a movable sleeve;
- wherein said feed tube lid includes a through hole at an upper end thereof for receiving the movable sleeve inside the feed tube lid and enabling axial movements of the movable sleeve therein;
- wherein each end of the movable sleeve includes a limiting device, and the top of said movable sleeve forms a safety food entrance defined by a major axis and a minor axis, with an average of the major and minor axes being less than 2.5 inches (63.5 mm) and the major axis being less than 3 inches (76.2 mm);
- wherein said limiting device includes an upper limit ring and a lower limit ring respectively shaped in oval;
- wherein said upper limit ring and lower limit ring are integrally fixed on said movable sleeve;
- wherein the outer dimensions of the upper and lower limit rings are slightly larger than that of the through hole of the feed tube lid;
- wherein at least one protruding member is disposed at a bottom surface of the lower limit ring;
- wherein the periphery of said feed tube lid extends downwardly forming a lid brim with dimensions larger than that of the feed tube;
- wherein an upward edge of the through hole of the feed tube lid forms an upward neck;
- wherein said lid brim has a protruding member positioned to correspond with the operating rod;
- and
- wherein a square concave recess is disposed in the lid brim above said protruding member;
- and
- a locking device disposed on an upper end of said safety rod assembly;
- whereby when the feed tube lid assembly is in a closed state, the feed tube lid covers the feed tube, and the protruding member of the feed tube lid presses down the operating rod;
- and when the feed tube lid assembly is in an open state, the operating rod is urged to reset by means of the rod spring.
