Abstract
Description
Technical Field
[0001] This utility model relates to the field of meat grinder technology, specifically to a meat grinder that is easy to clean. Background Technology
[0002] A meat grinder is a basic kitchen appliance widely used in homes, canteens, and food processing plants. It is used to cut and grind meat, vegetables, and other ingredients into granules or minced form. A traditional meat grinder typically consists of a barrel, a built-in screw propeller (grinding screw), a fixed perforated plate, and a drive motor. During operation, the motor drives the screw to rotate, forcing the food fed into the hopper forward and ultimately extruding it through the holes in the perforated plate, completing the grinding process.
[0003] A search revealed a utility model patent with patent authorization announcement number CN220678076U, which discloses a meat grinder that is easy to clean. The meat grinder includes a grinding drum, a top cover hinged to the upper left end of the grinding drum, an insert block fixedly installed at the front end of the top cover, springs fixedly installed on both sides of the insert block, a limit block fixedly connected to one end of each spring, a protrusion fixedly installed at the front end of the grinding drum, and buttons slidably installed on both sides of the protrusion.
[0004] However, existing meat grinders typically connect the hopper and barrel using screws or simple snap-fit connections, making disassembly cumbersome and laborious. Food scraps easily remain at the connection points, creating unsanitary corners. Furthermore, at the discharge end, to obtain finer minced meat, a rotating cutter is usually added to the outside of the hinge plate. However, traditional designs fix the cutter directly to the end of the meat grinder screw. This structure makes disassembly and cleaning extremely inconvenient. Users cannot easily separate the meat grinder screw, hinge plate, and cutter assembly. Residual minced meat easily hardens in the gaps between components after drying, also creating unsanitary corners. Utility Model Content
