Description

Novel stirring sword subassembly and cooking machine Technical Field The utility model relates to the technical field of food processing, in particular to a novel stirring knife assembly and a cooking machine. Background This section provides only background information related to the present application so as to enable those skilled in the art to more thoroughly and accurately understand the present application, and is not necessarily prior art. The food processor integrates the functions of beating soybean milk, grinding dry powder, squeezing juice, beating meat stuffing, planing ice and the like, and is a household appliance for preparing various foods such as juice, soybean milk, jam, dry powder, planing ice, meat stuffing and the like. Most of the existing cooking machines on the market cannot be disassembled to clean the knife assemblies, and the knife assemblies cannot be disassembled but fall down easily during slurry pouring, so that the existing cooking machines are troublesome. For this purpose, application number 202420588293.3 discloses a stirring knife assembly and a cooking machine, wherein the stirring knife assembly comprises a rotating shaft and a knife assembly, the rotating shaft comprises a driving section, the driving section comprises a plurality of convex edges extending in the up-down direction, the convex edges gradually deflect along the circumferential direction of the driving section, the knife assembly is detachably arranged on the rotating shaft and comprises a knife sleeve and a knife blade fixed on the knife sleeve, the knife blade and/or the knife sleeve is provided with a driving hole matched with the driving section, the driving hole comprises a plurality of convex angles extending vertically in the up-down direction, the convex angles are respectively in butt fit with the convex edges, one of the rotating shaft and the knife assembly is provided with a first magnetic part, the other one of the rotating shaft and the knife assembly is provided with a second magnetic part which is attracted with the first magnetic part, or the other one of the rotating shaft and the knife assembly is made of magnetic materials.
