Extruding screw and food processor

Abstract

The invention provides an extruding screw and a food processor. The extruding screw comprises a screw body, a screw shaft and a wear resistant piece; one end of the screw shaft is arranged in the screw body, and the other end of the screw body extends out of the first end of the screw body; the wear resistant piece is arranged in the end surface of the first end of the screw body in an integratedway; and the cross-sectional area of the screw body is increased and then decreased from the first to second ends of the screw body. The wear-resistant piece is additionally arranged in the position where wearing is serious of the extruding screw so as to enhance the wear resistance of the screw, and further during rotation of the screw, wearing is reduced, and the problem that the extruding screwtends to wearing is solved. Via the structure, wearing of the screw in single time during use is reduced, and thus, the screw is not worn seriously after long-time use of the processor, performance reduction of the processor due to wearing of the extruding screw can be avoided, and further the processor still has a relatively high performance after long time.

Description

technical field [0001] The invention relates to the field of household appliances, more specifically, to an extruding screw and a food processor. Background technique [0002] Extrusion screws of existing juicers on the market are generally made of plastic injection molding. This process solves the problem of product cost. However, during the use of this type of juicer, especially when squeezing hard fiber fruits and vegetables, it will The extrusion screw causes a lot of wear, which can lead to a decrease in the performance of the entire machine. [0003] Therefore, how to design a kind of extrusion screw that can reduce wear and tear, still can guarantee the complete machine performance of juicer after using for a long time has become a problem to be solved urgently at present. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. [0005] To this end, it is an object of the present inve...
