AI Technical Summary

Technical Problem

The mixing components in existing cooking machines have a risk of detripping during cleaning, and are complex in structure and high in manufacturing costs.

Method used

An improved tool assembly is designed including a cutter plate assembly, a blade assembly and an anti-detachment piece. The blade assembly is detachable and rotates in the circumference of the tool axis through the anti-removal element to realize the anti-removal function of the blade assembly. The anti-removal parts cooperate with the positioning part at different positions to ensure that the blade assembly does not take off during use and can be easily removed during disassembly.

Benefits of technology

It realizes the rapid disassembly and anti-cutting functions of blade components in the cooking machine, reduces structural complexity and manufacturing costs, and improves the convenience and safety of use.

Abstract

The utility model relates to a knife assembly and a food processor. The cutter assembly comprises a cutter head assembly, a blade assembly and an anti-disengaging piece. The cutter head assembly comprises a cutter shaft, and the cutter shaft is provided with a positioning part. The blade assembly comprises a cutter sleeve and a blade arranged on the cutter sleeve, the cutter sleeve is provided with a cutter sleeve hole allowing the cutter shaft to penetrate through, and the cutter sleeve is detachably arranged on the cutter shaft in a sleeving mode and is in transmission connection with the cutter shaft in the circumferential direction. The cutter shaft is sleeved with the anti-disengaging piece, the anti-disengaging piece is located above the cutter sleeve, the anti-disengaging piece can rotate relative to the cutter shaft in the circumferential direction of the cutter shaft and can rotate to a first position and a second position, and in the first position, the anti-disengaging piece is matched with the positioning part and keeps relatively fixed with the cutter shaft in the circumferential direction of the cutter shaft; at the first position, the size of the cutter sleeve hole in at least one direction in the radial direction of the cutter shaft is smaller than that of the anti-disengaging piece in the direction, at the second position, the anti-disengaging piece is disengaged from the positioning part, the size of the anti-disengaging piece in any direction in the radial direction of the cutter shaft is smaller than that of the cutter sleeve hole in the direction, and the blade assembly is detachable. According to the scheme, the blade assembly can be quickly disassembled, and the blade can be prevented from falling off during working.
