[0002] The development direction of the product is to make the mixing components in the food processor detachable and washable. Therefore, the mixing components in most food processors adopt a detachable structure. However, the detachable mixing components also have the risk of the blade falling off. Summary of the invention

[0003] The present application provides an improved knife assembly and a food processor, wherein the knife assembly is detachable and has a low risk of the knife falling off.

[0004] A knife assembly, comprising:

[0005] A knife shaft is provided with a mounting portion, the mounting portion extends downward from the top of the knife shaft and gradually deflects along the circumference of the knife shaft, the deflection direction is set to be opposite to the rotation direction of the knife shaft, the mounting portion includes a terminal located at the bottom of the knife shaft, the extension direction of the terminal and the extension direction of the knife shaft are at an angle α, 0<α≤90°; and

[0006] A detachable cutter head comprises a cutter sleeve and a blade arranged in the cutter sleeve, wherein the cutter sleeve and / or the blade are provided with a matching portion, wherein one of the mounting portion and the matching portion is a recessed portion and the other is a convex portion, wherein the convex portion and the recessed portion are slidably matched with each other during the process of the cutter sleeve being mounted on the cutter shaft, and the cutter head is provided with an installation position mounted on the cutter shaft, wherein the matching portion is located at the end.

[0007] In this solution, the cutter head can be sleeved on the cutter shaft along the extension direction of the mounting portion.
