Through the arrangement of the above structure, that is, the utility model adds a cutting structure to the existing mixing blade 3, so that the mixing blade 3 can not only cut the food, but also mix the food, which greatly improves the cutting efficiency. At the same time, the corresponding cutting blade 2 can be reduced. Compared with the existing four-leaf blade structure, the utility model reduces the cost of manufacturing the blade assembly.

[0029] Furthermore, the first cutting portion 21 is arranged along the length direction of the cutting blade 2, the second cutting portion 31 is arranged along the length direction of the mixing blade 3, the first cutting portion 21 is provided with a first feeding groove 22, the second cutting portion 31 is provided with a second feeding groove 32, and the first feeding groove 22 of the cutting blade 2 and the second feeding groove 32 of the mixing blade B302 are staggered. Through the above-mentioned structural arrangement, that is, when the blade assembly rotates clockwise, the second cutting portion 31 of the mixing blade 3 behind the cutting blade 2 can supplement the cutting of the position where the cutting blade 2 has not cut, which is conducive to the full cutting of the pre-frozen food. In this embodiment, preferably, the second feeding grooves 32 of the mixing blade A301 and the mixing blade B302 are also staggered, which is more conducive to full cutting.

[0030] Furthermore, the bottom ends of the first cutting portion 21 and the second cutting portion 31 are located on the same reference plane, and the angle at which the mixing portion 33 of the mixing blade A301 is tilted upward relative to the reference plane is greater than the angle at which the mixing portion 33 of the mixing blade B302 is tilted upward relative to the reference plane.
