[0002] At present, there are many types of food processors on the market, such as soymilk machines, wall breaking machines, juicers, baby food processors, etc. The mixing blades of different food processors have different structures. In order to improve the mixing effect, the blades of the mixing blades are usually designed as a multi-layer mixing blade structure, which has a complex structure and high cost.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN215914275U discloses a crushing knife assembly of a food processor, wherein the crushing knife assembly includes a knife shaft, a first crushing knife, a first sleeve and a second crushing knife, the knife shaft includes a main body, the first crushing knife, the first sleeve and the second crushing knife are fixed to the main body, the first sleeve is located between the first crushing knife and the second crushing knife, and the knife shaft is configured to drive the first crushing knife and the second crushing knife to rotate to whip the food. The crushing knife assembly can adjust the distance and number between the crushing knives (including the first crushing knife and the second crushing knife) of the crushing knife assembly by replacing the first sleeve of different heights or increasing the number of the first sleeve, so that the crushing knife assembly has a better effect of whipping the food. However, the crushing knife assembly has structural deficiencies, its structure is complex, the cost is high, and the assembly gap between the knife shaft, the sleeve and the crushing knife is easy to enter the supplementary food mud residue, which is not easy to clean, and the user experience is not good, resulting in many market user complaints.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content
