The covering part 2122 may cover the entire outer wall of the fitting part 211 or may cover a partial outer wall of the fitting part 211. For example, in some embodiments, the shock absorbing sleeve 212 can cover the entire area of the mating portion 211 that is exposed, the entire area of the raised portion 2114 that is exposed, and the upper surface of the connecting portion 2113. The material of the shock-absorbing sleeve 212 may be an elastic material such as silicone rubber. The entire damper sleeve 212 may be provided to the clutch body 211 at a time by injection molding.

In the actual product, the thickness of shock attenuation cover is difficult too thin, otherwise easy damaged, and cooking machine during operation, its shock attenuation effect is not good, and cooking machine's noise is great. Of course, the thickness of the damping sleeve should not be too thick, and too thick a damping sleeve would increase the material cost required for production, and would easily cause an increase in the weight of the clutch assembly, and would also increase the vibration of the clutch assembly, thereby causing a loud noise.

In some embodiments, the thickness D2 of the covering part 2122 ranges from 0.5mm to 3mm, which can control the production cost well while ensuring good damping and noise reduction effects. Of course, the specific thickness of the covering part 2122 may be set according to specific conditions such as the size of the clutch assembly, which is not limited in the present application.

Of course, the portion b of the cover protrusion 2114, which engages the shock absorbing portion, may have a thickness substantially the same as that of the portion a. The upper clutch has a plurality of projections, prisms, or the like that correspond to the portion b of the clutch pack 21 that covers the boss 2114, so that the portion b of the clutch pack 21 that covers the boss 2114 can engage with the upper clutch to transmit rotation to the upper clutch when the food processor is in operation.

Further, the thickness of the covering part 2122 is smaller than that of the matching damping part 2121, so that the matching damping part 2121 can be well matched with the upper clutch and is not easily worn, and the weight of the clutch assembly is reduced as much as possible while the damping sleeve is ensured to be well attached to the clutch main body 211, so that the vibration of the clutch assembly in the working process is reduced, and the noise is reduced.

Further, the inner wall of the fitting portion 2111 may be provided with a plurality of recessed portions 2115 at intervals. A protrusion 2116 may be disposed within the recess 2115. Thus, when the damping sleeve 212 is arranged in an injection molding manner, the binding force between the damping sleeve 212 and the clutch body 211 can be effectively increased, so that the damping sleeve 212 is further prevented from falling out of the clutch body 211.

In the above embodiment, the shock attenuation cover laminate in the inner wall of cooperation portion 211 and the partial or whole region of the outer wall of cooperation portion 211 to the cladding is at least partial bellying 2114, makes the shock attenuation cover more firm with the combination of clutch main part, can prevent effectively that the shock attenuation cover from falling out in the cooking machine course of work, is favorable to improving consumption experience. In addition, after the clutch body 211 that becomes integrated into one piece through metal material casting or moulding plastics through engineering plastics, set up damping sleeve 212 through the mode of moulding plastics on clutch body 211, for the metalwork and the elastic component of processing the clutch respectively, and then reserve the production mode that the fit-up gap was assembled with the two again, can effectively improve production efficiency to reduction in production cost, and can more effectively prevent that damping sleeve from falling out in cooking machine working process.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
