Description

Technical Field

[0001] The utility model relates to a silent cover assembly structure of a food processor. Background Art

The food processor includes a main unit assembly and a damping assembly. The main unit assembly includes a mounting portion; the damping assembly includes a rotating shaft and a damping member, the rotating shaft and the damping member are both mounted on the mounting portion, and the damping member includes a damping portion protruding from the outer wall of the rotating shaft.

[0003] In the prior art, a blocking part is arranged to cooperate with a damping part. When the silent cover is opened to a preset angle or when the silent cover is ready to be completely closed, the blocking part and the damping part contact each other to achieve damping limit, thereby limiting the opening angle of the silent cover or preventing the silent cover from closing quickly and generating noise.

[0004] Based on the above, in the prior art, the rotating shaft and the damping member have complex shapes and need to be produced by injection molding, which has high mold opening costs and is not conducive to reducing production costs, and needs further improvement.

[0005] Meanwhile, in the prior art, the blocking part cooperates with the damping part, and only when the silent cover is opened to a preset angle or closed to a preset angle, the silent cover will stop rotating due to the cooperation between the blocking part and the damping part, thereby realizing position constraint. The problem with this structure is that when the blocking part moves between the two damping parts, it does not have any resistance, and there is still the problem of rapid rotation, which causes the blocking part to collide with the damping part and generate noise.
