Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The present invention is described below with reference to fig. 1-5:

an upper cover mechanism is used as an upper cover of a centrifugal machine and comprises an outer shell layer 1, a supporting layer 2 and an inner shell layer 3 which are fixedly connected in sequence, and further a heat preservation layer 4 is arranged between the inner shell layer 3 and the supporting layer 2 for heat preservation.

An annular convex edge 301 is arranged in the middle of the inner shell layer 3, the annular convex edge 301 is matched with the opening of the centrifuge drum, and an annular heat-insulating convex edge 401 sleeved with the annular convex edge 301 is arranged on the heat-insulating layer 4, so that a better heat-insulating effect is achieved.
