The top cover 5 is fixedly connected with three groups of fixing devices 6 arranged in a circular array. Each group of fixing devices 6 abuts against the centrifuge cylinder 1.

[0030] Due to the arrangement of the centrifuge cylinder 1, the first cleaning device 2, the second cleaning device 3, the connecting rod 4, the top cover 5, the fixing device 6 and the driving device 7, when it is necessary to clean the inner cavity of the centrifuge cylinder 1, the staff first snaps the top cover 5 onto the opening of the centrifuge cylinder 1, and then rotates the three groups of fixing devices 6 so that the three groups of fixing devices 6 are all against the centrifuge cylinder 1. At this time, the top cover 5 can be firmly against the opening of the centrifuge cylinder 1. When the top cover 5 is firmly against the opening of the centrifuge cylinder 1, the first cleaning device 2 connected to the connecting rod 4 will be against the inner cavity side wall of the centrifuge cylinder 1, and the second cleaning device 3 connected to the bottom end of the connecting rod 4 will be against the bottom end of the inner cavity of the centrifuge cylinder 1. Then, the connecting rod 4 is driven to rotate by the output shaft of the driving device 7 installed on the top cover 5, so that the first cleaning device 2 can be rotated along the inner cavity side wall of the centrifuge cylinder 1, and the second cleaning device 3 can be rotated along the inner cavity bottom end of the centrifuge cylinder 1. At this time, the inner cavity of the centrifuge cylinder 1 can be effectively cleaned.

Since the first spring 23 is always in a compressed state, the first brush 22 can be kept close to the inner cavity side wall of the centrifuge cylinder 1, and then the first brush 22 can have a better cleaning effect on the inner cavity side wall of the centrifuge cylinder 1. When the first brush 22 rotates along the inner cavity side wall of the centrifuge cylinder 1, the first telescopic rod 24 can prevent the first spring 23 from deforming, and then the first spring 23 can be protected to a certain extent.

Since the second spring 33 is always in a compressed state, the second brush 32 can be kept close to the bottom end of the inner cavity of the centrifuge cylinder 1, so that the second brush 32 can have a better cleaning effect on the bottom end of the inner cavity of the centrifuge cylinder 1. When the second brush 32 rotates along the bottom end of the inner cavity of the centrifuge cylinder 1, the second telescopic rod 34 can prevent the second spring 33 from deforming, so that the second spring 33 can be protected to a certain extent.

[0038] The stopper 61 is fixedly connected to one end of the threaded rod 62 .

[0039] Due to the arrangement of the stopper 61 and the threaded rod 62, when the top cover 5 is buckled in the opening of the centrifuge cylinder 1, the staff rotates the three groups of threaded rods 62 in sequence, so that the three groups of threaded rods 62 respectively drive the corresponding stopper 61 to move toward the centrifuge cylinder 1, and make the three groups of stopper 61 abut against the centrifuge cylinder 1 at the same time, so that the top cover 5 can be firmly buckled in the opening of the centrifuge cylinder 1.
