Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 6 , the present invention provides two technical solutions:

[0031] The first embodiment: A vibration-damping centrifuge based on intelligent control, comprising a centrifuge housing 1, and a controller 2 fixedly mounted on the front side of the centrifuge housing 1 for controlling the operation of the device, the controller 2 being intelligently controlled by a preset program or connected to a PC for control, and further comprising:

[0035] The fixing mechanism 6 is arranged on the outside of the centrifuge housing 1 for fixing the position of the connecting plate 511, and it is convenient to take out the connecting plate 511 to replace the spring 59. The fixing mechanism 6 includes a limit ring 63 fixedly installed on the outside of the centrifuge housing 1, and the left and right sides of the top surface of the limit ring 63 are provided with positioning grooves 64. The outside of the centrifuge housing 1 is movably installed with a connecting ring 62 for fixing the position of the connecting plate 511, and the left and right ends of the top surface of the connecting ring 62 are threadedly installed with fixing screws 61 for fixing the position of the connecting ring 62. The connecting plate 511 The top surface of the connecting ring 62 is movable and passes through the inside of the movable groove 55 and is fixedly installed on the bottom surface of the connecting ring 62. The bottom surface of the connecting ring 62 is tightly attached to the top surface of the limiting ring 63. The bottom end thread of the fixing screw 61 passes through the top surface of the connecting ring 62 and extends to the inside of the positioning groove 64. The fixing screw 61 is rotated to pass through the connecting ring 62 and inserted into the inside of the positioning groove 64 to fix the position of the connecting plate 511. When the fixing screw 61 is rotated in the reverse direction and pulled out of the positioning groove 64, the connecting ring 62 can be picked up to take out the connecting plate 511 and replace the spring 59.

A plurality of mounting grooves 43 are provided on the inner side of the limiting cylinder 41. Limiting rollers 42 for improving the stability of the placement column 31 during rotation are movably mounted inside the plurality of mounting grooves 43. The plurality of mounting grooves 43 are evenly distributed on the inner side of the limiting cylinder 41 in a circular shape. The outer side of the limiting roller 42 is tightly attached to the outer side of the placement column 31. The limiting roller 42 can be tightly attached to the outer side of the placement column 31 to improve the stability of the placement column 31.

[0040] By setting the limiting cylinder 41 and the limiting roller 42, the stability of the placement column 31 during rotation can be improved. When in use, the brushless motor 33 is started to drive the placement column 31 to rotate to separate the liquid in the test tube. When the placement column 31 rotates, the limiting roller 42 will be tightly attached to the outer side of the placement column 31 to prevent the placement column 31 from shaking, and the stability is good.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0042] When in use, the user opens the cover of the centrifuge housing 1, then places the test tube containing liquid into the placement slot 32, then closes the cover of the centrifuge housing 1, starts the brushless motor 33 through the controller 2 to drive the placement column 31 to rotate and separate the liquid. When the placement column 31 rotates, the limiting roller 42 will be close to the outer side of the placement column 31 to prevent the placement column 31 from shaking, and the elastic force of the spring 59 will push the abutment plate 57 to press against one side of the movable block 54, and the movable block 54 will push the cross plate 52 to make the pressure plate 51 press against the top surface of the placement column 31, thereby reducing the vibration generated when the placement column 31 is separated and improving the stability of the placement column 31 when rotating. When the spring 59 is fatigued and worn for a period of time, the rotating fixing screw 61 is unscrewed from the inside of the positioning slot 64, and then the fixing screw 61 is pulled to drive the connecting ring 62 to pull the connecting plate 511 out of the movable slot 55 through the notch 56 for replacement.
