[0028] A centrifuge for food detection, comprising a machine body 1 and a backing plate 2. The backing plate 2 is installed at the bottom end of the machine body 1, and a removal mechanism and a centrifugation mechanism are arranged inside the machine body 1.

[0029] The centrifugation mechanism includes a rotating unit and a fixing unit.

[0030] The fixing unit includes a placement hole 403, a compression spring 404, a resisting plate 405, a connecting rod 406 and a limiting ring 407. The placement hole 403 is opened at the top end of the placement disc 402. The compression spring 404 is connected to the inner wall of the placement hole 403. The compression spring 404 and the resisting plate 405 are distributed in a triangular shape inside the placement hole 403, thereby improving the fixing efficiency of the reagent tube. The resisting plate 405 is installed at the other end of the compression spring 404. The shape of the resisting plate 405 is an arc-shaped elastic plate, which is suitable for fixing the reagent tube. The connecting rod 406 is fixedly installed at the top end of the placement disc 402, and the limiting ring 407 is installed at the top end of the connecting rod 406.

[0031] Embodiment Two:

[0032] Based on Embodiment One: The rotating unit includes a chassis 401 and a placement disc 402. The chassis 401 is installed at the top end of the fixing plate 304. A driving motor is installed inside the chassis 401, thereby enabling the placement disc 402 to have a certain source of rotational power. The placement disc 402 is arranged at the top end of the chassis 401. The connection at the bottom end of the placement disc 402 is connected to the rotating end of the driving motor. Thus, the placement disc 402 is driven to rotate by the operation of the driving motor, thereby improving the centrifugation efficiency of the device.

[0033] The removal mechanism includes a moving groove 301, an inner groove 302, a transmission part 303, a fixing plate 304, a fixing rod 305, a support column 306 and a buffer spring 307. The moving groove 301 is opened at the bottom end inside the machine body 1. The inner groove 302 is opened at the side of the moving groove 301. The transmission part 303 is arranged inside the moving groove 301. The fixing plate 304 is installed at the fixed end of the transmission part 303. The fixing rod 305 is installed inside the inner groove 302. The support column 306 is installed at the fixed end of the transmission part 303. The inner wall of the other end of the support column 306 abuts against and is slidably connected to the outer wall of the fixing rod 305. The support column 306 plays a role in supporting and limiting the fixing plate 304, making its movement more stable. The buffer spring 307 is connected to the outer wall of the fixing rod 305. The buffer springs 307 are symmetrically distributed at both ends of the fixing rod 305. The buffer springs 307 play a certain buffering role, further improving the stability of the movement of the fixing plate 304.

[0034] Embodiment Three: Heat dissipation holes are opened on the side of the chassis 401, and the heat dissipation holes penetrate through the side of the chassis 401 to its interior. By opening the heat dissipation holes, the heat generated by the operation of the driving motor can be discharged from the heat dissipation holes, preventing the temperature inside the chassis 401 from being too high and damaging the driving motor, and extending its service life.

[0035] During use, when placing the reagent tube, the operation of the transmission member 303 is controlled by the controller. The transmission member 303 includes a drive motor, a rotating rod, and a moving seat. The operation of the drive motor drives the rotation of the rotating rod, and the inner wall of the moving seat is threadedly connected to the outer wall of the rotating rod. Thus, the rotation of the rotating rod drives the movement of the moving seat on its outer wall. Therefore, under the limit support of the support column 306 and the fixed rod 305, the placement tray 402 can be quickly moved out of the machine body 1, which facilitates the taking and placing of the reagent tube and improves the detection efficiency. During the process of placing the reagent tube, due to the elastic action of the compression spring 404, the pressing plate 405 clamps and fixes the reagent tube, and it is also convenient to place reagent tubes of different sizes. The limiting ring 407 plays a role in limiting and improves the stability of the detection.
