At this time, the cleaning rod 9 is located in the middle of the culture dish body 29, and the soft brush 25 is in contact with the inner wall of the culture dish body 29; then close the box door, and use the electric push rod 2 to extend and push the lifting seat 3 to move downward, so that the bottom end of the lifting seat 3 is adsorbed on the bottom of the culture dish body 29 through the suction cup, and at the same time, the lifting seat 3 continues to move downward and pushes the supporting seat 4 to move downward. When the supporting seat 4 moves downward under pressure, it can push the piston rod 6 to move downward. At this time, the reset spring 7 is compressed, and the piston rod 6 can push the piston plate 18 to move downward synchronously while moving downward, and then the piston plate 18 can be moved downward. The cleaning liquid inside the liquid storage tank 5 is squeezed out; the cleaning liquid is sent into the annular water storage seat 10 through the discharge pipe 11, and then sent into the multiple cleaning rods 9 through multiple water supply hoses, and the inner wall of the culture dish body 29 is rinsed through the flushing nozzle 26.

The rotating shaft 20 drives any rotating rod 22 to rotate through the transmission belt 21, and the rotating rod 22 drives multiple rotating rods 22 to rotate synchronously through the chain 23, so that the rotating disk 31 rotates, and synchronously drives the suction cup to rotate, so that the culture dishes can rotate synchronously, and multiple culture dishes can be self-rotated and rotated for flushing to ensure comprehensive cleaning. At the same time, more cleaning liquid can remain in the culture dish body 29, and the waste liquid generated by cleaning falls into the liquid collecting tank for collection and is discharged through the pipeline provided at the bottom of the liquid collecting tank; by providing an annular seat 28 and an annular rubber pad 27 on the bearing seat 4, the port of the culture dish body 29 can be abutted against the annular rubber pad 27, so that the port of the culture dish body 29 can be protected to avoid wear. , and when the culture dish rotates, the annular seat 28 can be synchronously rotated, effectively increasing the stability of the rotation of the culture dish body 29, which is convenient for rotary cleaning; and when the bearing seat 4 moves downward and pushes the piston rod 6 to move downward, the spiral rod 17 moves downward synchronously with the piston rod 6, and at this time, the spiral sleeve 30 rotates along the spiral rod 17, and the stirring rod 16 fixedly connected to the spiral sleeve 30 rotates synchronously. While the stirring rod 16 rotates, the stirring blades are used to stir and mix the cleaning liquid in the liquid storage tank 5 to avoid precipitation and ensure the effectiveness of the cleaning liquid; after the cleaning is completed, the electric push rod 2 contracts and drives the lifting seat 3 to move upward and away from the bearing seat 4, and the bearing seat 4 is pushed to move up and reset by the reset spring 7, and the piston plate 18 and the piston rod 6 are also reset at the same time;When the lifting seat 3 is away from the supporting seat 4, the culture dish body 29 on the supporting seat 4 is adsorbed by the suction cup and is in a suspended state.
