A guide pipe 75 is fixed between the upper connecting sleeve 73 and the lower nozzle 74.

[0028] The culture structure includes a culture pool 81 and a concave-convex surface 82. The culture pool 81 is opened in the middle of the upper end surface of the culture body 8, and the concave-convex surface 82 is opened on the outer side of the upper end surface of the culture body 8. An air guide ring tube 83 is fixed inside the culture body 8, and an air outlet pipe 84 is fixed on the air guide ring tube 83. A one-way air valve 85 is fixed at the port of the air outlet pipe 84.

[0030] Furthermore, one end of the spring piece 33 is fixedly connected to the inner wall of the slide groove 31, and the other end is fixedly connected to the slider 32. The limiting ring 34 is slidably connected to the base 3 through the slide groove 31 and the slider 32, so that the slider 32 can move back and forth inside the slide groove 31 by extending or contracting the spring piece 33, so that the slider 32 can drive the limiting ring 34 to move back and forth.

[0031] Furthermore, the discharge pipe 6 is movably connected to the upper connecting sleeve 73, and the top cover 2 is movably connected to the outer shell 1 through the discharge pipe 6 and the upper connecting sleeve 73.

[0035] During use, the nutrient solution required for culture is poured into the distributor 4 through the feeding pipe 5, and the distributor 4 can evenly transport the nutrient solution to the discharge pipe 6 at different positions, and the nutrient solution inside the discharge pipe 6 is discharged from the lower nozzle 74 through the upper sleeve 73 and the guide pipe 75, and the nutrient solution is sprayed on the guide slope 72, and the nutrient solution on the guide slope 72 splashes onto the inner wall of the outer shell 1, and then flows downward along the inner wall of the outer shell 1 to the concave-convex surface 82, and the nutrient solution on the concave-convex surface 82 slowly flows into the culture tank 81, so that the nutrient solution can be evenly poured into the culture tank 81, and impact damage to the cells in the culture tank 81 can be avoided, and the nutrient solution can flow in a wave shape in the process of flowing from the concave-convex surface 82 to the culture tank 81, and when the nutrient solution flows from the convex part to the concave part of the concave-convex surface 82 During the process on one side, the nutrient solution is prevented from contacting the intersection of the convex and concave parts of the concave-convex surface 82, that is, the nutrient solution flows in a waterfall shape during this process, so that the nutrient solution will not contact the port of the air outlet pipe 84. At the same time, the external oxygen generator can transport oxygen to the air outlet pipe 84 at different positions through the air guide ring tube 83, and discharge it through the one-way air valve 85. The discharged oxygen can be evenly mixed with the nutrient solution flowing in a waterfall shape and flow into the culture tank 81. When the nutrient solution flows into the inside of the culture tank 81, the vibration motor 36 is started to drive the culture body 8 to vibrate through the outer shell 1, and the outer shell 1 can always be limited on the base 3 through the limiting ring 34 so that it will not shift. Therefore, shaking the culture body 8 by vibration can make it easier for oxygen to dissolve in the culture solution, shorten the cell culture time, and improve the culture efficiency.
