[0038] The effect achieved is that when the contact rod 39 moves, one end of the contact rod 39 fits against the inclined surface of the conical ring 23, so the conical ring 23 is lifted upward, thereby driving the lifting rod 22 to lift upward, so that the lifting plate 7 lifts the storage container 2 upward.

[0039] like Figure 3 , Figure 5 and Figure 6 As shown, the locking mechanism includes two spring clamps 37, and side openings 36 are provided on the inner walls of both sides of the protective sleeve 1 near the top edge. The two spring clamps 37 are correspondingly rotatably connected between the inner walls of the side openings 36. The interior of the protective sleeve 1 is located below the annular collecting chamber 20 and has two side chambers 34. One end of the two side chambers 34 penetrates to the inner bottom surface of the side opening 36. Side push rods 35 are provided inside the two side chambers 34.

A hexagonal hole 25 is provided on the inner bottom surface of the adjusting chamber 21. The bottom of the lifting rod 22 is slidably connected between the inner walls of the hexagonal hole 25. The hexagonal hole 25 is communicated with the two side chambers 34, and the other ends of the two side push rods 35 are correspondingly fixed on the outer surface of the lifting rod 22.

[0040] The effect achieved is that, as the lifting rod 22 is lifted upward, the side push rod 35 is driven to slide upward. During the upward sliding process of the side push rod 35, the top side fits with the side of the spring clamp 37, so that the side of the spring clamp 37 can be pushed toward the inside of the protective sleeve 1, so that it is engaged in the limit opening 8 on the storage container 2, and at the same time, cooperates with the upward lifting force of the lifting plate 7, so that the storage container 2 can be limited and locked.

[0041] like Figure 1 , Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the feedback assembly includes a floating plate 12, the floating plate 12 is located below the fixed sleeve 11, a guide plate 17 is fixed on the top of the floating plate 12, the top of the guide plate 17 slides through the inside of the fixed sleeve 11, a push block 16 is fixed on the top of the guide plate 17, the push block 16 is located inside the fixed sleeve 11, a limited cavity 14 is provided on the inner wall of the storage container 2, an insertion rod 13 is arranged inside the limited cavity 14, one end of the insertion rod 13 slides through the outer surface of the storage container 2, and one end of the insertion rod 13 The other end of the plug rod 13 slides through the interior of the fixed sleeve 11, and a triangular block 15 is fixed to the other end of the plug rod 13. The inclined surface of the triangular block 15 fits with the outer surface of one side of the push block 16. A limiting ring 18 is fixed to the outer surface of the plug rod 13. The limiting ring 18 is slidably connected between the inner walls of the limiting cavity 14. A flow channel 19 is opened on the inner wall of the protective sleeve 1. The bottom of the flow channel 19 extends to the inside of the annular collecting cavity 20, and the top of the flow channel 19 extends to the outer surface of the protective sleeve 1 The outer surface of the protective sleeve 1 is fixed with a feed pipe 5, and the feed pipe 5 is connected with the top of the flow channel 19. The interior of the protective sleeve 1 is provided with a hexagonal cavity 26, and a through hole 28 is provided on one side of the hexagonal cavity 26. One end of the through hole 28 penetrates into the interior of the protective sleeve 1, and the through hole 28 is connected with the flow channel 19. One end of the insertion rod 13 is opposite to one side of the through hole 28. A hexagonal plate 33 is slidably connected between the inner walls of the hexagonal cavity 26, and a guide rod 27 is fixed on one side of the hexagonal plate 33. One end of the guide rod 27 is fixed to the inner wall of the hexagonal cavity 26. The end slides through the outside of the protective sleeve 1, and two copper sheets 32 are fixed on the outer surface of the guide rod 27. Two notches 30 are provided on the inner wall of the other side of the hexagonal cavity 26 at the connection of the guide rod 27. Copper blocks 31 are provided inside the two notches 30. The two copper blocks 31 correspond to the two copper sheets 32 and fit each other. A second spring 29 is fixed between one side of the hexagonal plate 33 and the inner wall of one side of the hexagonal cavity 26. An alarm 4 is provided on the base 3, and the alarm 4 is electrically connected to the two copper blocks 31.

[0042] The effect achieved is that, in the process of injecting culture solution into the storage container 2, when the liquid level of the culture solution in the storage container 2 rises to a certain height, the floating plate 12 will be pushed upward, and the push block 16 will be driven to move upward during the upward sliding of the floating plate 12. During the upward movement of the push block 16, one side of the push block 16 fits with the inclined surface of the triangular block 15, so the triangular block 15 will be pushed to one side, and then one end of the insertion rod 13 will be pushed to slide into the through hole 28. After one end of the insertion rod 13 completely enters the flow channel 19, the flow channel 19 can be cut off. At the same time, when one end of the insertion rod 13 enters the flow channel 19, the hexagonal The plate 33 is pushed outward, and during the pushing process, the copper block 31 and the copper sheet 32 ​​are fitted together, thereby turning on the alarm 4 and generating an alarm, reminding people that the culture solution inside the storage container 2 has been filled. When the liquid level of the culture solution inside the storage container 2 drops, the upward buoyancy of the float plate 12 is reduced, and the second spring 29 is reset at this time, pushing the rod 13 to the other side until the inclined surface on the rod 13 slides into the interior of the flow channel 19. Since there is always culture solution flowing downward inside the flow channel 19, when the thrust of the downward flow of the culture solution acts on the inclined surface of the rod 13, the rod 13 can be pushed in the opposite direction, thereby making the flow channel 19 conductive.

[0043] Working principle: When using the device, the feed pipe 5 is connected to the external culture fluid supply pipeline. After the storage container 2 is placed inside the protective sleeve 1, the culture fluid is supplied to the inside of the annular collecting chamber 20 through the feed pipe 5. During the sliding process of the storage container 2, the inner wall of the docking groove 9 contacts the inclined surface of the conical block 42, thereby pushing the conical block 42 into the storage chamber 41, thereby driving the contact rod 39 to move so that the through hole 43 and the drainage hole 40 are connected to each other. At the same time, when the fixing column 6 completely slides into the docking groove 9, The guide hole 10 is connected with the drainage hole 40, and the culture fluid flows from the drainage hole 40 on the top surface of the annular collecting chamber 20 into the guide hole 10, and finally flows into the storage container 2. When the contact rod 39 moves, one end of the contact rod 39 fits with the inclined surface of the conical ring 23, so the conical ring 23 is lifted upward, and then the lifting rod 22 is driven to lift upward, so that the lifting plate 7 lifts the storage container 2 upward. Since the lifting rod 22 is driven to slide upward during the upward lifting process, the side push rod 35 is driven to slide upward during the upward sliding process of the side push rod 35. By fitting one side of the top with one side of the spring clamp 37, the one side of the spring clamp 37 can be pushed into the protective sleeve 1 so that it is engaged in the limit opening 8 on the storage container 2. At the same time, with the upward lifting force of the lifting plate 7, the storage container 2 can be limited and locked. In the process of injecting culture solution into the storage container 2, when the liquid level of the culture solution in the storage container 2 rises to a certain height, the floating plate 12 will be pushed upward. In the process of the floating plate 12 sliding upward, the push block 16 will be driven to move upward. The upward movement of the push block 16 During the process, since one side of the push block 16 fits with the inclined surface of the triangular block 15, the triangular block 15 will be pushed to one side, and then the one end of the plug rod 13 will be pushed to slide into the through hole 28. After one end of the plug rod 13 completely enters the flow channel 19, the flow channel 19 can be cut off. At the same time, when one end of the plug rod 13 enters the flow channel 19, the hexagonal plate 33 will be pushed outward. During the pushing process, the copper block 31 and the copper sheet 32 ​​fit each other, and then the alarm 4 is turned on to generate an alarm, reminding people that the culture solution inside the storage container 2 is full.
