Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a cell culture constant flow replenishment device, including a base 1, a storage tank 2 is internally engaged with the base 1, a tank cover 3 is engaged with the top of the storage tank 2, an inlet cylinder 4 is fixedly connected to the bottom of the storage tank 2, the inlet cylinder 4 is fixedly connected to the bottom of the inlet hole 10, an operating box 5 is fixedly connected to the top of the inlet cylinder 4, a constant flow component 6 is provided on the outer surface of the operating box 5, the constant flow component 6 includes a drive body 61, an output rod 62 is fixedly connected to the output end of the drive body 61, a turntable 63 is fixedly connected to the top of the output rod 62, and the outer surface of the turntable 63 is attached to the rotating groove 13. The inner wall of the turntable 63 has a constant flow hole 64 on its outer surface. The outer surface of the operating box 5 is fixedly connected to a dust cover 7. The top of the dust cover 7 is fixedly connected to a culture chamber 8. The inner wall of the storage tank 2 has a liquid inlet hole 10. The inner wall of the operating box 5 is fixedly connected to a support column 11. The top of the support column 11 is fixedly connected to a flow guide plate 12. The flow guide plate 12 is located on the lower side of the liquid inlet cylinder 4. The flow guide plate 12 extends through the liquid outlet hole 14 into the interior of the dust cover 7 and the culture chamber 8. The outer surface of the operating box 5 has a rotating groove 13. The side of the operating box 5 near the dust cover 7 has a liquid outlet hole 14. The outer surface of the tank cover 3 has a cover hole 15.

[0023] In this embodiment, a base 1 is provided to support the storage tank 2, so that the nutrient solution in the tank can flow down from the bottom inlet hole 10 into the inlet cylinder 4. The inlet cylinder 4 and the guide plate 12 are both provided to introduce the nutrient solution into the culture chamber 8. The dust cover 7 is to prevent dust from falling into the nutrient solution during the flow into the culture chamber 8. The operation box 5 is provided, which serves the same purpose as the dust cover 7. On the other hand, a constant flow component 6 is provided inside the operation box 5 to control the constant flow of the nutrient solution. The output end of the drive body 61 in the constant flow component 6 passes through the through hole and is connected to the output rod 62 to drive the turntable 63 to rotate. The constant flow hole 64 is opened on the surface of the turntable 63. Liquid can only flow out when the constant flow hole 64 rotates to the outlet of the inlet cylinder 4, thereby achieving constant flow. The nutrient solution flows to the guide plate 12 and then flows into the culture chamber 8 through the outlet hole 14.

[0024] Example 2

[0025] like Figure 5 As shown, a sealing assembly 9 is provided on the outer surface of the bucket lid 3. The sealing assembly 9 includes a support plate 91. A cover plate 92 is provided on one side of the support plate 91. A moving groove 93 is opened on the outer surface of the support plate 91. A spring 94 is fixedly connected to the inner wall of the moving groove 93. A connecting plate is fixedly connected to one side of the cover plate 92. The outer surface of the connecting plate is fixedly connected to the top of the spring 94. The cover plate 92 fits against the top of the cover hole 15.

[0026] In this embodiment, a capping component 9 is provided. After the nutrient solution is added to the storage tank 2, it can automatically seal the cap hole 15. When opening, simply push the small protrusion on the outer surface of the cap plate 92 backward to move the cap plate 92 into the moving groove 93. The spring 94 is compressed. After the addition is completed, the support releases the small protrusion to put the cap plate 92 back on the surface of the cap hole 15.

[0027] Working principle:

[0028] like Figures 1-5 As shown, when the equipment is in use, the drive body 61 will be activated. The output end of the drive body 61 in the constant flow assembly 6 will pass through the operating box 5 and connect to the output rod 62, thereby driving the turntable 63 to rotate. The constant flow hole 64 on the surface of the turntable 63 can only discharge liquid when the constant flow hole 64 rotates to the outlet of the liquid inlet cylinder 4, thereby achieving constant flow. The nutrient liquid flows to the guide plate 12 and then flows into the culture chamber 8 through the liquid outlet hole 14. When replenishing the nutrient liquid in the storage tank 2, the small protrusion on the outer surface of the cover plate 92 is pulled back to move the cover plate 92 into the moving groove 93. The spring 94 is compressed. After the addition is completed, the support is released and the small protrusion can be moved back onto the surface of the cover hole 15.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
