Description

Technical Field

[0001] This utility model relates to the field of culture device technology, and in particular to a culture device drainage management structure. Background Technology

[0002] In modern biological culture technology, the culture vessel is a core piece of equipment, and the stability and reliability of its drainage management structure directly affect the safety of the culture process and the quality of the culture. In applications such as cell culture and microbial culture, the culture process inevitably produces substances such as cell debris, impurities, or crystals.

[0003] Most existing culture vessel drainage management structures only have simple drainage ports and lack effective filtration and anti-clogging mechanisms. In actual operation, cell debris, impurities, or crystals can easily accumulate at the drainage port, causing blockage of the drainage channel. Once blocked, it not only prevents the drainage process from proceeding normally, prolonging the culture cycle and increasing labor and time costs, but may also cause pressure imbalance inside the culture vessel, disrupting the stable culture environment, thereby affecting the growth status of the culture, leading to reduced culture activity, decreased yield, or even experimental failure or production accidents. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing methods where cell debris, impurities, or crystals easily accumulate at the drain outlet during actual operation, leading to blockage of the drain channel. Once blocked, the draining process cannot proceed normally, prolonging the culture cycle and increasing labor and time costs. It may also cause pressure imbalance inside the culture vessel, disrupting the stable culture environment and affecting the growth status of the culture, resulting in reduced culture activity, decreased yield, or even experimental failure or production accidents. Therefore, this invention proposes a culture vessel draining management structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A culture vessel drainage management structure includes a culture vessel body with a funnel-shaped waste liquid pool inside. A connecting nozzle is connected through the bottom of the culture vessel body, and an extension tube is fixedly installed at the bottom of the connecting nozzle. Locking mechanisms are provided on both sides of the outer wall of the connecting nozzle. A filter tube is installed on the extension tube through the locking mechanisms. A sliding groove is provided on both sides of the inner wall of the filter tube, and a filter component for filtering cell debris, impurities, or crystals is installed in the sliding groove.

[0007] Preferably, a valve is provided on the connector.

[0008] Preferably, the filter assembly includes a first filter screen, a slide rod is fixedly provided on the top of the first filter screen, a second filter screen is slidably provided on the slide rod, and a waterproof pad is provided at the bottom of both the first filter screen and the second filter screen.

[0009] Preferably, a connecting plate is fixedly provided at the top of the filter tube, the connecting plate has a connecting hole, and the bottom of the connecting nozzle has a connecting port.

[0010] Preferably, the locking mechanism includes a protrusion, a sliding cavity, a spring, a limiting rod, and a limiting ring. The protrusion is fixedly disposed on the outer wall of the connecting nozzle, the sliding cavity is disposed inside the protrusion, the spring is sleeved on the limiting rod, the limiting rod is slidably disposed on the protrusion, and the limiting ring is fixedly disposed on the limiting rod.

[0011] Preferably, one end of the spring is fixedly connected to the inner wall of the sliding cavity, and the other end of the spring is fixedly connected to the limiting ring. The limiting ring is disposed in the sliding cavity and slidably engaged, and the limiting rod passes through the outer wall of the protrusion and slidably engaged.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In use, this utility model can form a scientific and efficient drainage path by setting a funnel-shaped waste liquid pool inside the culture vessel body, and connecting it with a bottom-through nozzle, extension tube and filter tube. The funnel shape design of the waste liquid pool can guide the waste liquid to flow quickly to the bottom, reducing the residue of waste liquid in the culture vessel body. At the same time, with the filter components in the filter tube, it can effectively intercept cell debris, impurities or crystals, preventing them from accumulating at the drainage port, ensuring the long-term unobstructed drainage channel, avoiding drainage interruption and extended culture cycle due to blockage, and reducing labor and time costs.

[0014] 2. In use, the valve on the connecting nozzle can be used to flexibly control the drainage process. It can be opened when drainage is needed and closed when not needed, effectively preventing accidental leakage of waste liquid. At the same time, when the filter component becomes clogged and needs to be cleaned or replaced, the valve can be closed to prevent liquid leakage inside the culture vessel, ensuring operational safety, preventing internal pressure imbalance caused by abnormal drainage, maintaining a stable culture environment, and reducing the risk of experimental failure or production accidents.

[0015] 3. When in use, the locking mechanism on the connecting nozzle of this utility model consists of a protrusion, a sliding cavity, a spring, a limiting rod, and a limiting ring. The structure is simple, stable, and reliable, enabling quick installation and disassembly of the filter tube. It facilitates the inspection, replacement, and maintenance of the filter tube and filter components, thereby improving the practicality and flexibility of the entire drainage management structure.

[0027] Furthermore, a connecting plate 14 is fixedly installed on the top of the filter tube 6. The connecting plate 14 is made of reinforced ABS engineering plastic, which has excellent impact resistance. A connecting hole 15 is opened on the connecting plate 14, and a copper threaded sleeve is embedded in the connecting hole 15 to improve the durability of the connection. A connecting port 16 is opened at the bottom of the connecting nozzle 3. The edge of the connecting port 16 is chamfered to facilitate quick alignment and installation.

[0028] Furthermore, the locking mechanism 5 includes a protrusion 17, a sliding cavity 18, a spring 19, a limiting rod 20, and a limiting ring 21.
