Description

Technical Field

[0001] This application relates to the field of biological detection equipment technology, and in particular to a turbidity detection device for cell stock solutions. Background Technology

[0002] Turbidity sensors play an important role in the field of biological detection, especially in the detection of cell culture media. With the development of biotechnology, the requirements for the quality of cell culture media are increasing. As a key device, the performance of turbidity sensors directly affects the accuracy of detection results. Traditional methods mainly rely on periodic cleaning or replacement of sensor components, but these methods are complex to operate and inefficient, making it difficult to meet the needs of modern high-efficiency detection.

[0003] In existing technologies, the following methods are commonly used to solve the cleaning problem of turbidity sensors: First, manually disassembling and cleaning the sensor requires skilled operators and is a tedious process; second, soaking the sensor surface in chemical cleaning agents, which effectively removes dirt but may corrode the sensor material; third, using a removable protective cover structure, achieving cleaning by replacing the cover, but existing covers are mostly fixed designs, inconvenient to disassemble and reassemble, and have poor sealing. In addition, some technical solutions attempt to add mechanical cleaning devices to the outside of the sensor, such as brushes or scrapers, but these devices are often complex in structure, increasing the manufacturing cost of the equipment.

[0004] However, the aforementioned existing technologies generally suffer from problems such as inconvenience in operation, poor cleaning effect, or excessive cost. Especially in application scenarios where frequent replacement of test samples is required, they cannot effectively avoid cross-contamination, thus affecting the reliability of test results. Utility Model Content

[0005] To address the issues of cross-contamination, complex operation, and low efficiency associated with existing turbidity sensors in detecting cell stock solutions, this application provides a turbidity detection device for cell stock solutions.

[0006] The turbidity detection device for cell stock solution provided in this application adopts the following technical solution:

[0007] A turbidity detection device for cell stock solution includes a turbidity sensor body, an outer protective cover mounted on the turbidity sensor body, a self-cleaning device disposed between the turbidity sensor body and the outer protective cover, a cover ring detachably disposed on the outer protective cover, and a sapphire glass detachably disposed on the cover ring; wherein, the self-cleaning device includes a limiting strip disposed on the inner wall of the outer protective cover, a cleaning component slidably disposed on the limiting strip, and a drive ring disposed on the outer wall of the outer protective cover to drive the cleaning component to move along the axial direction of the outer protective cover.

[0008] By adopting the above technical solution, a self-cleaning function of the turbidity sensor is achieved during the detection of cell stock solution, effectively avoiding the impact of contaminant residue on the inner wall of the outer shield, thereby improving detection accuracy and reliability. The detachable design between the outer shield and the turbidity sensor body, combined with the replaceable sapphire glass structure, allows for convenient maintenance and replacement of the equipment, reducing operating costs and improving operational efficiency. The self-cleaning device removes residue from the inner wall of the outer shield, reducing the inconvenience of manual cleaning; the detachable ring and sapphire glass facilitate replacement and sterilization, further enhancing the hygiene and durability of the equipment.

[0009] Optionally, the cleaning component includes a cleaning ring that slides on the limiting strip and a rubber ring mounted on the cleaning ring, wherein the outer wall of the rubber ring is in contact with the inner wall of the outer protective cover, and the cleaning ring and the turbidity sensor body form a gap.

[0010] By adopting the above technical solution, after the test is completed, the residue on the inner wall of the outer protective cover is effectively removed to avoid contamination; at the same time, a gap is formed between the cleaning ring and the turbidity sensor to ensure that the cleaning process will not interfere with or damage the turbidity sensor, thereby improving the reliability and service life of the equipment.

[0011] Optionally, the cleaning ring is made of ferrous material, and the driving ring is made of magnetic material, with the cleaning ring and the driving ring magnetically attracted to each other.

[0012] By adopting the above technical solutions, we can ensure that the detection of cell stock solution is less contaminated, improve cleaning efficiency, simplify the operation process, and extend the service life of the turbidity sensor.

[0013] Optionally, the turbidity sensor body and the outer protective cover are connected by threads.

[0014] By adopting the above technical solution, convenient disassembly and assembly between the turbidity sensor body and the outer protective cover are realized, enabling rapid replacement of the outer protective cover and improving detection efficiency.

[0015] Optionally, the outer cover has a cylindrical structure, with an input port and an output port opposite to each other on the outer cover, and a support ring is fixed on the outer cover.

[0016] By adopting the above technical solution, a stable detection environment is provided for the cell stock solution, ensuring smooth fluid flow during the detection process and preventing the entry of external impurities, thereby improving the accuracy of the detection. The relatively open inlet and outlet ports on the outer protective cover facilitate the entry and exit of the cell stock solution, optimize the fluid flow path, and make the detection process smoother. The fixed support ring on the outer protective cover enhances the stability of the overall structure, facilitates the installation and fixation of the equipment, and improves the ease of operation.

[0017] Optionally, the cover ring has a groove circumferentially formed, and a clamping member for pressing against the sapphire glass is provided in the groove. The clamping member includes a rotating shaft installed on the groove. An abutment plate is rotatably provided at one end of the rotating shaft away from the side wall of the groove. A torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixed to the abutment plate, and the other end of the torsion spring is fixed to the groove.

[0018] By adopting the above technical solution, the sapphire glass can be securely installed on the cover ring, ensuring that it will not loosen or fall off during the testing process. The cooperation between the groove and the clamping member allows the sapphire glass to be subjected to the elastic force of the torsion spring, and the abutment plate applies a continuous clamping force to the sapphire glass, thereby improving the reliability of the installation. At the same time, it facilitates the disassembly and replacement of the sapphire glass, meets the hygiene requirements of the test, and effectively avoids the risk of contamination during the cell stock solution testing process.

[0019] Optionally, a sealing ring is provided on the cover ring, and the sealing ring abuts against the bottom of the outer cover.

[0020] By adopting the above technical solution, the sealing performance between the cover ring and the outer protective cover is effectively improved, preventing leakage of cell stock solution or entry of external contaminants during the testing process, thereby ensuring the accuracy of the test results.

[0021] Optionally, a rubber ring is also fitted onto the sapphire glass, and the rubber ring abuts against the inner wall of the cover ring; under the force of the torsion spring, the end of the abutment plate abuts against the rubber ring.

[0022] By adopting the above technical solution, the installation stability of sapphire glass is effectively enhanced, preventing it from loosening or falling off during use, thereby ensuring the reliability of the testing process. The rubber ring and the abutment plate are in contact to avoid scratching the surface of the sapphire glass.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a self-cleaning device between the outer cover and the turbidity sensor, the cleaning component is moved along the axis of the outer cover by the drive ring, which can effectively remove dirt from the inner wall of the outer cover, ensure cleanliness during the detection process, avoid cross-contamination, and improve the reusability.

[0025] 2. The outer protective cover and the turbidity sensor body adopt a detachable design, combined with sapphire glass and cover ring structure, which facilitates replacement and operation, improves detection efficiency and reduces the risk of contamination;

[0026] 3. The self-cleaning device drives the cleaning components through magnetic adsorption, which reduces the manufacturing cost of the equipment, while improving the ease of operation and saving time. Attached Figure Description

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0035] This application discloses a turbidity detection device for cell stock solution.

[0036] Reference Figure 1 and Figure 2As shown, the device includes a turbidity sensor body 1, an outer protective cover 2, a self-cleaning device 3, a cover ring 4, and a sapphire glass 5. The turbidity sensor body 1 and the outer protective cover 2 are connected by threads. The outer protective cover 2 is provided with an input port and an output port, and a support ring 6 is fixed thereon. The self-cleaning device 3 consists of a limiting strip 31, a cleaning component 32, and a driving ring 33. The cleaning component 32 is slidably mounted on the limiting strip 31, and the driving ring 33 drives the cleaning component 32 to move along the axis of the outer protective cover 2. The cover ring 4 is detachably mounted on the top of the outer protective cover 2. The cover ring 4 is provided with a groove 7 and a clamping component 8. The sapphire glass 5 is fixed by a rubber ring 10 cooperating with the clamping component 8. The turbidity sensor can quickly replace the outer protective cover 2, and at the same time, the self-cleaning device 3 achieves efficient cleaning of the inner wall of the outer protective cover 2, thereby effectively avoiding cross-contamination and improving the reliability of the detection results.

[0037] See Figure 4 and Figure 5 As shown, the outer protective cover 2 has a cylindrical structure, forming an internal cavity to accommodate the turbidity sensor body 1. A cover ring 4 is detachably installed at the port of the outer protective cover 2. The outer protective cover 2 is connected to the turbidity sensor body 1 by threads. The outer protective cover 2 can be made of transparent materials such as polycarbonate or acrylic resin to ensure the transmittance of detection light. A limiting strip 31 is provided on the inner wall of the outer protective cover 2. The limiting strip 31 is a long strip-shaped protrusion structure that extends along the axial direction of the outer protective cover 2, ensuring that the cleaning component 32 slides smoothly and without obstruction.

[0038] See Figure 5 As shown, the cleaning component 32 includes a cleaning ring 321 that slides on the limiting strip 31 and a rubber ring 322 mounted on the cleaning ring 321. The cleaning ring 321 is made of ferrous material, such as carbon steel or cast iron, and is circular in shape with a diameter slightly smaller than the inner diameter of the outer cover 2. The outer side of the cleaning ring 321 is integrally formed with a rubber ring 322, which is made of corrosion-resistant silicone rubber. Its cross-section is "O"-shaped, and it has good elasticity, allowing it to fit tightly against the inner wall of the outer cover 2 and scrape away dirt. The cleaning ring 321 and the turbidity sensor body 1 form a gap, maintaining a certain distance between them to avoid direct contact that could cause damage.

[0039] See Figure 5 As shown, the drive ring 33 is made of magnetic material and is slidably mounted on the outer wall of the outer cover 2. The drive ring 33 magnetically attracts the cleaning ring 321, causing it to slide along the limiting strip 31. The drive ring 33 is designed as a ring structure; the magnetic force acts on the cleaning ring 321, pushing it up and down along the limiting strip 31, thus achieving thorough cleaning of the inner wall of the outer cover 2. To enhance the magnetic attraction, the distance between the cleaning ring 321 and the drive ring 33 should be controlled, and the height of the limiting strip 31 must also meet the sliding requirements of the cleaning ring 321.

[0040] See Figure 3As shown, the cover ring 4 is mounted on the outer cover 2, and an annular groove 7 is formed on the cover ring 4. A retaining member 8 is installed in the groove 7. The retaining member 8 consists of a rotating shaft 81, a retaining plate 82, and a torsion spring 83. The rotating shaft 81 is installed in the groove 7, and the torsion spring 83 is sleeved on the rotating shaft 81. Its two ends are fixed to the retaining plate 82 and the side wall of the groove 7, respectively, providing elasticity to keep the retaining plate 82 pressing against the sapphire glass 5. After the sapphire glass 5 is embedded in the groove 7, a rubber ring 10 is fitted on its outer side. The rubber ring 10 fits tightly against the inner wall of the cover ring 4, further enhancing the sealing performance. Under the force of the torsion spring 83, the end of the retaining plate 82 abuts against the rubber ring 10, thereby firmly fixing the sapphire glass 5 to the cover ring 4.

[0041] See Figure 1 As shown, a sealing ring 9 is installed on the cover ring 4. The sealing ring 9 is made of corrosion-resistant fluororubber material, and its cross-section is "C" shaped. It abuts against the bottom of the outer cover 2 to prevent liquid leakage and increase the overall sealing performance of the outer cover 2. This prevents liquid from flowing out of the inner part of the outer cover 2 during the test and affecting the test results.

[0042] The implementation principle of the turbidity detection device for cell stock solution in this embodiment is as follows: the turbidity sensor body 1 and the outer protective cover 2 are assembled together by a threaded connection. A sealing ring 9 and a cover ring 4 are installed on the outer protective cover 2, and the sapphire glass 5 is fixed to the cover ring 4 by a clamping member 8. In use, the cell stock solution is injected into the outer protective cover 2 through the inlet. After the detection is completed, the cleaning ring 321 is driven by the moving drive ring 33 to slide along the limiting strip 31. The rubber ring 322 on the cleaning ring 321 scrapes the dirt on the inner wall of the outer protective cover 2. When the sapphire glass 5 is contaminated, it can be manually disassembled and removed for cleaning. When the outer protective cover 2 needs to be replaced, simply unscrew the threaded connection, remove the outer protective cover 2, and replace it with a new one. This achieves rapid replacement and efficient cleaning of the protective cover, effectively avoids cross-contamination, and improves detection efficiency and reliability.
