Abstract
Description
Technical Field
[0001] This utility model relates to the field of fully automated specific protein analyzers, and specifically discloses a cleaning device for cleaning dilution cups. Background Technology
[0002] In the field of clinical testing, fully automated specific protein analyzers have become important tools for disease diagnosis due to their advantages such as high sensitivity, high throughput, and high degree of automation. During the testing process, these instruments require the use of dilution cups to precisely dilute and mix samples or reagents. To ensure the accuracy and reliability of the test results and avoid cross-contamination, these dilution cups must be thoroughly and effectively cleaned after each use to remove residual samples, reagents, reaction products, and potential interfering substances.
[0003] Existing cleaning devices typically involve precise injection of cleaning fluid, multi-step rinsing, and waste fluid removal to meet high cleanliness standards and ensure that subsequent testing batches are not affected by previous residues, thereby maintaining the high accuracy and repeatability of the entire testing system. However, existing cleaning devices rely solely on the liquid rinsing process and completely lack physical wiping of the inner wall of the dilution cup after cleaning. This results in the inability to completely remove liquid film residues, and hydrophobic contaminants or viscous residues cannot be effectively peeled off and removed by liquid flow impact alone, leading to incomplete cleaning. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a cleaning device for cleaning dilution cups, so as to solve the technical problem that existing dilution cup cleaning devices do not thoroughly clean the inner wall of the dilution cup.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for cleaning dilution cups, comprising a fully automatic specific protein analyzer body, a dilution cup rotating disk for driving the dilution cup to rotate on the fully automatic specific protein analyzer body, an L-shaped lifting frame on the fully automatic specific protein analyzer body, a fixed platform installed on the L-shaped lifting frame, the L-shaped lifting frame for driving the fixed platform to rise and fall, a limit frame fixedly connected to the fixed platform, a liquid addition cleaning device for adding cleaning solution to clean the dilution cup on the fixed platform, two rinsing devices for rinsing the dilution cup on the fixed platform, a re-absorption device for extracting residual liquid in the dilution cup on the fixed platform, and an inner wall scraping and suction device for scraping and extracting residual liquid on the inner wall of the dilution cup on the fixed platform.
[0006] In this scheme, the cleaning solution is first injected into the dilution cup by the liquid addition and cleaning device for preliminary chemical decomposition; then, two high-pressure water rinsings are performed sequentially by two rinsing devices to effectively remove residual cleaning agent; then, the residual liquid is completely drained by the re-suction device; finally, the inner wall of the dilution cup is physically scraped by the inner wall scraping and suction device and the residual liquid and impurities are simultaneously suctioned. This device thoroughly cleans the inner wall of the dilution cup through a combination of multiple liquid flow rinsings and mechanical scraping and suction, through four cleaning stages.
[0007] Furthermore, the inner wall scraping and suction device includes a first fixed tube, a first mounting hole is provided on the fixed platform, the first fixed tube is slidably disposed in the first mounting hole, a first fixed plate is installed on the outer wall of the first fixed tube, a first spring is provided on the first fixed plate, the end of the first spring away from the first fixed plate is fixedly connected to the limiting frame, a first limiting post is provided on the fixed platform, the end of the first limiting post away from the fixed platform passes through the first fixed plate and extends into the central hole of the first spring, a first liquid suction tube for suctioning liquid in the dilution cup is provided in the first fixed tube, a wall scraping block is installed on the first liquid suction tube, and the outer diameter of the wall scraping block is adapted to the inner diameter of the dilution cup.
[0008] In this design, the outer diameter of the scraper block is precisely matched with the inner diameter of the dilution cup, enabling it to form a tight sliding contact with the inner wall of the dilution cup. This effectively removes liquid film residues, hydrophobic contaminants, and viscous reaction products that are difficult to remove with traditional rinsing. While the scraper block moves downward to scrape off the residue on the inner wall, the first suction tube immediately and simultaneously suctions the scraped liquid and impurities. This achieves a highly efficient cleaning effect through simultaneous scraping and suction, avoiding the problem of residues being dispersed by water flow and re-attaching in traditional single rinsing methods. This significantly improves the thoroughness of cleaning the inner wall of the dilution cup.
[0009] Furthermore, the liquid addition cleaning device includes a second fixed tube, a second mounting hole is provided on the fixed platform, the second fixed tube is slidably disposed in the second mounting hole, a second liquid addition tube for adding cleaning liquid to the dilution cup is provided in the second fixed tube, a second liquid extraction tube for extracting cleaning liquid from the dilution cup is also provided in the second fixed tube, a second fixed plate is installed on the outer wall of the second fixed tube, a second spring is provided on the second fixed plate, the end of the second spring away from the second fixed plate is fixedly connected to the limiting frame, a second limiting post is provided on the fixed platform, the end of the second limiting post away from the fixed platform passes through the second fixed plate and extends into the central hole of the second spring.
[0010] In this design, the second liquid addition tube and the second liquid extraction tube are coaxially encapsulated within a slidable second fixed tube. The second fixed plate on the outer wall is flexibly connected to the limiting frame via a second spring. The second limiting post penetrates the fixed plate and extends into the center of the spring, forming precise axial guidance and downward pressure buffer. As the L-shaped lifting frame lowers the second fixed tube, the second liquid addition tube first uniformly injects cleaning fluid into the dilution cup for rinsing, while the second liquid extraction tube simultaneously performs suction, achieving a dynamic cycle of simultaneous injection and suction. Fresh cleaning fluid continuously flushes the inner wall, while waste liquid carrying attached proteins and impurities is immediately extracted by the second liquid extraction tube, eliminating intermediate waiting and repeated lifting and lowering, significantly improving cleaning efficiency.
[0011] Furthermore, both of the rinsing devices include a third fixing tube. A third mounting hole is provided on the fixing platform, and the third fixing tube is slidably disposed in the third mounting hole. A third liquid adding tube for adding clean water into the dilution cup is provided in the third fixing tube. A third liquid drawing tube for drawing clean water from the dilution cup is also provided in the third fixing tube. A third fixing plate is installed on the outer wall of the third fixing tube. A third spring is provided on the third fixing plate. The end of the third spring away from the third fixing plate is fixedly connected to the limiting frame. A third limiting post is provided on the fixing platform. The end of the third limiting post away from the fixing platform passes through the third fixing plate and extends into the central hole of the third spring.
[0012] In this design, the third liquid addition tube first injects clean water into the dilution cup at high speed, and the third liquid extraction tube then draws it in, achieving immediate replacement by rinsing and suction simultaneously. Because two rinsing devices work in sequence, the first rinsing device uses clean water to remove most of the residual cleaning liquid, and the second rinsing device rinses again with fresh clean water and immediately drains it, eliminating trace chemical residues and suspended particles. Compared with the traditional single large-volume rinsing or static overflow method, this device completes two rinsings with a small amount of water, saving water while minimizing the concentration of residual ions. Two short processes replace one long process, resulting in a faster cycle time and higher cleanliness. Furthermore, the adaptive stroke of the third spring prevents damage to the dilution cup due to stress.
[0013] Furthermore, the reabsorption device includes a fourth fixed tube, a fourth mounting hole is provided on the fixed platform, the fourth fixed tube is slidably disposed in the fourth mounting hole, a fourth suction tube is provided in the fourth fixed tube for suctioning the residual liquid in the dilution cup, a fourth fixed plate is installed on the outer wall of the fourth fixed tube, a fourth spring is provided on the fourth fixed plate, the end of the fourth spring away from the fourth fixed plate is fixedly connected to the limiting frame, a fourth limiting post is provided on the fixed platform, the end of the fourth limiting post away from the fixed platform passes through the fourth fixed plate and extends into the central hole of the fourth spring.
[0014] In this solution, after completing the liquid addition cleaning and two rinsing steps, a small amount of liquid film will usually remain on the inner wall of the dilution cup. The liquid at the bottom of the dilution cup is then drawn through the fourth liquid extraction tube. At the same time, the fourth liquid extraction tube of this device can be accurately lowered to the bottom of the dilution cup to quickly extract the liquid remaining after the previous cleaning.
[0015] The working principle and beneficial effects of this solution are as follows: When cleaning the dilution cup begins, the dilution cup rotating disc moves the cup to be cleaned to below the second liquid inlet tube. The L-shaped lifting frame lowers the liquid inlet cleaning device. The second liquid inlet tube injects cleaning fluid for initial rinsing, and then the cup is extracted by the second liquid extraction tube. The second spring buffer prevents excessive insertion and damage to the dilution cup. Subsequently, the dilution cup moves to below the first rinsing device. The third liquid inlet tube injects clean water for rinsing, and the cup is extracted by the third liquid extraction tube. After two identical rinsings, the cleanliness is further improved. Then, the dilution cup moves to below the re-absorption device, and the fourth liquid extraction tube deeply dries the residual liquid. Finally, the dilution cup reaches the position of the inner wall scraping and suction device. The first liquid extraction tube brings the wall scraper into the dilution cup. The outer diameter of the wall scraper is adapted to the inner diameter of the dilution cup, sliding to scrape off the residue on the inner wall and push it to the bottom. At the same time, the first liquid extraction tube extracts the residue simultaneously. The entire cleaning process, through a composite process of liquid inlet cleaning, double rinsing, deep drying, and wall scraping and suction, combined with the spring limit protection mechanism of each component, achieves thorough cleaning of the inner wall of the dilution cup, solving the technical problem of incomplete cleaning of the inner wall of the dilution cup in existing dilution cup cleaning devices.

[0023] like Figure 2 and Figure 3 As shown, both rinsing devices include a third fixed tube 22, a third liquid adding tube 23, a third liquid drawing tube 24, a third fixed plate 25, a third spring 26, and a third limiting post 27.

A radial clearance fit is formed between the inner wall of the third spring 26 and the outer surface of the third limiting post 27. When the third spring 26 is compressed, it moves axially along the third limiting post 27.
[0024] like Figure 2 and Figure 3 As shown, the reabsorption mechanism includes a fourth fixed tube 30, a fourth suction tube 31, a fourth fixed plate 32, a fourth spring 33, and a fourth limiting post 34. A fourth mounting hole 35 is provided on the fixed platform 4, penetrating the upper and lower end faces of the fixed platform 4. A slidable fourth fixed tube 30 is installed inside the fourth mounting hole 35. The fourth suction tube 31 is fixedly connected inside the fourth fixed tube 30 and is used to aspirate residual liquid from the dilution cup. A fourth fixed plate 32 is installed through the outer wall of the fourth fixed tube 30, and the fourth fixed tube 30 is fixedly connected to the fourth fixed plate 32. A fourth fixed plate 32 is provided on the fourth fixed plate 32. A fourth sliding hole 36 is provided.

When the fourth spring 33 is compressed, it moves axially along the fourth limiting post 34.
[0025] In practice When the fully automated specific protein analyzer body 1 performs dilution cup cleaning, the dilution cup is first rotated by the dilution cup rotating disk 2 to below the second liquid addition tube 15. At this time, the L-shaped lifting frame 3 moves the fixed platform 4 closer to the dilution cup. As the L-shaped lifting frame 3 begins to move downward, it simultaneously moves the fixed platform 4. As the fixed platform 4 moves, it simultaneously moves the second liquid addition tube 15 and the second liquid extraction tube 16 inside the second fixed tube 14 into the dilution cup. As the second liquid addition tube 15 and the second liquid extraction tube 16 enter the dilution cup and contact the bottom wall of the dilution cup, they move the second fixed tube 14 within the second mounting hole 20 on the fixed platform 4. As the second fixed tube 14 moves upward, it simultaneously moves the second fixed plate 17 through the second sliding hole 20. The moving hole 21 moves axially along the second limiting post 19. During the movement, the second fixed plate 17 compresses the second spring 18 sleeved outside the second limiting post 19. The upper end of the second spring 18 is fixed by the limiting frame 5. The compression of the second spring 18 effectively prevents the L-shaped lifting frame 3 from driving the second liquid adding pipe 15 and the second liquid drawing pipe 16 to insert into the dilution cup due to excessive displacement and damage to the dilution cup. After the second liquid adding pipe 15 and the second liquid drawing pipe 16 enter the dilution cup, the second liquid adding pipe 15 injects the cleaning solution into the dilution cup. The cleaning solution performs a preliminary rinsing of the dilution cup. Then the second liquid drawing pipe 16 draws out the cleaning solution from the dilution cup. After the second liquid drawing pipe 16 completes the extraction process, the L-shaped lifting frame 3 drives the second fixed pipe 14 to rise as a whole, taking the second liquid adding pipe 15 and the second liquid drawing pipe 16 away from the dilution cup. At this time, the dilution cup is in a state of residual cleaning solution.
[0026] After the dilution cup undergoes initial cleaning via the second liquid addition pipe 15, the dilution cup rotating disc 2 moves the dilution cup by one position. At this point, the dilution cup containing residual cleaning fluid is positioned below the third liquid addition pipe 23 on the third fixed pipe 22. The L-shaped lifting frame 3 lowers the third fixed pipe 22 on the fixed platform 4. During the descent of the third fixed pipe 22, the third liquid addition pipe 23 and the third liquid extraction pipe 24 simultaneously descend into the dilution cup containing residual cleaning fluid. At this point, the third liquid addition pipe 23 rinses the dilution cup with clean water, and then the third liquid extraction pipe 24 extracts the clean water from the dilution cup. During the descent of the third liquid addition pipe 23 and the third liquid extraction pipe 24 into the dilution cup, the third fixed pipe 23, located outside the third liquid addition pipe 23 and the third liquid extraction pipe 24, remains in place. 2. It can slide within the third mounting hole 28. When the third fixing tube 22 moves, it drives the third fixing plate 25 to slide along the third sliding hole 29 on the third limiting post 27. During the sliding process, the third fixing plate 25 gradually compresses the third spring 26 located below the limiting frame 5. The compression of the third spring 26 prevents damage to the dilution cup due to excessive displacement of the third liquid adding tube 23 and the third liquid drawing tube 24. Since there are two rinsing devices, after the dilution cup with residual cleaning liquid is rinsed by the first rinsing device, the L-shaped lifting frame 3 drives the fixing platform 4 to move upward. At this time, the dilution cup rotating disk 2 drives the dilution cup to rotate one dilution cup position. At this time, the dilution cup is below the second rinsing device. The L-shaped lifting frame 3 rinses the dilution cup twice through the second rinsing device to improve the cleaning degree.
[0027] After the dilution cup containing residual cleaning fluid is rinsed twice by the two rinsing devices, the dilution cup rotating disc 2 moves the dilution cup to the next position. At this point, the dilution cup is located below the fourth fixed tube 30. The L-shaped lifting frame 3 lowers the fourth suction tube 31 inside the fourth fixed tube 30 into the dilution cup. The fourth suction tube 31 further dries the residual liquid in the dilution cup. During its descent, the fourth suction tube 31 slides through the fourth fixed tube 30 within the fourth mounting hole 35. As the fourth fixed tube 30 slides, it moves the fourth fixed plate 32 upwards. The fourth fixed plate 32 moves axially along the fourth limiting post 34 through the fourth sliding hole 36. During the sliding process, the fourth fixed plate 32 gradually compresses the fourth spring 33 located below the limiting frame 5. The compression of the fourth spring 33 prevents damage to the dilution cup due to excessive displacement of the fourth suction tube 31. After the residual liquid in the dilution cup is further drained through the fourth suction tube 31, the L-shaped lifting frame 3 drives the fourth suction tube 31 to move out of the dilution cup. At this time, the dilution cup rotating disk 2 drives the dilution cup to move one dilution cup position, bringing the dilution cup below the first suction tube 7.
[0028] After the dilution cup rotating disc 2 moves the dilution cup below the first suction tube 7, the L-shaped lifting frame 3 moves the first suction tube 7 inside the first fixed tube 6 into the dilution cup. Since a scraper block 11 is installed below the first suction tube 7, as the first suction tube 7 is moved into the dilution cup, the scraper block 11 simultaneously enters the dilution cup. The outer diameter of the scraper block 11 matches the inner diameter of the dilution cup. During the movement, the scraper block 11 slides against the inner wall of the dilution cup, thoroughly scraping away any remaining liquid or sticky residue. Because this process is achieved by the L-shaped lifting frame 3 gradually lowering the cup, the residual liquid or residue scraped away by the scraper block 11 is pushed to the bottom of the dilution cup. Since the bottom of the first suction tube 7 is lower than the lower end face of the scraper block 11, the first suction tube 7 will approach the bottom of the dilution cup before the scraper block 11 during its descent. The first suction tube 7 will extract the residual liquid and residue pushed to the bottom of the dilution cup by the scraper block 11, thereby achieving the purpose of thoroughly cleaning the inner wall of the dilution cup. When the scraper block 11 encounters resistance during its descent, it will gradually drive the first fixing tube 6 to slide on the first mounting hole 12. When the first fixing tube 6 slides, it will simultaneously drive the first fixing plate 8 to slide on the first limiting post 10 through the first sliding hole 13. When the first fixing plate 8 moves with the first fixing tube 6, it will simultaneously compress the first spring 9. By compressing the first spring 9, the problem of damage to the dilution cup due to excessive displacement of the first suction tube 7 or the scraper block 11 is prevented.
