Description

Technical Field

[0001] This utility model relates to the field of eye drop production technology, and in particular to a sterile preparation and filtration device for eye drops. Background Technology

[0002] Eye drops are one of the most commonly used medications in ophthalmology, offering direct and quick treatment for many eye conditions. With changing lifestyles and working conditions, people are spending more and more time using their eyes, such as prolonged computer use, watching television, and playing video games, easily leading to visual fatigue and dry eye syndrome. Both of these conditions can be temporarily relieved or soothed by eye drops.

[0003] Patent publication number CN214437146U discloses a solution preparation device for eye drop production, including an outer barrel and an inner barrel installed inside the outer barrel. Both the outer and inner barrels have inlets at their tops. A drive motor is fixedly connected to the top of the inner barrel, and a slag discharge mechanism is installed inside the inner barrel. The slag discharge mechanism includes a frame, and a lifting block is slidably connected inside the frame. Multiple connecting rods are fixedly connected around the lifting block. This invention uses an air pump to inflate a telescopic air bladder through an air pipe. The inflated air bladder pushes the lifting block upwards, causing the elastic filter screen to move upwards, separating the waste residue from the clear liquid. The waste residue is then lifted upwards to the upper part of the inner barrel, where it can be removed through the inlet. Overall, this invention effectively improves the ease of cleaning.

[0004] The patent describes a method of cleaning waste residue from an elastic filter by raising it to the feed inlet. However, the limited operating space at the feed inlet makes it difficult to thoroughly clean the waste residue from the elastic filter, resulting in dead zones. Utility Model Content

The inner barrel 9 is rotatably connected to the outer barrel 2. The inner wall of the inner barrel 9 is provided with multiple small holes. The bottom wall of the inner barrel 9 is vertically fixed with a cylinder 11. A driving component is provided inside the cylinder 11. The end of the driving component is connected to a filter. The bottom surface of the outer barrel 2 is symmetrically provided with two drain valves 13. A waterproof cover 14 is fixedly connected to the center of the bottom wall of the outer barrel 2.

[0026] The driving component includes a lead screw motor 32 fixedly connected inside the cylinder 11. The output end of the lead screw motor 32 is connected to a screw 28. The outer edge of the screw 28 is threaded with an internal thread tube 27. The internal thread tube 27 is slidably connected inside the cylinder 11. Two guide grooves 29 are symmetrically opened on the inner wall of the cylinder 11. A guide block 35 is slidably connected in each guide groove 29. The guide block 35 is fixed to the outside of the internal thread tube 27. The top surface of the internal thread tube 27 is fixedly connected to a top plate 31. Multiple arrayed L-shaped support rods 10 are fixedly connected to the side of the top plate 31. The filter element is fixedly connected to the multiple L-shaped support rods 10.

[0027] The filter element includes a filter screen 33 fixedly connected to the ends of multiple L-shaped support rods 10. The filter screen 33 is slidably sleeved on the outer edge of the cylinder 11. An outer ring 34 is fixedly sleeved on the outer edge of the filter screen 33. The outer ring 34 is attached to the inner wall of the inner barrel 9. The top surface of the outer ring 34 is provided with a trapezoidal groove 36. The bottom surface of the trapezoidal groove 36 has multiple leakage holes.

[0028] The limiting component includes two symmetrically fixed support blocks 4 on the outside of the cover plate 5. The bottom surface of the support block 4 is provided with a second threaded groove 25. The inner thread of the second threaded groove 25 is connected to an external threaded block 24. The top surface of the external threaded block 24 is fixedly connected to a connecting rod 26. The connecting rod 26 movably passes through the second threaded groove 25. The top surface of the connecting rod 26 is fixedly connected to a rotating block 7. Each of the two external threaded blocks 24 is provided with a support plate 3. The support plate 3 is fixedly connected to the outer barrel 2. The top surface of the two support plates 3 is provided with a first threaded groove 23. The outside of the outer barrel 2 is fixedly connected to a fixing plate 16. The top surface of the fixing plate 16 is vertically fixed to a guide rod 20. The outer edge of the guide rod 20 is slidably sleeved with a guide sleeve 17. The top surface of the guide rod 20 is fixedly connected to a limiting block 19. The limiting block 19 and the guide sleeve 17 abut against a spring 18. The spring 18 is sleeved on the outer edge of the guide rod 20.

[0029] By connecting the cover plate 5 to the outer barrel 2 using a limiting component, and installing the filter element on the outside of the cylinder 11 using a driving component, it is easy to open the cover plate 5 and remove the filter element from the inner barrel 9 for cleaning. This increases the operating space for cleaning the filter element, allowing for more thorough cleaning and avoiding cleaning dead spots on the filter element.

[0030] Working principle: During use, the raw material is fed into the inner barrel 9 through the feed pipe 8. Then, the drive motor 15 drives the drive shaft 12 to rotate, which in turn drives the inner barrel 9 to rotate. The rotation of the inner barrel 9 centrifuges the raw material. After processing, the waste residue remains on the filter screen 33. Then, the two rotating blocks 7 are rotated, which drives the external threaded block 24 to rotate, so that the external threaded block 24 is screwed from the first threaded groove 23 into the second threaded groove 25. Then, the cover plate 5 is pulled upward by the handle 6. The cover plate 5 drives the guide sleeve 17 to the outer edge of the guide rod 20. The guide sleeve 17 compresses the spring 18, causing the cover plate 5 to separate from the top surface of the outer barrel 2. Then, the cover plate 5 is rotated around the center of the guide rod 20, causing it to deviate from the top surface of the outer barrel 2. The screw motor 32 then drives the screw 28 to rotate. As the screw 28 rotates, it drives the internal threaded tube 27 to rise within the cylinder 11. The internal threaded tube 27 drives the L-shaped support rod 10 to rise, which in turn drives the filter screen 33 and the outer ring 34 to rise. As the outer ring 34 rises, it passes through the sharp edge of the trapezoidal groove 36. The waste residue adhering to the inner wall of the inner barrel 9 is scraped into the trapezoidal groove 36 until the internal threaded tube 27 separates from the screw 28. Then, the filter screen 33, together with the outer ring 34, is removed from the inner barrel 9. The waste residue in the filter screen 33 and the outer ring 34 is then cleaned. After cleaning, the internal threaded tube 27 is connected to the outer edge of the screw 28, and the guide block 35 is inserted into the guide groove 29 on the inner wall of the cylinder 11. Then, the screw motor 32 rotates in the opposite direction, causing the internal threaded tube 27 to descend into the cylinder 11, allowing the filter screen 33 to return to the inner barrel 9. The bottom wall is then pulled upward by the handle 6, and the cover plate 5 is pulled upward by the handle 6. The cover plate 5 drives the guide sleeve 17 to move upward on the outer edge of the guide rod 20. The guide sleeve 17 drives the spring 18 to compress. Then the cover plate 5 is rotated to the top of the outer barrel 2. Then the handle 6 is released and the spring 18 is reset, so that the cover plate 5 abuts against the top surface of the outer barrel 2. At the same time, the sealing ring 22 on the bottom surface of the cover plate 5 is engaged in the sealing groove 21 on the top surface of the inner barrel 9. Then the two external threaded blocks 24 are screwed from the second threaded groove 25 into the first threaded groove 23 by the screw block 7 to fix the cover plate 5 and the outer barrel 2.
