Description

Technical Field

[0001] The utility model relates to the technical field of independent ventilation cages, in particular to a blocking type filtering independent ventilation cage. Background Art

[0002] The blocking filter independent ventilation cage is a device used for experimental animal breeding, usually for rodents or other small experimental animals. The blocking filter independent ventilation cage usually has an independent ventilation system, so that each cage can control ventilation individually, which can prevent cross contamination and disease transmission and maintain the health of experimental animals.

[0003] Cages are usually physically isolated to block air flow to ensure that the ventilation environment of each cage is independent of other cages, which helps prevent cross-contamination and maintain the health of experimental animals. However, when the cage box of the existing blocking filter independent ventilation cage on the market is taken out, the air outlet of the ventilation pipe and the air inlet of the cage box will not automatically close, so external dust or bacteria may still enter the ventilation pipe or cage box.

A rotating mechanism is provided between the fixed joint 6 and the outer sleeve 5, and the rotating mechanism includes a guide rod 9, which is fixedly installed on both sides of the inner wall of the port of the outer sleeve 5 and the movable joint 7. The outer walls of the movable joint 7 and the inner sleeve 13 are provided with guide grooves 10 movably connected to the guide rod 9. The rotating mechanism also includes a ventilation plate 11, which is provided at the inner wall of the fixed joint 6 and the outer sleeve 5, and a blocking plate 12 is provided at one end of the movable joint 7 and the inner sleeve 13 close to the ventilation plate 11;

[0025] In this embodiment, when placing the cage box body 4, the outer sleeve 5 at one end of the cage box body 4 is inserted into the outside of the movable joint 7. When inserting, the guide rod 9 on one side of the outer sleeve 5 slides into the guide groove 10 on the outer wall of the movable joint 7, and at the same time, the guide rod 9 at the inner wall of the movable joint 7 will slide into the guide groove 10 at the outer wall of the inner sleeve 13 at the same time, so that the movable joint 7 and the inner sleeve 13 will be driven to rotate at the same time. When the movable joint 7 and the inner sleeve 13 rotate, the blocking plate 12 is controlled to rotate synchronously, and then the passages of the two ventilation plates 11 are opened, so that the gas in the ventilation pipe 3 can smoothly enter the cage box body 4. On the contrary, when the cage box body 4 is taken out, the two blocking plates 12 rotate and block the ventilation plate 11, so that the air outlet of the ventilation pipe 3 and the air inlet of the cage box body 4 are automatically closed, which can prevent dust or bacteria from entering.

[0028] Working principle: when placing the cage box body 4, the outer sleeve 5 at one end of the cage box body 4 is inserted into the outside of the movable joint 7. When inserting, the guide rod 9 on one side of the outer sleeve 5 slides into the guide groove 10 on the outer wall of the movable joint 7, and at the same time, the guide rod 9 at the inner wall of the movable joint 7 will slide into the guide groove 10 at the outer wall of the inner sleeve 13 at the same time, so that the movable joint 7 and the inner sleeve 13 will be driven to rotate at the same time. When the movable joint 7 and the inner sleeve 13 rotate, the blocking plate 12 is controlled to rotate synchronously, and then the passages of the two ventilation plates 11 are opened, so that the gas in the ventilation pipe 3 can smoothly enter the cage box body 4. Conversely, when the cage box body 4 is taken out, the two blocking plates 12 rotate and block the ventilation plate 11, so that the air outlet of the ventilation pipe 3 and the air inlet of the cage box body 4 are automatically closed.
