Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary medical related equipment, in particular to a refrigerant cleaning module. Background Art

[0002] The refrigerant cleaning module is a maintenance tool for automobile air-conditioning systems. It is mainly used to clean the refrigerant in the air-conditioning system. The refrigerant is circulated in the air-conditioning system and will gradually become ineffective due to the accumulation of dust, dirt, oil stains and microbial contamination, affecting the performance and efficiency of the air-conditioning system. Therefore, regular cleaning of the refrigerant is an important measure to keep the air-conditioning system in good operating condition. The refrigerant cleaning module uses a filter to filter out particulate matter and oil stains in the refrigerant.

[0039] When it is necessary to filter the refrigerant, first rotate the second locking block 62 so that the second locking block 62 is engaged with the locking groove 14, and the position of the first rotating shaft 5 is locked. Then, the refrigerant flowing in from the feed pipe 2 is filtered through the multiple first filter screens 7 close to the side of the feed pipe 2 in turn (because the first filter screen 7 close to the side of the feed pipe 2 is attached to the inner wall of the box body 1, the refrigerant can only be filtered through the first filter screen 7), and then filtered through the multiple second filter screens 17 close to the side of the discharge pipe 3, and finally flows out from the discharge pipe 3. After a period of time, the second locking block 62 can be rotated to separate the second locking block 62 from the locking groove 14, and then the first rotating shaft 5 is rotated to remove the second locking block 62 from the locking groove 14. The first rotating shaft 5 is rotated 180°, and the second rotating shaft 16 is also rotated 180°, so that the first filter screen 7 located on the side close to the feed pipe 2 and the second filter screen 17 located on the side close to the discharge pipe 3 are changed, and then the second locking block 62 is rotated to make the second locking block 62 engage in the locking groove 14 to fix the position of the first rotating shaft 5 and the second rotating shaft 16, thereby realizing the adjustment of the position between the multiple first filter screens 7 and the multiple second filter screens 17, so as to achieve the purpose of greatly reducing the frequency of replacing or cleaning the first filter screen 7 on the first rotating shaft 5; by setting multiple first filter screens 7 and second filter screens 17, the filtering effect of impurities in the refrigerant can be ensured.

[0040] By setting the first plate body 41, the second plate body 42 and the third plate body 43, when the first filter screen 7 and the second filter screen 17 need to be replaced or cleaned, it is only necessary to rotate the first plate body 41 and the second plate body 42 so that the first plate body 41 and the second plate body 42 are separated from the inner wall of the box body 1, and then the cover plate 4 can be removed, and then the first rotating shaft 5 or the second rotating shaft 16 can be removed to replace or clean the first filter screen 7 and the second filter screen 17. The operation is simple and convenient.

[0041] By providing the first rotating wheel 18, the second rotating wheel 19 and the synchronous belt 20, the first rotating shaft 5 and the second rotating shaft 16 can only move synchronously. Therefore, when the position of the first rotating shaft 5 is locked, the second rotating shaft 16 cannot rotate either. When the position of the first filter screen 7 is changed, the position of the second filter screen 17 is also adjusted synchronously, making the operation simpler and more convenient.

[0042] By providing the first connecting block 10, the first connecting groove 9, etc., the first rotating shaft 5 and the second rotating shaft 16 are respectively connected to the box body 1 and the cover plate 4 in a detachable manner, which has a simple structure and is easy to operate.

[0043] By providing the first limiting block 26 , the second limiting block 27 and the like, the first plate body 41 and the second plate body 42 are limited, thereby ensuring the connection between the first plate body 41 and the second plate body 42 and the box body 1 .

[0044] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
