Description

Exempt from to tear open water filter

Technical Field

The utility model relates to a water filter, in particular to a disassembly-free water filter.

Background

In the circulating water system of a modern air conditioning system, a water filter plays a vital role, and is mainly used for filtering impurities in circulation, so that the normal operation of the system is ensured. Conventional water filters are generally designed to be fixed at a certain location of an air conditioning system to remove impurities from circulating water. However, these filters face a major problem: in the long-time use process, the filter screen is easy to block, so that the refrigerating effect of the air conditioning system is affected, and meanwhile, after the filter screen is blocked, the cleaning and maintenance processes are quite tedious and difficult.

In particular, for the DN20 specification water filter installed inside the ceiling, the design disadvantage is more prominent, as shown in fig. 1 and 2, on one hand, the filter screen is easy to be blocked due to the excessively small volume of the filter section (the effective volume is only 21mm by 37 mm); on the other hand, when cleaning or maintenance is required, due to the lack of a structural design convenient for operation, the filter plug 12 must be disassembled to clean, which not only increases the working difficulty, but also easily causes a large amount of circulating water of the air conditioner to flow out when disassembling due to the fact that no proper valve can be closed, thereby increasing the difficulty of cleaning work, especially when operating in a ceiling with a narrow space.

As shown in fig. 3, the stainless steel filter screen is easy to be blocked in the using process, so that the water flow is reduced, and the refrigerating effect of the air conditioner is affected. The DN20 filter that uses is installed in the smallpox is inside, when dismantling this end cap, because there is not the valve to close, leads to when dismantling, has more air conditioner water to flow in the pipeline inside, increases the degree of difficulty for the cleaning (because most smallness of smallpox inner space).
