Description

Technical Field

[0001] The utility model relates to the field of water filters, and more specifically, it relates to a water filter. Background Art

[0002] Water filters are very common in industrial production. In industrial production, pure water is often required for industrial production. Therefore, water filters are needed to filter water. Existing water filters generally filter the water introduced into the water filter through filter elements. Various filter materials for water filtration are placed in the filter elements. After the filter element is replaced, the entire structure of the filter element will be discarded, thus increasing the usage cost of the water filter. It is also inconvenient to replace different filter materials according to different water purification requirements, affecting the use of the water filter. During the use of existing water filters, filtered debris will adhere to both the inner wall of the filter element and the inner wall of the housing. After the filter element is replaced, the debris adhering to the inner wall of the housing needs to be cleaned separately, thus increasing the time for maintaining and servicing the water filter. While it is inconvenient to maintain and service the water filter, it also affects the use of the water filter. Summary of the Utility Model
