Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a precision filter element. Background Art

[0002] The precision filter element is the heart of the filter. As the name implies, it is a filter element. The main function of the filter element is also the main principle of the filter, which is to purify the original ecological resources and reuse the resources. The purification equipment required is generally used in the filtration industry such as oil filtration, water filtration, and air filtration. Removing a small amount of impurities in the filter medium can protect the normal operation of the equipment or the cleanliness of the air. When the fluid passes through the filter element with a certain precision in the filter, its impurities are blocked, and the clean fluid flows out through the filter element.

[0003] The existing filter is usually composed of a protective shell and a filter element, and the filter element is usually arranged inside the protective shell. When filtering water, the water flows into the protective shell and contacts the filter element, and then is discharged from the protective shell to achieve water filtration;

[0004] Since the water flow directly impacts the surface of the filter element, long-term water flow impact will cause the filter material in the filter element to expand and deform, thereby affecting its pore structure. After the filter material is deformed, the change in pores may lead to a reduction in the filtration effect, causing the water purification capacity of the water purifier to decrease.

[0005] In view of this, this application is hereby filed. Utility Model Content
