AI Technical Summary
Existing pleated water filter cartridges are prone to deformation under high water pressure, resulting in poor filtration performance.
The filter element features a deformation-resistant structure, including a support plate and a reinforcing rod. The support plate fits snugly against the inner wall of the filter element and is connected to the threaded cap via the reinforcing rod, forming a stable vertical positioning that increases the filter element's compressive strength. The support plate also scrapes away impurities from the inner wall of the filter element when the threaded cap is unscrewed.
It effectively prevents the filter element from deforming under high water pressure, maintains good filtration shape and performance, and achieves efficient cleaning and removal of impurities.
