Description

Technical Field

[0002] Combined ultrafiltration water purification filter element is a multifunctional filtering device, which is usually used in water treatment and purification to improve water quality. This filter element integrates multiple filtering technologies and can effectively remove impurities, harmful substances and microorganisms in water to provide clean and safe drinking water. The advantage of combined ultrafiltration water purification filter element lies in its comprehensive filtering performance. It can flexibly configure the filtering level and materials according to different water quality conditions to meet the needs of different users.

[0003] However, when multiple filter elements are combined together, the replacement efficiency of the filter elements needs to be considered. Usually, the filter element is directly inserted into the interior of the filter, and the cover plate is used to limit the position. However, during actual filtration, the filtered sewage may cause the position of the filter element to shift, thereby causing the filter element to loosen and create gaps, and the sewage flows out through the gaps. In addition, the buckle fixing method is usually simple and can only operate a single filter element, and different filter elements cannot be freely selected for simultaneous fixing operations. For this reason, a combined ultrafiltration water purification filter element is needed to solve the existing deficiencies. Utility Model Content
