Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a filter element installation structure for a water purifier. Background Art

[0002] The filter element is one of the core components of a water purifier. Currently, most ultrafiltration water purifiers usually use PP cotton filter elements, pre-activated carbon filter elements, reverse osmosis membrane filter elements and post-activated carbon filter elements in series to deeply purify water.

[0003] Since the filter elements are mostly designed to be cylindrical, in order to facilitate the positioning and installation of the filter elements, current water purifiers often use C-type clamps to position the filter elements. The inner diameter of the C-type clamp is compatible with the outer diameter of the filter element, and the opening size of the C-type clamp is slightly smaller than the outer diameter of the filter element, so that the filter element can be held. Retaining rings are provided on the upper and lower sides of each C-type clamp on the outer wall of the filter element to prevent the filter element from moving inside the C-type clamp.

[0004] Although the method of using a C-type clamp to position and install the filter element is simple and easy to operate, the C-type clamp will be deformed during the process of disassembling and installing the filter element. After multiple disassembly and installation, the filter element may not be clamped due to wear or material fatigue of the C-type clamp. During disassembly and installation, if the force is applied in the wrong direction, the C-type clamp may easily break, which needs to be improved. Utility Model Content
