Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a filter element assembly which is convenient for quick disassembly and assembly. Background Art

[0002] The simple operation of water purification equipment has become the main research topic at present. As the main component of water purification equipment, the installation method of the filter element is also relatively important.

[0003] In the prior art, the filtering device of water purification equipment generally includes a filter element, a filter housing and a filter cover. The assembly method is as follows: put the filter element into the filter housing, then align the lower end face of the filter element with a circle of flanges originally designed on the filter housing, then hold the filter housing and the filter element steadily horizontally and slowly move them into the filter cover. At the same time, it is also necessary to ensure that the upper end face of the filter element is aligned with a circle of flanges provided on the filter cover, and then carefully pre-lock it horizontally. Then, a special wrench is sleeved from the lower end of the filter housing and rotated to lock it.

[0004] However, the above-mentioned prior filtering device has the following deficiencies in the assembly process: on the one hand, it is necessary to align the filter element with the flange at the bottom of the filter housing, and at the same time, align the upper end face of the filter element with the flange of the filter cover, and also align the upper end of the filter housing with the filter cover. Moreover, it is necessary to ensure that the filter element is vertically erected in the exact middle of the filter housing without deviation. The alignment is difficult to achieve, the operation is cumbersome and time-consuming. When locking the filter housing and the filter element, it is also necessary to use a special wrench, which requires a lot of strength and is also troublesome. On the other hand, between the filter element and the filter housing and between the filter element and the filter cover, the sealing effect is achieved by the filter element itself squeezing against the flange. This method is very difficult to ensure no leakage and affects the sealing effect of the installation. Summary of the Utility Model
