Detailed ways

In order to make it easy to understand the technical means, creation features, achieved goals and effects of the present invention, the present invention will be further described below with reference to the specific figures.

Embodiment 1: Referring to a filter element assembly shown in Figure 1-Figure 7 that is easy to disassemble and assemble, it includes a sliding cylinder 1, a filter element 2, a rotating disk 3, a pressing block 5 and a waterway plate 6,

The inner ring of the pressing block 5 is movably sleeved with a rotating disk 3 that can rotate relative to it. The rotating disk 3 is press-fitted on the waterway plate 6 through the pressing block 5, and the outside of the filter element 2 is sleeved with a sliding cylinder 1;

The outer circumference of the lower end of the sliding cylinder 1 and the outer circumference of the upper end of the rotating disk 3 are respectively provided with a number of wedge blocks 11 and wedge block grooves 31 which are used in cooperation with each other, and the surfaces of the wedge blocks 11 and the wedge block grooves 31 abut against each other. A first guide inclined surface 110 and a second guide inclined surface 310 are respectively arranged on the upper end of the rotating disk 3 to drive the rotating disk 3 to rotate relative to the pressing block 5. At the same time, a collar 32 protrudes inward from the inner wall of the upper end of the rotating disk 3. A plurality of card slots 320 are evenly arranged on the clip ring 32;

The outer circumference of one end of the filter element 2 inserted into the rotating disk 3 is evenly provided with a plurality of buckles 21 , and the surface of the buckles 21 in contact with the card slot 320 is provided with a surface that can cooperate with the card slot 320 to drive the The third guiding inclined surface 210 of the rotating disk 3 rotating relative to the pressing block 5,

The pressing block 5 is also provided with a reset device for driving the rotary disk 3 to rotate and reset relative to the pressing block 5 .

In this embodiment, as shown in Figures 3 and 4, there are two reset devices. The two reset devices are arranged in opposite tangential directions along the radial ends of the rotary disk 3. The reset device includes a spring 4 and a screw 7. One end is mounted on the rotary disk 3 by screws 7 , and the other end is mounted on the pressing block 5 by screws 7 .
