The outer wall of the bottom end of the connecting block 5 is elastically connected to the limiting plate 9 through a spring 11. The setting of the limiting plate 9 is to facilitate the movement of the card plate 8. The limiting plate 9 moves downward, stretching the spring 11 to release the limiting plate 9. The elastic force of the spring 11 drives the limiting plate 9 back to its original position. The limiting plate 9 is arranged in an arc shape. The width of the limiting plate 9 is greater than the width of the outer wall of the bottom end of the card plate 8. One end of the spring 11 is fixedly connected to the connecting pipe 6.

The inclined surface of the card plate 8 is squeezed by the outer wall of the flange of the connecting pipe 6 and moves away from the center direction of the connecting block 5. After the flange of the connecting pipe 6 moves into the connecting block 5, the card plate 8 pops out and is connected to the front end outer wall of the flange of the connecting pipe 6, realizing the quick connection of the connecting pipe 6 and the liquid inlet pipe 4. The front end outer wall of the card plate 8 is arranged in an inclined shape, and the outer wall of the card plate 8 is slidably connected to the inner wall of the connecting block 5.

[0034] Reference Figure 4-Figure 6The filter assembly includes a slider 13. The setting of the slider 13 limits the moving direction of the filter basket 12 in the cylinder 1. The slider 13 provides support for the sliding of the lifting rod 14. A sliding groove is provided on the inner wall of the right end of the slider 13. A through hole with the same diameter as the left end of the embedded rod 16 is provided in the sliding groove on the inner wall of the slider 13.

[0035] Working principle: By moving the front end of the basket filter toward the flange of the connecting pipe 6, the rear end of the flange of the connecting pipe 6 squeezes the front end inclined surface of the card plate 8, causing the card plate 8 to move away from the center direction of the connecting block 5. When the flange of the connecting pipe 6 is completely moved into the inner wall of the connecting block 5, the card plate 8 pops out toward the center direction of the connecting block 5 and is clamped on the front end outer wall of the flange of the connecting pipe 6. The limiting column 10 passes through the flange through-hole of the connecting pipe 6, so that the liquid inlet pipe 4 and the connecting pipe 6 are quickly installed. The liquid enters the cylinder body 1 through the connecting pipe 6 and is filtered by the filter basket 12 and discharged from the liquid outlet pipe 2. When the filter basket 12 needs to be disassembled, the cylinder cover 3 is removed from the upper end of the cylinder body 1, and the embedded rod 16 is moved to the right to squeeze the spring 2 15, so that the outer wall of the left end of the embedded rod 16 leaves the upper inner wall of the cylinder body 1, and the lifting rod 14 can be pulled upward to drive the filter basket 12 to move upward and move it out of the cylinder body 1.
