The limiting card plate 561 is arranged in the limiting groove 532 and cooperates with the limiting block 533. When the pressing component 55 drives the sliding inclined sliding block 531 to slide, the sliding displacement distance of the sliding block 53 is limited by the limiting card plate 561 to prevent the sliding block 53 from getting stuck, which is conducive to the smooth sliding of the sliding block 53.

[0020] In this embodiment, the pressing assembly 55 includes a pressing shell 541, a pressing cavity is provided in the pressing shell 541, a sleeve 542 is provided at the bottom of the pressing shell 541 corresponding to the two inclined sliders 531, the sleeve 542 is communicated with the pressing cavity, two pressing holes 543 are opened in the pressing cavity, a pressing switch 544 is installed in the pressing cavity, and two pressing columns 545 and two pressing teeth 546 are provided at the bottom of the pressing switch 544 to abut against the two inclined sliders 531, and the two pressing columns 545 are respectively inserted into the two Inside the sleeve 542, two pressing teeth 546 are respectively inserted into the two pressing holes 543, and the two pressing columns 545 are sleeved with pressing springs 547. When the pressing switch 544 is pressed down, the two pressing columns 545 push the two inclined sliding blocks 531 to move obliquely, and at the same time make the sliding block 53 move laterally. The two pressing teeth 546 are plugged into the two pressing holes 543, and when the pressing switch 544 moves up and down, it can play the role of a guide column, so that the two pressing columns 545 can accurately contact the two inclined sliding blocks 531.

[0021] In this embodiment, the connecting cover 52 includes a lower cover ring 522 which is connected to the connecting ring 51 and an upper cover ring 521 which is connected to the pressing shell 541. The inner wall of the lower cover ring 522 is provided with a lower cover clamping protrusion 523, and the lower cover ring 522 is provided with an outer sliding hole 524 corresponding to the inner sliding hole 57. The outer wall of the connecting ring 51 is provided with a lower cover clamping groove, and the lower cover clamping groove is provided with a lower cover clamping block 525 which is engaged with the lower cover clamping protrusion 523 to facilitate the clamping of the connecting cover 52 with the upper part of the filter cartridge 41. The inner wall of the upper cover ring 521 is provided with an upper cover clamping hole 526, and the outer wall of the pressing shell 541 is provided with an upper cover clamping block 527 which is engaged with the upper cover clamping hole 526 to facilitate the clamping of the pressing shell 541 with the upper part of the connecting cover 52.
