By providing the top cover 3 at the top of the filter cartridge 2 and cooperating with the jacks 4, the limit rings 6 and the locking components 7, it plays a role in quickly positioning the filter element 1, making the disassembly and assembly of the filter element 1 fast and simple. Users can easily complete the replacement or cleaning of the filter element 1 without complex tools or cumbersome steps. Users can regularly maintain the filter element 1 to ensure its filtering effect and service life, thereby improving the operation efficiency and stability of the entire device;

[0027] It should be noted that the locking component 7 includes a mounting block 701. The mounting block 701 is fixedly embedded in the limit ring 6. A cavity 702 is provided inside the mounting block 701. A slider 703 is slidably inserted into the cavity 702;

[0028] It further includes a return spring 704. One end of the return spring 704 is fixedly connected to one inner wall of the cavity 702, and the other end of the return spring 704 is fixedly connected to one side of the slider 703;

[0029] One end of the slider 703 is provided with a wedge portion 8. A wedge groove 9 corresponding to the wedge portion 8 is provided on the outer wall of the filter element 1. The wedge portion 8 is inserted into the wedge groove 9;

[0030] By adopting the above case, when the filter element 1 needs to be installed, the filter element 1 can be inserted into the jack 4, and the bottom end of the filter element 1 can be inserted into the limit ring 6. At the same time, the bottom end of the filter element 1 will squeeze the wedge portion 8, thereby driving the slider 703 to slide into the cavity 702. At this time, the return spring 704 is in a compressed state. When the wedge portion 8 is aligned with the wedge groove 9, the return spring 704 is used to firmly insert the wedge portion 8 into the wedge groove 9, thereby realizing the function of quickly positioning the filter element 1;
