[0021] See also Figure 1-5 The utility model provides a technical solution: it includes a purifier body 1, a filter plate 2 is installed inside the purifier body 1, a first slide rail 4 and a second slide rail 5 are fixed at the bottom and top of the purifier body 1 respectively by countersunk screws, the first slide rail 4 and the second slide rail 5 have the same shape, and the first slide rail 4 and the second slide rail 5 are symmetrically arranged, the first slide rail 4 and the second slide rail 5 are both composed of two concave slide rail monomers, the side length of the filter plate 2 is equal to the internal side length of the purifier body 1, and then the lower end and the upper end of the filter plate 2 are connected. A rectangular groove is opened at the position corresponding to the first slide rail 4 and the second slide rail 5, and then a T-shaped block is welded at the rectangular groove at the lower end of the filter plate 2, and a T-shaped block is also welded at the rectangular groove at the upper end of the filter plate 2. A hand-held rod 8 is glued to the middle position of the side of the filter plate 2. By manually holding the hand-held rod 8, the filter plate 2 can be inserted into the interior of the purifier body 1. First, the first slider 6 and the second slider 7 are aligned with the first slide rail 4 and the second slide rail 5 respectively. After alignment, the filter plate 2 can be inserted, and then the filter plate 2 can be fixed by using other components;

[0022] A limiting groove 10 is provided on the inner wall side of the purifier body 1, and the length of the limiting groove 10 is equal to the length of the first slide rail 4 and the second slide rail 5. A placement groove 11 is provided at the bottom of the limiting groove 10. The placement groove 11 is a groove of a rectangular structure, and the placement groove 11 does not interpenetrate with the limiting groove 10. The placement groove 11 is only located below the limiting groove 10. Then, a slot 12 is provided at the middle position of the top of the placement groove 11. The slot 12 extends upward to the upper end position of the limiting groove 10. A spring 13 is glued to the bottom of the placement groove 11, and a limiting plate 1 is glued to the top of the spring 13. 4. The limiting plate 14 and the spring 13 are in contact with a rectangular plate, and then another rectangular plate is glued in the middle of the top of the rectangular plate, which extends into the slot 12. The limiting slot 10 is separated by the limiting plate 14, and then the side of the limiting plate 14 is glued with a pull rod 15. The length of the pull rod 15 makes it extend to the outside of the placement slot 11 and is located outside the purifier body 1. Then, a baffle 16 is fixed on the side of the placement slot 11 with screws. The side length of the baffle 16 is greater than the length of the placement slot 11, and then a rectangular opening is opened on the surface of the baffle 16 corresponding to the axis of the pull rod 15. After the baffle 16 is fixed on the placement groove 11, the pull rod 15 can be moved up and down in the rectangular hole. The limit block 9 is glued at the position of the limit groove 10 on the side of the filter element plate 2 corresponding to the limit groove 10. The side length of the limit block 9 is equal to the width of the limit groove 10. Then, after holding the hand-held rod 8, the filter element plate 2 is aligned with the purifier body 1, and the limit block 9 is inserted into the limit groove 10. Then, the pull rod 15 is pulled downward.
