[0033] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0034] The present invention relates to a filter element buckle structure, comprising a mounting cover 100, a lifting rod 200, a buckle 300 and a guide block 400.

[0035] In this embodiment, Figure 1 and Figure 2 As shown, the mounting cover 100 can be composed of an upper cover body 101 and a lower cover body 102, and the lower cover body 102 is a disc-shaped structure. The mounting cover 100 is connected to the end of the cylinder of the filter element through the lower cover body 102 by means of spin welding or the like. The lifting rod 200 is in an arc shape, and the two ends of the lifting rod 200 can be rotatably mounted on the upper cover body 101 of the mounting cover 100 by means of a snap connection. The lifting rod 200 is turned up and down on the mounting cover 100 around its two ends. Figure 4As shown, the lifting rod 200 can be turned upward to a 90° position relative to the upper cover body (101); Figure 3 As shown, when the lifting rod 200 is flipped downward, it flips over to overlap the end surface of the mounting cover 100, and can be flush with or slightly lower than the end surface of the mounting cover 100. In the direction shown in the figure, the two clips 300 are symmetrically installed inside the mounting cover 100 with the front and back facing each other. The two clips 300 are on the same straight line in the horizontal plane. A set of openings are symmetrically opened on the front and back sides of the mounting cover 100. The clips 300 translate along a straight line inside the mounting cover 100. The two clips 300 face each other at the ends of the middle part of the mounting cover 100, and the other ends telescopically move inside and outside the mounting cover 100 through the openings opened at the front and back. Two guide blocks 400 are set on the left and right sides inside the mounting cover 100. The two guide blocks 400 are symmetrically installed. The guide blocks 400 and the clips 300 are located on the same horizontal plane, and the two guide blocks 400 are on the same straight line. The two guide blocks 400 and the two clips 300 are arranged in a cross-like arrangement. The straight line between the two guide blocks 400 and the straight line between the two clips 300 is perpendicular to each other in horizontal space, and the two guide blocks 400 and the two clips 300 are sequentially slidably connected. The two guide blocks 400 can move closer to or farther from each other within the mounting cover 100, that is, the two guide blocks 400 can move relative to each other toward the center of the mounting cover 100 or away from the center of the mounting cover 100. The guide blocks 400 and the clips 300 move synchronously, that is, the guide blocks 400 and the clips 300 simultaneously move toward the center of the mounting cover 100, with the outward ends of the clips 300 retracting into the interior of the mounting cover 100 during this movement; or the guide blocks 400 and the clips 300 simultaneously move away from the center of the mounting cover 100 toward the exterior of the mounting cover 100, in which case the clips 300 extend outward. Among them, the lifting rod 200 and the guide block 400 are linked. When the lifting rod 200 is flipped in one direction, the two guide blocks 400 can be pushed inward, and the buckle 300 is also retracted toward the inside of the installation cover 100. When the lifting rod 200 is rotated in the other direction, the buckle 300 and the guide block 400 can be translated outward and reset. In this embodiment, preferably, when the lifting rod 200 is flipped upward relative to the installation cover 100, it drives the guide block 400 and the buckle 300 to retract toward the inside of the installation cover 100; when the lifting rod 200 is flipped downward relative to the installation cover 100, the guide block 400 and the buckle 300 can be translated outward and reset. The cross-distribution linkage of the guide block 400 and the buckle 300 is used to ensure the stability of the two buckles 300 when moving relative to the installation cover 100. In actual use, the water purification device applies the filter element buckle structure. The user connects it to the water purification device through the extended buckle 300. By flipping the lifting rod 200, the guide block 400 and the buckle 300 can be quickly driven to move, so as to quickly install and remove the filter element.

[0036] like Figure 1 and Figure 3 As shown, a guide groove 310 is provided on the end of the buckle 300 facing the interior of the mounting cover 100. The guide groove 310 is concave toward the outer end of the buckle 300. First guide surfaces 311 are provided on either side of the guide groove 310. The first guide surfaces 311 are inclined from the left / right side of the buckle 300 toward the centerline. The first guide surfaces 311 can be curved, preferably flat. The first guide surfaces 311 on either side of the same guide groove 310 are symmetrically arranged. Second guide surfaces 410 are symmetrically provided on the front and rear sides of the guide block 400. The second guide surfaces 410 mate with the first guide surfaces 311, and the second guide surfaces can be curved or flat. The two second guide surfaces 410 of the same guide block 400 slide into the guide grooves 310 of the two buckles 300, respectively. Each second guide surface 410 is slidably connected to an adjacent first guide surface 311. The two first guide surfaces 311 and the two second guide surfaces 410 are spatially arranged in a diamond or rectangular shape. In this embodiment, the first guide surface 311 and the second guide surface 410 are flat surfaces. The guide groove 310 is in a concave V-shape. The guide block 400 is triangular, preferably an isosceles triangle or an equilateral triangle. During operation, when the two guide blocks 400 move relatively far apart to the left and right sides, the two first guide surfaces 311 on the same buckle 300 are slid by the adjacent second guide surfaces 410 on the two guide blocks 400, and the buckle 300 is pushed out of the mounting cover 100 by opening the two guide blocks 400. When the two buckles 300 are relatively close to each other, the two first guide surfaces 311 of the same guide groove 310 are used to push the two guide blocks 400 inward and close together. The cross distribution of the guide groove 310 and the guide block 400, combined with the sliding connection of the first guide surface 311 and the second guide surface 410 in a spatial rhombus or rectangular distribution, the linkage between the locking block and the guide block 400 is very stable.

[0037] In some specific embodiments of the present invention, Figure 1As shown, a third guide surface 420 is provided on the guide block 400. The outer end of the guide block 400 extends outward to form an axial section, and the third guide surface 420 is located on this axial section. The third guide surface 420 is inclined toward the outer upper side of the mounting cover 100. That is, in the direction shown in the figure, the third guide surface 420 of the guide block 400 on the left side is inclined from the lower left to the upper right, and the third guide surface 420 of the guide block 400 on the right side is inclined from the lower right to the upper left. A fourth guide surface 210 is provided at both ends of the lifting rod 200, and the fourth guide surface 210 is oriented toward the third guide surface 420. In the direction shown in the figure, when the lifting rod 200 is flipped to be flush with the mounting cover 100, the fourth guide surface 210 is inclined from the upper front to the lower rear. When the lifting lever 200 flips upward, the end of the lifting lever 200 where the fourth guide surface 210 is located abuts the third guide surface 420. The sliding connection between the fourth guide surface 210 and the third guide surface 420 pushes the guide block 400 toward the interior of the mounting cover 100, thereby causing the latch 300 to retract toward the interior of the mounting cover 100. The third guide surface 420 and the fourth guide surface 210 can be located and slidably connected within the mounting cover 100. The end of the lifting lever 200 extends into the mounting cover 100, while the fourth guide surface 210 is located within the mounting cover 100. Simultaneously, the guide block 400 moves within the mounting cover 100, concealing both the third guide surface 420 and the fourth guide surface 210 within the mounting cover 100. In this embodiment, an opening can be provided in the sidewall of the mounting cover 100 corresponding to the outer end of the guide block 400, so that the third guide surface 420 moves with the guide block 400 within and outside the mounting cover 100. The fourth guide surface 210 is located on the end of the lifting rod 200 outside the mounting cover 100. The third guide surface 420 and the fourth guide surface 210 are located outside the mounting cover 100 and are interlocked. The third guide surface 420 and the fourth guide surface 210 can be arcuate surfaces. Preferably, the third guide surface 420 and the fourth guide surface 210 are configured as flat surfaces.

[0038] In some specific embodiments of the present invention, Figure 1 and Figure 3As shown, a plurality of first spring members 430 are disposed between the two guide blocks 400. The two ends of the first spring members 430 abut against opposing surfaces of the two guide blocks 400. When the lifting lever 200 tilts upward, pushing the guide blocks 400 toward the interior of the mounting cover 100, the first spring members 430 compress, exerting an elastic force on the guide blocks 400 on both sides, pushing them outward from the mounting cover 100. When the lifting lever 200 tilts downward, the guide blocks 400 gradually lose the thrust of the lifting lever 200. The first spring members 430 then push the guide blocks 400 toward the exterior of the mounting cover 100, thereby driving the buckle 300 to extend outward from the mounting cover 100. A second spring member 320 is disposed between the buckle 300 and the mounting cover 100. In this embodiment, mounting surfaces extend from the left and right sides of the buckle 300. One end of the second spring abuts against the inner wall of the mounting cover 100, and the other end abuts against the mounting surface of the buckle 300. When the buckle 300 extends toward the outside of the mounting cover 100, it compresses the second spring member 320, which exerts an elastic force on the buckle 300 to move toward the inside of the mounting cover 100. When the two guide blocks 400 move toward the inside of the mounting cover 100, the buckle 300 moves toward the inside of the mounting cover 100 under the action of the second spring member 320.
