Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a clamp which is convenient for installing and disassembling a filter element. Background Art

[0002] At present, water purifiers are mainly developing in the direction of self-replacement. Generally, when installing a filter element in a water purifier, you need to first insert the filter element rod into the water channel plate, and then press down the filter element clamp to lock the filter element.

[0003] Existing water purifiers often use double O-ring seals at the joints of the water channel plate, which creates great resistance during insertion. Users often cannot clearly sense whether the filter is fully inserted, so water leaks often occur due to improper insertion of the filter element, resulting in complaints. When removing the filter element, it is difficult to pull out the filter element due to the high internal pressure, affecting the consumer experience. Summary of the invention

[0004] In view of the above problems existing in the existing water purifiers, the present invention aims to provide a clamp which is convenient for installation and removal of a filter element and has high installation accuracy and avoids water leakage.

[0005] The specific technical solutions are as follows:

[0006] A clamp for facilitating installation and removal of a filter element, used for assembly and removal between a filter element and a water purifier body, wherein the top side of the filter element is provided with a water inlet and outlet hole, the water purifier body is provided with a waterway plate, and the waterway plate is provided with a filter element mounting column, when the filter element is in an installed state, the water inlet and outlet hole is in contact with the filter element mounting column, and when the filter element is in a removed state, the water inlet and outlet hole is separated from the filter element mounting column, comprising:

[0007] A handle, the two ends of which are hinged to the top two sides of the filter element body respectively;

[0008] A push-pull structure, the push-pull structure is arranged between the handle and the waterway plate, and is used to pull the filter element inward or push the filter element outward so that the water inlet and outlet holes contact or separate from the filter element mounting column. The push-pull structure includes a first state and a second state. When the handle is pressed down and rotated, the push-pull structure is in the first state, and the handle pulls the filter element inward through the push-pull structure so that the water inlet and outlet holes contact the filter element mounting column. When the handle is lifted and rotated, the push-pull structure is in the second state, and the handle pushes the filter element outward through the push-pull structure so that the water inlet and outlet holes separate from the filter element mounting column.

[0009] The limiting structure is arranged on the handle. When the handle is pressed down and rotated, and the water inlet and outlet holes are fully matched with the filter element installation column, the limiting structure and the waterway plate are limited and matched to limit the circumference of the handle.

[0010] As a further improvement and optimization of this solution, the push-pull structure includes two groups of push-pull components, the two push-pull components are respectively arranged on both sides of the waterway plate, and each push-pull component includes:

[0011] A push-out block, the push-out block is arranged on the handle and has a push-out inclined surface;

[0012] An ejector block, the ejector block is arranged on the waterway plate, and when the handle is lifted and rotated upward, the ejector block contacts the push inclined surface to push the filter element outward, thereby causing the water inlet and outlet holes to be separated from the filter element mounting column outward;

[0013] A pulling resistance block, wherein the pulling resistance block is arranged on the handle;

[0014] The pulling guide block is an arc-shaped structure and is arranged on the waterway plate, and the back arc surface of the pulling guide block is limitedly matched with the pulling contact block. When the handle is pressed down and rotated, the pulling contact block moves along the arc direction of the back arc surface of the pulling guide block to pull the pulling guide block inward, thereby making the water inlet and outlet holes contact the filter element mounting column inward.

[0015] As a further improvement and optimization of the present solution, an extension portion is extended outward from the top of the pulling resistance block.

[0016] As a further improvement and optimization of the present solution, sleeves are provided at both ends of the handle, hinge shafts are provided on both sides of the top of the filter element body, and the two sleeves are rotatably sleeved on the outside of the two hinge shafts respectively.

[0017] As a further improvement and optimization of this solution, the two pushing blocks in the two groups of the push-pull assemblies are respectively arranged on the outside of the two sleeves.

[0018] As a further improvement and optimization of the present solution, the two pushing inclined surfaces on the two pushing blocks are respectively arranged tangent to the outer circumferential surfaces of the two sleeves.

[0019] As a further improvement and optimization of the present solution, the limiting structure includes two limiting flanges, which are respectively arranged on the outer sides of the two ends of the handle. When the handle is pressed down and rotated, and the water inlet and outlet holes are fully matched with the filter element mounting column, the two limiting flanges are respectively limited and matched with the two sides of the bottom of the waterway plate.

[0020] As a further improvement and optimization of this solution, the two limiting flanges are respectively arranged at the bottom of the two pulling resistance blocks in the two groups of the push-pull components.

[0021] Compared with the prior art, the above technical solution has the following positive effects:

[0022] (1) In the utility model, when the filter element is disassembled and assembled, the handle is turned and the pushing structure is used to drive the water inlet and outlet holes to separate from or contact the filter element installation column, thereby realizing the disassembly and assembly of the filter element, which is convenient and quick.

[0023] (2) When installing the filter element in the utility model, the handle is pressed down and rotated until the limit structure cooperates with the limit of the waterway plate, thereby limiting the circumference of the handle. At this time, the filter element installation column is fully extended into the water inlet and outlet holes, effectively avoiding water leakage caused by improper installation of the filter element installation column.

[0024] (3) In the present invention, when removing the filter element, the handle is lifted up and rotated, and the ejection block contacts the push slope to push the filter element outward, thereby separating the water inlet and outlet holes from the filter element mounting column, and completing the removal of the filter element. When installing the filter element, the handle is pressed down and rotated, and the contact block is pulled along the arc direction of the back arc surface of the pulling guide block to pull the pulling guide block inward, thereby making the water inlet and outlet holes fully contact and cooperate with the filter element mounting column, and completing the installation of the filter element. The disassembly and assembly method saves time and effort, and greatly reduces the difficulty of disassembly and assembly.

[0025] (4) In the utility model, the top of the pulling resistance block extends outwardly. When installing the filter element, lift the handle, align the water inlet and outlet holes with the filter element installation column on the waterway plate, and insert it. Slightly press the handle so that the extended part first cooperates with the pulling guide block on the waterway plate, and then continue to press the handle down so that the pulling resistance block and the pulling guide block are fully cooperated, thereby making the installation of the filter element more labor-saving.

Figure 2 This is a schematic diagram of the structure of a clamp handle for facilitating installation and removal of a filter element according to the utility model. Figure 3 This is a schematic diagram of the structure of a filter element body of a clamp that facilitates the installation and removal of the filter element in the utility model. Figure 4 This is a schematic diagram of the overall structure of a waterway plate of a clamp that facilitates the installation and removal of a filter element in the utility model. Figure 5 This is a schematic diagram of the steps for disassembling a waterway plate of a clamp that facilitates the installation and disassembly of a filter element in the utility model, as shown in FIG. Figures 1 to 5 As shown, a clamp for facilitating installation and removal of a filter element 1 in a preferred embodiment is shown, which is used for assembly and removal between the filter element 1 and a water purifier body (not shown in the figure). The top side of the filter element 1 has a water inlet and outlet hole 11, and the water purifier body has a waterway plate 3, and the waterway plate 3 has a filter element mounting column 31. When the filter element 1 is in an installed state, the water inlet and outlet hole 11 contacts the filter element mounting column 31, and when the filter element 1 is in a disassembled state, the water inlet and outlet hole 11 is separated from the filter element mounting column 31, including: a handle 2, a push-pull structure 4 and a limiting structure 5, the two ends of the handle 2 are respectively hinged on the top two sides of the filter element 1 body, and the push-pull structure 4 is arranged between the handle 2 and the waterway plate 3, and is used to pull inward or push outward. The filter element 1 is configured to make the water inlet and outlet holes 11 contact or separate from the filter element mounting column 31, and the push-pull structure 4 includes a first state and a second state. When the handle 2 is pressed down and rotated, the push-pull structure 4 is in the first state, and the handle 2 pulls the filter element 1 inward through the push-pull structure 4 to make the water inlet and outlet holes 11 contact with the filter element mounting column 31. When the handle 2 is lifted and rotated, the push-pull structure 4 is in the second state, and the handle 2 pushes the filter element 1 outward through the push-pull structure 4 to make the water inlet and outlet holes 11 separate from the filter element mounting column 31. The limiting structure 5 is provided on the handle 2. When the handle 2 is pressed down and rotated, and the water inlet and outlet holes 11 are fully matched with the filter element mounting column 31, the limiting structure 5 is limited and matched with the waterway plate 3 to limit the handle 2 circumference.

[0034] In the present embodiment, when the filter element 1 is disassembled and assembled, the handle is turned and the pushing structure is used to drive the water inlet and outlet holes 11 to separate from or contact the filter element mounting column 31, thereby achieving the disassembly and assembly of the filter element 1, which is convenient and quick.

[0035] When installing the filter element 1 in the present embodiment, the handle is pressed down and rotated until the limiting structure 5 cooperates with the waterway plate 3 to limit the handle 2 circumference. At this time, the filter element installation column 31 is fully extended into the water inlet and outlet holes 11, effectively avoiding water leakage caused by improper installation of the filter element installation column 31.

[0036] Further, as a preferred embodiment, the push-pull structure 4 includes two groups of push-pull components, the two push-pull components are respectively arranged on both sides of the waterway plate 3, each push-pull component includes a push-out block 42, an ejection block 43, a pull-resistance block 41 and a pull-guide block 44, the push-out block 42 is arranged on the handle 2, and the push-out block 42 has a push inclined surface 421, and the ejection block 43 is arranged on the waterway plate 3. When the handle 2 is lifted and rotated upward, the ejection block 43 and the push inclined surface 421 are in conflict, so that the filter element 1 is moved to The water inlet and outlet holes 11 are pushed outwardly, thereby separating the filter element mounting column 31 from the outside. The pulling resistance block 41 is arranged on the handle 2. The pulling guide block 44 is an arc-shaped structure and is arranged on the waterway plate 3. The back arc surface of the pulling guide block 44 cooperates with the pulling contact block limiter. When the handle 2 is pressed down and rotated, the pulling contact block moves along the arc direction of the back arc surface of the pulling guide block 44 to pull the pulling guide block 44 inwardly, thereby making the water inlet and outlet holes 11 completely contact the filter element mounting column 31 inwardly.

[0037] In the present embodiment, when the filter element 1 is disassembled, the handle 2 is lifted up and rotated, and the ejection block 43 contacts the push slope 421 to push the filter element 1 outward, thereby disengaging the water inlet and outlet holes 11 from the filter element mounting column 31, and completing the disassembly of the filter element 1. When the filter element 1 is installed, the handle 2 is pressed down and rotated, and the contact block 41 is pulled along the arc direction of the back arc surface of the pulling guide block 44 to pull the pulling guide block 44 inward, thereby making the water inlet and outlet holes 11 completely contact and cooperate with the filter element mounting column 31, and completing the installation of the filter element 1.
