Technical Field

[0001] This utility model belongs to the field of water purifier filter technology, and in particular relates to a fixing structure for water purifier filter elements. Background Technology

[0002] With the increasing health awareness and higher requirements for drinking water quality, water purifiers, as devices that can effectively filter impurities, heavy metals, microorganisms and other harmful substances in water, have been widely used in various scenarios such as homes and offices. Among the core components of water purifiers, the filter element is the key carrier for achieving water purification. Its filtration effect directly determines the final water purification quality of the water purifier. The stable installation of the filter element depends on a reliable fixing structure. Therefore, a high-performance water purifier filter element fixing structure is needed to ensure the normal operation of the filter element.

[0003] However, the existing fixing structure is difficult to adapt to the specifications of various integrated filter elements during use. This not only limits the applicability of the fixing part, but also requires each type of filter element to be matched with a dedicated fixing structure, which increases the cost and complexity of use and reduces the safety of equipment use.

By setting a compensation fixing part, the problem of existing fixing structures being difficult to adapt to the specifications of various integrated filter cartridges during use is solved. This not only limits the applicability of the fixing part, but also causes each type of filter cartridge to be matched with a dedicated fixing structure, increasing the cost and complexity of use, and reducing the safety of equipment use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fixing structure for water purifier filter cartridges, comprising a mounting box and a plurality of integrated filter cartridges disposed within the mounting box, and further comprising: a compensation fixing part, wherein a plurality of compensation fixing parts are provided and each plurality of compensation fixing parts is installed within the mounting box; a locking part, wherein a plurality of locking parts are provided and each plurality of locking parts is respectively installed on a plurality of compensation fixing parts; the compensation fixing part includes a fixing component, wherein the fixing component is installed on the mounting box; a compensation component, wherein the compensation component is disposed on the fixing component; the fixing component includes two semi-circular groove blocks disposed within the mounting box, wherein the semi-circular groove blocks located on the rear side are connected to the mounting box. The two semicircular groove blocks are fixedly connected, each with several circular holes. Hollow cylinders are fixedly connected within each of the circular holes, and fixing rods are installed within each of the hollow cylinders. The fixing rods extend from their respective sides to the hollow cylinders and are slidably connected to each hollow cylinder. A hinge is provided between the two semicircular groove blocks. Five integrated filter elements, compensation fixing parts, and locking parts are provided, arranged in a linear array. The hinge includes a hinge rod located on the right side of each of the two semicircular groove blocks, and both semicircular groove blocks are hinged to the hinge rod. The hinge rod is cylindrical.

[0007] Furthermore, the locking part includes a support assembly mounted on two semi-circular recessed blocks; and a locking assembly mounted on the support assembly.

[0008] Furthermore, the compensation component includes circular limiting plates slidably connected within a plurality of hollow cylinders, the plurality of circular limiting plates being fixedly connected to a plurality of fixed rods, each of the plurality of hollow cylinders being provided with a spring, the sides of the plurality of springs away from the plurality of circular limiting plates being fixedly connected to the plurality of hollow cylinders, and the sides of the plurality of springs close to each other being fixedly connected to the plurality of circular limiting plates; the plurality of circular limiting plates are located on the sides of the plurality of fixed rods that are far apart from each other.

[0009] Furthermore, the support assembly includes rectangular handles fixedly connected to the left sides of the two semi-circular recessed blocks respectively. A rectangular groove is formed on the rectangular handle located on the front side. A rectangular ring is fixedly connected to the inner wall of the rectangular groove on the side away from the front semi-circular recessed block. A T-shaped slider is slidably connected in the rectangular groove. The T-shaped slider is slidably connected to the inner wall of the rectangular ring. An elastic element is provided in the rectangular groove. The elastic element includes two sliding rods fixedly connected in the rectangular groove. The left side of each of the two sliding rods is fixedly connected to the rectangular ring. Both sliding rods pass through the T-shaped slider and are slidably connected to the T-shaped slider. A second spring is sleeved on the outer wall of each of the two sliding rods. The side of each second spring away from the rectangular ring is fixedly connected to the T-shaped slider, and the side of each second spring away from the T-shaped slider is fixedly connected to the rectangular ring.

The fixed plate is adapted to the locking block through the limiting hole.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a compensation fixing part, the integrated filter element is placed inside the compensation fixing part. By rotating the front semi-circular groove block, it moves closer to the corresponding rear component, causing the relevant hollow cylinder and fixing rod to move closer to each other to squeeze the filter element. This causes the fixing rod to push open the circular limit plate and squeeze the first spring. With the help of the elastic force of the first spring, the fixing rods with different degrees of compression can fit tightly against the surface of the filter element according to its shape, achieving a stable fixation. Multiple filter elements can be fixed in this way, which can flexibly adapt to various specifications of integrated filter elements. This breaks the limitation of traditional fixing structures on filter element specifications, eliminates the need for dedicated fixing structures for multiple filter elements, and greatly reduces the cost of use and the complexity of operation.

[0013] 2. By setting a locking part, during fixing, the front semi-circular groove block drives the fixing plate to move, and the arc surface of the locking block presses against the fixing plate, causing the fixing plate to drive the T-shaped slider to move to the left on the rectangular groove, rectangular ring and slide rod and press the second spring; when the limiting hole of the fixing plate corresponds to the locking block, the elastic force of the second spring pushes the limiting hole to lock on the locking block, and the two semi-circular groove blocks are fixed by the right angle surface of the locking block; pulling the fixing plate to make the limiting hole disengage from the locking block can open the front semi-circular groove block, which greatly simplifies the overall process of fixing the filter element, improves the operation efficiency, and avoids the installation failure problem caused by the locking loosening after the filter element is fixed.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] A specific application of this embodiment is as follows: In use, several integrated filter elements 112 are placed in the compensation fixing part 2. At this time, the semi-circular groove block 211 located on the front side is pulled to rotate on the hinge rod 215 and move closer to the semi-circular groove block 211 located on the rear side. At this time, the semi-circular groove block 211 located on the front side drives the corresponding hollow cylinders 213 and fixing rods 214 to move closer to the hollow cylinders 213 and fixing rods 214 on the semi-circular groove block 211 located on the rear side, thereby squeezing the integrated filter element 112. The force causes several fixed rods 214 to move away from each other. At this time, the fixed rods 214 push several circular limiting plates 221 to slide within the corresponding hollow cylinders 213. During this process, several springs 222 will be compressed, deformed, and generate elastic force. Depending on the shape of the integrated filter element 112, the fixed rods 214 are compressed to different degrees. Under the action of the elastic force of the springs 222, the fixed rods 214 are pressed tightly against the surface of the integrated filter element 112, thereby fixing the integrated filter element 112. The operation process drives several compensation fixing parts 2 to fix several integrated filter elements 112 respectively. During the fixing process, the semi-circular groove block 211 located on the front side drives the corresponding fixing plate 321 to move. At this time, under the action of the arc surface of the locking block 323, the fixing plate 321 is squeezed. At this time, the fixing plate 321 drives the T-shaped slider 314 to slide on the rectangular groove 312, the rectangular ring 313 and the two sliding rods 315 and move to the left. During this process, the two springs 316 will be squeezed and deformed to generate elastic force. When the fixing plate 321 drives the limiting hole 322 to correspond with the locking block 323, under the action of the elastic force of the two springs 316, the fixing plate 321 drives the limiting hole 322 to lock onto the locking block 323. Under the action of the right angle surface of the locking block 323, the two semi-circular groove blocks 211 are fixed together. By pulling the fixing plate 321, the limiting hole 322 is moved away from the locking block 323, thereby opening the semi-circular groove block 211 located on the front side. Under the action of the compensation fixing part 2 and the locking part 3, the integrated filter element 112 is fixed and released.
