Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a pre-filter that mimics fish gill filtration. Background Technology

[0002] The pre-filter inspired by fish gills is inspired by the structure of fish gills. Fish breathe and filter impurities from the water through their gills; their tightly packed and highly efficient gill filaments can filter out tiny particles. Based on this principle, the pre-filter uses a biomimetic gill design, mimicking the breathing and filtration functions of fish gills to achieve precise filtration of impurities in the water. However, after prolonged use, existing pre-filters with fish gill-inspired designs tend to accumulate impurities and particulate matter on the filter screen, leading to clogging. This necessitates disassembling and cleaning the filter screen, followed by reinstallation. However, this disassembly and reinstallation process is cumbersome, time-consuming, and labor-intensive.

[0003] To address the above problems, this utility model proposes a pre-filter that mimics fish gill filtration. Utility Model Content

[0004] The purpose of this invention is to provide a pre-filter that mimics fish gill filtration, thereby solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-filter that mimics fish gills, comprising a flow tube body and an upper loading cylinder installed at the lower end of the flow tube body, an upper loading plate fixedly connected to the outer wall of the upper loading cylinder, a lower loading plate provided at the lower end of the upper loading plate, a lower loading cylinder fixedly connected to the inner wall of the lower loading plate, a fish gill-like filter screen installed on the inner wall of the lower loading cylinder, a positioning hole provided on the lower wall of the upper loading plate, a fixing mechanism installed on the upper wall of the lower loading plate, and a control component installed on one side of the upper loading plate;

[0006] The fixing mechanism includes a positioning rod whose lower end is fixedly connected to the lower plate. A mounting groove is provided on one side of the positioning rod. A movable plate is slidably connected to the inner wall of the mounting groove. A fixing block is fixedly connected to one end of the movable plate. A spring block is fixedly connected to the end of the movable plate away from the fixing block. An external support spring is fixedly connected to the inner wall of the spring block. The ends of the spring block and the external support spring away from the movable plate are both fixedly connected to the bottom of the mounting groove.

[0007] Furthermore, a fixing hole is provided on the side wall of the positioning hole, which is used to engage the fixing block.

[0008] Furthermore, the fixed block is trapezoidal in shape, and the inclined surface of the fixed block is away from the movable plate.

[0009] Furthermore, the elastic block has a hemispherical structure and is a component made of rubber.

[0010] Furthermore, the control component includes a control block that penetrates the outer wall of the upper plate. The control block is hollow inside and is made of rubber. A middle connecting block is fixedly connected to both sides of the opening on one side of the control block. A top rod body is slidably connected to the inner wall of the two sets of middle connecting blocks. An elastic element is sleeved on the outer wall of the top rod body. One end of the elastic element is fixedly connected to the middle connecting block, and the other end is fixedly connected to the inner wall of the control block.

[0011] Furthermore, one end of the push rod body is fixedly connected to the inner wall of the control block, and the other end of the push rod body extends to the inner wall of the fixing hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model proposes a pre-filter that mimics fish gills. After the positioning rod is fully inserted into the positioning hole, the reaction force of the elastic block and the outer support spring will cause the fixing block to engage with the inner wall of the fixing hole. The fixing block is fixed through its structure, and the installation is complete. When it is necessary to clean the mimic fish gill filter and disassemble it, simply press the control block. The outer wall of the control block will be recessed inward, which will drive the main body of the top rod to push the fixing block out of the fixing hole. At this time, pull down the lower loading cylinder, which will drive the positioning rod on the lower loading plate to be pulled out from the positioning hole on the lower wall of the upper loading plate, and the disassembly is completed. The installation and disassembly operations are extremely convenient, saving time and effort. It solves the problem that the disassembly and installation operations of the filter screen are cumbersome and time-consuming. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 To address the issues of cumbersome and time-consuming disassembly and installation of filters, the following preferred technical solutions are provided:

[0021] A pre-filter with simulated fish gills includes a flow tube body 1 and an upper loading cylinder 2 installed at the lower end of the flow tube body 1. An upper loading plate 4 is fixedly connected to the outer wall of the upper loading cylinder 2. A lower loading plate 5 is provided at the lower end of the upper loading plate 4. A lower loading cylinder 6 is fixedly connected to the inner wall of the lower loading plate 5. A simulated fish gill filter screen 7 is installed on the inner wall of the lower loading cylinder 6. A positioning hole is provided on the lower wall of the upper loading plate 4. A fixing mechanism 8 is installed on the upper wall of the lower loading plate 5. A control component 9 is installed on one side of the upper loading plate 4. The fixing mechanism 8 includes a positioning rod 81 whose lower end is fixedly connected to the lower loading plate 5. An installation groove 82 is provided on one side of the positioning rod 81. A movable plate 83 is slidably connected to the inner wall. A fixed block 84 is fixedly connected to one end of the movable plate 83. An elastic block 85 is fixedly connected to the end of the movable plate 83 away from the fixed block 84. An external support spring 86 is fixedly connected to the inner wall of the elastic block 85. The ends of the elastic block 85 and the external support spring 86 away from the movable plate 83 are both fixedly connected to the bottom of the mounting groove 82. A fixing hole 87 is provided on the side wall of the positioning hole. The fixing hole 87 is used to snap the fixed block 84. The fixed block 84 is trapezoidal in shape, and the inclined surface of the fixed block 84 is away from the movable plate 83. The elastic block 85 is a hemispherical structure and is a component made of rubber.

[0022] The control component 9 includes a control block 91 that penetrates the outer wall of the upper plate 4. The control block 91 is hollow inside and is made of rubber. A middle connecting block 92 is fixedly connected to both sides of the opening on one side of the control block 91. A top rod body 94 is slidably connected to the inner wall of the two sets of middle connecting blocks 92. An elastic element 93 is sleeved on the outer wall of the top rod body 94. One end of the elastic element 93 is fixedly connected to the middle connecting block 92, and the other end is fixedly connected to the inner wall of the control block 91. One end of the top rod body 94 is fixedly connected to the inner wall of the control block 91, and the other end of the top rod body 94 leads to the inner wall of the fixing hole 87.

[0023] Specifically, when installing the simulated fish gill filter 7, first align the positioning rod 81 on the lower plate 5 with the positioning hole on the lower wall of the upper plate 4, and gradually insert the positioning rod 81 into the positioning hole. At this time, the fixing block 84 is pressed back into the mounting groove 82, and the elastic block 85 and the outer support spring 86 are pressed together by the movable plate 83. After the positioning rod 81 is fully inserted into the positioning hole, the reaction force of the elastic block 85 and the outer support spring 86 will drive the fixing block 84 to engage with the inner wall of the fixing hole 87. The fixing is completed through the structure of the fixing block 84, and the installation is then complete. When the artificial gill filter 7 needs to be disassembled for cleaning, simply press the control block 91. The outer wall of the control block 91 will be recessed inward, which will drive the top rod body 94 to push the fixing block 84 out of the fixing hole 87. At this time, pull down the lower loading cylinder 6, which will drive the positioning rod 81 on the lower loading plate 5 to be pulled out from the positioning hole on the lower wall of the upper loading plate 4. The disassembly can then be completed. The installation and disassembly operations are extremely convenient, saving time and effort. This solves the problem that the disassembly and installation operations of the filter screen are relatively cumbersome and take too long.
