The filter cloth 21 frame structure is installed on the outside of the filter frame structure. First, the frame body 4 and the back plate 10 are removed from the outside of the primary filter frame 1. Then, as needed, the first filter frame 23, the second filter frame 24, and the third filter frame 25 are pulled outward. When pulling outward, the operator needs to hold down the other filter frame structures with the other hand. The filter structure that needs to be removed and replaced can be taken out. The T-shaped plate 29 can be moved out from the inside of the T-shaped groove 30. Afterward, the new filter element can be taken out to replace it. Moreover, the operation is relatively simple.

[0028] The inner side of the back plate 10 is provided with a sealing plate 11 and an outer sealing ring 12. The side of the primary filter frame 1 is provided with a sealing groove 13, and the sealing ring 12 is embedded in the inside of the sealing groove 13. Due to the installation of the sealing plate 11 and the sealing ring 12, the gaps can be sealed during the installation of the plate body to prevent water from flowing out.

[0029] The back panel 10 is provided with a frame 4 on the outside, a drying plate 5 is installed inside the frame 4, a fixing plate 6 is provided on the outside of the frame 4, and a threaded post 7 is provided on the side of the fixing plate 6.

[0032] The primary filter frame 1 has a first threaded groove 19 on its outside and a second threaded groove 20 on its outside. The fastening screw 15 is threaded to the first threaded groove 19 and the extrusion screw 18 is threaded to the second threaded groove 20. Since the first threaded groove 19 and the second threaded groove 20 are provided, the fastening screw 15 and the extrusion screw 18 can be threaded together.

[0033] The working principle of the pre-filtration structure for the water purification device is as follows: When using this pre-filtration structure, firstly, to facilitate selective replacement of the filter element, a limiting plate 22 is provided inside the pre-filtration frame 1, and a first filter frame 23, a second filter frame 24, and a third filter frame 25 are installed inside the limiting plate 22. A T-shaped plate 29 is provided at the top of the filter frame structure, and a T-shaped groove 30 is opened at the bottom of the filter frame structure. The first filter frame 33 is installed at the top of the first filter frame 23, and the second filter frame 34 is installed at the bottom of the third filter frame 25. First, the locking nut 8 on the outside of the threaded column 7 is turned in the reverse direction to remove the threaded column 7 from the inside of the sleeve frame 9, so that the frame body 4 can be disassembled. Then, the fastening screw 15 and the pressing screw 18 are turned in turn to remove the back. The sealing ring 12 on the inner side of plate 10 is removed from the sealing groove 13, allowing the back plate 10 to be disassembled. Then, the first filter frame 23, second filter frame 24, and third filter frame 25 are pulled outwards as needed. While pulling outwards, the operator needs to hold down the other filter frame structures with one hand to remove the filter structure that needs to be disassembled and replaced. When disassembling the first filter frame 23, the operator first holds down the second filter frame 24 and the third filter frame 25 with one hand, while simultaneously moving the first filter frame 23 out with the other hand. The T-shaped plate 29 is then removed from the T-slot 30, and the metal column 31 is removed from the magnetic groove 32. This allows the first filter frame 23 to be removed. Next, the quartz sand plate 26 is removed, followed by the removal of a new quartz sand plate 26. Replace the filter element as needed. Then, reinstall the first filter frame 23. Next, when removing the filter element from the second filter frame 24, the operator should hold down the first filter frame 23 and the third filter frame 25 with one hand, while simultaneously moving the second filter frame 24 out with the other hand. Remove the T-shaped plate 29 from the T-slot 30 and the metal column 31 from the magnetic slot 32. This allows the second filter frame 24 to be removed. Then, remove the activated carbon plate 27 and replace it with a new one. Reinstall the second filter frame 24. Finally, when removing the filter element from the third filter frame 25, the operator should hold down the first filter frame 23 and the second filter frame 24 with one hand, while simultaneously moving the third filter frame 24 out with the other hand. Remove the filter frame 25, then remove the T-shaped plate 29 from the T-slot 30, and remove the metal column 31 from the magnetic groove 32. This allows the third filter frame 25 to be removed. Next, remove the sponge plate 28, then replace it with a new sponge plate. Finally, reinstall the third filter frame 25. This method facilitates selective disassembly and reassembly based on actual needs and is relatively simple. After selectively replacing the filter element structure according to actual conditions, the operator removes the back plate 10, inserts the sealing ring 12 into the sealing groove 13, and then removes the fastening screw 15 and the compression screw 18. First, thread the fastening screw 15 through the mounting plate 14 and connect it to the first threaded groove 19. Then, remove the compression screw 18.The dosing screw is threaded through the vertical plate 17 and connected to the second threaded groove 20. The installation of two sets of fasteners increases the stability of the seal. To prevent the fasteners from being affected by moisture in the air, the frame 4 is removed, and the drying plate 5 is installed inside the frame 4. Next, the threaded post 7 on the side of the fixing plate 6 is threaded through the sleeve frame 9. Then, the locking nut 8 is removed and threaded to complete the assembly.
