[0002] Pure water was originally produced by the US scientific community in order to develop ultra-pure materials (semiconductor raw materials, nano-fine ceramic materials, etc.) using distillation, deionization, reverse osmosis technology or other appropriate supercritical fine technology. Today, ultrapure water has been widely used in biology, medicine, automobiles and other fields. In addition to water molecules (H2O), this water contains almost no impurities, bacteria, viruses, organic matter such as chlorinated dioxins, and of course no mineral trace elements needed by the human body. Ultrapure water has no hardness and tastes sweet. It is often called soft water and can be drunk directly or boiled for drinking.

Through the self-locking adjustment mechanism 4, the two sliders 3 can be controlled to move away from each other, thereby driving the first support plate 5 and the second support plate 6 to move away from each other. By moving the first support plate 5 and the second support plate 6 away from each other, the first ring 7, the second ring 8 and the third ring 9 on the left and right sides can be driven to move away from each other, thereby facilitating the disassembly of the RO reverse osmosis filter cartridge 10. The device can disassemble multiple RO reverse osmosis filter cartridges 10 at the same time, which provides convenience for subsequent batch replacement and saves physical strength.

[0024] The ultrapure water equipment body 1 also includes an inlet hose 16 and an outlet hose 17 arranged on the surface. The end of the inlet hose 16 is fixedly sleeved on the side of the first cap 11, and the end of the outlet hose 17 is fixedly sleeved on the side of the third cap 13. The sleeve connection between the end of the inlet hose 16 and the first cap 11 can facilitate the disassembly of the first cap 11, and the sleeve connection between the end of the outlet hose 17 and the third cap 13 can facilitate the disassembly of the third cap 13.

[0025] The middle parts of the water inlet hose 16 and the water outlet hose 17 are both bellows expansion tubes. By providing the bellows expansion tubes and utilizing the bellows expansion tubes for expansion and contraction, the first support plate 5 and the second support plate 6 can be adapted to move away from each other or close to each other.

[0026] The outer surfaces of both ends of the RO reverse osmosis filter cartridge 10 are fixedly connected with sealing rubber rings 18. By providing the sealing rubber rings 18, leakage can be effectively avoided after the RO reverse osmosis filter cartridge 10 is installed on the inner side of the ring.

[0027] The inner sides of the first cap 11, the second cap 12 and the third cap 13 are all provided with internal threads, and the outer surfaces of the ends of the first ring 7, the second ring 8 and the third ring 9 are all provided with external threads that cooperate with the internal threads.

[0028] The first connecting pipe assembly 14 and the second connecting pipe assembly 15 each include a bent pipe 19 and two sleeves 20, the two sleeves 20 are respectively fixedly connected to the two ends of the bent pipe 19, and the first cap 11, the second cap 12 and the third cap 13 can be sleeved and fixed with the sleeves 20. This design can facilitate the disassembly and installation of the first connecting pipe assembly 14 and the second connecting pipe assembly 15, and facilitates the disassembly of the second cap 12 by disassembling the first connecting pipe assembly 14 or the second connecting pipe assembly 15.

[0029] The self-locking adjustment mechanism 4 includes a bidirectional lead screw 21, a worm wheel 22, a worm 23, a side plate 24, a drive rod 25 and a crank 26. The side plate 24 is fixedly connected to the side of the ultrapure water equipment body 1, the bidirectional lead screw 21 is rotatably connected to the inner wall of the strip slide 2, and the slider 3 is threadedly connected to the bidirectional lead screw 21, the worm wheel 22 is fixedly connected to the rotating end of the bidirectional lead screw 21, the worm 23 is rotatably connected between the two side plates 24, the drive rod 25 is fixedly connected to the rotating end of the worm 23, and the crank 26 is fixedly connected to the end of the drive rod 25, and The worm 23 and the worm wheel 22 mesh with each other. When the distance between the two sliders 3 needs to be adjusted, the crank 26 can be used to rotate the driving rod 25, thereby driving the worm 23 to rotate. The meshing transmission of the worm 23 and the worm wheel 22 can drive the bidirectional screw 21 to rotate. The slider 3 is limited by the strip slide 2, so that the distance between the two sliders 3 can be adjusted. The self-locking principle of the worm 23 and the worm wheel 22 can be used to effectively prevent the two sliders 3 from moving away from each other, thereby ensuring the firmness of the RO reverse osmosis filter cartridge 10 after installation.

[0030] Working principle: When the RO reverse osmosis membrane pure water equipment is in use, water will pass through the first cap 11 from the water inlet hose 16 and then enter the RO reverse osmosis filter cartridge 10 inside the first ring 7, then pass through the first connecting pipe assembly 14 and the second cap 12, and then enter the RO reverse osmosis filter cartridge 10 inside the second ring 8, and finally pass through the second connecting pipe assembly 15 and the third cap 13, and finally enter the RO reverse osmosis filter cartridge 10 inside the third ring 9, and enter the ultrapure water equipment body 1 from the water outlet hose 17. When the RO reverse osmosis filter cartridge 10 needs to be replaced separately, the corresponding cap can be removed, and the RO reverse osmosis filter cartridge 10 can be pulled out from the side for replacement. When multiple RO reverse osmosis filter cartridges 10 need to be replaced, the crank 26 can be turned to drive the worm 23 to rotate, and then the worm 23 and the worm wheel 22 are engaged to drive the bidirectional lead screw 21 to rotate, so that the two sliders 3 can be moved away from each other, thereby driving the first support plate 5 and the second support plate 6 away from each other. By moving the first support plate 5 and the second support plate 6 away from each other, the first ring 7, the second ring 8 and the third ring 9 on the left and right sides can be driven away from each other, thereby facilitating the disassembly of the RO reverse osmosis filter cartridge 10. The device can disassemble multiple RO reverse osmosis filter cartridges 10 at the same time, which provides convenience for subsequent batch replacement and saves physical strength.
