A B mounting ring 75 is connected to the outside of the support ring 74, and the B mounting ring 75 and the support ring 74 are connected to the lower side of the outer casing 1. A B mounting groove is provided at the lower outer end of the B mounting ring 75. A B connecting pipe 76 is threadedly installed inside the B mounting groove. A bottom ring 77 is connected to the inner side of the B connecting pipe 76. A support cylinder 711 is provided on the lower side of the B positioning ring 72. The support cylinder 711 is connected to the upper side of the bottom ring 77. The support cylinder 711 positions the B positioning ring 72, thereby playing an auxiliary positioning role for the connection port 71 and improving the stability of the device. Water is discharged through the connection port 71 via a pipe that passes through the bottom ring 77. The bottom ring 77 provides support for the B connecting pipe 76 and the B mounting ring 75 for components such as the outer casing 1. When in use, the device is supported on a bracket. When not in use, the connection port 71 can be separated from the pipe, and the device can be placed directly on a flat surface for convenient use. The bottom ring 77 has a C mounting groove on its lower side. A protective plate 78 is installed inside the C mounting groove by a snap fastener. A protective block 79 is provided on the lower side of the water outlet pipe 3. The protective block 79 is detachably connected to the inner side of the connection port 71 by a snap fastener.

The lower side of the protective plate 78 has a through hole and the lower side of the protective block 79 has an auxiliary hole. An auxiliary block 712 is connected to the inner side of the through hole. When the device is not in use, the protective ring 710, the protective block 79 and the protective plate 78 are installed from the bottom side, which can seal the opening of the bottom ring 77 and protect the connection port 71, the water outlet pipe 3 and other components, reduce the probability of dust entering, and improve the safety and service life of the device. The PP cotton filter element 4 has a corrosion-resistant ceramic filter layer 9 on the outside, a granular activated carbon layer 10 connected to the outside of the corrosion-resistant ceramic filter layer 9, a nanofiber silver-loaded adsorption layer 11 connected to the outside of the granular activated carbon layer 10, a hollow fiber ultrafiltration membrane filter element 12 on the outside of the nanofiber silver-loaded adsorption layer 11, and a nanofiber membrane layer 13 connected to the outside of the hollow fiber ultrafiltration membrane filter element 12. The corrosion-resistant ceramic filter layer 9, the granular activated carbon layer 10, and the nanofiber silver-loaded adsorption layer 11 constitute the adsorption filter element, while the hollow fiber ultrafiltration membrane filter element 12 and the nanofiber membrane layer 13 constitute the main filter element. A connecting ring 5 is connected to the lower side of the corrosion-resistant ceramic filter layer 9, the granular activated carbon layer 10, and the nanofiber silver-loaded adsorption layer 11. A sealing ring 14 is located on the upper side of A connecting ring 5, and A sealing ring 14 is connected to the upper side of the corrosion-resistant ceramic filter layer 9, the granular activated carbon layer 10, and the nanofiber silver-loaded adsorption layer 11. A sealing ring 15 is located on the outer side of A sealing ring 14. An inlet pipe 17 is detachably located on the inner side of A sealing ring 14, and the inlet pipe 17 is connected to the upper side of the PP cotton filter element 4. Liquid enters the PP cotton filter element 4 through the inlet pipe 17. Pre-filtration intercepts large particles, extending the lifespan of the adsorption filter and main filter. Then, the liquid passes through the adsorption filter, where a corrosion-resistant ceramic filter layer 9 reduces the corrosive effect of the liquid on subsequent filter elements. The granular activated carbon layer 10 and the nanofiber silver-loaded adsorption layer 11 adsorb organic matter, residual chlorine, and heavy metals, preventing these substances from forming biofilms or chemical scale on the surface of the subsequent main filter membrane. Simultaneously, the nanofiber silver-loaded adsorption layer 11 sterilizes and disinfects the liquid using silver ions. Finally, after passing through the main filter, the liquid flows into the outer casing 1 and is discharged through the outlet pipe 3 for use. Hollow fiber ultrafiltration membrane filter element 12 is a highly efficient and compact liquid filtration technology widely used in medical, water treatment and biopharmaceutical fields. It consists of thousands of hollow fiber filaments with diameters of 0.5-2mm and wall thicknesses of 20-200μm, encapsulated in parallel in a pressure-resistant shell to form a "hair bundle" structure. Due to the pore size of the membrane surface of 1-50nm, it can retain substances with molecular weights of 1-300kDa, such as bacteria, viruses and proteins, through a sieving effect. In addition, some membrane materials are negatively charged, which can block pollutants with the same charge through electrostatic repulsion. The nanofiber membrane layer 13 can effectively prevent secondary pollution. The nanofiber diameter is usually between 50-500nm. It is formed into a dense three-dimensional network structure through electrospinning and other processes. This allows the small amount of pollutants passing through the hollow fiber ultrafiltration membrane filter element 12 to be adsorbed at the fiber intersections or embedded in the network pores, rather than just remaining on the surface, reducing the re-release caused by flow rate fluctuations. The outer shell 1, the main filter element, and the adsorption filter element all have corresponding positioning rings, making the filter elements more stable when they are fitted together. A limiting ring 16 is provided on the lower side of sealing ring 15. A limiting ring 16 is connected to the inner side of housing 1. A through hole is provided on the upper side of cover 2. Liquid inlet pipe 17 can slide inside the through hole. The mounting and positioning part 6 is located between the A sealing ring 14, the B sealing ring 15 and the upper cover 2. The mounting and positioning part 6 is used to install and position the PP cotton filter element 4, the corrosion-resistant ceramic filter layer 9, the granular activated carbon layer 10, the nanofiber silver-loaded adsorption layer 11, the hollow fiber ultrafiltration membrane filter element 12 and the rice fiber membrane layer. The mounting and positioning unit 6 includes an A positioning ring 61, a C sealing ring 62 on the upper side of a B sealing ring 15, a C sealing ring 62 connected to the upper side of an A sealing ring 14, an inlet pipe 17 detachably connected to the inner side of a C sealing ring 62, a B limiting ring 63 on the upper side of a C sealing ring 62, and a B limiting ring 63 connected to the outer side of an inlet pipe 17. During installation, the main filter element is first installed on the A limiting ring 16 through the B sealing ring 15, and then the adsorption filter element is installed inside the main filter element with the help of the C sealing ring 62 and the A sealing ring 14. Then, the PP cotton filter element 4 and the inlet pipe 17 are installed on the C sealing ring 62, the A sealing ring 14 and the inner side of the adsorption filter element. Through sealing rings and other means, the B sealing ring 15, the C sealing ring 62 and the A sealing ring 14 are sealed with the B limiting ring 63, separating the PP cotton filter element 4, the adsorption filter element and the main filter element to avoid mixing. An A contact ring 64 is provided on the outer side of the B limiting ring 63, and a B contact ring 65 is provided on the upper side of the B limiting ring 63. An adjusting cylinder 66 is connected to the upper side of the A contact ring 64. The adjusting cylinder 66 is connected to the outer side of the A positioning ring 61 through threaded engagement. The A positioning ring 61 is connected to the lower side of the upper cover 2. A B connecting ring 67 is provided on the lower side of the A positioning ring 61. The B connecting ring 67 is connected to the upper side of the B contact ring 65 and the inner side of the adjusting cylinder 66. An auxiliary ring 68 is provided on the inner side of the A positioning ring 61. The auxiliary ring 68 is connected to the lower side of the upper cover 2 and is connected to the outer side of the liquid inlet pipe 17. The PP cotton filter element 4, adsorption filter element, and main filter element are detachably connected via threads. After installation, the top cover 2 is installed on the outer casing 1 through the A connecting pipe 8. This allows the A positioning ring 61, along with the adjusting cylinder 66 and the B connecting ring 67, to move downwards. This causes the A contact ring 64 and the B contact ring 65 to press against the C sealing ring 62 and the B limiting ring 63, respectively. This secures the PP cotton filter element 4, adsorption filter element, and main filter element after installation, preventing any displacement and improving the efficiency of installation and disassembly. It also facilitates subsequent filter element replacement. An A mounting ring 69 slides on the outside of the inlet pipe 17. The A mounting ring 69 is connected to the upper side of the top cover 2. A protective cover 610 is provided on the upper end of the outside of the A mounting ring 69. The protective cover 610 is detachably connected to the outside of the A mounting ring 69 by a buckle. The protective cover 610 will protect the inlet pipe 17 when it is not in use, thereby improving the safety and service life of the device.
