The skate plate 24 can be used to replace the filter cartridge 1 of different lengths by stretching or compressing the first spring 25; the water flow of the flow pipe 12 is in the push of the multi-electric push rod 43, the water flow can be enabled by the filter element 1. External diffusion, and water within the drawing tube 12 is driven by the multi-elevation push rod 43, thereby causing a guide tube The water in the 12 generates thrust to the curved plate 7, so that the curved plate 7 is deformed and depressed in the direction of the pressure sensor 6, but the thrust of the water flow is limited, so that the deformable curved plate 7 does not contact the pressure sensor 6, until The lead screw 56 is in contact with the curved plate 7, the screw 56 pushes the arcuate plate 7 that is deformed again, and is recessted to the direction of the pressure sensor 6 until the curved plate 7 is in contact with the pressure sensor 6; the pressure sensor 6 issues an electrical signal to The controller allows the controller to control the multi-piece electric push rod 43; after the operation, the controller controls the clean water port 42 and the inlet port. At this time, the water outlet is opened, and the remaining wastewater remaining from the outlet in the filter cartridge 3, control The multi-thrill rod 43 is controlled downward, so that the plurality of electric push rod 43 pushes the remaining water to clean the filter element 1, so that the bacterial and mineral metal particles of the filter die 1 are left by the remaining water flow 1 filter 1 filter element 1 The surface layer flows to the upper end of the filter element 2, brushing the bacteria and mineral metal particles on the upper end of the filter element 2 to the second annular groove 26, and finally flowing out from the liquid push rod 43; multi-section electric push rod 43 The screw 56 elongates downward, so that the ring sleeve 55 is rotated by rotating the filter element 1 such that the antibacterial activated carbon rod 112 in the chute 111 continues to stretch the three spring 113 under the action of centrifugal force, and to the second one-way valve 114 The direction slides so that a part of the water flow in the drawing tube 12 flows into the antibacterial activated carbon rod 112 and the flow of the fluid tube 12, since the filter layer 11 is wound on the guide tube 12, thereby forming a filter layer 11, and pair The tap water is filtered layer filtration, so it is easy to store bacterial and mineral metal particles between the adjacent two-layer reverse osmosis membranes; the water flow in the drawing tube 12 is promoted under the push of the multi-electric push rod 43, and a portion of the water flow can be promoted. Bacteria and mineral metal particles in the filter layer 11 are smaller than the outermost surface of the filter layer 11 to the filter layer 11, and the other portion of the water stream can push the volume of bacteria and mineral metal particles that are blocked by the filter element. A large portion flows downward from two adjacent filter layers 11 until reaches the chute 111 because the antibacterial activated carbon rod 112 can inhibit bacterial attachment and reproduction, so the water flow flowing into the chute 111 can be followed by antibacterial activated carbon. The rod 112 brushes the bacteria from the second one-way valve 114, when the filter cartridge 1 stops the rotation of the three spring 113 to restore the antibacterial activated carbon rod 112 away from the second one-way valve 114, and is located in the antibacterial activated carbon rod 112 and guide flow The water filtered between the tube 12 was subjected to the squeeze of the antibacterial activated carbon rod 112, and partially flowed into the filter layer 11 adjacent the guide pipe 12, so that the filtered water is cleaned up close to the filter layer 11 near the guide pipe 12, and the other Flowing from the 2nd one-way valve 114 in accordance with the antibacterial activated carbon rod 112, and rinsing the surface of the antibacterial activated carbon rod 112, during the process of tap water filtration, the second one-way valve 114 blocks the tap water into the chute 111, and The filter layer 11 layer filtered water enters the chute 111 to be filtered again by the antibacterial activated carbon rod 112.
