The filter layer 11 of the filter element 1 is turned off, and the filtered water flow can be entered into the inside of the guide tube 12 by the permeation hole, and the bacteria and mineral metal particles in the water are blocked by the filter layer 11. In the surface of the filter element 1, as the water filtered in the flow of the flow, the water flows in the drawing tube 12 flows from the through hole 51 to the pump 5, and then the water hole 54 on the side wall of the packet 5 Flow, the water filtered through the No. 1 annular groove 41, finally flows out from the clean water port 42; after the operation, the controller controls the clean water port 42 and the inlet port, at which time the water opening is opened, the filter cartridge 3 remains The wastewater flows out of the water, since the clean water port 42 is closed, and the water flow tube 12 is filled with water, and the packet 5 is in a regulated state, and the water filtered in the packet 5 does not flow from the one-way valve 53. At this time, the controller controls the multi-thrill rod 43, and the first step of the plurality of electric push rod 43 will enter the through hole 51 to the guide pipe 12, so that the plurality of electric push rod 43 The rod pushes the water flow to the surface of the guide tube 12, so that the water purification of the filtered water in the drawing tube 12 is filtered, and the filtered water water can be provided with bacteria and mineral metal attached to the surface of the filter layer 11. Particles, the second pole of the electric push rod pushes the water in the pressure plate 44 inserted into the groove 5, so that the water within the groove 5 is discharged from the one-way valve 53 and ejected from the inclined hole 52 because the oblique hole 52 is facing Near one end of the filter element 1 toward the surface of the filter layer 11 of the filter element 1, the water in the packet 5 is sprayed from the surface of the filter element 11 of the flux hole 52, and when the plurality of electric push rod 43 pushes the pressure plate 44 When in the bottom of the pneumatic 5, the lower end of the plurality of electric push rod 43 is in contact with the upper end of the filter, at which time the controller controls the multi-piece electric push rod 43; when the filter element 1 needs to be replaced, the user The filter holder 2 is rotated such that the filter element 2 is rotated, and when the filter 2 is partially separated from the bottom portion of the filter cartridge 3, the filter element 5 is rotated and separated, and then the filter element 1 needs to be replaced on the filter element 2 Next, the new filter element 1 is installed, and the filter cartridge 1 extends into the filter cartridge 3, and the filter base 2 is rotated, so that the filter element 2 is simultaneously rotated, thereby so that the filter element 1 is mounted on the concave block 5; controller control more The electric push rod 43 elongates downward such that the lead screw 56 can extend into the ring sleeve 55 such that the ring sleeve 55 constitutes a lead bar 56 nut, and with the plurality of electric push rod 43 push the wire The bar 56 moves downward such that the ring sleeve 55 rotates along the central axis of the lead screw 56, since the ring sleeve 55 is threaded with the guide tube 12, and the rotation block 21 is rotated to the filter holder 2, so the ring cover 55 is rotated. The ring sleeve 55 can rotate by rotating the filter element 1 such that the filter element 1 can rotate on the filter element 2 when the filter element 1 is rotated, and the multi-piece electric push rod 43 pushes the lead screw 56 and the one slide 22 slot.
