[0035] Both ends of the hose 6 are fixedly connected with metal pipes, and the two ends of the hose 6 are respectively connected to the top of the water tank 5 and the bottom of the water collection tank 1 through the metal pipes, and a second pump body 13 is provided at the metal pipe on one side of the hose 6 close to the water collection tank 1;

[0036] The filter element structure 12 includes an upper cylinder 14, a fine-pore filter cylinder 15 is fixedly installed at the bottom of the upper cylinder 14, a bottom plate 16 is fixedly installed at the bottom of the fine-pore filter cylinder 15, a sealing ring 17 is fixedly sleeved on the outer wall of the top of the upper cylinder 14, and the outer wall of the top of the upper cylinder 14 is in sliding contact with the inner wall of the through hole 3 through the sealing ring 17, and a lifting rod 18 is fixedly installed on the inner wall of the middle part of the upper cylinder 14;

[0038] See also Figure 1 A pure water conduit 20 is fixedly sleeved at the center position of the top of the water tank 5, and a control valve is provided at one end of the pure water conduit 20 close to the water tank 5, wherein a drain pipe (not shown in the figure) is fixedly sleeved on one side of the bottom end of the water collecting pool 1, and a valve is provided on the drain pipe. By setting the drain pipe and the valve, the water source that is circulated between the water tank 5 and the water collecting pool 1 can be effectively discharged after being used for a long time, thereby facilitating the placement of a new pure water source for flushing in the water tank 5.

[0039] The implementation principle of this embodiment is as follows: before use, the whole is in a complete assembly state, and the external pure water output pipe, the pure water conduit 20 on the top of the water tank 5, and the control valve are used to collect a sufficient amount of water source for flushing the ultrafiltration membrane inside the water tank 5, wherein the length of the hose 6 itself is not limited to the state shown in the drawings, and can be used to adjust the height of the water tank 5 by the vertical cylinder 4, so as to deform and extend itself;

Before the flushed sewage flows into the inside of the water collecting tank 1, it is filtered by the fine-pore filter cartridge 15 in each filter element structure 12. The filtered water source inside the bottom end of the water collecting tank 1 is redirected to the inside of the water tank 5 through the hose 6 and the second pump body 13, thereby realizing the recycling of the water source used for flushing.

[0042] After flushing is completed, each ultrafiltration membrane body 11 can be extracted by lifting the water tank 5, and then the next round of ultrafiltration membrane body 11 flushing operation can be carried out. During this process, when necessary, the filter element structure 12 can be extracted as a whole by manually extracting the lifting rod 18, thereby facilitating the cleaning operation of impurities filtered inside the fine-pore filter cartridge 15.
