[0025] like Figure 1 , Figure 2 A water-saving reverse osmosis membrane pure water device is shown, and the embodiment of the present application provides, comprising a tank body 1 and a water inlet pipe 101, characterized in that a partition plate 102 is installed in the middle of the interior of the tank body 1, a filter membrane 103 is clamped on the inner bottom side of the tank body 1, a water outlet pipe 104 parallel to the outer wall of the filter membrane 103 is arranged at the bottom of the tank body 1, a baffle plate 2 is installed at the bottom center of the tank body 1, a hollow vertical rod 201 is installed on the top of the baffle plate 2, a slidable recoil pipe 3 is arranged on the top of the vertical rod 201, a spray hole is opened in the middle of the outer wall of the recoil pipe 3, a water delivery pipe 301 is connected to the bottom of the recoil pipe 3, the recoil pipe 3 passes through the partition plate 102, and a screw rod 302 is connected at the center of the recoil pipe 3;

[0026] The partition plate 102 divides the internal cavity of the tank body 1 into an upper part and a lower part. One side of the water inlet pipe 101 is connected to an external pressure water source. By rotating the screw rod 302, the recoil pipe 3 can slide on the vertical rod 201 to control the relative position between the recoil pipe 3 and the partition plate 102. The water entering the tank body 1 passes through the center of the partition plate 102 and then enters the cavity formed by the filter membrane 103. The water inlet pressure is maintained by the external pressure water source to maintain a good filtering effect of the filter membrane 103.

[0027] When the backwash pipe 3 closes the through hole at the center of the partition plate 102, the external spray hole of the backwash pipe 3 is facing the contaminated surface inside the filter membrane 103. The contaminated surface of the filter membrane 103 can be flushed by sending cleaning liquid into the water pipe 301 through the external water supply equipment, thereby achieving a good cleaning effect. The backwash pipe 3 can prevent impurities from passing through the partition plate 102 to ensure the overall cleanliness of the system.

[0028] When the filter membrane 103 is backwashed by using the water outlet pipe 104 connected to an external water delivery device, the water outlet pipe 104 is not directly facing the filter membrane 103 to prevent the high-speed water flow from directly impacting the filter membrane 103 and reduce damage to the filter membrane 103.

[0029] In this embodiment, Figure 2-Figure 4 As shown; the end opening of the water outlet pipe 104 is located on the line between the filter membrane 103 and the tank body 1;

[0030] The end opening of the water outlet pipe 104 is arranged opposite to the partition plate 102 . When backwashing is performed using the water outlet pipe 104 , water can flow toward the partition plate 102 , thereby reducing the situation where the water directly impacts the filter membrane 103 .

[0031] A groove is provided at the bottom of the recoil pipe 3, and the recoil pipe 3 is sleeved on the end of the vertical rod 201 through the groove. A sealing ring is provided on the side wall of the groove at the bottom of the recoil pipe 3;

[0032] The recoil pipe 3 and the vertical rod 201 are guided by the groove, so that the recoil pipe 3 and the vertical rod 201 can move more accurately and stably in the vertical direction, thereby achieving a good sealing effect and suppressing external pollution and leakage.

[0033] The spray hole of the recoil pipe 3 is arranged in the middle of the outer side, and the diameter of the spray hole is smaller than the thickness of the partition plate 102;

[0034] When the outer spray hole of the recoil pipe 3 is located above the partition plate 102, the top surface of the partition plate 102 can be flushed. The outer spray hole of the recoil pipe 3 can also be closed by the partition plate 102 to stop the water inside the tank body 1 from flowing, thereby reducing the waste of water resources caused by the flow.

[0035] A key slot is provided on the outer wall of the vertical rod 201, and a protrusion is provided on the inner wall of the recoil tube 3 to be embedded in the key slot;

[0036] The cooperation between the keyway and the protrusion prevents the recoil tube 3 and the screw rod 302 from rotating synchronously, thereby ensuring the accuracy of the position adjustment of the recoil tube 3.

[0037] Two layers of filter screens 105 are arranged above the interior of the tank body 1, and activated carbon particles are filled between the two layers of filter screens 105;

[0038] The two-layer filter screen 105 has a good restraining and limiting ability for the activated carbon particles. The filter screen 105 has the effect of initially separating impurities, and the activated carbon particles can further absorb the impurities, thereby extending the service life of the filter membrane 103.

[0039] A limiting ring 106 is provided on the bottom side wall of the tank body 1, and the limiting ring 106 is sleeved on the bottom edge of the filter membrane 103;

[0040] The limiting ring 106 is used to position the filter membrane 103 to prevent the seal failure caused by the deformation and displacement of the filter membrane 103.
