[0029] Embodiment 1

[0030] This embodiment provides a resin filtering device, such as Figure 1 and 2 As shown, it comprises a housing 1, a resin filter element 2 is fixedly installed inside the housing 1, and a clean water outlet pipe 4 and a cleaning water inlet pipe 9 are connected to the side of the housing 1;

[0031] like Figure 3 and 4 As shown, a self-cleaning component 7 is provided on the side of the clean water outlet pipe 4, and the self-cleaning component 7 includes a water drain, a centrifugal block 74, a resistance spring 76, a ring 77 and a displacement sensor 79. The water drain includes a water drain rotating shaft 71 and a water drain blade 72. The water drain rotating shaft 71 passes through the inside of the clean water outlet pipe 4, and a plurality of water drain blades 72 distributed in an annular light angle are fixedly installed on the shaft body of the water drain rotating shaft 71. The water drain rotating shaft 71 and the clean water outlet pipe 4 are perpendicular to each other, and a block is fixedly installed inside the clean water outlet pipe 4. Water flows in the clean water outlet pipe 4, and the water impacts the water drain blade 72.

[0032] The block makes the water entering the purified water outlet pipe 4 only impact the water row blades 72 below the water row shaft 71, so that the water row shaft 71 and the water row blades 72 rotate. The rotation speed of the water row shaft 71 and the water row blades 72 represents the water flow speed.

[0033] like Figure 4 As shown, the water drain shaft 71 is located on the outer side of the clean water outlet pipe 4, and a circular guide rod 73 with equal angles is fixedly installed on the shaft body. The centrifugal block 74 slides on the rod body of the guide rod 73. A resistance spring 76 is elastically connected between the water drain shaft 71 and the centrifugal block 74. The centrifugal force is applied to the centrifugal block 74 through the rotation of the water drain shaft 71. The resistance spring 76 applies elastic force to the centrifugal block 74 to prevent it from sliding on the guide rod 73.

[0034] like Figure 4As shown, the end of the ring 77 is rotatably connected to the clean water outlet pipe 4, the end of the centrifugal block 74 is in contact with the ring 77, a displacement sensor 79 is provided on the outer arc surface of the clean water outlet pipe 4, the displacement sensor 79 faces the ring 77, and a clean water solenoid valve 8 is fixedly installed on the side of the clean water outlet pipe 4, and the displacement sensor 79 is electrically connected to the clean water solenoid valve 8 through a controller.

[0035] When the water flow speed in the purified water outlet pipe 4 is fast, the water discharge shaft 71 rotates and uses centrifugal force to move the centrifugal block 74. The centrifugal block 74 overcomes the elastic force of the resistance spring 76 and moves in the direction of the ring 77. The centrifugal block 74 squeezes the ring 77 and drives the ring 77 to rotate. The displacement sensor 79 detects the rotation of the ring 77, which indicates that the micropores on the resin filter element 2 are in an unblocked state.

[0036] When the water flow speed in the purified water outlet pipe 4 is slow, the centrifugal force of the water discharge shaft 71 on the centrifugal block 74 is smaller than the elastic force of the resistance spring 76. At this time, the centrifugal block 74 is separated from the ring 77, and the ring 77 is in a stationary state, indicating that the micropores on the resin filter element 2 are blocked.

[0037] like Figure 4 As shown, a docking tube 78 is fixedly installed on the side of the purified water outlet pipe 4, a displacement sensor 79 is fixedly installed on the docking tube 78, the end of the water discharge shaft 71 is rotatably connected to the docking tube 78, a limit block 75 is fixedly installed on the end of the guide rod 73, and the centrifugal block 74 adopts a U-shaped structure, and an arc surface structure is provided at the end of the centrifugal block 74, and the arc surface curvature of the end of the centrifugal block 74 is the same as the inner arc surface curvature of the circular ring 77. The U-shaped structure of the centrifugal block 74 avoids the limit block 75, and the limit block 75 limits the centrifugal block 74, and the end of the centrifugal block 74 is completely fitted with the circular ring 77 to increase the contact area.

[0038] In this embodiment, the water discharge shaft 71 is driven to rotate by the water flow, the micropores on the resin filter element 2 are blocked, and the water flow rate is slowly reduced. At this time, the centrifugal force on the centrifugal block 74 is less than the elastic force of the resistance spring 76, and the centrifugal block 74 is separated from the ring 77. The displacement sensor 79 detects that the ring 77 is stationary, so that the water purification solenoid valve 8 is closed, and water is introduced into the cleaning water inlet pipe 9. The cleaning water inlet pipe 9 is used to backwash the resin filter element 2, thereby realizing self-detection of blockage and timely backwashing.

[0039] Embodiment 2

[0040] like Figure 2 and 3 As shown, based on the first embodiment, this embodiment proposes a resin filtering device, a clean water inlet pipe 3 is fixedly installed on the top of the outer shell 1, a cleaning sewage pipe 5 is fixedly installed on the bottom of the outer shell 1, a sewage solenoid valve 6 is fixedly installed on the cleaning sewage pipe 5, and a displacement sensor 79 is electrically connected to the sewage solenoid valve 6 through a controller.

[0041] During self-cleaning, water enters the cleaning water inlet pipe 9, and the displacement sensor 79 closes the water purification solenoid valve 8 and opens the sewage discharge solenoid valve 6 through the controller, so that water enters to backwash the resin filter element 2, and the particles blocked in the micropores of the resin filter element 2 are flushed out by water pressure and discharged from the cleaning sewage discharge pipe 5.

[0042] In this embodiment, during cleaning, water is introduced into the cleaning water inlet pipe 9, and the resin filter element 2 is flushed with water to flush out the particles blocking the micropores on the resin filter element 2, and the sewage containing the particles is discharged from the cleaning sewage pipe 5, thereby increasing the service life of the resin filter element 2.

[0043] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
