A cleaning component is arranged on the support rod 26, and a conveying component is arranged on the top of the reverse osmosis filter bottle 37. When the reverse osmosis water purification equipment is used to filter and purify the water source, the water source to be treated will enter the interior of the primary filter component through the water inlet pipe 4, and the water source will be carried by the primary filter component. The impurities are filtered and processed, and the water source that has been initially filtered is transmitted by the pressure pump 5, so that the water source is transmitted to the filter component. After being filtered again by the filter component, the water source will flow into the water flow trough 8. After the water source enters the water flow trough 8, it will push the No. 1 driving blade 27 to rotate. At the same time, when the water source flows to the reverse osmosis filter element 34, it will push the No. 2 driving blade 28 to rotate. When the No. 1 driving blade 27 and the No. 2 driving blade 28 rotate, the rotating shaft 22 will rotate. When the rotating shaft 22 rotates, it will drive the cleaning component to move.

After the water source is filtered by the filter element 7, the water source will flow to the pressure pump 5 through the connecting pipe 6. The pressure pump 5 can transmit the water source when it is working.

The water source can be further filtered. The sealing plate 10 is fixedly connected to the concave groove 9 by bolts. A sealing ring is arranged on the sealing plate 10 to seal and protect the connection with the concave groove 9. When the impurities filtered by the filter plate 13 are removed, the concave groove 9 is no longer sealed after the sealing plate 10 is disassembled, and then the filter plate 13 is pulled. Through the cooperation of the card slot 12, the filter plate 13 can be pulled to the outside, and then the filter plate 13 can be disassembled and cleaned, thereby improving the cleaning efficiency.

[0037] like Figure 5 As shown, a conical groove 14 is fixedly connected to the bottom of the concave groove 9, an L-shaped bracket 15 is fixedly installed at the bottom of the conical groove 14, guide rods 16 are arranged in an array on the L-shaped bracket 15, and a limit ring 17 is arranged around the guide rod 16.

The conical groove 14 provides an installation space for the L-shaped bracket 15, and the L-shaped bracket 15 provides an installation space for the guide rod 16. The guide rod 16 is used to guide the limit ring 17 so that the limit ring 17 moves smoothly.

[0038] like Figure 5As shown, a support plate 18 is fixedly installed on the limit ring 17, and a sealing block 20 corresponding to the conical groove 14 is fixedly installed on the top of the support plate 18, and the top of the sealing block 20 extends to the inside of the conical groove 14, and a flow channel 21 is arranged inside the sealing block 20.

The L-shaped bracket 15 provides an installation space for the reset spring 19. When the conical groove 14 discharges water, the water source exerts pressure on the sealing block 20, so that the sealing block 20 moves downward and drives the flow channel 21 to move out of the conical groove 14, and then the water source improves the flow channel 21 to flow into the water flow trough 8. When the water source is stopped, the reset spring 19 is reset, which will push the support plate 18 to move, and then the sealing block 20 will re-enter the conical groove 14 to seal the flow channel 21, thereby avoiding water backflow.

[0039] like Figure 3 As shown, the guide assembly includes a guide ring 24 and an annular groove 25. The annular groove 25 is fixedly installed inside the water flow channel 8. The guide ring 24 is engaged in the annular groove 25, and the top of the guide ring 24 is fixedly connected to the bottom of the turntable 23. When the sealing block 20 moves, it will drive the support plate 18 to move. When the turntable 23 rotates, it will drive the guide ring 24 to rotate inside the annular groove 25. The cooperation between the guide ring 24 and the annular groove 25 will make the turntable 23 rotate smoothly, thereby guiding the turntable 23.

[0040] like Figure 6 As shown, the cleaning assembly includes a positioning ring 29, a support block 30, a strip plate 31 and a storage assembly. The positioning ring 29 is arrayed on the support rod 26, the support block 30 is fixedly mounted on the positioning ring 29, the strip plate 31 is fixedly mounted on the support block 30, and the storage assembly is arranged on the strip plate 31.

[0041] like Figure 8 As shown, the storage assembly includes a cleaning plate 32 and a storage groove 33. The cleaning plate 32 is fixedly mounted on the strip plate 31, and one side of the cleaning plate 32 is in contact with the inner wall of the reverse osmosis filter element 34. The storage groove 33 is arranged on the cleaning plate 32. When the strip plate 31 makes a circular motion, it will drive the cleaning plate 32 to move. When the cleaning plate 32 moves, the adsorbent on the inner wall of the reverse osmosis filter element 34 will be scraped off, thereby effectively avoiding excessive adsorbent on the inner wall of the reverse osmosis filter element 34, which will cause blockage. The scraped impurities will fall into the water trough 8. A sewage pipe is arranged on the side of the water trough 8. When the impurities falling into the water trough 8 are removed, the water source is made to flow into the water trough 8 to flush the impurities, and the removed impurities will be discharged to the outside through the sewage pipe.

The drain pipe 35 is installed at the top of the reverse osmosis filter bottle 37, and the water pipe 36 is installed at the top of the drain pipe 35. The water pipe 36 is connected to an external water storage tank. The water source filtered by the reverse osmosis filter bottle 37 will flow into the drain pipe 35, and the water source will flow into the water pipe 36 through the drain pipe 35. The water source will flow into the external water storage tank for storage through the water pipe 36, thereby achieving the purpose of filtering and collecting the water source.

[0043] Working principle: First, when using the reverse osmosis water purification equipment to filter and purify the water source, the water source enters the filter element 7 through the water inlet pipe 4. After the water source is filtered by the filter element 7, the water source will flow to the pressure pump 5 through the connecting pipe 6. The pressure pump 5 can transmit the water source when it is working. The water source drawn by the pressure pump 5 will flow into the concave groove 9 through the delivery pipe 11, and then the water source will flow through the filter plate 13, and the water source can be further filtered and processed, and then the water source will enter the conical groove 14 for transmission. When the conical groove 14 discharges water, the water source applies pressure to the sealing block 20, causing the sealing block 20 to move downward and drive the flow channel 21 to move out of the conical groove 14, and then the water source increases the flow channel 21 and flows into the water flow groove 8. When the water source is stopped, the reset spring 19 is reset, which will push the support plate 18 to move, and then the sealing block 20 will re-enter the conical groove 14 to seal the flow channel 21, thereby preventing the water source from flowing back. When the water source enters the water flow groove 8, it will push the No. 1 driving blade 27 to rotate, and the water source flow When the reverse osmosis filter element 34 is moved, the second driving blade 28 will be pushed to rotate. When the first driving blade 27 and the second driving blade 28 rotate, the rotating shaft 22 will be rotated. When the rotating shaft 22 rotates, the cleaning component will be driven to move. The movement of the cleaning component will scrape the adsorbed material on the inner wall of the reverse osmosis filter element 34, thereby avoiding excessive adsorption of the adsorbed material on the reverse osmosis filter element 34 to cause blockage. The reverse osmosis filter element 34 needs to be cleaned frequently to improve the efficiency of water purification. The water source filtered by the reverse osmosis filter bottle 37 will flow into the drain pipe 35, and the water source will flow into the water pipe 36 through the drain pipe 35. The water source will flow into the external water storage tank for storage through the water pipe 36, thereby achieving the purpose of filtering and collecting the water source, and then achieving the purpose of storing the filtered water source. Impurities, pollutants and dissolved solids in the water are removed by the reverse osmosis filter element 34, thereby providing purer water. The semi-permeable membrane principle is used to press water molecules into one side of the membrane to prevent larger molecules and ions from passing through, thereby achieving water purification.
