[0002] Dialysis is a medical treatment method used to help the human body remove waste and excess fluid from the blood while maintaining the body's chemical balance. This treatment is usually used for patients with renal failure because their kidneys cannot effectively filter the blood and remove the toxins and excess water accumulated in the body. A dialysis water treatment device is often used during dialysis. The dialysis water treatment device is an important device for dialysis treatment and is mainly used to prepare pure water for dialysis. The water treatment device for a home hemodialysis machine with the publication number CN209052516U discloses a water treatment device including a housing, and five layers of filtering devices are arranged in the housing from top to bottom; the first layer, the second layer, the third layer and the fifth layer of filtering devices are all circular stainless steel electrode plates that fit the cylindrical housing; the fourth layer of filtering device is a circular boron-doped diamond thin film electrode plate that fits the cylindrical housing; activated carbon filtering devices are arranged on the surfaces of the stainless steel electrode plates of the first layer and the fifth layer of filtering devices; an ultrafiltration device is arranged between the first layer and the second layer of filtering devices; a reverse osmosis device is arranged between the second layer and the third layer of filtering devices; the concentrated liquid generated by the reverse osmosis device and the concentrated liquid generated by the ultrafiltration device flow out from the concentrated liquid outlet arranged in the middle position of the housing; the liquid passing through the reverse osmosis device flows to the circular stainless steel electrode plate of the third layer of filtering device; a purified water outlet is arranged at the bottom of the housing. This device has a simple structure and is convenient to use. However, the filtering components on this device are not provided with a disassembly mechanism, resulting in the inability to disassemble and maintain the filtering components when they are blocked, and the inability to disassemble and maintain will reduce the filtering effect of the filtering components on the dialysis water. This device still has deficiencies and needs to be improved. Summary of the Utility Model

Two turning handles 15 are symmetrically and fixedly installed on the outer wall of one end of the lead screw 12. By rotating the turning handle 15, it drives the lead screw 12 to rotate inside the fixing plates 10. During the rotation of the lead screw 12, it drives the regulating plate 13 to slide on the outer wall of the limiting round rods 11. During the sliding of the regulating plate 13, it drives the limiting insertion plate 14 to slide inside the limiting groove 9. After sliding a certain distance, the limiting insertion plate 14 will release the restriction on the connecting plate 8. After release, then pull the handle 16. By the handle 16, it drives the connecting plate 8 to move. During the movement of the connecting plate 8, it drives the insertion frame 6 to slide inside the sliding groove 5. During the sliding of the insertion frame 6, it drives the filter element body 7 to move together. After moving a certain distance, the filter element body 7 can be taken out for maintenance. This structure can quickly disassemble the filter element body 7, thereby facilitating the operator to maintain it, effectively avoiding that the inability to disassemble and maintain the filter element body 7 will reduce the filtering effect of the dialysis water.

[0024] Please refer to Figures 1-3 , the lead screw 12 is connected to the fixing plates 10 through bearings. The connection through bearings improves the rotation effect of the lead screw 12. The regulating plate 13 is slidably connected to the limiting round rods 11. The sliding connection improves the limiting effect during the adjustment of the regulating plate 13.

[0025] Embodiment Two

[0026] Please refer to Figure 4, a fixing ring 19 is fixedly installed on the outer wall of the drain pipe 3. The outer wall of the bottom end of the drain pipe 3 is threadedly connected with a connecting sleeve 20. A filter net 21 is fixedly installed inside the connecting sleeve 20. The secondary filtration effect of the dialysis water is improved through the filter net 21. At the same time, when the filter net 21 is blocked, the connecting sleeve 20 can be rotated to make the connecting sleeve 20 rotate on the outer wall of the drain pipe 3. After rotating a certain number of turns, the connecting sleeve 20 and the filter net 21 inside it can be removed together, thereby facilitating the operator to clean the blocked filter net 21, effectively avoiding that the blocked filter net 21 cannot be disassembled and cleaned, which will reduce the secondary filtration effect of the dialysis water. Anti-slip grooves 22 are evenly arranged on the outer wall of the connecting sleeve 20, and the anti-slip effect when rotating the connecting sleeve 20 is improved through the anti-slip grooves 22.

[0027] Working principle: When in use, first, the dialysis water is conveyed from the water inlet pipe 2 to the inside of the treatment tank 1. The conveyed dialysis water will flow onto the filter element body 7. After flowing onto it, the filter element body 7 will perform a primary filtration on the dialysis water. The dialysis water after the primary filtration will flow into the drain pipe 3, and then flow from the drain pipe 3 to the filter net 21 inside the connecting sleeve 20. After flowing onto it, the filter net 21 will perform a secondary filtration on the dialysis water after the primary filtration. When the filter net 21 is blocked, the connecting sleeve 20 can be rotated to make the connecting sleeve 20 rotate on the outer wall of the drain pipe 3. After rotating a certain number of turns, the connecting sleeve 20 and the filter net 21 inside it can be removed together, thereby facilitating the operator to clean the blocked filter net 21, effectively avoiding that the blocked filter net 21 cannot be disassembled and cleaned, which will reduce the secondary filtration effect of the dialysis water. When the filter element body 7 needs to be maintained, first rotate the turning handle 15. The turning handle 15 drives the lead screw 12 to rotate inside the fixing plate 10. During the rotation of the lead screw 12, it will drive the adjusting plate 13 to slide on the outer wall of the limiting round rod 11. During the sliding of the adjusting plate 13, it will drive the limiting insertion plate 14 to slide inside the limiting groove 9. After sliding a certain distance, the limiting insertion plate 14 will release the restriction on the connecting plate 8. After releasing, pull the handle 16. The handle 16 drives the connecting plate 8 to move. During the movement of the connecting plate 8, it will drive the insertion frame 6 to slide inside the sliding groove 5. During the sliding of the insertion frame 6, it will drive the filter element body 7 to move together. After moving a certain distance, the filter element body 7 can be taken out for maintenance.
