[0002] Reverse osmosis pure water device is a water treatment equipment. The reverse osmosis membrane in the equipment can prevent solutes, bacteria, viruses and other particles from passing through, and only allow water molecules to pass through.

Then, the first motor 7 is started, and its output end drives the rotating handle 8 to rotate at the bottom of the support seat 6. At this time, the rotating handle 8 and the second motor 9 connected to one end rotate, so that the second motor 9 drives the sprayer 10 to revolve. At the same time, the power of the second motor 9 is also transmitted to the connecting column 13 connected to the outer wall, so that the connecting column 13 rotates inside the support frame 12. In this process, the connecting column 13 is subjected to force to drive the internal connecting frame 11 of the support frame 12 to rotate, and finally the sprayer 10 can realize rotation at different angles inside the filter tank 2, thereby realizing uniform cleaning of the inside of the filter tank 2.

[0036] Reference Figure 1 , Figure 5 and Figure 6 The connecting assembly includes a first connecting frame 14 and a second connecting frame 15, one side of the first connecting frame 14 is fixedly connected to the outer wall of the sealing cover 4, one side of the second connecting frame 15 is fixedly connected to the outer wall of the filter tank 2, the first connecting frame 14 is slidably connected to the inside of the second connecting frame 15, the first connecting frame 14 is rotatably connected to the inside of the first connecting frame 14, the second connecting frame 15 is rotatably connected to the inside of the second connecting frame 15, the first clip 16 and the second clip 17 are in contact, the filter tank 2 and the outer wall of the sealing cover 4 are fixedly connected with positioning blocks 22, one of the positioning blocks 22 is fixedly connected with a bolt 23, the other positioning block 22 is slidably connected to the outer wall of the bolt 23, and the outer wall of the bolt 23 is threadedly connected with a nut 24.

[0037] Specifically, when the activated carbon plate 5 inside the filter tank 2 needs to be maintained or replaced, first, the nut 24 is screwed off to release it from the bolt 23, and then the lever 18 is toggled to remove the first connection frame 14 from the second connection frame 15, so that the positioning block 22 on the outer wall of the sealing cover 4 can be removed from the bolt 23. After the replacement of the activated carbon plate 5 is completed, the positioning block 22 on the outer wall of the sealing cover 4 is firstly sleeved on the outer wall of the bolt 23, and then the first connection frame 14 will smoothly slide into the second connection frame 15. In this process, the first buckle 16 inside the first connection frame 14 will be limited by the second connection frame 15, so that it rotates; and the second buckle 17 inside the second connection frame 15 is also limited by the first connection frame 14 and rotates at the same time, so that the first buckle 16 and the second buckle 17 form a parallel state, so that the first connection frame 14 can smoothly slide into the second connection frame 15, and the sealing cover 4 and the filter tank 2 are quickly positioned and connected.

[0038] Reference Figure 1 , Figure 5 and Figure 6 The outer walls of the first buckle 16 and the second buckle 17 are fixedly connected with a lever 18, the lever 18 is rotatably connected to the inside of the first connecting frame 14 and the second connecting frame 15, one side of the lever 18 is fixedly connected to a connecting block 19, the first connecting frame 14 and the second connecting frame 15 are fixedly connected with a fixing column 21, the outer wall of the fixing column 21 is sleeved with a spring 20, and one end of the spring 20 is fixedly connected to the inside of the connecting block 19.

[0039] Specifically, at the same time, the first buckle 16 and the second buckle 17 will drive the lever 18 connected to the outer wall to rotate, and the lever 18 is subjected to force to cause the connecting block 19 to move. The connecting block 19 contracts by squeezing the spring 20 connected inside. When the first connecting frame 14 completely slides into the second connecting frame 15, the spring 20 unloads the force and rebounds to reset the connecting block 19. This makes the first buckle 16 and the second buckle 17 driven by the lever 18 return to their original positions, in an inclined state and engaged with the first connecting frame 14 and the second connecting frame 15.

After the replacement of the activated carbon plate 5 is completed, the positioning block 22 on the outer wall of the sealing cover 4 is sleeved on the outer wall of the bolt 23, and at the same time, the first connecting frame 14 on the outer wall of the sealing cover 4 will slide into the second connecting frame 15, in this process, the first buckle 16 inside the first connecting frame 14 will be limited by the inside of the second connecting frame 15, and then rotate, and the second buckle 17 inside the second connecting frame 15 will be limited by the first connecting frame 14 and also rotate, at this time, the second buckle 17 and the first buckle 16 rotate in a parallel state, so that the first connecting frame 14 can slide smoothly into the second connecting frame 15, and at the same time, the first buckle 16 and the second buckle 17 will drive the lever 18 connected to the outer wall to rotate, and the lever 18 is forced to drive the connecting block 19 to move, and the connecting block 19 is forced to squeeze the spring connected inside. 20, so that it shrinks. When the first connecting frame 14 completely slides into the second connecting frame 15, the spring 20 unloads the force and rebounds, thereby driving the connecting block 19 to reset, so that the lever 18 drives the first buckle 16 and the second buckle 17 to be turned back to the original position in an inclined state, so that it is stuck in the first connecting frame 14 and the second connecting frame 15, so that the sealing cover 4 and the filter tank 2 are quickly positioned and connected. After the connection is completed, the nut 24 is connected to the outside of the bolt 23 and stuck on the positioning block 22 on the outer wall of the sealing cover 4, so that the filter tank 2 and the sealing cover 4 are further reinforced, so that the activated carbon plate 5 is easy to replace and maintain.
