Their structure and principle are common knowledge and can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0023] Example 1:

[0024] Please see Figures 1-6As shown, this utility model provides an externally mounted siphon, including a hollow tube 7. A fixed sleeve 1 is movably fitted onto the right end of the outer surface of the hollow tube 7. A flange 2 is fixedly connected to the left end of the outer surface of the fixed sleeve 1. A double-layer guide cover 4 is fixedly installed on the right end of the outer surface of the hollow tube 7, located to the right of the fixed sleeve 1. A rotating shell 3 is fixedly installed on the left side of the double-layer guide cover 4. A first bearing 17 and a second bearing 19 are fixedly installed sequentially from left to right between the inner cavity of the rotating shell 3 and the outer surface of the fixed sleeve 1. A sealing plug 8 is fixedly installed on the left side of the hollow tube 7. A through bolt 12 is movably inserted between the middle end of the sealing plug 8 and the middle end of the right side of the double-layer guide cover 4. The number of through bolts 12 is two. A horizontal siphon tube 16 is fixedly installed between the lower right end of the sealing plug 8 and the lower right end of the inner cavity of the double-layer guide cover 4. An outlet 14 is provided at the lower right end of the double-layer guide cover 4 and to the right of the horizontal siphon tube 16. A mating hole 26 is provided at the lower end of the sealing plug 8 and to the left of the horizontal siphon tube 16. A limiting pin 11 is movably inserted through the upper end of the sealing plug 8. A connecting seat 9 is fixedly installed at the middle end of the limiting pin 11. The surface of the connecting seat 9 contacts the left side of the sealing plug 8. Threaded holes 27 are provided at both ends of the right side of the connecting seat 9. The left end of the through bolt 12 is threaded to the surface of the threaded hole 27. An end siphon tube 10 is fixedly installed at the lower end of the inner cavity of the connecting seat 9.

[0025] In this technical solution, when it is necessary to install the siphon and the roller body, firstly, use a tool to rotate the two sets of through bolts 12 so that the left end of the through bolt 12 can be removed from the threaded hole 27 of the connecting seat 9. At this time, because the connecting seat 9 is not restricted by the through bolts 12, the personnel can push the end siphon tube 10 and the connecting seat 9 to drive the limiting pin 11 to rotate along the upper end of the sealing plug 8, so that the opening of the end siphon tube 10 can be disengaged from the left side of the docking hole 26 until the connecting seat 9 can be in a horizontal position. Then, the personnel can insert the end siphon tube 10, the connecting seat 9, the sealing plug 8 and the hollow tube 7 into the roller body from the opening on the side. After the hollow tube 7 is fully inserted into the roller body, the flange 2 can be installed on the side of the roller body with bolts. During the insertion of the end siphon tube 10 and the connecting seat 9 into the roller, under the action of gravity, the end siphon tube 10 and the connecting seat 9 can rotate downward, causing the end siphon tube 10 and the connecting seat 9 to rotate downward. The end of the siphon 10 can extend into the water inside the roller, while the threaded hole 27 is positioned to the left of the through bolt 12. Then, the operator can use a tool to rotate the through bolt 12, so that the through bolt 12 can be tightened into the threaded hole 27. This effectively installs and fixes the connecting seat 9 and the sealing plug 8, preventing the end siphon 10 and the connecting seat 9 from shaking during later use. This completes the overall installation. Since the overall installation can be performed outside the roller, it is convenient and quick to operate, and it greatly facilitates the subsequent disassembly and maintenance. When used later, by connecting the external water outlet pipe to the water outlet 14 and ensuring that the end of the water outlet pipe is lower than the end of the end siphon 10, the water inside the roller can be discharged along the end siphon 10, the connecting hole 26, the horizontal siphon 16, the water outlet 14, and the water outlet pipe under the action of the siphon principle.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a mounting hole is provided on the right side of the outer surface of the double-layer flow guide cover 4, an end cover 5 is provided on the right side of the double-layer flow guide cover 4, a mounting bolt 6 is movably inserted on the surface of the end cover 5, pipe mounting holes are provided at both ends of the end cover 5, an air inlet pipe 23 is fixedly installed between the upper right end of the sealing plug 8 and the upper right end of the inner cavity of the double-layer flow guide cover 4, an air inlet 13 is provided on the upper right end of the double-layer flow guide cover 4 and to the right of the air inlet pipe 23, an air inlet hole 24 is provided on the upper end of the sealing plug 8 and to the left of the air inlet pipe 23, a water inlet connector 15 is fixedly connected to the right end of the bottom of the double-layer flow guide cover 4, flow guide holes 21 are provided around the right end of the inner cavity of the double-layer flow guide cover 4, and a water inlet hole 25 is provided in the middle of the sealing plug 8.

[0028] In this technical solution, the installation holes and installation bolts 6 facilitate the assembly of the end cap 5 and the double-layer guide cap 4. The pipe installation holes facilitate the installation of external air supply pipes and drainage pipes, and allow connection with the air inlet 13 and water outlet 14. The air inlet pipe 23 and air inlet hole 24 enable the sealing plug 8 to connect with the double-layer guide cap 4 for air supply to the roller. The water inlet connector 15 enables connection with the external water inlet pipe. Under the action of the guide hole 21, hollow pipe 7 and water inlet hole 25, the sealing plug 8 can connect with the water inlet connector 15 for water supply to the roller.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figure 3 and Figure 4 As shown, a fluororubber sealing ring 20 is fixedly installed on the left end of the inner cavity of the double-layer guide cover 4. The left side of the fluororubber sealing ring 20 contacts the right side of the fixing sleeve 1. A fluororubber sealing gasket 22 is fixedly installed on the right side of the connecting seat 9. The right side of the fluororubber sealing gasket 22 contacts the lower end of the left side of the sealing plug 8.

[0031] In this technical solution, the fluororubber sealing ring 20 achieves the sealing effect between the fixed sleeve 1 and the double-layer guide cover 4. The fluororubber sealing gasket 22 can effectively seal the connection between the end siphon tube 10 and the docking hole 26. The oil injection nozzle 18 facilitates the oiling and maintenance of the first bearing 17 and the second bearing 19 by personnel during use.
