[0030] A shrink guide ring 8 is installed inside one end of the housing 1 close to the water inlet cap 2, and the shrink guide ring 8 is used to guide the water entering from the water inlet cap 2 to the inside of the reverse osmosis membrane roll 7;

[0031] A limiting ring 9 is installed inside one end of the housing 1 close to the sealing cover 3, a positioning sleeve 10 is slidably connected inside the limiting ring 9, a plurality of springs 11 are distributed on the inner circumference of the limiting ring 9, two ends of the spring 11 are respectively fixedly connected to the limiting ring 9 and the positioning sleeve 10, and a plurality of sieve holes 12 penetrating the positioning sleeve 10 are opened inside the positioning sleeve 10;

[0032] A sealing rubber 13 is fixedly connected to the inner side of the water inlet sealing cap 2 which contacts the shrink guide ring 8;

[0035] In this embodiment, when the device is in use, after the water flows into the housing 1 through the one-way water inlet membrane of the water inlet sealing cap 2, the water flow is blocked by the shrink guide ring 8, so that the water flows into the reverse osmosis membrane roll 7, and the water flow generates pressure between the reverse osmosis membrane roll 7 and the housing 1, so that the pure water enters the middle water collecting pipe 5 through the water collecting hole 6, while the waste water cannot pass through the reverse osmosis membrane roll 7, so that the waste water is discharged from the sewage outlet 4 through the sieve hole 12 in the positioning sleeve 10, and the sealing rubber 13 seals the connection between the water inlet sealing cap 2 and the shrink guide ring 8;

[0037] After wrapping the new reverse osmosis membrane roll 7 on the outer wall of the middle water collecting pipe 5, one end of the reverse osmosis membrane roll 7 is inserted into the limiting ring 9, so that the reverse osmosis membrane roll 7 squeezes the positioning sleeve 10, so that the spring 11 stretches, and the reverse osmosis membrane roll 7 is placed in the housing 1, and the reverse osmosis membrane roll 7 passes through the shrink guide ring 8, so that the reverse osmosis membrane roll 7 is fixed, and then the water inlet sealing cap 2 and the sealing cover 3 are rotated to squeeze and fix the shrink guide ring 8 and the limiting ring 9 respectively, and the spring 11 will push the reverse osmosis membrane roll 7 (it should be noted that: the elastic force of the spring 11 is greater than the friction between the reverse osmosis membrane roll 7 and the limiting ring 9), so that one end of the reverse osmosis membrane roll 7 contacts the water inlet sealing cap 2;

[0042] In this embodiment, this structure can prevent water from flowing through the gap when the device is in use, thereby affecting the water purification effect.

[0043] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a notch having a diameter equal to that of the reverse osmosis membrane roll 7 is formed inside the positioning sleeve 10 .

[0044] In this embodiment, when the reverse osmosis membrane roll 7 is installed, this structure enables the positioning sleeve 10 to be sleeved on one end of the reverse osmosis membrane roll 7, so that the spring 11 can drive the reverse osmosis membrane roll 7 to move.

[0045] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the material of the limiting ring 9 is hard rubber.
