The motor 211 in the driving assembly 21 is started. After the motor 211 is powered on, it outputs power to the screw rod 212. The external thread of the screw rod 212 matches the internal thread of the internal threaded tube 213. Under the limiting action of the slide rods 214 on both sides, the internal threaded tube 213 completes the lifting movement, and the replacement of the roll-type reverse osmosis membrane is completed;

[0028] The filter assembly 22 is arranged at the lower part of the internally threaded tube 213, and includes a mounting plate 221 fixedly connected to the lower end of the internally threaded tube 213.
