[0040] Among them Figure 6 and Figure 7 As shown, the driving assembly includes a gear groove 407 arranged inside the slider 405, and a first gear 408 is rotatably arranged inside the gear groove 407. The gear shaft of the first gear 408 is fixedly connected to the rotating shaft of the brush 406, and a second gear 409 is meshingly arranged on one side of the first gear 408. One end of the gear shaft of the second gear 409 extends to the inside of the slider 405 and is fixedly connected to the output end of the third motor 410. Starting the third motor 410 drives the second gear 409 to rotate, and then drives the first gear 408 and the brush 406 to rotate, so as to start the cleaning operation. The third motor 410 is a waterproof motor to prevent liquid from affecting the internal structure of the third motor 410.

[0041] Among them Figure 2-Figure 4 As shown, the suction assembly includes a suction pump 411 fixedly mounted on one side of the housing 101. The suction pump 411 is a common suction pump structure in the field to prevent damage to the internal structure of the suction pump 411 due to the entry of liquid and impurities. The input end of the suction pump 411 is fixedly connected to an input pipe 412, and the other end of the input pipe 412 passes through the slider 405 and is fixedly connected to a plurality of absorption covers 413. The absorption covers 413 are symmetrically and obliquely arranged on both sides of the slider 405 to facilitate the absorption of impurities into the absorption covers 413.

[0045] During use, the staff injects concentrated water into the concentrated water chamber 102 through the liquid inlet 107, and the first motor 202 drives the stirring roller 201 and the stirring rod 203 to rotate, so as to prevent the precipitation of impurities in the concentrated water. The buffer water content in the buffer chamber 105 is known according to the liquid level meter. When a large amount of buffer water is not needed, the concentrated water is injected into the reverse osmosis chamber 104 through the pump 305 and the second infusion tube 302. The reverse osmosis membrane 106 performs reverse osmosis on the concentrated water on the concentrated water side through its own reverse osmosis effect. The reverse osmosis efficiency is relatively low, so as to avoid the buffer chamber 105 being unable to meet the buffering effect due to the production of more pure water, reduce the start and stop times of the booster pump 304, extend its service life, and prevent the device from losing The reverse osmosis effect leads to idleness. When a large amount of buffer water is needed, the concentrated water is injected into the reverse osmosis chamber 104 through the booster pump 304 and the first infusion pipe 301, increasing the pressure on the concentrated water side, thereby increasing the reverse osmosis effect of the reverse osmosis membrane 106, and the reverse osmosis efficiency is relatively large, thereby meeting the user's use needs. When the surface cleaning operation of the reverse osmosis membrane 106 is required, the staff stops injecting concentrated water into the concentrated water chamber 102, closes the first one-way valve 303 and the second one-way valve 306, and starts the second motor 403 and the third motor 410. With the cooperation of the brush 406, the suction pump 411 can absorb impurities and dirt into the collection box 414, thereby extending the service life of the reverse osmosis membrane 106.

[0046] Among them Figure 8 As shown, a treatment process of a reverse osmosis membrane concentrated water recycling device, the specific process is as follows:

[0047] S1, the concentrated water enters the concentrated water chamber 102 through the liquid inlet 107, and the concentrated water is stirred to prevent sedimentation;

[0048] S2. When the buffering water in the buffer chamber 105 is large, the pump 305 is started to make the concentrated water in the concentrated water chamber 102 enter the reverse osmosis chamber 104 to start the reverse osmosis operation. When the buffering water in the buffer chamber 105 is small, the booster pump 304 is started to make the concentrated water in the concentrated water chamber 102 enter the reverse osmosis chamber 104 to start the reverse osmosis operation.

[0049] S3, concentrated water enters the reverse osmosis chamber 104, and water molecules in the concentrated water side enter the water production side through the reverse osmosis membrane 106 to produce pure water. When it is observed through the observation window 109 that there are many impurities on the surface of the reverse osmosis membrane 106, the first one-way valve 303 is closed, and the suction pump 411 and the third motor 410 are started to perform a cleaning operation;

[0050] S4. Purified water enters the buffer chamber 105 through the delivery pipe 110 . When the domestic water end uses water, the purified water is discharged through the drain port 108 .

[0051] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
