DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] As Figures 1 to 6As shown, in the prior art, the inventor finds that the prior art has the following problems: One, when the device is cleaning, the water treatment reverse osmosis system cleaning and disinfection is carried out at the same time, and the residual dirt in the second stage will block the first stage reverse osmosis membrane when circulating, resulting in that the cleaning and disinfection effect cannot reach the expected effect; two, using water flow to clean the outer wall of the reverse osmosis system, some stubborn dirt will not be cleaned, resulting in that the cleaning effect is not complete; three, the waste water after cleaning is directly discharged without being treated, resulting in that the available water resources are wasted.

[0027] Therefore, the inventor provides a water treatment reverse osmosis cleaning and disinfection mechanism, which comprises a reverse osmosis device body 1, a cleaning mechanism, a filtered water inlet pipeline 2, and a clean water outlet pipeline 4. The cleaning mechanism is arranged on the right side of the reverse osmosis device body 1. The filtered water inlet pipeline 2 is arranged on the left side of the lower permeation pipe 5 of the reverse osmosis device body 1. The clean water outlet pipeline 4 is arranged on the left side of the reverse osmosis device body 1.

The cleaning water inlet pipeline 7 is arranged on the right side of the reverse osmosis device body 1. The cleaning water outlet pipeline 8 is arranged on the left side of the reverse osmosis device body 1. The cleaning sheet 9 is arranged on the outer side of the inner pipe of the reverse osmosis device body 1.

[0028] By using the above scheme, when the cleaning mechanism is started, the water for cleaning and disinfection enters the pipe of the reverse osmosis device from the cleaning water inlet pipeline 7, is divided by the pressure pump 12 after being pressurized, and enters from the upper end of the outer pipe of the reverse osmosis device, so that the cleaning water surrounds and washes the inner wall and then carries the dirt out of the cleaning water outlet pipeline, preventing the dirt from accumulating and blocking when the two stages are cleaned at the same time, ensuring that the cleaning of the two-stage reverse osmosis device is carried out normally and ensuring the cleaning effect. While the cleaning water is washing, the water flow drives the cleaning sheet 9 to rotate and move forward along the direction of the water flow, so that the dirt that cannot be washed by the cleaning water is cleaned. In this way, the cleaning sheet 9 does not need power and automatically moves and brushes when the cleaning mechanism is started to supply water. After the cleaning is completed, the cleaning sheet is flushed back to the original position, thereby enhancing the cleaning effect and achieving the purpose of energy saving and environmental protection. Finally, the waste water after washing is rotated in the cyclone 16, is filtered after being preliminarily rotated and separated, is deposited, and is further separated into recyclable reclaimed water and dirt, thereby recycling the reclaimed water and saving water resources.

[0034] Wherein, the cleaning and disinfecting water is pressurized by the pressurizing pump 12 and then enters from the water inlet branch pipe 11 from the upper side of the outer pipe of the reverse osmosis device to rotate and flush the pipe wall, achieving the purpose of cleaning.

[0035] Further, the cleaning sheet 9 is further provided with a cleaning brush 13 on the inner and outer sides.

[0036] Wherein, the cleaning brush 13 can flush the pipe wall when the cleaning sheet moves.

[0037] Further, the cleaning sheet 9 is provided with a water permeable hole 14 on the surface, and the water permeable hole 14 is arranged on both sides of the cleaning sheet 9.

[0038] Wherein, the water permeable holes 14 arranged on both sides and in opposite directions, when the cleaning sheet 9 is located at the water inlet branch pipe 11 of the cleaning water inlet pipe 7, it is flushed by the cleaning water and moved to the other side by the water flow, achieving the purpose of cleaning without power; when the cleaning sheet 9 is located at the filter water inlet pipe 2, it is flushed by the water flow in the same way and returns to the water inlet branch pipe 11 of the cleaning water inlet pipe 7.

[0039] Further, the water permeable hole 14 is a tapered through-hole structure.

[0040] Wherein, the tapered through-hole can increase the resistance of the cleaning sheet when the water flow impacts, achieving the effect of flushing the pipe wall.
