Abstract
Description
Technical Field
[0001] The utility model relates to a reverse osmosis membrane component for a water purifier, in particular to a reverse osmosis membrane with a pipeline sterilization function. Background Art
[0002] The reverse osmosis membrane is a commonly used consumable component in a water purifier. When in use, it is installed in a membrane housing and connected to a pipeline for treating raw water by reverse osmosis to produce pure water. After a water purifier using reverse osmosis has been in use for a period of time (such as 1 - 2 years), bacteria will enter the pure water pipeline of the water purifier from the faucet and breed, resulting in an excessive colony count. In addition, when replacing the reverse osmosis membrane in a reverse osmosis water purifier, bacteria will inevitably enter the pure water pipeline and breed, which will also cause an excessive colony count. However, existing water purifiers and reverse osmosis membranes do not have a better way to deal with bacteria in the pure water pipeline.
[0003] In addition, since there are moisture - retaining materials such as glycerol specially set on the surface of the reverse osmosis membrane during the manufacturing process to avoid drying of the membrane material, when replacing the reverse osmosis membrane, existing water purifiers generally need to run the water purifier for 30 - 60 minutes for flushing after replacement and installation. The pure water generated during this process needs to be discharged and cannot be drunk, and it can be safely used only after discharge. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a reverse osmosis membrane with a pipeline sterilization function that can automatically sterilize the pure water pipeline during the flushing time after replacing the reverse osmosis membrane consumable. This reverse osmosis membrane does not need to change the existing manufacturing process and structure, only fills a sterilization module at the end, has low manufacturing and use costs, good sterilization effects, does not require additional flushing time, and has the same replacement and use methods as the existing ones.
[0005] The technical solution adopted by the utility model is as follows: The utility model includes a central tube and a reverse osmosis membrane bag wrapped around the central tube. Source water inlets and pure water outlets are respectively arranged at both ends of the central tube. A sealing ring for isolating the source water side and the wastewater side is sleeved around the periphery of the reverse osmosis membrane bag. The inner cavity of the central tube is divided into two parts, one of which is a pure water cavity. A sterilization module made of a water - soluble sterilization material is preset in the pure water cavity for sterilizing the pure water pipeline after being dissolved during initial flushing.
[0006] The reverse osmosis membrane with a pipeline sterilization function further includes a sterilization module container. The sterilization module is arranged in the sterilization module container, and the sterilization module container is fixedly connected to the pure water outlet at the bottom of the pure water cavity.
[0007] The sterilization module container includes an upper member and a lower member. The top of the upper member is provided with a water inlet, and the bottom of the lower member is provided with a water outlet. After the upper member and the lower member are connected, a cavity for accommodating the sterilization module is formed.
[0008] Hook members are provided on the outer wall of the bottom of the upper member, and openings are provided on the side wall of the lower member. After the bottom of the upper member is inserted into the inner cavity of the lower member, the hook members are snap-connected and fixed to the top wall of the openings.
[0009] Elastic hook members are further provided on the lower member at the openings. After the lower member is inserted into the bottom of the pure water cavity at the pure water outlet, the elastic hook members press against the inner wall of the pure water cavity, so that the sterilization module container is connected and fixed in the pure water cavity.
[0010] The upper member is in the shape of a frustum of a cone with a smaller top and a larger bottom; a positioning boss adapted to the size of the pure water outlet is provided at the bottom of the lower member.
[0011] A connecting ring with one end open is fixedly and sealedly connected outside the reverse osmosis membrane bag, and one end of the sealing ring is inserted into the opening of the connecting ring to achieve connection.
[0012] A sealing ring for sealing connection with the water outlet of the membrane housing assembly is provided around the bottom of the central tube.
[0013] The reverse osmosis membrane bag is a multi-layer membrane bag and is tightly wound around the outside of the central tube.
[0014] The sterilization module is made of a water-soluble disinfectant made of hydrogen peroxide or chlorine dioxide.
[0015] The sterilization module is completely dissolved within 30 minutes after encountering water.
[0016] The beneficial effects of the utility model are as follows: since the utility model includes a central tube and a reverse osmosis membrane bag wrapped around the central tube, a source water inlet and a pure water outlet are respectively arranged at two ends of the central tube, the outer sleeve of the reverse osmosis membrane bag is used to isolate a sealing ring on the source water side and the wastewater side, and the inner cavity of the central tube is divided into two parts, one of which is a pure water cavity, and a sterilization module made of a water-soluble sterilizing material is pre-installed in the pure water cavity, which is used to sterilize the pure water pipeline after being dissolved during the initial flushing; the utility model overcomes the defects and shortcomings of the prior art, and a sterilization module made of a water-soluble sterilizing material is placed in the central tube of the existing reverse osmosis membrane The module can dissolve the bactericidal material to sterilize and disinfect the pure water pipeline by utilizing the existing flushing process when replacing the reverse osmosis membrane, without adding extra flushing time, which not only ensures the safety of use, but also is completely consistent with the existing operation process of replacing the reverse osmosis membrane; therefore, the reverse osmosis membrane with pipeline sterilization effect of the utility model can automatically sterilize the pure water pipeline by utilizing the flushing time after replacing the reverse osmosis membrane consumables.

The outer sleeve of the reverse osmosis membrane bag 2 is used to isolate the sealing ring 3 on the source water side and the wastewater side. The inner cavity of the central tube 1 is divided into two parts, one part of which is a pure water cavity 10. A sterilization module 6 made of water-soluble sterilization material is pre-installed in the pure water cavity 10, which is used to sterilize the pure water pipeline after dissolving during the initial flushing.

[0025] Specifically, the sterilization module container 7 in this embodiment includes an upper member 71 and a lower member 72. The top of the upper member 71 is provided with a water inlet 73, and the bottom of the lower member 72 is provided with a water outlet 74. The upper member 71 and the lower member 72 are connected to form an inner cavity 70 for accommodating the sterilization module 6. A hook 75 is provided on the outer wall of the bottom of the upper member 71, and an opening 76 is provided on the side wall of the lower member 72. After the bottom of the upper member 71 is inserted into the inner cavity 70 of the lower member 72, the hook 75 is connected and fixed with the top wall of the opening 76 by snapping, and the installation is quick and convenient. The lower member 72 is also provided with an elastic hook 78 at the opening 76. After the lower member 72 is inserted into the bottom of the pure water chamber 10 at the pure water outlet 12, the elastic hook 78 presses the inner wall of the pure water chamber 10 to connect and fix the sterilization module container 7 in the pure water chamber 10. The elastic hook 78 increases the adaptability range of the sterilization module container 7. Within the elastic range, it can be applied to the central tube 1 of most existing sizes. The upper member 71 is in the shape of a truncated cone with a small top and a large bottom, which is convenient for the sterilization module container 7 to be inserted into the central tube 1; the bottom of the lower member 72 is provided with a stop boss 77 that is adapted to the size of the pure water outlet 12 to prevent the sterilization module container 7 from being inserted too deep into the central tube 1, ensuring that the sterilization module container 7 is at the pure water outlet 12, so that the amount of flushing pure water flowing through the sterilization module 6 is maximized, which is easy to accelerate dissolution and ensures that there is no residue after the initial flushing.
