Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane filter technology, specifically a high-flow reverse osmosis membrane filter. Background Technology

[0002] Reverse osmosis water purifier filter cartridges are a type of filtration equipment used in water purifiers, and they are crucial for the production of pure water.

[0003] Existing patent CN220834956U discloses a reverse osmosis membrane filter element, including a cylindrical body and a reverse osmosis membrane filter element. The cylindrical body is provided with a disassembly and assembly mechanism, which includes an arc-shaped groove. The arc-shaped groove is opened at the bottom of the cylindrical body, and a hinge is fixedly connected to the right side of the cylindrical body.

[0004] The aforementioned patents or existing reverse osmosis membrane filter cartridges have the following problems:

[0005] Existing high-flow reverse osmosis membrane filter cartridges have a large water volume, so impurities are filtered out and remain on the filter membrane. Therefore, the filter membrane needs to be cleaned regularly. However, the current cleaning of the filter membrane is inconvenient, resulting in a slow cleaning speed. Utility Model Content

[0006] The purpose of this invention is to provide a high-flow reverse osmosis membrane filter element to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-flow reverse osmosis membrane filter element, including a mounting base, a filter membrane frame provided on the surface of the mounting base, a filter membrane mounted on the filter membrane frame, a cleaning structure provided on the filter membrane frame, the cleaning structure including a pull column, a pull column provided in the filter membrane frame, a connecting frame provided on the surface of the pull column, a pressure ring fixed on the surface of the connecting frame, a connecting plate provided on the surface of the pressure ring, a fixing ring provided at the end of the connecting plate, and a brush provided on the surface of the fixing ring.

[0008] Preferably, the mounting base surface is provided with a spiral column, and the pull column is sleeved on the surface of the spiral column.

[0009] Preferably, the pull column is provided with a rotating ring, the rotating ring is connected to the spiral column, and the connecting frame is fixed on the surface of the rotating ring.

[0010] Preferably, the end of the pull column is provided with a sealing ring, and the sealing ring is elastic.

[0011] Preferably, when the pressure ring is compressed, the sealing ring is pressed tightly against the surface of the mounting base.

[0012] Preferably, the connecting plate is provided with a brush plate, and there are two brush plates arranged in a cross pattern.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the mounting bracket is installed inside the water purifier, the cleaning structure will not affect the normal use of the filter membrane;

[0015] Remove the device from the water purifier, then place the device in the water. Hold and repeatedly push and pull the pull column to allow the brush to clean the filter membrane, causing impurities to detach from the filter membrane. This achieves the beneficial effect of conveniently cleaning the filter membrane and improves the cleaning speed.

[0016] When the pull column is pulled, the rotating ring is spirally connected to the spiral column, which drives the connecting plate. This causes the brush to rotate as it cleans the filter membrane surface, thus improving the cleaning ability. Attached Figure Description

Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0023] Please see Figure 1 and Figure 2 This utility model provides a high flow reverse osmosis membrane filter element, including a mounting base 1, a filter membrane frame 2 integrally formed on the mounting base 1, a filter membrane 3 installed on the filter membrane frame 2, the filter membrane 3 being a reverse osmosis filter membrane, and a cleaning structure 4 provided on the filter membrane frame 2;

[0024] Install the mounting base 1 inside the water purifier, and the water will be filtered through the filter membrane 3.

[0025] Please see Figure 2 , Figure 3 and Figure 4This utility model provides a high flow reverse osmosis membrane filter element. The cleaning structure 4 includes a pull column 41. The pull column 41 is provided inside the filter membrane frame 2. A connecting frame 42 is provided on the surface of the pull column 41. A pressure ring 43 is integrally formed on the surface of the connecting frame 42. A connecting plate 44 is provided on the surface of the pressure ring 43. A fixing ring 45 is provided at the end of the connecting plate 44. A brush 46 is provided on the surface of the fixing ring 45. The brush 46 is in close contact with the surface of the filter membrane 3.

[0026] When the mounting base 1 is installed inside the water purifier, the pressure ring 43 is pushed and pressed while the device is fixed, so that the cleaning structure 4 is fixed on the device. This ensures that when the filter element is fixed inside the water purifier, the cleaning structure 4 will not affect the normal use of the filter membrane 3.

[0027] When cleaning is required, remove the device from the water purifier, place the device in the water, and then hold and repeatedly push and pull the pull column 41. This will drive the connecting frame 42, causing the connecting plate 44 to drive the fixing ring 45, moving repeatedly. This allows the brush 46 to clean the filter membrane 3, causing impurities to detach from the filter membrane 3, thus achieving the beneficial effect of convenient cleaning of the filter membrane 3 and improving the cleaning speed.

[0028] A spiral column 47 is fixed on the surface of the mounting base 1. A pull column 41 is sleeved on the surface of the spiral column 47. The pull column 41 slides along the surface of the spiral column 47. The spiral column 47 will not tilt when the pull column 41 is pulled repeatedly. A sealing ring 49 is provided at the end of the pull column 41. The sealing ring 49 is elastic. When the pressure ring 43 is pressed, the sealing ring 49 is pressed tightly against the surface of the mounting base 1, effectively preventing water from entering the interior of the spiral column 47.

[0029] A rotating ring 48 is rotatably connected to the pull column 41. The rotating ring 48 is spirally connected to the spiral column 47. The connecting frame 42 is fixed to the surface of the rotating ring 48.

[0030] When the pull column 41 is pulled, since the rotating ring 48 is spirally connected to the spiral column 47, when the pull column 41 slides along the surface of the spiral column 47, the rotating ring 48 will move along the spiral column 47 and rotate at the same time, thereby driving the connecting frame 42 to rotate, and causing the connecting plate 44 to drive the fixed ring 45 to rotate, so that the brush 46 will rotate together when cleaning the surface of the filter membrane 3, thus improving the cleaning ability.

[0031] The connecting plate 44 is provided with a brush plate 410. There are two brush plates 410, which are arranged in a cross shape to improve cleaning ability and effectively reduce cleaning time.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
