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

[0002] Reverse osmosis filter cartridges are one of the core components of reverse osmosis water purifiers. They are filter materials that use high pressure to force tap water to pass through a reverse osmosis membrane in the opposite direction, filtering out impurities, bacteria, viruses, heavy metals and other harmful substances in the water.

[0003] After prolonged use, reverse osmosis filter cartridges need to be removed from their housings for cleaning or replacement. However, the current reverse osmosis filter cartridge housings are inconvenient to disassemble, resulting in low operational efficiency during actual disassembly and installation. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a reverse osmosis membrane filter element to solve the problem mentioned in the background art that the current reverse osmosis filter element is not easy to remove from the filter element housing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reverse osmosis membrane filter element, comprising a reverse osmosis membrane filter element body, an outer shell component provided on the outside of the reverse osmosis membrane filter element body, the outer shell component comprising a shell cylinder component, a cylinder head provided at one end of the shell cylinder component, a side wing block provided on the side of the shell cylinder component, a pull ring component provided on the outside of the shell cylinder component, a vertical rod component, a spring component, a locking block component and an insert rod component provided inside the side wing block, and a sealing ring component provided inside the shell cylinder component.

[0006] Preferably, the surface of the pull ring is provided with anti-slip texture, and there are two sets of vertical rods, springs, locking blocks, insert rods and side wing blocks, which are symmetrically distributed on both sides of the shell cylinder. The reverse osmosis membrane filter element body is installed inside the shell cylinder.

[0007] Preferably, the side wing block is connected to the shell cylinder, one end of the vertical rod is connected to the pull ring, the other end of the vertical rod is connected to the locking block, and the locking block contacts the insert rod through a locking groove.

[0008] Preferably, the locking block is in sliding contact with the side wing block via a groove, and the vertical rod is in sliding contact with the side wing block via a through hole.

[0011] Preferably, the sealing ring is connected to the housing cylinder via a groove, and the sealing ring contacts the cylinder head via the groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This reverse osmosis membrane filter element is equipped with an outer shell. After prolonged use, the reverse osmosis filter element needs to be removed from the filter element shell for cleaning or replacement. However, current reverse osmosis filter element shells are inconvenient to disassemble, resulting in low operational efficiency during actual disassembly and installation. The corresponding outer shell design addresses this by first pulling the pull ring away from the side wing blocks when removing the reverse osmosis membrane filter element from the shell. Pulling the pull ring will move the vertical rod and locking block, causing the spring to retract and the locking block to disengage from the slot of the insertion rod. This allows the shell and head to separate, enabling the removal of the reverse osmosis membrane filter element from the shell. When installing the shell and head, simply... Next, insert the insert rod into the slot of the side wing block. During the insertion and removal process, the insert rod will push open the locking block, allowing the locking block to retract into the sliding groove of the side wing block. The spring will store and retract its force. When the insert rod is fully inserted into the slot of the side wing block, the spring will release its stored force, and the locking block will be pushed out to contact the locking groove of the insert rod. At this time, the insert rod will be locked in the side wing block. This completes the connection between the shell cylinder and the cylinder head. In this overall design, the components can automatically cooperate to lock during the insertion process, without the need for complicated alignment, screwing and other tedious steps. The overall installation process is simple and quick. When disassembling, you only need to pull the pull ring to unlock it. Then the cylinder head and the shell cylinder will separate. The overall design reduces the time and effort spent on installation and disassembly.

[0014] 2. This reverse osmosis membrane filter element is equipped with an outer shell. The sealing ring in the outer shell is designed to be squeezed inside the shell and the head after the shell and head are installed. The sealing ring can ensure the sealing of the connection between the shell and the head and prevent water leakage during actual use. Attached Figure Description

[0023] The surface of the pull ring 23 is provided with anti-slip texture. There are two sets of vertical rods 24, springs 25, locking blocks 26, insertion rods 27 and side wing blocks 28. The two sets of vertical rods 24, springs 25, locking blocks 26, insertion rods 27 and side wing blocks 28 are symmetrically distributed on both sides of the shell cylinder 21. The reverse osmosis membrane filter element body 01 is installed inside the shell cylinder 21.

[0024] The side wing block 28 is connected to the shell cylinder 21, one end of the vertical rod 24 is connected to the pull ring 23, and the other end of the vertical rod 24 is connected to the locking block 26. The locking block 26 contacts the insertion rod 27 through the locking groove.

[0025] The locking block 26 slides in contact with the side wing block 28 through the groove, and the vertical rod 24 slides in contact with the side wing block 28 through the through hole.

[0026] One end of the spring member 25 is connected to the side wing block 28, and the other end of the spring member 25 is connected to the locking block member 26.

[0027] The insert rod 27 is connected to the cylinder head 22, and the insert rod 27 contacts the side wing block 28 through the slot.

[0028] The sealing ring 29 is connected to the shell cylinder 21 through a groove, and the sealing ring 29 contacts the cylinder head 22 through the groove.

[0029] Working Principle: After prolonged use, reverse osmosis filter cartridges need to be removed from the cartridge housing for cleaning or replacement. However, current reverse osmosis filter cartridge housings are inconvenient to disassemble, resulting in low operational efficiency during actual disassembly and installation. In the corresponding outer housing component 02, when the reverse osmosis membrane filter cartridge body 01 needs to be removed from the housing cylinder 21, first pull the pull ring 23 to move it away from the side wing block 28. Pulling the pull ring 23 will move the vertical rod 24 and the locking block 26, causing the spring 25 to retract and the locking block 26 to disengage from the slot of the insertion rod 27. Then, the housing cylinder 21 and the cylinder head 22 can be separated, allowing the reverse osmosis membrane filter cartridge body 01 to be removed from the housing cylinder 21. When installing the housing cylinder 21 and the cylinder head 22, simply insert the insertion rod 27. When inserted into the slot of the side wing block 28, the insertion rod 27 pushes open the locking block 26 during insertion and removal, causing the locking block 26 to retract into the groove of the side wing block 28. The spring 25 stores and retracts. When the insertion rod 27 is fully inserted into the slot of the side wing block 28, the spring 25 releases its stored force, and the locking block 26 is pushed out and contacts the slot of the insertion rod 27. At this time, the insertion rod 27 is locked in the side wing block 28, thus completing the connection between the shell cylinder 21 and the cylinder head 22. This overall design allows each component to automatically cooperate and lock during insertion, eliminating the need for complicated alignment, twisting, and other tedious steps. The overall installation process is simple and quick. Disassembly only requires pulling the pull ring 23 to unlock, after which the cylinder head 22 and the shell cylinder 21 separate. The overall design reduces the time and effort spent on installation and disassembly. After the outer shell component 02 is installed, the sealing ring component 29 in the outer shell component 21 and the cylindrical head 22 will be squeezed inside the outer shell component 21 and the cylindrical head 22. The sealing ring component 29 can ensure the sealing of the connection between the outer shell component 21 and the cylindrical head 22 and prevent water leakage during actual use.
