Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis water purification, in particular to a reverse osmosis membrane component. Background Art

[0002] Reverse osmosis water purification and filtration primarily utilizes the principle of reverse osmosis for water treatment. Reverse osmosis membrane technology applies a certain amount of pressure to water, forcing water molecules and ionic mineral elements to pass through the reverse osmosis membrane. However, most inorganic salts (including heavy metals), organic matter, bacteria, and viruses dissolved in the water cannot pass through the reverse osmosis membrane, thereby strictly separating the purified water that has permeated through it from the concentrated water that has not.

[0003] A search revealed patent publication number CN220745499U, which discloses a "reverse osmosis filter unit" comprising a mounting cover with internal threads threadedly connected to a mounting shell with external threads. A fixing groove is circumferentially disposed above the internal threads along the inner wall of the mounting cover. At least one pair of rotatable fixing blocks is disposed on the side of the mounting shell opposite the mounting cover, adapted to engage within the fixing groove. A rotating rod is fixedly connected to the fixing block on the side opposite the mounting cover. A limiting plate is disposed circumferentially along the mounting shell, forming a receiving cavity between the lower side of the external threads and the outer wall of the mounting shell. A movable block is movably mounted on the outer wall of the limiting plate and is movable up and down along the length of the mounting shell. One end of a transmission rod extends through the receiving cavity and is threadedly connected to the movable block and rotatably connected to the mounting shell. When the movable block is pushed upward, the rotating rod drives the fixed block to rotate out of the fixing groove. This device achieves a reliable and stable connection between the filter unit's internal structures and improves the device's foolproofness.

[0004] In the prior art, the end cap can be engaged with the outer shell and then connected by simply twisting. However, when using the above method, it is difficult to avoid scratching the end cap or misoperation during use, which may cause the end cap to rotate and separate from the outer shell. In addition, the surging water flow during use will cause the device to vibrate, and the continued vibration in subsequent use will cause the end cap to fall off the outer shell, resulting in poor reliability. Summary of the Invention

DETAILED DESCRIPTION

[0023] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0024] Example 1: A reverse osmosis membrane assembly, comprising: a housing 1 having an opening 101 on one side, a central tube 2 coaxially arranged with the housing 1, and an end cap 3 capable of closing the opening 101; a reverse osmosis membrane 7 disposed between the interior of the housing 1 and the central tube 2; the end cap 3 having a plurality of fixing plates 8 having connecting grooves 11 therein spaced circumferentially along the inner wall thereof on one side thereof opposite to the opening 101; a chute 12 disposed along the circumferential outer wall of the opening 101; a stop ring 6 disposed on the side of the chute 12 proximal to the end cap 3; the stop ring 6 having a second through groove 14 disposed therein for the fixing plates 8 to be correspondingly inserted into the chute 12;

[0025] When the reverse osmosis membrane needs to be replaced, the operating panel is pressed to move the guide column installed at the bottom, and the elastic part is deformed. At this time, the guide column drives the inclined block installed at the bottom to slide inside the connecting groove. The inclined surface of the inclined block contacts the inclined surface of the wedge block and can drive the wedge block to move. The wedge block drives the clamping plate installed at the bottom to move in the through groove, so that the clamping plate moves out of the inside of the clamping groove.

[0026] An operating disk 4 is elastically connected to the circumferential outer wall of the end cover 3, one end of a guide column 9 is fixedly connected to the operating disk 4, and the other end can extend into the connecting groove 11 of the fixed plate 8 and is fixedly connected to an inclined block 15. A wedge block 18 that cooperates with the inclined block 15 is slidably installed inside the connecting groove 11, and a through groove 16 that communicates with the connecting groove 11 is provided on the side of the fixed plate 8 opposite to the operating disk 4. A card plate 17 fixedly connected to the wedge block 18 is slidably connected inside the through groove 16. A card slot 13 for the card plate 17 to be embedded in is provided inside the slide groove 12 and along the radial direction of the housing 1;

[0027] Turn the end cover to align the fixed plate inside the end cover with the corresponding second through slot to open it. At this time, pull out the reverse osmosis membrane for replacement, and then put in the new reverse osmosis device and membrane, align the two fixed plates inside the end cover with the second through slot opened on the outer surface of the shell, and rotate along the slide slot. At this time, the card plate enters the corresponding card slot and engages.

[0028] An elastic member 10 is provided between the operating panel 4 and the outer wall of the end cover 3 .

[0029] The elastic member 10 is sleeved on the circumferential outer wall of the guide pillar 9 .

[0030] The above-mentioned latching slot 13 and the second through slot 14 are staggered.

[0031] The fixing plates 8 are distributed at equal intervals.

[0032] The inner wall of the end cover 3 is provided with a sealing gasket 5 that cooperates with the stop ring 6.

[0033] Example 2: A reverse osmosis membrane assembly, comprising: a housing 1 having an opening 101 on one side, a central tube 2 coaxially arranged with the housing 1, and an end cap 3 capable of closing the opening 101; a reverse osmosis membrane 7 disposed between the interior of the housing 1 and the central tube 2; the end cap 3 having a plurality of fixing plates 8 having connecting grooves 11 therein spaced circumferentially along the inner wall thereof on one side thereof opposite to the opening 101; a chute 12 disposed along the circumferential outer wall of the opening 101; a stop ring 6 disposed on the side of the chute 12 proximal to the end cap 3; the stop ring 6 having a second through groove 14 disposed therein for the fixing plates 8 to be correspondingly inserted into the chute 12;

[0034] An operating disk 4 is elastically connected to the circumferential outer wall of the end cover 3, one end of a guide column 9 is fixedly connected to the operating disk 4, and the other end can extend into the connecting groove 11 of the fixed plate 8 and is fixedly connected to an inclined block 15. A wedge block 18 that cooperates with the inclined block 15 is slidably installed inside the connecting groove 11, and a through groove 16 that communicates with the connecting groove 11 is provided on the side of the fixed plate 8 opposite to the operating disk 4. A card plate 17 fixedly connected to the wedge block 18 is slidably connected inside the through groove 16. A card slot 13 for the card plate 17 to be embedded in is provided inside the slide groove 12 and along the radial direction of the housing 1;

[0035] After the fixing plate of the end cover is screwed into the slide groove, the end cover and the shell can be stably connected by the card plate corresponding to the card slot inside the slide groove. The operating panel can also be pressed to move the inclined block downward and push the wedge block upward to disengage the card block from the card slot, thereby improving the stability of the connection between the end cover and the shell, avoiding the situation where the end cover and the shell are separated due to human error, and reducing the situation where the end cover falls off due to vibration during operation, thereby improving the overall reliability.

[0036] An elastic member 10 is provided between the operating panel 4 and the outer wall of the end cover 3 .

[0037] The above-mentioned latching slot 13 and the second through slot 14 are staggered.

[0038] The inner wall of the end cover 3 is provided with a sealing gasket 5 that cooperates with the stop ring 6.

[0039] The above-mentioned slots 13 are distributed at equal intervals.

[0040] The second through groove 14 is a square groove.

[0041] The working principle is:

[0042] During use, when the reverse osmosis membrane needs to be replaced, the operating panel is pressed to drive the guide column installed at the bottom to move, and the elastic member is deformed. At this time, the guide column drives the inclined block installed at the bottom to slide inside the connecting groove. The inclined surface of the inclined block contacts the inclined surface of the wedge block and can drive the wedge block to move. The wedge block drives the clamping plate installed at the bottom to move in the through groove, so that the clamping plate moves out of the inside of the clamping groove.

[0043] Then rotate the end cover to align the fixed plate inside the end cover with the corresponding second through slot to open it. At this time, pull out the reverse osmosis membrane for replacement, and then put in the new reverse osmosis device and membrane, align the two fixed plates inside the end cover with the second through slot opened on the outer surface of the shell, and rotate along the slide groove. At this time, the card plate enters the corresponding card slot and engages.

[0044] By using the above-mentioned reverse osmosis membrane assembly, after the fixing plate of the end cover is screwed into the slide groove, the end cover and the outer shell can be stably connected by the card plate correspondingly embedded in the slot inside the slide groove. The operating panel can also be pressed to move the inclined block downward and push the wedge block upward to disengage the card block from the slot, thereby improving the stability of the connection between the end cover and the outer shell, avoiding the situation where the end cover is separated from the outer shell due to human error, and reducing the situation where the end cover falls off due to vibration during operation, thereby improving the overall reliability.
