Description

Technical Field

[0001] This utility model relates to the field of purification device technology, and in particular to an RO membrane purification device. Background Technology

[0002] RO membrane purification technology, also known as reverse osmosis membrane technology, is a membrane separation technology that relies on pressure difference to apply pressure to the side with a high concentration solution, causing it to flow to the side with a low concentration solution, thus separating the solution and solute. RO membrane purification devices, also known as water purifiers, can effectively remove harmful substances such as bacteria, viruses, heavy metals, and pesticide residues from water, providing pure water suitable for direct drinking.

[0003] For ease of use, RO membrane purification devices are mostly installed inside kitchen cabinets. However, current technology makes it inconvenient to install and secure RO membrane purification devices. Therefore, they are simply placed inside the cabinet without proper support, resulting in instability. Furthermore, the operation of the RO membrane purification device generates vibrations, and the pressure pump, housing, and the housing collide with the cabinet, producing noise. This leads to a poor user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing RO membrane purification device is inconvenient to install and fix, so it is placed directly inside the cabinet. It lacks fixation, is unstable, and the RO membrane purification device will vibrate when it is running. The pressure pump and the housing, as well as the housing and the cabinet, will collide and generate noise, resulting in a poor user experience.

One end of the first water pipe extends through into the interior of the second housing and is fixedly connected to the inlet of the pressure pump. A second water pipe is fixedly connected to the outlet of the pressure pump. One end of the second water pipe extends through into the top of the partition and is fixedly installed on one side of the surface of the RO membrane purification cartridge. A pure water pipe is fixedly connected to the other side of the surface of the RO membrane purification cartridge. One end of the pure water pipe extends through into the outer side wall of the second housing and is fixedly connected to a pure water outlet.

[0007] Preferably, the telescopic fixing assembly includes a third housing, which is fixedly connected to the top of the second housing. Two placement holes are opened on both sides of the top of the second housing. Two lead screws are movably connected inside the two placement holes. Two limiting posts are fixedly connected to the bottom of the two placement holes. Two limiting holes are opened at the bottom of the two lead screws. The two limiting posts are slidably installed into the two limiting holes to prevent the lead screws from rotating with the worm gear, ensuring that the lead screws can rise and fall with the rotation of the worm gear. A top plate is fixedly connected to the top of each of the two lead screws extending through the top of the third housing. Worm gears are threaded onto the outside of each of the two lead screws. The two worm gears are located inside the third housing, and the bottom of each worm gear is rotatably connected to the top of the second housing.

[0008] Preferably, a shaft is rotatably connected between the two sides of the inner surface of the third housing, and two worms are fixedly connected to the shaft near the outside of the two worm wheels. The two worms are respectively meshed with the two worm wheels, and the two worms can drive the two worm wheels to rotate.

[0009] Preferably, one end of the shaft extends through the outside of the third housing and is fixedly connected to a handwheel to facilitate the rotation of the shaft.

[0010] Preferably, the shock absorption assembly includes multiple telescopic rods, all of which are fixedly installed at the inner bottom of the second housing.

[0013] Preferably, the two top plates and multiple legs are made of rubber, which provides better shock absorption and noise reduction.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up components such as a worm gear, worm wheel, top plate, and support feet, uses a shaft to drive the worm gear to rotate and mesh with the worm wheel for transmission. The lead screw, along with the rotation of the worm wheel, drives the top plate to move up and down, placing the RO membrane purification device inside the cabinet. The lead screw rises, causing the top plate to press against the top of the cabinet, thus fixing the RO membrane purification device and making the installation more stable. At the same time, the rubber support feet can reduce the noise generated by vibration and collision with the cabinet during operation. Compared with the existing technology, it is quieter to use and provides a better user experience.

[0016] 2. This utility model, by setting sound insulation cotton and shock absorption components, utilizes the springs and damping on the shock absorption components to reduce the vibration of the pressure pump fixedly mounted on the mounting plate, thus avoiding large vibrations during the operation of the pressure pump. At the same time, sound insulation cotton is set on the inner side wall of the second housing and the inner surface of the switch door to further reduce noise. Attached Figure Description

One end of the pure water pipe 9 extends through into the outer side wall of the second housing 2 and is fixedly connected to a pure water outlet 10.

[0027] like Figures 1 to 6As shown, the two top plates 13 and multiple support legs 3 are made of rubber, providing better shock absorption and noise reduction. The telescopic fixing assembly includes a third housing 11, which is fixedly connected to the top of the second housing 2. Two placement holes 201 are opened on both sides of the top of the second housing 2. Two lead screws 12 are movably connected inside the two placement holes 201. Two limiting posts 202 are fixedly connected to the bottom of the two placement holes 201. Two limiting holes are opened at the bottom of the two lead screws 12. The two limiting posts 202 are slidably installed into the two limiting holes respectively. Inside, the screw 12 is prevented from rotating with the worm gear 14, ensuring that the screw 12 can rise and fall with the rotation of the worm gear 14. The top ends of both screws 12 extend through to the top of the third housing 11 and are fixedly connected to a top plate 13. The outside of both screws 12 is threadedly connected to worm gears 14. The two worm gears 14 are located inside the third housing 11, and the bottom of both worm gears 14 are rotatably connected to the top of the second housing 2. A shaft 15 is rotatably connected between the two sides of the inner surface of the third housing 11. The shaft 15 is sleeved near the outside of the two worm gears 14. Two worm gears 16 are fixedly connected, and each worm gear 16 is meshed with a worm wheel 14. The two worm gears 16 can drive the two worm wheels 14 to rotate. One end of the shaft 15 extends through to the outside of the third housing 11 and is fixedly connected to a handwheel 17 to facilitate the rotation of the shaft 15. The shock absorption assembly includes multiple telescopic rods 18, which are all fixedly installed at the bottom of the second housing 2. The output ends of the multiple telescopic rods 18 are fixedly connected to a mounting plate 19. The pressure pump 4 is fixedly installed on the top of the mounting plate 19. The outside of the multiple telescopic rods 18... Each part is fitted with a spring 20.

A damper 21 is fixedly installed on the bottom inner side of the second housing 2. The output end of the damper 21 is fixedly installed on the bottom of the mounting plate 19. The damper 21 can work with the springs 20 to achieve better vibration reduction. An inspection port is opened on the outer side wall of the second housing 2. A switch door 22 is installed at the bottom of the inspection port through a hinge. Sound insulation cotton 23 is fixedly connected to the inner wall of the second housing 2 and the inner surface of the switch door 22 on one side, which provides better sound insulation.

[0028] In use, the RO membrane purification device is placed inside a cabinet. Rotating the handwheel 17 rotates the shaft 15, which in turn rotates the worm gear 16. The worm gear 16 meshes with the worm wheel 14, causing the worm wheel 14 to rotate. As the worm wheel 14 rotates, the lead screw 12 moves upwards, causing the top plate 13 at its tip to abut against the top of the cabinet. This secures the RO membrane purification device. The rubber feet 3 at the bottom of the first housing 1 reduce noise generated by vibration and contact with the cabinet during operation. Water enters through the inlet pipe 104 and passes through various channels. After initial purification by the granular activated carbon filter cartridge 101, the granular activated carbon filter cartridge 102, and the compressed activated carbon filter cartridge 103, the water is pressurized by the pressurizing pump 4 and flows into the RO membrane purification cartridge 6. After being purified by the RO membrane purification cartridge 6, the water is discharged from the pure water outlet 10. The spring 20 and the damper 21 can dampen the vibration generated by the pressurizing pump 4 during operation, thereby reducing the noise generated by the pressurizing pump 4. The sound insulation cotton 23 fixedly connected to the inner wall of the second housing 2 and the inner surface of the switch door 22 can further reduce the noise. Compared with the existing technology, the RO membrane purification device is quieter during operation, with very little noise, and provides a better user experience.
