Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a press-type reverse osmosis water purification device. Background Technology

[0002] Water purifiers are key devices for purifying water quality. They utilize various filtration technologies, such as activated carbon to adsorb chlorine and organic compounds, ultrafiltration membranes to filter large organic molecules and bacteria, and reverse osmosis membranes to precisely trap dissolved salts, heavy metal ions, and microorganisms under pressure. They remove impurities, pollutants, odors, and harmful substances from the water. Water purifiers come in a variety of types and installation methods, including under-sink and countertop models, and have different filtration levels. They are widely used in homes, businesses, and industries, especially in areas with poor water sources, ensuring healthy drinking water and meeting various high-quality water needs in daily life.

[0003] Early water purifiers were large and space-consuming, often rectangular or cylindrical in shape, with metal or plastic casings. They required demanding operating conditions, needing a relatively flat and load-bearing location for installation. They could only handle common impurities such as sediment, and their effectiveness was poor when dealing with complex water pollution, easily clogging and requiring frequent maintenance. This is where push-button reverse osmosis (RO) water purifiers came in. A piston pressurizes the raw water, causing water molecules to reverse osmosis from the raw water side through the RO membrane to the pure water side. Impurities are trapped, achieving separation of water and solutes. The various filter components are rationally arranged, integrating the booster pump, filter cartridges, etc., into a smaller space. The flow path is optimized to reduce clogging and maintenance frequency. However, during use, manual pressing is still required to squeeze the structure to allow the raw water to pass through the RO membrane for filtration. Prolonged manual pressing is time-consuming, laborious, and inefficient. Utility Model Content

[0015] A junction box is fixedly connected to the right side of the outer wall of the housing, and a spring-loaded charging cable is fixedly connected to the inner wall of the junction box. The spring-loaded charging cable is electrically connected to the DC motor.

[0021] 1. In this utility model, untreated water is introduced into the inlet and flows into the inner wall of the outer shell. The DC motor is started to drive the transmission wheel and the upright rod, which in turn drives the pull rod. The pull rod drives the piston to move up and down. When the piston rises, the water passes through the piston and the one-way ring. When the piston falls, the piston and the one-way ring together press the water into the guide tube and into the perforated ring. Then, through the RO membrane, the clean water enters the water purification pipe and flows out from the inlet. The wastewater flows out from the drain pipe, thus solving the problem of time-consuming and laborious manual pressing.

[0022] 2. In this utility model, the three telescopic shells are tilted outward by rotating the shaft at a certain angle, and the fixed ring restricts the telescopic shell from spreading outward. At this time, the buckle is loosened so that the two limiting blocks can move horizontally outward at the fixed position of the telescopic shell to release the gear. The gear meshes with the telescopic inner rod, which can control the telescopic inner rod to move up and down. When it moves to the overall balance of the casing, the foot nail at the top of the telescopic inner rod is inserted into the ground to fix it. After moving the gear up and down, the buckle is tightened to fix the telescopic inner rod, thereby achieving stable load bearing on the shell. Attached Figure Description

[0032] Reference Figure 1 , Figure 2 and Figure 4The support mechanism 2 includes multiple rotating shafts 208, which serve as connectors. These shafts are rotatably connected to the bottom of the outer wall of the outer casing 1. A telescopic housing 201 is fixedly connected to the outer wall of each shaft 208, enclosing a telescopic inner rod 202. A fixing ring 209 is fixedly connected to the outer wall of the telescopic housing 201, restricting its outward expansion.

The bottom front side of the outer wall of the storage tank 27 has a water outlet 25, and the top of the outer wall of the air bladder 26 has a pressurization port 24.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A power socket 18 is fixedly connected to the top of the outer wall of the outer casing 1. A portable power supply 17 is provided on the top of the power socket 18, and the portable power supply 17 engages with the power socket 18. The portable power supply 17 is electrically connected to the DC motor 4. A junction box 19 is fixedly connected to the right side of the outer wall of the outer casing 1. A spring-loaded charging cable 20 is fixedly connected to the inner wall of the junction box 19 and is electrically connected to the DC motor 4. A fixing block 29 is fixedly connected to the middle of the front side of the outer wall of the outer casing 1. A level 30 is fixedly connected to the inner wall of the fixing block 29.

[0035] Working principle: Before using the device, untreated water flows into the inner wall of the outer casing 1 through the inlet 31. The DC motor 4 is started, which drives the transmission wheel 5. The vertical rod 6 on the transmission wheel 5 drives the pull rod 7, which drives the piston 8 to move up and down. When the piston 8 rises, the telescopic rod 9 extends. The water above the piston 8 separates the piston 8 from the one-way ring 10. The water above the piston 8 passes through the piston 8 and the one-way ring 10. When the piston 8 falls, the water below the piston 8 pushes the one-way ring 10 upward, causing the telescopic rod 9 to retract naturally. The piston 8 and the one-way ring 10 together press the water below into the conduit 11 and into the perforated ring 12. The liquid flowing out of the perforated ring 12 is separated through the RO membrane 13. The clean water enters the clean water pipe 14 and flows out through the inlet 15. The wastewater flows out through the drain pipe 16, thus solving the problem of time-consuming and laborious manual pressing.

[0036] Furthermore, through the support mechanism 2, during assembly, the three telescopic shells 201 are tilted outward at a certain angle by the rotating shaft 208, and the telescopic shells 201 are restricted from spreading outward by the fixing ring 209. At this time, the buckle 207 is loosened so that the two limiting blocks 203 can move horizontally outward at the fixed position of the telescopic shell to release the gear 205. The gear 205 meshes with the telescopic inner rod 202, which can control the telescopic inner rod 202 to move up and down. When the telescopic inner rod 202 is moved until the overall casing 1 is roughly balanced, the foot nail 207 at the top of the telescopic inner rod is inserted into the ground to fix it. Then, the gear 205 is finely adjusted to make the casing 1 more balanced. After moving the gear 205 up and down, the buckle 206 is tightened to fix the telescopic inner rod 202, thereby achieving stable load bearing on the casing 1.
