Description

Technical Field

[0001] This utility model relates to the field of water purifier filtration technology, and in particular to a reverse osmosis filter element for a water purifier. Background Technology

[0002] A reverse osmosis filter cartridge for water purifiers is an artificial semi-permeable membrane with certain characteristics, made by simulating a biological semi-permeable membrane. It mainly utilizes the principle of reverse osmosis, which forces water through the semi-permeable membrane under pressure, thereby trapping impurities in the water. It effectively removes bacteria, heavy metals, and organic pollutants from the water, and can deeply purify the water, providing users with safe and pure drinking water.

[0003] As people's living standards and health awareness improve, more and more people are paying great attention to drinking water issues. As a result, the demand for water purifiers has increased significantly. As a key filtration component in water purifiers, the reverse osmosis filter plays a very important role and determines the water purification effect of the water purifier.

[0004] In existing reverse osmosis filter cartridges, raw water is directly filtered through the reverse osmosis membrane on its outer wall during use. However, the membrane is constantly clogged by impurities in the water, resulting in a relatively short lifespan. Replacing the reverse osmosis filter cartridge is also complex and relatively expensive, and frequent replacements increase the user's operating costs. Furthermore, the reverse osmosis filtration process requires applying pressure to force the water through the membrane, which generates a large amount of wastewater, causing serious water waste. This problem is particularly prominent in water-scarce areas. Therefore, a reverse osmosis filter cartridge for water purifiers is proposed to solve the above problems. Utility Model Content

Spring buckles 9 are fixedly connected to the outer wall of the filter plates 7 on the left and right sides. The spring buckles 9 are fastened in the slots 6. A handle 10 is fixedly connected to the top of the filter plates 7. When the raw water enters from the water inlet 11, it first passes through the filter plates 7 in the filter cylinder 5 to filter out larger impurities, and then enters the filter element below the filter cylinder 5 for secondary filtration to prevent larger particulate impurities from clogging the filter element and reducing the service life of the filter element. When there are too many impurities on the filter plates 7, multiple filter plates 7 can be removed and replaced at will.

[0036] Furthermore, the filter element and the protective cylinder 2 are fixedly connected below the protective cylinder 2 by a connecting ring 23. A fixing ring 14 is fixedly connected to the bottom of the filter element. The inner wall of the fixing ring 14 has a fixing block 15, which connects the recycling mechanism 13 to the bottom of the filter element. A water pipe interface 16 is opened at the bottom of the fixing ring 14, which connects to the wastewater inlet pipe 1302. An inlet valve 1304 is connected to the outer wall of the inlet pipe 1302. The other end of the inlet pipe 1302 is connected to the wastewater tank 1301. The wastewater filtered by the filter element enters the wastewater tank 1301 through the inlet pipe 1302. A water immersion sensor 1309 is connected to the bottom of the lid 1307 on the top of the wastewater tank 1301. When the wastewater in the wastewater tank 1301 comes into contact with the water immersion sensor 1309, the water immersion sensor 1309 emits an alarm sound. At this time, the outlet valve 1306 on the right side of the outer wall of the wastewater tank 1301 can be opened, and the wastewater can be discharged through the outlet pipe 1305.
