Detailed ways

The utility model is a water purifier 100, which can be placed on the countertops of kitchens, living rooms, rooms, offices and other places. The water purifier 100 occupies a small space and is easy to install and use.

Referring to Figures 1 to 6, the water purifier 100 of the present invention includes: a casing 1, a water storage tank 2 installed in the casing 1, several filter elements 3 for purifying raw water, and a A clean water tank 4 for clean water after the filter element 3 has purified it.

The water storage tank 2 includes a raw water tank 21 for containing raw water and a concentrated water tank 22 for containing concentrated water.

The raw water tank 21 and the concentrated water tank 22 are installed in the casing 1 and can be disassembled from the casing 1, the clean water tank 4 is fixed in the casing 1, and the raw water tank 21 is connected to In the filter core 3, the raw water is collected in the clean water tank 4 after passing through the filter core 4. The raw water tank 21, the clean water tank 4 and the concentrated water tank 22 are all made of food-grade PP material. The clean water Tank 4 can store up to 5 liters of clean water.

The filter core 3 includes an RO reverse osmosis filter core 31, the RO reverse osmosis filter core 31 is provided with an RO reverse osmosis filter membrane 310 capable of filtering almost all impurities except water molecules, and the RO reverse osmosis filter core includes Water inlet 311, purified water outlet 312 and concentrated water outlet 313, water enters through water inlet 311 and passes through the RO reverse osmosis filter membrane 310 under pressurized, the water passing through the RO reverse osmosis filter membrane 310 is passed through the purified water The outlet 312 flows out, and the concentrated water outlet 313 is connected with a flush valve (not shown), and the impurities filtered by the RO reverse osmosis filter membrane 310 will remain on the outside of the RO reverse osmosis membrane 310, and long-term accumulation will lead to RO The reverse osmosis membrane 310 is blocked, and the flushing valve is closed to maintain the water pressure in the RO reverse osmosis filter core 31 in the case of general filtered water. When the impurities in the RO reverse osmosis filter core 31 accumulate too much , the flush valve is opened, at this time, water enters the RO reverse osmosis filter element 31 and flushes the outer surface of the RO reverse osmosis membrane 310, and the impurities on the outer surface of the RO reverse osmosis membrane 310 flow out of the RO reverse osmosis membrane 310 through the flush valve. The RO reverse osmosis filter core 31 is used to clean the RO reverse osmosis membrane 310 to prolong the life of the RO reverse osmosis filter core 31 .
