The reverse osmosis water purifier provided by the present invention is described in more detail with reference to the accompanying drawings and the specific embodiments.

Referring to fig. 1 and 2, in an embodiment of the present invention, a purified water tank 5 of a reverse osmosis water purifier is disposed at a top end of a main housing 1, a space for accommodating the purified water tank 5 is opened at the top end of the main housing 1, and the purified water tank 5 is sealed in the main housing 1 by turning an opened flip cover; the bottom of main casing body 1 is equipped with the list and opens the door, and the inside space that holds storage water tank 4 that forms of singly opening the door, the filter equipment that draws water connects storage water tank 4 and water purification case 5, and the raw water in the extraction storage water tank 4 filters, carries clean water to water purification case 5 after filtering and stores reserve, drains waste water back to storage water tank 4 and stores to in the filtration of next time, improved the circulation number of times of raw water, using water wisely that can the certain degree. When the liquid level of the raw water in the water storage tank 4 is lower than a certain degree, the single-door is opened, the water storage tank 4 is taken out, the waste water is poured out, and the water storage tank 4 is placed in place after the raw water is supplemented.

Certainly, storage water tank 4 and water purification case 5 not only can take the mode as shown in fig. 1 to set up, can also set up according to actual need is nimble, and the mouth of drawing water through the filter equipment that draws water and the waste water discharging mouth are connected simultaneously in storage water tank 4, have reduced the setting of waste water case, and under the condition of storage water tank 4 and water purification case 5 of the same volume, the volume of purifier can accomplish littleer, and under the prerequisite of the purifier of the same volume, the capacity that storage water tank 4 and water purification case 5 can be done is bigger.

In the above embodiment, the water pumping filter device includes the water pumping connection pipe 6, two ends of the water pumping connection pipe 6 are respectively inserted into the water storage tank 4 and the purified water tank 5, and the water pumping connection pipe 6 is sequentially provided with the pre-filter 7, the water pumping pump and the reverse osmosis filter 9. The number of the pre-filters 7 can be 3, and the three pre-filters 7 are sequentially connected in series and respectively comprise a PP cotton filter element filter, an activated carbon filter and a PP cotton filter element. In other words, the activated carbon filter is arranged between the two PP cotton core filters, the raw water is primarily filtered through the PP cotton core filters and the activated carbon filter, insoluble impurities and particles in the water are filtered, and a water suction pump and a reverse osmosis filter 9 arranged behind the activated carbon filter play a certain protection role. The number or the type of the pre-filters 7 can be flexibly set according to the purification requirements of water purifiers of different models on water quality, and not only can PP cotton filter cores and activated carbon filters be adopted, but also chemical fiber filter cores and the like can be adopted.
