[0003] After searching, the patent (application number: 202220612659.2) discloses "a water-saving reverse osmosis water purifier". The device solves the problem that the previous filter component is disc-shaped by setting an improved filter component. This filtering method is too simple and cannot filter cleanly, which makes the water purification time longer and cannot increase the purification speed, reducing the applicability. However, the device has the following problems in actual use:

[0004] First, the water purification structure in the device is concentrated in a water purification tank. Not only is it unknown what specific water purification method and what materials are used for water purification, but the water purification materials are also inconvenient to replace.

[0005] In addition, the device has only one way of discharging water, and cannot adjust the water quality according to specific water demand. All water purification devices need to be used for each purification, which can easily reduce the service life of the water purification devices. Utility Model Content

A wastewater pipe is connected to the bottom of the outer wall of the reverse osmosis filter element, and a post-activated carbon filter element is connected to one side of the reverse osmosis filter element, and a direct drinking water pipe is connected to the water outlet of the post-activated carbon filter element.

[0025] In this embodiment, five different filtering devices are added to the device, and the primary PP filter element 2, the pre-activated carbon filter element 3, the secondary PP filter element 4, the reverse osmosis filter element 7 and the post-activated carbon filter element 9 are connected in sequence, which not only ensures the water purification effect, but also the five filtering devices can be installed separately, simple to disassemble and convenient to replace.

[0027] In this embodiment, three different water outlet modes are adopted, namely, purified water flowing out from the purified water pipe 5, wastewater flowing out from the wastewater pipe 8, and pure water flowing out from the direct drinking water pipe 10. The pure water is obtained by separating the wastewater from the purified water. When in use, different water outlet modes can be selected according to different water quality requirements. It is not necessary for all purification devices to work together, which saves water purification costs and increases the service life of the filtering device.

In order to further filter the purified water, the purified water will be further purified by the reverse osmosis filter element 7, and the waste water filtered out by the reverse osmosis filter element 7 will be discharged from the waste water pipe 8. Finally, the pure water passing through the reverse osmosis filter element 7 will be discharged from the direct drinking water pipe 10.
