The semi-enclosed frame 13 is integrally formed, so that the entire housing 1 has better strength and improves the service life of the housing 1. The settings of the bottom plate 14, the side covers 15, and the upper cover 16 facilitate the assembly of the housing 1 and the assembly of components such as the filtration assembly.

[0026] The mounting base 12 is provided with a first mounting cavity 17, and the multi-port valve 2 is arranged in the first mounting cavity 17.

[0027] One end of the filter assembly is also fixedly arranged in the first mounting cavity 17, and the other end passes through the mounting base 12 from top to bottom and extends towards the base 10, so that the filter assembly is arranged above the base 10.

[0028] The filter assembly includes a pre-filter, a reverse osmosis membrane filter 18 and a post-filter 19. The pre-filter, the reverse osmosis membrane filter 18 and the post-filter 19 all include a cylinder base 20 and a cylinder body 21. The cylinder base 20 is fixedly arranged in the first mounting cavity 17, and the cylinder body 21 extends into the first mounting cavity 17 from bottom to top and is detachably connected to the cylinder base 20. For example, a clamping block is arranged on the cylinder body 21, a clamping groove is arranged in the cylinder base 20, the clamping groove is adapted to the clamping block, and the cylinder body 21 is rotationally clamped with the cylinder base 20 through the cooperation of the clamping block and the clamping groove. Such a setting is beneficial to the disassembly and assembly between the cylinder body 21 and the cylinder base 20 and facilitates the replacement of the filter element in the filter assembly. The detachable connection between the cylinder body 21 and the cylinder base 20 is not limited to the above form and can also be other forms, and reference can also be made to the prior art, which will not be elaborated here.

[0029] In this embodiment, the pre-filter includes a PP cotton filter 22 and a CTO filter 23 that are connected in communication. The post-filter 19 is at least one, and the post-filter 19 is a functional filter. Of course, the pre-filter and the post-filter 19 can also be other filters and are not limited to the above one.

[0030] In this embodiment, the support base 11 is provided with a second mounting cavity 24, and a pressure barrel 25 is accommodated in the second mounting cavity 24.

The pressure barrel 25 is the same as the prior art and will not be elaborated here.

[0031] A pressure gauge 26 is arranged between the raw water outlet 4 and the reverse osmosis membrane filter 18. In this embodiment, the pressure gauge 26 is arranged between the PP cotton filter 22 and the CTO filter 23.

[0032] During specific use, as long as the water pressure of the raw water reaches over 1.5 kg, the raw water can flow through the raw water inlet 3, the raw water outlet 4, the PP cotton filter 22, the CTO filter 23, and the reverse osmosis membrane filter 18 in sequence for filtration and purification. The purified pure water from the reverse osmosis membrane filter 18 flows through the post-filter 19, the pure water inlet 5, and the pure water outlet 6 in sequence and enters the pressure tank 25 for storage. The wastewater generated by the reverse osmosis membrane filter 18 is discharged through the wastewater inlet 7 and the second wastewater outlet 9 in sequence. Moreover, under the pressure of the pure water in the pressure tank 25, the wastewater flows back to the multi-port valve 2 through the first wastewater outlet 8 and is discharged through the second wastewater outlet 9. When pure water is needed, the wastewater generated by the reverse osmosis membrane filter 18 enters the wastewater chamber through the wastewater inlet 7 and the first wastewater outlet 8, squeezing the pure water in the pressure tank 25 outwards. The pure water generated by the reverse osmosis membrane filter 18 is also discharged together with the pure water in the pressure tank 25 through the pure water outlet 6.

[0033] The above is only the preferred embodiment of the present utility model and is not intended to limit the present application.
