Embodiment 1

[0032] Such as figure 1 As shown in the filter assembly, the filter assembly includes a fine filter element 1 and a water drive assembly 2 as a fine filter element, wherein the fine filter element 1 is provided with a raw water inlet 3 for raw water to flow into the fine filter element 1, and for concentrated water to flow out The concentrated water outlet 4 of the fine filter element 1 and the pure water outlet 5 for pure water to flow out of the fine filter element 1; the water driving assembly 2 includes a housing 61, and the housing 61 is provided with a pressure-deformable inner tank 62, A first driving space 7 is formed in the inner tank 62, a second driving space 8 is provided between the inner tank 62 and the housing 61, and the second driving space 8 surrounds the inner tank 62 in the housing 61 layout.

[0033] In this embodiment 1, the booster component is applied as a booster pump 9, the water inlet of the booster pump 9 is provided with a booster inlet 11, and th...

Embodiment 2

[0047] The difference between this embodiment 2 and embodiment 1 is that in this embodiment 2, if figure 2 As shown, the water driving assembly is set in the structural form of a box; the central position in the box is provided with an elastic film to divide one side of the space in the box into the first driving space, and the other side is divided into The second driving space.

Embodiment 3

[0049] The difference between this embodiment 3 and embodiment 1 is that in this embodiment 3, if image 3 As shown, the above-mentioned second control valve 13 and third control valve 14 can be integrated in the prior art to implement the application of the control valve in the form of the first combination valve 25 . Similarly, the above-mentioned fourth control valve 15 and sixth control valve 16 can be integrated, and the corresponding control valves can be applied in the form of the second combined valve 26 . Through the application of the first combination valve 25 and the second combination valve 26 , it is possible to simplify and adjust the pipelines in the waterway, so as to meet the requirements of installation and application in different environments.

Abstract

The invention discloses a filtering assembly capable of flushing a bubble film. The filtering assembly comprises a water driving assembly and a fine filtering element; a raw water inlet, a concentrated water outlet and a pure water outlet are formed in the fine filtering element; the fine filtering element further comprises a raw water port communicated with the outside, the water driving assemblycomprises a first driving space and a second driving space, and an elastic deformation part is arranged between the first driving space and the second driving space; a pressurizing assembly is arranged between the water driving assembly and the fine filtering element; the filtering assembly is provided with a pure water making path, an in-core water backflow path, a pure water bubble film path and a pure water backflow path. According to the filtering assembly, the problem of permeation of a reverse osmosis membrane can be solved by utilizing concentrated water remained in the fine filteringelement and pure water stored in the water driving assembly to realize backflow, so that the reverse osmosis membrane is prevented from being soaked in the concentrated water for a long time; and purewater is used for replacing water on the raw water side of the fine filtering element, so that the TDS value of a first cup of water after the water purification system is restarted from a standby state is reduced.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a filter assembly capable of flushing bubble membranes. Background technique [0002] At present, the existing household large-flux RO / NF pure water machines are conventionally rated as 400G, 500G, 600G and other models. Since the core components used in reverse osmosis and nanofiltration water purification are semi-permeable membranes, the water purifiers During standby, the TDS value of the water staying on the raw water side is higher than that of the water staying on the pure water side, so that the salt content of the water on the raw water side can easily penetrate into the water on the pure water side, which will eventually make the semi-permeable membrane on the raw water side and The water salinity concentration on both sides of the pure water side is basically the same. As a result, whenever the water purifier is on standby for a period of time, the TDS value of the f...
