Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0034] Refer below Figure 1-Figure 3 A filter assembly 100 according to an embodiment of the first aspect of the present invention is described. The filter assembly 100 can be applied to water purification equipment (not shown in the figure) such as a water purifier. In the following description of the present application, the application of the filter assembly 100 to water purification equipment such as a water purifier is taken as an example for illustration. Of course, those skilled in the art can understand that the filter assembly 100 can also be applied to other equipment, not limited to water purification equipment.

[0035] Such as figure 1 As shown, the filter assembly 100 according to the embodiment of the first aspect of the present inventio...

Abstract

The invention discloses a filter assembly and water purification equipment with the filter assembly, the filter assembly comprises a central pipe and a reverse osmosis film, a first partition plate divides the interior of the central pipe into a liquid outlet cavity and a treatment cavity, the treatment cavity is internally provided with a filter material for reducing the TDS value, and the central pipe is provided with a first on-off device and a second on-off device. The first on-off device is configured to be in an open state when the pressure acting on the side, away from the center of the central pipe, of the first on-off device is larger than the closing pressure of the first on-off device, so that the exterior of the central pipe communicates with the liquid outlet cavity; the second on-off device is configured to be in a closed state to cut off communication between the outside of the central pipe and the processing cavity when the pressure acting on the side, away from the center of the central pipe, of the second on-off device is larger than the opening pressure of the second on-off device, so that the outside of the central pipe is prevented from being communicated with the treatment cavity; According to the filtering assembly, the situation that the TDS value of the first cup of water is too high when the water purifier is started can be effectively avoided. In addition, automatic switching between a treatment water path and a pure water path can be achieved.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a filter assembly and a water purification equipment with it. Background technique [0002] In the related art, when the water purifier is turned on, the booster pump will exert pressure on the incoming water on one side of the reverse osmosis membrane. When the pressure exceeds the osmotic pressure of the reverse osmosis membrane, the solvent will permeate against the direction of natural penetration. Produces pure water with low TDS (Totaldissolved solids, total dissolved solids). However, since the external pressure provided by the booster pump will disappear when the water purifier is turned off, the reverse osmosis will return to natural osmosis, and the TDS at the feed water and concentrated water end will diffuse to the pure water end, making the pure water stored between the reverse osmosis membranes The TDS value of the water rises, resulting in a h...
