Embodiment 1

[0031] reverse osmosis membrane filter components, such as Figure 1-Figure 5 As shown, the filter element housing 11 is included, and the filter element housing 11 is provided with a central pipe 12 and a reverse osmosis membrane 13 arranged around the central pipe 12. The central pipe 12 is provided with a central pipe 12 that is divided into an upper pipe 121 and a lower pipe. The water baffle 123 of 122 is provided with a water collecting hole 124 on the wall of the lower pipe 122, and a one-way valve 14 that can cut off the lower pipe 122 and the direction is from top to bottom is provided in the lower pipe 122 and below the water collecting hole 124. The top of the upper tube 121 is a raw water inlet, the side wall of the upper tube 121 is provided with a water outlet 126 communicating with the reverse osmosis membrane 13, and the bottom of the lower tube 122 is a pure water outlet.

[0032] The one-way valve 14 includes a one-way valve housing 141 fixed on the pipe wall...

Embodiment 2

[0049] Same as embodiment 1, the difference is that the bottom of the drain rod 15 is not provided with a limit groove 152, and the wall of the central tube 12 is not provided with a limit pin 125. There are a plurality of protruding points 153 evenly arranged around the drain rod 15 , and there is a gap between the protruding points 153 and the inner wall of the central pipe 12 .

Embodiment 3

[0051] The same as embodiment 1, the difference is that the bottom of the drain rod 15 is provided with a downwardly opening limiting groove 152, and the wall of the central tube 12 is provided with a limiting pin 125 that cooperates with the limiting groove 152. No bumps 153 are provided on it.

Abstract

The invention relates to water purification equipment and discloses a reverse osmosis membrane filter element assembly and a water purifier with the reverse osmosis membrane filter element assembly. The reverse osmosis membrane filter element assembly comprises a filter element shell body (11), wherein the filter element shell body (11) is internally provided with a central pipe (12) and a reverse osmosis membrane (13) which is arranged around the central pipe (12); the central pipe (12) is internally provided with a water separation plate (123) for separating the central pipe (12) into an upper pipe (121) and a lower pipe (122); a water collection hole (124) is formed in a pipe wall of the lower pipe (122); and a check valve (14) which can be used for cutting off the lower pipe (122) and is arranged in a direction from top to bottom is arranged in the lower pipe (122) and is located below the water collection hole (124). According to the reverse osmosis membrane filter element assembly provided by the invention, the check valve (14) is arranged in the central pipe (12) of a reverse osmosis membrane filter element and long-time closing of the reverse osmosis membrane is effectively solved; and a water purification device for standard-exceeding TDS (Total Dissolved Solids) of initial output water can be used for enabling the TDS of the output water to meet normal standard requirements, and the health of drinking water of users is guaranteed.

Description

technical field [0001] The invention relates to a water purification device, in particular to a reverse osmosis membrane filter element assembly and a water purifier with the reverse osmosis membrane filter element assembly. Background technique [0002] With the continuous improvement of people's quality of life, environmental safety and health issues have aroused great concern from the public. Due to the pollution of water sources and the flaws of the water supply system, there are impurities and solvents that are not beneficial to human health in people's domestic water, and the safety of drinking water has become one of the main issues that people generally pay attention to. [0003] The use of water purifiers provides people with a solution to the problem of drinking water safety, among which large-flux and fresh drinking water will soon become the mainstream of the water purification industry. However, the current commercially available non-pressure water storage buck...
