Description

Technical Field

[0002] With the increasing severity of water pollution in recent years, people are paying more and more attention to drinking water in their daily lives. As a result, a large number of household water purifiers have appeared on the market, especially water purifiers with reverse osmosis membranes, which are loved by the general public. This is because reverse osmosis membranes are artificial semipermeable membranes with certain characteristics made by simulating biological semipermeable membranes. They are the core components of reverse osmosis technology. Based on the reverse osmosis phenomenon, that is, under a certain pressure, water can penetrate from the high-concentration side to the low-concentration side through the semipermeable membrane, while other substances such as salt cannot pass through. In addition, the pore size of the reverse osmosis membrane is very small, only a few nanometers, so it can effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter in the water. At the same time, it can also remove most of the bacteria, viruses and other microorganisms. After being treated with the reverse osmosis membrane, the purpose of desalination and purification of water is achieved, and water quality almost equivalent to pure water is obtained. Common reverse osmosis membranes can only filter out impurities such as dissolved impurities, colloids, microorganisms, and organic matter in water, and cannot remove odors and residual chlorine in water, so the filtered water tastes poor or even has a faint odor.

[0003] Therefore, there is an urgent need to improve an outer shell having a reverse osmosis membrane assembly to solve the above-mentioned problems. Summary of the invention

[0021] like Figure 1-Figure 4 As shown, the present embodiment provides an outer shell with a reverse osmosis membrane assembly, comprising a shell 1, wherein the reverse osmosis membrane assembly comprises a reverse osmosis membrane 2 and a carbon rod 3, a central tube 4 is fixedly arranged inside the shell 1, the outer side of the reverse osmosis membrane 2 is in conflict with the inner wall of the shell 1, and the inner wall of the reverse osmosis membrane 2 is in conflict with the outer wall of the central tube 4, the reverse osmosis membrane 2 is fixed accordingly by the central tube 4 and the shell 1, and at the same time, the water to be purified can permeate from one end of the reverse osmosis membrane 2 to the other end, and the soluble impurities, colloids, microorganisms, organic matter and other impurities in the water are filtered through the reverse osmosis membrane 2;

[0022] Further, such as Figure 1-Figure 4As shown, the carbon rod 3 is located inside the central tube 4, and multiple water flow holes 5 are opened on the outer walls of both ends of the central tube 4. One end of the carbon rod 3 is connected to the reverse osmosis membrane 2 through the water flow hole 5. The water to be purified first flows into the reverse osmosis membrane 2 through the water flow hole 5 at one end of the central tube 4, and the pure water purified by the reverse osmosis membrane 2 flows into the central tube 4 through the water flow hole 5 at the other end of the central tube 4. Finally, the purified pure water is filtered for the second time by the carbon rod 3. At the same time, the carbon rod in the technical solution is made of activated carbon material, which can effectively improve the taste of water quality. Users can change the activated carbon rod into a weak alkali filter element carbon rod or make it into a complex strontium filter element carbon rod according to their own needs;

[0023] Going further, Figure 1-Figure 4 As shown, both ends of the central tube 4 are fixedly connected to the limiting blocks 12, and the two limiting blocks 12 are in conflict with the carbon rod 3. The carbon rod 3 is fixed accordingly by the limiting blocks 12 to achieve the purpose of limiting the movement of the carbon rod 3. One end of the shell 1 is fixedly connected to the connection port 13, and the interior of the connection port 13 is provided with a plurality of water inlet chambers 14 connected to the water flow holes 5.
