Description

Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a reverse osmosis filter element component. Background Art

[0002] As people's requirements for drinking water quality increase, water purification systems are gradually entering the drinking water system of every household. At present, water purifiers on the market generally use reverse osmosis filter components, which can filter organic matter, colloids, bacteria, viruses and other impurities in raw water, especially inorganic salts, heavy metal ions and other impurities. Therefore, the reverse osmosis filter component constitutes the core component of the water purifier, and the filtering effect and flux of the water purifier are directly related to the structural composition of the reverse osmosis filter component.

[0003] Reverse osmosis is a membrane separation technology that uses pressure as a driving force by means of the function of selective permeable (semi-permeable) membranes. When the pressure applied to the system is greater than the osmotic pressure of the influent solution, water molecules continuously pass through the membrane, flow into the central tube through the water production channel, and then flow out at one end. Impurities in the water, such as ions, organic matter, bacteria, viruses, etc., are retained on the inlet side of the membrane and then flow out at the outlet, thereby achieving the purpose of separation and purification.

[0004] However, relying solely on semi-permeable membranes to filter cannot remove all types of pollutants, especially some small molecular harmful substances, resulting in poor filtering effect. The filtered water quality still has certain safety hazards, and the semi-permeable membrane may be blocked by impurities in the water. Once blocked, the filtering effect will be greatly reduced, and it may even fail to work normally. Therefore, a reverse osmosis filter element component is proposed to solve the above problems.

Subsequently, when the water flows into the interior of the assembly, it will further pass through the semipermeable membrane group 6 to achieve further filtration. The filtered water will eventually be discharged into other pipes through the outlet pipe 4. When the activated carbon inside the outer filter screen 2 and the inner filter screen 5 needs to be replaced, the top cover 3 can be opened for replacement. The top cover 3 is closed by tightening the threads to increase its sealing. When the top cover 3 is covered, the right-angle gasket 7 can be placed at the connection between the top cover 3 and the outer filter screen 2 so that the upper gasket 1 on the right-angle gasket 7 is 1 is inserted into the upper groove 13 on the outer filter screen 2, and the side gasket 2 12 on the right-angle gasket 7 is inserted into the side groove 14 on the inner wall of the outer filter screen 2, so as to ensure the connection and sealing between the top cover 3 and the outer filter screen 2, and then the right-angle gasket 2 8 is placed at the connection between the top cover 3 and the inner filter screen 5, so that the upper gasket 19 on the right-angle gasket 2 8 is inserted into the upper groove 2 15 on the inner filter screen 5, and the side gasket 10 on the right-angle gasket 2 8 is inserted into the side groove 2 16 on the outer wall of the inner filter screen 5, so as to ensure the connection and sealing between the top cover 3 and the inner filter screen 5. Such a design can effectively improve the filtering effect and sealing performance of the filter element assembly, ensure that the filtered water quality meets the standard, and at the same time, it is convenient to replace the activated carbon and extend the service life of the filter element assembly.

At the same time, the side gasket 10 on the right-angle gasket 28 is inserted into the side card groove 216 on the outer wall of the inner filter screen 5, so that the connection between the top cover 3 and the inner filter screen 5 is sealed. When the assembly is fixed, the handle 17 can drive the worm 22 to rotate, and the worm 22 can drive the worm wheel 24 to rotate, and the worm wheel 24 drives the connecting shaft 23 to rotate, so that the connecting shaft 23 drives the rotating disk 21 to rotate, and the arc groove 20 arranged inside the rotating disk 21 will push the column 19 due to the movement, so that the column 19 drives the slider 18 to slide out of the bottom plate 1, so that the filter element assembly is fixed.
