Description

Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to a layered reverse osmosis membrane water purifier filter element. Background Art

[0002] The working principle of the layered reverse osmosis membrane water purifier filter is mainly to purify water by applying pressure to the water and utilizing the characteristics of the reverse osmosis membrane; tap water first enters the pretreatment part of the water purifier, which is usually composed of multiple layers of filter screens or filter elements of different materials, such as the common PP cotton filter element; the PP cotton filter element can filter out larger particles of impurities in the water, such as mud, rust, suspended matter, etc., and its filtration accuracy is generally around 5 microns or 1 micron. This step can protect the subsequent reverse osmosis membrane from damage by large particles; the water after preliminary filtration will enter the activated carbon layer, which has a strong adsorption capacity and can adsorb harmful substances such as residual chlorine, organic matter, discoloration, odor, etc. in the water to improve the taste and smell of the water; the pretreated water enters the reverse osmosis membrane assembly, and under the action of the booster pump, a certain pressure is applied to the water (usually 4-10 kilograms of pressure); this pressure allows water to overcome its natural osmotic pressure and flow in the opposite direction of natural osmosis; the reverse osmosis membrane is a semi-permeable membrane with a very small pore size, generally between 0.1 and 0.0001 microns, which can effectively block impurities such as dissolved salts, organic matter, heavy metal ions, bacteria, viruses, etc. in the water; under the action of pressure, water molecules can pass through the reverse osmosis membrane, while other impurities are intercepted;

[0003] When removing the water purifier filter element from the membrane shell, you need to use needle-nose pliers to clamp the force-bearing end on the top of the filter element and forcibly pull it out. When using needle-nose pliers for forced removal, a lot of force is required, and the needle-nose pliers may slip during the operation; this can easily cause the hands to be pinched or scratched, posing a safety hazard to the user.
