Abstract
A water purifier filter core. The invention relates to an inner filtering apparatus of a water purifier and particularly relates to the water purifier filter core used for achieving filtration in a bath shower or a drinking water purifying device. The filter core includes a micro/nano fiber membrane, a filling material, an upper cover, a fixing ring and a lower bottom. The filling material can be various filtering materials. The micro/nano fiber membrane is in a cylindrical structure. A lower bottom is the upper cover of a water inlet having holes. The fixing ring fixes the cylindrical micro/nano fiber membrane through separation boards at the periphery and is connected to the lower bottom which is a solid board. Tap water flows into the filter core through the water inlet having holes. By means of adsorption and filtration by the filling material, water is pressed out under water pressure through the cylindrical micro/nano fiber membrane at the periphery of the filter core, and then is filtered through the end of the micro/nano fiber membrane to obtain purified water. The filter core achieves adsorption and filtration by the filling material and end filtration by the micro/nano fiber membrane to the tap water, so that the filtered tap water is free of harmful substances and also can remove nano particles and bacteria and virus on surface of skin.
