Embodiment Construction
[0029] figure 1 It is a mode of the optimal implementation of the closed filter core structure of the present invention. The eccentric nozzle 3a of the upper end cover 2 is connected to the water inlet isolation area outside the hollow cylindrical PP fiber filter layer 7 through the water passage 5a formed by the partition plate 6 and the upper nozzle skeleton water outlet; the other eccentric nozzle of the upper end cover 2 3b communicates with the water outlet isolation area inside the hollow cylindrical PP fiber filter material filter layer 7 through another water passage 5b formed by the partition plate 6 and the central water outlet of the upper water outlet frame. The closed filter core is provided with large and small two protruding arc-shaped tooth buttons 11, which are located on the same circumference, and the angles corresponding to the arc lengths are 95° and 65° respectively. The base for placing the closed filter element is provided with two corresponding inward...

The invention discloses a closed filter element of a water purifier, which relates to the water treatment industry, in particular to the purification of drinking water. The closed filter element comprises a filter material filtering layer, a cylindrical shell, an upper end cover and a lower end cover, wherein the cylindrical shell is in contact fit with the upper and lower end covers to form a closed cavity in which the filter material filtering layer is arranged, and has an axis overlapped with the circle centers of the upper and lower end covers. The closed filter element further comprises a group of equidirectional water gaps and an upper water gap skeleton. The group of equidirectional water gaps are formed on the upper cover end, and the axis of each water gap is parallel to that of the cylindrical shell. The upper water gap skeleton is provided with a water flowing opening, is positioned in the cylindrical shell and is in contact fit connection with the cylindrical shell and the upper end cover respectively to form water flowing channels communicated with isolation areas positioned on the two sides of the filter material filtering layer and the corresponding water gaps. The closed filter element of the water purifier has the advantages that: the filter element is convenient and labor-saving to replace; and a user can autonomously replace the filter element so as to avoid service expenditure caused by the reservation of a professional for replacing the filter element, correspondingly reduce the user cost of the filter element and simultaneously bring convenience to remote users.
Description
technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] At present, water purifiers are relatively popular in China. When drinking water is used, the water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. As more and more impurities are retained by the filter element, the filter element will often become a new source of "pollution", and the filter element mus...
