Filter element for water purifier

Abstract

The invention relates to water treatment industry, in particular to the aspects of depth-type filtration and purification of drinking water. The invention discloses a filter element for a water purifier, wherein the water inlet and the water outlet of the filter element are arranged on the symmetrical alternative positions relative to the symmetric center. The invention has the following advantages: the back flush of the filter element is relatively thorough and has good effect, thus well preventing secondary pollution to the filter element, and impurities can be discharged from a water purification pipeline directly, thus the back flush effect is absolutely clear. As the filter element can be replaced conveniently, a user can purchase the filter element and replace the filter element by self, thus being benefit for the popularization of the water purifier, avoiding the inconvenience caused by the fact that the filter element can be replaced only by professionals and service expenditure, correspondingly reducing after service cost of the water purifier and the filter element and facilitating 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, the use of water purifiers has been popularized to a certain extent in China. When using water, the water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. Due to the high cost of purchasing and using water purifiers, among all types of models, water purifiers with medium and low prices are more popular. However, along with the popularization of water purifiers, their defects and deficiencies in application are gradually exposed: after the filter element of the water purifier is used for a period of time, the filter element filter material is gradually blocked by impurities and adsorbed on the outer surface of the filter material As a result, the filtering and adsorption effects are significantly r...

Problems solved by technology

No matter how big it is, it's hard to operate

Even if a small-diameter post-processing filter element is set in the remaining space around a group of main independent filter elements, the height of the filter element cannot be increased due to the height limit of the whole machine, and its correspondingly too small volume cannot match the main filter element, resulting in extremely short life. The vast majority of water purifiers adopt a single-row low configuration mode with fewer filter elements and a larger diameter; mid-range and high-end models adopt a single-row high configuration mode with small diameter and multiple filter elements

In addition, if the vertical configuration of the filter element is changed to a horizontal configuration, although it is more convenient to extract the filter element, due to the influence of gravity, the filtering effect of the cross-section of the filter element layer is not uniform, especially for the filter layer using activated carbon filter material. Material throwing and tumbling space

When it is placed horizontally, due to the weight of the filter material itself, it is arranged in an upper small and lower large arrangement, which directly affects the filtering effect.

Above-mentioned defect and deficiency have a strong impact on the popularization of water purifier
