Description

Technical Field

[0001] The utility model relates to the technical field of drinking water treatment, in particular to a drinking water filter element. Background Art

[0002] The drinking water filter element is the heart of the water purification device. As the name suggests, the filter element is a purification equipment required to purify the original ecological resources and reuse the resources. The filter element is generally used in oil filtration, water filtration, air filtration and other filtration industries to remove a small amount of impurities in the filter medium to protect the normal operation of the equipment or the cleanliness of the air. When the fluid passes through the filter element with a certain precision in the filter, its impurities are blocked, and the clean fluid flows out through the filter element.

[0003] For example, a drinking water filter element and drinking water device with application number 202020549662.5, the device isolates the filter material space and the slow-release agent space by setting a detachable cover, and sets the slow-release agent space close to the water outlet channel. Because there is a large filter screen below the slow-release agent space, it is not easy to be blocked; and because it is located below the filter material, the calcium and magnesium ions released by the slow-release agent will flow into the filtered water along the water flow and no longer contact the original filter material, thus avoiding the calcium and magnesium ions being reabsorbed by the filter material. However, it is difficult for the device to replace the filter components without affecting the normal operation of the drinking water device. In addition, combined with the existing filter elements, it is found that most of the existing filter elements are of invisible internal design, which makes it difficult to replace them in time according to the actual use of the filter element.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a drinking water filter element is proposed. Utility Model Content
