Filter element and water purifier

Abstract

The invention discloses a filter element and a water purifier. The filter element comprises a shell, an activated carbon filter felt layer and at least one silver-loaded activated carbon antibacterialparticle layer, wherein the activated carbon filter felt layer is arranged in the shell and has a cylinder-shaped structure; the silver-bearing activated carbon antibacterial particle layers are arranged in the activated carbon filter felt layer. The filter element is prepared by replacing a granular activated carbon absorption material with activated carbon fibers having high specific areas andhigh adsorption performance, and the activated carbon fiber felt layer wound into the cylinder-shaped structure is internally provided with the silver-loaded activated carbon antibacterial particle layer, so that not only are the absorption purification efficiency and the bacteriostatic effect during absorption purification guaranteed, but the volume and consumption of a filter material is also reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of water purification, more specifically, to a filter element and a water purifier. Background technique [0002] The development of water purifiers in the international market is quite mature. Some experts pointed out that in developed countries such as Europe and the United States, the penetration rate of household water purifiers has exceeded 80%. However, in my country, the current penetration rate of household water purifiers is still less than 10%. . However, it is worth noting that in recent years, with the improvement of consumption level and people's quality of life, Chinese consumers' demand for household water purification has continued to rise. China's water purification industry has begun to show rapid growth. on the road to popularization. According to GB / T30307-2013 "Drinking Water Treatment Devices for Household and Similar Purposes" 5.6.1 Purified Water Quality Requirements: The purified wa...
