Water purifying filtering element and filtering apparatus thereof

Abstract

The invention discloses a water purifying filtering element. According to a key point of the technical scheme, the water purifying filtering element comprises a filtering element shell, wherein the top end and the bottom end of the filtering element shell are respectively provided with a water inlet end and a water outlet end, a filtering element assembly is arranged in the filtering element shell, and the filtering element assembly successively comprises a filtering layer I, a filtering layer II, a filtering layer III, a filtering layer IV and a filtering layer V from top to bottom; and the filtering layer I is formed by sulfurous acid particles, the filtering layer II is formed by a PP cotton material, the filtering layer III is formed by an AST mixed material, the filtering layer IV isformed by a softened resin material, and the filtering layer V is formed by a rear-mounted active carbon material. The invention aims at providing the water purifying filtering element, which can fundamentally improve the water quality, and achieves a purpose of enabling the water to be directly drunk.

Description

technical field [0001] The invention relates to the field of water purification equipment manufacturing, more specifically, it relates to a water purification filter element and a filter device thereof. Background technique [0002] The water purifier is also called a filter, and its core component is a water purification filter element. The filter layer in the water purification filter element can remove floating objects, bacteria and other harmful substances in the raw water, and then achieve the purpose of direct drinking. With the increasing price of bottled water, more and more users choose to use water purifiers instead of bottled water for drinking. [0003] Although there are many types of water purifiers currently on the market, most of them use ceramic filter elements for filtration and activated carbon adsorption. Although they can reduce impurities in water to a certain extent, they cannot fundamentally improve water quality and do not meet the requirements of he...

Problems solved by technology

[0003] Although there are many types of water purifiers currently on the market, most of them use ceramic filter elements for filtration and activated carbon adsorption. Although they can reduce impurities in water to a certain extent, they cannot fundamentally improve water quality and do not meet the requirements of healthy water. standard; and the water purifier of the prior art, because the size of the water outlet is fixed, the water volume cannot be controlled in a targeted manner. The use intensity of the filter element caused by filtration indirectly shortens the service life of the water purification filter element
