Cold and hot water purifying faucet

Abstract

The invention relates to a cold and hot water purifying faucet. The cold and hot water purifying faucet comprises a cold and hot valve, a shell, a water purifying filter element and a water outlet, wherein the shell is of a detachable hollow structure, the water purifying filter element is located in the hollow structure of the shell and comprises an upper cover body located at the upper end, a lower cover body located at the lower end, a polyester fiber film, a carbon nanofiber film, a nano-ion sieve and KDF, a water outlet through hole which penetrates through the upper cover body is formed in the upper cover body, the polyester fiber film is located on the outermost side of the filter element, the carbon nanofiber film is located on the inner side of the filter element, and the space between the carbon nanofiber film and the polyester fiber film is filled with the nano-ion sieve and the KDF. According to the cold and hot water purifying faucet, an efficient washing structure is adopted, pollutants blocked by the filter element can be effectively washed away, the filter element is prevented from being blocked, it is guaranteed that water is purified, the faucet can be used repeatedly after being washed, and the service life of the filter element is prolonged.

Description

technical field [0001] The invention relates to a domestic tap water faucet, in particular to a hot and cold water purification faucet capable of realizing clean water. Background technique [0002] For a long time, secondary pollution of municipal tap water caused by pipelines and storage tanks has plagued people's lives. Tap water comes out of the waterworks and is transported to users through pipelines, and water from some multi-storey and high-rise buildings enters tens of thousands of households through water tank storage and other links. Secondary pollution of tap water is formed due to factors such as aging pipelines, rust and scale in the pipe walls, and unclean water tanks. Secondary pollution not only leads to obvious abnormalities in indicators such as chromaticity and turbidity of tap water, but also causes impurities such as insects and mites, colloidal suspended solids, and organic matter to exist in tap water, as well as microorganisms and bacteria.

Problems solved by technology

In the prior art, ceramic filter cores are usually used as filter cores. The water output of ceramic filters is small, the volume is large, and the manufacturing process is complicated, resulting in high product costs. Moreover, after a period of use, the ceramic core filter is not ideal.

In addition, the existing water purification structure is single, the water purification effect needs to be improved, and the filter element needs to be replaced frequently, which is inconvenient to use and high in cost
