Pulling type faucet with cold and hot water filtration and drinking water filtration

Abstract

The invention relates to water treatment, and provides a pulling type faucet with cold and hot water filtration and drinking water filtration. The pulling type faucet comprises a faucet body, a directdrinking filtering core, a cold and hot filtering core, a first shell, a second shell, a drawing pipe, a shunt valve, a three-in and two-out valve and a water outlet pipe, wherein a drawing hole channel is arranged at the longitudinal center of the faucet body, and the water outlet end of the drawing pipe penetrates through the drawing hole channel in the faucet body and extends to the water outlet pipe and penetrates out of the water outlet pipe to form a drawable water outlet structure. The second shell comprises an upper shell and a lower shell which are detachably connected, the water outlet of the direct drinking filter core and a first water outlet of the lower shell are in pluggable and sealed connection, direct drinking water flows out of the first water outlet of the lower shell,and a water outlet channel which communicates with a side through hole of a partition plate and a second water outlet of the lower shell is arranged between the outer wall of the direct drinking filter core and the inner wall of the lower shell. The pulling type faucet solves the problems of inflexible use, large occupied space and high manufacturing cost of an existing water purification faucet.

Description

technical field [0001] The invention relates to plumbing equipment, in particular to a faucet with pull-out type cold and hot water filtering and drinking water filtering. Background technique [0002] As we all know, although the tap water used by people has been sterilized and disinfected after it comes out of the water plant, it has been polluted twice when it has been used for many years. At the same time, the tap water contains a large amount of residual chlorine. For algae and bacteria, it can penetrate the cell wall, oxidize its enzyme system (enzyme is a biocatalyst) to inactivate it, and hinder the life activities of bacteria and die. Residual chlorine is also very harmful to the human body. It can cause dryness, breakage, and bifurcation of human hair, as well as bleaching of the skin, exfoliation of the skin layer, and extremely itchy psoriasis allergies. When chlorine is heated, it reacts with organic substances in water to produce carcinogens such as chloroform...

Problems solved by technology

Therefore, it is particularly important to purify tap water before using it. However, at present, faucets for processing and filtering tap water are basically equipped with two control valves to control clean water and tap water respectively. When using it, you need to close one of the outlets and then open the other. , It is troublesome to use, and the two types of water cannot be switched quickly and effectively. At the same time, the structure of the existing pull-out faucet with filter is complex, especially for the cold and hot mixed water and the cold water is filtered through two filter elements. The overall structure of the faucet takes up a lot of space and costs a lot. The cost is high, and it is inconvenient to replace hot and cold filter elements and direct drinking filter elements
