Tap for controlling cold and hot water by single valve and conveniently filtering drinking water

Abstract

The invention relates to the water treatment, and provides a tap for controlling cold and hot water by a single valve and conveniently filtering drinking water. The tap comprises a tap body, a cold and hot filter element, a direct drinking filter element, a three-inlet two-outlet valve and a water outlet pipe; a cold water inlet channel and a hot water inlet channel are arranged at the lower partof the tap body; the water outlet pipe is rotationally and tightly connected with the upper part of the tap body; a first water outlet channel and a second water outlet channel communicating with thewater outlet pipe are formed in the upper part of the tap body; a water inlet of the cold and hot filter element is detachably and tightly connected with a water outlet of an outer pipe of the water outlet pipe; an annular blocking ring for blocking a port of a water outlet runner formed between the inner side wall of the outer pipe and the inner side wall of the inner pipe is arranged at the end,far from the tap body, of the water outlet pipe; a water inlet of the direct drinking filter element is detachably and tightly connected with the end, far from the tap body, of the inner pipe of thewater outlet pipe; and a water outlet of the direct drinking filter element is downwards. The tap solves the problems of complicated structure and high production cost in a traditional water purifyingtap.

Description

technical field [0001] The invention relates to plumbing equipment, in particular to a faucet for controlling hot and cold water with a single valve and for easily filtering drinking water. 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 ...
