Three-stage filtering water tap

Abstract

The present invention discloses a three stage filter water tap, which comprises a water tap body , on top of which a sleeve is connected; on upper part of which a connecting piece is provided; on casing of the connecting piece a cover lid is provided, which permit the said connecting piece to rotate for fitting; a water outlet tube is connected on the cover lid and a water outlet is provided on the water outlet tube; on the lower part of the water tap body is provided with a water inlet hole and the lower part of the water tap is connected with an inlet tube; the inlet tube is connected with the said water inlet hole;the water inlet hole on the water tap is connected with the water outlet tube through a valve core, on external of which a valve shell is provided; the flower tooth end is provided with a valve core cover; and outside the valve core a hand wheel is provided; and the first-stage filter, the second-stage filter and the third-stage filter in different materials are provided in sequence from bottom up in side the water tap. The present invention has advantages of simple structure, easy to manufacture, the outlet can rotate 360 o and the use of three stage filter structure composed of different filter elements will ensure the safety of use.

Description

technical field [0001] The invention relates to the technical field of faucet manufacture, in particular to a three-stage filter faucet. Background technique [0002] Faucets are basically used every day in the daily life of the family. There are many types of faucets and various manufacturing methods. At present, most faucets are still manufactured by integral casting, but the faucets manufactured by casting method have the following defects: the production process is complicated, the requirements for molds are high, careless operation in the production process will easily lead to scrapping, and the yield is low. High production costs caused by high; there will also be defects such as uneven surface, blisters, loose parts, troublesome polishing and electroplating. Because of the integral casting, all parts except the water channel are solid, resulting in heavy weight, high production cost and large waste of materials. [0003] In addition, the integrally cast faucet will ...

AI Technical Summary

Problems solved by technology

At present, most faucets are still manufactured by integral casting, but the faucets manufactured by casting method have the following defects: the production process is complicated, the requirements for molds are high, and careless operation in the production process will easily lead to scrapping, and the yield rate is low. High production cost caused by high; There will also be defects such as uneven surface, blisters, loose parts, troublesome polishing and electroplating

Due to the integral casting, all parts except the water channel are solid, resulting in heavy weight, high production cost and large waste of materials

[0003] In addition, the integrally cast faucet will pollute the water when the water flows through the faucet, which will affect drinking health. Moreover, most of the existing faucets do not have a filter structure, which cannot guarantee the safety of water quality. Therefore, its structure needs to be further improved.
