Abstract

The invention discloses an extraction type kitchen faucet. The extraction pipe assembly includes an extraction pipe and a shower head fixedly connected to the extraction pipe. The extraction pipe is provided with a pure water extraction channel and a mixed water extraction channel. One end of the mixed water extraction channel is connected with a first joint water outlet channel. One end of the clean water extraction channel is connected with the water outlet channel of the second joint, and the other end of the clean water extraction channel and the other end of the mixed water extraction channel are connected with the shower head. Since the extraction pipe is provided with a clean water extraction channel and a mixed water extraction channel, both the clean water channel and the mixed water channel can be adjusted at any angle by pulling, which solves the problem that the clean water channel in the prior art adopts a fixed assembly. The problem of inability to adjust the angle and position makes the use of purified water and mixed water more convenient, and the user experience is better.

Description

Removable kitchen faucet

technical field

The present invention relates to a withdrawable kitchen faucet.

Background technique

The existing withdrawable kitchen faucets usually only supply tap water or purified water, and cannot achieve dual water supply. The tap water used in daily life is usually treated by precipitation, chlorination disinfection, filtration and other processes, but the chlorination method still has certain drawbacks, such as heavy metal pollution, poor quality of the water pipe network, and secondary pollution can cause cancer and teratogenicity. With the continuous improvement of the quality of life, people's requirements for water quality are getting higher and higher, and pure water has gradually become an important choice for residents' drinking water. Due to the lack of dual water supply faucets, users can only choose to add additional faucets to supply pure water, or add direct drinking water dispensers.

Or, although there is a drawable kitchen faucet with dual water outlets, only the tap water outlet pipe can be extracted, and the purified water channels are fixed and cannot be extracted or moved, which makes it still inconvenient to use pure water.

Compared with the background technology, the technical solution has the following advantages:

1. Since the extraction pipe is provided with a clean water extraction channel and a mixed water extraction channel, both the clean water channel and the mixed water channel can be adjusted at any angle by pulling, which solves the problem of the fixed water channel in the prior art. The problem of inability to adjust the angle and position due to assembly makes the use of purified water and mixed water more convenient, and the user experience is better.

2. The extraction pipe adopts the pipe-in-pipe structure, which can reduce the diameter of the extraction pipe and ensure the normal extraction.

3. The structure design of the double-water joint is ingenious and concise.

4. The shower head is equipped with a shower water purification water outlet channel and a shower mixed water outlet channel. There is no common part between the water purification water channel and the mixed water channel, so that the water purification water channel and the mixed water channel are completely separated, and there will be no tap water mixed in the purified water. The situation ensures the cleanliness of the water purification waterway.
