Valve core of two-water-way faucet

Abstract

The invention relates to a valve core of a two-water-way faucet. The valve core of the two-water-way faucet comprises a valve shell, a valve handle, a rotor, a driving plate, a movable valve plate anda fixed valve plate. The valve core of the two-water-way faucet is characterized in that the driving plate is limited at the bottom of a rotor and can rotate together with the rotor and slide radially relative to the rotor; a first boss and a second boss are arranged on the top surface of the driving plate; a first groove and a second groove which are separately in sliding fit with the first bossand the second boss are formed in the bottom of the rotor; a radially convex first blocking block and a radially convex second blocking block are arranged on the inner wall of the valve shell to forma first rotation limiting region and a second rotation limiting region between the first blocking block and the second blocking block; when the first boss side protrudes from the peripheral wall of the rotor, the first boss only rotates in the first rotation limiting region; when the second boss side protrudes from the peripheral wall of the rotor, the second boss only rotates in the second rotation limiting region. The coordination of the internal assemblies of the valve core and the regulation and control of the water way are mainly realized through the bosses on the driving plate, so the internal structure of the valve core is greatly simplified.

Description

technical field [0001] The invention relates to a faucet valve core, in particular to a double water channel faucet valve core with a purified water channel and a raw water channel. Background technique [0002] A mixing faucet is a faucet that mixes hot and cold water and regulates the temperature of the water. The internal faucet spool controls the water flow. When in use, you only need to flip the switch lightly with your hand to open it, and then adjust the water temperature by rotating it. With the advent of water purifiers, more and more people choose to separate drinking water from other domestic water. For example, drinking water uses purified water purified by water purifiers, and ordinary mixed water is used for washing vegetables and dishes. Raw water. This method is undoubtedly of great benefit to people's health. In a traditional kitchen, in order to be able to use purified water, a purified water outlet faucet needs to be installed separately, which causes t...

Problems solved by technology

However, in order to prevent the mixing of raw water and purified water, this kind of valve core can only rotate in the plane. In the state of raw water, when it is opened, it is cold water. With the increase of the rotation angle, the cold and hot water are gradually mixed to full hot water. The flow cannot be adjusted under the same outlet water temperature

In addition, in the prior art, there is also a faucet spool that integrates the purified water channel and the raw water channel on one spool and can adjust the flow of raw water at the same water temperature. However, this product has a complex structure and is not reliable. The internal structure of the spool will be damaged if you use force or use it for a long time, which will affect the service life of the spool and even cause accidents such as water leakage, so this kind of spool is extremely unsafe
