A faucet assembly

Abstract

The invention discloses a faucet component. The faucet component comprises a filtered water control valve and a tap water control valve which are respectively connected with a water supply pipeline to output cold filtered water, hot filtered water, cold tap water and hot tap water; a Venturi effect part is arranged between the water inlet and the water outlet of the water supply pipeline; the local section decreasing part of the Venturi effect part leads to a closed space limited by an elastic deformable flexible diaphragm; the flexible diaphragm is gradually shrunk under the effect of the Venturi effect part in water supply, and can play the backwater effect through negative pressure when the water supply is stopped. Four water flows can be output through the faucet component, the water outlet pipeline is free from water, and the water outlet is free from leakage when a heater is used for heating.

Description

technical field [0001] The invention relates to a faucet assembly. More specifically, the present invention relates to a faucet assembly with no water storage in the water outlet pipe and no dripping at the water outlet when heated. Background technique [0002] Existing mixing faucets usually output water after mixing cold and hot water. However, after the water supply is stopped, a certain amount of water is often retained in the outlet pipe. As a result, the next time the water is supplied, the outlet pipe needs to be emptied first. Especially when hot water is supplied, the cold water in the outlet pipe needs to be discharged before hot water can be supplied, which causes a waste of water resources. Pressure relief and drainage devices are often used in existing faucet assemblies, but their structures are complex and the assembly steps are cumbersome. [0003] There are many types of control valves for existing water faucets. Mixing water valves are often used for mixi...

[0002] Existing hybrid faucets usually output water after mixing cold and hot water. However, after the water supply is stopped, a certain amount of water is often retained in the outlet pipe. As a result, the next time the water is supplied, the outlet pipe needs to be emptied first. Especially when hot water is supplied, the cold water in the outlet pipe needs to be discharged before hot water can be supplied, which causes a waste of water resources

Pressure relief and drainage devices are often used in existing faucet assemblies, but their structures are complex and the assembly steps are cumbersome

[0003] There are many types of control valves for existing water faucets. Mixing water valves are often used for mixing faucets, and the temperature of the water supply can be adjusted through a mechanical handle. However, when multiple water flows need to be supplied, it is difficult to achieve multiple water flow outputs using only a certain valve.
