Tap module

Abstract

The invention discloses a tap module connected to a water supply pipeline. The tap module comprises a running water cold/hot water pipeline and a filter water supply pipeline, wherein the running water cold/hot water pipeline comprises a first water outlet for outputting running water hot water or cold water; the filter water supply pipeline comprises a cold water supply pipeline and a hot water supply pipeline connected in parallel and independent from each other; the cold water supply pipeline comprises a first water inlet pipeline and a first water outlet pipeline; the first water outlet pipeline is connected with a second water outlet; the hot water supply pipeline comprises a second water inlet pipeline, a venturi effect part, a heater and a second water outlet pipeline; the second water outlet pipeline is connected with a third water outlet; a flexible diaphragm gradually shrinks under the effect of negative pressure generated by the venturi effect part in water supply; and the water returning is finished under the effect of atmospheric pressure when the water supply is stopped. Filter cold water and hot water independent pipes control the water drainage, so that users have no need to wait for cold and hot water reflux time during operating to achieve the effect of instant use during opening.

Description

technical field [0001] The invention relates to a water faucet assembly, in particular to a water faucet assembly in which the outlet water of each pipe does not interfere with each other, and there is no water storage in the filtered hot water outlet pipe. 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. [0003] Existing four-flow faucet, that is, the faucet can come out of tap water cold water, tap water hot water, filtered water cold water, filtered water hot water four kinds of currents. The outlet pipe of the existing four-flow faucet usually ad...

Problems solved by technology

Since the tap water from the outer tube has no function of returning water, there is a large amount of accumulated water in the tube. When filtered water and hot water are discharged, the inner tube wall heats up rapidly. The inner tube is equivalent to the heating tube heating the tap water of the outer tube. Expansion, dripping water from the faucet outlet, causing water leakage, and also causing the temperature of the hot water to drop
