The key valve B44 avoids the trouble of inconvenient operation when the hand is stained with impurities such as oil stain and flour by simple pressing operation.

When the cleaning water is needed, the cap 30 is unscrewed, a proper amount of cleaning agent such as detergent is dropped, and then the cap 30 is screwed back. At this time, the key valve a19 is opened, the original tap water flows into the annular cavity (i.e. outer layer pipe) formed by the water outlet pipe 23 and the vertical connecting pipe 24, and becomes clean water after mixing with the cleaning agent, and the clean water flows out from the umbrella-shaped water outlet 48 in an umbrella-shaped spray mode, and the umbrella-shaped water outlet effect is shown in fig. 9, and the umbrella-shaped water outlet angle is alpha. Fig. 5 is a schematic view of the flow of cleaning water, and fig. 6 is a schematic view of the addition of a cleaning agent. The water inlet and temperature adjusting flow channel is shared by common tap water, so the operation mode is the same, and the water can be discharged simultaneously with the common tap water (namely, the key valve A19 and the key valve B44 are opened simultaneously).

The structure has four advantages, namely, the addition of the cleaning agent is convenient; the cleaning water flow channel has large volume, the flow required by spraying water is extremely small, and the cleaning agent can be used for a long time after being added once, so that a liquid storage tank is omitted; thirdly, the angle and the flow rate of the umbrella-shaped effluent can be adjusted by rotating the spray head 40 to change the gap between the plane of the inner hole of the spray head 40 and the outer end surface of the inclined flow passage 47; fourthly, the clean water can be effectively prevented from flowing back into the tap water, and the hidden danger that the drinking water is possibly polluted is eliminated.

It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
