The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are intended to more clearly illustrate the technical solutions of the present invention and should not be used to limit the scope of the invention.

As shown inFIGS.1-7, a faucet with a spray gun includes a faucet housing1, a main valve seat2arranged on the faucet housing1, a main valve core3disposed within the main valve seat2, and a water inlet hole4on the main valve seat2matching the main valve core3. The faucet housing1is provided with several water outlets5, each having a water passage6. Each water outlet5has at least one water outlet port7in communication with and connected to the water passage6. A water passage device is arranged between the water passage6and the main valve seat2. A spray gun device is provided on and connected to the at least one water outlet port7via a connecting pipe8.

To facilitate cleaning deep cavities and moving to clean large objects, the spray gun device includes a handle9, a washing head10located on one end of the handle9and gradually narrowing from a connection point with the handle9, at least one washing hole11located on the washing head10. A connecting pipe8is located on the other end of the handle9. A connecting passage12is located between the handle9and the washing head10for connecting the washing hole11and the connecting pipe8.

The handle9and the washing head10may be integrally formed or assembled separately.

To facilitate the use of the spray gun device and improve holding comfort, one end of the washing head10with the washing hole11is bent outward to reduce a holding angle for users during washing.

To facilitate the placement of the spray gun device, the water outlet5is further provided with a fixed block13. The fixed block has a placement groove14matching the end of the connecting pipe8or the end of the handle9.

To extend the service life of the spray gun device, the handle9is further provided with a protective cover15.
