The faucet housing 1 is provided with several water outlets 5, each having a water passage 6. Each water outlet 5 has at least one water outlet port 7 in communication with and connected to the water passage 6. A water passage device is arranged between the water passage 6 and the main valve seat 2. A spray gun device is provided on and connected to the at least one water outlet port 7 via a connecting pipe 8.


To facilitate cleaning deep cavities and moving to clean large objects, the spray gun device includes a handle 9, a washing head 10 located on one end of the handle 9 and gradually narrowing from a connection point with the handle 9, at least one washing hole 11 located on the washing head 10. A connecting pipe 8 is located on the other end of the handle 9. A connecting passage 12 is located between the handle 9 and the washing head 10 for connecting the washing hole 11 and the connecting pipe 8.


The handle 9 and the washing head 10 may be integrally formed or assembled separately.


To facilitate the use of the spray gun device and improve holding comfort, one end of the washing head 10 with the washing hole 11 is bent outward to reduce a holding angle for users during washing.


To facilitate the placement of the spray gun device, the water outlet 5 is further provided with a fixed block 13. The fixed block has a placement groove 14 matching the end of the connecting pipe 8 or the end of the handle 9.


To extend the service life of the spray gun device, the handle 9 is further provided with a protective cover 15.
