The arrangement of the side walls of the clamping arms 1111, which extend outwards from the two sides of the clamping claw 1112, enables the clamp to be stably clamped in the clamping groove, prevents the clamp from being separated from the clamping groove, ensures that the spray head 10 and the gun body 20 are stably connected, and ensures the stability of the overall structure of the spray gun 100.

In the present embodiment, the fixing portion 111 and the fitting portion 211 are each provided in plurality. The fixing portions 111 are provided at intervals at the mounting positions of the head case 11, and the engaging portions 211 are provided at intervals at the connecting end of the gun body case 21.

The number of the fixing portions 111 corresponds to the number of the matching portions 211, and the positions of the fixing portions correspond to the positions of the matching portions. The arrangement of the fixing parts 111 and the matching parts 211 can further ensure the stability of the connection between the gun body 20 and the spray head 10, improve the connection strength of the two parts and ensure the integrity of the spray gun 100.

In addition, an embodiment of the present application also provides an intelligent toilet, which includes a water inlet pipeline and the spray gun 100 described above. Wherein the water delivery passage 22 of the gun body 20 is in communication with the water inlet line.

After the user correspondingly selects a corresponding cleaning mode through a key on the intelligent toilet, the driving motor 232 works, and the driving shaft 2322 rotates to drive the transmission shaft 231 to rotate, so that the connecting shaft 133 of the spray head 10 rotates, and the rotary valve 13 integrally rotates. When the rotary valve 13 is rotated, the water outlet 131 of the rotary valve 13 communicates with one of the diverting ports 153 of the diverting disk 15 to communicate the water spraying passage 1124 with one of the nozzle passages 1123. The water in the water inlet pipeline of the intelligent toilet enters the water spraying channel 1124 through the water delivery channel 22, then enters the accommodating cavity 1133 of the end cover body 113 through the connecting port 1135, and enters the corresponding nozzle channel 1123 through the water outlet 131 and the flow dividing port 153 correspondingly communicated with the water outlet, so that the water is sprayed out of the nozzle opening 1122 correspondingly communicated with the nozzle channel 1123 to clean the user, and the user can select the corresponding cleaning function.
