[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] This embodiment is a spray gun structure that is easy to replace.

[0021] like Figure 1-4As shown, it includes a feeding pipe 1, with a discharge port 4 at one end of the outer surface of one side of the feeding pipe 1. A switching assembly 2 is fixedly installed on the outer surface of one end of the feeding pipe 1. A nozzle assembly 3 is connected to the outer surface of one end of the switching assembly 2. The switching assembly 2 includes a mounting shell 5, a rotating shaft 6 and a reduction motor 7. The nozzle assembly 3 includes a ring body 8, a connecting shaft 9, a turntable 10, a spray gun head 11 and a sealing ring 12. The mounting shell 5 is fixedly installed on the outer surface of one end of the feeding pipe 1.

[0022] The geared motor 7 is fixedly installed inside the mounting housing 5. The rotating shaft 6 is connected to the outer surface of one end of the geared motor 7, and the outer surface of the rotating shaft 6 away from the geared motor 7 is fixedly connected to the middle of the outer surface of one side of the turntable 10. A sealed bearing is provided between the rotating shaft 6 and the mounting housing 5. The rotating shaft 6 is rotatably connected to the mounting housing 5 through the sealed bearing. A coupling is provided between the rotating shaft 6 and the geared motor 7. The outer surface of one end of the rotating shaft 6 is fixedly connected to the outer surface of one end of the output shaft in the geared motor 7 through the coupling. There are four sets of connecting shafts 9, spray gun heads 11, and sealing rings 12. The ring body 8 is rotatably connected to the outer wall of one end of the feeding pipe 1. The four sets of connecting shafts 9 are fixedly installed between the outer surface of one end of the ring body 8 and the outer surface of one side of the turntable 10. The four sets of spray gun heads 11 are fixedly installed on the outer wall of the ring body 8. The sealing rings 12 are connected to the outer surface of one end of the spray gun heads 11, and the sealing rings 12 are fixedly installed on the inner wall of the ring body 8.
