[0022] Please see Figures 1 to 4This utility model provides a technical solution: an interior decorative paint spraying fixture, including a spray head 1 and a valve body 2. A first connector 3 is threadedly connected to the upper inner side of the valve body 2. The upper end of the first connector 3 is threadedly connected to the lower end of the spray head 1. A first sealing ring 4 abuts between the first connector 3 and the valve body 2. A first connecting pipe 5 and a second connecting pipe 6 are fixed to the outer side of the valve body 2. The interior of the second connecting pipe 6 communicates with the interior of the valve body 2. A second connector 7 is threadedly connected to the lower ends of both the first connecting pipe 5 and the second connecting pipe 6. A second sealing ring 8 abuts between the upper ends of both second connectors 7. A valve core 9 is rotatably connected to the inner side of the valve body 2. A sealing sleeve 10 is fixed to the outer side of the valve core 9. A connection is provided between the outer side of the sealing sleeve 10 and the outer side of the valve core 9. The valve core 9 has a connecting groove 12 inside the hole 11. The bottom surface of the valve body 2 has two slots 13. The lower end of the valve core 9 is coaxially fixed with a rotating shaft 14. A knob 15 is fixed on the outside of the rotating shaft 14. A mounting groove 16 is opened on the side of the knob 15 near the valve body 2. A locking block 17 is slidably connected to the inside of the mounting groove 16. A spring 18 abuts between the locking block 17 and the mounting groove 16. The first connecting pipe 5 and the second connecting pipe 6 are arranged in a symmetrical structure. The inside of the first connecting pipe 5 is connected to the inside of the valve body 2. The inside of the connecting groove 12 is connected to the inside of the connecting hole 11. The inside of the connecting groove 12 is also connected to the inside of the valve body 2. One end of the locking block 17 is engaged with the inside of the slot 13. The first connecting pipe 5 and the second connecting pipe 6 are both L-shaped.

[0023] Two different colors of paint are delivered to two different pipelines via an external dual-pump, dual-pipeline sprayer. These two pipelines are connected to the first connecting pipe 5 and the second connecting pipe 6 via a second connector 7. The interiors of both the first and second connecting pipes 5 and 6 are connected to the interior of the valve body 2. The paint is blocked by the valve core 9 and remains inside the first and second connecting pipes 5 and 6. When the connecting hole 11 on the valve core 9 corresponds to the position of the first connecting pipe 5, the paint in the first connecting pipe 5 enters the valve body 2 through the connecting hole 11 and the connecting groove 12, and then enters the spray head 1 through the first connector 3, thus spraying one color of paint. To switch to the other color, the knob 15 is turned 180 degrees. 5. The locking block 17 is disengaged from one of the slots 13 and engages with the other slot 13. At the same time, the knob 15 drives the valve body 2 to rotate 180 degrees through the rotating shaft 14, so that the connecting hole 11 on the valve body 2 corresponds to the position of the second connecting pipe 6. The paint of another color in the second connecting pipe 6 enters the interior of the valve body 2 through the connecting hole 11 and the connecting groove 12 and enters the interior of the nozzle 1 through the first connecting head 3, thereby performing the spraying of one color of paint. Through the above process, two colors of paint can be quickly switched during paint spraying, which solves the problem that the existing interior decoration paint spraying fixture can only spray one color of paint at a time, and when changing to other colors of paint, it is necessary to empty the internal pigment, which is a cumbersome and inconvenient process.

[0024] The specific usage and function of this embodiment: This utility model uses an external dual-pump dual-pipeline spraying machine to deliver two different colors of paint to two different pipelines. The two different pipelines are respectively connected to the first connecting pipe 5 and the second connecting pipe 6 through the second connector 7. The interiors of the first connecting pipe 5 and the second connecting pipe 6 are both connected to the interior of the valve body 2. Due to the obstruction of the valve core 9, the paint stays inside the first connecting pipe 5 and the second connecting pipe 6. When the connecting hole 11 on the valve core 9 corresponds to the position of the first connecting pipe 5, the paint in the first connecting pipe 5 enters the interior of the valve body 2 through the connecting hole 11 and the connecting groove 12 and passes through the first connector 3. The paint enters the interior of the nozzle 1 to spray one color of paint. When it is necessary to switch to another color of paint, the knob 15 is turned to 180 degrees. The knob 15 drives the locking block 17 to disengage from one of the locking slots 13 and engage with the other locking slot 13. At the same time, the knob 15 drives the valve body 2 to rotate 180 degrees through the rotating shaft 14, so that the connecting hole 11 on the valve body 2 corresponds to the position of the second connecting pipe 6. The paint of another color in the second connecting pipe 6 enters the interior of the valve body 2 through the connecting hole 11 and the connecting slot 12 and enters the interior of the nozzle 1 through the first connecting head 3, thereby spraying one color of paint.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
