[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3, the utility model provides an embodiment: a backpack paint spraying equipment for building decoration and decoration engineering, including a box body 1, a filling port 2 is opened on the top of the box body 1, a motor 3 is fixedly connected to the top of the box body 1, a partition 12 is fixedly connected inside the box body 1, a rotating shaft 11 is fixedly connected to the output end of the motor 3, the outer wall of the rotating shaft 11 is provided with a stirring assembly, the outer wall of the rotating shaft 11 is fixedly connected with a pulley 1 5, a centrifugal fan 8 is rotatably connected inside the box body 1, a pulley 2 6 is fixedly connected to the top of the centrifugal fan 8, a belt 7 is arranged on the outer wall of the pulley 1 5 and the pulley 2 6, a guide plate 10 is fixedly connected inside the box body 1, an air inlet 9 is opened inside the box body 1, an air outlet 13 is opened inside the box body 1, a fixing frame 14 is fixedly connected to one side of the box body 1, a breathable sponge 15 is fixedly connected to one side of the fixing frame 14, a mesh 16 is fixedly connected to one side of the breathable sponge 15, and the stirring assembly includes a stirring blade 4, and the stirring blade 4 is fixedly connected to the outer wall of the rotating shaft 11;

[0034] Specifically, the paint filling port 2 is put into the box body 1, and the output end of the motor 3 drives the rotating shaft 11 to rotate. As the rotating shaft 11 rotates, the stirring blade 4 starts to rotate in the box body 1 at a certain speed and angle. This rotation action makes the paint in the box body 1 fully stirred, and effectively prevents the precipitation and stratification of the paint. While the stirring blade 4 stirs the paint, the rotating shaft 11 also drives the rotation of the pulley 1 5. The pulley 1 5 is connected to the pulley 2 6 through the belt 7, thereby realizing the synchronous rotation of the pulley 2 6. The rotation of the pulley 2 6 drives the rotation of the centrifugal fan 8. The high-speed rotation of the centrifugal fan 8 causes the external air to be sucked into the box body 1 through the air inlet 9, and blown into the interior of the fixed frame 14 through the air outlet 13. The fixed frame 14 serves as a heat dissipation system The core component of the system has a hollow structure inside, which can maximize the heat dissipation efficiency while ensuring the structural strength. A plurality of through holes are provided on the side of the fixing frame 14 facing the back. These through holes allow the air blown in by the centrifugal fan 8 to pass smoothly through the fixing frame 14 and blow toward the back from the through holes, thereby achieving effective cooling and heat dissipation. In order to ensure the comfort of the operator when carrying the box body 1, a breathable sponge 15 is used to isolate the back from the box body 1. The breathable sponge 15 has good air permeability and elasticity, can effectively reduce the pressure on the back of the operator, and improve the comfort of wearing. At the same time, the addition of the mesh cloth 16 further protects the breathable sponge 15, makes it fit the back more closely, and also enhances the stability and durability of the overall structure.

[0035] Reference Figure 4-Figure 6A paint pump 17 is fixedly connected to one side of the box body 1, and the input end of the paint pump 17 is fixedly connected to one side of the box body 1, and a connecting pipe 18 is fixedly connected to the output end of the paint pump 17, and a nozzle 19 is fixedly connected to one end of the connecting pipe 18, and a fixing ring 20 is fixedly connected to the inside of the nozzle 19, and a fixing plate 21 is fixedly connected to one side of the fixing ring 20, and an opening 22 is provided inside the fixing plate 21, and a limiting ring 24 is rotatably connected inside the fixing ring 20, and a baffle 23 is fixedly connected inside the limiting ring 24, and a groove 25 is provided inside the baffle 23, and an adjusting column 27 is fixedly connected inside the baffle 23, and a sealing strip 26 is fixedly connected to one side of the baffle 23, and one side of the sealing strip 26 is attached to one side of the fixing plate 21;

[0036] Specifically, when the thickness of the paint spraying needs to be adjusted, the operator rotates the adjustment column 27 to drive the baffle 23 to rotate, and the slots 25 on the baffle 23 are aligned with the multiple groups of openings 22 with different diameters on the fixed plate 21. The openings 22 on the fixed plate 21 have multiple different diameters to meet different spraying requirements. By adjusting the rotation angle of the baffle 23, the slots 25 are aligned with the openings 22 with different diameters, thereby realizing flexible adjustment of the thickness of the paint spraying. In order to prevent the paint from passing through the surrounding gaps during the spraying process, Overflow, a sealing strip 26 is used to seal between the groove 25 and the fixed plate 21, and the limit ring 24 can fix the baffle 23 inside the fixed ring 20 to prevent it from shifting or shaking during rotation. During the spraying process, the input end of the paint pump 17 is connected to the box 1, which is responsible for extracting the paint in the box 1. Subsequently, the paint is pumped out through the output end of the paint pump 17 and enters the nozzle 19 through the connecting pipe 18. Inside the nozzle 19, the paint is sprayed with appropriate thickness after precise adjustment of the groove 25 and the opening 22.

[0037] Working principle: When the backpack painting equipment for building decoration and decoration projects is used, the paint is first put into the box body 1 through the filling port 2, and then the output end of the motor 3 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the stirring blade 4 to rotate to continuously stir the paint in the box body 1 to prevent precipitation. At the same time, the rotating shaft 11 drives the pulley 1 5 to rotate, and the pulley 1 5 drives the pulley 2 6 to rotate through the belt 7, and the pulley 2 6 drives the centrifugal fan 8 to rotate so that the external air is sucked into the box body 1 through the air inlet 9 and blown into the fixed frame 14 through the air outlet 13. The interior of the fixed frame 14 is a hollow structure, and a plurality of through holes are opened on the side facing the back, so that the air is blown to the back through the through holes for cooling and heat dissipation. When the operator carries the box body 1 on his back, the back and the box body 1 are in contact with each other. The breathable sponge 15 is used to improve the wearing comfort, and the mesh 16 is used to protect the breathable sponge 15 so that it fits the back better. When the thickness of the paint spraying needs to be adjusted, the baffle 23 can be rotated by rotating the adjusting column 27 to align the slot 25 on the baffle 23 with the openings 22 of different diameters. The openings 22 are provided with multiple groups of different diameters on the fixed plate 21. The slot 25 and the fixed plate 21 are sealed by a sealing strip 26 to prevent the paint from overflowing from the surrounding gaps during spraying. The baffle 23 is limited inside the fixed ring 20 by a limiting ring 24. Then the input end of the paint pump 17 draws the paint in the box 1, pumps it out through the output end of the paint pump 17, enters the nozzle 19 through the connecting pipe 18, and then sprays it out from the opening 22.
