[0028] Example 1

[0029] A surface treatment agent spraying device, such as Figures 1 to 4 As shown, the device includes a mobile frame 1. A purification tank 3 is fixed to the top outer wall of the mobile frame 1. A storage tank 2 is fixed to the top outer wall of the purification tank 3. A transfer pump 7 is installed on one side of the top outer wall of the purification tank 3. The suction end of the transfer pump 7 is connected to the bottom end of the storage tank 2 through a pipe. A stirring rod 4 is rotatably connected to the inner wall of the storage tank 2. A motor that drives the stirring rod 4 to rotate is installed on the top outer wall of the storage tank 2. A spiral scraper 5 is fixedly connected to the side wall of the stirring rod 4 through a support rod. The spiral scraper 5 contacts the side wall of the storage tank 2. A support frame is fixed to the top of the mobile frame 1. A spray head 6 is detachably fixed to the top outer wall of the support frame. One end of the spray head 6 is connected to the discharge end of the transfer pump 7 through a pipe. The nozzle 6 is connected by a telescopic hose. A connecting ring 11 is fixed to the outer wall of the nozzle 6. A jet pipe 8 is fixedly connected to the side wall of the connecting ring 11 and surrounds the outside of the nozzle 6. The jet pipe 8 and the connecting ring 11 are interconnected. A fan 10 is installed on the top outer wall of the mobile frame 1. The air outlet of the fan 10 is connected to the connecting ring 11 through a telescopic hose. A jet slit is opened on one side of the outer wall of the jet pipe 8. The jet slit is inclined towards the axis of the nozzle 6, and the inclination angle is not limited. A suction ring 9 is provided on the outside of the jet pipe 8. The suction ring 9 is conical. There is a gap of more than 4 cm between the suction ring 9 and the jet pipe 8. One end of the suction ring 9 is connected to one end of the purification box 3 through a telescopic hose.

[0030] A fan 13 is installed at the end of the purification box 3 away from the spray head 6. A filter plate 12 is fixed to the inner wall of the purification box 3. Multiple water spray pipes 14 are fixed in a straight line on the inner wall of the top of the purification box 3. The multiple water spray pipes 14 are interconnected. Spray holes are provided on the outer wall of the bottom end of the water spray pipes 14. A water pump 16 is installed on the outer wall of the top of the purification box 3. The suction end of the water pump 16 extends into the interior of the purification box 3 and is located below the filter plate 12. The output end of the water pump 16 is connected to the water spray pipes 14 through a connecting pipe.

[0031] During use, the spray head 6 is removed from the support frame and positioned facing the surface to be sprayed. The delivery pump 7 delivers the liquid from the storage tank 2 to the spray head 6 for spraying. Simultaneously, the blower 10 delivers airflow into the jet pipe 8, which sprays out from the jet pipe 8, enveloping the droplets sprayed from the spray head 6 and reducing droplet diffusion. At the same time, the blower 2 13 draws air out of the purification chamber 3, creating a negative pressure in the purification chamber 3. The suction ring 9 then draws in some droplets that have broken through the airflow that envelops the droplets, and the droplets and air enter the purification chamber 3 together. The water pump 16 delivers water located below the filter plate 12 to the spray pipe 14 for spraying, forming a multi-layered "water curtain" inside the purification chamber 3, causing the droplets entering the purification chamber 3 to enter the water. During the painting process, the motor drives the stirring rod 4 and the spiral scraper 5 to rotate. The stirring rod 4 can stir the liquid in the storage tank 2 to prevent sedimentation, and the spiral scraper 5 can scrape off the liquid adhering to the inner wall of the storage tank 2.

[0032] By incorporating a purification box 3, a jet pipe 8, a suction ring 9, a fan 10, a connecting ring 11, and a fan 2 13, the droplets ejected from the nozzle 6 are encapsulated, reducing droplet diffusion. At the same time, the suction ring 9 sucks up some droplets that have broken through the airflow encapsulating the droplets, further reducing droplet diffusion.

[0033] By incorporating a filter plate 12, a water spray pipe 14, and a water pump 16, the liquid droplets entering the purification tank 3 can be directed into the water, while the water can be recycled.

[0034] Example 2

[0035] A surface treatment agent spraying device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 4 , Figure 5 As shown, an annular box 17 is fixed to the outer wall of the top of the stirring rod 4. A sealing plate 18 is rotatably fitted to the inner wall of the top of the annular box 17. The outer wall of the top of the sealing plate 18 is fixedly connected to the inner wall of the top of the liquid storage tank 2. Multiple nozzles 19 are provided on the side wall of the annular box 17. An electric three-way valve 15 is fixedly installed on the outer wall of the top of the purification box 3. The water inlet of the electric three-way valve 15 is connected to the output of the water pump 16. The two water outlets of the electric three-way valve 15 are respectively connected to the spray pipe 14 and the sealing plate 18 through two connecting pipes.

[0036] During spraying, the electric three-way valve 15 connects the water pump 16 to the spray pipe 14, allowing the water pumped by the water pump 16 to enter the stirring rod 4. After spraying is completed, the electric three-way valve 15 connects the water pump 16 to the annular box 17, and the water pumped by the water pump 16 is evenly sprayed into the liquid storage tank 2 through multiple nozzles 19. At the same time, the motor drives the stirring rod 4 and the spiral scraper 5 to rotate, causing the residual liquid in the liquid storage tank 2 to enter the water, and then spray it out through the spray nozzle 6, carrying out the liquid in the spray nozzle 6 and the connecting hose, thereby cleaning the residual liquid and preventing the residual liquid from solidifying inside the device and affecting subsequent use.

[0037] By incorporating an electric three-way valve 15, an annular box 17, a sealing plate 18, and a nozzle 19, residual liquid can be cleaned using water from the purification tank 3 after spraying, preventing residual liquid from solidifying inside the device and affecting subsequent use.

[0038] Working principle: During use, the spray head 6 is removed from the support frame and faces the surface to be sprayed. The delivery pump 7 delivers liquid from the storage tank 2 to the spray head 6 for spraying. At the same time, the blower 10 delivers airflow into the spray pipe 8. The airflow is sprayed out from the spray pipe 8, enveloping the droplets sprayed from the spray head 6 and reducing droplet diffusion. Simultaneously, the blower 2 13 draws air out of the purification chamber 3, creating a negative pressure in the purification chamber 3. The suction ring 9 draws in droplets that have broken through the airflow enveloping the droplets. The droplets and air enter the purification chamber 3 together. The electric three-way valve 15 connects the water pump 16 to the water spray pipe 14. The water pump 16 delivers water located below the filter plate 12 to the water spray pipe 14 for spraying, forming multiple layers of "water" inside the purification chamber 3. The spraying process involves a "curtain" to allow the droplets entering the purification tank 3 to enter the water. During the spraying process, the motor drives the stirring rod 4 and the spiral scraper 5 to rotate. The stirring rod 4 can stir the droplets in the storage tank 2 to prevent sedimentation, and the spiral scraper 5 can scrape off the liquid adhering to the inner wall of the storage tank 2. After the spraying is completed, the electric three-way valve 15 connects the water pump 16 to the annular box 17. The water pump 16 delivers water and sprays it evenly into the storage tank 2 through multiple nozzles 19. At the same time, the motor drives the stirring rod 4 and the spiral scraper 5 to rotate, allowing the residual liquid in the storage tank 2 to enter the water and then spray it out through the spray nozzle 6, carrying out the liquid in the spray nozzle 6 and the connecting hose, thus cleaning the residual liquid and preventing the residual liquid from solidifying inside the device and affecting subsequent use.

[0039] 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.
