[0001] This utility model relates to the field of paint atomization technology, specifically a paint atomizer for automotive exterior panel spraying. Background Technology

[0002] A paint atomizer for automotive exterior panel spraying is a device that can evenly spray paint onto automotive exterior panels. Its nozzle adopts a multi-level fine design, which can evenly break the paint into extremely fine particles to ensure a fine atomization effect, making the coating of automotive exterior panels smoother and more uniform, and greatly improving the gloss and texture of the paint surface.

[0003] Existing paint atomizers for automotive exterior panel spraying are widely used, but they lack residual mist recovery devices. After spraying, residual mist adheres to the atomizer nozzle, causing nozzle blockage. Therefore, a paint atomizer for automotive exterior panel spraying is proposed to address the above problem.

An air extraction device 11 is installed at the bottom end of the air pipe 10. A controller 12 is fixedly connected to the top of the paint output device 1 on one side of the connecting pipe 3. The air extraction device 11 includes a fixed frame 111 fixedly connected to one side of the air pump 2. An adsorption filter 112 is engaged inside the fixed frame 111 and passes through the fixed frame 111. An air pipe is fixedly connected to the side of the fixed frame 111 away from the air pump 2. A dust filter 114 is installed on the side of the fan 113 away from the fixed frame 111. An external thread 8 is threaded into the inside of the threaded cylinder 6. Multiple through holes 9 are evenly distributed inside the hollow cylinder 7. The paint output device 1, air pump 2, and fan 113 are all electrically connected to the controller 12. The system consists of the paint output device 1, air pump 2, connecting pipe 3, atomizer 4, nozzle 5, threaded cylinder 6, hollow cylinder 7, external thread 8, through holes 9, air pipe 10, and extraction device 1. 1 and controller 12. After the painting is finished, the paint output device 1 and air pump 2 are turned off. At this time, the controller 12 controls the fan 113 to start. The fan 113 discharges the air in the fixed frame 111, making the fixed frame 111 a negative pressure environment. The outside air mixed with residual mist enters the hollow cylinder 7 through the through hole 9 and enters the inside of the fixed frame 111 through the air pipe 10. It is absorbed by the adsorption filter 112. This design can collect residual mist and prevent residual mist from adhering to the nozzle 5 and causing the nozzle 5 to be blocked.

[0026] A first magnetic ring 13 is embedded and connected to the side of the hollow cylinder 7 away from the atomizer 4. A second magnetic ring 14 is magnetically connected to one side of the first magnetic ring 13. A fixing plate 15 is fixedly connected to the outside of the second magnetic ring 14. A threaded block 16 is fixedly connected to one side of the fixing plate 15 on the inside of the second magnetic ring 14. A cotton block 17 is provided on the outside of the threaded block 16. A threaded groove 18 is opened on one side of the cotton block 17. A connecting rope 19 is fixedly connected to the side of the fixing plate 15 away from the threaded block 16. The first magnetic ring 13 and the second magnetic ring 14 are the same in shape and size. The threaded block 16 is threadedly connected to the inside of the threaded groove 18. The outside of the cotton block 17 is tightly fitted to the inside of the hollow cylinder 7. The side of the nozzle 7 close to the nozzle 5 is tightly fitted to the outside of the nozzle 5. The end of the connecting rope 19 away from the fixing plate 15 is fixedly connected to the outside of the threaded cylinder 6. Through the first magnetic ring 13, the second magnetic ring 14, the fixing plate 15, the threaded block 16, the cotton block 17, the threaded groove 18 and the connecting rope 19, after the device is used, pick up the fixing plate 15 at one end of the connecting rope 19 and insert the cotton block 17 into the inside of the hollow cylinder 7 so that the first magnetic ring 13 and the second magnetic ring 14 are magnetically connected. The cotton block 17 can absorb the nozzle 5 and the paint attached to the inside of the hollow cylinder 7, and can protect the inside of the hollow cylinder 7 to prevent dust from entering the inside of the hollow cylinder 7.

[0027] Workflow: Before use, power on the equipment and install all components. First, screw the hollow cylinder 7 into the inside of the threaded cylinder 6, so that the external thread 8 is threadedly connected to the inside of the threaded cylinder 6. Screw the cotton block 17 onto the outside of the threaded block 16, so that the threaded block 16 is threadedly connected to the threaded groove 18. Then, install the dust filter 114 on one side of the fan 113 and insert the adsorption filter 112 into the inside of the fixing frame 111. This completes the installation of all components on the equipment. When painting the car exterior, start the paint output device 1 and air pump 2 through the controller 12. The air pump 2 inputs high-pressure air into the atomizer 4 through the connecting pipe 3. The paint output device 1 inputs paint into the atomizer 4 through the connecting pipe 3. The atomized paint is then sprayed out through the nozzle 5 to paint the car exterior. After painting is finished, turn off the paint output device 1 and air pump 2. At this time, the controller 12 controls the fan 1. When the device is started, the fan 113 expels air from the fixed frame 111, creating a negative pressure environment. Outside air mixed with residual mist enters the hollow cylinder 7 through the through hole 9 and then enters the inside of the fixed frame 111 through the air pipe 10, where it is absorbed by the adsorption filter 112. The design of the air extraction device 11 and its connecting components can collect residual mist, preventing it from adhering to the nozzle 5 and causing it to become clogged. After the device is used, pick up the fixing plate 15 at one end of the connecting rope 19 and insert the cotton block 17 into the inside of the hollow cylinder 7, so that the first magnetic ring 13 and the second magnetic ring 14 are magnetically connected. The cotton block 17 can absorb the nozzle 5 and the paint adhering to the inside of the hollow cylinder 7, and can also protect the inside of the hollow cylinder 7 from dust entering the inside of the hollow cylinder 7. After the device has been used for a period of time, the cotton block 17 can be unscrewed and replaced to ensure the cleanliness of the cotton block 17.
