[0003] Announcement No. CN219597056U proposes a spraying device with an anti-drip structure. This solves the problem that current spraying devices on the market lack an anti-drip structure, causing paint residue to drip from the nozzle after spraying, sometimes even onto the battery box, affecting its appearance and requiring repainting, thus reducing spraying efficiency and user inconvenience. Furthermore, the anti-drip structure is difficult to retract, reducing the overall practicality of the device. The device includes a worktable with two side plates fixed to its top, a top plate between the side plates, and a connecting rod fixed to the bottom of the top plate. A spraying component is located at the bottom of the connecting rod, and a fixing rod is fixed to the side of the connecting rod.

The small servo motor 609 is connected to the front of the hopper 602 via a motor mount.

[0026] In practice, the large servo motor 606 is started to drive the large worm gear 605 to rotate the large worm wheel 604. The large worm wheel 604 drives the support plate 601 to rotate on the sprayer 4, rotating the hopper 602 to below the sprayer 4. At the same time, the small servo motor 609 is started to drive the small worm gear 608 to rotate the small worm wheel 607, causing the hopper 602 to rotate on the support plate 601, keeping the hopper 602 always vertical and storing the paint dripping from the sprayer 4.
