The rotation of the active pulley 202 causes the connecting belt 206 and the driven pulley 207 to rotate synchronously, thereby causing the connecting rod 203 and the water storage column 204 to rotate synchronously. When the water storage column 204 rotates, the slip ring 17 is driven to slide in the annular groove 16, which is used for the limiting work when the water storage column 204 rotates. At the same time, the rotation trajectory of the water storage column 204 is planned, and the atomizing nozzle 205 is turned on.
