Patent attributes
The present disclosure provides a bubble machine, including a film forming nozzle, a film covering body disposed on the film forming nozzle, and fan blades. Airflow generated by rotation of the fan blades flows to the film forming nozzle. The film forming nozzle is driven to swing through a drive mechanism. The drive mechanism includes a dial wheel and a swing rod. A rotating shaft is disposed on a middle of the swing rod. The dial wheel is driven to rotate through a driver. During a rotation process of the dial wheel, a first end of the swing rod swings around the rotating shaft, so that a second end of the swing rod drives the film covering body to swing. The film covering body enables bubble liquid to form a film on the film forming nozzle during a swinging process.
