Abstract

A bubble blowing device is provided, which connects an output shaft of a motor and a bubble mesh by providing with a deceleration mechanism. The deceleration mechanism can slow down and stabilize the speed of the bubble mesh while the output shaft is rotated at a high speed, thereby reducing a vibration phenomenon of the bubble mesh during operation and improving the smoothness and reliability of the bubble blowing device. Furthermore, by providing the deceleration mechanism in an length extension direction of the output shaft, a torque transmission distance between the output shaft and the bubble mesh can be effectively shortened, thereby avoiding a problem of excessive vibration caused by a long torque transmission distance, it can also render the structure of the entire bubble blowing device more compact, which is not only easy to carry, but also saves storage space.
