There are manual bubble guns and automatic bubble guns. The manual bubble gun is driven by pulling the trigger by hand, while the fully automatic bubble gun is driven by the motor to drive the tooth wheel.

The movable wheel is divided into two sides to squeeze the hose next to it, mainly by squeezing the hose section by section, and then the water can be pumped up to blow out a long string of bubbles.
