  • Patent number: 11826669
    Abstract: The top of a ring-like film forming member with an opening receives bubble solution and gravity causes the solution to flow over the protruding surface of a movable member within the opening such that the surface tension of the bubble solution causes a film to form within the opening and over the surface. The movable member is moved out of the way to allow wind from a wind supply to reach the rear of the ring-like member to form and release a bubble. The protruding shape of the surface allows the film to form and in intact as the member is moved. A trigger mechanically connected to the movable member controls the position of the movable member and the energization of the motor which drives the bubble solution supply and the wind supply. Continuous depression of the trigger causes a series of bubbles to be formed and released.

  • Publication number: 20230055009
    Abstract: First and second rotational ring structures each include a plurality of individual circumferentially arranged rings. The structures are spaced from each other and situated in substantially the same plane. A fan creates an airflow through the housing. A liquid dispensing section has conduits which deliver bubble generating liquid onto rings of each of the rotational ring structures. A siphoning mechanism draws bubble generating liquid from a reservoir and to each of said first and second rotational ring structures. A drive mechanism rotates the rotational ring structures. A motor powers the siphoning mechanism, the drive mechanism, and the fan, such that separate continuous bubble streams are created simultaneously.
