Abstract:
1. A bubble generating device comprising: (a) a housing having a front opening; (b) a cylindrical body mounted inside the housing inwardly behind the front opening thereof and defining an axis of rotation, the cylindrical body having diametric inlet and outlet formed thereon with the outlet being facing the front opening; (c) an air gate in the form of a cylindrical pipe having diametric inlet and outlet formed thereon, the air gate being snugly received in the cylindrical body and rotatable therein about the axis of rotation between a closed position where the inlet and outlet of the air gate are out of alignment with the inlet and outlet of the cylindrical body, and an open position where the inlet and outlet of the air gate are in alignment with the inlet and outlet of the cylindrical body to define a diametric air passage; (d) a sleeve extending perpendicularly from the outlet of the cylindrical body and having a bubble ring mounted therein in alignment with the outlet of the cylindrical body; (e) a pump driven by an electric motor for pumping a liquid capable of forming bubbles into the sleeve through an aperture at an upper portion thereof; and (f) an air blower driven by the motor for blowing air through an air tunnel, the air passage and the bubble ring; (g) whereby actuation of a trigger mechanism moves the air gate from the closed position to the open position, and activates the motor thereby pumping the liquid into the sleeve to continuously form a film of liquid across the bubble ring in the sleeve, and blowing air at the film of liquid to generate and discharge bubbles through the front opening of the housing.
