Abstract
A device that creates micro or small-sized bubbles that resemble snow. The microbubble-producing device includes a shaft with a microbubble-producing solution reservoir connected to one end and a housing connected to a second end. The housing contains a motor, a pump, and an air-producing device, which are electrically connected to a power source. An air duct is connected on one end to the air-producing device and another end to a microbubble emitter. The emitter is hollow and includes an exterior wall. Secured to an inner surface of the wall is a shelf, which contains at least one orifice. A microbubble-producing solution input channel is a tubular structure with a first end submerged within the microbubble-producing solution reservoir and a second end connected to the shelf through the wall of the emitter.
