US Patent 9878262 Apparatus for generating bubbles

A bubble generating device. The apparatus may include a housing, a fan device, and a motor operably coupled to the fan device. The motor may rotate the fan device about a rotational axis. The apparatus may further include one, or a plurality, of bubble generating devices that are coupled to the housing. Each of the bubble generating devices may comprise a bubble producing member that converges towards the rotational axis with increasing distance from the fan device. Stated another way, each of the bubble producing members may define an opening that lies on a plane that intersects the rotational axis of the fan device at an oblique angle.
