Abstract
A fluid filled novelty amusement device with a magnetic impeller 9 driven by an electric motor 16, through a magnetic couple created between a magnetic rotor 15 and the magnetic impeller 9, that provides forced circulating fluid 3 flow that entrains and disperses ornamental particles 2 throughout a transparent enclosure 1 to provide viewing entertainment.
Claims6
An improved fluid filled amusement device that comprises:
- a) an enclosure with an opening, said enclosure substantially transparent;
- b) a fluid substantially filling said enclosure;
- c) a plurality of particles disposed inside said enclosure;
- d) a base attached to said enclosure forming a watertight seal between said base and said enclosure, said base having an upper and lower housing, said upper housing hermetically sealed from said lower housing;
- e) an impeller disposed in said upper housing, said impeller further having a plurality of magnetic poles;
- f) a rotor, said rotor rotatably mounted in said lower housing, said rotor further having a plurality of magnetic poles, said rotor closely spaced and aligned to said impeller to form a plurality of magnetic couples;
- and
- g) a drive mechanism disposed in said lower housing, said drive mechanism connected to said rotor to rotate said rotor.
