Abstract
A magnetically operated fan device includes a fan member rotatably supported on a housing, one or more magnetic members disposed in the housing, a base supported in the housing, a follower rotatably attached to the base and having a frame, an axle rotatably attached to the frame and having one or more eccentric members for increasing moment of inertia of the axle, one or more magnetic members attached to the eccentric member for acting with the magnetic members of the housing, to bias the axle to continuously rotate relative to the frame of the follower. A coupling device may couple the axle to the fan member, to have the fan member to be driven continuously by the magnetic members and the eccentric members.
Claims19
A magnetically operated fan device comprising:
- a housing,
- a fan member rotatably supported on said housing,
- at least one first magnetic member disposed in said housing,
- a base supported in said housing,
- a follower rotatably attached to said base, and including a frame provided thereon,
- an axle rotatably attached to said frame of said follower, and including at least one eccentric member attached to said axle and rotated in concert with said axle, for increasing moment of inertia of said axle,
- a second magnetic member attached to said at least one eccentric member, for acting with said at least one first magnetic member of said housing, to bias and force said axle to continuously rotate relative to said frame of said follower and said housing, and
- means for coupling said axle to said fan member, to have said fan member to be rotated and driven by said axle and by continuous rotation of said second magnetic member and said at least one eccentric member and said axle relative to said frame of said follower and said housing.
