Patent ID: 7934911

Claim:
A multi-axis fan driven by magnetic force comprising: a supporting frame having a bottom panel; and a sidewall being formed on and protruding out from the bottom panel; a power source providing power to a spindle being mounted rotatably through the bottom panel of the supporting frame; at least two driven shafts separately mounted rotatably through the sidewall of the supporting frame in different directions, each driven shaft being perpendicular to said spindle, and each driven shaft having a distal end and a proximal end, wherein extension lines of the proximal ends of the driven shafts intersect with each other and with an extension line of said spindle; and a magnetic transmission assembly mounted between the driven shafts and the spindle of the power source and comprising a driving disc mounted securely around the spindle of the power source and has at least three permanent magnets circumferentially equally spaced on an upper side of the driving disc; at least two driven discs, and each driven disc mounted on an end of a corresponding driven shaft, corresponding to the spindle and having multiple permanent magnets circumferentially equally spaced on an upper side of the driven disc wherein the number of the permanent magnets on each driven disc is the same with the number of the permanent magnets on the driving disc, and corresponding surfaces of the permanent magnets on the driving and driven surfaces have the same magnetic polarity; and at least two blade assemblies, and each blade assembly mounted on the other end of a corresponding driven shaft opposite to a corresponding driven disc.
