Abstract
A wireless transmission vital capacity examining device includes two induction coils on a stator frame and a rotor frame having a first magnetic area which is mounted to the two induction coils. A rotatable member with rotatable blades has a third connection portion which has a third magnetic area which is magnetically connected to the second magnetic area of rotor frame so as to rotate the rotor frame. The user blows to rotate the blades and the first induction coil outputs a voltage to a processing unit so as to transfer to a value of the vital capacity. The second induction coil provides electric power to the wireless communication unit to transmit the value. The two induction coils are not interfered to each other and the device does not have problem of insufficient voltages.
