Abstract: Provided is a bidirectional magnetic levitation acoustic motor device, including a motor housing and a motor shaft, wherein the motor shaft is arranged at an axis of the motor housing, an end cover is arranged at a bottom end of the motor housing, shaft holes are formed in axes of the motor housing and the end cover, and the motor shaft penetrates through the two shaft holes. With regard to the invention, movement transmission is achieved by means of an electromagnetic effect, and mounting of elastic structures such as a torsion bar and the like is no longer needed, so that on one hand, the situation that the service life of a motor is short due to the fact that the elastic structures are prone to damage during usage is avoided, and on the other hand, the motor in a unit volume can transmit torque in a larger value.

Abstract: The invention relates to the technical field of motors, and in particular to a motor driven mechanism capable of reciprocating extension/retraction and vibration, including an outer frame, a first connecting seat and a second connecting seat. The first connecting seat is provided with an extension/retraction driving component. The second connecting seat is provided with a rotary motor. The rotary motor includes a stator component and a driving shaft. A Hall sensor is arranged between the outer frame and the second connecting seat. The driving shaft is provided with an inductive magnetic ring. According to the invention, the extension/retraction driving component can drive the outer frame to move, and a guide rail drives the driving shaft to move synchronously, so that the driving shaft can extend and retract. Thus, the whole mechanism has a reciprocating extension/retraction function.

Abstract: The disclosure relates to the technical field of blow dryers, and in particular to a compact continuous high-speed blow dryer. By improving optimized design of an air duct, while a wind resistance coefficient of guide vanes is reduced, values of flow rates in paths can be ensured, so that a fluid can be led out of the air duct linearly and uniformly and a fan blade can operate stably. Auxiliary support structures such as a spring, bearings and an air guide pad further stabilize a position of the fan blade and avoid centrifugal vibration of the fan blade, which eventually reacts on a rotating shaft and affects rotational efficiency of the rotating shaft. Therefore, an operating environment of the fan blade is greatly improved, and overall efficiency of the fan is improved, Moreover, since the operating environment of the fan blade is optimized, stability of the fan is enhanced, and further, service life of the fan is prolonged.
